- Papillary fistulotomy vs conventional cannulation for endoscopic biliary access: A prospective randomized trial(2018) FURUYA, Carlos Kiyoshi; SAKAI, Paulo; MARINHO, Fabio Ramalho Tavares; OTOCH, Jose Pinhata; CHENG, Spencer; PRUDENCIO, Livia Lemes; MOURA, Eduardo Guimaraes Hourneaux de; ARTIFON, Everson Luiz de AlmeidaAIM To compare the cannulation success, biochemical profile, and complications of the papillary fistulotomy technique vs catheter and guidewire standard access. METHODS From July 2010 to May 2017, patients were prospectively randomized into two groups: Cannulation with a catheter and guidewire (Group.) and papillary fistulotomy (Group.). Amylase, lipase and C-reactive protein at T0, as well as 12 h and 24 h after endoscopic retrograde cholangiopancreatography, and complications (pancreatitis, bleeding, perforation) were recorded. RESULTS We included 102 patients (66 females and 36 males, mean age 59.11 +/- 18.7 years). Group. and Group. had 51 patients each. The successful cannulation rates were 76.5% and 100%, respectively (P = 0.0002). Twelve patients (23.5%) in Group. had a difficult cannulation and underwent fistulotomy, which led to successful secondary biliary access (Failure Group). The complication rate was 13.7% (2 perforations and 5 mild pancreatitis) vs 2.0% (1 patient with perforation and pancreatitis) in Groups. and., respectively (P = 0.0597). CONCLUSION Papillary fistulotomy was more effective than guidewire cannulation, and it was associated with a lower profile of amylase and lipase. Complications were similar in both groups.
- Técnica modificada para realização da gastro-jejunostomia endoscópica percutânea(2017) RUIZ, Renzo Feitosa; FRANCO, Matheus Cavalcante; FURUYA JÚNIOR, Carlos Kiyoshi; DOS-SANTOS, Marcos Eduardo LeraABSTRACT The placement of percutaneous endoscopic gastrojejunostomy (PEG-J) provides diet delivery beyond the angle of Treitz, and it is associated with decrease of complications related to gastroparesis, such as aspiration pneumonia. There are many different techniques to perform a PEG-J described in the literature, with variable degrees of technical success. In this article, we suggest modifications to the technique of PEG-J placement in order to reduce time of procedure and minimize the risk of technical failure.
- Morphological alterations of upper gastrointestinal tract in patients with new onset-dermatomyositis: correlation with demographic, clinical and laboratory features(2017) AMORIM, Thammi de Matos; FURUYA JUNIOR, Carlos Kiyoshi; MARQUES, Sergio Barbosa; SHINJO, Samuel KatsuyukiOBJECTIVE: To endoscopically assess the upper digestive tract of adult patients with newly diagnosed dermatomyositis; to correlate possible changes in the gastrointestinal tract with demographic, clinical and laboratory features in this population. METHOD: A cross-sectional study evaluating 65 newly diagnosed dermatomyositis cases from 2004 to 2015 was carried out. We excluded patients with clinically amyopathic dermatomyositis, overlap dermatomyositis, polymyositis, liver diseases, prior gastric surgery, upper gastrointestinal tract symptoms (except for upper dysphagia), systemic infections, alcohol consumption and smoking. RESULTS: Mean age of patients was 44.9 years, with disease duration of four months. Endoscopic findings were observed in 70.8% of patients. (1) Esophageal disease/gastric distress was documented in 18.5% of patients: erosive distal esophagitis (16.9%) and non-erosive distal esophagitis distal (1.5%); (2) gastric distress in 63.1% of cases: antral gastritis (42.3%) and pangastritis (27.8%); (3) duodenal involvement in 15.4% of patients: bulbar duodenitis (10.9%) and duodenal ulcers (7.7%). There were no neoplasic lesions. On multivariate analysis, erosive distal esophagitis was less associated with older patients. Males had a higher prevalence of erosive gastritis. Enanthematous pangastritis was less associated with lesions with ""V-neck"" sign lesions. CONCLUSIONS: This study provides the first estimates of the prevalence of high endoscopic findings in adult patients with newly diagnosed dermatomyositis. The results may be relevant to guide conduct in digestive disorders with upper digestive endoscopy, and point to the need for pharmacological prevention of digestive tract lesions in these patients. Further studies are needed to validate this data and evaluate patients with dyspeptic symptoms.
- AN INNOVATIVE EX-VIVO MODEL FOR RAPID CHANGE OF THE PAPILLA FOR TEACHING ADVANCED ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY PROCEDURES(2016) ARTIFON, Everson L.A.; NAKADOMARI, Thaisa S.; KASHIWAGUI, Leandro Y.; BELMONTE, Emilio A.; SOLAK, Cláudio R.; CHENG, Spencer; FURUYA JR, Carlos K.; OTOCH, Jose P.ABSTRACT Background: Models for endoscopic retrograde cholangiopancreatography training allow practice with an expert feedback and without risks. A method to rapidly exchange the papilla can be time saving and accelerate the learning curve. Aim: To demonstrate a newly method of rapid exchange papilla in ex-vivo models to teach retrograde cholangiopancreatography advanced procedures. Methods: A new model of ex-vivo papilla was developed in order to resemble live conditions of procedures as cannulation, papilotomy or fistula-papilotomy, papiloplasty, biliary dilatation, plastic and metallic stentings. Results: The ex-vivo model of papilla rapid exchange is feasible and imitates with realism conditions of retrograde cholangiopancreatography procedures. Conclusion: This model allows an innovative method of advanced endoscopic training.
article 8 Citação(ões) na Scopus Surgical or endoscopic management for post-ERCP large transmural duodenal perforations: a randomized prospective trial(2015) ARTIFON, Everson L. A; K. MINATA, Mauricio; B. CUNHA, Marco Antonio; P. OTOCH, Jose; P. APARICIO, Dayse; K. FURUYA, Carlos; B. PAIONE, José L.Introduction: Duodenal perforations are an uncommon adverse event during ERCP. Patients can develop significant morbidity and mortality. Even though surgery has been used to manage duodenal complications, therapeutic endoscopy has seen significant advances. Objective: To compare endoscopic approach with surgical intervention in patients with duodenal perforations post-ERCP. Material and Methods: prospective randomized study in a tertiary center with 23 patients divided in 2 groups. Within 12 hours after the event, the patients underwent endoscopic or surgical approach. Endoscopic approach included closure of the perforation with endoclips and SEMS. Surgical repair included hepaticojejunostomy, suture of the perforation or duodenal suture. The success was defined as closure of the defect. Secondary outcomes included mortality, adverse events, days of hospitalization and costs. Results: The success was 100% in both groups. There was one death in the endoscopic group secondary to sepsis. There was no statistical difference in mortality or adverse events. We noticed statistical difference in favor of the endoscopic group considering shorter hospitalization (4.1 days versus 15.2 days, with p=0.0123) and lower cost per patient (U$14,700 versus U$19,872, with p=0.0103). Conclusions: Endoscopic approach with SEMS and endoclips is an alternative to surgery in large transmural duodenal perforations post-ERCP- Tube-in-tube endoscopic vacuum therapy for treatment of colorectal anastomotic leaks: A low-cost, patient-friendly, feasible and efficient technical modification of sponge-based endoscopic vacuum therapy(2023) LIMA, Marcelo Simas de; FIGUEIREDO, Lucas Zouain; FURUYA, Carlos Kiyoshi; POMBO, Amanda Aquino de Miranda; HORA, Jose Americo Bacchi; MALLUF-FILHO, FauzeBackground and Aims: Colorectal endoscopic vacuum therapy (CR EVT) is usually performed using sponges passed through the anus. It may be associated with patient discomfort and displacement of the aspiration tube. Methods: With the tube-in-tube endoscopic vacuum therapy modification (CR TT-EVT), it is possible to position the aspiration tube in the pelvic cavity through the abdominal wall. In addition, it allows frequent cleaning of the fistula, eliminates the need for programmed device changes, and enables a standardized approach to such a wide variety of fistulas, leaks, and perforations. Results: Here is a technical note on how to perform CR TT-EVT, while we are at the early phase of our case series we have reached 100% of technical success.
- Endoscopic stenting for inoperable malignant biliary obstruction: A systematic review and meta-analysis(2015) PU, Leonardo Zorron; MOURA, Eduardo Guimaraes Hourneaux de; BERNARDO, Wanderley Marques; BARACAT, Felipe Iankelevich; MENDONCA, Ernesto Quaresma; KONDO, Andre; LUZ, Gustavo Oliveira; FURUYA JUNIOR, Carlos Kiyoshi; ARTIFON, Everson Luiz de AlmeidaAIM: To analyze through meta-analyses the benefits of two types of stents in the inoperable malignant biliary obstruction. METHODS: A systematic review of randomized clinical trials (RCT) was conducted, with the last update on March 2015, using EMBASE, CINAHL (EBSCO), MEDLINE, LILACS/CENTRAL (BVS), SCOPUS, CAPES (Brazil), and gray literature. Information of the selected studies was extracted in sight of six outcomes: primarily regarding dysfunction, complication and reintervention rates; and secondarily costs, survival, and patency time. The data about characteristics of trial participants, inclusion and exclusion criteria and types of stents were also extracted. The bias was mainly assessed through the JADAD scale. This meta-analysis was registered in the PROSPERO database by the number CRD42014015078. The analysis of the absolute risk of the outcomes was performed using the software RevMan, by computing risk differences (RD) of dichotomous variables and mean differences (MD) of continuous variables. Data on RD and MD for each primary outcome were calculated using the Mantel-Haenszel test and inconsistency was qualified and reported in chi(2) and the Higgins method (I-2). Sensitivity analysis was performed when heterogeneity was higher than 50%, a subsequent assay was done and other findings were compiled. Student's t-test was used for the comparison of weighted arithmetic means regarding secondary outcomes. RESULTS: Initial searching identified 3660 studies; 3539 were excluded through title, repetition, and/or abstract, while 121 studies were fully assessed and were excluded mainly because they did not compare self-expanding metal stents (SEMS) and plastic stents (PS), leading to thirteen RCT selected, with 13 articles and 1133 subjects meta-analyzed. The mean age was 69.5 years old, that were affected mostly by bile duct (proximal) and pancreatic tumors (distal). The preferred SEMS diameter used was the 10 mm (30 Fr) and the preferred PS diameter used was 10 Fr. In the meta-analysis, SEMS had lower overall stent dysfunction compared to PS (21.6% vs 46.8%, P < 0.00001) and fewer re-interventions (21.6% vs 56.6%, P < 0.00001), with no difference in complications (13.7% vs 15.9%, P = 0.16). In the secondary analysis, the mean survival rate was higher in the SEMS group (182 d vs 150 d, P < 0.0001), with a higher patency period (250 d vs 124 d, P < 0.0001) and a lower cost per patient (4193.98 vs 4728.65 Euros, P < 0.0985). CONCLUSION: SEMS are associated with lower stent dysfunction, lower re-intervention rates, better survival, and higher patency time. Complications and costs showed no difference.
- Endoscopic palliative treatment versus surgical bypass in malignant low bile duct obstruction: A systematic review and meta-analysis(2015) LIMA, Silvia Lucia Alves de; BUSTAMANTE, Fabio Alberto Castillo; MOURA, Eduardo Guimaraes Hourneaux de; BERNARDO, Wanderley Marques; ARTIFON, Everson Luiz de Almeida; CHAVES, Dalton Marques; FRANZINI, Tomazo Antonio Prince; FURUYA JUNIOR, Carlos KiyoshiAims: Despite technological advances, only about 20% of periampullary tumors are found to be resectable at the time of presentation. Biliary tree obstruction and consequent jaundice occur in 70-90% of those patients and has important consequences for a patient's quality of life. Relief of biliary tree obstruction is the main goal for treatment, and few options for palliative therapy of biliary tree obstruction can be performed, including surgical bypass, percutaneous stenting, and endoscopic stenting. Objective: The aim of the present study was to acquire and analyze data to compare the success of procedures, procedure-related complication, mortality in 30 days, recurrent-jaundice rates in endoscopic, and surgical palliative techniques. Methods: Two independent reviewers searched the following electronic databases: Medline, EMBASE, Cochrane, LILACS, BVS, SCOPE, and CINAHL (EBSCO). Inclusion criteria included studies involving patients with distal biliary obstruction due to periampullary tumors who underwent endoscopic therapy or a surgical procedure for palliation. Results: No differences were observed for success of procedures; differences were observed with better outcomes for endoscopy therapy with regards to mortality associated with procedure, complication associated with procedure, and mortality in 30 days. Also, differences were observed with better outcomes for surgery therapy for recurrent-jaundice. Conclusion: Endoscopic palliative drainage is associated with a lower rate in complication, mortality associated with procedure, and mortality in 30 days. Recurrent-jaundice analysis demonstrated an overall lower rate in surgical bypass procedures. No differences were found for the success of procedures.
