RESUMO
Background/Aims@#There are no data regarding the association between sarcopenic obesity status and nonalcoholic fatty liver disease (NAFLD) and NAFLD-associated liver fibrosis. Therefore, we aimed to investigate the relationship between sarcopenic obesity status (sarcopenia only, obesity only, and sarcopenic obesity) and NAFLD and liver fibrosis in Korean adults. @*Methods@#In total, 2,191 subjects completed a health checkup program, including abdominal ultrasonography and FibroScan. Subjects were classified into the following four categories: optimal body composition (nonobese and nonsarcopenic), sarcopenia only (nonobese), obesity only (nonsarcopenic), and sarcopenic obesity. Sarcopenic obesity was stratified by the skeletal muscle mass index and body fat using bioelectrical impedance analysis. NAFLD was diagnosed by ultrasonography, and liver fibrosis was assessed using transient elastography in subjects with NAFLD. @*Results@#The prevalence of NAFLD and liver fibrosis significantly increased according to the sarcopenic obesity status. In the logistic regression analysis, after adjusting for multiple risk factors, the odds ratio (OR) for the risk of NAFLD was largest in the sarcopenic obesity group (OR, 3.68; 95% confidence interval [CI], 2.94 to 4.60), followed by the obesity only (OR, 2.25; 95% CI, 1.67 to 3.03) and sarcopenia only (OR, 1.92; 95% CI, 1.30 to 2.84) groups, when compared with the optimal group. Additionally, liver fibrosis was independently associated with sarcopenic obesity status (OR 4.69, 95% CI 1.95 to 11.29; OR 4.17, 95% CI 1.56 to 11.17; OR 3.80, 95% CI 0.86 to 16.75, respectively). @*Conclusions@#These results demonstrated that sarcopenic obesity was independently associated with NAFLD and liver fibrosis and increased the risk of NAFLD and liver fibrosis more than obesity or sarcopenia alone.
RESUMO
Background/Aims@#To investigate the risk of metabolic syndrome and fatty liver diseases in gastric cancer survivors compared to non-cancer subjects. @*Methods@#The data from the health screening registry of the Gangnam Severance Hospital from 2014–2019 was used. Ninety-one gastric cancer survivors and a propensity-score-matching 445 non-cancer subjects were analyzed. Gastric cancer survivors were divided into those with surgical treatment (OpGC, n=66) and non-surgical treatment (non-OpGC, n=25). Metabolic syndrome, fatty liver by ultrasonography, and metabolic dysfunction-associated fatty liver disease (MAFLD) were assessed. @*Results@#Metabolic syndrome was in 15.4% of gastric cancer survivors (OpGC; 13.6%, non-OpGC; 20.0%). Fatty liver by ultrasonography was in 35.2% in gastric cancer survivors (OpGC; 30.3%, non-OpGC: 48.0%). MAFLD was in 27.5% of gastric cancer survivor (OpGC; 21.2%, non-OpGC; 44.0%). After adjusting for age, sex, smoking, and alcohol, the risk of metabolic syndrome was lower in OpGC than in non-cancer subjects (OR, 0.372; 95% CI, 0.176-0.786, p=0.010). After adjusting, OpGC showed lower risks of fatty liver by ultrasonography (OR, 0.545; 95% CI, 0.306-0.970, p=0.039) and MAFLD (OR, 0.375; 95% CI, 0.197-0.711, p=0.003) than did non-cancer subjects. There were no significant differences in the risks of metabolic syndrome and fatty liver diseases between non-OpGC and non-cancer subjects. @*Conclusions@#OpGC showed lower risks of metabolic syndrome, fatty liver by ultrasonography, and MAFLD than non-cancer subjects, but there were no significant differences in the risks between non-OpGC and non-cancer subjects. Further studies on metabolic syndrome and fatty liver diseases in gastric cancer survivors are warranted.
RESUMO
BACKGROUND: Recently, the triglyceride glucose (TyG) index has been considered a surrogate marker of insulin resistance which is a well-known pathogenic factor in nonalcoholic fatty liver disease (NAFLD). However, few studies have investigated the relationship between the TyG index and NAFLD. Thus, we investigated the relationship between the TyG index and NAFLD and the effectiveness of the TyG index compared with the homeostasis model assessment of insulin resistance (HOMA-IR) in identifying NAFLD in Korean adults. METHODS: Participants of 4,986 who underwent ultrasonography in a health promotion center were enrolled. The TyG index was calculated as ln [fasting triglycerides (mg/dL)×fasting glucose (mg/dL)/2], and HOMA-IR was estimated. NAFLD was diagnosed by ultrasonography. RESULTS: Significant differences were observed in metabolic parameters among the quartiles of the TyG index. The prevalence of NAFLD significantly increased with increment in the TyG index. After adjusting for multiple risk factors, a logistic regression analysis was performed. When the highest and lowest quartiles of the TyG index and HOMA-IR were compared, the odds ratios for the prevalence of NAFLD were 2.94 and 1.93 (95% confidence interval, 2.32 to 3.72 and 1.43 to 2.61; both P for trend <0.01), respectively. According to the receiver operating characteristic analysis, the TyG index was superior to HOMA-IR in predicting NAFLD. CONCLUSION: The TyG index and prevalence of NAFLD were significantly related and the TyG index was superior to HOMA-IR in predicting NAFLD in Korean adults.

BACKGROUND: Korean Americans constitute the fifth largest subgroup in the Asian American population. Despite their increasing population, research and guidelines regarding their health status assessment and disease screening are lacking. This study aimed to compare the prevalence of diseases in Korean Americans and native Koreans to determine the risk factors and guidelines for disease screening. METHODS: Patients who visited the Gangnam Severance Hospital from February 2010 to May 2015 for a health checkup were enrolled in this study. Baseline characteristics, laboratory data, and the organs (stomach, colon, thyroid, brain, prostate, lung, liver, kidney, pancreas, adrenal gland, and heart) of patients were examined. Data regarding patients' dietary patterns were also obtained. Overall, 1,514 Korean Americans (group 1) and 1,514 native Koreans (group 2) were enrolled. RESULTS: The following diseases were more prevalent in group 1 than in group 2: reflux esophagitis (12.9% vs. 10%), gastric ulcer (3.0% vs. 5.5%), colorectal polyp (37.7% vs. 28.7%), hemorrhoids (32.2% vs. 29.9%), and benign prostatic hyperplasia (30.2% vs. 14.3%). Although not statistically significant, coronary artery disease has a high prevalence rate of >20% in both groups. Dietary patterns were not significant between the two groups. CONCLUSION: This study showed that the prevalence of several diseases in Korean Americans differed from that observed in native Koreans. Therefore, a foundation for setting up new guidelines for disease screening among Korean Americans is established.

BACKGROUND/AIMS: Hepatic innervation in liver diseases is not fully understood. We here evaluated S100B expression as a marker of hepatic nerves in patients with various chronic liver diseases, topographically and semi-quantitatively. METHODS: Liver specimens were obtained from 70 subjects (three controls, and 32 chronic hepatitis B, 14 chronic hepatitis C, 14 liver cirrhosis, and seven hepatocellular carcinoma patients). The hepatic nerve density was calculated based on immunohistochemical staining of S100B protein in the portal tracts and hepatic lobules. S100B mRNA levels were semi-quantitatively assessed as the S100B/glyceraldehyde 3-phosphate dehydrogenase (GAPDH) mRNA ratio. RESULTS: The densities of the hepatic nerves in portal tracts of chronic liver diseases were not significantly different from those of normal controls but the hepatic nerve densities in lobular areas of liver cirrhosis were significantly decreased (p = 0.025). Compared to the control, the S100B/GAPDH mRNA ratio was significantly decreased in chronic liver diseases (p = 0.006) and most decreased in chronic hepatitis C patients (p = 0.023). In chronic liver diseases, The S100B/GAPDH mRNA ratio tended to decrease as the fibrosis score > 0 (p = 0.453) but the overall correlation between the S100B/GAPDH mRNA ratio and fibrosis score was not statistically significant (r = 0.061, p = 0.657). CONCLUSIONS: Hepatic innervation is decreased in cirrhotic regenerating nodules compared to the control group and seems to decrease in early stages of fibrosis progression. Further studies are needed to clarify the association between changes of hepatic innervation and chronic liver disease progression.

BACKGROUND/AIMS: We aimed to estimate the cumulative incidence of advanced colonic neoplasia and analyze the risk factors for advanced colonic neoplasia according to risk components and adenoma location at index colonoscopy. METHODS: We reviewed 1,974 subjects who underwent a follow-up colonoscopy after a complete screening colonoscopy and the removal of all polyps. We estimated the cumulative incidence of a subsequent advanced neoplasia according to risk groups (normal, low-risk, and high-risk). Risk factors were analyzed by risk components (≥3 adenomas, adenoma ≥1 cm, and villous-type adenoma) and adenoma location. RESULTS: Overall, 111 advanced neoplasias (5.6%) were newly diagnosed at the follow-up colonoscopy. The 3-year cumulative incidences of advanced neoplasia were 0.8%, 3.1%, and 10.2% in the normal, low-risk, and high-risk groups, respectively (p<0.0001), and the 5-year cumulative incidences were 2.2%, 8.6%, and 20.2%, respectively (p<0.0001). Age ≥60 years (hazard ratio [HR], 1.78; 95% confidence interval [CI], 1.21 to 2.63), right-sided colonic adenoma (HR, 1.74; 95% CI, 1.13 to 2.66), ≥3 adenomas (HR, 2.00; 95% CI, 1.22 to 3.28), and adenomas ≥1 cm in size (HR, 2.03; 95% CI, 1.20 to 3.44) in the index colonoscopy were independent risk factors for subsequent development of advanced neoplasia. CONCLUSIONS: Right-sided colonic adenoma, ≥3 adenomas, adenomas ≥1 cm, and age ≥60 years at the index colonoscopy were significant risk factors for advanced neoplasia following a complete screening colonoscopy and removal of all polyps.

OBJECTIVES: The purpose of this study was to compare the safety and efficacy of midazolam sedated Endoscopic retrograde cholangiopancreatography (ERCP) with unsedated ERCP in patients 70 years of ages and older. METHODS: Seventy elderly patients 70 years of age or older who underwent ERCP were divided into two groups: midazolam sedated group (n=43) and unsedated group (n=27). Procedure time, success rate, complications related with ERCP procedure, satisfaction score were analyzed between two groups. RESULTS: Mean procedure time was 20.6 minutes for sedated group and 21.0 minutes for unsedated group (P=0.88). Success rate was 87.5% for sedated group and 100% for unsedated group (P=0.07). Incidence of complications from ERCP procedure showed no significant differences between the sedated and unsedated groups (P=0.10). There was no mortality in both groups related to the sedation or post-ERCP complication. Compared to the unsedated procedure, the sedated ERCP procedure was associated with higher patient satisfaction (P<0.001) and better repeat compliance (P=0.004). CONCLUSION: There was no significant difference in success rate and complications at sedated and unsedated ERCP in patients 70 years of age and older. Unsedated ERCP showed 66.6% satisfaction score compared to sedated ERCP.

Obstructive jaundice caused by tuberculous lymphadenitis is a rare manifestation of tuberculosis (TB), with 15 cases having been reported in Korea. We experienced a case of obstructive jaundice caused by pericholedochal tuberculous lymphadenitis in a 30-year-old man. The patient's initial serum total bilirubin level was 21.1 mg/dL. Abdominal computed tomography revealed narrowing of the bile duct by a conglomerated soft-tissue mass involving the main portal vein. Abrupt obstruction of the common bile duct was observed on cholangiography. Pathologic analysis of a ultrasonography-guided biopsy sample revealed chronic granulomatous inflammation, and an endoscopic examination revealed esophageal varices and active duodenal ulceration, the pathology of which was chronic noncaseating granulomatous inflammation. Hepaticojejunostomy was performed and pathologic analysis of the conglomerated soft-tissue mass revealed chronic granulomatous inflammation with caseation of the lymph nodes. Tuberculous lymphadenitis should be considered in patients presenting with obstructive jaundice in an endemic area.

BACKGROUND/AIMS: In South Korea, health check-ups are readily accessible to the public. We aimed to compare the prevalence of upper gastrointestinal (GI) and lower GI diseases in Korean Americans and native Koreans to determine differences and risk factors. METHODS: In total, 1,942 subjects who visited Gangnam Severance Hospital from July 2008 to November 2010 for a health check-up were enrolled. Basic characteristics and laboratory data for the subjects were collected. Esophagogastroduodenoscopy and colonoscopy were performed. In total, 940 Korean Americans (group 1) and 1,002 native Koreans (group 2) were enrolled. RESULTS: The overall prevalence of GI diseases for each group (group 1 vs group 2) were as follows: reflux esophagitis (RE) (9.65% vs 7.9%), gastric ulcer (2.8% vs 3.4%), duodenal ulcer (2.3% vs 3.6%), gastric cancer (0.4% vs 0.3%), colorectal polyp (35.9% vs 35.6%), colorectal cancer (0.5% vs 0.5%), and hemorrhoids (29.4% vs 21.3%). The prevalence of hemorrhoids was significantly higher in group 1 than in group 2 (p=0.001). In the multivariable analysis of group 1, male sex, age over 50 years, hypercholesterolemia and hypertriglyceridemia predicted colorectal polyps. Male sex and high fasting glucose levels were associated with RE. CONCLUSIONS: Our study showed that the prevalence of GI diseases (except hemorrhoids) in Korean Americans was similar to that observed in native Koreans. Therefore, the Korean guidelines for upper and lower screening endoscopy may be applicable to Korean Americans.

BACKGROUND/AIMS: Current international guidelines recommend colorectal cancer screening for average-risk people over 50 years of age. Accordingly, we aimed to estimate the prevalence of colorectal neoplasms in all age groups and evaluate associated risk factors. METHODS: Data of 14,932 subjects who underwent colonoscopy from July 2006 to January 2012 at Health Promotion Center, Gangnam Severance Hospital (Seoul, Korea) as part of a health check-up were reviewed retrospectively. RESULTS: The overall prevalence of colorectal neoplasms and adenoma were 34.6% and 25.3%, respectively. Colorectal adenoma was found in 3.2%, 13.0%, 21.7%, 33.8%, 44.0%, 50.5%, and 54.2% of subjects under 30 years, 30-39 years, 40-49 years, 50-59 years, 60-69 years, 70-79 years, and over 80 years of age (trend p<0.0001). Independent predictors of colorectal adenoma included male gender (OR 2.38, 95% CI 2.084-2.718), positive occult blood (2.266, 1.761-2.917), positive serology of Helicobacter pylori (1.253, 1.114-1.409) and hypertriglyceremia (1.267, 1.065-1.508). Compared to the 30-39 years of age reference group, the ORs for each age group were 0.195 (under 30 years), 1.634 (40-49 years), 2.954 (50-59 years), 5.159 (60-69 years), 5.640 (70-79 years), 11.020 (over 80 years), while the 95% CIs were 0.071-0.536 (under 30 years), 1.340-1.992 (40-49 years), 2.421-3.604 (50-59 years), 4.109-6.476 (60-69 years), 3.822-8.322 (70-79 years), and 2.809-42.234 (over 80 years). CONCLUSIONS: Colorectal adenoma prevalence increased proportionally with age. Only subjects under the age of 30 years had a definitely lower prevalence of colorectal adenoma. Male gender, positive occult blood, positive serology of H. pylori, and hypertriglyceremia were associated risk factors of colorectal adenoma.

BACKROUND/AIMS: Bismuth-based quadruple therapy for second-line eradication treatment achieves the eradication rate ranging from 70% to 81% due to antimicrobial resistance and poor compliance. The aim of this study was to compare the eradication rate of levofloxacin-based triple therapy with that of bismuth-based quadruple therapy in second-line Helicobacter pylori (H. pylori) eradication therapy. METHODS: Seventy-six outpatients with persistent H. pylori infection after first-line triple therapy were enrolled in this prospective randomized trial. The subjects were randomized to receive levofloxacin 300 mg, amoxicillin 1 g, and pantoprazole 20 mg, given twice daily for 7 days (LAP group), or metronidazole 500 mg twice, tetracycline 500 mg four times, and pantoprazole 20 mg twice, bismuth subcitrate 600 mg twice daily for 7 days (MTPB group). Eradication was confirmed with 13C-urea breath test or rapid urease test 4 weeks after the cessation of therapy. RESULTS: Among Seventy-six patients initially included, eleven were lost during follow-up. The eradication rates, expressed as intention to treat (ITT) and per protocol (PP) analyses, were 51.6% and 53.3% in the LAP group, and 48.9% and 62.9% in the MTPB group, respectively. There was no significant difference in H. pylori eradication rates between the two groups (p=0.815 by ITT, p=0.437 by PP). LAP regimen was better tolerated than MTPB regimen with lower incidence of side effects (10.0% versus 31.4%, p=0.03). CONCLUSIONS: H. pylori eradication rates of levofloxacin-based triple therapy and bismuth-based quadruple therapy were not significantly different in second-line H. pylori eradication therapy, and low incidence of side effects was observed in levofloxacin-based triple therapy.

Human immunodeficiency virus (HIV) infection is a risk factor for developing non-Hodgkin's lymphoma. Most acquired immune deficiency syndrome (AIDS)-related lymphomas are high-grade B cell non-Hodgkin's lymphomas. The use of highly active antiretroviral therapy has reduced the incidence of AIDS-related lymphoma. There have been 7 reports of AIDS-related extra-nodal lymphoma in Korea. We report a case of AIDS-related lymphoma detected by MiroCam(R) capsule endoscopy.

Bezoars are accumulations of foreign materials and foods in the gastrointestinal tract and can be the cause of small bowel obstruction. A bezoar usually begins as a gastric phytobezoar that migrates to the small bowel in patients who have undergone gastric surgery and have delayed gastric emptying. We report a case of diagnosed small bowel obstruction due to the presence of a persimmon phytobezoar (diospyrobezoar) in a patient with a history of gastric surgery. Abdomen-pelvis computed tomography demonstrated the presence of an air-containing localized lesion (5x3.5 cm), a suspicious bezoar in the jejunum. The gastroduodendoscopy failed to reach to the lesion but diospyrobezoars were found in the proximal jejunum at 120 cm from the upper incisors using a colonoscope inserted using the oral approach. Most of the bezoars were fragmented by a tripod and were removed with a snare. The patient was discharged after symptomatic improvement without surgery. We report this case with a review of the relevant literature.

Oral sodium phosphate is known to be safe and it is widely used as a colon cleansing agent for colonoscopy. Yet several complicated cases with the development of electrolyte imbalance have been reported. We report here on 2 interesting cases: after administration of oral sodium phosphate, one patient presented with hyponatremia (Na, 122 mEq/L) with seizure and the other patient presented with hyponatremia (Na, 120 mEq/L) with a confused mentality. Brain imaging and electroencephalography showed no evidence of other causes for the seizure and mental change. We report here on two cases of hyponatremia with neurologic side effects, and this was all caused by oral sodium phosphate. We also include a review of the relevant literature.

Scrub typhus, an acute febrile illness caused by Orientia tsutsugamushi-induced vasculitis, is common in Korea, Asia and Pacific Islands. Endoscopic mucosal lesions or mucosal damages have rarely been reported in Scrub typhus. However, four cases of upper gastrointestinal bleeding, controlled by hemoclipping, in Tsutsugamushi-infected patients have been reported in Korea; although, no case of lower gastrointestinal bleeding in Scrub typhus has been reported. We experienced massive hematochezia in a 77-year-old female patient with Scrub typhus. Special studies, including upper gastroduodenoscopy, colonoscopy, abdominal CT scan, and SMA angiography were performed, but the focus of the bleeding could not be found. An RBC scan showed suspicious small bowel bleeding, but a capsule endoscopy could not reveal the focus of the bleeding focus; however, a colonoscopy showed active bleeding at the terminal ileum, with multiple ileal ulcerations. After conservative therapy, the patient's condition was stable and the hematochezia disappeared.

Gastrointestinal bleeding from small bowel lesions is uncommon but it is the most common cause of obscure gastrointestinal bleeding that can go undiagnosed using traditional upper endoscopy and colonoscopy. Recently, various new methods, including wireless capsule endoscopy and double-balloon enteroscopy have been used to detect and manage small bowel lesions. A 51-year-old man was admitted with hematochezia. The source of bleeding could not be identified using conventional upper endoscopy and colonoscopy. Wireless capsule endoscopy revealed a mass-like lesion with active blood spurting in the proximal jejunum. Finally, a tumor with central ulceration was detected at the proximal jejunum using a clean colonoscope through the oral approach. This lesion was surgically resected, and the histology findings were consistent with a gastrointestinal stromal tumor. We report a case of gastrointestinal bleeding from a proximal jejunal GIST diagnosed by clean colonoscopy through the oral approach with a review of the relevant literature.

Colonic diverticulosis is small outpouching from the lumen of the colon, and this caused by mucosal herniation. Most patients are asymptomatic, but 5~15% of those affected manifest diverticular bleeding. Because most of them stop bleeding spontaneously, the source of the bleeding can not be found by colonoscopy in 15% of these cases. We report here on a case of sigmoid diverticular bleeding that detected by capsule endoscopy in a 68-year old woman who presented with acute obscure gastrointestinal bleeding.

Adenoid cystic carcinoma (ACC) is common in the salivary glands but rare in the esophagus. Routine esophagogastroscopy performed in a 54-year-old woman as part of a medical check-up revealed a submucosal tumor (1.5x1.0 cm) at the mid-esophagus. Endoscopic ultrasonography revealed a lesion with mixed echogenicity in the submucosal layer. The submucosal mass was removed by incisional endoscopic enucleation, and pathological analysis revealed epithelial cells with small hyperchromatic angular nuclei in tubular and cribriform patterns. The lesion was pathologically confirmed as an ACC of the esophagus.

Collagenous colitis is recognized as one of the causes of chronic diarrhea accompanied with autoimmune diseases. It is a disease associated with chronic watery diarrhea and typical histologic findings of a thick subepithelial collagenous deposit on biopsy. We experienced a 75-year-old man patient with chronic watery diarrhea and mild abdominal pain for 7 years. Physical examination, laboratory and radiologic studies were unremarkable except hypokalemia. Colonoscopy disclosed mucosal atrophy, loss of submucosal vessel and altered vascularity of terminal ileum, ascending colon. Colonoscopic biopsy revealed homogenous hyaline layered collagen deposition beneath the surface epithelium and Masson's trichrome stain showed collagen deposition. We report the case of collagenous colitis with a review of literature.

BACKGROUND/AIMS: FDG-PET is widely used for the evaluation of cancer patients. FDG-PET is usually employed for a staging of colorectal cancer and for the early detection of postoperative recurrence of cancer. Areas of focal uptake that suggest colonic lesions, including benign adenoma, may be seen on an FDG-PET image. This study evaluated the characteristics of colonic adenoma as detected by FDG-PET. METHODS: 60 subjects (M/F: 30:30, mean age: 55+/-11) who underwent both PET study and colonoscopy were enrolled and their data were retrospectively analyzed. RESULTS: A total of 50 lesions of colonic adenoma (3~35 mm) were found in 17 subjects by colonoscopy. Compared with the colonoscopic findings, FDG- PET had a positive predictive value of 52.9% and a negative predictable value of 81.4%. The positive rate increased with the size of the colonic adenoma (15 mm, 100.0%; > or =10 mm, 82.4%; <5 mm, 0.0%) and with the protruded type of polyp (sessile, 25.0%; subpedunculated, 47.7%; pedunculated, 90.9%). CONCLUSIONS: FDG-PET positive colonic lesions should raise a concern for not only possible malignancy, but also for the large sized or malignant transforming colonic adenoma.
