In symptomatic floppy pouch with recurrent abdominal pain, is endoscopic balloon dilation or laparoscopic pouch revision preferred

the choice depends on the underlying floppy-pouch phenotype and whether a fixed intraluminal stricture is present. endoscopic balloon dilation is reasonable first-line for an intrinsic/intraluminal stricture at the pouch inlet or midpouch and can also give temporary, largely diagnostic relief in afferent limb syndrome (ALS), but the floppy pouch complex, prolapse, ALS, redundant/folding pouch, is fundamentally a mechanical/anatomic problem that is managed predominantly surgically, so a symptomatic floppy pouch refractory to or not suited for dilation typically requires surgical revision (resection of angulated bowel, pouch pexy/mobilization, or redo pouch) ^1–3. ^1–5

What is known: - Endoscopic balloon dilation of ileoanal pouch strictures achieved clinical improvement in ~95% of symptomatic procedures with no major complications and only 1 stricture-related failure over 3 years. ² - In floppy pouch complex, balloon dilation is described as easy to perform and mainly diagnostic. Temporary relief may implicate ALS as the symptom source rather than being durable therapy. ¹ - ALS management is characterized as mainly surgical; in an 18-patient series, repeat dilations were common and some dilation patients ultimately came to pouch excision or surgery, while 8 underwent surgical correction. ^1,3 - Consensus/classification frameworks reserve surgical revision (strictureplasty, resection/reimplantation, redo pouch, or diversion) for cases refractory to repeat endoscopic therapy; midpouch strictures in particular are managed with both dilation and surgical revision. ^3–5

What is unknown / caveats: - No head-to-head trial of balloon dilation vs laparoscopic pouch revision for floppy pouch - Evidence is narrative reviews and single-center retrospective cohorts; floppy-pouch surgical series are small - Retrieved data do not isolate a laparoscopic revision approach specifically or report its comparative outcomes - The corpus does not provide a direct comparison of dilation versus laparoscopic revision, so relative durability and failure rates cannot be quantified from these excerpts.
