End-to-end anastomosis after medial pancreatectomy for tumor.

Reconstruction by pancreaticoenterostomy has generally been employed after medial pancreatectomy for tumor. As a less invasive procedure, here we report three patients who successfully underwent pancreatic end-to-end anastomosis after medial pancreatectomy. The subjects consisted of 2 patients with serous cystadenomas and 1 patient with an intraductal papillary mucinous tumor. These tumors were detected in the pancreatic neck or body, and the maximal tumor diameters ranged from 10 to 33mm. The pancreatic duct diameters were 2 mm in 2 patients and 4 mm in 1 patient. The procedure was carried out by ductal anastomosis and parenchymal anastomosis with interrupted sutures. A pancreatic tube was inserted for decompression at the anastomotic site in all patients. The mean operative time was 3 hours and 31 minutes, and the intraoperative blood loss was 428 mL. Although pancreatic fistula was observed in 2 patients with the normal pancreas, conservative therapy relieved this complication. Neither tumor relapse nor stenosis of the pancreatic duct at the anastomotic site was detected in any patient, with a follow-up of 4 to 27 months. Our experience confirmed that in selected cases, this reconstructive procedure was feasible and safe for physiological reconstruction without involvement of the digestive tract.
