BackgroundPalliative efficacy of conventional gastrojejunostomy in palliation of malignant gastric outlet obstruction is debatable. This study aims to compare the outcomes of conventional gastrojejunostomy and stomach-partitioning gastrojejunostomy and to explore the factors influencing the delayed gastric emptying after surgery in patients with malignant gastric outlet obstruction.MethodsThe study subjects were divided into the following two groups based on whether the stomach was partitioned or not: Conventional gastrojejunostomy and stomach-partitioning gastrojejunostomy. All demographic data, patient characteristics, postoperative outcomes, including delayed gastric emptying grade and 30-day complications were collected. Following the comparison of the clinical outcomes, risk factors for delayed gastric emptying were determined by regression models.ResultsFifty-three patients were included in this study. Of these, 37 patients underwent conventional gastrojejunostomy, whereas 16 patients underwent stomach-partitioning gastrojejunostomy. Patient demographics and baseline characteristics were comparable between groups. Although 10 (27%) patients in the conventional gastrojejunostomy group had delayed gastric emptying grade B-C, no patient in the stomach-partitioning gastrojejunostomy group experienced this condition. There was no difference between the groups concerning hospital stay and complications. In multivariate regression analysis, having distant metastasis (OR=0.156, 95%CI 0.034-0.720, p=0.017) and stomach-partitioning (OR=0.127, 95%CI 0.025-0.653, p=0.014) were found as independent factors for the delayed gastric emptying.ConclusionIn patients with malignant gastric outlet obstruction, compared with conventional gastrojejunostomy, stomach-partitioning may provide favorable clinical outcomes by improving gastric emptying.
