Total ureteral replacement with a small intestinal graft as a reconstructive stage of combined treatment for recurrent colorectal cancer: case report.

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: We present a clinical case highlighting total ureteral replacement with a small intestinal graft as a key reconstructive component in the surgical management of recurrent colorectal cancer. Case description: A 48-year-old female patient previously underwent low anterior rectal resection with D2 lymph node dissection (pT2N0M0, 2018). Four years later, she presented with clinical signs of obstruction in the middle third of the left ureter. Imaging revealed a mass involving the ureteral wall and left psoas muscle, alongside left adnexal abnormalities. Surgical treatment was staged and included en bloc resection of the recurrent mass with removal of the left ureter, adnexectomy, and segmental colectomy. In the remission phase, ureteral reconstruction was performed using a small intestinal graft, followed by transverse colon mobilization and the creation of a stapled transverse-rectal anastomosis. Discussion: This case illustrates how timely, organ-preserving reconstruction - integrated into comprehensive oncological surgery - can improve both survival and quality of life in patients with locally advanced recurrent rectal cancer.
