RESUMEN
BACKGROUND AND AIMS: Placement of a self-expandable metal stent (SEMS) across the duodenal major papilla carries a risk of duodenobiliary reflux (DBR). The suprapapillary method of stent placement may reduce DBR and improve stent patency compared with the transpapillary method. This study compared the clinical outcomes between the suprapapillary and transpapillary methods for distal malignant biliary obstruction (DMBO). METHODS: Between January 2021 and January 2023, consecutive patients with DMBO from 6 centers in South Korea were randomly assigned to either the suprapapillary arm or transpapillary method arm in a 1:1 ratio. The primary outcome was the duration of stent patency, and secondary outcomes were the cause of stent dysfunction, adverse events, and overall survival rate. RESULTS: Eighty-four patients were equally assigned to each group. The most common cause of DMBO was pancreatic cancer (50, 59.5%), followed by bile duct (20, 23.8%), gallbladder (11, 13.1%), and other cancers (3, 3.6%). Stent patency was significantly longer in the suprapapillary group (median, 369 days [interquartile range, 289-497] vs 154 days [interquartile range, 78-361]; P < .01). Development of DBR was significantly lower in the suprapapillary group (9.4% vs 40.8%, P < .01). Adverse events and overall survival rate were not significantly different between the 2 groups. CONCLUSIONS: The placement of SEMSs using the suprapapillary method resulted in a significantly longer duration of stent patency. It is advisable to place the SEMS using the suprapapillary method in DMBO. Further studies with a larger number of patients are required to validate the benefits of the suprapapillary method.

RESUMEN
OBJECTIVES: There are no recommendations regarding the optimal puncture site in endoscopic ultrasound-guided fine needle biopsy (EUS-FNB). This multicenter randomized prospective study compared the diagnostic accuracy and histological findings according to the sampling site for pancreatic masses larger than 3 cm. METHODS: Consecutive patients with pancreatic masses larger than 3 cm indicated for EUS-FNB were included in the study. Patients were randomly assigned to two groups for the initial puncture site (central vs. peripheral sampling of the masses). A minimum of four passes were performed, alternating between the center and the periphery. The primary outcome was diagnostic accuracy. RESULTS: A total of 100 patients were equally divided into the central group and the peripheral group. The final diagnosis revealed malignancy in 95 patients (pancreatic cancer [n = 89], neuroendocrine tumor [n = 4], lymphoma [n = 1], metastatic carcinoma [n = 1]), and benign conditions in five patients (chronic pancreatitis [n = 4], autoimmune pancreatitis [n = 1]). There was no significant difference in diagnostic accuracy between the puncture sites. However, combining samples from both areas resulted in higher diagnostic accuracy (97.0%) compared to either area alone, with corresponding values of 88.0% for the center (P = 0.02) and 85.0% for the periphery (P = 0.006). CONCLUSIONS: Both central sampling and peripheral sampling showed equivalent diagnostic accuracy in detecting malignancy. However, combining samples from both areas generated superior diagnostic yield compared to using either sampling site alone. For pancreatic masses larger than 3 cm, it is advisable to consider sampling from various areas of the masses to maximize the diagnostic yield.
RESUMEN
BACKGROUND AND AIMS: Immunoglobulin G4-related sclerosing cholangitis (IgG4-SC) is considered a biliary manifestation of IgG4-related diseases. However, there has been a controversy on the clinical outcomes according to the location of the involved bile duct. We therefore compared the clinical outcomes and long-term prognosis of IgG4-SC with proximal bile duct involvement (proximal IgG4-SC) and IgG4-SC with distal bile duct involvement (distal IgG4-SC). METHODS: We reviewed the data of patients with IgG4-SC that were prospectively collected at 10 tertiary centers between March 2002 and October 2020. Clinical manifestations, outcomes, association with autoimmune pancreatitis (AIP), steroid-responsiveness, and relapse of IgG4-SC were evaluated. RESULTS: A total of 148 patients (proximal IgG4-SC, n = 59; distal IgG4-SC, n = 89) were analyzed. The median age was 65 years (IQR, 56.25-71), and 86% were male. The two groups were similar in terms of jaundice at initial presentation (51% vs 65%; P = 0.082) and presence of elevated serum IgG4 (66% vs 70%; P = 0.649). The two groups showed significant differences in terms of steroid-responsiveness (91% vs 100%; P = 0.008), association with AIP (75% vs 99%; P = 0.001), and occurrence of liver cirrhosis (9% vs 1%; P = 0.034). During a median follow-up of 64 months (IQR, 21.9-84.7), the cumulative relapse-free survival was significantly different between the two groups (67% vs 79% at 5 years; P = 0.035). CONCLUSIONS: Relapse of IgG4-SC frequently occurred during follow-up. Proximal IgG4-SC and distal IgG4-SC had different long-term outcomes in terms of steroid-responsiveness, occurrence of liver cirrhosis, and recurrence. It may be advantageous to determine the therapeutic and follow-up strategies according to the location of bile duct involvement.

BACKGROUND: Common bile duct (CBD) stone is one of the most frequent biliary diseases. Recurrence after the complete removal of CBD stones is high, and we aim to evaluate the rate and risk factors for symptomatic recurrence of CBD stones after endoscopic retrograde cholangiopancreatography (ERCP). METHODS: We, retrospectively, reviewed the database of patients who underwent ERCP for CBD stones and subsequent cholecystectomy between January 2015 and December 2017 at a tertiary hospital. The recurrence of symptomatic CBD stones was defined as the presence of a CBD stone with related symptoms at least 6 months after the ERCP procedure. The primary outcomes were recurrence of symptomatic CBD stones and its risk factors. RESULTS: Among the 362 enrolled patients, 60 experienced a symptomatic recurrence of CBD stones between 6 months and 5 years after the procedure. The mean duration of follow-up was 32.3 ± 8.1 months. The patients with recurrences were older and had a longer follow-up duration. Low insertion of the cystic duct (HR = 2.893, p = 0.016), distal CBD angulation (HR = 1.015, p = 0.034), maximum CBD diameter (HR = 1.070, p = 0.012), number of ERCP sessions at first admission (HR = 1.558, p = 0.032), and cannulation time (HR = 1.030, p = 0.008) were the independent risk factors for symptomatic recurrent CBD stones. CONCLUSIONS: Patients with risk factors, especially those with low cystic duct insertion, are more prone to symptomatic recurrent CBD stones and should be followed more carefully.

BACKGROUND: Pancreatic neuroendocrine neoplasms (PNENs) show heterogeneous biological behavior, and most small PNENs show indolent features. Consequently, selected cases can be considered for observation only, according to the National Comprehensive Cancer Network guideline, however, supporting clinical evidence is lacking. We investigated the clinical course of small PNENs and their risk factors for malignant potential. METHODS: A total of 158 patients with small pathologically confirmed PNENs ≤2 cm in initial imaging were retrospectively enrolled from 14 institutions. The primary outcome was any metastasis or recurrence event during follow-up. RESULTS: The median age was 57 years (range, 22-82 years), and 86 patients (54%) were female. The median tumor size at initial diagnosis was 13 mm (range, 7-20 mm). PNENs were pathologically confirmed by surgery in 137 patients and by EUS-guided fine needle aspiration biopsy (EUS-FNAB) in 21 patients. Eight patients underwent EUS-FNAB followed by surgical resection. The results of WHO grade were available in 150 patients, and revealed 123 grade 1, 25 grade 2, and 2 neuroendocrine carcinomas. A total of 145 patients (92%) underwent surgical resection, and three patients had regional lymph node metastasis. During the entire follow-up of median 45.6 months, 11 metastases or recurrences (7%) occurred. WHO grade 2 (HR 13.97, 95% CI 2.60-75.03, p = 0.002) was the only predictive factor for malignant potential in multivariable analysis. CONCLUSIONS: WHO grade is responsible for the malignant potential of small PNENs ≤2 cm. Thus, EUS-FNAB could be recommended in order to provide early treatment strategies of small PNENs.

BACKGROUND: The comparative efficacy of bariatric endoscopic procedures has not been completely elucidated. We aimed to comprehensively evaluate the efficacy of bariatric endoscopic procedures. METHODS: We searched for randomized controlled trials investigating the efficacy of bariatric endoscopic procedures, including the use of an intragastric balloon, duodenal-jejunal bypass liner (DJBL), aspiration therapy, primary obesity surgery endoluminal (POSE) procedure, and botulinum toxin injection to the stomach. Network meta-analyses were performed to determine the percentage of weight loss (%weight loss) and percentage of excess weight loss (%EWL). RESULTS: 22 studies with 2141 patients were included in the meta-analysis. Most endoscopic procedures showed superior efficacy in terms of %weight loss compared with the control (mean difference [MD] [95â% confidence interval (CI)]: aspiration therapy 10.4â% [7.0â% to 13.7â%]; fluid-filled balloon 5.3â% [3.4â% to 7.2â%]; POSE 4.9â% [1.7â% to 8.2â%]; and DJBL 4.5â% [1.4â% to 7.7â%]). In terms of %EWL, aspiration therapy, fluid-filled balloon, POSE, and DJBL were superior to the control (MD [95â%CI]: 27.3â% [15.3â% to 39.3â%]; 22.4â% [15.4â% to 29.4â%]; 15.3â% [2.5â% to 28.0â%]; and 13.0â% [4.9â% to 21.2], respectively). The gas-filled balloon and botulinum toxin injection did not show a significant difference in %weight loss or %EWL compared with the control. For the fluid-filled balloon, the %EWL and %weight loss tended to decrease after balloon removal at 6 months after the procedure. CONCLUSION: All bariatric endoscopic procedures, except for gas-filled balloon and botulinum toxin injection to the stomach, showed superior short-term efficacy in terms of %weight loss or %EWL compared with lifestyle modification.

BACKGROUND: There are limited studies focusing on liver abscess with negative microbiological cultures. This study evaluated the clinical and prognostic differences of patients with culture-negative liver abscess (CNLA) compared to those with a positive culture (CPLA) and compared these factors between K. pneumoniae liver abscess (KLA) and E. coli liver abscess (ELA). METHODS: A retrospective study of the patients who admitted with a liver abscess at two tertiary hospitals in Korea from 2012 to 2016 was performed. RESULTS: Among a total of 402 patients with liver abscess, 61.2% had positive cultures. K. pneumoniae (n = 133) was the most common cause, followed by E. coli (n = 74). Patients with CPLA were significantly older (p = 0.02) and more frequently had cholelithiasis or biliary tract disease (p = 0.001) compared to patients with CNLA. In-hospital mortality (p = 0.63) and recurrence (p = 0.77) were no different between the two groups. The length of hospital stay was significantly longer in patients with CPLA (p = 0.03) compared with those with CNLA. Subgroup analysis for patients who received 3rd generation cephalosporins empirically showed that in-hospital mortality (p = 0.18) and recurrence (p = 0.27) were not also significantly different. Cholelithiasis, or biliary tract disease (p = 0.001), liver disease (p = 0.001), malignancy (p = 0.0001), and ESBL production (p = 0.0001) were found more frequently in patients with ELA compared with those with KLA. CONCLUSIONS: The prognosis of the CNLA patients was similar to that of the CPLA patients, although the length of hospital stay was shorter in the CNLA patients. The epidemiologic and clinical characteristics of the ELA patients are somewhat different than those of the KLA patients.

BACKGROUND: The forward-viewing endoscope has been increasingly used to perform endoscopic retrograde cholangiopancreatography (ERCP) in patients who underwent Billroth II gastrectomy. This study intended to assess efficacy and safety of the forward-viewing endoscope for ERCP in Billroth II gastrectomy patients compared with conventional side-viewing endoscope using a systematic review and meta-analysis. METHODS: A systematic review was conducted for studies that evaluated the outcomes of ERCP for patients with Billroth II gastrectomy. Random-effect model meta-analyses with subgroup analyses were conducted. The methodological quality of the included publications was evaluated using the risk of bias assessment tool for non-randomized studies. The publication bias was assessed. RESULTS: In total, 25 studies (1 randomized, 18 retrospective, 1 prospective, and 5 case series studies) with 2446 patients (499 forward-viewing and 1947 side-viewing endoscopes) were analyzed. The pooled afferent loop intubation rate was higher with the forward-viewing endoscope (90.3%, 95% confidence interval (CI) 85.6-93.6 vs. 86.8%, 95% CI 82.8-89.9%). The pooled selective cannulation rate was higher with the side-viewing endoscope (92.3%, 95% CI 88.0-95.2 vs. 91.1%, 95% CI 87.2-93.9%). The pooled bowel perforation rate was higher with the side-viewing endoscope (3.6%, 95% CI 2.3-5.7 vs. 3.0%, 95% CI 1.7-5.3%). The pooled pancreatitis rate was higher with the forward-viewing endoscope (5.4%, 95% CI 3.6-8.0 vs. 2.5%, 95% CI 2.3-5.7%). The pooled bleeding rate was higher with the forward-viewing endoscope (3.0%, 95% CI 1.6-5.5 vs. 2.0%, 95% CI 1.4-3.0%). The heterogeneity among the studies was not significant. The publication bias was minimal. CONCLUSION: This meta-analysis indicates that the forward-viewing endoscope is as safe and effective as conventional side-viewing endoscope for ERCP in patients with Billroth II gastrectomy.

As alcohol induces change in frontal cortex primarily involved in cognition, cognitive function may be different between viral and alcoholic liver cirrhosis (LC). This study aimed to determine the differences of cognitive function between viral and alcoholic compensated LC. From October 2011 to March 2013, 80 patients (viral: 37; alcohol: 43) with compensated LC were prospectively enrolled. Neuropsychological functions including attention, language, visuospatial, verbal memory, visual memory, and frontal/executive function were evaluated between two groups and compared with age-matched normal group (n = 1000). Cumulative incidence rate of overt hepatic encephalopathy (HE) was calculated. In the comparison with normal group, both two groups showed decreased memory function, frontal/executive function, and Korea-Mini Mental Status Examination. In the analysis of two groups, memory function by Verbal Learning Test (recognition: 20.1 ± 3.6 and 17.8 ± 4.8, p = 0.022), visuospatial function by Ray-Complex Figure Copy Test (recognition: 19.0 ± 2.6 and 17.3 ± 4.0, p = 0.043), frontal/executive function by Controlled Oral Ward Association (semantic: 17.1 ± 6.9 and 12.7 ± 6.9, p = 0.004), and the Korea-Mini Mental Status Examination (27.5 ± 1.9 and 26.2 ± 3.1, p = 0.03) showed low scores in alcoholic compensated LC patients. The 1-, 2-, and 3-year cumulative incidence rates of overt HE were 23%, 26%, and 26% and 33%, 43%, and 49% in the viral and alcoholic compensated LC group, respectively (p = 0.033). Impaired memory and frontal lobe executive functions and early development of overt HE were more common in patients with alcoholic LC. For patients with alcoholic LC, more integrated tests for early detection of minimal HE and intensive treatment should be considered to prevent overt HE.

BACKGROUND: Controversies persist regarding the effect of intragastric injection of botulinum toxin A for the treatment of obesity. OBJECTIVE: To assess the efficacy of intragastric botulinum toxin injection for the treatment of obesity. DESIGN: A systematic literature review was conducted by using the core databases. Pre- and posttreatment body weight data were extracted and analyzed by using Hedges' g. A random-effects model was applied. The methodological quality of the enrolled studies was assessed by the risk of bias table and Newcastle-Ottawa Scale. Publication bias was evaluated via the funnel plot, trim and fill method, Egger's test, and rank correlation test. SETTING: Meta-analysis of 8 studies. PATIENTS: A total of 115 patients (79 treated vs 36 placebo). INTERVENTION: Intragastric botulinum toxin A injection. MAIN OUTCOME MEASUREMENTS: Hedges' g, calculated from pre- and posttreatment body weight data and comparison of body weight changes between treatment and placebo group. RESULTS: The treatment group was associated with weight loss in a pre/post comparative approach and compared with the placebo group (Hedges' g: -0.443; 95% confidence interval, -0.845 to -0.040; P = .031; and Hedges' g: -0.521; 95% confidence interval, -0.956 to -0.085; P = .019). Wide area injection including the fundus or body rather than the antrum only was associated with weight loss. Multiple injections (>10) were associated with weight loss. However, a large amount of botulinum toxin A (500 IU) was not associated with weight loss. Sensitivity analyses showed consistent results. Meta-regression for the botulinum toxin A dose and number of injections showed consistent results. Publication bias was not detected. CONCLUSION: In this analysis, intragastric injection of botulinum toxin A is effective for the treatment of obesity.

BACKGROUND AND AIM: The aim of this study was to assess the therapeutic effect of mosapride in patients with functional dyspepsia (FD). METHODS: Randomized controlled trials (RCTs) of mosapride for the treatment of FD performed between 2002 and 2013 were identified from databases. Symptom response rates were extracted and analyzed using risk ratios (RRs). A random effect model was applied based on Higgins I(2) tests. Publication bias was evaluated using a funnel plot, Egger's test, trim and fill, and the rank correlation test. RESULTS: In total, 13 RCTs, which included 1091 mosapride-treated patients and 1129 control patients (on placebo or other drugs), were identified and analyzed. Overall, mosapride showed an RR of 0.999 (95% confidence interval [CI]: 0.869-1.150, P = 0.992) for improving global efficacy or symptom-based scores. In a sensitivity analysis of the high-quality RCTs, mosapride showed an RR of 1.114 (95% CI: 1.011-1.227, P = 0.029). However, in the studies using the Rome III criteria for the diagnosis of FD, mosapride showed an RR of 0.906 (95% CI: 0.807-1.016, P = 0.092). In the studies having funding source, mosapride showed an RR of 1.131 (95% CI: 1.028-1.244, P = 0.012), whereas an RR of 0.966 (95% CI: 0.896-1.042, P = 0.367) was observed in the studies without funding source. Publication bias was not detected. CONCLUSION: In this analysis, we could not find a significant effect of mosapride on FD. Inconsistent diagnostic criteria for FD and different assessment outcomes are causes of heterogeneity. Further studies using common validated outcomes or questionnaires and high-quality RCTs will elucidate the real effect of this medication on FD.

Controversies persist regarding the effect of Helicobacter pylori eradication on the development of metachronous gastric cancer after endoscopic resection of early gastric cancer (EGC). The aim of this study was to assess the efficacy of Helicobacter pylori eradication after endoscopic resection of EGC for the prevention of metachronous gastric cancer. A systematic literature review and meta-analysis were conducted using the core databases PubMed, EMBASE, and the Cochrane Library. The rates of development of metachronous gastric cancer between the Helicobacter pylori eradication group vs. the non-eradication group were extracted and analyzed using risk ratios (RRs). A random effect model was applied. The methodological quality of the enrolled studies was assessed by the Risk of Bias table and by the Newcastle-Ottawa Scale. Publication bias was evaluated through the funnel plot with trim and fill method, Egger's test, and by the rank correlation test. Ten studies (2 randomized and 8 non-randomized/5,914 patients with EGC or dysplasia) were identified and analyzed. Overall, the Helicobacter pylori eradication group showed a RR of 0.467 (95% CI: 0.362-0.602, P < 0.001) for the development of metachronous gastric cancer after endoscopic resection of EGC. Subgroup analyses showed consistent results. Publication bias was not detected. Helicobacter pylori eradication after endoscopic resection of EGC reduces the occurrence of metachronous gastric cancer.

OBJECTIVE: The pathophysiology of peptic ulcer disease (PUD) in liver cirrhosis (LC) and chronic hepatitis has not been established. The aim of this study was to assess the role of portal hypertension from PUD in patients with LC and chronic hepatitis. MATERIALS AND METHODS: We analyzed the medical records of 455 hepatic vein pressure gradient (HVPG) and esophagogastroduodenoscopy patients who had LC or chronic hepatitis in a single tertiary hospital. The association of PUD with LC and chronic hepatitis was assessed by univariate and multivariate analysis. RESULTS: A total of 72 PUD cases were detected. PUD was associated with LC more than with chronic hepatitis (odds ratio [OR]: 4.13, p = 0.03). In the univariate analysis, taking an ulcerogenic medication was associated with PUD in patients with LC (OR: 4.34, p = 0.04) and smoking was associated with PUD in patients with chronic hepatitis (OR: 3.61, p = 0.04). In the multivariate analysis, taking an ulcerogenic medication was associated with PUD in patients with LC (OR: 2.93, p = 0.04). However, HVPG was not related to PUD in patients with LC or chronic hepatitis. CONCLUSION: According to the present study, patients with LC have a higher risk of PUD than those with chronic hepatitis. The risk factor was taking ulcerogenic medication. However, HVPG reflecting portal hypertension was not associated with PUD in LC or chronic hepatitis (Clinicaltrial number NCT01944878).

BACKGROUND: The aim of this study was to evaluate the association between obesity and infected bile or bacteremia in patients with acute calculous cholecystitis. METHODS: Authors analyzed the medical records of 139 patients who had undergone cholecystectomy for the treatment of acute calculous cholecystitis from January 2007 to June 2013 in a single teaching hospital. Association of body mass index (BMI) with bactibilia and bacteremia was assessed using univariate and multivariate analysis. Clinical findings and biliary infection related data were recorded for the following variables: gender, age, alcohol and smoking history, the results of blood and bile cultures, cholesterolosis, diabetes, hypertension, and duration of the hospital stay. RESULTS: The microbial culture rate of bactibilia and bacteremia were 50.4% and 21.6%, respectively. In the univariate analysis, bacteremia was associated with bactibilia (OR: 4.33, p = 0.002). In the multivariate analysis for the risk factors of bactibilia, BMI and bacteremia were related with bactibilia (OR: 0.59, 95% CI: 0.42-0.84, p = 0.003) (OR: 3.32, 95% CI: 1.22-9, p = 0.02). In the multivariate analysis for the risk factors of bacteremia, BMI, bactibilia and age were related with bacteremia (OR: 0.76, 95% CI: 0.59-0.99, p = 0.04) (OR: 3.46, 95% CI: 1.27-9.45, p = 0.02) (OR: 1.05, 95% CI: 1.01-1.09, p = 0.02). CONCLUSION: In this retrospective study, BMI was inversely correlated with bacteremia or bactibilia, which means obese or overweight patients are less likely to be associated with bacteremia or bactibilia in patients with acute calculous cholecystitis.

BACKGROUND AND AIM: Dietary factors are closely associated with the risk of non-alcoholic fatty liver disease (NAFLD). Asian and Western diets differ in energy-nutrient composition, fatty-acid composition, and main nutritional sources; therefore, the implications would be limited if the Western-oriented study results were applied to Asian patients. We aimed to identify the nutrient and food group intakes of a typical Asian diet and assess their effects on NAFLD risk. METHODS: In total, 348 subjects were recruited from 5 participating hospitals. Information on sociodemographic characteristics and health-related behaviors were obtained through face-to-face interviews. NAFLD was diagnosed by ultrasound. Dietary intakes were assessed with a 24-h recall applying a multiple-pass approach and 4-day food records that included 1 or 2 weekend days. RESULTS: There were no significant differences in health-related behaviors between the cases and controls except for smoking behavior. The cases had elevated triacylglycerol, fasting glucose, and low-density lipoprotein cholesterol levels compared with the controls. In men, after adjusting for variables, low intakes of vitamin C (odds ratio [OR], 4.23), vitamin K (OR, 3.93), folate (OR, 3.37), omega-3 fatty acids (OR, 2.16), and nuts and seeds (OR, 3.66) were associated with a significantly higher risk for developing NAFLD. In women, vitamin K (OR, 2.54) and vegetable (OR, 4.11) intakes showed a significant beneficial effect for lowering NAFLD risk. CONCLUSIONS: Adequate intakes of vitamin C, vitamin K, folate, omega-3 fatty acids, nuts and seeds, and vegetables may help in preventing NAFLD in Korean adults.

INTRODUCTION: Klebsiella pneumoniae-associated liver abscess (KPLA) is often accompanied by extrahepatic complications. We investigated the clinical features and outcomes of patients with and without metastatic infections and compared the 2 groups. METHODS: We retrospectively reviewed the medical records of 161 patients with KPLA who were admitted to 2 tertiary referral hospitals in Korea. RESULTS: In total, 9.9% had a metastatic infection. The most commonly involved distant sites were the eyes (n = 7) and the lungs (n = 6). In multivariate analysis, diabetes mellitus as an underlying disease (odds ratio (OR) 2.30, 95% confidence interval (CI) 1.05-9.51; p = 0.03) and a platelet count < 80,000/mm(3) (OR 11.60, 95% CI 2.53-53.26; p = 0.002) were associated with metastatic infection. Extended-spectrum beta-lactamase (ESBL) production was not observed in K. pneumoniae from patients with metastatic infection, whereas 3.4% of the bacteria in patients without metastatic infection had ESBL production. However, this difference was not statistically significant (p = 0.45). The in-hospital mortality rate was not significantly different (0% vs. 2.8%; p = 0.52). By multivariate analysis, the Acute Physiology and Chronic Health Evaluation II (APACHE II) score was independently associated with mortality among patients with KPLA (OR 1.5, 95% CI 1.12-2.00; p = 0.006). CONCLUSIONS: Clinicians must be aware of potential metastatic infections in patients with KPLA, especially if they have diabetes mellitus and thrombocytopenia. The APACHE II score was predictive of mortality in patients with KPLA.

BACKGROUND/AIMS: Obesity is a chronic inflammatory condition and is strongly linked to raised levels of pro-inflammatory factors and may lead to fatty infiltration of multiple internal organs including the gallbladder and liver, causing organ dysfunction. This study was performed to evaluate the relationship between body mass index (BMI) and acute and chronic cholecystitis, and cholecystitis and cholesterolosis. We investigated the clinical implications of BMI as a predictive factor of cholesterol associated cholecystitis. METHODS: This retrospective study covered the period from January 2007 to December 2011, we included 1,158 patients who had cholecystectomy. We excluded patients with gallbladder cancer, adenomyomatosis, and cholesterolosis without cholecystitis. Finally, we investigated the data of a total of 1,109 patients with cholecystitis. Laboratory test results and clinical data such as age, sex, BMI, height, weight and underlying diseases were examined. We retrospectively investigated acute and chronic cholecysti tis, cholesterol polyps, and other gallbladder diseases such as gallbladder cancer and adenomyomatosis according to the histopathologic findings. RESULTS: There was a significant difference of BMI between patients with cholecystitis with cholesterolosis and without cholesterolosis (P = 0.001). Among patients who had cholecystitis with cholesterolosis, the BMI was 25.2 kg/m2. Among patients with cholecystitis without cholesterolosis, the average BMI was 24.3 kg/m2. Weight, systolic blood pressure, platelet count, glucose, triglyceride, and LDL-cholesterol were different between the groups above (P < 0.05). However, there was no significant difference in BMI between acute and chronic cholecystitis (P = 0.05). CONCLUSIONS: BMI was associated with steatocholecystitis. However, we cannot predict whether cholecystitis is acute or chronic according to the BMI. We suggest that BMI can be used as one of the predictive factors of steatocholecystitis for obese patients.

UNLABELLED: Background/Aims: The aim of this study was to evaluate whether endoscopic retrograde cholangiopancreatography (ERCP) endoscopists can distinguish the type of gastroenteric anastomosis in patients with previous subtotal gastrectomy based on CT findings, particularly in biliary emergencies. METHODOLOGY: A total of 70 abdominal CT scans from patients who had undergone gastrectomy (n = 36, Billroth I; n = 34, Billroth II) were enrolled. The shuffled images were reviewed by 3 ERCP endoscopists blinded to clinical data. The endoscopists were asked to provide the most probable type of anastomosis. The sensitivity, specificity and interobserver agreement were analyzed for identifying Billroth II gastrectomy. RESULTS: The ERCP endoscopists were able to identify the type of anastomosis based on CT findings with a sensitivity, specificity and interobserver agreement of 100%, 97.2%, and 0.98, respectively. The key CT features for distinguishing Billroth II gastrectomy from Billroth I gastrectomy were: i) loss of continuity between the remnant stomach and duodenum; ii) less distended duodenal bulb; iii) the presence of a closed duodenal stump with surgical staples and iv) the presence of continuity between the remnant stomach and the jejunum. CONCLUSIONS: ERCP endoscopists were able to use CT findings to distinguish the type of gastroenteric anastomosis in patients with previous gastrectomy.
