INTRODUCTION: Any pregnancy with implantation outside of the physiological site in the uterine cavity is called ectopic. Ectopic pregnancy presents in 0,25 – 1,4% of pregnancies and is considered to be a life-threatening condition. It is also the most common cause of maternal mortality in the first trimester. The most important methods of diagnosis are the transvaginal ultrasound and measuring the patient’s levels of β-hCG. Ectopic pregnancy can be treated with medicaments, surgically, or by expectant management. ----- OBJECTIVE: The aim of the study was to present the diagnostic parameters, treatment methods and duration of hospitalization of patients diagnosed with ectopic pregnancy at the University hospital "Sveti Duh" from 2009 to 2019 and to determine their relationship. ----- METHODS: Retrospective research has been conducted by gathering data from the hospital’s computer database. The data was then analyzed using the statistic program SPSS. ----- RESULTS: Data analysis gathered 268 patients hospitalized for ectopic at the University hospital Sveti Duh. Mean patients` age was 32,53. The most common diagnostic methods were utrasound which confirmed the diagnosis in 82% of the cases, and serial measurement of β-hCG, whose average value was 3171,40 IU/ml. Patients with the highest average levels of β-hCG (4439,77 IU/ml) were surgically treated, and those with the lowest levels (547,86 IU/ml) by expectant menagement. The most commonly used method was surgical treatment (63,8%) by laparoscopic salpingectomy, followed by medicament-based treatment using methotrexate (20,52%) and expectant management (15,67%). Only 3 cases (1,12% of fallopian tube rupture were noted. ----- CONCLUSION: Considering the fact that ectopic pregnancy is the most common cause of first trimester maternal mortality and is a life-threatening condition, early diagnosis and treatment is vital. A growing number of women being treated by expectant management and a diminishing number of fallopian tube ruptures indicate a positive trend of earlier diagnosis and treatment.
