Adjuvant use of fibrin glue in the fistula tract may promote healing in low-output enterocutaneous fistulas. However, there are only few studies that report autologous glue application in a larger patient group or clinical-controlled studies in this setting. The aim of this study was to investigate the efficacy and safety of autologous platelet-rich fibrin glue (PRFG) in the treatment of low-output digestive fistulas and compare them with conservative management without the use of adjuvant application of FG into the fistulous tract.
