Invasive inflammatory fibrotic polyp of the duodenum: A case report.
Article in World journal of gastrointestinal surgery, 2025. 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
backgroundAn inflammatory fibrotic polyp (IFP) of the gastrointestinal tract is generally considered benign and noninvasive. An IFP in the duodenum is very rare. Here we report the case of an aggressive and infiltrative duodenal IFP resembling a malignancy and the patient subsequently underwent surgery. To the best of our knowledge, this is the first case of duodenal IFP invading the subserosa. CASE SUMMARY: A 50-year-old female patient presented with recurrent epigastric pain for more than 1 month. Gastroscopy revealed a mass in the duodenal bulb involving the pylorus. Endoscopic ultrasound suggested that the lesion was a hypoechoic mass involving the muscularis propria, and duodenal bulb stromal tumor was considered based on abdominal computed tomography and gastric magnetic resonance imaging findings. A distal gastrectomy was subsequently performed. Based on the histopathology and immunohistochemical results, the lesion was finally diagnosed as duodenal IFP. The patient recovered well after surgery and had no recurrence at the 27-month follow-up.
conclusionThis duodenal IFP invading subserosa indicates that IFP has specific invasion characteristics, and accurate diagnosis is critical to avoid inadequate treatment.
