Hand-assisted versus straight laparoscopy for colorectal surgery - a systematic review and meta-analysis.
Synthesis in International journal of colorectal disease, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeHand-assisted laparoscopic surgery (HALS) is an alternative to straight laparoscopy (LAP) in colorectal surgery. Many studies have compared the two in terms of efficacy, complications, and outcomes. This meta-analysis aims to uncover if there are any significant differences in conversion rates, operative times, body mass index (BMI), incision lengths, intraoperative and postoperative complications, and length of stay.
methodsComprehensive searches were performed on databases from their respective inceptions to 16 December 2021, with a manual search performed through Scopus. Randomized controlled trials (RCTs), cohort studies, and case series involving more than 10 patients were included.
resultsA total of 47 studies were found fitting the inclusion criteria, with 5 RCTs, 41 cohort studies, and 1 case series. Hand-assisted laparoscopic surgery was associated with lower conversion rates (odds ratio [OR] 0.41, 95%CI 0.28-0.60, p < 0.00001), shorter operative times (Mean Difference [MD] - 8.32 min, 95%CI - 14.05- - 2.59, p = 0.004), and higher BMI (MD 0.79, 95%CI 0.46-1.13, p < 0.00001), but it was also associated with longer incision lengths (MD 2.19 cm, 95%CI 1.66-2.73 cm, p < 0.00001), and higher postoperative complication rates (OR 1.15, 95%CI 1.06-1.24, p = 0.0004). Length of stay was not different in HALS as compared to Lap (MD 0.16 days, 95%CI - 0.06-0.38 days, p = 0.16, and intraoperative complications were the same between both techniques.
conclusionsHand-assisted laparoscopy is a suitable alternative to straight laparoscopy with benefits and risks. While there are many cohort studies comparing HALS and LAP, more RCTs would be needed for a better quality of evidence.
