1 · What the graph read from it

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.

2 · The registry

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

INTRODUCTION AND

objectivesCurative resection of type IV hilar cholangiocarcinoma typically requires trisectionectomy, a procedure associated with high morbidity. The Taj Mahal hepatectomy, involving resection of segment IVb, V, and the caudate lobe, offers a parenchyma-preserving alternative.

methodsPatients with type IV hilar cholangiocarcinoma without vascular involvement are suitable candidates. A 59-year-old male with jaundice and 1-month weight loss underwent sequential percutaneous transhepatic biliary drainage (segment III and right posterior ducts) for elevated bilirubin (>30 mg/dL). Key steps included hepatoduodenal lymphadenectomy, distal bile duct division with frozen section, caudate mobilization via a left-sided approach, indocyanine green-guided segment IV resection with en bloc caudate lobectomy, and three separate cholangiojejunostomies.

resultsOperative time was 560 minutes with 300 mL blood loss. The postoperative course was uneventful, and the patient was discharged on day 8. Histopathology showed T2 moderately differentiated adenocarcinoma with negative margins and 14 tumor-free lymph nodes. At 11-month follow-up, the patient remained disease free. Four patients underwent this procedure over 12 months.

conclusionRobotic-modified Taj Mahal hepatectomy is a safe, feasible, parenchyma-preserving option for selected patients with type IV hilar cholangiocarcinoma.
