RESUMO

RESUMEN La diverticulitis apendicular (DA) es una patología poco frecuente, considerada clínicamente indistinguible de la apendicitis aguda, aunque podría presentar una sintomatología más leve. Este es el caso de un paciente masculino de 59 años, que concurre al Servicio de Urgencias presentando signos y síntomas sugestivos de una apendicitis aguda; una ecografía informa un asa tubular parcialmente compresible de 7,8 mm de diámetro y una fina banda de líquido laminar, compatible con proceso apendicular agudo. La apendicectomía se realizó de manera convencional evidenciándose un apéndice inflamado principalmente en su región distal. La histología reveló diverticulitis apendicular complicada con rotura. El paciente evolucionó favorablemente y se externó a las 24 horas. Existe una asociación de DA y neoplasia apendicular, por lo que se recomienda una colonoscopia y el seguimiento de este tipo de pacientes.

ABSTRACT Appendiceal diverticulitis (AD) is a rare condition considered clinically identical to acute appendicitis although it may present milder symptoms. We report the case of a 59-year-old male patient who visited the emergency department due to signs and symptoms suggestive of acute appendicitis. An abdominal ultrasound showed partially compressible tubular loop with a diameter of 7.8 mm and a thin band of laminar fluid, consistent with acute appendiceal process. During conventional appendectomy the appendix had signs of inflammation, mainly in the distal region. The histology revealed appendiceal diverticulitis complicated with rupture. The patient had favorable outcome and was discharged 24 hours later. As, there is a clear association between AD and appendiceal neoplasms, colonoscopy and patient monitoring is recommended.

RESUMO

RESUMEN Antecedentes: con el advenimiento de los abordajes mininvasivos se han planteado diferentes escenarios; la paratiroidectomía transoral endoscópica por abordaje vestibular (TOEPVA) es una técnica con resultados prometedores. Objetivos: describir la técnica quirúrgica y la experiencia obtenida. Material y métodos: se seleccionaron 3 pacientes asintomáticos con hiperparatiroidismo primario por adenoma paratiroideo y un caso de hiperparatiroidismo terciario con hiperplasia paratiroidea clínica e imagenológicamente identificables. Resultados: en 3 de los pacientes, el tiempo quirúrgico fue de 202,5 minutos. La tolerancia al dolor fue buena y la internación abarcó 24 horas. En uno de los casos con adenoma paratiroideo de ubicación ectópica se realizó la conversión de la cirugía con una apertura esofágica accidental. En todos los casos se obtuvo un descenso de parathormona intraoperatoria superior al 50% sobre el basal. Conclusiones: creemos importante aplicar dicho procedimiento en casos seleccionados, pues es una alternativa mininvasiva reproducible aunque no exenta de complicaciones.

ABSTRACT Background: Different scenarios have emerged with the advent of minimally invasive approaches; transoral endoscopic parathyroidectomy vestibular approach (TOEPVA) is a technique with promising results. Objective: The aim of this study is to describe the surgical technique and the experience gained. Material and methods: We describe 3 patients with asymptomatic primary hyperparathyroidism due to parathyroid adenoma and one case of tertiary hyperparathyroidism with parathyroid hyperplasia with clinical signs and presence of lesions in imaging tests. Results: In 3 patients operative time was 202.5 minutes. The patients had adequate tolerance to pain and remained hospitalized for 24 hours. One patient with ectopic parathyroid adenoma required conversion to open surgery that was complicated with an accidental esophageal injury. Intraoperative parathormone levels decreased by > 50% compared by baseline values in all the cases. Conclusions: This minimally invasive procedure is reproducible but should be used in selected cases as it is not free of complications.

RESUMO

BACKGROUND: The Kidney Donor Profile Index (KDPI) was created in 2014 to measure the likelihood of graft failure for a given donor compared with the median kidney donor from the previous year. This scale is based on the American population only. Mexico is one of the countries with greater incidence of chronic kidney disease, a long waiting list, and not enough kidney donors with KDPI smaller than 80%. This has led transplant centers to take kidney grafts with a higher KDPI. OBJECTIVE: To investigate the agreement between the KDPI and histologic scores (preimplantation renal biopsy) and assess the relationship between the Kidney Donor Risk Index (KDRI), KDPI, and the histologic score on graft survival. METHODS: A retrospective, analytical, transversal study was performed. Data were collected from patients with kidney grafts from deceased donors from January 1, 2011, to June 30, 2019, at our hospital. The variables analyzed were age, weight, height, sex, race and/or ethnicity, history of hypertension or diabetes, cause of death, serum creatinine, KDPI, KDRI, and biopsy result from each graft prior to transplant. RESULTS: The total population was 59 deceased kidney donors. For our patients, a high KDPI did not increase mortality rate; it provided greater benefit than staying on dialysis. CONCLUSIONS: We conclude that the use of KDRI should only be considered to assess the degree of fibrosis, not to rule out a transplantable kidney, in addition to the consistent demonstration that high KDPI kidneys (even 91%-100%) confer greater survival benefits to patients regarding the waiting list.

RESUMO

La cirugía endoscópica transluminal a través de orificios naturales (NOTES) ha sido aplicada por primera vez por K. Witzel en el año 2008, introduciendo el abordaje transoral para la patología tiroidea en cadáveres y puercos. En el año 2016, A. Anuwong publicó la primera serie de casos en seres humanos por abordaje vestibular. Referimos en esta ocasión el caso de una paciente de 37 años, quien acudió a la consulta por presentar una tumoración cervical anterior de dos meses de evolución. Ecografía tiroidea con bocio polinodular. Punción aspiración con aguja fina: lesión con hiperplasia folicular en lóbulo derecho e izquierdo. Se decide realizar tiroidectomía transoral endoscópica por abordaje vestibular. La duración de la intervención fue de 180 minutos, la pérdida sanguínea fue de 20 mL. El dolor, escaso y el tiempo de internación, 36 horas. En el presente trabajo se propone el desarrollo de esta técnica y la experiencia en nuestro primer caso de tiroidectomía total en patología tiroidea benigna.

Natural orifice transluminal endoscopic surgery (NOTES) was applied for the first time by K. Witzel in 2008, introducing the transoral endoscopic resection of the thyroid gland in human cadavers and living pigs. In 2016, A. Anuwong published the first case series using the vestibular approach in humans. We report the case of a 37-year-old female patient with a mass in the anterior aspect of the neck which appeared two months before consultation. The thyroid ultrasound reported multinodular goiter. The fine-needle aspiration (FNA) biopsy reported hyperplastic follicular nodule in both lobes. The patient underwent transoral endoscopic thyroidectomy by vestibular approach. Operative time was 180 minutes and blood loss was 20 mL. Pain was minimal and hospital stay was 36 hours. We report our first experience with total thyroidectomy in a patient with benign thyroid nodules.
