Abstract

Abstract: Background: The conventional Billroth I anastomosis (cBIA) after laparoscopic distal gastrectomy (LDG) is performed through circular staple extracorporeally. Now, delta-shaped anastomosis (DA), which is performed using a linear stapler intracorporeally, becomes popular. We conducted a meta-analysis to compare the effectiveness and safety between the 2 techniques. Methods: A systematic literature search was performed using PubMed, Ovid, and the Cochrane Library Central. Participants of any age and sex, who underwent DA, or cBIA after LDG, were considered following inclusion criteria. Results: A total of 11 articles, published between 2010 and 2017, fulfilled the selection criteria. The total sample size of these studies was 2729 cases, including DA group 1008 cases and cBIA group 1721 cases. Compared to cBIA group, patients in DA group had less blood loss (mean deviation [MD] = −0.68, 95% confidence interval [CI] = −0.15 to −0.31, P < .001), fewer administration of analgesics (MD = −0.82, 95% CI = −1.58 to −0.05, P = .04), lower NRS score on POD 1 (MD = −0.84, 95% CI = −1.34 to −0.33, P = .001), lower NRS score on POD 3 (MD = −0.38, 95% CI = −0.50 to −0.26, P < .001). Furthermore, compared to cBIA group, obese patients in DA group had fewer total number of complications (MD = 0.46, 95% CI = 0.22 to 0.95, P = .04), shorter postoperative hospital stays (MD = −0.73, 95% CI = −1.18 to −0.28, P = .001), earlier first flatus (MD = −0.30, 95% CI = −0.50 to −0.10, P = .004), fewer administration of analgesics (MD = −1.08, 95% CI = −1.61 to −0.55, P < .001), lower NRS score on POD 1 (MD = −0.68, 95% CI = −0.99 to −0.37, P < .001) and lower NRS score on POD 3 (MD = −0.63, 95% CI = −0.86 to −0.40, P < .001). Conclusions: Compared with cBIA, DA is a safe and feasible procedure, with similar surgical outcomes and postoperative complications. In terms of postoperative recovery, DA is less invasive with quicker resume than cBIA, especially for the obese patients.
