ABSTRACT:
A system and a method for evaluation of gastrointestinal function is presented. The system consists of a catheter, a recorder and software. The catheter includes one or more CdTe sensors for measuring isotope activity. The catheter CdTe sensors are placed in the gastrointestinal tract to measure gastric emptying or gastrointestinal output after administration of radiolabeled liquid or solid meals. Data is stored in the recorder or displayed on-line on a computer screen. Other parameters such as pH can be added for a more complete evaluation of gastrointestinal function. The computer software is written for the Windows environment. The software includes provisions for general ambulatory and stationary data acquisition. The software also includes realtime analysis combined with an extensive patient journal where all items are described as objects in understandable userfriendly language connected to a database. With the present invention it is for the first time made possible to study gastrointestinal output and gastric emptying on an ambulatory basis.
