Adenocarcinoma below stapled ileoanal anastomosis after restorative proctocolectomy for ulcerative colitis.

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
A case of adenocarcinoma arising in a 39-year-old patient after restorative proctocolectomy is reported. The patient underwent an ileal pouch-anal anastomosis with double-stapled technique for severe ulcerative colitis 18 years earlier, without evidence of associated neoplasm or dysplasia in operative specimen. After endoscopic diagnosis of adenocarcinoma, the patient was submitted to excision of the pouch and permanent ileostomy, followed by combined radiotherapy and chemotherapy. Pathology showed an AJCC stage III moderately differentiated mucinous adenocarcinoma. The patient died 24 months after the operation, due to cancer progression. There are 50 reported cases in the indexed medical literature of carcinoma arisen after ileal pouch-anal anastomosis for ulcerative colitis. Twenty-five out of these arose after mucosectomy and hand-sewn anastomosis, and 25 after stapling technique. Furthermore, in 48% of the patients, dysplasia or cancer was already present at the time of the colectomy. The increase of reported cases suggests a routine long-term endoscopic surveillance in patients with long-standing ileal pouches, especially in presence of dysplasia or cancer in the proctocolectomy specimen.
