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

objectiveLaparoscopic transverse colectomy is challenging owing to technical difficulties in identifying an adequate dissection plane, ligating and dissecting lymph nodes around the middle colic vessels. One of the reasons for the technical difficulties is the complex relationship between the middle colic vein (MCV) and its tributary. So, defining the venous anatomy around the MCV before laparoscopic surgery seems important to avoid massive bleeding. The purpose of this study was to evaluate the depiction rate and variation of the MCV and its tributaries on three-dimensional CT angiography (3DCTA).

methodsThis study included 331 patients (203 males and 128 females) scheduled for laparoscopic surgery between June 2010 and April 2012. Most of the patients had gastric or colorectal cancer. Patients who needed emergency surgeries for obstruction or perforation were excluded. 3DCTA with an i.v. contrast medium was performed immediately following the administration of effervescent granules or room air insufflation. We assessed variations of the MCV tributaries using transaxial, multiplanar reconstructed images and volume-rendering images.

resultsThe MCV could be identified in all patients. The MCVs drained into the superior mesenteric vein in 62.5% of patients, gastrocolic trunk of Henle in 29.3% of patients, inferior mesenteric vein in 4.8% of patients, splenic vein in 2.7% of patients and jejunal vein in 0.6% of patients.

conclusion3DCTA is useful in evaluating the anatomic variants of the MCV in pre-operative planning for laparoscopic surgery. ADVANCES IN KNOWLEDGE: Use of 3DCTA for the recognition of the anatomic complexity around the MCV and its tributary plays an important role in pre-operative planning for optimal patient outcome.
