An unexpected retroperitoneal paraganglioma with hypertensive crisis during surgical resection: a case report and literature review.

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
Retroperitoneal paraganglioma is an extremely rare tumor. Its atypical clinical presentations often lead to missed and misdiagnosis. Here, we report a 60-year-old male with unexplained weight loss and a medical history of hypertension and diabetes. Preoperative evaluations showed a left lower abdominal mass, considered as a malignant gastrointestinal stromal tumor or a leiomyosarcoma. During the laparoscopic resection of tumor, his blood pressure fluctuated significantly, especially with the tumor manipulation that caused hypertensive crisis. Phentolamine infusion was given to control the blood pressure, and the tumor was removed under the open abdominal surgery. Further laboratory tests on catecholamine levels and postoperative histopathology confirmed the diagnosis of retroperitoneal paraganglioma. Follow-up showed good recovery with no complications. Paraganglioma should be considered when an unknown mass with severe blood pressure fluctuations is encountered during surgery. Careful preoperative preparations and close intraoperative monitoring should be applied in patients with suspected paraganglioma.
