RESUMEN

Magnesium sulphate (MS) and dioctyl sodium sulphosuccinate (DSS) are laxative drugs frequently used for the treatment of impactions. The aim of this study was to compare the effects of MS and DSS in fecal hydration, output and systemic hydration in healthy horses. Five healthy horses received 3 treatments with a 21-day interval. Treatment 1 was performed with administration of 4 liters of warm water; treatment 2: administration of 4 liters of warm water associated with 1g/kg of MS; and treatment 3: administration of 4 liters of warm water associated with 20mg/kg DSS. General and specific physical examination of the digestive system were performed, alongside with packed cell volume and total plasma protein measurement, abdominal ultrasonography and quantification of the amount and hydration of feces, before and 6, 12, 24, 36 and 48 hours after the treatments. No adverse effects were observed. The administration of laxatives promoted greater fecal output and hydration without resulting in systemic dehydration, yet no differences were observed between treatments. The absence of adverse effects of DSS demonstrates the safety of its use as a laxative drug at a dose of 20mg/kg. Studies comparing the effects of the laxative drugs in horses with large colon impaction are needed.(AU)

O sulfato de magnésio (SM) e o dioctil-sulfossuccinato de sódio (DSS) são drogas laxativas frequentemente utilizadas no tratamento da compactação. O objetivo deste estudo foi comparar os efeitos do SM e do DSS na hidratação e eliminação fecal, e na hidratação sistêmica de cavalos saudáveis. Cinco cavalos receberam três tratamentos, com intervalo de 21 dias. O tratamento 1 consistiu na administração de quatro litros de água morna; o tratamento 2: administração de quatro litros de água morna associada a 1g/kg de SM; e o tratamento 3: administração de quatro litros de água morna associada a 20mg/kg de DSS. Foram realizados exames físicos gerais e específicos do trato digestivo, hematócrito e proteína plasmática total, ultrassonografia abdominal e mensuração da quantidade e hidratação das fezes antes e após seis, 12, 24, 36 e 48 horas dos tratamentos. Não foram observados efeitos adversos. A administração de ambos os laxantes promoveu maior produção fecal e hidratação, sem resultar em desidratação sistêmica, entretanto não houve diferença entre os tratamentos. A ausência de efeitos adversos do DSS demonstra a segurança de seu uso como medicamento laxante na dose de 20mg/kg. São necessários estudos que comparem o efeito dos laxantes em equinos portadores de compactação de cólon.(AU)

RESUMEN

Objetivos. El objetivo de este estudio fue evaluar el riesgo clínico de la apendicitis con apendicolito y su importancia al elegir las estrategias terapéuticas.Métodos. Se analizó retrospectivamente a niños con diagnóstico de apendicitis aguda entre junio de 2011 y enero de 2017. Se dividió en un grupo con apendicolito(GA) y un grupo sin apendicolito (GSA) según la presencia o no de apendicolito durante la cirugía abierta. Se revisaron y compararon la presentación clínica, de laboratorios, los resultados de la tomografía computada y los cambios patológicos.Resultados. De 163 pacientes, se incluyó a 23 (media de edad: 6,1 años) en el GA y a 140 (media de edad: 8,1 años) en el GSA. Los pacientes en el GA tuvieron una hospitalización más extensa, mayor temperatura corporal, mayor frecuencia de diarrea, signo de Blumberg, aumento del porcentaje de neutrófilos, proteína C-reactiva y mayor riesgo de perforación. La puntuación en las escalas de Alvarado (8,3 ± 1,2 frente a 7,0 ± 1,3; P < 0,05) y de respuesta inflamatoria a apendicitis (10,7 ± 1,6 frente a 7,7 ± 1,9; P < 0,05) fue mayor en el GA que en el GSA; la presencia de fiebre y apendicolito se asoció con una mayor tasa de apendicitis perforada.Conclusiones. La apendicitis pediátrica con apendicolito representa un mayor riesgo clínico y tiende a causar apendicitis complicada

Objectives. This study aims to assess the clinical risk of pediatric appendicitis with appendicolith and its guiding significance in therapeutic strategies' selection.Methods. Children diagnosed with acute appendicitis from June 2011-January 2017 were analyzed retrospectively. Patient cohort was divided to appendicolith group (AG) and non- appendicolith group (NAG) based on whether the appendicolith presents or not in the open surgery. Clinical presentations, laboratory parameters, computed tomography findings, and pathological changes were reviewed and compared between two groups. Results. Among 163 patients, 23 (meanage,6.1yearsold)weredefinedin AG and 140; mean age, 8.1 years old) in NAG. The patients in AG demonstrated prolonged length of stay (12.4 ± 5.6d vs. 8.7 ± 5.0d, P <0.05), higher body temperature (38.2 ± 0.8 °C vs. 37.3 ± 0.8 °C, P <0.05), higher frequency of diarrhea (17 % vs. 3%, P <0.05), rebound tenderness (100 % vs. 87 %, P <0.05), increased neutrophil percentage (81.4 ± 8.0 % vs. 65.3 ± 22.8 %, P <0.05), C-reactive protein (33.13 ± 10.3 mg/L vs. 23.7 ± 13.7 mg/L, P <0.05), and great risk of perforation (78 % vs. 29 %, P <0.05). Alvarado score (8.3 ± 1.2 vs. 7.0 ± 1.3, P <0.05) and AIR score (10.7 ± 1.6 vs. 7.7 ± 1.9, P <0.05) of AG, were higher than NAG he presence of fever and appendicolith was associated with a high rate of perforated appendicitis.Conclusions. Pediatric appendicitis with appendicolith has greater clinical risk and tends to causing complicated appendicitis

RESUMEN

INTRODUCTION AND AIM: Abdominal pain in children is a frequent cause of emergency room consultation. An important group of those patients presents with chronic constipation and fecal impaction. Plain abdominal x-ray is widely used for making a diagnosis and ruling out the need for surgical treatment. The present study examined the association between pain intensity and fecal impaction grade. MATERIALS AND METHODS: An analytic cross-sectional study was conducted that compared 2 radiographic scales to determine the association between the grade of fecal impaction observed and abdominal pain intensity in patients that sought medical attention at an emergency service within a 7-month period. The analysis was carried out by 2 different observers, utilizing 2 different radiographic scales to confirm their reproducibility. The degree of interobserver agreement was measured using the Kappa coefficient and the association between abdominal pain and fecal impaction grade was measured through the Spearman correlation coefficient. RESULTS: There was a significant association between pain intensity and the radiographic grade of fecal impaction (P<.05) for the radiographic scale by segments and its interobserver agreement was high, compared with the scale by percentage. CONCLUSIONS: Radiographic scales may be useful in the evaluation and treatment of patients with abdominal pain and constipation. The segmental scale showed less interobserver variability, suggesting its proposal as an alternative in the evaluation and follow-up of patients with chronic constipation.

RESUMEN

The puma (Puma concolor) is a large felid native to the Americas and one of the endangered species of the Brazilian fauna. Digestive disorders such as fecalomas are common in veterinary practice. Fecalomas are masses of retained feces that accumulate in the large colon and progress to hard fecal concretions that are difficult and painful to expel. Inadequate diets and mechanical intraluminal or extraluminal intestinal obstructions are the major causes of fecaloma. Tenesmus, anorexia, vomiting and dehydration are common clinical signs. The diagnosis is based on medical history and physical examination, and can be confirmed by imaging assessment. Fecalomas are amenable to conservative and surgical treatment, depending on disease severity. This paper describes a case of fecaloma in a puma. The diagnosis was made during exploratory laparotomy and improper diet incriminated as the cause. Surgical intervention consisted of enterotomy followed by removal hardened retained feces. Postoperative dietary management consisted of a liquid follow by a soft diet, with reintroduction of the regular diet after full recovery. Dietary supplementation with vegetable fibers was prescribed for life to prevent recurrence.

O puma (Puma concolor), também conhecido como onça-parda ou suçuarana, é um grande felídeo carnívoro exclusivo das Américas, e uma das espécies da fauna brasileira ameaçadas de extinção. As alterações do sistema digestório são comuns na prática clínica veterinária e dentre essas se encontram os fecalomas, massas de fezes retidas no cólon que se tornam concreções fecais difíceis e dolorosas de expulsar. As principais causas são dietas inadequadas, bem como distúrbios de pelve associados à osteopatias metabólicas ou traumas. Os sinais clínicos são tenesmo, anorexia, vômitos e desidratação. O diagnóstico é baseado em anamnese e exame físico, sendo confirmado por exames de imagem. O tratamento pode ser médico ou cirúrgico, dependendo da apresentação clínica. Este artigo relata o caso de um puma que apresentou fecalomas em função de dieta inadequada, sendo que o diagnóstico foi feito por meio de laparotomia exploratória. O ato cirúrgico progrediu para realização de enterotomia e remoção das fezes retidas, que se apresentaram bastante endurecidas. Após a cirurgia, o paciente recebeu dieta líquida e posteriormente pastosa, e apresentou recuperação completa. Para prevenção de recidivas indicou-se correção dietética com adição permanente de fibras vegetais à alimentação.

RESUMEN

Introduction and aim: Functional abdominal pain (FAP) is one of the major gastrointestinal complaints in childhood. Studies have reported occult constipation (OC) as one of the leading causes of abdominal pain. Recent researches have proposed laxatives as potent therapeutic targets for abdominal pain in patients with OC. However, no study has compared effect of poly ethylene glycol (PEG) and lactulose on occult constipation. Materials and methods: 51 patients aged 4 to 18 years with abdominal pain who had OC (defined as fecal impaction in abdominal X ray) were studied. Demographic and clinical data including age, sex, body weight, height, abdominal pain duration, abdominal pain rate and fecal odor were registered. They were randomly assigned to receive PEG (1gr/kg) or Lactulose (1cc/kg) for at least two weeks. All patients were reevaluated by pain measurement scale after at least two weeks of treatment. Results: It is indicated that the efficacy of PEG for reducing abdominal pain in OC was 48% while it was 37% for Lactulose. This study indicated that this efficacy is not affected significantly by sex and fecal odor, however this efficacy is influenced by age, body weight, abdominal pain duration and abdominal pain rate for both PEG and Lactulose. Conclusion: It could be concluded that PEG is a more efficient drug for treating abdominal pain in occult constipation than Lactulose and its optimum effect can be achieved in elder patients with more severe abdominal pain.

Introducción y objetivo: El dolor abdominal funcional (FAP) es una de las principales molestias gastrointestinales en la infancia. Los estudios han informado que el estreñimiento oculto (OC) es una de las principales causas de dolor abdominal. Investigaciones recientes han propuesto laxantes como objetivos terapéuticos potentes para el dolor abdominal en pacientes con OC. Sin embargo, ningún estudio ha comparado el efecto del polietilenglicol (PEG) y la lactulosa sobre el estreñimiento oculto. Materiales y métodos: Se estudiaron 51 pacientes de 4 a 18 años con dolor abdominal que tenían OC (definida como impactación fecal en rayos X abdominales). Se registraron datos demográficos y clínicos que incluyen edad, sexo, peso corporal, altura, duración del dolor abdominal, tasa de dolor abdominal y olor fecal. Fueron asignados aleatoriamente para recibir PEG (1 gr/kg) o lactulosa (1 cc/kg) durante al menos dos semanas. Todos los pacientes fueron reevaluados por la escala de medición del dolor después de al menos dos semanas de tratamiento. Resultados: Se indica que la eficacia de PEG para reducir el dolor abdominal en OC fue del 48% mientras que fue del 37% para la lactulosa. Este estudio indicó que esta eficacia no se ve afectada significativamente por el sexo y el olor fecal, sin embargo, esta eficacia está influenciada por la edad, el peso corporal, la duración del dolor abdominal y la tasa de dolor abdominal tanto para PEG como para lactulosa. Conclusión: Se podría concluir que el PEG es un fármaco más eficaz para tratar el dolor abdominal en el estreñimiento oculto que la lactulosa y que su efecto óptimo se puede lograr en pacientes mayores con dolor abdominal más severo.Palabras clave: dolor abdominal, estreñimiento oculto, polietilenglicol, lactulosa.

RESUMEN

The ingestion of detritus by sea turtles results in high mortality and morbidity. The objective of this study was to describe the characteristics of free-living sea turtles that ingested anthropogenic inorganic detritus in comparison to those that did not. A total of 186 necropsy files were analyzed in marine turtles from the beaches of the Microregion dos Lagos, Rio de Janeiro. Among the turtles that ingested detritus, the mean turtle was female and cachectic, with a carapace length of 36,6 cm, detritus accumulated in the large intestine, and fecal compaction. It seems most likely that's low food transit, combined with the multiplicity of ingestion, favored the accumulation of detritus. This ingestion resulted in cachexia associated with fecal compaction, since the greatest accumulation was in the large intestine. The intake of detritus by turtles was not punctual but continuous. These studies demonstrated the vulnerability of these animals to environmental pollution.

RESUMEN

Antecedentes: el manejo de los pacientes con apendicitis aguda fue clásicamente quirúrgico. En la era de los antibióticos se plantean nuevos paradigmas terapéuticos. La diferencia en el origen de la apendicitis podría establecer el tratamiento por elegir. Objetivo: analizar si la presencia de fecalito en una apendicitis puede condicionar un tratamiento quirúrgico o solo con antibióticos. Material y métodos: análisis descriptivo observacional de las diferencias intraoperatorias y anatomopatológicas de los pacientes operados por apendicitis aguda, divididos en 2 grupos según presentaran fecalito o hiperplasia linfoidea como causa de origen. Se utilizó la prueba de Chi2 para la comparación de ambos grupos, tomando un valor de p<0,05. Resultados: el grupo de apendicitis por fecalito presentó un estadio más avanzado de la enfermedad, con líquido libre con más frecuencia (el 67% de los pacientes con apendicitis aguda por fecalito vs. el 18% en el grupo de apendicitis aguda por hiperplasia), en más de una localización (solo el grupo con fecalito presentó líquido en el fondo de saco de Douglas o en el resto del abdomen, en el 50% y 16,7% respectivamente), con características que variaron entre seroso y purulento y anatomopatológicamente presentaron mayor afectación de las capas histológicas (en el grupo hiperplasia la afectación hasta la mucosa fue 63,6% vs. 16,7%, mientras que en el grupo fecalito fue más frecuente la afectación hasta la serosa 66,6% vs. 27,3%). Conclusiones: los pacientes con apendicitis aguda por hiperplasia linfoidea tendrían menos complicaciones intraabdominales en el posoperatorio y podrían ser buenos candidatos a tratamiento médico solo con antibióticos, evitando la cirugía.

Background: Surgery is the traditional approach for patients with acute appendicitis. In the antibiotic era, new therapeutic paradigms are being proposed. The difference in the cause of appendicitis could establish the treatment of choice. Objective: to analyze if the presence of fecalith in an appendicitis can condition a surgical treatment or only with antibiotics. Material and methods: This observational analysis describes the intraoperative and pathological differences between patients undergoing surgery for acute appendicitis, divided into two groups according to the presence of fecalith or lymphoid hyperplasia as cause of the condition. The chi square test was used to compare the fecalith group versus the lymphoid hyperplasia group using a p value < 0.05. Results: The presence of fecaliths was more commonly associated with advanced stage of inflammation, presence of free peritoneal fluid (67% vs. 18% in the lymphoid hyperlasia group) and in more than one site (50% in the Douglas' pouch and 16.7% in the rest of the abdominal cavity). In this group, peritoneal fluid varied between serous and purulent and more appendiceal layers were involved (63.6% of mucous layer involvement in the lymphoid hyperplasia group vs. 16.7%, while serous compromise was more common in the fecalith group: 66.6% vs. 27.3%). Conclusions: Patients with acute appendicitis due to lymphoid hyperplasia could have lower rate of post-operative complications or could be good candidates for medical treatment with antibiotics alone, avoiding surgery.

RESUMEN

A compactação de íleo tem como principal etiologia a ingestão de alimentos grosseiros, com um alto teor de fibra, mas podem ocorrer em casos de infestação parasitária intensa; porém, a obstrução do íleo é considerada uma afecção rara em potros neonatais. O objetivo deste trabalho é relatar um caso de compactação de íleo causado pela ingestão acidental de casca de arroz, que acabou associada a um quadro agudo de síndrome cólica, em uma potra neonato com 4 dias de nascida da raça Quarto de Milha. O diagnóstico definitivo foi realizado através das alterações macroscópicas observadas durante a necrópsia. Apesar de não ser uma afecção comum, a compactação de íleo por ingestão de casca de arroz deve ser levada em consideração, principalmente em animais neonatos submetidos ao manejo de baia após o nascimento, visto que não é responsiva aos tratamentos convencionais dependendo da quantidade ingerida, sendo recomendado o encaminhamento cirúrgico.

The ileal impaction has as main etiology the ingestion of coarse foods, with a high fiber content but may occur in cases of intense parasitic infestation; however, an obstruction of the ileum is considered a rare condition in neonatal foals. The objective of this study is to report a case of ileal impaction caused by the accidental ingestion of rice hulls, which ended up associated with an acute colic syndrome, in a quarter horse, newborn filly with 4 days of birth. The definitive diagnosis was made through the macroscopic changes observed during the necropsy. Although it is not a common condition, ileal impaction by ingestion of rice hulls should be considered critical, especially in neonates submitted to stall management after birth, since it is not responsive to conventional treatments depending on the amount ingested, surgical referral is recommended.

RESUMEN

BACKGROUND: The appendix inflammatory process is the most common cause of chronic abdominal pain in the right lower quadrant. The frequency of appendiceal lumen obstruction by fecalith ranges from 10 to 20%; few cases of obstruction by multiple fecaliths had been reported. CLINICAL CASE: Sixty-nine years old male, diabetic and hypertensive in control, he underwent bowel resection 30 years previously. He completed 6 months with intermittent, mild pain in the right lower quadrant abdomen; 14 days prior to admission with increasing pain, nausea, vomiting, constipation, abdominal distension and absence of peristalsis; 12,750 leukocytes, neutrophils 90%; plain abdominal radiography without specific bowel pattern, TAC with 3 dense images in right lower quadrant; exploratory laparotomy was performed and perforated appendix with 3 free fecaliths was found. Histopathological report showed fibrosis and lymphocytic infiltrate in the muscle layer of the cecal appendix consistent with chronic appendicitis. CONCLUSIONS: The most common obstruction of the appendix lumen is by a single fecalith. In this case the patient had chronic appendicitis secondary to appendiceal lumen obstruction by multiple fecaliths. Reviewing the international literature any case of chronic appendicitis associated with the presence of multiple fecaliths was found.

RESUMEN

ABSTRACT Background - Several scoring was developed for evaluation of children with fecal retention using plain radiograph. There are controversies about specificity and sensitivity of these scoring system. Objectives - The aim of this study was to evaluate Barr, Blethyn, and Leech score in evaluation of fecal load in plain radiograph. Methods - This case control study was conducted on children aged 2-14 years old with abdominal pain who visited Abuzar children's Hospital of Ahvaz University of Medical Sciences. This study was conducted in fall season. Children with history of previous abdominal surgery, any systemic illness including sickle cell anemia were excluded. Children with constipation were placed in case group. Subjects without constipation were placed in control group. Subjects without exclusion criteria were examined by physician who is blind to aim of the study. Careful history and physical examination was done. Demographic features, history of gastrointestinal problem, duration of abdominal pain, defecation habit, stool consistency (loose, hard), and results of physical examination were recorded. Rome III criteria was used for definition of constipation. Abdominal x-ray was ordered for each patients. Abdominal radiography was reviewed by radiologist. Barr, Leach, and Blethyn scores were calculated for each case. Results - In this study 102 children with functional constipation and 102 children without constipation as a control were included. Mean ±SD for case and control group was 68.39±34.88 and 69.46±32.60 (P=0.82).Leech score (mean ±SD) was 11.05±2.177 and 5.67±3.228 for case and control group respectively (P<0.0001). Barr score (mean ±SD) was 14.86±3.54 and 7.16±5.59 for case and control group respectively (P=<0.0001). Blethyn (mean ±SD) score was 1.97±0.667 and 1.04±0.900 for case and control group respectively (P=0.000). Sensitivity and specificity of Barr score was 83% and 79% respectively. Sensitivity and specificity of Leech score was 92% and 80% respectively. Sensitivity and specificity of Blethyn score was 79% and 92% respectively. Conclusion - Barr, Blethyn and Leech scores were significantly higher in children with abdominal pain and constipation in contrast to children with abdominal pain and without constipation. Sensitivity of Leech score was more than Barr and Blethyn scoring systems. Specificity of Blethyn score was more than Barr and Leech score.

RESUMO Contexto - Diversos métodos de pontuação utilizando a radiografia simples foram desenvolvidos para a avaliação de retenção fecal em crianças. Há controvérsias sobre a especificidade e sensibilidade destes sistemas de pontuação. Objetivo - O objetivo deste estudo foi avaliar os sistemas de escore Barr, Blethyn e Leech na avaliação do conteúdo fecal pela radiografia simples. Métodos - Estudo de caso controle em crianças com idade entre 2-14 anos, com dor abdominal que consultaram o Abuzar children's Hospital of Ahvaz University of Medical Sciences, durante o outono. Crianças com história prévia de cirurgia abdominal, com qualquer doença sistêmica, incluindo anemia falciforme, foram excluídas. Crianças com constipação foram inseridas no estudo e crianças sem constipação inseridas no grupo controle. Pacientes sem critérios de exclusão foram examinados por médico que ignorava o objeto do estudo. Foram realizadas história clínica e exame físico cuidadosos. Foram registradas as características demográficas, a história do problema gastrointestinal, a duração da dor abdominal, os hábitos intestinais e evacuatórios, a consistência das fezes (duras, amolecidas), e os resultados do exame físico. Os Critérios de Roma III foram usados para a definição de constipação. Radiografia simples do abdômen foi ordenada para cada paciente. Foram calculados os escores de Baar, Leech e Blethyn para cada paciente. Resultados - Foram incluídas neste estudo 102 crianças com constipação funcional e 102 crianças sem constipação como controle. A idade média com desvio padrão para o grupo paciente foi de 68.39±34.88 e de 69.46±32.60 para o grupo controle (P=0.82). O escore de Leech (média ±DP) foi de 11.05±2.1777 para pacientes e de 5.67±3.228 para o grupo controle (P<0.0001). A pontuação de Barr (média ± DP) foi 14.86±3.54 para pacientes e de 7.16±5.59 para o grupo controle (P=<0.0001). O escore Blethyn (média ±DP) foi de 1.97±0.667 para pacientes e de 1.04±0.900 para o grupo controle (P=0.000). A sensibilidade e especificidade para o escore de Baar foi de 83% e 79% respectivamente. Para o escore de Leech foi de 92% de sensibilidade e 80% de especificidade. O escore de Blethyn resultou em 79% de sensibilidade e especificidade de 92%. Conclusão - As pontuações de Baar, Blethyn e Leech foram significativamente maiores em crianças com dor abdominal e constipação em contraste com as crianças com dor abdominal e sem constipação. A sensibilidade de pontuação Leech foi maior do que os sistemas de pontuação Barr e Blethyn. Escore de Blethyn teve mais especificidade que as pontuações Barr e Leech.

Barr, Leach, and Blethyn scores were calculated for each case. RESULTS: - In this study 102 children with functional constipation and 102 children without constipation as a control were included. Mean ±SD for case and control group was 68.39±34.88 and 69.46±32.60 (P=0.82).Leech score (mean ±SD) was 11.05±2.177 and 5.67±3.228 for case and control group respectively (P<0.0001). Barr score (mean ±SD) was 14.86±3.54 and 7.16±5.59 for case and control group respectively (P=<0.0001). Blethyn (mean ±SD) score was 1.97±0.667 and 1.04±0.900 for case and control group respectively (P=0.000). Sensitivity and specificity of Barr score was 83% and 79% respectively. Sensitivity and specificity of Leech score was 92% and 80% respectively. Sensitivity and specificity of Blethyn score was 79% and 92% respectively. CONCLUSION: - Barr, Blethyn and Leech scores were significantly higher in children with abdominal pain and constipation in contrast to children with abdominal pain and without constipation. Sensitivity of Leech score was more than Barr and Blethyn scoring systems. Specificity of Blethyn score was more than Barr and Leech score.

RESUMEN

O dolicomegacólon consiste no aumento do comprimento e diâmetro dos segmentos do cólon, causando alteração da motilidade e interferindo no funcionamento do trânsito intestinal. Pode ser classificado em: Aganglionose Congênita ou Doença de Hirschsprung; o Megacólon Chagásico ou Adquirido e o Idiopático. Suas principais complicações são fecalomas, volvos, úlceras por estase fecal com isquemia da parede intestinal e perfurações. Relatamos o caso de uma paciente com quadros recorrentes de suboclusões intestinais que melhoravam com tratamentos clínicos conservadores. Os preparos mecânicos para realização de uma colonoscopia sempre foram inadequados devidos aos fecalomas, volvo sigmoideano e a dor forte apresentada pela paciente durante tais tentativas. Indicado laparotomia exploradora, evidenciou-se volvo de sigmoide com fecaloma impactado, aderido e fistulizado para um volvo de jejuno distal.

The dolicomegacólon is to increase the length and diameter of the parts of the colon, causing changes in motility and interfering with the operation of the intestinal transit. Can be classified into: Aganglionosis Congenital or Hirschsprung disease; the Chagas Disease or Acquired megacolon and idiopathic. Its main complications are fecalomas, volvulus, fecal stasis ulcers with ischemia of the bowel wall and perfurações. We report the case of a patient with recurrent episodes of intestinal sub-occlusion that improved with conservative medical treatment. Mechanical preparation for performing a colonoscopy were always inadequate due to fecalomas, sigmoideano volvo and severe pain presented by the patient during such attempts. Suitable exploratory laparotomy, revealed a sigmoid volvulus with impacted fecal impaction, and joined fistulized for volvo distal jejunum.

RESUMEN

BACKGROUND: Acute appendicitis and acute cholecystitis are among the most common diagnoses that general surgeons operate on. However, it is rarely described in its synchronous form. CLINICAL CASE: A 43 year-old woman attending the clinic for right upper quadrant pain of 11 days duration. The patient refers to intermittent radiating pain in the right side, with positive Murphy, tachycardia, and fever. The laboratory results showed white cells 16,200/mm(3), glucose 345 mg/dl, abnormal liver function tests. Acute cholecystitis was reported with ultrasound. A Masson-type incision was made, noting an enlarged pyogenic gallbladder with thickened walls, sub-hepatic abscess of approximately 300 ml, greenish-yellow colour, and foetid. An anterograde subtotal cholecystectomy is performed due to difficulty in identifying elements of Calot triangle due to the inflammatory process, opening it and extracting stones. The right iliac fossa is reviewed, finding a plastron and a sub-serous retrocaecal appendix perforated in its middle third with free fecalith and an abscess in the pelvic cavity. An anterograde appendectomy was performed and the patient progressed satisfactorily, later being discharged due to improvement. DISCUSSION: In this patient, with a history of recurrent episodes of gallbladder pain and disseminated acute abdominal pain without peritoneal irritation, clinical suspicion was exacerbated cholecystitis with probable empyema of the gallbladder. Open surgery approach for this patient allowed access to both the appendix and gallbladder in order to perform a complete exploration of the abdominal cavity. CONCLUSION: The synchronous presentation of cholecystolithiasis and complicated appendicitis has not been reported in the literature.

RESUMEN

OBJECTIVE: The aim of this study was to assess clinical features and colonic transit patterns in Brazilian children with refractory constipation.METHODS: From 2010 to 2013, 79 constipated patients received follow-up care in a tertiary hospital. Of these patients, 28 (aged 8-14 years) were refractory to conventional therapy and underwent a simplified visual method of nuclear colonic transit study, by ingestion of a liquid meal containing 9.25 MBq/kg of 99mTc-phytate. Abdominal static images were taken immediately and at two, six, 24, 30, and 48 h after ingestion for qualitative analysis of the radio marker progression through the colon.RESULTS: Two patterns of colonic transit were found: slow colonic transit (SCT,n = 14), when images at 48 h showed a larger part of the tracer remained in proximal and transverse colon, and distal retention (DR, n = 14), when after 30 h, the radio isotope passed the transverse colon and was retained in the rectosigmoid up to 48 h. The SCT and DR group included, respectively, nine and ten males; median ages in the nuclear study of 11 and 10 years, p = 0.207; median duration of constipation of seven and six years, p = 0.599. Constipation appearing during first year age (p = 0.04) and report of soft stools (p = 0.02) were more common in SCT patients. Palpable abdominal fecal impaction was found only in DR group. Appendicostomy for antegrade continence enema was successful in 4/12 (30%) of SCT patients (median follow-up: 2.4 years).CONCLUSION: Nuclear transit study distinguished two colonic dysmotility patterns and was useful for guiding refractory patients to specific therapies.

OBJETIVO: Avaliar as características clínicas e os padrões de trânsito intestinal em crianças brasileiras com constipação refratária.MÉTODOS: De 2010 a 2013, 79 pacientes constipados receberam acompanhamento em um hospital terciário. Desses pacientes, 28 (entre 8-14 anos) foram identificados como terapia refratária a convencional e passaram por um método visual simplificado de estudo nuclear do trânsito intestinal, com ingestão de uma refeição líquida contendo 9,25 MBq/Kg de fitato-99mTc. Imagens estáticas abdominais foram tiradas imediatamente e em duas, seis, 24, 30 e 48 horas após a ingestão para uma análise qualitativa da progressão do marcador radioativo pelo cólon.RESULTADOS: Foram encontrados dois padrões de trânsito intestinal: trânsito intestinal lento (STC, n = 14), quando as imagens de 48 horas mostraram que grande parte do marcador permaneceu no cólon proximal e transversal; e retenção distal (DR, n = 14), quando, após 30 horas, o radioisótopo havia passado o cólon transverso e estava retido no retossigmoide até 48 horas. O grupo STC e o grupo DR incluíram, respectivamente, nove e 10 meninos; idade média no momento do NTS: 11 e 10 anos, p = 0,207; duração média de constipação: sete e seis anos, p = 0,599. Sintomas de constipação durante o primeiro ano de idade (p = 0,04) e relatos de fezes moles (p = 0,02) foram mais comuns em pacientes com STC. Observou-se impactação fecal abdominal palpável apenas no grupo DR. A apendicostomia para enema anterógrado para continência foi bem-sucedida em 4/12 (305) pacientes com STC (acompanhamento médio: 2,4 anos).CONCLUSÃO: O estudo nuclear do trânsito diferenciou dois padrões de dismotilidade intestinal e foi útil para orientar pacientes refratários a terapias específicas.
