Combination Topical Epinephrine and Non-steroidal Inflammatory Drugs in the Prevention of Post-ERCP Pancreatitis: A Systematic Review.

BACKGROUND: The utility of combination rectal NSAID and topical epinephrine (EI) or rectal NSAID and normal saline (SI) sprayed on duodenal papilla in the prevention of post-ERCP pancreatitis (PEP) has been studied but results have been conflicting. AIMS: To evaluate the benefit of using combination prophylaxis in preventing PEP. METHODS: A literature search was performed using Scopus, PubMed/MEDLINE, and Cochrane databases in May 2021. Randomized controlled trials (RCTs) involving adults patients who underwent ERCP and received EI versus SI were eligible for inclusion. The pooled effect was expressed as odds ratio (OR) to assess the rate of PEP, severity of PEP, and specific adverse events. The results were pooled using Reviewer Manager 5.4 software. RESULTS: Six RCTs involving 4016 patients were included in the final analysis. The EI group did not demonstrate any significant benefit over SI group in preventing PEP (OR = 1.00, 95% CI [0.68, 1.45], P = 0.98), irrespective of gender or the epinephrine concentration used. The tests for subgroup differences were not statistically significant with P-values of 0.66 and 0.28, respectively. The addition of topical epinephrine to rectal NSAID did not improve the rate of moderate to severe PEP (OR = 0.94, P = 0.86) or PEP in high-risk patients (OR = 1.14, 95%, P = 0.73). The rates of infection, including cholangitis and sepsis (OR = 0.63, P = 0.07), gastrointestinal bleeding (OR = 1.25, P = 0.56) and procedure-related death (OR = 0.71, P = 0.59) were similar between both groups. CONCLUSION: The addition of topical epinephrine did not demonstrate any benefit over rectal NSAID alone in preventing PEP or reducing other procedure-related adverse events.

Efficacy of Fecal Microbiota Transplantation in the Treatment of Active Ulcerative Colitis: A Systematic Review and Meta-Analysis of Double-Blind Randomized Controlled Trials.

BACKGROUND: Fecal microbiota transplantation (FMT) has been investigated as a treatment option for patients with inflammatory bowel disease with controversial results.We sought to perform a systematic review and meta-analysis to evaluate the benefit of FMT in patients with ulcerative colitis. METHODS: Double-blind randomized controlled trials (RCTs) including adult patients with active ulcerative colitis who received either FMT or placebo were eligible for inclusion. Outcomes of interest included the rate of combined clinical and endoscopic remission, endoscopic remission or response, clinical remission or response, and specific adverse events. The results were pooled together using Reviewer Manager 5.4 software. Publication bias was assessed using the Egger's test. RESULTS: Six RCTs involving 324 patients were included. Our findings demonstrate that compared with placebo, FMT has significant benefit in inducing combined clinical and endoscopic remission (odds ratio, 4.11; 95% confidence interval, 2.19-7.72; P < .0001). Subgroup analyses of influencing factors showed no differences between pooled or single stool donors (P = .71), fresh or frozen FMT (P = .35), and different routes or frequencies of delivery (P = .80 and .48, respectively). Pre-FMT antibiotics, bowel lavage, concomitant biologic therapy, and topical rectal therapy did not affect combined remission rates (P values of .47, .38, .28, and .40, respectively). Clinical remission or response and endoscopic remission or response were significantly higher in patients who received FMT compared with placebo (P < .05) without any differences in serious or specific adverse events. CONCLUSIONS: FMT demonstrated a clinical and endoscopic benefit in the short-term treatment of active ulcerative colitis, with a comparable safety profile to placebo. Future RCTs are required to standardize study protocols and examine data on maintenance therapy.

Our systematic review of double-blind randomized controlled trials demonstrates that fecal microbiota transplantation is effective in inducing short-term clinical and endoscopic remission in adult patients with active ulcerative colitis and with a similar safety profile as compared with placebo.

Effect of computer-aided colonoscopy on adenoma miss rates and polyp detection: A systematic review and meta-analysis.

BACKGROUND AND AIM: Multiple computer-aided techniques utilizing artificial intelligence (AI) have been created to improve the detection of polyps during colonoscopy and thereby reduce the incidence of colorectal cancer. While adenoma detection rates (ADR) and polyp detection rates (PDR) are important colonoscopy quality indicators, adenoma miss rates (AMR) may better quantify missed lesions, which can ultimately lead to interval colorectal cancer. The purpose of this systematic review and meta-analysis was to determine the efficacy of computer-aided colonoscopy (CAC) with respect to AMR, ADR, and PDR in randomized controlled trials. METHODS: A comprehensive, systematic literature search was performed across multiple databases in September of 2022 to identify randomized, controlled trials that compared CAC with traditional colonoscopy. Primary outcomes were AMR, ADR, and PDR. RESULTS: Fourteen studies totaling 10 928 patients were included in the final analysis. There was a 65% reduction in the adenoma miss rate with CAC (OR, 0.35; 95% CI, 0.25-0.49, P < 0.001, I2  = 50%). There was a 78% reduction in the sessile serrated lesion miss rate with CAC (OR, 0.22; 95% CI, 0.08-0.65, P < 0.01, I2  = 0%). There was a 52% increase in ADR in the CAC group compared with the control group (OR, 1.52; 95% CI, 1.39-1.67, P = 0.04, I2  = 47%). There was 93% increase in the number of adenomas > 10 mm detected per colonoscopy with CAC (OR 1.93; 95% CI, 1.18-3.16, P < 0.01, I2  = 0%). CONCLUSIONS: The results of the present study demonstrate the promise of CAC in improving AMR, ADR, PDR across a spectrum of size and morphological lesion characteristics.

Endoscopic ultrasound-guided portal pressure gradient with liver biopsy: 6 years of endo-hepatology in practice.

BACKGROUND AND AIM: The portal pressure gradient (PPG) is a useful predictor of portal hypertension (PH) related complications. We previously showed the feasibility and safety of endoscopic ultrasound guided PPG measurement (EUS-PPG). Now EUS-guided liver biopsy (EUS-bx) has been shown to be a safe and effective alternative to percutaneous or Interventional Radiology-guided liver biopsy for the diagnosis of chronic liver disease (CLD). We aimed to evaluate the correlation between PPG and clinical markers of PH, and assess the feasibility and safety of concomitant, single session EUS-PPG and EUS-bx. METHODS: This was a retrospective study of patients undergoing EUS-PPG for CLD at a single tertiary endoscopy center between February 2014 and March 2020. EUS-PPG was performed using a 25-gauge needle and compact manometer. Data analysis was performed with SAS version 9.4. RESULTS: Eighty-three patients underwent EUS-PPG with 100% technical success. The mean PPG was 7.06 mmHg (SD 6.09, range 0-27.3). PPG was higher in patients with (vs without) clinical features of cirrhosis (9.46 vs 3.61 mmHg, P < 0.0001), esophageal or gastric varices (13.88 vs 4.34 mmHg, P < 0.0001), and thrombocytopenia (9.25 vs 4.71 mmHg, P = 0.0022). In the 71 patients (85.5%) who underwent EUS-bx, 70 (98.6%) specimens were deemed adequate by the pathologist for histologic diagnosis. There were no early or late major adverse events. CONCLUSION: EUS-PPG correlates well with clinical markers of PH. EUS-bx can be performed safely during the same session as EUS-PPG, providing a comprehensive endoscopic evaluation of the patient with CLD.

Metastatic Testicular Embryonal Carcinoma Presenting as Gastrointestinal Hemorrhage.

Testicular cancer is the most common malignancy in men aged 20-35 years, usually presenting with painless scrotal swelling. Metastases, should they occur, frequently involve retroperitoneal lymph nodes, which drain the testes. Gastrointestinal (GI) metastases are rare, and metastatic disease may not initially be considered in a young man presenting with GI hemorrhage. This case demonstrates the importance of evaluating for a primary underlying malignancy, especially if other causes of GI hemorrhage have been ruled out. Testicular primary should additionally be considered in men because early intervention may often lead to improved clinical outcomes.

Illness cognition and health anxiety in parents of children with cancer.

Purpose: Health anxiety is a clinical entity characterized by a pathological fear of illness. Illness cognition refers to persistent positive or negative thoughts an individual has towards illness. Evidence has shown that patients with chronic conditions who possess negative illness cognitions experience greater social, emotional, and physical difficulties than patients with positive illness cognitions. This study aims to measure the prevalence of health anxiety in a population of parents of children with cancer, and investigate the association between positive and negative illness cognitions and health anxiety. Methods: We interviewed 105 parents of children with cancer and administered Arabic versions of the Illness Cognition Questionnaire - Parent Version and the Short Health Anxiety Inventory. Results: The mean parental age was 37.7 years with the majority of participants being mothers (78.1%) and married (94.3%) and with 35.2% having completed university education. The average age of the child with cancer was 8.4 years, with the largest proportion of children suffering from leukemia. The prevalence of health anxiety among parents of children with cancer was 21%. The following two dimensions of illness cognition were significantly associated with health anxiety: Helplessness (B = 0.222, p = 0.021) and lower Acceptance (B = -0.242, p = 0.008). Other variables associated with health anxiety were perceived inadequate income (B = -0.238, p = 0.021) and personal illness or illness of a family member/close friend (B = 0.251, p = 0.013). Conclusions: Parents of children with cancer may experience health anxiety. Predictors of health anxiety include feelings of helplessness, lower acceptance, inadequate income, and extended family illnesses.
