Recently, City Ten Hospital successfully performed bedside common bile duct lithotripsy for a 97-year-old patient with acute septic obstructive cholangitis, enabling the old man to recover and extend his life. It is reported that the old man came to the hospital with confusion, high fever, yellow staining of the skin and mucous membranes all over the body, abdominal MRI found that the common bile duct was significantly dilated, and there was systemic multi-organ failure, especially cardiopulmonary failure, liver and kidney failure, and his condition was very critical. After careful study of the case, Deputy Director Wan Rong of the Department of Hepatobiliary and Pancreatic Medicine decided to perform ERCP (retrograde cholangiopancreatography via endoscopy) immediately. At the same time, because the patient was in critical condition and could not tolerate any movement, Deputy Director Wan Rong decided to perform bedside ERCP directly at the bedside. During the operation, a stone nearly 2 cm in size (normal human bile duct diameter is about 0.6 cm) was successfully removed from the patient’s common bile duct, and a large amount of purulent bile and sediment-like stones were drained out, thus allowing the common bile duct to be open again. The deputy director pointed out that biliopancreatic disease is a common disease in the elderly, often misdiagnosed as “stomach disease”, acute obstructive cholangitis is often accompanied by complex hepatobiliary pathological changes, the mortality rate is very high, the traditional treatment means “open surgery”, the patient pain, recovery is also slow ERCP technology has become the first choice for diagnosis and treatment of biliary tract diseases both at home and abroad, because it has the biggest advantage of eliminating the need for incision and relieving the pain like a gastroscopy. ERCP is a kind of retrograde cholangiopancreatography via endoscopy, which is a very mature technology. It is a contrast technique to inject contrast agent through the duodenal papilla under the endoscope, thus retrogradely displaying the pancreaticobiliary ducts, and is currently recognized as the gold standard for diagnosing pancreaticobiliary duct diseases. On the basis of ERCP, interventions such as duodenal papillary sphincterotomy (EST), endoscopic nasal bile drainage (ENBD) and endoscopic internal bile drainage (ERBD) can be performed, which are popular among patients because they do not require incision, are less invasive and have a much shorter hospital stay. At present, the Department of Hepatobiliary and Pancreatic Medicine of the Tenth Hospital has stepped into a new stage in ERCP diagnosis and treatment, especially under the leadership of Director Wan Rong, nearly 2000 ERCP procedures have been completed and rich experience has been accumulated, bringing gospel to the majority of gallstone patients!
