Duodenum-preserving total pancreatic head resection for cystic neoplastic lesions in the head of the pancreas

Abstract

Cystic neoplastic lesions of the pancreas are now found with increasing frequency. Duodenum-preserving pancreatic head resection with segmental resection of the duodenum has been introduced for the surgical treatment of inflammatory and neoplastic lesions. We report the following data from 15 patients treated surgically for cystic neoplastic lesions of the pancreas head. Duodenum-preserving total pancreatic head resection (DPPHRt) with segmental resection of the duodenum (SD) was performed in eight patients, five with intraductal papillary mucinous neoplasm (IPMN), two with mucinous cystic neoplasm (MCN), and one with cystic endocrine neoplasm (EN). In four patients, a subtotal pancreatic head resection was performed, but recurrence of the IPMN lesion was observed in two patients. Ten patients suffered cystadenoma, three patients had a borderline lesion, and two patients had an in-situ carcinoma. Eight patients had a DPPHRt with SD resection, two patients had a resection of the uncinate process including segmental resection of the inferior duodenal segment, and one patient had a duodenum-and spleen-preserving total pancreatectomy. In four patients a DPPHR with subtotal pancreatic head resection was carried out. Postoperative local complications occurred in eight patients: there was a recurrence of the IPMN lesion in the remnant pancreatic head in two patients; and there was intraabdominal bleeding in one patient, pancreatic fistula in one patient, and delay of gastric emptying in four patients. Seven patients showed signs of acute pancreatitis. Hospital mortality was 0%, and postoperative length of hospital stay was 10. 4 days (range, 8-18 days). Duodenum-preserving total pancreatic head resection for IPMN, MCN, serous cystadenoma (SCA), and cystic EN lesions is a safe and beneficial surgical procedure. Segmental resection of the duodenum was applied for an oncologically complete resection. In regard to long-term outcome, the procedure is, additionally, a pancreatic cancer preventive strategy.
