Recurrent hernia

Disease Name Evaluation

• Disease name: Recurrent hernia (Recurrent hernia) — This is a medically valid term. It refers to a condition in which a hernia develops again at a site that previously underwent repair.

1. Disease Description (Causes and Symptoms)

• Cause and pathophysiology: At a previous hernia surgery site (especially a scar/incisional hernia caused by open surgery), the sutured area or weakened abdominal wall opens again, allowing organs or abdominal contents to protrude outside the abdominal wall. Excessive tension at the suture site, tissue weakness, vulnerability of scar tissue, or failure or infection of the mesh can cause recurrence.
• Major risk factors: Older age, obesity, smoking, chronic cough (lung disease), constipation (straining during bowel movements), pregnancy, diabetes, poor nutrition or weakened immunity, and a history of abdominal surgery (incisional hernia).
• Main symptoms: A bulging lump in the abdomen during activity or coughing (hernia protrusion), pain or discomfort in the area, and a feeling of abdominal distension. Rarely, if the hernia contents become trapped (incarceration), severe localized pain, abdominal distension, vomiting, difficulty passing stool or gas (symptoms of intestinal obstruction), and systemic fever or weakness (if it progresses to necrosis or sepsis) may occur.

2. Treatment Methods and Precautions

• Standard treatment
  • If there are no symptoms or symptoms are mild, observation may be possible; however, surgical repair is recommended for most recurrent hernias.
  • Tension-free mesh repair is standard: a method of reinforcing the abdominal wall with mesh (onlay, sublay, intraperitoneal/IPOM, etc.). Recently, laparoscopic (extraperitoneal) approaches (e.g., TEP/TAE and IPOM) have also been widely used.
  • The reoperation strategy varies depending on the previous surgical method (if the previous surgery was open, a laparoscopic approach may be considered; if the previous surgery was laparoscopic, an open approach may be considered).
  • If the wound is contaminated or infection is suspected, an individualized approach such as biologic mesh or temporary suturing is required.
  • Emergency situations (suspected incarceration, strangulation, intestinal obstruction, or necrosis): Immediate emergency surgery (including possible bowel resection) is required.
• Medication/supportive treatment
  • Pain control, antibiotics (in cases of infection), and electrolyte or fluid replacement (in cases of intestinal obstruction or vomiting).
  • Before and after surgery: Constipation treatments (suppositories/laxatives), cough control (antitussives), smoking cessation, and weight loss are recommended.
• Postoperative precautions (self-care)
  • Initially, avoid lifting heavy objects and excessive straining, prevent severe coughing (use antitussives if necessary), and consider wearing an abdominal binder (follow the doctor's instructions).
  • Seek medical attention immediately if signs of wound infection (redness, pus, or fever) occur.
• Complications
  • Re-recurrence, surgical-site infection, chronic pain (nerve damage), bowel injury, intestinal obstruction, enterocutaneous fistula, and mesh-related complications (infection, migration, or adhesions).
• Prognosis
  • Appropriate mesh repair and management of risk factors (such as weight loss and smoking cessation) greatly reduce the recurrence rate. Incisional hernias have a relatively high recurrence rate by nature.

3. Outpatient Visit Checklist (Including Items to Bring and Example Questions)

• Items to bring (helpful for the consultation)
  • List of medications currently being taken (especially anticoagulants, antiplatelet agents, immunosuppressants, steroids, etc.)
  • Previous surgical records (if possible, previous operative records, dates of surgery, operative notes, or the hospital name)
  • Recent imaging results (abdominal CT or ultrasound), if available
  • Symptom diary: Pattern of protrusion (when it appears), intensity and frequency of pain, episodes suggesting incarceration (does not return to its position), and changes in bowel movements or abdominal symptoms
  • List of underlying diseases (diabetes, COPD, etc.) and smoking and alcohol-use history
• Items to check and measure during the outpatient visit
  • Size and reducibility of the hernia (whether it goes back in when lying down), skin condition (redness, necrosis, or inflammation), and general condition (fever or vomiting)
• Example questions to ask at the outpatient visit (patient → doctor)
  • "Does this hernia require surgery right away, or can we observe it?"
  • "Which surgical method do you recommend, and what are its advantages and disadvantages?"
  • "What preparations do I need before and after surgery (stopping medications, fasting, smoking cessation, etc.)?"

4. Examples of General Questions to Ask the Doctor

• What are the criteria for recommending surgery (symptoms, size, risk factors, etc.)?
• How will my underlying conditions (e.g., diabetes or lung disease) affect the surgical outcome?
• What is the risk of postoperative complications and recurrence?
• How long should I take off work before and after surgery, and when can I start lifting heavy objects?
• What should I do if incarceration (a condition in which the hernia cannot be pushed back) is suspected?

5. Examples of Condition-Specific Questions (Specific to Recurrent Hernia)

• "Depending on how I was previously operated on (open/laparoscopic, with or without mesh), what reoperation method is recommended?"
• "If the hernia recurred even though mesh was already used, does the existing mesh need to be removed during reoperation, or would additional reinforcement with new mesh be sufficient?"

Additional Reference (Clinical Points)

• Emergency symptoms (requiring an immediate visit to the emergency room): Sudden severe localized pain, a hernia area that is hard and cannot be pushed back, persistent vomiting, abdominal distension, fever, etc.
• Lifestyle management to reduce the risk of recurrence: Weight loss, smoking cessation, treatment of chronic cough and constipation, and compliance with activity restrictions according to the doctor's instructions after surgery.
