Many people with Crohn's will need surgery at some point to remove damaged sections of intestine. Although surgery can improve symptoms, the disease often comes back near the join (anastomosis) where the bowel has been reconnected.\n\nSurgeons use different techniques to reconnect the bowel. One newer approach, called the Kono-S anastomosis, is designed to reduce the risk of Crohn's disease returning. Early results are promising, but it is still not fully understood why it may work better than traditional methods.\n\nThis project aims to explore how the bowel heals after surgery by looking at oxidative stress, a type of tissue damage caused by an imbalance of harmful molecules in the body. The investigators will focus on a protective protein called glutathione peroxidase-4 (GPX4), an anti-oxidative enzyme that reduces oxidized phospholipids in biomembranes.\n\nBy analysing tissue samples taken before and after surgery, the investigators will compare patients who had the Kono-S technique with those who had standard surgical joins. The investigators want to see whether differences in healing at a microscopic level could explain why some patients do better than others.\n\nThe findings from this study could:\n\n* Improve understanding of why Crohn's disease comes back after surgery.\n* Help surgeons choose the best technique for each patient.\n* Support the development of new treatments aimed at improving healing. Ultimately, this research aims to reduce the risk of disease recurrence and improve long-term outcomes for people living with Crohn's disease.",[62],"Chrohn's Disease",[64,65],"anastomotic healing,","GPX4","NOT_YET_RECRUITING","2026-08-17",{"date":69,"type":70},"2026-08-19","ACTUAL",{"date":72,"type":58},"2026-11",{"date":74,"type":58},"2027-11",{"name":5,"class":6},1]
