Retroperitoneal Laparoscopic Surgery In The Treatment Of Primary Retroperitoneal Tumor

Objective: To investigate the feasibility and operating skills of retroperitoneallaparoscopic(retro-laparoscopic) resection of primary retroperitoneal tumor.Methods: This research retrospectively analyzed15primary retroperitonealtumor patients received retro-laparoscopic resection in surgical department ofUrology of the First Hospital of Jilin University during January2008to January2014.All patients performed preoperative imaging tests;15patients took preoperativeabdominal ultrasound examination;12patients took computer tomography (CT);5patients took magnetic resonance imaging (MRI). The average tumor size was5.8cm(2.3cm~8.1cm). The PRT was located in right adrenal area (n=3), left adrenal (n=2), beside spine (n=1), right renal under (n=2), psoas major muscle ahead (n=2),beside postcava (n=3), beside aorta (n=2) respectively. Retro-laparoscopicresection was performed.Results: The operation was accomplished successfully in all cases without anyadjacent organ or vessel injury. The average operative time was115.6min. Theaverage blood loss was155.8ml, and average postoperative hospital stay was5.8days.The pathologic diagnosis included four schwannoma cases, three ganglioneuromacases; two retroperitoneal cyst cases; one paraganglioma case; two lipoma cases; onemature teratoma case; one serous cystadenoma case and one liposarcoma case. Therehas been no tumor recurrence following up for3-32months.Conclusion: Due to the absence of specific symptoms, PRT often grows verylarge and adheres to adjacent viscera or major vessels before diagnosis; PRT is bestevaluated with preoperative imaging tests, such as ultrasound, CT or MRI. Even if thetumor is large and adheres to adjacent viscera or major vessels, retro-laparoscopicresection is a minimally invasive, safe and effective option with preoperative imagingstudies, retroperitoneal approach, and skilled retro-laparoscopic techniques.
