Background: There is a high risk of anastomotic leakage after pancreaticojejunostomy after pancreaticoduodenectomy (PD) in patients with a normal pancreas because of the high degree of exocrine function. These PD are therefore generally performed using a stenting tube (stented method). In recent years, we have performed pancreaticojejunostomy with duct-to-mucosa anastomosis without a stenting tube (nonstented method) and obtained good results. Methods: The point of this technique is to preserve adequate patency of the pancreatic duct by carefully picking up the pancreatic duct wall with a fine atraumatic needle and monofilament thread. The results of end-to-side pancreaticojejunostomy of the normal pancreas were compared between the nonstented method (n = 109) and the stented method (n = 39). Results: There were no differences in background characteristics between the groups, including age, gender and disease. The mean duration to complete pancreaticojejunostomy was 26.6 min in the nonstented group and 29.2 min in the stented group. The mean durations of surgical procedure and intraoperative blood loss were also similar in the groups. Morbidity rates due to early postoperative complications were 20.2 and 23.1%, with pancreatic leakage occurring in 7.3 and 7.7% of patients, respectively. These differences were not statistically significant. One patient in the stented group died of sepsis following leakage of pancreaticojejunostomy. There were also no significant differences in the mean time to initiation of solid food intake or postoperative hospital stay. Conclusion: We conclude that a stenting tube is unnecessary if the duct-to-mucosa anastomosis is completely performed. This operative technique can be considered a basic procedure for pancreaticojejunostomy because of the low risk.
