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 aims of the present study were to demonstrate the anatomical change of superior mesenteric vein (SMV) branches and to show how the Cattell Braasch maneuver facilitates a safer ligation of these venous branches during a pancreatoduodenectomy (PD).

methodsBetween January 2010 and December 2019, 97 patients with peripancreatic tumors underwent pancreatectomy. We retrospectively reviewed preoperative triple-phase enhanced computed tomography (CT) images and analyzed variations in SMV branches. Anatomical changes in SMV branches after the Cattell Braasch technique were observed using our operation video and illustrations.

resultsThe first jejunal vein (J1v) in 75% of patients ran posterior to the superior mesenteric artery (SMA), while the remainder (25%) ran anterior to it. The inferior pancreatoduodenal vein (IPDV) was preoperatively detected in 91% of patients. The IPDV drained into the J1v in 74% of patients and into the SMV in 37%. After the Cattell Braasch maneuver, the J1v which ran posterior to the SMA now was found to lie to the right anterolateral side the SMA and the visualization of both the J1v and the IPDV were much more clearly visualized.

conclusionsThe most frequent venous variation was the IPDV draining into the J1v posterior to the SMA. After the Cattell Braasch maneuver, the IPDV was now located to the right anterolateral anterior aspect of the SMA which facilitates its visualization and should allow a safer ligation.
