Laparoscopic Anterior-Approach Right Posterior Sectionectomy for Huge Hepatocellular Carcinoma: Technique and Short-Term Outcomes.
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
backgroundLaparoscopic liver resection is technically demanding for hepatocellular carcinoma (HCC) ≥10 cm in the right liver. In open liver resection, the anterior approach is established for large right-lobe tumors because it avoids parenchymal compression during mobilization.
methodsAmong 799 minimally invasive liver resections performed between 2011 and 2025, four men (median age 72.5 years, range 60-84) with huge tumors (median diameter 11.5 cm, range 10-12) underwent laparoscopic (extended) RPS with an anterior approach. As the tumor bulk caused firm adhesion to the diaphragm and retroperitoneum, the right lobe was left in situ. Parenchymal transection was initiated caudally and progressed cranially along the right inferior vena cava. The specimen was detached only after the transection. Patients were placed in the left hemilateral decubitus position with French lithotomy, and clamp-crushing was used for transection.
resultsTwo standard and two extended RPSs were completed. The median operative time was 524 minutes (range 418-603), and blood loss was 80 mL (range 10-550); no transfusions were required. The median weight was 753.5 g (range 450-934). No Clavien-Dindo ≥IIIa complications occurred. The median postoperative stay was 11 days (range 9-16). All margins were negative.
conclusionsLaparoscopic anterior-approach RPS is feasible and safe for huge right posterior HCCs, enabling secure transection without mobilization and yielding favorable short-term outcomes.
