1 · What the graph read from it

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.

2 · The registry

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

backgroundIn patients with ultralow rectal cancer, surgical resection of the tumor without impairing sphincter function remains a technical challenge. The purpose of this study was to describe a new technique of transanal natural orifice specimen extraction (NOSE) surgery using our independently developed devices, aiming to achieve precise cancer resection and preserve sphincter function in patients with ultralow rectal cancer.

methodsPrecision functional sphincter-preserving surgery (PPS) was performed on nineteen patients with ultralow rectal cancer between June 2019 and April 2020. With the help of our independently developed devices, surgeons directly and accurately removed the lower edge of the tumor and retained healthy rectal tissue on the nontumorous side. Hand-sewn anastomosis with a mattress suture was used to achieve sturdy anastomosis. Preoperative baseline characteristics, operative details, 90-day postoperative complications, costs, and anal function score at 6 months after surgery were documented.

resultsNineteen ultralow rectal cancer patients with a median distance to the dentate line of 2.0 cm successfully underwent PPS without serious postoperative complications. Six out of nineteen patients (31.6%) received a prophylactic stoma. The average cost was 62164.1 yuan. At 6 months after surgery, the average Wexner anal function score and the average Vaizey score were both 3 points.

conclusionsPPS can be employed to precisely resect rectal tumors and preserve sphincter function in ultralow rectal cancer patients. The use of our devices enhanced surgical efficiency, reduced the need for prophylactic stoma, reduced surgery-related costs, and prevented abdominal surgical incisions.
