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

backgroundThe use of transanal laparoscopic access to completely avoid abdominal wall incisions represents the most current evolution in minimally invasive surgery. The combination of single-site surgery and natural orifice transluminal endoscopic surgery (NOTES™) can be used for totally transanal laparoendoscopic pull-through colectomy with J-pouch creation (TLPC-J). The aim of the present study was to provide evidence for the feasibility of TLPC-J in adult human cadavers.

methodsTLPC-J was performed in six fresh adult human cadavers. The procedure involved endorectal submucosal dissection from 1 cm above the dentate line to a point above the peritoneal reflection, where the rectal muscle was divided circumferentially. The edge of the mucosal cuff was closed distally in order to prevent fecal contamination and the endorectal tube was placed back into the abdomen. A Triport+™ or QuadPort+™ system was introduced transanally, and it served as a multiport device (MD). Resection of the entire colon, mobilization of the distal ileal segment, and extracorporeal suture of the ileal J-loop were performed via the transanal approach. The J-pouch was created using Endo GIA™. After removal of the MD, the J-pouch was sutured to the rectal wall.

resultsTLPC-J was performed in all cadavers, with a mean operation duration of 236 ± 22 min. Conversion to either transabdominal laparoscopy or laparotomy was not required in any of the cadavers. No bowel perforation or damage to other organs was observed. The use of a curved endoscope greatly facilitated visualization during transanal laparoscopic dissection for partial and total colectomy, making the procedure feasible. All specimens were retrieved through the anus, eliminating the need for additional transabdominal incisions.

conclusionsTLPC-J was technically feasible in adult human cadavers, and abdominal wall incisions were not required. However, clinical studies are needed to determine its feasibility in living adults.
