Gallstones Surgery - Cholecystectomy
What is Gallstones Surgery?
Gallstones surgery is actually gallbladder surgery. It is medically known as cholecystectomy and is the surgical removal of the gallbladder—the small organ under the liver where gallstones can form.
This is the definitive treatment for symptomatic gallstones and is one of the most commonly performed operations worldwide.
The operation eliminates pain from gallstones, prevents life-threatening complications like pancreatitis or infection, and allows patients to return to a normal, healthy life without their gallbladder.
Key Facts About Gallstones Surgery
- The best option: Once the gallbladder is removed, the problem is almost always permanently solved.
- Minimally invasive is standard: Almost 99% of surgeries are performed laparoscopically (“keyhole”), resulting in less pain and faster recovery.
- Same-day or short stay: Most patients go home the same day or after one night in the hospital.
- You can live normally without a gallbladder: Your liver continues to produce bile, which flows directly into your intestine. Most people notice no long-term digestive issues.
- Highly effective: The surgery successfully resolves symptoms for almost all patients.
Common Types of Gallbladder Surgery
Laparoscopic Cholecystectomy (Keyhole Surgery)
- The gold standard: 4 small incisions (5-10mm each).
- Procedure: A tiny camera and specialized instruments are inserted to remove the gallbladder.
- Benefits: Minimal scarring, less post-operative pain, faster return to work and normal activities.
- Hospital stay: Often same-day discharge or an overnight stay.
Robotic-Assisted Cholecystectomy
- Advanced minimally invasive: Similar to laparoscopic but using a robotic system for enhanced 3D vision and precision.
- Best for: Complex cases, severe inflammation, or anatomical variations.
- Benefits: Greater dexterity and visualization for the surgeon.
- Hospital stay: The robot helps avoid open surgery so patients often have same-day discharge or an overnight stay.
Open Cholecystectomy
- Traditional approach: A single, larger incision (5-7 inches) in the upper right abdomen.
- When it’s used: For severe infection, scarring from prior surgeries, or if complications arise during a laparoscopic procedure.
- Consideration: Longer hospital stay (2-5 days) and slower recovery (4-6 weeks).
Common Issues with Gallstones
Gallstones are hardened deposits of digestive fluid that form in the gallbladder. Common problems they cause include:
- Biliary Colic: Intermittent, intense pain in the upper right abdomen or center of the chest, often after eating meals.
- Acute Cholecystitis: Sudden inflammation and infection of the gallbladder, causing constant pain, fever, and nausea.
- Choledocholithiasis: Gallstones that escape the gallbladder and lodge in the common bile duct, causing jaundice (yellowing of the skin and eyes).
- Gallstone Pancreatitis: A life-threatening condition where a gallstone blocks the pancreatic duct, causing severe inflammation of the pancreas.
- Gallstone ileus: (Rare) A gallstone can travel into the intestine and cause an intestinal blockage needing emergency surgery.
Conditions When Surgery is Required
Surgery is recommended when gallstones cause symptoms or complications. You may need surgery if you experience:
- Recurrent Biliary Colic: Repeated episodes of severe pain that interfere with your quality of life.
- Acute Cholecystitis: An infected, inflamed gallbladder (often requires urgent surgery).
- Gallstone Pancreatitis: A history of pancreatitis caused by gallstones (surgery is strongly advised to prevent recurrence).
- Jaundice or Bile Duct Obstruction: Stones in the common bile duct causing liver function abnormalities.
- Large or High-Risk Polyps: Polyps larger than 1 cm that carry a risk of cancer.
- Porcelain Gallbladder: A calcified gallbladder wall associated with an increased risk of gallbladder cancer.
Asymptomatic gallstones (found incidentally on a scan) often do not require surgery unless they meet high-risk criteria.
Recovery and Post-Operative Care
In the Hospital
- Length of stay: Laparoscopic—often same-day or 1 night. Open—2-5 days.
- Pain management: Well-controlled with oral or IV medication.
- Mobility: You will be encouraged to walk within hours to prevent blood clots.
At Home (Laparoscopic Recovery Timeline)
- First 24-48 hours: Rest. Keep incisions clean and dry. Use ice packs for swelling.
- Days 3-7: Resume light activities, desk work, and driving (once off narcotics). Mild shoulder pain from gas used during surgery is normal.
- Weeks 1-2: Most patients feel back to normal. Avoid heavy lifting (>10 lbs) and strenuous exercise. Working from home or light duties are often possible.
- Weeks 2-4: Gradually return to all normal activities, including exercise.
Diet After Surgery
- Initial days: Light, low-fat foods (broth, toast, crackers, yogurt).
- First week: Gradually reintroduce normal foods. Some people find fatty or spicy foods cause temporary loose stools.
- Long-term: Most patients eat a completely normal diet with no restrictions.
Risks and Complications
Surgery is very safe, but all operations carry some risk:
- Bile Duct Injury (Rare, <0.5%): Damage to the main bile duct, a serious complication requiring specialist repair.
- Bile Leak: Bile leaking from small ducts on the liver bed, often managed with a drain or minor procedure.
- Bleeding or Infection: Uncommon, treatable with medication or drainage.
- Injury to Nearby Organs: Such as the intestine, liver, or major blood vessels (very rare).
- Post-Cholecystectomy Syndrome (5-10%): Some patients experience ongoing bloating, diarrhea, or indigestion after surgery, which usually resolves over weeks to months.
- Retained Stone: A stone left in the common bile duct, which may require a post-op ERCP procedure.
Follow-Up Care
- Incision Check: A follow-up appointment is usually scheduled after surgery to ensure proper healing and to check the microscope result (histology) of the gallbladder.
- When to Call Your Doctor: Fever, increasing pain, redness or discharge from incisions, jaundice (yellow skin), or persistent nausea/vomiting.
- Long-Term: No routine long-term follow-up is needed for uncomplicated cases. If you had gallstone pancreatitis or bile duct stones, your specialist may schedule periodic blood tests.
Gallstones in New Zealand: Statistics & Common Scenarios
NZ Statistics
- Prevalence: Approximately 10-15% of New Zealand adults have gallstones. The rate is higher among Māori and Pacific peoples.
- Surgery volume: Over 12,000 cholecystectomies are performed annually in NZ public and private hospitals.
- Gender difference: Women are 2-3 times more likely to develop gallstones than men, especially during childbearing years.
- Risk factors in NZ: High rates of obesity, type 2 diabetes, and rapid weight loss (including after bariatric surgery) contribute to gallstone formation.
Common Conditions Seen in NZ Patients
- Acute cholecystitis: Frequently seen in emergency departments, especially in patients with known gallstones.
- Gallstone pancreatitis: A leading cause of acute pancreatitis admissions in NZ hospitals.
- Recurrent biliary colic: The most common reason for elective gallbladder removal.
- Choledocholithiasis: Often requiring pre-operative ERCP (endoscopic stone removal) before surgery.
Our Procedure at the Clinic
First Consultation
- Comprehensive assessment: Review your symptoms, medical history, and any previous imaging (ultrasound, CT scan).
- Physical examination: Palpation of the abdomen to identify tenderness or a palpable gallbladder.
- Diagnostic imaging: If not already done, an abdominal ultrasound will be arranged to confirm gallstones and assess gallbladder wall thickness.
- Treatment plan discussion: We will explain the recommended surgical approach (laparoscopic, robotic, or open) based on your specific condition. Over 99% of cholecystectomies done by Dr Srinivasa are either done laparoscopically or robotically.
- Informed consent: We will thoroughly discuss the risks, benefits, and alternatives, including non-surgical options.
- Booking: Surgery will be scheduled at a convenient time and hospital. Most patients are able to have surgery within the month or sooner if required.
Surgery
- Arrival: Arrive at the hospital 1-2 hours before your scheduled time.
- Anesthesia: You will be placed under general anaesthesia (completely asleep).
- Procedure time: Laparoscopic cholecystectomy typically takes 60 minutes.
- Intraoperative cholangiography: X-ray dye is injected to map the bile ducts and ensure no stones are in the common bile duct. Dr Srinivasa does this routinely as an additional safety check.
- Recovery room: You will wake up in the post-anaesthesia care unit, where nurses will monitor your vitals.
Recovery & Post-Operative Care
- Immediately after: You will be offered pain relief, fluids, and anti-nausea medication as needed.
- Going home: Most laparoscopic patients go home within 4-6 hours of surgery (same-day discharge). Open surgery patients stay 2-5 days.
- At home care package: You will receive written instructions, a prescription for pain medication, and a 24-hour contact number.
- Return to normal activities: Most patients return to desk work within 3-7 days and resume all activities by 2-4 weeks.
Follow-Up
- Post-op appointment: Scheduled for 2-3 weeks after surgery at our clinic.
- What we check: Incision healing, pain resolution, and any digestive symptoms.
- Pathology results: If your gallbladder was sent for analysis, we will review the results with you.
Frequently Asked Questions (FAQs) About Gallbladder Surgery
Can I live a normal life without a gallbladder?
Yes, absolutely. Your liver still produces bile, which now drips continuously into your intestine. Most people have no long-term digestive issues and eat a completely normal diet.
How long does the surgery take?
A laparoscopic cholecystectomy typically takes about 60 mins from start to finish.
Will I have bad scars?
No. With laparoscopic surgery, you will have 3-4 small scars (about 1 cm each) that fade significantly over time. Open surgery leaves a larger scar but is rarely needed.
Is the surgery painful?
You will be under general anaesthesia and feel nothing during the surgery. Afterward, you may have some discomfort (soreness at incision sites, mild shoulder pain from gas), but this is well-controlled with medication and improves quickly. Most patients say that the pain from gallstones is significantly worse!
How soon can I drive?
You can typically drive again within 3-5 days, once you are no longer taking narcotic pain medication and can comfortably slam on the brakes without hesitation.
Can gallstones come back after surgery?
No. Since the gallbladder is removed, stones cannot form inside it. However, stones can rarely form in the bile ducts themselves later in life. This is uncommon in the New Zealand population but is seen in some Asian patients due to other problems (primary stone formation, liver fluke infection).
Why would a laparoscopic surgery be converted to open?
Conversion is not a complication; it’s a sign of a safe surgeon. It may be done to avoid injury to the bile duct or blood vessels if there is severe inflammation or unusual anatomy.
How do I know if I need my gallbladder out?
The most common signs are repeated attacks of sharp pain in your upper right abdomen (often after fatty meals). An ultrasound is the first test to confirm gallstones.
What is post-cholecystectomy syndrome?
A term for persistent bloating, diarrhea, or indigestion after surgery. It affects about 5-10% of patients and usually resolves within weeks to months. It is rarely severe.
Is the surgery covered by insurance in NZ?
Yes. Medically necessary gallbladder surgery is covered by public health system (Te Whatu Ora) for eligible patients, though there may be a waiting list. Private health insurance also covers the procedure, often with shorter wait times. Dr Srinivasa is an affiliated provider with most major insurers and thus has standing pre-approval when surgery is deemed necessary.
