title: An economic evaluation of laparoscopy and open surgery in the treatment of tubal pregnancy.
abstract: BACKGROUND
  Laparoscopy has generally replaced open surgery in the treatment of ectopic pregnancy. This study assesses the impact of the introduction of laparoscopy in the surgical treatment of tubal pregnancy on costs.
  
  
  METHODS
  Consecutive patients undergoing primary surgery for tubal pregnancy between January 1992 and December 1995 were included in the study. Surgery was performed laparoscopically or by open surgery. Cost for each treatment was calculated by multiplying resources used with calculated resource unit prices. The analysis was stratified for radical and conservative surgery.
  
  
  RESULTS
  Data of 255 patients were analysed. Tubal pregnancy was successfully treated in all patients. Costs per patient were US$ 3,490 for radical open surgery, US$ 1,872 for radical laparoscopic surgery, US$ 3420 for conservative open surgery and US$ 2,125 for conservative laparoscopic surgery. Differences in costs were caused by a decreased duration of hospital stay after laparoscopy, and, in case of conservative surgery, by an increased persistent trophoblast rate after laparoscopy.
  
  
  CONCLUSIONS
  Laparoscopy is equally effective as open surgery in the treatment of tubal pregnancy, and considerably reduces costs.
