Intraoperative Fluorescent Cholangiography Using Indocyanine Green Fluorescence for Identification and Treatment of Bile Leaks After Urgent Laparoscopic Cholecystectomy

Abstract

Introduction: Laparoscopic cholecystectomy (LC) is one of the most common surgical procedures performed worldwide.1 Postoperative bile leaks caused by bile duct injuries (BDIs) are serious complications after LC, resulting in a prolonged length of hospital stay, increased costs, morbidity, and mortality rates.2 Incidence of BDIs during LC is ~0.4%–1.5%.1 Intraoperative fluorescent cholangiography using indocyanine green fluorescence (ICG-C) is a safe method to observe the biliary tree and may be useful to prevent postoperative bile leaks after LC and hepatic surgery.1,2 However, detection of bile leaks using the ICG-C during LC has limited evidence in international literature.3–8 This video illustrates how to use ICG-C to identify and treat a bile leak after an urgent LC. Materials and Methods: A 54-year-old man with a history of hypertension, diabetes mellitus, cholelithiasis, and hepatic abscesses was admitted with right upper quadrant pain and fever. An urgent CT scan of the abdomen showed acute cholecystitis associated with a large pericholecystic abscess. A percutaneous cholecystostomy (PC) was placed and nonoperative management with intravenous antibiotic was started. On the seventh postprocedural day, the PC was accidentally removed, and a second CT scan of the abdomen showed a reduction of the pericholecystic abscess size, and a subhepatic fluid collection. An urgent LC was performed, and two surgical drains were placed (one subhepatic and one suprahepatic). On the first postoperative day, a low-flow biliary output (250 mL/day) from the subhepatic drainage was associated with a gradual deterioration of the patient's clinical condition. Considering the low flow rate of the biliary fistula, nonoperative management was carried out; on the second post-operative day the patient presented hypotension, oliguria, fever (temperature 38.2°C), and worsening right upper abdominal pain with signs of diffuse peritonitis. The hematologic investigations showed a WBC 17,560/mL, Hb 10.7 g/dL, C-Reactive Protein 17.66 mg/dL, normal liver function tests, and normal bilirubin levels. Owing to signs of septic shock and diffuse signs of peritonitis, an urgent surgical exploration was performed. After the induction of anesthesia, 2.5 mg of Indocyanine Green was intravenously injected. Eight minutes later, the ICG-C demonstrated exactly and in real-time the biliary leak on the liver surface, coming from a subvesical bile duct. Two laparoscopic Roeder's knots were placed to repair the injury. Two surgical drains were placed. Results: The postoperative period was uneventful, with a progressive improvement of the patient's performance status, vital parameters, and laboratory tests. The surgical drains were serosanguinous with low output and both were removed on postoperative day 9. The patient was discharged on day 10 in good clinical condition. Conclusions: One of the most common causes of LC-associated biliary leaks are injuries to the subvesical bile ducts. ICG-C clearly identifies these bile spots on the liver surface during surgery, allowing them to be repaired immediately and prevent biliary fistulas. ICG-C is a safe, easy, repeatable, and noninvasive method to identify bile leaks during surgery. ICG-C may be useful to prevent and treat bile leaks after LC, especially in complicated cholecystitis.5,6 Authors have received and archived patient consent for video recording/publication in advance of video recording of procedure.
