研究目的:

盆腔器官脱垂(POP)是一种严重影响女性生活质量的常见良性疾病,手术治疗是中重度POP的主要治疗方式。常见的腹腔镜下子宫/阴道骶骨固定术(LSC)被认为是合并后盆腔缺陷患者治疗的金标准,但该术式操作难度较大,对术者手术技巧要求较高,术中可能发生严重的神经损伤、血管损伤、输尿管损伤等,且术后腰背部疼痛发生率高达50%。近年来,腹腔镜下腹壁悬吊术(LLS)被认为可作为LSC的替代术式,在德国一项长达7.5年的随访研究显示,LLS在POP治疗中的临床治愈率高,患者术后满意度超过80%,手术并发症少,复发率低,是一种治疗POP安全有效的术式。但传统的LLS采用的是多孔腹腔镜技术,需在患者腹壁作6个5-10mm穿刺孔。有研究显示,腹腔镜穿刺孔并发症的发生率随着穿刺孔大小及数量的增加而增加,如出血、感染、切口疝等,且多个手术瘢痕影响美观。我科在传统LLS基础上,率先开展单孔腹腔镜下改良微小穿刺孔-腹壁悬吊术(改良LLS),经人体天然瘢痕-脐部做2.5cm穿刺孔,其次在腹壁两侧各做一2mm微小穿刺孔牵引网片,术后患者腹部无可见瘢痕。改良LLS术式进一步减少患者手术创伤,促进愈合,同时也更易被爱美女性所接受,更符合妇科微创手术的发展理念。 本项目主要探讨改良LLS与传统LLS在盆腔脏器脱垂治疗中的疗效、手术相关并发症、术后复发率以及患者满意度等方面的对比,通过统计分析相关数据,来研究改良LLS在治疗POP中是否存在优越性,以期为临床POP的治疗提供更多选择。  

Objectives of Study:

Pelvic organ prolapse (POP) is a common benign condition that severely impacts women's quality of life. Surgical intervention is the primary treatment for moderate to severe POP. Laparoscopic sacrocolpopexy/sacrocervicopexy (LSC) is considered the gold standard for patients with concurrent posterior pelvic floor defects. However, this procedure is technically challenging and demands high surgical skill from the operator. Serious intraoperative complications such as nerve injury, vascular injury, and ureteral injury may occur, and the incidence of postoperative lower back pain is as high as 50%. In recent years, laparoscopic lateral suspension (LLS) has been proposed as an alternative to LSC. A German study with a follow-up period of up to 7.5 years showed that LLS achieves high clinical cure rates in POP treatment, with patient satisfaction exceeding 80%, fewer surgical complications, and low recurrence rates, making it a safe and effective procedure for POP. However, traditional LLS employs multiport laparoscopy, requiring six 5-10mm trocar incisions on the abdominal wall. Studies indicate that the incidence of trocar-related complications, such as bleeding, infection, and incisional hernia, increases with the size and number of trocar ports. Additionally, multiple surgical scars can affect aesthetics. Our department has pioneered a modified minimally invasive port-lateral suspension technique (modified LLS) based on traditional LLS, utilizing single-port laparoscopy. A 2.5cm incision is made at the umbilicus—a natural scar site—with an additional 2mm mini-port on each side of the abdominal wall for mesh traction, leaving no visible scars postoperatively. The modified LLS technique further reduces surgical trauma, promotes healing, and is more acceptable to cosmetically conscious women, aligning better with the concept of minimally invasive gynecological surgery. This project primarily aims to compare the efficacy, surgery-related complications, postoperative recurrence rates, and patient satisfaction between the modified LLS and traditional LLS in the treatment of pelvic organ prolapse. By statistically analyzing relevant data, we seek to investigate whether the modified LLS offers superiority in treating POP, hoping to provide more options for the clinical management of POP.

盲法:

由于手术方式的差异,本研究无法对患者和外科医生实施盲法,但对其他关键环节实施了严格的盲法以最小化偏倚。未设盲人员: 参与者和外科医生知晓治疗分配。设盲人员与措施:1、结局评估者: 进行POP-Q检查的评估者不知分组且无法接触手术记录。2、数据收集者: 负责问卷管理的研究协调员不知治疗分配。3、统计分析人员: 在数据库锁定前对分组不知情。4、影像评估者: 对影像和照片进行评估的独立评审员不知分组情况。

Blinding:

Due to the nature of the surgical intervention, complete blinding was not feasible. Participants and surgeons were necessarily aware of treatment allocation due to visible differences in incision patterns. However, we implemented several measures to minimize bias: (1) outcome assessors conducting POP-Q examinations were blinded to group assignment and had no access to surgical records; (2) questionnaire administration was performed by research coordinators blinded to treatment allocation; (3) statistical analysts remained blinded until database lock; and (4) all imaging and photographic assessments were performed by independent reviewers blinded to treatment group.
