Validation of no-biopsy pathway for the diagnosis of celiac disease in Asian adults: a multicenter retrospective study.

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.

Impact of delay in the diagnosis on the severity of celiac disease.

BACKGROUND AND AIM: Celiac disease (CeD) has now become a global disease with a worldwide prevalence of 0.67%. Despite being a common disease, CeD is often not diagnosed and there is a significant delay in its diagnosis. We reviewed the impact of the delay in the diagnosis on the severity of manifestations of CeD. METHODS: We reviewed clinical records of 726 consecutive patients with CeD from the Celiac Clinic database and the National Celiac Disease Consortium database. We extracted specific data including the demographics, symptoms at presentation, time of onset of symptoms, time to diagnosis from the onset of the symptoms, and relevant clinical data including fold-rise in anti-tissue transglutaminase antibody (IgA anti-tTG Ab) and severity of villous and crypt abnormalities as assessed using modified Marsh classification. RESULTS: The median duration between the onset of symptoms and the diagnosis of CeD was 27 months (interquartile range 12-60 months). A longer delay in the diagnosis of CeD from the onset of symptoms was associated with lower height for age, lower hemoglobin, higher fold rise in IgA Anti tTG titers, and higher severity of villous and crypt abnormalities. About 18% of patients presented with predominantly non-gastrointestinal complaints and had a longer delay in the diagnosis of CeD. CONCLUSIONS: There is a significant delay in the diagnosis of CeD since the onset of its symptoms. The severity of celiac disease increases with increasing delay in its diagnosis. There is a need to keep a low threshold for the diagnosis of CeD in appropriate clinical settings.

Endoscopic dilation with bougies versus balloons in caustic esophageal strictures: 17-year experience from a tertiary care center.

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.

Dynamics of Serum Procalcitonin Can Predict Outcome in Patients of Infected Pancreatic Necrosis: A Prospective Analysis.

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.

EUS-guided biliary drainage in patients with moderate-severe cholangitis is safe and effective: a multi-center experience.

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.

Evaluating diagnostic performance of Truenat MTB Plus for gastrointestinal tuberculosis.

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.

Comparison of virtual computed tomography enteroscopy using carbon dioxide with small-bowel enteroclysis and capsule endoscopy in patients with small-bowel tuberculosis.

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.

Outcomes of Endoscopic Dilation in Patients with Esophageal Anastomotic Strictures: Comparison Between Different Etiologies.

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.

Ascites in acute pancreatitis: not a silent bystander.

BACKGROUND & AIM: Ascites in patients with acute pancreatitis (AP) is understudied although recent literature hints at its evident role in the final outcome. This study was planned to study the characteristics of ascites in patients of AP and its effect on the disease course and outcome. METHODS: Consecutive patients of AP were studied and patients with or without ascites were evaluated for the baseline parameters and severity assessment. Ascites was quantified and fluid analyzed for its characteristics. Intraabdominal pressure (IAP) was monitored. The various outcome parameters were compared between the two groups of patients with and without ascites. RESULTS: Of the cohort of 213 patients, 82 (38.5%) developed ascites. Ascites group had significantly higher rates of organ failure (p = 0.001), necrosis (p=<0.001) and higher severity assessment scores. The ascites group had significantly longer hospital and ICU stay and higher ventilator days compared to the non-ascites group. Mortality was also higher in the ascites group (34.1% vs 8.45; p = 0.001). Majority of patients with ascites had moderate to gross ascites (75.6%), low serum ascites albumin gradient (87.8%) with low amylase levels (71.9%). Sub-group analysis in ascites group showed that patients with fatal outcome had higher rates of moderate to gross ascites, higher baseline IAP and lower reduction in IAP after 48 h. Moderate to gross ascites and grades of intra-abdominal hypertension (IAH) were significant predictors of mortality (AUC - 0.76). CONCLUSION: AP patients with ascites have a more severe disease with poorer outcome. Higher degrees of ascites and IAH grades are significant predictors of mortality.

Etiological spectrum and response to endoscopic balloon dilation in patients with benign gastric outlet obstruction.

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.

Role of Positron Emission Tomography in Assessing Disease Activity in Ulcerative Colitis: Comparison with Biomarkers.

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.

Association of Serotonin Transporter Promoter Polymorphism (5-HTTLPR) with Microscopic Colitis and Ulcerative Colitis.

BACKGROUND: Serotonin (5-HT) release and serotonin reuptake transporter (5-HTT) expression have been reported to be decreased in experimental colitis, in interleukin-10 knockout-associated colitis, and in patients with ulcerative colitis. Serotonin is known to play an important role in the pathogenesis of colitis, but individual genetic variants of 5-HTT gene in microscopic colitis and ulcerative colitis are not known. AIM: This study aimed to evaluate the association between the serotonin transporter gene promoter polymorphism (5-HTTLPR) and 5-HT concentration in microscopic colitis (MC) and ulcerative colitis (UC) patients. METHOD: This prospective case-control study included 41 patients with microscopic colitis (age 19-82 years, mean 35 ± 13.6), 75 patients with ulcerative colitis (age 16-65 years, mean 38.5 ± 11.6), and 100 controls (age 20-64 years, mean 38 ± 11). 5-HTTLPR gene polymorphism was studied by polymerase chain reaction-based assay. 5-HT levels were measured by ELISA. RESULTS: The frequency of the 5-HTTLPR (SS) genotype was significantly lower in MC (12 %) patients compared to controls (30 %) (p < 0.05). When the L/L and L/S genotypes were combined into one group, the frequencies of the non-S genotype were significantly higher than those of S/S genotype between the MC patients and the controls (p < 0.05). 5-HT levels were significantly higher in UC and MC patients compared to healthy controls (p < 0.01). CONCLUSIONS: A significant association was observed between LL genotype of 5-HTTLPR polymorphism and microscopic colitis, suggesting that 5-HTTLPR is a potential candidate gene involved in the pathogenesis of microscopic colitis. Serotonin levels were significantly higher in microscopic colitis and ulcerative colitis patients compared to healthy controls.

Radiological findings in duodenal tuberculosis: a 15-year experience.

OBJECTIVE: To evaluate the radiological findings of duodenal tuberculosis with particular emphasis on the barium findings. MATERIAL AND METHODS: A retrospective analysis of 805 cases of gastrointestinal tuberculosis from January 1997 to December 2011 over a period of 15 years was conducted. Thirty two cases (4%) of duodenal tuberculosis were found. The diagnosis of duodenal tuberculosis was based on histopathology following surgery or endoscopic biopsy from the duodenum, ultrasound-guided aspiration cytology/biopsy of lymph nodes or response to anti-tubercular treatment. The patients' clinical presentation was broadly classified into obstructive features and dyspeptic features. Single and/ or double contrast upper gastrointestinal barium studies were reviewed in each case for the segment involved, presence and length of strictures, ulcerations, polypoidal masses, extrinsic impression and complications (viz. perforations and fistulae). RESULTS: The study included 20 males and 12 females with age range of 7-70 years (mean age 26.6 years) Twenty-seven (84.3%) patients presented with obstructive symptoms and five (15.6%) had predominantly dyspeptic symptoms. The radiological findings in patients with obstructive symptoms were duodenal strictures (n = 19), extrinsic compression (n = 10) and polypoidal intraluminal mass with luminal narrowing (n = 3). Among the patients presenting with dyspeptic symptoms, the most common findings was duodenal ulcerations (n = 3). Perforation was seen in 4 cases and fistulisation in 2 cases. A multiplicity of findings was noted in 7 patients. CONCLUSION: Barium studies though not specific for duodenal tuberculosis helped to delineate the mucosal lesions and define the nature, level, and extent of obstruction in these patients.

Role of endoscopic retrograde cholangiography in ruptured hepatic hydatid cyst.

AIM: To report endoscopic retrograde cholangiopancreatography (ERCP) findings of intrabiliary hydatid cyst rupture. MATERIAL AND METHODS: A retrospective study of cases with intrabiliary rupture of hydatid cyst was conducted. A total of 4 cases (all female with a mean age of 32 years) were included. ERCP and ultrasound data were evaluated. Assessment involved number, location, size, internal and wall characteristics of cyst; intrahepatic biliary radicle dilatation (IHBRD); common bile duct (CBD) dilatation and evidence of extrabiliary rupture on ultrasound. ERCP evaluation included IHBRD, CBD dilatation, communication between cysts and intrahepatic biliary radicles (IHBR) and filling defects within the IHBR and CBD. Treatment details were also obtained. RESULTS: A total of 5 cysts were evaluated in 4 patients. Left lobe cysts were most common (n=4). Segment II/III were the most commonly affected segments (n=3). Cyst outline was smooth and cystobiliary communication noted in all cases. Deformation of cyst wall was noted in 2 cases. Isolated (left or right) IHBRD lateralised to the side of the cyst was most common (n=4). CBD dilatation was seen in all cases with a mean calibre of 1.4 cm. Concomitant extrabiliary rupture was seen in 3 cases. Endoscopic management was done in all cases without complications. Three patients underwent surgical excision after a mean period of 8 weeks following ERCP. CONCLUSION: Isolated IHBRD lateralized to the side of hydatid cyst with CBD dilatation is the commonest ERCP finding of intrabiliary rupture of hydatid cyst.

Primary versus secondary achalasia: A diagnostic conundrum.

A coherent distinction between primary and secondary achalasia is considerably important to clinicians. This is because the therapeutic interventions for the two are entirely different. Whilst pneumatic dilation is the standard treatment in primary achalasia, the same treatment, if instituted in malignant stenosis carries potential risk to the patient and delays appropriate therapy of the underlying disorder. This distinction however, is extremely difficult. None of the available clinical, manometric, endoscopic or imaging criteria can reliably exclude secondary achalasia. However, suspicion may be raised and in such cases, an exhaustive work up including repeat biopsies and even surgery should be considered. In this review, we discuss the various problems in differentiating primary from secondary achalasia.

Clinical presentation and outcome of endoscopic therapy in patients with symptomatic chronic pancreatitis associated with pancreas divisum.

CONTEXT: The results of endoscopic drainage in pancreas divisum with chronic pancreatitis have been debatable. OBJECTIVE: To evaluate clinical presentation and long term results of endoscopic therapy in patients of calcific and non-calcific chronic pancreatitis with pancreas divisum. PATIENTS AND METHODS: Between 1996 and 2011, 48 patients (32 males and 16 females) with chronic pancreatitis and pancreas divisum were treated endoscopically. Patients were considered to have clinical success if they had resolution of symptoms and did not require surgery. RESULTS: All patients presented with abdominal pain and symptoms were present for 36.6 ± 40.5 months. Pseudocyst, diabetes, pancreatic ascites, pancreatic pleural effusion, segmental portal hypertension and steatorrhea were seen in 13 (27.1%), 6 (12.5%), 3 (6.3%), 2 (4.2%), 2 (4.2%) and 1 (2.1%) patients, respectively. Ductal calculi and strictures were noted in 3 (6.3%) and 2 (4.2%) patients, respectively. In 47 patients, an endoprosthesis (5 or 7 Fr) was successfully placed in the dorsal duct. Following pancreatic endotherapy, 45/47 (95.7%) patients had successful outcome. The mean number of stenting sessions required to have clinical success was 2.6 ± 0.9. One patient each had mild post ERCP pancreatitis, inward migration of stent and precipitation of diabetic ketoacidosis. Over a follow up of 2-174 months (median: 67 months), 12 out of 31 patients with pain only and no local complications (38.7%) required restenting for recurrence of pain and none of these patients required surgery. CONCLUSION: Intensive pancreatic endotherapy is safe and effective both in patients with chronic calcific, as well as non-calcific, pancreatitis associated with pancreas divisum. It gives good long term response in patients having abdominal pain and/or dorsal ductal disruptions.

Diastolic dysfunction, prolonged QTc interval and pericardial effusion as predictors of mortality in acute pancreatitis.

BACKGROUND AND AIM: The cardiac changes in acute pancreatitis have been earlier studied but the data on their prognostic significance is limited. This study was done to determine electrocardiographic (ECG) and echocardiographic changes in acute pancreatitis and determine their prognostic significance. METHODS: Fifty-two consecutive patients (mean age 36.5 ± 11 years (44 males)) with acute pancreatitis and without prior cardiovascular comorbidites were prospectively enrolled and subjected to clinical, laboratory and radiological investigation. ECG and echocardiography was done at admission and during follow up. RESULTS: Seventeen patients (32.7%) had mild pancreatitis and 35 (67.3%) patients had severe pancreatitis. Sinus tachycardia was the most common ECG abnormality. QTc prolongation was seen in 30/52 (57.7%) patients. On echocardiography, no patient had systolic dysfunction but 31/52 (59.6%) patients had diastolic dysfunction. All 22 patients with QTc interval < 440 ms survived compared with 8/30 patients with QTc interval ≥ 440 ms who died (P = 0.01). All eight patients who died had evidence of diastolic dysfunction (100%). None of the patients without diastolic dysfunction succumbed to illness (P = 0.02). Pericardial effusion was present in 6/52 (11.5%) patients. Of the eight patients who died, pericardial effusion was present in three (37.5%) patients and this frequency was significantly higher than that in patients who recovered (3/44 [6.8%]; P = 0.04). CONCLUSION: Electrocardiographic and echocardiographic changes are seen in more than 50% of patients with acute pancreatitis. Prolonged QTc interval, pericardial effusion and diastolic dysfunction are associated with higher mortality.
