Capsule endoscopy is safe for evaluating small bowel obstruction and strictures. While capsule retention can indicate a surgical lesion, it does not contraindicate the procedure, aiding diagnosis and treatment planning.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Diagnostic Imaging

Background:

  • Capsule endoscopy excels in diagnosing obscure GI bleeding and Crohn's disease.
  • Small bowel obstruction and strictures are often considered contraindications for capsule endoscopy.
  • This study reassesses the safety and efficacy of capsule endoscopy in these scenarios.

Purpose of the Study:

  • To evaluate the safety and efficacy of capsule endoscopy in patients with suspected small bowel obstruction or strictures.
  • To challenge the conventional contraindication of capsule endoscopy in cases of small bowel obstruction.

Main Methods:

  • Retrospective chart review of 568 capsule endoscopy cases.
  • Selection of 19 cases with suspected small bowel obstruction (symptoms alone or with abnormal radiographs).

Main Results:

  • Capsule endoscopy provided a definitive diagnosis in 26% of cases (5/19), identifying Crohn's strictures, NSAID-induced strictures, radiation-induced strictures, and MALT lymphoma.
  • Capsule retention occurred in 4 cases proximal to strictures, leading to elective resection without complications.
  • No acute small bowel obstruction was caused by capsule administration.

Conclusions:

  • Capsule endoscopy is a safe tool for identifying the cause and location of small bowel obstructions.
  • Small bowel obstruction or strictures are not absolute contraindications for capsule endoscopy.
  • Capsule retention can signify a surgical lesion, guiding treatment decisions.
