To investigate the possibility that an abnormality of gastric emptying exists in duodenal ulcer and to determine if such an abnormality persists after ulcer healing, scintigraphic gastric emptying measurements were undertaken in 16 duodenal ulcer patients before, during, and after therapy with cimetidine; in 12 patients with pernicious anemia, and in 12 control subjects. No difference was detected in the rate or pattern of gastric emptying in duodenal ulcer patients before and after ulcer healing with cimetidine compared with controls, but emptying of the solid component of the test meal was more rapid during treatment with the drug. Comparison of emptying patterns obtained in duodenal ulcer subjects during and after cimetidine treatment with those obtained in pernicious anemia patients and controls revealed a similar relationship that was characterized by a tendency for reduction in the normal differentiation between the emptying of solid and liquid from the stomach. The similarity in emptying patterns in these groups of subjects suggests that gastric emptying of solids may be influenced by changes in the volume of gastric secretion. The failure to detect an abnormality of gastric emptying in duodenal ulcer subjects before and after ulcer healing calls into question the widespread belief that abnormally rapid gastric emptying is a feature with pathogenetic significance in duodenal ulcer disease

Full Text Available Congenital duodenal atresia complicated by gastric perforation (GP is a very rare and a very mortal condition. Only three newborns could be cured in the reported 13 cases. We report a successfully treated newborn with this complicated disease. A 2-day-old male was hospitalized with prediagnosis of duodenal obstruction. Twelve hours later, significant abdominal distention occurred promptly. At laparotomy, GP and preampullary duodenal atresia were detected. Gastrorrhaphy and duodenoduodenostomy were performed in the same operation. The patient was discharged on the 15th postoperative day. This complicated disease can be treated by early diagnosis and surgical intervention. We choose one-stage operation because of the clean peritoneal cavity. However, generalized peritonitis may require two-stage operation in delayed cases.

Full Text Available 【Abstract】Duodenal trauma is uncommon but nowadays seen more and more frequently due to the increased automobile accidents and violent events. The management of duodenal trauma can be complicated, especially when massive injury to the pancreatic-duodenal-biliary complex occurs simultaneously. Even the patients receive surgeries in time, multiple postoperative complications and high mortality are common. To know and manage duodenal trauma better, we searched the recent related literature in PubMed by the keywords of duodenal trauma, therapy, diagnosis and abdomen. It shows that because the diagnosis and management are complicated and the mortality is high, duodenal trauma should be treated in time and tactfully. And application of new technology can help improve the management. In this review, we discussed the incidence, diagnosis, management, and complications as well as mortality of duodenal trauma.

Full Text Available Celiac disease is usually diagnosed by demonstrating gluten enteropathy in small bowel biopsy. Celiac specific antibodies are used as an initial screening test. The goal of this study is to test the relationship of the anti-tTG titer and severity of histological changes in Jordanian children with celiac disease. Method. The medical records of 81 children who had elevated anti-tTG titer and had duodenal biopsies available were retrospectively reviewed. Result. Assessing the association of anti-tTG titer with duodenal histopathological changes, 94% of those with high anti-tTG titer (≥180 U/mL had histological evidence of celiac disease. There was statistically significant positive association between high anti-tTG titer and Marsh grading as 82% of patients with Marsh III had high anti-tTG titer (Chi2 18.5; P value 0.00; Odds Ratio 8.5. The fraction of patients with Marsh III who were correctly identified as positive by anti-tTG titer ≥ 180 U/mL was high (sensitivity = 81.6. Moreover, the fraction of patients with anti-tTG titer ≥ 180 U/mL who had Marsh III was also high (positive predictive value = 78.4. Conclusion. Anti-tTG titer ≥ 180 U/mL had significant positive association with Marsh III histopathological changes of celiac disease.

Villous atrophy and increased numbers of intraepithelial T cells in duodenal biopsies represent a hallmark of coeliac disease. In the present study, an attempt has been made to define whether cytotoxic cell subsets are activated in situ in the affected mucosa of susceptible individuals early after ingestion of a gluten-containing diet. Duodenal biopsies from 11 patients with coeliac disease who repeatedly underwent endoscopic biopsy after ingestion of individually dosed amounts of gluten were used for immunohistochemistry and in situ hybridization. To identify the cell subsets expressing perforin mRNA and protein, in situ hybridization and FACS analyses were performed on cells isolated from fresh biopsies. Compared with normal mucosa, the number of intraepithelial lymphocytes containing perforin mRNA and protein increased significantly in tissue samples showing moderate or florid coeliac disease and closely paralleled the severity of morphological alteration, whereas the frequency of perforin-expressing lamina propria lymphocytes increased only moderately. Cells isolated from florid biopsies that expressed perforin mRNA and protein were preferentially T-cell receptor (TCR) alphabeta T cells. The increase in both the absolute number and the percentage of lymphocytes expressing perforin mRNA indicates in situ activation of lymphocytes within the epithelial compartment in florid coeliac disease upon ingestion of a gluten-containing diet in patients predisposed to coeliac disease.

The purpose of this study was to describe the clinical and gross pathological findings, treatment, and outcome in three dogs receiving deracoxib that developed proximal duodenal perforation and subsequent septic peritonitis. Clinical findings were acute vomiting and anorexia following initiation of deracoxib therapy. Deracoxib dosages ranged from 2 to 3 mg/kg per os q 24 hours. In each dog, exploratory laparotomy revealed duodenal perforations approximately 1 cm orad to the major duodenal papilla. Two out of three dogs survived following exploratory laparotomy. Two of three dogs in the present case series received the approved deracoxib dosage. Dogs receiving deracoxib, even at labeled dosages, should be monitored judiciously for signs of gastrointestinal disease.

To evaluate the effectiveness and the safety of the spa and resort-based health-promoting treatment of the vehicle drivers (VD) presenting with duodenal ulcer disease. A total of 67 men suffering from duodenal ulcer disease (DUD) were allocated to two groups. The patients of group 1 (n = 35) were given the courses of balneotherapy that included bromine-iodine mineral baths with a temperature of 36-37 degrees C (8-9 procedures 10-15 min long each every second day) in combination with 8-9 peloid applications to the epigastric region (temperature 38-40 degrees C for 10-15 min every second day). The patients of group 2 (n = 32) were given the similar courses of therapy that included nitric thermal mineral baths with a temperature of 36-37 degrees C (8-9 procedures 10-15 min long each every second day) in combination with 8-9 peloid applications to the epigastric region (38-40 degrees C for 10-15 min every second day). The effectiveness and safety of these balenotherapeutic procedures for the treatment of duodenal ulcer disease in the subjects of the study and control (n = 47) groups were evaluated based on the results of the routine clinical and endoscopic examination, psychological and psychophysiological tests, and the comparative analysis of medical aid appeal-ability and disability cases during twelve months. Dynamics of clinical and instrumental characteristics (subjective, objective, clinical, endoscopic, psychophysiological) suggested the improvement of the health status in 88.6% and 84.4% of the drivers with duodenum ulcer in the two study groups respectively. Some of the patients comprising group 1 showed significant negative dynamics of the operative reaction system while the patients of group 2 demonstrated the marked improvement of the professionally significant functions and properties (PSF&P). The comparative analysis of medical aid appealability, disability cases, frequency of relapses and complications revealed the favorable clinical course of duodenal

History of Helicobacter pylori, duodenal ulcer, gastric ulcer and gastric cancer.

Science.gov (United States)

Graham, David Y

2014-05-14

Helicobacter pylori (H. pylori) infection underlies gastric ulcer disease, gastric cancer and duodenal ulcer disease. The disease expression reflects the pattern and extent of gastritis/gastric atrophy (i.e., duodenal ulcer with non-atrophic and gastric ulcer and gastric cancer with atrophic gastritis). Gastric and duodenal ulcers and gastric cancer have been known for thousands of years. Ulcers are generally non-fatal and until the 20th century were difficult to diagnose. However, the presence and pattern of gastritis in past civilizations can be deduced based on the diseases present. It has been suggested that gastric ulcer and duodenal ulcer both arose or became more frequent in Europe in the 19th century. Here, we show that gastric cancer and gastric ulcer were present throughout the 17th to 19th centuries consistent with atrophic gastritis being the predominant pattern, as it proved to be when it could be examined directly in the late 19th century. The environment before the 20th century favored acquisition of H. pylori infection and atrophic gastritis (e.g., poor sanitation and standards of living, seasonal diets poor in fresh fruits and vegetables, especially in winter, vitamin deficiencies, and frequent febrile infections in childhood). The latter part of the 19th century saw improvements in standards of living, sanitation, and diets with a corresponding decrease in rate of development of atrophic gastritis allowing duodenal ulcers to become more prominent. In the early 20th century physician's believed they could diagnose ulcers clinically and that the diagnosis required hospitalization for "surgical disease" or for "Sippy" diets. We show that while H. pylori remained common and virulent in Europe and the United States, environmental changes resulted in changes of the pattern of gastritis producing a change in the manifestations of H. pylori infections and subsequently to a rapid decline in transmission and a rapid decline in all H. pylori-related diseases.

Gurteyik, E.

2003-01-01

Objective: To evaluate changes in the emergency surgery of the duodenal ulcer. Subjects and Methods: Hospital records of 523 surgically treated patients, with duodenal ulcer perforation, during the period of 25 years 91975-1999) in the same surgical department, was retrospectively analysed. Changing aspects of emergency surgery of peptic ulcer disease, in the recent period, were determined in respect to number of operations per year and in the choice of operative methods. Results: The average number of patients and emergency operations per year was 21. No significant change was observed during the study period. Elective operations gradually decreased in the last ten years, and none was performed in the last 4 years. On the other hand, 226 emergency interventions for duodenal ulcer perforation were performed in the last ten years and 84 interventions in the last 4 years. Definitive anti-ulcer surgery was performed in 42% of patients between 1985 and 1994. Simple closure of the perforation plus treatment with proton pump inhibitors and with anti-Helicobacter pylori medication was the method in 80% during the last year. Conclusion: Emergency surgery for perforated duodenal ulcer preserves its steady rate despite disappearance of elective operations after tremendous progress in medical control of peptic ulcer disease. There is an obvious return from definitive anti-ulcer surgery to simple closure of the perforation followed by antisecretory and antibacterial medications in the recent years. (author)

Congenital duodenal obstruction (CDO) is common and usually easy to diagnose cause of intestinal obstruction in the newborn, except when the cause of the obstruction is duodenal diaphragm. We describe our experience with eight children who had intrinsic duodenal obstruction secondary to a duodenal diaphragm. The medical record of 22 children with the diagnosis of congenital intrinsic duodenal were reviewed for age, sex, gestation, birth weight, clinical features, associated anomalies, method of diagnosis, treatment and outcome. Operative findings and procedures were obtained from the operative notes. Eight of 22 children (36.4%) had congenital duodenal diaphragm (CDD). In all children, the diagnosis was made from the plain abdominal X-ray, which showed the classic double-bubble appearence, and barium meal, which showed duodenal obstruction. Four patients had associated anomalies, including two with Down's syndrome intraoperatively, five patients were found to have duodenal diaphragm with a central hole, while the other three had complete duodenal diaphragms. Postoperatively, all patients did well. Six required total parenteral nutrition. The 100% survival rate among these children is comparable to that in Western countries, and can be attributed to the lack of major associated abnormalities, good perioperative management, and the availability of total parenteral nutrition.

An ectopic opening of the common bile duct into the duodenal bulb is a very rare congenital malformation of the bile duct, which may cause a recurrent duodenal ulcer or biliary diseases including choledocholithiasis or cholangitis. ERCP plays major role in the diagnosis of this biliary malformation. We report a case of an ectopic opening of the common bile duct into the duodenal bulb, which was detected on the upper gastrointestinal series.

To assess fluctuations in quality of life (QoL) and motor performance in patients with advanced Parkinson disease (PD) treated with continuous daytime duodenal levodopa/carbidopa infusion or conventional therapy. Of 18 patients completing a 6-week trial (DIREQT), 12 were followed for up to 6 months and assessed using electronic diaries and the PD Questionnaire-39 (PDQ-39). During the trial and follow-up, major diurnal fluctuations were observed, especially for hyperkinesia, 'off' time, ability to walk and depression. Duodenal infusion was associated with significantly more favourable outcomes compared with conventional treatment for satisfaction with overall functioning, 'off' time and ability to walk, with improved outcomes with PDQ-39. Relative to conventional treatment, infusion therapy may stabilize and significantly improve motor function and patient's QoL. The potential for daily fluctuation in PD symptoms means single measures of treatment effectiveness can result in bias in effect estimates and hence repeated measures are recommended.

Full Text Available Duodenal varices (DV are rare in patients with portal hypertension secondary to liver disease. Their tendency to bleed is less common than in gastroesophageal varices, but can sometimes produce a life-threatening bleed. They are often difficult to diagnose and treat. We present a case of a 35-year-old man with parenchymal liver disease admitted with complaints of hematemesis and melena. Upper gastrointestinal endoscopy was performed and a duodenal varix, with stigmata of a recent bleed, was noted in the second part of the duodenum. Five milliliters of N-butyl-2-cyanoacrylate glue was injected into the varix leading to obliteration. A follow-up study with an endoscopic ultrasound and repeat endoscopy showed near total obturation of the varix and success of the therapy. This report concludes that glue injection can effectively be used as a first-line treatment for bleeding duodenal varices.

Impairment of bone mineral density (BMD) is frequent in celiac disease (CD) patients on a gluten-free diet (GFD). The normalization of intestinal mucosa is still difficult to predict. We aim to investigate the relationship between BMD and duodenal mucosa healing (DMH) in CD patients on a GFD. Sixty-four consecutive CD patients on a GFD were recruited. After a median period of a 6-year GFD (range 2-33 years), patients underwent repeat duodenal biopsy and dual-energy X-ray absorptiometry (DXA) scan. Twenty-four patients (38%) displayed normal and 40 (62%) low BMD, 47 (73%) DMH, and 17 (27%) duodenal mucosa lesions. All patients but one with normal BMD (23 of 24, 96%) showed DMH, while, among those with low BMD, 24 (60%) did and 16 (40%) did not. At multivariate analysis, being older (odds ratio (OR) 1.1, 95% confidence interval (CI) 1.03-1.18) and having diagnosis at an older age (OR 1.09, 95% CI 1.03-1.16) were associated with low BMD; in turn, having normal BMD was the only variable independently associated with DMH (OR 17.5, 95% CI 1.6-192). In older CD patients and with late onset disease, BMD recovery is not guaranteed, despite a GFD. A normal DXA scan identified CD patients with DMH; thus, it is a potential tool in planning endoscopic resampling.

Treatment of refractory celiac disease type II (RCD II) and preventing the development of an enteropathy associated T-cell lymphoma in these patients is still difficult. In this case report, we describe a patient with RCD II who received fecal microbiota transfer as treatment for a recurrent Clostridium difficile infection, and remarkably showed a full recovery of duodenal villi and disappearance of celiac symptoms. This case suggests that altering the gut microbiota may hold promise in improving the clinical and histological consequences of celiac disease and/or RCD II.

Intestinal lymphangiectasia, characterized by dilatation of intestinal lacteals, is rare. The major treatment for primary intestinal lymphangiectasia is dietary modification. Surgery to relieve symptoms and to clarify the etiology should be considered when medical treatment failed. This article reports a 49-year-old woman of solitary duodenal lymphangiectasia, who presented with epigastralgia and anemia. Her symptoms persisted with medical treatment. Surgery was finally performed to relieve the symptoms and to exclude the existence of underlying etiologies, with satisfactory effect. In conclusion, duodenal lymphangiectasia can present clinically as epigastralgia and chronic blood loss. Surgical resection may be resorted to relieve pain, control bleeding, and exclude underlying diseases in some patients. PMID:14669360

We report a case of lipoma in the antrum of the stomach which prolapsed into the duodenal bulb and caused a duodenal ulcer, which was speculated to have been induced by the friction of its tip against the duodenal mucosa. Although the duodenal ulcer healed after the administration of a proton pump inhibitor, the symptoms of epigastric discomfort continued, which was suggested to be due to the prolapse. Therefore, a laparoscopic operation was conducted. The incidence of lipoma of the stomach is rare, and cases of its prolapse into the duodenum are few. Furthermore, it is extremely rare for it to cause a duodenal ulcer. Because these features made this case clinically interesting, we report it here.

Abnormal duodenal loop demonstrated by X-ray

The occurrence of dyspeptic symptoms has previously been correlated with the shape of the duodenal loop in patients with X-ray-negative dyspepsia. An abnormal duodenal loop was associated with a significantly higher incidence of symtoms provoked by meals, vomiting, regurgitations, heartburn, and the irritable bowel syndrome. 89% of these patients (26 patients with a normal duodenal loop and 39 patients with abnormal duodenal loop) were available for a 5-year follow-up study of symptomatic outcome. The incidence of symptoms provoked by meals was still significantly higher in patients with an abnormal duodenal loop, and there was also a significant difference concerning symptomatic outcome. Approximately 75% of the patients with a normal duodenal loop had improved, and 25% had unchanged clinical conditions. Approximately 50% of the patients with an abnormal duodenal loop had improved, and 50% had an unchanged or even deteriorated clinical condition

This study was conducted to evaluate an adapter-modified Ussing chamber for assessment of transport physiology in endoscopically obtained duodenal biopsies from healthy cats and dogs, as well as dogs with chronic enteropathies. 17 duodenal biopsies from five cats and 51 duodenal biopsies from 13 dogs were obtained. Samples were transferred into an adapter-modified Ussing chamber and sequentially exposed to various absorbagogues and secretagogues. Overall, 78.6% of duodenal samples obtained from cats responded to at least one compound. In duodenal biopsies obtained from dogs, the rate of overall response ranged from 87.5% (healthy individuals; n = 8), to 63.6% (animals exhibiting clinical signs of gastrointestinal disease and histopathological unremarkable duodenum; n = 15), and 32.1% (animals exhibiting clinical signs of gastrointestinal diseases and moderate to severe histopathological lesions; n = 28). Detailed information regarding the magnitude and duration of the response are provided. The adapter-modified Ussing chamber enables investigation of the absorptive and secretory capacity of endoscopically obtained duodenal biopsies from cats and dogs and has the potential to become a valuable research tool. The response of samples was correlated with histopathological findings. PMID:24378587

Giant duodenal ulcers

Eric Benjamin Newton; Mark R Versland; Thomas E Sepe

2008-01-01

Giant duodenal ulcers (GDUs) are a subset of duodenal ulcers that have historically resulted in greater morbidity than usual duodenal ulcers. Until recently,few cases had been successfully treated with medical therapy. However, the widespread use of endoscopy,the introduction of H-2 receptor blockers and proton pump inhibitors, and the improvement in surgical techniques all have revolutionized the diagnosis,treatment and outcome of this condition. Nevertheless,GDUs are still associated with high rates of morbidity,mortality and complications. Thus, surgical evaluation of a patient with a GDU should remain an integral part of patient care. These giant variants, while usually benign, can frequently harbor malignancy. A careful review of the literature highlights the important differences when comparing GDUs to classical peptic ulcers and why they must be thought of differently than their more common counterpart.

A significant fraction of celiac disease patients suffer from persistent symptoms despite a long-term gluten-free diet (GFD) and normalized small bowel mucosa. The commonly suggested reasons, such as inadvertent gluten-intake or presence of other gastrointestinal disease, do not explain the symptoms in all these patients. Recently, alterations in intestinal microbiota have been associated with autoimmune disorders, including celiac disease. This led us to test a hypothesis that abnormal intestinal microbiota may be associated with persisting gastrointestinal symptoms in treated celiac disease patients. Duodenal microbiota was analyzed in 18 GFD-treated patients suffering from persistent symptoms and 18 treated patients without symptoms by 16S rRNA gene pyrosequencing. The celiac disease patients had been following a strict GFD for several years and had restored small bowel mucosa and negative celiac autoantibodies. Their symptoms on GFD were assessed with Gastrointestinal Symptom Rating Scale. The results of several clustering methods showed that the treated celiac disease patients with persistent symptoms were colonized by different duodenal microbiota in comparison with patients without symptoms. The treated patients with persistent symptoms had a higher relative abundance of Proteobacteria (P=0.04) and a lower abundance of Bacteroidetes (P=0.01) and Firmicutes (P=0.05). Moreover, their microbial richness was reduced. The results indicated intestinal dysbiosis in patients with persistent symptoms even while adhering to a strict GFD. Our findings indicate that dysbiosis of microbiota is associated with persistent gastrointestinal symptoms in treated celiac disease patients and open new possibilities to treat this subgroup of patients.

This pictorial review aims to illustrate the magnetic resonance imaging (MRI) findings and presentation patterns of anatomical variations and various benign and malignant pathologies of the duodenum, including sphincter contraction, major papilla variation, prominent papilla, diverticulum, annular pancreas, duplication cysts, choledochocele, duodenal wall thickening secondary to acute pancreatitis, postbulbar stenosis, celiac disease, fistula, choledochoduodenostomy, external compression, polyps, Peutz-Jeghers syndrome, ampullary carcinoma and adenocarcinoma. MRI is a useful imaging tool for demonstrating duodenal pathology and its anatomic relationships with adjacent organs, which is critical for establishing correct diagnosis and planning appropriate treatment, especially for surgery.

Is Helicobacter pylori Infection the Primary Cause of Duodenal Ulceration or a Secondary Factor? A Review of the Evidence

Full Text Available Helicobacter pylori (H. pylori has a role in the multifactorial etiology of peptic ulcer disease. A link between H. pylori infection and duodenal ulcer disease is now established. Other contributing factors and their interaction with the organism may initiate the ulcerative process. The fact that eradication of H. pylori infection leads to a long-term cure in the majority of duodenal ulcer patients and the fact that the prevalence of infection is higher in ulcer patients than in the normal population are cogent arguments in favor of it being the primary cause of the ulceration. Against this concept there are issues that need explanation such as the reason why only a minority of infected persons develop duodenal ulceration when infection with H. pylori is widespread. There is evidence that H. pylori infection has been prevalent for several centuries, yet duodenal ulceration became common at the beginning of the twentieth century. The prevalence of duodenal ulceration is not higher in countries with a high prevalence of H. pylori infection. This paper debate puts forth the point of view of two groups of workers in this field whether H. pylori infection is the primary cause of duodenal ulcer disease or a secondary factor.

To investigate the roles of the neuropeptides vasoactive intestinal peptide (VIP), substance P (SP), and calcitonin gene-related peptide (CGRP) in chronic gastritis and duodenitis in children. Biopsy samples from the gastric and duodenal mucosa of 52 patients and 30 control subjects were obtained. Samples were taken for pathological examination, immunohistochemical staining, enzyme activity measurements and quantitative measurements of tissue peptide levels. We observed differential effects of the disease on peptide levels, which were somewhat different from previously reported changes in chronic gastritis in adults. Specifically, SP was increased and CGRP and VIP were decreased in patients with gastritis. The changes were more prominent at sites where gastritis was severe, but significant changes were also observed in neighboring areas where gastritis was less severe. Furthermore, the degree of changes was correlated with the pathological grade of the disease. The expression of CD10, the enzyme primarily involved in SP hydrolysis, was also decreased in patients with duodenitis. Based on these findings, we propose that decreased levels of VIP and CGRP and increased levels of SP contribute to pathological changes in gastric mucosa. Hence, new treatments targeting these molecules may have therapeutic and preventive effects.

Duodenal tuberculosis

Tuberculosis is a world wide communicable disease caused by tubercle bacilli discovered by Robert Kock in 1882. In 1993 WHO declared TB as a global emergency due to its world wide resurgence. It can involve any organ of the body. Abdomen is the fourth commonest site of involvement in the extra pulmonary tuberculosis after the lymph-nodes, skeletal and Genito urinary variants. In the gastro intestinal tract tuberculosis can affect any part from the mouth to the anus but ileocaecal area is a favourite location. Duodenal involvement is uncommon and accounts for only 2.5% of tuberculous enteritis. Major pathogens are Mycobacterium Tuberculosis and bovis and the usual route of entry is by direct penetration of the intestinal mucosa by swallowed organisms. (author)

The composition of T cell subtypes in duodenal biopsies are altered in coeliac disease patients.

Full Text Available One of the hallmarks of Celiac disease (CD is intraepithelial lymphocytosis in the small intestine. Until now, investigations to characterize the T cell subpopulations within the epithelial layer have not discriminated between the heterodimeric co-receptor molecule, CD8αβ, and the possibly immunoregulatory CD8αα homodimer molecule. Besides TCRαβ+ CD4+ cells, no other phenotypes have been shown to be gluten-reactive. Using flow cytometry on lymphocytes from duodenal biopsies, we determined that the number of B cells (CD3- CD19+ and the number of CD3+ CD4- CD8- double-negative (DN T cells were elevated 6-7 fold in children with CD. We next isolated and quantified intraepithelial lymphocytes (IELs from biopsies obtained from patients (both children and adults with CD, potential CD and non-CD controls. Flow cytometric analysis of the duodenal T cell subpopulations was performed including the markers TCRαβ, TCRγδ, CD4, CD8α and CD8β. Proportions of γδ T cells and CD8αβ+ cells among IELs were increased in CD patients, whereas proportions of CD4+ CD8αα+ and CD4+ single-positive T cells were decreased. Additionally, two gluten-reactive T cell lines (TCLs derived from CD biopsies were analyzed for changes in proportions of T cell subsets before and after gluten stimulation. In a proliferation assay, dividing cells were tracked with carboxyfluorescein succinimidyl ester (CFSE, and both αβ and γδ T cells proliferated in response to gluten. Changes in duodenal T cell subpopulations in potential CD patients followed the same pattern as for CD patients, but with less pronounced effect.

Selye's general adaptation syndrome: stress-induced gastro-duodenal ulceration and inflammatory bowel disease.

Fink, George

2017-03-01

Hans Selye in a note to Nature in 1936 initiated the field of stress research by showing that rats exposed to nocuous stimuli responded by way of a 'general adaptation syndrome' (GAS). One of the main features of the GAS was the 'formation of acute erosions in the digestive tract, particularly in the stomach, small intestine and appendix'. This provided experimental evidence for the view based on clinical data that gastro-duodenal (peptic) ulcers could be caused by stress. This hypothesis was challenged by Marshall and Warren's Nobel Prize (2005)-winning discovery of a causal association between Helicobacter pylori and peptic ulcers. However, clinical and experimental studies suggest that stress can cause peptic ulceration in the absence of H. pylori Predictably, the etiological pendulum of gastric and duodenal ulceration has swung from 'all stress' to 'all bacteria' followed by a sober realization that both factors play a role, separately as well as together. This raises the question as to whether stress and H. pylori interact, and if so, how? Stress has also been implicated in inflammatory bowel disease (IBD) and related disorders; however, there is no proof yet that stress is the primary etiological trigger for IBD. Central dopamine mechanisms seem to be involved in the stress induction of peptic ulceration, whereas activation of the sympathetic nervous system and central and peripheral corticotrophin-releasing factor appears to mediate stress-induced IBD. © 2017 Society for Endocrinology.

Acute mesenteric ischemia and duodenal ulcer perforation: a unique double pathology

2012-10-01

Full Text Available Abstract Background Acute mesenteric ischaemia and duodenal perforation are surgical emergencies with serious consequences. Patients presenting with acute mesenteric ischaemia alone face a high mortality rate as high as 60% whereas those presenting with peptic ulcer perforation the mortality rates range from 6-14%. There are very few reported cases of patients presenting with this dual pathology. Case presentation We report a unique case of a 53 year old Italian lady who presented with acute mesenteric ischaemia and duodenal perforation. This is the first report of massive bowel ischaemia and duodenal perforation with no apparent underlying common pathophysiology leading to this presentation. Conclusion Early management in the intensive care unit and appropriate surgical intervention maximised the patient’s chances of survival despite the poor prognosis associated with her dual pathology. The rare pathology of the patient described can be explained by two possible hypotheses: peptic ulcer disease causing duodenal ulceration, which precipitated ischaemic infarction of the small bowel. The second hypothesis is the patient developed a stress related ulcer following ischaemic bowel infarction secondary to arterial thrombosis.

Full Text Available Aims: Duodenal nodularity is an uncommon endoscopic appearance of numerous visible mucosal nodules in the proximal duodenum. In this retrospective study we aimed to determine the clinical significance and histopathologic features of duodenal nodularity in children. Materials and Methods: The medical records of the patients who were defined to have duodenal nodularity by endoscopy were reviewed. Statistical Analysis Used: The data were expressed as mean ± SD and percentages (%. Results: Seventeen patients with endoscopically defined duodenal nodularity were chosen. The mean age at diagnosis was 12.1 years (range: 6-17 years, 9 males. Abdominal pain (47% was the most common clinical symptom and antral nodularity (41% was the most common endoscopic finding in children with duodenal nodularity. Histopathologic evaluation of duodenal nodules revealed chronic inflammation in all patients, increased intercryptal and intraepithelial numbers of eosinophils in 70.5%, and villous atrophy in 47% of patients. Giardia infestation was demonstrated in 6 patients by histologic examination and/or Giardia lamblia-specific antigen positivity in stools. The clinical diagnoses of the patients have shown variations, such as celiac disease, giardiasis, secretory IgA deficiency, and Helicobacter pylori gastritis, and some of them were associated with the others. Conclusions: Although the endoscopic appearance is similar, clinical spectrum and pathologic features are not so similar and there are no specific histomorphologic findings for nodularity. The most demonstrative findings we observed in children were increased lymphocyte and/or eosinophil infiltration in the duodenal mucosa. We suggested that care should be taken in the evaluation of microbiological and immunologic etiologies causing this prominent inflammatory reaction.

Duodenal diverticulum is a pouch like protrusion of the mucous menibrane through a weak area or defect of the muscle layer of the duodenal wall. 206 cases of the duodenal diverticular out of the consecutive 4030 cases on upper G-I series during the period from Feb. 1977 to Aug. 1978 Department of Radiology, College of Medicine, Hanyang University were studied. The results were as follows; 1. Overall incidence of duodenal diverticular was 5.1 percent (5.0 percent in male, and 5.3 percent in female). 2. The incidence of duodenal diverticular were 1.4 percent in the age group below 19, 1.4 percent in the second decade, 0.8 percent in the third decade, 2.4 percent in the fourth decade, 5.3 percent in the fifth decade, 10.2 percent in the sixth decade, 9.2 percent in the seventh decade, and 17.0 percent in the age group over 70. Incidence of duodenal diverticular is higher in the older individuals. 3. Male was more frequently affected in the age group below 40, but more in females in the age group over 40. 4. 76.3 percent of duodenal diverticular were found in the concave side of the second portion of the duodenum. 5. Multiplicity of duodenal diverticular was 5.8 percent of cases. Triple duodenal diverticular were found in 1 case. 6. The size of duodenal diverticular was variable from 3 to 70 mm in diameter. More than half of duodenal diverticular were smaller than 9 mm in diameter. Large diverticular of more than 30 mm in diameter were 13.6 percent of cases. The size of the duodenal diverticular were relatively large in older age group.

Why is the coexistence of gastric cancer and duodenal ulcer rare? Examination of factors related to both gastric cancer and duodenal ulcer.

The coexistence of gastric cancer with duodenal ulcer has been found empirically to be rare, but why it is rare is difficult to explain satisfactorily. To elucidate this question, we carried out a literature review of the subject. The frequency with which the two diseases coexist is 0.1-1.7%, and the main factor associated with both gastric cancer and duodenal ulcer is Helicobacter pylori infection. However, there are marked differences between the disorders of hyperchlorhydria in duodenal ulcer, and hypochlorhydria in gastric cancer. The most acceptable view of the reason for the difference may be that the acquisition of H. pylori infection occurs mainly in childhood, so that the time of acquisition of atrophic gastritis may be the most important, and if atrophic gastritis is not acquired early, high levels of gastric acid may occur, and consequently acute antral gastritis and duodenal ulcer may occur in youth, whereas, in elderly individuals, persistent H. pylori infections and the early appearance of atrophic gastritis may be the causes of low gastric acid, and consequently gastric cancer may occur. In patients with duodenal ulcer, factors such as nonsteroidal anti-inflammatory drugs (NSAIDs) and dupA-H. pylori strains may contribute to preventing the early acquisition of atrophic gastritis, while acid-suppressive therapy and vascular endothelial growth factor and other entities may inhibit atrophic gastritis. In contrast, in gastric cancer, factors such as excessive salt intake, acid-suppressive therapy, polymorphisms of inflammatory cytokines, and the homB-H. pylori strain may contribute to the early acquisition of atrophic gastritis, while factors such as NSAIDs; fruits and vegetables; vitamins A, C, and E; and good nutrition may inhibit it.

2013-12-01

The presence of a periampullary duodenal diverticulum (PDD) is often observed during upper digestive tract barium meal studies and endoscopic retrograde cholangiopancreatography (ERCP). A few papers reported that the diverticulum had something to do with the incidence of pancreatitis. The aim of this study is to investigate if the presence of duodenal diverticula predisposes to the development of a pancreatic disease. A total 3966 patients who had undergone ERCP were studied retrospectively. They were divided into 2 groups-with and without PDD. Patients with a duodenal diverticula had a higher rate of acute pancreatitis. The duodenal diverticula is a risk factor for acute idiopathic pancreatitis. A multiple logistic regression to obtain adjusted estimate of odds and to identify if a PDD is a predictor of acute or chronic pancreatitis was performed. The software package STATISTICA 10.0 was used for analyzing the real data.

2006-12-01

Full Text Available Abstract Background Colo-duodenal fistula is a rare complication of malignant and inflammatory bowel disease. Cases with malignant colo-duodenal fistulae can present with symptoms from the primary, from the fistula or from metastatic disease. The fistula often results in diarrhoea and vomiting with dramatic weight loss. Upper abdominal pain is usually present as is general malaise both from the presence of the disease and from the metabolic sequelae it causes. The diarrhoea relates to colonic bacterial contamination of the upper intestines rather than to a pure mechanical effect. Vomiting may be faeculant or truly faecal and eructation foul smelling but in the case reports this 'classic' symptomatology was often absent despite a fistula being present and patent enough to allow barium through it. Occasionally patients will present with a gastro-intestinal bleed. Case presentation We present an unusual case of colorectal carcinoma, where a 65 year old male patient presented with diarrhoea and vomiting secondary to a malignant colo-duodenal fistula near the hepatic flexure. Adenocarcinoma was confirmed on histology from a biopsy obtained during the patient's oesophageogastroduodenoscopy, and the fistula was demonstrated in his barium enema. Staging computed tomography showed a locally advanced carcinoma of the proximal transverse colon, with a fistula to the duodenum and regional lymphadenopathy. The patient was also found to have subcutaneous metastasis. Following discussions at the multidisciplinary meeting, this patient was referred for palliation, and died within 4 months after discharge from hospital. Conclusion We present the case, discuss the management and review the literature. Colo-duodenal fistulae from colonic primaries are rare but early diagnosis may allow curative surgery. This case emphasises the importance of accurate staging and repeated clinical examination.

Acquired Duodenal Obstruction in Children

2008-10-01

Full Text Available Traumatic intramural hematoma of the duodenum is a rare cause of acquired duodenal obstruction in children, and a high degree of suspicion is therefore required to make an early and accurate diagnosis. We report a 6-year-old boy whose epigastrium was impacted by the handlebar of his bicycle during a traffic accident. The boy then experienced epigastralgia. Six days later, progressive bilious vomiting suggestive of gastrointestinal obstruction was noted. Imaging studies revealed a large hematoma extending from the fourth portion of the duodenum to the jejunum. Conservative methods of treatment failed to manage his condition. He underwent laparoscopic surgery to evacuate the hematoma. We also report a case of duodenal obstruction in a previously healthy 2-year-old girl who presented for the first time with acute symptoms of proximal intestinal obstruction. Contrast examinations showed apparent barium retention over the stomach and proximal duodenum. She underwent surgery due to persistent obstruction, and a mushroom-like foreign body was detected embedded in the orifice of the windsock duodenal web. After duodenoduodenostomy and removal of the bezoar, she had a smooth recovery and tolerated feeding well. We conclude that blunt abdominal trauma and incomplete duodenal obstruction, such as that caused by duodenal web, should be considered as possible causes of acquired proximal gastrointestinal obstruction in previously healthy children, despite their rarity.

Full Text Available Tissue transglutaminase (tTG is a ubiquitous multifunctional protein. It has roles in various cellular processes. tTG is a major target of autoantibodies in celiac disease, and its expression by immunohistochemistry in pediatric celiac disease has not been fully examined. We studied tTG expression in 78 pediatric duodenal biopsies by utilizing an antibody to transglutaminase 2. Serum tTG was positive in all celiac cases evaluated. Serum antiserum endomysial antibody (EMA and tTG were negative in all control subjects and in inflammatory bowel disease and eosinophilic gastroenteritis. There was a statistically significant difference between cases of celiac disease and normal controls in terms of tTG immunohistochemical staining in duodenal biopsies surface epithelium ( value = 0.0012. There was no significant statistical difference in terms of staining of the villous surface or crypt between the cases of celiac disease and cases with IBD ( value = 0.5970 and 0.5227, resp.. There was no detected correlation between serum tTG values and immunohistochemical positivity on duodenal biopsy in cases of celiac disease ( value = 1. There was no relationship between Marsh classification and positivity of villous surface for tTG ( value = 0.4955.

Full Text Available BACKGROUND The duodenal injury can pose a formidable challenge to the surgeon and failure to manage it properly may have devastating results. Over the centuries, there was little to offer the patient of acute abdomen beyond cupping, purgation and enemas, all of which did more harm than good. It was not until 1884 that Mikulicz made an attempt to repair a perforation. Recent statistics indicate roughly 10% of population develop gastric or duodenal ulcer in life time. Roughly 1-3% of population above the age of 20 years have some degree of peptic ulcer activity during any annual period. A detailed history with regards to the signs and symptoms of the patient, a meticulous examination, radiological and biochemical investigations help to arrive at a correct preoperative diagnosis. In this study, a sincere effort has been put to understand the demographic patterns, to understand the underlying aetiology and to understand the effectiveness of the standard methods of investigation and treatment in use today. METHODS This is a 24 months prospective study i.e., from September 2011 to September 2013 carried out at Dr. Pinnamaneni Siddhartha Institute of Medical Sciences & Research Foundation. The study included the patients presenting to Dr. Pinnamaneni Siddhartha Institute of Medical Sciences & Research Foundation to emergency ward with signs and symptoms of hollow viscus perforation. The sample size included 30 cases of duodenal perforation. RESULTS Duodenal ulcer perforation commonly occurs in the age group of 30-60 years, but it can occur in any age group. Majority of the patients were male. Smoking and alcohol consumption were risk factors in most cases (53.3% for the causation of duodenal ulcer perforation. Sudden onset of abdominal pain, situated at epigastrium and right hypochondrium was a constant symptom (100%. Vomiting, constipation and fever were not so common. CONCLUSION The emergency surgical management for perforated duodenal ulcer is by

Our understanding of the cause and treatment of peptic ulcer disease has changed dramatically over the last couple of decades. It was quite common some years ago to treat chronic ulcers surgically. These days, the operative treatment is restricted to the small proportion of ulcer patients who have complications such as perforation. The author reports seven cases of perforated duodenal ulcers seen in a surgical clinic between 1995 and 2001. Recommendations on the criteria for selecting the appropriate surgical intervention for patients with perforated duodenal ulcer are given. To decide on the appropriate surgical interventions for patients with perforated duodenal ulcer. These are case series of 7 patients who presented with perforated duodenal ulcers without a history of peptic ulcer disease. Seven patients presented with perforated duodenal ulcer 72 hours after perforation in a specialist surgical clinic in Kampala were analyzed. Appropriate management based on these patients is suggested. These patients were initially treated in upcountry clinics for acute gastritis from either alcohol consumption or suspected food poisoning. There was no duodenal ulcer history. As a result, they came to specialist surgical clinic more than 72 hours after perforation. Diagnosis of perforated duodenal ulcer was made and they were operated using the appropriate surgical intervention. Diagnosis of hangovers and acute gastritis from alcoholic consumption or suspected food poisoning should be treated with suspicion because the symptoms and signs may mimic perforated peptic ulcer in "silent" chronic ulcers. The final decision on the appropriate surgical intervention for patients with perforated duodenal ulcer stratifies them into two groups: The previously fit patients who have relatively mild physiological compromise imposed on previously healthy organ system by the perforation can withstand the operative stress of definitive procedure. The Second category includes patients who are

Purpose: To determine the incidence of duodenal toxicity in patients receiving intensity modulated radiation therapy (IMRT) for treatment of para-aortic nodes and to identify dosimetric parameters predictive of late duodenal toxicity. Methods and Materials: We identified 105 eligible patients with gynecologic malignancies who were treated with IMRT for gross metastatic disease in the para-aortic nodes from January 1, 2005, through December 31, 2009. Patients were treated to a nodal clinical target volume to 45 to 50.4 Gy with a boost to 60 to 66 Gy. The duodenum was contoured, and dosimetric data were exported for analysis. Duodenal toxicity was scored according to Radiation Therapy Oncology Group criteria. Univariate Cox proportional hazards analysis and recursive partitioning analysis were used to determine associations between dosimetric variables and time to toxicity and to identify the optimal threshold that separated patients according to risk of toxicity. Results: Nine of the 105 patients experienced grade 2 to grade 5 duodenal toxicity, confirmed by endoscopy in all cases. The 3-year actuarial rate of any duodenal toxicity was 11.7%. A larger volume of the duodenum receiving 55 Gy (V55) was associated with higher rates of duodenal toxicity. The 3-year actuarial rates of duodenal toxicity with V55 above and below 15 cm{sup 3} were 48.6% and 7.4%, respectively (P<.01). In Cox univariate analysis of dosimetric variables, V55 was associated with duodenal toxicity (P=.029). In recursive partitioning analysis, V55 less than 13.94% segregated all patients with duodenal toxicity. Conclusions: Dose-escalated IMRT can safely and effectively treat para-aortic nodal disease in gynecologic malignancies, provided that care is taken to limit the dose to the duodenum to reduce the risk of late duodenal toxicity. Limiting V55 to below 15 cm{sup 3} may reduce the risk of duodenal complications. In cases where the treatment cannot be delivered within these constraints

Gastro-duodenal perforations are common and may complicate peptic ulcer disease. Management is often by surgical closure. To determine the patterns of presentation and mode of management of duodenal ulcer perforations. Retrospective review of patients with duodenal ulcer perforations seen at the Obafemi Awolowo University Teaching Hospital between June 2001 and July 2011. Patients' records were reviewed for demography, duration of disease, probable risk factors, type of surgery and complications. Data obtained was analyzed using SPSS 15.0. Forty- five patients were reviewed. There were 37 males (82.2%). Mean age was 39.7years (range 15-78years). There were 10 (22.6%) students and 8(17.8%) farmers. NSAIDs abuse (11), previous peptic ulcer disease (2), and no prior dyspeptic symptoms (20) constituted 24.4%, 4.4% and 44.4% respectively of cases. Seven (16%) patients presented less than 24 hours of onset of illness. Forty one perforations (91.1%) involved the first part of duodenum. Twenty two (49%) patients had Graham's omental patch. We had one (2.2%) failed repair and six (13.3%) mortalities. Late presentation of duodenal ulcer perforation is common with high mortality. Pragmatic surgical intervention with Graham's omentopexy with broad spectrum antibiotics is still commonly practiced.

Refractory celiac disease is characterized by mucosal damage in patients with celiac disease despite a gluten-free diet. Little is known about the mechanisms that cause persistent intestinal inflammation in these patients. We performed a case-control study of 17 consecutive patients diagnosed with refractory celiac disease from 2001 through 2014 (median age, 51 y; 10 women) and 24 patients with uncomplicated celiac disease (controls) to determine whether refractory disease is associated with infection by lymphotropic oncogenic viruses. We performed real-time PCR analyses of duodenal biopsy samples from all patients to detect Epstein-Barr virus (EBV), human herpesvirus-8, and human T-cell lymphotropic virus-I, -II, or -III. We used in situ hybridization and immunohistochemical analyses to identify infected cells and viral proteins. We did not detect human herpesvirus-8 or human T-cell lymphotropic viruses in any of the biopsy specimens. However, 12 of 17 (70.5%) biopsy specimens from patients with refractory celiac disease were positive for EBV, compared with 4 of 24 (16.6%) biopsy specimens from controls (P disease and enteropathy-associated T-cell lymphoma.

Full Text Available INTRODUCTION Perforated duodenal ulcer, the most catastrophic complication was Associated with high mortality in the past due to late presentation of the patients, delay in surgery and lack of antibiotics. Various authors state that the incidence of peptic ulcer disease and perforation has been declining for the past 3 decades. Because of advances in the medical therapy of peptic ulcer with a wide range of drugs the management of peptic ulcer disease has been changing and the role of surgery has been declining. Perforation is usually seen in 3rd and 4th decades with a male preponderance and the epidemiological trend is not the same worldwide. Incidence is slightly declining in western countries. The present study has been done during the period between 2013 and 2014 in S. V. R. R. Government general hospital Tirupati. AIMS AND OBJECTIVES The aim of the present study is to analyze the probable factors for increase in incidence of duodenal ulcer perforation, with particular emphasis on assessment of impact of H2 receptor antagonists and Proton Pump inhibitors on the incidence of perforation. STUDY SETTING S. V. Medical College, Department of General Surgery, Tirupati. STUDY PERIOD Patients attending S. V. Medical College, Department of General Surgery with perforation during the period from November 2013 to October 2014. INCLUSION CRITERIA Patients between age group of more than 14 years presenting with pain abdomen and who are diagnosed to have peritonitis due to duodenal ulcer perforation. EXCLUSION CRITERIA Patients with peritonitis due causes other than duodenal ulcer. STUDY METHOD Prospective Observational study among the selected patients. Total numbers of peptic ulcer cases that were admitted in this hospital and treated either medically or surgically were noted. The details of their clinical history and findings, investigation reports, operative findings, post-operative complications were recorded. Simple closure was performed for all the

Mycophenolate mofetil (MMF) is an immunosupressor agent frequently used in patients after bone marrow or solid organ transplants. The most common adverse reactions of the drug are gastrointestinal, specially diarrhea and vomiting. We report a 53-year-old male, that received a heart transplant receiving immunosuppression with cyclosporine, mycophenolate mofetil and prednisone. Six months after the transplant, the patient started with diarrhea, anorexia and weight loss. A duodenal biopsy showed villous atrophy. Celiac disease and the presence of parasites were discarded. Mycophenolate mofetil was discontinued and one week later, diarrhea subsided. Two months later the patient was asymptomatic and recovered weight. A new duodenal biopsy showed absence of villous atrophy.

Changes in gastroduodenal blood flow have been implicated in the pathogenesis of duodenal ulcer. The authors have studied duodenal blood flow during the development of an acute to chronic duodenal ulcer by using the abscopal model, in which ulcers are generated as an indirect effect of lower mediastinal irradiation. Female CFLP mice were randomly allocated to one of three groups. Irradiated ``controls`` received 18 Gy 250 kV X-rays to the upper mediastinum. The lower mediastinum group received the same dose of irradiation, which has been shown to induce typical chronic duodenal ulcers in 45% of animals so treated. Animals were studied by means of radiolabelled microspheres 3 or 7 days later. Proximal duodenal blood flow specifically was reduced by 32% in the lower mediastinum group compared with irradiated controls at 7 days. There was no significant difference in blood flow to the stomach and to the distal duodenum. The decrease in proximal duodenal blood flow in the lower mediastinum group did not differ in the five animals that developed ulcer compared with the seven that did not. Although, there is an overall decrease in duodenal blood flow associated with chronic duodenal ulcer, reduced blood flow may not explain individual susceptibility to ulceration. 21 refs., 1 fig., 2 tabs.

The advent of proton pump inhibitors and helicobacter pylori eradication in the management of chronic peptic ulcer disease has reduced the operative treatment of this condition to its complications. Perforated duodenal ulcer remains a major life threatening complication of chronic peptic ulcer disease. This retrospective study reviews our experience at the Royal Victoria Teaching Hospital. All patients with clinical diagnosis of perforated duodenal ulcer seen in this hospital between June 2003 and October 2005 were included in this study. Data extracted from their hospital records were analyzed for age, sex, duration of symptoms, previous history of peptic ulcer disease, use of NSAIDS, main presenting features, investigations, resuscitative measures, time of surgery, operative findings, and type of surgery offered, complications and mortality. After resuscitation, laparotomy followed by simple closure or definitive ulcer surgery and helicobacter pylori eradication therapy was given to all the patients. Duration of follow up ranged 8 to 12 months with endoscopy in some patients. There were 41 patients with intraoperative diagnosis of acute perforated duodenal ulcer seen over the study period, comprising 34 males (82.9%) and 7 females (17.1%), a male female ratio of 4.8:1, age range of 18-77 years and a mean age of 45.49 +/- 14.46 years. Previous history of peptic ulcer disease was found in 32 (78.6%) of the patient and the main presenting features were sudden onset of severe abdominal pain in 95.1% of cases and fever in 65.8%. Features of frank peritonitis were demonstrable in all the patients and 11 (26.8%) presented in shock. Plain chest x-rays demonstrated gas under the diaphragm in 21(65.6%) of the patients. After adequate resuscitation, all the patients underwent laparotomy where the abdomen was explored, the diagnosis of perforated duodenal ulcer was confirmed and 29 (70.7%) had simple closure of the perforation with omentum (after Graham).

Raghunath Rajat

2015-01-01

Full Text Available Scrub typhus is an acute febrile illness usually presenting with fever, myalgia, headache, and a pathognomonic eschar. Severe infection may lead to multiple organ failure and death. Gastrointestinal tract involvement in the form of gastric mucosal erosions and ulcerations owing to vasculitis resulting in gastrointestinal bleeding is common. This process may worsen a pre-existent asymptomatic peptic ulcer, causing duodenal perforation, and present as an acute abdomen requiring surgical exploration. We report the case of a patient with no previous symptoms or risk factors for a duodenal ulcer, who presented with an acute duodenal perforation, probably precipitated by scrub typhus infection.

Full Text Available Metastatic malignant mesothelioma of the pleura is uncommon at the time of initial diagnosis. The gastrointestinal lumen is rarely found at autopsy in patients with widespread disease. Here, we describe an extremely rare case of isolated duodenal metastasis of sarcomatoid mesothelioma of the pleura in a 73-year-old man, without memory of any direct exposure to asbestos. The possibility of gastrointestinal tract metastasis should be considered in the presence of anemia or positive occult blood test in patients with malignant pleural mesothelioma.

Diagnosis of celiac disease is difficult when the combined results of serology and histology are inconclusive. Studies using flow cytometry of intraepithelial lymphocytes (IELs) have found that celiac patients have increased numbers of γδ IELs, along with a decrease in CD3-CD103 + IELs. The objective of this article is to assess the role of flow cytometric analysis of IELs in the diagnosis of celiac disease in difficult cases. A total of 312 patients with suspicion of celiac disease were included in the study. Duodenal biopsy samples were used for histological assessment and for flow cytometric analysis of IELs. In 46 out of 312 cases (14.7%) the combination of serology and histology did not allow the confirmation or exclusion of celiac disease. HLA typing had been performed in 42 of these difficult cases. Taking into account HLA typing and the response to a gluten-free diet, celiac disease was excluded in 30 of these cases and confirmed in the remaining 12. Flow cytometric analysis of IELs allowed a correct diagnosis in 39 out of 42 difficult cases (92.8%) and had a sensitivity of 91.7% (95% CI: 61.5% to 99.8%) and a specificity of 93.3% (95% CI: 77.9% to 99.2%) for the diagnosis of celiac disease in this setting. Flow cytometric analysis of IELs is useful for the diagnosis of celiac disease in difficult cases.

To observe the relatively specific effect of electroacupuncture (EA) of "Xiajuxu" (ST 39, the lower hesea paint of the small intestine), etc. on the level of serum TNF-alpha, lnterleukin-1 P (IL-1 P) and high mobility group protein B 1 (HMGB 1) contents, and duodenum a7 nicotinic acetyicholine receptor (nAchR) expression in duodenal ulcer rats, so as to explore its mechanisms underlying improving duodenal ulcer. Sixty SD rats were randomly divided into 6 groups: normal control, model, Xiajuxu (ST 39), Zusanli (ST 36), Shangjuxu (ST 37) and Yanglingquan (GB 34). The duodenal ulcer model was established by subcutaneous injection of 10% Cysteamine Hydrochloride (300 mg/kg), following by giving the rats with access to water containing Cysteamine. EA (10 Hz/50 Hz, 1- 3 mA) was applied to bilateral ST 39, ST 36, ST 37 and GB 34 for 30 min, once daily for 10 days. The ulcer scores (0-5 points) of the duodenal mucosa were assessed according to modified Moraes' methods. Serum TNF-alpha, IL-1 beta and HMGB 1 levels were assayed by ELISA and the expression of neuronal a7 nAchR in the duodenal tissue was detected by Western blot. After modeling, the ulcer score, serum TNF-alpha, IL-i p and HMGB 1 contents were significantly increased (P0.05). EA stimulation of ST 36, ST 37 and ST 39 can reduce ulcer injury in duodenal ulcer model rats, which may be associated with their effects in down-regulating serum TNF-alpha, IL-1 beta and HMGB 1 contents and up-regulating alpha7 nAchR expression of the duodenal tissue, possibly by suppressing immune and inflammatory reactions and regulating nicotinic activity.

Shin, Tae Beom; Kim, Young Hwan; Seong, Chang Kyu

2004-01-01

To assess the efficacy and safety of arterial embolotherapy in patients with massive duodenal hemorrhage. Between January 1999 and June 2002, 25 patients (age: 34-81, mean 58, male: 19, female: 6) underwent arterial embolization for duodenal hemorrhage after failed endoscopic therapy. The hemorrhage originated from duodenal ulcer in sixteen patients, from cancer with duodenal invasion in five patients, from endoscopic sphincterectomy in two patients, and from pseudoaneurysm complicating acute pancreatitis in two patients. Hemorrhage was detected at endoscopy and an attempt was made to treat it endoscopically in all patients, but failed in each case. At angiography, direct bleeding signs such as contrast extravasation or pseudoaneurysm were demonstrated in nineteen patients. In the six patients without angiographic evidence of bleeding, blind embolization of the gastroduodenal artery was performed based on the endoscopic examination. Microcoil and gelfoam particles were used as embolic agents. Hemostasis was achieved immediately after embolotherapy in 21 patients (84%). Bleeding recurred in 4 patients (16%), and of these cases, one was successfully treated purely by endoscopic means, a second was reembolized three times due to bleeding from the collateral vessels of the tumor and the two others were treated by surgery. After the procedure, six patients died (24%). The causes of death were disseminated intravascular coagulopathy, multiorgan failure, sepsis and acute renal failure. The underlying diseases of the deceased patients were cancers with duodenal invasion (n=4) and abdominal aortic aneurysm with ischemic colitis (n=1). Transarterial embolotherapy in the case of massive duodenal hemorrhage is a safe and effective procedure. Even in the absence of angiographic evidence of bleeding, blind embolization of the gastroduodenal artery is effective for patients in the surgically high risk group

Low-velocity gunshot wounds cause most civilian duodenal injuries. The objective of this study was to describe a simplified surgical algorithm currently in use in a South African civilian trauma center and to verify its validity by measuring morbidity and mortality. A retrospective chart review of patients with duodenal gunshot injuries during the study period January 1999 to December 2003 was performed. Data points accrued included patient demographics, admission hemodynamic status and resuscitative measures, laparotomy damage control procedures, methods of surgical repair of the duodenal injury, associated injuries, length of intensive care and hospital stays, complications, and mortality. A total of 75 consecutive patients with gunshot injuries to the duodenum were reviewed. Primary repair was performed in 54 patients (87%), resection and reanastomosis in 7 (11%), and pancreatoduodenectomy in 1 (2%) during the initial phases. The overall morbidity and mortality were 58% and 28%, respectively. Duodenum-related complications were recorded in nine (15%) patients: two duodenal fistulas, one duodenal obstruction, and six cases of suture-line dehiscence. Overall and duodenum-related morbidity rates in patients with combined pancreatoduodenal injuries were 83% and 17%, respectively. Duodenum-related mortality occurred in three (4.8%) patients. Most civilian low-velocity duodenal gunshot injuries treated with simple primary repair result in overall morbidity, mortality, and duodenum-related complication rates comparable to those in reports where more complex surgical procedures were employed. Primary repair is also applicable for most combined pancreatic and duodenal gunshot injuries.

Full Text Available Objective: Several studies have been performed concerning pathologies of the stomach and esophagus in the pediatric age group. However, there have been very few studies of duodenal pathologies in children. The authors aimed to examine the clinical, endoscopic, and histopathological characteristics, as well as the etiology of duodenal pathologies in children. Method: Patients aged between 1 and 17 years undergoing esophagogastroduodenoscopy during two years at this unit, were investigated retrospectively. Demographic, clinical, endoscopic data, and the presence of duodenal pathologies, gastritis, and esophagitis were recorded in all of the children. Results: Out of 747 children who underwent endoscopy, duodenal pathology was observed in 226 (30.3% patients. Pathology was also present in the esophagus in 31.6% of patients and in the stomach in 58.4%. The level of chronic diarrhea was higher in patients with duodenal pathology when compared with those without duodenal pathology (p = 0.002, OR: 3.91, 95% CI: 1.59–9.57. Helicobacter pylori infection was more common in patients with pathology in the duodenum (59.3%. Conclusion: Duodenal pathology was detected in 30.3% of the present patients. A significantly higher level of chronic diarrhea was observed in subjects with duodenal pathologies compared to those with no such pathology. The rate of Helicobacter pylori infection was considerably higher than that in previous studies. In addition, there is a weak correlation between endoscopic appearance and histology of duodenitis.

Parenteral nutrition (PN) has been found to influence duodenal motility in animals. Choline is an essential nutrient, and its deficiency is related to PN-associated organ diseases. Therefore, this study was aimed to investigate the role of choline supplementation in an infant rat model of PN-associated duodenal motility disorder. Three-week-old Sprague-Dawley male rats were fed chow and water (controls), PN solution (PN), or PN plus intravenous choline (600 mg/kg) (PN + choline). Rats underwent jugular vein cannulation for infusion of PN solution or 0.9% saline (controls) for 7 days. Duodenal oxidative stress status, concentrations of plasma choline, phosphocholine, and betaine and serum tumor necrosis factor (TNF)-α were assayed. The messenger RNA (mRNA) and protein expression of c-Kit proto-oncogene protein (c-Kit) and membrane-bound stem cell factor (mSCF) together with the electrophysiological features of slow waves in the duodenum were also evaluated. Rats on PN showed increased reactive oxygen species; decreased total antioxidant capacity in the duodenum; reduced plasma choline, phosphocholine, and betaine; and enhanced serum TNF-α concentrations, which were reversed by choline intervention. In addition, PN reduced mRNA and protein expression of mSCF and c-Kit, which were inversed under choline administration. Moreover, choline attenuated depolarized resting membrane potential and declined the frequency and amplitude of slow waves in duodenal smooth muscles of infant rats induced by PN, respectively. The addition of choline to PN may alleviate the progression of duodenal motor disorder through protecting smooth muscle cells from injury, promoting mSCF/c-Kit signaling, and attenuating impairment of interstitial cells of Cajal in the duodenum during PN feeding. © 2015 American Society for Parenteral and Enteral Nutrition.

Early Rupture of an Ultralow Duodenal Stump after Extended Surgery for Gastric Cancer with Duodenal Invasion Managed by Tube Duodenostomy and Cholangiostomy

Full Text Available When dealing with gastric cancer with duodenal invasion, gastrectomy with distal resection of the duodenum is necessary to achieve negative distal margin. However, rupture of an ultralow duodenal stump necessitates advanced surgical skills and close postoperative observation. The present study reports a case of an early duodenal stump rupture after subtotal gastrectomy with resection of the whole first part of the duodenum, complete omentectomy, bursectomy, and D2+ lymphadenectomy performed for a pT3pN2pM1 (+ number 13 lymph nodes adenocarcinoma of the antrum. Duodenal stump rupture was managed successfully by end tube duodenostomy, without omental patching, and tube cholangiostomy. Close assessment of clinical, physical, and radiological signs, output volume, and enzyme concentration of the tube duodenostomy, T-tube, and closed suction drain, which was placed near the tube duodenostomy site to drain the leak around the catheter, dictated postoperative management of the external duodenal fistula.

2000-01-01

Diagnosis of duodenal and pancreatic injuries is frequently delayed, and optimal treatment is often controversial. Fourteen children with duodenal and/or pancreatic injuries secondary to blunt trauma were treated between 1980 and 1997. The pancreas was injured in all but 1 child. An associated duodenal injury was present in 4. The preoperative diagnosis was suspected in only 6 patients based on clinical signs and ultrasonography. One patient was treated successfully conservatively; all the others required surgical management. At operation, three procedures were used: peripancreatic drainage, suture of the gland or duodenum with drainage, and primary distal pancreatic resection without splenectomy. A duodenal resection with reconstruction by duodeno-duodenostomy was performed in 1 case. The overall complication rate was 14%: 1 fistula and 1 pseudocyst. Pancreatic ductal transection was recognized 3 days after the initial laparotomy by endoscopic retrograde cholangiopancreatography (ERCP). The mortality was 7%; 1 patient died from septic and neurologic complications. When the diagnosis of pancreatic ductal injuries is a major problem, ERCP may be a useful diagnostic procedure. Pancreatic injuries without a transected duct may often be treated conservatively. The surgical or conservative management of duodenal hematomas is still controversial; other duodenal injuries often need surgical treatment.

Presentation and Surgical Management of Duodenal Duplication in Adults

2015-01-01

Full Text Available Duodenal duplications in adults are exceedingly rare and their diagnosis remains difficult as symptoms are largely nonspecific. Clinical presentations include pancreatitis, biliary obstruction, gastrointestinal bleeding from ectopic gastric mucosa, and malignancy. A case of duodenal duplication in a 59-year-old female is presented, and her treatment course is reviewed with description of combined surgical and endoscopic approach to repair, along with a review of historic and current recommendations for management. Traditionally, gastrointestinal duplications have been treated with surgical resection; however, for duodenal duplications, the anatomic proximity to the biliopancreatic ampulla makes surgical management challenging. Recently, advances in endoscopy have improved the clinical success of cystic intraluminal duodenal duplications. Despite these advances, surgical resection is still recommended for extraluminal tubular duplications although combined techniques may be necessary for long tubular duplications. For duodenal duplications, a combined approach of partial excision combined with mucosal stripping may offer advantage.

Our presentation comprises results of two studies: The first was an experimental investigation of 60 Wistar-strain rats used in a toxicological study. The other part analysed stress changes in the duodenal mucosa in the human autopsy material. Both humans and rats had been exposed to stress and showed similar histological changes. In the rats the same duodenal lesions were present both in the test group and the control animals in the toxicological study. Lesions consisted of oedema of the duodenal villi and erosions in the tips of the villi. We believe that in the experimental group the stress was caused by restraining the animals by daily introduction of the gastric metallic tube, by taking blood from the retrobulbar plexus, and by anaesthesia. The autopsy study comprised 35 cases displaying congestion and macroscopically recognizable multifocal bleeding into the duodenal mucosal folds. The microscopic investigation revealed bleeding into the mucosal villi and small erosions. In some cases there were cuneiform mucosal infarcts extending into the submucosa. In the humans, severe cardiovascular diseases and circulatory disturbances represented the main causes of the stress. Local hypoxia and gastric juice acidity were involved in the pathogenesis of the duodenal mucosal changes.

Purpose. The purpose of this study is to evaluate the efficacy of palliation of malignant biliary and duodenal obstruction with combined metallic stenting under fluoroscopy guidance. Materials and Methods. A retrospective analysis of 9 patients (6 men and 3 women) who underwent biliary and duodenal stenting was performed. The mean age of patients was 61 years (range: 42-80 years). The causes of obstruction were pancreatic carcinoma in 7 patients, cholangiocellular carcinoma in one, and duodenal carcinoma in the other. Biliary and duodenal stents were placed simultaneously in 4 patients. In other 5 patients dudodenal stents were placed after biliary stenting when the duodenal obstruction symptoms have developed. In two patients duodenal stents were advanced via transgastric approach. Results. Technical success rate was 100 %. After percutaneous biliary drainage and stenting bilirubin levels decreased to normal levels in 6 patients and in remaining 3 patients mean reduction of 71% in bilirubin levels was achieved. Tumoral ingrowth occurred in one patient and percutaneous biliary restenting was performed 90 days after the initial procedure. Of the 9 patients, 6 patients were able to tolerate solid diet, whereas 2 patients could tolerate liquid diet and one patient did not show any improvement. Mean survival periods were 111 and 73 days after biliary and duodenal stenting, respectively. Conclusion. Combined biliary and duodenal stent placement which can be performed under fluoroscopic guidance without assistance of endoscopy is feasible and an effective method of palliation of malignant biliary and duodenal obstructions. If transoral and endoscopic approaches fail, percutaneous gastrostomy route allows duodenal stenting

Pancreatic injuries are rare complications after blunt abdominal trauma and usually the result of a direct force separating the pancreatic body in front of the vertebral column. This case report describes the uncommon event of a severe pancreatic and duodenal injury (stage IV b of Lukas) in which the combination of a direct force and the setting of a preexisting penetrating ulcer of the duodenum caused the extent of the pancreatic and duodenal injury [9]. Because of the preexisting lesion a Whipple procedure had to be performed. This case report demonstrates the influence of chronic abdominal diseases on the outcome of blunt abdominal trauma.

Acute Necrotizing Esophagitis is an uncommon pathology, characterized by endoscopic finding of diffuse black coloration in esophageal mucosa and histological presence of necrosis in patients with upper gastrointestinal bleeding. The first case of acute necrotizing esophagitis followed by duodenal necrosis, in 81 years old woman with a positive history of Type 2 Diabetes Mellitus, Hypertension, and usual intake of Nonsteroidal Anti-inflammatory drugs, is reported. Although its etiology remains unknown, the duodenal necrosis suggests that ischemia could be the main cause given that the branches off the celiac axis provide common blood supply to the distal esophageal and duodenal tissue. The massive gastroesophagic reflux and NSAID intake could be involved. PMID:27957030

Duodenal diverticulum is common, but its perforation is a rare complication. Duodenal diverticulum perforation requires prompt treatments because of its high mortality rate. However, an accurate diagnosis is difficult to make due to nonspecific symptoms and signs. It can be misdiagnosed as pancreatitis, cholecystitis, or peptic ulcer. Herein, we report a case of perforated duodenal diverticulum caused by bezoar in a 33-year-old woman whom was diagnosed by abdomen computed tomography and ultrasonography.

One of the perceived disadvantages of the biliopancreatic diversion with duodenal switch operation is diarrhea. The aim of this study was to compare the bowel habits of patients after duodenal switch operation or Roux-en-Y gastric bypass. A prospective comparative case series design was used. Forty-six patients who underwent duodenal switch (n=28) or gastric bypass (n=18) were asked to complete a daily diary for 14 days after losing least 50% of their excess body weight. Data were collected on number of bowel episodes, incontinence, urgency, stool consistency, and awakening from sleep to defecate. Background variables were recorded from the medical files. The duodenal switch group was heavier (body mass index 53.5 vs 47.0 kg/m(2), p=0.03) and older (47.5 vs 41.0 years, p=NS) than the gastric bypass group. Median time to 50% excess body weight loss was 22 months in the duodenal switch group compared to 10.0 months in the gastric bypass group (p=0.001). Patients after duodenal switch surgery reported a median of 23.5 bowel episodes over the 14-day study period compared to 16.5 in the gastric bypass group (p=NS). There was no between-group differences in any of the other bowel parameters studied. Although duodenal switch is associated with more bowel episodes than gastric bypass, the difference is not statistically significant. Bowel habits are similar in patients who achieve 50% estimated body weight loss with duodenal switch surgery or gastric bypass.

Full Text Available Abstract Background Duodenal ulcer perforations are a common surgical emergency, but literature is silent on the exact definition, incidence, management and complications of large perforations of duodenal ulcers. Methods The case files of 162 patients who underwent emergency laparotomy for duodenal ulcer perforations over a period of three years (2001 – 2003 were retrospectively reviewed and sorted into groups based on the size of the perforations – one group was defined as 'small 'perforations (less than 1 cm in diameter, another 'large' (when the perforation was more than 1 cm but less than 3 cms, and the third, 'giant'(when the perforation exceeded 3 cm. These groups of patients were then compared with each other in regard to the patient particulars, duration of symptoms, surgery performed and the outcome. Results A total of 40 patients were identified to have duodenal ulcer perforations more than 1 cm in size, thus accounting for nearly 25 % of all duodenal ulcer perforations operated during this period. These patients had a significantly higher incidence of leak, morbidity and mortality when compared to those with smaller perforations. Conclusion There are three distinct types of perforations of duodenal ulcers that are encountered in clinical practice. The first, are the 'small' perforations that are easy to manage and have low morbidity and mortality. The second are the 'large' perforations, that are also not uncommon, and omental patch closure gives the best results even in this subset of patients. The word 'giant' should be reserved for perforations that exceed 3 cms in diameter, and these are extremely uncommon.

Coeliac disease (CD) is a chronic immune-mediated small intestine enteropathy precipitated by gluten in genetically predisposed individuals. Adult presentation is often atypical and malabsorption of vitamins and minerals is common, with a consequent disturbance of bone metabolism. We aim to evaluate laboratory deficiencies related to bone metabolism and the relationship between severity of histological damage and degree of bone mass loss at diagnosis of CD. A retrospective cross-sectional study of 176 adult coeliac patients was carried out. All patients fulfilled the histopathological criteria for CD. Biochemical data were analysed (calcium/phosphate/alkaline-phosphatase/vitamin D/parathormone). Duodenal histology was classified according to the Marsh classification. Bone mass density (BMD) at the lumbar and femoral regions measured by dual X-ray absorptiometry. A P-value of less than 0.05 was considered significant. No correlation was found between the presence of gastrointestinal symptoms and the Marsh histopathological stage (P>0.05). Vitamin D deficiency was most common (44.5%), whereas only 5.7% had hypocalcaemia. Calcium was lower (Pcoeliac patients older than 30 years, evaluation of bone biomarkers and dual X-ray absorptiometry examination should be considered.

Activation of protein kinase C (PKC) enzymes in liver and brain alters hepatic glucose metabolism, but little is known about their role in glucose regulation in the gastrointestinal tract. We investigated whether activation of PKC-δ in the duodenum is sufficient and necessary for duodenal nutrient sensing and regulates hepatic glucose production through a neuronal network in rats. In rats, we inhibited duodenal PKC and evaluated whether nutrient-sensing mechanisms, activated by refeeding, have disruptions in glucose regulation. We then performed gain- and loss-of-function pharmacologic and molecular experiments to target duodenal PKC-δ; we evaluated the impact on glucose production regulation during the pancreatic clamping, while basal levels of insulin were maintained. PKC-δ was detected in the mucosal layer of the duodenum; intraduodenal infusion of PKC inhibitors disrupted glucose homeostasis during refeeding, indicating that duodenal activation of PKC-δ is necessary and sufficient to regulate glucose homeostasis. Intraduodenal infusion of the PKC activator 1-oleoyl-2-acetyl-sn-glycerol (OAG) specifically activated duodenal mucosal PKC-δ and a gut-brain-liver neuronal pathway to reduce glucose production. Molecular and pharmacologic inhibition of duodenal mucosal PKC-δ negated the ability of duodenal OAG and lipids to reduce glucose production. In the duodenal mucosa, PKC-δ regulates glucose homeostasis. Copyright © 2011 AGA Institute. Published by Elsevier Inc. All rights reserved.

Full Text Available Peptic ulcers are a serious problem worldwide, and affect about 4 million people each year. Their etiology is connected with the presence of Helicobacter pylori, the act of smoking, drinking alcohol, being stress, and taking excessively nonsteroidal anti-inflammatory drugs, as well as steroids. The most common symptoms are abdominal pain, nausea, chest pain and fatigue, while less frequent symptoms include vomiting and weight loss. Helicobacter pylori is responsible for about 80% of gastric and 90% of duodenal ulcer cases. In this work, an analysis is made of a correlation between stomach or duodenal ulcer and gender, residence and number of patients hospitalized in the Almaty hospital №1, from 2009-2012, in order to learn about trends in the incidence of these diseases in Kazakhstan. A total number of 950 patients with stomach and duodenal ulcers, in 2009-2012, were questioned. The patient’s residence, gender and stomach or duodenal ulcer problem were taken into account in the study. The result of this work reveals that the largest amount of hospitalized patients suffering from stomach or duodenal ulcers came from urban areas. Moreover, more women than men suffered from peptic ulcers. Furthermore, the number of patients admitted to the hospital due to duodenal ulcers did not show any variation throughout the study. However, the least number of patients suffering from gastric ulcers was noticed in December 2009, and the greatest was in October and November 2011. The obtained data show that ulcers are a serious problem in Kazakhstan.

Duodenal diverticula demonstrated by barium examination

Energy Technology Data Exchange (ETDEWEB)

Christiansen, T.; Thommesen, P.

An investigation for biliary tract calculi and food-stimulated gastro-oesophageal reflux was carried out in 37 patients with duodenal diverticula demonstrated by barium examination. Sixty per cent of the diverticula were located in the descending part of the duodenum. Biliary tract calculi were demonstrated in 38 per cent and food-stimulated gastro-oesophageal reflux in 81 per cent of the patients. The detection of a duodenal diverticulum should result in a supplementary investigation for gallstones and gastrooesophageal reflux and its sequelae.

A case of duodenal obstruction by a congenital duodenal web in a 34-year-old woman is presented. A mucosal diaphragm obstructed the duodenum. It showed an excentric opening of 0.8 cm diameter, but the dilated diaphragm caused a total stop during the last months. Despite a typical history, exact X-ray, and endoscopic examination, the correct preoperative diagnosis was not found, because nobody thought it possible, that a mucosal diapharm of the duodenum could persist for 34 years.

The new ESPGHAN guidelines for diagnosis of paediatric coeliac disease suggest to avoid biopsy in genetically pre-disposed and symptomatic individuals with positive anti-endomysial antibodies (EMA) and anti-tissue transglutaminases (a-tTG). However, duodenal biopsy remains the gold standard in adult coeliac disease. To establish the cut-off values of a-tTG, which would: predict the presence of duodenal histology (Marsh ≥2) diagnostic for coeliac disease; and predict the presence of villous atrophy (Marsh 3) in adults. We performed an observational prospective study including all consecutive adult patients with suspected coeliac disease. All subjects were tested for EMA and a-tTG. Coeliac disease diagnosis was made in presence of Marsh ≥2, a-tTG >7 U/mL and positive EMA. A ROC curve was constructed to establish the best specificity cut-off of a-tTG levels, which would predict the presence of Marsh ≥2 and Marsh 3 at histology. The study included 310 patients with positive antibodies. Histology showed Marsh 1 in 8.7%, Marsh 2 in 3.5%, Marsh 3 in 87.7%. The best cut-off value of a-tTG for predicting Marsh ≥2 was 45 U/mL (sensitivity 70%; specificity 100%; PPV 100%; NPV 24.1%); the best cut-off for predicting villous atrophy was 62.4 U/mL (sensitivity 69%, specificity 100%; PPV 100%; NPV 31%). The diagnosis of coeliac disease can be reached without histology in adult patients with positive EMA and a-tTG levels >45 U/mL. An a-tTG level >62.4 was diagnostic for villous atrophy. These results could contribute to improving the diagnosis of coeliac disease by allowing for a significant reduction in diagnosis-related costs. © 2014 John Wiley & Sons Ltd.

Full Text Available Allthough infrequent, digestive fistulae in HIV/AIDS patients have been reported throughout the digestive tract from the esophagus to the anus, with predominance of esophageal fistulae. AIDS/HIV-associated opportunistic infections may invade the digestive system and lead to fistula formation. Tuberculosis is the most common infection associated with these esophageal fistulae. We report here one case of bile duct-duodenal fistula in a female AIDS patient with associated abdominal Mycobacterium tuberculosis infection compromising lymphnodes of the hepatic pedicle where the fistula was found. According to the reviewed literature, this is the third case of bile duct-duodenal fistula associated with abdominal tuberculosis in AIDS patient, and the first where both the fistula and the tuberculosis infection were diagnosed at laparotomy for acute abdomen. Whether the AIDS patient with abdominal pain needs or not a laparotomy to treat an infectious disease is often a difficult matter for the surgeon to decide, as most of the times appropriate medical treatment will bring more benefit.

To estimate esophageal and gastric pH values on an empty stomach and after stimulation of gastric secretion and gastric and duodenal motor-evacuatory activity in patients with gastroesophageal reflux disease (GERD) associated with pathological refluxes, such as gastroesophageal reflux (GER) and duodenogastroesophageal reflux (DGER). The observational cross-sectional study was conducted to investigate and compare the parameters of intraesophageal and intragastric pH metry and peripheral electrogastroenterography in 103 GERD patients with endoscopically positive distal reflux esophagitis in GER and DGER. The patients with GERD developed pathological esophageal refluxes (both GER and DGER) in various degrees of impaired gastric production, from anacidity to hyperacidity. The patients with predominant DGER were found to have gastric hyperacidity and normal acidity slightly less frequently than those with predominant GER. The patients with GERD developing in the presence of predominant GER had moderate gastric stasis with discoordinated antroduodenal propulsion resulting from hypomotor dyskinesia of the stomach and duodenum. When DGER was predominant in the patients with GERD, the signs of gastric stasis and duodenal hyperkinesia were concurrent with discoordinated antroduodenal and duodenojejunal propulsion. The specific features of the esophagogastroduodenal secretory and motor evacuatory disorders found create conditions for the pathological refluxes into the esophagus, which differ in the composition of refluxate.

Esophago-gastro-duodenoscopies with multiple mucosa biopsies were performed before and after irradiation of the mantle field or the spleen pedicle in 13 patients with Hodgkin's disease in stage I and II. For the irradiation the photons of a 4 MeV linear accelerator were applied with focal doses of 40 to 44 Gy. Contrast simulator radiographs were made in order to verify the position within the irradiation field of the organs from which biopsies were taken. In 0/10 patients examined before the irradiation, 0/5 patients examined less than 15 weeks after the irradiation, and 0/12 patients examined 15 weeks or later after the irradiation, histomorphologic investigation of the mucosa of the esophagus showed no pathologic findings. With the same intervals of examination related to irradiation, the gastric mucosa showed a pathologic histomorphology in 1/13, 7/9, and 5/9 patients, respectively, and the duodenal mucosa in 0/13, 5/9, and 2/9 patients, respectively. With the exception of one ulcer in the duodenal bulb, the histopathologic findings as well as the macroscopic findings were neither significant nor characteristic, i.e. not radiospecific. Most of these findings were inflammatory alterations of the mucosa, erosions, and capillarectasies.

Full Text Available Introduction: Gastrointestinal tuberculosis often involves the ileocecal region. Duodenal and gastric tuberculosis found in only 1% of patients suffering from pulmonary tuberculosis with associated HIV infection in non-endemic areas. Duodenal obstruction due to tuberculosis is very rare and needs high index of suspicions for diagnosis. Mostly this entity is suspected on intraoperative findings. In this manuscript we emphasized on ways and means for establishing histopathological diagnosis before starting anti-tubercular treatment in such cases. Method and Material: All patients of suspected gastroduodenal tuberculosis presented with feature of gastric-outlet obstruction managed during Jan 2009 to June 2011 were included in the study. After proper evaluation (routine hematological and biochemical examination, microbiological examination, serological and endoscopic evaluation exploratory laparotomy was done and if there is no mesenteric lymphadenopathy or it is not safe to take biopsy form the diseased duodenum, multiple FNAC were taken from the diseased portion for histopathological and microbiological diagnosis. Result: A total of five patients were treated during this period. The most common presentation was vomiting followed by failure to thrive and weight loss; two patients had abdominal pain. Biopsy of mesenteric lymph node was possible in two cases. FNAC from diseases portion was taken in all cases. FNAC showed granulomas in four cases. Cases where even FNAC finding was non-conclusive on HPE/Microbiology was not subjected to antitubercular drug. Conclusion: Multiple intra-operative FNAC may be taken from the diseased portion of the duodenum to establish the histopathological diagnosis if diagnosis is not established by any other mean.

The number of Africans in Johannesburg presenting with duodenal ulcers has steadily increased over the past 50 years. The characteristics of 105 patients with duodenal ulcer who presented a Baragwanath Hospital were compared with those of matched and unmatched samples of patients without gastrointestinal conditions in the same hospital. Men with duodenal ulcers were found to be significantly better educated than their controls, most had been born in the town, and more of them were employed at higher, though not the highest, educational levels. These data were used to test Susser's proposition that duodenal ulcers are associated with "early urbanisation." Johannesburg blacks with duodenal ulcer did seem to fit the pattern, but the relation between stress and duodenal ulcer remains unclear. PMID:626837

To assess the current management and outcome of perforated duodenal peptic ulcer managed with open repair, a focused analysis was conducted, excluding gastric, traumatic and iatrogenic perforations. A retrospective study of a 6-year period identified 61 patients. Mean age was 59 (range 19-87) years and 33 (54%) were male. Medical history included nonsteroidal anti-inflammatory drugs in 46%, smoking in 30%, atherosclerosis in 26% and excessive alcohol use in 23%. Generalized abdominal tenderness was recorded in 64% of the cases. The mean (SD) C-reactive protein value was 100 (141) g/l and white blood cell count was 12.8 (7.9) E9/l. Plain abdominal X-ray was positive for air in 87% (41/47) and CT scan in 86% (18/21). Four patients (7%) were operated without radiological imaging. There were 31 patients (51%) with a delay of 24 h or more from the start of symptoms to surgery. The mean (SD) delay from admission to surgery was 9 (3) (range 3-12) h. The treatment consisted of open suture repair in 92%, peritoneal lavage in 92%, external drainage in 80% and nasogastric decompression in 92%. The overall hospital mortality and morbidity rates were 11 and 21%, respectively. The duodenal suture leak rate was 7% and intra-abdominal abscess rate was 2%. The majority of patients with perforated duodenal ulcer can be diagnosed with conventional clinical and radiological methods, and treated according to established surgical principles. The mortality and duodenal morbidity rates have remained unchanged for the last decade. Shortening preoperative delay could improve the prognosis.

Full Text Available Abstract Background The prevalence of H. pylori is as high as 60–70% in Chinese population. Although duodenal ulcer and gastric cancer are both caused by H. pylori, they are at opposite ends of the spectrum and as such are considered mutually exclusive. Duodenal ulcer promoting (dupA gene was reported to be associated with duodenal ulcer development. The aim of this study was to determine the prevalence of dupA gene of Helicobacter pylori in patients with various gastroduodenal diseases and to explore the association between the gene and other virulence factors. Methods H. pylori were isolated from gastric biopsies of patients with chronic gastritis, duodenal ulcer (DU, gastric ulcer (GU, or non-cardia gastric carcinoma. The dupA, cagA, vacA, iceA and babA2 genotypes were determined by polymerase chain reaction. Histological features of gastric mucosal biopsy specimens were graded based on the scoring system proposed by the updated Sydney system. IL-1β polymorphism was investigated using restriction fragment length polymorphism. Results Isolates from 360 patients including 133 with chronic gastritis, 101 with DU, 47 with GU, and 79 with non-cardia gastric carcinoma were examined. The dupA gene was detected in 35.3% (127/360 and the prevalence DU patients was significantly greater than that in gastric cancer or GU patients (45.5% vs. 24.1% and 23.4%, P dupA-positive strains had higher scores for chronic inflammation compared to those with dupA-negative strains (2.36 vs. 2.24, p = 0.058. The presence of dupA was not associated with the cagA, vacA, iceA and babA 2 genotypes or with IL-1β polymorphisms. Conclusion In China the prevalence of dupA gene was highest in DU and inversely related to GU and gastric cancer.

Duodenal ulcer promoting (dupA) gene was reported to be associated with duodenal ulcer development. The aim of this study was to determine the prevalence of dupA gene of Helicobacter pylori in patients with various gastroduodenal diseases and to explore the association between the gene and other virulence factors. H. pylori were isolated from gastric biopsies of patients with chronic gastritis, duodenal ulcer (DU), gastric ulcer (GU), or non-cardia gastric carcinoma. The dupA, cagA, vacA, iceA and babA2 genotypes were determined by polymerase chain reaction. Histological features of gastric mucosal biopsy specimens were graded based on the scoring system proposed by the updated Sydney system. IL-1beta polymorphism was investigated using restriction fragment length polymorphism. Isolates from 360 patients including 133 with chronic gastritis, 101 with DU, 47 with GU, and 79 with non-cardia gastric carcinoma were examined. The dupA gene was detected in 35.3% (127/360) and the prevalence DU patients was significantly greater than that in gastric cancer or GU patients (45.5% vs. 24.1% and 23.4%, P dupA-positive strains had higher scores for chronic inflammation compared to those with dupA-negative strains (2.36 vs. 2.24, p = 0.058). The presence of dupA was not associated with the cagA, vacA, iceA and babA 2 genotypes or with IL-1beta polymorphisms. In China the prevalence of dupA gene was highest in DU and inversely related to GU and gastric cancer.

Bypass of the atretic duodenal segment through an anomalous pancreatic ductal system is a rare anomaly described in the literature in only a handful of cases. This case report highlights the importance of considering duodenal atresia and pancreaticobiliary enteric bypass in the differential diagnosis of neonates presenting with partial duodenal obstruction. On ultrasound, the presence of gas in the biliary tree or pancreatic duct should alert the physician to the possibility of duodenal atresia with congenital pancreaticobiliary duct anomalies that allow for bypass of enteric contents, including air, into more distal bowel, thereby creating a gas pattern aptly described as double bubble with distal gas.

Full Text Available Duodenal obstruction due to duodenal atresia occurs in 1 in 10,000 live births and is the most common type of intestinal obstruction in neonates [1–3]. Gastric outlet obstruction in the newborn period from causes other than hypertrophic pyloric stenosis is very uncommon [3]. Potential etiologies include gastric volvulus, antral web, and duplication cysts. Gastric diverticula in the infant is even more rare, with only a few case reports published, and only one describes a gastric diverticulum in the presence of a duodenal atresia [4–8]. In this report, we describe the first case of a gastric outlet obstruction due to a gastric diverticulum in the presence of duodenal atresia.

Purpose: Improving local control is critical to improving survival and quality of life for patients with locally advanced unresectable pancreatic cancer (LAPC). However, previous attempts at radiation dose escalation have been limited by duodenal toxicity. In order to guide future studies, we analyzed the clinical and dosimetric factors associated with duodenal toxicity in patients undergoing fractionated chemoradiation for LAPC. Methods and Materials: Medical records and treatment plans of 106 patients with LAPC who were treated with chemoradiation between July 2005 and June 2010 at our institution were reviewed. All patients received neoadjuvant and concurrent chemotherapy. Seventy-eight patients were treated with conventional radiation to 50.4 Gy in 28 fractions; 28 patients received dose-escalated radiation therapy (range, 57.5-75.4 Gy in 28-39 fractions). Treatment-related toxicity was graded according to Common Terminology Criteria for Adverse Events, version 4.0. Univariate and multivariate analyses were performed to assess prognostic influence of clinical, pathologic, and treatment-related factors by using Kaplan-Meier and Cox regression methods. Results: Twenty patients had treatment-related duodenal toxicity events, such as duodenal inflammation, ulceration, and bleeding. Four patients had grade 1 events, 8 had grade 2, 6 had grade 3, 1 had grade 4, and 1 had grade 5. On univariate analysis, a toxicity grade ≥2 was associated with tumor location, low platelet count, an absolute volume (cm{sup 3}) receiving a dose of at least 55 Gy (V{sub 55} {sub Gy} > 1 cm{sup 3}), and a maximum point dose >60 Gy. Of these factors, only V{sub 55} {sub Gy} ≥1 cm{sup 3} was associated with duodenal toxicity on multivariate analysis (hazard ratio, 6.7; range, 2.0-18.8; P=.002). Conclusions: This study demonstrates that a duodenal V{sub 55} {sub Gy} >1 cm{sup 3} is an important dosimetric predictor of grade 2 or greater duodenal toxicity and establishes it as a

Full Text Available The high prevalence of the pathology of major duodenal papilla in patients with gallstone disease, the difficulties of diagnosis and treatment determine the relevance of the study. The purpose is to study the morphological features of the major duodenal papilla in patients with cholelithiasis. Material and methods. During autopsies, selection of fragments of major duodenal papilla from 30 dead was performed. The main group consisted of autopsy specimens (n = 15 from the dead, which had stones in the gallbladder in the absence of signs of inflammation of the walls of the gallbladder and bile ducts. Biomaterial samples (n = 15 from the dead, which had no stones and signs of inflammation of the biliary system, were included in the control group. To study the severity of the stromal component, the Mason’s trichrome and the Van Gieson’s stains were used. Light microscopy was carried out using a light microscope Axioplan 2 (Carl Zeiss - Germany using x10, x20, x40, x100 lenses and x10 eyepiece. For a quantitative assessment of the severity of sclerotic changes, we conducted a morphometric study of preparations stained with picrofuchsin accordimg to Van Gieson. The area of the stromal component was calculated in the resulted images in 5 fields of view under magnification of x200 using the medical software for analysis and processing of digital images ImageJ, initiated by W.

The management of pancreatic and duodenal trauma has moved away from complex reconstructive procedures to simpler methods in keeping with the trend towards organ-specific, damage control surgery. A retrospective case note review was undertaken over a 30-month period to evaluate a simplified protocol for the management of these injuries. Of 100 consecutive patients there were 51 with pancreatic injury, 30 with a duodenal injury and 19 with combined pancreaticoduodenal trauma. Overall mortality was 18.0%, with a late mortality (after 24 h) of 9.9%. This is comparable to previous studies. Morbidity from abscesses, fistulas and anastomotic breakdown was acceptably low. The concept of staged laparotomy can be successfully applied to wounds of the pancreas and duodenum. Debridement of devitalized tissue and drainage can be employed for most cases of pancreatic trauma. Most duodenal injuries can be managed with debridement and primary repair. Temporary exclusion and reoperation should be employed for unstable patients.

Retrospective analysis of gastro-duodenal bleeding (GDB report forms was performed. Pts admitted to the department of internal diseases of Saratov regional clinical hospital from 1999 to 2004 were included. 354 cases of GDB were recorded ( 282 from 1999 to 2001 and 72 from 2002 to 2004. Cause ofbleeding, influence of NSAID administration on appearance and relapse ofbleeding, source ofbleeding and pt management were assessed. NSAJD administration was considered trigger factor of GDB in 24% in 1999-2001 and in 18% in 2002-2004. The results of the study show some tendency to decrease of NSAID- induced gastropathy frequency among causes of GDB. The main risk factors ofbleeding during NSAID treatment were age of more than 30 years, ulcer history, the first month of NSAID administration. GDB frequency did not depend on regularity of treatment and NSAID dosage.

1986-01-01

The occurrence of dyspeptic symptoms has previously been correlated with the shape of the duodenal loop in patients with X-ray-negative dyspepsia. An abnormal duodenal loop was associated with a significantly higher incidence of symtoms provoked by meals, vomiting, regurgitations, heartburn, and the irritable bowel syndrome. 89% of these patients (26 patients with a normal duodenal loop and 39 patients with abnormal duodenal loop) were available for a 5-year follow-up study of symptomatic outcome. The incidence of symptoms provoked by meals was still significantly higher in patients with an abnormal duodenal loop, and there was also a significant difference concerning symptomatic outcome. Approximately 75% of the patients with a normal duodenal loop had improved, and 25% had unchanged clinical conditions. Approximately 50% of the patients with an abnormal duodenal loop had improved, and 50% had an unchanged or even deteriorated clinical condition.

Diagnosis and classification of pancreatic and duodenal injuries in emergency radiology.

Pancreatic and duodenal injuries after blunt abdominal trauma are rare; however, delays in diagnosis and treatment can significantly increase morbidity and mortality. Multidetector computed tomography (CT) has a major role in early diagnosis of pancreatic and duodenal injuries. Detecting the often subtle signs of injury with whole-body CT can be difficult because this technique usually does not include a dedicated protocol for scanning the pancreas. Specific injury patterns in the pancreas and duodenum often have variable expression at early posttraumatic multidetector CT: They may be hardly visible, or there may be considerable exudate, hematomas, organ ruptures, or active bleeding. An accurate multidetector CT technique allows optimized detection of subtle abnormalities. In duodenal injuries, differentiation between a contusion of the duodenal wall or mural hematoma and a duodenal perforation is vital. In pancreatic injuries, determination of involvement of the pancreatic duct is essential. The latter conditions require immediate surgical intervention. Use of organ injury scales and a surgical classification adapted for multidetector CT enables classification of organ injuries for trauma scoring, treatment planning, and outcome control. In addition, multidetector CT reliably demonstrates potential complications of duodenal and pancreatic injuries, such as posttraumatic pancreatitis, pseudocysts, fistulas, exudates, and abscesses.

1988-01-01

Celiac disease (CD) is the most common form of malabsorption in childhood when it presents with diarrhea and groeth failure, a jejunal biopsy is considered the first diagnostic investigation by some authors. In adulthood, clinical symptoms of CD may mimik several different disease, such as peptic ulcer and IBS, and the first diagnostic investigation is an upper GI series. Radiological features of duodenum and small bowel were evaluated in twenty patients with adult onset celiac disease. Sign of duodenitis such as thickened folds, mucosal nodules, dilatation of duodenum and erosions were observed in 19 out of 20 patients (95%); particulary, thickened folds in 71 (85%), nodularity in 16 (80%), duodenal dilatation in 12 (60%) and erosions in 4 (20%). In celiac disease the lesions are more severe in the upper part of small bowel, and duodenitis may be the unique sign of CD. Duodenitis may be part of a disease involving the entire small bowel; so, a duodenitis observed in the upper gastrointestinal tract requires the study of the entire small bowel - which seems to be very important in the case of celiac disease

There is ongoing debate about the management of severe duodenal injuries (SDIs), and earlier studies have recommended pyloric exclusion. The objective of this study was to compare primary repair with pyloric exclusion to examine if primary repair can be safely used in SDIs. The medical records of 193 consecutive patients who were admitted between August 1992 and January 2004 with duodenal injuries were reviewed. After excluding early deaths (n = 50), low-grade duodenal injuries (n = 81), and pancreatoduodenectomies for catastrophic trauma (n = 12), a total of 50 patients with SDIs (grade III, IV, or V) were analyzed. Primary repair (PR--simple duodenorrhaphy or resection and primary anastomosis) was performed in 34 (68%) and pyloric exclusion (PE) in 16 (32%). Characteristics and outcomes of these two groups were compared. PE and PR patients were similar for age, injury severity score, abdominal abbreviated injury score, physiologic status on admission, time to operation, and most abdominal organs injured. PE patients had more pancreatic injuries (63% vs. 24%, p duodenum (79% vs. 42%, p = 0.02), and a nonsignificant trend toward more grade IV and V injuries (37% vs. 18%, p = 0.11). There was no difference in morbidity (including complications specific to the duodenal repair), mortality, and intensive care unit and hospital length of stay between the two groups. Pyloric exclusion is not necessary for all patients with SDIs, as previously suggested. Selected SDI patients can be safely managed by simple primary repair.

Patients with pancreatic and/or duodenal trauma often have a high incidence of infectious complications. In this study we attempted to find the most important risk factors for these infections. A retrospective review of the records of 167 patients seen over 7 years (1989 through 1996) at an urban Level I trauma center for injury to the duodenum and/or pancreas was performed. Fifty-nine patients (35%) had isolated injury to the duodenum (13 blunt, 46 penetrating), 81 (49%) had isolated pancreatic trauma (18 blunt, 63 penetrating), and 27 (16%) had combined injuries (two blunt, 25 penetrating). The overall mortality rate was 21 per cent and the infectious morbidity rate was 40 per cent. The majority of patients had primary repair and/or drainage as treatment of their injuries. Patients with pancreatic injuries (alone or combined with a duodenal injury) had a much higher infection rate than duodenal injuries. The patients with duodenal injuries had significantly lower penetrating abdominal trauma indices, number of intra-abdominal organ injuries, and incidence of hypothermia. On multivariate analysis independent factors associated with infections included hypothermia and the presence of a pancreatic injury. Although injuries to the pancreas and duodenum often coexist it is the pancreatic injury that contributes most to the infectious morbidity.

Effect of tyrosine administration on duodenal ulcer induced by cysteamine in the rat

International Nuclear Information System (INIS)

Oishi, T.; Szabo, S.

1987-01-01

Duodenal ulcers were produced by administering cysteamine to rats. Pretreatment with the catecholamine precursor, L-tyrosine (40 mg/100 g i.p. for 5 days), decreased the intensity of duodenal ulcers induced by cysteamine. Equimolar doses of tyrosine methyl ester (51.2 mg/100 g i.p. or s.c.) were equally effective in reducing ulcer intensity. Other amino acids (i.e., alanine, aspartic acid, glutamic acid, glycine, leucine, lysine, tryptophan and valine) did not prevent experimental duodenal ulcers. Coadministration of other large neutral amino acids (e.g., leucine and valine) that compete with tyrosine for uptake into the brain did not inhibit the effect of tyrosine on duodenal ulcers induced by cysteamine. Gastric, duodenal and brain dopamine concentrations were increased 1 hr after the injection of tyrosine methyl ester (25.6 mg/100 g s.c.). These results suggest that the effect of tyrosine on duodenal ulcer induced by cysteamine may be mediated by changes in gastrointestinal dopamine metabolism

Full Text Available Duodenal duplication cysts are rare congenital lesions. Their presentation is often non-specific and physical examination and laboratory studies usually reveal no abnormal findings. The diagnosis of duodenal duplication cysts can thus be challenging and relies on ultrasonography, barium swallow, contrast enhanced computed tomography (CT, magnetic resonance imaging (MRI, and magnetic resonance cholangiopancreatography (MRCP. The management of duodenal duplication cyst is surgical. Laparotomy is usually necessary, and complete resection is the management goal. Subtotal excision with stripping of the mucosa due to close involvement of the pancreatobiliary tree, and endoscopic resection have Duodenal duplication cysts are rare congenital lesions usually diagnosed in infancy, although they may present in adulthood. Prenatal diagnosis is difficult, and postnatal diagnosis relies on ultrasonography, barium swallow, contrast-enhanced computerized tomography, magnetic resonance imaging (MRI, and magnetic resonance cholangiopancreatography. A female newborn was diagnosed with an abdominal cyst (size around 6 ×; 5 × 4 cm at gestational age (GA 24 weeks, by regular prenatal examination. After her birth at GA 37 weeks, we performed abdominal ultrasonography and MRI, but there was no definite diagnosis. The usual management of an abdominal cyst involves resection by laparotomy (requiring a large incision or laparoscopy (requiring several small incisions. We performed an exploratory trans-umbilical minimal laparotomy excision for surgery, and the pathology revealed duodenal duplication. In our case, there was no recurrence of the cyst after 18 months follow-up, and the operation scar was almost undetectable. Trans-umbilical minimal laparotomy excision may be considered as an alternative choice for the management of abdominal and duodenal duplication cysts.

Full Text Available Abstract Background The aim of this report was to describe duodenal obstruction caused by a rubber foreign body in a cow. Case Presentation The clinical, biochemical and ultrasonographic findings in a five-year-old Swiss Braunvieh cow with duodenal ileus caused by a calf feeding nipple are described. The main clinical signs were anorexia, ruminal tympany, decreased faecal output and abomasal reflux syndrome. Ultrasonographic examination revealed reticular hyperactivity and a dilated duodenum. A diagnosis of duodenal ileus was made and the cow underwent right-flank laparotomy, which revealed a dilation of the cranial part of the duodenum because of obstruction by a pliable foreign body. This was identified via enterotomy as a calf feeding nipple. The cow was healthy at the time of discharge four days after surgery and went on to complete a successful lactation. Conclusions To our knowledge, this is the first description of duodenal obstruction by a calf feeding nipple. This is an interesting case, which broadens the spectrum of the causes of duodenal ileus, which is usually caused by obstruction of the duodenum by a phytobezoar.

Pancreatic heterotopia (PH) is defined as ectopic pancreatic tissue outside the normal pancreas and its vasculature and duct system. Most frequently, PH is detected incidentally by histopathological examination. The aim of the present study was to analyze a large single-center series of duodenal PH with respect to the clinical presentation. A prospective pancreatic database was retrospectively analyzed for cases of PH of the duodenum. All pancreatic and duodenal resections performed between January 2000 and October 2015 were included and screened for histopathologically proven duodenal PH. PH was classified according to Heinrich's classification (Type I acini, ducts, and islet cells; Type II acini and ducts; Type III only ducts). A total of 1274 pancreatic and duodenal resections were performed within the study period, and 67 cases of PH (5.3%) were identified. The respective patients were predominantly male (72%) and either underwent pancreatoduodenectomy (n = 60); a limited pancreas resection with partial duodenal resection (n = 4); distal pancreatectomy with partial duodenal resection (n = 1); total pancreatectomy (n = 1); or enucleation (n = 1). Whereas 65 patients (83.5%) were asymptomatic, 11 patients (18.4%) presented with symptoms related to PH (most frequently with abdominal pain [72%] and duodenal obstruction [55%]). Of those, seven patients (63.6%) had chronic pancreatitis in the heterotopic pancreas. The risk of malignant transformation into adenocarcinoma was 2.9%. PH is found in approximately 5% of pancreatic or duodenal resections and is generally asymptomatic. Chronic pancreatitis is not uncommon in heterotopic pancreatic tissue, and even there is a risk of malignant transformation. PH should be considered for the differential diagnosis of duodenal lesions and surgery should be considered, especially in symptomatic cases.

Duodenal Wedge Resection for Large Gastrointestinal Stromal Tumour Presenting with Life-Threatening Haemorrhage

2013-01-01

Full Text Available Background. Duodenal gastrointestinal stromal tumours (GISTs are an uncommon malignancy of the gastrointestinal (GI tract. We present a case of life-threatening haemorrhage caused by a large ulcerating duodenal GIST arising from the third part of the duodenum managed by a limited duodenal wedge resection. Case Presentation. A 61-year-old patient presented with acute life-threatening gastrointestinal bleeding. After oesophagogastroduodenoscopy failed to demonstrate the source of bleeding, a 5 cm ulcerating exophytic mass originating from the third part of the duodenum was identified at laparotomy. A successful limited wedge resection of the tumour mass was performed. Histopathology subsequently confirmed a duodenal GIST. The patient remained well at 12-month followup with no evidence of local recurrence or metastatic spread. Conclusion. Duodenal GISTs can present with life-threatening upper GI haemorrhage. In the context of acute haemorrhage, even relatively large duodenal GISTs can be treated by limited wedge resection. This is a preferable alternative to duodenopancreatectomy with lower morbidity and mortality but comparable oncological outcome.

Purpose: This study was designed to evaluate retrospectively the safety and efficacy of the percutaneous management of duodenal stump leakage with a Foley catheter after subtotal gastrectomy. Methods: Ten consecutive patients (M:F = 9:1, median age: 64 years) were included in this retrospective study. The duodenal stump leakages were diagnosed in all the patients within a median of 10 days (range, 6–20). At first, the patients underwent percutaneous drainage on the day of or the day after confirmation of the presence of duodenal stump leakage, and then the Foley catheters were replaced at a median of 9 days (range, 6–38) after the percutaneous drainage. Results: Foley catheters were placed successfully in the duodenal lumen of all the patients under a fluoroscopic guide. No complication was observed during and after the procedures in all the patients. All of the patients started a regular diet 1 day after the Foley catheter placement. The patients were discharged at a median of 7 days (range, 5–14) after the Foley catheter placement. The catheters were removed in an outpatient clinic 10–58 days (median, 28) after the Foley catheter placement. Conclusions: Fluoroscopy-guided percutaneous Foley catheter placement may be a safe and effective treatment option for postoperative duodenal stump leakage and may allow for shorter hospital stays, earlier oral intake, and more effective control of leakage sites

Full Text Available CONTEXT: Intestinal parasites induce detectable histopathological changes, which have been studied in groups with known diagnosis of parasitic disease. There is no available study with a larger base without previous diagnosis. OBJECTIVE: To describe clinical and histopathological findings of parasitosis diagnosed by endoscopic biopsy in patients submitted to upper digestive endoscopy. METHODS: Recorded biopsies archive at "Complexo Hospitalar Professor Edgar Santos" , a general teaching Hospital in the state of Bahia, Northeast Brazil, from January 1995 to January 2009, were reviewed. One thousand ten duodenal biopsy reports were found. Reports positive for parasites had their specimens reviewed and photographed. All blocks of biopsy selected as case were retrieved and reviewed by an experienced pathologist. Clinical, laboratorial and endoscopic data were collected. RESULTS: Eleven biopsies showed parasites, including cases of Cryptosporidium sp. and Strongyloides stercoralis. Vomiting (91%, abdominal pain (78%, diarrhea (78% and weight loss (78% were usual symptoms. Seventy-five percent had duodenal mucosa changes on endoscopy, while 25% have no changes. Anemia and low serum albumin were important laboratorial data. HIV infection association was observed. Villus atrophy and reactive epithelium were usual in Strongyloides cases. CONCLUSIONS: No endoscopic or histopathologic finding was pathognomonic. One percent of duodenal endoscopic biopsies showed parasites.

Endoscopic resection of duodenal non-lifting adenomas and subepithelial tumors is challenging and harbors a significant risk of adverse events. We report on a novel technique for duodenal endoscopic full-thickness resection (EFTR) by using an over-the-scope device. Data of 4 consecutive patients who underwent duodenal EFTR were analyzed retrospectively. Main outcome measures were technical success, R0 resection, histologic confirmation of full-thickness resection, and adverse events. Resections were done with a novel, over-the-scope device (full-thickness resection device, FTRD). Four patients (median age 60 years) with non-lifting adenomas (2 patients) or subepithelial tumors (2 patients) underwent EFTR in the duodenum. All lesions could be resected successfully. Mean procedure time was 67.5 minutes (range 50-85 minutes). Minor bleeding was observed in 2 cases; blood transfusions were not required. There was no immediate or delayed perforation. Mean diameter of the resection specimen was 28.3 mm (range 22-40 mm). Histology confirmed complete (R0) full-thickness resection in 3 of 4 cases. To date, 2-month endoscopic follow-up has been obtained in 3 patients. In all cases, the over-the-scope clip was still in place and could be removed without adverse events; recurrences were not observed. EFTR in the duodenum with the FTRD is a promising technique that has the potential to spare surgical resections. Modifications of the device should be made to facilitate introduction by mouth. Prospective studies are needed to further evaluate efficacy and safety for duodenal resections. Copyright © 2015 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

Full Text Available Duodenal ulcer is an uncommonly diagnosed entity in children. H. pyloriinfection, blood group ‘O’ or secondary to medications like non steroidal anti-infl ammatory drugs (NSAID and corticosteroids or physiological stress in burns, head injury and mucosal ischemia are implicated as risk factors for their causation. The diagnosis is usually overlooked because of vague and variable symptoms and remote index of suspicion accounted for their low incidence in children. Undiagnosed or mistreated perforations may carry high morbidity and mortality. We report a successfully treated 41/2 year old male child who presented with features of perforation peritonitis and was incidentally found to have a perforated duodenal ulcer.

The intestinal barrier is made up of epithelial cells and intercellular junctional complexes to regulate epithelial ion transport and permeability. Dopamine (DA) is able to promote duodenal epithelial ion transport through D1-like receptors, which includes subtypes of D 1 (D 1 R) and D 5 (D 5 R), but whether D1-like receptors influence the duodenal permeability is unclear. FITC-dextran permeability, short-circuit current (I SC ), Western blot, immunohistochemistry and ELISA were used in human D 5 R transgenic mice and hyperendogenous enteric DA (HEnD) rats in this study. Dopamine induced a downward deflection in I SC and an increase in FITC-dextran permeability of control rat duodenum, which were inhibited by the D1-like receptor antagonist, SCH-23390. However, DA decreased duodenal transepithelial resistance (TER), an effect also reversed by SCH-23390. A strong immunofluorescence signal for D 5 R, but not D 1 R, was observed in the duodenum of control rat. In human D 5 R knock-in transgenic mice, duodenal mucosa displayed an increased basal I SC with high FITC-dextran permeability and decreased TER with a lowered expression of tight junction proteins, suggesting attenuated duodenal barrier function in these transgenic mice. D 5 R knock-down transgenic mice manifested a decreased basal I SC with lowered FITC-dextran permeability. Moreover, an increased FITC-dextran permeability combined with decreased TER and tight junction protein expression in duodenal mucosa were also observed in HEnD rats. This study demonstrates, for the first time, that DA enhances duodenal permeability of control rat via D 5 R, which provides new experimental and theoretical evidence for the influence of DA on duodenal epithelial barrier function. © 2016 Scandinavian Physiological Society.

Identification of a disease-specific H pylori virulence factors predictive of the outcome of infection remains unachieved. We used the polymerase chain reaction and Southern blot to compare the presence of 14 vir homologue genes with clinical presentation of H pylori infection, mucosal histology, and mucosal interleukin (IL)-8 levels. We examined 500 H pylori strains from East Asia and South America, including 120 with gastritis, 140 with duodenal ulcer (DU), 110 with gastric ulcer (GU), and 130 with gastric cancer. Only 1 gene that encompassed both jhp0917 and jhp0918 called dupA (duodenal ulcer promoting gene) was associated with a specific clinical outcome. dupA was present in 42% of DU vs. 21% of gastritis (adjusted odds ratio [OR] = 3.1, 95% confidence interval [CI]: 1.7-5.7). Its presence was also associated with more intense antral neutrophil infiltration and IL-8 levels and was a marker for protection against gastric atrophy, intestinal metaplasia, and gastric cancer (OR for gastric cancer = 0.42, 95% CI: 0.2-0.9 compared with gastritis). In vitro studies in gastric epithelial cells using dupA -deleted and -complemented mutants showed that the dupA plays roles in IL-8 production, in activation of transcription factors responsible for IL-8 promoter activity, and in increased survivability at low pH. dupA is a novel marker associated with an increased risk for DU and reduced risk for gastric atrophy and cancer. Its association with DU-promoting and -protective effects against atrophy/cancer was evident in both Asian and Western countries.

THE CLINICAL MANIFESTATIONS AND COURSE OF DUODENAL ULCER DISEASE AFTER PERFORATED ULCER

Full Text Available Objective: to compare clinical manifestations, course, mental status in duodenal ulcer (DU patients with a history of perforated ulcer and its uncomplicated course.Subjects and methods. One hundred and thirteen patents with DU were examined. Group 1 included 61 patients with uncomplicated DUand Group 2 comprised 52 patients with a history of perforated ulcer. A comparison group consisted of 20 patients who had undergone laparotomy. Physical and mental status examinations, esophagogastroduodenoscopy (EGDS, and 24-hour pH-metry were performed.Results. Classical pain syndrome was observed in 75 % of the patients with uncomplicated DU. Prior to perforation, the pain and dyspeptic syndromes were distinguished only by a significantly lower degree in Group 2; following perforation, the pain syndrome was recorded more frequently, it was more extensive, meal-unrelated, and similar to that in the patients who had undergone laparotomy and had diminished appetite (36.5 %. EGDS showed that the complicated course was accompanied by the significantly higher incidence of erosive esophagitis (21.2 %, gastritis (51.9 %, duodenitis (25.0 %, multiple ulcers (28.8 %, and larger ulcers. 24-hour pH-metry indicated that the level of hyperacidity in Group 2 was higher and the circadian intragastric pH variations were less marked than those in uncomplicated DU. The patients with a history of perforated ulcer showed a high rate of anxiety and depressive changes. Conclusion. In complicated DU, marked monotonic hyperacidity causes common erosive-ulcerative lesions in the gastroduodenal area in relatively mild pain syndrome, late referrals, and long-term ulcer healing. After perforation followed by wound closure, the pain and dyspeptic syndromes become more pronounced, which is associated with anxiety and depressive changes in the mental status, as well as with early referrals and less healing time.

showed positive margins (R1). No patient developed local recurrence during follow-up. The one patient who underwent pancreatoduodenectomy died due to progressive disease with hepatic metastasis but without evidence of local recurrence. Another patient died in complete remission due to cardiac disease. Seven of the nine patients are alive disease-free. CONCLUSION: In patients with duodenal GIST, limited surgical resection with microscopically negative margins, but also with microscopically positive margins, lead to very good local and systemic disease-free survival.

Labelling indices after 3H-thymidine incorporation during organ culture of duodenal mucosa in coeliac disease

International Nuclear Information System (INIS)

Fluge, G.; Aksnes, L.

1980-01-01

Incorporation of 3 H-thymidine during organ culture of duodenal biopsy specimens from 34 coeliac and 10 non-coeliac patients was studied by autoradiography. High labelling indices were found in flat, coeliac mucosas. Gluten fractions, which provoked histological deterioration during culture, induced labelling of a greater proportion of crypt cells and higher migration rate than parallelly cultured specimens on gluten-free medium. No influence on clypt cell kinetics could be observed after culture with gluten fractions incapable of producing histological damage or with alpha-lactalbumin. In coeliac remission mucosas, labelling indices were at the same level as in non-coeliac biopsis, and no significant effects of gluten were observed. Autoradiography seems to be a fairly sensitive and reliable determinant of gluten toxicity by organ culture in coeliac desease and should supplement the histological appraisal of the biopsies. The increment of labelling indices provoked by gluten exposure seemed not merely to be a concequence of increased desquamation of cells from the biopsy surface but could imply a direct influence of gluten on crypt cell kinetics in coeliac disease.

Full Text Available Duodenal injury following laparoscopic cholecystectomy is rare complications with catastrophic sequelae. Most injuries are attributed to thermal burns with electrocautery following adhesiolysis and have a delayed presentation requiring surgical intervention. We present a case of a 47-year-old gentleman operated on for laparoscopic cholecystectomy with a bilious drain postoperatively; for which an ERC was done showing choledocholithiasis with cystic duct stump blow-out and a drain in the duodenum suggestive of an iatrogenic duodenal injury. He was managed conservatively like a duodenal fistula and recovered without undergoing any intervention.

Complex fistulas of the duodenum and biliary tree are severe complications of gastric surgery. The association of duodenal and major biliary fistulas occurs rarely and is a major challenge for treatment. They may occur during virtually any kind of operation, but they are more frequent in cases complicated by the presence of difficult duodenal ulcers or cancer, with a mortality rate of up to 35%. Options for treatment are many and range from simple drainage to extended resections and difficult reconstructions. Conservative treatment is the choice for well-drained fistulas, but some cases require reoperation. Very little is known about reoperation techniques and technical selection of the right patients. We present the case of a complex iatrogenic duodenal and biliary fistula. A 42-year-old Caucasian man with a diagnosis of postoperative peritonitis had been operated on 3 days earlier; an antrectomy with a Roux-en-Y reconstruction for stenotic peptic disease was performed. Conservative treatment was attempted with mixed results. Two more operations were required to achieve a definitive resolution of the fistula and related local complications. The decision was made to perform a pancreatoduodenectomy with subsequent reconstruction on a double jejunal loop. The patient did well and was discharged on postoperative day 17. In our experience pancreaticoduodenectomy may be an effective treatment of refractory and complex iatrogenic fistulas involving both the duodenum and the biliary tree.

CpG island methylator phenotype (CIMP) has been found in multiple precancerous and cancerous lesions, including colorectal adenomas, colorectal cancers, and duodenal adenocarcinomas. There are no reports in the literature of a relationship between CIMP status and clinicopathologic features of sporadic duodenal adenomas. This study sought to elucidate the role of methylation in duodenal adenomas and correlate it with KRAS and BRAF mutations. CIMP+ (with more than 2 markers methylated) was seen in 33.3% of duodenal adenomas; 61% of these CIMP+ adenomas were CIMP-high (with more than 3 markers methylated). Furthermore, CIMP+ status significantly correlated with older age of patients, larger size and villous type of tumor, coexistent dysplasia and periampullary location. MLH1 methylation was seen in 11.1% of duodenal adenomas and was significantly associated with CIMP+ tumors, while p16 methylation was an infrequent event. KRAS mutations were frequent and seen in 26.3% of adenomas; however, no BRAF mutations were detected. Furthermore, CIMP-high status was associated with larger size and villous type of tumor and race (non-white). These results suggest that CIMP+ duodenal adenomas may have a higher risk for developing malignancy and may require more aggressive management and surveillance.

A new prognostic scoring system for perforation peritonitis secondary to duodenal ulcers

International Nuclear Information System (INIS)

Nomani, A.Z.; Qureshi, M.S.

2014-01-01

Objective: To identify prognostic factors for perforated duodenal ulcers and to devise and assess a new scoring system. Methods: The observational prospective study was conducted at the Mayo Hospital, Lahore in two phases: from March 2010 to September 2011; and from October 2011 to July 2012. It included patients with duodenal ulcer perforation who were observed for identifying factors predicting 30-day prognosis. Each of the predictive factor was given a score based on its severity to devise a new scoring system. Chi-square was used for univariate analysis. Multivariate analysis was done using forward stepwise regression. Accuracy of the new scoring system was calculated using receiver operating curve analysis and its validity was evaluated in the second phase of the study. Results: Predictors of poor prognosis included multiple gut perforations, size of largest perforation >0.5cm, amount of peritoneal fluid >1000ml, simple closure, development of complications, post-operative systemic septicaemia and winter/autumn season of presentation. Overall 30-day mortality rate was 32.3% (n=32) and morbidity rate was 21.2% (n=21). The mean score was higher in the ones with poor prognosis (p=0.001). Similarly, the mean score was greater in those with grave prognosis (p=0.001). The scoring system had an overall sensitivity of 85.12% and specificity of 80.67% and was favourably comparable to other scoring systems. Conclusion: The new scoring system is a useful tool in predicting 30-day prognosis for perforated duodenal ulcers in acid peptic disease. (author)

The duodenum senses nutrients to maintain energy and glucose homeostasis, but little is known about the signaling and neuronal mechanisms involved. We tested whether duodenal activation of adenosine 3',5'-cyclic monophosphate (cAMP)-dependent protein kinase A (PKA) is sufficient and necessary for cholecystokinin (CCK) signaling to trigger vagal afferent firing and regulate glucose production. In rats, we selectively activated duodenal PKA and evaluated changes in glucose kinetics during the pancreatic (basal insulin) pancreatic clamps and vagal afferent firing. The requirement of duodenal PKA signaling in glucose regulation was evaluated by inhibiting duodenal activation of PKA in the presence of infusion of the intraduodenal PKA agonist (Sp-cAMPS) or CCK1 receptor agonist (CCK-8). We also assessed the involvement of a neuronal network and the metabolic impact of duodenal PKA activation in rats placed on high-fat diets. Intraduodenal infusion of Sp-cAMPS activated duodenal PKA and lowered glucose production, in association with increased vagal afferent firing in control rats. The metabolic and neuronal effects of duodenal Sp-cAMPS were negated by coinfusion with either the PKA inhibitor H89 or Rp-CAMPS. The metabolic effect was also negated by coinfusion with tetracaine, molecular and pharmacologic inhibition of NR1-containing N-methyl-d-aspartate (NMDA) receptors within the dorsal vagal complex, or hepatic vagotomy in rats. Inhibition of duodenal PKA blocked the ability of duodenal CCK-8 to reduce glucose production in control rats, whereas duodenal Sp-cAMPS bypassed duodenal CCK resistance and activated duodenal PKA and lowered glucose production in rats on high-fat diets. We identified a neural glucoregulatory function of duodenal PKA signaling. Copyright © 2012 AGA Institute. Published by Elsevier Inc. All rights reserved.

The diagnosis of intestinal lymphangiectasia (IL) has been associated with characteristic duodenal mucosal changes. However, the sensitivity and specificity of the endoscopic duodenal mucosal appearance for the diagnosis of IL are not reported. To evaluate the utility of endoscopic images of the duodenum for diagnosis of IL. Endoscopic appearance of the duodenal mucosal might predict histopathologic diagnosis of IL with a high degree of sensitivity and specificity. 51 dogs that underwent upper gastrointestinal (GI) endoscopy and endoscopic biopsies. Retrospective review of images acquired during endoscopy. Dogs were included if adequate biopsies were obtained during upper GI endoscopy and digital images were saved during the procedure. Images were assessed for the presence and severity of IL. Using histopathology as the gold standard, the sensitivity and specificity of endoscopy for diagnosing IL were calculated. Intestinal lymphangiectasia (IL) was diagnosed in 25/51 dogs. Gross endoscopic appearance of the duodenal mucosa had a sensitivity and specificity (95% confidence interval) of 68% (46%, 84%) and 42% (24%, 63%), respectively for diagnosis of IL. Endoscopic images in cases with lymphopenia, hypocholesterolemia, and hypoalbuminemia had a sensitivity of 80%. Endoscopic duodenal mucosa appearance alone lacks specificity and has only a moderate sensitivity for diagnosis of IL. Evaluation of biomarkers associated with PLE improved the sensitivity; however, poor specificity for diagnosis of IL supports the need for histopathologic confirmation.

Mcfarlane, Michael; Liu, B; Nwokolo, C

2018-04-01

Domperidone is thought to accelerate gastric emptying via D2 receptor antagonism at the gastro-oesophageal and gastro-duodenal junctions. Listed in the BNF as a prokinetic anti-emetic, it has been used in video capsule endoscopy (VCE) to accelerate capsule delivery to the small intestine. We audited VCEs performed at UHCW from 2011, when as standard practice, domperidone was given pre-VCE, to 2012, after its discontinuation due to doubts about its effectiveness. Thirty-one patients received oral domperidone 20 mg pre-VCE. Thirty-three patients underwent VCE without domperidone pre-treatment. After 2 h, if the capsule remained intra-gastric, gastroscopy-assisted duodenal delivery was performed. Data was analysed using Mann-Whitney testing. Median oro-duodenal transit was 13 and 30 min in the untreated and domperidone groups, respectively (p = 0.01). Median oro-caecal transit was 242 and 267 min in the untreated and domperidone groups, respectively (p = 0.02). No difference in duodenal-caecal transit was seen (p = 0.60). Six percent of untreated and 13% of domperidone VCEs required gastroscopy-assisted duodenal capsule delivery (p = 0.65). Unexpectedly domperidone delayed VCE gastric transit. Most studies on domperidone prokinetic effects have been in diabetic gastroparesis, demonstrating that domperidone can achieve good symptomatic relief, but with mixed results for gastric emptying. Our study suggests that any antiemetic effects of domperidone are not mediated through accelerated gastric transit.

Full Text Available A submucosal lymphangioma is a rare pathology in the alimentary tract. It is a benign entity of the lymphatic system. A duodenal lymphangioma is extremely rare and has an unknown etiology. Clinical and laboratory findings are nonspecific, and they are incidentally found by endoscopy and their treatment is surgical excision. Small lesions are often asymptomatic. Recently, the authors experienced a 62-year-old man, who had a duodenal lymphangioma, showing gastric outlet obstruction symptoms. A multidetector computed tomography abdomen study revealed a single submucosal cystic lesion in second part of duodenum. The lesion was successfully excised after Whipple′s procedure. Histopathology confirmed the diagnosis of lymphangioma.

In this retrospective study a total of 105 patients, suspected of having CD because of extra-intestinal symptoms and showing serum tissue transglutaminase antibody (anti-tTG) and anti-endomysial antibody (EMA) measurements and HLA genotyping, were considered for the final analysis (33 boys and 72 girls; age range 1.5-17.6 years). Histological findings confirmed diagnosis of CD in 97 (92.4%) patients. Forty-one patients (39%) showed anti-tTG >10 times normal values, positive EMA and positive HLA-DQ2/DQ8 (positive TT). All of them had a diagnosis of CD, therefore there were no false positive cases. Sixty-four patients were negative for the TT. In eight cases, CD was ruled out and these were considered true negative cases. In the remaining 56 negative TT patients, intestinal biopsy confirmed CD diagnosis and they were considered false negatives. Based on these results, specificity for the TT was 100% and sensitivity was 42.3%. On the basis of the present study, diagnosis of CD can be reliably performed without a duodenal biopsy in children with only extra-intestinal symptoms.

Full Text Available Glanzmann's thrombasthenia (GT is a rare autosomal recessive disorder in which the platelets have anomalies of fibrinogen receptors causing bleeding tendencies. The disease usually presents with mucosal bleeding, petechial haemorrhages or gastrointestinal (GI bleeding. Only sporadic cases of intussusception or duodenal haematoma have been reported with GT. We present a case of 5-year-old girl admitted with non-bilious vomiting, watery diarrhoea and abdominal pain. She is a known patient of Glanzmann's thrombasthenia.

Helicobacter pylori infection as a cause of gastritis, duodenal ulcer, gastric cancer and nonulcer dyspepsia: a systematic overview.

To evaluate current evidence for a causal relation between Helicobacter pylori infection and gastritis, duodenal ulcer, gastric cancer and nonulcer dyspepsia. A MEDLINE search for articles published in English between January 1983 and December 1992 with the use of MeSH terms Helicobacter pylori, gastritis, duodenal ulcer, gastric cancer, dyspepsia and clinical trial; abstracts were excluded. Six journals and Current Contents were searched manually for pertinent articles published in that time frame. Original studies with at least 25 patients, case reports and reviews that examined the relation between H. pylori and the four gastrointestinal disorders; 350 articles were on gastritis, 122 on duodenal ulcer, 44 on gastric cancer and 96 on nonulcer dyspepsia. The quality of the studies was rated independently on a four-point scale. The strength of the evidence was assessed using a six-point scale for each of the eight established guidelines for determining a causal relation. There was conclusive evidence of a causal relation between H. pylori infection and histologic gastritis. Koch's postulates for the identification of a microorganism as the causative agent of a disease were fulfilled for H. pylori as a causative agent of gastritis. There was strong evidence that H. pylori is the main cause of duodenal ulcers not induced by nonsteroidal anti-inflammatory drugs, but all of Koch's postulates were not fulfilled. There was moderate epidemiologic evidence of an association between chronic H. pylori infection and gastric cancer. There was a lack of convincing evidence of a causal association between H. pylori and nonulcer dyspepsia. The evidence supports a strong causal relation between H. pylori infection and gastritis and duodenal ulcer and a moderate relation between such infection and gastric cancer. Further studies are needed to clarify the role of H. pylori in these disorders. Thus far, there is no evidence of a causal relation between H. pylori and nonulcer

Effects of diphosphonate on kidney calcium content and duodenal absorption of 45calcium

Goulding, A.; Cameron, V.

1978-01-01

In rats the relationships between EHDP-induced changes in serum calcium concentration, kidney calcium content and duodenal transport of 45 calcium were studied. Body weights and kidney weights were similar in all groups. EHDP administration was associated with an increase in serum calcium concentration and kidney calcium content, and a decrease in duodenal 45 calcium transport. In the EHDP-treated rats, there was a significant negative correlation between kidney calcium concentration and duodenal 45 calcium transport but no correlation between either kidney calcium content and serum calcium concentration (r = 0.116) or between serum calcium concentration and duodenal 45 calcium transport (r = 0.02). Further experiments will be needed to determine whether the demonstrated increase in kidney calcium content induced by EHDP administration was the cause of, or was secondary to, inhibition of 1, 25(OH) 2 D 3 synthesis.

Full Text Available 2.6% of pancreatic cancer patients have the primary manifestation of gastrointestinal bleeding. It is not feasible to stop the duodenal hemorrhage caused by the pancreatic cancer infiltration. A 43-year-old woman who was diagnosed as having pancreatic cancer with multiple hepatic metastases and duodenal infiltration was administered gemcitabine and S-1 combination therapy. During the chemotherapy, initially, bleeding occurred due to duodenal infiltration. However, we continued the chemotherapy and duodenal infiltration was markedly reduced in size and did not rebleed. Aggressive chemotherapy contributed to maintenance of performance status as well as improvement of quality of life for the patient.

Combined pancreatic and duodenal transection injury: A case report.

Science.gov (United States)

Mungazi, Simbarashe Gift; Mbanje, Chenesa; Chihaka, Onesai; Madziva, Noah

2017-01-01

Combined pancreatic-duodenal injuries in blunt abdominal trauma are rare. These injuries are associated with high morbidity and mortality, and their emergent management is a challenge. We report a case of combined complete pancreatic (through the neck) and duodenal (first part) transections in a 24-year-old male secondary to blunt abdominal trauma following a motor vehicle crash. The duodenal stumps were closed separately and a gastrojejunostomy performed for intestinal continuity. The transacted head of pancreas main duct was suture ligated and parenchyma was over sewn and buttressed with omentum. The edge of the body and tail pancreatic segment was freshened and an end to side pancreatico-jejunostomy was fashioned. A drain was left in situ. Post operatively the patient developed a pancreatic fistula which resolved with conservative management. After ten months of follow up the patient was well and showed no signs and symptoms of pancreatic insufficiency. Lengthy, complex procedures in pancreatic injuries have been associated with poor outcomes. Distal pancreatectomy or Whipple's procedure for trauma are viable options for complete pancreatic transections. But when there is concern that the residual proximal pancreatic tissue is inadequate to provide endocrine or exocrine function, preservation of the pancreatic tissue distal to the injury becomes an option. Combined pancreatic and duodenal injuries are rare and often fatal. Early identification, resuscitation and surgical intervention is warranted. Because of the large number of possible combinations of injuries to the pancreas and duodenum, no one form of therapy is appropriate for all patients. Copyright © 2017 The Authors.

2015-01-01

Full Text Available Duodenal intramural hematoma (DIH usually occurs in childhood and young adults following blunt abdominal trauma. It may also develop in the presence of coagulation disorders and may rarely be an iatrogenic outcome of endoscopic procedures. Management of DIH is usually a conservative approach. A case of intramural duodenal hematoma that developed following endoscopic epinephrine sclerotherapy and/or argon plasma coagulation and that was nonresponsive to conservative therapy in a patient with chronic renal failure who died from sepsis is being discussed in this report. Clinicians should be aware of such possible complications after endoscopic hemostasis in patients with coagulation disorders.

Coeliac disease is increasingly recognized as a global problem in both children and adults. Traditionally, the findings of characteristic changes of villous atrophy and increased intraepithelial lymphocytosis identified in duodenal biopsy samples taken during upper gastrointestinal endoscopy have...... been required for diagnosis. Although biopsies remain advised as necessary for the diagnosis of coeliac disease in adults, European guidelines for children provide a biopsy-sparing diagnostic pathway. This approach has been enabled by the high specificity and sensitivity of serological testing. However......, these guidelines are not universally accepted. In this Perspective, we discuss the pros and cons of a biopsy-avoiding pathway for the diagnosis of coeliac disease, especially in this current era of the call for more biopsies, even from the duodenal bulb, in the diagnosis of coeliac disease. In addition, a contrast...

Results of surgical treatment of 61 patients with injuries of the duodenum are analyzed. The causes of injuries were stab-incised wounds in 24 patients, missile wound -- in 7, closed abdominal trauma -- in 26, trauma of the duodenum during endoscopic papillosphincterotomy -- in 4. All the patients underwent surgery. Complications were seen in 32 (52.5%) patients, 21 patients died, lethality was 34.4%. Within the first 24 hours since the trauma 7 patients died due to severe combined trauma, blood loss, 54 patients survived acute period of trauma, including 28 patients after open trauma, 26 -- after closed and 4 -- after trauma of the duodenum during endoscopic papillosphincterotomy. Diagnostic and surgical policies are discussed. Results of treatment depending on kind and time of surgery are regarded. It is demonstrated that purulent complications due to retroperitoneal phlegmona, traumatic pancreatitis, pneumonia are the causes of significant number of unfavorable outcomes. Therefore, it is important to adequately incise and drainage infected parts of retroperitoneal fat tissue with two-lumen drainages. Decompression through duodenal tube is the effective procedure for prophylaxis of suture insufficiency and traumatic pancreatitis. Suppression of pancreatic and duodenal secretion with octreotid improves significantly surgical treatment results.

Intramural Duodenal Haematoma after Endoscopic Biopsy: Case Report and Review of the Literature

Directory of Open Access Journals (Sweden)

Claudia Grasshof

2012-01-01

Full Text Available The development of intramural duodenal haematoma (IDH after small bowel biopsy is an unusual lesion and has only been reported in 18 children. Coagulopathy, thrombocytopenia and some special features of duodenal anatomy, e.g. relatively fixed position in the retroperitoneum and numerous submucosal blood vessels, have been suggested as a cause for IDH. The typical clinical presentation of IDH is severe abdominal pain and vomiting due to duodenal obstruction. In addition, it is often associated with pancreatitis and cholestasis. Diagnosis is confirmed using imaging techniques such as ultrasound, magnetic resonance imaging or computed tomography and upper intestinal series. Once diagnosis is confirmed and intestinal perforation excluded, conservative treatment with nasogastric tube and parenteral nutrition is sufficient. We present a case of massive IDH following endoscopic grasp forceps biopsy in a 5-year-old girl without bleeding disorder or other risk for IDH, which caused duodenal obstruction and mild pancreatitis and resolved within 2 weeks of conservative management. Since duodenal biopsies have become the common way to evaluate children or adults for suspected enteropathy, the occurrence of this complication is likely to increase. In conclusion, the review of the literature points out the risk for IDH especially in children with a history of bone marrow transplantation or leukaemia.

We demonstrate with this case how these rare cases can lead to chronic lung aspirations and require multidisciplinary involvement.

The effect of dietary calcium and vitamin D3 on the duodenal cadmium transport in the rat

International Nuclear Information System (INIS)

Moriuchi, Sachiko; Otawara, Yoko; Hosoya, Norimasa; Noda, Setsuko.

1978-01-01

The effect of dietary Ca and vitamin D 3 on the duodenal Cd transport was observed in the rat using everted gut sac technique in vitro, 1. Duodenal Cd transport was significantly increased in vitamin D deficient rat, however, it was not influenced by dietary Ca. The duodenal tissue binding and/or uptake of Cd from mucosal incubation medium was neither influenced by vitamin D 3 nor dietary Ca. 2. The transported Cd to serosal medium was very little compared to the Cd binding and/or uptake of duodenal tissue, suggesting two steps mechanism for intestinal Cd transport. The first step is the transfer from mucosal medium to duodenal mucosa and the second step is from duodenal mucosa to serosal medium. The second step was influenced by vitamin D. These results suggested that a significant increase in hepatic Cd accumulation of vitamin D deficient rat could be ascribed to the increase in the intestinal Cd absorption. (author)

2002-01-01

Between Nov. 1994-Jan. 2001 we performed laparoscopic suture with omentoplasty of perforated duodenal ulcer (PDU) in 51 patients out of 56 it was intended (this constituted the laparoscopic group--LG). The selection criteria were young patients, age < 40 years, no associated diseases, onset of the operation under 12 hours from the occurrence of the perforation, absence of clear ulcer history. In the same period, we performed an open suture based on the same criteria in 105 patients (open group--OP). The results showed a difference between needed analgesia (2.8 days for LG vs. 5.2 days for OG) and a hospital stay of 6.1 days in LG vs. 7.7 days in OG. The incidence of postoperative complications was 5.88% in the LG and 7.61% in the OG with 1.96% and respective 1.90% reoperation rate. In conclusion laparoscopic suture of PDU with associated postoperative modern therapy of ulcer disease could be the treatment of choice in young patients.

Is epidermal growth factor involved in development of duodenal polyps in familial polyposis coli?

DEFF Research Database (Denmark)

Poulsen, Steen Seier

1988-01-01

Duodenal adenomas are a frequent extracolonic manifestation in patients with familial polyposis coli (FPC). Epidermal growth factor (EGF), a polypeptide that stimulates cellular growth and differentiation, is localized in Paneth cells in the small intestine. In two patients with FPC, we found EGF...... immunoreactivity in duodenal adenomas. Numerous EGF immunoreactive Paneth cells were localized, not as usually, in the bottom of the crypts, but scattered along the crypts alone or in clusters. We do not know whether EGF is involved in the development of duodenal polyps in FPC patients, or whether the present...

An Unusual Cause of Duodenal Obstruction: Persimmon Phytobezoar.

Fan, Shengxian; Wang, Jing; Li, Yousheng

2016-12-01

Duodenal phytobezoar, an unusual cause of acute duodenal obstruction, is rarely seen. The most common cause of this type of bezoar is persimmon. It frequently arises from underlying gastrointestinal tract pathologies (gastric surgery, etc.). Here, we report the case of a 66-year-old man who had undergone distal gastrectomy with Billroth I reconstruction for gastric cancer and experienced severe epigastric discomfort, abdominal pain, and vomiting for a few days. The abdominal computed tomography scan showed a large-sized mass in the horizontal portion of the duodenum. On following endoscopic examination, a large phytobezoar was revealed in the duodenum. He was treated with endoscopic fragmentation combined with nasogastric Coca-Cola. The patient tolerated the procedure well and resumed a normal oral diet 3 days later.

Full Text Available Purpose: Celiac is an autoimmune disease caused by of gluten proteins which can be found in multi-grain food like wheat, barley and oat. The disease affects more than 1% of population and characterized by intestinal inflammation. In celiac disease, mucosal damage is a dynamic process. It is shown that it has autoimmune components. It is also T-Cell mediated and can be categorised as a chronic inflammatory disease. The purpose of this study is to make modified Marsh classification of the duodenal biopsies that came to our department in the 10 years. The study deals with reassessment of all events and uncovering the low graded events that were not diagnosed. Material and Methods: 467 biopsies (diagnosed between 2001 and 2011 at the Cukurova University, Faculty of Medicine, Department of Pathology were taken and analyzed by two pathologists. Each sample was reevaluated without taking the previous reports into consideration and scored by using modified Marsh classification. Results: According to Modified Marsh Classification total of 48 cases were diagnosed as Type 1. Total of 6 cases according to Modified Marsh Classification was diagnosed as Type 2. Total of 11 cases according to Modified Marsh Classification was diagnosed as Type 3a. Total of 5 cases, according to Modified Marsh Classification, was diagnosed as Type 3b. Total of 6 cases according to Modified Marsh Classification was diagnosed as Type 3c. Conclusion: As a result of this study, it has been found that Modified Marsh Classification is a very important standardization tool for detection of suspicious duodenal biopsies and for early case examinations.

We present and discuss the imaging findings in an infant with an intussusception secondary to a duplication cyst in whom sonography also showed inversion of the orientation of the mesenteric vessels and a distended stomach. A contrast medium study revealed a proximal duodenal obstruction with a beak appearance suggestive of midgut volvulus. At surgery, an ileocolic intussusception causing duodenal obstruction without concomitant malrotation or volvulus was found. The combination of duodenal obstruction and abnormal relationship of the mesenteric vessels as a result of ileocolic intussusception has not previously been reported in the literature. (orig.)

Triple-Tube-Ostomy: A Novel Technique for the Surgical Treatment of Iatrogenic Duodenal Perforation

Directory of Open Access Journals (Sweden)

Nobuaki Fujikuni

2011-12-01

Full Text Available Although duodenal perforation is currently an infrequent complication of medical procedures, its incidence in the future predictably will increase as endoscopic treatment of duodenal neoplasms becomes more frequently used. In some cases, duodenal perforation is difficult to treat even surgically. We report here a novel technique called ‘triple-tube-ostomy’ for the treatment of iatrogenic duodenal perforation. Since November 2009, there have been three cases of iatrogenic perforation of the duodenum, due to various causes, which we have treated with our novel technique. The main principles of the technique are biliary diversion, decompression of the duodenum, and early enteral nutrition. All patients who underwent the triple-tube-ostomy procedure had good postoperative courses, with few complications. The novel surgical technique we describe in this report is safe, reliable, easy to learn and perform, and led to a good postoperative course in all cases where we performed it.

Peritonitis secondary to traumatic duodenal laceration in the presence of a large pancreatic pseudocyst: a case report

Directory of Open Access Journals (Sweden)

Seenath Marlon M

2011-10-01

Full Text Available Abstract Introduction A pancreatic pseudocyst is a common sequela of severe acute pancreatitis. Commonly, it presents with abdominal pain and a mass in the epigastrium several weeks after the acute episode and can be managed conservatively, endoscopically or surgically. We report a patient with a pancreatic pseudocyst awaiting endoscopic therapy who developed a life-threatening complication following a rather innocuous trauma to the abdomen. Case presentation A 23-year-old Asian male student presented as an emergency with an acute abdomen a week after a minor trauma to his upper abdomen. The injury occurred when he was innocently punched in the abdomen by a friend. He experienced only moderate discomfort briefly at the time. His past medical history included coeliac disease and an admission four months previously with severe acute pancreatitis. He was hospitalized for 15 days; his pancreatitis was thought to be due to alcohol binge drinking on weekends. Ultrasound scanning showed no evidence of gallstone disease. Five days after the trauma, he became anorexic, lethargic and feverish and started vomiting bilious content. Seven days post-trauma, he presented to our emergency department with severe abdominal pain. An emergency laparotomy was performed where a transverse linear duodenal laceration was found at the junction of the first and second part of his duodenum, with generalized peritonitis. His stomach and duodenum were stretched over a large pancreatic pseudocyst posterior to his stomach. It was postulated that an incomplete duodenal injury (possibly a serosal tear occurred following the initial minor trauma, which was followed by local tissue necrosis at the injury site resulting in a delayed presentation of generalized peritonitis. Conclusion This is the first reported case of a traumatic duodenal laceration following minor blunt trauma in the presence of a large pancreatic pseudocyst. Minor blunt abdominal trauma in a normal healthy adult

To evaluate the efficacy and safety of empiric transcatheter arterial embolization (TAE) for patients with massive bleeding from duodenal ulcers. During January 2000 and December 2009, 59 patients with duodenal ulcer bleeding in whom TAE was attempted after endoscopic therapy failed were retrospectively analyzed. The patients were divided into empiric TAE (n = 36) and identifiable TAE (n = 23) groups according to angiographic findings with or without identification of the bleeding sites. The technical and clinical success rate, recurrent bleeding rate, procedure-related complications, and clinical outcomes were evaluated. The technical and clinical success rates of TAE were 100% and 83%. The recurrent bleeding rate, clinical success, duodenal stenosis, and 30-day mortality after TAE were not significantly different between the empiric and identifiable TAE groups. A high rate of technical and clinical success was obtained with empiric TAE comparable to identifiable TAE in patients with massive bleeding from duodenal ulcers. There were no severe complications. Empiric TAE is an effective and safe method when a bleeding site cannot determined by angiography. Copyright © 2011 SIR. Published by Elsevier Inc. All rights reserved.

Endoscopic biliary and duodenal stenting (DS; double stenting) is widely accepted as a palliation therapy for malignant bilioduodenal obstruction. The aim of the current study was to investigate the patency and adverse events of duodenal and biliary stents in patients with DS. Patients who underwent DS from April 2004 to March 2017 were analyzed retrospectively with regard to clinical outcomes and predictive factors of recurrent biliary and duodenal obstruction (recurrent biliary obstruction [RBO] and recurrent duodenal obstruction [RDO]). A total of 109 consecutive patients was enrolled. Technical success of DS was achieved in 108 patients (99.1%). Symptoms due to biliary and duodenal obstruction were improved in 89 patients (81.7%). RBO occurred in 25 patients (22.9%) and RDO in 13 (11.9%). The median times to RBO and RDO from DS were 87 and 76 days, respectively. Placement of a duodenal uncovered self-expandable metal stent (U-SEMS) was significantly associated with RBO in the multivariable analysis (P = 0.007). Time to RBO was significantly longer in the duodenal covered self-expandable metal stent group than in the U-SEMS group (P = 0.003). No predictive factors of RDO were detected, and duodenal stent type was not associated with the time to RDO (P = 0.724). Double stenting was safe and effective for malignant bilioduodenal obstruction. Duodenal U-SEMS is a risk factor for RBO. The covered self-expandable metal stent is the preferred type of duodenal SEMS in patients with DS (Clinical trial registration number: UMIN000027606). © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Metastatic disease to the stomach or duodenum is an infrequent diagnosis, and head and neck squamous cell carcinoma (HNSCC) is one of the least common primary malignancies that lead to gastric or duodenal metastases. We report the case of a 65-year-old man with human immunodeficiency virus infection and previously diagnosed HNSCC who presented with melena. The patient had a percutaneous endoscopic gastrostomy tube placed 3 months prior to his presentation. Laboratory testing was significant for normocytic anemia and a digital rectal examination was positive for melena. Esophagogastroduodenoscopy revealed numerous cratered nodules with contact bleeding in the stomach as well as the duodenum that appeared malignant. Biopsies of the gastric and duodenal nodules were positive for p40 and CK 5/6, consistent with metastatic squamous cell carcinoma.

Full Text Available Groove pancreatitis (GP is a very infrequent subtype of chronic pancreatitis affecting the pancreatic-duodenal junction. It usually manifests in middle-aged men with a history of chronic alcoholism, though it has also been described in women and in individuals who do not consume alcohol[1]. Even though the underlying etiology is unclear, chronic alcohol consumption is known to increase the viscosity of the pancreatic juice and exacerbate the inflammatory process[2]. We present a case of GP that posed diagnostic difficulties because it manifested as ascites and duodenal thickening, with pancreatic imaging findings initially normal.

Full Text Available Introduction: Duodenal duplication cysts are rare congenital foregut anomalies, accounting for 2%–12% of all gastrointestinal tract duplications. Surgical excision entails risk of injury to the pancreaticobiliary structures due to proximity or communication with the cyst. We present a case of duodenal duplication cyst in a 3 year-old boy who successfully underwent endoscopic decompression. Case report: AT is a young boy who first presented at 15 months of age with abdominal pain. There was one subsequent episode of pancreatitis. Ultrasonography showed the typical double wall sign of a duplication cyst and magnetic resonance cholangio-pancreatography showed a large 5 cm cyst postero-medial to the second part of the duodenum, communicating with the pancreaticobiliary system and causing dilatation of the proximal duodenum. He subsequently underwent successful endoscopic ultrasound guided decompression at 3 years of age under general anesthesia, and had an uneventful postoperative recovery. Conclusion: Endoscopic ultrasound guided assessment and treatment of gastrointestinal duplication cysts is increasingly reported in adults. To the best of our knowledge, only one case of endoscopic treatment of duodenal duplication cyst, in an older child, has been reported thus far in the paediatric literature. In this paper, we review the current literature and discuss the therapeutic options of this rare condition.

Full Text Available Celiac disease is gluten induced enteropathy and is a chronic inflammatory disorder of the small intestine characterized by malabsorption. It is a common immune mediated disorder which is triggered by consumption of wheat (gluten. It occurs in genetically predisposed individuals (carriers of HLA-DQ2 and DQ8 haplotypes. It is characterized by inflammation of the small-intestinal mucosa and myriad gastrointestinal and systemic manifestations. A duodenal biopsy with positive serology is the gold standard for the diagnosis of Celiac disease. As there are changing presentation for Celiac disease, communication of pathologist and gastroenterologists is essential for appropriate interpretation of duodenal biopsy.

Objective: To outline the various treatment options and outcomes in penetrating pancreatico-duodenal injuries with emphasis on the operative decision making strategies. Study Design: Descriptive study. Place and Duration of Study: Department of Surgery at Combined Military Hospital Peshawar, from 1st June 2008 to 30th May 2010. Patients and Methods: All combat casualties with penetrating pancreaticoduodenal injuries (PPDI) received in 'Emergency reception' of Combined Military Hospital, Peshawar were included. Data was taken from the patients medical charts and by personal evaluation and entered in a proforma. The variables used were age, sex, cause of the injury, haemo-dynamic status, conscious level, intensive care treatment duration, time to initial exploration, associated injury, grade of pancreatic injury according to Penetrating Abdominal Trauma Index (PATI) scoring system, grade of duodenal injury (according to PATI scoring system), total PATI score, operative repair, total hospital stay, morbidity, and mortality. Results: Twenty three patients having either or both of PPDI were included in the study out of 196 combat casualities. No case was excluded on basis of presence of associated injury. Mean age was 29.26 years (SD+-6.489) with only one (4.3%) case of female gender, the rest were male patients or soldiers. Nineteen (82.6%) cases had primary mechanism/cause of injury being splinters from Improvised Explosive Devices (IEDs) or bomb blasts; while 4 (17.4%) cases had Gunshot Wounds. Eighteen (78.3%) patients were haemo-dynamically stable on arrival while 5 (21.7%) patients were unstable. Mean duration of stay in hospital was 10.6 days, with a range of 1-19 days (cases with high PATI score and un-stable haemodynamic status died with-in 24 hrs). Most cases of pancreatico-duodenal injury were of mild severity i.e. grade-1 or 2 and we encountered no case of grade-5 PPDI. Most commonly occurring associated injury was to small gut. Overall mortality was 6 (26

Full Text Available CONTEXT AND OBJECTIVES: Significant controversy exists regarding the best surgical treatment for complex duodenal injuries. The aims of this study were to report on a series of eight cases of duodenal repairs using pyloric exclusion and to describe reported complications or improvements in clinical outcomes among patients with complex duodenal trauma. DESIGN AND SETTING: Cross-sectional study followed by a case series in a university hospital. METHODS: Data on eight patients with duodenal trauma who underwent pyloric exclusion over a 17.5 year period were collected and analyzed. RESULTS: The causes of the injuries included penetrating gunshot wounds (GSW in five patients and motor vehicle accidents (blunt trauma in three patients. The time elapsed until surgery was longer in the blunt trauma group, while in one patient, the gunshot injury was initially missed and thus the procedure was carried out 36 hours after the original injury. The injuries were grade III (50% or IV (50% and the morbidity rate was 87.5%. Four patients (50% died during the postoperative period from complications, including hypovolemic shock (one patient, sepsis (peritonitis following the missed injury and pancreatitis with an anastomotic fistula (two patients. CONCLUSIONS: Pyloric exclusion was associated with multiple complications and a high mortality rate. This surgical technique is indicated for rare cases of complex injury to the duodenum and the surgeon should be aware that treatment with a minimalistic approach, with only primary repair, may be ideal.

Benign duodenal neoplasm is a rare occurrence. Minimally invasive tumor resection and anastomosis formation with an OrVil catheter is a novel approach to treating this disease. In this article, we present a new technique for duodenojejunal anastomosis. This technique was applied in 4 patients with benign distal duodenal tumors who were treated with minimally invasive surgery with robotic assistance. In 4 patients, after the removal of distal duodenal masses with a robotic technique, an orifice in the duodenum was opened to allow for the passage of a guidewire. The guidewire was removed from the orifice by holding it with forceps during an upper endoscopy. An OrVil catheter was sutured to the guidewire outside to allow 2 catheters to proceed consecutively. After the removal of the anvil, an end-lateral duodenojejunostomy was performed with a circular stapler. The patients included 3 men and 1 woman (average age, 56). The durations of the operations were 215, 175, 180, and 185 minutes. No complications were observed in any of the patients during the postoperative period. The patients began oral intake on the fifth day of the postoperative period, and they were discharged on the sixth postoperative day. Histopathologic analyses indicated that the removed tumors were adenomas in 2 patients and gastrointestinal stromal tumors (GISTs) in 2 patients. Clear surgical margins were observed in all of the patients. The placement of an OrVil catheter for anastomosis in benign neoplasms with distal duodenum localization and the subsequent achievement of duodenojejunal anastomosis with a circular stapler constitute a novel treatment approach.

Full Text Available The role of iron transport proteins in the pathogenesis of anemia in patients with diabetes mellitus (T2DM is still unclear. We investigated the expression of duodenal transporter proteins in diabetic patients with and without iron deficiency anemia (IDA. Methods. Overall, 39 patients were included: 16 with T2DM and IDA (group A, 11 with T2DM without IDA (group B, and 12 controls (group C. Duodenal mucosal expression of divalent metal transporter 1 (DMT1, ferroportin 1 (FPN, hephaestin (HEPH, and transferrin receptor 1 (TfR was evaluated by Western blotting. Chronic disease activity markers were measured as well. Results. FPN expression was increased in group A compared to group B and controls: 1.17 (0.72–1.46, 0.76 (0.53–1.04, and 0.71 (0.64–0.86, respectively (p=0.011. TfR levels were over expressed in groups A and B compared to controls: 0.39 (0.26–0.61, 0.36 (0.24–0.43, and 0.18 (0.16–0.24, respectively, (p=0.004. The three groups did not differ significantly with regard to cellular HEPH and DMT1 expression. The normal CRP and serum ferritin levels, accompanied with normal FPN among diabetic patients without IDA, do not support the association of IDA with chronic inflammatory state. Conclusion. In patients with T2DM and IDA, duodenal iron transport protein expression might be dependent on body iron stores rather than by chronic inflammation or diabetes per se.

We have recently evaluated a short endoscopic secretin test for exocrine pancreatic function. Bicarbonate concentration in duodenal juice is an important parameter in this test. Measurement of bicarbonate by back titration as the gold standard method is time consuming, expensive and technically difficult, thus a simplified method is warranted. We aimed to evaluate an automated spectrophotometric method in samples spanning the effective range of bicarbonate concentrations in duodenal juice. We also evaluated if freezing of samples before analyses would affect its results. Patients routinely examined with short endoscopic secretin test suspected to have decreased pancreatic function of various reasons were included. Bicarbonate in duodenal juice was quantified by back titration and automatic spectrophotometry. Both fresh and thawed samples were analysed spectrophotometrically. 177 samples from 71 patients were analysed. Correlation coefficient of all measurements was r = 0.98 (p titration gold standard. This is a major simplification of direct pancreas function testing, and allows a wider distribution of bicarbonate testing in duodenal juice. Extreme values for Bicarbonate concentration achieved by the autoanalyser method have to be interpreted with caution. Copyright © 2016 IAP and EPC. Published by Elsevier India Pvt Ltd.

Qureshi, S.; Ghazanfar, S.; Quraishy, M.S.

2014-01-01

Objective: To determine the outcome of duodenal stenting in palliation of patients with malignant pyloric and duodenal obstruction. Methods: The non-randomised prospective descriptive study was conducted at the Endoscopy Suite, Surgical Unit-IV, Civil Hospital, Karachi, from December 2007 to November 2010. All patients presenting with inoperable ampullary, pancreatic or biliary cancers causing duodenal obstruction and patients with resectable malignancy but unfit for surgery were included. The procedure was carried out by a single expert endoscopist under local or general anaesthaesia as required. Boston Scientific stents of variable sizes were used. Follow-up was done at 1 week, 1 month and 6 months. Data analysis was done using SPSS 15. Results: Over the study period, 159 (60%) males and 6 (40%) females were included in the study. The male-to-female ratio was 2:3. The overall age ranged from 25-80 years with a mean of 52.67+-15.07 years. Primary diagnosis was pyloric carcinoma in 7(46.6%), carcinoma Gallbladder in 4(26.6%), Duodenal carcinoma in 3(20%) and carcinoma head of pancreas in 1(6.6%). Relief of symptoms were seen in 11 (73.3%), while complications were seen in 2 (13.3%). Stents were inserted with technical success in 14 (93%) patients. Clinical success was seen in 11 (73%), with a mean survival of 74.27+-40.7 days (range: 15-180 days). No statistical significance was found when comparing the survival time with age, gender and diagnosis. Conclusion: Use of self-expandable metallic stents for gastroduodenal malignancies appears to be a feasible, safe and effective method, especially in those patients with limited life expectancy.

Down syndrome is an autosomal chromosome disorder, characterized by intellectual disability and muscle hypotonia. Muscle hypotonia is observed from neonates to adulthood in Down syndrome patients, but muscle hypertonicity is extremely unusual in this syndrome. During a study period of nine years, we found three patients with severe spastic quadriplegia among 20 cases with Down syndrome and congenital duodenal stenosis/atresia (3/20). However, we could find no patient with spastic quadriplegia among 644 cases with Down syndrome without congenital duodenal stenosis/atresia during the same period (0/644, P quadriplegia among 17 patients with congenital duodenal stenosis/atresia without Down syndrome admitted during the same period to use as a control group (0/17, P quadriplegia in patients with Down syndrome. Long-term survival is improving, and the large majority of people with Down syndrome are expected to live well into adult life. Management and further study for the various problems, representing a low prevalence but serious and specific to patients with Down syndrome, are required to improve their quality of life. © 2012 The Authors.

In patients with duodenal ulcer, mucosal blood flow of pentagastrin-stimulated stomach was studied using sup(99m)Tc-methylaminophenazone clearance technique published previously by the authors. Comparative investigations were carried out in active and inactive phases of the disease and in operated patients before and after highly selective vagotomy. The relation between gastric mucosal blood flow and acid secretion proved to be different from that of the normacid controls: in duodenal ulcer patients the secretory capacity in relation to the blood supply proved to be increased. Both the mucosal blood flow and acid secretion values were elevated in the active stage as compared to the inactive phase, while the proportion between them remained unchanged. The relation of secretion to mucosal blood flow after highly selective vagotomy became similar to that of the normal controls. It is suggested that the sup(99m)Tc-methylaminophenazone clearance method is a suitable tool to evaluate the effectiveness of vagotomy. (author)

Objectives. Zollinger-Ellison Syndrome (ZES) results in hypersecretion of gastric acid (via gastrinoma) leading to peptic ulcers, diarrhea, and abdominal pain. We describe the novel discovery of hypertrophic, heterotopic gastric mucosa in the proximal duodenal bulb in patients with ZES, which we hypothesize results in an increased incidence of postbulbar ulcers in patients with ZES (a mechanism previously unreported). We determined the incidence of the novel finding of duodenal gastric oxyntic hypertrophic heterotopia (GOH) in patients with ZES. Methods. Seven patients with ZES were enrolled. The diagnosis of ZES was established by hypergastrinemia, gastric acid hypersecretion, and a positive secretin test or based on biopsy specimens (evaluated via tissue staining). Basal acid output (BAO) and baseline gastrin secretion were determined by established methods. Endoscopic examinations with methylene blue staining and biopsy of the gastric and duodenal mucosa were conducted in all patients every 3–6 months for an average of 5 years. Results. The duodenal mucosa demonstrated hypertrophic GOH in 5 out of 7 patients with ZES and an intact stomach and duodenum. Biopsies from the bowel mucosa demonstrated patchy replacement of surface epithelium by gastric-type epithelium with hypertrophic oxyntic glands in the lamina propria in 5 patients. Two of the patients had no evidence of GOH in the duodenal bulb. Patients with GOH had an average serum gastrin level of 1245 pg/mL and BAO of 2.92 mEq/hr versus 724 pg/mL and 0.8 mEq/hr in patients without GOH. Conclusions. This study demonstrated the presence of duodenal mucosa with GOH in 5 out of 7 patients with ZES and an intact stomach and duodenum. The presence of hypertrophic and heterotopic gastric mucosa is proposed to result from increased gastrin levels and may contribute to the increased incidence of postbulbar ulcers in these patients.

The utilization of esophagogastroduodenoscopy (EGD) and related procedures continues to rise. Due to this increase in utilization is an inevitable rise in serious complications such as hemorrhage and perforation. One understudied and dreaded complication of EGD causing significant morbidity and mortality is duodenal perforation. We present the case of a 63-year-old male who presented to our institution's emergency room with dyspepsia, melanic stools, tachycardia, and hypotension. Initial laboratory evaluation was significant for severe anemia, lactic acidosis, and acute kidney injury, while CT scan of the abdomen pelvis did not suggest retroperitoneal hematoma or bowel perforation. An emergent EGD was performed which showed multiple bleeding duodenal ulcers that were cauterized and injected with epinephrine. Post-procedure the patient developed worsening abdominal pain, distension, diaphoresis, and tachypnea, requiring emergent intubation. A CT scan of the abdomen and pelvis with oral contrast confirmed pneumoperitoneum and duodenal perforation. Due to the patient's hemodynamic instability and multiple comorbidities, he was treated non-operatively with strict bowel rest and intravenous antibiotics. The patient ultimately had a 19-day hospital course complicated by renal failure requiring hemodialysis and an ischemic limb necessitating above knee amputation. This case describes an unsuccessful attempt at nonoperative management of duodenal perforation following EGD. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Because a traditional rendezvous (RV) technique implies stretching of the papilla, possibly leading to post-ERCP pancreatitis, an alternative duodenal RV technique was evaluated. The aim was to assess the effectiveness, safety, and amount of time spent performing duodenal RV versus traditional RV cannulation in orthotopic liver transplantation patients with a T-tube. We retrospectively reviewed data from a prospective ERCP database held by our university hospital. Twenty patients with a T-tube who had undergone ERCP for biliary adverse events after orthotopic liver transplantation were included. The successful cannulation rate, the amount of time spent performing cannulation, the post-ERCP pancreatitis rate, and hyperamylasemia 24 hours after the procedure were recorded. Successful cannulation was achieved by the duodenal RV technique in 9 of 10 patients (90%), taking 146 seconds (interquartile range 63-341 seconds) with a short learning curve effect. An unsuccessful duodenal RV procedure occurred because of the angulation of the hydrophilic tip of the guidewire while crossing the papilla, thus preventing cannulation. Successful cannulation was achieved by the traditional RV technique in all cases (N = 11), including the failed duodenal RV technique, taking 374 seconds (interquartile range 320-410 seconds) (P < .05 vs duodenal RV). However, no post-ERCP pancreatitis occurred after using the duodenal RV technique compared with 2 episodes of mild pancreatitis after using the traditional RV technique. Twenty-four hours after the procedure, the median amylasemia level was 84 IU/L (interquartile range 49-105 IU/L) and 265 IU/L (interquartile range 73-2945 IU/L) for the duodenal versus traditional RV techniques, respectively (P = not significant). In patients with a T-tube after liver transplantation, the duodenal RV technique was not associated with post-ERCP pancreatitis, presumably because of the reduction of stress on the major papilla.

It is known that at least 90% of duodenal ulcers are caused by infection with the bacterium Helicobacter pylori. Eradicating this organism usually results in complete resolution of the disease (Rosengren, Br J Gen Pract 46(409):491-492, 1996). To study the different changes if any in stomach wall at sites other than the ulcer in chronic duodenal ulcer patients by upper Gastro-Intenstinal Endoscopy followed by histopathological examination of different parts of stomach. This study was a retrospective study conducted in the Department of General surgery, V.S.S. Medical College, Burla, Sambalpur, odisha during the period of June 2007 to May 2009. Subjects were patients with chronic duodenal ulcer who underwent endoscopic examination, gastric biopsy and rapid urease test. Chronic gastritis of antrum, followed by erythematous pangastritis was the prominent feature both in endoscopy and histopathological examination. The Inflammatory change affected the mucosa and submucosa of the stomach wall. The prevalence rate of Helicobacter pylori was 84%, the antrum being the most common affected part (84%) followed by gastric fundus (41%). Chronic superficial atrophic gastritis of antrum, followed by pangastritis is the most common pathological abnormality in stomach wall in CDU cases. Gastric antrum is the most common site for H. pylori colonization followed by fundus. Presence of H. pylori in stomach wall is associated with active on chronic gastritis.

The efficacy of low-dose lansoprazole has not been established for the prevention of recurrent gastric or duodenal ulcers in those receiving long-term low-dose aspirin (LDA) for cardiovascular and cerebrovascular protection. This study sought to examine the efficacy of low-dose lansoprazole (15 mg once daily) for the secondary prevention of LDA-associated gastric or duodenal ulcers. Patients were randomized to receive lansoprazole 15 mg daily (n = 226) or gefarnate 50 mg twice daily (n = 235) for 12 months or longer in a prospective, multicenter, double-blind, randomized active-controlled trial, followed by a 6-month follow-up study with open-label lansoprazole treatment. The study utilized 94 sites in Japan and 461 Japanese patients with a history of gastric or duodenal ulcers who required long-term LDA therapy for cardiovascular and cerebrovascular disease. The primary endpoint was the development of gastric or duodenal ulcers. The cumulative incidence of gastric or duodenal ulcers on days 91, 181, and 361 from the start of the study was calculated by the Kaplan-Meier method as 1.5, 2.1, and 3.7%, respectively, in the lansoprazole group versus 15.2, 24.0, and 31.7%, respectively, in the gefarnate group. The risk of ulcer development was significantly (log-rank test, P lansoprazole group than in the gefarnate group, with the hazard ratio being 0.099 (95% confidence interval [CI] 0.042-0.230). Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term LDA therapy.

Results Most of the patients presented with upper abdominal pain and the use of radiologic studies was crucial for diagnosis. The most common treatment was laparotomy with filter or strut removal plus duodenum repair. However, clinical conditions of patients must be considered and the endovascular technique with endograft deployment into inferior vena cava may be an alternative. Conclusion Duodenal perforation by an inferior vena cava filter is uncommon and in high-risk surgical patients endovascular repair must be considered.

Duodenal hematomas from blunt abdominal trauma are uncommon in children and treatment strategies vary. We reviewed our experience with this injury at a large-volume children's hospital. A retrospective case series was assembled from January 2003-July 2014. Data collected included demographics, clinical and radiographic characteristics, and hospital course. Patients with grade I injuries based on the American Association for the Surgery of Trauma Duodenum Injury Scale were compared with those with grade II injuries. Nineteen patients met inclusion criteria at a median age of 8.91 y (range, 1.7-17.2 y). Mechanisms of injury included direct abdominal blow or handle bar injury (n = 9), nonaccidental trauma (n = 5), falls (n = 3), and motor vehicle accident (n = 2). Ten patients had grade I hematomas and nine had grade II. Hematomas were most frequently seen in the second portion of the duodenum (n = 9). Five patients underwent a laparotomy for concerns for hollow viscus injury. No patients required operative drainage of the hematoma; however, one patient underwent percutaneous drainage. Twelve patients received parenteral nutrition (PN) for a median duration of 9 d (range, 5-14 d). Median duration of PN for grade I was 6.5 d (range, 5-8 d) versus 12 d for grade II (range, 9-14 d; P = 0.016). Complications included one readmission for concern of bowel obstruction requiring bowel rest. This study suggests that duodenal hematomas can be successfully managed nonoperatively. Grade II hematomas are associated with longer duration of PN therapy and consequently longer hospital stays. These data can assist in care management planning and parental counseling for patients with traumatic duodenal hematomas. Copyright © 2015 Elsevier Inc. All rights reserved.

To evaluate the feasibility and clinical effectiveness of using a polyurethane-covered expandable nitinol stent in the palliative treatment of malignant duodenal obstruction. Under fluoroscopic guidance, a polyurethane-covered expandable nitinol stent was placed in 12 consecutive patients with malignant duodenal obstructions. All presented with severe nausea and recurrent vomiting. The underlying causes of obstruction were duodenal carcinoma (n=4), pancreatic carcinoma (n=4), gall bladder carcinoma (n=2), distal CBD carcinoma (n=1), and uterine cervical carcinoma (n=1). The sites of obstruction were part I (n=1), part II (n=8), and III (n=3). Due to pre-existing jaundice, eight patients with part II obstructions underwent biliary decompression prior to stent placement. An introducer sheath with a 6-mm outer diameter and stents 16 mm in diameter were employed, and to place the stent, and after-loading technique was used. Stent placement was technically successful in ten patients, and no procedural complications occuured. In one of two patients in whom there was technical failure, and in whom the obstructions were located in part III, the stent was placed transgastrically. Stent migration occurred in one patient four days after the procedure, and treatment involved the palcement of a second, uncovered, nitinol stent. After stent placement, symptoms improved in all patients. During follow-up, obstructive symptoms due to stent stenosis (n=1), colonic obstruction (n=1), and multiple small bowel obstruction (n=1) recurred in three patients. Two of these were treated by placing additional stents in the duodenum and colon, respectively. One of the eight patients in whom a stent was placed in the second portion of the duodenum developed jaundice. The patients died a mean 14 (median, 9) weeks after stent placement. The placement of a polyurethane-covered expandable nitinol stent seems to be technically feasible, safe and effective for the palliative treatment of malignant

Duodenal Obstruction by a Gallstone (Bouveret's Syndrome Managed by Endoscopic Stone Extraction: A Case Report and Review

1997-01-01

Full Text Available Gastric outlet obstruction caused by a large gallstone in the duodenum or pylorus (Bouveret's syndrome is a rare complication of gallstone disease. The presenting symptoms are often nonspecific and include nausea, vomiting, epigastric pain and a history of gallbladder disease. Although the diagnosis is established only at surgery in many cases, preoperative recognition by imaging techniques and endoscopy is desirable. Surgical treatment aims at removal of the ectopic gallstone, closure of the fistula and cholecystectomy. A case of Bouveret's syndrome is presented where endoscopic extraction of the duodenal gallstone was accomplished providing definitive treatment for this patient.

Duodenal acid exposure induces a duodenogastric reflex resulting in gastric relaxation, inhibition of antral motility, and sensitization of the proximal stomach to distension. Duodenal hypersensitivity to acid has been identified as a potential pathogenic mechanism in functional dyspepsia. The nature and localization of the duodenal acid-sensitive receptors are still elusive. We hypothesize that acid directly activates superficial afferent nerve endings in the duodenal mucosa, triggering the duodenogastric reflex. In a double-blind, randomized, crossover study in 13 healthy volunteers, benzocaine, a local anesthetic, vs saline was perfused in the duodenum 15 min before duodenal acid perfusion. Gastric responses were monitored by a barostat. Stepwise isobaric gastric distensions were performed before and during acid perfusion. Symptoms were evaluated by visual analogue scales for six dyspeptic symptoms and an overall perception score. Benzocaine perfusion caused a relaxation of the stomach prior to duodenal acidification, indicating the existence of an excitatory duodenogastric tone. Pretreatment of the duodenum with benzocaine reduced the acid-induced gastric relaxation by 50% and abolished the inhibition of phasic motility of the proximal stomach. Finally, sensitization to distension was more pronounced in the benzocaine condition because of higher proximal gastric volumes. These findings support a model in which different neuronal subpopulations are responsible for the motor and sensory limb of the acid-sensitive duodenogastric reflex, making benzocaine an unsuitable drug to treat duodenal hypersensitivity to acid. These data provide more insight in the contribution of duodenal neuronal input to gastric physiology in the fasting state. © 2013 Blackwell Publishing Ltd.

We report the incidence of peptic ulcers (duodenal, pyloric canal, gastric, and combined) verified by radiologic, endoscopic, or surgical evidence in a large Health Maintenance Organization (HMO) in Los Angeles, California. For members age 15 and above, the peptic ulcer incidence rate was 0.86 per 1,000 person-years (p-y) (males 1.10, females 0.63). The male to female sex ratio was 1.7. Two hundred twenty-two duodenal, 17 pyloric canal, 89 gastric, and 21 combined first-time diagnosed ulcer cases were located. For duodenal and pyloric canal ulcer, the incidence rate for members age 15 and above was 0.58 per 1,000 p-y (males 0.76, females 0.40). For gastric ulcer, the incidence rate for members age 15 and above was 0.21 per 1,000 p-y (males 0.23, females 0.18). The combined ulcer rate was 0.05 per 1,000 p-y (males 0.07, females 0.02). Gastric ulcer rates were two times higher in 1980 than in 1977. Peptic ulcer age-specific incidence rates increased with age. Incidence rates were much lower than those reported in previous studies, but the gastric to duodenal ulcer ratio and the age and sex relation to ulcer incidence were similar to those previously reported.

Full Text Available Background: Enteroendocrine cells are essential for the regulation of glucose metabolism, but it is unknown whether they are associated with clinical features of metabolic syndrome (MetS and fasting plasma metabolites. Objective: We aimed to identify fasting plasma metabolites that associate with duodenal L cell, K cell and delta cell densities in subjects with MetS with ranging levels of insulin resistance. Research design and methods: In this cross-sectional study, we evaluated L, K and delta cell density in duodenal biopsies from treatment-naïve males with MetS using machine-learning methodology. Results: We identified specific clinical biomarkers and plasma metabolites associated with L cell and delta cell density. L cell density was associated with increased plasma metabolite levels including symmetrical dimethylarginine, 3-aminoisobutyric acid, kynurenine and glycine. In turn, these L cell-linked fasting plasma metabolites correlated with clinical features of MetS. Conclusions: Our results indicate a link between duodenal L cells, plasma metabolites and clinical characteristics of MetS. We conclude that duodenal L cells associate with plasma metabolites that have been implicated in human glucose metabolism homeostasis. Disentangling the causal relation between L cells and these metabolites might help to improve the (small intestinal-driven pathophysiology behind insulin resistance in human obesity.

Alternative types of duodenal ulcer induced in mice by partial X irradiation of the thorax

The present study extends our earlier observations on gastrointestinal pathology in thorax-irradiated female CFLP mice. It shows that exposure of the lower mediastinum to single doses of 14-30 Gy X rays results in the formation of the proximal duodenal ulcer accompanied frequently by erosion of the antral gastric mucosa. X irradiation of the lateral thoracic fields is responsible for single ulcers in the proximity of duodenal papilla, often associated with a circumscribed area of degeneration of the fundic mucosa of the stomach. In view of the small amount of radiation received by the subdiaphragmatic parts of the alimentary tract, these gastro-duodenal lesions represent abscopal effects of thoracic irradiation

The Modified Kimura's Technique for the Treatment of Duodenal Atresia

Biagio Zuccarello

2009-01-01

Full Text Available Background/Purpose. Kimura's diamond-shaped-duodenoduodenostomy (DSD is a known technique for the correction of congenital intrinsic duodenal obstruction. We present a modification of the technique and review the advantages of this new technique. Methods. From 1992 to 2006, 14 newborns were treated for duodenal atresia. We inverted the direction of the duodenal incisions: a longitudinal incision was made in the proximal duodenum while the distal was opened by transverse incision. Results. Our “inverted-diamond-shaped-duodenoduodenostomy” (i-DSD allowed postoperative oral feeding to start on days 2 to 3, peripheral intravenous fluids discontinuity on days 3 to 8 (median values 3.6; time to achieve full oral feeds on days 8 to 12 (median values 9.4; the length of hospitalisation ranged from 10 and 14 days (median value 11.2. No complications related to the anastomosis, by Viz leakage, dehiscence, biliary stasis, or stenosis were observed. Conclusions. The i-DSD provides a safe procedure to protect the ampulla of Vater from injury and avoids any formation of a blind loop. The results show that patients who have i-DSD achieve full oral feeds in a very short time period and, consequently, the length of hospitalisation is also significantly reduced.

War, traffic and iatrogenic injuries of D3 duodenal segment

2005-01-01

Full Text Available Background. Injuries of the duodenum at the level of aortomesenteric clamp (segment D3 are with a high incidence of death due to the development of fistula and peritonitis. In three successfully managed cases, we applied the biliary surgery method. Case reports. All three cases were with the injuries of D3 duodenal segment. The first patient suffered from the blast perforation of duodenum at the level of the aortomesenteric clamp which occurred at the 7th day after the injury. The second patient suffered from the duodenal injury caused in a traffic accident. The third patient suffered from an iatrogenic injury at the beginning of D3 duodenal segment inflicted during ureterolithotomy. The described surgical procedure included basically the suture to narrow the site of the injury, then lateroterminal anastomosis with the Roux-en-Y jejunal flexure and, finally, the placement of a silicone prosthesis starting from the duodenum through the site of injury and the Roux-en-Y out. Octreotide and the total parenteral nutrition were administered to the patients postoperatively. Conclusion. The use of the releasing silicone prosthesis in all three patients provided the repair of the site of the injury with anastomosed Reux-en-Y jejunum.

To assess the feasibility and safety of a pancreas-preserving total duodenectomy in the management of severe duodenal injury caused by abdominal trauma. Two patients with both extensive injury of the duodenum and diffuse peritonitis underwent pancreas preserving total duodenectomy at our tertiary care centre. These two young male patients (age 20 and 22 years) presented 2 days and 6 hours respectively following blunt abdominal trauma. The duodenum was almost completely separated from the pancreas. Ampulla was seen as a button on the pancreas. Following total duodenectomy, reconstruction was performed by suturing the jejunum to the head of the pancreas anteriorly and posteriorly away from the ampulla (invagination of the pancreas into the jejunum). There were no complications attributable to the procedure. Both patients are well on follow up. A Pancreas-preserving total duodenectomy offers a safe alternative to the Whipple procedure in managing complex duodenal injury. This procedure avoids unnecessary resection of the adjacent pancreas and anastomosis to undilated hepatic and pancreatic ducts.

Aim: To describe the multidetector computed tomography (MDCT) features of primary, locally recurrent, and metastatic duodenal gastrointestinal stromal tumours (GISTs). Materials and methods: In this institutional review board-approved, Health Insurance Portability and Accountability Act of 1996 (HIPAA)-compliant, retrospective study, 25 patients [13 men, 12 women; mean age 56 years (34–74 years)] with histopathologically confirmed duodenal GISTs seen at Dana Farber Cancer Institute and Brigham and Women's Hospital from December 1999 to October 2009 were identified. The MDCT of primary tumours in six patients and follow-up imaging in all the 25 patients was reviewed by two radiologists in consensus. Electronic medical records were reviewed to document the clinical characteristics and management. Results: The mean size of the primary tumour was 3.7 cm (range 2.5–5.6 cm). Three of six primary tumours were in the second and third portions of the duodenum, one in the third portion, one in the third and fourth portions, and one in the fourth portion. Three of six of the tumours were exophytic, two were both exophytic and intraluminal, and one was intramural. The tumours were well-circumscribed, round or oval masses, with few lobulations, and were either homogeneously hyper-enhancing or heterogeneously isodense at MDCT. None of the tumours had necrosis, haemorrhage, calcification, or loco regional lymphadenopathy on imaging. Sixteen of 25 (64%) patients developed metastatic disease, the most common sites being liver (14/16; 87.5%) and peritoneum (5/16; 31%). Conclusion: Duodenal GISTs are well-circumscribed, round or oval masses, and occur in the second through fourth portions of the duodenum, without lymphadenopathy or duodenal obstruction. Duodenal GISTS metastasize frequently to the liver and peritoneum

The purpose of this paper is to describe our experience with endovascular obliteration of duodenal varices in patients with liver cirrhosis and portal hypertension. Balloon-occluded transvenous retrograde and percutaneous transhepatic anterograde embolizations were performed for duodenal varices in five patients with liver cirrhosis, portal hypertension, and decreased liver function. All patients had undergone previous endoscopic treatments that failed to stop bleeding and were poor surgical candidates. Temporary balloon occlusion catheters were used to achieve accumulation of an ethanolamine oleate-iopamidol mixture inside the varices. Elimination of the varices was successful in all patients. Retrograde transvenous obliteration via efferent veins to the inferior vena cava was enough to achieve adequate sclerosant accumulation in three patients. A combined anterograde-retrograde embolization was used in one patient with balloon occlusion of afferent and efferent veins. Transhepatic embolization through the afferent vein was performed in one patient under balloon occlusion of both efferent and afferent veins. There was complete variceal thrombosis and no bleeding was observed at follow-up. No major complications were recorded. Endovascular obliteration of duodenal varices is a feasible and safe alternative procedure for managing patients with portal hypertension and hemorrhage from this source. (orig.)

A SEVERE CASE OF ACUTE NECROTIC PANCREATITIS CAUSED BY DUODENAL CYST DUPLICATION

2018-03-01

Full Text Available Introduction. Duodenal duplication cyst (DDC is a rare congenital malformation that appears in the embryonic development of the digestive tract. It is a benign condition usually diagnosed in infancy and early childhood, being a rare and difficult diagnosis in adult population. DDC is a recognized cause of duodenal obstruction, acute pancreatitis, obstructive jaundice and even digestive hemorrhage. Case presentation. We report the case of a young adult male with abdominal pain history, who presents with recurrent episodes of acute severe necrotic pancreatitis. The abdominal computed tomography scan revealed a Balthazar C necrotic pancreatitis with partial thrombosis of the splenic vein and a cystic mass in the second part of the duodenum. The endoscopic ultrasonography (EUS established that the duodenal cystic lesion came from the second layer, meaning the submucosa. We performed endoscopic cystotomy with complete evacuation of the fluid content into the duodenum, with favorable clinical outcome. Conclusions. The particularity of the case is represented by the low incidence of this pathology and the rare form of presentation, meaning acute pancreatitis probably from pancreatic ductular hypertension caused by the DDC.

The endoscopic appearance of duodenitis is a common finding in patients undergoing endoscopy because of epigastric pain however, the relationship of the visual findings to histology is poorly defined. We set out to ascertain if there was a correlation between the endoscopic and histological appearances of the duodenal mucosa. Consecutive patients with epigastric pain referred for diagnostic gastroduodenoscopy were studied. The visual appearances of 'duodenitis' (erythema, erosions and sub-epithelial haemorrhage) were reported independently by two endoscopists. Duodenal biopsies were taken and assessed for: neutrophil infiltrate, mononuclear infiltrate, gastric metaplasia, villous atrophy and a breach in the mucosa. H pylori status was determined. Of the 93 patients with endoscopic features of duodenitis an increase in histological markers of inflammation was found in 75 (81%). However, histological inflammation was absent or minimal in 68 (73%). Conversely, biopsies from normal-looking mucosa revealed histological evidence of inflammation in 26 (27%). For patients with the endoscopic features of duodenitis the positive & negative predictive value for neutrophilic infiltrate was 39% and 98% respectively. Biopsies from erosions confirmed a breach in the mucosa in only 2 of 40 patients. Neutrophilic infiltrate occurred with NSAI ingestion and infection with H pylori. The endoscopic appearance of the duodenal mucosa is unreliable in determining the presence of histological inflammation. The endoscopic appearance of 'erosions' is not usually associated with a mucosal breach.

Oral administration of synthetic human urogastrone promotes healing of chronic duodenal ulcers in rats

The effect of oral administration of synthetic human epidermal growth factor/urogastrone (EGF/URO) on healing of chronic duodenal ulcers induced by cysteamine in rats was investigated and compared with that of cimetidine, a H2-receptor antagonist. After 25 and 50 days of treatment, synthetic human...... EGF/URO significantly increased healing of chronic duodenal ulcers to the same extent as cimetidine. Combined treatment with synthetic human EGF/URO and cimetidine for 25 days was more effective than synthetic human EGF/URO given alone, whereas combined treatment for 50 days was significantly more...... human EGF/URO is a potent inhibitor of gastric acid secretion when administered intravenously, but had no effect on acid secretion when given intraduodenally, which suggests that the effect of synthetic human EGF/URO is a direct action on the duodenal mucosa. In conclusion, this study showed that oral...

To determine the management of perforated duodenal ulcer at the University Hospital of the West Indies (UHWI) in this era of Helicobacter pylori, the medical records of all patients seen at the UHWI during the period July 1997 to June 2002 with an intra-operative diagnosis of perforated peptic ulcer were reviewed The records were analyzed for the following: age, gender, duration of symptoms, non-steroidal anti-inflammatory drug (NSAID) use, smoking status, operative repair duration of hospitalization, Helicobacter pylori status and medical therapy, peri-operative complications, mortality and recurrence. Ninety per cent of the cases were males. All females in whom perforation occurred were age 50 years and older compared to males where 58% of cases presented before age 50 years. Perforations in acute ulcers occurred in 80% of cases. The majority of patients were male smokers. Non-steroidal anti-inflammatory drug use was also an important risk factor in elderly females. Simple surgical closure and standard triple therapy antibiotics to eradicate Helicobacter pylori was the most common treatment offered. Mortality was one per cent and follow-up poor but 11% of patients had documented recurrent peptic ulceration. In this study population, perforated duodenal ulcer occured overwhelmingly in males less than 50 years of age. There is a trend towards exclusive simple surgical closure and H pylori eradication at the UHWI for patients with perforated duodenal ulcer but this needs to be supported by documentation of H pylori prevalence in the population of patients presenting with perforated peptic ulcers.

To evaluate if 3 mo oral supplementation with Eviendep® was able to reduce the number of duodenal polyps in familial adenomatous polyposis (FAP) patients with ileal pouch-anal anastomosis (IPAA). Eleven FAP patients with IPAA and duodenal polyps were enrolled. They underwent upper gastrointestinal (GI) endoscopy at the baseline and after 3 mo of treatment. Each patient received 5 mg Eviendep twice a day, at breakfast and dinner time, for 3 mo. Two endoscopists evaluated in a blinded manner the number and size of duodenal polyps. Upper GI endoscopies with biopsies were performed at the baseline (T0) with the assessment of the Spigelman score. Polyps > 10 mm were removed during endoscopy and at the end of the procedure a new Spigelman score was determined (T1). The procedure was repeated 3 mo after the baseline (T2). Four photograms were examined for each patient, at T1 and T2. The examined area was divided into 3 segments: duodenal bulb, second and third portion duodenum. Biopsy specimens were taken from all polyps > 10 mm and from all suspicious ones, defined by the presence of a central depression, irregular surface, or irregular vascular pattern. Histology was classified according to the updated Vienna criteria. At baseline the mean number of duodenal detected polyps was 27.7 and mean sizes were 15.8 mm; the mean Spigelman score was 7.1. After polypectomy the mean number of duodenal detected polyps was 25.7 and mean sizes were 7.6 mm; the mean Spigelman score was 6.4. After 3 mo of Eviendep bid, all patients showed a reduction of number and size of duodenal polyps. The mean number of duodenal polyps was 8 (P = 0.021) and mean size was 4.4 mm; the mean Spigelman score was 6.6. Interrater agreement was measured. Lesions > 1 cm found a very good degree of concordance (kappa 0.851) and a good concordance was as well encountered for smaller lesions (kappa 0.641). Our study demonstrated that short-term (90 d) supplementation with Eviendep® in FAP patients with IPAA

Duodenal Villous Atrophy in a TTG-Negative Patient Taking Olmesartan: A Case Report and Review of the Literature

Full Text Available Olmesartan, an angiotensin II receptor antagonist used to treat hypertension, is associated with few adverse effects. Here, a case of severe sprue-like enteropathy and acute kidney injury is described in a 68-year-old male taking olmesartan for 3-4 years. He presented to hospital with a five-week history of diarrhea, vomiting, and a 20 lb weight loss. Anti-TTG was negative with a normal IgA. Biopsies of the distal duodenum and duodenal cap revealed marked blunting of the villi with near complete villous atrophy of the biopsies from the bulb. There was an increase in intraepithelial lymphocytes as well as neutrophils in the surface epithelium. The patient’s diarrhea improved upon discontinuation of olmesartan and he returned to his previous weight. Repeat endoscopy four months later demonstrated complete resolution of inflammatory change with normal villous architecture. Long-term olmesartan use is associated with severe sprue-like enteropathy. The mechanism of intestinal injury is unknown. Duodenal biopsy results may mimic other enteropathies such as celiac disease. Physicians should consider medications as potential etiologies of enteropathy.

Surgery is the mainstay of treatment of patients with peptic duodenal perforation. With the advent of minimal access techniques, laparoscopy is being used for the treatment of this condition. Retrospective analysis of 120 consecutive patients (mean age 44.5 years; 111 men) with duodenal ulcer perforation who had undergone laparoscopic surgery. 87 patients had history of tobacco consumption, 12 were chronic NSAID users, 72 had Helicobacter pylori infection and 36 had a co-morbid condition. The mean time to surgery from onset of symptoms was 28.4 hours. The median operating time was 46 minutes. All patients underwent laparoscopic closure of the perforation with Graham's patch omentopexy; 12 patients underwent additional definitive ulcer surgery. The morbidity rate was 7.5%; no patient needed conversion to open surgery or died. The mean postoperative hospital stay was 5.8 days. Results of laparoscopic management of perforated peptic ulcer are encouraging, with no conversion to open surgery, low morbidity and no mortality.

To compare the clinical outcomes of uncovered and covered self-expandable metal stent placements in patients with malignant duodenal obstruction. A total of 67 patients were retrospectively enrolled from January 2003 to June 2013. All patients had symptomatic obstruction characterized by nausea, vomiting, reduced oral intake, and weight loss. The exclusion criteria included asymptomatic duodenal obstruction, perforation or peritonitis, concomitant small bowel obstruction, or duodenal obstruction caused by benign strictures. The technical and clinical success rate, complication rate, and stent patency were compared according to the placement of uncovered (n = 38) or covered (n = 29) stents. The technical and clinical success rates did not differ between the uncovered and covered stent groups (100% vs 96.6% and 89.5% vs 82.8%). There were no differences in the overall complication rates between the uncovered and covered stent groups (31.6% vs 41.4%). However, stent migration occurred more frequently with covered than uncovered stents [20.7% (6/29) vs 0% (0/38), P stent patency was longer in uncovered than in covered stents [251 d (95%CI: 149.8 d-352.2 d) vs 139 d (95%CI: 45.5 d-232.5 d), P stent (70 d) and covered stent groups (60 d). Uncovered stents may be preferable in malignant duodenal obstruction because of their greater resistance to stent migration and longer stent patency than covered stents.

Effect of dopamine-related drugs on duodenal ulcer induced by cysteamine or propionitrile: prevention and aggravation may not be mediated by gastrointestinal secretory changes in the rat

Dose- and time-response studies have been performed with dopamine agonists and antagonists using the cysteamine and propionitrile duodenal ulcer models in the rat. The experiments demonstrate that the chemically induced duodenal ulcer is prevented by bromocriptine, lergotrile and reduced by apomorphine or L-dopa. Aggravation of cysteamine-induced duodenal ulcer was seen especially after (-)-butaclamol, (-)-sulpiride, haloperidol and, less effectively, after other dopaminergic antagonists. The duodenal antiulcerogenic action of dopamine agonists was more prominent after chronic administration than after a single dose, whereas the opposite was found concerning the proulcerogenic effect of dopamine antagonists. In the chronic gastric fistula rat, both the antiulcerogens bromocriptine or lergotrile and the proulcerogens haloperidol, pimozide or (-)-N-(2-chlorethyl)-norapomorphine decreased the cysteamine- or propionitrile-induced gastric secretion. No correlation was apparent between the influence of these drugs on duodenal ulcer development and gastric and duodenal (pancreatic/biliary) secretions. In the chronic duodenal fistula rat, decreased acid content was measured in the proximal duodenum after haloperidol, and diminished duodenal pepsin exposure was recorded after bromocriptine. Furthermore, the aggravation by dopamine antagonists of experimental duodenal ulcer probably involves a peripheral component. The site of dopamine receptors and physiologic effects which modulate experimental duodenal ulcer remain to be identified, but their elucidation may prove to be an important element in the pathogenesis and treatment of duodenal ulcer

Coeliac disease is increasingly recognized as a global problem in both children and adults. Traditionally, the findings of characteristic changes of villous atrophy and increased intraepithelial lymphocytosis identified in duodenal biopsy samples taken during upper gastrointestinal endoscopy have been required for diagnosis. Although biopsies remain advised as necessary for the diagnosis of coeliac disease in adults, European guidelines for children provide a biopsy-sparing diagnostic pathway. This approach has been enabled by the high specificity and sensitivity of serological testing. However, these guidelines are not universally accepted. In this Perspective, we discuss the pros and cons of a biopsy-avoiding pathway for the diagnosis of coeliac disease, especially in this current era of the call for more biopsies, even from the duodenal bulb, in the diagnosis of coeliac disease. In addition, a contrast between paediatric and adult guidelines is presented.

Direct pancreatic function tests (PFTs) are often used to diagnose chronic pancreatitis (CP). We aimed to determine the temporal relationship between an abnormal PFT result, cross-sectional imaging, and clinical symptoms. All patients referred for endoscopic ultrasound (EUS) and PFT for suspected CP at our medical center from 2008 to 2010 were included. Each subject underwent EUS and PFT on the same day using secretin stimulation. Seventeen patients had duodenal HCO3 values of less than 80 mEq/L and were labeled as abnormal; the 25 other patients had at least 1 duodenal HCO3 values of 80 mEq/L or greater. Patients with abnormal PFTs had more parenchymal (2.0 vs 0.92, P = 0.012), ductal (1.18 vs 0.6, P = 0.036), and total features (3.18 vs 1.52, P = 0.009) than those with normal PFTs on EUS examination. There was no difference in regard to the frequency of abnormal CT scans (25% vs 15%, P = 0.139), diarrhea (67% vs 60%, P = 0.463), fat-soluble vitamin deficiency (33% vs 26%, P = 0.315), or diabetes (10% vs 4%, P = 0.066). Patients with equivocal imaging and abnormally low duodenal HCO3 have more EUS features of CP than do patients with normal duodenal HCO3 values, suggesting that low duodenal HCO3 values are among the first measurable abnormalities in CP.

Full Text Available Ectopic adrenocorticotropic hormone (ACTH syndrome is an uncommon disorder and comprises about 15% of all patients with Cushing's syndrome (CS. Duodenal carcinoids are rare, indolent tumors usually associated with a benign progression. We hereby report a rare case of CS resulting from ectopic ACTH secretion from a duodenal neuroendocrine tumor (NET presenting with liver metastasis. A 37-year-old female presented with abdominal discomfort and dyspepsia of 1-month duration. Ultrasound abdomen suggested a well-defined hypoechoic lesion in the left lobe of the liver, suggestive of neoplasia. On clinical examination, she had Cushingoid features and persistent hypokalemia. Midnight ACTH and cortisol levels were grossly elevated at 1027 pg/ml (n < 46 pg/ml and 87.56 μg/dl (n < 7.5 μg/ml, respectively. Both overnight and high-dose dexamethasone suppression test confirmed nonsuppressed cortisol levels - 86.04 and 84.42 μg/dl (n < 1.8 μg/ml, respectively. Magnetic resonance imaging brain showed a structurally normal pituitary gland. Computed tomography scan of the abdomen revealed hepatic lesion with bilateral adrenal enlargement. A diagnosis of ectopic ACTH-dependent CS was made. Intraoperatively, a duodenal lesion of 0.5 cm × 0.5 cm was identified alongside an 8 cm × 6 cm exophytic lesion in segment IV of the liver. Frozen section of the duodenal lesion was positive for NET. She underwent a Whipple's surgery, cholecystectomy, and left hepatic lobectomy. Postoperatively, she showed clinical and biochemical remission. Herewith, we report the third case of duodenal carcinoid tumor presenting as ectopic ACTH syndrome and the first with liver metastasis.

- Previous evidence trying to assess the risk of celiac disease among dyspeptic patients has been inconclusive, showing in some cases notorious discrepancies. - To determine the prevalence of celiac disease in patients with dyspepsia compared to healthy controls without dyspepsia. - Adult patients under evaluation for dyspepsia were invited to participate. These patients were offered an upper gastrointestinal endoscopy with duodenal biopsies. On the other hand, asymptomatic adult volunteers who performed a preventive visit to their primary care physician were invited to participate and agreed to undertake an upper gastrointestinal endoscopy with duodenal biopsies as well. Those patients with histologic signs of villous atrophy were furtherly evaluated and serological tests were performed in order to determine celiac disease diagnosis. Celiac disease prevalence was compared between groups. - Overall, 320 patients with dyspepsia and 320 healthy controls were recruited. There were no significant differences in terms of gender or age between groups. Celiac disease diagnosis was made in 1.25% (4/320) of patients in the dyspepsia group versus 0.62% (2/320) in the control group. - Patients with dyspepsia who underwent routine duodenal biopsies did not show an increased risk for celiac disease when compared to healthy individuals.

A 7 year old boy was admitted to hospital with gastroenteritis, which was complicated by an acute perforated duodenal ulcer. After oversewing of the perforation he made an uncomplicated recovery. Peptic ulceration is under-diagnosed in childhood and this leads to delay in diagnosis and appropriate management. Ulceration is associated with severe illness and viral infections, but perforation is rare.

Gastro-duodenal perforations: conventional plain film, US and CT findings in 166 consecutive patients

International Nuclear Information System (INIS)

Grassi, Roberto; Romano, Stefania; Pinto, Antonio; Romano, Luigia

2004-01-01

Introduction: Gastro-duodenal perforations may be suspected in patients with history of ulceration, who present with acute pain and abdominal wall rigidity, but radiological findings in these cases may be unable to confirm a clinical diagnosis. The aim of our study was to report our experience in the diagnosis of gastro-duodenal perforation by conventional radiography, US and CT examinations. Material and methods: We retrospectively reviewed medical records of 166 consecutive patients who presented in the last 2 years to our institutions with symptoms of acute abdomen and submitted to surgery at the Emergency Unit of the ''A.Cardarelli'' Hospital of Naples with a surgical finding of perforated gastro-duodenal ulcer. The evidence of free intraperitoneal air on abdominal plain film was considered as a direct or suggestive finding of perforation. Evidence of intraperitoneal free fluid and/or reduced intestinal peristalsis at sonographic examination were considered indirect signs of gastro-duodenal perforation. Evidence of free peritoneal gas at CT was considered as a direct evidence of gastro-duodenal perforation. Results: Twenty patients underwent immediate surgery with no preoperative imaging evaluation, in 10 of them the site of perforation was found in a juxta-pyloric region and in the others at level of duodenum. In 146 patients submitted to serial radiological investigations before surgery, the site of perforation was in 56 (38.3%) duodenal, in 52 (35.6%) juxta-pyloric, in 28 (19.1%) gastric and in 10 (6.8%) pyloric. The cause of perforation was in all cases gastric or duodenal ulceration, in seven cases involving pancreatic parenchyma. In 110 (75.4%) patients with direct findings of perforation, in 94 cases (85.5%) the correct diagnosis was established on abdominal plain film, in two (1.8%) with radiographic and sonographic examinations and in 14 (12.7%) on CT findings. In 36 (24,6%) patients with no direct findings of perforation, only 24 (16,4%) of them

Duodenal perforations during diagnostic upper endoscopy are rare; however, when therapeutic techniques are performed, the reported incidence is as great as 2.8%. Surgical repair is usually mandated, but it is associated with significant morbidity and mortality. To compare closure of duodenal perforations by using an over-the-scope clip (OTSC) with a surgical closure. Randomized, controlled animal study. Animal facility laboratory. Domestic pigs (24 females). Large (10-mm) duodenal perforations were created by using an endoscopic needle-knife. The animals were randomly assigned to either open surgical repair (n=12) or endoscopic closure by using the OTSC system (n=12). Pressurized leak tests were performed during necropsy. One major bleed occurred because of a liver injury during creation of the duodenotomy. Mean time for endoscopic closure was 5 minutes (range, 3-8 min; SD +/- 2). No complications occurred during any of the closure procedures. At necropsy, all OTSC and surgical closures demonstrated complete sealing of duodenotomy sites. Pressurized leak tests demonstrated a mean burst pressure of 166 mm Hg (range, 80-260; SD +/- 65) for OTSC closures and 143 mm Hg (range, 30-300, SD +/- 83) for surgical sutures. Ex vivo intact duodenal specimens exhibited a mean burst pressure of 247 mm Hg (range, 200-300; SD +/- 35), which was significantly higher compared with in vivo OTSC and surgical closures (P < .01). There were no significant differences between burst pressures of OTSC and surgical closures (P = .461). Nonsurvival setting. Endoscopic closure of duodenal perforations by using the OTSC system is comparable with surgical closure in a nonsurvival porcine model. This technique is easy to perform and seems suitable for repairing duodenal perforations. 2010 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc. All rights reserved.

Endoscopic Management of a Primary Duodenal Carcinoid Tumor

Full Text Available Carcinoids are rare, slow-growing tumors originating from a variety of different neuroendocrine cell types. They are identified histologically by their affinity for silver salts and by positive reactions to neuroendocrine markers such as neuron-specific enolase, synaptophysin and chromogranin. They can present with various clinical symptoms and are difficult to diagnose. We present the case of a 43-year-old woman who was referred for evaluation of anemia. Upper endoscopy showed a duodenal bulb mass around 1 cm in size. Histopathological and immunohistochemistry staining were consistent with the diagnosis of a carcinoid tumor. Further imaging and endoscopic studies showed no other synchronous carcinoid lesions. Endoscopic ultrasound (EUS revealed a 1 cm lesion confined to the mucosa and no local lymphadenopathy. Successful endoscopic mucosal resection of the mass was performed. Follow-up surveillance 6 months later with EUS and Octreoscan revealed no new lesions suggestive of recurrence. No consensus guidelines exist for the endoscopic management of duodenal carcinoid tumors. However, endoscopic resection is safe and preferred for tumors measuring 1 cm or less with no evidence of invasion of the muscularis layer.

Pancreatic trauma is an uncommon injury, occurring in only about 0.2% of blunt abdominal injuries, while duodenal injuries represent approximately 4% of all blunt abdominal injuries. When trauma of the pancreas and duodenum do not permit reparation, pancreatoduodenectomy (PD) is mandatory. In the reconstructive phase, the use of ductal ligation as an alternative to standard pancreaticojejunostomy has been reported by some authors. We report a case of polytrauma with pancreatic and duodenal injury in which the initial diagnosis failed to recognize the catastrophic duodenal and pancreatic situation. The patient was submitted for PD and the pancreatic stump was abandoned in the abdominal cavity after main pancreatic ductal ligation. This technique can minimize the morbidity and mortality of PD in patients with other organs or apparatus involved severely and extensively in trauma.

To evaluate the effects of detomidine on visceral and somatic nociception, heart and respiratory rates, sedation, and duodenal motility and to correlate these effects with serum detomidine concentrations. Nonrandomized, experimental trial. Five adult horses, each with a permanent gastric cannula weighing 534 +/- 46 kg. Visceral nociception was evaluated by colorectal (CRD) and duodenal distension (DD). The duodenal balloon was used to assess motility. Somatic nociception was assessed via thermal threshold (TT). Nose-to-ground (NTG) height was used as a measure of sedation. Serum was collected for pharmacokinetic analysis. Detomidine (10 or 20 microg kg(-1)) was administered intravenously. Data were analyzed by means of a three-factor anova with fixed factors of treatment and time and random factor of horse. When a significant time x treatment interaction was detected, differences were compared with a simple t-test or Bonferroni t-test. Significance was set at p Detomidine produced a significant, dose-dependent decrease in NTG height, heart rate, and skin temperature and a significant, nondose-dependent decrease in respiratory rate. Colorectal distension threshold was significantly increased with 10 microg kg(-1) for 15 minutes and for at least 165 minutes with 20 microg kg(-1). Duodenal distension threshold was significantly increased at 15 minutes for the 20 microg kg(-1) dose. A significant change in TT was not observed at either dose. A marked, immediate decrease in amplitude of duodenal contractions followed detomidine administration at both doses for 50 minutes. Detomidine caused a longer period of visceral anti-nociception as determined by CRD but a shorter period of anti-nociception as determined by DD than has been previously reported. The lack of somatic anti-nociception as determined by TT testing may be related to the marked decrease in skin temperature, likely caused by peripheral vasoconstriction and the low temperature cut-off of the testing device.

Full Text Available Abstract Introduction Cases of gallstone ileus account for 1% to 4% of all instances of mechanical bowel obstruction. The majority of obstructing gallstones are located in the terminal ileum. Less than 10% of impacted gallstones are located in the duodenum. A gastric outlet obstruction secondary to a gallstone ileus is known as Bouveret syndrome. Gallstones usually enter the bowel through a biliary enteral fistula. Little is known about the formation of such fistulae in the course of gallstone disease. Case presentation We report the case of a 72-year-old Caucasian woman born in Germany with a gastric outlet obstruction due to a gallstone ileus (Bouveret syndrome, with a large gallstone impacted in the third part of the duodenum. Diagnostic investigations of our patient included plain abdominal films, gastroscopy and abdominal computed tomography, which showed a biliary enteric fistula between the gallbladder and the duodenal bulb. Our patient was successfully treated by laparotomy, duodenotomy, extraction of the stone, cholecystectomy, and resection of the fistula in a one-stage surgical approach. Histopathological examination showed chronic and acute cholecystitis, with perforated ulceration of the duodenal wall and acute purulent inflammation of the surrounding fatty tissue. Four months prior to developing a gallstone ileus our patient had been hospitalized for cholecystitis, a large gallstone in the gallbladder, cholangitis and a small obstructing gallstone in the common biliary duct. She had been treated with endoscopic retrograde cholangiopancreatography, endoscopic biliary sphincterotomy, balloon extraction of the common biliary duct gallstone, and intravenous antibiotics. At the time of her first presentation, abdominal ultrasound and endoscopic examination (including esophagogastroduodenoscopy and endoscopic retrograde cholangiopancreatography had not shown any evidence of a biliary enteral fistula.

Mortality in perforated duodenal ulcer depends upon pre-operative risk: a retrospective 10-year study.

LENUS (Irish Health Repository)

Larkin, J O

2012-01-31

INTRODUCTION: Most patients presenting with acutely perforated duodenal ulcer undergo operation, but conservative treatment may be indicated when an ulcer has spontaneously sealed with minimal\\/localised peritoneal irritation or when the patient\\'s premorbid performance status is poor. We retrospectively reviewed our experience with operative and conservative management of perforated duodenal ulcers over a 10-year period and analysed outcome according to American Society of Anesthesiologists (ASA) score. METHODS: The records of all patients presenting with perforated duodenal ulcer to the Department of Surgery, Mayo General Hospital, between January 1998 and December 2007 were reviewed. Age, gender, co-morbidity, ASA-score, clinical presentation, mode of management, operative procedures, morbidity and mortality were considered. RESULTS: Of 76 patients included, 48 (44 operative, 4 conservative) were ASA I-III, with no mortality irrespective of treatment. Amongst 28 patients with ASA-score IV\\/V, mortality was 54.5% (6\\/11) following operative management and 52.9% (9\\/17) with conservative management. CONCLUSION: In patients with a perforated duodenal ulcer and ASA-score I-III, postoperative outcome is uniformly favourable. We recommend these patients have repair with peritoneal lavage performed, routinely followed postoperatively by empirical triple therapy. Given that mortality is equivalent between ASA IV\\/V patients whether managed operatively or conservatively, we suggest that both management options are equally justifiable.

Whipple's disease is a chronic multisystemic infection caused by Tropheryma whipplei that is characterized by arthritis, weight loss, and diarrhea. The immunological defects in the duodenal mucosa, the site of major replication of the agent underlying the pathogenesis of Whipple's disease, are poorly understood. Mucosal immunoglobulins are essential for the defense against intestinal pathogens; therefore, we analyzed the B-cell response in duodenal specimens and sera of Whipple's disease patients. Whereas systemic immunoglobulin production was affected only marginally, duodenal biopsy specimens of Whipple's disease patients contained reduced numbers of immunoglobulin-positive plasma cells and secreted less immunoglobulin compared to healthy controls but showed a weak secretory IgA response toward T. whipplei. This T. whipplei-specific intestinal immune response was not observed in controls. Thus, we were able to demonstrate that general mucosal immunoglobulin production in Whipple's disease patients is impaired. However, this deficiency does not completely abolish T. whipplei-specific secretory IgA production that nonetheless does not protect from chronic infection. PMID:20696822

2011-01-01

Objective: To evaluate the efficacy and feasibility of emergency transcatheter arterial embolization (ETAE) in treating critical massive bleeding due to duodenal bulb ulcer. Methods: ETAE was carried out in seven patients with acute massive bleeding due to endoscopically-proved duodenal bulb ulcer, who failed to respond conservative measures and were critically ill clinically. Super-selective catheterization of gastroduodenal artery or right gastroepiploic artery was performed, which was followed by arterial angiography to identify the bleeding site. According to the angiographic findings, ETAE with Gelfoam particles and coils was carried out. After the operation medical management was given and endoscopy re-examination was conducted. All the patients were follow up for 3∼6 months. Results: Angiographically, gastroduodenal artery bleeding was detected in all seven patients. ETAE was successfully accomplished in all cases. Complete clinical effectiveness was obtained in six patients while partial effectiveness in one case. No procedure-related complications occurred. Conclusion: For critical massive bleeding due to duodenal bulb ulcer ETAE is a highly effective and safe treatment, which can be regarded as an alternative to surgery. It is worth popularizing this technique in clinical practice. (authors)

Lebwohl, B; Green, P H R; Genta, R M

Lymphocytic gastritis (LG) is an uncommon entity with varying symptoms and endoscopic appearances. This condition, as well as two forms of H. pylori-negative gastritis [chronic active gastritis (CAG) and chronic inactive gastritis (CIG)], appears to be more common in patients with coeliac disease (CD) based on single-centred studies. To compare the prevalence of LG, CAG and CIG among those with normal duodenal histology (or nonspecific duodenitis) and those with CD, as defined by villous atrophy (Marsh 3). We analysed all concurrent gastric and duodenal biopsy specimens submitted to a national pathology laboratory during a 6-year period. We performed multiple logistic regression to identify independent predictors of each gastritis subtype. Among patients who underwent concurrent gastric and duodenal biopsy (n = 287,503), the mean age was 52 and the majority (67%) were female. Compared to patients with normal duodenal histology, LG was more common in partial villous atrophy (OR: 37.66; 95% CI: 30.16-47.03), and subtotal/total villous atrophy (OR: 78.57; 95% CI: 65.37-94.44). CD was also more common in CAG (OR for partial villous atrophy 1.93; 95% CI: 1.49-2.51, OR for subtotal/total villous atrophy 2.42; 95% CI: 1.90-3.09) and was similarly associated with CIG (OR for partial villous atrophy 2.04; 95% CI: 1.76-2.35, OR for subtotal/total villous atrophy 2.96; 95% CI: 2.60-3.38). Lymphocytic gastritis is strongly associated with coeliac disease, with increasing prevalence correlating with more advanced villous atrophy. Chronic active gastritis and chronic inactive gastritis are also significantly associated with coeliac disease. Future research should measure the natural history of these conditions after treatment with a gluten-free diet. © 2015 John Wiley & Sons Ltd.

Human pancreatico-duodenal injuries caused by camels are extremely rare. We report three patients who sustained camel-related pancreatico-duodenal injuries and review the literature on this topic. A 32-year camel caregiver was kicked by a camel which then stepped on his abdomen trying to kill him. The patient's abdomen was soft and lax. CT scan of the abdomen showed free retroperitoneal air. Laparotomy revealed a complete tear of the anterior wall of the second part of duodenum which was primarily repaired. A 40-year camel caregiver was directly kicked into his abdomen by a camel. He developed traumatic pancreatitis which was treated conservatively. A 31-year-old male fell down on his abdomen while riding a camel. Abdominal examination revealed tenderness and guarding. Abdominal CT Scan showed complete transection of the neck of the pancreas which was confirmed by laparotomy. The patient had distal pancreatectomy with preservation of the spleen. All patients were discharged home in good condition. These cases demonstrate the misleading presentation of the camel-related pancreatico-duodenal injuries and their unique mechanism of injury.

Full Text Available Endoscopic closure techniques have been introduced for the repair of duodenal wall perforations that occur during endoscopic retrograde cholangiopancreatography (ERCP. We report a case of successful repair of a large duodenal wall perforation by using double endoscopic band ligation (EBL and an endoclip. Lateral duodenal wall perforation occurred during ERCP in a 93-year-old woman with acute calculous cholangitis. We switched to a forward endoscope that had a transparent band apparatus. A 2.0-cm oval-shaped perforation was found at the lateral duodenal wall. We repaired the perforation by sequentially performing double EBL and endoclipping. The first EBL was performed at the proximal edge of the perforation orifice, and two-thirds of the perforation were repaired. The second EBL, which also included the contents covered under the first EBL, repaired the defect almost completely. Finally, to account for the possible presence of a residual perforation, an endoclip was applied at the distal end of the perforation. The detection and closure of the perforation were completed within 10 minutes. We suggest that double EBL is an effective method for closure.

Chronic gastric and duodenal ulcers may result from ischemia determined by celiac trunk compression stenosis (CTCS). In such cases angiography is necessary to specify diagnosis, to bring to light the causes of ulceration and to define therapeutic tactics. An analysis of angiograms of 75 patients with gastric and duodenal mucosa ulcers in CTCS and its characteristics have presented. The opening and proximal part of the celiac trunk are more frequently subjected to compression. The length of a narrow part of the celiac trunk is on an average of 6.62±0.31 mm. Enlargement in the diameter of the gastroduodenal artery was noted. Simultaneous narrowing of the celaic trunk and the upper mesenteric artery was found in 18 patients

Full Text Available ABSTRACT BACKGROUND Previous evidence trying to assess the risk of celiac disease among dyspeptic patients has been inconclusive, showing in some cases notorious discrepancies. OBJECTIVE To determine the prevalence of celiac disease in patients with dyspepsia compared to healthy controls without dyspepsia. METHODS Adult patients under evaluation for dyspepsia were invited to participate. These patients were offered an upper gastrointestinal endoscopy with duodenal biopsies. On the other hand, asymptomatic adult volunteers who performed a preventive visit to their primary care physician were invited to participate and agreed to undertake an upper gastrointestinal endoscopy with duodenal biopsies as well. Those patients with histologic signs of villous atrophy were furtherly evaluated and serological tests were performed in order to determine celiac disease diagnosis. Celiac disease prevalence was compared between groups. RESULTS Overall, 320 patients with dyspepsia and 320 healthy controls were recruited. There were no significant differences in terms of gender or age between groups. Celiac disease diagnosis was made in 1.25% (4/320 of patients in the dyspepsia group versus 0.62% (2/320 in the control group. CONCLUSION Patients with dyspepsia who underwent routine duodenal biopsies did not show an increased risk for celiac disease when compared to healthy individuals.

Duodenal ulcers as an abscopal effect of thoracic irradiation in mice

International Nuclear Information System (INIS)

Michalowski, A.; Burgin, J.

1982-01-01

Female CFLP mice irradiated to their thorax with either x-rays or fast neutrons developed peptic ulcers within 8 days of exposure. The steep x-ray dose/response curve for induction of duodenal ulcer gave an ED 50 of approximately 14.5 Gu. As little as 6 Gy of fast neutrons was effective in some cases, but the neutron ED 50 exceeded that for x-rays. The ulcers represented an abscopal effect of thoracic irradiation. Scattered radiation as simulated by whole-body x-ray treatment (1 to 5 Gy) caused a dose-dependent decrease in the frequency of duodenal lesions, possibly by decreasing gastric secretion. The greater amount of scattered radiation accompanying fast neutron exposure of the thorax was presumably responsible for the shallower dose/response curve of ulcer induction than that seen with x-rays

Full Text Available A nine-year-old female Rottweiler with a history of repeated gastrointestinal ulcerations and three previous surgical interventions related to gastrointestinal ulceration presented with symptoms of anorexia and intermittent vomiting. Benign gastric outflow obstruction was diagnosed in the proximal duodenal area. The initial surgical plan was to perform a pylorectomy with gastroduodenostomy (Billroth I procedure, but owing to substantial scar tissue and adhesions in the area a palliative gastrojejunostomy was performed. This procedure provided a bypass for the gastric contents into the proximal jejunum via the new stoma, yet still allowed bile and pancreatic secretions to flow normally via the patent duodenum. The gastrojejunostomy technique was successful in the surgical management of this case, which involved proximal duodenal stricture in the absence of neoplasia. Regular telephonic followup over the next 12 months confirmed that the patient was doing well.

Full Text Available We investigated the effects of feeding diets with different starch sources on fermentation in the rumen, duodenal nutrient flow and nutrient digestibility. The basis of the diets was maize silage and alfalfa hay supplemented with wheat meal in diet W, or maize meal in diet M. The experiment was performed on four Black-Spotted bulls with mean live weight of 525 kg, which were fed twice daily at 06.30 and 18.30 h. Experimental animals were fitted with ruminal fistulae and duodenal T-shaped cannulae. Cr2O3 was used as a marker of nutrient flow to the duodenum. Rations were formulated so that the ratio of starch to crude fibre (CF was 2.1:1 and the percentage of CF was maintained at 17% (DM. Duodenal chymus was collected at 2-h time intervals. Starch origin significantly affected ruminal fermentation. Concentration of propionic, butyric and lactic acid was higher with wheat than with maize meal. When the maize meal was the source of starch there was a significantly higher flow of fat, CF, nitrogen-free extract, and starch into duodenum. Differences in duodenal flow of crude protein were not significant across the starch sources. Intake of wheat meal or maize meal increased duodenal flow relative to intake by 33% or 42 % respectively. The apparent digestibility of dry matter (76 ± 2%, crude protein (67 ± 0.9%, CF (64 ± 1.9%, nitrogen-free extract (82 ± 1.5% and organic matter (76 ± 1.3% was significantly higher by offering wheat meal.

The common presentation of coeliac disease has shifted from the historically classical symptoms of malabsorption in childhood to non-classical symptoms in adulthood such as irritable bowel syndrome-type symptoms, anaemia, chronic fatigue, change in bowel habit, abdominal pain and osteoporosis. A combination of coeliac serology and duodenal biopsy is required to diagnose coeliac disease in adults. Testing for IgA-tissue transglutaminase antibodies should be carried out as a first-line screening test. Advise patients to eat a gluten-containing diet for six weeks before their investigations to ensure the serological and histological results are not affected. A confirmatory duodenal biopsy is mandatory to ensure that patients are correctly diagnosed with coeliac disease. A lifelong strict gluten-free diet is the only effective treatment currently available. All patients should be referred to a specialist dietitian for guidance and support. Annual follow-up can begin when the disease is stable and patients are managing well on their diet.

Ursodeoxycholic acid counteracts celecoxib in reduction of duodenal polyps in patients with familial adenomatous polyposis: a multicentre, randomized controlled trial

Science.gov (United States)

2013-01-01

Background Due to prophylactic colectomy, mortality in patients with familial adenomatous polyposis (FAP) has changed, with duodenal cancer currently being the main cause of death. Although celecoxib reduces duodenal polyp density in patients with FAP, its long-term use may increase the risk of cardiovascular events and alternatives need to be explored. Preclinical studies suggest that the combination of celecoxib with ursodeoxycholic acid (UDCA) is a potentially effective strategy. We performed a randomized, double-blind, placebo-controlled trial to investigate the effect of celecoxib and UDCA co-treatment on duodenal adenomatosis in patients with FAP. Methods Patients with FAP received celecoxib (400 mg twice daily) and UDCA (1000-2000 mg daily, ~20-30 mg/kg/day, n=19) or celecoxib and placebo (n=18) orally for 6 months. Primary outcome was drug efficacy, assessed by comparing duodenal polyp density at pre- and post-intervention by blinded review of endoscopic recordings. As secondary outcomes, cell proliferation, apoptosis, and COX-2 levels in normal duodenal mucosa were assessed by immunohistochemistry or real-time quantitative polymerase chain reaction. Results In intention-to-treat analysis, deceased polyp density was observed after celecoxib/placebo treatment (p=0.029), whereas increased polyp density was observed after celecoxib/UDCA treatment (p=0.014). The difference in change in duodenal polyp density was statistically significant between the groups (p=0.011). No changes in secondary outcomes were observed. Thirty patients (81%) reported one or more adverse events, 16 patients (84%, Common Toxicity Criteria for Adverse Events version 3.0 (CTCAE) grade 1–3) treated with celecoxib/UDCA and 14 patients (78%, CTCAE grade 1–2) treated with celecoxib/placebo. Nine patients (24%) discontinued intervention prematurely, 5 patients (26%) treated with celecoxib/UDCA and 4 patients (22%) treated with celecoxib/placebo. Conclusions Celecoxib reduces duodenal

Purpose: To assess the efficacy of self-expanding metallic stents in treating inoperable gastric and duodenal stenoses during follow-up and to evaluate the complications encountered.Methods: A total of 31 patients suffering from gastroduodenal obstruction (29 malignant, 2 benign) were treated with a self-expanding metallic stent (Wallstent). In 24 cases insertion was by the peroral route, in seven cases via gastrostomy.Results: All the strictures were successfully negotiated under fluoroscopic guidance without having to resort to endoscopy. A total of 27 patients (87%) were able to resume a regular diet, a soft diet, or a liquid diet orally. Complications included one case of stent malpositioning, one case of leakage of ascitic fluid through the gastrostomy orifice, one case of perforation and fistula to the biliary tree, and two cases of hematemesis. In two patients (6%) additional stents were implanted to improve patency. In all patients follow-up was maintained until death. Recurrence of symptoms immediately before death occurred in seven cases (23%). Mean survival time of patients was 13.3 weeks (SE ± 4.6).Conclusions: The deployment of gastroduodenal stents resulted in good palliation of inoperable gastric and duodenal stenoses. Certain technical aspects, e.g., adaptation of stents to bowel morphology, is critical to proper stent function and avoidance of complications

We report a case of recurrent transverse colon cancer invading the pancreas and duodenum that was successfully treated with biliary and duodenal stenting. A 46-year-old man underwent ascending colostomy for the treatment of obstructive transverse colon cancer with hepatic metastasis. Chemotherapy achieved a partial response, but the levels of tumor markers later began to rise again. He then underwent right hemicolectomy and partial hepatectomy. Post-operative chemotherapy was administered, but the recurrent tumor caused obstructive jaundice and duodenal obstruction. These were successfully treated with biliary and duodenal stenting, and the patient was able to remain at home and maintain his quality of life.

Motor-evacuatory stomach function by using continuous radiogastrography was studied in patients with duodenal ulcers. Radiogastrograms were analyzed before operation, on the 7th-15th day after selective proximal vagotomy performed either independently or in combination with draining operations. A faster evacuation of food from the stomach prevailed in an uncomplicated form of duodenal ulcer and compensated stenosis of the pyloroduodenal zone, evacuatory stomach function was retarded or absent in subcompensated and decompensated stenosis. Discoordinated gastric peristalsis and a reverse food input were noted in patients with subcompensated stenosis. At early time after operations temporary inhibition of evacuatory stomach function occurred in 94.2% of the patients; it could be corrected with conservative therapeutic measures.

The body concentration of iron is regulated by a fine equilibrium between absorption and losses of iron. Iron can be absorbed from diet as inorganic iron or as heme. Hemopexin is an acute phase protein that limits iron access to microorganisms. Moreover, it is the plasma protein with the highest binding affinity for heme and thus it mediates heme-iron recycling. Considering its involvement in iron homeostasis, it was postulated that hemopexin may play a role in the physiological absorption of inorganic iron. Hemopexin-null mice showed elevated iron deposits in enterocytes, associated with higher duodenal H-Ferritin levels and a significant increase in duodenal expression and activity of heme oxygenase. The expression of heme-iron and inorganic iron transporters was normal. The rate of iron absorption was assessed by measuring the amount of (57)Fe retained in tissues from hemopexin-null and wild-type animals after administration of an oral dose of (57)FeSO4 or of (57)Fe-labelled heme. Higher iron retention in the duodenum of hemopexin-null mice was observed as compared with normal mice. Conversely, iron transfer from enterocytes to liver and bone marrow was unaffected in hemopexin-null mice. The increased iron level in hemopexin-null duodenum can be accounted for by an increased iron uptake by enterocytes and storage in ferritins. These data indicate that the lack of hemopexin under physiological conditions leads to an enhanced duodenal iron uptake thus providing new insights to our understanding of body iron homeostasis.

Low-dose lansoprazole has not been intensively evaluated for its efficacy in the prevention of recurrent gastric or duodenal ulcers in patients receiving long-term non-steroidal anti-inflammatory drug (NSAID) therapy for pain relief in such diseases as rheumatoid arthritis, osteoarthritis, and low back pain. This multi-center, prospective, double-blind, randomized, active-controlled study involving 99 sites in Japan was designed to compare the efficacy of lansoprazole (15 mg daily) with gefarnate (50 mg twice daily). Patients with a history of gastric or duodenal ulcers who required long-term NSAID therapy were randomized to receive lansoprazole 15 mg daily (n = 185) or gefarnate 50 mg twice daily (n = 181) and followed up for 12 months or longer prospectively. The cumulative incidence of gastric or duodenal ulcer at days 91, 181, and 361 from the start of the study was calculated by the Kaplan-Meier method as 3.3, 5.9, and 12.7%, respectively, in the lansoprazole group versus 18.7, 28.5, and 36.9%, respectively, in the gefarnate group. The risk for ulcer development was significantly (log-rank test, P lansoprazole group than in the gefarnate group, with the hazard ratio being 0.2510 (95% CI 0.1400-0.4499). A long-term follow-up study showed an acceptable safety profile for low-dose lansoprazole therapy, with diarrhea as the most frequent adverse event. Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term NSAID therapy.

Gastro duodenal ulcer is a common disorder of the gastrointestinal tract. Several Indian medicinal plants have been traditionally and extensively used to prevent different diseases. In the present research studies, Bael fruit (Aegle marmelos (AM), family: Rutaceae) which are also called as Bilva in ancient Sanskrit was used as a herbal drug and its antioxidative role in aspirin- induced gastroduodenal ulceration in albino rat was evaluated using essential biochemical parameters. Mucosal thickness (MT), ulcer index (UI), different biochemical parameters, such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), catalase (CAT), superoxide dismutase (SOD), reduced glutathione (GSH), and lipid peroxidation (LPO) were measured in all the groups, to study the possible involvement of antioxidants with gastroduodenal protection. A significant decrease in MT, SOD and CAT activities and GSH level and a significant increase in UI, AST, ALT, and ALP activities and LPO level were observed in aspirin treated stomach and duodenum of albino rats. Pretreatment with AM fruit pulp extract for 14 consecutive days showed the reverse effects of aspirin suggesting gastro-duodenal protective and anti- ulcerogenic properties of AM through its antioxidant mechanism.

THE USE OF THE FORCEPS BIOPSY AS AN AUXILIARY TECHNIQUE FOR THE VISUALIZATION OF THE MAJOR DUODENAL PAPILLA USING THE FOWARD-VIEWING UPPER ENDOSCOPY

Directory of Open Access Journals (Sweden)

Nathalia Saber de ANDRADE

Full Text Available ABSTRACT BACKGROUND: - Conventional esophagogastroduodenoscopy is the best method for evaluation of the upper gastrointestinal tract, but it has limitations for the identification of the major duodenal papilla, even after the use of the straightening maneuver. Side-viewing duodenoscope is recommended for optimal examination of major duodenal papilla in patients at high risk for lesions in this region. OBJECTIVE: To evaluate the use of the biopsy forceps during conventional esophagogastroduodenoscopy as an additional tool to the straightening maneuver, in the evaluation of the major duodenal papilla. METHODS: A total of 671 patients were studied between 2013 and 2015, with active major duodenal papilla search in three endoscope steps: not straightened, straightened and use of the biopsy forceps after straightening. In all of them it was recorded whether: major duodenal papilla was fully visualized (position A, partially visualized (position B or not visualized (position C. If major duodenal papilla was not fully visualized, patients continued to the next step. RESULTS: A total of 341 were female (50.8% with mean age of 49 years. Of the 671 patients, 324 (48.3% major duodenal papilla was identified in position A, 112 (16.7% in position B and 235 (35% in position C. In the 347 patients who underwent the straightening maneuver, position A was found in 186 (53.6%, position B in 51 (14.7% and position C in 110 (31.7%. Of the 161 remaining patients and after biopsy forceps use, position A was seen in 94 (58.4%, position B in 14 (8.7% and position C in 53 (32.9%. The overall rate of complete visualization of major duodenal papilla was 90%. CONCLUSION: The use of the biopsy forceps significantly increased the total major duodenal papilla visualization rate by 14%, reaching 604/671 (90% of the patients (P<0.01 and it can be easily incorporated into the routine endoscopic examination of the upper gastrointestinal tract.

Whipple disease is a granulomatous infectious disease caused by Tropheryma whipplei. The bacteria accumulate within macrophages, preferentially in the intestinal mucosa. Disease manifestation seems to be linked to immunological abnormalities of macrophages. We describe a patient with cerebral Whipple disease who presented with changes in mental status, confusion, inverse sleep-wake cycle, bilateral ptosis and vertical gaze palsy. Endoscopic biopsy sampling revealed Whipple disease in the gastric antrum but not in the duodenum. Whole blood stimulation displayed reactivity to T. whipplei that was at the lower end of healthy controls while reactivity of duodenal lymphocytes was not diminished. We propose that in cases of neurological symptoms suspicious of Whipple disease with normal duodenal and jenunal findings, biopsy sampling should be extended to the gastric mucosa. The robust reactivity of duodenal lymphocytes may have prevented our patient from developing small bowel disease, whereas the impaired reactivity in peripheral blood lymphocytes might yet explain the bacterial spreading to the central nervous system leading to the rare case of predominant neurological symptoms without relevant systemic involvement.

Full Text Available 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.

Full Text Available Abstract Background This study investigated if the H. pylori dupA genotype and certain host single nucleotide polymorphisms (SNPs of matrix metalloproteinases (MMPs and their inhibitors (TIMPs, including MMP-3, MMP-7, MMP-9, TIMP-1 and TIMP-2, might correlate with ulcer risk of H. pylori-infected Taiwanese patients. Results Of the 549 H. pylori-infected patients enrolled, 470 patients (265 with gastritis, 118 with duodenal ulcer, and 87 with gastric ulcer received SNPs analysis of MMP-3-1612 6A > 5A, MMP-7-181 A > G, MMP-9exon 6 A > G, TIMP-1372 T > C and TIMP-2-418 G > C by PCR-RFLP. The 181 collected H. pylori isolates were detected for the dupA genotype by PCR. The rates of dupA-positive H. pylori infection were similar among patients with duodenal ulcer (22.8%, gastric ulcer (20.0%, and gastritis (25.5% (p > 0.05. Males had higher rates of duodenal ulcer and gastric ulcer than females (p H. pylori-infected patients, the MMP-3 6A6A genotype were more common in patients with duodenal ulcers than in those with gastritis (87.7% vs. 74.9%, p p H. pylori-infected females. Conclusions The MMP-3 promoter polymorphism, but not the dupA-status, may correlate with susceptibility to duodenal ulcer after H. pylori infection in Taiwanese females.

Maintenance therapy with sucralfate in duodenal ulcer: genuine prevention or accelerated healing of ulcer recurrence?

Science.gov (United States)

Bynum, T E; Koch, G G

1991-08-08

We sought to compare the efficacy of sucralfate to placebo for the prevention of duodenal ulcer recurrence and to determine that the efficacy of sucralfate was due to a true reduction in ulcer prevalence and not due to secondary effects such as analgesic activity or accelerated healing. This was a double-blind, randomized, placebo-controlled, parallel groups, multicenter clinical study with 254 patients. All patients had a past history of at least two duodenal ulcers with at least one ulcer diagnosed by endoscopic examination 3 months or less before the start of the study. Complete ulcer healing without erosions was required to enter the study. Sucralfate or placebo were dosed as a 1-g tablet twice a day for 4 months, or until ulcer recurrence. Endoscopic examinations once a month and when symptoms developed determined the presence or absence of duodenal ulcers. If a patient developed an ulcer between monthly scheduled visits, the patient was dosed with a 1-g sucralfate tablet twice a day until the next scheduled visit. Statistical analyses of the results determined the efficacy of sucralfate compared with placebo for preventing duodenal ulcer recurrence. Comparisons of therapeutic agents for preventing duodenal ulcers have usually been made by testing for statistical differences in the cumulative rates for all ulcers developed during a follow-up period, regardless of the time of detection. Statistical experts at the United States Food and Drug Administration (FDA) and on the FDA Advisory Panel expressed doubts about clinical study results based on this type of analysis. They suggested three possible mechanisms for reducing the number of observed ulcers: (a) analgesic effects, (b) accelerated healing, and (c) true ulcer prevention. Traditional ulcer analysis could miss recurring ulcers due to an analgesic effect or accelerated healing. Point-prevalence analysis could miss recurring ulcers due to accelerated healing between endoscopic examinations. Maximum ulcer

Sucralfate is a basic aluminium salt of sucrose octasulphate which has been used in the treatment of peptic ulcers already for several years. Sucralfate administrated orally, coats selectively areas of ulceration, both gastric and duodenal, providing protection against acids and other irritants. The protective layer probably consists of sucralfate-protein complexes in the ulcerated areas. (orig.)

It is well known that coeliac disease is associated with autoimmune endocrine diseases, such as autoimmune thyroid disease and insulin-dependent diabetes mellitus. Recently, coeliac disease has been shown in approximately 10% of patients with autoimmune Addison's disease. Addison's disease is the most common cause of primary adrenocortical insufficiency and it shares several clinical features with coeliac disease. Although hyperpigmentation and hypotension are the most specific signs, gastrointestinal symptoms are common and can be the first complaints of the patients. The aim of our study was to investigate the prevalence of coeliac disease in Italian patients with Addison's disease. Seventeen consecutive patients affected by Addison's disease (14 F, mean age 53.9 years, range 26-79 years) were enrolled in the study. Eleven of them were affected by Addison's disease associated with autoimmune thyroid disease and/or insulin-dependent diabetes mellitus; the other 6 patients were suffering from isolated Addison's disease. Diagnosis had been performed at the age of 40.5 years (range 23-55). Steroid treatment had already been started in 16 of the patients. Endomysial antibodies were tested in all of them and a duodenal biopsy was taken in those found to be positive for antiendomysial antibody (EMA). One out of 17 patients was found to be EMA positive. Duodenal biopsy confirmed the diagnosis of coeliac disease by showing subtotal villous atrophy. Although we studied only a small sample, our preliminary results confirmed that Addison's disease is associated with coeliac disease, being present in 5.9% of patients with Addison's disease. Since the symptoms can be similar and treatment of Addison's disease can mask coeliac disease, this association should always be actively investigated.

Villous duodenal adenoma with II and III grade dysplasia and carcinoma in situ treated with cephalic duodenopancreatectomy

Full Text Available Background. Villous duodenal adenomas are rare, tend to malignant alteration and recurrence if surgical procedures are not sufficiently radical. They are mostly localized in the second portion of the duodenum and close to a papilla and are prone to malignant alteration. Case report. In this paper we presented a 79-year-old female patient already operated on twice elsewhere due to obstructive jaundice caused by villous duodenal adenoma, using, firstly, cholecystectomy and T-tube drainage of the choledoclus, and, then, an unsuccessful attempt of radical surgery − duodenopancreatectomy. The patient was some time wearing a T-tube drainage, and, then, submitted to endoscopic papillotomy, endoscopic stenting, and, finally to the insertion of a self-expandable metallic stent which got clogged three months later causing chalangitis. Three years following the first surgery, the patient presented to our institution and submitted to cephalic duodenopancreatectomy. Histology confirmed villous duodenal adenomas with II and III grade dysplasia and carcinoma in situ. The lymph nodes were tumour-free. The postoperative recovery was somewhat prolonged due to cardiologic difficulties and a mild infection of the wound. Conclusion. Villous duodenal adenoma is curable if treated correctly and in a proper time. Radical treatment delay increases the risk for malignant alteration which was the case with our patient who was submitted to it three years after the histologic confirmation of the diagnosis.

Six duodenally and ileally cannulated steers were used in 3 sequential studies to measure 1) basal nutrient flows from a soybean hull-based diet, 2) small intestinal digestibility of raw cornstarch continuously infused into the duodenum, and 3) responses of small intestinal starch digestion to duodenal infusion of 200 or 400 g/d casein. Our objective was to evaluate responses in small intestinal starch digestion in cattle over time and to measure responses in small intestinal starch digestion to increasing amounts of MP. On average, cattle consumed 3.7 kg/d DM, 68 g/d dietary N, and 70 g/d dietary starch. Starch flow to the duodenum was small (38 g/d), and N flow was 91 g/d. Small intestinal digestibility of duodenal N was 57%, and small intestinal digestion of duodenal starch flow was extensive (92%). Small intestinal starch digestibility was 34% when 1.5 kg/d raw cornstarch was continuously infused into the duodenum. Subsequently, cattle were placed in 1 of 2 replicated Latin squares that were balanced for carryover effects to determine response to casein infusions and time required for adaptation. Duodenal infusion of casein linearly increased (P ≤ 0.05) small intestinal starch digestibility, and small intestinal starch digestion adapted to infusion of casein in 6 d. Ethanol-soluble starch and unpolymerized glucose flowing to the ileum increased linearly (P ≤ 0.05) with increasing infusion of casein. Plasma cholecystokinin was not affected by casein infusion, but circulating levels of glucose were increased by casein supplementation (P ≤ 0.05). Responses in small intestinal starch digestion in cattle adapted to casein within 6 d, and increases in duodenal supply of casein up to 400 g/d increased small intestinal starch digestion in cattle.

Gastric bicarbonate secretion and release of prostaglandin E2 are increased in duodenal ulcer patients, but not in Helicobacter pylori positive healthy subjects

2016-01-01

Full Text Available Objective: Neuroendocrine tumors are neoplasms derived from endocrine cells, most commonly occurring in the gastrointestinal tract. Duodenal neuroendocrine tumors are rare tumors averaging 1.2–1.5 cm, and most are asymptomatic. Common presentation is abdominal pain, upper gastrointestinal bleed, constipation, anemia, and jaundice. Methods: An adult, Black, male patient with newly diagnosed diabetes mellitus presented to the emergency department with elevated liver function test and fatigue. Results: Magnetic resonance cholangiopancreatography demonstrated a large obstructing mass (3.6 cm × 4.4 cm × 3 cm within the second and third portions of the duodenum at the ampulla. Esophagogastroduodenoscopy demonstrated an ulcerated duodenal mass that was biopsied. Immunohistochemical stains were positive for synaptophysin, chromogranin B, and CK7. Chromogranin A was in normal range. Post-Whipple procedure demonstrated a 5.5 cm × 4.1 cm × 2.9 cm duodenal mass with invasion of the subserosal tissue of the small intestine, a mitotic rate of 2 per high-power field, and antigen Ki-67 of 2%–5%. Conclusion: This case raises the question as to if the patient developed diabetes mellitus due to the tumor size and location or if the new onset of diabetes was coincidental. This case also demonstrates the importance of a proficient history and physical.

Duodenal duplication cysts are rare congenital abnormalities which are more commonly diagnosed in infancy and childhood. However, in rare cases, these lesions can remain asymptomatic until adulthood. The combination of duplication cyst and pancreas divisum is extremely rare and both conditions have been linked with acute recurrent pancreatitis. We present the case of a 37 years-old patient who presented with repeated episodes of acute pancreatitis. By means of magnetic resonance imaging and endoscopic ultrasonography we discovered a duplication cyst whose cavity received drainage from the dorsal pancreas. After opening the cyst cavity to the duodenal lumen with a needle knife the patient presented no further episodes in the clinical follow-up. Comparable literature findings and therapeutic options for these abnormalities are discussed with regard to the presented case. PMID:21160764

Helicobacter pylori infection is now accepted as the most common cause of chronic active gastritis and peptic ulcer disease. The etiologies of many infectious diseases have been attributed to specific or clonal strains of bacterial pathogens. Polymerase chain reaction (PCR) amplification of DNA between repetitive DNA sequences, REP elements (REP-PCR), has been utilized to generate DNA fingerprints to examine similarity among strains within a bacterial species. Genomic DNA from H. pylori isolates obtained from 70 individuals (39 duodenal ulcers and 31 simple gastritis) was PCR-amplified using consensus probes to repetitive DNA elements. The H. pylori DNA fingerprints were analyzed for similarity and correlated with disease presentation using the NTSYS-pc computer program. Each H. pylori strain had a distinct DNA fingerprint except for two pairs. Single-colony DNA fingerprints of H. pylori from the same patient were identical, suggesting that each patient harbors a single strain. Computer-assisted cluster analysis of the REP-PCR DNA fingerprints showed two large clusters of isolates, one associated with simple gastritis and the other with duodenal ulcer disease. Cluster analysis of REP-PCR DNA fingerprints of H. pylori strains suggests that duodenal ulcer isolates, as a group, are more similar to one another and different from gastritis isolates. These results suggest that disease-specific strains may exist.

Intraluminal duodenal diverticulum (IDD) is a rare congenital anomaly. IDD can become symptomatic in 20% to 25% of cases when complicated by intestinal obstruction, pancreatitis, or hemorrhage. We report the case of a 21-year-old female presenting with IDD mimicking duodenoduodenal intussusception. We describe the imaging features of IDD on the gadoxetic acid-enhanced magnetic resonance image as well as computed tomography.

The prevalence of coeliac disease among patients with autoimmune hypothyroidism has not been studied before in Jordan and other Arab countries. A cross-sectional record-based review was made of all adult autoimmune hypothyroidism patients who attended a referral centre in Jordan, during an 8-month period. Coeliac disease in these patients was diagnosed by the attending physician based on positive serological tests for anti-endomysial antibodies IgA and IgG followed by duodenal biopsy to confirm the diagnosis of coeliac disease. Of 914 patients recruited, 117 (12.8%) were seropositive for coeliac disease. Of 87 seropositive patients who underwent duodenal biopsy, 39 had positive histological findings of coeliac disease (44.8%). Extrapolating from these findings the overall rate of coeliac disease among autoimmune hypothyroidism patients was estimated to be 5.7%. In multivariate logistic regression coeliac disease was significantly associated with older age (> 40 years), presence of other autoimmune diseases, vitamin B12 deficiency and anaemia.

Celiac disease, one of the best-known autoimmune human leukocyte antigen-dependent disorders, has a relatively increased prevalence in first-degree relatives. To determine the prevalence of celiac disease in siblings of patients with confirmed celiac disease. Siblings of confirmed celiac disease patients in our center were identified and enrolled in this study. Their serum immunoglobulin A and tissue transglutaminase antibody-enzyme-linked immunosorbent assay (anti-tissue transglutaminase, immunoglobulin A, and immunoglobulin G) were measured and multiple endoscopic duodenal biopsy specimens were obtained with parental consensus. Celiac disease was confirmed by observation of characteristic histological changes. A total of 49 children (male, 29; female, 20; age, 2-16 years) with confirmed celiac disease in a pediatric gastroenterology ward were studied from 1999 to 2006. We found 30 siblings (female, 16) all shared in both parents. The only measurement available was for immunoglobulin A tissue transglutaminase antibody. A duodenal biopsy was performed in all 30 siblings. Clinical findings such as abdominal pain, fatigue, growth retardation and diarrhea were found in 53.3% of the completely studied siblings, and positive serology without histological changes was identified in four cases. Both serology and biopsy (confirmed new cases) were positive in 2 of the 30 siblings. High prevalence of celiac disease among siblings of patients with confirmed celiac disease necessitates serologic screening (and confirmatory biopsy if indicated) in families having celiac disease. It is advantageous to diagnose the disease as soon as possible because early diagnosis and diet intervention may prevent serious complications such as growth retardation, short stature, chronic diarrhea, and malignancy.

Intestinal permeability to chromium-51 ethylenediamine tetraacetic acid in children with chronic obstructive respiratory disease: relationship with clinical and duodenal biopsy findings

1988-01-01

Intestinal permeability (IP) to 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

Full Text Available Gastrointestinal tract complications after abdominal aortic aneurysm (AAA repair are well known. The reported frequency ranges from 6.6% to 21%. However, the incidence of duodenal obstruction following AAA has probably been underestimated. This report concerns a 78-year-old male who was admitted for elective repair of an infrarenal AAA. On the ninth postoperative day, the patient presented with large quantities of bile-stained vomitus despite passing flatus per rectum. Metoclopramide and ranitidine were given under the initial impression of paralytic ileus. However, the upper gastrointestinal obstruction persisted, and on day 12, computerized tomography (CT revealed marked distension of the gastric tube and duodenum, down to the level of the third portion, with abrupt change of caliber at the point of the superior mesenteric artery (SMA. SMA syndrome was diagnosed. After nasogastric tube aspiration, parenteral nutrition, and 11 days of conservative treatment, abdominal CT and upper gastrointestinal series showed no apparent duodenal obstruction. The patient was discharged on the 29th postoperative day; follow-up abdominal CT 4 months later was unremarkable.

Helicobacter pylori genotyping from positive clotests in patients with duodenal ulcer

2000-01-01

Full Text Available Even though the seroprevalence of H. pylori may be high in the normal population, a minority develops peptic ulcer. Colonization of the gastric mucosa by more pathogenic vacA strains of H. pylori seems to be associated with enhanced gastric inflammation and duodenal ulcer. H. pylori genotyping from positive CLOtests was developed to determine the vacA genotypes and cagA status in 40 duodenal ulcer patients and for routine use. The pathogenic s1b/ m1/ cagA genotype was the most frequently occurring strain (17/42.5%; only two (5% patients presented the s2/ m2 genotype, the less virulent strain. Multiple strains were also detected in 17 (42.5% patients. Multiple strains of H. pylori colonizing the human stomach have been underestimated, because genotyping has been performed from cultures of H. pylori. We concluded that genotyping of H. pylori from a positive CLOtest had the advantages of reducing the number of biopsies taken during endoscopy, eliminating the step of culturing H. pylori, and assuring the presence of H. pylori in the specimen being processed.

To determine the prevalence of celiac disease in children and adolescents with migraine, the authors investigated serum levels of tissue transglutaminase antibody immunoglobulin A and total immunoglobulin A from 81 children with migraine and in a healthy control group of 176 children. Study participants who were positive for tissue transglutaminase immunoglobulin A antibodies underwent a duodenal biopsy. Two patients in the migraine group (2.5%) and 1 in the control group (0.57%) tested positive for serum tissue transglutaminase immunoglobulin A antibodies (P > .05). Duodenal biopsy did not confirm celiac disease in both groups, and these patients were considered "potential celiac" cases. In the present study, children with migraine did not exhibit a higher prevalence rate of celiac disease compared with healthy controls. Therefore, the screening test for celiac disease is not a necessary part of the management of migraine in children. © The Author(s) 2016.

This study assessed the influence of tumor localization of small bowel adenocarcinoma on survival after surgical resection. Patients with resected small bowel adenocarcinoma, ACJJ stage I-III, were identified from the Surveillance, Epidemiology, and End Results database from 2004 to 2013. The impact of tumor localization on overall and cancer-specific survival was assessed using Cox proportional hazard regression models with and without risk-adjustment and propensity score methods. Adenocarcinoma was localized to the duodenum in 549 of 1025 patients (53.6%). There was no time trend for duodenal localization (P = 0.514). The 5-year cancer-specific survival rate was 48.2% (95%CI: 43.3-53.7%) for patients with duodenal carcinoma and 66.6% (95%CI: 61.6-72.1%) for patients with cancer located in the jejunum or ileum. Duodenal localization was associated with worse overall and cancer-specific survival in univariable (HR = 1.73; HR = 1.81, respectively; both P matrimonial status were positive, independent prognostic factors. Duodenal localization is an independent risk factor for poor survival after resection of adenocarcinoma. © 2017 Wiley Periodicals, Inc.

The endogenous DNA adducts O(6)-carboxymethyl-deoxyguanosine (O(6)-CM-dG) and 3-ethanesulfonic acid-deoxycytidine (3-ESA-dC) are produced from N-nitroso bile acid conjugates, such as N-nitrosoglycocholic acid (NO-GCA) and N-nitrosotaurocholic acid (NO-TCA), respectively. Formation of these DNA adducts in vivo was here analyzed by 32P-postlabeling in the glandular stomach of rats subjected to duodenal content reflux surgery. In this model, all duodenal contents, including bile acid conjugates, flow back from the jejunum into the gastric corpus. The levels of O(6)-CM-dG found at 4 and 8 weeks after surgery were 40.9 +/- 9.4 and 56.3 +/- 3.2 per 10(8) nucleotides, respectively, whereas the sham operation groups had values of 5.8 +/- 2.3 and 5.9 +/- 0.5 per 10(8) nucleotides. Moreover, adduct spots corresponding to 3-ESA-dC were detected in both duodenal reflux and sham operation groups and levels in the duodenal reflux groups were around four-fold elevated at 11.2 +/- 1.0 and 8.9 +/- 1.0 per 10(8) nucleotides after 4 and 8 weeks, respectively. When the duodenal reflux animals were treated with a nitrite trapping agent, thiazolidine- 4-carboxylic acid (thioproline, TPRO), the levels of O(6)-CM-dG and 3-ESA-dC were reduced to the same levels as in the sham operation animals. These observations suggest that NO-TCA and NO-GCA are formed by nitrosation of glycocholic acid and taurocholic acid, respectively, and these nitroso compounds produce DNA adducts in the glandular stomach of rats subjected to duodenal content reflux surgery.

The epidemiology of peptic ulcer is characterised by marked geographic and temporal variations. Gastric ulcer occurs about 5-10 times more often than duodenal ulcer in Japan. In most European countries and the USA, duodenal ulcer is about twice as frequent as gastric ulcer. The variation among different European countries does not show any clear-cut relationship to European geography. The reported differences in healing rate, relapse rate after discontinuation of treatment with histamine2 (H2)-blockers, and harmful effects of smoking are probably related to the varying fraction of bad healers recruited for controlled clinical trials in different countries. In male migrant workers who emigrated from Southern to Central Europe, duodenal ulcer occurs twice as frequent as in the native population. A similar phenomenon has been reported from South Africa. Peptic ulcer used to be a rare disease before the 19th century. In the beginning of the 19th century acute perforations of gastric ulcers were first reported in young girls. With progress of the 19th century peptic ulcer became more frequent also in men. By the end of the century the incidence of duodenal ulcer had surpassed that of gastric ulcer. Studies from the USA and England reported that the number of hospital admissions, surgical operations, and deaths due to duodenal or gastric ulcer had declined during the last 20 years. A cohort analysis demonstrates that the temporal changes of peptic ulcer in all European countries, in Japan, and in the USA occur in a fashion characteristic of those due to changes in birth-cohort risks. Generations born in the last 30 years of the 19th century manifested the highest risk of developing peptic ulcer and carried it throughout their lives. The birth-cohorts with a high risk for duodenal ulcer lagged 10-30 years behind those with a high risk for gastric ulcer. The cohort phenomenon starts at an age below 5 years for both gastric and duodenal ulcer. The cohort phenomenon implies

A 60-year-old woman with massive hemorrhage from duodenal varices was transferred to our hospital for the purpose of transcatheter intervention. Although digital subtraction arterial portography could not depict the entire pathway of collateral circulation, the efferent route of the duodenal varices was clearly demonstrated on subsequent CT during arterial portography. Balloon-occluded retrograde transvenous obliteration (B-RTO) of the varices was performed via the efferent vein and achieved complete thrombosis of the varices

Duodenal acid infusion induces gastric relaxation and sensitization to distension in healthy volunteers. The acid-sensitive mechanism is still unknown. We hypothesized that 5HT(3)-blockade can inhibit the acid-induced duodenogastric sensorimotor reflex in healthy volunteers. Fourteen healthy volunteers were included in a randomized, double-blind placebo-controlled cross-over trial. An infusion tube with attached pH-electrode was positioned in the duodenum and a barostat balloon was located in the gastric fundus. Proximal gastric volume and sensitivity to distension were assessed before and during duodenal acid infusion and after pretreatment with intravenous (i.v.) ondansetron (a 5HT(3)-receptor antagonist, 8 mg) or saline. An overall perception score (0-6) and an assessment of nine dyspeptic symptoms by visual analogue scales (VAS) were obtained. Results are given as mean ± SEM. Ondansetron had no effect on duodenal pH and on the acid-induced increase of proximal gastric volume (increase of 80 ± 20 vs 83 ± 15 mL after ondansetron and placebo; effect of acid acid infusion and gastric distension. 5HT(3)-receptors are involved in acid-induced duodenogastric sensitization, but not in the duodenogastric inhibitory motor reflex. © 2010 Blackwell Publishing Ltd.

Management of Duodenal Adenomas Involving the Ampulla of Vater – A Warning against Limited Resection

2008-03-01

Full Text Available Duodenal adenomas are uncommon, however, when present a proportion have dysplasia associated with the adenoma and therefore require treatment. The options range from less invasive endoscopic treatments to a pancreaticoduodenectomy. This case report describes two patients with adenomas involving the ampulla of Vater. One patient had familial adenomatous polyposis, the other was a renal transplant patient with a large adenoma. Both patients’ adenomas contained high-grade dysplasia. Both patients underwent a pancreaticoduodenectomy. Histology of both specimens demonstrated that the adenoma had migrated up the bile duct for at least 7 mm, and the pancreatic duct for 8 mm in one patient. Limited resection of ampullary adenomas may leave residual adenomatous tissue in the bile duct with the risk of recurrent adenomatous disease and malignant transformation.

Duodenal ulcer-promoting gene (dupA) was recently described as a new putative Helicobacter pylori virulence marker associated with an increased risk for duodenal ulcer and reduced risk for gastric carcinoma in Japan and Korea. Since differences regarding the association among H. pylori markers and H. pylori-associated diseases have been demonstrated around the world, we evaluated the presence of the gene in 482 strains from Brazilian children (34 with duodenal ulcer and 97 with gastritis) and adults (126 with duodenal ulcer, 144 with gastritis and 81 with gastric carcinoma) by PCR using the described primers and an additional set of primers based on Brazilian strain sequences. The results were confirmed by sequencing. The presence of cagA was investigated by PCR and also included in the analysis. dupA was present in 445 (92.32%) and absent in 29 (6.02%) strains. All samples from children with and without duodenal ulcer were dupA-positive (p=1.0). No association was observed among the strains from adults with gastritis (92.36%), duodenal ulcer (87.30%, p=0.30) and gastric carcinoma (87.65%, p=0.31). Conversely, cagA-positve status remained independently associated with duodenal ulcer (children: odds ratios (OR)=5.58, 95% confidence intervals (CI)=1.67-18.50; adults: OR=3.33, 95% CI=2.14-5.19) and gastric carcinoma (OR=6.58, 95% CI=3.51-12.30) in multivariate analyses. The presence of dupA was significantly higher in strains from children than in those from adults (p=0.01). In conclusion, dupA is highly frequent and not associated with H. pylori-associated diseases in both Brazilian adults and children, which points to regional differences in the distribution of the gene.

Duodenal ulcer (DU) patients may have accelerated gastric emptying (GE) suggesting that there is an increase in unbuffered gastric acid reaching the duodenum contributing to DU disease. Aluminum-containing antacids were shown to delay GE. The authors' aim was to investigate whether another aluminum-containing compound, Sucralfate, affects GE in normal and DU patients. Nine normal volunteers and 10 patients with documented DU disease were studied. For each test the subject ingested a meal composed of chicken liver Tc-99m-S-C mixed with beef stew and eaten with 4 oz. of water labelled with 100μCi of III-in-DTPA. On two separate days, subjects received 1 gram of Sucralfate (190 mg of aluminum per gram) or placebo in a randomized double-blind fashion one hour prior to the test meal. GE of liquids and solids in normal subjects was not significantly changed by Sucralfate. Sucralfate in the DU patients significantly slowed liquid emptying in the initial 40 min and solid food throughout the study compared to placebo (p<0.05). This paper summarizes that; GE of solids but not liquids is accelerated in DU patients compared to normal subjects; and sucralfate delays GE of both liquid and solid components of a meal in DU patients but has no effect on GE in normals. The authors conclude that a slowing of gastric emptying possibly mediated by aluminum ions, may be one mechanism by which Sucralfate enhances healing and decreases recurrence of DU

The duodenal ulcer promoting gene (dupA) and dupA cluster in Helicobacter pylori have been described as a risk factor for duodenal ulcer development in some populations. Polymorphic gene dupA can be divided into two groups, intact dupA1 (long or short type based on the presence or absence of 615-bp extra sequences at the 5' region) having complete reading frame and other truncated dupA2 having frame-shift mutation. This study was aimed to elucidate the role of dupA of H. pylori and their clusters in the disease manifestation of Indian population. A total of 170 H. pylori strains were screened for the presence of dupA, dupA alleles and dupA cluster by PCR and sequencing. Pro-inflammatory cytokine (IL-8) with different dupA variant H. pylori stimulated gastric epithelial cells (AGS cells) was measured by ELISA. A total of 50 strains (29.4%) were positive for dupA among the tested 170 strains. The prevalence of dupA1 in duodenal ulcer (DU) and non-ulcer dyspepsia (NUD) populations was found to be 25.5% (25/98) and 11.1% (8/72), respectively and 16.4% (28/170) of the tested strains had dupA1, cagA and vacAs1m1 positive. The distribution of long and short type dupA1 has not been significantly associated with the disease outcome. The dupA cluster analysis showed that 10.2% (10/98) and 8.3% (6/72) strains were positive among DU and NUD, respectively. IL-8 production was significantly higher in dupA1(+) , cagA (+), vacA (+) (902.5 ± 79.01 pg/mL) than dupA2 (+) , cagA (+) , vacA (+) (536.0 ± 100.4 pg/mL, P = 0.008) and dupA (-), cagA (+), vacA (+) (549.7 ± 104.1 pg/mL, P = 0.009). Phylogenetic analysis of dupA indicated that the Indian H. pylori strains clustered with East Asian strains but distinct from Western strains. This is the first known genetic element of Indian H. pylori that is genetically closer to the East Asian strains but differed from the Western strains. The intact dupA1 was significantly associated with DU than NUD (P = 0

Full Text Available CONTEXT: Celiac disease, one of the best-known autoimmune human leukocyte antigen-dependent disorders, has a relatively increased prevalence in first-degree relatives. OBJECTIVE: To determine the prevalence of celiac disease in siblings of patients with confirmed celiac disease. METHODS: Siblings of confirmed celiac disease patients in our center were identified and enrolled in this study. Their serum immunoglobulin A and tissue transglutaminase antibody-enzyme-linked immunosorbent assay (anti-tissue transglutaminase, immunoglobulin A, and immunoglobulin G were measured and multiple endoscopic duodenal biopsy specimens were obtained with parental consensus. Celiac disease was confirmed by observation of characteristic histological changes. RESULTS: A total of 49 children (male, 29; female, 20; age, 2-16 years with confirmed celiac disease in a pediatric gastroenterology ward were studied from 1999 to 2006. We found 30 siblings (female, 16 all shared in both parents. The only measurement available was for immunoglobulin A tissue transglutaminase antibody. A duodenal biopsy was performed in all 30 siblings. Clinical findings such as abdominal pain, fatigue, growth retardation and diarrhea were found in 53.3% of the completely studied siblings, and positive serology without histological changes was identified in four cases. Both serology and biopsy (confirmed new cases were positive in 2 of the 30 siblings. CONCLUSION: High prevalence of celiac disease among siblings of patients with confirmed celiac disease necessitates serologic screening (and confirmatory biopsy if indicated in families having celiac disease. It is advantageous to diagnose the disease as soon as possible because early diagnosis and diet intervention may prevent serious complications such as growth retardation, short stature, chronic diarrhea, and malignancy.

Purpose Little information is available on genetic and epigenetic changes in duodenal adenocarcinomas. The purpose was to identify possible subsets of duodenal adenocarcinomas based on microsatellite instability (MSI), DNA methylation, mutations in the KRAS and BRAF genes, clinicopathologic features, and prognosis. Experimental Design Demographics, tumor characteristics and survival were available for 99 duodenal adenocarcinoma patients. Testing for KRAS and BRAF mutations, MSI, MLH1 methylation and CpG island methylator phenotype (CIMP) status was performed. A Cox proportional hazard model was built to predict survival. Results CIMP+ was detected in 27 of 99 (27.3%) duodenal adenocarcinomas, and was associated with MSI (P = 0.011) and MLH1 methylation (P CIMP− tumors. No BRAF V600E mutation was detected. Among the CIMP+ tumors, 15 (55.6%) were CIMP+/MLH1-unmethylated (MLH1-U). Kaplan-Meier analysis showed tumors classified by CIMP, CIMP/MLH1 methylation status or CIMP/MSI status could predict overall survival (OS; P = 0.047, 0.002, and 0.002, respectively), while CIMP/MLH1 methylation status could also predict time-to-recurrence (TTR; P = 0.016). In multivariate analysis, CIMP/MLH1 methylation status showed a significant prognostic value regarding both OS (P CIMP+/MLH1-U tumors had the worst OS and TTR. Conclusions Our results demonstrate existence of CIMP in duodenal adenocarcinomas. The combination of CIMP+/MLH1-U appears to be independently associated with poor prognosis in patients with duodenal adenocarcinomas. This study also suggests that BRAF mutations are not involved in duodenal tumorigenesis, MSI or CIMP development. PMID:22825585

Patients with duodenal ulcer have a reduced risk of developing gastric cancer compared to those without. Recently, the prostate stem cell antigen (PSCA) rs2294008 C>T polymorphism was found to be associated with different pathogenesis of duodenal ulcer and gastric cancer developments. However, whether PSCA rs2294008 C>T polymorphism is associated with severity of gastric mucosal atrophy is unclear. We examined the influence of the PSCA rs2294008 C>T polymorphism on susceptibility to H. pylori-related diseases and the relationships between PSCA polymorphism and gastric mucosal atrophy. PSCA rs2294008 C>T polymorphism was assessed in H. pylori-positive Japanese patients (n = 488) with noncardia gastric cancer (n = 193), gastric ulcer (n = 84), duodenal ulcer (n = 61), and atrophic gastritis (n = 150), as well as in H. pylori-negatives (n = 266). Frequency of PSCA rs2294008 C/C genotype in duodenal ulcer was 36.1%, which was significantly higher than those with gastric cancer (12.4%), gastric ulcer (19.0%), gastritis (10.7%), and H. pylori-negatives (19.5%) (p T polymorphism is associated with differing susceptibilities to H. pylori-associated diseases. The PSCA rs2294008 C>T polymorphism may be acting through induction of gastric mucosal atrophy, finally leading to development of gastric ulcer and gastric cancer in PSCA rs2294008 T allele carriers, but not duodenal ulcer. © 2014 John Wiley & Sons Ltd.

Some gastric cancers are Epstein-Barr virus associated. To assess the prevalence of Helicobacter pylori and viral co-infection in benign upper digestive diseases. One hundred and four outpatients were included in a prospective endoscopic-serologic study. Epstein-Barr virus immunoglobulin G (IgG), immunoglobulin M and viral capsid antigen titres were assayed with an ELISA test. Helicobacter pylori was determined by the modified Giemsa stain and by IgG-chemiluminescence. The overall prevalence of Helicobacter pylori was 56.7%. Duodenal ulcer patients were infected in 72.5 % of the cases, with the prevalence being 33.3% in functional dyspepsia (p = 0.0008) and 25.8% in reflux patients (p = 0.0001). Epstein-Barr virus IgG was detected in 70.1% of the whole group, 75% of duodenal ulcer patients, 51.2% of functional dyspepsia patients (p = 0.04) and 51.6% of the reflux disease cases (p = 0.04). Co-infection with both agents was detected in 60% of duodenal ulcer patients, 18.1% of functional dyspepsia (p = 0.00014) and 12.9% of reflux disease patients (p = 0.00012). Anti-viral IgG titre displayed a 31.7 ± 3.0 cut-off index in duodenal ulcer, 20.5 ± 3.5 in functional dyspepsia (p = 0.01) and 21.4 ± 3.6 in reflux cases (p = 0.03). Both Helicobacter pylori and Epstein-Barr virus, and co-infection with these agents, were significantly more prevalent in duodenal ulcer patients than in dyspeptic/reflux patients.

To determine the prevalence of celiac disease in children and adolescents with nonsyndromic intellectual disability, we investigated serum levels of tissue transglutaminase antibody and total IgA from 232 children with nonsyndromic intellectual disability and in a healthy control group of 239 children. Study participants who were positive for tissue transglutaminase antibody underwent a duodenal biopsy. A total of 3 patients in the nonsyndromic intellectual disability group (5.45%) and 1 in the control group (0.41%) had positive serum tissue transglutaminase antibody (P > .05). Duodenal biopsy confirmed celiac disease in only 1 patient who had nonsyndromic intellectual disability. In this present study, children with nonsyndromic intellectual disability did not exhibit a higher celiac disease prevalence rate compared with healthy controls. Therefore, we suggest that screening test for celiac disease should not be necessary as a part of the management of mild and moderate nonsyndromic intellectual disability. However, cases of severe nonsyndromic intellectual disability could be examined for celiac disease. © The Author(s) 2015.

Successful Management of Perforated Duodenal Diverticulitis With Intra-abdominal Drainage and Feeding Jejunostomy: A Case Report and Literature Review

Directory of Open Access Journals (Sweden)

Chin-Fan Chen

2008-08-01

Full Text Available We report the clinical experience of one patient with perforated duodenal diverticulitis who was successfully treated by intra-abdominal drainage and feeding jejunostomy. A 53-year-old male patient visited our hospital due to acute onset of abdominal pain and distension. Physical examination revealed tenderness over the epigastric area and right-lower quadrant of the abdomen without obvious rebound tenderness or muscle guarding. Duodenal diverticulitis with a retroperitoneal abscess was identified by abdominal computed tomography scan. Surgical intervention was performed after the failure of conservative treatment. The operative findings were compatible with perforated duodenal diverticulitis, and intra-abdominal drainage of retroperitoneal abscess with simultaneous feeding jejunostomy was undertaken. The patient was doing well at the 4-month postoperative follow-up visit. We suggest the use of a conservative operative method, as opposed to conventional diverticulectomy and duodenorrhaphy, as an alternative approach for the management of this disorder, especially when conservative treatment has failed.

Full Text Available Abstract Background Gastrointestinal bleeding is a common problem and its most common etiology is peptic ulcer disease. Ulcer rebleeding is considered a perilous complication for patients. To reduce the rate of rebleeding and to fasten the improvement of patients' general conditions, most emergency departments in Iran use H2-blockers before endoscopic procedures (i.e. intravenous omeprazole is not available in Iran. The aim of this study was to compare therapeutic effects of oral omeprazole and intravenous cimetidine on reducing rebleeding rates, duration of hospitalization, and the need for blood transfusion in duodenal ulcer patients. Methods In this clinical trial, 80 patients with upper gastrointestinal bleeding due to duodenal peptic ulcer and endoscopic evidence of rebleeding referring to emergency departments of Imam and Sina hospitals in Tabriz, Iran were randomly assigned to two equal groups; one was treated with intravenous cimetidine 800 mg per day and the other, with 40 mg oral omeprazole per day. Results No statistically significant difference was found between cimetidine and omeprazole groups in regards to sex, age, alcohol consumption, cigarette smoking, NSAID consumption, endoscopic evidence of rebleeding, mean hemoglobin and mean BUN levels on admission, duration of hospitalization and the mean time of rebleeding. However, the need for blood transfusion was much lower in omeprazole than in cimetidine group (mean: 1.68 versus 3.58 units, respectively; p Conclusion This study demonstrated that oral omeprazole significantly excels intravenous cimetidine in reducing the need for blood transfusion and lowering rebleeding rates in patients with upper gastrointestinal bleeding. Though not statistically significant (p = 0.074, shorter periods of hospitalization were found for omeprazole group which merits consideration for cost minimization.

Full Text Available Purpose: In the search of a new material to repair duodenal wounds, a trial was conducted to assess the behavior of human amniotic membrane in the repair of the duodenal wall in rats. METHODS: Fifty Wistar rats weighing between 250 and 350g, male, were submitted to duodenotomy and randomly distributed into two groups. Group A (n=8 had no treatment and was used as the control group. In Group B (n=42 the duodenal wound was treated with a patch of human amniotic membrane. RESULTS: All animals in Group A died. In Group B no changes were observed with regards to death or the formation of duodenal fistula. All animals presented peritoneal adherences in the region on the duodenal wall repair and intestinal obstruction was observed in two animals. Healing of the duodenal wall in the region of the patch took place progressively as the post-operatory period increased, with regeneration of the mucosa and of the smooth muscle layer. CONCLUSION: From the clinical standpoint, the amniotic membrane proved to be a biological tissue which served as a temporary seal and allowed the wound to heal by second-intention, with re-establishment of the duodenal wall structure.OBJETIVO: Na busca de um novo material para o reparo dos ferimentos duodenais, foi efetuado um estudo para avaliar o comportamento da membrana amniótica humana no reparo da parede duodenal em ratos.

Study with the purpose to examine the effects of duodenal switch (DS), regularly performed in morbidly obese patients, on biodistribution of sodium pertechnetate in several organs of rats. There was no early or late mortality in either rats groups. The values of percent radioactivity per gram of tissue (%ATI/g), showed no significant difference in liver, stomach, small bowel, duodenum, kidney, heart, bladder, bone and brain, when compared the DS rats with sham and controls rats.

Study with the purpose to examine the effects of duodenal switch (DS), regularly performed in morbidly obese patients, on biodistribution of sodium pertechnetate in several organs of rats. There was no early or late mortality in either rats groups. The values of percent radioactivity per gram of tissue (%ATI/g), showed no significant difference in liver, stomach, small bowel, duodenum, kidney, heart, bladder, bone and brain, when compared the DS rats with sham and controls rats. A postoperative significant increase (p<0.05) in mean %ATI/g levels was observed in spleen, pancreas and muscle in group DS rats, as compared to group S and C rats. In the lung there was an increase and in thyroid a decrease in mean %ATI/g of DS rats, when compared to sham rats (p<0.05).

Full Text Available Context Neurological symptoms have been well-documented in patients with celiac disease, nevertheless, the presumption of a greater prevalence of epilepsy in celiac patients remains controversial. Objectives To determine the frequency of celiac disease in children and adolescents with idiopathic or cryptogenic epilepsy. Methods A cross-sectional study. One hundred pediatric patients with non-symptomatic epilepsy were followed-up at two public pediatric neurology clinics in Salvador, Bahia, Brazil. Screening for celiac disease was performed by serial measurements of IgA anti-transglutaminase and IgA anti-endomysium antibodies, followed by bowel biopsy in positive cases. HLA DQ02 and DQ08 were investigated in seropositive individuals, assessing the type of seizures, the number of antiepileptic drugs used and the presence gastrointestinal symptoms. Results Three (3.0% patients tested anti-tTG-positive, two with normal duodenal mucosa (Marsh 0 and one with intraepithelial infiltrate (Marsh I. No villous atrophy of the duodenal mucosa (Marsh III celiac disease was found. Two patients tested positive for HLA DQ02; none were DQ08 positive. Conclusion The present study failed to prove the association between celiac disease and epilepsy.

Introduction: High morbidity rate, frequent relapses, and significant economic losses give reasons for highlighting the peptic ulcer disease as the most topical medical-statistical problem. The aim of the study is to assess the influence of the main risk factors on the course of gastric and duodenal peptic ulcer. Materials and methods: We formed up the risk groups consisted of patients with 12 modified (4) and regular (8) factors, each characterized with its own signs and gradations. We performed the quantitative evaluation of the factors and scored the signs thereof, the results of which were used for determination of the most informative ones. Results: Among the regular factors, we placed emphasis on gender, age, burdened heredity, and 0(I), Rh+ blood type. The risk of peptic ulcer in hereditary tainted young men of the working age with parental lineage (+2.3) and in males with 0(I) Rh+ blood type (+1.4) was proved. Helicobacter pylori (Hp) infection is a key contributor (a predictor of) to severity of the disease course (+9.7) among the modified risk factors. Negative effect of a concomitant pathology (+5.0), including hepatobiliary lesions (+3.8), hypertension (+4.0), and diabetes mellitus (+1.3) is also significant. Diet violation (+3.7), tobacco smoking (+3.2) and stress (+3.0) were ranked third. Conclusions: The results of quantitative evaluation of the factors scoring suggest of the underlying H.pylori infection (the significance of which is growing along with the growth of the disease incidence) and irrational diet as the most informatively important ones. We have established the direct dependence between the most important peptic ulcer risk factors, severity of the disease, and duration and periodicity of treatment thereof.

Previous structure-activity and pharmacologic studies with duodenal ulcerogens cysteamine and propionitrile implicating catecholamines in the pathogenesis of duodenal ulceration have now been followed up by dose- and time-response biochemical investigations to assess the importance of monoamines in the development of duodenal ulcers. The concentrations of norepinephrine (noradrenaline), dopamine, serotonin and their metabolites were measured in total brain, brain regions, stomach, duodenum, pancreas and adrenals in the rat. Turnover of catecholamines was determined in rats pretreated with the inhibitor of tyrosine hydroxylase alpha-methyl-p-tyrosine. The duodenal ulcerogens caused a dose- and time-dependent depletion of norepinephrine in virtually all the tissues examined. The effect was maximal 4 or 7 hr after cysteamine or propionitrile, and norepinephrine levels returned to normal in 24 hr. Dopamine changes were selective and often biphasic, e.g., elevation in adrenals, biphasic in brain cortex, hippocampus and midbrain, but uniformly decreasing in glandular stomach and duodenum. In the median eminence dopamine levels decreased by 181 and 324% at 15 and 30 min, respectively, after cysteamine, but neither dopamine nor 3,4-dihydroxyphenylacetic acid was modified in the periventricular nucleus. Serotonin levels were relatively stable, revealing slight elevations or no changes in most of the tissues. The turnover of norepinephrine was accelerated by both chemicals in virtually all brain regions, but dopamine turnover was affected only in a few areas, e.g., in the corpus striatum and medulla oblongata cysteamine decreased dopamine turnover, whereas propionitrile first (at 1 hr) accelerated then (at 8 hr) significantly suppressed it.(ABSTRACT TRUNCATED AT 250 WORDS)

A 68-year-old Japanese woman underwent radiotherapy for gastric lymphoma. Although lymphangiectasia was sparsely observed in the second portion of the duodenum before radiotherapy, the number of pinpoint white spots obviously increased after the treatment. Although the duodenal lymphangiectasia gradually progressed, the patient had no features of protein-losing enteropathy. This case highlights the importance of endoscopic observation of the duodenum after irradiation to the abdomen as radiotherapy may secondarily cause intestinal lymphangiectasia. PMID:28798810

Full Text Available BACKGROUND AND OBJECTIVE: Barrett's esophagus (BE is characterized by the transition of squamous epithelium into columnar epithelium with intestinal metaplasia. The increased number and types of immune cells in BE have been indicated to be due to a Th2-type inflammatory process. We tested the alternative hypothesis that the abundance of T-cells in BE is caused by a homing mechanism that is found in the duodenum. PATIENTS AND METHODS: Biopsies from BE and duodenal tissue from 30 BE patients and duodenal tissue from 18 controls were characterized by immmunohistochemistry for the presence of T-cells and eosinophils(eos. Ex vivo expanded T-cells were further phenotyped by multicolor analysis using flowcytometry. RESULTS: The high percentage of CD4(+-T cells (69±3% (mean±SEM/n = 17, by flowcytometry, measured by flowcytometry and immunohistochemistry, and the presence of non-activated eosinophils found in BE by immunohistochemical staining, were not different from that found in duodenal tissue. Expanded lymphocytes from these tissues had a similar phenotype, characterized by a comparable but low percentage of αE(CD103 positive CD4(+cells (44±5% in BE, 43±4% in duodenum of BE and 34±7% in duodenum of controls and a similar percentage of granzyme-B(+CD8(+ cells(44±5% in BE, 33±6% in duodenum of BE and 36±7% in duodenum of controls. In addition, a similar percentage of α4β7(+ T-lymphocytes (63±5% in BE, 58±5% in duodenum of BE and 62±8% in duodenum of controls was found. Finally, mRNA expression of the ligand for α4β7, MAdCAM-1, was also similar in BE and duodenal tissue. No evidence for a Th2-response was found as almost no IL-4(+-T-cells were seen. CONCLUSION: The immune cell composition (lymphocytes and eosinophils and expression of intestinal adhesion molecule MAdCAM-1 is similar in BE and duodenum. This supports the hypothesis that homing of lymphocytes to BE tissue is mainly caused by intestinal homing signals rather than to an

With the continuous improvement of liver transplantation technology, the survival rate of liver transplantation has been improved, but recurrent or de novo malignancy remains one of the major factors affecting the long-term survival of liver transplant recipients. A 45-year-old Chinese man had a plastic biliary stent placed on account of biliary anastomotic stenosis after 3 years of piggyback liver transplantation. He came to our hospital because of recurrent fever and jaundice for 2 weeks, and his carcinoembryonic antigen-199 had increased. The patient's duodenal papillary was cauliflower-like at endoscopic retrograde cholangiopancreatography to replace the biliary stent. He was initially suspected of having duodenal papillary carcinoma after liver transplantation. However, the pathology from endoscopic retrograde cholangiopancreatography and endoscopic ultrasound-guided biopsy showed inflammation. While awaiting the result of biopsy, his CA-199 decreased significantly after anti-infection and symptomatic treatment. The patient was diagnosed with biliary anastomotic stenosis and duodenal papillitis. He was discharged uneventfully; to date, there is no evidence of malignant tumor. We report this case to provide helpful information to clinicians about the management of the duodenal papilla cauliflower-like neoplasm after liver transplantation, which should be considered as inflammatory first. Perhaps our view can avoid the risk of bringing an excessive medical treatment and unnecessary economic burden to patients and their families. Copyright © 2018 Elsevier Inc. All rights reserved.

Autoradiographic localization of a gluten peptide during organ culture of human duodenal mucosa

1983-01-01

An 125I-labeled subfraction of Frazer's fraction III (molecular weight, 8,000) was added to the culture medium during organ culture of duodenal biopsies from two patients with celiac disease in exacerbation. The isotope-labeled gluten peptide was localized by autoradiography after 6, 12, and 24 h of culture. At 6 h, labeling was located mainly in the basal layers of the biopsies. The tissue was well preserved. After 12 h in culture, the labeling had spread to the lamina propria and the crypts. A few grains were located over enterocytes and desquamated cells. Moderate histological signs of toxicity were observed. After 24 h, there was marked toxic deterioration, comparable to that seen after culture with alpha-gliadin. Labeling had spread throughout the entire section. There seemed to be no specificity of the binding, for the entire section was affected. Culture with the identical gluten fraction, in the radionegative state, produced histological deterioration comparable to that seen after exposure to the isotope-labeled peptide. Gluten peptides are presented to the target cells in a unique way during organ culture, different from in vivo conditions. This may influence the results when the organ culture method is used to investigate the pathogenesis of celiac disease

An association between the triple-X syndrome (47,XXX) and gastrointestinal malformations is extremely rare. Most 47,XXX patients present with a normal phenotype, but genitourinary malformations have been described. We report a case of a child with 47,XXX and duodenal atresia. Antenatal ultrasound scan showed a dilated fetal stomach and upper part of the duodenum (double bubble phenomenon) at 31 weeks of gestation in a 31-year-old woman with polyhydramnion. The amniotic fluid karyotype showed 47,XXX. After a scheduled delivery, duodenal atresia was confirmed and treated with duodeno-duodenostomy. The possible association of gastrointestinal and genitourinary tract anomalies requires a detailed postnatal clinical investigation and ultrasonographic examination of the abdomen, retroperitoneum, and pelvis on all triple-X syndrome patients. 2007 Wiley-Liss, Inc.

Full Text Available Gastrointestinal carcinoid tumors are uncommon neuroendocrine tumours that may be associated with synchronous or metachronous primary tumours of other histological type, most frequently colorectal adenocarcinomas. Primary ovarian mucinous adenocarcinomas have been reported to coincide with few other ovarian tumours and minority of these tumours may occur in association with Lynch syndrome. However association of duodenal carcinoid with ovarian mucinous adenocarcinoma is distinctly unusual and, to our knowledge, has not been previously described. We report a case of occult metastasising duodenal atypical carcinoid that was incidentally detected during surgical intervention performed for left ovarian mucinous cystadenocarcinoma in a middle aged female. The carcinoid tumour was Stage IIIB with regional nodal metastasis and the ovarian tumour was Stage IA with low grade histology.

Department of Pediatrics No 2, National Pirogov Memorial Medical University Vinnitsya, Ukraine   Abstract Background .Diseases of the upper gastrointestinal tract in children occupy a leading place in the structure of gastroenterological diseases, including the  duodenal ulcer, which is the actual problem of modern medicine throughout the world, characterized by  the progressive growth. Establishing the role of H. pylori in the mechanisms of a number of diseases of the upper gastrointestinal tract changed the approach to the problem of this disease. An important role in the development of infectious-inflammatory process induced by H. pylori play TLR4, having reactivity to lipopolysaccharide of Gram-negative bacteria. Much attention is being paid to determine the effect of H. pylori in the regeneration  damaged of duodenal mucosa, which by means of growth factors, such as epidermal growth factor(EGF. EGF - a universal endogenous regulator of cell renewal, which accelerates migration and proliferation of the epithelium, enhances angiogenesis. The aim of our study was to evaluate the results of complex treatment in children with duodenal ulcer according to the dynamics of TLR4 and EGF in  blood serum. Materials and methods. The overall clinical group consisted of 54 children with duodenal ulcer aged 7-18 years. The control group consisted of 25 healthy children of similar age. The average age of patients was 13,3 ± 0,2 years.  The study used clinical, laboratory and instrumental  methods of  examination   used.  The content of  TLR 4 and EGF in serum were determined by ELISA. Results and discussion. Children who were under supervision, were allocated based on the severity of the disease and the presence of H. pylori infection. Among the patients  H. pylori (+ duodenal ulcer had 40 (74.07% children - 14 (25.93% patients had no H. pylori infection.

Coeliac disease: review of diagnosis and management.

Science.gov (United States)

Walker, Marjorie M; Ludvigsson, Jonas F; Sanders, David S

2017-08-21

Coeliac disease is an immune-mediated systemic disease triggered by exposure to gluten, and manifested by small intestinal enteropathy and gastrointestinal and extra-intestinal symptoms. Recent guidelines recommend a concerted use of clear definitions of the disease. In Australia, the most recent estimated prevalence is 1.2% in adult men (1:86) and 1.9% in adult women (1:52). Active case finding is appropriate to diagnose coeliac disease in high risk groups. Diagnosis of coeliac disease is important to prevent nutritional deficiency and long term risk of gastrointestinal malignancy. The diagnosis of coeliac disease depends on clinico-pathological correlation: history, presence of antitransglutaminase antibodies, and characteristic histological features on duodenal biopsy (when the patient is on a gluten-containing diet). Human leucocyte antigen class II haplotypes DQ2 or DQ8 are found in nearly all patients with coeliac disease, but are highly prevalent in the general population at large (56% in Australia) and testing can only exclude coeliac disease for individuals with non-permissive haplotypes. Adhering to a gluten free diet allows duodenal mucosal healing and alleviates symptoms. Patients should be followed up with a yearly review of dietary adherence and a health check. Non-coeliac gluten or wheat protein sensitivity is a syndrome characterised by both gastrointestinal and extra-intestinal symptoms related to the ingestion of gluten and possibly other wheat proteins in people who do not have coeliac disease or wheat allergy recognised by diagnostic tests.

Probably due to caffeine-induced gastric acid secretion, negative effects of coffee upon various upper-gastrointestinal diseases have been precariously accepted, despite the inadequate epidemiological evidence. Our aim is to evaluate the effect of coffee consumption on four major acid-related diseases: gastric ulcer (GU), duodenal ulcer (DU), reflux esophagitis (RE), and non-erosive reflux disease (NERD) based on the large-scale multivariate analysis. Of the 9,517 healthy adults, GU, DU, and RE were diagnosed by endoscopy, and NERD was diagnosed by the symptoms of heartburn and regurgitation without esophageal erosion. Associations between coffee consumption and the four disorders were evaluated, together with age, gender, body mass index (BMI), Helicobacter pylori (HP) infection status, pepsinogen I/II ratio, smoking, and alcohol. We further performed meta-analysis using the random effects model to redefine the relationship between coffee intake and peptic ulcer disease. The eligible 8,013 study subjects comprised of 5,451 coffee drinkers and 2,562 non-coffee drinkers. By univariate analysis, age, BMI, pepsinogen I/II ratio, smoking, and alcohol showed significant associations with coffee consumption. By multiple logistic regression analysis, positively correlated factors with significance were HP infection, current smoking, BMI, and pepsinogen I/II ratio for GU; HP infection, pepsinogen I/II ratio, and current smoking for DU; HP non-infection, male, BMI, pepsinogen I/II ratio, smoking, age, and alcohol for RE; younger age, smoking, and female for NERD. The meta-analyses could detect any association of coffee consumption with neither GU nor DU. In conclusion, there are no significant relationship between coffee consumption and the four major acid-related upper gastrointestinal disorders.

1996-01-01

The purpose of this study was to develop an effective diagnostic method for infantile jaundice. 99m Tc-EHIDA hepatobiliary scintigraphy and determination of bilixanthine from duodenal drainage were carried out in 33 infants with persistent jaundice. The final diagnosis was confirmed by surgical operation, pathology or clinical follow-up. For diagnosing biliary atresia, the sensitivity and specificity of scintigraphy were 100% and 72.7% respectively and those of bilixanthine measurement were 100% and 95.5%. Hepatobiliary scintigraphy may be a sensitive, simple, safe and noninvasive method for differentiating infantile jaundice. Duodenal bilixanthine determination may improve the specificity in the case without intestinal radioactivity in scintigram

Increasing apoA-I synthesis may improve HDL functionality and lower CVD risk. As theobromine and fat increase fasting apoA-I concentrations, and the intestine is involved in apoA-I production, the acute effects of both were studied on duodenal gene transcription to better understand underlying mechanisms. In this crossover study, 8 healthy men received once a low fat (LF) meal, a LF meal plus theobromine (850 mg), or a high fat (HF) meal. Five hours after meal intake duodenal biopsies were taken for microarray analysis. Theobromine and HF consumption did not change duodenal apoA-I expression. Theobromine did not change gene expression related to lipid and cholesterol metabolism, whereas those related to glycogen/glucose breakdown were downregulated. HF consumption increased gene expression related to lipid and cholesterol uptake and transport, and to glucose storage, while it decreased those related to glucose uptake. Furthermore, genes related to inflammation were upregulated, but inflammation markers in plasma were not changed. In healthy men, acute theobromine and fat consumption did not change duodenal apoA-I mRNA, but inhibited expression of genes related to glucose metabolism. Furthermore, HF intake activated in the duodenum expression of genes related to lipid and cholesterol metabolism and to inflammation.

Rabbit duodenal brush-border membrane vesicles were treated in vitro with deoxycholate, glycodeoxycholate, or taurodeoxycholate. Intravesicular [14C]glucose space at equilibrium, 0.54 microliters/mg protein, was reduced by exposure to the three bile salts in a concentration (0.1-5.0 mM)-dependent manner, equatable with increased membrane fragility. Net proton permeability (Pnet), determined by acridine orange fluorescence quenching, was increased from 6.3 x 10(-4) cm/sec in untreated vesicles, by approximately 120, 150, and 170%, by treatment with bile salts at 0.1, 0.5 and 1.0 mM, respectively. The three bile salts were equipotent. The increases in membrane fragility and Pnet were not accompanied by significant increases in membrane fluidity, as assessed from steady-state and time-resolved diphenylhexatriene fluorescence anisotropy. The data demonstrate direct effects of bile salts on duodenal apical membrane fragility and proton permeability that are likely to be early events in bile salt-induced mucosal damage

Full Text Available Background. Helicobacter pylori (HP infection and nonsteroidal anti-inflammatory drugs (NSAID use are considered the main risk to develop peptic ulcer disease (PUD. However, PUD also occurs in the absence of HP infection and/or NSAID use. Recently, we have found evidence that Epstein-Barr virus (EBV reactivation increases the risk to develop premalignant and malignant gastric lesions. Objective. To study a possible association between EBV and PUD. Methods. Antibodies against an EBV reactivation antigen, HP, and the HP virulence factor CagA were measured in sera from 207 Mexican subjects, controls (healthy individuals, n = 129, and PUD patients (n = 78, 58 duodenal and 20 gastric ulcers. Statistical associations were estimated. Results. Duodenal PUD was significantly associated with high anti-EBV IgG titers (p = 0.022, OR = 2.5, while anti-EBV IgA was positively associated with gastric PUD (p = 0.002, OR = 10.1. Conclusions. Our study suggests that EBV reactivation in gastric and duodenal epithelium increases the risk to develop PUD.

Full Text Available Acid peptic disease (APD is a worldwide health problem. It includes a variety of inflammatory and ulcerative lesions involving esophagus, stomach and duodenum. The disease condition may persist with multiple symptoms, one of them being dyspepsia. The object of the present study was to determine the frequency and seasonal variations of APD in patients presenting with dyspeptic symptoms. This observational study was carried out at the endoscopy unit in Baqai Medical University from December 2003 to December 2010, over a period of seven years. The evolution of APD frequency remained equivocal throughout the study period. However, a decline was noted in the frequency of peptic ulcer disease (PUD especially for gastric and duodenal ulcer cases but a rise during autumn and winter seasons was also noted in duodenal ulcer cases.

To postoperative endoscopic retrograde cholangiopancreatography (ERCP) failure, we describe a modified Rendezvous technique for an ERCP in patients operated on for common bile duct stone (CBDS) having a T-tube with retained CBDSs. Five cases operated on for CBDSs and having retained stones with a T-tube were referred from other hospitals located in or around Istanbul city to the ERCP unit at the Haydarpasa Numune Education and Research Hospital. Under sedation anesthesia, a sterile guide-wire was inserted via the T-tube into the common bile duct (CBD) then to the papilla. A guide-wire was held by a loop snare and removed through the mouth. The guide-wire was inserted into the sphincterotome via the duodenoscope from the tip to the handle. The duodenoscope was inserted down to the duodenum with a sphincterotome and a guide-wire in the working channel. With the guidance of a guide-wire, the ERCP and sphincterotomy were successfully performed, the guide-wire was removed from the T-tube, the stones were removed and the CBD was reexamined for retained stones by contrast. An ERCP can be used either preoperatively or postoperatively. Although the success rate in an isolated ERCP treatment ranges from up to 87%-97%, 5%-10% of the patients require two or more ERCP treatments. If a secondary ERCP fails, the clinicians must be ready for a laparoscopic or open exploration. A duodenal diverticulum is one of the most common failures in an ERCP, especially in patients with an intradiverticular papilla. For this small group of patients, an antegrade cannulation via a T-tube can improve the success rate up to nearly 100%. The modified Rendezvous technique is a very easy method and increases the success of postoperative ERCP, especially in patients with large duodenal diverticula and with intradiverticular papilla.

Infection by Helicobacter pylori is associated with the development of several gastroduodenal diseases, including gastritis, peptic ulcer disease (gastric ulcers and duodenal ulcers), and gastric adenocarcinoma. Although a number of putative virulence factors have been reported for H. pylori, there are conflicting results regarding their association with specific H. pylori-related diseases. In this work, we investigated the presence of virB11 and cagT, located in the left half of the cag pathogenicity island (cagPAI), and the jhp917-jhp918 sequences, components of the dupA gene located in the plasticity zone of H. pylori, in Brazilian isolates of H. pylori. We also examined the association between these genes and H. pylori-related gastritis, peptic ulcer disease, and gastric and duodenal ulcers in an attempt to identify a gene marker for clinical outcomes related to infection by H. pylori. The cagT gene was associated with peptic ulcer disease and gastric ulcers, whereas the virB11 gene was detected in nearly all of the samples. The dupA gene was not associated with duodenal ulcers or any gastroduodenal disease here analyzed. These results suggest that cagT could be a useful prognostic marker for the development of peptic ulcer disease in the state of São Paulo, Brazil. They also indicate that cagT is associated with greater virulence and peptic ulceration, and that this gene is an essential component of the type IV secretion system of H. pylori.

A 63-year-old woman with abdominal pain was referred to our hospital. Her pancreatic enzymes were elevated, and an abdominal computed tomography (CT) scan showed an enlarged pancreas, consistent with pancreatitis, and gas collection containing an impacted stone adjacent to Vater's papilla. This finding raised the suspicion of a duodenal diverticulum. A subsequent ERCP showed a juxtapapillary duodenal diverticulum (JPDD) filled with calculi and pus. The pancreatitis improved with 2 weeks of conservative treatment. Subsequently, the patient underwent resection of the uterus and bilateral adnexa to remove a large ovarian cyst that was also identified on the admission CT scan. On the third postoperative day, she developed abdominal pain and vomiting. CT revealed small bowel obstruction caused by an enterolith expelled from JPDD. Enterotomy was performed to remove the stone. To our knowledge, only three similar cases have been previously reported in Japan.

Clinicopathological characteristics of duodenal epithelial neoplasms: Focus on tumors with a gastric mucin phenotype (pyloric gland-type tumors.

Full Text Available Epithelial tumors less commonly occur in the duodenum than in the stomach or large intestine. The clinicopathological characteristics of duodenal epithelial tumors remain a matter of debate. We therefore studied resected specimens to investigate the clinicopathological characteristics of duodenal epithelial tumors.Among duodenal epithelial tumors resected endoscopically or surgically in our hospital, we studied the clinicopathological characteristics of 110 adenomas or intramucosal carcinomas. The grade of atypia of all tumors was classified into 3 groups according to the World Health Organization (WHO 2010 classification. The tumors were immunohistochemically evaluated to determine the frequency of differentiation toward fundic glands.As for patient characteristics, there were 76 men (75.2% and 25 women (24.8%, with a median age of 65 years (range, 34 to 84. The tumors most commonly arose in the first to second part of the duodenum. Many lesions were flat, and the median tumor diameter was 8.0 mm. The lesions were classified into 2 types according to mucin phenotype: intestinal-type tumors (98 lesions, 89.1% and gastric-type tumors (12 lesions, 10.9%. Intestinal-type tumors were subdivided into 2 groups: tubular-type tumors (91 lesions, 82.7% and tubulovillous-type tumors (7 lesions, 6.4%. Gastric-type tumors were classified into 2 types: foveolar type (3 lesions, 2.7% and pyloric gland-type (PG tumors (9 lesions, 8.2%. The grade of atypia was significantly higher in gastric-type tumors (p<0.01. PG tumors were gastric-type tumors characterized by pyloric glands and findings suggesting differentiation toward fundic glands.About 10% of the duodenal tumors had a gastric-type mucin phenotype. Gastric-type tumors showed high-grade atypia. In particular, PG tumors showed similarities to PG tumors of the stomach, such as differentiation toward fundic glands.

Purpose: To characterize the rates of acute and late duodenal and other gastrointestinal (GI) toxicities among patients treated for cervical and endometrial cancers with extended-field intensity modulated radiation therapy (EF-IMRT) to the paraaortic nodes and to analyze dose-volume relationships of GI toxicities. Methods and Materials: Fifty-three patients with endometrial or cervical cancer underwent EF-IMRT to the paraaortic nodes, of whom 46 met the inclusion criteria for GI toxicity and 45 for duodenal toxicity analysis. The median prescribed dose to the paraaortic nodes was 54 Gy (range, 41.4-65 Gy). The 4 duodenal segments, whole duodenum, small bowel loops, peritoneum, and peritoneum plus retroperitoneal segments of colon were contoured retrospectively, and dosimetric analysis was performed to identify dose-volume relationships to grade ≥3 acute (<90 day) and late (≥90 day) GI toxicity. Results: Only 3/46 patients (6.5%) experienced acute grade ≥3 GI toxicity and 3/46 patients (6.5%) experienced late grade ≥3 GI toxicity. The median dose administered to these 6 patients was 50.4 Gy. One of 12 patients who received 63 to 65 Gy at the level of the renal hilum experienced grade 3 GI toxicity. Dosimetric analysis of patients with and without toxicity revealed no differences between the mean absolute or fractional volumes at any 5-Gy interval between 5 Gy and the maximum dose. None of the patients experienced duodenal toxicity. Conclusions: Treatment of paraaortic nodes with IMRT is associated with low rates of GI toxicities and no duodenal-specific toxicity, including patients treated with concurrent chemotherapy. This technique may allow sufficient dose sparing of the bowel to enable safe dose escalation to at least 65 Gy.

Is the Diagnosis of Celiac Disease Possible Without Intestinal Biopsy?

Directory of Open Access Journals (Sweden)

Maha Shomaf

2017-08-01

Full Text Available Background: Coeliac disease is defined as a state of immune-mediated hyper-responsiveness to dietary gluten from wheat, barley, or rye in genetically predisposed individuals that results in tissue damage. The diagnosis is made by microscopic examination of a small intestinal biopsy, although serological testing for antibodies against tissue transglutaminase and deamidated gliadin peptide can be of great advantage. It has been suggested that duodenal biopsy can be avoided in patients with high levels of the tissue transglutaminase antibody, since a relationship has been found to be present between tissue transglutaminase antibody titres and coeliac disease. Aims: To study the correlation between tissue transglutaminase titre and small intestinal biopsy findings in patients with coeliac disease. Study Design: Diagnostic accuracy study. Methods: Ninety-five cases of patients diagnosed with coeliac disease and with positive serum tissue transglutaminase titres were retrieved from the Jordan University Hospital archives between December 2014 and December 2015. All the cases were classified according to the Marsh classification. Results: Ninety-five cases with a positive titre for the antibody were included in this study, 73 (76.8% of them were females and 22 cases (23.2% were males. The age of the patients ranged between 4 and 75 years with a mean age ± standard deviation of 32.3±14.7. The sensitivity was the highest in Marsh IIIC and lowest in Marsh IIIA (95% versus 68% respectively. The specificity was moderate (76% for all subtypes of Marsh III. Conclusion: This study showed a positive correlation between the tissue transglutaminase titre and the degree of duodenal damage (Marsh IIIC in patients with coeliac disease. In the presence of high tissue transglutaminase levels, duodenal biopsy might not be always necessary for diagnosis, particularly in symptomatic patients

Possible mechanisms underlying diabetes remission following Roux-en-Y gastric bypass (RYGB) include eradication of putative factor(s) with duodenal-jejunal bypass. The objective of this study is to observe the effects of duodenal-jejunal transit on glucose tolerance and diabetes remission in gastric bypass rat model. In order to verify the effect of duodenal-jejunal transit on glucose tolerance and diabetes remission in gastric bypass, 22 type 2 diabetes Sprague-Dawley rat models established through high-fat diet and low-dose streptozotocin (STZ) administered intraperitoneally were assigned to one of three groups: gastric bypass with duodenal-jejunal transit (GB-DJT n = 8), gastric bypass without duodenal-jejunal transit (RYGB n = 8), and sham (n = 6). Body weight, food intake, blood glucose, as well as meal-stimulated insulin, and incretin hormone responses were assessed to ascertain the effect of surgery in all groups. Oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were conducted three and 7 weeks after surgery. Comparing our GB-DJT to the RYGB group, we saw no differences in the mean decline in body weight, food intake, and blood glucose 8 weeks after surgery. GB-DJT group exhibited immediate and sustained glucose control throughout the study. Glucagon-like peptide 1 (GLP-1) and gastric inhibitory polypeptide (GIP) levels were also significantly increased from preoperative level in the GB-DJT group (p transit does not impede glucose tolerance and diabetes remission after gastric bypass in type-2 diabetes Sprague-Dawley rat model.

Full Text Available Background Foreign body ingestion is a relatively common in children. Most ingested foreign bodies spontaneously pass out of the body via the gastrointestinal (GI system but sharp materials may perforate the GI tract and need to surgical intervention. Case Presentation  The patient was a 9-year-old girl with progressive abdominal pain for one month and admitted with acute abdomen impression. She underwent esogastroduodenoscopy (EGD due to severe epigastric tenderness. Upper GI endoscopy revealed duodenal ulceration and perforation by a toothpick while she had no history of foreign body ingestion. Toothpick was removed by endoscopy. She was successfully managed conservatively and had no abdominal pain during the one month follow-up period. Conclusion We recommend the endoscopic approach as the preferable method for the extraction of duodenal foreign bodies in children, even in the case of intestinal perforation.

Full Text Available Brunner’s gland hamartomas are small benign lesions that are most commonly found in the bulb of the duodenum. They are very uncommon, and most are found incidentally during upper gastrointestinal series or esophagogastroduodenoscopy. The lesions tend to be asymptomatic, but patients may present with symptoms of duodenal obstruction or hemorrhage secondary to ulceration. Histologically, a Brunner's gland hamartoma consists of the components of Brunner's gland cells, as well as glandular, adipose and muscle cells. In this study, we report the case of a 30-year-old man who presented with upper gastrointestinal bleeding and obstructive symptoms due to a giant Brunner's gland hamartoma in the duodenal bulb. The hamartoma was successfully removed by endoscopic resection. No significant complications were observed. Microscopically, the lesion was found to be entirely composed of variable Brunner's glands and adipocytes.

Celiac disease (CD), a systemic autoimmune disorder that typically involves duodenal mucosa, can also affect other intestinal areas. Duodenal and oral mucosa organ culture has already been demonstrated as a reliable procedure to identify CD. The present study investigated gluten-dependent immunological activation of colonic mucosa in CD patients. We took advantage of the numerous colonoscopies performed for various clinical conditions or only for defensive medicine. Forty-four patients with gastrointestinal symptoms or in need of colorectal cancer screening were divided into patients with serum anti-endomysium (EMA) and anti-tissue transglutaminase (anti-tTG) antibody positive results (Group A), patients with serum antibody negative results (Group B), and patients with inflammatory bowel disease (IBD) (Group C). The autoantibodies EMA and anti-tTG were evaluated in supernatants of cultured sigmoid and duodenal biopsies from patients on a gluten-containing diet. In Group A, EMA and anti-tTG resulted positive in all duodenal culture supernatants. In sigmoid culture supernatants, EMA and anti-tTG were detected in 12/16 (75 %) and 13/16 (81.3 %) patients, respectively. In Group B, none of the 17 patients showed EMA and anti-tTG positive results in both duodenal and sigmoid cultures. In Group C, all 11 patients presented EMA negative results in sigmoid cultures. Only in one patient, anti-tTG were detectable in the sigmoid culture supernatant, as expected in cases of IBD. Data confirm that the gluten-dependent immunological activation affects more intestinal tracts with different degrees of involvement, suggesting that the organ culture of colonic biopsies could represent a new tool to opportunistically detect CD.

Full Text Available This randomized, single-blind, parallel group study was conducted to compare omeprazole with ranitidine for the treatment of symptoms associated with gastroesophageal reflux disease (GERD, uncomplicated duodenal ulcer (DU or both. After baseline assessments, patients were randomized to receive daily treatment with either 20 mg omeprazole or 300 mg ranitidine for four weeks. In total, 1481 patients (1001 omeprazole, 480 ranitidine with a diagnosis of GERD (n=904 and/or DU (n=577, confirmed by endoscopy or barium meal and reporting moderate to severe symptoms, were included in the analyses. The seventy of overall daytime symptoms reported by the omeprazole group at clinic visits was lower than that reported by the ranitidine group at week 2 for the entire patient group (P=0.0002 and at both weeks 2 and 4 for the subgroup of patients with GERD (P=0.0001 and P=0.001, respectively. The severity of overall night-time symptoms reported by the omeprazole group was lower than that reported by the ranitidine group at week 4 for all patients as a whole (P=0.042 and at both weeks 2 and 4 for the subgroup of patients with GERD (P=0.035 and P=0.010, respectively. There were no significant differences in reports of adverse events. In the omeprazole group, 19% of patients at week 2 and 15% of patients at week 4 reported adverse events, while the corresponding results from the ranitidine group were 21% and 11%. In conclusion, patients with GERD, DU or both treated with omeprazole 20 mg daily for four weeks showed statistically significant reductions in symptoms compared with patients treated with ranitidine 300 mg daily for the same period of time. The percentage of patients with any remaining daytime symptoms was 12% lower in the omeprazole group compared with the ranitidine group at week 2, and 7% lower at week 4. Five per cent fewer patients in the omeprazole group experienced night-time symptoms at either week 2 or week 4.

Full Text Available Introduction. Primary duodenal adenocarcinoma is an infrequent tumor both in our environment and in the world. There is no conclusive evidence on its epidemiology, diagnostic criteria, treatment or prognosis. Clinical case. We report a 77 year-old female patient, of mixed racial origin, native of Cusco (Peru who consulted for abdominal pain, weight loss, nausea, postprandial vomiting and bloating of three months course. At the time of examination she had second to third degree protein malnutrition with a BMI of 16.88 kg/m2, signs of moderate to severe chronic anemia and an 8 cm abdominal tumor in the epigastrium and right hypochondrium. The multislice spiral abdominal CT and ultrasonography revealed the presence of a solid tumor in the second portion of the duodenum. The patient was submitted to a gastroenterostomy without tumor resection. Biopsy confirmed tubular adenocarcinoma. Furthermore, no other primary tumors were found in the stomach, pancreas, biliary tree and colon. The patient was stabilized and was treated with 5-fluorouracil, irinotecan and leucovorin. Literature review. The article includes a brief review on the diagnosis, treatment and prognosis of this condition. Discussion. Management is not straightforward. There is little literature on the subject leaving decisions up to the attending physician’s criteria. We believe that all cases of rare diseases should be studied in depth, give rise to a thorough review of literature and, above all, be brought to the attention of the medical community.

Stereotactic body radiation therapy (SBRT) achieves excellent local control for locally advanced pancreatic cancer (LAPC), but may increase late duodenal toxicity. Volumetric-modulated arc therapy (VMAT) delivers intensity-modulated radiation therapy (IMRT) with a rotating gantry rather than multiple fixed beams. This study dosimetrically evaluates the feasibility of implementing duodenal constraints for SBRT using VMAT vs IMRT. Non–duodenal sparing (NS) and duodenal-sparing (DS) VMAT and IMRT plans delivering 25 Gy in 1 fraction were generated for 15 patients with LAPC. DS plans were constrained to duodenal D{sub max} of<30 Gy at any point. VMAT used 1 360° coplanar arc with 4° spacing between control points, whereas IMRT used 9 coplanar beams with fixed gantry positions at 40° angles. Dosimetric parameters for target volumes and organs at risk were compared for DS planning vs NS planning and VMAT vs IMRT using paired-sample Wilcoxon signed rank tests. Both DS VMAT and DS IMRT achieved significantly reduced duodenal D{sub mean}, D{sub max}, D{sub 1cc}, D{sub 4%}, and V{sub 20} {sub Gy} compared with NS plans (all p≤0.002). DS constraints compromised target coverage for IMRT as demonstrated by reduced V{sub 95%} (p = 0.01) and D{sub mean} (p = 0.02), but not for VMAT. DS constraints resulted in increased dose to right kidney, spinal cord, stomach, and liver for VMAT. Direct comparison of DS VMAT and DS IMRT revealed that VMAT was superior in sparing the left kidney (p<0.001) and the spinal cord (p<0.001), whereas IMRT was superior in sparing the stomach (p = 0.05) and the liver (p = 0.003). DS VMAT required 21% fewer monitor units (p<0.001) and delivered treatment 2.4 minutes faster (p<0.001) than DS IMRT. Implementing DS constraints during SBRT planning for LAPC can significantly reduce duodenal point or volumetric dose parameters for both VMAT and IMRT. The primary consequence of implementing DS constraints for VMAT is increased dose to other organs at

We are reporting the first-to our knowledge-case of duodenal Plexiform Fibromyxoma causing obscure upper gastrointestinal bleeding. Plexiform fibromyxoma triggered recurrent upper gastrointestinal bleeding episodes in a 63-year-old man who remained undiagnosed, despite multiple hospitalizations, extensive diagnostic workups and surgical interventions (including gastrectomies), for almost 17 years. During hospitalization for the last bleeding episode, an upper gastrointestinal endoscopy revealed an intestinal hemorrhagic nodule. The lesion was deemed unresectable by endoscopic means. An abdominal computerized tomography disclosed no further lesions and surgery was decided. The lesion at operation was found near the edge of the duodenal stump and treated with pancreas-preserving duodenectomy (1st and 2nd portion). Postoperative recovery was mainly uneventful and a 20-month follow-up finds the patient in good health with no need for blood transfusions.Plexiform fibromyxomas stand for a rare and widely unknown mesenchymal entity. Despite the fact that they closely resemble other gastrointestinal tumors, they distinctly vary in clinical management as well as the histopathology. Clinical awareness and further research are compulsory to elucidate its clinical course and prognosis.

Does Ramadan Fasting Increase duodenal ulcer perforation?

Directory of Open Access Journals (Sweden)

Abdoulhossein Davoodabadi

2016-03-01

Full Text Available Introduction: In Ramadan, healthy adult Muslims are obliged to fast. Prolonged fasting increase gastric acid and pepsin levels, which promote the risk of duodenal ulcer perforation (DUP. Effects of Ramadan fasting on DUP have not been thoroughly studied yet, and the limited number of studies investigating the impact of Ramadan fasting on DUP yielded discrepant results. This study aimed to evaluate DUP frequency during Ramadan 2011-2015 and compare it with other months. Methods: This cross-sectional study was performed in 82 patients undergoing surgery due to DUP during July 2011-September 2015. The demographics, history of addiction, use of nonsteroidal and antiinflammatory drugs, previous history of acid peptic disease, as well as complications and outcomes of treatment were recorded and analyzed, and the obtained results were compared between Ramadan and other lunar months. Results: The majority of patients were male (86.6%, 71 patients, with a mean age of 43.9±16.5 years (age range: 20-75 years. Male to female ratio was 6:1. Cases with less than 30 years of age were less frequent (22%, 18 patients. DUP was more frequent during Rajab with nine cases (11%, while during Ramadan, six cases were reported, the difference between Ramadan and other months regarding the incidence of DUP was not significant (P=0.7. Risk factors such as smoking (60% and addiction (44%; especially to crystal and crack were noted. Consumption of nonsteroidal antiinflammatory drugs in 20 (24% patients, and use of antacids in 17 (25% patients. Distribution of DUP in different blood types was as follows: O+=41%, A+=28%, B+=23%, AB=5%, and O-=3%; moreover, post-operative Helicobacter pylori antibody was present in 67% of the patients. Conclusion: Ramadan fasting did not escalate DUP incidence, and those with DUP risk factors can fast with the use of antacids.

We aimed to assess the effects of either glutamine or an isonitrogenous protein mixture on duodenal protein metabolism in humans in the fed state. Twenty-four healthy volunteers were randomly included in 2 groups. Each volunteer was studied on 2 occasions in a random order and received, during 5 h, either an enteral infusion of maltodextrins alone (0.25 g · kg⁻¹ · h⁻¹; both groups) that mimicked a carbohydrate fed state or maltodextrins with glutamine (group 1) or an isonitrogenous (22.4 mg N · kg⁻¹ · h⁻¹) protein powder (group 2). Simultaneously, a continuous intravenous infusion of ¹³C-leucine and ²H₅-phenylalanine (both 9 μmol · kg⁻¹ · h⁻¹) was performed. Endoscopic duodenal biopsies were taken. Leucine and phenylalanine enrichments were assessed by using gas chromatography-mass spectrometry in duodenal proteins and the intracellular free amino acids pool to calculate the mucosal fractional synthesis rate (FSR). Proteasome proteolytic activities and phosphokinase expression were assessed by using specific fluorogenic substrates and macroarrays, respectively. The FSR and proteasome activity were not different after the glutamine supply compared with after maltodextrins alone. In contrast, the FSR increased (1.7-fold increase; P protein-powder delivery without modification of total proteasome activity. The protein powder increased insulinemia, PI3 kinase, and erk phosphorylation but did not affect the mammalian target of rapamycin (mTOR) pathway and mitogen-activated protein kinase signal-integrating kinase 1 phosphorylation. A trend for an increase of eukaryotic translation initiation factor 4E phosphorylation was observed (P = 0.07). In the carbohydrate fed state, enteral proteins but not glutamine increased duodenal protein synthesis through an mTOR independent pathway in humans.

Celiac disease is an autoimmune disorder induced by gluten in genetically susceptible individuals. It can result in intraintestinal and extraintestinal manifestations of disease including diarrhea, weight loss, anemia, osteoporosis, or lymphoma. Diagnosis of celiac disease is made through initial serologic testing and then confirmed by histopathologic examination of duodenal biopsies. Generally celiac disease is a benign disorder with a good prognosis in those who adhere to a gluten-free diet. However, in refractory disease, complications may develop that warrant additional testing with more advanced radiologic and endoscopic methods. This article reviews the current strategy to diagnose celiac disease and the newer modalities to assess for associated complications. Copyright © 2016 Elsevier Inc. All rights reserved.

Rare Case of Duodenal Metastasis From Pulmonary Squamous Cell Carcinoma

Directory of Open Access Journals (Sweden)

Zain Memon DO

2017-10-01

Full Text Available Pulmonary squamous cell carcinoma is the second most common non–small cell malignancy of the lung. It commonly metastasizes to the adrenal glands, bone, liver, brain, and kidneys. Most occurrences of metastatic squamous cell carcinoma involving the gastrointestinal tract originate from primary lung tumors. Metastasis to the duodenum, however, is exceedingly rare, with very few cases of stomach or duodenal involvement described in the literature. We report the case of a patient with stage IV pulmonary squamous cell carcinoma metastasizing to the duodenum with an uncommon presentation to add to the paucity of literature available regarding this rare finding.

Full Text Available Thyroid storm is a rare and life-threatening complication of thyrotoxicosis that requires prompt treatment. Thyroid storm is also known to be associated with precipitating events. The simultaneous treatment of thyroid storm and its precipitant, when they are recognized, in a patient is recommended; otherwise such disorders, including thyroid storm, can exacerbate each other. Here we report the case of a thyroid storm patient (a 55-year-old Japanese male complicated with a perforated duodenal ulcer. The patient was successfully treated with intensive treatment for thyroid storm and a prompt operation. Although it is believed that peptic ulcer rarely coexists with hyperthyroidism, among patients with thyroid storm, perforation of a peptic ulcer has been reported as one of the causes of fatal outcome. We determined that surgical intervention was required in this patient, reported despite ongoing severe thyrotoxicosis, and reported herein a successful outcome.

2010-10-01

Conclusion: In very proximal high atresia, the extent of tapering is limited by the proximity of the ligament of Treitz. Duodenal derotation provides better access to the high atresia. The results of this limited experience suggest that the DDETJ procedure could provide an alternative therapy in patients with high jejunal atresia.

Gastrointestinal bypass surgeries that result in rerouting and subsequent exclusion of nutrients from the duodenum appear to rapidly alleviate hyperglycemia and hyperinsulinemia independent of weight loss. While the mechanism(s) responsible for normalization of glucose homeostasis remains to be fully elucidated, this rapid normalization coupled with the well-known effects of vagal inputs into glucose homeostasis suggests a neurohormonally mediated mechanism. Our results show that duodenal bypass surgery on obese, insulin-resistant Zucker fa/fa rats restored insulin sensitivity in both liver and peripheral tissues independent of body weight. Restoration of normoglycemia was attributable to an enhancement in key insulin-signaling molecules, including insulin receptor substrate-2, and substrate metabolism through a multifaceted mechanism involving activation of AMP-activated protein kinase and downregulation of key regulatory genes involved in both lipid and glucose metabolism. Importantly, while central nervous system-derived vagal nerves were not essential for restoration of insulin sensitivity, rapid normalization in hepatic gluconeogenic capacity and basal hepatic glucose production required intact vagal innervation. Lastly, duodenal bypass surgery selectively altered the tissue concentration of intestinally derived glucoregulatory hormone peptides in a segment-specific manner. The present data highlight and support the significance of vagal inputs and intestinal hormone peptides toward normalization of glucose and lipid homeostasis after duodenal bypass surgery.

The first-degree relatives (FDRs) of patients with coeliac disease are the main risk group for disease development. The study aims to evaluate the screening strategy in FDRs with negative coeliac serology based on human leukocyte antigen (HLA) genotyping, followed by duodenal biopsy, and to analyze the prevalence of gastrointestinal symptoms and the influence of gluten intake. Adult FDRs with negative coeliac serology were invited to participate (n = 205), and a total of 139 completed the study protocol. HLA genotyping, transglutaminase antibody assessment, and duodenal biopsy were performed. Symptomatology was assessed using questionnaires during the various phases of dietary modification (baseline diet, gluten-free diet, and gluten overload). The study included 139 participants (mean age, 42 years; 53.2% women). HLA-DQ2/8 was positive in 78.4% of the participants (homozygous, 15.1%; heterozygous, 63.3%). Histopathological alterations were noted in 37.1% of participants who underwent duodenal biopsy (Marsh I, 32.7%; Marsh IIIa, 4.4%). At baseline, symptoms were observed in 45.7% of the participants, and the proportion decreased to 24.5% after the gluten-free diet (P < 0.001). Symptoms were not associated with the presence of histological alterations or genetic risk. However, younger age (odds ratio [OR] = 0.91), female sex (OR = 2.9), and the presence of autoimmune disorders (OR = 2.8) were independently associated with a significant symptom response to the gluten-free diet. Duodenal lymphocytosis and atrophy are frequently noted in FDRs, despite negative serological markers. In addition, gastrointestinal symptoms are commonly present and associated with gluten intake regardless of the histological pathology. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Duodenal epithelial cells need efficient defence strategies during gastric acidification of the lumen, while colonic mucosa counteracts damage by pathogens by building up a bacteria-free adherent mucus layer. Transport of HCO3(-) is considered crucial for duodenal defence against acid as well as for mucus release and expansion, but the transport pathways involved are incompletely understood. This study investigated the significance of the electroneutral Na(+)-HCO3(-) cotransporter NBCn1 for duodenal defence against acid and colonic mucus release. NBCn1 was localized to the basolateral membrane of duodenal villous enterocytes and of colonic crypt cells, with predominant expression in goblet cells. Duodenal villous enterocyte intracellular pH was studied before and during a luminal acid load by two-photon microscopy in exteriorized, vascularly perfused, indicator (SNARF-1 AM)-loaded duodenum of isoflurane-anaesthetized, systemic acid-base-controlled mice. Acid-induced HCO3(-) secretion was measured in vivo by single-pass perfusion and pH-stat titration. After a luminal acid load, NBCn1-deficient duodenocytes were unable to recover rapidly from intracellular acidification and could not respond adequately with protective HCO3(-) secretion. In the colon, build-up of the mucus layer was delayed, and a decreased thickness of the adherent mucus layer was observed, suggesting that basolateral HCO3(-) uptake is essential for optimal release of mucus. The electroneutral Na(+)-HCO3(-) cotransporter NBCn1 displays a differential cellular distribution in the murine intestine and is essential for HCO3(-)-dependent mucosal protective functions, such as recovery of intracellular pH and HCO3(-) secretion in the duodenum and secretion of mucus in the colon.

Objective: To investigate the relationship between the serum levels of IL-8, TNF-α, Gastrin and disease process in HP infection associated chronic gastritis and duodenal ulcer. Methods: Diagnosis was established in 35 HP positive chronic gastritis and 30 HP positive duodenal ulcer patients through gastroscopy, histopathology and 14 C-UBT test. RIA was adopted to measure the plasma contents of the three parameters in those 65 patients and 32 controls. Results: The serum IL-8, TNF-α and Gastrin (Gas) levels in patients with chronic gastritis were significantly higher than those in controls (p<0.01). Significant difference also existed between the contents in the two disease group (p<0.01). Conclusion: It proved that HP infection played an important role in the development of the two digestive tract diseases

The role of calcitriol in stimulating intestinal active Ca2+ absorption during postnatal life was studied in newborn, suckling, and weaned control (Con) piglets and piglets suffering from inherited calcitriol deficiency (Def piglets). In addition, a group of Def piglets was treated with vitamin D3 (Def-D3 piglets), which normalized plasma calcitriol levels. Regardless of age, duodenal calbindin-D9k concentrations ranged between 1,839 and 2,846 microg/g mucosa in Con piglets, between 821 and 1,219 microg/g mucosa in Def piglets, and between 2,960 and 3,692 microg/g mucosa in Def-D3 animals. In weaned animals, active Ca2+ absorption as calculated from in vitro 45Ca2+ flux rate measurements in Ussing chambers could be related to calbindin-D9k levels. Thus active Ca2+ absorption was completely absent in Def animals but was reconstituted in Def-D3 animals. In contrast, in newborn Def piglets active Ca2+ absorption functioned normally despite the low plasma calcitriol and mucosal calbindin-D9k levels and could not be affected by treatment with vitamin D3. Similar results were obtained from suckling Def piglets. The microtubule-disrupting agent colchicine caused significant inhibition of transepithelial net Ca2+ absorption in duodenal epithelia from newborn piglets without exerting an effect in suckling and weaned animals. Colchicine had no effect on Ca2+ uptake across the brush border membrane of mucosal enterocytes or on glucose-dependent electrogenic net ion flux rates in duodenal preparations from newborn Con piglets. In conclusion, our findings reveal intestinal active Ca2+ absorption during early postnatal life of pigs that involves calcitriol-independent mechanisms and that may include intact microtubule actions.

To evaluate the efficacy and safety of emergency endoscopic needle-knife precut papillotomy in acute severe cholangitis resulting from impacted common bile duct stones at duodenal papilla. Between January 2010 and January 2015, 118 cases of acute severe cholangitis with impacted common bile duct stones at the native papilla underwent emergency endoscopic retrograde cholangiopancreatography (ERCP) and early needle-knife precut papillotomy in a tertiary referral center. Precut techniques were performed according to the different locations of stones in the duodenal papilla. Clinical data about therapy and recovery of the 118 patients were recorded and analyzed. One hundred and eighteen patients underwent emergency ERCP within 24 h after hospitalization, with a total success rate of 100%. The mean operating time was 6.4 ± 4.1 min. Postoperative acute physiology and chronic health evaluation (APACHE) II scores, white blood cell count and liver function improved significantly. The complication rate was 4.2% (5/118); two with hemorrhage and three with acute pancreatitis. There was no procedure-related mortality. Emergency endoscopic needle-knife precut papillotomy is effective and safe for acute severe cholangitis resulting from impacted common bile duct stones at the duodenal papilla.

Helicobacter pylori (HP) infection can influence the inflammatory and immune responses in the gut and may therefore play a role in the development of gluten-related enteropathy in genetically susceptible individuals. Our objective was to assess the relationship between celiac disease and HP infection in children. Children (1-18 years) diagnosed as celiac disease (CD) (n = 324) with submission of gastric and duodenal biopsies and duodenal histology having Marsh grade III features were eligible for the study. Non-celiac patients referred for endoscopy were selected as controls. We studied proportion of HP prevalence in children with confirmed CD as compared with HP prevalence in reference group comprising non-celiac children referred for endoscopy. We also evaluated predictors of HP infection in children with celiac disease. Of the 324 participants with CD, gastric HP was seen in 37 (11.4%) patients. The prevalence of HP in patients without CD (50%, P Celiac disease and gastric HP infection have inverse relationship that raises the question whether development of HP infection confers protection against CD. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

2014-08-01

Celiac disease is a complex autoimmune disease affecting patients of any age, who may present a wide variety of clinical manifestations. Different guidelines for the diagnosis and management of celiac disease have been recently published. The aim of this study was to determine whether the recommendations issued in these guidelines have been adopted by physicians in France when celiac disease was suspected. A total of 5521 physicians were asked to fill in a detailed questionnaire on diagnosing celiac disease to evaluate their medical practice, as to the type of symptoms leading to the suspicion of celiac disease, the prescription of duodenal biopsy or serological tests, the type of serological tests (anti-tissue transglutaminase, anti-endomysium, anti-gliadin and anti-reticulin antibodies, total immunoglobulin A measurement) prescribed to diagnose celiac disease. The analysis of the responses of 256 general practitioners (GPs), 221 gastroenterologists and 227 pediatricians showed that the protean clinical presentations of celiac disease might be better recognized by gastroenterologists and pediatricians than by GPs. Gastroenterologists asked for duodenal biopsy much more often than GPs and pediatricians when celiac disease was suspected. Serological testing and knowledge of critical markers, prescribed to diagnose celiac disease, differed among GPs, gastroenterologists and pediatricians. Analysis of medical prescriptions showed that the recommendations for celiac disease diagnosis are not necessarily followed by physicians, emphasizing the fact that the impact of national or international guidelines on medical behavior should be evaluated. © 2014 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

Full Text Available Introduction: According to previous studies celiac disease(CD is frequently associated with chronic gastritis. The aim of this study was to assess the prevalence of CD and Helicobacter pylori in patients with dyspepsia. Methods: 325 patients were studied from April 2008 to April 2009 who underwent endoscopic procedures for dyspepsia. Gastric antrum, duodenal biopsies, serology with tissue Transglutaminase Antibodies(tTGA and total IgA were performed for detection of H. pylori and CD. Results: Out of 325 patients 312(96% had a positive H. pylori. Heart burn and bloating were the most prevalent symptoms in this study. Twenty one of 25 patients with positive histology for CD who had gastric biopsies were positive for H. pylori(84%. Duodenal biopsy specimens results have shown normal histology in 213(65.5%, hyperplastic polyps in 1(0.4%, duodenitis in 79(24.3% and abnormality in small bowel (Marsh I-IIIc in 25(10%. In term of the serological analysis, 9 of 26 tTGA positive patients had abnormal histology (Marsh I-IIIc(2.7%. Conclusion: Similar to previous reports, we found a high prevalence of H. pylori infection and celiac disease in dyspeptic patients. Therefore, further studies for screening occult CD in dyspeptic patients is seems necessary.

Acid suppression increases rates of Barrett's esophagus and esophageal injury in the presence of duodenal reflux.

LENUS (Irish Health Repository)

2012-01-31

BACKGROUND: The contribution of gastric acid to the toxicity of alkaline duodenal refluxate on the esophageal mucosa is unclear. This study compared the effect of duodenal refluxate when acid was present, decreased by proton pump inhibitors (PPI), or absent. METHODS: We randomized 136 Sprague-Dawley rats into 4 groups: group 1 (n = 33) were controls; group 2 (n = 34) underwent esophagoduodenostomy promoting "combined reflux"; group 3 (n = 34) underwent esophagoduodenostomy and PPI treatment to decrease acid reflux; and group 4, the \\'gastrectomy\\' group (n = 35) underwent esophagoduodenostomy and total gastrectomy to eliminate acid in the refluxate. Esophaguses were examined for inflammatory, Barrett\\'s, and other histologic changes, and expression of proliferative markers Ki-67, proliferating cell nuclear antigen (PCNA), and epidermal growth factor receptor (EGFR). RESULTS: In all reflux groups, the incidence of Barrett\\'s mucosa was greater when acid was suppressed (group C, 62%; group D, 71%) than when not suppressed (group B, 27%; P = 0.004 and P < .001). Erosions were more frequent in the PPI and gastrectomy groups than in the combined reflux group. Edema (wet weight) and ulceration was more frequent in the gastrectomy than in the combined reflux group. Acute inflammatory changes were infrequent in the PPI group (8%) compared with the combined reflux (94%) or gastrectomy (100%) groups, but chronic inflammation persisted in 100% of the PPI group. EGFR levels were greater in the PPI compared with the combined reflux group (P = .04). Ki-67, PCNA, and combined marker scores were greater in the gastrectomy compared with the combined reflux group (P = .006, P = .14, and P < .001). CONCLUSION: Gastric acid suppression in the presence of duodenal refluxate caused increased rates of inflammatory changes, intestinal metaplasia, and molecular proliferative activity. PPIs suppressed acute inflammatory changes only, whereas chronic inflammatory changes persisted.

Biphasic effect of duodenal ulcerogens cysteamine (C), mepirizole (M) and 1-methyl-4-phenyl-1,2,3,6-tetrahydropryridine (MPTP) on gastric emptying in the rat

The effect of acute or chronic administration of duodenal ulcerogens on gastric emptying (GE) of a liquid meal was investigated. In Sprague-Dawley rats (150-200g) 2 ml of /sup 51/Cr in 2% dextrose (5000 CPM) was given intragastrically and the GE half life was established as 7.6 min (controls). In acute experiments, C (30mg/100g), M (40mg/100g) or MPTP (4mg/100g) injected subcutaneously all delayed GE at 1, 2, 4, 8 and 24 hr by 15-77%. Maximal GE delay (p<0.05) by 77, 48 or 71% was found 1, 1 or 2 hr after C, M or MPTP, respectively. In chronic experiments, C (22mg/100g) was given x3 on the first day and once daily (25mg/100g) for 3 or 10 additional days. M (20mg/100g) once daily and MPTP (4mg/100g) x3 daily were given for 4 or 11 days. GE was measured on the 5th and 12th day. Chronically, MPTP accelerated GE by 63 and 31% at 5 and 12 days (p<0.05) and C and M did not change GE. The severity of duodenal ulcers correlated (p<0.05) with the amount of /sup 51/Cr remaining in the stomach: r=-0.68, -0.74 and -0.70 after C, M and MPTP, respectively. Acute administration of duodenal ulcerogens delay GE in rats. Chronic treatment with duodenal ulcerogens either accelerates or does not change GE. The most severe chronic ulcers exhibit the most rapid emptying. The authors data suggest that rapid GE might be a secondary rather than a primary alteration in duodenal ulceration.

Celiac disease shares features of other disorders. It can be diagnosed conclusively only based on duodenal histology analysis, which is not practical for screening purposes. Serologic analysis might be used to identify candidates for biopsy analysis. We aimed to develop a simple diagnostic approach that all clinicians could follow to increase the percentage of patients accurately diagnosed with celiac disease at initial presentation. We performed a retrospective analysis of data from 752 patients (88 with celiac disease, none were IgA deficient) who attended a UK district general hospital from January 2007 through December 2008 and underwent biopsy analysis and serologic tests to measure endomyseal antibodies and IgA antibodies against tissue transglutaminase (tTG). Patients avoiding gluten in their diet were excluded. Patients were assigned to 1 of 4 groups: high-risk (based on presence of anemia, chronic diarrhea, unintentional weight loss, or dermatitis herpetiformis), low-risk (based on such factors as dyspepsia, abnormal liver function, ataxia, or chronic cough), nutrient deficiency (based on levels of iron, vitamins B12 and D, or folate), or screening (because they had type 1 diabetes or a family history of celiac disease). Patients with celiac disease were identified using the modified Marsh criteria (grades 1-3) for interpreting duodenal histology. We compared clinical category, serology profiles, and biopsy results between patients with and without celiac disease. Celiac disease was diagnosed in 64 of 565 patients in the high-risk group (11%), 14 of 156 patients in the low-risk group (9%; P = .47 compared with high-risk group), 7 of 28 patients in the nutrient-deficiency group, and 3 of 3 patients in the screening group. Among 71 patients who tested positive for both antibodies (tTG and endomyseal antibodies), the positive predictive value for celiac disease was 97%; a negative test result for tTG had a negative predictive value of 98%. Among 708 patients

Full Text Available Duodenal metastasis from renal cell carcinoma is rare, and even rarer is a massive gastrointestinal bleeding from such tumours. Coeliac occlusive disease, although rarely symptomatic, can lead to ischaemic changes with anastomotic dehiscence and leaks when a patient undergoes pancreatoduodenectomy. A 41-year-old man with known metastasis to the adrenal glands and the second part of the duodenum close to the ampulla of Vater from clear cell renal cell carcinoma was admitted to our department due to massive gastrointestinal bleeding from the duodenal metastasis. Endoscopic control of the bleed was not possible, while the bleeding vessel embolization was able to control the haemorrhage only temporarily. An angiography during the embolization demonstrated the presence of stenosis of the coeliac artery and also hypertrophic inferior pancreaticoduodenal arteries supplying the proper hepatic artery via the gastroduodenal artery (GDA. The patient underwent emergency pancreatoduodenectomy with preservation of the gastroduodenal artery. The patient had an uneventful recovery and did not experience further bleeding. Also the blood flow to the liver was compromised as shown by the normal liver function tests (LFTs postoperatively. To the best of our knowledge, this is the first report of a preservation of the GDA during an emergency pancreatoduodenectomy.

Whipple\\'s procedure is the treatment of choice for pancreatic and periampullary malignancies. Preoperative histological confirmation of malignancy is frequently unavailable and some patients will subsequently be found to have benign disease. Here, we review our experience with Whipple\\'s procedure for patients ultimately proven to have benign disease. The medical records of all patients who underwent Whipple\\'s procedure during a 15-year period (1987-2002) were reviewed; 112 patients underwent the procedure for suspected malignancy. In eight cases, the final histology was benign (7.1%). One additional patient was known to have benign disease at resection. The mean age was 50 years (range: 30-75). The major presenting features included jaundice (five), pain (two), gastric outlet obstruction (one), and recurrent gastrointestinal haemorrhage (one). Investigations included ultrasound (eight), computerised tomography (eight), endoscopic retrograde cholangiopancreatography (seven; of these, four patients had a stent inserted and three patients had sampling for cytology), and endoscopic ultrasound (two). The pathological diagnosis included benign biliary stricture (two), chronic pancreatitis (two), choledochal cyst (one), inflammatory pseudotumour (one), cystic duodenal wall dysplasia (one), duodenal angiodysplasia (one), and granular cell neoplasm (one). There was no operative mortality. Morbidity included intra-abdominal collection (one), anastomotic leak (one), liver abscess (one), and myocardial infarction (one). All patients remain alive and well at mean follow-up of 41 months. Despite recent advances in diagnostic imaging, 8% of the patients undergoing Whipple\\'s procedure had benign disease. A range of unusual pathological entities can mimic malignancy. Accurate preoperative histological diagnosis may have allowed a less radical operation to be performed. Endoscopic ultrasound-guided fine needle aspirate (EUS-FNA) may reduce the need for Whipple\\'s operation

This national clinical guideline approved by the Danish Society for Gastroenterology and Hepatology describes the diagnosis and treatment of celiac disease (CD) in adults. CD is a chronic immunemediated enteropathy of the small intestine triggered by the ingestion of gluten-containing proteins......, which are found in wheat, rye, and barley. The disease prevalence is 0.5-1.0%, but CD remains under-diagnosed. The diagnosis relies on the demonstration of lymphocyte infiltration, crypt hyperplasia, and villous atrophy in duodenal biopsies. Serology, malabsorption, biochemical markers......, and identification of specific HLA haplotypes may contribute to CD diagnosis. Classical CD presents with diarrhoea and weight loss, but non-classical CD with vague or extraintestinal symptoms is common. The treatment for CD is a lifelong gluten-free diet (GFD), which, in the majority of patients, normalises...

Our objective was to determine duodenal and ileal flows of total and esterified fatty acids and to determine ruminal fermentation characteristics and site and extent of nutrient digestion in sheep fed an 80% concentrate diet supplemented with high-linoleate (77%) safflower oil at 0, 3, 6, and 9% of DM. Oil was infused intraruminally along with an isonitrogenous basal diet (fed at 2% of BW) that contained bromegrass hay, cracked corn, corn gluten meal, urea, and limestone. Four crossbred wethers (BW = 44.3 +/- 15.7 kg) fitted with ruminal, duodenal, and ileal cannulas were used in a 4 x 4 Latin square experiment, in which 14 d of dietary adaptation were followed by 4 d of duodenal, ileal, and ruminal sampling. Fatty acid intake increased (linear, P = 0.004 to 0.001) with increased dietary safflower oil. Digestibilities of OM, NDF, and N were not affected (P = 0.09 to 0.65) by increased dietary safflower oil. For total fatty acids (free plus esterified) and esterified fatty acids, duodenal flow of most fatty acids, including 18:2c-9,c-12, increased (P = 0.006 to 0.05) with increased dietary oil. Within each treatment, duodenal flow of total and esterified 18:2c-9,c-12 was similar (P = 0.32), indicating that duodenal flow of this fatty acid occurred because most of it remained esterified. Duodenal flow of esterified 18:1t-11 increased (P = 0.08) with increased dietary safflower oil, indicating that reesterification of ruminal fatty acids occurred. Apparent small intestinal disappearance of most fatty acids was not affected (P = 0.19 to 0.98) by increased dietary safflower oil, but increased (P = 0.05) for 18:2c-9,c-12, which ranged from 87.0 to 97.4%, and for 18:2c-9,t-11 (P = 0.03), which ranged from 37.9% with no added oil to 99.2% with supplemental oil. For esterified fatty acids, apparent small intestinal disappearance was from 80% for 18:3c-9,c-12,c-15 at the greatest level of dietary oil up to 100% for 18:1t-11 and 18:1c-12 with 0% oil. We concluded that

The association of dupA and Helicobacter pylori-related gastroduodenal diseases.

Science.gov (United States)

Hussein, N R

Helicobacter pylori is associated with the development of ulceration and gastric cancer. Recently, a novel virulence factor, duodenal ulcer promoting gene A (dupA), has been identified and found to associate with disease in some populations but not others. We investigated the relationship of dupA genotypes and H. pylori-related clinical outcomes by meta-analysis using previous reports of 2,358 patients from around the world. dupA-positive genotypes was found in 48% and was associated with duodenal ulcer (p = 0.001, odds ratio [OR] = 1.4, confidence interval [CI] = 1.1-1.7). The prevalence of dupA-positivity and its association with disease differed among the various regions around the world. In South America, the highest prevalence was recorded (Colombia and Brazil) and a significant relationship was found between dupA-negative strains and both gastric ulcer (GU) and gastric cancer (GC) (for GU, p = 0.001, OR = 0.2, CI = 0.1-0.4 and for GC, p = 0.001, OR = 0.3, CI = 0.2-0.6). In China, a significant correlation between dupA-positive strains and GU (p = 0.001, OR = 5.5, CI = 2.4-12.4) and GC (p = 0.009, OR = 2, Cl = 1.1-3.1) was found. To conclude, dupA promotes duodenal ulceration in some populations and GU and GC in others. This is typical of other virulence factors, such as cagA. Hence, it was concluded that the H. pylori virulence factor, dupA, is a true virulence factor.

Conclusion: When a patient is stable, even in the presence of delayed duodenal graft perforation, graft excision may not be necessary. Intraoperative exploration should include Doppler ultrasound examination of the vasculature to rule out thrombosis as a contributor to ischemia. Tissue biopsy should be performed to diagnose rejection.

Efficacy of Self-Expandable Metallic Stent Inserted for Refractory Hemorrhage of Duodenal Cancer

Directory of Open Access Journals (Sweden)

Takashi Orii

2016-05-01

Full Text Available Because of advances in the technology of gastrointestinal endoscopy and improvements in the quality of stents, it has become routine to place a stent as palliative therapy for malignant gastrointestinal obstruction. On the other hand, stent placement for malignant gastrointestinal hemorrhage has scarcely been reported, although it may be performed for hemorrhage of the esophageal varicose vein. We recently experienced a patient with refractory hemorrhage from an unresectable duodenal cancer who underwent placement of a self-expandable metallic stent (SEMS and thereafter had no recurrence of the hemorrhage. A 46-year-old man underwent laparotomy to radically resect a cancer in the third portion of the duodenum, which invaded widely to the superior mesenteric vein and its branches and was considered unresectable. After stomach-partitioning gastrojejunostomy was performed, chemotherapy was initiated according to the regimen of chemotherapy of far advanced gastric cancer. One year and 4 months after induction of chemotherapy, gastrointestinal hemorrhage occurred. Upper gastrointestinal endoscopy revealed the hemorrhage oozing from the duodenal cancer, and endoscopic hemostasis, such as injection of hypertonic saline epinephrine and argon plasma coagulation, was unsuccessful. Twenty days after emergence of the hemorrhage, an endoscopic covered SEMS was placed with confirmation by fluoroscopy. Immediately after placement of the stent, the tarry stool stopped and the anemia ceased to progress. The recurrence of the hemorrhage has not been confirmed without migration of the stent. SEMS is an effective hemostatic procedure for malignant refractory hemorrhage.

Celiac disease is a common non-communicable disease with varied presentations. Purpose of this study was to find the duodeno-endoscopic features in celiac disease and to compare duodeno-endoscopic and histological findings between typical and atypical celiac disease in children. Hospital based observational study was conducted at Sir Padampat Mother and Child Health Institute, Jaipur from June 2015 to May 2016. Patients were selected and divided in two groups- typical and atypical celiac disease based upon the presenting symptoms. Upper gastrointestinal endoscopy and duodenal biopsy was performed for serology positive patients. Results were analysed using appropriate statistical test of significance. Out of 101 enrolled patients, 47.5% were male. Age ranged from 1 to 18 years. Study showed that 54.5% were typical and 45.5% were atypical. Patients presenting with atypical symptoms were predominantly of older age group. On endoscopy, scalloping, mosaic pattern, reduced fold height and absent fold height; and in histology, advanced Marsh stage were significantly higher in the typical group. Awareness of atypical presentations as well as duodeno-endoscopic features may have considerable practical importance for the diagnosis of celiac disease in children. Scalloping, mosaic pattern, reduced fold height and nodularity are main endoscopic markers of celiac disease in children. Endoscopic markers of duodenal mucosa may be important in early diagnosis of celiac disease, in children subjected to endoscopy for atypical presentations or indication other than suspected celiac disease.

Objective: To determine eosinophil and mast cell populations in gastric and duodenal mucosal biopsies of adults with nonulcer dyspepsia (NUD) as compared to non-dyspeptic adults. Study Design: A case control study. Place and Duration of Study: Shahid Sadoughi University of Medical Sciences, Yazd, Iran, from January 2010 to June 2011. Methodology: A total of 52 (25 non-ulcer dyspeptic patients as case and 27 non-dyspeptic patients as control) patients underwent endoscopy. All patients had a minimum of 2 forceps biopsies obtained from stomach and duodenum. Routine histological evaluation was performed and additionally evaluated to determine eosinophil and mast cell counts. The statistical analysis was performed on SPSS version 17.0, using Mann-Whitney test with significance at p < 0.05. Results: The mean age in the case and control groups was 31.72 +- 12.17 and 35.74 +- 12.42 years respectively. The median eosinophil density in gastric mucosa in case group was 5.0 (ranging from 1 to 20) and 4.0 in control group (ranging from 0 to 16; p = 0.140). The median eosinophil density in duodenal mucosa in case group was 16.0 (ranging from 2 to 24) and 13 in control group (ranging from 2 to 45; p = 0.147). The median mast cell density in gastric mucosa in case group was 4.0 (ranging from 0 to 33) and 4.0 in control group (ranging from 0 to 26; p = 0.827). The median mast cell density in duodenal mucosa in case group was 4.0 (ranging from 0 to 31) and 3.0 in control group (ranging from 1 to 23; p = 0.704). The frequency of Helicobacter pylori infection in both the groups was similar. Conclusion: Although there were not statistically significant differences in eosinophil and mast cell densities between case and control groups, there was a trend toward mild eosinophilia in gastric and duodenal mucosa. The specific role of eosinophils and mast cells in NUD is yet to be completely defined. (author)

Leucine (Leu), one of the three branch chain amino acids, acts as a signaling molecule in the regulation of overall amino acid (AA) and protein metabolism. Leucine is also considered to be a potent stimulus for the secretion of insulin from pancreatice β-cells. Our objective was to study the effects of a duodenal bolus infusion of Leu on insulin and glucagon secretion, on plasma AA concentrations, and to do a metabolomic profiling of dairy cows as compared to infusions with either glucose or saline. Six duodenum-fistulated Holstein cows were studied in a replicated 3 × 3 Latin square design with 3 periods of 7 days, in which the treatments were applied at the end of each period. The treatments were duodenal bolus infusions of Leu (DIL; 0.15 g/kg body weight), glucose (DIG; at Leu equimolar dosage) or saline (SAL). On the day of infusion, the treatments were duodenally infused after 5 h of fasting. Blood samples were collected at -15, 0, 10, 20, 30, 40, 50, 60, 75, 90, 120, 180, 210, 240 and 300 min relative to the start of infusion. Blood plasma was assayed for concentrations of insulin, glucagon, glucose and AA. The metabolome was also characterized in selected plasma samples (i.e. from 0, 50, and 120 min relative to the infusion). Body weight, feed intake, milk yield and milk composition were recorded throughout the experiment. The Leu infusion resulted in significant increases of Leu in plasma reaching 20 and 15-fold greater values than that in DIG and SAL, respectively. The elevation of plasma Leu concentrations after the infusion led to a significant decrease (Pcows were reduced (Pinsulin were not affected by Leu. In DIG, insulin and glucose concentrations peaked at 30-40 and 40-50 min after the infusion, respectively. Insulin concentrations were greater (Pcows were compared with the DIG and SAL cows at 50 and 120 min after the infusion. By using this analysis, several metabolites, mainly acylcarnitines, methionine sulfoxide and components from the

The duodenal ulcer (DU)-promoting gene (dupA) of Helicobacter pylori has been identified as a novel virulent marker associated with an increased risk for DU. The presence or absence of dupA gene of H. pylori present in patients with DU and functional dyspepsia in North Indian population was studied by polymerase chain reaction (PCR) and hybridization analysis. One hundred and sixty-six patients (96 DU and 70 functional dyspepsia) were included in this study. In addition, sequence diversity of dupA gene of H. pylori found in these patients was analyzed by sequencing the PCR products jhp0917 and jhp0918 on both strands with appropriate primers. PCR and hybridization analyses indicated that dupA gene was present in 37.5% (36/96) of H. pylori strains isolated from DU patients and 22.86% (16/70) of functional dyspepsia patients (p dupA was significantly associated with the cagA-positive genotype (p dupA gene with DU in this population. The dupA gene can be considered as a novel virulent marker for DU in this population.

Studies describing the prevalence of upper gastrointestinal (GI) Crohn disease (CD) and its histopathologic changes have been inconsistent as a result of different definitions used for upper GI involvement, diverse populations, and varying indications for endoscopy. We reviewed the literature describing endoscopic findings and histologic lesions in gastric and duodenal mucosa of patients with established CD. PubMed, EMBASE, and the Cochrane Library were searched for gastroduodenal biopsy findings in patients with CD from 1970 to 2014. We included all retrospective and prospective studies in adults. We calculated the prevalence of the most common endoscopic and histopathological findings among patients with overall CD and upper GI CD. Of the 385 articles identified, 20 eligible studies were included. A total of 2511 patients had CD and 815 had upper GI CD. In the CD group, the most common histopathological finding was nonspecific gastric inflammation in 32% of patients, followed by gastric granuloma in 7.9%. Focal gastritis was prevalent in 30.9% of patients. In the upper GI CD group, gastric inflammation was present in 84% of patients, followed by duodenal inflammation in 28.2% and gastric granuloma in 23.2%. The most common gastric endoscopic finding in patients with CD was erythema in 5.9%, followed by erosions in 3.7%. Duodenal endoscopic findings included ulcers and erythema in 5.3% and 3.0% of patients, respectively. We found a prevalence of 34% for CD involving the upper GI tract across these 20 studies. Routine upper endoscopy with biopsies of the upper GI tract in the diagnostic workup of patients with CD can correctly classify the distribution and extent of the disease.

Celiac disease is a chronic autoimmune enteropathy caused by gluten ingestion. While its prevalence in Western countries is reported to be as high as 1%, the prevalence has not been evaluated in a large-scale study of a Japanese population. The aim of our study was to clarify the possible presence of celiac disease in a Japanese non-clinical population as well as in patients showing symptoms suggestive of the disease. Serum samples were collected from 2008 non-clinical adults and 47 patients with chronic unexplained abdominal symptoms between April 2014 and June 2016. The anti-tissue transglutaminase (TTG) immunoglobulin A antibody titer was determined as a screening test for celiac disease in all subjects, and individuals with a value of >2 U/mL subsequently underwent testing for the presence of serum endomysial IgA antibody (EMA) as confirmation. Those testing positive for EMA or with a high concentration (>10 U/mL) of TTG were further investigated by histopathological examinations of duodenal mucosal biopsy specimens and HLA typing tests. Of the 2008 non-clinical adults from whom serum samples were collected, 161 tested positive for TTG, and all tested negative for EMA. Four subjects who had a high TTG titer were invited to undergo confirmatory testing, and the histopathological results confirmed the presence of celiac disease in only a single case (0.05%). Of the 47 symptomatic patients, one (2.1%) was found to have a high TTG titer and was diagnosed with celiac disease based on duodenal histopathological findings. The presence of celiac disease in a non-clinical Japanese population was low at 0.05% and was rarely found in patients with unexplained chronic abdominal symptoms.

The purpose of this study was to determine whether oral immunization of ferret kits with a whole-cell sonicate of Helicobacter mustelae lysate (Hml) and the adjuvant muramyl dipeptide (MDP) would reduce the incidence of natural colonization with H. mustelae and the extent of Helicobacter-associated gastritis by enhancing the host mucosal immune response. Between the ages of 4 and 11 weeks, 44 ferret kits were gavaged with Hml and various doses of MDP. The extent of gastritis and duodenitis and the immune response to H. mustelae were evaluated. All kits became colonized naturally with H. mustelae and the majority developed mild to severe gastritis and duodenitis. Kits that received Hml with MDP developed significantly greater inflammation of the gastric antrum and duodenum, as compared to kits vaccinated with Hml alone. Vaccination with Hml and 50 micrograms of MDP was associated with severe lesions in the proximal duodenum characterized by accumulation of mononuclear inflammatory cells, mucosal erosion, and ulceration. Although serum antibody specific for H. mustelae in 4-week-old kits was approximately 50% of adult levels, a finding attributable to passively acquired maternal antibody, both systemic and mucosal antibody levels became depressed over time despite oral vaccination. The humoral immune response was sufficiently low to prevent detection of any significant dose effect of MDP on antibody levels among experimental groups. Oral vaccination of young ferrets with Hml and 50 micrograms MDP increased the risk of Helicobacter-associated mucosal ulceration in the proximal duodenum, which was associated with low humoral (but significant cell-mediated) immune responses to H. mustelae. In retrospect, the frequency of vaccination may have suppressed the systemic humoral immune response, thereby promoting mucosal damage by H. mustelae. The 50-microgram dose of MDP enhanced the cell-mediated immune response, which indirectly contributed to development of severe lesions

Full Text Available OBJETIVOS: Apresentar a experiência dos autores no tratamento do pâncreas anular, comparando os dados com os da literatura. MÉTODOS: É relatada a experiência do Departamento de Cirurgia Geral do Hospital de Clínicas de Porto Alegre em pâncreas anular com a descrição de quatro pacientes. A doença manifestou-se em três faixas etárias distintas: uma no período neonatal, outra na infância e duas na fase adulta. O quadro clínico de obstrução intestinal alta esteve presente em três dos quatro pacientes. Dor abdominal foi queixa constante entre os adultos. A investigação diagnóstica foi realizada através do estudo contrastado do estômago e duodeno, da endoscopia digestiva e da tomografia abdominal. A confirmação diagnóstica somente foi possível durante a laparotomia. A derivação duodenal foi a técnica cirúrgica empregada em dois casos e a ressecção do tecido pancreático nos pacientes adultos. RESULTADOS: Os quatros pacientes evoluíram favoravelmente no período pós-operatório. O tempo de internação hospitalar variou de 9 a 12 dias, com média de 10,5 dias. Não houve complicação cirúrgica e todos os pacientes permanecem assintomáticos em acompanhamento ambulatorial. CONCLUSÃO: A raridade desta anomalia não permite um estudo mais detalhado e comparativo. Os resultados aqui apresentados como os encontrados na literatura demonstram que a derivação duodenal e a ressecção pancreática são alternativas eficazes e seguras quando bem indicadas.PURPOSE: To present the authors experience managing anular pancreas and to compare the results found by the authors with the ones foundin the literature.

To report the histological features of celiac disease in a paediatric population originating from south Tunisia. A retrospective study of a series of duodenal biopsies from 114 children with celiac disease diagnosed over a period of 6 years (from January 1999 to December 2004). The diagnosis was confirmed by histological results, serological studies and clinical response to gluten free diet. The average age of patients was of 6.2 years (range 6 months-15 years). Sex ratio was 0.71. Symptoms were dominated by chronic diarrhea (48%), weight loss (50%) and anemia (20.1%). Histological findings showed an intraepithelial lymphocytosis (Marsh type 1) in 12.2% of cases, type 2 was present in 1.7% of cases and type 3 (villous atrophy) in 86% of cases. A treatment with a gluten-free diet was indicated for all patients, only the cases who haven't presented a clinical amelioration (11 cases) have beneficed a control biopsie; a villous atrophy was persistent in 80% of this patients. Histological features in duodenal biopsies for the diagnosis and the follow-up of patients with coeliac disease. This allows an appropriate treatment and prevents further complications.

Ruminant products are criticised for their SFA content relative to PUFA, although n-6:n-3 PUFA is desirable for human health ( content of rumen protozoa offers a potentially novel approach to enhance PUFA flow to the duodenum and subsequent incorporation into meat and milk. We evaluated protozoal contribution to duodenal n-3 PUFA flow due to intracellular chloroplast content. A total of six Holstein × Friesian steers were fed, in a two-period changeover design, either straw:concentrate (S:C, 60:40; DM basis; S:C, low chloroplast) or fresh perennial ryegrass (PRG; high chloroplast). Following 12 d adaptation to diet, ruminal protozoal and whole duodenal samples were obtained. N and fatty acid content of whole duodenum and rumen protozoal samples were assessed and protozoal 18S rDNA quantitative PCR performed, enabling calculation of protozoal N flow. The ratio of individual fatty acids:N in rumen protozoal samples was calculated to obtain protozoal fatty acid flows. Based on total fatty acid flow, contribution (%) of protozoa to individual fatty acid flows was calculated. Protozoal fatty acid data and microscopical observations revealed that protozoa were enriched with 18 : 3n-3 following PRG feeding, compared with the S:C diet, due to increased intracellular chloroplast content. However, duodenal protozoal 18S rDNA concentration post PRG feeding was low, indicating rumen retention of the protozoa. Nutrition influences the 18 : 3n-3 content of protozoa; the challenge is to increase protozoal flow to the small intestine, while maintaining sustainable rumen densities.

Plasma, duodenal, and rectal tissue antiretroviral therapy (ART) drug concentrations, human immunodeficiency virus (HIV) RNA and HIV DNA copy numbers, and recovery of mucosal immunity were measured before and 9 months after initiation of 3 different ART regimens in 26 subjects. Plasma and tissue HIV RNA correlated at baseline and when 9-month declines were compared, suggesting that these compartments are tightly associated. Antiretroviral tissue:blood penetration ratios were above the 50% inhibitory concentration values in almost 100% of cases. There were no correlations between drug concentrations and HIV DNA/RNA. Importantly, no evidence was found for residual viral replication or deficient tissue drug penetration to account for delayed gastrointestinal-associated lymphoid tissue immune recovery. © The Author 2017.

2012-01-01

Primer small intestine bezoar is seen rarely. It frequently arises from underlying small intestine pathologies (diverticle, tumor, stricture etc.). We report a very rare case of disopyrobezoar in the duodenal diverticulum, a kind of phytobezoar caused by persimmons, which was treated laparoscopically. The 47-year-old patient applied to polyclinic with complaints of epigastric tenderness, occasional distension, and acid regurgitation. In endoscopical examination, impacted bezoar was determined in the diverticulum in the duodenum. Because it is too hard, it was unable to remove endoscopically. On the abdominal tomography, a smooth-bounded non-homogeneous mass including gas and soft tissue areas in the 2nd portion of the duodenum was detected. A barium meal confirmed the presence of a 5cm diameter diverticulum on the lateral wall of the second portion of the duodenum. It also showed an intraluminalfilling defect as well as the mottled appearance of the bezoar. Learned from history of the patient, that the patient consumed over persimmon in childhood. Generally, duodenal diverticles are asymptomatic. Surgical treatment is rarely necessary because of complications such as bleeding, perforation, abdominal pain, bezoar formation. As well as using methods such as gastric lavage, enzymatic dissolution, endoscopical fragmentation in the treatment of phytobezoar, their chances of success are low because its structure is rigid. Usually, surgical intervention is required. For the treatments of bezoar cases located in the small intestine, laparoscopic surgical method is a safe and feasible method in selected cases.

Esophageal Dysmotility, Gastro-esophageal Reflux Disease, and Lung Transplantation: What Is the Evidence?

Science.gov (United States)

Wood, Richard K

2015-12-01

Lung transplantation is an effective and life-prolonging therapy for patients with advanced lung disease (ALD). However, long-term patient survival following lung transplantation is primarily limited by development of an inflammatory and fibrotic process involving the lung allograft known as bronchiolitis obliterans syndrome (BOS). Although the precise cause of BOS remains uncertain and is likely multifactorial, chronic aspiration of gastro-duodenal contents is one possible contributing factor. Multiple small, cross-sectional studies performed over the past two decades have reported a high prevalence of gastro-esophageal reflux disease (GERD) and esophageal dysmotility in the ALD population and several investigations suggest the prevalence may increase following lung transplantation. More recent studies evaluating the direct effect of gastro-duodenal contents on airways have demonstrated a possible biologic link between GERD and BOS. Despite the recent advances in our understanding of BOS, further investigations are needed to establish GERD as a causative factor in its development. This review will discuss the existing literature that has identified an association of GERD with ALD and post-transplant populations, with a focus on recent advances in the field.

Full Text Available Aims. To investigate the effect of biliary stent placement without endoscopic sphincterotomy (EST on common bile duct stones (CBDS disappearance and the contribution of preserving the duodenal papilla function to reduce recurrence of CBDS. Methods. Sixty-six patients admitted for acute obstructive cholangitis due to CBDS who underwent biliary stent placement without EST for 2 years from March 2011 were evaluated retrospectively. The second endoscopic retrograde cholangiopancreatography (ERCP was performed for treatment of CBDS 3 to 4 months after the first ERCP. We estimated the rate of stone disappearance at the time of second ERCP. Results. CBDS disappearance was observed in 32 (48.5% of 66 patients. The diameter of the bile ducts and the diameter of CBDS in patients with CBDS disappearance were significantly smaller than in those with CBDS requiring extraction (p=0.007 and p<0.001, resp.. Stone disappearance was evident when the diameter of bile ducts and that of CBDS were <10 and 7 mm, respectively (p=0.002. Conclusions. Short-term stent placement without EST eliminates CBDS while preserving duodenal papilla function and may be suitable for treating CBDS in patients with nondilated bile ducts and small CBDS.

Circulating antibodies to soya-derived protein antigens have been measured in patients with duodenitis, Crohn's disease, ulcerative colitis and coeliac disease. Significantly raised antibody titres were found frequently in the coeliac group, particularly those patients showing a suboptimal response to a gluten-free diet, but rarely in subjects with other gastrointestinal diseases. Antisoya activity was not necessarily accompanied by antibodies to other common dietary antigens. We suggest that some coeliacs may have an associated dietary soya sensitivity which could adversely influence their response to gluten withdrawal. PMID:7040491

Full Text Available 4-Dimethylaminoazobenzene (DAB, methyl yellow, or butter yellow, a human carcinogen, has been banned for use in foods since 1988. In 2014, DAB adulteration in Tofu occurred in Taiwan. We hypothesize that DAB can form [DAB•SBP]adduct adduct with soybean protein (SBP which could damage Gastro-Duodenal-Hepatic axis. Sprague-Dawley rats gavage fed [DAB•SBP]adduct adduct revealed severely reduced body weight and damaged duodenum, liver, hepatic mitochondria, and spleen. Hepatic levels of glutathione and ATP were severely reduced. Serum GOT and GPT were substantially elevated. Analysis by the adsorption isotherm clearly revealed DAB formed very stable [DAB•SBP]adduct adduct at 1:1 molar ration (Phase A. The equilibrium constant of this colloidal adduct [DAB•SBP]adduct was KeqA = ∝, behaving as the most stable and toxic species. At higher protein concentration (Phase C it formed conjugate [DAB×SBPgross]conjugate, with KeqC = 3.23×10-2 mg/mL, implicating a moderately strong adsorption. The in vitro pepsin digestibility test showed apparently reduced digestibility by 27% (by Ninhydrin assay or 8% (by Bradford assay. Conclusively, this is the first report indicating that [DAB•SBP]adduct potentially is capable to damage the Gastro-Duodenal-Hepatic axis.

The edible fruits of Pithecellobium dulce (Roxb.) Benth. are traditionally used for various gastric complications in India. Here, we investigated the antiulcer activity of hydroalcoholic fruit extract of P. dulce (HAEPD) by applying cysteamine induced duodenal ulcer model in rats. Duodenal ulcer was induced in male albino Wistar rats by oral administration of cysteamine @ 420 mg/kg body wt. as a single dose. The rats were pre-administered orally with HAEPD @ 200 mg/kg body wt. for 30 days prior to ulcer induction. Rats pre-administered with ranitidine @ 30 mg/kg body wt. served as reference drug control. Ulcer score, thiobarbituric acid reactive substances (TBARS), glycoproteins, superoxide dismutase, catalase and glutathione peroxidase and reduced glutathione levels were measured in the duodenum. Rats pre-administered with the HAEPD showed significantly reduced ulcer score comparable to that of ranitidine pretreated rats. The co-administration of HAEPD lowered the TBARS level and also restored the levels of glycoproteins, enzymatic and non-enzymatic antioxidants. Histopathological observations confirmed the presence of inflammation, necrosis and hemorrhagic spots in the duodenum of ulcer control rats which were significantly reduced due to HAEPD treatment. No abnormal alterations were observed in normal rats treated with HAEPD at the dosage studied. The results demonstrated antioxidant and cytoprotective nature of P. dulce, and thereby its significant anti ulcer property.

A lactose breath test (LBT) is usually used to diagnose lactase deficiency, and a lactose quick test (LQT) has been proposed as a new test on duodenal biopsies to detect this disorder. We aimed to assess the diagnostic accuracy of LBT and LQT and their ability to predict the clinical response to a lactose-free diet in patients with self-reported lactose intolerance. Fifty-five patients (age 47 ± 14 y; M/F 15/36) underwent upper gastrointestinal endoscopy and 25g-LBT. Two duodenal biopsies were taken to determine lactase deficiency (normal, mild, or severe) by LQT and to rule out other causes of secondary lactose malabsorption. Patients with a positive LBT and normal LQT also underwent a glucose breath test to exclude small intestinal bacterial overgrowth as a cause of the former result. The severity of gastrointestinal symptoms was measured with a GSS questionnaire, under basal condition and 1 month after a lactose-free diet. Lactose malabsorption was detected in 31/51 patients with LBT and in 37/51 patients with LQT (P = NS). Celiac disease was found in 2 patients. Two LBT+ patients showed a positive glucose breath test for small intestinal bacterial overgrowth. Eight patients had a mild hypolactasia by LQT and a negative LBT, but they had a significant improvement of symptoms after diet. LQT and LBT were concordant in 83% of cases and predicted the response to a lactose-free diet in 98% and 81% of the cases, respectively (P = 0.03). LQT is as sensitive as LBT in detecting lactase deficiency; however, it seems to be more accurate than LBT in predicting the clinical response to a lactose-free diet.

Aim. Atypical presentations of celiac disease (CD) have now been shown to be much more common than classical (typical) form. We evaluated the frequency of CD among adult patients with typical or atypical symptoms of CD. Materials and Methods. Patients referred to two outpatient gastroenterology clinics in Isfahan (IRAN) were categorized into those with typical or atypical symptoms of CD. IgA antitissue transglutaminase antibody was assessed and followed by duodenal biopsy. In patients for whom endoscopy was indicated (independent of the serology), duodenal biopsy was taken. Histopathological changes were assessed according to the Marsh classification. Results. During the study period, 151 and 173 patients with typical and atypical symptoms were evaluated (mean age = 32.8 ± 12.6 and 35.8 ± 14.8 years, 47.0% and 56.0% female, resp.). Frequency of CD in patients with typical and atypical symptoms was calculated, respectively, as 5.9% (9/151) and 1.25% (3/173) based on positive serology and pathology. The overall frequency was estimated as at least 9.2% (14/151) and 4.0% (7/173) when data of seronegative patients were also considered. Conclusions. CD is more frequent among patients with typical symptoms of malabsorption and these patients should undergo duodenal biopsy, irrespective of the serology. In patients with atypical symptoms, serological tests should be performed followed by endoscopic biopsy, and routine duodenal biopsy is recommended when endoscopic evaluation is indicated because of symptoms.

Full Text Available Fibronectin (FN, a large family of plasma and extracellular matrix glycoproteins, plays an important role in wound healing. PURPOSE: To evaluate the effect of fibronectin on the healing of sutured duodenal wounds, correlating with the serum and tissue level of the substance. METHODS: An experimental study was done in 30 adult Wistar rats divided into two group. In the control group (n=15 a duodenal suture was treated with saline solution 0,9% and in the test group the duodenal wounds were treated with 1% FN. The duodenal wound healing process was studied in the 5th, 7tn and 10th postoperative days, by histological sections stained by hematoxylin-eosin, Masson trichromic and immunohistochemical reaction for FN. A digital histological grading system was used to obtain a score for each group and to observe the healing process. RESULTS: the FN was present in the several layers of the duodenum and the cellular and plasmatic FN increased with the evolution of healing. In the test group the FN enhanced the wound healing within 5, 7 and 10 days after injury, when compared with the control group. CONCLUSION: The topical use of FN in duodenal sutured wounds in rats enhances healing by stimulating the appearence of fibroblasts into the wound site and development of granulation tissue. This acceleration of the repair process may have an important application in the healing of duodenal wounds.A fibronectina (FN, um componente da grande família das glicoproteínas do plasma e da matriz extracelular, desempenha um importante papel na cicatrização das feridas.

Endoscopic and interventional techniques are currently the mainstay of management of bleeding duodenal ulcer. As well, for patients with perforated duodenal ulcer, laparoscopic simple closure is nowadays usually performed. Although indications for emergency antroduodenectomy have declined, this procedure is still necessary as a salvage option when conservative management has failed or is not practicable. Our study aimed to evaluate indications and results of antroduodenectomy with gastroduodenal anastomosis in current practice and to examine the factors that predict operative outcomes. All patients who underwent emergency antroduodenectomy with gastroduodenal anastomosis in two surgical care departments specialized in emergency digestive surgery were studied from 2000 to 2015. Thirty-five patients (27 males, 77 %) with a median age of 68 years (20-90) underwent emergency antroduodenectomy with gastroduodenal anastomosis. Indications were bleeding and perforated duodenal ulcer in 24 and 11 patients, respectively. The overall complication rate was 69 %, especially because of a high rate of medical complications (57 %). Only two patients (6 %) required reoperation for anastomotic leakage. The overall mortality rate was 40 % (n = 14). According to the univariate analysis, age >70, >3 comorbidities, ASA score >2, and postoperative medical complications were associated with an increased risk of in-hospital mortality. In the multivariate analysis, age and ASA score remained independent risk factors. No recurrence of complicated duodenal disease was observed. Antroduodenectomy with gastroduodenal anastomosis is a safe and effective long-term strategy, with a low and acceptable rate of surgical complications, for complicated duodenal ulcer not responding to conservative measures.

Full Text Available O6-methylguanine-DNA methyltransferase (MGMT methylation status has not been extensively investigated in duodenal adenocarcinoma (DA. The aim of this study was to evaluate the MGMT methylation status and examine its possible prognostic value in patients with stage III DA.Demographics, tumor characteristics and survival were available for 64 patients with stage III DA. MGMT methylation was detected by using MethyLight. A Cox proportional hazard model was built to predict survival, adjusted for clinicopathological characteristics and tumor molecular features, including the CpG island methylator phenotype (CIMP, microsatellite instability (MSI, and KRAS mutations.MGMT methylation was detected in 17 of 64 (26.6% patients, and was not correlated with sex, age, tumor differentiation, CIMP, MSI, or KRAS mutations. MGMT methylation was the only one factor associated with both overall survival (OS and disease-free survival (DFS on both univariate and multivariate analyses. In patients treated with surgery alone, MGMT-methylated group had worse OS and DFS when compared with MGMT-unmethylated group. However, in patients treated with chemotherapy/radiotherapy, outcomes became comparable between the two groups.Our results demonstrate MGMT methylation is a reliable and independent prognostic factor in DAs. Methylation of MGMT is associated with poor prognosis in patients with stage III DAs.

Rat duodenal motility in vitro: Prokinetic effects of DL-homocysteine thiolactone and modulation of nitric oxide mediated inhibition

Full Text Available Homocysteine is a significant but modifiable risk factor for vascular diseases. As gastrointestinal smooth musculature is similar to blood vessel muscles, we investigated how elevated homocysteine levels affect nitric oxide-mediated neurotransmission in the gut. There is accumulated evidence that a dysfunction of NO neurons in the myenteric plexus may cause various diseases in the gastrointestinal tract such as achalasia, diabetic gastroparesis and infantile hypertrophic pyloric stenosis. In the present study, we aimed to assess the effects of homocysteine on NO-mediated responses in vitro, and to examine the effects of DL-homocysteine thiolactone on the spontaneous motility of rat duodenum and nitrergic neurotransmission. DL-homocysteine thiolactone concentration of 10 μmol/L leads to the immediate increase in tone, amplitude and frequency of spontaneous movements in isolated rat duodenum. L-NAME (30 μmol/L leads to an increase in basal tone, amplitude and frequency of spontaneous contractions. The relaxations induced by EFS were significantly reduced in duodenal segments incubated in DL-homocysteine thiolactone compared with the control group. EFS-induced relaxations were inhibited by L-NAME in both experimental and control groups. These results suggest that a high level of homocysteine causes an important impairment of non-adrenergic non-cholinergic innervation of the rat duodenum.

Although it is well known that celiac disease (CD) is associated with neurologic disorders, association with psychiatric problems is not well defined. In this report, we aimed to detect CD prevalence in patients with attention-deficit hyperactivity disorder (ADHD). A total of 362 patients between the ages 5 and 15 years with the diagnosis of ADHD according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) diagnostic criteria and 390 sex- and age-matched healthy children were included in the present study. Serum levels of tissue transglutaminase (tTg) immunoglobulin (Ig) A and IgG were studied in both groups. Serum IgA levels were also studied in patients with positive tTG IgG for the exclusion of selective IgA deficiency. Endoscopic duodenal biopsy was provided in seropositive patients, whose parents approved the procedure. Biopsy samples were evaluated according to Marsh-Oberhuber classification. tTg IgA was positive in 4 patients with ADHD (1.1%). Endoscopic duodenal biopsy was suggestive of CD in one of them (0.27%). tTg IgA was positive in 3 of control group patients (0.8%). Duodenal biopsy of the only patient from control group, who underwent upper gastrointestinal endoscopy, revealed normal intestinal mucosa. The seropositivity rates for CD were found similar in ADHD and control groups. Thus, neither routine screening for CD nor empirical recommendation of gluten-free diet seems necessary in children with ADHD.

Purpose: To quantify the effect of abdominal compression on duodenal motion during pancreatic radiotherapy. Methods: Seven patients treated for pancreatic cancer were selected for analysis. Four patients were treated with abdominal compression and three without. The duodenum was contoured by the same physician on each CBCT (five CBCTs for patients with compression, four for non-compression patients). CBCTs were rigidly registered using a soft tissue match and contours were copied to the delivered plans which were all radical (BED > 50 Gy). The distance between the duodenum on the planning CT and each CBCT was quantified by calculating the root mean square (RMS) distance. The DVHs of each abdominal compression patient was converted to an EQD2 DVH (alpha/beta = 10) using an in-house tool and volumes receiving at least 25, 35, 45, and 50 Gy were recorded. Results: The maximum variation in duodenal volumes on the CBCTs for the four abdominal compression patients were 19.1 cm 3 (32.8%), 19.1 cm 3 (20.6%), 19.9 cm 3 (14.3%), and 12.9 cm 3 (27.3%) compared to 15.2 cm 3 (17.6%), 34.7 cm 3 (83.4%), and 56 cm 3 (60.2%) for non-compression patients. The average RMS distance between the duodenum on the planning CT and each CBCT for all abdominal compression patients was 0.3 cm compared to 0.7 cm for non-compressed patients. The largest (and average) difference between the planning CT and CBCTs in volume of duodenum receiving more than 25, 35, 45 and 50 Gy for abdominal compression patients was 11% (5%), 9% (3%), 9% (2%), and 6% (1%). Conclusion: Abdominal compression reduces variation in volume and absolute position of the duodenum throughout treatment. This is seen as an improvement but does not eliminate the need to consider dosimetric effects of motion. Abdominal compression is particularly useful in SBRT when only a few fractions are delivered.

INTRODUCTION Primer small intestine bezoar is seen rarely. It frequently arises from underlying small intestine pathologies (diverticle, tumor, stricture etc.). We report a very rare case of disopyrobezoar in the duodenal diverticulum, a kind of phytobezoar caused by persimmons, which was treated laparoscopically. PRESENTATION OF CASE The 47-year-old patient applied to polyclinic with complaints of epigastric tenderness, occasional distension, and acid regurgitation. In endoscopical examination, impacted bezoar was determined in the diverticulum in the duodenum. Because it is too hard, it was unable to remove endoscopically. On the abdominal tomography, a smooth-bounded non-homogeneous mass including gas and soft tissue areas in the 2nd portion of the duodenum was detected. A barium meal confirmed the presence of a 5 cm diameter diverticulum on the lateral wall of the second portion of the duodenum. It also showed an intraluminalfilling defect as well as the mottled appearance of the bezoar. Learned from history of the patient, that the patient consumed over persimmon in childhood. DISCUSSION Generally, duodenal diverticles are asymptomatic. Surgical treatment is rarely necessary because of complications such as bleeding, perforation, abdominal pain, bezoar formation. As well as using methods such as gastric lavage, enzymatic dissolution, endoscopical fragmentation in the treatment of phytobezoar, their chances of success are low because its structure is rigid. Usually, surgical intervention is required. CONCLUSION For the treatments of bezoar cases located in the small intestine, laparoscopic surgical method is a safe and feasible method in selected cases.

The association between celiac disease and eating disorders has been very rarely reported. This is the first report on celiac disease associated with bulimia in this part of Europe. An adult female patient with history of bulimia and one uncomplicated pregnancy was admitted to the Gastroenterology Department, due to long lasting dyspeptic symptoms, constipation, major weight loss and fatigue. After positive serological screening, the diagnosis of celiac disease was confirmed with histopathology examination of duodenal biopsy specimen. Complicated interactions between celiac disease and bulimia can make them difficult to diagnose and treat. It is important to consider the presence of celiac disease in patients with bulimia and gastrointestinal symptoms.

In patients with Helicobacter pylori-positive duodenal ulcer (DU), the organism must be eradicated to achieve rapid, stable healing. However, evidence is against much else that is commonly accepted. (1) Does H. pylori cause the ulcer? Evidence against includes archaeopathology, geographical prevalence, temporal relationships and H. pylori-negative DU patients. DU can recur after eradication of H. pylori infection, and DUs may remain healed after reduction of acid secretion despite persistent infection. The faster healing of ulcers when H. pylori has been eradicated is due to the organism's interference with neoangiogenesis and the healing of wounded epithelial cells. (2) Does H. pylori infection persist until pharmacologically eradicated? Studies based on current infection show that H. pylori infection is a labile state that can change in 3 months. High rates of gastric acid secretion result in spontaneous cure, whereas low rates permit re-infection. Hydrochloric acid, necessary for producing a DU, is strongly associated with the likelihood of an ulcer. At the start, patients owe their ulcer to gastric hypersecretion of hydrochloric acid; approximately 60% may be H. pylori-negative. If acid is suppressed, the less acid milieu encourages invasion by H. pylori, especially if the strain is virulent.

Full Text Available Objective. Duodenal atresia (DA routinely has been corrected by laparotomy and duodenoduodenostomy with excellent long-term results. We revisited the patients with DA treated in the last 12 years (2004–2016 comparing the open and the minimally invasive surgical (MIS approach. Methods. We divided our cohort of patients into two groups. Group 1 included 10 patients with CDO (2004–09 treated with open procedure: 5, DA; 3, duodenal web; 2, extrinsic obstruction. Three presented with Down’s syndrome while 3 presented with concomitant malformations. Group 2 included 8 patients (2009–16: 1, web; 5, DA; 2, extrinsic obstruction. Seven were treated by MIS; 1 was treated by Endoscopy. Three presented with Down’s syndrome; 3 presented with concomitant malformations. Results. Average operating time was 120 minutes in Group 1 and 190 minutes in Group 2. In MIS Group the visualization was excellent. We recorded no intraoperative complications, conversions, or anastomotic leakage. Feedings started on 3–7 postoperative days. Follow-up showed no evidence of stricture or obstruction. In Group 1 feedings started within 10–22 days and we have 1 postoperative obstruction. Conclusions. Laparoscopic repair of DA is one of the most challenging procedures among pediatric laparoscopic procedures. These patients had a shorter length of hospitalization and more rapid advancement to full feeding compared to patients undergoing the open approach. Laparoscopic repair of DA could be the preferred technique, safe, and efficacious, in the hands of experienced surgeons.

A novel virulence factor, duodenal ulcer-promoting gene A (dupA), in Helicobacter pylori has been found to be associated with disease in certain populations but not in others. This study analysed a South-east Indian population as part of the debate about the relevance of dupA for the prediction of clinical outcomes. A total of 140 H. pylori strains isolated from duodenal ulcer (DU) (n = 83) and non-ulcer dyspepsia (NUD) patients (n = 57) were screened by PCR and dot-blot hybridization to determine the presence of the ORFs jhp0917 and jhp0918. Part of jhp0917-jhp0918 was sequenced to search for the C/T insertion that characterizes dupA and the levels of dupA transcripts were also assessed. The PCR and dot-blot results indicated the presence of jhp0917 and jhp0918 in 37.3 % (31/83) and 12.2 % (7/57) of H. pylori strains isolated from DU and NUD patients, respectively. Sequencing analysis showed insertion of a C at nt 1386 in the 3' region of jhp0917, forming the dupA gene in 35 strains. RT-PCR analysis detected the dupA transcript in 28 of these 35 strains. The expression level of the dupA transcript varied from strain to strain, as shown by real-time PCR. The results demonstrated that analysis based on PCR only for dupA may produce an erroneous interpretation. The prevalence of dupA was significantly greater among strains isolated from patients with DU than from patients with NUD in this population (P = 0.001, odds ratio = 4.26, confidence interval = 1.60-11.74). Based on these findings, dupA can be considered a biomarker for DU patients in India. The reported discrepancies for this putative virulence marker in different populations may be due to the genome plasticity of H. pylori.

More than 50% of the world population is infected with Helicobacter pylori (H. pylori). The bacterium highly links to peptic ulcer diseases and duodenal ulcer, which was classified as a group I carcinogen in 1994 by the WHO. The pathogenesis of H. pylori is contributed by its virulence factors including urease, flagella, vacuolating cytotoxin A (VacA), cytotoxin-associated gene antigen (Cag A), and others. Of those virulence factors, VacA and CagA play the key roles. Infection with H. pylori ...

Abstract A dog developed icterus, vomiting, and anorexia 2 wk after orthopedic surgery and treatment with meloxicam for approximately 1 y. Exploratory laparotomy revealed a single perforated duodenal ulcer. The most likely cause of the hyperbilirubinemia was intrahepatic cholestasis resulting from peritonitis associated with the perforation. PMID:15283521

Effective medical management of peptic ulcer disease (PUD) has reduced the incidence of gastric outlet obstruction (GOO) as a complication, but perforation especially in the elderly remains unchanged and is in fact on the increase. There is a changing trend in emergency surgery for perforated duodenal ulcer (PDU) from definitive anti ulcer surgery to simple closure followed by Helicobacter pylori eradication. To present our experience in managing PDU with simple closure followed by Helicobacter pylori eradication. This was a chart review of patients managed for PDU over a nine year period (Jan 1999 to Dec 2007) using information obtained from ward admission registers, theatre operation registers, and patients case files from the medical records department. The patients biodata, clinical, and operative findings as well as treatment outcome were extracted for analysis. Of 55 patients eligible for analysis, 44 (80%) were males and 11(20%) females (M to F, 4:1). Their ages ranged between 18 and 65 years with a mean(SD) of 39.9 (13.5) years. Most of the patients, 34 (61.8%), were below 40 years of age and majority 39(71.0%) had a history suggestive of chronic peptic ulcer disease. Twenty six (47.3%) patients presented within 24 hours of perforation, while nine (16.4%) presented more than 72 hours afterwards. The latter group accounted for most, five(55.6%), of the mortality. All the perforations were anterior pyloroduodenal and all except one had simple closure with omental patch followed by a course of a proton pump inhibitor and Helicobacter pylori eradication therapy. Simple closure with omental patch followed by Helicobacter pylori eradication is effective in managing PDU with low morbidity and mortality despite patients late presentation in our center. This technique is recommended in place of a definitive ulcer surgery.

Sixty-five patients with possible pancreatic disease or long-standing upper abdominal symptoms were examined by means of the secretin-CCK test and hypotonic duodenography. Both examinations were performed after one duodenal intubation. In patients with pancreatitis functional abnomalities were revealed in 85 per cent while the duodenography was abnormal in 43 per cent. In patients with carcinoma, 77 per cent had abnormal exocrine pancreas function and 70 per cent had abnormalities demonstrated at duodenography. The value of the two examinations for assessment of patients with upper abdominal symptoms and pancreatic disease is discussed. (Auth.)

To compare the outcome between laparoscopic gastrojejunostomy (LapGJ) and duodenal stenting (DS) in terms of oral intake, nutritional status, patency duration, effect on chemotherapy and survival. Medical records of 115 patients, who had LapGJ or duodenal stent placement between July 2005 and September 2015 in Seoul National University Bundang Hospital, have been reviewed retrospectively. Oral intake was measured with Gastric Outlet Obstruction Scoring System. Serum albumin and body weight was measured as indicators of nutritional status. The duration of patency was measured until the date of reintervention. Chemotherapy effect was calculated after the procedures. Survival period and oral intake was analyzed by propensity score matching age, sex, T-stage, comorbidities, and chemotherapy status. Forty-three LapGJ patients and 58 DS patients were enrolled. Improvement in oral intake was shown in LapGJ group versus DS group (88% vs. 59%, P = 0.011). Serum albumin showed slight but significant increase after LapGJ (+0.75 mg/dL vs. -0.15 mg/dL, P = 0.002); however, there was no difference in their body weight (+5.1 kg vs. -1.0 kg, P = 0.670). Patients tolerated chemotherapy longer without dosage reduction after LapGJ (243 days vs . 74 days, P = 0.006) and maintained the entire chemotherapy regimen after the procedure longer in LapGJ group (247 days vs. 137 days, P = 0.042). LapGJ showed significantly longer survival than DS (220 vs. 114 days, P = 0.004). DS can provide faster symptom relief but LapGJ can provide improved oral intake, better compliance to chemotherapy, and longer survival. Therefore, LapGJ should be the first choice in gastric outlet obstruction patients for long-term and better quality of life.

Handlebar Hernia With Jejunal and Duodenal Injuries: A Case Report

2004-09-01

Full Text Available Traumatic abdominal wall hernia is an uncommon complication of abdominal blunt trauma. Handlebar hernia is even more infrequent. To the best of our knowledge, there are fewer than 30 cases of handlebar hernia reported in the English literature. Associated intra-abdominal injuries are infrequent. We present a case of handlebar hernia with jejunal and duodenal injuries. Emergency surgical intervention included primary repair of the disrupted musculofascial defect and injuries of the duodenum and jejunum. Bile- stained discharge from the drain tube was noted, so a second operation was performed about 7 days after the first. Leakage from the sutured jejunal perforation and another irregular perforation in the posterior wall of the fourth portion of the duodenum were noted. The two perforations were debrided and repaired. The muscular and fascial defects were debrided and closed with interrupted sutures. The patient recovered smoothly and was discharged 30 days after the blunt injury. No other major complication was noted 11 months after surgery.

Infection by the Human T- Lymphotropic virus I (HTLV-1) causes Adult T cell Leukemia-lymphoma (ATLL), being the duodenal involvement rare. Commonly, patients co-infected with HTLV-1 and Strongyloides stercoralis are seen due to the lack of TH2 response found on these patients. We describe a 48-year- old woman, from the jungle of Peru, with a family history of HTLV-1 infection, who presented with a History of chronic diarrhea and weight loss. HTLV-1 infection with ATLL and strongyloidiasis were diagnosed. Ivermectin treatment and chemotherapy were initiated, being stabilized, and discharged. We report this case because of the unusual coexistence in the duodenum of ATLL and strongyloidiasis.

Chocolate consumption is associated with a decreased risk for CVD. Theobromine, a compound in cocoa, may explain these effects as it favorably affected fasting serum lipids. However, long-term effects of theobromine on postprandial metabolism as well as underlying mechanisms have never been studied. The objective was to evaluate the effects of 4-week theobromine consumption (500 mg/day) on fasting and postprandial lipid, lipoprotein and glucose metabolism, and duodenal gene expression. In a randomized, double-blind crossover study, 44 healthy men and women, with low baseline HDL-C concentrations consumed 500 mg theobromine or placebo daily. After 4-weeks, fasting blood was sampled and subjects participated in a 4-h postprandial test. Blood was sampled frequently for analysis of lipid and glucose metabolism. In a subgroup of 10 men, 5 h after meal consumption duodenal biopsies were taken for microarray analysis. 4-weeks theobromine consumption lowered fasting LDL-C (-0.21 mmol/L; P = 0.006), and apoB100 (-0.04 g/L; P = 0.022), tended to increase HDL-C (0.03 mmol/L; P = 0.088) and increased hsCRP (1.2 mg/L; P = 0.017) concentrations. Fasting apoA-I, TAG, FFA, glucose and insulin concentrations were unchanged. In the postprandial phase, theobromine consumption increased glucose (P = 0.026), insulin (P = 0.011) and FFA (P = 0.003) concentrations, while lipids and (apo)lipoproteins were unchanged. In duodenal biopsies, microarray analysis showed no consistent changes in expression of genes, pathways or gene sets related to lipid, cholesterol or glucose metabolism. It is not likely that the potential beneficial effects of cocoa on CVD can be ascribed to theobromine. Although theobromine lowers serum LDL-C concentrations, it did not change fasting HDL-C, apoA-I, or postprandial lipid concentrations and duodenal gene expression, and unfavorably affected postprandial glucose and insulin responses. This trial was registered on clinicaltrials.gov under

Peptic ulcer results from the prevalence of agents causing endoluminal lesions over the defence mechanisms of the mucosa of the upper GI tract. Particularly, in the case of duodenal ulcer, the pathogenetic relevance of non-buffered acid secretion of the early nighttime period has been emphasized. This is indeed confirmed by the fact that a single night dose of 800 mg cimetidine has apparently been proved able--in numerous controlled clinical trials--to provide results that are similar to those obtained with the classic dose of 1 g daily or 400 mg twice daily. Our centre carried out a crossover double-blind controlled trial aimed at evaluating titrable acidity and pH during the 24-h period in seven patients with active duodenal ulcer. The single nighttime dose of cimetidine resulted in a significant and long-lasting inhibition of acid secretion during the entire night. During the day, secretory values returned to levels similar to those obtained with placebo, hence allowing normal digestive functions.

A 24-week interventional prospective trial was performed to compare the benefits of open duodenal-jejunal exclusion surgery (GJB) with a matched control group on standard medical care. One-hundred eighty patients were screened for the surgical approach. Twelve patients accepted to be operated and presented the full eligibility criteria for surgery that includes overweight BMI (25-29.9 kg/m2), T2DM diagnosis for less than 15 years, insulin-treated patients, no history of major complications, preserved beta-cell function, and absence of autoimmunity. A matched control group (CG) of patients whom refused surgical treatment was placed to receive standard care. Patients had age of 50 (5) years, time of diagnosis 9 years (range, 3 to 15 years), time of insulin usage 6 months (range, 3 to 48 months), fasting glucose (FG), 9.8 (2.5) mg/dL, and glycated hemoglobin (A1C) 8.90 (2.12)%. At 24 weeks after surgery, patients experienced greater reductions on FG (14% vs. 7% on CG), A1C (from 8.78 to 7.84 in GJB-p<0.01 and 8.93 to 8.71 in CG; p<0.05 between groups) and reductions on average daily insulin requirement (93% vs. 29%, p<0.01). Ten patients stopped insulin usage in GJB but they remain taking oral medications.
