Abstract:
Initial reference search yielded 831 articles. After removing duplicates, 601 articles were evaluated through titles and abstracts. This produced 32 papers suitable for full-text review. Four articles were excluded due to wrong study design, 3 because of the wrong type of intervention, 2 – the lack of primary outcome, 7 were duplicates and 11 were conference abstracts only. Finally, we enrolled 1 RCT and 4 comparative studies with a total of 838 patients, 307 in the LSG + HHR group and 531 in the LSG group (Tab. I.) [5, 10–13]. The flowchart of literature search and study selection is summarized in Fig. 1. 〈 /br 〉 〈 /br 〉 GERD improvement was reported by 5 authors. Fig. 2. shows analysis based on non-event analysis. There were no significant differences between the analyzed studies, 107/171 (62.6%) in HHR+ vs. 78/131 (59.5%) in HHR-, P = 0.74. Heterogeneity between the analyzed studies was moderate, I2 = 66% (Fig. 2.). The “de-novo” GERD was reported in 5 studies. There were no statistically significant differences between the analyzed groups, 26/139 (18.7%) in HHR+ vs. 101/403 (25.1%) in HHR-, P = 0.77. Heterogeneity between the analyzed studies was moderate, I2 = 73% (Fig. 3.).
null Operative time was reported by 3 authors. In all studies, LSG with HHR was significantly longer than LSG alone. When the random effects model was used, the difference between groups was statistically insignificant with heterogeneity of I2 = 98%. Sensitivity analysis showed that the study by Lasnibat is responsible for all heterogeneity. After excluding this study the difference was statistically significant (I2 = 0%, P 〈 0.01). Since all studies showed operative time in favor of LSG, despite high heterogeneity, a fixed effects model was used. 〈 /br 〉 〈 /br 〉 Morbidity was reported in 3 studies. There were no statistically significant differences in any study as well as when the data was pooled, 9/132(6.8%) in LSG +HHR vs. 11/148(7.4%); P = 0.97. The heterogeneity between the studies was low, I2 = 8% (Fig. 5.).
