title: Retroperitoneal abscess and acute acalculous cholecystitis after iatrogenic colon injury: report of a case.
abstract: 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.
