Roux en Y Gastric Bypass, or stomach bypass, is considered by obesity experts to be the gold standard of modern bariatric surgery, and the benchmark for other bariatric procedures. Dr. Shashank Shah' Laparo Obeso Centre, Pune ::: Oxford of India ::

Combined Restrictive and Malabsorptive procedure

Roux-en Y Gastric bypass (RYGBP)

Known as the gold standard for Bariatric procedure. Creation of a small proximal pouch of the stomach ( around 15 to 30 cc ) to which a Roux limb of jejunum is anastomosed.

In four randomized prospective trials and three retrospective studies, RYGBP was found to induce significantly greater weight loss than did VBGP. ( 13,14,15 ) This was particularly true for patients addicted to sweets. “Sweet eaters” were found to lose weight more after RYGBP because most patients develop dumping syndrome symptoms after the ingestion of foods rich in sugar following RYGBP.

Currently the Dr. Shah performs LGBP by constructing a small gastric pouch of 15 to 30 ml with Biliopancreatic limb of the length of 50 to 80 cm and alimentary limb from 100 to 150 cm. The stoma is restricted to around 1cm.Following different techniques may be used :

Anticolic antigastric
Anticolic retrogastric
Retrocolic retrogastric

The GBP is associated with long – lasting weight loss in the vast majority of patients. The average weight loss is 66% of excess weight at the end of two years and 60% at the end of 5 years and 50% at the end of 10 years after surgery.

Gastric procedure for morbid obesity can yield dramatic and long term satisfactory weight reduction, with an average loss of two – thirds of excess weight within 1 to 2 years after GBP. Weight becomes stable at this level in most patients as the reduced caloric intake meets the caloric expenditure.
