Objective:
To determine the accuracy of ultrasound in the assessment of proximal fallopian tube positioning of the Essure microinsert coil 3 months after postprocedure.
Design:
Prospective cohort study (Canadian Task Force classification II-2).
Setting:
Reproductive-age women in a tertiary care hospital.
Patient(S):
Reproductive-age women presenting with a request for permanent contraception.
Intervention(S):
Hysteroscopic sterilization with the Essure microinsert coil and conventional or volume-contrast three-dimensional (3D) ultrasound imaging 3 months after the procedure.
Main Outcome Measure(S):
Coil position on ultrasound.
Result(S):
Forty-eight of the 50 patients had successful placement of the Essure coils, and three patients required a second attempt on one tube. Conventional or volume-contrast (3D) ultrasound showed proper positioning of the coils within the proximal fallopian tube in 42 women (84%); five women (10%) required hysterosalpingogram to show appropriate positioning. Two patients (4%) required laparoscopic tubal sterilization, and one patient (2%) was lost to follow-up.
Conclusion(S):
Transvaginal ultrasound is an acceptable method of confirming proper placement of the Essure microinsert coil within the proximal fallopian tube 3 months after the procedure.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
