We have been applying endoscope-assisted minilaparotomy (endoscopic minilaparotomy) to retroperitoneal operations with favorable outcomes. Here, endoscopic minilaparotomy through a single flank incision (4-7 cm) was performed in three cases of incidentally discovered retroperitoneal Schwannoma. Resection of the tumor was successfully completed. The postoperative course was uneventful. Wound pai...

Lipomas can occur almost anywhere in the body, but retroperitoneal lipomas are extremely rare. They are slowly growing benign tumors and can attain an enormous size due to silent course of the disease. Total excision of the mass is the treatment of choice and is curative for benign retroperitoneal lipomas. We treated an 11-month-old female patient with giant retroperitoneal lipomas by surgical ...

BACKGROUND Leiomyomas are benign tumors observed mainly in adult women. The retroperitoneum is a rare location for leiomyomas; almost 100 cases have been reported. Because retroperitoneal leiomyomas are paucisymptomatic and the tumor size at diagnosis is relatively large, surgical management is challenging. Regular follow-up is required because recurrence and malignant sarcomatous transformatio...

Patients with giant retroperitoneal liposarcomas are considered at great risks of perioperative complications and require meticulous anaesthetic management. There have been few reports about anaesthetic management of giant retroperitoneal liposarcoma. We present the case of a 66-year-old patient who suffered from a giant retroperitoneal liposarcoma (diameter 45 cm and weigh 4.5 kg), needing a r...

Dear Sir, We read the article titled ‘Modified Retroperitoneal Access for Percutaneous Intervention after Pancreaticoduodenectomy’ by Uei Pua et al. (1) published in Korean J Radiol (2013;14:446-450) with a great interest. Therein, authors reported two cases which needed retroperitoneal access. They approached the retroperitoneal space by using anterior pararenal trajectory. This technique is u...

A case of retroperitoneal leiomyosarcoma (LMS) in a 38-year-old woman who had a tumor in the retroperitoneum with severe hypertension and hypokalemia is presented. Further investigation revealed an elevated serum aldosterone and norepinephrine level. After tumorectomy, the levels of serum aldosterone and norepinephrine successfully normalized; hypertension and hypokalemia were also cured. The t...

Retroperitoneal sarcomas are rare tumors associated with a high rate of recurrence and very bad prognosis. Their only efficient treatment is a negative- margin surgical resection that is extremely difficult to achieve. Retroperitoneal metastases from extremity sarcomas are considered unusual. In literature, such a metastatic pattern is described extremely rarely. In this paper we report a case ...
