自从腹腔镜或机器人手术成为妇科医生和泌尿科医生的常见手术以来，全子宫切除术或全膀胱切除术后阴道套裂的情况一直在增加。一名 52 岁女性因肌层浸润性膀胱癌在 Rakuwakai Otowa 医院接受了腹腔镜根治性全膀胱切除术。手术后四个月，她因阴道突出一个拳头大小的肿块而紧急入院。入院时的体格检查和既往病史显示膀胱切除术后阴道套囊裂开。计算机断层扫描和磁共振成像显示肿块中没有肠内脏。我们确认肿块内容物是腹膜组织，并通过腹腔镜手术将其切除。同时，我们用股薄肌皮瓣修复了阴道套裂。在一年的随访中，没有出现阴道裂开或膀胱癌的复发。

Vaginal cuff dehiscence after total hysterectomy or total cystectomy had been increasing since laparoscopic or robotic surgery became a common surgery among gynecologists and urologists. A 52-yearold woman underwent laparoscopic radical total cystectomy for muscle invasive bladder carcinoma at Rakuwakai Otowa Hospital. She was emergently admitted with a fist-sized lump protruding from her vagina four months after surgery. Physical examination and her past history on admission disclosed vaginal cuff dehiscence after cystectomy. Computed tomographic scan and magnetic resonance imaging showed no bowel evisceration in the lump. We confirmed that the content of lump was peritoneal tissue and removed it by laparoscopic surgery. Simultaneously, we repaired the vaginal cuff dehiscence with a gracilis myocutaneous flap. There was no subsequent recurrence of vaginal dehiscence or bladder carcinoma in one-year follow-up.
