Core Tip
Core Tip: Consent taking is important in endoscopic procedures so as to optimize procedural safety and patient outcomes. This is ethically important as part of good endoscopic practice. The process of consent taking is suboptimal in Nigeria. Specific measures such as training workshops and online webinars for endoscopists should be regularly held to improve the process in Nigeria.
