ABSTRACT

Introducción: El olfato tiene una gran importancia en la calidad de vida. Los accesos quirúrgicos selares pueden realizarse por vía transcraneal, transeptal y transnasal, y pueden generar hiposmia al incluir resecciones que afectan a la mucosa olfatoria. Objetivo: Determinar la existencia de alteración persistente en el olfato ocasionado por los accesos quirúrgicos transeptal y transnasal en pacientes operados por adenoma hipofisiario en el Instituto de Neurocirugía Dr. Asenjo. Material y Método: Estudio prospectivo de cohorte con comparación de resultados olfatorios ("sniffin' sticks" versión extendida) y encuesta SNOT-22 pre y poscirugía por adenoma hipofisiario por vía transeptal o transnasal. Se utilizaron medidas estadísticas de comparación de pruebas pareadas paramétricas y no paramétricas según las características de las variables evaluadas. Resultados: Se reclutaron 60 pacientes, completando el seguimiento 39. En 21 se realizó acceso transeptal y en 18 transnasal. Al analizar el total de pacientes y por cada técnica quirúrgica, no hubo diferencias significativas en los puntajes del "sniffin' sticks" versión extendida y tampoco en SNOT-22. Conclusión: La literatura describe incidencia de hiposmia posoperatoria muy variable, entre 0% y 88%, con mediciones subjetivas y objetivas. Existe una predilección por la técnica endoscópica a nivel internacional, por lo que cuenta con estudios de mejor calidad. A nivel nacional existen dos estudios previos que han encontrado tasas de hiposmia posoperatoria de 10% y 14%. En este estudio no hubo diferencias significativas en los puntajes obtenidos en la prueba de olfato entre el pre y posoperatorio.


Introduction: Olfaction is of great importance in quality of life. Surgical accesses to the sellar region can be performed by transcranial, transseptal, and transnasal routes, which can generate hyposmia when including resections that affect the olfactory mucosa. Aim: To determine the existence of persistent alteration in olfaction caused by transseptal and transnasal surgical accesses in patients operated for pituitary adenoma at the Instituto de Neurocirugía Dr. Asenjo. Material and Method: Prospective cohort study with comparison of olfactory results ("sniffin' sticks" extended version) and SNOT-22 survey pre and post transseptal or transnasal surgery for pituitary adenoma. Parametric and non-parametric paired test comparison statistics were used according to the characteristics of the variables evaluated. Results: 60 patients were recruited and 39 completed follow-up. 21 patients underwent transseptal access and 18 underwent transnasal access. When analyzing the total number of patients and for each surgical technique, there were no significant differences in the scores obtained in the "sniffin' sticks" extended version and neither for the SNOT-22. Conclusion: The literature describes a highly variable incidence of postoperative hyposmia, between 0% and 88%, with subjective and objective measurements. There is a predilection for the endoscopic technique at an international level, which is why it has better quality studies. At the national level there are two previous studies that have found postoperative hyposmia rates of 10% and 14%. In this study there were no significant differences in the scores obtained between pre and postoperative olfaction test.

ABSTRACT

Abstract Aim: To locate and characterize colorectal adenomas endoscopically and histologically in a cohort of patients undergoing colonoscopy in Medellín, Colombia. Materials and methods: Descriptive cross-sectional study. We included patients older than 18 years who underwent colonoscopy between February and July 2020 at a specialized center in Medellín, Colombia. We determined the incidence of adenomas, their location in different segments of the colon, their endoscopic and histological characteristics, and cases of colorectal cancer (CRC) and high-grade dysplasia (HGD). Results: 992 colonoscopies were performed, finding colorectal polyps in 266 patients, of which 208 had adenomas. We resected 461 polyps, of which 336 were adenomas (72 %). The histological type with the highest representation was tubular (78 %). The location of adenomas was 37 % in the right colon, 25 % in the transverse colon, and 38 % in the left colon. CRC cases were nine per 1,000 patients, including advanced carcinoma and carcinoma in situ (HGD). Conclusions: Given the incidence of adenomas in the right and transverse colon, rectosigmoidoscopy is discouraged as a screening study for CRC. Tubular adenomas, sessile in appearance and tiny, predominated in the population studied. We recommend screening in the population over 40 years of age and the search for precursor lesions as strategies to reduce morbidity and mortality rates due to CRC.


Resumen Objetivo: localización y caracterización endoscópica e histológica de los adenomas colorrectales en una cohorte de pacientes sometidos a colonoscopia en Medellín, Colombia. Materiales y métodos: estudio descriptivo de corte transversal. Se incluyeron pacientes mayores de 18 años sometidos a colonoscopia entre febrero y julio de 2020 en un centro especializado de Medellín, Colombia. Se determinó la incidencia de adenomas, su localización en los diferentes segmentos del colon, sus características endoscópicas e histológicas, así como también los casos de cáncer colorrectal (CCR) y displasia de alto grado. Resultados: se realizaron 992 colonoscopias y se encontraron pólipos colorrectales en 266 pacientes, de los cuales 208 tenían adenomas. En total se resecaron 461 pólipos, de los cuales 336 fueron adenomas (72 %). El tipo histológico con mayor representación fue el tubular (78 %). La localización de adenomas fue del 37 % en el colon derecho, 25 % en el transverso y 38 % en el colon izquierdo. La cantidad de casos de CCR fue de 9 por 1000 pacientes, que incluyen carcinoma avanzado y carcinoma in situ (DAG). Conclusiones: dada la incidencia de adenomas en el colon derecho y transverso, no se recomienda la rectosigmoidoscopia como estudio de tamizaje para CCR. En la población estudiada fueron predominantes los adenomas tubulares, de aspecto sésil y tamaño diminuto. Se recomienda el tamizaje en la población mayor de 40 años y la búsqueda de lesiones precursoras como estrategias para disminuir las tasas de morbimortalidad por CCR.

ABSTRACT

Introducción. Los adenomas gigantes de hipófisis (AGHs) son aquellos tumores con un diámetro máximo ≥4 cm en cualquier dirección, representando del 5% al 14% del total de los adenomas que se tratan quirúrgicamente. Su manejo terapéutico es desafiante ya que, debido a su extensión hacia otras estructuras cerebrales,está asociado a un riesgo mayor de complicaciones quirúrgicas, con una menor tasa de resección total. El objetivo de este trabajo fue evaluar el impacto de la cirugía endoscópica transesfenoidal en AGHs, analizando las variables asociadas a resultados visuales, endocrinológicos y según el grado de resección. Pacientes y Métodos. Se evaluó en 44 pacientes con AGHs(diámetro ≥4 cm y/o volumen ≥10 ml) la presentación visual, endocrinológica e imágenes. Se analizaron estadísticamente resultados visuales, endocrinológicos, grado de resección y complicaciones quirúrgicas. Resultados. Edad promedio de 48.8 años, 24 mujeres y 20 hombres. Presentación: déficit del campo visual (93.1%), hipopituitarismo (61.3%), cefalea (54.5%). Diámetro, volumen y extensión supraselar promedios: 4.8 cm, 20.3 ml, 1.8 cm, respectivamente. Campo visual: mejoría: 83.3%, sin cambios: 9.5%, mayormente en síntomas bilaterales (p<0.0001). Desmejoríavisual: 0%. En resección total: mayor posibilidad de mejoría visual (p=0.040). Buenos resultados endocrinológicos: 85.7%. Tasa de resección total: 52.3%. Resección subtotal: más frecuente con invasión del seno cavernoso (p=0.014). Sin diferencias en el grado de resección según diámetro, volumen, extensión supraselar, forma ni aspecto. Hipopituitarismo: 4.2%. Diabetes insípida: 9.5%, asociada a mayor diámetro (p=0.038) o extensión supraselar (p=0.010) y aspecto sólido (p=0.023). Fístula de LCR: 7.1%. Conclusión. La resección total puede lograrse en la mitad de los casos, siendo la limitante principal el grado de invasión del seno cavernoso y no el aspecto morfológico del AGH per se. Aun así, los resultados visuales y endocrinológicos son muy buenos. En resecciones incompletas se logra el control de la enfermedad mediante tratamientos complementarios


Introduction. Giant pituitary adenomas (sGAs) are those tumors with a maximum diame- ter ≥4 cm in any direction, representing 5% to 14% of all adenomas that are treated surgi- cally. Its therapeutic management is challenging since, due to its extension to other brain structures, it is associated with a higher risk of surgical complications, with a lower rate of total resection. Te objective of this work was to evaluate the impact of transsphenoidal endoscopic surgery on AGHs, analyzing the variables associated with visual and endocri- nological results and according to the degree of resection. Patients and Methods. Visual, endocrinological and imaging presentation were evaluated in 44 patients with sHAA (dia- meter ≥4 cm and/or volume ≥10 ml). Visual and endocrinological results, degree of resection and surgical complications were statistically analyzed. Results. Average age of 48.8 years, 24 women and 20 men. Presentation: visual field deficit (93.1%), hypopituitarism (61.3%), headache (54.5%). Average diameter, volume and suprasellar extension: 4.8 cm, 20.3 ml, 1.8 cm, respectively. Visual field: improvement: 83.3%, no changes: 9.5%, mostly in bilate- ral symptoms (p<0.0001). Visual impairment: 0%. In total resection: greater possibility of visual improvement (p=0.040). Good endocrinological results: 85.7%. Total resection rate: 52.3%. Subtotal resection: more frequent with invasion of the cavernous sinus (p=0.014). No differences in the degree of resection according to diameter, volume, suprasellar exten- sion, shape or appearance. Hypopituitarism: 4.2%. Diabetes insipidus: 9.5%, associated with greater diameter (p=0.038) or suprasellar extension (p=0.010) and solid appearance (p=0.023). CSF fistula: 7.1%. Conclusion. Total resection can be achieved in half of the cases, the main limitation being the degree of invasion of the cavernous sinus and not the morphological appearance of the HGA per se. Even so, the visual and endocrinological results are very good. In incomplete resections, disease control is achieved through com- plementary treatments

ABSTRACT

Introducción: El adenoma tubular de mama una patología benigna que se presenta en mujeres jóvenes como una masa unilateral que genera asimetría mamaria y se tiende a confundir con fibroadenoma gigante juvenil, diferenciándose en el estudio histopatológico. Es una patología muy rara, con excepcionales casos reportados en la literatura de mayor a 10 cm, motivo de presentación de este caso. Caso clínico: Presentamos el caso de una mujer de 21 años de edad con una masa de10 cm aproximadamente en la mama derecha, de 1 año de evolución con crecimiento paulatino, sin síntomas asociados. El examen físico sin hipertrofia de ganglios axilares. Taller diagnóstico: La paciente fue sometida a una exéresis quirúrgica reportando en el estudio patológico definitivo un adenoma tubular de mama. Conclusión: Como conclusión se trata de una patología poco frecuente, pero debemos conocerla y tener un mínimo de sospecha diagnóstica para evitar confusiones con patología mamaria maligna.


Introduction: Tubular adenoma of the breast is a benign pathology in young women as a unilateral mass that generates breast asymmetry and tends to be confused with giant juvenile fibroadenoma, differing in the histopathological study. It is a very rare pathology, with exceptional cases reported in the literature of greater than 10 cm, which is the reason for presenting this case. Clinical case: We present the case of a 21-year-old woman with a mass of approximately 10 cm in the right breast, of 1 year of evolution with gradual growth, without associated symptoms. Physical examination showed no axillary node hypertrophy. Diagnostic workshop: The patient underwent surgical excision, reporting a tubular adenoma of the breast in the definitive pathological study. Conclusion: It is a rare pathology, but we must know it and have a minimum of diagnostic suspicion to avoid confusion with malignant breast pathology.

ABSTRACT

Objective: To determine the impact of the quality of colonoscopy examination for colorectal cancer screening. Methods: Retrospective observational study ofmedical records from patients treated at the endoscopy and colonoscopy service of Hospital Universitário Evangélico Mackenzie (Curitiba, PR, Brazil) from January 2019 to January 2020. Results: The analysis was based on 337 medical records from patients with adenomas identified during colonoscopy, and 1,385 medical records from patients without adenomas. The estimated occurrence rate of diagnosis of adenoma during colonoscopy in the target population of the study was of 19.6%, with a 95% confidence interval ranging from 17.7 to 21.5%. Of the 337 patients with adenoma, 136 (40.4%) presented the advanced form. Statistical analysis indicated a significant association between the quality of colonoscopy preparation and test completion. Conclusion: The quality of colonoscopy images is a critical factor for colorectal cancer screening, as it leads to higher rates of adenoma detection and test completion. (AU)

ABSTRACT

Abstract Aim: To determine the adenoma detection rate (ADR) and identify the indications for a colonoscopy that predict adenomas. Materials and methods: Cross-sectional study. We included patients older than 18 years who underwent colonoscopy between February and July 2020 at a specialized center in Medellín, Colombia. We estimated the ADR and identified the indications for a colonoscopy, considered predictors for finding adenomas. Results: The overall adenoma detection was 21 % (n = 992) and ADR in the screening population was 25 %. The range of 40-49 years contributed 12 % of the total number of adenomas detected, and the male population had a higher incidence (OR 1.73; 95 % CI 1.25-2.38; p < 0.001). Personal history of polyps (OR 1.86; 95 % CI 1.25-2.78; p = 0.002) and fecal occult blood (OR 2.67; 95 % CI 1.12-6.35; p 0.026) are deemed predictors for finding adenomas. LCI filters showed better results in detecting lesions (OR 1.43; 95 % CI 1.02-2.0). Conclusions: The indications for a colonoscopy can predict the probability of detecting adenomas. Male gender, a personal history of polyps, fecal occult blood, and the search for adenomas after the age of 40 are the variables that increase the probability of finding adenomas. The use of LCI filters increases lesion detection. The suggested age to start CRC screening is 40 years.


Resumen Objetivo: determinar la tasa de detección de los adenomas (TDA) e identificar las indicaciones de colonoscopia que predicen su hallazgo. Materiales y métodos: estudio de corte transversal. Se incluyeron pacientes mayores de 18 años sometidos a colonoscopia entre febrero y julio de 2020 en un centro especializado de Medellín, Colombia. Se estimó la TDA y se identificaron las indicaciones de colonoscopia, que se consideran predictores para el hallazgo de adenomas. Resultados: la detección general de adenomas fue del 21 % (n = 992) y la TDA en la población de tamizaje fue del 25 %. El rango de 40 a 49 años aportó el 12 % del total de adenomas detectados y la población masculina tuvo mayor incidencia (OR 1,73; IC 95 % 1,25-2,38; p < 0,001). El antecedente personal de pólipos (OR 1,86; IC 95 % 1,25-2,78; p = 0,002) y la presencia de sangre oculta en heces (OR 2,67; IC 95 % 1,12-6,35; p 0,026) se consideran predictores para el hallazgo de adenomas. El uso de filtros LCI mostró mejores resultados en la detección de las lesiones (OR 1,43; IC 95 % 1,02-2,0). Conclusiones: las indicaciones de la colonoscopia pueden predecir la probabilidad de detección de adenomas. El género masculino, el antecedente personal de pólipos, la presencia de sangre oculta en heces y la búsqueda de adenomas a partir de los 40 años son las variables que aumentan la probabilidad de encontrar adenomas. El uso de filtros LCI aumenta la detección de lesiones. La edad sugerida para el inicio del tamizaje de CCR es a partir de los 40 años.

ABSTRACT

El hiperparatiroidismo primario es el tercer trastorno endocrino más común, alrededor del 85% de los casos se debe a adenomas paratiroideos. El tratamiento definitivo es la paratiroidectomía, siendo la causa más común de fracaso la resección inadecuada y la localización de tejido ectópico, representando un desafío para el cirujano. En el presente trabajo se presenta el caso de un paciente con diagnóstico de adenoma paratiroideo mediastínico gigante, siendo este el de mayor longitud descrito en la literatura en los últimos 10 años. Caso clínico: Paciente masculino de 70 años de edad quien consulta por presentar convulsiones, polidipsia y poliuria. Se determinan niveles elevados de PTH, hipercalcemia e hipofosfatemia. Estudios de imagen describen lesión alargada localizada en espacio paratraqueal derecho extendiéndose hasta el polo inferior de lóbulo tiroideo derecho. Se decide resolución quirúrgica, mediante la realización de cervicotomía y toracoscopia con evolución satisfactoria del paciente. Conclusión: Los adenomas paratiroideos ectópicos constituyen una causa común de falla quirúrgica e hiperparatiroidismo persistente, su sospecha es de gran importancia. El tratamiento definitivo es la cirugía. La localización preoperatoria por pruebas de imagen es fundamental para seleccionar correctamente la técnica quirúrgica y garantizar el éxito de la cirugía. El abordaje cervical y toracoscópico es una alternativa segura y eficaz(AU)


Primary hyperparathyroidism is the third most common endocrine disorder, about 85% of cases are due to parathyroid adenomas. The definitive treatment is parathyroidectomy, being the most frequent cause of failure the inadequate resection and the location of ectopic tissue. The ectopic parathyroid adenomas represent a challenge for the surgeon. In this paper a case of a patient diagnosed with giant mediastinal parathyroid adenoma is presented, and is the largest reported in the literature in the last 10 years. Clinical case: 70-year-old male patient presented with seizures, polydipsia and polyuria, reason for which he consults. Elevated PTH levels, hypercalcemia, and hypophosphatemia are determined. Imaging studies report an elongated lesion located in the right paratracheal space that extends to the lower pole of the right thyroid lobe. Surgical resolution was decided, by performing cervicotomy and thoracoscopy with satisfactory recovery of the patient. Conclusion: Ectopic parathyroid adenomas are a common cause of surgical failure and persistent hyperparathyroidism; their suspicion is of great importance. The definitive treatment is surgery. Preoperative localization through imaging tests is essential to correctly select the surgical technique and guarantee the success of the surgery, the cervical and thoracoscopic approach is a safe and effective alternative(AU)

ABSTRACT

Objective: To investigate the related factors and treatments of delayed cerebrospinal fluid rhinorrhea (CFR) after invasive pituitary adenoma (IPA) surgery. Methods: One hundred and forty-two patients with IPA treated in Tianjin Huanhu Hospital from January 2014 to January 2019 were analyzed retrospectively, including 62 males and 80 females, aging from 38 to 67 years. The clinical data of patients before and after operation were collected. All patients with postoperative CFR underwent endoscopic CFR repair. During the operation, residual or recurrent pituitary adenomas were resected, the dura around the leak was enlarged and the necrotic tissue was removed. For those who still had fluid leakage after repair, the necrotic tissue was cleaned up, the leakage was filled and reinforced under endoscopy. Endoscopic rhinorrhea repair was performed if necessary. The cerebrospinal fluid leak was repaired with multi-layer materials. The related risk factors of delayed CFR after operation were analyzed. SPSS 19.0 software was used for statistical analysis. Results: Among the 142 patients in this group, 64 cases underwent total tumor resection and 78 cases underwent non-total tumor resection. They were followed up for 6 to 72 months. Thirty-one cases had delayed CFR, with an incidence of 21.83%, and occurred between 1 and 5 years postoperatively, with an average of 2.4 years. All 31 patients with delayed CFR underwent endoscopic CFR repair. The nasal endoscopy was rechecked at 2 weeks, 1 month, 3 months and 6 months after operation. Twenty-eight patients were repaired successfully after 1 operation, while 2 patients after 2 operations and 1 patient after 3 operations. These patients were followed up for 6 to 60 months, and no CFR occurred again. Univariate analysis showed that the degree of tumor resection, recurrence, size, texture, postoperative radiotherapy and operator experience were the risk factors of delayed CFR (all P<0.05). Multivariate analysis showed that the degree of tumor resection and recurrence were the highest independent risk factors for postoperative CFR, and tumor size, texture, postoperative radiotherapy and operator experience were the independent risk factors in this study. Conclusions: Delayed CFR after IPA is related to the degree of tumor resection, recurrence, size, texture, postoperative radiotherapy and the operator experience. It is necessary to completely remove the tumor under endoscope, to expand resection of the dura and necrotic tissue around the leak, to repair the defect with multi-layer materials, to follow-up closely and to repair timely after operation.

ABSTRACT

Objective: To investigate the effects of high risk factors questionnaire (HRFQ), Asia-Pacific colorectal screening (APCS) score and their combinations with fecal immunochemical test (FIT) in screening advanced colorectal neoplasia, in order to provide an evidence for further optimization of cancer screening program. Methods: A retrospective cohort study method was used to summarize and analyze the results of colorectal tumor screening in Jiashan County, Zhejiang Province from March 2017 to July 2018. Those with severe diseases that were not suitable for colonoscopy and those with mental and behavioral abnormalities who can not cooperate with the screening were excluded. Those who met any one or more of the followings in the HRFQ questionnaire were classified as high-risk people of HRFQ: (1) first-degree relatives with a history of colorectal cancer; (2) subjects with a history of cancer or any other malignant tumor; (3) subjects with a history of intestinal polyps; (4) those with two or more of the followings: chronic constipation (constipation lasted for more than 2 months per year in the past two years), chronic diarrhea (diarrhea lasted for more than 3 months in the past two years, and the duration of each episode was more than one week), mucus and bloody stools, history of adverse life events (occurring within the past 20 years and causing greater trauma or distress to the subject after the event), history of chronic appendicitis or appendectomy, history of chronic biliary disease or cholecystectomy. In this study, those who were assessed as high risk by HRFQ were recorded as "HRFQ (+)", and those who were not at high risk were recorded as "HRFQ (-)". The APCS questionnaire provided risk scores based on 4 risk factors including age, gender, family history and smoking: (1) age: 2 points for 50-69 years old, 3 points for 70 years old and above; (2) gender: 1 point for male, 0 point for women; (3) family history: 2 points for first-degree relatives suffering from colorectal cancer; (4) smoking: 1 point for current or past smoking, 0 point for non-smokers. The population was divided into low-risk (0-1 point), intermediate-risk (2-3 points), and high-risk (4-7 points). Those who were assessed as high risk by APCS were recorded as "APCS (+)", and those with intermediate and low risk were recorded as "APCS (-)". The hemoglobin threshold for a positive FIT was set to 100 μg/L. Those who were assessed as high risk by APCS with positive FIT were recorded as "APCS+FIT (+)". Those who were assessed as high risk by APCS with negative FIT, those who were assessed by APCS as low-middle risk with positive FIT, and those who were assessed by APCS as low-middle with negative FIT were all recorded as "APCS+FIT(-)". Observation indicators in this study were as follows: (1) the screening compliance rate of the cohort and the detection of advanced colorectal tumors; (2) positive predictive value, negative predictive value, sensitivity and specificity of HRFQ and APCS and their combination with FIT for screening advanced colorectal tumors; (3) comparison of the detection rate between HRFQ and APCS questionnaire for different colorectal lesions. Using SPSS 21.0 software, the receiver operating characteristic (ROC) curve was drawn to evaluate the clinical value of HRFQ and APCS combined with FIT in screening advanced colorectal tumors. Results: From 2017 to 2018 in Jiashan County, a total of 53 268 target subjects were screened, and 42 093 people actually completed the questionnaire, with a compliance rate of 79.02%. A total of 8145 cases underwent colonoscopy. A total of 3607 cases among HRFQ positive population (5320 cases) underwent colonoscopy, and the colonoscopy compliance rate was 67. 80%; 8 cases were diagnosed with colorectal cancer and 88 cases were advanced colorectal adenoma. A total of 2977 cases among APCS positive population (11 942 cases) underwent colonoscopy, and the colonoscopy compliance rate was 24.93%; 17 cases were diagnosed with colorectal cancer and 148 cases were advanced colorectal adenoma. The positive rate of HRFQ screening was lower than that of APCS [12.6% (5320/42 093) vs. 28.4% (11 942/42 093), χ2=3195. 547, P<0.001]. In the FIT positive population (6223 cases), a total of 4894 cases underwent colonoscopy, and the colonoscopy compliance rate was 78.64%; 34 cases were diagnosed with colorectal cancer and 224 cases were advanced adenoma. The positive predictive values of HRFQ and APCS and their combination with FIT for screening advanced colorectal tumors were 2.67%, 5.54%, 5.44%, and 8.56%; negative predictive values were 94.89%, 96.85%, 96.11% and 96.99%; sensitivity was 29.27%, 50.30%, 12.20 % and 39.02%; specificity was 55.09%, 64.03%, 91.11% and 82.51%, respectively. The ROC curves constructed by HRFQ, APCS, FIT, HRFQ+FIT and APCS+FIT indicated that APCS+FIT presented the highest efficacy in screening advanced colorectal tumors (AUC: 0.608, 95%CI: 0.574-0.642). The comparison of the detection rates of different colorectal lesions between HRFQ and APCS questionnaires showed that there were no significant differences in detection rate of inflammatory polyps and hyperplastic polyps between the two questionnaires (both P>0.05). However, as compared to HRFQ questionnaire, APCS questionnaire had higher detection rates in non-advanced adenomas [26.10% (777/2977) vs. 19.43% (701/3607), χ2=51.228, P<0.001], advanced adenoma [4.97% (148/2977) vs. 2.44% (88/3607), χ2=30.249, P<0.001] and colorectal cancer [0.57% (17 /2977) vs. 0.22% (8/3607), χ2=5.259, P=0.022]. Conclusions: APCS has a higher detection rate of advanced colorectal tumors than HRFQ. APCS combined with FIT can further improve the effectiveness of advanced colorectal tumor screening.

ABSTRACT

Colonoscopy with endoscopic resection of detected colonic adenomas interrupts the adenoma-carcinoma sequence and reduces the incidence of colorectal cancer and cancer-related mortality. In the past decade, there have been significant developments in instruments and techniques for endoscopic polypectomy. Guidelines have been formulated by various professional bodies in Europe, Japan and the United States, but some of the recommendations differ between the various bodies. An expert professional workgroup under the auspices of the Academy of Medicine, Singapore, was set up to provide guidance on the endoscopic management of colonic polyps in Singapore. A total of 23 recommendations addressed the following issues: accurate description and diagnostic evaluation of detected polyps; techniques to reduce the risk of post-polypectomy bleeding and delayed perforation; the role of specific endoscopic resection techniques; the histopathological criteria for defining endoscopic cure; and the role of surveillance colonoscopy following curative resection.

ABSTRACT

Introducción: el sangrado gastrointestinal de origen oscuro es una entidad poco frecuente y se reserva a los casos en los que ya se ha realizado exploración del intestino delgado (endoscópica/radiológica) sin encontrar la causa. Actualmente el estándar de oro es la videocápsula, que se ha descrito como una técnica segura, útil y eficaz para el diagnóstico y tratamiento de las enfermedades del intestino delgado. Objetivo: describir variables demográficas, indicaciones, hallazgos, segmento explorado, tratamiento y tiempo de procedimiento quirúrgico de la enteroscopía transoperatoria en 15 pacientes con diagnóstico de sangrado de tubo digestivo de origen oscuro. Material y métodos: se incluyeron 15 pacientes adultos con el diagnóstico de sangrado de origen oscuro con panendoscopía y colonoscopía negativa a sangrado. A todos se les realizó laparotomía exploradora y enteroscopía transoperatoria con un gastroduodenoscopio. Resultados: se realizaron 15 enteroscopías transoperatorias con gastroduodenoscopio; 10 en mujeres y 5 en hombres, con promedio de edad de 67.2 años. Se exploró la tercera y cuarta porción del duodeno, yeyuno e íleon terminal. Los diagnósticos encontrados fueron enfermedad de Crohn en 1 paciente (6.66%), adenomas en 2 (13.3%), divertículo yeyunal en 6 (40%) y angiectasias en 6 casos (40%). La localización fue en yeyuno [12 casos (80%)] e íleon [3 casos (20%)]. Conclusiones: la enteroscopía intraoperatoria es una alternativa diagnóstica en el sangrado de origen oscuro cuando no se cuente con la enteroscopía doble balón o la videocápsula endoscópica.


Background: Bleeding of dark origin is a rare entity and it is reserved for cases in which exploration of the small intestine has already been performed (endoscopic / radiological) without finding the cause. Currently, the gold standard is the videocapsule which has been described as a safe, useful and effective technique for the diagnosis and treatment of diseases of the small intestine. Objective: The objective was to describe demographic variables, indications, findings, explored segment, treatment and time of the surgical procedure of the intraoperative enteroscopy in 15 patients with a diagnosis of gastrointestinal bleeding of dark origin. Material and methods: 15 adult patients with the diagnosis of bleeding of dark origin with panendoscopy and negative colonoscopy to bleeding were included. All of these underwent exploratory laparotomy and intraoperative enteroscopy with a gastroduodenoscope. Results: 15 intraoperative enteroscopies were performed with a gastroduodenoscope; 10 women and 5 men with an average age of 67.2 years. Third and fourth portions of the duodenum, jejunum, and terminal ileum were explored. The diagnoses found were Crohn's disease 1 (6.66%), Adenomas 2 (13.3%), jejunal diverticulum 6 (40%) and angiectasias in 6 cases (40%). The location was in jejunum, 12 cases (80%) and ileum, 3 cases (20%). Conclusions: Intraoperative enteroscopy is a diagnostic alternative in bleeding of dark origin when there is no double balloon enteroscopy or endoscopic video capsule.

ABSTRACT

Abstract: Introduction Colorectal carcinoma (CRC) is the most common gastrointestinal neoplasm in the world, accounting for 15% of cancer-related deaths. This condition is related to different molecular pathways, among them the recently described serrated pathway, whose characteristic entities, serrated lesions, have undergone important changes in their names and diagnostic criteria in the past thirty years. The multiplicity of denominations and criteria over the last years may be responsible for the low interobserver concordance (IOC) described in the literature. Objectives: The present study aims to describe the evolution in classification of serrated lesions, based on the last three publications of theWorld Health Organization (WHO) and the reproducibility of these criteria by pathologists, based on the evaluation of the IOC. Methods: A search was conducted in the PubMed, ResearchGate and Portal Capes databases, with the following terms: sessile serrated lesion; serrated lesions; serrated adenoma; interobserver concordance; andreproducibility.Articlespublished since 1990were researched. Results and Discussion: The classification of serrated lesions in the past thirty years showed different denominations and diagnostic criteria. The reproducibility and IOC of these criteria in the literature, based on the kappa coefficient, varied in most studies, from very poor to moderate. Conclusions: Interobserver concordance and the reproducibility of microscopic criteria may represent a limitation for the diagnosis andappropriatemanagementof these lesions. It is necessary to investigate diagnostic tools to improve the performance of the pathologist's evaluation, for better concordance, and, consequently, adequate diagnosis and treatment. (AU)

ABSTRACT

A senile male captive bush dog (Speothos venaticus) presented a small perianal cutaneous nodule. Histologically, there was an ulcerated round cell tumor composed of well differentiated mast cells with abundant intracytoplasmic purple Giemsa-positive granules, with a diffuse eosinophilic infiltrate. Immunohistochemistry revealed that 30% of the neoplastic cells were positive for Kit in the cytoplasm and cell membrane, and all neoplastic cells were negative for MAC and CD3. Less than 10% of the neoplastic cells were positive for Ki67. At necropsy other primary tumors were identified in this animal, including an intestinal adenoma, an adrenal cortex adenoma and a testicular interstitial cell tumor.(AU)


Um cachorro-vinagre (Speothos venaticus) apresentou um nódulo cutâneo pequeno na região perianal. Histologicamente havia neoplasia cutânea de células redondas e ulcerada, constituída por mastócitos bem diferenciados, com abundantes grânulos citoplasmáticos metacromáticos na coloração de Giemsa e infiltrado eosinofílico difuso. A imuno-histoquímica demonstrou que 30% das células neoplásicas eram positivas para a proteína Kit no citoplasma e na membrana celular. As células foram negativas para MAC e CD3. Menos de 10% das células neoplásicas foram positivas para Ki67. Durante a necropsia, foram identificados outros tumores primários, como adenoma intestinal, adenoma cortical da adrenal e tumor de células intersticiais do testículo.(AU)

ABSTRACT

Introducción: El adenoma del paladar blando es frecuente en mujeres, aunado a los cambios fisiológicos que suceden durante el embarazo, es de presumir que la gestante puede presentar una vía aérea difícil. Objetivo: Describir el abordaje de la vía aérea en una gestante con adenoma del paladar blando. Presentación del caso: Se trata de una gestante de 20 años de edad con antecedentes patológicos personales de asma bronquial, alergia a los anestésicos locales, que presenta un adenoma en el paladar blando que impide ver la estructura de la orofaringe, Mallampatti IV, anunciada para procedimiento quirúrgico de urgencia para realizarle cesárea segmentaria anterior. Conclusiones: La embarazada presenta mayor incidencia de vía aérea difícil comparado con la población general, debido a los cambios fisiológicos que presenta en este periodo, si a ello se le adiciona la presencia de un tumor oro faríngeo que imposibilita la manipulación de la vía aérea, la evaluación preoperatoria y trazar una estrategia multidisciplinaria, constituyen los pilares para evitar complicaciones potencialmente fatales(AU)


Introduction: Adenoma of soft palate is frequent in women, together with the physiological changes that occur during pregnancy. The pregnant woman is to be presumed to have a difficult airway. Objective: To describe the airway managment in a pregnant woman with adenoma of soft palate. Case presentation: This is a 20-year-old pregnant woman (Mallampati IV) with a personal pathological history of bronchial asthma and allergy to local anesthetics, who presents an adenoma of soft palate that avoids seeing the oropharynx structure, announced for emergency surgical procedure for an anterior segmental cesarean section. Conclusions: The pregnant woman has a higher incidence of difficult airway compared to the general population, due to the physiological changes that she presents in this period. If, apart from this situation, the presence is considered of an oropharyngeal tumor that makes it impossible to manipulate the airway, preoperative assessment and tracing a multidisciplinary strategy are the pillars to avoid potentially fatal complications(AU)

ABSTRACT

ABSTRACT Objective: To analyze the clinical, laboratory, and radiological findings and management of patients with clinical pituitary apoplexy and to screen for aryl hydrocarbon receptor-interacting protein (AIP) mutations. Subjects and methods: The clinical findings were collected from the medical records of consecutive sporadic pituitary adenoma patients with clinical apoplexy. Possible precipitating factors, laboratory data, magnetic resonance imaging (MRI) findings and treatment were also analyzed. Peripheral blood samples were obtained for DNA extraction from leukocytes, and the entire AIP coding region was sequenced. Results: Thirty-five patients with pituitary adenoma were included, and 23 (67%) had non-functioning pituitary adenomas. Headache was observed in 31 (89%) patients. No clear precipitating factor was identified. Hypopituitarism was observed in 14 (40%) patients. MRI from 20 patients was analyzed, and 10 (50%) maintained a hyperintense signal in MRI performed more than three weeks after pituitary apoplexy (PA). Surgery was performed in ten (28%) patients, and 25 (72%) were treated conservatively with good outcomes. No AIP mutation was found in this cohort. Conclusion: Patients with stable neuroophthalmological impairments can be treated conservatively if no significant visual loss is present. Our radiological findings suggest that hematoma absorption lasts more than that observed in other parts of the brain. Additionally, our study suggests no benefits of AIP mutation screening in sporadic patients with apoplexy.

ABSTRACT

RESUMEN Antecedentes: la cervicotomía de Kocher ha sido el abordaje clásico para la cirugía tiroidea y paratiroidea. El aumento en la preocupación por la cicatriz cervical ha generado un interés creciente por disminuir su tamaño o trasladarla a lugares menos visibles. Anuwong publica 60 casos de TOETVA/TOEPVA en 2016, con resultados óptimos. Objetivos: comunicar la experiencia con la tiroidectomía y paratiroidectomía transoral endoscópica con abordaje vestibular en el Hospital Universitario Austral. Material y métodos: análisis retrospetivo, sobre base prospectiva, de 18 procedimientos, entre mayo de 2019 y marzo de 2020. Se realizaron 2 paratiroidectomías, 13 lobectomías, 4 tiroidectomías totales, una con linfadenectomía central; una paciente presentó 2 patologías (adenoma paratiroideo y nódulo tiroideo). Citología según Bethesda: categoría II: 7; indeterminada: 1 y categoría VI: 9. Resultados: 18 pacientes femeninas. Mediana de edad: 41 años. Media del tamaño nodular: 30 mm. Volumen glandular medio: 24 mL. Conversión: 1 caso. Promedio de tiempo quirúrgico: lobectomía, 260 minutos; tiroidectomía total, 262 minutos. Histología definitiva: carcinoma papilar, 11; bocio nodular, 6; adenoma paratiroideo, 2. Complicaciones: equimosis leve, 12 pacientes; hipoparatiroidismo transitorio, 1 caso; paresia recurrencial transitoria, 1 caso; hiposensibilidad mentoniana transitoria, 1 caso. Dos casos de tiroidectomía total por cáncer: tiroglobulina a las 6 semanas < 0,1 μUI/mL. Conclusiones: 1) Es un abordaje seguro y ofrece resultados cosméticos excelentes. 2) Puede implementarse con equipamiento endoscópico convencional, con curva de aprendizaje corta y escasa morbilidad. 3) Alternativa para el tratamiento del carcinoma papilar de bajo riesgo. 4) Es prioritario garantizar la seguridad del paciente.


ABSTRACT Background: Kocher's cervicotomy has been the classic approach for thyroid and parathyroid surgery. The greater concern about neck scarring has generated an increasing interest in reducing scar size or leaving the scar in less visible places. In 2016 Anuwong published 60 cases of TOETVA/TOEPVA with optimal outcomes. Objectives: The aim of this study is to report the initial experience with transoral endoscopic thyroidectomy and parathyroidectomy vestibular approach in Hospital Universitario Austral. Material and methods: We conducted a retrospective analysis of 18 prospective procedures performed between May 2019 and March 2020. The procedures performed were 2 parathyroidectomies, 13 lobectomies, 4 total thyroidectomies, 1 with central lymph node dissection; one patient presented a parathyroid adenoma and a benign thyroid nodule. Cytology report according to the Bethesda system: category II in 7 cases, VI in 9 and indeterminate in 1. Results: 18 female patients. Median age: 41 years. Mean nodule size: 30 mm. Mean gland volume: 24 mL. Conversion. 1 case. Mean operative time: lobectomy, 260 minutes; total thyroidectomy, 262 minutes. Definite histology: papillary thyroid carcinoma,11; benign nodular goiter, 6; parathyroid adenoma, 2. Complications: mild ecchymosis, 12 patients; temporary hyperparathyroidism, 1 case; temporary recurrent laryngeal palsy, 1 case; temporary numbness of the mental region in 1 case. In the two cases undergoing total thyroidectomy due to cancer, thyroglobulin level 6 weeks after surgery was < 0.1 μIU/mL. Conclusions: 1) The transoral approach is a safe and feasible procedure that offers excellent cosmetic results. 2) It can be implemented using conventional endoscopic equipment, has a short learning curve and low morbidity rate. 3)It constitutes an alternative for the treatment of low-risk papillary thyroid carcinoma. 4) Patient's safety should be guaranteed.

ABSTRACT

Sellar plasmacytomas are rare tumors arising from plasma cells. They are often misdiagnosed as adenomas.We report the case of a 63-year-old woman with headache, cranial nerve III palsy and decreased visual acuity. Imaging revealed an extensive lesion centered on the clivus, extending to the cavernous sinus bilaterally and into the sphenoid sinus. The hormonal tests were compatible with panhypopituitarism and mild hyperprolactinemia. The first hypothesis was invasive pituitary adenoma. Partial resection was achieved, and the immunohistochemical evaluation was compatible with plasmacytoma. After a few weeks, she developed lumbar and hip pain, and the imaging confirming osteolytic lesions. The final diagnosis was multiple myeloma.

ABSTRACT

Introduction The endoscopic endonasal transsphenoidal approach (EETA) is routinely used to treat sellar and suprasellar tumors. It provides safe and direct access to tumors in these locations, with wide visualization of anatomical landmarks and great surgical results. With the COVID-19 pandemic, despite the high risk of transmission involved, various surgical procedures cannot be postponed due to their emergency. Case Report A 62-year-old female presented in the previous two months with headaches, followed by bilateral severe visual loss. In 2016, she was submitted to subtotal resection of a non-secretorymacroadenoma. Because of the progressive visual deficits, the EETA was used to the resect the pituitary adenoma. Technical Note We developed a low-cost adaptation to the surgical fields, covering the patient's head and superior trunk with a regular surgicalmicroscope bag with a tiny slit to enable the endoscope and surgical instruments to enter the nose, thus protecting the personnel in the operating room from the aerosolization of particles. This makes surgery safer for the surgical team and for the patient. Conclusion In view of the lack of literature on this subject, except for some reports of experiences from some services around the world, we describe the way we have adjusted the EETA in the context of the COVID-19 pandemic.

ABSTRACT

Resumen: Introducción: el hiperparatiroidismo primario por un adenoma gigante de paratiroides es infrecuente. Los adenomas de mayor tamaño reportados ocurrieron sobre paratiroides ectópicas (mediastinales). Comparte con el carcinoma su gran tamaño y elevadas cifras de calcemia y de hormona paratiroidea, hecho que dificulta el diagnóstico. Su tratamiento quirúrgico es la paratiroidectomía mediante una cervicotomía transversa centrada en la región infrahioidea. Objetivo: presentar un caso clínico de hiperparatiroidismo primario por un adenoma gigante de paratiroides tratado quirúrgicamente mediante un abordaje selectivo. Caso clínico: paciente de 53 años, sexo femenino, con antecedentes de litiasis ureteral, dolores óseos y tumoración infrahiodea de 4 cm de diámetro que imagenológicamente presentó las características de un adenoma paratiroideo inferior izquierdo. La valoración funcional confirmó hiperparatiroidismo. Con diagnóstico de hiperparatiroidismo primario por adenoma gigante se trató quirúrgicamente a través de una incisión pequeña y centrada en la tumoración, realizándose la paratiroidectomía inferior izquierda con la cual remitió la sintomatología y normalizó la funcionalidad paratiroidea. Discusión: el hiperparatiroidismo primario por adenoma gigante de paratiroides tiene indicación quirúrgica y es curativo. El caso presentado demuestra la factibilidad y seguridad de un abordaje selectivo a lo que suma una menor afectación cosmética, dejando indemne la logia tiroidea contralateral ante futuras cirugías sobre ésta.


Summary: Introduction: primary hyperparathyroidism caused by giant parathyroid adenoma is a rather unusual condition. Reported large adenomas occurred in ectopic parathyroid glands (mediastinal). Just like carcinomas, they are large, present high calcemia and parathyroid hormone values, what complicates diagnosis. Surgical treatment consists in parathyroidectomy by means of transversal cervicotomy around the infrahyoid region. Objective: the study presents the clinical case of primary hyperparathyroidism caused by giant parathyroid adenoma that was treated by selective surgery approach. Clinical case: 53 year-old female patient with a history of uretheral lithiasis, bone pain and 4-cm-diameter infrahyoid tumor. Imagenology studies revealed the characteristics of lower left parathyroid adenoma. Functional assessment confirmed hyperparathyroidism. Upon the diagnosis of primary hyperparathyroidism caused by giant parathyroid adenoma it was surgically addressed by means of a small cut around the tumour and performing a lower left parathyroidectomy, what resulted in the remission of symptoms and normalized parathyroid functionality. Discussion: primary hyperparathyroidism caused by giant parathyroid adenoma has an indication for surgery and is therapeutic. The case presented shows the feasibility and safety of a selective approach, as well as its smaller cosmetic harm, managing to keep the contralateral thyroid loggia intact, in view of future surgeries involving it.


Resumo: Introdução: o hiperparatireoidismo primário devido a adenoma de paratireoide gigante é raro. Os maiores adenomas relatados ocorreram em paratireoides ectópicas (mediastinais). Compartilha com o carcinoma seu grande tamanho e altos níveis de cálcio e hormônio da paratireoide, o que torna o diagnóstico difícil. Seu tratamento cirúrgico é a paratireoidectomia por meio de cervicotomia transversa com foco na região infra-hióidea. Objetivo: apresentar um caso clínico de hiperparatireoidismo primário por adenoma gigante da paratireoide tratado cirurgicamente por abordagem seletiva. Caso clínico: paciente do sexo feminino, 53 anos, com história de litíase ureteral, dor óssea e tumor infra-hióideo de 4 cm de diâmetro que apresentava características de imagem de adenoma de paratireoide inferior esquerdo. A avaliação funcional confirmou hiperparatireoidismo. Com diagnóstico de hiperparatireoidismo primário por adenoma gigante, foi tratada cirurgicamente por meio de pequena incisão focada no tumor, realizando paratireoidectomia inferior esquerda com remissão dos sintomas e normalização da funcionalidade da paratireoide. Discussão: o hiperparatireoidismo primário devido ao adenoma gigante da paratireoide tem indicação cirúrgica e é curativo. O caso apresentado demonstra a viabilidade e segurança de uma abordagem seletiva que apresenta um menor envolvimento estético, deixando o espaço contralateral da tireoide sem danos para futuras cirurgias.
