Response to "Stomal varices: an unusual cause of bleeding due to portal hypertension".

We have considered the opportunity to add some remarks about the management and treatment of bleeding due to stomal varices, after reading the article written by López-Couceiro et al, in which our previous article is referred.

Ureteroiliac Fistula: Bleeding of Unknown Origin-Case Report and Review of the Literature.

Background: Ureteroiliac fistula is a rare cause of gross hematuria and lateralizing flank pain. Risk factors include previous pelvic surgery, pelvic radiotherapy, or chronic ureteral stentings. Diagnosis is challenging and requires arteriography and ureteroscopy. Management ranges from open surgery to minimally invasive means such as the use of an endovascular stent. Case Report: A 62-year-old man with postradical cystoprostatectomy and cutaneous ureterostomy presented an intermittent gross hematuria with anemia that required blood transfusions. Some CT arteriographies were performed but none of them could identify the bleeding origin. Therefore, a flexible ureteroscopy was performed that showed a left ureteroiliac fistula. Subsequently, an endovascular stent was placed in the left common iliac without complications. Conclusion: The ureteroiliac fistula is a life-threatening condition. CT arteriography or ureteroscopy might help in the diagnosis but the sensitivity is ∼64%. Arteriography with endovascular stenting is a viable and safe option. However, because of its rarity, long-term durable benefits still need to be documented.

[Video endoscopic inguinal lymphadenectomy in penile cancer: Systematic review.] / Linfadenectomía inguinal videoendoscópica en cáncer de pene: revisión sistemática.

OBJECTIVES: Penile cancer is not very frequent. To control the disease oncologically, we must perform inguinal lymphadenectomy in cases of high-risk histology, poor prognosis and palpable lymph nodes. The open inguinal lymphadenectomy has a high rate of morbidity. Consequently, this systematic review intends to summarize the published literature regarding the oncologic and post-surgery outcomes in video-endoscopic inguinal lymphadenectomy (VEIL). METHODS: A literature search has conducted through Pubmed, EMBASE and Cochrane library for English and Spanish articles. RESULTS: Our literature search identified 12 articles. In total, 161 patients have been subjected to 226 VEIL. Their average age was 55.66 years. In the case of open inguinal lymphadenectomy, 90 patients have been subjected to 106 operations. The rate of cutaneous complications was 6% for VEIL and 55.6% for open lymphadenectomy. The rate of lymphatic complications was very similar in both types of lymphadenectomy. The average number of lymph nodes obtained was 9.12 for VEIL and 7.02 lymph nodes for the open approach. CONCLUSION: Video-endoscopic inguinal lymphadenectomy contributes to less morbidity with a lower- rate of cutaneous complications and less severity. Furthermore, VEIL gives lower hospital stay without changing in initial oncologic outcomes. Although we need longer series to stablish the oncologic long-term results.

OBJETIVO: El cáncer de pene es una entidad poco frecuente. Para realizar un buen control oncológico, se recomienda la realización de linfadenectomía inguinal en casos de factores de riesgo de mal pronóstico, grado histológico alto o ganglios palpables o positivos. La linfadenectomía inguinal abierta presenta una alta tasa de morbilidad, por lo que en esta revisión se pretende resumir la literatura publicada en cuanto a los resultados oncológicos y postquirúrgicos en la linfadenectomía inguinal videoendoscópica (VEIL).MATERIAL Y MÉTODOS: Se realiza revisión sistemática de la literatura obtenida en "Pubmed", "EMBASE" y Cochrane library para artículos en inglés y español. RESULTADOS: Se han analizado un total de 12 artículos, que globalmente incluyen a 161 pacientes con 226 VEIL y una edad media de 55,66 años y 90 pacientes a los que se les ha realizado 106 linfadenectomías abiertas. En el caso del VEIL se han presentado 6% de complicaciones cutáneas y del 55,6% en el caso de la vía abierta. En cuanto a las complicaciones linfáticas, no hay diferencias significativas. La media de ganglios extraídos en el caso de VEIL de 9,12 ganglios y de 7,09 ganglios en abordaje abierto. CCONCLUSIONES: La linfadenectomía inguinal videoendoscópica aporta una menor morbilidad, con una menor tasa de complicaciones cutáneas, y de menor gravedad. Asimismo, aporta menor estancia hospitalaria, sin afectación de los resultados oncológicos iniciales. Aunque se necesitan series con mayor tiempo de seguimiento para valoración de resultados oncológicos a largo plazo.

Role of the 4Kscore test as a predictor of reclassification in prostate cancer active surveillance.

BACKGROUND: Management of active surveillance (AS) in low-risk prostate cancer (PCa) patients could be improved with new biomarkers, such as the 4Kscore test. We analyze its ability to predict tumor reclassification by upgrading at the confirmatory biopsy at 6 months. METHODS: Observational, prospective, blinded, and non-randomized study, within the Spanish National Registry on AS (AEU/PIEM/2014/0001; NCT02865330) with 181 patients included after initial Bx and inclusion criteria: PSA ≤10 ng/mL, cT1c-T2a, Grade group 1, ≤2 cores, and ≤5 mm/50% length core involved. Central pathological review of initial and confirmatory Bx was performed on all biopsy specimens. Plasma was collected 6 months after initial Bx and just before confirmatory Bx to determine 4Kscore result. In order to predict reclassification defined as Grade group ≥2, we analyzed 4Kscore, percent free to total (%f/t) PSA ratio, prostate volume, PSA density, family history, body mass index, initial Bx, total cores, initial Bx positive cores, initial Bx % of positive cores, initial Bx maximum cancer core length and initial Bx cancer % involvement. Wilcoxon rank-sum test, non-parametric trend test or Fisher's exact test, as appropriate established differences between groups of reclassification. RESULTS: A total of 137 patients met inclusion criteria. Eighteen patients (13.1%) were reclassified at confirmatory Bx. The %f/t PSA ratio and 4Kscore showed differences between the groups of reclassification (Yes/No). Using 7.5% as cutoff for the 4Kscore, we found a sensitivity of 89% and a specificity of 29%, with no reclassifications to Grade group 3 for patients with 4Kscore below 7.5% and 2 (6%) missed Grade group 2 reclassified patients. Using this threshold value there is a biopsy reduction of 27%. Additionally, 4Kscore was also associated with changes in tumor volume. CONCLUSIONS: Our preliminary findings suggest that the 4Kscore may be a useful tool in the decision-making process to perform a confirmatory Bx in active surveillance management.

Outpatient holmium laser treatment for recurrent low-grade superficial bladder cancer under local anesthesia.

BACKGROUND: The aim of this paper is to analyze the results of a prospective study conducted on a cohort of patients undergoing outpatient holmium laser fulguration. The "gold standard" treatment of superficial bladder cancer is transurethral resection, although in recent years improvements in laser technology and endoscopy equipment have allowed further therapeutic alternatives. METHODS: This is a descriptive study of a cohort of 37 patients with low-risk recurrent superficial bladder cancer undergoing holmium laser fulguration after bladder instillation of local anesthesia. The study included patients with a history of low-risk primary superficial bladder cancer with papillary tumor recurrence, tumor size ≤10 mm, fewer than 5 tumors, absence of carcinoma in situ, negative cytology, no coagulation disorders and no local anesthesia allergies. Demographic variables, previous history of transurethral resection, safety and oncological results after fulguration were analyzed using the SPSS software. Statistical analyses include calculating mean and frequency, and Kaplan-Meier curve for recurrence. RESULTS: Mean age of the patients was 69.2 years with 86.5% being male. The number of tumors was 1.5±0.8 and the overall average size of 5.5±2.7 mm. The mean duration of the endoscopic procedure was 12±4.3 minutes. Hundred percent of patients had scores on the Visual Analogue Scale ≤3. There was only one case of hematuria, who required hospitalization. After a median follow-up period of 13 months, there was a 35.1% recurrence rate with one case of tumor progression. CONCLUSIONS: Holmium laser treatment of recurrent low-risk superficial bladder tumor is a safe and effective alternative, but long-term clinical trials are necessary to increase the current scientific evidence base.

Fulguración con láser de la recidiva de tumores vesicales superficiales bajo anestesia local: diseño de procesos / Laser fulguration of superficial bladder tumor recurrence under local anesthesia. design process

Introduction: The process design is one of the most interesting tools to ensure the quality of health care before the start of an activity. Although the gold standard treatment of superficial bladder tumors remains transurethral resection (TUR), the onset of laser energy source with better endourological systems allows us to adopt alternative therapies. The aim of this pilot study is to describe the design and protocol in 37 patients with a novel process consisting of outpatient treatment under local anesthesia of bladder tumors with holmium laser. Material and Methods: Pilot study includes 37 patients between January 2012 and December 2013, for the development of a process of holmium laser bladder fulguration without anesthetic infiltration in outpatient study. It analyzes and studies the procedure tolerance, development of immediate complications, visual analog scale (VAS) of pain, patient satisfaction, hospital stays avoided, problems during the application process and development. Results: The mean age of the patients was 69.2 +/- 10.3 years, 100 percent of patients prefer this procedure instead conventional transurethral resection and VAS rating presenting ≤ 3. There were no important complications. Only one patient was admitted at hospital due to hematuria resolved without surgical treatment. Conclusions: The development and implementation of fulguration of superficial papillary bladder tumors with holmium laser process is simple, well tolerated, ambulatory and without complications, with no need of hospital stay.

Introducción: El diseño de procesos es una de las herramientas de mayor interés para asegurar la calidad de la asistencia sanitaria antes del comienzo de una determinada actividad. Aunque el gold standard del tratamiento de los tumores vesicales superficiales sigue siendo la resección transuretral (RTU), la aparición de la fuente de energía láser con mejores medios endourológicos nos permite adoptar otras alternativas terapéuticas. El objetivo de este estudio piloto es describir el diseño y protocolo en 37 pacientes de un proceso novedoso consistente en el tratamiento en régimen ambulatorio y bajo anestesia local intravesical de los tumores de vejiga con láser de holmium. Material y Métodos: Estudio piloto que incluye 37 pacientes entre enero de 2012 y diciembre de 2013, para la elaboración de un proceso de fulguración vesical con láser de holmium sin infiltración anestésica en régimen ambulatorio. Se analiza y estudia tolerancia al procedimiento, desarrollo de complicaciones inmediatas, escala visual analógica (EVA) del dolor, satisfacción del paciente, estancias hospitalarias evitadas, problemas durante la aplicación del proceso y desarrollo del mismo. Resultados: La edad media de los pacientes fue 69,2 +/- 10,3 años, presentando puntuación EVA ≤ 3. No existieron complicaciones importantes. Hubo un ingreso por hematuria tardía que se resolvió de forma conservadora. Conclusiones: La elaboración y aplicación del proceso de fulguración de tumores vesicales papilares superficiales con láser holmium es una técnica sencilla, con buena tolerancia, ambulatoria y sin complicaciones de interés, con eliminación de estancias hospitalarias.

Seminal vesicle biopsies: an useful staging procedure-exposure of seminal vesicle biopsies protocol and review of the literature.

BACKGROUND AND OBJECTIVES: Although new MRI techniques have a high sensitivity but varying specificity with regard to diagnosing the seminal vesicle invasion (SVI) of prostate cancer, the low availability and high cost involved demands incorporating an inexpensive and accessible technique that might support adequate staging. Currently, uniformity does not exist with regard to the indication criteria of seminal vesicle biopsies (SVBs). Our objective is to analyse the protocol of SVBs at Morales Meseguer Hospital and conduct an exhaustive review of the literature in this field. METHODS AND MATERIALS: SVBs were performed in patients who were amenable to a curative treatment and who showed at least one of the following indication criteria: prostate-specific antigen greater than or equal to 15 ng/ml, a prostate cancer nodule in the base of the prostate, or ultrasound abnormalities suggestive of vesicular involvement. SVBs were performed in 70 patients. RESULTS: These results revealed a rate of SVI of 15.7 and 25.58 % among all patients and patients diagnosed with prostate cancer, respectively. All biopsied patients who tested positive for the three indication criteria had T3b prostate cancer. Patients with a prostate cancer that altered the base of the prostate according to either digital rectal examination or ultrasound showed a T3b rate of 53.8 %. CONCLUSIONS: SVBs should be considered a complementary procedure for prostate cancer staging because provide important information and it is easy, inexpensive and has few complications.
