RESUMO
The balloon dilatation or Savary-Gilliard dilatation was performed in 59 patients with benign esophageal stricture in Chungnam National University Hospital from September 1990 to August 1995. We reviewed the effect and the safty of each therapeutic method and the results were as foillows: 1) The cause of stricture were corrosive stricture(28 cases, 49,4%), anastomotic stenosis after gastroesophageal surgery(26 cases, 44.1%), stricture after endoscopic variceal sclerotherapy(3 cases, 5.1%), esophageal web(1 case, 1.7%) or stricture complicated by reflux esophagitis(l case). 2) The overall cure rate of balloon dilatation was 50%(l2/24 cases) and that of Savary-Gilliard dilatation was 77.1%(27/35 cases). The Savary-Gilliard dilatation group had a better result than the balloon group. 3) The perforation after Savary-Gilliard dilatation occurred in 4 cases~(6.7%). One case was treated surgically and three cases wiere treated medically. But there was no fatal complication. 4) The overall cure rate of anastomotic stenosis was 84.6%(32/38 cases) and that of corrosive stricture was 46.4%(13/28 cases). 5) The cure rate of Savary-Gilliard dilatation in corrosive esophageal stricture was 64.7%(ll/17) and that of balloon dilatation was 18.1%(2/11). 6) According to site of stricture, the cure rate of dilatation was 84.2% (32/38) in thoracic esophagus, 42.8%(3/7) in cervical esophagus and 28,5%(4/14) in multiple or long segmented stricture.(continue...)
