Abstract
Background: Subxiphoid incisional hernias are one of the complications
following a median sternotomy, a surgical procedure to provide access to
the mediastinum. Incidence has been reported between 1-4%, although the
true incidence is not well known due to its asymptomatic nature. Method:
A comprehensive search was performed on multiple sites. Keywords
included “incisional hernia OR Subxiphoid hernia” AND “Median
sternotomy OR Cardiac Surgery OR Coronary artery bypass graft OR
Transplant OR Valve replacement”. Articles up to 1st of August 2020
were included in this study. Results: 8 articles were included in the
study, with a total number of 132 patient identified. The incidence
ranged from 0.81% to 3.44%. There was a mixture of repair method and
follow up period reported. Recurrence post-repair ranged from 10% to
43%. Conclusion: Subxiphoid incisional hernias remains challenging to
manage. We have discussed the incidence, risk factors, preventions, and
management of subxiphoid incisional hernias including both the open and
laparoscopic technique.
