Gastric sleeve stricture is a narrowing of the sleeve that can occur after sleeve gastrectomy, causing dysphagia, vomiting, reflux, food intolerance, or inability to advance diet. Strictures may develop at the incisura angularis (mid‑sleeve) or near the gastroesophageal junction. Management includes endoscopic balloon dilation, endoscopic stenting, or surgical revision depending on severity, location, and response to treatment.

For mild or moderate strictures, endoscopic balloon dilation is performed under sedation. A balloon is passed through the stricture and inflated to widen the narrowing. For refractory or severe strictures, surgical options include seromyotomy, revisional sleeve gastrectomy, conversion to gastric bypass or OAGB, or seromyotomy with partial resection. The approach is tailored to stricture severity, location, and prior treatment response.

Benefits include resolution of dysphagia, improved food tolerance, reduced vomiting, improved reflux control, and restoration of normal food passage through the sleeve. Patients typically experience rapid symptom improvement after successful dilation or surgical revision.

Candidates include patients with dysphagia, vomiting, food intolerance, reflux, inability to advance diet, or obstructive symptoms after sleeve gastrectomy. Endoscopy or imaging typically confirms the stricture location and severity.

Endoscopic dilation is performed under sedation. A balloon catheter is advanced through the stricture and inflated under fluoroscopic or endoscopic guidance. Multiple dilations may be required. Surgical revision is performed laparoscopically and may include seromyotomy, re‑sleeve, or conversion to a bypass procedure.

Risks include perforation, bleeding, recurrent stricture, reflux, and, for surgical revision, leak and nutritional deficiencies. Revisional surgery carries slightly higher risk due to scar tissue.

After endoscopic dilation: same‑day discharge, liquid diet for 24–48 hours, gradual advancement. After surgical revision: Days 1–3 liquids, Week 1–2 soft foods, gradual return to normal routines by 30 days.

Most patients experience complete or near‑complete resolution of obstructive symptoms. Recurrent strictures may require repeat dilation or surgical conversion. Long‑term success depends on the approach used.

Dr. Nestor de la Cruz‑Muñoz is a nationally recognized bariatric and metabolic surgeon with extensive experience diagnosing and treating sleeve strictures through both endoscopic and surgical approaches.

Weight loss is not the primary goal. Most patients maintain or modestly improve weight after stricture management. Conversion to bypass may provide additional metabolic benefit.

Stricture management improves food tolerance and nutritional status but has minimal direct metabolic impact unless combined with a metabolic conversion.

Long‑term success requires protein‑forward nutrition, resistance training, hydration, and consistent metabolic follow‑up after stricture management.

Sleeve strictures can worsen reflux. Conversion to gastric bypass is preferred for patients with both stricture and severe GERD.

If endoscopic dilation fails, surgical options include re‑sleeve, seromyotomy, or conversion to gastric bypass or OAGB for definitive symptom relief and improved long‑term outcomes.

Patients with strictures often have reduced protein intake. Restoring food tolerance allows resumption of adequate protein and resistance training to protect lean mass.

Most insurers cover stricture management when symptoms are documented with endoscopy or imaging. Surgical revision coverage varies by plan and medical necessity documentation.

Pre‑op requirements may include bloodwork, imaging, endoscopy, nutrition consultation, and medication adjustments.

Diet progresses from liquids to soft foods based on symptom resolution. Protein goals and hydration are prioritized to address deficiencies caused by prolonged intolerance.

Light activity resumes immediately. Resistance training resumes once nutritional status stabilizes and diet advances.
