Appendicectomy is associated with increased pregnancy rate: a cohort study

Area of Science:

• Reproductive health
• Surgical outcomes
• Gastrointestinal surgery

Background:

• The relationship between appendectomy, appendicitis, and subsequent fertility remains debated.
• Previous studies have yielded conflicting results regarding the impact of appendicitis and its surgical treatment on female fertility.

Purpose of the Study:

• To investigate the association between appendicitis and appendectomy with subsequent pregnancy rates.
• To determine if the severity of appendicitis influences fertility outcomes after appendectomy.

Main Methods:

• A cohort study utilized the Medicines Monitoring database, following women post-appendectomy and comparing them to controls.
• Pregnancy outcomes were tracked, and appendiceal pathology was manually verified.
• Cox regression models were employed to analyze the association between appendectomy, appendicitis, and pregnancy rates.

Main Results:

• Matched analyses (2935 appendectomy vs. 5870 controls) showed adjusted hazard ratios (HRs) for pregnancy of 1.20 (95% CI: 1.10-1.31).
• Unmatched analyses (3009 appendectomy vs. 122,912 controls) revealed higher adjusted HRs for pregnancy at 1.65 (95% CI: 1.55-1.75).
• Pregnancy rates varied by appendicitis severity: HRs were 0.98 for early stages, 0.72 for suppurative, and 0.64 for gangrenous appendicitis compared to normal appendix cases.

Conclusions:

• Appendectomy and early-stage appendicitis are associated with increased pregnancy rates.
• Early appendicitis in younger women is linked to better pregnancy outcomes compared to advanced appendicitis.
• Prompt diagnosis and surgical intervention (laparoscopy and appendectomy) are recommended for women of reproductive age.
