Roux-en-Y versus Billroth I reconstruction after distal gastrectomy for gastric cancer: A meta-analysis

Figure 1 Flow diagram depicting the process of identification and inclusion of selected studies.

Figure 2 Roux-en-Y versus Billroth I-randomized controlled trials comparison. A: Operation time; B: Intraoperative blood loss; C: Hospital stay; D: Anastomotic leakage; E: Anastomotic stricture; F: Bile reflux; G: Remnant gastritis; H: Reflux esophagitis; I: Delayed gastric emptying. Pooled weighted mean difference (WMD) or odds ratio (OR) with 95%CI was calculated using the fixed-or random effects model.

Figure 3 Roux-en-Y versus Billroth I-observational non-randomized clinical studie comparison. A: Operation time; B: Intraoperative blood loss; C: Hospital stay; D: Anastomotic leakage; E: Anastomotic stricture; F: Bile reflux; G: Remnant gastritis; H: Reflux esophagitis; I: Dumping symptoms; J: Delayed gastric emptying. Pooled weighted mean difference (WMD) or odds ratio (OR) with 95%CI was calculated using the fixed-or random effects model.

Figure 4 Funnel plot. A: Operation time-randomized controlled trial; B: Remnant gastritis-observational clinical studies. None of the studies lay outside the limits of the 95%CIs, and there was no evidence of publication bias.
