How is Sleeve Gastrectomy Surgery Performed?

Sleeve gastrectomy, also known as gastric sleeve surgery, is a surgical weight loss procedure that involves the following steps:

  1. Anesthesia: The patient is placed under general anesthesia, ensuring they are asleep and pain-free during the procedure.
  2. Laparoscopic Approach: Most sleeve gastrectomies are performed using a laparoscopic approach, where small incisions are made in the abdomen.
  3. Removal of a Portion of the Stomach: Using specialized surgical instruments, the surgeon removes approximately 80-85% of the stomach. The remaining portion is shaped like a sleeve or a banana.
  4. Stapling: The surgeon uses surgical staplers to close the incisions and create the new smaller stomach pouch. The removed portion of the stomach is then taken out of the body.
  5. Complete the Procedure: The surgery is completed by ensuring there are no leaks or bleeding, and the incisions are closed with sutures or surgical glue.
  6. Hospital Stay: After the surgery, the patient is monitored in the hospital for a few days to ensure a smooth recovery.

Sleeve gastrectomy works by reducing the stomach’s capacity, restricting food intake, and reducing hunger hormones, resulting in significant weight loss over time. This procedure is less invasive than traditional open surgery, leading to shorter recovery times and reduced risk of complications. It is essential for patients to follow their surgeon’s post-operative instructions, adopt a healthy lifestyle, and attend regular follow-up visits to support their weight loss journey after sleeve gastrectomy.

What are Sleeve Gastrectomy Methods?

Sleeve gastrectomy, also known as gastric sleeve surgery, is primarily performed using laparoscopic techniques. There are no specific alternative methods for the procedure; however, variations in surgical approaches and techniques may exist based on the surgeon’s expertise and the patient’s specific condition. The main methods for sleeve gastrectomy include:

  1. Laparoscopic Sleeve Gastrectomy (LSG): This is the most common and preferred method. It involves making several small incisions in the abdomen and using a laparoscope (a thin, lighted tube with a camera) and specialized surgical instruments to remove a portion of the stomach and create a sleeve-like structure.
  2. Single Incision Sleeve Gastrectomy: Some surgeons may perform the procedure through a single incision, typically in the belly button, using specialized tools designed for single-port surgery. This method aims to reduce visible scarring.
  3. Robotic Sleeve Gastrectomy: In this approach, robotic-assisted surgical technology is utilized to enhance the surgeon’s precision and control during the procedure. Robotic surgery may be considered in select cases where advanced technology is available and appropriate.

Regardless of the method used, the main goal of sleeve gastrectomy remains the same: to reduce the stomach’s size and promote weight loss by restricting food intake. Patients should discuss with their surgeon the specific approach planned for their sleeve gastrectomy and address any concerns before undergoing the procedure.

Who Is Sleeve Gastrectomy Suitable For?

Sleeve gastrectomy, or gastric sleeve surgery, is generally considered suitable for individuals who meet the following criteria:

  1. BMI Criteria: Candidates typically have a body mass index (BMI) of 40 or higher, indicating severe obesity, or a BMI between 35 and 39.9 with obesity-related health conditions, such as type 2 diabetes, high blood pressure, or sleep apnea.
  2. Failed Weight Loss Attempts: Candidates should have attempted and failed to achieve significant weight loss through other non-surgical methods, such as diet, exercise, and lifestyle changes.
  3. Health Conditions: Individuals with obesity-related health conditions that could improve with weight loss may also be considered suitable candidates.
  4. Commitment to Lifestyle Changes: Candidates should be committed to making significant lifestyle changes after the surgery, including adopting a healthier diet and regular exercise.
  5. No Contradicting Health Conditions: Candidates should not have any health conditions that would increase the risks associated with surgery.
  6. Psychological Evaluation: A psychological evaluation may be conducted to assess the candidate’s mental health and emotional readiness for the surgery and post-operative lifestyle changes.

Each case is unique, and a thorough evaluation by a qualified healthcare professional is necessary to determine the suitability of sleeve gastrectomy for an individual’s specific medical condition and weight loss goals. The decision to undergo gastric sleeve surgery should be a well-informed one, and patients should have a clear understanding of the risks and benefits associated with the procedure.

What is the Sleeve Gastrectomy Pre-treatment Procedure?

Before undergoing a sleeve gastrectomy, patients typically undergo several pre-treatment steps and evaluations to ensure the procedure’s safety and effectiveness. Some common pre-treatment measures include:

  1. Medical Evaluation: A comprehensive medical evaluation is conducted to assess the patient’s overall health and any existing medical conditions that may affect the surgery.
  2. Nutritional Counseling: Patients may receive nutritional counseling to learn about dietary changes and healthy eating habits that will be crucial after the surgery.
  3. Weight Loss Attempts: Some healthcare providers may require patients to demonstrate previous attempts at weight loss through diet, exercise, and other non-surgical methods before proceeding with sleeve gastrectomy.
  4. Lifestyle Changes: Patients are encouraged to adopt healthier lifestyle habits, including regular exercise and quitting smoking if applicable.
  5. Psychological Evaluation: A psychological assessment may be conducted to assess the patient’s mental health and emotional readiness for the surgery and the post-operative lifestyle changes.
  6. Education: Patients are provided with educational materials and sessions to fully understand the surgery’s risks, benefits, and expected outcomes.
  7. Pre-operative Testing: Patients may undergo various pre-operative tests, such as blood tests, imaging studies, and electrocardiograms, to ensure they are in optimal condition for the surgery.

These pre-treatment steps are essential to ensure that the patient is well-prepared for the sleeve gastrectomy and to maximize the chances of a successful outcome. It is crucial for patients to actively participate in their pre-treatment process and follow their healthcare provider’s guidance for a safe and effective surgery.

Treatment Process After Sleeve Gastrectomy Surgery

The post-operative treatment process after sleeve gastrectomy is crucial for a successful recovery and long-term weight loss. Here are some key aspects of the post-treatment care:

  1. Hospital Stay: After the surgery, patients typically stay in the hospital for a few days to recover and be monitored by healthcare professionals.
  2. Pain Management: Pain medications may be prescribed to manage any discomfort or pain experienced after the surgery.
  3. Liquid Diet: In the initial days after the surgery, patients will be on a liquid diet, gradually progressing to soft foods and then solid foods as tolerated.
  4. Physical Activity: Patients are encouraged to start light physical activity, such as walking, as soon as possible after the surgery to aid in the recovery process.
  5. Follow-up Visits: Regular follow-up visits with the healthcare provider are scheduled to monitor the patient’s progress, address any concerns, and provide support throughout the weight loss journey.
  6. Dietary Guidance: Patients receive dietary guidance from a nutritionist or dietitian to ensure they are consuming the right nutrients and following a balanced diet to support weight loss and overall health.
  7. Lifestyle Changes: Long-term success after sleeve gastrectomy depends on adopting healthier lifestyle habits, including regular exercise and making healthier food choices.
  8. Support: Emotional support and counseling may be provided to help patients cope with the physical and emotional challenges of weight loss and lifestyle changes.

Patients should closely follow their healthcare provider’s instructions during the post-operative period to achieve the best possible results and maintain weight loss over time. Regular communication with the healthcare team is essential for addressing any concerns and ensuring a smooth recovery process.
