Stricturing gastric CD: dilation or surgical bypass

What is known

• EBD is an effective alternative to surgery for endoscopically accessible strictures shorter than ~4 – 5 cm and is preferred initial modality; active inflammation alone is not a contraindication, though deep ulceration or suspected malignancy argues against dilation. ¹
• EBD is first-line for non-complex, single, short (<4–5 cm) strictures without pre-stenotic dilation; endoscopic stricturotomy/strictureplasty or surgery follow if EBD fails. ²
• In a series of upper-GI Crohn's strictures (mostly duodenal) treated by EBD, 62.5% avoided surgery over ~20 months but only 25% resumed normal diets, and recurrent symptoms often required repeat dilation. ^3,4
• ECCO/ESCP surgical options for stomach-to-jejunum Crohn's include distal gastrectomy, Roux-en-Y gastrojejunostomy (bypass), and strictureplasty; bowel length should be conserved. ⁵
• A 2025 systematic review with network meta-analysis reported bypass had lower treatment failure than strictureplasty in duodenal Crohn's disease. ⁶

What is unknown / caveats

• Retrieved evidence is on duodenal/esophageal Crohn's; no chunk isolates a purely gastric stricture
• The 2025 meta-analysis compares bypass vs strictureplasty, not bypass vs EBD
• No head-to-head EBD-vs-bypass trial in this evidence directly resolves the choice for gastric disease with dysphagia.
