Over the last few decades, paediatric gastroenterology has rapidly developed into a well-established sub-specialty. Improvements in training and equipment have led to enhanced safety with fewer complications following endoscopies. In specialized units, diagnostic and therapeutic upper gastrointestinal endoscopy and proctosigmoidoscopy/colonoscopy are regularly performed under conscious sedation or general anaesthesia. Emerging guidelines and new advances in the diagnostic tools are being incorporated into routine paediatric gastrointestinal endoscopy practice.
