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.

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.

Abstract

objectiveThe expansion of Minimally Invasive Surgery (MIS) has been exponential since the introduction of laparoscopic surgery in the late 1980s. This shift in operative technique has led many to believe that surgery residents are not developing the skills needed to adequately perform open operations.

methodsWe performed a retrospective review of the Accreditation Council for Graduating Medical Education national operative case log database of general surgery residents from January 2003 to December 2019. We compared the open vs. laparoscopic case numbers for six different operations, including cholecystectomy, appendectomy, inguinal hernia repair, colectomy, gastrectomy, and Nissen fundoplication. The Cochran-Armitage test was used to assess the linear trend in the procedures performed.

resultsTotal average residency case volumes for the procedures studied have increased from 270 to 368 (36%) over the 16-year period with MIS steadily representing a greater proportion of these cases. From 2003 to 2018, MIS representation increased in all studied procedures: cholecystectomy (88% to 94%, p = 0.048), inguinal hernia repair (20% to 47%, p ≤ 0.001), appendectomy (38% to 93%, p ≤ 0.001), colectomy (8% to 43%, p ≤ 0.001), gastrectomy (43% to 84%, p = 0.048), and Nissen (71% to 91%, p = 0.21).

conclusionWhile the overall operative volume has increased nationally for surgical residents, the representation of open cases has steadily declined since the advent of MIS. The experience needed in open surgery during resident training is still to be determined and may be necessary now that laparoscopy is progressively replacing open operations.
