Outcomes and Long-Term Follow-Up of the Endoscopic Treatment of Strictures in Pediatric and Adult Patients with Inflammatory Bowel Disease (IBD)

responded to medical therapy. The localization and extent of the IENDO matched with the preoperatively performed MRI in all cases. In none of the cases mucosal involvement was found confirming the endoscopic impression. Conclusion: As earlier reported IENDO was only found in the bowel serosa and muscularis. MRI was found to be much more reliable in detecting IENDO compared to RSS, even combined with biopsy. Discussion: Although unproven, the cause of HECH in IENDO may be more mechanical (due to menstrual swelling of the ENDO deposits in the bowel wall causing tears in the overlying, but uninvolved, mucosa) than menstrual from mucosal deposits.
