Effect of end-to-end invagination pancreaticojejunostomy with circle discontinuous U suture in pancreatic surgery

The aim of this paper is to summarize the methods of pancreaticojejunostomy in the pancreatic operation and to study the safety and feasibility of a new operative method called end-to-end invagination pancreaticojejunostomy with circle discontinuous U suture to prevent fistula of pancreaticojejunostomy. Eight-three patients with pancreaticoduodenectomy in the 3rd Hospital, Jilin University from 2001 January to 2006 April were reviewed. The incidences of pancreatic fistula with different types of pancreaticojejunostomy were compared. The overall incidence rate of pancreatic fistula was 26.5% (22/83). No pancreatic fistula occurred in end-to-end invagination pancreaticojejunostomy with circle discontinuous U suture. The incidence rate of the fistula following end-to-end invagination pancreaticojejunostomy with circle discontinuous U suture was significantly lower than that of traditional end-to-end pancreaticojejunostomy 40%, (10/25), P<0.01] and end-to-side pancreaticojejunostomy 27.3%, (12/44), P<0.05], but no significant difference (P>0.05) between traditional end-to-end pancreaticojejunostomy and end-to-side pancreaticojejunostomy was discovered. End-to-end invagination pancreaticojejunostomy with circle discontinuous U suture has a definite effect on avoiding pancreatic fistula following pancreaticojejunostomy and is worth being recommended. But the cases were limited, so this method would still need to be observed and confirmed further in the future.
