[Appendicitis in childhood].
Appendectomy was performed on 1,059 children 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 appendicitis were differentiated: 1. acute appendicitis (two forms: acute ulcero-phlegmonous appendicitis with or without perforation and acute superficial appendicitis), 2. chronic appendicitis, 3. lymphatic hyperplasia, 4. submucosal fibrosis, 5. rare diseases. In 618 cases (= 58.3%) acute appendicitis was diagnosed histologically. In another 203 cases (= 19.2%) intraoperative findings (e.g. Lymphadenitis mesenterialis, Meckel's diverticulum) were retrospectively collected; they caused symptoms similar to those of appendicitis. However, there remain retrospectively 22% of all appendectomised children with no indication for laparotomy. The statistical analysis of postoperative complications 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 appendicitis. Children with acute superficial appendicitis had a complication-rate of 5%; those with lymphatic hyperplasia and submucosal fibrosis of 6% each. Relaparotomies were almost exclusively necessary in cases with acute appendicitis; septic and pulmonary complications were mostly seen either in infants with malformations or other perinatal risks, or in children with additional severe diseases. Therefore non-acute appendicitis justifies a wide indication for appendectomy because of a low complication-rate; this, however, is not valid for high-risk children (e.g. malformations). In these cases sonography might be useful for preoperative diagnosis.
