Left extended hepatectomy (H123458-B) versus right extended hepatectomy (H145678-B) for hilar cholangiocarcinoma: A single center comparative analysis of surgical outcomes and survival.

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
Backgrounds/Aims: Surgical resection is the only curative treatment for cholangiocarcinoma. In selected cases, extended hepatectomies, including right extended hepatectomy (REH; H145678-B) and left extended hepatectomy (LEH; H123458-B), are required. This study compares perioperative outcomes and long-term survival between LEH and REH. Methods: We retrospectively reviewed prospectively maintained data for all patients who underwent extended hepatectomies for hilar cholangiocarcinoma at a single institution between 2016 and 2022. Perioperative metrics and long-term outcomes were compared between groups. Results: Ten patients underwent LEH and 12 underwent REH. Future liver remnant was significantly greater in the LEH group (41% vs. 30%), and fewer LEH patients required volume manipulation (20% vs. 58%). Rates of major vascular resection were similar (LEH: 50% vs. REH: 58%). No patients in the LEH group developed post-hepatectomy liver failure (PHLF), compared to 41% in the REH group ( Conclusions: LEH may offer a superior safety profile, with lower PHLF incidence and shorter hospital stays compared to REH, while achieving similar oncologic outcomes. In anatomically suitable cases, LEH should be considered a potentially safer option for hilar cholangiocarcinoma.
