Laparoscopic tubal ligation. A follow-up report on the Yoon falope ring methodology.



The Yoon Falope Ring methodology was examined on a prospective basis in 2299 patients from October 1973 through June 1978. The Yoon Falope Ring, made of medical-grade silicone rubber, can be applied by single- or double-puncture laparoscopy, by minilaparotomy, or transvaginally by either colpotomy or the culdoscopic technique. The patients were followed at 6-month intervals when possible. An overall follow-up rate of 75%, for a total of 37,140 woman-months, was achieved. The most significant complication was tubal transection; this occurred in 76 (3.3%) of cases during the study period. To date, the overall pregnancy failure rate, excluding luteal phase pregnancy, is 0.42% per 100 woman-years. As a laparoscopic methodology its versatility is well suited for outpatient, local anesthetic use. Although serosal bowel application was encountered in 2 early cases, it does not pose the same potential morbidity as does the bowel burn associated with electrocoagulation. A ring application to the serosal surface of the bowel can be removed laparoscopically, whereas a burn to the bowel requires laparotomy for probable resection and reanastomosis of the involved area. Intraand post-operative pain may be slightly higher than with electrocoagulation but is less than with the Pomeroy procedure. The advantages of the technique are multiple. It is a simple, safe, effective and easily learned methodology. It eliminates the morbidity and mortality associated with coagulation sterilization. When used in a training program, it is easily adaptable to a variety of surgical approaches.
