title: Efficacy of using a novel endoscopic lens cleaning device: a prospective randomized controlled trial.
abstract: BACKGROUND
  Clear visualization of the surgical field is critical in laparoscopic surgery. The authors evaluated a device that does not necessitate an external cleaning process for the laparoscope. It was hypothesized that it will minimize the interruption in operative workflow.
  
  
  METHODS
  A total of 40 advanced laparoscopy patients were randomized to either the control or device group. Demographic data, procedural data, length of stay, frequency and duration of lens cleaning, and lens clarity scores (LCS) were recorded. Independent samples t test and Fisher's exact test were performed.
  
  
  RESULTS
  No significant difference was found between the device and control groups in demographic data, procedure time (P = .922) or LCS (P = .124). Laparoscope cleaning in the device group was significantly shorter than in the control group (P < .001). No complications were observed.
  
  
  CONCLUSIONS
  An intra-abdominal laparoscopic cleaning device can effectively clean the laparoscopic lens and lead to less workflow interruption. Although not documented in this study, it may also lead to shorter operative times.
