FAQs

What are the benefits of laparoscopic (keyhole) surgery? 

Laparoscopic surgery, often called keyhole surgery, involves performing operations through small incisions rather than a single large incision. The primary benefits include significantly reduced post-operative pain, smaller scars, a lower risk of infection, and a faster return to normal activities and work.
Dr Howard Fan specialises in laparoscopic hernia, gallbladder, and bowel surgery. 

How long is the recovery after keyhole surgery? 

While recovery varies by procedure, most patients undergoing laparoscopic surgery can return home the same day, or by the next day. Light activities can usually resume within a few days.  

Do I really need my gallbladder removed if I have gallstones?

It depends. Gallbladder removal (cholecystectomy) is recommended if gallstones are causing symptoms like biliary colic (abdominal pain), inflammation, or jaundice. If left untreated, symptomatic gallstones can lead to serious complications such as pancreatitis or bile duct infections. Because the gallbladder is a non-essential organ, its removal generally has no long-term impact on digestion for most patients. However, if you have no symptoms, it is not always necessary to remove your gallbladder. Consider a consultation with Dr Howard Fan to discuss your specific situation. 

What can I eat after gallbladder surgery? 

Most people can return to a normal diet. However, if you are having diarrhoea, consider a low-fat diet for the first few weeks to allow the digestive system to adjust. This is because bile that is normally stored in the gallbladder is used to help digest fats/oils, and without the gallbladder, the ability to digest fats/oils are diminished. Gradually reintroducing fats/oils helps prevent temporary digestive discomfort or bloating. 

Will a hernia go away on its own without surgery? 

No. Having a hernia is like having a hole in the wall. The hole does not cover itself. Likewise a hernia is a mechanical defect in the abdominal wall that cannot heal itself. While some hernias are painless, they typically increase in size over time. Surgery is recommended if you are having symptoms of pain or the hernia is getting larger. Urgent surgery is required if important structures, such as the bowel, are stuck in the hernia. 

What is the difference between a gastroscopy and a colonoscopy? 

A gastroscopy examines the upper digestive tract (oesophagus, stomach, and duodenum) via the mouth, while a colonoscopy examines the large bowel via the rectum. Both are day procedures performed under light sedation. Dr. Howard Fan (GESA accredited) uses these endoscopic techniques to investigate symptoms like reflux, abdominal pain, or changes in bowel habits.
