Summary

Diagnosis and treatment of small bowel pathologies remain challenging due to the long length of the small bowel. Obscure gastrointestinal (GI) bleeding with negative upper and lower GI workup, suspected inflammatory bowel disease, and suspected tumors of the small bowel often require small bowel investigation.

While video capsule endoscopy (VCE) and computed tomography (CT) enteroclysis (CTE) are often the initial diagnostic modalities for suspected small bowel pathologies and can provide structural information of the small bowel mucosa, biopsy or therapy for the detected pathology could not be performed with VCE or CTE. In patients who require biopsy or therapy of the detected small bowel pathology, deep enteroscopy would be the procedure of choice in modern clinical practice before subjecting patient to surgery.

Diagnostic and therapeutic deep enteroscopy can be performed by balloon overtube assisted enteroscopy (eg, double balloon enteroscopy (DBE), single balloon enteroscopy (SBE) or spiral overtube assisted enteroscopy (SE). Despite the difference in equipment design of DBE, SBE, and SE, the concepts for small bowel intubation by pleating the intestine over the endoscope are the same behind these techniques. Depending on the location of the small bowel pathology reported by VCE or CTE, antegrade (oral route), retrograde (anal route), or combined antegrade and retrograde deep enteroscopy for total enteroscopy can be performed.

Conditions

  • Small Bowel Disease

Interventions

PROCEDURE

Motorized spiral enteroscopy (MSE)

Endoscopic Procedures MSE is a 1.6m enteroscope equipped with a single-use short spiral overtube propelled by a user-controlled motor contained in the handle of the endoscope. The endoscopist controls the left-right and up-down movements by the usual manuvers while the forward or backward advancement of the enteroscope would be contolled by a foot pedal that activates the spiral overtube rotation. Antegrade MSE, retrograde MSE, or combined antegrade and retrograde MSE would be performed as clinically indicated for diagnostic +/- therapeutic procedures.
