Our objective was to evaluate the complications and early follow-up of the tension-free vaginal tape (TVT)-SECUR, a new minimally invasive anti-incontinence operative procedure. A prospective, observational, and consecutive patient series was conducted. Perioperative and 12-month postoperative data were prospectively collected for the first 50 patients against the next consecutive 50 patients, among which TVT-SECUR specific surgical measurements were adopted (Canadian Task Force classification 2). In private hospital operative theatres, the TVT-SECUR operation was performed. Patients with urodynamically proved stress urinary incontinence were enrolled in this study after detailed informed consent was given. The TVT-SECUR, in the hammock shape to mimic the TVT-obturator placement, yet with no skin incisions, required neither bladder catheterization nor intraoperative diagnostic cystoscopy. The clinical and surgical data of 100 consecutive patients with TVT-SECUR were collected prospectively. Two patients had urinary obstructions and needed surgical tape-tension relief. One patient had a 50 mL paravesical self-remitting hematoma. At the first-month postoperative follow-up appointment, the objective therapeutic failure rate for the TVT-SECUR procedure among the 50 patients was 20.0% (10 patients). But when the tape was placed close to the urethra with no space allowed in between, the failure rate in the second patient group went down to 8.0% (4 patients); yet no further postoperative bladder outlet obstruction was diagnosed. Four (8.0%) patients in the first group had vaginal wall penetration with the inserters, requiring withdrawal, reinsertion, and vaginal wall repair. This was avoided with the second patient group by facilitating the inserters' introduction by widening the submucosal tunnel to 12 mm. Six (12.0%) other patients in the first group needed postoperative trimming of a vaginally extruded tape segment, performed in the office with satisfactory results. This problem was addressed later by making the submucosal dissection deeper to avoid intimate proximity of the tape with the vaginal mucosa. Consequently the tape protrusion rate was reduced to 8% (4 patients). Five (10.0%) patients in the first group had unintended tape removal at the time of inserter removal, necessitating the use of a second TVT-SECUR. This was addressed by meticulous detachment of the inserter before its withdrawal, after which no further unintended tape displacements were recorded. No clinical signs for bowel, bladder, or urethral injuries; intraoperative bleeding; or postoperative infections were evident. Telephone interview at the end of 12 months postoperatively was completed with 44 (88.0%) of the first patient group and 46 (92%) of the second patient group. In all, 39 (88.6%) and 43 (93.5%) of the telephone-interviewed patients of the first and second groups, respectively, reported objective urinary continence. The TVT-SECUR, a new midurethral sling, was associated with early safety and efficacy problems. These were identified and rectified, to make the TVT-SECUR a safe and effective anti-incontinence procedure. Operative complications associated with the TVT, such as bladder penetration and postoperative outlet obstruction, and TVT-obturator complications, such as postoperative thigh pain and bladder outlet obstruction, may be reduced with the TVT-SECUR. The first 100 operations' cumulative data analysis yielded some insights, including the necessity of meticulous and proper dissection before placement of the tape and the need for applying minimal extra tension to the tape. However, long-term comparative data collection will be required to draw solid conclusions regarding the appropriate position of this operative technique within the spectrum of anti-incontinence operations.
我们的目标是评估新型微创抗尿失禁手术——无张力阴道吊带术(TVT)-SECUR的并发症及早期随访情况。我们进行了一项前瞻性、观察性的连续患者系列研究。前瞻性收集了前50例患者与接下来连续50例患者的围手术期及术后12个月的数据,其中采用了TVT-SECUR特定的手术测量方法(加拿大工作组分类2级)。在私立医院手术室进行TVT-SECUR手术。经尿动力学证实为压力性尿失禁的患者在签署详细知情同意书后纳入本研究。TVT-SECUR呈吊床形状以模仿TVT-闭孔器的放置方式,但无需皮肤切口,既不需要膀胱插管也不需要术中诊断性膀胱镜检查。前瞻性收集了100例连续接受TVT-SECUR手术患者的临床和手术数据。2例患者出现尿路梗阻,需要进行手术松解吊带张力。1例患者出现50毫升膀胱旁自限性血肿。在术后第一个月的随访预约中,50例患者中TVT-SECUR手术的客观治疗失败率为20.0%(10例患者)。但当吊带放置得靠近尿道且两者之间不留间隙时,第二组患者的失败率降至8.0%(4例患者);且术后未再诊断出膀胱出口梗阻。第一组中有4例(8.0%)患者的插入器穿透阴道壁,需要拔出、重新插入并修复阴道壁。通过将黏膜下隧道加宽至12毫米以方便插入器插入,第二组患者避免了这种情况。第一组中的另外6例(12.0%)患者需要在门诊对阴道内突出的吊带段进行术后修剪,效果满意。后来通过加深黏膜下剥离以避免吊带与阴道黏膜紧密相邻解决了这个问题。因此吊带突出率降至8%(4例患者)。第一组中有5例(10.0%)患者在拔出插入器时意外移除了吊带,需要再次使用TVT-SECUR。通过在拔出插入器前仔细分离解决了这个问题,此后未再记录到意外的吊带移位。未发现肠道、膀胱或尿道损伤、术中出血或术后感染的临床迹象。术后12个月末对第一组44例(88.0%)患者和第二组46例(92%)患者进行了电话随访。总体而言,第一组和第二组接受电话随访的患者中分别有39例(88.6%)和43例(93.5%)报告实现了客观尿失禁。新型中段尿道吊带TVT-SECUR存在早期安全性和有效性问题。这些问题已被识别并纠正,以使TVT-SECUR成为一种安全有效的抗尿失禁手术。与TVT相关的手术并发症,如膀胱穿透和术后出口梗阻,以及TVT-闭孔器并发症,如术后大腿疼痛和膀胱出口梗阻,使用TVT-SECUR可能会减少。对前100例手术的累积数据分析得出了一些见解,包括在放置吊带前进行细致恰当剥离的必要性以及对吊带施加最小额外张力的必要性。然而,需要长期收集比较数据,以便就该手术技术在抗尿失禁手术范围内的合适位置得出确凿结论。
