An 89-year-old resident of Makhachkala went to hospital with severe abdominal pain - doctors diagnosed her with acute cholecystitis. The patient's condition worsened. Surgeons decided to perform an emergency operation to remove a gallbladder with a hen egg sized stone inside.

"Stones are formed due to stagnation of bile and metabolic disorders. A person may not even be aware of the disease for a long time, until sharp pains appear in the abdomen” - surgeon Damada Damadaev explains.
