[Gastric Complications in Stomach-Preserving Procedures on Total Pancreatectomy]

Whether the stomach should be preserved during total pancreatectomy(TP)is controversial. Therefore, we examined the correlation between stomach-preserving procedures on TP and postoperative gastric complications. Seven consecutive cases underwent TP(standard TP: 1 case, SSPTP: 3 cases, PPTP: 3 cases)for pancreatic cancer during the time period 2011-2019 at our hospital. There was no clinical case of postoperative gastric ulcer nor bleeding. Delayed gastric emptying(DGE)was observed in 4 cases of Grade A and 2 cases of Grade C. One of the Grade C cases was considered to be secondary DGE due to postoperative intestinal necrosis. The other was SSPTP case whose left gastric artery(LGA)was ligated. The patient had difficulty of food intake after the surgery and gastrointestinal endoscopy showed widespread hemorrhage and erosion of the gastric mucosa, considered to be ischemic gastropathy. Regarding primary DGE, most of cases were within Grade A even in stomach-preserving cases. Whereas, stomach-preserving procedure should be avoided when the LGA is ligated, because ischemic gastropathy may occur.
