Abstract
AIM: To determine the ability of a groin ultrasound service to identify inguinal/femoral hernias in patients with groin pain and equivocal clinical signs, and to evaluate the number of positive cases undergoing surgery. METHODS AND MATERIALS: A retrospective review of 243 examinations performed during the period January 2000 to June 2004 was undertaken. The referral information, as well as details of the examination and subsequent follow-up, were obtained through our hospital/radiological information system. RESULTS: Of 243 patients, 92 (38%) were referrals from general practitioners and 151 (62%) were hospital referrals. The examinations were performed by radiology consultants or specialist registrars, the former accounting for 228 examinations (94%). The age range of the patients was 3 months to 88 years (mean age=48.7), with a male to female ratio of 3.2:1. One hundred and forty-three examinations were negative for hernias. Two of these patients underwent groin explorations and were found to be normal. The rest were discharged and none returned with related complaints. Ninety-four examinations (39%) were positive for hernias, as a result of which 62 patients underwent surgery. Of these, only four were found to be false-positives giving a positive predictive value of 94% in operated patients. Three scans were equivocal, and three were positive for other conditions. CONCLUSION: In patients with equivocal clinical signs, groin ultrasound is a useful tool for identifying hernias, and therefore, aids surgical management.
