This morning to King's for a capsule endoscopy. The patient (who has had intestines cleared by a powerful laxative) swallows an 11 x 26 mm capsule weighing about 4 gm, containing a colour video camera and wireless radiofrequency transmitter, 4 LED lights, and enough battery power to take 50,000 color images during an 8-hour journey through the digestive tract. The capsule is made of specially sealed biocompatible material that is resistant to stomach acid and powerful digestive enzymes. It moves through the digestive tract with the peristaltic activity of the intestinal muscles, transmitting images to special antenna pads placed on the body and captured on a recording device about the size of a portable Walkman strapped to the patient's waist. The device has flashing lights and could be mistaken for something more sinister, so the hospital issues a letter to be shown to a police officer if necessary.
