Mechanical hepaticojejunostomy: can we use a circular stapler as a viable and safe alternative? -a retrospective study of a single center.

Background: Since the first years of the 1980s, some authors described the use of mechanical stapler for the creation of anastomosis in biliary surgery. However, the use of these devices has not spread during the following decades, and nowadays most centers usually craft hand-sewn anastomosis.

Methods: We retrospectively collected data from medical records, surgical registries and computerized databases about the use of mechanical circular staplers for the creation of hepaticojejunostomy at our institution.

Results: From 2012 to 2020, 11 stapled hepaticojejunostomy for both neoplastic and non-neoplastic diseases were performed at our institution. The mean age of the patient was 74, with a sex distribution of 5 men and 6 women. The mean preoperative common bile duct diameter was 19 mm. Preoperative blood samples showed mean total bilirubin of 6.95 mg/dL. No intraoperative complications were reported. Two patients (18%) had minor postoperative complications (1 wound dehiscence and 1 episode of melena that required blood transfusions), while no major complications occurred. No patients developed biliary fistula or anastomotic dehiscence. No one dies within 30 days from surgery. The mean postoperative length of stay was 13 days.

Conclusions: According to our limited experience, stapled hepaticojejunostomy seems to be a safe and effective technique in selected patients.
