The study effect of Bariatric Surgery on Bile Salt Metabolism and Gallstone Formation: Risk Factors, Preventive Strategies, and Clinical Implications

Abstract

Bariatric surgery is seen as a safe and functional treatment for fatness and its associated comorbid conditions. Also, nevertheless, it is linked with an increased risk of gallstone formation. The risk factor is believed to be due to perturbation of bile salt equilibrium, rapid weight loss, and alteration in the composition of bile. Bile salt metabolism differences are compared between five common bariatric operations (sleeve gastrectomy (SG), Roux end Y gastric bypass (RYGB), mini gastric bypass (MGB), single anastomosis sleeve ileal bypass (SASI), and single anastomosis sleeve jejunal bypass (SASJ)) and to what degree these differences might contribute to gallstones.

The results demonstrate that procedures that bypass the duodenum, jejunum, or ileum  (RYGB,  MGB,  SASI,  SASJ)  have  serious  consequences  on  bile  salt reabsorption,  contributing  to  high  cholesterol  supersaturation  and  creation  of gallstones. SG from a bile salt perspective had the least direct impact; however, the rapid  weight  loss  occurring  postoperatively  also  created  a  moderate  risk  of gallstone formation. Treatment strategies such as ursodeoxycholic acid (UDCA) therapy scheduled intervals post-surgery combined with gradual weight loss and dietary changes and considerations were effectively utilized in decreasing gallstone formation.

This  paper  illuminated  the  need  for  individualized  treatment  approaches  for procedures that are associated with greater post-operative risk RYGB or MGB procedures.  Prompt  interventions  and  timely  prescribed  medications  and monitoring are critical in the care of these patients to realize better outcomes and have less post-operative complications.
