Minimally invasive robotic and laparoscopic gastrectomy: a new ray of hope for gastric cancer – ETHealthWorld IG News

IG news Update,

The stomach is a muscular J-shaped sac-like structure that serves as a reservoir for food primarily located in the upper and left sides of the stomach and is an important part of the digestive tract of the gastrointestinal system. It produces enzymes (substances that cause chemical reactions) and acids (digestive juices). This mixture of enzymes and digestive juices breaks down the food so that it can pass into our small intestine (duodenum).

Gastric cancer, also called stomach cancer, can occur anywhere in any part of the stomach (fundus, body, also called the proximal stomach, and the antrum and pylorus, also called the distal part of the stomach)- Where the abnormal growth of malignant cells invades the abdomen and nearby and outside organs such as the liver, lungs, peritoneum and bone etc.

symptoms of gastric cancer

Major symptoms of gastric cancer include:
• difficulty swallowing
• Feeling full or bloated even after eating small amounts of food
• Heartburn or acidity
• Nausea and vomiting with dyspepsia
• severe abdominal pain
• Unintentional weight loss

due to gastric cancer

There is no definite cause as to what can cause colon cancer. However, risk factors that trigger this disease include:
• Chronic gastroesophageal reflux disease
• overweight
• Eating a low fiber diet
• Bad eating habits like consuming high salt food, deep frying
• family history
• Infection with Helicobacter pylori
• Chronic gastritis
• smoking
• Colon polyps


Gastric cancer is diagnosed by running a variety of tests, including blood tests, and imaging tests such as endoscopic ultrasound, CT, PET-CT, biopsy, or diagnostic laparoscopy.


Surgery forms the first line of defense when combating gastric cancer (in its early stages). Over the past decade, there has been a rapid increase in surgical techniques for the treatment of colon cancer, requiring the exceptional expertise of surgical oncologists (gastro intestinal surgeons) to provide significant relief for patients undergoing treatment for gastric cancer. . Over the past decade or more, surgical treatment for gastric cancer has seen unparalleled medical advances, with the advent of minimally invasive procedures such as robotic, laparoscopic procedures that ensure rapid recovery.

What is gastrectomy?

Gastrectomy is defined as the complete or partial removal of the stomach for the treatment of various medical conditions, mainly for cancer.

There are four types of gastrectomy – total gastrectomy, subtotal gastrectomy, distal gastrectomy, extended total gastrectomy (removal of the distal food pipe) and proximal gastrectomy.

Benefits of minimally invasive robotic, laparoscopic gastrectomy procedures

open surgery, laparoscopy, or robotic surgery; The principles include the same – removal of the cancer and surrounding structures (in the case of metastasis) without compromising the cure. Minimally invasive surgical procedures provide better outcomes than open surgery in patients undergoing gastrectomy for the treatment of gastric cancer. Extensively trained gastrointestinal surgeons adopting robotic or laparoscopic surgery to ensure a fast, safe and viable alternative to conservative open surgery.

Some of the benefits of minimally invasive procedures are:

• Reduction in post-operative pain
• Shorter hospital stay and faster recovery
• Minimum mark
• Less strain on the immune system
• Small incisions
• Less chance of infection and hernia formation

How is laparoscopic gastrectomy performed?

Laparoscopic gastrectomy is a widely recommended and adopted minimally invasive surgical procedure to destroy cancer cells, even in locally advanced stages of gastric cancer.

During the procedure, several small incisions (key holes) are made by the surgeons. Surgical instruments are sent inside to access the diseased part for its dissection and removal. Surgery aimed at eliminating cancer cells may take a little longer than open gastrectomy, but the patient recovers faster due to less blood loss and pain. It has 2D vision and the ergonomics of the equipment are difficult due to the straightness.

The patient will be able to resume regular duty and eat normally within a week or so.

How is Robotic Gastrectomy Performed?

Robotic-assisted gastrectomy is performed by making a small 8 to 12 mm incision (key hole) at the navel and three other small incisions in the upper abdomen for assistive devices. The surgeon sits at the console during the procedure, directing the robotic arms to perform the operation. These robotic arms work like human hands with full, precise dexterity, finger movements and wrist movements (performed by surgeon hand actions transmitted through instruments with digital interaction). Even while performing the surgery, the surgeon could see a large, high-definition 3D view of the organs, enabling the surgeon to perform procedures such as dissection, bowel connections, and stapling.

The advantages of robotic gastrectomy are many. It is often recommended for removal of gastrointestinal stromal tumors, gastric adenocarcinoma, or even a rare form of carcinoid or neuroendocrine tumor.

This procedure is less painful than traditional open gastrectomy. Other benefits include:

• Less blood loss and fewer blood transfusions
• Lower risk of infection
• Early feed start
• Rapid return to normalcy

Since its inception, robotic surgery has been extensively performed in thousands of procedures around the world. These techniques have gained wide popularity due to their positive effects on patient recovery, fewer complications and shorter hospital stays. If we focus specifically on cancer, these surgeries are widely used in the treatment of gastrointestinal cancer. To know more about the benefits of robotic surgery for gastric cancer care, you may consult an oncologist for further guidance.
