AL Lightner et al. Inflamm Bowel Dis 2022; 28: https://doi.org/10.1093/ibd/izab126. Is Intestinal Diversion an Effective Treatment for Distal Crohn’s Disease?

In this retrospective study (n=132 adults), the indications for surgery were medically refractory proctocolitis with perianal disease (n = 59; 45%), perianal disease alone (n = 24; 18%), colitis (n = 37; 28%), proctitis (n = 4; 3%), proctocolitis alone (n = 4; 3%), and ileitis with perianal disease (n = 4; 3%)

Key findings :

• The clinical and endoscopic response to diversion was 43.2% (n = 57) and 23.9% (n = 16).
• At a median follow-up of 35.3 months, 25 patients (19%) had improved and had ileostomy reversal, but 86 (65%) did not improve, with 50 (38%) undergoing total proctocolectomy for persistent symptoms
• Also, 24% experienced stoma morbidity (peristomal abscess, hernia or prolapse)

My take: In this study of adults with distal Crohn’s disease, a “temporary” stoma/fecal diversion was only temporary in ~20%. This information is quite important for patients when considering this treatment option.
