Sutureless Pancreatojejunal Anastomosis Using an Absorbable Sealant: Evaluation in a Pig Model

BackgroundLeakage from pancreatojejunal anastomosis continues to be a major source of morbidity in pancreatic surgery. In the present study, we test the hypothesis that a safe, sutureless pancreatojejunal anastomosis can be constructed using a synthetic surgical sealant.Materials and methodsTen pigs weighing 20 to 25 kg underwent distal pancreatectomy and anastomosis of the pancreatic remnant with a jejunal limb with the use of an absorbable surgical sealant. Integrity of the anastomosis was checked on the 10th postoperative d by means of an autopsy study and histological examination.ResultsOne animal died on the 3rd postoperative d of peritonitis. The remaining 9 animals had an uneventful postoperative course. Gross and microscopic pathological examination revealed intact pancreatojejunal anastomosis in all surviving animals.ConclusionsFollowing distal pancreatectomy in pigs, pancreatojejunal anastomoses with the use of sealant are technically feasible. During a 10-d observation period, the sealant appeared to prevent anastomotic dehiscence and allow normal anastomotic healing.
