Mid- to long-term results of SuPerLap single-port treatment in inguinal hernia. / Resultados a medio-largo plazo del tratamiento monopuerto SuPerLap de la hernia inguinal.

INTRODUCTION: Laparoscopic treatment of inguinal hernia is gaining popularity in many hospitals, but the use of working channel scopes is not as widely extended. We present our long-term experience with the SuPerLap (laparoscopic-assisted percutaneous suture) technique described by Rosell et al.(1) for epigastric hernia repair in the percutaneous, single-port treatment of inguinal hernia using working channel scopes. MATERIALS AND METHODS: A retrospective analysis of a series of male patients with congenital inguinal hernia undergoing surgery from February 2017 to December 2020 was carried out. A 5 mm-0º pleuroscope with a 3.5 mm working channel, a 20 G epidural needle, a 36 cm/3.5 mm laparoscopic Maryland dissector, and 3-0 polypropylene and polyester sutures were used. RESULTS: 384 inguinal hernia repairs using the SuPerLap technique were performed in 295 male patients - 206 unilateral repairs and 89 bilateral repairs. In 24 bilateral cases (26.95%), preoperative diagnosis had been unilateral. Mean age was two years (2 weeks-13 years). Mean operating time was 14 minutes (6-50 min) for unilateral repair, and 27 minutes (14-80 min) for bilateral repair. There were two cases of epigastric vessel damage, and one case of early recurrence in a newborn, who successfully underwent re-intervention using the SuPerLap technique. No late complications were recorded after a mean follow-up of 1-36 months. CONCLUSIONS: Working channel scopes using the SuPerLap technique avoid additional ports in inguinal hernia repair. They allow for excellent functional results, without visible scars, and minimize spermatic cord manipulation. Laparoscopy allows previously undiagnosed defects to be concomitantly treated.

INTRODUCCION: La laparoscopia en el tratamiento de la hernia inguinal está cada vez más presente en muchos hospitales. El uso de ópticas con canal de trabajo no está tan extendido. Se presenta la experiencia a largo plazo en la aplicación de la técnica SuPerLap (sutura percutánea laparoasistida) propuesta por Rosell y cols.(1) para la reparación de hernias epigástricas en el tratamiento monopuerto, percutáneo de las hernias inguinales mediante el uso de ópticas con canal de trabajo. MATERIAL Y METODO: Serie quirúrgica de hernia inguinal congénita en varones (febrero de 2017-diciembre de 2020). Se utilizó: pleuroscopio de 5 mm-0º con canal de trabajo de 3,5 mm; aguja epidural 20 G; suturas de polipropileno y poliéster 3/0; disector Maryland laparoscópico (36 cm-3,5 mm). RESULTADOS: Se realizaron 384 herniorrafias inguinales según técnica SuPerLap en 295 varones (206 unilaterales, 89 bilaterales). En 24 casos bilaterales (26,95%) el diagnóstico preoperatorio fue unilateral. La edad media fue de dos años (2 semanas-13 años). El tiempo medio quirúrgico fue 14 minutos (6-50 min) en unilaterales, 27 (14-80 min) en bilaterales. Hubo dos casos de lesión de vasos epigástricos y una recidiva precoz en un neonato, reintervenido satisfactoriamente mediante técnica SuPerLap. En un seguimiento de 1-36 meses no hubo complicaciones tardías. CONCLUSIONES: El uso de ópticas con canal de trabajo según técnica SuPerLap posibilita prescindir de puertos adicionales en el tratamiento de la hernia inguinal. Permite resultados funcionales comparables y cirugía sin cicatrices visibles. Minimiza la manipulación del cordón espermático. La laparoscopia permite el tratamiento concomitante de defectos no diagnosticados previamente.

The potential role of microRNAs as biomarkers in atopic dermatitis: a systematic review.

OBJECTIVE: Reliable biomarkers are required for clinical use in atopic dermatitis (AD). MicroRNAs are mediators of post-transcriptional gene silencing, and specific expression patterns are being characterized in AD. To assess whether microRNAs could be useful biomarkers for clinical use in patients with AD. MATERIALS AND METHODS: Systematic review of all articles identified in SCOPUS and PubMed through the PRISMA statement. Literature was summarized in narrative form and results are presented per category. RESULTS: From a total of 118 identified references 11 manuscripts were included for qualitative analysis, after selecting them according to the eligibility criteria. An aberrant expression of microRNAs characterizes AD, which facilitates T cell polarization towards a Th17 phenotype, especially miR-155. There is also altered regulation of Th1/Th2 phenotypes by overexpression of miR-151a. The aberrant keratinocyte function observed in AD could also be due to altered expression of microRNAs, specifically miR-146a, miR-143 and miR-29. Finally, miR-203 may reflect the extent of inflammation in AD, in parallel with the tumor necrosis factor pathway and immunoglobulin E levels. CONCLUSIONS: MicroRNAs are easily identifiable molecules in a variety of cells and body fluids that may be useful as diagnostic (miR-155 and miR-146a) and disease severity (miR-203) biomarkers in patients with AD.

[Testicular epidermoid cyst: uncommon lesion of difficult preoperative diagnosis]. / Quiste epidermoide testicular: una rara entidad de dificil diagnostico preoperatorio.

Intratesticular epidermoid cysts are rare tumours that constitute one percent of all testicular masses. They are bening lesions that make differential diagnosis from malignant testicular tumours difficult. The absence of serum markers elevation and ultrasound imaging could support these lesions being bening epidermoid cysts, and in that case, conservative surgery is adequate. We present the case of a 22 years old patient who complains of a left testicular mass. In this case ultrasound diagnosis was non-specific and a left radical inguinal orchiectomy was performed.

Quiste epidermoide testicular: una rara entidad de difícil diagnostico preoperatorio / Testicular epidermoid cyst: uncommon lesion of difficult preoperative diagnosis

Los quistes epidermoides intratesticulares son tumores raros, constituyendo el 1% de todos los tumores testiculares. Se trata de tumoraciones benignas que plantean un difícil diagnóstico diferencial preoperatorio frente a los tumores malignos testiculares. La ausencia de elevación de los marcadores tumorales y la apariencia ecográfica, pueden orientar hacia su diagnóstico preoperatorio y en este caso la cirugía conservadora del testículo. Se presenta el caso de un paciente de 22 años que consulta por una masa en el testículo izquierdo. En este caso, el diagnóstico ecográfico preoperatorio no descartaba otras patologías por lo que se procedió a la realización de orquiectomía inguinal izquierda (AU)

[Usefulness of abdominal leak point pressure determination in the diagnosis of female urinary incontinence in the TVT era]. / Utilidad de la determinación de la presión abdominal de fuga en el diagnóstico de la incontinencia de orina femenina en la epoca del TVT.

OBJECTIVE: To analyse our results about continence in the treatment of female urinary incontinence with the tension-free vaginal tape (TVT) procedure based on abdominal leak point pressure(ALPP). PATIENTS AND METHODS: Retrospective study of the fifty two patients who had urodynamic study and abdominal leak point pressure determination and were operated on between 1999 and 2002 for stress urinary incontinence. We reviewed the data of clinical history, physical examination and urodynamic report, surgery, complications, and objective and subjective results. Those patients having ALPP > 100 are included in group 1, between 61 and 100 in group 2 and less than 60 in group 3. RESULTS: There were 19 patients in group 1, 17 in group 2 and 16 in group 3. We found no difference between the three groups regarding age, delivery, menopause, hysterectomy, evolution, previous surgery, grade of cystocele, association of anterior colporraphy to TVT and type of anaesthesia. The Obrink clinical grade increased as the ALPP decreased (grade 3 in 26.32% of group 1, 31.58% in group 2 and 68.71% in group 3). 100% of patients in groups 1 and 2 were continent with effort and 93.75% in group 3. Complications, especially de novo instability or urgency-frequency episodes or persistence of instability in patients having mixed incontinence, caused a decrease in the satisfaction degree to 79% in group 1, 76.5% in 2 and 62.5% in 3. CONCLUSIONS: Abdominal leak point pressure determination does not change our decision of perform a TVT procedure but permits us to differentiate one group in which results could be worse.

Utilidad de la determinación de la presión abdominal de fuga en el diagnóstico de la incontinencia de orina femenina en la época del TVT / Usefulness of abdominal leak point pressure determination in the diagnosis of female urinary incontinence in the TVT era

OBJETIVO: Analizar los resultados del tratamiento de la incontinencia de esfuerzo tratada con TVT en función de la presión abdominal de fuga (PAF). MATERIAL Y MÉTODO: Estudio retrospectivo de 52 pacientes operadas entre 1999 y 2002 que tenían estudio urodinámico y determinación de la PAF, con seguimiento mínimo de 3 meses. Se analizan las características clínicas y resultados respecto de la desaparición de la incontinencia al esfuerzo como de la sensación subjetiva y satisfacción de las pacientes. Denominamos grupo 1 si la PAF>100; grupo 2 entre 61 y 100; y grupo 3 si la PAF<60. RESULTADOS: En el grupo 1 había 19 pacientes, 17 en el 2 y 16 en el 3. No existieron diferencias entre los 3 grupos respecto a la edad, paridad, menopausia, histerectomía, años de evolución, cirugía previa, presencia y grado de cistocele, asociación de colporrafia al TVT y tipo de anestesia utilizada. El grado clínico de Obrink aumentó a medida que disminuía la PAF (grado 3 en 26,32% del grupo 1; 31,58% del 2 y 68,71% del 3).La continencia al esfuerzo se consiguió en el 100% de las pacientes de los grupos 1 y 2, y en el 93,75% del grupo 3. La aparición de complicaciones, especialmente inestabilidad de novo o cuadros de urgencia-frecuencia así como la persistencia de inestabilidad en algunos casos de incontinencia mixta, hizo que el grado de satisfacción de las pacientes fuese del 79% en el grupo 1, 76,5% en el 2 y del 62,5% en el 3. CONCLUSIONES: La determinación de la PAF no parece influir en la decisión de implantar un TVT, pero sí permite diferenciar un grupo (PAF<60 cm de agua) cuyos resultados esperados son ligeramente peores

[Upper urinary tract tumours]. / Tumores de urotelio superior.

OBJECTIVE: To evaluate diagnostic techniques, treatment and follow-up in 94 patients affected of upper urinary tract tumor. PATIENTS AND METHOD: From 1978 to december 2002 we operated 105 patients due to upper urinary tract tumor, although only 94 are valid for analysis. Mean age was 65 years and 85% were man. Haematuria was the most frequent symptom. RESULTS: Urography (93%), ecography (77%) and CT (67%) were the most used diagnostic techniques. Pelvic tumor was the most frequent (71%) and total nephroureterectomy including bladder cuff the chosen treatment (76.4%). Previous or simultaneous bladder tumor was observed in 23% cases and delayed in 30%. With a mean follow-up of 76 months the patient survival is 53%. CONCLUSIONS: Due to the high frequence of previous, simultaneous or delayed bladder tumors, the upper urinary tract tumor should be considered as a panurothelial disease, worsening the outcome of this kind of tumors.

Tumores de urotelio superior / Upper urinary tract tumours

OBJETIVOS: Evaluar los métodos diagnósticos empleados, el tratamiento y el seguimiento de los pacientes afectos de tumor de urotelio superior. PACIENTES Y MÉTODO: Desde 1978 hasta diciembre de 2002 han sido operados 105 pacientes afectos de tumor de urotelio superior, siendo válidos para el análisis 94. La edad media ha sido de 65 años, siendo el 85 por ciento varones. La hematuria fue el síntoma más frecuente de presentación. RESULTADOS: Se realizó UIV en el 93 por ciento de los pacientes, la ecografía en el 77 por ciento y el TAC en el 67 por ciento. Predominó el tumor piélico (71 por ciento) y el tratamiento mayoritario fue la nefroureterectomía total con resección del collarete vesical perimeatal (76,4 por ciento). El tumor vesical previo o simultáneo se constató en 22 casos (23,3 por ciento) y posterior en 28 casos (30 por ciento). Con un seguimiento medio de 76 meses, la supervivencia es del 53 por ciento. CONCLUSIONES: El tumor de urotelio superior debe considerarse como una enfermedad panurotelial debido a la alta frecuencia de tumor vesical previo, simultáneo o posterior, lo cual empeora aún más el pronóstico de esta enfermedad (AU)

[Corrective surgery of penile inward curvature]. / Cirugía correctora de la incurvación peneana.

OBJECTIVE: To evaluate the corporoplasty techniques performed on 59 patients to correct congenital penile curvature and Peyronie's disease. PATIENTS AND METHOD: From april 1991 to december 2001, 39 Nesbit technique, 12 Ruiz-Castañé method and 8 Essed-Schröeder procedure were performed on forty-four congenital curvatures and fifteen Peyronie's diseases. The mean age was 24 years old. Trying to hide the knots, in all patients except five a nonabsorbable inverting sutures were placed. RESULTS: The mean follow-up was 12 months. Postoperatively, 53 patients (86%) had satisfactory cosmetic and functional results. Four patients of five with absorbable sutures had residual curvature which needed another successful surgical correction. One patient complained of penile shortening, one of glans hypoaesthesia, one of foreskin oedema and five of palpable plication sutures. No differences were found depending on the applied surgical technique. CONCLUSIONS: The results reported are in accordance with the literature showing a higher recurrence rate with the absorbable sutures. The outcome is very similar with the three described techniques.

Cirugía correctora de la incurvación peneana / Corrective surgery of penile curvature

OBJETIVOS: Evaluar las técnicas de corporoplastia aplicadas a 59 pacientes afectos de incurvación peneana, tanto congénita como adquirida. PACIENTES Y MÉTODO: Desde abril de 1991 hasta diciembre del 2001 se aplicaron 39 técnicas de Nesbit, 12 de Ruiz-Castañé y 8 de Essed-Schröeder en 44 pacientes con incurvación congénita y 15 con enfermedad de Peyronie (edad media de 25 años). En cinco casos se utilizó material reabsorbible y en el resto irreabsorbible, aplicando puntos invertidos para enterrar los nudos. RESULTADOS: Con un seguimiento medio de 12 meses se ha obtenido la corrección de la incurvación en el 86 por ciento de los casos. Cuatro de los cinco casos en que se utilizó material reabsorbible requirieron segunda intervención por reincurvación. Un caso de acortamiento de pene, otro de hipoestesia glandar, un edema prolongado prepucial y cinco casos de palparse los puntos fueron las complicaciones más reseñables. No se observaron diferencias en cuanto a resultados y complicaciones según la técnica empleada. CONCLUSIONES: Con las tres técnicas empleadas se ha obtenido un buen resultado cosmético y funcional, que coincide con las series publicadas en la literatura. Preferimos la sutura irreabsorbible para evitar el alto índice de reincurvaciones con el material absorbible (AU)

[Complications in a consecutive series of 133 cases of radical prostatectomy]. / Complicaciones de una serie consecutiva de 133 casos de prostatectomía radical.

OBJECTIVE: To evaluate the surgical complications of radical prostatectomy in our hospital. PATIENTS AND METHOD: From august 1991 to december 1999, 138 patients with clinically localized prostate cancer underwent Walsh technique radical prostatectomy. The follow-up is known from 133 patients with a mean age of 64.8% and a mean PSA of 17.6 ng/ml. RESULTS: The mean follow-up is 43 months. Urinary fistula (9%), lymphatic leakage (5.22%) and rectal injury (2.2%) are the most common early complications. Urinary incontinence (27%), erectile dysfunction (98%) and urethrovesical junction stenosis (12%) are the delay complications. Only three patients have died due to prostate cancer. Our results are compared with another series. CONCLUSIONS: The morbidity of radical prostatectomy is very similar to the compared series. Urinary incontinence and erectile dysfunction are the most worrying complications which the patient must know to have the opportunity to choose another therapeutic option.

Complicaciones de una serie consecutiva de 133 casos de prostatectomía radical / Surgical complications in a consecutive succession of 133 cases of radical prostatectomy

OBJETIVO: Evaluar las complicaciones quirúrgicas de la prostatectomía radical (PR) en nuestro medio. PACIENTES Y MÉTODO: Desde agosto de 1991 a diciembre de 1999, hemos realizado 138 PR en pacien-tes con adenocarcinoma de próstata (CaP) clínicamente localizado. Analizamos sólo los 133 casos de los que conocemos la evolución. La técnica utilizada ha sido la ascendente descrita por Walsh por vía retropúbica. La edad media era de 64,8 y la media del PSA era de 17,6 ng/ml. RESULTADOS: Con un seguimiento medio de 43 meses diferenciamos las complicaciones precoces de las tardías. Entre las primeras tenemos la fístula urinaria (9 por ciento), la linforrea (5,22 por ciento) y la lesión rectal (2,2 por ciento).De las tardías la más preocupante es la incontinencia de orina (27 por ciento) de la que el 4,5 por ciento es grave. La más frecuente es la disfunción eréctil (98 por ciento) y la estenosis de la anastomosis (12 por ciento) es la menos preocupante. Sólo tres pacientes han fallecido debido a la neoplasia. Comparamos nuestros resultados con las series más amplias nacionales y extranjeras. CONCLUSIONES: La cirugía radical de próstata en nuestro medio tiene una morbilidad similar a otras series. La incontinencia urinaria y la disfunción eréctil son las secuelas más preocupantes que los pacientes deben conocer para decidir otras opciones terapéuticas (AU)

[Leydig cell tumor. Report of 2 cases and review of the literature]. / Tumor de células de Leydig. Aportación de dos casos y revisión de la literatura.

The Leydig cell tumor is the most frequent of non-germ cell tumors of the testis. Clinical findings depend on the age of presentation. We present two cases of Leydig Cell tumors of the testis, diagnosed in a 8 years old child with isosexual precocity, and a 42 years old adult with Gynaecomastia. After reviewing the existing literature on this uncommon pathology we consider that the iconography presented is very interesting for furthering the knowledge on this subject.

[Correlation between imaging findings and anatomopathologic results in radical prostatectomy. Data from our series]. / Correlación de los hallazgos por imagen y resultados anatomopatológicos en la prostatectomía radical. Datos de nuestra serie.

OBJECTIVE: To analyze the diagnostic methods utilized in prostate cancer and the preoperative information on the extent of the tumor, and compare these results with those obtained from anatomopathological analyses of the radical prostatectomy specimen. METHODS: Data on the radical prostatectomies performed during the study period were obtained from the Admissions and Clinical Records services and were analyzed using the SPSS statistical analysis software for Windows. RESULTS: From 1991 to 1998, 109 radical prostatectomies were performed. Evaluation by transrectal US was carried out in 89 patients (81.6%) and detected a tumor (unilateral or bilateral) in 77, for a sensitivity of 86% (CI 78.8-93.2). A CT study was performed in 94 patients and was positive in 25, for a sensitivity of 26.5% (CI 17.6-35.4). The sensitivity for transrectal US and CT were 4.17% and 3.33% for capsular involvement, 5.88% and 5.26% for seminal vesicle involvement, and 0% and 0% for node involvement, respectively. CONCLUSIONS: Transrectal ultrasound is a reliable diagnostic imaging method, although it has a low sensitivity when used to determine the extent of the tumor. In our series, the radiological methods showed a low sensitivity when they were utilized to determine the extent of the prostate cancer. Routine preoperative assessment by CT can be obviated in prostate cancer.

[Incidence of priapism at the Marqués de Valdecilla University Hospital in Santander]. / Incidencia de priapismo en el Hospital Universitario Marqués de Valdecilla de Santander.

OBJECTIVE: Our experience in the management of priapism, its etiology, blood gas changes, treatment and outcome are presented. METHODS: The records of patients that had been treated at the Urology services of our hospital over the last 8 years were reviewed. During this period, patients with erectile dysfunction were treated according to a protocol. RESULTS: There were 9 episodes of priapism in 8 patients; all cases were low flow and the patients were aged 37-71 years. The duration of the prolonged erection ranged from 4 to 72 hours. Of these 9 cases, the etiology was intracavernosal PGE in 7, after trazodone administration in one case, and unknown in one case. Intracavernosal metoxamine was administered in all cases with excellent results, except one case that required a saphenous-cavernosal shunt and another case that was initially treated with adrenalin also with good results. CONCLUSIONS: Since intracavernosal agents have been utilized in the treatment of erectile dysfunction, priapism has become a more frequent urological emergency. Although a lower incidence has been reported for PGE, the dose should be well adjusted to avoid a higher incidence.
