RESUMO
BACKGROUND AND AIM: While European Society of Pediatric Gastroenterology Hepatology and Nutrition advocates a no-biopsy pathway for the diagnosis of celiac disease (CeD) in children if IgA anti-tissue transglutaminase antibody (anti-tTG ab) titer is ≥10-fold upper limit of normal (ULN) and have a positive IgA anti-endomysial antibody (EMA); the data for anti-tTG Ab titer-based diagnosis of CeD in adults is still emerging. We planned to validate if IgA anti-tTG Ab titer ≥10-fold predicts villous abnormalities of modified Marsh grade ≥2 in Asian adult patients with CeD. METHODS: We recruited 937 adult patients with positive anti-tTG Ab from two databases, including AIIMS Celiac Clinic and Indian National Biorepository. The diagnosis of definite CeD was made on the basis of a positive anti-tTG Ab and the presence of villous abnormalities of modified Marsh grade ≥2. RESULTS: Of 937 adult patients with positive anti-tTG Ab, 889 (91.2%) showed villous abnormalities of modified Marsh grade ≥2. Only 47.6% of 889 adults with CeD had anti- tTG Ab titers of ≥10-fold. The positive predictive value (PPV) and specificity of anti tTG Ab titer ≥10-fold for predicting modified Marsh grade ≥2 were 99.8% and 98%, respectively. At anti-tTG Ab titer ≥11-fold, specificity and PPV were 100% for predicting villous abnormalities of modified Marsh grade ≥2. CONCLUSIONS: Approximately 50% of adults with CeD may benefit from the no biopsy pathway, reducing the health burden and risks of gastroscopy/anesthesia.

INTRODUCTION: Endoscopic dilation is the preferred management strategy for caustic esophageal strictures (CES). However, the differences in outcome for different dilators are not clear. We compared the outcome of CES using bougie and balloon dilators. METHODS: Between January 2000 and December 2016, the following data of all the patients with CES were collected: demographic parameters, substance ingestion, number of strictures, number of dilations required to achieve ≥ 14 mm dilation, post-dilation recurrence, and total dilations. Patients were divided into two groups for the type of dilator, i.e., bougie or balloon. The two groups were compared for baseline parameter, technical success, short- and long-term clinical success, refractory strictures, recurrence rates, and major complications. RESULTS: Of the 189 patients (mean age 32.17 ± 12.12 years) studied, 119 (62.9%) were males. 122 (64.5%) patients underwent bougie dilation and 67 (35.5%) received balloon dilation. Technical success (90.1% vs. 68.7%, p < 0.001), short-term clinical success (65.6% vs. 46.3%, p value 0.01), and long-term clinical success (86.9% vs. 64.2%, p < 0.01) were higher for bougie dilators compared to balloon dilators. Twenty-four (12.7%) patients developed adverse events which were similar for two groups. On multivariate analysis, use of bougie dilators (aOR 4.868, 95% CI 1.027-23.079), short-term clinical success (aOR 5.785, 95% CI 1.203-27.825), and refractory strictures (aOR 0.151, 95% CI 0.033-0.690) were independent predictors of long-term clinical success. CONCLUSION: Use of bougie dilators is associated with better clinical success in patients with CES compared to balloon dilators with similar rates of adverse events.

BACKGROUND: Timely intervention can alter outcome in patients of infected pancreatic necrosis (IPN) but lacks adequate biomarker. Role of serum procalcitonin (PCT) in the management of IPN is understudied, and hence, this study was planned. METHODOLOGY: All patients of acute pancreatitis with IPN without prior intervention were included. Baseline demographic, radiological and laboratory parameters were documented. PCT was measured at baseline, prior to intervention, and thereafter every 72 h. Patients were grouped into those having baseline PCT < 1.0 ng/mL and those with PCT ≥ 1.0 ng/mL and various outcome measures were compared. RESULTS: Of the 242 patients screened, 103 cases (66 males; 64.1%) with IPN were grouped into 2: PCT < 1.0 ng/mL (n = 29) and PCT ≥ 1.0 ng/mL (n = 74). Patients with baseline PCT ≥ 1.0 ng/mL had significantly more severe disease scores. 16 out of 19 patients with rise in PCT on day-7 post-intervention expired. PCT ≥ 1.0 ng/mL group had higher need for ICU (p = 0.001) and mortality (p = 0.044). PCT > 2.25 ng/mL (aOR 22.56; p = 0.013) at baseline and failure in reduction of PCT levels to < 60% of baseline at day-7 post-intervention (aOR 53.76; p = 0.001) were significant mortality predictors. CONCLUSION: Baseline PCT > 1.0 ng/mL is associated with poor outcome. PCT > 2.25 ng/mL and failure in reduction of PCT levels to < 60% of its baseline at day-7 post-intervention can identify high-mortality risk patients.

BACKGROUND: Patients with moderate-severe cholangitis require urgent/early biliary drainage and failed endoscopic retrograde cholangiopancreatography (ERCP) warrants use of percutaneous drainage. While endoscopic ultrasound-guided biliary drainage (EUS-BD) has evolved as an effective salvage modality but its safety and efficacy data in moderate-severe cholangitis are limited. PATIENTS AND METHODS: All consecutive moderate-severe cholangitis patients, with failed/technically non-feasible ERCP requiring EUS-BD in two tertiary care centers were included. Baseline laboratory and demographic parameters were documented. Technical and clinical success were primary outcome measures. Additionally, effective biliary drainage, adverse events due to procedure, hospital stay, ICU stay, and mortality were noted. RESULTS: Of the 49 patients (23 male; 46.9%) presenting with moderate/severe cholangitis, 23 (46.9%) had severe cholangitis. The median Charleston comorbidity index was 7.0 (IQR 2.0). Majority had malignant disease (87.8%) and 25 (51.0%) had inaccessible papilla. Technical success was achieved in 48 cases (98.0%), while clinical success with improvement of cholangitis was noted in 44 of 48 cases (91.7%). Effective biliary drainage was noted in 85.4% (41/48) cases. Adverse events in the form of mostly bleeding and bile leak were noted in 5 cases (10.2%) but managed conservatively. Distal obstruction exhibited significantly better clinical success (100% vs. 78.9%; p = 0.02) than hilar obstruction. Severe cholangitis had significantly lower clinical success (81.8% vs. 100%; p = 0.04) than moderate cholangitis. CONCLUSION: EUS-BD can be a safe and effective alternative option for patients with moderate to severe cholangitis, even with significant pre-morbid conditions, with acceptable adverse events rate.

BACKGROUND AND AIM: Prompt and accurate diagnosis of gastrointestinal tuberculosis (GITB) along with simultaneous detection of drug resistance is inevitable for tuberculosis elimination. Truenat MTB Plus (TruPlus), a chip-based real-time polymerase chain reaction assay, was evaluated for the first time for diagnosing GITB and detecting rifampicin resistance. METHODS: Fifty ileocecal biopsy specimens (5 microbiologically confirmed GITB [culture-positive], 25 clinically confirmed GITB [culture-negative], and 20 control patients) processed in the Department of Microbiology between 2011 and 2021 were subjected to TruPlus assay, Xpert MTB RIF assay multiplex polymerase chain reaction. Their performance was evaluated against both culture and composite reference standard. RESULTS: The overall sensitivity and specificity of TruPlus in diagnosing GITB was 70% (21/30) and 100%, respectively. The sensitivity was 60% (3/5) for microbiologically confirmed cases and 72% (18/25) for clinically confirmed cases. Performance of TruPlus was superior to Xpert (sensitivity = 30%; P = 0.001) and comparable with MPCR (sensitivity = 83.33%; P = 0.13). Both TruPlus and MPCR had moderate agreement with reference standards, and MPCR detected additional three cases. Both TruPlus and Xpert correctly reported Rifampicin resistance in three cases. CONCLUSIONS: TruPlus, with its greater portability and higher sensitivity than Xpert, could serve as an important tool for diagnosing GITB and rifampicin resistance at outreach endemic areas.

Inflammatory bowel disease (IBD), once considered a disease of the Western hemisphere, has emerged as a global disease. As the disease prevalence is on a steady rise, management of IBD has come under the spotlight. 5-Aminosalicylates, corticosteroids, immunosuppressive agents and biologics are the backbone of treatment of IBD. With the advent of biologics and small molecules, the need for surgery and hospitalization has decreased. However, economic viability and acceptability is an important determinant of local prescription patterns. Nearly one-third of the patients in West receive biologics as the first/initial therapy. The scenario is different in developing countries where biologics are used only in a small proportion of patients with IBD. Increased risk of reactivation of tuberculosis and high cost of the therapy are limitations to their use. Thiopurines hence become critical for optimal management of patients with IBD in these regions. However, approximately one-third of patients are intolerant or develop adverse effects with their use. This has led to suboptimal use of thiopurines in clinical practice. This review article discusses the clinical aspects of thiopurine use in patients with IBD with the aim of optimizing their use to full therapeutic potential.
RESUMO
Purpose Intraabdominal hypertension (IAH) in acute pancreatitis (AP) may reduce tissue perfusion and impair organ function and has been shown to portend poor prognosis. We investigated the computed tomography (CT) findings in patients with AP with IAH. Methods This retrospective study comprised of consecutive patients with AP from June 2016 to June 2018 in whom intraabdominal pressure (IAP) was measured. The patients who underwent a contrast-enhanced CT within 7 days of IAP measurement were included. Using a cutoff of 12 mm Hg for IAP, the patients were divided into IAH and non-IAH groups. Measures of severity and clinical outcome were evaluated. CT parameters were compared between the groups. Results The IAH group comprised of 41 patients, while there were 20 patients in the non-IAH group. The IAH group was characterized by severe disease, increased incidence of organ failure, increased requirement for drainage and surgery, prolonged hospital and intensive care unit stay. The mortality was not significantly different between the two groups. On univariate analysis, the CT features that were found to be significantly different between the two groups were the presence of collection ( p = 0.036), the maximum dimension of collection ( p = 0.004), volume of collection ( p = 0.019), biliary dilatation ( p = 0.011), and the presence of moderate-to-severe pleural effusion ( p = 0.009). On multivariate analysis, all these parameters except biliary dilatation were found to be statistically significant. Conclusion CT findings in patients with AP may suggest IAH. This can be used as an additional marker for severity of AP.
RESUMO
Cardiac lymphoma is a rare entity. In this setting, the secondary involvement of the heart is far more frequent than the primary cardiac lymphoma. Herein, we present an autopsy case of a disseminated anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma with a dominant mediastinal involvement. Extensive cardiac infiltration with the near replacement of the myocardial wall by the neoplastic cells was observed. A total of nine isolated case reports of anaplastic large cell lymphoma with cardiac involvement were found in the English-language literature, and a widespread cardiac and thymic infiltration by the systemic ALK-positive anaplastic large cell lymphoma has not been documented. An incidental regenerative nodule was also identified in the liver. The patient died of pulmonary thromboembolism and cardiac arrest.
RESUMO
OBJECTIVE: Comparison of virtual CT enteroscopy (VCTE) using carbon dioxide with small-bowel enteroclysis (SBE) and capsule endoscopy (CE) in small-bowel tuberculosis (SBTB). METHODS: This prospective study comprised consecutive patients suspected to have SBTB. VCTE and SBE were performed on the same day and evaluated by independent radiologists. CE was performed within 2 weeks. VCTE was performed following insufflation of carbon dioxide via catheters in the jejunum and anorectum. A contrast-enhanced CT was followed by a delayed non-contrast CT. Image processing was done using virtual colonoscopy software. Findings on VCTE, SBE, and CE were compared. The final diagnosis of SBTB was based on either histopathological or cytological findings, response to antitubercular treatment, or a combination of these. RESULTS: Of the 55 patients in whom VCTE was performed, complete data was available in 52 patients. A final diagnosis of SBTB was established in 37 patients. All patients had VCTE and SBE. CE was performed in 34 patients. Adequate luminal distension was achieved in all patients with SBE and 35 patients with VCTE. SBE showed more strictures in jejunum (10.8%) and ileum (75.7%) compared with VCTE (jejunum, 8.1%, and ileum, 64.9%) and CE (jejunum, 5.9%, and ileum, 61.8%). However, difference was not statistically significant. VCTE revealed a greater length of strictures in both the jejunum and ileum compared with SBE and CE. CONCLUSION: VCTE allows adequate evaluation of the bowel in most patients with SBTB. It allows detection of greater length of abnormality in jejunum and ileum compared with SBE and CE. KEY POINTS: ⢠The use of VCTE using CO2 bowel insufflation in patients with SBTB should be considered. ⢠VCTE allows detection of a greater length of abnormality in the jejunum and ileum.

BACKGROUND: Aorto-oesophageal fistula (AOF) is a rare, catastrophic disease with an extremely poor prognosis. A ruptured thoracic aortic aneurysm is a common aetiology for AOF. The clinical presentation is usually massive haematemesis and collapse. Timely diagnosis and appropriate treatment are crucial in managing AOF. CASE SUMMARY: We hereby report two cases of AOF, who underwent successful emergency thoracic endovascular aortic repair (TEVAR) to control active bleed and exsanguination. Case 1, an elderly lady with atherosclerotic aneurysm had TEVAR followed by open surgery for oesophageal rent and necrosed left main bronchus. Case 2 had mycotic tubercular aneurysm who later had infected graft-stent following TEVAR. DISCUSSION: Open surgery is the conventional treatment for AOF; however, TEVAR can be an alternative and less invasive approach in selected high-risk patients. Various management issues related to TEVAR with AOF have been discussed in the article.
RESUMO
BACKGROUND: Prompt and accurate diagnosis of gastrointestinal tuberculosis (GITB) is highly challenging. Current conventional techniques lack sensitivity and are time-consuming. Multi targeted loop-mediated isothermal amplification (LAMP) using two targets (IS6110 and MPB64) is a promising technique for rapid diagnosis of TB. METHODS: LAMP test using IS6110 and MPB64 targets for M. tuberculosis complex was performed on ileocecal biopsy samples of 35 clinically suspected patients of GITB and 30 ileocecal biopsy samples of non-tuberculosis control subjects. Results of IS6110 LAMP and MPB64 LAMP were compared with IS6110 PCR and culture INFERENCE: Overall LAMP test (using any of the two targets) had a sensitivity and specificity of 100 and 100%, respectively, for confirmed GITB (five culture positive) cases and 85.71 and 100%, respectively, for clinically suspected 30 ileocecal biopsy samples of GITB. Sensitivity of IS6110 LAMP, MPB64 LAMP and IS6110 PCR for clinically suspected cases was 22 (73.33%), 24 (80%) and 21 (70%), respectively. In total 35 GITB patients, the overall sensitivity of microscopy, culture, IS6110 PCR, IS6110 LAMP, MPB64 LAMP and the multi-targeted LAMP assay (if any of the two targets were used) were 5.71, 14.28, 68.57, 74.28, 82.85 and 85.71%, respectively. Specificity of all the tests was 100%. There were three cases which were missed by IS6110 LAMP and two cases by MPB64 LAMP. CONCLUSION: Multi-targeted LAMP is a promising technique for rapid and accurate diagnosis of GITB.

BACKGROUND AND AIMS: This retrospective study was aimed at assessing the efficacy of endoscopic dilation for esophageal anastomotic strictures, and to compare response between caustic anastomotic strictures (CAS) and non-caustic anastomotic strictures (NCAS). MATERIALS AND METHODS: Patients with anastomotic strictures (enrolled during January 1996-December 2015) were analyzed. Short- and long-term outcomes of dilation, in terms of clinical success, refractory, and recurrent strictures were compared between NCAS and CAS. Patients with refractory and recurrent strictures were managed with adjunctive therapy including intralesional steroids. Factors predicting refractoriness at start of dilation and reasons for more than ten lifetime dilations were also evaluated. RESULTS: Of the 142 patients, 124 (mean age-44.02; males-74) underwent dilation. Clinical success was achieved in 113 (91.3%) patients requiring a median [Interquartile range (IQR)] of 4 (2-10) sessions. The number of dilations to achieve clinical success, refractory strictures, and recurrent strictures, and the use of adjunctive therapy were significantly higher for CAS than for NCAS. Intralesional steroid use decreased periodic dilation index (PDI) significantly in CAS. Caustic etiology and starting dilation diameter of < 10 mm were found to be predictors of refractoriness, with the former alone being an independent predictor of more than ten lifetime dilations. No patient had free perforation; however, five required revision surgery. CONCLUSION: Patients with CAS fared worse than those with NCAS in terms of number of dilations, refractoriness, recurrence of strictures, and need of adjunctive therapy. Endoscopic dilation can successfully ameliorate dysphagia due to anastomotic strictures in a majority of patients.

BACKGROUNDS/AIMS: Residual gallbladder mucosa left after subtotal/partial cholecystectomy is prone to develop recurrent lithiasis and become symptomatic, which mandates surgical removal. METHODS: We retrospectively evaluated the patients with residual gallbladder referred to us from January 2011 to December 2017. Based on MRCP we classified calot's anatomy to - type I where cystic duct was seen and type II where sessile GB stump was seen. RESULTS: 21 patients with median age 38 years and M:F::1:9.5, had undergone cholecystectomy (3 months-20 years) prior, presented with recurrent biliary pain. 3 had jaundice (CBD stone, Mirizzi and biliary stricture), 1 had pancreatitis and one had malignancy of the GB. Imaging revealed type I anatomy in 14 (67%) and type II in 7 (33%). All underwent completion cholecystectomy - open in 18 and laparoscopic in 3 (one converted to open). Additional procedure was required in 5 patients - CBD exploration in 2 (10%) and one each Hepatico-jejunostomy, extended cholecystectomy and splenectomy. Median hospital stay was 1 day. There was no mortality and 10% morbidity. One patient with malignancy died at 2 years, two died of unrelated cause, one developed incisional hernia and the remaining were well at a median follow up of 29 months. CONCLUSIONS: Residual GB lithiasis should be suspected if there are recurrent symptoms after cholecystectomy. MRCP based proposed classification can guide the management strategy. Completion cholecystectomy is curative.
RESUMO
Caustic esophageal strictures are complex strictures with high rates of recurrence and complications. Management of these strictures requires a multipronged approach including endoscopic dilation and complex surgeries. Even with these modalities, treatment of each patient has to be individualized because it requires high clinical discretion. We present a 38-year-old female woman who had required esophagostomy and total gastrectomy in the acute phase after caustic ingestion. The definitive surgical procedure was deferred because of cicatrization of the proximal esophageal remnant. We remodeled scarred esophagus using a novel technique, which facilitated definitive surgery.
RESUMO
INTRODUCTION: These Asian Working Group guidelines on diet in inflammatory bowel disease (IBD) present a multidisciplinary focus on clinical nutrition in IBD in Asian countries. METHODOLOGY: The guidelines are based on evidence from existing published literature; however, if objective data were lacking or inconclusive, expert opinion was considered. The conclusions and 38 recommendations have been subject to full peer review and a Delphi process in which uniformly positive responses (agree or strongly agree) were required. RESULTS: Diet has an important role in IBD pathogenesis, and an increase in the incidence of IBD in Asian countries has paralleled changes in the dietary patterns. The present consensus endeavors to address the following topics in relation to IBD: (i) role of diet in the pathogenesis; (ii) diet as a therapy; (iii) malnutrition and nutritional assessment of the patients; (iv) dietary recommendations; (v) nutritional rehabilitation; and (vi) nutrition in special situations like surgery, pregnancy, and lactation. CONCLUSIONS: Available objective data to guide nutritional support and primary nutritional therapy in IBD are presented as 38 recommendations.

BACKGROUND AND AIMS: Peptic ulcer disease (PUD)-related gastric outlet obstruction (GOO) is known to respond favorably to endoscopic balloon dilation (EBD). However, data on efficacy of EBD for other etiologies of benign GOO are sparse. We aimed to compare the response of EBD among different etiologies of GOO. METHODS: Records of all patients with benign GOO who underwent EBD at our tertiary-care center between January 1998 and December 2017 were analyzed. Dilation was done by using through-the-scope balloons. Procedural and clinical success of EBD was compared among different etiologies. RESULTS: A total of 306 patients were evaluated, of whom 264 (mean [± standard deviation] [SD] age 37.89 ± 17.49 years; men 183, women 81) underwent dilation. Etiologically, caustic ingestion was the commonest cause of GOO (53.8%) followed by PUD (26.1%) and medication-induced (8.3%). Overall procedural and clinical success was achieved in 200 (75.7%) and 243 (92.04%) patients, respectively, requiring a mean (± SD) of 2.55 (2.8) and 5.37 (3.9) sessions, respectively. Caustic-induced GOO responded less favorably, requiring a higher number of dilation sessions and having more refractory strictures than other etiologies. Medication-induced GOO performed worse than PUD-related GOO. Of the 264 patients, 9 (3.4%) had perforations during EBD, 3 had contained leaks and were managed conservatively, and 6 underwent successful surgery. CONCLUSION: EBD is successful in a majority of patients with benign GOO, with caustic-induced GOO and medication-induced GOO being more difficult than PUD-related GOO.

BACKGROUND: Disease activity in ulcerative colitis (UC) is best assessed clinically by Mayo score. 18-Fluorodeoxyglucose positron emission tomography-computerized tomography (FDG PET-CT) is a noninvasive imaging technique to assess extent, disease activity and response to treatment of UC, especially in high risk population or patients unwilling for endoscopy. AIMS: We conducted a prospective observational study with the aim of assessing and correlating UC disease activity by clinical criteria, endoscopy, histology, serum and fecal biomarkers, and FDG PET-CT. METHODS: Sixty eligible patients of UC were enrolled into three groups (26 remission, 24 moderate and 10 severe activity) as per Mayo score and FDG PET-CT was performed within 72 h of colonoscopy. ESR, CRP, and fecal calprotectin (FC) levels were determined for all patients. RESULTS: Of 60 enrolled patients, 10% patients had proctitis, 43.3% left-sided colitis, and 46.7% extensive colitis. ESR, CRP, FC levels, and rectal PET activity were significantly higher in groups with moderate and severe disease activity. Rectal PET activity showed a significant correlation with the Mayo score (k = 0.465, p < 0.001), endoscopic subscore (k = 0.526, p < 0.001), histological score (k = 0.496, p < 0.001), and FC (k = 0.279, p = 0.031). Extent evaluation by FDG PET-CT and colonoscopy showed a significant correlation (k = 0.582, p < 0.001). Besides, FDG PET-CT identified sacroiliitis in one patient and adenocarcinoma in one patient. CONCLUSION: FDG PET-CT is a reliable noninvasive tool for detection of disease activity, extent in UC with good correlation with Mayo score, histology and fecal biomarkers and accurate predictor of disease remission.
