Endoscopic features of paraesophageal hernia complicated with partial gastric obstruction: A case report

Hiatus hernia is rarely found to be associated with partial gastric obstruction. We here report a patient with this condition. The patients had sudden onset of coffee ground vomitus without any symptoms of gastrointestinal obstruction. Esophagogastroduodenoscopy was performed and only twisted mucosa converging into a point near the esophagogastric junction was noted retroversion of the endoscope. The endoscope passed the narrowing point and then advanced into the distal stomach and pylorus. No gastric volvulus was noted, because the pylorus was patent and the level of the obstruction was almost as high as the fundus. A diagnosis of paraesophageal hernia with partial gastric obstruction was made. This diagnosis was later confirmed by an upper gastrointestinal series. Elective surgery was performed afterward. The patient remained well one year after surgery.
