Hypothesis
Can sphincter of Oddi manometry be performed safely and effectively in low-volume centers?
Conclusion
Sphincter of Oddi manometry can be performed successfully and safely in low volumes with results comparable to larger centers.
Supporting Evidence
- 90% of type II SOD patients with elevated basal sphincter pressures improved after sphincterotomy.
- Only 43% of type II SOD patients with normal pressures improved after sphincterotomy.
- 16% of patients experienced procedure-related complications, mostly mild.
Takeaway
Doctors can do a special test called sphincter of Oddi manometry safely even if they don't do it very often, and it can help some patients feel better.
Methodology
Retrospective analysis of patient records from a tertiary care hospital reviewing procedural details, outcomes, and complications.
Potential Biases
Outcomes based on patient perception of symptom improvement, which may be influenced by placebo effects.
Limitations
Small patient population and lack of follow-up for some patients.
Participant Demographics
Mean age of 41 years, 84% female, with 64% classified as type II SOD and 36% as type III SOD.
