Summary
Incisional hernia risk after cesarean section is low, ranging from 0.0-5.6%. This systematic review found limited data on risk factors and incision types, highlighting the need for further research on C-section complications.
Area of Science:
- Surgical Complications
- Abdominal Surgery Outcomes
- Maternal Health Research
Background:
- Incisional hernia is a known complication of abdominal surgery.
- Cesarean section rates are increasing globally, with a median of 27% in Europe in 2015.
- The precise incidence of incisional hernia following cesarean sections remains uncertain.
Purpose of the Study:
- To systematically investigate the reported occurrence of incisional hernia after cesarean section.
- To analyze secondary outcomes including hernia repair frequency and differences based on incision type and urgency.
- To synthesize existing evidence on C-section related incisional hernia rates.
Main Methods:
- Systematic literature search of PubMed, Embase, and Cochrane Library.
- Inclusion of original studies with a minimum of ten patients and six-month follow-up.
- Analysis based on five eligible studies comprising 275,878 women, adhering to PRISMA guidelines.
Main Results:
- Incisional hernia occurrence post-cesarean section ranged from 0.0% to 5.6% across studies.
- Follow-up periods varied from six months to ten years.
- Limited data prevented analysis of risk factors, incision types, or urgency impact on hernia development.
Conclusions:
- The overall risk of incisional hernia following cesarean sections appears to be low.
- Current evidence is insufficient to determine differences based on incision type or urgency.
- Further well-designed studies are required to fully understand incisional hernia development after cesarean sections.
