• Abstract:

  Introduction: Biliary endoscopic sphincterotomy (EST) is a procedure that widens the sphincter of oddi, located in the ampulla of Vater, whose intention is to prevent pancreatic complications in patients unsuitable for cholecystectomy. Objective: To investigate the scientific evidence regarding surgical treatment involving EST in patients with choledocholithiasis, seeking to assess the association of this procedure with the complication of acute pancreatitis in relation to other techniques. Method: Literature review study, between October and November 2022, through the PubMed and Scielo databases, with a total of 13 articles selected after applying criteria. Review: The procedure is characterized by having a resolving and minimally invasive tendency in patients with potential risks of invasive procedures. The presence of hemodynamic instability are obstacles that contraindicate the performance of this surgery. EST has been shown to reduce the risk of recurrence of biliary pancreatitis and has good effectiveness compared to other techniques. Final considerations: EST has the potential to reduce the risk of recurrence of biliary pancreatitis in patients who are not candidates for cholecystectomy.

The presence of hemodynamic instability are obstacles that contraindicate the performance of this surgery. EST has been shown to reduce the risk of recurrence of biliary pancreatitis and to present good effectiveness in comparison with the other techniques. Final Considerations: EST has the potential to reduce the risk of recurrence of biliary pancreatitis in patients who are not candidates for cholecystectomy.
