Background and aims: Women, on average, have smaller hand sizes as well as lower muscle mass and strength. With the increasing number of women entering training programs in gastroenterology, our aim was to study the subtle gender differences in endoscopy ergonomics.
Methods: A survey instrument regarding demographic information, personal preferences in endoscopy styles and techniques, and endoscopy-related injury was sent to practicing gastroenterologists. Statistical analysis was performed on the data.
Results: The survey was answered by 107 gastroenterologists, 41 (38.3%) female subjects and 66 (61.7%) male subjects. Female participants were shorter in height, had smaller hand sizes, and performed fewer weekly cases. More men (45.5%) than women (20%) performed advanced endoscopic procedures. Women preferred the following: (1) holding the endoscope with the umbilical cord outside the forearm; (2) using the right hand to turn the small wheel; and (3) using a pediatric colonoscope to perform colonoscopy in a petite patient or one with a low body mass index. Endoscopy-related injury was reported in 49.5% of all gastroenterologists, with women reporting a significantly higher risk of injury (63.4%) than men (40.9%) (P = .02). Although higher weekly case volumes and performance of advanced endoscopy procedures were not independent risk factors for endoscopy-related injury, female gender was found to be an independent risk factor for injury.
Conclusions: Gender differences exist in endoscopy styles and techniques, as well as endoscopy-related injury. Providing gender-specific training in endoscopy may improve ergonomics and decrease the risk of injury.
