Transitioning to the robotic era for perihilar cholangiocarcinoma: initial implementation and outcomes in a single center.
Article in Surgical endoscopy, 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 surgery for perihilar cholangiocarcinoma (pCCA) remains controversial owing to concerns regarding its technical feasibility and oncological adequacy. This study evaluated the early clinical outcomes of robotic surgery for pCCA during the institutional transition from open to robotic surgery.
methodsWe retrospectively analyzed 76 patients who underwent curative-intent resection for pCCA between January 2013 and January 2026. Of these patients, 66 underwent open surgery and 10 underwent robotic resection. Robotic surgery was introduced following extensive institutional experience with open and complex robotic hepatobiliary procedures. Perioperative outcomes, oncological parameters, and textbook outcome (TO) achievement were compared between the groups.
resultsR0 resection was achieved in 90.0% of robotic cases and 78.8% of open cases, and lymph node retrieval did not differ significantly between the groups. A higher proportion of patients in the robotic group attained TO (50.0% vs. 36.3%), although this trend did not reach statistical significance (P = 0.415). Major complications occurred in 30.0% of robotic cases and 25.7% of open cases (P = 0.780), and no 90-day mortality occurred in the robotic group. The length of hospital stay was similar despite the minimally invasive approach.
conclusionsRobotic surgery for pCCA is feasible and can be safely implemented following institutional validation in highly selected patients during the early implementation phase. While our early experience demonstrates acceptable perioperative outcomes, additional studies with larger cohorts and long-term follow-up are required to further evaluate the clinical utility and outcomes of robotic surgery and to define its role in pCCA.
