Understanding Laparoscopic Surgery for Gastric Cancer: A Patient's Guide

What is Gastric Cancer?

Gastric cancer, also known as stomach cancer, is a malignant tumor that originates from the lining of the stomach. It is a serious condition that requires prompt medical attention. Common symptoms may include abdominal pain, nausea, vomiting, weight loss, and difficulty swallowing. Early detection and treatment are crucial for improving outcomes.

What is Laparoscopic Surgery?

Laparoscopic surgery, often referred to as minimally invasive surgery, is a technique that allows surgeons to perform operations through small incisions using a laparoscope—a thin, flexible tube with a camera and light at the end. The camera sends images to a monitor, guiding the surgeon during the procedure. This approach contrasts with traditional open surgery, which involves larger incisions.

Benefits of Laparoscopic Surgery

Laparoscopic surgery offers several advantages over traditional open surgery, including:

  • Smaller Incisions: Leads to less scarring and a quicker recovery.
  • Reduced Pain: Smaller incisions generally cause less post-operative pain.
  • Shorter Hospital Stay: Patients often recover faster and spend less time in the hospital.
  • Faster Return to Normal Activities: The overall recovery time is typically shorter, allowing patients to resume their normal activities sooner.
  • Lower Risk of Infection: Smaller incisions reduce the risk of infections.

Laparoscopic Surgery for Gastric Cancer

When treating gastric cancer, laparoscopic surgery can be used to remove part or all of the stomach (gastrectomy) along with nearby lymph nodes. The specific type of surgery depends on the cancer's location, size, and stage. Here are the common types of laparoscopic gastrectomy:

  1. Laparoscopic Partial Gastrectomy: Removal of the cancerous part of the stomach.
  2. Laparoscopic Total Gastrectomy: Removal of the entire stomach, often required for more advanced cancers.
  3. Laparoscopic Lymphadenectomy: Removal of nearby lymph nodes to check for the spread of cancer.

The Procedure

Here is an overview of what you can expect before, during, and after laparoscopic gastric cancer surgery:

Before the Surgery

  • Consultation and Evaluation: Your surgeon will evaluate your medical history, perform a physical examination, and may order imaging tests (CT scan, endoscopy) to plan the surgery.
  • Pre-operative Preparation: You may need to follow specific dietary restrictions, take certain medications, and refrain from eating or drinking for a few hours before the surgery.

During the Surgery

  • Anesthesia: You will be given general anesthesia, ensuring you are asleep and pain-free during the procedure.
  • Incisions and Laparoscope Insertion: The surgeon will make several small incisions in your abdomen and insert the laparoscope and other surgical instruments.
  • Removal of Tumor and Affected Areas: The surgeon will carefully remove the cancerous part of the stomach and possibly some surrounding tissue and lymph nodes.
  • Closure: The small incisions are closed with sutures or staples.

After the Surgery

  • Recovery: You will be monitored in the recovery room until the anesthesia wears off. You may need to stay in the hospital for a few days.
  • Pain Management: Pain medications will be provided to manage any discomfort.
  • Dietary Adjustments: Initially, you will be on a liquid diet, gradually progressing to solid foods as your digestive system adjusts.
  • Follow-Up Appointments: Regular follow-ups with your surgeon and oncologist are essential to monitor your recovery and check for any signs of cancer recurrence.

Potential Risks and Complications

As with any surgery, laparoscopic gastric cancer surgery carries risks, including:

  • Bleeding
  • Infection
  • Anastomotic Leak: Leakage where the stomach or intestines are reconnected.
  • Nutritional Deficiencies: Due to changes in the digestive system.
  • Bowel Obstruction: Blockage in the intestines.


Laparoscopic surgery is a valuable option for treating gastric cancer, offering the benefits of minimally invasive techniques. If you or a loved one has been diagnosed with gastric cancer, discussing the potential for laparoscopic surgery with your healthcare team can help determine the best treatment plan tailored to your needs.

For more detailed information and personalized advice, always consult your surgeon or oncologist. Early detection and treatment are key to improving outcomes and enhancing the quality of life for those affected by gastric cancer.
