Low prevalence of Clostridioides difficile infection in acute severe ulcerative colitis: A retrospective cohort study from northern India
Background The incidence of Clostridioides difficile infection (CDI) is high in ulcerative colitis and is associated with disease flares and adverse outcomes. However, the data on the dynamics of CDI in patients with acute severe ulcerative colitis (ASUC) is rather scarce. We evaluated the prevalence of CDI in patients with ASUC. Methods This retrospective analysis of a prospectively maintained cohort admitted to the All India Institute of Medical Sciences, India, from May 2016 to December 2021, included patients with ASUC (as per Truelove and Witts criteria) who were tested for CDI. CDI testing was performed using enzyme-linked immunoassay for toxins A and B. Risk factors for developing CDI were analyzed along with short-term outcomes of ASUC. Steroid failure was defined as the need for medical rescue therapy or colectomy. Results Total 153 patients with ASUC were included (mean age 34.92 ± 12.24 years; males 56.2%; disease duration 36 (IQR: 16–55.5) months, pancolitis 67.3%). Ninety-eight (63.4%), 72 (47%) and 10 (6.5%) patients, respectively, had received steroids, azathioprine and biologics in the past. Forty patients (26.14%) had a prior history of ASUC. Among risk factors for CDI, 14% of the patients had prior admission within 30 days, 22.2% had a recent history of antibiotics and 3.9% had long-term non-steroidal anti-inflammatory drug intake. Only one sample was positive for Clostridioides difficile toxin assay. Tissue Cytomegalovirus DNA-PCR positivity was noted in 57 patients (37.3%). Fifty-seven patients (37.3%) had steroid failure, 35 required medical rescue therapy and 30 (19.6%) required colectomy (eight after medical rescue therapy failure). Conclusion Despite antecedent risk factors for CDI, the overall prevalence of CDI in ASUC was low and the outcomes were determined by underlying disease severity.

Compensated Advanced Chronic Liver Disease in Nonalcoholic Fatty Liver Disease: Two-Step Strategy is Better than Baveno Criteria
Background Advanced fibrosis and cirrhosis (compensated advanced chronic liver disease [cACLD]) are clinically indistinguishable and increase risk of developing clinically significant portal hypertension. Baveno VII recommends using elastography to rule out and diagnose cACLD with liver stiffness measurement (LSM) cut-offs of 10/15 kPa. Methods In a retrospective analysis of 330 nonalcoholic fatty liver disease (NAFLD) patients, performance of the Baveno VII cut-offs for diagnosing cACLD was compared with newly suggested lower cut-offs (8/12 kPa). A model for detecting cACLD among those with LSM between 8 and 12 kPa was developed and compared with recently published models. Results Seventy (21.2%) of the 330 NAFLD patients had biopsy-proven cACLD. The Baveno VII cut-offs (10/15 kPa) had a lower sensitivity of 72.8% (60.9–82.8%) and a specificity of 93.4% (89.7–96.1%). Sensitivity and specificity of lower cut-offs (8/12 kPa) were 91.4% (82.3–96.8%) and 88.5% (83.9–92.1%), respectively. Modeling based on the presence of diabetes (odds ratio [OR] 3.625[1.161–11.320], p = 0.027) and serum aspartate aminotransferase (AST) levels (OR 1.636[1.098–2.436], p = 0.015) correctly identified 75.7% of patients with LSM between 8 and 12 kPa. Our model performed best with an area under receiver operator curve (AUROC) of 0.725 (95%CI 0.609–0.822), compared to Papatheodoridi (AUROC 0.626, CI 0.506–.736) and Zhou (AUROC 0.523, CI 0.403–0.640) models. A two-step strategy comprising application of lower LSM cut-offs followed by the predictive model correctly identified the presence of cACLD in 83% of the patients as compared to 75% by the Baveno VII cut-offs. Conclusion A two-step strategy employing lower LSM cut-offs and modeling based on diabetes and AST levels outperforms Baveno VII cut-offs for identifying cACLD in NAFLD patients.

Efficacy and tolerability of exclusive enteral nutrition in adult patients with complicated Crohn’s disease
Background/Aims: Exclusive enteral nutrition (EEN), an established modality for pediatric Crohn’s disease (CD) is seldomly utilized in adults. The present study reports the outcome of EEN in adult CD patients at a tertiary care hospital in India.Methods: This was a retrospective analysis of CD patients who received EEN as a sole modality/adjunct to other treatment. The primary and secondary outcomes changed in Crohn’s Disease Activity Index (CDAI), and clinical response (decline in CDAI > 70), respectively, at 4 and 8 weeks. Subgroup analysis evaluated response across different phenotypes, EEN formulations and prior treatment. Linear mixed effect model was created to assess the predictors of EEN response.Results: Thirty-one CD patients received EEN over median duration of 4 weeks (range, 2–6 weeks). CDAI showed a significant improvement post EEN at 4 (baseline 290 [260–320] vs. 240 [180–280], P= 0.001) and 8 weeks (baseline 290 [260–320] vs. 186 [160–240], P= 0.001), respectively. The cumulative clinical response rates at 4 and 8 weeks were 37.3% and 80.4% respectively. The clinical response rates at 8 weeks across B1 (n = 4), B2 (n = 18) and B3 (n = 9) phenotypes were 50%, 78.8% and 100% respectively (log-rank test, P= 0.093). The response rates at 8 weeks with polymeric (n = 8) and semi-elemental diet (n = 23) were 75% and 82.6%% respectively (log-rank test, P= 0.49). Baseline CDAI (odds ratio, 1.008; 95% confidence interval, 1.002–1.017; P= 0.046) predicted response to EEN.Conclusions: EEN was effective in inducing clinical response across different phenotypes of CD. Baseline disease activity remained the most important predictor of clinical response to EEN.

Successful Endoscopic Removal of a Transmural Internally Migrating Gossypiboma
An accidentally retained sponge inside the body of a patient (gossypiboma) is a rare and serious adverse event after a surgical procedure with serious medicolegal implications and complications. It is commonly associated with abdominal surgeries with cholecystectomy most commonly implicated. Whorl-like appearance or mottled translucencies and radiopaque marker on imaging is diagnostic. Transmural migration into a hollow viscous has been infrequently reported. The preferred approach for the removal of gossypiboma is surgery. However, in cases of complete transmural migration, endoscopic removal remains a viable option.

Surgical Management of Life Threatening Bleeding after Endoscopic Cystogastrostomy
Postprocedural bleeding is a rare but life threatening complication of endoscopic cystogastrostomy which may require surgical management in some patients. The presence of adhesions and inflammation due to antecedent acute pancreatitis, difficult location of the bleeding site and breach in the posterior wall of stomach pose significant challenges during the surgical management. Here we have described the surgical approach and technique that we used to manage three patients who required surgery for life threatening bleeding after endoscopic cystogastrostomy.

Development and validation of a new score for measuring post-operative complications
Assigning a numerical value to post-operative morbidity may improve its usefulness as an outcome measure. The recently developed Comprehensive Complication Index (CCI) is a step forward in this process but assigns an inappropriately high score to a combination of complications.
