Introduction: Gastric volvulus is a rare event that occurs when the stomach rotates onto itself along its transverse or longitudinal axis. Patients present with mild or intermittent gastric obstructive symptoms. Although the majority of cases are referred for emergent surgical repair, we present a case successfully treated with endoscopic reduction and subsequent surgical gastropexy.

Case Description/Methods: A 52-year-old man with a history of morbid obesity and a large hiatal hernia, presented with one day of refractory epigastric pain and heartburn. CT of the abdomen showed a large paraesophageal hernia (PEH), intra-thoracic herniation of the distal stomach and gastroduodenal junction, and mesenteroaxial rotation consistent with acute gastric volvulus. EGD showed torsion of the gastric body and antrum, intra-thoracic herniation, and no evidence of mucosal ischemia. Following extensive suctioning of gastric debris, the herniated parts of the distal stomach were detorsed and an NG tube was placed. Follow-up showed a successful reduction in bowel loops. The patient subsequently underwent laparoscopic gastropexy and recovered uneventfully. He was discharged with an eventual plan for Roux-en-Y gastric bypass.

Discussion: Although gastric volvulus is rare, presentations can range from mild obstructive symptoms to severe ischemia, sepsis, or gastric perforation. Up to 30% of gastric volvulus cases are described as primary, from laxity and disruption of the stomach’s ligaments (gastrohepatic, gastrocolic, gastrolienal, and gastrophrenic). The other 70% of cases result from an anatomic issue involving the stomach, spleen, or diaphragm, including paraesophageal hernias. More specifically, gastric volvulus due to PEH is a result of the migration of the gastroesophageal (GE) junction from the abdomen into the chest. Acute gastric volvulus secondary to PEH is frequently addressed with emergent surgery. However, alternative approaches, including initial endoscopy followed by gastropexy, as well as watchful waiting followed by elective surgery have shown to be similarly efficacious. Patients who present with acute gastric volvulus without evidence of critical illness (ie gastric necrosis, ischemia, or sepsis) can be managed successfully with initial endoscopy. These patients are candidates to also receive a gastropexy prior to eventual elective surgery. Our case adds to the present data with validation of endoscopic reduction followed by surgical gastropexy as a viable method to approach PEH and acute gastric volvulus.
