A patient with paraganglioma undergoing laparoscopic resection: A case report

Hisamichi Yoshii et al. Clin Case Rep. .

Abstract

Paraganglioma is a very rare extraadrenal nonepithelial tumor. The number of cases of laparoscopic surgery in Paraganglioma is small and controversial. This study encountered a case of successful transperitoneal laparoscopic surgery for a 56-mm paraganglioma in a 53-year-old female. Moreover, previous reports on laparoscopic surgery for paraganglioma are reviewed.

Keywords: general surgery; neurosurgery; oncology.

FIGURE 4
Endoscopic ultrasound image. A 47.3 × 31.3‐mm hypoechoic tumor at the posterior wall of the middle part of the gastric corpus. It is suspected to be derived from the muscular layer of the fourth layer of the gastric wall (red arrow)

Surgical findings. The pancreas was tunneled and lifted; the tumor and the retroperitoneum were then exfoliated

Surgical findings. Feeding vessels flow from the left gastric artery toward the tumor (red arrow)
FIGURE 7
FIGURE 7
Macroscopic findings. A round tumor with capsule with a clear boundary was observed, and no necrosis existed on the cut surface. Moreover, yellow consolidation was observed
