We propose that ultrasound imaging is more suited for this purpose and gives reassurance much earlier. The sonographic appearance of the micro\u2010inserts and the reliability of this modality in localising the devices is described in the present study.<\/jats:p><jats:p><jats:bold>Objective:\u2002<\/jats:bold> To ascertain the appearance of the Essure PBC device at transvaginal and transabdominal ultrasound scanning and to determine the reliability of this approach in localising the contraceptive device.<\/jats:p><jats:p><jats:bold>Study population and methods:\u2002<\/jats:bold> All patients who had the Essure PBC procedure between June 2002 and January 2003 at our centre were offered an ultrasound scan to check device position.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> The micro\u2010inserts were easily distinguished by their echogenic coil\u2010like appearance within each uterine cornua extending into the proximal fallopian tube. Of the 15 patients examined, 14 pairs of devices were seen: one device was malpositioned in the lower part of the uterus. In one patient, only one device was seen in the correct position but the other device was not identified and presumably expelled after a notably difficult insertion.<\/jats:p><jats:p><jats:bold>Discussion:\u2002<\/jats:bold> Ultrasound appears to be well suited for micro\u2010insert localisation. An early post insertion ultrasound scan is recommended to reassure about correct positioning of device and may potentially alleviate patient anxiety, or diagnose malposition early.<\/jats:p>","DOI":"10.1046\/j.0004-8666.2003.00102.x","type":"journal-article","created":{"date-parts":[[2003,10,15]],"date-time":"2003-10-15T21:53:03Z","timestamp":1066254783000},"page":"378-380","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["Ultrasound detection of the Essure permanent birth control device: A case series"],"prefix":"10.1111","volume":"43","author":[{"given":"Mark","family":"Teoh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simon","family":"Meagher","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabor","family":"Kovacs","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2003,10,7]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1479-828X.2001.tb01311.x"},{"key":"e_1_2_6_3_2","unstructured":"ESSURE.Training Manual L1660\u201301 Rev.
