title: Long-term symptomatic relief following surgical sphincteroplasty for sphincter of Oddi dysfunction.
abstract: BACKGROUND
  Surgical sphincteroplasty (SS) for sphincter of Oddi dysfunction (SOD) can be performed primarily or following failed endoscopic therapy. The role of SS in an era of endoscopic management is unclear. This study presents long-term follow-up of patients who had undergone SS at a tertiary referral unit.
  
  
  METHODS
  Patients were identified from a departmental database and sent post-operative questionnaires to review pain scores and satisfaction with the procedure. Indications, pre-operative interventions and complications were recorded.
  
  
  RESULTS
  Seventeen patients underwent SS over 13 years. Thirteen patients had objective features of biliary obstruction (delayed excretion of isotope or elevated sphincter pressures). The positive predictive value, sensitivity and specificity of morphine 99mTc-TBIDA in this series was 100, 100 and 92%, respectively. There were 12 responders of whom all but one had symptomatic improvement. Median follow-up was 5.1 years. Pain was significantly lower following SS (16 ± 9 vs. 67 ± 11; p = 0.003) and median satisfaction with the procedure was high (95%).
  
  
  CONCLUSIONS
  Excellent symptomatic pain relief following SS can be achieved in carefully selected patients. Manometry does not appear to be essential for diagnosing SOD and morphine provocation hepatic scintigraphy was used to reliably identify patients who would benefit from SS.
