Gasless laparoendoscopic single-site surgery with intraoperative autologous blood transfusion for management of ectopic pregnancy with significant hemoperitoneum: a retrospective observational study

Background With advances in diagnostic and therapeutic modalities, earlier detection of ectopic pregnancy with minimal symptoms makes laparoscopic management more common. However, if diagnostic delay occurs, significant hemoperitoneum associated with ectopic pregnancy is still a potentially life-threatening condition, which presents a therapeutic challenge especially when minimally invasive surgical approach is a significant concern. Herein, retrospective observational study in 18 consecutive cases of ectopic pregnancy with significant hemoperitoneum ≥ 800 mL was performed to assess the feasibility and efficacy of gasless laparoendoscopic single-site (LESS) surgery with intraoperative autologous blood cell salvage and donation for management.
