Recurrent obstruction of biliary stent-in-stent: a heated solution.

Intraductal radiofrequency ablation (RFA) has been used in the management of malignant biliary obstruction and ampullary neoplasms. Some small studies refer to its role in managing benign biliary strictures with some promising results. The complications are not neglectable, namely cholangitis, pancreatitis, bleeding, and perforation, although most of them can be managed conservatively. There are two catheters available. Only the ERLA (EndoLumunal Radiofrequency Ablation, Taewoong Medical) catheter can control temperature and impedance, allowing it to reduce the risk of complications.

Acute Treatment of Malignant Colorectal Occlusion: Real Life Practice.

INTRODUCTION: Colorectal cancer presents itself as acute bowel occlusion in 10-40% of patients. There are two main therapeutic approaches: urgent surgery and endoluminal placement self-expandable metallic stents (SEMS). AIMS AND METHODS: This study intended to better clarify the risk/benefit ratio of the above-mentioned approaches. We conducted a retrospective longitudinal multicenter study, including 189 patients with acute malignant colorectal occlusion, diagnosed between January 2005 and March 2013. RESULTS: Globally (85 patients - 35 bridge-to-surgery and 50 palliative), SEMS's technical success was of 94%. Palliative SEMS had limited clinical success (60%) and were associated with 40% of complications. SEMS occlusion (19%) was the most frequent complication, followed by migration (9%) and bowel perforation (7%). Elective surgery after stenting was associated with a higher frequency of primary anastomosis (94% vs. 76%; p = 0.038), and a lower rate of colostomy (26% vs. 55%; p = 0.004) and overall mortality (31% vs. 57%; p = 0.02). However, no significant differences were identified concerning postoperative complications. Regarding palliative treatment, no difference was found in the complications rate and overall mortality between SEMS and decompressive colostomy/ileostomy. In this SEMS subgroup, we found a higher rate of reinterventions (40% vs. 5%; p = 0.004) and a longer hospital stay (14, nine vs. seven, three days; p = 0.004). CONCLUSION: SEMS placement as a bridge-to-surgery should be considered in the acute treatment of colorectal malignant occlusion, since it displays advantages regarding primary anastomosis, colostomy rate and overall mortality. In contrast, in this study, palliative SEMS did not appear to present significant advantages when compared to decompressive colostomy.

INTRODUÇÃO: O cancro colorrectal manifesta-se como oclusão intestinal aguda em 10­40% dos doentes. Existem duas abordagens terapêuticas principais: cirurgia de urgência e prótese endoluminal. OBJECTIVO E MÉTODOS: Este estudo teve como objetivo clarificar o risco/benefício das abordagens mencionadas. Foi realizado um estudo multicêntrico, retrospetivo longitudinal, que incluiu 189 doentes com oclusão colorrectal maligna aguda, diagnosticados entre janeiro de 2005 e março de 2013. RESULTADOS: Globalmente (85 pacientes ­ 35 como ponte para cirurgia e 50 como paliação) a colocação de prótese teve sucesso técnico de 94%. As próteses paliativas apresentaram sucesso clínico limitado (60%) e associaram-se a 40% de complicações. A oclusão tumoral da prótese (19%) foi a complicação mais frequente, seguindo-se a migração (9%) e a perfuração intestinal (7%). A cirurgia eletiva após colocação de prótese associou-se a maior frequência de anastomoses primárias (94% vs 76%; p = 0.038) e a menores taxas de colostomia (26% vs 55%; p = 0.004) e mortalidade (31% vs 57%; p = 0.02). Contudo, não houve diferenças significativas nas complicações pós-cirúrgicas. No tratamento paliativo, a prótese e a colostomia/ileostomia descompressiva não apresentaram diferenças significativas nas complicações ou mortalidade. Neste subgrupo de próteses, observou-se elevada taxa de reintervenção (40% vs 5%; p = 0.004) e de tempo de internamento (14,9 vs 7,3 dias; p = 0.004). CONCLUSÃO: A colocação de prótese como ponte para a cirurgia deve ser considerada no tratamento agudo da oclusão maligna colorrectal, pois apresenta vantagens nas taxas de anastomoses primárias, colostomias e mortalidade. Em contraste, neste estudo as próteses paliativas não apresentaram vantagem clínica significativa em comparação à colostomia descompressiva.

Validation of the Portuguese version of a questionnaire to measure Quality of Care Through the Eyes of Patients with Inflammatory Bowel Disease (QUOTE-IBD).

BACKGROUND/AIM: The patient's perspective on the healthcare that they receive has become increasingly important in the assessment of healthcare quality, especially in chronic diseases such as inflammatory bowel disease (IBD). In this context, the questionnaire QUOTE-IBD (Quality of Care Through the Patient's Eyes with Inflammatory Bowel Disease) was created to assess the healthcare quality from the point of view of a patient with IBD. This questionnaire does not yet have a validated Portuguese version (PT-QUOTE-IBD). We aimed to assess the acceptability, validity, and reliability of PT-QUOTE-IBD. PATIENTS AND METHODS: This was an observational longitudinal unicentric study with three sequential phases: (a) translation and cultural adaptation of QUOTE-IBD that explores the Importance, Performance and Quality Impact of several dimensions of healthcare; (b) assessment of validity by correlation of the results of PT-QUOTE-IBD and visual analogue scales (VAS); and (c) assessment of the reliability of PT-QUOTE-IBD through a second administration of the questionnaire, with a minimum interval of 4 weeks. RESULTS: We included 114 patients with IBD (77 Crohn's disease and 37 ulcerative colitis). Fifty-nine percent of the patients completed all the questions of QUOTE-IBD and VAS. We obtained positive and significant Pearson's correlation coefficients between QUOTE-IBD scores and VAS for Performance and Quality Impact of Total Care and dimensions Accessibility and Information. Thirty-four (30%) patients completed the second questionnaire adequately. We obtained positive and significant Pearson's correlation coefficients between the two questionnaires for Performance and Quality Impact of Total Care, Accessibility, Continuity of Care, Courtesy and Information, and for Performance of Cost. CONCLUSION: PT-QUOTE-IBD is acceptable, valid, and reliable in the assessment of Performance and Quality Impact of Total Care, but not of all dimensions of healthcare.

Oncological outcomes after endoscopic removal of malignant colorectal polyps.

OBJECTIVE: malignant colorectal polyp, defined by submucosally invasive adenocarcinoma, is the earliest form of clinically relevant colorectal cancer (CRC). After endoscopic resection additional surgery may be necessary, although decision criteria remain debatable. The objective of this study was to assess oncologic outcomes in terms of locoregional disease and to identify areas of improvement that may facilitate patients' management. METHODS: retrospective study of 40 patients with T1 CRC endoscopically resected between 2007 and 2012. Clinicopathological features were assessed and correlated with residual disease (RD), defined as presence of adenocarcinoma in intestinal wall and/ or lymph nodes. RESULTS: thirty-one patients underwent surgery while 9 were followed-up. After surgery, RD was confirmed in 15 (48.4%) patients: 8 (53.3%) wall disease, 5 (33%) nodal metastasis, and 2 (13.3%) with both. No recurrence was detected in the follow-up group. The characteristics of the lesions that were associated with DR were sessile configuration (p = 0.03), the degree of differentiation G3 (p = 0.01) and intercepted/indeterminate margins (p = 0.01). Twenty-two patients were operated because of inadequate evaluation, mainly due to piecemeal resection, and half of them were disease free. Postoperative complications were found in 9 (30%) patients, mainly anastomotic leakage that was associated with rectum anterior resection (p = 0.03). CONCLUSIONS: surgery should be considered in the presence of any risk factor for residual disease, while follow-up can be offered in low risk settings. Was also demonstrated a clear need for technical improvement in endoscopic resection and pathology evaluation in order to prevent unnecessary surgeries.
