Randomized controlled trial evaluating the effect of the use of a laparoscopic lens-cleaning device during laparoscopic colorectal surgery on the multidimensional workload (YCOG1903).

There was no significant difference in the overall workload, but the physical demand and total number of lens washes outside the abdominal cavity were significantly lower in the Opclear® arm than in the warm saline arm. The use of this device may thus help reduce operator stress in terms of physical demand. The study was registered with the Japanese Clinical Trials Registry as UMIN0000038677.
