Effect Of Braun Anastomosis On Delayed Gastric Emptying After Pancreaticoduodenectomy

Aims: To investigate the effect of Braun anastomosis on gastric emptying delay after pancreaticoduodenectomy.Methods: A retrospective analysis of the clinical data of 132 patients who underwent pancreaticoduodenectomy in the First Hospital of Lanzhou University from Dec.2016 to Dec.2019.They were classified as BE according to whether they performed BE during the operation.Group and non-BE group.The postoperative gastric emptying delay,pancreatic fistula,biliary fistula and other complications,intraoperative conditions,general examination indicators,postoperative treatment and recovery,and overall hospitalization were compared between the two groups.The comparison of measurement data between the two groups that meets the normal distribution uses the t test,the comparison between the two groups that does not meet the normal distribution uses the Mann-Whitney U test,and the comparison of the count data between the two groups uses the χ2 test and Fisher’s exact test.To evaluate the effect of BE on the prevention of DGE after PD.Results: In overall comparison,the incidence of grade C DGE after PD in BE group was significantly lower than that in non-BE group(P<0.05).In different pathological subgroups: pancreatic malignancies、bile duct malignancies、duodenal malignancies、benign duodenal diseases,among the above four groups,the incidence of grade C DGE after PD in the BE group decreased,but it was not statistically significant(P>0.05).Single confounding factor group comparison: bile duct group、duodenum group、pancreatic group、malignant tumors、benign tumors,in the above five groups,the incidence of grade C DGE after PD in the BE group was reduced,but it was not statistically significant(P>0.05),and pathological confounding was completely ruled out The comparison results of factor subgroups are consistent.Conclusion: 1.Braun anastomosis can reduce the incidence of grade C DGE after PD,but the effect is not significant;2.The occurrence of DGE after PD was not significantly related to the pathological type.
