Safety and Efficacy of Bariatric Surgery in Cirrhosis Patients With Extreme Obesity.

Abstract

To assess the safety and efficacy of bariatric surgery in patients with cirrhosis. Bariatric surgery may be a viable option for patients with cirrhosis and extreme obesity. However, the risk of liver decompensation after surgery is not thoroughly investigated. We conducted a case-controlled study with 106 obese patients with cirrhosis (cases) and 317 age, sex, body mass index-, and type of surgery-matched obese patients without cirrhosis (controls) who underwent bariatric surgery. Patients with cirrhosis were predominantly Child-Pugh class A (97%) with the diagnosis established prior to surgery in only 46%. In the cirrhosis group, there was no death in the first 30 days compared with 1 patient in the control group. At 90 days there was 1 death in the cirrhosis group but no additional deaths in the control group. In total, 12 months after the surgery, there were 3 deaths in the cirrhosis group and 1 in the control group (2.8% vs 0.6%, P = 0.056). The surgery-related length of stay was significantly longer in patients with cirrhosis (3.7 ± 4.0 vs 2.6 ± 2.4 d, P = 0.001), but the 30-day readmission rate was lower (7.5% vs 11.9%, P = 0.001). The percent of total weight loss at 30 and 90-days was not significantly different between the groups and remained that way even at 1 year (29.1 ± 10.9 vs 31.2 ± 9.4%, P = 0.096). Bariatric surgery in obese cirrhotic patients is not associated with excessive mortality compared with noncirrhotic obese patients.
