Finney strictureplasty is indicated for strictures up to 15 centimeters. The Finney strictureplasty is performed by folding the diseased bowel on itself and creating a large opening between the two loops. This strictureplasty can be used to address longer strictures (>7 cm and ≤15 cm) than those manageable with the Heineke-Mikulicz technique (usually performed for strictures up to 7 cm).^[1]

The Finney strictureplasty is named after the Finney pyloroplasty, first described in 1937.^[2] The strictured loop is folded over itself at its midpoint section, forming a U shape. 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. The Heineke-Mikulicz Strictureplasty is the most common among the conventional stricutreplasties, the Finney strictureplasty is the most common intermediate strictureplasty, and the most common complex strictureplasty is the Michelassi Strictureplasty.^{[citation needed]}
