Infarto esplénico como complicación de gastrectomía vertical laparoscópica. Reporte de caso / Splenic infarction as a complication of laparoscopic vertical gastrectomy. Case report

La gastrectomía vertical laparoscópica es actualmente la cirugía bariátrica más empleada a nivel mundial. Aunque es un procedimiento seguro y efectivo pueden ocurrir complicaciones mayores. En el presente trabajo reportamos el caso de un infarto y absceso esplénico como una rara complicación de esta técnica, que requirió finalmente de esplenectomía como tratamiento definitivo. Caso clínico: Mujer de 22 años con obesidad grado I, a quien se le practicó gastrectomía vertical laparoscópica con buena evolución intrahospitalaria y egreso a las 48 horas. Al 4to día posoperatorio consultó por fiebre, dolor abdominal, taquipnea y taquicardia. Mediante tomografía computada de abdomen se diagnosticó infarto esplénico parcial. Recibió tratamiento médico con remisión inicial de los síntomas, los cuales reaparecieron a la 3era semana. Se reinició el tratamiento médico, esta vez sin respuesta, y con evolución al absceso esplénico. Se decidió esplenectomía como tratamiento definitivo logrando la recuperación completa de la paciente. Conclusión: El infarto esplénico es una complicación infrecuente de la gastrectomía vertical. Su tratamiento inicial es médico, reservando la esplenectomía para los casos que no responden(AU)

Laparoscopic sleeve gastrectomy is currently the most performed bariatric surgery worldwide. Although it is an effective and safe procedure major complications can occur. In the present manuscript we report a case of splenic infarct and abscess as a rare complication of laparoscopic sleeve gastrectomy, finally requiring a splenectomy as a definitive treatment. Case report: A 22 years old woman with grade I obesity underwent laparoscopic sleeve gastrectomy with good hospital evolution and 48 hours discharge. On the 4th postoperative day she return because fever, abdominal pain, tachypnea and tachycardia. By means of a computed tomography a splenic infarct was diagnosed. She received medical treatment with initial remission of symptoms, which reappear at the third week. Medical treatment was restarted, this time without success, and with progression to splenic abscess. We decided a splenectomy as definitive treatment achieving a complete patient recovery. Conclusion: Splenic infarction is a rare complication after sleeve gastrectomy. The treatment is non surgical, reserving the splenectomy for the non responded cases(AU)

Bazo errante gigante con torsión del pedículo e infarto esplénico: reporte de un caso / Giant Wandering Spleen with torsion of the pedicle and splenic infarction: a case report

INTRODUCCIÓN: El bazo errante, es una entidad clínica poco común. Su espectro clínico varía desde enfermedad asintomática hasta complicaciones asociadas y su manejo es predominantemente quirúrgico. CASO CLÍNICO: Hombre, con cuadro clínico de dolor y masa abdominal palpable, con hallazgos tomográficos sugestivos de patología con asiento en retroperitoneo, con obstrucción intestinal secundaria; por laparotomía se identifica de forma incidental bazo ectópico solo fijado a través de pedículo vascular torsionado y signos de hipertensión portal, realizándose esplenectomía. CONCLUSIONES: La torsión esplénica es la complicación más frecuente del bazo errante, una entidad bastante rara con muy pocos casos publicados en Colombia.

BACKGROUND: The wandering spleen is an uncommon clinical entity. Its clinical spectrum varies from asymptomatic disease to associated complications and its management is predominantly by surgery. CLINICAL CASE: Man with clinical picture of pain and palpable abdominal mass, with tomographic findings suggestive of pathology with retroperitoneal seating, with secondary intestinal obstruction; by laparotomy incidentally, an ectopic spleen is identified, only fixed through a torsioned vascular pedicle and signs of portal hypertension, performing splenectomy. CONCLUSIONS: Splenic torsion is the most frequent complication of the errant spleen, a very rare entity with very few cases published in Colombia.

Rol de la tomografía computada de abdomen en la evaluación de gastrectomía en manga laparoscópica y sus complicaciones / Role of abdominal computed tomography in the evaluation of laparoscopic sleeve gastrectomy technique and its complications

Bariatric surgery has developed considerably over recent years due to the progressive increase in obesity worldwide. The laparoscopic sleeve gastrectomy is a new restrictive technique, with promising initial outcomes. CT images play an important role in postoperative evaluation as well as in complication management in patients undergoing this surgical technique. Here we review the role of abdominal computed tomography in the study of potential complications.

La cirugía bariátrica se ha desarrollado considerablemente en el último tiempo como consecuencia del aumento progresivo de la obesidad a nivel mundial. La gastrectomía en manga laparoscópica es una técnica restrictiva nueva, con resultados iniciales prometedores. Las imágenes juegan un rol importante en la evaluación postoperatoria por lo que es imprescindible conocer los cambios anatómicos normales y las principales complicaciones de esta técnica. En este trabajo revisamos el rol de la tomografía computada de abdomen en el estudio de posibles complicaciones.

Renal and Splenic Micro-Infarctions Following Bronchial Artery Embolization with Tris-Acryl Microspheres

A bronchial artery embolization (BAE) is an important therapeutic method used to control acute and chronic hemoptysis. We report a case of multiple micro-infarcts involving both the kidneys and spleen, following a BAE with 500-700 micrometer crossed-linked tris-acryl microspheres (Embospheres) in a patient with bronchial artery pulmonary vein shunts. The superior penetration characteristics of the microspheres may have resulted in the greater tendency to cross the bronchial artery pulmonary vein shunts, which subsequently caused the systemic infarcts in our patient. We propose the use of larger sized microspheres (700-900 micrometer), which may aid in avoiding this complication.

Splenic complications in malaria: a case series.

Splenic complications in malaria may be either simple asymptomatic enlargement or serious conditions, such as splenic infarction, rupture, hematoma or abscess, which can be fatal. Only a few cases have been reported in the literature since 1960. The true incidence of splenic complications is not known because of underdiagnosis and underreporting. We report here four cases which were successfully treated conservatively.

Celiac Artery Thrombosis and Splenic Infarction in a Patient with Protein S Deficiency / 대한소화기학회지

Protein S deficiency is a rare blood disorder associated with an increased risk of thrombosis. Only a few cases of arterial thrombosis of digestive tract have been noted. We report a case of celiac arterial thrombosis and splenic infarction in 46-year-old male with protein S deficiency. Abdominal computed tomography and angiography revealed thrombotic obstruction of the proximal celiac and common hepatic artery with splenic infarction. His total and free antigen of protein S were normal, however, the activity of protein S was low. Percutaneous transluminal angioplasty was performed to revascularise celiac and common hepatic artery.

Viabilidade do baço de ratos após a ligadura dos vasos esplênicos: efeito do tratamento com oxigênio hiperbárico / Viability of the spleen in rats after ligation of the splenic vessels: effects of hyperbaric oxygen therapy

OBJETIVO: Verificar o efeito da ligadura dos vasos esplênicos principais no baço de ratos e a influência do tratamento com o oxigênio hiperbárico após a ligadura. MÉTODOS: Foram operados 69 ratos Wistar, machos, de 285g a 375 g. Os animais foram divididos aleatoriamente em três grupos: grupo 1: quatro ratos, simulação; grupo 2: 34 ratos, ligadura simultânea da artéria e veia esplênica; grupo 3: 31 ratos, ligadura da artéria e veia esplênica seguida de oxigenioterapia hiperbárica no pós-operatório por 11 dias, sendo mortos no 12° dia. O baço era retirado e incluído em parafina para estudo microscópico. RESULTADOS: O baço era normal em 8,82 por cento e 45,16 por cento, respectivamente, no grupo que sofreu a ligadura vascular sem ou com oxigenioterapia hiperbárica (p= 0,01). O percentual de massa viável do tecido esplênico nos baços que infartaram em relação ao percentual da massa corporal dos animais não diferiu entre os grupos 2 e 3. O aspecto histopatológico mostrou arquitetura preservada na porção não infartada nos dois grupos e neoformação conjuntivo-vascular cicatricial mais acentuada no grupo que recebeu oxigênio hiperbárico. CONCLUSÕES: O tratamento com oxigênio hiperbárico, a partir do pós-operatório imediato, após a ligadura simultânea da artéria e da veia esplênicas, reduziu significativamente a freqüência dos infartos, mas não alterou o percentual de massa viável dos baços, quando o infarto ocorreu, e acelerou o processo de cicatrização, com aumento da proliferação de fibroblastos e da neoformação vascular.

Multiple systemic emboli complicating the course of a patient with an atrial septal defect, an atrial septal aneurysm and an endocardial right atrial pacemaker lead

We describe an adult patient with a large atrial septal defect, an atrial septal aneurysm and thrombus formation on a transvenous right atrial pacing lead. Because of right-to-left shunting through the atrial septal defect, she developed multiple systemic emboli to the spleen and left kidney (with infarcts), to the left leg, and probably to the brain as a cerebrovascular accident. The fundamental guiding principle of avoiding endocardial pacing leads in patients with congenital intracardiac communications, was violated in this patient, leading to serious dire consequences and complications.

Hypertension in sickle cell disease.

We report a young male with sickle cell trait who developed severe hypertension and splenic infarction soon after travel to a high altitude. Hypertension persisted for three days after a diagnostic laparotomy. His blood pressure then continued to be normal over the next one and a half years. Red cell sludging in the small vessels of the kidney possibly activated the renin angiotensin system.

Histiocytic medullary reticulosis radiologic diagnosis of splenic infarction: a case report

A case of histiocytic medullary reticulosis with splenic infaraction from a 23-year-old male is presented. Radiologic findings on selective spleen scintigraphy and abdominal CT are described. Selective spleen scintigraphy showed huge, multilobulated spleen with numerous photon-deficient areas in it and peripherally. Abdominal CT showed large peripheral band-like low density and infiltrative lesion in spleen with accompanying intraabdominal lymphadenopathy. Histoligical features were consistent with HMR in spleen and liver specimens.
