Description

Jason Robertson is a New Zealand trained general surgeon specialising in Upper Gastrointestinal, Bariatric and Laparoscopic surgery. Jason is a consultant surgeon at Waitemata District Health Board as well as in private practice.

Referral

Referral Expectations

When you come to your appointment, your surgeon will ask questions about your illness and examine you to try to determine or confirm the diagnosis. This process may also require a number of tests (e.g. blood tests, x-rays, scans etc). Sometimes this can all be done during one visit, but for some conditions this will take several follow-up appointments. Occasionally some tests are arranged even before your appointment to try to speed up the process.
 
Once a diagnosis has been made, your surgeon will discuss treatment with you. In some instances this will mean surgery, while other cases can be managed with medication and advice. If surgery is advised, the steps involved in the surgical process and the likely outcome are usually discussed with you at this time.

Procedures / Treatments

Gastrointestinal Disorders

Conditions of the gut dealt with by general surgery include disorders of the oesophagus, stomach, small bowel, large bowel and anus. These range from complex conditions such as ulceration or cancer in the bowel through to fairly minor conditions such as haemorrhoids. Many of the more major conditions such as bowel cancer will require surgery, or sometimes treatment with medication, chemotherapy or radiotherapy. Haemorrhoids are a condition where the veins under the lining of the anus are congested and enlarged. Less severe haemorrhoids can be managed with simple treatments such as injection or banding which can be performed in the clinic while larger ones will require surgery.

Anti-reflux Surgery

Gastro-oesophageal Reflux Disease (GERD) occurs when the valve between the stomach and the lower end of the oesophagus is not working properly. Laparoscopic Nissen Fundoplication is a surgical procedure for GERD that involves wrapping the top part of the stomach (fundus) around the lower end of the oesophagus. The valve between the stomach and the oesophagus is also replaced or repaired.

Bariatric Surgery

Bariatric or weight loss surgery refers to a number of different procedures that can be performed to treat obesity. Procedures fall into three main types: Malabsorptive - these procedures involve bypassing a section of the small intestine thus reducing the amount of food absorbed into the body. Restrictive - these procedures involve reducing the size of the stomach, usually by creating a small pouch at the top of the stomach which limits the amount of food that can be eaten. Malabsorptive/Restrictive Combination - these procedures combine both techniques e.g. gastric bypass surgery in which a small stomach pouch is formed and its outlet connected to part of the small intestine.

Gallstones

General surgery covers some disorders of the liver and biliary system. The most common of these is pain caused by gallstones. These are formed if the gallbladder is not working properly, and the standard treatment is to remove the gallbladder (cholecystectomy). This procedure is usually performed using a laparoscopic (keyhole) approach.

Gastrectomy

Partial: the diseased part of the stomach is removed and the remaining section is reattached to the oesophagus (food pipe) or small intestine. Total: all of the stomach is removed and the oesophagus is attached directly to the small intestine.

Hernias

A hernia exists where part of the abdominal wall is weakened, and the contents of the abdomen push through to the outside. This is most commonly seen in the groin area but can occur in other places. Surgical treatment is usually quite straightforward and involves returning the abdominal contents to the inside and then reinforcing the abdominal wall in some way.

Gastroscopy

A long, flexible tube with a tiny camera attached (gastroscope) is inserted through your mouth and moved down your digestive tract. This allows the surgeon a view of the upper part of your digestive tract i.e. oesophagus (food pipe), stomach and duodenum (top section of the small intestine). Sometimes a biopsy (small tissue sample) will need to be taken during the procedure for later examination at a laboratory.
