A gastrectomy is a surgical procedure that involves removing part or all of the stomach. The procedure is typically performed to treat stomach cancer or severe obesity. Gastrectomies can be performed in several ways, including partial gastrectomy, subtotal gastrectomy, and total gastrectomy. In this article, we will discuss what a gastrectomy operation is and why it is performed.
Reasons for Gastrectomy
Gastrectomies are performed for a variety of reasons, including:
- Stomach cancer – Gastrectomies are often performed to remove early-stage stomach cancer before it has spread to other parts of the body.
- Severe obesity – Gastrectomies can also be performed to treat severe obesity, particularly when other weight loss methods, such as diet and exercise, have been unsuccessful.
- Gastroesophageal reflux disease (GERD) – In some cases, gastrectomies may be performed to treat GERD, a condition in which stomach acid flows back into the esophagus and causes discomfort and damage.
- Gastric ulcers – Gastrectomies may also be performed to treat gastric ulcers, which are sores that form on the lining of the stomach.
Types of Gastrectomy
There are several types of gastrectomy, including:
- Partial gastrectomy – A partial gastrectomy involves removing only a portion of the stomach. This type of gastrectomy is typically performed to treat early-stage stomach cancer or gastric ulcers.
- Subtotal gastrectomy – A subtotal gastrectomy involves removing a portion of the stomach, including the upper portion where the majority of the stomach’s acid production occurs. This type of gastrectomy is typically performed to treat GERD or severe obesity.
- Total gastrectomy – A total gastrectomy involves removing the entire stomach. This type of gastrectomy is typically performed to treat advanced-stage stomach cancer.
Risks and Complications of Gastrectomy
Like any surgical procedure, gastrectomy carries certain risks and complications, including:
- Infection – Infection is a common risk of gastrectomy, and patients will typically be given antibiotics to prevent infection after the procedure.
- Bleeding – Bleeding can occur during or after a gastrectomy, and in rare cases, a blood transfusion may be necessary.
- Leakage from the surgical site – Leakage from the surgical site can occur, and in severe cases, it can lead to peritonitis, a serious infection of the abdominal cavity.
- Nutritional deficiencies – Gastrectomies can cause nutritional deficiencies, particularly if the entire stomach is removed. Patients will typically be advised to follow a balanced diet and may need to take vitamin and mineral supplements to prevent deficiencies.
- Dumping syndrome – Dumping syndrome is a common complication of gastrectomy, particularly after a total gastrectomy. This condition occurs when food moves too quickly through the small intestine and can cause symptoms such as nausea, vomiting, and diarrhea.
Recovery After Gastrectomy
Recovery after a gastrectomy can vary depending on the type of procedure performed and the patient’s overall health. Patients will typically need to stay in the hospital for several days after the procedure and will be advised to rest at home for several weeks to allow the surgical site to heal. Patients will also need to follow a special diet after the procedure to help their bodies adjust to the changes in their digestive system.

Gastrectomies carry certain risks and complications, and recovery can vary depending on the type of procedure and the patient’s overall health. Patients should discuss the potential benefits and risks of gastrectomy with their doctor before undergoing the procedure.
