Benign biliary strictures refractory to standard bilioplasty treated using polydoxanone biodegradable biliary stents: retrospective multicentric data analysis on 107 patients.

OBJECTIVES: To assess mid-term outcome of biodegradable biliary stents (BBSs) to treat benign biliary strictures refractory to standard bilioplasty. METHODS: Institutional review board approval was obtained and patient consent was waived. 107 patients (61 males, 46 females, mean age 59 ± 16 years), were treated. Technical success and complications were recorded. Ninety-seven patients (55 males, 42 females, aged 57 ± 17 years) were considered for follow-up analysis (mean follow-up 23 ± 12 months). Fisher's exact test and Mann-Whitney U tests were used and a Kaplan-Meier curve was calculated. RESULTS: The procedure was always feasible. In 2/107 cases (2 %), stent migration occurred (technical success 98 %). 4/107 patients (4 %) experienced mild haemobilia. No major complications occurred. In 19/97 patients (18 %), stricture recurrence occurred. In this group, higher rate of subsequent cholangitis (84.2 % vs. 12.8 %, p = 0.001) and biliary stones (26.3 % vs. 2.5 %, p = 0.003) was noted. Estimated mean time to stricture recurrence was 38 months (95 % C.I 34-42 months). Estimated stricture recurrence rate at 1, 2, and 3 years was respectively 7.2 %, 26.4 %, and 29.4 %. CONCLUSION: Percutaneous placement of a BBS is a feasible and safe strategy to treat benign biliary strictures refractory to standard bilioplasty, with promising results in the mid-term period. KEY POINTS: • Percutaneous placement of a BBS is 100 % feasible. • The procedure appears free from major complications, with few minor complications. • BBSs offer promising results in the mid-term period. • With a BBS, external catheter/drainage can be removed early. • BBSs represent a new option in treating benign biliary stenosis.

Solitary fibrous tumor of the liver. Case report and review of the literature.

Solitary fibrous tumor (SFT) is a rare mesenchymal tumor. Given its origin, it can appear in almost any location. In the literature, only 50 cases of SFT in the liver parenchyma have been reported. Despite its rarity, this entity should be included in the differential diagnosis of liver masses. We report the first case with imaging data from five years prior to diagnosis, which was treated by right portal embolization and arterial tumor embolization, and subsequent liver resection. We also present an exhaustive review of the cases described to date.

Tumor fibroso solitario hepático. Descripción de un caso y revisión de la literatura / Solitary fibrous tumor of the liver. Case report and review of the literature

El tumor fibroso solitario (TFS) es una neoplasia mesenquimal infrecuente. Dado su origen, puede aparecer en prácticamente cualquier localización. En la literatura sólo hay 50 casos descritos de TFS localizado en el parénquima hepático. A pesar de su rareza, debe ser considerada dentro del diagnóstico diferencial de una masa hepática. Presentamos el primer caso con seguimiento por imagen desde 5 años antes del diagnóstico, tratado mediante embolización portal derecha y embolización arterial tumoral con posterior resección hepática, así como una revisión exhaustiva de los casos descritos hasta la actualidad

Acute mesenteric ischemia: Utility of endovascular techniques.

INTRODUCTION: Acute mesenteric ischemia (AMI) has a high mortality. Early diagnosis and treatment are very important. In our institution there is a therapeutic protocol that includes endovascular techniques (ET) in patients with AMI without peritoneal irritation at diagnosis. The aim of this study was to evaluate the use of ET in conjunction with conventional surgery in the management of potentially reversible IMA diagnosed by computed tomography (CT-angiography). METHODS: Observational, descriptive and retrospective study that evaluated the use of ET in patients with AMI (arterial origin) in 2 periods (before and after the application of a protocol that includes ET), between 2009-2013. All patients were diagnosed by a CT-angiography, as the diagnostic technique of choice, because of the clinical and analytical suspicion. RESULTS: Our series included 73 patients with IMA diagnosed by CT-angiography (45: 2009-2011; 28: 2012-2013). Leukocytosis was common (82%), high lactate levels are less frequent (47% vs. 53%). There were 49 patients with IMA without peritoneal irritation. In 51% bowel resection surgery was performed (44% survival); 18%: revascularization by ET (survival 67%); 31%: palliative treatment (0% survival). 33% of patients undergoing first-line RVI needed a surgical rescue (bowel resection). The overall mortality was 67% (2009-2011) vs. 62% (2012-2013). CONCLUSIONS: Since the protocol application, there is a higher indication of ET in patients with AMI without peritoneal irritation, showing a decreased mortality. With ET application, there is a higher survival in these patients. In our experience, the use of ET in cases of AMI without peritoneal irritation at diagnosis, may increase survival.

Manejo conservador de un hematoma subcapsular hepático en un síndrome de HELLP / Conservative management of a subcapsular liver hematoma in HELLP syndrome

La sospecha clínica, el diagnóstico rápido y un abordaje multidisciplinar son fundamentales para mejorar la morbimortalidad de las pacientes con hematoma subcapsular hepático. El tratamiento de esta entidad abarca desde la conducta expectante bajo vigilancia clínica y radiológica, la embolización de las arterias hepáticas o la cirugía en caso de inestabilidad hemodinámica, persistencia de sangrado o incremento del dolor. Presentamos el caso de un síndrome de HELLP posparto complicado con un hematoma subcapsular hepático y que se resolvió exitosamente con embolización de la arteria hepática derecha (AU)

To improve morbidity and mortality in patients with subcapsular liver hematoma, clinical suspicion, a rapid diagnosis and multidisciplinary treatment are fundamental. The treatment of this complication includes expectant management with clinical and radiological observation, embolization of the hepatic arteries, and surgical treatment if there is hemodynamic instability, persistent bleeding or increasing pain. We report a case of postpartum HELLP syndrome that was complicated by a subcapsular liver hematoma, successfully treated by embolization of the right hepatic artery (AU)

Ruptura aórtica abdominal espontánea por úlcera penetrante tratada mediante reparación endovascular / Treatment of spontaneous abdominal aortic rupture due to a penetrating ulcer by means of endovascular repair

Introducción. La úlcera penetrante aórtica se define como una lesión arterioesclerosa con ulceración de la íntima y media aórticas, con ruptura de la lámina elástica interna, que se localiza predominantemente en la aorta torácica; es infrecuente su localización en la aorta abdominal. La llegada de las técnicas endovasculares ha incrementado las posibilidades terapéuticas. Caso clínico. Varón de 77 años, que acudió a Urgencias por dolor abdominal y anemia progresiva. La tomografía computarizada mostraba una ruptura aórtica abdominal con fuga de contraste 1 cm por debajo del ostium de la arteria renal derecha, así como la presencia de pseudoaneurisma de 5 cm en el espacio subdiafragmático. Como tratamiento de urgencia se decidió la colocación de una endoprótesis aortouniilíaca con oclusor ilíaco derecho y bypass femorofemoral izquierda-derecha, excluyendo la arteria renal izquierda para el correcto sellado proximal. El paciente se estabilizó hemodinámicamente, pero falleció a los 97 días por fallo multiorgánico. La autopsia confirmó la correcta situación de la endoprótesis, sin fugas e integrada en la pared aórtica. Conclusión. La úlcera penetrante aórtica abdominal es una lesión potencialmente mortal por el elevado riesgo de ruptura. El tratamiento endoluminal constituye una opción terapéutica menos agresiva, que puede disminuir las tasas de morbimortalidad en pacientes de alto riesgo

Introduction. A penetrating aortic ulcer is defined as an arteriosclerotic lesion with ulceration of the aortic tunica intima and media, with rupture of the internal elastic lamina, which is predominantly located in the thoracic aorta; it is infrequently found in the abdominal aorta. The advent of endovascular techniques has brought with it an increase in the number of therapeutic possibilities available. Case report. A 77-year-old male, who visited the Emergency department with abdominal pain and progressive anaemia. A computerised tomography scan revealed the presence of a rupture of the abdominal aorta with contrast leak 1 cm below the ostium of the right renal artery, together with the presence of a 5-cm pseudoaneurysm in the subdiaphragmatic space. Emergency treatment consisted in placement of an aortouniiliac stent with right iliac occlusion and left-right femorofemoral bypass, with exclusion of the left renal artery in order to achieve proper proximal sealing. The patient became haemodynamically stable, but died at 97 days due to multiple organ failure; the autopsy confirmed correct location of the stent, with no leaks, and it was integrated within the wall of the aorta. Conclusions. Penetrating abdominal aortic ulcer is a potentially fatal lesion due to the high risk of rupture. Endoluminal treatment constitutes a less aggressive therapeutic option that can lower the morbidity and mortality rates in high risk patients
