PalgharA laparoscopic surgeon in Nashik removed 4,100 gallstones from a 43-year-old patient on Saturday. Yogesh Yewle runs a hardware shop in Nashik and had been complaining of intense abdominal pain since Thursday. After several tests confirmed gallstones, Dr Amit Sharad Kele, who runs Krishna Hospital, Nashik, operated on Ywele. Kele said each of the stones ranged 3mm to 4mm in diameter. After the surgery, which lasted for almost four hours, two of hospital staff members were asked to count the stones. It took them two hours to reach the final count of 4,100 gallstones. “The patient [Yewle] is responding to the treatment and will be discharged next week,” said Kele, adding obesity, diabetes, irregular food habits and cholesterol are reasons behind gallstone formation, which is becoming common in women.Commenting on similar cases, Kele said the world record for removing most number of gallstones belong to Dr ML Saha from West Bengal, who removed 11,950 gallstones in 2015. Kele said gallstones are made of cholesterol and a patient visits the doctor only after her or she is unable to bear abdominal pain. Surgery is the only option, he added. Severe gallstone disease can even lead to gallbladder cancer in 1 out of 1,000 patients.
