Sigmoid intussusception from submucosal lipoma in an adolescent.

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
Colo-colic intussusception secondary to a submucosal lipoma is exceedingly rare, particularly in adolescents, and presents significant diagnostic and management challenges. A 16-year-old male presented with a 5-day history of left lower quadrant pain, nausea, vomiting, and currant jelly stool. Abdominal ultrasound identified a left iliac fossa mass, and contrast-enhanced computed tomography confirmed a submucosal lipoma with a 10 cm colo-colic intussusception and pelvic free fluid. Conservative management via contrast enema and sigmoidoscopy failed due to mucosal oedema and ulceration, and open sigmoid colectomy was performed. Histopathology confirmed a 32 mm mature lipoma as the lead point with no evidence of malignancy. The patient recovered well and was discharged on postoperative day ten. This case highlights that colo-colic intussusception in adolescents should not be presumed idiopathic. A pathological lead point must always be excluded, and when conservative measures fail, timely surgical resection ensures definitive treatment and favourable outcomes.
