Real-time indocyanine green fluorescence technique reduces anastomotic leakage in bilioenteric anastomosis: A case report and literature review.

Background: Anastomotic leakage is a serious complication that can occur in bilioenteric anastomosis surgery, leading to significant morbidity and mortality. Currently, practitioners rely on subjective measures to determine anastomotic perfusion and mechanical integrity, which have limitations. The use of indocyanine green fluorescence technology has become increasingly widespread in clinical practice, especially in gastrointestinal-related surgery. This technique has a unique role in evaluating the blood perfusion of anastomoses and reducing the incidence of anastomotic leakage. However, there have been no reports of its use in bilioenteric anastomosis surgery. Further research is needed to investigate the potential benefits of indocyanine green fluorescence technology in improving outcomes and reducing complications in this type of surgery.

Case Summary: a 50-year-old female patient underwent total laparoscopic radical resection of cholangiocarcinoma. During the surgery, indocyanine green fluorescence technology was used to complete the biliary intestinal anastomosis under full visual and dynamic monitoring. The patient recovered well after the operation without experiencing biliary leakage or other complications.

Conclusion: The present case study underscores the potential advantages associated with the incorporation of intraoperative real-time indocyanine green (ICG) technology in bilioenteric anastomosis surgery. By facilitating enhanced visualization and assessment of anastomotic perfusion and mechanical stability, this state-of-the-art technique may help mitigate the occurrence of anastomotic leaks while simultaneously improving patient outcomes. Notably, intravenous administration of ICG at a dose of 2.5 mg/kg, administered 24 h prior to surgery, has been found to yield optimal visualization outcomes.
