Gastroenterologist Mouen Khashab specializes in therapeutic endoscopy, and he oversees this group of practitioners across the Johns Hopkins enterprise. Nationally and internationally known in the field of interventional endoscopy, Dr. Khashab has contributed immensely to the field’s advancement as a minimally invasive means to treat gastrointestinal and pancreaticobiliary disorders.

He then completed a two-year fellowship at The Johns Hopkins Hospital before joining the faculty in 2011. A busy researcher, Dr. Khashab has published more than 600 papers in peer-reviewed journals. In 2013, he described the procedure called gastric peroral endoscopic myotomy (known as G-POEM) and was able to disseminate and teach it all over the world. Other procedures that he expanded include peroral endoscopic myotomy (POEM), peroral endoscopic myotomy with fundoplication (POEM-F), Zenker’s peroral endoscopic myotomy (Z-POEM) and full thickness resection. In 2022, he received the Master Endoscopist Award from the American Society for Gastrointestinal Endoscopy (ASGE) for his numerous contributions to the field.
