Abstract
Introduction
The value of routine abdominal drainage after hepatectomy remains controversial. Although drains have traditionally been used to detect bile leakage or postoperative bleeding and to evacuate intra-abdominal collections, their routine use after elective liver resection has increasingly been questioned.
Materials and methods
A systematic review and metaanalysis of randomized controlled trials comparing routine abdominal drainage with no drainage after elective hepatectomy was performed. PubMed/MEDLINE, Embase, Web of Science, and the Cochrane Library were searched from inception to 1 April 2026 using predefined terms related to hepatectomy, drainage, and randomized trials. The outcomes of interest included overall postoperative morbidity, postoperative mortality, wound-related complications, bile leakage or biliary fistula, subphrenic or perihepatic fluid collection, and length of hospital stay. Risk of bias was assessed using the Cochrane RoB 2 tool.
