title: Jejunileal bypass. Roentgenographic observations.
abstract: Jejunioleal bypass procedures may be performed with the bypassed small intestine draining, as usual, into the cecum, or with end-to end anastomosis of the jejunum and terminal ileum, with the bypassed segment draining into the transverse colon through another anastomosis. Modifications of these methods have also beed devised. After good response with weight loss initially, most patients fail to continue to lose weight into the third year postoperatively. Some of the features which cause failure are: prolonged transit time, intestinal dilatation with mucosal hypertrophy, and reflux into the bypassed segment, in the earlier type of operation.
