Objective To summarize the experience in diagnosis and treatment of primary retroperitoneal tumor (PRT). Methods Clinical data of 69 patients with PRT from June 1998 to June 2008 were analyzed retrospectively. Results Bellyache, abdominal distention, and abdominal mass were common symptoms in the patients with PRT. Ultrasound, CT, and MRI examination were effective. The major histopathological classification was soft tissue tumor, germinoma, lymphatic hematopoietic system tumors, and other rare tumors. Complete resection of tumors was performed in 42 cases, combined organs resection in 10 cases, partial resection of tumors in 11 cases, and only biopsy in 6 cases. There were 10 cases of intraoperative vessel and organ injury, which were treated by repair or vessels suturing and combined organ resection. Postoperative complications occurred in 8 cases, which were cured by conservative treatment. One patient died of hemorrhage acute stress ulcer combined multiple organ failure. The survival rates of 1, 3, and 5 years in patients underwent complete resection of tumors were 71%, 64%, and 46%, respectively. Of 11 patients underwent partial resection of tumors, 8 cases died within one year, and 3 cases died within 3 years after operation. All malignant tumor patients treated by biopsy died within one year after operation.Conclusion Synthetically using imaging examination may diagnose definitely, and to resect tumors as much as possible will improve patients’ survival.
ObjectiveTo evaluate the safety and feasibility of laparoscopic resection of primary retroperitoneal tumors. MethodClinical data of 52 patients diagnosed as primary retroperitoneal tumor who underwent laparoscopic resection in Peking University Third Hospital from January 2006 to December 2015 were retrospectively collected and analyzed. ResultsFifty two patients were included in the review. In 21 patients (40.3%), tumors were adjacent to major vessels (such as inferior vena cava, superior mesenteric vein, and the splenic vessel), tumors of 31 patients (59.7%) were away from major vessles. Two operations (3.8%) were converted to hand-assistant and 2 operations (3.8%) were converted to laparotomy due to tight adherence to major vessels. The mean value of operative time was 171.4-minute (60-520 minutes) and the mean value of length of incision was 2.8 cm (1-15 cm), the mean value of estimated blood loss was 86.4 mL (10-1 150 mL), 2 patients needed blood transfusion. The mean value of time of returning to diets was 1.5-day (1-5 days) and the mean value of length of postoperative hospital stay was 4.9-day (1-16 days). There was no major postoperative complications or death. Follow up was available for 47 patients at a median time of 62.0-month (4-120 months). Three patients with retroperitoneal liposarcomas experienced recurrence at 31, 34, and 48 months after operation, 1 patient with mucinous peripheral neurilemmoma experience recurrence at 69 months after operation, all of which underwent further resection, with others experiencing no recurrence or metastasis. Three patients died in reason of other diseases. ConclusionsLaparoscopic surgery can be performed safely in the treatment of primary retroperitoneal tumors, even when a tumor adjacent to major vascular structures.
