Surgical Treatments

Laparoscopic Roux-en-Y Gastric Bypass (RYGB) is a weight-loss surgery that creates a smaller stomach pouch and attaches directly to the small intestine, limiting food intake and absorption.

Benefits include weight loss and improvements in obesity-related conditions like type 2 diabetes. However, risks can include infections and nutritional deficiencies. Adhering to a structured diet and regular follow-up care will help ensure a successful recovery.

This procedure is effective for weight management but demands a commitment to a healthy lifestyle.

Robotic Roux-en-Y Gastric Bypass (RYGB) is a minimally invasive weight-loss surgery that employs robotic assistance for greater precision. A small pouch is created with the stomach which is connected to a section of the small intestine.

Benefits include enhanced precision, shorter recovery times, and lower complication risks, while potential risks involve infection and nutritional deficiencies. For a successful recovery, it is imperative to follow a structured post-operative diet and follow-up care.

This procedure gives you the advantages of a tradition RYGB and the advances of robotic technology.

Laparoscopic Sleeve Gastrectomy (LSG) is a minimally invasive weight-loss surgery that removes approximately 80% of the stomach, creating a sleeve-shaped pouch. This procedure helps limit food intake and reduces hunger hormones, resulting in significant and life-changing weight loss.

LSG involves making small incisions. Risks are mitigated with a smaller incision compared larger ones and more complex surgeries since there is no rerouting of the intestines. Recovery involves a structured diet and regular follow-up care with your healthcare provider.

LSG is effective for managing obesity, providing hope and motivation for a healthier future.

Robotic Sleeve Gastrectomy (RSG) is a minimally invasive bariatric procedure where a robotic system assists in removing up to 80% of the stomach, forming the organ into the shape of a sleeve.

A smaller stomach promotes weight loss due to less hunger and food intake. Fewer complications, greater precision, and a quicker recovery time are advantages of the use of robotics.

This procedure advances the laparoscopic approach, including cutting-edge technology to improve safety, precision, and recovery.

Duodenal-Jejunal Bypass with Sleeve Gastrectomy (DJB-SG) is a bariatric surgery that combines sleeve gastrectomy (removing a large portion of the stomach) and duodenal-jejunal bypass (bypassing the first part of the small intestine).

This method promotes significant weight loss and can improve the management of type 2 diabetes while lowering the risk of dumping syndrome. Nutritional supplements will be required for life even though metabolic benefits and less malabsorption are benefits of this procedure.

DJB-SG may be suitable for those considering weight loss and diabetes management.

Laparoscopic Duodenal Switch (DS) combines two surgeries, such as stomach reduction and intestinal bypass. DS promotes significant weight loss and improves type 2 diabetes.

Patients limit food intake and nutrient absorption with the procedure, offering long-term weight loss and diabetes remission. There are risks of nutritional deficiencies, which require lifelong supplementation. More complex surgeries are a possibility, with potential complications.

DS is generally recommended for patients with severe obesity and metabolic issues.

Single Anastomosis Duodeno-Ileostomy (SADI) is a bariatric surgery that is highly effective in promoting significant weight loss and improving type 2 diabetes.

By combining a sleeve gastrectomy with a single bypass connection between the duodenum and ileum, SADI reduces food intake and nutrient absorption. It simplifies the more complex duodenal switch, resulting in shorter surgery and fewer risks.

While it is effective, it requires lifelong vitamin supplementation and can cause changes in bowel habits.
