Background: Ectopic pregnancy is the commonest acute abdominal emergency a gynaecologist face in his day to day practice. Ectopic pregnancy is a life–threatening condition accounts for 80% of maternal deaths that occur in early pregnancy. The aim of the study is to calculate incidence, the risk factors and the mode of clinical presentation of ectopic pregnancy.

Results: There were 40 cases of ectopic pregnancy. The most common symptom in our study was the lower abdominal pain in 100% cases whereas vaginal bleeding in 75% cases and amenorrhea in 80% cases. Fallopian tube was the commonest site of ectopic pregnancy and constitutes 95%, out of which ampulla part was the commonest site in fallopian tube which constitutes 42.11%.

Conclusions: In our study, the incidence of ectopic pregnancy is found to be 1/186. Over 45% cases fall in the age group of 21–25 years. We observed that pelvic inflammatory disease was the main risk factor. The classic triad of symptoms for an ectopic pregnancy that is abdominal pain, amenorrhoea, and vaginal bleeding was common in our study out of which pain abdomen of varying degree was present in 100% cases, amenorrhea in 80% and vaginal bleeding in 75% cases. Fallopian tube was the commonest site constitutes 95%, out of which ampulla part was the commonest site. The preferred surgical management was salpingectomy.
