Why Obesity Surgery?


People who have struggled for many years with the illnesses and discomforts related to severe obesity often give up hope. They know what it is like to persevere time and again with diets and programs that fail to deliver long-term results. Nonetheless, giving up is not an option. Their lives depend on successfully treating obesity and maintaining a healthy weight throughout life. If you are someone for whom non-surgical procedures have failed to provide sustained weight loss, you can be evaluated for, and if appropriate, undergo lifesaving bariatric surgery. In cases of severe obesity, bariatric surgery is the only proven method of achieving long-term weight control.

Our multidisciplinary team of bariatric experts will see you through the entire process. We will make certain that you are prepared for surgery, both physically and psychologically, and we will provide the most advanced and current procedures that are right for you. After surgery, we will assist you in committing to the lifestyle changes that will assure optimal success.

What are the surgical options:

  • Laparoscopic Sleeve Gastrectomy
  • Laparoscopic Roux-en-Y Gastric Bypass
  • Laparoscopic Adjustable Gastric banding
  • Robotic Bariatric Surgery (Using the latest da Vinci Si HD Robotic system)

With the advent of latest technology and skills, patients now get a minimally invasive advantage of key hole surgery leading to fast recovery, less pain, better cosmesis, small scars and early return to work.

Types of Bariatric Surgery:

Laparoscopic / Robotic Sleeve Gastrectomy

In this restricive procedure, the capacity of stomach is reduced to approximately 100ml, so the patient feels full early during a meal. It also shifts the hormonal balance so he/she feels less hungry between meals.

In LSG, the stomach is divided along the greater curvature to create a 60-100 ml sleeve of stomach using endoscopic staplers. The staple line is always oversewn for extra security and safety to prevent any leak or bleed from staple line. The integrity of the pouch is checked using per-operative gastroscopy. The excised portion of stomach is removed in a plastic bag. A small abdominal drain is usually left which is taken out after 48-72 hours.

In our own series of patients who underwent LSG, there is a weight loss to the tune of 70-95% of excess body weight. Resolution of Diabetes occurred in 78.94%, resolution of HTN occurred in 72%, and OSA improved in 93% patients. Mean Quality of life index improved from 2.7 to 8.2 (out of 10).

Laparoscopic / Robotic Roux-n-Y Gastric Bypass (LRYGB)

It is also an effective procedure for resolution of diabetes, sleep apnea and control of hypertension. In this, a small gastric pouch of 15-20ml is created, which a reduction of food intake at a time. The intestinal architecture is then changed so that a large portion (175-250cm) of small intestine is bypassed, before the digestion and absorption of food starts. This results in malabsorption of food, and subsequent drastic weight loss. In the end, the integrity of pouch is checked using per-operative gastroscopy. A small abdominal drain is usually left which is taken out after 48-96 hours

What do I expect after surgery?

After the surgery, the patient is kept overnight under close observation. Next day, the patient is started on a clear liquid diet after doing a contrast X-ray study, and shifted to room. He/she is encouraged to walk and do all routine activities.

He/she is discharged on the third or fourth day of surgery depending on the comfort of the patient and amount of oral intake. A detailed and properly explained discharge summary is given to the patient along with a diet chart.

First follow-up visit is after seven days and then at 1 month, 3 months, 6 months, 1 year and yearly thereafter. The patients are encouraged to exercise and do maximum physical activity. One can expect an excess body weight loss to the tune of 70-95 % depending on the procedure and compliance of the patient with the instructions. A long term dietary supplementation is usually required with RYGB but not so with LSG.

Every Surgery Has Risks

All surgical procedures carry risks, even more so when a patient is obese. Different procedures involve different risks, and depending upon your individual circumstances, your risks may be higher or lower than average. Keep in mind that in a hospital with a team of doctors from various specialities and huge experience in bariatric surgery, the complication and mortality rates will be lower. Your surgeon will discuss potential risks of surgery with you so you can make an educated and informed decision.
