Failed duodenal dilation: repeat dilation or surgery

What is known

• In a gastroduodenal CD IPD meta-analysis, all second and third dilations were technically successful, with clinical success of 85% (second) and 88.9% (third); re-dilation was needed in 61.6% of patients. ¹
• EBD is an appropriate surgery-sparing first-line option for short, accessible, non-penetrating strictures but carries a high need for repeat dilation over time. ²
• A retrospective comparison found surgery gave greater symptomatic improvement (100% vs 63.3%) and longer recurrence-free survival (median 6.31 vs 2.96 years) than EBD, but with more adverse events. ²
• EBD complications are uncommon (perforation, bleeding ~2-5%); the two perforations in one cohort occurred at the first dilation in strictures <5 cm. ^1–3

What is unknown / caveats

• EBD-favoring series emphasize surgery-sparing and low risk ^4,5; a comparative study favors surgery for durability of symptom control ²
• No retrieved study specifically compares repeat dilation vs surgery restricted to patients who already failed an initial dilation
• EBD suitability is limited to straight, non-angulated strictures up to ~5 cm and within endoscopic reach; deep ulceration or suspected malignancy argue against it
• Comparative data are retrospective, not randomized
• The evidence does not establish which approach is superior specifically after a failed index dilation.
