Falope Rings or Modified Pomeroy's Technique for Concurrent Tubal Sterilization

Sterilization at caesarean section is usually performed by the modified Pomeroy's technique. Application of Falope rings and Filshie clips may also be used for tubal sterilization at caesarean section, and these techniques are also used during laparoscopy or minilaparotomy.

The main objective of the study was to evaluate the failure rates, complications, technical difficulties and reversibility of the Falope ring application for tubal sterilization as compared to the traditional modified Pomeroy's technique used during caesarean sections.

Five hundred multigravid women who underwent caesarean section for various causes and wanted concurrent tubal sterilization were recruited in the study. Two hundred and fifty women underwent tubal sterilization by Falope ring application and the other 250 by modified Pomeroy's technique. Follow-up period ranged from 3 to 42 months. These patients' names were checked against the antenatal booking register, the operating theatre register in case of ectopic pregnancies and a termination of pregnancy register to recognize failed sterilization.

Among the 250 women who underwent Falope ring application, no major complications were noted. In the other group, women who underwent tubal sterilization by modified Pomeroy's technique, there was one woman with serious complication, ectopic pregnancy. Falope ring application was an easy procedure to perform and also less time-consuming than modified Pomeroy's technique.

Falope ring sterilization is simple, effective and safe, and the rate of subsequent pregnancy is lower than with conventional modified Pomeroy's technique.
