Benign intrinsic strictures dilate. ASGE 2014 (PMID 24332405) and the BSG/UK guideline (Sami, PMID 29478034) agree on that. TTS balloon and bougie are both acceptable for simple peptic disease. Complex anatomy gets a wire, preferably under fluoroscopy. The rule of 3 is a bougie stop rule after resistance, not a dare. Solid-food relief usually wants a lumen around 15 mm.

Clinical Pearls

  1. Simple short peptic or Schatzki: TTS balloon or bougie. Neither is required over the other.
  2. Complex (long, angulated, caustic, radiation): wire-guided, preferably fluoro. Do not ram a blind bougie down a map you have not seen.
  3. Rule of 3 applies to bougies after you feel resistance: at most three consecutive dilator sizes that session.
  4. PPI after peptic dilation cuts recurrence. Dilation without acid control is a return visit.
  5. EoE rings after you have treated inflammation: EoE page. Malignant colon obstruction is a stent, not a balloon: colon SEMS. LA grade: GERD/LA.

Esophageal Dilation: Balloon or Bougie, Wire for Complex, Target About 15 mm

Simple peptic and Schatzki rings take a balloon or a bougie. Long, twisted, caustic, and radiation strictures take a wire you can see.

Clinical Bottom Line

Stricture How to dilate
Simple peptic or Schatzki TTS CRE balloon or bougie. Visual control with a balloon is convenient. Neither device wins on perforation in simple disease (Sami 2018, PMID 29478034; ASGE 2014, PMID 24332405).
Complex benign Wire through the lumen, confirm in the stomach, preferably fluoroscopy, then bougie or balloon over that wire.
Size target About 15 mm for solid food in most peptic disease. Do not chase 18-20 mm in one sitting on a tight fibrotic stricture.
Stop rule Bougie rule of 3 after resistance. Blood on the dilator is a hint to stop, not a trophy.
Adjuncts PPI for peptic disease. Steroid injection for selected refractory peptic strictures. Stents are salvage after serial dilation fails, not first-line for garden-variety peptic rings.

Balloon or Savary?

A TTS balloon delivers radial force you can watch. A Savary bougie adds a longitudinal shear component and needs the camera out, which is why the wire and, for complex anatomy, fluoroscopy exist. The leftover stub on the companion URL treated Savary as a ramming tool with a perforation destiny. Used over a confirmed gastric wire, it is how radiation and caustic strictures get opened. Used blindly, it is a mediastinal injury.

Pass the smallest dilator that meets resistance, then stop after three size steps. That is the rule of 3. It is expert practice, not an RCT. Ignore it on a 4 mm caustic lumen and you will wish you had not.

What this page will not do

Pneumatic dilation for achalasia is a 30-40 mm balloon aimed at the LES, not a peptic CRE. There is no achalasia permalink in this set. Do not treat this URL as that atlas.

EoE: treat the inflammation, then dilate residual rings if dysphagia remains (ASGE 2014). Dupilumab and diet are the EoE page.

Malignant esophageal obstruction is SEMS palliation, not peptic-style dilation. Malignant colon obstruction is the colon SEMS page. Barrett surveillance is Barrett. LA grading is the GERD page.
