Laparoscopic Tracer Technique for Liver Lymphatic Drainage by Injecting Indocyanine Green into the Glisson Pedicle.

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
backgroundCurrently, an effective tracer technique for lymphatic drainage during laparoscopic surgery has not been established. This study aimed to elucidate a new fluorescence, imaging technique targeting the hepatic lymphatic drainage area, using indocyanine green (ICG).
methodsA patient diagnosed with intrahepatic cholangiocarcinoma (ICC) located in segment 8 of the liver was injected with ICG into the connective tissue of the Glisson pedicle supplied by the lesion's liver segment, avoiding the bile duct, portal vein, and hepatic artery. This was performed under the guidance of laparoscopic ultrasonographic localization to trace the lymph nodes.
resultsThe lymphatic drainage area traced intraoperatively by ICG was consistent with the definition of the right regional lymph nodes for ICC. The lymph nodes were dissected, followed by addition of a fluorescence tracer.
conclusionsMastering intraoperative ultrasonic puncture technology can enable effective and accurate tracing of the lymph nodes of the liver segment where the lesion is located. However, the technical standards for this methodology need to be established through further studies.
