Objectives: To determine the clinical effect of nonperitonization and laparoscopic lymphadenectomy using bipolar electrocautery after radical hysterectomy for cervical cancer compared with peritonization and open lymphadenectomy using monopolar electrocautery.

Materials and Methods: This was a retrospective study of 180 patients who underwent a radical hysterectomy and pelvic lymph node dissection (PLND) for cervical cancer from August 1998 to August 2007. The patients were composed of the Peritonization + Laparotomy group (group A; n = 98, 196 PLND) and the Nonperitonization + Laparoscopy group (group B; n = 82, 164 PLND). Group B left the peritoneum in front of the PLND open. Two closed-suction drains were placed at each side of the PLND.

Results: Group B statistically showed a lesser total amount of lymphatic drainage (P = 0.001), shorter duration of inserted drains (P < 0.001), and shorter length of hospital stay (P < 0.001), compared with group A. The formation of lymphocysts occurred in 30 patients (41 lymphocysts) of group A and 5 patients (5 lymphocysts) of group B. Lymphocyst formation of group B had a statistically lower incidence than that of group A (P < 0.001). Lymphocyst formation was associated with an increase in the total amount of lymphatic drainage in group A (P = 0.090) and group B (P = 0.041) and a pathologic type of adenocarcinoma in group B (P = 0.016). Surgical experiences were not correlated with lymphocyst formation.

Conclusions: The omission of peritonization and laparoscopic lymphadenectomy using bipolar electrocautery in early-stage cervical cancer were more effective than peritonization and open lymphadenectomy using monopolar electrocautery in minimizing the incidence of lymphocyst formation.
