目的 探讨术中超声在儿童后腹膜肿瘤切除手术中的应用价值。 方法 2016年1月至2016年11月间本院应用术中超声辅助后腹膜巨大实体肿瘤的手术切除14例,其中男性6例,女性8例,年龄最大9岁,最小6个月,平均年龄(5.96±3.13)岁。 结果 术后病理类型包括神经母细胞瘤6例,节细胞神经母细胞瘤5例,盆腔纤维瘤1例,促结缔组织增生性小圆细胞恶性肿瘤1例,复发脂肪母细胞瘤1例。14例行肿瘤完整切除术,手术时间5～12 h,术中出血量150～1000 mL,术后随访时间6～11个月,均恢复良好。术后并发乳糜腹1例,经保守治疗后治愈,无血管损伤导致脏器切除、无粘连性肠梗阻等术后并发症。 结论 术中超声能够提高手术的准确性、安全性,有助于肿瘤的完整切除。
Objective To explore the application of intraoperative ultrasonography(IOUS)during resection of pediatric retroperitoneal tumor. Methods Between January 2016 to November 2016, 14 cases of retroperitoneal tumors were operated with the aid of intraoperative ultrasonagraphy. There were 6 boys and 8 girls with an age range of 6 to 108 months. Results After surgery, pathological types included neuroblastoma(n=6), ganglioneuroblastoma(n=5), fibroma in pelvis(n=1), small round cell tumor(DSRCT, n=1)and relapsing liposarcoma(n=1). Complete total resection(CTR)was achieved in all patients. The operative duration was 5～12 hours and volume of blood transfusion 150～1000 mL. One case of abdominal chyle healed after conservative measures. During a follow-up period of 6 to 11 months, all patients recovered well without any evidence of recurrence. Conclusion Intraoperative ultrasound may enhance the surgical safety and efficacy to aid complete tumor resection.
