BACKGROUND: Pancreatoenteric reconstruction often induces severe complications. Although many techniques have been developed to prevent these complications, no standard technique has yet emerged. We developed a novel technique, sutureless pancreatoenteric anastomosis, that uses a bioabsorbable polymer sheet (BAPS) and biocompatible bond (BCB) to prevent the complications associated with pancreatoenteric anastomosis. We used large animals to investigate whether this technique is suitable for clinical use.
MATERIALS AND METHODS: Six pigs were laparotomized under general anesthesia. The body of the pancreas was divided, and the proximal stump was closed by suture. A BAPS coated with BCB was rolled and fixed around the distal pancreatic stump to form a cylinder that was anastomosed to the duodenum without suturing the pancreas. Twenty weeks after the initial operation the operated sites were extirpated and evaluated grossly and histologically.
RESULTS: All operated pigs survived without pancreatic juice leakage until they were killed. At 20 wk, the BAPS could not be identified. The pancreatic stump was tightly affixed to the duodenum. Histologic study revealed that the pancreatic stump and duodenal wall were continuous and the main pancreatic duct opened into the lumen of the duodenum.
CONCLUSIONS: Sutureless pancreatoenterostomy with BAPS and BCB may be clinically feasible.
