title: Are pancreatoenteric anastomoses improved by duct-to-mucosa sutures?
abstract: The patency of anastomoses joining the pancreas to either a Roux-Y loop of jejunum or the stomach was evaluated in 26 dogs. At a preliminary operation, the head and uncinate process of the pancreas were resected while carefully preserving the duodenal blood supply. The remaining body and tail of the pancreas were totally obstructed. After obstruction for a mean of 22 (range: 6 to 42) days, one of three anastomoses was performed: (1) inversion pancreatogastrostomy with two layers of sutures; (2) a similar inversion pancreatojejunostomy to the side of a Roux-Y jejunal loop; or (3) pancreatojejunostomy in which the major duct was joined to the jejunal mucosa with interrupted sutures. Six animals were kept for controls. Anastomotic patency was assessed after 8 to 12 weeks by pancreatography, with minimal pressures to achieve anastomotic flow recorded. Weight trends were consistent with anastomotic status. The eight dogs with duct-to-mucosa sutures clearly achieved superior anastomotic patency.
