Laparoscopic sterilization with an elasticated silicone ring

A method of laparoscopic sterilization using an elasticated silicone ring is described. It was used in 155 patients over a period of 13 months by 12 gynaecologists. There were 12 complications specifically related to the method and only one of them required laparotomy. One tubal patency was discovered, but no pregnancy occurred in a total follow-up period of 81-25 years. Many patients had pain in the first 24 hours after operation but only 3 per cent had pain after three months.
