世界首例单孔腹腔镜根治性膀胱切除、全去带乙状结肠原位新膀胱术

目的 报告世界首例单孔腹腔镜(LESS)根治性膀胱切除术,并采用全去带乙状结肠构建原位膀胱.方法 患者为74岁男性,因血尿2月人院,活检病理确诊为膀胱癌.行LESS根治性膀胱切除术,于下腹正中取3.5 cm纵形切口,置入单孔多通道套管(R-port)建立手术入路.手术过程包括双侧盆腔淋巴结清扫.根治性膀胱切除术完成后,开放构建全去带乙状结肠原位新膀胱.结果 手术总时间9.5 h,LESS部分5.5h.术中采用传统腹腔镜器械,没有增加其它通道,最终病理结果为尿路上皮癌.术中失血约600ml,输注红细胞400ml.清扫的盆腔淋巴结均为阴性.尿道及输尿管切缘未见肿瘤侵犯.围手术期未发生水电平衡紊乱及酸碱失衡.术后3月复查,未见肿瘤复发和远处转移,新膀胱容量约280ml.残余尿10ml,最大尿流率11.1 ml/s.结论 尽管LESs手术有着更长的学习曲线,但有望成为治疗浸润性膀胱肿瘤的更加微创更美观的手术方法.
