3% polidocanol foam sclerotherapy versus hemorrhoidal artery ligation with recto anal repair in hemorrhoidal disease grades II-III: a randomized, pilot trial.

PURPOSE: Polidocanol foam sclerotherapy (SP) versus doppler-guided hemorrhoidal artery ligation with recto-anal repair (HAL-RAR) in the treatment of hemorrhoidal disease (HD) was analyzed. METHODS: A prospective, randomized study including patients with HD grades II and III was performed. Participants were randomly assigned (1:1) into SP or HAL-RAR, during a recruitment period between September 2019 and February 2020. Therapeutic success (Sodergren's and bleeding scores) was the primary outcome. Other outcomes evaluated included complications and implication in the professional life. Efficacy and safety outcomes were evaluated during the 8 weeks after surgery or the final SP session. RESULTS: Forty-six patients were allocated either to SP (n=22) or HAL-RAR (n=24). Most patients achieved therapeutic success (SP 100% vs. HAL-RAR 90.9%, p=0.131). Complete success was higher in the SP group (91.7% vs. 68.2%, p=0.045) and SP patients had less complications (25% vs. 68.2%, p=0.003). HAL-RAR had a greater negative impact on work activity of the patient. CONCLUSION: SP was more effective and safer than HAL-RAR. SP patients had less impact on their work activity.

Office-Based Procedures in the Management of Hemorrhoidal Disease: Rubber Band Ligation versus Sclerotherapy - Systematic Review and Meta-Analysis.

Introduction: The most frequently used office-based procedures in hemorrhoidal disease (HD) are rubber band ligation (RBL) and sclerotherapy. Few studies have been published comparing the various types of instrumental therapy. The aim of this systematic review and meta-analysis was to compare the efficacy and safety of sclerotherapy and RBL. Methods: Three online databases were searched. Efficacy (control of symptoms, prolapse, bleeding and pain, patients' satisfaction, and disease recurrence) and safety (complications, such as pain and bleeding) were the assessed outcomes. Pooled relative risks (RR) were computed for each outcome using a random-effects model, and heterogeneity was assessed by Cochran's Q test and I2. Results: Six RCTs and three cohort studies were included. Control of prolapse and bleeding was significantly higher with RBL (93.1% RBL vs. 66.4% sclerotherapy, RR 1.34, 95% CI 1.12-1.60 and 89.1% RBL vs. 78.7% SCL, RR 1.17, 95% CI 1.02-1.34, respectively). Both techniques had similar results in terms of pain relief, overall control of symptoms, and risk of recurrence at 3 months. Although patient satisfaction was significantly higher with RBL (77.8% RBL vs. 46.7% sclerotherapy, RR 1.59, 95% CI 1.01-2.50), post-procedural pain was significantly higher with this technique (24% RBL vs. 14% sclerotherapy, RR 1.74, 95% CI 1.32-2.28). There was no significant difference regarding post-procedure bleeding (11.1% RBL vs. 8.7% sclerotherapy, RR 1.29, 95% CI 0.86-1.94). In the subgroup analysis, according to the HD grade, post-procedure pain was higher with RBL only in HD grade II (vs. HD grade I-III). Conclusions: RBL performs better than sclerotherapy in controlling HD symptoms, specifically prolapse and bleeding, although post-procedural pain is a frequent complication. Recurrence is similar with both procedures. While waiting for the publication of results with sclerotherapy with new sclerosants, RBL remains the office-based treatment of choice in HD.

Contexto/Objetivos: Os tratamentos instrumentais mais frequentemente realizados na doença hemorroidária (DH) são a laqueação elástica (LE) e a escleroterapia. Existem poucos estudos publicados que comparem os vários tipos de tratamento instrumental. O objetivo desta revisão sistemática e meta-análise foi comparar a eficácia e a segurança da escleroterapia e da LE. Métodos: A pesquisa foi feita em três bases de dados. A eficácia (controlo dos sintomas, do prolapso, da hemorragia e da dor, satisfação dos doentes e recorrência da DH) e a segurança (complicações, tais como dor e hemorragia) foram os resultados avaliados. Os riscos relativos (RR) foram calculados para cada resultado, com recurso a um modelo de efeitos aleatórios, e a heterogeneidade foi avaliada pelo teste Q de Cochran e I2. Resultados: Foram incluídos seis estudos clínicos randomizados e três estudos de coorte. O controlo do prolapso e da hemorragia foi significativamente mais elevado com a LE (93,1% LE VS 66,4% escleroterapia, RR 1,34, 95% CI 1,12-1,60 e 89,1% LE VS 78,7% escleroterapia, RR 1,17, 95% CI 1,02-1,34, respetivamente). Ambas as técnicas tiveram resultados semelhantes em termos de alívio da dor, controlo global dos sintomas e risco de recidiva aos 3 meses. Embora a satisfação dos doentes fosse significativamente maior com LE (77,8% LE VS 46,7% escleroterapia, RR 1,59 95% CI 1,01-2,50), a dor pós-procedimento foi significativamente maior com esta técnica (24% LE VS 14% escleroterapia, RR 1,74, 95% CI 1,32-2,28). Não houve diferença significativa na hemorragia pós-procedimento (11,1% LE VS 8,7% escleroterapia, RR 1,29, 95% CI 0,86-1,94). Na análise de subgrupos, de acordo com o grau da DH, a dor pós-procedimento foi mais elevada com a LE apenas na DH grau II (VS DH graus I-III). Conclusões: A LE tem melhores resultados do que a escleroterapia no controlo dos sintomas, mais concretamente na resolução do prolapso e da hemorragia hemorroidária, embora a dor pós-procedimento seja uma complicação mais frequente com a LE. A recorrência é semelhante em ambos os procedimentos. Enquanto se aguarda a publicação dos resultados de estudos com novos esclerosantes, a LE deverá ser considerado o tratamento instrumental de primeira linha na DH.

Development of a warning score for early detection of colorectal anastomotic leakage: Hype or hope?

BACKGROUND: Colorectal anastomotic leakage (CAL), a severe postoperative complication, is associated with high morbidity, hospital readmission, and overall healthcare costs. Early detection of CAL remains a challenge in clinical practice. However, some decision models have been developed to increase the diagnostic accuracy of this event. AIM: To develop a score based on easily accessible variables to detect CAL early. METHODS: Based on the least absolute shrinkage and selection operator method, a predictive classification system was developed [Early ColoRectAL Leakage (E-CRALL) score] from a prospective observational, single center cohort, carried out in a colorectal division from a non-academic hospital. The score performance and CAL threshold from postoperative day (POD) 3 to POD5 were estimated. Based on a precise analytical decision model, the standard clinical practice was compared with the E-CRALL adoption on POD3, POD4, or POD5. A cost-minimization analysis was conducted, on the assumption that all alternatives delivered similar health-related effects. RESULTS: In this study, 396 patients who underwent colorectal resection surgery with anastomosis, and 6.3% (n = 25) developed CAL. Most of the patients who developed CAL (n = 23; 92%) were diagnosed during the first hospital admission, with a median time of diagnosis of 9.0 ± 6.8 d. From POD3 to POD5, the area under the receiver operating characteristic curve of the E-CRALL score was 0.82, 0.84, and 0.95, respectively. On POD5, if a threshold of 8.29 was chosen, 87.4% of anastomotic failures were identified with E-CRALL adoption. Additionally, score usage could anticipate CAL diagnosis in an average of 5.2 d and 4.1 d, if used on POD3 and POD5, respectively. Regardless of score adoption, episode comprehensive costs were markedly greater (up to four times) in patients who developed CAL in comparison with patients who did not develop CAL. Nonetheless, the use of the E-CRALL warning score was associated with cost savings of €421442.20, with most (92.9%) of the savings from patients who did not develop CAL. CONCLUSION: The E-CRALL score is an accessible tool to predict CAL at an early timepoint. Additionally, E-CRALL can reduce overall healthcare costs, mainly in the reduction of hospital costs, independent of whether a patient developed CAL.

Usefulness of serum C-reactive protein and calprotectin for the early detection of colorectal anastomotic leakage: A prospective observational study.

BACKGROUND: Colorectal anastomotic leakage (CAL) is one of the most dreaded complications after colorectal surgery, with an incidence that can be as high as 27%. This event is associated with increased morbidity and mortality; therefore, its early diagnosis is crucial to reduce clinical consequences and costs. Some biomarkers have been suggested as laboratory tools for the diagnosis of CAL. AIM: To assess the usefulness of plasma C-reactive protein (CRP) and calprotectin (CLP) as early predictors of CAL. METHODS: A prospective monocentric observational study was conducted including patients who underwent colorectal resection with anastomosis, from March 2017 to August 2019. Patients were divided into three groups: G1 - no complications; G2 - complications not related to CAL; and G3 - CAL. Five biomarkers were measured and analyzed in the first 5 postoperative days (PODs), namely white blood cell (WBC) count, eosinophil cell count (ECC), CRP, CLP, and procalcitonin (PCT). Clinical criteria, such as abdominal pain and clinical condition, were also assessed. The correlation between biomarkers and CAL was evaluated. Receiver operating characteristic (ROC) curve analysis was used to compare the accuracy of these biomarkers as predictors of CAL, and the area under the ROC curve (AUROC), specificity, sensitivity, positive predictive value, and negative predictive value (NPV) during this period were estimated. RESULTS: In total, 25 of 396 patients developed CAL (6.3%), and the mean time for this diagnosis was 9.0 ± 6.8 d. Some operative characteristics, such as surgical approach, blood loss, intraoperative complications, and duration of the procedure, were notably related to the development of CAL. The length of hospital stay was markedly higher in the group that developed CAL compared with the group with complications other than CAL and the group with no complications (median of 21 d vs 13 d and 7 d respectively; P < 0.001). For abdominal pain, the best predictive performance was on POD4 and POD5, with the largest AUROC of 0.84 on POD4. Worsening of the clinical condition was associated with the diagnosis of CAL, presenting a higher predictive effect on POD5, with an AUROC of 0.9. WBC and ECC showed better predictive effects on POD5 (AUROC = 0.62 and 0.7, respectively). Those markers also presented a high NPV (94%-98%). PCT had the best predictive effect on POD5 (AUROC = 0.61), although it presented low accuracy. However, this biomarker revealed a high NPV on POD3, POD4, and POD5 (96%, 95%, and 96%, respectively). The mean CRP value on POD5 was significantly higher in the group that developed CAL compared with the group without complications (195.5 ± 139.9 mg/L vs 59.5 ± 43.4 mg/L; P < 0.00001). On POD5, CRP had a NPV of 98%. The mean CLP value on POD3 was significantly higher in G3 compared with G1 (5.26 ± 3.58 µg/mL vs 11.52 ± 6.81 µg/mL; P < 0.00005). On POD3, the combination of CLP and CRP values showed a high diagnostic accuracy (AUROC = 0.82), providing a 5.2 d reduction in the time to CAL diagnosis. CONCLUSION: CRP and CLP are moderate predictors of CAL. However, the combination of these biomarkers presents an increased diagnostic accuracy, potentially decreasing the time to CAL diagnosis.

Polidocanol Foam Sclerotherapy Versus Rubber Band Ligation in Hemorrhoidal Disease Grades I/II/III: Randomized Trial.

BACKGROUND: Rubber band ligation and sclerotherapy are considered the office-based procedures of choice in hemorrhoidal disease. However, there are no studies comparing rubber band ligation and polidocanol foam sclerotherapy. OBJECTIVE: We aimed to evaluate the efficacy and safety of polidocanol foam sclerotherapy compared with rubber band ligation. DESIGN: This study was a randomized open-label study with 1-year follow-up. SETTINGS: The study was conducted in the colorectal unit of a tertiary hospital. PATIENTS: One hundred twenty patients with hemorrhoidal disease grades I to III were included. INTERVENTIONS: Patients were stratified by hemorrhoidal disease grade and randomly assigned (1:1) to treatment with either rubber band ligation (n = 60) or polidocanol foam sclerotherapy (n = 60). MAIN OUTCOME MEASURES: Efficacy outcomes included therapeutic success and recurrence. Safety outcomes included the occurrence of complications related to the procedures. RESULTS: Therapeutic success was not significantly different between the groups (polidocanol foam sclerotherapy 93.3% vs rubber band ligation 85.0%, p = 0.14). However, complete success rate was higher in the polidocanol foam sclerotherapy group (88.3% vs 66.7%, p = 0.009) with fewer office-based sessions (mean ± SD: 1.32 ± 0.60 vs 1.62 ± 0.76, p = 0.02). Recurrence rates were lower in the polidocanol foam sclerotherapy group (16.1% vs 41.2%, p = 0.004). Most recurrences were mild (83.3%). Complications were more frequent in the rubber band ligation group (30.0% vs 10.0%, p = 0.01) and were mostly minor (91.7%). No severe complications were observed in either group. LIMITATIONS: This study was performed in a single center, and both patients and investigators were not blinded to the treatment group. CONCLUSIONS: Both procedures are effective in the treatment of hemorrhoidal disease grades I to III. Polidocanol foam sclerotherapy was more effective than rubber band ligation when considering complete success. Patients in the polidocanol foam sclerotherapy group needed fewer treatment sessions, had lower recurrence rates, and were less likely to have complications.

ESCLEROTERAPIA CON ESPUMA DE POLIDOCANOL VERSUS LIGADURA CON BANDA DE GOMA EN LOS GRADOS I / II / III DE ENFERMEDAD HEMORROIDAL ENSAYO ALEATORIZADO: ANTECEDENTES:La ligadura con banda elástica y la escleroterapia se consideran los procedimientos de elección en el consultorio para la enfermedad hemorroidal. Sin embargo, no hay estudios que comparen la ligadura con bandas elastica y la escleroterapia con espuma de polidocanol.OBJETIVO:Nuestro objetivo fue evaluar la eficacia y seguridad de la escleroterapia con espuma de polidocanol en comparación con la ligadura con bandas elastica.DISEÑO:Estudio aleatorizado randomizado, abierto, con seguimiento de 1 año.AJUSTES:El estudio se realizó en una unidad colorrectal de un hospital terciario.PACIENTES:Se incluyeron 120 pacientes con enfermedad hemorroidal grados I a III.INTERVENCIONES:Los pacientes fueron estratificados por grado de enfermedad hemorroidal y asignados al azar (1: 1) al tratamiento con ligadura con banda elastica (n = 60) o escleroterapia con espuma de polidocanol (n = 60).PRINCIPALES MEDIDAS DE RESULTADO:Los resultados de eficacia incluyeron el éxito terapéutico y la recurrencia. Los resultados de seguridad incluyeron la aparición de complicaciones relacionadas con los procedimientos.RESULTADOS:El éxito terapéutico no fue significativamente diferente entre los grupos (escleroterapia con espuma de polidocanol 93,3% vs ligadura con banda de goma 85,0%, p = 0,14). Sin embargo, la tasa de éxito completo fue mayor en el grupo de escleroterapia con espuma de polidocanol (88,3% vs 66,7%, p = 0,009), con menos sesiones en el consultorio (media ± desviación estándar: 1,32 ± 0,60 vs 1,62 ± 0,76, p = 0,02). Las tasas de recurrencia fueron más bajas en el grupo de escleroterapia con espuma de polidocanol (16,1% vs 41,2%, p = 0,004). La mayoría de las recurrencias fueron leves (83,3%). Las complicaciones fueron más frecuentes en el grupo de ligadura con bandas elastica (30,0% vs 10,0%, p = 0,01) y fueron en su mayoría menores (91,7%). No se observaron complicaciones graves en ninguno de los grupos.LIMITACIONES:Este estudio se realizó en un solo centro y ni los pacientes ni los investigadores estaban cegados al grupo de tratamiento.CONCLUSIONES:Ambos procedimientos son efectivos en el tratamiento de la enfermedad hemorroidal grados I a III. La escleroterapia con espuma de polidocanol fue más eficaz que la ligadura con banda de goma cuando se consideró el éxito completo. Los pacientes del grupo de escleroterapia con espuma de polidocanol necesitaron menos sesiones de tratamiento, tuvieron tasas de recurrencia más bajas y menos probabilidades de tener complicaciones.

Hepatic immune-mediatedadverseeffects of immune checkpoint inhibitors: analysis of real-life experience.

INTRODUCTION AND OBJECTIVES: Immune Checkpoint Inhibitors (ICI) have shifted the paradigm of cancer therapy treatment. Despite their efficacy, ICIs may induce immune-related adverse events (irAE), which can affect various organs, namely the liver. This study intends to perform a comprehensive clinical description of the hepatic irAEs associated with ICI in a Portuguese population of a tertiary hospital centre. MATERIALS AND METHODS: A retrospective analysis of patients who developed immune-mediated liver injury (IMLI), among a cohort of patients treated with ICIs between March 15th of 2015 and December 15th of 2019 in a tertiary hospital. We used both Common Terminology Criteria for Adverse Events (CTCAE) and Drug-Induced Liver Injury Network (DILIN) criteria to define liver injury. RESULTS: Among 151 patients, eight (5.3%) patients developed liver injury grade ≥3, of which five had hepatic metastasis. As such, only 3 cases were classified as IMLI. All IMLI presented with cholestasis pattern; the median duration from ICI initiation to IMLI was 84 days and/or 4 ICI cycles; one patient registered IMLI one month after nivolumab suspension; all were treated with steroids and one was successfully submitted to ICI re-challenge; a favourable outcome was seen in all patients; the median time to hepatic biochemistries normalization was 150 days. Among 10 patients with previous hepatic conditions, only one developed liver injury grade 2. CONCLUSIONS: Clinically significant ICI-related hepatotoxicity was uncommon; Immune-mediated liver injury may present a cholestatic pattern predominance. There was a low rate of liver injury of any kind in patients with previous hepatic disease while on ICI.

Irritable Bowel Syndrome: News from an Old Disorder.

Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder, which can affect all members of a society, regardless of age, sex, race or socioeconomic status. Because of its high prevalence and chronic nature, it represents a significant economic burden. In fact, these patients have a relevant impairment of their quality of life, which limits their work productivity and daily social activities, especially when it is associated with other disorders, such as anxiety and depression. The diagnosis of IBS relies on symptom-based diagnostic criteria with normal results on a limited number of complementary tests that rule out other possible diagnoses. The aetiology of this condition is incompletely established. However, evidence suggests that it is a multifactorial disorder with several different mechanisms that have been implicated as responsible for the symptoms. Since the treatment strategy is usually based on predominant symptoms and their severity, it is important to recognise the underlying mechanisms in order to successfully relief the visceral pain and altered bowel habits. The aim of this non-systematic review of the literature was to explore the pathophysiology and treatment options of IBS, highlighting the most recent evidence, from the new Rome IV criteria to the new drug armamentarium.

A síndrome do intestino irritável é um distúrbio gastrointestinal funcional, que pode afetar todos os membros da sociedade, independentemente da idade, sexo, raça ou estrato socioeconómico. Devido à sua elevada prevalência e natureza crónica, representa um encargo económico significativo. De facto, estes doentes apresentam uma alteração relevante da sua qualidade de vida, o que limita a sua produtividade laboral e atividades de vida diárias, sobretudo quando está associada a outros distúrbios, tais como ansiedade e depressão. O diagnóstico da síndrome do intestino irritável depende de critérios diagnósticos baseados em sintomas, com resultados normais num número limitado de testes complementares que exluem outros diagnósticos possíveis. A etiologia desta doença não está completamente estabelecida. No entanto, a evidência sugere que se trata de um distúrbio multifatorial com vários mecanismos diferentes que têm sido implicados como responsáveis pelos sintomas. Visto que a estratégia terapêutica é geralmente baseada nos sintomas predominantes e sua gravidade, é importante reconhecer os mecanismos subjacentes para aliviar com sucesso a dor visceral e a alteração dos hábitos intestinais. O objetivo desta revisão literária não sistemática consistiu em explorar a fisiopatologia e opções terapêuticas disponíveis para a síndrome do intestino irritável, realçando a evidência mais recente, desde os novos critérios Roma IV até ao novo arsenal farmacológico.

Portuguese Society of Gastroenterology Consensus on the Diagnosis and Management of Hemorrhoidal Disease.

Hemorrhoidal disease (HD) is a frequent health problem with considerable repercussions on patients' quality of life. However, much of the clinical practice related to HD is based on knowledge without scientific evidence and supported largely by empirical experience of the physician who deals with this pathology. As in other countries, the goal of this consensus is to establish statements supported by solid scientific evidence and whose purpose will be to standardize and guide the diagnosis and management of HD both in the general population and in some particular groups of patients.

A doença hemorroidária é uma patologia prevalente com repercussões consideráveis na qualidade de vida dos doentes. No entanto, muita da prática clínica relacionada com a doença hemorroidária é baseada em conhecimentos sem evidência científica e apoiada largamente por uma experiência empírica por parte do médico que lida com esta patologia. À semelhança do que tem sido feito noutros países, o objetivo deste consenso foi estabelecer statements suportados por evidência científica sólida e cuja finalidade será o de uniformizar e orientar o diagnóstico e tratamento da doença hemorroidária quer na população em geral quer em grupos particulares de doentes.

Preoperative Enteral Nutrition and Surgical Outcomes in Adults with Crohn's Disease: A Systematic Review.

BACKGROUND AND AIM: Enteral nutrition (EN) is applicable to adult Crohn's disease (CD) in treating malnutrition and in inducing remission - here as a less effective alternative than corticosteroids. The purpose of this review is to determine whether preoperative EN impacts postoperative complications of adult CD, either by means of nutritional or therapeutic effects. SUMMARY: A systematic review of English written full-text research articles published between January 1990 and November 2017, including adult patients undergoing abdominal surgery for complicated CD after EN, was performed. Four studies out of 22 were selected, all of which institutional, retrospective, case-control cohorts, one classified as "good quality" and three as "poor quality," as rated by the Newcastle-Ottawa Scale. The application of inclusion and exclusion criteria resulted in a non-intentional absence of studies referring to supplemental EN among those reviewed. The reduced number of heterogeneous eligible studies impeded meta-analysis. In all studies, exclusive EN (EEN) was used and well tolerated, allowing to defer or even avoid surgery altogether, improving patients' global state. The two studies with the greatest number of patients found preoperative EEN to be an independent factor against infectious and non-infectious complications in 219 patients and against anastomotic leaks or abscesses in 38 patients. Also, in univariate analysis, EEN was found to increase preop-erative immunosuppressant-free intervals and to protect against anastomotic dehiscences, intra-abdominal abscesses, surgical wound infections, ileus, stomas, and reoperations in the largest study; in another study it was related to fewer intra-abdominal septic complications. KEY MESSAGES: All reviewed studies are retrospective and, consequently, of limited relevance. Nonetheless, all of them call the attention of the scientific community to the potential benefits of preoperative EEN on postoperative outcomes in adult CD, calling for prospective multi-institutional studies and randomized controlled trials.

INTRODUÇÃO E OBJETIVO: No adulto com doença de Crohn (DC) a nutrição entérica (NE) é aplicável como terapáutica da desnutrição ou como alternativa, menos eficaz, aos corticoides, para indução de remissão. O objetivo desta revisão é determinar se a NE pré-operatória tem impacto nas complicações pós-operatórias, seja pelo efeito nutricional seja pelo terapáutico. SUMÁRIO: Foi realizada uma revisão sistemática dos artigos de investigação que incluíssem doentes adultos submetidos a cirurgia abdominal por DC complicada, após NE, redigidos em inglás e publicados entre janeiro de 1990 e novembro de 2017. De 22 estudos foram selecionados quatro institucionais e retrospetivos de coorte, um de "fraca qualidade" e trás de "pobre qualidade" pela "Newcastle-Ottawa Scale". Nos estudos revistos foi utilizada NE exclusiva (NEE) já que, não intencionalmente, os estudos com NE suplementar reuniram critérios de exclusão. O pequeno número e a heterogeneidade dos estudos elegíveis impossibilitaram uma meta-análise. A NEE foi utilizada e bem tolerada em todos os estudos, e permitiu melhorar o estado global dos doentes e protelar ou mesmo evitar a cirurgia. Nos dois estudos com maior número de doentes, a NEE pré-operatória foi um fator independente contra deiscáncias de sutura e abcessos em 219 doentes, e contra complicações infeciosas intra-abdominais em 38. Em análise univariada também se verificou que, no maior estudo, a NEE aumentou o intervalo pré-operatório livre de imunossupressores e foi protetora contra deiscáncias anastomóticas, abscessos intra-abdominais, infeções da ferida operatória, ileus, estomas e reoperações; noutro estudo menores correlacionou-se com menos complicações infeciosas intra-ab abdominais. MENSAGENS-CHAVE: Todos os estudos revistos são retrospetivos e, consequentemente, de relevância limitada. No entanto, todos chamam a atenção da comunidade científica para os potenciais benefícios da NEE préoperatória nos resultados pós-operatórios dos adultos com DC e para a necessidade de estudos prospetivos multi-institucionais e de ensaios clínicos randomizados.

Miniprobe endoscopic ultrasonography for the diagnosis of colon hemangiolymphangioma

Hemangiolymphangioma is a very rare benign vascular tumor that affects the gastrointestinal tract in less than 1% of cases. We present the case of an asymptomatic 52-year-old female referred for endoscopic colorectal cancer screening. A sub-epithelial pediculated polypoid lesion in the splenic angle of the colon was identified. An endoscopic ultrasonography with a miniprobe was performed, which identified an anechoic lesion in the submucosal layer. Surgery was performed and the histologic findings were compatible with two hemangiolymphangioma lesions. This is one of the few cases reported in the literature of hemangiolymphangioma diagnosed by miniprobe endoscopic ultrasonography and the first to describe two lesions in the same patient

3D echoendoscopy and miniprobes for rectal cancer staging

Background: rectal cancer staging using rigid probes or echoendoscopes has some limitations. The aim of the study was to compare rectal cancer preoperative staging using conventional endoluminal ultrasonography with three-dimensional endoscopic ultrasonography and miniprobes. Materials and methods: sixty patients were included and evaluated with: a) a conventional echoendoscope (7.5 and 12 MHz); b) miniprobes (12 MHz); and c) the Easy 3D Freescan software for three-dimensional endoscopic ultrasonography. The reference or gold standard was conventional endoluminal ultrasonography in all cases and pathological assessment for those without preoperative therapy. The differences in T and N staging accuracy in both longitudinal and circumferential extension were evaluated. Results: with regard to T staging, conventional endoluminal ultrasonography had an accuracy of 85% (compared to pathological analysis), and the agreement between miniprobes vs conventional endoluminal ultrasonography (kappa = 0.81) and three-dimensional endoscopic ultrasonography vs conventional endoluminal ultrasonography (k = 0.87) was significant. In addition, miniprobes had an accuracy of 82% and three-dimensional endoscopic ultrasonography had a higher accuracy (96%). With regard to N staging, conventional endoluminal ultrasonography had an accuracy of 91% with a sensitivity of 78%. However, the agreement between miniprobes and conventional endoluminal ultrasonography and three-dimensional endoscopic ultrasonography and conventional endoluminal ultrasonography (k = 0.70) was lower. Interestingly, miniprobes had a lower accuracy of 81% whereas three-dimensional endoscopic ultrasonography had an accuracy of 100% without any false negative. No false positives were observed in any of the techniques. Accuracy for T and N staging was not influenced by longitudinal or circumferential extensions of the tumor in all types of endoscopic ultrasonography analyzed. Conclusions: miniprobes and especially three-dimensional endoscopic ultrasonography may be relevant during rectal cancer staging

Interestingly, miniprobes had a lower accuracy of 81% whereas three-dimensional endoscopic ultrasonography had an accuracy of 100% without any false negative. No false positives were observed in any of the techniques. Accuracy for T and N staging was not influenced by longitudinal or circumferential extensions of the tumor in all types of endoscopic ultrasonography analyzed. CONCLUSIONS: miniprobes and especially three-dimensional endoscopic ultrasonography may be relevant during rectal cancer staging.

The role of endoscopic ultrasound in a case of lung cancer with jaundice.

Lung cancer is one of the major causes of death in the world. Small cell carcinoma is the most aggressive type and can spread rapidly. The association of a small cell carcinoma with hepatic hilar metastasis and biliary obstruction is rare. Endoscopic ultrasound allows the aspiration of a cytology sample from adenopathies for diagnostic purpose. We present the case of a patient with lung cancer, with lymph node metastasis to the hepatic hilum and extrinsic biliary tree compression. Endoscopic ultrasound allowed the definitive diagnosis of hepatic hilar metastasis of a lung small cell carcinoma. To the author's knowledge it was the first time that endoscopic ultrasound was used for the diagnosis of hepatic hilar lymph node metastasis of lung cancer.

Mediastinal Mass in a Patient with Colorectal Cancer: A Diagnostic Challenge.

The differential diagnosis of mediastinal masses involves many benign and malignant conditions, such as lymphadenopathies and cystic lesions. Metastatic mediastinal adenopathies are usually due to lung, esophagus, and stomach cancer and, rarely, due to colorectal cancer. Gastrointestinal duplication cysts are uncommon inherited lesions usually diagnosed during childhood and may involve the esophagus in 20% of cases. In adults, they are usually asymptomatic and diagnosed incidentally. We report the case of a 54-year-old male who recently underwent sigmoidectomy due to an obstructive colon adenocarcinoma. Staging computed tomography scan showed a hypodense lesion in the posterior mediastinum suggestive of metastatic adenopathy. Endoscopic ultrasound revealed a homogeneous and hypoechogenic lesion with intramural location in the upper esophagus, suggestive of a duplication esophageal cyst. Given the oncologic background and to exclude metastatic disease, endoscopic ultrasound-guided fine needle aspiration was performed, and a mucinous fluid was aspirated. The cytologic examination supported the ultrasonographic diagnostic hypothesis. This case highlights the role of endoscopic ultrasound in the differential diagnosis of mediastinal masses, particularly in oncologic patients, in order to rule out more ominous lesions.

O diagnóstico diferencial das massas mediastínicas inclui diversas patologias benignas e malignas, tais como linfadenopatias e lesões císticas. As adenopatias mediastínicas metastáticas são habitualmente devidas ao cancro do pulmão, esófago e estômago, e mais raramente ao cancro colorretal. Os cistos de duplicação gastrointestinais são lesões congénitas diagnosticadas habitualmente durante a infância e podem envolver o esófago em cerca de 20% dos casos. Nos adultos, são frequentemente assintomáticos e diagnosticadas acidentalmente. Apresentamos o caso de um homem de 54 anos recentemente submetido a sigmoidectomia por adenocarcinoma estenosante do sigmóide. A tomografia computorizada de estadiamento mostrou uma lesão hipodensa no mediastino posterior, sugestiva de adenopatia metastática. A ultrassonografia endoscópica revelou uma lesão homogénea e hipoecogénica na dependência da parede do esófago torácico, sugestiva de um cisto de duplicação esofágico. Dado o contexto oncológico e para excluir doença metastática, foi realizada punção aspirativa com agulha fina tendo-se aspirado um fluido mucinoso. O exame citológico confirmou a hipótese diagnóstica ultrassonográfica. Este caso destaca o papel da ultrassonografia endoscópica no diagnóstico diferencial das massas mediastínicas, particularmente em doentes oncológicos, no sentido de excluir lesões mais graves.

Type 2 Autoimmune Pancreatitis: A Challenge in the Differential Diagnosis of a Pancreatic Mass.

INTRODUCTION: Autoimmune pancreatitis is a rare entity of unknown etiology that can mimic pancreatic cancer and whose diagnosis involves clinical, serological, imagiological, and histological findings. There are two types of autoimmune pancreatitis: type 1, in which the pancreas is involved as one part of a systemic immunoglobulin G4-related disease, and type 2, generally without immunoglobulin G4-positive cells and without systemic involvement. CASE: We report the case of a 45-year-old female, who underwent an abdominal magnetic resonance imaging for etiological study of a solid liver lesion, which revealed a tail pancreatic mass. Laboratory analyses showed normal levels of immunoglobulin G4 and negative antinuclear antibodies. Endoscopic ultrasound revealed a homogeneous and hypoechogenic lesion in the pancreatic tail with a "sausage-like" appearance. Endoscopic ultrasound-guided fine needle aspiration was inconclusive and the patient underwent a laparoscopic distal pancreatectomy. Histopathology examination confirmed the diagnosis of type 2 autoimmune pancreatitis. CONCLUSION: This case highlights the challenge in the diagnostic approach of a pancreatic mass, particularly in distinguishing benign from malignant disease.

Introdução: A pancreatite autoimune é uma entidade rara, de etiopatogenia desconhecida, que pode simular cancro do pâncreas e cujo diagnóstico envolve a integração de dados clínicos, serológicos, imagiológicos e histológicos. Descrevem-se dois tipos de pancreatite autoimune: tipo 1, cujo envolvimento pancreático integra o espetro das doenças associadas à imunoglobulina G4, e tipo 2, geralmente sem evidência de células imunoglobulina G4 positivas e sem manifestações sistémicas. Caso: Apresentamos o caso de uma mulher de 45 anos, submetida a ressonância magnética abdominal para esclarecimento etiológico de lesão nodular hepática que revelou uma massa na cauda do pâncreas. Analiticamente apresentava imunoglobulina G4 normal e anticorpos antinucleares negativos. A ultrassonografia endoscópica revelou uma lesão homogénea e hipoecogénica na cauda pancreática com morfologia "em salsicha". A punção aspirativa por agulha fina foi inconclusiva tendo a doente sido submetida a pancreatectomia distal por via laparoscópica. O exame histopatológico confirmou o diagnóstico de pancreatite autoimune tipo 2. Conclusão: Este caso destaca o desafio na abordagem diagnóstica da massa pancreática, particularmente na diferenciação entre patologia benigna e maligna.
