Gastro-Intestinal Surgery

The gastro-intestinal (GI) system is an important organ system, associated with digestion, absorption and excretion of food. There are a number of conditions which may affect the normal functioning of the GI system. Gastro-intestinal surgery is a surgical subspecialty, which involves the treatment of diseases and injuries of the gastro-intestinal tract.

Dr Richardson has broad experience in many aspects of gastro-intestinal surgery. Some of the procedures which he commonly performs include:

Stomach and oesophageal tumours (see Gastro-Oesophageal Cancer).

Hepato-biliary and pancreatic surgery (see Hepato-Biliary and Pancreatic Surgery)

Small bowel tumours – these tumours are rare and include cancers as well as neuroendocrine tumours (see Neuroendocrine Tumours). Surgery may involve removal of the tumour and the involved bowel as well as the associated lymph nodes.

Surgery for bowel obstruction – there are a number of causes for bowel obstruction. The small bowel is most commonly obstructed because of adhesions related to previous surgery. Surgery is sometimes required to relieve the obstruction.

Appendicectomy (Appendectomy) can be performed either by a small incision in the lower part of the abdomen or by keyhole surgery. It is a relatively common condition (see Appendicitis).

Gallbladder problems (see Gallstones, Laparoscopic Cholecystectomy, Gallbladder Cancer)

Colon resection – colectomy is the surgical resection of part of the large intestine and it is most often required for cancer involving the large bowel. It is performed under general anaesthesia and is done either by open surgery or by keyhole techniques.
