Abstract
We present a case of early gastric cancer in the pylorus with a type 3 hiatal hernia, which was treated by endoscopic submucosal dissection (ESD). A 70-year-old man was referred to our hospital with a hiatal hernia. Endoscopy revealed early gastric cancer, and we performed an ESD adaptation at the pylorus. The ESD was successful, but post-ESD pyloric stenosis occurred. Symptoms of hiatal hernia worsened because of the pyloric stenosis. Laparoscopic hiatal hernia repair with Toupet fundoplication and Heineke-Mikulicz pyloroplasty was simultaneously performed. The postoperative course was good, and follow-up after discharge was uneventful. To our knowledge, there have been no reports in which laparoscopic hiatal hernia repair, fundoplication, and pyloroplasty were simultaneously performed for a substantial hiatal hernia with post-ESD pyloric stenosis.
