Balloon dilation vs resection: limits of the evidence

What is known

• After EBD, repeat surgical resection is reported in 24–36% of patients at median 5–5.8 years; factors driving long-term outcome are largely unknown. ¹
• EBD durability is limited: cumulative redilatation-free 61.2% and surgery-free 72.6% at 20.5 months, with symptomatic recurrence frequent. ^2,3
• EBD immediate technical success is high (~78%) but symptomatic recurrence requiring new dilation (~41%) or surgery (~42%) is common at ~15 months. ⁴
• Endoscopic strictureplasty/stricturotomy data are also immature, reintervention-free ~60–64% and surgery-free 75–90% at one year, from few small studies. ^2,3

What is unknown / caveats

• No RCT or direct head-to-head EBD vs resection comparison in the retrieved evidence
• Outcome definitions and follow-up durations vary widely, precluding pooled durability estimates
• Prognostic factors for long-term EBD outcome largely uncharacterized
• Whether newer endoscopic electroincision techniques reduce reintervention versus EBD remains unresolved for lack of long-term comparative data.
