About sleeve gastrectomy

Dr. Thoman was the first surgeon on the central coast to perform the laparoscopic sleeve gastrectomy, and still the only surgeon able to perform it through a single incision at the belly button. This procedure involves removing around 90% of the stomach leaving a tube or “sleeve” of stomach. It has become more popular in the last 5 years.

Understanding laparoscopic sleeve gastrectomy

The Sleeve Gastrectomy works like all metabolic weight loss procedures, by lowering your body’s set point for weight by altering the gastrointestinal hormones.


The Sleeve Gastrectomy, like all surgeries Dr. Thoman performs, is done with tiny incisions and results in most people fully recovered within a week or two.

The sleeve creates weight loss and cures health problems almost as well as the gastric bypass without any of the long term risks.  Around 10% of gastric bypass patients will eventually need another surgery because of ulcers or internal hernias, the sleeve eliminates that risk.  Your intestines are not touched and that dramatically decreases your chance of problems down the road.


Laproscopic sleeve gastrectomy is so effective that weight loss begins immediately after the surgery and usually continues for approximately 12 to 18 months. Your rate of weight loss will depend on your height and weight prior to surgery, as well as your diet, level of exercise, and daily calorie intake. You can expect to lose about 70-80% of your excess body weight within 18 months of surgery.

Our patients are consistently thrilled with the significant weight loss they are able to achieve. Surgery can improve the health, self-esteem, and quality of life of many of the women and men who have chosen our practice

Risks and complications

During your consultation, Dr. Thoman will thoroughly review your health history and discuss the risks and complications associated with Sleeve Gastrectomy surgery, including:

  • Pulmonary embolism: A potentially fatal blood clot in the lung

  • Gastric leak: Leakage of stomach contents resulting from improper healing

  • Stomal stenosis: Narrowing of stomach requiring an endoscopy or surgery

  • Heartburn: While the gastric bypass and Lap Band can cure heartburn, the sleeve can create it or make it worse. Most patients will respond to an acid reducing pill.  Some actually have less heartburn if it was from a hiatal hernia that Dr. Thoman will fix.
