About the ReShape Gastric Balloon Non-Surgical Procedure - Medical Monday Segment with Great Day Houston  

This segment is an interview with Doctor Robert Marvin by Debra Duncan regarding the Reshape Balloon. This procedure is endoscopic, meaning noninvasive with minimal recovery time and reduced pain. The double balloon system is important for maximum weight loss results and for the patients safety. The balloons are removed after 6 months. This allows the patient to feel full while consuming less food overall, thus reducing caloric intake. In addition the Reshape website provides 1 year of support to teach the patient new eating habits and includes fitness advise. For the obese to morbidly obese patient, this offers a potential reduction of excess body weight within a short amount of time. The overall benefit to the patients health in reducing future metabolic issues is a longer and more active life.

About Dr. Marvin
Dr. Marvin


Doctor Robert Marvin is a Board Certified Surgeon who specializes in Minimally-Invasive Surgery (Laparoscopic Surgery) for the cure of Morbid Obesity. He has additional Certification in Surgical Critical Care and has been recognized by the American Society for Metabolic and Bariatric Surgery (ASMBS) as a surgeon practicing at a Center of Excellence in Obesity Surgery.

Dr. Marvin is affiliated with Nobilis Health. He utilizes Southwest Freeway Surgery Center when a surgical procedure is required. Southwest Freeway Surgery Center is an outpatient ambulatory surgery center, offering patients a quality of care comparable to a concierge and a convenient alternative to a hospital-based care.  

Dr Marvin grew up in Orange County and attended the University of Southern California where he studied in the Honors program known as the Thematic Option. He was elected to Phi Beta Kappa and graduated Magna Cum Laude with a Bachelor’s degree in Biology in 1985. He then spent the next four years in Montreal, Quebec, Canada at McGill University at medical school, and subsequently graduated with the degree of MDCM in 1989.

Dr Marvin began his Residency Training in San Antonio at the University of Texas Health Science Center in 1989. He was chosen as the Administrative Chief Resident for the General Surgery in his final year, and was designated the Outstanding Laparo-endoscopic Resident Surgeon in 1994.

In 1995 he moved to Houston, Texas where he did additional training as a Fellow in Surgical Critical Care at the University of Texas Houston. The following year he was asked to join the Faculty as an Assistant Professor of Surgery and taught at Hermann Hospital with the Trauma Service. He practiced general surgery, critical care and trauma surgery until 2000. During that time he conducted clinical research and his work was published in multiple medical journals such as the American Journal of Surgery and the Journal of Trauma. He also was the main author on the chapter on Critical Care in Sabiston’s Textbook of Surgery that year.

In September 2000 he left his professorship to enter a Private Surgical Practice. Dr. Marvin has done additional training to learn the techniques of Laparoscopic Gastric Bypass (1992), the Laparoscopic Adjustable Gastric Band (2004), Laparoscopic Gastric Sleeve (2007) operations, and now in 2017, Endoscopic Sleeve Gastroplasty. Since the inception of his Obesity Surgery practice in 2002 he has performed surgery for more than 1000 patients suffering from Morbid Obesity with excellent outcomes and low complication rates. Because of the quality of this care he was recognized as a Surgeon practicing at a Center of Excellence standard by the ASMBS in 2006.
