Evaluation of laparoscopic management of common bile duct stones in 220 patients

Background: The aim of this study was to evaluate the feasability and results of laparoscopic management of common bile duct stones (CBDS). Methods: From October 1990 to November 1996, 220 patients with CBDS have been managed laparoscopically. CBDS were suspected or diagnosed preoperatively in 130 patients (59.1%) and at intraoperative cholangiography (IOC) in 90 patients (40.9%). A transcystic duct extraction (TCDE) was attempted in 112 patients and a primary choledochotomy in 108 patients. Results: TCDE was successful in 77 cases (68.8%). The 35 failures were treated by 29 laparoscopic choledochotomies, 1 intraoperative and 5 postoperative endoscopic sphincterotomies (ES). A choledochotomy was thus performed in 137 cases and was successful in 133 cases (97.1%). The four failures were managed by three laparotomies and one postoperative ES. The overall success rate was 95.5% (210/220). There was 4 deaths (0.9%) within the 1^st postoperative month in ASA 3 patients and the morbidity rate was 9.1% (20/220). There were 7 residual stones (3.2%). Conclusions: Laparoscopic desobstruction of CBDS appears to be safe and effective and has the advantage to be a single-stage procedure. It could become in the future with refinement of instrumentation and skill of surgeons the best treatment for the majority of patients harboring CBDS.

Results of the routine use of a modified endoprosthesis to drain the common bile duct after laparoscopic choledochotomy

Background: One hundred eighty-one patients were submitted to laparoscopic common bile duct exploration. Methods: A transcystic approach was used in 147 patients, choledochotomy in 14, and both in 20. The indications to perform a choledochotomy included stones larger than 20 mm, stones proximal to the cystic duct entrance, and cases in which the transcystic duct approach proved impossible or unsuccessful. Results: The common bile duct was drained by a T-tube in four patients, by laparoscopic sphincterotomy in one, by laparoscopic choledochoduodenostomy in one, and by a 10 Fr endoprosthesis in 28. The stent placement was technically feasible in all patients but one. The biliary drainage was adequate. Mean hospital stay was 2.1 days. Complication was limited to one umbilical infection and one self-limited biliary leak. Conclusions: The procedure proved to be technically simple, safe, and efficient, and resulted in a low morbidity rate and short hospital stay. Received: 29 March 1996/Accepted: 12 June 1996

Laparoscopic endobiliary stenting as an adjunct to common bile duct exploration

Background: The management of common bile duct stones (CBDS) in the era of operative laparoscopy is evolving. Several minimally invasive techniques to remove CBDS have been described, including preoperative endoscopic retrograde cholangiopancreatography (ERCP), postoperative ERCP, lithotripsy, laparoscopic transcystic common bile duct exploration, and laparoscopic choledochotomy with common bile duct exploration (CBDE). Because of the risks and limitations of these procedures, we utilize laparoscopically placed endobiliary stents as an adjunct to CBDE. Methods: Sixteen patients underwent laparoscopic common bile duct exploration (LCBDE) by either choledochotomy or the transcystic technique with placement of endobiliary stents. These patients were identified during laparoscopic cholecystectomy as having occult choledocholithiasis, using routine dynamic intraoperative cholangiography. Results: CBDS were successfully removed in all patients as demonstrated by completion cholangiography and intraoperative choledochoscopy. Eighty percent of patients were discharged the following day; the first three patients in this series were observed for 48 h prior to discharge. No patient required T-tube placement and closed suction drains were removed the morning after surgery. Stents were removed endoscopically at 1 month. Six- to 30-month follow-up demonstrates no complications to date. Conclusions: Laparoscopic endobiliary stenting reduces operative morbidity, eliminates the complications of T-tubes, and allows patients to return to unrestricted activity quickly. We recommend laparoscopically placed endobiliary stents in patients undergoing LCBDE.     

Laparoscopic common bile duct exploration by choledochotomy

Background: Management of cholelithiasis and choledocholithiasis usually requires two separate teams—the gastroenterologist/surgical endoscopist and the laparoscopic surgical team. This requires two separate procedures that potentially increase the overall morbidity and cost. Laparoscopic common bile duct exploration by choledochotomy (LCBDE-C) averts this problem with a single approach. Methods: In 1990–1991, unsuspected stones found at laparoscopy with intraoperative cholangiogram done routinely underwent postoperative ERCP. Residual stones had been found after ERCP in 16 of 22 preoperative ERCP patients and we began to seek an alternative technique. Laparoscopic common bile duct exploration by choledochotomy has achieved a high rate of success. Results: Technically successful LCBDE-C has been accomplished in 143 of 148 patients (96.6%). Retained bile duct stones have been found on postoperative cholangiogram in three patients (2.0%), all of which have been successfully removed by postoperative ERCP. Thus 140 or 148 patients had their bile duct successfully cleaned by the one-step technique alone (94.6%). Conclusions: We believe that most laparoscopic surgeons who have acquired the skills of intracorporeal suturing can be successful at laparoscopic common bile duct exploration by choledochotomy. The disadvantage of T-tube presence will likely be eliminated by future developments with intraoperative antegrade sphincterotomy-like procedures, but the ability to see both proximal and distal biliary tree with the choledochotomy in all cases seems to offer more than adequate results at this point in the evolution of the laparoscopic approach to calculus biliary tract disease.

Follow-up of 161 unselected consecutive patients treated laparoscopically for common bile duct stones

Background: Aim was to study the incidence of recurrent ductal stones and of biliary strictures at follow-up after laparoscopic treatment of gallstones and common bile duct stones and to update the short-term results. Methods: Ductal stones were proven in 161 patients of 1,975 (8.1%) undergoing laparoscopic cholecystectomy. Laparoscopic transcystic CBD exploration was the method of choice. If this was unsuccessful, laparoscopic choledochotomy was performed. After treatment, all patients were enrolled in a continued, ongoing follow-up study. Results: Laparoscopic CBD exploration was completed in 157 cases (transcystic 107, choledochotomy 50). Retained stones occurred in eight patients (5%) and major complications (cystic duct leakage, hemoperitoneum) in six (3.8%); mortality occurred in one high-risk patient (0.6%). Follow-up available in 154 patients (two unrelated deaths) for a period of up to 62 months showed the occurrence of recurrent ductal stones in five cases (3.2%) and no signs of bile stasis, suggestive of ductal stricture, on the basis of clinical and laboratory findings. Conclusions: This prospective, ongoing follow-up study demonstrates that laparoscopic treatment of gallstones and common bile duct stones in unselected patients is feasible and safe.

Laparoscopic treatment for common bile duct stones by transcystic papilla balloon dilatation technique

The laparoscopic transcystic common bile duct (CBD) approach is becoming increasingly more refined as an ideal technique to deal with gallbladder stones (GBS) and common bile duct stones (CBDS) during a single operation. Our method, transcystic CBD exploration and papilla balloon dilatation (PBD), is an easier, safer, and less invasive technique than the transcystic approaches that have previously been reported. With our method, a sheath is introduced through the cystic duct into the CBD in order to allow catheter exchange, and the CBDS is flushed out through the papilla into the duodenum after PBD. We applied our new technique, without complication, to a patient with GBS and CBDS. Our technique is one of the safest, easiest, and least invasive methods for the treatment of patients with GBS and CBDS. Received: 22 July 1998/Accepted: 7 March 1999     

Laparoscopic choledochotomy for bile duct stones

In the era of laparoscopic surgery, treatment strategies for common bile duct stones remain controversial. Laparoscopic choledochotomy is usually indicated only when transcystic duct exploration is not feasible. However, laparoscopic choledochotomy provides complete access to the ductal system and has a higher clearance rate than the transcystic approach. In addition, primary closure of the choledochotomy with a running suture and absorbable clips facilitates the procedure. Therefore, to avoid postoperative biliary stenosis, all patients with bile duct stones can be indicated for choledochotomy, except for those with nondilated common bile duct. Placement of a C-tube also provides access for the clearance of possible retained stones by endoscopic sphincterotomy as a backup procedure. C-tube placement, in contrast to T-tube insertion, is advantageous in terms of a relatively short hospital stay. In conclusion, laparoscopic choledochotomy with C-tube drainage is recommended as the treatment of choice for patients with common bile duct stones.

Laparoscopic common bile duct stone clearance with flexible choledochoscopy

Background Laparoscopic common bile duct exploration (LCBDE) is as safe and efficient as endoscopic retrograde cholangiopancreatography (ERCP) in achieving bile duct clearance from stones. No clear guidelines are available on LCBDE with respect to indications for trans-cystic approach versus choledochotomy, or regarding when to use either flexible choledochoscopy (FCD) or intraoperative cholangiography (IOC) guidance. Methods From January 2001 until November 2006, 113 consecutive patients with common bile duct stones (CBDS) and gallbladder in situ were enrolled in a prospective non-randomized study to undergo laparoscopic cholecystectomy with LCBDE on an intention-to-treat basis. Twenty-three patients were aged 80 years or older with severe comorbidity. Preoperative ERCP with attempted stone clearance was performed in 24 patients. Laparoscopic common bile duct exploration was attempted for CBDS in the presence of acute cholecystitis in 24 patients. Laparoscopic common bile duct exploration was performed via the trans-cystic approach in 83 patients and via choledochotomy in 30 patients. Flexible choledochoscopy was used in 79 patients and IOC guidance in 34 patients. Results No mortality occurred. Postoperative complications were encountered in nine patients. Laparoscopic stone clearance of the bile duct was successful in 91.8% of the patients. Median length of hospital stay (LOS) was two days (range, 0 to 24 days) after trans-cystic LCBDE and six days (range, 2 to 34 days) after stone clearance via choledochotomy (p < 0.0001). Choledochotomy was performed for CBDS measuring an average of 11.5 mm (range, 5 to 30 mm) in diameter while trans-cystic LCBDE was successful for stones measuring an average of 5 mm (range, 2 to 14 mm) (p < 0.0001). Mean duration of surgery was 75 minutes (range, 30 to 180 minutes) when FCD was used, and 107 minutes (range, 45 to 240 minutes) in patients undergoing LCBDE under IOC guidance (p < 0.0001). Conclusion Laparoscopic cholecystectomy and LCBDE with stone extraction can be performed with high efficiency, minimal morbidity and without mortality. A trans-cystic approach is feasible in most patients, whereas choledochotomy should be restricted to large bile duct stones that cannot be extracted through the cystic duct. The use of flexible choledochoscopy is preferable to IOC guidance.     

Laparoscopic common duct exploration in the management of choledocholithiasis

BACKGROUND: Optimal treatment strategies for addressing common duct stones at laparoscopic cholecystectomy remain controversial. The study presents the authors' experience with laparoscopic common bile duct exploration (LCBDE). METHODS: A retrospective review was performed of 71 LCBDEs performed over 5 years using either transcystic duct flushing and mechanical techniques, transcystic duct basket retreival techniques, or laparoscopic choledochotomy. RESULTS: Laparoscopic CBDE resulted in ductal clearance in 61 of 71 (85%) cases with only 1 case of unsuspected retained common duct stones and only 1 major complication. Review of the cases that did not result in common duct clearance suggests that the success rate of laparoscopic CBDE could be increased. CONCLUSIONS: Laparoscopic CBDE is an effective treatment for concurrent gallstones and common duct stones and avoids the potential morbidity of an endoscopic sphincterotomy. General surgeons with adequate training and experience can perform laparoscopic CBDE safely and effectively.     

Transcystic biliary decompression after direct laparoscopic exploration of the common bile duct

Background: A purpose-designed transcystic common bile duct (CBD) decompression cannula is described for use as an alternative to T-tube insertion following laparoscopic direct CBD exploration. This permits safe primary closure of the choledochotomy. Methods: Following direct supraduodenal laparoscopic clearance of large common bile duct stones, the biliary decompression cannula is inserted percutaneously inside its peel-away sheet over a guide-wire into the CBD via the cystic duct. When in place, the cannula is secured to the cystic duct by two catgut extracorporeal Roeder knots and the choledochotomy is then closed. The terminal multiperforated S-shaped segment of the Cuschieri biliary decompression cannula prevents postoperative dislodgement. Results: Transcystic decompression of the extrahepatic biliary tract using the Cuschieri cannula has been used in 12 patients who underwent laparoscopic supraduodenal CBD exploration for large or occluding stones. There was no instance of postoperative dislodgement of the cannula and all patients had effective drainage of the common bile duct (average 300 ml bile per 24 h). The procedure was uncomplicated in all but one patient who developed self-limiting leakage from the CBD suture line in the early postoperative period. The median hospital stay after surgery was 4 days, with a range of 3 to 10 days. The cystic duct decompression cannula was capped and sealed under an occlusive dressing at the time of discharge. Removal of the cannula was carried out without any complications as a day case 11–16 days after surgery. Conclusions: Transcystic biliary decompression is safe and effective. The experience with is use indicates that compared to T-tube drainage, transcystic decompression may accelerate recovery and reduce the hospital stay in patients following laparoscopic direct exploration of the CBD. Its insertion is less technically demanding than placing a T-tube through the choledochotomy. Transcystic decompression with complete primary closure of the CBD realizes the full benefits of the single-stage management of common bile duct calculi and permits confirmation of complete stone clearance after surgery.

Laparoscopic exploration of the common bile duct

Background: Bile duct clearance at open cholecystectomy had become normal surgical practice before the introduction of laparoscopic cholecystectomy. However, perceived technical difficulties have deterred many surgeons from treating common bile duct stones at the time of laparoscopic cholecystectomy. This has led to a reliance on preoperative clearance of ducts known to have stones and postoperative clearance of ducts found to have stones at operation or those that subsequently develop complications of retained stones. Methods: The authors describe a series of 120 consecutive bile duct explorations carried out between April 1991 and February 1997 in a series of 1,237 laparoscopic cholecystectomies. Results: Laparoscopic exploration and clearance of the bile ducts was achieved in 89% of cases in the whole series, and 97% success was attained in the last 60 cases, which also were associated with a decrease in operating time. Conclusions: We believe that for surgeons familiar with open common bile duct exploration and laparoscopic cholecystectomy, the next logical step is laparoscopic exploration of the common bile duct at the time of cholecystectomy, which is safe and readily mastered.

Laparoscopic common bile duct exploration

OBJECTIVE: To describe the technique of laparoscopic common bile duct exploration (LCBDE) with high clearance rates, low morbidity, and mortality rates. SUMMARY BACKGROUND DATA: LCBDE is well accepted by patients because treatment is obtained during the same anesthesia. If one stage therapy for gallstones and common bile duct stones provides success rates equivalent to those of the sequential approach, with lower costs, this should be considered the standard of care. METHODS: From September 1991 to March 2007, 5201 laparoscopic cholecystectomies were performed at S?o José Avaí Hospital. LCBDE was carried out in 481 patients (9.25%). RESULTS: Of 481 LCBDE, 225 (46.78%) were managed using a transcystic approach and 183 (38.05%) with choledochotomy (114 with transcystic choledochotomy and 69 with longitudinal opening of the common bile duct). Successful laparoscopic stone clearance was achieved in 468 (97.3%). An elective postsurgical endoscopic sphincterotomy were done on the 13 (2.70%) patients not cleared laparoscopically. Seven patients had unexpected retained stones. CONCLUSIONS: LCBDE during laparoscopic cholecystectomy solves 2 problems during the same anesthesia with high success rates and may be employed successfully.     

Towards T-tube free laparoscopic bile duct exploration: a methodologic evolution during 300 consecutive procedures.

OBJECTIVE: To establish a simple, reproducible, and safe technique of laparoscopic common bile duct exploration (CBDE) with high clearance rates and low morbidity and mortality rates. SUMMARY BACKGROUND DATA: For most general surgeons, laparoscopic CBDE appears an unduly complex and demanding procedure. Since the introduction of laparoscopic cholecystectomy, many surgeons use endoscopic cholangiography (ERC) and endoscopic sphincterotomy as their only option in treating bile duct stones. ERC is more specific if used after surgery, but it carries an appreciable morbidity rate and has the disadvantage of requiring a second procedure to deal with bile duct stones. To this end, various methods of laparoscopic CBDE have been developed. METHODS: Between August 1991 and February 1997, 300 consecutive unselected patients underwent laparoscopic CBDE. RESULTS: Of 300 laparoscopic CBDE procedures, 173 (58%) were managed using a transcystic approach and 127 (42%) with choledochotomy. Successful laparoscopic stone clearance was achieved in 271 (90%). Of the 29 (10%) patients not cleared laparoscopically, 10 had an elective postsurgical ERC, 12 were converted to an open procedure early in the series, and 7 had unexpected retained stones. There was one death (mortality rate 0.3%) and major morbidity occurred in 22 patients (7%). The last 100 procedures were performed from July 1995 to February 1997, and stone clearance was unsuccessful in only two patients. CONCLUSIONS: Laparoscopic transcystic basket extraction of common duct stones under fluoroscopic guidance is a relatively quick, successful, and safe technique. Choledochotomy, when required, is associated with a higher morbidity rate, particularly with T-tube insertion, and the authors advocate primary bile duct closure with or without insertion of a biliary stent as a more satisfactory technique for both surgeon and patient. Most patients with gallbladder and common duct calculi should expect a curative one-stage laparoscopic procedure without the need for external biliary drainage or ERC.     

Actual management of common bile duct stones: a continuous evolving approach

The management of common bile duct stones (CBDS) has recently changed regarding either a more precise diagnosis of patients at high-risk to harbor CBDS and either the development of new therapeutic modalities. In patients with preoperative predictive suspicion of CBDS, new non-invasive radiologic and endoscopic investigations are now available, namely 3-D spiral CT-cholangiography and magnetic resonance cholangio-pancreatography on one hand, and endoscopic ultrasonography on the other hand. With the development of laparoscopic surgery, two strategies have emerged in order to maintain the minimally invasive nature of the procedure: perioperative endoscopic sphincterotomy or laparoscopic common bile duct exploration. However, considerable laparoscopic expertise, advanced and expansive technologies are required to achieve successful laparoscopic treatment of CBDS. An appropriate intraoperative strategy is mandatory during laparoscopic common bile duct exploration, with specific indications for the transcystic route and for laparoscopic choledochotomy, according to patient's biliary anatomy and stone's characteristics. A preliminary controlled trial has proved the safety, efficacy and excellent postoperative results of such approach. However, the best option of management for patients with CBDS remains open to discussion and the therapeutic choice should depend on the local hospital availability of technical expertise.     

Laparoscopic management of common bile duct stones

Laparoscopic common bile duct exploration (CBDE) was the subject of a multi-institutional study on 226 patients from 19 major hospital centers. Female patients predominated (2.3:1); the average age was 54; 75% of cases were chronic, and the remainder were acute. Although 97% had preoperative ultrasonograms, only 12% showed a stone in the dilated common bile duct. The alkaline phosphatase was elevated in 41% and the serum bilirubin in 28% of cases. Preoperative endoscopic retrograde cholangiography with sphincterotomy (ERC-ES) was performed in 8.5%; there was a successful stone extraction in less than half the cases. Cholangiography was performed in 99.5%, and in 94% of those cases, stones were found.In 83% of cases, stones were removed through the transcystic approach, and in 17% removal was throughout the CBD. In the majority of cases, the choledochoscope and wire basket (34%), irrigation (33%), or a combination of both was employed. In the transcystic group, 5% were converted to open procedures due to technical difficulty, as contrasted with the trans-CBD route, where the conversion rate was 19%. There were two ductal injuries. Minor complications occurred in 5.7% within 24 h; there was one death (0.4%). Within 30 days, the morbidity rate was 7% and there were no deaths. Retained stones were discovered in 2.6% of cases.Laparoscopic CBDE is a feasible approach for CBD stones which permits a definitive procedure in one stage, without pre- or postoperative ES. It is a skill which should be mastered by the biliary surgeon. Further improvement in instrumentation and technique should make the laparoscopic approach not only comparable but preferable to the standard open choledocholithotomy.Presented at the annual meeting of the Society of American Gastrointestinal Endoscopic Surgeons (SAGES), Nashville, Tennessee, USA 18–19, April 1994     

Evaluation of laparoscopic treatment of common bile duct stones in a prospective series of 505 patients: indications and results

BACKGROUND: The aim of this prospective study was the evaluation of the laparoscopic treatment of common bile duct stones (CBDS) and its indications. METHODS: Five hundred five patients who underwent laparoscopic treatment of CBDS from October 1990 to September 2006 were included in the prospective study. The mean age of the patients was 63 years (range = 19-93). Four hundred fifteen patients were classified ASA I and ASA II and 90 were ASA III and ASA IV. CBDS were suspected or diagnosed preoperatively in 373 patients (73.8%) and diagnosed at intraoperative cholangiography (IOC) in 132 patients (26.2%). A transcystic duct extraction (TCDE) was attempted in 254 patients (50.4%) and a primary choledochotomy in 251 patients (49.6%). Biliary drainage after choledochotomy was used in 148 cases (48.8%). RESULTS: TCDE was successful in 191 cases (75.2%).The 63 failures were managed by laparoscopic choledochotomy in 53 cases and by endoscopic sphincterotomy (ES) in 10 cases. A choledochotomy was thus performed in 304 patients and successful in 295 cases (97%). The nine failures were managed by six conversions to laparotomy (2%) and three postoperative ES. The overall success rate was 96.2%. The morbidity rate was 7.9% with 4.8% of local complications and 3.1% of general complications. The mortality rate was 1%. There were 14 residual stones (2.8%) that were managed by a second laparoscopy in two cases and by ES in 12 cases with four failures managed by laparotomy in one case and laparoscopy in three cases. CONCLUSION: Laparoscopic management of CBDS was effective in more than 96% of cases and particularly safe in ASA I and ASA II patients. It has the advantage over ES followed by laparoscopic cholecystectomy (LS) to be a one-stage procedure.     

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 transcystic common bile duct exploration.

This study reviews the results of transcystic common bile duct exploration (CBDE) for unsuspected stones found during laparoscopic cholecystectomy by a single surgeon in 150 consecutive patients. Fluoroscopic cholangiography was attempted in all but four patients. If the cholangiogram appeared to show common bile duct (CBD) stones, a 5 Fr, 8-mm ureteral stone basket was passed through the cystic duct into the duodenum, opened, and trolled through the CBD. Routine cholangiography was successful in 131 of 144 attempts (90%). An indication for CBDE was found by cholangiogram in seven patients (5%). Two cholangiograms were falsely positive. Stones were removed in five patients. Completion cholangiograms were normal in all patients. One patient developed mild pancreatitis but was discharged 2 days after laparoscopic cholecystectomy. The remainder were discharged on postoperative day 1. One patient was readmitted on postoperative day 2, possibly having passed a retained stone. Fluoroscopic CBDE was successful in clearing the CBD in all patients in this small series and deserves further evaluation.
