  • Title: Intestinalization of pancreatic fragments in dogs.
    Author: Senninger N, Moody FG, Van Buren DH, Coelho JC.
    Journal: Surg Gynecol Obstet; 1986 Apr; 162(4):355-60. PubMed ID: 2421423.
    Abstract:
    A new operative procedure for the preservation of pancreatic fragments is introduced ("intestinalization") in which vascularized fragments are placed inside a jejunal pouch. This step is done to manage all secretions, lymph and potential debris coming from the pancreas; to maintain the primary portal drainage of insulin; to avoid vascular operations, and to keep the fragment in a denervated state and still preserve its endocrine function to prevent diabetes. The procedure was compared with conventional end to end pancreaticojejunostomy. Sixteen dogs were studied. Group 1 consisted of four dogs that had intestinalization of the pancreatic tail. Group 2 is made up of eight dogs that had complete resection of the remaining duodenal portion of the gland as well as intestinalization of the pancreatic tail. Group 3 consisted of four dogs that had end to end pancreaticojejunostomy to the isolated tail and complete resection of the duodenal portion of the gland as those dogs in group 2. No dog became diabetic during the time of observation (up to one year)--fasting glucose levels and K values in glucose tolerance tests remained normal. Insulin peak values at ten minutes were lower postoperatively. However, return to fasting levels occurred equally fast postoperatively. There was no difference among the groups. The most important morphologic finding in the intestinalized fragments was a firm capsule surrounding the tissue after two weeks. Exocrine atrophy was present in both groups 2 and 3 after one year. No reinnervation of intestinalized pancreas was seen. Intestinalization may offer an alternative to pancreatic resection especially when heterotopic autotransplantation is considered.
