Ectopic pregnancy is a pregnancy that occurred outside the uterus,usually in the fallopian tube,followed by other abdominal *** pregnancy could not develop normally to term and requires sufficient evaluation and intervention with medication or surgery in most cases(1).As a rare form of abdominal pregnancy(2),splenic ectopic pregnancy could be treated by drug treatment(3)or surgical interventions,including laparotomy and laparoscopy,which focused on total splenectomy(4,5).A previous study(6)indicated that laparoscopic partial splenectomy for selected patients was safe and *** to the fragile texture of the spleen,the suture method during laparoscopic partial splenectomy was technically demanding since it might encounter higher risk of splenic vascular hemorrhage than total ***,few reports focused on the treatment of splenic ectopic pregnancy via laparoscopic partial splenectomy(7).In order to avoid the potential severe complications such as hemoperitoneum(8)caused by drug treatment alone,and to avert impaired hematopoietic and immune function caused by total splenectomy,we herein presented a case(Video 1)of a 30-year-old woman(gravida 2,para 1)undergoing laparoscopic partial splenectomy performed by hepatobiliary surgeons to treat splenic ectopic pregnancy.
