Massive esophageal bleeding in long-standing achalasia complicated by esophageal carcinoma and aspirin-induced stasis ulcer: Case report.

RATIONALE: Esophageal hemorrhage may occasionally develop subsequent to esophagitis and stasis ulcer, but potentially fatal esophageal bleeding is very uncommon in primary achalasia.

PATIENT CONCERNS: We describe a case of a 64-year-old man with long-standing achalasia and megaesophagus who presented acute episodes of life-threatening upper gastrointestinal bleeding.

DIAGNOSES AND INTERVENTIONS: Five esophagogastroduodenoscopies (EGD) were conducted and during each large amount of static food, bloody material, and clots should be removed from the esophagus because of impaired esophageal transit. Eventually, diffuse multiple irregular ulcers were observed in the middle and lower portions of the esophagus that were presumed to have been caused by aspirin stasis based on considerations of previous drug use. EGD also revealed a 2.0 × 2.5 cm flat nodular lesion with central ulceration at the mid-to-lower esophagus and adherent blood clots suggestive of bleeding stigma. The biopsy specimen demonstrated esophageal cancer. Accordingly, a diagnosis of massive esophageal hemorrhage in long-standing achalasia complicated by squamous cell carcinoma, possibly triggered by acute mucosal irritation and ulcer caused by aspirin stasis, was made. The patient then successfully underwent the Ivor-Lewis operation. Resultantly, the tumor was diagnosed as moderately differentiated squamous cell carcinoma stage IIA (T2N0M0).

OUTCOMES: The patient's postoperative course was uneventful, and no evidence of tumor recurrence or metastasis has been found during the 6 months of follow-up examination. He was tolerating normal food with only minimal reflux symptoms.

LESSONS: Although, fortunately in the described case, esophageal cancer was diagnosed at a relatively early stage because it is the acute presentation of life-threatening upper gastrointestinal bleeding, this report cautions that when symptoms of dysphagia are aggravated, taking drugs capable of acting as local irritants, such as aspirin, could cause fatal esophageal hemorrhage in achalasia.
