Caracterización de las fístulas enterocutáneas posoperatorias / Characterization of Postoperative Enterocutaneous Fistulas

Introducción: Las fístulas enterocutáneas representan una enfermedad grave que deben afrontar un gran número de cirujanos durante el ejercicio de la profesión. El tratamiento suele ser extremadamente complejo y siempre requiere de una intervención multidisciplinaria adaptada para cada caso en particular. Objetivo: Evaluar las características clínico-epidemiológicas y terapéuticas de las fístulas enterocutáneas posoperatorias. Métodos: Se realizó un estudio observacional, descriptivo, con recogida prospectiva de datos en el quinquenio 2013-2017. El universo fue de 28 pacientes diagnosticados con fístula enterocutánea posoperatoria y se usaron las variables: edad, sexo, carácter de la intervención, diagnóstico operatorio, tipo de fístula, tratamiento definitivo, complicaciones y pilares de tratamiento. Resultados: La edad media fue de 49 años. Las fístulas fueron más frecuentes en el sexo femenino (53,57 por ciento). El 78,57 por ciento de los pacientes fueron intervenidos con carácter de urgencia, y el 25 por ciento tuvieron un diagnóstico operatorio de oclusión intestinal mecánica por bridas seguida de la oclusión intestinal por tumor de colon izquierdo (17,86 por ciento). La hemicolectomía izquierda con anastomosis término-terminal (21,43 por ciento) y la resección intestinal con anastomosis término-terminal (17,86 por ciento) fueron los principales procedimientos quirúrgicos realizados. Conclusiones: Las fístulas de tipo II y de bajo gasto prevalecieron en la serie de casos en una media de tiempo que se corresponde con lo reportado en la literatura. La infección del sitio quirúrgico fue la complicación más observada y los pilares del tratamiento fueron cumplidos en la mayoría de los pacientes prevaleciendo el cierre espontáneo como tratamiento definitivo(AU)

Introduction: Enterocutaneous fistulas are a serious disease that a large number of surgeons must face during the practice of their profession. Their treatment is usually extremely complex and always requires a multidisciplinary intervention adapted to each particular case. Objective: To evaluate the clinical-epidemiological and therapeutic characteristics of postoperative enterocutaneous fistulas. Methods: An observational and descriptive study was performed, with prospective data collection, in the five-year period 2013-2017. The study universe was 28 patients diagnosed with postoperative enterocutaneous fistula. The following variables were used: age, sex, nature of the intervention, operative diagnosis, type of fistula, definitive treatment, complications and treatment cornerstones. Results: The mean age was 49 years. Fistulas were more frequent in the female sex (53.57 percent). 78.57 percent of the patients underwent emergency surgery, while 25 percent had an operative diagnosis of mechanical intestinal occlusion due to adherences, followed by intestinal occlusion due to left colon tumor (17.86 percent). Left hemicolectomy with end-to-end anastomosis (21.43 percent) and intestinal resection with end-to-end anastomosis (17.86 percent) were the main surgical procedures. Conclusions: Type II and low-output fistulas prevailed in the case series at a mean time that corresponds to that reported in the literature. Surgical site infection was the most frequently observed complication, while the treatment cornerstones were fulfilled in most patients, with spontaneous closure prevailing as a definitive treatment(AU)

Colorenal fistula and urinary tract infection in a pediatric patient with acute lymphoblastic leukemia. / Fístula colorrenal e infección de vías urinarias en paciente pediátrico con leucemia linfoide aguda.

INTRODUCTION: Colorenal fistula is rare in the pediatric population. It may occur at any segment involved by ischemia, chronic inflammation, or necrosis. It is typically associated with a preliminary renal lesion that may arise as a result of interventional procedures, inflammatory conditions, colon tumor, and xanthogranulomatous pyelonephritis, among others. CASE REPORT: 15-year-old female patient diagnosed with acute lymphoblastic leukemia admitted at our institution for baseline condition management. During her stay, she experienced gastrointestinal and urinary infectious events. In the assessment and management of those, a left colorenal fistula was found. Surgical treatment was decided upon. DISCUSSION: Colorenal fistula typically occurs secondary to renal inflammation or infection. Clinical signs are highly variable, and treatment is surgical, with the fistulous tract being resected in all cases.

INTRODUCCION: Las fístulas colorrenales son infrecuentes en la población pediátrica. Pueden desarrollarse en cualquier segmento afectado por isquemia, inflamación crónica o necrosis. Suelen estar asociadas a una lesión primitiva en el riñón que puede producirse por procedimientos intervencionistas, enfermedades inflamatorias, tumorales del colon, pielonefritis xantogranulomatosa, entre otras. CASO CLINICO: Paciente femenina de 15 años, con diagnóstico de leucemia linfoide aguda, ingresa a la institución para recibir manejo de su enfermedad de base. Durante su evolución, desarrolla eventos infecciosos (gastrointestinales y urinarios), y en evaluación y manejo de estos se documenta fístula colorrenal izquierda, motivo por el cual se da un enfoque de tratamiento quirúrgico. COMENTARIOS: La fístula renocólica generalmente se presenta secundaria a procesos inflamatorios o infecciosos renales; su presentación clínica es muy variada, y el tratamiento es quirúrgico, incluyendo siempre la resección del trayecto fistuloso.

Fístula aorto-duodenal primaria: caso clínico / Primary aorto-duodenal fistula: clinical case

Resumen Introducción Las fístulas aorto-entéricas (FAE) son una causa infrecuente de hemorragia digestiva. El pronóstico, generalmente ominoso, depende de una alta sospecha clínica y diagnóstico oportuno. Caso clínico Reportamos el caso de una mujer de 66 años intervenida por un aneurisma sacular aórtico abdominal (AAA) yuxtarrenal, con rotura contenida, fistulizado al duodeno. Presentó una hemorragia digestiva en el preoperatorio; sin embargo, el diagnóstico de la fístula se hizo en el intraoperatorio. La paciente fue sometida a reparación quirúrgica urgente con instalación de una prótesis aórtica bifemoral y resección duodenal. En el postoperatorio inmediato presentó una trombosis parcial de las ramas de la prótesis aórtica e isquemia de extremidades, siendo reintervenida exitosamente. Discusión La FAE es una causa potencialmente fatal de hemorragia digestiva. El diagnóstico continúa siendo un desafío debido a su presentación inespecífica y siempre debiese ser considerado frente a una hemorragia digestiva sin causa aparente. Existen varias opciones para el enfrentamiento quirúrgico que deben ser analizadas caso a caso, sin retrasar la reparación de la fístula. Es preferible la resección duodenal ante la simple duodenorrafia.

Introduction Aorto-enteric fistulae (AEF) are a rare cause of gastrointestinal bleeding. The prognosis tends to be ominous, depending greatly in a high level of clinical suspicion and prompt diagnosis. Clinical case We report a case of a 66-year-old female with a saccular juxta-renal abdominal aortic aneurysm (AAA), with a contained rupture. The patient was urgently submitted to surgical repair using an bifemoral aortic prosthesis. A duodenal partial resection was performed. During the immediate postoperative time she presented partial thrombosis of prosthesis and ischemia of lower extremities so she was reoperated successfully. Discussion AEF is a potentially fatal cause of gastrointestinal bleeding. Diagnosis is still troublesome due to its vague presentation and it should always be considered when facing gastrointestinal haemorrhage with no apparent cause. There are several surgical approaches that should be pondered case to case without delaying the repair of the defect.

Biliary ileus: case report.

Biliary ileusis a uncommon cause of mechanical bowel obstruction, affecting older adult patients who often have other significant medical conditions. It is caused by intestinal impaction of a gallstone that enters the bowel via a cholecysto-enteric fistula. The mortality rate is considerable, ranging between 12 and 27%. Treatment in most cases is surgical, aimed at the resolution of the intestinal obstruction. We report the case of a 55 year old patient diagnosed with biliary ileus, wich evolved without complications after a enterolithotomy. We have concluded, based on the literature that an early diagnosis associated with appropriate therapy can lead to a better prognosis.

Colovesical fistula secondary to hernia mesh migration: an unusual incident / Fístula colovesical secundária à migração da malha para reparo de hérnia: um incidente incomum

ABSTRACT We evaluated a 27-year old male with pneumaturia and fecaluria with a past history of right inguinal hernia repair. Though, cystoscopy and contrast enhanced computed tomography did not furnish any evidence to arrive at a diagnosis, interestingly, colonoscopy revealed a mesh in the sigmoid colon making apparent the diagnosis of colovesical fistula secondary to mesh migration. Later, surgical removal of the mesh from the sigmoid colon with rent closure of the fistulous opening was done successfully. Our case thus, highlights the vital role of common diagnostic tool like colonoscopy in making an uncommon diagnosis.

RESUMO Avaliamos um homem de 27 anos com pneumaturia e fecalúria com antecedentes de reparo da hérnia inguinal direita. Embora a cistoscopia e a tomografia computadorizada com contraste (TCC) não tenham fornecido nenhuma evidência para obter-se um diagnóstico, curiosamente, a colonoscopia revelou uma malha no cólon sigmoide, estabelecendo o diagnóstico de fístula colovesical (FCV) secundária à migração da malha. Mais tarde, foi feita a remoção cirúrgica da malha do cólon sigmoide com fechamento da abertura fistulosa com sucesso. Nosso caso, portanto, destaca o papel vital de uma ferramenta diagnóstica comum, como a colonoscopia, para obter-se um diagnóstico incomum.

Cholecystoduodenal fistula, an infrequent complication of cholelithiasis: Our experience in its surgical management. / Fístula colecistoduodenal, complicación infrecuente de litiasis vesicular: nuestra experiencia en su manejo quirúrgico.

INTRODUCTION: Bilioenteric fistulas are the abnormal communication between the bile duct system and the gastrointestinal tract that occurs spontaneously and is a rare complication of an untreated gallstone in the majority of cases. These fistulas can cause diverse clinical consequences and in some cases be life-threatening to the patient. AIM: To identify the incidence of bilioenteric fistula in patients with gallstones, its clinical presentation, diagnosis through imaging study, surgical management, postoperative complications, and follow-up. MATERIALS AND METHODS: A retrospective study was conducted to search for bilioenteric fistula in patients that underwent cholecystectomy at our hospital center due to cholelithiasis, cholecystitis, or cholangitis, within a 3-year time frame. RESULTS: Four patients, 2 men and 2 women, were identified with cholecystoduodenal fistula. Their mean age was 81.5 years. Two of the patients presented with acute cholangitis and 2 presented with bowel obstruction due to gallstone ileus. All the patients underwent surgical treatment and the diagnostic and therapeutic management of each of them was analyzed. CONCLUSIONS: The incidence of cholecystoduodenal fistula was similar to that reported in the medical literature. It is a rare complication of gallstones and its diagnosis is difficult due to its nonspecific symptomatology. It should be contemplated in elderly patients that have a contracted gallbladder with numerous adhesions.

Delayed Presentation of Jejuno-Jejunal Fistula With Stricture After Physical Child Abuse.

Small intestinal injury is seldom described in the context of child abuse. Signs and symptoms are subtle, often leading to delays in diagnosis. We describe a 3-year-old boy initially admitted with severe blunt abdominal trauma from physical child abuse. He was successfully managed nonoperatively. The child was then hospitalized several times for nonspecific abdominal symptoms until diagnostic laparoscopy discovered a jejunal stricture with a proximal jejuno-jejunal fistula. Symptoms fully resolved after resection. Delayed presentation of small intestinal injury should remain on the differential diagnosis in the evaluation of persistent abdominal symptoms in a child with a prior history of physical abuse, even if imaging studies do not reveal specific abnormalities.

Gastrocolic fistula secondary to adenocarcinoma of the transverse colon: a case report.

INTRODUCTION: Gastrocolic fistula is a rare complication of adenocarcinoma of the colon. Despite radical resections, these patients usually have a poor prognosis with a mean survival of 23 months and long-term survival is rarely reported. CASE PRESENTATION: A 48-year-old Latino-American man presented with watery diarrhea, diffuse abdominal pain and weight loss for 3 months. A computed tomography scan revealed a mass in the splenic flexure that had infiltrated his stomach and diaphragm. Panendoscopy and colonoscopy confirmed the presence of a fistula between the distal transverse colon and the stomach, which was secondary to a colon cancer. His colon, stomach and left diaphragm were resected en bloc. A histological examination revealed a moderately differentiated adenocarcinoma of the colon that had infiltrated the full width of the gastric wall with 37 negative lymph nodes and clear surgical margins. Adjuvant chemotherapy with capecitabine and oxaliplatin was administered after surgery. Our patient is alive and without any recurrence 5 years after surgery. CONCLUSIONS: En bloc resection with adjuvant chemotherapy offers the best treatment option for gastrocolic fistulas. This is one of the patients with greater survival reported in the medical literature.

Repair of aortoenteric fistula secondary to graft placement for middle aortic syndrome.

When an aortoenteric fistula (AEF) arises secondary to suprarenal or more proximal aortic repair, mortality and the complexity of the surgery increases. We present the first reported case to our knowledge of a secondary AEF arising 13 years after surgical repair of middle aortic syndrome. We performed the original surgery on a 22-year-old male who presented with hypertension and claudication by placing a Dacron prosthetic patch on the juxtarenal and infrarenal aorta, bilateral vein bypasses to the left and right renal artery, and a Dacron bypass to the proximal superior mesenteric artery. Thirteen years later, he presented with massive gastrointestinal bleeding and syncope. We performed a distal descending thoracic aortic rifampin-soaked bifurcated Dacron graft to the left renal artery and to a large meandering mesenteric artery followed by excision of all previous prosthetic graft and insertion of a rifampin-soaked tube graft from the distal descending thoracic aorta to the distal abdominal aorta with omental flap coverage. After a complicated postoperative course, he was discharged 2 months later and remains on dialysis at his 6-month postoperative follow-up without evidence of recurrent infection.

[Sigmoido-buttock fistula by diverticulitis: report of a rare complication]. / Fístula sigmoideo-glútea por diverticulitis. Reporte de una rara complicación.

INTRODUCTION: The complicated diverticulitis of the colon is characterized by its association with abscesses, bleeding, stenosis, perforation, obstruction or fistula. We report a case of spontaneous sigmoido-cutaneous fistula from diverticulitis to an unusual place in the gluteal region. CLINICAL CASE: A 59-year-old male patient presented an inflammatory wound in left buttock without response to the conservative medical treatment. The fistulography, colonoscopy, barium enema and computed tomography showed a sigmoido-cutaneous fistula to the left buttock from diverticulitis. The biopsy of the lesion ruled out malignancy. We performed an elective sigmoid resection with primary colorectal anastomosis, partial fistulectomy and injection of a fibrin sealant in the residual tract. DISCUSSION: The colon-cutaneous fistulas from diverticulitis are relatively rare. We report a spontaneous fistula with origin in a single diverticulum in the sigmoid colon and that drained through the piriform fossa of the pelvic floor to the skin of the left buttock. CONCLUSIONS: A high index of suspiscion is necessary to not confuse the colo-buttock fistula with local abscesses.
