The difference between sleeve gastrectomy and gastric bypass

To know the difference between sleeve gastrectomy and gastric bypass, you must know that the purpose of both operations is the same, which is to get rid of excess weight, and reduce health problems related to obesity, but there are some differences between the two operations that we will address through this article:

What is the process of sleeve gastrectomy technically?

It is a surgery that is done by endoscopy without any surgical intervention, through three to four holes (on average four) in the abdomen, and the duration of the operation ranges up to approximately 50 minutes, so that the surgeon cuts through a tube placed inside the stomach and the cut is done on its edges, and The shearing percentage of the stomach is determined according to the doctor’s discretion, and a volume of 125 ml is left from the stomach. After the operation, the stomach is examined in four stages before the patient leaves the hospital, to ensure that there is no leakage from the stomach.

What is the technical process of gastric bypass?

It is a surgical operation in which the surgeon connects the esophagus to the small intestine, using a 25% part of the stomach and connects them to the small intestine. The operation is also done without surgical intervention, through the laparoscope through three to five holes (average four) in the abdomen and the duration of the operation hour.

What is the difference between sleeve gastrectomy and gastric bypass?

What is the difference between sleeve gastrectomy and gastric bypass in terms of results and benefits?

Sleeve gastrectomy focuses on the goal of reducing the size of the stomach and thus eating much smaller quantities than before and fewer calories gained, in addition to inhibiting the hunger hormone, which reduces appetite and the feeling of hunger.

While the bypass operation achieves the previous results while reducing the absorption of food and drink ingested inside the intestine, as a result of cutting a good part of the intestine responsible for the absorption of food.

 

What is the difference between sleeve gastrectomy and gastric bypass in terms of side effects and harms?

Gastric bypass has more complications when compared to sleeve gastrectomy, and these complications have an incidence of 4%, according to the American Society for Bariatric Surgery, and are:

• Gastric bypass patients suffer from malabsorption of nutrients and vitamins more than gastric sleeve patients, as a result of removing a part of the intestine that is responsible for absorbing vitamins and minerals. The gastric bypass patient needs to take nutritional supplements such as iron and vitamin B12 for life.
• The occurrence of partial separation of the stomach and intestines, which were joined together in a few cases.
• The possibility of an expansion of the stomach after the gastric bypass operation is greater compared to the sleeve gastrectomy, where the size of the stomach is somewhat fixed in the sleeve gastrectomy.

 

As for the harms and common side effects of both operations, they are:

• Infection and inflammation.
• The patient suffers from malnutrition and poor absorption of nutrients.
• Bleeding or clots.
• The occurrence of vomiting and nausea.

 

What is the difference in terms of cost?

It differs between surgeries, according to the patient’s condition, and the cost depends on several factors:

• The country in which the operation takes place.
• Whether the patient had any complications during the surgery.
• The type of surgery.
