Organ-Sparing Pancreatectomy for Benign or Low-Grade Malignant Pancreatic Tumors: A Single-Center Experience with 101 Consecutive Patients

Background: Pancreaticoduodenectomy (PD) and distal pancreatectomy with splenectomy (DPS) are considered the standard procedures for pancreatic lesions. However, long-term metabolic consequences of PD and DPS applied for benign or low-grade malignant tumors need to be addressed. This study aimed to investigate the short- and long-term outcomes of organ-sparing pancreatectomy for benign or low-grade malignant pancreatic tumors in our institution. Material/Methods: The clinical data of 101 patients with benign or low-grade malignant pancreatic tumors who underwent organ-sparing pancreatectomy from January 2009 to September 2021 were retrospectively analyzed, including 40 tumor enucleations (EN), 22 central pancreatectomies (CP), 25 spleen-preserving distal pancreatectomies (SPDP), 7 pylorus-preserving pancreaticoduodenectomies (PPPD) and 7 duodenum-preserving pancreatic head resections (DPPHR). Results: The mean operative time, intraoperative blood loss, and length of hospital stay were 182.9 +/- 74.6 min, 191.9 +/- 127.8 mL, and 11.6 +/- 8.1 days, respectively. EN had the shortest operative time, while DPPHR had the longest operative time. The mean intraoperative blood loss of DPPHR and PPPD was significantly greater than the others (all P<0.05). The length of hospital stay of PPPD was longest. The overall morbidity was 33.6%. The reoperation rate was 1.0% and there was no mortality. The incidence of pancreatic endocrine insufficiency and exocrine insufficiency were 5.9% and 6.9%, respectively. None patients had tumor recurrence during the follow-up period Conclusions: Organ-sparing pancreatectomy is associated with acceptable perioperative risk and postoperative complications and better long-term outcomes in the aspects of preservation of function and curability in benign or low-grade malignant pancreatic tumors

Automated summary

This study retrospectively analyzed the clinical data of 101 patients who underwent organ-sparing pancreatectomy and found that this surgical technique is associated with acceptable perioperative risk and postoperative complications, as well as better long-term outcomes in benign or low-grade malignant pancreatic tumors.
