BACKGROUND: Biliary complications, especially bile leaks, are an important cause of early postoperative morbidity and, rarely, mortality after liver transplant. The risk is higher in living donor liver transplant (LDLT) compared to deceased donor liver transplant (DDLT). Attempts to reduce bile leaks have included refinements in the biliary anastomosis technique and use of various external and internal stents, with inconsistent benefits. Recent availability and successful use of the absorbable Archimedes stent has prompted its intrabiliary placement across the anastomosis. METHODS: In this retrospective study, we analyzed the data of 20 adult patients who underwent a liver transplant with duct-to-duct biliary anastomosis using the Archimedes stent. Both DDLT and LDLT were performed using cava-preserving hepatectomy followed by standard implantation methods. Duct-to-duct biliary anastomosis was performed in all cases using interrupted sutures with extracorporeal knots over an absorbable intrabiliary stent. In addition to standard postoperative care, patients were monitored for bile leak. RESULTS: Nine DDLTs had a single anastomosis over a 10-Fr stent. Out of 11 LDLT patients, 7 had a single anastomosis and 4 patients had 2 anastomoses, all over a 6-Fr stent. Two patients died, 1 as a result of graft primary nonfunction and another because of multidrug-resistant pneumonia. One patient had ascending cholangitis owing to stent migration in the duodenum. This episode was treated with endoscopic stent removal and appropriate antibiotics, with good recovery. None of the other patients had bile leaks, biloma, or stent-related complications. CONCLUSIONS: Archimedes internal absorbable biliary stents can be safely used in both living and deceased donor liver transplants to prevent bile leaks.
