New classification system for radical rectal cancer surgery based on membrane anatomy.

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
backgroundTotal mesorectal excision along the "holy plane" is the only radical surgery for rectal cancer, regardless of tumor size, localization or even tumor stage. However, according to the concept of membrane anatomy, multiple fascial spaces around the rectum could be used as the surgical plane to achieve radical resection.
aimTo propose a new membrane anatomical and staging-oriented classification system for tailoring the radicality during rectal cancer surgery.
methodsA three-dimensional template of the member anatomy of the pelvis was established, and the existing anatomical nomenclatures were clarified by cadaveric dissection study and laparoscopic surgical observation. Then, we suggested a new and simple classification system for rectal cancer surgery. For simplification, the classification was based only on the lateral extent of resection.
resultsThe fascia propria of the rectum, urogenital fascia, vesicohypogastric fascia and parietal fascia lie side by side around the rectum and form three spaces (medial, middle and lateral), and blood vessels and nerves are precisely positioned in the fascia or space. Three types of radical surgery for rectal cancer are described, as are a few subtypes that consider nerve preservation. The surgical planes of the proposed radical surgeries (types A, B and C) correspond exactly to the medial, middle, and lateral spaces, respectively.
conclusionThree types of radical surgery can be precisely defined based on membrane anatomy, including nerve-sparing procedures. Our classification system may offer an optimal tool for tailoring rectal cancer surgery.
