Endoscopic Balloon Dilatation Combined With PRP Injection in Colonic Stenosis in Crohn's Disease

The aim was to investigate whether endoscopic balloon dilatation combined with PRP injection can help prevent or prolong restenosis in patients with Crohn\'s disease with colonic stenosis, and to explore the concentration of PRP. The study was a single-center, randomized, non-controlled study. Experimental group of patients underwent endoscopic balloon dilation and submucosal injection of PRP (PRP prepared by the blood transfusion department of our hospital) at the wound edge, historical control was used, and the patients included in the study were randomly divided into high concentration group and low concentration group.
