[Anastomotic stenoses correlated with the use of mechanical staplers in the surgery of esophageal cancer].

From 1990 to 1995, 187 patients underwent esophagectomy and esophagogastrostomy with the anastomosis performed inside the chest using a circular stapler. Twenty-three patients (12.3%) developed an anastomotic stricture. The incidence of anastomotic stricture was inversely related to the diameter of the stapler. Also concomitant cardiovascular diseases, morpho-functional disorders of the tubulized stomach (possible related to duodeno-gastric reflux) and neoadjuvant chemotherapy were recognized as significant risks factors. Endoscopic dilations were safe and effective in the treatment of anastomotic strictures.
