description: Surgical patients had a greater risk for undergoing at least 1 additional gastrointestinal surgical procedure (AR, 31.3% vs 15.5%; RD, 15.8% [95% CI, 13.1%-18.5%]; RR, 2.0 [95% CI, 1.7-2.4]).
assertion: Compared with specialized medical treatment, bariatric surgery appears to increase the rate of additional gastrointestinal surgical procedures.
