RESUMO
Background/Aims@#Few studies have investigated the long-term outcomes of endoscopic resection for early gastric cancer (EGC) in very elderly patients. The aim of this study was to determine the appropriate treatment strategy and identify the risk factors for mortality in these patients. @*Methods@#Patients with EGC who underwent endoscopic resection from 2006 to 2017 were iden-tified using National Health Insurance Data and divided into three age groups: very elderly (≥85 years), elderly (65 to 84 years), and non-elderly (≤64 years). Their long- and short-term outcomes were compared in the three age groups, and the survival in the groups was compared with that in the control group, matched by age and sex. We also evaluated the risk factors for long- and short-term outcomes. @*Results@#A total of 8,426 patients were included in our study: 118 very elderly, 4,583 elderly, and 3,725 non-elderly. The overall survival and cancer-specific survival rates were significantly lower in the very elderly group than in the elderly and the non-elderly groups. Congestive heart failure was negatively associated with cancer-specific survival. A significantly decreased risk for mortality was observed in all groups (p<0.001). The very elderly group had significantly higher readmission and mortality rates within 3 months of endoscopic resection than the non-elderly and elderly groups. Furthermore, the cerebrovascular disease was associated with mortality within 3 months after endoscopic resection. @*Conclusions@#Endoscopic resection for EGC can be helpful for very elderly patients, and it may play a role in achieving overall survival comparable to that of the control group.
RESUMO
BACKGROUND/AIMS: An association between obesity and erosive esophagitis has been reported, but the effects of sarcopenia and obesity on erosive esophagitis are unknown. This study examined the relationship between obesity, sarcopenia, sarcopenic obesity, and erosive esophagitis in a large population of asymptomatic men and women.METHODS: This study analyzed 32,762 subjects who underwent a comprehensive health check-up, which included upper gastrointestinal endoscopy, from August 2006 to December 2011 by a cross-sectional study. Sarcopenia was defined as a decrease in the appendicular skeletal muscle mass (ASM)/body weight value of two SD or more below the normal means for a younger reference group.RESULTS: The study was carried out on four groups according to obesity and sarcopenic status: normal, obesity, sarcopenic, and sarcopenic obese group. In a multivariable model, the risk of erosive esophagitis was higher in the obese (adjusted OR [aOR] 1.35, 95% CI 1.22–1.49), sarcopenic (aOR 2.12, 95% CI 1.40–3.19), and sarcopenic obese groups (aOR 1.54, 95% CI 1.27–1.87) than in the normal group. The risk of erosive esophagitis was higher in the sarcopenic and sarcopenic obese groups than the obese group; the ORs were 1.63 (95% CI 1.08–2.47) and 1.22 (95% CI 1.01–1.46), respectively. In dose-response analysis, increasing sarcopenia severity showed a positive and graded relationship with the overall, Los Angeles (LA)-B or higher grade, and LA-C erosive esophagitis.CONCLUSIONS: This study suggests that sarcopenia is strongly and progressively associated with erosive esophagitis.
RESUMO
BACKGROUND/AIMS: Helicobacter pylori (H. pylori) infection has been known to cause various extra-gastric diseases, which may be mediated by an increase in systemic inflammation. Thus, we examined the association between H. pylori infection and various markers of systemic inflammation in a large sample of asymptomatic adults. METHODS: Cross-sectional data were obtained from 17,028 adults who completed routine health check-ups. H. pylori infection status was determined using a serum immunoglobulin G test, and systemic inflammation was assessed using the C-reactive protein (CRP) levels, neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR). RESULTS: Multiple linear regression model-adjusted for potential confounders-revealed that H. pylori infection was not associated with CRP levels (coefficient: −0.012, 95% confidence interval [CI]: −0.037, 0.012, p=0.319), NLR (coefficient: 0.055, 95% CI: −0.027, 0.138, p=0.192), or PLR (coefficient: 1.798, 95% CI: −1.979, 5.574, p=0.351). In a multivariable logistic regression model, H. pylori infection was not associated with the risk of CRP levels being elevated to ≥0.1 mg/dL (odds ratio: 0.96, 95% CI: 0.81, 1.08) or ≥0.3 mg/dL (odds ratio: 1.02, 95% CI: 0.84, 1.19). In the multivariable model, CRP levels elevated to ≥0.1 mg/dL were significantly associated with body mass index, current smoking status, hypertension, and diabetes mellitus. Regular exercise and high-density lipoprotein cholesterol were factors that minimized the elevation of CRP levels. CONCLUSIONS: Chronic infection with H. pylori was not associated with various inflammatory markers. Further investigation is needed to clarify the interaction between H. pylori infection, systemic inflammation, and extra-gastric disease.

BACKGROUND/AIMS: Levofloxacin resistance is increasing rapidly, and widely limits its application in Helicobacter pylori eradication. This study aimed to evaluate the efficacy of a clarithromycin- versus gemifloxacin-containing triple therapy regimen in first-line eradication of H. pylori infection. MATERIALS AND METHODS: This was an open-label, prospective, non-randomized two-armed pilot study in which treatment-naïve subjects with active H. pylori infection received a seven-day triple therapy with rabeprazole 20 mg bid (twice daily), gemifloxacin 320 mg qd (once daily), and amoxicillin 500 mg bid (n=70) or seven-day triple therapy with rabeprazole 20 mg bid (twice daily), clarithromycin 500 mg bid (twice daily), and amoxicillin 500 mg bid (n=83). H. pylori infection status was checked in all patients at enrollment and at least 8 weeks after the end of therapy by the urea breath test. RESULTS: Intention-to-treat eradication rates were 71.1% and 74.3% for clarithromycin-containing triple therapy and gemifloxacin- containing triple therapy, respectively (P=0.398). The corresponding per-protocol eradication rates were 76.6% and 76.1% (P=0.624). The gemifloxacin-containing triple therapy was associated with a lower incidence of adverse events (2.9% vs. 18.5%, P=0.003). CONCLUSIONS: Although the seven-day gemifloxacin-containing triple therapy regimen showed a more favorable safety profile, there was no significant difference in eradication rates between the gemifloxacin-containing and clarithromycin-containing triple regimens, and both regimens had eradication rates slightly lower than acceptable efficacy for the Korean population. Therefore, the gemifloxacin-containing regimen might be useful as an alternative regimen for patients showing severe side effects of clarithromycin due to poor tolerance. Further studies on the efficacy of gemifloxacin in the Korean population are warranted.

BACKGROUND/AIMS: Although it is generally known that the risk for all types of cancer increases with adult height, combined and for several common site-specific cancers (including colon and rectal), evidence is limited for adenomas, which are precursors to colorectal cancer. We evaluated the association between height and risk of colorectal adenoma at various stages of the adenoma-carcinoma pathway. METHODS: We conducted a retrospective study using data from patients who had undergone a complete colonoscopy as part of a health examination at the Health Promotion Center of Samsung Medical Center between October 13, 2009 and December 31, 2011. A total of 1,347 male subjects were included in our study. Multivariate logistic regression analysis was used to evaluate the association between height and colorectal adenoma. RESULTS: Each 5-cm increase in height was associated with 1.6% and 5.3% higher risks of advanced colorectal adenoma and high-risk colorectal adenoma, respectively, but associations were not significant after adjusting for age, body mass index, metabolic syndrome, alcohol intake, smoking, family history of colorectal cancer, and regular aspirin use (p = 0.840 and p = 0.472, respectively). CONCLUSIONS: No clear association was found between colorectal adenoma risk and height. Unlike other site-specific tumors reported to have a consistent relationship with height, the association between colorectal tumor and height remains controversial.

Neostigmine can successfully decompress patients with acute colonic pseudo-obstruction (ACPO) who are unresponsive to conservative therapy. However, neostigmine is contraindicated in renal failure, so it is underused in ACPO patients with renal failure who would be otherwise appropriate candidates. We described the first successfully treated case of acute kidney injury (AKI) with neostigmine in a patient with ACPO. A 72-year-old man who underwent a coronary artery bypass graft surgery 11 days prior presented to the emergency room with abdominal distension, peripheral edema, and dyspnea on exertion. Plain abdominal radiographs and abdomen computed tomography scan showed diffuse colonic dilatation without obstruction. Serum creatinine level was increased five-fold over baseline. We diagnosed the patient as ACPO with AKI. With conservative treatment, renal function failed to improve because the ACPO was not corrected. Administration of neostigmine rapidly resolved ACPO and renal function, avoiding more invasive procedures such as colonoscopic decompression and hemodialysis. Neostigmine appears to be an effective and safe treatment option for ACPO patients with renal failure. Prospective large-scale studies should be carried out to determine the safety and efficacy of neostigmine in ACPO patients with renal failure.

BACKGROUND/AIMS: The aim of this study was to compare the clinical effects of preoperative and postoperative dexamethasone on pain after endoscopic submucosal dissection (ESD) for early gastric neoplasm. METHODS: Forty patients with early gastric neoplasm who were scheduled for ESD were randomized into two groups according to the timing of steroid administration: preoperative ("pre", n=20) and postoperative ("post", n=20) steroid administration. The pre group received 0.15 mg/kg dexamethasone before ESD and placebo after, and the post group received pre-ESD placebo and post-ESD dexamethasone. The present pain intensity (PPI) index and the short-form McGill pain (SF-MP) questionnaire were evaluated. RESULTS: The primary outcome was PPI score at 6 hours after ESD. There was a greater reduction in 6-hour PPI in the pre group than in the post group (2.1±0.8 vs 3.0±1.1, respectively; p=0.006). The immediate PPI was also significantly lower in the pre group than in the post group (1.6±0.6 vs 2.9±0.6, respectively; p<0.001), and the total SF-MP scores were significantly lower in the pre group than in the post group both immediately and at 6 hours after the operation. CONCLUSIONS: Preoperative administration of dexamethasone may produce a superior analgesic effect in patients who undergo ESD compared with the postoperative administration of dexamethasone.

BACKGROUND/AIMS: Hepatitis-B-related acute-on-chronic liver failure has a poor prognosis. However, the advent of potent oral antiviral agents means that some patients can now recover with medical treatment. We aimed to identify the prognostic factors for hepatitis-B-related acute-on-chronic liver failure including the initial as well as the dynamically changing clinical parameters during admission. METHODS: Sixty-seven patients were retrospectively enrolled from 2003 to 2012 at Samsung Medical Center. The patients were classified into three categories: Recovery group (n=23), Liver transplantation group (n=28), and Death group (n=16). The Liver transplantation and Death groups were combined into an Unfavorable prognosis group. We analyzed the prognostic factors including the Model for End-Stage Liver Disease (MELD) scores determined at 3-day intervals. RESULTS: A multivariable analysis showed that the unfavorable prognostic factors were a high initial MELD score (> or =28) (odds ratio [OR] =6.64, p=0.015), moderate-to-severe ascites at admission (OR=6.71, P=0.012), and the aggravation of hepatic encephalopathy during hospitalization (> or =grade III) (OR=15.41, P=0.013). Compared with the baseline level, significant reductions in the MELD scores were observed on the 7th day after admission in the Recovery group (P=0.016). CONCLUSIONS: Dynamic changes in clinical parameters during admission are useful prognostic factors for hepatitis-B-related acute-on-chronic liver failure.

Behcet's disease is an inflammatory disorder characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. A few cases of hematologic disease in patients with Behcet's disease have been reported in the literature. However, acute precursor T cell lymphoblastic leukemia has never been described in association with Behcet's disease. We recently encountered a case of acute precursor T cell lymphoblastic leukemia in a 62-year-old man with a prior diagnosis of Behcet's disease. The patient presented with febrile neutropenia and his bone marrow biopsy revealed acute precursor T cell lymphoblastic leukemia. He was scheduled to undergo therapeutic chemotherapy, but unfortunately he died from pneumonia prior to treatment.

Hypereosinophilia is often associated with eosinphilic infiltration of tissue, which can lead to severe and irreversible organ damage. One of the most characteristic and critical complications is development of thrombosis in cardiac ventricles, and occasionally in deep veins. We report a rare case of hypereosinophilia, with peripheral vascular thrombosis, caused by Toxocara canis infection.

We presented two interesting cases of gastrocolocutaneous fistula that occurred after percutaneous endoscopic gastrostomy (PEG) tube placement, and its management. This fistula is a rare complication that occurs after PEG insertion, which is an epithelial connection between mucosa of the stomach, colon, and skin. The management of the fistula is controversial, ranging from conservative to surgical intervention. Endoscopists should be aware of the possibility of gastrocolocutaneous fistula after PEG insertion, and should evaluate the risk factors that may contribute to the development of gastrocolocutaneous fistula before the procedure. We reviewed complications of gastrostomy tube insertion, symptoms of gastrocolocutaneous fistula, and its risk factors.

Pseudomyxoma peritonei is a rare clinical condition that causes the accumulation of mucinous ascites, which gradually results in the compression of intra-abdominal organs. Most published reports of pseudomyxoma peritonei concern the mass effect of the resulting ascites, which presents as abdominal pain or intestinal ileus in severe cases. However, few reports of renal complications of the disease have been published. Here, we present a case of oliguric acute kidney injury caused by external compression by pseudomyxoma peritonei. After decompression with external drainage, the patient's renal function rapidly improved.

Primary small intestinal lymphoma is relatively uncommon. Small bowel tumors are difficult to diagnose, because they are usually asymptomatic in the initial phase, and they are not easily detected by traditional methods of investigating the small intestine. This case shows a successfully detected and treated gastrointestinal bleeding from rare ileal mucosa-associated lymphoid tissue lymphoma, using double balloon endoscopy.

In several previously reported studies, metabolic syndrome (MS) was found to be associated with colorectal adenomas. While the incidence of colorectal adenoma is growing in Korean population, there are only few studies that examined the association between MS and colorectal adenoma in Korea. The aim of this study was to investigate relationships between prevalence of colorectal adenoma and MS components. We conducted a cross sectional study using data from individuals who had undergone complete colonoscopy for health examinations at the Health Promotion Center of Korea University Medical Center from July 1, 2004 to July 31, 2010. A total of 7481 subjects (4459 males and 3022 females) were included; 1733 subjects with pathologically proven adenoma were assigned to the case group, and other 5748 subjects were assigned to the non-case group. All the participants underwent colonoscopy and received blood biochemical tests (fasting blood sugar [FBS], insulin, lipid profile, hemoglobin, blood urea nitrogen [BUN], creatinine). Univariate analysis showed that the prevalence of colorectal adenoma was higher in individuals with higher blood pressure, body mass index (BMI), total cholesterol (TC), triglyceride (TG), FBS and lower high-density lipoprotein cholesterols (HDL-C) levels, compared to those with low levels. Multiple logistic regression analysis revealed that high levels of BMI (OR 1.17, 95% CI 1.01-1.34, P trend = 0.01), TG (OR 1.27, 95% CI 1.07-1.51, P trend = 0.006), and FBS (OR 1.19 95% CI 1.01-1.40, P trend = 0.05) were significantly associated with prevalence of colorectal adenoma. Subjects with high levels of BMI, TG and FBS have increased prevalence of developing colorectal adenoma in Korea.
