Severe long esophageal stricture following hyperemesis gravidarum
2006
We report a 32-year-old female patient with esophageal stricture thought to have been caused by hyperemesis gravidarum. Eleven months before admission she had been admitted to another hospital, because of hyperemesis gravidarum, at 26 weeks of gestation. Marked and recurrent vomiting occurred and her consciousness gradually worsened. Three weeks later, her baby was delivered by Cesarean section. Postpartum progress was uneventful except that she developed dysphagia 5 months after delivery. Esophagography and upper endoscopy demonstrated severe esophageal stricture. Endoscopic balloon dilatation was performed four times, but was unsuccessful. Blunt dissection of the esophagus was then performed. Histological examination demonstrated marked fibrosis in the submucosal layer and muscular hypertrophy. Esophageal glands were not identified. In this case, esophageal stricture might have been associated with severe esophagitis due to recurrent vomiting and reflux of gastric contents during hyperemesis gravidarum.
