Hepaticojejunostomy (HJ) is the classical reconstruction for benign biliary stricture. Endoscopic management of anastomotic complications after hepaticojejunostomy is extremely difficult. In this work we assess a modified biliary reconstruction in the form of bilio-entero-gastrostomy (BEG) regarding the feasibility of endoscopic access to HJ and management of its stenosis if encountered.
From October 2008 till February 2011 all patients presented to the authors with benign biliary stricture who needed bilio-enteric shunt were considered. For each patient bilio-entero-gastrostomy (BEG) of either type I, II or III was constructed. In the fourth week postoperatively, endoscopy was performed to explore the possibility to access the biliary anastomosis and perform cholangiography.
BEG shunt was performed for seventeen patients, one of whom, with BEG type I, died due to myocardial infarction leaving sixteen patients with a diagnosis of postcholecystectomy biliary injury (9), inflammatory stricture with or without choledocholithiasis (5) and strictured biliary shunt (2). BEG shunts were either type I (3), type II (3) or type III (10). Endoscopic follow up revealed successful access to the anastomosis in 14 patients (87.5%), while the access failed in one type I and one type II BEG (12.5%). Mean time needed to access the anastomosis was 12.6 min (2-55 min). On a scale from 1–5, mean endoscopic difficulty score was 1.7. One patient (6.25%), with BEG type I, developed anastomotic stricture after 18 months that was successfully treated endoscopically by stenting. These preliminary results showed that, in relation to the other types, type III BEG demonstrated the tendency to be surgically simpler to perform, endoscopicall faster to access, easier and with no failure.
BEG, which is a modified biliary reconstruction, facilitates endoscopic access of the biliary anastomosis, offers management option for its complications, and, therefore, could be considered for biliary reconstruction of benign stricture. BEG type III tend to be surgically simpler and endoscopically faster, easier and more successful than type I and II.
