[Radiological findings after jejunoileal shunt for the treatment of extreme adiposity].

Bypassing the small intestine is used for the treatment of extreme obesity. Because of the altered morphological and functional situation, the assessment of radiological sequelae is different. Passage is rapid, continuous observation is essential. Passage time is related to weight loss. Multiple small fluid levels in the small intestine are an expression of the stasis in the bypassed intestinal loops. They are of clinical importance only when there are other complaints at the same time. A reflux is of particular importance in relation to the expected loss in weight. Absorption studies with radioactive isotopes show the extent of the malabsorption.
