Effect of unplanned conversion to open surgery on resection margins and postoperative complications in minimally-invasive resection of colorectal liver metastases: A systematic review and meta-analysis with meta-regression.

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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Backgrounds/Aims: To evaluate the impact of unplanned conversion to open surgery on resection margin status and postoperative complications in patients undergoing minimally-invasive resection of colorectal liver metastases (CRLM). Methods: This study performed a proportion meta-analysis and meta-regression using random-effects modelling in accordance with PRISMA guidelines. Studies with at least 15 patients that reported conversion to open surgery in individuals receiving minimally-invasive CRLM resection were included. The association of unplanned conversion with postoperative outcomes was analyzed. Results: Eighty-six studies encompassing 18,138 patients were analyzed. The overall conversion rate was 5.8% (95% CI 5%-6.6%). Conversion was associated with improved R0 resection rates (coefficient: 2.167, Conclusions: Unplanned conversion to open may carry prognostic and oncological implications for minimally-invasive resection of CRLM. Although conversion due to bleeding and iatrogenic injury is routinely considered, conversion prompted by technical difficulties or oncological concerns should not be considered failure, as it may be associated with improved patient outcomes.
