Cholecystectomy (Gallbladder Removal) — How It Works, Benefits & Recovery — Procedure Guide, Recovery & Risks | MyMedicPlus

Cholecystectomy is the surgical removal of the gallbladder — the small pear-shaped organ beneath the right lobe of the liver that stores and concentrates bile produced by the liver. It is the definitive and most effective treatment for symptomatic gallstone disease, acute and chronic cholecystitis (gallbladder inflammation), and biliary dyskinesia (poor gallbladder emptying). Laparoscopic cholecystectomy (keyhole surgery) is the gold standard approach, performed through 3–4 small (5–12 mm) abdominal incisions, and accounts for over 90% of cholecystectomies worldwide. The procedure was first performed laparoscopically in 1987 and rapidly replaced open surgery due to superior recovery profile, reduced wound complication rates, and equivalent safety. Open cholecystectomy through a right subcostal (Kocher) incision is reserved for patients with previous right upper abdominal surgery, obesity preventing adequate laparoscopic access, or conversion from laparoscopy due to bleeding or unclear anatomy. Approximately 750,000 cholecystectomies are performed annually in the United States and over 60,000 in the United Kingdom, making it one of the most commonly performed general surgical procedures globally. Laparoscopic cholecystectomy is the most common elective abdominal operation in the world, with over 700,000 performed annually in the United States and approximately 70,000 each year in England.

Cholecystectomy is recommended for symptomatic gallstone disease and its complications. Primary indications include: biliary colic — recurrent right upper quadrant or epigastric pain typically 15 minutes to 6 hours after fatty meals, caused by stones transiently obstructing the cystic duct; acute cholecystitis — inflammation of the gallbladder from cystic duct obstruction (fever, right upper quadrant tenderness, elevated inflammatory markers), treated with early laparoscopic cholecystectomy within 72 hours of admission; gallstone pancreatitis — cholecystectomy should be performed during the index admission for mild pancreatitis or within 2 weeks of recovery, as delaying carries a 30–50% risk of recurrent pancreatitis within 6 weeks; common bile duct stones (choledocholithiasis) — treated endoscopically (ERCP) followed by cholecystectomy; gallbladder polyps greater than 10 mm in diameter (malignancy risk); and biliary dyskinesia with gallbladder ejection fraction less than 35% on HIDA scan. Asymptomatic gallstones in otherwise healthy patients are not routinely treated surgically, as the annual risk of developing symptoms is only 1–2% per year. The exception is gallstones in patients undergoing bariatric surgery where concurrent cholecystectomy is sometimes performed.

Laparoscopic cholecystectomy is performed under general anaesthesia. A Veress needle or Hasson technique introduces the first trocar at the umbilicus. CO2 pneumoperitoneum is established at 12–15 mmHg. A 10 mm camera port is placed at the umbilicus, and 2–3 additional working ports (5–12 mm) are placed in the right upper abdomen and epigastrium under direct vision. The patient is placed in reverse Trendelenburg (head-up) position with left lateral tilt to allow gravity to move the bowel away from the operating field. The hepatoduodenal ligament is dissected and the critical view of safety (CVS) is established — a standardised step requiring full exposure of the cystic duct and cystic artery origin at the gallbladder before any structure is divided. This CVS technique is the most important safeguard against bile duct injury. Once CVS is achieved, the cystic duct and cystic artery are double-clipped and divided. The gallbladder is dissected from the liver bed with electrocautery and retrieved in an extraction bag through the umbilical port. An intraoperative cholangiogram through the cystic duct may be performed if bile duct stones are suspected. Haemostasis at the liver bed is secured, ports removed, port sites closed. Total operative time: 30–90 minutes. Total operative time for elective laparoscopic cholecystectomy is typically 45–75 minutes.

Laparoscopic cholecystectomy resolves biliary colic and prevents recurrent gallstone-related complications in over 95% of patients. Postoperative mortality for elective laparoscopic cholecystectomy is less than 0.1% — among the lowest of any abdominal surgical procedure. Major morbidity (bile duct injury, significant bleeding) occurs in 1–2% of cases. Compared to open cholecystectomy, laparoscopic surgery offers: same-day or next-day discharge (versus 3–5 day hospital stay); return to driving within 1–2 weeks (versus 6 weeks); return to full activity within 2 weeks (versus 4–6 weeks); significantly lower wound infection rates; and substantially less postoperative pain requiring opioid analgesia. The gallbladder is not an essential organ for normal digestion — the liver continues to produce bile which drains continuously into the duodenum without the gallbladder reservoir. The majority of patients can eat a normal diet without restriction within 2–4 weeks of surgery. Post-cholecystectomy syndrome (persistent or new upper abdominal symptoms after surgery) affects 5–10% of patients and is usually caused by unrecognised common bile duct stones, sphincter of Oddi dysfunction, or pre-existing functional gastrointestinal disorders.

Bile duct injury is the most serious complication of cholecystectomy, occurring in 0.1–0.5% of laparoscopic cases (higher than the 0.05–0.2% rate for open surgery, reflecting the learning curve of the laparoscopic era now largely overcome). Major bile duct injuries require biliary reconstruction (hepaticojejunostomy) and specialist hepatobiliary surgical expertise. Bile leak from a clip slipping off the cystic duct stump or an accessory bile duct in the liver bed occurs in 0.5–1% and is usually managed endoscopically (ERCP, stent). Wound infection at port sites occurs in 1–2%. Conversion from laparoscopic to open surgery is required in approximately 5% of cases due to dense adhesions from prior surgery, uncontrolled bleeding, or inability to establish CVS safely. Retained common bile duct stones may be identified post-operatively by abnormal liver function tests or biliary symptoms and are treated by ERCP. Port-site hernia (Richter-type) occurs in less than 1% at 12 mm umbilical port sites and is reduced by fascial closure. Shoulder-tip pain from diaphragmatic irritation by residual CO2 resolves spontaneously within 24 hours.

Most patients undergoing elective laparoscopic cholecystectomy are discharged the same day or after one overnight stay, once pain is controlled on oral analgesics and oral diet is tolerated. Shoulder-tip pain from residual CO2 gas is common for 12–24 hours and resolves spontaneously. Diet can be advanced from clear fluids to normal food on the evening of surgery — no special dietary restrictions are required long-term, though a lower-fat diet in the first 2–4 weeks reduces the frequency of loose stools while intestinal adaptation occurs. Paracetamol and ibuprofen are typically sufficient for pain management. Driving resumes when comfortable (usually 5–7 days, or after stopping opioids). Light desk work may resume after 5–7 days; physically demanding work after 2–4 weeks. The umbilical port-site is the most painful post-operative incision site due to fascial closure. Showering is permitted after 48 hours; bathing and swimming should wait until wounds are fully healed (10–14 days). Patients should contact their surgeon or emergency department if they develop fever, worsening abdominal pain, or jaundice (yellow skin or eyes) within the first 2 weeks after surgery, as these may indicate a bile leak or missed common bile duct stone.
