[The endoscopic treatment of postoperative stenoses of the upper digestive tract].

The authors compare their experience in dilatation of postoperative benign esophageal strictures. A total of 60 patients (37 males, 23 females: mean age 52), all with severe dysphagia, from January 1985 to September 1995, underwent endoscopic dilatation: 32 of these with Savary dilators and 28 with balloon dilators. Dilatation was effective in 93% in both groups.

[Indications and limitations of endoscopic sclerosis in esophageal varices: our current approach].

From January 1987 to December 1993, 171 patients affected by portal hypertension with bleeding complications underwent endoscopic variceal sclerotherapy. Results show that this technique is particularly effective for the hemostasis, therefore in high generic or specific risk patients is becoming a good alternative to traditional surgery.

[The complications of diagnostic colonoscopy].

Major complications of diagnostic colonoscopy based on a series of 17.583 procedures performed from 1980 throughout 1991 are reported. No higher risk of colon perforation was registered either performing total or partial colonoscopy, for the site of perforation was in most cases the sigmoid colon.
