Splenic artery steal syndrome (SASS) is a cause of graft hypoperfusion leading to the development of biliary tract complications, graft failure, and in some cases to retransplantation. Its management is still controversial since there is no universal consensus about its prophylaxis and consequently treatment. We present a case of SASS that occurred 48 hours after orthotopic liver transplantation (OLTx) in a 56-year-old male patient with alcoholic cirrhosis and severe portal hypertension, and who was successfully treated by splenic artery embolization. A literature search was performed using the PubMed database, and a total of 22 studies including 4,789 patients who underwent OLTx were relevant to this review. A prophylactic treatment was performed in 260 cases (6.2%) through splenic artery ligation in 98 patients (37.7%) and splenic artery banding in 102 (39.2%). In the patients who did not receive prophylaxis, SASS occurred after OLTx in 266 (5.5%) and was mainly treated by splenic artery embolization (78.9%). Splenic artery ligation and splenectomies were performed, respectively, in 6 and 20 patients (2.3% and 7.5%). The higher rate of complications registered was represented by biliary tract complications (9.7% in patients who received prophylaxis and 11.6% in patients who developed SASS), portal vein thrombosis (respectively, 7.3% and 6.9%), splenectomy (4.8% and 20.9%), and death from sepsis (4.8% and 30.2%). Whenever possible, prevention is the best way to approach SASS, considering all the potential damage arising from an arterial graft hypoperfusion. Where clinical conditions do not permit prophylaxis, an accurate risk assessment and postoperative monitoring are mandatory.

Purpose: To analyze the clinical spectrum of posttransplantation lymphoproliferative disorder (PTLD) after liver transplantation in children. Methods: From January 1988 to June 2009, we retrospectively reviewed the medical records of 8 PTLD cases among 148 pediatric patients underwent liver transplantation. The age at transplantation, time of presentation after transplantation, clinical manifestations, histologic diagnosis, results of EBV (Epstein-Barr virus) assessments, managements and outcomes of PTLD were investigated. Results: The prevalence of PTLD in liver transplant pediatric recipients was 5.4% (8 of 148). The mean age of patients was 25.4${\pm}$21.3 months (range 10 to 67 months). Seven of 8 patients (87.5%) underwent liver transplantation before 1 year of age. The common clinical presentations were persistent fever (8 of 8, 100%) and bloody diarrhea (6 of 8, 75%). PTLD was diagnosed with gastrointestinal endoscopic biopsies in five patients and surgical biopsies in three. Histologic findings showed early lesion in three patients, polymorphic in two, and monomorphic in three. Burkitt lymphoma and lymphoblastic lymphoma were found in two of 3 monomorphic patients. Seven of 8 patients were found with EBV-positive. Eight patients were treated with dose reduction of immunosuppressants and infusion of ganciclovir. Rituximab was added to four patients. PTLD were successfully managed in all patients except one who died of sepsis during chemotherapy. Conclusion: Major risk factor of PTLD was to undergo liver transplantation before 1 year of age. Continuous monitoring for EBV viral load and gastrointestinal endoscopic biopsy may be useful to early detection of PTLD.

Nocardia farcinia, an aerobic, gram-positive bacilli actinomycetes of the genus Nocardia, is an uncommon pathogen found in humans. The most common Nocardia infection sites are the lung, central nervous system, and skin. Even though hematogenous dissemination can occur, isolation of the organism from blood cultures is very rare. We report a case of Nocardia infection that was isolated on blood cultures. A 59-year-old male with a medical history that includes a liver transplantation 6-years prior due to hepatocellular carcinoma secondary to chronic hepatitis B, developed pneumonia and was transferred to Severance Hospital. At the time of admission, the patient's initial exam showed hypothermia, tachypnea, and hypotension. His chest radiograph showed severe pneumonia and a large abscess on left upper lobe. Under the presumptive diagnosis of bacterial pneumonia or other opportunistic infection, we started broad spectrum antibiotics. However, he developed Nocardia sepsis, rapidly deteriorated, and subsequently died.

The results of hepatic portojejunostomy in 34 patients with biliary atresia operated upon by one surgeon between May 1989 and December 1997 were analyzed. Eleven (32.3 %) patients were 60 days or younger, 14 patient (41.2 %) were between 60 and 90 days, and 9 (26.5 %) were over 90 days of age. Jaundice cleared in 20 cases (58.8 %). Three patients died of liver insufficiency, 2 were anicteric but died from esophageal variceal bleeding. Three patients died as a result of sepsis, heart failure and left kidney agenesis. Five patients were lost to follow-up. The five-year survival rate was 73.8 %. Two patients over 90 days of age, survived more than 5 years. Survival rates were not significantly related to the age at operation. We conclude that hepatic portojejunostomy should be considered as a primary surgical modality for biliary atresia, even at age 90 days or more. Early detection of esophageal varices and sclerotherapy may be necessary. Liver transplantation is necessary if hepatic failure develops.

Purpose: Intense multidisciplinary team effort is required for the intestinal rehabilitation of patients afflicted with the short bowel syndrome (SBS). These include enteral and parenteral nutrition (PN) support, monitoring of complications related to treatment, and considering further medical or surgical options for intestinal adaptation. Methods: In the Intestinal Rehabilitation Team (IRT) at the Samsung Medical Center, we have experienced 20 cases of adult SBS requiring multidisciplinary intestinal rehabilitation. This study is a retrospective review of the collected medical records. Results: Of the 20 subjects treated, 12 patients were male and 8 patients were female. At the time of referral to the IRT, the mean age was 51.5 years, and the mean body weight was 50.1 kg, which was 90% of the usual body weight. The diseases or operative managements preceding massive bowel resection were malignancy in 11 cases, cardiac surgery in 2 cases, trauma in 2 cases and one case, each of tuberculosis, corrosive esophagitis, atrial fibrillation, simultaneous pancreas and kidney transplantation, and perforated appendicitis. Of these, there were 14 survivals and 6 mortalities. The fatalities were attributed to progression of disease, intestinal failure-associated liver disease, and sepsis (unrelated to intestinal failure) (2 cases each). Among the 14 surviving patients, 8 patients have been weaned off PN, whereas 6 are still dependent on PN (mean PN dependence 36%). Conclusion: This paper reports the results of multidisciplinary intestinal rehabilitation of adult short bowel patients treated at the Samsung Medical Center. Further studies are required to improve survival and enteral tolerance of these patients.
