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

The retroperitoneal intestinal vein-general circulation anastomotic pathway is referred to as a Retzius shunt; however, it is not a well-recognized condition. Here, we describe two patients with a Retzius shunt who underwent robot-assisted surgery for rectal cancer. The first case was an 81-year-old woman who had tested positive for fecal occult blood. A type 0-Is tumor was found in the middle rectum, and we used robot-assisted surgery for resection. Intraoperative findings included a dilated vein between the inferior mesenteric artery (IMA) and inferior mesenteric vein (IMV); further, computed tomography (CT) revealed flow into the inferior vena cava (IVC). We clipped the vein without major bleeding and the tumor-specific mesorectal excision was completed. Thereafter, we reviewed relevant literature and identified the structure to be a Retzius shunt. The second case was 77-year-old man with type 1 advanced cancer in the middle rectum who underwent robot-assisted surgery. In this case, we recognized the Retzius shunt on preoperative CT due to our experience with the first case and surgery was completed without any problems. Preoperative recognition of vascular malformations, such as the Retzius shunt by CT is critical to ensure the safety of robot-assisted surgery.
