Paraaortic lymph node metastasis is an important prognostic factor in gynecologic malignancy. However, paraaortic lymph node dissection (PAND) is not done routinely in Japan because of the difficulty of the procedure and the high incidence of complications. We performed PAND in 217 patients in a 7-year period. In the present study, we focused on the occurrence of postoperative ileus in patients who underwent PAND.


Two hundred and seventeen patients with malignant gynecologic tumors were operated on at our hospital between January 1995 and August 2001. All patients underwent PAND and pelvic lymph node dissection (114 patients had a radical hysterectomy; 103 patients had a simple hysterectomy). We evaluated postoperative ileus in three categories of severity.


The average operation time and blood loss in the patients with radical and simple hysterectomies with PAND were 317 min and 1158 g, and 246 min and 820 g, respectively. The incidence of postoperative ileus was 12.9% (28/217). Although there were no significant differences in the occurrence of ileus between patients with the radical and simple hysterectomies (10.5% vs 15.5%), the incidence of ileus in patients with radical hysterectomy with PAND was significantly higher than that in a control group of patients with radical hysterectomy without PAND (10.5% vs 3.4%). However, in the PAND patients the postoperative ileus was mostly mild or moderate (10 mild cases, 15 moderate cases, and 3 severe cases). Severe ileus occurred in three patients with radical hysterectomy with PAND. Although a repeat operation was necessary for two of these three patients with severe ileus, they recovered uneventfully.


PAND for malignant gynecologic tumors is a feasible and safe operative procedure, with a low incidence of postoperative ileus.
