ABSTRACT
Chronic intestinal pseudo-obstruction (CIPO) is caused by a plethora of primary and secondary causes, dominantly involving the neuromuscular tissue, interstitial cells of Cajal, or the connective tissue framework. The lack of the connective tissue framework, known as desmosis, is evaluated by Masson's trichrome (MT) or picrosirius red stains, both of which are recommended in the London classification. We evaluated the orcein stain in detecting desmosis in comparison to the MT stain. We performed both orcein and MT stains in six previously published cases of complete or partial desmosis along with six age-matched controls. Our results showed comparable results of the orcein stain as compared to the MT stain. Additional advantages of lower cost and a clearer background in orcein stain were noteworthy, whereas MT stain can be used for the detection of additional pathology. We believe that orcein stain can be used as a cheap alternative in resource-limited settings.
ABSTRACT
Introduction: Chronic intestinal constipation (CIC) presents an incidence of 2.6 to 30.7% in the overall population and due to the social reality imposed by the coronavirus pandemic, some behavior changes in the Brazilian population occurred that might or not be associated with alterations of CIC prevalence. Objective: To assess CIC incidence in medical students before and during the COVID-19 pandemic in Brazil in a private higher educational institution in the city of São Paulo, state of São Paulo. Methods: Clinic data were collected through Google Forms software from the same students seeking to analyze the variables before (year of 2019) and during the coronavirus pandemic. The data were: age, sex, body mass index, constipation referred in a subjective way and confirmed through the ROME III criteria, feces consistency and anxiety and/or depression during the pandemic. Results: A total of 126 medical students from a private higher education institution from São Paulo, SP were included. The average age was 22.9 years old, 70.6% were female and the average BMI was 23.3 kg/m2. Regarding the ROME III criteria, 32.5% presented >2 in 2019 and 42.1% during the pandemic. Concerning the feces consistency, 31.75 and 35.71% presented dry Bristol 1 feces or in both periods, respectively. Conclusion: It was observed an increase in the prevalence of chronic intestinal constipation in medical students from a private higher education institution from São Paulo, state of São Paulo, during the COVID-19 pandemic, as well as dryness in the feces.

Chronic intestinal failure represents a long-lasting condition of intestinal dysfunction that contributes to inadequate absorption of macronutrients and/or water and electrolytes. It is heterogeneous in clinical manifestation, intervention and prognosis, and usually requires multi-disciplinary management. This review elucidates the state-of-the-art consensus on diagnosis and definition in chronic intestinal failure and exemplifies relevant nutritional management principles with interventions in short bowel syndrome, in hopes of improving the identification and management of chronic intestinal failure in domestic practice.
ABSTRACT
Resumen: La falla intestinal crónica (FIC) o tipo III es una condición invalidante, y la nutrición parenteral crónica (NPC) domiciliaria es el tratamiento que permite a estos pacientes mantenerse con vida. Sin embargo, solamente uno de cada tres países latinoamericanos cuentan con ese recurso, y sus complicaciones no son infrecuentes. Estas complicaciones son las principales indicaciones para trasplante intestinal, un procedimiento que en la mayoría de los países de ingresos medios no se ha desarrollado y no ha presentado los resultados esperados. En los últimos años, la rehabilitación intestinal a nivel mundial ha mejorado sustancialmente con el uso de análogos semisintéticos del péptido 2 similares al glucagón, existiendo cada vez mayor evidencia que demuestra la posibilidad de rehabilitación intestinal e independencia de la NPC con este fármaco, incluso en pacientes con anatomía desfavorable. Estos resultados han permitido mejorar la supervivencia y la calidad de vida de pacientes con FIC y, en muchas ocasiones, prescindir del trasplante. El paciente del caso que presentamos es el primero en recibir esta terapéutica en nuestro país. En este artículo analizamos la respuesta precoz favorable al tratamiento y sus perspectivas a futuro.
Abstract: Long-term home parenteral nutrition (HPN) is a life-saving treatment for patients with chronic intestinal failure, an invalidating condition. However, only 1 out of 3 countries can rely on this treatment and complications associated to chronic parenteral nutrition are rather frequent. The latter constitute the main indication for intestinal transplantion, a procedure that in most middle-income countries has not yet developed and has not shown the expected outcome. In recent years, intestinal rehabilitation has significantly improved at the global level with the use of GLP2, based on the growing evidence that proves the possibility of intestinal rehabilitation and independence from parenteral nutrition with Teduglutide, even in the case of patients with unfavorable anatomy. These results have caused a positive impact on survival and the quality of life of patients with chronic renal failure, and they can often abstain from transplant. The patient of the case study is the first one who received this therapy in our country and this article analyses his favorable early response to treatment and future perspectives.
Resumo: A insuficiência intestinal crônica (CIF) ou tipo III é uma condição incapacitante e a nutrição parenteral crônica (NPC) domiciliar é o tratamento que permite a sobrevida desses pacientes. No entanto, apenas 1 em cada 3 países latino-americanos dispõe desse recurso e as complicações da NPC não são raras. Essas complicações são as principais indicações para o transplante intestinal, procedimento que na maioria dos países de renda média não foi desenvolvido ou não apresentou os resultados esperados. Nos últimos anos, a reabilitação intestinal em todo o mundo tem melhorado substancialmente com o uso de sGLP2, com um número cada vez maior de evidências que mostram a possibilidade de reabilitação intestinal e independência da NPC, mesmo em pacientes com anatomia desfavorável. Esses resultados têm possibilitado prolongar a sobrevida e melhorar a qualidade de vida dos pacientes com CIF e, em muitos casos, dispensar o transplante. O paciente do caso que apresentamos é o primeiro a receber essa terapia em nosso país. Neste artigo, analisamos a resposta favorável ao tratamento precoce e suas perspectivas futuras.

ABSTRACT Systemic sclerosis (SSc) is a systemic autoimmune disease in which gastrointestinal manifestations are a frequent complication. Gastrointestinal involvement is present in up to 90 % of patients. The most affected areas are the esophagus and the anorectal tract. Reflux, heartburn and dysmotility are the leading causes of gastrointestinal discomfort. Disordered anorectal function can occur early in the course of SSc and is an important factor in the development of fecal incontinence. Current recommendations to treat gastrointestinal disorders in SSc include the use of proton pump inhibitors, prokinetics and rotating antibiotics. This review discusses the proposed pathophysiological mechanisms, the clinical presentation, the different diagnostic techniques and the current management of the involvement of each section of the gastrointestinal tract in SSc.
RESUMEN La esclerosis sistémica (ES) es una enfermedad autoinmune sistémica en la que las manifestaciones gastrointestinales son una complicación frecuente. El compromiso gastrointestinal está presente hasta en 90% de los pacientes. Las áreas más afectadas son el esófago y el tracto anorrectal. El reflujo, la pirosis y la dismotilidad son las principales causas de malestar gastrointestinal. La función anorrectal alterada puede presentarse temprano en el curso de la ES y es un factor importante en el desarrollo de incontinencia fecal. Las recomendaciones actuales para tratar los trastornos gastrointestinales en la ES incluyen el uso de inhibidores de la bomba de protones, procinéticos y de antibióticos en forma rotativa. Esta revisión discute los mecanismos fisiopatológicos propuestos, la presentación clínica, las diferentes técnicas de diagnóstico y el manejo actual del compromiso de cada sección del tracto gastrointestinal en la ES.

Chronic intestinal pseudo-obstruction (CIPO) is a rare and serious motility disorder in gastrointestinal tract, which mimics mechanical intestinal obstruction clinically. It may be primary (idiopathic CIPO) or secondary to a organic, systemic or metabolic disorder. The etiology and mechanism of idiopathic CIPO are not yet clear. It might be linked to neuromuscular disorders of the digestive tract. Although there are a variety of diagnostic approaches, no standard diagnostic criterion has been achieved. Improper and delayed treatment may cause the increase in mortality. In this review article, the current status in management of idiopathic CIPO was summarized.
ABSTRACT
Chronic intestinal pseudo-obstruction(CIPO)is a rare but serious intestinal dyskinesia characterized by impaired bowel motor function in the absence of mechanical intestinal obstruction. CIPO may be caused by primary and secondary factors that damage the enteric nervous system(neuropathy),smooth muscle(myopathy),and/or Cajal interstitial cells(interstitial disease). CIPO is extremely easy to missed diagnosis and misdiagnosis.The treatment of CIPO is very difficult.It is based on nutritional support,medicine and surgical treatment.At present,the occurrence,development and treatment of intestinal micro-ecology in CIPO has gradually attracted attention and may become a new treatment method for CIPO.
ABSTRACT
Chronic intestinal pseudo-obstruction(CIPO)is an intestinal motility dysfunction caused by intestinal myopathies or neuropathies or mesenchymopathies.The clinical manifestation is almost the same with mechanical intestinal obstruction,but in the absence of any obstruction in the gastrointestinal tract.According to etiology,it can be divided into primary and secondary.While according to gastrointestinal neuromuscular disorders,it can be categorized as myopathy,neuropathy and mesenchymopathy,which have different pathogenesis.The disease with the clinical manifestation,imaging examination or histopathology was diagnosed,but mechanical intestinal obstruction must be excluded.Presently,the therapies of CIPO mainly are stimulating the motility of intestine and ensuring the necessary nutrition of the children.The review is mainly focused on the research progress of the pathogenesis,clinical manifestation,diagnosis,therapy of pediatric CIPO in recent years.
ABSTRACT
Though intestinal tuberculosis is relatively a common ailment in India and other developing countries; enterolithiasis is a rarely encountered clinical and radiological entity found in this disease. Enteroliths are formed due to stasis caused by stricture formation in intestinal tuberculosis. We report a case of enterolithiasis secondary to intestinal tuberculosis.

Chronic intestinal pseudo-obstruction (CIP) is the most severe intestinal motility disorder. Small intestinal bacterial overgrowth (SIBO) is frequently associated to dysmotility. In spite of this association, there is scare data on the relation between CIP and SIBO. To establish occurrence of CIP in SIBO patients in inter-crisis periods. To compare clinical and manometric characteristics of SIBO and non-SIBO patients. Retrospective analysis of 40 CIP patients (average age: 41 years; range: 18-76 years; 75 percent women). The following elements were registered: symptoms (such as pain, distention, vomit, constipation, diarrhea and weight loss); findings of the intestinal manometry (neuropathic, miopatic and mix pattern; intestinal motility index); and SIBO using lactulose H2 breath test, defined as an increase > 20 ppm in 2 or more figures in the first 60 minutes. Statistical analysis: t-test y and comparison of two ratios. SIBO was observed in 60 percent of the patients with CIP. Three or more symptoms were observed in 70.8 percent of the patients with SIBO 50 percentwithout SIBO (p = NS). In patients with SIBO, the most frequent symptom was abdominal pain (70.8 percent p= 0.032). There were no differences between SIBO patients and the different motility patterns, however, the intestinal motility index was lower for the SIBO group (9.7 +/- 44 12.3 +/-7; p < 0.001). : There is a high prevalence of SIBO in CIP patients. This is associated to a major compromise of intestinal motility assessed by the intestinal motility index...
Introducción: La pseudoobstrucción intestinal crónica (POIC) es el trastorno más grave de la motilidad intestinal. El sobrecrecimiento bacteriano intestinal (SBI) se asocia frecuentemente a estados de dismotilidad. A pesar de esta asociación existen escasos datos sobre la relación entre POIC y SBI. Objetivo: Determinar SBI en pacientes con POIC en período inter-crisis. Comparar características clínicas y manométricas de pacientes con y sin SBI. Material y Método: Análisis retrospectivo de 40 pacientes con POIC (edad promedio: 41 años, rango: 18-76 años; 75 por ciento mujeres). Se registraron síntomas (dolor, distensión, vómitos, constipación, diarrea, baja de peso), hallazgos en manometría intestinal (patrón neuropático, miopático o mixto, índice de motilidad intestinal (IMI)) y SBI con test de H2 con lactulosa, definido como la elevación > 20 ppm en 2 o más cifras en los primeros 60 min. Análisis estadístico: t-test y comparación de 2 proporciones. Resultados: Se observó SBI en 60 por ciento de los pacientes con POIC. Tres o más síntomas se presentaron en 70,8 por ciento de los pacientes con SBI vs 50 por ciento en POIC sin SBI (p = NS). El síntoma dolor abdominal fue más frecuente en pacientes con SBI (70,8 por ciento vs 31,2 por ciento, p = 0,032). No hubo diferencias entre pacientes con SBI y los distintos patrones de motilidad, sin embargo, el IMI fue menor para el grupo con SBI (9,7 +/- 1,44 vs 12,3 +/- 1,7, p < 0,001). Conclusiones: Existe una alta prevalencia de SBI en pacientes con POIC. Esto se relaciona con mayor compromiso de la motilidad intestinal evaluado por el IMI.

Chronic intestinal pseudo-obstruction is a rare clinical syndrome which is characterized by intestinal obstruction without occluding lesions in the intestinal lumen and pregnancy is one of the important aggravating factors. Here, we report a case of a woman with intractable intestinal pseudo-obstruction that was precipitated by pregnancy. She could not make any stool passage for more than 4 weeks until a fetal gestational age of 17 weeks was reached. However, the patient could be maintained by repetitive colonoscopic decompressions and finally total colectomy could be performed successfully at a fetal gestational age of 21 weeks.

s:Primary chronic intestinal pseudo-obstruction (PCIPO)is a rare digestive syndrome characterized by derangement of gut propulsive motility which resembles mechanical obstruction, in the absence of any obstructive process. Treatment of intestinal pseudo-obstruction involves nutritional, pharmacological and surgical therapies, but it is often unsatisfactory and the long-term outcome is generally poor in the majority of cases. This article is aimed at reviewing the current knowledge on etiology, clinical features and management of patients affected by PCIPO.
ABSTRACT
Intestinal neuronal dysplasia (IND) type B is a disease of the submucosal plexus of intestine manifesting chronic intestinal obstruction or severe chronic constipation. IND is one of intestinal dysganglionoses and clinically closely associated with Hirschsprung's disease. Until recently, it is not fully clear whether IND is a congenital malformation or an acquired secondary condition related to some gastrointestinal problems. However, recently published data and consensus reports have enhanced our understanding of the pathogenesis and management of IND. The aim of this paper was to review the current state of knowledge regarding the controversial issues of IND including the etiology, classification, diagnostic criteria, and available therapeutic intervention.

La colitis ulcerosa es una inflamación crónica no granulomatosa, que afecta fundamentalmente al colon. Se caracteriza por inflamación y ulceraciones de la mucosa intestinal. La etiopatogenia es compleja y multifactorial. Los síntomas gastrointestinales dependen de la situación, magnitud y severidad de la inflamación. El diagnóstico se basa en la sospecha clínica apoyada por estudios de laboratorio y de gabinete y el tratamiento depende de la severidad del cuadro. Presentamos a un niño que curso con un cuadro de colitis ulcerosa fulminante y que evoluciono favorablemente con el tratamiento instaurado.
Ulcerative colitis is a chronic non granulomatous inflammation that affects mainly the colon. It is characterized by inflammation and ulceration of the intestinal mucosa. The etiology and pathogenesis is complex and due to several factors. Gastrointestinal symptoms depend on the location, size and severity of the inflammation. Diagnosis is based upon clinical examination supported by laboratory studies. Treatment depends on the severity of the case. We present the history of a child that showed a very severe case of ulcerative colitis who responded favorably to prescribed treatment.
ABSTRACT
Chronic intestinal pseudo-obstruction syndrome (CIPS) is a rare clinical condition in which impaired intestinal propulsion causes recurrent symptoms of bowel obstruction in the absence of mechanical obstruction. CIPS can be present as either primary or secondary although the latter is rare in children compared with adults. The primary abnormality consists of a degeneration of either the muscularis propria (visceral myopathy), or the myenteric plexus (visceral neuropathy). A 19 year old woman was recently admitted with recurrent abdominal distension and diarrhea. An abdominal plain X-ray revealed a marked dilated stomach and duodenum with some air-fluid levels. A small bowel series showed a diffusely dilated small bowel with multifocal angulation and spiculation. Computed tomograpy also revealed a dilated small bowel and distal ileal wall thickening. The patient was treated by duodenojejunostomy and ileal resection. Histologically the intestine showed thinning of the proper muscle layer with degeneration of smooth muscle cells replaced by fibrosis. Based on the specific histopathologic finding, in addition to the clinical history, physical finding and radiological evaluation, a diagnosis of sporadic visceral myopathy was rendered. The patient was treated through total parenteral nutrition with neostigmine, prokinetics, octreotide, and erythromycin postoperatively. However, she underwent ileostomy due to poor response from these therapies. After ileostomy, she improved without a recurrence of severe symptoms.

We report two cases of CIP with intractable abdominal distension. The first, an eight year old girl, suffered from severe symptoms and could not tolerate feeding. Ten mg cisapride was administered four times a day. The second child had less abdominal distension and received 10 mg cisapride three times a day. The symptoms and gastric emptying times were markedly improved in both cases. Thus cisapride is a promising medication in the treatment of CIP in children.
ABSTRACT
Amebic colitis is a disease revealing diverse clinical manifestations and endoscopic gross features and often confused with other types of colitis. In case of misdiagnosis as an idiopathic inflammatory bowel disease or delayed recognition of intestinal amebiasis, an undesirable outcome may occur resulting from erroneous administration of steroids or delayed antiamebic treatment. To demonstrate the pitfalls in the diagnosis and treatment of intestinal amebiasis, 3 cases of amebic colitis with atypical clinical manifestations are presented in this paper. In conclusion, despite the low sensitivities of routine stool examination for parasite and histopathologic confirmation in biopsy specimen, every effort must be made to find amebic trophozoites either in fresh stool or biopsy specimens for prompt and correct diagnosis of amebic colitis when we manage patients with chronic intestinal ulcerations, even though their clinical course and endoscopic findings are not typical of amebiasis. Moreover, following initial successful anti-amebic therapy, more careful clinical, endoscopical, and parasitological follow-up should be done for the early detection of recurrence.
