To investigate the relationship between specimen extraction site choice and the development of incisional hernia (IH) at the extraction site after laparoscopic elective colorectal surgery for cancer.
Key Findings:
The overall incidence of IH was 30.9% for midline extraction sites and 0% for off-midline sites (p < 0.001), indicating a significant difference.
The risk for IH was 29-fold higher when midline was chosen as the extraction site compared to off-midline incisions.
Eight patients (7.1%) in the midline group required hernia repair, while none in the off-midline group did.
Interpretation:
The choice of midline extraction site significantly increases the risk of incisional hernia in patients undergoing laparoscopic colorectal surgery, suggesting a need for careful consideration of incision site during surgical planning to minimize IH risk.
Limitations:
The study was retrospective and may be subject to selection bias.
Exclusion of patients without follow-up CT scans may limit the generalizability of the findings.
Missing data may impact the robustness of the conclusions drawn.
Conclusion:
Midline extraction sites are associated with a higher incidence of incisional hernia compared to off-midline sites in laparoscopic colorectal surgery, indicating the need for surgical strategy adjustments to minimize IH risk.
