Symptoms May Worsen If Left Untreated
Look out for these common signs of gallstones — early detection can prevent complications.
Sudden, sharp pain in the upper right or middle abdomen (“gallbladder attack”)
Pain that may spread to the back or right shoulder Nausea or vomiting
In severe cases: fever, jaundice (yellow skin/eyes)
Indigestion, bloating, or discomfort after fatty meals
Nausea or vomiting
When is surgery needed?
Not all gallstones require surgery — some people have them without any symptoms (“silent gallstones”). But surgery (usually cholecystectomy, gallbladder removal) is needed if gallstones cause:
-
Repeated pain attacks (biliary colic) – sharp pain in the upper right abdomen, especially after fatty meals.
-
Complications such as:
-
Cholecystitis → gallbladder infection/inflammation (pain, fever, nausea).
-
Choledocholithiasis → gallstones blocking the bile duct, causing jaundice or infection.
-
Gallstone pancreatitis → when stones block the pancreatic duct, leading to life-threatening inflammation.
-
Large gallstones (usually >2 cm) – higher risk of complications.
-
Gallbladder polyps or suspicion of cancer.
-
Weakened immune system (higher risk if infection develops).
-
Surgical Techniques for Gallstones
Laparoscopic Cholecystectomy (Keyhole Surgery)
-
The most common method worldwide. Surgeons make 3–4 small cuts in the abdomen, insert a camera and instruments, and remove the gallbladder.
-
Benefits of Laparoscopic white box
Open Cholecystectomy
-
A larger incision is made in the abdomen to remove the gallbladder.
-
Usually done if:
-
Gallbladder is severely inflamed, scarred, or infected
-
Recovery takes longer (hospital stay of several days, full recovery in 4–6 weeks)
