OBJECTIVE: 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.
SUMMARY BACKGROUND DATA: 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.
PATIENTS AND METHODS: 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.
RESULTS: 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.
CONCLUSIONS: 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.
