Insights
Incisional hernia (IH) risk factors include higher BMI, prior laparotomy, and incisional infection. Lower serum albumin and elevated uric acid are key indicators. This research aids in identifying patients at risk for IH.
Area of Science:
- Abdominal surgery
- Hernia research
- Biochemical analysis
Background:
- Incisional hernia (IH) is a frequent complication following abdominal surgery.
- Predictive and preventive strategies for IH remain limited.
- Understanding risk factors, particularly biochemical markers, is crucial for patient management.
Purpose of the Study:
- To identify risk factors associated with the incidence of incisional hernias (IH).
- To investigate the correlation between blood test results and IH development.
- To provide evidence for better prediction and prevention of IH.
Main Methods:
- A case-control study involving 96 patients with IH and 192 controls who underwent midline laparotomy.
- Analysis of patient demographics, medical history, and pre-operative biochemical parameters.
- Multivariate logistic regression to determine independent risk factors for IH.
Main Results:
- Patients with IH had higher age, BMI, and history of hernia or laparotomy.
- Comorbidities like hypertension, diabetes, and incisional infection were more prevalent in the IH group.
- Significantly lower levels of hemoglobin, total protein, albumin, and HDL-C were observed in IH patients. Elevated UA, Lp(a), and ApoB/ApoA1 were identified as independent risk factors.
Conclusions:
- This study highlights the association between specific serum biochemical levels and IH incidence.
- Identified risk factors, including biochemical markers, can aid in perioperative risk assessment.
- The findings support the development of predictive models for IH to guide preventive strategies.
Purpose:
Incisional hernia (IH) is a common secondary ventral hernia after abdominal incisions and there is still little reliable evidence to predict and prevent IH. This study aimed to estimate risk factors of its incidence, especially concentrating on blood results.
Methods:
96 patients received midline laparotomy for gastrointestinal benign diseases and suffered from IH were enrolled in the IH group. A control group of 192 patients were randomly selected from patients underwent midline laparotomy for gastrointestinal benign diseases without IH.
Results:
Patients in the IH group exhibited higher age (P < 0.001), BMI (P < 0.001), hernia history (P = 0.001) and laparotomy history (P < 0.001). Rate of coronary heart disease (P = 0.046), hypertension (P < 0.001), diabetes (P = 0.008), incisional infection (P = 0.004) and emergency surgery (P = 0.041) were also higher in the IH group. Patients with IH had lower levels of Hb (P = 0.002), TP (P = 0.013), ALB (P < 0.001), A/G (P = 0.019), PA (P < 0.001), HDL-C (P = 0.008) and ApoA1 (P = 0.005). Meanwhile, patients in the control group bore lower levels of LDH (P = 0.008), GLU (P = 0.007), BUN (P = 0.048), UA (P = 0.021), TG (P = 0.011), TG/HDL-C (P = 0.002), TC/HDL-C (P = 0.013), ApoB/ApoA1 (P = 0.001) and Lp(a) (P = 0.001). A multivariate logistic regression revealed that high BMI, laparotomy history, incisional infection, decreased PA, elevated levels of UA, Lp(a) and ApoB/ApoA1 were independent risk factors of IH.
Conclusion:
This is the first study to reveal the relationship between IH and serum biochemical levels, and give a prediction through the nomograph model. These results will help surgeons identify high-risk patients, and take measures to prevent IH during the perioperative period.
