How To Treat Gallstone From Bile Duct Despite Being Treated For Cholangitis?

Hello Doctor,I am Mahmudul Haque S/O,M. Aminul Haque(age of 79). Currently my father has got Cholangitis. The doctor(Interventional Gastroenterologist) has suggested for ERCP to remove the gallstone from the bile duct. Before the ERCP it is found(by echo) that his heart bit is 45 and the cardiac anesthetist has given his opinion that it is little bit risky for giving sleeping medicine for the surgery (ERCP) at that point finally we have denied for going ERCP (considering the health conditions, age and all other risk factors like as cardiac attack,infections and infection-in Pancreas for using dye).Now, the day of 3rd of April his bilirubin has reduced to 1.35 from 4.6; Diabetic rate is always average 7-8 and BP is around 130/70.Now we are thinking for Homeopathic treatment to remove or dissolve the gall stone from the common upstream bile duct as stated in the MRCP report (as attached here with for your perusal).Could you please let us know the possibility of removing or dissolving the gall stones from the bile duct.Would be grateful to you for your feedback.Thanking you for giving time.Mahmudul Haque YYYY@YYYY ; YYYY@YYYY Cell:0000
