RESUMO
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.

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.

PURPOSE: To characterize colon and rectum walls, pericolic and perirectal spaces, using endoscopic ultrasonography miniprobes. METHODS: Sixty individuals (50% males), aged 18-80, were included. Using 12 and 20 MHz endoscopic ultrasonography miniprobes, all different colon segments (ascending, transverse, descending, sigmoid) and rectum were evaluated according to the number and thickness of the different layers in intestinal wall, to the presence and (largest) diameter of vessels in the submucosa and of peri-intestinal nodes. RESULTS: The 20 MHz miniprobe identified a higher number of layers than the 12 MHz miniprobe, with medians of 7 and 5 respectively (p < 0.001). The rectal wall (p = 0.001), its muscularis propria (p < 0.001) and mucosa (p = 0.01) were significantly thicker than the different segments of the colon, which had no significant differences between them. Patients aged 41-60 presented thicker colonic wall and muscularis propria in descending (p = 0.001 and p = 0.004) and rectum (p = 0.01 and p = 0.01). Submucosal vessels were identified in 30% of individuals in descending and rectum, and in 12% in ascending. Adenopathies were observed in 9% of the colon segments and 5% in rectum. CONCLUSIONS: A higher frequency enabled the identification of a higher number of layers. Rectal wall is thicker than the one from all the segments of the colon and there are no differences between these, namely in the ascending colon. Moreover, periintestinal adenopathies were rarely identified but present in asymptomatic individuals. All together, these results describe for the first time features which are relevant during staging and therapeutic management of colonic lesions.

Duodenal gastrointestinal stromal tumors (GISTs) are a very rare condition. The pre-operative diagnosis can be a challenge but it is very important because GISTs have singularities that differ from other tumors and their location in the duodenum itself can have a major role in the choice of the surgical approach. We present two cases of duodenal GISTs where endoscopic ultrasound had a single role in their management, namely allowing the possibility to obtain material for immunocytochemical pre-operative diagnosis and regarding the precise relation to the papilla of Vater. The patients were operated and histological examination confirmed the diagnosis in both cases.

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.
RESUMO
Rectal duplication cysts account for 4% of all duplications of the alimentary tract. Presentation in adulthood is rare. An asymptomatic 54-year-old man was referred for endoscopic colorectal cancer screening. A bulging mass covered by normal mucosa was identified in the rectum. Endoscopic ultrasonography (EUS) with fine needle aspiration (FNA) was made for a diagnosis of rectal duplication cyst. The patient was operated and the diagnosis was confirmed. The diagnosis of the rectal duplication cyst is a challenge. EUS may have a singular role when identifying a muscular layer, because this is the only absolutely necessary criterion for the diagnosis. FNA by EUS may eventually identify colorectal and/or heterotypic epithelium that are the other diagnostic criteria of the duplication cyst.
RESUMO
BACKGROUND AND OBJECTIVES: Due to the increasing use of endoscopic techniques for colon cancer resection, pretreatment locoregional staging may gain critical interest. The use of endoscopic ultrasonography (EUS) miniprobes in this context has been seldom reported. Our aim was to determine the accuracy of EUS miniprobes for colon cancer staging. MATERIALS AND METHODS: Forty patients with colon cancer (2 in the cecum, 9 in the ascending colon, 5 in the transverse colon, 5 in the descending colon, and 19 in the sigmoid colon) were submitted to staging using 12 MHz EUS miniprobes. EUS and the anatomopathological results were compared with regard to the T and N stages. It was assessed if the location, longitudinal extension, or circumferential extension of the tumor had any influence on the accuracy in EUS staging. RESULTS: Tumor staging was feasible in 39 (98%) patients except in one case with a stenosing tumor (out of 6). Globally, T stage was accurately determined in 88% of the cases. In the assessment of the presence or absence of lymph node metastasis, miniprobes presented an accuracy of 82% with a sensitivity of 67%. These results were neither affected by the location nor by the longitudinal or circumferential extension of the tumor. CONCLUSIONS: EUS miniprobes may play an important role in assessing T and N stages in colon cancer and may represent an incentive to the research of new therapeutic areas for this disease.
