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

backgroundWhile minimally invasive liver surgery has been increasingly adopted at least for minor resections, experience with robotic liver surgery is still limited to a few highly specialized centers. Due to the fear of abdominal adhesions, a history of prior surgeries is still used as an argument for open approaches.

methodsClinical data of all consecutive robotic resections at our center, using the da Vinci Xi surgical system, between April, 2018 and December, 2020, were collected and analyzed as part of a prospective, post-marketing observational study (DRKS00017229). Prior abdominal surgeries were specified according to the surgical approach and localization. Baseline and perioperative outcome criteria were compared between patients with prior surgeries (PS) and patients with no prior surgeries (NPS) in univariate and multivariate analyses.

resultsOut of the 126 patients undergoing robotic liver resections, 59% had a history of abdominal surgeries, which were most often colorectal resections (28%) followed by liver resections (20%). Patients with NPS were more likely to undergo robotic liver resection for hepatocellular carcinoma or benign tumors, and to have underlying liver cirrhosis when compared to patients with PS. Other baseline characteristics as well as the extent of resections were similar. Duration of surgery (258 min), conversion rates (6%), and postoperative complications rates (21% Clavien-Dindo ≥ 3) showed no differences between NPS and PS. A subgroup of patients with a history of prior liver surgery showed a longer duration of surgery in univariate analysis. However, this was not confirmed in multivariate analysis which instead revealed tumor entity and liver cirrhosis as independently correlated with duration of surgery.

conclusionsWe propose robotic liver resection to be safe and feasible, including in patients with prior abdominal surgeries. Each patient should be evaluated for a minimally invasive procedure regardless of a history of previous operations.
