ESG (Endoscopic Sleeve Gastroplasty)

What is ESG (endoscopic sleeve gastroplasty)?

Endoscopic sleeve gastroplasty (ESG) is a minimally invasive procedure designed to aid weight loss by reducing the stomach's size using an endoscopic suturing device. Unlike conventional weight loss surgeries such as gastric bypass or sleeve gastrectomy, ESG doesn't necessitate any abdominal incisions. Instead, it is conducted entirely through the mouth using an endoscope, a slender, flexible tube equipped with a camera and suturing tools. Throughout the procedure, the stomach's capacity is diminished by forming a sleeve-like shape, constraining its food intake capacity and facilitating weight loss.

When is an ESG (endoscopic sleeve gastroplasty) procedure indicated?

An endoscopic sleeve gastroplasty (ESG) procedure is generally advised for individuals who are considerably overweight or obese and have not achieved success with alternative weight loss approaches like diet and exercise. Candidates for ESG usually have a body mass index (BMI) ranging from 30 to 40 and may have obesity-related health conditions such as diabetes, high blood pressure, or sleep apnoea. It is important to note that ESG is not suitable for everyone, and candidacy for the procedure is determined on a case-by-case basis by a qualified healthcare professional, such as Dr Andrew Viljoen.

How is an ESG (endoscopic sleeve gastroplasty) procedure performed?

The ESG procedure is performed under sedation or general anaesthesia to ensure patient comfort throughout the process. Once the patient is sedated, Dr Andrew Viljoen inserts the endoscope through the mouth and into the stomach. The endoscope's camera delivers live images of the stomach's inner lining, enabling Dr Viljoen to position the sutures precisely and form the sleeve-like structure. Utilizing specialized instruments connected to the endoscope, Dr Viljoen proceeds to insert a succession of sutures along the stomach's length, effectively diminishing its size. The procedure usually lasts between 60 to 90 minutes, and the majority of patients can be discharged on the same day. Subsequent to the procedure, patients are instructed to adhere to a designated diet and lifestyle adjustments to optimize weight loss outcomes and reduce the risk of potential complications.

1How effective is ESG for weight loss?
ESG has been shown to be an effective weight loss option for many patients. Research findings indicate that those undergoing ESG can attain notable weight loss, with a majority of participants seeing a decrease in excess body weight of 50% or greater within the initial year post-procedure. Nevertheless, outcomes may differ from person to person, and sustained success hinges on variables like dietary choices, physical activity, and lifestyle habits.
2What potential risks and complications are linked with ESG?
Similar to any medical procedure, ESG presents certain risks and potential complications. These may encompass bleeding, infection, stomach or oesophagus perforation, and adverse reactions to anaesthesia. Additionally, some patients may experience nausea, vomiting, or difficulty swallowing following the procedure. It is important to discuss these risks with your healthcare provider and ensure that you understand the potential benefits and drawbacks of ESG before undergoing the procedure.
3What is the recovery process like after ESG?
The recuperation period after ESG is generally swift and entails minimal discomfort. The majority of patients can be discharged on the same day as the procedure and return to their regular activities within a few days. Nonetheless, patients are encouraged to adhere to a prescribed diet and make lifestyle adjustments to optimize weight loss outcomes and reduce the likelihood of complications. Your healthcare provider will furnish comprehensive guidance on post-procedure care and schedule follow-up appointments.
