Laparoscopic versus open parenchymal sparing liver resections for high tumour burden colorectal liver metastases: a propensity score matched analysis.
Article in Surgical endoscopy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLaparoscopic liver resection (LLR) has proved effective in the treatment of oligometastatic disease (1 or 2 colorectal liver metastases CRLM) with similar long-term outcomes and improved short-term results compared to open liver resection (OLR). Feasibility of parenchymal sparing LLR for high tumour burden diseases is largely unknown. Aim of the study was to compare short and long-term results of LLR and OLR in patients with ≥ 3 CRLM.
methodsPatients who underwent first LR of at least two different segments for ≥ 3 CRLM between 01/2012 and 12/2021 were analysed. Propensity score nearest-neighbour 1:1 matching was based on relevant prognostic factors.
results277 out of 673 patients fulfilled inclusion criteria (47 LLR and 230 OLR). After match two balanced groups of 47 patients with a similar mean number of CRLM (5 in LLR vs 6.5 in OLR, p = 0.170) were analysed. The rate of major hepatectomy was similar between the two group (10.6% OLR vs. 12.8% LLR). Mortality (2.1% OLR vs 0 LLR) and overall morbidity rates (34% OLR vs 23.4% LLR) were comparable. Length of stay (LOS) was shorter in the LLR group (5 vs 9 days, p = 0.001). No differences were observed in median overall (41.1 months OLR vs median not reached LLR) and disease-free survival (18.3 OLR vs 27.9 months LLR).
conclusionLaparoscopic approach should be considered in selected patients scheduled to parenchymal sparing LR for high tumour burden disease as associated to shorter LOS and similar postoperative and long-term outcomes compared to the open approach.
