Background/Aim:
Umbilical defunctioning ileostomy (UDI) spares one incision, which may reduce the overall incidence of incisional hernia. Our aim was to evaluate the occurrence and risk factors of incisional hernias between UDI and conventional defunctioning ileostomy (CDI) after ileostomy closure.
Patients And Methods:
Incidence of incisional hernia after ileostomy closure was compared between UDI (n=51) and CDI (n=86) groups. Risk factors for incisional hernia were also considered through a retrospective analysis.
Results:
The overall incidence of incisional hernia was 5.9% in the UDI group, which was significantly lower than the 22.1% (7.0% at the midline incision and 15.1% at the stoma site) in the CDI group (p=0.012). Multivariate analysis showed higher BMI (p=0.035) and CDI (p=0.031) as risk factors for developing incisional hernias overall.
Conclusion:
UDI results in fewer incisional hernias than CDI and seems to be superior to CDI from the standpoint of overall incidence of incisional hernias.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
