Currently, the treatment of anastomotic fistulas is primarily conservative or involves surgical repair. Platelet-rich plasma (PRP) contains high concentrations of platelets and is used to promote wound healing. However, the use of PRP in the treatment of anastomotic fistulas has rarely been reported.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>The patient was a 63\u00a0year-old man, Chinese and Asian. The patient underwent radical treatment for a malignant colon tumor in 2011. In 2014, he complained of persistent abdominal pain and was diagnosed with a malignant gastric tumor for which he underwent a subtotal (Billroth I) gastrectomy. After the surgery, an anastomotic fistula was observed. After more than 1\u00a0month of conservative treatment, the patient\u2019s anastomotic fistula still failed to heal; then, autologous PRP was attempted. PRP was prepared by centrifugation and activated into a gel state. The fistula was treated with PRP gel occlusion endoscopically, and a total of 3\u00a0mL was injected. One week after treatment, the fistula was healed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Diagnosis<\/jats:title>\n                    <jats:p>Anastomotic fistula after subtotal gastrectomy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Interventions<\/jats:title>\n                    <jats:p>Platelet-rich plasma (PRP) gel occluded anastomotic fistula under gastroscopy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Outcomes<\/jats:title>\n                    <jats:p>One week after PRP treatment, the closure of the fistula was observed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>PRP derived from the patient\u2019s own blood, offers advantages for healing intestinal fistulas that fail to respond to prolonged conservative therapy.
