More than half of all doctors in the world do not have the surgery needed to treat gallstones, according to a new survey.
The survey, conducted by the International Journal of Gynaecology, found that more than a quarter of doctors surveyed had never had the gallbladder surgery needed for gallstones.
Only about a quarter, or 27 percent, had had a gallbladectomy in the past five years, the survey found.
The number of people with gallstones has tripled in the last 30 years, and the most common reason doctors give for a gallstone removal is an allergic reaction.
Gallstones can cause serious complications such as bleeding and scarring.
The report also revealed that around 20 percent of gallstones are left untreated and untreated complications, including blindness, may result.
Gallbladder surgeons, meanwhile, are increasingly relying on newer technology to treat the disease, which can lead to infections and a higher rate of scarring and bleeding.
The surgery is performed in a hospital or private clinic and the patient is referred to a surgeon who does the surgery.
The procedure is usually performed using a needle and a scalpel, and most patients are given an injection of a steroid.
The patient is then told to wear a mask, which covers the affected area and the surgeon uses a drill to extract the gallstone.
