[Benign cicatricial stenosis of colorectal anastomosis: considerations on 2 cases].

During the surgical treatment of two patients with benign anastomotic colorectal stenosis, the Authors registered the presence of concomitant tenacious adherence of the anastomotic line to the sacral bone. Such event, according to the Authors, could represent one of the causes of failure and greater risk of perforation during the treatment with the different endoscopic therapies that, nevertheless, ought to be considered the gold standard in the therapy of benign structures. The Authors developed their hypothesis physiopathologic on the basis of personal experience and of the search a diagnostic procedure able to highlight the presence of a tenacious adherence with solid structures during the operative evaluation. If further studies focused on this subject will bring to satisfactory results, this would represent a further aid for the evaluation of the best therapeutic approach of the benign post anastomotic stenosis.
