Although the use of mesh reinforcement during large hiatal hernia repair may reduce the rate of recurrence, various mesh-related complications have been reported. A 65-year-old woman presented with dysphagia. The patient was diagnosed with a large hiatal hernia and treated with laparoscopic fundoplication and Collis gastroplasty with mesh repair. Six months after surgery, the patient presented with dysphagia and vomiting. Esophagogastroduodenoscopy showed migration of mesh material into the esophagogastric junction. We performed a proximal gastrectomy with mesh removal. The patient was discharged without any postoperative complications. Herein, we encountered a rare case requiring surgical treatment to resolve mesh-induced esophagogastric perforation after hiatal hernia repair. Mesh-associated complications, such as erosion or migration, should be considered as they may be more common than previously reported. Additionally, these complications are currently underscored in clinical practice. Regarding mesh applications, symptoms of mesh-related complications, such as dysphagia, should be carefully monitored for early detection.
