The duration of gastric sleeve surgery can vary depending on several factors. These include the level of obesity, anatomical features, surgical techniques, and the risk of complications. Generally, the duration of gastric sleeve surgery can range from 1 to 2 hours.

The surgery is typically performed using the laparoscopic (minimally invasive) surgical method. In this method, small incisions are made in the abdominal area, and an optical device called a laparoscope and surgical instruments are inserted into the abdomen. The laparoscope provides the operating surgeon with visual feedback and allows for control of the surgical instruments.

During gastric sleeve surgery, incisions are made on the stomach, and a large portion of it is removed. The remaining portion of the stomach is reshaped into a narrower, tube-like structure. This step constitutes the main part of the surgery and usually takes about 30-60 minutes.

One factor that affects the duration of the surgery is the level of obesity. In individuals with a higher BMI, the presence of more adipose tissue and the positioning of abdominal organs can slightly extend the duration of the surgery.

The experience of the surgical team and the complexity of the procedure can also influence the duration of the surgery. Surgeries performed in a center with an experienced bariatric surgeon and surgical team may have a shorter duration.

It’s important to note that the duration of the surgery is a secondary factor to the success and safety of the procedure. What matters most is that the surgery is performed appropriately and safely. Therefore, the focus should be on the quality and outcomes of the surgery rather than the duration.

Before the surgery, your bariatric surgeon can provide more specific information about the duration of the surgery and better guide your expectations.
