原发性腹膜后肿瘤的手术治疗体会

目的分析总结原发性腹膜后肿瘤的手术治疗情况。方法回顾性分析28例经手术治疗的原发性腹膜后肿瘤的临床资料。结果28例均经手术治疗。良性肿瘤10例中肿瘤完全切除7例，肿瘤部分切除3例，合并脏器（大肠）切除2例。恶性肿瘤18例中，肿瘤完全切除者9例，肿瘤部分切除6例，手术探查活检3例，合并脏器（子宫、肾、脾）切除3例。其中4例因术后复发再次行手术切除。结论肿瘤浸润至大血管和多脏器是影响切除率的主要因素，而复发肿瘤仍有可能完全切除。

Experience in surgical treatment of primary retroperitoneal tumors

Objective To analyse the clinical data of cases of primary retroperitoneal tumor (PRT)admitted during the period from January 1998 to November 2008.Methods A retrospective clinical data analysis was made on the 28 cases of PRT who underment operation.Results There were 28 cases of primary retroperi-toneal tumor which were proved by operation.There were 10 cases of benign tumor,totally removal of tumor was performed in 7cases and partial in 3 cases,total resection of the tumor and other implicated organs ( intestinumcrassum ) in 2 cases.There were 18 cases of malignant tumor,totally removal of tumor was performed in 9 cases and partial in 6 cases ,surgical exploration and biopsy in 3 cases,total resection of the tumor and other implicated organs ( uterus, renal, speen ) in 3cases.Reoperation was carried out in 4 recurrent cases.Conclusions The leading factors which prevent complete resection are large vessel and/or multiple organs involvement; however,complete resection could still be expected in many recurrent cases.
