Procedure Overview
The surgical procedure for treating achalasia involves cutting the muscle of the lower esophageal sphincter to open the passage between the esophagus and stomach, making swallowing easier.
- The surgery is performed under general anesthesia and typically takes about 30 minutes, or up to an hour for repairs on both sides.
- Local anesthesia may be used postoperatively to manage pain.
- Antibiotics may be given during surgery to reduce infection risks.
Surgical Process
Laparoscopic (Keyhole) Surgery:
- The surgeon makes a small incision near the belly button and inserts an instrument to inflate the abdominal cavity with carbon dioxide.
- Several small cuts are made on the abdomen to insert surgical instruments through tubes (ports).
- A telescope is used to see inside the abdomen and perform the procedure.
- The muscle layers of the lower esophageal sphincter and lower esophagus are cut and spread apart, allowing the muscle to heal.
Additional Procedure (Fundoplication):
- To prevent acid reflux, the surgeon may wrap the top part of the stomach around the valve.
- This helps reduce the risk of stomach acid moving up into the esophagus.
What are the potential risks or complications of the procedure?
1. General Surgical Complications:
- Bleeding during or after the procedure, rarely requiring a blood transfusion.
- Hernia formation at the surgical site, which may require further surgery.
- Infection at the wound site, treatable with antibiotics but sometimes requiring special dressings.
- Venous thromboembolism (VTE) – Blood clots in the leg (DVT) or lungs (pulmonary embolism), which can be serious.
- Chest infections, particularly in smokers or those recovering from COVID-19.
- Adhesions (scar tissue) leading to bowel obstruction, possibly requiring another procedure.
- Allergic reactions to medications, materials, or dyes (rare but possible).
2. Keyhole Surgery Complications:
- Damage to internal structures (e.g., bowel, liver, blood vessels), which may require open surgery (risk: < 3 in 1,000).
- Surgical emphysema (trapped gas in the skin) or gas embolism (rare but serious).
- Conversion to open surgery if keyhole surgery is not possible.
3. Short Term Complications:
- Pneumothorax : Air escapes into the space around the lungs, sometimes requiring a chest drain.
- Perforation : A hole in the oesophagus or stomach (risk: 1 in 100) may require surgical repair and a longer hospital stay.
- Stitch Tear : If you vomit or strain in the first few weeks, the wrap may loosen, or a stomach hole may develop, requiring immediate surgery.
- Liver Damage : Moving the liver during surgery can cause injury (risk: 5 in 100), sometimes needing another operation.
- Spleen Damage : In rare cases, the spleen may need to be removed.
- Difficulty Swallowing : Temporary inflammation from the surgery may cause swallowing issues for a few months but typically resolves within three months.
4. Long Term Complications:
- Persistent Swallowing Difficulty : Some patients (risk: 5 in 100) may struggle to swallow certain foods like bread and meat.
- Incomplete Reflux Control : If the wrap loosens or is too loose, symptoms may persist but can often be managed with medication (risk: less than 5 in 100).
- Weight Loss : Feeling fuller than usual may cause temporary weight loss. Small, frequent meals can help maintain weight.
- Abdominal Discomfort and Bloating : Up to 3-5 in 10 people may experience gas buildup due to an inability to burp, leading to bloating and increased flatulence.
- Diarrhoea : A small number of patients (risk: less than 3 in 100) may experience loose stools, which can be managed with medication.
- Adhesions (Scar Tissue Formation) – Tissues may stick together abnormally, potentially causing bowel obstruction, though the risk is lower with keyhole surgery.
- Need for Additional Surgery – If severe symptoms persist beyond three months, another operation may be required (risk: less than 5 in 100).
While fundoplication is effective in treating reflux, some risks and long-term adjustments should be considered before undergoing the procedure.
Recovery After Surgery
1. Hospital Recovery:
- After the operation, patients are transferred to the recovery area and then to a ward.
- Anti-sickness medication is given.
- Drinking is allowed on the first day, followed by a soft diet.
- Acid-reducing medication is usually no longer needed.
- Most patients can go home the same day or the next, but some may need to stay longer based on their condition.
Warning Signs of Complications:Patients should watch for serious symptoms, including:
- Worsening pain with movement, breathing, or coughing.
- Fever or high temperature.
- Dizziness, fainting, or shortness of breath.
- Loss of appetite or worsening nausea after the first 1-2 days.
- Inability to pass stools or wind.
- Abdominal swelling.
- Difficulty urinating.
If any of these symptoms occur, immediate medical attention is required.
2. Returning to Normal Activities:
- Follow dietary instructions carefully to reduce the risk of complications. Start with a liquid diet, then transition to soft foods.
- Eat slowly and chew thoroughly.
- Avoid heavy lifting and manual work for a few weeks.
- Exercise is encouraged but should be resumed only with medical approval.
- Avoid driving until you can control your vehicle safely and check insurance requirements.
3. Long-Term Recovery:
- A full recovery is expected, with reflux symptoms significantly reduced or eliminated.
- A normal diet can usually be resumed after six weeks, but fizzy drinks should be avoided.
- Most patients return to work within a few weeks, depending on job type and individual recovery.
With proper care and adherence to medical advice, fundoplication provides lasting relief from acid reflux symptoms.
