From the Guidelines
The primary risk factors for inguinal hernia in a 70-year-old smoker include advanced age, smoking history, and potential comorbidities that may increase the risk of surgical site infections (SSI), which are also a risk factor for incisional hernia. Age is significant because tissue weakens over time, with collagen becoming less elastic and more prone to herniation. Smoking directly contributes by causing chronic coughing, which increases intra-abdominal pressure, and by impairing tissue healing through decreased blood flow and oxygen delivery, as noted in the context of surgical site infections 1.
Key Risk Factors
- Advanced age: Tissue weakening over time increases the risk of herniation
- Smoking history: Chronic coughing and impaired tissue healing contribute to hernia risk
- Potential comorbidities: Conditions that may increase the risk of SSI, which is a risk factor for incisional hernia, as mentioned in the study on intraoperative surgical site infection control and prevention 1
- Male gender: Anatomical differences make men more likely to develop inguinal hernias
- Other contributing factors: Chronic constipation, prostate enlargement, heavy lifting, and family history of hernias
Recommendations
For this patient, smoking cessation is strongly recommended to reduce coughing and improve tissue integrity. Weight management, avoiding heavy lifting, treating constipation with fiber and adequate hydration, and managing any prostate issues would also be beneficial preventive measures. If the patient already has symptoms of a hernia (groin bulge, pain with exertion), prompt medical evaluation is necessary as hernias typically require surgical repair, especially in elderly patients where complications like incarceration or strangulation are more common. The study on intraoperative surgical site infection control and prevention highlights the importance of considering the risk of SSI in surgical patients, which is relevant to the management of inguinal hernias 1.
From the Research
Risk Factors for Inguinal Hernia in a 70-year-old Smoker
- Age: Being 70 years old is a risk factor for inguinal hernia, as the risk of developing an inguinal hernia increases with age 2, 3.
- Smoking status: Smoking has been shown to be a risk factor for inguinal hernia repair outcomes, with current smokers having higher rates of recurrence, surgical site occurrences, and surgical site infections compared to non-smokers 4, 2, 3.
- Hernia characteristics: The type and size of the hernia may also affect the risk of complications, with larger hernias being more likely to recur 2, 3.
- Operative characteristics: The type of surgical approach used, such as open or laparoscopic, may also affect the risk of complications, with laparoscopic approaches being associated with lower rates of recurrence and surgical site infections 4, 3.
- Comorbidities: The presence of comorbidities, such as chronic obstructive pulmonary disease (COPD), may also affect the risk of complications, with smokers being more likely to have COPD 5.
Impact of Smoking on Inguinal Hernia Repair Outcomes
- Recurrence: Smoking has been shown to be associated with a higher risk of recurrence after inguinal hernia repair, with a meta-analysis finding a three-fold increase in recurrence rates among smokers 2.
- Surgical site occurrences: Smoking has also been shown to be associated with a higher risk of surgical site occurrences, including surgical site infections and seroma, after inguinal hernia repair 4, 3.
- Postoperative complications: Smoking has been shown to be associated with a higher risk of postoperative complications, including pneumonia and return to the operating room, after inguinal hernia repair 4.
Clinical Relevance of Smoking Cessation
- While smoking has been shown to be associated with a higher risk of complications after inguinal hernia repair, the clinical relevance of smoking cessation is unclear, with some studies suggesting that smoking cessation may not be necessary to prevent short-term adverse outcomes 6, 5, 3.
- Further studies are needed to evaluate the impact of preoperative smoking cessation on reducing recurrence and other complications after inguinal hernia repair 2, 3.
