Reconstrucción poscirugía de Hartmann / Stoma reversal after the Hartmann's procedure

RESUMEN Antecedentes: la reconstrucciónn del tránsito intestinal luego de una operación de Hartmann es un procedimiento habitualmente complejo y con alta morbilidad. Objetivo: analizar la tasa de reconstrucción después de la cirugía de Hartmann y resultados posoperatorios en nuestra experiencia. Material y métodos: análisis retrospectivo de pacientes a los que se les practicó la reconstrucción del tránsito intestinal posterior a una cirugía de Hartmann en un período 16 años. Revisamos la bibliografía y nuestra base de datos. Luego traspasamos la información disponible a una grilla de datos construida con variables habitualmente analizadas en la literatura. Finalmente, analizamos los resultados mediante medidas básicas de tendencia central. Resultados: en 16 años realizamos 92 operaciones de Hartmann, de las cuales 69 (75%) llegaron a la reconstrucción. Edad promedio: 58 años. El 52% de los pacientes fueron hombres. La operación de Hartmann fue de urgencia en el 48% y 58% resultaron malignas. Tiempo transcurrido hasta la reconstrucción: en promedio, 9 meses, y el 90% (N 62) de los casos se realizó por vía laparoscópica. Morbilidad general 38% y ajustada a los grados III y IV de Clavien-Dindo fue 11,5%. No hubo mortalidad. Conclusión: los resultados obtenidos son semejantes a los publicados y nuestra experiencia nos motiva a continuar eligiendo el abordaje laparoscópico.

ABSTRACT Background: Background: Stoma reversal after Hartman's operation is usually a complex procedure and is associated high morbidity. Objective: To analyze the rate of reversal after the Hartmann's procedure and the postoperative outcomes in our experience. Material and methods: We conducted a retrospective analysis of patients undergoing reversal after the Hartmann's procedure over a 16-year period with review of the literature and of our database and transferred the available information to a data grid constructed with variables commonly analyzed in the literature. Finally, we analyzed the results using basic measures of central tendency. Results: Over a 16-year period, we performed 92 Hartmann's operations; 69 (75%) reached the reversal stage. Mean age was 58 years and 52% were men. Forty-eight percent of the Hartmann's procedures were emergency surgeries and 58% were due to cancer. Mean time to reversal was 9 months and 90% (n = 62) were laparoscopic procedures. Overall morbidity and adjusted for complications grade III and IV of the Clavien-Dindo classification were 38% and 11.5%, respectively. None of the patients died. Conclusion: The results obtained are similar to those published and our experience motivates us to continue choosing the laparoscopic approach.

Trastorno grave del medio interno por fístula enterovesical, a propósito de un caso clínico / Severe metabolic disorder associated with an enterovesical fistula: report of one case

Enterovesical fistula (EVF) is a fistulous communication between the intestine and the bladder. It is uncommon and its classic clinical manifestations are the presence of pneumaturia, fecaluria, suprapubic pain and recurrent urinary infections. Surgical repair of EVF leads to rapid correction of both diarrhea and metabolic abnormalities. We report a 73-year-old diabetic woman with a neurogenic bladder secondary to a spine meningioma. She presented with diarrhea, vomiting, impaired consciousness and metabolic acidosis. She developed hypernatremia, hypokalemia, hypocalcemia, and hypophosphatemia, which were successfully corrected.

Fístula colovesical de origen diverticular. Resolución laparoscópica con nuevo recurso técnico / Diverticular colovesical fistulae. Laparoscopic tip

Introducción: La enfermedad diverticular de colon es una patología de alta prevalencia en nuestro medio. Su presentación inicial como fístulas no complicadas no es frecuente sin antecedentes de episodios de diverticulitis previa. Objetivos: Presentar detalles técnicos de la cirugía de resección y tratamiento laparoscópico de una fistula colovesical de origen diverticular. Materiales y métodos: Se presenta el caso de un paciente varón de 63 años con dolor en hipogastrio sin alteraciones evacuatorias ni cirugías previas. Sin antecedentes de diverticulitis. Se realizó ecografía abdominal y tomografía computada donde se constata aire en vejiga. El urocultivo es positivo para escherichia coli y el colon por enema detecta pequeño trayecto fistuloso entre colon sigmoides y vejiga. Se decide resección laparoscópica. Resultados: Se realizó una colectomía sigmoidea laparoscópica con identificación de trayecto fistuloso a la vejiga que se aisló y seccionó entre clips de polímero. Se completó con anastomosis primara colorrectal y sondaje vesical prolongado que se retiró a los 15 días. Los parámetros postoperatorios fueron favorables con egreso a las 72 hs. Conclusión: La fístula colovesical es una complicación de la enfermedad diverticular de colon aunque es rara su debut como forma de presentación sin episodios de diverticulitis previa. Se destaca su identificación como trayecto único y no hemos encontrado mención al respecto en la bibliografía. Su resolución de ligadura entre clips es una opción terapéutica efectiva y rápida para su resolución definitiva. El abordaje laparoscópico electivo es de elección y su tratamiento mediante el procedimiento propuesto resultó efectivo y seguro.

Background: Diverticular disease is a high prevalent colonic pathology. Initial presentation as complicated disease includes fistulas, perforation and bleeding. Objetive: To present technical surgical aspects of surgical treatment of laporoscopic resection of colovesical fistula after diverticular disease. Methods: A 63 years old patient presented with low abdominal pain and no transit symptoms. There was no previous surgery and diverticulitis episode. Abdominal ultrasound and CT scan showed air in the bladder. Urine culture was positive to Escherichia coli. Colonic barium x-rays showed a colovesical fistula. Laparoscopic resection was decided as treatment of choice. Results: Laparoscopic sigmoid colectomy, aisolation of fistula tract and posterior clips ligation and section. Primary mecanic anastomosis and 15 days vesical catheter completed the treatment. Postoperative evolution was satisfactory. Conclusions: Colovesical fistula is a frequent complication of complicated diverticular disease, however its debut without previous episodes is rare. The colonic fistula presented as unique tract is unfrequent. Resolution by polimer clips and section associated with colonic resection by laparoscopic is a good option to avoid bladder sutures. This procedure resulted safe and effective.

Persistencia simultánea del conducto uraco y onfalomesentérico en un paciente adulto, reporte de caso / Simultaneous persistence of the urachus and vitelline ducts in an adult patient, case report / Persistência simultânea de úraco e do ducto onfalomesentérico em um paciente adulto: relato de caso

Introducción. La patología umbilical es un tema frecuente en el ámbito pediátrico, la presentación clínica de una fístula umbilical hace pensar en dos patologías mencionadas en la literatura de manera independiente; la primera es la persistencia del conducto onfalomesentérico y la segunda es la persistencia del remanente del uraco producto del fracaso en el cierre de las estructuras embrionarias. Su presencia en adultos es infrecuente y no existen datos estadísticos acerca de su presentación conjunta en población pediátrica o adulta, solo algunos pocos reportes de caso. El diagnóstico se basa principalmente en la sospecha clínica, depende en gran manera del examen físico al evidenciar secreción a través del ombligo al realizar esfuerzos o maniobras de Valsalva. Objetivo. Mostrar un caso infrecuente de la presentación simultánea del conducto de uraco y onfalomesentérico en un paciente adulto. Reporte de caso. Paciente femenina de 24 años de edad con antecedentes de infecciones urinarias y celulitis periumbilicales a repetición. Se sospecha un conducto persistente onfalomesentérico por lo que es sometida a un procedimiento quirúrgico en el que se encontró incidentalmente la persistencia simultánea del conducto onfalomesentérico y persistencia del uraco. Discusión. La persistencia del conducto onfalomesentérico o la persistencia del uraco de forma individual es poco frecuente en adultos, y es aún más raro la persistencia simultánea de ambos conductos; la presencia simultánea de ambos conductos es reportada principalmente en menores de dos años. Conclusiones. La persistencia de estos conductos es rara en adultos y representa un reto diagnóstico para el clínico.

Introduction. Umbilical pathology is a common topic in the pediatric sphere. The clinical presentation of an umbilical fistula leads to the consideration of two pathologies independently reported in literature. The first is a persistent vitelline duct and the second is a persistent urachal remnant as a result of the embryonic structures' failure to close. They are uncommon in adults and there are no statistical data about their presentation together in the pediatric or adult population, only very few case reports. The diagnosis is mainly based on clinical suspicion. It largely depends on a physical examination noting secretion through the navel when straining or performing Valsalva maneuvers. Objective. Show an uncommon case of the simultaneous presentation of the urachus and vitelline ducts in an adult patient. Case report. Female patient aged 24 years with a background of repeated urinary tract infections and periumbilical cellulitis. A persistent vitelline duct is suspected. Therefore, the patient is subject to a surgical procedure in which the simultaneous persistence of the vitelline duct and the urachus was found incidentally. Discussion. The persistence of the vitelline duct or the persistence of the urachus individually is uncommon in adults, and the simultaneous persistence of both ducts is even rarer. The simultaneous presence of both ducts is reported mainly in infants aged under two years. Conclusions. The persistence of these ducts is rare in adults and poses a diagnostic challenge for clinicians.

Introdução. A patologia umbilical é um tópico frequente no cenário pediátrico; a apresentação clínica de uma fístula umbilical faz pensar em duas patologias mencionadas na literatura de forma independente; a primeira é a persistência do ducto onfalomesentérico e a segunda é a persistência do úraco como resultado da falha no fechamento das estruturas embrionárias. É pouco frequente sua presença em adultos e não há dados estatísticos sobre sua apresentação conjunta em população pediátrica nem adulta, apenas alguns poucos relatos de caso. O diagnóstico baseia-se principalmente na suspeita clínica, dependendo em grande parte do exame físico ao evidenciar uma secreção pelo umbigo quando realizar esforço ou manobra de Valsalva. Objetivo. Mostrar um caso infrequente de apresentação simultânea do úraco e ducto onfalomesentérico em um paciente adulto. Relato de caso. Paciente do sexo feminino, 24 anos, com histórico de infecções urinárias e celulite periumbilical recorrentes. Suspeita-se de um ducto onfalomesentérico persistente, portanto ela é submetida a um procedimento cirúrgico no qual encontrou-se a persistência do ducto onfalomesentérico e a persistência de úraco simultaneamente. Discussão. A persistência do ducto onfalomesentérico e a persistência de úraco individualmente é rara em adultos, e a persistência simultânea de ambos os ductos é ainda mais rara; esta presença simultânea é relatada principalmente em crianças menores de dois anos de idade. Conclusão. A persistência desses ductos é rara em adultos e representa um desafio diagnóstico para o profissional de saúde clínico.

Live fetus inside the urinary bladder: a case report / Feto vivo dentro da bexiga urinária: relato de caso

ABSTRACT Vesicouterine fistula is a rare condition. Its incidence, however, has been increasing due to the higher incidence of cesarean sections. The presence of a live fetus inside the bladder who passed through a vesicouterine fistula is an extremely rare situation. We report a case of woman who underwent two previous cesarean sections, was referred to a hospital due to mild pelvic pain and genital bleeding. At the moment, physical examination was normal. Ultrasound scan revealed a gestational sac inserted into the anterior wall of the uterus, with a living fetus of approximately 13 weeks, with active body movement and normal heart rate inside it. The fetal abdomen, around the waist, was stuck at the opening of a vesicouterine fistula, so that the fetal head and trunk were entirely into the bladder cavity, while lower limbs remained at the uterine cavity. Laparotomy was performed, the fistulous tract was excised, the fetus (without heart beating) was removed on opening the bladder, and the uterine cavity was emptied. The defects in the bladder and uterus were repaired. The postoperative period was uneventful. A live fetus inside the urinary bladder is a rare condition the continuation of pregnancy is unlikely and the vesicouterine correction can be made by the time of surgical intervention.

RESUMO A fístula vesicouterina é uma condição rara. Sua incidência, no entanto, vem aumentando, devido à maior incidência de cesáreas. A presença de feto vivo dentro da bexiga por meio de uma fístula vesicouterina constutui situação extremamente rara. Relatamos o caso de uma mulher com duas cesarianas anteriores encaminhada para o hospital devido à dor pélvica leve e sangramento genital. Na hospitalização, o exame físico estava normal. A ultrassonografia revelou saco gestacional inserido na parede anterior do útero com feto vivo de aproximadamente 13 semanas, com movimento corporal ativo e frequência cardíaca normal. O abdômen fetal, ao redor da cintura, estava preso na abertura de uma fístula vesicouterina de modo que a cabeça e o tronco fetais estavam totalmente dentro da cavidade da bexiga, enquanto os membros inferiores permaneciam na cavidade uterina. A laparotomia foi realizada, o trajeto fistuloso foi excisado, o feto (que estava sem batimento cardíaco) foi removido ao abrir a bexiga, sendo a cavidade uterina esvaziada. Além disso, foram reparados os defeitos na bexiga e no útero. O pós-operatório transcorreu sem intercorrências. Feto vivo dentro da bexiga é uma condição rara, e a continuidade da gravidez é improvável, sendo que a correção vesicouterina pode ser feita no momento da intervenção cirúrgica.

Vesicouterine fistula (Youssef syndrome): case report and literature review / Fístula vesico-uterina (síndrome de Youssef): descrição de caso e revisão da literatura

Abstract Objective To describe a case of vesicouterine fistula and to review the literature related to this condition. Methods For the review, we accessed the MEDLINE, BIREME and LILACS databases; the references of the searched articles were also reviewed. Results A 38-year-old woman, in the 1st day after her 3rd cesarean, presented heavy hematuria, which was considered secondary to a difficult dissection of the bladder. A total of 6 months after delivery, she failed to resume her regular menstrual cycles and presented cyclic menouria and amenorrhea. At this time, she had two episodes of urethral obstruction by blood clots. She remained without a correct diagnosis until about two years postdelivery, when a vesicouterine fistula was confirmed through cystoscopy. A surgical correction through open abdominal route, coupled with hysterectomy, was performed. After the surgery, the symptoms disappeared. The review showed a tendency of change in the relative frequency of the different types of genitourinary fistulae. Vesicovaginal fistulae, usually caused by inadequate care during labor, are becoming less frequent than those secondary tomedical procedures, such as vesicouterine fistulae. The most common cause of this latter kind of fistula is cesarean section, especially repeated cesarean sections. The diagnosis is confirmed through one or more imaging exams, or through cystoscopy. The most common treatment is surgical, and the routes are: open abdominal, laparoscopic, vaginal or robotic. There are some reports of success with the conservative treatment. Conclusion Vesicouterine fistulae are becoming more common because of the increase in the performance of cesarean sections, and the condition must be considered a possible complication thereof.

Resumo Objetivo Apresentar um caso de fístula vesico-uterina e realizar revisão da literatura sobre esta condição. Métodos Revisão realizada consultando-se as bases MEDLINE, BIREME e LILACS, além das referências dos artigos consultados. Resultados Uma mulher de 38 anos, após sua terceira cesárea, no puerpério imediato, apresentou hematúria importante, que foi atribuída a uma dificuldade na dissecção da bexiga durante o procedimento. Seis meses pós-parto, emvez de retomar os ciclos menstruais regulares, apresentou menúria cíclica e amenorreia (síndrome de Youssef). A paciente chegou a apresentar obstrução uretral por coágulos, e permaneceu sem diagnóstico correto até cerca de anos pós-parto, quando este foi feito por cistoscopia. Ela foi então submetida a correção cirúrgica por via abdominal, associada a uma histerectomia, com desaparecimento dos sintomas. A revisão mostrou que tem havido mudança na frequência dos vários tipos de fístulas urogenitais. As fístulas vesicovaginais, normalmente secundárias à má assistência durante o parto, têm sido mais raras, enquanto aquelas secundárias a procedimentos médicos, como as vesicouterinas, têm sido mais frequentes. A causa mais comum deste tipo de fístula é a cesárea, especialmente a de repetição. A apresentação pode ser de amenorreia e menúria e/ou perda urinária. O diagnóstico é feito por um ou maismétodos de imagem ou cistoscopia. O tratamento mais comum é cirúrgico, por via abdominal aberta, laparoscópica, transvaginal ou robótica. Existem relatos de cura com tratamento conservador. Conclusão As fístulas vesicouterinas têm sido mais comuns devido ao aumento da proporção de cesáreas. Deve-se ter em mente a possibilidade deste diagnóstico e considerá-las uma das possíveis complicações da cesárea.

Transanal Minimally Invasive Surgery (TAMIS) to Treat Vesicorectal Fistula: A New Approach

ABSTRACT Purpose: Vesicorectal fistula is one of the most devastating postoperative complications after radical prostatectomy. Definitive treatment is difficult due to morbidity and recurrence. Despite many options, there is not an unanimous accepted approach. This article aimed to report a new minimally invasive approach as an option to reconstructive surgery. Materials and Methods: We report on Transanal Minimally Invasive Surgery (TAMIS) with miniLap devices for instrumentation in a 65 year old patient presenting with vesicorectal fistula after radical prostatectomy. We used Alexis® device for transanal access and 3, 5 and 11 mm triangulated ports for the procedure. The surgical steps were as follows: cystoscopy and implant of guide wire through fistula; patient at jack-knife position; transanal access; Identification of the fistula; dissection; vesical wall closure; injection of fibrin glue in defect; rectal wall closure. Results: The operative time was 240 minutes, with 120 minutes for reconstruction. No perioperative complications or conversion were observed. Hospital stay was two days and catheters were removed at four weeks. No recurrence was observed. Conclusions: This approach has low morbidity and is feasible. The main difficulties consisted in maintaining luminal dilation, instrumental manipulation and suturing.

Características e diagnóstico diferencial das doenças inflamatórias intestinais / Characteristics and differential diagnosis of inflammatory bowel diseases

As doenças inflamatórias intestinais (DIIs) compreendem, principalmente, a doença de Crohn (DC) e a retocolite ulcerativa (RU), ambas idiopáticas, porém relacionadas a uma resposta imunológica anormal à microbiota bacteriana da luz intestinal. Na RU a inflamação é difusa, restrita à mucosa e inespecífica, com comprometimento contínuo da parede, principalmente do reto, enquanto na DC as lesões são descontínuas, podem comprometer todas as camadas da parede e afetar qualquer parte do trato gastrointestinal. O quadro clínico é comum e compreende diarreia, febre e dores abdominais, podendo cursar também com manifestações extraintestinais. O diagnóstico é feito através dos dados clínicos, achados radiológicos e histológicos, sem haver, no entanto, nenhuma característica que isoladamente feche o diagnóstico de DII específica.

Inflammatory bowel diseases (IBDs) comprise mainly Crohn?s disease (CD) and ulcerative colitis (UC), both are idiopathic but believed to be related to an abnormal immune response to bacterial microbiota in the intestinal lumen. In RU diffuse inflammation is restricted to the mucosa and is nonspecific, with continued commitment that stars at rectum?s wall. In DC, the injuries are discontinuous, involve all layers of the intestinal wall and can affect any part of the gastrointestinal tract. The clinical picture of both is diarrhea, fever, abdominal pain, and may present with extraintestinal manifestations. The diagnosis is made by the junction of clinical, radiological and histological findings, without having, however, a feature alone that leads to a diagnosis of a specific IBD.

Epididymitis in Patients with Anorectal Malformations: A Cause for Urologic Concern

Introduction Epididymitis in patients with anorectal malformation (ARM) represents a unique problem because unlike the general population, an underlying urinary tract problem is frequently identified. We review our experience with epididymitis in ARM population with an emphasis on examining urologic outcomes. Materials and Methods We performed a retrospective review of male patients with ARM cared for from 1980 to 2010. Clinical and pathologic variables recorded included age at presentation, recurrence, associated urologic anomalies, incidence of ureteral fusion with mesonephric ductal structures, glomerular filtration rate and urodynamic parameters. Results Twenty-six patients were identified with documented episodes of epididymitis. Renal injury was noted in five patients (19%), all of whom were diagnosed with neurogenic bladder (NGB) several years after anorectoplasty. NGB was found in ten patients (38%) in our series. Ectopic insertion of ureter into a mesonephric ductal structure was discovered in five patients (19%). Twelve patients (46%) had recurrent episodes of epididymitis, with seven of these patients (58%) being diagnosed with NGB. Two patients in the pubertal group presented with a history of epididymitis and complained of ejaculatory pain. Conclusion Epididymitis in a patient with ARM warrants a comprehensive urologic investigation, particularly in recurrent episodes. Attempts at surgical intervention (e.g. vasectomy) should be avoided until functional assessment of the urinary tract has occurred. Failure to recognize this association may lead to potentially avoidable complications and morbidity. Long term urological follow up of these patients is warranted to identify at risk patients and minimize renal deterioration .

Vesicoenteric Fistula due to Bladder Squamous Cell Carcinoma

Vesicoenteric fistula is a rare complication of bladder squamous cell carcinoma. We report the case of a 70-year-old male who complained of painless, total gross hematuria. Abdominopelvic computed tomography (CT) revealed an approximately 2.7-cm lobulated and contoured enhancing mass in the bladder dome. We performed partial cystectomy of the bladder dome after transurethral resection of the bladder. The biopsy result was bladder squamous cell carcinoma, with infiltrating serosa histopathologically, but the resection margin was free. Postoperatively, follow-up CT was done after 3 months. Follow-up CT revealed an approximately 4.7-cmx4.0-cm lobulated, contoured, and heterogeneous mass in the bladder dome. A vesicoenteric fistula was visible by cystography. Here we report this case of a vesicoenteric fistula due to bladder squamous cell carcinoma.

Infecção do trato urinário de repetição por fístula enterovesical secundária a doença diverticular do cólon: um relato de caso / Recurrent urinary tract infection due to enterovesical fistula secondary to colon diverticular disease: a case report

INTRODUÇÃO: As fístulas enterovesicais (FEV) são comunicações patológicas entre a bexiga e as alças intestinais pélvicas. Trata-se de uma rara complicação decorrente de doenças inflamatórias e neoplásicas da pelve, além de casos resultantes de iatrogenia, e associa-se a altos índices de morbimortalidade. RELATO DO CASO: Trata-se de um paciente de 61 anos com um quadro de dor e distensão abdominal, vômitos, parada de eliminação de fezes e flatos. APP: Hipertenso, diabético, com antecedentes de disfunção vesical e infecções do trato urinário de repetição (ITUr) nos últimos três anos. Por meio da realização de ressonância magnética de abdômen e pelve, diagnosticou-se FEV associada à doença diverticular (DDC) do sigmoide. A conduta estabelecida consistiu em colectomia parcial com rebaixamento de colo e cistectomia parcial com colocação cirúrgica de cateter duplo jota à esquerda. DISCUSSÃO: Embora consista de afecção primária do trato digestivo, normalmente o paciente com DDC associada a FEV procura atendimento médico em decorrência de queixas do trato urinário. Nesse caso, a demora no diagnóstico fez com que a queixa principal fosse do trato digestivo e com antecedentes de queixas urinárias. CONCLUSÃO: Apesar de pouco frequente, a ocorrência de ITUr associada à DDC deve ser sempre considerada no diagnóstico diferencial das ITUr pela alta morbimortalidade.

INTRODUCTION: Enterovesical fistula are pathological connections between the bladder and pelvic intestinal segments. It consists of a rare complication of neoplastic and inflammatory pelvic disorders, in addition to iatrogenic or traumatic injuries, and correlates with both high morbidity and mortality indexes. CASE REPORT: Male patient, 61 years old, admitted at the hospital clinics featuring abdominal pain and distension, vomiting and fecal retention. Patient's pathological precedents include high blood pressure, diabetes mellitus, vesical dysfunction and recurrent urinary tract infection on the past three years. Magnetic resonance imaging of abdomen and pelvis revealed enterovesical fistula in association with colon diverticular disease of the sigmoid. Management of choice consisted of partial colectomy with bowel lowering and partial cystectomy with surgical double-J stent insertion. DISCUSSION: Although consisting of a gastrointestinal primary affection, patients with enterovesical fistula usually search for medical help charging urinary tract features. In this particular case, our patient was admitted with gastrointestinal symptoms, reasoned by diagnostic delay, as the patient had already attended at multiple centers with urinary symptoms. CONCLUSION: Despite being an unusual affection, recurrent urinary tract infection associated with colon diverticular disease must always be considered at differential diagnosis of recurrent urinary tract infection as it concurs with high morbidity and mortality.

Magnetic resonance imaging to detect vesico-symphyseal fistula following robotic prostatectomy

Pubic complications following radical prostatectomy are rare. Osteitis pubis typically presents with symptoms related to irritation of the pubic rami including pain with ambulation and adduction of the leg. A 60-year-old male with prostatic adenocarcinoma underwent uneventful robotic assisted laparoscopic prostatectomy. The patient noted the onset of severe pubic pain exacerbated by ambulation approximately one month post-surgery. An abdominal/pelvic CT scan was negative for acute pathology. Due to continued discomfort, a multiplanar MRI of the pelvis was performed with and without intravenous contrast material (20 ml Omniscan). The MRI demonstrated irregularity of the bladder base and proximal urethra with a fistulous tract extending anteriorly in direct communication with the pubic symphysis joint space. Vague periarticular marrow edema-like signal and enhancement at the pubic symphysis was thought to represent osteitis pubis. The patient's symptoms resolved after one month of urethral catheter drainage, intravenous antibiotics, and anti-inflammatory therapy.

Prune belly syndrome with urethral hypoplasia and vesico-cutaneous fistula: a case report and review of literature

Association between Prune belly syndrome [PBS] and urethral hypoplasia is an unusual condition. It is usually fatal unless there is a communication between the fetal bladder and the amniotic sac. We report a case of PBS with urethral hypoplasia and congenital vesico-cutaneous fistula in a male neonate. Patient underwent cutaneous vesicostomy and was discharged for close follow up of his renal function and for future reconstruction

Fístula colovesical secundaria a enfermedad diverticular: cirugía laparoscópica electiva / Colovesical fistula: laparoscopic surgery

Aim: Colovesical fistula is a severe complication associated to neoplastic or inflammatory colon disease. Most common procedure is open surgery. We report a case of colovesical fistula secondary to diverticular disease treated with a laparoscopic approach. Methods: A 64-year-old man was seen with a known colonic diverticular disease, type 2 diabetes mellitus and recurrent urinary tract infection. He complained of lower abdominal pain, dysuria, and pneumaturia. A CT scan revealed a sigmoid diverticular perforation into the bladder (colovesical fistula). A left hemicolectomy with partial cystectomy was performed by laparoscopy means. Results: There was no morbidity related to the surgical procedure, and the final pathology confirmed a colonic diverticular disease with bladder compromise. The patient is asymptomatic at 24 months of follow up. Conclusion: The laparoscopic approach is a feasible alternative for the treatment of colovesical fistula with low morbidity.

Objetivos: La fístula colovesical es una complicación relacionada con procesos inflamatorios y neoplá-sicos del colon. El manejo tradicional de esta patología es quirúrgico bajo técnica abierta. Presentamos un caso de fístula colovesical secundaria a enfermedad diverticular con tratamiento quirúrgico laparoscópico. Materiales y Métodos: Paciente masculino de 64 años de edad, portador de enfermedad diverticular de larga data con antecedente de diabetes mellitus tipo 2 e infecciones urinarias a repetición, quien consulta por presentar dolor en hipogastrio, disuria y neumaturia. Se realiza tomografía computada que revela perforación diverticular de colon sigmoides a vejiga (fístula colovesical). Se realizó hemicolectomía izquierda más cistectomía parcial, con resección del trayecto fistuloso, y cierre vesical y anastomosis colónica laparoscópica. Resultados: No hubo complicaciones intra ni postoperatorias. El estudio anatomopatológico de la pieza operatoria demostró enfermedad diverticular. El paciente se encuentra asintomático a los 24 meses de seguimiento. Conclusión: El abordaje laparoscópico es una alternativa factible para el tratamiento de fístula colovesical, con baja morbilidad.

Hematuria fatal por fístula ilíaco-vesical, reporte de caso / Lethal hematuria du to ilio-vesical fistula. Case report

Las fístulas ilíaco-vesicales son una rara complicación de los aneurismas de la aorta abdominal. Se presenta el caso de un paciente de 76 años con aneurisma roto de arteria ilíaca contenido en vejiga, que se manifestó por dolor abdominal y hematuria, y en quien se sospechó por tomografía una fístula ilíaco-vesical, la cual se confirmó durante la cirugía. El paciente falleció a los 20 días del procedimiento, por shock mixto séptico.

Iliocovesical fistulas are infrequent complications of abdominal aortic aneurysms (AAA). We report the case of a 76 year-old male with a contained ruptured aneurysm of the iliac to the urinary bladder. Complaints on presentation were abdominal pain and hematuria; suspected iliacovesical fistula was reported on a computed tomography (CT) scan, which was confirmed during laparotomy. The patient died 20 days after the procedure due to mixed distributive septic shock.

Bladder Reconstruction Using Bovine Pericardium in a Case of Enterovesical Fistula

The use of graft materials in bladder mucosa has been examined in animal models, but debate exists over which materials are effective. Intestine has been used as a substitute in augmentation cystoplasty for patients with neuropathic bladder, but serious adverse effects of the operation have occurred in some instances. We report a case of a successful repair of an enterovesical fistula by use of bovine pericardium. The patient has remained well for 2.5 years. We suggest that bovine pericardium may be a suitable option as a bladder substitute.

Vesico-Acetabular Fistula and Urolithiasis in the Hip Joint Cavity due to Persistent Bladder Entrapment after Acetabular Fracture

We report a rare case of vesico-acetabular fistula due to an improperly treated pelvic fracture with urinary stone formation in the joint cavity. This complication was related to an unrecognized mechanism of bladder wall entrapment in the acetabular floor defect during weight bearing. This situation led to several mistreatment decisions in our case and should be always considered by urologists dealing with patients after major pelvic trauma. In this case report, we analyze the publications related to this problem, discuss the main mechanisms of bladder wall damage after acetabular fracture, and propose tips for diagnosis and treatment.

Fístula colovesical de origen diverticular / Results of surgical treatment of colovesical fistulas of diverticular origin

Background: The main causes of colovesical fistulas are diverticular disease of the colon and colon carcinoma. Aim: To analyze the results of the surgical treatment of colovesical fistulas of diverticular origin. Material and Methods: Retrospective analysis of all patients operated for a colovesical fistula of diverticular origin. Results: From 141 patients subjected to a colon excision for diverticular disease, 18 had a colovesical fistula. The latter, compared to patients without fistulas were male in a higher proportion, were younger and had more concomitant diseases. Pneumaturia was reported in 83 percent and urine fecal soiling in 56 percent. In two thirds of patients, the fistula appeared in the absence of a diverticular crisis. Abdominal CAT sean demonstrated the fistula in 80 percent of cases. It was complemented with barium enema and cystoscopy. Excision with immediate anastomosis was the surgical procedure used in 94 percent of patients, without sequelae or relapse, after a mean follow up of 74 months. No patient died during the procedure or required a new intervention. Conclusions: Colovesical fistulas are most common in young men with associated diseases and their treatment of choice, with good long-term results, is primary excision.

Antecedentes: El objetivo de este estudio es analizar los resultados del tratamiento quirúrgico de la Fístula Coló Vesical (FCV) de origen diverticular, los que se comparan con la enfermedad diverticular no fistulizada. Pacientes y Método: Análisis retrospectivo de todos los pacientes intervenidos por una FCV de origen diverticular en forma consecutiva. Resultados: De un total de 141 pacientes resecados por una enfermedad diverticular del colon sigmoides, la indicación quirúrgica en 27 (19,3 por ciento) fue la presencia de una fístula, de las cuales 18 corresponden a una FCV. El grupo con FCV tiene predominio de hombres (p = 0,0001), más joven (p = 0,027) y con mayor incidencia de enfermedades asociadas (p = 0,0001). La neumaturia se presentó en el 83 por ciento y la fecaluria en el 56 por ciento. En dos tercios de los casos la FCV se estableció en ausencia de una crisis diverticular previa. El estudio más relevante para demostrar la presencia de una FCV fue la tomografía computada (80 por ciento), que se complementa con el enema balitado y la cistoscopia. La resección con anastomosis inmediata, más simple sutura de la vejiga fue el procedimiento empleado en el 94 por ciento de los pacientes, sin secuelas ni casos de recidiva, con un seguimiento global promedio de 74,2 meses (extremos 12-158). No hubo reoperaciones ni mortalidad operatoria. Conclusiones: la FCV de origen diverticular es una condición patológica poco frecuente que afecta a pacientes varones en la séptima década de la vida, con múltiples enfermedades asociadas y que frecuentemente se instala en forma silenciosa. La resección primaria es el tratamiento de elección con buenos resultados a largo plazo.
