Laparoscopic resection of a paraganglioma located on the border of the thoracic and abdominal cavities using a transabdominal‐transdiaphragmatic approach

Abstract

We treated a 64-year-old woman with high blood pressure. Catecholamine metabolite levels were elevated in the blood and urine. CT revealed a densely stained tumor on the right side of the descending aorta dorsal to the inferior vena cava. PET-CT revealed abnormal accumulation of (18) F-fluorodeoxyglucose, and (123) I-meta-iodo-benzylguanidine uptake was apparent on scintigraphy. The tumor was determined to be a paraganglioma located on the border between the thoracic and abdominal cavities, and laparoscopic tumorectomy was performed. The patient was placed in the left lateral position. The right lobe of the liver was turned over, and we cut the diaphragm to expose the front of the tumor. We resected the straight artery flowing in from the aorta and removed the tumor safely. Herein, we describe the removal of a paravertebral paraganglioma located in the border of the thoracic and abdominal cavities with a laparoscopic transabdominal-transdiaphragmatic approach.

A patient with paraganglioma undergoing laparoscopic resection: A case report

“…A PubMed search for reports on laparoscopic surgery for abdominal PGL with paraganglioma/laparoscopic revealed 12 case reports, including this case, in a 10‐year period from 2010 to 2020 (Table 1). 18‐28 The average age was 44.9 years (22‐72), and the male:female ratio was 5:7. Laparoscopic approaches consisted of the transperitoneal approach in 11 cases and transthoracoabdominal approach in 1 case.…”
