“…Catecholamine release into the bloodstream may be triggered by any stressful situation. Currently laparoscopy, by both trans-and retroperitoneal access [6][7][8], is the surgical treatment of choice. This is feasible only in cases where paragangliomas are located: along with sympathetic ganglions inferiorly to the renal vessels, in proximity to the renal hilum, and in some cases originating from the organ of Zuckerkandl.…”

Introduction: Extraperitoneal, abdominal paragangliomas most commonly originate from the sympathetic nervous system. Typical features include catecholamine overproduction and the potential for malignancy. Lesions are usually located paravertebrally, but when growing in a more expansive manner they may also appear between the inferior vena cava and aorta. In the authors' opinion this site excludes laparoscopic tumourectomy. Material and methods: Twenty-eight patients were selected for surgical management of abdominal paragangliomas in the past eight years at our endocrine surgical centre. This group consisted of 21 (75%) women and seven (25%) men, aged 14 to 84 years (mean 47.9). In 13 (46.4%) cases paroxysmal hypertension was observed. Type 2 diabetes was noted in another 10 (35.7%) patients, and Takotsubo acute coronary syndrome in two (7.1%). Patients were preoperatively qualified for either open surgery or laparoscopic tumourectomy based on visualisation and location of the tumours in imaging studies. Results: All patients were successfully operated. Eleven (39.3%) patients qualified for laparoscopy, while the remaining 17 (60.7%) were treated with an open surgical approach due to difficult access to the lesion. The mean operative time was 130 minutes for laparoscopy and 120 minutes for laparotomy (p = 0.2). There were no local or general complications after either type of procedure. Conclusions: The use of laparoscopic access is practically excluded in the treatment of paragangliomas located between the inferior vena cava and aorta, especially at the level of the renal vessels and extending superiorly to the diaphragm.

“…With respect to the surgical approach, surgeons should have a thorough understanding of the anatomical structures of adjacent organs and accompanying vessels. 25 , 26 Considering the heterogeneous appearance on imaging and risk of recurrence, en bloc radical excision of the mass is usually recommended. 27 Although complete excision of a giant neoplasm is challenging and has a risk of complications, it is vital to prevent tumor recurrence or malignant transformation after complete tumor resection by laparoscopic or open surgery.…”

Neurilemmoma, also known as schwannoma or neurinoma, is a tumor that originates from neural sheath Schwann cells. Giant neurilemmomas derived from the retroperitoneum have rarely been reported. We herein describe a woman with a giant retroperitoneal neurilemmoma that was initially incorrectly diagnosed as an inflammatory abdominal mass. The tumor extended from the patient’s hypogastrium to her pelvic cavity and measured 20 × 15 × 10 cm. The tumor was excised via laparotomy and diagnosed as a retroperitoneal neurilemmoma through histological and immunohistochemical examination. Although rare, particularly in the giant form, neurilemmoma should be considered as an important differential diagnosis in patients with a retroperitoneal tumor or inflammatory abdominal mass. Complete excision should be considered for the potential cure of giant retroperitoneal neurilemmomas.

“…However, several reports have described the safety of laparoscopic surgery for retroperitoneal tumors, indicating that the laparoscopic approach is feasible in experienced hands. In our hospital, laparoscopic surgery is usually performed by an operator who is proficient in retroperitoneal tumor resection.…”

Introduction Paragangliomas have a rich blood flow and are located around large vessels; thus, resection is often difficult. We herein report a case of a paraganglioma that was located immediately behind the inferior vena cava and bilateral renal veins and successfully resected by laparoscopic surgery. Case presentation A 72‐year‐old man was incidentally diagnosed with a 7‐cm retroperitoneal mass immediately behind the inferior vena cava and bilateral renal veins by computed tomography. The mass was diagnosed as a retroperitoneal paraganglioma. The patient underwent laparoscopic surgery in the left lateral decubitus position. The tumor was dissected completely with no complications. Conclusion Resection of retroperitoneal paragangliomas is often a surgical challenge. The feasibility of the laparoscopic approach to such paragangliomas was demonstrated in the present case.
