Sphincterotomy effectively treats biliary sphincter of Oddi dysfunction in patients with high basal pressure. However, it offers no benefit over placebo for those with normal basal pressure, indicating a need for further research.

Area of Science:

  • Gastroenterology
  • Surgical Gastroenterology
  • Biliary System Physiology

Background:

  • The sphincter of Oddi controls bile and pancreatic juice flow into the duodenum.
  • Dysfunction can lead to biliary or pancreatic duct issues, commonly causing post-cholecystectomy pain.
  • Biliary sphincter of Oddi dysfunction (BSOD) presents as recurrent biliary pain.

Purpose of the Study:

  • To evaluate the effectiveness of sphincterotomy as a treatment for biliary sphincter of Oddi dysfunction.
  • To determine if sphincterotomy improves symptoms in patients with BSOD.

Main Methods:

  • Systematic review and meta-analysis of randomized placebo-controlled trials.
  • Searched multiple databases (MEDLINE, EMBASE) for studies on sphincter of Oddi dysfunction and sphincterotomy.

  • Included trials using manometry to assess basal pressure (>40 mmHg defined as abnormal).

    • Main Results:

    • Two randomized trials (49 patients) showed sphincterotomy was more effective than placebo for elevated basal pressure (Peto OR 9.08).
    • Sphincterotomy was not better than placebo in patients with normal basal pressure (77 patients, Peto OR 1.28).
    • No data on quality of life or health economics was available.

    Conclusions:

    • Sphincterotomy is effective for BSOD in patients with elevated basal pressure (>40 mmHg).
    • It is not superior to placebo for patients with normal basal pressure.
    • Results should be interpreted cautiously due to limited studies and potential reviewer bias; independent trials are recommended.
