Understanding Biliary Tract Operations

Biliary tract operations are surgical procedures that address problems affecting the bile ducts, gallbladder, and liver—organs essential for digestion. These surgeries help restore normal function when conditions like gallstones, blockages, or tumors disrupt the flow of bile.

What are Biliary Tract Operations?

Biliary tract operations refer to a range of surgical procedures designed to treat diseases and conditions affecting the biliary system, which includes the bile ducts, gallbladder, and liver^[1]. The biliary system plays a crucial role in digestion, particularly in the breakdown and absorption of fats. The liver produces a fluid called bile and stores it in the gallbladder. The gallbladder releases bile into the small intestine to help digest your food^[3].

When conditions such as gallstones, bile duct obstructions, or tumors arise, surgery becomes a necessary intervention to restore normal bodily function^[1]. These procedures can involve various techniques, including laparoscopic and open surgery, depending on the complexity of the condition.

Common Conditions Requiring Surgery

There are several common conditions that often lead to biliary tract surgery. One of the most prevalent is gallstones, which can form in the gallbladder and cause intense pain or blockages in the bile ducts^[1]. For patients experiencing frequent gallbladder attacks or serious complications, cholecystectomy (gallbladder removal) becomes a common recommendation. This straightforward procedure can significantly improve quality of life by alleviating pain and preventing further complications.

Common bile duct stones are gallstones that move out of your gallbladder and get stuck in your common bile duct, which is a tube that connects your gallbladder and liver to your intestines^[4]. If bile ducts become blocked, bile cannot get to the small intestine, and this may lead to inflammation or infection of the entire biliary system, known as cholangitis^[3].

Another condition that might necessitate surgery is cholangitis, which is an infection of the bile duct that can present life-threatening symptoms if not treated promptly^[1]. Patients with this condition might experience jaundice (yellowing of your skin and whites of your eyes), fever, and abdominal pain. Surgical intervention aims to clear the obstruction causing the infection.

Biliary tract surgery can also address tumors located in the bile ducts or gallbladder. These tumors, whether benign or malignant, may require imaging tests for diagnosis and possibly surgical resection to remove cancerous cells^[1]. Surgery aims to remove the cancer and some healthy tissue around it, giving the best chance of a cure^[7].

Types of Biliary Tract Surgeries

Biliary tract surgeries primarily fall into two broad categories: laparoscopic and open surgeries. Laparoscopic surgery, also known as minimally invasive surgery, involves small incisions and the use of a camera to guide the surgeon^[1]. This technique not only results in reduced pain and scarring but also promotes quicker recovery times. Patients typically go home the same day or the next day after surgery, which is a huge advantage of this approach.

During laparoscopic gallbladder surgery, the surgeon makes several small cuts (incisions) in your abdomen. They insert a thin tube with a light (laparoscope) and inflate your belly with gas. The surgeon uses the laparoscope’s built-in camera to see your gallbladder^[8]. A laparoscopic cholecystectomy normally takes about 60 to 90 minutes^[8].

On the other hand, open surgery may be necessary for complex cases that involve extensive manipulation or in patients with significant prior complications^[1]. This type of surgery requires a larger incision and allows full access to the surgical field, which can be critical in certain scenarios. An open cholecystectomy takes about one to two hours^[8].

Biliary interventions are minimally invasive procedures that treat bile ducts that are blocked, narrowed, or injured and gallbladders that are inflamed or infected^[3]. These include procedures such as percutaneous transhepatic biliary drainage (PTBD), where a catheter is inserted into blocked ducts in the liver so bile can drain out of the body, and percutaneous cholecystostomy, where a thin plastic tube is placed through the skin into an infected gallbladder to let fluids drain and reduce swelling^[3].

Preparing for Surgery

Preparation for biliary tract surgery is essential to ensure a smooth surgical experience. To get you ready for surgery, your care team will run lab tests to make sure you’re healthy enough for the procedure. They will explain the surgery and get your consent. You will be asked to avoid eating, smoking and certain medications beforehand to help prevent complications^[8].

If you smoke, stopping smoking now may reduce your risk of developing complications and will improve your long-term health. Try to maintain a healthy weight, as you have a higher risk of developing complications if you are overweight. Regular exercise should help to prepare you for the operation, help you to recover and improve your long-term health^[4].

Your surgeon will first need to find out where the stones are in your common bile duct, if applicable. They may prescribe an antibiotic and tell you not to eat or drink for several hours before your procedure. They may also tell you to stop taking aspirin or blood thinners^[3].

What Happens During Surgery

The operation is performed under a general anaesthetic and usually takes 1 to 2 hours^[4]. When it’s time, you’ll get an IV for fluids and medicine. You’ll go under general anesthesia. A breathing tube will help keep your airway open during surgery^[8].

During laparoscopic surgery, your surgeon will make a small incision near your belly button and two to three more in your upper right abdomen. They will inflate your abdomen with gas to create space, insert a laparoscope (camera) to view the area on a monitor, and use thin tools to remove your gallbladder. They will then release the gas and close the incisions with stitches^[8].

If your surgeon finds any gallstones in the duct, they will try to remove them through the cystic duct or the common bile duct. Various techniques can be used, including a wire basket or a tube with an inflatable balloon at the end (balloon catheter)^[4].

The type of surgery you have depends on where the bile duct cancer is, if cancer removal is needed. During the operation, your surgeon removes the cancer and a border of tissue around it. This is called the margin^[7].

Recovery After Surgery

Your recovery after surgery will depend on what operation you have had. It also depends on your general health^[20]. Having bile duct cancer removed is major surgery. Many hospitals follow an Enhanced Recovery Programme (ERP), which encourages people to move around soon after their operation. They may also start eating and drinking not long after surgery. This helps them recover quicker and have less complications^[20].

When you wake up after your operation, you will have several tubes in you. You might have drips to give you blood transfusions and fluids, wound drains to drain any blood, bile or fluid from around the operation site, a tube down your nose into your stomach (nasogastric tube) to drain bile and stop you from feeling sick, and a tube into your bladder (catheter) to measure how much urine you pass^[20].

It’s normal to have pain for the first week or so. You have painkillers to help. Tell your doctor or nurse as soon as you feel any pain. They need your help to find the right type and dose of painkiller for you^[20].

Most patients who’ve undergone a laparoscopic procedure can return home the same day as their surgery. But don’t expect to return to your normal activities right away. Give your body a day or two to rest^[21]. Because laparoscopic surgery uses smaller incisions, it usually takes about a week to heal^[1].

Dietary Changes After Gallbladder Removal

Although you can live well and healthily without your gallbladder, you may need to adjust your lifestyle during your recovery and long-term^[19]. Most people experience a temporary adjustment period in their digestive systems after gallbladder removal. For the first month or so, you might have more trouble digesting fats and heavier meals. This should gradually improve over time^[8].

One of the most effective strategies post-surgery is to avoid large, heavy meals. Your gallbladder’s job was to store bile and release it in response to fatty foods. Without it, your liver still produces bile, but it flows into your digestive system at a steady pace—regardless of what you eat^[18]. Eat 4–6 small meals throughout the day and keep portion sizes moderate.

You don’t need to eliminate all fats from your diet, but you do need to choose fats wisely^[18]. Good fats include olive oil, avocados, nuts and seeds (in small portions), and fatty fish like salmon or mackerel. Foods and drinks to avoid include high-fat items such as butter and full-fat dairy, fried foods, processed meats, processed baked goods, caffeinated drinks, coconut oil, salad dressings or sauces high in oil, foods high in sugar, and spicy foods^[19].

When you start eating and drinking again, you have sips of water before building up to other drinks then food. Once you’re able to drink without being or feeling sick your nurse takes out your drip^[20]. Pamper your stomach as well for two to three days with a diet that’s easy to digest. Start with clear liquids, broth, and gelatin, and then add solid foods gradually^[21].

Fiber is an essential part of your diet. However, too much of it too soon after gallbladder removal can cause unpleasant symptoms^[19]. Start with gentle sources such as cooked vegetables, oatmeal, brown rice, and ripe fruits like bananas and apples. Increase fiber gradually, and drink plenty of water to help your system adjust.
