ectopic pregnacy can be check by rectal palpation?upto what duration EP lasts(months)?
Outside United States
This is my earlier response:
Ectopic pregnancy in the cow is normally extra-uterine with attachment to viscera in the abdominal cavity. Embryonic and fetal deaths normally occur early to 3 months of the pregnancy. The dead embryo or fetus is retained in the abdominal cavity and not expelled to outside, like an abortion from the uterus. Diagnosis by rectal palpation is limited to the location in the abdominal cavity, which possibly can not be reached by hand. If reached by hand, the risk of death is not increased.
I refer you the article published at http://www.reproduction-online.org/content/131/4/631.full.
To further explain - diagnosis by rectal palpation is possible if the ectopic pregnancy is associated with the uterus and is in reach, and not associated with another organ which could make it out of reach. Duration of ectopic pregnancy is normally a few days, and is unusually a few weeks.
