    • Bypass of the section of the small intestine (duodenum) is done to attach smaller stomach to middle of small intestine to absorb the most calories
    • As stomach is smaller and absorb fewer calories, patients eat less. Even, food does not travel through duodenum
  • Laparoscopic Adjustable Gastric Banding
    • Upper part of stomach is wrapped with silicone band filled with saline to create small pouch and cause restriction
    • Patients eat less as the feeling of full is quite quick
    • By adding or removing saline from band after surgery, the size of restriction can be adjusted
  • Vertical Sleeve Gastrectomy
    • Emerging procedure
    • A sleeve-shaped stomach is left behind after removing approximately 85% of the stomach
    • No published studies on long-term results

  • According to study, bariatric surgery resolves type 2 diabetes in 73% - 83% of patients

  • According to long-term studies, morbidly obese patients who had surgery maintain a greater weight loss and more favorable levels of diabetes, cholesterol and hypertension up to 10-14 years after surgery when compared to those who did not have surgery

Sleeve gastrectomy
  • With the increase in obesity rates, adolescents (12-17 years old) who are receiving bariatric surgery are also increasing
  • Bariatric surgery is the most common procedure performed on morbidly obese adolescents of more than 10 years and for this age group, doctors are gaining experience in surgery
  • The long-term efficacy and impact of the surgery is a topic of ongoing research

  • Bariatric surgery is regarded as a tool to help morbidly obese patients in losing weight. It is effective only when used in conjunction with some changes in eating and exercise habits
  • Keeping regular appointments with the doctors is also beneficial, as research shows that bariatric surgery patients who keep all doctor's appointments for at least 3 years after surgery lost an average of 24% more weight, as compared to those who skipped appointments
  • According to a study, in comparison to patients who do not attend support groups, bariatric surgery patients who attend support groups maintain about 20% - 30% greater excess weight loss

GI Bleeding Surgery

GI Bleeding Surgery

Surgical treatment is recommended for patients who present with intermittent vomiting of blood or passing malena for a permanent cure for bleeding. In non-cirrhotic patients, the surgery is performed in the form of a splenorenal shunt or splenectomy with devascularisation in cirrhotic patients. The patients who bleed from a duodenal ulcer will be considered as emergency case and require under-running of the bleeder or a partial gastrectomy.

On-time surgery done properly without any delay can save many lives.

In both national and international front, Dr.Radhakrishna has presented his experience, including Asia-Pacific Hepato-biliary conference in Bangkok and Digestive Diseases Week at New Orleans, USA in 2010.
