- A rare non-oncological pancreatic mass: eosinophilic pancreatitis diagnosis through EUS-FNA(2019) MOURA, Diogo Turiani Hourneaux De; ROCHA, Rodrigo Silva de Paula; JUKEMURA, Jose; BRUNALDI, Vitor Ottoboni; GUEDES, Hugo Goncalo; TORREZ, Franz Robert Apodaca; RIBEIRO, Igor Braga; GELRUD, Andres; MOURA, Eduardo Guimaraes Hourneaux DeBackground and study aims Eosinophilic pancreatitis (EP) is a rare etiology of chronic pancreatitis, and few cases have been reported. It is characterized by eosinophilic infiltration of the pancreas and elevated IgE levels. EP is difficult to distinguish from pancreatic cancer based on clinical symptoms and auxiliary exams. We present a case of EP and debate the routine performance of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for resectable pancreatic mass.
- Nonsteroidal anti-inflammatory drugs versus placebo for post-endoscopic retrograde cholangiopancreatography pancreatitis: a systematic review and meta-analysis(2019) SERRANO, Juan Pablo Roman; MOURA, Diogoturiani Hourneaux de; BERNARDO, Wanderley Marques; RIBEIRO, Igor Braga; FRANZINI, Tomazo Prince; MOURA, Eduardo Turiani Hourneaux de; BRUNALDI, Vitor Ottoboni; SALESSE, Marianne Torrezan; SAKAI, Paulo; MOURA, Eduardo Guimaraes Hourneaux DeBackground and study aims Endoscopic retrograde cholangiopancreatography (ERCP) is the primary therapeutic procedure for treatment of diseases that affect the biliary tree and pancreatic duct. While the therapeutic success rate of ERCP is high, the procedure can cause complications, such as acute pancreatitis (PEP), bleeding, and perforation. This meta-analysis aimed to assess the efficacy of nonsteroidal anti-inflammatory drugs (NSAIDs) in preventing PEP following (ERCP). Materials and methods We searched databases, such as MEDLINE, Embase, and Cochrane Central Library. Only randomized controlled trials (RCTs) that compared the efficacy of NSAIDs and placebo for the prevention of PEP were included. Outcomes assessed included incidence of PEP, severity of pancreatitis, route of administration, and type of NSAIDs. Results Twenty-one RCTs were considered eligible with a total of 6854 patients analyzed. Overall, 3427 patients used NSAIDs before ERCP and 3427 did not use the drugs (control group). In the end, 250 cases of acute pancreatitis post-ERCP were diagnosed in the NSAIDs group and 407 cases in the placebo group. Risk for PEP was lower in the NSAID group (risk difference (RD): -0.05; 95% confidence interval (CI): -0.07 to -0.03; number need to treat (NNT), 20; P<0.05). Use of NSAIDs effectively prevented mild pancreatitis compared with use of placebo (2.5% vs. 4.1%; 95% CI, -0.05 to -0.01; NNT, 33; P<0.05), but the information on moderate and severe PEP could not be completely elucidated. Only rectal administration reduced incidence of PEP (6.8% vs. 13 %; 95% CI, -0.10 to -0.04; NNT, 20; P<0.05). Furthermore, only diclofenac or indomethacin use was effective in preventing PEP. Conclusions Rectal administration of diclofenac and indomethacin significantly reduced risk of developing mild PEP. Further RCTs are needed to compare efficacy between NSAID administration pathways in prevention of PEP after ERCP.

article 0 Citação(ões) na Scopus Gastrointestinal ischemia: endoscopic findings in the context of vascular insufficiency(2019) HOURNEAUX DE MOURA, Diogo Turiani; MADRUGA NETO, Antonio C; BARSOTTI, Gabriel C; CORONEL, Martin; GUEDES, Hugo G; BRUNALDI, Vitor O; ARTIFON, Everson L.A; DE MOURA, Eduardo G.HGastrointestinal ischemia may result from different causes: hemodynamic shock, thromboembolism, endoscopic or surgical complications, among other causes. Its symptoms are pain, vomiting, bleeding and bloating. Endoscopic findings are pale or blackened mucosa, and exudative and confluent ulcerative lesions. This paper aims to report a case of gastroduodenal ischemia associated with hemodynamic shock and disseminated intravascular coagulation (DIC). This is a case of a 56-yearsold male with multiple comorbidities, presenting with refractory septic shock and DIC. He underwent an upper gastrointestinal endoscopy (UGE) for investigation of melena, which revealed an extensive deep and exudative gastric ulcer, associated with edematous purplish duodenal mucosa. Due to the severity of the underlying condition, the patient evolved to death, evidencing septic shock as cause of death. Gastroduodenal ischemia is associated with a poor prognosis, in which early diagnosis by UGE is fundamental to guide potential interventions.- ENDOSCOPIC FINDINGS IN SEVERE YELLOW FEVER PATIENTS PRESENTING WITH ACUTE UPPER GASTROINTESTINAL BLEEDING: A RETROSPECTIVE CASE SERIES STUDY(2019) GALETTI, Facundo; FARIAS, Galileu F.; MARTINS, Rafael K.; CORONEL, Martin A.; REZENDE, Daniel T.; ROCHA, Rodrigo S.; MOURA, Diogo T. de; BRUNALDI, Vitor O.; HO, Yeh-Li; BABA, Elisa; MOURA, Eduardo G. de
- EUS-Guided Intragastric Injection of Botulinum Toxin A in the Preoperative Treatment of Super-Obese Patients: a Randomized Clinical Trial(2019) MOURA, Eduardo Guimaraes Hourneaux de; RIBEIRO, Igor Braga; FRAZAO, Mariana Souza Varela; MESTIERI, Luiz Henrique Mazzonetto; MOURA, Diogo Turiani Hourneaux de; BO, Creusa Maria Roveri Dal; BRUNALDI, Vitor Ottoboni; MOURA, Eduardo Turiani Hourneaux de; NUNES, Gabriel Cairo; BUSTAMANTE, Fabio Alberto Castillo; GALVAO NETO, Manoel dos Passos; MATUGUMA, Sergio Eiji; BERNARDO, Wanderley Marques; SANTO, Marco AurelioBackgroundObesity is a disease that is highly prevalent in Brazil, and the associated comorbidities represent a major global public health challenge. Botulinum toxin type A (BTX-A) is a potent neurotoxin and inhibitor of gastric smooth muscle activity. In theory, BTX-A administration should promote early satiety and weight loss because it delays gastric emptying by inhibiting acetylcholine-mediated peristalsis, which is primarily responsible for gastric motility. Because results in the literature are discrepant, the efficacy of intragastric injections of BTX-A as a primary treatment for obesity remains unknown. The objective of this prospective, double-blind, single-center randomized study was to evaluate the effects of endoscopic ultrasound-guided intragastric BTX-A injections, as a bridge to bariatric surgery, in super-obese patients.MethodsThirty-two super-obese patients were randomized to one of two groups: BTX-A, in which 200units of BTX-A were injected into the gastric antrum and body; and control, in which the same injections were performed with 0.9% saline. Weight, body mass index (BMI), and loss of excess weight were measured monthly over a 6-month period. Gastric emptying scintigraphy was performed before and after the procedure.ResultsThe patients in both groups showed significant weight loss over the course of the study (p<0.001). There were no statistically significant differences between the groups regarding weight loss, excess weight, total loss of excess weight, total weight loss, or change in BMI.ConclusionsIntragastric injection of BTX-A does not appear to be an effective method of achieving preoperative weight loss in super-obese patients.
