[Stenosis caused by mechanical colorectal anastomosis. Technique of plasty]

Stenosis occurs in 1.2 to 4% of the cases after colorectal anastomosis, especially after stapling. Ischaemia may have been favoured in our two cases. Treatment requires endoscopic dilatation or section of a sclerous diaphragm and may entail reconstruction of the anastomosis. The Kraske plasty is a simple and rapid procedure (case n. degree 1) and can be performed via endoluminal access (case n. degree 2) using a linear suture.
