Retroperitoneal laparoscopic liposuction for large adrenal myelolipomas: a report of nine cases.

Abstract Objective: Removing relatively large adrenal myelolipomas using retroperitoneal laparoscopy is difficult and carries risk of intraoperative injury to adjacent organs and vessels. We aimed to introduce a new method of retroperitoneal laparoscopic liposuction with suction units for resection of large adrenal myelolipomas. Patients and Methods: From June 2005 to October 2011, 8 patients (nine lesions, including bilateral lesions in 1 patient) with adrenal myelolipoma more than 8 cm in maximum diameter underwent retroperitoneal laparoscopic liposuction with suction units. Patients included 3 males and 5 females with a mean age of 47 years (range, 35–62 years). Tumor resection was performed after deflation and shrinkage of tumor. The mean maximum diameter was 10.5 cm, ranging from 8 to 14 cm. Five tumors were located on the right side, two were on the left side, and one was bilateral. Adrenal computed tomography was done in each patient preoperatively. Round or oval masses were found in dense fat in t...
