目的:探讨宫颈癌盆腔淋巴结清除术中开放盆腹膜对盆腔淋巴囊肿形成的影响。方法:以盆腔淋巴结清除术中开放盆腹膜者设为研究组(30例),盆腔淋巴结清除术中缝合盆腹膜者设为对照组(30例),对比两组术后盆腔淋巴囊肿发病率的差异。结果:研究组的术后盆腔淋巴囊肿阳性率为10.00%,对照组为33.33%,P值<0.01。结论:术中缝合盆腹膜是术后盆腔淋巴囊肿形成的原因之一。术中开放盆腹膜能显著减少术后盆腔淋巴囊肿的形成。 Objective: To investigate the effect of open pelvic peritoneum on pelvic lymphocyst formation in pelvic lymphadenectomy of cervical cancer. Methods: Pelvic lymphadenectomy was performed in 30 patients with pelvic peritoneum. Pelvic lymphadenectomy was performed in control group (30 cases). The incidence of pelvic lymphatic cyst in both groups was compared difference. Results: The positive rate of postoperative pelvic lymphocyst was 10.00% in the study group and 33.33% in the control group, P <0.01. Conclusion: Intraoperative suturing pelvic peritoneum is one of the causes of postoperative pelvic lymphatic cyst formation. Intraoperative open pelvic peritoneum can significantly reduce postoperative pelvic lymphatic cyst formation.
