Abstract


A small bowel enema, sometimes referred to as an examination procedure of enteroclysis, is a specialist diagnostic imaging technique used to assess the small intestine from the jejunum to the ileocecal junction. Enteroclysis, in contrast to traditional small bowel follow-through testing, entails direct intubation of the small bowel to create controlled, continuous distension, enabling high-resolution mucosal imaging. Tumors, small bowel blockages, unexplained gastrointestinal bleeding, and Crohn's disease are the main conditions for which this operation is recommended. The test may be combined with magnetic resonance imaging (MR enteroclysis), computed tomography (CT enteroclysis), or fluoroscopy (traditional X-ray).

 

Procedural Overview & Methodology

  1. Patient Preparation: Before the exam, the patient fasts all nite and takes laxatives to make sure the bowels are completely free of gas and feces. They also follow a low-residue or clear liquid diet for 24 hours.
  2. Intubation: A flexible enteroclysis tube (such as a Bilbao-Dotter catheter) is inserted through the patient's mouth or nose, into the stomach, and into the proximal jejunum (usually distal to the ligament of Treitz) under local anesthesia and fluoroscopic supervision.
  3. Contrast Administration: The small intestine is directly infused with a liquid contrast medium, usually a barium sulfate suspension, sometimes followed by methylcellulose or air for double-contrast detail.
  4. Imaging and Positioning: Multiple structural pictures are captured as the intestinal loops are uniformly distended by the contrast. The patient may be instructed to alter physical postures (e.g., supine, prone, or oblique) so the radiologist can isolate and observe all parts of the small bowel.
  5. Completion: The contrast volume may be suctioned, the tube is carefully withdrawn, and the patient is permitted to return to a regular diet with instructions to increase fluid intake in order to evacuate any residual barium after all required diagnostic pictures have been obtained.
