[Gastroesophageal reflux surgery in Denmark 1997-1999]

The incidence and length of postoperative stay in hospital in Denmark after oesophageal reflux surgery has not been described previously.

We examined the national patient hospital register and discharge information from the hospitals for the number of reflux operations carried out, the length of postoperative hospital stay, readmissions, and postoperative complications occurring within 30 days in the period, 1997-1999.

Twenty-four departments performed 4.9 operations/100,000 inhabitants per year, corresponding to 788 operations. The postoperative 30-day mortality was 0.4% and 6.6% of the operations were followed by serious surgical complications. The combined primary + readmission hospital stay was 3.7 days in the first postoperative month.

The small number of oesophageal reflux operations performed in many departments in Denmark is not in agreement with the Danish National Board of Health recommendations from 1996, which say that the operations should be done in only five departments. The spreading of surgery means that only few surgeons can reach sufficient training of surgery and that statistical comparison between the departments of the early results of treatment is not meaningful. Overall, national results are comparable to international results. The incidence of oesophageal reflux surgery is about three times lower than in other Scandinavian countries. On these results, it is recommended that the operation is performed in fewer departments and by fewer surgeons.
