Failures in outpatient tonsillectomy policy in children: a retrospective study in 311 children.

The literature suggests that outpatient tonsillectomy in children is a safe and cost-effective procedure. These conclusions have been based on the low rate of post-operative complications. Recent papers suggest contra-indications for ambulatory surgery in some patients. A retrospective study involving 311 children was performed in our Department. We defined two groups in which the out-patient policy had failed. The first group (43 children) comprised inpatient children scheduled because of an unhealthy preoperative state (12 patients), a sleep-apnea syndrome (5 children), a major associated procedure (3 patients), a social or family environment not reliable enough for postoperative supervision (19 patients) or because of parental refusal (4 patients). The second group (268 patients) was constituted of scheduled outpatients. In this group, the outpatient policy failed in 31 and children had to be kept overnight, because complications occurred. The main short-term complication was bleeding (13 patients). In 8, delayed complications were observed. Thus, according to the literature, children with concomitant heavy medical problems or with a poor social environment have to be managed as inpatients. For the others outpatient procedures were possible but parents should previously be informed of the possible overnight hospital supervision which is needed in 11.6% of cases. When comparing the youngest patients under 4 years of age with the others, although the preexisting medical and social conditions are important factors that may contraindicate ambulatory surgery, once the latter has been decided on, there is no significant difference between the two age groups regarding the number of children requiring overnight hospital supervision.
