[A comparative study of the suction and customary curettage methods in the termination of pregnancy (author's...

90 hysteroscopies using CO2 were performed to evaluate differences in effectiveness between the customary curettage and the suction methods in terminating pregnancy during the first trimenon. Following suction, the uterine cavity was nearly always thoroughly evacuated. Very seldom is there any residual tissue seen. On the contrary, the uterine cavity following termination by customary curettage was almost never completely evacuated. Very often rest tissue of decidua, usually chorionic, in some cases with villous structures, were found. Tissue remnants following termination by either method were removed by target biopsy or curettage and examined histologically. Having made the above observations and comparison, it must be concluded that the suction method is clearly the more advantageous. If applied correctly, it becomes unnecessary to perform curettage right after the suction.
