FREQUENTLY ASKED QUESTIONS

What is gastrointestinal surgery?

Gastrointestinal surgery is a branch of surgery focused on the diagnosis, treatment, and surgical management of conditions affecting the digestive tract, including the oesophagus, stomach, small intestine, colon, rectum, liver, pancreas, and gallbladder.

What conditions are treated by a gastrointestinal surgeon?

Gastrointestinal surgeons treat conditions such as digestive tract cancers (stomach, colon, oesophagus), ulcers, gastrointestinal bleeding, bowel obstruction, inflammatory bowel disease, hernias, and polyps, among others.

What types of procedures are commonly performed in gastrointestinal surgery?

Standard procedures include tumour removal, resection of affected sections of the digestive tract, minimally invasive laparoscopic surgery, endoscopic procedures, hemorrhoidectomy, and surgeries for gallstones or appendicitis.

What is minimally invasive or laparoscopic gastrointestinal surgery?

Minimally invasive surgery involves using small incisions, cameras, and specialised instruments to perform surgeries with reduced recovery time, less pain, and minimal scarring compared to traditional open surgery.

How should patients prepare for gastrointestinal surgery?

Preparation may include preoperative consultations, blood tests, imaging studies, bowel preparation if necessary, and fasting for a specific period before surgery.

What is the recovery time after gastrointestinal surgery?

Recovery time varies depending on the procedure and patient health but typically ranges from a few days for minor procedures to several weeks for major surgeries. Minimally invasive procedures usually have shorter recovery periods.

Can gastrointestinal surgeons manage digestive cancers?
