title: [Utility of botulinum toxin in stasis esophagitis secondary to achalasia. Report of a case].
abstract: Upper gastrointestinal bleeding is an infrequent complication of achalasia. Stasis esophagitis is a rare cause of esophageal bleeding in which conventional forms of treatment may be associated with a high risk of complications. Botulinum toxin has emerged as a therapeutic alternative with few secondary effects. We present a case report of achalasia complicated by upper gastrointestinal bleeding secondary to stasis esophagitis which was successfully treated with botulinum toxin. Interesting aspects related to stasis esophagitis and the potential role of botulinum toxin in achalasia are discussed.
