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

backgroundRobotic pancreaticoduodenectomy (RPD) has been increasingly used in the management of pancreatic ductal adenocarcinoma (PDAC). PATIENT AND

methodsWe present the case of a 65-year-old male with PDAC initially suspected to have liver metastasis. He underwent 11 cycles of gemcitabine and nab-paclitaxel, followed by diagnostic laparoscopy with liver biopsy, which revealed no malignancy. Then, surgical resection was recommended. Intraoperatively, after careful dissection of the SMV, a 5-mm segment of tumor adherence was identified on the right wall of the SMV. A stapled wedge resection was then performed. The SMV lumen appeared mildly narrowed after stapling, but no stenosis was evident and venous flow was satisfactory by inspection. This maneuver allowed medial retraction of the PV-SMV, facilitating exposure of the superior mesenteric artery and completion of resection-without vascular clamping.

resultsThe operation time was 6 h, with minimal blood loss. The patient was discharged on postoperative day 5 without complications, including venous-related events. Final pathology confirmed portal vein invasion, but an R0 resection was achieved. Among five patients who underwent PV/SMV wedge resection at our institution, no postoperative venous thrombosis or stenosis occurred.

conclusionsStapled wedge resection of the PV/SMV is feasible and safe during RPD for selected patients with minimal venous adherence. Further case accumulation and long-term evaluation are required to determine the appropriate indications, particularly with respect to safety and oncologic outcomes.
