    Abstract Background: Appendiceal mucinous cystadenoma can present in various ways, and it is most commonly encountered incidentally during appendectomy, but mechanical intestinal obstruction secondary to an appendiceal mucocele has been rarely reported. Methods: We report a case of mechanical intestinal obstruction secondary to appendiceal mucinous cystadenoma. After nasogastric decompression and initial aggressive intravenous fluid resuscitation, an emergency operation was performed under the diagnosis of acute mechanical intestinal obstruction. Results: We performed an appendectomy and intraoperative enteral decompression without anastomoses. The pathologic examination (PE) revealed appendiceal mucinous cystadenoma. After the operation, the patient's recovery went smoothly, and the patient was discharged on the fifth postoperative day. No tumor recurrence was recorded over an 8 month follow-up period. Conclusion: Early operative intervention should be recommended to the patient with acute mechanical complete intestinal obstruction, especially the patient who had no previous abdominal surgery. And it is vital to discriminate benign and malignantappendiceal mucocel in determining the extent of surgery. PMID:28151903

    Chronic intestinal pseudo-obstruction (CIPO) is a severe digestive syndrome characterized by derangement of gut propulsive motility which resembles mechanical obstruction, in the absence of any obstructive process. Although uncommon in clinical practice, this syndrome represents one of the main causes of intestinal failure and is characterized by high morbidity and mortality. It may be idiopathic or secondary to a variety of diseases. Most cases are sporadic, even though familial forms with either dominant or recessive autosomal inheritance have been described. Based on histological features intestinal pseudo-obstruction can be classified into three main categories: neuropathies, mesenchymopathies, and myopathies, according on the predominant involvement of enteric neurones, interstitial cells of Cajal or smooth muscle cells, respectively. 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.

    Intestinal obstruction is one of the common surgical emergencies seen in daily practice. Postoperative adhesions are notorious for being the most common cause for intestinal obstruction. Occasionally, laparotomy findings do come as a surprise to surgeons. Here one such case is discussed. A patient was operated on with suspicion of intestinal obstruction secondary to postoperative adhesions. However, laparotomy revealed the appendix to be inflamed, curled around the terminal ileum and acting as a tourniquet. PMID:27437300

    Intestinal pseudo-obstruction is a condition characterised by clinical manifestations of mechanical obstruction of the intestine in the absence of any organic occlusion of the lumen. This syndrome has rarely been reported to complicate the course of systemic amyloidosis. We describe the case of a 64-year-old man who presented with the syndrome of small bowel pseudo-obstruction secondary to AL amyloid infiltration of the gastrointestinal tract. We comment on the pathophysiology and on the clinical importance of amyloidosis-associated intestinal pseudo-obstruction.

    Chronic intestinal pseudo-obstruction (CIPO) is a disease characterized by episodes resembling mechanical obstruction in the absence of organic, systemic, or metabolic disorders. Pseudo-obstruction is an uncommon condition and can result from primary (40%) or secondary (60%) causes. The most common symptoms are nausea, vomiting, abdominal distension, abdominal pain and constipation or diarrhea. These symptoms are usually present many years before CIPO diagnosis. They can lead to severe electrolyte disorders and malnutrition. Principles for management of patients with CIPO are: to establish a correct clinical diagnosis in excluding mechanical obstruction; to perform a symptomatic and physiologic assessment of the gastrointestinal tract involved; to look for extra-intestinal manifestations, especially for myopathy and neuropathy; to discuss in some cases a surgery for full-thickness intestinal biopsies, and/or a neuromuscular biopsy in case of mitochondrial cytopathy suspicion. The management is primarily focused on symptom control and nutritional support to prevent weight loss and malnutrition. Treatment of CIPO includes prokinetic agents which may help to reduce gastrointestinal symptoms Courses of antibiotics may be needed in patients with symptoms suggestive of bacterial overgrowth. When necessary, enteral nutrition is preferred. In carefully selected patients, feeding jejunostomy with or without decompression gastrostomy may be tried. Long term parenteral nutrition should be reserved for patients who can not tolerate enteral nutrition. Intestinal transplantation can be discussed in selected patients.

    Chronic intestinal pseudo-obstruction (CIP) is a rare and serious disorder of the gastrointestinal (GI) tract characterized as a motility disorder with the primary defect of impaired peristalsis; symptoms are consistent with a bowel obstruction, although mechanical obstruction cannot be identified. CIP is classified as a neuropathy, myopathy, or mesenchymopathy; it is a neuropathic process in the majority of patients. The natural history of CIP is generally that of a progressive disorder, although occasional patients with secondary CIP note significant symptomatic improvement when the underlying disorder is identified and treated. Symptoms vary from patient to patient depending on the location of the luminal GI tract involved and the degree of involvement; however, the small intestine is nearly always involved. Common symptoms include dysphagia, gastroesophageal reflux, abdominal pain, nausea, vomiting, bloating, abdominal distension, constipation or diarrhea, and involuntary weight loss. Unfortunately, these symptoms are nonspecific, which can contribute to misdiagnosis or a delay in diagnosis and treatment. Since many of the symptoms and signs suggest a mechanical bowel obstruction, diagnostic tests typically focus on uncovering a mechanical obstruction, although routine tests do not identify an obstructive process. Nutrition supplementation is required for many patients with CIP due to symptoms of dysphagia, nausea, vomiting, and weight loss. This review discusses the epidemiology, etiology, pathogenesis, diagnosis, and treatment of patients with CIP, with an emphasis on nutrition assessment and treatment options for patients with nutrition compromise.

    Chronic intestinal pseudo-obstruction (CIPO) is a syndrome characterized by the presence of recurrent episodes of clinical intestinal obstruction in the absence of obstructive lesions. Although this syndrome is rare, it causes a high morbidity. It is caused by a disturbance of the intestinal motility, that results in a failure of the progression of the intestinal content. Basically, the failure of the intestinal motility is a consequence of muscular disorder, neurological disorder or both. Usually, CIPO is secondary to other systemic disease; however, in the last years, many cases of primary CIPO have been described. The use of new manometric tecniques and specific histological procedures have allowed to clarify the pathogenesis of some of these entities including mitochondrial diseases and paraneoplasic syndromes. Clinical manifestations of CIPO are diverse, depending on the location and extension of the motility disorder. As the diagnosis of this disease is usually not an easy task, patients frecuently undergo unnecesary surgical interventions, are diagnosed of psyquiatric disorders, or the correct diagnosis is delayed several years after the first symptoms arise. The aims of the treatment are to maintain the nutritional condition and to improve symptoms using nutritional measures, drugs or, eventually, endoscopical or surgical procedures.

    The syndrome of intestinal pseudo-obstruction is a complex of signs and symptoms of intestinal obstruction without evidence of mechanical obstruction of the intestinal lumen. A patient with radiation-induced intestinal pseudoobstruction is described. The patient is a 74-year old woman with a history of chronic diarrhea, recurrent episodes of crampy abdominal pain, nausea and vomiting since receiving a 13,000 rad radiation dose to the pelvis in 1954. She has been hospitalized on many occasions for symptoms and signs of bowel obstruction. Upper gastrointestinal contrast roentgenograms with small bowel follow-through done during these episodes revealed multiple dilated loops of small bowel with no obstructing lesion. Barium enemas revealed no obstructing lesion. Each episode resolved with conservative therapy. Other secondary causes for intestinal pseudo-obstruction were ruled out in our patient. She gave no history of familial gastrointestinal disorders. Although postirradiation motility abnormalities have been demonstrated experimentally this is the first report of radiation induced intestinal pseudo-obstruction.

    Chronic intestinal pseudo-obstruction(CIPO) is a rare severe digestive disease in which clinical symptoms of intestinal obstruction appear without any mechanical cause. Pathophysiologically, CIPO shows ineffective intestinal propulsion due to an impairment of intestinal smooth muscle, enteric nervous system, and interstitial cells of Cajal(ICC). Sustained increased intra-bowel pressure often causes small intestinal malabsorption and bacterial translocation, and leads to malnutrition and blood stream infection (sepsis). Key points of the medical approach for CIPO are to improve nutritional status and reduce abdominal symptoms. Dietary cure and defecation control are the main options in mild cases, whereas home-parenteral-nutrition(HPN) and decompression therapy are often needed in severe cases. Stimulant laxatives, prokinetics and herbal medicine are usually used but often in fail. Percutaneous endoscopic gastrojejunostomy(PEG-J) tube may be burdenless compared to conventional ileus tube. Most important points in the management of this disease are to make a correct diagnosis as early as possible and avoid unnecessary surgery. However, no clear diagnostic criteria have been established so far. Manometry, scintigraphy, and full-thickness biopsy are the major examination for the CIPO diagnosis in the Western countries; however these specialized examinations are not popular in Japan. Therefore the Research Group(chief investigator, Atsushi Nakajima) proposed Japanese diagnostic criteria in 2009 to facilitate the diagnosis of this rare disease by the general physician. In 2013, we have reported that cine-MRI is a non-invasive diagnostic method for CIPO. Although further data are eagerly awaited, it can become a promising diagnostic tool in CIPO patients. Furthermore the Japanese criteria have been revised, and in 2014, the comprehensive criteria from a child to an adult have been devised. In 2015, CIPO is newly certified as Specified Rare and Intractable Disease which is

    Intestinal obstruction, revealed by obstruction syndrome, is defined by the cessation of the bowel function whatever the cause. Bowel obstructions are one of the most frequent reasons for hospitalisation in digestive system surgery. They represent a surgical emergency. Diagnosis must enable the obstruction to be confirmed and its mechanisms and location to be specified. The treatment must always include restoring water-electrolyte balance, particularly in elderly people.

    The term bezoar refers to an intraluminal mass in the gastrointestinal system caused by the accumulation of indigestible ingested materials, such as vegetables, fruits, and hair. Bezoars are responsible for 0.4%-4% of cases of mechanical intestinal obstruction. The clinical findings of bezoar-induced ileus do not differ from those of mechanical intestinal obstruction due to other causes. The appearance and localization of bezoars can be established with various imaging methods. Treatment of choice depends on the localization of the bezoar which makes the clinical findings.

    The most serious consequences of infection with the large roundworm, Ascaris lumbricoides, are complications requiring surgical intervention, particularly intestinal obstruction caused by a bolus of worms. A study was conducted to estimate the incidence of this complication among infected children in an area of the southeastern United States where ascariasis is endemic. A chart review at three rural Louisiana public hospitals revealed that 21 patients had been hospitalized with intestinal obstruction secondary to ascariasis over a 3-year period. The prevalence of ascariasis in three parishes (counties) served by these hospitals was calculated from the results of 2,360 stool examinations performed by the State Health Department and one hospital laboratory. The prevalence of ascariasis in 1- to 5-year-old children was similar to that in 6- to 12-year-olds and ranged from 8% to 28% in the three parishes. Prevalence rates were three times higher for blacks than for whites. It was found that most cases of intestinal obstruction occur in children in the 1- to 5-year age group and that this incidence approximates two such complications per 1,000 infected children per year.

    A preduodenal position of the portal vein is a rare anomaly reported in 52 cases in the literature. Two additional cases are reported here. In 54% of the cases of preduodenal portal vein (PPV) was combined with high intestinal obstruction and in one half of these cases PPV was considered obstructive. A critical review of these cases given the impression that obstructive PPV could well be a misinterpretation of the obstructive situation and the existence of obstructive PPV is doubted.

    Chronic intestinal pseudoobstruction (CIPO) is a rare entity characterized by recurrent clinical episodes of intestinal obstruction in which no mechanical cause is identified. There are multiple causes for this syndrome but two main groups can be distinguished: a) secondary to a systemic non-gastrointestinal disease; and b) primary or idiopathic originated from alterations in the components of the intestinal wall. The latter forms are the most uncommon and their diagnosis is generally difficult. In the present article, we describe nine patients with CIPO that were diagnosed in our center over the last six years. Four of them were diagnosed with primary or idiopathic form of CIPO and another four were clearly secondary to a systemic disease. The ninth case, which was initially diagnosed as secondary, is probably also a primary form of the disease. The number of patients diagnosed in our center, even thought small, makes us to hypothesize that the prevalence of CIPO is probably greater than is generally believed and that the reasons of its rarity are the incomplete understanding of its physiopathology and the difficulties to achieve a correct diagnosis.

    1997-05-01

    The treatment of intestinal obstruction (IO) in patients with advanced or terminal cancer represents an open and widely discussed topic in clinical oncology practice. As surgical palliation is a complex issue, the decision to advance with surgery should be made in consultation with the patients and family members. The prognostic factors, mainly the survival time and the surgical risks can be considered guideline indicators. If there is any possibility that surgery will be of benefit, the patient should be treated with intravenous fluids and nasogastric suction while appropriate radiological investigations are performed. When surgical intervention is contraindicated, symptomatic medical treatment should be started through continuous subcutaneous administration of analgesic and antiemetic drugs. Minor episodes of vomiting may occur, which do not trouble patients since the most distressing symptom, nausea, can be controlled. Dehydration may be avoided with a liquid diet in small quantities. In this way, it is possible to manage patients with IO for several weeks without the need of nasogastric suction or intravenous fluids. Percutaneous gastrostomy, nasogastric tube, or hypodermoclysis may be necessary for a small number of patients, principally with high obstruction, who have refractory symptoms.

    Chronic intestinal pseudo-obstruction represents a cause of persistent functional intestinal failure either "secondary" to specific conditions or "chronic intestinal idiopathic pseudo-obstruction" in origin. The diagnosis is mainly clinical, supported by radiological and/or endoscopic findings excluding any mechanical cause of intestinal obstruction. We reported a case of a 39-year-old woman with chronic intestinal idiopathic pseudo-obstruction, who underwent colectomy with ileorectal anastomosis; histological examination of the surgical specimen did not reveal myogenic or neurogenic defects or other pathological abnormalities indicative of an underlying neuromuscular impairment. Because of the apparent integrity of the gut neuromuscular layer, we tested whether a functional impairment affected colonic single smooth muscle cells. Muscle cells were isolated from the right colon and their contractile response to a receptor-dependent agonist evaluated in comparison to that obtained from controls. The cell contraction induced by acetylcholine in a dose response manner was markedly decreased in the patient affected by chronic intestinal idiopathic pseudo-obstruction compared with cells from controls (percentage of cell shortening with maximal dose of acetylcholine [10(-6)M]: 10.7+/-3% versus 34.2+/-4%, respectively). The present findings indicate a specific defect of colonic smooth muscle cells likely related to an ineffective response to acetylcholine.

    Baclofen is a gamma- aminobutyric acid B (GABA B) agonist used for the management of spasticity associated with spinal cord injury. Oral baclofen might cause constipation, but intestinal pseudo-obstruction is very rare. We report a 50-year-old male with spasticity following cervical discectomy (C3-4) on oral baclofen for 6 months with intestinal pseudo-obstruction. He had undergone open suprapubic cystostomy for traumatic urethral injury, 45 days prior to the presentation and adhesive intestinal obstruction was also considered a possibility. However, there were no air fluid levels on abdominal radiographs and ultrasound abdomen was non-contributory. Withdrawal of baclofen was therapeutic in this patient. This case is being reported to highlight the rare possibility of oral baclofen induced intestinal pseudo-obstruction.

    Chronic intestinal pseudo-obstruction is an uncommon syndrome characterized by relapsing episodes suggesting intestinal obstruction during which no mechanical causes are identified to account for symptoms. Etiologic factors may be manifold. Among them a number of neurologic conditions, gastrointestinal smooth muscle myopathies, endocrino-metabolic and autoimmune diseases, and the use of selected drugs stand out. We report a case of chronic intestinal pseudo-obstruction originating in a sporadic, primary intestinal myopathy that corresponds to no type thus far described. A histological study of the intestinal wall showed disrupted muscle bundles and the presence of interstitial edema. Myocytes had severe degenerative changes, and no alterations were seen in submucosal and myenteric plexus neurons. The activity of enzyme complexes in the mitochondrial respiratory chain, and of thymidine phosphorylase was normal. No mitochondrial DNA changes were seen.

    Strongyloides stercolaris infestation is rather rare in Iraq. Individuals with infection confined to the intestinal tract are often asymptomatic. Symptoms include abdominal pain, diarrhea, weight loss and other non-specific complaints. The diagnosis depends upon repeated examination of stool and duodenal aspirate. Two cases presenting as sub-acute intestinal obstruction and mimicking primary intestinal lymphoma (PIL) on presentation are presented. Differentiation between the two conditions regarding presenting features, barium studies and pathology are discussed.

  13. Encountering Meckel's diverticulum in emergency surgery for ascaridial intestinal obstruction

    PubMed Central

    2010-01-01

    Background Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract. In children with intestinal ascariasis, the diverticulum remains asymptomatic or rarely the Ascaris lumbricoides may lead to its complications in the presence of massive intestinal roundworm load. Given that preoperative diagnosis is seldom carried out, when Meckel's diverticulum is found at laparotomy for obstructive intestinal complications of roundworm, the diverticulum should be removed as complications may occur at any time. The aim of this study was to describe the findings of concomitant presence of Meckel's diverticulum who had surgical intervention in symptomatic intestinal ascariasis in children. Methods A retrospective case review study of 14 children who had surgical intervention for symptomatic intestinal ascariasis having the presence of concomitant Meckel's diverticulum was done. The study was done at SMHS Hospital Srinagar, Kashmir. Results A total of the 14 children who had ascaridial intestinal obstruction with concomitant presence of Meckel's diverticulum were studied. Age of children ranged from 4-12 years, male:female ratio was 1.8:1. Nine patients had asymptomatic Meckel's diverticulum, whereas 5 patients with symptomatic signs were found in the course of emergency surgery for ascaridial intestinal obstruction. Conclusion Meckel's diverticulum in intestinal ascariasis may pursue silent course or may be accompanied with complications of the diverticulitis, perforation or the gangrene. Incidental finding of the Meckel's diverticulum in the intestinal ascariasis should have removal. PMID:20529382

    Chronic intestinal pseudo-obstruction (CIPO) is a rare clinical syndrome of ineffective intestinal motility characterised by clinical and radiological evidence of intestinal obstruction with no identifiable mechanical lesion. CIPO can either be idiopathic or secondary to a systemic disease, like systemic lupus erythematosus (SLE). Fewer than 30 cases of CIPO secondary to SLE have been reported so far. Here we describe a case of SLE with the initial presentation of CIPO. In SLE-related CIPO, treatment includes a combination of high-dose intravenous corticosteroids, immunosuppressants and supportive care. With awareness of this condition, unnecessary surgical intervention and repeated invasive procedures could be avoided. Early initiation of treatment would avoid complications and bring about resolution of symptoms.

    Context: Bowel obstruction is one of the most common causes of acute abdomen. Because of heterogeneity of patients’ population and variety of causes, therapeutic strategies are not standardized, so treatment of intestinal obstruction is a surgical challenge in many cases. A traditional medicine approach could help detect some issues that were ignored by modern medicine. One of the major schools of medicine, with a history of several thousand years, is Iranian traditional medicine. In this regard, Avicenna, who lived in the medieval period, has had a great influence on the medical knowledge of the world by writing an encyclopedia of medicine entitled “Qanun of Medicine.” Evidence Acquisition: The aim of this study was to investigate Avicenna’s views on the causes of intestinal obstruction and comparing them to modern medicine views. This is a review study on an Iranian traditional textbook of medicine by Avicenna, entitled “Qanun of Medicine” (in short “Qanun”). We used Qanun in its original language (Arabic) along with its Persian translation. It consists of 5 books. Part 16 of the third book talks about intestinal anatomy and introduces some intestinal diseases such as “qoolinj” and “ilavos.” Intestinal obstruction can be a kind of “qoolinj” or “ilavos” disease. All intestinal obstruction etiologies in Qanun are searched in international and Iranian databases (Scopus, ISI, SID, and Iranmedex) and similar causes in modern medicine will be discussed in this article. Results: According to Qanun, 16 causes are involved in intestinal etiologies of bowel obstruction such as “reeh,” mucoid phlegm, abdominal hot and dry distemperament, decreased bile secretion, job, and so on while modern medicine considers some of them, for instance, volvulus, intestinal herniation, worm, intestinal pseudo-obstruction, and opiate. Conclusions: Attention to the similar causes of intestinal obstruction in modern medicine and traditional medicine is the

    Background/Aims Chronic intestinal pseudo-obstruction (CIPO) is a rare syndrome characterized by a failure of the propulsion of intraluminal contents and recurrent symptoms of partial bowel obstruction in the absence of mechanical obstruction. Regional variations of the intestinal compromise have been described. Intestinal manometry can indicate the pathophysiology and prognosis. Our objective is to establish the demographic and clinical characteristics of group Chilean patients and analyze the motility of the small intestine and its prognostic value. Methods Patients with symptoms of intestinal pseudo-obstruction with dilated bowel loops were included, in all of whom a manometry of the small intestine was performed using perfused catheters. Results Of the 64 patients included, 51 women (average age 41.5 ± 17.6 years), 54 primary and 10 secondary CIPO were included. Dilatation of the small intestine was the only finding in 38 patients; in the remaining, the compromise was associated with other segments, primarily the colon. Forty-nine patients underwent 65 surgeries, mainly exploratory laparotomies and colectomies. Intestinal manometry was performed on all patients; 4 “patterns” were observed: neuropathic (n = 26), myopathic (n = 3), mixed (n = 24), and a group without motor activity (n = 11). The most relevant findings were the complex migrating motor disorders and decreased frequency and propagation of contractions. The 9 patients who died had a severe myopathic compromise. Conclusions In our series, isolated small bowel compromise was the most common disorder. Neuropathic motor compromise was observed in most of the patients. Mortality was associated with severe myopathic compromise. PMID:27669829

    Intestinal obstruction belongs to highly severe conditions in gastroenterology, namely from the viewpoint of quick and correct diagnosis as well as at determining rational and effective therapy. Etiological multifactorial characteristics leading to processes resulting in mechanical or dynamic obstruction of the intestine, often referred to as paralytic ileus, are undoubtedly serious factors influencing the accuracy of diagnosis and therapeutic approach. Digestive endoscopy is a mandatory method in the diagnosis of intestinal obstructions. Diagnostic endoscopy, colonoscopy in the involvement of the large intestine or enteroscopy in the case of incomplete obstruction of the small intestine are the methods indicated in the majority of obstructive intestinal lesions. Besides their diagnostic importance, they also enable an effective therapeutic approach which may immediately follow the diagnostic intervention. Besides endoscopy that--due to the nature of performance--belongs to invasive methods, the diagnosis of obstructive intestinal processes is unthinkable without the use of non-invasive imaging methods. Abdominal ultrasound examination, a widely applied method, provides--under optimal examination conditions--information, e.g., about the width of the intestinal lumen or about the intestinal wall thickness; however, the specificity of investigation is not always sufficient. Both specificity and sensitivity of exploration are increased by a plain X-ray of the abdomen supplementing the ultrasound examination. Better results are achieved when the abdominal cavity is inspected by means of spiral CT examination that is nowadays not fashionable but highly effectively applied in the modification of the so-called CT enteroclysis or CT colonography. The usage of magnetic resonance (e.g. virtual colonography) is similar, but its efficacy is lower than that of CT examination. From a gastroenterologist's perspective, endoscopic examination is the fundamental diagnostic and

    Intestinal pseudo-obstruction (IPO) is a rare but dangerous complication of systemic lupus erythematosus (SLE) when the patient has no other manifestations except gastrointestinal symptoms. We performed 1 patient with a 2-month history of recurrent vomiting and abdominal distension. She admitted past surgical histories of cesarean section and appendectomy. A physical examination revealed tenderness in the right lower abdominal on palpation and bowel sounds were weak, 2 to 3 bpm. An x-ray and CT of her abdomen showed intestinal obstruction. The initial diagnosis was adhesive intestinal obstruction. She received surgical treatment because her symptoms had gradually become more frequent and persistent. But she vomited again 2 weeks later after the surgery. Further immunology tests indicated that she had an IPO secondary to SLE. We treated the patient with methylprednisolone pulse for 3 days and followed by prednisone orally. The patient had a good response. Complete remission was achieved on 8 years follow-up. The importance of IPO secondary to SLE lies in an early diagnosis. After the diagnosis is established, immunosuppressive therapy should be the initial and first-line treatment, and surgical intervention is often disappointing and should be carefully avoided. It is necessary to enhance awareness of doctors to IPO secondary to SLE.

    Anisakiasis, a parasitic infection by larvae of the nematode Anisakis found in raw or undercooked saltwater fish, mostly involves stomach but rarely small intestine. We report a rare case of a 61-year-old man who presented with abdominal pain and developed small bowel obstruction caused by intestinal anisakiasis. Abdominal computed tomography revealed segmental edema of the intestinal wall with proximal dilatation. The patient underwent urgent laparotomy because strangulated small bowel obstruction was suspected. A localized portion of the intestine around jejunoileal junction was found to be erythematous, edematous, and hardened, which was resected. The resected specimen showed a linear whitish worm, Anisakis simplex, penetrating into the intestinal mucosa. It is often clinically challenging to consider intestinal anisakiasis in the differential diagnosis because of its nonspecific abdominal symptoms and findings. Although gastrointestinal anisakiasis is still rare in the United States, the incidence is expected to rise given the growing popularity of Japanese cuisine such as sushi or sashimi. Anisakiasis should be considered as one of the differential diagnoses in patients with nonspecific abdominal symptoms after consumption of raw or undercooked fish.

    Lymphocytic intestinal leiomyositis is a rare entity, which causes chronic intestinal pseudo-obstruction (CIPO) in children. We present the first case of a boy who had pure red cell anemia 1 year before onset. Prolonged ileus developed after gastroenteritis and the patient was diagnosed using a biopsy of the intestinal wall. Findings from the present case indicate that there are three important factors for accurate diagnosis: history of enteritis, positive serum smooth muscle antibody, and lymphocyte infiltration with muscle destruction in the muscularis propria in the intestinal wall. Earlier diagnosis and induction of immunosuppressive therapy may be essential for a better outcome.

    Chronic idiopathic intestinal pseudo-obstruction is a rare and serious chronic disease starting in childhood, which can affect the entire digestive tract. It is caused by a peristalsis intestinal disorder that leads to occlusions without any obvious obstruction. Few studies have been carried out regarding the prognosis of this illness. This disease is often diagnosed by a process of elimination, but some histological anomalies have been present in the digestive wall of certain patients. This clinical case concerns a 17-year-old girl affected by CIPO and eating disorders. It seems difficult to discriminate between digestive disorders and eating disorders. What psychological effects can this severe pathology have? Are eating disorders induced by CIPO? These questions are raised in this article through the example of this patient's somatopsychic complexity and the ensuing difficulties in her overall care.

    Chronic intestinal pseudo-obstruction (CIP) is an uncommon disorder that may be of primary or secondary origin. We report a case of a 37-year-old woman with CIP due to inflammatory disorder of unknown origin involving the skin (eosinophilic fasciitis), the lungs (decreased diffusion capacity) and the gastrointestinal tract. History, clinical examination, plain abdominal film, barium X-ray and colonoscopy established a diagnosis of recurrent pseudo-obstruction. A full-thickness biopsy was performed during explorative laparotomy, and histological examination revealed findings compatible with an inflammatory myopathy due to a dense lymphoid infiltrate and extensive loss of the muscularis propria layers. Immunosuppressive therapy with cyclosporin was initiated, with significant clinical improvement. This case illustrates another form of CIP, characterized by an inflammatory myopathy, which is histologically distinct from other known visceral myopathies and neuropathies.

    Intestinal pseudo-obstruction is more commonly known in its chronic form (CIPO), a cluster of rare diseases characterized by gastrointestinal muscle and nerve impairment, so severe to result in a markedly compromised peristalsis mimicking an intestinal occlusion. The management of CIPO requires the cooperation of a group of specialists: the disease has to be confirmed by a number of tests to avoid mistakes in the differential diagnosis. The treatment should be aimed at relieving symptoms arising from gut dysmotility (ideally using prokinetic agents), controlling abdominal pain (possibly with non-opioid antinociceptive drugs) and optimizing nutritional support. Furthermore, a thorough diagnostic work-up is mandatory to avoid unnecessary (potentially harmful) surgery and to select patients with clear indication to intestinal or multivisceral transplantation.

    Chronic intestinal pseudo-obstruction (CIPO), one of the most severe gastrointestinal motility disorders, is a condition characterized by a clinical picture mimicking small bowel occlusion with related symptoms and signs in the absence of demonstrable mechanical obstruction. Analysis of full-thickness biopsy samples may unravel structural changes of the neuromuscular layer involving the whole gut, although the midgut is usually worst affected. Intestinal pseudo-obstruction can occur in association with systemic neurological, endocrine, and connective tissue diseases or malignancy but, when no recognizable etiology is found, CIPO is referred to as idiopathic (CIIPO). The latter form can be diagnosed early in life due to a genetic etiology or in adulthood when a viral origin may be considered. This review addresses the hypothesis that some systemic neurotrophic viral infections can affect the enteric nervous system thereby altering normal peristaltic activity. Available data are reviewed, focusing specifically on herpesviruses or polyomaviruses (JC virus). These suggest that in comparison to a proportion of CIIPO patients, healthy controls rarely harbor viral DNA in the myenteric plexus, leaving open the possibility that a viral infection might have an etiologic role in the development of CIIPO. The review thus provides some new perspectives in the pathophysiology and perhaps targeted treatment of CIIPO.

    Intestinal pseudo-obstruction (IPO) is an uncommon and severe complication of systemic lupus erythematosus (SLE). We report a 24-year-old female with a 2 year SLE duration who presented with abdominal pain, vomiting, constipation and abdominal distention. Plain abdominal radiograph showed multiple air-fluid levels of the small bowel. Computed tomographic scan of the abdomen revealed dilated small bowel loops without mechanical obstruction. Urinary tract involvement was also demonstrated. IPO was diagnosed and the patient responded well to immunosuppressive treatment. IPO is a recently recognized manifestation of SLE that may be the presenting manifestation of the systemic disease or occur more commonly during disease course. Early recognition of IPO is necessary to institute appropriate medical treatment and to avoid inappropriate surgical intervention.

Intestinal obstruction was confirmed with upright abdominal radiography and computerized tomography scan which showed dilation of the small intestines and a thermometer in the abdominal cavity. Then laparotomy was performed. A scar was observed at the fundus of the bladder and a thermometer was adhering to the small bowels and mesentery which resulted in intestinal obstruction. Abdominal cramps were eliminated and defecation and flatus recovered soon after removal of the thermometer. PMID:24605042

    Chronic intestinal pseudo-obstruction (CIPO) is a rare disease due to a severe gastrointestinal motility disorder which may mimic, on both clinical and radiological grounds, mechanical obstruction. We report a case of a 26-year-old woman who presented to our institution for plain abdominal radiography for referred long-lasting constipation with recurrent episodes of abdominal pain and distension. At X-ray, performed both in the upright and supine position, an isolated air-fluid level was depicted in the left flank, together with a number of radiological signs suggestive of pneumoperitoneum. First, subphrenic radiolucency could be observed in the upright film. Second, the intestinal wall of some jejunal loops appeared to be outlined in the right flank. Third, the inferior cardiac border was clearly depicted in the upright film. The patient however had no evidence of peritoneal signs but only hypoactive bowel movements. Unenhanced multi-detector computed tomography (MDCT) of the abdomen and pelvis was therefore performed. MDCT revealed abnormal air-driven distension of the small and large bowel, without evidence of extra-luminal air. All radiological signs of pneumoperitoneum turned out to be false-positive results. The patient was submitted to pan-colonoscopy and to anorectal manometry to rule out Hirshprung's disease, and was finally discharged with a diagnosis of CIPO.

    Intestinal obstruction is associated with significant morbidity and mortality. Scientific assessment of the cause, site of obstruction, appropriate correction of the fluid deficit and electrolyte imbalance with preoperative stabilization of blood gases is ideal as a preoperative workup. Placement of a preoperative epidural catheter especially in the thoracic interspace takes care of perioperative pain and stress reduction. Intraoperative management by controlled general anesthesia administering a relative high inspired fraction of oxygen with invasive monitoring in selected sick cases is mandatory. Preoperative monitoring and stabilizing raised intra-abdominal pressure reduces morbidity. Caution should be exercised during opening and closure of abdomen to avoid cardiorespiratory ill effects. There should be an emphasis on avoiding hypothermia. The use of nonsteroidal anti-inflammatory drugs may worsen sick, fragile patients. The use of sugammadex rather than neostigmine will obscure certain controversies in the healing of intestinal anastomotic site. Replacement of blood loss continued correction of fluids and electrolytes with possible postoperative mechanical ventilation in sick cases may improve outcomes in these patients. PMID:27746522

In the second group, the study was carried out after modeling 12-hours acute adhesive intestinal obstruction. To the third group at the beginning was given a single injection of four component mixture (carboxyperitoneum gel carboxymetiltcellulose novocaine and antibiotic) into the abdominal cavity. In the first group under the condition of tension carboxyperitoneum after a day of use there were signs of desiccations of visceral peritoneum. The increase of lipid peroxidation products and decrease of antioxidant enzymes were also observed. In the second group of animals these processes were exacerbated by acute adhesive intestinal obstruction. In the third group intraabdominal use of four component disperse mixture reduced the negative organic and functional changes in visceral peritoneum and improved its protective properties.

    Chronic intestinal pseudo-obstruction is a severe, often unrecognized disease characterized by disabling and potentially life-threatening complications over time. The diagnosis is based on the evidence of typical clinical manifestations, radiological evidence of distended bowel loops with air-fluid levels, and the exclusion of any organic obstruction of the gut lumen. The radiological sign of intestinal occlusion allows the distinction from enteric dysmotility, which is characterized by better outcomes. Manometry can play a supportive role in defining the diagnosis, and differences in the manometric pattern of chronic intestinal pseudo-obstruction and enteric dysmotility have been shown. The disease is often unrecognized, and the diagnosis, therefore, delayed by several years. Thus, the majority of patients undergo useless and potentially dangerous surgeries. Long-term outcomes are generally poor despite surgical and medical therapies characterized by disabling and potentially life-threatening complications over time. A substantial percentage of patients requires parenteral nutrition. Failure of this nutritional support represents an indication for small bowel transplantation.

    The effects of elevated intraluminal hydrostatic pressure on the active absorption of the amino acid selenium 75 L-methionine has been analyzed in the normal and obstructed small intestine. An intestinal loop of defined position and length was included in a recircling perfusion system from which the elimination rate of the radiolabeled amino acid was measured. Preset pressure levels within the system were maintained by a servo-controlled unit, which added or subtracted volume to keep the pressure constant. The rate of amino acid elimination increased when the nonobstructed loop was subjected to a pressure of 10 cm H2O but decreased when exposed to 20cm H2O. Using a loop of intestine subjected to 48 hours of obstruction, amino acid elimination was greatly retarded compared with that of the nonobstructed loop. By increasing the intraluminal pressure to 10 and 20 cm H2O, the elimination rate increased, equalling that of the nonobstructed gut. The results suggest that intestinal obstruction per se decreases active absorption secondary to impaired intestinal viability. Moderately increased intraluminal pressure adds a driving force to L-methionine absorption, the mechanism of which is obscure.

    Paraneoplastic syndromes can precede the initial manifestation and diagnosis of cancer. Paraneoplastic syndromes are a heterogeneous group of disorders caused by mechanisms other than the local presence of tumor cells. These phenomena are mediated by humoral factors secreted by tumor cells or by tumor mediated immune responses. Among paraneoplastic syndromes, chronic intestinal pseudo-obstruction (CIPO) is rare and represents a particularly difficult clinical challenge. Paraneoplastic CIPO is a highly morbid syndrome characterized by impaired gastrointestinal propulsion with symptoms and signs of mechanical bowel obstruction. Clinical outcomes of paraneoplastic CIPO are often deleterious. The current standard of care for the management of CIPO includes supportive treatment with promotility and anti-secretory agents. However, the majority of patients with CIPO eventually require the resection of the non-functioning gut segment. Here, we present a 62-year-old patient with anti-Hu antibody associated paraneoplastic CIPO and underlying small cell lung cancer who underwent treatment with cisplatin and etoposide. Herein, we discuss diagnosis, prognosis, proposed mechanisms, treatment options, and future potential therapeutic strategies of paraneoplastic CIPO.

    Introduction Mechanical intestinal obstruction is a disorder associated with intra-abdominal hypertension and abdominal compartment syndrome. As the large intestine intraluminal and intra-abdominal pressures are increased, so the patient’s risk for intestinal ischaemia. Previous studies have focused on hypoperfusion and bacterial translocation without considering the concomitant effect of intra-abdominal hypertension. The objective of this study was to design and evaluate a mechanical intestinal obstruction model in pigs similar to the human pathophysiology. Materials and Methods Fifteen pigs were divided into three groups: a control group (n = 5) and two groups of 5 pigs with intra-abdominal hypertension induced by mechanical intestinal obstruction. The intra-abdominal pressures of 20 mmHg were maintained for 2 and 5 hours respectively. Hemodynamic, respiratory and gastric intramucosal pH values, as well as blood tests were recorded every 30 min. Results Significant differences between the control and mechanical intestinal obstruction groups were noted. The mean arterial pressure, cardiac index, dynamic pulmonary compliance and abdominal perfusion pressure decreased. The systemic vascular resistance index, central venous pressure, pulse pressure variation, airway resistance and lactate increased within 2 hours from starting intra-abdominal hypertension (p<0.05). In addition, we observed increased values for the peak and plateau airway pressures, and low values of gastric intramucosal pH in the mechanical intestinal obstruction groups that were significant after 3 hours. Conclusion The mechanical intestinal obstruction model appears to adequately simulate the pathophysiology of intestinal obstruction that occurs in humans. Monitoring abdominal perfusion pressure, dynamic pulmonary compliance, gastric intramucosal pH and lactate values may provide insight in predicting the effects on endorgan function in patients with mechanical intestinal obstruction.

    Intestinal pseudo-obstruction is considered to be one of the most frequent gastrointestinal manifestations of myasthenia gravis, accompanied by the presence of neoplasia of the thymus gland in the vast majority of the cases presented in the international literature. Despite the fact that myasthenia gravis has been implicated to be the cause of recurrent episodes of intestinal pseudo-obstruction, adhesive ileus has never been reported to complicate this - in any sense rare - condition. We present a unique case of a patient with myasthenia gravis, free of thymus neoplasia, who was submitted to emergency surgery due to the presence of extended adhesive ileus as a complication of chronic intestinal functional obstruction.

    Superior mesenteric artery (SMA) syndrome is an uncommon cause of intestinal obstruction and seldom been mentioned in palliative care. Hereby, we reported a case of SMA syndrome who presented with symptoms of upper intestinal obstruction in a 68-year-old patient; subsequent CT findings were classical of SMA syndrome. The patient's history of poliomyelitis and recent significant weight loss were the predisposing factors for SMA syndrome. It also highlights the importance of monitoring signs and symptoms of intestinal obstruction in such patients before considering switching to oral feeding.

    Intestinal obstruction in pregnancy is rare and is mainly caused by prior pelvic surgery. We herein report a case of intestinal obstruction in a pregnant female with a history of laparoscopic myomectomy, who presented with hypogastric pain, abdominal distension, and vomiting at 26 weeks of gestation. A simple intestinal obstruction was diagnosed by MRI. Conservative treatments, including intravenous hyperalimentation and the placement of an ileus tube, were provided and her abdominal symptoms improved for 14 days. After restarting oral intake, she had no abdominal symptoms. She gave birth to a 2,146 g female infant by caesarean section at 37 weeks and 1 day of gestation. Although an area of cicatrization, which was thought to have been the starting point of the occlusion that caused the intestinal obstruction, was found, the excision of the small intestine was not necessary. Her postoperative course was uneventful. Intestinal obstruction requires a prompt diagnosis and aggressive intervention may be necessary to minimize the morbidity and mortality associated with this rare complication of pregnancy. MRI can be safely used during pregnancy to diagnose intestinal obstruction and intravenous hyperalimentation may improve the maternal and fetal prognoses. PMID:27999695

    Chronic intestinal pseudo-obstruction (CIPO) is a heterogeneous group of rare disorders characterised by symptoms of intestinal obstruction with no mechanical evidence of obstruction. It is caused by ineffective intestinal contractions due to visceral neuropathy and/or neuropathy. In adults, CIPO is mostly secondary. The most common causes are metabolic disorders, connective tissue disorders, neuropathic drug related injuries, paraneoplasic and post-infectious syndromes and amyloidosis. Secondary forms of CIPO have been reported with anti-Hu antibodies. This corresponds to an antineuronal antibody that recognizes a protein expressed in the nuclei of neuron (ANNA-1) and neoplasic cells. The anti-Hu antibody must be searched for in patients over 40 years old with CIPO (associated with small cell lung cancer in 75% of cases). Recently, the association of CIPO and the anti-Hu antibody has been described without associated neoplasia. We report a case of an association of CIPO and anti-Hu antibody without cancer after 13 years of follow-up.

    Uretero-inguinal hernia in patients with native kidneys is rare. We report a case of an 84-year-old man who was diagnosed with obstructive uropathy secondary to uretero-inguinal hernia, with no past history of herniorrhaphy or congenital genitourinary malformation. Uretero-inguinal hernias are predominantly indirect inguinal hernias and may be paraperitoneal or extraperitoneal. Computed tomography (CT) is a non-invasive diagnostic tool for uretero-inguinal hernia. Herniorrhaphy is indicated in all cases of uretero-inguinal hernia to prevent obstructive uropathy.

    We report a 72 years old woman with mild arterial hypertension and no other pathological history who presented an acute pulmonary edema due to acute obstruction of the upper airway secondary to vocal chord paralysis developing during the immediate postoperative phase of thyroidectomy. The acute pulmonary edema resolved after application of tracheal reintubation, mechanical ventilation controlled with end expiratory positive pressure, diuretics, morphine, and liquid restriction. We discuss the possible etiopathogenic possibilities of this infrequent clinical picture and we suggest that all patients who suffered and acute obstruction of the upper airways require a careful clinical surveillance in order to prevent the development of the pulmonary syndrome.

    A 32 year old woman presented with acute onset of abdominal pain and fever. An urgent computerised tomography (CT) of the whole abdomen showed dilated loop at the terminal ileum in the right lower abdomen with thickening of the wall and oedema. The CT was suggestive of distal small bowel obstruction at the ileum with surrounding wall oedema. Multiple biopsies taken from the terminal ileum and colon on colonoscopy were all unremarkable. She represented one-year later with a recurrence of intestinal obstruction. CT enteroclysis showed collapse at the distal 3 cm segment of the terminal ileum. There was no associated wall thickening, active inflammatory changes or ileitis. This was suspicious of post-inflammatory change or fibrosis. She was subsequently found to have selective IgA deficiency with recurrent infection in the terminal ileum resulting in intestinal obstruction. In conclusion, selective IgA deficiency should be considered in patients with recurrent intestinal obstruction without anatomical obstructions. PMID:28090187

    Intestinal pseudo-obstruction is a rare and relatively unknown complication of phaeochromocytoma÷ paraganglioma (PCC÷PGL). Its pathophysiology can be explained by the hypersecretion of catecholamines, which may reduce the peristaltic activity of the gastrointestinal tract. Clinically, this can result in chronic constipation, intestinal pseudo-obstruction or even intestinal perforation. We conducted a comprehensive literature search and retrieved 34 cases of pseudo-obstruction caused by either benign or malignant PCC÷PGL. We also included a case from our centre that has not been described earlier. We conclude that intestinal pseudo-obstruction is a rare but potentially life-threatening complication of PCC÷PGL. Intravenous administration of phentolamine is the most frequently described treatment when surgical resection of the PCC÷PGL is not feasible.

    Ovarian remnant syndrome (ORS) is a rare condition, in which the ovarian tissue is inadvertently left behind after difficult oophorectomy. The most common preexisting conditions associated for this complication include endometriosis, pelvic inflammatory disease, and prior abdominal surgery as in these conditions, removal of ovarian tissue becomes difficult. This is likely due to the presence of the dense fibrotic adhesions between an ovary and the surrounding structures. This residual ovarian tissue can become functional and cystic. A 56-year-old multigravida postmenopausal female was diagnosed with intestinal obstruction. She had multiple abdominal surgeries in the past, including cholecystectomy, appendectomy, hysterectomy, and bilateral salpingo-oophorectomy. Patient underwent exploratory laparotomy. Intraoperatively, extensive adhesions and scarring of bowel wall were present and approximately 15 cm proximal to the terminal ileum, a small bowel mesenteric nodule was present. Histopathology of the mesenteric nodule was consistent with the diagnosis of overian remnant. ORS can be prevented with careful resection of the entire ovarian tissue during the difficulty oophorectomy so that no ovarian tissue is left behind. PMID:28096643

    Paraneoplastic neurologic syndromes (PNS) are uncommon, affecting fewer than 1 in 10,000 patients with cancer. PNS, while rare, can cause significant morbidity and impose enormous socio-economic costs, besides severely affecting quality of life. PNS can involve any part of the nervous system and can present as limbic encephalitis, subacute cerebellar ataxias, opsoclonus-myoclonus, retinopathies, chronic intestinal pseudo-obstruction (CIPO), sensory neuronopathy, Lambert-Eaton myasthenic syndrome, stiff-person syndrome, and encephalomyelitis. The standard of care for CIPO includes the use of promotility and anti-secretory agents and the resection of the non-functioning gut segment; all of which can cause significant compromise in the quality of life. There is significant evidence that paraneoplastic neurologic syndromes are associated with antibodies directed against certain nerve antigens. We successfully treated a patient with CIPO in the setting of small cell lung cancer with a combination of rituximab and cyclophosphamide. The patient, who had failed to respond to prokinetic agents, anti-secretory therapy, and multiple resections, responded to the immunomodulatory therapy, with minimal residuals with PEG tube feeding and sustained ostomy output. The use of rituximab and cyclophosphamide should therefore be considered in patients with CIPO, especially if it can avoid complicated surgical procedures.

    CIPO is the very “tip of the iceberg” of functional gastrointestinal disorders, being a rare and frequently misdiagnosed condition characterized by an overall poor outcome. Diagnosis should be based on clinical features, natural history and radiologic findings. There is no cure for CIPO and management strategies include a wide array of nutritional, pharmacologic, and surgical options which are directed to minimize malnutrition, promote gut motility and reduce complications of stasis (ie, bacterial overgrowth). Pain may become so severe to necessitate major analgesic drugs. Underlying causes of secondary CIPO should be thoroughly investigated and, if detected, treated accordingly. Surgery should be indicated only in a highly selected, well characterized subset of patients, while isolated intestinal or multivisceral transplantation is a rescue therapy only in those patients with intestinal failure unsuitable for or unable to continue with TPN/HPN. Future perspectives in CIPO will be directed toward an accurate genomic/proteomic phenotying of these rare, challenging patients. Unveiling causative mechanisms of neuro-ICC-muscular abnormalities will pave the way for targeted therapeutic options for patients with CIPO.

    Percutaneous gastrostomy is a well-established method of providing enteral nutrition to patients incapable of oral intake, or for whom oral intake is insufficient to meet metabolic needs. In comparison to total parenteral nutrition, enteral feeding is advantageous in that it helps maintain gut mucosal integrity, which decreases the risk of bacterial translocation through the gastrointestinal tract. Complications include bleeding, aspiration, internal organ injury, perforation, periostomal leaks, tube dislodgement, and occlusion. Acute pancreatitis secondary to percutaneous gastrostomy tube migration is rare. We present a patient with acute obstructive pancreatitis secondary to percutaneous gastrostomy tube migration.

    Chronic intestinal pseudo-obstruction results in clinical manifestations that resemble intestinal obstruction but in the absence of any physical obstructive process. Fabry disease is an X-linked lysosomal storage disease characterized by the dysfunction of multiple systems, including significant gastrointestinal involvement. We report the occurrence of chronic intestinal pseudo-obstruction in two unrelated patients with Fabry disease and the possible explanation of a direct relation of these two disorders. In Fabry disease, gastrointestinal symptoms occur in approximately 70% of male patients, but the frequency ranges from 19% to 69% in different series. In some patients, colonic dysmotility due glycolipid deposition in autonomic plexus and ganglia can lead to the pseudo-obstruction syndrome, simulating intestinal necrosis. That is why up to this date colostomy has been performed in some cases, even for children with FD without cardiac, renal or cerebrovascular compromise. Early treatment with enzyme replacement therapy in asymptomatic or mildly symptomatic patients may be justified in order to prevent disease progression. Several studies have demonstrated that enzyme replacement therapy alleviates GI manifestations. Because of the non-specific nature of the gastrointestinal symptoms, diagnosis of Fabry disease is often delayed for several years. Gastrointestinal involvement is often misdiagnosed or under-reported. It is therefore very important to consider Fabry disease in the differential diagnosis of chronic intestinal pseudo-obstruction.

    Strangulation colorectal obstruction was modeled in 60 Wistar rats. Necrotic segment of the intestine was resected under conditions of peritonitis and end-to-end intestinal anastomosis was performed on a PCV catheter conducted through the anus. Sodium hypochlorite and ozone solution were used for sanitation of the abdominal cavity and intestinal lavage, and the intestinal anastomosis was coated with Ozonide (ozonized oil). The use of physicochemical methods notably reduced the incidence of postoperative pyoinflammatory complications, incompetence of intestinal anastomosis sutures, and animal mortality.

    Primary internal hernias are extremely rare in adults. They are an important cause of small intestinal obstruction and lead to high morbidity and mortality if left untreated. Clinical presentation of internal hernia is nonspecific. Imaging has been of limited utility in cases of acute intestinal obstruction; moreover, interpretation of imaging features is operator dependant. Thus, internal hernias are usually detected at laparotomy and preoperative diagnosis in an emergency setting is either difficult or most of the time not suspected. We report herein a case of a 45-year-old male who presented with acute intestinal obstruction which was attributed later to a very rare type of internal hernia on exploratory laparotomy. A loop of ileum was found to enter the retroperitoneum through a hernia gate which was located lateral to the sigmoid colon in the left paracolic gutter. The segment of intestine was reduced and the hernial defect was closed. Our finding represents an extremely rare variant of retroperitoneal hernias. PMID:27999703

    In a retrospective study the authors analyzed the clinical records of 199 children ages one month to 16 years hospitalized, with the diagnosis of intestinal ascariasis, in the Instituto Nacional de Pediatria of Mexico from 1984 to 1999. The purpose of the study was to evaluate the use of anthelmintics drugs as a risk factor of intestinal obstruction by A. lumbricoides. Two groups were made for the study: Group A (n = 66) of children who presented intestinal obstruction, Group B (n = 133) children with no complications. A comparative analysis of clinical data of both groups was made by means of chi square with Yates correction and a stratified analysis by means of chi square. Possible confusing elements were overcrowding, age and the use of antiparasitic drugs. The calculus of risk factors for intestinal obstruction by A. lumbricoides was done by means of contingency tables of 2 x 2 and odds ratio with an IC of 95%. The significant risk factors were included in a model of logistics regression with an impact variable consting in the presence or absence of intestinal obstruction in order to establish a multivariate model of predictive risk at level of significance of p < 0.05. Twenty-seven patients (40.90%) in group A (n = 66) were given anthelmintics medications prior to the intestinal obstruction: mebendazol, 14 (51-85%); two, albedazol (7.4%); eight, a non-specified anthelmintic (29.6%). In addition, an anthelmintic medication without a specified time of ingestion: two with mebendazol and one with piperazine (11.3%). In the case of mebendazol, the drug most frequently associated with intestinal obstruction, seven patients received it on the same day of the obstruction; five patients received it between one and seven days prior to the obstruction; two received it seven days prior to the complication. In the control group, only 7% had taken the anthelmintic one to seven days before the diagnosis of uncomplicated intestinal ascariasis diagnosis was made. With the step

    AIM: To observe the protective effect of glucagon-like peptide-2 (GLP-2) on the intestinal barrier of rats with obstructive jaundice and determine the possible mechanisms of action involved in the protective effect. METHODS: Thirty-six Sprague-Dawley rats were randomly divided into a sham operation group, an obstructive jaundice group, and a GLP-2 group; each group consisted of 12 rats. The GLP-2 group was treated with GLP-2 after the day of surgery, whereas the other two groups were treated with the same concentration of normal saline. Alanine aminotransferase (ALT), total bilirubin, and endotoxin levels were recorded at 1, 3, 7, 10 and 14 d. Furthermore, on the 14th day, body weight, the wet weight of the small intestine, pathological changes of the small intestine and the immunoglobulin A (IgA) expressed by plasma cells located in the small intestinal lamina propria were recorded for each group. RESULTS: In the rat model, jaundice was obvious, and the rats’ activity decreased 4-6 d post bile duct ligation. Compared with the sham operation group, the obstructive jaundice group displayed increased yellow staining of abdominal visceral serosa, decreased small intestine wet weight, thinning of the intestinal muscle layer and villi, villous atrophy, uneven height, fusion, partial villous epithelial cell shedding, substantial inflammatory cell infiltration and significantly reduced IgA expression. However, no significant gross changes were noted between the GLP-2 and sham groups. With time, the levels of ALT, endotoxin and bilirubin in the GLP-2 group were significantly increased compared with the sham group (P < 0.01). The increasing levels of the aforementioned markers were more significant in the obstructive jaundice group than in the GLP-2 group (P < 0.01). CONCLUSION: GLP-2 reduces intestinal mucosal injuries in obstructive jaundice rats, which might be attributed to increased intestinal IgA and reduced bilirubin and endotoxin. PMID:25593463

    Abstract Ventriculoperitoneal (VP) shunt complications are common, but abdominal complications are rare. The objective of this report is to present 2 cases of intestinal obstruction due to a VP shunt and review the literature for data on this rare occurrence. A 4-month-old boy received surgical resection of a medulloblastoma and a VP shunt was inserted to manage progressive hydrocephalus. Two months later, he was admitted with intermittent vomiting, and plain abdominal radiography showed complete intestinal obstruction. Emergency laparotomy revealed an adhesive intestinal obstruction around the catheter, and approximately 5 cm of necrotic ileum was resected. His recovery was uneventful. In the second case, a 6-year-old boy was diagnosed with a primary nongerminomatous malignant germ cell tumor and a VP shunt was place to treat hydrocephalus. Two weeks after the first course of chemotherapy, he went into a coma; computed tomography demonstrated enlargement of the tumor and gross total resection was performed. Two weeks later, he developed abdominal distention; plain radiography showed intestinal obstruction and laparotomy revealed adhesive intestinal obstruction around the catheter with 15 cm of necrotic ileum. The necrotic bowel was resected. Unfortunately, the patient developed sepsis and despite treatment remained in a vegetative state. Medline, Central, Embase, and Google Scholar databases were searched up to May 9, 2014, using the terms VP shunt, shunting, and/or intestinal obstruction. Only cases involving children or adolescents were included. Eleven reports involving patients with abdominal complications resulting from a VP shunt for hydrocephalus were identified. The dates of the reports spanned from 1971 to 2014. Volvulus was the most common cause of VP shunt-related obstruction, and mechanical obstruction due to twisting of the catheter the second most common. Only 1 case in the literature review was related to intestinal adhesions. Treatment in most

    ABSTRACT Strangulated intestinal obstruction is one of the most common types of acute abdomen and requires urgent surgical treatment. Herein, we report a very rare case of strangulated intestinal obstruction caused by an ileo-ileal knot. An 80-year-old woman was admitted to our hospital with suspicion of strangulation ileus and underwent emergency laparotomy after investigation by exploratory single-port laparoscopy. During surgery, a small bowel gangrene caused by an ileo-ileal knot was found. The gangrenous segment was resected, and primary anastomosis was performed. Post-operative recovery was uneventful except for a minor wound infection. Our extensive search of the literature found only 7 case reports of ileo-ileal knot including ours. An ileo-ileal knot should be considered in the differential diagnosis of acute intestinal obstruction, because this rare phenomenon requires urgent surgical treatment; and some complications should be considered during or after surgery.

    Intestinal pseudo-obstruction is a clinical syndrome in which the clinical symptoms of intestinal obstruction appear without mechanical obstruction of the intestine. We searched for articles from Japana Centra Revuo Medicina for the period 1983-2009 using the keywords 'chronic' and 'intestinal pseudo-obstruction'. 124 articles were identified, and of these 121 cases were investigated using our diagnostic criteria. The patients were between 0 (just after birth) and 84 years of age, indicating that chronic intestinal pseudo-obstruction (CIP) can occur at any age. The mean age was 43.6 years and the median age was 47 years. Forty-nine patients were male and 72 were female, showing a slight tendency towards female predominance. Five cases (4.2%) had a definitive family history. Of the identified causes of secondary CIP, systemic sclerosis was the most common. Abdominal bloating was the most common initial symptom, seen in 90 (81%) patients. Patients having poor intestinal peristalsis with stagnation of the contents of the small intestines causing fatty stools and bacterial overgrowth complained of diarrhea. The interval between the initial symptoms and diagnosis ranged from 0 to 60 years, with a mean and median interval of 7.3 and 2 years, respectively. In case reports of CIP in Japan, the sensitivity of our diagnostic criteria was found to be 85.9%, indicating that the criteria are useful. For improvement in the rate of recognition of CIP and practical application of the diagnostic criteria in Japan, it is important to conduct further studies.

    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.

    Partial obstruction of the small intestine causes obvious hypertrophy of smooth muscle cells and motility disorder in the bowel proximate to the obstruction. To identify electric remodeling of hypertrophic smooth muscles in partially obstructed murine small intestine, the patch-clamp and intracellular microelectrode recording methods were used to identify the possible electric remodeling and Western blot, immunofluorescence and immunoprecipitation were utilized to examine the channel protein expression and phosphorylation level changes in this research. After 14 days of obstruction, partial obstruction caused obvious smooth muscle hypertrophy in the proximally located intestine. The slow waves of intestinal smooth muscles in the dilated region were significantly suppressed, their amplitude and frequency were reduced, whilst the resting membrane potentials were depolarized compared with normal and sham animals. The current density of voltage dependent potassium channel (KV) was significantly decreased in the hypertrophic smooth muscle cells and the voltage sensitivity of KV activation was altered. The sensitivity of KV currents (IKV) to TEA, a nonselective potassium channel blocker, increased significantly, but the sensitivity of IKv to 4-AP, a KV blocker, stays the same. The protein levels of KV4.3 and KV2.2 were up-regulated in the hypertrophic smooth muscle cell membrane. The serine and threonine phosphorylation levels of KV4.3 and KV2.2 were significantly increased in the hypertrophic smooth muscle cells. Thus this study represents the first identification of KV channel remodeling in murine small intestinal smooth muscle hypertrophy induced by partial obstruction. The enhanced phosphorylations of KV4.3 and KV2.2 may be involved in this process.

    We describe the clinicopathologic characteristics of three patients with chronic intestinal pseudo-obstruction and malabsorption. The patients were young women (average age, 25 years) who presented with abdominal pain, nausea, vomiting, diarrhea, and weight loss that led to extreme inanition and death in two patients despite multiple treatment schemes. The evolution of the process averaged 8 years. No case manifested evidence of malignant lymphoproliferative progression. Histologically, a diffuse lymphoplasmacytic infiltrate that affected all the layers of the intestinal wall was observed in full-thickness biopsy specimens. The proliferating lymphocytes were small and mixed with mature plasma cells that proved to be polyclonal on immunohistochemical analysis. An outstanding finding in all three cases was extensive damage to submucosal and myenteric nerve plexus associated with a lymphoid infiltrate. Quantification of the myenteric plexus by using immunohistochemical and morphometric techniques also revealed a marked reduction in their number. We concluded that diffuse lymphoplasmacytic infiltration of the small intestine associated with damage to the intestinal nerve plexus constitutes a specific disorder that is different from other diseases that produce intestinal pseudo-obstruction.

    Presented are the results of experimental research on 144 animals (the rats Wistar), on whom was carried out resection of a part of large intestine and a intestinal anastamosis was formed in the presents of acute intestinal obstruction and peritonitis. The sanitation of abdominal cavity in the basic group of animals (74) was performed using sodium hypochlorite solution and dissolved ozone. The intestinal lavage was carried out by dissolved ozone with the subsequent introduction of ozonized oil Ozonide in the area of intestinal anastamosis. The combined application of ozone and sodium produces an expressed samative effect which leads to healing of intestinal anastamosis and decreases unstability of intestinal sutures and mortality.

    Patient: Male, 14 Final Diagnosis: Duodenal obstruction Symptoms: Bilious vomiting Medication: None Clinical Procedure: Laparotomy Specialty: Surgery Objective: Rare disease Background: In patients with intestinal malrotation, the diagnosis of acute appendicitis can be difficult due to atypical presentation. Duodenal obstruction caused by acute appendicitis with the presence of malrotation has rarely been reported in children. Case Report: We report the case of a 14-year-old male patient with bilious vomiting and abdominal distension. A diagnosis could not be made by computed tomography, ultrasonography, or endoscopy. We observed a dilated stomach and malrotation in laparotomy. The caecum was in the right upper quadrant, and an inflamed appendix was located in the subhepatic region. After the appendectomy, the cecum was mobilized and fixed in the right lower quadrant. Conclusions: In children with intestinal malrotation, acute appendicitis can present as duodenal obstruction without abdominal pain, and standard imaging methods can miss the correct diagnosis.

    We present three cases of self-expandable metallic stent (SEMS) placement using a balloon enteroscope (BE) and its overtube (OT) for malignant obstruction of surgically reconstructed intestine. A BE is effective for the insertion of an endoscope into the deep bowel. However, SEMS placement is impossible through the working channel, because the working channel of BE is too small and too long for the stent device. Therefore, we used a technique in which the BE is inserted as far as the stenotic area; thereafter, the BE is removed, leaving only the OT, and then the stent is placed by inserting the stent device through the OT. In the present three cases, a modification of this technique resulted in the successful placement of the SEMS for obstruction of surgically reconstructed intestine, and the procedures were performed without serious complications. We consider that the present procedure is extremely effective as a palliative treatment for distal bowel stenosis, such as in the surgically reconstructed intestine.

    Chronic intestinal pseudo-obstruction (CIPO) is a rare disorder characterized by a severe impairment of gastrointestinal propulsion in the absence of mechanical obstruction. We experienced a case of chronic pseudo-obstruction in the initial phase mimicking acute pseudo-obstruction, which was treated medically. This ongoing case was compared to another recurrent and intractable case successfully treated with surgery and diagnosed as hypoganglionosis. These two cases showed different clinical features and therapeutic approaches for CIPO; one with the first episode of CIPO mimicking Ogilvie's syndrome; the other with recurrent episodes of CIPO with typical features. In conclusion, CIPO is a difficult disorder with various clinical manifestations and different treatment modalities, therefore individualized diagnostic and therapeutic approaches are needed.

    Introduction. Femoral hernias are at high risk of strangulation due to the narrow femoral canal and femoral ring. This can lead to symptoms of obstruction or strangulation requiring emergency surgery and possible bowel resection. To our knowledge, there is only one previous published report of bilateral strangulated femoral hernia. We present our case of this phenomenon. Case Report. An 86-year-old woman presented with symptoms of small bowel obstruction. Examination revealed two tender lumps in the area of the femoral triangle. CT scan revealed bilateral femoral hernias. Both hernias were repaired and a small bowel resection on the right side was performed with side to side anastomosis. She made an uneventful recovery. Conclusion. Bilateral femoral hernias are a rare occurrence with only one reported case of bilateral strangulation. Our case highlights the importance of meticulous history taking and clinical examination as any delay in diagnosis will increase the risk of mortality and morbidity for the patient. Hernias should always be considered as a cause if one presents with symptoms of abdominal pain or obstruction. PMID:25057426

    The purpose of this study was to determine whether nitric oxide (NO) is present in clinically normal horses under basal conditions and if it increases secondary to naturally acquired small intestinal strangulation obstruction. Thirty-one horses were used; 20 horses with naturally acquired small intestinal strangulation obstruction and 11 clinically normal horses with no signs of gastrointestinal tract disease. Jugular venous blood, abdominal fluid, and urine were collected for NO quantification. Plasma, abdominal fluid, and urine were stored at -70 degrees C until analyzed for NO using a chemiluminescent method. Biopsy specimens collected from the affected jejunal segment, during anesthesia or after immediately after euthanasia, or from the midjejunum of control horses, were divided into subsections for fixation in zinc formalin and cryopreservation in OCT gel. Nicotinamide adenine dinucleotide phosphate (reduced) (NADPH) diaphorase histochemical stains were performed on cryopreserved tissues and inducible nitric oxide synthase (iNOS) and nitrotyrosine immunohistochemical stains were performed on formalin-fixed, paraffin-embedded tissues. There were significantly greater plasma and abdominal fluid NO concentrations in affected horses as compared with controls, but there were no significant differences between horses for urine NO concentrations. There was a significant decrease in NADPH diaphorase stain in mucosal epithelium, vasculature, and leukocytes, and in submucosal plexi in affected horses compared with control horses. There was a significant increase in iNOS staining in mucosal and submucosal leukocytes and in mucosal leukocyte nitrotyrosine staining of the affected compared with control horses. Endothelial NOS and neuronal NOS are present under basal conditions in the jejunum of horses and probably mediate physiologic or cytoprotective effects. Plasma and abdominal fluid, but not urine, NO concentrations increase subsequent to small intestinal strangulation

    Background Intestinal atresia is a rare congenital disorder with an incidence of 3/10 000 birth. About one-third of patients have severe intestinal dysfunction after surgical repair. We examined whether prenatal gastrointestinal obstruction might effect on the myenteric plexus and account for subsequent functional disorders. Methodology/Principal Findings We studied a rat model of surgically induced antenatal atresia, comparing intestinal samples from both sides of the obstruction and with healthy rat pups controls. Whole-mount preparations of the myenteric plexus were stained for choline acetyltransferase (ChAT) and nitric oxide synthase (nNOS). Quantitative reverse transcription PCR was used to analyze mRNAs for inflammatory markers. Functional motility and permeability analyses were performed in vitro. Phenotypic studies were also performed in 8 newborns with intestinal atresia. In the experimental model, the proportion of nNOS-immunoreactive neurons was similar in proximal and distal segments (6.7±4.6% vs 5.6±4.2%, p = 0.25), but proximal segments contained a higher proportion of ChAT-immunoreactive neurons (13.2±6.2% vs 7.5±4.3%, p = 0.005). Phenotypic changes were associated with a 100-fold lower concentration-dependent contractile response to carbachol and a 1.6-fold higher EFS-induced contractile response in proximal compared to distal segments. Transcellular (p = 0.002) but not paracellular permeability was increased. Comparison with controls showed that modifications involved not only proximal but also distal segments. Phenotypic studies in human atresia confirmed the changes in ChAT expression. Conclusion Experimental atresia in fetal rat induces differential myenteric plexus phenotypical as well as functional changes (motility and permeability) between the two sides of the obstruction. Delineating these changes might help to identify markers predictive of motility dysfunction and to define guidelines for post-surgical care. PMID:23667464

    Chronic intestinal pseudo-obstruction (CIPO) is a rare intestinal motility disorder with significant morbidity and mortality in pediatric patients. The diagnosis of CIPO is difficult, because it is clinically based on the symptoms and signs of bowel obstruction which are similar to the clinical manifestations of other gastrointestinal diseases like short bowel syndrome (SBS). Therefore, it is desirable to identify and establish new laboratory diagnostic markers for CIPO that are reliable and easily accessible. In our study we have identified the ratio of the urinary glutamine and glutamic acid as a promising biomarker for distinguishing suspected CIPO cases and simple SBS cases. The area under ROC curve was 0.83, at cutoff value = 7.04 with sensitivity of 65% and specificity of 92%.

    Chronic intestinal pseudo-obstruction (CIPO), a rare, debilitating disorder of bowel motility dysfunction, is largely a clinical diagnosis, without any universally accepted diagnostic criteria. Three subgroups are generally acknowledged based on the cell-type affected: enteric visceral myopathy (the most common subgroup), neuropathy, and mesenchymopathy. A fourth subgroup includes abnormalities of neurohormonal peptides. Although immunohistochemical staining is reportedly useful for identifying the mesenchymopathic type, its role in diagnosing enteric visceral myopathy and neuropathy has been fraught with difficulties. We present two cases of chronic intestinal pseudo-obstruction that are clinically and histopathologically suggestive of type III visceral enteric myopathy, aiming to expound upon the diagnostic and pathogenic features. We found that the outer-longitudinal layer of the muscularis propria was more severely affected as compared with the inner circular layer. To investigate the value of this finding, we performed immunostains in the one case in which a paraffin block was available. We found increased peripherin and calretinin immunopositive nerve fibers in the outer layer as compared with inner, but without any significant increase in S-100 positivity or alteration in neuronal morphology of myenteric plexus, a novel finding. This differential staining pattern was completely different from Hirschsprung disease, in which we found rare to absent peripherin and calretinin staining. It is unclear if this increase in the outer layer in visceral myopathy reflects a reactive change or dysfunctional axons. In addition, the history of volvulus in one patient and transmural inflammatory changes in the second raise concerns about the higher propensity of clinical complications secondary to the attenuated outer muscular layer. This study suggests that enteric visceral myopathy has histologic and staining characteristics different from Hirschsprung disease, a finding

    Background. Acute intestinal obstruction during pregnancy is a very challenging and unusual nonobstetric surgical entity often linked with considerable fetomaternal morbidity and mortality. When it is synchronous with abdominal pregnancy, it is even rarer. Case Presentation. A 28-year-old lady in her second pregnancy was referred to Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria, at 27 weeks of gestation due to vomiting, constipation, and abdominal pain. Examination and ultrasound scan revealed a single live intra-abdominal extrauterine fetus. Plain abdominal X-ray was diagnostic of intestinal obstruction. Conservative treatment was successful till the 34-week gestational age when she had exploratory laparotomy. At surgery, the amniotic sac was intact and the placenta was found to be adherent to the gut. There was also a live female baby with birth weight of 2.3 kg and Apgar scores of 9 and 10 in the 1st and 5th minutes, respectively, with the baby having right clubbed foot. Adhesiolysis and right adnexectomy were done. The mother and her baby were well and were discharged home nine days postoperatively. Conclusion. To the best of our knowledge, this is the first report of abdominal pregnancy as the cause of acute intestinal obstruction in the published literature. Management approach is multidisciplinary.

    Background: Gastrointestinal tract (GIT) duplications are one of the rare congenital anomalies and can occur in any portion of the gastrointestinal tract but are more commonly encountered in small intestine. The duplication cysts cause symptoms like abdominal mass and intestinal obstruction requiring surgery or may remain asymptomatic. We are reporting our 15 years’ experience duplication cysts presenting in neonates. Methods: It is a retrospective study undertaken in the department of pediatric surgery between 2001 and 2015 for GIT duplications in neonates. Patients were analyzed for their antenatal diagnosis, age, sex, clinical diagnosis, investigatory approach, operative management and surgical outcomes. Results: Total number of neonates, diagnosed with gastrointestinal duplication in the last 15 years, was 17. Male to female ratio was 3.3:1. The most common location was found to be the ileum occurring in 71% of cases. Apart from ileum, 2 cases of duodenal and 1 case each of gastric, colonic and cecal duplication cyst were encountered. Majority cases presented with sub-acute intestinal obstruction and were managed successfully by resection and end to end anastomosis. Associated gut atresia was found in 4 cases while 1 case was found to be associated with perforation of gut. Conclusion: Gastrointestinal tract duplications often present with typical symptoms of gastrointestinal tract obstruction. Early diagnosis and management is required to prevent postoperative morbidity and mortality. PMID:28083491

    INTRODUCTION Internal abdominal hernias are infrequent but an increasing cause of bowel obstruction still often underdiagnosed. Among adults its usual causes are congenital anomalies of intestinal rotation, postsurgical iatrogenic, trauma or infection diseases. PRESENTATION OF CASE We report the case of a 63-year-old woman with history of chronic constipation. The patient was hospitalized for two days with acute abdominal pain, abdominal distension and inability to eliminate flatus. The X-ray and abdominal computerized tomography scan (CT scan) showed signs of intestinal obstruction. Exploratory laparotomy performed revealed a trans-mesenteric hernia containing part of the transverse colon. The intestine was viable and resection was not necessary. Only the hernia was repaired. DISCUSSION Internal trans-mesenteric hernia constitutes a rare type of internal abdominal hernia, corresponding from 0.2 to 0.9% of bowel obstructions. This type carries a high risk of strangulation and even small hernias can be fatal. This complication is specially related to trans-mesenteric hernias as it tends to volvulize. Unfortunately, the clinical diagnosis is rather difficult. CONCLUSION Trans-mesenteric internal abdominal hernia may be asymptomatic for many years because of its nonspecific symptoms. The role of imaging test is relevant but still does not avoid the necessity of exploratory surgery when clinical features are uncertain. PMID:24880799

    Introduction. Vitelline artery remnants are rare causes of intra-abdominal bands leading to bowel obstruction. These bands may be associated with Meckel's diverticulum. Double inferior vena cava (IVC) is a rare presentation and is usually identified incidentally. Case Presentation. A sixty-year-old male presented with progressive vomiting for five days and he was clinically diagnosed with intestinal obstruction. Plain X-ray abdomen showed evidence of small bowel obstruction. CT scan of the abdomen revealed dilated small bowel loops with a small outpouching in the distal ileum with a band like structure attached to it. In the CT, left sided patent IVC draining into the left renal vein was identified. Left external iliac vein was in continuity with the left IVC. Left internal iliac vein was draining into the right IVC. Exploratory laparotomy revealed a Meckel's diverticulum with a band identified as the vitelline remnant attached to its apex and inserting at the anterior abdominal wall near the umbilicus. Discussion. Meckel's diverticulum with vitelline bands, although rare, should be borne in mind in adult patients with intestinal obstruction. Identification of this anomaly can be difficult in imaging studies. Presence of double IVC should be mentioned in the imaging findings to prevent possible catastrophic complications during surgery.

    Increased amounts of intestinal endotoxin are absorbed in obstructive jaundice. The precise mechanism is not known but the increased absorption may arise from alterations in the luminal contents, in the intestinal flora, in the gut wall or in interactions between all three. To examine the effects of the intestinal flora we have compared the morphological changes in the small intestine in obstructive jaundice in germ free and conventional rats while the effects of bile constituents have been examined by addition of bile constituents to the diet of bile duct ligated rats. Changes in the intestine were examined, histologically, by enzyme histochemistry, and by transmission and scanning electron microscopy. The results showed no differences in response between germ free and conventional rats. Feeding of diets containing bile salts exacerbated the lesion. Feeding of diets containing cholesterol, however, reduced the degree of intestinal changes produced by cholestasis and completely antagonised the increase in damage caused by feeding of bile salts.

The causes for secondary PUJ obstruction were post-pyelolithotomy in one case, post-pyeloplasty and ureterocalycostomy for PUJ obstruction in the second patient and the third patient had long upper ureteric stricture post-ureteropyeloplasty due to tuberculosis. In all these cases ureterocalycostomy proved to be salvage/final resort for preserving functional renal unit.

  16. Intestinal obstruction due to dual gastrointestinal atresia in infants: diagnosis and management of 3 cases

    PubMed Central

    2014-01-01

    Background Several types of congenital lesions can cause complete or incomplete obstruction of the intestine. Our purpose is to present 3 neonates with dual intestinal type I atresia, i.e., simultaneous obstructive lesions at 2 locations in which the atresia manifested as diaphragm-like tissue. Case presentation All 3 cases were female infants ranging in age from 2 to 14 months. The common symptom in all cases was intermittent persistent vomiting. In some cases the vomitus was bilious, and other symptoms included abdominal distention and delayed meconium passage. Prior surgeries at another hospital were unsuccessful at relieving the symptoms in one case. One case had dual lesions in the colon, one dual lesions in the duodenum, and one atresia at both the distal portion of the ileum and the descending colon. Surgical exploration and removal of the lesions at our hospital was successful in all cases, and the infants were discharged in good condition. Conclusions Type I atresia can manifest as a diaphragm-like tissue obstructing the continuity of gastrointestinal tract, and in rare cases multiple areas may be present. Base on the intermittent nature of the associated symptoms, diagnosis can be difficult and is often delayed. Physicians should be aware of this condition during the work-up of an infant with persistent intermittent vomiting. PMID:24928109

    Chronic intestinal pseudo obstruction (CIPO) is a rare clinical entity characterized by symptoms and signs of intestinal obstruction without either recognizable anatomical abnormalities or intestinal aganglionosis. A Chinese female infant presented to our institution with a clinical diagnosis of CIPO. Aganglionosis was ruled out by full thickness colonic and ileal biopsies and by rectal suction biopsies. Unexpectedly, direct sequencing and PCR amplification of RET proto-oncogene from peripheral blood extracted DNA identified a RET R114H mutation. This mutation has already been reported as strongly associated with Asian patients affected by Hirschsprung's disease (HSCR) and is considered a founder mutation in Asia. The same mutation has never been reported in patients with CIPO, so far. These findings support the role of RET in the development of the enteric nervous system but underline the importance of other genetic or environmental factors contributing to the gastrointestinal phenotype of the disease. Somehow, this RET R114H mutation proved to have a role in the etiology of both CIPO and HSCR and could contribute to a more diffuse imbalance of gut dysmotility. © 2016 Wiley Periodicals, Inc.

It has been used successfully to treat acute and chronic intestinal pseudo-obstructions (CIPs) in adults, but there is a paucity of literature surrounding the treatment of CIP in pediatric patients and therapies for CIP are limited and their impact is often unsatisfactory. This case report presents the use of cisapride in the management of pseudo-obstruction. Treatment with cisapride substantially improved the patient's symptoms and improved feeding tolerance. It improved his prognosis remarkably and prevented the need for end-of-life care. He experienced no adverse effects throughout the course of therapy. The treatment regimen is discussed in this case report.

    This case series examines the safety and efficacy of uterine artery embolization (UAE) in the treatment of obstructive nephropathy caused by large fibroids. Between 2004 and 2007, 10 patients referred with symptomatic uterine fibroids that were found to be causing either unilateral (7 patients) or bilateral (3 patients) hydronephrosis were treated by UAE. Presenting complaints included menorrhagia, dysmenorrhea, bulk symptoms, loin pain, postobstructive atrophy, and mild renal impairment. All had posterior intramural dominant fibroids >11 cm in maximum sagittal diameter and uterine volumes between 3776 and 15,625 ml. Outcome measures at between 12 and 36 months included procedural success, repeat intervention, relief of symptoms, resolution of hydronephrosis, stable renal function and size, and avoidance of hysterectomy. In all cases the cause of renal obstruction was confirmed to be a giant fibroid compressing the ureter at the pelvic brim. In all cases UAE was technically successful, though two patients required a repeat procedure. In eight patients hydronephrosis resolved and the obstruction was relieved, though two still had some bulk symptoms not requiring further treatment. Renal function improved or was stable in all cases. Renal size was stable in all cases. Where menorrhagia was part of the symptom complex it was relieved in all cases. Two patients diagnosed as having postobstructive atrophy of one kidney underwent retrograde ureteric stenting on the nonatrophied side prior to UAE. This was unsuccessful in one of the cases due to the distortion caused by the fibroid. Despite improvement in hydronephrosis this patient underwent hysterectomy at 7 months after a renogram demonstrated persistent obstruction at the pelvic brim. In the second patient a double pigtail stent was inserted with difficulty and eventually removed at 8 months. This patient has had stable renal function and size for 3 years post-UAE. We conclude that UAE is safe and effective in

    A 64-year-old woman was hospitalized at an internal care unit, due to growing weakness, dizziness, lack of appetite, anemia and abdominal pain. In anamnesis: past myocardial infarction, post-operative hypothyroidism, type 2 diabetes insulin-dependent, stroke, left kidney cirrhosis, gout and anemia. The physical examination did not reveal pathological changes except for skin paleness. The biochemical tests showed iron deficiency anemia and elevated Ca 125 (54.5 U/ml) (normal range: 0.00–35.00). Other markers were normal. An abdominal CT revealed a bifocal infiltration of the small intestine. Due to the increasing obstruction symptoms, the patient was operated on. A bifocal small bowel tumor was found intra-surgically. A partial resection of the jejunum and distal ileum was made. The intestines were joined end to end. The histopathological diagnosis corresponded to metastases of malignant melanoma. The postoperative course was uncomplicated. She received two cycles of dacarbazine 1000 mg/day. Due to drug intolerance, the chemotherapy was discontinued. Now, she is receiving hospice care. PMID:24596522

    Intestinal pseudo-obstruction (IpsO) and acute lupus pneumonitis (ALP) are uncommon severe complications of systemic lupus erythematosus (SLE). The present study reports the case of a 26-year-old female who presented with abdominal pain, nausea and vomiting as initial symptoms. Computed tomography (CT) scanning revealed the jejunal wall was thickened and streaky, mimicking the presentation of intestinal obstruction. Following emergency surgery, the patient's general condition was aggravated, with evident limb erythematous rashes. A series of laboratory examinations revealed SLE, and combined with patient's medical history IpsO was diagnosed, with a disease Activity Index score of 10. During the therapeutic period, high fever, dyspnea and oxygen saturation (SaO2) reductions were detected, and CT scans indicated lung infiltration, excluding other causes through a comprehensive infectious work-up and a bronchoalveolar lavage examination. ALP was confirmed and treated with high-dose methylprednisolone and gamma globulin supplement. The patient responded well and was discharged in 2 weeks. In the one-year tapering period and after stopping corticosteroids, the patient recovered well with no relapse detected. In conclusion, the manifestation of IpsO in SLE is rare and represents a challenge for the surgeon to establish the correct diagnosis and avoid inappropriate surgical intervention. ALP may be the consequence of emergency surgery, and immediate high-dose glucocorticoid therapy is recommended. PMID:27347044

    Extraskeletal osteosarcoma (ESOS) is an uncommon tumor that accounts for 1% of all soft tissue sarcomas and 4% of all osteosarcomas. Its presentation may be atypical, while pain has been described as the most common symptom. Radiological findings include a large mass in the soft-tissues with massive calcifications, but no attachment to the adjacent bone or periosteum. We present the case of a 73-year-old gentle man who presented with a palpable, tender abdominal mass and symptoms of bowel obstruction. Computer tomography images revealed a large space-occupying heterogeneous, hyper dense soft tissue mass involving the small intestine. Explorative laparotomy revealed a large mass in the upper mesenteric root of the small intestine, measuring 22 cm × 12 cm × 10 cm in close proximity with the cecum, which was the cause of the bowel obstruction. Pathology confirmed the diagnosis of an ESOS. ESOS is an uncommon malignant soft tissue tumor with poor prognosis and a 5-year survival rate of less than 37%. Regional recurrence and distant metastasis to lungs, regional lymph nodes and liver can occur within the first three years of diagnosis in a high rate (45% and 65% respectively). Wide surgical resection of the mass followed by adjuvant chemotherapy or radiotherapy has been the treatment of choice. PMID:28289512

    Introduction. Intussusception is a rare clinical entity in adults (<1% of intestinal obstructions). Colonic intussusception is even rarer, particularly when caused by lipomas. Case Presentation. A 47-year-old woman presented to our emergency department complaining of abdominal pain with vomiting and diarrhoea. X-ray and CT showed bowel obstruction due to ileocolonic and colocolonic intussusception; a giant colonic lipoma (9 × 4 × 4 cm) was recognizable immediately distally to the splenic flexure of the colon. The patient underwent emergency laparotomy and right hemicolectomy. Assessment of the resected specimen confirmed the diagnosis of giant colonic polypoid lesion near to the ileocecal valve, causing a 12 cm long intussusception with moderate ischemic damage. Conclusion. Colonic obstruction due to intussusception caused by lipomas is a very rare condition that needs urgent treatment. CT is the radiologic modality of choice for diagnosis (sensitivity 80%, specificity near 100%); since the majority of colonic intussusceptions are caused by primary adenocarcinoma, if the etiology is uncertain, the lesion must be interpreted as malignant and extensive resection is recommended. At present, surgery is the treatment of choice and determines an excellent outcome. PMID:28044120

    Obstructive azoospermia constitutes 35 to 40% of azoospermia. Etiologies may be acquired or rarely congenital. Congenital utricular or Mullerian duct cyst may result in compression of ejaculatory ducts. However, they must be differentiated from exceptional wolffian or urogenital cysts, which are located at the same site but in which ejaculatory ducts may drain inside. We report a case of retroprostatic duct cyst diagnosed during work up of male infertility where magnetic resonance imaging (MRI) showed the drainage of both ejaculatory ducts inside and the presence of a thin canal ended blindly in the wall of prostatic urethra. Transurethral resection guided by MRI has been performed resulting in urethral drainage of the cyst, relieving of obstruction and normalization of spermogramm.

    A 10-year old Lhasa Apso dog was presented for an acute history of exercise intolerance and hind limb weakness. High grade second degree atrioventricular block with an atrial rate of 200 beats per minute, ventricular rate of 40 beats per minute and an intermittent ventricular escape rhythm, was diagnosed on electrocardiograph. A transdiaphragmatic, unipolar, epicardial pacemaker was implanted without immediate surgical complications. Severe vomiting was noted 12 h post-operatively. Abdominal ultrasound and a barium study supported a diagnosis of pyloric outflow obstruction and exploratory abdominal surgery was performed. The pyloric outflow tract appeared normal and no other causes of an outflow obstruction were identified. The epicardial generator was repositioned from the right to the left abdominal wall. Pyloric cell pacing was presumed to be the cause for the pyloric obstruction and severe vomiting, and this was thought to be due to close proximity of the pacemaker generator to the pylorus situated in the right abdominal wall. Repositioning of the pulse generator to the left abdominal wall resulted in resolution of vomiting.

    Inflammatory abdominal aortic aneurysms (IAAA) represent 3% to 10% of all abdominal aortic aneurysms. Obstructive uropathy is a well-described feature of IAAAs, but venous complications are unusual secondary to IAAA. The authors report a patient presenting with acute renal failure and deep venous thrombosis secondary to an IAAA. We believe this represents the first case of an IAAA manifesting as combined inferior vena cava compression and associated obstructive uropathy. Successful operative repair was performed. With resolution of the retroperitoneal inflammation, long-term follow-up revealed spontaneous release of both ureteral and caval compression.

    Oedema can occur in handled tissues following upper gastrointestinal surgery with anastomosis formation. Obstruction of the lumen may result in delayed return of enteric function. Intravenous steroid use may be beneficial. Three cases of delayed emptying following fundoplication, gastro-enteric and entero-enteric anastomoses are reviewed. Conservative management with supportive measures failed. Dexamethasone was administered to treat the oedematous obstruction. A literature review in PubMed, Cochrane database and Medline for English language publications on the use of dexamethasone in the treatment of acute post surgical oedema of the upper gastrointestinal was conducted. Administration of dexamethasone led to resolution of symptoms and successful outcome. No reports on the use of steroids in this context were identified in the literature. The use of dexamethasone may effectively treat intestinal obstruction due to inflammatory or oedematous cause in the early post-operative period.

    AIMS—To document the long term course of chronic idiopathic intestinal pseudo-obstruction syndrome (CIIPS) in children with defined enteric neuromuscular disease, and the place and type of surgery used in their management; in addition, to identify prognostic factors.
METHODS—Children with CIIPS were investigated and treated prospectively.
RESULTS—Twenty four children presented congenitally, eight during the 1st year of life, and 10 later. Twenty two had myopathy and 16 neuropathy (11 familial). Malrotation was present in 16 patients, 10 had short small intestine, six had non-hypertrophic pyloric stenosis, and 16 had urinary tract involvement. Thirty two patients needed long term parenteral nutrition (TPN): for less than six months in 19 and for more than six months in 13, 10 of whom are TPN dependent; 14 are now enteral feeding. Prokinetic treatment improved six of 22. Intestinal decompression stomas were used in 36, colostomy relieved symptoms in five of 11, and ileostomy in 16 of 31. A poor outcome (death (14) or TPN dependence (10)) was seen with malrotation (13 of 16), short small bowel (eight of nine), urinary tract involvement (12 of 16), and myopathic histology (15 of 22).
CONCLUSIONS—In CIIPS drugs are not helpful but decompression stomas are. Outcome was poor in 24 of 44 children (15 muscle disorder, 10nerve disease).

    In a double-blind, placebo-controlled, crossover trial, we investigated the effects of the prokinetic drug cisapride in patients with cystic fibrosis and chronic recurrent distal intestinal obstruction syndrome (DIOS). After a baseline period, 17 patients (12.9 to 34.9 years; 12 boys) received, in random order, cisapride (7.5 to 10 mg) and placebo three times daily by mouth, each for 6 months. Gastrointestinal symptoms (flatulence, abdominal pain, fullness, abdominal distension, nausea, anorexia, heartburn, diarrhea, vomiting and regurgitation) were scored three times monthly and physical examinations assessed. At baseline and at each 6-month period, assessment included food intake for 7 days, 3-day stool collection, pulmonary function tests, and abdominal radiographs. During cisapride therapy compared with placebo, there were significant reductions in flatulence (p less than 0.005), fullness, and nausea (p less than 0.05). Patients with the worst symptom scores benefited most from cisapride. With cisapride, 12 patients felt better and three worse (p less than 0.05); physicians judged 11 patients improved and two worse (p less than 0.05). No side effects were noted. There were no significant differences between cisapride and placebo periods in nutritional status, x-ray scores, pulmonary function, food intake (fat, protein, calories), stool size and consistency, and fecal losses of fat, bile acids, chymotrypsin, and calories. For acute episodes of DIOS, intestinal lavage was needed 6 times in 4 patients during treatment with cisapride, and 11 times in 6 patients receiving placebo. In comparison with unselected patients with cystic fibrosis and pancreatic insufficiency who were receiving enzyme supplements and who had no distal intestinal obstruction, fecal fat losses (percentage of intake) were almost twice as high in the study group with DIOS (31.2 +/- 20.6% vs 16.2 +/- 17.6%; p less than 0.01). We conclude that in the dosage used, long-term treatment with

    Background & Aims Chronic intestinal pseudo-obstruction (CIPO) is characterized by severe intestinal dysmotility that mimicks a mechanical sub-occlusion with no evidence of gut obstruction. We searched for genetic variants associated with CIPO to increase our understanding of its pathogenesis and indentify potential biomarkers. Methods We performed whole-exome sequencing of genomic DNA from patients with familial CIPO syndrome. Blood and lymphoblastoid cells were collected from patients and controls (individuals without CIPO); levels of mRNA and proteins were analyzed by quantitative reverse transcription PCR, immunoblot, and mobility shift assays. cDNAs were transfected into HEK293 cells. Expression of rad21 was suppressed in zebrafish embryos using a splice-blocking morpholino (rad21a MO). Gut tissues were collected and analyzed. Results We identified a homozygous mutation (p.622, encodes Ala>Thr) in RAD21 in patients from a consanguineous family with CIPO. Expression of RUNX1, a target of RAD21, was reduced in cells from patients with CIPO compared with controls. In zebrafish, suppression of rad21a reduced expression of runx1; this phenotype was corrected by injection of human RAD21 mRNA, but not with the mRNA from the mutated p.622 allele. rad21a MO zebrafish had delayed intestinal transit and greatly reduced numbers of enteric neurons, similar to patients with CIPO. This defect was greater in zebrafish with suppressed expression of ret and rad21, indicating their interaction in regulation of gut neurogenesis. The promoter region of APOB bound RAD21 but not RAD21 p.622 Ala>Thr; expression of wild-type RAD21 in HEK293 cells repressed expression of APOB, compared with control vector. The gut-specific isoform of APOB (APOB48) is overexpressed in sera from patients with CIPO who carry the RAD21 mutation. APOB48 is also overexpressed in sporadic CIPO in sera and gut biopsies. Conclusions Some patients with CIPO carry mutations in RAD21 that disrupt the ability of

    Background/Aims Chronic intestinal pseudo-obstruction (CIPO) is a serious, life-threatening motility disorder that is often related to bacterial overgrowth. Fecal microbiota transplantation (FMT) results in restoration of the normal intestinal microbial community structure. We investigated the efficacy of FMT in the treatment of CIPO patients. Methods Nine patients (age 18–53 years) with CIPO were enrolled in this prospective, open-label study. Patients received FMT for 6 consecutive days through nasojejunal (NJ) tubes and were followed up for 8 weeks after treatment. We evaluated the rate of clinical improvement and remission, feeding tolerance of enteral nutrition, and CT imaging scores of intestinal obstructions. Lactulose hydrogen breath tests were performed before FMT and 8 weeks after FMT to evaluate for the presence small intestinal bacterial overgrowth (SIBO). Results FMT significantly alleviated bloating symptoms, and symptoms of pain were relieved 2 weeks after FMT. Enteral nutrition administered through a NJ tube after FMT was well-tolerated by 66.7% (6/9) of patients. CT scores of intestinal obstructions were significantly reduced after FMT (P = 0.014). SIBO was eliminated in 71.0% (5/7) of patients. Conclusions This pilot study demonstrated the safety of using FMT. FMT may relieve symptoms in selected patients with CIPO. FMT may also improve patient tolerance of enteral nutrition delivered via a NJ tube. PMID:27840368

    A female infant born at 36 weeks gestational age with birthweight 2135 g, and who developed respiratory disorder, hyperlactacidemia and hypertrophic cardiomyopathy after birth, was admitted to hospital at 3 days of age. After admission, bilious emesis, abdominal distention, and passage disorder of the gastrointestinal tract were resistant to various drugs. Exploratory laparotomy was performed at 93 days of age, but no organic lesions were identified and normal Meissner/Auerbach nerve plexus was confirmed, which led to a clinical diagnosis of chronic intestinal pseudo-obstruction (CIPO). She was diagnosed with mitochondrial respiratory chain complex IV deficiency on histopathology of the abdominal rectus muscle and enzyme activity measurement. This is the first report of a neonate with mitochondrial respiratory chain complex deficiency with intractable CIPO. CIPO can occur in neonates with mitochondrial respiratory chain disorder, necessitating differential diagnosis from Hirschsprung disease.

    Visceral myopathy is one of the causes of chronic intestinal pseudo-obstruction. Most cases pathologically reveal degenerative changes of myocytes or muscularis propia atrophy and fibrosis. Abnormal layering of muscularis propria is extremely rare. We report a case of a 9-mo-old Thai male baby who presented with chronic intestinal pseudo-obstruction. Histologic findings showed abnormal layering of small intestinal muscularis propria with an additional oblique layer and aberrant muscularization in serosa. The patient also had a short small bowel without malrotation, brachydactyly, and absence of the 2(nd) to 4(th) middle phalanges of both hands. The patient was treated with cisapride and combined parenteral and enteral nutritional support. He had gradual clinical improvement and gained body weight. Subsequently, the parenteral nutrition was discontinued. The previously reported cases are reviewed and discussed.

    The histopathological approach of chronic intestinal pseudo-obstruction (CIP) is critical, and the findings are often missed by the histopathologists for lack of awareness and nonavailability of standard criteria. We aimed to describe a detailed histopathological approach for working-up cases of CIP by citing our experience. Eight suspected cases of CIP were included in the study to determine and describe an approach for reaching the histopathological diagnosis collected over a period of the last 1.5 years. The Hirschsprung's disease was put apart from the scope of this study. A detailed light microscopic analysis was performed along with special and immunohistochemical stains. Transmission electron microscopy was carried out on tissue retrieved from paraffin embedded tissue blocks. Among the eight cases, three were neonates, one in the pediatric age group, two adolescent, and two adults. After following the described critical approach, we achieved the histological diagnoses in all the cases. The causes of CIP noted were primary intestinal neuronal dysplasia (IND) type B (in 4), mesenchymopathy (in 2), lymphocytic myenteric ganglionitis (in 1), and duplication of myenteric plexus with leiomyopathy (in 1). Desmosis was noted in all of them along with other primary pathologies. One of the IND patients also had visceral myopathy, type IV. Histopathologists need to follow a systematic approach comprising of diligent histological examination and use of immunohistochemistry, immunocytochemistry, and electron microscopy in CIP workup. Therapy and prognosis vary depending on lesions identified by pathologists. These lesions can be seen in isolation or in combinations.

    The retinoblastoma 1 (RB1) tumor suppressor is a critical regulator of cell cycle progression and development. To investigate the role of RB1 in neural crest–derived melanocytes, we bred mice with a floxed Rb1 allele with mice expressing Cre from the tyrosinase (Tyr) promoter. TyrCre+;Rb1fl/fl mice exhibited no melanocyte defects but died unexpectedly early with intestinal obstruction, striking defects in the enteric nervous system (ENS), and abnormal intestinal motility. Cre-induced DNA recombination occurred in all enteric glia and most small bowel myenteric neurons, yet phenotypic effects of Rb1 loss were cell-type specific. Enteric glia were twice as abundant in mutant mice compared with those in control animals, while myenteric neuron number was normal. Most myenteric neurons also appeared normal in size, but NO-producing myenteric neurons developed very large nuclei as a result of DNA replication without cell division (i.e., endoreplication). Parallel studies in vitro found that exogenous NO and Rb1 shRNA increased ENS precursor DNA replication and nuclear size. The large, irregularly shaped nuclei in NO-producing neurons were remarkably similar to those in progeria, an early-onset aging disorder that has been linked to RB1 dysfunction. These findings reveal a role for RB1 in the ENS. PMID:24177421

    Chronic intestinal pseudo-obstruction (CIP) is an infrequent complication of an active systemic lupus erythematosus (SLE). We illustrate a case of SLE inactive-related CIP. A 51-year old female with inactive SLE (ECLAM score 2) was hospitalized with postprandial fullness, vomiting, abdominal bloating and abdominal pain. She had had no bowel movements for five days. Plain abdominal X-ray revealed multiple fluid levels and dilated small and large bowel loops with air-fluid levels. Intestinal contrast radiology detected dilated loops. CIP was diagnosed. The patient was treated with prokinetics, octreotide, claritromycin, rifaximin, azathioprine and tegaserod without any clinical improvement. Then methylprednisolone (500 mg iv daily) was started. After the first administration, the patient showed peristaltic movements. A bowel movement was reported after the second administration. A plain abdominal X-ray revealed no air-fluid levels. Steroid therapy was slowly reduced with complete resolution of the symptoms. The patient is still in a good clinical condition. SLE-related CIP is generally reported as a complication of an active disease. In our case, CIP was the only clinical demonstration of the SLE. PMID:21577309

    Ellis-van Creveld (EVC) syndrome is a rare autosomal recessive disorder characterized by hypoplastic nails, polydactyly, and achondroplasia. Patients usually exhibit normal cognitive function and no remarkable developmental delay. We herein present an unusual case of EVC syndrome. A Japanese 2-year-old boy was born at term, but immediately developed severe respiratory failure due to thorax deformity, postaxial polydactyly and nail hypoplasia. We identified a novel pattern of germinal compound heterozygous nonsense EVC2 mutations of c.1814C > A (p. S605X) and c.2653C > T (p. R885X), leading to the diagnosis of EVC syndrome. Interestingly, he also had severe developmental delay, and suddenly developed excessive abdominal distension at the age of 2. On surgery, extensive necrotic bowel with chronic intestinal pseudo-obstruction was noted. This is, to our knowledge, a most severe phenotype of EVC syndrome, illustrating that the specific pattern of EVC2 compound heterozygous mutations may cause severe developmental delay and intestinal malfunction.

    Abstract Ascaris lumbricoides infection affects approximately 1.5 billion people globally. Children with environmental and socio-economic risk factors are more susceptible to infestation, with serious complications such as intestinal obstruction (IO), volvulus, intussusception, and intestinal necrosis. We present the case of a 3-year-old girl who arrived at emergency department with abdominal pain and diarrhea for the last 3 days. The previous day she took an unspecified anthelmintic. Symptoms worsened with vomiting and diarrhea, with expulsion of roundworms through mouth and anus.

    The mitochondrial neurogastrointestinal encephalomyopathy syndrome (MNGIE) is a rare and life-threatening, autosomal recessive, multisystem disorder, caused by the mutations in the thymidine phosphorylase gene. Herein, we report a case of a 21 year-old male with a long history of intestinal pseudo-obstruction who was diagnosed with MNGIE syndrome after an extensive examination. In this case, our objective was to bring the gastroenterologist's attention to this difficult to diagnose syndrome in the coexistence of intestinal pseudo-obstruction and neurologic manifestations. The patient was a member of a consanguineous family of six children, in whom two sisters had died due to this disorder and one sister was affected and is still alive. The patient presented with cachexia, abdominal pain, diarrhea and muscle weakness, and was previously considered to have gluten sensitive enteropathy and treated with dietary solutions.

    We report a case of non-identical twins who presented with identical neonatal intestinal obstruction with features of anorectal stenosis, presacral mass and sacral anomaly consistent with Currarino's syndrome or triad. Plain sacral radiograph, contrast enema and MRI were diagnostic. Initial management involved a defunctioning colostomy followed by a posterior sagittal anorectoplasty with excision of the teratoma ± anterior sacral meningocele and finally closure of colostomy in a staged multidisciplinary approach. The twins' father is also affected with features of Currarino's syndrome but was diagnosed during family screening. Currarino's syndrome presenting with identical neonatal low intestinal obstruction in a non-identical set of twins is rare and interesting. Antenatal diagnosis of Currarino's syndrome is difficult and may prove to be a challenge even in the postnatal period. Sacral spine radiograph, contrast enema and MRI are diagnostic. Management requires high index of suspicion, low threshold for MRI and multidisciplinary staged approach.

    Sodium polystyrene sulfonate (Kayexalate) and calcium polystyrene sulfonate (CPS, Kalimate) are commonly used to reduce serum potassium. There were some published evidences of severe gastrointestinal complications from the administration of these agents such as colonic necrosis with or without perforation and acute obstruction. The authors reported a 52-year-old male patient being critically ill from severe soft tissue infection of the right leg and sepsis. Hyperkalemia had occurred due to renal insufficiency and required several doses of Kalimate to reduce the serum potassium level. Subsequently, the patient developed complete intestinal obstruction and an exploratory laparotomy was performed. The intra-operative findings were distended stomach and the small bowel contained a large amount of intraluminal affected Kalimate that was removed via gastrotomy and enterotomy. These findings suggested that the inspissated Kalimate could lead to significant obstruction of the gastrointestinal tract in some groups of patient.

    The aim of the present study was to investigate intestinal mucosal barrier dysfunction in a rat model of chronic obstructive pulmonary disease (COPD). Male Sprague Dawley rats (n=40) were evenly randomized into control and COPD groups and the COPD model was established by regulated exposure to cigarette smoke for 6 months. Histopathological changes of the lung and intestinal tissues were detected by hematoxylin and eosin staining. Expression of the tight junction proteins occludin and zona occludens-1 (ZO-1) in the intestinal tissues were analyzed by western blotting, serum diamine oxidase (DAO) activity was detected by spectrophotometry, the urinary lactulose to mannitol ratio (L/M) was evaluated by high performance liquid chromatography, and intestinal tissue secretion of tumor necrosis factor (TNF)-α, interferon (IFN)-γ and interleukin (IL)-8 were detected by ELISA. Lung histopathology revealed thinned alveolar walls, ruptured alveolar septa, enlarged and deformed alveoli, and the formation of bullae and emphysema due to alveolar fusion in the COPD group, while intestinal histopathology indicated clearly swollen intestines with darkened and gray mucosa, neutrophil infiltration of the intestinal mucosal and regional epithelial shedding. The occludin and ZO-1 expression levels were significantly lower in the COPD group compared with those in the corresponding control group (P<0.05), while the urinary L/M ratio was significantly higher (P<0.05). Furthermore, the serum DAO activity and secretion of TNF-α, IFN-γ and IL-8 in the intestinal tissues were significantly higher in the COPD group than in the control group (each P<0.05). Dysfunctional and structural changes were observed in the intestinal mucosal barrier in COPD model rats, which may be associated with the increased intestinal inflammatory responses. PMID:27588054

    An 11-year-old boy with irreversible intestinal failure secondary to chronic intestinal pseudo-obstruction (CIPO) and intestinal failure-associated liver disease (IFALD) underwent a combined en bloc reduced liver and small bowel transplantation. He was discharged home after 9 weeks on full oral intake without requiring intravenous nutritional or fluid supplementation. The first episode of mild acute rejection, which occurred 18 months after transplantation, was successfully treated with steroids. An episode of rotavirus gastroenteritis led to severe exfoliative rejection of the bowel graft, which was resistant to steroid and Infliximab treatment but responded to OKT3. There was associated Epstein-Barr virus viremia with no evidence of posttransplant lymphoproliferative disease. Another episode of moderate to severe acute liver rejection occurred 5 months later. At the same time, multiple biliary strictures were diagnosed and treated. Persistent clinical symptoms of abdominal pain and increased stomal output as well as atrophy of the ileal mucosa on several biopsies, suggested the possibility of chronic rejection (CR). A second combined whole liver and small bowel transplant was performed. The diagnosis of CR was confirmed on histology of the explanted graft. The postoperative course was severely complicated and 71 days after the retransplantation, the boy died because of respiratory failure and multiorgan failure. In summary, intestinal transplantation can be successfully performed in children with CIPO, giving them the opportunity to be free from total parenteral nutrition. As survival following intestinal transplantation continues to improve, the problem of CR has become increasingly important and the only treatment available is retransplantation, which is associated with poor outcomes.

    This report describes the fecalith-induced intestinal obstruction of a free-ranging red diamond rattlesnake (Crotalus ruber) and the snake's subsequent history following surgical removal of the fecalith. The captured snake exhibited an abnormally distended abdomen and an extremely hard mass, detected via palpation, near its vent. Coeliotomy yielded a 2.5-cm, 5-g fecalith from the large intestine. Microscopic dissection of the fecalith revealed no evidence of gastrointestinal parasitic worms. Subsequently, we implanted a radio-transmitter that allowed us to track the snake's movements for 7 months (until the radio signal vanished), indicating normal behaviour, complete recovery and good health apart from the obstruction. This observation suggests that fecalith development and intestinal obstruction represent potential risks of long-term faecal retention, an unusual physiological trait well documented among rattlesnakes and other stout, heavy-bodied terrestrial viperid snakes. Dehydration and decreased gut motility associated with brumation (≈hibernation) may predispose temperate snakes to fecalith formation. Regional drought and a small mammal diet with indigestible hairs might have also promoted fecalith formation in this specimen.

    Kidney transplantation is the treatment of choice for end-stage renal disease whereas indications for intestinal transplantation are currently restricted to patients with irreversible small bowel failure and severe complications of total parenteral nutrition (mostly shortage and infection of venous accesses, major electrolyte disturbances and liver failure). Enteric hyperoxaluria is secondary to certain intestinal diseases like intestinal resections, chronic inflammatory bowel disease and other malabsorption syndromes and can lead to end-stage renal disease requiring kidney transplantation. We report two patients suffering from renal failure due to enteric hyperoxaluria (secondary to extensive intestinal resection) in whom we elected to replace not only the kidney but also the intestine to prevent recurrence of hyperoxaluria in the transplanted kidney.

    Two cases are reported of chronic, partial afferent loop obstruction with resultant obstructive jaundice in recurrent gastric cancer. The diagnosis was made by characteristic clinical presentations, abdominal computed tomography, and cholescintigraphy. Percutaneous transhepatic duodenal drainage (PTDD) provided effective palliation for both afferent loop obstruction and biliary stasis. We conclude that cholescintigraphy is of value in making the diagnosis of partial afferent loop obstruction and in differentiating the cause of obstructive jaundice in such patients, and PTDD provides palliation for those patients in whom surgical intervention is not feasible.

The patient presented to the emergency department at the authors' institution with a 1-day history of projectile vomiting, lethargy, and dysconjugate gaze. Hydrocephalus was confirmed on head CT. During hospitalization, the symptoms resolved with a decrease in ventricular size. One week later, the patient again presented with similar symptoms, and MR images with 3D-constructive interference in steady state sequences revealed that a cyst was blocking the third ventricle. The patient subsequently underwent endoscopic fenestration of the cyst with resolution of hydrocephalus and symptoms. The authors present a unique description of the diagnosis of intermittent obstructive hydrocephalus caused by a third ventricular region choroid plexus cyst in an infant.

    Intestinal lymphangiectasia (IL) is a rare disease characterized by dilatation of intestinal lymphatics. It can be classified as primary or secondary according to the underlying etiology. The clinical presentations of IL are pitting edema, chylous ascites, pleural effusion, acute appendicitis, diarrhea, lymphocytopenia, malabsorption, and intestinal obstruction. The diagnosis is made by intestinal endoscopy and biopsies. Dietary modification is the mainstay in the management of IL with a variable response. Here we report 2 patients with IL in Bahrain who showed positive response to dietary modification. PMID:26837404

    We report on two patients with recurrent episodes of chronic intestinal pseudo-obstruction (CIPO). A 50-year-old woman with severe multiple sclerosis and an 84-year-old man with Parkinson's disease and dementia had multiple hospital admissions because of pain and distended abdomen. Radiographic and endoscopic findings showed massive dilation of the colon without any evidence of obstruction. Conservative management resolved symptoms only for a short period of time. As these patients were poor candidates for any surgical treatment we carried out percutaneous endoscopic colostomy by placing a 20-Fr tube in the cecum with the introducer method. The procedure led to durable symptom relief without complications. We present these two cases and give a review through the existing literature of the procedure in CIPO.

    Medical management of systemic sclerosis (SSc)-associated chronic intestinal pseudo- obstruction (CIPO) has often proved inadequate. Percutaneous endoscopic colostomy (PEC) has been proposed as a method of treatment, but it is associated with a relatively high incidence of serious complications. We report herein a very severe case of SSc-associated CIPO in which complications were successfully controlled by long tube placement via a gastrostomy. Transgastric long tube placement may offer a relatively safe alternative to PEC in treating severe SSc-associated CIPO.

    Ventriculoperitoneal (VP) shunt complications are common, but abdominal complications are rare. The objective of this report is to present 2 cases of intestinal obstruction due to a VP shunt and review the literature for data on this rare occurrence.A 4-month-old boy received surgical resection of a medulloblastoma and a VP shunt was inserted to manage progressive hydrocephalus. Two months later, he was admitted with intermittent vomiting, and plain abdominal radiography showed complete intestinal obstruction. Emergency laparotomy revealed an adhesive intestinal obstruction around the catheter, and approximately 5 cm of necrotic ileum was resected. His recovery was uneventful. In the second case, a 6-year-old boy was diagnosed with a primary nongerminomatous malignant germ cell tumor and a VP shunt was place to treat hydrocephalus. Two weeks after the first course of chemotherapy, he went into a coma; computed tomography demonstrated enlargement of the tumor and gross total resection was performed. Two weeks later, he developed abdominal distention; plain radiography showed intestinal obstruction and laparotomy revealed adhesive intestinal obstruction around the catheter with 15 cm of necrotic ileum. The necrotic bowel was resected. Unfortunately, the patient developed sepsis and despite treatment remained in a vegetative state.Medline, Central, Embase, and Google Scholar databases were searched up to May 9, 2014, using the terms VP shunt, shunting, and/or intestinal obstruction. Only cases involving children or adolescents were included. Eleven reports involving patients with abdominal complications resulting from a VP shunt for hydrocephalus were identified. The dates of the reports spanned from 1971 to 2014. Volvulus was the most common cause of VP shunt-related obstruction, and mechanical obstruction due to twisting of the catheter the second most common. Only 1 case in the literature review was related to intestinal adhesions. Treatment in most cases was

    The purpose of this study was to determine the spectrum of findings and the frequency of apparent distal colonic obstruction on abdominal radiographs in women with obstructive symptoms following Caesarean section. A search of radiology files yielded 21 patients who had abdominal radiographs because of obstructive symptoms during the early post-operative period. The radiographs were reviewed retrospectively to characterize the bowel gas patterns in these patients. Medical records were also reviewed to determine the treatment and patient course. Abdominal radiographs showed findings suggestive of distal colonic obstruction in 15 patients (71%), small bowel obstruction in 2 (10%), adynamic ileus in 3 (14%) and a normal bowel gas pattern in 1 (5%). In all 15 patients with apparent distal colonic obstruction, there was minimal or no gas in the rectosigmoid, with an associated pelvic mass representing the enlarged post-partum uterus, which compressed the rectosigmoid and prevented it from filling with gas. All 21 patients had rapid clinical or radiographic improvement on conservative management, indicating a transient post-operative ileus. Radiologists should be aware of the limitations of abdominal plain radiographs following Caesarean section so that a post-operative ileus is not mistaken for a distal colonic obstruction and conservative measures can be undertaken to decompress the bowel until the ileus resolves.

    Percutaneous endoscopic colostomy (PEC), using the classic pull-through technique in the ascending or the descending colon, has been proven useful to treat chronic intestinal pseudo-obstruction. We report the case of a high-surgical risk 70-year-old male with refractory chronic intestinal pseudo-obstruction, in whom the ascending colon could not be reached due to tortuous left dolichocolon. Endoscopic-assisted colopexy and push colostomy in the proximal transverse colon was decided accordingly. Colopexy was performed under direct endoscopic vision in the proximal transverse colon using 3 preloaded T-fasteners surrounding the intended stoma site. The stoma tract was created with an introducer needle, allowing the advance of the 24 Fr 4-sleeve dilator over a guidewire. Afterwards, the dilator was removed and the peel-away sheath was left in place. Over the guidewire, a 20-Fr gastrostomy tube was advanced into the colon lumen through the covering, which was finally removed. The patient recovered uneventfully, despite postprocedure pneumoperitoneum, which was related to the technique. He died a month later due to unrelated comorbidities, without further abdominal complaints after discharge. This is the first report of PEC both using a push technique, and the first report in a different location than the ascending or the descending colon. We believe this novel push technique may be feasible for PEC, avoiding the need of reinsertion in patients with difficult colonoscopy.

    Introduction. Gallstone ileus (GSI) of the colon is an extremely rare entity with potentially serious complications including perforation. Case Presentation. An 88-year-old man presented to the emergency department with abdominal pain and distension. Clinical exam revealed signs of peritonism. Computed tomography (CT) revealed GSI of the transverse colon with a closed-loop large bowel obstruction (LBO) and caecal perforation. The patient underwent emergency laparotomy. A right hemicolectomy was performed, the gallstone was removed, and a primary bowel anastomosis was undertaken. A Foley catheter was sutured into the residual gallbladder bed to create a controlled biliary fistula. The patient recovered well postoperatively with no complications. He was discharged home with the Foley catheter in situ. Discussion. Gallstone ileus is a difficult diagnosis both clinically and radiologically with only 50% of cases being diagnosed preoperatively. Most commonly it is associated with impaction at the ileocaecal valve and small bowel obstruction. Gallstone ileus should also be considered as a rare but potential cause of LBO. This is the first reported case of caecal perforation secondary to gallstone ileus of the transverse colon. Successful operative management consisted of a one-stage procedure with right hemicolectomy and formation of a controlled biliary fistula.

    Intestinal neuronal dysplasia type B (IND B) is an infrequent disease due to hyperplasia of the parasympathetic submucous plexus which causes alteration of intestinal motility, giving rise to symptoms of constipation and subocclusive manifestations. The disease is difficult to diagnose. It requires high clinical suspicion and should include differential diagnosis of patients with repeated subocclusive manifestations in order to make an early and correct diagnosis and avoid complications derived from unnecessary surgery that worsens the prognosis. We present the case of a 33-year-old Moroccan male who was admitted to our hospital on 2 occasions in 11 months, requiring total parenteral nutrition (TPN) for five months. The immunohistochemical analysis of the ileostomy and colostomy stoma led to a diagnosis of IND B. Eighteen months later, the patients is leading a normal life and has recovered the 25 kilos lost following the dietary indications and with the enzymatic supplements.

    Probiotic is a preparation containing microorganisms that confers beneficial effect to the host. This work assessed whether oral treatment with viable or heat-killed yeast Saccharomyces cerevisiae strain UFMG 905 prevents bacterial translocation (BT), intestinal barrier integrity, and stimulates the immunity, in a murine intestinal obstruction (IO) model. Four groups of mice were used: mice undergoing only laparotomy (CTL), undergoing intestinal obstruction (IO) and undergoing intestinal obstruction after previous treatment with viable or heat-killed yeast. BT, determined as uptake of (99m)Tc-E. coli in blood, mesenteric lymph nodes, liver, spleen and lungs, was significantly higher in IO group than in CTL group. Treatments with both yeasts reduced BT in blood and all organs investigated. The treatment with both yeasts also reduced intestinal permeability as determined by blood uptake of (99m)Tc-DTPA. Immunological data demonstrated that both treatments were able to significantly increase IL-10 levels, but only viable yeast had the same effect on sIgA levels. Intestinal lesions were more severe in IO group when compared to CTL and yeasts groups. Concluding, both viable and heat-killed cells of yeast prevent BT, probably by immunomodulation and by maintaining gut barrier integrity. Only the stimulation of IgA production seems to depend on the yeast viability.

    A 26-year-old patient was diagnosed as having chronic intestinal pseudo-obstruction with manometric and histopathologic features suggestive of an intestinal myopathy. Histology was characterized by smooth muscle degeneration without inflammatory or immune cells. The severe gut dysfunction required full parenteral nutritional support. After a few months, the patient developed symptomatic tachy-brady arrhythmia episodes with syncopes. A thorough diagnostic work-up led to a diagnosis of sick sinus syndrome, which was managed by pacemaker implantation and administration of β-blockers. This led to a partial improvement in tachy-brady arrhythmia episodes. Nonetheless, the patient continued to experience sustained supraventricular tachyarrhythmia runs, poorly responsive to increasing β-blocker doses. To investigate the origin of the cardiologic impairment, the patient was tested for anticonductive tissue autoantibodies, which were positive, thus supporting a possible autoimmune origin of the dysrhythmia. Other autoantibodies were negative. On the basis of these findings, the patient was treated with high-dose steroids, which were then tapered. The patient responded to the steroid treatment and did not experience further episodes of syncope and tachyarrhythmias. The severe gut dysfunction remained unchanged. This case highlights an association between severe gut dysfunction and cardiac conductive tissue abnormalities, with autoantibodies to conductive tissue possibly causing the dysrhythmia. The severe gut and heart (likely autoimmune-mediated) dysfunction presented in this case provides a basis to further assess a link between intestinal and cardiac abnormal rhythmicity.

    A 7-year-old male trotter horse with a history of recurrent colic displayed clinical findings consistent with chronic intestinal pseudo-obstruction (CIP). At laparotomy, an impaction of the descending colon associated with marked atrophy of the right dorsal colon was found. The horse was humanely destroyed and tissues collected at necropsy examination revealed diffuse enteric ganglionitis comprising an infiltrate of CD3(+) T lymphocytes and plasma cells. At all levels of the intestinal tract the number of myenteric ganglia and of normal ganglion cells was decreased significantly. There were chromatolytic or necrotic neurons and the amount of connective tissue surrounding ganglia was increased. Immunohistochemical studies demonstrated slightly reduced expression of neuron-specific enolase and a moderate increase in expression of S100 and glial fibrillary acidic protein in a sample of right dorsal colon taken during the necropsy examination compared with a biopsy sample taken from the same location. Immunolabelling and semi-nested polymerase chain reaction for equine herpesvirus (EHV)-1 performed on the gut were positive, supporting an aetiological relationship between EHV-1 infection and the enteric ganglionitis.

    The absence of bile in the gut lumen induces mucosal injury and promotes bacterial translocation (BT). Prostaglandin E (PGE) has a protective effect on the mucosal layer of the alimentary tract. We hypothesize that PGE1 may prevent BT by its beneficial action on the mucosa of the small bowel. Thirty Wistar albino rats were divided equally into 3 groups; Group 1 (control) underwent sham laparotomy, group 2 obstructive jaundice (OJ) and group 3 (OJ + PGE1) underwent common bile duct (CBD) ligation and transection. Groups 1 and 2 received; 1 mL normal saline and group 3 received 40 mg of the PGE1 analogue misoprostol dissolved in 1 mL normal saline administered by orogastric tube once daily. After 7 days, laparotomy and collection of samples for laboratory analyses were performed, including bacteriological analysis of intestine, mesenteric lymph nodes (MLNs), and blood, and histopathologic examination of intestinal mucosa to determine mucosal thickness and structural damage. Serum bilirubin and alkaline phosphatase levels confirmed OJ in all animals with CBD transection. The mucosal damage score was significantly reduced in jaundiced animals receiving PGE1 compared to jaundiced controls (2.15 +/- 0.74 vs 5.3 +/- 0.59; p < .00001) and mucosal thickness was greater (607 +/- 59.1 microm vs. 393 +/- 40.3 microm; p < .00001). The incidence of BT to MLNs decreased from 90% to 30% (p < .02) when jaundiced rats received PGE1. PGE1 treatment reduced the detection rate of viable enteric bacteria in the blood from 60% to 10% (p < .057). We conclude that administration of PGE1 provides protection against OJ-induced atrophy and damage of intestinal mucosa, and thereby prevents translocation of enteric bacteria to underlying tissues.

    Chronic intestinal pseudo-obstruction (CIPO) syndromes are heterogeneous gastrointestinal disorders, caused by either neuropathy or myopathy, resulting in compromised peristalsis and intestinal obstruction. CIPO can have a profound impact on quality of life, leading the most severely affected individuals to life-long parenteral nutrition and urinary catheterization. To search for disease causing gene(s), we performed the whole exome sequencing (WES) in both eight sporadic and two familial cases, followed by targeted sequencing in additional CIPO patients. After identifying a heterozygous missense variant in the ACTG2 gene in one of 10 patients undergone WES, targeted Sanger sequencing of this gene allowed to detect heterozygous missense variants in 9 of 23 further patients with either megacystis-microcolon-intestinal hypoperistalsis syndrome or intestinal pseudo-obstruction. Variants thus identified, one of which still unreported, affect highly conserved regions of the ACTG2 gene that encodes a protein crucial for correct enteric muscle contraction. These findings provided evidence for a correlation between the clinical phenotype and genotype at the ACTG2 locus, a first step to improve the diagnosis and prognosis of these severe conditions.

    An adult Bengal cat (Felis catus × Prionailurus bengalensis) with a prolonged history of partial anorexia, regurgitation, and weight loss and a clinical, radiographic, and ultrasonographic diagnosis of persistent megaesophagus and gastrointestinal ileus was submitted for necropsy. The intestinal tract was diffusely distended by gas and fluid with appreciable loss of muscle tone and an absence of luminal obstruction, consistent with the clinical history of chronic intestinal pseudo-obstruction. Histologically, the autonomic nervous system was intact, but the smooth muscle within the gastrointestinal wall exhibited a marked basophilia that was most pronounced in the jejunum. Immunohistochemistry for neurofilament, synaptophysin, CD117, and desmin demonstrated that the number of myenteric ganglia, number of interstitial cells, and leiomyocyte desmin content were similar when compared with the unaffected age- and species-matched control. Immunohistochemistry for smooth muscle α-actin demonstrated a striking loss of immunoreactivity, predominantly in the circular layer of the jejunum, that corresponded with the tinctorial change in leiomyocytes. Transmission electron microscopy revealed loss of myofibrils, loss of organelle polarity, and significantly larger central mitochondria (megamitochondria) in affected leiomyocytes, as well as nonspecific degenerative changes. Although the presence of a primary leiomyopathy and a causal relationship could not be confirmed in this case, leiomyopathies are considered a cause of chronic intestinal pseudo-obstruction in human medicine, and loss of smooth muscle α-actin immunoreactivity is one recognized marker for intestinal dysmotility.

    Intestine and intestine-liver transplant plays an important role in the treatment of intestinal failure, despite decreased morbidity associated with parenteral nutrition. In 2014, 210 new patients were added to the intestine transplant waiting list. Among prevalent patients on the list at the end of 2014, 65% were waiting for an intestine transplant and 35% were waiting for an intestine-liver transplant. The pretransplant mortality rate decreased dramatically over time for all age groups. Pretransplant mortality was highest for adult candidates, at 22.1 per 100 waitlist years compared with less than 3 per 100 waitlist years for pediatric candidates, and notably higher for candidates for intestine-liver transplant than for candidates for intestine transplant without a liver. Numbers of intestine transplants without a liver increased from a low of 51 in 2013 to 67 in 2014. Intestine-liver transplants increased from a low of 44 in 2012 to 72 in 2014. Short-gut syndrome (congenital and other) was the main cause of disease leading to both intestine and intestine-liver transplant. Graft survival improved over the past decade. Patient survival was lowest for adult intestine-liver recipients and highest for pediatric intestine recipients.

    We report a rare, but serious, complication of a malpositioned umbilical venous catheter in a term male infant who developed laceration, hematoma, and necrosis of liver, ascites, and left-sided obstructive uropathy secondary to extravasation of total parenteral nutrition. Abdominal paracentesis confirmed the presence of parenteral nutrition in the peritoneal cavity. Although, the umbilical venous catheterization is a common intravenous access used in neonatal intensive care units, judicious continued monitoring of its use should be practiced to avoid serious complications.

    Background and Objectives: Small-bowel obstruction (SBO) is a common surgical emergency that occurs in 9% of patients after abdominal surgery. Up to 73% are caused by peritoneal adhesions. The primary purpose of this study was to compare the rate of SBOs between patients who underwent laparoscopic (LPS) and those who had open (OPS) colorectal surgery. The secondary reasons were to evaluate the rate of adhesive SBO in a cohort of patients who underwent a range of colorectal resections and to assess risk factors for the development of SBO. Method: This was a retrospective observational cohort study. Data were analyzed from a prospectively collected database and cross checked with operating theater records and hospital patient management systems. Results: During the study period, 707 patients underwent colorectal resection, 350 of whom (49.5%) were male. Median follow-up was 48.3 months. Of the patients included, 178 (25.2%) underwent LPS, whereas 529 (74.8%) had OPS. SBO occurred in 72 patients (10.2%): 20 (11.2%) in the LPS group and 52 (9.8%) in the OPS group [P = .16; hazards ratio (HR) 1.4 95% CI 0.82–2.48] within the study period. Conversion to an open procedure was associated with increased risk of SBO (P = .039; HR 2.82; 95% CI 0.78–8.51). Stoma formation was an independent risk factor for development of SBO (P = .049; HR, 0.63; 95% CI 0.39–1.03). The presence of an incisional hernia in the OPS group was associated with SBO (P = .0003; HR, 2.85; 95% CI 1.44–5.283). There was no difference in SBO between different types of procedures: right colon, left colon, and rectal surgery. Patients who developed early small-bowel obstruction (ESBO) were more often treated surgically compared to late SBO (P = .0001). Conclusion: The use of laparoscopy does not influence the rate of SBO, but conversion from laparoscopic to open surgery is associated with an increased risk of SBO. Stoma formation is associated with a 2-fold increase in SBO. Development of ESBO is

    Dai-kenchu-to (DKT), a traditional Japanese herbal medicine (Kampo medicine), composed of zanthoxylum fruit, ginseng root, dried ginger rhizome and malt sugar, is clinically effective for postoperative ileus and chronic constipation. MMIHS and CIIP are severe motility disorder associated with high morbidity. The aim of this study was to evaluate the effect of DKT on functional intestinal obstruction. DKT was clinically effective for gastrointestinal motility in a case with MMIHS, but not effective in one with CIIP. MMIHS and CIIP are speculated to have different pathogenesis regarding gastrointestinal pseudo-obstruction based upon the effect of this drug.

    Bowel obstruction due to bezoars (compaction of ingested material within the gastrointestinal tract) is a rare, but well documented occurrence. In this paper, we present two cases of potato-induced small bowel obstruction. Both patients were approximately 50 years old and had cerebral palsy and learning disabilities, respectively. They presented with abdominal pain and bilious vomiting, with no medical or surgical history. Diagnosis of small bowel obstruction was confirmed by CT prior to taking the patients to the operating theatre, where whole potatoes were found to be obstructing each patient's bowel lumen. Both patients underwent laparotomy with enterotomy and removal of the potato. They both made a good recovery. Through a literature review of bezoar-induced bowel obstruction, these cases highlight important diagnostic and management principles.

    A 37-year-old woman who had previously been diagnosed with idiopathic chronic intestinal pseudo-obstruction (CIPO) at another hospital was admitted to our institution with severe abdominal pain. She had a history of several abdominal surgeries to treat ileus at the previous hospital, and contrast-enhanced computed tomography on admission revealed subileus without any apparent causes of obstruction. Total parenteral nutrition, a gastrointestinal prokinetic agent, and opiates reduced persistent pain;however, breakthrough pain continued. A neurologist at our hospital suggested autoimmune autonomic ganglionopathy (AAG) as a potential cause of CIPO. The patient was diagnosed with suspected AAG on the basis of seropositive results for anti-ganglionic acetylcholine receptor antibody. Intravenous immunoglobulin administration and plasma exchange were performed in combination with immunosuppressive drugs;however, her symptoms barely improved. Although percutaneous endoscopic gastrostomy and enterostomy were subsequently performed to reduce internal intestinal pressure, her pain relief was insufficient.

    A 55-year-old woman with a history of bowel dysmotility presented with abdominal distension and peritonitis. Family history included premature deaths with intestinal symptomatology, suggesting autosomal dominant inheritance. Computed tomography showed a distended small bowel. Symptoms were alleviated by enterocutaneous stomas. Initial ileal biopsy suggested neuropathy; however, exome sequencing revealed an Arg148Ser mutation in the enteric smooth muscle actin gamma 2 (ACTG2) gene. Histological reassessment showed abnormal muscularis propria and smooth muscle actin, with the same findings in sibling, confirming familial visceral myopathy. Thus, noninvasive genomic analysis can provide early and specific diagnosis of familial visceral myopathy, which may help to avoid inappropriate surgery.

    A 24-year-old female patient presented to our community emergency department (ED) for abdominal pain that had progressively worsened over the last 28 hours. Of note, 1 month prior to her presentation, the patient had a colostomy due to a rectal abscess and required stoma revision 5 days prior to her visit to our ED. The patient's pain was refractory to opiate analgesia in our ED, but experienced significant relief after an intravenous lidocaine infusion. Computer tomography of the abdomen and pelvis ultimately revealed a large bowel obstruction just proximal to the colostomy site. Historically, options for ED management of severe pain have been limited beyond narcotic analgesia. For patients whom are refractory to opiates in the ED, or for whom opiates are contraindicated, lidocaine infusions have shown promise for a variety of both acute and chronic painful conditions.

    Only few case studies address pseudo-obstruction, a disorder - which often frustrates clinicians and patients due to an unclear diagnosis and limited therapeutic options. Thus, the aim of this paper is to investigate a relevant case concerning a patient presenting with symptoms of acquired chronic intestinal pseudo-obstruction (CIPO). After one year of extensive diagnostic tests and unsuccessful treatment with prokinetics, the patient underwent a subtotal ileocolectomy. The histology of the intestinal specimen revealed continuous atrophy and fibrosis mainly within the circular, inner muscle layer of muscularis propria of the ileum and colon. Even though serum markers were lacking, a subsequent skin biopsy showed signs of scleroderma supporting an initial diagnosis of intestinal involvement in systemic sclerosis. Despite treatment with steroids and methotrexate, the increasingly emaciated patient died. In conclusion, there is a bias against the publishing of pseudo-obstruction studies, in particular, due to the obscure underlying causes. To raise awareness of this problem, we call for clinicians to systematically generate comprehensive data about patients presenting these symptoms.

    Effective therapies are limited for patients with parenteral nutrition-dependent short bowel syndrome. We previously showed that intestinal expression of the transcriptional coregulator tetradecanoyl phorbol acetate-induced sequence 7 (tis7) is markedly increased during the adaptive response following massive small bowel resection and tis7 plays a role in normal gut lipid metabolism. Here, we further explore the functional implications of tis7 deletion in intestinal lipid metabolism and the adaptive response following small bowel resection. Intestinal tis7 transgenic (tis7(tg)), tis7(-/-), and wild-type (WT) littermates were subjected to 50% small bowel resection. Mice were fed a control or a high-saturated-fat (42% energy) diet for 21 days. Survival, body weight recovery, lipid absorption, mucosal lipid analysis, and the morphometric adaptive response were analyzed. Quantitative real-time PCR was performed to identify tis7 downstream gene targets. Postresection survival was markedly reduced in high-fat, but not control, diet-fed tis7(-/-) mice. Decreased survival was associated with anastomotic inflammation and intestinal obstruction postresection. High-fat, but not control, diet-fed tis7(-/-) mice had increased intestinal IL-6 expression. Intestinal lipid trafficking was altered in tis7(-/-) compared with WT mice postresection. In contrast, high-fat diet-fed tis7(tg) mice had improved survival postresection compared with WT littermates. High-fat diet feeding in the setting of tis7 deletion resulted in postresection anastomotic inflammation and small bowel obstruction. Tolerance of a calorie-rich, high-fat diet postresection may require tis7 and its target genes. The presence of luminal fat in the setting of tis7 deletion promotes an intestinal inflammatory response postresection.

    Malignant biliary tract obstruction (MBTO) due to either primary biliary tract cancer or metastasis to the porta hepatis is a common clinical problem. The most common metastatic tumors causing MBTO in order of frequency are gastric, colon, breast, and lung cancers. Radiographic diagnostic procedures should proceed in a cost-effective sequence from ultrasonography, computerized tomography (CT), percutaneous transhepatic cholangiography (PTHC), and endoscopic retrograde pancreatography with the goal of establishing the site of the biliary tract obstruction. The identification of the site of obstruction could be established by ultrasound 70% to 80%, CT scan 80% to 90%, PTHC 100%, and endoscopic retrograde cholangiography (ERCP) 85%. Therapeutic intervention by radiographic decompression (PTHC or endoscopic prosthesis), surgical bypass, or radiation therapy with or without chemotherapy may be selectively used based on (1) the site of obstruction; (2) the type of primary tumor; and (3) the presence of specific symptoms related to the obstruction. ("Prophylactic" biliary tract decompression to prevent ascending cholangitis is not supported by the literature in that the frequency of sepsis in the face of malignant obstruction is small (in contrast to sepsis associated with stone disease). Furthermore, PTHC with drainage as a long-term procedure is associated with a substantial frequency of sepsis and is unnecessary and possibly problematic as a preoperative procedure simply to reduce the bilirubin level. The use of radiation therapy in conjunction with chemotherapy for patients not deemed suitable for a surgical bypass because of the presence of proximal obstruction is an important alternative to PTHC.

    Patients presenting with symptoms caused by gallstones are common on a surgical take. Understanding the different ways in which this common condition can present is important to enable the correct diagnosis and thus management plan. The immediate management of gallstones depends on the presenting features and can range from analgesia to surgical intervention. Obstructive cases require intervention, either by ERCP or surgery; the non-obstructive cases are usually left to settle before an elective operation at a later date. In surgery, the presence of a clinical sign where it 'should not be' can be a sign of another underlying pathology and this is the embodiment of surgery-to assimilate seemingly disparate pieces of information and act in a way to treat the cause. This case study highlights a rare presentation of one disease state, in vomiting of gallstones, that raised the diagnosis of another pathology, a small bowel obstruction.

    Maternally inherited diabetes and deafness (MIDD) has been related to an A to G transition in the mitochondrial tRNA Leu (UUR) gene at the base pair 3243. This subtype of diabetes is characterized by maternal transmission, young age at onset and bilateral hearing impairment. Besides diabetes and deafness, the main diagnostic features, a wide range of multisystemic symptoms may be associated with the A3243G mutation. Organs that are most metabolically active, such as muscles, myocardium, retina, cochlea, kidney and brain are frequently affected. Gastrointestinal tract symptoms are also common in patients with mitochondrial disease and constipation and diarrhea are the most frequent manifestations. However, there are few prior reports of intestinal pseudo obstruction in MIDD patients. Here we report the case of a patient with MIDD associated with the mtDNA A3243G mutation who developed chronic intestinal pseudo obstruction, and the introduction of Coenzyme Q10 as adjunctive therapy led to a solution of the pseudo obstruction.

    OBJECT Endoscopic third ventriculostomy (ETV) is the treatment of choice for obstructive hydrocephalus; however, the success of ETV in patients who have previously undergone shunt placement remains unclear. The present study analyzed 103 adult patients with aqueductal stenosis who underwent ETV for obstructive hydrocephalus and evaluated the effect of previous shunt placement on post-ETV outcomes. METHODS This study was a retrospective review of 151 consecutive patients who were treated between 2007 and 2013 with ETV for hydrocephalus. One hundred three (68.2%) patients with aqueductal stenosis causing obstructive hydrocephalus were included in the analysis. Postoperative ETV patency and aqueductal and cisternal flow were assessed by high-resolution, gradient-echo MRI. Post-ETV Mini-Mental State Examination, Timed Up and Go, and Tinetti scores were compared with preoperative values. Univariate and multivariate analyses were performed comparing the post-ETV outcomes in patients who underwent a primary (no previous shunt) ETV (n = 64) versus secondary (previous shunt) ETV (n = 39). RESULTS The majority of patients showed significant improvement in symptoms after ETV; however, no significant differences were seen in any of the quantitative tests performed during follow-up. Symptom recurrence occurred in 29 (28.2%) patients after ETV, after a median of 3.0 (interquartile range 0.8-8.0) months post-ETV failure. Twenty-seven (26.2%) patients required surgical revision after their initial ETV. Patients who received a secondary ETV had higher rates of symptom recurrence (p = 0.003) and surgical revision (p = 0.003), particularly in regard to additional shunt placement/revision post-ETV (p = 0.005). These differences remained significant after multivariate analysis for both symptom recurrence (p = 0.030) and surgical revision (p = 0.043). CONCLUSIONS Patients with obstructive hydrocephalus due to aqueductal stenosis exhibit symptomatic improvement after ETV, with a

    Femoral hernias account for 2% to 4% of groin hernias, are more common in women, and are more appropriate to present with strangulation and require emergency surgery.This condition may lead to symptoms of bowel obstruction or strangulation and possible bowel resection-anastomosis. To the best of our knowledge, there is few reports of strangulated femoral hernia.We herein present an 82-year-old lady who presented with a 5-day history of abdominal pain, nausea and vomiting. On examination, the patient had a generalized tenderness and distention. The working diagnosis at this time was a bowel obstruction. A computed tomography scan revealed the hernia occurring medial to the femoral vessels and below the inguinal ligament .Laparotomy was performed and patient was treated successfully with surgical therapy.Herniawas repaired and a small bowel resection was performed with end to end anastomosis. The postoperative course was uneventful, and the patient was doing well at a 12-month follow-up visit. Obstructing femoral hernia of the small bowel is rare and the physician should suspect femoral hernia as a bowel obstruction cause. PMID:27162928

A life-threatening complication of laryngeal sarcoidosis is upper airway obstruction. In this report we describe our experience in the acute and chronic care of a patient who required an emergent tracheostomy, with the aim to provide further insight into this difficult to manage disease. Case Report: A 37-year-old African American female with a 10-year history of stage 1 sarcoidosis presented with severe dyspnea. Laryngeal sarcoidosis was diagnosed three years previously, and she remained stable on low-dose prednisone until six months prior to admission, at which time she self-discontinued her prednisone for the homeopathic treatment Nopalea cactus juice. Her physical examination was concerning for impending respiratory failure as she presented with inspiratory stridor and hoarseness. Laryngoscopy showed a retroflexed epiglottis obstructing the glottis with edematous arytenoids and aryepiglottic folds. Otolaryngology performed an emergent tracheostomy to secure her airway and obtained epiglottic biopsies, which were consistent with sarcoidosis. She was eventually discharged home on prednisone 60 mg daily. Following months of corticosteroids, a laryngoscopy showed the epiglottis continuing to obstruct the glottis. The addition of methotrexate to a tapered dosage of prednisone 10 mg daily was unsuccessful, and she remains on prednisone 20 mg daily for disease control. Conclusions: Laryngeal sarcoidosis, a rare extrapulmonary manifestation of sarcoidosis, uncommonly presents as the life-threatening complication of complete upper airway obstruction.

    The objective of this study was to analyze three ureteral stenting techniques in patients with malignant ureteral obstructions, considering the indications, techniques, procedural costs, and complications. In the period between June 2003 and June 2006, 45 patients with bilateral malignant ureteral obstructions were evaluated (24 males, 21 females; average age, 68.3; range, 42-87). All of the patients were treated with ureteral stenting: 30 (mild strictures) with direct stenting (insertion of the stent without predilation), 30 (moderate/severe strictures) with primary stenting (insertion of the stent after predilation in a one-stage procedure), and 30 (mild/moderate/severe strictures with infection) with secondary stenting (insertion of the stent after predilation and 2-3 days after nephrostomy). The incidence of complications and procedural costs were compared by a statistical analysis. The primary technical success rate was 98.89%. We did not observe any major complications. The minor complication rate was 11.1%. The incidence of complications for the various techniques was not statistically significantly. The statistical analysis of costs demonstrated that the average cost of secondary stenting ( Euro 637; SD, Euro 115) was significantly higher than that of procedures which involved direct or primary stenting ( Euro 560; SD, Euro 108). We conclude that one-step stenting (direct or primary) is a valid option to secondary stenting in correctly selected patients, owing to the fact that when the procedure is performed by expert interventional radiologists there are high technical success rates, low complication rates, and a reduction in costs.

    Dynamic left ventricular outflow tract obstruction (DLVOTO) is a common condition in cats and humans. In this case report, a dog is described with DLVOTO secondary to severe intra-abdominal hemorrhage caused by a hemangiosarcoma. The dog was a 9-year-old, 35.7-kg, spayed female German Shepard dog that presented with a history of tachypnea and collapse. A Levine II/VI systolic murmur was present at the heart base. Abdominal ultrasonography revealed a splenic mass and a large amount of ascites. Echocardiography showed a reduced left ventricular diameter and an increased aortic velocity caused by systolic anterior motion (SAM) of the mitral valve apparatus. The heart murmur and the SAM were resolved after treatment including a splenectomy and a blood transfusion. PMID:25924797

    Peptic ulcers are an extremely common condition, usually occurring in the stomach and proximal duodenum. However, cases of peptic ulcers accompanied with multiple complications are extremely rare and hard to treat. The present case reinforces the requirement for the early recognition and correct treatment of peptic ulcers accompanied with multiple complications. A 67-year-old man presented with recurrent abdominal pain, fever and melena. The laboratory results showed anemia (hemoglobin 62 g/l) and hypoproteinemia (23 g/l). Abdominal imaging examinations revealed stones in the gallbladder and right liver, with air in the dilated intrahepatic and extrahepatic bile ducts. Endoscopic retrograde cholangiopancreatography failed due to a deformed pylorus. The patient was finally diagnosed with peptic ulcers accompanied with gastrointestinal (GI) bleeding, pylorus obstruction and cholangitis secondary to a choledochoduodenal fistula during an emergency pancreatoduodenectomy, which was performed due to a massive hemorrhage of the GI tract. The patient recovered well after the surgery. PMID:26870237

    This report describes the case of an 11-year-old castrated male Shih Tzu who developed chylothorax three years following implantation of a transvenous pacemaker. Imaging demonstrated one definitive obstruction in the cranial vena cava and 3 additional suspected filling abnormalities within both external jugular veins, brachiocephalic veins and cranial vena cava. A thrombus was visualized in the cranial vena cava via transesophageal echocardiography. Thoracic duct ligation and cisterna chyli ablation were performed, with a resultant change in the nature of the fluid from chylous to a modified transudate. Repeat angiography and computed tomography three months later demonstrated a stenosis within the cranial vena cava. Balloon angioplasty was attempted, however it was unsuccessful in decreasing pleural effusion. Palliative thoracocentesis was continued until the patient developed a lung lobe torsion, at which time euthanasia was elected. Necropsy confirmed cranial vena caval syndrome secondary to transvenous pacemaker implantation induced fibrous proliferation within the vessel lumen.

    Introduction Cardiac inflammatory myofibroblastic tumor is a rare tumor that can cause potentially fatal outcomes. Case Presentation We describe a case where the tumor originated on the mitral valve and extended through the left ventricular outflow tract and aortic valve and into the left main artery obstructing it. Due to the hemodynamic instability of the patient, we proceeded for cardiac catheterization with the intention to aspirate the mass but were forced to do percutaneous intervention to stabilize the patient and bridge him to surgery. Conclusions The patient underwent surgery several days later with complete resection of the tumor and coronary stent retrieval but his left ventricular ejection fraction remained poor after several months and he was referred for cardiac transplantation.

    We describe the case of an 81-year-old woman with large bowel-obstruction caused by an impacted gallstone. An 81-year-old, Caucasian, fully independent woman without significant comorbidities presented with absolute constipation, faecal vomiting and abdominal pain. Abdominal radiography revealed dilated small bowel, and a subsequent contrast CT demonstrated a 2.5 cm gallstone in the sigmoid colon. This is believed to have entered the transverse colon via a cholecyst-colonic fistula, and then migrated to a section of sigmoid colon affected by diverticular disease, where it became impacted. Two sigmoidoscopic removals were attempted but were unsuccessful as the gallstone's size prevented removal with an endoscopic basket. A laparotomy was performed and the stone extracted via a sigmoid enterotomy. No covering stoma was formed, and following 48 h on intensive trauma unit and a short ward-based stay for rehabilitation, the patient was discharged home and is currently doing well.

    Background. Residual vein obstruction (RVO), the persistence of venous thrombosis with time and often after anticoagulation, may indicate a systemic prothrombotic condition. Prior studies have shown varying efficacy in using RVO as a risk factor for future venous thromboembolic (VTE) recurrence. Methods. To assess whether positive RVO imaging predicts recurrent VTE events, we performed a meta-analysis on studies in which patients with documented VTEs, anticoagulated for a minimum of 4 weeks, had repeat sonography to assess RVO and were subsequently followed for recurrent events. Results. Thirteen studies met inclusion criteria: 3531 patient VTE events with 3474 evaluable results were analyzed. The presence of RVO was associated with recurrence in all VTE (OR 1.93; 95% CI: 1.29, 2.89) and secondary VTE (OR 2.78; 95% CI: 1.41, 5.5) but not for primary VTE (OR 1.35; 95% CI: 0.87, 2.08). When cancer patients were eliminated from the secondary VTE group, there was no longer a significant association of RVO with VTE recurrence (OR 1.73; 95% CI: 0.81, 3.67) while in the subset of cancer patients, presence of RVO was associated with an increase in VTE recurrence risk (OR 5.14; 95% CI: 1.59, 16.65, P < 0.006). Conclusions. We conclude that the presence of RVO is associated with recurrence in secondary VTE but not in primary VTE and that association may be driven by the subset with cancer.

    CASE DESCRIPTION A 13-year-old female green iguana (Iguana iguana) was examined because of a 6-day history of vomiting, anorexia, and lethargy and a 4-day history of decreased fecal and urate output. CLINICAL FINDINGS Physical examination revealed a distended abdomen, signs of depression, pallor, tachycardia, harsh lung sounds, and vomiting. Abdominal radiographs revealed gas distention of the stomach and small intestine with fluid lines evident on the lateral view. Plasma biochemical analysis indicated hypochloremic metabolic alkalosis, hyperglycemia, and hyperuricemia. TREATMENT AND OUTCOME Exploratory laparotomy confirmed a diagnosis of small intestinal entrapment and 170° volvulus involving approximately 80% (20 to 30 cm) of the small intestine. The portion of the small intestine extending from the middle portion of the duodenum to the caudal extent of the ileum was resected, and end-to-end anastomosis of the remaining small intestine was performed. The iguana recovered without apparent complications and was reportedly doing well 1 year after surgery. CLINICAL RELEVANCE Findings suggested that iguanas, as hindgut fermenters, may tolerate > 70% resection of the small intestine with a good outcome and no clinical evidence of residual gastrointestinal dysfunction.

    An 8-year-old girl with chronic idiopathic intestinal pseudo-obstruction (CIIP), who is the first case of CIIP in Japan, has been receiving total parenteral nutrition (TPN) for more than 6 years. During this time, she experienced deficiencies of copper, zinc, vitamin A, vitamin B12, folic acid, and biotin, and an excess of vitamin A; she exhibited a series of signs and symptoms due to these deficiencies and vitamin A overdosage. Nevertheless, careful monitoring of serum levels of trace elements and vitamins and appropriate therapy have almost solved these problems. She has achieved normal physical and mental development and goes to school, while receiving home parenteral nutrition with an ambulatory infusion system.

    Three-dimensional (3D) power Doppler sonographic imaging provides a 3D view of the blood vessels. This technique reportedly has advantages over other forms of sonography in visualizing normal and abnormal fetal vascular anatomy. We report the case of a 36-year-old pregnant woman in whom 3D power Doppler sonography with simultaneous gray-scale imaging was performed at 32 weeks' gestational age to investigate an intestinal obstruction in the fetus that was suspected on the basis of 2-dimensional sonographic findings. The 3D sonograms revealed that the superior mesenteric artery and vein of the fetus were wound counterclockwise, forming the "barber-pole" sign. At 38 weeks' menstrual age, the female infant was delivered vaginally. Only duodenal atresia and annular pancreas, but not intestinal malrotation, were found postnatally. Surgical reconstruction of the duodenum was performed, with no major complications. Previous research suggests that the counterclockwise barber-pole sign is a normal finding. On the basis of our case, we believe that this "negative finding" might be used to exclude the diagnosis of midgut volvulus, a condition that would be expected to cause these vessels to wrap around in a clockwise direction.

  19. Development and Function of Secondary and Tertiary Lymphoid Organs in the Small Intestine and the Colon

    PubMed Central

    2016-01-01

    The immune system of the gut has evolved a number of specific lymphoid structures that contribute to homeostasis in the face of microbial colonization and food-derived antigenic challenge. These lymphoid organs encompass Peyer’s patches (PP) in the small intestine and their colonic counterparts that develop in a programed fashion before birth. In addition, the gut harbors a network of lymphoid tissues that is commonly designated as solitary intestinal lymphoid tissues (SILT). In contrast to PP, SILT develop strictly after birth and consist of a dynamic continuum of structures ranging from small cryptopatches (CP) to large, mature isolated lymphoid follicles (ILF). Although the development of PP and SILT follow similar principles, such as an early clustering of lymphoid tissue inducer (LTi) cells and the requirement for lymphotoxin beta (LTβ) receptor-mediated signaling, the formation of CP and their further maturation into ILF is associated with additional intrinsic and environmental signals. Moreover, recent data also indicate that specific differences exist in the regulation of ILF formation between the small intestine and the colon. Importantly, intestinal inflammation in both mice and humans is associated with a strong expansion of the lymphoid network in the gut. Recent experiments in mice suggest that these structures, although they resemble large, mature ILF in appearance, may represent de novo-induced tertiary lymphoid organs (TLO). While, so far, it is not clear whether intestinal TLO contribute to the exacerbation of inflammatory pathology, it has been shown that ILF provide the critical microenvironment necessary for the induction of an effective host response upon infection with enteric bacterial pathogens. Regarding the importance of ILF for intestinal immunity, interfering with the development and maturation of these lymphoid tissues may offer novel means for manipulating the immune response during intestinal infection or inflammation.

    Human influenza viruses replicate almost exclusively in the respiratory tract, yet infected individuals may also develop gastrointestinal symptoms, such as vomiting and diarrhea. However, the molecular mechanisms remain incompletely defined. Using an influenza mouse model, we found that influenza pulmonary infection can significantly alter the intestinal microbiota profile through a mechanism dependent on type I interferons (IFN-Is). Notably, influenza-induced IFN-Is produced in the lungs promote the depletion of obligate anaerobic bacteria and the enrichment of Proteobacteria in the gut, leading to a "dysbiotic" microenvironment. Additionally, we provide evidence that IFN-Is induced in the lungs during influenza pulmonary infection inhibit the antimicrobial and inflammatory responses in the gut during Salmonella-induced colitis, further enhancing Salmonella intestinal colonization and systemic dissemination. Thus, our studies demonstrate a systemic role for IFN-Is in regulating the host immune response in the gut during Salmonella-induced colitis and in altering the intestinal microbial balance after influenza infection.

    Enteric Duplication Cysts (EDC) is a rare congenital malformation, usually found in mesenteric side of Gastrointestinal (GI) tract. Generally patients present with non-specific symptoms depending on size and location of the cyst in GI tract. EDC presenting as small bowel volvulus is a rare clinical entity. Herein, we are reporting a 16-year-old adolescent girl who presented to Emergency Department (ED) with the features of acute bowel obstruction with septicemia. Patient underwent exploratory laparotomy which revealed dilated, twisted, gangrenous bowel due to a cystic lesion adjacent to the mesenteric side. Resection of the cystic lesion along with the affected gangrenous segment of bowel with an end to end anastomosis performed. PMID:28208934

    The ectopic deposition of fat in liver and muscle during obesity is well established, however surprisingly little is known about the intestine. We used the ob/ob mouse and C57BL6/J mice fed a high fat (HF) diet to examine the effects of obesity and the effects of HF feeding, respectively, on intestinal mucosal triacylglycerol (TG) accumulation. Male C57BL6/J (wild-type, WT) mice were fed low fat (LF; 10% kcal as fat) or HF (45%) diets, and ob/ob mice were fed the LF diet, for 3 weeks. In this time frame, the WT–HF mice did not become obese, enabling independent examination of effects of the HF diet and effects of obesity. Analysis of intestinal lipid extracts from fed and fasted animals demonstrated that the mucosa, like other tissues, accumulates excess lipid. In the fed state, mucosal triacylglycerol (TG) levels were threefold and fivefold higher in the WT–HF and ob/ob mice, respectively, relative to the WT–LF mice. In the fasted state, mucosa from ob/ob mice had threefold higher TG levels relative to WT–LF mucosa. q-PCR analysis of mucosal mRNA from fed state mice showed alterations in the expression of several genes related to both anabolic and catabolic lipid metabolism pathways in WT–HF and ob/ob mice relative to WT–LF controls. Fewer changes were found in mucosal samples from the fasted state animals. Remarkably, oral fat tolerance tests showed a striking reduction in the plasma appearance of an oral fat load in the ob/ob and WT–HF mice compared to WT–LF. Overall, the results demonstrate that the intestinal mucosa accumulates excess TG during obesity. Changes in the expression of lipid metabolic and transport genes, as well as reduced secretion of dietary lipid from the mucosal cells into the circulation, may contribute to the TG accumulation in intestinal mucosa during obesity. Moreover, even in the absence of frank obesity, HF feeding leads to a large decrease in the rate of intestinal lipid secretion. PMID:22375121

    Intestinal permeability (IP) to /sup 51/Cr ethylenediamine tetraacetic acid was investigated in 47 children with chronic obstructive respiratory disease (CORD). Endoscopic duodenal biopsies were performed in 22 of these patients. IP was significantly increased in CORD patients when compared to either control children or adults (P less than 0.001). Mean +/- 1 SD were 4.3 +/- 1.71%, 2.5 +/- 0.78%, and 2.3 +/- 0.77% in the three groups, respectively. IP was not related to the presence of atopy. Significant differences in IP results were found between CORD children with abdominal pain (4.5 +/- 1.4%) and both control children and CORD patients without abdominal pain (2.5 +/- 0.78% and 3.2 +/- 1.49%, respectively). A significant correlation was found between small bowel injury on the one hand and IP on the other hand (P less than 0.02). Furthermore, small bowel injury was significantly related to the presence of abdominal pain (P less than 0.05). We speculate that in CORD patients with abdominal pain, a factor exists that causes small bowel injury responsible for both abdominal pain and increased small bowel permeability. Food intolerance could, presumably, play a role in the mucosal damage-linked IP increase found in the subset of CORD patients who complain of abdominal pain.

    Introducción: la elección de una incisión para laparotomía depende del área que necesite ser expuesta, la urgencia del procedimiento y las preferencias del cirujano. En el Hospital de Pediatría del Centro Médico Nacional Siglo XXI del IMSS, tradicionalmente se realiza abordaje por línea media en estos pacientes. Nuestro objetivo fue determinar si el abordaje por línea media es seguro para el manejo de neonatos sometidos a laparotomía por oclusión intestinal. Métodos: estudio retrospectivo que incluyó a todos los neonatos sometidos a laparotomía por oclusión intestinal mediante abordaje por línea media, en un período comprendido entre enero 2010 a enero 2012. Resultados: se estudiaron 34 pacientes. El 88.2 % de los procedimientos fueron de urgencia. Se encontraron complicaciones en 44 % de los pacientes, de las cuales la más frecuentes fueron: infección y dehiscencia de herida. Dentro de las complicaciones respiratorias, el 32.4 % presentó atelectasia y el 14.7 %, neumonía. Tuvieron hernia postincisional al año el 14.7 %. Ninguna de las variables del paciente o la cirugía fueron estadísticamente significativas para el desarrollo de complicaciones. Se presentaron más complicaciones en los procedimientos de urgencia, en pacientes menores a 2000 gramos y con tiempos quirúrgicos mayores a 120 minutos. Conclusiones: la frecuencia de complicaciones inmediatas y mediatas posteriores al evento quirúrgico son mayores a las reportadas en la literatura con abordaje transverso. La frecuencia de hernia postincisional al año es similar a lo reportado con éste último abordaje.

    Colonic adenocarcinoma is a common gastrointestinal malignancy affecting the elderly, and has a multifactorial aetiology. Depending on the individual circumstances, surgical resection is the treatment of choice for colon cancer even for oligometastasis. Metastatic evidence as well as presence of comorbidities, particularly in the elderly, make surgical management difficult and often present a clinical challenge for clinicians. This is a case report exploring the treatment options for an 80-year-old male patient presenting with acute large bowel obstruction secondary to colonic adenocarcinoma with disseminated metastases and severe aortic stenosis.

    Intestinal lymphangiectasia in the adult may be characterized as a disorder with dilated intestinal lacteals causing loss of lymph into the lumen of the small intestine and resultant hypoproteinemia, hypogammaglobulinemia, hypoalbuminemia and reduced number of circulating lymphocytes or lymphopenia. Most often, intestinal lymphangiectasia has been recorded in children, often in neonates, usually with other congenital abnormalities but initial definition in adults including the elderly has become increasingly more common. Shared clinical features with the pediatric population such as bilateral lower limb edema, sometimes with lymphedema, pleural effusion and chylous ascites may occur but these reflect the severe end of the clinical spectrum. In some, diarrhea occurs with steatorrhea along with increased fecal loss of protein, reflected in increased fecal alpha-1-antitrypsin levels, while others may present with iron deficiency anemia, sometimes associated with occult small intestinal bleeding. Most lymphangiectasia in adults detected in recent years, however, appears to have few or no clinical features of malabsorption. Diagnosis remains dependent on endoscopic changes confirmed by small bowel biopsy showing histological evidence of intestinal lymphangiectasia. In some, video capsule endoscopy and enteroscopy have revealed more extensive changes along the length of the small intestine. A critical diagnostic element in adults with lymphangiectasia is the exclusion of entities (e.g. malignancies including lymphoma) that might lead to obstruction of the lymphatic system and "secondary" changes in the small bowel biopsy. In addition, occult infectious (e.g. Whipple's disease from Tropheryma whipplei) or inflammatory disorders (e.g. Crohn's disease) may also present with profound changes in intestinal permeability and protein-losing enteropathy that also require exclusion. Conversely, rare B-cell type lymphomas have also been described even decades following initial

    2017-01-01

    Neuroendocrine Carcinoma of the Prostate (NECP) is rare and only few cases have been reported, constituting less than 0.5% of prostatic malignancies. We report a rare case of large bowel obstruction from NECP posing a further challenge in management due to resistant hypokalaemia. A 70-year-old man presented with clinical signs of large bowel obstruction who was known to have prostatic carcinoma three years ago, treated initially with hormone therapy then chemoradiation. The blood profile showed a severe hypokalaemia and CT scan revealed liver and lung metastases apart from confirming large bowel obstruction from local invasion of NECP. Severe hypokalaemia was believed to be caused by paraneoplastic syndrome from tumor burden or by recent administration of Etoposide. Intensive potassium correction through a central venous access in maximal doses of 150 mmol/24 hours under cardiac monitoring finally raised serum potassium to 3.8 mmol/L. This safe period allowed us to perform a trephine colostomy at the left iliac fossa. The postoperative period was relatively uneventful. This first case report is presenting a rare cause of large bowel obstruction from a neuroendocrine carcinoma of prostate and highlights the importance of an early, intensive correction of electrolytes in patients with large tumor burden from NECP.

    Aim The aim of this study was to report the preliminary experience with the techniques and utility of navigation-guided, 3D, computed tomography–dacryocystography (CT-DCG) in the management of secondary acquired lacrimal drainage obstructions. Methods Stereotactic surgeries using CT-DCG as the intraoperative image-guiding tool were performed in 3 patients. One patient had nasolacrimal duct obstruction (NLDO) following a complete maxillectomy for a sinus malignancy, and the other 2 had NLDO following extensive maxillofacial trauma. All patients underwent a 3D CT-DCG. Image-guided dacryolocalization (IGDL) was performed using the intraoperative image-guided StealthStation™ system in the electromagnetic mode. All patients underwent navigation-guided powered endoscopic dacryocystorhinostomy (DCR). The utility of intraoperative dacryocystographic guidance and the ability to localize the lacrimal drainage system in the altered endoscopic anatomical milieu were noted. Results Intraoperative geometric localization of the lacrimal sac and the nasolacrimal duct could be easily achieved. Constant orientation of the lacrimal drainage system was possible while navigating in the vicinity of altered endoscopic perilacrimal anatomy. Useful clues with regard to modifications while performing a powered endoscopic DCR could be obtained. Surgeries could be performed with utmost safety and precision, thereby avoiding complications. Detailed preoperative 3D CT-DCG reconstructions with constant intraoperative dacryolocalization were found to be essential for successful outcomes. Conclusion The 3D CT-DCG-guided navigation procedure is very useful while performing endoscopic DCRs in cases of secondary acquired and complex NLDOs. PMID:28115826

    A 10-yr-old, captive, intact male Asian small-clawed otter (Amblonyx cinereus) with a history of bilateral nephrolithiasis was presented for acute-onset lethargy and inappetance of 5 days duration. On physical examination, the otter was about 8% dehydrated and a palpable fluid wave was present in the abdomen. An abdominal ultrasound revealed hydronephrosis of the left kidney and a hyperechoic structure present within the lumen of the left ureter, causing an obstruction. A urinalysis revealed struvite crystalluria, bacteriuria, and an elevated pH. Following 4 days of antibiotic therapy, a left ureteronephrectomy was performed. Upon opening the kidney to retrieve calculi, a large amount of purulent material was noted within the renal pelvis. To the authors' knowledge, this is the first documented case of a nephrectomy in an Asian small-clawed otter. Nephrectomy should be considered as a viable option for treatment of ureteral obstruction, hydronephrosis, or severe pyelonephritis.

    This laboratory recently identified a human gene that encodes a novel folate transporter [Homo sapiens proton-coupled folate transporter (HsPCFT); SLC46A1] required for intestinal folate absorption. This study focused on mouse (Mus musculus) PCFT (MmPCFT) and rat (Rattus norvegicus) PCFT (RnPCFT) and addresses their secondary structure, specificity, tissue expression, and regulation by dietary folates. Both rodent PCFT proteins traffic to the cell membrane with the NH(2)- and COOH-termini accessible to antibodies targeted to these domains only in permeabilized HeLa cells. This, together with computer-based topological analyses, is consistent with a model in which rodent PCFT proteins likely contain 12 transmembrane domains. Transport of [(3)H]folates was optimal at pH 5.5 and decreased with increasing pH due to an increase in K(m) and a decrease in V(max). At pH 7.0, folic acid and methotrexate influx was negligible, but there was residual (6S)5-methyltetrahydrofolate transport. Uptake of folates in PCFT-injected Xenopus oocytes was electrogenic and pH dependent. Folic acid influx K(m) values of MmPCFT and RnPCFT, assessed electrophysiologically, were 0.7 and 0.3 microM at pH 5.5 and 1.1 and 0.8 microM at pH 6.5, respectively. Rodent PCFTs were highly specific for monoglutamyl but not polyglutamyl methotrexate. MmPCFT mRNA was highly expressed in the duodenum, proximal jejunum, liver, and kidney with lesser expression in the brain and other tissues. MmPCFT protein was localized to the apical brush-border membrane of the duodenum and proximal jejunum. MmPCFT mRNA levels increased approximately 13-fold in the proximal small intestine in mice fed a folate-deficient vesus folate-replete diet, consistent with the critical role that PCFT plays in intestinal folate absorption.

    Small bowel obstruction and large bowel obstruction account for approximately 20% of cases of acute abdominal surgical conditions. The role of the radiologist is to answer several key questions: Is obstruction present? What is the level of the obstruction? What is the cause of the obstruction? What is the severity of the obstruction? Is the obstruction simple or closed loop? Is strangulation, ischemia, or perforation present? In this presentation, the radiologic approach to and imaging findings of patients with known or suspected bowel obstruction are presented.

    The article reviews the intestinal ischemia theme on newborn and children. The intestinal ischemia may be either acute - intestinal infarction (by vascular obstruction or by reduced mesenteric blood flow besides the occlusive mechanism), either chronic. In neonates, acute intestinal ischemia may be caused by aortic thrombosis, volvulus or hypoplastic left heart syndrome. In children, acute intestinal ischemia may be caused by fibromuscular dysplasia, volvulus, abdominal compartment syndrome, Burkitt lymphoma, dermatomyositis (by vascular obstruction) or familial dysautonomia, Addison's disease, situs inversus abdominus (intraoperative), burns, chemotherapy administration (by nonocclusive mesenteric ischemia). Chronic intestinal ischemia is a rare condition in pediatrics and can be seen in abdominal aortic coarctation or hypoplasia, idiopathic infantile arterial calcinosis.

    Mesenteric venous thrombosis is a rare cause of intestinal ischemia which is potentially life-threatening because it can lead to intestinal infarction. Mesenteric venous thrombosis rarely develops after abdominal surgery and is usually associated with coagulation disorders. Associated symptoms are generally subtle or nonspecific, often resulting in delayed diagnosis. A 68-year-old woman underwent laparoscopic exploration for small bowel obstruction, secondary to adhesions. During the procedure, an intestinal perforation was identified and repaired. Postoperatively, the abdominal pain persisted and repeat exploration was undertaken. At repeat exploration, a perforation was identified in the small bowel with a surrounding abscess. After the second operation, the abdominal pain improved but anorexia persisted. Contrast enhanced abdominal computed tomography was performed which revealed superior mesenteric venous thrombosis. Anticoagulation therapy with heparin was started immediately and the thrombus resolved over the next 6 days. Although rare, this complication must be considered in patients after abdominal surgery with unexplained abdominal symptoms. PMID:24455391

    "Obstructive uropathy" is a generic term which combines different diseases in infants and childhood. Both the upper and lower urinary tract may be affected. Diseases of the urinary tract can cause an intrinsic obstruction. Sometimes tumours may cause a compression and as secondary effect an obstruction (extrinsic). Ultrasound is the key diagnostic tool and shows dilatation of the obstructed urinary tract. But for the functional exploration of babies and toddlers, renal scanning and X-ray examinations are necessary. These examinations lead to an exposure to radiation which necessitates careful indication. Some of the congenital diseases (for example ureteropelvic junction obstruction, megaureter) show a maturation without any intervention. So one has to decide whether to wait and see or to operate. A percutaneous nephrostomy or a DJ-catheter is not often used in the treatment of obstruction in general. These forms of drainage are more often used in the treatment of stones or of extrinsic obstruction. A pyelocutaneostomy or ureterocutaneostomy is a special surgical procedure in pediatric urology for transient drainage of the upper urinary tract (megaureter). The operation of a seriously ill new-born should be done in a centre for pediatric urology and pediatric nephrology. When the upper urinary tract is dilated, patients may need an antibiotic prophylaxis, because the dilatation of the upper urinary tract increases the risk of urinary tract infections (UTI). The indication for antibiotic prophylaxis should by guided by the criteria of the APN-Consensus Paper. Long-term follow-up is necessary and should comprise ultrasound, physical examination, controlling the blood pressure, urine analysis and blood tests. The aims of diagnostics, treatment and long-term follow-up are the preservation of renal function and to protect the children from UTI. This goal must be reached under conditions that are appropriate for children and their parents.

  18. Electrophysiological principles of motility disturbances in the small and large intestines--review of the literature and personal experience.

    Motility disturbances of the small and large intestines are based on changes in the smooth-muscle potential, whereby the number of amplitudes and configuration of slow waves and of spike potentials as well as pattern, speed of propagation, and duration of the MMC are of crucial importance. Whereas the electromechanical principles of intestinal motility are sufficiently known, changes in the electromechanical activity in clinically manifest motility disturbances have as yet not been given due regard. Only recently, electromechanical measurements in the upper gastrointestinal tract and colon were performed in several gastrointestinal diseases of internal medicine. In the small intestine, changes in slow waves, spike potentials, and the MMC could be disclosed which are typical for hyperthyrosis, hypothyrosis, irritable bowel syndrome, bacterial diarrhea, primary and secondary intestinal pseudo-obstruction, short-bowel syndrome, postoperative bowel atonia, mechanical bowel obstruction, vagotomy, and diabetic enteropathy with disturbed gastric emptying. Regarding the colon, a disturbance in the electromechanical characteristics was found in irritable bowel syndrome, bacterial overgrowth in the small bowel, chronic constipation, and idiopathic intestinal pseudo-obstruction, which is probably identical with the clinical picture of adynamic ileus. Based on a thorough examination of the literature and on own results from electromechanical measurements in children, electromechanical disturbances have been narrowly defined.

    A bezoar is a concretion of foreign or indigestible matter in the alimentary canal and is usual cause of gastric obstruction. Bezoars can become fragmented and migrate downward leading to intestinal obstruction. Diagnosis of phytobezoar has become challenging in clinical practice due to lack of patient history and inability of patient to correlate preceding events with the episode of bowel obstruction. Bezoar associated small bowel obstruction rarely occurs and is usually found in patients with history of gastrointestinal surgery. Very few cases are reported of small bowel obstruction due to bezoar in healthy population without prior illness or surgery. We present a case of small bowel obstruction due to mushroom bezoar in a 62-year patient with no past history of medical illness or gastric surgery. Enterotomy was performed and a whole piece of undigested mushroom measuring 5 x 3 cm was successfully removed.

    A 13-yr-old male African black-footed penguin (Spheniscus demersus) presented thrice over 7 mo with gastrointestinal obstruction secondary to cloacolithiasis. Clinical signs consistently resolved with cloacolith removal and supportive care. However, 10 mo after initial presentation, it presented with similar signs, plus significant weight loss. No cloacolith was found, and it subsequently died. Significant gross findings included bilateral cecal masses, colonic perforation, and marked secondary coelomitis, multifocal tan to pale hepatic nodules, and pale kidneys with miliary white foci. Histopathologic diagnoses were intestinal lymphosarcoma with hepatic and renal metastases, secondary intestinal rupture, and subacute severe bacterial coelomitis. To the authors' knowledge, this is the first full report of either cloacolithiasis or lymphosarcoma in a penguin.

    Purpose To determine whether adding unenhanced computed tomography (CT) to contrast material-enhanced CT improves the diagnostic performance of decreased bowel wall enhancement as a sign of ischemia complicating mechanical small bowel obstruction (SBO). Materials and Methods This retrospective study was approved by the institutional review board, which waived the requirement for informed consent. Two gastrointestinal radiologists independently performed retrospective assessments of 164 unenhanced and contrast-enhanced CT studies from 158 consecutive patients (mean age, 71.2 years) with mechanical SBO. The reference standard was the intraoperative and/or histologic diagnosis (in 80 cases) or results from clinical follow-up in patients who did not undergo surgery (84 cases). Decreased bowel wall enhancement was evaluated with contrast-enhanced images then and both unenhanced and contrast-enhanced images 1 month later. Diagnostic performance of decreased bowel wall enhancement and confidence in the diagnosis were compared between the two readings by using McNemar and Wilcoxon signed rank tests. Interobserver agreement was assessed by using κ statistics and compared with bootstrapping. Results Ischemia was diagnosed in 41 of 164 (25%) episodes of SBO. For both observers, adding unenhanced images improved decreased bowel wall enhancement sensitivity (observer 1: 46.3% [19 of 41] vs 65.8% [27 of 41], P = .02; observer 2: 56.1% [23 of 41] vs 63.4% [26 of 41], P = .45), Youden index (from 0.41 to 0.58 for observer 1 and from 0.42 to 0.61 for observer 2), and confidence score (P < .001 for both). Specificity significantly increased for observer 2 (84.5% [104 of 123] vs 94.3% [116 of 123], P = .002), and interobserver agreement significantly increased, from moderate (κ = 0.48) to excellent (κ = 0.89; P < .0001). Conclusion Adding unenhanced CT to contrast-enhanced CT improved the sensitivity, diagnostic confidence, and interobserver agreement of the diagnosis of ischemia

    Unilateral ureteral obstruction is a popular experimental model of renal injury. However, the study of the kidney response to urinary tract obstruction is only one of several advantages of this model. Unilateral ureteral obstruction causes subacute renal injury characterized by tubular cell injury, interstitial inflammation and fibrosis. For this reason, it serves as a model both of irreversible acute kidney injury and of events taking place during human chronic kidney disease. Being a unilateral disease, it is not useful to study changes in global kidney function, but has the advantage of a low mortality and the availability of an internal control (the non-obstructed kidney). Experimental unilateral ureteral obstruction has illustrated the molecular mechanisms of apoptosis, inflammation and fibrosis, all three key processes in kidney injury of any cause, thus providing information beyond obstruction. Recently this model has supported key concepts on the role in kidney fibrosis of epithelial-mesenchymal transition, tubular epithelial cell G2/M arrest, the anti-aging hormone Klotho and renal innervation. We now review the experimental model and its contribution to identifying novel therapeutic targets in kidney injury and fibrosis, independently of the noxa.

    Morphometric techniques were used in the evaluation of lymphocyte morphology and activity in tropical sprue. jejunal biopsies from control subjects (8), patients with epidemic disease (7), patients with endemic disease (11), and subjects who had recovered from sprue (4) were analyzed blindly. In patients with sprue, lymphocytes were increased significantly within crypt (but not surface) epithelium. Immunoblasts (greater than 6 mu in diameter) were increased by 5% over control subjects. Group means for lymphocytic mitotic indexes were also significantly raised, while flux ratios only differed significantly between endemic sprue patients and control subjects. The lymphocytic infiltration was distributed focally in the upper crypt and crypt-villus interzones. Analysis of epidemic cases (presenting within 4-28 days) revealed detectable changes in lymphocyte behavior only after 3 weeks' illness, whereas mucosal lesions and malabsorption were already established during the first week. These data indicate that lymphocyte activation, suggestive of a local cell-mediated immune reaction, does occur in tropical sprue but is secondary to damage already inflicted on enterocytes and their function.

    Small bowel obstruction is a common condition encountered by the radiologist in the emergency department. Though intestinal adhesions and obstructed hernias are the most common causes of acute small bowel obstruction, a variety of uncommon and rare conditions can cause acute and subacute bowel obstruction. Imaging plays a key role in the workup of bowel obstruction by identifying the cause, level, and degree of bowel obstruction. In this article, we present a comprehensive review of the multi-detector computed tomography features of common and uncommon causes of acute and subacute small bowel obstruction.

    Intestinal ischemia-reperfusion (I/R) injury is a serious clinical pathophysiological process that may result in acute local intestine and remote liver injury. Protocatechuic acid (PCA), which has been widely studied as a polyphenolic compound, induces expression of antioxidative genes that combat oxidative stress and cell apoptosis. In this study, we investigated the effect of PCA pretreatment for protecting intestinal I/R-induced local intestine and remote liver injury in mice. Intestinal I/R was established by superior mesenteric artery occlusion for 45 min followed by reperfusion for 90 min. After the reperfusion period, PCA pretreatment markedly alleviated intestine and liver injury induced by intestinal I/R as indicated by histological alterations, decreases in serological damage parameters and nuclear factor-kappa B and phospho-foxo3a protein expression levels, and increases in glutathione, glutathione peroxidase, manganese superoxide dismutase protein expression, and Bcl-xL protein expression in the intestine and liver. These parameters were accompanied by PCA-induced adaptor protein p66shc suppression. These results suggest that PCA has a significant protective effect in the intestine and liver following injury induced by intestinal I/R. The protective effect of PCA may be attributed to the suppression of p66shc and the regulation of p66shc-related antioxidative and antiapoptotic factors.

    Preduodenal portal vein is a rare congenital anomaly that causes high intestinal obstruction. The authors report on a newborn who was diagnosed as having duodenal obstruction at 30 weeks' gestation. During surgery the patient was found to have duodenal obstruction caused by a preduodenal portal vein. Malrotation was an associated finding. Treatment consisted of Ladd's procedure and a diamond-shaped duodenoduodenostomy performed anterior to the portal vein.

    Eleven patients with an obstructed, fluid-filled uterus, due to carcinoma of the uterus or to its treatment by radiation therapy, were examined with computed tomography (CT) and/or ultrasound. It is important to recognize this abnormality to differentiate it from other causes of pelvic mass and to ensure prompt treatment of pyometra, should it develop. Both CT and ultrasound reliably identified this condition and differentiated it from other pelvic masses.

    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 4×3×2.5 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. PMID:26473140

    A 70 year old lady presented to surgery emergency with small bowel obstruction without any obvious etiology. On exploration she was found to have an obstructed obturator hernia, which is a rare pelvic hernia with an incidence of 0.07-1.4% of all intra-abdominal hernias. Diagnosis is often delayed until laparotomy for bowel obstruction. Strangulation is frequent and mortality remains high (25%). Early diagnosis and surgical treatment contributes greatly to reduce the mortality and morbidity rates. A variety of techniques have been described, however surgical repair has not been standardized. It is an important diagnosis to be considered in elderly patients with intestinal obstruction. PMID:27763487

    Choroid plexus cysts are common and typically asymptomatic abnormal folds of the epithelial lining of the choroid plexus. Rarely, these cysts may gradually enlarge and cause outflow obstruction of cerebrospinal fluid. The authors present a case of a large choroid plexus cyst causing acute hydrocephalus in a previously healthy 2-year-old boy. The patient presented with markedly declining mental status, vomiting, and bradycardia over the course of several hours. Computed tomography scans demonstrated enlarged lateral and third ventricles with sulcal effacement, but no obvious mass lesions or hemorrhage. There was no antecedent illness or trauma. A right frontal external ventricular drain was placed in the patient, resulting in decompression of only the right lateral ventricle. Magnetic resonance (MR) imaging demonstrated a lobulated cyst arising from the choroid plexus of the left lateral ventricle and herniating through the foramen of Monro into the third ventricle, occluding both the foramen of Monro and the cerebral aqueduct. The patient underwent an endoscopic fenestration of the cyst, and histological results confirmed that it was a choroid plexus cyst. Postoperative MR imaging showed a marked reduction in the cyst size. The cyst was no longer in the third ventricle, the foramen of Monro and the aqueduct were patent, and the ventricles were decompressed. The patient was discharged home with no deficits. To the authors' knowledge, there are no previous reports of a choroid plexus cyst causing acute hydrocephalus due to herniation into the third ventricle. This case is illustrative because it describes this entity for the first time, and more importantly highlights the need to obtain a diagnosis when a patient presents with acute hydrocephalus without a clear cause.

  17. Long-term outcomes after stenting as a “bridge to surgery” for the management of acute obstruction secondary to colorectal cancer

    2016-01-01

    Obstructive symptoms are present in 8% of cases at the time of initial diagnosis in cases of colorectal cancer. Emergency surgery has been classically considered the treatment of choice in these patients. However, in the majority of studies, emergency colorectal surgery is burdened with higher morbidity and mortality rates than elective surgery, and many patients require temporal colostomy which deteriorates their quality of life and becomes permanent in 10%-40% of cases. The aim of stenting by-pass to surgery is to transform emergency surgery into elective surgery in order to improve surgical results, obtain an accurate tumoral staging and detection of synchronous lesions, stabilization of comorbidities and performance of laparoscopic surgery. Immediate results were more favourable in patients who were stented concerning primary anastomosis, permanent stoma, wound infection and overall morbidity, having the higher surgical risk patients the greater benefit. However, some findings laid out the possible implication of stenting in long-term results of oncologic treatment. Perforation after stenting is related to tumoral recurrence. In studies with perforation rates above 8%, higher recurrences rates in young patients and lower disease free survival have been shown. On the other hand, after stenting the number of removed lymph nodes in the surgical specimen is larger, patients can receive adjuvant chemotherapy earlier and in a greater percentage and the number of patients who can be surgically treated with laparoscopic surgery is larger. Finally, there are no consistent studies able to demonstrate that one strategy is superior to the other in terms of oncologic benefits. At present, it would seem wise to assume a higher initial complication rate in young patients without relevant comorbidities and to accept the risk of local recurrence in old patients (> 70 years) or with high surgical risk (ASA III/IV).

    1988-10-01

    Epiphora is a common symptom associated with the acute phase of epidemic keratoconjunctivitis (EKC). Reflex lacrimal secretion occurs secondary to conjunctival or corneal inflammation. Acquired obstruction of the lacrimal excretory system may account for persistence of tearing after resolution of the acute inflammatory phase of the viral infection. Three cases of lacrimal excretory system obstruction after EKC are reported. Multifocal obstruction of the canaliculi and nasolacrimal duct is characteristic. Dacryocystorhinostomy (DCR) was required to relieve obstruction in all cases. Probing and corticosteroid irrigation may avoid the need for silicone intubation or conjunctivodacryocystorhinostomy in the management of canalicular obstruction. Persistent epiphora after EKC should raise clinical suspicion of acquired dacryostenosis. Early recognition may allow for optimal management.

    INTRODUCTION Intussusception in adult patients represents 5% of all intussusceptions and 1–5% of bowel obstructions in adults. In contrast to pediatric patients, 90% of the time, in adults, it's caused by well-established pathologic mechanisms, such as carcinoma, polyps, diverticula, Meckel diverticula, stenosis, or benign neoplasms. Small intestine intussusceptions are more frequent, but colonic intussusceptions are caused 50% of the time by malignant neoplasms, especially adenocarcinoma. PRESENTATION OF CASE We present a 70-year-old woman, with no relevant familial history, who presented with a 3-day symptomatology consisting of epigastric, colic, diffuse, abdominal pain of moderate intensity, which progressed till reaching a severe intensity, also referring abdominal distension, nausea, and gastrointestinal-content vomits. DISCUSSION In adult patients, the exact mechanism of intussusception is unknown in 8–20% of the cases, however, secondary intussusception can occur with any lesion of the intestinal wall or any irritant factor in its lumen that alters normal peristaltic activity and that could serve as a trigger to start an intussusception of one bowel segment over another the most common site is the small intestine. CONCLUSION Intussusception represents an unusual problem in adult patients; it requires a high clinical suspicion, mainly as a differential diagnosis in patients with intestinal obstruction, and it clinically presents as a subacute or chronic illness. CT represents the most useful diagnostic tool. An attempt to perform reduction procedures in small intestine intussusceptions can be done, however, in ileocolic or colonic intussusceptions, a formal resection of the segment is recommended.

    The nasogastric tube (NGT) has become a frequently used device to alleviate gastrointestinal symptoms. Nasogastric tube syndrome (NTS) is an uncommon but potentially life-threatening complication of an indwelling NGT. NTS is characterized by acute upper airway obstruction due to bilateral vocal cord paralysis. We report a case of a 76-year-old man with NTS, induced by an indwelling long intestinal tube. He was admitted to our hospital for treatment of sigmoid colon cancer. He underwent sigmoidectomy to release a bowel obstruction, and had a long intestinal tube inserted to decompress the intestinal tract. He presented acute dyspnea following prolonged intestinal intubation, and bronchoscopy showed bilateral vocal cord paralysis. The NGT was removed immediately, and tracheotomy was performed. The patient was finally discharged in a fully recovered state. NTS be considered in patients complaining of acute upper airway obstruction, not only with a NGT inserted but also with a long intestinal tube.

    Ascaris Lumbricoides is the most common worm found in human beings and it is the largest of the intestinal nematodes parasitizing humanity. The most common complication of Ascariasis is mechanical bowel obstruction caused by a large number of worms. Bowel obstruction can also be caused by various toxins released by the worms. A large worm bolus can also cause volvulus or intussusception. We report a case of Intestinal Obstruction due to an Ileal MZBCL in an Ascaris. Lumbricoides infestation setting.

    Urethral obstruction is a common medical emergency in cats. Frequency of post-obstruction diuresis in cats following resolution of urethral obstruction is unknown. The objective of this study was to document frequency and associated clinical features of post-obstruction diuresis in cats. The records of 32 cats undergoing 33 admissions to the Colorado State University Veterinary Hospital for urethral obstruction were reviewed. Signalment, admission blood values, fluid therapy, and urine output were recorded. Diuresis was defined as urine output greater than 2ml/kg/h. Post-obstructive diuresis occurred in 46% (13/28) of cats within the first 6h of treatment. Occurrence of post-obstructive diuresis was statistically more likely in cats with venous pH<7.35 on admission. Urine production following resolution of urethral obstruction should be monitored so that fluid therapy can be adjusted to the individual patient, as many cats will have a higher fluid requirement secondary to post-obstruction diuresis.

    Ascaris lumbricoides is the largest and most prevalent helminth seen in the human body. Ascariasis having high morbidity and mortality causes a unique type of intestinal obstruction with specific problems. This is probably due to reduced intestinal absorption and luminal obstruction, which can lead to anorexia and blockage of the absorbing surface. It affects humans especially in developing countries. This essay presented a 78-year-old female case had severe abdominal pain, nausea and constipation for seven days and the pylorus was obstructed by A. lumbricoides and diagnosis was obtained by endoscopy. During endoscopy in the treatment, the ascariasis that could be removed was. Afterwards, 100 mg mebendazole was given for 3 days once in two months.The purpose of the presentation of this case is that it is seen in advanced ages and it sets us thinking of stomach tumor due to its obstruction and anemia clinic.

    Duplex-Doppler sonography could be employed in the quantitative investigation of intestinal motility. Preliminary data indicate reproductivity of the method in normal subjects and possible clinical applications in some pathological conditions affecting intestinal transit. Particularly, the possibility to discriminate between segments at different peristaltic activity seems to be very useful in intestinal obstruction. Further studies are necessary to validate this method.

    Primary enterolithiasis is a rare surgical ailment. The underlying cause is intestinal stasis. Numerous anatomical and micro environmental factors such as enteritis, incarcerated hernia, malignancy, diverticula, blind loops, and enteroenterostomy predispose to clinically significant concretions. Enterolithiasis in tuberculosis can be due to the presence of strictures, intestinal bands, or interbowel/parietal adhesions, leading to intestinal stasis. Secondary enterolithiasis is generally caused by gallstones or renal stones migrating to the gastrointestinal tract due to fistula formation. During stasis, food particles act as a nidus and calcium salts are deposited over the food particles, leading to stone formation. A 57-year-old male patient presented to the Emergency Department of Jawaharlal Nehru Medical College, AMU, Aligarh, with features of intestinal obstruction. The patient underwent emergency laparotomy, revealing 2 strictures in the distal ileum with 15.24cm of the bowel between them containing a 2×2 cm enterolith. The strictured segment was resected, and end ileostomy and mucus fistula were created. The patient’s postoperative recovery was fine, and he wasdischarged with ileostomy on antitubercular treatment (after histopathologicalconfirmation). Ileostomy closure wasplanned after 6 weeks. The incidence and prevalence of enterolithiasis has been on the rise recently because of advancement in radiological imaging studies. Endoscopic and surgical stone removal along with the treatment of the underlying pathology is recommended. PMID:27853338

    Intestinal anastomosis is a surgical procedure that restores bowel continuity after surgical resection to treat intestinal malignancy, inflammation, or obstruction. Despite the routine nature of intestinal anastomosis procedures, the rate of complications is high. Standard visual inspection cannot distinguish the tissue subsurface and small changes in spectral characteristics of the tissue, so existing tissue anastomosis techniques that rely on human vision to guide suturing could lead to problems such as bleeding and leakage from suturing sites. We present a proof-of-concept study using a portable multispectral imaging (MSI) platform for tissue characterization and preoperative surgical planning in intestinal anastomosis. The platform is composed of a fiber ring light-guided MSI system coupled with polarizers and image analysis software. The system is tested on ex vivo porcine intestine tissue, and we demonstrate the feasibility of identifying optimal regions for suture placement.

    A 22-year-old male sustained C-6 tetraplegia in 1992. In 1993, intravenous pyelography revealed normal kidneys. Suprapubic cystostomy was performed. He underwent open cystolithotomy in 2004 and 2008. In 2009, computed tomography revealed bilateral renal calculi. Coagulum pyelolithotomy of left kidney was performed. Pleura and peritoneum were opened. Peritoneum could not be closed. Following surgery, he developed pulmonary atelectasis; he required tracheostomy and mechanical ventilation. He did not tolerate nasogastric feeding. CT of abdomen revealed bilateral renal calculi and features of proximal small bowel obstruction. Laparotomy revealed small bowel obstruction due to dense inflammatory adhesions involving multiple small bowel loops which protruded through the defect in sigmoid mesocolon and fixed posteriorly over the area of previous intervention. All adhesions were divided. The wide defect in mesocolon was not closed. In 2010, this patient again developed vomiting and distension of abdomen. Laparotomy revealed multiple adhesions. He developed chest infection and required ventilatory support again. He developed pressure sores and depression. Later abdominal symptoms recurred. This patient's general condition deteriorated and he expired in 2011. Conclusion. Risk of postoperative complications could have been reduced if minimally invasive surgery had been performed instead of open surgery to remove stones from left kidney. Suprapubic cystostomy predisposed to repeated occurrence of stones in urinary bladder and kidneys. Spinal cord physicians should try to establish intermittent catheterisation regime in tetraplegic patients. PMID:23533931

    Physicians are educated with the classical teaching that symptomatic patients with Meckel's diverticulum (MD) most often present with painless rectal bleeding. However, a review of the literature reveals that young patients with MD will most commonly present with signs of intestinal obstruction, an etiology not frequency considered in patients presenting to the emergency department with obstruction. We present two cases of intestinal obstruction diagnosed in our emergency department, with Meckel's diverticulum being the etiology. PMID:26788380

    Introduction Small bowel obstruction in a virgin abdomen is an uncommon surgical condition. While malignancy, inflammatory bowel disease and foreign body are the main reported causes, undigested food bezoar causing bowel obstruction is a rare entity. We report a case of small bowel obstruction secondary to dried preserved apple having re-expanded within the gastrointestinal tract. Presentation of case A 69 year old male presented with severe abdominal distension, generalized abdominal tenderness and obstipation for 1 week. Small bowel obstruction (SBO) was confirmed on plain abdominal X-ray and CT imaging. An emergency explorative laparatomy identified a sausage-shaped intra-luminal foreign body obstructing the distal ileum. An enterotomy was performed which revealed a rehydrated, donut-shaped piece of dried apple. Discussion Swallowed items that pass through the pylorus rarely cause obstruction as they are usually small enough to pass through the rest of the bowel without difficulty. We postulate that in our patient that the dried apple was originally small enough to pass through the pylorus. However during small bowel, its’ highly absorbable nature resulted in an increase in size that prevented its’ passage through the ileocecal valve. A simple in-vitro experiment discovered that dried apple has a potential to reabsorb fluid and expand up to 35% of its initial size within 72 h. Conclusion This report illustrates the potential for dried food substances to cause intra-luminal SBO after significant expansion with rehydration. PMID:25841159

    1981-01-01

    Intestinal obstruction as a complication of pancreatitis is infrequently recognized. Only four cases of idiopathic duodenal obstruction associated with pancreatitis have been previously reported. In a three-year study of 878 patients with pancreatitis, nine cases of idiopathic duodenal obstruction associated with pancreatitis have been found. Each of the nine cases was characterized by frank obstruction in the second or third portions of the duodenum and an intact mucosa in the area of stricture. Four patients gave an abrupt history of moderately severe pancreatitis. Resolution of the duodenal obstruction occurred by three weeks in each of these four cases. Surgical exploration in one of these patients revealed marked duodenal edema with intramural hematoma. The remaining five patients reported a chronic history of obstruction. Inadequate resolution of the obstruction after four weeks of hyperalimentation led to surgical bypass. Duodenal biopsy specimens revealed inflammation, muscle destruction, and extensive fibrosis. Duodenal involvement in the inflammatory process of moderately severe pancreatitis was discovered in 25% of the upper gastrointestinal studies, but was usually self-limiting and of a mild degree. Since contiguous duodenal edema is common and fibrosing pancreatoduodenitis only occurs in an occasional patient, surgical intervention for duodenal obstruction associated with pancreatitis should only be considered after demonstrated failure of conservative management.

    Introduction Intestinal malrotation refers to the partial or complete failure of rotation of midgut around the superior mesenteric vessels in embryonic life. Arrested midgut rotation results due to narrow-based mesentery and increases the risk of twisting midgut and subsequent obstruction and necrosis. Presentation of case 40 years old female patient admitted to emergency service with acute abdomen and computerized tomography scan showed dilated large and small intestine segments with air-fluid levels and twisted mesentery around superior mesenteric artery and vein indicating “whirpool sign”. Discussion Malrotation in adults is a rare cause of midgut volvulus as though it should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Even though clinical symptoms are obscure, adult patients usually present with vomiting and recurrent abdominal pain due to chronic partial obstruction. Contrast enhanced radiograph has been shown to be the most accurate method. Typical radiological signs are corkscrew sign, which is caused by the dilatation of various duodenal segments at different levels and the relocation of duodenojejunal junction due to jejunum folding. As malrotation commonly causes intestinal obstruction, patients deserve an elective laparotomy. Conclusion Malrotation should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Surgical intervention should be prompt to limit morbidity and mortality. PMID:27015011

    Internal hernia is a rare cause of bowel obstruction which often requires emergent surgery. In general, the preoperative diagnosis of internal hernia is difficult. The pelvic cavity has various spaces with the potential to result in a hernia, especially in females. In this report, we describe a patient with an internal hernia secondary to previous gynecologic surgery. A 49-year-old woman presented with acute abdominal pain and a history of previous right oophorectomy for a benign ovarian cyst. Computed tomography scan of the abdomen showed obstruction with strangulation and emergent laparoscopic exploration was performed. Intraoperatively, there was an incarcerated internal hernia in the pelvis, located in the vesicouterine pouch, which was reduced. The orifice of the hernia was a 2 cm defect caused by adhesions between the uterus and bladder. The defect was closed with a continuous suture. The herniated bowel was viable, and the operation was completed without intestinal resection. She was discharged four days after surgery without complications. Laparoscopy is useful to diagnose bowel obstruction in selected patients and may also be used for definitive therapy. It is important to understand pelvic anatomy and consider an internal hernia of the pelvic cavity in females, in the differential diagnosis of bowel obstruction, especially those with a history of gynecological surgery.

    Meckel's diverticulum (MD) is a commonly encountered congenital anomaly of the small intestine. We report an extremely unusual case of an axially torted, gangrenous MD presenting as acute intestinal obstruction. A 26-year-old male patient presented to our emergency department with 3 days history of abdominal pain, distention and bilious vomiting. On laparotomy, there was minimal hemorrhagic fluid localized in right iliac fossa and small bowel loops were dilated. A MD was seen attached to the mesentery of nonadjacent small bowel by a peritoneal band. The diverticulum was axially torted and gangrenous. In addition, there was compression of ileum by the peritoneal band resulting in intestinal obstruction, which was relieved on dividing the band. Resection and anastomosis of the small bowel including the MD was performed. We hereby report a rare and unusual complication of a MD. Although treatment outcome is generally good, pre-operative diagnosis is often difficult. PMID:24741431

We report three cases of CSD of the intestine in neonates with varied presentation. First patient was mistaken as pneumoperitoneum on abdominal radiograph, which led to initial abdominal drain placement. The 2nd patient was a case of anorectal malformation associated with congenital pouch colon (CPC) and CSD of ileum; and the third case presented as neonatal intestinal obstruction and found to have CSD of ileum. All the patients were successfully managed in our department. PMID:27896163

  5. Decision Making in Bowel Obstruction: A Review

    PubMed Central

    2016-01-01

    Over the last century there have not been significant changes in the anatomical location of obstruction. The age of presentation has increased along with age related co-morbidity. Management has consequently been challenging as risks keep on increasing with advanced age. Hence, clear decision making has become essential in its management. A selective review of the literature pertaining to common age related aetiologies, diagnosis methods leading to standard decision making and treatment of acute intestinal obstruction was done. The same is obtained from randomized controlled studies, meta-analysis and other related evidence based publications. Predicting the conservative or operative management of Bowel Obstruction (BO) is difficult. BO in young age, in unscarred abdomen and Large Bowel Obstruction (LBO) needs early surgery. Decision on surgery should be taken in paediatric patient by second day and preferably between 3-5 days of admission in adults. Higher American Society of Anaesthesiologists (ASA) grade correlates well with the mortalities. In this article, the timing of surgery, methods to avoid bowel resection and type of surgery in various causes are stressfully analysed and discussed. PMID:28050445

    Small bowel obstruction (SBO) is a common condition encountered in surgical practice. Literature shows divers and many different etiologies for intestinal obstruction. However, bezoars are rarely reported as an etiological factor. A bezoar happens most commonly in patients with impaired gastrointestinal motility. There are four types of bezoars: phytobezoars, trichobezoars, pharmacobezoars and lactobezoars. The most common type is phytobezoars, which are composed of undigested fiber from vegetables or fruits especially persimmons. They are mostly composed of cellulose, tannin and lignin. The commonest phytobezoar reported worldwide is related to the persimmon fruit ingestion. The most common symptom of bezoar-induced SBO is abdominal pain (96–100%). Other common symptoms include nausea and vomiting. Primary small bowel phytobezoars almost always present as SBO. We present an unusual case of SBO caused by a phytobezoar in a 35-year-old patient. Many types of bezoar can be removed endoscopically, but some will require operative intervention. PMID:28031856

    A patient who had undergone gastric resection for carcinoma, had closed loop obstruction of the duodenum due to neoplasia at the duodenojejunal junction. The obstruction was relieved successfully by transhepatic placement of a duodenojejunal stent. We were compelled to use the transhepatic route because a Roux-Y reconstruction had been performed. Transhepatic placement may be the only chance of palliation in a small subset of patients with malignant intestinal obstruction.

    Cardiac tumors are rare and usually indicate metastatic disease. Characterizing a tumor and reaching an exact diagnosis can be difficult. Diagnosis has been aided greatly by advances in imaging, such as cardiovascular magnetic resonance with the use of gadolinium-pentetic acid. Carcinoid tumors are neuroendocrine neoplasms that are found most often in the intestinal tract, although they can also develop in the lung, stomach, or heart. Herein, we report the case of a 72-year-old woman with a history of intestinal carcinoid disease and presenting symptoms of dizziness, fatigue, and chest pain. We used cardiovascular magnetic resonance with gadolinium enhancement to identify a large mass obstructing left ventricular outflow. The histopathologic results of an endomyocardial biopsy confirmed that the mass was a left-sided metastatic carcinoid cardiac tumor. To our knowledge, we are reporting the 1st combined use of clinical evaluation, cardiovascular magnetic resonance, and histopathologic studies to reach such a diagnosis.

  11. Causes, natural history, and incidence of salivary stones and obstructions.

    PubMed

    Harrison, John D

    2009-12-01

    Uncertainty about the causes and natural history of salivary stones (sialoliths) and other obstructions is being dispelled by clinical and experimental research. Sialoliths are now shown to be secondary to chronic obstructive sialadenitis. Microscopic stones (sialomicroliths) accumulate during secretory inactivity in normal salivary glands and produce atrophic foci by obstruction. Microbes ascend the main salivary duct during secretory inactivity and proliferate in atrophic foci and cause spreading inflammation, leading to inflammatory swelling and fibrosis that can compress large ducts. This leads to stagnation of secretory material rich in calcium that precipitates onto degenerating cellular membranes to form a sialolith.

    Previous studies have demonstrated morphological and biomechanical remodeling in the intestine proximal to an obstruction. The present study aimed to obtain stress and strain thresholds to initiate contraction and the maximal contraction stress and strain in partially obstructed guinea pig jejunal segments. Partial obstruction and sham operations were surgically created in mid-jejunum of male guinea pigs. The animals survived 2, 4, 7 and 14 days. Animals not being operated on served as normal controls. The segments were used for no-load state, zero-stress state and distension analyses. The segment was inflated to 10 cmH(2)O pressure in an organ bath containing 37°C Krebs solution and the outer diameter change was monitored. The stress and strain at the contraction threshold and at maximum contraction were computed from the diameter, pressure and the zero-stress state data. Young's modulus was determined at the contraction threshold. The muscle layer thickness in obstructed intestinal segments increased up to 300%. Compared with sham-obstructed and normal groups, the contraction stress threshold, the maximum contraction stress and the Young's modulus at the contraction threshold increased whereas the strain threshold and maximum contraction strain decreased after 7 days obstruction (P<0.05 and 0.01). In conclusion, in the partially obstructed intestinal segments, a larger distension force was needed to evoke contraction likely due to tissue remodeling. Higher contraction stresses were produced and the contraction deformation (strain) became smaller.

    The nose and the nasal airway is highly complex with intricate 3-dimensional anatomy, with multiple functions in respiration and filtration of the respired air. Nasal airway obstruction (NAO) is a complex problem with no clearly defined "gold-standard" in measurement. There are 3 tools for the measurement of NAO: patient-derived measurements, physician-observed measurements, and objective measurements. We continue to work towards finding a link between subjective and objective nasal obstruction. The field of evaluation and surgical treatment for NAO has grown tremendously in the past 4-5 decades and will continue to grow as we learn more about the pathophysiology and treatment of nasal obstruction.

    To evaluate the efficacy, risks, and survival after palliative colorectal stenting at a single center, we conducted a retrospective review of consecutive patients who had colorectal self-expanding metal stents (SEMSs) inserted over an 8-year period (September 1998 to September 2006) to relieve an obstructing colorectal tumor. All patients either had proven distant metastases or were unfit for surgical decompression. A single interventional radiologist (R.M.) inserted the stents, which were either Memotherm or WallFlex. Ninety-one patients with a median age of 73 years had a colorectal stent inserted for palliation of an obstructing colorectal malignancy. Technical success was achieved in 81 of 91 (89%) patients, and clinical success in 80 of 81 (99%). At the time of analysis (December 2006), 13 of 91 (14.2%) patients were alive. The patients who died had a median survival of 59 days, IQR 17-181 days. Seven (7/81) patients suffered stent migration, which occurred 10.3 days (IQR, 5-14 days) after the procedure. Three patients (3/81) re-presented with intestinal obstruction secondary to tumor ingrowth and 10 (10.9%) patients suffered bowel perforation. Ten patients (10.9%) had two stents inserted coaxially and overlapping in one procedure. This was performed in cases where the stricture was too long to be easily crossed by a single stent. We conclude that colorectal SEMS is a safe and effective mode of treatment for the palliation of obstructing colorectal cancers, which avoids high-risk surgery.

    Abstract Vesicoureteral reflux (VUR) is diagnosed in ∼1% of children. The main goal of treatment is preservation of renal function by preventing recurrent urinary tract infection (UTI) refractory to antibiotic therapy. Surgical treatment options include endoscopic injection or ureteral reimplantation. Subureteral Teflon (polytetrafluoroethylene) injection (STING) is an endoscopic treatment option no longer in common practice. Use of Teflon is no longer advised because of a number of documented complications secondary to local and distant migration of injected material. We present a case of delayed ureteral obstruction secondary to the STING procedure occurring 21 years after initial surgery and managed using a novel endoscopic method. PMID:27785466

    Although many treatments have been proposed for the prevention of intestinal adhesions, none has been completely effective. For bowel obstruction due to adhesions the initial approach should be conservative. If operation becomes necessary, the best results depend on avoidance of trauma and infection, division of adhesions with cautery, use of mesothelial grafts, instillation of intraperitoneal hyaluronidase and stimulation of early postoperative peristalsis. In the event of massive adhesions or failure of other treatment, intestinal plication is the treatment of choice. PMID:18732305

    2017-01-01

    Myeloid sarcoma is an extramedullary collection of blasts of the myeloid series that partially or totally effaces the architecture of the tissue in which it is found. These tumors have been described in many sites of the body, but the skin, lymph nodes, gastrointestinal tract, bone, soft tissue, and testes are most common. They can arise in a patient following the diagnosis of acute myeloid leukemia, but they may also be precursors of leukemia and should be considered diagnostic for acute myeloid leukemia. The differential diagnosis of this neoplasm includes malignant lymphoma, with which it is often mistaken, leading to diagnostic and therapeutic delays. We present the case of an 84-year-old African American man with a history of renal disease secondary to hypertension and coronary artery disease without any prior history of malignancies who presented with airway obstruction. He was diagnosed with a myeloid sarcoma of the mediastinum compressing his trachea.

    PurposeDifferent techniques have been described for stenting of venous obstructions. We report our experience with two different confluence stenting techniques to treat chronic bi-iliocaval obstructions.Materials and MethodsBetween 11/2009 and 08/2014 we treated 40 patients for chronic total bi-iliocaval obstructions. Pre-operative magnetic resonance venography showed bilateral extensive post-thrombotic scarring in common and external iliac veins as well as obstruction of the inferior vena cava (IVC). Stenting of the IVC was performed with large self-expandable stents down to the level of the iliocaval confluence. To bridge the confluence, either self-expandable stents were placed inside the IVC stent (24 patients, SECS group) or high radial force balloon-expandable stents were placed at the same level (16 patients, BECS group). In both cases, bilateral iliac extensions were performed using nitinol stents.ResultsRecanalization was achieved for all patients. In 15 (38 %) patients, a hybrid procedure with endophlebectomy and arteriovenous fistula creation needed to be performed because of significant involvement of inflow vessels below the inguinal ligament. Mean follow-up was 443 ± 438 days (range 7–1683 days). For all patients, primary, assisted-primary, and secondary patency rate at 36 months were 70, 73, and 78 %, respectively. Twelve-month patency rates in the SECS group were 85, 85, and 95 % for primary, assisted-primary, and secondary patency. In the BECS group, primary patency was 100 % during a mean follow-up period of 134 ± 118 (range 29–337) days.ConclusionStenting of chronic bi-iliocaval obstruction shows relatively high patency rates at medium follow-up. Short-term patency seems to favor confluence stenting with balloon-expandable stents.

    Secondary hypertension occurs in a significant proportion of adult patients (~10%). In young patients, renal causes (glomerulonephritis) and coarctation of the aorta should be considered. In older patients, primary aldosteronism, obstructive sleep apnoea and renal artery stenosis are more prevalent than previously thought. Primary aldosteronism can be screened by taking morning aldosterone and renin levels, and should be considered in patients with severe, resistant or hypokalaemia-associated hypertension. Symptoms of obstructive sleep apnoea should be sought. Worsening of renal function after starting an angiotensin-converting enzyme inhibitor suggests the possibility of renal artery stenosis. Recognition, diagnosis and treatment of secondary causes of hypertension lead to good clinical outcomes and the possible reversal of end-organ damage, in addition to blood pressure control. As most patients with hypertension are managed at the primary care level, it is important for primary care physicians to recognise these conditions and refer patients appropriately. PMID:27211205

    The human body normally lives in symbiosis with a considerable microscopic environment present on all interfaces with the external environment; it hosts ten times more microbes (microbiota) that it has somatic or germ cells, representing a gene diversity (microbiome) 100-150 times higher than the human genome. These germs are located mainly in the gut, where they represent a mass of about one kilogram. The primary colonization of the gastrointestinal tract depends on the delivery route, the bacterial flora rewarding then depending on the environment, food hygiene, medical treatments. The intestinal microbiota plays an important role in the maturation of the immune system and in different physiological functions: digestion of polysaccharides, glycosaminoglycans and glycoproteins, vitamins biosynthesis, bile salt metabolism of some amino acids and xenobiotics. Quantitative and qualitative changes in the microbiota are observed in a wide range of diseases: obesity, colorectal cancer, liver cancer, inflammatory bowel disease, autoimmune diseases, allergies... pharmacobiotics aim to modify the intestinal microbiota in a therapeutic goal and this by various means: prebiotics, probiotics, antibiotics or fecal transplants. Intestinal flora also plays a direct role in the metabolism of certain drugs and the microbiota should be considered as a predictive parameter of response to some chemotherapies.

    Intestinal obstruction due to a phytobezoar within a Meckel diverticulum is exceedingly rare, with only seven reported cases in the surgical literature. The most important precipitating factor is the ingestion of agents high in fiber and cellulose. Small bowel obstruction in all but one case was due to retrograde propagation of the bezoar into the small bowel lumen. We report the clinical and CT findings in such a patient following a vegetarian diet. 14 refs., 2 figs.

    Megacystis-microcolon-intestinal hypoperistalsis syndrome is a multisystemic disorder in which impaired intestinal motor activity causes recurrent symptoms of intestinal obstruction in the absence of mechanical occlusion, associated with bladder distention without distal obstruction of the urinary tract. It is an uncommon disorder with high morbidity and mortality, and long-term total parenteral nutrition may be required. We describe an 18-year-old girl with long-term survival, followed-up by our service since birth. With medical, surgical and nutritional management she currently presents a good oral tolerance and good quality of life, only requiring parenteral nutrition during periods of decompensation.

    Purpose. The purpose of this study was to retrospectively evaluate interventional radiological management of patients with symptomatic portal hypertension secondary to obstruction of splanchnic veins. Material and Methods. Twenty-four patients, 15 males and 9 females, 0.75 to 79 years old (mean, 36.4 years), with symptomatic portal hypertension, secondary to splanchnic venous obstruction, were treated by percutaneous methods. Causes and extent of splanchnic venous obstruction and methods are summarized following a retrospective evaluation. Results. Obstructions were localized to the main portal vein (n = 22), intrahepatic portal veins (n = 8), splenic vein (n = 4), and/or mesenteric veins (n = 4). Interventional treatment of 22 (92%) patients included recanalization (n = 19), pharmacological thrombolysis (n = 1), and mechanical thrombectomy (n = 5). Partial embolization of the spleen was done in five patients, in two of them as the only possible treatment. TIPS placement was necessary in 10 patients, while an existing occluded TIPS was revised in two patients. Transhepatic embolization of varices was performed in one patient, and transfemoral embolization of splenorenal shunt was performed in another. Thirty-day mortality was 13.6% (n=3). During the follow-up, ranging between 2 days and 58 months, revision was necessary in five patients. An immediate improvement of presenting symptoms was achieved in 20 patients (83%). Conclusion. We conclude that interventional procedures can be successfully performed in the majority of patients with obstruction of splanchnic veins, with subsequent improvement of symptoms. Treatment should be customized according to the site and nature of obstruction.

    Colonic complications are rare after acute pancreatitis but are associated with a high mortality. Possible complications include mechanical obstruction, ischaemic necrosis, haemorrhage, and fistula. We report a case of large bowel obstruction in a 31-year-old postpartum female, secondary to severe gallstone pancreatitis. The patient required emergency laparotomy and segmental bowel resection, as well as cholecystectomy. Presentation of obstruction occurs during the acute episode or can be delayed for several weeks. The most common site is the splenic flexure owing to its proximity to the pancreas. Initial management may be conservative, stenting, or surgical. CT is an acceptable baseline investigation in all cases of new onset bowel obstruction. Although bowel obstruction is a rare complication of pancreatitis, clinicians should be aware of it due to its high mortality. Obstruction can occur after a significant delay following the resolution of pancreatitis. Those patients with evidence of colonic involvement on pancreatic imaging warrant further large bowel evaluation. Bowel resection may be required electively or acutely. Colonic stenting has an increasing role in the management of large bowel obstruction but is a modality of treatment that needs further evaluation in this setting. PMID:27847668

    Abstract Objective: To describe the case of an infant with Hirschsprung's disease presenting as total colonic aganglionosis, which, after surgical resection of the aganglionic segment persisted with irreversible functional intestinal obstruction; discuss the difficulties in managing this form of congenital aganglionosis and discuss a plausible pathogenetic mechanism for this case. Case description: The diagnosis of Hirschsprung's disease presenting as total colonic aganglionosis was established in a two-month-old infant, after an episode of enterocolitis, hypovolemic shock and severe malnutrition. After colonic resection, the patient did not recover intestinal motor function that would allow enteral feeding. Postoperative examination of remnant ileum showed the presence of ganglionic plexus and a reduced number of interstitial cells of Cajal in the proximal bowel segments. At 12 months, the patient remains dependent on total parenteral nutrition. Comments: Hirschsprung's disease presenting as total colonic aganglionosis has clinical and surgical characteristics that differentiate it from the classic forms, complicating the diagnosis and the clinical and surgical management. The postoperative course may be associated with permanent morbidity due to intestinal dysmotility. The numerical reduction or alteration of neural connections in the interstitial cells of Cajal may represent a possible physiopathological basis for the condition. PMID:26979103

    Enteric intussusception caused by primary intestinal malignant melanoma is a very rare cause of intestinal obstruction. We herein present a case of a 42-year-old female patient with no prior medical history of malignant melanoma, who was admitted with persistent abdominal pain, nausea, and vomiting. A computed tomography scan revealed an intestinal obstruction due to ileocolic intussusception. An emergency laparoscopy and subsequent laparotomy revealed multiple small solid tumors across the whole small bowel. An oncologic resection was not feasible due to the insufficient length of the remaining small bowel. Only a small segment of ileum, which included the largest tumors causing the intussusception, was resected. The pathologic examination revealed two intestinal malignant melanoma lesions. A systematic clinical examination, endoscopic procedures, and fluorodeoxyglucose positron emission tomography-computed tomography scan all failed to reveal any indication of cutaneous, anal, or retinal melanoma. Hence, the tumor was classified as a primary intestinal malignant melanoma with multiple intestinal metastases. Since a complete oncologic resection of tumors was not possible, in order to prevent future intestinal obstruction, a surgical resection of the largest lesions was performed with palliative intention. The epidemiology, clinical manifestations, diagnosis and management of primary intestinal malignant melanoma, and intestinal intussusception in adults are discussed along with a review of the current literature.

    Objective Benign nodular goiter (BNG) can cause narrowing of the upper airway. In some rare cases, obstruction of the upper airway also occurs. The following paper reports our experiences with regard to BNG patients who experienced obstruction of the upper airway. Materials and Methods. We retrospectively investigated the records of 13 patients with acute airway obstruction due to BNG who were admitted to the General Surgery Department of Ataturk University Medical School between January 2000 and December 2007. Results Thirteen patients with airway obstruction secondary to BNG were hospitalized during this period. There were two males and 11 females, and the mean age was 58.5 years (range 37–74 years). For all patients, the primary symptom upon admission was defined as respiratory distress; all patients had varying degrees of respiratory distress upon admission. Three of the patients underwent emergent endotracheal intubation in the emergency room. A preoperative radiological evaluation was performed with thyroid ultrasonography (US) and computed tomography (CT). There were retrosternal or substernal components of the BNG in nine patients. Twelve patients underwent operations, while one patient with mild respiratory distress elected not to be operated on. Ten patients underwent total thyroidectomies, while two patients underwent near-total thyroidectomies. One patient with retrosternal goiter also underwent a median sternotomy. Three patients received a tracheostomy after the operation. Suction drains were utilized in all operations. During the post-operative period, two patients suffered from voice impairment, and seven patients experienced hypocalcemia. Two patients died. Pathological examination of the thyroidectomy tissue revealed BNG in all cases. In addition, two patients had micropapillary carcinomas. Conclusion Although BNG causing upper airway obstruction is rare, it is an important clinical entity because of the need for emergent operation, the

    Intestinal capillariasis caused by Capillaria philippinensis appeared first in the Philippines and subsequently in Thailand, Japan, Iran, Egypt, and Taiwan, but most infections occur in the Philippines and Thailand. As established experimentally, the life cycle involves freshwater fish as intermediate hosts and fish-eating birds as definitive hosts. Embryonated eggs from feces fed to fish hatch and grow as larvae in the fish intestines. Infective larvae fed to monkeys, Mongolian gerbils, and fish-eating birds develop into adults. Larvae become adults in 10 to 11 days, and the first-generation females produce larvae. These larvae develop into males and egg-producing female worms. Eggs pass with the feces, reach water, embryonate, and infect fish. Autoinfection is part of the life cycle and leads to hyperinfection. Humans acquire the infection by eating small freshwater fish raw. The parasite multiplies, and symptoms of diarrhea, borborygmus, abdominal pain, and edema develop. Chronic infections lead to malabsorption and hence to protein and electrolyte loss, and death results from irreversible effects of the infection. Treatment consists of electrolyte replacement and administration of an antidiarrheal agent and mebendazole or albendazole. Capillariasis philippinensis is considered a zoonotic disease of migratory fish-eating birds. The eggs are disseminated along flyways and infect the fish, and when fish are eaten raw, the disease develops. Images PMID:1576584

    Crohn's disease (CD) is an autoimmune disease, which may cause obstructing intestinal strictures due to inflammation, fibrosis (deposition of collagen), or a combination of both. Identifying the different stages of the disease progression is still challenging. In this work, we indicated the feasibility of non-invasively characterizing intestinal strictures using photoacoustic imaging (PAI), utilizing the uniquely optical absorption of hemoglobin and collagen. Surgically removed human intestinal stricture specimens were investigated with a prototype PAI system. 2D PA images with acoustic resolution at wavelength 532, 1210 and 1310 nm were formulated, and furthermore, the PA histochemical components images which show the microscopic distributions of histochemical components were solved. Imaging experiments on surgically removed human intestinal specimens has demonstrated the solved PA images were significantly different associated with the presence of fibrosis, which could be applied to characterize the intestinal strictures for given specimens.

    Prenatal ultrasound has led to confidence in the antenatal diagnosis of intestinal obstruction allowing counseling and birth planning. We describe a male infant of a diabetic mother who had an antenatal diagnosis of distal bowel obstruction. This baby was subsequently found not to have bowel obstruction, but a congenital enteropathy - microvillous inclusion disease. The antenatal scans had demonstrated polyhydramnios as well as multiple fluid-filled dilated loops of bowel in the fetal abdomen. To our knowledge, similar prenatal ultrasound findings have not been previously described in this condition. The baby was delivered in a pediatric surgical center and postnatally there was no evidence of bowel obstruction either clinically or on abdominal X-ray. This baby initially fed well, but became collapsed and acidotic on his third day, having lost 26% of his birth weight due to excessive stool loss. The diagnosis of microvillous inclusion disease was made by electron microscopy of a small bowel biopsy. Congenital microvillous inclusion disease is a very rare inherited enteropathy with high mortality and morbidity. This condition, and other enteropathies, should be considered in cases in which antenatally diagnosed bowel obstruction is not confirmed after birth.

    Giardia is the best known cause of protozoal gastrointestinal disease in North America, producing significant but not life-threatening gastrointestinal distress and diarrhea. Although diagnosis of giardiasis may be challenging, treatment is usually successful. Entamoeba histolytica poses a rarer but far more difficult clinical challenge. Dysentery caused by E. histolytica may be the most feared intestinal protozoal infection, although Cryptosporidium parvum, Balantidium coli, Isospora belli, Sarcocystis species and other newly described protozoa also may cause diarrhea in healthy individuals and may result in intractable, life-threatening illness in patients with acquired immunodeficiency syndrome or other immunosuppressive diseases. Certain protozoa once considered relatively unimportant, such as Cryptosporidium, are now recognized as significant causes of morbidity even in the United States, since transmission readily occurs through contaminated water.

    Острая тонкокишечная непроходимость (ОТКН) является распространенным заболеванием, возникающим вследствие механической или функциональной обструкции тонкой кишки и препятствующим нормальному пассажу ее содержимого. Пациенты с ОТКН составляют, по данным современной литературы, до 20% всех хирургических больных, поступающих в стационары с острой болью в животе. Послеоперационная летальность при острой кишечной непроходимости составляет от 6,7 до 36,2% при общей летальности от 2,5 до 15,8%. Клиническая практика показывает, что у пациентов с ОТКН в динамике развития заболевания и в послеоперационном периоде, после ее устранения, острые изъязвления гастродуоденальной зоны встречаются весьма часто (до 50% наблюдений). В 1—5% наблюдений острые изъязвления гастродуоденальной зоны желудочно-кишечного тракта сопровождаются перфорацией стенки желудка или двенадцатиперстной кишки, у 20—25% больных — гастродуоденальными кровотечениями, обусловливают летальность 35—80%. Даже при отсутствии осложнений острые эрозии и язвы желудка значительно утяжеляют состояние больных, повышают риск развития других осложнений, продлевают срок нахождения больного в стационаре. Цель работы — выявление закономерностей морфофункциональных изменений в стенках желудка в динамике развития различных видов ОТКН. Изучить морфофункциональные изменения в стенках желудка на клиническом материале, выполняя биопсию в динамике развития заболевания, не представляется возможным, поэтому основой нашей работы стало экспериментальное моделирование различных видов ОТКН.

Все научные исследования проведены в соответствии с руководящими документами, такими как «Руководство по уходу и использованию лабораторных животных Национального института здравоохранения (National Institute of Health — NIH, Бетесда, США)» и «Правила проведения работ с экспериментальными животными». Методы исследования морфологии стенок желудка в норме и после моделирования тонкокишечной непроходимости применяли одни и те же. Использовали окраску гематоксилином и эозином, пикрофуксином по Ван-Гизону в сочетании с окраской по Маллори, гистохимические методики изучения обменных процессов в клетках эпителия и желез слизистой оболочки желудка, метод Эйнарсона для выявления суммарных нуклеиновых кислот. Последнюю группу методов составил статистический анализ полученных данных. Результаты. Выявлены закономерности организации гемомикроциркуляторного русла (ГМЦР) в различных отделах желудка, морфофункциональные изменения в стенках желудка в динамике развития различных видов острой тонкокишечной непроходимости. Вывод. Полученные нами данные указывают на наличие проксимодистального градиента желудочной перфузии: наиболее выраженная сосудистая сеть и, следовательно, максимальный кровоток как в норме, так и в динамике развития ОТКН выявляются в проксимальных отделах желудка и более разреженная, с редуцированным кровотоком — в антральном отделе, что служит морфологической основой наиболее частой локализации острых язв именно в этом отделе. Изменения в сосудистых сплетениях и в ГМЦР слизистой оболочки и подслизистой основы желудка при ОТКН сопровождаются отеком собственной пластинки и подслизистой основы слизистой оболочки, наиболее выраженным в антральном отделе желудка, что является фактором, способствующим последующей компрессии сосудов ГМЦР и прогрессивному нарушению перфузии тканей. Уменьшение интенсивности капиллярного кровотока снижает метаболическую активность клеток покровно-эпителиального пласта и их способность противостоять дестабилизации защитного барьера. При этом наиболее значимо угнетаются обменные процессы в клетках шеечной части и дна желез, являющихся камбиальной, ростковой зоной, что обусловливает снижение репаративных возможностей слизистой оболочки желудка. Метаболические расстройства являются следствием нарушений гемодинамики, они вызываются и затем поддерживаются тканевой гипоксией, способствующей в свою очередь прогрессированию нарушений гемодинамики.

    Intestinal or cloacal strictures that resulted in intestinal obstruction were diagnosed in six green sea turtles (Chelonia mydas) from three rehabilitation facilities and two zoologic parks. The etiologies of the strictures were unknown in these cases. It is likely that anatomic adaptations of the gastrointestinal tract unique to the green sea turtle's herbivorous diet, paired with causes of reduced intestinal motility, may predispose the species to intestinal damage and subsequent obstructive intestinal disease. In aquarium-maintained green sea turtles, obesity, diet, reduced physical activity, chronic intestinal disease, and inappropriate or inadequate antibiotics might also be potential contributing factors. Clinical, radiographic, and hematologic abnormalities common among most of these sea turtles include the following: positive buoyancy; lethargy; inappetence; regurgitation; obstipation; dilated bowel and accumulation of oral contrast material; anemia; hypoglycemia; hypoalbuminemia; hypocalcemia; and elevated creatine kinase, aspartate aminotransferase, and blood urea nitrogen. Although these abnormalities are nonspecific with many possible contributing factors, intestinal disease, including strictures, should be considered a differential in green sea turtles that demonstrate all or a combination of these clinical findings. Although diagnostic imaging, including radiographs, computed tomography, or magnetic resonance imaging, are important in determining a cause for suspected gastrointestinal disease and identifying an anatomic location of obstruction, intestinal strictures were not successfully identified when using these imaging modalities. Lower gastrointestinal contrast radiography, paired with the use of oral contrast, was useful in identifying the suspected site of intestinal obstruction in two cases. Colonoscopy was instrumental in visually diagnosing intestinal stricture in one case. Therefore, lower gastrointestinal contrast radiography and

    Chilaiditi's sign and syndrome seem similar but are actually different entities, difficult to distinguish from each other. A 60-year-old female presented with a clinical scenario of intestinal obstruction, which was thought to be Chilaiditi's syndrome because of the unusual impression of gas under the diaphragm, but was confirmed as Chilaiditi's sign after laparotomy. The interposition of dilated small bowel loops below the diaphragm due to distal obstruction somewhere else can also produce a Chilaiditi's sign. PMID:26270528

    Obstructive sleep apnoea is an increasingly common disorder of repeated upper airway collapse during sleep, which leads to oxygen desaturation and disrupted sleep. Symptoms include snoring, witnessed apnoeas, and sleepiness. Pathogenesis varies; predisposing factors include small upper airway lumen, unstable respiratory control, low arousal threshold, small lung volume, and dysfunctional upper airway dilator muscles. Risk factors include obesity, male sex, age, menopause, fluid retention, adenotonsillar hypertrophy, and smoking. Obstructive sleep apnoea causes sleepiness, road traffic accidents, and probably systemic hypertension. It has also been linked to myocardial infarction, congestive heart failure, stroke, and diabetes mellitus though not definitively. Continuous positive airway pressure is the treatment of choice, with adherence of 60–70%. Bi-level positive airway pressure or adaptive servo-ventilation can be used for patients who are intolerant to continuous positive airway pressure. Other treatments include dental devices, surgery, and weight loss. PMID:23910433

Several pathogenetic factors (functional, anatomical, neurological, genetical) are still being discussed. However new insights of the pathophysiology of apneas allow more reliable treatments. Central nervous and cardiovascular complications as well as the traumatic morbidity, associated with excessive daytime sleepiness, make it a major public health problem.

    The techniques that have come into general use for diagnosing problems of obstructive jaundice, particularly in the past ten years, have been ultrasonography, computerized tomography, radionuclide imaging, transhepatic percutaneous cholangiography using a long thin needle, transhepatic percutaneous drainage for obstructive jaundice due to malignancy, endoscopic retrograde cannulation of the papilla (ERCP), endoscopic sphincterotomy and choledochoscopy. It is helpful to review obstructive jaundice due to gallstones from a clinical point of view and the use of the directable stone basket for the retrieval of retained stones, choledochoscopy for the same purpose using the rigid versus flexible choledochoscopes and dissolution of stones using various fluids through a T tube. The use of dilation of the sphincter for the treatment of stenosis or stricture of the bile duct is now frowned on; rather, treatment choices are between the use of sphincteroplasty versus choledochoduodenostomy and choledochojejunostomy. Any patient with obstructive jaundice or anyone undergoing manipulation of the bile ducts should have prophylactic antibiotic therapy. The current literature regarding treatment of cancer of the bile ducts is principally devoted to the new ideas relative to treatment of tumors of the upper third, especially the bifurcation tumors that are now being resected rather than bypassed. Tumors of the distal bile duct are still being resected by focal operations. Finally, it is now felt that early operation for congenital biliary atresia and choledochal cysts gives the best prognosis, with preoperative diagnosis now possible with the use of ultrasonography and ERCP.

    Acute and chronic renal failure secondary to bilateral severe hydroureteronephrosis is a rare sequela of uterine prolapse. We report a case of neglected complete uterine prolapse in a 72-year-old patient resulting in bilateral hydroureter, hydronephrosis, and chronic renal failure. In an attempt to diminish the ureteral obstruction a vaginal pessary was used to reduce the uterine prolapse. Finally, surgical repair of prolapse by means of a vaginal hysterectomy was performed. In conclusion, all patients presenting with complete uterine prolapse should be screened to exclude urinary tract obstruction. If present, obstructive uropathy should be relieved by the reduction or repair of the prolapse before irreversible renal damage occurs.

  10. Airflow obstruction and exercise.

    PubMed

    Cooper, Christopher B

    2009-03-01

    The primary abnormality in chronic obstructive pulmonary disease (COPD) is chronic airway inflammation which results in airflow limitation. Disease progression is usually depicted as an accelerated decline in FEV(1) over time. However, COPD patients also manifest progressive static hyperinflation due to the combined effects of reduced lung elastic recoil and increased airway resistance. Superimposed on static hyperinflation are further increases in operational lung volumes (dynamic hyperinflation) brought on during exercise, exacerbations or tachypnea. An important consequence of exertional dyspnea is activity limitation. COPD patients have been shown to spend only a third of the day walking or standing compared with age-matched healthy individuals who spend more than half of their time in these activities. Furthermore, the degree of activity limitation measured by an accelerometer worsens with disease progression. COPD patients have been shown to have an accelerated loss of aerobic capacity (VO(2)max) and this correlates with mortality just as is seen with hypertension, diabetes and obesity. Thus physical inactivity is an important therapeutic target in COPD. Summarizing; airflow obstruction leads to progressive hyperinflation, activity limitation, physical deconditioning and other comorbidities that characterize the COPD phenotype. Targeting the airflow obstruction with long-acting bronchodilator therapy in conjunction with a supervised exercise prescription is currently the most effective therapeutic intervention in earlier COPD. Other important manifestations of skeletal muscle dysfunction include muscle atrophy and weakness. These specific problems are best addressed with resistance training with consideration of anabolic supplementation.

    There is accumulative evidence on the multiple functions of the intestinal microflora in relation to the homeostasis of the host. At first considered as a simple mutualism, today this relationship proves to be essential to the health and to pathologic processes, particularly metabolic (eg, obesity) and gastrointestinal (eg, inflammatory bowel disease and functional disorders). The first studies were conducted on the microbiota from fecal material cultured anaerobically. With the advent of molecular biology, it has become possible to determine qualitative and quantitatively the dominant, subdominant and transients species. In recent years, there were advances in the understanding of the relationship betwen the microbiota and the host, as well as among the microorganisms in their respective niches. These advances result from translational integration of microbiology with specialities such as molecular biology, cell phisiology, immunology and ecology. There are few studies on the spatial distribution of the microflora in the gut. Unravelling the topography of the microflora in mammals is a way to validate new animal models for the study of microflora.

To date, only 4 cases of neuroblastoma causing obstructive jaundice at diagnosis have been reported in children. We report a 4-year-old boy who presented to the emergency department with abdominal pain, jaundice, choluria and acholia. A diagnosis of unresectable, nonmetastatic neuroblastoma was made. Chemotherapy reduced the size of the tumor and relieved the symptoms of obstructive jaundice without the need for decompressive surgery. Abdominal tumors should be included in the differential diagnoses of obstructive jaundice in childhood.

    Systemic lupus erythematosus (SLE) is a systemic autoimmune inflammatory disease, which can affect almost all systems and organs. Gastrointestinal disorder is one of the most noteworthy complications of patients with SLE. However, gastrointestinal disorder with intestinal perforation is rare, but potentially life-threatening if not treated promptly. The present study reported a case of SLE with intestinal perforation, where surgical intervention was performed and a crevasse (~3 cm in diameter) was detected in the ileum, ~60 cm from the ileocecal valve. Following surgery, the patient suffered from difficult ventilator weaning, septic shock and intestinal obstruction. The patient was successfully treated and discharged from the hospital after ~4 months of treatment. Intestinal perforation in SLE patients is potentially life-threatening; early diagnosis and prompt treatment are crucial to the management of this rare complication of SLE. PMID:26622471

    Urinary tract obstruction (UTO) is a frequent cause of renal failure in the pediatric population. We report a patient with type I/I cystinuria, followed prospectively from birth with yearly ultrasonography, who developed acute UTO due to a cystine stone at 10 years of age. In animal models of UTO, acute obstruction produces rapid loss of renal parenchyma secondary to apoptosis of tubular cells. Since we had prospectively obtained serial ultrasonographic measurements of renal growth, we were able to document sudden decrease in kidney size and function following UTO, suggesting that programmed cell death may similarly have caused the rapid irreversible loss of renal parenchyma in our patient. Despite surgical relief of the obstruction, kidney size decreased for at least 3-4 months. We speculate that anti-apoptotic drugs might be considered as a therapeutic strategy to protect ongoing renal parenchyma loss in UTO.

    Obstruction of salivary glands occurs in association with a number of pathological conditions. It has been suggested that the major changes found in the salivary glands of patients with cystic fibrosis are due to obstruction of the excretory duct by viscous mucus. In the present study, the effect of excretory duct obstruction on structure, elemental composition and function of rat submandibular gland was investigated. Obstruction was effected by infusion of a fast-hardening protein emulsion in the main excretory duct. After 1 week, and more pronounced after 2 weeks of obstruction the number of granular duct cells had decreased in the obstructed gland. X-ray microanalysis showed an increase in Mg, Ca and K, and a decrease in Na levels in the acinar cells, compared to normal glands. The contralateral glands apparently underwent compensatory hypertrophy and showed a similar pattern of changes in elemental composition. The composition of pilocarpine-induced submandibular saliva was neither in the obstructed nor in the contralateral gland significantly different from that in control glands. However, the flow rate was somewhat lower. Hence, increase in cellular Ca levels in submandibular gland acinar cells in cystic fibrosis could be secondary to duct obstruction, but the present study does not support the hypothesis that duct obstruction would result in changes in the composition of saliva.

    Total parenteral nutrition now permits long-term survival in patients after massive intestinal resection. Surgical therapy for the short-bowel syndrome is still largely experimental and cannot be recommended routinely. Thus, prevention of intestinal resection and conservation of intestinal length, when resection is necessary, should be emphasized. Strategies are presented that can be employed to preserve intestinal length when surgery is required in patients with a shortened bowel. These include strictureplasty, minimal resection, serosal patching, and intestinal tapering. In suitable candidates strictureplasty can relieve obstruction from strictures while avoiding resection. Minimal resection of involved intestine can be performed safely in selected patients with radiation injury or Crohn's disease. Serosal patching is an alternative to resection for the treatment of perforation or strictures of the intestine. Intestinal tapering can improve the function of dilated intestinal segments and eliminate the need for resection in intestinal atresia. The judicious use of these procedures can preserve intestinal length and obviate the need for long-term parenteral nutrition in patients after massive intestinal resection.

    Sarcoidosis is a systemic granulomatous disease of unknown etiology, characterized by the formation of noncaseating granulomas. Gastrointestinal (GI) system involvement that is clinically recognizable occurs in less than 0.9% of patients with sarcoidosis, with data revealing small intestine involvement in 0.03% of the cases. A high index of suspension is required in patients presenting with small-bowel obstruction and previous history of sarcoidosis. Establishing a definitive diagnosis of GI sarcoidosis depends on biopsy evidence of noncaseating granulomas, exclusion of other causes of granulomatous disease, and evidence of sarcoidosis in at least one other organ system. Treatment of GI sarcoidosis depends on symptomatology and disease activity. Herein, we are presenting a case of 67-year-old female patient who had acute small-bowel obstruction at the level of jejunum with postoperative histopathologic evidence of noncaseating granulomatous inflammation with multinucleated giant cells, consistent with sarcoidosis.

    The obstructive sleep apnea syndrome (OSAS) is caused by an intermittent and repetitive obstruction of the upper respiratory tract during sleep, which leads to a complete (apnea) or partial (hypopnea) block of air flow. It is quite prevalent, being seen in 4-6% of males and 2% of females. Structural abnormalities present in the upper respiratory tract and obesity are the fundamental etiological factors. Clinical manifestations are due to sleep fragmentation and oxygen desaturation which cause the apnea. Day hypersomnia, snoring and episodes of apnea described by the spouse are the three basic symptoms. The diagnosis is based on polysomnography, which can be substituted for a night cardiorespiratory polygraphy. It has an important morbimortality rate, mainly due to traffic and labor accidents, ischemic heart disease and chronic respiratory failure. The treatment is multifactorial. First, eliminating alcohol and hypnotic drugs. Obesity, which is almost always present, must also be corrected. Structural abnormalities of the upper respiratory tract may require a surgical solution. The treatment preferred nowadays is the application of a nasal continuous positive airway pressure (CPAP) while the patient is asleep. It should be considered for those symptomatic patients with an apnea-hypopnea index over 30, or if the index is below 30, than when a respiratory insufficiency or cardiovascular risk factors are present. In some cases surgical procedures may be considered, such as uvulopalatopharyngoplasty.

    Background Circadian rhythm disruption is a prevalent feature of modern day society that is associated with an increase in pro-inflammatory diseases and there is a clear need for a better understanding of the mechanism(s) underlying this phenomenon. We have previously demonstrated that both environmental and genetic circadian rhythm disruption causes intestinal hyperpermeability and exacerbates alcohol-induced intestinal hyperpermeability and liver pathology. The intestinal microbiota can influence intestinal barrier integrity and impact immune system function; thus, in the current study, we sought to determine if genetic alteration of the core circadian clock gene, Clock, altered the intestinal microbiota community. Methods Male ClockΔ19 mutant mice (mice homozygous for a dominant-negative mutant allele) or littermate wild-type mice were fed one of three experimental diets: (1) a standard chow diet, (2) an alcohol-containing diet, or (3) an alcohol-control diet in which the alcohol calories were replaced with dextrose. Stool microbiota was assessed with 16S ribosomal RNA gene amplicon sequencing. Results The fecal microbial community of Clock mutant mice had lower taxonomic diversity, relative to wild type mice and the ClockΔ19 mutation was associated with intestinal dysbiosis when mice were fed either the alcohol-containing or the control diet. We found that alcohol consumption significantly altered the intestinal microbiota in both wild type and Clock mutant mice. Conclusion Our data support a model by which circadian rhythm disruption by the ClockΔ19 mutation perturbs normal intestinal microbial communities and this trend was exacerbated in the context of a secondary dietary intestinal stressor.

    Malignant obstruction develops frequently in advanced gastric cancer. Although it is primarily the gastric outlet that is obstructed, there are occasional reports of colonic obstruction. Treating intestinal obstruction usually requires emergency surgery or stent insertion. There are several kinds of complications with stent insertion, such as bowel perforation, stent migration, bleeding, abdominal pain and reobstruction. Nevertheless, endoscopic stent insertion could be a better treatment than emergency surgery in cases of malignant bowel obstruction in cancer patients with poor performance status. We report a case of advanced gastric cancer with carcinomatosis in which a recurrent colonic stent was inserted at the same site because of cancer growth into the stent. The patient maintained a good condition for chemotherapy, thus improving their chances for survival. PMID:19430568

    A 10-year-old DSH cat was referred for a dental evaluation and extraction procedure. Subsequently, the animal developed an acute onset of ocular discharge. Ophthalmologic examination revealed presence of unilateral ocular mucoid discharge leading to a diagnosis of epiphora secondary to nasolacrimal duct obstruction. Dacryocystorhinography was performed and confirmed the presence of a nasolacrimal duct obstruction, presumably acquired after an invasive dental procedure. Additionally, a vinyl cast in situ study of the nasolacrymal apparatus was performed to demonstrate the route of the nasolacrimal duct in the cat and its relationship to oral dental structures. This report documents an unusual case in which excessive inflammation/edema following tooth extraction caused acute epiphora secondary to extraluminal compression of the distal nasolacrimal duct.

    Background Intestinal obstruction is a poorly recognized and probably underreported complication of strongyloidiasis. We present herein an unusual case, of complete duodenal obstruction caused by S. stercoralis. Methods A systematic review of the literature examining the clinical course, diagnostic methods, and outcome of this rare complication of strongyloidiasis was performed. Results A 42-year-old woman presented with a 5-month history of abdominal pain, vomit, and weight loss. An abdominal CT scan showed an obstruction of the third part of the duodenum. Segmental intestinal resection was carried out and histopathology examination revealed heavy Strongyloides stercoralis infestation. Duodenal obstruction is a rare complication of S. stercoralis infection, with only 8 cases described in the literature since 1970. Most of the patients are males, middle-aged, and the diagnosis was made by duodenal aspirate/biopsy, or analysis of surgical specimen. Conclusions Duodenal obstruction is an unusual, but potential fatal, complication of S. stercoralis infection. The large spectrum of clinical manifestation and lack of classic clinical syndrome make the final diagnosis of strongyloidiasis extremely difficult. A high index of suspicion, mainly in patients from endemic areas, is needed for correct and early diagnosis of this uncommon presentation of Strogyloides stercoralis enteritis. PMID:20698992

    Adhesive small bowel obstruction is a frequent cause of hospital admission. Water soluble contrast studies may have diagnostic and therapeutic value and avoid challenging demanding surgical operations, but if bowel ischemia is suspected, prompt surgical intervention is mandatory. A 58-year-old patient was operated for extensive adhesive small bowel obstruction after having had two previous laparotomies for colorectal surgery, and had a complex clinical course with multiple operations and several complications. Different strategies of management have been adopted, including non-operative management with the use of hyperosmolar water soluble contrast medium, multiple surgical procedures, total parenteral nutrition (TPN) support, and finally use of antiadherences icodextrin solution. After 2 years follow-up the patient was doing well without presenting recurrent episodes of adhesive small bowel obstruction. For patients admitted several times for adhesive small bowel obstruction, the relative risk of recurring obstruction increases in relation to the number of prior episodes. Several strategies for non-operative conservative management of adhesive small bowel obstruction have already addressed diagnostic and therapeutic value of hyperosmolar water soluble contrast. According to the most recent evidence-based guidelines, open surgery is the preferred method for surgical treatment of strangulating adhesive small bowel obstruction as well as after failed conservative management. Research interest and clinical evidence are increasing in adhesions prevention. Hyaluronic acid-carboxycellulose membrane and icodextrin may reduce incidence of adhesions.

    Metastatic breast cancer is typically identified in the bones, lymph nodes, lungs and liver. Rarely does metastatic breast cancer involve the common bile duct (CBD) without direct extension from liver metastasis into the CBD. We present a woman diagnosed with metastatic breast cancer in the CBD after presenting with obstructive jaundice. Patients with a history of primary breast cancer who present with obstructive jaundice secondary to CBD mass need identification of the mass in order to provide appropriate treatment. PMID:26351417

    The global prevalence of physiologically defined chronic obstructive pulmonary disease (COPD) in adults aged >40 yr is approximately 9-10 per cent. Recently, the Indian Study on Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis in Adults had shown that the overall prevalence of chronic bronchitis in adults >35 yr is 3.49 per cent. The development of COPD is multifactorial and the risk factors of COPD include genetic and environmental factors. Pathological changes in COPD are observed in central airways, small airways and alveolar space. The proposed pathogenesis of COPD includes proteinase-antiproteinase hypothesis, immunological mechanisms, oxidant-antioxidant balance, systemic inflammation, apoptosis and ineffective repair. Airflow limitation in COPD is defined as a postbronchodilator FEV1 (forced expiratory volume in 1 sec) to FVC (forced vital capacity) ratio <0.70. COPD is characterized by an accelerated decline in FEV1. Co morbidities associated with COPD are cardiovascular disorders (coronary artery disease and chronic heart failure), hypertension, metabolic diseases (diabetes mellitus, metabolic syndrome and obesity), bone disease (osteoporosis and osteopenia), stroke, lung cancer, cachexia, skeletal muscle weakness, anaemia, depression and cognitive decline. The assessment of COPD is required to determine the severity of the disease, its impact on the health status and the risk of future events (e.g., exacerbations, hospital admissions or death) and this is essential to guide therapy. COPD is treated with inhaled bronchodilators, inhaled corticosteroids, oral theophylline and oral phosphodiesterase-4 inhibitor. Non pharmacological treatment of COPD includes smoking cessation, pulmonary rehabilitation and nutritional support. Lung volume reduction surgery and lung transplantation are advised in selected severe patients.

    Research on intestinal bacteria began around the end of the 19th century. During the last 5 decades of the 20th century, research on the intestinal microbiota made rapid progress. At first, in my work, I first developed a method of comprehensive analysis of the intestinal microbiota, and then I established classification and identification methods for intestinal anaerobes. Using these methods I discovered a number of ecological rules governing the intestinal microbiota and the role of the intestinl microbiota in health and disease. Moreover, using germfree animals, it was proven that the intestinal microbiota has a role in carcinogenesis and aging in the host. Thus, a new interdisciplinary field, “intestinal bacteriology” was established. PMID:25032084

    Gastro-duodenal obstruction encompasses a spectrum of benign and malignant disease. Historically, chronic peptic ulcer disease was the main cause of gastro-duodenal obstruction, whereas now malignant cause with gastric carcinomas for gastric obstruction and pancreatic tumors for duodenal obstruction predominate. This paper reviews the role of CT in diagnosing gastro-duodenal obstruction, its level, its cause by identifying intraluminal, parietal, or extrinsic process, and the presence of complication.

    Obstructive sleep apnoea (OSA) correlates positively with obesity and age, both of which are becoming increasingly prevalent. Obstructive sleep apnoea occurs much more frequently in clinical practice than formerly diagnosed, and that this condition represents complex challenges for difficulty in mask ventilation, laryngoscopic intubation, accelerated arterial desaturation, postoperative monitoring and discharge status. In this review article pathophysiology, diagnosis, and perioperative management of this group of patients have been discussed in detail. PMID:19742249

    2016-01-01

    We have an enormous number of commensal bacteria in our intestine, moreover, the foods that we ingest and the water we drink is sometimes contaminated with pathogenic microorganisms. The intestinal epithelium is always exposed to such microbes, friend or foe, so to contain them our gut is equipped with specialized gut-associated lymphoid tissue (GALT), literally the largest peripheral lymphoid tissue in the body. GALT is the intestinal immune inductive site composed of lymphoid follicles such as Peyer’s patches. M cells are a subset of intestinal epithelial cells (IECs) residing in the region of the epithelium covering GALT lymphoid follicles. Although the vast majority of IEC function to absorb nutrients from the intestine, M cells are highly specialized to take up intestinal microbial antigens and deliver them to GALT for efficient mucosal as well as systemic immune responses. I will discuss recent advances in our understanding of the molecular mechanisms of M-cell differentiation and functions. PMID:26634447

    Obstructive sleep apnea (OSA) affects millions of Americans and is estimated to be as prevalent as asthma and diabetes. Given the fact that obesity is a major risk factor for OSA, and given the current global rise in obesity, the prevalence of OSA will increase in the future. Individuals with sleep apnea are often unaware of their sleep disorder. It is usually first recognized as a problem by family members who witness the apneic episodes or is suspected by their primary care doctor because of the individual's risk factors and symptoms. The vast majority remain undiagnosed and untreated, despite the fact that this serious disorder can have significant consequences. Individuals with untreated OSA can stop breathing hundreds of times a night during their sleep. These apneic events can lead to fragmented sleep that is of poor quality, as the brain arouses briefly in order for the body to resume breathing. Untreated, sleep apnea can have dire health consequences and can increase the risk of hypertension, diabetes, heart disease, and heart failure. OSA management has also become important in a number of comorbid neurological conditions, including epilepsy, stroke, multiple sclerosis, and headache. Diagnosis typically involves use of screening questionnaires, physical exam, and an overnight polysomnography or a portable home study. Treatment options include changes in lifestyle, positive airway pressure, surgery, and dental appliances. PMID:22368774

    Strangulated small bowel obstruction is a complication after abdominal surgery, which is rare in renal transplant patients. A 61-year-old man with a strangulated small bowel obstruction underwent renal transplant surgery 7 years before the current admission. He was admitted to our hospital for abdominal pain, nausea, and abdominal distention. An abdominal computed tomography and an ultrasound examination showed intestinal expansion and fluid collection without ascites. His disease was diagnosed as a small bowel obstruction and conservative treatment was begun. However, because of increasing abdominal pain and the collection of ascites, he underwent an emergency laparotomy and was diagnosed as having a strangulated small bowel obstruction. A fibrous cord had formed between the peritoneum (beside the transplanted kidney) and the root of the sigmoid mesocolon, strangulating the looped ileum and causing bleeding necrosis and hemorrhagic ascites collection. The cord and the necrotic ileum were resected, followed by an end-to-end anastomosis. He was discharged 17 days after the surgery in good condition. This is the first reported case of a person having a strangulated small bowel obstruction by a fibrous cord, who did not have a history of laparotomy after renal transplant. A strangulated small bowel obstruction after a renal transplant in a patient with no history of a laparotomy is a rare, but possible postoperative complications should be considered when making a differential diagnosis.

    Parenteral nutrition is a life-saving therapy for patients with intestinal failure. Intestinal transplantation is now recognized as a treatment for patients who develop complications of parenteral nutrition and in whom attempts at intestinal rehabilitation have failed. Patients with parenteral nutrition related liver disease will require a liver graft typically part of a multivisceral transplant. Isolated intestinal transplants are more commonly performed in adults while multivisceral transplants are most commonly performed in infants. Isolated intestinal transplants have the best short-term outcome, with over 80 % survival at 1 year. Patients requiring multivisceral transplants have a high rate of attrition with a 1 year survival less than 70 %. Prognostic factors for a poor outcome include patient hospitalization at the time of transplant and donor age greater than 40 years while systemic sepsis and acute rejection are the major determinant of early postoperative outcome. For patients surviving the first year the outcome of transplantation of the liver in addition to intestine affords some survival advantage though long-term outcome does not yet match other abdominal organs. Outcomes for intestinal retransplantation are poor as a result of immunology and patient debility. Overall intestinal transplantation continues to develop and is a clear indication with cost and quality of life advantages in patients with intestinal failure that do not remain stable on parenteral nutrition.

    Acute colonic pseudo-obstruction (ACPO) and chronic intestinal pseudo-obstruction (CIPO) are distinct clinical entities in which patients present similarly with symptoms of a mechanical obstruction without an occlusive lesion. Unfortunately, they also share the issues related to a delay in diagnosis, including inappropriate management and poor outcomes. Advancements have been made in our understanding of the aetiologies of both conditions. Several predisposing factors linked to critical illness have been implicated in ACPO. CIPO is a functional motility disorder, historically misdiagnosed, with unnecessary surgery being performed in many patients with dire consequences. This review discusses the pathophysiology, clinical and diagnostic features, and treatment of each. For ACPO, a safer pharmacological approach to treatment is presented in a modified up-to-date algorithm. The importance of CIPO as a differential diagnosis when seeing patients with recurrent admissions for abdominal pain and distention is also discussed, as well as specific indications for surgery. While surgery is often a last resort, the role of the surgeon in the management of both ACPO and CIPO cannot be undervalued. By characterizing each condition in a common review, the knowledge gleaned aims to optimize outcomes for these frequently complex patients.

    The incidence of the diverticulum of the small bowel varies from 0.2-1.3% in autopsy studies to 2.3% when assessed on enteroclysis. It occurs mostly in patients in the 6th decade of their life. Of all the small bowel diverticuli, jejunal diverticulum is the most common type. This rare entity is usually asymptomatic. However, they may cause chronic non-specific symptoms for a long period of time like dyspepsia, chronic postprandial pain, nausea, vomiting, borborgymi, alternating diarrhoea and constipation, weight loss, anaemia, steatorrhea or rarely lead to complications like haemorrhage, obstruction, perforation. Obstruction can be due to enterolith, adhesions, intussusception, and volvulus. The condition is difficult to diagnose because patients are generally presented with symptoms that mimic other diseases. It is important for clinicians to have awareness of this entity. Here, we present a case of multiple jejunal diverticuli with a history of repeated attacks of diverticulitis over past 20 years, which were misdiagnosed and now presented with intestinal obstruction due to volvulus of the involved segment along with mesentery around its axis. Resection of the diverticuli segment of jejunum was done with end-to-end jejuno-jejunal anastomosis. The patient is asymptomatic since 10 months of follow-up. PMID:27853337

    Patient: Male, 59 Final Diagnosis: Emphysematous epiglottitis Symptoms: Dysphonia • odynophagia • sore throat Medication: — Clinical Procedure: Direct laryngoscopy with incision and drainage of abscess Specialty: Otolaryngology Objective: Rare disease Background: Despite a shift in the epidemiology of epiglottitis following the introduction of the Haemophilus influenzae type B vaccine, acute infectious epiglottitis continues to be a relatively common and potentially life-threatening infection in adults. Epiglottitis complicated by abscess is rare, and emphysematous abscess is even less common. Early diagnosis and intervention is paramount in reducing morbidity and mortality. Although case reports exist, photographic depiction of this complication is not readily available. Case Report: We present the case of a 59-year-old male with rapidly progressive emphysematous epiglottitis managed with awake fiber optic intubation followed by incision, drainage, and antibiotic therapy. Early recognition and intervention in this patient led to complete resolution of the infection, with no long-term sequelae. Conclusions: Clinicians should be familiar with the radiographic and endoscopic findings which support an emphysematous abscess, as well as the treatment and airway management concerns in such cases.

    Ventricular function was evaluated using radionuclide ventriculography in 27 children with oropharyngeal obstruction and clinical features of obstructive sleep apnea. Their mean age was 3.5 years (9 months to 7.5 years). Conventional clinical assessment did not detect cardiac involvement in 25 of 27 children; however, reduced right ventricular ejection fraction (less than 35%) was found in 10 (37%) patients (mean: 19.5 +/- 2.3% SE, range: 8-28%). In 18 patients wall motion abnormality was detected. In 11 children in whom radionuclide ventriculography was performed before and after adenotonsillectomy, right ventricular ejection fraction rose from 24.4 +/- 3.6% to 46.7 +/- 3.4% (P less than 0.005), and in all cases wall motion showed a definite improvement. In five children, left ventricular ejection fraction rose greater than 10% after removal of oropharyngeal obstruction. It is concluded that right ventricular function may be compromised in children with obstructive sleep apnea secondary to adenotonsillar hypertrophy, even before clinical signs of cardiac involvement are present.

    Endoscopic balloon dilatation (EBD) and surgical intervention are two most common and effective treatments for gastric outlet obstruction. Correction of gastric outlet obstruction without the need for surgery is an issue that has been tried to be resolved in these decades; this management has developed with EBD, advanced treatments like local steroid injection, electrocauterization, and stent have been added recently. The most common causes of pediatric gastric outlet obstruction are idiopathic hypertrophic pyloric stenosis, peptic ulcer disease followed by the ingestion of caustic substances, stenosis secondary to surgical anastomosis; antral web, duplication cyst, ectopic pancreas, and other rare conditions. A complete clinical, radiological and endoscopic evaluation of the patient is required to make the diagnosis, with complimentary histopathologic studies. EBD are used in exceptional cases, some with advantages over surgical intervention depending on each patient in particular and on the characteristics and etiology of the gastric outlet obstruction. Local steroid injection and electrocauterization can augment the effect of EBD. The future of endoscopic treatment seems to be aimed at the use of endoscopic electrocauterization and balloon dilatations. PMID:27803770

    The cellular mechanisms that drive growth and remodeling of the early intestinal epithelium are poorly understood. Current dogma suggests that the murine fetal intestinal epithelium is stratified, that villi are formed by an epithelial remodeling process involving the de novo formation of apical surface at secondary lumina, and that radial intercalation of the stratified cells constitutes a major intestinal lengthening mechanism. Here, we investigate cell polarity, cell cycle dynamics and cell shape in the fetal murine intestine between E12.5 and E14.5. We show that, contrary to previous assumptions, this epithelium is pseudostratified. Furthermore, epithelial nuclei exhibit interkinetic nuclear migration, a process wherein nuclei move in concert with the cell cycle, from the basal side (where DNA is synthesized) to the apical surface (where mitosis takes place); such nuclear movements were previously misinterpreted as the radial intercalation of cells. We further demonstrate that growth of epithelial girth between E12.5 and E14.5 is driven by microtubule- and actinomyosin-dependent apicobasal elongation, rather than by progressive epithelial stratification as was previously thought. Finally, we show that the actin-binding protein Shroom3 is crucial for the maintenance of the single-layered pseudostratified epithelium. In mice lacking Shroom3, the epithelium is disorganized and temporarily stratified during villus emergence. These results favor an alternative model of intestinal morphogenesis in which the epithelium remains single layered and apicobasally polarized throughout early intestinal development. PMID:21880782

    Detecting eosinophilia in the nasal secretions of patients complaining of nasal obstruction makes it possible to identify a group of high risk patients. Hosty use of surgery in these patients carries a high risk of iatrogenic complications and little potential for improvement. The 2 most frequently used methods of obtaining cytologic specimens (swabbing versus washing) were compared in 37 patients with obstructive rhinitis (early stage polyposis and nonallergic rhinitis with eosinophilia syndrome, NARES). Swabbing gave reliable results. Eosinophilia was negligible in a group of 25 control subjects. The mean eosinophil count was 2.5% and only 1 patient had a positive cystogram. The 220 patients which nasal obstruction were classed in 5 groups according to the severity of clinical signs and symptoms. The mean eosinophil count and the percentage of patients with positive cystogram increased with increased severity of the clinical syndrome. 28 patients had uncomplicated obstructive rhinitis, 10 had NARES, 43 had allergic rhinitis, 52 had chronic obstructive rhinitis, and 87 had nasosinal polyposis. The respective mean eosinophil counts were 6.42%, 10.3%, 13.8% 16.8% and 31.4%. The percentage of patients with positive cytograms was respectively, 10.8%, 20%, 23.3%, 28.8% and 54%.

    The pathology of Crohn’s disease (CD) is characterized by obstructing intestinal strictures because of inflammation (with high levels of hemoglobin), fibrosis (high levels of collagen), or a combination of both. The accurate characterization of the strictures is critical for the management of CD. This study examines the feasibility of characterizing intestinal strictures by Photoacoustic imaging (PAI) without extrapolation from superficial biopsies. Ex vivo normal rat colon tissue, inflammatory and fibrotic intestinal strictures in rat trinitrobenzene sulfonic acid (TNBS) model were first differentiated by a PA-US parallel imaging system. Surgically removed human intestinal stricture specimens were afterwards imaged by a multiwavelength acoustic resolution PA microscope (ARPAM). The experiment results suggest that PAI is a potential tool for the diagnosis of the diseased conditions in intestinal strictures. PMID:27446710

    2016-01-01

    The intestinal barrier function contributes to gut homeostasis by modulating absorption of water, electrolytes, and nutrients from the lumen into the circulation while restricting the passage of noxious luminal substances and microorganisms. Chronic conditions such as rheumatoid arthritis, inflammatory bowel disease, and celiac disease are associated to intestinal barrier dysfunction. Here, the hypothesis is that a leaky intestinal wall allowing for indiscriminate passage of intraluminal compounds to the vascular compartment could in turn lead to systemic inflammation. An increasing number of studies are now investigating the association between gut permeability and CNS disorders, under the premise that translocation of intestinal luminal contents could affect CNS function, either directly or indirectly. Still, it is unknown whether disruption of intestinal barrier is a causative agent or a consequence in these situations. Here, we discuss the latest evidence pointing to an association between increased gut permeability and disrupted behavioral responses.

    2007-12-01

    Fetal lower urinary tract obstruction affects 2.2 per 10,000 births. It is a consequence of a range of pathological processes, most commonly posterior urethral valves (64%) or urethral atresia (39%). It is a condition of high mortality and morbidity associated with progressive renal dysfunction and oligohydramnios, and hence fetal pulmonary hypoplasia. Accurate detection is possible via ultrasound, but the underlying pathology is often unknown. In future, magnetic resonance imaging (MRI) may be increasingly used alongside ultrasound in the diagnosis and assessment of fetuses with lower urinary tract obstruction. Fetal urine analysis may provide improvements in prenatal determination of renal prognosis, but the optimum criteria to be used remain unclear. It is now possible to decompress the obstruction in utero via percutaneous vesico-amniotic shunting or cystoscopic techniques. In appropriately selected fetuses intervention may improve perinatal survival, but long-term renal morbidity amongst survivors remains problematic.

    Recurrent airway obstruction is a widely recognised airway disorder, characterised by hypersensitivity-mediated neutrophilic airway inflammation and lower airway obstruction in a subpopulation of horses when exposed to suboptimal environments high in airborne organic dust. Over the past decade, numerous studies have further advanced our understanding of different aspects of the disease. These include clarification of the important inhaled airborne agents responsible for disease induction, improving our understanding of the underlying genetic basis of disease susceptibility and unveiling the fundamental immunological mechanisms leading to establishment of the classic disease phenotype. This review, as well as giving a clinical overview of recurrent airway obstruction, summarises much of the work in these areas that have culminated in a more thorough understanding of this debilitating disease.

    Trans - omental hernia is very rare, accounting to 1-4% of all internal hernias which is an unusual cause of small bowel obstruction. Here we present a case report of a small bowel obstruction in a female due to trans - omental hernia presenting with central abdominal pain, distension and bilious vomiting. She had no previous history of trauma, surgery. Plain X-ray abdomen erect showed multiple air fluid levels with dilated small bowel loops. Emergency laparotomy revealed a segment of congested small bowel loop (ileum) through a defect in greater omentum. On table the herniated bowel loop was reduced and the defect in greater omentum was closed primarily. There was no necessity for bowel resection as it regained normal colour after reduction. Postoperative period was uneventful with complete resolution of symptoms. This case is presented for its rarity and its importance in clinical differential diagnosis of acute abdomen due to small bowel obstruction.

    Patients with stomas often present with bowel obstruction, often secondary to adhesions. This case describes the presentation, investigation and management of a 62-year-old woman with an end ileostomy, who presented to hospital with acute abdominal pain and subacute bowel obstruction. Further questioning revealed the recent ingestion of an apricot stone and this was identified by multimodality imaging as the cause of the luminal obstruction in the distal ileum, just proximal to the stoma. After a failed period of conservative management, examination under anaesthesia was performed and digital extraction attempted, but this was unsuccessful. Rather than surgical stoma revision, endoscopic removal was achieved. The patient improved and was discharged the following day. However, her small bowel obstruction relapsed within 48 h. She was readmitted and underwent stoma revision with no further problems.

    Fourth ventricular outlet obstruction (FVOO) is a rare cause of obstructive hydrocephalus. Although FVOO accompanied by malformative syndrome and secondary causes of obstruction are common, there are few reports of primary FVOO (PFVOO). The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a rare presenting feature of hydrocephalus. A 1-year, 8-month-old boy with a normal head circumference developed SIADH accompanied by rapid deterioration of symptoms of intracranial hypertension. PFVOO was diagnosed because magnetic resonance imaging revealed an enlarged ventricular system with a barely visible membranous obstacle at the foramen of Magendie. All symptoms were resolved by endoscopic third ventriculostomy. PFVOO should be considered as a rare form of congenital obstructive hydrocephalus, especially in patients with tetraventricular hydrocephalus. To the best of our knowledge, this is the first case of an infant with SIADH, resulting from acute deterioration of non-tumoral raised pressure hydrocephalus.

    Obstructive sleep apnea (OSA) is a sleep respiratory disorder characterized by recurrent episodes of complete or partial airway obstruction, resulting in apneas or hypopneas. OSA could contribute to atherosclerosis through direct and indirect mechanisms. Endothelial dysfunction, sympathetic stimulation, and proinflammatory cytokine modulation caused by OSA play significant role to an atherosclesrotic event. Other risk factors of atherosclerosis like hypertension and diabetes mellitus also associated with OSA. Animal and clinical studies recently showed promising data to prove association between OSA, atherosclerosis, and its risk factors. However, provided data has not showed consistent result. In the future, demand of further research both basic and clinical sciences need to be fulfilled.

    A major task of the intestine is to form a defensive barrier to prevent absorption of damaging substances from the external environment. This protective function of the intestinal mucosa is called permeability. Clinicians can use inert, nonmetabolized sugars such as mannitol, rhamnose, or lactulose to measure the permeability barrier or the degree of leakiness of the intestinal mucosa. Ample evidence indicates that permeability is increased in most patients with Crohn's disease and in 10% to 20% of their clinically healthy relatives. The abnormal leakiness of the mucosa in Crohn's patients and their relatives can be greatly amplified by aspirin preadministration. Permeability measurements in Crohn's patients reflect the activity, extent, and distribution of the disease and may allow us to predict the likelihood of recurrence after surgery or medically induced remission. Permeability is also increased in celiac disease and by trauma, burns, and nonsteroidal anti-inflammatory drugs. The major determinant of the rate of intestinal permeability is the opening or closure of the tight junctions between enterocytes in the paracellular space. As we broaden our understanding of the mechanisms and agents that control the degree of leakiness of the tight junctions, we will be increasingly able to use permeability measurements to study the etiology and pathogenesis of various disorders and to design or monitor therapies for their management.

  1. Intrarenal Doppler Indices in Acute Ureteric Obstruction

    PubMed Central

    2014-01-01

    Context: Urolithiasis remains a major health problem despite advances in therapy. Obstruction results in an increase in pressure within the urinary tract, causing structural and physiologic changes. This study aimed to calculate the intra renal Resistivity Index (RI) of acutely obstructed kidney, to determine the significance of Resistivity Index Ratio (RIR) and difference in Resistivity Index of obstructed and contralateral non obstructed kidney. Materials and Methods: Prospective study with renal Doppler for patients presenting with acute unilateral ureteric obstruction. Seventy two patients between the age group 20-45 y presenting to the Department of Radiodiagnosis, between January – December 2006 with acute unilateral ureteric obstruction were included in the study. Gray scale and Doppler evaluation of the kidneys done; with assessment of the ureteric calculus. Renal Doppler indices calculated and follow up of the same done after relief of obstruction. Statistical Analysis: Statistical analysis was done using SPSS Software V13 and p-value <0.05 was considered as statistically significant. Results: Forty two patients (58.33%) had mild, 28 (38.89%) moderate and 2 (2.78%) severe hydronephrosis. The mean RI of the obstructed kidney was 0.66±0.88 and that of contralateral non obstructed kidney was 0.569±0.05. Delta RI between the obstructed and contralateral non obstructed kidney was 0.08±0.03. The mean RIR between the obstructed and non obstructed kidney was 1.12±0.04 and the same after relief of obstruction was 1.03±0.06. Conclusion: The intrarenal Resistivity indices are less sensitive indicators in predicting the diagnosis of acute ureteric obstruction, although Resistivity Index Ratio appears to be a better parameter. The indices within the normal range do not rule out the absence of obstruction. Hence these parameters should not be interpreted in isolation. PMID:25654006

    A 6-yr-old male red kangaroo (Macropus rufus) presented for a history of inappetance, abnormal behavior, and unconfirmed elimination for 6 hr prior to presentation. Based on abdominal ultrasound, abdominocentesis, and cystocentesis, a presumptive diagnosis of urinary tract obstruction with uroabdomen and hydronephrosis was reached. Abdominal radiographs did not assist in reaching an antemortem diagnosis. Postmortem examination confirmed a urinary bladder rupture secondary to urethral obstruction by a single urethrolith. Bilateral hydronephrosis and hydroureter were identified and determined to be a result of bilateral ureteroliths. Urolith analysis revealed a composition of 100% calcium carbonate. A dietary analysis was performed, implicating an increased Ca:P ratio from a food preparation miscommunication as a contributing factor. Appropriate husbandry changes were made, and mob surveillance procedures were performed, which resolved the urolithiasis risk for the remaining five animals.

    Chilaiditi sign is named after the Greek radiologist Demetrius Chilaiditi who first described it when he was working in Vienna In (1910), and it is an incidental radiographic finding. This sign can be more frequently mistaken for pneumoperitoneum which is usually an indication of bowel perforation and can lead to needless surgical intervention. There are several case report reported in literature that describe the association between colonic volvulus and Chilaiditi syndrome that underline the frequent association between these anatomical condition instead no previous report described the association between Chilaiditi syndrome and large bowel obstruction secondary to a malignant sigmoid stenosis in a man presenting with symptoms and signs of upper respiratory distress combined with subacute bowel obstruction.

    Background Epiphora secondary to acquired nasolacrimal duct obstruction is a common ophthalmic problem in adults requiring surgical management. External dacryocystorhinostomy (DCR) is a reliable but difficult surgical technique for the treatment of nasolacrimal duct obstruction. Purpose To evaluate the success rate and complications of modified external DCR in patients with primary acquired nasolacrimal duct obstruction. Materials and Methods This hospital based prospective interventional study included 56 patients with primary acquired nasolacrimal duct obstruction. Diagnosis of nasolacrimal duct obstruction was made through irrigation of the nasolacrimal drainage system. All patients were operated by modified technique of external DCR with anastomosis of the anterior lacrimal and nasal mucosal flaps only, whereas posterior mucosal flaps were excised. Patients were followed up for a period of 6 months. During the follow up, success rate and complications if any were recorded. Success was defined objectively by a patent lacrimal passage on irrigation and subjectively by the absence of watering or discharge. Results The mean age of the study population was 39.23 ± 10.66 years, and 78.6% of patients were females (male to female ratio 1:3.7). The average operation time was 36.48 ± 4.72 minutes. Objective and subjective success rates were 92.9% and 89.3%, respectively after a follow up period of 6 months. Intraoperatively, haemorrhage occurred in 3 patients (5.3%) and laceration of the nasal mucosa in 4 patients (7.1%). Postoperative complications included significant lid swelling and periorbital ecchymosis in 3 patients (5.3%), epistaxis in 2 patients (3.6%) and hypertrophic scar in 2 patients (3.6%). Conclusion These results suggest that modified external DCR with anterior flaps anastomosis only is a simple, safe, less time consuming surgical technique that is easy to perform, and the outcome is comparable to conventional DCR.

    The computed tomographic appearance of collapse without endobronchial obstruction is reviewed. These 57 cases were classified by the etiology of collapse. The largest group consisted of 29 patients with passive atelectasis, i.e., collapse secondary to fluid, air, or both in the pleural space. Twenty-three of 29 proved secondary to malignant pleural disease. Computed tomography accurately predicted a malignant etiology in 22 of 23 cases. The second largest group of patients had lobar collapse secondary to cicatrization from chronic inflammation. In all cases the underlying etiology was tuberculosis. Radiation caused adhesive atelectasis in six patients secondary to a lack of production of surfactant. In each case a sharp line of demarcation could be defined between normal and abnormal collapsed pulmonary parenchyma. Three cases of unchecked tumor growth caused a peripheral form of collapse (replacement atelectasis). This form of collapse was characterized by an absence of endobronchial obstruction and extensive tumor not delineated by the normal boundaries of the pulmonary lobes.

    In biochemical terms, the rat small intestine is relatively immature at birth and for the first two postnatal weeks. Then during the third week a dramatic array of enzymic changes begins, and by the end of the fourth week the intestine has the digestive and absorptive properties of the adult. Selective examples of these changes are discussed with emphasis on their implications for toxicological studies. The review also includes a detailed consideration of the roles of the dietary change of weaning and of glucocorticoid and thyroid hormones in the regulation of intestinal development. PMID:575507

    Metabolic syndrome is characterized by low-grade chronic systemic inflammation, which is associated with intestinal hyperpermeability. This study examined the effects of 3 high-fat diets (HFDs) composed of different fat sources (soybean oil and lard) on the intestinal permeability, tight junction (TJ) protein expression, and cecal bile acid (BA) concentrations in mice, and then analyzed their interrelations. C57/BL6 mice were fed the control diet, HFD (soybean oil), HFD (lard), and HFD (mix; containing equal concentrations of soybean oil and lard) for 8 wk. Glucose tolerance, intestinal permeability, TJ protein expression, and cecal BA concentration were evaluated. Feeding with the 3 HDFs similarly increased body weight, liver weight, and fat pad weight, and induced glucose intolerance and intestinal hyperpermeability. The expression of TJ proteins, zonula occludens-2 and junctional adhesion molecule-A, were lower in the colons of the 3 HFD groups than in the control group (P < 0.05), and these changes appeared to be related to intestinal hyperpermeability. Feeding with HFDs increased total secondary BA (SBA) and total BA concentrations along with increases in some individual BAs in the cecum. Significant positive correlations between intestinal permeability and the concentrations of most SBAs, such as deoxycholic acid and ω-muricholic acids, were detected (P < 0.05). These results suggest that the HFD-induced intestinal hyperpermeability is associated with increased BA secretion. The abundance of SBAs in the large intestine may be responsible for the hyperpermeability.

  12. Phytobezoar in a jejunal diverticulum as a cause of small bowel obstruction: a case report

    PubMed Central

    2011-01-01

    Introduction Phytobezoars are concretions of poorly digested fruit and vegetable fibers found in the alimentary tract. Previous gastric resection, gastrojejunostomy, or pyloroplasty predispose people to bezoar formation. Small-bowel bezoars normally come from the stomach, and primary small-bowel bezoars are very rare. They are seen only in patients with underlying small-bowel diseases such as diverticula, strictures, or tumors. Primary small-bowel bezoars almost always present as intestinal obstructions, although it is a very rare cause, being responsible for less than 3% of all small-bowel obstructions in one series. Jejunal diverticula are rare, with an incidence of less than 0.5%. They are usually asymptomatic pseudodiverticula of pulsion type, and complications are reported in 10% to 30% of patients. A phytobezoar in a jejunal diverticulum is an extremely rare presentation. Case presentation A 78-year-old Pakistani man presented to our clinic with small-bowel obstruction. Upon exploration, we found a primary small-bowel bezoar originating in a jejunal diverticulum and causing jejunal obstruction. Resection and anastomosis of the jejunal segment harboring the diverticulum was performed, and our patient had an uneventful recovery. Conclusion Primary small-bowel bezoars are very rare but must be kept in mind as a possible cause of small-bowel obstruction. PMID:21951579

    Introduction Bezoar is an unusual cause of small bowel obstruction accounting for 0.4–4% of all mechanical bowel obstruction. The common site of obstruction is terminal ileum. Case report A 28-year-old male with no past surgical history, known to have severe mental retardation presented with anorexia. CT scan demonstrated dilated small bowel loops and intraluminal ileal mass with mottled appearance. At exploratory laparotomy, a bezoar was found impacted in the terminal ileum 5–6 inches away from the ileocecal valve and was removed through an enterotomy. Discussion Bezoars are concretions of fibers or foreign bodies in the alimentary tract. Small bowel obstruction is one of common clinical symptoms. The typical finding of well-defined intraluminal mass with mottled gas pattern in CT scan is suggestive of an intestinal bezoar. The treatment option of bezoar is surgery including manual fragmentation of bezoar and pushing it toward cecum, enterotomy or segmental bowel resection. Thorough exploration of abdominal cavity should be done to exclude the presence of concomitant bezoars. Recurrence is common unless underlying predisposing condition is corrected. Conclusions Bezoar-induced small bowel obstruction remains an uncommon diagnosis. It should be suspected in patients with an increased risk of bezoar formation, such as in the presence of previous gastric surgery, a history suggestive of increased fiber intake, or patient with psychiatric disorders. CT scan is helpful for preoperative diagnosis. PMID:26764889

  15. Intestinal adaptation following resection.

    PubMed

    Tappenden, Kelly A

    2014-05-01

    Intestinal adaptation is a natural compensatory process that occurs following extensive intestinal resection, whereby structural and functional changes in the intestine improve nutrient and fluid absorption in the remnant bowel. In animal studies, postresection structural adaptations include bowel lengthening and thickening and increases in villus height and crypt depth. Functional changes include increased nutrient transporter expression, accelerated crypt cell differentiation, and slowed transit time. In adult humans, data regarding adaptive changes are sparse, and the mechanisms underlying intestinal adaptation remain to be fully elucidated. Several factors influence the degree of intestinal adaptation that occurs post resection, including site and extent of resection, luminal stimulation with enteral nutrients, and intestinotrophic factors. Two intestinotrophic growth factors, the glucagon-like peptide 2 analog teduglutide and recombinant growth hormone (somatropin), are now approved for clinical use in patients with short bowel syndrome (SBS). Both agents enhance fluid absorption and decrease requirements for parenteral nutrition (PN) and/or intravenous fluid. Intestinal adaptation has been thought to be limited to the first 1-2 years following resection in humans. However, recent data suggest that a significant proportion of adult patients with SBS can achieve enteral autonomy, even after many years of PN dependence, particularly with trophic stimulation.

    Intestines are organs that not only digest food and absorb nutrients, but also provide a defense barrier against pathogens and noxious agents ingested. Tight junctions (TJs) are the most apical component of the junctional complex, providing one form of cell-cell adhesion in enterocytes and playing a critical role in regulating paracellular barrier permeability. Alteration of TJs leads to a number of pathophysiological diseases causing malabsorption of nutrition and intestinal structure disruption, which may even contribute to systemic organ failure. Claudins are the major structural and functional components of TJs with at least 24 members in mammals. Claudins have distinct charge-selectivity, either by tightening the paracellular pathway or functioning as paracellular channels, regulating ions and small molecules passing through the paracellular pathway. In this review, we have discussed the functions of claudin family members, their distribution and localization in the intestinal tract of mammals, their alterations in intestine-related diseases and chemicals/agents that regulate the expression and localization of claudins as well as the intestinal permeability, which provide a therapeutic view for treating intestinal diseases.

    Embryogenesis offers a real laboratory for pattern formation, buckling, and postbuckling induced by growth of soft tissues. Each part of our body is structured in multiple adjacent layers: the skin, the brain, and the interior of organs. Each layer has a complex biological composition presenting different elasticity. Generated during fetal life, these layers will experience growth and remodeling in the early postfertilization stages. Here, we focus on a herringbone pattern occurring in fetal intestinal tissues. Common to many mammalians, this instability is a precursor of the villi, finger-like projections into the lumen. For avians (chicks' and turkeys' embryos), it has been shown that, a few days after fertilization, the mucosal epithelium of the duodenum is smooth, and then folds emerge, which present 2 d later a pronounced zigzag instability. Many debates and biological studies are devoted to this specific morphology, which regulates the cell renewal in the intestine. After reviewing experimental results about duodenum morphogenesis, we show that a model based on simplified hypothesis for the growth of the mesenchyme can explain buckling and postbuckling instabilities. Being completely analytical, it is based on biaxial compressive stresses due to differential growth between layers and it predicts quantitatively the morphological changes. The growth anisotropy increasing with time, the competition between folds and zigzags, is proved to occur as a secondary instability. The model is compared with available experimental data on chick's duodenum and can be applied to other intestinal tissues, the zigzag being a common and spectacular microstructural pattern of intestine embryogenesis.

    AIM: To determine the possible predisposing factors of bezoar-induced small bowel obstruction (BI-SBO) and to discuss the diagnostic value of multi-slice spiral computed tomography, particularly contrast-enhanced scanning, in this condition. METHODS: A total of 35 BI-SBO cases treated at our hospital from January 2007 to December 2013 were retrospectively analysed. Complete clinical and computed tomography (CT) data of the patients were available and confirmed by surgery. SBO was clinically diagnosed on the basis of clinical manifestations. Of the 35 patients, 18 underwent abdominal and pelvic CT planar scanning with GE 64-slice spiral CT and 17 underwent abdominal and pelvic CT planar scanning with GE 64-slice spiral CT combined with contrast-enhanced examination. Original images were processed using a GE ADW4.3 workstation to obtain MPR, CPR, MIP and CTA images. The images of all patients were evaluated by two abdominal imaging experts. The main analytical contents of planar scanning included intestinal bezoar conditions, changes in the intestinal wall and changes in peri-intestinal conditions. Vascular hyperaemia and arterial blood supply conditions at a specific obstruction site and the distal end of the obstruction site were evaluated through contrast-enhanced examination. RESULTS: The proportion of males to females among the 35 cases was 1:1.69 (13:22); median age was 63.3 years. The following cases were observed: 29 (82.8%) cases occurred in autumn and winter and showed a history of consuming high amounts of persimmon and hawthorn; 19 (54.3%) cases revealed a history of gastrointestinal surgery; 19 exhibited incomplete dentition, with missing partial or whole posterior teeth; 26 suffered from obstruction at the ileum. A total of 51 bezoars were found in these patients, of whom 16 (45.7%) had multiple bezoars. CT planar scanning of bezoars showed lumps with mottled gas inside the intestinal cavity. Furthermore, 9 cases of bezoars had envelopes and 11 cases

    Primary intestinal lymphangiectasia (PIL) is rare disorder characterized by congenital malformation or obstruction of intestinal lymphatic drainage; it is responsible for protein losing enteropathy leading to lymphopenia, hypoalbuminemia and hypogammaglobulinemia. A low-fat diet associated with medium-chain triglyceride supplementation is the cornerstone of PIL management. The administration of intravenous immunoglobulins does not always lead to satisfactory plasma levels and therefore the replacement therapy with immunoglobulins is controversial. We describe here the case of a patient with PIL and severe hypogammaglobulinemia treated with immunoglobulins. The striking aspect of this case is the clinical and serological benefit obtained with the subcutaneous compared to the intravenous immunoglobulins administration.

    Cellulose fiber diet pills have recently become a popular form of weight control. In the past 2 months, we have seen two patients in whom ingestion of these pills has resulted in complete distal esophageal obstruction. Further studies revealed that each patient had a previously undiagnosed anatomical abnormality of the distal esophagus; in one case a Schatzki's ring, and in the other a stricture probably secondary to chronic reflux. We conclude that patients with known esophageal narrowing, or with a history of reflux and/or dysphagia, should use cellulose fiber diet pills only with extreme caution.

    The incidence of late radiation injury of the esophagus is not precisely determined but, overall, the occurrence of clinically apparent damage is infrequent. The authors report a complete esophageal obstruction in a 21-year-old man, 14 years after chemo-radiation therapy for Hodgkin's lymphoma. Although endoscopy failed to demonstrate a gross morphologic abnormality, an esophagogram detected abnormal peristalsis and stricture, and esophageal manometry coupled with dynamic isotopic study clearly demonstrated a multilevel secondary neuronal damage. Data in the literature suggest that alteration in motility is by far the most frequent radiologic manifestation. Further prospective studies will probably clarify the actual incidence of late esophageal damage after chemo-radiation therapy.

    Secondary rhinoplasty is very usual. Some patients are not satisfied by the previous surgery because the result is poor with obvious defaults but, sometimes, the result is good but the patient expects perfection. These two different situations will not lead to the same answer from the surgeon. Techniques of secondary rhinoplasty are the same than primary, but are often more difficult to perform because of scar tissue, retraction and loss of lining. The authors analyse the more frequent deformities in secondary rhinoplasty and the way they fix them.

    The parathyroid glands secrete parathyroid hormone (PTH), which is important for maintaining calcium homeostasis. Parathyroid gland hyperplasia and subsequent hyperparathyroidism can occur secondary to chronic renal failure in dogs, resulting in significant alterations in calcium metabolism. Renal secondary hyperparathyroidism is a complex, multifactorial syndrome that involves changes in circulating levels of calcium, PTH, phosphorus, and 1,25-dihydroxycholecalciferol (calcitriol). An increased PTH level can have deleterious effects, including soft tissue mineralization, fibrous osteodystrophy, bone marrow suppression, urolithiasis, and neuropathy. Dietary phosphorus restriction, intestinal phosphate binders, and calcitriol supplementation may slow the progression of renal disease and decrease PTH concentrations in animals with secondary hyperparathyroidism; however, the prognosis for these animals is guarded to poor.

    According to the U.S. Department of Health and Human Services, digestive disease affects 60 to 70 million people and costs over 140 billion annually. Despite the significance of the gastrointestinal tract to human health, the physics of digestion remains poorly understood. In this study, we ask a simple question: what sets the frequency of intestinal contractions? We measure the frequency of intestinal contractions in rats, as a function of distance down the intestine. We find that intestines Contract radially ten times faster than longitudinally. This motion promotes mixing and, in turn, absorption of food products by the intestinal wall. We calculate viscous dissipation in the intestinal fluid to rationalize the relationship between frequency of intestinal contraction and the viscosity of the intestinal contents. Our findings may help to understand the evolution of the intestine as an ideal mixer.

    AIM: To investigate the mechanisms of Lactobacillus plantarum (L. plantarum) action on gut barrier in preoperative and postoperative experimental obstructive jaundice in rats. METHODS: Forty rats were randomly divided into groups of sham-operation, bile duct ligation (BDL), BDL + L. plantarum, BDL + internal biliary drainage (IBD), and BDL + IBD + L. plantarum. Ten days after L. plantarum administration, blood and ileal samples were collected from the rats for morphological examination, and intestinal barrier function, liver function, intestinal oxidative stress and protein kinase C (PKC) activity measurement. The distribution and expression of the PKC and tight junction (TJ) proteins, such as occludin, zonula occludens-1, claudin-1, claudin-4, junction adhesion molecule-A and F-actin, were examined by confocal laser scanning microscopy, immunohistochemistry, Western blotting, real-time fluorescent quantitative polymerase chain reaction assay. RESULTS: L. plantarum administration substantially restored gut barrier, decreased enterocyte apoptosis, improved intestinal oxidative stress, promoted the activity and expression of protein kinase (BDL vs BDL + L. plantarum, 0.295 ± 0.007 vs 0.349 ± 0.003, P < 0.05; BDL + IBD vs BDL + IBD + L. plantarum, 0.407 ± 0.046 vs 0.465 ± 0.135, P < 0.05), and particularly enhanced the expression and phosphorylation of TJ proteins in the experimental obstructive jaundice (BDL vs BDL + L. plantarum, 0.266 ± 0.118 vs 0.326 ± 0.009, P < 0.05). The protective effect of L. plantarum was more prominent after internal biliary drainage ( BDL + IBD vs BDL + IBD + L. plantarum, 0.415 ± 0.105 vs 0.494 ± 0.145, P < 0.05). CONCLUSION: L. plantarum can decrease intestinal epithelial cell apoptosis, reduce oxidative stress, and prevent TJ disruption in biliary obstruction by activating the PKC pathway. PMID:22912548

What is not in doubt is that intestinal permeability in patients with Crohn's disease is increased proportional to disease activity; it can be used to predict clinical relapse of disease and prognosis; and a small proportion of first-degree relatives have increased intestinal permeability. This last finding has been subject to much speculation. In particular it has been suggested that it represents a genetically determined abnormality. If so it might play an important pathogenic process in the disease. However this permeability change in relatives does not conform to a classical inheritance pattern and in some studies it is found in the patients' spouses. This suggests an environmental cause for the changes. However proponents of an environmental factor have been singularly inactive in attempting to identify this agent(s). In view of recent research it seems likely that the increased intestinal permeability in relatives of Crohn's patients may be secondary to sub-clinical intestinal inflammation. This inflammation conforms to an inherited additive trait. The genetic basis for this inflammation is being studied.

    Mechanical obstruction of the biliary tree and resultant stasis are the cornerstone of a spectrum of diseases ranging from biliary colic to fulminant cholangitis. Infrequently acquired abnormalities of the abdominal vasculature can lead to biliary obstruction. In 2010, we reported a case of acute cholangitis resulting from compression of extra hepatic bile duct by an abdominal aortic aneurysm (AAA). We subsequently conducted a follow up scoping review of literature to identify other cases of acquired abdominal arterial abnormalities resulting in biliary obstruction looking at their management and outcomes. The articles were independently reviewed by two of the authors and pertinent data was extracted. The data was divided on an anatomic basis into two groups: one with primary aortic pathology and one with splanchnic vessel pathology. We identified 39 cases of biliary obstruction secondary to acquired aortic or splanchnic vessel abnormalities; 16 were caused by AAAs and 23 by splanchnic vessels. The cases were managed via conservative, endoscopic, endovascular or open surgical options based on the available technology and expertise. Although uncommon, recognition of aortic and splanchnic arterial abnormalities as a potential cause of biliary obstruction is important as management entails not only cautious decompression of the biliary tree but also addressing the underlying vascular pathology. We recommend that extrinsic biliary compression by an aneurysm or pseudoaneurysm be considered among the differential diagnosis in patients presenting with biliary obstruction and a known lesion of the abdominal vasculature.

    Symptoms of sleep-disordered breathing, especially obstructive sleep apnea syndrome (OSAS), are common in asthma patients and have been associated with asthma severity. It is known that asthma symptoms tend to be more severe at night and that asthma-related deaths are most likely to occur during the night or early morning. Nocturnal symptoms occur in 60-74% of asthma patients and are markers of inadequate control of the disease. Various pathophysiological mechanisms are related to the worsening of asthma symptoms, OSAS being one of the most important factors. In patients with asthma, OSAS should be investigated whenever there is inadequate control of symptoms of nocturnal asthma despite the treatment recommended by guidelines having been administered. There is evidence in the literature that the use of continuous positive airway pressure contributes to asthma control in asthma patients with obstructive sleep apnea and uncontrolled asthma.

  10. Treatment of ureteral calculus obstruction with laser lithotripsy in an Atlantic bottlenose dolphin (Tursiops truncatus).

    PubMed

    2012-03-01

    An adult female bottlenose dolphin (Tursiops truncatus) presented with acute anorexia secondary to progressive azotemia (blood urea nitrogen = 213 mg/dl, creatinine [Cr] = 9.5 mg/dl) and electrolyte abnormalities (K = 7.4 mEq/L). It was later diagnosed with postrenal obstruction secondary to bilaterally obstructing ureteral calculi seen on ultrasound. Treatment of the obstruction required two endoscopic procedures, cystoscopy for ureteral stent placement and ureteroscopy to perform intracorporeal lithotripsy on the obstructing calculi. Before the first procedure, the dolphin's azotemia was stabilized with aggressive fluid therapy, peritoneal dialysis, and treatment for acidosis. Diuresis subsequent to the fluid therapy enabled passage of the right obstructing urolith. For both endoscopic procedures, the dolphin was placed in left lateral recumbency due to the peritoneal dialysis catheter in the right retroperitoneal region. For the first procedure, a 12-French (Fr) flexible cystoscope was inserted retrograde into the bladder via the urethra, whereupon a calculus was seen obstructing the left ureteral orifice. A 4.8-Fr, 26-cm double-pigtail ureteral stent was placed up the left ureter to relieve the postrenal obstruction. Inadvertent proximal migration of the left ureteral stent occurred during the procedure. However, renal parameters (serum Cr = 5.8, K = 5.4) improved significantly by the next day. For the second procedure, 28 hr later, ureteroscopy was performed to treat the calculus and replace the existing stent with a longer stent. The left ureteral calculus was pulverized into tiny fragments by using a holmium:yttrium-aluminum-garnet laser inserted through a 6.9-Fr semirigid ureteroscope. The migrated stent was visualized in the distal left ureter and replaced with a 90-cm single-pigtail ureteral stent that was sutured exterior to the urogenital slit and removed 3 days later. Renal function normalized over the next several days, and the dolphin recovered over

    Silicone drains are often placed in the abdominal cavity for prophylactic reasons. One complication resulting from drainage includes visceral herniation at the drain site of the abdominal wall defect. An 82-year-old woman underwent a laparotomy for a large pelvic mass. After the operation, she developed small bowel incarceration, which was caused by aggressive drain extraction. Subsequent surgical treatment resulted in the patient's full recovery. This case emphasises the unusual causative mechanism of intestinal obstruction. Drains should be placed carefully in the abdominal cavity in strictly selected cases, only when it is reasonable to do so.

    Intestinal transplantation has shown exceptional growth over the past 10 years. At the end of the 1990’s, intestinal transplantation moved out of the experimental realm to become a routine practice in treating patients with severe complications related to total parenteral nutrition and intestinal failure. In the last years, several centers reported an increasing improvement in survival outcomes (about 80%), during the first 12 months after surgery, but long-term survival is still a challenge. Several advances led to clinical application of transplants. Immunosuppression involved in intestinal and multivisceral transplantation was the biggest gain for this procedure in the past decade due to tacrolimus, and new inducing drugs, mono- and polyclonal anti-lymphocyte antibodies. Despite the advancement of rigid immunosuppression protocols, rejection is still very frequent in the first 12 months, and can result in long-term graft loss. The future of intestinal transplantation and multivisceral transplantation appears promising. The major challenge is early recognition of acute rejection in order to prevent graft loss, opportunistic infections associated to complications, post-transplant lymphoproliferative disease and graft versus host disease; and consequently, improve results in the long run.

    Trigeminal schwannomas represent between 0.07% and 0.36% of all intracranial tumors and 0.8% to 8% of intracranial schwannomas. Selection of the appropriate management strategy requires an understanding of the tumor’s natural history and treatment outcomes. This report describes the case of a 36-year-old male who presented with a three-month history of progressive headaches, dizziness, loss of balance, decreased sleep, and cognitive decline. Magnetic resonance imaging revealed a large enhancing lesion centered around the left Meckel’s cave and extending into both the middle and the posterior fossa with obstructive hydrocephalus secondary to compression of the fourth ventricle. Resection of the posterior fossa component of the tumor was performed in order to relieve the mass effect upon the brainstem without attempting a radical removal of the middle fossa component and a potential risk of further cognitive impairment. The pathological exam confirmed the diagnosis of a trigeminal schwannoma. The residual tumor showed progressive spontaneous volumetric shrinkage after a subtotal surgical resection. This case shows the value of a planned conservative surgery in complex schwannomas and highlights the challenges in interpreting the treatment responses in these benign tumors, whether approached surgically or with stereotactic radiation techniques.

    We have evaluated the immunological abnormalities present in a 6 year old patient with primary intestinal and generalized lymphangiectasia confirmed by intestinal, lung and lymph node biopsies. Lymphocyte loss through the gut was confirmed by the detection of lymphocytes in her stool. An increased enteric protein loss was suggested by hypoproteinaemia, peripheral oedema, and a very short half-life for i.v. immune serum globulin (3 days). Lymphocyte subpopulation analysis revealed a selective loss of T lymphocytes, with a proportionally increased loss of the OKT4 positive helper/inducer subpopulation. Functionally, there was a decrease in proliferative responses to some mitogens and to allogeneic cells, and a lack of T cell help for in vitro B lymphocyte differentiation into immunoglobulin secreting cells. Natural killer function was normal. In this patient, a concomitant thymic deficiency was documented by failure to identify thymic tissue on a thymus biopsy and by an absence or decrease of the serum thymic factor (thymulin) and thymosin alpha 1. No compensatory lymphopoiesis was detected in the bone marrow. In an attempt to increase T lymphocyte development, the patient was treated with thymosin fraction 5. Daily treatment with this preparation resulted in a transient clinical improvement which could not be sustained on a weekly thymosin treatment schedule. However, lymphocyte numbers did not increase during this treatment. The findings in this patient support the notion that T lymphocytes are needed to stimulate thymic epithelium. In situations of excessive loss of long lived T lymphocytes a secondary thymic atrophy may occur and further contribute to the development of a deficiency in cell-mediated immunity.

    A case of intestinal anisakidosis in a 42-year-old man in Japan is presented. His chief complaint was an acute onset of severe abdominal pain. Approximately 12 hours before the onset of this symptom, he had eaten sliced raw mackerel ("sashimi"). Upper endoscopy was unremarkable. At exploratory laparotomy, an edematous, diffusely thickened segment of jejunum was observed, which was resected. The postoperative course was uneventful. The segment of small intestine showed a granular indurated area on the mucosal surface, and microscopically, a helminthic larva penetrating the intestinal wall, which was surrounded by a cuff of numerous neutrophils and eosinophils, as well as diffuse acute serositis. A cross section of the larva revealed the internal structures, pathognomonic of Anisakis simplex. Although anisakidosis is rare in the United States, with the increasing popularity of Japanese cuisine, the incidence is expected to increase, and pathologists should be familiar with this disease.

    Ureteral obstruction secondary to an inguinal hernia with transplant ureteral component is an extremely rare entity with only several case reports found in literature. In all previously reported cases, management of the obstruction involved temporary drainage with ureteral stenting or nephrostomy tube placements followed by delayed definitive repair. We present two case reports, here one being the first one managed by immediate definitive repair via ureteral reimplant and herniorrhaphy and a second case by delayed definitive repair after percutaneous nephrostomy tube placement. Both patients continued to do well postoperatively with normalization of renal function on follow-up. PMID:27144049

    Biliopancreatic limb obstruction in Roux-en-Y gastric bypass is an infrequent complication that should be recognized early to avoid the risk of peritonitis and death. In this manuscript, we report a case of acute gastric remnant dilatation secondary to intraabdominal hematoma provoked by trocar injury that was compressing the second portion of duodenum lumen. To treat this problem, we decided on a less invasive treatment consisting of percutaneous decompression of the stomach. The procedure was performed using sonographic guidance with local anesthesia, thus, avoiding a new surgical procedure. In this selected case, percutaneous radiological catheter placement provided an effective decompression of the excluded gastric remnant until spontaneous resolution of the obstruction.

  18. Asthma and chronic obstructive pulmonary disease overlap: asthmatic chronic obstructive pulmonary disease or chronic obstructive asthma?

    PubMed

    2016-02-01

    Asthma and chronic obstructive pulmonary disease (COPD) are different disease entities. They are both clinical diagnoses, with diagnostic tools to discriminate between one another. However, especially in older patients (>55 years) it seems more difficult to differentiate between asthma and COPD. This has led to the definition of a new phenotype called asthma COPD overlap syndrome (ACOS). However, our understanding of ACOS is at a very preliminary stage, as most research has involved subjects with existing diagnoses of asthma or COPD from studies with different definitions for ACOS. This has led to different and sometimes opposing results between studies on several features of ACOS, also depending on the comparison with COPD alone, asthma alone or both, which are summarized in this review.We suggest not using the term ACOS for a patient with features of both asthma and COPD, but to describe a patient with chronic obstructive airway disease as completely as possible, with regard to characteristics that determine treatment response (e.g. eosinophilic inflammation) and prognosis (such as smoking status, exacerbation rate, fixed airflow limitation, hyperresponsiveness, comorbidities). This will provide a far more clinically relevant diagnosis, and would aid in research on treatment in more homogenous groups of patients with chronic airways obstruction. More research is certainly needed to develop more evidence-based definitions for this patient group and to evaluate biomarkers, which will help to further classify these patients, treat them more adequately and unravel the underlying pathophysiological mechanism.

    Abstract Background: Transcaval inferior vena cava (IVC) filter penetration involving the urinary tract is rare, but has been previously reported. We herein present unique management of symptomatic hydronephrosis secondary to erosion of an IVC filter limb into the lumen of the proximal right ureter. Case Presentation: A 59-year-old woman presented with abdominal and right flank pain in October 2015 and was found to have right hydronephrosis, apparently secondary to obstruction from erosion of an IVC filter limb into the proximal right ureter. This was effectively managed with percutaneous, endovascular, and endourologic procedures, without the need for a major invasive surgical procedure. Conclusion: Endovascular removal of the IVC filter was performed safely in this case and can be considered when the urinary tract is involved in filter erosion. PMID:27579443

    There is a close relationship between the human host and the intestinal microbiota, which is an assortment of microorganisms, protecting the intestine against colonization by exogenous pathogens. Moreover, the intestinal microbiota play a critical role in providing nutrition and the modulation of host immune homeostasis. Recent reports indicate that some strains of intestinal bacteria are responsible for intestinal ulceration and chronic inflammation in inflammatory bowel diseases (IBD) such as ulcerative colitis (UC) and Crohn's disease (CD). Understanding the interaction of the intestinal microbiota with pathogens and the human host might provide new strategies treating patients with IBD. This review focuses on the important role that the intestinal microbiota plays in maintaining innate immunity in the pathogenesis and etiology of UC and discusses new antibiotic therapies targeting the intestinal microbiota.

    141 children with different kinds of intestinal enzymopathy were examined; of these, 33 had celiac disease, 39--the syndrome of celiac disease, 12--congenital lactase deficiency and 57--the syndrome of disaccharidase insufficiency. In these patients a significant decrease in the average characteristics of the main protective flora and the growth of hemolytic and lactose-negative enterobacteria were established. In all groups of patients increased amounts of Proteus were detected, which was indicative of profound dysbiosis. The content of bifidobacteria was found to be decreased in 89.5-97% of the patients and the content of lactic acid bacteria, in 15.8-33.3%. The decreased content of Escherichia coli with normal enzymatic activity (less than 10(7) colony-forming units) was noted in one-third of the patients with the syndrome of celiac disease and congenital lactase deficiency, in about a half of the patients with the syndrome of disaccharidase insufficiency and least of all in patients with celiac disease (9.1%). The association of opportunistic microbes was detected in 15.6% of the patients, more often in those with celiac disease, the syndrome of celiac disease and congenital lactase deficiency. The severity of disturbances in intestinal eubiosis was found to depend on the gravity of the patients' state.

    Aim: To evaluate the results of the use of the T-tube ileostomy in neonatal intestinal surgery cases. Materials and Methods: A retrospective review of sixty two neonates underwent intestinal obstruction surgery by using T-tube ileostomy was conducted between January 1990 and January 2013.The pathologies of the intestinal obstruction were; thirty four of jejunoileal atresia cases, thirteen case meconium ileus, eight cases perforated necrotizing enterocolitis (NEC), three cases meconium peritonitis, three cases with bowel resection due to intestinal volvulus, and one case of gastroschisis. Results: Mean duration of T-tube placement was 13 days (range9-20days) and the sites of T-tube insertion closed spontaneously in 2 days (range 1-4 days). The mean duration for starting oral intake postoperatively in these patients was 9 days (6-16 days). All patients well tolerated the procedure and there were no serious complications related to the T-tube insertion. However, four patients died due to other reasons like sepsis, respiratory failure and prematurity. Conclusion: T-tube enterostomy is an effective and safe technique for treatment of selected cases of neonatal intestinal surgery. It showed less morbidity and mortality rates than the conventional stoma. Therefore, it is considered a helpful approach in cases where there is danger of hypoperistaltic dilated bowel proximal to the anastomosis.

    Bowel obstruction is the most common abdominal emergency in newborns. Managing bowel obstruction is a challenge for both clinicians and radiologists. The clinical presentation is nonspecific, and both the diagnosis and subsequent management are based on imaging studies. The traditional approach to studying obstructed newborns consists of plain-film abdominal X-rays and contrast-based studies of the gastrointestinal tract. Ultrasonography has proven useful in bowel obstruction, thus avoiding the use of ionizing radiation in certain cases, so diagnostic strategies should include it as a first-line technique. Using an appropriate combination of these techniques, it is possible to reach an accurate diagnosis quickly, orienting treatment and decreasing complications.

    Situs ambiguus is a rare lateralization anomaly that is frequently associated with other malformations, including preduodenal portal vein (PDPV), intestinal malrotation, and cardiovascular anomalies. This is a case report on a newborn that was clinically diagnosed with situs ambiguus and midgut volvulus. During surgery the patient was found to have intestinal malrotation, Meckel's diverticulum, and PDPV that was not a direct cause of duodenal obstruction. The patient was treated with Ladd's procedure and resection of Meckel's diverticulum. It is important to be familiar with the spectrum of situs anomalies to prevent trauma to the portal vein with serious complications during surgery.

    Introduction Multidetector Computed Tomography (MDCT) provides clinically and surgically important information in bowel obstruction. It can depict the severity, level and cause of obstruction. Aim To depict the spectrum of MDCT findings in cases of small and large bowel obstruction. Materials and Methods Contrast enhanced MDCT examination of 50 patients were retrospectively included in the study who had evidence of clinical as well as MDCT evidence of bowel obstruction and in whom surgical/clinical follow-up for final diagnosis was available. CT scan was done in all the patients with Ingenuity CT (128 slice MDCT, Philips Medical Systems). The axial sections were reconstructed in coronal and sagital planes to determine site and cause of bowel obstruction. Results There were 34 males and 16 females patients in this study with mean age of 28.4 years. The level of obstruction was in small bowel in 39 patients (76.67%) and large bowel in 11 patients (23.33%). Adhesive bands were the cause of Small Bowel Obstruction (SBO) in 17 patients (43.5% of SBO patients). The most common CT signs in adhesive band SBO were beak sign (seen in 70.6% patients) and fat notch sign (52.9% patients). Five cases of SBO were secondary to benign stricture. Matted adhesions were the cause of obstruction in 3 patients. All these patients showed transition zone in pelvis with positive small bowel faeces sign. Two patients with SBO due to adhesive band had evidence of closed loop obstruction with evidence of gangrenous gut on surgery. Large Bowel Obstruction (LBO) was seen in 11 patients. Most common cause of LBO was primary colonic malignancy, accounting for 7 patients (63.6%). In one patient, the cause was direct invasion of hepatic flexure by carcinoma of gall bladder. Other causes of LBO were pelvic adhesions, faecal impaction and ischaemic stricture. Conclusion SBO is more common than LBO with adhesive bands being the most common cause of SBO. MDCT is very useful for depicting site and cause

  11. Hypokalemia associated with acute colonic pseudo-obstruction in an ESRD patient.

    PubMed

    Boobés, Khaled; Rosa, Robert M; Batlle, Daniel

    2017-03-01

    Ogilvie's syndrome, or acute colonic pseudo-obstruction, is characterized by massive dilation of the colon without mechanical obstruction. Water and electrolytes often can be sequestered in the dilated intestinal loops resulting in profuse and watery diarrhea as well as hypokalemia. We report an anuric, end-stage renal disease (ESRD) patient undergoing peritoneal dialysis (PD) who developed acute colonic pseudo-obstruction causing a prolonged hospitalization. He also developed severe hypokalemia with a serum potassium (K+) as low as 2.4 mEq/L and required 180 - 240 mEq of potassium chloride per day for more than a month to correct it. While PD K+ losses often contribute to hypokalemia, the PD K+ loss was estimated to be only 39 mEq/day. Therefore, PD could only contribute modestly to the recalcitrant hypokalemia observed during the episode of pseudo-obstruction. It has been shown, however, that patients with colonic pseudo-obstruction have enhanced colonic K+ secretion. In addition, experimental studies in patients with chronic kidney disease (CKD) have demonstrated that colonic K+ excretion can be up to 3 times greater than in individuals with normal renal function. This increase may involve an upregulation of the large conductance K+ channel (maxi-K), also known as the BK channel, in the apical border of the colonocytes. We suggest that ESRD may have placed our patient at a greater risk of developing hypokalemia as his colon may have already adapted to secrete more K+. Clinicians should be aware of this extrarenal K+ wasting etiology in patients with colonic pseudo-obstruction, particularly in those with CKD where such a severe K+ deficit is not anticipated and, therefore, may inhibit more rigorous K+ replacement.

    Obstruction of bile flow results in bacterial proliferation and mucosal injury in the small intestine that can lead to the translocation of bacteria across the epithelial barrier and systemic infection. These adverse effects of biliary obstruction can be inhibited by administration of bile acids. Here we show that the farnesoid X receptor (FXR), a nuclear receptor for bile acids, induces genes involved in enteroprotection and inhibits bacterial overgrowth and mucosal injury in ileum caused by bile duct ligation. Mice lacking FXR have increased ileal levels of bacteria and a compromised epithelial barrier. These findings reveal a central role for FXR in protecting the distal small intestine from bacterial invasion and suggest that FXR agonists may prevent epithelial deterioration and bacterial translocation in patients with impaired bile flow.

    Abstract According to traditional Chinese medicine (TCM) theory, a specific physiological and pathological relationship exists between the lungs and the large intestine. The aim of this study is to delineate the association of chronic obstructive pulmonary disease (COPD) and hemorrhoids in order to verify the “interior–exterior” relationship between the lungs and the large intestine. A retrospective cohort study is conceived from the National Health Insurance Research Database, Taiwan. The 2 samples (COPD cohort and non-COPD cohort) were selected from the 2000 to 2003 beneficiaries of the NHI, representing patients age 20 and older in Taiwan, with the follow-up ending on December 31, 2011. The COPD cohort (n = 51,506) includes every patient newly diagnosed as having Chronic Obstructive Pulmonary Disease (COPD, ICD-9-CM: 490–492, 494, 496), who have made at least 2 confirmed visits to the hospital/clinic. The non-COPD cohort (n = 103,012) includes patients without COPD and is selected via a 1:2 (COPD: non-COPD) matching by age group (per 5 years), gender, and index date (diagnosis date of COPD for the COPD cohort). Compared with non-COPD cohorts, patients with COPD have a higher likelihood of having hemorrhoids and the age-, gender- and comorbidies-adjusted hazard ratio (HR) for hemorrhoids is 1.56 (95% confidence intervals [CI]:1.50–1.62). The adjusted HR of hemorrhoids for females is 0.79 (95% CI: 0.77–0.83), which is significantly less than that for males. The elderly groups, 40 to 59 years and aged 60 or above, have higher adjusted HRs than younger age groups (20–39 years), 1.19 (95% CI: 1.14–1.26), and 1.18 (95% CI: 1.12–1.24), respectively. Patients with COPD may have a higher likelihood to have hemorrhoids in this retrospective cohort study. This study verifies the fundamental theorem of TCM that there is a definite pathogenic association between the lungs and large intestine. PMID:28272246

    Antibiotic treatments have been used to modulate intestinal bacteria and investigate the role of intestinal bacteria on bile acid (BA) homeostasis. However, knowledge on which intestinal bacteria and bile acids are modified by antibiotics is limited. In the present study, mice were administered various antibiotics, 47 of the most abundant bacterial species in intestine, as well as individual BAs in plasma, liver, and intestine were quantified. Compared to the two antibiotic combinations (vancomycin + imipenem and cephalothin + neomycin), the three single antibiotics (metronidazole, ciprofloxacin and aztreonam) have less effect on intestinal bacterial profiles, and thus on host BA profiles and mRNA expression of genes that are important for BA homeostasis. The two antibiotic combinations decreased the ratio of Firmicutes to Bacteroidetes in intestine, as well as most secondary BAs in serum, liver and intestine. Additionally, the two antibiotic combinations significantly increased mRNA of the hepatic BA uptake transporters (Ntcp and Oatp1b2) and canalicular BA efflux transporters (Bsep and Mrp2), but decreased mRNA of the hepatic BA synthetic enzyme Cyp8b1, suggesting an elevated enterohepatic circulation of BAs. Interestingly, the two antibiotic combinations tended to have opposite effect on the mRNAs of most intestinal genes, which tended to be inhibited by vancomycin + imipenem but stimulated by cephalothin + neomycin. To conclude, the present study clearly shows that various antibiotics have distinct effects on modulating intestinal bacteria and host BA metabolism. - Highlights: • Various antibiotics have different effects on intestinal bacteria. • Antibiotics alter bile acid composition in mouse liver and intestine. • Antibiotics influence genes involved in bile acid homeostasis. • Clostridia appear to be important for secondary bile acid formation.

    We report a case of a post-tracheotomy suprastomal granuloma in the early postoperative phase that caused subacute airway obstruction in a 28-year-old woman. The patient had undergone the tracheotomy during the surgical treatment of a submental abscess. During recovery, several capping trials had failed. Therefore, direct laryngoscopy was performed on postoperative day 11, and it revealed that the airway was being obstructed by a tracheal granuloma. The granuloma was managed with a partial resection and corticosteroids. The patient was successfully decannulated with no recurrence of the granuloma. To the best of our knowledge, airway obstruction secondary to a tracheal granuloma has not been previously reported as an early complication of a traditional surgical tracheotomy in an adult. In this report, we discuss the presenting features of this case and we propose several possible etiologies.

  16. Stenting of vertical vein in an infant with obstructed supracardiac total anomalous pulmonary venous drainage

    2016-01-01

    A 1.7 kg infant with obstructed supracardiac total anomalous pulmonary venous drainage (TAPVD) presented with severe pulmonary hypertension secondary to vertical vein obstruction. The child, in addition, had a large omphalocele that was being managed conservatively. The combination of low weight, unoperated omphalocele, and severe pulmonary hypertension made corrective cardiac surgery very high-risk. Therefore, transcatheter stenting of the stenotic vertical vein, as a bridge to corrective surgery was carried out. The procedure was carried out through the right internal jugular vein (RIJ). The stenotic segment of the vertical vein was stented using a coronary stent. After procedure, the child was discharged well to the referred hospital for weight gain and spontaneous epithelialization of the omphalocele. Stenting of the vertical vein through the internal jugular vein can be considered in very small neonates as a bridge to repair obstructed supracardiac total anomalous venous drainage. PMID:27212859

  17. Phytobezoar-induced small bowel obstruction associated with a concomitant gastric phytobezoar and ulcer in an elderly woman.

    Bezoars are aggregates of indigested foreign material that accumulate in the gastroenteric tract, expecially in the stomach and in the narrowest points of the small bowel. They often occur in subjects who follow a diet rich in fruit and vegetables and in those one who previously underwent gastric resective surgery for peptic ulcer. Bezoar formation has even been observed in case of reduced gastric motility and secretion due to diabetes, hypothyroidism, pernicious anemia, myotonic syndromes, and Guillain-Barré syndrome. As they are an uncommon cause of small bowel obstruction, phytobezoars are often not considered in the differential diagnosis of occlusive intestinal syndromes and so frequently come as an intraoperative finding. A consequence of this missed diagnosis in the preoperative period is an unnecessary diagnostic delay that can significantly increase morbidity and mortality. This case report illustrates the need to include phytobezoars in the preoperative diagnostic workout of intestinal obstruction in order to rule out the presence of multiple bezoars and prevent recurrent obstruction. Now that phytobezoars are becoming a less infrequent cause of small bowel obstruction than previously thought, such a diagnostic possibility should always be considered.

    Echinostoma caproni is an intestinal trematode that has been extensively used as an experimental model to investigate the factors determining the resistance to intestinal helminths or the development of chronic infections. ICR mice are permissive hosts for E. caproni in which chronic infections are developed, concomitantly with local Th1 responses, elevated levels of local IFN-γ, inflammation and antibody responses. However, mice develop partial resistance to homologous challenge infections after cure of a primary infection, which converts this subject into an adequate model for the study of the mechanisms generating resistance against intestinal helminths. The purpose of the present study was to compare the immune response induced in primary and secondary infections to elucidate the factors determining the different outcome of the infection in each type of infection. The results obtained indicate that susceptibility is determined by the lack of IL-25 expression in response to primary infection. In contrast, infection in an environment with elevated levels of IL-25, as occurs in challenge infection, results in a Th2 phenotype impairing parasite survival. This was confirmed by treatment of naïve mice with exogenous IL-25 and subsequent infection. Changes induced in goblet cell populations and mucin glycosylation could be implicated in resistance to infection. PMID:27658962

    Objective: We investigated the effect of xuesaitong on intestinal barrier dysfunction and related mechanisms in a rat model for intestinal ischemia-reperfusion. Methods: Rats were divided into sham-operated, disease-model and Xuesaitong-treated groups. In the disease-model and Xuesaitong-treated rats an intestinal ischemia-reperfusion injury (IRI) model was introduced, which was created by a temporary obstruction of the superior mesenteric artery (SMA). The xuesaitong group was pre-treated with injections into the abdominal cavity prior to the generation of the IRI model. Tissue changes were evaluated using H&E staining and electron microscopy. Samples were analyzed at 0, 3 and 24 h post IRI. Ascites volumes as well as small intestinal mucosa bleeding, injury scores, wet to dry weight ratios, and propulsions were evaluated. Apoptotic rates were determined with TUNNEL assays. Blood serum tumor necrosis factor-α (TNF-α) levels were measured using ELISA, and Bcl-2 and caspase-3 expression in small intestinal mucosa measured using immunohistochemistry. Results: We determined a significant increase of pathological damage to small intestinal tissues, intestinal wet to dry ratios, ascites volume, TNF-α levels, apoptosis rates of small intestinal mucosa, and expression of Bcl-2 and caspase-3 proteins in the disease-model group compared to the sham-operated group (P < 0.001), and intestinal motility was significantly decreased (P < 0.001). However, comparisons between disease-model and xuesaitong pre-treated animals revealed, that in the treatment group these changes occurred in significant less severities. Conclusions: Xuesaitong can effectively alleviate intestinal barrier dysfunction caused by ischemia-reperfusion injury by reducing TNF-α, up-regulating Bcl-2 and down-regulating caspase-3 expression, in addition to increasing peristalsis.

    SUMMARY Secondary osteoporosis is less common than primary osteoporosis. It may be suspected in patients who present with a fragility fracture despite having no risk factors for osteoporosis. In addition, secondary osteoporosis should be considered if the bone density Z-score is –2.5 or less. Consider the fracture site and presence of other clinical clues to guide investigations for an underlying cause. The tests to use are those that are indicated for the suspected cause. Baseline investigations include tests for bone and mineral metabolism (calcium, phosphate, alkaline phosphatase, 25-hydroxyvitamin D, parathyroid hormone), liver and kidney function, full blood count and thyroid-stimulating hormone. More detailed testing may be required in patients with severe osteoporosis. PMID:27346916

    The authors report a retrospective study of 10 cases of gastric and small bowel bezoars. There was one gastric trichobezoar diagnosed by an abdominal mass and 9 small bowel obstruction due to phytobezoars. All patients underwent surgery: the gastric trichobezoar was removed through a gastrotomy; small bowel bezoars were treated either by enterotomy (n = 3), fragmentation (n = 5) or bowel resection (n = 1). Non operative treatment is efficient in gastric phytobezoars. Surgery is advisable for trichobezoars and small bowel bezoars. Prevention is main and patients who have gastric surgery must be alarmed from consumption of cactus in our country Tunisia.

  16. Unusual intestinal talcosis.

    Anani, P A; Ribaux, C; Gardiol, D

    1987-11-01

    A case of intestinal talcosis in a 46-year-old man is reported. At the age of 27, the patient was treated for pulmonary tuberculosis with tablets containing talc (183 g talc per 2,670 g total drug intake) over a period of 28 months. Eighteen years later, the patient was hospitalized for abdominal pain that remained refractory to antacids; he subsequently underwent a right hemicolectomy. Light-microscopic examination revealed a prominent fibrosis of the intestinal wall in which birefringent particles were demonstrated by polarized light. Using energy-dispersive spectroscopy, an analysis of these particles showed that they were predominantly composed of silicon and magnesium as well as small amounts of phosphorus, sulphur, calcium, and iron--the spectrum typically associated with talc. We believe that the source of this talc is the tablets ingested by the patient during prior antituberculosis therapy.

    Acute colonic obstruction due to malignancies is an emergency that requires surgical treatment. Elderly patients or inoperable tumors require intestinal decompression that is a simple colostomy in almost all cases. This “manoeuvre” leads the patient to a percentage of mortality/morbidity and to a bad quality of life due to acceptance of stoma. The introduction of enteral metal stent inserted endoscopically has, in our opinion, provided a new way to obtaining the definitive palliation of inoperable colo-rectal cancer with a simple method. We reported our case-series and we analyzed the current literature and costs of treatments. PMID:14991956

    It was performed comparative analysis of results of reconstructive operations in 116 patients with terminal colostomy after urgent obstructive resection of colon. Damage of reconstructive operations which differ by only access was estimated. Midline access was used in 49 patients, parastomal - in 51 cases. Laparoscopic operation was applied in 16 patients. The most traumatic method was middle laparotomy for restoration of colonic integrity. Laparoscopic operations and parastomal access are less invasive. Laparoscopic operations are accompanied by longer duration, greater blood loss and later restoration of intestinal motility pattern in comparison with surgery through parastomal access. It is associated with duration and damage of adhesiotomy stage.

  19. Elenoside increases intestinal motility

    AIM: To study the effects of elenoside, an arylnaph-thalene lignan from Justicia hyssopifolia, on gastro-intestinal motility in vivo and in vitro in rats. METHODS: Routine in vivo experimental assessments were catharsis index, water percentage of boluses, intestinal transit, and codeine antagonism. The groups included were vehicle control (propylene glycol-ethanol-plant oil-tween 80), elenoside (i.p. 25 and 50 mg/kg), cisapride (i.p. 10 mg/kg), and codeine phosphate (intragastric route, 50 mg/kg). In vitro approaches used isolated rat intestinal tissues (duodenum, jejunum, and ileum). The effects of elenoside at concentrations of 3.2 x 10-4, 6.4 x 10-4 and 1.2 x 10-3 mol/L, and cisapride at 10-6 mol/L were investigated. RESULTS: Elenoside in vivo produced an increase in the catharsis index and water percentage of boluses and in the percentage of distance traveled by a suspension of activated charcoal. Codeine phosphate antagonized the effect of 25 mg/kg of elenoside. In vitro, elenoside in duodenum, jejunum and ileum produced an initial decrease in the contraction force followed by an increase. Elenoside resulted in decreased intestinal frequency in duodenum, jejunum, and ileum. The in vitro and in vivo effects of elenoside were similar to those produced by cisapride. CONCLUSION: Elenoside is a lignan with an action similar to that of purgative and prokinetics drugs. Elenoside, could be an alternative to cisapride in treatment of gastrointestinal diseases as well as a preventive therapy for the undesirable gastrointestinal effects produced by opioids used for mild to moderate pain.

  20. The allometry of rodent intestines.

    PubMed

    Lovegrove, Barry G

    2010-06-01

    This study examined the allometry of the small intestine, caecum, colon and large intestine of rodents (n = 51) using a phylogenetically informed approach. Strong phylogenetic signal was detected in the data for the caecum, colon and large intestine, but not for the small intestine. Most of the phylogenetic signal could be attributed to clade effects associated with herbivorous versus omnivorous rodents. The herbivorous rodents have longer caecums, colons and large intestines, but their small intestines, with the exception of the desert otomyine rodents, are no different to those of omnivorous rodents. Desert otomyine rodents have significantly shorter small intestines than all other rodents, reflecting a possible habitat effect and providing a partial explanation for the low basal metabolic rates of small desert mammals. However, the desert otomyines do not have shorter colons or large intestines, challenging claims for adaptation to water retention in arid environments. Data for the Arvicolidae revealed significantly larger caecums and colons, and hence longer large intestines, with no compensatory reduction in the length of the small intestine, which may explain how the smallest mammalian herbivores manage to meet the demands of a very high mass-specific metabolic rate. This study provides phylogenetically corrected allometries suitable for future prediction testing.

    Purpose The purpose of this study was to determine if there is an association between obstructive sleep apnea (OSA) and central serous chorioretinopathy (CSCR). Methods Patients with CSCR without a history of steroid use or secondary retinal disease were matched based on age/gender/body mass index with control patients and administered the Berlin Questionnaire to assess for OSA risk. Patients were scored “OSA+” if they were at “high risk” on the Berlin Questionnaire or reported a previous OSA diagnosis. Rates of OSA+ were compared between the 2 groups, odds ratio and its 95% confidence interval was calculated using exact conditional logistic regression. Results Forty-eight qualifying patients with CSCR were identified. There were no statistically significant differences between the CSCR and control groups by age (mean = 55 years), gender (79% male), body mass index (mean = 28.2), history of diabetes, or hypertension. Within the CSCR group, 22 patients (45.8%) were OSA+ versus 21 control patients (43.8%) (difference = 2.1%; 95% confidence interval, −18.2% to 22.2%; exact odds ratio = 1.08, 95% confidence interval, 0.47–2.49; P = 1.00). Conclusion When compared with matched controls, patients with CSCR did not have statistically significant higher rates of OSA risk or previous diagnosis. This finding contrasts with previous work showing a strong association between the diseases. The divergence is likely due to our matching controls for body mass index, a significant risk factor for OSA. PMID:25127049

    Alcohol abuse is a significant contributor to the global burden of disease and can lead to tissue damage and organ dysfunction in a subset of alcoholics. However, a subset of alcoholics without any of these predisposing factors can develop alcohol-mediated organ injury. The gastrointestinal tract (GI) could be an important source of inflammation in alcohol-mediated organ damage. The purpose of review was to evaluate mechanisms of alcohol-induced endotoxemia (including dysbiosis and gut leakiness), and highlight the predisposing factors for alcohol-induced dysbiosis and gut leakiness to endotoxins. Barriers, including immunologic, physical, and biochemical can regulate the passage of toxins into the portal and systemic circulation. In addition, a host of environmental interactions including those influenced by circadian rhythms can impact alcohol-induced organ pathology. There appears to be a role for therapeutic measures to mitigate alcohol-induced organ damage by normalizing intestinal dysbiosis and/or improving intestinal barrier integrity. Ultimately, the inflammatory process that drives progression into organ damage from alcohol appears to be multifactorial. Understanding the role of the intestine in the pathogenesis of alcoholic liver disease can pose further avenues for pathogenic and treatment approaches. PMID:26501334

    Despite significant conservation intervention, the kiwi (Apteryx spp.) is in serious population decline. To increase survival in the wild, conservation management includes rearing of young birds in captivity, safe from introduced mammalian predators. However, an increase in density of immunologically naïve kiwi increases the risk of exposure to disease, including coccidia. Intestinal coccidiosis has recently been described in the kiwi, and although extra-intestinal coccidiosis was first recognized in kiwi in 1978, very little is known about this disease entity. This study used archived histological tissues and reports from routine necropsies to describe the pathology of naturally occurring extra-intestinal coccidiosis. At least 4.5% of all kiwi necropsied during 1991 to 2011 (n=558) were affected by extra-intestinal coccidiosis, and it is estimated that it caused death in 0.9 to 1.2% of kiwi in the study group. Four forms were recognized: renal, hepatic, and, less commonly, splenic and pulmonary. At necropsy, renal coccidiosis was associated with miliary white streaks and foci through the kidneys, renomegaly, and renal pallor or congestion. Renal meronts and gametocytes were confined to the distal convoluted tubules and collecting ducts, and were associated with renal tubular necrosis and tubular obstruction. Hepatic miliary pinpoint foci were present throughout the hepatic parenchyma associated microscopically with macromeronts measuring 304×227 µm. In two cases, clusters of splenic meronts were identified, and a similar lesion was identified in the pulmonary interstitium of another case. Juvenile, captive kiwi were most often affected with extra-intestinal coccidiosis, illustrating an increased expression of disease with population manipulation for conservation purposes.

    Secondary hyperoxaluria is due either to increased intestinal oxalate absorption or to excessive dietary oxalate intake. Certain intestinal diseases like short bowel syndrome, chronic inflammatory bowel disease or cystic fibrosis and other malabsorption syndromes are known to increase the risk of secondary hyperoxaluria. Although the urinary oxalate excretion is usually lower than in primary hyperoxaluria, it may still lead to significant morbidity by recurrent urolithiasis or progressive nephrocalcinosis. A clear distinction between primary and secondary hyperoxalurias is important. As correct classification may be difficult, appropriate diagnostic tools are needed to delineate the metabolic background as a basis for optimal treatment. We developed an individual approach for the evaluation of patients with suspected secondary hyperoxaluria. First, 24 h urines are examined repeatedly for lithogenic (e.g. calcium, oxalate, uric acid) and stone-inhibitory (e.g. citrate, magnesium) substances, and the patients are asked to fill in a dietary survey form. Urinary saturation is calculated using the computer based program EQUIL2, and the BONN-Risk-index is determined. The measurement of plasma oxalate and of urinary glycolate helps to distinguish between primary and secondary hyperoxalurias. If secondary hyperoxaluria is suspected, the stool is examined for Oxalobacter formigenes, an intestinal oxalate degrading bacterium, as lack or absence may lead to increased intestinal oxalate absorption. The last diagnostic step is to study the intestinal oxalate absorption using [13C2]oxalate. Depending on the results, various therapeutic options are available: 1) a diet low in oxalate, but normal or high in calcium, 2) a high fluid intake (>1.5 L/m2/d), 3) medications to increase the urinary solubility, 4) specific therapeutic measures in patients with malabsorption syndromes, depending on the underlying pathology, and 5) intestinal recolonization of Oxalobacter formigenes or the

    Obstructive Sleep Apnoea (OSA) has recently been reported to be a cause of chronic cough. It should be considered when cough remains unexplained following investigations and treatments for common causes. The presence of nocturnal cough, snoring and gastro-oesophageal reflux may be helpful in identifying patients who require further investigation. Daytime somnolence is often absent. Continuous positive airway pressure (CPAP) therapy has been reported to be effective in alleviating cough. Therapy for gastro-oesophageal reflux disease, if present, should be optimised. The mechanism of the association between OSA and cough is not clear, but airway inflammation, gastro-oesophageal reflux disease, increased cough reflex sensitivity and tracheobronchomalacia are possible explanations. Further studies should identify clinical predictors of OSA-cough, establish mechanisms and the optimal therapy.

    One of the most common symptoms of obstructive sleep apnea syndrome (OSAS) is daytime drowsiness. It is associated with a high cardiovascular morbidity and mortality, and an elevated incidence of car crashes. In general, young patients don't want conservative treatment because symptomatic and to prevent secondary effects. In this article, we briefly define sleep disorders and the interest of cephalometric examination. We describe the different treatment possibilities and stress the important role of orthognathic surgery in this syndrome.

    A pericecal hernia is a type of internal hernia, which rarely causes small bowel obstruction (SBO). At our institution, a 92-year-old man presented with vomiting and abdominal pain. He was conservatively treated with a diagnosis of SBO. After 2 weeks of copious drainage output, he was taken to the operating room. Laparoscopy revealed a pericecal hernia that was successfully reduced. We conclude that laparoscopic surgery is an effective way to treat SBOs secondary to pericecal hernias. PMID:26933000

    Asthma bronchiale and chronic obstructive pulmonary disease are the most prevalent lung diseases characterized by inflammation of the airways. International and Hungarian guidelines provide proper definitions for clinical symptoms, diagnostics and therapy of both diseases. However, in everyday clinical practice, overlap of asthma and chronic obstructive pulmonary disease has become more frequent. As guidelines are mainly based on large, multicenter, randomized, controlled trials that exclude overlap patients, there is a lack of diagnostic and especially therapeutic strategies for these patients. This review summarizes clinical characteristics of asthma and chronic obstructive pulmonary disease overlap, and provides daily practical examples for its management.

    The impairment of intestinal motility and related infectious complications are the predominant clinical phenomenon in patients with severe acute pancreatitis (SAP). We aimed to investigate the effects of Da-Cheng-Qi decoction (DCQD) on the gastrointestinal injury in SAP patients and the potential mechanism involved in rats. DCQD was enema administered to 70 patients for 7 days in West China Hospital. Mortality and organ failure during admission were observed and blood samples for laboratory analysis were collected. We also experimentally examined plasma inflammatory cytokines in rat serum and carried the morphometric studies of the gut. Intestinal propulsion index and serum and tissue vasoactive intestinal peptide (VIP) were also detected. Though DCQD did not affect the overall incidence of organ failure, it shortened the average time of paralytic intestinal obstruction and decreased the morbidity of infectious complications in patients with SAP. Compared with untreated rats, the DCQD lowered the levels of proinflammatory cytokine and decreased the mean pathological intestinal lesion scores. The VIP level in intestinal tissue or serum in DCQD group was obviously lowered and intestinal propulsion index was significantly improved. In conclusion, DCQD has good effect on pancreatitis-associated intestinal dysmotility in patients and in rat models.

    Gastric outlet obstruction (GOO) presenting beyond the newborn period is a relatively rare condition, when infantile hypertrophic pyloric stenosis (IHPS) is excluded. This report describes the clinical features, evaluation and management of 18 patients with GOO which was not caused by IHPS. The sex, age, and main presenting features were recorded on admission. Hemoglobin estimation, serum chemistry and blood gas analysis were also assessed in these patients. The diagnosis was confirmed with gastrointestinal barium, B ultrasound, gastroscopy, or at surgery. Some of them underwent gastroscopy with biopsy sampling for rapid urease test or histologic examination with Giemsa stains for Helicobacter pylori. Thirteen patients had peptic ulcer disease, of which six were successfully treated with medications. While the other seven needed operative management which included Heineke-Mikulicz pyloroplasty, gastroduodenostomy or gastrojejunostomy, respectively. All the patients who had Heineke-Mikulicz pyloroplasty or gastrojejunostomy developed bile reflux gastritis that could be alleviated with omeprazol. None of the patients developed dumping syndrome, failing to thrive, or anemia. Three children with antral diaphragm recovered without any complications by diaphragm excision with Heineke-Mikulicz pyloroplasty. The pylorus was compressed by fibrotic band in one 30-month boy, and he recovered uneventfully with Heineke-Mikulicz pyloroplasty during 10-year follow-up. Gastric outlet obstruction secondary to ingestion of sulfuric acid was noted in one patient, and he was successfully treated with gastroduodenostomy. Our data suggests that the satisfactory results could be expected in children with GOO with different therapeutic modalities based on the specific cause and degree of obstruction.

    With the high prevalence of gastrointestinal disorders, there is great interest in establishing in vitro models of human intestinal disease and in developing drug-screening platforms that more accurately represent the complex physiology of the intestine. We will review how recent advances in developmental and stem cell biology have made it possible to generate complex, three-dimensional, human intestinal tissues in vitro through directed differentiation of human pluripotent stem cells. These are currently being used to study human development, genetic forms of disease, intestinal pathogens, metabolic disease and cancer. PMID:24496613

    Phytobezoar is an unusual cause of small bowel obstruction. It accounts for about 0.4%-4% of all mechanical bowel obstruction. However, the symptoms are not very different from those caused by usual aetiologies of small bowel obstruction. The commonest site of obstruction is terminal ileum. Treatment of small bowel obstruction due to Phytobezoar is surgery. Prevention includes avoidance of high fibre diet, prokinetics particularly in patients who have undergone gastric surgery. A 57-year-old male presented with symptoms and signs of small bowel obstruction. On exploratory laparotomy Phytobezoar in the ileum was found to be the cause of obstruction. Diagnosis was confirmed by histopathology.

    Objectives The m.3243A>G MTTL1 mutation is the most common cause of mitochondrial disease; yet there is limited awareness of intestinal pseudo‐obstruction (IPO) in this disorder. We aimed to determine the prevalence, severity, and clinical outcome of patients with m.3243A>G‐related mitochondrial disease manifesting with IPO. Methods In this large, observational cohort study, we assessed the clinical, molecular, and radiological characteristics of patients with genetically determined m.3243A>G‐related mitochondrial disease, who presented with severe symptoms suggestive of bowel obstruction in the absence of an occluding lesion. Results Between January 2009 and June 2015, 226 patients harbouring the m.3243A>G mutation were recruited to the Medical Research Council Centre Mitochondrial Disease Patient Cohort, Newcastle. Thirty patients (13%) presented acutely with IPO. Thirteen of these patients had a preceding history of stroke‐like episodes, whereas 1 presented 27 years previously with their first stroke‐like episode. Eight patients developed IPO concomitantly during an acute stroke‐like episode. Regression analysis suggested stroke was the strongest predictor for development of IPO, in addition to cardiomyopathy, low body mass index and high urinary mutation load. Poor clinical outcome was observed in 6 patients who underwent surgical procedures. Interpretation Our findings suggest, in this common mitochondrial disease, that IPO is an under‐recognized, often misdiagnosed clinical entity. Poor clinical outcome associated with stroke and acute surgical intervention highlights the importance of the neurologist having a high index of suspicion, particularly in the acute setting, to instigate timely coordination of appropriate care and management with other specialists.

    Infection by Strongyloides stercoralis is a highly prevalent helminthiasis, which is mostly distributed in the tropical and subtropical regions of the world. Although a substantial number of cases are asymptomatic or paucisymtomatic, severe and life-threatening forms of this infection still occur and not infrequently is lately diagnosed. Gram-negative bacteria septicemia, which frequently accompanies the severe helminthiasis, contributes to the high mortality rate. Severe infection is invariably triggered by any imbalance in the host's immunity, favoring the auto-infective cycle, which increases the intraluminal parasite burden enormously. Clinical presentation of severe cases is varied, and diagnosis requires a high suspicion index. Acute abdomen has been reported in association with S. stercoralis infection, but intestinal necrosis is rarely found during the surgical approach. The authors report the case of a man who sought the emergency unit with recent onset abdominal pain. Clinical and imaging features were consistent with obstructive acute abdomen. Scattered adhesions and a necrotic ileal segment with a tiny perforation represented the surgical findings. The patient outcome was unfavorable and respiratory distress required an open lung biopsy. Both surgical specimens showed S. stercoralis infection. Unfortunately the patient underwent multiple organ failure and septicemia, and subsequently died. The authors call attention to the finding of intestinal necrosis and impaired intestinal motility disorder as possibilities for the diagnosis and risk factor, respectively, for a severe infection of S. stercoralis.

    Familial hypertriglyceridaemia is inherited in an autosomal dominant manner. The responsible genetic abnormality is unknown but recently, a novel gene encoding apolipoprotein AV has been linked to familial hypertriglyceridaemia. All patients develop the same phenotype with elevated levels of very low density lipoproteins (VLDL) in plasma. The main disorder of this dyslipidaemia is decreased intestinal absorption of biliary acids, leading to a compensatory increase of VLDL production. In familial hypertriglyceridaemia, a marked increase in plasma triglyceride (TG) levels can cause acute pancreatitis. Moreover, patients with other genetic factors, like familial chylomicronaemia, familial combined hyperlipidaemia, familial dysbetalipoproteinaemia and other rare disorders (e.g. Tangier disease and fish eye disease) may present increase of TG levels or cholesterol levels or both. Secondary hypertriglyceridaemias include hypothyroidism, kidney abnormalities (e.g. nephrotic syndrome or chronic kidney failure), diabetes mellitus, heavy alcohol consumption and obesity. In men and postmenopausal women, it seems that estrogen deficiency is responsible for higher TG levels compared with premenopausal women postprandially. In every state -fasting or postprandial-, women demonstrate lower plasma TG levels compared with men. This fact is due not only to increased muscular TG uptake and storage but also to higher TG clearance. Many studies demonstrated an age impact on plasma TG increase and larger variation of fasting TG levels caused by age. Also, hypertriglyceridaemia (TG >150 mg/dl; 1.7 mmol/l) is one of the diagnostic criteria of metabolic syndrome. Finally, several drugs may increase TG levels (e.g. chlorthalidone or beta-blockers).

    We report a case of catheter obstruction due to complete narrowing of the lumen of a connecting pin, and catheter disconnection in a patient undergoing intrathecal Baclofen pump exchange. The patient underwent intrathecal baclofen pump implantation for treatment of lower extremity spasticity and hypertonia secondary to congenital tetraplegia. Intrathecal baclofen dose escalation occurred over the course of treatment (73 mo) from 80 to 708 mcg/d representing a 189% increase in dose. The pump had neared the manufacturer's recommended exchange interval; therefore, a pump exchange was scheduled to surgically replace the device. One week before surgery, the patient noted a distinct increase in his symptomatology and began enteral baclofen therapy. During the surgery, the pump catheter was noted to be disconnected from the pump. Upon further examination, the lumen of the connection pin positioned between the pump catheter and intrathecal catheter was completely obstructed. Postsurgically, the patient's intrathecal baclofen dose was substantially reduced from 708 to 527 mcg/d (25.6% reduction) to control hypotonicity and to reestablish an Ashworth score of 2. We discuss intrathecal baclofen therapy and a unique complication associated with a catheter connecting pin.

    Purpose: To retrospectively evaluate the clinical effectiveness of a self-expanding uncovered Wallstent in patients with malignant gastroduodenal obstruction. Materials and Methods: Under combined endoscopic and fluoroscopic guidance, 29 patients with a malignant gastroduodenal stenosis were treated with a self-expanding uncovered metallic Wallstent. A dysphagia score was assessed before and after the intervention to measure the success of this palliative therapy. The dysphagia score ranged between grade 0 to grade 4: grade 0 = able to tolerate solid food, grade 1 = able to tolerate soft food, grade 2 = able to tolerate thick liquids, grade 3 = able to tolerate water or clear fluids, and grade 4 = unable to tolerate anything perorally. Stent patency and patients survival rates were calculated. Results: The insertion of the gastroduodenal stent was technically successful in 28 patients (96.5%). After stenting, 25 patients (86.2%) showed clinical improvement by at least one score point. During follow-up, 22 (78.5%) of 28 patients showed no stent occlusion until death and did not have to undergo any further intervention. In six patients (20.6%), all of whom were treated with secondary stent insertions, occlusion with tumor ingrowth and/or overgrowth was observed after the intervention. The median period of primary stent patency in our study was 240 days. Conclusion: Placement of an uncovered Wallstent is clinically effective in patients with malignant gastroduodenal obstruction. Stent placement is associated with high technical success, good palliation effect, and high durability of stent function.

    In vitro intestinal models can provide new insights into small intestinal function, including cellular growth and proliferation mechanisms, drug absorption capabilities, and host-microbial interactions. These models are typically formed with cells cultured on 2D scaffolds or transwell inserts, but it is widely understood that epithelial cells cultured in 3D environments exhibit different phenotypes that are more reflective of native tissue. Our focus was to develop a porous, synthetic 3D tissue scaffold with villous features that could support the culture of epithelial cell types to mimic the natural microenvironment of the small intestine. We demonstrated that our scaffold could support the co-culture of Caco-2 cells with a mucus-producing cell line, HT29-MTX, as well as small intestinal crypts from mice for extended periods. By recreating the surface topography with accurately sized intestinal villi, we enable cellular differentiation along the villous axis in a similar manner to native intestines. In addition, we show that the biochemical microenvironments of the intestine can be further simulated via a combination of apical and basolateral feeding of intestinal cell types cultured on the 3D models.

    The objective of the present investigation is the study and interpretation of the role played by the immunoglobulins, especially IgA, during acute diarrhea in children. IgA, IGG and IgM values in serum and IgA in intestinal secretions were studied in a group of children (between 3 months and 5 years of age) during diarrhea, convalescence and in normals. The method of simple radial immunodiffusion according to Mancini was employed. IgA is the immunoglobulin which suffers the greastest alteration in acute diarrhea. The precipitation halos (the average values), were lower during the diarrhea than in convalescence and in normals.

    Hypertension secondary to hydronephrosis is not commonly reported in the medical literature. Tubuloglomerular feedback and the renin-angiotensin-aldosterone axis are thought to mediate this process. We describe a patient presenting with acute kidney injury and bilateral hydronephrosis secondary to pelvic malignancy in which peripheral venous renin and aldosterone were elevated. Her blood pressure improved rapidly following insertion of bilateral nephrostomies. The speed of resolution of hypertension following relief of obstruction suggests that humorally mediated vasoconstriction can play an important role in the mechanism by which hydronephrosis causes hypertension. We also discuss other causes of renal parenchymal compression that may lead to the development of hypertension.

    H1 antihistamines constitute one of the main references for the treatment of allergic rhinitis. Classically, these drugs have been considered effective in controlling sneezing, rhinorrhea and itching, though they have not been regarded as particularly effective in application to nasal obstruction. The most recent studies, involving second-generation H1 antihistamines (desloratadine, fexofenadine, levocetirizine, rupatadine), have shown these drugs to offer effects upon nasal obstruction significantly superior to those of placebo. The present review examines the effect of bilastine, a new, potent and highly specific H1 antihistamine without sedative effects or cardiac toxicity, upon nasal obstruction. The analysis of the data from the different clinical trials indicates that in patients with allergic rhinitis, the effect of bilastine upon nasal obstruction is superior to that of placebo and similar to that of other second-generation H1 antihistamines, manifesting within 24 hours after the start of treatment.

    Genome-wide association studies have shown that variants in fat mass and obesity-associated (FTO) gene are robustly associated with body mass index and obesity. These FTO variants are also associated with end stage renal disease and all-cause mortality in chronic kidney diseases. However, the exact role of FTO in kidneys is currently unknown. Here we show that FTO expression is increased after ureteral obstruction and renal fibrosis. Deficiency of the FTO gene attenuates the fibrogenic responses induced by ureteral obstruction in the kidney. Renal tubular cells deficient of FTO produce less α-SMA after TGF-β stimulation. FTO is indispensable for the extracellular matrix synthesis after ureteral obstruction in kidneys. Indeed, global gene transcriptions amplitude is reduced in FTO deficient kidneys after ureteral obstruction. These data establish the importance of FTO in renal fibrosis, which may have potential therapeutic implications.

    Humans live in symbiosis with billions of commensal bacteria. The so-called microbiota live on different biological interfaces such as the skin, the urogenital tract and the gastrointestinal tract. Commensal bacteria replace potentially pathogenic microbes, synthesize vitamins and ferment dietary fibre. An imbalance in the bacterial composition of the intestinal microbiota has been associated with various diseases including gut-associated disorders such as inflammatory bowel diseases, colorectal cancer and nonalcoholic fatty liver disease. Furthermore, a shift in the microbiota composition appears to be of pathophysiological relevance which renders the specific modulation of the intestinal microbiota a promising approach in the treatment of the above mentioned diseases. Our intestinal microbiota composition is mainly modulated by dietary macro- and micronutrients but also by secondary plant compounds and synthetic food additives such as emulsifiers and artificial sweeteners. Nutritional interventions with the purpose to modulate the intestinal microbiota show only limited therapeutic potential in the treatment of gut-associated disorders, which may be due to individual differences in the intestinal microbiota composition and a lack of specificity. A combination of newly established technical analytic approaches involving a machine-learning algorithm may bridge the currently existing limitations by providing a personalized, highly-specific and consequently therapeutically effective microbiota modulation.

    Schizophrenia is associated with significantly increased physical morbidity and mortality particularly secondary to cardiometabolic disorders. In people with schizophrenia, rates of obesity and the metabolic syndrome are high compared to the general population. Whilst the weight gain secondary to antipsychotic medication is largely to blame, other factors include inactivity, poor diet and possibly the illness itself. Obstructive sleep apnoea (OSA) is a common and frequently under-recognized condition which may be associated with disabling symptoms including daytime sleepiness, cognitive impairment, depression, anxiety and long term increases in morbidity and mortality secondary to cardiometabolic disease. As the primary risk factor is obesity, elevated rates of sleep apnoea would therefore seem likely in association with schizophrenia. Thus, OSA might represent a treatable cause of psychiatric and physical co-morbidity in patients with schizophrenia. A review of the literature revealed a paucity of quality research in this area. Available data suggest increased rates of sleep apnoea in schizophrenia and that psychotic symptoms may improve when co-morbid sleep apnoea is treated. Health practitioners may be unaware of the need to screen for sleep apnoea in patients with schizophrenia and the disorder may be significantly under-recognised. Research is required to clarify the epidemiology, consequences and management of sleep apnoea in association with schizophrenia.

    Intestinal neuronal dysplasia type B (IND-B) is a controversial entity among the gastrointestinal neuromuscular disorders. It may occur alone or associated with other neuropathies, such as Hirschsprung’s disease (HD). Chronic constipation is the most common clinical manifestation of patients. IND-B primarily affects young children and mimics HD, but has its own histopathologic features characterized mainly by hyperplasia of the submucosal nerve plexus. Thus, IND-B should be included in the differential diagnoses of organic causes of constipation. In recent years, an increasing number of cases of IND-B in adults have also been described, some presenting severe constipation since childhood and others with the onset of symptoms at adulthood. Despite the intense scientific research in the last decades, there are still knowledge gaps regarding definition, pathogenesis, diagnostic criteria and therapeutic possibilities for IND-B. However, in medical practice, we continue to encounter patients with severe constipation or intestinal obstruction who undergo to diagnostic investigation for HD and their rectal biopsies present hyperganglionosis in the submucosal nerve plexus and other features, consistent with the diagnosis of IND-B. This review critically discusses aspects related to the disease definitions, pathophysiology and genetics, epidemiology distribution, clinical presentation, diagnostic criteria and therapeutic possibilities of this still little-known organic cause of intestinal chronic constipation.

    We aimed to determine the effects of variations in dietary composition on equine gut microbiota and their fermentation products, and proposed that dietary modifications profoundly affect microbial ecosystems and their metabolites. Bacterial communities within the large intestine of three groups of horses were compared using oligonucleotide-RNA hybridisation methodology. Each group consisting of six horses was maintained on (1) a grass-only diet, (2) a concentrate diet (i.e. supplemented with hydrolysable carbohydrates) and (3) a concentrate diet but horses were affected by simple colonic obstruction and distension (SCOD), a prevalent form of dietary-induced intestinal disease. We show that in response to dietary change and intestinal disease, there is a progressive and significant increase in Lachnospiraceae, the Bacteroidetes assemblage and the lactic acid-producing, Bacillus-Lactobacillus-Streptococcus (BLS) group. In contrast, there is a corresponding decrease in the proportion of obligate fibrolytic, acid-intolerant bacteria, Fibrobacter and Ruminococcaceae. Assessment of monocarboxylic acids indicated that there are significantly higher concentrations of lactic acid in the colonic contents of horses maintained on a concentrate diet and those suffering from SCOD, correlating with the observed increase in the population abundance of the BLS group. However, the population size of the Veillonellaceae (lactate utilisers) remained constant in each study group. The inability of this group to respond to increased lactic acid may be a contributory factor to the build-up of lactic acid observed in horses fed a concentrate diet and those suffering from SCOD.

  8. Intestinal absorption of aluminium in renal failure.

    PubMed

    Drüeke, Tilman B

    2002-01-01

    The proportion of the daily ingested aluminium that is absorbed in the intestinal tract has remained a matter of debate for many years because no reliable method of measurement was available. Studies with earlier analytic techniques reported fractional absorption of aluminium from as little as 0.001% to as much as 27% of an oral dose. Measurement of (26)Al by high-energy accelerator mass spectrometry has permitted more accurate analyses. In normal young rats, 0.05-0.1% of ingested aluminium is absorbed in the intestine, of which roughly half goes to the skeleton within 2 h, whereas the remaining half is excreted in the urine, most of it within 48 h. Deposition in organs other than the skeleton appears to be negligible. In healthy human volunteers, the most recent estimates of fractional intestinal (26)Al absorption were also in the range of 0.06-0.1%. In both rats and humans, intestinal absorption of aluminium is subject to many systemic and local factors. The latter include various compounds with which aluminium is complexed in the gut lumen, and gastric acidity. The influence of food is controversial; however, absorption appears higher in the fasted than the post-prandial state. Luminal phosphate concentration decreases aluminium absorption, whereas citrate increases it. For theoretical reasons, silicates should prevent aluminium absorption, but experimental evidence has not supported this theory. Whether water hardness affects aluminium bioavailability remains a matter of debate. General conditions may also modify aluminium absorption and deposition in bone. Examples of these general factors include the uraemic syndrome, diabetes mellitus, secondary hyperparathyroidism, vitamin D status, Alzheimer's disease and Down's syndrome. Awareness of intestinal absorption of aluminium is particularly important, given that aluminium-based binders continue to be used in uraemic patients, despite the hazards of aluminium accumulation.

    Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are crucial events but causes remain poorly defined. A method to clinically 'phenotype' AECOPD have been proposed, and 52 hospitalized chronic obstructive pulmonary disease exacerbations according to underlying aetiology have now been prospectively phenotyped. Multiple exacerbation phenotypes were identified. A subpopulation coinfected with virus and bacteria had a significantly longer length of hospital stay, and this pilot study indicates that exacerbation phenotyping may be advantageous.

    Malignant biliary obstruction is commonly caused by gall bladder carcinoma, cholangiocarcinoma and metastatic nodes. Percutaneous interventions play an important role in managing these patients. Biliary drainage, which forms the major bulk of radiological interventions, can be palliative in inoperable patients or pre-operative to improve liver function prior to surgery. Other interventions include cholecystostomy and radiofrequency ablation. We present here the indications, contraindications, technique and complications of the radiological interventions performed in patients with malignant biliary obstruction. PMID:27247718

    The influence on mucosal healing of luminal nutrient flow and the forces it creates are poorly understood. We hypothesized that altered deformation and extracellular pressure mediate, in part, the effects of defunctionalization on mucosal healing. We created patent or partially obstructing defunctionalizing jejunal Roux-en-Y anastomoses in rats to investigate mucosal healing in the absence or presence of luminal nutrient flow and measured luminal pressures to document partial obstruction. We used serosal acetic acid to induce ulcers in the proximal, distal, and defunctionalized intestinal segments. After 3 days, we assessed ulcer area, proliferation, and phosphorylated ERK. In vitro, we measured proliferation and migration in Caco-2 and IEC-6 intestinal epithelial cells subjected to cyclic strain, increased extracellular pressure, or strain and pressure together. Defunctionalization of intestine without obstruction reduced phosphorylated ERK, slowed ulcer healing, and inhibited mucosal proliferation. This outcome was blocked by PD-98059. Partial obstruction delayed ulcer healing but stimulated proliferation independently of ERK. In vitro, strain increased Caco-2 and IEC-6 proliferation and reduced migration across collagen but reduced proliferation and increased migration across fibronectin. In contrast, increased pressure and the combination of pressure and strain increased proliferation and reduced migration independently of substrate. PD-98059 reduced basal migration but increased migration under pressure. These results suggest that loss of the repetitive distension may decrease mucosal healing in defunctionalized bowel, while increased luminal pressure above anastomoses or in spastic bowel disease could further inhibit mucosal healing, despite peristaltic repetitive strain. ERK may mediate the effects of repetitive deformation but not the effects of pressure. PMID:22997197

  12. [Treatment of obstruction of retinal vessels (author's transl)].

    The treatment of retinal thrombosis is an unresolved problem, mainly because of the numerous factors which participate in their formation; modifications in the walls of veins and arteries, external compressions, changes in the blood count--particularly of the platelets--slowing down of the blood flow, increase in blood viscosity etc. No drug provides constant results. Some widely employed drugs such as vasodilators may be useless or even contra-indicated. Emphasis is placed on anti-coagulants, fibrinolytics, antiaggregating agents and methods of lowering blood viscosity. Their action is difficult to test objectively. Some do appear to be useful, especially in cases of central vein thrombosis. Thrombi of branches of the central vein are apparently inacessible to medical therapy, but occasionally improvement is seen after laser coagulation. This seems to apply also to hemorrhagic glaucoma secondary to retinal obstruction.

  13. Obstructive Sleep Apnea and Atrial Arrhythmogenesis

    2014-01-01

    Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with relevant morbidity and mortality. Besides hypertension, valvular disease and cardiomyopathy, mainly ischemic and dilated, also other conditions like obesity, alcohol abusus, genetic factors and obstructive sleep apnea (OSA) are discussed to contribute to the progression from paroxysmal to persistent AF. The prevalence of OSA among patients with AF is 40-50%. OSA is characterized by periodic or complete cessation of effective breathing during sleep due to obstruction of the upper airways. Obstructive respiratory events result in acute intrathoracic pressure swings and profound changes in blood gases together leading to atrial stretch and acute sympatho-vagal dysbalance resulting in acute apnea related to electrophysiological and hemodynamic alterations. Additionally, repetitive obstructive events in patients with OSA may lead to sympathetic and neurohumoral activation and subsequent structural and functional changes in the atrium creating an arrhythmogenic substrate for AF in the long run. This review focuses on the acute and chronic effects of negative thoracic pressure swings, changes in blood pressure and sympatho-vagal dysbalance induced by obstructive respiratory events on atrial electrophysiology and atrial structure in patients with obstructive sleep apnea.

    In growing subjects, obstruction of the upper airway may lead to excessive vertical facial development. According to the soft-tissue stretching hypothesis (Solow and Kreiborg, 1977) this could be due to an increased cranio-cervical angulation triggered by the airway obstruction. The present study aimed to examine the effect of airway obstruction on cranio-cervical posture in a sample of adult patients with severe obstructive sleep apnoea (OSA). Lateral cephalometric radiographs taken in the natural head position (mirror position) were obtained from 50 male patients aged 28-70 with polysomnographic diagnosis of obstructive sleep apnoea. The Apnoea Index ranged from 21 to 98 episodes per hour with a mean of 54.6. Control samples were available from previous cephalometric studies of head posture in five samples of healthy subjects and one sample of congenitally blind subjects. The average cranio-cervical angle, NSL/OPT, was found to be extremely large (mean 104.1, SD 9.1) exceeding the average values in the control samples by 1-2 standard deviations (P < 0.001). It is suggested that the large cranio-cervical angle in OSA patients is a physiological adaptation aiming to maintain airway adequacy while the head, and thus the visual axis, is kept in its natural relationship to the true vertical. The findings thus provide evidence for the hypothesis that upper airway obstruction may trigger an increase in the cranio-cervical angulation.

  15. Intestinal microbiota and obesity.

    PubMed

    Blaut, Michael; Klaus, Susanne

    The human gut harbors a highly diverse microbial ecosystem of approximately 400 different species, which is characterized by a high interindividual variability. The intestinal microbiota has recently been suggested to contribute to the development of obesity and the metabolic syndrome. Transplantation of gut microbiota from obese mice to nonobese, germ-free mice resulted in transfer of metabolic syndrome-associated features from the donor to the recipient. Proposed mechanisms for the role of gut microbiota include the provision of additional energy by the conversion of dietary fiber to short-chain fatty acids, effects on gut-hormone production, and increased intestinal permeability causing elevated systemic levels of lipopolysaccharides (LPS). This metabolic endotoxemia is suggested to contribute to low-grade inflammation, a characteristic trait of obesity and the metabolic syndrome. Finally, activation of the endocannabinoid system by LPS and/or high-fat diets is discussed as another causal factor. In conclusion, there is ample evidence for a role of gut microbiota in the development of obesity in rodents. However, the magnitude of its contribution to human obesity is still unknown.

    Purpose Obstructive sleep apnea (OSA) is a common clinical disorder characterized by repetitive airway obstruction during sleep. The gold standard for diagnosis of OSA, polysomnogram (PSG), cannot anatomically localize obstruction. Precise identification of obstruction has potential to improve outcomes following surgery. Current diagnostic modalities that provide this information require anesthesia, involve ionizing radiation or disrupt sleep. To mitigate these problems, we conceived that ultrasound (US) technology may be adapted (i) to detect, quantify and localize airway obstruction and (ii) for translational application to home-based testing for OSA. Materials and Methods Segmental airway collapse was induced in 4 fresh cadavers by application of negative pressure. Following visualization of airway obstruction, a rotary US probe was used to acquire transcervical images of the airway before and after induction of obstruction. These images (n=800) were analyzed offline using image processing algorithms. Results Our results show that the non-obstructed airway consistently demonstrated the presence of a US air-tissue interface. Importantly, automated detection of the air-tissue interface strongly correlated with manual measurements. The algorithm correctly detected an air-tissue interface in 90% of the US images while incorrectly detecting it in 20% (area under the curve=0.91). Conclusion The non-invasive detection of airway obstruction using US represents a major step in expanding OSA diagnostics beyond PSG. The preliminary data obtained from our model could spur further research in non-invasive localization of obstruction. US offers the benefit of precise localization of the site of obstruction, with potential for improving outcomes in surgical management PMID:28345075

    OBJECTIVE: Recent work has suggested that within-breath respiratory impedance measurements performed using the forced oscillation technique may help to noninvasively evaluate respiratory mechanics. We investigated the influence of airway obstruction on the within-breath forced oscillation technique in smokers and chronic obstructive pulmonary disease patients and evaluated the contribution of this analysis to the diagnosis of chronic obstructive pulmonary disease. METHODS: Twenty healthy individuals and 20 smokers were assessed. The study also included 74 patients with stable chronic obstructive pulmonary disease. We evaluated the mean respiratory impedance (Zm) as well as values for the inspiration (Zi) and expiration cycles (Ze) at the beginning of inspiration (Zbi) and expiration (Zbe), respectively. The peak-to-peak impedance (Zpp=Zbe-Zbi) and the respiratory cycle dependence (ΔZrs=Ze-Zi) were also analyzed. The diagnostic utility was evaluated by investigating the sensitivity, the specificity and the area under the receiver operating characteristic curve. ClinicalTrials.gov: NCT01888705. RESULTS: Airway obstruction increased the within-breath respiratory impedance parameters that were significantly correlated with the spirometric indices of airway obstruction (R=−0.65, p<0.0001). In contrast to the control subjects and the smokers, the chronic obstructive pulmonary disease patients presented significant expiratory-inspiratory differences (p<0.002). The adverse effects of moderate airway obstruction were detected based on the Zpp with an accuracy of 83%. Additionally, abnormal effects in severe and very severe patients were detected based on the Zm, Zi, Ze, Zbe, Zpp and ΔZrs with a high degree of accuracy (>90%). CONCLUSIONS: We conclude the following: (1) chronic obstructive pulmonary disease introduces higher respiratory cycle dependence, (2) this increase is proportional to airway obstruction, and (3) the within-breath forced oscillation technique may

    Bile acids (BAs) are synthesized in the liver and secreted into the intestine. In the lumen, enteric bacteria metabolize BAs from conjugated, primary forms into more toxic unconjugated, secondary metabolites. Secondary BAs can be injurious to the intestine and may contribute to disease. The epidermal growth factor receptor (EGFR) and the nuclear farnesoid X receptor (FXR) are known to interact with BAs. In this study we examined the effects of BAs on intestinal epithelial cell proliferation and investigated the possible roles for EGFR and FXR in these effects. We report that taurine-conjugated cholic acid (TCA) induced proliferation, while its unconjugated secondary counterpart deoxycholic acid (DCA) inhibited proliferation. TCA stimulated phosphorylation of Src, EGFR, and ERK 1/2. Pharmacological blockade of any of these pathways or genetic ablation of EGFR abrogated TCA-stimulated proliferation. Interestingly, Src or EGFR inhibitors eliminated TCA-induced phosphorylation of both molecules, suggesting that their activation is interdependent. In contrast to TCA, DCA exposure diminished EGFR phosphorylation, and pharmacological or siRNA blockade of FXR abolished DCA-induced inhibition of proliferation. Taken together, these results suggest that TCA induces intestinal cell proliferation via Src, EGFR, and ERK activation. In contrast, DCA inhibits proliferation via an FXR-dependent mechanism that may include downstream inactivation of the EGFR/Src/ERK pathway. Since elevated secondary BA levels are the result of specific bacterial modification, this may provide a mechanism through which an altered microbiota contributes to normal or abnormal intestinal epithelial cell proliferation.

    Primary or secondary nasal tuberculosis is rare and usually, it is considered as an extra pulmonary form of tuberculosis. Nasal tuberculosis infection may spread to maxillary palatal region by contagious or haematogenous route causing palatal perforation. In some instance, it may cause septal perforation with nasal obstruction which may give rise to halitosis. We report a case where, there was bilateral nasal mucosal involvement leading to severe nasal obstruction. This rare manifestation should be considered in areas where the disease is prevalent as delay in diagnosis and treatment could lead to serious and life threatening complications due to local spread from the nose to the para nasal sinuses and brain.

    Winship, Daniel H.; Zboralske, F. Frank

    1967-01-01

    The response of the normal human esophagus to an obstructing intraluminal bolus was investigated and compared to the response evoked by transient intraluminal distention. A balloon, immobilized within the esophagus by external attachment to a force transducer, was inflated with from 3 to 25 ml of air for from 3 to 210 sec. Pressure phenomena occurring in the esophagus were simultaneously recorded from the body of the esophagus above and below the balloon. Transient distention (5 sec or less) with small volumes (5 ml or less) often evoked a secondary peristaltic wave in the esophagus distal to the balloon, but infrequently resulted in the registration of any force exerted upon the balloon to drive it downward. Conversely, distentions of longer duration and with greater volume elicited an esophageal propulsive force exerted upon the balloon oriented to propel it aborally, and much less often evoked a propagated wave of secondary peristalsis. The propulsive force, obviously resulting from esophageal muscular contraction, occurred promptly, and once initiated, was sustained until deflation of the balloon. It varied widely in magnitude, from 4 to 200 g, and was associated with no motor phenomena recorded from the body of the esophagus proximal or distal to the balloon which could account for its presence, onset, magnitude, or duration. The force was inhibited by deglutition, but arrival of the primary peristaltic wave at the bolus resulted in augmentation of the force. When the obstructing balloon was freed from its attachment, the persistent, stationary force was converted to a propagated one that propelled the balloon before it. It the balloon was arrested before entering the stomach, the moving contraction was also arrested and the persistent propulsive force acting upon the balloon was maintained. The velocity of the moving contraction wave was determined in great part by the resistance offered by the bolus. Unrestrained, the balloon was propelled aborally at 4-8 cm

    A few hours after a self-contained underwater breathing apparatus (SCUBA) dive at 30 meters depth, a 49 years-old man complained of diffuse abdominal pain with nausea and vomitus. A laparotomy was performed 36 hours after a conservative treatment because of persistent mechanical small bowel obstruction. The last ileal loop was strangulated between a mobile ceacum and a long sigmoid loop. The man never had previous abdominal surgery. In absence of intestinal necrosis, a caecopexy was done and there was no post-operative complications. The gas distension during the ascension following the Boyle-Mariotte law and its distribution induced in this man with a special anatomy a mechanical small bowel obstruction. The treatment of mobile caecum and the literature of abdominal barotrauma is reviewed.

    Progress in double-balloon endoscopy (DBE) has allowed for the diagnosis and treatment of disease in the postoperative bowel. For example, a short DBE, which has a 2.8 mm working channel and 152 cm working length, is useful for endoscopic retrograde cholangiopancreatography in bowel disease patients. However, afferent loop and Roux-limb obstruction, though rare, is caused by postoperative recurrence of biliary tract cancer with intractable complications. Most of the clinical findings involving these complications are relatively nonspecific and include abdominal pain, nausea, vomiting, fever, and obstructive jaundice. Treatments by surgery, percutaneous transhepatic biliary drainage, percutaneous enteral stent insertion, and endoscopic therapy have been reported. The general conditions of patients with these complications are poor due to cancer progression; therefore, a less invasive treatment is better. We report on the usefulness of metallic stent insertion using an overtube for afferent loop and Roux-limb obstruction caused by postoperative recurrence of biliary tract cancer under short DBE in two patients with complexly reconstructed intestines.

    In most vertebrates, the liver produces bile that is necessary to emulsify absorbed fats and enable the digestion of lipids in the small intestine as well as to excrete bilirubin and other metabolic products. In the liver, the experimental obstruction of the extrahepatic biliary system initiates a complex cascade of pathological events that leads to cholestasis and inflammation resulting in a strong fibrotic reaction originating from the periportal fields. Therefore, surgical ligation of the common bile duct has become the most commonly used model to induce obstructive cholestatic injury in rodents and to study the molecular and cellular events that underlie these pathophysiological mechanisms induced by inappropriate bile flow. In recent years, different surgical techniques have been described that either allow reconnection or reanastomosis after bile duct ligation (BDL), e.g., partial BDL, or other microsurgical methods for specific research questions. However, the most frequently used model is the complete obstruction of the common bile duct that induces a strong fibrotic response after 21 to 28 days. The mortality rate can be high due to infectious complications or technical inaccuracies. Here we provide a detailed surgical procedure for the BDL model in mice that induce a highly reproducible fibrotic response in accordance to the 3R rule for animal welfare postulated by Russel and Burch in 1959.

    BACKGROUND: Gram negative septic events are the commonest source of morbidity and mortality as a result of surgery in jaundiced patients. The large intestine provides the major source of Gram negative bacteria in mammals and is implicated in the pathogenesis of systemic endotoxaemia in obstructive jaundice. Bile salts have an important part in maintaining indigenous microecological homeostasis through their emulsifying properties. AIMS: The aim was to investigate the effects of biliary obstruction and isolated external biliary diversion on gastro-intestinal structure and caecal bacterial flora in relation to bacterial translocation. METHOD: Six groups of adult male Wistar rats were studied (no operation, sham operated, and bile duct ligated (BDL) for one and three weeks and a choledocho-vesical fistula (CDVF) for one week). At the end of the study period plasma was assayed for evidence of endotoxaemia and the animals were tested for bacterial translocation to the mesenteric lymph node complex (MLNC), liver, lungs, and spleen. Quantitative and qualitative bacteriological studies were performed on the caecal contents and segments of colon and terminal ileum were washed and prepared for histological assessment. RESULTS: Bacterial translocation was significantly increased in the BDL1 (68.8%) and BDL3 (60%) groups compared with the sham1 (6.3%), sham3 (9.1%), No operation (0%), and CDVF1 (16.7%) groups. Although translocation was more pronounced in the BDL1 group, this was almost exclusively to the MLNC compared with the more widespread translocation to other organs in the BDL3 group. The BDL3 group was the only group with significantly raised concentrations of endotoxin and anticore glycolipid. The caecal Gram negative aerobic counts were significantly increased in the BDL1 and CDVF1 groups compared with all other groups. There was evidence of structural abnormalities in the terminal ileum of rats jaundiced for three weeks, but not in the other groups. CONCLUSIONS

    Malaria is life threatening and requires urgent diagnosis and treatment. Incidence and mortality are being reduced in endemic areas. Clinical features are unspecific so in imported cases it is vital the history of staying in a malarious area. The first line treatments for Plasmodium falciparum are artemisinin combination therapies, chloroquine in most non-falciparum and intravenous artesunate if any severity criteria. Human infections with intestinal protozoa are distributed worldwide with a high global morbid-mortality. They cause diarrhea and sometimes invasive disease, although most are asymptomatic. In our environment populations at higher risk are children, including adopted abroad, immune-suppressed, travelers, immigrants, people in contact with animals or who engage in oral-anal sex. Diagnostic microscopic examination has low sensitivity improving with antigen detection or molecular methods. Antiparasitic resistances are emerging lately.

    Fat is delivered to tissues by apoB-containing lipoproteins synthesized in the liver and intestine with the help of an intracellular chaperone, microsomal triglyceride transfer protein (MTP). Leptin, a hormone secreted by adipose tissue, acts in the brain and on peripheral tissues to regulate fat storage and metabolism. Our aim was to identify the role of leptin signaling in MTP regulation and lipid absorption using several mouse models deficient in leptin receptor (LEPR) signaling and downstream effectors. Mice with spontaneous LEPR B mutations or targeted ablation of LEPR B in proopiomelanocortin (POMC) or agouti gene related peptide (AGRP) expressing cells had increased triglyceride in plasma, liver, and intestine. Furthermore, melanocortin 4 receptor (MC4R) knockout mice expressed a similar triglyceride phenotype, suggesting that leptin might regulate intestinal MTP expression through the melanocortin pathway. Mechanistic studies revealed that the accumulation of triglyceride in the intestine might be secondary to decreased expression of MTP and lipid absorption in these mice. Surgical and chemical blockade of vagal efferent outflow to the intestine in wild-type mice failed to alter the triglyceride phenotype, demonstrating that central neural control mechanisms were likely not involved in the observed regulation of intestinal MTP. Instead, we found that enterocytes express LEPR, POMC, AGRP, and MC4R. We propose that a peripheral, local gut signaling mechanism involving LEPR B and MC4R regulates intestinal MTP and controls intestinal lipid absorption.

Although information on the synthesis of bile acids by the liver and their transformation to secondary bile acids by the intestinal microbiota was the first example of the importance of the intestinal microbiota in biotransforming chemicals, this review will discuss numerous examples of the mechanisms by which the intestinal microbiota alters the pharmacology and toxicology of drugs and other chemicals. More specifically, the altered pharmacology and toxicology of salicylazosulfapridine, digoxin, l-dopa, acetaminophen, caffeic acid, phosphatidyl choline, carnitine, sorivudine, irinotecan, nonsteroidal anti-inflammatory drugs, heterocyclic amines, melamine, nitrazepam, and lovastatin will be reviewed. In addition, recent data that the intestinal microbiota alters drug metabolism of the host, especially Cyp3a, as well as the significance and potential mechanisms of this phenomenon are summarized. The review will conclude with an update of bile acid research, emphasizing the bile acid receptors (FXR and TGR5) that regulate not only bile acid synthesis and transport but also energy metabolism. Recent data indicate that by altering the intestinal microbiota, either by diet or drugs, one may be able to minimize the adverse effects of the Western diet by altering the composition of bile acids in the intestine that are agonists or antagonists of FXR and TGR5. Therefore, it may be possible to consider the intestinal microbiota as another drug target. PMID:26261286

Recent data indicate that by altering the intestinal microbiota, either by diet or drugs, one may be able to minimize the adverse effects of the Western diet by altering the composition of bile acids in the intestine that are agonists or antagonists of FXR and TGR5. Therefore, it may be possible to consider the intestinal microbiota as another drug target.

  16. Laparoscopic versus open adhesiolysis for small bowel obstruction - a multicenter, prospective, randomized, controlled trial

    Background Laparoscopic adhesiolysis is emerging as an alternative for open surgery in adhesive small bowel obstruction. Retrospective studies suggest that laparoscopic approach shortens hospital stay and reduces complications in these patients. However, no prospective, randomized, controlled trials comparing laparoscopy to open surgery have been published. Methods/Design This is a multicenter, prospective, open label, randomized, controlled trial comparing laparoscopic adhesiolysis to open surgery in patients with computed-tomography diagnosed adhesive small bowel obstruction that is not resolving with conservative management. The primary study endpoint is the length of postoperative hospital stay in days. Sample size was estimated based on preliminary retrospective cohort, which suggested that 102 patients would provide 80% power to detect a difference of 2.5 days in the length of postoperative hospital stay with significance level of 0.05. Secondary endpoints include passage of stool, commencement of enteral nutrition, 30-day mortality, complications, postoperative pain, and the length of sick leave. Tertiary endpoints consist of the rate of ventral hernia and the recurrence of small bowel obstruction during long-term follow-up. Long-term follow-up by letter or telephone interview will take place at 1, 5, and 10 years. Discussion To the best of our knowledge, this trial is the first one aiming to provide level Ib evidence to assess the use of laparoscopy in the treatment of adhesive small bowel obstruction.

    Introduction. A patent urachus is a rare congenital or acquired pathology, which can lead to complications later in life. We describe a case of urachal cystitis as the etiology of small bowel obstruction in an adult without prior intra-abdominal surgery. Case Report. A 64-year-old male presented to the acute care surgery team with a 5-day history of right lower quadrant abdominal pain, distention, nausea, and vomiting. He had a two-month history of urinary retention and his past medical history was significant for benign prostate hyperplasia. On exam, he had evidence of small bowel obstruction. Computed tomography revealed high-grade small bowel obstruction secondary to presumed ruptured appendicitis. In the operating room, an infected urachal cyst was identified with adhesions to the proximal ileum. After lysis of adhesions and resection of the cyst, the patient was subsequently discharged without further issues. Conclusion. Although rare, urachal pathology should be considered in the differential diagnosis when evaluating a patient with small bowel obstruction without prior intraabdominal surgery, hernia, or malignancy.

    Objective To review the efficacy of current treatment options for adults with obstructive sleep apnea (OSA). Methods Review of the literature. Results OSA, characterized by repetitive ≥ 10-second interruptions (apnea) or reductions (hypopnea) in airflow, is initiated by partial or complete collapse in the upper airway despite respiratory effort. When left untreated, OSA is associated with comorbid conditions, such as cardiovascular and metabolic diseases. The current “gold standard” treatment for OSA is continuous positive air pressure (CPAP), which pneumatically stabilizes the upper airways. CPAP has proven efficacy and potential cost savings via decreases in health comorbidities and/or motor-vehicle crashes. However, CPAP treatment is not well-tolerated due to various side effects, and adherence among OSA subjects can be as low as 50% in certain populations. Other treatment options for OSA include improving CPAP tolerability, increasing CPAP adherence through patient interventions, weight loss/exercise, positional therapy, nasal expiratory positive airway pressure, oral pressure therapy, oral appliances, surgery, hypoglossal nerve stimulation, drug treatment, and combining 2 or more of the aforementioned treatments. Despite the many options available to treat OSA, none of them are as efficacious as CPAP. However, many of these treatments are tolerable, and adherence rates are higher than those of the CPAP, making them a more viable treatment option for long-term use. Conclusion Patients need to weigh the benefits and risks of available treatments for OSA. More large randomized controlled studies on treatments or combination of treatments for OSA are needed that measure parameters such as treatment adherence, apnea-hypopnea index, oxygen desaturation, subjective sleepiness, quality of life, and adverse events.

    Purpose of Review A diverse array of microbes colonizes the human intestine. In this review we seek to outline the current state of knowledge on what characterizes a “healthy” or “normal” intestinal microbiome, what factors modify the intestinal microbiome in the healthy state and how the intestinal microbiome affects normal host physiology Recent Findings What constitutes a “normal” or “healthy” intestinal microbiome is an area of active research, but key characteristics may include diversity, richness and a microbial community’s resilience and ability to resist change. A number of factors, including age, the host immune system, host genetics, diet and antibiotic use appear to modify the intestinal microbiome in the normal state. New research shows that the microbiome likely plays a critical role in the healthy human immune system and metabolism. Summary It is clear that there is a complicated bi-directional relationship between the intestinal microbiota and host which is vital to health. An enhanced understanding of this relationship will be critical not only to maximize and maintain human health but also to shape our understanding of disease and to foster new therapeutic approaches.
