I am a nurse endoscopist in england. Endoscopy is increasing with the national bowel cancer screening. I undertake Gastroscopy and Colonoscopy both diagnostic and therapeutic. Nothing will ever replace being able to carry out therapeutics like removing polyps and taking Biopsies. The camera PILL is more for small bowel disease mainly for occult blood loss. There are nurses here that read the pictures and set up the electronics but I think it is a fairly tedious job. CT colonosgraphy ( 3 D Immaging ) is the biggest threat to us however you have to weigh up the risk of Xray if this is being used to screen people. I would say develop whre you can and go for it.
