Abstract | BACKGROUD AND STUDY AIMS:
Esophageal stricture is a serious adverse event occurring after circular endoscopic submucosal dissection (ESD) involving the whole esophagus. However, there is still a lack of effectively preventive methods. The main purpose of this study is to evaluate the efficacy of application of acellularized dermis matrix (ADM) for the prevention of post-ESD esophageal stricture. The main objective of this study was to evaluate the use of decellularized dermal matrix (ADM) in the prevention of post-esophageal ESD strictures. PATIENTS AND METHODS: A pilot, single-center, prospective study was conducted. The study enrolled seven patients who had high-risks with extended resection of developing post-ESD esophageal stricture. After undergoing ESD, we attached different size of ADM patches to the mucosal defects using titanium clips then fixed with a metal mesh stent. The stent covered with metal mesh was removed at the median time of 27 days after the endoscopic procedure. Follow-up and repeated outpatient endoscopic screening were performed at appropriate scheduled times. RESULTS: The average longitudinal diameter of the resected specimens was 58.3 mm (range 38-90 mm). There were three patients developing strictures postoperatively at a mean time of 87 days (range 42-140). The median number of postoperative endoscopic balloon dilatation (EBD) in patients with stenosis was 2 (range 2-9). There were no deaths during a median follow-up period of 6 moths (range 1-12).
