- The aim of this study was to investigate mortality following elective and emergency groin hernia surgery. Information concerning 17 591 inguinal and 579 femoral hernia operations, including death of patients within 30 days of surgery, were prospectively recorded in the Swedish Hernia Register over a period of six years. Elective surgery for groin hernia is known to be a low-risk procedure. Mortality within 30 days of surgery was compared with the mortality of the general Swedish population using the standard mortality rate (SMR). Of all inguinal and femoral hernia repairs 5.1 % and 35.2 % respectively, were performed as an emergency. Following elective inguinal hernia repair the SMR for men fell significantly below unity. No significant differences between observed and expected mortality were observed following inguinal hernia surgery on females or following elective femoral hernia surgery on either gender. The reduced SMR found after elective hernia repair in men is most likely attributable to patient selection. After elective surgery on patients 70 years or older there is a tendency towards a reduction in SMR of the same order of size as for patients analysed as one group which, however, did not reach statistical significance. Mortality following both inguinal and femoral emergency procedures is increased five- to ten-fold compared to the 30-day mortality in the general population. A further increase in postoperative mortality is noted following emergency surgery with bowel resection.

- OBJECTIVE: Analysis of reoperation and recurrence rates three years after repair of groin hernias.DESIGN: Prospective audit by questionnaire and selective follow-up.SETTING: Eight Swedish hospitals.SUBJECTS: All groin hernia operations done during 1992 on patients between the ages of 15 and 80 years.MAIN OUTCOME MEASURES: Postoperative complications, reoperation for recurrence, and recurrence.RESULTS: During 1992, 1565 hernia operations were done. The postoperative complication rate was 8% (125/1565). At 36 months postoperatively 108 recurrences had already been reoperated on, six patients with recurrences were on the waiting list for reoperation and a further 36 recurrences had been detected at follow-up. The interhospital variation in recurrence rate ranged from 3% to 20%. Postoperative complications, recurrent hernia, direct hernia and hospital catchment area over 100000 inhabitants were all factors associated with an increased relative risk of recurrence.CONCLUSIONS: The recurrence rate exceeded the reoperation rate for recurrence by almost 40% which should be taken into account if the reoperation rate is used as the endpoint after repairs of groin hernia. An audit scheme, based on prospective recording, reoperation rate, and (periodic) calculation of the recurrence rate may be used to identify risk factors for recurrence and areas in need of improvement.

- BackgroundDifficulties in obtaining and analysing outcome measures in hernia surgery may be an obstacle to necessary progress in non-specialized hospitals. Against this background a voluntary register was initiated in 1992 with the aim of describing and evaluating hernia surgery in participating units.MethodsProspective registration of all hernia operations carried out in participating hospitals was undertaken using identification codes specific for each individual. Repair technique, complications, day surgery, type of anaesthesia, and reoperation for recurrence were recorded. Actuarial analysis was used to determine the cumulative incidence of reoperation. Relative risk for reoperation was estimated by the Cox proportional hazards model.ResultsThe number of participating hospitals and registered operations increased from eight and 1689 respectively in 1992 to 21 and 4056 in 1996. The use of mesh increased from 7 per cent of all operations in 1992 to 51 per cent in 1996. The proportion of operations done for recurrent hernia remained constant at 16–17 per cent throughout the 5-year study period. For all 12 542 herniorrhaphies registered, the cumulative incidence of reoperation at 2 years was 3 (95 per cent confidence interval 3–4) per cent. Postoperative complications, recurrent hernia, direct hernia and absorbable suture were associated with increased risk of reoperation for recurrence. An increased incidence of reoperation, although not statistically significant, was noted for conventional open repairs (Bassini, McVay, Marcy and others) versus the Shouldice technique.ConclusionIn this prospective audit an increasing use of mesh was observed for open and laparoscopic surgery, especially for bilateral and recurrent hernia operations. Reoperation rates decreased significantly between 1992 and 1995.

- From 1 January 1992 to 31 December 1997 18,281 inguinal hernias and 588 femoral hernias were recorded in the Swedish Hernia Register. The aim of the present study was to characterise these femoral hernias and to evaluate the reoperation rate following their repair. 64% of all femoral hernias were located in the right groin and 36% in the left groin (p < 0.001). The male to female ratio for femoral hernia was 1:1.6; mean ages of patients with femoral and inguinal hernia were 63.4 ± 17.1 and 59.1 ± 16.4 years, respectively (p < 0.001). Emergency surgery and bowel resection at emergency surgery were more common with femoral than with inguinal hernia. The rate of ambulatory surgery was lower for femoral hernia than for inguinal hernia, mainly due to the higher emergency rate for femoral hernia. At three years the cumulative incidence of reoperation was 4.6% (95% confidence interval 2.4–6.8%) for femoral hernia and 4.0% (95% confidence interval 3.6–4.4%) for inguinal hernia (p > 0.05). Male sex and postoperative complications were associated with a significantly increased risk of reoperation following femoral hernia repair. The relative risk of reoperation was not affected by patient age, elective/emergency surgery, primary/recurrent hernia or hernia side. Repair techniques using mesh were associated with a lower reoperation rate than techniques without mesh, although the difference did not reach statistical significance.
