Robotic Resection of Large Central Hepatic Tumor: Technique of Juxta-Hilar Tumor Dissection Off Anterior Glissonean Pedicle Sheath.
Article in Annals of surgical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRobotic liver surgery enables precise, parenchyma-sparing resection of centrally located hepatic tumors involving critical hilar structures. Focal nodular hyperplasia (FNH), although benign, may require resection in symptomatic or enlarging lesions. PATIENT AND
methodsA 24-year-old woman with biopsy-proven FNH presented with progressive right epigastric pain and tumor growth from 4.4 cm to 7.0 cm. Preoperative imaging demonstrated a centrally located lesion abutting the right anterior Glissonean pedicle without evidence of major vascular invasion, making preservation of uninvolved hepatic parenchyma a principal operative objective. She underwent robotic partial central hepatectomy (segments 4A, 4B, 5, and 8) with cholecystectomy, with intraoperative indocyanine green (ICG) cholangiography used to delineate biliary anatomy near the Glissonean pedicles. The robotic approach was selected to facilitate stable hilar exposure, meticulous juxta-hilar dissection, and controlled parenchymal transection adjacent to the biliary bifurcation while avoiding unnecessary extended hepatectomy. Selective vascular stapling was utilized only for isolated segmental inflow and outflow structures encountered during transection, while preserving the major hilar vasculature and surrounding functional liver parenchyma.
resultsThe procedure was completed in 3 h with 100 cc estimated blood loss and no complications. She was discharged on postoperative day 3. Final pathology confirmed complete resection, and at 1-year follow-up, she remained symptom-free with no evidence of recurrence.
conclusionsThis case highlights the feasibility of robotic central parenchyma-sparing hepatectomy for lesions in close proximity to critical hilar structures, demonstrating how enhanced robotic dexterity, stable visualization, and fluorescence guidance can facilitate safe dissection and excellent perioperative outcomes in anatomically challenging tumors.
