Sleeve Gastrectomy: What It Is and When to Avoid It

What Is Sleeve Gastrectomy?

Sleeve gastrectomy, commonly referred to as a gastrectomy, is a surgical procedure designed to help individuals with obesity lose excess weight. This procedure falls under the broader category of bariatric surgery, aimed at treating obesity.

As an invasive procedure, it’s important to understand the potential complications of sleeve gastrectomy and when it is recommended versus when it might be better to avoid it.

In practical terms, this surgery involves reducing the patient’s stomach by removing a significant portion, specifically the gastric fundus. Weight loss is achieved partly because patients experience reduced hunger after the procedure. The removal of the gastric fundus, which produces hormones associated with hunger, greatly aids in this regard. As a result, patients consciously consume less food, leading to significant weight loss benefits.

Risks of the Procedure

As an irreversible operation, sleeve gastrectomy permanently removes a portion of the stomach. This permanence means patients should consult with healthcare professionals to assess whether this surgery is truly necessary.

Among the risks and possible post-operative complications, one of the most common is stomach dilation, which can occur when patients do not adhere to the prescribed diet. This diet is designed to avoid straining the reduced size of the stomach.

Another possible complication is gastroesophageal reflux. However, this risk should be weighed against the fact that many patients undergoing sleeve gastrectomy may already be prone to reflux due to their obesity.

When to Avoid Sleeve Gastrectomy

Undergoing gastrectomy means committing to an invasive procedure and adhering to specific dietary and lifestyle adjustments during the post-operative phase. A careful risk-benefit assessment is necessary, and the procedure should be avoided unless all justifying conditions are met.

Ultimately, the decision regarding the appropriateness of the surgery lies with qualified professionals. Generally, sleeve gastrectomy is recommended in specific situations, such as for patients with severe obesity and a BMI of 50 or higher. In these cases, the potential complications of the procedure are considered less risky than the health risks posed by obesity itself. The surgery may also be an option for patients with third-degree obesity, but only if other methods, like diet and exercise, have not resulted in sufficient weight loss.
