A diverticulum is a blind pouch communicating with the gut. The term "diverticulitis" indicates inflammation of a diverticulum or diverticula, which is commonly accompanied by gross or microscopic perforation. Acute diverticuitis is a rare disorder in early childhood. Itis difficult to diagnose acute right colon diverticulitis from common causes of RLQ pain. We report a case of acute diverticulitis in the right colon in a 6-year-old girl. She complained of typical RLQ pain mimicking acute appendicitis,but was diagnosed with acute diverticulitis by CT scanning. Conservative treatment failed because of peritonitis due to perforation of an inflamed diverticulum. After the diverticulcetomy, the symptoms resolved.

For the efficient management of hospital sickbeds, it is important to predict the length of stay (LoS) of appendicitis patients. This study analyzed the patient data to find factors that show high positive correlation with LoS, build LoS prediction models using neural network and decision tree models, and compare their performance. In order to increase the prediction accuracy, we applied the ensemble techniques such as bagging and boosting. Experimental results show that decision tree model which was built with less number of variables shows prediction accuracy almost equal to that of neural network model, and that bagging is better than boosting. In conclusion, since the decision tree model which provides better explanation than neural network model can well predict the LoS of appendicitis patients and can also be used to select the input variables, it is recommended that hospitals make use of the decision tree techniques more actively.

A human case infected with Terranova type A larva was found in Korea. The patient was a 23-year old soldier of the Korean Army and the chief complaint was acute abdominal pain. The pain was chiefly at right lower quadrant. Appendectomy was performed under the clinical impression of acute appendicitis. However, during the surgery, a nematode larva was found moving on the serosal surface of terminal ileum. The worm was 25.76mm long and O. 66mm -wide, and had the intestinal cecum reaching to anterior one-third level of ventriculus and a mucron at posterior end. Therefore, it was diagnosed as Terranova type A larva. This is the first human case of Terranova type A larva infection in Korea.

Acute abdomen is a condition with sudden abdominal pain that may require immediate surgical treatment. The causes of acute abdomen in pediatric patients are diverse, and can be categorized in broad range from diseases requiring surgery to diseases requiring medication or clinical observation only. The role of the imaging study in children with acute abdomen is to distinguish between patients who need medication and patients who need surgery by identifying diseases that cause abdominal pain, if possible. Since intussusception and appendicitis are the leading causes of acute abdomen requiring surgical treatment in children, it is important to exclude intussusception in young infants complaining of acute abdominal pain and exclude acute appendicitis in older children with acute abdomen. In this paper, we introduce intussusception, acute appendicitis, midgut volvulus, Meckel's diverticulum and duplication cyst, which has characteristic imaging finding of the disease that can cause acute abdomen in pediatric patients.
