Abstract

Background: Dumping syndrome is a known complication of Roux-en-Y gastric bypass (RYGB). Recently, endoscopic gastrojejunal anastomosis (GJA) revision has been employed as a treatment option. The primary aim of this study was to perform a systematic review and meta-analysis for the role of endoscopic GJA revision in patients with RYGB for the treatment of dumping syndrome. Methods: Search strategies were developed for PubMed, EMBASE, Web of Science, and Cochrane Library databases from inception through December 2020 in accordance with PRISMA and MOOSE guidelines. Pooled proportions with rates estimated using random effects models were used. Outcomes included pooled technical success, clinical success, adverse events, and rate of reintervention. Heterogeneity was assessed with I2 statistics and publication bias by funnel plot using Egger and Begg tests. Results: Six studies (n = 263 patients; 60.25% female) were included (1 prospective and 5 retrospective). Mean age was 46.27 ± 2.54 years. Average patient weight was 95.59 ± 4.78 kg, BMI of 41.43 ± 3.07 kg/m2, and pre-procedure GJA size of 32.23 ± 8.68 mm. Pooled technical and clinical success was 98.15% and 89.5%. Among studies reporting Sigstad scores, endoscopic GJA revision resulted in a significant improvement [mean Sigstad score difference of − 9.96 (95% CI, − 19.951 to − 0.975); P < 0.03]. Mean procedure time was 37.12 ± 10.40 min with an intra-procedural adverse event rate of 2.42%. Over a mean follow-up of 8.03 ± 6.87 months, post-procedure adverse events occurred in 2.96% of patients with a reintervention rate of 11.54%. Conclusion: This systematic review and meta-analysis suggests that endoscopic GJA revision appears an effective and safe treatment for dumping syndrome.
