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

backgroundMinimally invasive right hemicolectomy for cancer with complete mesocolic excision is a difficult procedure to perform. The aim of this single-center prospective study was to evaluate whether preoperative angio-CT colonography (A-CTC) improved the quality of lymph node dissection during this surgery.

methodsAll patients undergoing elective minimally invasive right hemicolectomy for colon adenocarcinoma with complete mesocolic excision between 01/2020 and 12/2023 have been prospectively included. The primary endpoint was the number of lymph nodes examined in the surgical specimen, including the total number of lymph nodes and the percentage of patients with at least 12 lymph nodes examined. Secondary endpoints included operating time, intraoperative complications, overall postoperative morbidity, and length of hospital stay. A propensity score was constructed with groups matched 3:1 using nearest neighbor matching based on the propensity score.

resultsOf the 161 patients included, 44 had A-CTC (27%) and 117 had conventional CT scans. After propensity score matching, patients in the A-CTC group had significantly more lymph nodes on the surgical specimen (24 vs. 20, p = 0.006) and a better quality of lymph node dissection (≥ 12 examined lymph nodes: 100% vs. 87%, p < 0.001). Median operative times were similar between the two groups (184 vs. 180 min, p = 0.07), but two patients (2%) in the conventional CT group experienced an intraoperative bleeding complication. Postoperative morbidity and length of hospital stay were comparable.

conclusionsPreoperative 3D reconstruction of vascular anatomy with A-CTC is useful and improves the quality of lymph node dissection during minimally invasive right hemicolectomy for cancer.
