Submucosal injection of platelet-rich plasma in endoscopic resection of large sessile lesions.
World Journal of Gastrointestinal Endoscopy 2018 November 17
AIM: To prospectively evaluate the efficacy of submucosal injection of platelet-rich plasma (PRP) on endoscopic resection of large sessile lesions.
METHODS: Eleven patients were submitted to endoscopic mucosal resection (EMR) with prior injection of PRP, obtained at the time of endoscopy. Patients were followed during 1 mo. The incidence of adverse events (delayed bleeding or perforation) and the percentage of mucosal healing (MHR) after 4 wk were registered.
RESULTS: EMR was performed in 11 lesions (46.4 mm ± 4 mm, range 40-70 mm). Delayed bleeding or perforation was not observed in any patient. Mean ulcerated area at baseline was 22.7 cm2 ± 11.7 cm2 whereas at week 4 were 2.9 cm2 ± 1.5 cm2 . Patients treated with PRP showed a very high MHR after 4 wk (87.5%).
CONCLUSION: PRP is an easy-to-obtain solution with proven and favourable biological activities that could be used in advanced endoscopic resection.
