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

aimTo review the currently available literature comparing laparoscopic to open resection of hepatocellular carcinoma (HCC) in patients with known liver cirrhosis.

methodsA literature search of MEDLINE, EMBASE, and Cochrane databases was conducted. The search terms used included (laparoscopic OR laparoscopy) AND (hepatic or liver) AND (surgery or resection) AND "hepatocellular carcinoma" AND (cirrhosis or cirrhotic). Furthermore, to widen the search, we also used the "related articles" section. Studies reporting a comparison of outcomes and methods of open vs laparoscopic hepatic resection for HCC in patients with liver cirrhosis were included. Meta-analysis of results was performed using a random effects model to compute relative risk (RR) and for dichotomous variables and standard mean differences (SMD) for continuous variables.

resultsA total of 420 patients from 4 cohort studies were included in final analysis. Patients undergoing laparoscopic procedures had statistically less blood loss compared to the open cohort, SMD of -1.01 (95%CI: -1.23-0.79), P < 0.001, with a reduced risk of transfusion, RR = 0.19 (95%CI: 0.09-0.38), P < 0.001. A wider clearance at tumour resection margins was achieved following a laparoscopic approach, SMD of 0.34 (95%CI: 0.08-0.60), P = 0.011. No significant difference was noted between laparoscopic and open resection operative times, SMD of -0.15 (95%CI: 0.35-0.05), P = 0.142. The overall RR of suffering from postoperative morbidity is 0.25 in favour of the open surgery cohort (95%CI: 0.17-0.37), P < 0.001. Patients under-going laparoscopic surgery had significantly shorter length of stays in hospital compared to the open cohort, SMD of -0.53 (95%CI: -0.73 to -0.32), P < 0.001.

conclusionThis review suggests that laparoscopic resection of hepatocellular carcinoma in patients with cirrhosis is safe and may provide improved patient outcomes when compared to the open technique.
