Abstract

Background:
Although appendectomy is the most common emergency abdominal surgery, there is no epidemiologic study on chronic pain after open appendectomy. The aim of this study was to evaluate the incidence and possible risk factors of chronic pain following this common surgical procedure.

Methods:
In this cross-sectional survey, a questionnaire was completed regarding the pain at the surgical site by calling available patients who had undergone open appendectomy from 1999-2004 in a hospital in Fasa. The patients records were checked for the results of pathology.

Findings:
Out of 1130 patients operated by open appendectomy, 155 were available. The mean time left after appendectomy was 28 months. At the time of study, 41 (26%) patients still had pain at the site of operation and 9.85% of them had severe pain at rest and 22% suffered from severe pain during daily activities. Chronic pain was significantly more common among patients who had the memory of severe acute post-operative pain and there was no significant difference in the chronicity of pain according to age, sex and positive appendectomy.

Conclusion:
Chronic post-appendectomy pain is provalent. It is more common in patients with severe acute post-operative pain but it seems not to be related with age, sex, and positive appendectomy.
