A number of risk factors for incisional hernia have been identified, but the pathogenesis remains unclear.
Variables predictive for incisional hernia were assessed by multiple regression analysis.
|Smokers had a 4-fold higher risk of incisional hernia independent of other risk factors and confounders. |

The team included all 916 patients undergoing laparotomy from 1997 through 1998.
Clinical examinations in 310 patients were performed by surgeons.
The investigators excluded patients who failed to meet for examination, died, or were lost to follow-up.
The researchers looked at 34 variables related to patient history, preoperative clinical condition, operative severity and findings, and the surgeon’s training.
The team noted that the incidence of incisional hernia was 26%.
The investigators observed that smokers had a 4-fold higher risk of incisional hernia independent of other risk factors and confounders.
In addition, the researchers identified relaparotomy as the strongest factor associated with hernia.
Other ther risk factors were postoperative wound complications, age, and male sex.
Dr Sørensen concluded that, “Smoking is a significant risk factor for incisional hernia in line with relaparotomy, postoperative wound complications, older age, and male sex.”
