Symptom relief after one dilation of a duodenal stricture

What is known

• A benign duodenal stenosis cohort (n=86, all etiologies) reported 97.4% technical and 77.8% clinical success after balloon dilatation. ¹
• Fluoroscopically guided dilation of benign duodenal strictures was technically and clinically successful in 7/8 (88%) patients, though re-dilation/surgery for recurrence occurred. ²
• EBD for accessible non-penetrating strictures gives moderate short-term clinical efficacy (~70–80%) but a high need for repeat dilations over time. ³
• Benign GOO series required 1–6 sessions (mean 2.2), indicating single-session relief is not the norm. ⁴

What is unknown / caveats

• Reported figures are per-cohort/per-course clinical success, not per-first-session relief
• Several series pool mixed etiologies and Crohn's-specific duodenal data are small (case reports/small cohorts)
• The excerpts do not isolate the proportion achieving relief after a single dilation session.
