Case Details

Dr. Das Chakrabarty is the first of all a superior compassionate human being. One of my relative was admitted under him with end-stage liver disease. Patient had Cirhosis, GI bleeding, hepatic encephalopathy and ascites when first met the doctor. Under his treatment and care, the patient lived a quality life of more than three years where other doctors had predicted a prognosis of six months. Doctor did EVL banding twice and totally restricted GI bleeding. Ascites was also controlled by regular tests and diuretics. Myself being the patient`s primary care-giver, the doctor helped me to understand the disease in and out. Doctor was reachable at any point of time and listened to the issues with patience. At the end, the patient developed hepatocellular carcinoma. Even during the palliative care phase, when the patient was at home, the doctor visited and gave valuable suggestions like prognosis and patient`s will to continue further treatment. It is sad that the patient is no more with us, but I being a close relative of the patient will never forget the doctor`s contribution. It is priceless!!!!!
