Gallbladder removal surgery, known medically as cholecystectomy, is the surgical removal of the pear-shaped organ that sits beneath the liver and stores bile. It is among the most frequently performed procedures in general surgery worldwide, most often carried out because of painful attacks caused by gallstones, cholecystitis, or other conditions that threaten the bile ducts. Since laparoscopic (keyhole) techniques became the standard of care, hospital stays have become shorter and patients typically return to daily life considerably faster. This page brings together the clinically relevant aspects of gallbladder surgery — from how the decision for surgery is made through to postoperative follow-up — from the perspective of the General Surgery department at Koru Hospital in Ankara, with international patients in mind.
What Is Gallbladder Surgery and When Is It Considered?
Cholecystectomy is defined as the surgical removal of the small sac-like organ located under the right lobe of the liver, whose role is to store bile and release it into the duodenum during meals. The operation may be performed either electively or as an emergency. In everyday clinical practice, the most common indication is symptomatic cholelithiasis — gallstone disease that produces complaints. Other principal reasons for recommending the operation include acute cholecystitis, chronic cholecystitis, biliary pancreatitis, cholecystoduodenal fistula, porcelain gallbladder, gallbladder polyps larger than ten millimetres, and suspicion of gallbladder cancer. In selected patients who also have stones in the common bile duct, the duct may first be cleared by ERCP before or during the operation, after which the gallbladder itself is removed.
The technical foundation of the procedure is the safe exposure of the anatomical area known as Calot's triangle, formed by the cystic duct, the cystic artery and the common hepatic duct. Modern surgical practice emphasises the concept of the Critical View of Safety: no structure is divided until the cystic duct and cystic artery have been clearly identified. This principle markedly reduces the risk of bile duct injury and helps prevent serious postoperative problems such as cholangitis, bile leakage and duct strictures. Where the surgeon considers it necessary, intraoperative cholangiography can be performed to confirm the integrity of the main bile duct and to check radiologically for any remaining stones.
Beyond its medical definition, gallstone disease has a direct impact on quality of life. Recurrent attacks of biliary colic, pain in the right upper abdomen radiating towards the shoulder blade, intolerance of fatty foods, nausea and vomiting can significantly restrict work and social activities. In the diagnostic work-up, abdominal ultrasound is regarded as the reference examination; magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasound and computed tomography are used where needed. The decision for surgery is shaped through a multidisciplinary assessment that weighs the severity of symptoms, the risk of complications, and the patient's age and coexisting conditions. In people who carry gallstones without symptoms, the indication for surgery is applied narrowly; priority is given to patients with diabetes, immunosuppression, stones larger than three centimetres, porcelain gallbladder, disease of the common bile duct, or features raising concern for gallbladder cancer. In patients scheduled for bariatric (weight-loss) surgery, prophylactic cholecystectomy may be considered under specific circumstances, because rapid weight loss increases the likelihood of new gallstone formation.
Which Techniques Are Used? Laparoscopic and Open Approaches
The laparoscopic, or "keyhole", approach is currently the accepted standard for cholecystectomy. Through four small ports placed in the abdominal wall, the abdominal cavity is expanded with carbon dioxide gas, and the operation is completed using a high-resolution camera and fine instruments. Ports of 5 to 10 millimetres are usually positioned around the navel, below the breastbone and in the right upper abdomen. Alongside the classic four-port technique, single-incision laparoscopic surgery (SILS) and robotic cholecystectomy may be options in carefully selected cases. Robotic systems can offer additional manoeuvrability, particularly in patients with obesity, complex anatomy, or when reconstructive work on the bile ducts is required.
Open cholecystectomy — reaching the gallbladder directly through a right subcostal (Kocher) incision — is used far less often today but remains valid in specific situations. Indications for an open approach include generalised peritonitis, dense adhesions, bleeding that cannot be controlled laparoscopically, suspected bile duct injury, Mirizzi syndrome, suspicion of gallbladder cancer, and serious heart or lung conditions that make the patient unable to tolerate the gas insufflation required for laparoscopy. In a proportion of operations that begin laparoscopically, the surgeon may convert to open surgery because Calot's triangle cannot be exposed safely, because of significant bleeding, or because of unexpected anatomical variations. This conversion rate is reported in surgical series at around two to five per cent.
The choice of technique is not simply a matter of surgeon preference: it depends on the patient's clinical condition, any previous abdominal operations, the degree of inflammation in the gallbladder, whether common bile duct disease is present, and the experience of the surgical team. Subtotal cholecystectomy — removing most of the gallbladder while leaving the infundibulum in place — is an established bail-out option when severe scarring in Calot's triangle makes safe dissection impossible. All of these technical options are individualised by interpreting preoperative imaging together with the findings at operation, with the aim of keeping the risk of complications as low as reasonably possible. In experienced centres, intraoperative fluorescence cholangiography using indocyanine green dye allows the bile ducts to be visualised in real time and is a useful adjunct for recognising anatomical variations early. Where a patient also needs another procedure — such as umbilical or inguinal hernia repair, bariatric surgery or another upper abdominal operation — cholecystectomy can often be combined in the same session, shortening the overall recovery period.
How Long Does the Operation Take?
Operating time varies with the technique used, the degree of inflammation, the patient's anatomy and any accompanying conditions. An uncomplicated elective laparoscopic cholecystectomy is typically completed within forty-five to ninety minutes. Roughly fifteen minutes of this is taken up by preparation — positioning the patient, induction of anaesthesia, skin preparation and draping. The surgical stages themselves — dissection, clipping of the cystic duct and cystic artery, and separating the gallbladder from its bed on the liver — usually take between half an hour and one hour. Open cholecystectomy generally takes sixty to one hundred and twenty minutes, partly because closing the abdominal wall adds to the overall time.
When the operation is performed for acute cholecystitis, oedema, adhesions and inflammatory thickening can prolong the dissection considerably. Tissues become more fragile once more than seventy-two hours have passed since the onset of symptoms, which lengthens the operation and increases the likelihood of conversion to open surgery. For this reason, early laparoscopic cholecystectomy is favoured in acute cholecystitis: when the patient is stable, surgery is ideally planned within the first seventy-two hours. If stones are present in the common bile duct, intraoperative cholangiography or laparoscopic exploration of the duct adds a further thirty to sixty minutes.
Body mass index and previous abdominal surgery are additional factors that influence operating time. In patients with obesity, a restricted view inside the abdomen, fatty tissue planes and more difficult port placement can extend the procedure, while adhesions from earlier upper abdominal operations require extra time to release. In young patients with uncomplicated disease treated electively in experienced centres, the operation may take as little as thirty-five to forty minutes. Duration on its own, however, is not treated as a measure of quality: achieving a safe view, handling tissues carefully and avoiding complications remain the overriding priorities.
What Does Recovery Look Like After Gallbladder Surgery?
For the majority of patients, recovery after laparoscopic cholecystectomy is quick and comfortable. After one to two hours of observation in the recovery room, patients are transferred to the ward and can usually begin drinking clear fluids on the evening of the operation. A hospital stay of one to two days is typical; in selected patients managed under Enhanced Recovery After Surgery (ERAS) protocols, same-day discharge may be possible. After open cholecystectomy, the hospital stay tends to be longer — around three to five days — because the abdominal incision heals more slowly.
The most common complaints in the early postoperative period are mild pain at the port sites, abdominal bloating, and shoulder pain caused by carbon dioxide gas irritating the diaphragm. The shoulder pain usually settles by itself within twenty-four to forty-eight hours. Pain is generally well controlled with paracetamol and non-steroidal anti-inflammatory medication. Patients are helped out of bed within a few hours of surgery; early mobilisation reduces the risk of deep vein thrombosis and lung complications. Fine absorbable sutures or skin adhesive at the port sites keep dressing requirements to a minimum, and most patients can shower about two days after the operation.
Patients with desk-based jobs can usually return to work one to two weeks after laparoscopic surgery, while those in physically demanding occupations are advised to rest for four to six weeks. Heavy lifting, exercises that strain the abdominal muscles, and swimming are postponed for the first four to six weeks, whereas walking, light household activity and climbing stairs are encouraged early on. A follow-up visit is planned ten to fifteen days after surgery to review the pathology report, check the wounds and arrange further imaging if needed. Rarely, late problems such as a hernia at the umbilical port site, port-site infection or persistent right upper abdominal pain can occur; recognised early, these can usually be managed effectively. Patients are advised to contact the surgical team without delay if they develop fever, jaundice, widespread abdominal tenderness, persistent nausea and vomiting, ongoing distension, or bile-stained discharge from the port sites. At early and later follow-up visits, eating habits, weight change, bowel pattern and possible symptoms of post-cholecystectomy syndrome are reviewed, and additional imaging, laboratory tests or endoscopic assessment are arranged when required.
Which Tests and Preparations Come Before the Operation?
Preoperative assessment is a decisive step for the safety and success of the operation. It begins with a detailed history covering the course of the gallstone disease, pain attacks, episodes of jaundice, previous pancreatitis, itching, dark urine and pale stools. Coexisting conditions such as diabetes, high blood pressure, coronary artery disease, chronic obstructive pulmonary disease, thyroid disorders and bleeding tendencies are recorded carefully. Current medication is reviewed with particular attention to anticoagulants and antiplatelet drugs; where necessary, some of these are paused before surgery or replaced temporarily with bridging therapy.
Standard laboratory tests include a full blood count, liver and kidney function tests, blood glucose, coagulation parameters, blood group typing and serological screening. Raised liver enzymes, elevated bilirubin or a high alkaline phosphatase raise the possibility of common bile duct disease, in which case MRCP is used to evaluate the bile ducts. Abdominal ultrasound is performed routinely to assess the thickness of the gallbladder wall, the number and size of stones, the diameter of the common bile duct and the liver tissue itself. In patients over forty and in those with heart or lung disease, a chest X-ray, an electrocardiogram and a cardiology consultation are arranged.
The anaesthesia consultation is a core component of preparation. Airway assessment, ASA risk classification, the degree of control of coexisting illnesses and, where indicated, pulmonary function tests are reviewed at this stage. Solid food is stopped six to eight hours before surgery and clear fluids two hours before. Where the planned port sites are densely covered with hair, the skin is clipped and then prepared with antiseptic solution. A single dose of prophylactic antibiotics is usually given thirty to sixty minutes before the operation, and mechanical — and where appropriate pharmacological — measures are taken to prevent venous thromboembolism. Patients who smoke are advised to stop, ideally at least two to four weeks beforehand. Optimising blood sugar in diabetic patients, stabilising blood pressure in hypertensive patients and correcting anaemia are further important elements of preparation.
How Should You Eat After the Gallbladder Has Been Removed?
Once the gallbladder has been removed, bile produced by the liver flows continuously into the duodenum instead of being stored and released with meals. Although this physiological change causes no significant long-term problems in most patients, a gradual adjustment of eating habits is recommended in the early weeks. On the first day after surgery, patients start with clear fluids, warm soups and plain stewed fruit; from the second day onwards, soft, low-fat foods are introduced. Boiled vegetables, plain rice, low-fat white cheese, oatmeal, grilled chicken and steamed fish are usually well tolerated during this period.
A low-fat eating plan is advised for the first week: fried foods, mayonnaise-based sauces, creamy desserts, fatty red meat, butter, clotted cream and fast food are best avoided. Caffeine, heavily spiced dishes, carbonated drinks and foods with a high carbohydrate load are also kept limited. Eating small portions five to six times a day supports digestive comfort and allows bile to reach the intestine in smaller, better tolerated amounts. Drinking around two to two and a half litres of fluid daily helps to prevent constipation and digestive complaints.
Most patients can return step by step to a normal diet from about the third or fourth week. At that point, healthy fat sources such as olive oil, walnuts, hazelnuts, avocado and fish can be reintroduced in moderate portions. A small proportion of patients experience what is known as post-cholecystectomy diarrhoea; this usually settles within a few months. High-fibre foods, whole grains, oats and soluble fibre supplements can help reduce this complaint. If persistent digestive problems, weight loss, chronic diarrhoea or jaundice develop, further investigation is arranged, and possibilities such as a bile duct stricture, a retained stone or a functional bowel disorder are considered. For the long term, regular physical activity, maintaining a weight close to the ideal range, limiting red meat and eating fish two to three times a week are general recommendations. For patients with high cholesterol, an individualised nutrition plan drawn up with a dietitian can support both digestive comfort and cardiovascular risk management.
What Are the Possible Risks and Complications?
In experienced hands cholecystectomy is considered a safe procedure, yet like any operation it carries a defined risk profile. General surgical risks include reactions to anaesthesia, bleeding, infection, deep vein thrombosis and pulmonary embolism. The temporary cardiopulmonary changes caused by carbon dioxide insufflation are monitored with particular care in patients with existing heart or lung disease. Injury to the bowel, bladder or major blood vessels during port placement is rare but serious. With the open technique, wound infection, incisional hernia and respiratory complications are the corresponding concerns.
The most important complication specific to cholecystectomy is bile duct injury. Injury to the common hepatic duct or the common bile duct is reported in roughly three to five per thousand operations; early recognition and management in an experienced hepatobiliary centre are essential, and prompt, appropriate reconstruction is decisive for the long-term outcome. Another notable complication is bile leakage from the cystic duct stump or from small bile channels, seen in about one to two per cent of cases; it is usually managed effectively with endoscopic stent placement or percutaneous drainage. Stones overlooked in the common bile duct during surgery — retained stones — are cleared by ERCP.
Bleeding, which may arise from the liver bed or the cystic artery, is reported in around one per cent of cases. A hernia can develop later at the umbilical port site, with a higher risk in patients with obesity. Less commonly, wound infection, intra-abdominal abscess or persistent right upper abdominal complaints known as post-cholecystectomy syndrome can occur. Post-cholecystectomy syndrome may have several underlying causes — sphincter of Oddi dysfunction, a retained stone, a bile duct stricture or functional dyspepsia — and differentiating between them requires imaging and endoscopic evaluation. The conversion rate from laparoscopic to open surgery is between two and five per cent; converting is regarded not as a failure but as a decision that puts safety first. The key elements of risk reduction are an experienced surgical team, appropriate patient selection, achieving the Critical View of Safety in Calot's triangle, and a low threshold for intraoperative cholangiography when doubt arises.
Which Type of Anaesthesia Is Used?
General anaesthesia is the standard for cholecystectomy. In both the laparoscopic and the open technique the patient is fully asleep, and breathing is controlled through an endotracheal tube. In laparoscopic surgery, the carbon dioxide used to inflate the abdomen pushes the diaphragm upwards and alters respiratory mechanics, which is why controlled mechanical ventilation is required. Anaesthesia is usually induced with propofol, short-acting opioids and non-depolarising muscle relaxants, and maintained with inhalational agents or total intravenous anaesthesia. In elective cases, the duration of anaesthesia parallels the operation and averages one to two hours.
The pre-anaesthetic assessment examines the airway in detail — Mallampati score, neck mobility and mouth opening — and reviews cardiovascular and pulmonary disease, any history of sleep apnoea, gastro-oesophageal reflux and previous experiences with anaesthesia. The ASA physical status classification guides this evaluation; for higher-risk patients, additional monitoring and a planned stay in intensive care after surgery are organised in advance. Standard intraoperative monitoring includes ECG, non-invasive blood pressure, pulse oximetry, capnography and body temperature; invasive arterial pressure monitoring and central venous access are added where clinically indicated.
Postoperative pain relief follows the principle of multimodal analgesia: paracetamol and non-steroidal anti-inflammatory drugs are combined, with short courses of mild opioids where needed. Local anaesthetic infiltration of the port sites, transversus abdominis plane (TAP) blocks and wound infiltration contribute to early pain control. Anti-nausea medication is given during induction and in the postoperative period to prevent nausea and vomiting. In selected patients with serious cardiopulmonary risk, open surgery under high thoracic epidural anaesthesia may be considered, although the standard approach in current practice remains laparoscopic surgery under general anaesthesia. At Koru Hospital, the General Surgery team works in close coordination with the anaesthesiology and intensive care units, and the anaesthetic and surgical plan is tailored to each patient individually.
