原发性腹膜后肿瘤的手术治疗体会

Experience in surgical treatment of primary retroperitoneal tumors

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。

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 retroperitoneal tumor which were proved by operation.There were 10 cases of benign tumor,totally removal 0ftumor was performed in 7cases and partial in 3 cases,total resection of the tumor and other implicated organs （ intestinum crassum ） 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.
