Laparoscopic Cornuectomy as a Technique for Removal of Essure Microinserts.

STUDY OBJECTIVE: The authors present a laparoscopic technique for complete removal of Essure microinserts (including nitinol coil and positron emission tomography fibers). DESIGN: Step-wise instruction using video. The study was granted a Research Ethics Board exemption because the Regina Qu'Appelle Health Region Research Ethics Board does not require ethics board approval for single case submissions. SETTING: Tertiary care hospital. PATIENTS: Patient requesting removal of Essure inserts because of post-placement discomfort. INTERVENTIONS: Recent concern regarding adverse outcomes (persistent pelvic pain, device malposition, nickel allergy) after Essure placement has led to a small percentage of women requesting removal of the coils. Laparoscopic salpingectomy and salpingostomy have been successfully used for removal. Hysteroscopic removal has been achieved up to 6 weeks after placement; however, because of the fibrosis-inducing mechanism of the inserts, there is theoretical concern regarding fragmentation or incomplete removal with a cut and pull approach. MEASUREMENTS AND MAIN RESULTS: The authors used a laparoscopic surgical approach for removal of the Essure microinserts "en bloc" by performing a salpingectomy and mini-resection of the uterine cornua to the level of the endometrium. This approach ensures complete extraction of the Essure microinserts. The surgery was completed in a tertiary care hospital operating theatre with standard laparoscopic and electrosurgical instruments using a 10-mm infraumbilical port and two 5-mm ports in the left lower quadrant. CONCLUSION: En bloc resection of the fallopian tubes, uterine cornua, and Essure microinserts is a feasible laparoscopic approach to ensure complete removal of Essure microinserts. This approach is technically straightforward and can be achieved with minimal blood loss.

Does Essure Cause Significant De Novo Pain? A Retrospective Review of Indications for Second Surgeries After Essure Placement.

STUDY OBJECTIVES: To examine the surgical indications and pathologic findings in patients undergoing a second surgery after placement of the Essure permanent birth control system to determine the role of Essure in developing new-onset pelvic pain. DESIGN: Retrospective cohort (Canadian Task Force classification II-2). SETTING: Tertiary-level hospital. PATIENTS: Women who have had Essure placement and subsequent second surgery. INTERVENTION: Charts from women undergoing pelvic surgery after Essure placement from June 2002 to June 2013 were reviewed and the indication for the procedure, surgical and pathologic findings noted. MEASUREMENTS AND MAIN RESULTS: Of 1430 patients, 62 (4.3%) had a second surgery after Essure placement, and 24 of these (1.6%) had a surgical indication not related to pain. The remaining 38 patients (2.7%) had either new-onset (n = 27) or worsening pre-existing pain (n = 11). In the new-onset pain group, 15 (1%) had surgical findings or pathology consistent with a painful gynecologic condition. In the remaining 12, 8 (0.5%) seemed to be related to some perforation or migration of the Essure device. In 4 patients (0.3%) with no other obvious cause for the new-onset pain, it was thus attributed to the Essure microinsert. CONCLUSION: Essure sterilization can be associated with new-onset pain or a worsening of a pre-existing painful gynecologic condition, although both are very rare. A careful and complete consent before placement and a thorough examination if pain does occur usually show some etiology for the pain other than the Essure insert.
