Confocal chromolaser endomicroscopy: a supplemental diagnostic tool prior to transanal endoscopic microsurgery of rectal tumors?

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
purposeDue to diagnostic advancements, preoperative staging of rectal tumors was significantly improved. However, difficulties in obtaining accurate results can sometimes be observed in the staging of adenomas and early rectal carcinomas (pT1/2). The aim of this study was to test if confocal chromolaser endomicroscopy (cCLEM) can help minimize this diagnostic gap.
methodscCLEM generates optical transversal sections at x1,000 magnification and allows for evaluation of the mucosal microarchitecture and differentiation of normal mucosa from adenomas and carcinomas. Cases with conflicting preoperative findings (adenoma vs. > or =uT2 categories), undetectable tumors after inadequate (R1/RX) snare polypectomy of carcinomas, and extremely flat adenoma areas were studied.
resultsBy cCLEM, in > or =uT2 carcinomas with an adenoma histology, malignoma-suspicious areas were identified and selected biopsies were done. In addition, re-epithelialized polypectomy areas of carcinomas were visualized and targeted reoperations could be carried out. Furthermore, the dignity and extension of extremely flat adenomas were determined and marked by clips for additional therapy.
conclusionsIn cases with rectal tumors, conflicting or unclear findings, and flat extending adenomas, the utilization of cCLEM should be considered. Especially in cases with early rectal carcinomas, unnecessary second operations and also recurrences can be minimized or even avoided by selective usage of cCLEM.
