Abstract:
Objective:To investigate the impact of body mass index (BMI) on the postoperative complications of open pancreaticoduodenectomy (OPD).Methods:The preoperative, operative and postoperative data of 234 patients who underwent OPD in the Department of the Hepatobiliary and Pancreatic Surgery of First Affiliated Hospital affiliated to Naval Medical University from January 2015 to June 2016 were analyzed retrospectively. According to the Asian BMI standard, the patients were divided into three groups: underweight group (BMI<18.5 kg/m 2, n=32), normal weight group (18.5 kg/m 2≤BMI<23.0 kg/m 2, n=110) and overweight group (BMI≥23.0 kg/m 2, n=92). Normal weight group was compared with underweight group and overweight group, respectively, to analyze the relationship between BMI and intraoperative parameters and major postoperative complications of OPD. Results:The incidence of diabetes in underweight group was lower than that in normal weight group, and the proportion of ASA score 3 in underweight group was higher than that in normal weight group, and there were significantly statistical differences (both P value <0.05). There was no significant difference on the other variables between underweight group, normal weight group and overweight group. The operation time, intraoperative hemorrhage volume >800 ml and intraoperative blood transfusion rate were not statistically different between underweight group and normal weight group, but overweight group had obviously higher intraoperative blood transfusion rate than normal weight group and the difference was statistically significant ( P<0.05). Underweight group had more postoperative intraperitoneal hemorrhage and postoperative blood transfusion rate than normal weight group, and the readmission rate in underweight group was less than that in normal weight group; the incidence of clinically related-post operative pancreatic fistula, postoperative infection, gastrointestinal bleeding and delayed gastric emptying in overweight group were significantly higher than those in normal weight group, and there were significantly statistical differences (all P value <0.05). In underweight group, normal weight group and overweight group, the average length of hospital stay were 9.9 days, 11.3 days, 15 days, and the total hospitalization expenses were 63663.04 yuan, 66241.78 yuan and 80484.31 yuan, respectively. Conclusions:Compared to normal weight patients, the difficulty of OPD in underweight patients does not increase, while the difficulty of OPD in overweight patients increases. Underweight and overweight could both increase the postoperative complications of OPD to some extent.
