anastomotic stricture
A narrowing at the surgical connection site that can occur after gastric bypass, causing swallowing difficulties and food intolerance.
Full Definition
Anastomotic stricture is a complication occurring in 3-15% of patients following Roux-en-Y gastric bypass, characterized by narrowing at the gastrojejunostomy site. Symptoms include progressive dysphagia, food intolerance, nausea, and vomiting, typically appearing 6-12 weeks postoperatively. The stricture results from excessive scar tissue formation during healing and can significantly impact quality of life and nutritional status. Treatment involves endoscopic balloon dilation, which is successful in most cases, though some patients may require multiple dilations or surgical revision in refractory cases.
Usage
Usage note: Use 'anastomotic' rather than 'anastomosis' when describing the stricture as an adjective.
