title: The use of carbon dioxide laser laparoscopy in the treatment of tubal ectopic pregnancies.
abstract: OBJECTIVE
  The purpose of this study was to assess the efficacy of the treatment of unruptured tubal ectopic pregnancies by the use of carbon dioxide laser laparoscopy.
  
  
  METHODS
  A series of 125 consecutive ectopic pregnancies were treated laparoscopically; the tubal pregnancy was removed by a laparoscopic laser technique. Preoperative assessment included monitoring beta-human chorionic gonadotropin levels, use of vaginal ultrasonography, and preoperative and postoperative hematocrit levels.
  
  
  RESULTS
  Laparoscopic laser surgery was successful for removal of tubal ectopic pregnancies in all but four patients, in whom a laparotomy was required. Hematocrit levels before and after surgery were similar. The time necessary for beta-human chorionic gonadotropin to fall to nondetectable levels averaged between 3 and 4 weeks. There were five patients who had complications requiring additional surgery and/or medical treatment.
  
  
  CONCLUSIONS
  The techniques are easy to learn, and the use of laparoscopic laser surgery in the treatment of tubal ectopic pregnancies appears to be a safe procedure with definite advantages for both the patient and the physician. There are decreased operating times, shorter hospital stays, and lower medical costs compared with those for major surgery. Subsequent successful intrauterine pregnancy rates are comparable to those of conservative methods previously reported.
