Objectives. The aim of our study is to identify a surgical technical that has the lowest rate of pancreatic fistulas in pancreatico-gastric anastomosis following duodenopancreatectomies. We studied pancreatico-gastric anastomosis performed with stitches compared to the ones performed without stitches.
Methods. Our experimental model is based on ten piglets, which were divided into 2 groups. In the first group (n=5) the pancreatico-gastric anastomosis was done using double purse-string threads one passed through the gastric seromuscular layer and one through the gastric mucosa. In the second group (n=5) the pancreatico-gastric anastomosis was performed using sutures through the stomach and pancreas.
Results. Postoperative amylasemia was higher in the second group. In the first group no pancreatico-gastric fistulas were observed, whereas pancreatic necrosis was observed only at a superficial level of the pancreatic stump. In the second group, two cases had developed fistulas, both bordered by large areas of coagulation necrosis accompanied by pancreatic duct hyperplasia. Duration of the anastomosis was shorter for the first group.
Conclusions. In conclusion, the pancreatico-gastric anastomosis performed using two purse-string suture is a feasible, safe and fast process.
