ABSTRACT
Methotrexate is commonly used to treat autoimmune conditions and malignancy. Peptic ulcer disease is a sparsely documented side effect of methotrexate. A 70-year-old female patient with rheumatoid arthritis on methotrexate presented with generalized fatigue and was found to be anemic. Endoscopy revealed gastric ulcers, the etiology of which was attributed to methotrexate use after careful exclusion of other possible causes. Cessation of methotrexate has been reported in the literature as vital to the healing of ulcers. Proton pump inhibitors or histamine 2 receptor (H2R) blockers may also be used as treatment; however, methotrexate should be discontinued before initiation of proton pump inhibitors, which can hinder the metabolism of methotrexate and can, in turn, lead to a worsening of the peptic ulcer disease.
ABSTRACT
The rate of alcoholic hepatitis (AH) has risen in recent years. AH can cause as much as 40-50% mortality in severe cases. Successful abstinence has been the only therapy associated with long-term survival in patients with AH. Thus, it is crucial to be able to identify at-risk individuals in order to implement preventative measures. From the patient database, adult patients (age 18 and above) with AH were identified using the ICD-10 classification from November 2017 to October 2019. Liver biopsies are not routinely performed at our institution. Therefore, patients were diagnosed with AH based on clinical parameters and were divided into "probable" and "possible" AH. Logistic regression analysis was performed to determine risk factors associated with AH. A sub-analysis was performed to determine variables associated with mortality in AH patients. Among the 192 patients with alcohol dependence, there were 100 patients with AH and 92 patients without AH. The mean age was 49.3 years in the AH cohort, compared to 54.5 years in the non-AH cohort. Binge drinking (OR 2.698; 95% CI 1.079, 6.745; p = 0.03), heavy drinking (OR 3.169; 95% CI 1.348, 7.452; p = 0.01), and the presence of cirrhosis (OR 3.392; 95% CI 1.306, 8.811; p = 0.01) were identified as characteristics more commonly found in the AH cohort. Further, a higher inpatient mortality was seen in those with a probable AH diagnosis (OR 6.79; 95% CI 1.38, 44.9; p = 0.03) and hypertension (OR 6.51; 95% CI 9.49, 35.7; p = 0.02). A higher incidence of mortality was also noted among the non-Caucasian race (OR 2.72; 95% CI 4.92; 22.3; p = 0.29). A higher mortality rate despite a lower incidence of alcohol use among non-Caucasian patients may indicate healthcare disparities.

Gastric siderosis is the deposition of excess amount of iron from oral ferrous sulfate supplements to the gastric mucosa. It is an often overlooked entity in the literature and can be related to symptoms such as dyspepsia, nausea, and melena through mucosal injury. Different etiologies of gastric siderosis display distinct histopathological patterns. Pattern B, which is most commonly associated with oral iron supplements, is seen when iron is deposited in the extracellular space of the lamina propria. It is crucial to consider gastric siderosis as a potential diagnosis in symptomatic patients and to evaluate the necessity of oral ferrous sulfate supplements.
ABSTRACT
Background and Aims: Due to increasing knowledge of the "gut-liver axis", there has been growing interest regarding the use of fecal microbiota transplant in the management of chronic liver disease. There are limited data available and current guidelines are mostly based on expert opinions. We aim to perform the first systematic review investigating safety and efficacy of fecal microbiota transplant particularly among high-risk decompensated cirrhosis patient populations. Methods: Literature search was performed using variations of the keywords "fecal microbiota transplant" and "cirrhosis" on PubMed/Medline from inception to 3 October 2021. The resulting 116 articles were independently screened by two authors. In total, 5 qualifying studies, including 2 randomized control trials and 3 retrospective case series, were found to meet established eligibility criteria and have adequate quality of evidence to be included in this review. Results: Of the total 58 qualifying patients, there were 2 deaths post fecal microbiota transplant, 1 of which could not rule out being related (1.7%). Among the remaining 56 participants, 8 serious adverse events were reported, of which 2 could not rule out being related (3.6%). The success rate of fecal microbiota transplantation in treating recurrent Clostridioides difficile infection among patients with decompensated cirrhosis was 77.8%. The success rate when used as investigational treatment for hepatic encephalopathy was 86.7%, with multiple studies reporting clinically significant improvement in encephalopathy testing scores. Conclusions: We found a marginally higher rate of deaths and serious adverse events from fecal microbiota transplant in our patient population compared with the average immunocompetent population, where it was previously found to have 0 deaths and SAE rate of 2.83%. The efficacy when used for recurrent C.difficile infection was 77.8% and 87% in the decompensated cirrhotic and general populations, respectively. Studies on efficacy in novel treatment of hepatic encephalopathy have been promising. This study concludes that fecal microbiota transplant use in decompensated cirrhosis patients should be used with caution and preferably be limited to research purposes until better data are available.
ABSTRACT
The microbiome of the human gut and liver coexists by influencing the health and disease state of each system. Fecal microbiota transplantation (FMT) has recently emerged as a potential treatment for conditions associated with cirrhosis, such as hepatic encephalopathy and recurrent/refractory Clostridioides difficile infection (rCDI). We have conducted a systematic review of the safety and efficacy of FMT in treating hepatic encephalopathy and rCDI. A literature search was performed using variations of the keywords "fecal microbiota transplant" and "cirrhosis" on PubMed/MEDLINE from inception to October 3, 2021. The resulting 116 articles were independently reviewed by two authors. Eight qualifying studies were included in the systematic review. A total of 127 cirrhotic patients received FMT. Hepatic encephalopathy was evaluated by cognitive tests, such as the Psychometric Hepatic Encephalopathy Score (PHES) and EncephalApp Stroop test. Not only was there an improvement in the cognitive performance in the FMT cohort, but the improvement was also maintained throughout long-term follow-up. In the treatment of rCDI, the FMT success rate is similar between cirrhotic patients and the general population, although more than one dose may be needed in the former. The rate of serious adverse events and adverse events in the cirrhotic cohort was slightly higher than that in the general population but was low overall. We found evidence that supports the therapeutic potential and safety profile of FMT to treat hepatic encephalopathy and rCDI in cirrhotic patients. Further research will be beneficial to better understand the role of FMT in cirrhosis.
ABSTRACT
Background and Objectives: Needle-based confocal laser endomicroscopy (nCLE) is a procedure in which an AQ-Flex nCLE mini-probe is passed through an EUS-FNA needle into a pancreatic lesion to enable subsurface in vivo tissue analysis. In this study, we conducted a systematic review and meta-analysis of nCLE for the diagnosis of pancreatic lesions. Materials and Methods: We conducted a comprehensive search of several databases and conference proceedings, including PubMed, EMBASE, Google-Scholar, MEDLINE, SCOPUS, and Web of Science databases (earliest inception to March 2020). The primary outcomes assessed the pooled rate of diagnostic accuracy for nCLE and the secondary outcomes assessed the pooled rate of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and adverse events (AE) of nCLE to diagnose premalignant/malignant pancreatic lesions. Results: Eleven studies on 443 patients were included in our analysis. The pooled rate of diagnostic accuracy of EUS nCLE was 83% (95 confidence interval [CI] = 79-87; I 2 = 0). The pooled rate of sensitivity, specificity, PPV and NPV of EUS nCLE was 85.29% (95% CI = 76.9-93.68; I 2 = 85%), 90.49% (95% CI = 82.24-98.74; I 2 = 64%), 94.15% (95% CI = 88.55-99.76; I 2 = 68%), and 73.44% (95% CI = 60.16-86.72; I 2 = 93%), respectively. The total AE rate was 5.41% (±5.92) with postprocedure pancreatitis being the most common AE at 2.28% (±3.73). Conclusion: In summary, this study highlights the rate of diagnostic accuracy, sensitivity, specificity, and PPV for distinguishing premalignant/malignant lesions. Pancreatic lesions need to be further defined with more validation studies to characterize CLE diagnosis criteria and to evaluate its use as an adjunct to EUS-FNA.
ABSTRACT
Transarterial angiographic embolization is a highly effective, safe treatment for non-variceal upper gastrointestinal bleeding refractory to endoscopic intervention. However, intraluminal coil migration is a possible complication. Coil migration, while usually a self-limiting process, can lead to significant rebleeding. In our case, a patient presented with a life-threatening duodenal ulcer hemorrhage, likely precipitated by intraluminal endovascular coil migration after a recent gastro-duodenal artery embolization. He was successfully managed without endoscopic coil removal and had no additional gastrointestinal bleeding. It is important for endoscopists to be aware of this complication and weigh the risks and benefits of coil removal.
ABSTRACT
BACKGROUND/AIM: Acute pancreatitis (AP) is a commonly encountered emergency where early identification of complicated cases is important. Inflammatory markers like lymphocyte to monocyte ratio (LMR) and neutrophil to lymphocyte ratio (NLR) are simple and readily available markers. In this study, we evaluated the utility of these markers in the early identification of patients with complicated AP. PATIENTS AND METHODS: All patients with a diagnosis of AP admitted to the University Medical Center in Las Vegas/Nevada between August 2015 and September 2018 were identified using ICD-10 codes. Medical records were reviewed retrospectively. Epidemiological measures and their associated confidence intervals were calculated using MedCalc (v. 18). RESULTS: The LMR showed a significant difference between groups, with the non-complicated cases consistently higher than the complicated cases but without significant temporal differences. The NLR showed a significant difference with a significant temporal relation. Using the bound of the 95% confidence interval separating the two groups, LMR <2 was found to be associated with a complicated case and NLR >10.5 was suggestive of a complicated case. High specificity (85-92%) with low sensitivity (23-69%) was noted; hence, these cut points were very good at discerning non-complicated cases. CONCLUSION: Our data show persistently low LMR that is associated with severe AP and a value of <2.0 can be used clinically to predict severe AP on admission. It also shows that elevated NLR is associated with complicated AP and prolonged hospital stay with a value >10.5 that can be used to predict severe complicated AP and to monitor response to treatment over time.
ABSTRACT
PURPOSE OF REVIEW: Chronic pancreatitis in the advanced stages leads to significant health care utilization because of the associated complications. Early-stage diagnosis could prevent the development of these complications by appropriate management. In this article, we reviewed the recent evidence pertaining to the diagnosis and management of early chronic pancreatitis (ECP). RECENT FINDINGS: The working group for the International Consensus Guidelines for Chronic Pancreatitis has published consensus-based statements to streamline the diagnosis of ECP. There is no international consensus on the definition and diagnosis of ECP. The Revised Japanese Diagnostic Criteria for ECP based on clinical features and endoscopic ultrasound findings have been proposed. Large prospective cohort studies are needed to develop and validate internationally acceptable diagnostic criteria. ECP is recognized as a distinct stage in the development and progression of CP. Consensus-based definitions and diagnostic criteria need to be developed.

BACKGROUND: The development of anti-drug antibodies (ADA) to tumor necrosis factor (TNF-α) inhibitors is a significant result contributing to the loss of clinical response in inflammatory bowel disease (IBD). AIMS: We performed a systematic review and meta-analysis to assess whether the addition of immunomodulators to TNF-α inhibitors lead to reversal of antibody formation in TNF-α inhibitor-treated IBD patients. METHODS: We conducted a comprehensive search of electronic databases from inception through October 2018 in order to identify specific studies describing clinical response in IBD patients following the addition of immunomodulators (methotrexate or thiopurines) to TNF-α inhibitors. Clinical response was expressed as an improvement of symptoms, with a noted decrease or complete elimination of ADA against TNF-α inhibitors. The meta-analysis was performed using the DerSimonian and Laird random-effect model. RESULTS: Four studies were included in our final meta-analysis, which reported outcomes in 72 patients receiving TNF-α inhibitors. Forty-nine of the seventy-two (68%) patients received either methotrexate (19) or thiopurines (30). The average follow up period was 13.5 months. The overall pooled clinical response was 73.86% (95% confidence interval [CI] = 47.36-94.38, I2 = 60.77%). CONCLUSION: In our meta-analysis, addition of immunomodulators to TNF-α inhibitors was shown to restore the clinical response in 74% of the patients by either decreasing or completely eliminating anti-drug antibody levels. Further long-term multicenter studies are needed to validate these findings.

ERCP is the current procedure of choice for patients with jaundice caused by biliary obstruction. EUS-guided biliary drainage (EUS-BD) has emerged as an alternative to ERCP in patients requiring biliary drainage. The aim of the study was to conduct a systematic review and meta-analysis to report the overall efficacy and safety of EUS-BD. We conducted a comprehensive search of several databases including PubMed, EMBASE, Web of Science, Google Scholar, and LILACS databases (earliest inception to June 2018) to identify studies that reported EUS-BD in patients. The primary outcome was to look at the technical and clinical success of the procedure. The secondary analysis focused on calculating the pooled rate of re-interventions and all adverse-events, along with the commonly reported adverse-event subtypes. Twenty-three studies reporting on 1437 patients were identified undergoing 1444 procedures. Majority of the patient population were male (53.86%), with an average age of 67.22 years. The pooled technical success rates and clinical success rates were 91.5% (95% confidence interval [CI]: 87.7-94.2, I[2] = 76.5) and 87% (95% CI: 82.3-90.6, I[2] = 72.4), respectively. The total adverse event rates were 17.9% (95% CI: 14.3-22.2, I[2] = 69.1). Subgroup analysis of three major individual adverse events was bile leak: 4.1% (2.7-6.2, I[2] = 46.7), stent migration: 3.9% (2.5-6.2, I[2] = 43.5), and infection: 3.8% (2.8-5.1, I[2] = 0) Substantial heterogeneity was noted in the analysis. EUS-BD has high technical and clinical success rate and hence a very effective procedure. Concerns about publication bias exist. Careful consideration should be given to the adverse events and weighing the risks and benefits of the alternative nonsurgical/surgical approaches.
ABSTRACT
Background and study aims Endoscopic ultrasound-directed transgastric ERCP (EDGE) is a new endoscopic procedure to perform ERCP in Roux-en-y gastric bypass (RYGB) patients. The aim of this study was to conduct a systematic review and meta-analysis to evaluate technical success, clinical success and adverse effects of EDGE and compare it to laparoscopic ERCP (LA-ERCP) and balloon ERCP (BE-ERCP). Patients and methods We conducted a comprehensive search of several databases and conference proceedings including PubMed, EMBASE, Google-Scholar, LILACS, SCOPUS, and Web of Science databases to identify studies reporting on EDGE, LA-ERCP, and BE-ERCP. The primary outcome was to evaluate technical and clinical success of all three procedures and the secondary analysis focused on calculating the pooled rate of all adverse events (AEs), along with the commonly reported AE subtypes. Results Twenty-four studies on 1268 patients were included in our analysis with the majority of the population being males with mean age 53.72 years. Pooled rates of technical and clinical success with EDGE wer 95.5â% and 95.9â%, with LA-ERCP were 95.3â% and 92.9â% and were BE-ERCP were 71.4â% and 58.7â%, respectively. Pooled rates of all AEs with EDGE were 21.9â%, with LA-ERCP 17.4â% and with BE-ERCP 8.4â%. Stent migration was the most common AE with EDGE with 13.3â% followed by bleeding with 6.6â%. Conclusion Our meta-analysis demonstrated that the technical and clinical success of EDGE procedure is better than BE-ERCP and comparable to that of LA-ERCP in RYGB patients. EDGE also has a similar safety profile as compared to LA-ERCP but has higher AE rate as compared to BE-ERCP.
ABSTRACT
BACKGROUND AND AIMS: Fecal microbiota transplantation (FMT) is used in recurrent Clostridioides difficile infections. However, protocols are facility dependent, and one variable is whether pre-procedural proton pump inhibitors (PPIs) are given. In theory, PPIs reduce acidity and protect the transplanted microbiome for the most potent dose. We conducted a systematic review to study the effect of PPIs on FMT delivered by upper gastrointestinal (GI) routes. METHODS: We searched Pubmed/Medline, Cochrane Library, Embase, Scopus, and Web of Science through December 16, 2018 using variations of keywords "fecal microbiota transplant" and "Clostridium difficile infection." Two authors independently reviewed 4210 results and found 11 qualifying studies with data on upper GI FMT, use of PPIs, and the rate of treatment failure at follow-up. RESULTS: Of 233 included patients, treatment failure occurred in 20.6% of those with use of PPIs versus 22.6% in the group without (relative risk 0.91; confidence interval 0.56-1.50). Limitations include the lack of studies directly comparing outcomes based on use of PPIs and inability to control for possible confounders such as chronic PPI use, amount of stool transplanted, and pre-FMT antibiotics. CONCLUSIONS: We did not find evidence supporting a clinically significant benefit from routine use of PPIs in FMT protocol. It is possible that the theoretical benefit from improved survival of transplanted microbiota is offset by negative effects on the microbiome. We suggest that routine use of PPIs in upper GI FMT be reconsidered. Further investigation is needed to optimize protocols for safety and efficacy.

BACKGROUND: Liver disease in patients with HIV is common and typically has complex and multifactorial presentations that represent a major cause of morbidity and mortality. Autoimmune hepatitis (AIH) is rarely reported in patient with HIV and the disease course and clinical outcomes for treatment have not been well characterized. We are aiming to determine the patient characteristics, disease prevalence, and treatment outcomes from published articles of patients with HIV and AIH. METHOD: A systematic search of PubMed, Web of Science, and Google Scholar through February 20, 2019 identified 15 studies that reported the outcomes of AIH in patients with HIV. Because of the small sample sizes and skewed distributions, resampling tests of mean differences using permutation distributions (MAXnâ=â10,000 permutations) were utilized; analyses were performed using R (v. 3.5.1). Categorical differences were calculated using Fisher exact test for odds ratio = 1 (equal odds), and Cramer V was calculated for effect size; analyses were completed in SPSS (v. 25). RESULTS: By reviewing 15 studies reporting a total of 35 patients with AIH and HIV, male patients were found to have significantly higher aspartate transaminase and alanine transaminase levels at time of diagnosis. No other significant findings identified. The CD4 count and viral load did not show significant correlation with AIH diagnosis or its prognosis. All patients but one who presented with severe immune deficiency and responded to highly active anti-retroviral therapy received immunosuppressive treatment without side effects and achieved remission except 2 lost to follow-up and 3 expired. CONCLUSION: Although rare, but AIH can develop in patients with HIV and physicians should consider it in the differential diagnosis for HIV patients presented with abnormal liver function tests, especially after excluding hepatitis C virus and drug-induced liver injury.Patients with immune deficiency disorders who present with AIH can be treated safely with steroid either as monotherapy or in combination with another immune suppressant therapy.

INTRODUCTION: Autoimmune hepatitis (AIH) is a cause of chronic liver disease. It is usually suspected based on clinical presentation and laboratory findings, but the diagnosis relies on the presence of specific autoantibodies and characteristic histology. Other unexplained findings should always prompt investigation for coexisting syndromes. CASE PRESENTATION: The patient is a 60-year-old Hispanic female with a history of mild asthma presented with exertional and pleuritic chest pain with weight loss, arthralgia, subjective fever, and night sweats for the last 3 months. Given the nonspecific nature of the presentation, further workup was pursued. Laboratory results indicated pancytopenia, elevated INR, and positive autoimmune panel including ANA, anti-chromatin, anti-histone, and rheumatoid factor as well as abnormal C3 and C4. Subsequent liver biopsy with interface hepatitis lead to a diagnosis of AIH with concurrent systemic lupus erythematosus suspected. CONCLUSION: The diagnostic work up for AIH is multimodal and aims to differentiate other etiologies such as congestive hepatopathy, iron overload, viral hepatitis, and other autoimmune liver diseases. In this particular case, unusual clinical and laboratory findings led to diagnosis of the overlap syndrome. Treatment for both was necessary to prevent further progression of disease.

AIM: To investigate indications and outcomes of endoscopic retrograde cholangiopancreatography (ERCP) in cirrhotics, especially adverse events. Patients with cirrhosis undergoing ERCP are believed to have increased risk. However, there is a paucity of literature describing the indications and outcomes of ERCP procedures in patients with cirrhosis, especially focusing on adverse events. METHODS: We performed a systematic appraisal of major literature databases, including PubMed and EMBASE, with a manual search of literature from their inception until April 2017. RESULTS: A total of 6,505 patients from 15 studies were analyzed (male ratio 59%, mean age 59 years), 11% with alcoholic and 89% with non-alcoholic cirrhosis, with 56.2% Child-Pugh class A, and 43.8% class B or C. Indications for ERCP included choledocholithiasis 60.9%, biliary strictures 26.2%, gallstone pancreatitis 21.1% and cholangitis 15.5%. Types of interventions included endoscopic sphincterotomy 52.7%, biliary stenting 16.7% and biliary dilation 4.6%. Individual adverse events included hemorrhage in 4.58% (95%CI: 2.77-6.75%, I 2 = 85.9%), post-ERCP pancreatitis (PEP) in 3.68% (95%CI: 1.83-6.00%, I 2 = 89.5%), cholangitis in 1.93% (95%CI: 0.63-3.71%, I 2 = 87.1%) and perforation in 0.00% (95%CI: 0.00-0.23%, I 2 = 37.8%). Six studies were used for comparison of ERCP-related complications in cirrhosis vs non-cirrhosis, which showed higher overall rates of complications in cirrhosis patients with pooled OR of 1.63 (95%CI: 1.27-2.09, I 2 = 65%): higher rates of hemorrhage with OR of 2.05 (95%CI: 1.62-2.58, I 2 = 2.1%) and PEP with OR of 1.33 (95%CI: 1.04-1.70, I 2=65%), but similar cholangitis rates with OR of 1.23 (95%CI: 0.67-2.26, I 2 = 44.3%). CONCLUSION: There is an overall higher rate of adverse events related to ERCP in patients with cirrhosis, especially hemorrhage and PEP. A thorough risk/benefit assessment should be performed prior to undertaking ERCP in patients with cirrhosis.
ABSTRACT
Background While endoscopic retrograde cholangiopancreatography (ERCP) is usually performed in the prone position, some studies have advocated for ERCP in the supine position. Studies comparing the technical success and safety outcomes have shown variable results. We performed a systematic review and meta-analysis of studies reporting the comparison between the two positions for ERCP outcomes. Methods We conducted a search of electronic databases and conference proceedings including PubMed, EMBASE, and Web of Science databases (from inception through October 2016) to identify studies that reported the comparison of technical success and safety outcomes between supine and prone ERCP. The primary outcome was to estimate the pooled rates of technical success. The secondary outcome was to estimate the risks of complications, such as cardiopulmonary and post-ERCP pancreatitis (PEP). Results Six studies reporting on 309 supine and 1415 prone ERCPs were identified. The pooled technical success rates for completion of ERCP in supine and prone positions were 89.1â% (95â%CIâ=â80.9â-â94.0) and 95.6â% (95â%CIâ=â91.5â-â97.7), respectively. The pooled rates for complications (cardiopulmonary and PEP) in the supine position were 37.5â% (95â%CIâ=â19.1â-â60.3) and 3.5â% (95â%CIâ=â1.6â-â7.3), respectively. The pooled rates for complications (cardiopulmonary and PEP) in the prone position were 41.0â% (95â%CIâ=â20.9â-â64.8) and 3.9â% (95â%CIâ=â2.4â-â6.4), respectively. The mean time required for the procedure was 30 minutes and 29.8 minutes for supine and prone positions, respectively. Substantial heterogeneity was noted in the analysis. Conclusion Prone ERCPs have a higher technical success rate with a slightly lower mean duration but a higher number of adverse events. The decision with regard to patient position should be made after evaluating the overall clinical scenario.
ABSTRACT
BACKGROUND: To evaluate roles of intraoperative endoscopy (IOE) in management of severe obscure GI bleeding (OGIB) before vs. after introduction of video capsule endoscopy (VCE) and deep enteroscopy (DE). METHODS: We retrospectively reviewed prospectively collected data of patients undergoing IOE for severe OGIB in a tertiary referral center. RESULTS: 52 patients had laparotomy/IOE for OGIB, 11 pre and 41 post VCE/DE eras. In the pre VCE/DE era, 36.4% (4/11) had preoperative presumptive diagnoses while in the post VCE/DE era presumptive diagnoses were made in 48.8% (20/41) (p = 0.18). Preoperative evaluation led to correct diagnoses in 18.2% (2/11) in the pre and 51.2% (21/41) in the post VCE/DE era (p = 0.09). Vascular lesions and ulcers were the most common diagnoses, but rebleeding was common. No rebleeding was found among patients with tumors, Meckel's diverticulum, and aortoenteric fistula. CONCLUSIONS: Presumptive diagnoses in the post VCE/DE era were usually accurate. If VCE or DE are negative, the probability of negative IOE is high. Patients with tumors and Meckel's diverticulum were the best candidates for IOE.

BACKGROUND & AIMS: For 4 decades, stigmata of recent hemorrhage in patients with nonvariceal lesions have been used for risk stratification and endoscopic hemostasis. The arterial blood flow that underlies the stigmata rarely is monitored, but can be used to determine risk for rebleeding. We performed a randomized controlled trial to determine whether Doppler endoscopic probe monitoring of blood flow improves risk stratification and outcomes in patients with severe nonvariceal upper gastrointestinal hemorrhage. METHODS: In a single-blind study performed at 2 referral centers we assigned 148 patients with severe nonvariceal upper gastrointestinal bleeding (125 with ulcers, 19 with Dieulafoy's lesions, and 4 with Mallory Weiss tears) to groups that underwent standard, visually guided endoscopic hemostasis (control, n = 76), or endoscopic hemostasis assisted by Doppler monitoring of blood flow under the stigmata (n = 72). The primary outcome was the rate of rebleeding after 30 days; secondary outcomes were complications, death, and need for transfusions, surgery, or angiography. RESULTS: There was a significant difference in the rates of lesion rebleeding within 30 days of endoscopic hemostasis in the control group (26.3%) vs the Doppler group (11.1%) (P = .0214). The odds ratio for rebleeding with Doppler monitoring was 0.35 (95% confidence interval, 0.143-0.8565) and the number needed to treat was 7. CONCLUSIONS: In a randomized controlled trial of patients with severe upper gastrointestinal hemorrhage from ulcers or other lesions, Doppler probe guided endoscopic hemostasis significantly reduced 30-day rates of rebleeding compared with standard, visually guided hemostasis. Guidelines for nonvariceal gastrointestinal bleeding should incorporate these results. ClinicalTrials.gov no: NCT00732212 (CLIN-013-07F).

BACKGROUND: The sites of origin, causes and outcomes of severe hematochezia have not been compared between cirrhotics and non-cirrhotics. In cirrhotics versus non-cirrhotics presenting with severe hematochezia, we aimed at (1) identifying the site and etiology of gastro-intestinal bleeding and independent predictors of bleeding from the upper gastrointestinal tract versus small bowel or the colon, (2) comparing 30-day clinical outcomes, and (3) proposing an algorithm for management of severe hematochezia. METHODS: In this cohort study from two university-based medical centers, 860 consecutive patients with severe hematochezia admitted from 1995 to 2011 were prospectively enrolled with 160 (18.6 %) cirrhotics. We studied (a) general clinical and laboratory characteristics of cirrhotics versus non-cirrhotics, (b) predictors of bleeding sites in each patient group by multiple variable regression analysis, and compared (c) 30-day outcomes, including rebleeding, surgery and deaths. RESULTS: Cirrhosis independently predicted an upper gastrointestinal source of bleeding (OR 3.47; 95 % CI 2.01-5.96) as well as history of hematemesis, melena in the past 30 days, positive nasogastric aspirate, prior upper gastrointestinal bleeding or use of aspirin or non-steroidal anti-inflammatory. The most prevalent diagnoses were esophageal varices (20 %) in cirrhotics and colon diverticular bleeding (27.1 %) in non-cirrhotics. Thirty-day rates of rebleeding, surgical interventions and deaths were 23.1 versus 15 % (P = 0.01), 14.4 versus 6.4 % (P < 0.001), and 17.5 versus 4.1 % (P < 0.001), in cirrhotics versus non-cirrhotics, respectively. CONCLUSIONS: Cirrhosis predicted an upper gastrointestinal site of bleeding in patients presenting with severe hematochezia. The 30-day rates of rebleeding, surgery, and death were significantly higher in cirrhotics than in non-cirrhotics.
