OBJECTIVE To review the presentation of unicornuate uterus with a functional noncommunicating rudimentary uterine horn and a laparoscopic method of management, highlighting laparoscopic surgical techniques. DESIGN A video review of unicornuate uterus with a functional noncommunicating rudimentary uterine horn and a laparoscopic approach to treatment in a 13-year-old pubertal female with severe menstrual pain. SETTING Tertiary care facility. PATIENT(S) A 13-year-old G0 was referred to the clinic for severe cyclic right lower quadrant pain during menses. Transvaginal ultrasonography revealed a left unicornuate uterus with a right-sided noncommunicating rudimentary horn measuring 4.8 × 4.7 × 4.6 cm, containing blood consistent with hematometra. Her kidneys were bilaterally present and normal by ultrasonography. INTERVENTION(S) Because of the patient's worsening pain and the presence of hematometra, we proceeded with diagnostic laparoscopy and removal of the rudimentary uterine horn. The entire procedure was performed laparoscopically, with an estimated total blood loss of 20 mL. Included are tips for laparoscopic resection and suturing. MAIN OUTCOME MEASURE(S) Pathologic features and postoperative course. RESULTS The patient's pathologic features were benign, and her severe menstrual pain was resolved. She had no complications or readmissions. CONCLUSION(S) In patients with severe menstrual pain from outflow obstruction from a noncommunicating rudimentary uterine horn with functional endometrium, laparoscopic resection can be a safe and effective method of treatment.

腹腔镜切除功能性、非交通性子宫角，接近功能性半子宫

目的 回顾具有功能性非交通性残角的单角子宫和腹腔镜治疗方法，重点介绍腹腔镜手术技术。设计 具有功能性非通信性原始子宫角的单角子宫和腹腔镜治疗一名患有严重月经痛的 13 岁青春期女性的视频回顾。设置三级护理机构。患者 一名 13 岁的 G0 因月经期间严重的周期性右下腹痛被转诊至诊所。经阴道超声检查显示左侧单角子宫，右侧有一个不连通的残角，大小为 4.8 × 4.7 × 4.6 cm，含有与血迹一致的血液。她的肾脏双侧存在并且超声检查正常。干预（S） 由于患者的疼痛加重和血迹的存在，我们进行了诊断性腹腔镜检查并切除了原始子宫角。整个过程在腹腔镜下进行，估计总失血量为 20 mL。包括腹腔镜切除和缝合技巧。主要结果测量(S) 病理特征和术后病程。结果患者病理为良性，重度经痛消失。她没有并发症或再入院。结论(S) 对于因功能性子宫内膜未连通的原始子宫角流出道梗阻而导致严重月经痛的患者，腹腔镜切除术是一种安全有效的治疗方法。我们进行了诊断性腹腔镜检查并切除了原始子宫角。整个过程在腹腔镜下进行，估计总失血量为 20 mL。包括腹腔镜切除和缝合技巧。主要结果测量(S) 病理特征和术后病程。结果患者病理为良性，重度经痛消失。她没有并发症或再入院。结论(S) 对于因功能性子宫内膜未连通的原始子宫角流出道梗阻而导致严重月经痛的患者，腹腔镜切除术是一种安全有效的治疗方法。我们进行了诊断性腹腔镜检查并切除了原始子宫角。整个过程在腹腔镜下进行，估计总失血量为 20 mL。包括腹腔镜切除和缝合技巧。主要结果测量(S) 病理特征和术后病程。结果患者病理为良性，重度经痛消失。她没有并发症或再入院。结论(S) 对于因功能性子宫内膜未连通的原始子宫角流出道梗阻而导致严重月经痛的患者，腹腔镜切除术是一种安全有效的治疗方法。包括腹腔镜切除和缝合技巧。主要结果测量(S) 病理特征和术后病程。结果患者病理为良性，重度经痛消失。她没有并发症或再入院。结论(S) 对于因功能性子宫内膜未连通的原始子宫角流出道梗阻而导致严重月经痛的患者，腹腔镜切除术是一种安全有效的治疗方法。包括腹腔镜切除和缝合技巧。主要结果测量(S) 病理特征和术后病程。结果患者病理为良性，重度经痛消失。她没有并发症或再入院。结论(S) 对于因功能性子宫内膜未连通的原始子宫角流出道梗阻而导致严重月经痛的患者，腹腔镜切除术是一种安全有效的治疗方法。
