A computer system plays an indispensable role not only for correctly filing information of the radiographic and endoscopic diagnoses but also for referring to cases which should be placed on follow-up examination. It is also the best tool for a comparative study of the radiographic and endoscopic diagnoses. Modification of IRD (Index for Roentgen Diagnoses) was attempted in order to use the computer system for processing information of radiographic and endoscopic diagnoses of the gastrointestinal tracts, based on the result of the past year. IRD consists of anatomical fields and pathological fields. In this paper the anatomical fields are called "location codes" and pathological fields are called, "diagnosis codes". The main points of the modification are as follows. 1) Modification of the location codesCodes expressing the anterior wall, posterior wall, lesser curvature and greater curvature were made by adding a forth digit. A code for anastomosis and sature line was added. 2) Modification of diagnosis codesCodes expressing peptic ulcer were largely modified in order to reveal the present situation of radiographic and endoscopic diagnosis in Japan. Codes for erosion (s) were added. Codes for malignant neoplasm were vastly modified, following the classifications of Borrmann and early gastric cancer which should be used for cancer of the entire gastrointestinal tracts. A year of actual use and testing at our hospital has proven that the modified IRD is useful and practical on the computer. Establishment of the coding system for the diagnoses is very important as the first step of installing the computer system.
