Gallbladder removal, called cholecystectomy, is the most common abdominal surgery in the United States, with over 750,000 performed each year. The vast majority are done laparoscopically, through four small incisions, and most people go home the same day. Here’s what actually happens before, during, and after the procedure.
How Laparoscopic Surgery Works
The surgeon makes four small cuts in your abdomen, each roughly 5 to 12 millimeters wide. The first goes near your belly button, where the surgeon places a camera port. Three more go under your right ribcage and near the center of your upper abdomen. Carbon dioxide gas is pumped into your abdominal cavity to inflate it, giving the surgeon room to see and work. A tiny camera feeds a live image to a monitor, and the surgeon operates by watching that screen while using long, thin instruments inserted through the other ports.
The surgical goal is straightforward: disconnect the gallbladder from the bile duct system and its blood supply, then pull it out through one of the small incisions. The surgeon first identifies the cystic duct (the tube connecting the gallbladder to the main bile duct) and the cystic artery that feeds it blood. Both are clipped with small metal or plastic clips and then cut. The gallbladder is then peeled away from the underside of the liver where it sits and removed through the belly button incision, often inside a small plastic bag.
For patients who are obese, the port locations shift slightly because the belly button sits lower relative to the liver. If you’ve had previous abdominal surgery near the belly button, the surgeon may use an alternative entry point to avoid scar tissue.
When Open Surgery Is Needed
Sometimes the surgeon needs to make a single larger incision, about 15 centimeters long, under the right ribcage instead of using small ports. This open approach is planned from the start when there’s suspected gallbladder cancer, severe liver disease with bleeding risks, or portal hypertension (high pressure in the liver’s blood vessels that can cause dangerous bleeding during port placement). Pregnant patients in their third trimester may also need open surgery because the enlarged uterus makes laparoscopic port placement difficult.
Other times, the switch happens mid-operation. A surgeon may begin laparoscopically and convert to open surgery if there’s unexpected bleeding or if inflammation has distorted the anatomy so badly that the structures can’t be safely identified through the camera. This isn’t a complication or a failure. It’s a safety decision, and it happens in a small percentage of cases.
How Surgeons Protect the Bile Ducts
The biggest risk during gallbladder removal is accidentally injuring the common bile duct, the main tube that carries bile from the liver to the small intestine. Bile duct injuries occur in roughly 0.3% to 0.5% of laparoscopic cases, compared to 0.1% to 0.25% in open surgery. The slightly higher rate with laparoscopic surgery comes from the limited field of view and the difficulty of distinguishing inflamed tissue through a camera.
To reduce this risk, some surgeons use a technique called intraoperative cholangiography. While you’re under anesthesia, a thin tube is threaded into the cystic duct and contrast dye is injected. X-ray images then show the dye flowing through the bile duct system in real time, giving the surgeon a map of the anatomy before making critical cuts. This helps confirm that the right structures are being clipped and can also reveal gallstones that may have migrated into the bile duct.
What About Robotic Surgery?
Some hospitals offer robotic-assisted gallbladder removal, where the surgeon sits at a console and controls robotic arms that hold the instruments. The setup provides a 3D view and greater range of motion at the instrument tips. However, a large study of over 737,000 Medicare patients found that bile duct injuries were significantly higher with robotic procedures compared to standard laparoscopic surgery, and reoperations were more common. Complication and readmission rates were otherwise similar between the two approaches. The robotic option doesn’t appear to offer a recovery advantage for this particular operation.
Recovery After Laparoscopic Surgery
Most people leave the hospital the same day or the next morning. Soreness around the incision sites and some shoulder pain from the residual gas in your abdomen are normal for the first few days. The shoulder discomfort happens because carbon dioxide can irritate the diaphragm, and the brain interprets that as pain in the shoulder area. It passes on its own.
Most people return to desk work within one to two weeks. If your job involves heavy lifting or physical labor, you’ll likely need to modify your activity for longer. Recovery from open surgery takes more time, typically four to six weeks, because of the larger incision and the muscle tissue that needs to heal.
Eating After Surgery
Without a gallbladder, your liver still produces bile, but instead of being stored and released in a concentrated burst when you eat fat, it now drips steadily into the small intestine. This means your body can still digest fat, just less efficiently in large amounts at first.
For at least the first week, stick to low-fat foods (3 grams of fat or less per serving). Avoid fried foods, greasy meals, and heavy sauces. Eating smaller, more frequent meals helps because smaller portions mix better with the steady trickle of bile your body now provides. Lean protein like chicken, fish, or fat-free dairy paired with vegetables, fruits, and whole grains is a good baseline.
Gradually increase fiber with foods like oats and barley to help regulate bowel movements, but add it slowly over several weeks to avoid gas and cramping. Caffeine, dairy, and very sweet foods can worsen diarrhea in the early weeks, so ease back into those. Most people return to a normal diet within a month or two.
Long-Term Digestive Changes
About 10% to 15% of patients develop ongoing symptoms after gallbladder removal, sometimes called postcholecystectomy syndrome. The two main patterns involve opposite ends of the digestive tract. The constant flow of bile into the upper gut can contribute to stomach irritation or acid reflux. In the lower gut, bile reaching the colon can cause loose stools, diarrhea, and crampy lower abdominal pain.
The likelihood varies by age and sex. Women experience these symptoms at roughly twice the rate of men (28% versus 15% in one analysis). Symptoms are most common in people between their 20s and 50s and less common at the extremes of age. The good news: when researchers followed up with patients long-term, about 65% reported no symptoms at all, 28% had mild symptoms, and only about 2% described their symptoms as severe. For many people who had gallbladder symptoms before surgery, life after removal is a clear improvement. One study found 62% of patients felt significantly better than before their operation.
