ABSTRACT
Objective: To investigate the factors influencing small intestinal ischemia in elderly patients with incarcerated hernia. Methods: The clinical data of 105 elderly patients admitted for surgical procedures of incarcerated hernia at Department of General Surgery, Huadong Hospital between January 2014 and December 2021 were retrospectively analyzed. There were 60 males and 45 females, aged (86.1±4.3) years (range: 80 to 96 years). They were divided into normal group (n=55) and ischemic group (n=50) according to intraoperative intestinal canal condition. The t test, χ2 test and Fisher's exact probability method were used for the univariate analysis of the factors that influence intestinal ischemia in patients, and Logistic regression was used for multifactorial analysis. Results: In all patients, 18 patients (17.1%) had irreversible intestinal ischemia with bowel resection. Six patients died within 30 days, 3 cases from severe abdominal infection, 2 cases from postoperative exacerbation of underlying cardiac disease, and 1 case from respiratory failure due to severe pulmonary infection. The results of the univariate analysis showed that there were differences in gender, history of intussusception, duration of previous hernia, white blood cell count, neutrophil percentage, C-reactive protein, type of incarcerated hernia, and preoperative intestinal obstruction between the two groups (all P<0.05). The Logistic regression results showed that the short time to the previous hernia (OR=0.892, 95%CI 0.872 to 0.962, P=0.003), high C-reactive protein (OR=1.022, 95%CI 1.007 to 1.037, P=0.003), non-indirect incarcerated hernia (OR=10.571, 95%CI 3.711 to 30.114, P<0.01) and preoperative intestinal obstruction (OR=6.438, 95%CI 1.762 to 23.522, P=0.005) were independent risk factors for the development of intestinal ischemia in elderly patients with incarcerated hernia. Conclusions: The short duration of the previous hernia, the high values of C-reactive proteins, the non-indirect incarcerated hernia, and the preoperative bowel obstruction are influencing factors for bowel ischemia in elderly patients with incarcerated hernia. A timely operation is necessary to reduce the incidence of intestinal necrosis and improve the prognosis.

La isquemia mesentérica aguda (IMA) es consecuencia de la oclusión de la arteria mesentérica superior (AMS) por trombosis o embolia, es considerada como la más letal del síndrome de abdomen agudo. Se presenta el caso de paciente femenina de 69 años con clínica difusa y confirmación diagnóstica radiológica, El objetivo de este caso clínico es proporcionar una revisión bibliográfica actual del tema y facilitar la adecuada actuación ante este problema de salud de amplio compromiso sistémico, de aparición no tan infrecuente.
Acute mesenteric ischemia (IMA) is a consequence of occlusion of the superior mesenteric artery (AMS) by thrombosis or embolism, it is considered the most lethal of acute abdomen syndrome. The case of a 69-year-old female patient with diffuse clinic and radiological diagnostic confirmation is presented. The objective of this clinical case is to provide a current bibliographic review of the topic and facilitate adequate action in the face of this health problem with a broad systemic commitment, with no appearance. so infrequent.

Abstract Purpose: To develop an experimental model of intestinal ischemia and obstruction followed by surgical resection of the damaged segment and reestablishment of intestinal transit, looking at bacterial translocation and survival. Methods: After anesthesia, Wistar rats was subject to laparotomy, intestinal ischemia and obstruction through an ileal ligature 1.5cm of ileum cecal valve; and the mesenteric vessels that irrigate upstream of the obstruction site to approximately 7 to 10 cm were ligated. Abdominal wall was closed. Three, six or twenty-four hours after, rats were subject to enterectomy followed by an end to end anastomosis. After 24h, mesenteric lymph nodes, liver, spleen and lung tissues were surgically removed. It was studied survival rate and bacterial translocation. GraphPadPrism statistical program was used. Results: Animals with intestinal ischemia and obstruction for 3 hours survived 24 hours after enterectomy; 6hx24h: survival was 70% at 24 hours; 24hx24h: survival was 70% and 40%, before and after enterectomy, respectively. Culture of tissues showed positivity on the 6hx24h and negativity on the 3hx24h. Conclusion: The model that best approached the clinic was the one of 6x24h of ischemia and intestinal obstruction, in which it was observed bacterial translocation and low mortality rate.

Background: Chronic mesenteric ischemia is observed in older people and is often due to atherosclerosis. Radiotherapy is an important risk factor for atherosclerosis. Aim: To report our experience with chronic mesenteric ischemia secondary to retroperitoneal radiotherapy. Material and methods: Review of medical records of four male patients aged 39 to 65 years, treated for chronic mesenteric ischemia secondary to para-aortic radiotherapy between 1993 and 2011. Results: All of them had the classic symptoms of ischemia characterized by post prandial abdominal pain and weight loss. One had also isolated diarrhea episodes. Revascularization was achieved with open or endovascular surgery, with good results during a follow up period ranging from two to 20 years. Conclusions: Surgical revascularization is a good treatment for chronic mesenteric ischemia secondary to radiotherapy.
Introducción: La insuficiencia mesentérica crónica es un diagnóstico infrecuente, generalmente secundario a enfermedad aterosclerótica, siendo considerada una enfermedad de pacientes añosos. Se sabe que la radioterapia es un factor de riesgo importante para aterosclerosis. Describimos nuestra experiencia en el manejo de la isquemia mesentérica crónica secundaria a radioterapia retroperitoneal. Materiales y métodos: Análisis retrospectivo de las fichas clínicas de los pacientes tratados en nuestro centro por insuficiencia mesentérica crónica posterior a radioterapia del territorio para-aórtico entre 1993 y 2011. Resultados: Un total de 4 pacientes de sexo masculino fueron identificados. Edad promedio: 49 +/- 12 años (rango 39-65). Todos presentaron los síntomas clásicos de insuficiencia mesentérica caracterizados por dolor abdominal postprandial y baja de peso. Uno de ellos además tenía episodios repetidos de diarrea. La revascularización mesentérica se obtuvo mediante cirugía abierta o endovascular con excelentes resultados a corto y largo plazo con un seguimiento promedio de 9,3 años (rango 2-20). Discusión: El curso acelerado de la aterosclerosis posterior a radioterapia se ha descrito en múltiples territorios vasculares. Síntomas de insuficiencia mesentérica crónica pueden ser malinterpretados en estos pacientes debido a su similitud con los síntomas observados en la ileitis actínica. Un diagnóstico y tratamiento oportuno son críticos para evitar complicaciones mayores y deterioro de calidad de vida de estos pacientes. Conclusión: La insuficiencia mesentérica crónica inducida por radioterapia es una condición infrecuente. El manejo con cirugía abierta o endovascular son seguras y otorgan resolución sintomática a largo plazo.
