RESUMEN

BACKGROUND/AIMS: There has been major progress in our understanding of the irritable bowel syndrome (IBS), and novel treatment classes have emerged. The Rome IV guidelines were published in 2016 and together with the growing body of Asian data on IBS, we felt it is timely to update the Asian IBS Consensus. METHODS: Key opinion leaders from Asian countries were organized into 4 teams to review 4 themes: symptoms and epidemiology, pathophysiology, diagnosis and investigations, and lifestyle modifications and treatments. The consensus development process was carried out by using a modified Delphi method. RESULTS: Thirty-seven statements were developed. Asian data substantiate the current global viewpoint that IBS is a disorder of gut-brain interaction. Socio-cultural and environmental factors in Asia appear to influence the greater overlap between IBS and upper gastrointestinal symptoms. New classes of treatments comprising low fermentable oligo-, di-, monosacharides, and polyols diet, probiotics, non-absorbable antibiotics, and secretagogues have good evidence base for their efficacy. CONCLUSIONS: Our consensus is that all patients with functional gastrointestinal disorders should be evaluated comprehensively with a view to holistic management. Physicians should be encouraged to take a positive attitude to the treatment outcomes for IBS patients.

RESUMEN

BACKGROUND/AIMS: In addition to the globally endorsed Barcelona Clinic Liver Cancer (BCLC) staging system, other algorithms or staging systems have been developed, including the Hong Kong Liver Cancer (HKLC) staging system. This study aimed to validate the HKLC staging system relative to the BCLC staging system for predicting survival for hepatocellular carcinoma (HCC) patients in Korea. METHODS: From 2004 to 2013, 2,571 patients newly diagnosed with HCC were consecutively enrolled at three Korea University medical centers. RESULTS: Both staging systems differentiated survival well (p < 0.001). However, 1-year and 3-year survival were predicted better using the HKLC system than the BCLC system (area under the receiver operating characteristic curve: 0.869 vs 0.856 for 1 year, p=0.002; 0.841 vs 0.827 for 3 years, p=0.010). In hypothetical survival curves, the HKLC system exhibited better median overall survival than the BCLC system (33.1 months vs 19.2 months). In evaluations of prognosis according to either BCLC or HKLC treatment guidelines, risk of death was reduced in the group following only HKLC guidelines compared with the group following only BCLC guidelines (hazard ratio, 0.601; 95% confidence interval, 0.443 to 0.816; p=0.001). CONCLUSIONS: Although both staging systems predicted and discriminated HCC prognoses well, the HKLC system showed more encouraging survival benefits than the BCLC system.

RESUMEN

BACKGROUND/AIMS: Several specific foods are known to precipitate gastroesophageal reflux disease (GERD) symptoms and GERD patients are usually advised to avoid such foods. However, foods consumed daily are quite variable according to regions, cultures, etc. This study was done to elucidate the food items which induce typical GERD symptoms in Korean patients. METHODS: One hundred and twenty-six Korean patients with weekly typical GERD symptoms were asked to mark all food items that induced typical GERD symptoms from a list containing 152 typical foods consumed daily in Korea. All patients underwent upper gastrointestinal endoscopy followed by 24-hour ambulatory esophageal pH monitoring. The definition of “GERD” was if either of the 2 studies revealed evidence of GERD, and “possible GERD” if both studies were negative. RESULTS: One hundred and twenty-six cases (51 GERD and 75 possible GERD) were enrolled. In 19 (37.3%) of 51 GERD cases and in 17 (22.7%) of 75 possible GERD cases, foods inducing typical GERD symptoms were identified. In the GERD group (n = 19), frequent symptom-inducers were hot spicy stews, rice cakes, ramen noodles, fried foods, and topokki. In the possible GERD group (n = 17), frequent symptom-inducers were hot spicy stews, fried foods, doughnuts, breads, ramen noodles, coffee, pizza, topokki, rice cakes, champon noodles, and hotdogs. CONCLUSIONS: In one-third of GERD patients, foods inducing typical symptoms were identified. Hot spicy stews, rice cakes, ramen noodles, fried foods, and topokki were the foods frequently inducing typical symptoms in Korea. The list of foods frequently inducing typical GERD symptoms needs to be modified based on their own local experiences.

RESUMEN

Advances in imaging modalities have provided useful information in diagnosing ampullary lesions such as adenoma and adenocarcinoma. Endoscopic retrograde cholangiopancreaticography (ERCP) have a role in the diagnosis of unexposed intra-ampullarylesion. We report an interesting case of adenocarinoma of the ampulla of Vater presenting as idiopathic recurrent pancreatitis. A 56 years old woman was referred due to idiopathic recurrent pancreatitis for 2 years. She presented abdominal pain and upper abdominal tenderness. Magnetic resonance cholangiopancreaticography (MRCP) revealed minimal bile and pancreatic ductal dilatation without obstruction. Subsequent ERCP revealed a small polypoid lesion which was exposed after endoscopic sphincterotomy. Endoscopic biopsy showed papillary adenoma with low grade dysplasia. Additional endoscopic papillectomy was performed. Endoscopic biopsy done 3 months later showed papillary adenoma with high grade dysplasia. Pylorus preserving pancreatoduodenectomy was done and final pathology was well differentiated adenocarcinoma. The patient was recovered well but received adjuvant chemotherapy due to metastatic lymph nodes.

RESUMEN

BACKGROUND/AIMS: Astaxanthin is a carotenoid pigment that has antioxidant, antitumoral, and anti-inflammatory properties. In this in vitro study, we investigated the mechanism of anticancer effects of astaxanthin in gastric carcinoma cell lines. METHODS: The human gastric adenocarcinoma cell lines AGS, KATO-III, MKN-45, and SNU-1 were treated with various concentrations of astaxanthin. A cell viability test, cell cycle analysis, and immunoblotting were performed. RESULTS: The viability of each cancer cell line was suppressed by astaxanthin in a dose-dependent manner with significantly decreased proliferation in KATO-III and SNU-1 cells. Astaxanthin increased the number of cells in the G0/G1 phase but reduced the proportion of S phase KATO-III and SNU-1 cells. Phosphorylated extracellular signal-regulated kinase (ERK) was decreased in an inverse dose-dependent correlation with astaxanthin concentration, and the expression of p27(kip-1) increased the KATO-III and SNU-1 cell lines in an astaxanthin dose-dependent manner. CONCLUSIONS: Astaxanthin inhibits proliferation by interrupting cell cycle progression in KATO-III and SNU-1 gastric cancer cells. This may be caused by the inhibition of the phosphorylation of ERK and the enhanced expression of p27(kip-1).

RESUMEN

Melanocytic nevus is the benign proliferation of melanocytes. The most common location of melanocytic nevus is the skin of the extremities; however, there are few case reports of melanocytic nevus at the rectal mucosa. No prior case of malignant melanoma from melanocytic nevus at the rectal mucosa has been reported; therefore, it is unclear whether resection should be performed or close observation is sufficient. However, the potential malignant transformation of melanocytic nevus should be considered, including melanocytic nevus on the rectum. Melanocytic nevus of the skin can be removed by surgical excision; however, due to rare incidence on the mucosa of the gastrointestinal tract, the optimal treatment for rectal melanocytic nevus remains controversial. Here, we report the first case of melanocytic nevus on the rectal mucosa that was removed by endoscopic submucosal dissection. This case report provides useful information about the optimal management of rectal melanocytic nevus.

RESUMEN

BACKGROUND/AIMS: Prothrombin induced by vitamin K deficiency or antagonist II (PIVKA-II) is a widely used diagnostic marker for hepatocellular carcinoma (HCC). We evaluated the correlation between alcoholic liver disease (ALD) and serum PIVKA-II levels in chronic liver disease (CLD) patients. METHODS: We retrospectively reviewed the medical records of 2,528 CLD patients without HCC. Among these patients, 76 exhibited serum high PIVKA-II levels of >125 mAU/mL (group 1). We categorized 76 control patients matched by age, sex, and the presence of liver cirrhosis from the remaining patients who were negative for serum PIVKA-II (group 2). RESULTS: Group 1 revealed increased antibiotic usage (23.7% vs 2.6%, p<0.001) and incidence of ALD (60.5% vs 14.5%, p<0.001) as well as elevated aspartate aminotransferase (52.5 IU/L vs 30.5 IU/L, p=0.025) and gamma glutamyl transpeptidase (67.5 IU/L vs 36.5 IU/L, p=0.005) levels compared with group 2. Further, group 1 was significantly associated with a worse Child-Pugh class than group 2. In the multivariate analysis, ALD (odds ratio [OR], 7.151; p<0.001) and antibiotic usage (OR, 5.846; p<0.001) were significantly associated with positive PIVKA-II levels. CONCLUSIONS: Our study suggests that ALD and antibiotics usage may be confounding factors when interpreting high serum PIVKA-II levels in patients without HCC. Therefore, serum PIVKA-II levels in patients with ALD or in patients administered antibiotics should be interpreted with caution.

RESUMEN

BAome III criteria. METHODS: After EAR3Q was developed by Asian experts by cCKGROUND/AIMS: The development-processes by regional socio-cultural adaptation of an Enhanced Asian Rome III questionnaire (EAR3Q), a cultural adaptation of the Rome III diagnostic questionnaire (R3DQ), and its translation-validation in Asian languages are presented. As English is not the first language for most Asians, translation-validation of EAR3Q is essential. Hence, we aimed to culturally adapt the R3DQ to develop EAR3Q and linguistically validate it to show that the EAR3Q is able to allocate diagnosis according to Ronsensus, it was translated into Chinese, Hindi-Telugu, Indonesian, Korean, and Thai, following Rome Foundation guidelines; these were then validated on native subjects (healthy [n = 60], and patients with irritable bowel syndrome [n = 59], functional dyspepsia [n = 53] and functional constipation [n = 61]) diagnosed by clinicians using Rome III criteria, negative alarm features and investigations. RESULTS: Experts noted words for constipation, bloating, fullness and heartburn, posed difficulty. The English back-translated questionnaires demonstrated concordance with the original EAR3Q. Sensitivity and specificity of the questionnaires were high enough to diagnose respective functional gastrointestinal disorders (gold standard: clinical diagnoses) in most except Korean and Indonesian languages. Questionnaires often uncovered overlapping functional gastrointestinal disorders. Test-retest agreement (kappa) values of the translated questionnaires were high (0.700-1.000) except in Korean (0.300-0.500) and Indonesian (0.100-0.400) languages at the initial and 2-week follow-up visit. CONCLUSIONS: Though Chinese, Hindi and Telugu translations were performed well, Korean and Indonesian versions were not. Questionnaires often uncovered overlapping FGIDs, which were quite common.

RESUMEN

Small bowel tumors are very rare and generally malignant. As a result of the anatomical location and nonspecific manifestations of small bowel tumors, they are very difficult to diagnose. Balloon-assisted enteroscopy is a relatively noninvasive method compared to surgical resection, and allows for real-time observation, tissue confirmation with biopsy, and interventional procedures. Here, we report the case of a 69-year-old woman with a small bowel metastatic carcinoma observed with double balloon enteroscopy (DBE). She had a history of multiple cancers including ovarian cancer, bladder cancer, and breast cancer. The antegrade DBE procedure was performed before surgery for biopsy tissue confirmation. The patient underwent small bowel resection, and the final diagnosis was the same as that determined by preoperative biopsy. The final diagnosis was metastatic small bowel cancer originating from a cancer of the breast. This is the first detailed report of the preoperative diagnosis of small intestinal metastatic breast cancer by DBE.

RESUMEN

Infliximab is a chimeric anti-tumor necrosis factor-alpha monoclonal antibody. Infusion related reactions and infection are well known side effects of infliximab; however, renal complications have not been well recognized. We report on a patient with late onset-acute tubulointerstitial nephritis (ATIN) after treatment with infliximab and mesalazine for Crohn's disease. A 25-year-old woman was admitted with a purpuric rash on both lower extremities and arthralgia. She had been diagnosed with Crohn's disease 5.6 years previously and had been treated with mesalazine and infliximab. Serum creatinine level, last measured one year ago, was elevated from 0.6 mg/dL to 1.9 mg/dL. Results of urinalysis, ultrasound, and serologic examinations were normal. With a tentative diagnosis of Henoch-Schonlein purpura, oral prednisolone was given, and serum creatinine decreased to 1.46 mg/dL, but was elevated to 2.6 mg/dL again at two months after discontinuation of prednisolone. Renal biopsy indicated that ATIN was probably induced by drug, considering significant infiltration of eosinophils. Concomitant use of infliximab with mesalazine was supposed to trigger ATIN. Oral prednisolone was administered, and serum creatinine level showed partial recovery. Thus, ATIN should be suspected as a cause of renal impairment in Crohn's disease even after a long period of maintenance treatment with infliximab and mesalazine.

RESUMEN

BACKGROUND/AIMS: Nasogastric administration of cola for dissolution of phytobezoar was reported but the mechanism is not well understood. We aimed to evaluate the efficacy of cola ingestion for upper gastrointestinal endoscopy in patients who have had distal gastrectomy. MATERIALS AND METHODS: Patients were enrolled from July 2007 to October 2007 and all previously received subtotal gastrectomy. We conducted a randomized case-control study which the patients were randomly assigned to two groups. Group A had preparation with cola and group B had no preparation. Cola preparation group ingested about 1,500 mL of cola between 7 PM to 10 PM in the evening before the procedure. Two examiners who were blinded to the type of preparation performed the endoscopy. We assessed the degree of food residue and bile reflux by Japanese classification. RESULTS: A total of 70 patients were included. The comparison of clinical and laboratory characteristics between the two groups showed no statistically significant difference. During endoscopy, food residue was less found in group A than B, but without statistically significance (group A=12.1%, group B=21.6%, P=0.087). However, bile reflux was significantly less found in group A than B (group A=36.4%, group B=67.6%, P=0.015). Multivariate analysis, cola preparation significantly reduced food residue (OR, 0.032; P=0.001) and bile reflux (OR, 0.102; P=0.001). CONCLUSIONS: Preparation with cola in the evening before endoscopic examination may provide a good quality of preparation in patient with remnant stomach after distal gastrectomy.

RESUMEN

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.

RESUMEN

BACKGROUND/AIMS: To investigate the incidence of cholangiocarcinoma in patients with hepatolithiasis with or without previous resection of liver. METHODS: From 2002 to 2009, we retrospectively reviewed 117 patients who were diagnosed and treated for hepatolithiasis in Korea University Guro Hospital. Among the 117 patients, 55 patients who were lost during follow-up were excluded, and 62 patients were eligible for analysis. The hepatic resection group (n=25) included patients who underwent left hemihepatectomy (n=2); left lateral segmentectomy (n=10); left lobectomy (n=9); right lobectomy (n=3); or wedge resection (n=1). The nonhepatic resection group (n=37) included transhepatic cholangiographic lithotomy and endoscopic retrograde cholangiopancreatography-treated patients. The mean follow-up period was 47 months. RESULTS: The incidence of cholangiocarcinoma while patients were followed for hepatolithiasis was 12.9% (8/62) (hepatic resection group, three cases [12%] vs nonhepatic resection group, five cases [13.5%]; p=1.000). The mean follow-up period was 53 months (47+/-11 months) until the diagnosis of cholangiocarcinoma. CONCLUSIONS: There was no difference in the incidence of cholangiocarcinoma according to previous liver resections. Patients with hepatolithiasis should be carefully followed up for detection of cholangiocarcinoma even after a previous liver resection.

RESUMEN

BACKGROUND/AIMS: The use of self-expandable metallic stents (SEMS) is an established palliative treatment for malignant stenosis in the gastrointestinal tract; therefore, its application to benign stenosis is expected to be beneficial because of the more gradual and sustained dilatation in the stenotic portion. We aimed in this prospective observational study to evaluate the efficacy and safety of temporary SEMS placement in benign pyloric stenosis. METHODS: Twenty-two patients with benign stenosis of the prepylorus, pylorus, and duodenal bulb were enrolled and underwent SEMS placement. We assessed symptom improvement, defined as an increase of at least 1 degree in the gastric-outlet-obstruction scoring system after stent insertion. RESULTS: No major complications were observed during the procedures. After stent placement, early symptom improvement was achieved in 18 of 22 patients (81.8%). During the follow-up period (mean 10.2 months), the stents remained in place successfully for 6 to 8 weeks in seven patients (31.8%). Among the 15 patients (62.5%) with stent migration, seven (46.6%) showed continued symptomatic improvement without recurrence of obstructive symptoms. CONCLUSIONS: Despite the symptomatic improvement, temporary SEMS placement is premature as an effective therapeutic tool for benign pyloric stenosis unless a novel stent is developed to prevent migration.

RESUMEN

BACKGROUND/AIMS: Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder of the esophagus. Similar to asthma, EoE can induce irreversible structural changes in the esophagus as a result of chronic and persistent eosinophilic inflammation. The aim of this study was to analyse changes in symptoms, eosinophil counts and endoscopic findings after treatment. METHODS: Nine patients with EoE (6 men and 3 women; mean age, 36.44 years) were diagnosed with EoE based on typical symptoms, endoscopic abnormalities and infiltration of the esophageal epithelium with > or = 15 eosinophils/high-power field. The average endoscopic follow-up period was 10 months, ranging from 1 to 25 months. Symptoms and endoscopic and pathological findings at initial observation and follow-up were evaluated. RESULTS: Seven of the 9 patients had dysphagia symptoms, which improved in 4 of 6 patients who were treated with proton pump inhibitor. Two patients were unresponsive to proton pump inhibitor and another 2 patients were treated with corticosteroid, which led to symptomatic relief. In 8 patients, esophageal eosinophilia was improved histologically at follow-up after treatment. Six of the 9 patients had typical endoscopic findings of EoE at initial examination. Despite treatment, these findings remained in 5 of the 6 patients at follow-up endoscopy. CONCLUSIONS: After treatment, the symptoms and eosinophil counts were temporarily improved, but the endoscopic findings of EoE were generally not improved. This indicates that deformity of esophageal structure due to eosinophilic inflammation might be irreversible despite proper management.

RESUMEN

Inflammatory fibroid polyps are rare benign tumors of the GI tract, that commonly present with intestinal obstruction as a result of intussusceptions in the small bowel. A 39-year old man visited our clinic with an asymptomatic polypoid mass in the distal ileum that was identified on abdominal computed tomography for postoperative surveillance after total gastrectomy due to previously diagnosed early gastric cancer. Retrograde double-balloon enteroscopy was performed to diagnose the ileal mass and a complete resection of the polyp was performed using snare for polypectomy without complications. The final histological finding was an ileal inflammatory polyp. Balloon-assisted enteroscopy is a valuable modality to diagnose and treat small bowel lesions in lieu of surgical procedures in selected cases.

RESUMEN

BACKGROUND/AIMS: Endoscopic submucosal dissection (ESD) has been widely performed. However, procedure related-complications and the risk of tumor recurrence are limitations. We analyzed the clinicopathological characteristics of patients who underwent curative additional gastrectomy (gastrectomy) after ESD. METHODS: The clinical characteristics of cases underwent gastrectomy after ESD were retrospectively analyzed. RESULTS: Between January 2002 and August 2010, 1,512 cases underwent ESD for early gastric cancer (n=511) or adenoma (n=1,001). Thirty-two cases (2.1%) underwent gastrectomy after ESD. Thirty cases (2.0%) were EGC and 2 cases (0.1%) were adenoma. Extended indication, larger tumor size and piecemeal resection were risk factors for gastrectomy after ESD. According to the causes of gastrectomy, 13 cases underwent gastrectomy due to complications (40.6%; bleeding in 9, perforation in 4), and 19 cases based on pathological results (incomplete resection in 13, lymphatic invasion in 6). In cases with incomplete resection, the rate of residual tumor and lymph node metastasis after gastrectomy was 69.2% (75% lateral margin, 60% deep and 75% both) and 7.7%, respectively. Three (50%) of the 6 cases with lymphatic invasion had lymph node metatstasis. CONCLUSIONS: The causes of gastrectomy after ESD were the procedure-related complications, the incomplete resection and lymphatic invasion. For complete and curative ESD, endoscopists should try to minimize complications and determine the depth of invasion accurately before ESD.

RESUMEN

BACKGROUND/AIMS: Environmental factors such as food, lifestyle and prevalence of Helicobacter pylori infection are widely different in Asian countries compared to the West, and physiological functions and genetic factors of Asians may also be different from those of Westerners. Establishing an Asian consensus for functional dyspepsia is crucial in order to attract attention to such data from Asian countries, to articulate the experience and views of Asian experts, and to provide a relevant guide on management of functional dyspepsia for primary care physicians working in Asia. METHODS: Consensus team members were selected from Asian experts and consensus development was carried out using a modified Delphi method. Consensus teams collected published papers on functional dyspepsia especially from Asia and developed candidate consensus statements based on the generated clinical questions. At the first face-to-face meeting, each statement was reviewed and e-mail voting was done twice. At the second face-to-face meeting, final voting on each statement was done using keypad voting system. A grade of evidence and a strength of recommendation were applied to each statement according to the method of the GRADE Working Group. RESULTS: Twenty-nine consensus statements were finalized, including 7 for definition and diagnosis, 5 for epidemiology, 9 for pathophysiology and 8 for management. Algorithms for diagnosis and management of functional dyspepsia were added.

RESUMEN

Recent advances in endoscopic instruments, including narrow-band imaging (NBI) and magnification endoscopy, allowed dramatic increase in the early diagnosis of hypopharyngeal cancers. In addition, endoscopic mucosal resection or endoscopic submucosal dissection has recently been used for the treatment of hypopharyngeal cancer at an early stage, especially in Japan. However, to date, there is no published report in Korea. A 68-year-old man was admitted for preoperative evaluation and treatment for known esophageal cancer initially diagnosed at a local clinic. During the evaluation, magnifying endoscopy combined with the NBI system revealed a concurrent hypopharyngeal cancer not detected by initial conventional endoscopy. In this case report, we describe for the first time in Korea a case of early stage hypopharyngeal carcinoma that was successfully treated by endoscopic submucosal dissection with a review of literature.
