Novel techniques of liver segmental and subsegmental pedicle anatomy from segment 1 to segment 8.
Article in World journal of gastrointestinal surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundLaparoscopic anatomical liver resection has become more challenging because some subsegmental Glissonean pedicles are hard to dissect. Here, we introduce how to dissect every (sub) segmental Glissonean pedicle from the first porta hepatis and perform standardized (sub) segmentectomy [from segment 1 (S1) to S8].
aimTo summarize our methods of laparoscopic anatomical segmental and subsegmental liver resection.
methodsThe Glisson sheath and liver capsule were separated along the Laennec membrane. The Glissonean pedicle could be isolated and transected with little or no parenchymal damage through this extra-Glissonean dissection approach. The basin of the (sub) segment was determined by the ischemia demarcation line or indocyanine green staining. The hepatic vein or intersegmental vein was also used to guide the plane of parenchymal transection.
resultsAll segmental or subsegmental pedicles or even the pedicle of the cone unit could be dissected along the Laennec membrane using our novel technique through the first porta hepatis. The dorsal branches of S8, the branches of S4a and the paracaval portion branches (b/c vein) of the caudate lobe were the most difficult to dissect.
conclusionThe novel techniques of liver segmental and subsegmental pedicle anatomy is feasible for laparoscopic liver resection and can help accurately guide (sub) segmentectomy from S1 to S8.
