Abdominal pregnancy is a rare subtype of ectopic pregnancy where conceptus is implanted in the peritoneal cavity other than uterus, fallopian tubes, ovaries or uterine ligaments.6 It is subdivided in to two groups based on Studdiford Criteria;7 a) primary abdominal pregnancy characterized by, i) normal fallopian tubes and ovaries with no evidence of recent or past pregnancy, ii) no evidence of uteroperitoneal fistula, iii) The pregnancy exclusively related to peritoneal surfaces; b) secondary abdominal pregnancy
in which there is evidence of tubal rupture or tubal abortion with secondary implantation.
Foetal bones were extruded from umblicus in this case and was a case of secondary abdominal pregnancy
. Incidence of ectopic pregnancies varies from place to place and it is more common in the area where there is more prevalence of STD's, genital tract TB and post abortal and puerperal sepsis.
Abdominal pregnancy occurs either as a result of tubal abortion or rupture (secondary abdominal pregnancy
) or rarely as a result of primary peritoneal implantation (primary abdominal pregnancy).
With a secondary abdominal pregnancy
or a broad-ligament heterotopic pregnancy in mind, it was decided to perform exploratory laparotomy.
