Abstract
Background
Standard pancreatic resections (SPRs) might have long-term deleterious effects on pancreatic function, without added oncological advantage in low malignant potential (LMP) or benign neoplasms. This study aimed to evaluate outcomes following organ-preserving pancreatic resections (OPPARs) and SPRs.
Method
Post hoc analysis of patients undergoing OPPAR or SPR for benign or LMP pancreatic tumors from January 2011 to January 2020 at Tata Memorial Hospital, Mumbai.
Results
Thirty-six and 114 patients were identified in OPPAR and SPR groups respectively. The overall morbidity (58.3% vs 43.9%, p-0.129) was comparable. Major morbidity (41.7% vs 21.9%, p-0.020), post-operative pancreatic fistula (POPF) (63.9% vs 35.1%, p-0.002), and clinically relevant POPF (41.7% vs 20.2%, p-0.010) were significantly higher with OPPAR. Post-operative endocrine insufficiency (14.9% vs 11.1%, p-0.567), exocrine insufficiency (19.3% vs 0%, p-0.004), and requirement of long-term pancreatic enzyme replacement (17.5% vs 0%, p-0.007) were higher in SPRs. Comparing left-sided and right-sided resections in the entire cohort, incidence of endocrine insufficiency was 17.1% vs 11.2% (p-0.299) and that of exocrine insufficiency was 8.6% vs 20% (p-0.048) respectively.
Conclusion
OPPAR is associated with high post-operative major morbidity and pancreatic fistula rate but offers long-term benefit due to better preservation of pancreatic function than SPR. The incidence of exocrine insufficiency is higher in right sided as compared to left-sided pancreatic resections.
