[Influence of biliary decompression technique on the outcomes of reconstructive surgery]

To evaluate bile ducts injuries and effect of biliary decompression technique on the outcomes of reconstructive surgery.

There were 21 patients with biliary injury during cholecystectomy, 20 patients with cholelithiasis, and 1 patient after surgery for perforated duodenal ulcer. Their age was 22-81 years (mean 54.3 years). Primary surgery through median laparotomy was followed by biliary injury in 12 patients, laparoscopic cholecystectomy - in 6 patients, open laparoscopy - in 3 patients. Patients were divided into 2 groups. In group 1 (n=11) biliary injury was diagnosed intraoperatively, in group 2 (n=10) - in 2-11 days after primary procedure. According to European Association for Endoscopic Surgery (EAES) 2013 classification biliary injury type 1 was found in 5 patients, type 2 - in 9 cases, high damage involving confluence (type 3) - in 1 patient, type 4 - in 1 patient, and type 6 - in 5 patients. Endoscopic retrograde cholangiopancreatography in 3 patients revealed that biliary drainage output after laparoscopic cholecystectomy was caused by cystic duct clipping failure, endoscopic papillosphincterotomy was successfully used for biliary drainage output (type 6). In 3 patients operated through median laparotomy biliary excretion cessation was observed after 2-3 days that indicated damage of aberrant bile ducts.

Bile outflow into gastrointestinal tract was restored in 11 out of 16 patients with iatrogenic biliary injury types 1-4, external biliary drainage was used in 4 patients due to their severe condition and abdominal inflammatory changes. Biliary fistulae occurred in 5 out of 8 patients in both groups after primary reconstructive surgery. Biliary stricture was observed in 3 cases due to external biliary drainage failure followed by peritonitis. 7 patients underwent reconstructive surgery with positive result. Mortality was absent. In 1 patient with biliary fistula outcome is unknown.

Transumbilical biliary drainage is optimal during reconstructive surgery.
