INTRODUCTION
Robot-assisted radical prostatectomy (RARP) has become a popular surgical approach for localized prostate cancer due to its favorable oncological and functional outcomes, as well as lower morbidity. In cases of intermediate- and high-risk prostate cancer, bilateral pelvic lymphadenectomy (PLND) is recommended as an adjunct to RARP (1-3). Despite its benefits, PLND can lead to surgical complications, with postoperative lymphocele formation being the most common. Most postoperative lymphoceles are clinically insignificant with variable incidence, reaching up to 60% of cases 4. However, a small percentage of patients 2-8% may experience symptomatic lymphoceles (SL), which can cause significant morbidity (4, 5).
SURGICAL TECHNIQUE
We perform our RARP technique with our standard approach in all patients (6). After vesicourethral anastomosis a modified PF created to prevent symptomatic lymphocele. We start by suturing the peritoneal fold on the right side, medially to the vas deferens, followed by a similar stitch on the left side to approximate the edges in the midline. A running suture bunches the bladder peritoneum from both sides, passing through the pubic bone periosteum to secure it in place (7). This approach keeps the lateral pelvic gutters open for lymphatic drainage, while allowing fluid drainage from the true pelvis into the abdomen. A pelvic ultrasound was done for all patients at 6 weeks post operative, and additional clinical follow-up was carried out at 3 months following surgery.
CONSIDERATIONS
We have demonstrated a modified technique of peritoneal flap (PBFB) with an initial decrease in postoperative symptomatic lymphoceles, the technique is feasible, safe, does not add significant morbidity, and does not require a learning curve.
简介
机器人辅助根治性前列腺切除术(RARP)由于其良好的肿瘤学和功能结果以及较低的发病率,已成为治疗局限性前列腺癌的一种流行手术方法。对于中高危前列腺癌患者,建议将双侧盆腔淋巴结清扫术(PLND)作为 RARP 的辅助手段(1-3)。尽管 PLND 有其益处,但它可能导致手术并发症,术后淋巴囊肿形成是最常见的。大多数术后淋巴囊肿具有临床意义不显著,发生率可高达 60%(4)。然而,少数患者(2-8%)可能会出现有症状的淋巴囊肿(SL),这可能导致严重的发病率(4,5)。
手术技术
我们在所有患者中都采用标准方法进行 RARP 技术(6)。在完成膀胱输尿管吻合后,我们会创建一个改良的 PF 以预防有症状的淋巴囊肿。我们首先缝合右侧腹膜褶皱,靠近输精管,然后在左侧进行类似的缝合,使边缘在中线附近靠拢。连续缝合将膀胱腹膜从两侧束紧,穿过耻骨骨膜以将其固定在适当位置(7)。这种方法使外侧骨盆槽保持开放以进行淋巴引流,同时允许从真正骨盆向腹部引流液体。所有患者在术后 6 周进行盆腔超声检查,并在手术后 3 个月进行额外的临床随访。
注意事项
我们已经证明了一种改良的腹膜瓣(PBFB)技术,该技术可初始减少术后有症状的淋巴囊肿,该技术可行、安全、不会增加显著的发病率,并且不需要学习曲线。
