stenosis
Pronunciation: steh-NOH-sis
Abnormal narrowing of a body passage, particularly concerning anastomotic connections in bariatric surgery.
Full Definition
Stenosis refers to the pathological narrowing of a tubular structure or opening within the body. In bariatric surgery, stenosis most commonly occurs at surgical anastomoses, particularly the gastrojejunal connection in gastric bypass procedures. This complication can result from excessive scarring, ischemia, or technical factors during surgery. Symptoms include progressive dysphagia, vomiting, and inability to tolerate solid foods. Diagnosis is confirmed through contrast studies or endoscopy, and treatment may involve endoscopic balloon dilation, stenting, or surgical revision. Prevention involves careful surgical technique and adequate blood supply to anastomotic sites.
Usage
Usage note: Can affect any surgical connection; distinguish from functional obstruction.
