What Happens During Stomach Cancer Surgery in Mumbai? A Step-by-Step Guide
Being told that you need stomach cancer surgery can feel overwhelming, especially if you're unsure about what the procedure involves. Understanding each step of the surgical process can help reduce anxiety and prepare you for your treatment journey. Stomach cancer surgery is carefully planned to remove the cancer while preserving as much healthy tissue as possible. The exact procedure depends on the size, stage, and location of the tumor, as well as your overall health.
Here's a step-by-step guide to help you understand what typically happens during stomach cancer surgery.
Step 1: Pre-Surgical Evaluation
Before surgery, your medical team performs a detailed assessment to ensure the safest treatment approach.
This may include:
Blood tests
Endoscopy
CT scan or PET scan
Biopsy review
Heart and lung evaluation
Nutritional assessment
These investigations help determine the stage of the cancer and allow the surgeon to plan the most appropriate procedure.
Step 2: Administration of Anesthesia
On the day of surgery, you will be taken to the operating room, where an anesthesiologist will administer general anesthesia. This ensures that you remain asleep and pain-free throughout the operation.
Your vital signs, including heart rate, blood pressure, oxygen levels, and breathing, are continuously monitored during the procedure to maintain your safety.
Step 3: Accessing the Stomach
The surgeon begins the operation by reaching the stomach through either:
A traditional open incision, or
A minimally invasive laparoscopic or robotic-assisted approach, depending on your condition.
The choice of technique depends on factors such as the size of the tumor, its location, and whether the cancer has spread to nearby tissues.
Step 4: Removing the Cancerous Tissue
The main objective of surgery is to remove the tumor completely with a margin of healthy tissue around it.
Depending on the extent of the disease, the surgeon may perform:
Partial Gastrectomy: Only the affected portion of the stomach is removed.
Total Gastrectomy: The entire stomach is removed when cancer involves a larger area.
The surgical approach is selected based on what offers the best chance of complete cancer removal while maintaining digestive function whenever possible.
Step 5: Removal of Nearby Lymph Nodes
Stomach cancer can spread through the lymphatic system. Therefore, the surgeon usually removes nearby lymph nodes during the operation.
This helps:
Determine the exact stage of the cancer.
Check whether cancer cells have spread.
Guide future treatment decisions, including chemotherapy if needed.
Lymph node evaluation plays an important role in improving treatment planning and long-term outcomes.
Step 6: Reconstructing the Digestive Tract
Once the cancerous tissue has been removed, the digestive system must be reconstructed.
Depending on the type of surgery performed:
The remaining part of the stomach is connected to the small intestine.
If the entire stomach is removed, the esophagus is directly connected to the small intestine.
This reconstruction allows food to continue passing through the digestive system, although patients may need to adjust their eating habits during recovery.
Step 7: Final Safety Check and Closing the Incision
Before completing the operation, the surgeon carefully checks for:
Bleeding
Proper blood supply to the reconstructed digestive tract
Secure surgical connections
Overall stability of the surgical area
Once everything is confirmed, the incision is closed using sutures or surgical staples, and a sterile dressing is applied.
What Happens After Surgery?
After the procedure, you will be moved to the recovery area, where your healthcare team will closely monitor your condition.
During the first few days, care focuses on:
Pain management
Preventing infection
Gradually restarting nutrition
Encouraging gentle movement
Monitoring wound healing
Most patients begin with liquids before slowly progressing to soft foods as advised by their surgical team and dietitian.
Recovery and Follow-Up Care
Recovery time varies depending on the type of surgery and your overall health. Regular follow-up appointments help monitor healing and identify any potential complications early.
Your doctor may also recommend:
Nutritional counseling
Vitamin supplementation
Lifestyle modifications
Additional cancer treatments, such as chemotherapy, if required
Routine imaging and health check-ups
Following your surgeon's advice is essential for achieving the best possible recovery.
