Treatment of Acute Appendicitis in Pediatric Patients

Surgical Management

Laparoscopic appendectomy is the recommended first-line treatment for acute appendicitis in pediatric patients, with surgery performed within 24 hours of admission and within 8 hours for complicated cases, as recommended by the World Journal of Emergency Surgery 1, 2
Appendectomy should not be delayed beyond 24 hours from admission for uncomplicated appendicitis in pediatric patients 2
Early appendectomy (within 8 hours) should be performed for complicated appendicitis to reduce adverse outcomes 2
Laparoscopic appendectomy is strongly recommended over open appendectomy in children when laparoscopic equipment and expertise are available, offering benefits such as lower postoperative pain levels, lower incidence of surgical site infections, and higher quality of life outcomes 1, 3
Conventional three-port laparoscopic appendectomy is generally preferred over single-incision laparoscopic appendectomy due to shorter operative times, less postoperative pain, and lower incidence of wound infection 1

A single preoperative dose of broad-spectrum antibiotics should be administered 0-60 minutes before surgical incision to decrease wound infection and postoperative intra-abdominal abscess rates 4
For uncomplicated appendicitis, postoperative antibiotics are not recommended 4, 5
For complicated appendicitis, postoperative broad-spectrum antibiotics are indicated, with early switch to oral antibiotics (after 48 hours) and total antibiotic duration less than 7 days 5, 4

In settings without laparoscopic expertise, non-operative management with antibiotics and percutaneous drainage (if available) is suggested for appendiceal abscess or phlegmon 6
Where advanced laparoscopic expertise is available, laparoscopic approach is suggested as treatment of choice for appendiceal abscess or phlegmon 6
Routine interval appendectomy after successful non-operative management is not recommended in children, and should only be performed for children with recurrent symptoms 6

Outpatient laparoscopic appendectomy may be considered for uncomplicated appendicitis when an appropriate ambulatory setting is available, with well-defined enhanced recovery after surgery (ERAS) protocols and proper patient/family information and consent 1

Ultrasound is recommended as the first-line imaging method for suspected appendicitis in children, with clinical scoring systems (Alvarado Score, Pediatric Appendicitis Score) helping to risk-stratify patients and guide the need for imaging 7, 8
Point-of-care ultrasound (POCUS) is recommended as an appropriate first-line diagnostic tool if imaging is indicated based on clinical assessment 7

Atypical presentations are particularly common in preschool children under 5 years of age, which can lead to delayed diagnosis and higher perforation rates, as noted by the Journal of the American College of Radiology 9, 10
Perforation rates are higher in younger children, particularly those under 5 years of age, due to delayed presentation and diagnosis 9

The World Journal of Emergency Surgery recommends amoxicillin/clavulanate or ceftriaxone plus metronidazole as appropriate empiric choices for intra-abdominal infections 11

Non-operative management (NOM) with antibiotics can be discussed as an alternative to surgery in selected children with uncomplicated appendicitis in the absence of an appendicolith, with success rates approximately 63-73% at one year 11, 12
The presence of an appendicolith significantly increases failure rate, and surgery is recommended in such cases 11, 12
NOM is associated with higher readmission rates compared to appendectomy 11, 12
A minimum 48 hours of inpatient intravenous antibiotics followed by oral antibiotics for a total duration of 7-10 days is recommended for NOM 11, 12
