Gallbladder carcinoma in the era of laparoscopic cholecystectomy.

OBJECTIVE: To assess the usefulness of laparoscopic cholecystectomy for unsuspected and suspected gallbladder carcinoma. DESIGN: Retrospective review with a mean follow-up of 27 months, ranging from 1 to 47 months. SETTING: University hospital and 8 affiliated hospitals. PATIENTS: Of 2616 laparoscopic cholecystectomies performed over 4 years, 24 gallbladder carcinomas were treated by laparoscopic cholecystectomy and retrospectively reviewed. RESULTS: The clinical course depended on the histopathologic depth of invasion of gallbladder carcinoma. All 6 cases of pathologic tumor (pT) stage in situ (pTis) gallbladder carcinoma and 2 cases of pT1 gallbladder carcinoma showed no invasion to the lymphatic, venous, or perineural spaces, and these 8 patients were all doing well from 2 to 19 months (mean, 11 months) after laparoscopic cholecystectomy. Sixteen cases of pT2 or pT3 gallbladder carcinoma invaded the subserosal layer or the liver, and 5 of the 16 patients were dead of liver dysfunction, abdominal wound recurrence, or liver metastasis 5 days and 7, 12, 15, and 18 months after operation, although additional resection of the liver bed with lymph node dissection was performed after laparoscopic cholecystectomy in 4 of these 5 patients. Abdominal wall recurrence in the absence of distant metastasis was present in 3 (19%) of the 16 patients with pT2 or pT3 gallbladder carcinoma due to inoculation of cancer cells in the abdominal stab wounds where the gallbladder or laparoscope was removed. CONCLUSIONS: Gallbladder carcinoma at the pTis or pT1 stage removed laparoscopically needs no other treatment. We recommend that the gallbladder be removed by vinyl bag and port sites be excised or washed with normal saline to prevent port site recurrence in patients with laparoscopic cholecystectomy for pT2 or pT3 carcinoma.

Controlled clinical trial comparing early with interval cholecystectomy for acute cholecystitis.

The traditional management of acute cholecystitis is initial conservative treatment with antibiotics followed by elective cholecystectomy. Although early cholecystectomy has often been advocated, there has been only one randomized controlled clinical trial comparing the two methods of treatment. This paper reports the preliminary results of such a trial in which 32 patients have been studied so far. Of the 17 patients managed conservatively, there was a misdiagnosis in 2 (11-8 per cent). In the remaining 15 patients with acute cholecystitis 3 (20 per cent) required urgent operation because of failure of medical treatment. Elective cholecystectomy was not technically difficult. Of the 15 patients treated by early cholecystectomy, there was a misdiagnosis in 1 (6-8 per cent). Surgery was technically difficult in 2 patients but cholecystectomy was possible in all. The former 2 patients required blood transfusion, but in the remainder the estimated blood loss was only slightly more than in the elective group. There was no mortality in either group nor any complication directly attributable to the biliary surgery. The incidence of minor postoperative complications was only slightly greater in those treated by early operation. The length of postoperative stay was similar in both groups but those treated conservatively spent an average of 11 more days in hospital. The preliminary results indicate that those treated by early cholecystectomy spend less time in hospital and avoid the complications of failed conservative treatment without the added risk of increased postoperative mortality and major complications.

Urgent and early cholecystectomy for acute gallbladder disease.

A retrospective study of 645 cholecystectomies performed in a surgical unit over a 10-year period is presented, of which 236 were carried out during an acute admission. Of these 236 cholecystectomies, 195 were performed for acute cholecystitis and 41 for acute gallstone pancreatitis. In the acute cholecystitis group the proportion of patients over 70 years of age was significantly higher (35 per cent) than the corresponding elective group (10.3 per cent). Of those patients presenting with complications (empyema, gangrene, perforation, and biliary peritonitis) 51 per cent were over the age of 70 years. The most valuable investigation in the diagnosis of acute cholecystitis was ultrasound carried out within the first 48 h, with positive results in 83 per cent of those examined. The mortality for elective cholecystectomy was 0.5 per cent rising to 4.7 per cent in the urgent/early cholecystectomy group. The mean age of the 11 patients who died was 76 years, 8 of these patients being over the age of 70 years. The mortality in the subgroup of patients over 70 years was 10 per cent rising to 20 per cent in the over-80 age group. There were no deaths in the acute gallstone pancreatitis group. We conclude that emergency or early cholecystectomy is a safe procedure in patients under 70 years of age. However, patients over 70 years present with more serious complications of acute gallbladder disease which necessitate urgent surgery. We therefore recommend early cholecystectomy in patients over 70 years despite the high attendant mortality.

Ursodeoxycholic acid exerts no beneficial effect in patients with symptomatic gallstones awaiting cholecystectomy.

Ursodeoxycholic acid (UDCA) and impaired gallbladder motility purportedly reduce biliary pain and acute cholecystitis in patients with gallstones. However, the effect of UDCA in this setting has not been studied prospectively. This issue is important, as in several countries (including the Netherlands) scheduling problems result in long waiting periods for elective cholecystectomy. We conducted a randomized, double-blind, placebo-controlled trial on effects of UDCA in 177 highly symptomatic patients with gallstones scheduled for cholecystectomy. Patients were stratified for colic number in the preceding year (<3: 32 patients; > or =3: 145 patients). Baseline postprandial gallbladder motility was measured by ultrasound in 126 consenting patients. Twenty-three patients (26%) receiving UDCA and 29 (33%) receiving placebo remained colic-free during the waiting period (89 +/- 4; median [range]: 75[4-365] days) before cholecystectomy (P = .3). Number of colics, non-severe biliary pain, and analgesics intake were comparable. A low number of prior colics was associated with a higher likelihood of remaining colic-free (59% vs. 23%, P < .001), without effects on the risk of complications. In patients evaluated for gallbladder motility, 57% were weak and 43% were strong contractors (minimal gallbladder volume > respectively < or = 6 mL). Likelihood to remain colic-free was comparable in strong and weak contractors (31% vs. 33%). In weak contractors, UDCA decreased likelihood to remain colic-free (21% vs. 47%, P = .02). In the placebo group, 3 preoperative and 2 post-cholecystectomy complications occurred. In contrast, all 4 complications in the UDCA group occurred after cholecystectomy. In conclusion, UDCA does not reduce biliary symptoms in highly symptomatic patients. Early cholecystectomy is warranted in patients with symptomatic gallstones.

Stratification for elective laparoscopic cholecystectomy.

BACKGROUND: In a former retrospective study in our clinic, an improvement in patient care was observed after the introduction of laparoscopic cholecystectomy. The aim of this study was to verify whether this improvement could be maintained or even be further improved. METHODS: Retrospective evaluation of all patients who underwent an elective cholecystectomy due to symptomatic cholelithiasis. We compared the results of 1992, the year of the introduction of laparoscopic cholecystectomy with 1993, the year that laparoscopic cholecystectomy became standard procedure. Also we compared specialized with general surgeons. RESULTS: In comparison with 1992 more elective cholecystectomies were performed in 1993 (162 vs 211). In 1993 there were more primary laparoscopic procedures (86 vs 93%) but due to an increase in conversion rate in 1993 (2.5 vs 10%) the overall number of open procedures remained comparable (17 vs 16%). In 1993 there was an increase in cholecystectomies by general surgeons (56 vs 72%). The general surgeons almost doubled their conversion rate in 1993 (6 vs 13%) while that of the specialized surgeons remained comparable (0 vs 2%). Morbidity and mortality remained comparable between 1992 and 1993 and between specialized and general surgeons. CONCLUSIONS: The quality of patient care has not significantly been altered. An improvement could be made if more laparoscopic operations were performed by specialized surgeons, but this would negatively interfere with the working methods of a general hospital. Therefore we suggest stratification: Certain patients, as high-risk patients, preferably should be operated on by specialized surgeons, while routine operations could be performed by general surgeons.

Optimal timing and indications for cholecystectomy in cardiac transplant patients.

Cardiac transplant is performed with increasing frequency as the treatment for end-stage cardiac disease. Although cholelithiasis is more frequent in both pretransplant and posttransplant patients, no standard management approach exists. Because many such patients are cared for outside the transplant center, it is important that general surgeons develop an appropriate strategy to manage this entity. We present our experience with 11 patients from our institution who underwent cholecystectomy before or after cardiac transplantation. In addition, we have reviewed the 76 reported cases of cholecystectomy performed in precardiac or postcardiac transplant patients from centers throughout the world. Any procedure in this patient group requires critical consideration in regard to the timing and type of procedure. Pretransplant patients are well recognized cardiac risks, and posttransplant immunosuppressed patients are at considerable risk for septic complications. Six patients underwent cholecystectomy prior to heart transplant. Five were performed laparoscopically, one as an open procedure. We also report five laparoscopic cholecystectomies in patients after cardiac transplant. One patient in the pretransplant group died 7 days after surgery from an uncontrollable arrhythmia. There were no hemodynamic or septic complications in either group. Current summated experience (87 cases) indicates that the mortality rate for urgent cholecystectomy in the posttransplant group is at least 36%. Because the first presentation of gallstones in this population is often acute cholecystitis, asymptomatic calculi cannot be considered benign. Elective cholecystectomy, laparoscopic or open, is tolerated well both before and after transplant. Given these facts, it seems reasonable to recommend pretransplant screening and posttransplant surveillance for gallstones.(ABSTRACT TRUNCATED AT 250 WORDS)

Extended cholecystectomy for carcinoma of the gallbladder.

We evaluated extended cholecystectomy, wedge resection of the gallbladder bed, and regional lymphadenectomy for carcinoma of the gallbladder. Between 1971 and 1993 we treated 227 patients, 59 of whom were treated with simple cholecystectomy and 66 with extended cholecystectomy. The tumors were classified according to the stages proposed by the Japanese Society of Biliary Surgery. For Stage I and II disease extended cholecystectomy had a better result than simple cholecystectomy. For the extended cholecystectomy cases the cumulative 5-year survival rate was 78.9% for Stage I, 63.6% for Stage II, 44.4% for Stage III, and 8.3% for Stage IV. The survival of Stage I patients was excellent. For cases more advanced than Stage II (S3, N2, Hinf1, and Binf1), the prognosis was significantly worse. In these cases more aggressive surgery may be needed.

Cholecystectomy and carcinoma of the colon. An experimental study.

The influence of cholecystectomy on the development of carcinoma of the colon is investigated. The experimental results show a significantly increased rate of carcinoma of the colon induced by subcutaneous injection of 1,2-Dimethylhydrazin (DMH) in the mouse after cholecystectomy. After 10 weekly injections of 15 mg/kg DMH, 70% of the animals with cholecystectomy developed carcinoma. Only 16% of the mice with similar treatment but without cholecystectomy had carcinoma. The cocarcinogenic effect of cholecystectomy is assumed to be due to the increased production of secondary bile salts by the colonic bacteria and the lacking of the resorptive function of the gallbladder for some carcinogenic substances passing through the liver. The background of this experimental studies are the clinical findings that 10% of patients with carcinoma of the large bowel had previous cholecystectomy.

Laparoscopic cholecystectomy combined with endoscopic sphincterotomy and stone extraction or laparoscopic choledochoscopy and electrohydraulic lithotripsy for management of cholelithiasis with choledocholithiasis.

Six hundred twenty-two laparoscopic cholecystectomies were performed at St. Vincent Hospital over a 14-month period. We reviewed the records of 366 of these patients who were referred to the authors. Thirty-six patients had suspected choledocholithiasis. The primary author (M.E.A.) performed 38 endoscopic retrograde cholangiopancreatography (ERCPs) on these patients for diagnosis and management. Seventeen of the 36 patients had common bile duct stones; 19 patients had negative studies. Of the 17 patients with choledocholithiasis, 15 had successful cannulation of the common bile duct, and, of these, 10 underwent laparoscopic cholecystectomy plus endoscopic sphincterotomy and extraction of the common duct stone(s). In one high-risk elderly patient, we extracted the stone from the common duct and left the gallbladder in situ. Two patients failed endoscopic cannulation and underwent open cholecystectomy with common bile duct exploration. Four additional patients, cannulated successfully, had unsuccessful endoscopic stone removal because the stones were too large or were impacted. Two of these patients underwent open cholecystectomy and common duct exploration. The two other patients underwent laparoscopic cholecystectomy and choledochoscopy through the cystic duct with the flexible choledochoscope. An electrohydraulic lithotripsy probe was then inserted through the choledochoscope to fragment the stones, and stone fragments were allowed to pass through the previously created sphincterotomy. We believe our data, supported by data in the literature, show that these alternative methods for treating choledocholithiasis are safe and effective and should be considered primary modalities for treating this condition now that laparoscopic cholecystectomy is the treatment of choice for cholelithiasis.

Biliary excretion and pharmacokinetics of ceftriaxone after cholecystectomy.

Three groups of patients with biliary tract disease treated by cholecystectomy were given ceftriaxone. In Group 1 single doses of 150 mg and 1500 mg were given on Days 1 and 5 after cholecystectomy. In Group 2 2 g was given daily for 6 days and the cholecystectomy was on Day 2. Patients in Group 3 received 2 g every 12 h for 3 to 5 doses before cholecystectomy. Plasma samples, urine and T-drain bile were collected at various times from Groups 1 and 2 patients. Gallbladder bile and plasma were collected from Group 3 patients at the time of cholecystectomy. The mean (+/- SEM) T-drain bile-to-plasma concentration ratio of ceftriaxone in Groups 1 and 2 was 6.7 +/- 0.92. The mean (+/- SEM) gallbladder bile-to-plasma concentration ratio was 33 +/- 4.2. No clinically significant differences were detected between the kinetics of ceftriaxone in the cholecystectomy patients compared to normal volunteers. The usual dosage of ceftriaxone appeared adequate for prophylaxis or treatment of biliary tract infection by susceptible organisms.

Laparoscopic cholecystectomy for acute cholecystitis.

Because laparoscopic cholecystectomy reduces hospitalization time and postoperative disability, it is being offered to an increasing number of patients with symptomatic gallstones. Nevertheless, acute cholecystitis is still considered by many surgeons to be a relative contraindication. Our standard approach has been to perform laparoscopy on all patients considered candidates for cholecystectomy. From June 1990 to October 1991, the authors personally performed laparoscopic cholecystectomy on 110 patients, 29 (26%) of whom had pathologically confirmed acute cholecystitis. Of these, nine had evidence of gangrene, perforation, or abscess formation. It was necessary to convert to open cholecystectomy in four (14%) patients. In each, inflammation or dense adhesions precluded the performance of a safe operation. The hepatorenal space was drained in 12 (41%) and cystic dust cholangiograms were performed selectively. The mean operating time was 108 min. There were no intraoperative complications. One patient developed a prolonged postoperative paralytic ileus and two patients were noted to have postoperative common duct stones. There were no deaths. The average postoperative stay for laparoscopic cholecystectomy was 2.6 days. We conclude that the advantages of laparoscopic cholecystectomy can be safely and effectively extended to the majority of patients with acute cholecystitis.

Laparoscopic cholecystectomy in pancreas transplant recipients.

Laparoscopic cholecystectomy is the treatment of choice for symptomatic cholelithiasis. Since its introduction in 1987, this procedure has been employed with increasing frequency as its safety has been documented in numerous studies. Absolute contraindications to laparoscopic cholecystectomy have become relative contraindications, and patients previously felt to be at excessive risk for laparoscopic cholecystectomy are viewed as patients who may benefit from laparoscopic cholecystectomy. The use of this procedure in patients with comorbid medical conditions has the potential to decrease patient morbidity. Patients who have previously undergone solid organ transplantation and require immunosuppressive therapy are a group of patients who may benefit from laparoscopic cholecystectomy. We report four patients who have previously undergone combined renal and pancreas transplantation who underwent successful laparoscopic cholecystectomy.

[Cholecystectomy and experimental coloncarcinoma (author's transl)].

The influence of cholecystectomy on the development of carcinoma of the colon is investigated. The experimental results show a significant high rate of carcinoma of the colon induced by subcutaneous injection of 1,2-Dimethylhydrazin (DMH) in the mouse after cholecystectomy. After 10 weekly injections of 15 mg/kg DMH 70% of the animals with cholecystectomy developed carcinoma. Only 16% of the mice with similar treatment but without cholecystectomy had carcinoma. The cocarcinogenic effect of cholecystectomy is assumed to be due to the increased production of secondary bile salts by the colonic bacteria and the lacking of the resorptive function of the gall bladder for some carcinogenic substances passing through the liver. The background of this experimental studies is the clinical findings that 10% of patients with carcinoma of the large bowels had a cholecystectomy previously.

Laparoscopic cholecystectomy: a report of 409 consecutive cases and its future outlook.

A retrospective study was conducted on 409 patients who underwent laparoscopic cholecystectomy at Teikyo University Hospital between May, 1990 and October, 1992. The operation had to be converted to an open cholecystectomy in ten of these patients because of uncontrollable bleeding from the cystic artery in one, venous bleeding due to portal hypertension in one, extensive adhesions of the omentum and the duodenum to the gallbladder in two, extensive adhesions around the gallbladder in four, and extensive adhesions between the gallbladder and the common bile duct (CBD) in two. The time taken to complete the procedure ranged from 30 to 235 min, the average time being 81 min, and the postoperative hospital stay ranged from 3 to 56 days, the average stay being 6.5 days. Eleven patients developed complications intra- or postoperatively: bile duct injury which became manifest after the operation and required laparotomy in three patients; injury to the right hemidiaphragm resulting in a right pneumothorax in one; periumbilical subcutaneous emphysema in one; mild bile leaks which resolved in a few days in two; and a severe bile leak which resolved after 6 days in one. The indications for laparoscopic cholecystectomy have widened with experience and now, CBD stones and a history of previous gastrectomy are no longer contraindications for laparoscopic cholecystectomy. Thus, it seems that laparoscopic cholecystectomy can be performed as safely as a standard cholecystectomy, provided the patients are selected properly and appropriate caution is exercised.

The correlation between cholecystectomy and fecal bile acids, and large-bowel cancer induced with 1,2-dimethylhydrazine in mice.

The relationship between cholecystectomy and large-bowel cancer development was investigated in animal models. Female ICR mice underwent cholecystectomy, and received 15 weekly intragastric administrations (Experiment 1) or 10 weekly subcutaneous injections (Experiment 2) of 15 mg/kg body weight of large-bowel carcinogen 1,2-dimethylhydrazine (DMH). Autopsy at 28 weeks after surgery showed that cholecystectomized mice had a nonsignificantly increased incidence of large-bowel carcinomas, compared to sham-operated and/or unoperated control mice (85 vs. 64 percent in Experiment 1; 31 vs. 16 and 20 percent in Experiment 2). Cholecystectomy alone without DMH treatment did not produce any cancer. Cholecystectomized mice excreted a significantly increased level of primary bile acids but an unchanged level of secondary bile acids in the feces, compared with unoperated control mice. It is obvious that cholecystectomy enhanced the development of DMH-induced, large-bowel carcinomas along with the change of fecal bile acid composition, suggesting that changes of bile acid metabolism after cholecystectomy may enhance or promote large-bowel carcinogenesis in man as well. This association of cholecystectomy and large-bowel cancer is not a strong one, however, as presented in epidemiologic as well as experimental studies.

The absence of a relationship between cholecystectomy and the subsequent occurrence of cancer of the proximal colon.

Reports of an increased incidence of right-sided colonic cancers have coincided with an expanding knowledge of the carcinogenic potential of secondary bile acids which are increased after cholecystectomy, suggesting a possible relationship between cholecystectomy and the subsequent occurrence of proximal colonic cancer. The hospital records of 582 patients undergoing resection of colorectal cancers were reviewed. Fifty-four patients (9 per cent) had had prior cholecystectomies. The distribution of colonic cancers in these patients was identical to that in noncholecystectomized patients. To obtain a prospective view, 249 patients undergoing cholecystectomy between 1958 and 1960 were followed up to 1980. A cancer of the sigmoid colon or rectum occurred in four patients, three to 22 years after cholecystectomy. No patient was readmitted with a carcinoma of the proximal colon. These data fail to support a relationship between cholecystectomy and the subsequent development of a cancer of the cecum or ascending colon.

[Twelve years of laparoscopic cholecystectomy].

UNLABELLED: We studied developments in indication, operation time, conversion rate, morbidity, and mortality from the beginning of laparoscopic cholecystectomy. Between 1990 and 2002 we prospectively evaluated 4498 patients undergoing cholecystectomy (CE), of whom 79% were treated laparoscopically (lap). In 6.6%, the procedure had to be converted from laparoscopic to open cholecystectomy (con), and 14% were performed open from the beginning (open). During the above time period, the rate of open CE decreased steadily (49% in 1990 to 7.2% in 2002). The average operation time of lap CE remained constant with an average of 74 min (range 20-330). The conversion rate decreased in spite of broader indication for lap CE in even more complicated gallstone diseases, from an initial 9.4% to 2.5%. Among intraoperative complications in lap and con, bile duct lesions remained constant with 5/3856 (0.1%), bleeding which led to conversion decreased from 1.9% to 0.3%, and the rate of gall bladder perforation increased from 12% to 20.5%. Thirty-day morbidity was 2% in lap CE, 5% in con, and 11.5% in open. The mortality was 0% in lap, 0.7% in con, and 1% in open. CONCLUSION: Since the introduction of laparoscopic cholecystectomy the indication for this minimal-invasive operation steadily increased, the conversion-rate decreased and the complication-rate could be held low. Even with fast laparoscopic experience 7% of all cholecystectomies are technically difficult and remain to be carried out primarily in an open technique. The laparoscopic cholecystectomy has become the gold standard in the therapy of gallstone disease.

[Postcholecystectomy complaints one year after laparoscopic cholecystectomy. Results of a prospective study of 253 patients].

AIMS: We studied the nature and frequency of symptoms 1 year after laparoscopic cholecystectomy in order to define pre- and perioperative factors that influence the long-term outcome. METHOD: Between September 1994 and August 1995 we prospectively evaluated 268 patients undergoing laparoscopic cholecystectomy using a standard questionnaire. After an average of 16 months (12-25 months) the patients were asked about their symptoms using a similar questionnaire by telephone or were followed up clinically if necessary. RESULTS: In the long-term follow-up the severity of the symptoms according to the Visick score were: Visick I (no symptoms): 164 patients (65%); Visick II: 72 (28%); Visick III: 12 (5%); Visick IV: 5 (2%). The aetiologies of the postcholecystectomy syndrome were: residual stones 1%, subhepatic liquid formation 0.8%, incisional hernia 0.4%, peptic diseases 4%, wound pain 2.4%, functional disorders 26%. Patients with typical or atypical symptoms preoperatively showed no difference in the outcome 1 year after laparoscopic cholecystectomy. Neither did the number and location of laparotomies prior to cholecystectomy or the gallbladder perforation or loss of stones intraoperatively influence the severity of the postcholecystectomy symptoms. CONCLUSIONS: One year after laparoscopic cholecystectomy 93% of the patients have no or only minor abdominal symptoms. Neither the number and location of the laparotomies prior to cholecystectomy nor the loss of gallstones intraoperatively have an impact on the long-term result.
