Investigating the Risk Factors of Cholelithiasis in Morbid Obese Patients Undergone Bariatric Surgery

Morbid obesity is well-known risk factor of cholelithiasis. On the other hand, rapid weight loss following bariatric surgery, as a treatment of morbid obesity, can cause the formation of gallstones.
In this inquiry we decided to investigate the risk factors of cholelithiasis and evaluate the need for prophylactic cholecystectomy during bariatric surgery.
All desired information of patients with morbid obesity who underwent bariatric surgery during 2011-2017 in surgical ward of Imam Reza hospital of Mashhad were extracted from patient's documents. All data were analyzed using SPSS software.
Totally 150 patients were enrolled in this study from which 127 patients did not have any history of cholelithiasis, 46.5% of patients without any history of cholelithiasis and 73.9% of patients with a history of this condition were positive for gastric H. pylori (p In conclusion in our study the only factor associated with gallstone formation was H. pylori infection. Although H. pylori infection cannot be considered as a concrete reason for prophylactic cholecystectomy merely based on our results, its treatment should be kept in mind as a treatable risk factor of cholelithiasis.
