原发性盆部腹膜外肿瘤84例的外科治疗

目的　探讨原发性盆部腹膜外肿瘤的外科治疗经验及技巧。方法　回顾性分析原发性盆部腹膜外肿瘤 84例临床资料 ,其中良性 33例 ,低度恶性 33例 ,高度恶性 18例。术前 6例行血管造影并髂内动脉栓塞。经腹、经骶及位腹骶入路切除者分别 5 8、16、10例。结果　 84例均进行手术治疗 ,其中 1例半年内 4次手术切除肿瘤。 6 8例达肿瘤全部切除 (81% ) ,其中良性肿瘤切除率为 94 %(31/33)。行盆腔脏器联合切除者 35例 ,其中全盆腔脏器切除 2例、前盆腔脏器切除 2例。行髂总、髂外血管切除共 5例 ,均行人造血管移植 ;髂内动脉结扎 10例。术中出血最多 15 0 0 0ml,平均 2 385ml。切除肿瘤最大 30cm× 30cm× 2 5cm ,无手术死亡 ,并发症发生率 7% (6 /84 )。术后 37例获随访 ,平均随访 5 4个月 ,仅 1例死亡 ,2 1例复发者再行 2 2例次手术 ,其中 1例术后多次复发共行 7次手术存活12年。结论　联合切口及联合脏器切除 ,必要时行髂血管移植 ,分次切除及复发后再切除 ,是原发性盆部腹膜外肿瘤治疗的有效手段

Surgery for extraperitoneal pelvic neoplasms

OBJECTIVE: To evaluate the methods of surgery for extraperitoneal pelvic neoplasms. METHODS: Clinical data related to surgery of 84 cases of extraperitoneal pelvic neoplasms were extracted and retrospectively analyzed. RESULTS: All 84 patients underwent operations, including one of them who received 4 operations within 6 months for resection of a single tumor. 58 abdominal, 16 buttock and 10 combined incisions were made in the series. Pelvic organs and structures were co-resected in 35 cases, including total pelvic exenteration in 2 cases and anterior pelvic exenteration in 2 cases. Common and/or external iliac vessels were resected and transplantations of artificial vessel were carried in 5 cases. Internal iliac arteries were ligated in 10 cases. The mean blood lose was 2 385 ml in our series and the largest was 15 000 ml. The complete resection rate of tumor was 81% for 84 operations and the largest resected tumor was 30 cm x 30 cm x 25 cm. There was no hospitalized death, and postoperative complication rate was 7% (6/84) in our series. Only 1 death were seen during the mean period of postoperative follow-up of 54 months, 22 operations were carried for 21 cases of recurrence, including 7 operations for 7 recurrences in a case within 12 years. CONCLUSIONS: Making adequate abdominal or/and buttock incisions, exenterations of involved pelvic organs and structures, total pelvic exenteration if necessary, appropriate management of iliac vessels, planned re-operation for one tumor, and re-operation for recurrences are important methods for the treatment of extraperitoneal pelvic neoplasms.
