RESUMO

BACKGROUND/AIMS: Few studies have measured the accuracy of prognostic scores for upper gastrointestinal bleeding (UGIB) among cancer patients. Thereby, we compared the prognostic scores for predicting major outcomes in cancer patients with UGIB. Secondarily, we developed a new model to detect patients who might require hemostatic care. METHODS: A prospective research was performed in a tertiary hospital by enrolling cancer patients admitted with UGIB. Clinical and endoscopic findings were obtained through a prospective database. Multiple logistic regression analysis was performed to gauge the power of each score. RESULTS: From April 2015 to May 2016, 243 patients met the inclusion criteria. The AIMS65 (area under the curve [AUC] 0.85) best predicted intensive care unit admission, while the Glasgow-Blatchford score best predicted blood transfusion (AUC 0.82) and the low-risk group (AUC 0.92). All scores failed to predict hemostatic therapy and rebleeding. The new score was superior (AUC 0.74) in predicting hemostatic therapy. The AIMS65 (AUC 0.84) best predicted in-hospital mortality. CONCLUSION: The scoring systems for prognostication were validated in the group of cancer patients with UGIB. A new score was developed to predict hemostatic therapy. Following this result, future prospective research should be performed to validate the new score.

RESUMO

BACKGROUND AND AIMS: Malignant esophagorespiratory fistulas (MERFs) usually are managed by the placement of self-expandable metal stents (SEMSs) but with conflicting results. This study aimed to identify risk factors associated with clinical failure after SEMS placement for the treatment of MERFs. METHODS: This was a retrospective analysis of a prospectively maintained database used at a tertiary-care cancer hospital, with patients treated with SEMS placement for MERFs between January 2009 and February 2016. Logistic regression was used to identify predictive factors for clinical outcomes and to estimate the odds ratio (OR) and the 95% confidence interval (CI). The Kaplan-Meier method was used for survival analysis, and comparisons were made by using the log-rank test. RESULTS: A total of 71 patients (55 male, mean age 59 years) were included in the study, and 70 were considered for the final analysis (1 failed stent insertion). Clinical failure occurred in 44% of patients. An Eastern Cooperative Oncology Group (ECOG) performance status of 3 or 4 and fistula development during esophageal cancer treatment were associated with an increased risk of clinical failure. ECOG status of 3 or 4, pulmonary infection at the time of SEMS placement, and prior radiation therapy were predictive factors associated with lower overall survival. Dysphagia scores improved significantly 15 days after stent insertion. The overall stent-related adverse event rate was 30%. Stent migration and occlusion caused by tumor overgrowth were the most common adverse events. CONCLUSION: SEMS placement is a reasonable treatment option for MERFs; however, ECOG status of 3 or 4 and fistula development during esophageal cancer treatment may be independent predictors of clinical failure after stent placement.

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.

RESUMO

ABSTRACT BACKGROUND Gastric subepithelial lesion is a relatively common diagnosis after routine upper endoscopy. The diagnostic workup of an undetermined gastric subepithelial lesion should take into consideration clinical and endoscopic features. OBJECTIVE We aimed to investigate the association between patients' characteristics, endoscopic and echographic features with the histologic diagnosis of the gastric subepithelial lesions. METHODS This is a retrospective study with 55 patients, who were consecutively diagnosed with gastric subepithelial lesions, from October 2008 to August 2011. Patients' characteristics, endoscopic and echografic features of each gastric subepithelial lesion were analysed. Histologic diagnosis provided by EUS-guided fine needle aspiration or endoscopic/surgical resection was used as gold standard. RESULTS The probability of gastrointestinal stromal tumors to be located in the cardia was low (4.5%), while for leiomyoma it was high (>95%). In addition, there was a higher risk of gastrointestinal stromal tumors in patients older than 57 years (OR 8.9; 95% CI), with lesions ≥21 mm (OR 7.15; 95% CI), located at 4th layer (OR 18.8; 95% CI), with positive Doppler sign (OR 9; 95% CI), and irregular outer border (OR 7.75; 95% CI). CONCLUSION The location of gastric subepithelial lesions in the gastric cardia lowers the risk of gastrointestinal stromal tumors. While gastric subepithelial lesions occurring in elderly patients, located in the gastric body, with positive Doppler signal and irregular outer border increase the risk of gastrointestinal stromal tumors.

RESUMO CONTEXTO O diagnóstico das lesões subepiteliais gástricas é relativamente comum após a endoscopia digestiva alta de rotina. A posterior investigação diagnóstica de uma lesão subepitelial gástrica indeterminada deve levar em consideração os aspectos clínicos e endoscópicos. OBJETIVO O objetivo foi avaliar a associação entre as características particulares dos pacientes, endoscópicas e ecográficas dos casos de lesões subepiteliais gástricas com os seus diagnósticos histológicos finais. MÉTODOS Estudo retrospectivo com 55 pacientes, consecutivamente diagnosticados com lesão subepitelial gástrica de outubro de 2008 a agosto de 2011. As características do paciente, endoscópica e ecográfica de cada caso com lesão subepitelial gástrica foram analisadas. O diagnóstico histológico fornecido pela punção aspirativa com agulha fina guiada por ecoendoscopia e/ou a ressecção endoscópica/cirúrgica foram utilizadas como padrão-ouro. RESULTADOS A probabilidade de tumor estromal gastrintestinal ser localizado na cárdia foi baixa (4,5%), enquanto que para o leiomioma foi elevada (>95%). Além disso, houve um maior risco de tumor estromal gastrintestinal em pacientes acima de 57 anos (OR 8,9; IC 95%), com lesão ≥21 mm (OR 7,15; IC 95%), localizada na 4ª camada (OR 18,8; IC 95%), com sinal positivo no Doppler (OR 9; IC 95%), e borda externa irregular (OR 7,75; IC 95%). CONCLUSÃO A localização de uma lesão subepitelial gástrica na cárdia reduz o risco de tumor estromal gastrintestinal. Enquanto que lesões subepiteliais gástricas que ocorrem em pacientes idosos, localizadas no corpo gástrico, com sinal positivo no Doppler e com borda externa irregular aumentam significativamente o risco de tumor estromal gastrintestinal.

RESUMO

Subepithelial lesions (SELs) in the upper gastrointestinal (GI) tract are relatively frequent findings in patients undergoing an upper GI endoscopy. These tumors, which are located below the epithelium and out of reach of conventional biopsy forceps, may pose a diagnostic challenge for the gastroenterologist, especially when SELs are indeterminate after endoscopy and endoscopic ultrasound (EUS). The decision to proceed with further investigation should take into consideration the size, location in the GI tract, and EUS features of SELs. Gastrointestinal stromal tumor (GIST) is an example of an SEL that has a well-recognized malignant potential. Unfortunately, EUS is not able to absolutely differentiate GISTs from other benign hypoechoic lesions from the fourth layer, such as leiomyomas. Therefore, EUS-guided fine needle aspiration (EUS-FNA) is an important tool for correct diagnosis of SELs. However, small lesions (size < 2 cm) have a poor diagnostic yield with EUS-FNA. Moreover, studies with EUS-core biopsy needles did not report higher rates of histologic and diagnostic yields when compared with EUS-FNA. The limited diagnostic yield of EUS-FNA and EUS-core biopsies of SELs has led to the development of more invasive endoscopic techniques for tissue acquisition. There are initial studies showing good results for tissue biopsy or resection of SELs with endoscopic submucosal dissection, suck-ligate-unroof-biopsy, and submucosal tunneling endoscopic resection.
