Gastrectomy

Illustration of the stomach anatomy

A gastrectomy is a surgical procedure where all or part of the stomach is removed. This operation is typically performed to treat stomach cancer, severe peptic ulcers, or other stomach-related diseases. The procedure can be classified into several types depending on the portion of the stomach that is removed.

Types of Gastrectomy

Partial Gastrectomy

A partial gastrectomy involves the removal of a portion of the stomach. This is often done to remove a tumor or to treat severe ulcers. The remaining part of the stomach is then reconnected to the small intestine.

Total Gastrectomy

In a total gastrectomy, the entire stomach is removed. The esophagus is then directly connected to the small intestine. This procedure is more extensive and is usually reserved for cases where cancer has spread throughout the stomach.

Sleeve Gastrectomy

A sleeve gastrectomy is a type of bariatric surgery where a large portion of the stomach is removed, leaving a tube-like structure. This procedure is primarily used to treat obesity.

Indications for Gastrectomy

Gastrectomy is indicated for several conditions, including:

• Stomach cancer
• Severe peptic ulcer disease
• Non-cancerous tumors
• Obesity (in the case of sleeve gastrectomy)

Surgical Procedure

The procedure can be performed using open surgery or laparoscopic surgery. In open surgery, a large incision is made in the abdomen to access the stomach. In laparoscopic surgery, several small incisions are made, and the surgery is performed using a camera and special instruments.

Postoperative Care

After a gastrectomy, patients may need to stay in the hospital for several days. Nutritional support is crucial, as the stomach plays a significant role in digestion. Patients may need to follow a special diet and take vitamin supplements to compensate for the reduced absorption of nutrients.

Complications

Potential complications of gastrectomy include:

• Infection
• Bleeding
• Nutritional deficiencies
• Dumping syndrome, where food moves too quickly from the stomach to the small intestine
