Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) in Punjab-Dr Amit Garg | Fortis Hospital (Mohali)

Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) in Punjab, also known as Mini gastric bypass surgery, is a mixed restrictive and malabsorptive weight loss procedure offered in Punjab, India. This surgical intervention involves creating a new, small gastric pouch and rearranging the digestive tract to limit food intake and reduce calorie absorption, resulting in significant and sustained weight loss.

During LRYGB, specialized stapling instruments are used to create a small 30 cc gastric pouch without removing the remaining stomach. The outlet of this pouch is connected to the small intestine, bypassing a portion of the intestine and redirecting digestive juices back into the common channel in a “Y” shape hookup, hence the name Roux-en-Y Gastric Bypass. This arrangement leads to early satiety, reduced appetite, and decreased calorie absorption, resulting in substantial weight loss ranging from 60% to 80% of excess weight over approximately 2 years.

Dr. Amit Garg , a leading weight loss surgeon in Punjab with over 10 years of experience, specializes in performing LRYGB. Dr. Garg’s expertise includes addressing severe reflux issues and controlling type 2 diabetes through modified Roux-en-Y Gastric Bypass, which has shown promising results in diabetes remission. Despite advancements in other procedures like gastric sleeve and mini gastric bypass, LRYGB remains a powerful and effective option for select patients with specific health concerns.

Candidate Criteria for Gastric Bypass Surgery

Ideal candidates for gastric bypass surgery in Punjab include individuals with a BMI greater than 40 kg/m² or a BMI ranging from 35 to 39.9 kg/m² with serious obesity-related health problems such as type 2 diabetes, hypertension, or severe sleep apnea.

Procedure Details and Recovery after Roux-en-Y or Gastric Bypass Surgery

LRYGB is performed laparoscopically under general anesthesia, with an approximate duration of 2 hours. Patients with BMI > 50 might require a pre surgery liquid diet in order to reduce the size of the left lobe of liver. For super obese patients, LRYGB might be difficult to perform and in these patients RYGB is done as a staged procedure. In the first stage gastric sleeve is done so that patients can lose 30-40 kgs of excess weight and then after 6 months gastric sleeve is converted into a gastric bypass so that patient can reach ideal weight.

During LRYGB, after port placements, the liver is retracted using Nathansons liver retractor. Lesser sac is opened at the level of the 2nd vessel on lesser curvature. Horizontal and then vertical staplers are fired in order to create a small stomach pouch of 30 cc. Ligament of Treitz is identified and 100 cm of small intestine is bypassed and connected to small stomach pouch . The intestine is divided using staplers proximal to the anastomosis and again connected to the distal intestine 100cm from gastrojejunostomy. Inter-mesenteric defect is closed and Petersons defect is closed to prevent formation of internal hernias using non absorbable sutures. A methylene blue dye leak test is done to check for leaks from Gastrojejunostomy. After achieving hemostasis, ports are closed.

Possible Risks and Complications of Gastric Bypass Surgery in Punjab

Like any abdominal surgery, LRYGB carries risks such as excessive bleeding, infection, leakage, bowel obstruction, dumping syndrome, gallstones, hernia, and malnutrition. However, with proper preoperative evaluation and postoperative care, these risks can be minimized, and patients can experience significant improvements in obesity-related conditions like gastroesophageal reflux disease, heart disease, hypertension, obstructive sleep apnea, and infertility.
