To compare the effect of RYGB and OAGB on patients after failed treatment obesity by laparoscopic sleeve gastrectomy (LSG). A case–control study based a prospectively maintained database reoperated LSG, which included 33 who underwent conversion 47 conversion. The mean %EBWL 5-year follow-up for RYGBc vs OAGBc was 84.04% 72.95% (p = 0.2176), respectively. Complete long-term diabetes remission observed significantly more frequently in than group (97.3% 33%; p 0.035). There were no other statistically significant differences rate comorbidities between OAGBc: hypertension 30% 27.3% 0.261), dyslipidemia 83.3% 59.1% 0.277), OSAS 100% 60% 0.639), GERD 40% 71.4% > 0.99), 7 newly diagnosed with none RYGBc. number complications groups. Comprehensive Complication Index 17.85 (± IQR 29.6) 14.92 21.75) 0.375). authors recognized complete type 2 surgery as most relevant difference, where variety found superior its better efficacy. Any consequences both procedures used failure LSG have not been stated. Both methods therefore can be considered to initial treatment, considering preferences individual burdens patients.
