RESUMEN
Background/Aims@#Sepsis-3 criteria and quick Sequential Organ Failure Assessment (qSOFA) have been advocated to be used in defining sepsis in the general population. We aimed to compare the Sepsis-3 criteria and Chronic Liver Failure-SOFA (CLIF-SOFA) scores as predictors of in-hospital mortality in cirrhotic patients admitted to the emergency department (ED) for infections. @*Methods@#A total of 1,622 cirrhosis patients admitted at the ED for infections were assessed retrospectively. We analyzed their demographic, laboratory, and microbiological data upon diagnosis of the infection. The primary endpoint was inhospital mortality rate. The predictive performances of baseline CLIF-SOFA, Sepsis-3, and qSOFA scores for in-hospital mortality were evaluated. @*Results@#The CLIF-SOFA score proved to be significantly better in predicting in-hospital mortality (area under the receiver operating characteristic curve [AUROC], 0.80; 95% confidence interval [CI], 0.78–0.82) than the Sepsis-3 (AUROC, 0.75; 95% CI, 0.72–0.77, P10%; this is the cutoff point for the definition of sepsis. @*Conclusions@#Among cirrhosis patients presenting with infections at the ED, CLIF-SOFA scores showed a better predictive performance for mortality than both Sepsis-3 criteria and qSOFA scores, and can be a useful tool of risk stratification in cirrhotic patients requiring timely intervention for infection.
RESUMEN
Background/Aims@#The coronavirus disease 2019 (COVID-19) outbreak caused numerous social and cultural changes, but few studies focused on their effects on gastroenterology (GI) fellowship training. This study evaluated the impact of COVID-19 on GI fellowship training. @*Methods@#A web-based questionnaire was sent out to GI fellows in Korea between 15 February and 15 March 2021. The questionnaire included questions regarding the characteristics of GI fellows, perception of COVID-19 outbreak, impact of COVID-19 outbreak, and telemedicine on the education of a GI fellowship. @*Results@#Among 111 answers, 94 respondents were analyzed. The GI fellows were provided with sufficient information about the COVID-19 outbreak (74.7%), well educated, and provided with personal protective equipment use (74.7% and 83.9%, respectively).On the other hand, outpatient schedule and volume decreased in 25.5% and 37.8% of respondents, respectively. Moreover, endoscopy sessions and volume decreased in 51.1% and 65.6% of respondents, respectively. As a result, 78.9% of respondents were concerned that the COVID-19 outbreak adversely affected their education. Telemedicine utilization was introduced during the COVID-19 outbreak, but only 20.0% and 10.6% of respondents agreed that telemedicine has benefits from the patient’s and doctor’s perspectives, respectively. In addition, only 25.9% of respondents were willing to continue telemedicine if adequately reimbursed, and 68.2% of respondents were concerned that it adversely affected their education. @*Conclusions@#The COVID-19 outbreak has adversely affected GI fellowship training in Korea for outpatient clinics, gastrointestinal endoscopy, educational conferences, and telemedicine. This study highlights that GI fellowship training needs more attention in the COVID-19 outbreak.

RESUMEN
Background/Aims@#Plug-assisted retrograde transvenous obliteration (PARTO) is widely used to manage gastric varices with a portosystemic shunt. It is not clear whether portal pressure and the incidence of complications increase after PARTO. The aim of this study was to determine the changes in portal pressure and the associated changes in liver func-tion, ascites, hepatic encephalopathy, and especially esopha-geal varix (EV) after PARTO. @*Methods@#From March 2012 to February 2018, 54 patients who underwent PARTO were analyzed retrospectively. The parameters collected included liver function and episodes of cirrhotic complications before and at 1 and 6 months after PARTO. @*Results@#The analysis of 54 patients showed improvement in liver function during the 6-month follow-up period (Model for End-Stage Liver Disease score: change from 11.46±4.35 to 10.33±2.96, p=0.021).Among these 54 patients, 25 patients were evaluated for their hepatic venous pressure gradient (HVPG) before and after PARTO (change from 12.52±3.83 to 14.68±5.03 mm Hg; p<0.001). Twenty-five patients with portal pressure mea-sured before and after PARTO were evaluated for risk factors affecting liver function improvement and EV deterioration. No factor associated with portal pressure was affected by liver function improvement. Post-PARTO portal pressure was a risk factor affecting EV deterioration (HVPG-post: odds ratio, 1.341; 95% confidence interval, 1.017 to 1.767; p=0.037). @*Conclusions@#The artificial blockade of the portosystemic shunt evidently leads to an increase in HVPG. Liver function was improved over the 6-month follow-up period. Portal pres-sure after PARTO was a significant risk factor for EV deterioration. Portal pressure measurement is helpful for predicting the patient’s clinical outcome.
RESUMEN
A subepithelial tumor-like esophageal carcinoma is rare. We report a case of an esophageal squamous cell carcinoma with lymph node metastasis presenting as a small subepithelial tumor. A 68-year-old man presented to our hospital complaining of hoarseness since last three months. Endoscopic examination revealed a 1 cm hard and fixed subepithelial tumor with surface erosion in the lower esophagus. A biopsy specimen was obtained using conventional forceps, and histopathological evaluation revealed few atypical squamous epithelial cells. Subsequent EUS demonstrated a homogeneous hypoechoic lesion in the deep mucosal layer. A CT scan of the chest showed a 3 cm mass in the right upper paratracheal area. EUS-guided fine needle biopsy of the lesion led to the diagnosis of squamous cell carcinoma with lymph node metastasis.

BACKGROUND/AIMS@#This study was conducted to clarify the sustained virological response (SVR) prediction ability of baseline and treatment-related factors in patients with chronic hepatitis C virus (HCV) infection.@*METHODS@#This retrospective study collected data at four tertiary referral hospitals between June 2004 and July 2012. Out of 476 patients, 330 treatment-naïve patients with chronic HCV infection were recruited. Pegylated interferon α-2a/-2b plus ribavirin was administered for either 24 or 48 weeks depending on the HCV genotype. The baseline and treatment-related predictive factors of SVR were evaluated by analyzing data measured before treatment (i.e., baseline) and during treatment.@*RESULTS@#SVR rates for genotypes 1 and 2 were 63% (97/154) and 79.5% (140/176), respectively (p = 0.001). Multivariate analysis for baseline factors revealed that young age (p = 0.009), genotype 2 (p = 0.001), HCV RNA level of 150 × 10³/µL (p 150 × 10³/µL. In multivariate analysis for treatment-related factors, SVR was associated with achievement of a rapid virological response (RVR; p < 0.001), treatment adherence of ≥ 80/80/80 (p < 0.001).@*CONCLUSIONS@#Young age, genotype 2, low HCV RNA level, RVR, and treatment adherence were significantly associated with SVR. In addition, platelet count was an independent predictive factor for SVR. Therefore, platelet count could be used to develop individualized treatment regimens and to optimize treatment outcomes in patients with chronic HCV infection.
RESUMEN
BACKGROUND/AIMS: The aim of this study was to investigate parameters that predict radiation-induced liver disease (RILD) following stereotactic body radiotherapy (SBRT) in patients with hepatocellular carcinoma (HCC) and to identify the clinical significance of RILD. METHODS: We retrospectively reviewed the medical records of 117 HCC patients who were treated by SBRT from March 2011 to February 2015. RILD was defined as elevated liver transaminases more than five times the upper normal limit or a worsening of Child-Pugh (CP) score by 2 within 3 months after SBRT. All patients were assessed at 1 month and every 3 months after SBRT. RESULTS: Median follow-up was 22.5 months (range, 3 to 56) after SBRT. RILD was developed in 29 of the 117 patients (24.7%). On univariate analysis, significant predictive factors of RILD were pretreatment CP score (p < 0.001) and normal liver volume (p = 0.002). Multivariate analysis showed that CP score was a significant predictor of RILD (p < 0.001). The incidence of RILD increased above a CP score of 6 remarkably. The rate of recovery from RILD decreased significantly above a CP score of 8. Survival analysis showed that CP score was an independent prognostic factor of overall survival (p = 0.001). CONCLUSIONS: CP score is a significant factor to predict RILD in patients with chronic liver disease. RILD can be tolerated by patients with a CP score ≤ 7. However, careful monitoring of liver function is needed for patients with a CP score 7 after SBRT.

In hepatocellular carcinoma (HCC), surgical resection or local ablation therapy is limited because of severe liver dysfunction or tumor location. Transarterial chemoembolization (TACE) has beed used widely as palliative treatment. Stereotactic Body Radiotherapy (SBRT) is a more recent and effective treatment for early stage HCC. We report a case with small HCC with complete response by TACE combined with SBRT.

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is one of the severe complications of liver cirrhosis. Early detection of high-risk patients is essential for prognostic improvement. The aim of this study is to investigate the predictive factors related to in-hospital mortality in patients with SBP. METHODS: This was a retrospective study of 233 SBP patients (181 males, 52 females) who were admitted to four tertiary referral hospitals between August 2002 and February 2013. The patients' laboratory and radiologic data were obtained from medical records. The Child-Turcotte-Pugh (CTP) score and model for end-stage liver disease sodium model (MELD-Na) scores were calculated using the laboratory data recorded at the time of the SBP episode. RESULTS: The causes of liver cirrhosis were hepatitis B (44.6%), alcohol (43.8%), hepatitis C (6.0%), and cryptogenic cirrhosis (5.6%). The mean MELD-Na and CTP scores were 27.1 and 10.7, respectively. Thirty-one of the patients (13.3%) died from SBP in hospital. Multivariate analysis revealed that maximum creatinine level during treatment was a statistically significant factor for in-hospital mortality (P = 0.005). The prognostic accuracy of the maximum creatinine level during treatment was 78.0% (P < 0.001). The optimal cutoff point for the maximum serum creatinine was 2 mg/dL (P < 0.001). CONCLUSION: The follow-up creatinine level during treatment is an important predictive factor of in-hospital mortality in cirrhotic patients with SBP. Patients with SBP and a serum creatinine level during treatment of ≥ 2.0 mg/dL might have a high risk of in-hospital mortality.

RESUMEN
BACKGROUND/AIMS: The optimal timing for discontinuing oral antiviral therapy in patients with HBeAg-positive chronic hepatitis B (CHB) is unclear. The aim of our study was to investigate sustained remission after stopping antiviral therapy in patients with HBeAg-positive CHB. METHODS: We analyzed the medical records of 58 patients who were HBeAg-positive and had discontinued antiviral therapy. Antiviral therapy was discontinued after HBeAg seroconversion and HBV DNA negativity for 6-12 months with consolidation therapy. Virologic relapse was defined as an increase in serum HBV DNA >2,000 IU/mL. RESULTS: No difference was observed between the virologic non-relapse and virologic relapse groups in baseline HBV DNA level (p=0.441) or duration of seroconversion (p=0.070). Time-to-undetectable HBV DNA during treatment was shorter in the virologic non-relapse group (29 patients) compared to the relapse group (29 patients) (4.9+/-2.6 vs. 13.2+/-12.7 months; p or =18 months, p=0.020) and early virologic response (HBV DNA <20 IU/mL) at six months during antiviral therapy (p=0.017) were significant predictors for sustained remission. CONCLUSIONS: A consolidation period of at least 18 months and early virological response at six months during antiviral therapy were associated with sustained remission in patients with HBeAg-positive CHB after treatment.

BACKGROUND/AIMS: Therapies involving bone-marrow-derived mesenchymal stem cells (BM-MSCs) have considerable potential in the management of hepatic disease. BM-MSCs have been investigated in regenerative medicine due to their ability to secrete various growth factors and cytokines that regress hepatic fibrosis and enhance hepatocyte functionality. The aim of this study was to determine the antifibrosis effect of BM-MSCs on activated hepatic stellate cells (HSCs) and the mechanism underlying how BM-MSCs modulate the function of activated HSCs. METHODS: We used HSCs in both direct and indirect co-culture systems with BM-MSCs to evaluate the antifibrosis effect of BM-MSCs. The cell viability and apoptosis were evaluated by a direct co-culture system of activated HSCs with BM-MSCs. The activations of both HSCs alone and HSCs with BM-MSCs in the direct co-culture system were observed by immunocytochemistry for alpha-smooth muscle actin (alpha-SMA). The levels of growth factors and cytokines were evaluated by an indirect co-culture system of activated HSCs with BM-MSCs. RESULTS: The BM-MSCs in the direct co-culture system significantly decreased the production of alpha-SMA and the viability of activated HSCs, whereas they induced the apoptosis of activated HSCs. The BM-MSCs in the indirect co-culture system decreased the production of transforming growth factor-beta1 and interleukin (IL)-6, whereas they increased the production of hepatocyte growth factor and IL-10. These results confirmed that the juxtacrine and paracrine effects of BM-MSCs can inhibit the proliferative, fibrogenic function of activated HSCs and have the potential to reverse the fibrotic process by inhibiting the production of alpha-SMA and inducing the apoptosis of HSCs. CONCLUSIONS: These results have demonstrated that BM-MSCs may exert an antifibrosis effect by modulating the function of activated HSCs.

BACKGROUND/AIMS: Tenofovir disoproxil fumarate (TDF) plays a pivotal role in the management of drug-resistant chronic hepatitis B. However, it remains unclear whether TDF-nucleoside analogue combination therapy provides better outcomes than TDF monotherapy. This study aimed to compare the efficacy of TDF monotherapy with that of TDF-nucleoside analogue combination therapy in patients with drug-resistant chronic hepatitis B. METHODS: This retrospective cohort study included 76 patients receiving TDF-based rescue therapy for more than 12 months. Suboptimal response was defined as serum HBV-DNA level of >60 IU/mL during prior rescue therapy. Multi-drug resistance was defined as the presence of two or more drug resistance-related mutations confirmed by mutation detection assay. The relationship between baseline characteristics and virologic response (HBV DNA <20 IU/mL) at 12 months were evaluated using logistic regression analysis. RESULTS: Fifty-five patients (72.4%) were suboptimal responders to prior rescue therapy, and 26 (34.2%) had multi-drug resistance. Forty-two patients (55.3%) received combination therapy with nucleoside analogues. Virologic response at 12 months was not significantly different between the TDF monotherapy group and TDF-nucleoside analogue combination therapy group (p=0.098). The serum HBV DNA level was reduced to -4.49+/-1.67 log10 IU/mL in the TDF monotherapy group and to -3.97+/-1.69 log10 IU/mL in the TDF-nucleoside analogue combination therapy group at 12 months (p=0.18). In multivariate analysis, female sex (p=0.032), low baseline HBV-DNA level (p=0.013), and TDF monotherapy (p=0.046) were predictive factors for virologic response at 12 months. CONCLUSIONS: TDF monotherapy showed similar efficacy to that of TDF-nucleoside analogue combination therapy in patients with drug-resistant chronic hepatitis B.

BACKGROUND/AIMS: It is sometimes difficult to incise the distal papillary roof (PR) completely in patients with choledocholiths and choledochoduodenal fistula (CDF). The Iso-Tome(R) (MTW-Endoskopie W. Haag KG), which is helpful in preventing electrical leakage, has good orientation capabilities and can be easily placed at the orifice of the CDF or ampulla of Vater (AV). We aimed to evaluate the efficacy of endoscopic sphincterotomy (ES) with the Iso-Tome(R) for cutting the distal PR. METHODS: Between May 2003 and July 2012, 35 patients were analyzed retrospectively. The distal PR was cut downward and/or upward using the Iso-tome(R) until the pink intrapapillary mucosa was fully exposed. Downward incisions were performed from the opening of the CDF to the orifice of the AV; upward incisions were performed in reverse. RESULTS: Spontaneous or artificial CDF occurred in four and 31 patients, respectively. The technical and therapeutic success rates were 94.3% (33/35) and 94.3% (33/35), respectively. There was no case of electrical damage to the pink intrapapillary mucosa. Adverse events occurred in 2.9% (1/35; 1, mild bleeding) of patients. CONCLUSIONS: The new technique of ES with the Iso-tome(R) is feasible and useful for effectively incising the distal PR in patients with CDF and choledocholiths.

Q fever is a zoonosis caused by a Coxiella burnetii. Q fever is clinically variable, presenting as asymptomatic infection, pneumonia, hepatitis and endocarditis. Treatment of acute Q fever with doxycycline is usually successful. Autoantibodies, such as anti-mitochondrial antibodies, smooth muscle antibodies (SMA), anti-cardiolipin and lupus anticoagulant, often rise in acute Q fever infection. Some cases may occasionally meet the criteria for autoimmune disease like systemic lupus erythematosus. We report a first case of Q fever that may mimic systemic lupus erythematosus in Korea.

Radiofrequency ablation (RFA) has been accepted as a safe and effective treatment for unresectable hepatic tumors because of the advantages of a minimally invasive procedure and the local treatment effect. Although RFA can be performed safely in most patients, early and late complications related to mechanical or thermal damage may be observed at follow-up examination. Hemobilia is a very rare complication of RFA and most hemobilia is an immediate complication. However, delayed hemobilia is an even more rare complication after RFA and is known to be a fatal complication. We present a case of delayed fatal hemobilia after RFA for hepatocellular carcinoma.

Duodenal perforation associated with endoscopic retrograde cholangiopancreatography is very uncommon. However, it usually requires early diagnosis and surgical management. Perforations are commonly caused by endoscopic sphincterotomy, biliary or duodenal stent placement, guidewire-related causes, and endoscopy itself. Perforatioins can follow various clinical courses, and management depends on the cause of the perforation. Among the above causes, guidewire-induced perforation is very rare and related reports and analyses are limited. Herein we describe four cases of guidewire-induced periampullary perforation during endoscopic retrograde cholangiopancreatography, and analyze clinical characteristics and management.

Obscure gastrointestinal bleeding accounts for approximately 5% of all gastrointestinal bleeding. Angioectasia of the small bowel is the most common form of obscure gastrointestinal bleeding, while small bowel tumors are the second. Among small bowel tumors, primary duodenal cancer is uncommon and represents 0.3% of gastrointestinal tumors. However, primary duodenal cancer at the duodenal stump following Billroth II gastrectomy for stomach cancer is extremely rare, and have not been reported yet in Korea. We report the first case of a 74-year-old man with chronic anemia and recurrent melena, which was diagnosed as a primary duodenal adenocarcinoma developed in afferent loop. The primary lesion was successfully accessed under cap-fitted endoscopy, however final diagnosis was delayed due to the unusual anatomical site.
