The endoscopic treatment of benign esophageal strictures by balloon dilatation

Benign strictures of the esophagus are serious illnesses that have a great adverse effect on the quality of life of patients, There are several methods of treatment. In this study the endoscopical balloon dilatation technique was used. All dilatations were performed under analgosedation, and plastic balloons (6-25 mm) were used. Ninety dilatations were performed between 1995 and 1997, Twenty-two patients were diagnosed as having benign stenosis of the esophagus, We evaluated the effectiveness and the complication rate of the method. All patients except two showed immediate improvement: 59% were cured; 18% had at least one recurrence of the stenosis; 9% had improvement but treatment continues; 14% required other treatment. We encountered two cases with major complications, i.e. perforation, Balloon dilatation seems to be an effective and safe method for treatment of the benign esophageal strictures and is well tolerated by patients. Endoscopic control is sufficient, and radiographic control is not required. Randomized prospective studies are needed to establish the role of this method in comparison with other treatments.
