Role of interventional endoscopic ultrasound in a developing country

Background/Aims@#Endoscopic ultrasound (EUS) has become an essential diagnostic and therapeutic tool. EUS was introduced in 2013 in Indonesia and is considered relatively new. This study aimed to describe the current role of interventional EUS at our hospital as a part of the Indonesian tertiary health center experience. @*Methods@#This retrospective study included all patients who underwent interventional EUS (n=94) at our center between January 2015 and December 2020. Patient characteristics, technical success, clinical success, and adverse events associated with each type of interventional EUS procedure were evaluated. @*Results@#Altogether, 94 interventional EUS procedures were performed at our center between 2015 and 2020 including 75 cases of EUS-guided biliary drainage (EUS-BD), 14 cases of EUS-guided pancreatic fluid drainage, and five cases of EUS-guided celiac plexus neurolysis. The technical and clinical success rates of EUS-BD were 98.6% and 52%, respectively. The technical success rate was 100% for both EUS-guided pancreatic fluid drainage and EUS-guided celiac plexus neurolysis. The adverse event rates were 10.6% and 7.1% for EUS-BD and EUS-guided pancreatic fluid drainage, respectively. @*Conclusions@#EUS is an effective and safe tool for the treatment of gastrointestinal and biliary diseases. It has a low rate of adverse events, even in developing countries.

Best practices on immunomodulators and biologic agents for ulcerative colitis and Crohn's disease in Asia

The Asia-Pacific Working Group on inflammatory bowel disease (IBD) was established in Cebu, Philippines, under the auspices of the Asian Pacific Association of Gastroenterology with the goal of improving IBD care in Asia. This consensus is carried out in collaboration with Asian Organization for Crohn's and Colitis. With biologic agents and biosimilars becoming more established, it is necessary to conduct a review on existing literature and establish a consensus on when and how to introduce biologic agents and biosimilars in the conjunction with conventional treatments for ulcerative colitis (UC) and Crohn's disease (CD) in Asia. These statements also address how pharmacogenetics influence the treatments of UC and CD and provide guidance on response monitoring and strategies to restore loss of response. Finally, the review includes statements on how to manage treatment alongside possible hepatitis B and tuberculosis infections, both common in Asia. These statements have been prepared and voted upon by members of IBD workgroup employing the modified Delphi process. These statements do not intend to be all-encompassing and future revisions are likely as new data continue to emerge.

Differences in the insulin resistance levels measured by HOMA-IR between patients with erosive and non-erosive gastroesophageal reflux disease / Journal of the ASEAN Federation of Endocrine Societies

Background@#Insulin resistance is the core of Metabolic Syndrome which carries a high risk for cardiovascular events. Insulin resistance had been reported to be higher in GERD patients than subjects without GERD, specifically in erosive esophagitis. @*Objective@#To compare the degree of insulin resistance, using HOMA-IR index, between erosive and non-erosive reflux disease. @*Methodology@#A cross-sectional study of 84 adult patients with GERD symptoms was conducted. The subjects were recruited consecutively between January 2017 and April 2017 at Cipto Mangunkusumo National Hospital in Jakarta. Gastroesophageal Reflux Disease Questionnaire (GERDQ) was used for subject recruitment. Homeostatic model assessment-insulin resistance (HOMA-IR) index was used to evaluate insulin sensitivity. Esophageal erosions were diagnosed using upper gastrointestinal endoscopy. Bivariate analysis was used to determine HOMA-IR difference between esophagitis and non-esophagitis group. @*Results@#The median of HOMA-IR in all subjects was 1.46 (0.32-13.85). Mann-Whitney test revealed that HOMA-IR index was higher in patients with erosive esophagitis [median 1.74 (0.35-13.85)] than those without erosive esophagitis [median 1.21 (0.32-10.78)] (p=0.05). @*Conclusion@#Insulin resistance is significantly higher in gastroesophageal reflux disease patients with esophageal erosions than in those without esophageal erosion.

Development, Translation and Validation of Enhanced Asian Rome III Questionnaires for Diagnosis of Functional Bowel Diseases in Major Asian Languages: A Rome Foundation-Asian Neurogastroenterology and Motility Association Working Team Report

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.

Primary Care Management of Chronic Constipation in Asia: The ANMA Chronic Constipation Tool

Chronic constipation (CC) may impact on quality of life. There is substantial patient dissatisfaction; possible reasons are failure to recognize underlying constipation, inappropriate dietary advice and inadequate treatment. The aim of these practical guidelines intended for primary care physicians, and which are based on Asian perspectives, is to provide an approach to CC that is relevant to the existing health-care infrastructure. Physicians should not rely on infrequent bowel movements to diagnose CC as many patients have one or more bowel movement a day. More commonly, patients present with hard stool, straining, incomplete feeling, bloating and other dyspeptic symptoms. Physicians should consider CC in these situations and when patients are found to use laxative containing supplements. In the absence of alarm features physicians may start with a 2-4 week therapeutic trial of available pharmacological agents including osmotic, stimulant and enterokinetic agents. Where safe to do so, physicians should consider regular (as opposed to on demand dosing), combination treatment and continuous treatment for at least 4 weeks. If patients do not achieve satisfactory response, they should be referred to tertiary centers for physiological evaluation of colonic transit and pelvic floor function. Surgical referral is a last resort, which should be considered only after a thorough physiological and psychological evaluation.

Molecular profile of colorectal cancer in Indonesia: is there another pathway?

Colorectal cancer is an emerging public health problem in Indonesia and currently ranks among the three highest cancers. Lack of a colonoscopy screening and lifestyle changes might contribute to it. In the last few decades, there is an increasing interest towards the contribution of genetic-environment interaction in colorectal carcinogenesis. Some studies have indicated that CRC might develop through several different pathways; the three major routes are chromosomal instability [CIN], microsatellite instability [MSI], and inflammatory pathways. An earlier study on clinical epidemiology of CRC in Indonesia showed that the majority of patients were diagnosed between 45 and 50 years old, with a mean age around 47 years old. Further studies showed that most young Indonesian cases of CRC do not have hereditary characteristics; however, the CRC did not follow the conventional pathways of sporadic CRC [the CIN] pathway. Rather, it is a mixed of MSI and inflammatory pathways. Immunohistochemical studies showed that the proportion of patients with negative mismatch repair proteins was 43.5% for MSH2 and 83.5% for MLH1. Along the sporadic colorectal carcinogenesis pathway, there was a specific role of cyclooxygenase-2 [COX-2] enzyme during the polyp formation. COX-2 expression was reported in about 80% CRC cases worldwide. However, our study found only 49% of COX-2 expression among the CRC patients. Interestingly, an inflammatory marker, the nucleus factor [k]B [NF-[k]B], was expressed in about 73.5% cases, in line with a previous study. More recently, KRAS has been used as a potential tumor marker to select treatment and its expression was reported to be as high as 30%-40% worldwide. However, we found that KRAS gene expression was only 16.3%. Our findings support that CRC patients in Indonesian might follow a distinct pathway, a hypothesis that deserves further exploration
