RESUMO
BACKGROUND: Hepatic fibrosis and secondary biliary cirrhosis are consequences of long-standing benign biliary strictures. Evidence on the reversibility of fibrosis after the repair is incongruous. METHODOLOGY: A prospective observational study on patients who underwent Roux-en-Y hepaticojejunostomy for benign biliary stricture. A liver biopsy was performed during repair and correlated with preoperative elastography. The improvement in liver functions and regression of fibrosis was compared with preoperative liver function tests and elastography. RESULTS: A Total of 47 patients [mean age-38.9 y (Range: 21 to 66)] with iatrogenic benign biliary stricture were included. A strong female preponderance was noted. High strictures (type III and IV) comprised 72.7% of the study group. The median interval (injury to repair) was 7 months (2 to 72 mo). The median duration of jaundice was 3 months (1 to 20 mo). Both factors had a significant correlation with the stage of fibrosis ( P =0.001 and P =0.03, respectively). Liver biopsy revealed stage I, II, III, and IV fibrosis in 26 (55.3%), 11 (23.4%), 2 (4.3%), and 2(4.3%), respectively. The remaining 6 (12.8%) had no fibrosis. The severity of fibrosis had a good correlation with preoperative liver stiffness measurement-value on FibroScan. Significant improvement in liver function tests (bilirubin-3.55±3.48 vs. 0.59±0.52; Albumin-3.85±0.61 vs. 4.14±0.37; ALP-507.66±300.65 vs. 167±132.07; P value 0.00) and regression of fibrosis (liver stiffness measurement; 10.42±5.91 vs. 5.85±3.01, P value 0.00) was observed after repair of the strictures. CONCLUSION: Improved biliary function and regression of liver fibrosis can be achieved with timely repair of benign biliary stricture and it is feasible to be evaluated using elastography.

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.

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.

Pancreatic fistula is a highly morbid complication of pancreatitis. External pancreatic fistulas result when pancreatic secretions leak externally into the percutaneous drains or external wound (following surgery) due to the communication of the peripancreatic collection with the main pancreatic duct (MPD). Internal pancreatic fistulas include communication of the pancreatic duct (directly or via intervening collection) with the pleura, pericardium, mediastinum, peritoneal cavity, or gastrointestinal tract. Cross-sectional imaging plays an essential role in the management of pancreatic fistulas. With the help of multiplanar imaging, fistulous tracts can be delineated clearly. Thin computed tomography sections and magnetic resonance cholangiopancreatography images may demonstrate the communication between MPD and pancreatic fluid collections or body cavities. Endoscopic retrograde cholangiography (ERCP) is diagnostic as well as therapeutic. In this review, we discuss the imaging diagnosis and management of various types of pancreatic fistulas with the aim to sensitize radiologists to timely diagnosis of this critical complication of pancreatitis.

BACKGROUND AND AIM: Emergence of drug resistance, especially to second-line drugs, hampers tuberculosis elimination efforts. The present study aimed to evaluate MTBDRplus and MTBDRsl assays for detecting first-line and second-line drug resistance, respectively, in gastrointestinal tuberculosis (GITB). METHODS: Thirty ileocecal biopsy specimens, processed in the Department of Microbiology between 2012 and 2022, that showed growth of Mycobacterium tuberculosis on culture were included in the study. DNA, extracted from culture, was subjected to MTBDRplus and MTBDRsl (Hain Lifescience GmbH, Nehren, Germany), following manufacturer's instructions. Their performance was compared against phenotypic drug susceptibility testing (pDST) and gene sequencing. RESULTS: Out of the 30 specimens, 4 (13.33%) were mono-isoniazid resistant, 4 (13.33%) were multidrug resistant (MDR), 2 (6.67%) were pre-extensively drug resistant (pre-XDR), and 2 (6.67%) were mono-fluoroquinolone resistant. The results were 100% concordant with pDST and gene sequencing. CONCLUSIONS: In the wake of growing drug resistance in all forms of extrapulmonary tuberculosis, including GITB, MTBDRplus and MTBDRsl are reliable tools for screening of resistance to both first-line and second-line drugs.

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: Acute pancreatitis remains the most common and morbid complication of endoscopic retrograde cholangiopancreatography (ERCP). The use of rectal indomethacin and pancreatic duct stenting has been shown to reduce the incidence and severity of post-ERCP pancreatitis (PEP), but these interventions have limitations. Recent clinical and translational evidence suggests a role for calcineurin inhibitors in the prevention of pancreatitis, with multiple retrospective case series showing a reduction in PEP rates in tacrolimus users. METHODS: The INTRO trial is a multicenter, international, randomized, double-blinded, controlled trial. A total of 4,874 patients undergoing ERCP will be randomized to receive either oral tacrolimus (5 mg) or oral placebo 1-2 h before ERCP, and followed for 30 days post-procedure. Blood and pancreatic aspirate samples will also be collected in a subset of patients to quantify tacrolimus levels. The primary outcome of the study is the incidence of PEP. Secondary endpoints include the severity of PEP, ERCP-related complications, adverse drug events, length of hospital stay, cost-effectiveness, and the pharmacokinetics, pharmacodynamics, and pharmacogenomics of tacrolimus immune modulation in the pancreas. CONCLUSIONS: The INTRO trial will assess the role of calcineurin inhibitors in PEP prophylaxis and develop a foundation for the clinical optimization of this therapeutic strategy from a pharmacologic and economic standpoint. With this clinical trial, we hope to demonstrate a novel approach to PEP prophylaxis using a widely available and well-characterized class of drugs. TRIAL REGISTRATION: NCT05252754, registered on February 14, 2022.

OBJECTIVE: To evaluate the role of contrast-enhanced ultrasound (CEUS) in the differential diagnosis of solid pancreatic head lesions (SPHL). METHODS: This prospective study comprised consecutive patients with SPHL who underwent CEUS evaluation of the pancreas. Findings recorded at CEUS were enhancement patterns (degree, completeness, centripetal enhancement, and percentage enhancement) and presence of central vessels. In addition, time to peak (TTP) and washout time (WT) were recorded. The final diagnosis was based on histopathology or cytology. Multivariate analysis was performed to identify parameters that were significantly associated with pancreatic ductal adenocarcinoma (PDAC). RESULTS: Ninety-eight patients (median age 53.8 years, 59 males) were evaluated. The final diagnosis was PDAC (n = 64, 65.3%), inflammatory mass (n = 16, 16.3%), neuroendocrine tumor (NET, n = 14, 14.3%), and other tumors (n = 4, 4.1%). Hypoenhancement, incomplete enhancement, and centripetal enhancement were significantly more common in PDAC than non-PDAC lesions (p = 0.001, p = 0.031, and p = 0.002, respectively). Central vessels were present in a significantly greater number of non-PDAC lesions (p = 0.0001). Hypoenhancement with < 30% enhancement at CEUS had sensitivity and specificity of 80.6% and 67.7%, respectively, for PDAC. There was no significant difference in the TTP and WT between PDAC and non - PDAC lesions. However, the WT was significantly shorter in PDAC compared to NET (p = 0.011). In multivariate analysis, lack of central vessels was significantly associated with a PDAC diagnosis. CONCLUSION: CEUS is a useful tool for the evaluation of SPHL. CEUS can be incorporated into the diagnostic algorithm to differentiate PDAC from non-PDAC lesions. KEY POINTS: ⢠Hypoenhancement and incomplete enhancement at CEUS were significantly more common in PDAC than in non-PDAC. ⢠Central vessels at CEUS were significantly associated with PDAC. ⢠There was no difference in TTP and WT between PDAC and non-PDAC lesions.

BACKGROUND: There is an emerging role of fungal dysbiosis in the pathogenesis of inflammatory bowel disease. Prevalence of Candida in patients with active ulcerative colitis (UC) and the effect of fluconazole therapy in reducing disease activity of UC are not known. PATIENTS AND METHODS: All consecutive consenting patients with active UC defined as Mayo score ≥3 were evaluated for presence of Candida by stool culture and predictors for presence of Candida were identified. Those who had evidence of Candida in the stool were randomized to receive oral fluconazole 200 mg daily or placebo for 3 weeks along with standard medical therapy. Patients were assessed by clinical, sigmoidoscopy, and laboratory parameters at baseline and at 4 weeks. The primary outcome was clinical and endoscopic response at 4 weeks defined by a 3-point reduction in Mayo score. Secondary outcomes were reduction in fecal calprotectin, histologic response, and adverse events. RESULTS: Of the 242 patients with active UC, 68 (28%) patients had Candida in stool culture. Independent predictors for presence of Candida in patients with active UC were partial Mayo score of ≥3 and steroid exposure. Among those with Candida on stool culture (n=68), 61 patients fulfilled eligibility criteria and were randomized to receive fluconazole (n=31) or placebo (n=30). Three-point reduction in Mayo score though was numerically higher in the fluconazole group than the placebo group but was not statistically significant [5 (16.1%) vs. 1 (3.33%); P =0.19]. Postintervention median Mayo score was lower in fluconazole than placebo group [4 (3, 5) vs. 5 (4, 6); P =0.034]. Patients in fluconazole group had more often reduction in fecal calprotectin [26 (83.9%) vs. 11 (36.7%); P =0.001] and histologic scores [23 (74.1%) vs. 10 (33.3%); P =0.001] compared with placebo. All patients were compliant and did not report any serious adverse event. CONCLUSION: Candida colonization is found in 28% of patients with UC. Steroid exposure and active disease were independent predictors for the presence of Candida . There was no statistically significant difference in the number of patients who achieved 3-point reduction in Mayo score between 2 groups. However, clinical, histologic, and calprotectin levels showed significant improvement in fluconazole group.

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.

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.

OBJECTIVE: Acute pancreatitis (AP) is a common disorder with high mortality in severe cases. Several markers have been studied to predict development of severe AP (SAP) including serum resistin with conflicting results. This study aimed at assessing the role of baseline serum resistin levels in predicting SAP. METHODS: This prospective study collected data from 130 AP patients from July 2017 to Nov 2018. Parameters measured included demographic profile, serum resistin at admission, severity scores, hospital stay, surgery, and mortality. Patients were divided into two groups, severe and non-severe AP. The two groups were compared for baseline characteristics, serum resistin levels, hospital stay, surgery and mortality. RESULTS: Among 130 patients, 53 patients had SAP. SAP patients had higher BMI, baseline CRP, APACHE II and CTSI scores (p-value 0.045, <0.001, <0.001 and 0.001, respectively). Both groups had comparable serum resistin levels. Serum resistin levels were also not different for obese and non-obese patients (p-value = 0.62). On multivariate analysis, BMI and high APACHE II score and CRP levels were found to independently predict SAP. CONCLUSION: We found that serum resistin is not a useful marker for predicting the severity of AP and does not correlate with increasing body weight.

BACKGROUND: Percutaneous catheter drainage (PCD) is an effective way of drainage in acute pancreatitis (AP) and its role in persistent organ failure (OF) has not been studied. This study assessed the outcome of severe AP managed with PCD. METHODS: We retrospectively analysed outcome of AP patients undergoing PCD for persistent OF with respect to success of PCD, etiology, severity scores, OF, imaging features and PCD parameters. Success of PCD was defined as resolution of with PCD and survived without surgical necrosectomy. RESULTS: Between January 2016 and May 2018, 83 patients underwent PCD for persistent OF at a mean duration of 25.59 ± 21.2 days from pain onset with successful outcome in 47 (56.6%) patients. Among PCD failures, eleven (13.25%) patients underwent surgery. Overall mortality was 31 (37.3%). On multivariate analysis, pancreatic necrosis <50% and absence of extrapancreatic infection (EPI) predicted the success of PCD. Presence of infected necrosis did not affect the outcome of PCD in organ failure. CONCLUSION: PCD improves the outcome in patients with OF even when done early irrespective of the status of infection of necrosis. Therefore, PCD may be considered early in the course of patients with OF.

OBJECTIVES: To study the natural course of patients with acute pancreatitis (AP) with acute kidney injury (AKI) and their cytokine profile. METHODS: Natural course of patients with AP and AKI was studied in 97 individuals. Levels of TNFα, IL-6, IL-10, IL-8 and IL-1ß were measured at presentation and at 72 h in patients who developed AKI. RESULTS: Amongst the entire cohort, 16.4% patients developed AKI (persistent AKI - 11 patients, transient AKI - 5 patients). Mortality rate was 25% amongst patients with AKI. Levels of IL-6 (p = 0.035) and IL-8 (p = 0.002) were found to be significantly higher in the AKI group. On multivariate analysis, IL-8 levels at baseline were found to be an independent predictor of AKI. AKI group had significant rise of TNF-α (P < 0.001), IL-6 (P < 0.001) and IL- 1ß (P < 0.001) on day 3 whereas persistent-AKI group had significant rise of TNF-α (p = 0.031), IL-6 (p = 0.001) and IL-1ß on day 3 and significant decline of IL-10 (p = 0.015). Using a cut-off of 105 pg/ml, IL-8 levels at baseline could predict AKI with a sensitivity of 87.5% and specificity of 59.2%, with area under the curve being 0.744 (p = 0.002). CONCLUSION: AP patients developing AKI have poor prognosis. IL-8 levels can predict AKI in patients with AP.

BACKGROUND: The site and size of extrapancreatic necrosis (EPN) as assessed on computed tomography may influence the severity of acute necrotizing pancreatitis (ANP). The objective of the study was to evaluate the impact of site and size of EPN on the clinical outcomes in patients with acute necrotizing pancreatitis (ANP). METHOD AND MATERIALS: This retrospective study comprised of consecutive patients with ANP who were admitted between January 2017 and March 2019. Patients in whom the initial contrast enhanced CT showed EPN were eligible for inclusion. The site, volume and maximum dimension of EPN were recorded. The severity of AP and modified CT severity index (MCTSI) was calculated. Clinical outcomes were recorded. RESULTS: A total of 119 patients (mean age, 37.56 years, 91 males) were included. There was a significant association between the location of EPN and the outcome parameters. The left posterior pararenal collections were significantly associated with mortality (P = 0.041), left paracolic gutter collections with the length of hospitalisation (LOH) (P = 0.014), and right paracolic gutter and mesenteric collections with the intensive care unit (ICU) stay (P = 0.024, and P = 0.021, respectively). There was a significant correlation between the volume and the maximum dimension of collection with LOH and ICU stay. The area under the receiver operating characteristic curve for volume, maximum dimension and MCTSI for predicting death was 0.724 (95% CI, 0.612-0.837), 0.644 (95% CI, 0.516-0.772) and 0.574 (95% CI, 0.452-0.696), respectively. CONCLUSION: The site and size of EPN provide reliable and objective information for assessing clinical outcomes in patients with ANP.

OBJECTIVE: Intra-abdominal hypertension (IAH) can adversely affect the outcome in patients of acute pancreatitis (AP). Effect of percutaneous drainage (PCD) on IAH has not been studied. We studied the effect of PCD on IAH in patients with acute fluid collections. MATERIAL AND METHODS: Consecutive patients of AP undergoing PCD between Jan 2016 and May 2018 were evaluated for severity markers, clinical course, hospital and ICU stay, and mortality. Patients were divided into two groups: with IAH and with no IAH (NIAH). The two groups were compared for severity scores, organ failure, hospital and ICU stay, reduction in IAP and mortality. RESULTS: Of the 105 patients, IAH was present in 48 (45.7%) patients. Patients with IAH had more often severe disease, BISAP ≥2, higher APACHE II scores and computed tomography severity index (CTSI). IAH group had more often OF (87.5% vs. 70.2%, p = 0.033), prolonged ICU stay (12.5 vs. 6.75 days, p = 0.007) and higher mortality (52.1% vs. 15.8%, p < 0.001). After PCD, IAP decreased significantly more in the IAH group (21.85 ± 4.53 mmHg to 12.5 ± 4.42 mmHg) than in the NIAH group (12.68 ± 2.72 mmHg to 8.32 ± 3.18 mmHg), p = <0.001. Reduction of IAP in patients with IAH by >40% at 48 h after PCD was associated with better survival (63.3% vs. 36.7%, p = 0.006). CONCLUSION: We observed that patients with IAH have poor outcome. PCD decreases IAP and a fall in IAP >40% of baseline value predicts a better outcome after PCD in patients with acute fluid collections.

BACKGROUND: Percutaneous catheter drainage (PCD) performed pro-actively for collections in acute pancreatitis (AP) is associated with better outcomes. However, there are only a few studies describing this protocol. AIM: We aimed to evaluate an aggressive PCD protocol. METHODS: Consecutive patients with AP who underwent PCD with an aggressive protocol between January 2018 and January 2019 were included. This protocol involved catheter upsizing at a pre-specified interval (every 4-6 days) as well as drainage of all the new collections. The indications and technical details of PCD and clinical outcomes were compared with patients who underwent standard PCD. RESULTS: Out of the 185 patients with AP evaluated during the study period, 110 (59.4%) underwent PCD, all with the aggressive protocol. The historical cohort of standard PCD comprised of 113 patients. There was no significant difference in the indication of PCD and interval from pain onset to PCD between the two groups. The mean number of catheters was significantly higher in the aggressive PCD group (1.86 ± 0.962 vs. 1.44 ± 0.667, p = 0.002). Additional catheters were inserted in 54.2% of patients in aggressive group vs. 36.2% in the standard group (p = 0.006). Length of hospital stay and intensive care unit (ICU) stay were significantly longer in the standard PCD group (34.3 ± 20.14 vs. 27.45 ± 14.2 days, p < 0.001 and 10.46 ± 12.29 vs. 4.12 ± 8.5, p = 0.009, respectively). There was no significant difference in mortality and surgery between the two groups. CONCLUSION: Aggressive PCD protocol results in reduced length of hospital stay and ICU stay and can reduce hospitalization costs.

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.
