Lost gallstones during laparoscopic cholecystectomy: are they really benign?

The long-term effect of stones spilled into the peritoneal cavity during laparoscopic cholecystectomy is unknown. The course of a 58-year-old man who had recurrent right subphrenic abscesses and a right empyema secondary to spilled gallstones during laparoscopic cholecystectomy is described. The authors outline techniques for minimizing the spillage of stones during laparoscopic cholecystectomy: the application of hemoclips, endoloops and sutures, and placement of the necrotic, friable gallbladder in an endoscopic bag immediately upon completion of the dissection, before extraction of the gallbladder. They conclude that spillage of stones during laparoscopic cholecystectomy may lead to serious infection and should be recorded in the operative notes so that stones may be suspected when a patient presents with abdominal infection after laparoscopic cholecystectomy.

Diaphragmatic function before and after laparoscopic cholecystectomy.

BACKGROUND: Diaphragm dysfunction is a primary cause of ventilatory impairment after upper abdominal surgery. Laparoscopic procedures may result in less dysfunction. To test this, diaphragmatic function was studied in ten healthy adult patients undergoing elective laparoscopic cholecystectomy and in five undergoing laparoscopic hernia repair. METHODS: Respiratory gas exchange, ventilation, and breathing pattern were measured before and 3 h after surgery. Respiratory drive was evaluated from the relationship of P0.1 to end-tidal carbon dioxide (PETCO2) during tidal breathing. Diaphragm contractile function was assessed from maximal transdiaphragmatic pressure (Pdimax), and Pdi during a maximal sniff maneuver (Pdisniff). RESULTS: Oxygen consumption and carbon dioxide production did not change after surgery. Pdimax decreased by more than 50% in the laparoscopic cholecystectomy group, but Pdisniff did not change. Tidal volume and the ratio of inspiratory time over total cycle time decreased by 30% and 13%, respectively, PETCO2 increased by 9%, and minute ventilation did not change. In contrast, there was no variation in ventilatory function in patients undergoing laparoscopic hernia repair. In both groups, P0.1 did not change, which excludes depressed respiratory drive as an explanation for the decreased Pdimax in laparoscopic cholecystectomy. Contractile failure of the diaphragm was discounted as well, because Pdisniff did not change, even in the laparoscopic cholecystectomy group. CONCLUSIONS: Although laparoscopic cholecystectomy does not increase metabolic demands in the early postoperative period, it impairs diaphragm function. The internal site of surgical intervention appears to be the critical variable determining diaphragmatic inhibition after laparoscopic abdominal surgery.

Laparoscopic cholecystectomy in critically ill cardiac patients.

From August 1989 to January 1993, the authors performed laparoscopic biliary operations in 900 patients, 13 of whom had severe cardiac dysfunction. Nine patients were Goldman Class IV, and four patients were Goldman Class III. Three patients had recent myocardial infarction, five patients were known to have low left ventricular ejection fractions (10%, 21%, 25%, 26%, and 30%), one had severe myocardial ischemia, one had severe congestive heart failure, and one was in profound shock. Nine patients underwent successful laparoscopic cholecystectomy. Laparoscopic cholecystostomies were performed in three patients. One operation was converted to an open cholecystectomy. There was one death within 30 days of surgery. With appropriate hemodynamic monitoring and adequate perioperative support of cardiac function, laparoscopic cholecystectomy can be performed safely for acute cholecystitis in patients with severe cardiac disease. When compared with historical controls, laparoscopic cholecystectomy appears to be safer than open cholecystectomy.

Bile duct injury during laparoscopic cholecystectomy.

OBJECTIVE: To determine the nature of bile duct injuries during laparoscopic cholecystectomy, the treatment of these injuries and patient outcome. DESIGN: Case series review. SETTING: Two tertiary care hospitals. PATIENTS: Twenty-one patients (average age 37 years) who sustained bile duct injuries during laparoscopic cholecystectomy over a 2-year period. Two groups were analysed: patients whose injury was recognized intraoperatively (9 patients) and patients in whom it was diagnosed postoperatively (12 patients). INTERVENTIONS: Laparoscopic cholecystectomy, duct-to-duct repair over a T tube, Roux-en-Y hepaticojejunostomy, endoscopic cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC). RESULTS: Misidentification of the common duct during laparoscopic cholecystectomy, resulting in accidental division or resection of a portion of the duct, and obstruction of the duct by hemoclips were the most common types of injury. Pain, jaundice and bile collections were the typical presenting features of injuries that became evident after laparoscopic cholecystectomy. ERCP and PTC accurately defined the injuries. Immediate duct-to-duct repair over a T tube was associated with a high failure rate. Twenty of the 21 patients required Roux-en-Y hepaticojejunostomy for definitive treatment. There were no deaths. CONCLUSIONS: Proper identification of the pertinent anatomy will prevent the majority of these injuries. Prompt radiographic visualization of the biliary tract is indicated in patients who have pain, jaundice and bile collections postoperatively. A hepaticojejunostomy is the procedure of choice for repair of these bile duct injuries.

Introduction of a "safety zone" for the safety of laparoscopic cholecystectomy.

Anatomic variations of the biliary tract were found in 18 cases of 600 patients (3.0%) undergoing laparoscopic cholecystectomy. All bile duct anomalies were confirmed preoperatively by endoscopic retrograde cholangiography. In every case, the cystic duct and cystic artery were exposed in a "safety zone" near the gallbladder neck in Calot's triangle. Laparoscopic cholecystectomy was successfully performed on all 18 cases. Intraoperative cholangiography clearly demonstrated the anatomic variations in all cases, unequivocally identified the cystic duct, and confirmed the absence of bile duct injury. Preoperative endoscopic retrograde cholangiography and intraoperative cholangiography, which have been performed routinely in all patients, improve the safety of laparoscopic cholecystectomy. Moreover, the observance of the essential rule of "keep operating in the safety zone" protects against inadvertent complications, especially against bile duct injury during laparoscopic cholecystectomy. Laparoscopic cholecystectomy was thus successfully performed on all 600 cases in the present series, except for three cases, which were converted to open surgery (conversion rates, 0.5%), because of pin-hole bleeding on the portal vein in our first case of 600, and severe adhesion in two (46th and 302nd) cases.

Laparoscopic cholecystectomy in pregnancy: contraindicated or indicated?

Laparoscopic cholecystectomy has proven to be superior to traditional open cholecystectomy in uncomplicated cases of cholecystitis. The patients experience less pain with less need for narcotics, fewer incisional complications, earlier postoperative ambulation, and a shorter hospitalization. It is our opinion that pregnancy, previously considered an absolute contraindication to laparoscopic cholecystectomy, is now an indication for laparoscopic cholecystectomy in select patients. We describe one of our cases of laparoscopic cholecystectomy during pregnancy. The patient was at 17 weeks gestation and had an unremarkable procedure and a recovery similar to that expected for a non-pregnant patient. Review of current literature has shown that this procedure can be done safely and with an excellent outcome for both the patient and her fetus.

Routine preoperative infusion cholangiography versus intraoperative cholangiography at elective cholecystectomy: a prospective study in 995 patients.

BACKGROUND: There has been a resurgence of interest in recent years in preoperative infusion cholangiography (PIC). The role of routine PIC compared to routine intraoperative cholangiography (IOC) has not been clearly defined. STUDY DESIGN: In our department between 1985 and 1991, 1,042 of 1,576 consecutive patients with biliary calculous disease had elective cholecystectomy: 694 patients were prospectively scheduled for PIC, and 348 patients were randomly allocated to IOC. The patients in the PIC and IOC groups were similar with regard to age, history of biliopancreatic complications, and laboratory findings. The cost of PIC in Sweden is nearly five times greater than the cost of IOC. RESULTS: Satisfactory opacification of the biliary system was obtained in 90.1 and 96.8 percent of patients who underwent PIC and IOC, respectively. Preoperative infusion cholangiography required support by IOC in 19.5 percent of patients. There were no statistically significant differences between the PIC and IOC groups with regard to the incidence (7 percent in both groups) of or positive predictive value (68 and 80 percent, respectively) for bile duct stones, rate of retained stones (6 and 20 percent, respectively), intraoperative (5.6 and 6.3 percent, respectively) or postoperative (13.3 and 15.9 percent, respectively) morbidity, or incidence of bile duct anomalies (0.9 and 0.3 percent, respectively). Median operative time was longer in patients with (95 minutes) compared to those without (75 minutes) IOC (p < 0.001). More postoperative complications occurred after bile duct exploration (26 of 75 patients) compared to cholecystectomy alone (114 of 917 patients, p < 0.001). The 30-day mortality was zero. Minor bile duct injuries occurred in two patients (0.2 percent) at cholecystectomy, (one with and one without bile duct exploration). In no patient was the cholangiographic finding of a biliary anomaly crucial for the safe execution of cholecystectomy. CONCLUSIONS: In our study, PIC and IOC were comparable, but routine use of either method did not promote the safety of cholecystectomy and thus their routine use is not warranted. The shorter operative time and preoperative identification of common bile duct (CBD) stones provided by PIC might favor this examination when applied selectively in patients with increased risk of having CBD stones. However, this potential advantage is offset by the need for PIC to be supported by IOC in approximately 20 percent of patients. Also, the cost of PIC is greater than the cost of IOC.

[Laparoscopic cholecystectomy for gallbladder stones].

The authors describe the technique for the treatment of gallbladder stones using a laparoscopic approach and discuss the diagnostic and operative flow chart stressing complications and ways to avoid them. A total of 2517 non-selected patients underwent surgery since october 1990 up to september 1995. 252 were affected by acute cholecystitis (10%); 172 underwent emergency laparoscopic cholecystectomy. ERCP was performed in 278 patients (11.04%): 177 underwent endoscopic sphincterotomy and laparoscopic cholecystectomy, 21 underwent laparoscopic cholecystectomy before sphincterotomy, 8 laparoscopic cholecystectomy and ESWL. Laparoscopic cholecystectomy was converted into laparotomy in 37 patients (1.4%); surgery was abandoned in 3 patients following to onset of intense bradycardia. Major complications were observed in 0.63%; bile duct injury occurred in four patients (0.15%). One patient died following a massive intraoperative myocardial infarction. Average operative time was 21 minutes. Only 22.8% of patients required mild analgesia on the first day after surgery. The average hospital postoperative stay was 2.6 days. Return to work took place in 98% of non complicated patients within one week of being discharged from hospital.

[Video-laparoscopic cholecystectomy with suprapubic approach. Technical note].

The authors describe a personal variant of the videolaparoscopic technique of cholecystectomy. This is characterised by the use of an open access to the abdominal cavity following the execution of pneumoperitoneum through an incision in a non-umbilical but suprapubic site, and the use of only three incisions and therefore only three operating trocars. Twenty-nine cholecystectomies have been performed using this personal technique of which only 2 had to be converted to open surgery. The reasons were not attributable to the technique and no complications were observed. The authors also performed a total of 99 laparoscopic cholecystectomies between February 1993 and September 1994 with a total of 4 reconversions and 1 complication (choleperitoneum). Concomitant lithiasis of the choledochus was present in 4 cases and treated with operative ERCP prior to laparoscopic cholecystectomy. Throughout this period only 4 cholecystectomies were performed using a laparotomic access roule owing to concomitant choledochal lithiasis and non-cannulatable papilla during ERCP. The reasons that led the authors to prefer the suprapubic access route were both aesthetic and technical owing to the reduced interference of the videocamera with other instruments, whereas the use of only 3 trocars was also based on the need to economise as well as on aesthetic grounds.

Five years of laparoscopic cholecystectomy in The Netherlands.

Since its introduction in spring 1990, laparoscopic cholecystectomy has become the treatment of choice for uncomplicated gallstone disease in The Netherlands. Several nation-wide surveys conducted by the authors show a rapid diffusion of this operation. 70-75% of all cholecystectomies are performed laparoscopically in almost all Dutch hospitals. The incidence of common bile duct lesions was relatively high at the beginning (1% in 1991) but declined to 0.68% at the end of 1992. It is assumed that the incidence of these lesions will decrease further to a percentage comparable to that after conventional cholecystectomies of 0.5%. The wound related complications of 1.65% is rather low. Despite the reduction in operative morbidity and early resumption of full activity resumption laparoscopic cholecystectomy has met financial restraints, because of the budget system in The Netherlands. There are no incentives for surgeons, hospital management and health insurance companies to stimulate laparoscopic cholecystectomy. The social-economic benefit of the operation is difficult to quantify in the current health care system in The Netherlands.

Complications in laparoscopic and open cholecystectomy: a prospective comparative trial.

Laparoscopic cholecystectomy (n = 250) was compared with the open procedure (n = 250) in a prospective comparative study focusing on complications. Severity grade was classified according to the Toronto system. The frequency of severity grade 1 complications was equal after open and laparoscopic cholecystectomy (5.6%), but major complications (grade 2 and higher) were significantly more frequent in the open group (10.4 versus 3.6%). The only postoperative death occurred after open cholecystectomy. The conventional advantages of laparoscopic cholecystectomy were also verified: The need for postoperative analgesics was significantly reduced from 7 (range, 4-16) standard opiate doses in the open group to 3 (range, 0-7) in the laparoscopic group. Hospital stay was reduced from 6 (range, 4-31) days after open surgery to 2 (range, 1-7) days after laparoscopic surgery and sick leave from 28 (range, 18-48) to 10 (range, 2-21) days, respectively. The overall complication rate was significantly higher in the open group (16 versus 9%, p < 0.01). In our hands, laparoscopic cholecystectomy carries a lower risk of serious complications than the open procedure.

[Management of choledocholithiasis in patients undergoing laparoscopic cholecystectomy].

The development of laparoscopic cholecystectomy has rekindled the issue of management of choledocholithiasis. A number of options exist including pre or postoperative endoscopic sphincterotomy (ERCP-ES), laparoscopic common duct exploration or open common duct exploration. We present here our experience with the management of choledocholithiasis in patients treated with laparoscopic cholecystectomy. From January 1991 to January 1995, 900 patients underwent laparoscopic cholecystectomy. 71 ERCP were carried out in 71 patients with suspicion or evidence of choledocholithiasis. Common duct stones were detected in 44 patients. Preoperative ERCP was done in 56 patients, with suspicion of choledocholithiasis, based on clinical, laboratory or ultrasonographic findings. 29 of these patients (51.7%) had common duct stones, that were successfully removed by endoscopic sphincterotomy. One patient suffered mild pancreatitis and a second one had transient hyperamylasemia. Postoperative ERCP was performed in 15 patients. Indications for ERCP were the evidence of common duct stones in intraoperative cholangiography in 7 cases, and clinical or laboratory suspicion of choledocholithiasis, 3 months to 3 years after laparoscopic cholecystectomy. Stones were detected in 100% of the patients. In 11 patients (73.3%), the stones were extracted by endoscopic sphincterotomy and 4 patients underwent open common duct exploration. Two patients had transient hyperamylasemia. ERCP is a safe and effective method for detection and treatment of common duct stones. ERCP prior to laparoscopic cholecystectomy in patients suspected of having choledocholithiasis, is safe and offers with good results. Rutinary intraoperative cholangiography is recommended, for the detection of unsuspected choledocholithiasis and as an effective treatment (postoperative-ERCP, open or laparoscopic common duct exploration) can be chosen depending on surgeon's skills and patient's characteristics.

Common duct exploration during laparoscopic cholecystectomy.

Management of a common duct stone detected during laparoscopic cholecystectomy remains controversial. Although endoscopic retrograde cholangiopancreatography with sphincterotomy is a procedure preferred by many authors, it has a reported 15 per cent reported morbidity, 1 per cent mortality, 5 per cent failure rate, and 5 per cent incidence of late ampullary stenosis. Cystic duct dilatation with the introduction of a choledoscope and a basket remains an alternative but has a risk of a common duct tear and difficulty in manipulation of instrument should the cystic duct enter the common duct at an angle, and it causes difficulty in extraction of larger stones. In our experience, a choledochotomy with removal of stones during the laparoscopic cholecystectomy is a satisfactory direct approach. We reviewed all of the cholecystectomies performed in the regional hospital since the introduction of the laparoscopic technique. There were 425 cases of laparoscopic cholecystectomies performed with cholangiography, with detection of a stone in 11 patients. In these patients, choledochotomies were performed by making an incision on the anterior surface of the common duct using scissors. The cystic duct should not be divided following cholangiography since provided traction. Following exploration using a Fogarty catheter, a T tube was placed, and a T tube cholangiogram was performed prior to its removal. With this technique, we successfully removed the stones in 10 cases. In one, an impacted stone was removed in the X-Ray Department, 6 weeks postoperative and enables cholecystectomy and bile duct stones to be removed in one session with no increase in morbidity or mortality.

Cholecystectomy in sickle cell anemia patients: perioperative outcome of 364 cases from the National Preoperative Transfusion Study. Preoperative Transfusion in Sickle Cell Disease Study Group.

Cholecystectomy is the most common surgical procedure performed in sickle cell anemia (SCA) patients. We investigated the effects of transfusion and surgical method on perioperative outcome. A total of 364 patients underwent cholecystectomy: group 1 (randomized to aggressive transfusion) 110 patients; group 2 (randomized to conservative transfusion) 120 patients; group 3 (nonrandomized nontransfusion) 37 patients; and group 4 (nonrandomized transfusion) 97 patients. Patients were similar except group 3 patients were more likely to be female, over 20 years old, smokers, and more healthy by American Society of Anesthesiologists (ASA) physical status score. Total complication rate was 39%: sickle cell events 19%; intraoperative or recovery room events 11%; transfusion complications 10%; postoperative surgical events 4%; and death 1%. Group 3 patients had the highest incidence of sickle cell events (32%). Open cholecystectomies were performed in 58% and laparoscopic in 42%. Laparoscopic patients were younger and more healthy by ASA score. Laparoscopic patients had longer anesthesia time (3.2 v 2.9 hours), but shorter hospitalization time (6.4 days v 9.8). Complications were similar between these two groups. We conclude that SCA patients undergoing cholecystectomy have a high perioperative morbidity, and the incidence of sickle cell events may be higher in patients not preoperatively transfused. We recommend a conservative preoperative transfusion regimen, and we encourage the use of the laparoscopic technique for SCA patients undergoing elective cholecystectomy.

[THe video laparoscopic experience of the general surgeon in cholecystectomy in childhood].

Despite the exponentially increasing number of laparoscopic cholecystectomies on adults to date, there is a paucity of reports in the literature about this new technique in pediatric patients. From September 1992 to February 1995, 140 patients underwent laparoscopic cholecystectomy. Since July 1993, in our institution, five pediatric patients (three females and two males) with a diagnosis of cholelithiasis underwent laparoscopic cholecystectomy. The age of the patients ranged from 6 to 15 years (mean 8.8 years) and they weighed 18-58 kg (mean 28.4 kg). All five patients had biliary cholic and ultrasound evidence of cholelithiasis. One patient had associated hematological disease (sickle cell disease). All 5 children were operated using the laparoscopic approach technique. Operative cholangiography was performed in cases with ductal and vascular intraoperative anatomy unclear. No operation was converted to open cholecystectomy. Intraoperative cholangiography was performed successfully (100%). The mean time of surgery was 50.2 minutes (range from 38 to 68). There were no operative complications. The mean hospital stay was 2.2 days (range 2 to 3 days). All five returned to their activity within a week. No long-term complications were seen in all patients throughout an average follow-up period of 10.6 months (range 8-14). The benefits of laparoscopic cholecystectomy in children are clear and obvious. It is safe and effective and should now be the treatment of choice for cholelithiasis in pediatric patients.

Incidence of thromboembolic complications after laparoscopic cholecystectomy: review of the literature.

The purpose of this study was to quantify the risk of thromboembolic complications after laparoscopic cholecystectomy by a survey of the literature. We reviewed 60 laparoscopic cholecystectomy series consisting of 153,832 patients. The average mortality was 0.08%. The average rate of fatal pulmonary embolism was 0.02% and total pulmonary embolism 0.06%. The average rate of reported deep vein thrombosis was 0.03%. We conclude that laparoscopic cholecystectomy is a safe procedure, and the rate of clinically evident postoperative thromboembolic complications is probably lower than after conventional cholecystectomy. A lingering bias due to the overrepresentation of young and healthy patients early in the era of laparoscopic cholecystectomy could, however, still affect these figures. An underreporting of the lesser complications is likely. The risk is not negligible, though, and some authors have recommended thromboembolism prophylaxis, although further studies are necessary to find the optimal prophylaxis strategy. The true incidence is possible to establish only by using objective diagnostic methods for surveillance.

Changes in hepatic bile secretion following cholecystectomy.

The volume and compositon of hepatic bile was studied in anesthetized dogs before and approximately 18 weeks after cholecystectomy. Dogs had common duct cannulation, cystic duct ligation, and temporary occlusion of the pylorus. An intravenous infusion of sodium taurocholate, 9 muEq per minute, was given throughout the experiment. Bile volume, electrolyte composition, bile salt output, and 14C-mannitol clearance were determined during infusion of sodium taurocholate alone and after addition of secretin, 4 U. per kilogram per hour, to the infusion. Cholecystectomy then was done and the same experiment was repeated 18 weeks later. Cholecystectomy significantly increased bile volume, sodium and chloride output, and 14C-mannitol clearance both in response to taurocholate alone and to taurocholate plus secretin. Bile salt output and bicarbonate output were unchanged. The study shows that cholecystectomy significantly alters the volume and composition of hepatic bile. The data indicate that cholecystectomy does not affect ductular function or hepatic secretion of bile salts but that canalicular function is altered significantly.

Laparoscopic cholecystectomy alleviates pain in patients with acalculous biliary disease.

Our goal was to determine whether laparoscopic cholecystectomy is a safe and effective means of treatment for patients with acalculous cholecystitis. We reviewed the charts of 243 patients diagnosed with acalculous cholecystitis or biliary dyskinesia. Follow-up telephone interviews to measure degree of patient satisfaction and relief of preoperative symptoms were conducted. Hepatobiliary scanning results and postoperative symptom resolution were compared. One hundred seventy-one patients (94.5%) reported complete or partial resolution of symptoms postoperatively. Although 99 patients had symptoms reproduced with cholecystokinin injection during scanning, there was no significant correlation between these findings and alleviation of pain with cholecystectomy. There was no significant correlation between pain resolution after cholecystectomy and abnormal pathologic findings. Patients who suffered symptoms for a longer period of time preoperatively were more likely to be satisfied with the result of laparoscopic cholecystectomy. Laparoscopic cholecystectomy alleviates symptoms in many patients with acute or chronic acalculous cholecystitis or biliary dyskinesia with minimal morbidity.
