ABSTRACT
Purpose@#In June 2016, the Model for End-Stage Liver Disease (MELD) score was employed in South Korea instead of the Child-Turcotte-Pugh (CTP) score. This study compared the outcomes of deceased donor liver transplantation (DDLT) before and after the MELD system application. @*Methods@#This retrospective study reviewed 48 patients who underwent DDLT for end-stage liver disease at a single tertiary referral center between January 2014 and December 2018. The patients were categorized into the pre-MELD (22 patients) and post-MELD (26 patients) groups. The demographics, postoperative outcomes, and overall survival time were evaluated between the 2 groups. @*Results@#The 2 groups had no differences in age, sex, ABO type, etiology for liver transplantation, CTP-score, operation time, cold ischemic time, and amount of red blood cell transfusion, although their MELD score differed significantly (postMELD group, 36.2 ± 4.9; pre-MELD group, 27.7 ± 11.8; P < 0.001). The post-MELD group has longer intensive care unit stay (11.2 ± 9.5 days vs. 5.7 ± 4.5 days, P = 0.018) and hospital stay than the pre-MELD group (36.8 ± 26 days vs. 22.8 ± 9.3 days, P = 0.016). The 1-year survival rate was lower in the post-MELD group (61.5% vs. 86.4%, P = 0.029). @*Conclusion@#After MELD allocation, patients with high MELD scores had increased DDLT and consequently required a longer recovery time, which could negatively affect survival. According to the experience of a small-volume center, these problems were related to both severe organ shortages in South Korea and MELD allocation.
ABSTRACT
Purpose@#Laparoscopic sleeve gastrectomy (SG) is now frequently performed as a definitive bariatric procedure. The aim of the study was to evaluate the detailed morphology of remnant stomachs after SG with respect to volume and sleeve migration. @*Materials and Methods@#We performed a retrospective review of prospectively collected data on patients that completed a 12-month postop examination, which included CT volumetry of sleeve, and a questionnaire that addressed postop food tolerance. CT volumetry study included total sleeve volume (TSV), tube volume (TV), antral volume (AV), tube/antral volume ratio (TAVR), and the presence of intrathoracic sleeve migration (ITSM). @*Results@#Fifty-five patients were included in this retrospective study. Mean %TWL (% total weight loss) at 12 months postop was 32.8% (14.3-55.5), and mean TSV, TV, AV, and TAVR were 166.6±63.3 ml, 68.9±35.4 ml, 97.7±42.9 ml, and 0.8±0.6 respectively. TSV was not correlated significantly with %TWL at 12 months postop (r=−0.069, P=0.619). Fourteen patients (14/55, 25.5%) showed ITSM by CT. Patients with ITSM had a significantly lower mean GER score (5.1±2.0 vs. 7.3±2.0, P=0.001), a lower total food tolerance score (21.6±3.8 vs. 24.4±4.6, P=0.048), and a higher proportion showed suboptimal weight loss (35.7% vs. 9.8%, P=0.023). @*Conclusion@#Mean TSV was not found to be significantly correlated with %TWL at 12 months postop.Patients with suboptimal weight loss had higher mean TAVR, and the presence of ITSM indicated more frequent GER symptoms, lower food tolerance, and a higher probability of suboptimal weight loss.
