Gastric Cancer Surgery

Gastric cancer surgery is the cornerstone of treatment for patients with resectable stomach cancer. The primary goal of surgery is to completely remove the tumor along with the surrounding lymph nodes while preserving digestive function whenever possible. Advances in surgical techniques, including laparoscopic and robotic-assisted gastrectomy, have improved surgical precision, reduced postoperative pain, shortened hospital stays, and accelerated recovery without compromising oncological outcomes. Successful treatment depends on early diagnosis, accurate staging, and a multidisciplinary treatment approach involving general surgeons, medical oncologists, gastroenterologists, radiologists, pathologists, and nutrition specialists.

What is Stomach Cancer?

Stomach cancer, also known as gastric cancer, develops when abnormal cells grow uncontrollably in the lining of the stomach. It is one of the most common gastrointestinal cancers worldwide.

Although early-stage stomach cancer may cause few or no symptoms, early diagnosis significantly improves treatment options and survival rates.

When is Gastric Cancer Surgery Recommended?

Surgery is the primary treatment for patients with localized stomach cancer.

It may also be recommended for:

• Early-stage gastric cancer.

• Locally advanced stomach cancer following chemotherapy.

• Selected patients with limited metastatic disease as part of a comprehensive treatment strategy.

• Certain non-cancerous stomach tumors with malignant potential.

Treatment recommendations depend on the stage of the disease, tumor location, and the patient's overall health.

Signs and Symptoms

Symptoms may include:

• Persistent upper abdominal pain or discomfort.

• Feeling full after eating small amounts of food.

• Unexplained weight loss.

• Loss of appetite.

• Nausea or vomiting.

• Difficulty swallowing, particularly for tumors near the upper stomach.

• Fatigue caused by anemia.

• Black stools or gastrointestinal bleeding in advanced cases.

Because symptoms are often nonspecific, early medical evaluation is essential.

Risk Factors

Several factors increase the risk of stomach cancer, including:

• Helicobacter pylori (H. pylori) infection.

• Smoking.

• Diets high in smoked, salted, or processed foods.

• Family history of gastric cancer.

• Chronic gastritis.

• Previous stomach surgery.

• Certain hereditary cancer syndromes.

How is Stomach Cancer Diagnosed?

Diagnosis typically includes:

• Medical history and physical examination.

• Upper gastrointestinal endoscopy (Gastroscopy) with biopsy.

• Histopathological examination of biopsy samples.

• CT scan to determine the extent of disease.

• Endoscopic ultrasound (EUS) in selected patients.

• PET-CT in selected cases.

• Blood tests and nutritional assessment.

How is Gastric Cancer Surgery Performed?

The surgeon removes the tumor together with an appropriate margin of healthy tissue and performs D2 lymph node dissection, which is considered the international standard for most curative gastric cancer operations.

Whenever possible, the digestive tract is reconstructed to restore normal food passage after surgery.

Depending on the patient's condition, surgery may be performed using open, laparoscopic, or robotic-assisted techniques.

Types of Gastric Cancer Surgery

The type of surgery depends on the tumor's location and stage and may include:

• Partial Gastrectomy – removal of the diseased portion of the stomach.

• Total Gastrectomy – removal of the entire stomach.

• D2 Lymph Node Dissection – removal of regional lymph nodes to improve cancer control and staging accuracy.

• Reconstructive procedures to restore digestive continuity after stomach removal.

Recovery After Surgery

Recovery depends on the extent of surgery and the patient's general condition.

Patients are generally advised to:

• Follow a gradual nutritional rehabilitation program.

• Eat smaller, more frequent meals.

• Walk regularly after surgery.

• Attend follow-up appointments.

• Work closely with dietitians to maintain adequate nutrition.

Some patients may require chemotherapy after surgery depending on the pathological stage of the cancer.

Why is Early Treatment Important?

Early diagnosis offers the greatest opportunity for complete tumor removal and long-term survival.

When stomach cancer is detected before it spreads beyond the stomach, treatment is generally more effective and less extensive.

A Message to Patients

Persistent stomach discomfort, unexplained weight loss, difficulty eating, or ongoing digestive symptoms should never be ignored. Early consultation with an experienced gastrointestinal surgery team can lead to timely diagnosis and access to advanced surgical treatment, significantly improving the chances of successful recovery.

Frequently Asked Questions

Can stomach cancer be cured with surgery?

Yes. If diagnosed at an early stage and completely removed, surgery offers the best chance for long-term cure. Some patients may also require chemotherapy before or after surgery.

Will my entire stomach need to be removed?

Not always. Many patients are candidates for partial gastrectomy, while total gastrectomy is reserved for tumors involving larger portions of the stomach.

Can I eat normally after stomach surgery?

Yes. Most patients gradually return to a normal diet, although they usually need to eat smaller, more frequent meals. Nutritional counseling plays an important role during recovery.
