Since morbid obesity is known as a major cause of psychosocial problems beside its common adverse effects like cardiovascular and metabolic diseases, a lot of researches have been performed to find an effective treatment including surgery. Surgical methods were improved by invention of minimal invasive surgeries. Laparascopic Sleeve Gastrectomy (LSG) and Laparascopic Adjustable Gastric Banding (LAGB) are the methods which have become common in most of developed countries.

Due to cultural, economic and social differences between our country and developed countries, we have designed this research to compare the efficacy and complication of these two methods six months after operation in hospitals affiliated to Shiraz University of Medical Sciences.

Documents of patients operated with one of these two methods were reviewed, and necessary information was inserted in prepared forms. We called patients if further information was needed. Then this data was analyzed with Chi Square 2Sample Independent T- test and Paired T Test by SPSS 16 software.

Seventy patients were operated with LSG and 25 with LAGB. The Mean weight of LSG group was 120.73 and 120 for LAGB. The Mean weight loss in LSG was 29.99 and 19.60 in LAGB. There was no statistically significant difference regarding early complications between the two methods; although, long term complications such as gastric stenosis and band displacement were statistically more in LAGB.

It seems that both LSG and LAGB are efficient in weight loss but LSG can lead to more weight loss, better correction of blood pressure and less long term complications.
