RESUMO
INTRODUCTION: Endoscopic full-thickness resection (EFTR) is a promising technique that allows for a minimally invasive resection of mucosal and submucosal lesions in the gastrointestinal (GI) tract. The data regarding the efficacy and safety of performing EFTR of upper GI lesions using a full-thickness resection device (FTRD) is limited. Hence, we performed a systematic review and meta-analysis of the studies that evaluated this technique. METHODS: We performed a comprehensive systematic search of multiple electronic databases and conference proceedings that reported outcomes of EFTR using the FTRD system. The weighted pooled rates of technical success, complete (R0) resection, adverse events (AE), and residual or recurrent lesions were analyzed with 95% CI using the random effects model. RESULTS: Eight studies with a total of 139 patients who underwent EFTR of upper GI lesions were included in the study. The pooled, weighted rate of technical success was 88.2% (95% CI: 81.4-92.7%, I2 : 0). The R0 resection rate was 70.7% (95% CI: 62.5-77.8%, I2 : 0). Overall AE rates were 22.1% (95% CI: 15.8-30.1%, I2 : 0), however, most of the AEs were minor. Of the patients who had follow-up endoscopies, the residual and/or recurrent lesion rate was 6.1% (95% CI: 2.4-14.4%, I2 : 0). Heterogeneity in the analysis was low. CONCLUSIONS: EFTR using the FTRD seems to be effective and safe with acceptable R0 resection rates and low recurrence rates. Further prospective studies are required to validate our results and to compare various modalities of endoscopic resection with this single-step EFTR device.

BACKGROUND: Endoscopic therapy with endoscopic retrograde cholangiopancreatography is considered the first-line treatment in the management of post-cholecystectomy bile leak (PCBL). Currently, there is no consensus on the most effective endoscopic intervention for PCBL. Hence, we performed a systematic review and meta-analysis to compare the effectiveness and safety of the two interventional groups (biliary sphincterotomy [BS] alone vs. biliary stent ± BS) in management of PCBL. METHODS: We conducted a comprehensive search of multiple electronic databases and conference proceedings (from inception through January 2021). The primary outcome was to compare the pooled rate of clinical success between the 2 groups. The secondary outcome was to estimate the pooled rate of adverse events. RESULTS: The pooled rate of clinical success with BS alone (5 studies, 299 patients) was 88% (95% confidence interval (CI): 84-92%, I2: 0%) and for biliary stent ± BS (5 studies, 864 patients) was 97% (CI: 93-100%, I2: 79%). The rate of clinical success in biliary stent ± BS group was significantly higher than BS alone group (OR: 3.91 95% CI: 2.29-6.69, p < 0.001, I2: 13%). The rate of adverse events was numerically lower in biliary stent ± BS group compared to BS alone (3 studies; OR: 0.65 95% CI: 0.41-1.03, p = 0.07) without statistical significance. Low heterogeneity was noted in the analysis. CONCLUSIONS: Biliary stent ± BS is more effective in endoscopic management of PCBL compared to BS alone. This may be related to inter-endoscopist variation in completeness of sphincterotomy and post-sphincterotomy edema, which can influence the preferential trans-papillary flow of bile.

BACKGROUND & AIMS: Patients who chronically use alcohol, marijuana, or opioids, or suffer from post-traumatic stress disorder (PTSD), can be difficult to sedate with midazolam and fentanyl, and often are referred for monitored anesthesia care during endoscopy. Nurse-administered propofol continuous infusion sedation (NAPCIS), which confers the benefit of propofol-based sedation without the added expense of anesthesia, is effective and safe for sedation of healthy patients. We investigated whether NAPCIS also is effective for patients who are difficult to sedate. METHODS: We performed a retrospective study of patients who underwent upper endoscopy or colonoscopy with NAPCIS at a single center from January 2018 through April 2018. We reviewed records from patients who were heavy users of alcohol (n = 105), daily users of marijuana (n = 267) or opioids (n = 178), had a diagnosis of PTSD (n = 91), or were none of these (controls, n = 786). We compared mean fentanyl and propofol doses (adjusted for body weight), procedure and recovery times, procedure success rates, and adverse events. RESULTS: Compared with the controls, the marijuana group required higher mean adjusted sedative doses for colonoscopies (0.6 vs 0.4 mcg/kg fentanyl and 5.0 vs 4.7 mg/kg propofol; P ≤ .025 for both) and upper endoscopies (0.8 vs 0.3 mcg/kg fentanyl and 3.7 vs 3.2 mg/kg propofol; P ≤ .021 for both), the PTSD group required a higher dose of fentanyl for colonoscopies (0.6 vs 0.4 mcg/kg; P = .009), and the alcohol group required a higher dose of fentanyl for upper endoscopies (0.7 vs 0.3 mcg/kg; P < .001). Procedure success rates were high (95.1%-100%) and did not differ significantly between the difficult-to-sedate groups and controls; mean procedure times (7.0-9.0 minutes for upper endoscopies, 21.1-22.9 minutes for colonoscopies) and recovery times (22.5-29.6 minutes) also were similar among groups. Upper endoscopies were associated with lower sedative doses and shorter procedure and recovery times than colonoscopies. Sedation-related adverse events were rare in all groups (only 26 cases total), and there were no serious complications or deaths. CONCLUSIONS: NAPCIS seems to be a safe and effective means of providing sedation for endoscopy to patients who may be difficult to sedate owing to alcohol, marijuana, or opioid use, or PTSD.

BACKGROUND: Endoscopic therapy using radiofrequency ablation (RFA) is a recommended treatment for Barrett's esophagus with high-grade dysplasia (BE-HGD) without a visible lesion which is managed by resection. However, currently, there is no consensus on the management of BE with low-grade dysplasia (BE-LGD) - RFA versus endoscopic surveillance. Hence, we performed a systematic review and meta-analysis of these comparative studies to compare the risk of progression to HGD or esophageal adenocarcinoma (EAC) among patients with BE-LGD treated with RFA versus endoscopic surveillance. METHODS: The primary outcome was to compare the risk of progression to HGD or EAC among patients with BE-LGD treated with RFA versus endoscopic surveillance. RESULTS: Four comparative studies reporting a total of 543 patients with BE-LGD were included in the meta-analysis (234 in RFA and 309 in endoscopic surveillance). The progression of BE-LGD to either HGD or EAC was significantly lower in patients treated with RFA compared to endoscopic surveillance (OR: 0.17, 95% confidence interval [CI]: 0.04-0.65, p = 0.01). The progression to HGD alone was significantly lower in patients treated with RFA versus endoscopic surveillance (OR: 0.23, 95% CI: 0.08-0.61, p = 0.003). The progression to EAC alone was numerically lower in RFA than endoscopic surveillance without statistical significance (OR: 0.44, 95% CI: 0.17-1.16, p = 0.09). Moderate heterogeneity was noted in the analysis. CONCLUSIONS: Based on our meta-analysis, there was a significant reduction in the risk of progression to HGD or EAC among patients with BE-LGD treated with RFA compared with those undergoing endoscopic surveillance. Endoscopic eradication therapy with RFA should be the preferred management approach for BE-LGD.

Gastrointestinal stromal tumors (GISTs) are rare tumors of the gastrointestinal (GI) tract. Intermittent GI bleeding is the most common manifestation. Massive GI bleeding leading to syncopal episodes and hemorrhagic shock is a rare presentation of these tumors. Herein, we describe a case of a jejunal GIST presenting as massive bleeding.
RESUMO
Fenbendazole is an anthelmintic agent approved for veterinary applications. Even though it is not approved by the US Food and Drug Administration for human use, such use appears to be increasing due to the popularization of fenbendazole's potential anticancer effects by social media. We describe the first case of histologically confirmed severe drug-induced liver injury, hepatocellular pattern, associated with the self-administration of fenbendazole in a 67-year-old woman who presented with 2 weeks of jaundice. Liver function tests normalized in 3 months after the cessation of fenbendazole.
RESUMO
Viral hepatitis remains a significant global health problem. All forms of viral hepatitis A through E (A-E) can lead to acute symptomatic infection, while hepatitis B and C can lead to chronic infection associated with significant morbidity and mortality related to progression to cirrhosis, end-stage-liver disease, and liver cancer. Viral hepatitis occurs worldwide, though certain regions are disproportionately affected. We now, remarkably, have highly effective curative regimens for hepatitis C, and safe and tolerable medications to suppress hepatitis B activity, and to prevent liver damage and slow disease progression. We have effective vaccines for hepatitis A and B which provide long-lasting immunity, while improved sanitation and awareness can curb outbreaks of hepatitis A and E. However, more effective and available preventive and curative strategies are needed to achieve global eradication of viral hepatitis. This review provides an overview of the epidemiology, transmission, diagnosis, and clinical features of each viral hepatitis with a primary focus on current and future therapeutic and curative options.

BACKGROUND/AIMS: Multiple outbreaks of multidrug-resistant organisms have been reported worldwide due to contaminated duodenoscopes. In 2015, the United States Food and Drug Administration recommended the following supplemental enhanced surveillance and reprocessing techniques (ESRT) to improve duodenoscope disinfection: (1) microbiological culture, (2) ethylene oxide sterilization, (3) liquid chemical sterilant processing system, and (4) double high-level disinfection. A systematic review and meta-analysis was performed to assess the impact of ESRT on the contamination rates. METHODS: A thorough and systematic search was performed across several databases and conference proceedings from inception until January 2021, and all studies reporting the effectiveness of various ESRTs were identified. The pooled contamination rates of post-ESRT duodenoscopes were estimated using the random effects model. RESULTS: A total of seven studies using various ESRTs were incorporated in the analysis, which included a total of 9,084 post-ESRT duodenoscope cultures. The pooled contamination rate of the post-ESRT duodenoscope was 5% (95% confidence interval [CI]: 2.3%-10.8%, inconsistency index [I2]=97.97%). Pooled contamination rates for high-risk organisms were 0.8% (95% CI: 0.2%-2.7%, I2=94.96). CONCLUSION: While ESRT may improve the disinfection process, a post-ESRT contamination rate of 5% is not negligible. Ongoing efforts to mitigate the rate of contamination by improving disinfection techniques and innovations in duodenoscope design to improve safety are warranted.
RESUMO
BACKGROUND: It is not uncommon to see that a large proportion of patients with cirrhosis due to nonalcoholic steatohepatitis never had any prior evaluation or diagnosis of liver disease, and most of the times their first clinical presentation is decompensated cirrhosis. Acknowledging incidental finding of fatty liver on abdominal imaging and identifying patients at risk of having advanced liver fibrosis may help in preventing its progression to cirrhosis. AIM: We aimed to increase acknowledgement and improve evaluation of steatosis through radiology recommendation to consider hepatology referral, and to identify the predictors of hepatology referral and significant fibrosis. METHODS: We performed a retrospective study of 812 patients with hepatic steatosis tagged on ultrasound (US), over 18 months, at a single center. Patients with secondary causes of fatty liver were excluded from the study. We evaluated the yield of this intervention and factors correlated with hepatology referral and presence of significant fibrosis. RESULTS: Diagnosis of fatty liver was acknowledged for 69% of patients with tagged US, although only 29% were ultimately seen by hepatology. Patients who had US ordered by a primary care provider (PCP) were more likely to have hepatology evaluation (64.8% vs. 56.9%, P = 0.0183). Sixty-six percent of patients seen by hepatology had elevated alanine transaminase (ALT) compared to 52% not seen by hepatology (P < 0.0005). Among patients further evaluated, 53% underwent staging, and 18% had ≥stage 2 (F2) fibrosis. Type II diabetes correlated with significant to advanced fibrosis (43.5% vs. 21.4%, P = 0.0357), while ALT and Body Mass Index did not. CONCLUSIONS: Tagging US reports led to clinical acknowledgement of fatty liver in 7 of 10 patients, although fewer than 1 in 3 had further hepatology evaluation. Of those who underwent staging for incidentally noted steatosis, 18% had significant fibrosis, suggesting that we are failing to evaluate patients with potentially advanced liver disease. RELEVANCE FOR PATIENTS: Identifying incidental finding of fatty liver on US provides a unique opportunity in diagnosing liver fibrosis at an early stage and can help prevent its progression to cirrhosis. PCP should consider using noninvasive scoring systems on a regular basis to assess the risk of fibrosis in patients with fatty liver, and timely referral to hepatology should be provided in patients at high risk of having advanced fibrosis.
RESUMO
Mucosa-associated lymphoid tissue lymphoma (MALT lymphoma) accounts for approximately 5% of non-Hodgkin lymphomas, and the gastrointestinal (GI) tract is the most common site of involvement. The stomach and small intestine are the most common sites of involvement in the GI tract. Colonic MALT lymphoma is a rare condition that comprises only 2.5% of MALT lymphomas and less than 0.5% of all colon cancers. They usually present as colon mass or polyps. In this case report, we present a case of colonic MALT lymphoma diagnosed on random colon biopsies which is very rare.
RESUMO
Gastric adenosquamous carcinoma (GASC) is a rare variant of gastric cancer; the limited data available suggest that these tumors are more aggressive and have a worse outcome in comparison to gastric adenocarcinoma. Currently, the management of GASC is similar to adenocarcinoma. We report a case of GASC that progressed rapidly despite treatment.
RESUMO
Amyloidosis can affect multiple organs, and involvement of the heart is the most common cause of death. Signs and symptoms vary depending upon the organ system affected by amyloid. Liver involvement is often seen, but symptoms are usually mild and nonspecific in isolated hepatic amyloidosis. None of the laboratory markers and imaging is characteristic of this condition; therefore, diagnosis is often delayed. Tissue biopsy is required for definitive diagnosis. Herein, we report a case where the patient's symptoms had been attributed to alcohol-related cirrhosis; however, further workup ultimately led to a diagnosis of systemic amyloidosis with multi-organ involvement.
