Benign stricture of bilioenteric anastomosis after Whipple with synthetic polypropylene suture

To the Editor: Biliary stricture formation at the bilioenteric anastomosis is an infrequent complication(2％-3％)after pancreaticoduodenectomy;the average presentation is within 13-14 months(range from 1 month to 9 years)after surgery[1,2].While the etiology is un-known,development of biliary stricture has shown to be more likely if a bile leak occurs in the postoperative period[3,4]and with younger patients[5].
