Upper Gastrointestinal Surgery

The surgical treatment of diseases of the gall bladder, liver and pancreas (hepatobiliary system) and oesophagus, stomach and small bowel (upper gastrointestinal tract) is performed by Gastro surgeon.

Following surgeries are included in upper GI

Bariatric Surgery

Bariatric surgery (weight loss surgery) is designed to treat severe obesity. Obese patients can achieve an accelerated weight loss through various bariatric surgery options; this is achieved by reducing the size of the stomach, for example using a gastric band or removing part of the stomach altogether.

How does bariatric surgery work?

This surgery alters the anatomy and function of the esophagus, stomach and small bowel to drastically reduce hunger and eating capacity. Once patients have had bariatric surgery they are able to more easily control their eating, lose weight and gain health. Following successful bariatric surgery most patients find that diseases such as diabetes, high blood pressure and sleep apnoea significantly improve or disappear altogether.


Upper gastrointestinal cancer (upper GI cancer) affects the gastrointestinal tract and organs that play accessory to digestion, such as esophagus, stomach, small intestine, biliary system and the pancreas.

Once symptoms of upper gastrointestinal (GI) cancer have been detected (symptoms will depend entirely on the affected organ, but can include difficulty swallowing caused by an obstruction) it is important to seek diagnosis and treatment immediately.

Once diagnosed, the treatment of upper GI cancer is dependent on the type and location of cancer. We are specialists in upper GI oncology (upper GI cancer treatment), and our patients have the reassurance of individualized treatment offered in a team environment.

Reflux and Swallowing Disorders

What causes reflux

Reflux occurs when gastric content leaves the stomach and moves up to irritate the oesophagus, voice-box or lungs. This is not something that is supposed to happen frequently in healthy people, and it occurs only when the pressure inside the stomach becomes greater than the pressure keeping the lower oesophagus closed.

Reflux and Swallowing Disorders:

The four main causes of reflux are:

Hiatus hernia

Weak lower esophageal sphincter (valve)

Oesophageal Sensitivity

Gastroparesis (paralysed stomach)

Hernia Treatment

Hernia treatment; hernias are defects in the abdominal wall that often cause pain, discomfort and unsightly cosmetic deformity. Typically caused by an organ pushing through an opening in the muscle or tissue that is designed to keep it in place.

The two most common hernia types are inguinal hernias and incisional hernias, but there are also umbilical hernias and hiatal hernias. If you suspect you may have a hernia you should seek medical advice; typically doctors can diagnose a hernia through a physical examination. However you may require X-rays or ultrasounds to detect small body wall hernias, and endoscopy (or other tests) to diagnose a hiatus hernia.

We often choose to perform laparoscopic surgery for hernia treatment (keyhole surgery), as it is associated with the lowest re-occurrence and infection rate.


Gastroscopy; the examination of the upper digestive tract using an endoscope (flexible tube containing a light and a camera) to view the lining of organs (esophagus, stomach and beginning of small bowel).

Gastroscopy is used to diagnose conditions such as stomach ulcers, cancers and reflux. A patient may require a gastroscopy following abdominal pain, vomiting or bleeding, to identify the problem.

Gastroscopies can also be used to deliver therapies that were once the realm of major open surgeries including treatment of gallstones, pancreatitis, Barrett’s oesophagus, cancers and achalasia.


Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure that combines upper gastrointestinal (GI) endoscopy and x-rays to treat problems of the bile and pancreatic ducts.

Using ERCP we can treat gallstones that have grown in the liver ducts, or fallen out of the gallbladder. ERCP can also be used to treat the causes of pancreatitis and can diagnose/start the treatment of pancreatic cancer, biliary cancer and duodenal cancer.
