Previous Gastrectomy independent risk factor for POBL Risk in laparoscopic liver resection Patients: Study

Postoperative bile leakage is a common cause of major complications following liver resection. Although the use of laparoscopy for liver surgery has expanded rapidly, bile leakage after laparoscopic liver resection has not been well described.

This study aimed to identify the risk factors for bile leakage following laparoscopic liver resection. A total of 510 consecutive patients who underwent laparoscopic liver resection for hepatic tumors between January 2009 and December 2023 were included in this study. Bile leakage was defined according to the criteria established by the International Study Group of Liver Surgery. Its occurrence, consequences, clinicopathological characteristics, and surgical details were evaluated retrospectively.

Risk factors were identified using a multivariable logistic regression analysis. Bile leakage occurred in a small number of patients. It was more frequently observed in older individuals, those with a history of gastrectomy, and those who experienced other postoperative complications or extended hospital stays. Multivariable analysis revealed that a history of gastrectomy was independently associated with the occurrence of bile leakage.

All affected patients were successfully treated using percutaneous drainage, with some also requiring endoscopic nasobiliary drainage. A previous gastrectomy was identified as an independent risk factor for bile leakage in patients undergoing laparoscopic liver resection.
