RESUMO

INTRODUCTION: There is no information in the literature about surgical outcome of the distal splenorenal shunt (Warren shunt) in those patients with anomalous flow in the left renal vein to the inferior vena cava. OBJECTIVE: The purpose of this manuscript was to evaluate the incidence of thrombosis in the Warren shunt in those patients with anomalous flow in the left renal vein to the inferior vena cava. METHODS: We performed a prospective, descriptive and longitudinal study in those patients who performed a surgical procedure to the treatment of hemorrhagic portal hypertension in a tertiary referral center in Mexico City during a one year period (2002-2003). Before the surgical procedure an arterial and venous angiographic study was done including celiac axis, superior mesenteric artery and splenic artery. The patients were scheduled in the outpatient office the first, third, sixth month and the year after the surgical procedure. We looked in them for gastrointestinal bleeding secondary to portal hypertension. In those patients with Warren shunt an angiographic study was done during the first month after the surgical procedure. RESULTS: Twenty eight patients were included, 17 of them women (60.7%). Median patient age was 48 years old. In 20 patients a Warren shunt were done and in eigth patients a devascularization operation were done. The anomalous flow of the left renal vein was identified in nine patients (28.7%). In seven of them a Warren shunt were done and in two of them a devascularization operation were done. We didn't find gastrointestinal bleeding or thrombosis of the Warren shunt in any of these patients. CONCLUSION: In those cases of patients with anomalous flow in the left renal vein a Warren shunt can be performed. In this study we didn't find thrombosis of the shunt or gastrointestinal bleeding. In this way a surgical decompression of the portal system can be done preventing bleeding episodes.

RESUMO

UNLABELLED: Transplant renal artery stenosis (TRAS) is a cause of severe post transplant hypertension with a widely variable reported incidence from 1 to 25%. We herein report 3 cases of endoluminal stent placement after percutaneous transluminal angioplasty for treatment of TRAS. Clinical and laboratory findings during their follow-up, suggestive of TRAS included: elevated mean blood pressure, bruit over the graft area(2/3), and increase in serum creatinine (2/3). Doppler sonography, radioisotope renography and arteriography were performed to confirm TRAS diagnosis. The series includes 2 female and 1 male patients; the time elapsed between transplantation and TRAS diagnosis was 25 d, 12 and 65 months, respectively. All grafts were from living related donors. Patients received at least 3 antihypertensive drugs without adequate blood pressure control. Vascular anastomosis was end to end from the renal to the hypogastric artery in two cases, and end to side to the external iliac artery in the other one. After the diagnosis of TRAS, percutaneous transluminal angioplasty with endoluminal metallic Palmaz stent placement was accomplished in the three cases. No complications occurred during or after the procedures. Beneficial clinical results were obtained in all cases documented by a decrease in both: serum creatinine, and mean blood pressure. Average follow-up after stent placement was 13, 19 and 36 months, respectively without evidence of stenosis recurrence CONCLUSIONS: Percutaneous transluminal angioplasty with stent placement is a safe and effective treatment for TRAS associated hypertension and renal dysfunction. Extended follow-up is necessary to evaluate long-term efficacy and safety of this procedure.

RESUMO

OBJECTIVE: Biliary duct lesions have a prevalence of 0.3-0.6% This prevalence is independent of the learning curve: The present paper evaluated survival and quality of life of patients following operative repair. METHODS: In a 12-year period, 180 patients underwent bile duct reconstruction. Of these patients (61 males and 129 females, mean age 39 years), 52% sustained injury during open operation and 42% during laparoscopic procedure. Quality of life was evaluated in the postoperative period. RESULTS: All 180 patients were treated surgically by means of Roux en Y hepaticojejunostomy. Transhepatic stents were used in 142 patients. Eight patients had independent left and right duct anastomosis and in 51 cases, partial resection of segment IV of liver to improve exposure of hilus was carried out. Mortality was 1.7%, due to multiorganic failure. After removal of stent, radiologic manipulation was required in 16% of cases to remove debris and stones or to dilate anastomosis. A total of 83% of patients were completely rehabilitated both clinically and biochemically. CONCLUSIONS: Bile duct injury has a good prognosis in specialized tertiary-care centers. Roux en Y hepatoyeyunostomy is procedure of choice with trans-hepatic stent when needed. Full rehabilitation can be achieved in 80% of patients.

RESUMO

Se presentan 45 pacientes que fueron tratados con el procedimiento de Sugiura, habiéndose llevado a cabo un total de 68 cirugías. Se dividieron en dos grupos: 1) Situación de Urgencia y 2) Situación Electiva. La mortalidad operatoria global en los pacientes sometidos a cirugía de urgencia fue de 62%. La incidencia de hemorragia recurrente por ruptura de várices esofágicas y de encefalopatía fue de 0%. En el grupo de pacientes sometidos a cirugía electiva, la mortalidad operatoria global fue de 16.6%. No se presentó ningún caso de hemorragia recurrente por ruptura de várices esofágicas y la encefalopatía se presentó sólo en uno de los casos. Se concluye que al operación de Sugiura es un procedimiento efectivo para el control de la hemorragia por hipertensión portal en aquellos pacientes en los que no fue posible llevar a cabo una cirugía derivativa

RESUMO

Desde 1973 se iniciaron en el Instituto Nacional de la Nutrición Salvador Zubirán las derivaciones portosistémicas selectivas para el control de la hemorragia por hipertensión portal. Se reportan 10 años de experiencia en 139 operaciones de tipo selectivo (Warren clásica, reno-esplénica término terminal y espleno-cava) practicadas de 1973 a 1983. Se practicaron 130 cirugías en situación electiva y 9 en situación de urgencia. Se encontraron 85 casos en el grupo de A de Child, 42 en el grupo B y 12 en el grupo C. La mortalidad operatoria en el grupo de emergencia fue de 44% y del grupo electivo de 13%. La ascitis y la insuficiencia hepática transitoria fueron las complicaciones más frecuentes en el postoperatorio inmediato. La encefalopatía hepática a largo plazo fue de 15%. La sobrevida a 5 años de 65%

RESUMO

El cortocircuito intrahepático es aquella fracción del flujo de la vena porta y de la arteria hepática que no pasa por los sinusoides hepáticos debido a la presencia de comunicaciones vasculares entre estos elementos y las venas hepáticas, dirigiendo dicho flujo sanguíneo directamente a la circulación general. El aumento de cortocircuitos puede tener alguna relación pronóstica con la presencia de encefalopatía y hemorragia posterior a cirugía de hipertensión portal. Incluso, se ha tratado de relacionar con la mortalidad operatoria y sobrevida a largo plazo. En nuestra institución se llevó a cabo un estudio de 74 pacientes en donde se practicaron determinaciones de cortocircuitos por arteria hepática y vena porta. Los valores encontrados para la arteria hepática fueron de 12.98 + ou - 11.44% en el grupo de pacientes operados (I) y de 7.56 + ou - 5.9% en el grupo no operado (II). Los valores para la vena porta fueron de 35.19 + ou - 19.26% en el grupo I y de 39.5 + ou - 29.09% en el grupo II. No hubo diferencia estadísticamente significativa entre ambos grupos al comparar la frecuencia de hemorragia, mortalidad operatoria y sobrevida a largo plazo. Sin embargo, en los resultados por vena porta se observa que el 70% de los pacientes que presentaron encefalopatía postoperatoria tenían un promedio de cortocircuitos de 55.5%. Se concluye que en los pacientes con hepatopatía experimentan elevación de los cortocircuitos intrahepáticos. Hay una mayor frecuencia de encefalopatía postoperatoria en aquellos casos que tienen más de 35% de cortocircuitos por vena porta. Se puede decir que el tipo de cortocircuitos es útil como parámetro para seleccionar el tipo de cirugía derivativa en el manejo del enfermo con hipertensión portal hemorrágica
