Dr. David Davtyan’s Story - The Weight Loss Surgery Center Of Los Angeles

Dr. David Davtyan’s Story

“I decided to become a doctor out of a very strong desire to help those in suffering, to reverse or cure diseases, and to bring joy and happiness to others. This is reflected both in the choice of my profession, as well as the subsequent choice of my specialties within medicine.”

Dr. David Davtyan’s Training

I received my medical education at the UCLA School of Medicine. Throughout my training, I have been blessed with outstanding teachers and extraordinary opportunities. During my second year at UCLA, I studied pharmacology with Doctor Louis Ignarro, an outstanding scientist, and teacher that went on to receive a Nobel Prize for his work related to the biological effects of Nitric Oxide.

Between the second and third year of medical school, I completed a post-sophomore fellowship in Anatomical and Surgical Pathology at the UCLA Department of Pathology. During those years, we were only beginning to discover the meaning of AIDS and diseases associated with it, and I was involved in one of the early publications of the results of
AZT treatment for AIDS.

After my cardiovascular surgery rotation, Doctor Hillel Laks, then the chief of cardiac surgery at UCLA, recommended me for Cardiovascular Surgery Externship and a Mitral valve repair course at “Le Club Mitrale” at Hospital Broussais in Paris, where I studied Mitral Valve repair techniques valve with Professor Alain Carpentier.

Surgical Oncology

After medical school, I decided to pursue a career in cancer surgery because cancer seemed to be the disease that was causing the most devastation, both physical and emotional, and it was also the most challenging opponent with infinitely varied and usually fatal presentations. I chose cancer surgery because it seemed to be the only method that had the chance to cure this plague. To master this science the best, I chose the M.D. Anderson Cancer Center in Houston, Texas for my training.

After five years in Houston, I spent another three years at UCLA and John Wayne Cancer Institute in Los Angeles, specializing exclusively in Surgical Oncology. Throughout these eight years, I have been blessed with the most amazing teachers who have given me their best: at M.D. Anderson, doctors Charles Balch M.D, Rafael Pollock M.D, Douglas Evans M.D, Merrick Ross M.D; at Hermann Hospital, doctors Frank Moody M.D, Stanley Dudrick M.D, James “Red” Duke M.D, Thomas Miller M.D; at UCLA and John Wayne Cancer Institute, doctors Donald Morton M.D, Frederick Eilber M.D, Armando Giuliano M.D, Kenneth Ramming M.D, and many others.

Private Practice

I began implementing these techniques as I started working in private practice in 1997, based out of Cedars Sinai Medical Center, Century City Medical Center, and Hollywood Presbyterian Medical Center. At the latter two hospitals in Century City and in Hollywood, I established and directed multidisciplinary breast cancer treatment centers. Our Breast Centers were providing state of the art care utilizing techniques such as Intraoperative Lymphatic Mapping and Sentinel Lymph Node Dissection, while also being involved in the care of indigent, uninsured, and underinsured women by providing free breast cancer screenings, early detection, and treatment under BCEDP (Breast Cancer Early Detection Program) and BCTF (Breast Cancer Treatment Fund) programs.

At Century City, I was also involved with treatment of the primary and metastatic tumors of the liver using resection, as well as new, evolving therapies such as Cryoablation and Radiofrequency Ablation. I was also using these techniques while I was teaching surgical oncology at City of Hope Cancer Center and at UCLA Center for Health Sciences.

Weight Loss Surgery

In 2001, during a minimally invasive surgery conference in Snowbird, Utah, organized by Dr. Phillip Shauer from Pittsburgh University, I saw the Lap-Band Procedure for the first time as it was being presented by Dr. Guy-Bernard Cadiere. This procedure fascinated me by virtue of its simplicity, safety, efficacy, adjustability, and reversibility. I spoke with Dr. Cadiere, one of the Lap-Band pioneers, and several months later, I was in Brussels to first undergo the procedure myself, and then to perform the procedure on several patients together with my surgeon.

Soon thereafter, this procedure was FDA approved in the United States and I was the first to introduce the Lap-Band procedure at Century City Hospital, then at Mission Community Hospital, where I became the Medical Director of the Lap-Band program. Soon after that, I became the first surgeon in California to perform the Lap-Band procedure at an outpatient surgery center.

As I’ve been fortunate to receive the best possible education in the field of Oncology, I have always been striving to replicate the same level of excellence in the field of obesity treatment.

I have also maintained the view that, as it is the case in Oncology, for better outcomes, the treatment of obesity needs to be comprehensive and multi-disciplinary. In addition to surgical weight loss and bariatric procedures, our treatments include medical weight loss, diets, medications, behavioral therapies, exercise, as well as the newer, technologically advanced approaches such as gastric balloons and other endoscopic therapies.

I have performed thousands of successful LapBand procedures. I also specialize in Sleeve Gastrectomy, Gastric Plication, revisional surgery (Lap-Band revisions, replacements, Band over Bypass, Band over Sleeve), Orbera and Obalon Endoscopic Gastric Balloons for weight loss, SILS (Single Incision Laparoscopic Surgery), Esophyx, Stomaphyx, and other endoluminal and NOTES (natural orifice transluminal endoscopic surgery) procedures (copies of certificates of training, as listed on lapbandla.com).

As a member of the scientific advisory board of the company Ellipse technologies, I was involved in the development of a patent for remotely adjustable advanced Gastric Banding systems.

Public Education through Media

I hold a firm belief that to overcome diseases like cancer or obesity, which are both major causes of morbidity and mortality, it is going to take not only major advances in science and technology and commitment on the part of individual patients and physicians, but also a huge investment in public education. In order to contribute to this larger goal, I have been involved in numerous public appearances, lectures, interviews on PBS, KDOC, Univision, Azteca-TV, and other media outlets (Links to these interviews, one per network).

Using my knowledge of many foreign languages, I’ve also been involved in the education of local ethnic communities (Hispanic, Russian, Armenian, Romanian, and others) [include pictures of Lectures.

In addition, I have been involved with on-line obesity communities such as lapbandtalk.com, obesityhelp.com, and Obesity Help Magazine (member of E very dedicated, first class team of assistants and physician extenders ditorial Advisory Board), to provide patient guidance and education beyond my private practice.

Charitable Work

During this period, I was on the Board of Directors of several charitable organizations. As the President of the Armenian American Medical Society of California and as a board member for the Valley Chapter of the American Cancer Society, I organized several joint projects on breast cancer and other cancer awareness among Armenian women in Los Angeles. In recognition of my work, I received numerous commendations from the City Mayor’s Office, California Governor, California Assembly, and U.S. Congress.

I benefited from tremendous support from my family. My father, an opera singer, and my mother, a history teacher, were always very supportive of my every undertaking. My wife, who I met in medical school, has been my strongest supporter since, and has been the greatest inspiration for most of my achievements. I am extremely grateful to my wonderful wife and children, who bring joy to my life and inspire me to excel both as a surgeon and as a family man.
