Abstract Background Retained products of conception (POC) following uterine evacuation can lead to adverse sequelae, including hemorrhage, endometritis, intrauterine adhesions, and reoperation. Use of procedural transvaginal sonography (TVUS) in the operating room has been proposed to help decrease retained POC. Methods A retrospective review of all first trimester uterine evacuation procedures from 1/2015 to 2/2017 was performed, noting use of transabdominal ultrasonography, retained products of conception, and complications. A practice change was implemented in May 2018, in which routine intra-procedural TVUS use was initiated. A second retrospective chart review was conducted to assess for post-implementation incidence of retained POC, re-operation, and associated complications. Results Prior to intra-procedural TVUS implementation, 130 eligible procedures were performed during the specified timeframe, with 9/130 (6.9%) incidence of retained products of conception. TAUS was performed in 59/130 (45.4%) of procedures, and 4/9 (44.4%) of those with retained products. There were eight re-operative procedures in seven patients, and two patients were treated with misoprostol. Complications included hemorrhage, Asherman’s syndrome and endometritis. Following implementation, 95 first trimester procedures were performed with transvaginal sonography, with 0 (0%) cases of retained POC (p = 0.01), no incidences of re-operation (p = 0.02), and one case of Asherman’s syndrome. TVUS findings led to additional focused suction curettage in 20/95 (21.0%) of procedures. The endometrium was measured on procedure completion in 64 procedures, with a mean thickness of 5.5 mm (1–12 mm). Conclusion Implementation of routine TVUS during uterine evacuation may reduce the incidence of retained POC and associated reoperation rates. Further multi-center trials are needed to confirm this finding.
