Summary

Biliary sphincter balloon dilation offers comparable success to endoscopic sphincterotomy for small, few gallstones, with potentially fewer complications. However, concerns about pancreatitis risk remain, influencing its routine use.

Area of Science:

  • Gastroenterology and Endoscopy
  • Biliary Tract Interventions

Background:

  • Biliary sphincter balloon dilation was introduced in 1983 and further studied in the early 1990s for gallstone removal.
  • Endoscopic sphincterotomy is a common procedure for biliary stone removal.

Purpose of the Study:

  • To compare the efficacy and safety of biliary sphincter balloon dilation versus endoscopic sphincterotomy for biliary stone removal.
  • To evaluate the role of balloon dilation in specific patient populations.

Main Methods:

  • Review of studies comparing biliary sphincter balloon dilation and endoscopic sphincterotomy.
  • Analysis of success rates for stone removal based on stone number and size.
  • Comparison of complication rates, including pancreatitis.

Main Results:

  • Success rates for stone removal are comparable between balloon dilation and endoscopic sphincterotomy for patients with fewer than three stones (<1 cm).
  • Most studies report fewer complications with balloon dilation compared to endoscopic sphincterotomy.
  • One study indicated a higher incidence of pancreatitis, including severe cases, with balloon dilation.

Conclusions:

  • Biliary sphincter balloon dilation is a viable alternative to endoscopic sphincterotomy for select patients, particularly those with bleeding tendencies or anatomical risks.
  • Hesitancy exists regarding routine adoption due to pancreatitis concerns, necessitating further investigation.
  • The technique is considered a treatment of choice for patients with periampullary diverticula or post-Billroth II gastrectomy.
