Value and consequences of routine intraoperative cholangiography during cholecystectomy

Since the introduction of laparoscopic cholecystectomy (LC), an increase in accidental common bile duct (CBD) injuries of up to 1.2-1.6% has been reported. In the present prospective study of 1,710 patients undergoing cholecystectomy (1,241 LC procedures and 469 open cholecystectomies [OC]), we tested the predicative value of routine intraoperative cholangiography (IOC). The IOC was feasible in 92.4% of the cases in the LC group and in 83% of cases in the OC group and presented a complete depiction of the extrahepatic bile system in 98.3%. Anatomic variations of the bile duct system, which influenced the operative management, were found in 13.2% of cases (13.4% LC versus 12.8% OC). In 2.5% of the patients, preoperatively undetected CBD stones were also found. Method-specific complications did not occur in any of the patients. Additionally, in a controlled subgroup analysis of 163 patients, we evaluated preoperative intravenous cholangiography (IVC) and IOC. Intravenous cholangiography showed only 72.4% of the operation-relevant anatomic variations (vs. 100% by IOC); in 6.1% of the cases, there were reactions to the dye (vs. none in IOC), and in only 28.6% of the patients, CBD stones were detected (vs. 71.4% IOC). There were four bile duct injuries (0.29%) during LC and two (0.4%) during OC. All injuries were detected intraoperatively and fixed in the same setting without postoperative complications. In conclusion, we recommend the use of routine IOC during cholecystectomy. By this technique, anatomic variations of the bile duct system will be visualized and therefore accidental injuries will be avoided.

Management of Preoperatively Suspected Choledocholithiasis: A Decision Analysis

Background  The management of symptomatic or incidentally discovered common bile duct (CBD) stones is still controversial. Of patients undergoing elective cholecystectomy for symptomatic cholelithiasis, 5–15% will also harbor CBD stones, and those with symptoms suggestive of choledocholithiasis will have an even higher incidence. Options for treatment include preoperative endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy (ERCP/ES) followed by laparoscopic cholecystectomy, laparoscopic cholecystectomy with intraoperative cholangiogram (LC/IOC), followed by either laparoscopic common bile duct exploration (LCBDE) or placement of a common bile duct double-lumen catheter with postoperative management. The purpose of this analysis was to determine the optimal management of such patients. Methods  A decision analysis was performed to analyze the management of patients with suspected common bile duct stones. The basic choice was between preoperative ERCP/ES followed by LC, LC/IOC followed by LCBDE, or common duct double-lumen catheter (Fitzgibbons tube) placement with either expectant management or postoperative ERCP/ES. Data on morbidity and mortality was obtained from the literature. Sensitivity analysis was done varying the incidence of positive CBD stones on IOC with associated morbidity and mortality. Results  One-stage management of symptomatic CBD stones with LC/LCBDE is associated with less morbidity and mortality (7% and 0.19%) than two-stage management utilizing preoperative ERCP/ES (13.5% and 0.5%). Sensitivity analysis shows that there is an increase in morbidity and mortality for LC/LCBDE as the incidence of positive IOC increases but are still less than two-stage management even with a 100% positive IOC (9.4%, 0.5%). If a double-lumen catheter is to be used for positive IOC, the morbidity would be higher than two-stage management only if the positive IOC incidence is more than 65% but still with no mortality. Conclusion  LCBDE has lower morbidity and mortality rates compared to preoperative ERCP/ES in the management of patients with suspected CBD stones even if the chance of CBD stones reaches 100%. Using a common duct double-lumen catheter may be considered if LCBDE is not feasible and the chance of CBD stone is less than 65%.

Routine laparoscopic ultrasound can significantly reduce the need for selective intraoperative cholangiography during cholecystectomy

Background The use of intraoperative cholangiography (IOC), routinely rather than selectively, during laparoscopic cholecystectomy (LC) is controversial. Recent findings have shown laparoscopic ultrasound (LUS) to be safe, quick, and effective not only for screening of the bile duct for stones, but also for evaluating the biliary anatomy. This study aimed to evaluate, on the basis of the LC outcome and the cost of LUS and IOC, whether and how much the routine use of LUS would be able to reduce the need for IOC. Methods During LC, LUS was used routinely to screen the bile duct for stones and to evaluate the biliary anatomy, whereas IOC was used selectively only when LUS was unsatisfactory or unsuccessful. Results For 193 (96.5%) of 200 patients, LUS was completed successfully, whereas IOC was needed for 7 patients (3.5%). Bile duct stones were identified in 20 patients (10%). For the detection of bile duct stones, LUS yielded 19 true-positive, 175 true-negative, 0 false-positive, and 1 false-negative results. It had a sensitivity of 95%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 99.4%. The postoperative complications included bile leaks from the liver bed in two patients and a retained bile duct stone in one patient. If IOC had been used selectively in a traditional manner on the basis of preoperative risk factors, IOC would have been needed for 77 patients (38.5%). The total cost of LUS plus IOC for the current 200 patients was $26,256. The total estimated cost of selective IOC, if it had been performed for the 77 patients, would have been $31,416. Conclusions Routine LUS accurately diagnosed bile duct stones and significantly reduced the need for selective IOC from a potential 38.5% to an actual 3.5% without adversely affecting the outcome of the LC or increasing the overall cost. The routine use of LUS during LC is accurate and cost effective.     

For patients with predicted low risk for choledocholithiasis undergoing laparoscopic cholecystectomy, selective intraoperative cholangiography and postoperative endoscopic retrograde cholangiopancreatography is an effective strategy to limit unnecessary procedures

Background  There is debate about whether intraoperative cholangiography (IOC) should be performed routinely or selectively during laparoscopic cholecystectomy (LC) in patients with suspected choledocholithiasis. The timing of endoscopic retrograde cholangiopancreatography (ERCP) in these patients also is an issue. We reviewed the experience in our center, where a management algorithm limiting ERCP in relation to LC was adopted. Methods  We retrospectively reviewed every LC performed by one surgeon during 6 years and the related ERCPs. Results  A total of 264 LCs were performed. In 30 patients, stones were cleared or excluded by preoperative ERCP. In the remaining 234 LCs, 31 of 34 IOCs were successfully performed. Two of 31 IOCs were positive for bile duct stones; stone removal was successful in each patient at subsequent ERCP. Only 10 of 201 patients who did not have IOC required postsurgical ERCP within 10 weeks of LC, 3 of whom had common bile duct stones at ERCP. Conclusions  For patients who underwent LC, we performed selective IOC with postoperative ERCP for positive studies. Review of our experience using this algorithm showed it to be a powerful tool in limiting unnecessary ERCPs. Our data suggest that routine preoperative ERCP cannot be justified. Selective IOC during LC misses relatively few cases of biliary stones; these can be managed quickly by experienced endoscopists.     

Laparoscopic ultrasound as the primary method for bile duct imaging during cholecystectomy

Background Intraoperative fluorocholangiography (IOC) has been the standard method for bile duct imaging during cholecystectomy. Laparoscopic ultrasound (LUS) has been evaluated as a possible alternative, but has been used less frequently. The authors examined the evolving use of these two methods to assess the relative utility of LUS as the primary method for routine bile duct imaging during laparoscopic cholecystectomy (LC). Methods This study analyzed a prospective database containing 423 consecutive cholecystectomies performed by one attending surgeon in an academic medical center between 1995 and 2005. Results Intraoperative bile duct imaging was performed in 371 (94%) of 396 LCs performed for cholelithiasis. As recorded, IOC was performed in 239 cases, LUS in 236 cases, and both in 104 cases. Choledocholithiasis was present in 50 patients (13%). Common bile duct stones (CBDS) were identified by LUS in 3% of the patients without preoperative indicators of CBDS, and in 10% of the patients with one or more indicators. As shown by the findings, LUS had a positive predictive value of 100%, a negative predictive value of 99.6%, a sensitivity of 92.3%, and a specificity of 100% for detecting CBDS. Also, LUS identified clinically significant bile duct anatomy in 6% of the patients. In 1995, LUS was used for 20% of cases, whereas by 2005, it was used for 97% of cases. Conversely, the use of IOC decreased from 93% to 23%. Conclusions With moderate experience, LUS can become the primary routine imaging method for evaluating the bile duct during LC. It is as reliable as IOC for detecting choledocholithiasis. In addition, LUS can locate the common bile duct during difficult dissections. On the basis of this experience, LUS is used currently in nearly all LCs and is the sole method for bile duct imaging in 75% of these cases. IOC is used as an adjunct to LUS when LUS imaging is inadequate, when stronger clinical indicators of choledocholithiasis are present, or when biliary anatomy remains uncertain.
