Fístula sigmoido-glútea como complicación infrecuente de la enfermedad diverticular / Sigmoid-gluteal fistula as a rare complication of diverticular disease

Las fistulas colo-cutáneas de origen diverticular son poco frecuentes, máxime en ausencia de cirugía o drenaje percutáneo previos. Presentamos una mujer de 90 años con una sigmoitis complicada con una colección abdominal perforada hacia el retroperitoneo y la región glútea. (AU)

Colocutaneous fistulas of diverticular origin are rare, especially in the absence of prior surgery or percutaneous drainage. We report the case of a 90-year-old woman with sigmoitis and a perforated abdominal collection in the retroperitoneum and gluteal region. (AU)

Fístula gastrocólica secundaria a cáncer de colon / Gastrocolic fistula secondary to colon cáncer / Fístula gastrocólica secundária a câncer de cólon

La fístula gastrocólica descrita en 1755 por Albrecht von Haller, se define como la comunicación anormal entre el colon generalmente transverso y estómago en su curvatura mayor. Se conocen distintas etiologías, siendo un hallazgo poco frecuente con escasos reportes en la literatura. Se presenta el caso de una paciente de 85 años con historia de anemia y adelgazamiento que consulta por cuadro de vómitos fecaloideos, sin alteraciones de tránsito digestivo bajo, sin dolor ni distensión abdominal con ruidos hidroaéreos normales y sonda nasogástrica con contenido fecaloideo. La Tomografía (fig. 1) confirma una lesión de probable etiología maligna del ángulo esplénico del colon fistulizado a estómago por lo que se decide la realización de una colectomía sectorial con anastomosis primaria y gastrectomía subtotal, evolucionando favorablemente con un alta a los 6 días. La anatomía patológica informa adenocarcinoma de colon moderadamente diferenciado con compromiso gástrico.

Absceso del psoas ilíaco secundario a un tumor de colon izquierdo fistulizado al retroperitoneo: caso clínico y análisis de la literatura / Iliopsoas abscess resulting from penetrating left colon cancer to the retroperitoneum: case report and literature review / Abscesso do iliopsoas secundário a tumor de cólon esquerdo fistulizado para o retroperitônio: caso clínico e análise da literatura

Los abscesos del psoas ilíaco secundarios a un tumor de colon fistulizado son excepcionales y potencialmente graves. La mayoría son adenocarcinomas de tipo mucinoso. Su tratamiento es complejo ya que, para lograr una resección oncológica pretendidamente curativa, es necesario realizar una resección ampliada con mayor morbimortalidad. Presentamos el caso de una paciente con un adenocarcinoma mucinoso de colon izquierdo fistulizado al músculo ilíaco y la pared anterolateral del abdomen en la que se realizó una resección multivisceral que incluyó el colon izquierdo, el músculo y la cresta ilíaca y parte de la pared anterolateral del abdomen.

Iliopsoas abscess secondary to perforation of colon cancer is an extremely rare and potentially life-threatening condition. Most tumors are mucinous adenocarcinomas. Its treatment its complex, as most patients need radical extended resections to achieve good oncological results, which are in turn, graved with higher morbidity and mortality. We present the case of a patient with a left colon mucinous adenocarcinoma penetrating to the iliopsoas muscle and the anterolateral abdominal wall that required a multivisceral resection including left colon, iliac muscle and crest and part of the anterolateral abdominal wall.

Abscessos do iliopsoas secundários a um tumor de cólon fistulizado são raros e potencialmente graves. A maioria são adenocarcinomas do tipo mucinoso. Seu tratamento é complexo, pois, para se obter uma ressecção oncológica supostamente curativa, é necessário realizar uma ressecção ampliada com maior morbimortalidade. Apresentamos o caso de um paciente com adenocarcinoma mucinoso de cólon esquerdo fistulizado para o músculo ilíaco e parede ântero-lateral do abdome no qual foi realizada ressecção multivisceral que incluiu cólon esquerdo, músculo e crista ilíaca e parte do a parede anterolateral do abdome.

Fístula sigmoido-cervical secundaria a una enfermedad diverticular complicada / Sigmoido-cervical fistula due to diverticular disease

Resumen Introducción: Las fístulas secundarias a una enfermedad diverticular complicada son una indicación formal de cirugía electiva en el 4 a 23% de los casos. Caso Clínico: Se presenta el caso de una mujer de 52 años con antecedentes de una histerectomía subtotal por miomatosis uterina que consulta por cuadro de dolor abdominal en hipogastrio acompañado de fiebre de 4 días de evolución. La tomografía computada (TC) de abdomen y pelvis describe una diverticulitis complicada con absceso peridiverticular. Tratada con antibióticos con buena respuesta clínica consulta a los 3 meses en nuestro servicio por pérdida de material fecal por vagina. Nueva TC confirma la presencia de una colección perisigmoidea y engrosamiento de la pared vesical. La colonoscopía informa una estenosis franqueable a nivel de sigmoides y se constata salida de gases por vagina. La corrección quirúrgica electiva incluyó una sigmoidectomía abierta con traquelectomía en block, cierre de la cúpula vaginal y anastomosis colorrectal mecánica, con buena evolución posoperatoria, sin recidiva a los 12 meses de seguimiento. La fístula sigmoido-cervical es una complicación rarísima de la enfermedad diverticular complicada que puede ocurrir en pacientes sometidas a una histerectomía subtotal previa. Aunque el diagnóstico de la fístula es clínico, la colonoscopía y la TC permiten descartar otras etiologías. La resección radical del segmento afectado es el tratamiento estándar en pacientes aptos.

Introduction: Diverticular disease is complicated by fistulas in 4% to 23% of patients. Case Report: A woman 52 years-old previously operated on with parcial histerectomy was successfully treated with antibiotics due to diverticulitis complicated with an abscess. Three months later the patient presented with vaginal discharge of faeces. Computed tomography showed wall thickening of sigmoid colon and vesical wall. Colonoscopy exclude cancer and confirmed the exit of gas through vagina. En-bloc resection of the sigmoid colon with traquelectomy with primary anastomosis was performed. The postoperative course was good without recurrence after 12 months of follow up. Sigmoido-cervical fistula is a very rare benign fistula due to diverticular disease. Diagnosis is basically clinic, but tomography and colonoscopy are important to exclude other causes of fistulas. Radical surgery with primary anastomosis is the standard treatment.

Cáncer de colon con infiltración a pared abdominal: un reto diagnóstico / Colonic cancer with infiltration to the abdominal wall: a diagnostic challenge

Se presenta el caso de una paciente mujer de 53 años procedente de Piura con un tiempo de enfermedad de 20 meses, caracterizado por dolor en sitio de herida quirúrgica por colecistectomía abierta realizada hace 3 años, asociado a presencia de una masa en dicha zona, posteriormente se absceda y comienza a drenar secreción alimentaria. Los estudios de imágenes revelaron una masa dependiente de colon transverso en contacto con estómago y pared abdominal que presentaba fistulas hacia piel. Dicha masa fue extraída durante la cirugía con resultado anatomopatológico de adenocarcinoma mucinoso de colon. El caso representó un reto diagnóstico para el equipo médico y en vista de las diversas manifestaciones clínicas del cáncer de colon, sugerimos mantenerlo presente como diagnóstico diferencial en cuadros de absceso de pared abdominal y fistulizaciones entéricas.

We present the case of a 53-year-old woman with a time of illness of 20 months, characterized by pain at the site of surgical intervention for opened cholecystectomy 3 years ago, associated with a presence of a mass in said area, with the following abscess formation and fistulization of food content. Imaging studies revealed a mass dependent of the transverse colon, in contact with stomach and abdominal wall and presenting fistulas to the skin. Said mass was extracted during surgery with anatomopathological result of mucinous colon adenocarcinoma. The case represented a diagnostic challenge for the medical team and in view of the variaty of clinical manifestations of colonic cancer, we suggest that it should be consider as a differential diagnosis in cases of abdominal wall abscess and enteric fistulas.

Opinions of South African dietitians on fistuloclysis as a treatment option for intestinal failure patients

Introduction: Intestinal failure is the consequence of diverse aetiologies and pathophysiological causes. Fistuloclysis is an effective means of nutritional support to selected intestinal failure patients. This study aimed to investigate the management of adult intestinal failure patients in hospitals in South Africa, determining how practical and acceptable fistuloclysis is.Methods: The current management of type 2 and type 3 intestinal failure patients in South African hospitals was investigated by means of occupation-specific questionnaires, evaluating perceptions and opinions among dietitians. Results: Twenty-seven dietitians indicated willingness to participate in the survey, the majority (67%) having been involved with patient management in this field for one to five years. All indicated correctly that high fistula outputs would be defined as intestinal failure. Only 47% gave the correct definition of fistuloclysis, while 28% were currently utilising it as a means of nutrition support. All respondents agreed that unsuccessful implementation of fistuloclysis was due to training shortfalls and resistance Conclusion : There is a positive perception and awareness of fistuloclysis; however, numerous stumbling blocks hamper the wider use of this novel

Nature Heals: Spontaneous Resolution of Liver Abscess through Hepato-colic Fistula.

Rupture of a liver abscess is a fairly common phenomenon in surgical practice. It is commoner in developing countries like India. Sites of rupture often predict the clinical course of the patient and affect the natural history of the disease, more common being the pleural and peritoneal cavity. Rupture into the bowel with fistulization is a rare phenomenon in liver abscess. Hepato-colic fistulae are being encountered following radiofrequency ablation for hepato cellular carcinoma. This occurring in the setting of liver abscess is highly uncommon. We report the first ever case in English literature, wherein an amoebic liver abscess was complicated by the occurrence of a hepato-colic fistula. The patient was a 48-year-old male who had a liver abscess in a background of alcoholic liver disease. On further investigation, he was found to have abnormal communication between the abscess cavity and the hepatic flexure of the colon. He was managed conservatively followed by spontaneous closure of the fistula.

Therapeutic alternatives for the treatment of infected pancreatic necrosis: an overview / Alternativas terapéuticas para el tratamiento de la necrosis pancreática infecciosa: una visión general

Despite diagnostic and therapeutic advances, the treatment of infected pancreatic necrosis (IPN) continues to be a complex problem to solve. The aim of this study is to evaluate the effectiveness of different surgical alternatives for the treatment of IPN. Articles published between 2000 to 2013, and related to effectiveness of open surgery (OS) and minimally invasive treatmente (MIT) in patients with IPN were evaluated. PubMed, MEDLINE, The Cochrane Database of Systematic Reviews, Cochrane Central Register RCT, DARE, IBECS, SciELO, LILACS, PAHO, WHOLIS, ASERNIP-S, NIHR, HTA, Clinical Excellence, York Health Economic Consortium and Tripdatabase were reviewed, searching systematic reviews (SR), randomized clinical trials (RCT) and observational studies (OST), in which the effectiveness of OS and MIT was evaluated in relation to the variables mortality, intra-abdominal bleeding, development of enterocutaneous fistula or hollow viscera perforation, development of pancreatic fistula, reoperations for complications, reoperations for new necrosectomy, development of diabetes mellitus and pancreatic enzyme requirements. Three hundred eighty-nine articles were retrieved, 10 of which met the selection criteria (2 SR, 1 RCT and 7 OST). The studies have a level of evidence of 2a, 2b, 3a and 4. MIT are associated with better results than OS in all variables analyzed, but significantly only in the development of diabetes mellitus and pancreatic enzyme requirement. Articles found are few and heterogeneous, making meaningful conclusions difficult. Studies with a better level of evidence, methodological quality and population size are needed to make conclusions and recommendations.

A pesar de los avances diagnósticos y terapéuticos, el tratamiento de la necrosis pancreática infecciosa (NPI) sigue siendo un problema complejo de resolver. El objetivo de este estudio es evaluar la eficacia de las diferentes alternativas quirúrgicas para el tratamiento del NPI. Fueron evaluados artículos publicados entre 2000 y 2013, relacionados con la efectividad de la cirugía abierta (CA) y el tratamiento mínimamente invasivo (TMI) en pacientes diagnosticados con NPI. Se PubMed, MEDLINE, The Cochrane Database of Systematic Reviews, Cochrane Central Register RCT, DARE, IBECS, SciELO, LILACS, PAHO, WHOLIS, ASERNIP-S, NIHR, HTA, Clinical Excellence, York Health Economic Consortium y Tripdatabase, en búsqueda de revisiones sistemáticas (RS), ensayos clínicos aleatorios (ECA) y estudios observacionales (EO). En estos estudios se evaluó la eficacia de la cirugía y el TMI en relación con diferentes variables, como la mortalidad, el sangrado intra-abdominal, el desarrollo de fístula enterocutánea o la perforación de víscera hueca, el desarrollo de fístula pancreática, reintervenciones por complicaciones, reintervenciones por necrosectomía, el desarrollo de diabetes mellitus y la necesidad de enzimas pancreáticas. Se consiguieron 389 artículos, de los cuales 10 cumplieron con los criterios de selección (2 RS, 1 ECA y 7 EO). Los estudios presentaron un nivel de evidencia de 2a, 2b, 3a y 4. El TMI se asocia con mejores resultados que la CA en todas las variables analizadas, pero en forma significativa sólo en el desarrollo de la diabetes mellitus y la necesidad de enzimas pancreáticas. Los artículos encontrados son pocos y heterogéneos, lo que hace difícil poder alcanzar conclusiones significativas. Se necesitan estudios con un mejor nivel de evidencia, calidad metodológica y tamaño de población estudiada para poder establecer conclusiones y recomendaciones.

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.

Hepatoduodenal fistula formation following transcatheter arterial chemoembolization and radiotherapy for hepatocellular carcinoma: treatment with endoscopic Histoacryl injection

A 71-year-old male patient was readmitted to our hospital 1 month after discharge because of relapse of abdominal pain. He had been diagnosed with hepatocellular carcinoma (HCC) 1 year prior and had undergone repeated transcatheter arterial chemoembolization and radiotherapy. During the last hospitalization, he was diagnosed with a liver abscess complicated by previous treatments for HCC and was treated with intravenous antibiotics and abscess aspiration. Follow-up abdominal computed tomography revealed a liver abscess with a duodenal fistula, which was successfully treated with endoscopic Histoacryl injection into the fistula. Liver abscesses with duodenal fistulas rarely occur, but they are intractable and possibly fatal in patients with HCC. In the literature, they have frequently been managed only with abscess treatment without fistula management. We herein report the first case of a patient with a liver abscess complicated by a fistula between the duodenum and the abscess, which was treated with endoscopic Histoacryl injection.

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.

Enfermedad de Crohn fistulizante: manejo actual y su aplicabilidad en la realidad nacional / Fistulizing Crohn’s disease, current management and its applicability in the national reality

The development of fistulas during the evolution of Crohn’s Disease represents a severe situation that affects quality of life and requires a multidisciplinary care approach that involving gastroenterologists, surgeons and radiologists. Fistulizing Crohn’s disease can be divided in perianal and not perianal disease. Perianal disease can also be divided in simple or complicated disease depending on the fistula’s characteristics that will guide the clinical and therapeutic approach. Fistulizing not perianal disease can be internal when it communicates the bowel with other organs (colovesical, rectovaginal or enteroenteric fistulas), and external when it communicates the bowel with the abdominal wall (enterocutaneous fistula), either as a spontaneous or post-surgical phenomenon. Given the variety of fistula presentation, it is necessary to give an individualized approach, taking into account the fistula’s route, the inflammatory bowel activity, the presence of abscesses, and the nutritional status of the patient. This review is focused on the current management of fistulizing Crohn’s disease in our country.

El desarrollo de fistulas durante la evolución de la enfermedad de Crohn es una situación grave que condiciona una peor calidad de vida, así como mayor complejidad en el enfrentamiento, debiendo involucrar la colaboración multidisciplinar entre gastroenterólogos, cirujanos y radiólogos. La enfermedad fistulizante se divide en aquella que afecta la zona perianal (enfermedad perianal) y en aquella que no afecta la zona perianal. La enfermedad perianal a la vez se dividirá en simple o compleja dependiendo de las características de las fistulas, lo cual condiciona variaciones en el enfrentamiento y tratamiento. La enfermedad fistulizante no perianal se divide en interna cuando comunica al intestino con otros órganos (fistulas entero-vesicales, entero-vaginales, entero-entérico) y externas cuando se comunica al intestino con la pared abdominal (fistulas entero-cutáneas) tanto de forma espontánea como postquirúrgica. Debido a la gran diversidad de presentación de las fistulas es necesario individualizar cada grupo de trayectos fistulosos, valorar la asociación a actividad inflamatoria luminal, descartar la presencia de abscesos y valorar el estado nutricional de los pacientes para definir el manejo integral adecuado. Este artículo se centra en el manejo actual de la enfermedad de Crohn fistulizante en nuestro país.

Fístula enteroatmosférica y uso del VAC: a propósito de un caso / Enteroatmospheric fistula and vaccum assited closure: report of a case

Las fístulas gastrointestinales asociadas con abdomen abierto posterior a cirugía abdominal mayor son una complicación grave. El manejo es extremadamente difícil y la mortalidad bastante alta a pesar de los modernos avances médicos. Aquellos pacientes que sobreviven al daño metabólico y fisiopatológico inicial, requieren en su mayoría cierre quirúrgico de la fístula lo cual es técnicamente complejo. Presentamos el caso de un paciente con una neoplasia de rectosigma que se abordó por laparoscopia y desarrolló una fístula enteroatmosférica sobre la incisión de Pfannestiel que se utilizó para la extracción de la pieza. Conclusión: El cierre asistido por vacío artesanal y el manejo nutricional adecuado permiten la mejoría en pacientes con fístulas complejas logrando las condiciones adecuadas para el cierre definitivo.

The gastrointestinal fistula associated to posterior open abdominal trauma or abdominal surgery implies severe complications. The handling of these cases is extremely hard and mortality is very high despite medical advances. Those patients who survive the initial metabolic and phisycopathological damages require, on most cases, a surgical closure of the fistula which is a very complex procedure technically. We describe the case of a patient with a rectosigmoid neoplasm that was addressed laparoscopically and enteroatmospheric fistula just developing on phannestiel incision was used to extract the neoplasm. Conclusion: The closure assisted by “hand made vacuum” and adequate nourishment allows recovering patients with complex fistulas to achieve adequate conditions for definitive closure.

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.

Intestinal healing in rats submitted to ethanol ingestion / Cicatrização intestinal em ratos submetidos à ingestão de etanol

PURPOSE: To study the effect of alcoholism on intestinal healing and postoperative complications in rats METHODS: One hundred and sixty rats were divided into two groups: control and treated. The control group received water and the treated group 30 percent ethanol. After 180 days, colotomy with anastomosis were performed. After, the groups were divided into four subgroups: 20 rats for study at the following moments: 4th, 7th, 14th and 21st postoperative. The analyzed parameters were: weight gain, breaking strength, tissue hydroxyproline, postoperative complications and histopathological study RESULTS: Weight gain was greater in the control group (p<0.05). When all the subgroups were clustered, breaking strength was significantly greater in the control (p<0.05). Histopathology and hydroxyproline dosage did not show differences. There were five surgical site infections in the treated group while the control group showed two (p>0.05). Nine fistulas occurred in the treated group whereas the control group two (p<0.05). There were three deaths in the control group and seven in the treated group (p>0.05). CONCLUSIONS: Treated group undergo a malnutrition process that is revealed by lower weight gain. Impaired intestinal healing as indicated by smaller breaking strength. There were a larger number of postoperative complications in the treated animals.

OBJETIVO: Estudar o efeito do alcoolismo no processo de cicatrização intestinal e suas complicações pós-operatórias em ratos. MÉTODOS: Cento e sessenta ratos foram divididos em dois grupos: tratado e controle. O controle recebeu água, enquanto o tratado etanol a 30 por cento. Após 180 dias foram realizadas colotomia, seguida de anastomose. Após os animais foram divididos em quatro subgrupos de 20 ratos para estudo nos seguintes momentos: 4º, 7º, 14º e 21º pós-operatório. Os parâmetros analisados foram: ganho de peso, força de ruptura, hidroxiprolina tecidual, complicações pós-operatórias e estudo histopatológico. RESULTADOS: O ganho de peso foi superior no grupo controle (p<0,05). Após agrupamento dos momentos a força de ruptura foi superior no controle (p<0,05). Não houve diferença quanto à histopatologia e hidroxiprolina. Houve cinco infecções de incisão no grupo tratado, enquanto no controle ocorreram duas (p>0,05). Houve nove fístulas no grupo tratado, enquanto no controle duas (p<0,05). Ocorreram sete mortes no grupo tratado e apenas três no controle (p>0,05). CONCLUSÕES: No grupo tratado ocorreu um processo de subnutrição evidenciado pelo menor ganho de peso. Piora na cicatrização intestinal, indicada pela menor força de ruptura. Ocorreu um maior número de complicações pós-operatórias no grupo tratado.

Excepcional y compleja lesión duodenal por ingesta de objetos metálicos / Duodenal perforation caused by metallic objects: case report

We report a 20 years old schizophrenic male, with a history of ingestion of four metallic tubes through which mate tea is drunk, that was admitted to the hospital with abdominal pain. A plain abdominal film showed the metallic objects in the abdominal cavity. The patient was operated. Two of the tubes were perforating the second portion of duodenum and the other two were in the large bowel. The tubes were extracted and the bowel wall was repaired. Due to a bad postoperative evolution, on a second operation, an antrectomy and duodenal excision was carried out. A duodenal fistula appeared that closed after 30 days, when the patient was discharged.

Las lesiones duodenales graves por ingestión de cuerpos extraños son excepcionales y cursan con alta morbimortalidad a pesar de los avances en el diagnóstico, su manejo quirúrgico y endoscópico. Actualmente, para su resolución definitiva se requiere a veces de un tratamiento por etapas y mediante la combinación de diversos procedimientos. Se presenta un caso clínico de lesión multivisceral a partir de una perforación duodenal (tipo III) provocada por la ingesta de varios objetos metálicos (bombillas de mate), que asocia compromiso hepático y colónico y complicada con una fístula duodeno cutánea. Su manejo requirió de varios procedimientos de reparación duodenal, que se combinaron en etapas sucesivas. El excepcional tipo de agente lesional, la compleja situación que provocó y el análisis de la literatura, otorgan particular interés al tema.
