As surgeons gain more experience with laparoscopy in children, it is becoming apparent that one of the best applications of the technique is for appendicitis. The advantages of laparoscopic appendectomy include a better cosmetic result, particularly in young female patients, a shorter recovery time, and an early return to normal activities. In the differential diagnosis of appendicitis, the association of Enterobius vermicularis (pinworms) inflammation in the pediatric age group is not uncommon. The endo-loop technique for laparoscopic appendectomy is the standard technique used in our department. In three patients with E. vermicularis undergoing appendix removal using this technique, pinworms were found to be set free into the abdomen after dividing the appendix between the loop ligatures. Bipolar coagulating forceps were used carefully to thermally desiccate the worms, which were then removed using a blunt grasper. E. vermicularis being released into the abdomen in children undergoing laparoscopic appendectomy using the endo-loop technique has not been reported. Careful evaluation of the appendix stump and simple but careful thermal desiccation and removal of pinworms, if present, must be considered when using the endo-loop technique.
