Laparoscopic Sleeve Gastrectomy

Sleeve Gastrectomy is now becoming the most popular bariatric procedure in the United States and is the fastest-growing operation in the field of General Surgery. Currently, it is the most frequently chosen bariatric operation among Dr. Ahmad’s patients.

Dr. Ahmad has performed over 1550 Sleeve Gastrectomy procedures with zero mortalities and one of the lowest complication rates in the world.

Sleeve gastrectomy is a restrictive form of bariatric surgery that shrinks the stomach to approximately 15% of its original size. It is commonly performed on severely obese patients who are not healthy enough to undergo a successful gastric bypass, biliopancreatic diversion or similar major surgery. The procedure enables rapid weight loss with fewer complications than the more conventional weight loss surgeries, but its effectiveness loses stride because there is no intestinal bypass.

The actual sleeve gastrectomy procedure is quite simple and begins with the surgeon’s tools entering through a small incision made in the abdomen. The stomach is then stapled down and “re-sized” over a long tube, greatly reducing its volume. Once this newly re-sized stomach or “sleeve” is examined for quality and to ensure no leakage or bleeding,duci the excess stomach tissue is then excised. The direct removal of stomach tissue also has a secondary metabolic effect by reng the secretion of the hormone Ghrelin, which is responsible for inducing hunger. The lining of the stomach is one of the few areas of the body to actually produce and secrete Ghrelin, most of which is removed during the procedure.

Risks and Complications of Sleeve Gastrectomy

As with any surgery, there are inherent risks to undergoing sleeve gastrectomy. Specific to bariatric surgeries, including the sleeve gastrectomy, is the risk of leakage and bleeding. Although the newly formed stomach sleeve generally fares well while it heals within the body, leakage and bleeding may occur from suturing or re-approximation of the new stomach before concluding the surgery. Due to drastic change in the size of the stomach, a patient may over ingest food so severely that is can cause a disruption to the newly formed stomach and may exacerbate these conditions. Additionally, the narrow size of the stomach may be vulnerable to large chunks of poorly masticated (chewed) food getting stuck, causing discomfort and pain to the patient.

Advantages and Disadvantages of Sleeve Gastrectomy

The following is a list to summarize the pros and cons to sleeve gastrectomy in comparison to other bariatric techniques:

Advantages of Sleeve Gastrectomy:


  • No malabsorptive complications or related deficiencies
  • No risk of ulcer
  • Gastric dumping syndrome is largely avoided
  • Normally laproscopic, reducing recovery time
  • Removes gland that secretes Ghrelin, hunger hormone
  • No foreign bodies (bands, tubes etc) permanently inside body
  • No “tightening” needed for further weight loss


Disadvantages of Sleeve Gastrectomy:


  • Overall less effective than Gastric Bypass in weight reduction and maintenance.
  • Irreversible
