Esophageal Surgery

Gastroesophageal Reflux Disease (GERD)

Surgical treatment for severe GERD when medication fails to control symptoms or complications arise.

Indications for surgery:

• Persistent symptoms despite medical management
• Large hiatal hernia with reflux
• Barrett’s esophagus
• Medication intolerance or side effects
• Patient preference for definitive treatment

Surgical procedures:

• Laparoscopic Nissen fundoplication (360-degree wrap)
• Toupet fundoplication (270-degree wrap)
• Hiatal hernia repair with mesh reinforcement
• Paraesophageal hernia repair
• LINX magnetic sphincter augmentation

Benefits of surgery:
Over 90% of patients experience significant symptom improvement and can discontinue acid-suppressing medications after successful fundoplication.

Achalasia

Achalasia is a motility disorder where the lower esophageal sphincter fails to relax, causing difficulty swallowing.

Treatment options:

• Laparoscopic Heller myotomy with partial fundoplication
• Peroral endoscopic myotomy (POEM)
• Pneumatic dilation (for selected cases)
• Botulinum toxin injection (temporary relief)

Surgical approach:
Laparoscopic Heller myotomy with Dor fundoplication is the gold standard, providing excellent long-term relief of dysphagia while minimizing reflux complications.

Hiatal Hernia

Hiatal hernias occur when part of the stomach pushes through the diaphragm into the chest cavity.

Types treated:

• Sliding hiatal hernia (Type I)
• Paraesophageal hernia (Type II, III, IV)
• Giant hiatal hernia

Surgical repair:

• Laparoscopic hiatal hernia repair
• Reduction of herniated stomach
• Crural repair with mesh reinforcement
• Fundoplication to prevent reflux
• Emergency repair for incarcerated hernias

Large paraesophageal hernias can cause gastric volvulus and require prompt surgical attention to prevent life-threatening complications.

Gastric (Stomach) Surgery

Frequently Asked Questions

How long does recovery take after major GI surgery?

Recovery time varies significantly by procedure. Minor laparoscopic procedures like fundoplication typically require 1-2 weeks before returning to normal activities. Major procedures like gastrectomy usually require 4-6 weeks, while complex operations like the Whipple procedure may require 6-8 weeks for full recovery. Individual factors including age, overall health, and complications also affect recovery time.

Can GERD be treated with surgery?

Yes, laparoscopic fundoplication is highly effective for GERD, especially when medical management with proton pump inhibitors fails or patients develop complications like Barrett’s esophagus. Over 90% of patients experience significant symptom improvement and can discontinue acid-suppressing medications after successful surgery. The procedure involves wrapping the top of the stomach around the lower esophagus to strengthen the valve and prevent reflux.

What is the Whipple procedure?

The Whipple procedure (pancreaticoduodenectomy) is a complex operation that removes the head of the pancreas, duodenum, gallbladder, part of the bile duct, and sometimes part of the stomach. It’s performed primarily for pancreatic head tumors, ampullary cancer, and distal bile duct cancer. The operation involves complex reconstruction with three separate connections (anastomoses). It requires specialized expertise and is best performed at high-volume centers with experienced surgical teams.

Is laparoscopic surgery available for stomach cancer?

Yes, laparoscopic gastrectomy is increasingly performed for early-stage gastric cancer. Studies show that minimally invasive approaches offer faster recovery, less pain, and shorter hospital stays while achieving the same oncological outcomes as open surgery. For advanced gastric cancer, open surgery may still be preferred to ensure complete tumor removal and adequate lymph node dissection. Your surgeon will discuss the best approach based on tumor stage, location, and individual factors.

How successful is surgery for pancreatic cancer?

Surgery offers the only chance for cure in pancreatic cancer, but success depends heavily on disease stage. For resectable tumors (about 20% of cases), the Whipple procedure combined with chemotherapy provides 5-year survival rates of 20-30%. Unfortunately, most pancreatic cancers are diagnosed at advanced stages when cure is not possible. Even in these cases, palliative surgery can significantly improve quality of life by relieving jaundice and preventing bowel obstruction.

What are the risks of esophageal surgery?

Esophagectomy is a major operation with potential complications including anastomotic leak (5-10%), pneumonia, atrial fibrillation, chylothorax, and vocal cord injury. Minimally invasive techniques have reduced complication rates compared to traditional open surgery. We take extensive precautions including careful patient selection, optimization of nutrition and lung function before surgery, and meticulous surgical technique to minimize risks. Most patients do well with appropriate perioperative care.

Can achalasia be treated without surgery?

Achalasia can be temporarily managed with botulinum toxin injections or pneumatic dilation, but these treatments often need to be repeated. Laparoscopic Heller myotomy with partial fundoplication provides the most durable long-term relief, with over 90% of patients experiencing significant improvement in swallowing that lasts for many years. The minimally invasive approach allows faster recovery with excellent results.

Do I need my spleen removed with pancreatic surgery?

For tumors in the pancreatic body or tail, distal pancreatectomy traditionally includes splenectomy (spleen removal) because of shared blood supply. However, spleen-preserving techniques are possible in selected cases, particularly for benign tumors. Removing the spleen requires vaccination against certain bacteria before or after surgery. Your surgeon will discuss whether spleen preservation is feasible in your case.
