2410Gastrectomy, is a surgical procedure that involves the removal of a part or all of the stomach. This procedure is used to treat stomach cancer, esophageal cancer, obesity, stomach ulcers and non-cancerous tumors.
Weight loss is achieved through diet control and exercises, however, certain morbidly obese find it challenging to lose weight using traditional methods. For such patients, sleeve gastrectomy offers obese patients the option to staple (or remove) certain parts of their stomach, and as a result, drastically reduce the amount of food the stomach can digest.
Along with obesity, patients who have been diagnosed with stomach or esophageal cancer are also eligible to undergo this procedure.
Depending on the severity of the symptoms, the surgeon would recommend partial or complete removal of the stomach. This can be achieved through the following types of gastrectomy:
Gastrectomy is performed using the following techniques:
Before the start of the procedure, the doctor will run a physical examination and also review the patient’s history of any existing conditions, such as diabetes. The doctor will also review any existing medications and check if they can cause any complication during the procedure.
Gastrectomy is used to treat weight-related disorders, such as:
Through this procedure, patients suffering from obesity can get a boost in starting their weight loss journey, and begin adapting a healthy, active lifestyle, since many morbidly obese patients find it hard to start and continue with any weight loss regimen.
While sleeve gastrectomy has a high success rate and poses minimal complications, there are certain risks associated with this procedure:
Before the start of the procedure, patients will be required to discuss existing medications and any specific guideline that is required to fully prepare the patient. On the day of the surgery, patients are administered general anesthesia for the entirety of the procedure.
For a sleeve gastrectomy procedure, the surgeon will start by making small incisions in the upper abdomen. Through these incisions, the surgeon would insert surgical instruments and proceed to staple the stomach to create a narrow sleeve, and remove the larger portion of the stomach. This procedure usually takes one to two hours.
Once the procedure is completed, the patient is kept under observation and the recovery is monitored. On discharge, patients are asked to follow a liquid diet that’s free from sugar and noncarbonated. After a week, patients are then asked to consume a semi-solid diet that’s easy to swallow. After 3 to 4 weeks, the patients are allowed to consume regular food. Vitamin supplements are also prescribed to ensure patients get the right nutrition.
Patients who have completed sleeve gastrectomy are advised to make the following changes to their existing lifestyle –
Sleeve gastrectomy is a widely administered surgical procedure to treat weight-related disorders, especially for patients who face trouble losing weight through traditional methods. By removing parts or the entire stomach, patients are no longer able to consume high quantities of food, and as a result, they can achieve weight loss.
Once the procedure is completed, patients are expected to follow a fixed diet and make lifestyle changes to ensure the body adjusts to the reduced working of the stomach.
Sleeve gastrectomy procedures usually take 1 to 2 hours to complete.
Depending on the extent of symptoms, surgeons will recommend either certain parts of the stomach, or the full stomach.
Once the sleeve gastrectomy procedure is completed, most patients report losing 50% of weight within 24 months.
No, but the existing parts of the stomach can stretch to digest any extra portions of food.
Patients are advised to avoid alcohol for up to 6 months once the procedure is completed.
