Background Postoperative pancreatic fistula (POPF) is a potentially lethal complication of pancreatic surgery. POPF rate is consistently higher after distal pancreatectomy (DP) compared with pancreatoduodenectomy (PD). The acinar score of the remnant pancreas is associated with postoperative pancreatitis and POPF. This study aimed to: (i) confirm the difference in POPF rate after DP vs PD; (ii) confirm the association between acinar score and POPF; and (iii) evaluate the difference in acinar scores between DP and PD. Methods Patients undergoing DP or PD at a single institution from 2011 to 2017 were included. Hematoxylin and eosin‐stained slides of the pancreatic resection margin were evaluated for all patients and scored for acinar cell density. Clinicopathological data were retrieved from a prospectively maintained database. Results Two hundred and ninety‐four patients were included in the analysis (206 PD, 88 DP). The POPF rate was significantly higher after DP than PD (20.4% vs 11.2%, P = .043). Acinar score >50 was independently associated with the development of POPF (OR 6.457, P = .003). DP was associated with a higher median acinar score than PD (65 vs 50, P < .001). Conclusion The POPF rate is significantly higher after DP compared with PD and is attributable to a higher acinar score of the pancreatic resection margin.
