Metastatic clear-cell renal carcinoma: an exceptional cause of ileocolonic intussusception in adults

Introduction: Intussusceptions in adults are rare, representing 1% to 5% of intestinal obstructions in this age group. This condition can be caused by benign and malignant lesions acting as lead points, the latter being the most frequent. Furthermore, the diagnosis is challenging due to the non-specific symptoms with variable duration. Case Presentation: A 43-year-old man, with a history of localized clear-cell renal carcinoma (ccRCC) treated 9 years earlier with a right radical nephrectomy, presented with bowel obstruction symptoms. An abdominal computed tomography scan showed an ileocolonic intussusception. Hence, the patient required a right hemicolectomy with ileotransverse anastomosis. The histopathological analysis showed a metastatic ccRC to the terminal ileum causing the intussusception. Discussion: Adult intussusceptions are rare. However, they should be considered in the differential diagnosis of patients with abdominal pain and symptoms of bowel obstruction. Metastases of renal cancer to the small bowel are uncommon and even more so in the form of intussusception. Definitive treatment must be tailored to the patient's condition and underlying cause.

Intususcepción apendicular por foco endometriósico: un caso clínico / Appendiceal intussusception caused by endometriosis: a clinical case

Resumen Objetivo: Reportar el caso de una paciente con intususcepción apendicular (IA), condición infrecuente, secundario a foco de endometriosis, patología que en los últimos años ha presentado un aumento en su incidencia. Material y Método: Historia clínica, imágenes preoperatorias e intraoperatorias obtenidas de la ficha clínica. Resultados: Mujer de 35 años con dolor abdominal crónico de 4 meses de evolución. Se realiza estudio colonoscópico evidenciando lesión de 15 x 8 mm en ostium apendicular intususceptada al lumen cecal, y enteroclisis por tomografía axial computarizada (TC) que confirma IA. Se realiza una resección ileocecal laparoscópica demostrando la invaginación del apéndice con biopsia que muestra un foco de endometrioma. Discusión: La IA es una condición infrecuente con una incidencia cercana al 0,01% en la población general. Las patologías benignas son la principal causa (77%), siendo la endometriosis la causa más frecuente. Conclusión: La IA por endometriosis es anecdótica, con sintomatología poco específica. Los estudios disponibles pueden orientar adecuadamente la presencia de IA, sin embargo, en algunas ocasiones puede confundirse con patologías neoplásicas, donde cobra importancia la cirugía para dilucidar la etiología.

Objective: To report the case of a patient with appendicular intussusception (AI), an infrequent condition secondary to a focus of endometriosis, a pathology that has increased incidence in recent years. Material and Method: Clinical case, history and images obtained from the clinical file and intraoperative records with the consent of the patient. Results: A 35-year-old woman with abdominal pain. Colonoscopy study showing a 15 × 8 mm lesion in the appendicular ostium intussuscepted to the cecal lumen, and a computerized tomography (CT) enteroclysis confirming AI. A laparoscopic ileocecal resection is performed, demonstrating invagination of the appendix secondary to an endometrioma focus. Discussion: AI is a rare condition, with an incidence close to 0.01% in the general population. Benign pathologies are the main cause (77%), endometriosis being the most frequent cause. Conclusion: AI due to endometriosis is anecdotal, with unspecific symptoms. The available studies can adequately guide the presence of AI, however, on some occasions it can be confused with neoplastic pathologies, where surgery is important to elucidate the etiology.

Asociación de invaginación y malrotación intestinal con el Síndrome de Waugh / Association of invagination and intestinal malrotation with Waugh's síndrome

RESUMEN El síndrome de Waugh es una patología del neonato caracterizado por la asociación de una malrotación intestinal a una intususcepción. Existen pocos casos documentados en la literatura, lo que conlleva una baja incidencia. Presentamos el caso de un neonato femenino de 4 meses de edad quien fue llevada a tratamiento quirúrgico con oclusión intestinal y evolución posoperatoria favorable. El objetivo del trabajo es presentar el caso de un síndrome de Waugh en un lactante en cuyo cuadro se debe mantener una alta sospecha diagnostica, apoyándose con la toma de estudios de imagen complementarios ante un cuadro de dolor abdominal en pacientes lactantes cuya resolución diagnostica siempre resulta un reto para el médico. Si bien estas acciones podrán en un futuro reflejar un aumento en la incidencia de este síndrome, también es posible que el manejo de dicho síndrome se optimice. Paciente femenina de 4 meses de edad la cual fue sometida a tres intentos de desinvaginación hidrostática antes de pasar a laparotomía exploradora para corrección definitiva de su patología. La asociación de invaginación con mal rotación intestinal actualmente es subdiagnósticada, debido a la tendencia conservadora actual. Es importante realizar más estudios de imagen antes de iniciar con cualquier estrategia terapéutica, para no retrasar el manejo quirúrgico definitivo que este requiere. De esta manera se podrá ganar en la calidad de los pronósticos de los pacientes(AU)

ABSTRACT Waugh's syndrome is a neonatal pathology characterized by the association of intestinal malrotation and intussusception. There is a low number of cases documented in literature, which implies low incidence. Here is a 4 months-old female neonate who was surgically treated because of intestinal occlusion, and her postoperative recovery was favorable. The objective was to present a Waugh's syndrome case in a newborn in which high diagnostic suspicion is important, supported by complementary imaging studies when we face abdominal pain in neonates whose diagnostic resolution is always a challenge to the physician. These actions may show an increase in the incidence of this syndrome in the future; it is also possible that the management of this disease be optimized. Hydrostatic disinvagination was performed three times in this patient before undergoing exploratory laparotomy for final correction of her pathology. The association of invagination and intestinal malrotation is poorly diagnosed at present, due to current conservative tendencies. However, it is important to perform more imaging studies before adopting any therapeutic strategy to avoid delays in the definitive surgical management of this disease(AU)

Coloanal intussusception in adults due to lipoma / Intussuscepção colo-anal decorrente de lipoma em adulto

ABSTRACT Adult intussusception is a rare condition. But coloanal intussusception is an exception. Malignant lesions are the most common cause of colonic intussusception, and in this aspect, differ from childhood intussusception. We present a case wherein the patient had a lipoma of the sigmoid colon that caused an immense prolapse through the anus. Very few cases of coloanal intussusception are reported in adults, and we discuss the diagnostic tools and the management of this rare surgical entity.

RESUMO A intussuscepção no adulto é uma entidade rara. Mas a intussuscepção colo-anal é uma exceção. Lesões malignas são a causa mais comum de intussuscepção colônica e, neste aspecto, difere da intussuscepção infantil. Apresentamos um caso de lipoma do cólon sigmoide que causou um prolapso imenso através do ânus. Muito poucos casos de intussuscepção colo-anal foram relatados em adultos e discutimos as ferramentas diagnósticas e o tratamento dessa entidade cirúrgica rara.

Intususcepción intestinal debido a un pólipo fibroide inflamatorio (tumor de vanek) / Intestinal intussusception due to an inflammatory fibroid polyp (vanek tumor)

La intususcepción en un adulto debe hacer sospechar un tumor (benigno o potencialmente riesgoso); el diagnóstico certero es crucial para el tratamiento adecuado del paciente1. Alrededor del 90% de estos casos se dan en el intestino delgado y colon, el 10% restante se originan en el estómago y en estomas creados quirúrgicamente2. En los adultos, aproximadamente 90% de los casos de intususcepción son secundarios a una lesión definible3. El tumor de Vanek o pólipo fibroide inflamatorio, se conoce como una lesión benigna, rara, de localización submucosa, no encapsulada, cuya ubicación puede darse a lo largo del tracto digestivo, siendo más común en el antro gástrico (80 %), aunque también se ha descrito en la unión gastroesofágica, duodeno, yeyuno, íleon y colon4.

Intussusception in an adult must make us suspect the presence of a tumor (benign or potentially dangerous) as the most frequent cause. Accurate diagnosis is of great importance in order to provide appropriate treatment and improve patient prognosis1. About 90% of these cases occur in the small intestine and colon, and the remaining 10% originate in the stomach and surgically created ostomas2. In adults, approximately 90% of cases of intussusception are secondary to a definable lesión3. The Vanek's tumor or inflammatory fibroid polyp (IFP) is a rare benign lesion of submucosal location, not encapsulated, that may be located throughout the digestive tract, being more common in the gastric antrum (80%), although it has also been described in the gastroesophageal junction, duodenum, jejunum, ileum and colon4.

Etiologies tumorales des invaginations intestinales aiguës secondaires chez l'enfant. Cas de deux observations

Introduction : L'invagination intestinale aiguë est connue comme pouvant survenir sur une tumeur chez le grand enfant. Dans ce travail, nous rapportons le cas de deux patientes tout en précisant la nature histologique, le traitement effectué et le pronostic de ces tumeurs.Observations : Les deux patientes respectivement âgées de 3 ans et demi et 11 ans ont été admises en urgence pour douleur abdominale aiguë paroxystique. Le diagnostic de l'invagination intestinale évoqué à l'examen clinique a été confirmé par l'échographie abdominale : iléo-cæco-colique dans le premier cas et iléo-iléale dans le second. La cause tumorale de l'invagination été faite en per opératoire lors de la laparotomie. Nous avons pratiqué une désinvagination, résection tumorale et anastomose intestinale. L'examen histologique des pièces tumorales a mis en évidence un lymphome malin diffus centrocytique, centroblastique du cæcum dans le premier cas (patiente de 3 ans) et un polype adénomateux festonné en dysplasie de bas grade de l'iléon dans le second (patiente de 11 ans). L'évolution après cure de chimiothérapie chez la patiente de 3 ans a été satisfaisante et le recul à deux ans ne montre pas de récidive. Les suites sont aussi simples à 1 mois post-opératoire chez la patiente de 11 ans.Conclusion : Les invaginations intestinales peuvent être un mode de révélation de tumeurs lorsqu'elles surviennent au-delà de la petite enfance. La précision de la nature bénigne ou maligne de ces tumeurs par l'examen immuno-histochimique est capitale et déterminante pour le traitement et le pronostic

Intususcepción ileosigmoidea en adulto: Reporte de caso y revisión de la literatura / Ileosigmoideal intussusception in an adult: Case report and review of the literature

La intususcepción en el adulto presenta una baja incidencia. Se puede observar en diferentes localizaciones y dentro de las menos frecuentes se encuentra la íleo-sigmoidea. Su etiología es diversa, siendo más frecuentes las causas malignas cuando se presenta a nivel del colon en edad adulta. La sospecha diagnóstica apoyada de la tomografía computada de abdomen, puede, además de corroborar el diagnóstico, esclarecer la etiología de la misma y orientar sobre la opción terapéutica más adecuada para el paciente

Intussusception in adults has low incidence. It can be seen at different locations and within less frequent ileosigmoid is. The etiology is diverse, being more frequent causes malignant when it occurs in the colon into adulthood. The suspected diagnosis supported by computed tomography of the abdomen, may also corroborate the diagnosis, clarify the etiology of it and guidance on the most appropriate treatment option for the patient

El primer síntoma presentado fueron 40% vómitos, 25% diarrea, 15% heces con sangre y 5% distensión abdominal; la sintomatología previa a la cirugía fue: distensión abdominal (30%) dolor o llanto inconsolable (25%), paro de evacuaciones (15%), fiebre y diarrea (10%), vómitos y heces con sangre (5%). Al 70% se realizó tacto rectal, de estos 5% se palpo masa en recto y 25% presentó salida de heces con sangre. Al 100% se realizó laparotomía, la localización principal fue ileo-colica en el 50% de los casos. Conclusión: La presentación clínica de II en lactantes es atípica, lo que hace necesario realizar un examen físico exhaustivo para detectar signos clínicos característicos de la enfermedad...(AU)

Chronic Intussusception Caused by Diffuse Large B-Cell Lymphoma in a 6-Year-Old Girl Presenting with Abdominal Pain and Constipation for 2 Months

The classical triad of abdominal pain, vomiting, and bloody stool is absent in chronic intussusception for more than 2 weeks. Here, we report a 6-year-old female with recurrent abdominal pain for 2 months. Ultrasonography of the abdomen revealed an ileocolic-type intussusception. The lesion accompanying the tight fibrous adhesion was treated by resection and ileocolic anastomosis. It was diagnosed as intussusception with diffuse large B-cell lymphoma. A high index of suspicion for abdominal pain in children should result in the correct diagnosis and appropriate management.

Echocardiographic detection of intimo‑intimal intussusception in a patient with acute Stanford type A aortic dissection.

Intimo‑intimal intussusception is a very rare and unusual complication of type A dissections, typically noted on TEE exam. It has been reported in a few cases in the cardiothoracic surgical and radiology literature, and even more rarely in the cardiac anesthesia/TEE literature. This uncommon variation occurs in severe, acute, type A dissections when the ascending aortic intima circumferentially strips and detaches from the media and forms a tube‑like structure which may either prolapse antegrade into the ascending aortic lumen or retrograde into the left ventricular (LV) outflow tract and LV cavity. Antegrade intussusceptions may be severe enough to partially or completely occlude the ostia of the innominate, left common carotid, and left subclavian arteries producing acute neurologic symptoms. Retrograde intussusceptions may severely impair LV filling in diastole, can worsen aortic insufficiency, mitral regurgitation, as well as produce occlusion of the coronary ostia and acute coronary ischemia. Here, we describe the incidental finding of a retrograde intussusception that was not visualized on computed tomography scan but by intraoperative TEE examination, in a patient with a severe, extensive type A dissection.

Intussuscepção uterina em uma cadela Yorkshire Terrier / Uterine intussusception in a Yorkshire terrier bitch

A intussuscepção uterina é condição rara em pequenos animais. No presente relato descreve-se um caso de intussuscepção uterina em um canino, fêmea Yorkshire Terrier no pós-parto imediato, diagnosticada por meio de laparotomia exploratória e pela avaliação anatomopatológica. Realizou-se a ovariossalpingo-histerectomia (OSH) como tratamento definitivo para a alteração. Conclui-se, portanto, que a intussuscepção uterina pode ocorrer em cadelas, de forma espontânea no pós-parto imediato.

Uterine intussusception has rarely been described in small animals. In this report we describe a case of uterine intussusception in a female Yorkshire terrier immediately postpartum, diagnosed by exploratory laparotomy and anatomopathologic evaluation. Ovariosalpingohisterectomy (OSH) was performed as definitive treatment. It is concluded that the intussusception of the uterus may occur spontaneously in dogs immediately postpartum.

Intussuscepção colônica em adulto: relato de caso / Adult colonic intussusception: a case report

Intussuscepção é a penetração de um segmento do tubo gastrintestinal (TGI) em direção ao segmento adjacente. É rara em adultos e de diagnóstico difícil. Possui na faixa etária adulta, em geral, um fator precipitante. Este trabalho relata paciente adulta que se apresentou à emergência cirúrgica com abdome agudo. Realizada laparotomia de emergência que evidenciou invaginação colônica. A patologia confirmou tratar-se de lipoma como cabeça do intussuscepto.

Intussusception is the penetration of a digestive tract segment into an adjacent segment. It is rare in adults and difficult to diagnose. For adults it generally involves a precipitating factor. This paper describes an adult patient who entered the emergency department with acute surgical abdomen. Emergency laparotomy revealed colonic intussusception. The pathology confirmed a lipoma as the head of this intussusceptum.

Rectal hyposensitivity and functional anorectal outlet obstruction are common entities in patients with functional constipation but are not significantly associated

BACKGROUND/AIMS: The causes of functional anorectal outlet obstruction (outlet obstruction) include functional defecation disorder (FDD), rectocele, and rectal intussusception (RI). It is unclear whether outlet obstruction is associated with rectal hyposensitivity (RH) in patients with functional constipation (FC). The aim of this study was to determine the association between RH and outlet obstruction in patients with FC. METHODS: This was a retrospective study using a prospectively collected constipation database, and the population comprised 107 patients with FC (100 females; median age, 49 years). We performed anorectal manometry, defecography, rectal barostat, and at least two tests (balloon expulsion test, electromyography, or colon transit time study). RH was defined as one or more sensory threshold pressures raised beyond the normal range on rectal barostat. We investigated the association between the presence of RH and an outlet obstruction such as large rectocele (> 2 cm in size), RI, or FDD. RESULTS: Forty patients (37.4%) had RH. No significant difference was observed in RH between patients with small and large rectoceles (22 [44.9%] vs. 18 [31%], respectively; p = 0.140). No significant difference was observed in RH between the non-RI and RI groups (36 [36.7%] vs. 4 [30.8%], respectively; p = 0.599). Furthermore, no significant difference in RH was observed between the non-FDD and FDD groups (19 [35.8%] vs. 21 [38.9%], respectively; p = 0.745). CONCLUSIONS: RH and outlet obstruction are common entities but appear not to be significantly associated.

Intussusception: As the Cause of Mechanical Bowel Obstruction in Adults / 대한소화기학회지

BACKGROUND/AIMS: Intussusception in adults is rarely seen and causes misdiagnosis due to its appearance with various clinical findings. The cause of intussusception in adults is frequently organic lesions. In this study, the underlying etiologic factors, diagnostic methods and alternative methods of treatment are discussed in the light of the literature. METHODS: In this study, a retrospective evaluation was performed on 47 cases with the diagnoses of intussusception, who were operated on for bowel obstruction between 1990-2011 in Department of Surgery of Necmettin Erbakan University Meram Medical Faculty. Data related to presentation, diagnosis, treatment and pathology were analyzed. RESULTS: Twenty-four of the patients (51%) were female, and 23 were male (49%). Mean age (year) was 49 (range: 23-78) in female group, and 50 (range: 17-72) in male group. All patients presented mechanical bowel obstruction findings and underwent operation. Intussusception was caused by benign and malignant tumors in 38 patients, and other reasons in 3 cases. No reason could be determined in the other 6 cases. Only small intestine resection was applied in 29 cases, and large intestine resection was also applied in 17 cases. Reduction and fixation surgery was performed in one patient. No postoperative mortality was observed. CONCLUSIONS: Adult intussusception remains a rare cause of abdominal pain. Diagnosis of intussusception in adults is still difficult. Main treatment was surgical in most cases.

Giant ileal inflammatory fibroid polyp: a rare cause of intestinal intussusception

Ileal inflammatory fibroid polyp is a rare non-neoplastic lesion of the gastrointestinal tract. Intussusception caused by an inflammatory fibroid polyps is uncommon. The authors report a case of a 75 year-old female patient presenting with ileal obstruction due to intussusception of a polypoid lesion. The patient underwent surgical treatment and histopathology confirmed the diagnosis. (AU)

Os pólipos fibroides inflamatórios são raras lesões não neoplásicas do trato gastrointestinal e a intussuscepção devido a essa entidade é incomum. Os autores relatam um caso de paciente do sexo feminino, 75 anos, que apresentou obstrução ileal devido a uma intussuscepção por lesão polipoide. A paciente foi submetida a tratamento cirúrgico, sendo diagnosticado pólipo fibroide inflamatório do íleo. (AU)

Invaginación intestinal / Intussusception

La invaginación intestinal o intususcepción es causa frecuente de dolor abdominal agudo y de obstrucción intestinal en la infancia. Clínicamente se caracteriza por dolor abdominal intermitente, masa abdominal, y evacuaciones con sangre. Actualmente la ecografía abdominal ha desarrollado un papel importante en el diagnóstico temprano de esta patología, con alto porcentaje de certeza diagnóstica.

Invaginación apendicular / Cecal appendix invagination

Cecal appendix invagination was first described by Mc Kidd in 1858, however, due to its low frequency and nonspecific presentation, it is usually a radiological or intraoperative finding. During surgery, the therapeutic approach may vary from an appendectomy to a right hemicolectomy. The selected technique will depend of the suspected diagnosis, which will undoubtedly also influenced by surgeon experience. We present a case of a male patient aged 57 years old, with the intraoperative finding of appendiceal intussusception. The laparoscopic dissection of the cecum revealed an inflammatory appendix, soft to palpation with graspers. A large section of the appendix base with linear stapler was made. The final biopsy and surgical specimen showed an appendiceal inflammation without atypia.

La invaginación del apéndice cecal fue descrita por primera vez en 1858, sin embargo, debido a su baja frecuencia y presentación inespecífica suele constituir un hallazgo radiológico o intraoperatorio. En este último caso la conducta terapéutica puede variar desde la apendicectomía hasta la hemicolectomía, ya que se debe plantear a la neoplasia cecal dentro de los diagnósticos diferenciales y, en virtud de ello, la decisión operatoria puede obligar a la hemicolectomía derecha. Esta decisión se verá influida también por la experiencia del cirujano. Se presenta el caso de un paciente de sexo masculino de 57 años de edad con el hallazgo intraoperatorio de invaginación apendicular. Se realizó una disección amplia del ciego por vía laparoscópica y a la palpación con las pinzas el apéndice y el ciego impresionaban de consistencia blanda, no tumoral. Debido a estos hallazgos se decidió realizar la apendicectomía realizando una sección amplia de la base apendicular con stapler lineal cortante. La biopsia definitiva de la pieza operatoria informó un proceso inflamatorio apendicular sin hallazgos sugerentes de atipías.
