Peritoneal reimplantation of trophoblastic tissue following laparoscopic treatment of ectopic pregnancy: A case report and review of literature.

Reimplantation of trophoblastic tissue in the abdomen after treatment of an ectopic pregnancy is rarely reported but is very likely an underestimated complication to laparoscopy. We present a case report and review of the literature. A total of 25 cases of reimplantation of trophoblastic tissue following laparoscopic removal of ectopic pregnancy (EP) have been reported in the period January 1989 to January 2018 including our case. No cases have been reported before 1989. The use of salpingostomy vs. salpingectomy as the primary treatment of EP prior to the complication is comparable. In approximately half of the cases the reimplanted trophoblastic tissue was placed in the peritoneum and the rest in the omentum, on the bowel, in the uterosacral ligament and on the uterine body. During surgery it is important to remove all pathologic tissue and the Trendelenburg position should be considered avoided. Treatment using a single-dose Methotrexate should be performed when there is a potential risk of retaining tissue or if the serum human chorionic gonadotropin (S-hCG) is insufficiently decreasing after surgery. All patients treated for an ectopic pregnancy should be considered monitored until S-hCG is undetectable.
