Investigation of the regional lymph nodes in left-sided pancreas tumors by intraoperative identification using indocyanine green fluorescence imaging.

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
purposeTo identify the regional lymph nodes (LNs) in patients with left-sided pancreatic tumors using intraoperative indocyanine green fluorescence imaging (ICGFI).
methodsThe lymphatic flow was evaluated using the ICGFI in 15 patients with left-sided pancreatic tumors. Indocyanine green was administered locally, near the tumor, intraoperatively.
resultsThe distribution of ICGFI-positive lymph node stations differed according to the distance between the left side of the portal vein and the right side of the tumor (DPT). Patients with a DPT ≤ 71 mm (Group A, n = 10) and those with a DPT ≥ 72 mm (Group B, n = 5) showed different lymphatic drainage patterns. In Group A, the frequencies of positive LN stations detected by ICGFI were as follows: stations 7, 8, 9, 11, 14, and 18 had rates of 20%, 70%, 30%, 60%, 70%, and 20%, respectively. In contrast, in Group B, stations 10, 11, and 14 had rates of 40%, 80%, and 20%, respectively, with no observations at stations 7, 8, and 9. A statistically significant difference was observed between the two groups at station 8 (70% vs. 0%; p = 0.03).
conclusionsICGFI may provide useful anatomical insights into the lymphatic drainage pathways of left-sided pancreatic tumors and serve as a basis for future studies evaluating tailored lymphadenectomy strategies.
