Distal pouch reconstruction with transverse jejunoplasty after experimental gastrectomy

Purpose Various reconstruction methods with or without reservoir formation after total gastrectomy have been established. Transverse intestinoplasty has benefits as a functional peristalsis modification in rectal resections. In this study, we evaluate a distal pouch combined with a transverse jejunoplasty compared to standard Roux-en-Y reconstruction. Methods Total gastrectomy was performed on 23 pigs randomly assigned to 3 reconstruction groups—group 1 ( n = 7): esophagojejunostomy without a pouch, group 2 ( n = 8): esophagojejunostomy with a distal pouch, and group 3 ( n = 8): distal pouch with a transverse jejunoplasty. Seven days postoperatively, weight was measured, and X-ray examinations were conducted for 1 h after oral contrast medium application. Blood glucose levels after oral glucose intake and the volume of the pouch loop were evaluated. Results Upper jejunal passage was delayed and the mean volume of the jejunal loop increased by pouch formation compared to controls ( p
