ABSTRACT

Bile leak remains a serious complication after hepatectomy. The conventional leak test by intrabiliary injection of normal saline solution is not sensitive. The authors present a new bile leak test using indocyanine green (ICG) fluorescence. After hepatic transection, ICG solution (.05 mg/mL) was intrabiliarily injected through a transcystic tube under distal common bile duct clamping, and fluorescent images were visualized using an infrared camera system. The ICG leak test was performed in 27 patients undergoing hepatectomy without biliary reconstruction. Bile leaks were intraoperatively found in 8 patients and fixed, resulting in no postoperative leaks. There was no adverse reaction to ICG. In contrast, postoperative bile leaks occurred in 2 of 32 patients who received the conventional leak test with normal saline solution between April 2007 and March 2008. The new bile leak test by ICG fluorography is useful to prevent postoperative bile leak.

    ABSTRACT: Background Improved imaging methods and surgical techniques have created a new era in hepatopancreatobiliary (HPB) surgery. Despite these developments, visual inspection, palpation, and intraoperative ultrasound remain the most utilized tools during surgery today. This is problematic, though, especially in laparoscopic HPB surgery, where palpation is not possible. Optical imaging using near-infrared (NIR) fluorescence can be used for the real-time assessment of both anatomy (e.g., sensitive detection and demarcation of tumours and vital structures) and function (e.g., assessment of luminal flow and tissue perfusion) during both open and minimally invasive surgeries. Methods This article reviews the published literature related to preclinical development and clinical applications of NIR fluorescence imaging during HPB surgery. Results NIR fluorescence imaging combines the use of otherwise invisible NIR fluorescent contrast agents and specially designed camera systems, which are capable of detecting these contrast agents during surgery. Unlike visible light, NIR fluorescent light can penetrate several millimetres through blood and living tissue, thus providing improved detectability. Applications of this technique during HPB surgery include tumour imaging in liver and pancreas, and real-time imaging of the biliary tree. Conclusions NIR fluorescence imaging is a promising new technique that may someday improve surgical accuracy and lower complications.

    • "A new technique described by Japanese surgeons involves injection of indocyanine green (ICG) dye through the transcystic tube followed by fluorescent imaging. The authors reported that small leaks not identified by a leak test using saline could be detected using this technique [58]. ICG fluorescence cholangiography after hepatic resections in 52 cases was compared to a conventional leak test using ICG dye alone in 50 cases in another study. "

    ABSTRACT: Bile leaks from the intrahepatic biliary tree are an important cause of morbidity following hepatic surgery and trauma. Despite reduction in mortality for hepatic surgery in the last 2 decades, bile leaks rates have not changed significantly. In addition to posted operative bile leaks, leaks may occur following drainage of liver abscess and tumor ablation. Most bile leaks from the intrahepatic biliary tree are transient and managed conservatively by drainage alone or endoscopic biliary decompression. Selected cases may require reoperation and enteric drainage or liver resection for management.

    ABSTRACT: We report a case of postoperative bile leakage that was successfully managed by intrabiliary ethanol ablation. A 68-year-old man with peritoneal and liver metastases from a jejunal gastrointestinal stromal tumor (GIST), which were refractory to molecular-targeted agents, underwent extended left lobectomy and peritoneal tumor resection. Bile leakage from the drainage tube persisted at a constant volume of 100 ml per day. On the 20th postoperative day, fistulography through a drainage tube and endoscopic cholangiography revealed biliary leakage from the bile ducts of segments 5 and 1. Since these bile ducts did not communicate with the proximal hilar bile ducts, two 5F balloon catheters were separately advanced into the leaking bile ducts via the drainage tube on day 30, and 1 ml absolute ethanol was injected into both of these catheters for 10 minutes. After three sessions of ethanol ablation, the bile leakage stopped. Although the bile leakage from segment 1 relapsed five days later, it gradually decreased and then stopped again until day 70. Intrabiliary ethanol ablation using the interventional technique is useful for managing bile leakage after hepatectomy when the leaking distal bile duct is isolated from the proximal biliary tree.
