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

backgroundUntil randomized trials mature, large database analyses assist in determining the role of robotics in colorectal surgery. ACS NSQIP database coding now allows differentiation between laparoscopic (LC) and robotic (RC) colorectal procedures. The purpose of this study was to compare LC and RC outcomes by analyzing the ACS NSQIP database.

methodsThe ACS NSQIP database was queried to identify patients who had undergone RC and LC during 2013. Demographic characteristics, intraoperative data, and postoperative outcomes were identified. Using propensity score matching, abdominal and pelvic colorectal operative and postoperative outcomes were analyzed.

resultsA total of 11,477 cases were identified. In the abdomen, 7790 LC and 299 RC cases were identified, and 2057 LC and 331 RC cases were identified in the pelvis. There were significant differences in operative time, conversion to an open procedure in the pelvis, and hospital length of stay. RC operative times were significantly longer in both abdominal and pelvic cases. Conversion rates in the pelvis were less for RC when compared to LC--10.0 and 13.7%, respectively (p = 0.01). Hospital length of stay was significantly shorter for RC abdominal cases than for LC abdominal cases (4.3 vs. 5.3 days, p < 0.001) and for RC pelvic cases when compared to LC pelvic cases (4.5 vs. 5.3 days, p < 0.001). There were no significant differences in surgical site infection (SSI), organ/space SSI, wound complications, anastomotic leak, sepsis/shock, or need for reoperation within 30 days.

conclusionAs the robotic platform continues to grow in colorectal surgery and as technical upgrades continue to advance, comparison of outcomes requires continuous reevaluation. This study demonstrated that robotic operations have longer operative times, decreased hospital length of stay, and decreased rates of conversion to open in the pelvis. These findings warrant continued evaluation of the role of minimally invasive technical upgrades in colorectal surgery.
