Severe acute cholecystitis successfully treated with endoscopic nasobiliary drainage tube insertion: A case report.

In this report, we present a case of a patient with bile peritonitis caused by gallbladder perforation associated with acute cholecystitis, which required intensive postoperative care. The patient was a woman in her 40s who presented with abdominal pain. Upon examination, she was diagnosed as having acute cholecystitis and bile peritonitis caused by gallbladder perforation. Subsequently, a partial cholecystectomy, omental pack, and drainage were performed. Initially, her bile duct enzyme levels improved; however, they subsequently increased again. An endoscopic nasobiliary drainage tube was inserted, and thereafter, a decrease in inflammatory response and bile duct enzyme levels was observed. During the course of treatment, respiratory failure and renal impairment occurred, necessitating mechanical ventilation management and continuous hemodiafiltration. In patients with severe acute cholecystitis, in addition to treating the underlying condition, it is crucial to perform procedures perioperatively, in anticipation of the development of additional organ dysfunctions postoperatively.
