A history of dilation and curettage (D&C) significantly increases the risk of cervical ectopic pregnancy (CEP). This finding highlights D&C as a strong risk factor for CEP compared to other pregnancy locations.
Area of Science:
- Obstetrics and Gynecology
- Reproductive Medicine
- Women's Health
Background:
- Cervical ectopic pregnancy (CEP) is a rare but potentially life-threatening condition.
- Identifying risk factors is crucial for early diagnosis and management.
Purpose of the Study:
- To evaluate risk factors associated with cervical ectopic pregnancies (CEP).
Main Methods:
- Retrospective, quasi-experimental case-control study (2000-2013).
- Compared 21 CEP cases with 126 controls (63 tubal ectopic pregnancies [TEP] and 63 intrauterine pregnancies [IUP]).
- Utilized binary logistic regression to analyze predictive factors.
Main Results:
- CEP patients showed a higher history of elective abortions, D&C, and cervical excisional procedures compared to IUP.
- CEP patients also had a higher history of D&C and cervical excisional procedures compared to TEP.
- Prior D&C significantly increased CEP risk versus IUP (aOR 1.4) and TEP (aOR 6.1).
Conclusions:
- Dilation and curettage (D&C) is identified as a significant risk factor for cervical ectopic pregnancy.
- Findings confirm previous associations between D&C and CEP.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
