Introduction
Laparoscopic adrenalectomy (LA) is the standard for removal of adrenal pheochromocytomas (pheos), but laparoscopic (LAP) resection of paragangliomas (PGs) is controversial. This study analyzes our results of resection of PGs in the LAP era.
Methods
A retrospective record review of all patients who underwent resection of intra-abdominal PGs from 1998 to 2011 was performed. Pre- and postoperative clinical, radiologic, biochemical, and pathologic data for LAP resection of PGs were compared with patients who underwent LA for adrenal pheo (LA pheo; n = 62). Statistical analysis was performed and data are reported as mean ± SD.
Results
Fifteen patients had resection of PGs (6 OPEN, 9 LAP) and 62 had LA pheo. Most common PG locations were perirenal or renal hilum (n = 6) and para-aortic (n = 4). One LAP PG was converted to OPEN due to inflammation from a prior biopsy. Mean age of LAP PGs was 45.3 ± 13.2 years, and mean tumor size was 3.3 ± 2.1 cm. OPEN PGs were larger (5.1 vs. 3.3 cm), had shorter operative times (173 vs. 254 min), and longer hospitalization (5.7 vs. 2.6 days) and ICU stays (1.33 vs. 0.22 days) compared with LAP PGs (p ≤ 0.05). Compared with LA pheo, operative times for LAP PG were significantly longer (254 vs. 175 min, p = 0.001) but other outcomes were similar. Complications occurred in 5.9 % of LA pheos, 22 % of LAP PGs and 67 % of OPEN PGs.
Conclusions
Patients with paragangliomas can safely benefit from LAP resection with outcomes similar to adrenal pheos. In the absence of a need for contiguous organ resection, LAP resection of paragangliomas seems to be the preferred surgical approach.
