Nonoperative treatment with antibiotics versus surgery for acute nonperforated appendicitis in children: a pilot randomized controlled trial.

OBJECTIVE: The aim of this study was to evaluate the feasibility and safety of nonoperative treatment of acute nonperforated appendicitis with antibiotics in children. METHODS: A pilot randomized controlled trial was performed comparing nonoperative treatment with antibiotics versus surgery for acute appendicitis in children. Patients with imaging-confirmed acute nonperforated appendicitis who would normally have had emergency appendectomy were randomized either to treatment with antibiotics or to surgery. Follow-up was for 1 year. RESULTS: Fifty patients were enrolled; 26 were randomized to surgery and 24 to nonoperative treatment with antibiotics. All children in the surgery group had histopathologically confirmed acute appendicitis, and there were no significant complications in this group. Two of 24 patients in the nonoperative treatment group had appendectomy within the time of primary antibiotic treatment and 1 patient after 9 months for recurrent acute appendicitis. Another 6 patients have had an appendectomy due to recurrent abdominal pain (n = 5) or parental wish (n = 1) during the follow-up period; none of these 6 patients had evidence of appendicitis on histopathological examination. CONCLUSIONS: Twenty-two of 24 patients (92%) treated with antibiotics had initial resolution of symptoms. Of these 22, only 1 patient (5%) had recurrence of acute appendicitis during follow-up. Overall, 62% of patients have not had an appendectomy during the follow-up period. This pilot trial suggests that nonoperative treatment of acute appendicitis in children is feasible and safe and that further investigation of nonoperative treatment is warranted.

Surgery for hydrocele in children-an avoidable excess?

BACKGROUND: There is little consensus over the optimal timing of ligation of a patent processus vaginalis (PPV) in boys with hydrocele. We hypothesized that a proportion of procedures may be unnecessary because they are performed at an age before which the PPV may be expected to close spontaneously. Such excess may expose the child to unnecessary surgery and have significant cost implications. METHODS: A systematic literature review relating to timing of PPV ligation and a population-based study to define number of PPV ligations performed annually in England and age at surgery were conducted. RESULTS: Most hydroceles resolve before 2 years of age, but their natural history beyond this age is poorly documented. Current guidelines recommend PPV ligation at 2 years of age. An average of 2878 operations for hydrocele is performed per year in children in England. Commonest age at repair is 2 years. There are no randomized controlled trials comparing PPV ligation with an observational nonoperative approach. CONCLUSIONS: The natural history of hydrocele is poorly documented beyond the age of 2 years. There is no good evidence to support current practice. Delaying surgery may reduce the number of procedures necessary without increasing morbidity. A prospective study to investigate this is warranted.

Acute neonatal arterial occlusion: is thrombolysis safe and effective?

PURPOSE: We report our experience of the management of arterial occlusion in the newborn. METHODS: A case note review was carried out after ethical approval. Doppler ultrasonography confirmed the occlusion. Thrombolysis was the primary intervention. Surgery was used selectively. A good outcome was one without tissue loss or functional impairment or minimal tissue loss without functional impairment. Data are presented as medians with ranges. RESULTS: Ten patients (9 male; median gestational age, 35.5 weeks [range, 28-39 weeks]) presented on day 1 (range, 1-8 days). Initial management included systemic tissue plasminogen activator (8 patients) and surgery (2 infants in whom thrombolysis was contraindicated). Improvement was noted in 7 of 8 infants treated medically and in both who underwent surgery. Three infants had significant tissue loss. Outcome at 29 months (range, 1.3-95.4 months) was good in the remaining 7. CONCLUSIONS: A multidisciplinary approach, thrombolysis and selective surgery achieved tissue preservation and function in the majority while minimizing complications. Early referral to centers with multidisciplinary teams is recommended.
