Primaire uitkomstmaten
The primary outcome measure was pain scored by the blinded patient at 6 months postoperatively in the presence of the still blinded surgical resident.
Achtergrond van het onderzoek
Background:
It is questionable whether elective appendectomy can effectively reduce pain in persistent or recurrent right lower abdominal quadrant pain due to chronic or recurrent appendicitis.
Methods:
A single centre randomised double-blind sham surgery controlled clinical trial studied the effects of elective laparoscopic appendectomy on postoperative pain perception in selected patients with persistent or recurrent lower abdominal quadrant pain on abdominal pain level at 6 months postoperatively. Secondary outcome was the relation between clinical response and the appendix’ histopathology. The analysis was performed on an intention-to-treat basis. Pain scores were compared using a Fisher’s exact test.
Results:
Forty patients were randomised, 18 patients had a laparoscopic appendectomy and 22 patients had a laparoscopic inspection only. The postoperative pain scores were significantly different favouring appendix removal (p < 0.01). Relative risk calculations indicated a 2.4 fold (95% CI: 1.3 – 4.0) greater chance of improving or becoming pain free after laparoscopic appendectomy. The number needed to treat was 2.2 patients (95% CI: 1.5 – 6.5). However, there was no significant relation between postoperative pain scores and histopathology findings.
Conclusions:
Chronic or recurrent appendicitis is a realistic clinical entity that can be treated successfully by elective appendectomy leading to significant pain reduction in properly selected cases. Histopathology of the removed appendix does not contribute to the diagnosis.
