This thesis includes 60 morbidly obese patients .They were selected according to the followings: 1- Age: 18-45 years. 2- BMI: 40kgIm2 3- BMI: 35-40 Kg/m2 with co-morbidities that can be improved with operation. 4- The patients are morbidly obese for more than 5 years. 5- No alcoholism or psychosis 6- No endocrinal causes for obesity. Patients with odd numbers were grouped for LVBG while those with even numbers were grouped for LSAGB (Swedish type). Minimum postoperative follow up for 12 months. 86.6% of our cases were age 42 years and 46 of the cases were female and 14 were male. 24 cases (40%) had life-long type obesity while the remaining 36 cases had adult-type of obesity. 60% of the cases were both gorger and sweet eater, 10 cases were gorger only, while 14 patients denied both gorger and sweet eater. All our patients had serious preoperative trials to loss excess weight including dieting (loo%), Acupuncture (86.6%), drugs and herbs (80% each) and finally surgery. Many co-morbidities were detected in our patients including locomotors problems (83.3%), hypertension (20%).GERD , history of DVT (13.3 % each), incontinence of urine (10%) and finally Pickwikian syndrome and DM (6.6% each). 6 of our married female patients had primary infertility and 4 females were divorced because of this problem. There was family history of obesity in 56.6% of our cases. 34 cases. (56.6%) had both central and peripheral obesity, 24 cases had central obesity while only 2 patients had peripheral obesity. 20 patients were anemic, 12 cases had hypoxia while only 2 patients had Pickwikian s yndrome. U .S a bnorrnalities w ere d etected in 53.5% of the cases, while ECG abnormalities were present only in 6.6 % cases The mean preoperative BMI was 52.8kglm2 for LVBG group and 5 1.2 kg/& for LSAGB group. The mean operative time was 150 min (2-3hr) for LVBG group and 90 rnin (1 - 2h) for LSAGB group. The mean hospital stay was 4 days (2- 6days) for LVBG group and 3 days (1-5 days) for LSAGB. We had 2 cases died postoperatively within one month, one case for each group. In LVBG group, the post discharge complication included solid food intolerance (3cases) and re-increase in body weight after initial loss (one case). In LSAGB group, we had injection port abscess (one case) , solid food intolerance (2cases),band erosion (one case) and band slippage (one case) I Em% at one year was 51% in LVBG (mean BMI = 37.4 k g / d and 49% in LSAGB group (mean BMI = 37.7 kg/rn2.
