Gastric Volvulus, An Important Yet Commonly Overlooked Etiology of Upper Gastrointestinal Bleeding: A Case Study.

Gastric volvulus is a distinct and uncommon pathology that usually presents with vomiting secondary to gastric outlet obstruction and gastrointestinal bleeding with an association with hiatal hernia. We present a case of a 71-year-old female who presented to the emergency department (ED) with a three-day history of coffee ground emesis. Of note, the patient was recently in the hospital under medical observation two weeks prior, with similar complaints of hematemesis. Chest X-ray revealed a left basilar opacity representing bowel gas suggestive of a hiatal hernia. Intravenous proton pump inhibitors were initiated but due to persistent recurrence of symptoms and progressive discomfort, a computed tomography (CT) of the chest and abdomen was ordered. This revealed a partial gastric volvulus with signs suggestive of vascular compromise of the herniated part of the stomach. She subsequently underwent emergent laparotomy, repair of the hiatal hernia, and partial gastrectomy and gastropexy. Post-surgical biopsy findings showed focal mucosal necrosis and ulceration, focal foveolar hyperplasia, edematous changes, and overall congestion in the submucosal tissue. She was discharged five days later with no complications or recurrence of symptoms.
