Laser laparoscopy in the treatment of endometriosis. A 5-year study

The carbon-dioxide laser used laparoscopically provides a precise and virtually bloodless technique for the vaporization of endometriotic implants in the pelvis. The technique has been used at St Luke's Hospital, Guildford, for the past 6 years and this report presents 228 consecutive patients with endometriosis treated during the 5 years between 1982 and 1987 and followed up for between 1 and 6 years. Pain was improved in 70% and 80% of the 56 infertile patients with endometriosis as the only identifiable abnormality conceived. Of the 54 pregnancies, only 37 (69%) had a successful outcome, reflecting the high pregnancy failure rate found in women with endometriosis. Hospital stay was relatively short and complications were few and usually minor and there was no injury or morbidity caused by laser energy. The main advantage of laser laparoscopy in endometriosis is that patients may be treated at the time of diagnosis with less need for medication and no delay before conception is attempted.
