RESUMO
Background and objective Patients with suspected malignant biliary strictures frequently undergo endoscopic retrograde cholangiopancreatography (ERCP)-based brush cytology and endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) for establishing the diagnosis. The outcomes of these tests aid in the further management of the patient. A comparison of these two modalities in establishing the diagnosis is seldom reported. In light of this, we aimed to compare the diagnostic efficacy between ERCP-based brush cytology and EUS-FNA for tissue diagnosis in malignant biliary obstruction. Our study involved a retrospective audit of all patients admitted to the Vydehi Institute of Medical Sciences and Research Centre for EUS and ERCP from 2015 to 2019. Methodology A Comparative study was conducted in the Department of Medical Gastroenterology at the Vydehi Institute of Medical Sciences and Research Centre over a five-year period. A total of 77 subjects who presented during the study period with biliary obstruction based on clinical presentation with altered liver function test in an obstructive pattern and evidence of biliary obstruction in the form of stricture or pancreaticobiliary mass on cross-sectional imaging were included in the study. All the patients included in the study underwent EUS and ERCP. Results The majority of the patients in the study were in the fifth decade of life with a slight female predominance. The most common CT finding was a periampullary mass with common bile duct (CBD) stricture (59.7%). In the study, EUS-FNA was more sensitive than ERCP-based tissue sampling. The overall sensitivity was 90.63% for EUS-FNA and 65.63% for ERCP sampling. EUS-FNA was found to have diagnostic accuracy of 92.63% in comparison to 71.43% for brush cytology. Conclusions Based on our findings, EUS-FNA is superior to ERCP-based tissue sampling with excellent sensitivity and diagnostic accuracy. Performing EUS before ERCP in all patients with suspected malignant biliary obstruction would definitely improve diagnostic accuracy and thereby help in the management of such cases.
RESUMO
The Indian Society of Gastroenterology developed this evidence-based practice guideline for management of gastroesophageal reflux disease (GERD) in adults. A modified Delphi process was used to develop this consensus containing 58 statements, which were generated by electronic voting iteration as well as face-to-face meeting and review of the supporting literature primarily from India. These statements include 10 on epidemiology, 8 on clinical presentation, 10 on investigations, 23 on treatment (including medical, endoscopic, and surgical modalities), and 7 on complications of GERD. When the proportion of those who voted either to accept completely or with minor reservation was 80% or higher, the statement was regarded as accepted. The prevalence of GERD in India ranges from 7.6% to 30%, being < 10% in most population studies, and higher in cohort studies. The dietary factors associated with GERD include use of spices and non-vegetarian food. Helicobacter pylori is thought to have a negative relation with GERD; H. pylori negative patients have higher grade of symptoms of GERD and esophagitis. Less than 10% of GERD patients in India have erosive esophagitis. In patients with occasional or mild symptoms, antacids and histamine H2 receptor blockers (H2RAs) may be used, and proton pump inhibitors (PPI) should be used in patients with frequent or severe symptoms. Prokinetics have limited proven role in management of GERD.

Isolated pancreatic injury is uncommon and the management is challenging. Presentation is mostly delayed in such cases. We report a case of 26-year-old male, who was referred to our centre due to blunt abdominal trauma of 48 h duration with pain abdomen and vomiting. He was haemodynamically stable and was subjected to endoscopy after few hours of admission, but failed to cannulate the main pancreatic duct. Successful stenting was performed after 3 days of admission in the second attempt. He made an uneventful recovery and remains well 2 months after the injury. Management of isolated pancreatic injuries with complete duct disruption is challenging. Endoscopic management is an attractive minimally invasive option which avoids the need for surgery. Further studies are required regarding the selection of patients, safety and long-term outcome.
RESUMO
BACKGROUND AND AIM: Intra-abdominal lymphadenopathy poses a diagnostic and management challenge in highly endemic regions for tuberculosis. Opting for empirical anti-tuberculosis treatment raises the risk of wrong or delayed treatment. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the procedure of choice for tissue acquisition from peri-luminal lymph nodes. We studied the utility of EUS-FNA in evaluating intra-abdominal lymph nodes of unknown etiology, in the setting of high endemicity of tuberculosis. METHODS: Consecutive patients with intra-abdominal lymph nodes of unknown etiology underwent EUS-FNA using a 22-gauge needle. Final diagnosis was made on surgical histology or on 6-months follow-up. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and diagnostic yield were calculated. RESULTS: Sixty-six patients were included. Final diagnoses were tuberculosis, 35 (53%); metastatic adenocarcinoma, 11 (16.7%); lymphoma, three (4.5%); carcinoid, one (1.5%) and reactive nodes, 16 (24.2%). EUS-FNA provided a diagnosis in 61 patients (92.4%). Sensitivity, specificity, PPV and NPV for diagnosing tuberculosis via EUS-FNA were 97.1%, 100%, 100% and 96.9%, respectively. In 10 (15.2%) patients receiving empirical anti-tuberculosis treatment, the final diagnoses were metastatic adenocarcinoma (5), lymphoma (2), carcinoid (1) and reactive adenopathy (2). CONCLUSION: Despite being in a highly endemic area, almost half of the patients studied have a non-tuberculosis etiology. EUS-FNA is a safe and accurate procedure for establishing the diagnosis of unexplained intra-abdominal lymphadenopathy.

BACKGROUND AND AIMS: Barrett's esophagus (BE) is reported to be infrequent in Asians, with no data from India regarding its prevalence and risk factors. We investigated the frequency and risk factors of columnar mucosa with or without specialized intestinal metaplasia (SIM) in Indian patients with gastroesophageal reflux disease (GERD). METHODS: A total of 278 GERD patients over 2 years underwent gastroscopy and completed a questionnaire for possible BE risk factors. Patients with columnar mucosa on endoscopy underwent four-quadrant biopsy; BE was histologically defined as columnar mucosa with or without SIM. Patients without columnar mucosa at endoscopy were considered as controls and compared to patients with BE and those with SIM. RESULTS: Forty-six patients with GERD had columnar mucosa on histology (16.54%); 25 (8.99%) of these had SIM. The risk factors for BE were the presence of hiatus hernia (odds ratio [OR]: 3.14; 95% confidence interval [CI]: 1.2-8.17) and a history of eructation (OR: 2.28; CI: 1.11-4.66). The risk factors for SIM were age ≥ 45 years (OR: 2.63; CI: 1.03-6.71), hiatus hernia (OR: 3.95; CI: 1.24-12.56), and a history of eructation (OR: 3.41; CI: 1.19-9.78). Sex, severity of symptoms, dietary factors, tobacco or alcohol use, and body mass index were not associated with BE. The median circumferential segment length was 2 (1-10) cm, and the maximal length was 3 (2-11) cm in both groups. CONCLUSION: BE is not an uncommon finding among Indian GERD patients. Age ≥ 45 years, history of eructation, and the presence of hiatus hernia are associated with SIM.
