RESUMO

Abstract The spleen is supplied by blood flow through the splenic artery and vein. The purpose of this communication is to report an ectopic spleen supplied only by reverse flow through the left gastro-omental vessels. A 14-year-old boy presented with pelvic splenomegaly supplied only by the left gastro-omental artery and veins connected to the inferior polar vessels, which were the only vessels communicating with the spleen. After detorsion of the spleen and splenopexy, the spleen returned to normal dimensions. The patient had uneventful follow-up. In conclusion, the left gastroepiploic vessels are able to maintain the entire spleen blood supply.


Resumo O baço é suprido pelo fluxo sanguíneo da artéria e veia esplênicas. O objetivo desta comunicação é apresentar um baço ectópico suprido apenas pelo fluxo sanguíneo reverso proveniente dos vasos gastromentais esquerdos. Um paciente de 14 anos apresentou esplenomegalia pélvica suprida apenas por artéria e veia gastromentais esquerdas, conectadas aos vasos polares inferiores, que eram os únicos presentes nesse baço. Após a distorção do baço e a esplenopexia, o baço voltou às dimensões normais. Não houve intercorrências no acompanhamento do paciente. Em conclusão, os vasos gastromentais esquerdos são capazes de suprir o fluxo sanguíneo de todo o baço.

RESUMO

The gastro-omental artery is one of the branches of the common hepatic artery. Alterations in the embryonic development of the ventral splanchnic arteries can cause marked variations. A rare variant of the right gastro-omental artery was observed during dissection of a 50-year-old male cadaver. The occurrence of this variant has not been reported in the specialized literature. This case of a different origin of the gastro-omental artery is described in detail in order to provide information that may contribute to upper abdominal surgeries.


La arteria gastro-omental es una de las ramas de la arteria hepática común. Las alteraciones en el desarrollo embrionario de las arterias ventrales pueden causar variaciones marcadas. Se observó una variante rara de la arteria gastro-omental derecha durante la disección de un cadáver de un hombre de 50 años de edad. La presencia de esta variante no se ha informado en la literatura especializada. Este caso de origen diferente de la arteria gastro-omental se describe detalladamente con el fin de proporcionar información que pueda contribuir a la cirugía abdominal superior.

RESUMO

BACKGROUND: Epiploic appendagitis is an atypical cause of abdominal pain whose knowledge could avoid diagnostic or treatment errors. Diagnosis has been performed with abdominal ultrasound or tomography with the only treatment being nonsteroidal anti-inflammatory drugs. OBJECTIVE: To analyze patients diagnosed in our hospital. METHODS: We performed a 4-year retrospective and descriptive study (March 2009-March 2013) of patients diagnosed with epiploic appendagitis in our hospital. RESULTS: Seventeen patients were included, 14 females and three males with a median age of 57 years. Symptom delay was 72 h. Abdominal pains were located in the left lower quadrant in 64.7% and right lower quadrant in 35.3% of patients. Blood test demonstrated leukocytes 6,300 (5,000-9,500), neutrophils 61.6% (57-65.8), and C reactive protein 1.5 (0.85-2.92). Diagnosis was confirmed with abdominal ultrasound or tomography in 88.2% and intraoperatively in 11.8%. CONCLUSIONS: Epiploic appendagitis was more frequent in women. Abdominal pain was located in the lower quadrant, more predominant in left than right. Blood tests were normal except for increased levels of C-reactive protein. Diagnosis was made mostly preoperatively due to imaging tests, avoiding unnecessary surgical intervention.


ANTECEDENTES: la apendagitis epiploica es una causa poco frecuente de dolor abdominal cuyo conocimiento podría evitar errores diagnósticos y terapéuticos. El diagnóstico suele establecerse mediante ecografía o tomografía abdominal; el tratamiento es sintomático, con antiinflamatorios. OBJETIVO: analizar los casos diagnosticados en nuestro centro. MATERIAL Y MÉTODOS: estudio retrospectivo y descriptivo de pacientes con diagnóstico de apendagitis epiploica durante 4 años (marzo 2009 a marzo 2013). RESULTADOS: se incluyeron 17 pacientes, 14 mujeres y 3 hombres, con una mediana de edad de 57 años. El periodo de latencia de los síntomas fue 72 horas. En 64.7% de los pacientes el dolor abdominal se localizó en el cuadrante inferior izquierdo y en 35.3% en el derecho. Laboratorio: leucocitos 6,300 (5,000-9,500), neutrófilos 61.6% (57- 65.8), proteína C reactiva 1.5 (0.85-2.92). El diagnóstico se confirmó mediante ecografía o tomografía abdominal en 88.2%, e intraoperatorio en 11.8%. CONCLUSIONES: la apendagitis epiploica fue más frecuente en mujeres. La clínica fue dolor abdominal en los cuadrantes inferiores, más frecuente en el lado izquierdo, con RESULTADOS de laboratorio normales, excepto la elevación de la proteína C reactiva. En la mayoría de los casos el diagnóstico se estableció preoperatoriomente, gracias al uso de pruebas radiológicas que evitó las intervenciones quirúrgicas innecesarias.

RESUMO

BACKGROUND: Strangulated inguinal hernia (SIH) has an overall prevalence of 1.3% in adults, affecting mainly senilepatients, with a high incidence of morbidity and mortality. There are more than 13 different surgical techniques for treatment,but none has proven to be more effective than the others. METHODS: The present observational, longitudinal and prospective study carried out at Hospital General, Centro MedicoLa Raza in Mexico City proposes a new surgical technique to treat SIH. Between December 2000 and August 2010,43 adult patients with SIH were consecutively subjected to preperitoneal mesh repair and exploratory laparotomy (PPMRand ELAP), a personal modification by the author to the Stoppa-Rives technique. Several variables were studied. RESULTS: There was zero mortality. There were no cases of inguinal recurrence or reintervention. One patient developeda granuloma at the surgical site. There were three cases of superficial wound infection, six cases of inguinoscrotal seroma,and one case of incisional hernia. DISCUSSION: There is no international consensus on the treatment of SIH although it is interesting to analyze the studiespublished during the last two decades and to observe the results. Studies that propose a preperitoneal approach withmesh demonstrate the best results by reducing morbidity and mortality. CONCLUSIONS: Preperitoneal mesh repair and exploratory laparotomy reduce the rate of morbidity and mortality in thetreatment of SIH. Inguinal hernias must be repaired at the time of diagnosis to avoid strangulation.

RESUMO

CONTEXT: The omentoenteropexy technique was developed as an alternative method for intestinal neovascularization, due to the angiogenic properties of factors from the omentum. OBJECTIVES: This study investigated changes in intestinal villi heights and crypts depths due to surgical techniques: seromiotomy with and without omentoenteropexy. METHOD: Thirty rats were operated on, after being divided into three groups, namely GI, GII and GIII with 10 rats each. In the GI rats were submitted to omentoenteropexy; rats in GII were submitted only to a seromiotomy, and in the GIII only laparotomy. Sixty days after the first surgery, the animals were sacrificed and a segment of intestine was removed for histology using Masson's trichrome technique and morphometric study of intestinal mucosa. RESULTS: The histological findings showed that seromiotomy with or without omentoenteropexy increased the length of intestinal villi when compared with GIII (only laparotomy) (analysis of variance: P = 0.0068; GI 38.88 ± 4.17; GII 39.41± 6.33; GIII 31.85 ± 5.56; GI = GII P>0.05; GII>GIII P<0.05; GI>GIII P<0.001). CONCLUSION: No differences were demonstrated in relation to crypt depths between the groups (P = 0.60). Ongoing studies are being set forth by our group to add more data on the role of omentopexy as a tool to promote neovascularization and intestinal mucosal growth.
