Therapy for children with appendiceal abscess remains controversial. The authors present two such cases initially treated conservatively, without interval appendectomy, that later had recurrent appendicitis. An 8-year-old boy presented with fever, abdominal pain, and a right-lower-quadrant abscess (noted by ultrasonography). ⋯ Interval appendectomy was refused. The patient returned 8 months later with recurrent acute appendicitis and an appendiceal abscess requiring appendectomy and drainage. Although initial drainage alone of appendiceal abscess is efficacious, the authors strongly advocate interval appendectomy as a critical component of the complete management of this entity.

Abdominal CO2 insufflation has been shown to cause hypercarbia, acidemia, and decreased oxygenation in a pediatric animal model. Such metabolic derangements have prompted a search for alternative insufflation gases. This study compares the hemodynamic and ventilatory changes that occur during pneumoperitoneum with CO2 and helium. ⋯ Abdominal insufflation with CO2 or helium causes hypercarbia, acidemia, and increased ETCO2 in this juvenile animal model. These derangements are significantly less with helium. This gas may prove to be the more suitable insufflation agent for pediatric patients.
