Questionuaires in quiring the complications of gastro intestinal endoscopy were sent to 103 hospitals in YAMAGUCHI Prefecture, and the answer was obtained in 78.6% (81 hospitals). Gastrointestinal endoscopic examinations reported in 188, 428 cases and the examinations included upper gastrointestinal examinations (179, 057 cases), biopsy (21, 124) endoscopic polypectomy (329 cases), ERCP (1, 760 cases), Romanoscopy (6, 894 cases) and endoscopy in emergency (289 cases). The overall rate of complications was 0.05% (89 cases) and mortality rate was 0.004% (9 cases). Complications included hemorrhage (27 cases), perforation (12 cases) dislocation of jaw joints (11 cases), subcutaneDus emphy-sema (7 cases), laceration (6 cases), difficulty in removing (5 cases) and the others (20 cases). We made a comparative study of the past reports from the survey by Schindler (1940) to the survey of Japan by T. Takemoto (1975). Analysis of this survey indicated that complication of hemorrhage was more than perforation in number. This reason was thought by becoming widespread of biopsy and endoscopic polypectomy and coming into use of fiberoptic instruments in place of flexirid instruments. The value of gastrointestinal endoscopic examinations is now well established and the number of examination will be more on the increase. So the complications of endoscopic examination will increase in number. We must call attention to a potential risks of the complications.
