Long-term follow-up after robotic cholecystectomy.

Most surgeons gain their first clinical experience with surgical robots when performing cholecystectomies. Although this procedure is rather easily applicable for the da Vinci surgical system, the long-term outcome after this operation has not yet been clarified. This study follows up our institutional first series of robotic cholecystectomies (June to November 2001). Patients were assessed on the basis of standardized management including a quality-of-life questionnaire, clinical examination, blood tests, and abdominal sonogram. The follow-up rate for 23 patients after robotic cholecystectomy was 100 per cent and the median follow-up time 33 (30-35) months. There was one (4%) recurrence of gallstone disease in a patient who suffered from solitary choledocholithiasis 29 months after robotic cholecystectomy. Abdominal sonogram, clinical examinations, and blood tests revealed no post-cholecystectomy-specific pathological findings. The main long-term symptoms were bloating (57%), heartburn (43%) and nausea (30%). Of the patients, 96 per cent (22 patients) felt that the operation had cured or significantly improved their specific preoperative symptoms. Long-term results after robotic laparoscopic cholecystectomy are excellent and comparable to those for the conventional laparoscopic procedure. The advanced vision control and instrument maneuverability of robotic surgery might open minimally invasive surgery also for complicated gallstone disease and bile duct surgery.

Dynamic respiratory patterns after laparoscopic cholecystectomy.

Important alterations in respiratory function have been observed after open cholecystectomy. These include a decrease in the abdominal tidal volume, forced vital capacity, and forced expiratory volume at 1 s. Laparoscopic cholecystectomy is a new procedure allowing removal of the gallbladder without a subcostal or midline incision. The result is less postoperative pain and earlier ambulation. This study sought to determine whether changes in rib cage and abdominal wall motion are different after laparoscopic than open cholecystectomy. Twelve otherwise healthy patients underwent respiratory inductive plethysmography prior to and one day after laparoscopic cholecystectomy. Frequency of resting breathing increased 29 percent after laparoscopic cholecystectomy (p = 0.03), while abdominal motion decreased 32 percent (p = 0.03). During coached abdominal breathing, rib cage tidal volume increased 70 percent (p = 0.005) and abdominal tidal volume decreased 29 percent (p = 0.01). These alterations in respiratory pattern after laparoscopic cholecystectomy were smaller in magnitude than those reported following the open procedure.

Prophylactic cholecystectomy with gastric bypass operation: incidence of gallbladder disease.

BACKGROUND: Morbid obesity is one of the major risk factors for gallbladder disease, and this risk is even greater following rapid weight loss. Because of this, prophylactic cholecystectomy has been offered to our patients undergoing the transected silastic ring vertical Roux-en-Y gastric bypass (TSRVRYGBP). A study was undertaken to determine the incidence of pathologic gallbladders in patients undergoing this prophylactic cholecystectomy. METHOD: The records of all patients who underwent TSRVRYGBP from June 1999 through December 2000 were reviewed. Pathologic findings of the gallbladder were documented as cholelithiasis, cholecystitis, cholesterolosis, polyps or normal. RESULTS: 761 patients underwent the operation. 178 patients (23%) had cholecystectomy before the surgery. 154 (20%) had gallstones documented by ultrasound and had cholecystectomy at the time of the surgery. 324 of the 429 patients with negative preoperative findings by ultrasound had pathologic evidence of gallbladder disease. CONCLUSION: Because of the high incidence of gallbladder disease even with negative preoperative findings in morbidly obese patients and the lack of significant morbidity with cholecystectomy in experienced hands, routine cholecystectomy at the time of the weight loss operation is justified.

Simultaneous gastric banding and cholecystectomy in the treatment of morbid obesity: is it feasible?

BACKGROUND: In the last decade, laparoscopic surgery for morbid obesity has become widely employed, including a marked increase in the placement of adjustable gastric bands (AGB). Among the co-morbidities of morbid obesity is cholelithiasis. The question arises whether concomitant cholecystectomy increases the risk of postoperative infectious complications due to the association of a potentially contaminated procedure with a clean operation, placement of an AGB. The aim of this study is to evaluate the postoperative outcome in patients submitted to laparoscopic AGB with cholecystectomy. METHODS: From January 2000 to January 2004, 308 patients (85 men and 223 women) had AGB placed. BMI ranged from 38.9 to 65.6 kg/m(2) (mean 41.6). In 17 patients (5.5%), gallstones were detected by ultrasonography, and cholecystectomy was performed together with the AGB. Mean operative time for placement of the AGB was 58 +/- 18 min, and in those with cholecystectomy 86 +/- 17 min (P =0.20). RESULTS: All patients that had placement of AGB and cholecystectomy had satisfactory postoperative outcome. No infectious complications were observed. CONCLUSION: Laparoscopic cholecystectomy performed simultaneously with placement of an AGB has been a safe procedure.

Is prophylactic cholecystectomy useful in obese patients undergoing gastric bypass?

BACKGROUND: Obesity constitutes a clear risk factor for cholelithiasis, especially if it is associated with a rapid weight loss, as is the case of patients following bariatric surgery. Prophylactic cholecystectomy is indicated in biliopancreatic diversions due to the high incidence of postoperative cholelithiasis. However, there is no agreement on gastric bypass. This study was conducted to establish the incidence of cholecystopathy demonstrated by histology and to assess the indication for prophylactic cholecystectomy in a systematic way on patients undergoing gastric bypass. METHODS: The evaluation is based on 100 consecutive morbidly obese patients undergoing open gastric bypass surgery with concomitant prophylactic cholecystectomy. Variables studied were: age, gender, body mass index, preoperative ultrasound and the anatomopathologic analysis of the gallbladder that was removed. RESULTS: Of the 100 patients who took part in the trial, 11 had had a previous cholecystectomy. Among the 89 patients remaining, preoperative ultrasound diagnosis of cholelithiasis was 16.8%, and the actual postoperative incidence was 24.7%. Other histologic alterations were: cholesterolosis 46.1%, chronic unspecified cholecystitis 22.5%, and granulomatous cholecystitis 1.1%. The total incidence of cholecystopathy was 93.3%. The morbi-mortality related to cholecystectomy was 0%. CONCLUSIONS: Based on these results and given the absence of morbidity, we believe that prophylactic cholecystectomy is suitable during open gastric bypass.

Changing indications for pediatric cholecystectomy.

PURPOSE: The purpose of this study was to determine indications for gallbladder surgery and risk factors for urgent surgery. METHODS: We reviewed all patients <19 years old, who underwent cholecystectomy between 1980 and 1996. RESULTS: There were 128 patients (mean age: 10 years). Fifty-two patients had an underlying hematologic disorder, 47 had another medical disorder, and 29 had no preexisting illness or identifiable risk factor for gallstone disease. Twenty-five percent (32/128) of cholecystectomies were performed urgently. Postoperative complications developed in 5 of 32 patients (16%) who underwent emergency surgery and 6 of 96 patients (6%) who underwent elective surgery. There were 3 deaths, all occurring in patients undergoing emergency cholecystectomy (odds ratio: 23). Furthermore, all who died had congenital heart disease (odds ratio: 183), making congenital heart disease an independent risk factor for gallstone-related mortality. CONCLUSIONS: Cholecystectomy is recommended when medically possible for children with underlying medical diseases. Patients with medical disorders that make them a high surgical risk can be followed clinically, realizing that if urgent surgery is necessary, the morbidity is relatively high. Those children with congenital heart disease and gallstones are at a prohibitively high risk for death after urgent cholecystectomy. For these patients, the risk of an elective cholecystectomy may be acceptable when weighed against the high risk of complications from their gallstones.

[Cholecystectomy in the elderly: early results of open versus laparoscopic approach].

UNLABELLED: The rise of elderly population is due to the improvement of life expectancy. The biliary lithiasis is the most common condition requiring intra-abdominal surgery. Half of these patients sustain associated diseases and frequently develops acute and complicated forms of cholelithiasis. Therefore, cholecystectomy is indicated for patients with chronic symptomatic disease. During a long period open cholecystectomy has been practiced, with low complications and mortality rates. Videolaparoscopy has been recently proposed as an option in these cases, however, few studies compared its advantages over open cholecystectomy for elderly patients. OBJECTIVE: To access the early results of the surgical treatment for cholelithiasis in the elderly submitted to an open or laparoscopic cholecystectomy. METHODS: retrospective study with 246 patients > 65 years old, who underwent elective cholecystectomy through a subcostal incision (group I) or laparoscopic approach (group II). We employed Student's t test and Spearman's correlation for statistical analysis, considering p < 0,05 as significant. RESULTS: A hundred and twenty patients were arranged in group I and 126 in group II. Associated diseases were present in 155 cases (63). There were no differences between the groups regarding both the distribution of comorbid conditions. Conversion was evaluated in 10 patients (8.3%). The mean operative time was 133 minutes in group I and 112 minutes in group II (p=0.001). The mean hospital stay in group I was 3,3 days and in group II was 3.2 days p=0.698. Thirteen patients in each group developed complications: group I (10.8%) and group II (10.3%) p=0,896. There was no statistis significance in complication rate related to gender, age, associated diseases and ASA when the both groups were compared. There were two deaths, both in group II, although the mortality rate was not statiscally significant between the groups (p=0.158). CONCLUSION: Both open and laparoscopic cholecystectomy can be practiced in the elderly with low and similar rate of complications.

The relationship between cholecystectomy, unoperated gallstone disease, and colorectal cancer. A necropsy study.

BACKGROUND: There may be an increased risk of colorectal cancer after cholecystectomy, but the literature is not consistent. It is also possible that any risk might be associated with gallstones rather than cholecystectomy. METHODS: In a prospective necropsy study of 8563 cases, all 219 cases of a previous cholecystectomy were pair-matched to subjects with gallstones and to subjects with a normal gallbladder. In a second study all 192 cases of colorectal cancer were pair-matched to cancer-free subjects. RESULTS: The odds ratio (OR) for developing colorectal cancer after cholecystectomy compared with a normal gallbladder was 1.0 (95% confidence interval, 0.30-3.34) and with unoperated gallstones was 0.88 (0.27-2.76). CONCLUSIONS: This study fails to support an association between cholecystectomy or gallstones and colorectal cancer. For those cases of colorectal cancer versus controls, the OR for previous cholecystectomy was 0.70 (0.23-2.04) and for gallstone disease was 0.93 (0.58-1.48).

Changes of gastrointestinal myoelectric activity and bile acid pool size after cholecystectomy in guinea pigs.

AIM: To investigate the bile acid pool size after cholecystectomy whether or not correlated to the gastrointestinal migrating myoelectric complex (MMC) in guinea pigs. METHODS: Gallbladder motilities were assessed before cholecystectomy. Furthermore, we continuously monitored interdigestive gastrointestinal motilities using bipolar electrodes in conscious guinea pigs before and after surgery at 4 wk in standard diet group and high cholesterol diet (cholesterol gallstone) group. Total bile acid pool sizes were measured by isotope dilution method at meantime. RESULTS: After cholecystectomy, there were parallel falls in duration of phase I, II, III and MMC cycle duration but increase in amplitude in the guinea pigs with normal gallbladder function, and in the guinea pigs with cholesterol stones. However, There were not significantly differences. On the other hand, the bile acid pool was definitely small in the GS guinea pigs compared to normal guinea pigs and became slightly smaller after cholecystectomy. Similarly, bile acid in gallbladder bile, fecal bile acid was slightly increased in GS guinea pigs after cholecystectomy, to the same degree as normal. These differences, however, were not significant. CONCLUSION: It is concluded that in the guinea pigs with normal gallbladder function, and in the guinea pigs with cholesterol stones: (1) Cholecystectomy produce a similar but less marked trend in bile acid pool; and (2) MMC are linked to enterohepatic circulation of bile acids, rather than surgery, which is consistent with changes of the bile acid pool size. As a result, gastrointestinal dyskinesia is not involved in occurrence of postcholecystectomy syndrome.

Long-term weight patterns and risk for cholecystectomy in women.

BACKGROUND: Obesity and rapid weight loss in obese persons are known risk factors for gallstones. However, the effect of intentional, long-term, moderate weight changes on the risk for gallstones is unclear. OBJECTIVE: To study long-term weight patterns in a cohort of women and to examine the relation between weight pattern and risk for cholecystectomy. DESIGN: Prospective cohort study. SETTING: 11 U.S. states. PARTICIPANTS: 47,153 female registered nurses who did not undergo cholecystectomy before 1988. MEASUREMENTS: Cholecystectomy between 1988 and 1994 (ascertained by patient self-report). RESULTS: During the exposure period (1972 to 1988), there was evidence of substantial variation in weight due to intentional weight loss during adulthood. Among cohort patients, 54.9% reported weight cycling with at least one episode of intentional weight loss associated with regain. Of the total cohort, 20.1% were light cyclers (5 to 9 lb of weight loss and gain), 18.8% were moderate cyclers (10 to 19 lb of weight loss and gain), and 16.0% were severe cyclers (> or = 20 lb of weight loss and gain). Net weight gain without cycling occurred in 29.3% of women; net weight loss without cycling was the least common pattern (4.6%). Only 11.1% of the cohort maintained weight within 5 lb over the 16-year period. In the study, 1751 women had undergone cholecystectomy between 1988 and 1994. Compared with weight maintainers, the relative risk for cholecystectomy (adjusted for body mass index, age, alcohol intake, fat intake, and smoking) was 1.20 (95% CI, 0.96 to 1.50) among light cyclers, 1.31 among moderate cyclers (CI, 1.05 to 1.64), and 1.68 among severe cyclers (CI, 1.34 to 2.10). CONCLUSION: Weight cycling was highly prevalent in this large cohort of middle-aged women. The risk for cholecystectomy associated with weight cycling was substantial, independent of attained relative body weight.

Missed malignancies during laparoscopic cholecystectomy.

BACKGROUND/AIMS: Laparoscopic cholecystectomy is now the treatment of choice for symptomatic gallstone diseases. However, besides its great benefits, perhaps the most disappointing complication of this operation is missed malignancies. In this study, patients who had missed malignancies that were diagnosed shortly after laparoscopic cholecystectomy were studied. We aim to find out the cause of missed and delayed diagnosis. METHODOLOGY: Between 1991 and June 1997, 9 patients undergoing laparoscopic cholecystectomy, which had been performed elsewhere 2-9 months earlier, and having had missed malignancy were included in this study. A diagnostic survey was collected from the medical records, questionnaires, and a semiological analysis. All laboratory data and physical findings, before and after laparoscopic cholecystectomy, were recorded. Follow-up data were obtained through a telephone questionnaire. RESULTS: Of these 9 patients, 6 had colorectal carcinoma and 3 had pancreas carcinoma. All patients complained of recent atypical pain at the time of laparoscopic cholecystectomy, except for 1 patient who had no symptomatic regression. CONCLUSIONS: It is necessary to make a careful semiological, physical and laboratory analysis of patients with cholelithiasis before especially laparoscopic cholecystectomy. Elderly patients, atypical biliary pain and associated symptoms must draw attention to the possibility malignancy.

Hospital credentialing for laparoscopic cholecystectomy: is stricter better?

OBJECTIVE: Hospital credentialing standards for laparoscopic cholecystectomy were established to improve surgical outcomes, but standards vary by hospital. We hypothesized that more stringent credentialing would result in better outcomes. DESIGN: Univariate and multivariate logistic analyses were performed using a 1996 survey on hospital credentialing practices. Surgical-outcome data were obtained from statewide hospital discharge abstracts and hospital chart reviews. Multivariate logistic analysis was used to calculate the effects of hospital credentialing stringency and nine credentialing practices on operative and postoperative outcomes (including death), controlling for patient and hospital characteristics. SETTING: Short-stay community hospitals performing laparoscopic cholecystectomy. PATIENTS: Statewide hospital discharge data included 1995 inpatient discharges for laparoscopic cholecystectomy. Medical-records review included 843 laparoscopic cholecystectomy patients selected from 14 North Carolina hospitals with widely different credentialing practices. RESULTS: Surgical complications from laparoscopic cholecystectomies appeared unrelated to stringency of the hospital credentialing environment. Important factors predicting complications included hospital volume and other hospital characteristics such as the number of registered nurses per patient day. CONCLUSIONS: Given current levels of training, performance, and credentialing standards, tightening of credentialing practices may not improve patient outcomes for laparoscopic cholecystectomy.

Risk of pancreatic and periampullary cancer following cholecystectomy.

AIMS: Cholecystectomy has been reported by several investigators to increase the risk of pancreatic cancer. The trophic effect on the gland by increased release of cholecystokinin following cholecystectomy and perturbation of the neurohormonal pancreatic regulation, have been suggested as possible contributing factors. However, while several investigators found that this surgical procedure increases the risk, others have not. In an attempt to clarify whether or not patients who have undergone cholecystectomy are at increased risk for developing pancreatic cancer, we evaluated the frequency with which cholelithiasis and this surgical procedure were present in a large number of patients with pancreatic cancer. METHODS: A total of 720 patients with newly diagnosed pancreatic cancer (415 men and 305 women; mean age 62.6 years, range 22 to 79 years) and 720 controls matched for sex, age, social class, and geographic region, were enrolled in the study. All subjects were interviewed personally and in detail about their clinical history. RESULTS: Cholelithiasis was present in 126 patients with pancreatic cancer (17.5%) and in 95 controls (13.2%), constituting a statistically significant association (odds ratio, 1.39; 95% confidence interval, 1.04 to 1.86). However, considering only the patients and controls in whom the diagnosis of cholelithiasis was made for more than one year before cancer diagnosis or interview, the association was no longer significant (odds ratio, 1.04; 95% confidence interval, 0.75 to 1.44). Cholecystectomy had been performed in 93 patients with pancreatic cancer (12.9%) and in 71 controls (9.9%). When all subjects were considered, the odds ratio was mildly, although not significantly, increased (odds ratio, 1.35; 95% confidence interval, 0.97 to 1.87). When only subjects who underwent cholecystectomy one year or more before the cancer diagnosis or interview were considered, the odds ratio fell to unity (odds ratio, 1.00; 95% confidence interval, 0.70 to 1.43). CONCLUSION: This study, one of the largest on this topic, clearly shows that there is no evidence for an association between cholelithiasis, cholecystectomy, and pancreatic cancer.

Palliative percutaneous transhepatic gallbladder drainage of gallbladder empyema before laparoscopic cholecystectomy.

BACKGROUND/AIMS: This study is conducted to evaluate the feasibility of percutaneous transhepatic gallbladder drainage prior to laparoscopic cholecystectomy for the treatment of gallbladder empyema. We also determine the sonographic findings, causative organism, clinical signs and symptoms, laboratory data, associated underlying medical disorders and the complications related to both cholecystostomy and laparoscopic cholecystectomy. METHODOLOGY: One hundred and forty-five cases of gallbladder empyema were included in this study which was composed of 80 males and 65 females, aged 22-94 years with a mean age of 71-years. All patients underwent percutaneous transhepatic gallbladder drainage under ultrasound and fluoroscopic guidance, and laparoscopic cholecystectomy was carried out thereafter. We analyzed the clinical presentations (signs, symptoms, laboratory and ultrasonographic findings, concomitant medical disorders), causative organisms and the complications related to percutaneous cholecystostomy and laparoscopic cholecystectomy. RESULTS: Percutaneous transhepatic gallbladder drainage was performed successfully in all patients within 48 hours after clinical diagnosis of acute cholecystitis. Complications related to percutaneous transhepatic gallbladder drainage were bile leakage after tract dilatation noted in 2 patients (1.4%), and 20 (14%) patients had pain at the puncture site which radiated to the right shoulder during the procedure, but resolved spontaneously within an hour later. On admission, 102 (70%) patients presented as right upper quadrant pain, 39 (27%) as epigastric pain, 90 (62%) as fever, 108 (74%) patients had leukocytosis, and 33 (22.7%) patients were septic. AST and ALT were elevated in 57% and 51% of patients, respectively. Alkaline phosphatase was elevated in 56% of patients, and 34% of those patients had combined common bile duct stones. Gallbladder stones were documented in 135 (93%) patients, while the remaining 10 (7%) cases were acalculous. Five (3.4%) patients had combined gallbladder adenocarcinoma, 7 (4.8%) had liver abscess, while 13 (9%) had biliary pancreatitis. The ultrasonographic findings included gallbladder distension (93%), wall thickening (90%), pericholecystic fluid accumulation (15%), intraluminal sludge or stone (93%) and intraluminal air (13.9%). Bile culture were positive in 83% of the cases and showed gram-negative bacteria in 75%, gram-positive in 30%, anaerobes in 7%, while no growth in the remaining 17% of the cases. The common pathogens were Escherichia coli (57%), Enterococcus (27%), Klebsiella pneumonia (18%), Morganella morganii (7.6%), Pseudomonas aeruginosa (4.1%) and Salmonella (0.7%). The total postoperative complication rate was 17%, which included wound infection, bleeding, subhepatic abscess, cystic duct stump leak, common bile duct injury and pneumonia. Postoperative mortality was 2.6%. Conversion rate to open cholecystectomy was 27%. Clinical conditions improved within 48 hours after cholecystostomy in 93% of patients. Time interval between cholecystostomy and elective cholecystectomy was 2-21 days with a mean of 4 days. Total hospital stay was 5-38 days (mean: 11 days). CONCLUSIONS: Percutaneous transhepatic gallbladder drainage is a safe and effective procedure for the initial management of gallbladder empyema. We highly recommend this preoperative drainage procedure in patient with sepsis, and for those high-risk patients such as old age and with underlying medical illnesses. This procedure can stabilized the patient so that an appropriate therapeutic planning can be achieved.

Diagnostic workup before laparoscopic cholecystectomy--which diagnostic tools should be used?

BACKGROUND/AIMS: A prerequisite for successful laparoscopic cholecystectomy is the exclusion of potential risks such as cholangiolithiasis, anatomical malformations or diseases of the stomach. As there is no general agreement regarding the appropriate preoperative diagnostic workup, we compared different diagnostic methods as to their value in detecting unknown accompanying diseases and complications. METHODOLOGY: Between 9/90 and 8/93, we performed 850 laparoscopic cholecystectomies. The first 700 were included in this study. A prospective comparison was carried out of the diagnostic accuracy of history, physical examination, laboratory tests, upper gastrointestinal endoscopy or barium meal, i.v. cholangiography and abdominal ultrasound. RESULTS: Measurement of the diameter of the common bile duct was found to be a good noninvasive method for diagnosing common bile duct stones (sensitivity 80%, specificity 99%). In combination with the history and the laboratory tests the sensitivity could be improved to 99%. The sensitivity of i.v. cholangiography in detecting common bile duct stones was 80%, the specificity 99.3%. 646/700 patients underwent preoperative endoscopy/barium meal. In 53 (8.2%) patients pathological findings were found, but only in 4 cases (0.6%) they influenced the indication for laparoscopic cholecystectomy. In 1 patient an advanced gastric cancer was diagnosed 6 months after laparoscopic cholecystectomy, the preoperative barium meal did not show any pathological findings. CONCLUSIONS: The results show that routine ultrasonography in combination with history and laboratory tests prior to laparoscopic cholecystectomy can be recommended for detecting common bile duct stones. In patients with 1 or more pathologic finding endoscopic retrograde cholangiopancreatography should be performed preoperatively. A gastroscopy should be done in patients with nonspecific upper abdominal pain, history of peptic ulcer disease and persisting pain after laparoscopic cholecystectomy.

Delay in treatment of biliary disease during pregnancy increases morbidity and can be avoided with safe laparoscopic cholecystectomy.

Recent reports indicate that laparoscopic cholecystectomy in pregnancy is safe. The aim of this study was to evaluate whether delays in definitive treatment of symptomatic cholelithiasis increase morbidity. We reviewed the records of 16 women who underwent laparoscopic cholecystectomy during pregnancy between 1992 and 1999. Mean age was 24 +/- 5 years (mean +/- standard error). Symptom onset was during the first trimester in nine patients, second trimester in six patients, and third trimester in one patient. Patients had abdominal pain (93%), nausea (93%), emesis (80%), and fever (66%) for a median of 45 days (range 1-195 days) before cholecystectomy. Nine of 11 women who underwent cholecystectomy more than 5 weeks after onset of symptoms experienced recurrent attacks necessitating 15 hospital admissions and four emergency room visits. Moreover four women who developed symptoms in the first and second trimesters but whose operations were delayed to the third trimester had 11 hospital admissions and four emergency room visits; three of those four (75%) women developed premature contractions necessitating tocolytics. Cholecystectomy was completed laparoscopically in 14 women. There was no hospital infant or maternal mortality or morbidity. We recommend prompt laparoscopic cholecystectomy in pregnant women with symptomatic biliary disease because it is safe and it reduces hospital admissions and frequency of premature labor.

Cirrhosis and laparoscopic cholecystectomy.

Although cirrhosis has been regarded as a contraindication to laparoscopic cholecystectomy, there is increasing evidence that patients with mild to moderate cirrhosis may safely undergo laparoscopic cholecystectomy with results superior to those of open cholecystectomy. A prospective evaluation and comparison of outcome in 25 consecutive patients with cirrhosis and 1275 patients without cirrhosis undergoing laparoscopic cholecystectomy was undertaken. Fourteen patients with Child's A cirrhosis, nine with Child's B, and two with Child's C underwent laparoscopic cholecystectomy. After surgery, one patient with Child's C cirrhosis died. The median length of stay was 4 days. Postoperative morbidity occurred in 52% of patients and included hemorrhage (8%), thromboembolism (4%), wound complications (24%), intraabdominal collections (12%), and cardiopulmonary complications (8%). Major comorbidity was present in 60% of patients and contributed to complication rate and prolonged stay. Hemorrhage (P = 0.04) and wound complications (P = 0.02) occurred more frequently in patients with cirrhosis than in patients without cirrhosis. Laparoscopic cholecystectomy in patients with cirrhosis is associated with significant but acceptable morbidity and mortality rates, and complications are frequently related to comorbid conditions.

Hydro-Jet assisted laparroscopic cholecystectomy: initial experience in a porcine model.

BACKGROUND AND OBJECTIVES: Hydro-Jet technology has long been used for cutting various materials like metal and wood in the industrial field. In the medical field, this technology has been applied successfully for selective cutting of the parenchyma of the liver. However, to our knowledge, no data exist on the use of the Hydro-Jet technique for laparoscopic cholecystectomy. The purpose of this study was to evaluate a new dissection technique using a high-pressure water stream (Hydro-Jet) and a new dissection probe for laparoscopic cholecystectomy. METHODS: Thirty pigs underwent laparoscopic cholecystectomy. Pigs were randomized to receive either the conventional or Hydro-Jet assisted dissection technique. The feasibility of this technique and the features of surgical dissection were evaluated and compared between the 2 groups. RESULTS: Laparoscopic cholecystectomy was successful in all animals with no need for conversion to open surgery. The mean operative time was 28 and 36 minutes for Hydro-Jet versus conventional dissection, respectively. Complications using the Hydro-Jet and conventional techniques included 6% and 20% gallbladder perforation and 6.5% and 13% liver laceration, respectively. The use of the Hydro-Jet for cholecystectomy had clear technical advantages over conventional dissection. The Hydro-Jet resulted in a selective dissection of fibrous and connective tissue preserving blood vessels for later ligation. Therefore, the dissection was performed in a relatively bloodless field. The ease of dissection using the new bent tipped dissector represents another advantage. Finally, the continuous water flow allowed a clear view for the operator. CONCLUSIONS: This study shows that Hydro-jet dissection represents an excellent alternative to the conventional technique for laparoscopic cholecystectomy. The improved anatomical dissection combined with an almost bloodless operating field secondary to continuous water flow may decrease dissection-related complications.
