BACKGROUND: Pelvic lymphoceles are the most common complications after pelvic lymphadenectomy. Microsurgical procedures have attracted attention as an alternative treatment for lymphoceles. Here, we report six cases of refractory lymphoceles that were successfully treated using lymphovenous anastomosis (LVA).
METHODS: Six patients underwent surgery for gynecological cancers and developed pelvic lymphoceles, which did not respond to conventional treatment. We mainly performed LVA on the ipsilateral lower limbs, although some procedures were also performed on the contralateral limbs. The change in the lymphocele volume after LVA was examined using computed tomography and compared using the Wilcoxon test.
RESULTS: Five of the six refractory lymphocele cases were successfully treated using LVA, and the remaining case exhibited an 87% reduction in lymphocele volume. The average numbers of anastomoses were 6.7 on the ipsilateral side and 2.8 on the contralateral side (the median numbers: 6 [range: 5-9] vs. 3 [range: 1-4], P = 0.034). The average lymphocele volume decreased significantly from 414.0 mL preoperatively to 8.0 mL postoperatively (the median lymphocele volume: 255.8 [range: 61.5-1,329.2] vs. 0 [range: 0-47.7], P = 0.0313).
CONCLUSION: We found that microsurgical treatment was potentially effective for lymphoceles that did not respond to conventional treatment.
