ABSTRACT

Resumen Introducción: El síndrome de Wilkie es una causa poco frecuente de obstrucción del tracto digestivo superior, se caracteriza por una disminución del ángulo aorto-mesentérico que resulta en compresión de la tercera porción del duodeno que produce síntomas obstructivos altos. Caso Clínico: Presentamos el caso de una mujer de 64 años, con historia de dolor abdominal, pirosis, saciedad precoz e intolerancia a la vía oral, en quien los estudios iniciales mostraron esofagitis, pero en quien los síntomas no mejoraron con el tratamiento clásico para enfermedad ácido péptica y en quien estudios imagenológicos adicionales sugerían el síndrome de Wilkie como causa de los síntomas. Discusión y Conclusión: Se trata de una patología que debe conocerse y considerar en paciente con historia de pérdida de peso, marcada intolerancia a la vía oral y falta de respuesta al manejo.


Introduction: Wilkie syndrome is a rare cause of upper gastrointestinal tract obstruction, it is characterized by a decrease in the aorto-mesenteric angle that results in a compression of the third portion of the duodenum causing high obstructive symptoms. Case Report: We present the case of a 64-year-old woman, with a history of abdominal pain, heartburn, early satiety, and intolerance to the oral route, in whom initial studies showed esophagitis, but in whom symptoms did not improve with the classic treatment for peptic acid disease, additional imaging studies suggested Wilkie syndrome. Discussion and Conclusión: It is a pathology that must be known and suspected in patients with a history of weight loss, marked intolerance to oral intake, and lack of treatment response.

ABSTRACT

RESUMEN El dispositivo intrauterino (DIU) es un método anticonceptivo muy popular, eficaz y seguro. Aunque posee complicaciones bien descritas como es la migración, la que puede ser a otros órganos dentro de la cavidad peritoneal. La fístula uteroyeyunal es un evento clínico poco frecuente, pero de gran repercusión si no es diagnosticada y tratada. Se presenta el caso de una paciente usuaria de DIU, el que migra a cavidad abdominal, con posterior formación de fístula uteroyeyunal.


ABSTRACT The intrauterine device is a popular, efficient and safe contraceptive. Although it has some well described complications, such as migration, which may be to the different organs inside of the peritoneal cavity. The uterus-jejunal fistula is a rare clinical event, but with great repercussion if it is not well assessed and treated properly. We present the clinical case of a patient with a migrated intrauterine device and a fistula uterus-jejunal formation.

ABSTRACT

Las anormalidades vasculares del tracto gastrointestinal son una causa común de sangrado digestivo. La mayoría se localizan al alcance de la endoscopía digestiva alta y/o colonoscopía, una vez descartado ello, obliga a considerar al intestino delgado como causa de la hemorragia. El manejo exitoso de una hemorragia digestiva depende principalmente de la localización oportuna de la fuente del sangrado, sin embargo esta tarea puede ser difícil, cuando la causa no está al alcance de los métodos convencionales. Presentamos el caso de un paciente varón de 21 años cuyo diagnóstico fue una flebectasia yeyunal sangrante, luego de una cuidadosa evaluación de los hallazgos de la cápsula endoscópica y laparoscopía.


Vascular abnormalities of the gastrointestinal tract are a common cause of gastrointestinal bleeding. Most of them are located within the reach of the upper endoscopy or colonoscopy, although once discarded, it forces to consider small bowel as the source of bleeding. The successful management of a gastrointestinal bleeding depends mainly on the timely location of the source of bleeding. Nevertheless this task can be difficult when the cause is not within the reach of conventional methods. We present a case of a 21 year-old men in which the diagnosis of bleeding yeyunal phlebectasia was made by the findings of the capsule endoscopy and laparoscopy.

ABSTRACT

Objetivo: Realizar un análisis retrospectivo de una serie de casos de diverticulitis yeyuno-ileal complicadas tratadas quirúrgicamente en nuestro servicio durante el periodo comprendido entre los años 2002 al 2015. Materiales y métodos: Se trató quirúrgicamente 12 casos de diverticulosis yeyuno-ileal complicadas, 7 mujeres y 5 varones. La edad media fue 76 años. La presentación clínica en todos los casos fue dolor abdominal agudo, uno de ellos con hemorragia digestiva. Todos presentaron leucocitosis, neutrofilia y aumento de reactantes de fase aguda. A todos los pacientes se les realizó TAC abdominal urgente. Resultados: En 11 casos hubo congruencia entre estudio de imagen y hallazgos quirúrgicos. La localización de los divertículos fue yeyuno (9) e íleon (3). Siempre se realizó laparotomía exploradora urgente encontrándose perforación diverticular con peritonitis (7 casos), perforación diverticular con absceso (4 casos) y en un caso un área isquémica con perforación diverticular tras embolización. Se realizó siempre resección intestinal y anastomosis. En ningún caso se conocía previamente el diagnóstico de diverticulosis yeyuno-ileal. Nuestras complicaciones fueron: Clavien I (2), Clavien IIIa (1), Clavien IVb (1), Clavien V (1). Conclusiones: La diverticulitis yetuno-ileal es una entidad infrecuente, suele ser la forma de debut de una enfermedad diverticular no conocida previamente. El TAC abdominal es de gran utilidad diagnóstica. La resección del segmento afecto es el tratamiento de elección


Objective: To perform a retrospective analysis of a series of complicated JID (jejunoileal diverticulitis) cases surgically treated in our service during the period from 2002 to 2015. Materials and methods: We treated 12 cases of jejunoileal complicated diverticulosis. 7 women and 5 men. The mean age was 76 years. The clinical presentation in all cases was acute abdominal pain, one with gastrointestinal bleeding. All cases had leukocytosis, neutrophilia and increased acute phase reactants. All patients underwent emergency abdominal CT. Results: In 11 cases, there was consistency between imaging studies and surgical findings. Diverticula were located: jejunum (9) and ileum (3). Urgent exploratory laparotomy was always done and findings were: diverticular perforation with peritonitis (7 cases), diverticular perforation with abscess (4 cases) and in one case an ischemic area with diverticular perforation after embolization. Intestinal resection and anastomosis was performed in all cases. There were no patients, in which the diagnosis of diverticulosis jejunoileal was previously known. Complications were: Clavien I (2), Clavien IIIa (1), Clavien IVb (1), Clavien V (1). Conclusions: Jejunoileal diverticulitis is a rare entity, usually the first sign of onset of diverticular disease not previously known. Abdominal CT is of great diagnostic value. Resection of the affected segment is the treatment of choice

ABSTRACT

Diverticular disease of the small intestine is rare, especially when it is located in the jejunum. It is generally asymptomatic, but in some patients it may have complications such as acute diverticulitis with peritonitis, gastrointestinal bleeding or obstruction. In such cases, the recommended treatment is surgery. We report a 77-year-old patient with ileal Crohn’s disease with a long-standing inflammatory phenotype, who developed acute diverticulitis of the jejunum presenting a severe septic shock and secondary multiple-organ failure. It resolved with medical treatment and prolonged antibiotic therapy.

ABSTRACT

Jejunoileal diverticulosis is an uncommon and underdiagnosed condition. Most patients are asymptomatic and require no specific treatment. A few patients, however, present life-threatening complications that may require surgical intervention. The purpose of this report is to illustrate a case of jejunoileal diverticulosis manifested as an acute abdomen.


A doença diverticular do intestino delgado é uma entidade incomum e pouco diagnosticada. A maioria dos casos não apresenta sintomas e não necessita de tratamento específico. Alguns pacientes, no entanto, podem evoluir com complicações da doença e necessitar de tratamento cirúrgico. O objetivo deste relato é ilustrar um caso de diverticulose jejunal que evoluiu para um quadro de abdome agudo.

ABSTRACT

Una paciente de 83 años, con antecedentes de hipertensión arterial y diabetes mellitus bajo tratamiento, fue ingresó al hospital por un cuadro de sangrado digestivo, caracterizado por melenas y rectorragia, con compromiso hemodinámico. La endoscopia alta y colonoscopia no encontraron el origen del sangrado, por lo cual se empleó una cápsula endoscó- pica. El examen reveló a nivel de yeyuno medio y distal la presencia de sangrado activo proveniente de varios vasos pequeños y tortuosos, ligeramente elevados de diferentes tamaños, lesiones compatibles con múltiples angiodisplasias (foto 1 y 2). Además, a las dos horas del estudio, se visualizó imagen de una lesión ulcerada comprometiendo la luz yeyunal y cubierta con fbrina, sin sangrado activo, que como consecuencia generaba una estenosis luminal, por lo que la cápsula permaneció a este nivel por el lapso de 5 horas (foto 3). La paciente evolucionó con deterioro de su condición médica, fue ingresada a la Unidad de Terapia Intensiva y posteriormente falleció por una falla multiorgánica.


An 83-year-old patient with a history of hypertension arterial and diabetes mellitus under treatment, was admitted to hospital for a picture of digestive bleeding, characterized by mane and rectorragia, with hemodynamic commitment. The high endoscopy and colonoscopy did not find the origin of bleeding, whereby an endoscopic capsule was used pica. The examination revealed at the level of middle and distal jejunum the presence of active bleeding from several vessels small and tortuous, slightly elevated from different sizes, lesions compatible with multiple angiodysplasias (photo 1 and 2). In addition, two hours after the study, it was visualized image of an ulcerated lesion compromising jejunal light and covered with fbrine, without active bleeding, which as consequence generated a luminal stenosis, so the capsule remained at this level for 5 hours (photo 3). The patient evolved with deterioration of her medical condition, she was admitted to the Intensive Care Unit and He subsequently died of a multi-organ failure.

ABSTRACT

Jejunal diverticula have a prevalence of approximately 1% in the general population. Perforation of jejunal diverticulum is a rare. Clinically this diagnosis may be easily confused with other causes of an acute abdomen. In the article, we discuss a 74-year-old man with a 2-day history of constipation and left-sided abdominal pain. The day before admission he developed an abrupt exacerbation his symptoms with pain localized to periumbilical and left lower quadrant. An abdominal computed tomography scan revealed soft tissue stranding within the left upper quadrant, bilateral plural effusions, larger on the left, an opacity with the right and left pulmonary lobes and polypoid lesion with in stomach. Physical examination revealed left upper quadrant fullness. An emergency laparotomy was carried out. This revealed multiple jejunal diverticula, one of which had perforated 40 centimeters distal to the ligament of Treitz

ABSTRACT

Cytomegalovirus (CMV) infections are usually diagnosed in immunocompromised patients. A 74-year-old male without any significant medical history visited our center because of abdominal pain and diarrhea which began about a month ago. Abdominal computed tomography revealed segmental enhanced bowel wall thickening on jejunum and single-balloon enteroscopy showed multiple geographic shaped ulcerations covered with exudates on proximal jejunum. Biopsy samples taken during endoscopic examination demonstrated necrotic fibrinopurulent tissue debris and benign ulcer. Nested-PCR analysis of CMV DNA from jejunal tissue was positive. The patient was finally diagnosed with CMV jejunitis and was treated by intravenous ganciclovir for 14 days after which, abdominal pain and diarrhea improved. Our case shows that CMV jejunitis can occur in an immunocompetent adult as multiple jejunal ulcers which can be diagnosed using a single-balloon enteroscope.

ABSTRACT

While esophagogastric varices are common manifestations of portal hypertension, variceal bleeding from the jejunum is a rare complication of liver cirrhosis. In addition, ectopic variceal bleeding occurs in the duodenum and at sites of previous bowel surgery in most cases, including of stomas. We report a case of obscure overt gastrointestinal bleeding from jejunal varices in a 55-year-old woman who had not previously undergone abdominal surgery, who had liver cirrhosis induced by the hepatitis C virus. Emergency endoscopy revealed the presence of esophageal varices without stigmata of recent bleeding, and no bleeding focus was found at colonoscopy. She continued to produce recurrent melena with hematochezia and received up to 21 units of packed red blood cells. CT angiography revealed the presence of jejunal varices, but no active bleeding was found. Capsule endoscopy revealed fresh blood in the jejunum. The patient submitted to embolization of the jejunal varices via the portal vein, after which she had a stable hemoglobin level and no recurrence of the melena. This is a case of variceal bleeding from the jejunum in a liver cirrhosis patient without a prior history of abdominal surgery.

ABSTRACT

The Dieulafoy lesion is a rare cause of severe gastrointestinal hemorrhage. Although it may occur anywhere in the gastrointestinal tract, the lesion is most commonly located in the stomach, and the small bowel is an extremely uncommon site. Since Dieulafoy lesion in the small bowel is difficult to access by endoscopy, it seems impossible to diagnose and treat by initial endoscopy unlike the lesions in stomach. We experienced a case of Dieulafoy lesion of jejunum with massive hemorrhage in 54-year-old male. Active jejunal bleeding was shown by computed tomography scan and mesenteric angiography. Partial resection of the jejunum was performed. Final pathologic finding revealed Dieulafoy lesion of the jejunum.

ABSTRACT

Hookworm infection is a relatively common cause of anemia in endemic areas. The most common hookworm species are Ancylostoma duodenale and Necator americanus. In this report we present a case of overt gastrointestinal bleeding because of hookworm infection. Capsule endoscopy revealed many hookworms in the lumen of proximal jejunum where active bleeding was seen. The patient was successfully treated with Albendazole.

ABSTRACT

In contrast to diverticulosis of the colon, jejunal diverticulosis is a rare entity that often becomes clinically relevant only after exacerbations occur. The variety of symptoms and low incidence make this disease a difficult differential diagnosis. Data from all patients who were treated in our surgical department for complicated jejunal diverticulitis, that is, gastrointestinal hemorrhage or a diverticula perforation were collected prospectively over a 6-year period [January 2004 to January 2010] and analyzed retrospectively. The median age among the 9 patients was 82 years [range: 54-87]. Except for 2 cases [elective operation for a status postjejunal peridiverticulitis and a re-perforation of a diverticula in a patient s/p segment resection with free perforation], the diagnosis could only be confirmed with an exploratory laparotomy. Perforation was observed in 5 patients, one of which was a retroperitoneal perforation. The retroperitoneal perforation was associated with transanal hemorrhage. Hemodynamically relevant transanal hemorrhage requiring transfusion were the reason for an exploratory laparotomy in 2 further cases. In one patient, the hemorrhage was the result of a systemic vasculitis with resultant gastrointestinal involvement. A singular jejunal diverticulum caused an adhesive ileus in one patient. The extent of jejunal diverticulosis varied between a singular diverticulum to complete jejunal involvement. A tangential, transverse excision of the diverticulum was carried out in 3 patients. The indication for segment resection was made in the case of a perforation with associated peritonitis [n=4] as well as the presence of 5 or more diverticula [n=2]. Histological analysis revealed chronic pandiverticulitis in all patients. Median operating time amounted to 142 minutes [range: 65-210] and the median in-hospital stay was 12 days [range: 5-45]. Lethality was 0%. Major complications included secondary wound closure after s/p repeated lavage and bilateral pleural effusions in one case. Signs of malabsorption as the result of a short bowel syndrome were not observed. Minor complications included protracted intestinal atony in 2 cases and pneumonia in one case. Median follow-up was 6 months [range: 1-18]. Complicated jejunal diverticulitis often remains elusive preoperatively due to its unspecific clinical presentation. A definitive diagnosis can often only be made intraoperatively. The resection of all diverticula and/or the complete diverticula-laden segment is the goal in chronic cases. The operative approach chosen [tangential, transverse excision vs segment resection] should be based on the extent of the jejunal diverticulosis as well as the intraoperative findings

ABSTRACT

Stercoral perforation of the colon is an unusual pathological condition with fewer than 150 cases reported in the literature to date. We present a case of stercoral colonic perforation mimicking upper gastrointestinal perforation, which was diagnosed by computed tomography preoperatively. However, at laparotomy, stercoral colonic diverticulum perforation with jejunal diverticulitis became the most appropriate diagnosis.

ABSTRACT

There are various etiologies of duodenojejunitis such as Henoch-Schonlein purpura (H-S purpura), vasculitis, Crohn's disease, celiac sprue, ischemia, lymphoma, Zollinger-Ellison syndrome, bacteria or parasite infection, radiation, drug induced jejunitis, eosinophilic jejunitis, and toxins. A 31-year-old man presented with left upper quadrant pain. He did not have febrile sense, hematochezia, melena, diarrhea, arthralgia and hematuria. He had neither drug history nor traveling history. Esophagogastroduodenoscopy showed diffuse mucosal erythema and segmental hemorrhagic erosions on the distal area to the descending portion of the duodenum and proximal jejunum, which were commonly observed in the gastrointestinal involvement of H-S purpura. However, he showed no skin lesions, joint and urologic problems until the discharge. Autoimmune markers such as antinuclear antibody and antineutrophil cytoplasmic antibody were negative. Celiac and mesenteric angiogram showed no vascular abnormality. After the administration of oral prednisolone 40 mg daily for therapeutic trial, abdominal pain and endoscopic lesions were improved. He experienced relapses of same episode without skin lesions 16 times during follow-up of 8 years, which were also treated with prednisolone. The abdominal computed tomography during the follow-up also showed no significant finding. We report a case of primary recurrent duodenojejunitis similar to the gastrointestinal involvement of H-S purpura without purpura.

ABSTRACT

O objetivo do presente estudo foi analisar as alterações ultraestruturais nas vilosidades do jejuno de seis equinos submetidos à distensão intraluminal com solução salina. A pressão intraluminal foi mantida em 25cm de água durante duas horas. As amostras de mucosa intestinal colhidas às: zero hora; duas horas de distensão; e duas horas e 12h de descompressão foram analisadas por meio de microscopia eletrônica de varredura. Avaliaram-se a área e o perímetro das vilosidades e sua densidade, usando-se um programa computacional de análise de imagens (Image J). A distensão luminal promoveu aumentos da área e do perímetro das vilosidades intestinais. Essa alteração ultraestrutural ocorreu somente 12h após a descompressão e considerou-se que a provável causa seria o edema promovido por aumento da permeabilidade vascular decorrente de um processo de isquemia e reperfusão da mucosa intestinal. Concluiu-se que a distensão intraluminal do jejuno equino promoveu, tardiamente, aumento das dimensões das vilosidades intestinais.


The ultra-structural alterations in the equine jejune villi caused by intraluminal distension were analyzed. Six animals had a jejunum segment distended with saline solution. The intraluminal pressure was maintained in 25cm of water for 2h. The mucosal samples collected (0h, 2h of distension, 2h and 12h of decompression) were analyzed with scan electronic microscopy (SEM). The area and the perimeter of the villi, as well as their density, were analyzed using a specific software for image analysis (Image J). The luminal distention and decompression induced an increase on villi dimensions (area and perimeter). This ultrastructural alteration occurred just 12h after decompression, possibily due to edema caused by the increase of vascular permeability resulting from ischemia and reperfusion of the intestine mucosa. The intraluminal distension of the equine jejune caused a delayed increase of the intestine villi dimensions.
