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

introductionRecent studies show contrasting data on the impact of laparoscopy on long-term complications such as the occurrence of small bowel obstruction (SBO) and incisional hernia (IH). The objective of the study was to assess the impact of the laparoscopic approach on the occurrence of SBO and IH after colorectal resection.

methodsTwo trained investigators independently searched MEDLINE, Embase, PubMed, and the Cochrane Central Register of clinical trials for studies comparing laparoscopy to open surgery for mid- to long-term outcomes after colorectal surgery. No language restriction was set. Sensitivity analyses for study design and quality, conversion rate, type of procedure (colon or rectal surgery), and length of follow-up were performed.

resultsEleven RCTs and 14 non-RCT comparative studies for a total of 6540 patients were included in the analysis. Laparoscopy was associated with a significant reduction in the occurrence of SBO (RR 0.57, [95 %CI 0.42-0.76], 16 trials) and IH (RR 0.60, [95 %CI 0.50-0.72], 19 trials). Sensitivity analysis including only RCTs confirmed the reduction in SBO (RR 0.58, [95 %CI 0.39-0.87], 8 trials), while the difference was close to significance for IH (RR 0.76, [95 %CI 0.56-1.03], 7 trials). Sensitivity analysis including only studies with conversion rate lower than 15 % showed a significant protective effect of laparoscopy for both SBO (RR 0.53, [95 %CI 0.37-0.77], 11 trials) and IH (RR 0.58, [95 %CI 0.47-0.72], 12 trials). No significant difference between laparoscopy and open surgery was found when the analysis was limited to studies with conversion rate >15 % (SBO: RR 0.60 [0.32-1.12], IH: RR 0.70 [0.46-1.06]). Length of follow-up did not substantially impact on results.

conclusionLaparoscopic surgery is associated with a significant reduction in both SBO and IH compared to the open approach. A low conversion rate in the laparoscopic group plays a key role for reduction in both SBO and IH.
