title: The effect of nonperitonization and laparoscopic lymphadenectomy for minimizing the incidence of lymphocyst formation after radical hysterectomy for cervical cancer.
abstract: OBJECTIVE
  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.
  
  
  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.
