Ectopic pregnancy is an early pregnancy complication in which a fertilized ovum implant outside the uterine cavity. Implantation may occur anywhere along the reproductive tract with the most common implantation site being the fallopian tube. The incidence of ectopic pregnancy is 1% of pregnant women, and may seriously compromise women's health and future fertility.

Currently, ectopic pregnancy can be often diagnosed before the woman's condition has deteriorated, which has altered the former clinical picture of a lifethreatening disease into a more benign condition in frequently asymptomatic women.

Inclusion criteria:

• RCTs and observational studies
• All types of ectopic pregnancies.
• All types of treatments and medications for ectopic pregnancies.
• The long-term survival of patients with or without complications.
• Successful pregnancy and birth.

Exclusion criteria:

• Articles of failed treatments of ectopic pregnancies.
• Articles with over all P value > 0.05.
• Articles for which the full text is not available in English.

Sample size: All articles fulfilling the inclusion criteria within the last five years.

Study tools: Primary data will be re-analyzed statistically and processed data to be compared. Secondary data will be analyzed for correlation between the type of anastomosis (hand sewing vs. staplers) and between measurements outcome (leakage and, stricture and fistula formation).

• Study procedure: The study will start by searching articles using the key words and then downloading papers that fulfill the inclusion criteria and excluding papers with exclusion criteria. These papers will be examined by the supervisors to make sure of finding the appropriate source of data and then I will start working with the statistical supervisor and put data on R-based software for meta-analysis and start conducting the study.
