Acute
acalculous cholecystitis has a high mortality rate due to the difficulties in early diagnosis and high rate of complications like
empyema,
gangrene and perforation. We report a case of 20-year-old male with acute severe
pancreatitis, acute renal failure and acute peripancreatic fluid collection who was transferred to our department after blood filtration treatment in ICU. After percutaneous
catheter drainage for 20 hours, the patient got a high
fever. Computed tomography revealed retroperitoneal colon injury. In this case, percutaneous
catheter drainage was performed again and the
pus cavity was flushed regularly, after which the patient's state gradually improved. Unpredictably,
septic shock appeared on the 51(st) day. Repeated computed tomography revealed acute
acalculous cholecystitis and
abscess formation. After percutaneous transhepatic gallbladder catheterization and drainage, the patient got better gradually. Three months later the retroperitoneal
catheter was removed. Four months later, ultrasound examination showed normal gallbladder and the
catheter was removed.
