ABSTRACT
Resumen Se reporta el caso de un hombre de 25 años con diagnóstico de tumor de células germinales no seminomatoso que ingresó a urgencias por cuadro clínico de dolor abdominal difuso asociado con distensión y múltiples episodios eméticos. Ante la sospecha clínica de obstrucción intestinal se realizó una tomografía abdominal contrastada que mostró una obstrucción en la tercera porción duodenal por compresión extrínseca ocasionada por múltiples conglomerados retroperitoneales. Se decidió el tiempo quirúrgico para una derivación gastrointestinal en la que se realizó una gastroyeyunoanastomosis por técnica convencional; hacia el quinto día posoperatorio presentó un deterioro clínico dado por episodios febriles, dolor abdominal y taquicardia. Se realizó una nueva tomografía abdominal que reportó una colección intraabdominal en el flanco izquierdo de 12 x 12 x 5 cm secundaria a proceso fistuloso yeyunal, se realizó un manejo de la colección con drenaje percutáneo por radiología intervencionista y alojamiento de catéteres de drenaje, y se realizó una esofagogastroduodenoscopia con el fin de ejecutar una técnica de exclusión pilórica con dispositivo Ovesco (over-the-scope) como manejo de la fístula yeyunal, con la que se obtuvo éxito técnico. Durante el posoperatorio se realizó como seguimiento una radiografía de vías digestivas que confirmó la no continuidad pilórica con adecuada permeabilidad de la gastroyeyunoanastomosis, y una tomografía abdominal contrastada que mostró una disminución de la colección intraabdominal sin extravasaciones del medio de contraste. El desenlace favorable de este caso sugiere la utilidad del dispositivo Ovesco en casos de fístulas del tracto gastrointestinal proximal, sobre todo en aquellos pacientes con múltiples comorbilidades o mal estado general que se favorecen de procedimientos mínimamente invasivos que disminuyan el riesgo de desenlace fatal.
Abstract A 25-year-old man diagnosed with a non-seminomatous germ cell tumor was admitted to the emergency department for diffuse abdominal pain associated with bloating and multiple emetic episodes. Due to the clinical suspicion of intestinal obstruction, a contrasted abdominal tomography was performed, showing an obstruction in the third duodenal portion resulting from extrinsic compression caused by multiple retroperitoneal conglomerates. Surgical time was scheduled for a gastric bypass surgery where gastrojejunostomy was performed using conventional technique. On the fifth postoperative day, he presented clinical deterioration due to febrile episodes, abdominal pain, and tachycardia. A new abdominal tomography was performed, reporting an intra-abdominal collection of pus on the left flank of 12 x 12 x 5 cm secondary to the jejunal fistula process. Hence, percutaneous drainage management of the collection was performed by interventional radiology and drainage catheter placement. In addition, an EGD was performed to conduct a pyloric exclusion technique with an Ovesco (over-the-scope-clip) device for managing the jejunal fistula, which was technically successful. A gastrointestinal tract X-ray was performed as a follow-up during the postoperative stage, showing no pyloric continuity with adequate patency of the gastrojejunostomy. In addition, a contrasted abdominal CT scan showed a decrease in the intra-abdominal collection without extravasation of the contrast medium. This case outcome suggests the Ovesco device may be helpful in proximal GI fistulas cases, especially in patients with multiple comorbidities or poor general conditions who may benefit from minimally invasive procedures decreasing the risk of fatal outcomes.
ABSTRACT
Las fístulas gastrointestinales asociadas con abdomen abierto posterior a trauma o cirugía abdominal mayor son una complicación grave. El manejo es extremadamente dífícil 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 y pobremente descrito en la literatura. Presentar una técnica efectiva para controlar la contaminación de la pared abdominal y el drenaje de las fístulas en pacientes con abdomen abierto. Se describen dos casos de pacientes con fístulas complejas de alto gasto y abdomen abierto quienes recibieron soporte nutricional y manejo con VAC artesanal. La literatura internacional describe el uso del cierre asistido por vacío (VAC) en el manejo de fístulas en pacientes con abdomen abierto. Se instauró un sistema de VAC "artesanal" utilizando una bomba de aspiración Medi-Pump modelo 1130, gasa vaselinada y/o goma espuma estéril y tubo de tórax 32. Para lograr el vacío se cubrió el abdomen con "envoplast". Ambos pacientes evolucionaron favorablemente, se logró recuperar el estado nutricional, controlar la infección, el gasto de la fístula y mejorar notablemente las condiciones locales. En uno de los casos se logró el cierre espontáneo de la fístula y el otro fue intervenido realizándose cierre quirúrgico. El cierre asistido por vacío artesanal y el manejo nutricional adecuado permite la mejoría en pacientes con fístulas complejas logrando las condiciones adecuadas para el cierre definitivo.

Gastrointestinal (GI) fistulas are frequently very serious complications that are associated with high morbidity and mortality. GI fistulas can cause a wide array of pathophysiological effects by allowing abnormal diversion of the GI contents, including digestive fluid, water, electrolytes, and nutrients, from either one intestine to another or from the intestine to the skin. As an alternative to surgery, recent technical advances in interventional radiology and percutaneous techniques have been shown as advantageous to lower the morbidity and mortality rate, and allow for superior accessibility to the fistulous tracts via the use of fistulography. In addition, new interventional management techniques continue to emerge. We describe the clinical and imaging features of GI fistulas and outline the interventional management of GI fistulas.

Among the common foreign bodies that are ingested by children, ingesting multiple magnets is known to be hazardous due to the gastrointestinal complications caused by the magnets attracting each other across the bowel walls. We present here a case of gastrojejunal fistula and jejunal rotation that was caused by two ingested magnets in a 5-year-old girl, and we also present the findings of simple abdomen radiography, a small bowel series and computed tomography. The unchanged position of the radiopaque metallic foreign bodies on the serial abdominal radiographs suggests the inadvertent ingestion of multiple magnets.

Objective To study a new stuff-block therapy method to promote closure of external gastrointestinal fistula. Methods Twenty-eight patients with different type of external gastrointestinal fistulae in different sites were treated with fibrin glue stuff-blocking technique. The fibrin glue dispensary system designed by the authors has a double-lumen catheter in different size.When the catheter inserted via the fistula to about 1cm from the intestinal fistula,the glue was relased through the catheter to seal the whole fistula. Results The insertion of dispensary catheter into the fistulae was successful in all the cases. No side-effect was observed in all the patients. In 17 patients the fistulae healed about one week after one time treatment, 11 patients′ fistulae healed in about two weeks after 2-3 time treatment. Twenty-five patents were followed up for 3-6 months . The fistula sustained healing and normal deal was restored.Conclusions Stuff-blocking of the fistula with fibrin glue by means of the dispensary system designed by the authors has satisfy results. It provided a new method for the treatment of external gastrointestinal fistula .
ABSTRACT
PURPOSE: To evaluate the preoperative diagnostic concordance of morphologic classification of anorectal fistula by endoanal ultrasonography (EUSG) and endoanal magnetic resonance imaging (EMRI). MATERIALS AND METHODS: Between January 1998 and March 1999, 17 patients with anorectal fistula underwent endoanal ultrasonography and magnetic resonance imaging for preoperative assessment. The types of fistula and abscess formation were evaluated, and the findings compared with those obtained during surgery. RESULT: The overall accordance of anorectal fistula was 76% (13 of 17 cases) on ultrasonography and 94% (16 of 17 cases) on magnetic resonance imaging. According to the findings of EUSG, the accordance of each type of anorectal fistula was as follows: transphineteric, 92% (11 of 12 cases); suprasphinteric, 33% (1 of 3); and extrasphincteric, 50% (1 of 2), while for EMRI, the respective figures were 100% (12 of 12 cases), 67% (2 of 3), and 100% (2 of 2). An analysis of reproducibility using kappa value showed that overall concordance between endoanal ultrasonography and surgery(K=0.820) as well as between endoanal MRI and surgery (K=0.866), was very close. CONCLUSION: For the evaluation of anorectal fistula, preoperative endoanal magnetic resonance imaging was more accurate and informative than endoanal ultrasonography.

PURPOSE: To evaluate the usefulness of CT in patients with gastrointestinal fistula. MATERIALS AND METHODS: We retrospectively reviewed the CT scans of 17 patients with various type of gastrointestinal fistula. The presence of these fistulae was confirmed by laparotomy in seven patients and by barium studies in fifteen. We evaluated the diagnostic accuracy of CT in these cases, and in correlation with barium studies and surgical findings, subsequently analyzed the CT findings. We determined the presence or absence of fistula tract, flow diversion of oral contrast media, bowel wall changes adjacent to the fistula tract, and extraluminal manifestations such as soft tissue mass, free air, leakage of oral contrast media, and peritoneal changes. RESULTS: The diagnosis of gastrointestinal fistula was possible on CT in nine (53%) of the 17 patients by using the CT criteria of direct visualization of the fistula tract (n=6) or flow diversion of oral contrast media (n=4). Other ancillary findings included bowel wall thickening adjacent to fistula tract in 15 patients, extraluminal soft-tissue mass in five, extraluminal free air in ten, extraluminal contrast leakage in four, and varying degrees of mesenteric and/or omental infiltration in 15. CONCLUSION: CT scanning is useful for the diagnosis of gastrointestinal fistula, which may be possible if the fistula tract and flow diversion of oral contrast materials are seen. It is also useful for evaluation of the extent of the etiologic disease.

Enteric fistulae result from gastrointestinal perforations in which communication is established between the site of perforation and another hollow viscus, potential space, or skin surface. Certain types of enteric fistulae are difficult to demonstrate by conventional radiographic methods, and CT is unique in its ability to demonstrate the extent and nature of extraluminal changes. The purpose of this study is to illustrate the CT findings of enteric fistulae occurring in a variety of abdominal and pelvic organs.
