Laparoscopic nerve-sparing radical parametrectomy for occult early-stage invasive cervical cancer after simple hysterectomy.

Objective To investigate the feasibility and surgical outcomes of laparoscopic nerve-sparing radical parametrectomy (LNSRP) and lymphadenectomy for treatment of occult early-stage invasive cervical cancer after simple hysterectomy. Methods From 2006 to 2010, 28 patients who were discovered to have occult early-stage invasive cervical cancer after a simple hysterectomy underwent LNSRP, upper vaginal resection, and pelvic lymphadenectomy. A retrospective analysis of these cases was performed. Results All patients underwent successful LNSRP. There was no conversion to laparotomy. The mean ± SD operation time was 173.30 ± 56.20 minutes. The mean ± SD estimated blood loss was 230.00 ± 109.55 mL. Two intraoperative complications were recorded. The median number of extracted pelvic and para-aortic lymph nodes was 23 (range, 12–36) and 7 (range, 3–15), respectively. The mean ± SD time before Foley catheter removal was 5.6 ± 2.74 days (range, 3–14 days ), and bladder voiding function recovery to grade 0 to grade 1 was observed in 26 patients (92.9%). Of the 28 patients, 3 patients received further adjuvant therapy. The median follow-up period was 38 (range, 4–62) months for all patients. No recurrence case was found in this series. Conclusion Laparoscopic nerve-sparing radical parametrectomy is a therapeutic option for occult early-stage invasive cervical cancer discovered after hysterectomy. Nerve-sparing radical surgery in indicated patients may lead to optimal preservation of bladder function.
