Vertical banded gastroplasty-gastric bypass is a surgical technique combining the advantages of the vertical banded gastroplasty with those of gastric bypass. The procedure was performed on 148 morbidly obese individuals: 83% were female, and 17% were male. Ages ranged from 15 to 64 years, with a mean age of 35. Mean percentage weight was 215% of ideal. The vertical banded gastroplasty is constructed by creating a 10 cc vertical pouch along the lesser curvature with a 5.5 cm supporting band. The pouch is fashioned in a way that the lower portion is free and mobile. This free segment of stomach is anastomosed by triangulation to a Roux-en-Y loop of jejunum, which is brought up in a retrocolic, retrogastric fashion. With 100% follow-up in the 19 patients who have reached 1 year, average excess weight loss has been substantial. There was one early postoperative complication requiring surgery. Two patients required late revisional operations. Vertical banded gastroplasty-gastric bypass is a relatively simple procedure to perform and has a low rate of complications. Gastric bypass in combination with a small banded pouch along the lesser curvature should result in substantial and permanent weight loss.

Inheritance of resistance to the fruit fly Dacus cucurbitae Coq., was studied in intervarietal crosses of watermelon Citrullus lanatus (Thunb.) Mansf. Two sources of resistance J 18-1 and J 56-1 were used. The resistance of watermelon to the fruit fly was controlled by a single dominant gene. The symbol Fwr has been proposed to denote the resistant gene.
