Pancreaticojejunostomy using duct-to-mucosa anastomosis without a stenting tube

Background Purpose. There is a high risk of anastomotic leakage after pancreaticojejunostomy following pancreaticoduodenectomy in patients with a normal soft pancreas because of the high degree of exocrine function. Therefore, pancreaticojejunostomy is generally performed using a stenting tube (stented method). However, pancreaticojejunostomy with a certain duct-to-mucosa anastomosis does not always require a stenting tube, even in patients with a normal soft pancreas. Recently, 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 maintain adequate patency of the anastomosis using a fine atraumatic needle and monofilament thread. The results of end-to-side pancreaticojejunostomy of the normal soft pancreas using the nonstented method (n = 123) were compared with those using the stented method (n = 45). Results. There were no differences in background characteristics between the groups, including age, gender, and disease. The mean times to complete pancreaticojejunostomy were around 30 min in the two groups and the rates of morbidity and leakage of pancreaticojejunostomy were 26.8% and 5.7% in the nonstented group and 22.2% and 6.7% in the stented group, 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. Conclusions. In conclusion, complete pancreaticojejunostomy using duct-to-mucosa anastomosis for a normal soft pancreas does not require a stenting tube. This nonstented method can be considered one of the basic procedures for pancreaticojejunostomy because of its safety and certainty.
