Gastric Bypass Surgery

Gastric Bypass Surgery

Most of you might aware of this term in the recent times. This is becoming a popular treatment for weight loss. But, most times we are not getting proper insight about the most important and common surgical procedures like this. Here is an intro to you about the gastric bypass procedures.

What is this?

This is a procedure that would first divide the stomach into two parts namely: small upper pouch and larger remnant pouch. Then, the small intestines would be re-arranged in order to connect these two parts. 

To your surprise, surgeons have come up with several different ways for reconnecting the intestine, thereby leading to several different names for gastric bypass surgery.

What does it do?

Any of the gastric bypass surgery will lead to a marked decrease in the functional volume of the patient’s stomach which would be accompanied by altered physiological as well as physical responses to the food. 

To whom it is prescribed?

The gastric bypass surgery will be prescribed for the patients in order to treat the following conditions:

  • Morbid Obesity
  • Type 2 Diabetes
  • Hypertension
  • Sleep apnea
  • Other comorbid conditions

It is to be noted that the consensus panel of National Institutes of Health has recommended the following criteria in order to consider for the gastric bypass surgeries:

 People with BMI 40 and above

People with BMI 35 with one or more comorbidities.

What are the Techniques Adopted?

As you may see that gastric bypass surgeries are contributing a large majority of the bariatric procedures that are being performed. And, a large number of operations are being performed by laparoscopy techniques. 

A laparoscopic operation would be performed using many small incisions and the surgeon would view his operation on a video screen. The Roux-en-Y laparoscopic gastric bypass is the first and most difficult procedures performed.

Variations in Gastric Bypass:

There are three major variations followed in gastric bypass which are:

  • Gastric bypass, Roux-en-Y (proximal)
  • Gastric bypass, Roux-en-Y (distal)
  • Mini-gastric bypass

What Happens After Gastric Bypass?

A gastric bypass surgery will be able to reduce the stomach size well more than 90%. The gastric bypass pouch would have been formed from the part of the stomach and is least susceptible to stretch. 

This would prevent any significant long-term change in the volume of the pouch. When the patient is first ingesting a small amount of food, the response would be stretching of wall of the pouch. 

This would stimulate the nerves telling the brain that the stomach is full. Thus, the patient would have a sensation of fullness.

Is there any Complication Associated with this Procedure?

Yes, as with all kinds of surgery, complications might occur with gastric bypass surgery also. As such, the overall complication rate during a 30-day time post surgery would range from 7% (laparoscopic procedures) to 14.5% (open incisions). Some of the complications of gastric bypass surgery are:

  •  Infection
  •  Venous thromboembolism
  •  Hemorrhage
  •  Hernia
  •  Bowel obstruction
  •  Anastomotic leakage
  •  Anastomotic stricture
  •  Anastomotic ulcer
  •  Dumping syndrome

What are the health benefits of gastric bypass?

One can experience the weight loss of 65 to 80% of excess body weight as a result of the gastric bypass surgery. What more? There will be a significant reduction in comorbid conditions as well:

  • Hyperlipidemia will be corrected.
  • Essential hypertension will be relieved.
  • Obstructive sleep apnea will be improved.
  • Type 2 diabetes will be reversed.
  • Gastroesophageal reflux disease will be relieved.
  • Signs of venous thromboembolic reflux disease will be alleviated.
  • Lower back pain and joint pains will be relieved.

Moreover, almost all the patients will be able to enjoy larger participation in their family and social events.
