Antibiotic Therapy vs Laparscopic Appendectomy in Pediatric Chronic Appendicitis
- Registration Number
- NCT03754387
- Lead Sponsor
- Zunyi Medical College
- Brief Summary
This clinical trial will compare antibiotic therapy with laparoscopic appendectomy in the treatment of pediatric chronic appendicitis in china. Enrolled patients will be randomised and an allocation ratio of 1:1 will be made via weighted minimisation, where half of the patients will receive antibiotic therapy with intravenous Ceftazidime sodium, while the other half will have a laparoscopic appendicectomy.
- Detailed Description
In recent years, nonoperative treatment has challenged appendectomy as a first-line treatment of acute uncomplicated appendicitis by demonstrating its safety and short-term efficacy in adults. Several randomized controlled trials comparing appendectomy to antibiotics alone in children with acute uncomplicated appendicitis have been reported from other countries. These studies reveal that non-operative management of appendicitis is a safe treatment for appendicitis and is associated with a significantly lower risk of complications than appendectomy. However, the success rate of nonoperative management was 75% at 1year. Chronic appendicitis has been described as a possible cause of persistent right lower quadrant (RLQ) pain and laparoscopic appendectomy has been shown to benefit a large number of children，but there are no high-quality clinical trials. There are more than 200 million children in China. According to preliminary clinical data, the incidence of pediatric appendicitis in China is higher than Europe and America. Due to the Chinese parents have different cultures and educational backgrounds, more high-quality clinical trials are needed to guide parents to choose appropriate treatment for chronic appendicitis in children. Therefore, the investigators propose a multi-institutional trial in which patients and their families choose between antibiotics therapy (AT group) or laparoscopic appendectomy (LAAPT group) to chronic appendicitis in children aged 3-15 years. The investigators hypothesize that laparoscopic appendectomy will be successful in 90% of patients at 1 year follow-up and will be associated with fewer disability days, higher quality of life scores, and higher pain reduce scores than antibiotic therapy. This study will enroll 200 patients, age 3-15 years, with chronic appendicitis at 8-10 hospitals.

- Arm && Interventions
Group Intervention Description Laparoscopic Appendectomy group appendectomy Laparoscopic appendectomy will performed using. Prophylactic antibiotics (ceftazidime sodium 50mg/kg/dose ) will administered approximately 30 minutes before the incision was made. No further antibiotics will given to patients in the surgical group unless a wound infection was suspected postoperatively. Antibiotic therapy group Ceftazidime Ceftazidime will chosen as the antibiotic for this study because of its efficacy as a monotherapy for serious intraabdominal infections, requiring only a single, daily dose. Intravenous Ceftazidime sodium (50mg/kg/dose every 12 hours) is administered for 3 days to patients in the AT group, with the first dose given in the emergency department. The clinical status of patients in the AT group is reevaluated within 12 to 24 hours after admission by the surgeon on call. If the surgeon suspected progressive infection, perforated appendicitis, or peritonitis, the patient will underwent appendectomy. Intravenous antibiotic treatment will followed by 7 days of oral cefuroxime (250mg twice daily).
- Primary Outcome Measures
Name Time Method Success rate 1 year The primary end point for patients in the antibiotic therapy group is resolution of chronic appendicitis, resulting in discharge from the hospital without the need for surgical intervention and no recurrent appendicitis during a minimum follow-up of 1 year (treatment efficacy). Treatment success in the laparoscopic appendectomy group is defined as a patient successfully undergoing an laparoscopic appendectomy and no recurrent abdominal pain during a minimum follow-up of 1 year (treatment efficacy).
- Secondary Outcome Measures
Name Time Method Diarrhea 7 days Adverse effects of the antibiotic treatment during the conservation treatment
postintervention pain scores 1 year postintervention pain scores (VAS score range, 0-10; a score of 0 indicates no pain and 10 indicates the worst possible pain), and the use of pain medication.
Wound infection 30 days Postintervention complications included clinical wound infection (surgical site infection) occurring within 30 days after the operative procedure as diagnosed by a surgeon or with a positive bacterial culture.
The rate of recurrence 1 year late recurrence (after 1 year) of chronic appendicitis after conservative treatment, length of hospital stay and the amount of sick leave used by the patient.
pneumonia 7days Postintervention complication included pneumonia occurring within 7days after the operative procedure as diagnosed by clinical presentation and chest X-ray or CT-scan.
persistent abdominal or incisional pain 1 year Postintervention complication included persistent abdominal or incisional pain occurring within1year after the operative procedure as diagnosed by surgeon .
Incisional hernia 1 year Postintervention complication included incisional hernia occurring within1year after the operative procedure as diagnosed by surgeon .
Bowel obstruction 1 year Postintervention complication included bowel obstruction occurring within1year after the operative procedure as diagnosed by clinical presentation and abdominal X-ray or CT-scan.
