Abstract BACKGROUND: Groin hernia repair is one of the most frequent operations, but there is no consensus about surgical or anaesthetic technique. Furthermore, no nationwide studies have been done. Our aim was to investigate outcome results of groin hernia surgery to improve quality of treatment. METHODS: We prospectively recorded 26304 groin hernia repairs done in Denmark from Jan 1, 1998, to June 30, 2000, in a nationwide Danish hernia database. FINDINGS: 93\% of all groin herniorrhaphies done in Denmark in the 30 months of the study were recorded in the database. Kaplan-Meier estimates of reoperation rates 30 months after anterior mesh repair and laparoscopic repair were significantly lower than after sutured posterior wall repairs in primary inguinal hernia (2.2\% and 2.6\% vs 4.4\%; p<0.0001). Reoperation rates were also lower with anterior mesh repair (6.1\%; p<0.0001) and laparoscopic repair (3.4\%; p<0.0001) than with sutured posterior wall repair (10.6\%) after recurrent hernia. Use of Lichtenstein mesh repair increased from 33\% in January, 1998, to 62\% in June, 2000, whereas use of laparoscopic repair remained constant at about 5\%. Kaplan-Meier estimates of reoperation rates were 2.8\% in the first 15 months and 1.6\% in the second (p=0.03). For elective repairs, only 59\% of patients were treated on an outpatient basis, and only 18\% had local anaesthesia. INTERPRETATION: Mesh repairs have a lower reoperation rate than conventional open repairs. Systematic prospective recording of treatment and outcome variables in a national clinical database improved the overall quality of surgical care. However, there is a large potential for cost savings and more efficient patient care with extended use of mesh techniques, outpatient surgery, and local anaesthesia.
