Application of ultrasound-guided endoscopic retrograde appendicitis therapy in children with appendix-related chronic abdominal pain / 中国当代儿科杂志

OBJECTIVES@#To study the clinical efficacy of ultrasound-guided endoscopic retrograde appendicitis therapy in children with appendix-related chronic abdominal pain.@*METHODS@#A retrospective analysis was performed on the medical data of 30 children with the chief complaint of chronic abdominal pain who were admitted from August 2019 to May 2021. All the children were found to have inflammation of the appendix or intracavitary stool and fecalith by ultrasound and underwent ultrasound-guided endoscopic retrograde appendicitis therapy. The medical data for analysis included clinical manifestations, endoscopic findings, white blood cell count, neutrophil percentage, length of hospital stay, and cure rate.@*RESULTS@#Among the 30 children with chronic abdominal pain, there were 13 boys (43%) and 17 girls (57%), with a mean age of (9±3) years (range 3-15 years) at diagnosis. The median duration of the disease was 12 months, and the median length of hospital stay was 3 days. The children had a median white blood cell count of 6.7×109/L and a neutrophil percentage of 50%±13%. Fecalith and a large amount of feces were flushed out of the appendix cavity for 21 children (70%) during surgery. The follow-up rate was 97% (29/30), and the median follow-up time was 11 months (range 5-26 months). Of the 29 children, abdominal pain completely disappeared in 27 children (93%).@*CONCLUSIONS@#Ultrasound-guided endoscopic retrograde appendicitis therapy is effective in children with chronic abdominal pain caused by feces or fecalith in the appendix cavity.

Effects of magnesium sulfate and dioctyl sodium sulfosuccinate on fecal hydration, output and systemic hydration in healthy horses / [Efeitos do sulfato de magnésio e do dioctil-sulfossuccinato de sódio na hidratação e eliminação fecal e sobre a hidratação sistêmica de cavalos saudáveis]

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)

Apendicolito: factor explícito que ocasiona apendicitis complicada en la niñez / Appendicolith: an explicit factor leading to complicated appendicitis in childhood

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

Effect of polyethylene glycol versus lactulose on abdominal pain in children occult constipation: a randomized controlled study: un estudio controlado aleatorio / Efecto del polietilenglicol versus lactulosa sobre el dolor abdominal en el estreñimiento oculto en niños

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.

Diferenciar la apendicitis con o sin fecalito ¿puede cambiar el enfoqueterapéutico?: Resultados preliminares / Differentiating between appendicitis with or without fecalith to change the therapeutic approach: Preliminary results

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.

Clinical Characteristics of Children Needing Inpatient Treatment after Failed Outpatient Treatment for Fecal Impaction / 대한소아소화기영양학회지

PURPOSE: Treatment of chronic constipation and fecal impaction is usually outpatient and requires high or frequent doses of laxatives. However, there are children who fail outpatient treatments, sometimes repeatedly, and are ultimately hospitalized. We sought to compare the characteristics of the children who failed outpatient treatment and needed inpatient treatment vs those who achieved success with outpatient treatment, in an effort to identify attributes that might be associated with a higher likelihood towards hospitalization. METHODS: In this retrospective cohort study, we reviewed the medical records of all patients aged 0 to 21 years, with chronic functional constipation and fecal impaction seen in the pediatric gastroenterology clinic over a period of 2 years. RESULTS: Total of 188 patients met inclusion criteria. While 69.2% were successfully treated outpatient (referred to as the outpatient group), 30.9% failed outpatient treatment and were hospitalized (referred to as the inpatient group). The characteristics of the inpatient group including age at onset of 3.6±3.6 years (p=0.02); black ethnicity (odds ratio [OR] 4.31, 95% confidence interval [95% CI] 2.04–9.09); p < 0.001); prematurity (OR 2.39, 95% CI 1.09–5.26; p=0.02]; developmental delay (OR 2.20, 95% CI 1.12–4.33; p=0.02); overflow incontinence (OR 2.26, 95% CI 1.12–4.53, p=0.02); picky eating habits (OR 2.02, 95% CI 1.00–4.08; p=0.04); number of ROME III criteria met: median 4, interquartile range 3–5 (p=0.04) and 13±13.7 constipation related prior encounters (p=0.001), were significantly different from the outpatient group. CONCLUSION: Identification of these characteristics may be helpful in anticipating challenges and potential barriers to effective outpatient treatment.

Acute Appendicitis in Children and Adolescents: Factors Associated with Perforation and the Causative Organism

PURPOSE: This study aimed to determine which factors are related to perforated appendicitis. We also conducted a survey to identify the causative organism. METHODS: From January 2011 to December 2014, 569 pediatric patients (322 male) younger than 19 years old who underwent an appendectomy due to acute appendicitis at Hallym University Sacred Heart Hospital were enrolled. Patients' medical records were reviewed retrospectively to determine their clinical manifestations, laboratory and imaging results, and pathogens. RESULTS: About 127 patients (22%) had perforated appendicitis. The rate of perforated appendicitis in preschool, late childhood, and adolescent ages were 50%, 27%, and 16.8%, respectively. The risk factors of perforation were high C-reactive protein levels and the presence of appendiceal fecalith (P <0.001). Of the 24 samples of peritoneal fluid and periappendiceal pus that were collected intraoperatively, 16 were culture positive. The most common pathogen was Escherichia coli (n=10), and others were Pseudomonas aeruginosa , Streptococcus spp., and Staphylococcus spp. CONCLUSIONS: The perforation rate of appendicitis among patients younger than 5 years old was 50%, and this decreased in proportion with age. Clinicians should be aware of the possibility of perforation when patients with appendicitis have high C-reactive protein levels or the presence of appendiceal fecalith on imaging.

Time Course of Treatment for Primary Enuresis With Overactive Bladder / 대한배뇨장애요실금학회지

PURPOSE: To characterize the course of treatment for nonmonosymptomatic enuresis with overactive bladder (OAB) in a real clinical setting. METHODS: Data from 111 OAB patients with moderate to severe enuresis were analyzed. The baseline analysis included a questionnaire, voiding diary, uroflowmetry with postvoid residual urine measurement, and plain abdominal radiography of the kidneys, ureters, and bladder (KUB). Following standard urotherapy for 1 month, anticholinergic medication was administered with or without laxatives. Desmopressin was added if there was a partial response to OAB. Patients were followed every 3 months to evaluate the status of OAB and enuresis. Multivariate analysis was performed to identify predictors associated with the lack of complete response (CR) in enuresis at 12 months. RESULTS: Following 12 months of treatment, 64% and 88% of patients experienced at least partial response in enuresis and OAB, respectively. Urgency improved more quickly than enuresis, supporting the need to address daytime symptoms before enuresis. Seventy-nine patients (71%) had fecal impaction on KUB and/or subjective constipation. The combination of anticholinergics with either laxatives or desmopressin fared better than anticholinergics alone. Daytime incontinence and anticholinergics-only treatment were associated with a lack of CR during 12 months of treatment. CONCLUSIONS: The data confirmed the validity of addressing OAB before treating enuresis. The results of this study also highlight the need to address fecal impaction. Patients should be counseled about the need for a prolonged course of treatment before starting treatment. Anticholinergics should be accompanied with either desmopressin or laxatives for better control of enuresis.

Bowel Perforation Due to Immobilization after Resurfacing Thumb with Anterolateral Thigh Free Flap in an Elderly Diabetic Woman

Inevitable immobilization after surgery on lower extremities can induce chronic constipation. Elderly diabetic women usually express ambiguous gastrointestinal symptoms and signs. We present here a case of panperitonitis developed from severe fecal impaction in an elderly diabetic woman after hand reconstruction using material harvested from the lower extremities. A 68-year-old diabetic female underwent anterolateral thigh free flap and wound revision twice on the left thumb. Three weeks after surgery, she complained about mild abdominal pain though she had daily defecation. Despite encouraging ambulation, her compliance was low. Resection of the sigmoid colon and colostomy were performed after diagnosis with bowel perforation. However, the patient went into septic shock and died with multiorgan failure after the guardians issued a DNR (do not resuscitate) order. For preventing bowel perforation, increased uptake of dietary fiber and early ambulation postoperatively should be encouraged, after even hand surgeries.

Reliability of barr, leech, and blethyn score in using of plain radiography in determining fecal impaction in children with and without constipation / Confiabilidade de pontuação dos escores de Barr, Leech e Blethyn no uso de radiografia simples na determinação da impactação fecal em crianças com e sem constipação

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.

Fístula cólon-jejunal em paciente com fecaloma e volvos jejunal e sigmoideano devido à dolicomegassigmoide: relato de caso / Colon fistula-jejunal in patient with fecaloma and volvos jejunal sigmoideano and due to dolicomegassigmoide: case report

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.

Single Stage Transanal Endorectal Pull-through Operation for Hirschsprung’s Disease in Neonate: A Single Center Experience / 소아외과

PURPOSE: The single stage transanal pull-through (SSPT) for Hirschsprung’s disease is becoming the most popular procedure. This single center study compared the result of single stage operation with two-stage operation for Hirschsprung’s disease in neonates. METHODS: We retrospectively reviewed medical records of all patients who were diagnosed as Hirschsprung’s disease and underwent SSPT or two-stage operation operation in Asan Medical Center between January 2003 and July 2014. RESULTS: There were 17 SSPT and 28 two-stage operation. The mean age of SSPT group was 14.2±7.1 days, and the mean age of two-stage operation group was 15.4±8.6 days for stomy formation, and 188.6±36.3 days for Duhamel operation. The operation time of SSPT was shorter than Duhamel operation (145.0±37.0 minutes vs. 193.0±36.0 minutes, p<0.001). The mean follow-up period of SSPT and two-stage operation was 35.5±34.9 months (range, 2-132 months) and 56.6±35.5 months (range, 1-121 months), respectively. Defecation problem rate such as fecal soiling or fecal impaction showed no significant difference between the two groups (p=0.719). Two SSPT patients required botulinum toxin injection due to rectal stenosis. Three patients of SSPT group underwent re-do endorectal pull-through due to remnant aganglionic or hypoganglionic bowel. CONCLUSION: The SSPT showed shorter hospital days. However, few patients experienced rectal stenosis, but were manageable with botulinum toxin injection. The SSPT requires experienced-pathologist, as well as surgeon, because intra-operation pathology reading is critical for appropriate SSPT. SSPT is a feasible and reasonable option to treat Hirschsprung’s disease.

Colonic transit in children and adolescents with chronic constipation / Trânsito intestinal em crianças e adolescentes com constipação crônica

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.

Local Management of Constipation: Enemas, Suppositories / 대한내과학회지

The treatment for constipation should be individualized and dependent on the cause, coexisting morbidities, and patient's cognitive status. Although most cases of constipation respond to conservative treatment, including dietary and life-style changes, or mild laxatives, some patients still complain of consistent symptoms and need an assessment of defecatory dysfunction. There is insufficient evidence to support the use of enemas in chronic constipation, although many clinicians and patients find them useful and effective for the treatment of fecal impaction when used with other modalities. In addition, suppositories can be considered as an initial trial for the treatment of defecatory dysfunction, since they help to initiate or facilitate rectal evacuation. The routine use of enemas is typically discouraged, especially sodium phosphate enemas, although tap-water enemas seem safe for more regular use. Soapsuds enemas are not recommended due to possible rectal mucosal damage.

Successful Removal of Hard Sigmoid Fecaloma Using Endoscopic Cola Injection / 대한소화기학회지

Colorectal fecaloma is hardening of feces into lumps of varying size that is much harder in consistency than a fecal impaction. Complications of colorectal fecaloma include ulceration, bleeding, perforation and obstruction of the colon. Most fecalomas are successfully removed by conservative treatment with laxatives, enemas and rectal evacuation to relieve fecal impaction. When conservative treatments have failed, a surgical intervention may be needed. Herein, we report a case of 4.7 cm sized sigmoid fecaloma showing no response to conservative treatments that was successfully removed by endoscopic fragmentation with Coca-Cola injection instead of surgery.

Ileal Fecaloma Presenting with Small Bowel Obstruction / 대한소아소화기영양학회지

A fecaloma refers to a mass of accumulated feces that is much harder than a mass associated with fecal impaction. Fecalomas are usually found in the rectosigmoid area. A 10-year-old male with chronic constipation was admitted because of increasing abdominal pain. An abdominal computed tomography scan and a simple abdominal x-ray revealed rapidly evolving mechanical obstruction in the small intestine. Most of the fecalomas are successfully treated by conservative methods such as laxatives, enemas and rectal evacuation. When conservative treatments have failed, surgical intervention may be needed. In this case, an emergency operation was performed and a 4x3x2.5 cm fecaloma was found in the distal ileum. We thus report a case of ileal fecaloma inducing small bowel obstruction in a patient with chronic constipation, who required surgical intervention. When symptoms of acute small intestinal obstruction develop in a patient with chronic constipation, a fecaloma should be considered in differential diagnosis.

Successful endoscopic treatment of fecalith blocking sinus in a patient with ileal pouch-anal anastomosis / Tratamento endoscópico bem-sucedido de fecálito bloqueando seio em paciente com anastomose bolsa ileal-anal

Background: Ulcerative colitis patients who underwent restorative proctocolectomy with ileal pouch-anal anastomosis can develop various mechanical complications. Among them is presacral sinus resulting from chronic anastomotic leak. Methods: We present a symptomatic patient with a large fecalith blocking the sinus which was successfully treated with Doppler ultrasound guided endoscopic needle knife sinusotomy along with fecalith extraction. Results: A 67-year-old female presented with a 4-month history of perianal pain and urgency. Pouchocopy showed a 3-cm deep wide-mouthed anastomotic sinus, the orifice of which was blocked by a large hard fecalith. Removal of the fecalith using RothNet, Tripod, or Basket were made but failed. Then needle knife was applied to cut the orifice to enlarge the opening of the sinus. One month later, the patient returned and the fecalith was successfully removed with two Baskets and two Rothnets. Six months after fecalith extraction, pouchoscopy showed a compartalized distal pouch sinus with two cavities, which was treated by two sessions of Doppler ultrasound guided endoscopic needle knife sinusotomy. Six months following the treatment, the sinus was completed healed. The patient tolerated all procedures well without any complication. Conclusion: Fecalith blocking pouch anastomotic sinus is a rare complication in patients with restorative proctocolectomy. In our case, this surgical complication was successfully treated with a carefully planned, stepwise endoscopy approach. (AU)

Experiênria: Pacientes com colite ulcerativa tratados por proctocolectomia restauradora com anastomose bolsa ileal-anal podem ser acometidos por diversas complicações mecânicas. Entre elas, cita-se o seio pré-sacral resultante de vazamento crônico pela anastomose. Métodos: Apresentamos uma paciente sintomática com um grande fecálito bloqueando o seio, com tratamento bem-sucedido com sinusotomia por bisturi-agulha guiado por ultrassom, juntamente com a extração do fecálito. Resultados: Mulher, 67 anos, apresentou-se com história de 4 meses de dor perianal e urgência. A avaliação endoscópica da bolsa ileal revelou um seio anastomótico com grande abertura situada a 3 cm de profundidade, cujo orifício estava bloqueado por um grande fecálito endurecido. Foi tentada sem sucesso a remoção do fecálito com a ajuda de Roth-Net, Tripod, ou cestos recuperadores. Depois dessas tentativas, aplicamos um bisturi-agulha com o objetivo de seccionar o orifício com vistas à ampliação da abertura do seio. Um mês depois, a paciente retornou, e o fecálito foi removido com sucesso com dois cestos recuperadores e dois RothNets. Transcorridos seis meses após a remoção do fecálito, uma avaliação endoscópica da bolsa ileal revelou um seio distal compartimentado com duas cavidades, tratado por duas sessões de sinusotomia endoscópica por bisturi-agulha guiado por ultrassom. Seis meses depois do tratamento, o seio estava completamente curado. A paciente tolerou satisfatoriamente todos os procedimentos, sem qualquer complicação. Conclusão: A presença de um fecálito bloqueando o seio anastomótico de bolsa ileal é complicação rara em pacientes submetidos a uma proctocolectomia restauradora. Em nosso caso, essa complicação cirúrgica foi tratada com sucesso com uma abordagem endoscópica em etapas, cuidadosamente planejada. (AU)

Constipação intestinal / Constipation

A constipação intestinal acomete cerca de 20% da população mundial e constitui um dos sintomas mais frequentes de procura ao médico. É mais comum em mulheres e idosos e se encontra entre as doenças funcionais do intestino. Pode ser referida pelo paciente como fezes endurecidas, esforço excessivo no ato evacuatório, evacuações infrequentes ou sensação de evacuação incompleta. Subdivide-se em primária e secundária, tendo essa última causa bem definida, como doenças endócrinas e neurológicas ou uso inadvertido de substâncias obstipantes. É importante orientarmos nossos pacientes para a necessidade de uma dieta rica em fibras e de uma hidratação adequada. O manejo farmacológico pode incluir suplementação de fibras, laxativos osmóticos, emolientes e laxativos irritativos

Constipation occurs in about 20% of the world population and it is a common reason for seeking medical attention. It is more common in women and in the elderly and may be part of a generalized gastrointestinal dysmotility syndrome. Patients may define constipation as hard stools, excessive straining, infrequent stools, or a sense of incomplete evacuation. There are two main types of constipation - primary or secondary, the latter caused by systemic disorders such as endocrine disorders, neurologic dysfunction, or as a side effect of medications. Proper dietary fiber and fluid intake should be emphasized. Pharmacologic management of constipation may include fiber laxatives, osmotic laxatives, stool surfactants, or stimulant laxatives
