What is an Abdominal Hernia?
An abdominal hernia is a condition where internal organs (usually intestines) protrude outward through a weak point or tear in the abdominal wall. The term "hernia," meaning "rupture" in Latin, describes one of the most common surgical diseases worldwide. These openings, resulting from weakened abdominal wall muscles or congenital defects, can enlarge over time and lead to serious health problems.
Types and Locations of Abdominal Hernias
1. Inguinal Hernia
It is 8-10 times more common in men than in women. It is divided into indirect and direct inguinal hernias, originating from a weakness in the inguinal canal.
2. Femoral Hernia
Seen more frequently in women and the elderly. It occurs in the femoral canal region and often carries a risk of strangulation requiring emergency surgery.
3. Umbilical Hernia
Occurs around the navel. While common in newborns, it can appear in adults in conditions that increase intra-abdominal pressure (pregnancy, obesity, chronic cough).
4. Epigastric Hernia
Occurs in the midline of the abdomen (linea alba), above the navel. Usually small in size but pain complaints are significant.
5. Spigelian Hernia
A rare type of hernia occurring at the lateral edge of the abdominal muscles. Diagnosis can be difficult and is often confirmed by ultrasound or tomography.
6. Incisional Hernia
Develops at the incision site following previous abdominal surgery. Postoperative infection, obesity and smoking are risk factors.
Causes and Risk Factors
Anatomical Factors
- Congenital weakness of the inguinal canal
- Connective tissue diseases
- Age-related weakening of muscles and fascia
Acquired Factors
- Chronic cough (COPD, smoking)
- Chronic constipation and straining
- Heavy lifting
- Difficulty urinating due to prostate enlargement
- Pregnancy and childbirth
- Obesity
- Tumors that increase intra-abdominal pressure
- Previous abdominal surgeries
Symptoms and Diagnostic Methods
Common Symptoms
- Swelling in the abdomen or groin (especially prominent when standing or straining)
- Pain or discomfort in the swelling area
- Reduction of the swelling when pushed inward
- Burning or heaviness sensation in the groin
- Rarely nausea and vomiting (in case of strangulated hernia)
Dangerous Symptoms (Emergency)
- Sudden onset of severe pain
- Swelling becoming red and tender
- Swelling not being reducible
- Nausea, vomiting, abdominal distension
- Inability to pass gas or stool
Diagnostic Methods
- Physical Examination: Performed in standing and lying positions
- Ultrasonography: Especially for diagnosing small hernias
- Computed Tomography (CT): For complicated hernias and pre-surgical planning
- Magnetic Resonance Imaging (MRI): For sports hernias and atypical cases
Complications
1. Strangulated Hernia
Compression of organs within the hernia sac and impairment of blood flow. A life-threatening condition requiring emergency surgery. If surgical intervention is not performed within 6-8 hours, intestinal necrosis may develop.
2. Obstruction
Cessation of intestinal passage due to blockage of the intestinal segment within the hernia sac.
3. Incarceration
Inability to reduce the hernia contents back into the abdominal cavity.
4. Chronic Pain
Chronic groin pain that develops in untreated hernias.
Treatment Methods
Non-Surgical Approaches
- Use of a hernia truss (temporary solution)
- Weight loss
- Constipation prevention
- Avoiding heavy lifting
- Smoking cessation
Note: Non-surgical methods do not cure the hernia; they only alleviate symptoms and slow progression.
Surgical Treatment
1. Open Hernia Repair
- Traditional Repair: Closing the defect with sutures only
- Mesh Repair: Reinforced repair using a synthetic mesh
Advantages: Can be performed under local anesthesia, lower cost, preferred for large and complicated hernias.
Disadvantages: Larger incision, longer recovery time, more prominent scar tissue.
2. Laparoscopic (Minimally Invasive) Repair
Transabdominal Preperitoneal (TAPP): Approach from within the abdomen, anterior to the peritoneum.
Totally Extraperitoneal (TEP): Completely extraperitoneal approach.
Advantages: Smaller incisions, less pain, faster recovery, earlier return to normal activity, lower infection risk.
Disadvantages: Requires general anesthesia, special equipment and expertise; may not suit some complicated hernias.
Postoperative Recovery
First 48 hours: Light activity and walking, pain medication, wound care.
First week: Light household chores, no driving, no lifting over 5 kg.
2-4 weeks: Return to office work, light exercise.
6-8 weeks: Return to heavy sports and labour, complete recovery.
Reducing the Risk of Recurrence
- Appropriate Surgical Technique: Repair by an experienced surgeon using the right method.
- Use of Mesh: The literature reports markedly lower recurrence rates compared with suture-only repair.
- Control of Risk Factors: Smoking cessation, weight control, treatment of chronic cough, constipation prevention.
- Postoperative Care: Adherence to the surgeon's recommendations.
Frequently Asked Questions
When is hernia surgery mandatory?
Hernias with a risk of strangulation, rapidly growing, or causing severe pain require urgent surgery.
Is hernia surgery risky?
In experienced hands it is a low-risk operation. The literature reports low complication rates; individual risk depends on the patient's general condition and the type of hernia.
Does hernia recur after surgery?
With modern mesh repair techniques, recurrence rates reported in the literature are low. Smoking, obesity and chronic cough increase the likelihood of recurrence.
Does exercising cause hernias?
Exercise performed with proper technique does not pose a risk. Sudden straining and heavy lifting are risk factors.
Important Warnings
- Do not use a hernia truss on your own.
- Do not try to forcefully push the swelling inward.
- In case of emergency symptoms, seek hospital care without delay.
- Do not postpone the surgery decision; hernias do not heal on their own.
Conclusion
Abdominal hernias respond well to treatment when addressed at the right time with an appropriate technique. Early diagnosis and treatment are critical in preventing serious complications. If you suspect a hernia, consult a general surgeon for a detailed examination.
