    A diverticulum is a bulging sack in any portion of the gastrointestinal tract. The most common site for the formation of diverticula is the large intestine. Small intestine diverticular disease is much less common than colonic diverticular disease. The most common symptom is non-specific epigastric pain and a bloating sensation. Major complications include diverticulitis, gastrointestinal bleeding, acute perforation, pancreatic or biliary (in the case of duodenal diverticula) disease, intesti...

    A diverticulum is a bulging sack in any portion of the gastrointestinal tract. The most common site for the formation of diverticula is the large intestine. Small intestine diverticular disease is much less common than colonic diverticular disease. The most common symptom is non-specific epigastric pain and a bloating sensation. Major complications include diverticulitis, gastrointestinal bleeding, acute perforation, pancreatic or biliary (in the case of duodenal diverticula) disease, intestinal obstruction, intestinal perforation, localized abscess, malabsorption, anemia, volvulus and bacterial overgrowth. We describe the clinical case of a 65-year-old female patient with a diagnosis on hospital admittance of acute appendicitis and a intraoperative finding of diverticular disease of the small intestine, accompanied by complications such as intestinal perforation, bleeding and abdominal sepsis. This was surgically treated with intestinal resection and ileostomy and a subsequent re-intervention comprising perforation of the ileostomy and stomal remodeling. The patient remained hospitalized for approximately 1 month with antibiotics and local surgical wound healing, as well as changes in her diet with food supplements and metabolic control. She showed a favorable clinical evolution and was dismissed from the hospital to her home. We include here a discussion on trends in medical and surgical aspects as well as early handling or appropriate management to reduce the risk of fatal complications. PMID:23185148

    Radionuclide Meckel`s diverticular studies are commonly requested to help distinguish the source of chronic gastrointestinal blood loss. However, several aetiologies may contribute to false-positive scan findings, for example inflammatory pathologies such as Crohn`s disease, ulcerative colitis, regional enteritis and intussusception, all of which commonly localise pertechnetate. In this paper, two cases of incidental findings on Meckel`s diverticular studies and their impact on patient management will be presented 4 refs., 2 figs.

    Full Text Available SUMMARY Small intestinal neoplasms are uncommonly encountered in clinical practice. Small intestinal neoplasms may occur sporadically, or in association with genetic diseases such as familial adenomatous polyposis coli or Peutz-Jeghers syndrome, or in association with chronic intestinal inflammatory disorders such as Crohn?s disease or celiac sprue. Benign small intestinal tumors such as leiomyoma, lipoma, hamartoma or desmoid tumor, are usually asymptomatic but may present with intussception. Primary malignancies of the small intestine, including adenocarcinoma, leiomyosarcoma, carcinoid, and lymphoma, may present with intestinal obstruction, jaundice, bleeding, or pain. Extraintestinal neoplasms may involve the intestine via contiguous spread or peritoneal metastasis. Hematogenous metastases to the intestine from an extraintestinal primary are unusual and are most typical of melanoma. Because the small intestine is relatively inaccessible to routine endoscopy, diagnosis of small intestinal neoplasms is often delayed for months after onset of symptoms. When the diagnosis is suspected, enteroclysis is the most useful imaging study. Small bowel endoscopy (enteroscopy is increasingly widely available and may permit earlier, non-operative diagnosis.

  8. Primary malignant small bowel tumor

    International Nuclear Information System (INIS)

    Small bowel tumors are rarely detected unless there is intestinal obstruction or bleeding. In the seven years 1982-1988, at Kosin Medical Center, 25 primary malignant small bowel tumors were studied radiographically with barium and / or computed tomography (CT). CT revealed gastrointestinal abnormalities in 20 patients. In ten, lesion were identified by upper G-I series, in 15 by small bowel series, and in addition, in 3 by colon enema. The most common malignant small bowel tumor was adenocarcinoma (N=15) and was next common lymphoma (N=7). On barium study, primary adenocarcinoma appeared as an irregular stricture (66.7%) and polypoid mass with intussusception was most prominent finding in lymphoma. Leiomyosarcoma appeared as an exophytic mass with excavation or ulceration. CT was found to be accurate in detecting wall thickening, complications and other associated findings. In conclusion, barium study was useful in the diagnosis of primary malignant small bowel tumor and CT was more accurate in detecting secondary findings

    Small bowel intubation is a useful method in the non-operative decompression of small bowel obstruction and enteral hyperalimentation in malnourished patients. We have tried small bowel intubation with Ventrol tube guided by small bowel enteroclysis guide wire (Bilbao-Dotter wire) in 12 patients. Ten cases were successfully intubated. In 11 cases of bowel obstruction, 9 cases were intubated and 8 cases were effectively drained. One malnourished patient was improved in nutritional state after enteral hyperalimentation through the intubated tube. We believe this method is an easy and time-saving method in the small bowel decompression

  16. CT findings in acute small bowel diverticulitis

    International Nuclear Information System (INIS)

    Small bowel diverticulitis is a rare cause of an acute abdomen. Originating from acquired diverticula of the jejunum, less often of the ileum, or Meckel diverticulum, the symptoms are non-specific, simulating other acute inflammatory disorders, such as appendicitis, cholecystitis or colonic diverticulitis. The diagnosis of small bowel diverticulitis is solely based on radiologic findings, with computed tomography (CT) regarded as the method of choice. In recent years, a number of case reports have described the spectrum of the CT features in acute small bowel diverticulitis and its dependence on the severity of the inflammatory process. Typical findings are an inflamed diverticulum, inflammatory mesenteric infiltration, extraluminal gas collection and mural edema of adjacent small bowel loops with resultant separation of bowel loops. An enterolith is rarely found in an inflamed diverticulum. Complications include abscesses, fistulae, small bowel obstruction and free perforation with peritonitis. Small bowel diverticulitis can be a diagnostic problem if it involves the terminal ileum or Meckel's diverticulum. For preoperative confirmation of the presumed diagnosis of small bowel diverticulitis on CT, an enteroclysis for acquired diverticula or a technetium scan for Meckel's diverticulum should be performed. We present the CT findings in three patients of acute small bowel diverticulitis, two affecting the jejunum and one a Meckel's diverticulum. (orig.)

  17. Diverticular disease: A therapeutic overview

    Directory of Open Access Journals (Sweden)

    Antonio Tursi

    2010-02-01

    Full Text Available Formation of colonic diverticula, via herniation of the colonic wall, is responsible for the development of diverticulosis. When diverticulosis becomes symptomatic, it becomes diverticular disease. Diverticular disease is common in Western and industrialized countries, and it is associated with numerous abdominal symptoms (including pain, bloating, nausea, diarrhea, and constipation. Standard medical therapies with antibiotics are currently recommended for patients affected by diverticular disease. However, changing concepts on the pathophysiology of the disease suggest that diverticular disease may share many of the hallmarks of inflammatory bowel diseases. On this basis, the addition of therapies using mesalazine and probiotics may enhance treatment efficacy by shortening the course of the disease and preventing recurrences.

    Quigley, E M

    2012-02-03

    Recently, the small intestine has become the focus of investigation as a potential site of dysmotility in the irritable bowel syndrome (IBS). A number of motor abnormalities have been defined in some studies, and include \\'clustered\\' contractions, exaggerated post-prandial motor response and disturbances in intestinal transit. The significance of these findings remains unclear. The interpretation of available studies is complicated by differences in subject selection, the direct influence of certain symptoms, such as diarrhoea and constipation, and the interference of compounding factors, such as stress and psychopathology. Dysmotility could also reflect autonomic dysfunction, disturbed CNS control and the response to heightened visceral sensation or central perception. While motor abnormalities may not explain all symptoms in IBS, sensorimotor interactions may be important in symptom pathogenesis and deserve further study.

    2006-01-01

    Collagenous colitis (CC) is a chronic inflammatory bowel disease that affects the colon. However, some patients with CC present with accompanying pathologic small-bowel manifestations such as coeliac disease, defects in bile acid absorption and histopathologic changes in small-intestinal biopsies, indicating that CC is a pan-intestinal disease. In small-intestinal disease, the intestinal barrier function may be impaired, and the permeability of the small intestine altered. The purpose of this research was to study small-bowel function in patients with CC as expressed by intestinal permeability.

  1. Magnetic resonance imaging of the small bowel

    International Nuclear Information System (INIS)

    Magnetic Resonance Imaging of the Small Bowel (MR Enterography, or MRE) is becoming increasingly popular as the first imaging modality for the diagnosis and follow-up of small bowel diseases. The inherent advantages of MRI, including excellent soft tissue contrast, multiplanar capability and lack of ionising radiation are well known. In addition, the use of luminal contrast agents in MRE has the added advantage of demonstrating the lumen and the wall directly, something not possible to achieve with conventional small bowel barium follow-through imaging. This review will highlight recent technical advances to this low cost, simple technique which is easily achievable in all hospitals. It will also review normal and abnormal radiological findings and highlight the value of this technique to both the clinician and patient alike in the investigation of small bowel disease.

    Vast majority of bowel obstruction is due to postoperative adhesions, malignancy, intestinal inflammatory disease, and hernias; however, knowledge of other uncommon causes is critical to establish a prompt treatment and decrease mortality. Xanthomatosis is produced by accumulation of cholesterol-rich foamy macrophages. Intestinal xanthomatosis is an uncommon nonneoplastic lesion that may cause small bowel obstruction and several cases have been reported in the English literature as obstruction in the jejunum. We report a case of small intestinal xanthomatosis occurring in a 51-year-old female who presented with one day of copious vomiting and intermittent abdominal pain. Radiologic images revealed jejunal loop thickening and inflammatory changes suggestive of foreign body obstruction, diagnostic laparoscopy found two strictures at the jejunum, and a pathologic examination confirmed a segmental small bowel xanthomatosis. This case illustrates that obstruction even without predisposing factors such as hyperlipidemia or lymphoproliferative disorders. PMID:26167322

    Full Text Available Context: Spontaneous perforation of rectum is a rare event; however evisceration of the small bowel through the perforated site without predisposing factors is extremely rare, complex and worth reporting. Case report: A 14 years old presented to us apparently as a case of intussception. The operative findings revealed it to be a case of spontaneous perforation of rectum with evisceration of the small bowel through the perforation. Conclusion: Sudden increase in the intra-abdominal pressure leads to the perforation in the chronically deranged rectal wall and pushes the small bowel loops into the pelvis and through the perforated rectum to appear transanally.

    Full Text Available AIM: To investigate morphological changes of intestinal smooth muscle contractile fibres in small bowel atresia patients. METHODS: Resected small bowel specimens from small bowel atresia patients (n = 12 were divided into three sections (proximal, atretic and distal. Standard histology hematoxylin-eosin staining and enzyme immunohistochemistry was performed to visualize smooth muscle contractile markers ?-smooth muscle actin (SMA and desmin using conventional paraffin sections of the proximal and distal bowel. Small bowel from age-matched patients (n = 2 undergoing Meckel’s diverticulum resection served as controls. RESULTS: The smooth muscle coat in the proximal bowel of small bowel atresia patients was thickened compared with control tissue, but the distal bowel was unchanged. Expression of smooth muscle contractile fibres SMA and desmin within the proximal bowel was slightly reduced compared with the distal bowel and control tissue. There were no major differences in the architecture of the smooth muscle within the proximal bowel and the distal bowel. The proximal and distal bowel in small bowel atresia patients revealed only minimal differences regarding smooth muscle morphology and the presence of smooth muscle contractile filament markers. CONCLUSION: Changes in smooth muscle contractile filaments do not appear to play a major role in postoperative motility disorders in small bowel atresia.

  7. Use of CT Enterography for Small Bowel Pathology:Experience and Findings in 90 Patients

    International Nuclear Information System (INIS)

    Proper evaluation of the small intestine is achieved with the combination of intravenous contrast medium and large volume of neutral contrast medium administered orally to stretch the intestinal lumen and produce images for the assessment of the lumen, thickness and pattern of enhancement of the small intestine walls. Materials and methods: Between May 2007 and February 2009 we retrospectively collected 90 cases of mainly outpatients who consulted our clinic. They were prepared taking a liquid diet for 24 hours that had no residue and complete fasting 4 hours prior to the examination. A total of 2000 cc of water was administrated orally (divided in 500 cc, 75, 65, 25 and 15 minutes prior to the examination). Then 100 cc of contrast medium (OptirayTM ) were administered intravenously, at a rate of 4 cc/sec. An early arterial phase was performed 20 seconds after injection, and a portal phase 60 seconds after IV contrast administration. The studies were performed in a 16 channels, General Electric multidetector scanner, with 3.0 mm slices, with multiplanar reconstructions and MIP. Results: The studies were interpreted by a group body imaging radiologists. The most frequent findings were: diverticular disease, cystic lesions, neoplasia, Crohn's disease,ileitis, mechanical obstruction, hiatal hernia, cholelithiasis, hepatic hemangiomas, duodenal diverticulum, polyposis, intestinal mal rotation, and active bleeding. Conclusions: CT enterography is a useful and noninvasive technique for diagnosing small bowel disorders, allowing, in most cases, a satisfactory distension of the small bowel without the use of an enteral tube.

One of these, reported thus far in only very few patients, is obstruction caused by secondary tumors, i.e. metastases from other organs to the small bowel wall. As cancer patients live longer with improved therapy, physicians are more likely to cope with rare phenomena of neoplasms, such as small bowel obstruction caused by secondary tumors. We hereby present a review of the relevant medical literature. The goal of this article is to define current knowledge on this phenomenon, with emphasis on its epidemiology and clinical characteristics, and to increase the awareness of the clinician treating cancer patients of such possibility.

  10. The radiolesions of the small bowel

    International Nuclear Information System (INIS)

    The irradiation of the pelvic abdominal cancers extends beyond the centre of the tumour and may induce actinic digestive lesions. The bowel and more rarely the small bowel -which is the subject-matter of our study- are concerned by those radiolesions that are favoured by therapeutic overdose, post-operative adhesions fastening the bows, radio-surgical or chemicostatic associations, and lastly by vascular or nutritive deficiencies. One may distinguish between two kinds of lesions, depending on the lapse of time before their coming out and on the symptoms. The early or acute types are characterized by a radio-mucitis and give an exsudative enteropathy with anorexia, vomiting, diarrhoea and loss of weight, of which the diagnosis is easy because it occurs during the irradiation and lessens at the end of the treatment. The late radiolesions of the small bowel are characterized by sclerosis and chronic endarteritis and, after a longlasting period of latency, give varied symptoms: disordered intestinal transit which sometimes is irreversible, perforation, fistula, syndrome of malabsorption, giving often rise to be mistaken for a recurrence of the cancer. The treatment varies whether the lesion is segmental or diffuse. In the first case, the failure of the medical means accounts for the surgical cutting away or the internal derivation; in the second case, the digestive mutilation which would result from an enlargement of the lesion commands to be more cautious and to call for the methods of parenteral feeding and digestive setting to rest

    A fecaloma refers to a mass of accumulated feces that is much harder than a mass associated with fecal impaction. Fecalomas are usually found in the rectosigmoid area. A 10-year-old male with chronic constipation was admitted because of increasing abdominal pain. An abdominal computed tomography scan and a simple abdominal x-ray revealed rapidly evolving mechanical obstruction in the small intestine. Most of the fecalomas are successfully treated by conservative methods such as laxatives, enemas and rectal evacuation. When conservative treatments have failed, surgical intervention may be needed. In this case, an emergency operation was performed and a 4×3×2.5 cm fecaloma was found in the distal ileum. We thus report a case of ileal fecaloma inducing small bowel obstruction in a patient with chronic constipation, who required surgical intervention. When symptoms of acute small intestinal obstruction develop in a patient with chronic constipation, a fecaloma should be considered in differential diagnosis. PMID:26473140

    Gastrointestinal angiodysplasias recurrently bleed, accounting for 3-5% of obscure gastrointestinal bleeding. The advent of small bowel capsule endoscopy (SBCE) has led to an increased recognition of small bowel angiodysplasias (SBAs) but little is known about their etiology. Previous small cohorts and case reports suggest an equal gender incidence and associations with cardiovascular disease, renal impairment, and coagulopathies.

CT showed irregular wall thickening, loss of mural stratification and aneurysmal dilatation of the distal ileum. Small bowel series showed aneurysmal dilatations, interloop adhesion with traction and abrupt angulation.

    About one-half of patients with meconium ileus (MI) present with a complication such as volvulus, atresia, meconium peritonitis or giant cystic meconium peritonitis. The treatment of these complications requires surgery. However, the preoperative diagnosis of complicated MI is difficult. We describe two neonates with complicated small-bowel obstruction, one with MI related to cystic fibrosis and the other not related to cystic fibrosis. In both, contrast enema depicted a spiral appearance of the distal small bowel, which at surgery proved to be the result of volvulus associated with antenatal bowel perforation. This appearance of the small bowel on contrast enema in this clinical setting has not been previously described. The recognition of this spiral appearance of the distal small bowel suggests the need for surgery. (orig.)

    CD is a chronic inflammatory disorder associated to mucosal and transmural inflammation of the bowel wall. It is well known that CD can affect the entire gastrointestinal. Therefore, ileocolonoscopy and biopsies of the terminal ileum as well as of each colonic segment to look for microscopic evidence of CD are the first-line procedures to establish the diagnosis. However, it has been observed that up to 30% of the patients have only small bowel involvement. Evaluation of the small bowel has b...

    Abstract Ultrasonography is a standard, noninvasive modality used to evaluate patients with gastrointestinal diseases. This study assessed the usefulness of ultrasonography in the detection of small bowel tumors. This study enrolled 558 consecutive patients (295 males, 263 females; mean age 71.1 years) who underwent ultrasonography before capsule endoscopy and/or balloon-assisted endoscopy. Ultrasonographic detection of small bowel tumors was compared with detection by capsule endoscopy and/or balloon-assisted endoscopy. In addition, factors affecting small bowel tumor detection by ultrasonography and clinical characteristics of patients with small bowel tumors undetected by ultrasonography were evaluated. Ninety-seven tumors (52 benign, 45 malignant) detected by capsule endoscopy and/or balloon-assisted endoscopy were retrospectively analyzed. The sensitivity and specificity of ultrasonography in the detection of small bowel tumors were 50.5% (47/93) and 100% (465/465), respectively. If we restricted patients to those with a tumor >20?mm in size, its detection ratio would become higher (91.7%): the ratio of submucosal tumor >20?mm in size was 85.7% (6/7) and that of partial and circumferential ulcerative tumors >20?mm in size was 96.9% (31/32), respectively. Small bowel tumors detected by ultrasonography (mean 33.2?mm) were significantly larger than those undetected by ultrasonography (mean 8.7?mm). The percentage of small bowel tumors located in the ileum detected by ultrasonography (70.6%) was significantly higher than those undetected by ultrasonography (29.4%). Of the 46 small bowel tumors undetected by ultrasonography, 42 (91.3%) were benign tumors with good clinical prognosis. Ultrasonography is a useful modality for detecting larger small bowel tumors and ulcerative lesions. Ultrasonography should be considered a first-line modality for patients suspected of having small bowel tumors, because most small bowel tumors undetected by ultrasonography were benign tumors with good clinical prognosis.

  20. Multiphasic MDCT in small bowel volvulus

    International Nuclear Information System (INIS)

    Objective: Evaluate the use of MDCT with 3D CT angiography (CTA) and CT portal venography (CTPV) reconstruction for the diagnosis of small bowel volvulus (SBV). Methods: Multiphasic MDCT findings in nine patients (seven males and two females, age range 2-70) with surgically proven SBV were retrospectively reviewed. Non-contrast and double phase contrast enhanced MDCT including 3D CTA and CTPV reconstruction were performed in all the patients. Two experienced abdominal radiologists evaluated the images and defined the location, direction and degree of SBV. Results: On axial MDCT images, all cases show segmental or global dilatation of small intestine. Other findings include circumferential bowel wall thickening in eight cases, halo appearance and hyperemia in seven cases, whirl sign in six cases, beak-like appearance in six cases, closed loops in six cases and ascites in one case. CTA/CTPV showed abnormal courses involving main trunks of superior mesenteric artery (SMA) and superior mesenteric vein (SMV) in seven cases, with or without distortion of their tributaries. Normal course of SMA but abnormal course of SMV was seen in the other two cases. Of all the nine cases, whirl sign was seen in six cases and barber's pole sign in five cases. Dilated SMV was observed in eight cases and abrupt termination of SMA was found in one case. Compared with surgical findings, the location, direction and degree of SBV were correctly estimated in all cases based on CTA/CTPV. Conclusion: Multiphasic MDCT with CTA/CTPV reconstruction can play an important role in the diagnosis of SBV. The location, direction and degree of SBV can all be defined preoperatively using this method.

  1. Imaging differentiation of phytobezoar and small-bowel faeces: CT characteristics with quantitative analysis in patients with small- bowel obstruction

    International Nuclear Information System (INIS)

    The objective is to use multidetector computed tomography (MDCT) to differentiate phytobezoar impaction and small-bowel faeces in patients with small-bowel obstruction (SBO). We retrospectively reviewed 91 consecutive SBO patients with surgically proven phytobezoars (n = 31) or adhesion with small-bowel faeces (n = 60). Two readers blinded to the diagnosis recorded the following MDCT features: degree of obstruction, transition point, mesenteric fatty stranding, intraperitoneal fluid, air-fluid level, pneumatosis intestinalis, and portal venous gas. MDCT measurements of the food debris length, attenuation, luminal diameter, and wall thickness of the obstructed bowel were also compared. A higher grade of obstruction with an absence of mesenteric fatty stranding and intraperitoneal fluid was more commonly seen in the phytobezoar group than in the small-bowel faeces group (p < 0.01). The food debris length (phytobezoar, 5.7 ± 2.8 cm; small-bowel feces, 20.3 ± 7.9 cm, p < 0.01) and mean attenuation (phytobezoar, -59.6 ± 43.3 Hounsfield units (HU); small-bowel faeces, 8.5 ± 7.7 HU, p <0.01) were significantly different between the two groups. The ROC curve showed that food debris length <9.5 cm and mean attenuation value < -11.75 HU predicted phytobezoar impaction. MDCT features with measurements of the food debris length and mean attenuation assist the differentiation of phytobezoar impaction and small-bowel faeces. (orig.)

  3. MRI of the small bowel: can sufficient bowel distension be achieved with small volumes of oral contrast?

    International Nuclear Information System (INIS)

    Sufficient luminal distension is mandatory for small bowel imaging. However, patients often are unable to ingest volumes of currently applied oral contrast compounds. The aim of this study was to evaluate if administration of low doses of an oral contrast agent with high-osmolarity leads to sufficient and diagnostic bowel distension. Six healthy volunteers ingested at different occasions 150, 300 and 450 ml of a commercially available oral contrast agent (Banana Smoothie Readi-Cat, E-Z-EM; 194 mOsmol/l). Two-dimensional TrueFISP data sets were acquired in 5-min intervals up to 45 min after contrast ingestion. Small bowel distension was quantified using a visual five-grade ranking (5 very good distension, 1 = collapsed bowel). Results were statistically compared using a Wilcoxon-Rank test. Ingestion of 450 ml and 300 ml resulted in a significantly better distension than 150 ml. The all-over average distension value for 450 ml amounted to 3.4 (300 ml: 3.0, 150 ml: 2.3) and diagnostic bowel distension could be found throughout the small intestine. Even 45 min after ingestion of 450 ml the jejunum and ileum could be reliably analyzed. Small bowel imaging with low doses of contrast leads to diagnostic distension values in healthy subjects when a high-osmolarity substance is applied. These findings may help to further refine small bowel MRI techniques, but need to be confirmed in patients with small bowel disorders. (orig.)

    Multidetector computed tomography (MDCT) has largely supplanted other available radiologic modalities in the evaluation of a wide variety of different vascular and inflammatory abnormalities of the small bowel, with computed tomography angiography (CTA) playing a major role in the diagnostic efficacy of MDCT for these diseases. Improvements in CTA imaging have proved particularly valuable in the evaluation of small bowel vascular and inflammatory disorders, diagnoses in which arterial phase images might be able to offer greater information than standard venous phase imaging. This article details the MDCT imaging findings of several small bowel vascular and inflammatory disorders. PMID:26654393

  6. Oral contrast agents for small bowel MRI: comparison of different additives to optimize bowel distension

    International Nuclear Information System (INIS)

    The purpose of this study was to compare two osmotic carbohydrate sugar alcohols (mannitol 2.5% and sorbitol 2.5%, 2.0%, and 1.5% watery solutions) in combination with 0.2% locust bean gum (LBG) for small bowel distension for MR imaging. Small bowel distension was quantified on coronal 2D TrueFISP images by measuring the diameters of 16 small bowel loops in each of 12 healthy subjects (age range 31-55 years). Additionally, the grade of small bowel distension was rated qualitatively. Patient acceptance concerning nausea, vomiting, flatulence, and diarrhea was noted for each solution, and all results were compared by a Wilcoxon test or t test, respectively. The ingestion of water combined with LBG and either 2.5% mannitol or 2.0% sorbitol showed the best distension of the small bowel. The lowest side effect rate was observed following ingestion of sorbitol in a concentration of 2.0 and 1.5%. Based on these data, we recommend a combination of LBG and 2% sorbitol use for optimal bowel distension and minimal side effects resulting in enhanced patient acceptance. (orig.)

    Purpose: To assess the normal small bowel parameters, namely bowel diameter, bowel wall thickness, number of folds (valvulae connivientes) per 2.5 cm (in.), fold thickness and interfold distance per small bowel segment (duodenum, jejunum, proximal ileum, distal ileum and terminal ileum) on MR enterography. Materials and methods: Between September 2003 and January 2008, 280 MR enterography examinations were performed for investigation of known or suspected small bowel pathology. 120 of these examinations were normal. Sixty-five (m = 29, f = 36, mean age = 34 years, range = 17-73 years) of 120 examinations without a prior small bowel diagnosis, with no prior or subsequent abnormal radiology or endoscopy examinations, no prior small bowel surgery and with a minimum 3 years follow-up demonstrating normality were retrospectively evaluated for the described small bowel parameters. Results: We found the mean diameter of the duodenum to be 24.8 mm (S.D. = 4.5 mm), jejunum to be 24.5 mm (S.D. = 4.2 mm), proximal ileum to be 19.5 mm (S.D. = 3.6 mm), distal ileum to be 18.9 mm (S.D. = 4.2 mm) and terminal ileum to be 18.7 mm (S.D. = 3.6 mm). The number of folds per 2.5 cm varied from 4.6 in the jejunum to 1.5 in the terminal ileum. The fold thickness varied from 2.1 mm in the duodenum to 1.8 mm in the terminal ileum. The small bowel parameters gradually decreased in size from the duodenum to the smallest measurements which were in the terminal ileum. The bowel wall is similar in size throughout the small bowel measuring 1.5 {+-} 0.5 mm. Conclusion: These results provide the mean, range of normality and standard deviation of the small bowel parameters per segment on the current population on MR enterography. From our experience, knowledge of these parameters is extremely helpful and essential in the everyday assessment of MR enterography studies.

    2012-01-01

    Full Text Available Double balloon enteroscopy (DBE is a revolutionary procedure in which the entire small bowel can be visualized endoscopically. DBE has the advantage of both diagnostic and therapeutic capabilities in the setting of small bowel neoplasms and vascular malformations. We present a unique case of a 76-year-old female who underwent small bowel DBE tattoo marking of a distal small bowel tumor complicated by development of severe abdominal pain postprocedure secondary to bowel air embolism into the mesenteric veins. Mesenteric air can be seen after other endoscopic procedures such as biopsy, mucosal clip placement and polypectomy, or following a colonoscopy. Mesenteric air embolism following small bowel tattooing procedure has not been previously reported in the literature. Mesenteric air when present may be attributed to mesenteric ischemia and can subject the patient to unnecessary surgical intervention if misdiagnosed. Thus, this report holds significance for the radiologist as computed tomography (CT findings of mesenteric air embolism must be evaluated in the context of appropriate clinical history before treatment decisions are made.

  10. Transient small bowel angioedema due to intravenous iodinated contrast media

    2012-01-01

    Full Text Available Three cases of transient proximal small bowel angioedema induced by intravenous administration of nonionic iodinated contrast media (CM are presented. Computed tomography (CT images in the venous phase displayed the proximal small bowel with circumferential thickening of the wall including the duodenum and proximal segment of the jejunum. The bowel wall was normal in non-enhanced images, and normal or inconspicuous in arterial phase enhanced images. In one of the three cases, the bowel wall was thickened in venous phase but disappeared in the 40 s delayed phase images. No filling defect was seen in the lumen of the superior mesenteric artery and vein. No peritoneal effusion or mesentery abnormality was found. Each of these patients reported only mild abdominal discomfort and recovered without specific treatment within a short time. Only one patient suffered mild diarrhea after scanning which had resolved by the following day. The transient anaphylactic small bowel angioedema due to intravenous iodinated contrast media was easily diagnosed based on its characteristic CT findings and clinical symptoms. Differential diagnosis may include inflammatory and ischemic bowel disease, as well as neoplasms. A three-phase CT protocol and good understanding of this disorder are fundamentally important in the diagnosis of this condition. The supposed etiology behind the transient anaphylactic reaction to intravenous administration of iodinated CM in small bowel is similar to other CM-induced hypersensitive immediate reactions. The predilection location of transient anaphylactic bowel angioedema is the small intestine, particularly the proximal segment. A speculated cause may be the richer supply of vessels in the small intestine, ample mucous folds and loose connective tissue in the duodenum and the jejunum.

    We wanted to describe the CT findings of small bowel anisakiasis with the pathologic correlation. Four patients with surgically and pathologically proven small bowel anisakiasis were included in this retrospective study. They were three men and one woman and their ages ranged from 28 to 43 years (mean age: 38 years). We evaluated their clinical, CT and histological findings. All the patients had a history of ingesting raw fish within 24 hours from the time of symptom onset. They complained of abdominal pain (n=4), nausea (n=4), vomiting (n=2) and diarrhea (n=1). Physical examination revealed tenderness (n=4), rebound tenderness (n=4) and increased bowel sounds (n=3). Leukocytosis was noted in all the patients on the laboratory examination. None of the patients showed eosinophilia. The CT findings were segmental small bowel wall thickening with preserved layering (n=4), focal segmental luminal narrowing with proximal dilatation (n=4), peritoneal thickening (n=3), mesenteric or omental infiltration (n=4) and varying degrees of ascites (n=4). On the histopathologic examination, they revealed an infiltration of eosinophils (n=4) in all layers of the bowel wall with severe edema. The larvae were found on surgico-pathologic examination in all the cases. The CT findings may be helpful to make the specific diagnosis of small bowel anisakiasis in a patient with the clinical findings of an acute abdomen and a history of eating raw fish

    In three patients with ileus CT showed a whirl sign in which the bowel and mesenteric folds encircled the superior mesenteric vein in a whirl-like pattern. Two patients were confirmed surgically to have small-bowel volvulus arising from postoperative adhesions. The whirl sign is useful in decision-making about the need for surgery. A CT examination should be performed for patients with ileus of unknown cause. (orig.)

    2011-03-01

    Full Text Available Merkel cell carcinoma (MCC is an uncommon cutaneous malignant tumor that presents as a rapidly growing skin nodule on sun-exposed areas of the body. MCC is aggressive with regional nodal and distant metastases to the skin, lung, and bones. There have been no reports of metastatic MCC to the mesentery and 6 reports describing metastasis to the small intestine. We present a case of metastatic MCC to the mesentery with infiltration to the small bowel, 8 years after original tumor resection. This is the 5th metastasis and it encased the small bowel resulting in a hair-pin loop contributing to the unusual clinical presentation. Although MCC metastatic to the bowel is uncommon, it is not rare. It is important to recognize the unusual manifestations of this disease as they are becoming more common in the future. Routine radiologic surveillance and thorough review of systems are important to patient follow-up.

    2013-10-16

    Crohn's disease (CD) is a chronic inflammatory condition of the gastrointestinal tract resulting in inflammation, stricturing and fistulae secondary to transmural inflammation. Diagnosis relies on clinical history, abnormal laboratory parameters, characteristic radiologic and endoscopic changes within the gastrointestinal tract and most importantly a supportive histology. The article is intended mainly for the general gastroenterologist and for other interested physicians. Management of small bowel CD has been suboptimal and limited due to the inaccessibility of the small bowel. Enteroscopy has had a significant renaissance recently, thereby extending the reach of the endoscopist, aiding diagnosis and enabling therapeutic interventions in the small bowel. Radiologic imaging is used as the first line modality to visualise the small bowel. If the clinical suspicion is high, wireless capsule endoscopy (WCE) is used to rule out superficial and early disease, despite the above investigations being normal. This is followed by push enteroscopy or device assisted enteroscopy (DAE) as is appropriate. This approach has been found to be the most cost effective and least invasive. DAE includes balloon-assisted enteroscopy, [double balloon enteroscopy (DBE), single balloon enteroscopy (SBE) and more recently spiral enteroscopy (SE)]. This review is not going to cover the various other indications of enteroscopy, radiological small bowel investigations nor WCE and limited only to enteroscopy in small bowel Crohn's. These excluded topics already have comprehensive reviews. Evidence available from randomized controlled trials comparing the various modalities is limited and at best regarded as Grade C or D (based on expert opinion). The evidence suggests that all three DAE modalities have comparable insertion depths, diagnostic and therapeutic efficacies and complication rates, though most favour DBE due to higher rates of total enteroscopy. SE is quicker than DBE, but lower complete enteroscopy rates. SBE has quicker procedural times and is evolving but the least available DAE today. Larger prospective randomised controlled trial's in the future could help us understand some unanswered areas including the role of BAE in small bowel screening and comparative studies between the main types of enteroscopy in small bowel CD.

Management of small bowel CD has been suboptimal and limited due to the inaccessibility of the small bowel. Enteroscopy has had a significant renaissance recently, thereby extending the reach of the endoscopist, aiding diagnosis and enabling therapeutic interventions in the small bowel. Radiologic imaging is used as the first line modality to visualise the small bowel. If the clinical suspicion is high, wireless capsule endoscopy (WCE is used to rule out superficial and early disease, despite the above investigations being normal. This is followed by push enteroscopy or device assisted enteroscopy (DAE as is appropriate. This approach has been found to be the most cost effective and least invasive. DAE includes balloon-assisted enteroscopy, [double balloon enteroscopy (DBE, single balloon enteroscopy (SBE and more recently spiral enteroscopy (SE]. This review is not going to cover the various other indications of enteroscopy, radiological small bowel investigations nor WCE and limited only to enteroscopy in small bowel Crohn’s. These excluded topics already have comprehensive reviews. Evidence available from randomized controlled trials comparing the various modalities is limited and at best regarded as Grade C or D (based on expert opinion. The evidence suggests that all three DAE modalities have comparable insertion depths, diagnostic and therapeutic efficacies and complication rates, though most favour DBE due to higher rates of total enteroscopy. SE is quicker than DBE, but lower complete enteroscopy rates. SBE has quicker procedural times and is evolving but the least available DAE today. Larger prospective randomised controlled trial’s in the future could help us understand some unanswered areas including the role of BAE in small bowel screening and comparative studies between the main types of enteroscopy in small bowel CD.

    Full Text Available Malignant melanoma (MM is an unpredictable tumour that can metastasise to any organ, and is well known for its widespread dissemination. The incidence of metastases to the gastro-intestinal (GI tract is well documented; this, however, is a late manifestation of the disease with an overall poor prognosis. Most GI metastases are asymptomatic and are only discovered on postmortem, with the majority in the small bowel. The presenting symptoms are usually of obstruction or intussusception; GI bleeding is also common. Fistula formation with the small bowel is rare; ours is believed to be the second case documented.

    Solitary fibrous tumor (SFT) which is an extremely rare clinical entity has been reported infrequently. Most commonly it is distinguished into pleural and extrapleural forms, with same morphological resemblance. There has been many literatures reported regarding extrapleural form of SFT but few cases of SFT originating from small bowel mesentery have been reported till now. We here report one case of SFT of small bowel mesentery with some eventful postoperative bowel obstruction and literature review. PMID:26617912

    Objective: Celiac disease (CD) is a common, lifelong disease with small bowel malabsorption based on genetically conditioned gluten intolerance. The clinical manifestation could be very heterogeneous. The proof of celiac disease is now based mainly on clinical and laboratory (antibodies and enterobiopsy) signs, which are in some cases problematic and inconvenient. Materials and methods: In our study we have examined 250 patients with suspection or with proven celiac disease and we evaluated specific ultrasound small bowel changes in this group. In the next step, we chose 59 patients with laboratory proved celiac disease and we statistically compared ultrasound, other laboratory and clinical findings in different forms and stages of the disease. Results: Specific small bowel pathologies in patients with celiac disease (like changes of intestinal villi in different parts of small bowel, abnormal peristalsis and mesenterial lymphadenopathy) can be well visualized by ultrasound and in combination with clinical and laboratory signs ultrasound examination could have an important role in screening, determination of diagnosis and monitoring of patients with different forms of celiac disease.

    Full Text Available Abstract Background Resection of peritoneal metastases has been shown to improve survival in patients with abdominal metastatic disease from abdominal or extra abdominal malignancy. This study evaluates the benefit of peritoneal metastatic resection in patients with malignant small bowel obstruction and a past history of treated cancer. Patients and methods Patients undergoing laparotomy for resection of peritoneal metastases from recurrence of previous cancer between 1992–2003 were reviewed retrospectively. Data were collected about type of primary cancer, interval to recurrence, extent of the disease and completeness of resection, morbidity and mortality and long-term survival. Results Between 1992 and 2003 there were 79 patients (median age 62, range 19–91 who had laparotomy for small bowel obstruction due to recurrent cancer. The primary cancer was colorectal (31, gynaecologic cancer (19, melanoma (16 and others (13. Overall, the rate of complications was 35% and mortality was 10%. Median survival was 5 months; patients with history of colorectal cancer had better survival than other cancer (median survival 7 months vs. 4 months; p = 0.02. Multivariate analysis showed that the extent of recurrent disease was the only factor that affected overall survival. Conclusion Laparotomy for small bowel obstruction is a worthwhile option for patients with malignant small bowel obstruction. Although it is associated with significant morbidity and mortality it offers a reasonable survival benefit in particular for patients with completely resectable disease.

  6. Capsule endoscopy and imaging tests in the elective investigation of small bowel disease

    International Nuclear Information System (INIS)

    Capsule endoscopy enables high-resolution depiction of small bowel mucosa and has been shown, by several studies, to have a high diagnostic yield in a variety of small bowel diseases. In this review, we critically assess the contributions of capsule endoscopy and imaging tests in common small bowel disorders. Radiological tests that only assess the small bowel mucosa will be less useful in the era of capsule endoscopy

  7. Abnormalities of small bowel and colon in systemic sclerosis

    International Nuclear Information System (INIS)

    A series of 21 subjects (2 males and 19 females) affected with systemic sclerosis, was examined by small bowel (oral and intubation methods) and colon enema. The underlying process responsible for abnormalities in the small bowel and colon in systemic sclerosis is a variable and pacthy destruction of the muscularis propria, that produces the structural and functional changes detected on X-ray: Pathologic condition is the same affecting the esophagus. The scout film of the abdomen often reveals colonic distension and fecal impaction, so that it may be quite difficult to prepare adequately the patients for a barium enema. Peristalsis may be virtually absent in short segments, and transit time may be several time longer than that in normal patients. For these reasons, intestinal pseudo-obstruction may appear in systemic sclerosis. The observed radiographic changes are: 1) in the small bowel: a) dilatation of the gut, especially in its proximal portions (duodenum and jejunum), in which the valvulae conniventes are straightened, normal or thinned; b) presence of diverticula, 2-4 cm in diameter, with hemispherical shape without the neck-like opening into the bowel lumen; 2) in the colon, the characteristic finding is an increase in size of individual haustra, forming sacculations or pseudo-diverticula, usually on the antemesenteric border of the transverse colon, better demonstrated on post-evacuation film. Moreover, loss of colonic haustration is also observed associated to colonic elongation and dilatation

  8. MR imaging of the small bowel in Crohn's disease

    International Nuclear Information System (INIS)

    MR and CT techniques optimized for small bowel imaging are playing an increasing role in the evaluation of small bowel disorders. Several studies have shown the advantage of these techniques over tradition barium fluoroscopic examinations secondary to improvements in spatial and temporal resolution combined with improved bowel distending agents. The preference of MR vs. CT has been geographical and based on expertise and public policy. With the increasing awareness of radiation exposure, there has been a more global interest in implementing techniques that either reduce or eliminate radiation exposure [Brenner DJ, Hall EJ. Computed tomography-an increasing source of radiation exposure. N Engl J Med 2007;357:2277-84]. This is especially important in patients with chronic diseases such as inflammatory bowel disease who may require multiple studies over a lifetime or in studies that require sequential imaging time points such as in assessment of gastrointestinal motility [Froehlich JM, Patak MA, von Weymarn C, Juli CF, Zollikofer CL, Wentz KU. Small bowel motility assessment with magnetic resonance imaging. J Magn Reson Imaging 2005;21:370-75]. A recent study showed that certain subgroups of patients with Crohn's disease may be exposed to higher doses of radiation; those diagnosed at an early age, those with upper tract inflammation, penetrating disease, requirement of intravenous steroids, infliximab or multiple surgeries [Desmond AN, O'Regan K, Curran C, et al. Crohn's disease: factors associated with exposure to high levels of diagnostic radiation. Gut 2008;57:1524-29]. Therefore it has been suggested that techniques that can reduce or eliminate radiation exposure should be considered for imaging [Brenner DJ, Hall EJ. Computed tomography-an increasing source of radiation exposure. N Engl J Med 2007;357:2277-84]. Owing to the excellent softtissue contrast, direct multiplanar imaging capabilities, new ultrafast breath-holding pulse sequences, lack of ionizing radiation and availability of a variety of oral contrast agents, MR is well suited to play a critical role in the imaging of small bowel disorders. In this article we will review the technical issues related to the performance of MR enterography and enteroclysis and discuss the role and controversies of using MR in the assessment of inflammatory bowel disease.

  9. Large Intraluminal Ileal Hematoma Presenting as Small Bowel Obstruction in a Child

    International Nuclear Information System (INIS)

    Intraluminal small bowel hematoma has been rarely reported in children, as a rare cause of small bowel obstruction. We present a case of an intraluminal ileal hematoma presenting as small bowel obstruction in a child. Computed Tomography (CT) indicated a large intraluminal hyperdense lesion in the distal ileum as the cause of small bowel obstruction. Abdominal ultrasonography (US) showed an echogenic mass-like lesion with multiple septa in the distal ileum. Small bowel obstruction due to a complicated cystic mass was provisionally diagnosed. Histopathologic examination of the resected mass suggested a submucosal ileal hematoma. Although intraluminal small bowel hematoma is rare in children, it can present as an intraluminal cystic mass and should be considered as a rare cause of small bowel obstruction. The US and CT findings of submucosal ileal hematoma could be useful for the diagnosis of such cases in the future

    The use of Naso-Jejunal (NJ) feeding is limited by difficulty in feeding tube placement. Patients have traditionally required transfer to Endoscopy or Radiology for insertion of small bowel feeding tubes, with clear resource implications. We hypothesised that the adoption of a simple bedside procedure would be effective and reduce cost. Clinical nutrition and nurse specialist personnel were trained in the 10\\/10\\/10 method of blind bedside NJ insertion.

    Late technical complications of composite liver/small bowel transplantation procedures are often complex and have not been well defined. Here we describe the unusual presentation and management of two cases of recurrent thrombocytopenia due to hypersplenism resulting from portacaval shunt stenosis. Both patients presented with portal hypertension late after composite liver/small bowel transplantation. One patient presented with recurrent bouts of upper gastrointestinal hemorrhage and was ultimately found to have a stenosis of her native portacaval shunt. After unsuccessful balloon dilatation of the anastomosis, a successful side-to-side distal splenorenal shunt was performed. The second patient presented with severe thrombocytopenia, the etiology of which was determined to be a short segment occlusion of the inferior vena cava between the native portacaval shunt and the piggyback outflow anastomosis of the liver graft. Total caval occlusion prevented balloon dilatation; the patient was relisted for transplantation but died of chronic rejection four months later. Recurrent portal hypertension is challenging in patients who have had combined liver/small bowel transplantation. Surgeons performing intestinal transplantation need to be increasingly aware of these possible late complications. PMID:12089720

  13. Interobserver agreement on the diagnosis of bowel ischemia. Assessment using dynamic computed tomography of small bowel obstruction

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the accuracy and interobserver variability of dynamic computed tomography (CT) for diagnosis of small bowel obstruction. A total of 115 patients with a CT diagnosis of small bowel obstruction were included. Two radiologists and two residents performed blinded, independent, retrospective reviews of CT studies. Attention was focused on the presence of reduced early enhancement of the bowel wall and closed loop obstruction. Results were correlated with surgical findings in 15 cases and clinical follow-up in 100 cases. Sensitivity and specificity were calculated, and kappa statistics were used to analyze interobserver agreement. In all, 13 cases were surgically confirmed small bowel ischemia. Sensitivity, specificity, positive predictive value, and negative predictive value for the diagnosis of ischemia were 85%, 96%-97%, 73%-79%, and 97%-98%, respectively, for radiologists and 69%-93%, 93%-95%, 63%-64%, and 96%-99%, respectively, for residents. For agreement in the interpretations of reduced early enhancement of bowel wall, closed loop obstruction, and presence of bowel ischemia, the values were 0.62, 0.71, and 0.80, respectively, between radiologists and 0.57-0.70, 0.63-0.74, and 0.56-0.68, respectively, between radiologists and residents. There was moderate or substantial agreement for the diagnosis of small bowel ischemia between radiologists and residents. However, there was substantial agreement for the presence of closed loop obstruction. (author)

    2009-05-01

    Full Text Available Small bowel obstruction in an oncology patient is a common and serios medical problem, associated with diagnostic and therapeutic dilemmas. We report a case of small bowel obstruction caused by a metastatic tumor secondary to bilateral recurrent ovarian cancer. The clinical diagnosis is difficult because of lack of specific signs and simptoms. The computed tomography becomes essential in the preoperative diagnostic. The treatment has two targets: to solve the obstruction and to control the metastatic desease. The case is particular because of the presence of a jejuno-colic intratumoral fistula. The anatomopathological examination reveals the character of metastatic tumor secondary to ovarian cancer. Good general status, with no severe comorbidities and the significant response to anti-cancer chemotherapy, make a good prognosis after radical resection of the metastasis. The posibility of a metastasis in the bowel wall as a potential cause of an obstruction requires a high level of suspipicion and sould be considered as a differential diagnosis in any patient with a history of cancer.

    Intussusceptions are defined as the telescoping of one segment of the gastrointestinal tract into an adjacent distal segment. In the small bowel, intussusceptions are typically caused by benign processes, but can occasionally be caused by inflammatory fibroid polyps, which often present as intussusception and bowel obstruction. These polyps are rare, benign, tumorous lesions in the gastrointestinal tract and are typically observed in the stomach, but can occur anywhere in the gastrointestinal tract. Any case of a jejunojejunal intussusception caused by inflammatory fibroid polyps is considered rare, and we report the case of a 51-year-old woman with an inflammatory fibroid polyp of the jejunum presenting as an intussusception who was successfully treated with a resection.

    Full Text Available Small bowel obstruction is a common surgical emergency but trichobezoar as an etiology, rarely reported. A seven year old school going female child presented with acute intestinal obstruction with a palpable and mobile mass in the abdomen. At exploration, a 10 cm long trichobezoar was found in the distal ileum which was removed through enterotomy. Postoperative course remained uneventful. Further probing revealed that child used to eat her own scalp hairs at the age of 2 years and the habit persisted for about 18 months which resulted in alopecia at that time. Later on she started showing normal behavior.

    Anisakiasis, a parasitic infection by larvae of the nematode Anisakis found in raw or undercooked saltwater fish, mostly involves stomach but rarely small intestine. We report a rare case of a 61-year-old man who presented with abdominal pain and developed small bowel obstruction caused by intestinal anisakiasis. Abdominal computed tomography revealed segmental edema of the intestinal wall with proximal dilatation. The patient underwent urgent laparotomy because strangulated small bowel obstruction was suspected. A localized portion of the intestine around jejunoileal junction was found to be erythematous, edematous, and hardened, which was resected. The resected specimen showed a linear whitish worm, Anisakis simplex, penetrating into the intestinal mucosa. It is often clinically challenging to consider intestinal anisakiasis in the differential diagnosis because of its nonspecific abdominal symptoms and findings. Although gastrointestinal anisakiasis is still rare in the United States, the incidence is expected to rise given the growing popularity of Japanese cuisine such as sushi or sashimi. Anisakiasis should be considered as one of the differential diagnoses in patients with nonspecific abdominal symptoms after consumption of raw or undercooked fish. PMID:23786678

    To evaluate the usefulness of CT for the diagnosis of the cause and localization of small bowel obstruction. Out of a group of children who underwent a CT examination for a suspected small bowel obstruction, 19 patients with confirmed underlying disorders were identified and included in the study. Neonates and patients with duodenal obstruction were excluded from the study. The CT findings were analyzed for the location of obstruction site, abnormalities of the mesentery and mesenteric vessels, bowel wall thickening, closed loop obstruction, and strangulation. The obstruction site was divided into five parts. The preoperative CT diagnosis was compared with the final diagnosis. Causes of small bowel obstruction were intussusception (n = 6), appendiceal perforation (n = 4), transmesenteric internal hernia (n = 2), postoperative bands (n = 1), idiopathic multiple bands (n = 1), a foreign body (n = 1), a small bowel adenocarcinoma (n = 1), Meckel's diverticulitis (n = 1), tuberculous peritonitis (n = 1) and Salmonella enteritis with bowel perforation (n = 1). The CT findings showed mesenteric vascular prominence (n = 13), omental or mesenteric infiltration (n = 10), localized bowel wall thickening (n = 7) closed loops obstruction (n = 3) and strangulation (n = 1). The obstruction site was identified in all cases. The causes of obstruction could be diagnosed preoperatively in 14 cases, but a preoperative diagnosis was difficult in 5 cases. The causes of small bowel obstruction in children are variable, and CT is useful for evaluating the cause and localization of small bowel obstruction.

    CT is often used in the diagnosis and management of small-bowel obstruction in children. To determine sensitivity of CT in delineating presence, site and cause of small-bowel obstruction in children. We retrospectively reviewed the CT scans of 47 children with surgically proven small-bowel obstruction. We noted any findings of obstruction and the site and cause of obstruction. Presence, absence or equivocal findings of bowel obstruction on abdominal radiographs performed prior to CT were also noted. We reviewed patient charts for clinical details and surgical findings, including bowel resection. Statistical analysis was performed using Fisher exact test to determine which CT findings might predict bowel resection. CT correctly diagnosed small-bowel obstruction in 43/47 (91.5%) cases. CT correctly indicated site of obstruction in 37/47 (78.7%) cases and cause of obstruction in 32/47 (68.1%) cases. Small-bowel feces sign was significantly associated with bowel resection at surgery (P = 0.0091). No other CT finding was predictive of bowel resection. Out of 41 children who had abdominal radiographs before CT, 29 (70.7%) showed unequivocal obstruction, six (14.6%) showed equivocal findings and six (14.6%) were unremarkable. CT is highly sensitive in diagnosing small-bowel obstruction in children and is helpful in determining the presence of small-bowel obstruction in many clinically suspected cases with equivocal or normal plain radiographs. CT also helps to determine the site and cause of the obstruction with good sensitivity. (orig.)

CT correctly indicated site of obstruction in 37/47 (78.7%) cases and cause of obstruction in 32/47 (68.1%) cases. Small-bowel feces sign was significantly associated with bowel resection at surgery (P = 0.0091). No other CT finding was predictive of bowel resection. Out of 41 children who had abdominal radiographs before CT, 29 (70.7%) showed unequivocal obstruction, six (14.6%) showed equivocal findings and six (14.6%) were unremarkable. CT is highly sensitive in diagnosing small-bowel obstruction in children and is helpful in determining the presence of small-bowel obstruction in many clinically suspected cases with equivocal or normal plain radiographs. CT also helps to determine the site and cause of the obstruction with good sensitivity. (orig.)

    Full Text Available Diverticular disease of the sigmoid colon involves more than 50% of population over 60 years, and much more in people older than 80 years. Most patients remain asymptomatic, but, about 10-20% develop complications requiring surgery. Colonic diverticulitis represents an acute bowel inflammation, in many cases, confined only to the sigmoid and descending colon. Recurrent attacks and complications of diverticulitis require surgical procedure, although most cases can be managed medically. The cause of acute diverticulitis remains obscure. It has been speculated that obstruction at the mouth of the diverticulum results in diverticulitis, similar to appendicitis, but this is no longer the accepted theory, and some feel that chronic inflammation precedes clinical diverticulitis. .

  8. Changing incidence of diverticular disease of the colon in the Koreans: a radiological study

    International Nuclear Information System (INIS)

    Diverticular disease of the colon is the commonest pathological process in the large bowel in the aged caucasians, but this is rare in oriental races.In Korea, diverticular disease of the colon was known to be rare as reported by Kim in 1964. Since then, however, we have had an impression that the diverticular disease of the colon is not so rare as was reported by Kim previously from our department. The present study has been undertaken to substantiate our impression. We received 1,143 consecutive cases of double-contrast barium performed at the Department of radiology, St. Mary's Hospital, Catholic Medical College during the past 7 years to analyzed diverticular disease patterns of the colon in the Koreans. 1. The present study revealed 29 patients of diverticular disease of the colon, an incidence of 2.5%. The age distribution was shown in Table 1. 2. The mean number of diverticular were 9 and the mean size as follows: the cecum, 6.4 mm; the proximal 1/3 of the ascending colon, 5.6 mm, The mid 1/3 of ascending colon, 4.9 mm; and the distal 1/3 of the ascending colon, 4.4 mm. 3. The average age of patients with diverticular disease of the colon was 49.5 years. Chief complaints were change of bowel habit (31.6%), abdominal pain (28.9%) and indigestion (18.4%). 4. The associated radiological findings of diverticular disease of the colon were: (1) spasm in 16 cases (46%); (2) a marginal irregularity in 16 cases (25%); and (3) asymmetrical haustra in 16 cases (30%). In 13 cases no associated signs seen. We have found that incidence of the diverticular disease of the colon in the present series is very significantly higher than that of the previous report from our department (Kim, 1964). We postulate that the possible factors operational in such increase in the incidence of the clonic diverticular disease in the last decade are: (1) changing dietary pattern characterized by high-protein and high refined-sugar consumption, and (2) routine use of the double contrast technique which permitted us to see more diverticular outpouchings of the colon compared to the conventional simple barium enema study.

  9. The effect of barium infusion rate on the diagnostic value of small bowel enteroclysis

    International Nuclear Information System (INIS)

    Although enteroclysis may have many advantages over the conventional methods of small bowel examination, the contrast material is not always infused at a rate appropriate to gain maximum diagnostic information. In this study, 190 patients were examined by small bowell enteroclysis at five contrast infusion rates ranging from 50 to 150 ml/min using a newly designed infusion pump system. The results show that at rates above 75 ml/min, motility disturbances are masked by small bowel dilatation and paralysis, transit times are extended and morphological detail is obscured. At rates below 75 ml/min, incomplete filling of the loops renders optimal diagnostic evaluation impossible. An infusion rate of 75 ml/min was found to be optimal for initiating small bowel studies. This rate can be adjusted for individual cases when pathology or drugs affect the motility of the small bowel. 13 refs.; 5 figs.; 1 table

    Gossypiboma, an infrequent surgical complication, is a mass lesion due to a retained surgical sponge surrounded by foreign body reaction. In this case report, we describe gossypiboma in the abdominal cavity which was detected 14 months after the hysterectomy due to acute abdominal pain. Gossypiboma was diagnosed by computed tomography (CT). The CT findings were a rounded mass with a dense central part and an enhancing wall. In explorative laparotomy, small bowel loops were seen to be perforated due to inflammation of long standing gossypiboma. Jejunal resection with end-to-end anastomosis was performed. The patient was discharged whithout complication. This case was presented to point to retained foreign body (RFB) complications and we believed that the possibility of a retained foreign body should be considered in the differential diagnosis of who had previous surgery and complained of pain, infection, or palpable mass.

    Full Text Available Abstract Background The term "gossypiboma" denotes a mass of cotton that is retained in the body following surgery. Gossypiboma is a medico-legal problem especially for surgeons. To the best of our knowledge, the patient presented herein is the second reported patient in whom the exact site of migration of a retained surgical textile material into the intestinal lumen could be demonstrated by preoperative imaging studies. Case presentation A 74-year-old woman presented with symptoms of small bowel obstruction due to incomplete intraluminal migration of a laparotomy towel 3 years after open cholecystectomy and umbilical hernia repair. Plain abdominal radiography did not show any sign of a radio-opaque marker in the abdomen. However, contrast enhanced abdominal computerized tomography revealed a round, well-defined soft-tissue mass with a dense, enhanced wall, containing an internal high-density area with air-bubbles in the mid-abdomen. A fistula between the abscess cavity containing the suspicious mass and gastrointestinal tract was identified by upper gastrointestinal series. The presence of a foreign body was considered. It was surgically removed with a partial small bowel resection followed by anastomosis. Conclusions Although gossypiboma is rarely seen in daily clinical practice, it should be considered in the differential diagnosis of acute mechanical intestinal obstruction in patients who underwent laparotomy previously. The best approach in the prevention of this condition can be achieved by meticulous count of surgical materials in addition to thorough exploration of surgical site at the conclusion of operations and also by routine use of surgical textile materials impregnated with a radio-opaque marker.

  12. Scintigraphic diagnosis of inflammatory small bowel stenoses in Crohn's disease using 111In-labelled leucocytes

    International Nuclear Information System (INIS)

    17 patients with known small bowel involvement in Crohn's disease (clinically active, n=14; clinically inactive, n=3) were examined within 8 days via barium enemas of the small bowel (Pansdorf's method or enteroclysma) and by 111In-oxin labelled leucocytes. From 19 radiologically diagnosed small bowel stenoses 14 were classified as inflammatory and 5 as non-inflammatory. The leucocyte scan also showed 14 inflammatory stenoses. The not inflamed stenoses could not be diagnosed scintigraphically. The barium enemas of the small bowel and the leukocyte scans both correctly diagnosed the acute inflamed segments. The inability to show non-inflamed segments (n=5) and to localise small bowel stenoses exactly is disadvantageous in the scan. The advantage of the leucocyte scan is a non invasive examination without specific bowel preparation and the possibility to diagnose additionally inflamed large bowel segments (n=4), fistulas and abscesses (n=2). The leucocyte scan offers a useful expansion of the diagnostic tools in small bowel diseases, especially in radiological problems in patients with Crohn's disease. (orig.)

    This article describes the recent advances in radiological imaging of malignant neoplasms of the mesenteric small bowel and provides an outline of new trends and perspectives that can be anticipated. The introduction of multidetector row technology, which allows the acquisition of submillimeter and isotropic voxels, has dramatically improved the capabilities of computed tomography in the investigation of the mesenteric small bowel. This technology combined with optimal filling of small bowel loops through the use of appropriate enteral contrast agents has markedly changed small bowel imaging. Computed tomography-enteroclysis, which is based on direct infusion of enteral contrast agent into the mesenteric small bowel through a naso-jejunal tube, provides optimal luminal distension. By contrast, computed tomography-enterography is based on oral administration of enteral contrast agent. These two techniques are now well-established ones for the detection and the characterization of small bowel neoplasms. During the same time, combining the advantages of unsurpassed soft tissue contrast and lack of ionizing radiation, magnetic resonance imaging has gained wide acceptance for the evaluation of patients with suspected small bowel neoplasms. Rapid magnetic resonance imaging sequences used in combination with specific enteral contrast agents generate superb images of the mesenteric small bowel so that magnetic resonance-enteroclysis and magnetic resonance-enterography are now considered as effective diagnostic tools for both the detection and the characterization of neoplasms of the mesenteric small bowel. Recent improvements in image post-processing capabilities help obtain realistic three-dimensional representations of tumors and virtual enteroscopic views of the small bowel that are useful for the surgeon and the gastroenteroenteologist to plan surgical or endoscopic interventions. Along with a better knowledge of the potential and limitations of wireless capsule endoscopy and new endoscopic techniques, these recent developments in radiological imaging reasonably suggest that substantial changes in the investigation of small bowel tumors may be anticipated in a near future, thus potentially create a new paradigm shift after standard small bowel follow-through study has been universally abandoned.

    2012-01-01

    Full Text Available A 40-year-old male, diagnosed with mild Crohn’s disease (CD 11 years ago but with no prior abdominal surgeries, was diagnosed with a small bowel stricture, due to ongoing abdominal pain and intolerance of enteral diet, and referred for surgical treatment. Exploratory laparoscopy revealed a white solid mass causing a near total jejunal obstruction with significant proximal dilatation. An adjacent small node was sampled for frozen biopsy, revealing a lymph node infiltrated with adenocarcinoma. Laparoscopic assisted small bowel resection and appendectomy were carried out. Final pathological results supported the initial report of diffuse small bowel adenocarcinoma. In conclusion, once a small bowel stricture associated with CD is suspected, rapid action should be considered to avoid late diagnosis of a neoplasia.

    Crohn's disease (CD) is a chronic relapsing inflammatory disease of the gastrointestinal tract, which mostly affects young patients. Imaging techniques form a very important part for the evaluation of CD and for monitoring disease progression or response to therapy. Currently, imaging of CD is increasingly being performed by cross-sectional modalities, i.e. multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI), since these techniques allow for simultaneous visualization of luminal, mural and extraintestinal disease extension. MR enterography has the potential to safely and noninvasively accomplish the imaging needs of patients with Crohn disease without exposing them to ionizing radiation. The new imaging paradigm should contemplate patient safety as a very important aspect when assessing the role of an imaging modality in comparison with others. For this reason, MRI may be the preferred modality for evaluation of small bowel disease, especially in young patients in the setting of CD, considering that the majority will undergo frequent repeat studies. Also, the information on disease activity is not matched by any other imaging method. In this review article, the authors discuss the essential aspects of MR evaluation of CD, including protocol and imaging findings, also referring the advantages over other radiological studies, concerning safety, accuracy and potential importance for therapeutic approach.

    Full Text Available AIM: To determine if a nasojejunal tube (NJT is required for optimal examination of enteroclysis and if patients can be examined only in the supine position.METHODS: Data were collected from all patients undergoing small bowel (SB magnetic resonance imaging (MRI examination over a 32-mo period. Patients either underwent a magnetic resonance (MR follow-through (MRFT or a MR enteroclysis (MRE in the supine position. The quality of proximal and distal SB distension as well as the presence of motion artefact and image quality were assessed by 2 radiologists.RESULTS: One hundred and fourteen MR studies were undertaken (MRFT-49, MRE-65 in 108 patients in the supine position only. Image artefact was more frequent in MRE than in MRFT (29.2% vs 18.4%, but was not statistically significant (P = 0.30. Adequate distension of the distal SB was obtained in 97.8% of MRFT examinations and in 95.4% of MRE examinations, respectively. Proximal SB distension was, however, less frequently optimal in MRFT than in MRE (P = 0.0036, particularly in patients over the age of 50 years (P = 0.0099. Image quality was good in all examinations.CONCLUSION: All patients could be successfully imaged in the supine position. MRE and MRFT are equivalent for distal SB distension and artefact effects. Proximal SB distension is frequently less optimal in MRFT than in MRE. MRE is, therefore, the preferred MR examination method of the SB.

    Examinations using ionizing radiation are frequently used in the evaluation of disease activity in children affected by idiopathic inflammatory bowel disease (IBD). To develop an MR imaging protocol without the need for fluoroscopic insertion of an enteral tube and to assess the disease activity in children with IBD. Included in the study were 37 children (22 girls and 15 boys; age range 7-15 years, mean 11.67 years) with IBD who underwent MR imaging of the small bowel. Of these 37 children, 32 had Crohn disease and 5 had indeterminate colitis. A water solution containing herbal fibres was administered orally or through a nasogastric tube. Patients were imaged on a 1.5-T MR scanner with T1-weighted and {tau}2-weighted sequences followed by a dynamic study using 3-D T1-W images after intravenous administration of gadolinium. The percentage enhancement of the bowel wall was significantly increased in patients with abnormal C-reactive protein (CRP) values compared to patients with CRP values in the normal range (P<0.001). A relatively weak but significant correlation between percentage enhancement of the bowel wall and CRP values was noted during all phases of enhancement. This MR imaging protocol is a safe and well-tolerated method for evaluating disease activity and extraintestinal manifestations of IBD in children. (orig.)

  18. Ultrasound in Crohn's disease of the small bowel

    International Nuclear Information System (INIS)

    Objective: The purpose of this work is to prospectively evaluate high resolution ultrasonography with graded compression in the ability to detect Crohn's disease of the small bowel (CDSB) together with its complications and activity signs, compared with enteroclysis, CT and immunoscintigraphy in the mirror of the final diagnosis. Methods and material: In a series of 73 consecutive patients, who were referred for enteroclysis with suspected Crohn's disease of the small bowel computed tomography (CT), ultrasound (US), immunoscintigraphy with 99mTc labeled monoclonal antigranulocyte antibody (AGAb) examinations were performed within 10 days from each other. For the final evaluation the diagnosis of CDSB was based on combination of clinical and enteroclysis findings (73 cases) and in 17 cases additional surgical and pathological data were available. The results of other modalities were blinded to the radiologists performing and reading out the exams. The diagnostic values of each modality was assessed also in those 18 patients, who had early Crohn's disease. In the group of 43 patients with proven CDSB who had all the four imaging modalities, the modalities were compared in their ability to demonstrate various pathological conditions related to CD. Increased (>500 ml/min) flow measured by Doppler US in the superior mesenteric artery and increased color signs in the gut wall seen by power Doppler sonography were compared to CDAI. Results: Of the 73 patients the combination of enteroclysis and clinical tests demonstrated CDSB in 47. The sensitivity, specificity and accuracy of ultrasound were 88.4, 93.3 and 90.4%, respectively. Enteroclysis was the most accurate method. CT was more sensitive than US, but less specific. The accuracy of US, CT and scintigraphy were similar. In the group of 18 patients, who had early CDSB, the sensitivity of US decreased to only 67%, CT and scintigraphy had higher values. Intra- and perimural abscesses, and sinus tracts were also more frequently visualized by US, especially if they were small. US was superior than CT in detecting stenoses and skip lesions, but inferior to enteroclysis. US and CT detected more fistulas, than enteroclysis. Compared to CT, US detected more cases with mesenteric lymphadenopathy, equal cases with abscesses and free peritoneal fluids. In detecting mesenteric inflammatory proliferation CT, and in detecting colonic involvement CT and immunoscintigraphy were slightly superior than graded compression US. Patterns of mural stratification detected by ultrasound correlated well with the enteroclysis severity stages. There was only 59% agreement between increased superior mesenteric artery flow detected by Doppler sonography and CDAI, and 60.5% agreement between increased number of Color pixels in the gut wall measured by power Doppler and increased CDAI. Conclusion: High resolution graded compression sonography is a valuable tool for detecting small intestinal Crohn's disease. It has similar diagnostic values as CT. However in early disease the sensitivity substantially decreases. In known Crohn's disease for following disease course, evaluating relapses and extramural manifestations US is an excellent tool. Doppler and Power Doppler activity measurements do not correlate well with the more widespread clinical activity index

  20. The effect of obesity levels on irradiated small bowel volume in belly board with small bowel displacement device for rectal cancer radiotherapy

    International Nuclear Information System (INIS)

    For radiotherapy in rectal cancer patients treated with small bowel displacement device (SBDD) and belly board, We will suggest new indication of using SBDD depending on obesity index by analyzing correlation between obesity and irradiated small bowel volume. In this study, We reviewed 29 rectal cancer patients who received pelvic radiation therapy with belly board and SBDD from January to April in 2012. We only analyzed those patients treated with three-field technique (PA and both LAT) on 45 Gy (1.8 Gy/fx). We measured patients' height, weight, body mass index (BMI), waist-hip ratio (WHR) and divided BMI into two groups.(?23:BMI=group 1, <23:BMI=group 2) We performed a statistical analysis to evaluate correlation between total volume of bladder (TVbldder), obesity index and high dose volume of small bowel (small bowel volume irradiated at 90% of prescribed dose, HDVsb), low dose volume of small bowel (small bowel volume irradiated at 33% of prescribed dose, LDVsb). The result shows, gender, WHR and status of pre operative or post operative do not greatly affect HDVsb and LDVsb. Statistical result shows, there are significant correlation between HDVsb and BMI (p<0.04), HDVsb and TVbladder (p<0.01), LDVsb and TVbladder (p<0.01). BMI seems to correlate with HDVsb but does not with LDVsb (p>0.05). There are negative correlation between HDVsb and BMI, TVbladder and HDVsb, TVbladder and LDVsb . Especially, BMI group1 has more effective and negative correlation with HDVsb (p=0.027) than in BMI group 2. In the case of BMI group 1, TVbladder has significant negative correlation with HDVsb and LDVsb (p<0.04). In conclusions, we confirmed that Using SBDD with belly board in BMI group 1 could more effectively reduce irradiated small bowel volume in radiation therapy for rectal cancer. Therefore, We suggest using belly board with SBDD in order to reduce the small bowel toxicity in rectal radiotherapy, if patients' BMI is above 23

    Conclusion: The case presented highlights the difficulty in making the diagnosis, and the pictures clearly indicate an unusual hernia passing directly behind the stomach and involving a large section of the small bowel. The lead up history of several admissions with sub acute small bowel obstruction suggested the underlying problem was adhesional but quite clearly there was a well defined internal hernia. Without timely surgery she would have been at high risk of losing her pouch.

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

    Before an enteropathogen binds to the small bowel, it must interact with the small-bowel mucus (SBM) layer. To determine whether this interaction involves specific binding of diarrheagenic Escherichia coli, we used a quantitative assay with labeled, purified rabbit SBM. Binding of SBM from an adult rabbit was significantly greater to strain 162, an agglutinating E. coli strain, than it was to RDEC-1, a rabbit pathogen, and was significantly greater to strain 2348/PMAR, an enteropathogenic E. ...

    2009-04-01

    Full Text Available Abstract Small bowel contractility may be more prominent in obese subjects, such that there is enhanced nutrient absorption and hunger stimulation. However, there is little evidence to support this. This study examined in vitro small bowel contractility in obese patients versus non-obese patients. Samples of histologically normal small bowel were obtained at laparoscopic Roux-en-Y gastric bypass from obese patients. Control specimens were taken from non-obese patients undergoing small bowel resection for benign disease or formation of an ileal pouch-anal anastamosis. Samples were transported in a pre-oxygenated Krebs solution. Microdissected circular smooth muscle strips were suspended under 1 g of tension in organ baths containing Krebs solution oxygenated with 95% O2/5% CO2 at 37°C. Contractile activity was recorded using isometric transducers at baseline and in response to receptor-mediated contractility using prostaglandin F2a, a nitric oxide donor and substance P under both equivocal and non-adreneregic, non-cholinergic conditions (guanethidine and atropine. Following equilibration, the initial response to the cholinergic agonist carbachol (0.1 mmol/L was significantly increased in the obese group (n = 63 versus the lean group (n = 61 with a mean maximum response: weight ratio of 4.58 ± 0.89 vs 3.53 ± 0.74; (p = 0.032. Following washout and re-calibration, cumulative application of substance P and prostaglandin F2a produced concentration-dependent contractions of human small bowel smooth muscle strips. Contractile responses of obese small bowel under equivocal conditions were significantly increased compared with non-obese small bowel (p Stimulated human small bowel contractility is increased in obese patients suggesting faster enteric emptying and more rapid intestinal transit. This may translate into enhanced appetite and reduced satiety.

    Ascariasis is one of the most common helminthic disease worldwide and evoked variable clinical manifestations by the migration of worm in the alimentary and biliary tract. The ultrasonographic detection of ascaris in the small bowel is relatively difficult, and no report on the ultrasonographic findings have been published in Korea. On abdominal ultrasonography, ascaris is seen as an intraluminal tubular structure with 4 linear echogenic stripes and movement. We report a case of ascaris in the small bowel detected by abdominal ultrasonography.

    2014-01-01

    Capsule endoscopy (CE) has a high sensitivity for diagnosing small bowel Crohn's disease, but video analysis is time consuming. The quick view (qv) function is an effective tool to reduce time consumption. The aim of this study was to determine the rate of missed small bowel ulcerations with qv-CE compared to standard view and the diagnostic accuracy of qv-CE in suspected Crohn's disease.

    Background. Small bowel peristalsis is a complex of many individual motion elements. Although each element of peristalsis can be measured there is no current global measure of peristalsis. Purpose. To examine the feasibility of automated computerized assessment of global small bowel motility using simple computational methods. Material and Methods. Coronal dynamic MR images were obtained from five healthy volunteers who had fasted for 9 h and drunk 1.5 L of water. Images were taken using single breath-hold and ECG triggering. Acquisitions were repeated at 10 and 20 min after an intramuscular injection of hyoscine butylbromide. Parametric maps were generated representing the mean change in signal amplitude (MSA) per voxel for each dynamic acquisition. Two observers independently assessed thresholding for optimal segmentation of small bowel from other sources of signal. Total voxel activity (TVA) for each study was calculated as a sum of MSA per slice and whole examination and TVA profiles were generated. Results. Independent observations suggest that the automated segmentation method described usefully segments small bowel activity from other signal. Small bowel movement represented as TVA varied three-fold in the five volunteers and was inhibited by anti-muscarinic injection. Conclusion. It is possible to develop a new measure, based on automated segmentation of mean signal amplitude changes, of small bowel peristalsis using dynamic MR.

    To identify CT findings predictive of surgical management in non-emergency small bowel obstruction (SBO). Contrast-enhanced abdominal CT of 129 patients with non-emergency SBO were evaluated for small bowel luminal diameter, wall thickness, presence of the small bowel faeces sign (intraluminal particulate matter in a dilated small bowel) and length, transition point, submucosal oedema, mesenteric stranding, ascites and degree of obstruction (low grade partial, high grade partial and complete obstruction). Medical records were reviewed for age, gender, management and history of abdominal surgery, abdominal malignancy, or SBO. Statistical analyses were performed with Stata Release 9.2. Degree of obstruction was the only predictor of need for surgery. Whereas 18.0% of patients with low-grade partial obstruction (n = 50) underwent surgery, 32.5% of patients with high-grade partial obstruction (n = 77) and 100% of patients with complete obstruction (n = 2) required surgery (P = 0.004). The small bowel faeces sign was inversely predictive of surgery (P = 0.018). In non-emergency SBO patients with contrast-enhanced CT imaging, grade of obstruction predicts surgery, while the small bowel faeces sign inversely predicts need for surgery. (orig.)

    Full Text Available Small bowel metastasis from primary bone leiomyosarcoma is very rare. Here we reporton a 50-year-old man who presented with general weakness, weight loss (six kg in twomonths and intermittent tarry stools for two months. He had undergone an above-kneeamputation for left tibia leiomyosarcoma seven years previously. No local recurrence and/ordistant metastasis developed during a seven-year period of follow-up. Subsequent imagingstudy revealed a multilobulated mass in the ileum. He received segmental resection of thesmall bowel and a multilobulated mass was noted in the submucosal layer of the ileum withmucosa ulceration. His postoperative course was uneventful. Histopathological examinationof the resected mass revealed small bowel metastatic leiomyosarcoma. No local recurrenceor distant metastases were detected during a six-month follow-up period. To the best of ourknowledge, this is the first report of small bowel metastasis from primary bone leiomyosarcomapresenting with lower gastrointestinal bleeding.

    2015-09-28

    Small-bowel carcinoid tumors are the most common form (42%) of gastrointestinal carcinoids, which by themselves comprise 70% of neuroendocrine tumors. Although primary small bowel neoplasms are overall rare (3%-6% of all gastrointestinal neoplasms), carcinoids still represent the second most common (20%-30%) primary small-bowel malignancy after small bowel adenocarcinoma. Their imaging evaluation is often challenging. State-of-the-art high-resolution multiphasic computed tomography together with advanced postprocessing methods provides an excellent tool for their depiction. The manifold interactive parameter choices however require knowledge of when to use which technique. Here, we discuss the imaging appearance and evaluation of duodenal, jejunal and ileal carcinoid tumors, including the imaging features of the primary tumor, locoregional mesenteric nodal metastases, and distant metastatic disease. A protocol for optimal lesion detection is presented, including the use of computed tomography enterography, volume acquisition, computed tomography angiography and three-dimensional mapping. Imaging findings are illustrated with a series of challenging cases which illustrate the spectrum of possible disease in the small bowel and mesentery, the range of possible appearances in the bowel itself on multiphase data and extraluminal findings such as the desmoplastic reaction in mesentery and hypervascular liver metastases. Typical imaging pitfalls and pearls are illustrated. PMID:26435774

  18. Small bowel obstruction in percutaneous fixation of traumatic pelvic fractures

    2013-01-01

    Full Text Available The use of external fixation for the initial treatment of unstable, complex pelvic injuries with hemodynamic instability remains an effective treatment for multiply injured patients. Bowel entrapment within a pelvic fracture is a rarely reported, potentially fatal complication. Here, we report a polytrauma patient with pelvic fractures who developed an intestinal obstruction after an external fixation. At an explorative laparotomy, we found an ileum segment trapped in the sacral fracture. Reported cases of bowel entrapment in pelvic fractures, especially in sacral fractures, are exceedingly rare. The diagnosis is often delayed due to difficulty distinguishing entrapment from the more common adynamic ileus. In conclusion, clinicians and radiologists should be aware of this potentially lethal complication of pelvic fractures treatment. To exclude bowel entrapment, patients with persistent ileus or sepsis should undergo early investigations.

    Full Text Available Temsirolimus has been demonstrated to result in significant disease stabilization in children with high-grade glioma, neuroblastoma, and rhabdomyosarcoma. While mucositis has been reported as a common adverse effect of temsirolimus therapy in adult and pediatric patients, bowel perforation is an infrequent and life-threatening side effect of temsirolimus in adults and has not previously been reported in children. We present a child treated with temsirolimus for recurrent metastatic rhabdomyosarcoma who underwent ileocecectomy and small bowel resection for perforation with frank necrosis. His presentation was complicated by Clostridium septicum infection, a rare, frequently fatal, gastrointestinal pathogen associated with malignancy and bowel ischemia.

  20. Cine Magnetic Resonance Imaging of the Small Bowel: Comparison of Different Oral Contrast Media

    International Nuclear Information System (INIS)

    Purpose: To evaluate several substances regarding small bowel distension and contrast on balanced steady-state free precession (bSSFP) cine magnetic resonance (MR) images. Material and Methods: Luminal contrast was evaluated in 24 volunteers after oral application of two different contrast agent groups leading to either bright lumen (pineapple, blueberry juice) or dark lumen (tap water, orange juice) on T1-weighted images. Bowel distension was evaluated in 30 patients ingesting either methylcellulose or mannitol solution for limiting intestinal absorption. Fifteen patients with duodeno-jejunal intubation served as the control. Quantitative evaluation included measurement of luminal signal intensities and diameters of four bowel segments, qualitative evaluation assessed luminal contrast and distension on a five-point scale. Results: Quantitative and qualitative evaluation of the four contrast agents revealed no significant differences regarding luminal contrast on bSSFP images. Quantitative evaluation revealed significantly lower (P<0.05) small bowel distension for three out of four segments (qualitative evaluation: two out of four segments) for methylcellulose in comparison to the control. Mannitol was found to be equal to the control. Conclusion: Oral ingestion of tap water or orange juice in combination with mannitol is recommended for cine MR imaging of the small bowel regarding luminal contrast and small bowel distension on bSSFP sequences

  4. Online adaptive radiotherapy of the bladder: Small bowel irradiated-volume reduction

    International Nuclear Information System (INIS)

    Purpose: To assess the potential reduction of small bowel volume receiving high-dose radiation by using kilovoltage X-ray cone beam computed tomography (CBCT) and quantized margin selection for adaptive bladder cancer treatment. Methods and Materials: Twenty bladder patients were planned conformally using a four-field, 15-mm uniform margin technique. Two additional planning target volumes (PTVs) were created using margins quantized to 5 and 10 mm in the superior direction only. CBCTs (?8 scans/patient) were acquired during treatment. CBCT volumes were registered with CT planning scans to determine setup errors and to select the appropriate PTV of the day. Margin reduction in other directions was considered. Outlining of small bowel in every fraction is required to properly quantify the volume of small bowel spared from high doses. In the case of CBCT this is not always possible owing to artifacts created by small bowel movement and the presence of gas. A simpler method was adopted by considering the volume difference between PTVs created using uniform and adapted margins, which corresponds to the potential volume of small bowel sparing. Results: The average small bowel volume that can be spared by this form of adaptive radiotherapy is 31 ± 23 cm3 (±1 SD). The bladder for 1 patient was systematically smaller than the planning scan and hence demonstrated the largest average reduction of 76 cm3. The clinical target volume to PTV margins in other directions can be safely reduced to 10 mm except in the anterior direction where, like the superior direction, the bladder showed significant variation. Conclusions: Online CBCT-assisted plan selection based on quantized margins can significantly reduce the volume of small bowel receiving high doses for some bladder patients. CBCT allows the 15-mm margins used in some directions to be safely reduced to 10 mm

    2009-08-15

    This study aims to determine inter- and intra-observer variation in MRI measurements of relative bowel wall signal intensity (SI) in Crohn's disease. Twenty-one small bowel MRI examinations (11 male, mean age 40), including T1-weighted acquisitions acquired 30 to 120s post-gadolinium, were analysed. Maximal bowel wall SI (most avid, conspicuous contrast enhancement) in designated diseased segments was measured by two radiologists and two trainees using self-positioned ''free'' regions of interest (ROIs) followed by ''fixed'' ROIs chosen by one radiologist, and this procedure was repeated 1 month later. Relative enhancement (post-contrast SI minus pre-contrast SI/pre-contrast SI) was calculated. Data were analysed using Bland-Altman limits of agreement and intra-class correlation. Inter-observer agreement for relative enhancement was poor (spanning over 120%) using a free ROI - 95% limits of agreement -0.69, 0.70 and -0.47, 0.74 for radiologists and trainees, respectively, only marginally improved by use of a fixed ROI -0.60, 0.67 and -0.59, 0.49. Intra-class correlation ranged from 0.46 to 0.72. Intra-observer agreement was slightly better and optimised using a fixed ROI - 95% limits of agreement -0.52, 0.50 and -0.34, 0.28 for radiologists and trainees, respectively. Intra-class correlation ranged from 0.49 to 0.86. Relative bowel wall signal intensity measurements demonstrate wide limits of observer agreement, unrelated to reader experience but improved using fixed ROIs. (orig.)

  6. Spectrum of imaging findings on MDCT enterography in patients with small bowel tuberculosis

    International Nuclear Information System (INIS)

    Abdominal tuberculosis (TB) is the sixth most common extrapulmonary site of involvement. The sites of involvement in abdominal tuberculosis, in descending order of frequency, are lymph nodes, genitourinary tract, peritoneal cavity, and gastrointestinal tract. The radiological armamentarium for evaluating tuberculosis of the small bowel (SBTB) includes barium studies (small bowel follow-through, SBFT), CT (multidetector CT, CT enterography, and CT enteroclysis), ultrasound (sonoenteroclysis), and magnetic resonance imaging (MRI; enterography and enteroclysis). In this review, we illustrate the abnormalities at MDCT enterography in 20 consecutive patients with SB TB and also describe extraluminal findings in these patients. MDCT enterography allows non-invasive good-quality assessment of well-distended bowel loops and the adjacent soft tissues. It displays the thickness and enhancement of the entire bowel wall in all three planes and allows examination of all bowel loops, especially the ileal loops, which are mostly superimposed. The terminal ileum and ileocaecal junction are the most common sites of small bowel involvement in intestinal TB. The most common abnormality is short-segment strictures with symmetrical concentric mural thickening and homogeneous mural enhancement. Other findings include lymphadenopathy, ascites, enteroliths, peritoneal thickening, and enhancement. In conclusion, MDCT enterography is a comprehensive technique for the evaluation of SB TB

  7. Lymphangioma of the small bowel mesentery: A case report and review of the literature

    Directory of Open Access Journals (Sweden)

    Worapop Suthiwartnarueput

    2012-01-01

    Full Text Available Lymphangioma is a rare benign condition characterized by proliferation of lymphatic spaces. It is usually found in the head and neck of affected children. Lymphangioma of the small-bowel mesentery is rare, having been reported for less than 1% of all lymphangiomas. Importantly, it can cause fatal complications such as volvulus or involvement of the main branch of the mesenteric arteries, requiring emergency surgery. Moreover, the gross and histopathologic findings may resemble benign multicystic mesothelioma and lymphangiomyoma. Immunohistochemical study for factor VIII-related antigen, D2-40, calretinin and human melanoma black-45 (HMB-45 are essential for diagnosis. Factor VIII-related antigen and D2-40 are positive in lymphangioma but negative in benign multicystic mesothelioma. HMB-45 shows positive study in the smooth-muscle cells around the lymphatic spaces of the lymphangiomyoma. We report a case of small-bowel volvulus induced by mesenteric lymphangioma in a 2-year-and-9-mo-old boy who presented with rapid abdominal distension and vomiting. The abdominal computed tomography scan showed a multiseptated mass at the right lower quadrant with a whirl-like small-bowel dilatation, suggestive of a mesenteric cyst with midgut volvulus. The intraoperative findings revealed a huge, lobulated, yellowish pink, cystic mass measuring 20 cm × 20 cm × 10 cm, that was originated from the small bowel mesentery with small-bowel volvulus and small-bowel dilatation. Cut surface of the mass revealed multicystic spaces containing a milky white fluid. The patient underwent tumor removal with small-bowel resection and end-to-end anastomosis. Microscopic examination revealed that the cystic walls were lined with flat endothelial cells and comprised of smooth muscle in the walls. The flat endothelial cells were positive for factor VIII-related antigen and D2-40 but negative for calretinin. HMB-45 showed negative study in the smooth-muscle cells around the lymphatic spaces. Thus, the diagnosis was lymphangioma of the small bowel mesentery with associated small bowel volvulus.

  8. X-ray findings of small bowel taeniasis: A clinical and experimental study

    International Nuclear Information System (INIS)

    Unlike ascariasis of the small bowel, taeniasis can be detected radiologically with much difficulty because of the basic difference between the morphological features of each helminth. However once the characteristics of tape worms are appreciated and kept in mind, radiological diagnosis is fairly accurately made. In the present study we have reported typical radiological features of the small bowel taeniasis as observed in 6 adults patients seen at the Department of Radiology of St. Mary's Hospital and Holy Family Hospital, Catholic Medical College. Tapering tape-like or ribbon -like radiolucent shadows in distal small bowel appear unique. Compression spot film study of the ileum is most important in revealing such findings. An animal experiment using the swine small intestine and parasitological specimen of evacuated worm of taenia saginata was designed to help understand radiological manifestation in vivo

    Small bowel diverticulitis is a rare cause of an acute abdomen. Originating from acquired diverticula of the jejunum, less often of the ileum, or Meckel diverticulum, the symptoms are non-specific, simulating other acute inflammatory disorders, such as appendicitis, cholecystitis or colonic diverticulitis. The diagnosis of small bowel diverticulitis is solely based on radiologic findings, with computed tomography (CT) regarded as the method of choice. In recent years, a number of case reports have described the spectrum of the CT features in acute small bowel diverticulitis and its dependence on the severity of the inflammatory process. Typical findings are an inflamed diverticulum, inflammatory mesenteric infiltration, extraluminal gas collection and mural edema of adjacent small bowel loops with resultant separation of bowel loops. An enterolith is rarely found in an inflamed diverticulum. Complications include abscesses, fistulae, small bowel obstruction and free perforation with peritonitis. Small bowel diverticulitis can be a diagnostic problem if it involves the terminal ileum or Meckel's diverticulum. For preoperative confirmation of the presumed diagnosis of small bowel diverticulitis on CT, an enteroclysis for acquired diverticula or a technetium scan for Meckel's diverticulum should be performed. We present the CT findings in three patients of acute small bowel diverticulitis, two affecting the jejunum and one a Meckel's diverticulum. (orig.) [German] Die akute Duenndarmdivertikulitis ist eine seltene Ursache eines akuten Abdomens. Ausgehend von den erworbenen Divertikeln des Jejunums, seltener des Ileums, oder von einem Meckel-Divertikel, manifestiert sich die Divertikulitis klinisch durch eine unspezifische Symptomatik, die zuerst an die haeufigeren, akutentzuendlichen Erkrankungen des Abdomens wie z. B. Appendizitis, Cholezystitis oder Kolondivertikulitis denken laesst. Die Duenndarmdivertikulitis kann praeoperativ nur durch radiologische Verfahren gesichert werden, wobei die CT die Methode der Wahl darstellt. Das vorwiegend in Form von Kasuistiken beschriebene Spektrum der CT-Morphologie der akuten Duenndarmdivertikulitis variiert je nach Ausmass des Entzuendungsprozesses. Als typische CT-Befunde finden sich ein entzuendetes Divertikel, peridivertikulaere Fettgewebsinfiltrationen, extraluminale Luftansammlungen als Zeichen einer gedeckten Perforation und ein Wandoedem des betroffenen Duenndarmsegmentes mit vermehrter Distanzierung der Darmschlingen. In sehr seltenen Faellen kann auch ein Enterolith in einem entzuendeten Divertikel nachweisbar sein. An Komplikationen koennen Abszesse, Fisteln, ein Ileus und eine freie Perforation mit Peritonitis auftreten. Diagnostische Probleme bereitet die Duenndarmdivertikulitis von allem bei Lokalisation im terminalen Ileum und im Meckel-Divertikel. Zur Sicherung der computertomographischen Verdachtsdiagnose einer akuten Duenndarmdivertikulitis koennen ein Enteroklysma bzw. beim Meckel-Divertikel eine 99m-Technetium-Pertechnetat-Szintigraphie eingesetzt werden. Wir beschreiben die CT-Befunde zweier Patientinnen mit akuter Jejunumdivertikulitis und eines Patienten mit Meckel-Divertikulitis und vergleichen die Ergebnisse mit den Angaben aus der Literatur.

  12. Ethanol inhibition of glucose absorption in isolated, perfused small bowel of rats

    International Nuclear Information System (INIS)

    There is evidence for both humans and rats that malnutrition frequently occurs when ethanol is chronically ingested. Small bowel 14C-labelled glucose absorption was measured with an ex vivo system in which the small bowel of the rat was surgically removed and then arterially perfused with an artificial medium. Glucose absorption for a control group of seven rats was 248 +/- 8 microM/min/gm dry weight of small bowel (mean +/- SEM). This was significantly greater than the value 112 +/- 12 microM/min/gm dry weight (P less than 0.005) for a group of five rats in which a competitive inhibitor of glucose absorption, phlorizin (0.2 mM), was added to the bowel lumen. In the presence of 3% ethanol within the gut lumen of five rats, glucose absorption was also reduced (to 131 +/- 12 microM/min/gm dry weight) compared to absorption in the control group (P less than 0.005). The calculated amount of glucose absorbed was corrected for metabolism to lactate and carbon dioxide. We conclude that both phlorizin and ethanol inhibit glucose absorption in the isolated and perfused small bowel of rats and that probably at least part of the malnutrition in ethanol-fed rats is due to glucose malabsorption

    Full Text Available AIM: To examine the predictive factors of capsule endoscopy (CE completion rate (CECR including the effect of inpatient and outpatient status. METHODS: We identified 355 consecutive patients who completed CE at Rush University Medical Center between March 2003 and October 2005. Subjects for CE had either nothing by mouth or clear liquids for the afternoon and evening of the day before the procedure. CE exams were reviewed by two physicians who were unaware of the study hypotheses. After retrospective analysis, 21 cases were excluded due to capsule malfunction, prior gastric surgery, endoscopic capsule placement or insufficient data. Of the remaining 334 exams [264 out-patient (OP, 70 in-patient (IP], CE indications, findings, location of the patients [IP vs OP and intensive care unit (ICU vs general medical floor (GMF] and gastrointestinal transit times were analyzed. Statistical analysis was completed using SPSS version 17 (Chicago, IL. Chi-square, t test or fisher exact-tests were used as appropriate. Multivariate logistic regression analysis was used to identify variables associated with incomplete CE exams. RESULTS: The mean age for the entire study population was 54.7 years. Sixty-one percent of the study population was female, and gender was not different between IPs vs OPs (P = 0.07. The overall incomplete CECR was 14% in our study. Overt obscure gastrointestinal bleeding (OGB was significantly more common for the IP CE (P = 0.0001, while abdominal pain and assessment of IBD were more frequent indications for the OP CE exams (P = 0.002 and P = 0.01, respectively. Occult OGB was the most common indication and arteriovenous malformations were the most common finding both in the IPs and OPs. The capsule did not enter the small bowel (SB in 6/70 IPs and 8/264 OPs (P = 0.04. The capsule never reached the cecum in 31.4% (22/70 of IP vs 9.5% (25/ 264 of OP examinations (P < 0.001. The mean gastric transit time (GTT was delayed in IPs compared to OPs, 98.5 ± 139.5 min vs 60.4 ± 92.6 min (P = 0.008. Minimal SB transit time was significantly prolonged in the IP compared to the OP setting [IP = 275.1 ± 111.6 min vs OP = 244.0 ± 104.3 min (P = 0.037]. CECR was also significantly higher in the subgroup of patients with OGB who had OP vs IP exams (95% vs 80% respectively, P = 0.001. The proportion of patients with incomplete exams was higher in the ICU (n = 7/13, 54% as compared to the GMF (n = 15/57, 26% (P = 0.05. There was only a single permanent SB retention case which was secondary to a previously unknown SB stricture, and the remaining incomplete SB exams were due to slow transit. Medications which affect gastrointestinal system motility were tested both individually and also in aggregate in univariate analysis in hospitalized patients (ICU and GMF and were not predictive of incomplete capsule passage (P > 0.05. Patient location (IP vs OP and GTT were independent predictors of incomplete CE exams (P < 0.001 and P = 0.008, respectively. CONCLUSION: Incomplete CE is a multifactorial problem. Patient location and related factors such as severity of illness and sedentary status may contribute to incomplete exams.

  14. Small bowel obstruction secondary to migration of a fragment of lithobezoar: a case report.

    Medani, Mekki

    2009-01-01

    INTRODUCTION: Small bowel obstruction is a common world-wide condition that has a range of etiological factors. The management is largely dependent on the cause of the obstruction. Small bowel obstruction caused by foreign body ingestion is rare; many items have been reported as responsible, but there are no reports implicating polyurethane foam. CASE PRESENTATION: We report the case of a 44-year-old Irish male who presented following ingestion of polyurethane foam. He was asymptomatic on presentation but developed a small bowel obstruction shortly thereafter. CONCLUSION: Patients presenting following ingestion of polyurethane foam should be scheduled for elective laparotomy, gastrotomy, and retrieval of the cast on the next available theatre list - given that they are suitable for surgery.

  15. Carcinoid tumors of the small-bowel: Evaluation with 64-section CT-enteroclysis

    International Nuclear Information System (INIS)

    Purpose: To describe the imaging presentation of carcinoid tumors of the small-bowel at 64-section CT-enteroclysis and determine the sensitivity of this technique for tumor detection. Patients and methods: The 64-section CT-enteroclysis examinations of 22 patients with histopathologically proven small-bowel carcinoid tumors and those of 6 patients with suspected recurrence after small-bowel resection for carcinoid tumor were reviewed. Images were analyzed with respect to imaging presentation. Sensitivity, specificity, and accuracy, of 64-section CT-enteroclysis for the diagnosis of carcinoid tumor of the small-bowel were estimated with 95% confidence intervals (CIs). Results: Twenty-five carcinoid tumors were confirmed in 22 patients (prevalence, 22/28; 79%). Overall sensitivity for carcinoid tumor detection was 76% (19/25; 95%CI: 55–91%) on a per-lesion basis. On a per-patient basis, 64-section CT-enteroclysis had a sensitivity of 86% (19/22; 95%CI: 65–97%), a specificity of 100% (6/6; 95%CI: 54–100%) and an accuracy of 89% (25/28; 95%CI: 72–98%) for the diagnosis of carcinoid tumor. Focal small-bowel wall thickening, mesenteric stranding, and mesenteric mass were found in 20/22 (91%), 18/22 (82%) and 15/22 (68%) patients with pathologically confirmed tumors. Conclusion: 64-Section CT-enteroclysis shows highly suggestive features for the diagnosis of carcinoid tumor of the small-bowel and achieves high degrees of sensitivity for tumor detection

    2013-02-01

    Small bowel obstruction is a complication of laparoscopic Roux-en-Y gastric bypass (LRYGB) frequently caused by adhesions and internal hernia. In addition, anastomotic leak that complicates LRYGB surgery contributes to the mortality of this procedure. Fibrin glue is commonly used intraoperatively for prevention of anastomotic leak and to secure hemostasis. We describe 2 cases of morbidly obese women who underwent LRYGB surgery for weight loss and developed early postoperative small bowel obstruction related to the use of the "EVICEL" fibrin sealant. Of note is that both patients required surgical intervention for this complication. PMID:23386172

    1986-01-01

    The amount of starch escaping absorption in the small intestine was measured in eight patients with symptomatic diverticular disease and eight controls. Unabsorbed starch was calculated from breath hydrogen measurements after a potato meal compared with the hydrogen response to lactulose. The proportion of unabsorbed starch was low in all the patients (mean 3.3%) and was only about a quarter of that in the controls (12.4%; p less than 0.01). These findings confirm that unabsorbed starch provi...

  19. Software-assisted quantitative analysis of small bowel motility compared to manual measurements

    International Nuclear Information System (INIS)

    Aim: To validate a newly developed software prototype that automatically analyses small bowel motility by comparing it directly with manual measurement. Material and methods: Forty-five patients with clinical indication for small bowel magnetic resonance imaging (MRI) were retrospectively included in this institutional review board-approved study. MRI was performed using a 1.5 T system following a standard MR-enterography protocol. Small bowel motility parameters (contractions-per-minute, luminal diameter, amplitude) were measured three times each in identical segments using the manual and the semiautomatic software-assisted method. The methods were compared for agreement, repeatability, and time needed for each measurement. All parameters were compared between the methods. Results: A total of 91 small-bowel segments were analysed. No significant intra-individual difference (p > 0.05) was found for peristaltic frequencies between the methods (mean: 4.14/min manual; 4.22/min software-assisted). Amplitudes (5.14 mm; 5.57 mm) and mean lumen diameters (17.39 mm; 14.68) differed due to systematic differences in the definition of the bowel wall. Mean duration of single measurement was significantly (p < 0.01) shorter with the software (6.25 min; 1.30 min). The scattering of repeated measurements was significantly (p < 0.05) lower using the software. Conclusion: The software-assisted method accomplished highly reliable, fast and accurate measurement of small bowel motility. Measurement precision and duration differed significantly between the two methods in favour of the software-assisted technique

    The use of magnetic resonance enterography (MRE) has become a mainstay in the evaluation, assessment and follow up of inflammatory bowel diseases, such as Crohn's disease (CD), thanks to its high image quality and its non-ionizing nature. In particular, the advent of faster MRE sequences less sensitive to image-motion artifacts offers the possibility to obtain visual, structural and functional information of the patient's small bowel. However, the inherent subjectivity of the mere visual inspection of these images often hinders the accurate identification and monitoring of the pathological areas. In this paper, we present a framework that provides quantitative and objective motility information of the small bowel from free-breathing MRE dynamic sequences. After compensating for the breathing motion of the patient, we create personalized peristaltic activity maps via optical flow analysis. The result is the creation of a new set of images providing objective and precise functional information of the small bowel. The accuracy of the new method was also evaluated from two different perspectives: objective accuracy (1.1 ± 0.6 mm/s of error), i.e., the ability of the system to provide quantitative and accurate information about the motility of moving bowel landmarks, and subjective accuracy (avg. difference of 0.7 ± 0.7 in a range of 1 to 5), i.e., the degree of agreement with the subjective evaluation of an expert. Finally, the practical utility of the new method was successfully evaluated in a preliminary study with 32 studies of healthy and CD cases, showing its potential for the fast and accurate assessment and follow up of CD in the small bowel.

O abscesso diverticular (Hinchey graus I, II) pode ser inicialmente tratado somente com antibióticos e / ou drenagem percutânea, dependendo do tamanho do abcesso. A peritonite purulenta generalizada (Hinchey III) pode ser tratada pelo clássico procedimento Hartmann, pela exteriorização da perfuração, como se fosse um estoma, pela ressecção primária com ou sem anastomose, com ou sem desvio do trânsito e, por último, a simples lavagem laparoscópica, geralmente, sem drenagem. A peritonite por fezes (Hinchey IV), uma indicação para o tradicional procedimento de Hartmann, também pode se beneficiar da ressecção primária seguida de anastomose, com ou sem desvio e lavagem laparoscópica. A obstrução aguda (inflamação local, ou aderências, formação pseudotumoral, estenoses crônicas) e fístula são, na maioria das vezes, tratadas por ressecção, preferencialmente, laparoscópica. Algoritmos terapêuticos pouco invasivos combinadas com indicações menos rigorosas para a o emprego da cirurgia radical antes de um padrão definido de recorrência, estão estabelecidos, ocasionando um número menor de ressecções e / ou estomas, reduzindo a morbidade e a mortalidade, melhorando a qualidade de vida após a intervenção, e geram uma tratamento menos dispendioso.

Diverticular abscesses (Hinchey Grades I, II) may be initially treated by antibiotics alone and/or percutaneous drainage, depending on the size of the abscess. Generalized purulent peritonitis (Hinchey III) may be treated by the classic Hartmann procedure, or exteriorization of the perforation as a stoma, primary resection with or without anastomosis, with or without diversion, and last, simple laparoscopic lavage, usually even without drainage. Feculent peritonitis (Hinchey IV), a traditional indication for Hartmann's procedure, may also benefit from primary resection followed by anastomosis, with or without diversion, and even laparoscopic lavage. Acute obstruction (nearby inflammation, or adhesions, pseudotumoral formation, chronic strictures) and fistula are most often treated by resection, ideally laparoscopic. Minimal invasive therapeutic algorithms that, combined with less strict indications for radical surgery before a definite recurrence pattern is established, has definitely lead to fewer resections and/or stomas, reducing their attendant morbidity and mortality, improved post-interventional quality of life, and less costly therapeutic policies.

    Aim: To investigate the frequency, clinical significance, and outcome of small-bowel intussusceptions in adults detected using ultrasound in an outpatient setting. Patients and methods: In two different retrospective (January 2001 to April 2003) and prospective (May 2003 to June 2005) periods, 33 small-bowel intussusceptions were found in 32 patients (13 females; mean age: 38.1 years) with known or suspected intestinal disease. Patients underwent diagnostic work-up to assess any organic disease. Patients with self-limiting intussusception were submitted to clinical and ultrasonographic follow-up. Results: Of the 32 patients with small-bowel intussusception, 25 were identified in the prospective series of 4487 examinations (0.53%) and seven in the retrospective series of 5342 examinations (0.15%; p = 0.002). Four patients had persistent and 28 self-limiting intussusceptions. Self-limiting intussusceptions were idiopathic in 11 patients (39%) or associated with organic diseases in 17 (Crohn's disease in 11 patients, celiac disease in three, ulcerative colitis in one patient, and previous surgery for cancer in two). Self-limiting intussusceptions were asymptomatic in 25% of patients. Conclusion: Small-bowel intussusceptions in adults are not rare and are frequently self-limiting, idiopathic, or related to organic diseases, mainly Crohn's disease and coeliac disease.

    Full Text Available The incidence of chronic diarrhea in Asia is between 0.8-1.0%. The diseases and abnormalities according to the location, which can cause chronic diarrhea, are divided into three locations: the small bowel, the large bowel and extraintestinal. The small bowel diseases include infectious and non-infectious diseases. The infectious diseases are bacterial infections, parasitic infections etc. The non-infectious diseases include of Crohn’s disease, Celiac sprue, NSAID enteropathy, lactose intolerance, benign tumor, carcinoid tumor, carcinoma, post surgery complications, laxative etc. The approaches to diagnosis include good anamnesis, careful physical examination, supporting laboratory tests, more specialized supporting examinations including X-ray of the colon, esophagogastroduodenum follow-through, enteroclysis, ileo-colonoscopy and endoscopy on the upper portion of the digestive tract including the small intestine with biopsy for histopathology examinations. The treatment for chronic diarrhea is divided into supportive and causal therapy. (Med J Indones 2002; 11: 179-89 Keywords: small bowel, chronic diarrhea, approaches to diagnosis, treatment

History and demographic data were taken, as well as the history of non-steroidal anti-inflammatory drug (NSAID consumption. After reading each VCE recording, a capsule endoscopy scoring index for small bowel mucosal inflammatory change (Lewis score was calculated. Statistical analysis of the data was performed.RESULTS: The Lewis score for the whole cohort was 397.73. It was higher in the NSAID consumption subgroup (P = 0.036. The difference in Lewis score between NSAID users and non-users was reproduced for the first and second proximal tertiles of the small bowel, but not for its distal third (P values of 0.036, 0.001 and 0.18, respectively. There was no statistical significant difference between the groups with regard to age or sex of the patients.CONCLUSION: The intestinal inflammatory involvement of SpA patients is more prominent in NSAID users for the proximal/mid small bowel, but not for its distal part.

    Conventional endoscopic exams do not allow the entire visualization of the gastrointestinal (GI) tract. Push enteroscopy (PE) is an effective diagnostic and therapeutic procedure, although it only allows exploration of the proximal small bowel (Pennazio et al., 1995). Simultaneously, convetional colonoscopy is limited at the terminal ileum. Therefore, prior to the wireless capsule endoscopy era, the small intestine was the conventional endoscopy’s last frontier, because it could not b...

    MR and CT techniques optimized for small bowel imaging are playing an increasing role in the evaluation of small bowel disorders. Several studies have shown the advantage of these techniques over tradition barium fluoroscopic examinations secondary to improvements in spatial and temporal resolution combined with improved bowel distending agents. The preference of MR vs. CT has been geographical and based on expertise and public policy. With the increasing awareness of radiation exposure, there has been a more global interest in implementing techniques that either reduce or eliminate radiation exposure [Brenner DJ, Hall EJ. Computed tomography-an increasing source of radiation exposure. N Engl J Med 2007;357:2277-84]. This is especially important in patients with chronic diseases such as inflammatory bowel disease who may require multiple studies over a lifetime or in studies that require sequential imaging time points such as in assessment of gastrointestinal motility [Froehlich JM, Patak MA, von Weymarn C, Juli CF, Zollikofer CL, Wentz KU. Small bowel motility assessment with magnetic resonance imaging. J Magn Reson Imaging 2005;21:370-75]. A recent study showed that certain subgroups of patients with Crohn's disease may be exposed to higher doses of radiation; those diagnosed at an early age, those with upper tract inflammation, penetrating disease, requirement of intravenous steroids, infliximab or multiple surgeries [Desmond AN, O'Regan K, Curran C, et al. Crohn's disease: factors associated with exposure to high levels of diagnostic radiation. Gut 2008;57:1524-29]. Therefore it has been suggested that techniques that can reduce or eliminate radiation exposure should be considered for imaging [Brenner DJ, Hall EJ. Computed tomography-an increasing source of radiation exposure. N Engl J Med 2007;357:2277-84]. Owing to the excellent softtissue contrast, direct multiplanar imaging capabilities, new ultrafast breath-holding pulse sequences, lack of ionizing radiation and availability of a variety of oral contrast agents, MR is well suited to play a critical role in the imaging of small bowel disorders. In this article we will review the technical issues related to the performance of MR enterography and enteroclysis and discuss the role and controversies of using MR in the assessment of inflammatory bowel disease.

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

    Full Text Available AIM: To analyze the clinical characteristics of small bowel tumors detected by double-balloon enteroscopy (DBE and to evaluate the diagnostic value of DBE in tumors. METHODS: Four hundred and forty consecutive DBE examinations were performed in 400 patients (250 males and 150 females, mean age 46.9 ± 16.3 years, range 14-86 years between January 2007 and April 2012. Of these, 252 patients underwent the antegrade approach, and 188 patients underwent the retrograde approach. All the patients enrolled in our study were suspected of having small bowel diseases with a negative etiological diagnosis following other routine examinations, such as upper and lower gastrointestinal endoscopy and radiography tests. Data on tumors, such as clinical information, endoscopic findings and operation results, were retrospectively collected. RESULTS: Small bowel tumors were diagnosed in 78 patients, of whom 67 were diagnosed using DBE, resulting in a diagnostic yield of 16.8% (67/400; the other 11 patients had negative DBE findings and were diagnosed through surgery or capsule endoscopy. Adenocarcinoma (29.5%, 23/78, gastrointestinal stromal tumor (24.4%, 19/78 and lymphoma (15.4%, 12/78 were the most common tumors. Among the 78 tumors, 60.3% (47/78 were located in the jejunum, and the overall number of malignant tumors was 74.4% (58/78. DBE examinations were frequently performed in patients with obscure gastrointestinal bleeding (47.4% and abdominal pain (24.4%. The positive detection rate for DBE in the 78 patients with small bowel tumors was 85.9% (67/78, which was higher than that of a computed tomography scan (72.9%, 51/70. Based on the operation results, the accuracy rates of DBE for locating small bowel neoplasms, such as adenocarcinoma, gastrointestinal stromal tumor and lymphoma, were 94.4%, 100% and 100%, respectively. The positive biopsy rates for adenocarcinoma and lymphoma were 71.4% and 60%, respectively. CONCLUSION: DBE is a useful diagnostic tool with high clinical practice value and should be considered the gold standard for the investigation of small bowel tumors.

  17. 14C-oxalic acid resorption in patients with small bowel resection, jejunoileal bypass, Crohn's disease, and chronic pancreatitis

    International Nuclear Information System (INIS)

    The enteric absorption of oxalic acid was determined with 14C-oxalic acid in patients with small bowel resection, jejunoileal bypass, Crohn's disease and chronic pancreatitis in comparison to the control group. Extreme hyperoxaluria was found in small bowel resections above 100 cm, after bypass operations and in ileocolitis Crohn with signs of clinical activity. Small bowel resections and relapses of Crohn's disease increase the absorption of oxalic acid. The significance of 14C-oxalic acid absorption test is the recognition of enteric hyperoxaluria.

  18. Experience with an alternative contrast medium in oral small bowel imaging

    International Nuclear Information System (INIS)

    Purpose: The image quality of oral small bowel imaging is often poor on account of the small bowel enema. A new contrast medium should increase the image quality due to better compliance of patient because of the better taste of substance. The loading of patient with radiation or time should not increase. Methods and patients: We investigated prospectively 40 patients, randomized in two groups of 20 patients each. Two different substances were used as contrast medium: barium-methylcellulose and Barium-Mucofalk trademark, respectively. The quality of the double contrast, profile of the mucosa, duration of radiation, duration of examination, dose-area product, and taste of the substance were judged for significance. Results: The taste of the new contrast medium was judged to be better: twice as often as ''good'' and five times less often as ''bad'', the difference was not significant due to the small number of patients. There is no significant difference in the other criterias. Conclusion: Mucofalk trademark is an alternative contrast medium for oral small bowel radiology in cases of difficult placement of the tube for enema. The quality of double contrast and visualization of the profile of mucosa are the same while the taste is better. (orig.)

    Full Text Available AIM: To evaluate the influence of taking low-dose aspirin for 4 wk on small intestinal complications and to examine the preventive effect of rebamipide. METHODS: This study was conducted as a single-center, randomized, double-blind, cross-over, placebo-controlled study. Eleven healthy male subjects were enrolled. Each subject underwent video capsule endoscopy after 1 and 4 wk of taking aspirin and omeprazole, along with either rebamipide or placebo therapy. The primary endpoint was to evaluate small bowel damage in healthy subjects before and after taking low-dose aspirin for 4 wk. RESULTS: The number of subjects with mucosal breaks (defined as multiple erosions and/or ulcers were 1 at 1 wk and 1 at 4 wk on the jejunum, and 6 at 1 wk (P = 0.0061 and 7 at 4 wk on the ileum (P = 0.0019. Rebamipide significantly prevented mucosal breaks on the ileum compared with the placebo group (P = 0.0173 at 1 wk and P = 0.0266 at 4 wk. CONCLUSION: Longer-term, low-dose aspirin administration induced damage in the small bowel. Rebamipide prevented this damage, and may be a candidate drug for treating aspirin-induced small bowel complications.

  20. Thinking beyond the colon-small bowel Involvement in clostridium difficile infection

    Directory of Open Access Journals (Sweden)

    2009-03-01

    Full Text Available Abstract Small intestinal Clostridium difficile seems to be increasing in incidence. The spectrum of Clostridium difficile infection (CDI has definitely expanded with small bowel involvement. They are more frequently reported in patients with inflammatory bowel disease (IBD who have undergone total colectomy or patients with Ileal anal pouch anastomosis. The most common presentation is increased ileostomy output with associated dehydration. High clinical suspicion, early recognition and appropriate treatment are the keys to successful resolution. The increase in the number of these patients may actually reflect an increase in the rising incidence of CDI in general or increasing virulence of the organism. Heightened public awareness and initiation of prompt preventive measures are the keystones to control of this infection. This disease is no longer limited to the colon and physicians should be educated to think beyond the colon in patients with CDI.

  1. Posterolateral diaphragmatic hernia with small-bowel incarceration in an adult

    Scientific Electronic Library Online (English)

    G, Wenzel-Smith.

    Full Text Available Bochdalek hernia (BH), a closing defect ofthe peripheral posterior aspect ofthe diaphragm, is the most common ofthe congenital diaphragmatic hernias and is usually diagnosed in neonates. Symptomatic presentation of a right-sided diaphragmatic hernia in an adult is unusual. Owing to their rarity and [...] varied presentation, these hernias can pose a diagnostic challenge. A right-sided BH in a 40-year-old woman who presented with respiratory distress associated with abdominal pain and symptoms of small-bowel obstruction is reported. Midline laparotomy revealed necrotic small bowel and faecothorax of the pleural cavity. Diaphragmatic hernias should be included in the differential diagnosis of patients with acute or chronic gastrointestinal, or less frequently respiratory, symptoms.

  12. Accuracy of enteroclysis in Crohn's disease of the small bowel: a retrospective study

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the accuracy of enteroclysis in the diagnosis of Crohn's disease of the small bowel in a group of consecutive patients. From January 1992 to December 1995, 165 patients with suspected Crohn's disease of the small bowel presented to our institution for enteroclysis. In 14 patients up to three enteroclysis exams were performed. Most patients (78 %) underwent colonoscopy and retrograde ileoscopy. In the remaining patients clinical follow-up was used as gold standard. In 79 patients no radiographic abnormalities were found. Sixty-one patients (40 men and 21 women; mean age 34.2 years) had a radiological diagnosis of Crohn's disease. This involved the terminal ileum in 39 patients (64 %) either alone (n = 25) or in association with the pelvic ileum (n = 14). In 12 of these patients retrograde ileoscopy was not feasible. Twenty-one patients underwent surgery. In 4 patients pathology revealed diseases other than Crohn's. These patients had all ileocecal diseases (tuberculosis = 2; non-Hodgkin's lymphoma = 1; adenocarcinoma = 1). One false-negative result was observed. Overall, enteroclysis showed a sensitivity of 98.2 % and a positive predictive value of 93.4 %. Enteroclysis is a sensitive technique in evaluating both the extent and the severity of small bowel involvement in Crohn's disease, although the overlap of radiographic findings may hamper its accuracy when the disease is confined to the ileocecal area.

    Objective: To assess the value of enhanced MSCT scan for the Crohn's disease of small bowel. Methods: Fourty-five patients of small bowel Crohn's disease who were proved by multi-method were examined by two-phase enhanced scan with MSCT. The images were reformed in ADW 4.2 by MPR mainly. The CT values of the lesion segments in different phases were tested, with one way ANOVA in statistical analysis; the density difference between the lesion segments and normal segments in different phases were tested, the cases were divided according to 10 HU, and compared them with each other by ?2 test. Results: The average CT value of lesion segments was (39.3±3.7) HU in plain scan, (74.8±13.8) HU in artery phase, (90.2±12.3) HU in portal vein phase, there were sinigicant difference in them (F=258.87, P10 HU respectively in plain scan, 6 cases and 39 cases in artery phase, 2 cases and 43 cases in portal vein phase, by ?2 test, there were sinigicant difference between plain scan and artery phase (?2=32.49, P2= 39.22, P2= 1.10, P>0.05). After enhancement, the lesions can display clearly than plain scan, and the detectable rate was raised highly. Conclusion: Two-phase enhancement scan can diagnosis the Crohn's disease of small bowel and evaluate it overall. (authors)

    Objective: This study aims to evaluate the effects of different oral small bowel contrast agents towards the intestinal dilatation and intestinal wall structure exhibition by the abdominal multi - detector row CT (MDCT) examination. Methods: 80 patients were performed the whole abdominal CT examination, then randomly divided into four groups, with 20 patients in each group. 45 minutes before the CT examination, the patients were served with a total of 1800 ml pure water, pure milk, dilute lactulose solution and isotonic mannitol solution, respectively. Results: The images were blinded read by two experienced abdominal radiologists in the workstation, the cross-sectional diameters of duodenum, jejunum, proximal and terminal ends of ileum of each patient were measured, then the analysis of variance was performed to analyze the differences in the intestinal dilatation among the experimental groups. The scoring method was used to score the intestinal dilatation and intestinal structure exhibition. The diluted lactulose solution and 2.5% mannitol exhibited the best intestinal dilation degrees. Similarly, the diluted lactulose solution and 2.5% mannitol exhibited the highest scores in the entire small bowel dilatation degree and intestinal structure exhibition. Conclusions: 2.5% osmotic mannitol and the diluted lactulose solution enabled the full dilatation of small bowel, and could clearly exhibit the wall structure.

    LENUS (Irish Health Repository)

    O'Daly, Brendan J

    2009-06-01

    BACKGROUND: Predicting the clinical course in adhesional small bowel obstruction is difficult. There are no validated clinical or radiologic features that allow early identification of patients likely to require surgical intervention. METHODS: We conducted a retrospective review of 100 patients consecutively admitted to a tertiary level teaching hospital over a 3-year period (2002-2004) who had acute adhesional small bowel obstruction and underwent computed tomography (CT). The primary outcomes that we assessed were conservative management or the need for surgical intervention. We investigated time to physiologic gastrointestinal function recovery as a secondary outcome. We examined independent predictors of surgical intervention in a bivariate analysis using a stepwise logistic regression analysis. RESULTS: Of the 100 patients investigated, we excluded 12. Of the 88 remaining patients, 58 (66%) were managed conservatively and 30 (34%) underwent surgery. Peritoneal fluid detected on a CT scan (n = 37) was associated more frequently with surgery than conservative management (46% v. 29%, p = 0.046, chi(2)). Logistical regression identified peritoneal fluid detected on a CT scan as an independent predictor of surgical intervention (odds ratio 3.0, 95% confidence interval 1.15-7.84). CONCLUSION: The presence of peritoneal fluid on a CT scan in patients with adhesional small bowel obstruction is an independent predictor of surgical intervention and should alert the clinician that the patient is 3 times more likely to require surgery.

    Full Text Available AIM: To investigate the effect of mesalazine granules on small intestinal injury induced by naproxen using capsule endoscopy (CE. METHODS: This was a single center, non-randomized, open-label, uncontrolled pilot study, using the PillCam SB CE system with RAPID 5 software. The Lewis Index Score (LIS for small bowel injury was investigated to evaluate the severity of mucosal injury. Arthropathy patients with at least one month history of daily naproxen use of 1000 mg and proton pump inhibitor co-therapy were screened. Patients with a minimum LIS of 135 were eligible to enter the 4-wk treatment phase of the study. During this treatment period, 3 × 1000 mg/d mesalazine granules were added to ongoing therapies of 1000 mg/d naproxen and 20 mg/d omeprazole. At the end of the 4-wk combined treatment period, a second small bowel CE was performed to re-evaluate the enteropathy according to the LIS results. The primary objective of this study was to assess the mucosal changes after 4 wk of mesalazine treatment. RESULTS: A total of 18 patients (16 females, ranging in age from 46 to 78 years (mean age 60.3 years were screened, all had been taking 1000 mg/d naproxen for at least one month. Eight patients were excluded from the mesalazine therapeutic phase of the study for the following reasons: the screening CE showed normal small bowel mucosa or only insignificant damages (LIS < 135 in five patients, the screening esophagogastroduodenoscopy revealed gastric ulcer in one patient, capsule technical failure and incomplete CE due to poor small bowel cleanliness in two patients. Ten patients (9 female, mean age 56.2 years whose initial LIS reached mild and moderate-to-severe enteropathy grades (between 135 and 790 and ? 790 entered the 4-wk therapeutic phase and a repeat CE was performed. When comparing the change in LIS from baseline to end of treatment in all patients, a marked decrease was seen (mean LIS: 1236.4 ± 821.9 vs 925.2 ± 543.4, P = 0.271. Moreover, a significant difference between pre- and post-treatment mean total LIS was detected in 7 patients who had moderate-to-severe enteropathy gradings at the inclusion CE (mean LIS: 1615 ± 672 vs 1064 ± 424, P = 0.033. CONCLUSION: According to the small bowel CE evaluation mesalazine granules significantly attenuated mucosal injuries in patients with moderate-to-severe enteropathies induced by naproxen.

  20. Virtual endoscopy of the small bowel: phantom study and preliminary clinical results

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the optimal scanning technique for lesion detection in a small bowel phantom and to evaluate the virtual endoscopy (VE) technique in patients. A small bowel phantom with a fold thickness of 7 mm and length of 115 cm was prepared with nine round lesions (3 x 1 mm, 2 x 2 mm, 2 x 3 mm, 2 x 4 mm). Spiral CT parameters were 7/7/4, 3/5/2, 3/5/1, 1.5/3/1 (slice thickness/table feed/reconstruction interval). VE was done using volume rendering technique with 1 cm distance between images and 120 viewing angle. Two masked readers were asked to determine the number and location of the lesions. Seven patients underwent an abdominal CT during one breathhold after placement of a duodenal tube and filling of the small bowel with methyl cellulose contrast solution. VE images were compared with the axial slices with respect to detectability of pathology. With the 7/7/4 protocol only the 4-mm lesions were visualised with fuzzy contours. The 3/5/2 protocol showed both 4-mm lesions, one 3-mm lesion and one false positive lesion. The 3/5/1 protocol showed both 4-mm and both 3-mm (one uncertain) lesions with improved sharpness, and no false positive lesions. One 2-mm and one 1-mm lesion were additionally seen with the 1.5/3/1 protocol. Path definition was difficult in sharp turns or kinks in the lumen. In all patients, no difference was found between VE and axial slices for bowel pathology; however, axial slices showed 'outside' information that was not included in VE. We conclude that the 3/5/2 protocol may be regarded as an optimal compromise between lesion detection, coverage during one breathhold, and number of reconstructed images in patients; round lesions of 4 mm in diameter can be detected with high certainty.

  1. An experimental study on radiological examination of obstructed small bowel with various contrast media

    International Nuclear Information System (INIS)

    For the evaluation of the level and cause of small bowel obstruction, an oral barium study is usually chosen. When perforation is whether barium or a water-soluble contrast agent should be used, because barium causes from foreign body reactions as well as adhesions in the extraluminal tissues. Water-soluble contrast agent, on the other hand, are less satisfactory but in general have no untoward effects in the extraluminal tissues. Because of hyperosomolarity, water-soluble contrast agents attract large amounts of fluid with subsequent dilution and loss of contrast and pose a risk of pulmonary edema if aspirated. The use of the newer non-ionic and low-osmolarity water-soluble contrast will likely avoid pulmonary complications due to aspiration. The author performed this experimental study to compare the radiological efficacy of different contrast media in enteric follow-through examinations of obstructed small bowel. Rate had a ligature applied to the distal ileum via laparotomy. Four contrast media were subjected to testing by instillation via oro-gastric tube immediately after laparotomy. Radiographs were exposed at 1, 4 and 8 hours and evaluated later. After 24 hours the animals were sacrificed and the stomach and small bowels, free from mesentery and omental tissue, were weighted with contrasts. The progression in the bowel was proportionate to the osmolarity of the contrast media. After 1 hour, the observations indicated sodium diatrizoate (Gastrografin, Schering) to be the least favorable medium with respect to sharpness of the mucosal border. After 8 hours, barium gave a poorer delineation compared to Ioxaglate (Hexabric, Guerbet) and Iopromide (Ultravist, Schering). Early deaths were noted in the sodium diatrizoate and ioxaglate groups. So we conclude that when using a rather high-volume bolus, low-osmolar non-ionic contrast media seem to have significant prospects for general diagnostic use in patients with suspected intestinal obstruction

    For the evaluation of the level and cause of small bowel obstruction, an oral barium study is usually chosen. When perforation is whether barium or a water-soluble contrast agent should be used, because barium causes from foreign body reactions as well as adhesions in the extraluminal tissues. Water-soluble contrast agent, on the other hand, are less satisfactory but in general have no untoward effects in the extraluminal tissues. Because of hyperosomolarity, water-soluble contrast agents attract large amounts of fluid with subsequent dilution and loss of contrast and pose a risk of pulmonary edema if aspirated. The use of the newer non-ionic and low-osmolarity water-soluble contrast will likely avoid pulmonary complications due to aspiration. The author performed this experimental study to compare the radiological efficacy of different contrast media in enteric follow-through examinations of obstructed small bowel. Rate had a ligature applied to the distal ileum via laparotomy. Four contrast media were subjected to testing by instillation via oro-gastric tube immediately after laparotomy. Radiographs were exposed at 1, 4 and 8 hours and evaluated later. After 24 hours the animals were sacrificed and the stomach and small bowels, free from mesentery and omental tissue, were weighted with contrasts. The progression in the bowel was proportionate to the osmolarity of the contrast media. After 1 hour, the observations indicated sodium diatrizoate (Gastrografin, Schering) to be the least favorable medium with respect to sharpness of the mucosal border. After 8 hours, barium gave a poorer delineation compared to Ioxaglate (Hexabric, Guerbet) and Iopromide (Ultravist, Schering). Early deaths were noted in the sodium diatrizoate and ioxaglate groups. So we conclude that when using a rather high-volume bolus, low-osmolar non-ionic contrast media seem to have significant prospects for general diagnostic use in patients with suspected intestinal obstruction.

    Systemically administered misoprostol, a PGE analog, has been shown to be an intestinal radioprotector. The purpose of this study was to determine if administration of misoprostol into the intestinal lumen can also reduce the severity of acute radiation enteritis. The rat small bowel was operatively exteriorized and segmented by means of suture ties. The remainder of the intestine and the rat were shielded in a lead box. Misoprostol was introduced into the lumen in various doses. After 30 min exposure to misoprostol, the isolated, exteriorized, segmented bowel was subjected to 11 Gy X irradiation. Five days later the animals were sacrificed and the intestines harvested for evaluation. Surviving crypt numbers per circumference and mucosal height were the criteria used for quantification of damage. Mucosa exposed to misoprostol at the time of radiation delivery showed significantly increased crypt numbers and mucosal height compared to adjacent saline-filled intestine. 24 refs., 2 figs., 2 tabs.

  5. Metastatic Deposits of Breast Lobular Carcinoma to Small Bowel and Rectum

    International Nuclear Information System (INIS)

    Breast cancer is the most frequent malignancy in women accounting for approximately 32% of all cancers, with a lifetime risk of 1 in 10. It causes considerable morbidity and mortality. Recently, the survival rate has dramatically increased due to early detection of the disease and improvement in the treatment measures. However, more than 30% of the patients develop metastatic diseases following surgical treatment, radiotherapy, hormonal therapy, or chemotherapy. Distant spread is usually found in bones, lungs, liver, brain and skin. Rarely, it spreads to bowel, spleen, gallbladder, pancreas, urinary bladder, and eyes. Breast cancer is the second commonest primary tumour responsible for gastrointestinal metastases after malignant melanoma. We report a case of a Caucasian female who developed an intestinal obstruction secondary to metastatic deposits to the small bowel and later to the rectum from breast lobular carcinoma 2 years after mastectomy, axillary clearance, radiotherapy, hormonal therapy, and transverse rectums abdomens myocutaneous (TRAM) flap for reconstruction.

    Full Text Available Simultaneous diagnosis of intussusception and appendicitis in the same patient have rarely been described in the pediatric population. We reported a small bowel intussusception case together with acute suppurative appendicitis. A 9 years old boy had abdominal colic pain and he had vomit frequently. On physical examination, he was awake, active and uncomfortable. Abdominal ultrasound (US suggested ileoileocolic intussusception. Laparotomy was performed and an ileoileocolic intussusception was visualized. Ileoileocolic intussusception was reducted manually. After reduction appendix was visualized and it was acute suppurative appendicitis. Appendectomy was performed. Neither medical nor surgical problem occurred during long term follow-up. In conclusion, we though that it is important to examine the other pathologic conditions such as leading points, bowel complications and even appendicitis in case of intussusception.

  7. Small bowel cleansing does not improve quality of wireless capsule endoscopy

    DEFF Research Database (Denmark)

    Wilkens, Rune; Langholz, Ebbe

    ABSTRACT: Background Wireless capsule endoscopy (WCE) is the most important tool for investigating obscure gastrointestinal bleeding in the small bowel and is superior to cross sectional imaging in detecting early and subtle inflammation of the small intestine in Crohn's Disease (CD). [1] With increasing demand of early diagnosis, WCE becomes more important. However, a drawback is the limited visualization of the mucosa in patients with poor cleansing quality. The aim of our study was to determine the benefit of preparation with Picoprep prior to examination with WCE and evaluate two different methods for cleansing quality. Methods This prospective cluster trial examined all patients from two Danish centres, who underwent WCE with PillCam SB based on either known or suspected small bowel CD or obscure bleeding from August 2013 to July 2014. Our local ethics committee waived the necessity of informed consent. Both Centres used the same instructions for preparation; the day before examination, normal breakfast and lunch was allowed until 2 pm, hereafter patients were instructed to go on a liquid diet. Only water was allowed the last two hours before the procedure. Site A, in addition to Site B, instructed patients to ingest one sachet of Picoprep powder, at 9 pm the day before examination, followed by 1.5 litres of liquid diet, as per standard of care at Site A. Patients were matched between centres based on indication, sex and age. Cleansing quality was assessed by two different methods described by Park et al. 2010 [2] with a 3 grade subjective assessment every 5 minutes and Weyenberg et al. 2011 [3] with a computer assessment of cleansing using the colour bar in the capsule reading software. Mean overall score between groups were compared using students ttest. Results We enrolled 135 consecutive patients allowing matching of 92 patients with a mean age of 45 years (16-83), 67 % women. CD was the indication in 69.6 %. Both scoring systems correlated well (rho = 0.80). Using both scoring systems, cleansing qualitydecreased significantly throughout the small bowel when comparing each third individually, p < 0.01. There were no overall difference in quality between groups. Conclusions Small bowel cleansing prior to WCE does not improve mucosal visualization of the small bowel in patients with suspected CD or obscure bleeding.

    The short-bowel syndrome is a clinical condition caused by intestinal resection. As intestinal adaptation occurs after resection, it can be used as a model for studying morphometric and biomechanical remodelling in the small intestine and to get a better understanding of the pathophysiology of the short-bowel syndrome. The resected rats had a 67% resection of jejunum and ileum. Control animals underwent no operation (nonoperated controls) or an ileal transection with subsequent end-to-end anastomosis (sham-resected controls). The animals were followed for up to 4 weeks after the operation. Changes in biomechanical properties were studied in terms of residual strain (the internal strain remaining when all external loads are removed), opening angle and stress--strain relations referenced to the zero-stress state (the cut-open state where external and internal stresses are released). The resected animals gained less weight than the controls. The intestinal length and diameter increased more in the resected groups than the control groups (P < 0.05), resulting in a larger absorptive surface. Resection induced profound gross morphometric changes and histological alterations characterized by proliferative increases in the tissue layers. The opening angle, along with residual strain at the mucosal and serosal surface, increased in the remnant small intestine (P < 0.05). All changes increased as function of postoperative time and were most prominent in the remnant ileum. However, the stress-strain relationship remained unchanged. In conclusion, this study demonstrated that resection of the majority of the small bowel results in significant remodelling in structural and residual strain properties in the remnant small intestine. The remodelling seems to be guided by the need for a greater absorptive surface area rather than for a change in the stress-strain properties.

  9. Serial intralesional injections of infliximab in small bowel Crohn's strictures are feasible and might lower inflammation

    2014-01-01

    BACKGROUND: Crohn's disease can cause strictures throughout the gastrointestinal tract. Endoscopic balloon dilatation is a well-established treatment, but recurrence is seen in up to three out of four cases. Infliximab is playing an increasingly important role in the modern systemic treatment of severe Crohn's disease. Combining the anti-inflammatory effects of infliximab with the proven effect of endoscopic balloon dilatation could possibly improve outcome. In small studies, intralesional injections in perianal fistulas have been effective and endoscopic injection therapy in colonic strictures is feasible. OBJECTIVE: We wanted to assess whether serial intralesional injection of infliximab in small bowel strictures is feasible and reduces local inflammation. METHODS: We included six patients with Crohn's disease and inflammatory small bowel strictures. They were treated with endoscopic serial balloon dilatation. Subsequent to each dilatation, 40 mg infliximab was injected submucosally. A modified simplifiedendoscopic score for Crohn's disease was used for the involved area before the initial treatment and at the final follow-up after six months. Complications and development of symptoms were registered. RESULTS: Balloon dilatation and serial injection of infliximab were accomplished in five out of six patients. One patient completed the serial balloon dilatations and follow-up but received only one infliximab injection. The modified simplified endoscopic score for Crohn's disease decreased in all patients. There were no adverse events registered and all patients described themselves as feeling well. CONCLUSIONS: Combining balloon dilatation of strictures with serial intralesional injection of infliximab in Crohn's disease of the small bowel is feasible and seems successful in reducing inflammation.

    Full Text Available Background: The effect of small bowel transit time (SBTT on diagnostic yield during capsule endoscopy (CE has not been previously evaluated. Our study aim was to assess the effect of SBTT on the likelihood of detecting intestinal pathology during CE. Methods: We reviewed collected data on CE studies performed at Johns Hopkins Hospital from January 2006 to June 2007. In patients investigated for anemia or obscure bleeding, the following lesions were considered relevant: ulcers, erosions, AVMs, red spots, varices, vascular ectasias, and presence of blood. In patients with diarrhea or abdominal pain, ulcers, erosions, and blood were considered relevant. Age, gender, study indication, hospital status, and quality of bowel preparation were identified as candidate risk factors affecting SBTT. Univariate logistic and linear regression analyses were performed to study the effect of SBTT on diagnostic yield. Results: Total of 212 CE studies were analyzed; most were in outpatients (n=175, 82.9% and with excellent bowel preparation (n=177, 83.5%. Mean SBTT was 237.0min (3.9hrs. Age, gender, bowel prep, hospital status, and study indication did not significantly affect SBTT. However, increased SBTT was independently associated with increased diagnostic yield; OR=1.7 in SBTT=2-4hr (p=0.41, OR=1.8 in SBTT=4-6hrs (p=0.30, OR=9.6 in SBTT=6-8hrs (p=0.05. Conclusion: Prolonged SBTT during CE (>6 hr is associated with an increased diagnostic yield. This may be due to a positive effect on image quality during a “slower” study. The use of promotility agents may adversely affect the ability of CE to detect significant intestinal pathology.

    To assess the differences in small bowel intussusceptions between children and adults, and to interpret the radiological findings requiring a surgical procedure. A total of 62 study subjects (35 children, 27 adults) with small bowel intussusception diagnosed by US or CT and seen between January 2005 and December 2007 were included in this study. Two radiologists retrospectively reviewed both the medical records and radiological findings of each study subject. We contrasted the range of features found to be typical of small bowel intussusception for both children and adults based on cause, abdominal symptoms, diagnostic tools, and treatments. Also, we evaluated the radiological findings requiring a surgical procedure. The causes of small bowel intussusception were not identified in children; however, 4 adults were found to have tumors (a lipoma, a hemangioma, 2 metastases) ({rho} = 0.031). All of the children (100%) and 8 adults (29.6%) had abdominal symptoms ({rho} < 0.001). The primary diagnostic tool in children was the US (31 cases, 88.6%), as opposed to the CT in adults (27 cases, 100%) ({rho} < 0.001). A spontaneous reduction was confirmed in all children (100%) and supposed in 23 adults (85.2%) ({rho} = 0.031). The noteworthy radiological findings of 4 study subjects having undergone a surgical procedure are masses at the lead point and small bowel obstruction ({rho} < 0.0001). Cases of small bowel intussusception in children are different from cases observed in adults, based on cause, symptoms, and diagnostic tools. However, most cases are spontaneously reduced. Important radiological findings requiring a surgical procedure were found to be caused by masses at the lead point and at the small bowel obstruction.

    Full Text Available In our previous work we demonstrated that the use of donor specific bone marrow infusions ( DSBMI after small bowel transplantation did not improve the graft survival after a short course of immunossupression. PURPOSE: In the current study, we evaluated whether recipient preconditioning with different regimens of radiation combined with DSBMI may enhance small bowel allograft survival with minimum recipient morbidity. METHODS: Heterotopic small bowel transplantation (SBTx was performed with Lewis rats as recipients and DA rats as donors, which were immunossupressed with a short course of tacrolimus (FK 506 at 1mg/Kg/day for 5 days and distributed in 4 groups: group 1 (n= 4 without both irradiation and DSBMI; Groups 2 (n= 6, 3 (n= 9 and 4 (n= 6 received 100 x 10(6 DSBM cells at the time of the transplant. Groups 3 and 4 were irradiated with 250 and 400 rd respectively. Animals were examined daily for clinical signs of rejection or GVHD. Blood samples were taken weekly for chimeric studies by FC and intestinal biopsies were performed every 2 weeks. RESULTS: Animals in G1 and G2 had minimal rejection at day 15 after SBTx while GVHD was clinically and histologically characterized in G 3 and G 4. Total chimerism and T-cell chimerism was higher in irradiated groups when compared to non-irradiated groups. With exception of G1 and 2 where rejection was the cause of death, all animals in G3 and 4 died of GVHD. CONCLUSION:We concluded that low cytoreductive of irradiation can successfully decrease the graft rejection but not prevent the occurrence of GVHD.

    Full Text Available We describe the ultrastructural abnormalities of the small bowel surface in 16 infants with persistent diarrhea. The age range of the patients was 2 to 10 months, mean 4.8 months. All patients had diarrhea lasting 14 or more days. Bacterial overgrowth of the colonic microflora in the jejunal secretion, at concentrations above 10(4 colonies/ml, was present in 11 (68.7% patients. The stool culture was positive for an enteropathogenic agent in 8 (50.0% patients: for EPEC O111 in 2, EPEC O119 in 1, EAEC in 1, and Shigella flexneri in 1; mixed infections due to EPEC O111 and EAEC in 1 patient, EPEC O119 and EAEC in 1 and EPEC O55, EPEC O111, EAEC and Shigella sonnei in 1. Morphological abnormalities in the small bowel mucosa were observed in all 16 patients, varying in intensity from moderate 9 (56.3% to severe 7 (43.7%. The scanning electron microscopic study of small bowel biopsies from these subjects showed several surface abnormalities. At low magnification (100X most of the villi showed mild to moderate stunting, but on several occasions there was subtotal villus atrophy. At higher magnification (7,500X photomicrographs showed derangement of the enterocytes; on several occasions the cell borders were not clearly defined and very often microvilli were decreased in number and height; in some areas there was a total disappearance of the microvilli. In half of the patients a mucus-fibrinoid pseudomembrane was seen partially coating the enterocytes, a finding that provides additional information on the pathophysiology of persistent diarrhea.

    Full Text Available Abstract Background In the developed world, small bowel obstruction accounts for 20% of all acute surgical admissions. The aetiology for majority of these cases includes postoperative adhesions and herniae. However, a relatively uncommon cause is a Meckel's diverticulum. Although this diagnosis is primarily reported in the adolescent population, it should also be considered in adults. Case Presentation In the present report, we present a rare case where a fit and healthy 74-year-old gentleman, with no previous history of abdominal surgery, presented with the cardinal symptoms and signs of small bowel obstruction as the result of a Meckel's diverticulum encircling his terminal ileum. Initial investigations included a supine abdominal x-ray showing dilated loops of small bowel and computerised tomographic imaging of the abdomen, which revealed a stricture in the terminal ileum of unknown aetiology. At laparotomy, multiple loops of distended small bowel were seen from the duodeno-jeujenal junction to the terminal ileum, which was encircled by a Meckel's diverticulum. The Meckel's diverticulum was then divided to release the obstruction, mobilised and subsequently removed. Finally, the small bowel contents were decompressed into the stomach and the nasogastric tube aspirated, before returning the loops of bowel into the abdomen in sequence. The patient made a good postoperative recovery and was discharged home 5 days later. Conclusion This report highlights the importance of considering a Meckel's diverticulum as a cause of small bowel obstruction in individuals from all age groups and especially in a person with no previous abdominal pathology or surgery.

    2013-01-01

    Full Text Available AIM: To investigate the disruptions of interstitial cells of Cajal (ICC in the remaining bowel in rats after massive small bowel resection (mSBR. METHODS: Thirty male Sprague-Dawley rats fitting entry criteria were divided randomly into three experimental groups (n = 10 each: Group A rats underwent bowel transection and re-anastomosis (sham and tissue samples were harvested at day 7 post-surgery. Group B and C rats underwent 80% small bowel resection with tissue harvested from Group B rats at day 7 post-surgery, and from Group C rats at day 14 post-surgery. The distribution of ICC at the site of the residual small bowel was evaluated by immunohistochemical analysis of small intestine samples. The ultrastructural changes of ICC in the remnant ileum of model rats 7 and 14 d after mSBR were analyzed by transmission electron microscopy. Intracellular recordings of slow wave oscillations were used to evaluate electrical pacemaking. The protein expression of c-kit, ICC phenotypic markers, and membrane-bound stem cell factor (mSCF in intestinal smooth muscle of each group were detected by Western blotting. RESULTS: After mSBR, immunohistochemical analysis indicated that the number of c-kit-positive cells was dramatically decreased in Group B rats compared with sham tissues. Significant ultrastructural changes in ICC with associated smooth muscle hypertrophy were also observed. Disordered spontaneous rhythmic contractions with reduced amplitude (8.5 ± 1.4 mV vs 24.8 ± 1.3 mV, P = 0.037 and increased slow wave frequency (39.5 ± 2.1 cycles/min vs 33.0 ± 1.3 cycles/min, P = 0.044 were found in the residual intestinal smooth muscle 7 d post mSBR. The contractile function and electrical activity of intestinal circular smooth muscle returned to normal levels at 14 d post mSBR (amplitude, 14.9 ± 1.6 mV vs 24.8 ± 1.3 mV; frequency, 30.7 ± 1.7 cycles/min vs 33.0 ± 1.3 cycles/min. The expression of Mscf and c-kit protein was decreased at 7 d (P = 0.026, but gradually returned to normal levels at 14 d. The ICC and associated neural networks were disrupted, which was associated with the phenotype alterations of ICC. CONCLUSION: Massive small bowel resection in rats triggered damage to ICC networks and decreased the number of ICC leading to disordered intestinal rhythmicity. The mSCF/c-kit signaling pathway plays a role in the regulation and maintenance of ICC phenotypes.

  16. Double-contrast small bowel examination: A methodical comparison between transnasal and peroral probing

    International Nuclear Information System (INIS)

    A new flexible probe to be introduced through the nose was used for the intubation of the jejunum for double-contrast small bowel enema. The new probe has a diameter of only 2.8 mm and was better tolerated than the normally applied Camus probe. Nevertheless, the failure rate (intubation of jejunum not successful) with the new probe as compared to the Camus probe was higher (17% versus 1%). We, therefore, conclude that the new probe should mainly be used by experienced examiners. (orig.)

    2011-07-01

    Full Text Available Meckel’s diverticulum occurs in 2% of the general population and majority of patients remain asymptomatic. Gastrointestinal bleeding is the most common presentation in the paediatric population. While asymptomatic and incidentally found Meckel’s diverticulum may be left alone, surgery is essential for treating a symptomatic patient. Despite advances in imaging and technology, pre-operative diagnosis is often difficult. We present a first report of an unusual mechanism of small bowel obstruction due to Meckel’s diverticulitis in a paediatric patient. The diagnosis was only apparent at laparotomy.

  19. Can diagnostic imaging reliably predict the need for surgery in small bowel obstruction? Critically appraised topic

    International Nuclear Information System (INIS)

    Small bowel obstruction (SBO) in many patients does not settle quickly. Surgeons often ask radiologists whether the SBO is resolving or is likely to resolve without surgery. In patients with SBO, can imaging reliably predict whether nonoperative management with be successful? Best current evidence was chosen according to the Oxford University National Health Service (NHS) Centre for Evidence-Based Medicine (CEBM) hierarchy of validity for studies of diagnosis. The retrieved studies were also categorized according to the 6-level hierarchical model of efficacy described by Fryback and Thornbury. (author)

    Traumatic abdominal wall hernias (TAWHs) are rare. Their diagnosis is mostly clinical and can be overlooked in the setting of trauma and distracting injuries or they can be misinterpreted as parietal hematomas. Associated lesions can influence decision making regarding time of operation and surgical technique. Our case highlights the management of a high-energy TAWH that associates a small bowel traumatic lesion. Surgical repair of TAWHs should follow general hernia repair principles. Further exploration of surgical options is necessary for a consensus to be reached. PMID:25972687

    Full Text Available Angiomatous malformation is the most common vascular abnormality, accounting for 30-40% cases of obscure GI bleeding from small bowel. Surgical resection is the treatment of choice in severe or recurrent hemorrhage requiring multiple blood transfusions. However, the diffuse nature of the lesions poses a challenge to localize them accurately preoperatively, for exact resection. We present a case in which we have used selective mesenteric angiography with selective cannulation and exact localization of the lesion by injecting dye such as methylene blue, indigo carmine, and fluorescein, to localize the angiomatous malformation before surgical resection and also to determine the exact resection to be done.

    Small bowel motility analyses using magnetic resonance imaging (MRI) could reduce current invasive techniques in animal studies and comply with the 'three Rs' rule for human animal experimentation. Thus we investigated the feasibility of in vivo small bowel motility analyses in mice using dynamic MRI acquisitions. All experimental procedures were approved by the institutional animal care committee. Six C57BL/6 mice underwent MRI without additional preparation after isoflurane anaesthetization in the prone position on a 4.7 T small animal imager equipped with a linear polarized hydrogen birdcage whole-body mouse coil. Motility was assessed using a true fast imaging in a steady precession sequence in the coronal orientation (acquisition time per slice 512?ms, in-plane resolution 234?×?234?µm, matrix size 128?×?128, slice thickness 1?mm) over 30?s corresponding to 60 acquisitions. Motility was manually assessed measuring the small bowel diameter change over time. The resulting motility curves were analysed for the following parameters: contraction frequency per minute (cpm), maximal contraction amplitude (maximum to minimum [mm]), luminal diameter (mm) and luminal occlusion rate. Small bowel motility quantification was found to be possible in all animals with a mean small bowel contraction frequency of 10.67?cpm (SD?±?3.84), a mean amplitude of the contractions of 1.33?mm (SD?±?0.43) and a mean luminal diameter of 1.37?mm (SD?±?0.42). The mean luminal occlusion rate was 1.044 (SD?±?0.45%/100). The mean duration needed for a single motility assessment was 185?s (SD?±?54.02). Thus our study demonstrated the feasibility of an easy and time-sparing functional assessment for in vivo small bowel motility analyses in mice. This could improve the development of small animal models of intestinal diseases and provide a method similar to clinical MR examinations that is in concordance with the 'three Rs' for humane animal experimentation.

  3. Gradient-enhanced volume rendering: an image processing strategy to facilitate whole small bowel imaging with MRI

    International Nuclear Information System (INIS)

    MRI of the small bowel with positive contrast from orally administered contrast agent is a promising non-invasive imaging method. The aim of our study was to introduce small bowel MRI in a display format that clinicians are accustomed to and that maximizes the amount of information visualized on a single image. Twelve healthy volunteers, median age 32 years (range 18-49 years) participated in the study. A mixture of 20 ml Gd-DOTA (Dotarem), 0.8 g/kg body weight psyllium fibre (Metamucil) and 1.2 l water were sequentially administered over a period of 4 h. Imaging was performed on a 1.5 T unit (Philips Gyroscan, Intera). Fat-saturated, 3D, gradient echo imaging was performed while the patient was in apnea (30 s). Bowel motion was reduced with 40 mg intravenously administered scopolamine (Buscopan). A 3D, gradient-enhanced, volume rendering technique was applied to the 3D data sets. Standard projections [left anterior oblique (LAO), right anterior oblique (RAO), supine and prone] resembling conventional enteroclysis were successfully generated within fewer than 10 min processing time. Reconstructions were reproducible and provided an entire overview of the small bowel. In addition thin-slab volume rendering allowed an overlap-free display of individual structures. Positive contrast from orally administered contrast agent, combined with a gradient enhanced volume rendering method, allows the reconstruction of the small bowel in a pattern resembling conventional double-contrast enteroclysis. Segmental display without overlay is possible. (orig.)

  5. Closed loop obstructions of the small bowel: role of Computed Tomography

    International Nuclear Information System (INIS)

    Small bowel obstructions can be distinguished into more simple and closed loop obstructions. The latter is a more severe condition which is often complicated by strangulation with vascular impairment, edema and intramural and mesenteric hemorrhage. Consequent arterial insufficiency rapidly leads to ischemia, infarction and necrosis. The radiologist plays a role in the early recognition of the closed loop obstruction and of any sign of strangulation. The role of CT in the diagnosis and workup of patients with suspected intestinal occlusion has been analyzed in the literature with reported 63% sensitivity, 78% specificity and 66% accuracy. CT is also capable of revealing the causes of occlusion in 73-95% of cases. The above CT signs allow to identify closed loop obstruction and also small bowel strangulation, thus supplying a valuable contribution to diagnosis and accurate preoperative evaluation. The conclusion is that CT can accurately demonstrate the presence of closed loop obstruction and can be the technique of choice in patients in whom obstruction is associated with clinical signs suggestive of strangulation

  6. The stepchild of intestinal diagnostics. Evaluation of radiological methods to diagnose leiomyomas of the small bowel

    International Nuclear Information System (INIS)

    Purpose: Various radiological methods to diagnose small bowel neoplasmas and problems of differential diagnosis specially considerating leiomyomas are discussed. Patients and methods: Two patients with leiomyoma of the ileum underwent enteroclysis, computed tomography of the abdomen, intra-arterial DSA and colour Doppler sonography. Another patient with leiomyosarcoma just underwent CT of the abdomen with CT-guided biopsy. Results: Due to the homogenous density and the smooth surface of the tumors in computed tomography and respectively enteroclysis and the presentation of the tumor vascularisation in the angiography and Colour Doppler sonography in both patients a leiomyoma of the small bowel was diagnosed. Postoperatively this diagnosis was histologically confirmed. The CT-findings of the patient with leiomyosarcoma were not suspicious of a malignant tumor. Conclusion: Radiologically it is not possible to determine the dignity of smooth muscle cell tumors safely. That is the reason why the diagnosis has to be achieved operatively. But the histopathological diagnosis based on the mitotic rate may be difficult. Therefore the after care has to be carried out thoroughly. (orig.)

    Small bowel accounts for only 0.5% of cancer cases in the US but incidence rates have been rising at 2.4% per year over the past decade. One-third of these are adenocarcinomas but little is known about their molecular pathology and no molecular markers are available for clinical use. Using a retrospective 28 patient matched normal-tumor cohort, next-generation sequencing, gene expression arrays and CpG methylation arrays were used for molecular profiling. Next-generation sequencing identified novel mutations in IDH1, CDH1, KIT, FGFR2, FLT3, NPM1, PTEN, MET, AKT1, RET, NOTCH1 and ERBB4. Array data revealed 17% of CpGs and 5% of RNA transcripts assayed to be differentially methylated and expressed respectively (p < 0.01). Merging gene expression and DNA methylation data revealed CHN2 as consistently hypermethylated and downregulated in this disease (Spearman -0.71, p < 0.001). Mutations in TP53 which were found in more than half of the cohort (15/28) and Kazald1 hypomethylation were both were indicative of poor survival (p = 0.03, HR = 3.2 and p = 0.01, HR = 4.9 respectively). By integrating high-throughput mutational, gene expression and DNA methylation data, this study reveals for the first time the distinct molecular profile of small bowel adenocarcinoma and highlights potential clinically exploitable markers.

  8. Effect of acetylcysteine on adaptation of intestinal smooth muscle after small bowel bypass

    International Nuclear Information System (INIS)

    The authors have postulated that the adaptive changes in function and structure of bypassed segments of small bowel are due in part to the change in intestinal contents following operation. The purpose of these experiments was to determine if a mucolytic agent could alter the adaptation. Rats were anesthetized and a 70% jejunoileal bypass was performed. The bypassed segments then were perfused with either saline or acetylcysteine for 3-12 days. Then, either intestinal transit was determined using Cr-51, or segments were taken for morphometric analysis. Transit, as assessed by the geometric center, was increased 32% by acetylcysteine treatment. Treatment also caused a decrease in hypertrophy of the muscularis. Muscle wet weight, muscle cross-sectional area, and muscle layer thickness all were significantly less in those animals infused with acetyl-cysteine. No decreases in hypertrophy were seen in the in-continuity segments. These data indicate that alterations in intestinal content can affect the course of adaptation of intestinal muscle in response to small bowel bypass

    Full Text Available AIM: To investigate the relationship between low-dose aspirin-induced small bowel mucosal damage and blood flow, and the effect of rebamipide.METHODS: Ten healthy volunteers were enrolled in this study. The subjects were divided into two groups: a placebo group given low-dose aspirin plus placebo and a rebamipide group given low-dose aspirin plus rebamipide for a period of 14 d. Capsule endoscopy and contrast-enhanced ultrasonography were performed before and after administration of drugs. Areas under the curves and peak value of time-intensity curve were calculated.RESULTS: Absolute differences in areas under the curves were -1102.5 (95% CI: -1980.3 to -224.7, P = 0.0194 in the placebo group and -152.7 (95% CI: -1604.2 to 641.6, P = 0.8172 in the rebamipide group. Peak values of time intensity curves were -148.0 (95% CI: -269.4 to -26.2, P = 0.0225 in the placebo group and 28.3 (95% CI: -269.0 to 325.6, P = 0.8343 in the rebamipide group. Capsule endoscopy showed mucosal breaks only in the placebo group.CONCLUSION: Short-term administration of low-dose aspirin is associated with small bowel injuries and blood flow.

    2010-04-01

    Full Text Available Well-differentiated endocrine carcinomas of the small bowel are fairly rare neoplasms that present many clinical challenges. They secrete peptides and neuroamines that may cause carcinoid syndrome. However, many are clinically silent until late presentation with major effects. Initial treatment aims to control carcinoid syndrome with somatostatin analogs. Even if there is metastatic spread, surgical resection of the primitive tumor should be discussed in cases of retractile mesenteritis, small bowel ischemia or subocclusive syndrome in order to avoid any acute complication, in particular at the beginning of somatostatin analog treatment. The choice of treatment depends on the symptoms, general health of the patient, tumor burden, degree of uptake of radionuclide, histological features of the tumor, and tumor growth. Management strategies include surgery for cure (which is rarely achieved or for cytoreduction, radiological interventions (transarterial embolization or radiofrequency ablation, and chemotherapy (interferon and somatostatin analogs. New biological agent and radionuclide targeted therapies are under investigation. Diffuse and non-evolving lesions should also be simply monitored. Finally, it has to be emphasized that it is of the utmost importance to enroll these patients with a rare disease in prospective clinical trials assessing new therapeutic strategies.

    Full Text Available AIM: To study the small bowel (SB mucosa on biopsy in cirrhotic patients with portal hypertension and in non-cirrhotic controls and grade findings according to the Marsh criteria.METHODS: We prospectively enrolled 51 consecutive patients undergoing an upper endoscopy for their routine medical care. Twenty five patients with cirrhosis and portal hypertension were compared to 26 controls. We obtained coeliac serology and multiple upper small bowel biopsies on all 51 patients. A GI pathologist interpreted biopsies and graded findings according to the Marsh criteria. We assessed equivalence in Marsh grade between cirrhotic and non-cirrhotic controls using the Mann-Whitney test for equivalence.RESULTS: Gender, ethnicity and age were similar between both groups. Marsh grades were equivalent between the groups. Grade of 0 was present in 96% and grade of 1 was present in 4% of both groups and there was no villus atrophy or decrease in villus/crypt ratio in patients with portal hypertension.CONCLUSION: This study provides evidence for the lack of villus atrophy in patients with cirrhosis and portal hypertension, and supports the continuous reliance on the Marsh criteria when the diagnosis of coeliac disease is to be made in the presence of cirrhosis.

    Objective: the present study was aimed at demonstrating the value of computed tomography enterography (CT enterography) and how this imaging method can be useful in the diagnostic elucidation and assessment of patients with small bowel diseases. Materials and methods: retrospective evaluation of 35 patients submitted to CT enterography in a 16-row multidetector CT equipment from May/2008 to March/2009. All the patients received intravenous and neutral oral iodinated contrast agents (polyethylene glycol). Main indications were: Crohn's disease, diarrhea of undetermined origin and suspicion of neoplasia. Results: a good correlation was observed between CT enterography findings and clinical, laboratory and endoscopic data related to the disease activity in patients with Crohn's disease. In 15 cases alterations compatible with Crohn's disease were identified, nine of them suggesting disease activity. A diagnosis was achieved in the majority of the patients with diarrhea. Carcinoid tumors were identified in two patients. Conclusion: CT enterography is a simple and effective method in the evaluation of inflammatory/neoplastic small bowel diseases, particularly in cases of Crohn's disease, indicating disease activity. One of the main advantages of this method is the possibility of evaluating associated mesenteric and extraintestinal alterations (author)

  13. Efficacy of a belly board device with CT-simulation in reducing small bowel volume within pelvic irradiation fields

    International Nuclear Information System (INIS)

    Purpose/Objective: Acute and chronic small bowel toxicity associated with pelvic irradiation limits dose escalation for both chemotherapy and radiotherapy for rectal cancer. Various surgical and technical maneuvers including compression and belly board devices (BBD) have been used to reduce small bowel volume in treatment fields. However, quantitative dose volume advantages of such methods have not been reported. In this study, the efficacy of BBD with CT-simulation is presented with dose-volume histogram (DVH) analyses for rectal cancer. Methods and Materials: Twelve consecutive patients referred to our department with rectal cancer were included in this study. Patients were given oral contrast 1.5 h prior to scanning and instructed not to empty their bladder during the procedure. The initial CT scan without BBD was taken in the prone position with an immobilization cast. A second CT study was performed with a commercially available BBD consisting of an 18-cm thick hard sponge with an adjustable opening (maximum 42 x 42 cm2). All patients were positioned prone over the BBD so that the opening was above the treatment volume and usually extended from the diaphragm to the bottom of the fourth lumbar spine. Image fusion between both sets of CT scans (with and without BBD) was performed using common bony landmarks to maintain the same target volume. The critical structures including small bowel and bladder were delineated on each slice for DVH analysis. On each study, a three-field optimized plan with conformal blocks in beams-eye-view was generated for volumetric analysis. The DVHs with and without BBD were evaluated for each patient. Results: The median age and body weight of 12 patients (4 females and 8 males) were 57.5 years and 82.7 kg, respectively. The changes in posterior-anterior (PA) and lateral separation with and without BBD at central axis slices were analyzed. The changes in lateral separation were minimal (<0.8 cm); however, the PA separation was reduced by 11.3 ± 3.3% when BBD was used. The reduction in PA separation was directly related to the reduction is small bowel volume. The small bowel volume was significantly reduced with a median reduction of 70% (range 10-100%) compared to the small bowel volume without BBD. The small bowel volume reduction did not correlate either with body weight, age, gender, or sequence of radiation treatment with surgery (pre-op vs. post-op). The DVH analysis of small bowel with BBD showed significant volume reduction at each dose level. For 50% patients, the DVH analysis demonstrated an increase in bladder volume with BBD. All patients treated with the BBD completed their treatment without any break and without significant acute gastrointestinal or genitourinary toxicity. Conclusions: For rectal cancers, small bowel is the dose-limiting structure for acute and chronic toxicity. The use of the BBD should improve the tolerance of aggressive combined modality treatment by reducing the small bowel volume within the pelvis compared to the prone position alone. The BBD provides an easy, economical, comfortable, and noninvasive technique to displace small bowel from pelvic treatment fields. The small bowel volume is dramatically reduced at each dose level. The volume reduction does not correlate with gender, age, weight, pelvic separation, and sequence of radiation treatment vs. surgery

    Full Text Available Abstract Background To report a 45 year old lady presenting with proximal jejunal gangrene due to invasive Aspergillosis. The patient was undergoing adjuvant chemotherapy for advance carcinoma of breast (Stage IV. Methods The patient was referred to our surgical emergency for acute abdominal symptoms for 6 hours. Histopathology revealed bowel wall necrosis and vascular invasion by Aspergillus Fumigatus. Postoperative recovery was uneventful and the patient received Amphotericin-B (1 mg/kg/day for invasive aspergillosis. Invasive pulmonary aspergillosis was confirmed by isolating Aspergillus Fumigatus from bronchoalveolar lavage and by a positive circulating galactomannan test (ELISA Assay. Results Detailed history revealed dry cough and two episodes of haemoptesis for 2 weeks. Haemogram and counts revealed anemia and neutropenia. Plain X – ray of the abdomen showed multiple air fluid levels and ultrasound of the abdomen revealed distended bowel loops. On exploration small bowel was found to be gangrenous. The patient was successfully managed by supportive treatment and conventional intravenous Amphotericin-B for 2 weeks. The lady was discharged one week after completion of antifungal therapy and one month later she underwent toilet mastectomy. The lady came to follow up for 1 year and she is currently under hormone therapy. Conclusion With the emergence of new and powerful immunosuppressive, anticancer drugs and potent antibiotics the survival of transplant and critically ill patients has remarkably increased but it has shown a significant rise in the incidence of invasive opportunistic fungal infections. We conclude hat the diagnosis of invasive gastrointestinal aspergillosis may be considered in a neutropenic patient with acute abdominal symptoms.

Nuestro objetivo es presentar la experiencia de nuestro centro en el tratamiento laparoscópico de la OIB. Material y Métodos: Estudio retrospectivo incluyendo pacientes con el diagnóstico de OIB que fueron sometidos a cirugía laparoscópica en nuestro centro, entre junio de 2003 y abril de 2013. Análisis de variables demográficas, quirúrgicas y resultados obtenidos en términos de tasa de conversión, tiempo operatorio, tiempo de realimentación y estadía hospitalaria. Análisis estadístico con pruebas no paramétricas. Resultados: Serie de 38 pacientes, edad promedio: 51 ± 16 años, 47% sexo masculino. 53% con antecedente de cirugía abdominal previa. Resolución completa por laparoscopía fue posible en 31 pacientes (82%), con 7 conversiones a cirugía abierta. La mediana de tiempo operatorio fue de 60 m (25-180), la mediana de tiempo a la realimentación fue de 24 h (24-192) y la mediana de estadía hospitalaria de 4 (2-52) días. Dos pacientes requirieron reoperaciones durante su hospitalización; uno debido a obstrucción intestinal persistente y otro debido a colitis isquémica. No se presentaron otras complicaciones ni mortalidad en esta serie. Conclusiones: El abordaje laparoscópico en OIB es factible de realizar en pacientes seleccionados, logrando buenos resultados en caso de resolución completa por laparoscopía. Pacientes sin cirugías abdominales previas son buenos candidatos para un abordaje laparoscópico inicial. Abstract in english Background: Treatment options for adhesive small bowel obstruction (ASBO) involve conservative and surgical management, traditionally through open adhesiolysis. Laparoscopic approach has been performed in recent years; however, limited data exist on its safety and results vary considerably. Our aim [...] is to report our experience of laparoscopic treatment for ASBO. Methods: Retrospective study including patients admitted with the diagnosis of adhesive small bowel obstruction and that were submitted to laparoscopic exploration, between June 2003 and April 2013. We analyzed demographic, surgical variables and outcomes in terms of conversion rate, operative time, re-feeding time and length of stay. Non-parametric tests were used for statistical analysis. Results: Series of 38 patients submitted to laparoscopic exploration, mean age: 51 ± 16 years, 47% male. 53% had prior intra-abdominal surgeries. Laparoscopic resolution of bowel obstruction was possible in 31 patients (82%), with 7 conversions to open surgery. Median operative time was 60 (25-180) minutes, median re-feeding time was 24 (24-192) hours and median length of stay was 4 (2-52) days. Two patients required re-intervention during their hospital stay, one due to persistent bowel obstruction and one due to ischemic colitis. There were no other complications or mortality. Conclusions: Laparoscopy in adhesive small bowel obstruction was a feasible approach in this series, with good results when laparoscopic resolution is achieved. Patients with no prior surgeries seem to be good candidates for this approach.

  16. Computed tomography to detect body packing: an unusual cause of small bowel obstruction

    International Nuclear Information System (INIS)

    Concealment of illicit drugs within the alimentary tract is now an established method used by both smugglers and traffickers to evade detection by authorities. Those who ingest wrapped packets of drugs to transport them across international borders are known as 'body packers,' whereas those who ingest packages of drugs upon an unexpected encounter with law enforcement agents are known as 'body stuffers' or 'quick swallowers. Although most of these individuals require no medical care, acute drug toxicity (from inadvertent leaking of contents or rupture of the drug packet) and bowel obstruction are recognized hazards of drug packet ingestion. The detection of these packets is a challenge to custom officials and police interested in preventing the import and trafficking of illegal drugs, as well as to physicians who have to treat individuals who have ingested them. We report a case of a 38-year-old intravenous drug abuser who presented with an acute small bowel obstruction secondary to an impacted intraluminal heroin balloon in the mid jejunum. The value of computed tomography (CT) in the patient's diagnostic evaluation is highlighted. (author)

  18. Capsule endoscopy : a cause of late small bowel obstruction and perforation

    DEFF Research Database (Denmark)

    Skovsen, Anders Peter; Burcharth, Jakob

    2013-01-01

    Case Report. A 71-year-old man was admitted to the department of gastroenterology with diffuse abdominal pain. Through the previous 12 months, the patient had experienced episodes of vomiting and watery diarrhea of increasing intensity as well as weight loss. The patient was evaluated with ultrasound, MRI, and subsequently a capsule endoscopy. Six months later, the patient presented, and an abdominal CT-scan showed mechanical small bowel obstruction with suspicion of metallic foreign body and perforation. Laparotomy showed perforation, stenosis, and foreign body, approximately 5?cm from the ileocecal valve. A right hemicolectomy and distal ileectomy (60?cm) with an ileostomy were performed. On further inspection of resection, a capsule endoscope was found impacted in a stenosis. The ileostomy was later reversed without complications. Conclusion. It is important to be aware of the possibility of capsule retention, especially in patients with known or suspected Crohn's disease, due to the propensity of Crohn's disease to form stenosis of the bowel. In cases where a stenosis is suspected, it is warranted to perform a patency capsule swallow before subjecting the patient to a capsule endoscopy.

  19. Diet, ageing and genetic factors in the pathogenesis of diverticular disease

    2009-05-01

    Full Text Available Diverticular disease (DD is an age-related disorder of the large bowel which may affect half of the population over the age of 65 in the UK. This high prevalence ranks it as one of the most common bowel disorders in western nations. The majority of patients remain asymptomatic but there are associated life-threatening co-morbidities, which, given the large numbers of people with DD, translates into a considerable number of deaths per annum. Despite this public health burden, relatively little seems to be known about either the mechanisms of development or causality. In the 1970s, a model of DD formulated the concept that diverticula occur as a consequence of pressure-induced damage to the colon wall amongst those with a low intake of dietary fiber. In this review, we have examined the evidence regarding the influence of ageing, diet, inflammation and genetics on DD development. We argue that the evidence supporting the barotrauma hypothesis is largely anecdotal. We have also identified several gaps in the knowledge base which need to be filled before we can complete a model for the etiology of diverticular disease.

  20. Efficacy of belly board device with CT-simulation in reducing small bowel volume within pelvic irradiation fields

    International Nuclear Information System (INIS)

    Purpose/Objective: Acute and chronic small bowel toxicity associated with pelvic irradiation limits dose escalation with both chemotherapy and radiotherapy (RT) for rectal cancer. Various surgical and technical maneuvers including compression and belly board devices (BBD) have been used to reduce small bowel volume in treatment fields. However, quantitative dose volume advantages of such methods have not been reported. In this study, the efficacy of BBD with CT-simulation is presented with dose-volume histogram (DVH) analyses for rectal cancer. Materials and Methods: Five consecutive patients referred to our department with rectal cancer (2 preoperative, 3 postoperative RT) were included in this study. Each patient was asked to drink 450 cc of oral contrast 60 minutes prior to scanning and an additional 450 cc 15 minutes before CT-simulation. Patients were advised not to void for at least 2 hours prior to CT-simulation for optimal bladder distention. Patients were initially scanned in the prone position with alpha-cradle immobilization. A second CT study was conducted with a commercially available BBD which is made up of a hard sponge 18 cm thick with an adjustable opening (maximum 40x40 cm2). Patients were positioned prone over the BBD opening which was placed between the diaphragm and fourth lumbar spine of the patient. With the spiral CT-scanner, the entire scanning process was accomplished within 30 minutes. Image fusion between both sets of CT scans (with and without BBD) was performed using three common bony landmarks. The critical structures including small bowel, bladder, and target volumes were delineated on each slice for DVH calculation. The target volumes were maintained in both studies. On each study, a three field optimized plan with conformal blocks in beams-eye-view was generated for volumetric analysis. The DVHs with and without BBD were evaluated for each patient. Results: The average weight of the patients was 80.3±10.1 kg. The central axis anterior-posterior (AP) and lateral separation with and without BBD were measured. The changes in lateral separation were minimal (<0.5 cm), however the changes in AP separation were reduced by 2.5±0.8 cm when BBD was used. With the BBD, the small bowel volume was significantly reduced with a mean reduction of 50.3% (range 34%-71%). The volume reduction was not correlated with body weight or sequence of RT (preop vs. post op). The DVH analysis of small bowel with and without BBD is shown in Table 1 for limited dose levels. The reduction of small bowel volume can be seen at each dose level. A representative DVH of small bowel with and without BBD is shown in Fig. 1. Figure 2 shows the ratio of volumes with and without BBD at various dose levels for each patients. A ratio below 1.0 represents a reduction of small bowel volume. A slight increase in bladder dose volume with BBD was also noted in a few patients. Conclusions: The belly board provides an easy technique to displace small bowel from pelvic RT treatment fields. The small bowel volume reduction is significant and is not related to body weight, separation, and sequence of RT with surgery. The volume reduction is appreciable at each dose level with a maximum of 70%. For some patients, the bladder dose volume may be increased moderately. Further study of the clinical efficacy of the BBD with specific attention to acute and chronic bowel complications and tolerances of full dose chemoradiation will continue

    Vehicle collisions represent more than 75% of mechanism of blunt abdominal trauma. In spite of the incomparable improvement of car safety devices, recent studies pointed out that the air bags might cause injuries, specially when it is not associated with seatbelt. In fact, some studies pointed out that crash victims using air bags alone have increased injury severity, hospitalisations, thoracoabdominal procedure, and rehabilitation. Some of the most frequently injured organs reported from air bag deployment are the liver (38%), the spleen (23%) and digestive system (17%). Injury of the hollow viscera are far less common. In particular, blunt abdominal trauma resulting in small bowel perforation is an infrequent lesion. These injuries are difficult to diagnose because specific signs are poor and a delay in treatment increases mortality and morbidity of the patients. We describe a case of thoracoabdominal trauma that occurred during a head-on collision after an air bag deployment without seatbelt use. PMID:19505417

    Full Text Available Gastrointestinal involvement of endometriosis has been found in 3%-37% of menstruating women and exclusive localization on the ileum is very rare (1%-7%. Endometriosis of the distal ileum is an infrequent cause of intestinal obstruction, ranging from 7% to 23% of all cases with intestinal involvement. We report a case in which endometrial infiltration of the small bowel caused acute obstruction requiring emergency surgery, in a woman whose symptoms were not related to menses. Histology of the resected specimen showed that endometriosis was mainly prevalent in the muscularis propria and submucosa and that the mucosa was not ulcerated but had inflammation and glandular alteration. Endometrial lymph node involvement, with a cystic glandular pattern was also detected.

  3. Seatbelt injury causing small bowel devascularisation: case series and review of the literature.

    The use of seatbelts has increased significantly in the last twenty years, leading to a decrease in mortality from road traffic accidents (RTA). However, this increase in seatbelt use has also led to a change in the spectrum of injuries from RTA; abdominal injuries, particularly intestinal injuries have dramatically increased with the routine use of seatbelts. Such intestinal injuries frequently result from improper placement of the "lap belt". We present 3 cases in which passengers wearing a seatbelt sustained significant devascularisation injuries to the small bowel requiring emergency surgical intervention. A high index of suspicion is crucial in such cases to prevent delays in diagnosis that can lead to severe complications and adverse outcomes. It is evident that while advocating seatbelt use, the importance of education in correct seatbelt placement should also be a focus of public health strategies to reduce RTA morbidity and mortality.

    Full Text Available Meconium ileus is one of important causes of neonatal intestinal obstruction. Many patients respond well to nonsurgical management with enemas, however, few patients may develop complications in the postnatal period thus requiring urgent operation. A 2 day old newborn presented with clinical features of intestinal obstruction. There was a suspicion of meconium ileus. Contrast x-ray with gastrografin enema was suggestive of unused colon with beaded appearance. Patient had to be surgery as repeated enemas did not improve the condition and progressive abdominal distension occurred. At exploration twist of the dilated, meconium filled loop of small bowel found. De-twisting of the volvulus done and Bishop Koop ileostomy fashioned. Patient made an uneventful recovery. Stoma was closed six months later.

    Full Text Available Stromal tumors of the gastrointestinal tract (gists represent relatively rare lesions that arise from connective tissue elements located along the entire length of the gut. They were initially identified by immunohistochemical investigation, proving their origin from nondifferentiated mesenchymal cells. Only a minority of this lesions, mainly those confined to the esophagus and rectum, have been shown to correspond to mature, well-differentiated types of neoplasms such as leiomyoma or leiomyosarcoma. The majority of gists corresponds to a heterogeneous group of lesions that have as their common denominator an immature proliferation of epithelioid or spindle cells arising from its muscle layers, or between them, showing partial or incomplete myoide, neural, ganglionic, or mixed features of differentiation. This case report intends to show a gist of small bowel in a male, 46 years old, with a two-year of evolution.

    BACKGROUND: Ganglioneuroma is a rare tumour of neural crest origin, which arises from maturation of a neuroblastoma. While previously considered to be non-functioning, they are now known to be frequently endocrinologically active. AIMS AND METHODS: We report a case of a massive retroperitoneal ganglioneuroma presenting with small bowel obstruction in an adult, 18 years after initial diagnosis. Urinary dopamine levels were elevated, but other catecholamines were within normal limits. This is the first report in the English-language literature of a retroperitoneal ganglioneuroma presenting with or causing intestinal obstruction. We also review the metabolic, radiological, and histological features of these tumours. Relevant publications were identified from a Medline search using the MeSH headings \\'ganglioneuroma\\

    Full Text Available BACKGROUND: Malignant melanomas often cause intestinal metastasis.Metastases of malignant melanoma are the most common secondary tumors of the gastrointestinal tract.The incidence of intestinal metastasis of malignant melanomas is 1.5-4.4% in clinical studies, reaching upto 35.6-58% in necroptic studies. AIM: We present a clinical case of multiple metastases to the smallbowel with point of departure right retroauricular malignant melanoma. METHODS: Patient T.I., 76years old, is admitted in our clinic with occlusion clinical features installed by approximately 2-3 days.From anamnesis we retain a subocclusion clinical feature installed by approximately 1-2 months, withgradual overheating. On clinical examination a right supraclavicular tumoral formation is found, sizing2.5-3cm, suggestive for malignant melanoma. The abdominal CT shows multiple tumoral formations inthe small bowel, with no other secondary determinations in the other organs. RESULTS: Intraoperatorywe have found six secondary lesions on the jejunum, two on the ileum and two mesenteric metastases. Itwas done partial enterectomy on the jejunal segment with latero-lateral jejuno-jejunal anastomoses andpartial enterectomy on the ileum segment with ileostoma. Postoperatory short-term outcome, at six andtwelve months was favorable. CONCLUSIONS: Small bowel metastases of malignant melanoma is thefirst suspected diagnosis in a patient with oclusive/suboclusive intestinal manifestations and clinicallesions suggestive of malignant melanoma. The patient presentes for acute complications (occlusion,intestinal perforation or chronic complications (chronic digestive bleeding, anemic syndrome. Oftennon-specific symptoms are present, which delay the diagnosis. Surgical treatment is the first therapeuticoption, even in case of multiple secondary determinations.

    2009-05-01

    Full Text Available A total of 65-84% of patients with irritable bowel syndrome (IBS presents with small intestinal bacterial overgrowth (SIBO. SIBO is defined as the presence of more than 105 cfu/ml of colonic type bacteria in the lumen of the small bowel. It is more common in patients with IBS and predominant bloating and diarrhea. Based on the implication of SIBO in the pathogenesis of IBS, six trials have been conducted and analyzed in this review aiming to define a role of rifaximin for the management of IBS. Rifaximin is an orally administered antimicrobial with limited systemic absorption and considerable potency against bacteria implicated in SIBO. In two trials patients with SIBO irrespective of the presence of IBS were enrolled. A positive effect of rifaximin was denoted in the eradication of SIBO in both.One double-blind, prospective randomized trial over placebo in patients with IBS denoted a substantial improvement of the global assessment of patients after treatment with rifaximin. Benefit remained for 10 weeks after stop of treatment. A major benefit was disclosed for bloating. Another three prospective randomized trials have been conducted in patients with both IBS and SIBO. Rifaximin significantly eradicated SIBO and improved bloating.These findings led the Task Force for IBS of the American College of Gastroenterology to appoint a grade of evidence of 1B for the administration of rifaximin in the management of IBS. The proposed oral regimen is 400 mg three times daily for 10 days. However, results of large Phase III trials are mandatory.

    Full Text Available Background: Supra-Transumbilical Laparotomy (STL has been used in paediatric surgery for a broad spectrum of abdominal procedures. We report our experience with STL approach for small bowel atresia repair in newborns and review previous published series on the topic. Patients and Methods: Fourteen patients with small bowel atresia were treated via STL approach at our Institution over a 5-year period and their charts were retrospectively reviewed. Results: STL procedure was performed at mean age of 3.1 day. No malrotation disorders were detected with pre-operative contrast enema. Eight patients (54.1% presented jejunal atresia, five (35.7% ileal atresia, and one (7.1% multiple ileal and jejunal atresias. Standard repair with primary end-to-back anastomosis was performed in all but one patient. In the newborn with multiple atresia, STL incision was converted in supra-umbilical transverse incision due to difficulty of exposition. After surgery, one patient developed anastomotic stricture, and another developed occlusion due to adhesions: Both infants required second laparotomy. No infections of the umbilical site were recorded, and cosmetic results were excellent in all patients. Conclusions: Increasing evidence suggests that STL approach for small bowel atresia is feasible, safe and provides adequate exposure for small bowel atresia surgery. When malrotation and colonic/multiple atresia are pre-operatively ruled out, STL procedure can be choosen as first approach.

    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.

    Our aim was to assess the diagnostic performance in determining strangulation in small bowel obstruction (SBO) for five CT findings commonly considered in published small bowel obstruction (SBO) management guidelines. Medical databases were searched for ''bowel obstruction'', ''computed tomography'', ''strangulation'', and related terms. Two reviewers independently selected articles for CT findings investigated with surgical or histological reference standards for strangulation. Bivariate random-effects meta-analytical methods were used. A total of 768 patients, including 205 with strangulation from nine studies, were evaluated. The reduced bowel wall enhancement CT sign had the highest specificity (95 %, CI 75-99), with a positive LR of 11.07 (2.27-53.88) and DOR of 22.86 (4.99-104.61). The mesenteric fluid sign had the highest sensitivity (89 %, CI 75-96) with a negative LR of 0.16 (0.07-0.39) and a DOR of 13.9 (5.73-33.75). The bowel wall thickness had a sensitivity of 48 % (CI 41-54), a specificity of 83 % (CI 74-89), a positive LR of 2.84 (1.83-4.41) and a negative LR of 0.62 (0.53-0.72). The other CT findings had lower diagnostic performance. Two CT findings should be used in clinical practice: reduced enhanced bowel wall is highly predictive of ischemia, and absence of mesenteric fluid is a reliable finding to rule out strangulation.

    Full Text Available Abstract Background The incidence of colonic diverticular disease varies with national origin, cultural background and diet. The frequency of this disease increases with advancing age. Right-sided diverticular disease is uncommon and reported to occur in 1-2% of surgical specimens in European and American series. In contrast the disease is more prevalent and reported in 43-50% of specimens in Asian series. Various lines of evidence suggest this variation may represent hereditary differences. The aim of the study is to report all cases of right sided diverticular disease underwent surgical resection or identified during pathological examination of right hemicoloectomy specimens Methods A retrospective review of all surgical specimens with right sided colonic diverticular disease selected from a larger database of all colonic diverticulosis and diverticulitis surgical specimen reported between January 1993 and December 2010 at the Pathology Department McMaster University Medical Centre Canada. The clinical and pathological features of these cases were reviewed Results The review identified 15 cases of right colon diverticulosis. The clinical diagnoses of these cases were appendicitis, diverticulitis or adenocarcinoma. Eight cases of single congenital perforated diverticuli were identified and seven cases were incidental multiple acquired diverticuli found in specimen resected for right side colonic carcinomas/large adenomas. Laparotomy or laparoscopic assisted haemicolectomies were done for all cases. Pathological examination showed caecal wall thickening with inflammation associated with perforated diverticuli. Histology confirmed true solitary diverticuli that exhibited in two cases thick walled vessels in the submucosa and muscular layer indicating vascular malformation/angiodysplasia. Acquired diverticuli tend to be multiple and are mostly seen in specimens resected for neoplastic right colon diseases. Conclusion Single true diverticular disease of the right colon is usually of congenital type and affects younger age group and may be associated with angiodysplasia in some cases. Multiple false diverticuli are more seen in association with caecal carcinoma or large adenomas. These are usually asymptomatic and are more seen in older patients. However this study dose not reflects the true incidence of the disease in the general population.

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

    Full Text Available Abstract Background Small intestinal bacterial overgrowth (SIBO is a condition in which excessive levels of bacteria, mainly the colonic-type species are present in the small intestine. Recent data suggest that SIBO may contribute to the pathophysiology of Irritable bowel syndrome (IBS. The purpose of this study was to identify potential predictors of SIBO in patients with IBS. Methods Adults with IBS based on Rome II criteria who had predominance of bloating and flatulence underwent a glucose breath test (GBT to determine the presence of SIBO. Breath samples were obtained at baseline and at 30, 45, 60, 75 and 90 minutes after ingestion of 50 g of glucose dissolved in 150 mL of water. Results of the glucose breath test, which measures hydrogen and methane levels in the breath, were considered positive for SIBO if 1 the hydrogen or methane peak was >20 ppm when the baseline was Results Ninety-eight patients were identified who underwent a GBT (mean age, 49 y; 78% female. Thirty-five patients (36% had a positive GBT result suggestive of SIBO. A positive GBT result was more likely in patients >55 years of age (odds ratio [OR], 3.6; 95% confidence interval [CI], 1.4-9.0 and in females (OR, 4.0; 95% CI, 1.1-14.5. Hydrogen was detected more frequently in patients with diarrhea-predominant IBS (OR, 8; 95% CI, 1.4-45, and methane was the main gas detected in patients with constipation-predominant IBS (OR, 8; 95% CI, 1.3-44. There was no significant correlation between the presence of SIBO and the predominant bowel pattern or concurrent use of tegaserod, proton pump inhibitors, or opiate analgesics. Conclusions Small intestinal bacterial overgrowth was present in a sizeable percentage of patients with IBS with predominance of bloating and flatulence. Older age and female sex were predictors of SIBO in patients with IBS. Identification of possible predictors of SIBO in patients with IBS could aid in the development of successful treatment plans.

    Primary intestinal lymphomas are most common in the stomach. The mucosa associated lymphatic tissue (MALT)-lymphoma which is closely associated with helicobacter pylori is very well known. In most cases, these malignancies are from B-cells origin. Another possible point of manifestation, although not well known, is the small bowel. Both tumors have enormous capabilities to enlarge in the abdominal cave. This is responding to their often asymptomatic manifestation. The symptoms, if they occur, are widespread and unspecific. Ileus, diarrhae, abdominal pain or bleeding will be observed, in rare cases also perforation or gastrointestinal or cutaneous fistulas. Diagnostic imaging often demonstrates a tumour of massive size by then, which is echopoor in the abdominal ultrasound. Our report concerns two cases of small intestine lymphomas, which were diagnosed by CT-scanning and treated in our clinic in only a short period of time. The first case was a low malignant jejunal lymphoma which was almost asymptomatic, whereas the second case had an ileus, due to compression of the intestine because of a high malignant lymphoma of the ileocecal region.

    The authors report a case of a non-Hodgkin lymphoma of the small bowel, presenting with ulcerative lesions on radiological studies. primary intestinal lymphoma is considered a rare entity and its diagnosis criteria are quiet strict. The secondary form of the disease - involvement of the small bowel by systemic lymphoma - constitutes an infrequent clinical presentation of these neoplasms and must be considered when the criteria for primary disease are not fulfilled. Diagnosis is based on small bowel series studies and/or computed tomography findings, but the definitive diagnosis is established by biopsy. (author)

    Objective-To determine prevalence of histologic abnormalities in cats suspected, on the basis of compatible clinical signs and ultrasonographic findings, to have chronic small bowel disease; identify the most common underlying causes in affected cats; and compare methods for differentiating among the various causes of chronic small bowel disease. Design-Retrospective case series. Animals-300 client-owned domestic cats suspected to have chronic small bowel disease. Procedures-Medical records were reviewed to identify cats evaluated because of chronic vomiting, chronic small bowel diarrhea, or weight loss that also had ultrasonographic evidence of thickening of the small intestine. Cats were included in the study if full-thickness biopsy specimens had been obtained from ? 3 locations of the small intestine by means of laparotomy and biopsy specimens had been examined by means of histologic evaluation and, when necessary to obtain a diagnosis, immunohistochemical analysis and a PCR assay for antigen receptor rearrangement. Results-Chronic small bowel disease was diagnosed in 288 of the 300 (96%) cats. The most common diagnoses were chronic enteritis (n = 150) and intestinal lymphoma (124). Conclusions and Clinical Relevance-Results indicated that a high percentage of cats with clinical signs of chronic small bowel disease and ultrasonographic evidence of thickening of the small intestine had histologic abnormalities. Furthermore, full-thickness biopsy specimens were useful in differentiating between intestinal lymphoma and chronic enteritis, but such differentiation was not possible with ultrasonography or clinicopathologic testing alone.

    Full Text Available Abstract Background Due to the restrictive nature of a gluten-free diet, celiac patients are looking for alternative therapies. While drug-development programs include gluten challenges, knowledge regarding the duration of gluten challenge and gluten dosage is insufficient. We challenged adult celiac patients with gluten with a view to assessing the amount needed to cause some small-bowel mucosal deterioration. Methods Twenty-five celiac disease adults were challenged with low (1-3 g or moderate (3-5g doses of gluten daily for 12 weeks. Symptoms, small-bowel morphology, densities of CD3+ intraepithelial lymphocytes (IELs and celiac serology were determined. Results Both moderate and low amounts of gluten induced small-bowel morphological damage in 67% of celiac patients. Moderate gluten doses also triggered mucosal inflammation and more gastrointestinal symptoms leading to premature withdrawals in seven cases. In 22% of those who developed significant small- intestinal damage, symptoms remained absent. Celiac antibodies seroconverted in 43% of the patients. Conclusions Low amounts of gluten can also cause significant mucosal deterioration in the majority of the patients. As there are always some celiac disease patients who will not respond within these conditions, sample sizes must be sufficiently large to attain to statistical power in analysis.

  6. The scintigraphic determination of small intestinal transit time in patients with irritable bowel syndrome

    International Nuclear Information System (INIS)

    Diffuse disturbance in gastrointestinal motility may be present in patients with irritable bowel syndrome (IBS). To further investigate small intestinal motility in IBS patients small intestinal transit time (SITT) was determined and related to the symptom status. 11 female patients with IBS (mean age 29 years) were divided into those whose predominate symptom was diarrhea (N=6), and those with only constipation (N=5). All subjects ingested an isosmotic solution of lactulose (10 gm in 150cc of water) labeled with 99m-Tc-DTPA (Sn). The patient was studied supine under a 25 inch gamma camera with data collected at 1 frame per minute for 180 minutes or until activity appeared in the ascending colon. Regions of interest were selected over the cecum and ascending colon. The time of first appearance of radioactivity in the region of the cecum was taken as the small intestinal transit time. SITT in the 5 normal females was 98.7 +- 13 min (mean +- SEM). SITT in the IBS patients with diarrhea, 67.3 +- 7 min was significantly faster (p< 0.08). SITT in the constipated IBS patients, 126 +- 12 min, was slower than normals and significantly different from diarrhea patients (p< 0.001). These studies show that IBS patients with diarrhea have significantly faster SITT than normals while constipated IBS patients have significantly slower SITT than the diarrhea subgroup. Further, this study emphasizes the need to study the various symptomatic subgroups of IBs patients independently and indicates a possible role for abnormal SITT in the pathogenesis of IBS

  7. Assessment of Crohn's disease activity in the small bowel with MR and conventional enteroclysis: preliminary results

    International Nuclear Information System (INIS)

    Every single imaging finding that can be disclosed on conventional and MR enteroclysis was correlated with the Crohn's disease activity index (CDAI). Nineteen consecutive patients with Crohn's disease underwent colon endoscopy and both conventional and MR enteroclysis examinations. Seventeen MR imaging findings and seven conventional enteroclysis findings were ranked on a four-point grading scale and correlated with CDAI, with a value of 150 considered as the threshold for disease activity. Six patients had active disease in the colon according to colon endoscopy. In the remaining 13 patients, the presence of deep ulcers (P=0.002), small bowel wall thickening (P=0.022) and gadolinium enhancement of mesenteric lymph nodes (P=0.014) identified on MR enteroclysis images were strongly correlated to disease activity. The product of deep ulcers and enhancement of lymph node ranks identified on MR enteroclysis were the optimum combination for discriminating active from non-active disease (F-test: 55.95, P<0.001). Additionally, the ranking of deep ulcers on conventional enteroclysis provided statistically significant differences between active and non-active patients (F-test: 14.12, P=0.004). Abnormalities strongly suggestive of active Crohn's disease can be disclosed on MR enteroclysis examinations and may provide pictorial information for local inflammatory activity. (orig.)

    To prospectively evaluate magnetic resonance (MR) enterography for detecting mesenteric small-bowel tumours (MSBTs) and assess the added value of gadolinium-chelate injection. Over a 2-year period MR enterography examinations of 75 patients (33 men, 42 women; mean age, 53.8 years; range, 19-85) with suspected MSBT were blindly analysed by two readers for the presence of MSBT. Sensitivities, specificities, predictive positive values (PPVs), negative predictive values (NPVs) and accuracies of MR enterography for the detection of MSBT were calculated on per-patient and per-lesion bases. The McNemar test was used to compare sensitivities and specificities of the unenhanced and gadolinium-enhanced sets of MR enterographies. Thirty-seven MSBTs were pathologically confirmed in 26 patients. The mean tolerance score of the examinations was 0.7. On a per-patient basis, sensitivity, specificity, PPV, NPV and accuracy for detection of MSBT were 96 % [95 % CI, 89-100 %], 96 % [90-100 %], 93 % [83-100 %], 98 % [94-100 %] and 96 % [92-100 %], respectively. On a per-lesion basis, sensitivity and PPV were 70 % [56-85 %] and 93 % [83-100 %], respectively. Gadolinium injection yielded higher sensitivities on both bases (P = 0.008). MR enterography is an accurate and well-tolerated imaging modality for detecting MSBT. Intravenous administration of gadolinium-chelate improves sensitivity for MSBT detection. (orig.)

  9. Neuroendocrine tumors of the small bowels are on the rise: Early aspects and management

    Full Text Available Neuroendocrine tumors of the small bowel are on the rise. In the US they have increased by 300%-500% in the last 35 years. At the same time their prognosis is much improved. Today, most neuroendocrine tumors (NETs of the duodenum are detected “incidentally” and therefore recognized at an early stage. Duodenal NETs which are well differentiated, not larger than 10 mm and limited to the mucosa/submucosa can be endoscopically resected. The management of duodenal NETs ranging between 10 and 20 mm needs an interdisciplinary discussion. Endoscopic ultrasound is the method of choice to determine tumor size and depth of infiltration. Surgery is recommended for well-differentiated duodenal NET tumors greater than 20 mm, for localized sporadic gastrinomas (of any size and for localized poorly differentiated NE cancers. Surgery is recommended for any ileal NET. Advanced ileal NETs with a carcinoid syndrome are treated with long-acting somatostatin analogs. This treatment significantly improves (progression-free survival in patients with metastatic NETs of the ileum. For optimal NET management, tumor biology, type, localization and stage of the neoplasm, as well as the patient’s individual circumstances have to be taken into account.

    Full Text Available AIM: To estimate the prevalence of small intestinal bacterial overgrowth (SIBO in our geographical area (Western Sicily, Italy by means of an observational study, and to gather information on the use of locally active, non-absorbable antibiotics for treatment of SIBO.METHODS: Our survey included 115 patients fulfilling the Rome II criteria for diagnosis of irritable bowel syndrome (IBS; a total of 97 patients accepted to perform a breath test with lactulose (BTLact, and those who had a positive test, received Rifaximin (Normix®, Alfa Wassermann 1200 mg/d for 7 d; 3 wk after the end of treatment, the BTLact was repeated.RESULTS: Based on the BTLact results, SIBO was present in about 56% of IBS patients, and it was responsible for some IBS-related symptoms, such as abdominal bloating and discomfort, and diarrhoea. 1-wk treatment with Rifaximin turned the BTLact to negative in about 50% of patients and significantly reduced the symptoms, especially in those patients with an alternated constipation/diarrhoea-variant IBS.CONCLUSION: SIBO should be always suspected in patients with IBS, and a differential diagnosis is done by means of a “breath test”. Rifaximin may represent a valid approach to the treatment of SIBO.

    1989-10-01

    We report a patient with acrodermatitis enteropathica and a normal serum zinc level in whom the diagnosis was confirmed by plasma phospholipid fatty acid and a small bowel biopsy response to oral zinc therapy. Acrodermatitis enteropathica is a rare autosomal recessive condition of zinc deficiency characterised by chronic diarrhoea associated with failure to thrive, periorificial dermatitis and alopecia, susceptibility to infections and behavioural changes. Diagnosis is usually established by reduced serum zinc levels (classical acrodermatitis enteropathica). Paneth cell abnormalities on electron microscope of a small bowel biopsy can be supportive. A few cases with the typical picture of acrodermatitis enteropathica without hypozincaemia (variant acrodermatitis enteropathica) have been described. The diagnosis of variant acrodermatitis enteropathica to date has been based on an entirely empiric, but nonetheless convincing clinical response to oral zinc therapy. Laboratory aids to diagnosis have been lacking. PMID:2638577

    Full Text Available Background: Small bowel obstruction is the commonest surgical emergency encountered in childhood. We observed that intestinal obstruction caused by ascariasis is one of the leading causes of death in our children and consumes a major portion of our hospital resources. Other causes include intussusception, adhesions, volvulus, hernias, and worm obstruction. The aim of this study was to analyze the presentation, diagnosis, management of mechanical bowel and complication of obstruction in children. Patients and Methods : The study was conducted from Jan 2005 to Dec 2007 in the Department of Pediatric Surgery at Sheri- Kashmir Institute of Medical Sciences, Srinagar, Kashmir. All patients who presented in the emergency department with the diagnosis of intestinal obstruction were recruited. Patients with a dynamic obstruction were excluded from the study. Diagnosis was based on history and radiological findings. Data regarding the type of management, operative findings, operative procedure and post-operative complications were collected. Results: There were 207 patients admitted for intestinal obstruction. Males and females were equally affected. Most of the children (55% were aged 3-5 years. The causes of obstruction included ascariasis 131 (63.2%, adhesion 23 (11.1%, intussusception 21 (10.1%, obstructed hernia 17 (8.2%, and volvulus 11 (5.3%. One hundred twenty-six patients needed an operative intervention and 81 were treated conservatively. The operative procedures performed included enterotomy in 37 (29.3%, milking of worms in 18 (14.2%, resection anastomosis in 31 (24.6% and adhesiolysis in 13 (10.3%. Appendicular perforation was seen in 4 (1.9% and worm in gall bladder in 1 (0.5% patients. Surgical complications were wound infection in 18 (14.2%, burst abdomen in 5 (3.9% and fecal fistula in 3 (2.3% patients. Conclusion: Intestinal obstruction is associated with considerable morbidity and mortality in children. Obstruction by ascariasis constituted the majority of intestinal obstruction in this study. Efforts should be made to eradicate ascariasis in endemic areas through proper sanitation, hygiene and use of antihelminthics.

    Full Text Available Abstract Background Familial adenomatous polyposis (FAP is a hereditary disorder characterized by polyposis along the gastrointestinal tract. Information on adenoma status below the duodenum has previously been restricted due to its inaccessibility in vivo. Capsule Endoscopy (CE may provide a useful adjunct in screening for polyposis in the small bowel in FAP patients. This study aims to evaluate the effectiveness of CE in the assessment of patients with FAP, compared to other imaging modalities for the detection of small bowel polyps. Method 20 consecutive patients with previously diagnosed FAP and duodenal polyps, presenting for routine surveillance of polyps at The Royal Melbourne Hospital were recruited. Each fasted patient initially underwent a magnetic resonance image (MRI of the abdomen, and a barium small bowel follow-through study. Capsule Endoscopy was performed four weeks later on the fasted patient. An upper gastrointestinal side-viewing endoscopy was done one (1 to two (2 weeks after this. Endoscopists and investigators were blinded to results of other investigations and patient history. Results Within the stomach, upper gastrointestinal endoscopy found more polyps than other forms of imaging. SBFT and MRI generally performed poorly, identifying fewer polyps than both upper gastrointestinal and capsule endoscopy. CE was the only form of imaging that identified polyps in all segments of the small bowel as well as the only form of imaging able to provide multiple findings outside the stomach/duodenum. Conclusion CE provides important information on possible polyp development distal to the duodenum, which may lead to surgical intervention. The place of CE as an adjunct in surveillance of FAP for a specific subset needs consideration and confirmation in replication studies.

  14. Preoperative Helical Tomotherapy and Megavoltage Computed Tomography for Rectal Cancer: Impact on the Irradiated Volume of Small Bowel

    International Nuclear Information System (INIS)

    Purpose: Preoperative (chemo)radiotherapy is considered to be standard of care in locally advanced rectal cancer, but is associated with significant small-bowel toxicity. The aim of this study was to explore to what extent helical tomotherapy and daily megavolt (MV) CT imaging may reduce the irradiated volume of small bowel. Methods and Materials: A 3D-conformal radiotherapy (3D-CRT) plan with CTV-PTV margins adjusted for laser-skin marks (15, 15, and 10 mm for X, Y, and Z directions, respectively) was compared with helical tomotherapy (IMRT) using the same CTV-PTV margins, and to helical tomotherapy with margins adapted to daily MV-CT imaging (IMRT/IGRT; 8, 11, 7, and 10 mm for X, Yant, Ypost and Z resp.) for 11 consecutive patients. The planning goals were to prescribe 43.7 Gy to 95% of the PTV, while minimizing the volume of small bowel receiving more than 15 Gy (V15SB). Results: The mean PTV was reduced from 1857.4 ± 256.6 cc to 1462.0 ± 222.3 cc, when the CTV-PTV margins were adapted from laser-skin marks to daily MV-CT imaging (p 15SB decreased from 160.7 ± 102.9 cc to 110.9 ± 74.0 cc with IMRT and to 81.4 ± 53.9 cc with IMRT/IGRT (p < 0.01). The normal tissue complication probability (NTCP) for developing Grade 2+ diarrhea was reduced from 39.5% to 26.5% with IMRT and to 18.0% with IMRT/IGRT (p < 0.01). Conclusion: The combination of helical tomotherapy and daily MV-CT imaging significantly decreases the irradiated volume of small bowel and its NTCP.

  19. Determining the efficiency of a commercial belly board device in reducing small bowel volume in rectal cancer patients

    International Nuclear Information System (INIS)

    The purpose of this treatment planning study was to evaluate the efficiency of a commercial belly board device in reducing the irradiated volume of the small bowel. In this study 10 patients with rectal carcinoma receiving postoperative radiotherapy were included. For each of them we made two computer tomography series in prone position. In the first one the patients were lying on the flat table top, and in the second one they were lying on the belly board device which is under investigation. On both series we calculated and optimized plans according to the standing protocol of our department. From the dose-volume histograms of these plans we compared the volumes of the small bowel irradiated to three dose levels 15, 30 and 45 Gy. The results showed that the absolute irradiated volumes were significantly smaller in the plans with the belly board device. Based on these results we believe that the employment of this belly board device will reduce the acute and late small bowel toxicity. This should be verified with a clinical study.(Author)

  20. The role of computed tomography in the diagnosis and management of clinically occult post-traumatic small bowel perforation

    International Nuclear Information System (INIS)

    Purpose: To evaluate the use of computed tomography [CT] in the diagnosis of occult post-traumatic small bowel perforation and to discuss the role of CT in the management of this patient group. Method: This review includes three patients who presented with mild abdominal symptoms following minor blunt abdominal trauma. Initial radiographs and laboratory investigations were unremarkable but their symptoms failed to resolve and contrast-enhanced CT was performed for further evaluation. Results: In each case the CT appearances were indicative of localised small bowel perforation, with no evidence of other visceral injury. In two patients pockets of free intraperitoneal air were present closely related to the second part of the duodenum suggesting injury at this site. In the third case, a thickened proximal jejunal loop was demonstrated with free air and fluid in the adjacent mesentery consistent with a focal perforation. These CT findings were subsequently confirmed at laparotomy. Conclusion: CT is an accurate diagnostic tool in the assessment of clinically and radiologically occult traumatic small bowel injury. The use of CT should be considered in patients who have unresolving abdominal symptoms even after apparently insignificant abdominal trauma.

  1. Percutaneous endoscopic gastrojejunostomy for a patient with an intractable small bowel injury after repeat surgeries: a case report

    Full Text Available Abstract Introduction The management of intestinal injury can be challenging, because of the intractable nature of the condition. Surgical treatment for patients with severe adhesions sometimes results in further intestinal injury. We report a conservative management strategy using percutaneous endoscopic gastrojejunostomy for an intractable small bowel surgical injury after repeated surgeries. Case presentation A 78-year-old Japanese woman had undergone several abdominal surgeries including urinary cystectomy for bladder cancer. After this operation, she developed peritonitis as a result of a small bowel perforation thought to be due to an injury sustained during the operation, with signs consistent with systemic inflammatory response syndrome: body temperature 38.5°C, heart rate 92 beats/minute, respiratory rate 23 breaths/minute, white blood cell count 11.7 × 109/L (normal range 4-11 × 109/?L. Two further surgical interventions failed to control the leak, and our patient's clinical condition and nutritional status continued to deteriorate. We then performed percutaneous endoscopic gastrojejunostomy, and continuous suction was applied as an alternative to a third surgical intervention. With this endoscopic intervention, the intestinal leak gradually closed and oral feeding became possible. Conclusion We suggest that the technique of percutaneous endoscopic gastrojejunostomy combined with a somatostatin analog is a feasible alternative to surgical treatment for small bowel leakage, and is less invasive than a nasojejunal tube.

  2. Polyethylene glycol solution as an oral contrast agent for MRI of the small bowel in a patient population

    International Nuclear Information System (INIS)

    Aim: To assess the efficacy of polyethylene glycol solution as an oral contrast agent in a patient population. Material and methods: Patients were fasted from 12.00 am. Administration of the oral contrast medium commenced 15 min before imaging and comprised one sachet of Norgine (Klean-prep, Middlesex, UK) reconstituted in 1 l water of which the patient took between 500-750 ml. Norgine is a balanced mixture of polyethylene glycol and electrolytes, which when added to water produces a clear colourless, iso-osmotic solution. Results: In total 38 candidates were identified retrospectively covering a 2-year period. Visualization of the jejunum, ileal loops and ileocaecal region was excellent or sufficient in 87, 95 and 89%, respectively. The time taken to obtain complete visualization of the small bowel, from the jejunum to the ileocecal region varied from 15-240 min with an average time of 65 min and 73.7% of patients necessitating delayed imaging. Conclusions: Polyethylene glycol was demonstrated to be an excellent oral contrast medium in distending the small bowel. However, small bowel transit times were significantly delayed and problematic necessitating repeated imaging within the patient population. As result of theses findings longer examination time should be expected within a patient population and this should be borne in mind when scheduling patients

  4. Acute small bowel toxicity and preoperative chemoradiotherapy for rectal cancer: Investigating dose-volume relationships and role for inverse planning

    International Nuclear Information System (INIS)

    Purpose: The relationship between volume of irradiated small bowel (VSB) and acute toxicity in rectal cancer radiotherapy is poorly quantified, particularly in patients receiving concurrent preoperative chemoradiotherapy. Using treatment planning data, we studied a series of such patients. Methods and Materials: Details of 41 patients with locally advanced rectal cancer were reviewed. All received 45 Gy in 25 fractions over 5 weeks, 3-4 fields three-dimensional conformal radiotherapy with daily 5-fluorouracil and folinic acid during Weeks 1 and 5. Toxicity was assessed prospectively in a weekly clinic. Using computed tomography planning software, the VSB was determined at 5 Gy dose intervals (V5, V1, etc.). Eight patients with maximal VSB had dosimetry and radiobiological modeling outcomes compared between inverse and conformal three-dimensional planning. Results: VSB correlated strongly with diarrheal severity at every dose level (p 5 and V15. Conclusions: A strong dose-volume relationship exists between VSB and acute diarrhea at all dose levels during preoperative chemoradiotherapy. Our constructed model may be useful in predicting toxicity, and this has been derived without the confounding influence of surgical excision on bowel function. Inverse planning can reduce calculated dose to small bowel and late NTCP, and its clinical role warrants further investigation

    Full Text Available Coexistence of a diverticular abscess and colorectal cancer is an extremely rare phenomenon. The clinical presentation and the extension of a diverticular abscess could cause mis-staging of colon cancer. We are presenting an overstaged colon cancer due to a diverticular abscess penetrating into the abdominal wall. A 65-year-old male patient with a history of an enlarging mass in the left lower quadrant of the abdomen was admitted to our service. Diagnostic studies revealed a sigmoid tumor communicating with an abdominal wall mass. The patient was clinically staged as T4 N1. Exploration revealed a diverticular abscess penetrating into the abdominal wall and a sigmoid tumor. Histopathological examination reported an intermediately differentiated T3 N0 adenocarcinoma of the sigmoid colon. After an uneventful postoperative recovery, the patient was referred to chemotherapy. [Arch Clin Exp Surg 2015; 4(4.000: 231-233

    Full Text Available Abstract Introduction Bariatric surgery is on the increase throughout the world. Jejunoileal bypass bariatric procedures have fallen out of favor in western surgical centers due to the high rate of associated complications. They are, however, performed routinely in other centers and as a consequence of health tourism, management of complications related to these procedures may still be encountered. Case presentation We describe a rare case of small bowel obstruction in a 45-year-old British Caucasian woman, secondary to a volvulus of the jejunoileal anastomosis following bariatric bypass surgery. The pre-operative diagnosis was confirmed by radiology. We describe a successful surgical technique for this rare complication. Conclusions Bariatric surgery may be complicated by bowel obstruction. Early imaging is vital for diagnosis and effective management. The use of our surgical technique provides a simple and effective approach for the successful management of this bariatric complication.

    Full Text Available Abstract Background Leucocyte recruitment and inflammation are key features of high dose radiation-induced tissue injury. The inflammatory response in the gut may be more pronounced following radiotherapy due to its high bacterial load in comparison to the response in other organs. We designed a model to enable us to study the effects of radiation on leucocyte-endothelium interactions and on intestinal microflora in the murine ileum. This model enables us to study specifically the local effects of radiation therapy. Method A midline laparotomy was performed in male C57/Bl6 mice and a five-centimetre segment of ileum is irradiated using the chamber. Leucocyte responses (rolling and adhesion were then analysed in ileal venules 2 – 48 hours after high dose irradiation, made possible by an inverted approach using intravital fluorescence microscopy. Furthermore, intestinal microflora, myeloperoxidase (MPO and cell histology were analysed. Results The highest and most reproducible increase in leucocyte rolling was exhibited 2 hours after high dose irradiation whereas leucocyte adhesion was greatest after 16 hours. Radiation reduced the intestinal microflora count compared to sham animals with a significant decrease in the aerobic count after 2 hours of radiation. Further, the total aerobic counts, Enterobacteriaceae and Lactobacillus decreased significantly after 16 hours. In the radiation groups, the bacterial count showed a progressive increase from 2 to 24 hours after radiation. Conclusion This study presents a refinement of a previous method of examining mechanisms of radiation enteropathy, and a new approach at investigating radiation induced leucocyte responses in the ileal microcirculation. Radiation induced maximum leucocyte rolling at 2 hours and adhesion peaked at 16 hours. It also reduces the microflora count, which then starts to increase steadily afterwards. This model may be instrumental in developing strategies against pathological recruitment of leucocytes and changes in intestinal microflora in the small bowel after radiotherapy.

    Full Text Available Fecaloma is a mass of hardened feces being impacted mostly in rectum and sigmoid. The most common sites of the fecaloma is the sigmoid colon and the rectum. There are several causes of fecaloma and have been described in association with Hirschsprung’s disease, psychiatric patients, Chagas disease, both inflammatory and neoplastic, and in patients suffering with chronic constipation. Up to now several cases of giant fecaloma has been reported in the literature most of them presenting with megacolon or urinary retention. We herein report a case of giant fecaloma leading to bowel obstruction who was successfully treated by surgery. A 30-yrar-old man presented with sign and symptoms of acute bowel obstruction. He underwent exploratory laparotomy and enterotomy. He was found to have a giant fecaloma causing bowel obstruction in the jejunum. He was discharged after the operation with good condition. Jejunal fecaloma is extremely rare condition.

    Full Text Available OBJETIVO: Investigar a evolução clínica do transplante de intestino delgado ortotópico em ratos não-isogênicos. MÉTODOS: Setenta e dois ratos Wistar não-isogênicos, com peso variando entre 250 e 300g, foram utilizados como doadores e receptores em 36 transplantes ortotópicos de intestino delgado sem [...] regime de imunossupressão. Os enxertos foram implantados nos receptores por meio de anastomose microvascular término-lateral aorta-aorta e porto-cava. A duração do procedimento, evolução clínica dos animais e sobrevida foram avaliados. Sobrevida menor que quatro dias foi considerada falha técnica. Os receptores foram sacrificados quando apresentaram sinais de rejeição grave do enxerto ou sobrevida maior que 120 dias. Necropsias foram realizadas em todos os receptores para avaliar alterações histopatológicas no enxerto. RESULTADOS: O tempo médio para o procedimento foi de 107 minutos. Seis receptores (16,7%) apresentaram falha técnica Vinte e sete receptores (75%) foram sacrificados por rejeição sendo dezenove (52,7%) entre o 7º e 15º dia de pós-operatório e oito (22,2%) entre o 34º e 47º. Análise histopatológica confirmou rejeição celular aguda severa nesses recipientes. Evolução sem complicações e sobrevida maior que 120 dias sem sinais de rejeição foi observada em três receptores (8,3%). CONCLUSÃO: O transplante de intestino delgado ortotópico em ratos Wistar não-isogênicos sem regime de imunossupressão apresenta evolução clínica variada. Abstract in english PURPOSE: To investigate the clinical evolution of orthotopic small bowel transplantation in outbred rats. METHODS: Seventy-two outbred Wistar rats weighting from 250 to 300g were used as donor and recipient in 36 consecutives ortothopic small intestine transplantation without immunosuppression. The [...] graft was transplanted into the recipient using end-to-side aortic and portacaval microvascular anastomosis. Procedure duration, animal clinical course and survival were evaluated. Survival shorter than four days was considered technical failure. Recipients were sacrificed with signs of severe graft rejection or survival longer than 120 days. Necropsies were performed in all recipients to access histopathological changes in the graft. RESULTS: Median time for the procedure was 107 minutes. Six recipients (16.7%) presented technical failure. Twenty-seven recipients were sacrificed due to rejection, being nineteen (52.7%) between 7th and 15th postoperative day and eight (22.2%) between 34th and 47th postoperative day. Graft histology confirmed severe acute cellular rejection in those recipients. Uneventful evolution and survival longer than 120 days without rejection were observed in three recipients (8.3%). CONCLUSION: Intestinal transplantation in outbred rats without immunosuppressant regiment accomplishes variable clinical evolution.

    Full Text Available [...] Abstract in english The laparoscopic approach is an alternative for the elective treatment of diverticular colon disease (DCD). Aim: To analyze the results of patients electively operated for DCD using a laparoscopic technique. Material and Methods: Data of patients with DCD operated using laparoscopy at the Catholic U [...] niversity of Chile Clinical Hospital were prospectively recorded from January 1999 to August 2006. Indications for surgery were repetitive crises of acute diverticulitis, the persistence of the symptoms or anatomic deformity after the first crisis and complicated diverticulitis (Hinchey 1-2) that responded to the medical treatment. The laparoscopic technique used five ports and the surgical specimen was extracted through a suprapubic approach. Results: One hundred and six patients aged 32 to 82 years (49% females) were operated in the study period. Fifty five percent had a previous abdominal surgery. The mean operative time was 213 minutes (range: 135-360). Four patients were converted to open surgery (3.7%). One or more early post-operative complications were observed in five patients (4.7%). The mean time for passing gases and reinitiate liquid diet was 1.7 and 2.4 days respectively. The median post operative stay after surgery was 4 days. There was no operative mortality. Mean follow-up time was 27 months and only one patient (0.9%) had a new episode of acute diverticular disease, with a satisfactory response to medical treatment. No patient has developed bowel obstruction. Conclusions: The laparoscopic approach is a safe alternative in the elective surgical treatment of DCD

  13. Short bowel syndrome

    International Nuclear Information System (INIS)

    This thesis describes some aspects of short bowel syndrome. When approximately 1 m or less small bowel is retained after extensive resection, a condition called short bowel syndrome is present. Since the advent of parenteral nutrition, the prognosis of patients with a very short bowel has dramatically improved. Patients with 40 to 100 cm remaining jejunum and/or ileum can generally be maintained with oral nutrition due to increased absorption of the small bowel remnant as result of intestinal adaptation. This study reports clinical, biochemical and nutritional aspects of short bowel patients on oral or parenteral nutrition, emphasizing data on absorption of various nutrients and on bone metabolism. Furthermore, some technical apsects concerning long-term parenteral nutrition are discussed. (Auth.)

    Background/Aims Capsule endoscopy (CE) is widely used. However, CE has limitations including incomplete examination, inadequate bowel preparation, and retention. The aim of this study was to estimate the indications for and detection, completion, and retention rates of small intestine CE based on the 10-year data from the Korean Capsule Endoscopy Registry. Methods Twenty-four hospitals participated in this study. Clinical information, such as reasons for CE, method and quality of bowel preparation, and incomplete examination and capsule retention rates, was collected and analyzed. Results A total of 2,914 CEs were registered. The most common reason for CE was obscure gastrointestinal bleeding (59%). Significant lesions were detected in 66% of cases. Positive CE diagnosis occurred in 63% of cases. The preparation method did not significantly affect the quality of bowel preparation for CE. The overall incomplete rate was 33%, and was high in the elderly and those with poor bowel preparation. Capsule retention was 3% and high in patients with small bowel tumors and Crohn's disease and in children under 10 years of age. Conclusions CE is a valuable technique; while the overall detection rate is high, incompletion and retention rates are also relatively high. CE should be carefully considered in the elderly and children less than 10 years of age, as well as in patients with small bowel tumors and Crohn's disease. PMID:26473123

    Small-bowel MRI based on contrast-enhanced T1-weighted sequences has been challenged by diffusion-weighted imaging (DWI) for detection of inflammatory bowel lesions and complications in patients with Crohn disease. To evaluate free-breathing DWI, as compared to contrast-enhanced MRI, in children, adolescents and young adults with Crohn disease. This retrospective study included 33 children and young adults with Crohn disease ages 17 {+-} 3 years (mean {+-} standard deviation) and 27 matched controls who underwent small-bowel MRI with contrast-enhanced T1-weighted sequences and DWI at 1.5 T. The detectability of Crohn manifestations was determined. Concurrent colonoscopy as reference was available in two-thirds of the children with Crohn disease. DWI and contrast-enhanced MRI correctly identified 32 and 31 patients, respectively. All 22 small-bowel lesions and all Crohn complications were detected. False-positive findings (two on DWI, one on contrast-enhanced MRI), compared to colonoscopy, were a result of large-bowel lumen collapse. Inflammatory wall thickening was comparable on DWI and contrast-enhanced MRI. DWI was superior to contrast-enhanced MRI for detection of lesions in 27% of the assessed bowel segments and equal to contrast-enhanced MRI in 71% of segments. DWI facilitates fast, accurate and comprehensive workup in Crohn disease without the need for intravenous administration of contrast medium. Contrast-enhanced MRI is superior in terms of spatial resolution and multiplanar acquisition. (orig.)

    Diverticulum is considered as a common lesion involving any gastrointestinal tract from the pharynx to the rectum. We reviewed 5,806 cases of upper G-I series and 801 cases of double contrast barium enema during the period from Jan.1978 to Dec. 1981 in the Department of Radiology, School of Medicine, Jeonbug National University Hospital to analyze diverticula of the entire gastrointestinal tract. The results were as follows: 1. Roentgen examination of 5,806 esophagus, stomachs, duodenums and small bowels, and 801 colons during the past four years: diverticula of the esophagus, 60 cases (1.0%); diverticula of the stomach, 42 cases (0.7%); diverticula of the duodenum, 358 cases (6.2%); diverticula of the small bowel, 20 cases (0.3%); diverticula of the colon, 26 cases (3.2%). The location of diverticula in order of frequency was duodenum, colon, esophagus, stomach and small bowel. 2. The most common site of diverticula of each gastrointestinal tract was as follows: diverticula of the esophagus, middle portion (84.7%); diverticula of the stomach, the cardia (59.5%); diverticula of the duodenum, the second portion (81.3%); diverticula of the small bowel, the jejunum (96.4%)-especially the larger percentage were observed at the upper jejunum near the ligament of Treitz; diverticula of the colon, the right sided colon (80.8%)-the cecum and ascending colon (57.1%). 3. Diverticula may occur at any age. The majority of diverticula of the entire gastrointestinal tract were observed over 40 years of age. Especially in diverticula of the duodenum and colon, their frequency increase with age. 4. Duodenal diverticula were observed more frequently in woman than in man but in diverticula of the esophagus, stomach, small bowel and colon, male was more frequently affected. 5. The size of diverticula of the entire gastrointestinal tract was variable. The majority of diverticula of the esophagus, stomach, duodenum and small bowel were intermediate in size (10-49 mm). Diverticula of the colon were usually smaller than 10 mm. 6. Multiplicity of diverticula of the entire gastrointestinal tract was 16.2% of 506 cases. In diverticula of the esophagus, stomach, duodenum and small bowel, single lesion was more frequently found. On the other hand, the majority of diverticula of the colon were found as multiple lesion(69.2%)

    Full Text Available We report a rare case of a small-bowel lymphangioma causing massive gastrointestinal (GI bleeding that we successfully diagnosed and treated using double-balloon enteroscopy (DBE. An 81-year-old woman suffering from repeated GI bleeding of unknown origin underwent a capsule endoscopy at a previous hospital. She was suspected of having bleeding from the jejunum, and was referred to our department for diagnosis and treatment. An oral DBE revealed a 20 mm × 10 mm, regularly surfaced, white to yellowish, elongated, pedunculated jejunal polyp with small erosions at 10 cm distal to the ligament of Treiz. Since no other source of bleeding was identified by endoscopy in the deep jejunum, an endoscopic polypectomy (EP was performed for this lesion. A subsequent histopathological examination of the resected polyp showed clusters of lymphatic vessels with marked cystic dilatation in the submucosa and the deep layer of the lamina propria mucosae. These characteristics are consistent with the typical features of small-bowel lymphangioma with erosions. Although clipping hemostasis was performed during EP, re-bleeding occurred. Finally, a complete hemostasis was achieved by performing an additional argon plasma coagulation.

  3. Crohn's disease at the small bowel imaging by the ultrasound-enteroclysis

    International Nuclear Information System (INIS)

    Summary: Crohn's disease is more likely a systemic disease governed by a shift in the immune response, thus affecting the whole MALT system. Its treatment should be as conservative as possible and surgery is usually taking place after complications like indolent fistulations, stenoses, bleeding, or bowel perforation started. Standard radiological methods to check the extent of the disease are loaded either with certain radiation exposure (enteroclysis, CT) or lack standardization (ultrasound). The aim of this small study was to evaluate the worth of ultrasound-enteroclysis in detecting the extent and complications of the Crohn's disease in surgically treated patients. Material and methods: Since 1997, when we started with the ultrasound-enteroclysis, 246 surgical performances were involved into our study. Out of them, 181 had conventional abdominal intestinal ultrasound as well as conventional enteroclysis within 1 week. Remaining 65 cases were diagnosed by the ultrasound-enteroclysis. Intestinal ultrasound was performed on the Ultramark 3000 HDI device with autofocussable convex 5 MHz and linear 7.5 MHz probes or nowadays ATL 5000 HDI, 7-12 MHz linear probe. No contrast enhancement was used. Enteroclysis was done with the Micropaque suspension diluted 1:1 with HP-7000 300 ml with its application rate up to 75 ml/min followed by HP-7000 solution 2000 ml, application rate of 120 ml/min. The patients with ultrasound-enteroclysis were applied HP 7000 solution only (2000 ml, rate 100 ml/s) via an enteroclysis catheter. All investigations were video-recorded. Results: Consent with the per-operative finding was reached in 162 from 181 enteroclyses and in 169 of 181 ultrasounds. Ultrasound-enteroclysis was precise in 61 cases from 65. Among these, 60 patients had the recurrence during the treatment proved by clinical and laboratory results. This re-activation was clearly revealed in 38 from 43 cases by enteroclysis, 41 from 43 by US and in 16 from 17 by ultrasound-enteroclysis. From 30 patients that developed acute complication non-responding to the conservative therapy (abscesses, fistulas and intestinal obstructions) there were 18 from 20 accurately diagnosed by enteroclysis, only 12 from 20 by US and 9 from 10 by US-enteroclysis. The differences were either statistically non-significant or there were too small numbers to give sensible statistical results, but low sensitivity of ultrasound in complications (p = 0.05). Conclusion: US-enteroclysis seems to became the standard examination of patients with Crohn's disease mainly in those with unclear conventional ultrasound. The most important fact is that this examination significantly decreases the radiation load when maintaining high sensitivity. This is very important namely in patients with Crohn's disease that require life-long observation and repeated examinations. This examination is much more easy to standardize than the conventional US

  4. 14C-lactose breath tests during pelvic radiotherapy: the effect of the amount of small bowel irradiated

    International Nuclear Information System (INIS)

    Thirty patients who were undergoing pelvic radiotherapy had 14C-lactose breath tests performed in the first and fifth weeks of treatment. In Group I (21 patients), a significant portion of the small intestine was irradiated, and in Group II (9 patients), only a small portion of the small intestine was irradiated. In Group I, the average reductions in the excretion of ingested 14C between the first- and fifth-week tests were 41.5% at 1/2 hour postingestion (p0.05). The data suggest that lactose malabsorption is a factor in the etiology of the nausea, vomiting, and diarrhea experienced by patients who are undergoing pelvic radiotherapy, and that the amount of bowel included in the treatment volume significantly influences the degree of malabsorption

    To evaluate the change of the wall of obstructed small bowel loop on ultrasonography (US), the changes of pre- and post-obstructed segments were examined by using US and correlated with histopathologic findings. Small bowel loops of seven rabbits were caused to be obstructed by surgery. One of them was sacrificed after 12 hours, and six were after 24 hours. The bowel loop of about 10 cm in length was cut and removed from obstructed site for evaluation with US and correlation with histopathologic findings. One control was also included and correlated by the same way, without bowel obstruction. After US examination, the bowel loops were opened at the mesenteric border. They were mounted into hard paper, and put in a plastic pail filled with 2 liters of physiologic saline. The specimens were imaged with 10 MHz linear array transducer with high definition zoom. After sonographic examination, the specimens were fixed with 10% formalin solution and stained by hematoxylin-eosin. The segments of small bowel showed three layers on US, which were hyperechoic, hypoechoic, and hyperechoic from the mucosal surface. The total thickness of the pre-obstructed segments was 1.65 {+-} 0.15 mm, and of post-obstructed was 1.62 {+-} 0.14 mm; there was no significant difference (p>0.05). The ratio of the second hypoechoic layer to total thickness was 23% at pre-obstructed segments, 17% at post-obstructed, and 7% at the control. Under microscopic examination, the total thickness of the pre-obstructed segments were measured as 0.95 {+-} 0.12 mm, and that of the post-obstructed was measured as 0.9{+-} 0.11 mm; there was no significant difference (p>0.05). The total thickness on US was about 0.7 mm thicker than in microscopic findings, so considering the ratio of each layers, the first hyperechoic and the second hypoechoic layers were assumed to be mucosal layer, and the third hyperechoic layer was assumed to be submucosal and muscle layers. Histopathologic findings of both pre- and post-obstructed segments revealed increased goblet cells, lymphatic dilatation of villi at the mucosal layer, fibrosis, edema, hemorrhage, and infiltration of inflammatory cells at the submucosal layer. Only in pre-obstructed segments, the muscle layer showed muscle cell hypertrophy, a decreasing of interspace between inner circular and outer longitudinal muscle layers and also among intermuscular fibers. Hemorrhage, edema,and inflammatory cells infiltration were also observed in the muscle layer. There was no increased wall thickness of the pre-observed segments, and the proportion of the second hyperechoic layer was increased. The histopathologic findings of it corresponded to the lymphatic dilatation of the mucosal layer.

  6. Chromium-51-EDTA and technetium-99m-DTPA excretion for assessment of small bowel Crohn's disease

    International Nuclear Information System (INIS)

    In the present study, 4 patients with radiologically documented Crohn's disease were given 100 ?Ci of Cr-51-EDTA and 5 mCi of Tc-99m-DTPA together orally in 10ml of water, and urine was collected during the following 24 hr period. Sequential imaging of the stomach and the GI tract was done with a LFOV gamma camera at 10 min intervals until the activity cleared the small bowel. The images failed to show any localization of the activity in any disease process and no extraintestinal accumulation site was observed scintigraphically. Mean 24 hr urinary excretion for Tc-99m-DTPA was 4.8 +- 2.6% comparable to that of Cr-51-EDTA in these patients. This study suggests that a comparable oral dose of Tc-99m-DTPA could be substituted for Cr-51-EDTA as a far more readily available agent for documenting small bowel Crohn's disease by quantitative assessment of its urinary excretion

    The effects of pectin and cellulose on fat absorption after massive small-bowel resection were studied in rats. Weanling Wistar rats underwent 80% resection of the small intestine with gastrostomy, and fat emulsion labeled with 14C-linoleate was given via a gastrostomy tube for the fat absorption test on the 10th postoperative day. They were classified into three groups by diet as follows: E group, a fiber-free, chemically defined diet (CDD); EP group, CDD with 2% pectin; and EC group, CDD with 2% cellulose. The cumulative and hourly output of 14C in the expired air, the absorption rate of 14C in the intestine, and the metabolic utilization rate of 14C were calculated. The cumulative 14CO2 output was significantly lower in the EC group than in the E and EP groups. However, there was no significant difference in the 14CO2 output between the E and EP groups. The highest hourly 14CO2 output in the E and EP groups was observed during the first 2 hours. However, in the EC group, this fluctuated at low levels. No significant difference in the 1-14C-linoleate absorption rate was observed between the E and EP groups, whereas it was significantly lower in the EC group than in the E and EP groups. The metabolic utilization rate of 1-14C-linoleate showed no significant difference among the three groups. These data suggest that an addition of pectin to CDD does not impair small intestinal absorption of 1-14C-linoleate after massive small-bowel resection, and an addition of cellulose decreases absorption of 1-14C-linoleate.

    The small bowel is a hollow organ involved in the transit and absorption of food. In relation to its anatomical location, a significant amount of this organ is exposed in whole or in part to ionizing radiation in external radiotherapy during abdominal or pelvic irradiation either for primary cancers or metastasis. The acute functional changes during external beam radiation are mainly leading to diarrhea, abdominal pain and bloating. The main late side effects of irradiation of the small intestine are chronic diarrhea, malabsorption with steatorrhoea, abdominal spasms, intestinal obstruction, bleeding and fistulas. The architecture of the small intestine may be considered as parallel with a significant correlation between the irradiated volume of small bowel and the likelihood of acute toxicity, whatever the dose. The literature analysis recommends to consider the volume of small bowel receiving 15 Gy (threshold of 100 to 200 cm{sup 3}) but also 30 and 50 Gy (thresholds of 35 to 300 cm{sup 3}, depending on the level of dose considered). Modern techniques of conformal radiotherapy with modulated intensity will probably have beneficial impact on small bowel toxicity. (authors)

  12. Biodistribution of the radiopharmaceutical sodium pertechnetate (Na99mTcO4) after massive small bowel resection in rats

    International Nuclear Information System (INIS)

    Purpose: To evaluate the biodistribution of sodium pertechnetate (Na99mTcO4) in organs and tissues, the morphometry of remnant intestinal mucosa and ponderal evolution in rats subjected to massive resection of the small intestine. Methods:Twenty-one Wistar rats were randomly divided into three groups of 7 animals each. The short bowel (SB) group was subjected to massive resection of the small intestine; the control group (C) rats were not operated on, and soft intestinal handling was performed in sham rats. The animals were weighed weekly. On the 30th postoperative day, 0.1 mL of Na99mTcO4, with mean activity of 0.66 MBq was injected intravenously into the orbital plexus. After 30 minutes, the rats were killed with an overdose of anesthetic, and fragments of the liver, spleen, pancreas, stomach, duodenum, small intestine, thyroid, lung, heart, kidney, bladder, muscle, femur and brain were harvested. The biopsies were washed with 0.9% NaCl.,The radioactivity was counted using Gamma Counter WizardTM 1470, Perkin-Elmer. The percentage of radioactivity per gram of tissue (%ATI/g) was calculated. Biopsies of the remaining jejunum were analysed by HE staining to obtain mucosal thickness. Analysis of variance (ANOVA) and the Tukey test for multiple comparisons were used, considering p99mTcO4 in the organs of the groups studied (p>0.05). An increase in the weight of the SB rats was observed after the second postoperative week. The jejunal mucosal thickness of the SB rats was significantly greater than that of C and sham rats (p99mTcO4 was not affected by massive intestinal resection, suggesting that short bowel syndrome is not the cause of misleading interpretation, if an examination using this radiopharmaceutical is indicated.

    The aim was to compare bowel distension and diagnostic properties of magnetic resonance imaging of the small bowel with oral contrast (MRI per OS) with magnetic resonance enteroclysis (MRE). Forty patients with suspected Crohn's disease (CD) were examined with both MRI methods. MRI per OS was performed with a 6% mannitol solution and MRE with nasojejunal intubation and a polyethylenglycol solution. MRI protocol consisted of balanced fast field echo (B-FFE), T2 and T1 sequences with and without gadolinium. Two experienced radiologists individually evaluated bowel distension and pathological findings including wall thickness (BWT), contrast enhancement (BWE), ulcer (BWU), stenosis (BWS) and edema (EDM). The diameter of the small bowel was smaller with MRI per OS than with MRE (difference jejunum: 0.55 cm, p < 0.001; ileum: 0.35 cm, p < 0.001, terminal ileum: 0.09 cm, p = 0.08). However, CD was diagnosed with high diagnostic accuracy (sensitivity, specificity, positive and negative predictive values: MRI per OS 88%, 89%, 89%, 89%; MRE 88%, 84%, 82%, 89%) and inter-observer agreement (MRI per OS k = 0.95; MRE k = 1). In conclusion, bowel distension was inferior in MRI per OS compared to MRE. However, both methods diagnosed CD with a high diagnostic accuracy and reproducibility. (orig.)

These benefits are lost if the surgery is converted to an open procedure. We searched for predictive factors of conversión in patients with diverticular disease. A study of 79 patients who underwent laparoscopic sigmoid resection was performed, comparing those who underwent conversión and those who didn't. Material and Methods: A retrospective cohort study was done in a third level hospital of the patients who required laparoscopic sigmoidectomy during the last 7 years. Analysis: The t Student, test and the exact Fisher test were used. We considered p < 0.05 (95% confidence interval as statistically significant. Results: The pre operative variables of age, sex, BMI, ASA, previous abdominal surgery, complicated or uncomplicated diverticulitis, and type of surgery were considered. Post operative variables considered were operative time, bleeding, return of bowel function, and hospital stay. No factor was identified as predictive of conversión. There was a statistically significant difference between both groups when surgical time (p = 0.0030 and operative bleeding (p = 0.0272 were compared. Conclusions: We failed to identify a single factor predictive of conversión to an open procedure. We think it is more probable that a confluence of different variables lead to this result. The patients in whom the conversión was performed had more bleeding and prolonged surgical times, which makes them more prone to post operative complications.

    Full Text Available Ehlers-Danlos syndrome (EDS is a group of inherited connective tissue disorders caused by collagen synthesis defects. EDS type IV, or vascular EDS, is caused by loss-of-function mutations in the type III pro-collagen gene (COL3A1. Common complications of EDS type IV include gastrointestinal bleeding and bowel perforations, posing diagnostic and therapeutic dilemmas for both surgeons and gastroenterologists. Here, we describe a complicated case of EDS type IV in a 35-year-old caucasian female who presented with overt gastrointestinal bleeding. The patient had a prior history of spontaneous colonic perforation, and an uncomplicated upper endoscopy was performed. A careful ileoscopy was terminated early due to tachycardia and severe abdominal pain, and a subsequent computed tomography scan confirmed the diagnosis of ileal perforation. The patient was managed conservatively, and demonstrated daily improvement. At the time of hospital discharge, no further episodes of gastrointestinal blood loss had occurred. This case highlights the benefit of conservative management for EDS patients with gastrointestinal hemorrhage. It is recommended that surgical treatment should be reserved for patients who fail conservative treatment or in cases of hemodynamic instability. Finally, this case demonstrates the necessity for a higher threshold of operative or endoscopic interventions in EDS type IV patients.

  18. 14C-lactose breath tests during pelvic radiotherapy: the effect of the amount of small bowel irradiated

    International Nuclear Information System (INIS)

    Thirty patients who were undergoing pelvic radiotherapy had 14C-lactose breath tests performed in the first and fifth weeks of treatment. In Group I (21 patients), a significant portion of the small intestine was irradiated, and in Group II (9 patients), only a small portion of the small intestine was irradiated. In Group I, the average reductions in the excretion of ingested 14C between the first- and fifth-week tests were 41.5% at 1/2 hour postingestion (p less than 0.05), and 21.8% at 1 hour postingestion (p less than 0.05). In Group II, the percentage reductions were 11.8% and 3.7% at 1/2 and 1 hour, respectively (p greater than 0.05). The data suggest that lactose malabsorption is a factor in the etiology of the nausea, vomiting, and diarrhea experienced by patients who are undergoing pelvic radiotherapy, and that the amount of bowel included in the treatment volume significantly influences the degree of malabsorption

    Background and study aims: The clinical utility of computed virtual chromoendoscopy with flexible spectral imaging color enhancement (FICE) in capsule endoscopy (CE) remains controversial. To clarify the clinical utility of FICE-enhanced CE in evaluating small bowel lesions, we quantitatively assessed white light (WL), FICE, and blue mode (BM) images and examined the sensitivity of these 3 imaging modes of small-bowel lesions from patients who underwent CE. Methods: The CIELAB color difference (?E) and visual analogue scales (VAS) were measured in 261?CE images (3 different lesion categories) using WL and FICE set 1, 2, and 3, and BM images, respectively. Three endoscopists reviewed CE videos with WL, 3 FICE mode settings, and BM, and compared the sensitivity and detectability for small intestinal diseases from 50 patients who underwent CE. Results: In the assessment of visibility in the 152 vascular lesion images, the ?E and VAS of FICE set 1, 2, and BM images were significantly higher than that of WL images. In 88 erosion/ulceration images, the ?E and VAS of FICE set 1 and 2 images were significantly higher than that of WL images. In 21 tumor images, there were no significant differences in ?E among these modalities. When analyzed on a per-patient basis, FICE settings 1 and 2 had the highest sensitivity (100?%) and specificity (97.3?–?100?%) for vascular lesions. As for erosive/ulcerative lesions, FICE setting 2 had the highest sensitivity (100?%) and specificity (97.2?%). For tumors or polyps, WL had the highest sensitivity (90.9?%) and specificity (87.1?%). In per-lesion analysis, FICE settings 1 and 2 showed significantly superior detection ability over WL for vascular lesions. In the detection of erosive/ulcerative lesions, FICE setting 2 was significantly superior to WL. In tumor images, there was no significant improvement with any of the settings relative to WL images. Conclusions: FICE is most useful for improving CE image quality and detection in cases of angioectasia and erosion/ulceration of the small intestine. PMID:26135265

  20. A randomised, controlled study of small intestinal motility in patients treated with sacral nerve stimulation for irritable bowel syndrome

    2014-01-01

    BACKGROUND: Irritable bowel syndrome (IBS) is among the most common gastrointestinal disorders worldwide. In selected patients with severe diarrhoea-predominant or mixed IBS subtypes sacral nerve stimulation (SNS) alleviates IBS-specific symptoms and improves quality of life. The mode of action, however, remains unknown. The present study aimed to evaluate the effect of SNS on small intestinal motility in IBS patients. METHODS: Twenty patients treated with SNS for severe diarrhoea-predominant or mixed IBS were included in a randomised, controlled, crossover study. The neurostimulator was turned ON or OFF for the first one month and then to the opposite setting for the next month. Gastrointestinal transit patterns were investigated with the Motility Tracking System-1 (MTS-1) at the end of each the ON and OFF period. Primary endpoint was change in the velocity of the magnetic pill within the small intestine. Statistical testing was performed with Wilcoxon's rank sum test and Fisher's exact test. RESULTS: The median velocity of the magnetic pill through the small intestine in the fasting state was not significantly different between periods with and without SNS (Group ON-OFF: median change 0 m/h (range -1.07, 0.63), Group OFF-ON: median change 0.27 m/h (range -0.59, 1.12)) (p = 0.25). Neither, was the median velocity of the magnetic pill through the small intestine in the postprandial state significantly different between periods with and without SNS (Group ON-OFF: median change -0.13 m/h (range -0.46, 0.23), Group OFF-ON: median change 0.015 m/h (range -0.48, 0.59)) (p = 0.14). CONCLUSION: Even though SNS may reduce symptoms of diarrhoea-predominant and mixed IBS, it has no detectable effect on small intestinal transit patterns.

  2. Patients' selection for treatment of caliceal diverticular stones with extracorporeal shock wave lithotripsy

    International Nuclear Information System (INIS)

    Symptoms of caliceal diverticular stones are commonly associated with pain, recurrent urinary tract infection and hematuria. The aim of this study is to select the proper patient for the application of more successful extracorporeal shock wave lithotripsy(ESWL) as a treatment of caliceal diverticular stone. 16 patients with caliceal diverticular stones were treated with ESWL, and all patients had single caliceal diverticulum. The diagnosis of caliceal diverticulum with stones was made by intraveneous pyelography to all patients. On these intravenous pyelogram, we also classified diverticular type, whether the diverticular neck is connected with urinary tract patently, diverticular site and stone number and size. All patients were followed after ESWL by plain film of the kidneys, ureters and bladder and interviewed. Of all patients 44% was shown stone-free completely, also 83% was rendered symptom-free. All patients whose diverticular neck connected with urinary tract patently on the intraveneous pyelogram became stone-free. Of solitary stone 60% and multiple stones (more than 2) 17% became symptom-free. The patients with infection before ESWL 75% had residual stones, of these patients 33% had slightly flank pain, and 25% of patients with stones recurred become stone-free. We propose that more successful ESWL for patients with caliceal diverticular stones select satisfactory patients including that the diverticular neck is connected with urinary tract patently, solitary stone and no infection simultaneously

    To evaluate the efficacy of a belly-board device (BBD) in reducing the volume of small bowel during four-field pelvic irradiation. Materials and Methods: Twenty-two cancer patients (14 uterine cervical cancer, 6 rectal cancer, and 2 endometrial cancer) scheduled to receive pelvic irradiation were selected for this study. Two sets of CT images were taken with and without the belly-board device using the Siemens 16 channel CT scanner. All patients were set in the prone position. The CT images were transferred to a treatment planning system for dose calculation and volume measurements. The external surfaces of small bowel and the bladder were contoured on all CT scans and the 4-pelvic fields were added. The dose-volume-histogram of the bladder and small bowel, with and without the BBD, were plotted and analyzed. Results: In all patients, the total small bowel volume included in the irradiated fields was reduced when the BBD was used. The mean volume reduction was 35% (range, 1-79%) and was statistically significant (p<0.001). The reduction in small bowel volume receiving 10-100% of the prescribed dose was statistically significant when the BBD was used in all cases. Almost no change in the total bladder volume involved was observed in the field (<8 cc, p=0.762). However, the bladder volume receiving 90% of the prescribed dose was 100% in 15/22 patients (68%) and 90-99% in 7/22 patients (32%) with the BBD. In comparison, the bladder volume receiving 90% of the prescribed dose was 100% in 10/22 patients (45%), 90-99% in 7/22 patients (32%), and 80-89% in 5/22 patients (23%) without the BBD. When the BBD was used, an increase in the bladder volume receiving a high dose range was observed Conclusion: This study shows that the use of a BBD for the treatment of cancer in the pelvic area significantly improves small bowel sparing. However, since the BBD pushed the bladder into the treatment field, the bladder volume receiving the high dose could increase. Therefore it is recommended to be considerate in using the BBD when bladder damage is of concern.

  4. Evaluation of small-bowel transit for solid and liquid test meal in healthy men and women

    International Nuclear Information System (INIS)

    Evaluation of severe functional gastrointestinal motility disorders requires an investigation of the entire gastrointestinal tract. This should be possible with a single radionuclide imaging study. The purpose of this study was (1) to define normal values of small-bowel transit in men and women and (2) to assess a possible difference between gender or test meal, since it has been shown that women have slower gastric emptying than men, and gastric emptying of solids is slower than liquids. A standard gastric-emptying test for a solid (technetium-99m sulphur colloids, 230 Kcal) and liquid (indium-111 DTPA water) test meal was performed in 12 healthy male and 12 healthy female volunteers. After 135 min, the volunteer was place in the supine position for static imaging of the abdomen every 15 min for 6 h. Decay and crossover-corrected geometric mean gastric-emptying data were fit to a modified power exponential function to determine the 10% stomach emptying time for solids and liquids separately. An ROI was drawn around the caecum and ascending colon to determine the arrival time of at least 10% of the solid and liquid test meal. Ten percent small-bowel transit time (10% SBTT) and orocaecal transit time (OCTT) were calculated. The OCTT for males and females, respectively for solids and liquids, are 294.6±18.8; 301.3±24.5; 294.6±18.8 and 301.3±24.5 min. The 10% SBTT for males and females, respectively for solids and liquids, are 280.3±18.4; 280.6±24.0; 288.2±18.9 and 297.4±24.4 (means±SEM) min. We observed a simultaneous transfer of solids and liquids from the terminal ileum to caecum (correlation coefficient 0.90). There is no statistically significant difference in SBTT between gender or solids and liquids. In contrast to the gastric-emptying time, the SBTT of solids and liquids were not significantly different nor was a gender difference found. Determination of the OCTT seems to be the simplest and most accurate approach to measure SBTT. Since ileocaecal transfer occurs as a bolus phenomenon, a 111In-labelled test meal can also be used for the determination of colon transit in a single imaging study protocol. (orig.)

    Full Text Available Diverticular disease (DD of the colon is very common in developed countries and is ranked the fifth most important gastrointestinal disease worldwide. The management of acute diverticulitis without perforation and peritonitis is still debated. Health related quality of life (HRQL, subjectively perceived by patients, is becoming a major issue in the evaluation of any therapeutic intervention, mainly in patients with chronic disease. To date only a few published studies can be found on Medline examining HRQL in patients with DD. The aim of this study was to review the impact of surgery for DD on HRQL. All Medline articles regarding HRQL after surgery for colonic DD, particularly those comparing different surgical approaches, were reviewed. DD has a negative impact on HRQL with lower scores in bowel function and systemic symptoms. Both surgery-related complications and disease activity have a significant impact on patients’ HRQL. While no significant differences in HRQL between different operations for DD in non-randomized studies were revealed, the only prospective double-blind randomized study that compared laparoscopic and open colectomy found that patients undergoing laparoscopic colectomy had significantly reduced major postoperative complication rates and subsequently had better HRQL scores. Formal assessment of HRQL could be a good instrument in the selection of appropriate patients for elective surgery as well as in the assessment of surgical outcome.

    Barium contrast radiography is a conventional procedure aimed at revealing lesions of the alimentary tract using barium sulfate on X-ray irradiation. Although it is widely used in clinics, adverse effects and complications are observed, such as anaphylaxis, granuloma, fecalithes, abdomen-leaking, embolism, bacterial contamination, and aspiration. We report a case of death due to a massive barium sulfate aspiration resulted from an air-barium double contrast enema radiography. A 25-year-old female patient was hospitalized with symptoms of abdominal distention, nausea, vomiting and diarrhea for three days. A progressive respiratory distress presented only 1h after a small bowel air-barium double contrast enema. The patient died 11h later. The result of autopsy revealed the cause of death to be severe chemical pneumonitis induced by gastric fluid which was aspirated into her lungs. Barium sulfate is generally recognized to be chemically inert for the respiratory system, but a mixture of barium sulfate with gastric contents is fatal. Here we intend to suggest that, when determining the potential cause of death, medical examiners should consider a patient's status quo as well as the possible adverse effects and complications caused by the barium sulfate preparation during gastrointestinal radiography.

  11. Limitations of indirect methods of estimating small bowel transit in man

    International Nuclear Information System (INIS)

    Experiments were carried out in healthy volunteers to explore the utility of a new [14C]lactulose breath test for measuring small intestinal transit time in man and to use this procedure to test whether two antidiarrheal agents, codeine and clonidine, alter small intestinal transit time during digestion of a liquid meal. In an initial validation study performed in 12 subjects, a liquid test meal containing 10 g [14C]lactulose was administered and the colonic entry time estimated from the time course of 14CO2 excretion in breath compared with that of H2 excretion. There was a fair correlation (r = 0.77; P less than 0.001) between results obtained by the two methods; both methods gave similar results, but 14CO2 output was delayed when compared to H2 output and was incomplete. The meal also contained xylose and [13C]glycine, permitting the duodenal entry time of the meal to be estimated by the appearance of xylose in blood and 13CO2 in breath, respectively. The same liquid meal was then used to examine the effect on small intestinal transit time (colonic entry time minus duodenal entry time) of codeine or clonidine. 99Tc-sulfur colloid was also added to the meal to permit a comparison of small intestinal transit estimated by imaging with that estimated by the 14CO2-lactulose breath test. 99Tc radioactivity appeared in the cecum (as assessed using gamma scintigraphy) about 2 hr before 14CO2 radioactivity appeared in breath; the correlation between transit time estimated by the two methods was moderate (r = 0.61; P less than 0.05). Based on the [14C]lactulose data, small intestinal transit time ranged from less than 1 to 3 hr for a liquid meal containing 10 g lactulose; within-subject variation was considerably less than between-subject variation

  13. Correlation between bladder volume and irradiated dose of small bowel in CT-based planning of intracavitary brachytherapy for cervical cancer

    International Nuclear Information System (INIS)

    The objective of this study was to quantify the effect of bladder volume on the dose distribution of intracavitary brachytherapy in computed tomography-based treatment planning for cervical cancer. Ten patients with cervical cancer were treated with high-dose rate radiation brachytherapy. For the three-dimensional analysis, pelvic computed tomographic scans were obtained from patients with indwelling catheters in place and from patients who received 50, 100, 150 and 200 cc injections of sterile water into their bladders ('200 cc' was defined as a full bladder). Additionally, scans were made in the prone position with the full bladder. Bladder fullness significantly affected the dose to the small bowel and bladder. The median of maximal doses to the small bowel was significantly greater with an empty bladder in all factors of hot spot (480 vs. 256 cGy on D-2cc). Although dosimetry revealed lower doses for larger volumes of bladder (D-50 and V-25%), the median maximal dose to the bladder was significantly greater with a full bladder (420 vs. 775 cGy on D-2cc). The rectosigmoid doses were not affected by bladder distension (476 vs. 467 cGy on D-2cc). After changing to the prone position, the hot spot dose of small bowel did not change but that of the bladder significantly decreased, although this procedure was very difficult. An increase in bladder volume resulted in a significant reduction in the hot spot dose of the small bowel at the expense of an increase in that of the bladder without changing the dose distribution of the rectosigmoid.

  20. Treatment with a belly-board device significantly reduces the volume of small bowel irradiated and results in low acute toxicity in adjuvant radiotherapy for gynecologic cancer: results of a prospective study

    International Nuclear Information System (INIS)

    Background and purpose: To determine whether treatment prone on a belly-board significantly reduces the volume of small bowel irradiated in women receiving adjuvant radiotherapy for gynecologic cancer, and to prospectively study acute small bowel toxicity using an accepted recording instrument. Material and methods: Thirty-two gynecologic patients underwent simulation with CT scanning supine and prone. Small bowel was delineated on every CT slice, and treatment was prone on the belly-board using 3-5 fields-typically Anterior, Right and Left Lateral, plus or minus Lateral Boosts. Median prescribed dose was 50.4 Gy and all treatments were delivered in 1.8 Gy fractions. Concomitant Cisplatin was administered in 13 patients with cervical carcinoma. Comparison of small bowel dose-volumes was made between supine and prone, with each subject acting as their own matched pair. Acute small bowel toxicity was prospectively measured using the Common Toxicity Criteria: Version 2.0. Results: Treatment prone on the belly-board significantly reduced the volume of small bowel receiving ?100; ?95; ?90; and ?80% of the prescribed dose, but not ?50%. This was found whether volume was defined in cubic centimeters or % of total small bowel volume. Of 29 evaluable subjects, 2 (7%) experienced 1 episode each of grade 3 diarrhoea. All other toxicity events were grade 2 or less and comprised diarrhoea (59%), abdominal pain or cramping (48%), nausea (38%), anorexia (17%), vomiting (10%). There were no Grade 4 events and no treatment days were lost due to toxicity. Conclusions: Treatment prone on a belly-board device results in significant small bowel sparing, during adjuvant radiotherapy for gynecologic cancer. The absence of Grade 4 events or Treatment Days Lost compares favorably with the published literature

Materials and methods: Thirteen patients (five men, eight women; mean age 41.2 years; range 29-56) were imaged on a 1.5-T MR scanner (Sonata, Siemens Medical) with standard MR sequences after having ingested 1000 ml of a 3% mannitol solution. Subsequently, high resolution 3D gradient-echo (volumetric interpolated breath-hold examination = VIBE) data sets were obtained pre-contrast and 20-40 s, 60-80 s, and 120-140 s after i.v. Gd-DOTA administration (0.2 mmol/kg). Signal enhancement was measured on single slices both in normal and histologically confirmed (12/13) inflamed small bowel wall segments as well as in the aorta, the psoas muscle, and the background to calculate signal-to-noise (SNR) and contrast-to-noise ratios (CNR). Results: Small bowel wall enhancement was significantly higher (p < 0.05) in inflamed compared to normal segments at 20-40 s (SNR inflamed: 58.7 {+-} 33.8 vs normal: 36.0 {+-} 19.8; p = 0.048; CNR inflamed: 34.8 {+-} 23.4 vs normal: 16.3 {+-} 11.2; p = 0.017) and at 60-80 s (SNR: 60.3 {+-} 25.1 vs 41.9 {+-} 20.0; p = 0.049; CNR: 34.9 {+-} 15.1 vs 19.3 {+-} 13.2; p = 0.01) after i.v. contrast administration, respectively. Even at 120-140 s CNR was still increased in inflamed segments (33.7 {+-} 16.0 vs 18.1 {+-} 13.2; p = 0.04), while differences in SNR did not attain statistical significance (63.0 {+-} 26.2 vs 45.3 {+-} 23.3; p = 0.15). Conclusion: In active Crohn's disease, histologically confirmed inflamed small bowel wall segments demonstrate a significantly increased early uptake of gadolinium on 3D VIBE sequences compared to normal small bowel segments.

    Full Text Available Background: Carcinoid tumors are slowly growing malignant neoplasms associated with an indolent clinical course. About 60% of such tumors are located within the gastrointestinal tract. Case Report: We describe an unusual case of small bowel obstruction associated with of a carcinoid tumor of the ileum. A 70-year-old woman was presented with abdominal pain, vomiting, and clinical signs of mechanical bowel obstruction. X-ray and CT-scan of the abdomen showed hydroaeric levels and the presence of intraluminal hyper-dense “stones”, presumably of gallbladder origin. A diagnostic laparotomy revealed that a large part of the final ileus was edematous, with prominent evidence of intestinal loop adhesions. The edematous part of the ileum was resected. Incision of the intestinal wall revealed a 2-cm soft mass at 8 cm from the ileocecal valve, where the presence of ten fruit pits obstructed the intestinal cavity. Histopathological examination confirmed the diagnosis of a carcinoid tumor. Conclusion: An interesting case of small-bowel obstruction with a double cause is presented: an ileal carcinoid and fruit pit bezoars. The pathophysiology of the obstruction is discussed.

    Full Text Available INTRODUÇÃO: As fístulas enterovesicais (FEV) são comunicações patológicas entre a bexiga e as alças intestinais pélvicas. Trata-se de uma rara complicação decorrente de doenças inflamatórias e neoplásicas da pelve, além de casos resultantes de iatrogenia, e associa-se a altos índices de morbimortali [...] dade. RELATO DO CASO: Trata-se de um paciente de 61 anos com um quadro de dor e distensão abdominal, vômitos, parada de eliminação de fezes e flatos. APP: Hipertenso, diabético, com antecedentes de disfunção vesical e infecções do trato urinário de repetição (ITUr) nos últimos três anos. Por meio da realização de ressonância magnética de abdômen e pelve, diagnosticou-se FEV associada à doença diverticular (DDC) do sigmoide. A conduta estabelecida consistiu em colectomia parcial com rebaixamento de colo e cistectomia parcial com colocação cirúrgica de cateter duplo jota à esquerda. DISCUSSÃO: Embora consista de afecção primária do trato digestivo, normalmente o paciente com DDC associada a FEV procura atendimento médico em decorrência de queixas do trato urinário. Nesse caso, a demora no diagnóstico fez com que a queixa principal fosse do trato digestivo e com antecedentes de queixas urinárias. CONCLUSÃO: Apesar de pouco frequente, a ocorrência de ITUr associada à DDC deve ser sempre considerada no diagnóstico diferencial das ITUr pela alta morbimortalidade. Abstract in english INTRODUCTION: Enterovesical fistula are pathological connections between the bladder and pelvic intestinal segments. It consists of a rare complication of neoplastic and inflammatory pelvic disorders, in addition to iatrogenic or traumatic injuries, and correlates with both high morbidity and mortal [...] ity indexes. CASE REPORT: Male patient, 61 years old, admitted at the hospital clinics featuring abdominal pain and distension, vomiting and fecal retention. Patient's pathological precedents include high blood pressure, diabetes mellitus, vesical dysfunction and recurrent urinary tract infection on the past three years. Magnetic resonance imaging of abdomen and pelvis revealed enterovesical fistula in association with colon diverticular disease of the sigmoid. Management of choice consisted of partial colectomy with bowel lowering and partial cystectomy with surgical double-J stent insertion. DISCUSSION: Although consisting of a gastrointestinal primary affection, patients with enterovesical fistula usually search for medical help charging urinary tract features. In this particular case, our patient was admitted with gastrointestinal symptoms, reasoned by diagnostic delay, as the patient had already attended at multiple centers with urinary symptoms. CONCLUSION: Despite being an unusual affection, recurrent urinary tract infection associated with colon diverticular disease must always be considered at differential diagnosis of recurrent urinary tract infection as it concurs with high morbidity and mortality.

    Full Text Available Renal cell carcinoma metastasis to the small intestine is a rare condition. It usually results in gastrointestinal bleeding and it could happen many years after the diagnosis with renal cell cancer. Treatment includes surgery as well as targeted agents such as tyrosine kinases. We report here the case of an 82-year-old man with a past medical history of high-grade renal cell carcinoma and right nephrectomy 6 years earlier, who presented with recurrent episodes of syncope and black stools. He underwent esophagogastroduodenoscopy (EGD and colonoscopy without evident source of bleeding. Video capsule endoscopy (VCE showed three bleeding lesions in the jejunum and ileum. Push enteroscopy revealed a proximal jejunum bleeding mass that was suspicious for malignancy. Histopathology demonstrated poorly differentiated carcinoma. Given the patient’s history of high-grade renal cell carcinoma, and similarity of histologic changes to the old renal cell cancer specimen, metastatic renal cell carcinoma was felt to be the responsible etiology.

    2002-01-01

    Small bowel carcinoid tumor (SBC) is a rare disease of unknown etiology but with an age-, sex-, and place-specific occurrence that may indicate an occupational origin. A European multicenter population-based case-control study was conducted from 1995 through 1997. Incident SBC cases between 35 and 69 years of age (n = 101) were identified, together with 3335 controls sampled from the catchment area of the cases. Histological review performed by a reference pathologist left 99 cases for study; 84 cases and 2070 population controls were interviewed. The industries most closely associated (a twofold or more odds ratio [OR]) with SBC, taking into account a 10-year time lag after exposure were, among women, employment in wholesale industry of food and beverages (OR, 8.2; 95% confidence interval [CI], 1.9 to 34.9]) and among men, manufacture of motor vehicle bodies (OR, 5.2; 95% CI, 1.2 to 22.4), footwear (OR, 3.9; 95% CI, 0.9 to 16.1), and metal structures (OR, 3.3; 95% CI, 1.0 to 10.4). The identified high-risk occupations with an OR above 2 were shoemakers, structural metal preparers, construction painters and other construction workers, bookkeepers, machine fitters, and welders (men). The OR for regular occupational use of organic solvents for at least half a year was 2.0 (95% CI, 1.0 to 4.2). Exposure to rust-preventive paint containing lead was suggested as another potential occupational exposure (OR, 9.1; 95% CI, 0.8 to 107). This explorative study suggests an association between certain occupational exposures and SBC, but some of these associations could be attributable to chance. All findings should be regarded as tentative.

    Full Text Available Abstract Background A strong dose-volume relationship exists between the amount of small bowel receiving low- to intermediate-doses of radiation and the rates of acute, severe gastrointestinal toxicity, principally diarrhea. There is considerable interest in the application of highly conformal treatment approaches, such as intensity-modulated radiation therapy (IMRT, to reduce dose to adjacent organs-at-risk in the treatment of carcinoma of the rectum. Therefore, we performed a comprehensive dosimetric evaluation of IMRT compared to 3-dimensional conformal radiation therapy (3DCRT in standard, preoperative treatment for rectal cancer. Methods Using RTOG consensus anorectal contouring guidelines, treatment volumes were generated for ten patients treated preoperatively at our institution for rectal carcinoma, with IMRT plans compared to plans derived from classic anatomic landmarks, as well as 3DCRT plans treating the RTOG consensus volume. The patients were all T3, were node-negative (N = 1 or node-positive (N = 9, and were planned to a total dose of 45-Gy. Pairwise comparisons were made between IMRT and 3DCRT plans with respect to dose-volume histogram parameters. Results IMRT plans had superior PTV coverage, dose homogeneity, and conformality in treatment of the gross disease and at-risk nodal volume, in comparison to 3DCRT. Additionally, in comparison to the 3DCRT plans, IMRT achieved a concomitant reduction in doses to the bowel (small bowel mean dose: 18.6-Gy IMRT versus 25.2-Gy 3DCRT; p = 0.005, bladder (V40Gy: 56.8% IMRT versus 75.4% 3DCRT; p = 0.005, pelvic bones (V40Gy: 47.0% IMRT versus 56.9% 3DCRT; p = 0.005, and femoral heads (V40Gy: 3.4% IMRT versus 9.1% 3DCRT; p = 0.005, with an improvement in absolute volumes of small bowel receiving dose levels known to induce clinically-relevant acute toxicity (small bowel V15Gy: 138-cc IMRT versus 157-cc 3DCRT; p = 0.005. We found that the IMRT treatment volumes were typically larger than that covered by classic bony landmark-derived fields, without incurring penalty with respect to adjacent organs-at-risk. Conclusions For rectal carcinoma, IMRT, compared to 3DCRT, yielded plans superior with respect to target coverage, homogeneity, and conformality, while lowering dose to adjacent organs-at-risk. This is achieved despite treating larger volumes, raising the possibility of a clinically-relevant improvement in the therapeutic ratio through the use of IMRT with a belly-board apparatus.

  10. Biomechanical assay for increased murine small bowel stiffness following single and fractionated x-radiation and hyperthermia treatments

    International Nuclear Information System (INIS)

    In C3H mice, 10-15 mm of functional jejunum was selectively and uniformly treated with x-rays followed by 440C waterbath heating while remaining within the peritoneal cavity. Acute deaths were 5-10% for 1- and 15-20% for 3-fraction (72 h interval) studies, with hyperthermia following each x-ray fraction by 10 min. At various times post-treatment, force-extension records were taken from excised bowel using a tensile testing machine to accomplish standard preconditioning cycles of stretch and relaxation followed by stretch to rupture. Late deaths were related to bowel stiffness; linear dose-response (DR) relations spanning 6 Gy per fraction and a doubling of bowel stiffness were possible below the lethal stiffness level. The x-ray-plus-hyperthermia DR was parallel to x-ray-only DR. At 2 months post-treatment 440 15' each fraction displaced the x-ray DR by 7Gy and 14 Gy, and calculated thresholds for stiffness increase were 10.5 and 6 Gy per fraction (x-only) and 3.5 and 1.5 Gy per fraction (X + ?) in the 1- and 3-fraction studies, respectively. Hyperthermia alone had no effect. At x-ray doses causing lethal stiffness, the TER was 1.6 in the 1- and 3-fraction studies. This fractionation protocol did not reduce the risk to bowel from supplementing x-rays with heat

    Full Text Available RACIONAL: Fato de observação não rara, é o encontro de refluxo cecoileal durante realização de enema opaco. As causas e conseqüências deste achado têm sido pouco estudadas. OBJETIVOS: Sabendo que a junção ileocecal exerce função de barreira e proteção contra a invasão do delgado pela flora colônica, [...] realizou-se o presente estudo com a finalidade de investigar se existe contaminação ileal em indivíduos com refluxo cecoileal ao enema opaco. MÉTODOS: Investigaram-se 36 indivíduos, 30 mulheres e 6 homens, idade média de 54 anos, 25 com e 11 com ausência refluxo cecoileal. Todos submetidos a pesquisa de contaminação bacteriana do delgado por intermédio de teste respiratório com lactulose-H2 e a determinação do tempo de trânsito orocecal por meio de biossusceptometria de corrente alternada. A caracterização da contaminação do delgado foi baseada no encurtamento do tempo de trânsito orocecal medido pelo teste da lactulose-H2. RESULTADOS: A comparação dos valores basais do H2, do tempo de trânsito orocecal-H2 e tempo de trânsito orocecal-biossusceptometria de corrente alternada não diferiram estatisticamente entre os grupos com e sem refluxo cecoileal. Quando comparados os tempo de trânsito orocecal-H2 e tempo de trânsito orocecal-biossusceptometria, foi observado aumento de tendência de redução do primeiro em relação ao último nos grupos com refluxo cecoileal e correlação significante entre os dois métodos apenas no grupo-controle, inexistindo nos com refluxo cecoileal. CONCLUSÃO: Encurtamento do tempo de trânsito orocecal-H2 e sua perda de correlação com o tempo de trânsito orocecal-biossusceptometria observado em indivíduos com refluxo cecoileal, sugerem comportamento diferenciado deste grupo em relação ao grupo-controle. Possível explicação para as diferenças registradas entre os grupos, seria a presença de flora anômala nos indivíduos com refluxo cecoileal. Abstract in english BACKGROUND: The observation of cecoileal reflux to barium enema is not rare; however, its causes and consequences have not been widely investigated. Considering that ileocecal junction exerts a function as barrier to invasion of bacteria from colon to small bowel, it seems interesting to study the i [...] ntestinal microflora in subjects carrying cecoileal reflux. AIMS: This study aims at evaluating the ileal flora in individuals with cecoileal reflux. METHODS: A group of 36 subjects comprising 30 females and 6 males with a mean age of 54 years was assessed. Twenty-five individuals with cecoileal reflux and 11 without cecoileal reflux were submitted to small intestine contamination evaluation through the breath test with lactulose-H2 and measurement of the orocecal transit time by means of alternate current biosusceptometry. Small intestine bacterial overgrowth was characterized by orocecal transit time-H2 shortening. RESULTS: Comparison of basal H2, orocecal transit time-H2 and orocecal transit time-alternate current biosusceptometry measurements did not statistically differ between the groups with and without cecoileal reflux. Orocecal transit time-H2 was significantly smaller than orocecal transit time-alternate current biosusceptometry, particularly in individuals with cecoileal reflux. A significant correlation between the two methods was observed only in relation to control, not existing in relation to cecoileal reflux group. CONCLUSIONS: Smaller orocecal transit time-H2 and the loss of correlation with orocecal transit time-alternate current biosusceptometry observed in the individuals with cecoileal reflux suggest a differentiated behavior for such group relative to control, which could be associated with small intestine bacterial overgrowth.

    To retrospectively investigate the added value of diffusion-weighted MR imaging (DWI) for detecting mesenteric small bowel tumours (MSBTs) via MR-enterography. MR-enterographies of 98 patients with suspected MSBTs were blindly analyzed by two independent readers for the presence of MSBTs. Four imaging sets including ''standard'' (Haste and TrueFisp), ''standard + DWI,'' ''standard + gadolinium-enhanced'' and ''standard + DWI + gadolinium-enhanced'' were reviewed. Diagnostic performance of different readings were compared with McNemar's test. Twenty-nine MSBTs were pathologically confirmed. For R1 (junior radiologist) sensitivity, specificity, PPV, NPV and accuracy for the detection of MSBTs via standard MRI were 52 % [95 % CI: 34 %-70 %] (15/29), 94 % [95 % CI: 89 %-100 %] (65/69), 79 % [95 % CI: 61 %-97 %] (15/19), 82 % [95 % CI: 74 %-91 %] (65/79) and 82 % [95 % CI: 74 %-89 %] (80/98), respectively. For R2 (senior radiologist) they were 76 % [95 % CI: 60 %-91 %] (22/29), 96 % [95 % CI: 91-100 %] (66/69), 88 % [95 % CI: 75 %-100 %] (22/25), 90 % [95 % CI: 84 %-97 %] (66/73) and 90 % [95 % CI: 84 %-96 %] (88/98), respectively. Adding DWI they were 72 % [95 % CI: 56 %-89 %] (21/29), 91 % [95 % CI: 85 %-98 %] (63/69), 78 % [95 % CI: 62 %-94 %] (21/27), 89 % [95 % CI: 81 %-96 %] (63/71) and 87 % [95 % CI: 80 %-94 %] (85/98) for R1 and 79 % [95 % CI: 65 %-94 %] (23/29), 97 % [95 % CI: 93 %-100 %] (67/69), 92 % [95 % CI: 81 %-100 %] (23/25), 92 % [95 % CI: 86 %-98 %] (67/73) and 92 % [95 % CI: 86 %-97 %] (90/98) for R2. Sensitivities for tumour detection were higher after adding DWI to standard MRI, although only for R1 was this significant (P = 0.03). Adding DWI to standard + gadolinium-enhanced MRI did not significantly increase MR performance. DWI improves MSBT detection via MR-enterography compared to standard unenhanced MR-enterography, especially for unexperienced readers. (orig.)

    The onset of Crohn disease (CD) can occur in childhood. Imaging, which often involves radiation, is frequent in CD both for disease diagnosis and follow-up. However, information regarding radiation dose for contemporary CT and fluoroscopy is not available for determining the cost/benefit ratio for imaging strategies. To compare effective dose (ED) for small-bowel follow-through (SBFT) and abdomen/pelvis MDCT in pediatric CD. Average fluoroscopic time and number of radiographs were obtained for 30 consecutive pediatric SBFTs. The numbers of SBFTs and CT scans performed per child among children with CD (1990-2005) were determined. The ED was determined (ICRP 60, 10-year-old phantom, MOSFET) for a 5-min fluoroscopy examination of the central abdomen and right lower quadrant (110 kVp, 0.3 mA) and pelvis (110 kVp, 0.35 mA). The ED for a 16-slice abdomen/pelvis MDCT scan was determined using the 10-year-old protocol: 16 x 1.25 mm, pitch 1.375, 27.5 mm/rotation, 0.5 s, 140 kVp, 85 mA. A total of 176 children with CD underwent imaging, averaging 1.2 SBFTs and 1.1 CT scans. On average SBFT took 5.1 min with 3.3 abdominal radiographs. The EDs (mSv) for a 5-min fluoroscopy were 0.15 for the central abdomen, 0.35 for the right lower quadrant, and 0.56 for the pelvis, yielding an average ED for SBFT (5-min fluoroscopy, 3.3 abdominal radiographs) of 1.8-2.2 mSv. The ED for MDCT was 3.48 mSv. Although the ED for MDCT might be up to twice that for SBFT, excessive fluoroscopy time and number of abdominal radiographs can result in actual EDs that are equivalent. Attention must be paid to SBFT technique to minimize radiation dose and to the indication to determine the appropriate examination. (orig.)

    Full Text Available Background and Objective: Celiac is an autoimmune disease that is characterized by an immune-system-related damage in the intestinal tissue after consumption of gluten. There is not any general agreement for gold standard. The Purpose of this study was the evaluation of specificity and sensitivity of anti-endomysial (EMA and anti-tissue transglutaminase (TTG serological test compared to small-bowel biopsy. Material and Methods: In the cross sectional study, we took blood specimen from 1825 patients with gastrointestinal disease. All the samples were tested by TTG and EMA kits using ELISA. The patients were studied in two groups. First, the individuals whom their serologic test was positive but their tissue condition was normal and second, those with positive serologic test with pathologic tissue results that show they have celiac disorder. Results: The mean of EMA and TTG shows that the level of antibodies in group 2 is significantly higher than that of the first group (P ?0.001. There is positive correlation between modified marsh criteria of small-bowel biopsy and the two tests. The Sensitivity of EMA and TTG tests for celiac diagnosis is 92%. The specificity of EMA, TTG tests are 100% and 98.5%, respectively. Conclusion: EMA-IgA serology with cut-off point of more than 66 together with TTG-IgA serology with cut-off point of above 30 can be helpful to distinguish a wide range of patients who need small-bowel biopsy.

    2015-01-01

    Gallstone ileus of the sigmoid colon is an important, though extremely rare, cause of large bowel obstruction. The gallstone often enters the large bowel through a fistula formation between the gallbladder and colon, and impacts at a point of narrowing, causing large bowel obstruction. We describe the case of an 80-year-old woman who presented with features of bowel obstruction. Multiplanar abdominal CT demonstrated a cholecystocolonic fistula in exquisite detail. The scan also showed obstruction of the colon due to a large gallstone impacted just proximal to a stricture in the sigmoid. Owing to inflammatory adhesions and a stricture from extensive diverticular disease, the gallstone could not be retrieved. This frail and elderly woman was treated with a loop colostomy to relieve bowel obstruction. The patient made an uneventful recovery. PMID:26682834

DBE revealed ulcers with stigmata of recent hemorrhage in 6 patients treated by injection of epinephrine diluted at 1:10 000, Dieulafoy-like lesions in 4 patients treated by deploying hemoclips on the vessels, colonic diverticula in 2 patients, and duodenal diverticula in 3 patients, respectively. Of the 2 patients who underwent surgical intervention, 1 had a large diverticulum and was referred by the surgeon for DBE, 1 received endoscopic therapy but failed due to massive bleeding. One patient had a second DBE for recurrent hemorrhage 7 mo later, which was successfully treated with a repeat endoscopy. The mean follow-up time of patients was 14.7 ± 7.8 mo.CONCLUSION: DBE is a safe and effective treatment modality for jejunal diverticular bleeding.

    Videocapsule endoscopy (VCE) has revolutionized our ability to visualize the small bowel mucosa. This modality is a valuable tool for the diagnosis of obscure small bowel Crohn’s disease (CD), and can also be used for monitoring of disease activity in patients with established small-bowel CD, detection of complications such as obscure bleeding and neoplasms, evaluation of response to anti-inflammatory treatment and postoperative recurrence following small bowel resection. VCE could also be an...

    Holte, Kathrine; Nielsen, Kristine Grubbe

    2004-01-01

    PURPOSE: Despite the universal use of bowel preparation before colonoscopy and colorectal surgery, the physiologic effects have not been described in a standardized setting. This study was designed to investigate the physiologic effects of bowel preparation. METHODS: In a prospective study, 12 healthy volunteers (median age, 63 years) underwent bowel preparation with bisacodyl and sodium phosphate. Fluid and food intake were standardized according to weight, providing adequate calorie and oral fluid intake. Before and after bowel preparation, weight, exercise capacity, orthostatic tolerance, plasma and extracellular volume, balance function, and biochemical parameters were measured. RESULTS: Bowel preparation led to a significant decrease in exercise capacity (median, 9 percent) and weight (median, 1.2 kg). Plasma osmolality was significantly increased from 287 to 290 mmol kg(-1), as well as increased phosphate and urea concentrations, whereas calcium and potassium concentrations decreased significantly afterbowel preparation. No differences in plasma or extracellular volumes were seen. Orthostatic tolerance and balance function did not change after bowel preparation. CONCLUSIONS: Bowel preparation has significant adverse physiologic effects, which may be attributed to dehydration. The majority of these findings is small and may not be of clinical relevance in otherwise healthy patients undergoing bowel preparation and following recommendations for oral fluid intake.

  20. Heritability and familial aggregation of diverticular disease : A population-based study of twins and siblings

    DEFF Research Database (Denmark)

    Strate, Lisa L; Erichsen, Rune

    2013-01-01

    BACKGROUND & AIMS: Little is known about the role of heritable factors in diverticular disease. We evaluated the contribution of heritable factors to the development of diverticular disease diagnosed at a hospitalization or outpatient visit. METHODS: Using nationwide patient registries, we identified 142,123 incident cases of diverticular disease diagnosed at a hospitalization (1977-2011) or an outpatient hospital visit (1995-2011) in Denmark, including cases in 10,420 index siblings and 923 twins. We calculated standardized incidence ratios for siblings versus the general population and concordance rates for monozygotic versus dizygotic twin pairs as measures of relative risk (RR). RESULTS: The RR for diverticular disease in siblings of index cases was 2.92 (95% confidence interval [CI], 2.50-3.39) compared with the general population. The RRs were similar irrespective of the sex of the sibling or index case and were particularly strong in siblings of hospitalized cases and cases that underwent surgery. The proband-wise concordance rate for monozygotic twins was double that of dizygotic twins (0.16 [95% CI, 0.11-0.22] vs 0.07 [95% CI, 0.05-0.11], respectively). The RR of diverticular disease in one twin when the other had diverticular disease was 14.5 (95% CI, 8.9-23) for monozygotic twins compared with 5.5 (95% CI, 3.3-8.6) for dizygotic twins. Associations were stronger in female monozygotic twins compared with male twins (tetrachoric correlation, 0.60 [95% CI, 0.49-0.70] vs 0.33 [95% CI, 0.13-0.51]; P = .03 in an analysis stratified by sex and zygosity). We estimate that 53% (95% CI, 45%-61%) of susceptibility to diverticular disease results from genetic factors. CONCLUSIONS: Based on a population-based study in Denmark, genetic factors appear to contribute to development of diverticular disease.

  1. Indications and selection of MR enterography vs. MR enteroclysis with emphasis on patients who need small bowel MRI and general anaesthesia : results of a survey

    Torkzad, Michael R; Masselli, Gabriele

    2015-01-01

    AIMS: To survey the perceived indications for magnetic resonance imaging of the small bowel (MRE) by experts, when MR enteroclysis (MREc) or MR enterography (MREg) may be chosen, and to determine how the approach to MRE is modified when general anaesthesia (GA) is required. MATERIALS AND METHODS: Selected opinion leaders in MRE completed a questionnaire that included clinical indications (MREg or MREc), specifics regarding administration of enteral contrast, and how the technique is altered to accommodate GA. RESULTS: Fourteen responded. Only the diagnosis and follow-up of Crohn's disease were considered by over 80 % as a valid MRE indication. The remaining indications ranged between 35.7 % for diagnosis of caeliac disease and unknown sources of gastrointestinal bleeding to 78.6 % for motility disorders. The majority chose MREg over MREc for all indications (from 100 % for follow-up of caeliac disease to 57.7 % for tumour diagnosis). Fifty per cent of responders had needed to consider MRE under GA. The most commonly recommended procedural change was MRI without enteral distention. Three had experience with intubation under GA (MREc modification). CONCLUSION: Views were variable. Requests for MRE under GA are not uncommon. Presently most opinion leaders suggest standard abdominal MRI when GA is required. MAIN MESSAGES: • Experts are using MRE for various indications. • Requests for MRE under general anaesthesia are not uncommon. • Some radiologists employ MREc under general anaesthesia; others do not distend the small bowel.

    Pediatric patients undergoing small bowel transplantation are susceptible to postoperative CLABSI. SDD directed against enteric microbes is a strategy for reducing CLABSI. We hypothesized that SDD reduces the frequency of CLABSI, infections outside the bloodstream, and allograft rejection during the first 30 days following transplant. A retrospective chart review of 38 pediatric small bowel transplant recipients at CCHMC from 2003 to 2011 was conducted. SDD antimicrobials were oral colistin, tobramycin, and amphotericin B. The incidence of CLABSI, infections outside the bloodstream, and rejection episodes were compared between study periods. The incidence of CLABSI did not differ between study periods (6.9 CLABSI vs. 4.6 CLABSI per 1000 catheter days; p = 0.727), but gram positives and Candida predominated in the first 30 days. Incidence of bacterial infections outside the bloodstream did not differ (p = 0.227). Rejection occurred more frequently during the first month following transplant (p = 0.302). SDD does not alter the incidence of CLABSI, bacterial infections outside the bloodstream, or allograft rejection in the immediate 30 days post-transplantation. However, SDD does influence CLABSI organism types (favoring gram positives and Candida) and Candidal infections outside the bloodstream. PMID:26332092

  5. Danish national guidelines for treatment of diverticular disease

    DEFF Research Database (Denmark)

    Andersen, Jens Christian; Bundgaard, Lars

    2012-01-01

    In order to elaborate evidence-based, national Danish guidelines for the treatment of diverticular disease the literature was reviewed concerning the epidemiology, staging, diagnosis and treatment of diverticular disease in all its aspects. The presence of colonic diverticula, which is considered to be a mucosal herniation through the intestinal muscle wall, is inversely correlated to the intake of dietary fibre. Other factors in the genesis of diverticular disease may be physical inactivity, obesity, and use of NSAIDs or acetaminophen. Diverticulosis is most common in Western countries with a prevalence of 5% in the population aged 30-39 years and 60% in the part of the population > 80 years. The incidence of hospitalization for acute diverticulitis is 71/100,000 and the incidence of complicated diverticulitis is 3.5-4/100,000. Acute diverticulitis is conveniently divided into uncomplicated and complicated diverticulitis. Complicated diverticulitis is staged by the Hinchey classification 1-4 (1: mesocolic/pericolic abscess, 2: pelvic abscess, 3: purulent peritonitis, 4: faecal peritonitis). Diverticulitis is suspected in case of lower left quadrant abdominal pain and tenderness associated with fever and raised WBC and/or CRP; but the clinical diagnosis is not sufficiently precise. Abdominal CT confirms the diagnosis and enables the classification of the disease according to Hinchey. The distinction between Hinchey 3 and 4 is done by laparoscopy or, when not possible, by laparotomy. Uncomplicated diverticulitis is treated by conservative means. There is no evidence of any beneficial effect of antibiotics in uncomplicated diverticulitis, but antibiotics may be used in selected cases depending on the overall condition of the patients and the severity of the infection. Abscess formation is best treated by US- or CT-guided drainage in combination with antibiotics. When the abscess is <3 cm in diameter, drainage may be unnecessary, and only antibiotics should be instituted. The surgical treatment of acute perforated diverticulitis has interchanged between resection and non-resection strategies: The three-stage procedure dominating in the beginning of the 20th century was later replaced by the Hartmann procedure or, alternatively, resection of the sigmoid with primary anastomosis. Lately a non-resection strategy consisting of laparoscopy with peritoneal lavage and drainage has been introduced in the treatment of Hinchey stage 3 disease. Evidence so far for the lavage regime is promising, comparing favourably with resection strategies, but lacking in solid proof by randomized, controlled investigations. In recent years, morbidity has declined in complicated diverticulitis due to improved diagnostics and new treatment modalities. Recurrent diverticulitis is relatively rare and furthermore often uncomplicated than previously assumed. Elective surgery in diverticular disease should probably be limited to symptomatic cases not amenable to conservative measures, since prophylactic resection of the sigmoid, evaluated from presentevidence, confers unnecessary risks in terms of morbidity and mortality to the individual as well as unnecessary costs to society. Any recommendation for routine resection following multiple cases of diverticulitis should await results of randomized studies. Laparoscopic resection is preferred in case of need for elective surgery. When malignancy is ruled out preoperatively, a sigmoid resection with preservation of the inferior mesenteric artery, oral division of colon in soft compliant tissue and anastomosis to upper rectum is recommended. Fistulae to bladder or vagina, or stenosis of the colon may be dealt with according to symptoms and comorbidity. Resection of the diseased segment of colon is preferred when possible and safe; alternatively, a diverting stoma can be the best solution.

  6. The genetic epidemiology of diverticulosis and diverticular disease: Emerging evidence.

    2015-10-01

    Diverticular disease (DD) is one of the most prevalent gastrointestinal disorders. The pathogenesis of diverticulosis and DD is controversially discussed. Current studies call the traditional concept of a fibre-deficient diet causing the development of diverticula into question. Data from two recent twin studies have provided conclusive evidence for a strong genetic component to diverticulosis. Although genomewide association studies have provided new insights into the polygenic architecture of human diseases, genomic research in diverticulosis and DD has just been started. This is an astonishing fact given the high morbidity and mortality of the disease, as well as the substantial economic burden on health care systems. For this review, we provide an update of the molecular pathobiology and summarise recent evidence supporting the hypothesis that distinct, yet unidentified genetic variants contribute to the development of diverticulosis and DD.

Parenteral nutrition-associated liver damage is the most frequent indication for BT, especially in children that are more susceptible than adults to develop this complication. Other accepted indications for BT are irreversible intestinal failure in association with loss of deep venous accesses, life-threatening severe infections associated with the use of central catheters, and those cases of intestinal failure usually leading to early death, such as ultra-short bowel syndromes, refractory diarrheas, and intestinal failure associated to high morbidity and poor quality of life. BT is performed in human clinical practice under three technical modalities: isolated bowel transplant, combined liver-bowel transplant, and multi-visceral transplantation. Currently, refinements of original techniques including reduction of liver and/or intestinal grafts, grafts from living donors, etc., allow for overcoming the different needs as well as increasing the likelihood of having access to transplantation, which is a desirable goal specially in very young or very low-weighted children candidate to liver-bowel transplant. One of the most interesting issues in BT programs is having given access to the Intestinal Rehabilitation Units, which comprise the three therapeutic modalities by means of a multidisciplinary team: nutritional support, pharmacotherapy, and surgery. These Units optimize the outcomes, minimize costs, and allow for offering a management adapted to individual needs.

    Full Text Available A validated questionnaire to assess the impact of small bowel obstructions (SBO on patients’ quality of life was developed and validated. The questionnaire included measurements for the impact on the patients’ quality of life in respect to diet, pain, gastrointestinal symptoms and daily life. The questionnaire was validated using 149 normal subjects. Chronbach alpha was 0.86. Test retest reliability was evaluated with 72 normal subjects, the correlation coefficient was 0.93. Discriminate validity was determined to be significant using the normal subject questionnaires and 10 questionnaires from subjects with recurrent SBO. Normative and level of impact for each measured domain were established using one standard deviation from the mean in the normal population and clinical relevance. This questionnaire is a valid and reliable instrument to measure the impact of SBO on a patient’s quality of life related to recurrent SBOs; therefore establishing a mechanism to monitor and quantify changes in quality of life over time.

  15. Noninvasive Multidetector Computed Tomography Enterography in Patients with Small-Bowel Crohn's Disease: Is a 40-Second Delay Better than 70 Seconds?

    International Nuclear Information System (INIS)

    Background: Multidetector computed tomography (MDCT) enterography combines neutral enteric contrast with intravenously administered contrast material. The optimal intravenous (IV) contrast material protocol has still not been established. Purpose: To determine the optimal delay time to image patients with small-bowel Crohn's disease during MDCT enterography. Material and Methods: After oral administration of 1350 ml of neutral contrast medium, 26 patients with small-bowel Crohn's disease underwent MDCT enterography; scans were obtained 40 s (enteric phase) and 70 s (parenchymal phase) after IV administration of 100 ml of iodinated contrast material. Three radiologists, blinded to clinical and pathological findings, independently and retrospectively evaluated each scan in two separate reading sessions for the presence or absence of CT features of Crohn's disease activity. The interobserver agreement was evaluated, and the efficacy of each phase in detecting active disease in the terminal ileum for each reader was determined. The gold standard was pathology (n = 13), endoscopy (n = 3), and clinical evaluation (n 10). Results: No statistically significant difference was present between the enteric and the parenchymal phase for each reader in each segment regarding the presence or absence of CT features of Crohn's disease. The interobserver agreement for the presence of five main features of active Crohn's disease in the terminal ileum ranged from poor to excellent. The sensitivity, specificity, negative predictive value, positive predictive value, and accuracy for active Crohn's disease in the terminal ileum ranged from 40 to 90%, 88 to 100%, 70 to 94%, 44 to 100%, and 69 to 96%, respectively. There was no statistical difference between the two phases for each reader. Conclusion: MDCT enterography in patients with suspected active Crohn's disease can be obtained at either 40 s or 70 s after IV contrast material

    Background: Multidetector computed tomography (MDCT) enterography combines neutral enteric contrast with intravenously administered contrast material. The optimal intravenous (IV) contrast material protocol has still not been established. Purpose: To determine the optimal delay time to image patients with small-bowel Crohn's disease during MDCT enterography. Material and Methods: After oral administration of 1350 ml of neutral contrast medium, 26 patients with small-bowel Crohn's disease underwent MDCT enterography; scans were obtained 40 s (enteric phase) and 70 s (parenchymal phase) after IV administration of 100 ml of iodinated contrast material. Three radiologists, blinded to clinical and pathological findings, independently and retrospectively evaluated each scan in two separate reading sessions for the presence or absence of CT features of Crohn's disease activity. The interobserver agreement was evaluated, and the efficacy of each phase in detecting active disease in the terminal ileum for each reader was determined.

El objetivo de nuestro estudio fue evaluar el potencial diagnóstico de la E-TC en la detección de tumores de ID. En nuestra institución se realizaron 600 E-TC desde Enero del 2005 a Mayo del 2008. Un total de 22 pacientes (3,6 %) presentaron hallazgos tomográficos compatibles con tumores de ID, todos confirmados histológicamente. Los tumores encontrados en esta serie fueron; adenocarcinoma (n:4), linfoma (n:3), tumor carcinoide (n:3), tumor estromal gastrointestinal benigno (n:2), pólipos hamartomatosos (n: 2) y compromiso neoplásico secundario (n:8). Esta serie corrobora el valor de la E-TC como técnica de imagen de elección en la detección de tumores de ID, con la posibilidad de etapificación en el mismo procedimiento. Abstract in english Small bowel neoplasms are rare, accounting for approximately 3-6% of all priman/ malignancies of the gastrointestinal tract. MDCT-E is an imaging modality that combines the advantages of enteroclysis and helical CT, allowing the detection of small bowel diseases wherever they are located (intralumin [...] al, intramural, or extramural). The aim of our study was to assess the reliability of MDCT-E in the detection of small bowel neoplasms. In our institution, MDCT-E was used to study 600 patients admitted for suspicion of small bowel diseases, between January2005 and May 2008. A total of 22 (3, 6 %) small bowel neoplasms were identified, all confirmed by histological examination. The neoplasms found in this series were adenocarci-noma (n: 4), lymphoma (n: 3), carcinoid tumor (n: 3), benign GIST (n: 2), benign hamartomatous polyps (n: 2) and secondary small bowel tumors (n: 8). MDCT-E appears to be a reliable method in the detection of small bowel neoplasms, allowing tumor staging tobe determined during the same procedure.

  18. Short bowel syndrome.

    LENUS (Irish Health Repository)

    Donohoe, Claire L

    2012-02-01

    The short bowel syndrome (SBS) is a state of malabsorption following intestinal resection where there is less than 200 cm of intestinal length. The management of short bowel syndrome can be challenging and is best managed by a specialised multidisciplinary team. A good understanding of the pathophysiological consequences of resection of different portions of the small intestine is necessary to anticipate and prevent, where possible, consequences of SBS. Nutrient absorption and fluid and electrolyte management in the initial stages are critical to stabilisation of the patient and to facilitate the process of adaptation. Pharmacological adjuncts to promote adaptation are in the early stages of development. Primary restoration of bowel continuity, if possible, is the principle mode of surgical treatment. Surgical procedures to increase the surface area of the small intestine or improve its function may be of benefit in experienced hands, particularly in the paediatric population. Intestinal transplant is indicated at present for patients who have failed to tolerate long-term parenteral nutrition but with increasing experience, there may be a potentially expanded role for its use in the future.

  19. The Different Volume Effects of Small-Bowel Toxicity During Pelvic Irradiation Between Gynecologic Patients With and Without Abdominal Surgery: A Prospective Study With Computed Tomography-Based Dosimetry

    International Nuclear Information System (INIS)

    Purpose: To evaluate the effect of abdominal surgery on the volume effects of small-bowel toxicity during whole-pelvic irradiation in patients with gynecologic malignancies. Methods and Materials: From May 2003 through November 2006, 80 gynecologic patients without (Group I) or with (Group II) prior abdominal surgery were analyzed. We used a computed tomography (CT) planning system to measure the small-bowel volume and dosimetry. We acquired the range of small-bowel volume in 10% (V10) to 100% (V100) of dose, at 10% intervals. The onset and grade of diarrhea during whole-pelvic irradiation were recorded as small-bowel toxicity up to 39.6 Gy in 22 fractions. Results: The volume effect of Grade 2-3 diarrhea existed from V10 to V100 in Group I patients and from V60 to V100 in Group II patients on univariate analyses. The V40 of Group I and the V100 of Group II achieved most statistical significance. The mean V40 was 281 ± 27 cm3 and 489 ± 34 cm3 (p 3 and 132 ± 19 cm3 (p = 0.003). Multivariate analyses revealed that V40 (p = 0.001) and V100 (p = 0.027) were independent factors for the development of Grade 2-3 diarrhea in Groups I and II, respectively. Conclusions: Gynecologic patients without and with abdominal surgery have different volume effects on small-bowel toxicity during whole-pelvic irradiation. Low-dose volume can be used as a predictive index of Grade 2 or greater diarrhea in patients without abdominal surgery. Full-dose volume is more important than low-dose volume for Grade 2 or greater diarrhea in patients with abdominal surgery

  20. The benefit of small bowel and pelvic bone sparing in excluding common iliac lymph node region from conventional radiation fields in patients with uterine cervical cancer. A dosimetric study

    International Nuclear Information System (INIS)

    The purpose of this study was to compare dose reduction to the small bowel and sacral bone by two-field and four-field techniques when the common iliac lymph node region is excluded from the radiation field in external beam radiotherapy of uterine cervical cancer. Thirteen patients with cervical cancer were entered into the study. Conventional treatment plans based on bony landmarks were made with parallel-opposed two-field technique (C2F) and four-field box technique (C4F). Modified C2F (M2F) and C4F (M4F) plans of excluding the common iliac lymph node region from the conventional radiation fields were created in reference to the bifurcations of pelvic arteries in computed tomography images. For each patient, the dose volume histograms for the small bowel and sacral bone resulting from the C2F, C4F, M2F, and M4F plans were compared. The volumes were obtained at 10 levels of prescribed dose, at increments of 10%, from 5 Gy to 50 Gy. By sparing both small bowel and sacral bone, the M2F and M4F plans were significantly better than the C2F and C4F plans at any dose level (p<0.05), respectively. In addition, the M4F plan was significantly better than the M2F plan in sparing both small bowel at 10-50% of the prescribed dose (p<0.05) and sacral bone at 40-100% of the prescribed dose (p<0.05). The present study suggests that modified treatment planning could be useful for selected patients for reducing small bowel complications and insufficiency fracture after radiotherapy. (author)

    Background Previous prospective studies have found the incidence of intestinal diverticular disease decreased with increasing intakes of dietary fibre, but associations by the fibre source are less well characterised. We assessed these associations in a large UK prospective study of middle-aged women. Methods and findings During 6 (SD 1) years follow-up of 690?075 women without known diverticular disease who had not changed their diet in the last 5?years, 17?325 were admitted to hospital or died with diverticular disease. Dietary fibre intake was assessed using a validated 40-item food questionnaire and remeasured 1?year later in 4265 randomly-selected women. Mean total dietary fibre intake at baseline was 13.8 (SD 5.0) g/day, of which 42% came from cereals, 22% from fruits, 19% from vegetables (not potatoes) and 15% from potatoes. The relative risk (95% CI) for diverticular disease per 5?g/day fibre intake was 0.86 (0.84 to 0.88). There was significant heterogeneity by the four main sources of fibre (p<0.0001), with relative risks, adjusted for each of the other sources of dietary fibre of 0.84 (0.81 to 0.88) per 5?g/day for cereal, 0.81 (0.77 to 0.86) per 5?g/day for fruit, 1.03 (0.93 to 1.14) per 5?g/day for vegetable and 1.04 (1.02 to 1.07) per 1?g/day for potato fibre. Conclusions A higher intake of dietary fibre is associated with a reduced risk of diverticular disease. The associations with diverticular disease appear to vary by fibre source, and the reasons for this variation are unclear. PMID:24385599

    Purpose: Various radiological methods to diagnose small bowel neoplasmas and problems of differential diagnosis specially considerating leiomyomas are discussed. Patients and methods: Two patients with leiomyoma of the ileum underwent enteroclysis, computed tomography of the abdomen, intra-arterial DSA and colour Doppler sonography. Another patient with leiomyosarcoma just underwent CT of the abdomen with CT-guided biopsy. Results: Due to the homogenous density and the smooth surface of the tumors in computed tomography and respectively enteroclysis and the presentation of the tumor vascularisation in the angiography and Colour Doppler sonography in both patients a leiomyoma of the small bowel was diagnosed. Postoperatively this diagnosis was histologically confirmed. The CT-findings of the patient with leiomyosarcoma were not suspicious of a malignant tumor. Conclusion: Radiologically it is not possible to determine the dignity of smooth muscle cell tumors safely. That is the reason why the diagnosis has to be achieved operatively. But the histopathological diagnosis based on the mitotic rate may be difficult. Therefore the after care has to be carried out thoroughly. (orig.) [Deutsch] Ziel: Es werden Diagnosemoeglichkeiten von Duenndarmtumoren und differentialdiagnostische Problemstellungen unter besonderer Beruecksichtigung des Leiomyoms diskutiert. Patienten und Methode: Bei zwei Patienten mit einem Leiomyom des Ileums wurde jeweils ein Enteroklysma nach Sellink, eine CT des Abdomens, eine intraarterielle DSA mit selektiver Darstellung der Art.mesenterica superior und eine farbkodierte Duplexsonographie (FKDS) durchgefuehrt. Bei einem Patienten mit Leiomyosarkom wurde lediglich eine CT des Abdomens mit CT-gesteuerter Biopsie durchgefuehrt. Ergebnisse: Aufgrund der homogenen Dichtewerte und der glatten Begrenzung der Tumoren in der CT bzw. dem Enteroklysma, ergaenzt durch die farbdopplersonographische und angiographische Darstellung der Tumorgefaesse, wurde bei beiden Patienten ein Leiomyom des Duenndarms diagnostiziert. Postoperativ wurden diese Diagnosen histologisch bestaetigt. Bei dem Patienten mit Leiomyosarkom liess die CT allerdings keinen malignen Tumor vermuten. Schlussfolgerung: Eine sichere Dignitaetsbestimmung glatter Muskelzelltumoren ist radiologisch nicht moeglich. Daher muss der Befund operativ geklaert werden. Die histopathologische Zuordnung, bedingt durch die Mitoserate kann allerdings schwierig sein. Eine gewissenhafte Nachsorge muss daher erfolgen. (orig.)

    Full Text Available RACIONAL: O aumento da prevalência de doença diverticular tornou o seu manuseio mais adequado uma questão de debate constante. Especialmente para os casos de diverticulite, progresso considerável tem sido feito em termos de diagnóstico e tratamento. A ressecção cirúrgica do cólon envolvido é a única [...] maneira de erradicar definitivamente essa condição e, portanto, a colectomia laparoscópica eletiva surgiu como uma opção segura e interessante entre as várias formas de tratamento. OBJETIVO: Analisar os resultados das colectomias laparoscópicas esquerdas para a doença diverticular realizadas durante um período de 17 anos em uma única instituição. MÉTODOS: Entre abril de 1990 e maio de 2007, um total de 205 colectomias consecutivas esquerdas laparoscópicas foram revistas retrospectivamente. Os dados obtidos incluíram o pré-operatório, indicações para a operação, os dados cirúrgicos, complicações e seguimento. Análises estatísticas univariada e multivariada foram realizadas em um esforço para identificar os fatores de risco e efeitos adversos na série. RESULTADOS: As indicações foram diverticulite aguda (80%) não-complicada, diverticulite aguda ou crônica complicada (18,05%) e sangramento na doença diverticular (1,95%). A taxa de conversão foi de 5,85% (12 casos). A mediana do tempo operatório foi de 180 minutos (100-420), com internação hospitalar de 7 (5-44) dias. O comprimento médio do espécime ressecado foi 29,12 centímetros. A maioria dos casos (88,3%) teve curso pós-operatório normal, mas complicações ocorreram em 24 (11,7%) pacientes. Em ordem de frequência foram: íleo paralítico (n = 6), coleções pélvica (n = 4), obstruções intestinais (n = 4) e fístulas (n = 2), entre outros. Re-operação foi necessária em oito casos e houve um óbito (0,48%). O seguimento mediano foi de 26,5 (1-156) meses, com resultado satisfatório em 179 (87,32%) dos pacientes. Em 18 (8,78%) casos, os sintomas persistentes de distúrbios funcionais do cólon foram anotados. Houve sete (3,41%), estenoses da anastomose e em dois precisou de re-operação. A taxa de recidiva foi de 1,95% (4 casos). Idade e complicações intra-operatórias foram identificadas como fatores de risco para a conversão. A presença de lesões associadas foi significativamente correlacionada com a persistência de sintomas funcionais do cólon durante o seguimento. CONCLUSÕES: A colectomia laparoscópica esquerda é segura e eficaz em comparação com todas as outras modalidades de tratamento da doença diverticular. Diagnóstico preciso e cuidado nas indicações são essenciais para atingir bons resultados. Abstract in english BACKGROUND: The increased prevalence of diverticular disease has made its most appropriate management a matter of constant debate. Especially for the cases of diverticulitis, considerable progress has been made in terms of diagnosis and management. The surgical resection of the involved colon is the [...] only means of definitely eradicate this condition and so, the elective laparoscopic colectomy has emerged as a safe and interesting choice among the options of treatment. AIM: To analyze the outcomes of the laparoscopic left colectomy for diverticular disease performed over a 17-year period at a single institution. METHODS: Between April 1990 and May 2007, a total of 205 consecutive left laparoscopic colectomies were retrospectively reviewed. Data obtained included the pre-operative work-up, indications for surgery, operative results, complications and follow-up. Univariate and multivariate statistical analyzes were performed in an effort to identity risk factors for adverse outcomes in the series. RESULTS: Indications were for non-complicated acute diverticulitis (80%), acute or chronic complicated diverticulitis (18.05%) and bleeding diverticular disease (1.95%). The conversion rate was 5.85% (12 cases). The median operative time was 180 (100-420) min with a hospital stay of 7 (5-44) days. The mean length of the resected specimen was 29.12 (+8.2) cm. Mos

  15. The Bowel Microbiota and Inflammatory Bowel Diseases

    Full Text Available The human bowel contains a large and biodiverse bacterial community known as the microbiota or microbiome. It seems likely that the microbiota, fractions of the microbiota, or specific species comprising the microbiota provide the antigenic fuel that drives the chronic immune inflammation of the bowel mucosa that is characteristic of Crohn's disease and ulcerative colitis. At least twenty years of microbiological research have been expended on analysis of the composition of the bowel microbiota of inflammatory bowel disease patients in comparison to that of control subjects. Despite extensive speculations about the aetiological role of dysbiosis in inflammatory bowel diseases, knowledge that can be easily translated into effective remedies for patients has not eventuated. The causes of this failure may be due to poorly defined and executed bacteriological studies, as well as the overwhelming complexity of a biome that contains hundreds of bacterial species and trillions of bacterial cells.

  16. Non-perforating small bowel Crohn's disease assessed by MRI enterography: Derivation and histopathological validation of an MR-based activity index

    International Nuclear Information System (INIS)

    Objectives: To develop and validate a qualitative scoring system for enteric Crohn's disease activity using MR enterography (MRE). Methods: MRE was performed in 16 patients (mean age 33, 8 male) undergoing small bowel resection. Mural thickness, T2 signal, contrast enhancement, and perimural oedema were scored qualitatively (0–3) at 44 locations. Transmural histopathological scoring of acute inflammation (AIS) was performed at all locations (score 0–13). MRI parameters best predicting AIS were derived using multivariate analysis. The MRI activity index was applied to 26 Crohn's patients (mean age 32, range 13–69 years, 15 male) and correlated to terminal ileal biopsy scores of acute inflammation (“eAIS” score 1–6). Receiver operator characteristic curves were calculated. Results: Mural thickness (coefficient 1.34 (95% CI 0.36, 2.32)], p = 0.007) and T2 signal (coefficient 0.90 (95% CI ?0.24, 2.04) p = 0.06) best predicted AIS (AIS = 1.79 + 1.34*mural thickness + 0.94*mural T2 score [R-squared 0.52]). There was a significant correlation between the MRI index and eAIS (Kendall's tau = 0.40, 95% CI 0.11–0.64, p = 0.02). The model achieved a sensitivity of 0.81 (95% CI 0.54–0.96), specificity of 0.70 (0.35–0.93) and AUC 0.77 for predicting acute inflammation (eAIS ?2). Conclusions: A simple qualitative MRI Crohn's disease activity score appears predictive against a histopathological standard of reference

    2011-01-01

    Full Text Available Abstract Introduction Percutaneous or endocavitory drainage of a diverticular abscess under radiological guidance often enables one to perform a one-staged resection and anastomosis (without stoma formation instead of a two-staged procedure. It reduces the significant postoperative morbidity and mortality associated with the conventional emergency surgical management. However, radiological guidance is not always available due to limited resources during out-of-hours. Case presentation A 78-year-old Caucasian woman underwent transrectal drainage of a diverticular abscess performed with a pigtail catheter without radiological guidance. Technical details of the procedure are described and alternative options discussed. Conclusion In carefully selected patients, per-rectal drainage using a pigtail catheter can be performed without radiological guidance and the procedure offers a simple and effective way of controlling sepsis.

    Inflammatory bowel diseases (IBD) are diagnoses that can be easily overlooked clinically. The aim of this study was to investigate if CT is able to make a contribution to the identification of previously unsuspected cases of IBD. We retrospectively identified cases in which the possibility of an IBD was raised in CT reports (over a 4-year period), by utilising a keyword search of the radiology database. Cases with a previously known or suspected IBD were rigorously excluded by review of case notes, and endoscopic, radiological, histological and microbiological findings. The CT images of the identified cases were reviewed by a blinded observer to document the extent of bowel wall thickening, the location of lesion(s), and presence of peri-colic fat abnormality, ascites and/or collections. The observer also attempted to corroborate the presence, and to identify the type, of IBD based on the CT appearances alone. Thirty-five cases (out of approximately 19,000 body CTs performed) of clinically unsuspected IBD were identified, of which 27 underwent further investigation. An IBD was confirmed in 48% (13 of 27): Crohn's disease (n=6), ulcerative colitis (n=2), pseudomembranous colitis (n=3) and other (n=2), of which 70% (9 of 13) were correctly typed by the reviewer. Inflammatory bowel disease was not substantiated in the remainder (14 of 27), although 7 of these had other bowel pathologies: diverticular disease (n=4); and carcinoma (n=3). Prospectively determining the presence, and furthermore type, of IBD on CT is challenging largely because of the considerable overlap in the appearances of the individual IBDs and indeed of normality. Nevertheless, CT is able to identify clinically unsuspected cases and radiologists should be alert to this treatable and not infrequently elusive diagnosis. (orig.)

    Aim: Renal calyceal diverticula are usually detected as incidental findings on intravenous pyelograms (IVPs) and rarely manifest any clinical signs or symptoms. However, they can interfere with patient's quality of life in a number of instances causing pain, recurrent urinary tract infections (UTIs), abscess, systemic sepsis and calculus formation. The purpose of this study was to review the clinical indications, procedure technique and clinical outcome in all patients referred to Interventional Radiology for the percutaneous management of renal calyceal diverticula. Materials and methods: A retrospective review of all patients treated with percutaneous balloon dilatation of calyceal diverticular infundibula in the Interventional Radiology Department over a 10-year period was performed. Data collected included clinical details, laboratory indices, IVP and CT findings, procedure details and clinical outcome. Results: A total of three patients were treated over the course of the study period. All patients were young females who presented as a result of recurrent urinary tract infections. The calyceal diverticula were diagnosed incidentally on routine IVPs, with CT eloquently confirming the plain film findings in two cases. Technical procedure success was achieved in all cases, avoiding surgical intervention. Clinical follow-up revealed no further UTIs following dilatation. Conclusion: Fluoroscopic guided percutaneous balloon dilatation of renal calyceal diverticular infundibula following direct diverticular puncture is a safe and well tolerated method to reduce UTI and potentially avoid future stone formation.

Materials and Methods: Data of the patients operated (from birth to 15 years was retrospectively collected over eight years (January 1999 to December 2006. The biodata of children included the following: Indications for operation, type of operations, duration of admission, and outcome of treatment including complications. Patients with Hirschsprung?s disease were excluded from the study because bowel resection forms part of their definitive surgical management. Results : There were 70 patients (38 boys and 32 girls. The age ranged between four hours to 15 years (median, five months. There were 16 (22.9% neonates, 26 (37.1% infants, and 28 (40% grown children.

Complications included wound infection in 47.8% and anastomotic leak in 42.8%. The duration of admission ranged between 4-35 days (median, 15 days. The overall mortality was 17.1% -; which was highest among neonates (56.3%, followed by the infants (26.9% -. Conclusion : Bowel resections are mainly done for intussusception and complications of TIP at our centre. Late presentation, preexisting malnutrition, and nonavailability of parenteral nutrition contributed to unacceptable morbidity and mortality.

    Purpose: To assess the value of small bowel wall vascularity after microbubble contrast agent injection in evaluating the therapeutic effectiveness of specific anti-inflammatory treatment in patients with Crohn's disease. Materials and methods: Fifteen patients (7 male and 8 female; mean age {+-} SD, 40 years {+-} 6) with a biopsy-proven diagnosis of Crohn's disease - Crohn's disease activity index (CDAI) > 150 (n = 12 patients) or <150 (n = 3) - involving the terminal loop of the small bowel (wall thickness >5 mm) were included. In each patient the terminal loop was scanned by contrast-enhanced ultrasound (CEUS) after sulfur hexafluoride-filled microbubble injection before and after 6-month anti-inflammatory treatment. The vascularity of the terminal loop was quantified in gray-scale levels (0-255) by a manually drawn ROI encompassing the thickened bowel wall and it was correlated with CDAI. Result: Before the beginning of the specific treatment all patients revealed diffuse transparietal contrast enhancement after microbubble injection, except for 3 patients who revealed contrast enhancement limited to the submucosa. In 13 patients the slope of the first ascending tract and the area under the enhancement curve were significantly lower after anti-inflammatory treatment (P < 0.05; Wilcoxon test) with a significant correlation with the CDAI score ({rho} = 0.85, P < 0.05). In 2 patients no significant vascularity changes were found even though a mild reduction of CDAI score was identified (from 200 to 150 gray-scale levels). Conclusion: CEUS is a useful method to assess the therapeutic effectiveness of specific medical anti-inflammatory treatment in patients with Crohn's disease.

    Full Text Available Introducción: La enfermedad diverticular del colon es una entidad frecuente, como también la diverticulitis en sus diferentes estadios de evolución. Existe incertidumbre respecto de las opciones terapéuticas que se utilizan en el tratamiento de la peritonitis diverticular de colon izquierdo (PDCI). [...] El objetivo de este estudio es determinar la mejor opción de tratamiento para pacientes con PDCI entre procedimiento de Hart-mann (PH) y resección con anastomosis primaria (RAP), en términos de mortalidad y morbilidad postoperatoria (MPO). Material y Método: Revisión sistemática de la literatura. Se analizaron estudios realizados en adultos con PDCI tratados con PH y RAP, publicados entre 1990 y 2011. Se consultó en las bases de datos TRIPDATABSE, IWO, MEDLINE, SciELO y LILACS, utilizando estrategias de búsqueda con términos MeSH, palabras libres y operadores booleanos. Los estudios seleccionados fueron analizados mediante un escore de calidad metodológica (CM). Se consideraron las variables mortalidad, MPO, estadía hospitalaria, porcentaje de reconstitución de tránsito en pacientes sometidos a PH y CM de los estudios primarios. Resultados: Se analizaron 26 estudios primarios (47 series de pacientes). No se encontraron diferencias significativas respecto de la variable mortalidad (p = 0,0805); pero sí en la variable MPO, reportada de forma incompleta (p = 0,0187). La mediana de la CM de los estudios primarios fue de 11 puntos para las series de PH y de 10 para las de RAP. Conclusión: La evidencia disponible no permite determinar la mejor alternativa terapéutica en términos de mortalidad y MPO en este tipo de pacientes. Se requieren estudios de mejor nivel de evidencia y CM para aclarar esta incertidumbre. Abstract in english Hartmann's procedure and resection with primary anastomosis in diverticular peritonitis Introduction: Colonic diverticulosis, as diverticulitis, is a frequent disease in different stages of evolution. There is uncertainty about treatment options that are used in secondary peritonitis. The aim of thi [...] s study is to determine the best treatment option for patients with peritonitis secondary to diverticulitis of the left colon in terms of postoperative morbidity (POM) and mortality, comparing Hartmann's procedure (HP) and resection with primary anastomosis (RPA). Material and Methods: Systematic review. Studies in adults with peritonitis secondary to diverticulitis of the left colon treated with HP and RPA published between 1990 and 2011 were analyzed. TRIPDATABSE, IWO, MEDLINE, SciELO and LILACS databases were consulted and search strategies were applied using MeSH and free terms. Selected studies were analyzed using a score of methodological quality (MQ). The following variables were considered: mortality, POM, hospital stay, percentage of bowel transit reconstitution in patients undergoing HP and MQ of primary studies. Results: 26 primary studies were analyzed (47 series). There were no significant differences in the variable mortality (p = 0.0805), but significant difference was observed in POM (incompletely reported) (p = 0.0187). The median of MQ of the studies was 11 points for HP series and 10 for RPA series. Conclusion: The available evidence to determine the best treatment option in terms of mortality and POM in this kind of patients is insufficient. Studies with better level evidence and MQ are needed to clarify the uncertain.

    Bowel rotation abnormalities in heterotaxy are common. As more children survive cardiac surgery, the management of gastrointestinal abnormalities has become controversial. To evaluate imaging of malrotation in heterotaxy with surgical correlation and provide an algorithm for management. Imaging reports of heterotaxic children with upper gastrointestinal (UGI) and/or small bowel follow-through (SBFT) were reviewed. Subsequently, fluoroscopic images were re-reviewed in conjunction with CT/MR studies. The original reports and re-reviewed images were compared and correlated with surgical findings. Nineteen of 34 children with heterotaxy underwent UGI, 13/19 also had SBFT. In 15/19 reports, bowel rotation was called abnormal: 11 malrotation, 4 non-rotation, no cases of volvulus. Re-review, including CT (10/19) and MR (2/19), designated 17/19 (90%) as abnormal, 10 malrotation (abnormal bowel arrangement, narrow or uncertain length of mesentery) and 7 non-rotation (small bowel and colon on opposite sides plus low cecum with probable broad mesentery). The most useful CT/MR findings were absence of retroperitoneal duodenum in most abnormal cases and location of bowel, especially cecum. Abnormal orientation of mesenteric vessels suggested malrotation but was not universal. Nine children had elective bowel surgery; non-rotation was found in 4/9 and malrotation was found in 5/9, with discrepancies (non-rotation at surgery, malrotation on imaging) with 4 original interpretations and 1 re-review. We recommend routine, early UGI and SBFT studies once other, urgent clinical concerns have been stabilized, with elective laparoscopic surgery in abnormal or equivocal cases. Cross-sectional imaging, usually obtained for other reasons, can contribute diagnostically. Attempting to assess mesenteric width is important in differentiating non-rotation from malrotation and more accurately identifies appropriate surgical candidates. (orig.)

    Full Text Available Bezoars are concretions of indigestible materials in the gastrointestinal tract. It generally develops in patients with previous gastric surgery or patients with delayed gastric emptying. Cases of periampullary duodenal divericular bezoar are rare. Clinical manifestations by a bezoar vary from no symptom to acute abdominal syndrome depending on the location of the bezoar. Biliary obstruction or acute pancreatitis caused by a bezoar has been rarely reported. Small bowel obstruction by a bezoar is also rare, but it is a complication that requires surgery. This is a case of acute pancreatitis and subsequent duodenal obstruction caused by a large duodenal bezoar migrating from a periampullary diverticulum to the duodenal lumen, which mimicked pancreatic abscess or microperforation on abdominal computerized tomography. The patient underwent surgical removal of the bezoar and recovered completely.

    2014-02-01

    Videocapsule endoscopy (VCE) has revolutionized our ability to visualize the small bowel mucosa. This modality is a valuable tool for the diagnosis of obscure small bowel Crohn's disease (CD), and can also be used for monitoring of disease activity in patients with established small-bowel CD, detection of complications such as obscure bleeding and neoplasms, evaluation of response to anti-inflammatory treatment and postoperative recurrence following small bowel resection. VCE could also be an important tool in the management of patients with unclassified inflammatory bowel disease, potentially resulting in reclassification of these patients as having CD. Reports on postoperative monitoring and evaluation of patients with ileal pouch-anal anastomosis who have developed pouchitis have recenty been published. Monitoring of colonic inflammatory activity in patients with ulcerative colitis using the recently developed colonic capsule has also been reported. Capsule endoscopy is associated with an excellent safety profile. Although retention risk is increased in patients with small bowel CD, this risk can be significanty decreased by a routine utilization of a dissolvable patency capsule preceding the ingestion of the diagnostic capsule. This paper contains an overview of the current and future clinical applications of capsule endoscopy in inflammatory bowel disease. PMID:24574792

    Full Text Available Congenital short bowel syndrome (SBS is a relatively rare condition as compared to acquired SBS. It is associated with significant mortality and morbidity. Infants usually present with failure to thrive, recurrent vomiting, and diarrhea. It is important to suspect and diagnose this condition promptly, as early initiation of parenteral nutrition or surgery, if necessary, may result in a favorable outcome. We discuss a case of an infant aged 26 days, who presented with failure to thrive, recurrent vomiting, and weight loss. A contrast study of the gastrointestinal tract revealed a short small bowel, with malrotation. The infant was started on parenteral nutrition, but succumbed shortly thereafter to severe disseminated sepsis.

    Full Text Available OBJECTIVES: To describe our experience with bowel vaginoplasty done in children. MATERIALS AND METHODS: This is a retrospective study of eight children aged 10 months to 8 years, who underwent bowel vaginoplasty over a period of 5 years (2000-2005. The indications of bowel vaginoplasty included anorectovestibular fistula (ARVF associated with Mayer-Rokitansky-Kuster-Hauser (MRKH syndrome (n=6 and cloaca (n=2. The bowel segment used for vaginoplasty included colon (n=3, ileum (n=2 and duplicated rectum (n=1. In two patients of ARVF associated with uterovaginal agenesis, the distal- most part of ARVF was transected at the level of peritoneal reflection and left as neovagina, whereas the proximal bowel was pulled through at the proposed neo-anal site. All the patients were advised daily home dilatation of the neo vaginal orifice with Hegar?s dilators, for a period of six weeks. RESULTS: Bowel vaginoplasty was done in eight patients. None had any significant per-operative complication. Two patients had abdominal wound dehiscence, requiring secondary suturing. Two patients had mucosal prolapse of the neovagina, which required trimming. One patient died two months after discharge, because of meningitis. Out of the eight patients, seven are in regular follow-up. Six patients have neovagina, cosmetically acceptable to the parents; all have been radiologically proven to have adequate length. One patient had unacceptable perineal appearance with nipple-like vaginal orifice and scarred perineal wound, that merits a revision. None of the patients had vaginal stenosis and excessive mucus discharge, during follow-up visits. Although post surgical results are acceptable to the parents cosmetically, the sexual and psychological outcome is yet to be assessed. Conclusions: Bowel vaginoplasty is a safe and acceptable procedure to treat the pediatric patients of uterovaginal agenesis and cloaca.

    Full Text Available Background: Elective surgery in diverticular disease (DD consists classically in performing an open sigmoidectomy. Laparoscopic surgery of the colon can have results that are comparable to those of open surgery. Aim: To compare the results of laparoscopic and conventional surgery for DD. Materials and Methods: Retrospective review of preoperative, operative and postoperative variables of patients operated by laparoscopic surgery between the years 2000 and 2002. These results were compared with those of patients treated with conventional surgery in the same period. Results: Thirty nine patients, mean age 59 years old, were operated via laparotomy and 18 patients, mean age 47 years old, were treated with laparoscopic surgery. Both groups were comparable in gender, amount of previous laparotomies, type of surgery performed and American Society of Anestesiologists classification. The operative time was significantly higher in the laparoscopic surgery group (230 v/s 130 min, but the opioid requirements, stay in an intensive surgical care ward, postoperative ileus and hospital stay were significantly shorter in the laparoscopic group. Eleven percent of the patients included in the laparoscopic group and 31% of the patients treated with operative surgery had complications (p=0.07. The length of the excised colon, the degree of inflammation and treatment costs were comparable. Conclusions: Laparoscopic surgery in DD is feasible, safe, requires less analgesia and allows a faster recovery of post-operative ileus and a lower hospital stay (Rev Méd Chile 2003; 131: 719-26

  15. The diagnostic value of small bowel wall vascularity after sulfur hexafluoride-filled microbubble injection in patients with Crohn's disease. Correlation with the therapeutic effectiveness of specific anti-inflammatory treatment

    International Nuclear Information System (INIS)

    Purpose: To assess the value of small bowel wall vascularity after microbubble contrast agent injection in evaluating the therapeutic effectiveness of specific anti-inflammatory treatment in patients with Crohn's disease. Materials and methods: Fifteen patients (7 male and 8 female; mean age ± SD, 40 years ± 6) with a biopsy-proven diagnosis of Crohn's disease - Crohn's disease activity index (CDAI) > 150 (n = 12 patients) or 5 mm) were included. In each patient the terminal loop was scanned by contrast-enhanced ultrasound (CEUS) after sulfur hexafluoride-filled microbubble injection before and after 6-month anti-inflammatory treatment. The vascularity of the terminal loop was quantified in gray-scale levels (0-255) by a manually drawn ROI encompassing the thickened bowel wall and it was correlated with CDAI. Result: Before the beginning of the specific treatment all patients revealed diffuse transparietal contrast enhancement after microbubble injection, except for 3 patients who revealed contrast enhancement limited to the submucosa. In 13 patients the slope of the first ascending tract and the area under the enhancement curve were significantly lower after anti-inflammatory treatment (P < 0.05; Wilcoxon test) with a significant correlation with the CDAI score (? = 0.85, P < 0.05). In 2 patients no significant vascularity changes were found even though a mild reduction of CDAI score was identified (from 200 to 150 gray-scale levels).

    Full Text Available A forma de avaliar e lidar com a hemorragia aguda digestiva baixa tem sido modificado com os recentes desenvolvimentos de novas técnicas e aparelhos. O nosso objetivo, por esse manuscrito, é demonstrar com simplicidade uma forma de condução dos pacientes com hemorragia digestiva baixa aguda, sobretudo para os sangramentos que parecem mais graves, principalmente quando nos faltam os recursos das avançadas tecnologias atuais. Doenças localizadas no intestino grosso respondem por ¼ dos casos de hemorragias digestivas que são motivos para admissão hospitalar e têm como principais agentes etiológicos os divertículos, na moléstia diverticular, e as alterações vasculares, nas angiodisplasias. Na grande maioria das vezes o sangramento que pode parecer abundante cessa espontaneamente. Os distúrbios circulatórios graves não são comuns e os sinais mais frequentes são a queda do valor da hemoglobina observada na metade dos pacientes, e algumas alterações hemodinâmicas como a variação pressórica postural que pode ser vista em até 30% dos casos; a síncope em 10% e alguma forma de colapso circulatório, em 9%. Contudo, a faixa etária em que ocorre, as condições da senilidade, as doenças eventualmente associadas e a falta de recursos materiais e humanos para lidar com esse tipo de problema são os motivos que mais causam preocupação. A abordagem clínica simples com uma história bem elaborada; o exame físico com atenção e objetividade, a inclusão do exame proctológico, a obrigatória disponibilidade de aparelho para a coloscopia e os conhecimentos básicos sobre o evento formam o conjunto necessário e, na maioria das vezes, suficiente para o correto desempenho profissional na elaboração dos cuidados que devem ser dados a esses pacientes.The evaluation and management of the acute lower digestive hemorrhage has been modified with the recent development of new techniques and devices. The aim of this manuscript was to demonstrate with simplicity how to treat the patients with acute lower intestinal hemorrhage. Diseases of the large bowel account for the ¼ of the cases of digestive hemorrhages on the hospital admission and have as main etiological agents the diverticula, in the diverticular disease, and small vascular malformation, in the angiodysplasias. Sometime, it can be seen as a life-threatening condition, however, most of the times, the hemorrhage stops spontaneously. The serious circulatory disturbances are not common; the most frequent signs are the decrease in hemoglobin occurring on about one half of patients and some form of circulatory disturbance as orthostatic changes in 30%; as syncope in 10% and as cardiovascular collapse in 9%. However, the age group, the conditions of the senility, the eventually associated diseases and the lack of material and human resources to handle with that kind of problem are the reasons for concern. The simple clinical approach with a well elaborated history; the physical examination released with attention and objectivity, the inclusion of the proctologic exam, the obligatory readiness for an endoscope for colonoscopy, the basic knowledge on the event are necessary and, in most of the times, enough for the good professional acting in the elaboration of the cares that it should be given to those patient ones.

    Full Text Available We herein report the rare complication of sepsis caused by endoscopic clipping for colonic diverticular bleeding. A 78-year-old man with a 12-h history of near syncope and painless hematochezia was admitted to our hospital. Following the transfusion of 4 U of blood and continued hematochezia, a colonoscopy was performed. Active bleeding was seen as continuous arterial spurting from a single diverticulum located in the middle ascending colon. This diverticulum was seamed by four endoclips. The next day, the patient became febrile with a temperature of 39.2°C. Laboratory data included a white blood cell count of 18 100/mm3 and a C-reactive protein level of 3.4 mg/dL. He was diagnosed with sepsis since Escherichia coli was detected in the blood culture. Antibiotics were started. Four days later his fever had improved and laboratory data improved 9 d later.

  18. Usefulness of multidetector computed tomography in the diagnosis of lower gastrointestinal diverticular hemorrhage

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the diagnostic ability of Multidetector Computed Tomography (MDCT) for lower gastrointestinal diverticular hemorrhage. Three radiologists reviewed MDCT findings in 12 cases and investigated the relationship between imaging findings and the patients' blood pressure, volume of transfusion, and treatments applied. MDCT examination demonstrated ''extravasation'' in 7 cases, and luminal abnormalities, id est (i.e.), ''high density area with bubble'', ''fluid collection'' and ''clot'' in 5, 8, and 4 cases, respectively. Four of six cases who required blood transfusion demonstrated extravasation. The systolic blood pressure of three cases with extravasation was below 95 mmHg. Extravasation on MDCT which was frequently observed in patients with hypotension and/or requiring blood transfusion, was highly specific for diagnosing the bleeding site. MDCT was also useful for procedural planning in IVR, endoscopic and surgical management. (author)

    Full Text Available AIM: To investigate in symptomatic uncomplicated diverticular disease the efficacy of symbiotics associated with a high-fibre diet on abdominal symptoms. METHODS: This study was a multicentre, 6-mo randomized, controlled, parallel-group intervention with a preceding 4-wk washout period. Consecutive outpatients with symptomatic uncomplicated diverticular disease, aged 40-80 years, evaluated in 4 Gastroenterology Units, were enrolled. Symptomatic uncomplicated diverticular disease patients were randomized to two treatment arms A or B. Treatment A (n = 24 patients received 1 symbiotic sachet Flortec© (Lactobacillus paracasei B21060 once daily plus high-fibre diet for 6 mo. Treatment B (n = 21 patients received high-fibre diet alone for 6 mo. The primary endpoint was regression of abdominal symptoms and change of symptom severity after 3 and 6 mo of treatment. RESULTS: In group A, the proportion of patients with abdominal pain < 24 h decreased from 100% at baseline to 35% and 25% after 3 and 6 mo, respectively (P < 0.001. In group B the proportion of patients with this symptom decreased from 90.5% at baseline to 61.9% and 38.1% after 3 and 6 mo, respectively (P = 0.001. Symptom improvement became statistically significant at 3 and 6 mo in group A and B, respectively. The proportion of patients with abdominal pain >24 h decreased from 60% to 20% then 5% after 3 and 6 mo, respectively in group A (P < 0.001 and from 33.3% to 9.5% at both 3 and 6 mo in group B (P = 0.03. In group A the proportion of patients with abdominal bloating significantly decreased from 95% to 60% after 3 mo, and remained stable (65% at 6-mo follow-up (P = 0.005 while in group B, no significant changes in abdominal bloating was observed (P = 0.11. After 6 mo of treatment, the mean visual analogic scale (VAS values of both short-lasting abdominal pain (VAS, mean ± SD, group A: 4.6 ± 2.1 vs 2.2 ± 0.8, P = 0.02; group B: 4.6 ± 2.9 vs 2.0 ± 1.9, P = 0.03 and abdominal bloating (VAS, mean ± SD, group A: 5.3 ± 2.2 vs 3.0 ± 1.7, P = 0.005; group B: 5.3 ± 3.2 vs 2.3 ± 1.9, P = 0.006 decreased in both groups, whilst the VAS values of prolonged abdominal pain decreased in the Flortec© group, but remained unchanged in the high-fibre diet group (VAS, mean ± SD, group A: 6.5 ± 1.5 vs 4.5 ± 2.1, P = 0.052; group B: 4.5 ± 3.8 vs 5.5 ± 3.5. CONCLUSION: A high-fibre diet is effective in relieving abdominal symptoms in symptomatic uncomplicated diverticular disease. This treatment may be implemented by combining the high-fibre diet with Flortec©.

  20. Post double-contrast sigmoid flush: An adjuvant technique in imaging diverticular disease

    International Nuclear Information System (INIS)

    In a prospective study, the effect of a low-density contrast medium infusion was evaluated as an adjunct to high-density double-contrast medium sigmoid imaging. Following a double-contrast medium barium enema (DCBE), 52 consecutive patients with sigmoid diverticulosis received an additional 500-700-mL enema with either water or a 1.5%CT barium suspension. Rectosigmoid films were evaluated for luminal distention, visualization of the interhaustral space, definition of diverticula, and interpretation of polypoid defects. While double-contrast medium views were excellent in 21%, improvement in multiple factors by water or 1.5% barium flush resulted in improved sigmoid images in 65% and 73% of patients, respectively. Polyps may be confirmed and artifactual defects confidently excluded. Sigmoid flush, particularly with low-density barium, is a simple adjunct to DCBE that improves visualization of the diverticular sigmoid

  1. Is “pelvic radiation disease” always the cause of bowel symptoms following prostate cancer intensity-modulated radiotherapy?

    International Nuclear Information System (INIS)

    Background: Pelvic radiation disease (PRD) also widely known as “radiation proctopathy” is a well recognised late side-effect following conventional prostate radiotherapy. However, endoscopic evaluation and/or specialist referral for new or persistent post-prostate radiotherapy bowel symptoms is not routine and serious diagnoses may potentially be missed. Here we report a policy of endoscopic evaluation of bowel symptoms persisting >90 days post radiotherapy for prostate cancer. Methods and materials: A consecutive series of 102 patients who had radical prostate intensity-modulated radiotherapy (IMRT)/image-guided radiotherapy (IGRT) and who had new or ongoing bowel symptoms or positive faecal occult blood tests (FOBT) on follow up visits more than three months after treatment, were referred for endoscopic examination. All but one (99%) had full colonoscopic investigation. Results: Endoscopic findings included gastric/colonic/rectal polyps (56%), diverticular disease (49%), haemorrhoids (38%), radiation proctopathy (29%), gastritis/oesophagitis (8%) and rarer diagnoses, including bowel cancer which was found in 3%. Only four patients (4%) had radiation proctopathy without associated pathology and 65 patients (63%) had more than one diagnosis. If flexible sigmoidoscopy alone were used, 36.6% of patients and 46.6% patients with polyp(s) would have had their diagnoses missed. Conclusions: Our study has shown that bowel symptoms following prostate IMRT/IGRT are due to numerous diagnoses other than PRD, including malignancy. Routine referral pathways should be developed for endoscopic evaluation/specialist review for patients with new or persistent bowel symptoms (or positive FOBT) following prostate radiotherapy. This recommendation should be considered for incorporation into national guidelines

    Full Text Available Em estudo recente demonstramos que a infusão de células da medula óssea do doador após o transplante intestinal não aumentou a sobrevida do enxerto quando se utilizou series curtas de drogas imunossupressoras. OBJETIVO: Neste estudo avaliamos se a utilização de diferentes regimes de irradiação em as [...] sociação com a infusão de medula óssea altera a sobrevida do enxerto e a morbidade sobre receptor. MÉTODOS: Realizou-se o transplante heterotópico de intestino delgado, utilizando-se ratos Lewis como receptores e DA como doadores, imunossuprimidos com FK 506 na dose de 1mg/kg/dia por 5 dias e distribuídos em 4 grupos: G1 (n= 4), não irradiado e sem infusão de medula óssea; G2 (n= 6), G3 (n= 9) e G4 (n= 6) foram infundidos com 100 x 10(6) células de medula após o transplante. Grupos 3 e 4 foram irradiados com 250 e 400 rd respectivamente. Os animais foram examinados diariamente para a detecção de rejeição e reação do enxerto versus hospedeiro, tendo sido colhidas amostras semanais de sangue para estudos de quimerismose biopsias quinzenais da estomia. RESULTADOS: Animais nos G1 e G2 apresentaram rejeição mínima no 15º pós-operatório, enquanto a reação do enxerto versus hospedeiro foi caracterizada nos G3 e G4. Os níveis de quimerismo total e de células T foram maiores nos grupos irradiados em comparação aos não irradiados. A causa mortis nos G1 e G2 foi a rejeição enquanto que nos G3 e G4 foi a reação do enxerto versus hospedeiro. CONCLUSÃO: Concluímos que a utilização de baixas doses de irradiações retardam o aparecimento da rejeição, mas não previne a ocorrência da reação do enxerto versus hospedeiro. Abstract in english In our previous work we demonstrated that the use of donor specific bone marrow infusions ( DSBMI ) after small bowel transplantation did not improve the graft survival after a short course of immunossupression. PURPOSE: In the current study, we evaluated whether recipient preconditioning with diffe [...] rent regimens of radiation combined with DSBMI may enhance small bowel allograft survival with minimum recipient morbidity. METHODS: Heterotopic small bowel transplantation (SBTx) was performed with Lewis rats as recipients and DA rats as donors, which were immunossupressed with a short course of tacrolimus (FK 506 ) at 1mg/Kg/day for 5 days and distributed in 4 groups: group 1 (n= 4) without both irradiation and DSBMI; Groups 2 (n= 6), 3 (n= 9) and 4 (n= 6) received 100 x 10(6) DSBM cells at the time of the transplant. Groups 3 and 4 were irradiated with 250 and 400 rd respectively. Animals were examined daily for clinical signs of rejection or GVHD. Blood samples were taken weekly for chimeric studies by FC and intestinal biopsies were performed every 2 weeks. RESULTS: Animals in G1 and G2 had minimal rejection at day 15 after SBTx while GVHD was clinically and histologically characterized in G 3 and G 4. Total chimerism and T-cell chimerism was higher in irradiated groups when compared to non-irradiated groups. With exception of G1 and 2 where rejection was the cause of death, all animals in G3 and 4 died of GVHD. CONCLUSION:We concluded that low cytoreductive of irradiation can successfully decrease the graft rejection but not prevent the occurrence of GVHD.

    Optimal management of chronic idiopathic inflammatory bowel disease requires determination of disease localization and intensity. Scintigraphy with the use of {sup 99m}Tc - HMPAO- White Bloods Cells ({sup 99m}Tc - HMPAO-WBC) is a relatively new noninvasive nuclear medicine procedure. They have evaluated more than 230 children and have found a high correspondence between the disease distribution shown by the {sup 99m}Tc - HMPAO- WBC scan and that shown by endoscopic, radiologic, or surgical methods. Additionally the {sup 99m}Tc - HMPAO-WBC scan has the ability of identifying extra intestinal site of inflammation, such as appendicitis and others. The {sup 99m}Tc - HMPAO-WBC scan is reliable in differentiating Crohn`s disease from ulcerative colitis. Some patients because of unequivocal demonstrable small bowel uptake are reclassified from ulcerative colitis to Crohn`s disease. The medication regimen is frequently altered because of the intensity of uptake displayed by the {sup 99m}Tc - HMPAO-WBC scan. It is a practical and safe study even in an acutely ill patient who may not tolerate endoscopic or radiological study. At their institution, the {sup 99m}Tc - HMPAO-WBC scan is now part of the initial evaluation, and follow-up of patients with inflammatory bowel disease. In conclusion the {sup 99m}Tc - HMPAO-WBC is excellent for the detection, localization and characterization of inflammatory bowel disease in children. Compared with the other methods of investigation this study requires no bowel preparation, is noninvasive and has excellent diagnostic accuracy.

    Full Text Available Abstract Background Adhesive small intestine occlusion [ASIO] is an important cause of hospital admission placing a substantial burden on healthcare systems worldwide. Often times, ASIO is associated with significant morbidity and mortality. Icodextrin 4% solution [Adept, Shire Pharmaceuticals, UK] is a high-molecular-weight a-1,4 glucose polymer that is approved in Europe for use as an intra-operative lavage and a post-operative instillate to reduce the occurrence of post-surgery intra-abdominal adhesions. There are no randomized trials on the use of this solution to prevent adhesions after ASIO operation in current medical literature. The current clinical study evaluates the safety and effectiveness of Icodextrin 4% for decreasing the incidence, extent, and severity of adhesions in patients after abdominal surgery for ASIO. Design The study project is a prospective, randomized controlled investigation performed in the Department of Transplant, General and Emergency Surgery of St. Orsola-Malpighi University Hospital [Bologna, Italy]. The study is designed and conducted in compliance with the principles of Good Clinical Practice regulations. The study compares the results of Icodextrin 4% against a control group who does not receive anti-adhesion treatment. This randomized study uses a double-blind procedure to evaluate efficacy end points. In other words, designated third party individuals who are unaware of the treatment assigned to the patients to assess adhesion formation.

    Full Text Available OBJECTIVE: To review recent evidence on dietary factors associated with diverticular disease (DD with special emphasis on dietary fibre. QUALITY OF EVIDENCE: MEDLINE was searched from January 1966 to December 2001 for articles on the relationship between dietary and other lifestyle factors and DD. Most articles either focused on dietary intervention in treating symptomatic DD or were case-control studies with inherent limitations for studying diet-disease associations. Only one large prospective study of male health professionals in the United States assessed diet at baseline and before initial diagnosis of DD. MAIN MESSAGE: A diet high in fibre mainly from fruits and vegetables and low in total fat and red meat decreases risk of DD. Evidence indicates that the insoluble component of fibre is strongly associated with lower risk of DD; this association was particularly strong for cellulose. Caffeine and alcohol do not substantially increase risk of DD, nor does obesity, but higher levels of physical activity seem to reduce risk of DD. CONCLUSION: A diet high in fibre and low in total fat and red meat and a lifestyle with more physical activity might help prevent DD.

MÉTODOS: 32 ratos machos foram submetidos a clampeamento da artéria e da veia mesentéricas superiores durante 60 minutos (isquemia) seguido de 60 minutos de reperfusão. A [...] pós estes procedimentos os animais fora separados em quatro grupos, a saber: grupo I (GI) isquemia e reperfusão (IR); grupo II (GII) submetido a OHB concomitante a isquemia, Grupo III (GIII) submetido a OHB durante a reperfusão e, grupo IV (GIV) submetido a OHB durante o período de isquemia e de reperfusão. A OHB foi realizada em câmara acrílica (2.0 ATA). Após anestesia, fragmentos do intestino delgado (íleo) foram fixados e processados para inclusão em parafina sendo os cortes corados pelo HE. As lâminas foram avaliadas quanto a presença de lesões histopatológicas da mucosa e avaliado a espessura da mucosa. RESULTADOS: A lesão histopatológica da mucosa foi significativamente inferior quando a OHB foi administrada na isquemia (12.6 ± 0.6) em comparação com o IR (21.3 ± 1.8). A OHB não foi efetiva quando aplicada durante a reperfusão (23.1 ± 2.1), ou durante a isquemia e reperfusão (18.7 ± 1.9). A espessura da mucosa foi preservada pela OHB na isquemia (327,50 ± 30.23 µm) em comparação com o IR (172.79 ± 5.95 µm). Nos períodos de reperfusão (162.50 ± 6.05 µm) e a isquemia (296.49 ± 20.01 µm) a mucosa apresentou lesão estrutural. CONCLUSÃO: A oxigenação hiperbárica protege a mucosa intestinal quando realizada durante o período de isquemia. Abstract in english PURPOSE: To determine whether hyperbaric oxygen (HBO) could effectively protect the small intestine mucosa against an ischemic insult, according to different periods of application. METHODS: The gut of 32 male rats was subjected to 60-min ischemia (clamping the mesenteric artery and vein); After the [...] y were further reperfused upon clamp opening during 60 min. Animal groups were as follows. GII = placed on HBO during the ischemia period; GIII = placed on HBO during reperfusion; GIV = treated with HBO throughout the ischemia-reperfusion period. Some animals (GI) did not receive HBO treatment at all and served as reference of ischemia-reperfusion injury (IR). HBO was carried out in a cylindrical acrylic chamber (2.0 ATA). Samples of small bowel were prepared for H.E staining for histological evaluations. RESULTS: The histological injury of mucosa was significantly less when HBO was administered during the ischemia period (17.6 ± 0.6) as compared with the IR (21.3 ± 1.8). HBO was not effective when applied during reperfusion (23.1 ± 2.1) or during the ischemia plus reperfusion period (18.7 ± 1.9). The thickness of the mucosa was preserved by HBO in ischemia (327.50 ± 30.23 µm) in comparison with the IR (172.79 ± 5.95 µm). In the periods of reperfusion (162.50 ± 6.05 µm) and ischemia plus reperfusion (296.49 ± 20.01 µm) the mucosa revealed a structural injury. CONCLUSION: Hyperbaric oxygen affects the ischemic insult of small bowel, being the favorable effect obtained when hyperbaric oxygen was administered early in the ischemic period.

  16. Role of indium-111 white blood cells in inflammatory bowel disease

    International Nuclear Information System (INIS)

    Inflammatory bowel disease in patients may be difficult to diagnose because of the complex problems associated with this disease. Radionuclides are able to provide a rapid and effective method of imaging the bowel in patients with active inflammatory bowel disease. In the past, clinical work-ups have included barium x-ray studies and endoscopy. Scarring and fistula formation have made it difficult to determine between the active disease and abscesses that may occur. Gallium-67 (67Ga) has been very useful in imaging patients with inflammatory bowel disease, but the multiple-day imaging procedure has been a limitation for the clinicians when achieving a diagnosis. Recent results with Indium-111 (111In)--labeled WBCs have provided excellent correlation between clinical symptoms and colonoscopy findings in patients with inflammatory bowel disease. This technique has also allowed the differentiation between reoccurring inflammatory bowel disease and abscesses that accompany the disease within a 24-hour time period. The use of intravenous (IV) glucagon has increased the clarity of the images in the small bowel. Technetium 99m (99mTc) diethylenetriaminepentaacetic acid (DTPA) has been used in patients with inflammatory bowel disease demonstrating promising results. Investigators feel labelling 99mTc with WBCs will be improved, therefore yielding a greater efficiency, which will have a major impact on imaging patients with inflammatory bowel disease. Imaging patients with inflammatory bowel disease using radionuclides has yielded promising results. This is a significant advancement over barium radiography and endoscopy exams.24 references

    Twenty-five patients with functional bowel disease were given fructose, sorbitol, fructose-sorbitol mixtures, and sucrose. The occurrence of malabsorption was evaluated by means of hydrogen breath tests and the gastrointestinal symptoms, if any, were recorded. One patient could not be evaluated because of lack of H2 production. Based on a cut-off level of 10 ppm rise of H2 concentration, malabsorption was apparent in 13 patients, in 7 of which the calculated absorption capacities were below 15 g...

  18. Altered gastric emptying in patients with irritable bowel syndrome

    International Nuclear Information System (INIS)

    Irritable bowel syndrome is the most frequent functional disorder of the digestive system. Patients with irritable bowel syndrome have motor disorders not only in the colon, but also in other parts of the digestive tract such as the oesophagus and small intestine; however, it is not known whether the stomach is also involved. We used a radiolabelled mixed solid-liquid meal (technetium-99m for the solid component, indium-111 for the liquid component) to study gastric emptying of solids (GES), liquids (GEL) and indigestible solids (GER) in 50 patients diagnosed as having irritable bowel syndrome (30 with predominant constipation and 20 with predominant diarrhoea). GER was measured by counting the number of indigestible solids remaining in the stomach 4 h after they were swallowed. In patients with irritable bowel syndrome, GES and GEL were slower than in control subjects (P<0.05). GER was normal in all patients except for two women. Thirty-two patients (64%) showed delayed GES, 29 (58%) delayed GEL, and 2 (4%) delayed GER. Among patients with irritable bowel syndrome, GES was slower in those with predominant constipation than in those with predominant diarrhoea (P<0.05); GEL and GER were similar in both groups. Gastroparesis was found in a large proportion of patients with irritable bowel syndrome, suggesting the presence of a more generalised motor disorder of the gut. (orig.)

  1. Coexisting Liver Disease Is Associated with Increased Mortality After Surgery for Diverticular Disease

    DEFF Research Database (Denmark)

    Montomoli, Jonathan; Erichsen, Rune

    2015-01-01

    BACKGROUND: Coexistence of liver disease in patients undergoing surgery for diverticular disease (DD) may increase the risk of postoperative complications, but the evidence is limited. AIM: To investigate the impact of liver disease on mortality and reoperation rates following surgery for DD. METHODS: We performed a cohort study based on medical databases of all patients undergoing surgery for DD in Denmark during 1977-2011, categorizing them into three cohorts according to history of liver disease: patients with non-cirrhotic liver disease, those with liver cirrhosis, and those without liver disease (comparison cohort). Using the Kaplan-Meier method, we computed mortality in each cohort for 0-30, 31-60, and 61-90 days following surgery for DD. We used a Cox regression model to compute hazard ratios as measures of the relative risk (RR) of death, controlling for potential confounders, including other comorbidities. In addition, we assessed the reoperation rate within 30 days of initial surgery. RESULTS: Of14,408 patients undergoing surgery for DD, 233 (1.6 %) had non-cirrhotic liver disease and 91 (0.6 %) had liver cirrhosis. Thirty-day mortality was 9.9 % in patients without liver disease and 14.6 % in patients with non-cirrhotic liver disease [adjusted RR = 1.64 (95 % confidence interval [CI] 1.16-2.31)]. Among patients with liver cirrhosis, mortality was 24.2 % [adjusted RR = 2.70 (95 % CI 1.73-4.22)]. Liver cirrhosis had an impact on mortality up to 60 days after surgery for DD. The reoperation rate was approximately 10 % in each cohort. CONCLUSION: Preexisting liver disease has a major impact on postoperative mortality following surgery for DD.

    Aim: To evaluate the predictors of clinically important gastrointestinal anastomotic leaks using multidetector computed tomography (CT). Subjects and methods: Ninety-nine patients, 73 with clinical suspicion of anastomotic bowel leak and 26 non-bowel surgery controls underwent CT to investigate postoperative sepsis. Fifty patients had undergone large bowel and 23 small bowel anastomoses. The time interval from surgery was 3-30 days (mean 10 {+-} 5.9 SD) for the anastomotic group and 3-40 days (mean 14 {+-} 11 SD) for the control group (p = 0.3). Two radiologists blinded to the final results reviewed the CT examinations in consensus and recorded the presence of peri-anastomotic air, fluid or combination of the two; distant loculated fluid or combination of fluid and air; free air or fluid; and intestinal contrast leak. Final diagnosis of clinically important anastomotic leak (CIAL) was confirmed at surgery or by chart review of predetermined clinical and laboratory criteria. Results: The prevalence of CIAL in the group undergoing CT was 31.5% (23/73). The CT examinations with documented leak were performed 5-28 (mean; 11.4 {+-} 6 SD) days after surgery. Nine patients required repeat operation, 10 percutaneous abscess drainage, two percutaneous drainage followed by surgery, and two prolonged antibiotic treatment and total parenteral nutrition (TPN). Of the CT features examined, only peri-anastomotic loculated fluid containing air was more frequently seen in the CIAL group as opposed to the no leak group (p = 0.04). There was no intestinal contrast leakage in this cohort. Free air was present up to 9 days and loculated air up to 26 days without CIAL. Conclusion: Most postoperative CT features overlap between patients with and without CIAL. The only feature seen statistically more frequently with CIAL is peri-anastomotic loculated fluid containing air.

Material and methods: this prospective study carried out from January 1999 to December 2001, included 100 patients with clinical and radiological criteria of adhesive SBO. We described the past medical history, as well as clinical picture, blood tests and radiological findings in these patients. Fifty cubic centimeters of 5% barium suspension were given orally, and plain abdominal radiographs were taken at 4, 8, 16, and 24 hours afterwards. A liquid diet was given as soon as the contrast medium appeared in the right colon. Otherwise, surgical intervention was considered based on the outcome of the patient and the criteria of the emergency surgical team. Results: in 70 patients, barium contrast appeared in the right colon, and a liquid diet was tolerated by 69 of them (98.6%). Mean hospitalization time for this group was 43 ± 17 hours. In the remaining 30 patients, no evidence of barium contrast in the right colon was seen, and 25 of them underwent surgery (75%), while the other 5 tolerated a liquid diet. Mean hospitalization time for this second group of patients was 13.8 ± 11 days. Sensitivity, specificity, positive predictive value, and negative predictive value for the absence of contrast medium in the right colon within 24 hours as a predictor of surgery were 93, 96, 98 and 83%, respectively.

    Introduction The colostomy is often necessary in complicated divertcular disease. The laparoscopic colostomy is not widely used for the treatment of complicated diverticular disease. Its use in patients with high operative risk is still on debate. The aim of this case report was to present the benefits of laparoscopic colostomy in patients with high peri-and postoperative risk factors. Presentation of case We present a case of 76-year-old female admitted to emergency unit for left colonic obstruction. The patient had a past history of liver cirrhosis HCV-related with a severe malnutrition, hypertrophic cardiomyopathy, diverticular disease, hiatal ernia, previous appendectomy. Patient was classified according to their preoperative risk ASA 3 (classification of the American society of Anestesia-ASA score). Contrast-enhanced abdominal CT revealed a marked thickening in the sigmoid colon and a marked circumferential stenosis in the sigmoid colon in absence of neoplasm, and/or abscess. The laparoscopic procedure is proposed as first intention. Discussion The operation time was 50 min, and the hospital stay was 4 days. Post operative complications grade I according to the Clavien Dindo Classification. Conclusions Laparoscopic colostomy is safe and feasible procedure in experienced hands. It is associated with low morbidity and short stay in hospital and should be considered a good alternative to a laparotomy. PMID:26036456

    Full Text Available Crohn’s disease and ulcerative colitis affect women in their child-bearing years. Family planning has come to be a common discussion between the gastroenterologist and the inflammatory bowel disease (IBD patient. Disease control prior to desired conception and throughout pregnancy is the most important thing to keep in mind when caring for the IBD patient. Continued medical management during pregnancy is crucial in optimizing outcomes. Studies indicate that quiescent disease prior to conception infer the best pregnancy outcomes, similar to those in the general population. Active disease prior to and during pregnancy, can lead to complications such as pre-term labor, low birth weight, and small for gestational age infants. Although there are no definitive long term effects of pregnancy on IBD, there are some limited studies that suggest that it may alter the disease course. Understanding the literature and its limitations is important in the modern era of IBD care. Educating the patient and taking a team approach with the obstetrician will help achieve successful outcomes for mother and baby.

  7. CT findings of bowel and mesenteric injury

    International Nuclear Information System (INIS)

    To evaluate the role of CT in the diagnosis of bowel and mesenteric injury we studied the CT findings and its usefulness in patients of abdominal trauma. CT scans of 27 patients who were confirmed to have bowel and/or mesenteric injury due to abdominal trauma were analyzed retrospectively. Of these 27 patients 15 had bowel injury only and 12 had both bowel and mesenteric injury. CT findings analysed were bowel wall thickening, presence or absence of highly attenuated bowel wall, sentinel clot, mesenteric infiltration, peritoneal fluid collection and free intraabdominal air in cases with bowel injury only and with both bowel and mesenteric injury respectively. Ten patients had other accompanying abdominal injuries, such as liver, spleen, pancreas, kidney, bladder injuries, intraperitoneal abscess or retroperitoneal hemorrhage. Findings observed were bowel wall thickening in 23 cases (85%), peritoneal fluid collection in 21 (78%), highly attenuated bowel wall in 19 (70%), mesenteric infiltration in 17 (63%), free intraperitoneal air in 10 (37%) and sentinel clot in 7 (26%). Pneumoperioneum were observed in 10 of 24 patients (41,7%) having bowel perforation. Two cases did not show any CT findings suggesting bowel and/or mesenteric injury. There was no significant difference in the prevalence of the CT findings between the patient group with bowel injury only and the patient group with both bowel and meseneric injury. CT scan is a useful tool in evaluating the degree and extent of bowel and/or mesenteric injury as well as in planning the patient's management

  15. Value of “protruding lips” sign in malignant bowel obstructions

    International Nuclear Information System (INIS)

    Objective: This study aims to evaluate the diagnostic accuracy of a new CT sign in order to define or exclude a malignant aetiology of bowel obstruction. Materials and methods: CT scans of 137 patients affected by bowel obstruction were reviewed. Colonic obstruction occurred in 47 (34%) cases, small bowel obstruction in 90 (66%). Neoplastic aetiology was found in 42 cases (31%), while in the remaining 95 (69%) obstruction was caused by non-neoplastic conditions. Definitive diagnosis was surgically confirmed in all patients. CT images were evaluated searching for bowel obstruction's signs and for the presence of the “protruding lips” sign on the proximal surface of stenosis, which is represented by the evidence of a protrusion within the dilated loop. Results: The sign was found in 31 (23%) cases, all of neoplastic origin. When malignant obstruction was diagnosed, sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy values of the described sign were 74%, 100%, 100%, 90% and 92%, respectively. Conclusions: The “protruding lips” sign represents an alteration to be searched when bowel obstruction is diagnosed by CT examination. Its evidence correlates to a malignant condition with a 100% probability and when it is not found, the probability of a non-neoplastic condition is 90%.

    In this review, we provide an update on genome-wide association studies (GWAS) in inflammatory bowel disease (IBD). In addition, we summarize progress in defining the functional consequences of associated alleles for coding and noncoding genetic variation. In the small minority of loci where major association signals correspond to nonsynonymous variation, we summarize studies defining their functional effects and implications for therapeutic targeting. Importantly, the large majority of GWAS-associated loci involve noncoding variation, many of which modulate levels of gene expression. Recent expression quantitative trait loci (eQTL) studies have established that the expression of most human genes is regulated by noncoding genetic variations. Significant advances in defining the epigenetic landscape have demonstrated that IBD GWAS signals are highly enriched within cell-specific active enhancer marks. Studies in European ancestry populations have dominated the landscape of IBD genetics studies, but increasingly, studies in Asian and African-American populations are being reported. Common variation accounts for only a modest fraction of the predicted heritability and the role of rare genetic variation of higher effects (ie, odds ratios markedly deviating from 1) is increasingly being identified through sequencing efforts. These sequencing studies have been particularly productive in more severe very early onset cases. A major challenge in IBD genetics will be harnessing the vast array of genetic discovery for clinical utility through emerging precision medical initiatives. In this article, we discuss the rapidly evolving area of direct-to-consumer genetic testing and the current utility of clinical exome sequencing, especially in very early onset, severe IBD cases. We summarize recent progress in the pharmacogenetics of IBD with respect to partitioning patient responses to anti-TNF and thiopurine therapies. Highly collaborative studies across research centers and across subspecialties and disciplines will be required to fully realize the promise of genetic discovery in IBD. PMID:26255561

Caso clínico: Varón de 70 años de edad con antecedentes de colocación de endoprótesis biliar plástica tras presentar coledocolitiasis posterior a colecistectomía, que acudió al Servicio de Urgencias con clínica de obstrucción intestinal. Después de realizar radiología simple y ecografía abdominal, se observó importante dilatación intestinal y una endoprótesis biliar en sigma. Se practicó intervención quirúrgica urgente, hallándose endoprótesis biliar plástica enclavada en un divertículo sigmoideo. Se realizó extracción de la endoprótesis y sutura simple de la perforación diverticular sigmoidea. Conclusión: La perforación diverticular sigmoidea secundaria a la migración de una endoprótesis biliar plástica es una complicación poco frecuente que puede aparecer tras la colocación de una endoprótesis en la vía biliar. Dicha perforación debe sospecharse ante todo cuadro de abdomen agudo que se acompaña de imágenes radiológicas que demuestren la migración de la endoprótesis biliar, ya que estos pacientes no suelen presentar una sintomatología típica.

Endoscopic placement of biliary stents is a well established procedure that is performe [...] d daily. Despite its frequency, has a complication rate of 5-10%, the most common are cholangitis and stent obstruction and there are others more rare and serious like pancreatitis, gastrointestinal bleeding, intestinal perforation and biliary stent migration. Case report: We report a 70-years-old male with a history of plastic biliary stent placement after open cholecystectomy because of choledocholithiasis, who arrived at the Emergency Department with symptoms of intestinal obstruction. After performing imaging studies, there was significant intestinal dilation and a biliary stent in the sigmoid colon. He underwent urgent surgical intervention, having the plastic biliary stent located in a sigmoid diverticulum. We performed removal of the stent and simple suture of the sigmoid diverticular perforation. Conclusion: Sigmoid diverticular perforation secondary to migration of a plastic biliary stent is a rare complication that can occur after placement of a stent in the bile duct. It must be suspected in all acute abdomens accompanied of radiological images demonstrating biliary stent migration because these patients often show atypical symptoms.

    Chronic inflammatory bowel disease is diagnosed and monitored by the combination of colonoscopy and small bowel enteroklysis. Magnetic resonance imaging has become the gold standard for the imaging of perirectal and pelvic fistulas. With the advent of ultrafast MRI small and large bowel imaging has become highly attractive and is being advocated more and more in the diagnostic work up of inflammatory bowel disease. Imaging protocols include fast T{sub 1}-weighted gradient echo and T{sub 2}-weighted TSE sequences and oral or rectal bowel distension. Furthermore, dedicated imaging protocols are based on breath-hold imaging under pharmacological bowel paralysis and gastrointestinal MR contrast agents (Hydro-MRI). High diagnostic accuracy can be achieved in Crohn's disease with special reference to the pattern of disease, depth of inflammation, mesenteric reaction, sinus tract depiction and formation of abscess. In ulcerative colitis, the mucosa-related inflammation causes significantly less bowel wall thickening compared to Crohn's disease. Therefore with MRI, the extent of inflammatory changes is always underestimated compared to colonoscopy. According to our experience in more than 200 patients as well as the results in other centers, Hydro-MRI possesses the potential to replace enteroklysis in the diagnosis of chronic inflammatory bowel disease and most of the follow-up colonoscopies in Crohn's disease. Further technical improvements in 3D imaging will allow interactive postprocessing of the MR data. (orig.) [German] Zusammenfassung: Die Standardverfahren in der Diagnostik und der Verlaufskontrolle chronisch entzuendlicher Darmerkrankungen, speziell des Morbus Crohn und der Colitis ulcerosa, sind die Koloskopie und das Enteroklysma. Die MRT hat sich dazu ihren festen Platz in der Diagnostik perirektaler Fisteln erobert. Mit schnellen, T{sub 1}-gewichteten Gradienten-Echo-Sequenzen und T{sub 2}-gewichteten Turbo-Spin-Echo-Sequenzen koennen auch Duenn- und Dickdarm nach oraler oder rektaler Fuellung zuverlaessig dargestellt werden. Die Hydro-MRT als spezielles MR-Untersuchungsprotokoll mit Bildakquisition in Atemstillstand unter medikamentoeser Darmhypotonie und Verwendung intestinaler MR-Kontrastmittel erlaubt die Abbildung intestinaler und extraintestinaler pathologischer Veraenderungen beim M. Crohn. Hierzu rechnen einerseits entzuendliche Darmwandverdickung und Stenosen, andererseits Fisteln, entzuendliche Konglomerate und Abszesse. Bei der Colitis ulcerosa ist im Gegensatz zum Morbus Crohn in der Hydro-MRT eine deutlich geringere entzuendliche Wandverdickung typisch. Ferner ist bei der Colitis ulcerosa die Ausdehnung der Befunde in der MRT regelmaessig geringer als in der Endoskopie. Die Hydro-MRT kann nach unseren eigenen Erfahrungen an mehr als 200 Patienten und den Ergebnissen anderer Zentren das Enteroklysma in der Diagnostik chronisch entzuendlicher Darmerkrankungen und die Mehrzahl von Wiederholungsendoskopien beim Morbus Crohn ersetzen. Weiterentwicklungen der Technik erlauben interaktive multiplanare Nachverarbeitungen der MR-Datensaetze. (orig.)

    Full Text Available Estudos realizados há mais de 10 anos demonstraram que a deficiência ontogenética de lactase é freqüente na população brasileira. Entretanto, esses estudos se basearam no incremento da glicemia após sobrecarga de doses não utilizadas habitualmente na dieta. Atualmente, aceita-se que a avaliação da a [...] bsorção da lactose com o teste do hidrogênio no ar expirado é mais apropriada que o teste da curva glicêmica. Por outro lado, a enteropatia ambiental sintomática e/ou assintomática constituem um grave problema de saúde pública em grupos populacionais de baixo nível sócio-econômico de nosso meio. A ocorrência de sobrecrescimento bacteriano no intestino delgado de crianças com enteropatia ambiental, foi caracterizada em crianças moradoras em favelas. Sobrecrescimento bacteriano no intestino delgado é caracterizado pela presença de bactérias pertencentes à flora colônica no intestino delgado. Objetivando avaliar a freqüência de má absorção de lactose e determinar a ocorrência de sobrecrescimento bacteriano no intestino delgado em crianças escolares, através do teste do H2 no ar expirado, investigaram-se 83 alunos de uma escola localizada na região periférica da cidade de Marília, Estado de São Paulo, após sobrecarga oral de lactose e lactulose. Foram colhidas também amostras de fezes para pesquisa de parasitas. Má absorção de lactose foi observada em 19 (22,9%) escolares e intolerância à lactose em 10 (12,0%). Sobrecrescimento bacteriano no intestino delgado foi identificado pelo teste do H2 no ar expirado em 6 (7,2%) dos 83 escolares. Giardia lamblia foi o parasita mais freqüentemente isolado nas fezes dos escolares. A ocorrência de deficiência ontogenética de lactase observada neste grupo de crianças foi semelhante ao relatado para populações caucasianas. Sobrecrescimento bacteriano foi encontrado neste grupo de crianças assintomáticas, podendo refletir as condições desfavoráveis de seu meio ambiente. Abstract in english The aim of this study was to determine the lactose absorption capacity and possible existence of bacterial overgrowth in the small bowel in asymptomatic school children of low social economic level in Marilia, a city located in the interior of São Paulo state. Eighty three children aging 7 to 15 yea [...] rs old without any gastrointestinal manifestations at least 30 days prior to the tests were studied. All the patients had fasted for at least 8 hours before the tests were performed. Lactose absorption was evaluated by breath hidrogen test after an overload of lactose 18 g in 10% aquous solution. Lactose intolerance was determined by the occurrence of clinical symptoms, such as diarrhea, abdominal pain, flatulence, etc in the following 24 hours after the test was performed. Bacterial overgrowth was evaluated by the breath hidrogen test after a 10 g lactulose load in aqueous solution. Lactose malabsorption was detected in 19 (22.9%) children and lactose intolerance was observed in 10 (12%) children. Lactose intolerance was more frequently observed in children who showed lactose malabsorption (6/19; 31.6%) than in those who presented a normal test (4/64; 6.3%) (P = 0.008). Bacterial overgrowth was detected in six (7.2%) children and showed no statistical relationship with lactose malabsorption. Ontogenetic lactose malabsorption verified in this group of school children is similar to the reported for Caucasian populations. Presence of bacterial overgrowth confirms the existence of asymptomatic environmental enteropathy in children of low social economic level.

    Full Text Available RACIONAL: A oclusão temporária da veia porta causa estase esplâncnica e pode causar dismotilidade intestinal. OBJETIVO: Avaliar as alterações da atividade mioelétrica e da histologia do intestino delgado, além da pressão arterial média (PAM), frequência cardíaca (FC), pressão venosa central (PVC) e [...] pressão portal (PP), na fase de pré-oclusão e de oclusão portal. MÉTODO: Realizou-se anestesia geral em seis cães, seguido de monitorização da PAM, FC e PVC, laparotomia, aferição da PP, fixação de três pares de eletrodos na parede intestinal, biópsias jejunais e oclusão parcial da veia porta, sendo programado aumento da PP entre 2,5 e 3 vezes. Os eletrodos foram conectados a um microcomputador com software de aquisição para armazenamento e análise da atividade mioelétrica, cujo registro ocorreu nos 30 minutos da fase de pré-oclusão e nos 60 minutos de oclusão. Determinouse a variância e a média do RMS (root mean square) da atividade mioelétrica. RESULTADOS: Na fase de oclusão, houve diminuição significativa da média do RMS e aumento da frequência de hemorragia da lâmina própria, sendo proporcional ao tempo de estase.Infiltrado inflamatório, dilatação vascular e desprendimento epitelial não apresentaram diferença entre as duas fases. Durante a estase, PAM, FC e PVC diminuíram (p=0,326; 0,375 e 0,008; respectivamente), e PP aumentou (p=0,015). CONCLUSÃO: A oclusão parcial da veia porta de cães promoveu diminuição da atividade mioelétrica e aumento da frequência percentual da hemorragia da lâmina própria, além de queda da PVC Abstract in english BACKGROUND: Temporary occlusion of the portal vein causes splancnic venous stasis and intestinal disfunction, that can produce alterations in the motility, and this fact is not vastly known. AIM: To evaluate the small bowel myoelectric activity and histology in the six dogs, also covering mean arter [...] ial blood pressure (AP), pulse rate (PR), central venous pressure (CVP) e portal pressure (PP), in two phases: pre-occlusion and occlusion. METHODS: It was done general anesthesia, invasive monitorization of the AP, PR e CVP, laparotomy, measure of the PP, fixation of the three pairs of electrodes in the intestinal wall, jejunal biopsy and parcial occlusion of the portal vein, being programmed the increase of the PP between 2.5 and 3 times baseline. Electrodes were connected to a computer system that captured electrical signals from the intestine. The computer has a software of acquisition to store and analyse the myoelectric activity after registering, what happened in 30 minutes of the pre-occlusion phase and in 60 minutes of occlusion. The variance and the mean RMS(root mean square) of the myoeletric activity were determined. The statistical analysis was done with Friedman, Dunn, Cochran and Students t tests. RESULTS: Mean RMS of myoeletric activity showed significant decrease in the phase of portal occlusion, in comparison to preocclusion phase. The frequency of hemorrhage of the lamina propria was major during occlusion. It was proportional at stasis time, with significant difference between the preocclusion and the occlusion of 60 minutes. Inflammatory infiltration, vascular dilation and epithelial detachment did not show any differences between two phases. During the stasis, AP, PR and CVP decreased (p=0,326; 0,375 e 0,008, respectively), and PP increased(p=0,015). CONCLUSIONS: Parcial occlusion of the portal vein produced reduction of the myoeletric activity and elevation of the percentage frequency of hemorrhage in lamina propria, and a fall of CVP, with relative hemodynamic stabilization.

From the group with no statistical significantly expression, 12 genes were up-regulated and 8 genes were down-regulated. Surprisingly, 37 (44.04%) showed a higher than threefold up-regulation and then arbitrarily the values was considered as a very significant. Thus, 37 genes (44.04%) were expressed very significantly up-regulated. The remained 47 (55.9%) genes were up-regulated less than three folds (35 genes - 41.6%) or down-regulated less than three folds (12 genes - 14.3%). CONCLUSION: The intestinal ischemia and reperfusion promote a global hyper-expression profile of six different clusters genes related to antioxidant defense and oxidative stress.

  5. Computed tomography of the whole bowel in patients suspected of Crohn's disease. Preliminary report - assessment of examination technique and image quality

    International Nuclear Information System (INIS)

    Evaluation of the usefulness of new technique - computed tomography (CT) of the whole bowel in patients with Crohn's disease and correlation of obtained images with other modalities (MR of the bowel, enteroclysis, barium enema, colonoscopy) and operation results. CT examination was performed in 20 patients suspected of having Crohn's disease, which was confirmed in 16 cases. CT was performed after filling small bowel with fluid administered by catheter placed in duodenum (in 10 patients) or orally (in 10 patients), distension of large bowel with air and intravenous injection of contrast material. Distension of small bowel was assessed in both groups by two radiologists. In 7 patients immediately after CT examination MR of the bowel was performed with contrast enhanced T1-weighted images. Distension of small bowel was better in patients examined after administration of fluid directly to duodenum, although the difference was not statistically significant. In 16 CT studies performed in patients with confirmed Crohn's disease all narrowed bowel segments (n = 25) were diagnosed and extraintestinal abnormalities were visualized (thickening of the mesenteries, enlarged lymph nodes, perirectal changes, abscess, fistula). In 7 patients examined by MR 2 of 10 narrowing (20%) were not diagnosed. CT of the whole bowel is promising method in diagnosis of patients with Crohn's disease. The best views of the small
