Interval appendectomy: an old new operation.
A retrospective chart review of 32 patients who underwent laparoscopic interval appendectomy at the Children's Hospital of Eastern Ontario between May 1999 and December 2003 was performed. The age range was 0.5 to 18 years (mean, 11.8 years; median, 11.5 years). The interval time from the acute episode to the laparoscopic interval appendectomy ranged from 1 to 16 weeks (median, 6 weeks). The initial presentations were 11 patients with appendiceal abscess, 9 with appendiceal masses/phlegmons, and 12 patients with an acute but resolving clinical picture with ultrasonographic evidence of appendicitis. There were no wound infections or recurrent intra-abdominal abscesses. The average length of stay was 1.38 days, ranging from same-day discharge (1 patient) to a three-night stay (2 patients). There were no complications related to the laparoscopic technique, confirming reports that laparoscopic interval appendectomy is a technically safe procedure. Pathologic analysis of the appendices demonstrated acute or subacute changes in 14 patients (interval time = 7.9 weeks), chronic changes in 8 (interval time = 8.1 weeks), both acute and chronic changes in 5 (interval time = 8.2 weeks), and no pathologic diagnosis in 6 (interval time = 4.28 weeks). These findings support the need for interval appendectomy, and suggest that laparoscopy is a safe alternative to open appendectomy.
