AbstractBACKGROUND: Obesity is a major global health problem, and it has reached epidemic proportions worldwide. Therefore, surgeons will confront an increasingly larger proportion of obese candidates for pancreatoduodenectomy (PD) in the future. Several small retrospective studies have been conducted to evaluate the role of Body Mass Index (BMI) in postoperative surgical complications after PD, with conflicting results. The aim of this study was to use a large multi-institutional database to clarify the impact of different levels of obesity after PD. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database was queried for patients who underwent PD from 2014 to 2016. Patients were categorized in the following six BMI groups: <18.5 (Underweight), 18.5-24.9 (Normal Weight), 25-29.9 (Overweight), 30-34.9 (Class I obesity), 35-39.9 (Class II Obesity) and >40 (Class III Obesity). The primary outcomes of interest were 30-day mortality and morbidity after PD among the six BMI groups. RESULTS: The final population consists of 10,316 patients. Class III is associated with higher risk of 30-day mortality (OR 2.56, 95% CI 1.25-5.25, p = 0.011), major complications (OR 2.23, 95% CI 1.54-3.22, p < 0.001), clinically relevant postoperative pancreatic fistula (OR 2.48, 95% CI 1.89-3.24, p < 0.001), surgical site infections (OR 2.06, 95% CI 1.61-2.65, p < 0.001) and wound dehiscence (OR 3.47, 95% CI 1.7-7.1, p < 0.001) in multivariable analysis. CONCLUSIONS: In conclusion, our study shows that obesity is significantly associated with higher risk of postoperative complications in patients undergoing PD and patients with BMI≥40 have increased risk of mortality after PD.
