Abstract
Short cicatricial stenoses following surgery of the upper gastrointestinal tract are difficult to treat and have a high recurrence rate. A method of eliminating stenoses endoscopically with the aid of diathermy is described. This method has, to date, been employed in 51 patients, and only a single serious complication was observed. The procedure can be recommended, since reoperation with resection of the anastomosis is associated with a very high rate of complications. A new method of treating scar stenosis in the upper GI tract, which develops in particular after surgical anastomosis of the esophagus, is described; in 51 patients this method helped replace bougienage. This method obviates the need for life-long, unpleasant dilatation with the bougie in the mostly elderly patients.
