A meta-analysis of the efficacy of Roux-en-Y anastomosis and jejunal interposition after total gastrectomy

Abstract

BackgroundTo compare the clinical efficacy of two alimentary tract reconstruction methods—“P”-shape jejunal interposition (PJI) and Roux-en-Y anastomosis after total gastrectomy.MethodThe following search phrases were utilized to search PubMed, Cochrane Library, Embase, China Academic Journals Network Full-text Database (CNKI), and Wanfang Database as of April 2022: “gastrectomy,” “Roux-en-Y,” “interposition,” “total gastrectomy,” and “jejunal interposition.” Meta-analysis of the operation time, intraoperative blood loss, complication rate, and postoperative nutritional status of patients was performed using RevMan 5.4 software.ResultsA total of 24 studies and 1887 patients were included in the study. Among patients who received a total gastrectomy, the operation time in the PJI group was substantially longer than that in the Roux-en-Y group (WMD = 19.77, 95% CI: 5.84–33.70, P = 0.005). The incidence of postoperative reflux esophagitis in the PJI group was considerably reduced than that in the Roux-en-Y group (OR = 0.39, 95% CI: 0.28–0.56, P < 0.01). The probability of postoperative dumping syndrome in the PJI group was significantly lower than that in the Roux-en-Y group (OR = 0.27, 95% CI: 0.17–0.43, P < 0.01), and the postoperative body mass changes were significantly lower in the PJI group than in the Roux-en-Y group (WMD = 3.94, 95% CI: 2.24–5.64, P < 0.01). The PJI group had substantially higher postoperative hemoglobin, albumin, and total protein levels than the Roux-en-Y group (WMD = 13.94, 95% CI: 7.77–19.20, P < 0.01; WMD = 3.97, 95% CI: 2.58–5.37, P < 0.01; WMD = 5.31, 95% CI: 3.45–7.16, P < 0.01). The prognostic nutritional index was higher in the PJI group than in the Roux-en-Y group (WMD = 9.25, 95% CI: 7.37–11.13, P < 0.01).ConclusionPJI is a safe and effective reconstruction method and is superior to Roux-en-Y anastomosis in the prevention and treatment of postoperative complications and postoperative nutritional recovery in patients after total gastrectomy.
