Lateral retroperitoneal approach for the treatment of a recumbent silkworm-like paravertebral schwannoma in the lumbar spine: a case report.

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
Objective: This case report describes the surgical management of a recumbent silkworm-like paravertebral schwannoma in the lumbar spine resected via the lateral retroperitoneal approach. Methods: A lumbar paravertebral schwannoma resembling a "recumbent silkworm" was excised using the lateral retroperitoneal approach. Intraoperative measures included electrophysiological monitoring and insertion of a ureteral D-J stent to protect critical surrounding anatomical structures. Complete tumor resection was achieved without intraoperative complications. Follow-up demonstrated no tumor recurrence or postoperative complications. Results: The duration of surgery was 310 min, with an estimated blood loss of 50mL. The tumor resection rate was 100%. The patient was discharged 11 days after hospitalization. Postoperative histopathological examination confirmed the diagnosis of schwannoma. There were no postoperative complications. The patient ADL (Activities of Daily Living score did not decline compared with the preoperative levels. After one year of follow-up, no signs of tumor recurrence were observed. Conclusion: Paravertebral tumors located in the anterior and lateral aspects of the lumbar spine pose significant surgical challenges because of their complex position and morphology. Complete excision of such tumors via the lateral retroperitoneal approach is an optimal treatment strategy.
