It is not usually worth taking biopsies from the cardia unless there is macroscopic disease. Acute gastritis is characterized by infiltration of leucocytes, mucosal haemorrhages and erosions.
The capsule is swallowed and located in the body by positioning the receiving aerial on the skin over the maximal signal. The gastric pH can be measured directly, and if desired a complete pH profile of the gut obtained before recovery from the faeces. Intravenous 99m technetium Another approach is the IV injection of 99mtechnetium pertechnetate 15 minutes after SC administration of pentagastrin 6 Jlglkg. 87).

Scott-Harden tube This useful tube is used by the radiologist for rapid intubation of the duodenum so that barium can be introduced into the small bowel. The tube consists of a gently curved stiff outer tube, which is positioned in the stomach so that the distal end rests at the level of the pylorus. An inner tube is then slid out and inserted through the pylorus. With experience this can be undertaken with great ease and rapidity. The procedure is superior to the use of internal stiffening wires.
