Enterocolic Fistula caused by Acute Colitis in a Hemodialysis Patient / 대한내과학회지

Enterocolic fistulas are commonly associated with previous surgery, Crohn's disease, diverticulitis, radiation therapy, and malignancy. Here, we report a rare case of enterocolic fistula caused by acute colitis in a hemodialysis patient. A 62-year-old man on maintenance hemodialysis underwent a radical nephrectomy via a paramedian incision due to spontaneous right kidney rupture and was treated with prophylactic antibiotics. On the 16th day of antibiotic therapy, he complained of abdominal pain and diarrhea. Abdominal computed tomography (CT) and ascitic fluid culture revealed acute bacterial peritonitis and sigmoidoscopy showed acute colitis. After treating these diseases with adequate antibiotics, the abdominal pain and ascites were relieved, but the diarrhea persisted. Abdominal CT obtained 7 days later showed an enterocolic fistula. To our knowledge, this is the first case of enterocolic fistula due to acute colitis in Korea.

Lung Transplantation in a Patient with Pre-transplant Colonization of Extensively Drug-resistant Acinetobacter baumannii / 대한중환자의학회지

Colonization of the pre-transplant lung by multidrug-resistant bacteria affects short- and long-term outcomes of lung transplantation. However, there are no case reports on the colonization of a pre-transplant lung by drug-resistant Acinetobacter baumannii. We report a case of extensively drug resistant (XDR) A. baumannii colonization in the tracheobronchial tree that caused severe infectious complications after bilateral lung transplantation. A 23-year-old man diagnosed with bronchiolitis obliterans syndrome (BOS) 4 years earlier with a history of allogenic bone marrow transplantation for acute lymphoblastic leukemia was admitted to the hospital with dyspnea. Due to progressive hypercapnic respiratory failure, long-term mechanical ventilation was started after a tracheostomy was performed, and the patient underwent a bilateral lung transplantation to treat end-stage BOS. After the transplantation, the colonization of XDR A. baumannii caused severe bacterial pneumonia in the early postoperative period. Combined treatment with colistin and meropenem led to recovery from the pneumonia but caused drug-induced renal failure. Because many centers are willing to transplant candidates who are on mechanical ventilation or extracorporeal life support, the incidence of XDR A. baumannii colonization of pretransplant lungs is expected to increase. Further studies are needed to examine pre-transplant management strategies in patients colonized with XDR A. baumannii.
