    Despite improvements in knowledge of the pathologic physiology of intestinal obstruction, the introduction of gastrointestinal decompression, and more effective antibiotics, obstruction remains a serious disease with a high mortality rate. Although the diagnosis is often obscure, it can usually be made with a fair degree of accuracy by the history alone; pain is fairly constant and characteristically is of a cramping type simulated by very few other lesions. Distention is present in low lesions but absent in high lesions; on the contrary, vomiting is minimal in low lesions but prominent in high lesions. Visible peristaltic waves are almost pathognomonic of intestinal obstruction. Increased peristaltic sounds, as noted by auscultation, are extremely helpful in diagnosis; they are absent in paralytic ileus. Although intestinal obstruction is a surgical lesion, it must be remembered that in the type produced by adhesions the obstruction can be relieved by gastrointestinal decompression in 80 to 90 per cent of cases. Operation is usually indicated a short time after relief because of the probability of recurrence. In practically all other types of obstruction decompression is indicated only while the patient is being prepared for operation. Obviously any type of strangulation demands early operation. Strangulation can usually be diagnosed, particularly if it develops while the patient is under observation. Increase in pain, muscle spasm and pulse rate are important indications of development of strangulation. Dehydration and electrolytic imbalance are produced almost universally in high obstruction. Usually, it is unwise to wait until these two deficiencies are corrected before operation is undertaken, but correction must be well under way at the time of operation. Resections should be avoided in the presence of intestinal obstruction, but obviously will be necessary in strangulation. Operative technique must be expert and carried out with minimal trauma.

    intraoperative evaluation. Intestinal torsion during pregnancy mostly occurs in the sigmoid colon and cecum. Small bowel torsion secondary to adhesions is diagnosed in 42% of pregnant women with intestinal obstruction. The risk of intestinal torsion is higher in the 16-20 and 32-36 weeks of pregnancy and during puerperium. Intestinal torsion results in vessel occlusion which induces more severe symptoms and makes urgent surgical intervention necessary. The overall prognosis is poor--during II and III trimester the fetal mortality rate reaches 36% and 64%, respectively while the risk of maternal death is 6%. Acute intestinal pseudoobstruction can be diagnosed during puerperium, especially following a C-section. Diagnosis is made on the basis of radiological confirmation of colon distension at the cecum as > 9cm, lack of air in the sigmoid colon and rectum, exclusion of mechanical obstruction. In most cases, the treatment is based on easing intestine gas evacuation and administering neostigmine. The authors point out the need for multi-specialty cooperation in the diagnostic-therapeutic process of pregnant women suspected with intestinal obstruction, since any delay in making a correct diagnosis increases the risk of severe complications, both for the woman and the fetus.

    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.

    Chronic intestinal pseudo-obstruction (CIP) is a gastrointestinal motility disorder characterized by chronic symptoms and signs of bowel obstruction in the absence of a fixed, lumen-occluding lesion. Radiographic findings consist of dilated bowel with air-fluid levels. Pseudo-obstruction is an uncommon condition and can result from primary or secondary causes. The management is primarily focused on symptom control and nutritional support to prevent weight loss and malnutrition. The principles of management of patients with CIP involve 1) establishing a correct clinical diagnosis and excluding mechanical obstruction; 2) differentiating between idiopathic and secondary forms; 3) performing a symptomatic and physiologic assessment of the parts of the gastrointestinal (GI) tract involved by manometric and whole gut transit scintigraphic studies; 4) careful assessment of nutritional status of the patient; and 5) developing a therapeutic plan addressing the patient's symptoms and nutritional status. Treatment of CIP includes frequent small meals with a low-fat, low-fiber diet, liquid nutritional supplements may be needed; prokinetic agents such as metoclopramide may help to reduce upper GI symptoms. Trials of drugs such as erythromycin, domperidone, cisapride, and tegaserod may be considered if there is no response. Subcutaneous octreotide may be helpful to improve small bowel dysmotility especially in patients with scleroderma. In patients with symptoms suggestive of bacterial overgrowth, courses of antibiotics such as metronidazole, ciprofloxacin, and doxycycline may be needed. Nutritional assessment and support is an important aspect of management. Enteral nutrition is usually 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. Complications associated with total parenteral nutrition include

    AIM: To investigate the phasic alteration of intestinal homeostasis in an experimental model of intestinal obstruction. METHODS: A rabbit model of intestinal obstruction was established by transforming parts of an infusion set into an in vivo pulled-type locking clamp and creating a uniform controllable loop obstruction in the mesenteric non-avascular zone 8 cm from the distal end of the ileum. The phasic alteration of intestinal homeostasis was studied after intestinal obstruction. The changes in goblet cells, intraepithelial lymphocytes, lamina propria lymphocytes, and intestinal epithelium were quantified from periodic acid-Schiff-stained sections. Ornithine decarboxylase (ODC) activity and serum citrulline levels were measured by high-performance liquid chromatography. Claudin 1 mRNA expression was examined by real-time polymerase chain reaction analysis. Intestinal microorganisms, wet/dry weight ratios, pH values, and endotoxin levels were determined at multiple points after intestinal obstruction. Furthermore, the number and ratio of CD3+, CD4+ and CD8+ T cells were determined by flow cytometry, and secretory IgA levels were measured with an enzyme-linked immunosorbent assay. RESULTS: A suitable controllable rabbit model of intestinal obstruction was established. Intestinal obstruction induced goblet cell damage and reduced cell number. Further indicators of epithelial cell damage were observed as reduced serum citrulline levels and claudin 1 gene expression, and a transient increase in ODC activity. In addition, the wet/dry weight ratio and pH of the intestinal lumen were also dramatically altered. The ratio of Bacillus bifidus and enterobacteria was reversed following intestinal obstruction. The number and area of Peyer’s patches first increased then sharply decreased after the intestinal obstruction, along with an alteration in the ratio of CD4/CD8+ T cells, driven by an increase in CD3+ and CD8+ T cells and a decrease in CD4+ T cells.

    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.

    A retrospective analysis of 70 consecutive patients with a clinical diagnosis of intestinal obstruction from January 1983 to September 1985 was reviewed. Mean age was 62 years. Etiological factors included adhesions 50 percent, malignancy 24 percent, volvulus 12 percent, diverticulitis 7 percent, hernias 4 percent, and radiation enteritis, mesenteric infarction, and perforation of the cecum in the remaining 3 percent. Complications included wound infection 9 percent (n = 6), intra-abdominal sepsis 7 percent (n = 5), and recurrent small bowel obstruction 4 percent (n = 3). Overall mortality was 24 percent (n = 7). Results of the univariant analysis showed no association between the clinical signs of intestinal obstruction, that is, fever, tachycardia, leukocytosis, and local tenderness, and gangrenous bowel. A multiple regression analysis showed, however, that only 14 percent of the variance was able to predict the gangrenous bowel based on clinical signs. In conclusion, the classical signs of intestinal obstruction are poor indicators for compromised bowel, and early surgical intervention will reduce the incidence of ischemic bowel and mortality.

    Background/Aims—Chronic intestinal pseudo-obstruction (CIPO) reflects a dysfunction of the visceral smooth muscle or the enteric nervous system. Gastrointestinal manifestations are common in systemic lupus erythematosus (SLE) but CIPO has not been reported. Features of CIPO are reported in five patients with SLE. 
Methods—From 1988 to 1993, five patients with SLE or SLE-like syndrome were hospitalised for gastrointestinal manometric studies. CIPO was the onset feature in two cases. Antroduodenal manometry (three hours fasting, two hours fed) was performed in all patients, and oesophageal manometry in four. 
Results—Intestinal hypomotility associated with reduced bladder capacity and bilateral ureteral distension was found in four patients and aperistalsis of the oesophagus in three. Treatment, which consisted of high dose corticosteroids, parenteral nutrition, promotility agents, and antibiotics, led to remission of both CIPO and urinary abnormalities in all cases. Antroduodenal manometry performed in two patients after remission showed increased intestinal motility. One patient died, and postmortem examination showed intestinal vasculitis. 
Conclusions—CIPO in SLE is a life threatening situation that can be reversed by treatment. It may be: (a) a complication or onset feature of the disease; (b) secondary to smooth muscle involvement; (c) associated with ureteral and vesical involvement; (d) the result of intestinal vasculitis.

    Small intestinal anisakiasis is a rare disease that is very difficult to diagnose, and its initial diagnosis is often surgical. However, it is typically a benign disease that resolves with conservative treatment, and unnecessary surgery can be avoided if it is appropriately diagnosed. This case report is an example of small intestinal obstruction caused by anisakiasis that resolved with conservative treatment. A 63-year-old man admitted to our department with acute abdominal pain. A history of raw fish (sushi) ingestion was recorded. Abdominal CT demonstrated small intestinal dilatation with wall thickening and contrast enhancement. Ascitic fluid was found on the liver surface and in the Douglas pouch. His IgE (RIST) was elevated, and he tested positive for the anti-Anisakis antibodies IgG and IgA. Small intestinal obstruction by anisakiasis was highly suspected and conservative treatment was performed, ileus tube, fasting, and fluid replacement. Symptoms quickly resolved, and he was discharged on the seventh day of admission. Small intestinal anisakiasis is a relatively uncommon disease, the diagnosis of which may be difficult. Because it is a self-limiting disease that usually resolves in 1-2 weeks, a conservative approach is advisable to avoid unnecessary surgery. PMID:24455340

    Intestinal obstruction is a frequently encountered entity in surgical practice. The signs & symptoms, many a times, are suggestive of the level of obstruction, making the diagnosis of obstruction evident. There are various causes of intestinal obstruction which diversify to an enormous extent, stamping on the famous paradigm for the mysterious nature of the abdomen being referred to as the Pandora's Box. In accordance with the above saying, we report a rare case of a desmoid tumour, presenting as intestinal obstruction, which entices us to strongly believe the same. PMID:26889339

    OBJECTIVES: The goal of this study was to assess the relationship between intestinal obstruction and the prognosis of colorectal carcinoma. METHODS: Data pertaining to 4,501 colorectal carcinoma patients were extracted from the national colorectal registry and analysed. Survival analysis was performed using the Kaplan-Meier method. The log-rank test was used to compare the survival rate between patients with intestinal obstruction and those without intestinal obstruction. The p-values<0.05 were considered to indicate statistical significance. Simple Cox proportional hazards regression analysis was used to estimate the crude hazard ratio of mortality from colorectal cancer. RESULTS: Intestinal obstruction was reported in more than 13% of patients. The 3-year survival rate after treatment was 48.3% (95% confidence interval [CI], 43.9 to 52.8) for patients with intestinal obstruction (n=593) and 54.9% (95% CI, 53.1 to 56.6) for patients without intestinal obstruction (n=3,908). The 5-year survival rate for patients with intestinal obstruction was 37.3% (95% CI, 31.9 to 42.8), which was lower than that of patients without intestinal obstruction (45.6%; 95% CI, 43.5 to 47.7). After adjusting the hazard ratio for other prognostic variables, intestinal obstruction had a statistically significant negative correlation with the survival rate of colorectal cancer patients, with an adjusted hazard ratio of 1.22 (p=0.008). CONCLUSIONS: The presence of intestinal obstruction is associated with a lower survival rate among colorectal cancer patients. PMID:25868638

    Large bowel obstruction (LBO) is most commonly due to malignancy, volvulus, hernia, diverticular disease and inflammatory bowel disease. LBO due to adhesions is unusual. A literature review was conducted which revealed that only a few such cases have been reported. We report two cases of LBO secondary to adhesions in patients, one with and one without a past abdominal surgical history. We highlight that while rare, the aetiology of LBO secondary to adhesions must be considered in the differential diagnosis in patients presenting with obstructive symptoms. PMID:25650387

    2015-01-01

    Patients with incurable, advanced abdominal or pelvic malignancy often present to acute surgical departments with symptoms and signs of intestinal obstruction. It is rare for bowel strangulation to occur in these presentations, and spontaneous resolution often occurs, so the luxury of time should be afforded while decisions are made regarding surgery. Cross-sectional imaging is valuable in determining the underlying mechanism and pathology. The majority of these patients will not be suitable for an operation, and will be best managed in conjunction with a palliative medicine team. Surgeons require a good working knowledge of the mechanisms of action of anti-emetics, anti-secretories and analgesics to tailor early management to individual patients, while decisions regarding potential surgery are made. Deciding if and when to perform operative intervention in this group is complex, and fraught with both technical and emotional challenges. Surgery in this group is highly morbid, with no current evidence available concerning quality of life following surgery. The limited evidence concerning operative strategy suggests that resection and primary anastomosis results in improved survival, over bypass or stoma formation. Realistic prognostication and involvement of the patient, care-givers and the multidisciplinary team in treatment decisions is mandatory if optimum outcomes are to be achieved. PMID:26288731

    Introduction. Gossypiboma (GP) is a term used to express the mass resulting from forgotten cotton sponge in operations. Rarely, a transmural migration may occur into the gastrointestinal lumen without creating any defect by GP. Laparotomy or endoscopic removal may be required, by the way it can be taken out of the body itself by intestinal ways. In this study, we reported a case of mechanical intestinal obstruction causing GP. Case. The fifty-one-year-old female patient admitted to the emergency department with the complaints of mechanical intestinal obstruction and had a history of open cholecystectomy 20 years ago. There were the findings of intestinal obstruction in abdominal plain radiography and computerized tomography. The sponge that obstructed the lumen completely 40 cm proximal to the ileocecal valve was identified in the laparotomy with the diagnosis of brid ileus. The small intestine was closed over double-fold after removal of sponge. Transmural migration of abdominal-remained sponge was thought to be occurred without creating a defect after cholecystectomy. Postoperatively, the patient was discharged without having any problems at 4th day of hospitalization. Conclusion. Although it is a rare situation in routine clinical practice, GP should be considered as a differential diagnosis in the patients who had a diagnosis of mechanical intestinal obstruction, and laparotomy was applied before. As GP may lead to situations which cause mortality, all precautions should be taken to prevent it. PMID:23133784

    The prokinetic effects of erythromycin, a macrolide antibiotic, on the gastrointestinal tract as a motilin receptor agonist and its potential value for the treatment of gastrointestinal motility disorders have recently attracted interest. The effects of erythromycin on the clinical symptoms and gastrointestinal motility of patients with chronic idiopathic pseudo-obstruction have not been investigated extensively. We presented a case of chronic idiopathic intestinal pseudo-obstruction, in a 67-year-old man in whom oral erythromycin (900 mg/day) dramatically improved postprandial abdominal distention, nausea, and vomiting. Other agents with prokinetic effects on intestinal motility, i.e., cisapride, domperidone, metoclopramide, and trimebutine maleate did not have a favorable effect. Gastric emptying, measured by the sulfamethizole method; and intestinal transit, evaluated using radio-opaque markers, were markedly improved by treatment with erythromycin. Our experience suggests that the prokinetic effects of erythromycin may be of therapeutic value in chronic idiopathic intestinal pseudo-obstruction. PMID:9027652

    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

    Intestinal obstruction is a common clinical entity encountered in surgical practice. The objective of this report is to corroborate an atypical scenario of intestinal obstruction in a Chinese patient and to focus on the diagnosis and treatment. A 27-year-old male presented with a history of gastric pain combined with nausea and abdominal distension that had been present for 5 d. The presence of a foreign body was detected by computed tomography and observed as an abnormal density within the stomach. A diospyrobezoar was revealed during gastroscopy, the extraction of which was prevented due to its size and firmness. An endoscopic holmium laser joined with a snare was used to fragment the obstruction, which was followed by management with a conservative "sandwich" treatment strategy involving intestinal decompression with an ileus tube and Coca-Cola lavage between endoscopic lithotripsy fragmentation procedures. This strategy resulted in the successful removal of the diospyrobezoar along with multiple small bowel obstructions. The patient was discharged after abatement of symptoms. The case presented here demonstrates the implementation of a conservative, yet successful, treatment as an alternative to conventional surgical removal of intestinal obstructions. PMID:25561823

    Meckel's diverticulum occurs in about 1-3% of general population. The majority of them are asymptomatic and incidentally found at laparotomy. The most common complication due to Meckel's diverticulum in adults is intestinal obstruction. The frequency of symptoms decreases with age. Enteroliths are rarely formed in a Meckel's diverticulum and are known to cause intestinal obstruction. These should be considered in the differential diagnosis of radioopaque shadows in the plain abdominal films. We describe a rare presentation of Meckel's diverticulum in an elderly woman.

    Mechanical obstructions are mainly linked to old age which can favour constipation and faecal impaction, to abdominal surgery, to chronic inflammatory diseases of the intestine or to digestive tract malignant tumours. In addition to monitoring the patient and ensuring their compliance with prescribed treatments, educating the patient with the aim of restoring a good nutritional status is essential. PMID:26743368

    Owing to their rare occurrence, persimmon bezoars are often overlooked as a cause of small bowel obstruction. We herein report a small bowel obstruction in a 67-year-old Japanese female who regularly consumed persimmons in autumn. The patient presented to our hospital with typical complaints of abdominal distension with pain for 2 days. Based on the patient's history of a cesarean section 34 years ago, we initially diagnosed her with small bowel obstruction resulting from adhesions and placed an ileus tube. At first, the patient rejected the operation in spite of our recommendation. After 10 days, because the ileus tube was unable to relieve the obstruction, finally surgery was scheduled. Upon releasing the obstruction by partial resection of the small bowel, we found an impacted bezoar without any evidence of adhesions. After stone analysis, we first realized her regular persimmon intake. This case serves as an important reminder to obtain dietary history in order to investigate all possible causes of small bowel obstruction when intestinal obstruction is suspected. PMID:26595493

    Intestinal pseudo-obstruction secondary to systemic lupus erythematosus (SLE) is a rare syndrome described in recent decades. There are slightly over 30 published cases in the English language literature, primarily associated with renal and hematological disease activity. Its presentation and evolution are a diagnostic challenge for the clinician. We present four cases of intestinal pseudo-obstruction due to lupus in young Mexican females. One patient had a previous diagnosis of SLE and all presented with a urinary tract infection of varying degrees of severity during their evolution. We consider that recognition of the disease is of vital importance because it allows for establishing appropriate management, leading to a better prognosis and avoiding unnecessary surgery and complications.

    The combination of uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis represents a rare congenital anomaly called Herlyn-Werner-Wunderlich syndrome (HWWS) or obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome. Several anomalies have recently been reported to be associated with this syndrome. The present patient with HHWS had multiple anomalies: intestinal non-rotation, anomalies of the large vessels of the abdomen including duplication of the inferior vena cava and a high-riding aortic bifurcation, and hypodontia. Hypodontia has never been reported in a patient with HWWS. The patient underwent a preventative Ladd's procedure and vaginal reconstruction. To prevent serious complications from concomitant anomalies such as intestinal malrotation, a patient with HWWS should be evaluated in detail for associated malformations. PMID:23910815

    A case is reported in which a woman was diagnosed with ureteral obstruction secondary to endometriosis after cystourethrogram, retrograde pyelogram and a renal scan. After unsuccessful treatment with danazol, a retroperitoneal ureteroneocystotomy was performed. The ureter was found to be obstructed by dense fibrous tissue that contained endometrial glands. It was concluded that danazol is unlikely to relieve endometriotic ureteric obstruction once dense fibrosis has occurred. 8 references, 2 figures.

    Phaeochromocytomas are rare neuroendocrine tumours with variable clinical signs and symptoms. Hypertension, tachycardia, sweating and headaches are cardinal manifestations. Although nausea and abdominal pain are the more common gastrointestinal features, rare gastrointestinal spectrums have been reported that can mimic abdominal emergencies. Metabolic effects of hypercatecholaminaemia are vast and one such rare presentation is lactic acidosis. We describe a case of phaeochromocytoma presenting with both intestinal pseudo-obstruction as well as lactic acidosis. This case report highlights the importance of having a high index of suspicion for and early recognition of the gastrointestinal and metabolic manifestations of phaeochromocytomas. PMID:26311913

    Vomiting, often caused by mechanical intestinal obstruction, is common in dogs. Equivocal radiographic signs often necessitate repeat radiographs or additional imaging procedures. For our prospective, case-controlled, accuracy study, we hypothesized the following: (1) using computed tomography (CT), radiologists will be more sensitive and specific for detecting mechanical intestinal obstruction and recommending surgery compared to using radiographs; and (2) using measurements, radiologists will be more sensitive and specific using radiographs or CT for detecting mechanical intestinal obstruction and recommending surgery. Twenty dogs had abdominal radiographs and abdominal CT. Seventeen dogs had abdominal surgery and three dogs were not obstructed based on clinical follow-up. Confidence levels (five-point scale) of three experienced radiologists for mechanical intestinal obstruction and recommending surgery were recorded before and after making selected measurements. Eight dogs had surgically confirmed mechanical intestinal obstruction, and 12 dogs did not have obstruction. For detecting mechanical intestinal obstruction, CT was more sensitive (95.8% vs. 79.2%) and specific (80.6% vs. 69.4%) compared to radiographs, but the difference was not statistically significant. For recommending surgery, radiography was more sensitive (91.7% vs. 83.3%) and specific (83.3% vs. 72.2%) than using CT, but differences were not statistically significant. We reported objective CT measurements for predicting small mechanical intestinal obstruction. By incorporating these objective data, the diagnosis of mechanical intestinal obstruction changed in five of 120 instances (radiographs and CT). In no instance (0/120), did the objective data change the recommendation for surgery. Using CT or abdominal radiographs for the detection of canine mechanical intestinal obstruction is sensitive and specific when evaluated by experienced veterinary radiologists. PMID:27038072

    Background/Aim: The etiology of acute intestinal obstruction, which is one of the commonest surgical emergencies, varies between countries and has also changed over the decades. We aimed to provide a complete epidemiological description of acute intestinal obstruction in a tertiary care hospital in Eastern India. Materials and Methods: This was a retrospective study of patients admitted in our unit with a diagnosis of acute intestinal obstruction between the years 2005 and 2008 at Medical College, Calcutta. The study comprised of 367 patients. Results: Acute intestinal obstruction was the diagnosis in 9.87% of all patients admitted with males (75.20%) grossly outnumbering females. The commonest age group affected was 20-60 years. In our patients, the main cause of obstruction was obstructed hernia followed by malignancy with adhesions coming third. Intestinal tuberculosis was an important cause for obstruction in our patients comprising 14.17% of patients. Conservative management was advocated in 79 patients while the rest underwent surgery. Postoperative complications occurred in 95 patients and of these, 38 patients had a single complication and the rest, more than 1. The main complications were wound infection, basal atelectasis, burst abdomen and prolonged ileus. The mortality rate was 7.35% (27 patients). The highest mortality occurred in those with intestinal tuberculosis. Conclusion: This study demonstrates that the pattern of intestinal obstruction differs from the Western world with obstructed hernias being the most important cause and also emphasizes the fact that intestinal tuberculosis assumes a prominent role. It also highlights the necessity of using universal precautions because of the ever increasing number of HIV patients in those with intestinal obstruction. PMID:20871195

    Wild banana (Musa acuminata subsp. microcarpa) seed phytobezoar rectal impaction in adult is a rare entity. Here, we report a 75-year-old male with dementia who presented with lower abdominal pain, per-rectal bleeding and overflow faecal incontinence. Our investigation discovered a large wild banana seed phytobezoar impacted in the rectum causing intestinal obstruction, stercoral ulcer and faecal overflow incontinence. In this article, we discuss the patient's clinical findings, imaging and management. The culprit plant was identified and depicted. This may be the first report of its kind. Public consumption of these wild bananas should be curtailed. It is hoped that this report would increase the awareness of such condition and its identification. PMID:27574355

    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.

    Introduction Neonatal intestinal obstruction is the most common surgical emergency in a newborn requiring prompt intervention. There are only very few studies done in world regarding pattern of neonatal intestinal obstruction. Aim This study was conducted to see the aetiological spectrum of neonatal intestinal obstruction and to find out the problems and outcome of surgical management. Materials and Methods This study was done retrospectively to include all operated cases of neonatal intestinal obstruction from June 2000 to May 2015 and various factors affecting outcome were analysed. Results A total of 298 newborns were included in the study. Male-female ratio was 1.8:1. Gestational age was variable from 32 to 42 weeks (mean = 37.5 weeks) and birth weight from 1.4 to 3.5kg (mean= 2.25 kg). Mean age of presentation was 6 days with intestinal atresia (49.6%) as the commonest cause. Other causes were Hirschsprung (13%), Malrotation gut (11.7%), Meconium ileus (7.3%), patent VID (5%), duodenal obstruction (4%), duplication cyst (3.7%), obstructed hernia (2.7%) and others (2.7%). Mortality rate was 16.4% with sepsis both pre as well as post operative as the main cause of mortality. Conclusion The morbidity and mortality of neonatal intestinal obstruction has improved over last few years mainly due to antenatal detection, early intervention, meticulous resuscitation before surgery along with good NICU care.

    Adenolipoma of the thyroid gland is a rare benign neoplasm composed of normal thyroid and mature adipose tissue. Ordinarily, only a small amount of fat exists in a normal thyroid gland. CT and MRI may differentiate between benign and malignant lesions, and fine-needle aspirate often assists diagnosis. Surgical excision for adenolipoma is considered curative. We report the case of a 67-year-old man presenting with a large neck lump and evidence of airway obstruction. Imaging revealed a 97×70 mm left thyroid mass with retropharyngeal extension and laryngotracheal compression. Hemithyroidectomy was performed with subsequent histology confirming a large thyroid adenolipoma. The patient's symptoms resolved and he remains asymptomatic with no sign of recurrence 2 years postsurgery. PMID:25199190

    AIM: To determine the value of bowel sounds analysis using an electronic stethoscope to support a clinical diagnosis of intestinal obstruction. METHODS: Subjects were patients who presented with a diagnosis of possible intestinal obstruction based on symptoms, signs, and radiological findings. A 3M™ Littmann® Model 4100 electronic stethoscope was used in this study. With the patients lying supine, six 8-second recordings of bowel sounds were taken from each patient from the lower abdomen. The recordings were analysed for sound duration, sound-to-sound interval, dominant frequency, and peak frequency. Clinical and radiological data were reviewed and the patients were classified as having either acute, subacute, or no bowel obstruction. Comparison of bowel sound characteristics was made between these subgroups of patients. In the presence of an obstruction, the site of obstruction was identified and bowel calibre was also measured to correlate with bowel sounds. RESULTS: A total of 71 patients were studied during the period July 2009 to January 2011. Forty patients had acute bowel obstruction (27 small bowel obstruction and 13 large bowel obstruction), 11 had subacute bowel obstruction (eight in the small bowel and three in large bowel) and 20 had no bowel obstruction (diagnoses of other conditions were made). Twenty-five patients received surgical intervention (35.2%) during the same admission for acute abdominal conditions. A total of 426 recordings were made and 420 recordings were used for analysis. There was no significant difference in sound-to-sound interval, dominant frequency, and peak frequency among patients with acute bowel obstruction, subacute bowel obstruction, and no bowel obstruction. In acute large bowel obstruction, the sound duration was significantly longer (median 0.81 s vs 0.55 s, P = 0.021) and the dominant frequency was significantly higher (median 440 Hz vs 288 Hz, P = 0.003) when compared to acute small bowel obstruction.

    Enteropathy associated T-cell lymphoma (EATL) is a rare complication of celiac disease (CD). We report a case of EATL associated with CD revealed by acute intestinal obstruction. A North African woman of 38 years old with a history of infertility and chronic abdominal pain was admitted in emergency with acute intestinal obstruction. During the surgery, we found a tumor on the small intestine with mesenteric lymphadenopathy. Histology and immunohistochemistry of the specimen objectified a digestive T lymphoma CD3+ and immunological assessment of celiac disease was positive. The diagnosis of EATL was thus retained. Chemotherapy (CHOEP protocol) was established as well as gluten-free diet with a complete response to treatment. The EATL is a rare complication of CD that can be revealed by intestinal obstruction. The prognosis can be improved by early treatment involving surgery and chemotherapy. Its prevention requires early diagnosis of celiac and gluten-free diets. PMID:27217874

    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 Drosophila C virus (DCV) is a positive-sense RNA virus belonging to the Dicistroviridae family. This natural pathogen of the model organism Drosophila melanogaster is commonly used to investigate antiviral host defense in flies, which involves both RNA interference and inducible responses. Although lethality is used routinely as a readout for the efficiency of the antiviral immune response in these studies, virus-induced pathologies in flies still are poorly understood. Here, we characterize the pathogenesis associated with systemic DCV infection. Comparison of the transcriptome of flies infected with DCV or two other positive-sense RNA viruses, Flock House virus and Sindbis virus, reveals that DCV infection, unlike those of the other two viruses, represses the expression of a large number of genes. Several of these genes are expressed specifically in the midgut and also are repressed by starvation. We show that systemic DCV infection triggers a nutritional stress in Drosophila which results from intestinal obstruction with the accumulation of peritrophic matrix at the entry of the midgut and the accumulation of the food ingested in the crop, a blind muscular food storage organ. The related virus cricket paralysis virus (CrPV), which efficiently grows in Drosophila, does not trigger this pathology. We show that DCV, but not CrPV, infects the smooth muscles surrounding the crop, causing extensive cytopathology and strongly reducing the rate of contractions. We conclude that the pathogenesis associated with systemic DCV infection results from the tropism of the virus for an important organ within the foregut of dipteran insects, the crop. IMPORTANCE DCV is one of the few identified natural viral pathogens affecting the model organism Drosophila melanogaster. As such, it is an important virus for the deciphering of host-virus interactions in insects. We characterize here the pathogenesis associated with DCV infection in flies and show that it results from the

    Approximately 3 billion people around the world cook and heat their homes using solid fuels in open fires and rudimentary stoves, resulting in household air pollution. Household air pollution secondary to indoor combustion of solid fuel is associated with multiple chronic obstructive pulmonary disease (COPD) outcomes. The exposure is associated with both chronic bronchitis and emphysema phenotypes of COPD as well as a distinct form of obstructive airway disease called bronchial anthracofibrosis. COPD from household air pollution differs from COPD from tobacco smoke with respect to its disproportionately greater bronchial involvement, lesser emphysematous change, greater impact on quality of life, and possibly greater oxygen desaturation and pulmonary hypertensive changes. Interventions that decrease exposure to biomass smoke may decrease the risk for incident COPD and attenuate the longitudinal decline in lung function, but more data on exposure-response relationships from well-designed longitudinal studies are needed.

    Intestinal obstruction in neonatal period is an emergency caused by many surgical causes. An extremely rare surgical cause in this group of age is intussusception which can be easily confused with other surgical entities. In several reports, a significant number of the infants who were included in the study population were believed to have necrotizing enterocolitis (NEC). We present a rare cause of small intestine obstruction in a preterm female infant that can be easily misdiagnosed and confused preoperatively with other clinical entities particular for this period.

    A rare case of complete large bowel obstruction in a pregnant woman, without previous surgical history, due to previously undiagnosed reversed intestinal rotation is presented. The young woman was admitted with progressive nausea and vomiting which did not respond to conventional therapy. Her plain abdominal film revealed signs of small bowel obstruction. On laparotomy, her transverse colon was found to be located beneath the root of small bowel mesentery and completely obstructed by congenital fibrous bands. Postoperative recovery was unremarkable. Surgery for this unusual developmental anomaly is discussed. PMID:26075133

    Phytobezoars are a well-known, though rare, cause of mechanical alimentary tract obstruction. They occur mainly in patients who have undergone abdominal surgery, where most literature reports describe the causes as persimmons and oranges. We report four cases, seen within a period of 19 months in Laos, with intestinal obstruction caused by phytobezoars from jungle banana seeds. They had no history of previous gastrointestinal surgery. The recommended therapy in total obstruction is laparotomy, "milking" through the ileocaecal junction, or enterotomy and direct extraction. As recurrence and presentation at multiple sites are possible, all of the gastrointestinal tract should be thoroughly examined intraoperatively. PMID:15564195

    Adult intestinal hamartomas is uncommon, intussusception caused by simple intestinal hamartomas are extremely rare. However, there is no report yet like our isolated giant ileum hamartoma. We report an unusual case of a 34-year-old woman who suffered abdominal pain for more than 1 year, and accompanied with obvious symptoms of anemia. The admission CT examination revealed small bowel intussusception. So we had a laparotomy for her. After the reduction of the intussusception, we found a huge mass of 7.5 cm × 2 cm × 2 cm in the intestine, and postoperative pathology showed ileum hamartoma. PMID:27162788

    Two birds from a zoological collection suffered fatal intestinal obstruction after each ingested single particles of polyacrylamide gel. Polyacrylamide gel, used in soils for gardening and agriculture, exists as small granules in the dehydrated state but expands markedly upon exposure to water. Polyacrylamide gel might, therefore, be an unrecognized hazard for captive and wild birds and other small animals if consumed. PMID:20235459

    Background and Objective: Cases presenting with intestinal perforation and obstruction constitute a substantial work load on our surgical service. Etiologies vary in underdeveloped and developed countries. Histopathological examination of resected intestine is expected to provide the definite evidence of the underlying etiology- guiding a better health care planning for preventive measures. Our objective was to study the spectrum of histopathological findings in resected intestines from cases of intestinal obstruction and perforation in our local population to document the underlying etiology. Methods: A total of 120 cases of intestinal resection were included. Detailed gross and microscopic examination with routine stains was performed. Definite evidence of any specific etiology on the basis of morphology was documented. Results: A total of 95 cases with clinical/radiological diagnosis of obstruction (79.2%) and 25 of intestinal, perforation (20.8%) were included. Tuberculous enteritis was the commonest etiology (n=41; 43.1%) in cases of intestinal obstruction followed by malignant tumours (n=30; 31.5%). ischemic infarct/gangrene, post op illeal adhesions, polyps and ulcerative colitis followed. In cases of perforation, Typhoid enteritis (n=15; 60%), was the commonest pathology followed by idiopathic perforation (n=5; 20%), tuberculous enteritis (n=3;12%), carcinoma (4%) and ulcerative coliti (4%). Conclusion : In developing countries infective etiology remains a dominant cause of intestinal obstruction and perforation. Its presentation in younger age leading to intestinal resection demands effective preventive measures in this part of the world to prevent morbidity and mortality. PMID:24772146

    Signs of mild colic, intermittent lethargy, and weight loss of 6 weeks' duration in a 2-year-old Quarter Horse gelding were attributed to persimmon (Diospyros virginiana) phytobezoar formation. Diagnosis of the phytobezoar was facilitated by gastric endoscopy. Signs of gastrointestinal tract obstruction were associated with a large phytobezoar in the lumen of the stomach, gastric ulceration, and obstruction of the small intestine (as a consequence of fragmentation of the primary bezoar). Conservative treatment, using mineral oil and dioctyl sodium sulfosuccinate, was unsuccessful. A celiotomy was performed, and gastric impaction and partial obstruction of the small intestine associated with phytobezoar formation and fragmentation were identified. The horse made a complete recovery following removal of all phytobezoars. Persimmon phytobezoar should be considered in the fall and winter as a possible cause of lethargy, colic, and weight loss in horses allowed access to persimmon fruit. PMID:10767970

    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

    Intestinal obstruction in a 2-year-old girl with a histologically proven diagnosis of retroperitoneal yolk sac carcinoma developed after the second course of anticancer chemotherapy. Nonoperative treatment was not effective. Because the patient had fallen into a state of chemotherapy-induced myelosuppression, surgery was ruled out. Thus, hyperbaric oxygen therapy was the next treatment of choice. It was performed twice under hyperbaric oxygen conditions at 2.8 atmospheric pressure for 111 minutes. After the procedure, her general status recovered well. The air-fluid level disappeared on the radiograph, and no adverse effects were observed. Later, a surgical removal of the primary tumor was performed successfully, but an intestinal resection was not required. This is the first instance in which we performed hyperbaric oxygen therapy on a child in the management of an intestinal obstruction. Based on the successful outcome in this case, hyperbaric oxygen therapy is suggested to be a useful adjunct to nonoperative therapy for intestinal obstruction when a patient's overall state does not allow operative intervention.

    Background—Chronic idiopathic intestinal pseudo-obstruction, a syndrome of ineffectual motility due to a primary disorder of enteric nerve or muscle, is rare. 
Aims—To determine the clinical spectrum, underlying pathologies, response to treatments, and prognosis in a consecutive unselected group of patients. 
Methods—Cross sectional study of all patients with clinical and radiological features of intestinal obstruction in the absence of organic obstruction, associated with dilated small intestine (with or without dilated large intestine), being actively managed in one tertiary referral centre at one time. 
Results—Twenty patients (11 men and nine women, median age 43 years, range 22-67) fulfilled the diganostic criteria. Median age at onset of symptoms was 17 years (range two weeks to 59 years). Two patients had an autosomally dominant inherited visceral myopathy. Major presenting symptoms were pain (80%), vomiting (75%), constipation (40%), and diarrhoea (20%). Eighteen patients required abdominal surgery, and a further patient had a full thickness rectal biopsy. The mean time interval from symptom onset to first operation was 5.8 years. Histology showed visceral myopathy in 13, visceral neuropathy in three, and was indeterminate in three. In the one other patient small bowel motility studies were suggestive of neuropathy. Two patients died within two years of symptom onset, one from generalised thrombosis and the other from an inflammatory myopathy. Of the remaining 18 patients, eight were nutritionally independent of supplements, two had gastrostomy or jejunostomy feeds, and eight were receiving home parenteral nutrition. Five patients were opiate dependent, only one patient had benefited from prokinetic drug therapy, and five patients required formal psychological intervention and support. 
Conclusions—In a referral setting visceral myopathy is the most common diagnosis in this heterogeneous syndrome, the course of the illness is usually

    The patients on anticoagulation therapy especially warfarin can develop gastrointestinal bleed, gum bleeding, hematuria or ecchymosis. Rarely do such patients present with hemoperitoneum producing symptoms. Hemoperitoneum can produce shock, cause compression symptoms or may even be fatal. Such patients can be managed conservatively or may need surgical exploration for ongoing bleeding or decompression. We had a patient taking warfarin who presented with hemoperitoneum producing intestinal symptoms. The patient was managed conservatively with fluid and blood product replacement and stopping warfarin. The benefits of thromboprophylaxis and the risks of bleeding should be carefully evaluated and the dose of warfarin carefully adjusted. PMID:26522215

    Sclerosing encapsulating peritonitis (SEP) or abdominal cocoon is a rare acquired condition with an unknown aetiology. It is characterized by encapsulation of the small bowel by a fibrous membrane and can lead to intestinal obstruction. We present the case of a 42-year-old gentleman with a history of hepatitis C, tuberculosis, and previous abdominal surgery, who presented with subacute intestinal obstruction. Surgical exploration of the abdomen revealed that the entire contents were enclosed into three distinct sacs by a dense fibrous membrane. Excision of the sacs was performed followed by adhesiolysis. This is believed to be the first reported case of multiple cocoons within the abdominal cavity. The case is discussed with reference to the literature. PMID:25893128

    Cases of neonatal gastrointestinal system (GIS) obstruction are quite complex for pediatric surgery clinics. A rare cause of intestinal obstruction is the duplication cyst (DC). A three-day-old male patient presented at our clinic with a history of abdominal distension and bilious vomiting on the second day following birth. Although pathology had not yet been determined from observation and examination, surgery was performed when the patient could not tolerate oral feeding. An ileal DC forming an incomplete obstruction was observed. Ileoileal anastomosis was performed on the patient. Because DCs can present with different clinical symptoms, it is quite difficult to diagnose them in neonate patients. Lacking an imaging method that can provide an exact diagnosis, the diagnostic laparotomy is a suitable approach for both diagnosis and treatment to avoid delays in treatment. PMID:26294983

    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.

    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

    Congenital internal herniation is a rare condition presenting as recurrent abdominal pain or acute intestinal obstruction. In cases in which bowel incarceration or strangulation develop, rapid progression to bowel ischemia, necrosis or perforation is inevitable. Mortality in such cases has been reported to be as high as 50%. Despite advances in imaging modalities, arriving at a pre-operative diagnosis of a congenital internal herniation remains a challenge. We report such a case where imaging was unsuccessful in determining the cause of intestinal obstruction in a 3 year old child. Congenital internal herniation may result in disastrous consequences if not addressed in a timely fashion due to its rarity. Hence a high index of clinical suspicion is needed to avoid missing this diagnosis in a child presenting with recurrent abdominal pain or acute intestinal obstruction. PMID:22582563

    Chronic intestinal pseudo-obstruction (CIPO) is a syndrome characterized by recurrent clinical episodes of intestinal obstruction in the absence of any mechanical cause occluding the gut. There are multiple causes related to this rare syndrome. Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is one of the causes related to primary CIPO. MNGIE is caused by mutations in the gene encoding thymidine phosphorylase. These mutations lead to an accumulation of thymidine and deoxyuridine in blood and tissues of these patients. Toxic levels of these nucleosides induce mitochondrial DNA abnormalities leading to an abnormal intestinal motility.Herein, we described two rare cases of MNGIE syndrome associated with CIPO, which needed surgical treatment for gastrointestinal complications. In one patient, intra-abdominal hypertension and compartment syndrome generated as a result of the colonic distension forced to perform emergency surgery. In the other patient, a perforated duodenal diverticulum was the cause that forced to perform surgery. There is not a definitive treatment for MNGIE syndrome and survival does not exceed 40 years of age. Surgery only should be considered in some selected patients. PMID:21143863

    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.

    A loggerhead sea turtle (Caretta caretta) was suspected of ingesting rubber suction cups during rehabilitation following a cold-stun event. Survey radiographs were inconclusive. Computed tomography (CT) was performed to determine whether the objects had been ingested after traditional radiographs failed to resolve the material. The items were identified, and a partial obstruction was diagnosed. The case was managed with medical therapy using white petrolatum and light mineral oil administered to the turtle in fish for 3 wk. The CT exam was repeated 2 wk into the therapy. A persistent partial obstruction was identified; however, progression of the foreign objects through the intestinal tract was evident and continued medical mangement was deemed appropriate. The foreign bodies were passed with feces 26 days after ingestion. PMID:23805566

    Cisapride is a gastrointestinal prokinetic that facilitates or restores motility along the entire gastrointestinal tract. 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. PMID:22964344

    ABSTRACT Ureterocalycostomy can be performed in patients in whom desired methods of treating secondary PUJ (Pelvi-Ureteric Junction) obstructions either failed or could not be used. In our study, one child and two adults in whom one redo-ureterocalycostomy and two ureterocalycostomies were performed for severely scarred PUJ. 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. PMID:27286113

    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

    Multiple diverticulosis of jejunum represents an uncommon pathology of the small bowel. The disease is usually asymptomatic and must be taken into consideration in cases of unexplained malabsorption, anemia, chronic abdominal pain or discomfort. Related complications such as diverticulitis, perforation, bleeding or intestinal obstruction appear in 10-30% of the patients increasing morbidity and mortality rates. We herein report a case of a 55 year-old man presented at the emergency department with acute abdominal pain, vomiting and fever. Preoperative radiological examination followed by laparotomy revealed multiple giant jejunal diverticula causing intestinal obstruction. We also review the literature for this uncommon disease.

    Aim: This study was designed for clinical and laboratory evaluation of intestinal obstruction (IO) in buffaloes (Bubalus bubalis) with special emphasis on the diagnostic value of ultrasonographic findings. Materials and Methods: A total number of 30 buffaloes were included in the study and divided into 2 groups: Healthy (n=10) and diseased group (n=20). Diseased buffaloes were admitted to the Veterinary Teaching Hospital at Assiut University, Egypt, with a history of anorexia, abdominal pain, various degrees of abdominal distention, and absence or presence of scanty mucoid faces. These animals were subjected to clinical and ultrasonographic as well as laboratory examinations. Results: Based on ultrasonographic findings, various forms of IO were diagnosed. Functional obstruction, paralytic ileus, was diagnosed in 17 cases (85%) while mechanical IO was diagnosed only in 3 cases (15%). Out of 17 cases of paralytic ileus, both proximal and distal ileuses were successfully imaged in 8 and 9 cases, respectively. Proximal ileus was imaged from the right dorsal flank region as a single dilated loop of diameter >6 cm, while distal ileus was imaged as multiple dilated loops of diameter <6 cm. Mechanical obstruction due to duodenal intussusception was visualized as two concentric rings with outer echogenic wall and hypoechoic lumen. All cases of IO showed leukocytosis, hypoproteinemia, and increased activity of alkaline phosphatase and aspartate aminotransferase. Conclusion: Ultrasonography proved to be an essential tool for diagnosis and differential diagnosis of various forms of IO in buffaloes. PMID:27284223

    Intestinal malrotation occurs when there is a disruption in the normal embryological development of the bowel. The majority of patients present with clinical features in childhood, though rarely a first presentation can take place in adulthood. Recurrent bowel obstruction in patients with previous abdominal operation for midgut malrotation is mostly due to adhesions but very few reported cases have been due to recurrent volvulus. We present the case of a 22-year-old gentleman who had laparotomy in childhood for small bowel volvulus and then presented with acute bowel obstruction. Preoperative computerised tomography scan showed small bowel obstruction and features in keeping with midgut malrotation. Emergency laparotomy findings confirmed midgut malrotation with absent appendix, abnormal location of caecum, ascending colon and small bowel. In addition, there were small bowel volvulus and a segment of terminal ileal stricture. Limited right hemicolectomy was performed with excellent postoperative recovery. This case is presented to illustrate a rare occurrence and raise an awareness of the possibility of dreadful recurrent volvulus even several years following an initial Ladd’s procedure for midgut malrotation. Therefore, one will need to exercise a high index of suspicion and this becomes very crucial in order to ensure prompt surgical intervention and thereby preventing an attendant bowel ischaemia with its associated high fatality.

    The authors report a case of a 6-year-old girl who developed subacute intestinal obstruction after a trivial blunt trauma to her abdomen. Her normal vital signs masked the presence of intestinal bleeding. An incidental finding at surgery of a haematomatous polypoid vascular growth of the ileum was subsequently confirmed to be cavernous haemangioma of the small bowel. Surgical resection was curative in this patient. PMID:22679168

    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

    Several medications or their metabolites have been associated with urolithiasis, although overall they remain an infrequent cause of urolithiasis. Guaifenesin stones were originally reported as complexed with ephedrine, and subsequent reports have demonstrated pure guaifenesin stones, occurring after long term abuse. We report a case of a 23-year-old male who ingested a large, one time dose of guaifenesin, resulting in acute bilateral ureteral obstruction, which, to our knowledge, is the first such reported case in the literature.

    An intestinal obstruction occurs when either the small or large intestine is partly or completely blocked so it prevents passing the food or fluid through the small/large bowel. This blockage is due to the existence of a mechanical obstruction such as foreign material, mass, hernia, or volvulus. Common symptoms include cramping pain, nausea and vomiting, changes in bowel habits, inability to pass stool, and lack of gas. We present a case of an 83-year-old man who had been referred to Taleghani Hospital with symptoms of bowel obstruction. He underwent the surgery. The findings of exploration of the entire abdomen showed two types of mass separately in two different organs. In postoperative workup, pathology reported two types of tumors (adenocarcinoma and neuroendocrine tumors). PMID:27200205

    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

    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. PMID:27554826

    INTRODUCTION Midgut malrotation is a congenital anomaly presenting mainly in the childhood. Its presentation as an acute intestinal obstruction is extremely rare in adults usually recognized intra-operatively, therefore a high index of suspicion is always required when dealing with any case of acute intestinal obstruction. PRESENTATION OF CASE We report two cases of young adults who presented with symptoms of acute intestinal obstruction and were diagnosed intra-operatively as cecal volvulus and paraduodenal hernia, respectively, caused by midgut malrotation. Post-operative CT scan confirmed these findings. DISCUSSION Malrotation of the intestinal tract is a product of an aberrant embryology. The presentation of intestinal malrotation in adults is rare (0.2–0.5%). Contrast enhanced CT can show the abnormal anatomic location of a right sided small bowel, a left-sided colon and an abnormal relationship of the superior mesenteric vein (SMV) situated to the left of the superior mesenteric artery (SMA) instead of to the right. CONCLUSION Anomalies like midgut malrotation can present as an operative surprise and awareness regarding these anomalies can help surgeons deal with these conditions. PMID:23123419

    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. PMID:27264907

    A 34-year-old man with MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes) showed chronic intestinal pseudo-obstruction (CIPO), which was improved by the administration of distigmine bromide. He exhibited generalized tonic clonic seizures at the age of 21, and mitochondrial DNA analysis showed the MELAS mutation. At the age of 34, he became akinetic mutism after nonconvulsive status epilepticus and needed enteral nutrition through a nasogasrtic tube. However, he developed abdominal distention and vomiting, and was diagnosed as CIPO, therefore tube feeding was stopped. Although the administration of domperidone, mosapride citrate, butyric acid bacteria, sodium picosulfate, prostaglandin F2 alpha, pantothenic acid, dioctyl sodium sulfosuccinate, and so on, was ineffective, the administration of distigmine bromide improved his bowel motion disturbance and abnormal distention. The present case is the first MELAS patient with CIPO to be ameliorated by distigmine bromide, which might work acetylcholine receptor on the interstitial cells of Cajal. PMID:17511291

    Sclerosing encapsulating peritonitis (SEP) is a rare cause of intestinal obstruction that is characterized by a thick fibrotic membrane encasing the small intestine like a cocoon. Accurate preoperative diagnosis is often difficult. We present 2 cases of SEP that were diagnosed preoperatively by contrast-enhanced computed tomography scan. A 38-year-old man and a 56-year-old woman were admitted to Daegu Catholic University Medical Center because of recurrent intestinal obstruction. We performed exploratory laparotomy with doubt of the preoperative diagnosis of SEP. We confirmed the diagnosis of SEP on laparotomy and performed adhesiolysis. Both patients recovered successfully and had no signs of recurrence. A better awareness of SEP and its radiological features should lead to more correct preoperative diagnosis and result in more appropriate management, including surgery. PMID:27073795

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. PMID:26078585

    Abstract We reported on 1 case of epithelioid inflammatory myofibroblastic sarcoma (EIMS) that occurred in the colon and resulted in an incomplete intestinal obstruction. A 65-year-old male patient presented with abdominal pain without any obvious predisposing cause. He reported a paroxysmal dull pain. Hematochezia occurred occasionally. The symptoms appeared repeatedly and became progressively more aggravated. The patient sought medical advice in our hospital, and his enteroscopy showed colon tumors and an incomplete colonic obstruction. The laboratory examination indicated mild anemia. Plain and enhanced computed tomography (CT) scans showed a large, dumbbell-shaped, soft-tissue mass of 4.1 cm × 9.3 cm in the curved lumen of the descending colon near the spleen. After enhancement, the lesion presented with progressive and uneven enhancement. The boundary between the lesion and parts of the left kidney and spleen was obscured. A small amount of exudation was observed around the lumen, and a slightly enlarged lymph node shadow was observed in the mesangial gap. After each preoperative examination was completed, the tumors invading the spleen and left kidney were excised. Based on the surgical specimen pathological histology and immunohistochemistry, epithelioid inflammatory myofibroblastic sarcoma was diagnosed. Tumor recurrence occurred a short time after excision. EIMS in the abdominal cavity could occur on the intestinal wall, occasionally manifesting as large masses that expand to the inside and the outside of the cavity. It needs to be distinguished from other tumors. Tumor recurrence can easily occur after surgery. Anaplasticlymphoma kinase (ALK) inhibitors are a potential alternative treatment option.

    Although many people have Meckel's diverticulum, only some experience any symptoms, most under the age of 10. In adults it is usually asymptomatic but approximately 4% develop complications. Meckel's diverticulum is usually diagnosed in the first years of life and after that the risk of the complications decreases with increasing age, with no predictive factors for the development of complications. We describe the case of a 34-year-old man admitted in the emergency department with diffuse abdominal pain, nausea, flatulence and lack of transit for feces and gas. The patient had been previously operated for peritonitis due to a perforated ulcer. Clinical examination and paraclinical investigations (abdominal radiography and ultrasound) suggested the diagnosis of intestinal obstruction, probably produced by adhesions due to previous abdominal intervention. The diverticulum was resected using a linear stapler and the patient recovered without any complications. Small bowel obstruction due to Meckel's diverticulitis may be caused by entangled loop of small bowel around a fibrous cord, intussusception, volvulus, or incarceration within a hernia sac. The discovery of a Meckel's diverticulum complication in a mid thirties patient represented an intra-operatory surprise and is the peculiarity of the case. PMID:25970960

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. Physical examination revealed bloating, absence of bowel sounds, abdominal tenderness, and a palpable mass in right hemi-abdomen. Abdominal radiographs showed air-fluid levels with mild bowel distention and shadows of roundworms. The diagnosis of IO by A lumbricoides. infestation was established and surgical approach scheduled. During exploratory laparotomy an intraluminal bolus of roundworms from jejunum to ascendant colon was evident. An ileum enterotomy was performed and worms were removed. Fluid therapy and antibiotics for 72 hours were administered, with posterior albendazol treatment for 3 days. Patient was uneventfully discharged on the tenth day. Reduction in parasitic load by means of improvements in sanitation, health education, and anthelmintic treatment must be implemented in endemic zones to prevent serious life-threatening complications by A lumbricoides. infestation, because some of them require urgent surgical treatment.

    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.

    2016-01-01

    Introduction Desmoid tumours (DTs) are rare, soft tissue tumours which account for 0.03% of all neoplasms. They are characteristically locally invasive but do not metastasize. There is frequent association with females of reproductive age, a history of abdominal surgery or trauma and a family history of fibromatoses. Intra-abdominal DTs are infrequently sporadic and more commonly associated with inherited disorders such as familial adenomatous polyposis (FAP), attenuated FAP and Gardener’s syndrome. Presentation of case The authors report a rare case of small bowel obstruction and perforation secondary to sporadic, synchronous intra-abdominal DTs in a 54-year old man with atypical symptoms and no risk factors or family history. Discussion Intra-abdominal DTs have a worse prognosis as they can cause intestinal bleeding, obstruction and perforation. Due to the rarity of these tumours there are no clear guidelines on their management and this is instead based on small case series from specialist centres. In the non-acute setting patients with sporadic intra-abdominal DTs should be managed in a specialist sarcoma unit by a multidisciplinary team. In the presence of FAP or other polyposis syndromes patients with DTs should be managed at a specialist colorectal unit. Emergent presentations require emergency surgery in suitable candidates. Conclusion In non-emergency presentations of DTs, it is essential to exclude FAP, AFAP and other hereditary polyposis syndromes since this affects treatment and subsequent follow-up. PMID:26866881

    The central alveolar hypoventilation of Ondine's curse is a disorder characterized by absent or diminished ventilatory response to hypercapnia, hypoxia or both, with parallel decrease in saturation to 50%. The secondary form may begin mainly after insult that affects the brain stem. We present a case of a 24-years old primipara in the 41st gestational week with an uncomplicated course of pregnancy and with secondary non-obstructive sleeping hypoventilation which occurred after eclamptic seizure. This obstetric case provides evidence for the benefit of home BiPAP use for patients with secondary Ondine's curse. PMID:25723073

    Purpose For adult survivors of childhood cancer, knowledge about the long-term risk of intestinal obstruction from surgery, chemotherapy, and radiotherapy is limited. Methods Intestinal obstruction requiring surgery (IOS) occurring 5 or more years after cancer diagnosis was evaluated in 12,316 5-year survivors in the Childhood Cancer Survivor Study (2,002 with and 10,314 without abdominopelvic tumors) and 4,023 sibling participants. Cumulative incidence of IOS was calculated with second malignant neoplasm, late recurrence, and death as competing risks. Using piecewise exponential models, we assessed the associations of clinical and demographic factors with rate of IOS. Results Late IOS was reported by 165 survivors (median age at IOS, 19 years; range, 5 to 50 years; median time from diagnosis to IOS, 13 years) and 14 siblings. The cumulative incidence of late IOS at 35 years was 5.8% (95% CI, 4.4% to 7.3%) among survivors with abdominopelvic tumors, 1.0% (95% CI, 0.7% to 1.4%) among those without abdominopelvic tumors, and 0.3% (95% CI, 0.1% to 0.5%) among siblings. Among survivors, abdominopelvic tumor (adjusted rate ratio [ARR], 3.6; 95% CI, 1.9 to 6.8; P < .001) and abdominal/pelvic radiotherapy within 5 years of cancer diagnosis (ARR, 2.4; 95% CI, 1.6 to 3.7; P < .001) increased the rate of late IOS, adjusting for diagnosis year; sex; race/ethnicity; age at diagnosis; age during follow-up (as natural cubic spline); cancer type; and chemotherapy, radiotherapy, and surgery within 5 years of cancer diagnosis. Developing late IOS increased subsequent mortality among survivors (ARR, 1.8; 95% CI, 1.1 to 2.9; P = .016), adjusting for the same factors. Conclusion The long-term risk of IOS and its association with subsequent mortality underscore the need to promote awareness of this complication among patients and providers. PMID:26261256

    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.

    The duodenal injuries occur in the 3-5% of blunt abdominal traumas. The isolated intramural duodenal hematoma is a very rare lesion. An early diagnosis and an adequate therapy are crucial because a delay, beyond 24 hours, increases the mortality from the 11% to 40%. However, diagnosis is often hindered by a lack of specific symptoms. We report a case of a 21 years-old man with an intestinal obstruction from isolated intramural duodenal hematoma occurred after a blunt abdominal trauma in a sport competition. The patient was treated conservatively with total parenteral nutrition, gastric decompression and intravenous PPIs. The progressive spontaneous resolution of the hematoma was checked with periodical endoscopies. The discharge occurred after three weeks with no early complications. No late complications occurred at one-year follow-up. The endoscopy is a good and safe tool in the management of this intestinal obstructions with the possibility of conservative or interventional treatment. PMID:26675664

    Complex regional pain syndrome (CRPS) is evoked by conditions that may be associated with local and/or systemic inflammation. We present a case of long-standing CRPS in a patient with Ehlers-Danlos syndrome in which prolonged remission was attained by directing therapy toward concomitant small intestinal bacterial overgrowth, obstructive sleep apnea, and potential increased microglia activity. We theorize that cytokine production produced by small intestinal bacterial overgrowth and obstructive sleep apnea may act as stimuli for ongoing CRPS symptoms. CRPS may also benefit from the properties of low-dose naltrexone that blocks microglia Toll-like receptors and induces production of endorphins that regulate and reduce inflammation. PMID:26867023

    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. PMID:25199187

    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

    Intestinal malrotation is a congenital abnormality and is rarely seen in the adulthood. Most adult cases would be classified to the non-rotation type with Ladd's band and Ladd procedure is the treatment of choice. A 66 year-old woman admitted to our hospital due to duodenum obstruction. Several tests revealed that she had intestinal malrotation previously undiagnosed. Operative findings showed the fusion of duodenum with jejunum by the incomplete Treitz ligament. There was no Ladd's band and the right colon was unfixed. Dissection of the fusion completely released her symptom and she discharged without any complication. This is the first report of untypically intestinal malrotation in the adulthood without Ladd's band. PMID:24693686

    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

    AIM: To reveal the frequency, characteristics and prog-nosis of chronic intestinal pseudo-obstruction (CIP) in mitochondrial disease patients. METHODS: Between January 2000 and December 2010, 31 patients (13 males and 18 females) were diagnosed with mitochondrial diseases at our hospital. We conducted a retrospective review of the patients’ sex, subclass of mitochondrial disease, age at onset of mitochondrial disease, frequency of CIP and the age at its onset, and the duration of survival. The age at onset or at the first diagnosis of the disorder that led to the clinical suspicion of mitochondrial disease was also examined. RESULTS: Twenty patients were sub-classified with mitochondrial encephalopathy with lactic acidosis and stroke-like episodes (MELAS), 8 with chronic progressive external ophthalmoplegia (CPEO), and 3 with myoclonus epilepsy associated with ragged-red fibers (MERRF). Nine patients were diagnosed with CIP, 8 of the 20 (40.0%) patients with MELAS, 0 of the 8 (0.0%) patients with CPEO, and 1 of the 3 (33.3%) patients with MERRF. The median age (range) at the diagnosis and the median age at onset of mitochondrial disease were 40 (17-69) and 25 (12-63) years in patients with CIP, and 49 (17-81) and 40 (11-71) years in patients without CIP. During the survey period, 5 patients (4 patients with MELAS and 1 with CPEO) died. The cause of death was cardiomyopathy in 2 patients with MELAS, cerebral infarction in 1 patient with MELAS, epilepsy and aspiration pneumonia in 1 patient with MELAS, and multiple metastases from gastric cancer and aspiration pneumonia in 1 patient with CPEO. CONCLUSION: Patients with CIP tend to have disorders that are suspected to be related to mitochondrial diseases at younger ages than are patients without CIP. PMID:22969229

    Off-site consultations by board-certified veterinary radiologists benefit residents and emergency clinicians by providing immediate feedback and potentially improving patient outcome. Smartphone devices and compressed images transmitted by email or text greatly facilitate availability of these off-site consultations. Criticism of a smartphone interface for off-site consultation is mostly directed at image degradation relative to the standard radiographic viewing room and monitors. The purpose of this retrospective, cross-sectional, methods comparison study was to compare the accuracy of abdominal radiographs in two imaging interfaces (Joint Photographic Experts Group, off-site, smartphone vs. Digital Imaging and Communications in Medicine, on-site, standard workstation) for the diagnosis of small intestinal mechanical obstruction in vomiting dogs and cats. Two board-certified radiologists graded randomized abdominal radiographs using a five-point Likert scale for the presence of mechanical obstruction in 100 dogs or cats presenting for vomiting. The area under the receiver operator characteristic curves for both imaging interfaces was high. The accuracy of the smartphone and traditional workstation was not statistically significantly different for either reviewer (P = 0.384 and P = 0.536). Correlation coefficients were 0.821 and 0.705 for each reviewer when the same radiographic study was viewed in different formats. Accuracy differences between radiologists were potentially related to years of experience. We conclude that off-site expert consultation with a smartphone provides an acceptable interface for accurate diagnosis of small intestinal mechanical obstruction in dogs and cat. PMID:27356300

    We report the case of a 7-year-old girl with intestinal obstruction due to post-traumatic intramural duodenal hematoma. She had fallen from the monkey bars the day before presenting to our hospital, and was admitted with signs of abdominal pain, vomiting, and nausea. Abdominal ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) demonstrated a heterogeneous solid mass located within the duodenal wall, compressing the descending part of the duodenum. The inferior vena cava was also compressed by the mass lesion, although no associated symptoms were evident. Based on these findings, the mass lesion was considered to represent intramural hematoma causing intestinal obstruction. She was managed conservatively with total parenteral nutrition. Although CT and MRI are useful for differentiating hematoma from other intestinal tumors, ultrasonography is minimally invasive and easier to perform repeatedly. In case of duodenal hematoma, ultrasonography may be quite helpful for diagnosis and follow-up by monitoring tumor size and characteristics, and the degree of duodenal compression during conservative treatment.

    Summary Background Stent insertion is widely performed to restore biliary drainage in hepatic, biliary, and pancreatic obstructive conditions. Intestinal perforation due to the migration of these stents is an extremely rare late-term complication that is associated with a high rate of mortality. The current report aimed at presenting the radiological findings of a case of extraluminal biliary stent migration into the pelvic region that caused intestinal perforation. Case Report We report a case of an 85-year-old male with a history of previous stent insertion who presented with a sudden – onset severe abdominal pain. An abdominal multidetector computed tomography (MDCT) revealed a tubular foreign body density, compatible with intestinal perforation due to migration of the biliary stent. Conclusions Biliary stent insertion becomes a more common procedure. This serious complication must always be remembered in patients presenting with abdominal pain after stent insertion.

    A 68-year-old man with episodes of overt obscure gastrointestinal (GI) bleeding was investigated with multiple upper and lower GI endoscopies, CT enterography and capsule endoscopy, but no cause was found. He then presented acutely with small bowel obstruction. A laparotomy revealed complete small bowel obstruction secondary to jejunal intussusception over a 4 cm intraluminal polyp. Following resection and primary anastomosis, histology revealed that the polyp was a GI stromal tumour (GIST). This is an exceptionally uncommon presentation of a rare tumour. It is surprising that this tumour was not detected by CT enterography and not seen on capsule endoscopy. Immunohistochemistry and mutation analysis of the GIST suggested that it had a low risk of metastatic disease, but a high risk of recurrence. Staging CT scans did not reveal evidence of distal spread. The patient is currently receiving 3 years of chemotherapy with imatinib. PMID:26527610

  1. Precipitous intussusception with anal protrusion and complete overt rectal prolapse presenting with intestinal obstruction and an associated rectal adenoma in a young man: a case report

    PubMed Central

    2013-01-01

    Background Intestinal obstruction secondary to intussusception, occurring simultaneously with complete rectal prolapse, is an unusual entity among young adults. When it occurs the intussusceptum may protrude per anus. Few cases are cited in literature; each with a unique clinical presentation. There is apparently no uniform trend in its clinical and pathological picture. Case presentation A 38-year-old, African-Ugandan man presented with sudden occurrence of rectal prolapse for one day. He had otherwise been in good health. Symptoms were precipitous. A clinical diagnosis of intussusception of the lower gut with rectal prolapse, and intestinal obstruction, was made. The intussusception was found to have a polyp as the ‘lead point’. He was treated by manual reduction of the intussusception and the prolapse under general anesthesia. Histopathologic examination of the polyp showed it to be an adenoma. Definitive surgical treatment of the patient was not completed due to socioeconomic challenges. Conclusions Rectal prolapse and intussusception are commonly childhood conditions. Rectal prolapse alone is commoner in the middle-aged and elderly; females in particular. The finding of this combined clinical entity in a young, adult male is therefore a unique condition with an unusual presentation. It is the first case of its kind reported in East Africa. It is also an example of an adenoma constituting a ‘lead point’ for an intussusception at the gastrointestinal tract’s terminus. Even in the presence of a pre-existing adenoma, a relatively common lesion, other differential diagnoses acting as ‘lead points’ ought to be considered in perspective. This characteristic, along with other features described in this case, is useful knowledge for colorectal surgeons, general surgeons, gastrointestinal pathologists, and gastroenterologists given their involvement in the diagnosis and management of anorectal disease of peculiar presentation.

    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. PMID:26493622

    A 47-year-old woman with ulcerative colitis (UC) was admitted to our hospital for renal dysfunction and progressive anemia. Colonoscopy revealed intestinal lesions and pathological findings showed intravascular large B-cell lymphoma (IVLBCL). According to the polymerase chain reaction analysis of sequential rectal specimens, we concluded that she suffered from intestinal BCL, not UC. After chemotherapy, her renal function progressed to nephrotic syndrome. The pathological findings of renal biopsy specimens indicated membranoproliferative glomerulonephritis (MPGN). Chemotherapy was continued and led to the remission of BCL and MPGN. We herein describe the first case of intestinal IVLBCL mimicking UC with secondary MPGN. PMID:27580553

    Although the etiology of lower urinary tract symptoms (LUTS) is often multifactorial, a significant proportion of men over the age of 50 suffer from benign prostatic obstruction (BPO) secondary to benign prostatic hyperplasia. Prostate, being an androgen responsive organ is dependent on the male sex hormone, testosterone, for growth. Thus, treatment strategies that manipulate the levels of circulating hormones that influence the level of testosterone and/or prostatic growth represent an important potential option for patients suffering with troublesome LUTS due to BPO. Despite this, the only hormonal treatment that is currently used in daily clinical practice is the 5-alpha reductase inhibitor. In this article, we review the current evidence on the use of the 5-alpha reductase inhibitors finasteride and dutasteride. We also discuss new emerging hormonal manipulation strategies for patients with LUTS secondary to BPO. PMID:24744519

    Intussusception is a rare cause of postoperative intestinal obstruction in adults. We experienced two cases of bowel obstruction due to the jejuno-jejunal intussusception after harvest of a free jejunum graft for reconstruction after cervical esophagectomy. Bowel obstruction occurred early in the postoperative course, and reoperations were needed in both cases. In both case, the anastomotic site was resected and re-anastomosed in a side-to-side fashion. Recurrence of intussusception has not been observed. In the literature, such a complication has been documented in two case series and a case report. The reported incidence of postoperative intussusception of the case series was 2.8% and 7.4%, respectively. The jejuno-jejunal anastomoses were performed with end-to-end fashion by two layered hand-sewn suture (Albert-Lembert method) in all cases reported. In order to prevent the occurrence of postoperative intussusception, we recommend to harvest a free jejunal graft as far from the Treitz ligament as possible and to avoid reconstruction by an Albert-Lembert end-to-end anastomosis.

    AIM: To investigate the long-term follow-up of distal intestinal obstruction syndrome (DIOS) in Israeli cystic fibrosis (CF) patients. METHODS: This is a multi-center, comparative, retrospective study in which we reviewed the medical records of all CF patients from three major CF centers in Israel who were treated in the period from 1980 to 2012. Patients diagnosed with DIOS were defined as the study group. The patients were diagnosed with DIOS based on their clinical presentation and typical findings on either abdominal X-ray or computerized tomography scan. For the control group, CF patients with no DIOS were matched to the patients in the study group for age, sex, and cystic fibrosis transmembrane conductance regulator (CFTR) mutations. For both groups, the collected data included age, sex, CFTR genotype, weight, height, and body mass index. Clinical data included respiratory function tests in the last five years prior to the study, respiratory function test immediately before and after the DIOS event, number of hospitalizations, sputum culture results, and CF-related conditions diagnosed according to the CF clinical practice guidelines. In the study group, data on the DIOS treatment and tendency for DIOS recurrence were also analyzed. RESULTS: The medical charts for a total of 350 CF patients were reviewed. Of the 350 CF patients, 26 (7.4%) were diagnosed with DIOS. The control group included 31 CF patients with no DIOS diagnosis. The mean follow-up period was 21.6 ± 8.2 years. The total of DIOS episodes in the follow-up period was 60. The distribution of DIOS episodes was as follows: 6/26 (23.1%) study patients had one episode of DIOS in their lifetime, 7/26 (26.9%) had two episodes, 7/26 (26.9%) had three episodes, and 6/26 (23.1%) had four or more episodes. Compared to the control group, DIOS patients had a significantly higher incidence of meconium ileus in the past (65.4% vs 0%, respectively, P < 0.02), more Aspergillus spp. colonization (34.6% vs 3

    Numerous medical disorders, including obstructive sleep apnea, may cause nocturnal diaphoresis. Previous work has associated severe obstructive sleep apnea with nocturnal diaphoresis. This case report is of import as our patient with severe nocturnal diaphoresis manifested only mild sleep apnea, and, for years, his nocturnal diaphoresis was ascribed to other causes, i.e., first prostate cancer and then follicular B-cell lymphoma. Additionally, it was the nocturnal diaphoresis and not more common symptoms of obstructive sleep apnea, such as snoring, that led to the definitive diagnosis of his sleep apnea and then to treatment with a gratifying resolution of his onerous symptom.

    Gastrointestinal (GI) symptoms are common in patients with systemic lupus erythematosus (SLE) and may be due to the disease itself, side-effects of medications, or non-SLE causes. However, GI manifestations of lupus attract far less attention than the other major organ involvements, are infrequently reviewed and rarely documented in published lupus databases or cohort studies including those from countries in Asia. According to three reports from two countries in Asia, the cumulative prevalence of SLE GI manifestations range from 3.8% to 18%. In this review, we focus on three major GI manifestations in patients from Asian countries: lupus enteritis, intestinal pseudo-obstruction, and protein-losing gastroenteropathy, for which early recognition improves outcome and reduces morbidity and mortality.

    A solitary small intestinal ulcer associated with a carcinoid tumour in a nearby Meckel's diverticulum was found in a 77 year old man presenting with massive rectal bleeding. Angiography and a radioisotope study localised the bleeding to the ileum. At operation, the Meckel's diverticulum was identified, with bleeding from an ulcer just distal to it. Pathological examination revealed a small carcinoid tumour confined to the Meckel's diverticulum. Close to the opening of the diverticulum, within the ileum, a well demarcated ulcer was present. Histology showed a non-specific ulcer which eroded a large blood vessel. This is the first documented occurrence of solitary small intestinal ulceration in association with a carcinoid tumour. Carcinoid tumour should be added to the list of possible causes of small intestinal ulceration. The ulceration may be secondary to release of cytokines by the tumour. Images PMID:10343617

    We reported on 1 case of epithelioid inflammatory myofibroblastic sarcoma (EIMS) that occurred in the colon and resulted in an incomplete intestinal obstruction.A 65-year-old male patient presented with abdominal pain without any obvious predisposing cause. He reported a paroxysmal dull pain. Hematochezia occurred occasionally. The symptoms appeared repeatedly and became progressively more aggravated. The patient sought medical advice in our hospital, and his enteroscopy showed colon tumors and an incomplete colonic obstruction. The laboratory examination indicated mild anemia. Plain and enhanced computed tomography (CT) scans showed a large, dumbbell-shaped, soft-tissue mass of 4.1 cm × 9.3 cm in the curved lumen of the descending colon near the spleen. After enhancement, the lesion presented with progressive and uneven enhancement. The boundary between the lesion and parts of the left kidney and spleen was obscured. A small amount of exudation was observed around the lumen, and a slightly enlarged lymph node shadow was observed in the mesangial gap.After each preoperative examination was completed, the tumors invading the spleen and left kidney were excised. Based on the surgical specimen pathological histology and immunohistochemistry, epithelioid inflammatory myofibroblastic sarcoma was diagnosed. Tumor recurrence occurred a short time after excision.EIMS in the abdominal cavity could occur on the intestinal wall, occasionally manifesting as large masses that expand to the inside and the outside of the cavity. It needs to be distinguished from other tumors. Tumor recurrence can easily occur after surgery. Anaplasticlymphoma kinase (ALK) inhibitors are a potential alternative treatment option.

    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. PMID:26755265

    Myeloperoxidase (MPO) is a specific enzyme of neutrophil azurophilic granules with a strong oxidative activity. Thanks to a radioimmunoassay of equine myeloperoxidase, the authors have observed a significantly higher plasma level of MPO in horses operated for strangulation obstruction of the large intestine (n = 6) than in horses suffering from a non-strangulating displacement of the large intestine (n = 9). For the 2 groups, 3 phases were distinguished: reception (P1), intensive care (P2) and terminal phase (P3). The mean peak values of MPO for these phases were 121.6 ng/mL (P1), 168.6 ng/mL (P2), and 107.0 ng/mL (P3) for the non-strangulating group, and 242.6 ng/mL (P1); 426.0 ng/mL (P2), and 379.5 ng/mL (P3) for the strangulation group. The variations of the mean peak values of plasma MPO were significantly different between the 2 groups and between the different phases. A significant increase of the least square means of MPO was observed between P1 and P2. A significant decrease of the least square means of the number of circulating leukocytes was observed between P1 and P3. Polymorphonuclear neutrophil activation could play a major role in the pathogenesis of acute abdominal disease and endotoxic shock. PMID:10369573

    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. Physical examination revealed bloating, absence of bowel sounds, abdominal tenderness, and a palpable mass in right hemi-abdomen. Abdominal radiographs showed air-fluid levels with mild bowel distention and shadows of roundworms. The diagnosis of IO by A lumbricoides. infestation was established and surgical approach scheduled. During exploratory laparotomy an intraluminal bolus of roundworms from jejunum to ascendant colon was evident. An ileum enterotomy was performed and worms were removed. Fluid therapy and antibiotics for 72  hours were administered, with posterior albendazol treatment for 3 days. Patient was uneventfully discharged on the tenth day.Reduction in parasitic load by means of improvements in sanitation, health education, and anthelmintic treatment must be implemented in endemic zones to prevent serious life-threatening complications by A lumbricoides. infestation, because some of them require urgent surgical treatment.

    Superior Mesenteric Artery (SMA) syndrome is one of the rare cause of proximal small bowel obstruction wherein, the third part of the duodenum is compressed between the SMA at its origin and abdominal aorta due to decreased angulations in these two vessels. This decreased angulation exerts a compression effect on third part of the duodenum, resulting in duodenal obstruction which may be complete or partial. There are number of causes which can lead to this entity and will be discussed briefly. Here we report imaging findings of such a rare cause of proximal small bowel obstruction in a young male patient who presented to the emergency surgical department with non specific symptoms of pain abdomen and abdominal fullness. Patient was evaluated under the standard protocol in management of abdominal pain. General physical examination, erect and supine radiograph were taken. On barium meal follow-through examination, there was paucity of contrast agent distal to the second part of duodenum with proximal dilation of stomach, first and second part of duodenum which raised us the possibility of SMA syndrome. Reconstructed CECT abdomen confirmed the decreased angulation between SMA and abdominal aorta and diagnosed it as SMA syndrome. Findings were correlated on duodenojejunostomy anastomotic surgical procedure. Diagnosing and reporting such a case of SMA syndrome is of utmost importance because the clinical presentation being non-specific pertaining to small bowel obstruction which may pose a diagnostic difficulty to the surgeon and with the further delay in diagnosis, patients may end up with chronic symptoms and complications of the disease, repeated hospital visits and electrolyte abnormalities.

    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.

    Primary CIPSO involves ileus symptoms without mechanical occlusion; these are caused by absence or ineffectiveness of peristalsis despite normal intestinal wall structure. The neonatal and adult types are differentiated. Ileus is progressive in the neonatal clinical pictures of CIPSO (neonatal CIPSO, MMIHS, congenital short-bowel syndrome) and chronic in the adult type, where it is also ultimately fatal, however. The problems of diagnosis and therapy are discussed and demonstrated in 5 children with primary CIPSO. PMID:3431298

    Introduction Small bowel adenocarcinoma is a rare entity most frequently observed with celiac disease. This is the first case report on the association of celiac disease, small bowel adenocarcinoma and intestinal malrotation. Case report A 40 year-old male patient diagnosed with celiac disease since the age of 5 years complained of epigastric pain and vomiting for three days. Computed tomography (CT) showed a significant gastroduodenal dilatation with thickened intestinal wall proximal to the duodenojejunal flexure. The lumen contained a food bezoar in the center. The duodenojejunal angle was abnormally on the right side of the abdomen and the superior mesenteric vein was anterior to the superior mesenteric artery. Endoscopy after aspiration found a hemi-circumferential and irregular mass which bled at the contact of fibroscope. Biopsies showed an adenocarcinoma and small bowel resection was performed. Discussion Celiac disease is associated with a high risk of small bowel cancer. The association of incomplete intestinal malrotation, duodenojejunal flexure tumor and celiac disease made the surgery challenging. Conclusion Patients with celiac disease should be carefully monitored and endoscopic or radiologic investigations should be carried out in patients with any doubtful symptoms. PMID:26670410

    A 5 day old baby, with known left hydronephrosis which discovered by prenatal US presented with gastrointestinal tract obstruction. Laboratory work up demonstrated abnormal renal function and metabolic acidosis combined with hyperkalemia. Radiology tests showed bilateral hydronephrosis with huge left renal pelvis crossing the midline and causing deviation of the gut laterally. This acute presentation beside inability to receive oral feeding made us prefer immediate left renal drainage with pyelostomy in order to restore renal function, relieve the pressure effect of the huge renal pelvis and stabilize the baby. Dismembered pyeloplasty was done at age of 3 months. PMID:27313982

    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. PMID:21318994

    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. PMID:24777424

    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.

    Abstract Background: Obstructing ureteral stones are a rare cause of anuria, which is typically from prerenal or renal etiologies. Classically, obstructive stones cause moderate to severe renal colic. Urolithiasis is rarely considered during evaluation of painless anuria. Case Presentation: We present an unusual case of a 73-year-old Caucasian female who presented with anuria and was found to have large bilateral obstructing ureteral stones in the absence of renal colic. Conclusion: Given that patients with obstructive anuria can be asymptomatic, urolithiasis should be considered in all patients presenting with anuria. PMID:27579429

All elephants showed some evidence of discomfort including agitation, vocalization, or postural changes. One animal had abnormal rectal findings. Nonmotile bowel loops were seen on transabdominal ultrasound in another case. Duration of signs ranged from 6 to 36 hr. All elephants received analgesics and were given oral or rectal fluids. Other treatments included warm-water enemas or walking. One elephant underwent exploratory celiotomy. Three animals died, and the elephant taken to surgery was euthanized prior to anesthetic recovery. At necropsy, all animals had severe, strangulating intestinal lesions. PMID:22448519

    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. PMID:26689254

    Objective To analyze plasma myostatin levels and investigate their relationship with right ventricular (RV) function in patients with cor pulmonale secondary to chronic obstructive pulmonary disease (COPD). Methods The study recruited 81 patients with advanced COPD and 40 age-matched controls. The patients were divided into two groups: those with cor pulmonale and those without. Echocardiography was used to evaluate RV function and morphology, and the value of tricuspid annular plane systolic excursion (TAPSE) less than 16 mm was considered RV dysfunction. Plasma myostatin levels were analyzed by enzyme-linked immunosorbent assay, and B-type natriuretic peptide (BNP) levels were analyzed as a comparison of myostatin. Results The data detected cor pulmonale in 39/81 patients, with the mean value of TAPSE of 14.3 mm. Plasma myostatin levels (ng/mL) were significantly higher in patients with cor pulmonale (16.68 ± 2.95) than in those without (13.56 ± 3.09), and much higher than in controls (8.79±2.79), with each p<0.01. Significant differences were also found in plasma BNP levels among the three groups (p<0.05). Multivariate regression analysis suggested that myostatin levels were significantly correlated with the values of TAPSE and RV myocardium performance index among the COPD patients, and that BNP levels were significantly correlated only with systolic pulmonary arterial pressure, with each p<0.05. Conclusions Plasma myostatin levels are increased in COPD patients who have cor pulmonale. Stronger correlations of plasma myostatin levels with echocardiographic indexes of the right heart suggest that myostatin might be superior to BNP in the early diagnosis of cor pulmonale in COPD.

    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.

    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

    Abstract The objective of this article is to investigate the clinical features of intestinal pseudo-obstruction (IPO) and/or ureterohydronephrosis in systemic lupus erythematosus (SLE). Sixty-one SLE patients with IPO and/or ureterohydronephrosis were analyzed retrospectively. A total of 183 cases were randomly selected as controls from 3840 SLE inpatients without IPO and ureterohydronephrosis during the same period. Patients were assigned to 1 of the 3 groups (SLE with IPO and ureterohydronephrosis, SLE with IPO, and SLE with ureterohydronephrosis). The clinical characteristics, treatments, and prognosis were compared between the 3 groups. There were 57 females and 4 males, with a mean age of 32.0 years. IPO was the initial manifestation of SLE in 49.1% of the cases, whereas ureterohydronephrosis in 32.5%. All patients were initially treated with a high-dose steroid. Thirty-one of these patients (50.8%) also received intravenous methylprednisolone pulse therapy. Two patients died of bowel perforation and lupus encephalopathy, and the other 59 patients (96.7%) achieved remission after treatment. The incidences of fever, glomerulonephritis, nervous system involvement, serositis, erythrocyte sedimentation rate elevation, hypoalbuminemia, hypocomplementemia, and anti-SSA antibody positivity were significantly higher in patients with IPO and/or ureterohydronephrosis than in the control group (without IPO and ureterohydronephrosis). Also, patients with IPO and/or ureterohydronephrosis had higher SLE Disease Activity Index scores than control patients. Compared with SLE patients with IPO, the patients with IPO and ureterohydronephrosis had a significantly higher incidence of gallbladder wall thickening, biliary tract dilatation, and serositis, whereas the patients with ureterohydronephrosis had less mucocutaneous involvement and serositis. Eight of the 47 IPO patients who initially responded well to immunotherapy relapsed; however, all responded well to retreatment with

    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.

    A 13-year-old, 25-kg, castrated male border collie was referred for evaluation of pollakiuria, stranguria, and a decreased urine stream. A calcified periurethral mass near the caudal aspect of the os penis was identified on survey abdominal radiographs. A retrograde contrast urethrocystogram demonstrated that the mass was compressing the penile urethra. The mass was surgically resected. A histopathological diagnosis of an ossifying fibroma of the os penis was made. This report describes an atypical presentation of a rare tumor, an ossifying fibroma, that caused a urinary obstruction in a male dog. A review of the incidence, histopathological features, and behavior of ossifying fibromas is included. PMID:15007052

    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

    An 8-yr-old male buff-cheeked gibbon (Nomascus gabriellae) acutely developed abnormal behavior, decreased appetite, and dull mentation. Mild generalized muscle wasting and weight loss were the only other abnormalities noted on examination. Routine immunodiffusion serology for Coccidioides spp. were IgG and IgM positive. Magnetic resonance imaging of the brain was suggestive of an infectious meningoencephalitis with secondary obstructive hydrocephalus. A ventriculoperitoneal shunt was placed in standard fashion to reduce the imminent risk of mortality from increased intracranial pressure. Postoperative treatment included oral fluconazole, a tapered course of prednisolone, and physical therapy. Clinical signs improved steadily and the gibbon was fit to return to exhibit 8 wk post-shunt placement. This case of coccidioidomycosis demonstrates the complications that can occur with dissemination to the central nervous system and its management. It is the first published report describing the use of ventriculoperitoneal shunt placement in this species. PMID:24063114

  3. Isolated liver transplantation for treatment of liver failure secondary to intestinal failure

    Intestinal Failure is a permanent loss of digestive and absorptive functions as a consequence of short bowel syndrome and/or other primary intestinal conditions. Patients with intestinal failure (IF) require long term parenteral nutrition to survive. The only alternative to parenteral nutrition is intestinal transplantation which still entails high mortality. Children with intestinal failure on parenteral nutrition may develop liver failure (LF), as a consequence of central line infections and other conditions. In children with both irreversible IF and LF a combined transplantation is generally considered. Despite low survival rate, combined liver/intestine transplantation is associated to better intestinal graft survival and lower incidence and severity of rejection compared to isolated small bowel transplantation. Recently, isolated liver transplantation was proposed in children with IF and LF. This procedure may have a higher survival probability compared to isolated intestinal transplant, it may allow progressive weaning from PN in children in whom the remnant intestine has the potential for adaptation and offer a timely solution in children for whom intestinal graft is not immediately available. This innovative approach may prove a better option compared to combined transplantation in both the short and long term PMID:19754937

    Purpose To prospectively compare the diagnostic accuracy of intravesical prostatic protrusion (IPP), detrusor wall thickness (DWT), prostate volume (PV) and serum prostate specific antigen (PSA) levels for detecting bladder outlet obstruction (BOO) and predicting acute urinary retention (AUR) secondary to benign prostatic obstruction. Patients and methods In all, 135 men who presented with lower urinary tract symptoms due to benign prostatic enlargement were enrolled in the study; among them, 50 presented with AUR. Thirty normal men in the same age group were included and represented a control group for normative data. Their evaluation included a digital rectal examination, International Prostate Symptom Score and quality-of-life question, uroflowmetry and serum total PSA assay. Transabdominal ultrasonography was used to measure the PV, IPP DWT and post-void residual urine volume. Pressure-flow urodynamic studies were used as the reference standard test for BOO, differentiating obstructed from unobstructed bladders. DWT, IPP, PV and total PSA level served as index tests. To compare the usefulness of the various indices, the area under the curve (AUC) of receiver-operator characteristic curves was calculated for each index. Results According to presentation and urodynamic studies, patients were classified into three groups: Group 1 (no BOO), 50 patients with a BOO index (BOOI) of <40; group 2 (BOO), 35 with a BOOI of >40; and group 3 (AUR), 50 who presented with AUR. The IPP, DWT, PV and PSA levels differed significantly between obstructed and unobstructed patients, with a significant correlation with the BOOI. The AUC for IPP, DWT, PSA and PV were 0.885, 0.783, 0.745 and 0.678, respectively. The IPP threshold at 8 mm provided the best diagnostic accuracy (80%) for detecting BOO, followed by combined DWT and IPP (77.6%). Between patients with and without AUR, there was a highly significant difference in IPP, DWT and PSA; a combined IPP threshold of >8 mm and DWT

    The response of intestinal collagen to obstruction and stress was studied in the rat. Partial small bowel obstructions were created. Preobstruction collagen was measured by injection of tritium labeled proline. New collagen formation after obstruction occurred was followed by injection of carbon-14 labeled proline. At 3 weeks, collagen fractions were identified. Throughout the study, preexisting preobstruction intestinal collagen was metabolically stable with no breakdown or remodeling demonstrable. New collagen formation was rapid and occurred to the largest degree close to the obstruction.

    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.

    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.

    ABSTRACT It is hypothesized that the depletion of microbial members responsible for converting primary bile acids into secondary bile acids reduces resistance to Clostridium difficile colonization. To date, inhibition of C. difficile growth by secondary bile acids has only been shown in vitro. Using targeted bile acid metabolomics, we sought to define the physiologically relevant concentrations of primary and secondary bile acids present in the murine small and large intestinal tracts and how these impact C. difficile dynamics. We treated mice with a variety of antibiotics to create distinct microbial and metabolic (bile acid) environments and directly tested their ability to support or inhibit C. difficile spore germination and outgrowth ex vivo. Susceptibility to C. difficile in the large intestine was observed only after specific broad-spectrum antibiotic treatment (cefoperazone, clindamycin, and vancomycin) and was accompanied by a significant loss of secondary bile acids (deoxycholate, lithocholate, ursodeoxycholate, hyodeoxycholate, and ω-muricholate). These changes were correlated to the loss of specific microbiota community members, the Lachnospiraceae and Ruminococcaceae families. Additionally, physiological concentrations of secondary bile acids present during C. difficile resistance were able to inhibit spore germination and outgrowth in vitro. Interestingly, we observed that C. difficile spore germination and outgrowth were supported constantly in murine small intestinal content regardless of antibiotic perturbation, suggesting that targeting growth of C. difficile will prove most important for future therapeutics and that antibiotic-related changes are organ specific. Understanding how the gut microbiota regulates bile acids throughout the intestine will aid the development of future therapies for C. difficile infection and other metabolically relevant disorders such as obesity and diabetes.

  11. Metabolism of hydroxy fatty acids in dogs with steatorrhea secondary to experimentally produced intestinal blind loops.

    Several aspects of the metabolism of hydroxy fatty acids were studied in dogs with steatorrhea resulting from an experimentally produced jejunal blind loop. In these animals hydroxy acids were present in the stool in amounts far above normal. These acids disappeared from the feces during tetracycline administration and after exclusion of the blind loop-both procedures that corrected the steatorrhea apparently by reducing bacterial overgrowth. Hydroxy acids persisted in higher than normal amounts, however, after administration of taurocholic acid, which also corrected the steatorrhea, but by a different mechanism. Both in normal dogs and in those with blind loops, hydroxy acid constituted a higher percentage of total fatty acids in the jejunum. A possible conclusion is that hydroxy fatty acids have an enterohepatic circulation via the portal system. When hydroxy acids were fed to normal dogs, steatorrhea was not produced and absorption in amounts similar to that of unsubstituted stearic acid was observed. Isotopic oleic and linoleic acids were converted to hydroxy acids both in vivo and during in vitro incubation with feces; stearic acid was not. These findings support the idea that hydroxy acids arise by the addition of water across double bonds, this addition being catalyzed by enzymes of intestinal bacteria. PMID:5725881

    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. PMID:25314845

    PubMed Central

    2014-01-01

    Background Chronic Obstructive Pulmonary Disease (COPD) is a growing worldwide problem that imposes a great burden on the daily life of patients. Since there is no cure, the goal of treating COPD is to maintain or improve quality of life. We have developed a new tool, the Assessment of Burden of COPD (ABC) tool, to assess and visualize the integrated health status of patients with COPD, and to provide patients and healthcare providers with a treatment algorithm. This tool may be used during consultations to monitor the burden of COPD and to adjust treatment if necessary. The aim of the current study is to analyse the effectiveness of the ABC tool compared with usual care on health related quality of life among COPD patients over a period of 18 months. Methods/Design A cluster randomised controlled trial will be conducted in COPD patients in both primary and secondary care throughout the Netherlands. An intervention group, receiving care based on the ABC tool, will be compared with a control group receiving usual care. The primary outcome will be the change in score on a disease-specific-quality-of-life questionnaire, the Saint George Respiratory Questionnaire. Secondary outcomes will be a different questionnaire (the COPD Assessment Test), lung function and number of exacerbations. During the 18 months follow-up, seven measurements will be conducted, including a baseline and final measurement. Patients will receive questionnaires to be completed at home. Additional data, such as number of exacerbations, will be recorded by the patients’ healthcare providers. A total of 360 patients will be recruited by 40 general practitioners and 20 pulmonologists. Additionally, a process evaluation will be performed among patients and healthcare providers. Discussion The new ABC tool complies with the 2014 Global Initiative for Chronic Obstructive Lung Disease guidelines, which describe the necessity to classify patients on both their airway obstruction and a comprehensive

    Intrabiliary rupture is the most frequently seen complication of the hepatic hydatid cysts. Obstructive jaundice can be seen as a complication of the intrabiliary ruptured hepatic hydatid cysts due to the migrated cystic content into bile ducts. In this study, we present two rare complications seen in a patient who has intrabiliary ruptured hepatic hydatid cyst. Obstructive jaundice and secondary gallbladder hydatidosis depending on to the intrabiliary ruptured hepatic hydatid cyst in a 58-year-old man patient were diagnosed and treated. A large choledochal nonfragmanted germinative membran was found in the choledochus as the reason of biliary obstruction. Hepatic hydatid cyst is a world-wide disease. Intrabiliary rupture must be kept in mind in the patients who has hepatic hydatid cyst and biliary tract problems. PMID:25202699

    Obstructive sialadenitis is a common salivary gland disorder usually secondary to viral or bacterial infections, sialolithiasis, duct stricture, or mucous plug. The differential diagnosis also should include dehydration, trauma, and scarring secondary to oral mucosal surgical procedures or neoplasm. It is important to consider neoplasm in these patients, especially when symptoms do not resolve as expected after treatment for obstruction. In a series of 591 cases referred to the Massachusetts General Hospital Oral and Maxillofacial Surgery Service for "obstructive sialadenitis" from 2009 through 2012, 3 patients had obstruction secondary to low-grade follicular lymphoma.

The condition is rare owing to the retroperitoneal fixation of the duodenum, which is sometime absent in cases of intestinal malrotation. We describe the case of a 19-year old man admitted to hospital with abdominal pain and vomiting. A CT scan revealed a duodeno-duodenal intussusception including the head of the pancreas, which was confirmed by laparotomy. The cause was found to be a duodenal membrane with a pinhole passage combined with non-rotation of the duodenum. PMID:26117447

    Duplication of alimentary tract (DAT) presenting as an ileoileal intussusception is a very rare clinical entity. Herein, a case of an ileoileal intussusception due to DAT is presented. A 32-year-old woman was hospitalized due to diffuse, intermittent abdominal pain, vomiting and constipation for 3 d associated with abdominal distention. Plain abdominal X-ray revealed dilated small bowel. Abdominal computed tomography showed grossly dilated small bowel with “sausage” and “doughnut” signs of small bowel intussusception. She underwent laparotomy, with findings of ileoileal intussusception due to a cystic lesion adjacent to the mesenteric side. Resection of the cystic lesion along with the affected segment of intestine, with an end to end anastomosis was performed. The histopathology was consistent with enteric duplication cyst. This case highlights the DAT, although, an uncommon cause of adult ileoileal intussusception should be considered in the differential diagnosis of intussusception in adults, particularly when the leading point is a cystic lesion.

    Introduction Intestinal obstruction following abdominal trauma has previously been described. However, in most reported cases pathological finding was intestinal stenosis. Presentation of the case A 51-year-old male was admitted after a motor vehicle accident. Initial focused abdominal sonogram for trauma and enhanced computerized tomography were normal, however there was a fracture of the tibia. Three days later, he complained of abdominal pain, constipation, and vomiting. An exploratory laparotomy showed bleeding from the omentum and mechanical small bowel obstruction due to a fibrous band. Discussion The patient had prior abdominal surgery, but clinical and radiological findings indicate that the impact of the motor vehicle accident initiated his condition either by causing rotation of a bowel segment around the fibrous band, or by formation of a fibrous band secondary to minimal bleeding from the omentum. Conclusion High index of suspicion of intestinal obstruction is mandatory in trauma patients presenting with complaints of abdominal pain, vomiting, and constipation despite uneventful CT scan.

    Superior mesenteric artery syndrome (SMAS) is an uncommon cause of vomiting and weight loss due to compression of the third part of the duodenum by the superior mesenteric artery. Small bowel adenocarcinoma is an uncommon tumor, which is frequently delayed in diagnosis as its symptoms and signs are non-specific. The present study describes a case of SMAS occurring in a 51-year-old man, caused by intestinal obstruction secondary to a primary adenocarcinoma of the duodenal-jejunal junction. To the best of our knowledge, the present case is the first report of small bowel adenocarcinoma masquerading as SMAS. The present case highlights the importance of considering the possibility of SMAS in patients with upper bowel obstruction caused by intestinal carcinoma. PMID:26998097

    An acute obstruction of blood flow in central vessels of the systemic or pulmonary circulation causes the clinical symptoms of shock accompanied by disturbances of consciousness, centralization, oliguria, hypotension and tachycardia. In the case of an acute pulmonary embolism an intravascular occlusion results in an acute increase of the right ventricular afterload. In the case of a tension pneumothorax, an obstruction of the blood vessels supplying the heart is caused by an increase in extravascular pressure. From a hemodynamic viewpoint circulatory shock caused by obstruction is closely followed by cardiac deterioration; however, etiological and therapeutic options necessitate demarcation of cardiac from non-cardiac obstructive causes. The high dynamics of this potentially life-threatening condition is a hallmark of all types of obstructive shock. This requires an expeditious and purposeful diagnosis and a rapid and well-aimed therapy. PMID:25994928

    This study is the first report of experimental infection and transmission of Menangle virus (MenPV) in pigs. Isolated in 1997 from piglets that were stillborn at a large commercial piggery in New South Wales, Australia, MenPV is a recently identified paramyxovirus of bat origin that causes severe reproductive disease in pigs and an influenza-like illness, with a rash, in humans. Although successfully eradicated from the infected piggery, the virus was only isolated from affected fetuses and stillborn piglets during the period of reproductive disease, and thus the mode of transmission between pigs was not established. To investigate the pathogenesis of MenPV, we undertook time-course studies in 6-week-old pigs following intranasal administration of a low-passage, non-plaque-purified isolate from the lung of an infected stillborn piglet. Viraemia was of short duration and low titre, as determined by real-time RT-PCR and virus isolation. Following an incubation period of 2-3 days, virus was shed in nasal and oral secretions, faeces and urine, typically for less than 1 week. Cessation of shedding correlated with the development of neutralizing antibodies in sera. Secondary lymphoid organs and intestine were identified, using quantitative real-time RT-PCR, as major sites of viral replication and dissemination, and this was confirmed by positive immunolabelling of viral antigen within various lymphoid tissues and intestinal epithelium. These data provide new insights into the pathogenesis of MenPV in weaned pigs, and will facilitate future control and eradication programmes should it ever re-emerge in the pig population.

    Background Gastrointestinal nematode infection is a major challenge to the health and welfare of mammals. Although mammals eventually acquire immunity to nematodes, this breaks down around parturition, which renders periparturient mammals susceptible to re-infection and an infection source for their offspring. Nutrient supplementation reduces the extent of periparturient parasitism, but the underlying mechanisms remain unclear. Here, we use a genome wide approach to assess the effects of protein supplementation on gene expression in the small intestine of periparturient rats following nematode re-infection. Methodology/Principal Findings The use of a rat whole genome expression microarray (Affymetrix Gene 1.0ST) showed significant differential regulation of 91 genes in the small intestine of lactating rats, re-infected with Nippostrongylus brasiliensis compared to controls; affected functions included immune cell trafficking, cell-mediated responses and antigen presentation. Genes with a previously described role in immune response to nematodes, such as mast cell proteases, and intelectin, and others newly associated with nematode expulsion, such as anterior gradient homolog 2 were identified. Protein supplementation resulted in significant differential regulation of 64 genes; affected functions included protein synthesis, cellular function and maintenance. It increased cell metabolism, evident from the high number of non-coding RNA and the increased synthesis of ribosomal proteins. It regulated immune responses, through T-cell activation and proliferation. The up-regulation of transcription factor forkhead box P1 in unsupplemented, parasitised hosts may be indicative of a delayed immune response in these animals. Conclusions/Significance This study provides the first evidence for nutritional regulation of genes related to immunity to nematodes at the site of parasitism, during expulsion. Additionally it reveals genes induced following secondary parasite challenge

    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

    A close relation between different forms of dysganglionosis such as intestinal neuronal dysplasia (IND) type B and aganglionosis has been established. No systematic analysis of other malformations and diseases accompanying IND has been made as yet. Congenital malformations and perinatal morbidity were analyzed in 109 patients with IND seen at the Department of Pediatric Surgery in Mainz from 1977 to 1996. IND was associated with Hirschsprung's disease in 47 cases; 22 children with IND had other abdominal malformations, including anal atresia, rectal stenosis, sigmoidal stenosis, ileal atresia, pyloric stenosis, and esophageal atresia. A cystic bowel duplication, a choledochal cyst, and a persisting urachus were also found. Extra-abdominal malformations such as Down's syndrome, congenital diaphragmatic hernia, aortic stenosis, and malformations of vertebral bodies were seen. Twin siblings of children with IND were either healthy (n=3) or died in utero (n=1). Seventeen children with IND developed severe intra-abdominal complications during the perinatal period such as necrotizing enterocolitis (NEC), meconium ileus, or bowel perforations. NEC was frequently associated with preterm birth. Bowel perforations were seen in mature and preterm newborns with IND. Taken together, IND is found in a variety of obstructive bowel diseases. This may support the hypothesis that IND is a secondary phenomenon or that congenital atresias and stenoses of the digestive tract have a pathogenesis similar to that of intestinal innervation disturbances. IND may also be a part of complex malformation patterns since it occurs with a number of extraintestinal and non-obstructive intestinal malformations. PMID:9716673

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. PMID:27547054

    Forty-one patients were operated upon for acute intestinal obstruction secondary to the presence of phytobezoars, 34 of these patients (83%) having a history of previous gastric surgery for ulcer. The etiologic factor in 44% of cases was oranges and in 56% persimmons (Kakis). Treatment was by enterotomy in 27 patients (65,85%) and by "milking" in 14 (34,15%). Postoperative mortality was 2,44% (1 case). Recurrence was noted in three cases (7,3%) including one with an ileocutaneous fistula, treatment being by enterotomy in 2 cases and "milking" in the third patient. First intention intestinal resection was never required. Five patients required several admissions for subacute obstruction treated conservatively. These findings suggest that gastric surgery predisposes to intestinal obstruction by phytobezoar. Careful exploration of the digestive tube and particularly the stomach should avoid postoperative relapse, while prevention depends on a dietary regimen avoiding excessive intake of foods rich in cellulose, particularly oranges and persimmon fruit.

    Pediatric intestinal motility disorders affect many children and thus not only impose a significant impact on pediatric health care in general but also on the quality of life of the affected patient. Furthermore, some of these conditions might also have implications for adulthood. Pediatric intestinal motility disorders frequently present as chronic constipation in toddler age children. Most of these conditions are functional, meaning that constipation does not have an organic etiology, but in 5% of the cases, an underlying, clearly organic disorder can be identified. Patients with organic causes for intestinal motility disorders usually present in early infancy or even right after birth. The most striking clinical feature of children with severe intestinal motility disorders is the delayed passage of meconium in the newborn period. This sign is highly indicative of the presence of Hirschsprung disease (HD), which is the most frequent congenital disorder of intestinal motility. HD is a rare but important congenital disease and the most significant entity of pediatric intestinal motility disorders. The etiology and pathogenesis of HD have been extensively studied over the last several decades. A defect in neural crest derived cell migration has been proven as an underlying cause of HD, leading to an aganglionic distal end of the gut. Numerous basic science and clinical research related studies have been conducted to better diagnose and treat HD. Resection of the aganglionic bowel remains the gold standard for treatment of HD. Most recent studies show, at least experimentally, the possibility of a stem cell based therapy for HD.

    Background: Ligation of the embryonic gut is an established technique to induce intestinal obstruction and subsequently intestinal atresia in chicken embryos. In this study, we modified this established chicken model of prenatal intestinal obstruction to describe (1) the kinetics of morphological changes, (2) to test if removal of the ligature in ovo is possible in later embryonic development and (3) to describe morphological adaptations following removal of the ligature. Materials and Methods: On embryonic day (ED) 11, small intestines of chick embryos were ligated micro surgically in ovo. In Group 1 (n = 80) gut was harvested proximal and distal to the ligation on ED 12-19. In Group 2 (n = 20) the induced obstruction was released on day 15 and gut was harvested on ED 16-19. Acetyl choline esterase staining was used as to assess resulting morphological changes. Results: A marked intestinal dilatation of the proximal segment can be seen 4 days after the operation (ED 15). The dilatation increased in severity until ED 19 and intestinal atresia could be observed after ED 16. In the dilated proximal segments, signs of disturbed enteric nervous system morphology were obvious. In contrast to this, release of the obstruction on ED 15 in Group 2 resulted in almost normal gut morphology at ED 19. Conclusion: Our model not only allows the description of morphological changes caused by an induced obstruction on ED 11 but also-more important - of morphological signs of adaptation following the release of the obstruction on ED 15.

    Hypertension is a common disease and a crucial predisposing factor of cardiovascular diseases. Approximately 10% of hypertensive patients are secondary hypertension, a pathogenetic factor of which can be identified. Secondary hypertension consists of endocrine, renal, and other diseases. Primary aldosteronism, Cushing's syndrome, pheochromocytoma, hyperthyroidism, and hypothyroidism result in endocrine hypertension. Renal parenchymal hypertension and renovascular hypertension result in renal hypertension. Other diseases such as obstructive sleep apnea syndrome are also very prevalent in secondary hypertension. It is very crucial to find and treat secondary hypertension at earlier stages since most secondary hypertension is curable or can be dramatically improved by specific treatment. One should keep in mind that screening of secondary hypertension should be done at least once in a daily clinical practice. PMID:26619670

    The clinical manifestations of cystic fibrosis (CF) result from dysfunction of the cystic fibrosis transmembrane regulator protein (CFTR). The majority of people with CF have a limited life span as a consequence of CFTR dysfunction in the respiratory tract. However, CFTR dysfunction in the gastrointestinal (GI) tract occurs earlier in ontogeny and is present in all patients, regardless of genotype. The same pathophysiologic triad of obstruction, infection, and inflammation that causes disease in the airways also causes disease in the intestines. This article describes the effects of CFTR dysfunction on the intestinal tissues and the intraluminal environment. Mouse models of CF have greatly advanced our understanding of the GI manifestations of CF, which can be directly applied to understanding CF disease in humans. PMID:23788646

    Human intestinal microbiota create a complex polymicrobial ecology. This is characterised by its high population density, wide diversity and complexity of interaction. Any dysbalance of this complex intestinal microbiome, both qualitative and quantitative, might have serious health consequence for a macro-organism, including small intestinal bacterial overgrowth syndrome (SIBO). SIBO is defined as an increase in the number and/or alteration in the type of bacteria in the upper gastrointestinal tract. There are several endogenous defence mechanisms for preventing bacterial overgrowth: gastric acid secretion, intestinal motility, intact ileo-caecal valve, immunoglobulins within intestinal secretion and bacteriostatic properties of pancreatic and biliary secretion. Aetiology of SIBO is usually complex, associated with disorders of protective antibacterial mechanisms (e.g. achlorhydria, pancreatic exocrine insufficiency, immunodeficiency syndromes), anatomical abnormalities (e.g. small intestinal obstruction, diverticula, fistulae, surgical blind loop, previous ileo-caecal resections) and/or motility disorders (e.g. scleroderma, autonomic neuropathy in diabetes mellitus, post-radiation enteropathy, small intestinal pseudo-obstruction). In some patients more than one factor may be involved. Symptoms related to SIBO are bloating, diarrhoea, malabsorption, weight loss and malnutrition. The gold standard for diagnosing SIBO is still microbial investigation of jejunal aspirates. Non-invasive hydrogen and methane breath tests are most commonly used for the diagnosis of SIBO using glucose or lactulose. Therapy for SIBO must be complex, addressing all causes, symptoms and complications, and fully individualised. It should include treatment of the underlying disease, nutritional support and cyclical gastro-intestinal selective antibiotics. Prognosis is usually serious, determined mostly by the underlying disease that led to SIBO. PMID:20572300

    We investigated small- and large-bowel specimens of three newborn infants presenting with the clinical and radiological symptoms of megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS). Conventional histological staining revealed marked thinning of the longitudinal muscle layer. Electron-microscopic investigations showed typical "central core" vacuolic degeneration of smooth-muscle-cells combined with proliferation of col lagen fibres. The expression of alpha-smooth-muscle actin was absent or markedly reduced in the circular and longitudinal muscle layers and muscularis mucosae compared to the normal controls. These findings suggest that the intestinal obstruction in MMIHS is due to an abnormality of the smooth-muscle cells. PMID:11793054

    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).

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).

    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. PMID:27099450

    A case of intestinal pseudoobstruction occurring 30 yr after radiation therapy is described. Mechanical causes of obstruction were excluded by laparotomy. Histology of full-thickness sections of the small bowel revealed vascular ectasia and sclerosis, serosal fibrosis, neuronal proliferation within the submucosa, and degeneration of the muscle fibers of the circular layer of the muscularis propria. On the basis of the clinical and histologic findings we conclude that, in this patient, intestinal pseudoobstruction was due to muscular and neuronal injury from abdominal irradiation.

    Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a rare cause of intestinal obstruction mainly affecting female neonates. We present a case of a newborn female infant with a history of abdominal distension, bilious vomiting and decreased urine output. Barium enema showed a microcolon. Patient died soon after admission and the autopsy revealed a shortened bowel, a microcolon with abundant ganglion cells in the myenteric plexus, and an enlarged urinary bladder. An interesting finding in this case was the presence of enlarged nerve bundles containing several large ganglion cells on the lateral wall of the cervix. The salient clinical and autopsy findings in this case are presented. PMID:10798164

    Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a rare and the most severe form of functional intestinal obstruction in the newborn. The major features of this congenital and usually lethal anomaly are abdominal distension, bile-stained vomiting, and absent or decreased bowel peristalsis. Abdominal distension is a consequence of the distended, unobstructed urinary bladder with or without upper urinary tract dilation. Most patients with MMIHS are not able to void spontaneously. This article reviews the pathogenesis of MMIHS as well as the clinical, radiological, surgical and histological findings in all reported cases of this syndrome. PMID:15770589

    We report 3 new cases of Mitochondrial-Neuro-Gastro-Intestinal Encephalomyopathy (MNGIE) (or Pseudo-Obstruction-Leukoencephalopathy-Intestinal-Pseudoobstruction Syndrome [POLIP]), a rare disease that associates chronic intestinal pseudo-obstruction (CIPO) and neurological symptoms. A review of the 72 reported cases together with these 3 cases revealed that this condition was associated with (a) a specific cluster of neurological symptoms including leukoencephalopathy (96%), polyneuropathy (96%), ophthalmoplegia (91%) and hearing loss (55%); (b) a CIPO syndrome with the presence of small bowel diverticulae (53%); and (c) mitochondrial cytopathy in 36 of the 37 tested patients (2 of our 3 cases), and thymidine phosphorylase gene mutations in all the 37 tested patients (2 of our cases). The etiology of POLIP/MNGIE syndrome appears therefore to be due to a mitochondrial cytopathy secondary to thymidine phosphorylase gene mutation(s). In 3 cases, including 2 of our 3 patients, mitochondrial abnormalities were evidenced at the ultrastructural level in digestive smooth muscle demonstrating that the pathogenesis of gastrointestinal involvement was directly related to mitochondrial alterations in digestive smooth muscle cells.

    Obstructive sleep apnoea syndrome (OSAS) is a common clinical condition in which the throat narrows or collapses repeatedly during sleep, causing obstructive sleep apnoea events. The syndrome is particularly prevalent in middle-aged and older adults. The mechanism by which the upper airway collapses is not fully understood but is multifactorial and includes obesity, craniofacial changes, alteration in upper airway muscle function, pharyngeal neuropathy and fluid shift towards the neck. The direct consequences of the collapse are intermittent hypoxia and hypercapnia, recurrent arousals and increase in respiratory efforts, leading to secondary sympathetic activation, oxidative stress and systemic inflammation. Excessive daytime sleepiness is a burden for the majority of patients. OSAS is also associated with cardiovascular co-morbidities, including hypertension, arrhythmias, stroke, coronary heart disease, atherosclerosis and overall increased cardiovascular mortality, as well as metabolic dysfunction. Whether treating sleep apnoea can fully reverse its chronic consequences remains to be established in adequately designed studies. Continuous positive airway pressure (CPAP) is the primary treatment modality in patients with severe OSAS, whereas oral appliances are also widely used in mild to moderate forms. Finally, combining different treatment modalities such as CPAP and weight control is beneficial, but need to be evaluated in randomized controlled trials.

    Pathologies acquired after the establishment of an artificial airway include stenosis, granulomas and the formation of pseudomembranes, to name a few. The most common form of presentation in adults is circumferential stenosis, which often requires therapeutic endoscopic measures to achieve resolution. This Case Report describes the case of an obstructive inflammatory tracheal pseudomembrane in the shape of a tracheal septum secondary to repeated intubations that was resolved with conservative treatment. The clinical presentation of this entity generally includes the appearance of respiratory infection and/or atelectasis after the withdrawal of the orotracheal tube as a consequence of the accumulation of secretions between the tracheal wall and the pseudomembrane. Inflammatory pseudomembranes can resolve spontaneously with the help of glucocorticoids, although on occasion they require an invasive endotracheal procedure depending on the evolution.

    2005-01-01

    Patients with short bowel syndrome require long term parenteral nutrition support. However, after massive intestinal resection the intestine undergoes adaptation and nutritional autonomy may be obtained. Given that the complications of parenteral nutrition may be life threatening or result in treatment failure and the need for intestinal transplantation, a more attractive option is to wean patients off nutrition support by optimising the adaptive process. The article examines the evidence that after extensive small bowel resection adaptation occurs in humans and focuses on the factors that influence adaptation and the strategies that have been used to optimise this process. The review is based on an English language Medline search with secondary references obtained from key articles. There is evidence that adaptation occurs in humans. Adaptation is a complex process that results in response to nutrient and non-nutrient stimuli. Successful and reproducible strategies to improve adaptation remain elusive despite an abundance of experimental data. Nevertheless given the low patient survival and quality of life associated with other treatments for irreversible intestinal failure it is imperative that clinical research continues into the optimisation of the adaptation.

    Intestinal transplantation has now emerged as a lifesaving therapeutic option and standard of care for patients with irreversible intestinal failure. Improvement in survival over the years has justified expansion of the indications for intestinal transplantation beyond the original indications approved by Center for Medicare and Medicaid services. Management of patients with intestinal failure is complex and requires a multidisciplinary approach to accurately select candidates who would benefit from rehabilitation versus transplantation. Significant strides have been made in patient and graft survival with several advancements in the perioperative management through timely referral, improved patient selection, refinement in the surgical techniques and better understanding of the immunopathology of intestinal transplantation. The therapeutic efficacy of the procedure is well evident from continuous improvements in functional status, quality of life and cost-effectiveness of the procedure. This current review summarizes various aspects including current practices and evidence based recommendations of intestinal transplantation. PMID:27086894

    Obstructive fibrinous tracheal pseudomembrane (OFTP) is an airway complication that occurs after endotracheal intubation. It originates from superficial mucosal abrasion and desquamation of necrotic tracheal epithelium at the site of cuff pressure. This condition is a rare cause of postextubation stridor. We present a case of postextubation stridor secondary to OFTP, resulting in clinical features of upper airway obstruction > 8 h after extubation. The case features complete obstruction at the tip of the endotracheal tube from OFTP. PMID:24170917

    An obstructed inguinal hernia is a common surgical emergency, which presents with a variety of contents like the small intestine, omentum, and colon. Intestinal knotting is a rare entity encountered in surgical practice; it occurs when one coil of intestine wraps around the other and eventually leads to complications such as intestinal obstruction, ischemia, and gangrene. Both conditions are considered surgical emergencies and should be dealt with through appropriate surgical measures forthwith. We report the case of an obstructed inguinal hernia, which, on exploration, showed an ileoileal knot as its content. Ileoileal knotting is a very rare phenomenon and, to the best of our knowledge, such an ileoileal knot as a content of obstructed inguinal hernia has not been reported in the surgical literature so far.

    Intestinal failure (IF) is a state in which the nutritional demands are not met by the gastrointestinal absorptive surface. A majority of IF cases are associated with short-bowel syndrome, which is a result of malabsorption after significant intestinal resection for numerous reasons, some of which include Crohn's disease, vascular thrombosis, and radiation enteritis. IF can also be caused by obstruction, dysmotility, and congenital defects. Recognition and management of IF can be challenging, given the complex nature of this condition. This review discusses the management of IF with a focus on intestinal rehabilitation, parenteral nutrition, and transplantation. PMID:26974760

    Nonrotation of intestine is a congenital abnormality of the midgut which is due to error in the process of rotation. Errors in the 2nd and 3rd stage of rotation can lead to series of abnormalities in the form of malrotation and reversed rotation. As a consequence, the relative position of other organs likes caecum, intestine, meckel’s diverticulum changes. This can lead to missing diagnosis of common clinical conditions such as appendicitis. The incidence of nonrotation is 1:500. The congenital abnormality appears to be rare as this could be an incidental abnormality. The symptoms of nonrotation of intestine could be biliary vomiting, recurrent abdominal pain. This could be due to midgut volvulus and intestinal obstruction which happens as a consequence of nonrotation of the intestine. The investigations used for detection and confirmation are CT Imaging. Other associations of nonrotation of the intestine are peritoneal bands. Here we report a case of nonrotation of intestines. In the cadaver of age around 70 years, the small intestinal loops was situated in the right side of the abdominal cavity and large intestine looped on the left side of the abdominal cavity. This was also associated with aberrant position of the caecum and appendix. There were associated peritoneal bands extending from the ascending colon to the left side the abdominal wall. The bands had been removed to visualize the large intestinal loops. PMID:24392405

    Bezoars are concretions of foreign materials that impair gastrointestinal motility or cause intestinal obstruction in the stomach, small intestine or bowel of humans or animals. There are many types of them such as phyto, lacto and trichobezoars. Although bezoars are not rare, multiple giant bezoars which totally fill the stomach lumen and have extension to the small intestine (Rapunzel syndrome) are very rare. This is a case report of a young girl who had a history of trichophagia and presented with partial gastric and intestinal obstructive signs. The patient was healthy, and her physical exam was almost normal and the only positive thing in her past medical history was trichophagia from several years ago. She had a big trapped bobble in her stomach and several air-fluid levels in abdominal radiograph and was investigated with endoscopy which confirmed the diagnosis of a huge gastric trichobezoar.

    A wide spectrum of congenital anomalies may cause obstruction in the upper and lower gastrointestinal tract. Neonates with complete upper intestinal obstruction do not usually require further radiological evaluation after radiography. Barium studies are sometimes needed. Barium studies and other comprehensive methods such as ultrasonography, computed tomography and magnetic resonance imaging are usually complementary procedures which are not usually helpful and may even delay surgery, resulting in some complications and death. The decision to perform a given imaging examination should be considered carefully to avoid unnecessary radiation exposure to the patient. The diagnosis of low intestinal obstruction is usually apparent at abdominal radiography because of the presence of many dilated loops. The differentiation between ileal and colonic obstruction can be made with a contrast enema study. Dilute ionic, water-soluble contrast agents and non-balloon tip catheter of appropriate size is preferred for neonatal contrast enemas. Barium sulphate suspensions typically should not be used because of their potential to exacerbate the impaction of meconium plugs in meconium ileus, whereas water-soluble enemas can be therapeutic.

    Death from heroin body packing has been well described in the forensic literature. Most fatalities are due to drug leakage and consequent acute heroin toxicity. Recently, drug traffickers have become more sophisticated in their packaging, and the risk of rupture of drug packets is more remote. Though intestinal obstruction is a recognized risk of body packing, rarely has this resulted in death. We describe four cases of heroin body packing presenting to the Regional Medical Examiner Office in New Jersey. Death in three of these cases was due to intestinal obstruction, with resultant intestinal rupture and peritonitis. Toxicologic evaluation in these three cases was negative for opiates or other drugs of abuse. In one case, death was due to acute heroin toxicity, validated by toxicologic analysis. We briefly discuss the differing drug packaging found in these four cases and the ramifications of packaging as it relates to intestinal obstruction. PMID:10641918

    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. PMID:26440616

    Osteosarcomas are the most frequent primary malignant bone tumors in children and adolescents. Like brain metastases in osteosarcomas, the bowel metastases are very rare. We present the case of a 23-year-old female patient, diagnosed and operated in 2008 of osteosarcoma at the tibia, for which she had sessions of neoadjuvant and adjuvant chemotherapy, but presented lungs metastases for which she underwent surgery in 2014. Then, in March 2015, she was diagnosed with an intracranial expansive process, an osteosarcoma metastasis, for which a total ablation of the tumor was performed during the early postoperatory period, being transferred to the General Surgery Clinic for abdominal pain, abdominal distention, vomiting, and lack of intestinal transit regarding faeces and intestinal gas. Both clinically and imagistically, the diagnosis was of bowel obstruction. This was the reason for performing surgery, thus discovering a bowel obstruction secondary to a metastasis of the terminal ileum and liver metastases that were confirmed as osteosarcoma metastases from an anatomopathological and immunohistochemical point of view. The bowel metastases and the osteosarcoma brain metastases are very rare entities and, their association, most often with young patients, is exceptional. However, bowel metastases must be taken into account as a possible cause of bowel obstruction in patients with osteosarcoma. PMID:27452942

    2015-11-01

    Steroids are fundamental hormones that control a wide variety of physiological processes such as metabolism, immune functions, and sexual characteristics. Historically, steroid synthesis was considered a function restricted to the adrenals and the gonads. In the past 20 years, a significant number of studies have demonstrated that steroids could also be synthesized or metabolized by other organs. According to these studies, the intestine appears to be a major source of de novo produced glucocorticoids as well as a tissue capable of producing and metabolizing sex steroids. This finding is based on the detection of steroidogenic enzyme expression as well as the presence of bioactive steroids in both the rodent and human gut. Within the intestinal mucosa, the intestinal epithelial cell layer is one of the main cellular sources of steroids. Glucocorticoid synthesis regulation in the intestinal epithelial cells is unique in that it does not involve the classical positive regulator steroidogenic factor-1 (SF-1) but a closely related homolog, namely the liver receptor homolog-1 (LRH-1). This local production of immunoregulatory glucocorticoids contributes to intestinal homeostasis and has been linked to pathophysiology of inflammatory bowel diseases. Intestinal epithelial cells also possess the ability to metabolize sex steroids, notably estrogen; this mechanism may impact colorectal cancer development. In this review, we contextualize and discuss what is known about intestinal steroidogenesis and regulation as well as the key role these functions play both in physiological and pathological conditions.

    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

    Maldigestion due to exocrine pancreatic insufficiency leads to intestinal malabsorption and consequent malnutrition, a mechanism proposed to cause growth retardation associated with cystic fibrosis (CF). However, although enzyme replacement therapy combined with increased caloric intake improves weight gain, the effect on stature is not significant, suggesting that growth retardation has a more complex etiology. Mouse models of CF support this, since these animals do not experience exocrine pancreatic insufficiency yet are growth impaired. Cftr absence from the intestinal epithelium has been suggested as a primary source of growth retardation in CF mice, a concept we directly tested by generating mouse models with Cftr selectively inactivated or restored in intestinal epithelium. The relationship between growth and functional characteristics of the intestines, including transepithelial electrophysiology, incidence of intestinal obstruction, and histopathology, were assessed. Absence of Cftr exclusively from intestinal epithelium resulted in loss of cAMP-stimulated short-circuit current, goblet cell hyperplasia, and occurrence of intestinal obstructions but only slight and transient impaired growth. In contrast, specifically restoring Cftr to the intestinal epithelium resulted in restoration of ion transport and completely protected against obstruction and histopathological anomalies, but growth was indistinguishable from CF mice. These results indicate that absence of Cftr in the intestinal epithelium is an important contributor to the intestinal obstruction phenotype in CF but does not correlate with the observed growth reduction in CF.

    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

  11. Age-dependent Requirement for γδ T Cells in the Primary but Not Secondary Protective Immune Response against an Intestinal Parasite

    Between weaning (3 wk of age) and adulthood (7 wk of age), mice develop increased resistance to infection with Eimeria vermiformis, an abundant intestinal parasite that causes coccidiosis. This development of resistance was perturbed in T cell receptor (TCR)δ−/− mice, which at 4 wk of age remained largely susceptible to infection and prone to infection-associated dehydration. These phenotypes were rescued by the repopulation of γδ cells after adoptive transfer of lymphoid progenitors into newborn recipients. Because αβ T cells are necessary and sufficient for the protection of adult mice against E. vermiformis, the requirement for γδ cells in young mice shows a qualitative difference between the cellular immune responses operating at different ages. An important contribution toward primary immune protection in young hosts may have provided a strong selective pressure for the evolutionary conservation of γδ cells. This notwithstanding, the development of effective, pathogen-specific immunity in young mice requires αβ T cells, just as it does in adult mice. PMID:14597739

    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

    Obstructive sleep apnea (OSA) is independently associated with death from cardiovascular diseases, including myocardial infarction and stroke. Myocardial infarction and stroke are complications of atherosclerosis; therefore, over the last decade investigators have tried to unravel relationships between OSA and atherosclerosis. OSA may accelerate atherosclerosis by exacerbating key atherogenic risk factors. For instance, OSA is a recognized secondary cause of hypertension and may contribute to insulin resistance, diabetes, and dyslipidemia. In addition, clinical data and experimental evidence in animal models suggest that OSA can have direct proatherogenic effects inducing systemic inflammation, oxidative stress, vascular smooth cell activation, increased adhesion molecule expression, monocyte/lymphocyte activation, increased lipid loading in macrophages, lipid peroxidation, and endothelial dysfunction. Several cross-sectional studies have shown consistently that OSA is independently associated with surrogate markers of premature atherosclerosis, most of them in the carotid bed. Moreover, OSA treatment with continuous positive airway pressure may attenuate carotid atherosclerosis, as has been shown in a randomized clinical trial. This review provides an update on the role of OSA in atherogenesis and highlights future perspectives in this important research area. PMID:21813534

    Significant advances have been made recently in elucidating the cellular consequences of urinary tract obstruction during renal development. Urinary tract obstruction impairs growth and maturation of the kidney, and can also cause renal maldevelopment. This includes a reduction in the number of nephrons, tubular atrophy, and progressive interstitial fibrosis. Apoptosis (programmed cell death) accounts for much of the loss of tubular epithelial cells. Factors contributing to apoptosis include stretching of cells in dilated tubules, altered renal production of growth factors, and infiltration of the renal interstitium by macrophages. Two major controversies remain regarding the surgical management of congenital obstructive nephropathy: first, which fetuses with bladder outlet obstruction should undergo prenatal intervention, and second, which infants should undergo early pyeloplasty for ureteropelvic junction obstruction? Even after successful surgery for congential obstructive nephropathy, all patients should be followed for hypertension, proteinuria, or renal deterioration. PMID:15200251

    The non-specific symptoms the patients express upon the presentation of female bladder outlet obstruction make it a challenge to diagnose. There are subtle differences between the obstructed patient and those whose bladders are underactive and/or fail to mount a detrusor contraction. These disparities can be extracted through a thorough history and examination. At times, the clinician may utilize nomograms, non-invasive uroflow, and urodynamics with the addition of fluoroscopy to establish the diagnosis of obstruction. Management of the obstruction depends on the nature of the condition, whether functional or anatomical. The increase in the number of sling procedures performed to treat stress urinary incontinence has resulted in a rise in the number of iatrogenic obstructions. The temporal relationship between surgery and obstruction is the key to identifying the problem. PMID:26902625

    A four-day-old boy presented with persistent bilious vomiting, bloody stained stool, and mild abdominal distension. Transabdominal ultrasound demonstrated a round soft-tissue mass-like structure in the right upper quadrant. With color Doppler ultrasound, the whirlpool sign was observed. Abdominal radiograph showed nonspecific findings. Upper gastrointestinal series revealed upper gastrointestinal tract obstruction at the level of distal duodenum. The diagnosis of intestinal malrotation with midgut volvulus was established and the treated surgically. Intestinal malrotation is congenital abnormal positioning of the bowel loops within the peritoneal cavity resulting in abnormal shortening of mesenteric root that is predisposed to midgut volvulus. Neonates and infants with persistent bilious vomiting should undergo diagnostic workup and preferably ultrasound as the first step. With classic sonographic appearance of whirlpool sign, even further imaging investigations is often not needed, and the surgeon should be alerted to plan surgery. PMID:27594965

    Diospyrobezoars are a rare cause of small intestinal obstruction. A 78-year-old man, with a history of persimmons ingestion and gastrectomy, presented with upper abdominal pain and weight loss. The upper gastrointestinal endoscopy showed a huge bezoar in the stomach. After initial endoscopic fragmentation, the abdominal X-ray revealed intestinal obstruction and the colonoscopy showed large fragments of the bezoar filling the terminal ileum. The migrated bezoar pieces were successfully removed by endoscopic fragmentation with a cutting lithotripter. PMID:25100813

    PRUPOSE Bacterial translocation has been shown to occur in critically ill patients after extensive trauma, shock, sepsis, or thermal injury. The present study investigates mesenteric microcirculatory dysfunctions, the bacterial translocation phenomenon, and hemodynamic/metabolic disturbances in a rat model of intestinal obstruction and ischemia. METHODS Anesthetized (pentobarbital 50 mg/kg, i.p.) male Wistar rats (250–350 g) were submitted to intestinal obstruction or laparotomy without intestinal obstruction (Sham) and were evaluated 24 hours later. Bacterial translocation was assessed by bacterial culture of the mesenteric lymph nodes (MLN), liver, spleen, and blood. Leukocyte-endothelial interactions in the mesenteric microcirculation were assessed by intravital microscopy, and P-selectin and intercellular adhesion molecule (ICAM)-1 expressions were quantified by immunohistochemistry. Hematocrit, blood gases, lactate, glucose, white blood cells, serum urea, creatinine, bilirubin, and hepatic enzymes were measured. RESULTS About 86% of intestinal obstruction rats presented positive cultures for E. coli in samples of the mesenteric lymph nodes, liver, and spleen, and 57% had positive hemocultures. In comparison to the Sham rats, intestinal obstruction induced neutrophilia and increased the number of rolling (~2-fold), adherent (~5-fold), and migrated leukocytes (~11-fold); this increase was accompanied by an increased expression of P-selectin (~2-fold) and intercellular adhesion molecule-1 (~2-fold) in the mesenteric microcirculation. Intestinal obstruction rats exhibited decreased PaCO2, alkalosis, hyperlactatemia, and hyperglycemia, and increased blood potassium, hepatic enzyme activity, serum urea, creatinine, and bilirubin. A high mortality rate was observed after intestinal obstruction (83% at 72 h vs. 0% in Sham rats). CONCLUSION Intestinal obstruction and ischemia in rats is a relevant model for the in vivo study of mesenteric microcirculatory dysfunction

    Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a rare and frequently lethal form of severe functional intestinal obstruction more commonly found in girls. Imaging features characteristic of this disease include a large dilated bladder, microcolon and intestinal dysmotility. Additional imaging findings may include intestinal malrotation, hydronephrosis and vesicoureteral reflux. It is usually fatal in the first year of life. Because presenting clinical and imaging features can mimic other causes of neonatal bowel obstruction, we compiled examples of this disorder to help the pediatric radiologist recognize imaging findings associated with MMIHS and aid in the development of a long-term management plan and in counseling the family regarding implications of this disorder. We reviewed recent and historical literature relevant to MMIHS and present the imaging and clinical features of four patients with MMIHS treated at our institution as examples of this uncommon disorder.

    Duplications of the alimentary tract are congenital malformations. The ileum is the most commonly affected organ. A lot of duplications are incidentally diagnosed but most of patients present a combination of pain or complications such as obstructive symptoms, intestinal intussusception, perforation or volvulus. We report the case of a 6-years-old girl, with intermittent abdominal pain and vomits for two months long. Laboratory work was completely normal and in the radiology analysis (abdominal sonography and magnetic resonance) a cystic image with intestinal volvulus was observed. The patient underwent laparotomy, Ladd's procedure was done and the cyst was resected. In conclusion, if a patient is admitted with abdominal pain and obstructive symptoms, it is important to consider duplication of the alimentary tract as a possible diagnosis. PMID:26065113

    Background: Congenital duodenal obstruction is one of the commonest causes of neonatal intestinal obstruction. We are presenting our 15-year experience by analyzing clinical spectrum and outcome in neonates with duodenal obstruction admitted at our center. Material and Methods: The hospital records of all neonates admitted with duodenal obstruction from June 2000 to June 2015 were reviewed. The patient records were analyzed for antenatal diagnosis, age, sex, clinical presentation, diagnosis, associated anomalies, surgical procedures performed; postoperative morbidity and mortality. We excluded from our study malrotation of gut associated with congenital diaphragmatic hernia and abdominal wall defects. Results: A total of 81 patients were admitted, out of which 56 were males and 25 were females. Polyhydramnios was detected in 24 (30%) pregnancies. Average birth weight was 2.1±1.0Kg and average gestational age was 38 (SD±1) weeks with 17 (21%) preterm neonates. Presenting features were vomiting in 81(100%) which was bilious in 81% and non-bilious in 19%, epigastric fullness in 56 (69%) and dehydration in 18 (22%) and failure to thrive in 16 (19%). Most common cause of obstruction was duodenal atresia in 38 (46.9%), followed by malrotation of gut in 33 (40.7%), and annular pancreas in 4 cases. Depending upon site of location, infra-ampullary obstruction was the most common in 64 (79%), supra-ampullary in 9 (7.4%) and ampullary 8 neonates. Both duodenal atresia and malrotation of gut was present in 4 cases. X-ray abdomen was most commonly used investigation to confirm the diagnosis. All cases were managed surgically by open laparotomy. Eleven (13.5%) patients died due to sepsis and associated congenital anomalies. Conclusion: Congenital duodenal obstruction most commonly presents in early neonatal period with features of upper GIT obstruction like vomiting and epigastrium fullness as in our series.

    Introduction. The aim of the study was to evaluate our children who are operated on for anomalous congenital band while increasing the awareness of this rare reason of intestinal obstruction in children which causes a diagnostic challenge. Patients and Methods. We retrospectively reviewed the records of fourteen children treated surgically for intestinal obstructions caused by anomalous congenital bands. Results. The bands were located between the following regions: the ascending colon and the mesentery of the terminal ileum in 4 patients, the jejunum and mesentery of the terminal ileum in 3 patients, the ileum and mesentery of the terminal ileum in 2 patients, the ligament of Treitz and mesentery of the jejunum in one patient, the ligament of Treitz and mesentery of the terminal ileum in one patient, duodenum and duodenum in one patient, the ileum and mesentery of the ileum in one patient, the jejunum and mesentery of the jejunum in one patient, and Meckel's diverticulum and its ileal mesentery in one patient. Band excision was adequate in all of the patients except the two who received resection anastomosis for intestinal necrosis. Conclusion. Although congenital anomalous bands are rare, they should be considered in the differential diagnosis of patients with an intestinal obstruction. PMID:27478432

    Small bowel obstruction is rarely caused by bezoars. An important cause of phytobezoars are dried fruits. A 56 year old man presented to our department with symptoms of acute intestinal obstruction. Abdomen was distended and tender at the right and left lower quadrants. Bowel movements were decreased, and rectum was empty on digital examination. Upright plain films of the abdomen revealed multiple air-fluid levels and patient was immediately operated on. Due to the ischaemia of short small bowel segment, resection and end to end anastomosis were performed. After resection, bowel was opened and an apricot was found in the small bowel lumen. Although the dried apricot was small enough to pass through the pylorus spontaneously, it became swollen in fluid and started to obstruct the small bowel lumen especially in the terminal ileum. Obstruction by undigested food is rare and mostly seen in children, edentulous older people and patients with mental disorders. In conclusion, dried fruits, when swallowed without chewing, may cause intestinal obstruction. PMID:22125996

    Introduction Intestinal atresia accounts for approximately one third of all cases of neonatal intestinal obstruction. There is controversy regarding pathogenesis of congenital atresia and stenosis of small bowel. Studies regarding clinical manifestations and specific histopathological features of neonatal intestinal atresia are scarce in Indian literature. Aim To understand the histomorphological features and thus suggest pathophysiology of cases with Intestinal Atresia. Materials and Methods Out of 147 cases, of intestinal obstruction in newborn studied over a period of 5 years, 39 cases of intestinal atresia were found. Their histomorphological details with clinical manifestations were studied. Results Type II was the commonest type of atresia. Associated anomalies noted were gastroschisis, volvulus, anal stenosis, microcolon, annular pancreas, meconium cyst and duplication cyst. Histological changes observed were ulceration, flattening, abnormal villous configuration, luminal obliteration, narrowing, haemangiomatous proliferation of blood vessels, fibrosis, haemorrhage, calcification, and mesenchymal condensation around the blood vessels. Gangrene and perforation has also noted in some cases. Conclusion An intrauterine intestinal ischemia due to vascular pathology followed by resorption of the bowel is the possible explanation for the development of intestinal atresia. PMID:26674207

    Endometriosis is a chronic, benign gynaecological disorder that is frequent in women of a child-bearing age. It is estimated that there is some degree of endometriosis in as many as 15% of pre-menopausal women, associated with a history of infertility, caesarean antecedents, dysmenorrhoea and abnormality in uterine bleeding. It is believed to be due to the rise of menstrual contents through the Fallopian tubes (retrograde menstruation). In the intestinal affectation, the colon is the segment most frequently affected, above all at the rectosigmoidal level. The clinical features are unspecific, with abdominal pain the most frequent and/or pelvic pain of a cholic type that coincides with, or is exacerbated by, menstruation. Differential diagnosis includes intestinal inflammatory disease, diverticulitis, ischemic colitis and neoplastic processes, with the definitive diagnosis being anatomopathological. With respect to treatment, this will depend on the clinical features and the age of the patient, as well as her wishes with regard to pregnancy. PMID:18953367

    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, respectively. 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 cmH2O 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. PMID:21632056

    Airflow obstruction has been defined using spirometric test results when the forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) ratio is below a fixed cutoff (<70%) or lower limits of normal (LLN) from reference equations that are based on values from a normal population. However, similar to other positive or abnormal diagnostic test results that are used to identify the presence of disease, perhaps airflow obstruction should be defined based on the values of FEV1/FVC for a population of individuals with known disease such as chronic obstructive pulmonary disease (COPD). Unfortunately, we do not know such a distribution of values of FEV1/FVC for patients with COPD since there is no gold standard for this syndrome or condition. Yet, we have used this physiologic definition of airflow obstruction based on a normal population to identify patients with COPD. In addition, we have defined airflow obstruction as either being present or absent. Instead, we should use a different approach to define airflow obstruction based on the probability or likelihood that the airflow obstruction is present which in turn would give us the probability or likelihood of a disease state such as COPD.

    Partial intestinal obstruction causes smooth muscle hypertrophy, enteric neuronal plasticity, motility disorders, and biomechanical remodeling. In this study we characterized the stimulus-response function of afferent fibers innervating the partially obstructed jejunum. A key question is whether changes in afferent firing arise from remodeled mechanical tissue properties or from adaptive afferent processes. Partial obstruction was created by placing a polyethylene ring for 2 wk in jejunum of seven rats. Sham obstruction was made in six rats and seven rats served as normal controls. Firing from mesenteric afferent nerve bundles was recorded during mechanical ramp, relaxation, and creep tests. Stress-strain, spike rate increase ratio (SRIR), and firing rate in single units were assessed for evaluation of interdependency of the mechanical stimulations, histomorphometry data, and afferent nerve discharge. Partial intestinal obstruction resulted in hypertrophy and jejunal stiffening proximal to the obstruction site. Low SRIR at low strains during fast distension and at high stresses during slow distension was found in the obstructed rats. Single unit analysis showed increased proportion of mechanosensitive units but absent high-threshold (HT) units during slow stimulation, decreased number of HT units during fast stimulation, and shift from HT sensitivity towards low threshold sensitivity in the obstructed jejunum. Biomechanical remodeling and altered afferent response to mechanical stimulations were found in the obstructed jejunum. Afferents from obstructed jejunum preserved their function in encoding ongoing mechanical stimulation but showed changes in their responsiveness. The findings support that mechanical factors rather than adaption are important for afferent remodeling. PMID:26585414

    Intestinal failure (IF) is a state in which the nutritional demands of the body are not met by the gastrointestinal absorptive surface. It is a long-recognized complication associated with short bowel syndrome, which results in malabsorption after significant resection of the intestine for many reasons or functional dysmotility. Etiologies have included Crohn's disease, vascular complications, and the effects of radiation enteritis, as well as the effects of intestinal obstruction, dysmotility, or congenital defects. While IF has been long-recognized, it has historically not been uniformly defined, which has made both recognition and management challenging. This review examines the previous definitions of IF as well as the newer definition and classification of IF and how it is essential to IF clinical guidelines. PMID:27447791

    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.

    This article reports on the clinical practice guidelines developed by a multidisciplinary group working on the indications and uses of the various available treatment options for relieving intestinal obstruction or its symptoms in patients with peritoneal carcinomatosis. These guidelines are based on a literature review and expert opinion. The recommended strategy involves a clinical and radiological evaluation, of which CT of the abdomen is a crucial component. The results, together with an analysis of the prognostic criteria, are used to determine whether surgery or stenting is the best option. In most patients, however, neither option is feasible, and the main emphasis, therefore, is on the role and administration of various symptomatic medications such as glucocorticoids, antiemetic agents, analgesics, and antisecretory agents (anticholinergic drugs, somatostatin analogues, and proton-pump inhibitors). Nasogastric tube feeding is no longer used routinely and should instead be discussed on a case-by-case basis. Recent studies have confirmed the efficacy of somatostatin analogues in relieving obstruction-related symptoms such as nausea, vomiting, and pain. However, the absence of a marketing license and the high cost of these drugs limit their use as the first-line treatment, except in highly selected patients (early recurrence). When these medications fail to alleviate the symptoms of obstruction, venting gastrostomy should be considered promptly. Rehydration is needed for virtually every patient. Parenteral nutrition and pain management should be adjusted according to the patient needs and guidelines. PMID:24798105

    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

    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.

    Pediatric intestinal failure (IF) remains to be associated with significant morbidity and mortality, the most frequent underlying etiologies being short bowel syndrome (SBS), and primary motility disorders. Management aims to assure growth and development, while preventing complications and facilitating weaning off parenteral support (PS) by fully utilizing adaptation potential of the remaining gut. Probability of survival and weaning off PS is improved by coordinated multidisciplinary intestinal rehabilitation combining individualized physiological enteral and parenteral nutrition (PN), meticulous central line care and medical management with carefully planned surgical care. Increasing evidence suggests that autologous intestinal reconstruction (AIR) surgery is effective treatment for selected short bowel patients. Bowel lengthening procedures normalize pathological adaptation-associated short bowel dilatation with potential to support intestinal absorption and liver function by various mechanisms. Although reversed small intestinal segment, designed to prolong accelerated intestinal transit, improves absorption in adult SBS, its feasibility in children remains unclear. Controlled bowel obstruction to induce dilatation followed by bowel lengthening aims to gain extra length in patients with the shortest duodenojejunal remnant. Reduced PS requirement limits the extent of complications, improving prognosis and quality of life. The great majority of children with SBS can be weaned from PS while prognosis of intractable primary motility disorders remains poor without intestinal transplantation, which serves as a salvage therapy for life-threatening complications such as liver failure, central vein thrombosis or recurrent bloodstream infections.

    The mucinous cystadenoma, a common benign neoplasm of the ovary, may sometime bring about a fatal outcome known as pseudomyxoma peritonei which is characterized by massive accumulation of mucinous substance in the peritoneal cavity, resulting in extensive adhesions, chronic progressive intestinal obstruction and finally death of the patient. Surgical approach to this condition proves to be a palliative procedure. Repeated operation can only remove part of the geletinous material and reaccumulation of mucus within 1-2 years after the initial surgery is almost a rule. In view of the benign histologic nature of the disease, chemotherapy, either systemic or intraperitoneal, and radiotherapy are generally ineffective in arresting the progression of the pathologic process and preventing the reaccumulation of mucus. Therefore, the only hope lies on the introduction into the peritoneal cavity some agents which may dissolve the accumulated mucin, relieve the intestinal obstruction, and consequently, prolong and even save the life f the patient. Based on this conception, sporadic articles by a few authors(1,2)ap-peared in the literature reporting their clinical experience with different mucolytic agents. However, some blindness would inevitably be involved in such investigations due to the lack of a comprehensive understanding of the chemical structures of the substance. The purpose of the present paper is to report our preliminary results of study of the secondary structures of mucin secreted by this special type of tumor.

    Eighteen patients were examined; they were suffering from small bowel obstruction due to adhesions (7 cases), hernia (3 cases), carcinoma (2 cases), metastasis from melanoma (1 case), radiation enteritis (2 cases), intramural hematoma (2 cases), and peritoneal carcinosis (1 case). CT capabilities in showing the site and the cause of obstruction were evaluated. CT was performed after conventional radiology in 13 cases, while in 5 cases it was the first exam and demonstrated the condition as an occasional finding. In all cases i.v. contrast agents were administered. Filling of the intestinal loop by oral contrast agent was never performed since the hypodense fluid present in the distended intestinal loops allowed good evaluation of intestinal walls. CT always showed the level of the obstruction thanks to the presence of the distended loops (phi: 4-8 cm) above the condition and of collapsed loops below. In 8/18 cases (44%) it was possible to show the cause of the obstruction. Those due to neoplasms, herniae and intramural hematomas were correctly diagnosed. On the contrary, it was not possible to identify the cause of the obstructions due to adhesions, radiation enteritis and peritoneal metastases because of the absence, in such cases, of specific parietal alterations. According to our results, CT is suitable in patients suffering from small bowel obstruction because it allows: to always show the site of the obstruction and, in some cases, its cause; to diagnose closed loop obstructions; to obtain a simultaneous staging in neoplastic patients.

    Obstructive sleep apnea is a common sleep disorder associated with several medical conditions, increased risk of motor vehicle accidents, and overall healthcare expenditure. There is higher prevalence of depression in people with obstructive sleep apnea in both clinical and community samples. Many symptoms of depression and obstructive sleep apnea overlap causing under-diagnosis of obstructive sleep apnea in depressed patients. Sleep problems, including obstructive sleep apnea, are rarely assessed on a regular basis in patients with depressive disorders, but they may be responsible for antidepressant treatment failure. The mechanism of the relationship between obstructive sleep apnea and depression is complex and remains unclear. Though some studies suggest a mutual relationship, the relationship remains unclear. Several possible pathophysiological mechanisms could explain how obstructive sleep apnea can cause or worsen depression. Increased knowledge of the relationship between obstructive sleep apnea and depression might significantly improve diagnostic accuracy as well as treatment outcomes for both obstructive sleep apnea and depression.

    The records of all patients undergoing hepatobiliary imaging with technetion radioisotopes at our hospital from January 1980 to March 1983 were reviewed and 29 scans met the criteria for a pattern consistent with complete biliary tract obstruction. Biliary tract obstruction (due to choledocholithiasis, primary or secondary carcinoma involving the common bile duct, and pancreatitis) was documented in 24 of these patients. However, the remaining five patients had a patent common bile duct, and the etiologic factor was intrahepatic cholestasis secondary to sepsis in four and peritonitis in one. A classification of altered biliary dynamics in hepatobiliary imaging, which is based on the classification of jaundice, is proposed.

    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

    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.

    Chronic obstructive pulmonary disease (COPD) is a common disease with high global morbidity and mortality. COPD is characterized by poorly reversible airway obstruction, which is confirmed by spirometry, and includes obstruction of the small airways (chronic obstructive bronchiolitis) and emphysema, which lead to air trapping and shortness of breath in response to physical exertion. The most common risk factor for the development of COPD is cigarette smoking, but other environmental factors, such as exposure to indoor air pollutants - especially in developing countries - might influence COPD risk. Not all smokers develop COPD and the reasons for disease susceptibility in these individuals have not been fully elucidated. Although the mechanisms underlying COPD remain poorly understood, the disease is associated with chronic inflammation that is usually corticosteroid resistant. In addition, COPD involves accelerated ageing of the lungs and an abnormal repair mechanism that might be driven by oxidative stress. Acute exacerbations, which are mainly triggered by viral or bacterial infections, are important as they are linked to a poor prognosis. The mainstay of the management of stable disease is the use of inhaled long-acting bronchodilators, whereas corticosteroids are beneficial primarily in patients who have coexisting features of asthma, such as eosinophilic inflammation and more reversibility of airway obstruction. Apart from smoking cessation, no treatments reduce disease progression. More research is needed to better understand disease mechanisms and to develop new treatments that reduce disease activity and progression. PMID:27189863

    Phytobezoar, a concretion of indigestible fibers derived from ingested vegetables and fruits, is the most common type of bezoar. Diospyrobezoar is a subtype of phytobezoar formed after excessive intake of persimmons (Diospyros kaki). We report the case of a diabetic man with a 5-day history of abdominal pain after massive ingestion of persimmons who developed signs of complicated small bowel obstruction. The patient had a previous history of Billroth II hemigastrectomy associated with truncal vagotomy to treat a chronic duodenal ulcer 14 years earlier. Since intestinal obstruction was suspected, he underwent emergency laparotomy that revealed an ileal obstruction with small bowel perforation and local peritonitis due to a phytobezoar that was impacted 15 cm above the ileocecal valve. After segmental intestinal resection, the patient had a good recovery and was discharged on the 6th postoperative day. This report provides evidence that diospyrobezoar should be considered as a possible cause of small bowel obstruction in patients who have previously undergone gastric surgery. PMID:23271989

    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.

    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.

    This is a complex condition, recognized primarily in brachycephalic breeds, that results in varying degrees of upper airway obstruction. The signs consist of respiratory distress, stridor, reduced exercise tolerance, and in more severe cases, cyanosis and collapse. The inherent anatomy of the brachycephalic skull contributes to the development of these signs. Such anatomic features include: a shortened and distorted nasopharynx, stenotic nares, an elongated soft palate, and everted laryngeal saccules. The increased negative pressure created in the pharyngolaryngeal region, as a result of these obstructing structures, ultimately results in distortion and collapse of the arytenoid cartilages of the larynx.

    BACKGROUND: There is significant variation between physicians in terms of how they perform therapeutic bronchoscopy, but there are few data on whether these differences impact effectiveness. METHODS: This was a multicenter registry study of patients undergoing therapeutic bronchoscopy for malignant central airway obstruction. The primary outcome was technical success, defined as reopening the airway lumen to > 50% of normal. Secondary outcomes were dyspnea as measured by the Borg score and health-related quality of life (HRQOL) as measured by the SF-6D. RESULTS: Fifteen centers performed 1,115 procedures on 947 patients. Technical success was achieved in 93% of procedures. Center success rates ranged from 90% to 98% (P = .02). Endobronchial obstruction and stent placement were associated with success, whereas American Society of Anesthesiology (ASA) score > 3, renal failure, primary lung cancer, left mainstem disease, and tracheoesophageal fistula were associated with failure. Clinically significant improvements in dyspnea occurred in 90 of 187 patients measured (48%). Greater baseline dyspnea was associated with greater improvements in dyspnea, whereas smoking, having multiple cancers, and lobar obstruction were associated with smaller improvements. Clinically significant improvements in HRQOL occurred in 76 of 183 patients measured (42%). Greater baseline dyspnea was associated with greater improvements in HRQOL, and lobar obstruction was associated with smaller improvements. CONCLUSIONS: Technical success rates were high overall, with the highest success rates associated with stent placement and endobronchial obstruction. Therapeutic bronchoscopy should not be withheld from patients based solely on an assessment of risk, since patients with the most dyspnea and lowest functional status benefitted the most.

    Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS), a visceral myopathy causing intestinal obstruction in the newborn, is a generally fatal condition, with death being secondary either to sepsis or to malnutrition if long-term intravenous feeding is not provided. A patient with MMIHS is described who has been raised by total parenteral nutrition (TPN) for seven years since her birth. Severe hepatic dysfunction was encountered in early infancy, which gradually cleared after the initiation of milk feeding by mouth, although the milk could not be absorbed because of the high-output jejunostomy. The patient also experienced a bone disease similar to scurvy but caused by copper deficiency at the age of 9 months. The central venous catheter now in situ is the 25th one for the patient. When these catheters were evaluated, the Broviac proved more efficacious than the traditional Silastic for use in long-term TPN. The patient does not yet have normal bowel function and still requires TPN. PMID:2520338

    Partial obstruction of the murine ileum led to changes in the gross morphology and ultrastructure of the tunica muscularis. Populations of interstitial cells of Cajal (ICC) decreased oral, but not aboral, to the site of obstruction. Since ICC generate and propagate electrical slow waves in gastrointestinal muscles, we investigated whether the loss of ICC leads to loss of function in partial bowel obstruction. Changes in ICC networks and electrical activity were monitored in the obstructed murine intestine using immunohistochemistry, electron microscopy and intracellular electrophysiological techniques. Two weeks following the onset of a partial obstruction, the bowel increased in diameter and hypertrophy of the tunica muscularis was observed oral to the obstruction site. ICC networks were disrupted oral to the obstruction, and this disruption was accompanied by the loss of electrical slow waves and responses to enteric nerve stimulation. These defects were not observed aboral to the obstruction. Ultrastructural analysis revealed no evidence of cell death in regions where the lesion in ICC networks was developing. Cells with a morphology intermediate between smooth muscle cells and fibroblasts were found in locations that are typically populated by ICC. These cells may have been the redifferentiated remnants of ICC networks. Removal of the obstruction led to the redevelopment of ICC networks and recovery of slow wave activity within 30 days. Neural responses were partially restored in 30 days. These data describe the plasticity of ICC networks in response to partial obstruction. After obstruction the ICC phenotype was lost, but these cells regenerated when the obstruction was removed. This model may be an important tool for evaluating the cellular/molecular factors responsible for the regulation and maintenance of the ICC phenotype. PMID:11600689

    This review presents the rationale and supporting data for a recent paradigm shift in our understanding of meibomian gland dysfunction (MGD). The historical understanding of MGD has been that of an infectious hypersecretory disorder with obvious signs of inflammation, hypersecretion, and purulent excreta. The current understanding of MGD now includes the polar concept of a less obvious or nonobvious type of hyposecretory obstructive MGD, where inflammation and other signs of pathology may be absent unless special examination techniques are employed. A new term, nonobvious obstructive MGD (NOMGD), is used to describe what may be the most common form of obstructive MGD. Obstructive MGD is an area of growing importance because obstructive MGD is now recognized to be the most common cause of evaporative dry eye, and because NOMGD seems to be the precursor to obvious obstructive MGD, it is also an important area to understand. The prevalence of NOMGD seems to be very high but currently significantly underdiagnosed. This review presents the relevant anatomy and physiology, concepts of obstructive MGD, the usual absence of inflammation in obstructive MGD, nomenclature and classification of obstructive and NOMGD, clinical diagnosis of NOMGD emphasizing the necessity for diagnostic expression, the use of a new instrument for diagnostic expression providing a standardized method of assessing meibomian gland functionality, the complementary roles of the aqueous and lipid layers, and the specific treatment of NOMGD, emphasizing that the success of treatment of all forms of obstructive MGD is dependent on the relief of the obstruction.

Most patients with intestinal anisakiasis need hospitalization because anisakiasis can cause intestinal obstruction, ileus, peritonitis or intestinal perforation. We report a case of intestinal anisakiasis. A 43-year-old woman presented with symptoms of intermittent abdominal pain 2 days after eating raw fish. Her brother had eaten the same food and had been suffering from gastric anisakiasis. Abdominal ultrasonography in this patient showed localized jejunal wall thickening with dilated lumen of proximal jejunum and ascites. According to the clinical course and examinations, she was diagnosed with intestinal anisakiasis. Administration of prednisolone 5 mg/day and olopatadine hydrochloride 10 mg/day improved her symptoms quickly without hospitalization. Prednisolone was administered for 10 days, and olopatadine hydrochloride was administered for a total of 6 weeks according to ultrasonographic findings. Six months after the treatment, the abdominal ultrasonography demonstrated normal findings. This case demonstrates that ultrasonography was quite useful for the diagnosis and surveillance of intestinal anisakiasis. Furthermore, treatment with corticosteroid and an antiallergic agent could be an option for patients with intestinal anisakiasis. PMID:27403099

    Portal biliary ductopathy (PBD) is a condition in which biliary and pancreatic ducts are extrinsically compressed by collateral branches of the portal venous system, which in turn have become dilated and varicosed due to portal hypertension. While the majority of patients with PBD are asymptomatic, a minority can present with symptoms of biliary obstruction and cholangitis with the potential of developing secondary chronic liver disease. This paper reports the case of a 29 year old male presenting with acute cholangitis, in whom PBD was diagnosed radiologically. A brief review of current literature regarding the diagnosis and management of this condition will also be presented. PMID:22844197

    Obstructive sleep apnoea is an increasingly common disorder of repeated upper airway collapse during sleep, leading to oxygen desaturation and disrupted sleep. Features 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

    Genital tract reconstruction has been attempted in subfertile men with obstructive azoospermia (370 patients) or unilateral testicular obstruction (80 patients), and in vasectomised men undergoing reversal for the first (130 patients) or subsequent (32 patients) time. Histopathological changes in the obstructed testes and epididymes, and immunological responses to the sequestered spermatozoa have been studied to gain insight into possible causes of failure of surgical treatment. The results of surgery have been assessed by follow-up sperm counts and occurrence of pregnancies in the female partners. The best results were obtained with vasectomy reversal (patency 90%, pregnancy 45%), even after failed previous attempts (patency 87%, pregnancy 37%). Epididymovasostomy gave good results with postinfective caudal blocks (patency 52%, pregnancy 38%), while postinfective vasal blocks were better corrected by total anatomical reconstruction (patency 73%, pregnancy 27%) than by transvasovasostomy (patency 9%, no pregnancies). Poor results were obtained with capital blocks (patency 12%, pregnancy 3%), in which substantial lipid accumulation was demonstrated in the ductuli efferentes; three-quarters of these patients had sinusitis, bronchitis or bronchiectasis (Young's syndrome). There is circumstantial evidence to suggest that this syndrome may be a late complication of mercury intoxication in childhood. After successful reconstruction, fertility was relatively reduced in those men who had antibodies to spermatozoa, particularly amongst the postinfective cases. Similarly, impaired fertility was found in men with unilateral testicular obstruction and antibodies to spermatozoa. Mononuclear cell infiltration of seminiferous tubules and rete testis was noted occasionally, supporting a diagnosis of autoimmune orchitis; although rare, this was an important observation as the sperm output became normal with adjuvant prednisolone therapy.

    Abdominal cocoon syndrome (ACS) is a rare cause of intestinal obstruction due to total or partial encapsulation of the small intestine by a fibrocollagenous membrane. Idiopathic ACS with abdominal cryptorchidism and greater omentum hypoplasia is even rarer clinically. We successfully treated a 26-year-old male case of small bowel obstruction with acute peritonitis. He was finally diagnosed with idiopathic ACS with unilateral abdominal cryptorchidism and greater omentum hypoplasia during exploratory laparotomy. He then underwent enterolysis, cryptorchidectomy, and appendectomy. He recovered gradually from the operations and early postoperative inflammatory ileus. There has been no recurrence of intestinal obstruction since the operation, and he is still in follow-up. We analyzed his clinical data and retrospectively reviewed the literature, and our findings may be helpful for the clinical diagnosis and treatment on ACS. PMID:27239122

    Pancreatic cancer and cholangiocarcinoma are the most common causes of malignant biliary obstruction. They are diseases of increasing incidence and unfavorable prognosis. Only patients with localized disease indicated for surgery have a chance of long-term survival. These patients represent less than 20 % of all patients, despite the progress in our diagnostic abilities.Locally advanced and metastatic tumors are treated with palliative chemotherapy or chemoradiotherapy; the results of such treatments are unsatisfactory. The average survival of patients with unresectable disease is 6 months and only 5-10 % of patients survive 5 years.Biliary drainage is an integral part of palliative treatment. Endoscopically or percutaneosly placed stents improve quality of life, decrease cholestasis and pruritus, but do not significantly improve survival. Biliary stents get occluded over time, possibly resulting in acute cholangitis and require repeated replacement.Photodynamic therapy and radiofrequency ablation, locally active endoscopic methods, have been increasingly used in recent years in palliative treatment of patients with malignant biliary obstruction. In photodynamic therapy, photosensitizer accumulates in tumor tissue and is activated 48 hours later by light of a specific wave length. Application of low voltage high frequency current during radiofrequency ablation results in tissue destruction by heat. Local ablation techniques can have a significant impact in a large group of patients with malignant biliary obstruction, leading to improved prognosis, quality of life and stent patency.

  12. Strategies for preserving intestinal length in the short-bowel syndrome

    1987-03-01

    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.

    The authors present the results of surgical treatment of 106 elderly and senile patients. In 30 patients admitted in a extremely severe condition the acute intestinal obstruction was combined with peritonitis. Postoperative mortality in this group of patients was 86.7% in spite of intensive treatment. In 28 patients generalization of the process was detected and they were given palliative interventions for liquidation of acute intestinal obstruction. Postoperative mortality in this group was 39.2%. Conventional radical operations were fulfilled on 48 patients. Postoperative mortality in this group was 20.8%. Later on the intestinal patency was reestablished in 15 patients. The data obtained show the possibility to widen the indications to radical operative interventions and to improve results of treatment of such patients. PMID:14997809

    While the management of asymptomatic body packers is mainly conservative, few individuals will require surgery for acute toxicity related to packets rupture, intestinal obstruction or very slow progression of the packages. Obstruction of the lower oesophagus or stomach is not frequently reported. We report the case of a 49-year-old woman who had ingested 92 cocaine-containing packages. She was admitted to the hospital after opioid syndrome related to the intake of morphine and codeine to decrease intestinal transit. The presence of more than 80 packages was suspected in the stomach on the initial abdomen computed tomography. Due to the absence of progression of the packages after four days of well-conducted laxative therapy and to major gastric distension at abdomen tomography, surgery was decided and gastrotomy allowed the evacuation of 80 packages that were still present in the stomach or in the lower oesophagus. In addition, 12 other packages had been retrieved either after laxative therapy (9) or by evacuation via the anal canal (3) after palpation of the intestine during the surgical procedure. No complication was observed. PMID:25287802

    A 54-year-old female experienced rapid respiratory failure while being transported in an ambulance to our emergency department for evaluation and management of constipation and abdominal pain. The patient was on treatment with distigmine bromide for postoperative urination disorder and magnesium oxide for constipation. Increased salivary secretions, diminished respiratory excursion, type 2 respiratory failure (PaCO2 : 65 mmHg), low serum cholinesterase, and hypermagnesemia were detected. Imaging studies revealed that the patient had bilateral aspiration pneumonia, fecal impaction in the rectum, and a distended colon causing ileus. The patient was mechanically ventilated and was weaned off the ventilator on day 3. Therapeutic drug monitoring after discharge revealed that the serum level of distigmine bromide on admission was markedly elevated (377.8 ng/mL vs. the normal therapeutic level of 5-10 ng/mL). Distigmine bromide induced a cholinergic crisis with a resultant increase in airway secretions and respiratory failure. In this particular case, orally administered distigmine bromide was excessively absorbed because of prolonged intestinal transit time secondary to fecal impaction and sluggish bowel movement; this caused a cholinergic crisis and hypermagnesemia contributing to respiratory failure. Clinicians should be aware that bowel obstruction in a patient treated with distigmine bromide can increase the risk of a cholinergic crisis. PMID:27255021

    The endoderm gives rise to the lining of the esophagus, stomach and intestines, as well as associated organs. To generate a functional intestine, a series of highly orchestrated developmental processes must occur. In this review, we attempt to cover major events during intestinal development from gastrulation to birth, including endoderm formation, gut tube growth and patterning, intestinal morphogenesis, epithelial reorganization, villus emergence as well as proliferation and cytodifferentiation. Our discussion includes morphological and anatomical changes during intestinal development as well as molecular mechanisms regulating these processes. PMID:21246663

    We present the case of a 33-year-old female who presented intestinal obstruction at the 7th month of pregnancy. She was complaining of abdominal pain with paroxysms, nausea and vomiting. When the symptoms worsened, we performed a CT-scan, which revealed suspected intestinal obstruction in a context of intestinal malrotation (IM). Conservative therapy failed and she required emergency laparotomy beginning with a caesarean section. The surgery revealed a peritoneal defect due to the IM through which the jejunum and ileum were incarcerated and strangulated. The incarcerated bowel was reduced and intestinal colour quickly returned to normal. Primary closure of the peritoneal defect was thus performed and the post-operative course was uneventful for the mother and the baby, who was admitted to the neonatal intensive care unit.

    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

    PubMed

    Brusasco, Vito; Martinez, Fernando

    2014-01-01

    COPD is characterized by airflow limitation that is not fully reversible. The morphological basis for airflow obstruction results from a varying combination of obstructive changes in peripheral conducting airways and destructive changes in respiratory bronchioles, alveolar ducts, and alveoli. A reduction of vascularity within the alveolar septa has been reported in emphysema. Typical physiological changes reflect these structural abnormalities. Spirometry documents airflow obstruction when the FEV1/FVC ratio is reduced below the lower limit of normality, although in early disease stages FEV1 and airway conductance are not affected. Current guidelines recommend testing for bronchoreversibility at least once and the postbronchodilator FEV1/FVC be used for COPD diagnosis; the nature of bronchodilator response remains controversial, however. One major functional consequence of altered lung mechanics is lung hyperinflation. FRC may increase as a result of static or dynamic mechanisms, or both. The link between dynamic lung hyperinflation and expiratory flow limitation during tidal breathing has been demonstrated. Hyperinflation may increase the load on inspiratory muscles, with resulting length adaptation of diaphragm. Reduction of exercise tolerance is frequently noted, with compelling evidence that breathlessness and altered lung mechanics play a major role. Lung function measurements have been traditionally used as prognostic indices and to monitor disease progression; FEV1 has been most widely used. An increase in FVC is also considered as proof of bronchodilatation. Decades of work has provided insight into the histological, functional, and biological features of COPD. This has provided a clearer understanding of important pathobiological processes and has provided additional therapeutic options. PMID:24692133

    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.

    The management of obstructed defecation syndrome (ODS) is mainly conservative and mainly consists of fiber diet, bulking laxatives, rectal irrigation or hydrocolontherapy, biofeedback, transanal electrostimulation, yoga and psychotherapy. According to our experience, nearly 20% of the patients need surgical treatment. If we consider ODS an "iceberg syndrome", with "emerging rocks", rectocele and rectal internal mucosal prolapse, that may benefit from surgery, at least two out of ten patients also has "underwater rocks" or occult disorders, such as anismus, rectal hyposensation and anxiety/depression, which mostly require conservative treatment. Rectal prolapse excision or obliterative suture, rectocele and/or enterocele repair, retrograde Malone's enema and partial myotomy of the puborectalis muscle are effective in selected cases. Laparoscopic ventral sacral colporectopexy may be an effective surgical option. Stapled transanal rectal resection may lead to severe complications. The Transtar procedure seems to be safer, when dealing with recto-rectal intussusception. A multidisciplinary approach to ODS provides the best results. PMID:25632177

    Megacystis Microcolon Intestinal Hypoperistalsis Syndrome (MMIHS) is a rare and the most severe form of functional intestinal obstruction in the newborn. The characteristic features of this congenital and fatal disease are abdominal distension, absent or decreased bowel peristalsis. Abdominal distension is a consequence of the distended, unobstructed urinary bladder with or without hydronephrosis. We present a case of female newborn with antenatal ultrasound revealing a large cystic mass in pelvic with urinary tract origin, abdominal distension, a peristalsis of the intestine and micro colon.

    Megacystis Microcolon Intestinal Hypoperistalsis Syndrom (MMIHS) is a quite rare congenital and fatal disease which was firstly defined by Berdon and his colleagues. It appears through a widely enlarged bladder and microcolon and its cause is unknown (Berdon et al., 1976; Carmelo et al., 2005; Makhija et al., 1999; Loening-Baucke and Kimura 1999; Redman et al., 1984; Hsu et al., 2003; Yigit et al., 1996; Srikanth et al., 1993). The disease is found in females three or four times more than in males (Srikanth et al., 1993; Sen et al., 1993; Hirato et al., 2003). Most of the cases die within the early months of their lives (Yigit et al., 1996; Srikanth et al., 1993; Sen et al., 1993; Hirato et al., 2003). We present the case of a female newborn with antenatal ultrasound revealing intestinal mass and bilateral hydroureteronephrosis. The case was admitted for intestinal obstruction after birth.

    Intestinal ultrasound has become an established and valid diagnostic method for inflammatory bowel disease, diverticulitis, appendicitis, bowel obstruction, perforation and intussusception. However, little is known about sonographic findings in other rarer intestinal diseases. Ultrasound may display the transformation of the intestinal wall from a normal to a pathological state both in inflammatory and neoplastic disease. Besides demonstrating the transmural aspect, it also shows the mesenteric reaction as well as complications such as fistula, abscesses, stenosis, or ileus. Furthermore, in some diseases intestinal ultrasound may serve as a diagnostic clue if typical patterns of the bowel wall and impaired peristalsis can be demonstrated. This may lead to an important reduction of invasive and expensive (follow-up) procedures. The information gained by ultrasound regarding intestinal disease, however, is as important and valid as e. g. in case of focal lesions of the liver. Serving as tertiary referral centers for a broad spectrum of intestinal diseases, we therefore report some aspects of ultrasound in patients with less often recognized diseases. The article is divided into two parts, the first focusing on examination techniques, infectious diseases and celiac sprue and the second on hereditary, vascular and neoplastic diseases and varia.

    Decompression of the biliary system in patients with malignant biliary obstruction has been widely accepted and implemented as part of the care. Despite a wealth of literature, there remains a significant amount of uncertainty as to which approach would be most appropriate in different clinical settings. This review covers stenting of the biliary system in cases of resectable or palliative malignant biliary obstruction, potential candidates for biliary drainage, technical aspects of the procedure, as well as management of biliary stent dysfunction. Furthermore, periprocedural considerations including proper mapping of the location of obstruction and the use of antibiotics are addressed. PMID:26431598

    Tonal noise generated by axial fans at the Blade Passage Frequency and its harmonics is a source of discomfort for low-speed fans used in many cooling and ventilation applications. The noise control approach presented here is based on the interference between the unsteady aerodynamic blade loads responsible for tonal noise generation and secondary aerodynamic loads generated in the rotor plane by fixed, carefully positioned, small obstructions in the upstream flow. Although not strictly active control, the magnitude and phase of the secondary tonal noise can be adjusted by varying the axial distance between the rotor and the obstruction, and the circumferential position of the obstruction, respectively. An optimal position of the obstruction generally exists, that minimizes the total noise at a given frequency. This paper establishes a practical method for automatic positioning of such control obstructions. In a first step, the method searches for the optimal axial distance between the rotor and the obstruction using a slowly rotating control obstruction. The modulation created by the rotation of the obstruction allows for the primary and secondary noises to be distinguished in the frequency response of the sound field. The steepest descent algorithm is used to find the optimal axial distance, for which the magnitudes of the primary and secondary tonal noise are equal at the error microphone. Then, the optimal angular position of the obstruction is obtained by slowly rotating the obstruction until minimal total noise is achieved. Finally, it is shown that at the optimal axial and angular position, the BPF tone, which produced the largest area in the loudness pattern, has been greatly reduced.

    Achalasia is an idiopathic motility disorder of the oesophagus of increasing incidence. It is characterized by aperistalsis of the lower oesophagus and failure of relaxation of the lower oesophageal sphincter. Patients classically present with chronic symptoms of dysphagia, chest pain, weight loss and regurgitation, and they commonly suffer pulmonary complications such as recurrent microaspiration of static, retained food contents of the upper oesophagus. However, it has also been described, uncommonly, to present with megaoesophagus and secondary tracheal compression. We present a case of megaoesophagus secondary to achalasia which presented with stridor and signs of acute superior vena caval obstruction. PMID:26933001

    The intestinal epithelium is composed of specialized epithelial cells that form a physical and biochemical barrier to commensal and pathogenic microorganisms. However, dysregulation of the epithelial barrier function can lead to increased intestinal permeability and bacterial translocation across the intestinal mucosa, which contributes to local and systemic immune activation. The increase in these parameters is associated with inflammatory bowel disease, physical exercise under heat stress, intestinal obstruction, ischemia, and mucositis, among other conditions. Lately, there has been growing interest in immunomodulatory nutrients and probiotics that can regulate host immune and inflammatory responses and possibly restore the intestinal barrier. Immunomodulators such as amino acids (glutamine, arginine, tryptophan, and citrulline), fatty acids (short-chain and omega-3 fatty acids and conjugated linoleic acids), and probiotics (Bifidobacterium, Saccharomyces, and Lactobacillus) have been reported in the literature. Here, we review the critical roles of immunomodulatory nutrients in supporting gut barrier integrity and function. PMID:25660317

    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

    CHRONIC OBSTRUCTIVE pulmonary diseases (COPD) affect 14 per cent of the population over 40 years of age. With an ageing population, the number of those requiring care for COPD is expected to increase, having a significant effect on health-care resources. COPD is projected to become the third leading cause of death globally by 2020. This disease has a major impact on economic and social well-being, and on quality of life. It is regarded as largely preventable but, once developed, is a progressive and complex condition characterised by frequent exacerbations and co-morbidities. Smoking is the primary cause of COPD but up to 30 per cent of those with COPD have never smoked. It is increasingly recognised COPD may have its origins prenatally and in early childhood. Treating exacerbations, improving exercise capacity, and delaying progression of disease are key management strategies. No curative or disease modifying therapies are available. Nurses are essential in providing comprehensive care to patients in both acute care and for long-term management. They also have a vital role to play in preserving healthy lung function in the early years of life to reduce the risk of COPD in older age. PMID:27514228

    The management of obstructed defecation syndrome (ODS) is mainly conservative and mainly consists of fiber diet, bulking laxatives, rectal irrigation or hydrocolontherapy, biofeedback, transanal electrostimulation, yoga and psychotherapy. According to our experience, nearly 20% of the patients need surgical treatment. If we consider ODS an “iceberg syndrome”, with “emerging rocks”, rectocele and rectal internal mucosal prolapse, that may benefit from surgery, at least two out of ten patients also has “underwater rocks” or occult disorders, such as anismus, rectal hyposensation and anxiety/depression, which mostly require conservative treatment. Rectal prolapse excision or obliterative suture, rectocele and/or enterocele repair, retrograde Malone’s enema and partial myotomy of the puborectalis muscle are effective in selected cases. Laparoscopic ventral sacral colporectopexy may be an effective surgical option. Stapled transanal rectal resection may lead to severe complications. The Transtar procedure seems to be safer, when dealing with recto-rectal intussusception. A multidisciplinary approach to ODS provides the best results. PMID:25632177

  3. Intestinal colonization resistance

    2013-01-01

    Dense, complex microbial communities, collectively termed the microbiota, occupy a diverse array of niches along the length of the mammalian intestinal tract. During health and in the absence of antibiotic exposure the microbiota can effectively inhibit colonization and overgrowth by invading microbes such as pathogens. This phenomenon is called ‘colonization resistance’ and is associated with a stable and diverse microbiota in tandem with a controlled lack of inflammation, and involves specific interactions between the mucosal immune system and the microbiota. Here we overview the microbial ecology of the healthy mammalian intestinal tract and highlight the microbe–microbe and microbe–host interactions that promote colonization resistance. Emerging themes highlight immunological (T helper type 17/regulatory T-cell balance), microbiota (diverse and abundant) and metabolic (short-chain fatty acid) signatures of intestinal health and colonization resistance. Intestinal pathogens use specific virulence factors or exploit antibiotic use to subvert colonization resistance for their own benefit by triggering inflammation to disrupt the harmony of the intestinal ecosystem. A holistic view that incorporates immunological and microbiological facets of the intestinal ecosystem should facilitate the development of immunomodulatory and microbe-modulatory therapies that promote intestinal homeostasis and colonization resistance.

    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. PMID:26595891

    Rapunzel syndrome is an extremely rare variant of Trichobezoar. Trichobezoar commonly occurs in patients with psychiatric disturbances as trichophagia (morbid habit of chewing the hair) and Trichotillomania (habit of hair pulling). Bezoars are commonly found in the stomach. In very rare cases of Rapunzel syndrome, hair extends through the pylorus into the small bowel and very uncommonly in large intestine causing symptoms and signs of partial or complete intestinal obstruction. A case report of a rare variant of Rapunzel syndrome, where ball of hairs in small bowel with its tail extending in caecum and ascending colon causing acute small bowel obstruction, is reported in a 13-year-old girl.

    A congenital membrane without intestinal malrotation is a rare cause of duodenal obstruction. Here we present an 11-year-old girl who had suffered from intermittent abdominal cramping pain and vomiting for more than 5 years. The image studies, including a plain abdomen roentgenogram and sonogram, showed no definite diagnosis. The upper gastrointestinal series and small bowel series showed the contrast was static over the third portion of the duodenum and the descending colon pulled up toward the epigastric area. Laparoscopic exploration revealed a congenital membrane extending from the right-side paraduodenal peritoneum through the third portion of the duodenum to the descending colon, which had caused obstruction of the third portion of the duodenum and malpositioning of the descending colon. To the best of our knowledge, this is the first case report in the literature where a congenital membrane caused both duodenal obstruction and malpositioning of the descending colon. PMID:23597513

    Ureteral polyps are rare causes of ureteropelvic junction (UPJ) obstruction, particularly in children. We report a nine year-old boy with UPJ obstruction initially suggestive of an obstructive urinary stone. CT showed intraureteral calcification at the UPJ and hydronephrosis. A retrograde pyelogram showed narrowing at the UPJ and partial obstruction that was found to be a ureteral polyp. This case illustrates a rare cause of UPJ obstruction that should be considered when the imaging findings and presentation are atypical for more common etiologies of ureteral obstruction.

    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.

    Intestinal failure is a condition characterized by malnutrition and/or dehydration as a result of the inadequate digestion and absorption of nutrients. The most common cause of intestinal failure is short bowel syndrome, which occurs when the functional gut mass is reduced below the level necessary for adequate nutrient and water absorption. This condition may be congenital, or may be acquired as a result of a massive resection of the small bowel. Following resection, the intestine is capable of adaptation in response to enteral nutrients as well as other trophic stimuli. Identifying factors that may enhance the process of intestinal adaptation is an exciting area of research with important potential clinical applications. PMID:16937429

    Cricoid pressure may cause airway obstruction. We investigated whether this is related to the force applied and to the technique of application. We recorded expired tidal volumes and inflation pressures during ventilation via a face-mask and oral airway in 52 female patients who were anaesthetised and about to undergo elective surgery. An inspired tidal volume of 900 ml was delivered using a ventilator. Ventilation was assessed under five different conditions: no cricoid pressure, backwards cricoid pressure applied with a force of 30 N, cricoid pressure applied in an upward and backward direction with a force of 30 N, backwards cricoid pressure with a force of 44 N and through a tracheal tube. An expired tidal volume of < 200 ml was taken to indicate airway obstruction. Airway obstruction did not occur without cricoid pressure, but did occur in one patient (2%) with cricoid pressure at 30 N, in 29 patients (56%) with 30 N applied in an upward and backward direction and in 18 (35%) patients with cricoid pressure at 44 N. Cricoid pressure applied with a force of 44 N can cause airway obstruction but if cricoid pressure is applied with a force of 30 N, airway obstruction occurs less frequently (p = 0.0001) unless the force is applied in an upward and backward direction.

    2013-01-01

    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.

    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. PMID:26374775

    A 60-year-old woman with a history of breast cancer presented with bilateral obstruction of bilaterally duplicated renal collecting systems secondary to extrinsic compression from metastatic pelvic lymphadenopathy. Bilateral JJ ureteric stents were inserted, resulting in some improvement of renal function but a failure to normalise completely. Repeat computed tomography demonstrated bilateral duplex collecting systems with persisting obstruction of the undrained moieties. Selective puncture was performed to decompress the obstructed renal moieties for bilateral nephrostomy catheter insertion. This allowed renal function to improve sufficiently for the patient to be discharged and commence chemotherapy. This is the first reported case of bilaterally obstructed partially duplicated collecting systems and it illustrates the importance of recognising anatomical variants to tailor treatment appropriately. It also highlights the important relationship between urology and interventional radiology in the management of such complex patients. PMID:26985816

    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.

    The deep circumflex iliac artery flap (DCIA) has been well described as an autograft flap used in head and neck reconstructions, particularly for large maxillary and mandibular defects. Complications, particularly at the donor site, have been well documented. Although it is considered a minor complication, herniation should not be underestimated as it can potentially lead to bowel obstruction, necessitating an emergency operation. We report a case of acute obstruction of the small bowel secondary to herniation at the donor site after harvesting a DCIA free flap for a maxillary defect, a complication that to our knowledge has been reported only once. We review the pathogenesis and possible ways to reduce the likelihood of developing this serious complication. PMID:19249144

    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. PMID:23505728

    There is a long-standing belief that disruption of the intestinal barrier function may lead to systemic and local intestinal disease. The role of increased intestinal permeability in Crohn's disease is reviewed here. 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. PMID:15669640

    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.

    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.

    After more than a century of conjecture and heated argument, the orthodontic relevance of nasal obstruction and its assumed effect on facial growth continues to be debated. Oral respiration disrupts those muscle forces exerted by tongue, cheeks and lips upon the maxillary arch. The main characteristics of the respiratory obstruction syndrome are presence of hypertrophied tonsils or adenoids, mouth breathing, open-bite, cross-bite, excessive anterior face height, incompetent lip posture, excessive appearance of maxillary anterior teeth, narrow external nares, "V" shaped maxillary arch. The purpose of this study is to evaluate relationship between nasal obstruction and severity of malocclusion. The sample analyzed in this article consisted of 49 children aged from 7 to 15 years, who pronounced difficulty in breathing through the nose. Patients and their parents were interviewed, clinical examination was performed, and measurements from dental casts and panoramic radiograph were obtained. All patients were examined by otorhinolaryngologist, and the nasal obstruction was confirmed by posterior rhinomanometry test. This study showed the significant association between nasal resistance and increased overjet (p = 0.042), open bite (p = 0.033) and maxillary crowding (p = 0.037). The tendency of greater nasal resistance was observed for the patients with the first permanent molars relationship Angle II and posterior cross-bite. PMID:12474699

    2015-01-01

    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

    Secondary diabetes is diabetes that results as a consequence of another medication, endocrine disease or hereditary disease. Secondary diabetes is very broad and diverted category among diabetes. Clinically, pancreatic diabetes is one of the most popular secondary diabetes, which provides insulin deficiency following pancreatic diseases, such as pancreatitis and pancreatic cancer. Among endocrine diseases, Cushing's syndrome and acromegaly are typical endocrine disorders causing secondary diabetes. They mainly induce insulin resistance in early stage, however, insulin deficiency is also observed in advanced stage. Steroid is the most popular drug-induced secondary diabetes. Importantly, not only oral administered steroid but also cutaneous and inhalation steroid could induce hyperglycemia. Major hereditary diabetes are MODY and mitochondrial diabetes. Concerning secondary diabetes, careful medical examination is required. PMID:26666145

    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

    Small intestine bacterial overgrowth (SIBO) is a condition characterised by nutrient malabsorption and excessive bacteria in the small intestine. It typically presents with diarrhea, flatulence and a syndrome of malabsorption (steatorrhea, macrocytic anemia). However, it may be asymptomatic in the eldery. A high index of suspicion is necessary in order to differentiate SIBO from other similar presenting disorders such as coeliac disease, lactose intolerance or the irritable bowel syndrome. A search for predisposing factor is thus necessary. These factors may be anatomical (stenosis, blind loop), or functional (intestinal hypomotility, achlorydria). The hydrogen breath test is the most frequently used diagnostic test although it lacks standardisation. The treatment of SIBO consists of eliminating predisposing factors and broad-spectrum antibiotic therapy. PMID:20214190

    Small intestinal infections are extremely common worldwide. They may be bacterial, viral, or parasitic in etiology. Most are foodborne or waterborne, with specific etiologies differing by region and with diverse pathophysiologies. Very young, very old, and immune-deficient individuals are the most vulnerable to morbidity or mortality from small intestinal infections. There have been significant advances in diagnostic sophistication with the development and early application of molecular diagnostic assays, though these tests have not become mainstream. The lack of rapid diagnoses combined with the self-limited nature of small intestinal infections has hampered the development of specific and effective treatments other than oral rehydration. Antibiotics are not indicated in the absence of an etiologic diagnosis, and not at all in the case of some infections. PMID:27168147

    Neuronal Intestinal Dysplasia type B (NID B) is a complex alteration of the enteric nervous system belonging to the group of intestinal dysganglionoses which may involve rectum, colon, and small intestine. Second only to Hirschsprung diseases (HSCR), NID B is one of the most frequent causes of chronic constipation and pseudo-obstructive intestinal dysmotility. Since NID B is often associated with HSCR and point mutations in the RET proto-oncogene have been identified in HSCR patients, we analyzed two NID B pedigrees to investigate if RET mutations might cause also the NID B phenotype. Linkage analysis demonstrated that the NID B locus is not linked to RET in the pedigrees analysed. Further genetic analyses will possibility improve the understanding of the cause and facilitate diagnostic procedures in NID B. 20 refs., 1 fig., 2 tabs.

    Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a rare, often fatal condition. Infants present with a functional obstruction of the gastrointestinal tract (GI), malrotation, microcolon, and a large nonobstructed bladder. Several features common to both MMIHS and Eagle-Barrett or prune belly syndrome (PBS) include hydronephrosis, bladder distension and laxity of the abdominal wall musculature. Additionally, MMIHS and PBS have been reported in the same family, suggesting the possibility of a common pathogenesis. MMIHS usually presents in female infants. We present a male infant diagnosed with both MMIHS and PBS. This is a unique case in which both MMIHS and true PBS are present in the same infant. PMID:15289943

    Background/Aims Chronic intestinal pseudo-obstruction (CIPO) is a disorder characterized by recurrent symptoms suggestive of obstruction such as abdominal pain, proximal distension with extremely suppressed motility in the absence of lumen-occluding lesion, whose etiology/pathophysiology is poorly understood. In this study we investigated a functionally obstructive lesion that could underlie symptoms of CIPO. Methods We studied colons surgically removed from 13 patients exhibiting clinical/pathological features of pseudo-obstruction but were unresponsive to standard medical treatments. The colons were characterized morphologically, functionally and molecularly, which were compared between regions and to 28 region-matched controls obtained from colon cancer patients. Results The colons with pseudo-obstruction exhibited persistent luminal distension proximally, where the smooth muscle was hypertrophied with changes in the cell phenotypes. Distinct luminal narrowing was observed near the distal end of the dilated region, close to the splenic flexure, previously referred to as the “transition zone (TZ)” between the dilated and non-dilated loops. Circular muscles from the TZ responded less to depolarization and cholinergic stimulation, which was associated with down-regulation of L-type calcium channel expression. Smooth muscle contractile protein was also downregulated. Myenteric ganglia and neuronal nitric oxide synthase (nNOS) positive cells were deficient, more severely in the TZ region. Interstitial cells of Cajal was relatively less affected. Conclusions The TZ may be the principal site of functional obstruction, leading to proximal distension and smooth muscle hypertrophy, in which partial nNOS depletion could play a key role. The neuromuscular abnormalities probably synergistically contributed to the extremely suppressed motility observed in the colonic pseudo-obstruction. PMID:26424041

    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. PMID:26934740

The quest is still on and, unfortunately, clinical practice has not dramatically changed. The investigation of intestinal malabsorption is directed by the patient's history and baseline tests. Endoscopy and small bowel biopsies play a major role although non-invasive tests are favored and often performed early on the diagnostic algorithm, especially in paediatric and fragile elderly patients.

    Small intestinal bacterial overgrowth (SIBO), defined as excessive bacteria in the small intestine, remains a poorly understood disease. Initially thought to occur in only a small number of patients, it is now apparent that this disorder is more prevalent than previously thought. Patients with SIBO vary in presentation, from being only mildly symptomatic to suffering from chronic diarrhea, weight loss, and malabsorption. A number of diagnostic tests are currently available, although the optimal treatment regimen remains elusive. Recently there has been renewed interest in SIBO and its putative association with irritable bowel syndrome. In this comprehensive review, we will discuss the epidemiology, pathogenesis, clinical manifestations, diagnosis, and treatment of SIBO. PMID:21960820

    Multiple intestinal atresia (MIA) is a rare cause of bowel obstruction that is sometimes associated with a combined immunodeficiency (CID), leading to increased susceptibility to infections. The factors underlying this rare disease are poorly understood. We characterized the immunological and intestinal features of 6 unrelated MIA-CID patients. All patients displayed a profound, generalized lymphocytopenia, with few lymphocytes present in the lymph nodes. The thymus was hypoplastic and exhibited an abnormal distribution of epithelial cells. Patients also had profound disruption of the epithelial barrier along the entire gastrointestinal tract. Using linkage analysis and whole-exome sequencing, we identified 10 mutations in tetratricopeptide repeat domain–7A (TTC7A), all of which potentially abrogate TTC7A expression. Intestinal organoid cultures from patient biopsies displayed an inversion of apicobasal polarity of the epithelial cells that was normalized by pharmacological inhibition of Rho kinase. Our data indicate that TTC7A deficiency results in increased Rho kinase activity, which disrupts polarity, growth, and differentiation of intestinal epithelial cells, and which impairs immune cell homeostasis, thereby promoting MIA-CID development.

    Many published data indicate that a relevant proportion of cases of asthma and chronic obstructive pulmonary disease (COPD) are caused by occupational exposure. That phenomenon results in many negative economic consequences, including, apart from considerable medical costs, also costs owing to unemployment and claiming for compensation, which are frequent in patients suffering from that illnesses. Hence, it is probable that increasing prevalence of those diseases may result in higher economical costs. The effectiveness of primary and secondary prevention in reduction of costs concerning occupational asthma and COPD has been proved. Only effective prophylaxis may decrease individual and public costs related to both diseases. PMID:15524015

    Intestinal volvulus was recognized as the cause of death in 18 cetaceans, including 8 species of toothed whales (suborder Odontoceti). Cases originated from 11 institutions from around the world and included both captive (n = 9) and free-ranging (n = 9) animals. When the clinical history was available (n = 9), animals consistently demonstrated acute dullness 1 to 5 days prior to death. In 3 of these animals (33%), there was a history of chronic gastrointestinal illness. The pathological findings were similar to those described in other animal species and humans, and consisted of intestinal volvulus and a well-demarcated segment of distended, congested, and edematous intestine with gas and bloody fluid contents. Associated lesions included congested and edematous mesentery and mesenteric lymph nodes, and often serofibrinous or hemorrhagic abdominal effusion. The volvulus involved the cranial part of the intestines in 85% (11 of 13). Potential predisposing causes were recognized in most cases (13 of 18, 72%) but were variable. Further studies investigating predisposing factors are necessary to help prevent occurrence and enhance early clinical diagnosis and management of the condition. PMID:23150643

It is most common in children aged 5 to 14 years.The most commonly reported symptoms are pruritus in the perianal region, abdominal pain, urinary tract infection, insomnia, irritability, salpingitis, and appendicitis, whereas intestinal obstruction is a very rare but would be considered to perform the right instrumental examination avoiding unnecessary surgical exploration.We report a case of an 8-year-old boy with an intestinal occlusion due to a colonic intussusception by Enterobius vermicularis managed conservatively.

    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.

    Ejaculatory duct obstruction (EDO) remains a rare but surgically correctable cause of male sexual dysfunction and male infertility due to obstructive azoospermia, diagnosed in up to 5% of infertile men. EDO should, therefore, be considered within the list of differential diagnoses for men undergoing infertility investigations, with work up including clinical examination, transurethral ultrasonography, semen analysis, chromotubation, seminal vesiculography and seminal vesicle aspiration. Obstruction can be limited to the distal ends of the ducts or it can extend proximally to include the terminal portions of the vasa deferentia, with the site and length of the obstruction having implications for surgical intervention. Early endoscopic treatment can reverse symptoms and prevent the progression of partial obstruction to bilateral, complete obstruction, and transurethral resection of the ejaculatory duct remains the main treatment option for EDO. Alternative treatment options include endoscopic laser-assisted resection of the ducts, antegrade seminal-vesicle lavage to relieve EDO secondary to inspissated material or calculi, or dilatation of the ejaculatory ducts using 9F seminal vesicoscopy or balloon.

    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

    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.

    2016-01-01

    Intussusception of small bowel is considered a rare cause of bowel obstruction in adults accounting for only about 1% of bowel obstruction in adults. Intussusception in adults is uncommon with 95% cases of intussusceptions occurring in children. Adult intussusception from small intestinal lymphoma is also rare with only 36 cases reported in the literature between 2000 and 2011. Plasmablastic lymphoma (PBL) is an aggressive lymphoid neoplasm usually seen in the oral cavity in the clinical setting of human immunodeficiency virus (HIV) infection. Plasmablastic lymphoma of the small intestine is extremely rare. Here, we report a case of plasmablastic lymphoma of small bowel with ileoileal intussusception in an HIV-negative immunocompetent male patient. PMID:27134931

    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.

    Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a rare and severe form of neonatal functional bowel obstruction. Affected neonates present with vomiting, an overdistended abdomen, and a huge bladder after birth, and they usually die early in life despite intensive medical and/or surgical management. We report the case of a girl aged 3 years 7 months who had MMIHS with severe psychomotor retardation; autopsy was performed after her death. PMID:12238913

  1. 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.

    Maternal ultrasound is a routine examination in prenatal evaluation. The number of fetal abnormalities detected has been increasing, and includes fetal hydronephrosis which is secondary to ureteropelvic junction obstruction in 80% of cases. We report a case of a 1-year-old female infant with hydronephrosis prenatally detected by ultrasound. After close postnatal follow-up and diagnosis, she eventually underwent a definitive reconstructive procedure. This is the first reported case of a bilateral ureteropelvic junction obstruction of the upper moieties of a duplex collecting system. PMID:18631901

    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

    Altered motility of the intestine after laparotomy, adynamic bowel segments, blind bowel loops following bypass operations, or diverticula may cause pathological growth of intestinal microflora and thus lead to contaminated small bowel syndrome (CSBS). As a result of malabsorption in the jejunum and ileum, loss of weight, growth arrest, diarrhea, steatorrhea, megaloblastic anemia, and hypoproteinemia may occur. In addition to these, the acute symptoms of small bowel contamination, intestinal obstruction and secretory diarrhea, are less well known. A stenosis in the terminal ileum was experimentally created in Göttingen minipigs and the bacterial flora of the small bowel assessed by quantitative cultures. After 3 months the number of aerobic and anaerobic bacteria in the pre- and poststenotic region had increased by a factor of 10(2)-10(5). The acute form of CSBS was diagnosed by microbiological examination of gastric samples in 14 children. After the children were treated with orally and intravenously administered antibiotics, the symptoms disappeared within 12-36 h. Reoperations for small bowel obstruction can be avoided by conservative treatment of CSBS with antibiotics. PMID:2513601

    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.

    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.

    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

    1971-01-01

    Intestinal absorption of the monoglutamate form of the principal dietary and circulating folate compound, 5-methyltetrahydrofolic acid (5-MTHF), was studied in the rat utilizing a synthetic highly purified radiolabeled diastereoisomer. Chromatography confirmed that the compound was not altered after transfer from the mucosa to the serosa. Accumulation against a concentration gradient was not observed in duodenal, jejunal, or ileal segments at 5-MTHF concentration from 0.5 to 500 nmoles/liter. Unidirectional transmural flux determination also did not indicate a significant net flux. Mucosal to serosal transfer of 5-MTHF was similar in all segments of the intestine and increased in a linear fashion with increased initial mucosal concentrations. Further, no alteration in 5-MTHF transfer was found when studied in the presence of metabolic inhibitors or folate compounds. These results indicate that 5-MTHF is not absorbed by the rat small intestine by a carrier-mediated system and suggest that 5-MTHF transfer most likely represents diffusion. Images PMID:5564397

    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. PMID:25817461

    Objective: To investigate feasibility and safety of stent implantation technique through percutaneous endoscopic gastrostomy (PEG)-like pathway for treatment of malignant gastroduodenal obstructions. Methods: Twelve patients with malignant gastroduodenal obstructions accepted PEG-like operations. A stent implantation pathway was established in abdominal wall under endoscopic guide. A guide wire and a stent release device were introduced through this pathway followed by an intestinal stent implantation. After operation, efficacy and safety of this technique were assessed by collecting data such as operation time, complications, postoperative medication, and hospitalization time during postoperative 2-12 months of follow-up. Results: Twelve patients were successfully treated with stent implantation technique through PEG-like pathway for the first time. The average operation time was 31 minutes. No severe complications occurred during treatment. On the fourth days after operation, patents were give liquid diet and treatment of rehydration, acid suppression, hemostasis and anti-inflammation. The average hospitalization time was 5 days. The follow-up time was 2-12 months. Twelve (100%) patients achieved complete remissions. The stent related complications and obstruction did not appear within 2 months after operations. The quality of life improved significantly. Conclusion: The stent implantation technique through PEG-like pathway for treatment of malignant gastroduodenal obstruction is a feasible, effective, and safe choice. PMID:26550402

    Arthrogryposis is a rare condition characterised by multiple congenital joint contractures. We present a case of a 10-year-old child with arthrogryposis and snoring. Polysomnography revealed significant obstructive sleep apnoea and hypoventilation that improved but did not completely resolve with adenotonsillectomy. With continuous positive airway pressure (CPAP) therapy, there was full resolution of all sleep disordered breathing. Initially, the patient admitted to difficulty tolerating nasal CPAP at home. However, she steadily improved adherence to therapy and admitted that with nasal CPAP use for the whole night, she felt more energised during the daytime. PMID:24907203

    Patients with nonobstructive hypertrophic cardiomyopathy (HC) are considered low risk, generally not requiring aggressive intervention. However, nonobstructive and labile-obstructive HC have been traditionally classified together, and it is unknown if these 2 subgroups have distinct risk profiles. We compared cardiovascular outcomes in 293 patients HC (96 nonobstructive, 114 labile-obstructive, and 83 obstructive) referred for exercise echocardiography and magnetic resonance imaging and followed for 3.3 ± 3.6 years. A subgroup (34 nonobstructive, 28 labile-obstructive, 21 obstructive) underwent positron emission tomography. The mean number of sudden cardiac death risk factors was similar among groups (nonobstructive: 1.4 vs labile-obstructive: 1.2 vs obstructive: 1.4 risk factors, p = 0.2). Prevalence of late gadolinium enhancement (LGE) was similar across groups but more non-obstructive patients had late gadolinium enhancement ≥20% of myocardial mass (23 [30%] vs 19 [18%] labile-obstructive and 8 [11%] obstructive, p = 0.01]. Fewer labile-obstructive patients had regional positron emission tomography perfusion abnormalities (12 [46%] vs nonobstructive 30 [81%] and obstructive 17 [85%], p = 0.003]. During follow-up, 60 events were recorded (36 ventricular tachycardia/ventricular fibrillation, including 30 defibrillator discharges, 12 heart failure worsening, and 2 deaths). Nonobstructive patients were at greater risk of VT/VF at follow-up, compared to labile obstructive (hazed ratio 0.18, 95% confidence interval 0.04 to 0.84, p = 0.03) and the risk persisted after adjusting for age, gender, syncope, family history of sudden cardiac death, abnormal blood pressure response, and septum ≥3 cm (p = 0.04). Appropriate defibrillator discharges were more frequent in nonobstructive (8 [18%]) compared to labile-obstructive (0 [0%], p = 0.02) patients. In conclusion, nonobstructive hemodynamics is associated with more pronounced fibrosis and ischemia than labile-obstructive

    Chemotherapy-induced neurotoxicity is a serious complication of cancer treatment. Oxaliplatin, a third-generation platinum drug, has become one of the first-line therapies used in the treatment of metastatic colorectal cancer. Peripheral neuropathy is a common complication of platinum-based chemotherapy. Most commonly a sensory neuropathy occurs with cold-triggered symptoms in the acute phase and numbness and painful paresthesias as a late presentation. Autonomic neurotoxicity and late presentation, months after cessation of the therapy, has rarely been described. We report a patient who clinically presented with a pseudo-obstruction months after treatment with oxaliplatin for metastatic colorectal cancer. Intestinal adhesions and relapsing malignancy were carefully excluded. By exclusion the pseudo-obstruction was attributed to a toxic oxaliplatin-induced autonomic neuropathy which slowly improved during months of follow-up. PMID:25523317

    Intra-abdominal adhesions following abdominal surgery represent a major unsolved problem. They are the first cause of small bowel obstruction. Diagnosis is based on clinical evaluation, water-soluble contrast follow-through and computed tomography scan. For patients presenting no signs of strangulation, peritonitis or severe intestinal impairment there is good evidence to support non-operative management. Open surgery is the preferred method for the surgical treatment of adhesive small bowel obstruction, in case of suspected strangulation or after failed conservative management, but laparoscopy is gaining widespread acceptance especially in selected group of patients. "Good" surgical technique and anti-adhesive barriers are the main current concepts of adhesion prevention. We discuss current knowledge in modern diagnosis and evolving strategies for management and prevention that are leading to stratified care for patients. PMID:27022449

    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

    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

We present a case of a 45-year-old female with emotionally unstable personality disorder (borderline type) presenting with partial intestinal obstruction 5 years after the known ingestion of serrated metallic scissors. In the asymptomatic interim a conservative approach of tracking the blades radiologically was taken. Following discussion, we conclude the following: early surgical intervention is encouraged if natural passage does not occur within 3 days following ingestion, and that any concurrent surgical needs should be addressed at this time.

    Ingestion of foreign bodies can be a common problem especially among children, alcoholics, psychiatric patients, and senile patients, but ingestion of a metallic dinner fork is uncommon. Foreign bodies with smooth edges usually do not pose significant problems, but a sharp foreign object that is not retrieved at the earliest may penetrate the wall and cause complications. Ingested foreign bodies usually pass the intestinal tract without problems, and perforation occurs in less than 1%. In this paper, a case of rare gastric outlet obstruction due to a dinner fork, which was ingested 25 days before, is reported. PMID:20849060

  14. Intestinal transplantation: living related.

    PubMed

    Pollard, S G

    1997-01-01

    The use of live donors in intestinal transplantation could potentially both reduce the severity of rejection responses against this highly immunogenic organ by better tissue matching and also reduce cold ischaemia times. These two advantages over cadaveric grafts could preserve mucosal integrity and reduce the risk of systemic sepsis from bacterial translocation. The disadvantages of live donation are the inherent risk to the donor and the compromise of using a shorter graft. Although only a handful of such cases have been performed, the success rate has been high and this is a therapeutic modality which should be explored further. PMID:9536535

    2001-08-15

    Ultrasonography at 23 weeks of gestation documented the presence of megacystis with horseshoe kidney, microcolon, intestinal malrotation, and decreased amniotic fluid volume. After pregnancy termination, an autopsy was performed. The external phenotype was diagnostic of the trisomy 18 syndrome confirmed by chromosome examination. The fetus also had a massively distended bladder with parchment-thin wall, microcolon, intestinal malrotation but no urethral obstruction or hydronephrosis. No ganglion cells were present in the colon or bladder. This has not been mentioned in other reported cases and, therefore, suggests pathogenic heterogeneity. The megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a rare autosomal recessive condition of unknown pathogenesis whose genes map to 15q24. Thus, its previously undescribed presence in trisomy 18 further suggests etiologic heterogeneity. PMID:11484210

    Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is characterized by prenatal-onset distended urinary bladder with functional intestinal obstruction, requiring extensive surgical intervention for survival. While it is believed to be an autosomal recessive disorder, most cases are sporadic. Through whole-exome sequencing in a child with MMIHS, we identified a de novo mutation, p.R178L, in the gene encoding the smooth muscle gamma-2 actin, ACTG2. We subsequently detected another de novo ACTG2 mutation, p.R178C, in an additional child with MMIHS. Actg2 transcripts were primarily found in murine urinary bladder and intestinal tissues. Structural analysis and functional experiments suggested that both ACTG2 mutants interfere with proper polymerization of ACTG2 into thin filaments, leading to impaired contractility of the smooth muscle. In conclusion, our study suggests a pathogenic mechanism for MMIHS by identifying causative ACTG2 mutations. PMID:24337657

    Chronic obstructive pulmonary disease (COPD) is a major public health problem, and cigarette smoke (CS) is the primary risk factor. The pathology is often observed in the lung, but COPD is also associated with intestinal barrier disruption, although the underlying mechanisms are poorly understood. To address this, a CS‑exposed rat model was evaluated in the present study by analyzing small intestinal gene expression using reverse transcription‑quantitative polymerase chain reaction. CS exposure caused upregulation of the nicotinamide adenine dinucleotide phosphate‑oxidase subunits nox2 and p22phox in the small intestine, while the antioxidative enzyme superoxide dismutase was downregulated. CS exposure also increased bax expression and decreased bcl‑2 expression. This was associated with an elevation of hypoxia‑inducible factor (HIF)‑1α. Claudin‑1 was decreased and claudin‑2 increased, indicating a loosening of small intestinal tight junctions (TJs). These data suggest that during the development of COPD, HIF‑1α expression is altered in the small intestine, which may be associated with the increased oxidative stress and apoptosis, eventually resulting in disruption of the intestinal TJs.

  18. Lubiprostone Decreases Mouse Colonic Inner Mucus Layer Thickness and Alters Intestinal Microbiota

    PubMed Central

    Musch, Mark W.; Wang, Yunwei; Claud, Erika C.

    2013-01-01

    Background Lubiprostone has been used to treat constipation through its effects to stimulate Cl− secretion, resulting in water and electrolyte secretion. Aim Potential associated changes in intestinal mucus and the colonizing bacteria (microbiome) have not been studied. As mucus obstructions may play a role in cystic fibrosis, the hypothesis that lubiprostone alters intestinal mucus and the microbiome was investigated. Methods Ion transport studies were performed ex vivo. For mucus and microbiome studies, mice were gavaged daily with lubiprostone or vehicle. Mucin from intestinal sections was analyzed in Carnoy’s fixed tissues stained with Alcian blue. Microbiome composition was analyzed by 16S rRNA gene-based sequencing. Results Lubiprostone stimulated short circuit current in all mouse intestinal segments after both serosal and mucosal additions, albeit at lower concentrations in the latter. Current was Cl-dependent and blocked by mucosal diphenylcarboxylic acid, serosal bumetanide, and serosal Ba++. The CFTR inhibitor CFTRinh172 had a marginal effect. Mucus near epithelial cells (inner layer mucus) was not present in the small intestine of any mice. Proximal colon inner mucus layer was thicker in ΔF/ΔF compared with +/ΔF and +/+ mice. Lubiprostone decreased inner mucus layer thickness in both proximal and distal colon of all mice. Furthermore, lubiprostone altered the intestinal microbiome by increasing abundance of Lactobacillus and Alistipes. Conclusions Lubiprostone activates non-CFTR Cl− secretion and alters the colonic inner mucus layer, which is associated with changes in the composition of the enteric microbiome. PMID:23329012

    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.

    Herba Epimdii is a traditional Chinese medicine used to treat osteoporosis. Its main pharmacological ingredients are flavonoids. In previous studies conducted in healthy animals, we showed that epimedium flavonoids could be hydrolyzed into secondary glycosides or aglycon by intestinal flora or enzymes, thereby enhancing their absorption and antiosteoporosis activity. To study the medicine in the pathologic state, epimedium flavonoids were incubated with intestinal mucosa and feces in vitro and intestinal perfusion in situ to explore the differences in absorption and metabolism between sham and osteoporosis rats. For osteoporosis rats, the hydrolysis rates of icariin, epimedin A, epimedin B, and epimedin C incubated with intestinal flora for 1 hour were reduced by 0.19, 0.26, 0.19, and 0.14, respectively, compared with that in sham rats. Hydrolysis rates were reduced by 0.21, 0.24, 0.08, and 0.31 for icariin, epimedin A, epimedin B, and epimedin C incubated with duodenal enzymes for 1 hour and by 0.13, 0.09, 0.07, and 0.47 for icariin, epimedin A, epimedin B, and epimedin C incubated with jejunum enzymes, respectively, compared with the sham group. In addition, the apparent permeability coefficient and elimination percentage of the four epimedium flavonoids in the duodenum, jejunum, ileum, and colon decreased by 29%-44%, 32%-50%, 40%-56%, and 27%-53% compared with that in sham rats, respectively. The main metabolites of the four epimedium flavonoids were the same for the two groups after intestinal perfusion, or flora and enzyme incubation. In conclusion, the amount and activity of intestinal flora and enzymes changed in ovariectomized rats, which affected the intestinal absorption and hydrolysis of epimedium flavonoids whose structures contain 7-glucose.

    Background Patients with traumatic brain injury (TBI) often suffer from gastrointestinal dysfunction including intolerance to enteral feedings. However, it is unclear how TBI affects small intestinal contractile activity. The purpose of this study was to determine if TBI affects intestinal smooth muscle function. Methods Sprague–Dawley rats were subjected to controlled cortical impact injury (TBI). Sham animals underwent a similar surgery but no injury (SHAM). Animals were sacrificed 1, 3, and 7 days after TBI and intestinal smooth muscle tissue was collected for measurement of contractile activity and transit, NF-kB activity, and cytokine levels. Brains were collected after sacrifice to determine volume loss due to injury. Key Results Contractile activity decreased significantly in ileum, but not jejunum, in the TBI group 7 days after injury compared with SHAM. Brain volume loss increased significantly 7 days after injury compared with 3 days and correlated significantly with the contractile activity 1 day after injury. In the intestinal smooth muscle, NF-kB activity increased significantly in the TBI group 3 and 7 days after injury vs SHAM. Wet to dry weight ratio, indicating edema, also increased significantly in the TBI group. Interleukin- 1α, -1β, and -17 increased significantly in the TBI group compared with SHAM. Conclusions & Inferences Traumatic brain injury causes a delayed but significant decrease in intestinal contractile activity in the ileum leading to delayed transit. The decreased intestinal contractile activity is attributed to secondary inflammatory injury as evidenced by increased NF-kB activity, increased edema, and increased inflammatory cytokines in the intestinal smooth muscle.

    Pseudomyxoma peritonei (PMP) is a rare condition complicated by intra-abdominal spread that can cause multilevel gastrointestinal (GI) obstruction. Parenteral nutrition (PN) use in the context of palliative care and malignancy remains controversial. We describe the use of palliative PN in three patients with progressive PMP causing multilevel GI obstruction and intestinal failure. All patients received > 90 days of PN. PN was safe in this cohort of patients. However, patient selection and the timing of intervention are important factors when considering the initiation of PN. PMID:26105107

    1997-01-01

    Intestinal Transplantation used to be an utopia in Medicine, and this was mainly due to the factor that the surgical technique was not the best at the beginning. When this was perfectioned, the next obstacle for the adequate progress of this surgery was the limited availability of anti-rejection drugs due to the fact that Ciclosporine has been and still is a drug of relative effectiveness. With the discovery of new anti-rejection drugs and with a best knowledge of the concomitant liver transplantation roll on the prognosis of these patients, it was possible to get in this decade, specifically in the last 2 years, extraordinary results; for example, from 170 pacients who underwent intestinal transplantation around the world, more than half were done by the University of Pittsburg. This university reported a survival of 62%. But, this percentage has been improved even more, the University of Miami reported a survival of 70% through the use of corticoides and two powerful anti-rejection drugs: FK-506 and Mycophelate.

    2016-01-01

    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

    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.

    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

    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. PMID:26068465

    Peripheral airway dysfunction, inhomogeneous ventilation distribution, gas trapping, and impaired pulmonary gas exchange are variably present in all stages of chronic obstructive pulmonary disease (COPD). This article provides a cogent physiologic explanation for the relentless progression of activity-related dyspnea and exercise intolerance that all too commonly characterizes COPD. The spectrum of physiologic derangements that exist in smokers with mild airway obstruction and a history compatible with COPD is examined. Also explored are the perceptual and physiologic consequences of progressive erosion of the resting inspiratory capacity. Finally, emerging information on the role of cardiocirculatory impairment in contributing to exercise intolerance in patients with varying degrees of airway obstruction is reviewed. PMID:24507837

    Obstructive jaundice as an initial manifestation of uterine cancer is extremely rare. We present a case of a 72-year-old female who presented with obstructive jaundice, supposedly for pancreatic cancer. After detailed diagnostic investigation, the cause of the jaundice was attributed to a metastatic compression of the common bile duct, from the primary neoplasm of the uterus. This case highlights the importance of including uterine cancer in the differential diagnosis of woman presenting with obstructive jaundice, even though it is very rare. PMID:27462179

    The authors present the case of an 84 year-old woman with chronic constipation who suddenly developed acute obstruction of the lower oesophagus on taking a tablespoonful of mucilage without water. The obstruction was relieved by fiber endoscopy. There was no other previous lesion which might explain this complication. The patient was seen again later in good general health. The authors recall the clinical and radiological signs of acute obstruction of the oesophagus and discuss the physiopathology. They propose treating them exclusively by oesophageal fiber endoscopy.

    Ureteropelvic junction obstruction due to intrinsic causes is often diagnosed antenatally during routine ultrasonography. Cases of extrinsic obstruction often present later and symptomatically, during childhood. We describe the rare case of an 8-year-old boy with a 2-day history of severe left flank pain, no fevers, and Society of Fetal Urology grade 3 hydronephrosis on ultrasonography. Laparoscopic dismembered pyeloplasty revealed a left ureteropelvic junction obstruction secondary to a large fibroepithelial polyp in the proximal ureter with a concomitant anterior crossing vein. We also provide a focused review of the pertinent published literature. PMID:26199155

    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.

    Background Intracranial haemorrhage accounts for 30–60 % of all stroke admissions into a hospital, with hypertension being the main risk factor. Presence of intraventricular haematoma is considered a poor prognostic factor due to the resultant obstruction to CSF and the mass effect following the presence of blood resulting in raised intracranial pressure and hydrocephalus. We report the results following endoscopic decompression of obstructive hydrocephalus and evacuation of haematoma in patients with hypertensive intraventricular haemorrhage. Methods During a two year period, 25 patients diagnosed as having an intraventricular haemorrhage with obstructive hydrocephalus secondary to hypertension were included in this study. All patients underwent endoscopic evacuation of the haematoma under general anaesthesia. Post operative evaluation was done by CT scan and Glasgow outcome scale. Results Of the 25 patients, thalamic haemorrhage was observed in 12 (48%) patients, while, 11 (44%) had a putaminal haematoma. Nine (36%) patients had a GCS of 8 or less pre-operatively. Resolution of hydrocephalus following endoscopic evacuation was observed in 24 (96%) patients. No complications directly related to the surgical technique were encountered in our study. At six months follow-up, a mortality rate of 6.3% and 55.5% was observed in patients with a pre-operative GCS of ≥ 9 and ≤ 8 respectively. Thirteen of the 16 (81.3%) patients with a pre-operative GCS ≥ 9 had good recovery. Conclusion Endoscopic technique offers encouraging results in relieving hydrocephalus in hypertensive intraventricular haemorrhage. Final outcome is better in patient with a pre-operative GCS of >9. Future improvements in instrumentation and surgical techniques, with careful case selection may help improve outcome in these patients. PMID:17204141

    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. PMID:16041609

    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. PMID:26832999

    Nutrient absorption is the basic function that drives mammalian intestinal biology. To facilitate nutrient uptake, the host’s epithelial barrier is composed of a single layer of cells. This constraint is problematic, as a design of this type can be easily disrupted. The solution during the course of evolution was to add numerous host defense mechanisms that can help prevent local and systemic infection. These mechanisms include specialized epithelial cells that produce a physiochemical barrier overlying the cellular barrier, robust and organized adaptive and innate immune cells, and the ability to mount an inflammatory response that is commensurate with a specific threat level. The autophagy pathway is a critical cellular process that strongly influences all these functions. Therefore, a fundamental understanding of the components of this pathway and their influence on inflammation, immunity, and barrier function will facilitate our understanding of homeostasis in the gastrointestinal tract.

    The aim of the study was to examine the effect of the seminal tract obstruction of different degree and duration on the morphological and functional condition of testicular tissue. The study was conducted in 50 male Wistar rats. Three experimental models of seminiferous tract obstruction were set up: obstruction of the proximal part of the ductus deferens, obstruction of the distal part of the ductus deferens and obstruction of at the epididymis level. Morphological evaluation of testicular tissue was performed at 3 and 6 months after the obstruction. It was found that obstruction at the epididymis level caused the most severe impairment of spermatogenesis. PMID:26665771

    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. PMID:24298509

    Short bowel syndrome (SBS) results from the loss of a highly specialized organ, the small intestine. SBS and its current treatments are associated with high morbidity and mortality. Production of tissue-engineered small intestine (TESI) from the patient's own cells could restore normal intestinal function via autologous transplantation. Improved understanding of intestinal stem cells and their niche have been coupled with advances in tissue engineering techniques. Originally described by Vacanti et al of Massachusetts General Hospital, TESI has been produced by in vivo implantation of organoid units. Organoid units are multicellular clusters of epithelium and mesenchyme that may be harvested from native intestine. These clusters are loaded onto a scaffold and implanted into the host omentum. The scaffold provides physical support that permits angiogenesis and vasculogenesis of the developing tissue. After a period of 4 weeks, histologic analyses confirm the similarity of TESI to native intestine. TESI contains a differentiated epithelium, mesenchyme, blood vessels, muscle, and nerve components. To date, similar experiments have proved successful in rat, mouse, and pig models. Additional experiments have shown clinical improvement and rescue of SBS rats after implantation of TESI. In comparison with the group that underwent massive enterectomy alone, rats that had surgical anastomosis of TESI to their shortened intestine showed improvement in postoperative weight gain and serum B12 values. Recently, organoid units have been harvested from human intestinal samples and successfully grown into TESI by using an immunodeficient mouse host. Current TESI production yields approximately 3 times the number of cells initially implanted, but improvements in the scaffold and blood supply are being developed in efforts to increase TESI size. Exciting new techniques in stem cell biology and directed cellular differentiation may generate additional sources of autologous intestinal

    Infertility is a distressing condition but extenuating circumstances sometimes make the choice of treatment seem paradoxical. Here is discussed a challenging case of a 30-year-old woman with no living child and secondary infertility who presented with a large abdominal mass and severe abdominal pain, sequelae of previous obstructed labour. There was complex management dilemma. She was young, had no living child, had undergone vesicovaginal fistula (VVF) repair and vaginoplasty yet was wanting fertility; however she was distressed with the abdominal pain and desired a complete cure. Both she and her spouse were counselled about the high possibility of failure if repeat attempt at vaginoplasty was made, and possible damage to the VVF repair. Finally, decision of exploratory laparotomy with total abdominal hysterectomy was taken after counselling the couple about adoption as an option for childbearing. PMID:25935952

    The objective of our study was to evaluate bladder outlet obstruction number (BOON) in order to predict infravesical obstruction in patients with benign prostatic enlargement (BPE). Two hundred patients with proven BPE from daily urological practice at the Urology Department of the Sarajevo University Clinical Centre were covered by a prospective study in period 2009-2011. All patients completed International Prostatic Symptom Score, their mean voided volume urine was determined from frequency-volume chart and their prostate volume was determined by transabdominal ultrasound. Subsequently, the patients had free uroflowmetry and they underwent complete urodynamic studies. BOON was calculated using the formula: prostate volume (cc)-3 x Qmax (ml/s)-0.2 x mean voided volume (ml). A satisfactory area under the curve (AUC) was obtained for the prediction of obstruction according to bladder outlet obstruction index, Schaefer obstruction class nomogram and group specific urethral resistance factor , with AUC of 0.83 (p<0.001). Following the comparison of different cut-off values of BOON according to the obstruction, the BOON >-20 has been found to be the most accurate obstruction indicator (sensitivity 76.5% and specificity 68.2%), with posttest probability of 77%. The BOON may be used in daily urological practice as a valid, non-invasive indicator of infravesical obstruction in patients with BPE, with a possibility of correct classification of obstruction in approximately 75% of the cases. Transabdominal ultrasound has shown to be applicable to the BOON formula in determining prostate volume. PMID:22938540

    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. PMID:12974175

    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.

    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. PMID:26727661

    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.

    A variety of nematodes occur in dogs and cats. Several nematode species inhabit the small and large intestines. Important species that live in the small intestine are roundworms of the genus Toxocara (T canis, T cati) and Toxascaris (ie, T leonina), and hookworms of the genus Ancylostoma (A caninum, A braziliense, A tubaeforme) or Uncinaria (U stenocephala). Parasites of the large intestine are nematodes of the genus Trichuris (ie, whipworms, T vulpis). After a comprehensive description of their life cycle and biology, which are indispensable for understanding and justifying their control, current recommendations for nematode control are presented and discussed thereafter.

    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. PMID:25199187

    This case report describes the diagnosis of secondary malignant lymphoedema in two dogs that had undergone a mastectomy. A remarkable severe oedematous lesion associated with lameness in the right hindlimb was observed in both cases. Diagnostic imaging examinations, including direct pedal lymphangiography (case 1) and lymphoscintigraphy (case 2), showed obstruction of lymph flow in the lymphatics of the right hindlimbs. Although the recommended medical management and physiotherapy had been applied to resolve the problems, oedema did not improve in the damaged region in both cases. Results of histopathological examinations suggested that the cause of the obstructed lymph flow was neoplastic cells in the lymphatics of the right hindlimb in both dogs. PMID:17490446

    Candida albicans is a fungus that can cause opportunistic urinary tract infections in immunocompromised patients. Disseminated fungaemia secondary to Candida albicans is associated with considerable mortality and therefore merits aggressive treatment. Diagnostic investigations for urosepsis and disseminated fungaemaia secondary to Candida albicans include positive urine and blood cultures. Herein, we describe an extremely unusual case of disseminated fungaemia associated with an obstructive fungus-ball in the distal ureter of an immunosuppressed patient. We also describe a novel application of an established endourological technique for managing this clinical scenario and discuss appropriate perioperative management strategies. PMID:23766839

    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

    Two infants with nonfunctioning antenatally detected multicystic dysplastic kidneys developed acute renal failure in conjunction with pelviureteric obstruction of the contralateral kidney at 9 and 14 months of age, respectively. The initial postnatal ultrasounds had shown mild pelvic dilatation in both cases. Clinicians need to be aware of the possibility of late obstruction. We suggest that it is good practice to review patients with antenatally detected urinary tract abnormalities and equivocal investigations at joint nephrouroradiology meetings. PMID:15599563

  3. Airflow analysis in mechanically ventilated obstructed rooms

    Local and mean air velocities and standard deviations were measured in realistic rooms. Obstructions represented occupants and equipment in the rooms, internal heat loads varied and supply air temperature differed from room averages. Experimental setups differed for the isothermal and nonisothermal tests. Room dimensions for isothermal tests were 2.44 m high by 4.88 x 4.88 m. Ten different obstruction ratios using three different inlet types were analyzed. Obstructions covered 0 to 30% floor area and from 0 to 75% of room height. Air was supplied at ventilation rates ranging between 0.8 and 1.1 m 3/s. Room dimensions for the nonisothermal tests were 2.44 m high by 3.66 x 7.32 m. Obstruction differences between solid versus open partitions for farrowing crates were investigated for three commercially available inlets using two ventilation loads. Ventilation rates were 0.11 to 1.18 m 3/s, simulating cold and warm weather ventilation conditions, respectively. Based on these data and theoretical calculations, a kinetic energy model that predicts average room air velocity and energy level was developed as a practical room air flow design and analysis tool. It was recommended that designers interested in using CFD as a tool should use a three dimensional laminar model for acceptable qualitative flow results. It was concluded that for typical room flowrates and inlet types the room air distribution system is obstruction ratio independent. Local velocities and standard deviations varied with each obstruction setup and inlet combination. However, average air velocities and turbulence intensities were not influenced by obstruction setups or inlet configurations. The decay rate of mean velocity kinetic energy in the bulk flow region was independent of obstructions and inlets. Room average kinetic energy was a function of the supplied kinetic energy within the supply jet plus internal kinetic energy resulting from internal heat load (convective energy).

    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.

    Maldevelopment of the collecting system resulting in urinary tract obstruction (UTO) is the leading identifiable cause of CKD in children. Specific etiologies are unknown; most cases are suspected by discovering hydronephrosis on prenatal ultrasonography. Congenital UTO can reduce nephron number and cause bladder dysfunction, which contribute to ongoing injury. Severe UTO can impair kidney growth in utero, and animal models of unilateral ureteral obstruction show that ischemia and oxidative stress cause proximal tubular cell death, with later development of interstitial fibrosis. Congenital obstructive nephropathy, therefore, results from combined developmental and obstructive kidney injury. Because of inadequacy of available biomarkers, criteria for surgical correction of upper tract obstruction are poorly established. Lower tract obstruction requires fetal or immediate postnatal intervention, and the rate of progression of CKD is highly variable. New biomarkers based on proteomics and determination of glomerular number by magnetic resonance imaging should improve future care. Angiotensin inhibitors have not been effective in slowing progression, although avoidance of nephrotoxins and timely treatment of hypertension are important. Because congenital UTO begins in fetal life, smooth transfer of care from perinatologist to pediatric and adult urology and nephrology teams should optimize quality of life and ultimate outcomes for these patients.

    Two patients with seriously impaired left ventricular function, abnormal left ventricular conduction on the electrocardiogram, mitral regurgitation, and a very late systolic click are reported. Idiopathic non-obstructive cardiomyopathy seemed to be the cause of the left ventricular dysfunction in both cases. The mitral valve was anatomically normal at the time of operation in one patient, except for dilatation of the annulus, and the mitral regurgitation appeared to be secondary to left ventricular failure. The very late timing of the mitral systolic clicks in these two patients may be related to a large left ventricular end-diastolic volume and impaired left ventricular function, or to an abnormal sequence of excitation of the left ventricle. The timing of the late systolic click in these patients is in contrast to that in patients with mid systolic clicks, hearts of normal size, and little cardiac disability. Images PMID:5470052

    Primary intestinal lymphangiectasia (PIL) is a protein-losing, exsudative gastroenteropathy causing lymphatic obstruction. Diagnosis depends on clinical examination and histological findings. Conservative treatment modalities include a low-fat diet and enteral nutritional therapy in order to reduce enteric protein loss and to improve fat metabolism. Other treatment options consist of administration of antiplasmin or octreotide to lower lymph flow and secretion. We report on a 58-year-old patient who underwent exploratory laparotomy due to a worsening physical status, recurrent chylaskos and leg oedema under conservative dietary therapy. Intraoperative findings showed a typical PIL of the jejunum about 20 cm distal to the Treitz's ligament. Histological examinations confirmed this diagnosis. One year after segmental small bowel resection (105 cm) with end-to-end anastomosis the patient is healthy, free of symptoms, has gained weight and his serum protein level has increased. Intraabdominal ascites and leg oedema have not reoccurred since. PMID:23229460

    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

    Background Obstructive sleep apnea is associated with an increased risk of cardiovascular events; whether treatment with continuous positive airway pressure (CPAP) prevents major cardiovascular events is uncertain. Methods After a 1-week run-in period during which the participants used sham CPAP, we randomly assigned 2717 eligible adults between 45 and 75 years of age who had moderate-to-severe obstructive sleep apnea and coronary or cerebrovascular disease to receive CPAP treatment plus usual care (CPAP group) or usual care alone (usual-care group). The primary composite end point was death from cardiovascular causes, myocardial infarction, stroke, or hospitalization for unstable angina, heart failure, or transient ischemic attack. Secondary end points included other cardiovascular outcomes, health-related quality of life, snoring symptoms, daytime sleepiness, and mood. Results Most of the participants were men who had moderate-to-severe obstructive sleep apnea and minimal sleepiness. In the CPAP group, the mean duration of adherence to CPAP therapy was 3.3 hours per night, and the mean apnea-hypopnea index (the number of apnea or hypopnea events per hour of recording) decreased from 29.0 events per hour at baseline to 3.7 events per hour during follow-up. After a mean follow-up of 3.7 years, a primary end-point event had occurred in 229 participants in the CPAP group (17.0%) and in 207 participants in the usual-care group (15.4%) (hazard ratio with CPAP, 1.10; 95% confidence interval, 0.91 to 1.32; P=0.34). No significant effect on any individual or other composite cardiovascular end point was observed. CPAP significantly reduced snoring and daytime sleepiness and improved health-related quality of life and mood. Conclusions Therapy with CPAP plus usual care, as compared with usual care alone, did not prevent cardiovascular events in patients with moderate-to-severe obstructive sleep apnea and established cardiovascular disease.

    This study focused on the localization of transient receptor potential vanilloid type 1 (TRPV1) in the intestines in postoperative adhesion model rats and investigated the underlying mechanism for the anti-adhesion action of daikenchuto (DKT), especially in relation to TRPV1. Postoperative intestinal adhesion was induced by sprinkling talc in the small intestine. The expression of TRPV1 mRNA was examined by in situ hybridization and real-time RT-PCR. The effects of DKT and its major ingredient, hydroxy sanshool, with or without ruthenium red, a TRP-channel antagonist, on talc-induced intestinal adhesions were evaluated. The level of TRPV1 mRNA was higher in the adhesion regions of talc-treated rats than in normal small intestine of sham-operated rats. Localization of TRPV1 mRNA expression was identified in the submucosal plexus of both sham-operated and talc-treated rats; and in talc-treated rats, it was observed also in the myenteric plexus and regions of adhesion. Capsaicin, DKT, and hydroxy sanshool significantly prevented formation of intestinal adhesions. The effects of DKT and hydroxy sanshool were abrogated by subcutaneous injection of ruthenium red. These results suggest that pharmacological modulation of TRPV1 might be a possible therapeutic option in postoperative intestinal adhesion, which might be relevant to the prevention of postoperative adhesive obstruction by DKT.

    Partial bowel obstruction is a serious complication of ascariasis infestation generally treated with mineral oil. This prospective study aimed to evaluate the efficacy of multiple bronchoalveolar lavages (BAL) as a therapeutic strategy for reducing lung inflammation of lipoid pneumonia associated with ascariasis. The study included five children (mean age 25 months) with partial small-bowel obstruction by Ascaris lumbricoides, who underwent diagnostic bronchoalveolar lavage for assessment of refractory pneumonia. Routine biochemical, microbiological and cytological analysis were carried out in the BAL. Protein, lactate dehydrogenase and tumor necrosis factor-alpha (TNF-α) cytokine levels were determined in the serum before and after treatment. At admission, children consistently had respiratory symptoms, altered hematological function, increased immunoglobulin E serum level and peripheral blood eosinophilia. Chest tomography showed consolidation with air bronchogram (4/4), ground-glass infiltration (3/4) and decreased attenuation in the consolidation areas (2/4). Presence of marked pleocytosis with Sudan positive foamy alveolar macrophages, high protein and lactate dehydrogenase levels in the BAL indicated presence of mixed alveolitis. One child with extensive consolidation and air bronchogram in both lungs died before treatment. Multiple bronchoalveolar lavages efficiently removed alveolar oil deposits, restored BAL cellularity, improved clinical symptoms, radiological parameters and further reduced inflammatory reaction evidenced by marked decrease of the inflammatory cytokine, TNF-α. This study presents a therapeutic strategy for management of lung complications caused by mineral oil administration to treat intestinal bowel obstruction associated with ascariasis. PMID:20026557

    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.

    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.
