Hayat Mousa, MD, is Director of the Suzi and Scott Lustgarten GI Motility Center, Director of the Frontier Program for Precision Diagnosis and Therapy for Pediatric Motility Disorders, and Program Director of the Advanced GI Motility Fellowship – all at Children’s Hospital of Philadelphia (CHOP). She is also the Suzi and Scott Lustgarten Endowed Chair for Clinical Care of GI Motility Disorders and a pediatric gastroenterologist with the Division of Gastroenterology, Hepatology and Nutrition at CHOP, and Endowed Chair and Professor at the Perelman School of Medicine at the University of Pennsylvania.

Dr. Mousa joined CHOP on Sept. 1, 2020, from her previous role as Clinical Director of Pediatric Gastroenterology and Director of the Neurogastroenterology and Motility Center at Rady Children's Hospital-San Diego, CA.

Dr. Mousa is a national leader and world-renowned expert in pediatric gastrointestinal (GI) motility disorders. She was trained at Children's Hospital of Pittsburgh, with broad exposure to all GI disorders including liver disease, small bowel transplantation and GI motility disorders. Subsequently, she joined the GI group at Nationwide Children's Hospital in Columbus, OH, where she developed its Motility Center, served as Medical Director for Motility for 15 years, and served as Fellowship Director of a GME-approved training program in pediatric motility disorders for 10 years.

Dr. Mousa’s key interests include gastroparesis, gastric electric stimulation (GES), chronic intestinal pseudo-obstruction, swallowing disorders, constipation, cecostomy, sacral nerve stimulation, rumination, gastroesophageal reflux, Hirschsprung's disease, GI motility diseases and other functional disorders. She has special clinical expertise in managing patients in multidisciplinary settings and had an active role in developing both aerodigestive and colorectal multidisciplinary teams.

Since Dr. Mousa’s pediatric GI fellowship training at Children’s Hospital of Pittsburgh, her clinical and research activities have been focused on motility and functional GI disorders. In her prospective clinical trials, she evaluated GI physiology, as well as investigated the pathophysiology of functional GI disorders, specifically the changes in gastric accommodation and compliance after fundoplication, and clinical outcomes after gastric electric stimulation and sacral nerve stimulation. She pioneered the use of gastric electric stimulation in pediatrics at Nationwide Children’s Hospital in collaboration with the pediatric surgeon and motility team. She and the team recently reported their 10-year experience in pediatric gastric electric stimulation. Most recently, Dr. Mousa has begun applying body surface gastric mapping (BSGM) to pediatric clinical research at CHOP.

Dr. Mousa’s contributions to science include innovation in the following areas:

  • High-resolution electrogastrography: In collaboration with biomedical engineering, Dr. Mousa has helped validate non-invasive, high-resolution electrogastrography (EGG) by simultaneously performing antroduodenal manometry studies and HR-EGG using a wearable multi-channel system and artifact removal signal processing methods. Dr. Mousa’s team also evaluated the benefits of using cutaneous, high-resolution electrogastrography (HR-EGG) in subjects with active foregut symptoms and found that abnormal spatial parameters – detected by cutaneous HR-EGG – correlated with a severity of upper GI symptoms, regardless of gastric emptying. This non-invasive diagnostic study has the potential to lead therapeutic intervention in patients with foregut functional symptoms. Dr. Mousa hopes to soon offer this technique to patients at CHOP with functional GI disorders and implement interventions based on their personal gastric rhythm.
  • EndoFLIP technique: Understanding the pathophysiology of dysphagia and offering a cure were the drivers to master EndoFLIP technique in patients with dysphagia. Dr. Mousa collaborated with biomedical engineering and created a program for an automated analysis of the dynamic changes and dispensability findings. In this prospective study, the team aimed to investigate whether esophageal compliance is a more sensitive measure than esophageal dispensability in detecting epithelial remodeling on regional and global esophageal levels in children with eosinophilic esophagitis (EoE) compared to controls. Dr. Mousa and her research team hypothesized that compliance was a stronger indicator of remodeling than distensibility. She helped standardize the protocol for the FLIP catheter position and collaborated with biomedical engineering to develop an automated analysis protocol.
  • Neuromodulation of the gastrointestinal tract: Dr. Mousa has also examined gastric pacing in the management of patients with gastroparesis and evaluated the benefits of gastric electric stimulation on children with gastroparesis and functional dyspepsia. In addition, she and the team have evaluated the use of sacral nerve stimulation in patient with defecation disorders, and the value of colonic motility in predicting the outcome of cecostomy placement in patients with severe constipation.
  • Non-invasive assessments of gastrointestinal transit time. Dr. Mousa has also investigated the sensitivity and validity of the Wireless Motility Capsule Test in diagnostic capsule endoscopy in children.

Dr. Mousa is very passionate about organizational leadership and process improvement. She has held several leadership positions and received certificates in leadership from CHOP and Rady Children’s Hospital. Dr. Mousa has published extensively on topic including chronic intestinal pseudo-obstruction; pre- and post-transplantation; gastric accomodation and compliance after fundoplication; gastroesophageal reflux and its association with apnea and respiratory symptoms; and how gastric pacing impacts gastric function and quality of life.

She is an active member of several professional societies including the American Neurogastrointestinal Motility Society (ANMS), North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN), and the American Gastroenterology Association (AGA). She currently chairs NASPGHAN’s Aerodigestive Special Interest Group (SIG). She organized the 2021 NASPGHAN Single Topic Symposium and led the publication of its proceedings with the Aerodigestive team.

Dr. Mousa has been awarded the NASPGHAN Motility Prize, Nationwide Children’s Hospital’s IMPACT Business Process Improvement Program Award, and the Award of Excellence at Rady Children’s Hospital, San Diego, CA.

“I am grateful for the opportunity to partner with my colleagues and parents on the care of those special patients,” Dr. Mousa says. “I am a physician dedicated to my patients, my team and my institution. I am committed to the field and honored to be at CHOP.”
