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 surgery (MIS) for colorectal disease has well-known benefits, but many patients undergo open operations. When choosing an MIS approach, robotic technology may have benefits over traditional laparoscopy and is increasingly used. However, the broad adoption of MIS, and specifically robotics, across colorectal operations has not been well described. Our primary hypothesis is that rates of MIS in colorectal surgery are increasing, with different contributions of robotics to abdominal and pelvic colorectal operations.

methodsRates of MIS colorectal operations are described using a prospective cohort of elective colorectal operations at hospitals in the Surgical Care Outcomes Assessment Program (SCOAP) from 2011 to 2018. The main outcome was proportion of cases approached using open, laparoscopic, and robotic surgery. Factors associated with increased use of MIS approaches were described.

resultsAcross 21,423 elective colorectal operations, rates for MIS (laparoscopic or robotic surgery) increased from 44% in 2011 to 75% in 2018 (p < 0.001). Approaches for abdominal operations (n = 12,493) changed from 2 to 11% robotic, 43 to 63% laparoscopic, and 56 to 26% open (p < 0.001). Approaches for pelvic operations (n = 8930) changed from 3 to 33% robotic, 40 to 42% laparoscopic, and 57 to 24% open(p < 0.001). These trends were similar for high-(100 + operations/year) and low-volume hospitals and surgeons.

conclusionsAt SCOAP hospitals, the majority of elective colorectal operations is now performed minimally invasively. The increase in the MIS approach is primarily driven by laparoscopy in abdominal procedures and robotics in pelvic procedures.
