title: [Value of laparoscopic virtual reality simulator in laparoscopic suture ability training of catechumen].
abstract: OBJECTIVE
  To investigate the value of laparoscopic virtual reality simulator in laparoscopic suture ability training of catechumen.
  
  
  METHODS
  After finishing the virtual reality training of basic laparoscopic skills, 26 catechumen were divided randomly into 2 groups, one group undertook advanced laparoscopic skill (suture technique) training with laparoscopic virtual reality simulator (virtual group), another used laparoscopic box trainer (box group). Using our homemade simulations, before grouping and after training, every trainee performed nephropyeloureterostomy under laparoscopy, the running time, anastomosis quality and proficiency were recorded and assessed.
  
  
  RESULTS
  For virtual group, the running time, anastomosis quality and proficiency scores before grouping were (98 ± 11) minutes, 3.20 ± 0.41, 3.47 ± 0.64, respectively, after training were (53 ± 8) minutes, 6.87 ± 0.74, 6.33 ± 0.82, respectively, all the differences were statistically significant (all P < 0.01). In box group, before grouping were (98 ± 10) minutes, 3.17 ± 0.39, 3.42 ± 0.67, respectively, after training were (52 ± 9) minutes, 6.08 ± 0.90, 6.33 ± 0.78, respectively, all the differences also were statistically significant (all P < 0.01). After training, the running time and proficiency scores of virtual group were similar to box group (all P > 0.05), however, anstomosis quality scores in virtual group were higher than in box group (P = 0.02).
  
  
  CONCLUSIONS
  The laparoscopic virtual reality simulator is better than traditional box trainer in advanced laparoscopic suture ability training of catechumen.
