Time lag between functional and structural lymphatic changes after lymphadenectomy: Insights from ICG lymphography and lymphatic ultrasound.
Observational study in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Postoperative lower limb lymphedema is a common complication following pelvic or para-aortic lymphadenectomy for gynecologic cancers. Early detection of lymphatic dysfunction is crucial, but the temporal relationship between functional and structural changes remains unclear. This prospective observational study aimed to compare indocyanine green (ICG) lymphography and lymphatic ultrasound findings at multiple time points in the early postoperative phase. We enrolled 23 patients (46 lower limbs) who underwent pelvic and/or para-aortic lymphadenectomy for gynecologic malignancies. Each patient underwent ICG lymphography and lymphatic ultrasound preoperatively and at 1, 3, and 9 months postoperatively. ICG patterns were categorized as linear, splash, or stardust, while lymphatic vessel dilation ≥0.3 mm was defined as abnormal on ultrasound. At least one abnormal ICG finding was observed in 52.2% of limbs, and abnormal ultrasound findings were present in 65.2%. Among limb-timepoints with abnormal ICG findings, lymphatic dilation on ultrasound was observed in 32.6% overall, increasing to 52.6% at 9 months postoperatively, indicating increasing concordance between functional and structural abnormalities over time. Splash patterns on ICG were often not accompanied by lymphatic dilation, whereas stardust patterns were more likely to coincide with structural changes, especially at 9 months. Skin thickness increased significantly in the medial and lateral lower leg regions in limbs with stardust patterns. Our findings demonstrate a temporal dissociation between functional abnormalities detected by ICG and structural changes detected by ultrasound, suggesting that ICG lymphography may be more sensitive in the early phase. The combined use of both modalities may help capture the continuum from early functional disturbance to later structural remodeling and inform the optimal timing of intervention.
