Laparoscopic cholecystectomy (LC) for gallstone disease is the most common surgical procedures performed in Western countries and bile leaks remain a significant cause of morbidity (0.2-2%). The bile ducts of Luschka (DL)are small ducts which originate from the right hepatic lobe, course along the gallbladder bed, and usually drain in the extrahepatic bile ducts. Injuries to these ducts are the second most frequent cause of bile leaks after cholecystectomy. Aim of our study is build a literature review starting from our experience.PERSONAL EXPERIENCE: Forty four patients with abdominal bile collections post-cholecystectomy by suspected bile leak under-went endoscopic retrograde cholagio-pancreatography (ERCP). A complete cholangiogram was obtained in 42 patients(95.5%). In according to the magnitude of bile leak daily, we subdivided the patients in two groups: a) < 180 ml/daily,and b) > 180 ml/daily. The most common site of the leak was the cystic duct stump (94.5%), followed by DL (2 patient = 5.5%). 10 Fr stent insertion after endoscopic sphincterotomy (ES) was the most common intervention. In 6 patients (14%) a 7 Fr naso-biliary drainage was inserted. On an intention-to-treat basis, endoscopic intervention at ERCP had 100% success rate for resolution of the leak. The median time for resolution of the leak was 8 and 12 days in the first and second group respectively. No mortality ERCP-related were recorded. Early minor complications occurred in 7/42 (16.5%) patients.
A literature search using MEDLINE's Medical Subject Heading terms was used to identify recent articles.Cross-references from these articles were also used.
ERCP is the most common diagnostic and therapeutic method used in bile leaks post-cholecystectomy. Most patients with DL leaks are symptomatic, and most leaks are detected postoperatively during the first postoperative week. Reduction of intra-ductal pressure with ES and stent or naso-biliary tube insertion will lead to preferential flow of bile through the papilla, thus permitting DL injuries to heal. This is the most common treatment modality used. In a minority of patients,re-laparoscopy is performed. In such cases, the leaking DL is visualized directly and ligation usually is sufficient treatment.Simple drainage is adequate treatment for a small number of asymptomatic patients with low-volume leaks.
DL leaks occur after cholecystectomy regardless of gallbladder pathology or urgency of operation. They have been encountered more frequently in the era of LC Intraoperative cholangiography does not detect all such leaks. ERCP with ES and stent placement are the most common effective diagnostic and therapeutic methods used. Intraoperative and perioperative adjunctive measures, such as fibrin glue instillation and pharmacologic relaxation of the sphincter of Oddi,can potentially be used in lowering the incidence and in the treatment of DL leaks.

    ABSTRACT: Introduction: Laparoscopic cholecystectomy (LC) is a well standardized technique. There are two main approaches, proposed by French and American Schools. They have similar operative times, but different arrangements for site ports insertions and for patients and operators' position at operative bed. Although we can foresee new scenarios for the next future (robotics, SILS, NOTES, minilaparoscopy), it seemed interesting to describe a simple variation to LC introduced in the last years in our experience relative to the positioning of operators and patient during standard American technique. Methods: In a retrospective analysis of 140 patients operated on for LC in the last two years (70 with French technique and 70 with "American modified" technique) we compared the following parameters: laparotomic conversion, duration of operation, hospital stay, morbidity and mortality rates. Results: Conversion to laparotomy, length of operative time and hospital stay were similar. Morbidity rates were slightly different, but it did not show statistically significant differences between the two groups. Mortality was nil. Considerations: Our variant to LC seems to be almost a compromise between the two main techniques. Our operators' arrangement gave a greater comfort for surgeons during LC and our results were similar to those reported with adoption of French and American approaches. These considerations led us to judge our variation safe and reliable.

    ABSTRACT: Background/Aim: Laparoscopic cholecystectomy is currently the gold standard treatment for gallstone disease. Bile duct injury is a rare and severe complication of this procedure, with a reported incidence of 0.4% to 0.8% and is mostly a result of misperception and misinterpretation of the biliary anatomy. Robotic cholecystectomy has proven to be a safe and feasible approach. One of the latest innovations in minimally invasive technology is fluorescent imaging using indocyanine green (ICG). The aim of this study is to evaluate the efficacy of ICG and the Da Vinci Fluorescence Imaging Vision System in real-time visualization of the biliary anatomy. A total of 184 robotic cholecystectomies with ICG fluorescence cholangiography were performed between July 2011 and February 2013. All patients received a dose of 2.5 mg of ICG 45 minutes prior to the beginning of the surgical procedure. The procedures were multiport or single port depending on the case. No conversions to open or laparoscopic surgery occurred in this series. The overall postoperative complication rate was 3.2%. No biliary injuries occurred. ICG fluorescence allowed visualization of at least 1 biliary structure in 99% of cases. The cystic duct, the common bile duct, and the common hepatic duct were successfully visualized with ICG in 97.8%, 96.1%, and 94% of cases, respectively. ICG fluorescent cholangiography during robotic cholecystectomy is a safe and effective procedure that helps real-time visualization of the biliary tree anatomy.
