Studies in sclerotherapy: II. Two types of esophageal strictures following endoscopic sclerotherapy.

Esophageal stricture is an uncommon complication after fiberoptic endoscopic sclerotherapy, occurring in 10 (3.7%) of 265 patients. Eight patients improved and became asymptomatic after 4 weeks of treatment with antacids and antireflux measures, while another two patients required one dilatation each. We thus divided esophageal strictures after sclerotherapy into two types: one that responds to antireflux measures, and one that requires esophageal dilatation.
