After the screening step, we extracted the following data from the
eligible studies using a previous formatted data extraction sheet: (1)
Summary of the included studies including study design, sites and time,
participants and main inclusion criteria, total sample size, type of
laparoscopic surgery, type of traditional surgery, number of patients
assigned to each type, investigations, results, conclusion of each
study, (2) baseline characteristics of the patients in each study
including groups, Cases number in each group, age, gestational age
(days), number of symptomatic women at diagnosis, number of ruptured

interstitial pregnancy in recruited patients, (3) any repeated outcomes
(reported by two or more studies) including postoperative hospital stay
(days), operative time (minutes), blood loss (ml), post and

continuous outcomes were extracted as a mean and standard deviation and
dichotomous outcomes, events and total were extracted.
