Expert in Laparoscopic Surgery

Dr. Guarista is a recognized expert in laparoscopic surgery. In fact, he trains other doctors in Tijuana, Mexico, in the latest advancements in laparoscopic technology.

Laparoscopic surgery is an alternative to traditional open surgery. Instead of making large incisions and exposing the interior of the body, laparoscopic surgeons make small incisions and operate within the body with the help of surgical cameras. When utilized by trained experts like Dr. Guarista, laparoscopic techniques result in fewer complications, reduced scarring, and quicker recoveries.

Dr. Guarista uses laparoscopic methods for all of his bariatric surgeries, including gastric sleeve surgery and gastric bypass surgery. To learn more about receiving expert care from Dr. Guarista in Tijuana, Mexico, contact our practice today.
