Emergent Hysteroscopic Removal of Retained Products of Conception Following Laparoscopic Temporary Uterine Artery Ligation

Here, we describe two cases of retained products of conception (RPOC) that were successfully managed with hysteroscopic resection after laparoscopic temporary uterine artery ligation. Both patients were diagnosed with RPOC after early miscarriages. Case 1 was urgently admitted due to massive bleeding and underwent surgery following a blood transfusion. After laparoscopic temporary bilateral uterine artery ligation, the mass was hysteroscopically removed, and the ligation was subsequently released. The patient subsequently achieved an ongoing pregnancy. Case 2 underwent semi-emergency surgery due to intermittent bleeding. Initially, hysteroscopic surgery was planned. However, bleeding resulted in poor visualization of the operative field, and laparoscopic surgery was performed. In many previous reports of RPOC with heavy bleeding, uterine artery embolization was performed. However, there are concerns regarding the effect of a long-term reduction in uterine blood flow on fertility. Our method is not expected to decrease fertility because the ischemic effect is very short.
