Summary

Intraoperative enteroscopy in Crohn's disease revealed mucosal inflammation often differs from external bowel changes. This endoscopic visualization aids surgeons in making more precise decisions, potentially limiting unnecessary bowel resection.

Area of Science:

  • Gastroenterology
  • Surgical Endoscopy
  • Inflammatory Bowel Disease

Background:

  • Crohn's disease management often involves surgical resection.
  • Assessing the extent of inflammation is crucial for surgical decision-making.
  • External serosal changes are sometimes used as indicators of underlying mucosal disease.

Purpose of the Study:

  • To compare the extent of mucosal inflammation with external bowel wall changes during surgery for Crohn's disease.
  • To evaluate the impact of intraoperative endoscopic findings on surgical management decisions.
  • To determine if external inflammatory signs reliably predict the need for resection.

Main Methods:

  • Intraoperative small bowel endoscopy was performed in 33 instances across 31 patients with Crohn's disease.

  • The extent of mucosal inflammation was correlated with external changes like serositis, fat-wrapping, and mural thickening.
  • The influence of endoscopic findings on surgical decisions was documented.

    • Main Results:

    • Mucosal inflammation was generally more extensive than serositis but less than mural thickening.
    • Fat-wrapping extent was comparable to mucositis.
    • In 8 of 23 reoperation/fistula/abscess cases, external changes were present without mucosal inflammation.
    • Endoscopic findings altered surgical plans in 20 of 33 procedures, often limiting resection.

    Conclusions:

    • External inflammatory changes in Crohn's disease are unreliable indicators of mucosal disease extent and resection needs.
    • Intraoperative enteroscopy provides direct visualization of the mucosa.
    • This visualization enables more precise surgical decisions, potentially reducing the extent of resection.
