Background Encapsulated pancreatic fluid collection (PFC) is a requisite for endoscopic drainage procedures. The 4-week threshold for defining walled-off necrosis does not capture the dynamic process of encapsulation. We aim to investigate the changes in the wall characteristics of PFC in acute necrotizing pancreatitis (ANP) by comparing baseline contrast-enhanced computed tomography (CECT) with follow-up CT scans.

Background The role of dual-modality drainage of walled-off necrosis (WON) in patients with acute pancreatitis (AP) is established. However, there are no data on the association of clinical outcomes with the timing of percutaneous catheter drainage (PCD). We investigated the impact of the timing of PCD following endoscopic drainage of WON on clinical outcomes in AP.

Purpose Critically ill patients with acute pancreatitis (AP) require intensive care unit (ICU) admission. The management of pancreatic fluid collections (PFCs) in this group is challenging. We aimed to evaluate the feasibility and safety of bedside percutaneous ultrasound (USG)-guided interventions in necrotic PFC in ICU patients. Methods This retrospective study comprised consecutive patients with AP in the ICU who underwent bedside USG-guided interventions for necrotic PFC. Indications for intervention, technical success, clinical success, and complications were recorded. The site, number, and size of catheters were recorded. Clinical outcomes were assessed. Results Thirty-three patients (mean age, 38.1 years, 15 females) were included. All patients had nonresolving organ failure and were on mechanical ventilation. The mean pain to percutaneous catheter drainage (PCD interval was 42.2 days (range, 7–167 days). All the procedures were technically successful, and none of the patients required shifting to the interventional radiology suite for computed tomography guidance. PCD was clinically successful in 40% of the patients. There were no major complications. The mean length of hospital stay and ICU stay was 35 days (range, 6–69 days) and 13 days (range, 1–63 days), respectively. Six (17.1%) patients underwent necrosectomy. Sixteen (45.7%) patients died in the hospital. Conclusion USG-guided bedside PCD can be performed safely with high technical success in the ICU setting.

Background: Peroral endoscopic myotomy (POEM) is an established modality of treatment for achalasia cardia. Considerable variations exist in the technique of POEM with respect to the length and orientation of the myotomy. In this systematic review and meta-analysis, we compared the outcomes of short versus long myotomy during POEM. Methods: We searched multiple databases from January 2010 to March 2021 to identify studies reporting on POEM. We selected studies that reported on comparative outcomes of POEM using short versus long myotomy. We performed a comparative analysis of clinical success, procedural duration, gastroesophageal reflux disease (GERD), and adverse events with short and long myotomy in POEM by meta-analysis. Results: A total of 521 patients from five studies in which 241 patients were treated with short and 280 patients with long myotomy approaches were analyzed. The pooled rate for clinical success gave an odds ratio (OR) of 1.27 (95% confidence interval [CI] 0.50–3.26; I2 = 0; P = 0.62); for hospital stay OR 0.22 (95% CI − 0.03 to 0.46; I2 = 0; P = 0.08); for GERD by esophagogastroduodenoscopy (EGD) OR 0.58 (95% CI 0.31–1.07; I2 = 0; P = 0.08), and for adverse events OR 0.67 (95% CI 0.29–1.53; I2 = 51; P = 0.34). Abnormal esophageal acid exposure was less frequent with OR 0.45 (95% CI 0.22–0.90; P = 0.02; I2 = 0) and the procedure duration was significantly shorter in the short myotomy group with OR − 0.76 (95% CI − 1.00 to − 0.52; I2 = 43; P =0.001). Conclusion: Short myotomy and long myotomy in POEM seem comparable with each other in terms of clinical success and adverse events. Short myotomy is associated with significantly shorter procedural duration and possibly reduced esophageal acid exposure compared with long myotomy.

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.

Background The Mayo endoscopic score (MES) remains the most commonly used index in clinical practice, as well as in various clinical trials. Recently, two validated histological indices (Nancy Index [NI] and Robert Histological Index [RHI]) have been developed for ulcerative colitis (UC). We aim to study the relationship between MES with NI, RHI, and the established Geboes Index (GI) in patients with UC. Methods This was a prospective single‐center study. MES was documented from the most involved area. Biopsy was taken from the same area and reported by a single gastrointestinal histopathologist who was blinded to the endoscopic score. Histological activity was reported using GI, NI, and RHI. Statistical analysis was performed using Spearman's correlation coefficient and Cohen's kappa coefficient using SPSS version 23. Results Median age of patients with UC (n = 96) was 36 years. Seventeen patients were in endoscopic remission (MES 0/1). Correlation coefficient between MES and GI/NI/RHI was only weak to moderate (rho = 0.381/0.389/0.442, respectively; P

Pancreatitis is one of the important medical conditions. Gastrointestinal (GI) complications of pancreatitis are important and lead to significant morbidity and mortality. Diagnosis of these complications is difficult and may require a strong clinical suspicion coupled with various imaging features. This review provides an extensive update of the whole spectrum of GI complication of pancreatitis, both acute and chronic, from inflammation, ischemia, and necrosis to obstruction, perforation, and GI fistulae. The focus is on the clinical and imaging features of this less commonly described aspect of pancreatitis.

Intestinal involvement in Behcet's disease (BD) is uncommon. Differentiating it from close mimics like Crohn's Disease is difficult. Further, in asymptomatic cases, diagnostic challenges posed is still greater. A 17‐year‐old boy had history of recurrent oro‐genital ulcers, papulo‐pustular skin eruptions, ocular lesions and had presented with recent onset perianal abscess. Fecal calprotectin was elevated, and ileo‐colonoscopy showed ileocolonic ulcers of inflammatory nature. Clinical diagnosis of intestinal BD was made. Patients with BD having mucosal lesions may harbor asymptomatic intestinal lesions. Screening them with fecal calprotectin levels and if positive, with subsequent imaging and endoscopic biopsy with timely initiation of appropriate treatment in such asymptomatic cases help to control overall disease activity.

Esophagobronchial fistula is an uncommon complication of esophageal or mediastinal tuberculosis. A 35‑year‑old man, a known case of esophageal tuberculosis, who had received 9 months of antitubercular therapy (ATT) presented with persistent cough. He had previously been detected to have an esophagobronchial fistula for which multiple hemoclips had been applied elsewhere, but the fistula persisted. A fistulous communication between the esophagus and the left main bronchus was successfully closed with the help of over‑the‑scope‑clip (OTSC) system. The present case is unique as patient developed fistulous communication during the treatment with ATT and it persisted despite successful treatment of esophageal tuberculosis. Moreover, this refractory fistula could be successfully closed with OTSC.
