Average charges for cholecystectomy open and laparoscopic procedures, 1994.

Claims to Metropolitan Life Insurance Company by group health insureds and their dependents for an open cholecystectomy averaged $16,260 in 1994 versus $12,930 for a laparoscopic cholecystectomy. Laparoscopic procedures accounted for 71.1 percent of the cholecystectomies charged to MetLife in 1994, up slightly from the 70 percent in 1992. The charges for the open procedure varied by almost twofold among the 10 study states with at least 25 open surgeries; similar between-states variation was also evident among the 16 states in which at least 50 laparoscopic surgeries were performed. Florida, Illinois, Louisiana, California and Texas each reported average total charges above the average for both procedures; whereas Ohio and New Jersey reported the lowest total charges for an open cholecystectomy and Ohio and Michigan had the lowest laparoscopic average total charges. Hospital charges accounted for 77 percent of the total charges for an open procedure and for 69 percent of the laparoscopic surgeries. For both forms of surgery this proportion was the lowest in New York (65 and 48 percent, respectively). Length of stay averaged 6.5 days for the open cholecystectomy and 3.1 days for the laparoscopic procedure.

[Is there an age limit for laparoscopic cholecystectomy? Apropos of 61 patients over 85 years of age].

Bilary surgery in the elderly is associated with high morbidity and mortality. The aim of this prospective study was to determine benefits of laparoscopic cholecystectomy in patients over 85 years. From August 1990 to January 1996, 61 patients (50 women, 11 men) aged over 85 years had laparoscopic cholecystectomy. Thirty seven (60.6%) were at high surgical risk (ASA III). In more than 40% of cases complications were present (acute cholecystitis, gallbladder empyema). Nine patients (14.7%) had choledocholithiasis. Ten (16.3%) conversions were necessary, in 5 cases for choledocholithiasis. Overall morbidity was 9.8%: 2 bibary leaks, 1 pneumonia, 1 urinary injection and 1 lymphangitis. There was no mortality. With excellent pre-operative risk evaluation, laparoscopic cholecystectomy is better than laparotomy cholecystectomy. Laparoscopic cholecystectomy has a low morbidity in the elderly and it allows curative treatment of gallstones complicated or not.

[The value of laparoscopic cholecystectomy in the treatment of gallbladder pathologies].

We have prospectively studied all cholecystectomies performed in one year in our clinic in two groups: 190 cases performed laparoscopically and 98 open. We used standardized records and the EPI 5 program on an IBM compatible computer. There were no significant differences between groups regarding weight, sex and proportion of cases with acute cholecystitis. There were however major differences regarding age, type of habitat, ASA score and association with acute pancreatitis, obstructive jaundice and angiocholitis. Conversion of laparoscopic cholecystectomy to open procedure was imposed in 17 cases (not included in statistical analysis) due to technical difficulties (12 cases), haemorrhagic accidents (6 cases), injury of the common bile duct (1 case), stones lost in the abdominal cavity (3 cases), local peritonitis (5 cases). Laparoscopic cholecystectomy lasted a mean of 74 minutes. We encountered 3 specific complications: one CBD injury recognized intraoperatively and managed by Kehr's procedure (one CBD injury in the open cholecystectomy group), one small bowel perforation and one of biloma. Mortality averaged 0.5% in the LC group (one case of late postoperative stroke considered not related to the procedure) and 1% in the open cholecystectomy group. The hospital admission period was significantly reduced in the LC group (5 days vs. 12 days). LC appears as a safe procedure with a low complication rate. Conversion to open procedure is not a complication. Our study recommend LC as the method of choice in the treatment of gallbladder lithiasis.

Does cholecystectomy always resolve biliary disease?

OBJECTIVE: To evaluate long-term effects of cholecystectomy on typical gallstone symptoms and associated digestive syndrome. DESIGN: Clinical prospective study on selected patients. SETTING: First Surgical Clinic--Catania University. SUBJECTS: 143 gallstone patients, divided in highly symptomatic Group 1 (79) and mild symptomatic Group 2 (64), who underwent cholecystectomy during period 1991/92. MAIN OUTCOME MEASURES: 125/143 patients compiled a set questionnaire to detect any subjective postoperative disorders and to evaluate whether they were similar to preoperative symptoms or were new ones. RESULTS: 125/143 patients completed the 12-month follow-up programme, which revealed a 30% (38/125) with postcholecystectomy symptoms and 13.4% (17) with a postcholecystectomy syndrome. Moreover, 10% (13) of the patients reported the same digestive symptoms as before treatment. Statistical analysis confirmed that cholecystectomy was efficacious in curing gallstone related symptoms and digestive disorders in both Groups with a general improvement in clinical picture (p > 0.01). No significant statistical difference in the incidence of postcholecystectomy dyspeptic symptoms was found between the 2 Groups. CONCLUSION: Cholecystectomy is often efficacious in curing both typical gallstone related symptoms and digestive syndrome. Cholecystectomy patterns of failure in curing digestive disorders is unpredictable preoperatively on the basis of clinical features of the disease.

[Results of laparoscopic cholecystectomy for acute cholecystitis in elderly patients].

OBJECTIVES: The aim of this retrospective study was to evaluate the feasibility and the morbidity of laparoscopic cholecystectomy for acute cholecystitis in elderly patients. METHODS: Among 891 consecutive patients who underwent cholecystectomy, 151 had acute cholecystitis. Fifty three patients of > or = 70 years of age (group 1) were compared to 98 younger patients (group 2). Analysis was made in "intention to treat" so directly open cholecystectomies during the same period were also included. RESULTS: Elderly patients had a lower success rate of laparoscopic treatment (52.8% versus 70.4%; p < 0.05). This difference was due to higher rate of directly open cholecystectomy in the elderly (17% versus 2%). There was no difference between both groups in conversion rate to laparotomy (30.2% versus 26.5%). Surgical morbidity was 7.5% in group 1 and 4% in group 2 (NS). General complications were more frequent in the elderly (p < 0.05). Five patients in group 1 (9.4%) died of general complications of which 3 were operated on directly by open cholecystectomy. There was no mortality in group 2. CONCLUSION: Acute cholecystitis in the elderly remains a severe disease in which laparoscopic treatment is only possible in about fifty percent.

Anesthesia related complications of laparoscopic cholecystectomy.

OBJECTIVE: To determine the incidence of intraoperative anesthesia-related complications of laparoscopic cholecystectomy. DESIGN: A descriptive study. PLACE AND DURATION OF STUDY: The study was conducted in Anesthesia Department of Hayat Shaheed Teaching Hospital, Peshawar from April 1995 to April 1996. SUBJECTS AND METHODS: One hundred consecutive patients (ASA I and ASA II) were anesthetized and monitored intraoperatively for detection of complications. The operative findings and data were recorded on a proforma and finally the results were analyzed. RESULTS: One hundred patients with male to female ratio of 1: 8.09 in the age range of 20-80 years (mean 39 years) underwent general anesthesia for laparoscopic cholecystectomy. The duration of operation in 94 laparoscopic cholecystectomy was from 20 to 80 minutes (mean 60.63 minutes ).The incidence of intraoperative hypotension was 9%. Four percent of the patients developed arrhythmias. Increase in end-tidal-carbon dioxide (ETCO2) was observed in 3% of cases. Conversion rate to open cholecystectomy was 6%. Damage to intraabdominal vessels with trocar insertion occurred in 1% of cases. CONCLUSION: Although laparoscopic cholecystectomy has major surgical and anesthetic advantages, there are anesthesia related complications requiring specific anesthetic interventions to improve patients outcome without compromising their safety.

Prophylactic antibiotics for elective laparoscopic cholecystectomy: are they necessary?

HYPOTHESIS: Prophylactic antibiotic treatment in elective laparoscopic cholecystectomy does not lower the already low infection rate associated with this procedure. DESIGN AND SETTING: Prospective double-blind randomized trial at a community-based training hospital. PATIENTS: Four hundred fifty patients undergoing elective laparoscopic cholecystectomy were randomized into 1 of 3 treatment arms: (1) preoperative cefotetan disodium, 1g intravenously; (2) preoperative cefazolin, 1g intravenously; and (3) intravenous placebo. There were no demographic differences between groups in age, smoking history, American Society of Anesthesiologists score, infection risk class, time of antibiotic administration prior to surgery, and type of skin preparation. INTERVENTIONS: Laparoscopic cholecystectomy was attempted in all cases; however, 10 patients required conversion to an open cholecystectomy and they were included in the statistical analysis. Preoperatively, all patients were randomized in a blinded manner and received cefotetan, cefazolin, or placebo intravenously. RESULTS: There were 10 postoperative infections. In the cefotetan group, there were 3 cases of superficial surgical site infections. In the cefazolin group, there were 2 superficial surgical site infections-1 pneumonia and 1 rhinosinusitis. In the placebo group, there were 2 superficial surgical site infections and 1 urinary tract infection. The overall infection rate in this series was 2.4%. Follow-up was performed at routine postoperative visits and by telephone contact. Data were evaluated using the chi2 test and analysis of variance with Duncan post hoc test (P<.05). CONCLUSION: Based on our data, use of prophylactic antibiotics does not decrease the rate of wound infections in elective laparoscopic cholecystectomy.

The need for antibiotic prophylaxis in elective laparoscopic cholecystectomy: a prospective randomized study.

HYPOTHESIS: The need for antibiotic treatment when performing elective laparoscopic cholecystectomy may not be as important as it is thought. This study assesses the real efficacy of antibiotic prophylaxis in elective laparoscopic cholecystectomy with respect to the postoperative infection rate. DESIGN: A prospective randomized study on the routine use of antibiotic prophylaxis in laparoscopic cholecystectomy. SETTING: University teaching hospital, La Sapienza, Italy. PATIENTS: Eighty-four patients randomly placed into 2 groups (A [n = 44] and B [n = 40]) immediately before undergoing laparoscopic cholecystectomy. METHODS: Before anesthesia was administered, group A received intravenously 2 g of cefotaxime sodium diluted in 100 mL of isotonic sodium chloride solution; group B, 10 mL of isotonic sodium chloride solution in 100 mL of saline. A gallbladder bile sample for culture was withdrawn intraoperatively from all patients. In both groups, age, sex, weight, duration of surgery, presence of diabetes, American Society of Anesthesiologists patient classification score, preoperative autologous blood donation, antibiotic administration, intraoperative gallbladder rupture, findings from bile culture positive for bacteria, episodes of colic within 30 days before surgery, length of postoperative hospital stay, and number of septic complications were recorded. All data were correlated by univariate and multivariate analyses with the onset of septic phenomena. RESULTS: In group A, 3 cases of wound infection, 1 case of subhepatic abscess from bile leakage, and 1 case of urinary tract infection were observed; group B, 4 cases of wound infection, 1 case of bronchopneumonia, and 2 cases of urinary tract infection. Comparison of data showed no statistically significant difference between the groups. Findings from bile examination in patients with sepsis complications were positive in 5 patients in group A and in 6 in group B (P = .91). Multivariate analysis showed diabetes mellitus and colic episodes within 30 days before surgery as independent factors significantly associated to the onset of infectious complications. CONCLUSIONS: In elective laparoscopic cholecystectomy, antibiotic treatment did not seem to affect the incidence and severity of infections or the degree of bile contamination.

Robotically assisted laparoscopic cholecystectomy: a pilot study.

HYPOTHESIS: Since the advent of laparoscopic surgery in 1987 and the introduction of robotics into medicine in 1991, medical technology has advanced to robotic applications in performing surgery. In our study, we investigated the feasibility of performing simple laparoscopic maneuvers and laparoscopic cholecystectomy using a robotic surgical system. DESIGN: The study used a ZEUS robotic system (Computer Motion Inc, Goleta, Calif), consisting of 3 interactive robotic arms fixed at the operating table and remotely controlled by the surgeon. After initial training, using a bench model and 3 isolated porcine livers to perform cholecystectomy, 7 female pigs underwent robotically assisted laparoscopic cholecystectomy. The surgeon, seated at the console, manipulated the 3-mm laparoscopic instruments and performed the surgery. RESULTS: Robotically assisted laparoscopic cholecystectomy was accomplished in all 7 pigs, with a mean operative time of 46 minutes (range, 30-62 minutes). There were no complications. The mean time to setup of the robotic system decreased from 30 minutes to 14 minutes. All the robotic maneuvers were performed without any particular difficulties, and the movements were stable, accurate, and reliable, with good control. CONCLUSIONS: Our preliminary experimental study showed that robotically reproduced laparoscopic maneuvers, such as tying, suturing, dissection, clipping, and cautery, seemed to be as accurate and as fast as maneuvers made without robotics. We conclude that our initial experimental and animal study confirmed the feasibility of robotically assisted laparoscopic cholecystectomy. Further reports are needed to show that robotics can be used for clinical applications in surgery.

Predictive factors for unanticipated admissions after ambulatory laparoscopic cholecystectomy.

HYPOTHESIS: Analysis of the causes of unanticipated admission after ambulatory laparoscopic cholecystectomy may permit the identification of predictive clinical factors for postoperative admission. DESIGN: Univariate and multivariate analyses of clinical variables associated with unplanned admission in a retrospective case-control series of ambulatory laparoscopic cholecystectomies. SETTING: A major university-affiliated teaching hospital. PATIENTS: Seven hundred thirty-one consecutive patients who underwent ambulatory laparoscopic cholecystectomies between January 1, 1996, and December 31, 1999. INTERVENTION: Ambulatory laparoscopic cholecystectomy. MAIN OUTCOME MEASURES: Unplanned postoperative admissions. Univariate and multivariate analyses of 19 clinicopathologic factors were performed to identify independent predictive factors for these admissions. RESULTS: Seven hundred six patients were discharged on the day of operation. The remaining 25 required admission because of pain (n = 10), nausea and vomiting (n = 6), retention of urine (n = 5), patient preference (n = 3), and medical observation (n = 1), giving an unanticipated admission rate of 3.4%. Significant factors associated with unplanned admission included operative duration of longer than 60 minutes and thickened gallbladder wall on ultrasonographic and pathological findings. By means of logistic regression, length of operation was the only independent predictive factor. Operative time exceeding 60 minutes incurred a 4-fold increased risk for unanticipated admission. CONCLUSIONS: Operative duration was the best predictive factor for unplanned admission after ambulatory laparoscopic cholecystectomy. During selection of patients for day surgery, ultrasonographic demonstration of a thickened gallbladder wall should be taken into consideration.

Double-blind, prospective, randomized study of warmed, humidified carbon dioxide insufflation vs standard carbon dioxide for patients undergoing laparoscopic cholecystectomy.

HYPOTHESIS: Patients undergoing warmed, humidified carbon dioxide (CO2) insufflation for laparoscopic cholecystectomy will (1) maintain a warmer intraoperative core temperature, (2) have their surgeon experience less fogging of the camera lens, and (3) have less postoperative pain than patients undergoing laparoscopic cholecystectomy with standard CO2 insufflation. DESIGN: A double-blind, prospective, randomized study comparing patients undergoing laparoscopic cholecystectomy with standard CO2 insufflation vs those receiving warmed, humidified CO2 (Insuflow Filter Heater Hydrator; Lexion Medical, St Paul, Minn) was performed. Main variables included patient core temperature, postoperative pain, analgesic requirements, and camera lens fogging. RESULTS: One hundred one blinded patients (69 women, 32 men) undergoing laparoscopic cholecystectomy were randomized into 2 groups-52 receiving standard CO2 insufflation (group A) and 49 receiving warmed, humidified CO2 (group B). Mean patient intraoperative core temperature change (group A decreased by 0.03 degrees C, group B increased by 0.29 degrees C, P =.01) and mean abdominal pain (Likert scale, 0-10) at 14 days postoperatively (group A, 1.0; group B, 0.3; P =.02) were different. Other variables (camera lens fogging, early postoperative pain, narcotic requirements, recovery room stay, and return to normal activities) between groups were similar. CONCLUSION: While patients undergoing laparoscopic cholecystectomy with warmed, humidified CO2 had several advantages that were statistically significant, no major clinically relevant differences between groups A and B were evident.

Cystic duct cholangiography during laparoscopic cholecystectomy.

At present, there is no consensus regarding the routine use of intraoperative cholangiography during cholecystectomy. We describe a reliable technique for performing cystic duct cholangiography during laparoscopic cholecystectomy. Using this technique, we were able to cannulate the cystic duct in 97% of patients, completely visualize the biliary tree and duodenum in 93% of patients, and identify unsuspected choledocholithiasis in 3% of patients. Treatment options for the management of choledocholithiasis demonstrated by cholangiograms during laparoscopic cholecystectomy include conversion to an open cholecystectomy and common duct exploration, or endoscopic sphincterotomy and common duct stone extraction following laparoscopic cholecystectomy.

Endoscopic cholecystectomy. An analysis of complications.

We analyzed our initial 381 endoscopic cholecystectomies with particular emphasis on postoperative complications. The rate of conversion to open cholecystectomy was 3%. A technical complication occurred in 2% and a non-technical complication in 4%, for a total complication incidence of 6%. There were three postoperative fatalities (0.9%). Two fatal technical complications consisted of unrecognized intestinal injuries at the time of endoscopic cholecystectomy that were obvious when the abdomen was opened. One patient died of a cerebrovascular accident. Nonfatal technical complications included five bile leaks that required treatment. There were no common bile duct injuries, but excessive caution to prevent common bile duct injury may have contributed to the high incidence of bile leaks. Examination of the case numbers of the technical complications and conversion to open cholecystectomy suggests that the learning curve is real and somewhat prolonged, and that a willingness to convert to open cholecystectomy is necessary if technical complications are to be avoided.

Laparoscopic cholecystectomy. The new 'gold standard'?

Laparoscopic cholecystectomy has rapidly been adopted by surgeons, but concerns remain about its safety, the management of common bile duct stones, and the means of appropriate training. Of 647 patients referred for cholecystectomy, preoperative endoscopic retrograde cholangiography was performed in 49 (7.6%), with 27 patients (4%) undergoing sphincterotomy and stone extraction. Traditional cholecystectomy was performed in 29 patients (4.5%). Laparoscopic cholecystectomy was attempted in 618 patients and completed successfully in 600 (97.1%). Surgical trainees functioned as the primary surgeon in 70% of cases. Technical complications occurred in three patients (0.5%), including one patient with a common bile duct laceration (0.2%). Major complications occurred in 10 patients (1.6%), with no perioperative mortality. Mean postoperative hospital stay was 1 day, with return to work or full activity a mean of 8 days after surgery. Two cases of retained common bile duct stones (0.3%) were identified. We now regard laparoscopic cholecystectomy as the "gold standard" therapy for management of symptomatic cholelithiasis.

Malpractice litigation involving laparoscopic cholecystectomy. Cost, cause, and consequences.

OBJECTIVE: To analyze 44 cases of malpractice litigation involving laparoscopic cholecystectomy for cost, cause, and consequences of civil court actions. DESIGN: Survey of national jury verdict reporting services, covering 20 states during the 39-month interval from January 1, 1993, to April 30, 1996. The 44 laparoscopic cholecystectomies were performed during the 40-month interval from February 1, 1989, to June 30, 1992. MAIN OUTCOME MEASURES: Types of injuries leading to litigation, morbidity and mortality from injuries, trial verdicts, and cost of liability payments. RESULTS: The 44 injuries composed 4 main categories of injuries: (1) bile duct, n = 27, 61%; (2) bowel, n = 7, 16%; (3) major vascular, n = 4, 9%; and (4) other, n = 6, 14%. Bowel injuries involved trocar or cautery injury; vascular injuries all involved trocars. There were 7 deaths (16%) overall from either septic peritonitis resulting from bowel injury (4 patients [57%]) or bile peritonitis involving spills or cystic duct leaks (3 patients [43%]). No deaths resulted from injury to main bile ducts. Of the 44 cases, 21 (48%) settled out of court (mean payment, $469,711). Of the remaining 23 cases proceeding to trial, 19 (83%) were defended successfully while 4 (17%) concluded with plaintiff jury verdicts (mean payment, $188,772). CONCLUSIONS: Frequent settlements of cases involving laparoscopic cholecystectomy injuries that are litigated have resulted in a selection of cases of increased defensibility at trial. The high mortality rate from bowel injuries is a new medicolegal finding in laparoscopic cholecystectomies, as expensive to settle (mean payment, $438,000) as laparoscopic cholecystectomy bile duct injury (mean payment, $507,000).

Bile duct injury during cholecystectomy and survival in medicare beneficiaries.

CONTEXT: Common bile duct (CBD) injury during cholecystectomy is a significant source of patient morbidity, but its impact on survival is unclear. OBJECTIVE: To demonstrate the relation between CBD injury and survival and to identify the factors associated with improved survival among Medicare beneficiaries. DESIGN, SETTING, AND PATIENTS: Retrospective study using Medicare National Claims History Part B data (January 1, 1992, through December 31, 1999) linked to death records and to the American Medical Association's (AMA's) Physician Masterfile. Records with a procedure code for cholecystectomy were reviewed and those with an additional procedure code for repair of the CBD within 365 days were defined as having a CBD injury. MAIN OUTCOME MEASURE: Survival after cholecystectomy, controlling for patient (sex, age, comorbidity index, disease severity) and surgeon (procedure year, case order, surgeon specialty) characteristics. RESULTS: Of the 1 570 361 patients identified as having had a cholecystectomy (62.9% women), 7911 patients (0.5%) had CBD injuries. The entire population had a mean (SD) age of 71.4 (10.2) years. Thirty-three percent of all patients died within the 9.2-year follow-up period (median survival, 5.6 years; interquartile range, 3.2-7.4 years), with 55.2% of patients without and 19.5% with a CBD injury remained alive. The adjusted hazard ratio (HR) for death during the follow-up period was significantly higher (2.79; 95% confidence interval [CI]; 2.71-2.88) for patients with a CBD injury than those without CBD injury. The hazard significantly increased with advancing age and comorbidities and decreased with the experience of the repairing surgeon. The adjusted hazard of death during the follow-up period was 11% greater (HR, 1.11; 95% CI, 1.02-1.20) if the repairing surgeon was the same as the injuring surgeon. CONCLUSIONS: The association between CBD injury during cholecystectomy and survival among Medicare beneficiaries is stronger than suggested by previous reports. Referring patients with CBD injuries to surgeons or institutions with greater experience in CBD repair may represent a system-level opportunity to improve outcome.

Endoscopic retrograde cholangiograms of the normal and post-cholecystectomy biliary tree.

The diameter of extrahepatic and intrahepatic bile ducts was measured on 50 normal retrograde cholangiograms and on the cholangiograms of 109 post-cholecystectomy patients undergoing endoscopic retrograde cholangiopancreatography: 70 of the post-cholecystectomy patients had a normal cholangiogram and 39 had retained stone or biliary stricture, of whom 17 were jaundiced. Biliary diameter at all points measured was greater in the post-cholecystectomy patients with no biliary lesion than in normals, and further increased in the presence of pathology (e.g. retained stone). The extent of overlap in biliary diameter between all these three groups is so great that measurement of bile duct calibre cannot separate patients with retained stone from post-cholecystectomy patients without retained stone, or from patients with an entirely normal biliary tree, even in the presence of obstructive jaundice. Methods of evaluating the biliary tract which rely on the measurement of bile duct diameter (e.g. ultrasound) are therefore of limited value in the investigation of post-cholecystectomy patients.

Cholecystokinin (CCK) provocation test: long-term follow-up after cholecystectomy.

Over a 6-year period 264 cholecystokinin (CCK) provocation tests have been performed in 174 patients with undiagnosed right upper quadrant pain. All were carried out by one person (T.W.J.L.) as part of a prospective placebo-controlled crossover study. Following infusion of CCK but not saline, 103 patients developed pain (CCK + ve). These patients were offered cholecystectomy and 90 accepted. Seventy patients developed no pain during either infusion (CCK - ve), and one patient experienced pain with both CCK and saline infusions. Of the 90 patients who underwent cholecystectomy, 81 (90 per cent) have been followed up for a mean of 35 months (range 12 months to 5 1/2 years), 67 per cent have had complete resolution of symptoms and a further 24 per cent have had a marked improvement in symptoms. Only 9 per cent of patients did not benefit from cholecystectomy. This compares well with patients undergoing cholecystectomy for uncomplicated calculous gallbladder disease, 88 per cent of whom, in our study, were improved by surgery. Patients with a positive CCK test have an excellent chance of symptomatic improvement following cholecystectomy.
