Background: An obscured vision of surgical field during laparoscopic surgery is inconvenient. Several temporary methods were described as solutions to loss of vision, and common practice is scope removal, cleaning, and heating. A lately developed and introduced device claims continuous clear vision during laparoscopic surgery. This study aims to present our initial experience with the device during laparoscopic colorectal surgery. Materials and Methods: We have included medical records of all patients scheduled for laparoscopic colorectal surgery with the device between March and August 2021 at Cleveland Clinic. Patient demographics, surgery type and time, the number of loss of vision events were recorded. Results: Fifteen patients underwent laparoscopic colorectal surgery during the study period. The median age was 42 (range: 25 to 86) years, and 10 (66%) were female. The median surgery time was 127 (range: 67 to 240) minutes, and the median loss of vision event number was 3 (1 to 6) per surgery. There was no need for laparoscope removal during any of the surgeries. All surgeries were completed without any intraoperative complications. Conclusion: The novel system, provides clear vision during laparoscopic colorectal surgery with no need of scope removal for loss of vision events. The system provides removal of particulate gathering on the tip of the scope.
