Gastric surgery

Gastric surgery — total and subtotal gastrectomy for the treatment of gastric cancer and complex stomach diseases.

Removal of all (total) or part (subtotal) of the stomach with D2 lymph node dissection in gastric cancer and complex stomach diseases.

Indication

  • Surgical treatment of gastric cancer (gastric adenocarcinoma)
  • Lymphoma in the stomach region and gastrointestinal stromal tumor (GIST)
  • Advanced complications of peptic ulcer disease unresponsive to medical therapy (perforation, bleeding, stricture)
  • Recurrent complications related to prior gastric surgery
  • Severe and irreversible gastric outlet obstruction
  • Prophylactic gastrectomy in certain hereditary syndromes (specialized indication)

Preparation

  • Diagnosis confirmed by upper gastrointestinal endoscopy and biopsy
  • Staging with CT, and endoscopic ultrasound (EUS) and PET-CT when needed
  • Complete blood count, biochemistry, coagulation studies, and nutritional status (albumin) assessment
  • Smoking cessation, nutritional support, and adjustment of blood thinners
  • At least 8 hours of fasting and skin preparation before the operation

How it's performed

  1. The abdomen is opened by an open or laparoscopic approach under general anesthesia
  2. The stomach is removed totally (total gastrectomy) or partially (subtotal/distal gastrectomy) according to tumor location
  3. Surrounding tissues and a D2 lymph node dissection are performed; appropriate surgical margins are achieved
  4. A new connection between the esophagus and small intestine is created with an appropriate technique (Roux-en-Y)
  5. The abdomen is irrigated, bleeding is controlled, and a drain is placed
  6. Removed tissue and lymph nodes are sent for pathology

Post-procedure

  • After intensive care follow-up, transfer to the ward; total hospital stay is typically 7-14 days
  • Liquid diet in the first days, followed by gradual transition to soft and solid foods
  • Frequent small meals (especially after total gastrectomy to reduce dumping)
  • Vitamin B12, iron, calcium, and overall nutritional follow-up (long-term supplementation if needed)
  • Adjuvant chemotherapy/radiotherapy planning together with oncology based on pathological stage

Risks

  • Anastomotic leak or stricture
  • Bleeding, infection, and intra-abdominal abscess
  • Nutritional deficiencies (weight loss, B12 and iron deficiency)
  • Dumping syndrome (palpitations, sweating, diarrhea after eating)
  • Thromboembolic and respiratory complications

FAQ

After my entire stomach is removed, can I eat normally?

Yes, but in frequent small meals. With dietitian support, a gradual transition to different foods is achieved.

Are vitamin supplements needed after total gastrectomy?

Yes. Vitamin B12 in particular is given lifelong as injections or as high-dose oral supplementation; iron and calcium deficiencies are also monitored.

Will chemotherapy definitely be needed?

The need is determined by pathological stage, lymph node involvement, and molecular features; it is planned at a multidisciplinary tumor board.

Is laparoscopic surgery possible?

Depending on tumor location, stage, and patient condition, laparoscopic gastrectomy may be preferred in suitable cases.
