Comparison of laparoscopic sterilization via spring-loaded clip and tubal ring.


The spring-loaded clip and tubal ring techniques of laparoscopic female sterilization were compared for ease of performance, safety and effectiveness at the Asociación Demográfica Salvadoreña in San Salvador, where they were randomly assigned to a total of 299 patients. Rates of technical/equipment difficulties and procedural difficulties during laparoscopy were similar for both techniques. Procedure-related surgical complications occurred in three ring patients as a result of tubal transection. Pain during the procedure was more severe for tubal ring patients. Results suggest that both techniques can be safely and effectively used for laparoscopic sterilization.


A study was conducted to assess the relative ease of performance, ring techniques of laparoscopic female sterilization. 299 randomly-assigned female clients at the Asociacion Demografica Salvadorena in San Salvador were used in the study. Demographic characteristics of the 2 patient groups, operative procedures, and resultant side effects and complications from the 2 procedures are discussed and tabulated. Rates of technical/equipment difficulties and procedureal difficulties during the laparoscopy were similar for the 2 methods. Pain during the procedure was more severe for the tubal ring patients; this difference did not continue into the recovery or early follow-up periods. 1 of each group of patients was considered a technical failure. Mean surgical time for both groups was under 8 minutes. Follow up at 6, 12, and 24 months showed very low failure (i.e., pregnancy) rates in both groups. It is concluded that both procedures can be safely performed on an outpatient basis, using only local anesthetics plus analgesics. Both are very effective.
