Recurrent Hernia of Anterior Abdominal Wall Clinical Trial
Official title:
Does Pregnancy Increase Risk of Ventral Hernia Recurrence?
The investigators will examine if pregnancy increases risk of ventral hernia recurrence
The investigators will establish a cohort of female fertile patients who underwent ventral
hernia repair (Umbilical, Epigastric and Incisional hernia repair) registered in the Danish
Hernia Database. The investigators will link these data at an individual level with the
Danish National Patient Registry (DNPR), Danish Medical Birth Registry (DMBR) and the Danish
Civil Registry (CPR).
From DMBR, subsequent pregnancies in the study cohort will be noted. From DNPR, ventral
hernia recurrence, defined as clinical recurrence and/or reoperation for recurrence will be
noted. Cases registered with both clinical recurrence and reoperation for recurrence, the
date of the earliest registration will be defined as the date of ventral hernia recurrence.
From CPR, date of death or emigration will be noted.
Through an extended Cox regression analysis, handling pregnancy as a time-dependent
variable, the investigators will examine whether pregnancy is associated with an increased
risk of ventral hernia recurrence.
