LASNIBAT R, Juan Pablo et al. Cholelithiasis in obese patients undergoing bariatric surgery: 12-month postoperatively study and monitoring. Rev Chil Cir [online]. 2017, vol.69, n.1, pp.49-52. ISSN 0718-4026.  http://dx.doi.org/10.1016/j.rchic.2016.07.007.

Introduction: Chile is known for being one of the countries with higher prevalence of gallstone disease in the world. Among the risk factors for biliary pathology are female gender, age, overweight and obesity. These factors associated with rapid weight loss are characteristic of obese patients undergoing bariatric surgery. It has been reported that patients undergoing these surgeries have a high incidence of cholelithiasis to 12 months postoperatively. Objectives: To determine the prevalence of gallstone disease in obese patients undergoing bariatric surgery, and analyze the occurrence of this disease during the postoperative follow-up up to 12 months. Material and methods: Retrospective case series including 221 patients undergoing bariatric surgery, with follow-up up to 12 months. Review of clinical records and abdominal ultrasound was conducted. Results: A 18.09% of patients had a history of previous cholecystectomy. A 13.57% of patients had preoperative cholelithiasis and a concomitant cholecystectomy was performed in all of them. Follow up was conducted in 151 patients. In ultrasound examinations at one year, 3.54% had cholelithiasis. Conclusions: There is a high prevalence of cholelithiasis in the population undergoing bariatric surgery. The emergence of this disease in the first year was lower than that reported in the literature. Patients should be closely monitored for the detection of this disease during the first postoperative year.
