BILIARY PERITONITIS, CHOLANGITIS, BILE LEAKAGE, LIVER, SECONDARY, CHOLESTASIS, LEAKAGE, COMPLICATIONS
The study aimed to compare the benefits and risks of the CS technique and the IS technique for patients undergoing BEA. The primary endpoint of this study was the time required to complete the anastomosis. Secondary outcome parameters were BEA-associated postoperative complications with and without operative revision of the BEA, including bile leakage, cholestasis, and cholangitis. Further secondary outcome parameters were morbidity, including other surgical and non-surgical complications and mortality up to day 30 after the intervention as well as survival. Short-term complications were defined as complications occurring within 1 month after surgery, whereas long-term complications were defined as complications occurring, at the earliest, 1 month up to 24 months after surgery, including anastomotic stenosis, jaundice, and cholestasis. Bile leakage was defined in accordance with the International Study Group of Liver Surgery (ISGLS) definition as elevated drain bilirubin levels, which exceeded at least three times the serum bilirubin concentration or as the need for radiological or operating intervention resulting from biliary collections or biliary peritonitis
