The Finney strictureplasty is performed by folding the diseased bowel on itself and creating a large opening between the two loops.
A longitudinal enterotomy is then performed halfway between the mesenteric and the antimesenteric side on the folded loop.
The opposed edges of the bowel are sutured together to create a short side-to-side anisoperistaltic enteroenterostomy.
Concerns about long-term complications, such as bacterial overgrowth in the bypassed segment, limit the length of the stricture to be addressed by this strictureplasty to less than 15 cm.
[3] Strictureplasties are categorized into three groups: Conventional, intermediate, and complex procedures.
