Middle segmental pancreatic resection: An option to treat benign pancreatic body lesions.

Abstract

To clarify whether middle segmental pancreatic resection can be performed with comparable morbidity and mortality to classic pancreatic resections for lesions in the mid-portion of the pancreas. Pancreaticoduodenectomies or distal pancreatectomy, traditionally used to treat lesions of the pancreatic body, sacrifice a significant amount of normal pancreatic tissue. Middle segmental pancreatic resection has therefore been introduced to minimize loss of functioning pancreatic tissue. In a prospective 4-year single-center study, 40 consecutive patients with lesions of the neck or the body of the pancreas underwent a middle segmental pancreatic resection. A matched-pairs analysis comparing middle segmental pancreatic resection with pp-Whipple and distal pancreatectomy was included. Seventeen patients had neoplastic lesions (4 solid malignancies, 9 cystic lesions, 4 neuroendocrine tumors) and 23 patients had focal chronic pancreatitis. Postoperative surgical morbidity was 27.5% and mortality 2.5%. The reoperation rate was 5.0%. Three patients (7.5%) developed pancreatic fistula. Median postoperative hospital stay was 11 days (range, 6-62 days). After a median follow-up of 29 months, 97.4% (38 patients) of the patients were satisfied with the operation. The mean quality of life status (EORTC QLQ-C30) was comparable to a normal control population. Matched-pairs analysis revealed no differences of perioperative parameters (except operation time), morbidity, and mortality. However, endocrine pancreatic function was better preserved (P < 0.05) in patients with middle segmental pancreatic resection. Middle segmental pancreatic resection is an appropriate procedure for selected patients with tumorous lesions in the mid-portion of the pancreas. It preserves pancreatic parenchyma and function and has a mortality and morbidity rate comparable to other pancreatic resection procedures.
