A novel push-and-pull enteroscopy technique with a single-balloon was successful in completing ileocolonoscopies in patients who previously failed standard colonoscopy. This advanced endoscopic approach enables therapeutic interventions in challenging cases.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Medical Devices

Background:

  • Standard colonoscopy can be difficult or incomplete due to patient factors like female gender, low BMI, and prior pelvic surgery.
  • Previous attempts at ileocolonoscopy or endoscopic therapy with standard or pediatric colonoscopes had failed in these patients.

Purpose of the Study:

  • To evaluate the efficacy of a push-and-pull enteroscopy device with a single-balloon technique.
  • To assess the feasibility of performing ileocolonoscopy and therapeutic interventions in patients with previously unsuccessful colonoscopies.

Main Methods:

  • A push-and-pull enteroscopy device and single-balloon technique were used in 14 patients.
  • Patients had prior failed ileocolonoscopy or endoscopic therapy.
  • Indications included polyp investigation, obscure ileocecal inflammation, and anemia with positive fecal occult blood tests.

Main Results:

  • Ileocolonoscopy was successfully completed in all 14 patients without technical issues or complications.
  • Therapeutic endoscopic interventions were performed successfully, with one instance of bleeding.
  • Diagnoses included polyps (6), colon cancer (1), appendicitis with carcinoid tumor (1), ileocolitis (2), and anastomotic stenosis in Crohn's disease (1).

Conclusions:

  • The push-and-pull enteroscopy device with a single-balloon technique is effective for ileocolonoscopy.
  • This method allows for successful therapeutic interventions in patients with previously incomplete colonoscopies.
  • This advanced endoscopic approach offers a solution for challenging colonoscopy cases.
