Treatment for Esophageal Stricture Causing GERD
The primary treatment for esophageal stricture secondary to GERD is endoscopic dilation combined with high-dose proton pump inhibitor (PPI) therapy to prevent recurrence. 1
Initial Management Strategy
PPI Therapy as Foundation
- Initiate high-dose PPI therapy immediately for all patients with GERD-related strictures, as this reduces the need for initial dilation and prevents stricture recurrence after dilation. 1
- Use omeprazole 20 mg or lansoprazole 30 mg once daily, taken 30-60 minutes before the first meal, escalating to twice-daily dosing if needed. 2
- PPIs are superior to H2-receptor antagonists, which are ineffective in reducing repeat dilation requirements and less effective for healing esophagitis. 1
Endoscopic Dilation Protocol
- Perform graded endoscopic dilation using bougie or balloon dilators to achieve a target diameter of ≥15 mm. 1
- Use weekly or two-weekly dilation sessions until easy passage of a ≥15 mm dilator is achieved with symptomatic improvement. 1
- A stepwise approach to 13-20 mm provides good relief in 85-93% of peptic stricture cases. 1
Management of Refractory Strictures
A stricture is considered refractory when unable to maintain a luminal diameter of ≥14 mm after five sequential dilations 1-2 weeks apart, or unable to maintain target diameter for 4 weeks once achieved. 1
Before Declaring Refractory Status
- Ensure optimal management of ongoing inflammation with high-dose PPI therapy before redefining a stricture as refractory—this is critical as inadequate acid suppression is a common pitfall. 1
- Consider alternative neuromuscular causes (achalasia, esophageal dysmotility) in patients with ongoing dysphagia despite seemingly adequate esophageal diameter. 1
Advanced Treatment Options for Refractory Cases
Intralesional Steroid Therapy:
- Use intralesional triamcinolone (0.5 mL aliquots of 40 mg/mL to all four quadrants) combined with dilation in refractory strictures with evidence of inflammation, assuming anti-reflux therapy has been maximized. 1
- This approach reduces the number of repeat dilations and increases the dysphagia-free period for peptic strictures specifically. 1
- Note: This is less effective for anastomotic or caustic strictures and may increase complications in those etiologies. 1
Temporary Stent Placement:
- Offer fully covered self-expanding removable stents when previous methods have failed to maintain adequate esophageal patency, with complete dysphagia relief in approximately 40% of patients. 1
- Optimal stent duration is typically 4-8 weeks, though this varies by stricture etiology and length. 1
Incisional Therapy:
- Consider radial incisions using needle or IT knife at centers experienced in these techniques, particularly for short strictures (<1.5 cm). 1
Fluoroscopic Guidance:
- Use fluoroscopic guidance during dilation of refractory strictures to improve safety and precision. 1
Surgical Intervention
- Refer patients for antireflux surgery only when they are intolerant of acid suppressive therapy or have persistent troublesome symptoms (especially regurgitation) despite optimized PPI therapy. 1
- Surgery should be weighed against new post-operative symptoms including dysphagia, flatulence, inability to belch, and bowel symptoms. 1
- Do NOT recommend surgery for patients symptomatically well-controlled on medical therapy or as an antineoplastic measure in Barrett's esophagus. 1
- Esophagectomy is reserved for rare cases of long-segment stenosis (>2 cm) that fail all endoscopic approaches. 3, 4
Critical Pitfalls to Avoid
- Never discontinue or reduce PPI therapy prematurely—inadequate acid suppression is the most common cause of stricture recurrence. 1
- Avoid declaring a stricture "refractory" without first maximizing PPI therapy to twice-daily dosing. 1
- Do not use H2-receptor antagonists as primary therapy—they are ineffective for stricture prevention. 1
- Suspect perforation immediately if patients develop chest pain, breathlessness, fever, or tachycardia post-dilation; perform urgent CT with oral contrast. 1
- Refer complex strictures (>2 cm, angulated, irregular, severely narrowed) to centers with expertise in refractory stricture management. 1
Follow-Up and Monitoring
- Provide patients with contact information for the on-call team for post-procedure complications. 1
- Predictors for repeated dilation include non-peptic causes, fibrous strictures, and maximum dilator size <14 mm. 1
- Carefully selected patients with recurrent proximal strictures may be taught self-bougienage. 1, 5
