Is there a link between Spigelian and inguinal hernias? A case series

Area of Science:

• Abdominal Surgery
• Hernia Repair
• Surgical Case Series

Background:

• Spigelian hernias are rare ventral hernias, often difficult to diagnose due to asymptomatic presentation.
• Current literature typically addresses Spigelian and inguinal hernias independently.
• Understanding potential relationships between adjacent hernia types is clinically relevant.

Purpose of the Study:

• To investigate a potential association between Spigelian hernias and inguinal hernias.
• To analyze patient characteristics and outcomes in a series of Spigelian hernia repairs.
• To highlight a possible link between these two hernia types.

Main Methods:

• Retrospective case series of Spigelian hernias operated across five centers.
• Data collected from January 2021 to October 2023.
• Inclusion of patient demographics, surgical history, and operative outcomes.

Main Results:

• A total of 24 Spigelian hernias were analyzed.
• Fifteen cases (62.5%) demonstrated a connection to previous inguinal hernia surgery.
• The exact nature of this connection (pre-existing vs. secondary) remains undetermined.

Conclusions:

• A notable association exists between Spigelian and inguinal hernias.
• The genesis of this association requires further investigation.
• This series prompts consideration of concurrent or secondary development of Spigelian hernias in patients with inguinal hernia history.
