To compare the frequencies of pelvic lymphocele formation after laparoscopic and open pelvic lymph node dissection in patients with prostate cancer.
A total of 132 patients operated on with pelvic lymph node dissection (PLND) underwent CT scanning of the abdomen and pelvis at a median of 29 days postoperatively. Open pelvic lymph node dissection (OPLND) was performed in 94 patients (71%) and 38 patients (29%) were operated on using a laparoscopic technique (LPLND). The frequency and size of pelvic lymphoceles were registered. Lymphoceles with a horizontal diameter of </=4.9 cm were classified as small and those with a horizontal diameter of >/=5.0 cm were classified as large.
The overall frequency of lymphoceles was 54%. The frequencies in the OPLND and LPLND groups were 61% and 37%, respectively. A total of 27% of the OPLND patients had large lymphoceles, compared to 8% of the LPLND patients. Three patients (2.3%), all in the OPLND group, had clinically significant lymphoceles.
Although the overall frequency of lymphocele formation was high, clinically significant lymphoceles were scarce. LPLND was associated with a statistically significant lower frequency of lymphocele formation compared to OPLND.
比较前列腺癌患者腹腔镜盆腔淋巴结清扫术和开放盆腔淋巴结清扫术后盆腔淋巴囊肿形成的频率。
共有132例行盆腔淋巴结清扫术（PLND）的患者在术后中位时间29天接受了腹部和盆腔CT扫描。94例患者（71%）接受了开放盆腔淋巴结清扫术（OPLND），38例患者（29%）采用腹腔镜技术（LPLND）进行手术。记录盆腔淋巴囊肿的频率和大小。水平直径≤4.9 cm的淋巴囊肿分类为小囊肿，水平直径≥5.0 cm的淋巴囊肿分类为大囊肿。
淋巴囊肿的总体发生率为54%。OPLND组和LPLND组的发生率分别为61%和37%。OPLND组共有27%的患者有大淋巴囊肿，而LPLND组为8%。3例患者（2.3%），均在OPLND组，有具有临床意义的淋巴囊肿。
虽然淋巴囊肿形成的总体发生率较高，但具有临床意义的淋巴囊肿很少见。与OPLND相比，LPLND在统计学上与较低的淋巴囊肿形成频率相关。
