[Postoperative hemorrhage after tonsillectomy in Denmark].

Abstract

Removal of the tonsils, or tonsillectomy, is a very frequent surgical procedure in Denmark (5 million inhabitants). Nowadays, about 7-8,000 patients are operated on each year. The indications for surgery and the surgical principles have largely remained the same for a century, but different techniques have been employed. As in all surgical procedures, there are complications to tonsillectomy, first and foremost postoperative bleeding which occurs in 4-8% of all operated patients. In the last 100 years many studies have been undertaken to shed light on the frequency of postoperative bleeding following tonsillectomy. It is noteworthy that the studies have been carried out at times where there was a certain interest in the subject whereas in other periods of time, the subject has been of little interest to researchers. The definition of postoperative hemorrhage is not unambiguous. Despite the fact that various surgical techniques have been applied, no significant change in the incidence of postoperative hemorrhage after tonsillectomy has been shown over the past 100 years. The study calls for caution when evaluating new surgical techniques since the incidences of postoperative hemorrhage have been shown to change between high and low percentages through the entire 100 year period.
