Abstract
Bile leak after biliary reconstruction remains a major complication. Herein, we examined the perioperative factors associated with bile leak in 81 patients undergoing bilio-jejunal anastomosis. Especially, we focused our attention on the efficacy of indocyanine green (ICG) bile leak test, which was done by an infrared camera system observation after intrabiliary ICG injection. This test intraoperatively visualized 11 bile leaks. Bile leak postoperatively developed in 5 of 42 patients without intraoperative bile leak test and 1 of 39 undergoing leak test. The exceptional bile leak in ICG leak test group was due to jejunal congestion. Among the perioperative factors, the presence of hepatectomy was significantly associated with the postoperative bile leak.
In conclusion, hepatectomy is associated with the postoperative bile leak. ICG leak test is useful to prevent postoperative bile leak, if unexpected trouble around the bilio-jejunal anastomosis does not happen.
