Abstract:
One-third of all cases of abdominal pain and a quarter of cases of right iliac fossa pain urgently admitted to hospital leave hospital with no precise diagnosis. Based on a series of 400 patients hospitalised for right iliac fossa pain, comprising 107 cases with no identified aetiology, this prospective study was designed to assess the medium-term outcome of these patients, with or without surgical exploration. 67 cases were reviewed at five years. No major diagnosis was missed. Over this 5-year period, 30 patients (45%) experienced another episode of abdominal pain. Among the third of patients (21 cases, 31%) reviewed for another episode of right iliac fossa pain, 7 were readmitted to hospital, with 5 operations, for histologically confirmed acute appendicitis in 3 cases (5% of the series). The patient and his attending physician must be informed of the nonspecific diagnosis established during the first hospitalisation. There is no significant evidence to suggest a psychological component in the recurrent nature of the pain. Cancer must be formally excluded in patients over the age of 50. When surgical exploration is performed, nowadays by laparoscopy, appendicectomy is recommended. This procedure does not decrease the risk of recurrent pain, but confirms the real absence of histopathological abnormality and decreases the number of subsequent hospitalisations.
