Laparoscopic resection of gastrointestinal stromal tumors: not all tumors are created equal.

BACKGROUND: Laparoscopic resection has become an accepted approach to gastrointestinal stromal tumors (GISTs), with acceptable early results published in the literature. Long-term recurrence rates, however, are still unclear, and the management of tumors in challenging locations requires exploration. METHODS: A retrospective analysis of all patients undergoing a laparoscopic resection of gastric GIST in our institution between November 1997 and July 2004 was performed. RESULTS: A total of 14 patients with 15 tumors were evaluated, 5 of which were located high on the lesser curve. All the patients had an attempted laparoscopic approach, with the following procedures performed: stapled wedge excision (n = 8), excision and manual sewing technique (n = 4), and distal gastrectomy (n = 1). Overall, there was a 15% (n = 2) conversion rate. Lesions found in the fundus and greater curvature areas were easily resected via simple stapled wedge excision. High lesser curve tumors were more difficult to manage and required a combination of methods for complete excision and preservation of the gastrointestinal junction including intraoperative gastroscopy, excision and manual sewing technique, and reconstruction over an esophageal bougie. There were no postoperative complications, and the length of hospital stay was 4.6 +/- 1.9 days. At a median follow-up period of 46.5 months (mean, 37.4 +/- 26 months), one patient experienced a recurrence (18 months postoperatively), with eventual disease-related death. CONCLUSION: The laparoscopic approach to gastric GIST tumors is safe and associated with acceptable short- and intermediate-term results. High lesser curve GISTs can be safely approached laparoscopically using various techniques to ensure an adequate resection margin without compromise of the GE junction.

Objective analysis of gastroesophageal reflux after laparoscopic heller myotomy: an anti-reflux procedure is required.

BACKGROUND: Controversy exists over the necessity of performing a concurrent antireflux procedure with a Heller myotomy. We therefore sought to objectively analyze gastroesophageal reflux following laparoscopic Heller myotomy where an antireflux procedure was not performed. METHODS: A prospective database of 66 cases of laparoscopic Heller myotomy performed between November 1996 and June 2002 was reviewed. Previous, concurrent, or subsequent fundoplication was performed in 12 patients; therefore 54 patients without antireflux procedures were available for analysis. Follow-up included symptomatic assessment in 50 patients (93%). Heartburn was assessed on a four-point scale with clinical significance defined as >2 episodes/week. Objective testing, including endoscopy, esophagogram, manometry, and 24-h pH monitoring, was offered to all patients. Objective evidence of reflux was defined as the composite endpoint of positive 24-h pH monitoring or esophagitis on endoscopy. RESULTS: Significant heartburn was reported in 15 of 50 patients (30%). Positive 24-h pH recordings were seen in 11 of 22 patients tested while esophagitis was seen in 13 of 21 patients tested, resulting in objective evidence of reflux in 18 of 30 patients tested (60%). Of these 18 patients, seven did not have significant heartburn. All 12 patients without objective reflux did not have significant heartburn. Therefore, of the 30 patients with objective testing, seven (23%) had objective reflux without subjective heartburn (silent reflux). CONCLUSION: Objective analysis reveals an unacceptable rate of gastroesophageal reflux in laparoscopic Heller myotomy without an antireflux procedure. We therefore recommend performing a concurrent antireflux procedure.

Laparoscopic resections for colorectal cancer: does conversion survival?

BACKGROUND: This purpose of this study was to examine whether survival is affected when laparoscopic resections for colorectal cancer are converted to open surgery. METHODS: A prospective database of 377 consecutive laparoscopic resections for colorectal cancer performed between November 1991 and June 2002 was reviewed. The TNM classification for colorectal cancer and the Kaplan-Meier method were used to determine survival curves for each group. RESULTS: Conversion to an open procedure was required in 46 cases (12.8%). Converted and laparoscopic groups were similar in age, sex, comorbidities, and location and size of tumor. The converted group had a significantly higher weight (75 kg vs 69 kg, p = 0.013) and conversion score (2.18 vs. 1.87, p = 0.005). Patients with stage IV disease were significantly more likely to be converted than those with stage I-III disease (23.0% vs 11.2%, p = 0.04). There was no difference in the conversion rate between patients with stage I (14%), II (8%), or III (13%) colorectal cancers. Median follow-up was 30.5 months for stage I-III and 10.8 months for stage IV cancers. There were 190 patients followed at least 2 years and 73 patients followed at least 5 years. Survival curves demonstrate significantly lower 2-year survival after converted procedures as compared to laparoscopic (75.7% vs 87.2%, p = 0.02), with a trend toward lower 5-year survival (61.9% vs 69.7%, p = 0.077). CONCLUSIONS: Survival rates at 2 and 5 years are lower for patients in the converted group compared to patients with LR. This finding could have serious impact on the treatment of patients with colorectal cancer. Further confirmation is required.

Laparoscopic nephrectomy for autosomal dominant polycystic kidney disease.

BACKGROUND: The authors reviewed their experience with laparoscopic nephrectomy for autosomal dominant polycystic kidney disease to evaluate whether patient-related or surgery-related factors influence operative outcomes. METHODS: A retrospective review was carried out of 22 consecutive laparoscopic nephrectomies performed by one surgeon in a university setting between March 1998 and March 2003. The impact of patient factors (body mass index, preoperative hemoglobin level, preoperative blood urea nitrogen and creatinine, kidney size and side, prior abdominal surgery, dialysis) and surgical factors (surgeon experience and preoperative embolization) on short-term outcomes (estimated blood loss, transfusion requirements, operative time, conversion, intra- and postoperative complications and length of stay) was analyzed using the Student's t-test, Pearson correlation, and Mann-Whitney and Fisher tests. RESULTS: A total of 19 patients underwent 22 nephrectomies. The average patient age was 49 years (range, 36-65 years) and the average body mass index was 31.4 kg/m2 (range, 20.4-64.5 kg/m2). Fourteen patients (68%) were receiving dialysis. Fifteen right (68%) and 7 left (32%) nephrectomies were performed. The median kidney size was 22 cm (range, 8-50 cm). Five patients (23%) had preoperative embolization. The median operative time was 255 min (range, 95-415 min). There were no mortalities. The intraoperative complication rate was 18% (1 vena cava laceration, 1 cecal perforation, 1 dialysis fistula thrombosis, 1 intrarenal bleeding requiring conversion), and the postoperative complication rate was 32% (1 myocardial infarction, 1 urgent laparotomy for clinical peritonitis, 1 minor bile fistula, 1 AV fistula thrombosis, 2 incisional hernias, 1 urinary retention). Four procedures (18%) were converted (1 for vena cava laceration, 1 for cecal perforation, 1 for intrarenal bleeding, 1 for adhesions). The median blood loss was 400 ml (range, 100-5000 ml). Eight patients (36%) received transfusions (median, 2 units). The median length of stay was 4 days. The patients who required blood transfusions had lower preoperative hemoglobin levels. Preoperative embolization did not affect surgical outcome. However, surgeon experience significantly reduced operative time. CONCLUSIONS: Laparoscopic nephrectomy for autosomal dominant polycystic kidney disease is a safe procedure, providing patients with a short hospital stay. Complication and conversion rates are relatively high.

Predicting conversion in laparoscopic colorectal surgery. Fellowship training may be an advantage.

BACKGROUND: Laparoscopic colorectal surgery has clear advantages over open surgery; however, the effectiveness of the approach depends on the conversion rate. The objective of this work was to prospectively validate a model that would predict conversion in laparoscopic colorectal surgery. METHODS: A simple clinical model for predicting conversion in laparoscopic colorectal surgery was previously developed based on a multivariable logistic regression analysis of 367 procedures. This model was applied prospectively to a follow-up group of 248 procedures by the same team, including 54 procedures performed by one new fellowship-trained surgeon. RESULTS: Patients in the follow-up group were more likely to have cancer (56% vs 44%, p = 0.007) and were more obese (median, 71.0 vs 66.0 kg; p < 0.001). The rate of conversion in the follow-up group was unchanged (8.9% vs 9.0%, p > 0.05). Despite expected trends toward increasing risk of conversion with weight level (<60 kg, 6.8%; 60-<90 kg, 9.0%; >90 kg, 12.1%; p > 0.05) and malignancy (10.1% vs 7.3%, p > 0.05), the model did not distinguish well between groups at risk for conversion. Contrary to the model, however, the fellowship-trained surgeon had a conversion rate that was not higher than that of the other, more experienced surgeons (7.3% vs 9.3%, p > 0.05) even though he was less experienced, and operating on patients who were more obese (median, 75.0 vs 70 kg; p = 0.02) and more likely to have cancer (59% vs 55%, p > 0.05). Recalculated conversion scores that excluded the inexperience point for the fellowship-trained surgeon showed a good fit for the model. Considering the original and follow-up experience together (615 cases), the model clearly stratifies patients into low (0 points), medium (1-2 points), and high risk (3-4 points) for conversion, with respective rates of 2.9%, 8.1%, and 20% ( p = 0.001). CONCLUSION: This model appears to be a valid predictor of conversion to open surgery. Fellowship training may provide sufficient experience so that learning curve issues are redundant in early practice. This model now requires validation by other centers.

"Needlescopic" heller myotomy.

MIS continues to evolve with the introduction of new techniques and technology. This report discusses the use of "needlescopic" technology in the surgical management of achalasia. Heller myotomy procedures performed between January 1, 1997, and July 1, 2000, were analyzed and the results of 14 needlescopic procedures were compared with 15 laparoscopic procedures. Demographic and short-term outcome data were compared for each group using chi2, Fisher exact, and Student t tests where appropriate. Both groups were similar in age and gender. However, the needlescopic group weighed less (72.2 vs. 83.5 kg; P = 0.05). Intraoperatively, the needlescopic procedures were shorter (98.2 vs. 131.9 minutes; P = 0.03). There were no conversions to open surgery or differences in the number of intraoperative complications for either group. Postoperatively, the groups had similar complications, time to normal diet, and analgesia requirements. Nonetheless, the needlescopic group had a shorter length of stay in hospital (1.1 vs. 2.0 days; P = 0.04). Needlescopic Heller myotomy appears to be a safe treatment option, resulting in a decreased length of stay and improved wound cosmesis.

Minimally invasive surgery training in Canada: a survey of general surgery.

BACKGROUND: The purpose of this study was to assess the state of surgical training in minimally invasive surgery (MIS) within Canadian academic surgical departments. METHODS: A pretested questionnaire was distributed to the general surgery residents of participating Canadian academic surgical departments. RESULTS: Fourteen of 16 residency programs participated and 235 of 388 residents (60%) responded to the survey. Residents expect to perform both basic (217/235 [92%]) and advanced (123/234 [53%]) MIS procedures on completion of their residency. However, only 41 of 233 (18%) believed that their advanced MIS training would be adequate. On a Likert scale, the most important factors influencing their training included limited advanced case volume (median, 5), limited opportunity in the operating room (OR) (median, 5), lack of attending surgeon interest (median, 4), limited OR time (median, 4), and a lack of surgical department support (median, 4). Residents were concerned about their ability to acquire these skills once they finished their training (median, 4), and 231 of 234 (99%) thought that there was an important role for a MIS surgeon within the academic setting (median, 5). CONCLUSION: The rapid development of MIS has generated complex issues for resident training within the present Canadian academic surgical environment.

Laparoscopic versus open donor nephrectomy.

BACKGROUND: As compared with open donor nephrectomy (OpenDN), laparoscopic donor nephrectomy (LapDN) offers donors more rapid recovery and recipients equivalent graft function, but LapDN costs remain greater. This study compared LapDN and OpenDN with cost-utility analysis. METHODS: Utilities were assessed with time trade-off, probabilities derived from systematic review of the literature and the costs derived from 27 OpenDN and 34 LapDN patients treated contemporaneously. A societal perspective was taken. Lost employment costs were included. An incremental cost-effectiveness ratio (ICER) was calculated with best- and worst-case scenarios for confidence intervals. Sensitivity analyses assessed robustness. RESULTS: LapDN costs are lower (11,170.71 dollars vs 12,631.91 dollars), whereas quality of life (QOL) is superior (0.7247 vs 0.6585 quality-adjusted life years [QALY], rendering LapDN a dominant strategy. The model was robust to all variables, and LapDN remained dominant from a payer perspective. In a worst-case scenario, the ICER for LapDN was at most 2,231.61 dollars per QALY. CONCLUSIONS: LapDN offers improved QOL at lower costs, despite the fact that this analysis included patients treated during the learning curve of LapDN at our institution. By potentially increasing organ donor rates, LapDN may be further cost saving by decreasing the number of patients receiving dialysis.

Health-related quality of life after laparoscopic and open nephrectomy.

BACKGROUND: Postoperative recovery often is assessed with parameters (pain and return to work) susceptible to bias. This study sought objectively to compare postoperative health-related quality of life (HRQL) after laparoscopic and open nephrectomy with the Postoperative Recovery (PRS) (a validated questionnaire designed to assess pain), activities of daily living (ADL), and HRQL in postoperative patients. METHODS: Patients undergoing contemporaneous laparoscopic and open nephrectomy received the PRS pre- and postoperatively. The results were analyzed with analysis of covariance (ANCOV) and survival analysis. RESULTS: The 33 open nephrectomy and 38 laparoscopic patients in this study were comparable in age, gender, body mass index (BMI) and employment. Laparoscopic operative time was longer (p = 0.015), and the hospital stay was shorter (p<0.001). Laparoscopic patients had higher HRQL scores from postoperative days 3 to 365 (p<0.001), and they returned to preoperative HRQL faster (p<0.001). CONCLUSIONS: An objective HRQL instrument confirms that laparoscopic nephrectomy patients recover faster and with a higher HRQL than open surgery patients. The PRS can be modified for use after other abdominal procedures, and may prove useful for comparisons of other minimally invasive surgical techniques.

Laparoscopic splenectomy for idiopathic thrombocytopenic purpura (ITP).

BACKGROUND: Although the short-term benefits of laparoscopic splenectomy (LS) have been well documented, long-term follow-up data of patients who have undergone LS for ITP are scarce. We report our long-term follow-up data in patients who underwent LS for idiopathic thrombocytopenic purpura (ITP). METHODS: Data were obtained from a prospectively collected computer database of 52 patients who underwent LS between October 1992 and December 2000 for medically refractory ITP. Patients and their referring hematologist were contacted, and follow-up information was obtained for 45 patients. RESULTS: Fifty-two patients (27 women and 25 men) underwent LS for ITP. Median operative time was 160 min (range, 70-335); and median blood loss was 100 cc (range, 20-1500). There were seven cases of intraoperative hemorrhage (13.7%), resulting in one conversion. A second case was converted due to inadequate working space in a patient with a 26-cm spleen. Accessory spleens were found in 17 patients (32.7%). Postoperative complications occurred in three patients (5.9%). There were no deaths. Median length of hospital stay was 2 days (range, 1-12). Follow-up data were obtained in 45 patients (86.5%), with a median follow-up of 51 months. Six patients did not respond to surgery initially, and another two patients developed recurrent disease, for a remission rate of 82.2%. Nine patients underwent a damaged red blood cell scan. This group included the two patients who suffered recurrences. A positive scan was obtained in three patients (33%), one of whom was a patient with recurrent disease. This patient underwent an uneventful laparoscopic excision of residual splenic tissue but continues to require intermittent steroids to maintain platelet counts. The two other patients with a positive scan remain in remission. CONCLUSIONS: Laparoscopic splenectomy for ITP is safe and associated with low morbidity and a short hospital stay. Long-term follow-up showed that remission rates of ITP following LS are comparable to those reported in the literature on open surgery.

Laparoscopic splenectomy does the training of minimally invasive surgical fellows affect outcomes?

BACKGROUND: The training of surgeons and residents in laparoscopic surgery has become an important issue. The purpose of this study is to determine if the training of a laparoscopic fellow affects outcomes in patients undergoing laparoscopic splenectomy (LS). METHODS: Data were obtained from a prospectively collected database of patients who underwent LS from August 1994 to November 1999. Outcomes of the last 25 cases, performed by fellows under supervision, were compared to 25 cases performed by staff surgeons prior to the introduction of fellows. RESULTS: Patient demographics, preoperative platelet count, and splenic size were similar for the two groups. Outcome measures comparing the staff and the fellows group including operative time (151 vs 178 min, p = 0.055), blood loss (214 vs 162 ml, p = 0.40), intraoperative complications (3 vs 2, p = 1.0), need for transfusion (2 vs 3, p = 1.0), conversions (1 vs 0, p = 1.0), length of hospital stay (3.3 vs 2.5 days, p = 0.13), and postoperative complications (1 vs 2, p = 1.0) were similar for the two groups. CONCLUSION: When performed by a fellow under supervision, LS has the same outcomes as when the procedure is performed by the teaching staff surgeon.

Local recurrence and survival after laparoscopic mesorectal resection forrectal adenocarcinoma.

BACKGROUND: Laparoscopic resection for rectal cancer is controversial. Actuarial survival and local recurrence rates have not been determined. METHODS: A prospective database containing 80 consecutive unselected laparoscopic resections of rectal cancers performed between November 1991 and 1999 was reviewed. Local recurrence was defined as any detectable local disease at follow-up assessment occurring either alone or in conjunction with generalized recurrence. The tumor node metastases (TNM) classification for colorectal cancers and the Kaplan-Meier method were used to determine staging and survival curves. The mesorectal excision technique was used during surgery. RESULTS: The median follow-up period was 31 months for patients with stages I, II, and III cancer, and 15.5 months for patients with stage IV cancer. The overall 5-year survival rate was 65.1% for all cancer stages and 72.1% for stages I, II, and III cancer. No trocar-site recurrence was observed. The overall local recurrence rate was 3.75% (3/80) for all cancer stages, and 4.3% (3/70) for stages I, II, and III cancer. CONCLUSIONS: The survival and local recurrence rates for patients with rectal cancer treated by laparoscopic mesorectal excision do not differ negatively from those in the literature for open mesorectal excision. Further validation is needed.

"Needlescopic" sigmoid resection.

Minimally invasive surgical techniques and procedures continue to evolve with the trend toward fewer and smaller instruments. To our knowledge, this is the first reported case of sigmoid colon resection utilizing needlescopic technology. The patient was a 53-year-old woman diagnosed with a malignant lesion in the midsigmoid colon at 30 cm. A subsequent needlescopic sigmoid colon resection was performed and the patient was discharged home after an uneventful postoperative course. This case demonstrates that colon procedures that require major reconstruction may be performed needlescopically in selected patients.

Needlescopic fundoplication.

BACKGROUND: Minimally invasive surgery continues to evolve, with an emphasis on developing new techniques and applying new technology to surgical procedures. The purpose of this study was to compare the short-term outcomes of needlescopic fundoplication with those of conventional laparoscopic fundoplication. METHODS: Between January 1999 and June 2000, 38 needlescopic fundoplications were performed, and the short-term outcomes for these patients were compared with those for a contemporary matched cohort of patients who had undergone a conventional laparoscopic fundoplication. RESULTS: There was a nonsignificant trend toward decreased operative time (143.4 to 127 min; p = 0.13), blood loss (54.3 to 48 ml; p = 0.30), narcotic requirements (29.5 to 19.5 morphine equivalents; p = 0.32), and length of hospital stay (1.78 to 1.49 days; p = 0.10) in the needlescopic group. There were no significant differences in intraoperative complications (2.6% vs 2.6%; p = 1.0). Two needlescopic cases were converted to laparoscopic cases because of obesity. Postoperatively, there were no significant differences in rates of early dysphagia (7.9% vs 7.9%), bloating (13.2% vs 5.3%; p = 0.43), or other complications (5.3% vs 5.3%) between the groups. There was a significant reduction in mean operative time for needlescopic fundoplication after the first four cases (166 +/- 44 vs 120 +/- 32 min; p = 0.03). CONCLUSIONS: Needlescopic fundoplication poses no disadvantage, and it offers the added cosmetic benefit of smaller incisions.

Early experience with laparoscopic ileal pouch-anal anastomosis for ulcerative colitis.

The purpose of this study was to describe our minimally invasive technique and outline perioperative and medium-term outcomes in patients undergoing laparoscopic ileal pouch-anal anastomosis (LIPAA) for ulcerative colitis. Data were obtained from a prospectively collected database of 13 LIPPA procedures performed for ulcerative colitis between May 1994 and November 2000. Medium-term quality-of-life follow-up was obtained by telephone interview. Eight males and five females had an LIPAA performed, all of whom had previously undergone total abdominal colectomy with ileostomy. Median operative time was 255 minutes (range, 200-398 minutes) with one conversion (8%) due to adhesions. There were no deaths or intraoperative complications; however, six patients experienced seven postoperative complications within 30 days of final closure of defunctioning ileostomy (two leaks, two wound infections, one pulmonary embolus, and two reoperations for small bowel obstruction). Median length of stay was 7 days (range, 5-13 days). Median follow-up was 24 months (range, 6-66 months). The median number of day and night bowel movements was 6.0 (range, 3-10) and 1.0 (range, 0-3), respectively, with five patients requiring medication to control frequency. None had incontinence of stool or retrograde ejaculation; however, one had occasional incontinence of gas, three had occasional nocturnal soiling, and one was impotent. Three patients (23%) had pouchitis, all treated successfully with oral antibiotics. All patients were satisfied with the outcome of their operation and all preferred their pouch to previous ileostomy. Patients reported their overall social, emotional, and physical well being to be satisfactory to excellent. Results of the SF-36, a generic quality-of-life survey, were similar to those from studies of patients following an open pelvic pouch procedure. The LIPAA is technically feasible in experienced centers. We believe that the technique is still evolving and that more time and experience is required to refine the procedure.

Laparoscopic colorectal resection in octogenarians.

BACKGROUND: The number and proportion of patients aged ?80 years are increasing. These patients often require surgical care and suffer subsequent high rates of morbidity and mortality. However, the surgical outcomes of laparoscopic colorectal resection in octogenarians are not well documented. METHODS: Octogenarians were identified from a large prospective database comprising 507 consecutive laparoscopic colorectal resections performed between 1991 and 1999 in a university setting. Preoperative comorbidity and surgical outcomes were analyzed. RESULTS: Sixty-two patients (30 men, 32 women) aged ?80 years were identified. Their mean age and weight were 85 years and 63 kg, respectively. Seven patients (11%) were converted to an open procedure. Four (6%) intraoperative complications occurred in four patients (one colon perforation, one small bowel perforation, one burned gallbladder serosa, and one missed lesion), necessitating two conversions. Twenty -four postoperative complications occurred in 19 patients (31%) (six ileus [10%], five wound infections [8%], five cardiac problems [8%], two urinary retentions [3%], two hemorrhages [3%], one abscess [2%], one pneumonia [2%], and two other [3%]). Intraoperative complications did not increase postoperative morbidity. Three patients (5%) died within 30 days of surgery. When the procedure was completed laparoscopically, the overall median postoperative hospital stay was 10.0 days; occurrence of a postoperative complication increased the median length of stay to 15.0 days. CONCLUSIONS: These results are superior to published historical controls involving open colorectal resection in octogenarians. Overall mortality, lung, and urinary tract complications were decreased, and there were no reoperations for small bowel obstruction. Laparoscopic colorectal resection is technically feasible and can be done safely in elderly patients. Results require randomization against those for open surgery to elucida te the real advantages of this technique.

Does a laparoscopic approach to total abdominal colectomy and proctocolectomy offer advantages?

BACKGROUND: Controversy exists regarding the feasibility, safety, and outcomes of laparoscopic total abdominal colectomy (LTAC) and laparoscopic total proctocolectomy (LTPC). The object of this study was to assess the outcomes of LTAC and LTPC and compare them with those of institutional open procedure used as controls. METHODS: Perioperative data and surgical outcomes of patients who underwent TAC or TPC were analyzed and compared retrospectively at a single institution between 1991 and 1999. RESULTS: A total of 73 TACs performed during a 9-year period were evenly distributed between laparoscopic (n = 37) and open (n = 36) approaches. There were no significant differences between patient groups with respect to genders, age, weight, proportion of patients with inflammatory bowel disease, and the number of patients undergoing ileorectal anastomosis. The median operative time was longer with the laparoscopic method (270 vs 178 min; p = 0.001), but the median length of hospital stay was significantly shorter (6 vs 9 days; p = 0.001). The short-term postoperative complication rate up to 30 days from surgery was not statistically different (25% vs 44%; p = 0.137), although there was a clear trend toward a reduced number of overall complications in the laparoscopic group (9 vs 24). Wound complications were significantly fewer (0% vs 19%; p = 0.015) and postoperative pneumonia was nonexistent in laparoscopic patients. Long-term complications also were less common in the laparoscopic group (20% vs 64%; p = 0.002), largely because of reduced incidence of impotence, incisional hernia, and ileostomy complications. Total proctocolectomy was performed laparoscopically in 15 patients and with an open procedure in 13 patients over the same period. There were no statistically significant differences between the two groups with respect to gender, age, weight, and diagnosis. Median operating time was longer for the laparoscopic patients (400 vs 235 min; p = 0.001), whereas the length of hospital stay, morbidity, and mortality were not significantly different. CONCLUSIONS: The results indicate that LTAC can be performed safely with a statistically significant reduction in wound and long-term postoperative complications, as compared with its open counterpart. Operating time is increased, but there is a marked reduction in length of hospital stay. Preliminary results demonstrate that LTPC also is technically feasible and safe, with equal morbidity, mortality, and hospital stay, as compared with open procedures. Studies with larger numbers of patients and a randomized controlled trial giving special attention to patient quality-of-life issues are needed to elucidate the real advantages of this minimally invasive technique.
