Deciding on Surgery in Asymptomatic Gallstones
A 54-year-old woman is referred to the general surgical clinic after an ultrasound performed for vague upper abdominal discomfort showed multiple gallstones with a normal-calibre common bile duct and no wall thickening. She has had no episodes of colicky right upper quadrant pain, no jaundice, no fever, and no pancreatitis. Her only symptoms are intermittent bloating and dyspepsia after fatty meals. She is otherwise well, BMI 31, non-smoker, no diabetes. She has read online that leaving gallstones alone can 'cause cancer' and asks to be listed for a laparoscopic cholecystectomy. She is keen to have 'it sorted out'.
1. How would you counsel her about whether surgery is indicated?

This is asymptomatic (incidental) cholelithiasis. The bloating and fatty-food dyspepsia are non-specific and are not reliably attributable to gallstones; cholecystectomy does not reliably relieve such symptoms, and operating on them risks leaving her with persistent symptoms plus the morbidity of surgery.
The judgement is to recommend against cholecystectomy for these symptoms and explain why:
- The natural history of truly asymptomatic stones is mostly benign; most people never develop complications.
- Prophylactic cholecystectomy is not indicated for asymptomatic stones in the general population - the numbers needed to treat to prevent one complication are high, while the risks of surgery (bile duct injury, conversion, infection, anaesthetic risk) are immediate and real.
- The cancer concern should be addressed honestly: gallbladder cancer is rare, and prophylactic surgery for asymptomatic stones is not justified on that basis. (Exceptions where prophylactic surgery is considered include certain high-risk groups - e.g. calcified/porcelain gallbladder, very large stones, some haemolytic conditions, or patients undergoing other abdominal surgery - but she does not clearly meet these.)
I would offer reassurance, explain the red-flag symptoms that should bring her back, and manage the dyspepsia on its own merits.
2. What specific advice would you give her about when to seek urgent help, and why does this matter?
Read the worked answer
She should be told to present urgently with:
- Constant severe right upper quadrant pain lasting more than a few hours, especially with fever - suggesting acute cholecystitis.
- Jaundice, pale stools, dark urine - suggesting common bile duct obstruction (stone in the duct).
- Fever with rigors and jaundice - the Charcot triad of cholangitis, which is an emergency.
- Severe epigastric/back pain with vomiting - possible gallstone pancreatitis.
This matters because the decision not to operate is a decision to watch and wait, which is only safe if the patient can recognise the complications that would change the plan. Documenting this advice and the reasoning protects both the patient and the clinician, and converts 'no operation' into active surveillance rather than neglect.
3. If she returns three months later with a single documented episode of biliary colic lasting two hours, how does your recommendation change?
Read the worked answer
This changes the picture from asymptomatic to symptomatic uncomplicated cholelithiasis (biliary colic). Once stones are genuinely symptomatic, the risk of recurrent attacks and of complications (cholecystitis, pancreatitis, choledocholithiasis) is meaningful, and laparoscopic cholecystectomy becomes the recommended treatment - it is the definitive way to prevent recurrence.
The reasoning: the natural history has now demonstrated that her stones can cause symptoms, and the balance of benefit versus operative risk shifts in favour of surgery. I would confirm the episode was typical biliary colic (postprandial, constant, right upper quadrant, settling over hours, no fever/jaundice), check liver function tests and consider imaging of the duct if there were any atypical features, then counsel her and list her for elective laparoscopic cholecystectomy, while advising her to present acutely if a further attack is prolonged, febrile, or associated with jaundice.
