Surgical versus medical methods for second trimester induced abortion

Area of Science:

• Reproductive Health
• Surgical Procedures
• Medical Interventions

Background:

• Second-trimester abortions represent a significant portion of abortion-related morbidity and mortality.
• Optimal methods for second-trimester abortion are crucial for patient safety.

Purpose of the Study:

• To compare the efficacy, side effects, adverse events, and acceptability of surgical versus medical abortion methods in the second trimester.
• To identify the safest and most effective approach for second-trimester pregnancy termination.

Main Methods:

• Systematic review of randomized trials comparing surgical and medical second-trimester abortion methods (gestation >/= 13 weeks).
• Searched multiple databases (PubMed, EMBASE, POPLINE, CENTRAL) and reference lists.
• Assessed study validity using Cochrane Handbook methods; data abstracted by two reviewers.

Main Results:

• Dilation and evacuation (D&E) demonstrated a lower incidence of minor complications compared to prostaglandin instillation.
• D&E also showed fewer total minor and major complications and fewer adverse events than mifepristone and misoprostol.
• While mifepristone and misoprostol caused more pain, efficacy and acceptability were comparable between methods; D&E required less hospitalization.

Conclusions:

• Dilation and evacuation (D&E) is a superior method to prostaglandin instillation for second-trimester abortion.
• Current evidence suggests D&E is also favored over mifepristone and misoprostol, warranting larger randomized trials for confirmation.
