This retrospective study evaluated lactate clearance (LC), measured at 6, 12, 18, and 24 hours after reperfusion, as a predictor of early allograft dysfunction (EAD) and short-term outcomes in patients receiving deceased donor liver transplantation. Of 181 transplant recipients, 44 (24.3%) developed EAD and had lower LCs than those who did not develop EAD. A receiver operating characteristic analysis showed that LC determined at 6 hours showed the highest area under curve value of 0.828 (95% confidence interval [CI]: 0.755-0.990) for predicting the development of EAD at a cutoff value of 25.8% with 76.7% sensitivity and 77.9% specificity. LC values that fell below the cutoff values were significantly associated with EAD in a multivariate analysis, with values at 6 hours having the highest adjusted odds ratio (11.891, 95% CI: 4.469-31.639). In-hospital and 6 month mortalities were higher in patients with LC values below the cutoffs compared with those above the cutoff values at each time point. Thus, LC calculated shortly after reperfusion of an allograft is significantly discriminative for the development of EAD and is associated with short-term prognosis after deceased donor liver transplantation.

Purpose The aim of this study is to investigate the effect of the surgical hospitalist system on postoperative outcomes and hospital costs for surgical patients. Methods We reviewed the medical records of 522 patients who were admitted to the divisions of colorectal and gastrointestinal surgery for operation from September to December 2017 at Severance Hospital, Yonsei University College of Medicine in Seoul, Korea. All patients were divided into 2 groups; one that was managed by surgical hospitalists group (HG) and another that was managed by non-hospitalist residents group (NHG) after elective surgery. Postoperative outcomes and hospital costs were analyzed for each group. Results Two hundred ninety-eight patients were managed by HG and 189 patients were managed by NHG after surgery. The length of hospital stay in the first group was shorter (9.6 ± 5.8 days vs. 12.2 ± 7.9 days, P < 0.001), the incidence of complications was lower (44.6% vs. 55.6%, P = 0.019), and the readmission rate was lower (3.0% vs. 6.9%, P = 0.046) in the HG than in the NHG. The difference in total hospital costs was not significant between the HG and the NHG (₩8,381,304 vs. ₩9,242,493, P = 0.559), but surgery-independent hospital costs were lower in the HG than in the NHG (₩3,020,873 vs. ₩3,923,308, P = 0.001). Conclusion The surgical hospitalist system reduced the length of hospital stay, the incidence of postoperative complications, and the readmission rates of surgical patients. This led to the effect of a reduction in total hospital costs.

Rationale: In living-donor liver transplantation (LDLT), the right lobe graft is commonly utilized to prevent small-for-size syndrome, despite the considerable donor morbidity. Conversely, the feasibility of the left lobe graft and the right posterior section graft in smaller-sized recipients is now commonly employed with comparable outcomes to right lobe grafts. The efficacy of the right anterior section graft has rarely been reported. Patient concerns: A 56-year-old man, a heavy alcoholic beverage drinker for 20 years, presented in the emergency department with massive ascites and lethargy. He was previously admitted twice due to bleeding esophageal varices. Diagnosis: He was diagnosed with hepatic encephalopathy coma due to alcoholic liver cirrhosis. The Child–Turcotte–Pugh score was 11 (class C), and the Model for End-stage Liver Disease score was 21.62. Intervention: A LDTL was offered to the patient as the best treatment option available. The patient's 26-year-old son was found to be the only donor-compatible candidate for the LDTL. Preoperatively, the right lobe of the donor occupied 76.2% of the total liver volume exposing the donor to a small residual liver volume. The right posterior section and left lobe volumes were insufficient, providing a graft-to-recipient weight ratio of 0.42% and 0.38%, respectively. However, the right anterior section could fulfill an acceptable GRWR of 0.83%. Thus, a living donor right anterior sectionectomy was performed. Outcomes: Clinical signs and symptoms and liver function improved following anterior section graft transplantation without complications. Lesson: The procurement of anterior section graft is technically feasible in selected patients, especially in high-volume liver centers.

Background: The shortage of doctors at night makes it difficult to execute complex tasks and deliver accurate decisions. Therefore, reducing the night shift physician's workload is essential for patient safety. This study aimed to observe the effect of daytime surgical hospitalists on the reduction in night shift physicians' workload by analyzing the volume of electronic orders generated at night for postoperative patients.Methods: A total of 9328 hospitalized patients who underwent colorectal or gastrointestinal surgery for more than 120 minutes were reviewed retrospectively. This study reviewed the nighttime volume difference of electronic orders between patients cared for by a daytime surgical hospitalist and patients cared for by a resident. Multiple logistic regression analysis was performed to analyze the risk factors of nighttime orders during hospitalization (dichotomous end point). Negative binomial regression analysis was also performed to analyze the volume of electronic orders as countable data, and the incident rate ratio was estimated (count end point). Results:The risk of the occurrence of nighttime electronic order for patients treated by a surgical hospitalist was lower than that of patients cared for by a resident (adjusted odds ratio, 0.616; 95% confidence interval, 0.558-0.682; P < 0.001). In the negative binomial regression analysis, the total volume of electronic orders at night was lower in patients cared for by a surgical hospitalist than in patients cared for by a resident (adjusted incident rate ratio, 0.653; 95% confidence interval, 0.623-0.685; P < 0.001). Conclusions:The introduction of daytime surgical hospitalists is associated with the lower workload of night shift physicians.
