“…Of all retroperitoneal tumors, benign tumors account for ~40% ( 2 , 10 ). Benign retroperitoneal tumors have a wide range with regard to age of onset, with the lesions typically growing slowly and exhibiting no symptoms at the early stages ( 9 , 11 – 13 ). Patients frequently seek treatment due to experiencing chronic abdominal pain and bloating, resulting from compression of the surrounding tissues by larger tumors ( 9 , 14 ).…”

Surgical treatment of a retroperitoneal benign tumor surrounding important blood vessels by fractionated resection: A case report and review of the literature

Retroperitoneal tumors are lesions with diverse pathological subtypes that originate from the retroperitoneal space; ~40% of these tumors are benign. Due to such lesions often surrounding and associating with vital abdominal blood vessels, a complete surgical resection is difficult. The current study presents a novel surgical approach, known as fractionation, through which a benign retroperitoneal tumor surrounding important abdominal blood vessels was completely resected. A 21-year-old man was admitted to The First Affiliated Hospital of Chongqing Medical University (Chongqing, China), presenting with a ~7.5×7.2-cm tumor that was located in the retroperitoneal pancreatic head region and the first hepatic hilum. The tumor completely surrounded the celiac axis and the splenic, common hepatic and superior mesenteric arteries, and was closely associated with the abdominal aorta and the portal, splenic, superior mesenteric and left renal veins. A pre-operative computed tomography scan and intraoperative frozen biopsy indicated that the lesion was a benign tumor. A fractionation approach was subsequently adopted, with fractionation of the lesion being performed according to the location of the tumor itself and the direction of the surrounding abdominal blood vessels. In this manner, a complete tumor resection was conducted. Post-operative pathological examination confirmed the diagnosis of a retroperitoneal ganglioneuroma. The patient was followed up for a year and a half, with no evidence of tumor recurrence. In the present case, a fractionation approach for the complete resection of the retroperitoneal benign tumor achieved a positive outcome and demonstrated the feasibility of the technique.

“…Although retroperitoneal tumors have traditionally been excised using the standard open technique , we chose the laparoscopic approach because of the advantages it offers. As the femoral nerve, which is buried deep within the body, can be readily distinguished from its surrounding tissues, the laparoscopic approach is useful for removing retroperitoneal tumors.…”

We report on a 45-year-old man who presented with pain in the left leg, which he had had for 2 months. A contrast-enhanced CT scan displayed a 25-mm tumor in the lateral side of the left psoas muscle. For this suspected retroperitoneal tumor, we performed laparoscopic resection of the tumor, which was encapsulated by the funicular femoral nerve, using surgical scissors rather than a surgical energy device and preserved the normal fascicles wherever possible. Pathological examination indicated a benign ancient schwannoma arising from the femoral nerve. The patient was able to return to his job 3 weeks after surgery, and he has shown no evidence of recurrence. This was thought to be because of the use of surgical scissors, rather than a surgical energy device, combined with visual magnification. Therefore, the laparoscopic approach is an effective and minimally invasive option for the resection of femoral nerve schwannoma.

“…Retroperitoneal tumors have traditionally been excised using a standard open technique: even malignant tumors with large vessel invasion can sometimes be removed completely. 1 However, fewer than ten cases of laparoscopic excision of retroperitoneal neural tumors such as schwannoma and neurofi broma have been reported in the world literature to date. [2][3][4][5][6][7] Histopathologic examination after laparotomy is often necessary to make a fi nal diagnosis because the lack of imaging features of retroperitoneal tumors makes preoperative diagnosis diffi cult.…”

Retroperitoneal neural tumors are rarely excised laparoscopically, with fewer than ten cases reported in the literature. Between February 2005 and December 2007, we performed successful planned laparoscopic excision of retroperitoneal tumors using the four-trocar technique in three patients. All three patients were women, with a mean age of 40.7 years. The mean tumor size was 4.8 cm. The mean operative time was 126 min and the mean blood loss 14.3 ml. The postoperative pathological diagnosis was schwannoma in one patient and ganglioneuromas in two. There was no morbidity or mortality. Although difficult to diagnose preoperatively, neural tumors in the retroperitoneal space are most often benign, with a good prognosis. Laparoscopic surgical techniques for retroperitoneal tumors are safe, and their use is encouraged when an appropriate diagnosis is made, after exclusion of malignant subtypes.
