Laparoscopic total colectomy for acute colitis: a case-control study.

INTRODUCTION: There are no previous comparative studies of total abdominal colectomy by laparoscopic methods in ulcerative colitis and Crohn's disease patients requiring urgent colectomy. This study aimed to determine the safety and efficacy of laparoscopic colectomy in these patients compared with those undergoing conventional urgent colectomy. METHODS: Patients undergoing laparoscopic total colectomy for acute colitis were identified in a prospective registry. All patients underwent a total colectomy with creation of an end ileostomy and buried mucous fistula. No patient had fulminant disease (tachycardia, fever, marked leukocytosis, peritonitis), but all were failing to respond to medical treatment. Patients undergoing conventional total colectomy were matched for age, gender, body mass index, diagnosis, disease severity, and operative period. Median values (range) are listed. RESULTS: From 1997 to 1999, there were 19 laparoscopic and 29 matched conventional patients. There were no inadvertent colotomies or conversions in the laparoscopic group. Although there was no difference in operative blood loss in the laparoscopic group (100 (range, 50-700) ml) when compared with the conventional group (150 (range, 50-500) ml), the operative times were significantly longer in the laparoscopic group (210 (range, 150-270) vs. 120 (range, 60-180) minutes, P < 0.001). Bowel function returned more quickly in the laparoscopic group (1 (range, 1-3) vs. 2 (range, 1-4) days; P = 0.003) and the length of stay was shorter (4 (range, 3-13) vs. 6 (range, 4-24) days; P = 0.04). Complications occurred in three (16 percent) laparoscopic patients (2 wound infection and 1 ileus) and in seven (24 percent) conventional patients (3 wound infection, 3 deep venous thrombosis, 1 upper gastrointestinal bleed). CONCLUSIONS: Laparoscopic total colectomy is feasible and safe in patients with acute nonfulminant colitis and may lead to a faster recovery than conventional resection.

Subtotal colectomy vs. intraoperative colonic irrigation in the management of obstructed left colon carcinoma.

PURPOSE: Whether primary anastomosis should be performed after segmental resection with intraoperative colonic irrigation or subtotal colectomy is not yet established in the surgical treatment of obstructive left colon carcinoma. In this prospective, nonrandomized study, we present the results of 66 patients undergoing one-stage surgery for obstructed left colon carcinoma. PATIENTS AND METHODS: We compared two techniques, subtotal colectomy (35 patients) and intraoperative colonic irrigation with segmental resection and immediate anastomosis (31 patients). RESULTS: The mortality rate was similar in both groups, 8.5 percent in the subtotal colectomy group and 3.2 percent in the intraoperative colonic irrigation group. The surgical complication rate was significantly higher in the intraoperative colonic irrigation group (41.9 percent) than in the subtotal colectomy group (14.2 percent; P < 0.05). Mean operating time was significantly lower in the subtotal colectomy group than in the intraoperative colonic irrigation group (P < 0.05). Both groups had a similar mean duration of hospital stay. Ten patients who underwent subtotal colectomy (31.2 percent) presented with diarrhea in the immediate postoperative period, which disappeared spontaneously or with antidiarrheal medication; a disabling diarrhea persisted in two patients only (6.2 percent). CONCLUSION: We believe that subtotal colectomy is the treatment of choice for obstructed left-sided colonic carcinoma. Segmental resection with intraoperative colonic irrigation is more appropriate than subtotal colectomy only in patients with carcinomas of the rectosigmoid junction or with previous anal incontinence to avoid the appearance of postoperative diarrhea.

Laparoscopic-assisted vs open colectomy for severe acute colitis in patients with inflammatory bowel disease (IBD): a retrospective study in 42 patients.

BACKGROUND: Inflammatory bowel disease (IBD) can be complicated by severe acute colitis. Emergency colectomy is mandatory if patients do not respond to intensive medical therapy. A minimally invasive approach such as laparoscopic-assisted colectomy might be beneficial in these patients. Therefore, we set out to assess the feasibility and the safety of emergency laparoscopic-assisted colectomy in IBD patients with severe acute colitis. METHODS: A total of 42 consecutive patients underwent an emergency colectomy with end-ileostomy. Ten patients had laparoscopic-assisted colectomy, and 32 had open colectomy. Pre- and perioperative parameters, morbidity, and mortality were analyzed. RESULTS: The two groups were comparable for patient characteristics. There were no conversions in the laparoscopic group. The operation time was longer in the laparoscopic group than in the open group (271 vs 150 min; p < 0.001), but the hospital stay was shorter (14.6 vs 18.0 days; p = 0.05). Complications were similar for the two groups. CONCLUSION: Laparoscopic-assisted colectomy in IBD patients with severe acute colitis is feasible and as safe as open colectomy.

Cost structure of laparoscopic and open sigmoid colectomy for diverticular disease: similarities and differences.

PURPOSE: Although laparoscopic colectomy has demonstrated a variety of advantages, it remains unclear whether the reductions in length of stay and faster return of bowel function will offset potential increases in cost caused by operating time and instrumentation. The purpose of this study was to compare the direct cost structure of elective open and laparoscopic resection for sigmoid diverticulitis. METHODS: We compared consecutive elective open and laparoscopic sigmoid colectomies (n = 71 and n = 61, respectively) performed from March 1, 1999, through December 31, 2000. Data collected included age, gender, body mass index, American Society of Anesthesia score, indication for surgery, morbidity, mortality, conversion (laparoscopic only), operating time, and length of hospital stay. Direct cost data were provided by Stanford's integrated hospital cost management and decision software. Indirect costs and total costs were not addressed. Data were analyzed by Student's t-test and chi-squared test where appropriate. Significance was set at P < 0.05. All data are presented as mean +/- standard error of the mean. RESULTS: There were 132 elective sigmoid colectomies for diverticular disease (61 laparoscopic and 71 open procedures). There were no significant differences between the groups with respect to age, male/female ratio, or body mass index. Operating time was similar (109 +/- 7 minutes for laparoscopic procedures vs. 101 +/- 7 minutes for open procedures). The laparoscopic group had a significantly shorter length of stay (3.1 +/- 0.2 vs. 6.8 +/- 0.4 days), fewer pulmonary complications (1 (1.6 percent) vs. 4 (5.6 percent)) and fewer wound infections (0 vs. 5 (7 percent)). Conversion to open colectomy was required in 4 (6.6 percent) of 61 patients. Readmission occurred in three laparoscopic colectomy patients (4.9 percent) and four open colectomy patients (5.6 percent). There was one operative death in the laparoscopic group (1.6 percent) and no deaths in the open group. Total direct cost per case was significantly less for laparoscopic procedures ($3,458 +/- 437) than for open colectomies ($4321 +/- 501; P < 0.05, Student's t-test), and operating costs were not significantly different between the groups. CONCLUSION: The data demonstrate that laparoscopic colectomy is a cost-effective means of electively managing sigmoid diverticular disease. This operative approach may become very important in an era of increasing constraints on hospital occupancy rates and access to nursing services in many regions of the country.

Laparoscopic sigmoid colectomy after acute diverticulitis: when to operate?

BACKGROUND: Laparoscopic sigmoid colectomy has become an acceptable method of surgical treatment for diverticulitis. However, an optimal waiting period before attempting elective laparoscopic colectomy has not been established. We sought to evaluate the relationship between the time interval from an acute episode of diverticulitis to laparoscopic colectomy and surgical outcomes. METHODS: All patients undergoing laparoscopic colectomy during a period of 10 years in a single institution were studied. Retrospectively collected data included patient demographics, American Society of Anesthesiologists score, prior episodes of diverticulitis, interval between last attack and operation, operative time, complications, conversion, and recovery period. RESULTS: A total of 120 patients were included; 89 had a primary diagnosis of diverticulitis. Mean interval from acute diverticulitis to operation was 64 days (range, 1 to 240). Median number of episodes of diverticulitis before colectomy was 3 (range, 1 to 10). Ten patients (11%) required conversion from laparoscopic to open colectomy. Neither interval from acute attack to operation nor number of prior episodes of diverticulitis was associated with any significantly increased rate of conversion to open colectomy, complication rate, operative time, or recovery period (P=not significant). CONCLUSIONS: Our study showed no direct relationship between surgical timing after acute diverticulitis and complication or conversion rates after elective laparoscopic sigmoid colectomy.

[Increase in costs attributable to surgical infection after appendicectomy and colectomy].

OBJECTIVE: To determine the costs, with the help of direct case to case measurement, of the surgical site infection in apendicectomy and colectomy. METHODS DESIGN: cases and controls study, population-based, in which the cases were all the patients diagnosed of surgical site infection after apendicectomy or colectomy in SCIAS- Hospital de Barcelona, and the controls were a random sample of noninfected patients that presented common characteristics for matching purposes. STUDY PERIOD: from January 1, 1998, to December 31, 1999. Types of matching: a) individual, patients grouped according to main diagnosis, main surgical procedure, age and gender, and b) patients grouped according to main diagnosis, main surgical procedure, age and gender using in addition, as controls criteria, the number of secondary diagnoses. DATA SOURCES: computer system with all the registries and clinical histories in electronic support, including the costs registered in real time. ANALYTICAL ACCOUNTING: ADS plus program that calculated the real costs (patient to patient) extracted from real data, such as drugs consumption, medical supplies, additional diagnosis tests and generated stays. The structural costs were imputed in the matrix of costs from the countable calculation and its impact on the direct costs. The cost attributable to the infection was calculated as the additional cost resultant from the difference between cases and controls. STATISTICAL ANALYSIS: the statistical calculations were made by means of the statistical package SPSS, version 9.0. Nonparametric tests were used considering the sample size. The test of Wilcoxon for continuous variables, with the purpose of comparing age, operations length, hospital stay and costs, was applied. The results were expressed as arithmetic mean. A level of statistical meaning of p < 0.01 was considered. RESULTS: The first matching included 23 cases and 23 controls for patients operated on apendicectomy and 20 cases and 20 controls for those operated on colectomy. In matching 2, the sample consisted on 17 pairs of cases and controls on apendicectomy and 14 pairs of cases and controls on colectomy. The infection increased the average length of stay between 7.7 days (matching 1) and 7.3 days (matching 2) in cases of infected apendicectomy and between 17.6 days (matching 1) and 15.4 days (matching 2) in cases of infected colectomy. The patients with apendicectomy infection presented an average cost three times higher than the ones not infected, both in matching 1 (2,998.60 versus 941.89;, respectively; p < 0.0001) and in matching 2 (2,751.70 versus 870.81;, respectively; p < 0.0001). Similar findings were observed in colectomy both in matching 1 (10,705.34 versus 2,600.55;, respectively; p < 0.0001) and in matching 2 (9,081.12 versus 2,621.39;, respectively; p < 0.0001). The average cost of surgical site infection oscillated between 2,056.71; (matching 1) and 1,880.89; (matching 2) in apendicectomy and between 8,140.79; (matching 1) and 6,405.65; (matching 2) in colectomy. CONCLUSIONS: Under the study conditions, the infection of surgical site determines the prolongation of the hospital stay in more than one week in apendicectomy and in more than two in colectomy, with an increase higher than 300% in the total direct cost.

Predicting the need for colectomy in pediatric patients with ulcerative colitis.

Total colectomy is curative for ulcerative colitis. However, many pediatric patients are medically managed and may not require surgery. There are currently no available criteria to identify children who will benefit from early colectomy. The purpose of this review was to identify criteria associated with the need for colectomy. A 15-year review of patients at a major pediatric center with biopsy-proved ulcerative colitis was conducted. Age at the time of the first symptom, diagnosis, and surgery were recorded as well as steroid dependence, site of disease, extraintestinal manifestations, and family history. Seventy-three patients ranging in age from 1 to 18 years were identified. Thirty-seven patients (50.1%) required total colectomy before the age of 18. The average patient age at the time of the first documented symptom was 11.3 +/- 0.5 years. Among patients who were steroid dependent and had pancolitis, 73% required colectomy. Patients with these factors failed medical management 77% (27 of 35) of the time, and colectomy was performed within 3 years of diagnosis. The combination of steroid dependence and pancolitis was associated with an increased need for colectomy. In pediatric patients with these factors, early colectomy may limit the need to endure prolonged courses of medications and the disability allied with this disease.

Benefits of colonoscopic surveillance and prophylactic colectomy in patients with hereditary nonpolyposis colorectal cancer mutations.

BACKGROUND: Predisposition genetic testing is now possible for many hereditary cancer syndromes, including hereditary nonpolyposis colorectal cancer. The optimal management of the elevated risk for cancer in carriers of mutations for hereditary nonpolyposis colorectal cancer is unclear. OBJECTIVE: To assess the life expectancy and quality-adjusted life expectancy benefits derived from endoscopic surveillance and prophylactic colectomy for persons who carry a mutation associated with hereditary nonpolyposis colorectal cancer. DESIGN: Decision analysis model. Lifetime risk for colorectal cancer, efficacy of surveillance and colectomy, stage-specific colorectal cancer mortality, and quality of life were included in the model. SETTING: Decision about a cancer prevention strategy at the time of a positive result on genetic testing. PATIENTS: Carriers of a mutation for hereditary nonpolyposis colorectal cancer who were 25 years of age. INTERVENTIONS: Immediate prophylactic colectomy; delayed colectomy on the basis of age, adenoma, or diagnosis of colorectal cancer; and endoscopic surveillance. Prophylactic surgical options were proctocolectomy with ileoanal anastomosis and subtotal colectomy with ileorectal anastomosis. MEASUREMENTS: Life expectancy and quality-adjusted life expectancy. RESULTS: All risk-reduction strategies led to large gains in life expectancy for carriers of a mutation for hereditary nonpolyposis colorectal cancer, with benefits ranging from 13.5 years for surveillance to 15.6 years for prophylactic proctocolectomy at 25 years of age compared with no intervention. The benefits of colectomy compared with surveillance decreased with increasing age and were minimal if colectomy was performed at the time of colorectal cancer diagnosis. When health-related quality of life was considered, surveillance led to the greatest quality-adjusted life expectancy benefit (3.1 years compared with proctocolectomy and 0.3 years compared with subtotal colectomy). CONCLUSIONS: Colonoscopic surveillance is an effective method of reducing risk for cancer in carriers of a mutation for hereditary nonpolyposis colorectal cancer. The individual patient's choice between prophylactic surgery and surveillance is a complex decision in which personal preferences weigh heavily.

The implications of lighted ureteral stenting in laparoscopic colectomy.

OBJECTIVE: The placement of indwelling ureteral catheters during colorectal surgery has been recommended for prevention of ureteral injuries. With the advent of laparoscopic colectomy (LCo), the role of preoperative placement of lighted ureteral stents (LUS) has also become commonplace. We sought to evaluate the value of lighted ureteral stent placement in laparoscopic colectomy. METHODS: Sixty-six patients underwent LCo with LUS inserted preoperatively. Stents were removed in the immediate postoperative period. Two surgeons performed all the colectomies; 32 patients were males and 34 were females. Fifty patients underwent sigmoid colectomy, 4 had abdominoperineal resection, 4 had right colectomy, and 1 each had transverse or subtotal colectomy. Eighteen patients had a diagnosis of cancer, 34 had diverticular disease, and 14 had neoplastic polyps. Forty patients had bilateral and 26 had unilateral stent placement. A review of the incidence of ureteral injuries, hematuria, and anuria as the cause of acute renal failure was accomplished, comparing the unilateral and bilateral stented groups. RESULTS: One (1.5%) patient suffered a left ureteral laceration during sigmoid colectomy. This was managed successfully with stent reinsertion. Sixty-five (98.4%) patients had gross hematuria lasting 2.93 days (1 to 6 days). The cost of bilateral stent placement was $1,504.32. A statistically significant difference occurred in the duration of hematuria (days) between patients who had unilateral (2.5 +/- 0.82) and bilateral stent placement (3.37 +/- 1.05), (P < 0.001). Four patients suffered from anuria, 2 required renal support needing hemodialysis for 3 to 6 days, 3 (75%) had bilateral stents, and 1 (25%) had a unilateral stent. CONCLUSIONS: We recommend the placement of lighted ureteral stents as a valuable adjunct to laparoscopic colectomy to safeguard ureteral integrity. Transient hematuria is common but requires no intervention. Reflux anuria occurs infrequently and is reversible.

Hospitalization for acute diverticulitis does not mandate routine elective colectomy.

BACKGROUND: Previous studies suggest that elective colectomy is often required after an episode of acute diverticulitis. HYPOTHESIS: Acute diverticulitis initially treated nonoperatively does not require elective colectomy. DESIGN: Retrospective cohort study. SETTING: Twelve Kaiser Permanente hospitals in Southern California. PATIENTS: Three thousand one hundred sixty-five patients with acute diverticulitis. INTERVENTIONS: Colectomy or nonoperative treatment with or without percutaneous abscess drainage. MAIN OUTCOME MEASURES: Recurrent diverticulitis. RESULTS: Emergency colectomy was performed in 614 patients (19.4%). Nonoperative treatment was initially used in 2551 patients (80.6%). Of these, 185 patients (7.3%) had an elective colectomy and the remaining 2366 patients (92.7%) did not. Factors associated with undergoing elective colectomy compared with nonoperative treatment were younger age of the patient, fewer comorbidities, and percutaneous abscess drainage. Mean follow-up was 8.9 years, with a maximum of 12 years. After nonoperative treatment, 314 patients (13.3%) recurred-222 patients had a single recurrence and 92 patients had a rerecurrence. After adjusting for other variables, older age (hazard ratio, >/=50 years vs <50 years = 0.68; 95% confidence interval, 0.53-0.87) was associated with a lower recurrence, whereas higher comorbidity was associated with higher recurrence. Gender and percutaneous abscess drainage had no influence on recurrence. All 92 rerecurrences were treated nonoperatively. The risk of a rerecurrence (29.3%) was significantly higher than a first recurrence (P<.001). Age, gender, Charlson comorbidity index, and percutaneous abscess drainage did not predict rerecurrence. CONCLUSIONS: Very few patients with acute diverticulitis treated nonoperatively have recurrence. Younger age was associated with recurrence. A first recurrence was the only factor that predicted rerecurrences. The low recurrence rate argues against routine elective colectomy after successful nonoperative management of acute diverticulitis.

Does aggressive medical therapy for acute ulcerative colitis result in a higher incidence of staged colectomy?

BACKGROUND: Colectomy with ileal pouch-anal anastomosis is the operation of choice in patients with medically refractory ulcerative colitis. However, aggressive or prolonged medical treatment may result in the patient's needing an urgent operation in which a staged subtotal colectomy is necessary. OBJECTIVE: Our hypothesis is that the incidence of patients requiring a staged approach has increased, along with an increase in hospital stay and total hospital costs. DESIGN: We examined the medical records of 250 consecutive patients with ulcerative colitis who underwent ileal pouch-anal anastomosis between 1984 and 1993. RESULTS: Simultaneous colectomy and ileal pouch-anal anastomosis were performed in 196 patients (78%), while 54 patients (21.6%) required staged subtotal (78%) or partial colectomy (22%). Indications for initial colectomy included failure of medical therapy (42 patients [77.8%]), undifferentiated colitis (five patients [9.3%]), and perforation (six patients [11.1%]). An increase in the incidence of patients requiring staged colectomy during this period was observed (P < .05). Staged procedures led to a prolonged hospital course at a significantly greater total cost. CONCLUSION: We conclude that aggressive medical therapy of acute ulcerative colitis has increased the incidence of urgent staged colectomy with a resulting increase in morbidity, hospital stay, and cost and a less-optimal functional result.

Curative resection for left colonic carcinoma: hemicolectomy vs. segmental colectomy. A prospective, controlled, multicenter trial. French Association for Surgical Research.

PURPOSE: This study was developed to compare median and actuarial survival after left hemicolectomy vs. left segmental colectomy. METHODS: Between January 1980 and January 1985, 270 consecutive patients (133 males and 137 females; mean age, 64 +/- 12 (range, 18-91) years with left colonic carcinoma located between the left third of the transverse colon and (but not, including) the colorectal juncture were randomly allotted to undergo either left hemicolectomy or left segmental colectomy. Left hemicolectomy removed the entire left colon along with the origin of the inferior mesenteric artery and the dependent lymphatic territory. Left segmental colectomy removed a more restricted segment of the colon and left the origin of the inferior mesenteric artery unmolested. RESULTS: After elimination of 10 patients for protocol violation, 131 patients with left hemicolectomy and 129 with left segmental colectomy were analyzed. Both groups were similar with regard to preoperative risk factors (age, sex, obesity, weight loss, anemia, diabetes, cirrhosis, kidney failure, steroid therapy or radiation therapy performed for any cause other than cancer), pathology findings (size, degree of differentiation, Dukes stage, invasion of lymph nodes at the origin of the inferior mesenteric artery), and associated lesions. Only the length of tumor-free margins of colon removed was significantly longer in left hemicolectomy. The number of early postoperative abdominal and extra-abdominal complications was similar in both groups. Overall, early postoperative mortality was 4 percent higher, but not significantly in left hemicolectomy (eight deaths, 6 percent) than in left segmental colectomy (three deaths, 2 percent). Median survival was 10 years and nearly equivalent in both groups. The two actuarial survival curves were similar. Bowel movement frequency was significantly increased after left hemicolectomy during the first postoperative year. Our results suggest that survival after left segmental colectomy is equivalent to that of left hemicolectomy. Notwithstanding the observation of other carcinologic rules, left segmental colectomy rather than left hemicolectomy may theoretically be performed under laparoscopy without compromising the carcinologic outcome.

Comparison between segmental left and extended right colectomies for obstructing left-sided colonic carcinomas.

PURPOSE: This study was designed to compare complications and functions following either radical extended right colectomy without colonic decompression or radical segmental left colectomy with intraoperative decompression for obstructed left-sided colonic carcinomas. METHODS: One hundred three patients with obstructed left-sided colonic carcinoma undergoing primary resection and anastomoses were studied. RESULTS: There were 57 males and 46 females with a median age of 65 (range, 24-98) years and who had a median follow-up of 31 (range, 2-59) months. There were no leaks or intra-abdominal sepsis in the extended right colectomy group (44 patients) compared with one anastomosis leak in the segmental left colectomy (59 patients) group. Median hospital stay was 14 days in both groups, with a range of 8 to 36 days in the segmental left colectomy group and 7 to 44 days in those with extended right resection. One month after surgery, the patients who underwent segmental left colectomy had a median bowel movement of 3 (range, 1-6) per 24 hours compared with those with extended right colectomies who had a median of 5 (2-11) bowel movements per 24 hours. Bowel frequency decreased to four or less episodes per 24 hours in all patients in both groups at six months. CONCLUSION: There was no significant difference between bowel function or complications between the two groups.

Recurrence after colectomy in Crohn's colitis.

PURPOSE: Previous studies on recurrence and reoperation after colectomy in Crohn's colitis have been based on heterogeneous groups of patients, and divergent findings may be explained by referral biases and small numbers of patients. The aim of this study was to account for recurrence rates, present risk factors for recurrence after primary colectomy, and account for the ultimate risk of having a stoma after colectomy with ileorectal anastomosis in patients with Crohn's colitis. METHODS: Data on the primary resection, postoperative recurrence, influence of concomitant risk factors, frequency of stoma operations and proctectomy were evaluated retrospectively using multivariate analysis in a population-based cohort of 833 patients with Crohn's colitis. RESULTS: The cumulative 10-year risk of a symptomatic recurrence was 58 percent (95 percent confidence interval, 53-63 percent) and 47 percent (95 percent confidence interval, 42-52 percent), respectively, after colectomy with ileorectal anastomosis and segmental colonic resection. In colectomy with ileostomy, lower rates were found with respectively 24 percent (95 percent confidence interval, 18-30 percent) and 37 percent (95 percent confidence interval, 32-43 percent) after subtotal colectomy and proctocolectomy with ileostomy. The multivariate analysis showed that perianal disease, ileorectal anastomosis, and segmental resection were independent risk factors for postoperative recurrence. In 76 percent of patients with ileorectal anastomosis, a stoma-free function could be retained during a median follow-up of 12.5 years. CONCLUSION: Colectomy with ileorectal anastomosis or segmental resection is a feasible option in the surgical treatment of Crohn's colitis, although anastomoses, in addition to perianal disease, carry an increased risk of recurrent disease.

The risk of rectal carcinoma following colectomy in ulcerative colitis.

In a series of 1439 patients with ulcerative colitis, managed by one of the authors (E.S.R.H.), surgical resection was performed on 374 patients (26 per cent): colectomy, 273 (subtotal colectomy and mucous fistula, 172, colectomy and primary ileorectal anastomosis, 101); proctocolectomy, 61; and miscellaneous procedures, 40. Of the 172 patients undergoing subtotal colectomy and mucous fistula, 93 (54 per cent) subsequently required rectal excision, 33 (19 per cent) had ileorectal anastomosis performed as a second procedure, and in 46 (27 per cent) the rectum has remained as a mucous fistula. Two hundred seventy-three patients were at risk for the development of rectal cancer after subtotal colectomy; ten patients (3.6 per cent) subsequently developed rectal cancer. The cumulative probability of developing rectal cancer after subtotal colectomy reached 17 per cent at 27 years from disease onset. The tumors were more advanced in stage and of higher grade malignancy than those of a parallel general series of patients with rectal cancer uncomplicated by inflammatory bowel disease. Colectomy and ileorectal anastomosis has been successful for most patients. However, the experience of this series highlights the danger of carcinomatous transformation in the retained rectum, the requirement for regular long-term follow-up, the need for markers of precancerous change, and the value, where relevant, of prophylactic proctectomy.

Hand-assisted laparoscopic colectomy: evolution to a clinically useful technique.

PURPOSE: Hand-assisted laparoscopic colectomy has traversed three phases of distinct development. This review was designed to trace the evolution of hand-assisted colectomy from an infrequently used technique to a clinically useful surgical approach to diseases of the colon and rectum. METHODS: This review compiles previously reported and published experiences with hand-assisted laparoscopic colectomy. RESULTS: During the first phase of development of hand-assisted laparoscopic colectomy, surgeons explored what could be accomplished by a hand inserted into the abdomen through the specimen extraction site as an adjunct to laparoscopic techniques. Case reports and small trials found that manually assisted laparoscopic techniques permitted more rapid completion of laparoscopic-assisted colectomies. In the second phase, surgeons used early devices that facilitated the insertion of the surgeon's hand into the abdomen and helped to maintain the pneumoperitoneum. Larger series and small, randomized trials indicated a time-saving advantage to hand-assisted techniques and similar short-term outcomes as laparoscopic-assisted colectomies. In the current third phase, surgeons are using a new generation of hand-access devices that extend the options for hand-assisted techniques. These devices, like earlier devices, facilitate hand insertion, protect the wound, act as the retrieval site for the specimen, and serve as the portal for construction of extracorporeal anastomoses. In addition, these new devices can serve as laparoscopic trocar sites. This permits selective use of hand-assisted and laparoscopic-assisted techniques at various times in the same operation. These new devices have not undergone clinical trials, and therefore, a final appraisal must await future publication of outcomes. CONCLUSIONS: Hand-assisted laparoscopic colectomy has evolved into a clinically useful surgical technique. New devices facilitate the performance of these operations and permit the surgeon to switch between hand-assisted and laparoscopic techniques.

Urgent subtotal colectomy for severe inflammatory bowel disease.

PURPOSE: The purpose of this study was to assess the safety of subtotal colectomy and outcomes after this procedure in the modern era of immunosuppressive agents and primary pelvic pouch surgery. METHODS: All patients undergoing subtotal colectomy with ileostomy for ulcerative colitis or Crohn's colitis from July 1, 1990 to June 30, 2003 were identified from a prospective database. Only patients who were operated on while hospitalized for disease exacerbation were included in the analysis. Age at colectomy, preoperative days in the hospital, postoperative length of stay, and complications were recorded. The medical records were then reviewed for duration of disease, preoperative diagnosis, use of steroids and immunomodulators, parenteral nutrition, endoscopy findings, albumin level, postoperative diagnosis, and ultimate disposition. RESULTS: One hundred one patients underwent subtotal colectomy for inflammatory bowel disease during the study period. Seventy-four patients met all the inclusion criteria. The mean age was 35.9 (range, 18-86) years. Median duration of disease was 36 (0-240) months, but 28 patients had colitis for less than 1 year, whereas 10 patients had disease of greater than 10 years duration at the time of colectomy. Median preoperative hospital stay was 7 (range, 0-43) days and median postoperative length of stay was 6.5 (range, 4-37) days. Sixty-six patients underwent surgery for refractory exacerbation, 5 for free perforation, 2 for abscess, and 1 patient for hemorrhage. Twenty-seven patients (36.5 percent) had a change in diagnosis after surgery. Complications occurred in 17 patients (23 percent), including 8 cases of central venous catheter-associated thrombosis; 7 of these occurred in patients who had been hospitalized for more than a week before surgery. In the ulcerative colitis patients, 31 of 52 ultimately underwent ileal pouch-anal anastomosis, but 20 (39 percent) chose either completion proctectomy or no further surgery. CONCLUSIONS: Subtotal colectomy with ileostomy remains a safe and effective treatment for patients requiring urgent surgery for severe inflammatory bowel disease. Because of the substantial incidence of change in diagnosis and satisfaction in many patients with an ileostomy, subtotal colectomy with ileostomy may be preferable to primary ileal pouch-anal anastomosis, even when a pouch is considered safe.

A critical analysis of laparoscopic colectomy at a single institution: lessons learned after 1000 cases.

BACKGROUND: A critical outcome analysis of a large, single-institution experience provides a better frame of reference for an assessment of the role of laparoscopic colectomy for colorectal pathology. METHODS: Review of a prospectively gathered database was performed of a consecutive series of laparoscopic colectomy patients who were operated on by 2 surgeons at a single institution (tertiary referral center) using standardized techniques and care plans. Patients were assessed for operative indications, type of resection, operative time, conversion, complications, duration of stay, and readmission within 30 days. RESULTS: One thousand consecutive patients undergoing laparoscopic colectomy from January 1999 thru June 2004 were analyzed. The types of resections were right colectomy = 314, left/sigmoid colectomy/anterior resection = 435, total colectomy = 61, total proctocolectomy = 14, and other = 176. The indications for surgery were diverticular disease = 285, colorectal neoplasia = 285, inflammatory bowel disease = 172, rectal prolapse = 81, and other = 177. The conversion rate was 11.4%. The mean operative time was 112 +/- 45 minutes for all resections. The mean duration of hospitalization for all patients was 3.7 +/- 3.8. The overall complication rate was 9.9%, with the most frequent complications being ileus 2.8%, pulmonary 1.6%, cardiac 1.4%, and wound infection 2.6%. The 30-day readmission rate was 9.1%, and the most frequent reasons for readmission were ileus/small-bowel obstruction, intra-abdominal infection, and anastomotic leak. CONCLUSIONS: This largest single-institution experience with laparoscopic colectomy confirms the benefits of a standardized approach including shorter hospital rehabilitation and low rates of cardiopulmonary and wound complications. Efforts must be directed at improving access to training in laparoscopic colectomy techniques so that patients can benefit from this new technology.
