Colin James Thomas, MD

I graduated from Boston University with a degree in biology/neuroscience and completed my medical degree and master's of science in translational research degrees at the University of Pennsylvania Perelman School of Medicine. My general surgery training was completed at Massachusetts General Hospital and Harvard Medical School. I subsequently completed a fellowship in foregut surgery and comprehensive flexible endoscopy at University Hospitals Cleveland Medical Center. I am currently assistant professor of surgery at HUP and affiliated faculty in the Penn School of Engineering and Applied Science's General Robotics, Automation, Sensing, and Perception (GRASP) Laboratory. I believe in working closely with patients to help them meet their goals for their gastrointestinal conditions. I offer surgical and endoscopic treatments for gastrointestinal diseases and have a specific interest in disorders of the foregut, including diaphragmatic/paraesophgeal hernias, gastroesophageal reflux (GERD), diaphragm dysfunction and paralysis, achalasia and other GI motility disorders. I offer complex minimally invasive approaches to diseases including robotic paraesophageal and hiatal hernia repair, per oral endoscopic myotomy (POEM) for achalasia, ZPOEM for Zenker's diverticulum, laparoscopic common bile duct exploration, and endoscopic GI tract defects such as strictures and leaks as well as diaphragm pacing and robotic abdominal wall hernia repair and reconstruction. I also offer bariatric endoscopy including endoscopic sleeve gastroplasty and transoral outlet reduction. My laboratory, the Penn Computer Assisted Surgery and Outcomes (PCASO) Laboratory, is focused on the use of technology to improve surgeon performance and decision-making, in particular on the translation of artificial intelligence and computer vision for surgical video analysis. I have authored over 60 publications in journals such as the New England Journal of Medicine, Nature Biotechnology, and Annals of Surgery, and am the editor of the textbook Artificial Intelligence in Surgery: Understanding the Role of AI in Surgical Practice.
