stricturotomy

Stricturotomy is a surgical procedure in which a stenotic segment is incised to widen the narrowed lumen. It can be performed endoscopically or by open, laparoscopic, or percutaneous approaches and is used to treat benign strictures in various organs, including the urethra, esophagus, biliary tract, and intestine. The objective is to relieve obstruction while preserving function.

In endoscopic stricturotomy, a scalpel, cold knife, or electrosurgical device makes precise incisions along the stricture to widen the lumen; laser methods may be used in some settings. Open or percutaneous stricturotomy exposes the stricture directly and incises it under vision, often with careful hemostasis.

Indications include symptomatic, non-neoplastic strictures that are short to moderate in length, when less invasive measures have failed or are unlikely to provide durable relief. Common sites include the urethra, esophagus, and biliary tract in selected patients.

Outcomes vary by site and stricture characteristics; recurrence after stricturotomy is possible and may require repeat procedures. Potential complications include bleeding, infection, perforation, or fistula formation.

Alternatives include balloon dilatation, stenting, or definitive reconstructive procedures such as urethroplasty or stricture repair, depending on location and tissue quality.
