Abstract Objective: Providing a systematic review of type 2 articles published at the time we began our review up cervical dysgenesis (CD) by taking into consideration from inception to July 2019. an interesting and rare case of genital anomaly which was treated with the use of laparoscopic ultrasound Results: Three hundred thirty-four articles were guidance. identified, three hundred fifteen other articles were excluded for various reasons. Overall, nineteen articles Materials and Methods: A research of MEDLINE, were incorporated for further assessment. Three surgical EMBASE, Web of Sciences, Scopus, ClinicalTrial.gov, techniques were used to treat type 2 cervical dysgenesis: OVID and Cochrane Library was done. We analysed all drilling and coring technique (CDT), utero-vaginal types of study including case reports. We identified anastomosis (UVA) and hysterectomy (HRT) or hemi- hysterectomy (H-HRT). Recurrences (38%) were Obstetrics and Gynecology Research - Vol. 3 No. 2 – June 2020. 119 Obstet Gynecol Res 2020; 3 (2): 119-131 DOI: 10.26502/ogr036 described only with CDT. Five successful pregnancies it generally affects women during their childbearing were reported with the same technique. age, impairing fertility [2]. In the new ESHRE/ESGE classification, cervical anomaly is classified into 5 Conclusions: Type 2 cervical dysgenesis is a rare groups or classes: C0 (normal cervix), C1 (septate congenital malformation. Data about recurrence and cervix), C2 (double normal cervix), C3 (unilateral pregnancy rate are too sparse to recommend one cervical aplasia), and C4 (cervical aplasia) [3]. In technique rather than another.
