RESUMO
Las lesiones de la cavidad oral corresponden a un hallazgo frecuente y muchas veces difíciles de diagnosticar. Su correcto reconocimiento podría ser clave en detectar patologías que podrían cambiar el pronóstico del paciente. El objetivo de esta revisión es describir una clasificación de las lesiones de la cavidad oral que permita ayudar al diagnóstico en la práctica clínica. Para esto, se detallan y se describen las lesiones, orientando al diagnóstico y a la necesidad de biopsiar. Para simplificar la orientación diagnóstica, las lesiones se clasifican en 2 grandes grupos: tumorales y no tumorales. Las lesiones no tumorales se subdividen en lesiones de la mucosa oral y lesiones de la lengua.
Lesions of the oral cavity are frequent and often difficult to diagnose. However, correct recognition could change the patient's prognosis. This review aims to describe a classification of oral mucosa lesions, to help the diagnosis in clinical practice. The lesions are described for this, guiding the diagnosis and the need for biopsy. To simplify the diagnostic orientation, the lesions are classified into two groups: tumor and non-tumor lesions. Non-tumor lesions are subdivided into lesions of the oral mucosa and lesions of the tongue.

Introducción: Las leucoplaquias laríngeas (LL) pueden corresponder a lesiones precancerosas. La aproximación diagnóstica es endoscópica y en caso de persistir, se debe estudiar con biopsia. Objetivo: Describir las características biodemográficas, clínicas, endoscópicas, histológicas y evolutivas de pacientes diagnosticados con leucoplaquias glóticas. Material y Método: Estudio prospectivo no-concurrente de pacientes diagnosticados con leucoplaquias glóticas en la Unidad de Voz del Departamento de Otorrinolaringología de la Pontificia Universidad Católica de Chile, entre 2012 y 2019. Resultados: Se incluyeron 29 pacientes, 65,5% hombres, con edad promedio de 61 años y seguimiento promedio de 21,1 meses. El principal motivo de consulta fue disfonía, en un 86,2% de los casos. El 38% presentó compromiso del pliegue vocal (PV) izquierdo, 24,1% derecho, 24,1% bilateral y 13,8% bilateral incluyendo comisura anterior. El 41,4% de las lesiones comprometían más del 50% del PV y 68% presentaba una onda mucosa alterada en la estroboscopia. Un 89,7% requirió biopsia, identificando carcinoma en 26,9%, displasia en 34,6% y otro diagnóstico en 38,5%. El 25,9% presentó recurrencias, del cual 28,6% progresó a cáncer. Se identificó asociación significativa en un análisis bivariado entre la edad (p = 0,030) y compromiso mayor al 50% del PV (p = 0,016) con displasia de alto riesgo o cáncer. En el análisis multivariado, solo la edad mostró ser significativa (p = 0,038; OR 1,27; IC 95% 1,01-1,59). Conclusión: El estudio de las LL es esencial para el diagnóstico precoz de cáncer laríngeo. La edad y el compromiso mayor al 50% del PV en la estroboscopia podría predecir un riesgo mayor de displasia de alto riesgo o cáncer.
Introduction: Laryngeal leukoplakia (LL) may correspond to precancerous lesions. The diagnostic approach is endoscopic, and if LL persist, a biopsy should be performed. Aim: To describe the biodemographic, clinical, endoscopic, histological, and developmental characteristics of patients diagnosed with glottic leucoplakia. Material and Method: Prospective non-concurrent study of patients diagnosed with glottic leukoplakia in the Voice Unit at the Otolaryngology Department of the Pontificia Universidad Catolica de Chile, between 2012 and 2019. Results: Twenty-nine patients were included, 65.5% men, with an average age of 61.7 years, and average follow-up of 21.1 months. Dysphonia was the chief complaint, present in 86.2% of the cases. The left vocal fold (VF) was involved in 38.0%, right in 24.1%, bilateral in 24.1%, and bilateral including anterior commissure in 13.8%. Only 41.4% compromised over 50% of the VF and 68.0% presented an altered mucosal wave in the videostroboscopy. A biopsy was performed in 89.7%, identifying carcinoma in 26.9%, dysplasia in 34.6% and other diagnosis in 38.5%. During follow-up 25.9% recurred, of which 28.6% progressed to cancer. A significant association was found in the bivariate analysis between age (p = 0.030) and extension over 50% of the VF (p = 0.016) with high-risk dysplasia or cancer. In the multivariate analysis only, the age was found to be significative (p = 0.038; OR 1.27; CI 95% 1.01-1.59). Conclusions: A thorough evaluation is essential in LL, favoring an early diagnosis for laryngeal cancer. Age and an involvement greater than 50% of the VF in the videostroboscopy could predict an increased possibility for high-risk dysplasia or cancer.

La obstrucción laríngea inducible se ha descrito como un trastorno de la respiración que se presenta, habitualmente, como dificultad respiratoria aguda por aducción anormal de los pliegues vocales, típicamente, durante la inspiración. Es más frecuente en mujeres y adultos, que en adolescentes. Es difícil estimar la incidencia exacta dada la heterogeneidad de los criterios diagnósticos y nomenclatura, asociado al frecuente subdiagnóstico de esta entidad. Por ello, en la literatura se ha reportado la prevalencia de acuerdo con las subpoblaciones de pacientes, describiendo que alrededor de un 2,8% de los pacientes que consultan en el servicio de urgencia por disnea podría corresponder a esta patología. El diagnóstico es eminentemente clínico, con confirmación mediante laringoscopia flexible. Se apoya en exámenes de función respiratoria, especialmente para descartar otras patologías pulmonares que expliquen el cuadro. El tratamiento es sencillo y, suele ser exitoso, tanto en situaciones agudas como crónicas. Sin embargo, se ha descrito, frecuentemente, un retraso en el diagnóstico, debido a desconocimiento de esta patología.
Induced laryngeal obstruction has been described as a respiratory disorder, usually presenting as an acute respiratory distress due to abnormal adduction of the vocal folds, typically during inspiration. It is more frequent in women and adults, than adolescents. It is difficult to estimate its exact incidence given the heterogeneity of the diagnostic criteria and nomenclature, together with its common underdiagnosis. Hence, studies have reported its prevalence according to the subpopulations within this entity, with a prevalence of 2.8% in patients who consult in the emergency room for dyspnea. The diagnosis is based upon clinical presentation, confirmed by flexible laryngoscopy, and supported by respiratory function exams to rule out other pulmonary diseases with similar symptoms. Its treatment is simple and usually successful, in both acute and chronic situations. However, a delay in the diagnosis has been frequently described, due to unawareness of this disorder.

INTRODUCTION: The incidence of synchronous RCC and colorectal cancer is heterogeneous ranging from 0.03 to 4.85%. Instead, only one case of huge colon carcinoma and renal angiomyolipoma was reported. The treatment of synchronous kidney and colorectal neoplasm is, preferably, synchronous resection. Currently, laparoscopic approach has shown to be feasible and safe, and it has become the gold standard of synchronous resection due to advantages of minimally invasive surgery. We presented a case synchronous renal neoplasm and colorectal cancer undergone simultaneous totally robotic renal enucleation and rectal resection with primary intracorporeal anastomosis. As our knowledge, this is the first case in literature of simultaneous robotic surgery for renal and colorectal tumor. CASE PRESENTATION: A 53-year-old woman was affected by recto-sigmoid junction cancer and a solid 5 cm left renal mass. We performed a simultaneous robotic low anterior rectal resection and renal enucleation. Total operative time was 260 min with robotic time of 220 min; estimated blood loss was 150 ml; time to flatus was 72 h, and oral diet was administered 4 days after surgery. The patient was discharged on the eighth post-operative day without peri- and post-operative complication. The definitive histological examination showed a neuroendocrine tumor pT2N1 G2, with negative circumferential and distal resection margins. Renal tumor was angiomyolipoma. At 23 months follow-up, the patient is recurrence free. DISCUSSION AND CONCLUSION: As our knowledge, we described the first case in literature of simultaneous robotic anterior rectal resection and partial nephrectomy for treatment of colorectal tumor and renal mass. Robotic rectal resection with intracorporeal anastomosis surgery seems to be feasible and safe even when it is associated with simultaneous partial nephrectomy. Many features of robotic technology could be useful in combined surgery. This strategy is recommended only when patients' medical conditions allow for longer anesthesia exposure. The advantages are to avoid a delay treatment of second tumor, to reduce the time to start the post-operative adjuvant chemotherapy, to avoid a second anesthetic procedure, and to reduce the patient discomfort. However, further studies are needed to evaluate robotic approach as standard surgical strategy for simultaneous treatment of colorectal and renal neoplasm.

RESUMEN Una de las manifestaciones clínicas del virus papiloma humano (VPH) es la papilomatosis respiratoria recurrente (PRR), que se caracteriza por la proliferación de lesiones epiteliales verrucosas recurrentes en la mucosa respiratoria, pudiendo progresar a obstrucción de vía aérea o presentar transformación maligna. El tratamiento de primera línea quirúrgico, pero dada su alta recurrencia ha tomado peso el tratamiento adyuvante, como la vacuna tetravalente contra VPH. Sin embargo, existe controversia respecto a su eficacia. El objetivo de esta revisión es analizar la efectividad de la vacuna contra VPH como tratamiento adyuvante de la PRR, para lo cual hicimos una revisión de la literatura sobre la efectividad de la vacuna tetravalente contra VPH para PRR, realizando una búsqueda en diversas fuentes: Pubmed, MEDLINE, EMBASE, Cochrane, Google Scholar y Epistemonikos. Se seleccionaron los estudios que responden a la pregunta y se analizaron los datos de los estudios primarios. Se encontraron cinco estudios primarios no aleatorizados, todos a favor de la vacuna como tratamiento. Concluimos con baja certeza de evidencia, que la vacuna es posiblemente efectiva para pacientes con PRR en disminuir el número de recurrencias, aumentar el intervalo entre cirugías, lograr remisión completa o parcial de la enfermedad y aumentar significativamente los títulos de anticuerpos anti-VPH.
ABSTRACT A clinical manifestation of human papillomavirus (HPV) is recurrent respiratory papillomatosis (RRP), characterized by the proliferation of recurrent verrucous epithelial lesions in the respiratory mucosa, which may progress to airway obstruction or malignant transformation. First-line treatment is surgery, but given its high recurrence the use of adjuvant therapy, such as the quadrivalent vaccine, has gained importance. However, there is controversy regarding its effectiveness. To analyze the effectiveness of the HPV vaccine as an adjuvant treatment for RRP a review of the literature on the effectiveness of HPV tetravalent vaccine for RRP was performed by searching databases such as Pubmed, MEDLINE, EMBASE, Cochrane, Google Scholar and Epistemonikos. We selected the studies that answered the question and analyzed the data from all of which supported the vaccine as treatment. None were randomized controlled trials. We conclude, with low certainty of evidence, that the vaccine is possibly effective for RRP in decreasing the number of recurrences, increasing the intersurgical interval, achieving complete or partial remission of disease and significantly increasing anti-HPV antibodies.

Introduction: Vocal cord cysts are a relatively frequent cause of dysphonia. Their origin is still controversial, and their diagnosis and management continue to be a clinical challenge. Aim: To describe and analyze the clinical characteristics of vocal cord cysts in our series of patients. Material and method: Descriptive retrospective study of patients with diagnosis of vocal cord cyst attended in our center between June 2012 and December 2015. Results: 44 patients had the diagnosis of vocal cord cyst, which represents 4.32% of the patients that attended our Voice Center during that period. Most of the patients were adults, and among them 68.29% corresponded to women. 34.1% of the patients were submitted to surgical treatment with microphonosurgery technique. 75% of the surgical patients presented an improvement in the pattern of the videolaryngostroboscopic mucosal wave. All the patients in which pre and postsurgical subjective voice assessment polls were available, showed a significant voice improvement. Conclusion: Vocal cord cysts are lesions that affect both children and adults. The videolaryngostroboscopy evaluation is key in the diagnosis of these lesions, and the surgical treatment with microphonosurgery is effective in terms of anatomical and functional vocal results.

Los tumores condroides de la laringe son poco frecuentes, y generalmente se ubican en el cartílago cricoides. El tratamiento de elección es quirúrgico, con buen pronóstico general. Se presenta el caso de un hombre de 60 años con historia de disfonía. El estudio nasofaringolaringofibroscópico revela una masa laríngea supraglótica. Las imágenes son compatibles con una lesión del cartílago tiroides. La biopsia obtenida por microlaringoscopía directa informa tumor compatible con condroma. Se realiza una resección completa de la masa por abordaje externo, la biopsia corrobora el diagnóstico de tumor condroide de bajo grado. Se describe esta patología mediante revisión bibliográfica.
Chondroid tumors of the larynx are uncommon, and usually located in the cricoid cartilage. Surgery is the treatment of choice, with good prognosis in general. We report the case of a 60-year-old man consulting for dysphonia. The nasopharyngolaryngoscopy showed a supraglottic laryngeal mass. The images were compatible with a thyroid cartilage lesion. The biopsy sample obtained by direct microlaryngoscopy was consistent with a condroma. A complete excision of the lesion was performed by external approach and the biopsy confirmed the diagnosis of a low grade chondroid tumor. We present a review of chondroid tumors of the larynx based on available literature.

Introducción: La laringitis fúngica es una patología poco planteada en pacientes inmunocompetentes, sin embargo se debería tener en consideración en el diagnóstico diferencial de leucoplaquias en estos pacientes, más aún con factores predisponentes como reflujo faringolaríngeo, tabaquismo crónico y/o uso de corticoides. Objetivo: Presentar una serie de casos de pacientes inmunocompetentes con diagnóstico clínico de laringitis fúngica y tratamiento antimicótico empírico. Describir la asociación con factores predisponentes claves. Material y método: Estudio retrospectivo que incluyó a 11 pacientes con diagnóstico clínico de laringitis fúngica por correlación de la clínica, factores predisponentes y hallazgos en la videoestroboscopía laríngea (leucoplaquias múltiples en los pliegues vocales) sumado a la respuesta a tratamiento empírico con fluconazol oral. Se realizó además una revisión de la literatura disponible hasta el año 2015. Resultados: Todos los diagnósticos fueron clínicos correlacionando síntomas con hallazgo de leucoplaquias características en la laringe. El principal factor asociado fue el reflujo faringolaríngeo (91%) seguido por uso de corticoides (55%). Todos los pacientes fueron tratados con un esquema empírico de fluconazol oral por 14-21 días. El 100% de los pacientes respondió de forma exitosa al uso de este fármaco con remisión de los síntomas y de las lesiones laríngeas. Conclusión: El diagnóstico clínico y tratamiento con fluconazol oral como tratamiento de primera línea generarían buena tasa de respuesta, siempre que se correlacionen los síntomas y signos del paciente con los hallazgos encontrados en la laringe.
Introduction: The fungal laryngitis is an unusual disease in immunocompetent patients, however should take into consideration in the differential diagnosis of leukoplakias, especially in patients with predisposing factors such as pharyngolaryngeal reflux, use of inhaled, oral or intravenous corticosteroids. Aim: Describe a series of cases of fungal laryngitis in immunocompetent patients with clinical diagnosis and empirical antifungal treatment. In addition, finding the association with predisposing factors keys. Material and method: Retrospective study of 11 patients with diagnosis of fungal laryngitis according to clinical presentation, predisposing factors and findings in the laryngeal videostroboscopy (vocal folds leukoplakias) joined the response to empirical treatment with oral fluconazole. Also an extensive literature review was conducted until 2015. Results: The main predisposing factor was the pharyngolaryngeal reflux (91%) followed by use of corticosteroids (55%). All patients were treated empirically with fluconazole for 14-21 days. 100% of patients responded successfully, with remission of symptoms and laryngeal lesions. Conclusion: Clinical diagnosis and treatment with fluconazole as first-line treatment generate good response rate, provided that the patient's symptoms and signs with the findings in the larynx are correlated.

Introducción: El manejo inicial de la parálisis cordal unilateral incluye la observación en espera de la recuperación de la movilidad o la compensación, terapia fonoaudiológica o inyección de medialización temporal para llevar la cuerda a una posición más favorable para el cierre glótico. Este procedimiento puede realizarse en pabellón, o vía percutánea en paciente despierto. Existen varias opciones, siendo el ácido hialurónico (Restylane®) uno de los más usados. Objetivo: Revisar la experiencia pionera en el país en la inyección de medialización de cuerda vocal con ácido hialurónico en el manejo de la parálisis cordal unilateral. Material y método: Estudio retrospectivo, que incluyó a 15 pacientes con insuficiencia glótica a los que se les realizó una inyección percutánea con ácido hialurónico. Se evaluó la calidad de la voz pre y posprocedimiento (VRQOL), tolerancia al procedimiento y complicaciones. Resultados: El 100% de los pacientes mostró cambios significativos en el VRQOL, con un cambio promedio pre y post de 37%. El procedimiento fue bien tolerado en el 93%. No se produjeron incidentes durante la inyección ni tampoco posteriores. Conclusión: La inyección de medialización es un procedimiento bien tolerado, seguro y sencillo, que permite mejoras significativas en la calidad vocal. El ácido hialurónico es seguro y eficaz para la inyección de medialización.
Introduction: Initial treatment options for unilateral vocal fold paralysis include observation for spontaneous return of function or compensation, voice therapy to stimulate recovery of motion or function, or temporary vocal fold injection medialization to improve glottic closure. Temporary injection medialization can be performed under general anesthesia or in the awake-patient setting with local anesthesia. There are different options of temporary injection materials, being hyaluronic acid (Restylane®) one of the most popular. Aim: To review our pioneer experience in Chilewith the use of temporary vocal fold injection with hyaluronic acid in the initial management of unilateral vocal fold paralysis. Material and method: Retrospective study involving 15 patients with glottic insufficiency, who underwent percutaneous vocal fold injection medialization with hyaluronic acid. Pre and post procedure quality of voice (VRQOL), tolerance to the procedure, and complications were evaluated. Results: All patients showed significant changes in VRQOL, with a 37% average improvement. The procedure was well tolerated in 93%. No incidents occurred during injection orlater. Conclusions: The temporary vocal fold injection medialization is a well-tolerated, safe and simple procedure that allows significant short-term improvements in vocal quality of patients. Hyaluronic acid is a safe and effective material for temporary vocal foldinjection medialization.

Introduction: Thyroid surgery rates have tripled over the past 3 decades. Currently, the main postoperative complications of this surgery are vocal fold paralysis because of recurrent laryngeal nerve dysfunction and hypocalcemia. Case report: We report the case of a 58 years old woman who presented with persistent dysphonia post total thyroidectomy. Laryngeal videostroboscopy evidenced unilateral vocal fold paralysis. We performed a percutaneous injection laryngoplasty with hyaluronic acid achieving significant improvement in voice. Conclusions: Percutaneous injection laryngoplasty with hyaluronic acid is a safe and effective procedure in the management of post thyroidectomy vocal cord paralysis.
Introducción: La tasa de cirugía tiroidea se ha triplicado en las últimas 3 décadas. Dentro de sus complicaciones se encuentra la parálisis de cuerda vocal unilateral secundaria a lesión transitoria o permanente del nervio laríngeo recurrente, lo que se presenta clínicamente como disfonía. Caso clínico: Paciente de 58 años, post tiroidectomía total evoluciona con disfonía persistente. Videoestroboscopia evidencia parálisis cuerda vocal izquierda en posición paramediana, con hiato fonatorio longitudinal amplio. Se maneja con laringoplastía por inyección con ácido hialurónico a cuerda vocal paralítica, logrando mejora significativa de voz. En videoestroboscopia de control al 7º día se evidencia cuerda vocal izquierda en línea media, con borde libre recto, sin presencia de hiato al fonar. Conclusiones: La laringoplastía por inyección percutánea con ácido hialurónico es un procedimiento seguro y eficaz para el tratamiento de la disfonía secundaria a parálisis cordal unilateral post cirugía tiroidea.

OBJECTIVE: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology is an effective tool to diagnose pancreatic ductal adenocarcinoma (PDA). Standard morphological criteria are usually reliable. When contaminating gastrointestinal (GI) epithelial cells are prevalent among neoplastic cells, these can be highlighted by carcinoembryonic antigen (CEA) staining. CD10 is a cell-surface metallopeptidase normally expressed by the GI epithelial apical border, whose expression is decreased or lost in PDA. We included CD10 in a panel, together with CEA, to discriminate the GI contaminant cells from PDA cells on cell blocks. METHODS: Eight cases of EUS-FNA of PDA, featuring both contaminating GI cells and neoplastic cells, whose corresponding cell blocks were available for immunostaining, were selected. CD10 and CEA were stained on cell blocks by standard methods. RESULTS: CD10 strongly labelled only the GI cells, with a well-defined apical membrane signal; conversely, GI cells did not show CEA staining; benign duodenal cells were faintly labelled in only one case. Malignant cells were positive for CEA and negative for CD10, with the exception of one case with labelled neoplastic cells with weak diffuse cytoplasmic positivity. CD10 apical membrane staining was a feature only seen in benign GI cells. CONCLUSIONS: As a loss of CD10 is a consistent feature of PDA, this marker can be useful, together with CEA, to aid the cytopathologist to identify neoplastic cells in a background rich in GI contaminant cells.

BACKGROUND: To date, few studies of preoperative chemotherapy or chemoradiotherapy (crt) in gastroesophageal junction (gej) cancer have been statistically powered; indeed, gej tumours have thus far been grouped with esophageal or gastric cancer in phase iii trials, thereby generating conflicting results. METHODS: We studied 41 patients affected by locally advanced Siewert type i and ii gej adenocarcinoma who were treated with a neoadjuvant crt regimen [folfox4 (leucovorin-5-fluorouracil-oxaliplatin) for 4 cycles, and concurrent computed tomography-based three-dimensional conformal radiotherapy delivered using 5 daily fractions of 1.8 Gy per week for a total dose of 45 Gy], followed by surgery. Completeness of tumour resection (performed approximately 6 weeks after completion of crt), clinical and pathologic response rates, and safety and outcome of the treatment were the main endpoints of the study. RESULTS: All 41 patients completed preoperative treatment. Combined therapy was well tolerated, with no treatment-related deaths. Dose reduction was necessary in 8 patients (19.5%). After crt, 78% of the patients showed a partial clinical response, 17% were stable, and 5% experienced disease progression. Pathology examination of surgical specimens demonstrated a 10% complete response rate. The median and mean survival times were 26 and 36 months respectively (95% confidence interval: 14 to 37 months and 30 to 41 months respectively). On multivariate analysis, TNM staging and clinical response were demonstrated to be the only independent variables related to long-term survival. CONCLUSIONS: In our experience, preoperative chemoradiotherapy with folfox4 is feasible in locally advanced gej adenocarcinoma, but shows mild efficacy, as suggested by the low rate of pathologic complete response.
RESUMO
BACKGROUND: Somatostatin analogues (SSA) represent one of the main therapeutic option in patients affected with functioning well-differentiated neuroendocrine tumours (NETs). There are no studies specifically focusing on NETs associated with Multiple Endocrine Neoplasia type 1 (MEN1). AIM: To evaluate the efficacy of the long-acting SSA octreotide in MEN1 patients with early-stage duodeno-pancreatic NETs. PATIENTS AND METHODS: Forty patients with MEN1 were retrospectively evaluated. Twenty patients with evidence of one or more MEN1-related duodeno-pancreatic NETs < 20 mm in size (age range 26-61 years) were treated with octreotide long-acting octreotide (LAR) as first-line therapy. Treatment duration ranged 12-75 months. At the baseline radiological evaluation, multiple duodeno-pancreatic NETs (range 1-8, size 3-18 mm) were detected. RESULTS: An objective tumour response was observed in 10%, stable disease in 80% and progression of disease in 10% of cases. In six patients with abnormally increased CgA, gastrin and/or insulin serum concentrations, a significant clinical and hormonal response occurred in 100% of cases and was stable along the time. CONCLUSIONS: Therapy with SSA is highly safe and effective in patients with early-stage MEN1 duodeno-pancreatic NETs, resulting in long-time suppression of tumour and hormonal activity and 10% objective response. This suggests to early start therapy with SSA in patients with MEN1-related NETs.

AIM: The aim of this paper was to compare two anti-incontinence procedures during laparoscopic sacrocolpopexy (LSC) to prevent postoperative stress urinary incontinence (SUI). METHODS: Retrospective analysis of 90 continent hysterectomized patients with vaginal vault prolapse treated with LSC plus colposuspension (group A, N.=30), LSC plus retropubic mid-urethral sling (group B, N.=30), or LSC alone (group C, N.=30). RESULTS: De novo SUI rate resulted significantly (P<0.05) lower in group B than C. No difference was detected regarding de novo urge urinary incontinence. Total reoperation rate resulted significantly (P<0.05) higher in group A than B and lower in group B than C. CONCLUSION: When associated to LSC for preventing SUI, colposuspension and retropubic mid-urethral sling are effective and safe, even if mid-urethral sling seems to provide the best risk/benefit profile.

PURPOSE: The authors compared multidetector-row computed tomography (MDCT) and endoscopic ultrasound (EUS) in the identification of pancreaticoduodenal endocrine tumours (PETs) in patients with multiple endocrine neoplasia type 1 (MEN 1). MATERIALS AND METHODS: Fourteen consecutive patients (eight men and six women, aged 26-54 years) with MEN 1 underwent MDCT performed with a 4- (n=5) or 64- (n=9) detector-row system and EUS done with a radial transducer (7.5-20 MHz) within 7-28 days of each other. Prior to MDCT examination, patients were given 750 cc of water and asked to lie down in the right lateral decubitus for 15 min. Multiphase MDCT images were acquired both before and after the injection of nonionic iodinated contrast material (2 cc/kg) at an injection rate of 4 ml/s, with technical parameters and scan delay varying in relation to the system used. Images were all reconstructed at 3-mm intervals for the three phases (arterial, pancreatic and portal) and evaluated on a dedicated workstation. RESULTS: MDCT detected a total of 25 PETs (3-18 mm) in nine patients. Of these lesions, nine were situated within the duodenal wall and 16 in either the pancreatic head (n=3), body (n=7), or tail (n=6). Three additional lesions were detected retrospectively after EUS imaging. Most (18/22, 81%) were hypervascular nodules, and four appeared as either hypoattenuating or cystic lesions. EUS detected a total of 32 PETs (2-18 mm) in 11 patients. Most lesions (29/32, 90%) appeared hypoechoic and were situated in the duodenal wall (n=15) or in either the pancreatic head (n=10), body (n=6) or tail (n=1). CONCLUSIONS: Our preliminary data indicate that MDCT is complementary to EUS in the identification of PETs in MEN-1 patients.

BACKGROUND: Preoperative chemoradiotherapy (CRT) improves the survival of patients with oesophageal cancer when compared with surgery alone. METHODS: We conducted a phase II, multicenter trial of FOLFOX-4 and cetuximab in patients with locally advanced oesophageal cancer (LAEC) followed by daily radiotherapy (180 cGy fractions to 5040 cGy) with concurrent weekly cetuximab. Cytokines levels potentially related to cetuximab efficacy were assessed using multiplex-bead assays and enzyme-linked immunosorbent assay at baseline, at week 8 and at week 17. Primary end point was complete pathological response rate (pCR). RESULTS: In all, 41 patients were enroled. Among 30 patients who underwent surgery, a pCR was observed in 8 patients corresponding to a rate of 27%. The most frequent grade 3/4 toxicity was skin (30%) and neutropenia (30%). The 36-month survival rates were 85 and 52% in patients with pathological CR or PR vs 38 and 33% in patients with SD or PD. CONCLUSIONS: Incorporating cetuximab into a preoperative regimen for LAEC is feasible; no correlation between cytokines changes and patient outcome was observed. Positron emission tomography/computed tomography study even if influenced by the small number of patients appears to be able to predict patients outcome both as early and late metabolic response.

BACKGROUND: Presacral tumors are more frequently benign, and only occasionally malignant, showing a slow growth and an incidence of 1:40.000. They are asymptomatic in the 26-50% of the cases. When symptoms occur, these are related to the dimensions of the tumor, to its location and to the presence of infection. CASE REPORT: We report the case of a 69-year old woman with a lower abdominal pain associated with paresthesia and ipostenia of the right inferior limb. Digital rectal examination showed a fixed, mild tender and hard tumor of the posterior rectal wall. CT, MR and CT-guided biopsy sequently performed revealed a solid, dishomogeneous mass, located in the presacral region, with a connective likely origin, without pelvic lymphoadenopathy. The operation allowed to esteem a mass which was tenaciously adherent to the sacrum. We performed a total excision. Final histological diagnosis was myelolipoma. CONCLUSIONS: The Authors' opinion is that the en-bloc resection of these tumors with an anterior surgical approach allows a histological diagnosis of the nature, representing the best treatment for potentially malignant lesions, which are frequently radio and chemo-resistant.

Versione italiana Riassunto: Il ruolo dell'endoscopia nei tumori neuroendocrini gastroenteropancreatici. L. Magno, L. Sivero, V. Napolitano, S. Ruggiero, G. Fontanarosa, S. Massa I tumori neuroendocrini (NET) gastro-entero-pancreatici (GEP) sono neoplasie rare che originano dalle cellule neuroendocrine del tubo digerente e del pancreas. L'endoscopia digestiva e l'ecoendoscopia rivestono un ruolo importante nella diagnosi, stadiazione e sorveglianza dei pazienti con NET. Inoltre, in casi selezionati, le tecniche endoscopiche operative consentono il trattamento di queste neoplasie in fase precoce. English version Summary: The role of endoscopy in gastroenteropancreatic neuroendocrine tumors. L. Magno, L. Sivero, V. Napolitano, S. Ruggiero, G. Fontanarosa, S. Massa Gastroenteropancreatic (GEP) neuroendocrine tumors (NET) are rare neoplasia arisen from neuroendocrine cells present in the gut mucosa and pancreas. Digestive endoscopy and endoscopic ultrasonography play a relevant role in NET diagnosis, stadiation and surveillance. Moreover, in selected patients, surgical endoscopy allows the tratment of these cancers at an early stage.

A 57-year-old male patient was admitted in our Department for a non-variceal upper gastrointestinal massive bleeding. In accordance with the clinical guidelines, the patient underwent an early endoscopy (within 24 hours from admission), which showed the source of bleeding in the second portion of the duodenum. An endoscopic haemostatic injection with dilute adrenalin (epinephrine, 1:10.000) was then performed. After 8 hours, severe recidive bleeding occurred with reduced haemoglobin levels, which led us to an emergency surgical treatment. A gastric resection was performed, followed by the application of high-viscous gel (Floseal) into the source of bleeding within the duodenal lumen. This technique allowed to obtain a definitive haemostasis without long-term complications. Our experience suggests that the intra-operative application of Floseal can be an effective alternative to traditional haemostatic techniques in the emergency surgical treatment of upper gastrointestinal bleeding. This also provides additional time to perform other haemostatic techniques techniques avoiding the precarious haemodynamic conditions of a patient in emergency.

Analyzing a complex case and referring to the literature, the authors describe abdominal compartmental syndrome as a complication of Fournier's gangrene, stressing out the importance of an early diagnosis to perform prompt and effective treatment. The characteristic of this case is not represented only by the Fournier's gangrene rarity, but also by the appearance of an abdominal compartmental syndrome due to the gangrene extension from the scrotum to the abdominal wall and cavity through the spermatic funiculus. The treatment of the abdominal compartmental syndrome was the surgical toilette of the necrotic regions (scrotum, abdominal wall and cavity) together with an orchiectomy.
