The average age was 52.4 years, and Male: female ratio was 10:1. The average interval from the previous operation to the detection was 13.9 years. The interval of the subgroup over 30 years of age at the first operation was shorter than that of the subgroup below 30 years. The highest incidence was found in anastomotic stoma (58.1%) and cardia (32.3%). Borrmann I was the most common pathological type. Confirmed diagnostic rate with fibergastroscope was 81.8%.
