Radiographs (X-ray pictures) are taken while barium sulfate, a radiocontrast agent, fills the colon via an enema through the rectum. The term barium enema usually refers to a lower gastrointestinal series, although enteroclysis (an upper gastrointestinal series) is often called a small bowel barium enema.
The main aim of this study is to distend the proximal bowel through infusion of large amount of barium suspension. Otherwise, the distension of distal small bowel is generally similar with small bowel follow-through. Therefore, there is a need to pass a tube through the nose into the jejunum (nasojejunal tube) to administer large amount of ...
A jejunostomy may be formed following bowel resection in cases where there is a need to bypass the distal small bowel and/or colon due to a bowel leak or perforation. Depending on the length of jejunum resected or bypassed the patient may have resultant short bowel syndrome and require parenteral nutrition. [2]
Over the past several years assessment of small bowel diseases was performed by Barium follow through, or upper and lower gastrointestinal series, that provided plan film of bowel loop lumen, thanks to the swallowing or instillation of radiopaque agents mixed with water or other neutral contrast media.
[5] [6] Short-bowel syndrome was the cause for 73% of American intestinal transplantations in 2008, followed by functional bowel problems for 15% and other causes representing 12% of cases. [7] Natural SBS is mercifully rare, estimated to be 3 per 100,000 births. [8]
Jejunoileal bypass (JIB) was a surgical weight-loss procedure performed for the relief of morbid obesity from the 1950s through the 1970s in which all but 30 cm (12 in) to 45 cm (18 in) of the small bowel were detached and set to the side.
