Core Tip

Core Tip: Routine intraoperative drain placement after pancreatic surgery increases the risk of clinically relevant postoperative pancreatic fistula (CR-POPF) and delayed gastric emptying. Patients without drains had lower morbidity, readmission rates, and reoperations. The necessity of routine drain placement is questionable. No clear recommendation can be made between active suction and passive gravity drainage methods. Early drain removal is supported to reduce the occurrence of CR-POPF and associated morbidity and mortality.
