Methotrexate therapy followed by laparotomy to manage a viable first-trimester cesarean scar ectopic pregnancy in a low-resource setting: A case report.

Cesarean scar ectopic pregnancy (CSEP) is rare, occurring in 1:1800 to 1:2625 pregnancies. It is classified into two types: endogenous, which grows inside the uterine cavity; and exogenous, which grows outward, toward the bladder. Both types are associated with increased maternal morbidity and mortality.
