A balanced approach to choledocholithiasis

Background: We set out to review and evaluate the results of an algorithm for managing choledocholithiasis in patients undergoing laparoscopic cholecystectomy. Methods: We performed retrospective review of patients with choledocholithiasis at the time of laparoscopic cholecystectomy (LC) between March 1993 and August 1999. All patients were operated on under the direction of one surgeon (M.E.A), following a consistent algorithm that relies primarily on laparoscopic transcystic common bile duct exploration (TCCBDE) but uses laparoscopic choledochotomy (LCD) when the duct and stones are large or if the ductal anatomy is suboptimal for TCCBDE. Intraoperative endoscopic retrograde sphincterotomy (ERS) is done if sphincterotomy is required to facilitate common bile duct exploration (CBDE). Postoperative endoscopic retrograde cholangiopancreatography (ERCP) is utilized when this fails. Preoperative ERCP is used only for high-risk patients. Results: A total of 728 LC were performed, and there were 60 instances (8.2%) of choledocholithiasis. Primary procedures consisted of 47 TCCBDE; 37 of them required no other treatment. In five cases, the stones were flushed with no exploration. Intraoperative ERS was performed three times as the only form of duct exploration. LCD was utilized twice; one case also required intraoperative ERS, and the other had a postoperative ERCP for stent removal. One patient with small stones was observed, with no sequelae. Preoperative ERCP was done twice as the primary procedure. Of the 10 cases that were not completely cleared by TCCBDE, three had a postoperative ERCP and seven had an intraoperative ERS, one of which required a postoperative ERCP. There were three complications (6%) related to CBDE, with no long-term sequelae. There were four postoperative complications (6.7%) and no deaths. The mean number of procedures per patient was 1.12. The average postoperative hospital stay was 1.8 days (range, 0-14). Conclusions: Choledocholithiasis can be managed safely by laparoscopic techniques, augmenting with ERCP as necessary. This protocol minimizes the number of procedures and decreases the hospital stay.

The efficacy of preoperative endoscopic retrograde cholangiopancreatography in the detection and clearance of choledocholithiasis.

BACKGROUND AND OBJECTIVES: Endoscopic retrograde cholangiopancreaticography has been reported to have a high success rate in the detection and treatment of choledocholithiasis. Although there is growing enthusiasm for laparoscopic common bile duct clearance, many patients who present with gallbladder disease and suspected choledocholithiasis have endoscopic retrograde cholangiopancreatography performed with choledocholithiasis cleared if detected. These patients are then referred for laparoscopic cholecystectomy. The purpose of this study is to determine the efficacy of preoperative endoscopic retrograde cholangiopancreatography in the diagnosis and clearance of bile duct stones at our institution. METHODS: A retrospective review was performed of all patients at this institution who underwent preoperative endoscopic retrograde cholangiopancreatography for suspected choledocholithiasis followed by laparoscopic cholecystectomy from January 1997 through July 1998. RESULTS: Common bile duct stones were detected endoscopically in 12 of 17 (71%) patients. We found serum bilirubin level to be the best predictor of choledocholithiasis. In 12 of 12 procedures, the endoscopist performed an endoscopic sphincterotomy with stone extraction and reported a fully cleared common bile duct. Intraoperative cholangiogram performed during subsequent cholecystectomy revealed choledocholithiasis in 4 of these 12 patients. Laparoscopic techniques successfully cleared the choledocholithiasis in 3 of these patients with open techniques necessary in the fourth. CONCLUSIONS: Our data suggests that even after presumed successful endoscopic clearance of the bile duct stones, many patients (33% in our series) still have choledocholithiasis present at the time of cholecystectomy. We recommend intraoperative cholangiography at the time of cholecystectomy even after presumed successful endoscopic retrograde cholangiopancreatography with further intervention, preferably laparoscopic, to clear the choledocholithiasis as deemed necessary.     

Laparoscopic transcystic bile duct stenting in the management of common bile duct stones

Background : The management of patients with common bile duct stones associated with stones in the gall bladder remains controversial. Methods : Over the three‐year period from 1996 to 1999, patients with cholelithiasis and known choledocholithiasis, or choledocholithiasis found at laparoscopic cholecystectomy, were initially treated by placing a stent across the sphincter of Oddi. The stent was pushed along a guide wire through the cystic duct and then down the common bile duct, before the cystic duct was closed. Subsequently, the stent was used to facilitate performance of a needle knife endoscopic sphincterotomy. The stent was then removed, a cholangiography was performed and the common bile duct was cleared. Patients with persistent jaundice usually had a preoperative endoscopic retrograde cholangio‐pancreatography. Results : Transcystic stenting was the ‘intention‐to‐treat’ basis of therapy for 56 of the patients. The placement of the stent only failed once when the stent became trapped in the cystic duct. Complications of the operation included: pain and jaundice (n = 2), cholangitis (n = 1), and pulmonary embolus (n = 1). The median postoperative hospitalization was 2 days (range: 1–15). Five further patients had common bile duct stones removed via a choledochotomy; a stent was placed through the choledochotomy before its closure. The selective common bile duct cannulation rate at the first endoscopic retrograde cholangio‐pancreatography, was 98%. A second endoscopic retrograde cholangio‐pancreatography was required in 15% of patients. The only complication of all the endoscopic procedures was a single case of mild cholangitis; there were no cases of pancreatitis. Conclusion : A treatment option open to all surgeons for non‐jaundiced patients with known choledocholithiasis or choledocholithiasis found at operative cholangiogram, is the transcystic stenting of the sphincter of Oddi at the time of laparoscopic cholecystectomy. At a subsequent sitting, the common bile duct can be safely cleared endoscopically using a sphincterotomy facilitated by the stent.

The utility of laparoscopic common bile duct exploration in the treatment of choledocholithiasis

Laparoscopic common bile duct exploration (CBDE) was performed in 24 patients over a 23-month period. Fourteen of these patients were suspected preoperatively of harboring common bile duct (CBD) calculi. Of these, endoscopic sphincterotomy was unsuccessful in eight. Laparoscopic CBDE was performed either transcystically or via a choledochotomy. In all cases, completion cholangiography demonstrated that the CBD was free of stones. All patients were sent home with drains placed in their extrahepatic biliary system. Mean hospital stay was 2.7 days. There was no mortality. The overall morbidity rate was 29.1%. It included one trocar site infection (4.1%), four cases of mild postoperative amylasemia (16.6%), and two cases of retained stones (8.3%) seen in two patients on follow-up tube cholangiography that were successfully extracted percutaneously. The authors feel that laparoscopic CBDE is a safe and effective method of CBD stone removal that offers an alternative to preoperative ERCP and sphincterotomy.     

Laparoscopic common bile duct exploration.

Operative common bile duct exploration, performed in conjunction with cholecystectomy, has been considered the treatment of choice for choledocholithiasis in the presence of an intact gallbladder. With the advent of laparoscopic cholecystectomy, the management of common bile duct stones has been affected. More emphasis is being placed on endoscopic sphincterotomy and options other than operative common duct exploration. Because of this increasing demand, we have developed a new technique for laparoscopic common bile duct exploration performed in the same operative setting as laparoscopic cholecystectomy. A series of five patients who successfully underwent common bile duct exploration, flexible choledochoscopy with stone extraction, and T-tube drainage, all using laparoscopic technique, is reported. Mean postoperative length of hospital stay was 4.6 days. Outpatient T-tube cholangiography was performed in all cases and revealed normal ductal anatomy with no retained stones. Follow-up ranged from 6 weeks to 4 months, and all patients were asymptomatic and had normal liver function tests.     

Stone clearance and risk factors for failure in laparoscopic transcystic exploration of the common bile duct

Background Laparoscopic cholecystectomy has become a gold standard globally. At the time of surgery, 5 to 10% of patients have coexisting stones in the common bile duct (CBD). There are several alternatives in treating these patients. We have chosen to try to extract the CBD stones at the primary operation by laparoscopic transcystic CBD exploration. Methods During the years 1994–2002 laparoscopic attempt of exploration of the CBD was made in 207 patients. Data was prospectively collected in a database, and was analyzed using unconditional logistic regression for risk factor analysis. Results In 155 of the 207 patients an attempt of transcystic CBD exploration was made and it was successful in 132 cases (85%). The median operating time was 184 minutes (range 89–384 minutes) and the median postoperative hospital stay was one day (range 1–31 days). The odds ratio for failure in stone clearance among patients with a bile duct diameter greater than 6 mm was 6.90 (95% confidence interval (CI): 0.87–54.61) compared to patients with a bile duct diameter of 6 mm or less. There was a significant threefold increase in risk among patients with stones of greater than 5 mm diameter compared to patients with stones 5 mm or less. Conclusions The laparoscopic transcystic exploration of the CBD had a high frequency of stone clearance and low morbidity in the present study. Moreover, large stones are a risk factor for failure in stone clearance.     

Laparoscopic surgery and the common bile duct

Many biliary tract surgeons have now reached a level of sophistication with laparoscopic cholecystectomy that they are now able to deal with the common bile duct at the same time. Preoperative endoscopic cholangiography can be reserved for cases where choledocholithiasis has a high degree of probability. This has served to decrease the number of negative studies. The surgeon has five choices regarding stones confirmed by operative cholangiography during laparoscopic cholecystectomy: (1) do nothing, hoping the stones will pass spontaneously or that a postoperative sphincterotomy with stone extraction will be successful; (2) perform a transcystic laparoscopic common bile duct exploration (best for stones less than 1 cm and distal to the cystic duct); (3) perform a laparoscopic common bile duct exploration by choledochotomy (best for large stones in patients with common bile ducts greater than 1 cm. It is also the preferred approach with stones proximal to the insertion of the cystic duct.); (4) perform an intraoperative sphincterotomy with stone extraction, either retrograde or antegrade (this approach has some proponents but has not gained popularity among the majority of surgeons); and (5) place a double lumen catheter through the cystic duct with a proximal lumen in the common bile duct and the distal lumen in the duodenum. This can be used for serial postoperative cholangiography to confirm spontaneous stone passage or falsely positive operative cholangiograms. It is useful in situations when laparoscopic common bile duct exploration equipment or surgeon expertise is not available. If stones persist, a guidewire can be introduced through the distal lumen of the catheter for a guidewire-assisted sphincterotomy. Other CBD interventions that have been reported include laparoscopic biliary bypass and resection of choledochal cysts. Malignant lesions should not be approached by a laparoscopic method except in unusual circumstances.

Laparoscopic surgical treatment of cholecysto-choledochal calculi. A single step solution

The laparoscopic era has created a new basis for the management of choledocholithiasis. Many surgeons now regard laparoscopic cholecystectomy and exploration of the common bile duct as the "gold standard". The main advantages of single-stage treatment consist in a significantly shorter hospital stay, very low complication rates and a reduction of average hospital costs. Among 601 cases of cholelithiasis treated over the period from 1994 to 1999, we report 73 cases of common-bile-duct stones. Surgical sphincterotomy was performed in 20 cases and endoscopic sphincterotomy in 24; only in 7 cases was choledochotomy and/or hepaticojejunostomy (3 cases) performed for critical situations. Twenty-two cases of cholelithiasis were treated by laparoscopic cholecystectomy and exploration of the common bile duct. Stone extraction was obtained with a balloon catheter or Dormia basket via a choledochotomy. Surgery was completed by suturing, cholangiography and the placement of sub-hepatic drainages. No mortality or long-term complications were recorded with the laparoscopic procedure; only two immediate complications were reported, both of which were biliary leakages (9%) that resolved spontaneously. With the other procedures, high rates of mortality, morbidity, hospital admissions and technical failure were registered. We regard laparoscopic exploration of the common bile duct as the treatment of choice for bile-duct stones when combined with cholecystectomy. We reserve ERCP plus endoscopic sphincterotomy only for common-bile-duct stones alone, without a gallbladder or gallstones. Open surgery is performed in particular situations such as Mirizzi's syndrome or when other procedures have failed to yield satisfactory results.     

Feasibility of laparoscopic common bile duct exploration in a rural centre

BACKGROUND: Laparoscopic common bile duct exploration has emerged as a preferred option for the management of choledocholithiasis. The present study sought to review the feasibility of this technique in a rural centre. METHODS: A comprehensive retrospective review was undertaken of all patients who underwent surgical treatment of biliary calculi in Lismore, NSW (Australia), between January 1996 and December 2002. RESULTS: During the study period, 1567 consecutive patients underwent laparoscopic cholecystectomy, of whom 82 (5.2%) had choledocholithiasis identified at intraoperative cholangiography. A total of 86 laparoscopic common bile duct explorations were undertaken in these patients, 37 (43%) via a transcystic approach, and 49 (57%) via a laparoscopic choledochotomy. All common bile duct calculi were successfully removed in 78 cases, representing an overall duct clearance rate of 90.7%. Complications were noted in seven patients, a morbidity rate of 8.5%. Median operative time for the procedure over the study period was 173 min. Median hospital stay was 6 days for all patients. CONCLUSIONS: Laparoscopic common bile duct exploration can be successfully undertaken in a rural setting by general surgeons who have appropriate laparoscopic experience, and should be the procedure of choice for the management of choledocholithiasis in these patients. It should not be restricted to specialized surgical departments in major referral centres.     

The laparoscopic approach to cholecysto-choledocholithiasis.The "rendez-vous " technique

A combined method of endoscopic sphincterotomy (ES) with common bile duct (CBD) stone extraction and laparoscopic cholecystectomy under general anesthesia for a single-session treatment of patients with colecysto-choledocholithiasis is described. The so called "rendez-vous" technique consists in: standard laparoscopic cholecystectomy with intraoperative cholangiography followed by ES if common bile duct stones are detected. The sphincterotome is driven across the papilla through a wire guide inserted by transcystic route. Nine patients were scheduled for "rendez-vous" approach. At intraoperative cholangiography 4 have had CBD stones. Endoscopic sphincterotomy and CBD clearance were successful in all patients. No complication was encountered. Mean postoperative hospital stay was 5 days. The laparo-endoscopic "rendez-vous" approach is feasible, it reduces the number of unnecessary ERCP examinations, it lowers the morbidity related with endoscopic sphincterotomy and shortens the hospital stay.     

Laparoscopic management of choledocholithiasis

The authors report on a group of 114 patients with common bile duct (CBD) stones who were treated by laparoscopic surgery. Management through the cystic duct was considered the first option. Choledochotomy was used for those patients in which the cystic approach was not possible or was unsuccessful. Transcystic lithotripsy was considered for patients with CBD stones in disproportion with the size of the cystic duct. Laparoscopic antegrade sphincterotomy was indicated as a drainage procedure. The transcystic approach was used in 89.5% of the patients; choledochotomy was used in 6.2%; and both ways were used in 4.3%. Different procedures were used, including mechanical and electrohydraulic lithotripsy, choledochotomy with T-tube or endoprostheses drainage, laparoscopic sphincterotomy, end-to-end common bile duct anastomosis, and choledochoduodenum anastomosis. One of the patients was in the 21st week of pregnancy. The laparoscopic approach to choledocholithiasis was successfully performed in 94.8% of the patients. Mean hospital stay was 1.7 days. There was a 6.2% incidence of complications and the mortality rate was 0.9%. In 84.3% of the patients, the transcystic approach was used successfully, with a complication rate of 4.9% and a mean hospital stay of 1.6 days. Three patients were converted to open surgery early in this series. Thus far, one patient has presented residual CBD stones. The results obtained suggest that laparoscopic common bile duct exploration is a technically feasible procedure, with low complication and mortality rates, although it requires adequate selection of patients and a variety of techniques and types of equipment.     

Choledocholithiasis: evolving intraoperative strategies

In the era of open cholecystectomy, common bile duct stones were approached by traditional choledocholithotomy. Retained or recurrent stones discovered after cholecystectomy were approached by endoscopic extraction techniques or repeat surgery. With the advent of laparoscopic cholecystectomy, the approach to choledocholithiasis became more problematic as techniques for laparoscopic extraction were rudimentary. Preoperative endoscopic retrograde cholangiopancreatography rapidly became an adjunct to laparoscopic cholecystectomy when common duct stones were likely. Experience, however, revealed that many of these procedures were unnecessary. With developing sophistication of laparoscopic techniques, a variety of approaches to common duct stones developed. These included: transcystic extraction, direct laparoscopic choledocholithotomy, intraoperative endoscopic retrograde cholangiopancreatography, antegrade sphincterotomy, and transcystic placement of a common duct stent with subsequent endoscopic sphincterotomy and stone extraction. It is the purpose of this article to define the current role of each of these methods in the laparoscopic approach to choledocholithiasis.     

The role of laparoscopy in the management of common bile duct obstruction in children

BACKGROUND: Laparoscopic common bile duct exploration is commonplace in adults; however, this procedure is not often performed in children. The goal of this study was to evaluate the results of laparoscopic common bile duct exploration in children. METHODS: Of 50 patients undergoing laparoscopic cholecystectomy, six patients (12%) had obstructing lesions of the common bile duct (CBD). Five children underwent laparoscopic common bile duct exploration, and one child had a preoperative endoscopic sphincterotomy and stone removal. RESULTS: The mean age at laparoscopic CBD exploration was 11.6 years (range, 5-16). The obstructing lesion was visualized by intraoperative cholangiography in all five patients. The mean operative time for laparoscopic cholecystectomy along with CBD exploration was 215 min (range, 160-282). The transcystic laparoscopic CBD exploration was performed using a 7-Fr, multichannel rigid, or 10-Fr flexible fiberoptic cystoscope. The stones were either pushed into the duodenum with the scope or extracted through the cystic duct using a 3-Fr Segura basket. In one patient, a candidial ball disintegrated during an attempt to remove it with the basket. A repeat cholangiogram at the end of each procedure showed an anatomically normal CBD with free flow of contrast into the duodenum. All patients enjoyed a quick recovery. They were started on a regular diet on the same day of surgery and discharged on the 1st or 2nd postoperative day. One patient with sickle cell disease developed a pulmonary infarction and required 5 additional days of hospitalization. One patient developed recurrent choledocholithiasis 6 months after laparoscopic exploration and was treated successfully with endoscopic sphincterotomy and stone extraction. CONCLUSIONS: Laparoscopic CBD exploration can be performed safely at the time of the cholecystectomy in children. Endoscopic sphincterotomy before cholecystectomy is not necessary. We recommend laparoscopic CBD exploration for obstructing lesions of the CBD. Endoscopic sphincterotomy should be reserved for recurrent lesions of the CBD after laparoscopic cholecystectomy.     

A stratified intraoperative surgical strategy is mandatory during laparoscopic common bile duct exploration for common bile duct stones

Background: Open exploration and endoscopic sphincterotomy (ES) remain the preferred treatment of common bile duct stones (CBDS). The recent spread of laparoscopy has worsened the dilemna of choosing between surgical and endoscopic treatment of CBDS. The aim of this study was to critically evaluate the results of our preliminary experience with laparoscopic common bile duct exploration (CBDE) for CBDS. Methods: Ninety-two consecutive patients were prospectively submitted to laparoscopic CBDE. Surgical strategy included an initial transcystic approach or laparoscopic choledochotomy. Failure of stone clearance was managed by conversion to open CBDE or by postoperative ES. Electrohydraulic lithotripsy and papillary balloon dilatation were selectively used. Stone clearance was assessed by choledochoscopy and control cholangiography. Results: The overall laparoscopic stone clearance in this series was 84% (transcystic route 63% and choledochotomy 93%). Conversion to laparotomy was mandatory in 12% of the patients because of incomplete stone clearance and in 5% because of intraoperative complications. Postoperative ES was required in 4% of the patients, giving an overall surgical success rate of 96%. When indicated (small and limited number of stones located below the cysticocholedochal junction, with a dilated and patent cystic duct) the transcystic route had the lower success rate, the higher complication rate, and the shorter operative time and postoperative hospital stay. When indicated (accessible and dilated common bile duct over 7 mm), laparoscopic choledochotomy had the higher success rate, the lower complication rate, the longer operative time, and the longer postoperative hospital stay, which is related to associated external biliary drainage. The hospital mortality included two high-risk patients (2%) and the complications rate was 15%. Conclusions: Laparoscopic CBDE is safe in selected patients. A stratified intraoperative surgical strategy is mandatory in deciding between a transcystic route and choledochotomy with specific indications for each approach. When feasible, laparoscopic choledochotomy is more efficient and safe than the transcystic route, but it is associated with a longer postoperative hospital stay, which is due to external biliary drainage.

Laparoscopic Common Bile Duct Exploration

Since the introduction of laparoscopic cholecystectomy, the management of common bile duct (CBD) stones has undergone significant change. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy is now routinely done in cases where the diagnosis of choledocholithiasis is suspected preoperatively, with clearance of the bile ducts before laparoscopic cholecystectomy. Intraoperative discovery of CBD stones by cholangiography represents a challenge to the surgeon, who must make a decision about when to perform laparoscopic CBD exploration, convert to open surgery, or send the patient for ERCP during the postoperative period. Because ERCP has a definite failure rate, laparoscopic CBD exploration can be a treatment option. Among 2500 laparoscopic cholecystectomies done by our group from January 1991 to June 1997, 50 patients (2%) underwent laparoscopic CBD exploration, 13 by the transcystic technique and 37 by choledocotomy, with a conversion rate of 8% and a hospital stay of 4.3 days. One patient died from complicated pancreatitis following ERCP and unsuccessful extraction of a CBD stone. We obtained our goal of a CBD free of stones in 92% of the cases. We conclude that laparoscopic CBD exploration is an effective method for treating choledocolithiasis that allows management of this pathology in one stage, although it requires advanced laparoscopic skills and adequate equipment.
