Cure8 news brief
Postoperative recurrence after ileal resection is common in Crohn’s disease; understanding microbial changes linked to recurrence could help explain mechanisms and guide future biomarker development.

This study profiled mucosal biopsies at surgery and at follow-up endoscopy using 16S rRNA and ITS2 sequencing.
It highlights decreases in Faecalibacterium prausnitzii and increases in Akkermansia muciniphila associated with different patterns of endoscopic inflammation, reports much higher Malassezia prevalence in biopsies than fecal samples, and describes denser microbial network organization after surgery that breaks down with recurrence.
These findings improve understanding of post-surgical microbial changes but do not establish a ready-to-use clinical test: the authors note that predicting recurrence from surgery-time biopsies remains challenging with current models.

A predictive model for temporary stoma could influence surgical planning for people with Crohn’s disease, helping tailor decisions and expectations around intestinal resection.
This study suggests that regional differences in how often and how early advanced drugs are used didn’t change 10-year rates of surgery, hospitalization, or progression to complicated Crohn’s disease in this cohort.
This study suggests machine learning of stool microbiome data could eventually help distinguish IBD (especially Crohn’s) from healthy people and some other bowel or systemic conditions.
