The stomach is an organ located in the upper part of the abdomen. It contains strong acids and helps churn and digest food. Any uncontrolled growth in the stomach is cancer.
Stomach cancer, also called gastric cancer, is one of the common digestive cancers. It can take years to develop and usually begins in the surface lining of the stomach rather than deep in the muscle.
If detected early, complete removal of the tumor can provide the best chance of long-term control and cure.
There is rarely one clear reason someone develops stomach cancer. Several factors can increase the risk.
Many patients with stomach cancer have no identifiable risk factor.
Request an appointmentEarly stomach cancer can be difficult to recognize. Many people initially assume their symptoms are routine heartburn, gas, or acidity.
The exact operation depends on the location and extent of the tumor.
Stomach cancer can spread to lymph nodes located along the neighboring blood vessels. A D2 lymph node dissection involves removal of the stomach along with the relevant surrounding lymph-node groups.
This requires meticulous surgical technique and is an important component of surgery for appropriately selected patients with gastric cancer.
Surgery around major blood vessels in the abdomen requires precision. Robotic surgical systems provide high-definition three-dimensional visualization and articulated instruments that can assist with precise dissection in confined spaces.
In appropriately selected patients, minimally invasive robotic surgery may help with lymph-node dissection, blood-loss control, postoperative recovery, and return to normal activities.
Stomach cancer care may involve treatments in addition to surgery, depending on the stage and tumor characteristics.
Recovery after stomach cancer surgery varies from person to person. Many patients are encouraged to walk soon after surgery, and oral nutrition is gradually resumed according to their condition.
Minimally invasive techniques may support recovery in appropriately selected patients. Regular follow-up appointments, blood tests, nutritional monitoring, and imaging when required help monitor recovery and cancer status.
Our priority in stomach cancer surgery is complete tumor removal with appropriate margins while performing a thorough and safe lymph-node clearance. Robotic platforms can provide visualization and instrument control that assist with precise dissection around important blood vessels.
For selected larger tumors, chemotherapy before surgery may reduce the tumor burden and help make subsequent surgery more manageable. Recovery, nutrition, and gradual adaptation to eating patterns are important parts of postoperative care.
Stomach cancer, medically known as gastric cancer, is a cancer that develops in the lining or other tissues of the stomach.
Early symptoms may be mild and can include persistent acidity or indigestion, upper abdominal discomfort, bloating, nausea, feeling full after a small meal, or unexplained weight loss.
The main diagnostic test is an upper GI endoscopy. A thin camera is passed through the mouth to examine the stomach lining and obtain a tissue sample for biopsy when required.
Treatment and outcomes depend on the type and stage of cancer. When stomach cancer is detected at an early stage and can be completely treated, long-term control or cure may be possible.
Robotic gastrectomy is a minimally invasive operation in which the surgeon uses robotic instruments and a camera system to remove part or all of the stomach through small surgical incisions.
In appropriately selected patients, minimally invasive robotic surgery may involve smaller incisions, reduced blood loss, and faster recovery. The exact benefits depend on the procedure, patient's condition, and surgical circumstances.
Gastrectomy is an operation to remove part of the stomach, called a partial gastrectomy, or the entire stomach, called a total gastrectomy.
D2 lymph node dissection is the removal of specific lymph-node groups surrounding the stomach and its major blood vessels as part of appropriate gastric cancer surgery.
Some patients receive chemotherapy before surgery, after surgery, or both. The treatment plan depends on the stage and biological characteristics of the cancer.
Yes, people can adapt to life after total gastrectomy. The food pipe is connected directly to the small bowel, and eating smaller, more frequent meals along with appropriate nutritional and vitamin supplementation may be recommended.
Initially, liquids are introduced according to postoperative recovery. The diet is gradually advanced, with nutrition guidance provided as needed.
Outlook depends on factors including the stage, tumor characteristics, response to treatment, overall health, and whether complete treatment is possible.
Persistent indigestion, unexplained weight loss, repeated vomiting, vomiting blood, or black, tarry stools should be evaluated by a qualified medical professional.
