Small bowel enteroclysis in surgically treated obesity.
OBJECTIVE
To define the indications, technical limitations and diagnostic yeld of small bowel transbuccal enema in the follow-up of surgical jejunoileal shunting in patients with complicated severe essential obesity.


METHODS
Three patients were submitted to surgical diversion: two of them underwent an intestinal bypass after Payne-De Wind (isoperistaltic end-to-side jejunoileostomy) and the other after Scott (end-to-end jejunoileostomy). The latter refers to intestinal recanalization and antiperistaltic lower end-to-side gastroenteric restoration.


RESULTS
Radiologic studies are the only means to depict the surgical small bowel. Radiographic follow-up needs barium sulfate administration and therefore cannot be performed any sooner than 30 days postoperatively. In the last three years the classic transbuccal enema has been performed with a Rollandi tube (with a terminal opening and a balloon). Both the anastomosis and the blind loop are difficult to demonstrate.


CONCLUSIONS
Jejunoileal bypass can be used to treat severe obsity uncontrollable otherwise, to reduce food absorption. Different severe complications may result and small bowel studies may permit to show late local complications. Small bowel enema is also indispensable in bypass reversal. There are no alternatives to this radiologic examination which is however very difficult to perform, because of the changes made by previous operation(s), and to interpret because the anastomosis, the sutured loop and wall changes are often poorly demonstrated.
