overview

I have been involved in minimally invasive gynecological research and published over 40 clinical articles, case reports, and medical commentaries covering both obstetrical and gynecological topics. My clinical practice is as an OB/GYN hospitalist at CHI Saint Joseph Regional Hospital in Bryan, Texas.

I am a published author on in office gynecologic surgery and was part of the FDA post-approval study for the Essure 305 system, as well as the investigational Essure 505 device. Other areas of research publications include therapies for abnormal uterine bleeding, post-partum sentinel events (retained surgical items), and female sexual health.

Dr. Chapa has served as a peer reviewer for the American Journal of Obstetrics and Gynecology and the Journal of Surgical Case Reports. Additionally, he has served as a medical research consultant to Johnson & Johnson/Ethicon, Bayer Healthcare, Smith&Nephew, Inc., and Cooper Surgical. From 2007-2012, Dr Chapa authored aspects of the professional education content for obstetricians and gynecologists for these medical corporations.

Dr Chapa has taught as an invited physician-faculty member in South Africa, Israel, the European Union, The Netherlands, Norway, Ireland, Chile, Columbia, and Canada due to his unique lecture style and passion for evidence based learning.
