Abstract | BACKGROUND: The life-threatening complications following pancreatoduodenectomy (PD), intra-abdominal hemorrhage, and postoperative infection, are associated with leaks from the anastomosis of pancreaticoduodenectomy. Although several methods have attempted to reduce the postoperative pancreatic fistula (POPF) rate after PD, few have been considered effective. The safety and short-term clinical benefits of omental interposition remain controversial. AIM: To investigate the safety and feasibility of omental interposition to reduce the POPF rate and related complications in pancreaticoduodenectomy. METHODS: In total, 196 consecutive patients underwent PD performed by the same surgical team. The patients were divided into two groups: An omental interposition group (127, 64.8%) and a non-omental interposition group (69, 35.2%). Propensity score-matched (PSM) analyses were performed to compare the severe complication rates and mortality between the two groups. RESULTS: Following PSM, the clinically relevant POPF (CR-POPF, 10.1% vs 24.6%; P = 0.025) and delayed postpancreatectomy hemorrhage (1.4% vs 11.6%; P = 0.016) rates were significantly lower in the omental interposition group. The omental interposition technique was associated with a shorter time to resume food intake (7 d vs 8 d; P = 0.048) and shorter hospitalization period (16 d vs 21 d; P = 0.031). Multivariate analyses showed that a high body mass index, nonapplication of omental interposition, and a main pancreatic duct diameter < 3 mm were independent risk factors for CR-POPF. CONCLUSION: The application of omental interposition is an effective and safe approach to reduce the CR-POPF rate and related complications after PD.
