Gallbladder Removal Surgery in Christchurch

If your GP has referred you for gallbladder removal surgery, it's natural to have a lot of questions. Will it hurt? How long will I be off work? And — the one almost everyone asks — can I actually live without my gallbladder?

The short answer to that last one: yes, and most people do so without any issues at all.

Here's everything you need to know, in plain language.

What Is Gallbladder Removal Surgery?

Gallbladder removal surgery — known medically as a cholecystectomy — is one of the most commonly performed operations in New Zealand. It involves removing the gallbladder, a small pear-shaped organ that sits under your liver on the right side of your abdomen.

The gallbladder's job is to store bile, a fluid your liver produces to help digest fats. When gallstones form inside it — or when the gallbladder becomes inflamed or stops working properly — it can cause significant pain and health problems. Removing it is usually the most effective and permanent solution.

Why Would Someone Need Their Gallbladder Removed?

The most common reason is gallstones. These hard deposits can form when bile contains too much cholesterol or bilirubin, and they range in size from a grain of sand to a golf ball.

Gallstones don't always cause symptoms — but when they do, it's usually hard to ignore. The pain typically comes on suddenly in the upper right abdomen, often after eating a fatty meal, and can radiate to the back or shoulder. Some people also experience nausea, vomiting, or fever.

Other reasons for gallbladder removal include a chronically inflamed or poorly functioning gallbladder, or complications like stones that have migrated into the bile duct.

How Is the Surgery Performed?

Most gallbladder removal surgery is done laparoscopically — which means keyhole surgery. Instead of a large incision, the surgeon makes three or four small cuts (usually under a centimetre each) and uses a tiny camera and specialised instruments to remove the gallbladder.

Here's how it works:

• You'll be under general anaesthetic for the procedure
• Carbon dioxide gas is used to gently inflate the abdomen, creating space for the surgeon to work
• A small camera (laparoscope) is inserted so the surgeon can see everything clearly on a screen
• The gallbladder is carefully separated from the liver and bile duct, then removed through one of the small incisions
• The whole procedure typically takes 45 minutes to an hour

In a small number of cases — usually when there's significant inflammation, scarring, or an unusual anatomy — the surgeon may need to convert to an open procedure using a larger incision. This is always a patient-safety decision, not a complication.

What Happens After the Surgery?

Most people go home the same day or the following morning. Recovery is generally straightforward.

For the first week or two, you can expect:

• Some soreness around the small incision sites
• Mild fatigue — your body has had an operation, even if the cuts are small
• Shoulder or upper back discomfort from the gas used during surgery (this usually settles within a day or two)

Most people are back to light activity within a week and returning to desk-based work within one to two weeks. If your job involves physical labour, your surgeon will give you a more specific timeframe.

You'll receive clear written instructions about what to eat, any medications, and what to watch out for before you leave.

Can You Live a Normal Life Without a Gallbladder?

Yes — and the vast majority of people do. The gallbladder stores bile, but your liver continues producing it after the gallbladder is removed. Bile simply flows directly from the liver into the small intestine rather than being stored first.

For most people, this adjustment happens without any noticeable difference to daily life. A small number of people notice looser stools or digestive sensitivity to very fatty foods in the weeks after surgery — this usually settles as the body adapts, and can often be managed with simple dietary adjustments.

Long-term complications are uncommon, and for the overwhelming majority of patients, quality of life improves significantly once the gallbladder — and the pain it was causing — is gone.

What About the Referral Process?

In New Zealand, most people are referred to a surgical specialist by their GP after a diagnosis of gallstones or gallbladder disease — often following an ultrasound. Some people are referred after an episode of acute pain or an emergency admission.

At Canterbury Surgical Specialists, we see patients both through private referral and on recommendation from hospital colleagues. Your first appointment will be a consultation where we review your history, imaging, and symptoms, and discuss whether surgery is the right option for you — and if so, what the timing looks like.

There's no obligation to proceed, and we'll make sure you have all the information you need to make a confident, informed decision.

Quick Answers: Gallbladder Removal FAQs

How long does gallbladder surgery take? Most laparoscopic procedures take 45 minutes to an hour.

Will I be in hospital overnight? Usually not — most patients go home the same day or the morning after.

How long is recovery after gallbladder removal? Most people return to light activity within one week and desk work within two weeks.

Will I need a special diet after surgery? A low-fat diet is recommended for the first few weeks. Most people return to a normal diet over time.

Can gallstones come back after the gallbladder is removed? No — once the gallbladder is removed, gallstones cannot reform there. Stones can occasionally develop in the bile duct, but this is uncommon.

Is keyhole surgery safe? Laparoscopic cholecystectomy is one of the most well-established and commonly performed operations in the world. Your surgeon will discuss any specific risks with you at your consultation.
