Case Report: Endoscopic removal of a giant complex gastric trichobezoar: an alternative strategy using combined techniques.

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
Background: Giant gastric trichobezoar is a rare foreign body resulting from chronic hair ingestion and may lead to serious complications, including obstruction, perforation, and malnutrition. Conventional endoscopic removal often fails due to its large size, smooth, elastic surface, and tensile strength. Therefore, surgery is often the standard treatment. In this report, we discuss the case of a girl with a giant trichobezoar containing cotton threads, which was successfully removed following forceps-assisted mechanical fragmentation and transparent cap-assisted extraction. Case summary: A 7-year-old girl with a 5-year history of trichophagia presented with abdominal pain, distension, palpable mass, and iron-deficiency anemia. Imaging and endoscopy revealed a 12 cm × 6 cm gastric trichobezoar. As surgery was declined, endoscopic removal under general anesthesia was performed. The procedure used high-power electrocoagulation (EndoCut/Forced Coag mode) to segment the dense bezoar, followed by piecemeal extraction with forceps and cap-assisted removal to prevent cardia laceration and esophageal injury. The trichobezoar was successfully removed without mucosal injury, and the patient was discharged 4 days after the endoscopic procedure with complete resolution of symptoms. Conclusions: With strict patient selection, multidisciplinary teamwork, and adequate expertise and equipment, endoscopic treatment may offer a minimally invasive alternative to the surgical removal of giant gastric trichobezoars in selected pediatric cases. Psychological support is also important to address underlying behavioral factors that may lead to recurrence.
