RESUMO

BACKGROUND 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.

RESUMO

BACKGROUND: Many studies evaluated magnification endoscopy (ME) to correlate changes on the gastric mucosal surface with Helicobacter pylori (H. pylori) infection. However, few studies validated these concepts with high-definition endoscopy without ME. AIM: To access the association between mucosal surface pattern under near focus technology and H. pylori infection status in a western population. METHODS: Cross-sectional study including all patients referred to routine upper endoscopy. Endoscopic exams were performed using standard high definition (S-HD) followed by near focus (NF-HD) examination. Presence of erythema, erosion, atrophy, and nodularity were recorded during S-HD, and surface mucosal pattern was classified using NF-HD in the gastric body. Biopsies were taken for rapid urease test and histology. RESULTS: One hundred and eighty-seven patients were analyzed from August to November 2019. Of those, 47 (25.1%) were H. pylori+, and 42 (22.5%) had a previous H. pylori treatment. In the examination with S-HD, erythema had the best sensitivity for H. pylori detection (80.9%). Exudate (99.3%), nodularity (97.1%), and atrophy (95.7%) demonstrated better specificity values, but with low sensitivity (6.4%-19.1%). On the other hand, the absence of erythema was strongly associated with H. pylori- (negative predictive value = 92%). With NF-HD, 56.2% of patients presented type 1 pattern (regular arrangement of collecting venules, RAC), and only 5.7% of RAC+ patients were H. pylori+. The loss of RAC presented 87.2% sensitivity for H. pylori detection, 70.7% specificity, 50% positive predictive value, and 94.3% negative predictive value, indicating that loss of RAC was suboptimal to confirm H. pylori infection, but when RAC was seen, H. pylori infection was unlikely. CONCLUSION: The presence of RAC at the NF-HD exam and the absence of erythema at S-HD were highly predictive of H. pylori negative status. On the other hand, the loss of RAC had a suboptimal correlation with the presence of H. pylori.

RESUMO

BACKGROUND: Endoscopic aspect of fundoplication anatomy: Normal aspect of Nissen fundoplication. Upper digestive endoscopy is important for the evaluation of patients submitted to fundoplication, especially to elucidate postoperative symptoms. However, endoscopic assessment of fundoplication anatomy and its complications is poorly standardized among endoscopists, which leads to inadequate agreement. AIM: To assess the frequency of postoperative abnormalities of fundoplication anatomy using a modified endoscopic classification and to correlate endoscopic findings with clinical symptoms. METHOD: This is a prospective observational study, conducted at a single center. Patients were submitted to a questionnaire for data collection. Endoscopic assessment of fundoplication was performed according to the classification in study, which considered four anatomical parameters including the gastroesophageal junction position in frontal view (above or at the level of the pressure zone); valve position at retroflex view (intra-abdominal or migrated); valve conformation (total, partial, disrupted or twisted) and paraesophageal hernia (present or absent). RESULTS: One hundred patients submitted to fundoplication were evaluated, 51% male (mean age: 55.6 years). Forty-three percent reported postoperative symptoms. Endoscopic abnormalities of fundoplication anatomy were reported in 46% of patients. Gastroesophageal junction above the pressure zone (slipped fundoplication), and migrated fundoplication, were significantly correlated with the occurrence of postoperative symptoms. There was no correlation between symptoms and conformation of the fundoplication (total, partial or twisted). CONCLUSION: This modified endoscopic classification proposal of fundoplication anatomy is reproducible and seems to correlate with symptomatology. The most frequent abnormalities observed were slipped and migrated fundoplication, and both correlated with the presence of symptoms.

RESUMO Racional: A endoscopia digestiva alta é importante ferramenta para a avaliação de pacientes submetidos à fundoplicatura, principalmente para elucidar os sintomas pós-operatórios. Entretanto, a avaliação endoscópica da sua anatomia e complicações é atualmente pouco padronizada entre os endoscopistas, o que leva à disparidade de laudos e condutas. Objetivo: Avaliar a frequência de anormalidades pós-operatórias da fundoplicatura através de uma classificação endoscópica e correlacionar os achados endoscópicos com os sintomas clínicos. Método: Este é estudo observacional prospectivo, realizado em um único centro. Os pacientes foram submetidos a um questionário para coleta de dados. A avaliação endoscópica da fundoplicatura foi realizada de acordo com a classificação em estudo, que considerou quatro parâmetros anatômicos, incluindo a posição da junção gastroesofágica em vista frontal (acima ou no nível da zona de pressão); posição da válvula na visão retroflexa (intra-abdominal ou migrada); conformação valvar (total, parcial, desgarrada ou torcida) e hérnia paraesofágica (presente ou ausente). Resultados: Foram avaliados 100 pacientes submetidos à fundoplicatura, 51% homens (idade média: 55,6 anos). Quarenta e três por cento relataram sintomas pós-operatórios. Anormalidades endoscópicas da anatomia da fundoplicatura foram relatadas em 46% dos pacientes. Junção gastroesofágica acima da zona de pressão (fundoplicatura deslizada) e fundoplicatura migrada foram significativamente correlacionadas com a ocorrência de sintomas pós-operatórios. Não houve correlação entre sintomas e conformação da fundoplicatura (total, parcial ou torcida). Conclusão: Essa classificação endoscópica modificada proposta para avaliar a anatomia da fundoplicatura é reprodutível e parece correlacionar-se com a sintomatologia. As anormalidades mais frequentes observadas foram fundoplicaturas migradas e deslizadas, e ambas se correlacionaram com a presença de sintomas.

RESUMO

AIM: 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 I) and papillary fistulotomy (Group II). 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 I and Group II had 51 patients each. The successful cannulation rates were 76.5% and 100%, respectively (P = 0.0002). Twelve patients (23.5%) in Group I 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 I and II, 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.

RESUMO

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.


A realização da gastro-jejunostomia endoscópica percutânea (PEG-J) proporciona nutrição além do ângulo de Treitz, e está associada à diminuição das complicações relacionadas à gastroparesia, como a pneumonia por aspiração. Existem diversas técnicas para realização da PEG-J descritas na literatura, com graus variáveis de sucesso técnico. Neste artigo propomos modificações na técnica de realização da PEG-J, a fim de reduzir o tempo do procedimento e minimizar o risco de insucesso.

RESUMO

Double-balloon enteroscopy (DBE) is a useful method for endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y anatomy. Depending on the distorted anatomy, endoscopic therapies with conventional scopes were very difficult or impossible before the advent of DBE and patients had to be submitted to a percutaneous or surgical approach. The case of 6 patients with different types of Roux-en-Y-altered anatomy in which DBE-ERCP was performed with 83.3% successful rate (5/6) is reported confirming recent data in the literature on the feasibility of this method.
