Roux-en-Y partial volvulus in biliary-digestive reconstruction in children.

Various complications occur after a biliary-digestive reconstruction. Volvulus of a segment of the biliodigestive loop has not been described. Two patients who underwent biliodigestive bypass, years later, began with sudden and intense abdominal pain, associated with a volvulus with necrosis of a segment of this biliodigestive loop. This complication occurred many years after the initial correction, and manifested with sudden abdominal pain without impaired liver function, as occurred in these patients.

Diversas complicaciones pueden ocurrir después de una reconstrucción biliodigestiva. El vólvulo de un segmento del asa biliodigestiva no ha sido descrito. Dos pacientes operados de derivación biliodigestiva, años después iniciaron con dolor abdominal súbito e intenso, asociado a un vólvulo con necrosis de un segmento de la asa interpuesta. Se ha descrito el vólvulo de toda el asa interpuesta, pero no el de solo una pequeña porción de esta. La complicación ocurrió muchos años después de la corrección inicial y se manifiesto con dolor abdominal súbito sin deterioro de la función hepática, como sucedió en estos pacientes.

Embarazo con miomatosis uterina complicado con isquemia intestinal: reporte de un caso / Pregnancy with uterine myomatosis complicated by intestinal ischemia: case report

Resumen Los miomas uterinos, también conocidos como fibromas o leiomiomas, son los tumores uterinos benignos más prevalentes. Afectan a las mujeres principalmente durante sus años reproductivos y se diagnostican hasta en un 70% de las mujeres blancas y en más del 80% de las mujeres de ascendencia africana durante su vida, con una prevalencia durante el embarazo del 2% al 10%. Pueden ser asintomáticos hasta en un 70% de las pacientes, y se estima que pueden ocurrir complicaciones en aproximadamente una de cada 10 mujeres embarazadas. Se han asociado a complicaciones y resultados adversos del embarazo, según su tamaño y ubicación en el útero, y pueden manifestarse de diferentes formas. Presentamos el caso de una mujer de 30 años, con embarazo en el tercer trimestre, quien consultó por dolor abdominal, con ecografías obstétricas durante su control prenatal que reportaban miomatosis uterina, quien presentó isquemia intestinal por un vólvulo de intestino delgado versus compresión extrínseca.

Abstract Uterine fibroids, also known as fibroids or leiomyomas, are the most prevalent benign uterine tumors, affecting women mainly during their reproductive years and are diagnosed in up to 70% of white women and more than 80% of women of African descent during their lifetime, with a prevalence during pregnancy of 2% to 10%; they may be asymptomatic in up to 70% of patients, and it is estimated that complications may occur in approximately one in 10 pregnant women. They have been associated with complications and adverse pregnancy outcomes, depending on their size and location in the uterus, they can manifest in different ways. We present the case of a 30-year-old woman, pregnant in the third trimester, who consulted for abdominal pain, with obstetric ultrasound scans during her prenatal check-up reporting uterine myomatosis, who presented intestinal ischemia due to small bowel volvulus versus extrinsic compression.

Pediatric sigmoid volvulus due to Chagas disease.

Exposure and infections by Trypanosoma cruzi are the fourth cause of loss of potential life years between parasitic and infectious diseases. We describe the case of a 11-year-old patient with intestinal occlusion, surgically treated with intestinal volvulus, the surgical specimen is sent to histopathology reporting Chagasic megacolon. The age range of presentation is a challenge in the absence of nonspecific symptoms. There is no pediatric statistical data that define trypanosomiasis in a latent or chronic state and will be diagnosed in adult stages due to the physiopathological alterations that they will present.

La exposición y las infecciones por Trypanosoma cruzi ocupan el cuarto lugar entre las causas de pérdida de años de vida potenciales por enfermedades parasitarias e infecciosas. Se describe el caso de un niño de 11 años, con cuadro de oclusión intestinal, intervenido quirúrgicamente con datos de vólvulo intestinal. La pieza quirúrgica se envió a histopatología, que reportó megacolon chagásico. El rango de edad de presentación es un reto ante la falta de síntomas inespecíficos. No se cuenta con datos estadísticos pediátricos que definan la tripanosomiasis en estado latente o crónico, y estos niños serán diagnosticados en la etapa adulta por las alteraciones fisiopatológicas que presentarán.

Death caused by appendicular knotting and small-bowel strangulation in a child: A case report and review.

Acute appendicitis is one of the most common surgical emergencies in paediatrics. However, acute appendicitis in early infancy is an uncommon condition. Furthermore, strangulation of the small intestine through appendicular knotting is described as very unusual in the literature and is generally not well-diagnosed in the clinical context. This article reports the case of a 23-month-old girl who entered the emergency department with a three-day history of abdominal symptoms and who died in less than 24 hours without receiving surgical intervention. The case turned judicial at the request of the parents who claimed lack of clarity in the diagnosis. A medico-legal autopsy was ordered to clarify the cause and manner of death. The autopsy documented herniation, strangulation and torsion of a 70 cm segment of the jejunum/ileum through an appendicular knot caused by the attachment of the distal end of the inflamed appendage to the ileum. The case is relevant because it is the first case of death by appendicular knot and strangulation of small bowel in an infant reported in the literature. The importance of autopsy to clarify the clinical diagnosis is noted.

[Megacolon and sigmoid volvulus: incidence and physiopathology]. / Megacolon y vólvulo de sigmoides: incidencia y fisiopatología.

The etiology of Megacolon is multiple. One of these causes and the most frequent is Chagas disease. Its complication: sigmoid volvulus was de main diagnosis in the admitted patients at the Bolivian and Japanese Gastroenterological Institute of Cochabamba Bolivia. It usually affects people of a low economic income. In this Gastroenterological Hospital a transversal and prospective study has been done, in order to know the real incidence and the physiopathology of this disease. In a six year period, from 2000 to 2006, 8.954 patients were admitted to the Hospital: of these, 814 (9.09%), where diagnosticated as lower intestinal obstruction. In 608 (74.7%) the final diagnosis was sigmoid torsion. Radiological diagnosis was made in 84% of the patients and endoscopic decompression was successful in 88.7%. As reported in the medical literature, the main cause of megacolon in this part of the world is Chagas disease. In our investigation 22% (98 patients), were serology positive to Chagas disease, and another 21.44% (95 patients) were serology negative. They were coca leaf chewers. One of coca leaf compounds is cocaine which blocks the adrenaline and noradrenaline degradation by mean of monoamine oxidase inactivation. These two hormones stay a long term of time in the target organ: the large bowel. By this mean chronic and persistent vessel constriction develops intestinal wall atrophy and lower resistance to the intraintestinal pressure.

Chylous jejunal cyst causing volvulus in a child: case report and literature review.

Chylous jejunal cysts are extremely rare entities and if not diagnosed promptly may lead to severe complications like bowel obstruction, loss of small bowel and even death. We present the case of a 4 year-old-male referred to our institution with severe abdominal pain, constipation, abdominal distention and radiological findings of large amount of fluid in the lower abdomen with associated bowel obstruction. Operative findings were that of large chylous jejunal cyst causing segmental volvulus. Resection of the involved jejunal segment and cyst along with bowel detorsion was undertaken. Literature review on the subject follows.

Linfangioma mesentérico multiquístico como causa de vólvulo intestinal / Mesenteric lymphangioma causing volvulus: report of one case

Lymphangiomas are rare benign lesions, most commonly seen in children and adolescents. Their intra-abdominal presentation is uncommon. We report a 19 years old male, presenting to the emergency room with abdominal pain associated with fever, vomiting and abdominal distension. There was a history of multiple previous consultations for abdominal pain. A plain abdominal X-ray examination suggested a bowel obstruction. At surgery a volvulus and dilation of the small bowel in relation to a vascular malformation was found, excising 40 cm of jejunum with an end-to-end intestinal anastomosis. The pathology report showed a Mesenteric Multicystic Lymphangioma. Presently, the patient is in good conditions.

Los linfangiomas son lesiones benignas, de baja incidencia, más comunes en niños y adolescentes. Con muy baja frecuencia son intraabdominales y poseen presentación clínica variable, yendo desde el hallazgo clínico hasta pacientes con riesgo vital por abdomen agudo. Presentamos el caso de un paciente de 19 años, sin antecedentes mórbidos que acude a urgencias por dolor abdominal asociado a fiebre, vómitos y distensión abdominal; la radiografía simple es sugerente de obstrucción intestinal. En laparotomía exploradora se encuentra un vólvulo y dilatación del intestino delgado en relación a una malformación vascular y lesiones multilobuladas en mesenterio. Se resecan 40 cm de yeyuno y realiza anastomosis término-terminal. La histología reveló un Linfangioma Multiquístico Mesentérico. El paciente evoluciona en buenas condiciones generales y se mantiene control clínico e imagenológico seriado. Aunque infrecuente, es uno de los diagnósticos diferenciales de abdomen agudo. A pesar de su naturaleza benigna puede llegar a comprometer el pronóstico vital del paciente.

[Dolichomegacolon of the Andes and intestinal volvulus due to altitude]. / Dolicomegacolon Andino y vólvulos intestinales de altura.

Sigmoid volvulus is a frequent cause of emergencies in hospitals in the Andean area, representing more than 50% of all intestinal obstructions. Andean dolichomegacolon (DCMA) and retractile mesocolonitis are the main contributing factors for volvulus. The mesocolonitis nears the proximal and distal segment of the sigmoid handle, favoring its torsion. Copious intake of fermentable food is the precipitating factor for volvulus. The majority of patients are seen during sowing and harvest periods, in which the consumption of this type of food increases. Andean people who live at an altitude of 3,000 m have a larger and thicker colon than coastal residents. We call this acquired characteristic the Andean dolichomegacolon (DCMA). A fiber-rich diet may inhibit the histological phenomenon known as elastogenesis, developing--over the years--the megacolon. Another important factor may be the lower atmospheric pressure in the altitude, and according to Boyle and Mariotte's physical law, the expansion of intraluminal gas may have an influence on intestinal enlargement. DCMA has many special anatomic, clinical, radiological, histological and serological features which make it different from the . chagasic megacolon. Mild emergency procedures may be performed to treat the sigmoid volvulus, such as endoscopic disvolvulation. Changing the colon rotation is helpful in diminishing abdominal pressure and restore complete blood circulation. An emergency surgery treatment must take the patient's general condition and the colon handle condition during surgery as a guiding point. High rates of mortality are found in relation to elderly patients, disease evolution time and stage of intestinal ischemia. Other new therapeutic procedures such as percutaneous sigmoidpexy, laparoscopic sigmoidectomy and mesosigmoplasty are under review, and have precise indications. Wider series are needed to evaluate them better.

Manejo quirúrgico del vólvulo de sigmoides en el Hospital Departamental de Huancavelica durante el periodo 2004-2007 / Surgical management of sigmoid volvulus at the Departmental Hospital of Huancavelica during the period 2004-2007

El vólvulo de sigmoides es una emergencia frecuente en los hospitales del área andina, donde representa más del 50 por ciento de todas las obstrucciones intestinales. El Dolicomegacolon Andino (DCMA) y la mesocolonitis retráctil son los principales factores predisponentes del vólvulo; la mesocolonitis aproxima el segmento proximal y distal del asa sigmoidea, favoreciendo su torsión. La ingesta copiosa de alimentos fermentables constituye el factor precipitante del vólvulo; la mayoría de los pacientes son atendidos durante las épocas de cosecha y siembra, períodos en los que aumenta su consumo. Los andinos que viven sobre los 3,000 metros de altura tienen el colon de mayor longitud y diámetro que los habitantes del llano, ésta característica adquirida la llamamos el Dolicomegacolon Andino (DCMA). El alto contenido de fibra dietaria inhibiría el fenómeno histológico denominado elastogénesis, induciendo a los largo de los años el megacolon. El objetivo principal del presente trabajo es evaluar los resultados de las técnicas quirúrgicas empleadas en pacientes con diagnóstico de vólvulo de sigmoides en el Hospital Departamental de Huancavelica-MINSA, durante el periodo 2004-2007. La edad de los pacientes fluctúa entre los 19 y los 76 años de edad, siendo más frecuente en el grupo etario de 40 a los 60 años, asimismo se ve que el cuadro se presenta con mayor frecuencia en el sexo masculino siendo la proporción de 4 a 1 en relación a los pacientes de sexo femenino. El número de pacientes con diagnóstico de vólvulo de colon fueron en total 161 de los cuales se realizaron resección y anastomosis primaria en 134 casos y procedimiento de Hartmann en 27 casos. La complicación más frecuente fue la infección de herida operatoria en 5 casos en pacientes sometidos a resección y anastomosis primaria y 2 casos en pacientes que fueron sometidos a procedimiento de Hartmann. Seguida de infección respiratoria y dehiscencia de anastomosis en 2 casos en pacientes sometidos a...

Sigmoid volvulus is a common emergency in hospitals in the Andean region, accounting for over 50 per cent of all intestinal obstructions. The Andean dolichomegacolon (DCMA) and retractile mesocolonitis are the main predisposing factors for volvulus; mesocolonitis brings the proximal and distal segment closer to the sigmoid loop, favoring a twist. Massive intake of fermentable food is the precipitating factor for volvulus. Most patients are seen during harvest and sowing seasons which are the periods when intake increases. Andean people who live above 3.000 meters have a longer and wider colon than inhabitants of the plain. This characteristic is called Andean dolichomegacolon (DCMA). The high content of dietary fiber inhibiting the histological phenomenon is known as elastogenesis, and over the years leads to megacolon. The main objective of this work is to evaluate the results of the surgical techniques used in patients with a sigmoid volvulus diagnosis in the Department Hospital of Huancavelica, Ministry of Health, during the period of 2004 - 2007. Patients' age range from 19 to 76 years old and it is more common to find in the 40 to 60 age group. Also, it is more frequently seen in male than female patients, on a 4 to 1 ratio. The number of patients diagnosed with colon volvulus were 161 in total, of which 134 cases underwent primary resection and anastomosis, and Hartmann's procedure was performed on 27 cases. The most common complication was operation wound infection in 5 cases in patients undergoing primary resection and anastomosis and in 2 cases on patients who underwent Hartmann's procedure. The next most frequent complication was respiratory infection and dehiscence of anastomosis in 2 cases on patients undergoing primary resection and anastomosis, and 2 cases in patients who underwent Hartmanns procedure. As to mortality of this condition, according to the results obtained in the present study, 2 patients who underwent primary resection and...

Úlceras em megacólons chagásicos operados na urgência e eletivamente / Ulcerations in Chagas' megacolon operated at urgency and electively

RACIONAL: O megacólon é uma doença freqüente no nosso meio e abordado na urgência pelas suas complicações como fecalomas, volvos e perfurações. As úlceras de estases nos megacólons contribuem como prováveis sítios de perfurações OBJETIVO: Comparar as freqüências de úlceras de decúbito em megacólons chagásicos operados na urgência, por volvo e fecaloma, e eletivamente, objetivando melhor conduta cirúrgica na urgência MATERIAL E MÉTODOS: Analisaram-se os laudos de 356 exames anatomopatológicos de ressecções colônicas de pacientes operados por megacólon chagásico na urgência (102 casos; 29 por cento) e eletivamente (254 casos; 71 por cento), no período de 1980 a 2000. As indicações cirúrgicas de urgência foram atribuídas a volvo (71 casos; 69,6 por cento), fecaloma (25 casos; 24,5 por cento), abdome agudo perfurativo após sondagem retal ou sigmoidoscopia (6 casos; 5,9 por cento). Compararam-se as freqüências de úlceras nos dois grupos de peças cirúrgicas, com a utilização do teste do qui-quadrado RESULTADOS: Nos laudos das peças cirúrgicas obtidas nas cirurgias de urgência, constatou-se o registro de úlceras em 26 casos (25,5 por cento); nas peças de ressecções eletivas verificaram-se úlceras em 21 casos (8,25 por cento). A diferença observada foi estatisticamente significante. A comparação dos grupos de volvo, fecaloma e volvo com fecaloma, em separado com o grupo das cirurgias eletivas, evidenciou diferenças significantes em relação ao volvo e ao fecaloma CONCLUSÃO: A freqüência muito maior de úlceras nos megas operados em caráter de urgência enfatiza a necessidade da ressecção imediata do cólon sigmóide, ao invés da conduta conservadora de simples colostomia descompressiva, mesmo naquelas laparotomias exploradoras em que o exame macroscópico do sigmóide não mostre sinais de necrose. Desta forma, deve-se prevenir a ocorrência de perfuração do megacólon no pós-operatório mediato, com conseqüências usualmente graves.

BACKGROUD: The megacolon is a frequent disease in our emergencie hospital, and approached in the urgency by your complications as fecal impaction, volvulus and perforations. The ulcerations in the megacolons contribute as probable sites of perforations AIM: To compare the frequencies of stercoral ulceration in Chagas' megacolon operated at urgency, by volvulus or fecal impaction, and electively, aiming at a better surgical conduct in the urgency surgery METHODS: It was analyzed 356 anatomy-pathological exams from colon resection of operated patients due to Chagas' megacolon at urgency (102 cases; 29 percent) and electively (254 cases; 71 percent), from 1980 to 2000. The surgical urgency indications were attributed to volvulus (71 cases; 69,6 percent), fecal impaction (25 cases; 24,5 percent), perforated acute abdomen after rectal catheter or sigmoidoscopy (6 cases; 5,9 percent). The ulceration frequency was compared in both groups of resections, using chi-square RESULTS: The pathological anatomy - of surgery resection obtained at urgency surgeries, showed 26 cases of ulceration (25,5 percent) and in electively resections were verified 21 cases of ulceration (8,25 percent). The difference observed was statistically significant. The comparison among the groups of volvulus; fecal impaction and volvulus with fecal impaction, separately with electively surgery group evidenced significant differences in relation to volvulus and fecal impaction CONCLUSIONS: The higher frequency of ulcerations in the megacolon operated at urgency character emphasizes the needs of immediate resection of sigmoid colon, instead of conservative conduct of simple decompression colostomy, even in exploration laparotomy which the macroscopic examination of sigmoid does not show necrotic signs. This way, should prevent the occurrence of perforation in megacolon at mediate postoperative, with serious results.

Small bowel volvulus secondary to a mesenteric lipoma: a case report and review of the literature.

BACKGROUND: Small bowel volvulus is rare in adults and often has a precipitating factor. METHODS: This report describes a case of small bowel volvulus secondary to a mesenteric lipoma and reviews the literature describing this condition. CONCLUSION: Mesenteric lipoma is a rare precipitating cause of small bowel volvulus in adults. Computed tomography scanning may be useful for diagnosis preoperatively. The treatment of choice is surgery with complete excision of the lipoma.
