Purpose: In recent studies, laparoscopic appendectomy has been widely performed for not only uncomplicated appendicitis but also perforated appendicitis. But, in children, the value of laparoscopic appendectomy for acute appendicitis is not yet established. Our retrospective study is to evaluate the safety of laparoscopic surgery for acute appendicitis in children. Methods: We reviewed electronic medical records of a total of 595 patients (95 children and 500 adults), who had been operated upon for acute appendicitis, from August 2005 to February 2007. Those patients were divided into two groups; children and adults. Demographic data, duration of pain, diagnostic methods, length of stay, operative time, time under anesthetic, time to diet, perforation rate, and complication rates were analyzed. Results: In eight adult patients, laparoscopic surgery was converted to open laparatomy. There was no significant difference in perforation rates (children 20.0% vs. adults 18.1%, P=0.714). However, postoperative complication rates were significantly higher in the children group (7.4%) compared to the adult group (2.2%). Conclusion: We noted that laparoscopic appendectomy should be applied cautiously, especially in pediatric groups due to the relatively high complication rate. However, we need to see more high-quality randomized trials.

Primary retroperitoneal teratomas are rarely seen in adults. They occur mostly in children. They are usually asymptomatic in adults, but they may cause symptoms due to tumor compression. As the tumors grow larger, palpable abdominal mass, progressive abdominal distension, abdominal pain, and even nausea and vomiting are occasionally noted. The diagnosis of retroperitoneal teratoma can be made accurately by CT scan. And ultrasonography and magnetic resonance(MR) imaging are also a helpful tools in delineating the precise position. Retroperitoneal teratomas should be surgically removed if possible, regardless of where they are benign or malignant because histologically benign ones may eventually prove fatal due to continued growth. We report a huge (12 x 7 x 9.5 em) primary retroperitoneal teratoma which were found incidentally and complete resected in a 27-year-old female patient.

Gastrointestinal tumors(GIST) are rare group of neoplasias of the gastrointestinal track, which originate from or differentiate into interstitial cells of Cajal (ICC). GIST traditionally have been designated as smooth muscle tumor. However, with increasingly accurate analytic tools, immunohistochemistry and ultrastructure, most investigators were able to demonstrate that ICC, a complex cellular network postulated to act as pacemaker cells of the gastrointestinal track, which exhibit both myoid and neural features, could be a candidate for tumor histogenesis. Most ICC are only c-kit-positive, however a subset are positive for both c-kit and CD34. Most GISTs are asymptomatic and are thus usually discovered incidentally during routine check, at operation of other organs. When symptoms occur, GISTs usually present with gastrointestinal bleeding due to ulceration of the overlying gastric mucosa. Bleeding may be massive, leading to hematemesis and melena. Recently, we experienced a large sized(5×5×5 cm) GIST on the upper body of the stomach, which caused massive upper gastrointestinal bleeding in a 61-year-old man and was treated by local resection with adequate safety margin about 2 cm.
