Single-Incision Laparoscopic
Surgery Technique

Single-Incision Laparoscopic Surgery Technique This minimally invasive surgical technique requires only one incision inside the belly button, instead of multiple incisions on the abdomen. SILS is truly "scarless" surgery and a good choice for anyone concerned with scarring. Dr. Thoman is a leader in minimally invasive surgery and was the first surgeon on the Central Coast to perform this technique.

Featured Patient Story

Lynda, a kindergarten teacher and mother, suffered from exhaustion, depression, and embarrassment from her obesity. At 305 pounds and barely 5 feet tall, she chose gastric bypass surgery with Dr. Thoman to enhance her life.
