Appendectomy was performed on 1,059 @entity1 at the University Clinic of Paediatric Surgery in Mainz from 1. 1. 1975 to 31. 6. 1983. For the retrospective examination of the indication for appendectomy histopathological and intraoperative findings were analysed and evaluated. Histologically five types of @entity698 were differentiated: 1. @entity697 (two forms: acute ulcero-phlegmonous @entity698 with or without perforation and acute superficial @entity698 ), 2. @entity102 , 3. @entity1373 , 4. @entity82 , 5. rare diseases. In 618 cases (= 58.3%) @entity697 was diagnosed histologically. In another 203 cases (= 19.2%) intraoperative findings (e.g. @entity3298 , Meckel's diverticulum) were retrospectively collected; they caused symptoms similar to those of @entity698 . However, there remain retrospectively 22% of all appendectomised @entity1 with no indication for laparotomy. The statistical analysis of @entity260 showed a significant dependance from the histopathological findings. The highest rate of complications was seen in cases with perforated (34%) or non-perforated (10%) ulcero-phlegmonous @entity698 . @entity1 with acute superficial @entity698 had a complication-rate of 5%; those with @entity1373 and @entity82 of 6% each. Relaparotomies were almost exclusively necessary in cases with @entity697 ; @entity358 were mostly seen either in @entity1 with @entity600 or other perinatal risks, or in @entity1 with additional severe diseases. Therefore non- @entity697 justifies a wide indication for appendectomy because of a low complication-rate; this, however, is not valid for high-risk @entity1 (e.g. @entity600 ). In these cases sonography might be useful for preoperative diagnosis.
