title: Efficacy of 2-port laparoscopic surgery for gynecologic disease: invention of new suture technique.
abstract: OBJECTIVE
  To evaluate the efficacy and safety of 2-port laparoscopic surgery for ovarian tumors and uterine leiomyomas. A conventional slip knot under laparoscopic surgery is useful, but it is difficult for beginners. Therefore, we developed new suture technique.
  
  
  METHODS
  Between January 2011 and December 2012, 38 patients underwent 2-port total laparoscopic cystectomy (TLC); between January 2010 and December 2011, 45 patients underwent multiport (3 or 4 ports) TLC. Between January 2011 and December 2012, 25 patients underwent 2-port laparoscopic myomectomy (LM); between January 2010 and December 2011, 34 patients underwent multiport (3 or 4 ports) LM. Surgery time, blood loss, postoperative length of stay and complications were retrospectively compared in each group.
  
  
  RESULTS
  No significant differences in surgery time, blood loss or postoperative length of stay were found between 2-port TLC and multiport TLC. No significant differences were found in the aforementioned parameters between 2-port LM and multiport LM. We showed here a new suture technique 'intra-abdominal suturing/extra-abdominal traction method' instead of conventional slip knot.
  
  
  CONCLUSIONS
  We confirmed that 2-port TLC and LM are less invasive than conventional multiport laparoscopic surgery; furthermore, they are as safe as the conventional procedure. The new suture technique is easier than conventional slip knot and can applies sufficient tension to the suture knot for beginners.
