(HINT: Each PubMedQA instance is composed of (1) a question which is either an existing research article title or derived from one, (2) a context which is the corresponding abstract without its conclusion, (3) a long answer, which is the conclusion of the abstract and, presumably, answers the research question, and (4) a yes/no/maybe answer which summarizes the conclusion.)

Is the covering of the resection margin after distal pancreatectomy advantageous?

[2025-09-25T12:42:41.422750] [PI reasoning] **Evaluating pancreatic surgery outcomes**

I need to provide a yes, no, or maybe answer based on literature, specifically for a PubMedQA-style question. The topic is whether covering the resection margin after distal pancreatectomy reduces the risk of pancreatic fistula. Many studies evaluate different techniques, like stapler closure versus hand-sewn methods, and using patches like falciform ligament or jejunal patches. It’s likely that research indicates covering the margin is beneficial, leading me to lean towards answering "yes." Now, I should quickly look for some relevant studies.
