Esg: Procedure, Benefits, Risks, Recovery and Alternatives

Esg: The Procedure

Endoscopic Sleeve Gastroplasty (ESG) is an innovative, minimally invasive weight-loss procedure that is rapidly gaining popularity among patients seeking alternatives to traditional bariatric surgery. If you or a loved one are considering ESG, understanding the step-by-step process can help reduce anxiety and set realistic expectations. ESG offers a unique approach: it mimics some of the effects of surgical sleeve gastrectomy, but without any incisions or removal of stomach tissue.

Step	Description	Duration	Reference
Preparation	Pre-procedure assessment, fasting, anesthesia	1-2 hours prep	3 4 5
ESG Procedure	Endoscopic suturing to reduce stomach volume	60–120 minutes	3 4 5
Recovery	Observation post-procedure, discharge	Same day/outpatient	3 4 5 11
Follow-up	Scheduled visits to monitor progress	Months–years	4 11 15

Table 1: ESG Procedure Overview

What Happens During ESG?

ESG is performed entirely through the mouth using a flexible endoscope equipped with a suturing device. Patients are placed under general anesthesia or deep sedation. The endoscopist advances the device into the stomach and places a series of full-thickness sutures along the greater curvature of the stomach, effectively reducing its size and creating a sleeve-like shape. This resembles what is achieved with surgical sleeve gastrectomy, but without removing any part of the stomach 3 4 5.

Pre-procedure Preparation

Before the ESG, patients undergo comprehensive evaluation, including medical history, physical exam, and sometimes imaging or laboratory tests. Fasting is required for 8–12 hours prior. The procedure is almost always outpatient, meaning patients arrive and leave the same day 3 4 5.

The ESG Technique

• Insertion: The endoscope is inserted through the mouth into the stomach.
• Suturing: Several rows of sutures are placed to create a narrowed, tubular gastric channel.
• No Incisions: No cuts are made in the abdomen, reducing the risk of wound complications.
• Completion: The scope and suturing device are removed, and patients are monitored for a short period 3 4.

Post-procedure and Follow-up

After the procedure, patients are observed for a few hours to ensure stability. Most are discharged the same day. Follow-up includes dietary counseling, medical monitoring, and routine endoscopic checks if indicated 11 15. Regular follow-ups are critical for maximizing weight loss and tracking for potential complications.

Benefits and Effectiveness of Esg

Choosing ESG can offer significant benefits for those struggling with obesity, especially for patients who are not ready or eligible for traditional surgery. ESG is more than just a weight-loss tool—it can also positively impact obesity-related health conditions.

Benefit	Description	Typical Outcome or Rate	Reference
Weight Loss	Significant TBWL and EWL over 12–24 months	15–17% TBWL, 53–59% EWL	1 2 3 11 12 15
Metabolic Improvement	Improved diabetes, blood pressure, lipids	Remission or improvement	2 15
Minimally Invasive	No abdominal incisions, outpatient	Lower complication risk	3 4 11 12
Durability	Sustained weight loss at 1–2 years	Maintained results	1 2 11 12

Table 2: Benefits and Effectiveness of ESG

Weight Loss Outcomes

ESG consistently delivers substantial weight loss. Across multiple studies, patients lost on average 15–17% of their total body weight (TBWL) at 12 months, with excess weight loss (EWL) rates around 53–59% 1 2 3 11 12 15. This degree of weight loss is considered clinically significant and is often sufficient to improve or resolve many obesity-related conditions.

Metabolic and Health Improvements

ESG’s benefits extend beyond the scale. Patients frequently see improvements in:

• Blood pressure
• Blood sugar (including remission of type 2 diabetes)
• Lipid profiles (cholesterol and triglycerides)
• Liver function (e.g., improvement in fatty liver disease) 2 15

Some studies report complete remission of diabetes, hypertension, and dyslipidemia in a notable percentage of patients within months after ESG 15.

Safety and Minimally Invasive Nature

Because ESG involves no external incisions, it's associated with less pain, faster recovery, and a lower risk of surgical wound complications. Most procedures are performed on an outpatient basis, with patients returning home the same day 3 4 11 12.

Durability of Results

Weight loss is maintained over at least 1–2 years in the majority of patients, with data showing only modest weight regain in some cases 1 2 11 12.

Risks and Side Effects of Esg

No medical procedure is risk-free, and ESG is no exception. However, its minimally invasive nature means risks are generally lower compared to surgical options. Understanding these risks helps you make an informed decision.

Risk	Frequency/Severity	Typical Management	Reference
Mild GI Symptoms	Nausea, vomiting, abdominal pain	Up to 92%, self-limited	4 15 11 12
Severe Events	Perigastric leak, bleeding, infection	1–2%, hospitalization	1 2 11 12 15
Pulmonary/Other	Embolism, pneumothorax (rare)	<0.5%, full recovery	1 15
Mortality	None reported in large series	N/A	11 15

Table 3: Risks and Side Effects of ESG

Common Side Effects

Most patients experience mild to moderate gastrointestinal symptoms such as:

• Nausea
• Vomiting
• Abdominal pain

These typically occur in the first week and are managed with medications. Over 90% of patients in some studies reported these symptoms, but they resolved quickly 4 15.

Serious Adverse Events

Serious complications are rare (1–2%). They include:

• Perigastric fluid collection or leak
• GI bleeding
• Infection
• Rare events like pulmonary embolism or pneumothorax

Most serious events are managed non-surgically. The risk of life-threatening complications is very low, and no deaths have been reported in large studies 1 2 11 12 15.

Long-term Risks

Unlike surgical sleeve gastrectomy, ESG rarely causes or worsens gastroesophageal reflux disease (GERD) 13. There is also a lower risk of long-term nutritional deficiencies since the stomach is preserved.

Recovery and Aftercare of Esg

Recovery from ESG is typically short and straightforward, but aftercare is crucial for lasting success. Knowing what to expect can help patients feel confident and supported.

Phase	Typical Duration	Key Actions	Reference
Immediate	4–6 hours observation	Monitor, manage symptoms	3 4 5 15
Short-term	1 week	Gradual reintroduction of diet	15
Long-term	Ongoing (months–years)	Nutrition, follow-up, support	1 4 11 15

Table 4: Recovery and Aftercare Stages

Immediate Recovery

After ESG, patients are monitored in a recovery area for several hours. Most can go home the same day. Pain, nausea, and discomfort are expected but typically mild and managed with medications 3 4 15.

Diet Progression

• First few days: Clear liquids only
• By 1 week: Progression to pureed and soft foods
• After 2–4 weeks: Transition to a regular healthy diet, focusing on portion control 15

Adherence to these dietary stages is key for healing and maximizing early weight loss.

Long-term Follow-up and Support

• Regular medical visits to monitor weight loss and health markers
• Access to nutritionists and behavioral counselors
• Monitoring for rare complications or nutritional deficiencies

Patients who engage in ongoing follow-up and support programs have superior outcomes 1 4 11 15.

Success Tips

• Commit to dietary changes and regular physical activity
• Attend all scheduled follow-up visits
• Seek support from health professionals and peers

Alternatives of Esg

While ESG offers an effective, minimally invasive pathway to weight loss, it's not the only option. Understanding alternatives helps patients and providers make the best individualized choice.

Alternative	Invasiveness	Weight Loss Potential	Reference
Laparoscopic Sleeve Gastrectomy (LSG)	Surgical	Higher than ESG	13
Gastric Balloon	Minimally invasive	Modest, temporary	11
Lifestyle Modification	Non-invasive	Variable, often less	2 11
Medications	Non-invasive	Mild–moderate	2 11

Table 5: Alternatives to ESG

Surgical Bariatric Procedures

Laparoscopic Sleeve Gastrectomy (LSG):

• Surgical removal of most of the stomach
• More total weight loss than ESG, but higher risk of complications
• Higher rates of new-onset GERD and longer recovery 13

Endoscopic Options

Gastric Balloon:

• Temporary placement of a balloon in the stomach
• Less weight loss than ESG; balloon removed after 6 months 11

Non-Procedure-Based Approaches

Lifestyle Modification:

• Diet, exercise, behavioral therapy
• Safest, but least effective for severe obesity 2 11

Medications:

• FDA-approved anti-obesity drugs
• Useful for select patients, but less effective than ESG or surgery 2 11

Which Option Is Right for You?

The best choice depends on:

• Degree of obesity
• Health status and comorbidities
• Previous weight-loss efforts
• Personal preferences and treatment goals

Patients with more severe obesity or those needing the most weight loss may benefit from surgical options, while those seeking a less invasive option with fewer risks may prefer ESG or endoscopic therapies 13.
