Mock video
Control group
The video of the intervention group will provide a short (< 5 min) summary explaining the basic principles of endoscopic extraperitoneal hernia repair, its possible complications and the postoperative course. After carefully watching the video, participants should be able to correctly answer to a multiple-choice test consisting of 12 questions related to the aforementioned topics.
This video is a general documentation of the "typical" day of surgery in the day clinic. The information is essentially limited to the pictorial representation of the individual wards which the patient will pass through during the operation (arrival at the clinic, admission, transport to the operating theatre, recovery room, discharge). The video explicitly does not transport any information that could be helpful for answering the quiz questions or for medical understanding of the operation itself.
The link of the third group leads to a digital version of the information sheet, which has already been discussed with all patients during the informed consent discussion. The digital version of the informed consent form allows the patient to read the information again. The third group thus corresponds to the standard of care.
