Platelet-rich plasma for the treatment of postoperative anastomotic fistula of the gastrointestinal tract: a case report.
Article in Frontiers in pharmacology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Anastomotic fistulas are a possible complication of local digestive tract resections, and their main symptoms include abdominal pain, peritonitis, and infections. 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. Case presentation: The patient was a 63 year-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 month of conservative treatment, the patient's 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 mL was injected. One week after treatment, the fistula was healed. Diagnosis: Anastomotic fistula after subtotal gastrectomy. Interventions: Platelet-rich plasma (PRP) gel occluded anastomotic fistula under gastroscopy. Outcomes: One week after PRP treatment, the closure of the fistula was observed. Conclusion: PRP derived from the patient's own blood, offers advantages for healing intestinal fistulas that fail to respond to prolonged conservative therapy. Injecting PRP gel directly into these fistulas promotes tissue regeneration and closure.
