    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.

  9. CT enteroclysis in small bowel Crohn's disease

    International Nuclear Information System (INIS)

    The diagnostic evaluation of small bowel Crohn's disease has changed dramatically over the last decade. The introduction of wireless capsule endoscopy, double balloon endoscopy and the introduction of newer therapeutic agents have changed the role of imaging in the small bowel. Additionally, advances in multidetector CT technology have further changed how radiologic investigations are utilized in the diagnosis and management of small bowel Crohn's disease. This article describes how we perform CT enteroclysis in the investigation of small bowel Crohn's disease and discusses the role of CT enteroclysis in the current management of small bowel Crohn's disease.

  12. 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.

  14. 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.)

  16. Disturbances in small bowel motility.

    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.

    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.

  20. 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.

    Full Text Available Bezoars are foreign bodies impacted in the digestive tract resulting of their ingestion and accumulation, involving mainly the stomach,small bowel. Phytobezoars are a rare cause of acute small bowel obstruction. It should be suspected in patients with an increased risk of bezoar formation, such as in the presence of previous gastric surgery and a history suggestive of increased fiber intake. The aim of this work was to identify the diagnostic difficulties and treatment of this rare entity.

    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.

  6. 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

    International Nuclear Information System (INIS)

    The normal small bowel fold is easily seen on conventional studies of the small intestine, but visualization of the small bowel villus is just at the resolution of current roentgenographic technique. When the villi are enlarged, they can be seen radiographically as an irregularity or micronodularity of the small bowel fold. The anatomy of the fold and the pathophysiology of diseases producing fold nodularity (tumor, inflammatory disease, NLH, mastocytosis) and micronodularity (lymphangiectasia, Waldenstrom macroglobulinemia, Whipple disease) are presented, with an emphasis on radiologic-pathologic correlation. The radiologist should suggest certain diseases or conditions based on the roentgenographic characteristics of the closely analyzed small bowel fold

  14. The prevention of radiation-induced small bowel complications

    International Nuclear Information System (INIS)

    Moderate dose pelvic radiotherapy is associated with a 5% severe complication risk related to the small bowel. Strictures and/or fistulation can occur many years after treatment. These complications are difficult to treat, and surgical treatment (excision, bypass) bears a significant morbidity risk. The risk of chronic diarrhoea or malabsorption may increase to 40%, depending on the irradiated small bowel volume. Late small bowel complications are generally irreversible due to vascular aetiology. Prevention of these complications can be achieved by limiting the volume of small bowel treated. Consequence for radiotherapeutic techniques in treatment for rectal cancer are multiple beam set-up, customised blocking based on visualisation of the small bowel in the treatment position, and the use of a special open table-top device that results in a small bowel shift from the treatment field.

    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

  16. Small bowel obstruction due to phytobezoar: CT diagnosis

    International Nuclear Information System (INIS)

    Small bowel phytobezoars are rare and are almost always obstructive. The literature contains few reports on the radiological findings for primary small bowel bezoars. There is also very little published on CT results with this lesion, but the features of the scan are characteristic. We present the CT findings in a patient with an obstructive small bowel phytobezoar, and emphasize the diagnostic value of CT. (orig.)

    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.

    Immunoglobulin G4 (IgG4)-related sclerosing disease is rare and is known to involve various organs. We present a case of histologically proven IgG4-related sclerosing disease of the small bowel with imaging findings on computed tomography (CT) and small bowel series. 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.

    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.

    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.)

  3. Gastric, small bowel, and colorectal cancer

    International Nuclear Information System (INIS)

    The majority of gastrointestinal (GI) tract malignancies are adenocarcinomas. In the colon, adenocarcinoma is practically the only clinically significant tumor, and it is the second most common tumor in the small bowel, with carcinoid being the most common. The stomach harbors the greatest variety of malignant neoplasms. Adenocarcinoma, however, is still the predominant cell type, followed by lymphoma and leiomyosarcoma. Various diagnostic procedures have been used to screen patients for GI tract tumors. Fiberoptic endoscopic examination has been advocated as the study of choice to screen the population at risk of developing stomach and colon cancer because of its ability to directly visualize the mucosa and to permit biopsy of suspicious lesions. However, because fiberoptic endoscopy requires patient sedation, the number of endoscopists is limited, and the number of patients is large, single-contrast and double-contrast roentgenographic examinations of the GI tract remain the most widely accepted screening procedures

    Video capsule endoscopy (VCE) has expanded the range of endoscopic examination of the small bowel. The clinical application of VCE is mainly for obscure gastrointestinal bleeding (OGIB) and small bowel tumor is one of the clinically significant diagnoses of VCE, often requiring subsequent invasive interventions. Small bowel tumors are detected with a frequency of around 4% with VCE in indications of OGIB, iron deficiency anemia, unexplained abdominal pain, and others. Protruding mass with bleeding, mucosal disruption, irregular surface, discolored area, and white villi are suggested as the VCE findings of small bowel tumor. Device assisted enteroscopy (DAE), computed tomography enteroclysis/enterography and magnetic resonance enteroclysis/enterography also have clinical value in small bowel examination and tumor detection, and they can be used with VCE, sequentially or complementarily. Familial adenomatous polyposis, Peutz-Jeghers syndrome, melanoma, lymphoma, and neuroendocrine tumor with hepatic metastasis are the high risk groups for small bowel tumors, and surveillance programs for small bowel tumors are needed. VCE and radiological imaging have value in screening, and in selected cases, DAE can provide more accurate diagnosis and endoscopic treatment. This review describes the usefulness and clinical impact of VCE on small bowel tumors. PMID:26855919

  6. 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.

    In functional constipation, three pathophysiological subgroups have been identified: slow-transit constipation (STC); normal-transit constipation (NTC) and outlet delay (OD). Extracolonic manifestations, especially disturbed small bowel motility, are well known to occur in STC, but have rarely been studied in NTC and OD. To perform 24-h-ambulatory jejunal manometry in a large prospective series of clinical patients with chronic constipation of all subtypes. A total of 61 consecutive patients, referred to our tertiary gastroenterologic centre for chronic constipation (48 female, 13 male; mean age 57 (range 20-87) years), underwent jejunal 24-h-ambulatory manometry (standardized meal) after a transit-time study (radio-opaque markers), anorectal manometry, defecography and colonoscopy. Computerized and visual analysis by two independent observers was compared with the normal range of manometric variables, defined by data previously obtained in 50 healthy subjects (Gut 1996;38:859). Five patients were excluded from the study because of coexistence of OD and STC. No patient with OD (n = 8), but all patients with STC (n = 32) and 94% of patients with NTC (n = 16) showed small bowel motor abnormalities; both in postprandial response and fasting motility. The abnormal findings ranged from severe disturbances with complete loss of MMC to subtle changes of contraction parameters that could only be assessed by computerized analysis. No significant differences between STC- and NTC-patients were found. Most findings pointed to an underlying enteric neuropathy. Intestinal prolonged-ambulatory manometry adds valuable information to the pathophysiologic understanding of functional chronic constipation of STC- and NTC-type, however there are no distinct manometric features to differentiate between both.

    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.)

    2015-09-01

    Bleeding from the small intestine remains a relatively uncommon event, accounting for ~5-10% of all patients presenting with gastrointestinal (GI) bleeding. Given advances in small bowel imaging with video capsule endoscopy (VCE), deep enteroscopy, and radiographic imaging, the cause of bleeding in the small bowel can now be identified in most patients. The term small bowel bleeding is therefore proposed as a replacement for the previous classification of obscure GI bleeding (OGIB). We recommend that the term OGIB should be reserved for patients in whom a source of bleeding cannot be identified anywhere in the GI tract. A source of small bowel bleeding should be considered in patients with GI bleeding after performance of a normal upper and lower endoscopic examination. Second-look examinations using upper endoscopy, push enteroscopy, and/or colonoscopy can be performed if indicated before small bowel evaluation. VCE should be considered a first-line procedure for small bowel investigation. Any method of deep enteroscopy can be used when endoscopic evaluation and therapy are required. VCE should be performed before deep enteroscopy if there is no contraindication. Computed tomographic enterography should be performed in patients with suspected obstruction before VCE or after negative VCE examinations. When there is acute overt hemorrhage in the unstable patient, angiography should be performed emergently. In patients with occult hemorrhage or stable patients with active overt bleeding, multiphasic computed tomography should be performed after VCE or CTE to identify the source of bleeding and to guide further management. If a source of bleeding is identified in the small bowel that is associated with significant ongoing anemia and/or active bleeding, the patient should be managed with endoscopic therapy. Conservative management is recommended for patients without a source found after small bowel investigation, whereas repeat diagnostic investigations are recommended for patients with initial negative small bowel evaluations and ongoing overt or occult bleeding.

    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

  13. 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.

    The diagnosis of bowel pathology is challenging in view of the nonspecific clinical presentation. Currently, there are various imaging modalities available to reach an accurate diagnosis. These modalities include conventional techniques (radiographs, small bowel follow-through, conventional enteroclysis), ultrasonography, and cross-sectional examinations (computed tomography [CT] and MR imaging) as well as functional imaging modalities, such as PET-CT or PET-MR imaging. Each modality has its own advantages and disadvantages and can be used in isolation or combination. This review discusses the role of CT, MR imaging, and PET-CT in the evaluation of small and large bowel diseases. PMID:26590441

The number of previous laparotomies, thin physique, and hypertension were significantly associated with complications. Two patients receiving isoniazid and 2 receiving Premarin had enteric complications. Pre-existing vascular damage may potentiate radiation damage to the small bowel.

    Background Small bowel angiodysplasias (SBA) account for 50% of obscure gastrointestinal bleeding. Lesions bleed recurrently and current treatments are relatively ineffective at reducing re-bleeding. Little is known about the natural history of SBA which is needed to guide treatment decisions and counsel patients on prognosis. Aim The aim of this study is to describe the natural history of a cohort of patients with SBA. Methods Patients with SBA were identified retrospectively and clinical and outcome information were collected. Logistic regression analysis was performed to identify factors associated with re-bleeding. Results SBAs were found in 86 patients of which 54% (n?=?47) were female, and the average age was 71.6 years. The majority (69%) had multiple lesions, mean of 2.76/patient, and 65% were located in the jejunum. Follow-up was available in 65% (n?=?56). There was a significant increase in haemoglobin level from 10.05g/dL to 11.94g/dL, p?events occurred in 80% (n?=?45), with an average of 2.91/person. The mean interval between diagnosis and the first re-bleeding event was 10.7 months. Of the group overall, 70% (n?=?40) required transfusions during follow up, and 67% required hospitalisation due to re-bleeding. About 50% received a directed treatment, including argon plasma coagulation, somatostatin analogues, or surgical resection. A total of 3.5% (n?=?2) died as a direct consequence of bleeding from SBAs. Multiple lesions (p?=?0.048) and valvular heart disease (p?=?0.034) were predictive of re-bleeding. Conclusion Our results show the significant impact of SBA on patients' morbidity, with high rates of re-bleeding, persistent anaemia and a mortality rate of 3.5%, despite the use of currently available medical and endoscopic therapies.

    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.

    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.

  1. US features of transient small bowel intussusception in pediatric patients

    International Nuclear Information System (INIS)

    To describe the sonographic (US) and clinical features of spontaneously reduced small bowel intussusception, and to discuss the management options for small bowel intussusception based on US findings with clinical correlation. During a five years of period, 34 small bowel intussusceptions were diagnosed on US in 32 infants and children. The clinical presentations and imaging findings of the patients were reviewed. The clinical presentations included abdominal pain or irritability (n = 25), vomiting (n 5), diarrhea (n = 3), bloody stool (n = 1), and abdominal distension (n = 1), in combination or alone. US showed multi-layered round masses of small (mean, 1.5 ± 0.3 cm) diameters and with thin (mean, 3.5 ± 1 mm) outer rims along the course of the small bowel. The mean length was 1.8 ± 0.5 cm and peristalsis was seen on the video records. There were no visible lead points. The vascular flow signal appeared on color Doppler images in all 21 patients examined. Spontaneous reduction was confirmed by combinations of US (n = 28), small bowel series (n = 6), CT scan (n = 3), and surgical exploration (n 2). All patients discharged with improved condition. Typical US findings of the transient small bowel intussusception included 1) small size without wall swelling, 2) short segment, 3) preserved wall motion, and 4) absence of the lead point. Conservative management with US monitoring rather than an immediate operation is recommended for those patient with typical transient small bowel intussusceptions. Atypical US findings or clinical deterioration of the patient with persistent intussusception warrant surgical exploration

    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

  3. Whirl sign as CT finding in small-bowel volvulus

    International Nuclear Information System (INIS)

    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.)

    Abdominal cocoon is a rare condition that results in an intestinal obstruction due to total or partial encapsulation of the small bowel by a fibrocollagenous membrane. Treatment is surgical resection of the membrane and free the bowel. Preoperative diagnosis is possible with combination of sonography and CT scan. We report two cases where the diagnosis of abdominal cocoon was suggested preoperatively based on the sonography and CT scan of abdomen. PMID:21643736

    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.

    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.

  11. Normal tissue tolerance to external beam radiation therapy: Small bowel

    International Nuclear Information System (INIS)

    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 cm3) but also 30 and 50 Gy (thresholds of 35 to 300 cm3, 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)

    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.

  18. 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

    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.

    2013-01-01

    Full Text Available AIM: To evaluate small bowel cleansing quality, diagnostic yield and transit time, comparing three cleansing protocols prior to capsule endoscopy. METHODS: Sixty patients were prospectively enrolled and randomized to one of the following cleansing protocols: patients in Group A underwent a 24 h liquid diet and overnight fasting; patients in Group B followed protocol A and subsequently were administered 2 L of polyethylene glycol (PEG the evening before the procedure; patients in Group C followed protocol B and were additionally administered 100 mg of simethicone 30 min prior to capsule ingestion. Small bowel cleansing was independently assessed by two experienced endoscopists and classified as poor, fair, good or excellent according to the proportion of small bowel mucosa under perfect conditions for visualization. When there was no agreement between the two endoscopists, the images were reviewed and discussed until a consensus was reached. The preparation was considered acceptable if > 50% or adequate if > 75% of the mucosa was in perfect cleansing condition. The amount of bubbles was assessed independently and it was considered significant if it prevented a correct interpretation of the images. Positive endoscopic findings, gastric emptying time (GET and small bowel transit time (SBTT were recorded for each examination. RESULTS: There was a trend favoring Group B in achieving an acceptable (including fair, good or excellent level of cleansing (Group A: 65%; Group B: 83.3%; Group C: 68.4% [P = not significant (NS] and favoring Group C in attaining an excellent level of cleansing (Group A: 10%; Group B: 16.7%; Group C: 21.1% (P = NS.

Conversely, 7 patients (35% in Group A, 3 patients (16.7% in Group B and 6 patients (31.6% in Group C were considered to have poor small bowel cleansing (P = 0.417, with significant fluid or debris such that the examination was unreliable. The proportion of patients with a significant amount of bubbles was 50% in Group A, 27.8% in Group B and 15.8% in Group C (P = 0.065. This was significantly lower in Group C when compared to Group A (P = 0.026. The mean GET was 27.8 min for Group A, 27.2 min for Group B and 40.7 min for Group C (P = 0.381. The mean SBTT was 256.4 min for Group A, 256.1 min for Group B and 258.1 min for Group C (P = 0.998. Regarding to the rate of complete examinations, the capsule reached the cecum in 20 patients (100% in Group A, 16 patients (88.9% in Group B and 17 patients (89.5% in Group C (P = 0.312. A definite diagnosis based on relevant small bowel endoscopic lesions was established in 60% of the patients in Group A (12 patients, 44.4% in Group B (8 patients and 57.8% in Group C (11 patients (P = 0.587. CONCLUSION: Preparation with 2 L of PEG before small bowel capsule endoscopy (SBCE may improve small bowel cleansing and the quality of visualization. Simethicone may further reduce intraluminal bubbles. No significant differences were found regarding GET, SBTT and the proportion of complete exploration or diagnostic yield among the three different cleansing protocols.

    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.

    Full Text Available Abstract Background Preoperative radiotherapy of the pelvic abdomen presents with complications mostly affecting the small bowel. The aim of this study was to define the features of early radiation-induced injury on small bowel. Methods 54 mice were divided into two groups (36 irradiated and 18 sham irradiated. Animals were placed on a special frame and (in the radiated group the exteriorized segment of ileum was subjected to a single absorbed dose of 19 or 38 Gy radiation using 6 MV high energy photons. Specimens were collected for histology, immunohistochemistry (IHC and ELISA analysis after 2, 24 and 48 hours. Venous blood was collected for systemic leucocyte count in a Burker chamber. Results Histology demonstrated progressive infiltration of inflammatory cells with cryptitis and increased apoptosis. MIP-2 (macrophage inflammatory protein concentration was significantly increased in irradiated animals up to 48 hours. No significant differences were observed in IL-10 (interleukin and TNF-? (tumour necrosis factor levels. IHC with CD45 showed a significant increase at 2 hours of infiltrating leucocytes and lymphocytes after irradiation followed by progressive decrease with time. Caspase-3 expression increased significantly in a dose dependent trend in both irradiated groups up to 48 hours. Conclusion Acute small bowel injury caused by local irradiation is characterised by increased apoptosis of crypt epithelial cells and by lymphocyte infiltration of the underlying tissue. The severity of histological changes tends to be dose dependent and may affect the course of tissue damage.

    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

    This study aimed to evaluate the feasibility and effectiveness of closing the small bowel in an ex vivo porcine model with high-frequency welding device. A total of 100 porcine small bowels were divided into two groups, and then were closed with two different methods. The fifty small bowels in experimental group were closed by the high-frequency welding device, and the other fifty small bowels in comparison group were hand-sutured. All the small bowels were subjected to leak pressure testing later on. The speed of closure and bursting pressure were compared. The 50 porcine small bowels closed by the high-frequency welding device showed a success rate of 100%. Compared with the hand-sutured group, the bursting pressures of the former were significantly lower (Pwelding device has higher feasibility in closing the small bowel. PMID:25868254

  8. 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

  9. MRI of small bowel Crohn's disease: determining the reproducibility of bowel wall gadolinium enhancement measurements

    International Nuclear Information System (INIS)

    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.)

  11. SMALL BOWEL - A RARE METASTASIS FROM OVARIAN CANCER

    Directory of Open Access Journals (Sweden)

    Maria-Gabriela Ro?ca

    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.

  14. 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)

    AIM: To determine if longer battery life improves capsule endoscopy (CE) completion rates. METHODS: A retrospective study was performed at a tertiary, university-affiliated hospital in Vancouver, Canada. Patients who underwent CE with either PillCam™ SB2 or SB2U between 01/2010 and 12/2013 were considered for inclusion. SB2 and SB2U share identical physical dimensions but differ in their battery lives (8 h vs 12 h). Exclusion criteria included history of gastric or small bowel surgery, endoscopic placement of CE, interrupted view of major landmarks due to technical difficulty or significant amount of debris, and repeat CE using same system. Basic demographics, comorbidities, medications, baseline bowel habits, and previous surgeries were reviewed. Timing of major landmarks in CE were recorded, and used to calculate gastric transit time, small bowel transit time, and total recording time. A complete CE study was defined as visualization of cecum. Transit times and completion rates were compared. RESULTS: Four hundred and eight patients, including 208 (51.0%) males, were included for analysis. The mean age was 55.5 ± 19.3 years. The most common indication for CE was gastrointestinal bleeding (n = 254, 62.3%), followed by inflammatory bowel disease (n = 86, 21.1%). There was no difference in gastric transit times (group difference 0.90, 95%CI: 0.72-1.13, P = 0.352) and small bowel transit times (group difference 1.07, 95%CI: 0.95-1.19, P = 0.261) between SB2U and SB2, but total recording time was about 14% longer in the SB2U group (95%CI: 10%-18%, P < 0.001) and there was a corresponding trend toward higher completion rate (88.2% vs 93.2%, OR = 1.78, 95%CI 0.88-3.63, P = 0.111). There was no statistically significant difference in the rates of positive findings (OR = 0.98, 95%CI: 0.64-1.51, P = 0.918). CONCLUSION: Extending the operating time of CE may be a simple method to improve completion rate although it does not affect the rate of positive findings. PMID:25759536

    Full Text Available The bowel is involved in 3.8 to 37% of women with endometriosis, out of which nearly 1% present with signs of bowel obstruction to the surgeon. This report describes a case of acute small bowel obstruction in a 23 years old woman. The patient gave a history of intermittent episodes of pain abdomen and abdominal distension for the past 1 year with significant loss of weight. The menstrual cycles were normal. Although there was no history of Tuberculosis, a positive history of contact was present. The clinical and biochemical picture was suggestive of peritonitis. CECT of the abdomen revealed a long segment distal ileal stricture. With a provisional diagnosis of Tubercular Ileo-Caecal stricture perforation, a midline exploratory laparotomy was performed. The procedure consisted of right limited hemicolectomy and primary ileo-ascending anastomosis with a proximal loop ileostomy. Ileostomy was done to allow the healing of distal anastomosis and closure was done after 4 weeks. Histopathology of the resected segment of ileum revealed subserosal endometriosis. Postoperatively, the patient was not given any hormonal therapy and recovery has been uneventful over the past 1 year of follow up. [Int J Reprod Contracept Obstet Gynecol 2016; 5(3.000: 907-912

  17. Application of nasointestinal decompression intubation in small bowel obstruction

    International Nuclear Information System (INIS)

    Objective: To evaluate the nasointestinal decompression intubation in acute small intestinal obstruction. Methods: Ten patients with acute small bowel obstruction received nasointestinal decompression intubation under x-ray guidance. The nasointestinal decompression tube passing over a guidewire was inserted into small intestine near Tres ligament or further down distally with assistance of patients adopting in multi-physical positions. Results: The intubation of nasointestinal decompression tubes into small intestine was technically successful in all patients with average procedural time of 16 min. (10-35 min). After placement of the tube, all patients obtained various degrees of symptoms relief including abdominal pain, distention, vomiting, etc. Four patients with simple adhesive obstruction recovered completely and the tube was removed 2 weeks later. Three patients were referred to surgical operation, and 3 others gave up for further treatment. There were no complications such as bleeding or perforation related to intubation. Conclusion: Nasointestinal decompression intubation under guidance of X-ray is rather simple, less time consuming, especially with high efficiency for preoperative gastrointestinal decompression and treating simple adhesive bowel obstruction; ought to be recommended.

    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.

    Full Text Available Abstract Introduction This report describes a rare complication of colonoscopy and reviews the literature with regard to other rare causes of acute abdominal presentations following colonoscopy. Case presentation After a therapeutic colonoscopy a 60-year-old woman developed an acute abdomen. At laparotomy she was discovered to have small bowel obstruction secondary to incarceration through a congenital band adhesion. Conclusion Although there is no practical way in which such rare complications can be predicted, this case report emphasises the wide array of pathologies that can result in acute abdominal symptoms following colonoscopy.

    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

    2015-07-01

    Full Text Available Purpose: To evaluate ultrasonographic accuracy in the differentiation of a bezoar from feces in a small bowel obstruction showing feces-like material just proximal to the transitional zone in abdominal computed tomography (CT. Methods: This study included 14 patients who showed feces-like material just proximal to the transitional zone, among 302 patients diagnosed with small bowel obstruction on abdominal CT. The diagnostic signs of a bezoar on ultrasonography included an arc-like surfaced intraluminal mass, posterior acoustic shadow and twinkling artifacts. The diagnostic performance of ultrasonography in each patient was compared with a final diagnosis that was surgically or clinically made. Results: Among the 14 patients, seven were ultrasonographically diagnosed as having a bezoar, and five of the seven were surgically diagnosed as having a phytobezoar. The remaining two of the seven showed complete symptomatic improvement before surgery. The other seven patients were ultrasonographically diagnosed as not having a bezoar. Among them, six patients were conservatively treated with symptomatic improvement, suggesting the absence of a bezoar. The remaining one patient was confirmed not to have a bezoar during adhesiolysis. In all patients, the ultrasonographic diagnosis agreed with the clinically confirmed diagnosis. Conclusion: Ultrasonography might be an accurate method for the differential diagnosis of feces-like material just proximal to the transitional zone in abdominal CT. It can help radiologists to quickly and easily diagnose a bezoar.

    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. .

  6. Direct diverticular inguinal hernia

    International Nuclear Information System (INIS)

    Nineteen patients with direct diverticular inguinal hernia (DDIH) were examined with herniography and surgically explored. A lump medially in the groin and pain were the prominent clinical manifestations in 18 patients. Physical examination indicated the presence of a DDIH in 6 patients. In 16 patients herniography revealed hernial sacs protruding from the supravesical fossa in 5 and from the medial inguinal fossa in 11. At operation a circumscribed defect was found in the transverse fascia laterally and cranially to the pubic tubercle in all patients. In 16 patients peritoneal hernial sacs were demonstrated at surgery while in 3 only lipomas (fatty hernia) were contained within the defect. In our opinion DDIH is a specific variety of inguinal hernia with a fairly typical clinical presentation and radiographic appearance but probably often overlooked at surgery. (orig.)

  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.

    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 intolera...

    Diverticulosis, diverticular disease and diverticulitis have come into focus again because new aspects concerning diagnosis, risk factors and treatment arose only recently which prompted a new Guideline released by the DGVS and DGAV summarising the current evidence. Along with the guideline's essentials for medical practice a diagnosis of diverticulitis is considered unsatisfactory unless a cross-sectional imaging method (either ultrasonography [US] or computed tomography [CT] ) has proven that the clinical findings and inflammation (CRP considered superior to WBC and temperature) are due to diverticular inflammation. For reasons of practicability and considering relevant legislation for radiation exposure protection, US is the primary - and usually effectual - diagnostic method of choice as it is equipotent to CT. While US offers better resolution and enables precise imaging exactly at the location of pain as well as reiterative application, the latter implies advantages in the case of a deep abscess or diverticulitis in difficult locations (e.?g. the small pelvis). Clinical evidence and laboratory and imaging findings allow for distinguishing a large number of differential diagnoses and also form the basis of a new classification (classification of diverticular disease, CDD) which comprises all forms of diverticular disease, from diverticulosis to bleeding and to the different facettes of diverticulitis. This classification -which should be applied in any patient with the diagnosis of diverticular disease- is independent of specific diagnostic preferences and applicable both to conservative and operative treatment options. While the number of recurrent episodes is no longer a significant indicator for surgery in diverticulitis, severity and?/?or complications determine treatment options along with the patients preferences. According to first data, conservative treatment may waive antibiotics under certain circumstances, however they are indispensible in complicated disease or patients bearing risk factors. Spasmoanalgetics and supportive fluid supply are individually necessary, and avoidance of potentially aggravating medications (e.?g. NSAIDS) appears advisable, but many suggestions (nil by mouth, bed rest, laxatives) come along without an adaequate body of evidence. Similarly medical advice concerning prevention and secondary prophylaxis relies mainly on epidemiological plausibility. Because minor perforations (CDD type 2?a) as well as recurrent episodes of uncomplicated diverticulitis and even some abscesses?>?1?cm (CDD type 2?b) respond favourably to medical treatment, the timely indication for surgery in these cases requires precise classification along with a close surveillance in trustful cooperation between the gastroenterologist and the surgeon.

    Postoperative adhesion is a frequent problem in patients undergoing surgery. In particular, gastrectomy is associated with a high risk of bowel obstruction. However, there are few reports of small bowel obstruction (SBO) after gastrectomy in the English-language literature. We reviewed the literature to assess the effectiveness of various techniques for preventing adhesion in patients treated with gastrectomy. We assumed that strategies used to prevent postoperative adhesion associated with colorectal surgery, cholecystectomy, appendectomy and gynecologic procedures are similar to those used in gastrectomy. We therefore reviewed reports on the prevention of postoperative SBO in any abdominal surgical procedure, focusing especially on gastrectomy. General intraoperative preventive techniques, such as the use of starch-free gloves, saline irrigation at a temperature below 37 °C and laparoscopic techniques whenever possible, may reduce the incidence of SBO in patients with gastric cancer who undergo gastrectomy. If preserving the omentum is unrelated to the survival rate of patients with gastric cancer, this technique should be recommended for preventing postoperative SBO. The use of hyaluronic acid/carboxymethylcellulose bioabsorbable membranes should also be considered in patients undergoing gastrectomy. However, demonstrating the advantages of bioabsorbable membranes would require larger randomized studies with a longer follow-up period. PMID:25542082

    2003-01-01

    We report the case of a 33-year-old woman whose medical history included three normal pregnancies without previous abdominal or pelvic surgery. She presented with small bowel obstruction. An abdominal computed tomography (CT) scan study revealed air fluid levels in the pelvis. Laparoscopic exploration revealed a viable ileal loop incarcerated through the mesoligamentum teres. The intestinal loop was reduced and the broad ligament defect was closed with a laparoscopic absorbable clip. Among internal hernias, hernias through a defect in the broad ligament represent only 4-7%. Defects within the broad ligament can be either congenital (ruptured cystic structures reminiscent of the mesonephric or mullerian ducts) or secondary to operative trauma, pregnancy and birth trauma, or prior pelvic inflammatory disease. CT scan may be diagnostic by showing incarceration of a dilated intestinal loop in the Douglas pouch with air fluid levels. This is the first reputed case of a totally laparoscopic repair of a bowel incarceration through a broad ligament defect. PMID:12399855

    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.

  15. Utility of CT in the diagnosis and management of small-bowel obstruction in children

    International Nuclear Information System (INIS)

    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.)

    Full Text Available The entity of nonspecific granulomatous inflammatory lesions(NSGIL of the small bowel is a diagnostic and therapeutic dilemma. Data of 52 histopathologically proven cases of NSGIL seen by us between 1986 and 1991 were analysed. All these patients presented with either intestinal obstruction or perforation. They were thoroughly evaluated and investigated for tuberculosis. Of the 52 patients, 6 patients received antitubercular therapy (ATT before and after surgery and 32 patients only after surgery. Fourteen patients did not receive ATT. Surgical procedures undertaken included stricturoplasty, resection/anastomosis and simple suturing of perforation. No complications were seen in patients who received ATT; however, six of 14 patients who did not receive ATT developed wound sepsis and 2 developed partial wound dehiscence. Many of these NSGIL lesions could be tuberculous in etiology though typical caseating granulomas were not seen.

  19. An unusual cause of small bowel obstruction: Gossypiboma – case report

    Directory of Open Access Journals (Sweden)

    Inceoglu Resit

    2003-09-01

    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.

  20. The clinical value of MRI in the diagnosis of small-bowel diseases

    International Nuclear Information System (INIS)

    Objective: To evaluate the feasibility and the clinical value of MRI in the diagnosis of small-bowel disease. Methods: Sixty-three patients with suspected small-bowel diseases and 3 volunteers without signs of small bowel disease underwent MRI examination. Thirty-one patients whose diagnoses were confirmed by pathology or clinical results were categorized into two groups (neoplastic and nonneoplastic). The conspicuity of bowel wall, the sensitivity of MRI in detecting small-bowel lesions, and the accuracy rate of diagnosis were calculated. The average bowel wall thickness between the two groups was assessed by using Wilcoxon signed-rank test. Enlarged mesenteric lymph nodes, mesenteric infiltration, and small-bowel stenosis were analyzed by using Fisher's exact test in each group respectively. Results: MRI examinations of all 66 subjects were successfully performed. Images were rated on a continuous 4-point scale. Sixty-two cases (93.9%) were scored as 2 or 3. The diagnoses of 31 patients (neoplastic group (n=10) and nonneoplastic group (n=21) were confirmed by pathology or clinical results. The sensitivity, accuracy of MRI in identifying small bowel diseases were 100% (31/31) and 77.4% (24/31) respectively. The average bowel wall thickness of the two groups was 23 mm (7.0-65.0 mm) and 5 mm(2.0-35.0 mm) respectively, and there was a statistically significant difference between the two groups (Z=-2.949, P0.05). Conclusion: MRI can depict the location and extension of the small-bowel disease accurately and it is an effective method in the diagnosis of small-bowel disease. (authors)

  1. Technical quality of CT colonography in relation with diverticular disease

    International Nuclear Information System (INIS)

    Objective: The aim of the study is to explore how the technical quality of the examination was affected by diverticular disease. Materials and methods: We retrospectively evaluated a consecutive series of 78 subjects who underwent CTC for screening (n = 58) or staging (n = 20) colorectal cancer, 38 of them (49%) after an incomplete optical colonoscopy. Patients were administered a mild laxative and a iodinated contrast material for fecal tagging. We scored both the bowel preparation and the overall colon distension as poor, good, or optimal and measured the mean sigmoid colon diameter. We counted the number of diverticula and classified patients as having or not a severe diverticular disease (SDD). The number of the prompts of computer aided diagnosis (CAD) per patient was also considered. Mann–Whitney U and ?2 tests were performed. Results: No CTC complications occurred. The bowel cleansing was poor in 8 (10%) patients, good in 29 (37%) and optimal in 41 (53%); colon distension was poor in 7 (9%) patients, good in 38 (49%), and optimal in 33 (42%). Fifty-four (69%) showed diverticula and 30 (38%) had an SDD. Bowel cleansing and distension were not significantly impaired by neither diverticula (p > 0.590) nor the SDD (p > 0.110). Mean sigmoid colon diameter was reduced in presence of diverticula (28 mm versus 23 mm, p = 0.009) or SDD (26 mm versus 22 mm, p = 0.016). The mean number of CAD prompts per patient was not significantly increased by the presence of SDD (p = 0.829). Conclusions: Bowel cleansing and distension at CTC were not influenced by the presence of diverticular disease.

  2. 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

    Full Text Available Background and aim. Small intestinal bacterial overgrowth is encountered in bowel disorders, including irritable bowel symptoms. Low degrees of inflammation have been recently reported in the irritable bowel syndrome. We looked for the association between intestinal inflammation and small intestinal bacterial overgrowth in irritable bowel syndrome.Methods. Small intestinal bacterial overgrowth was assessed by the H2 glucose breath test in 90 consecutive patients with irritable bowel syndrome. A check-up of the oral cavity was carried out before the breath testing.  Further on, the patients were classified into two groups, positive and negative, at the breath test. Then they were tested for intestinal inflammation with a fecal test for calprotectin. We used a semiquantitative test for this study. Both groups were compared for the association of intestinal inflammation with small intestinal bacterial overgrowth.Results. A number of 24/90 (26.7% patients with irritable bowel syndrome had small intestinal bacterial overgrowth. A positive test for intestinal inflammation was significantly more frequent in patients with irritable bowel syndrome and small intestinal bacterial overgrowth (chi2: p<0.05.Conclusions. Small intestinal bacterial overgrowth is present in almost one quarter of patients with irritable bowel syndrome. It is significantly associated with intestinal inflammation.

  4. 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.)

    International Nuclear Information System (INIS)

    Peutz-Jeghers syndrome (PJS) is a rare, though well-described, hereditary polyposis syndrome associated with mucocutaneous pigmentation that typically presents in the second decade of life with complications related to intestinal polyps. We present two cases of teenaged girls presenting with small-bowel intussusceptions within a 3-month period. Sonographic examinations readily revealed small-bowel intussusceptions with secondary small-bowel obstruction. In both the symptoms were less severe than one would expect given the underlying pathology found at subsequent surgery. Sonographic imaging with pathologic correlation is provided. (orig.)

    2011-10-01

    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.

    Goblet cell carcinoid tumor of the appendix (GCTA) is a tumor with histological features of both adenocarcinoma and carcinoid tumors. The most common clinical presentation of GCTA is acute appendicitis, although small bowel obstruction has been reported as a rare clinical symptom of GCTA. However, to the best of our knowledge, the CT feature of small bowel obstructions in patients with GCTA has not been reported to date. Here, we present a case of small bowel obstruction in a patient with GCTA caused by extensive tumor infiltration at the terminal ileum and distal ileum.

    The effects of the volume of irradiated small bowel on late small-bowel tolerance was studied, taking into account the equivalent total dose ant type of pre-irradiation surgical procedure. A method was developed to estimate small-bowel volumes in the high-bowel volumes were measured for three-field and AP-PA pelvic treatments (165 cm{sup 3} and 400 cm{sup 3}, respectively), extended AP-PA treatment of para-aortic and iliac nodes (1000 cm{sup 3}). In a retrospective study of 111 patientst irradiated after surgery for rectal or recto-sigmoid cancer to a dose of 45-50 Gy in 5 weeks, extended AP-PA pelvic treatment (n = 27) resulted in a high incidence of severe small-bowel complications (37%), whereas for limited (three-field) pelvic treatment (n = 84) the complication rate was 6%. These complication data together with data from the literature on postoperative radiation-related small-bowel complications were analysed using the maximum likelihood method to fit the data to the logistic form of the dose-response relation, taking the volume effect into account by a power law. The analysis indicated that the incidence of radiation-related small-bowel compllications was higher after rectal surgery than after other types of surgery, which might be explained by the development of more adhesions. For both types of surgery a volume exponent of the power-law of 0.26 {plus minus} 0.05 was established. This means that if the small-bowel volume is increased by a factor of 2, the total dose has to be reduced by 17% for the same incidence of small-bowel complications.

    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.

    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.

  11. Glucagon in the scintigraphic diagnosis of small-bowel hemorrhage by Tc-99m-labeled red blood cells

    International Nuclear Information System (INIS)

    Twelve patients undergoing scintigraphy with Tc-99m-labeled red blood cells (RBC) exhibited abnormal small-bowel activity and were given glucagon to assess its role in detecting bleeding from the small bowel. Six demonstrated focal accumulation of activity which was not identified prior to glucagon. Endoscopy, barium studies, angiography, and colonoscopy located the small-bowel bleeding site in 4 patients; in the other 2, studies of the colon failed to show the bleeding site and the origin was presumed to be the small bowel. The authors suggest that intravenous glucagon can be beneficial as an adjuvant to Tc-99m-RBC when diagnosing bleeding from the small bowel

    Coffee enemas are believed to cause dilatation of bile ducts and excretion of bile through the colon wall. Proponents of coffee enemas claim that the cafestol palmitate in coffee enhances the activity of glutathione S-transferase, an enzyme that stimulates bile excretion. During video capsule endoscopy (VCE), excreted bile is one of the causes of poor preparation of the small bowel. This study aimed to evaluate the feasibility and effect of coffee enema for preparation of the small bowel during VCE. In this pilot study, 17 of 34 patients were assigned to the coffee enema plus polyethylene glycol (PEG) 2 L ingestion group, whereas the 17 remaining control patients received 2 L of PEG only. The quality of bowel preparation was evaluated in the two patient groups. Bowel preparations in the proximal segments of small bowel were not differ between two groups. In the mid and distal segments of the small intestine, bowel preparations tend to be better in patients who received coffee enemas plus PEG than in patients who received PEG only. The coffee enema group did not experience any complications or side effects. Coffee enemas may be a feasible option, and there were no clinically significant adverse events related to coffee enemas. More prospective randomized studies are warranted to improve small bowel preparation for VCE. PMID:25136541

    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

    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 (TV{sub bldder}), obesity index and high dose volume of small bowel (small bowel volume irradiated at 90% of prescribed dose, HDV{sub sb}), low dose volume of small bowel (small bowel volume irradiated at 33% of prescribed dose, LDV{sub sb}). The result shows, gender, WHR and status of pre operative or post operative do not greatly affect HDV{sub sb} and LDV{sub sb}. Statistical result shows, there are significant correlation between HDV{sub sb} and BMI (p<0.04), HDV{sub sb} and TV{sub bladder} (p<0.01), LDV{sub sb} and TV{sub bladder} (p<0.01). BMI seems to correlate with HDV{sub sb} but does not with LDV{sub sb} (p>0.05). There are negative correlation between HDV{sub sb} and BMI, TV{sub bladder} and HDV{sub sb}, TV{sub bladder} and LDV{sub sb} . Especially, BMI group1 has more effective and negative correlation with HDV{sub sb} (p=0.027) than in BMI group 2. In the case of BMI group 1, TV{sub bladder} has significant negative correlation with HDV{sub sb} and LDV{sub sb} (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.

    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.)

    Objective Several studies suggested that colonic microbiota have impacts on irritable bowel syndrome (IBS) patients. However, the knowledge about the association of small intestine (SI) microbiota with IBS is limited. We aimed to investigate the gut microbiota composition of SI and stool in IBS patients. Materials and methods Biopsies of jejunum mucosa by balloon-assisted enteroscopy and faecal samples from 28 IBS patients and 19 healthy controls were analysed by next-generation sequencing method. Results The three major phyla in SI microbiota of case/control groups were Proteobacteria (32.8/47.7%), Bacteroidetes (25.2/15.3%), and Firmicutes (19.8/11.2%), and those of stool were Bacteroidetes (41.3/45.8%), Firmicutes (40.7/38.2%), and Proteobacteria (15.4/7.1%). Analysis based on the family level, IBS patients had a higher proportion of Veillonellaceae (mean proportion 6.49% versus 2.68%, p = 0.046) in stool than controls. Prevotellaceae was more abundant in IBS patients than in control group (14.27% versus 6.13%, p = 0.023), while Mycobacteriaceae (0.06% versus 0.17%, p = 0.024) and Neisseriaceae (6.40% versus 8.94%, p = 0.038) was less abundant in IBS patients' jejunal mucosa than those in controls. This less abundant jejunal Neisseriaceae was associated with more severe IBS (p = 0.03). The ratio of Firmicutes to Bacteroidetes in the stool of IBS-diarrhoea type patients was approximately three-fold higher, and the ratio of Firmicutes to Actinobacter in SI of IBS-mixed type patients was about nine-fold higher than healthy subjects. Conclusion Higher abundance of colonic Veillonellaceae and SI Prevotellaceae, and lower amount of oral cavity normal flora in proximal SI were found in IBS patients. We may manipulate these bacteria in IBS patients in future studies (ClinicalTrial.gov Number NCT01679730). PMID:26595305

    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. ...

    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.

    Coffee enemas are believed to cause dilatation of bile ducts and excretion of bile through the colon wall. Proponents of coffee enemas claim that the cafestol palmitate in coffee enhances the activity of glutathione S-transferase, an enzyme that stimulates bile excretion. During video capsule endoscopy (VCE), excreted bile is one of the causes of poor preparation of the small bowel.

    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.

    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.)

    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.

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.

    MRI of the small bowel is a new method for the assessment of inflammatory bowel diseases. However, inflammatory bowel disease can affect both the small and large bowel. Therefore, our goal was to assess the feasibility of displaying the small bowel and colon simultaneously by MR imaging. Eighteen patients with inflammatory bowel disease were studied. For small bowel distension, patients ingested a solution containing mannitol and locust bean gum. Furthermore, the colon was rectally filled with water. MR examinations were performed on a 1.5-T system. Before and after intravenous gadolinium administration, a T1w data set was collected. All patients underwent conventional colonoscopy as a standard of reference. The oral ingestion and the rectal application of water allowed an assessment of the small bowel and colon in all patients. By means of MRI (endoscopy), 19 (13) inflamed bowel segments in the colon and terminal ileum were detected. Furthermore, eight additional inflammatory lesions in the jejunum and proximal ileum that had not been endoscopically accessible were found by MRI. The simultaneous display of the small and large bowel by MRI is feasible. Major advantages of the proposed MR concept are related to its non-invasive character as well as to the potential to visualize parts of the small bowel that cannot be reached by endoscopy. (orig.)

  15. The value of MR enteroclysis with air infusion in the diagnosis of small bowel disease

    International Nuclear Information System (INIS)

    Objective: To investigate the value of MR enteroclysis with air infusion in the diagnosis of small bowel disease. Methods: Sixteen patients with suspected small bowel disease, but without acute inflammatory disease or bowel obstruction, received MR enteroclysis with air infusion. There were 12 males and 4 females, and their age ranged from 17 to 75 years. 10 patients had abdominal pain, 4 with melena or blood stool, and 2 with diarrhea. The longest course was 7 years, and the shortest 1 week. Before MR imaging, a nasoenteric catheter was inserted into the distal part of duodenum, and about 1000 ml of air was infused through the tube to distend the small bowel. 20 mg of IV anisodamine was given to reduce small-bowel peristalsis. All patients were imaged with fat-saturated Gd-DTPA enhanced coronal and axial T1-weighted spin-echo (SE) sequence and fast spoiled gradient echo (FSPGR) sequence. Comparison between the diagnosis of MRI and the results of surgery, pathology or clinic was performed to assess the sensitivity and specificity of MRI. Results: 5 cases were normal, 6 with Crohn disease, 2 with gastric intestinal stromal tumor (GIST), and 1 each of lymphoma, tuberculosis and irritable bowel syndrome. The lumen of normal small bowel in MR enteroclysis was no signal, the wall was outlined as middle signal by intraluminal air and surrounding air-distended bowel and was between 1-3 mm thick, and the diameter of the lumen was between 17-28 mm. Crohn disease showed segmental mural thickening, increased enhancement, luminal stricture, and even extraluminal inflammatory mass or fistula. Intestinal tuberculosis invaded the distal section of ileum, cecum, and the proximal ascending colon, the wall thickened and enhanced apparently, and cecum and proximal ascending colon shortened. GIST showed a mass that was iso-signal on T1WI, high signal on T2WI, and enhanced significantly after IV Gd-DTPA. 1 recurrent lymphoma of ileum showed mural thickening and increased enhancement but no stenosis. 1 irritable bowel syndrome is disfunction, so its shape and signal is normal. Except 1 Crohn disease, which showed a large mass, was misdiagnosed as lymphoma and no abnormality was found in 1 irritable bowel syndrome, the other diagnosis of MRI was correct. The sensitivity in diagnosing small intestinal disease was 100%, and the specificity was 83%. Conclusion: MR enteroclysis with air infusion is a sensitive method in diagnosing the small bowel disease, especially in Crohn disease and tumor. It can clearly display the mural thickening and the extraluminal inflammatory mass

    Since 1968 the inflammatory stage of diverticular disease (acute and chronic diverticulitis) has been treated with tetracosactrin in one practice. This paper reviews 100 episodes treated in this way and compares these with 50 episodes treated with rest in bed and dietary measures. Abatement of pyrexia, swelling and tenderness, as well as relief of the symptoms of pain and malaise, were usually found to occur within 24 hours of the administration of tetracosactrin zinc (1 mg) intramuscularly. ...

    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.

  18. 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

  20. 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

    During pregnancy, abdominal pain can be caused by both obstetric and non-obstetric causes. Non-obstetric causes of severe abdominal pain during pregnancy must always be considered. Complete bowel obstruction caused by an internal hernia is rare in obstetric surgical patients. Delays in diagnosis can occur due to non-specific signs and symptoms which can be present in normal pregnancy, and a reluctance to operate on the pregnant patient.

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

    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.

  4. 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

    Dermatitis herpetiformis (DH) is an extraintestinal manifestation of coeliac disease. Untreated coeliac disease patients are known to have transglutaminase 2 (TG2)-targeted IgA deposits in the small bowel mucosa. To evaluate whether similar intestinal IgA deposits are also present in DH and whether the deposits disappear with gluten-free diet, 47 untreated and 27 treated DH patients were studied. Seventy-nine percent of untreated and 41% of the treated DH patients had TG2-specific IgA deposits in the small bowel, and the presence of the deposits showed a significant association with the degree of small bowel villous atrophy (p < 0.001). Other coeliac-disease related inflammatory markers were also investigated, and the density of small bowel mucosal intraepithelial ??(+) T cells was increased in 91% of untreated and 73% of treated DH patients. The results show that the majority of untreated DH patients have similar gluten-dependent TG2-specific IgA deposits the small bowel mucosa as coeliac disease patients. PMID:24352382

    The video capsule endoscopy is an accurate tool to investigate the entire small bowel. Currently, the nurse actively participates in the procedure from patient preparation to the video download, whereas a gastroenterologist interprets the endoscopic findings. However, few studies recently showed high accuracy of nurses in detecting lesions in the small bowel on video capsule endoscopy recordings. This prospective study aimed to assess the ability of experienced and trained nurses in detecting small bowel lesions as compared with gastroenterologists. Forty-six consecutive video capsule endoscopy procedures were analyzed. Overall, the nurse evaluation was highly (95.6%) accurate in detecting small bowel lesions, with a 100% concordance with the gastroenterologist for the relevant findings. In addition, the absence of lesions was confirmed by the endoscopist in all cases classified as negative by the nurse. Data of this study found that trained nurses, with a large experience in endoscopic features, correctly identified small bowel lesions on video capsule endoscopy recordings. Therefore, a trained nurse may accurately select the thumbnails of all mucosal irregularities that may be faster reviewed by the endoscopist for a final diagnosis. PMID:25831247

    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.

    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.

  10. 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

    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.

    Usually, celiac disease has a benign course, though the overall morbidity and mortality have increased. Treatment with a gluten-free diet restores the damaged intestinal mucosa. In rare cases a small bowel adenocarcinoma develops. Unfortunately, the clinical presentation is not always recognized and prognosis is bad. We present a 69-year-old man with a history of dermatitis herpetiformis who presented to our tertiary center for a second opinion for a suspected gastric motility disorder. This diagnosis was based on the combination of upper abdominal pain for over 2 years and repetitive episodes of vomiting. Immediately after referral, celiac disease was diagnosed and a gluten-free diet was started. In the next half year of follow-up, additional anemia and weight loss developed and eventually a small bowel adenocarcinoma was diagnosed. Revision of a small bowel follow-through, which had been performed 2 years earlier, showed that the tube had been positioned just distal from the process. Therefore, this diagnosis had not been made at that time. Unfortunately, curative therapy was not possible and the patient died a few months later. In conclusion, all patients with dermatitis herpetiformis have a gluten-sensitive enteropathy and should be treated with a gluten-free diet. Next to this it is important to notice that patients with celiac disease have an increased risk of developing a small bowel malignancy. Unexplained upper abdominal pain, weight loss and anemia should lead to additional investigations to exclude a small bowel malignancy in these patients. At last, the diagnosis of a small bowel carcinoma is difficult. Together with the radiologist, the optimal techniques for visualization of this malignancy should be considered. PMID:22379467

  13. 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

    A new method employing 99mTc-labeled pellets for determination of the gastric emptying rate and small bowel transit time is described. The participants were six normal subjects and 16 patients with irritable bowel syndrome (eight with diarrhea and eight with obstipation as the primary complaint). The gastric emptying rate was the same in the three groups. The patients in the obstipation group had a significantly longer small bowel transit time than the normals (P less than 0.02) and the patients in the diarrhea group (P less than 0.01). There was no demonstrable difference between the small bowel transit time in the normals and in the patients in the diarrhea group.

    Full Text Available O termo diverticulite "complicada" é reservado para a doença diverticular complicada por sangramento, abscesso, peritonite, fístula ou obstrução intestinal. A hemorragia é melhor tratada por angioembolização (radiologia intervencionista).

A diverticulite (inflamação) pode ser tratada somente com antibióticos, anti-inflamatórios, combinados com repouso e medidas de higiene. 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.

    2002-08-01

    Full Text Available Abstract Background Existing animal models provide only indirect information about the pathogenesis of infections caused by indigenous gastrointestinal microflora and the kinetics of bacterial translocation. The aim of this study was to develop a novel animal model to assess bacterial translocation and intestinal barrier function in vivo. Methods In anaesthetized male Wistar rats, 0.5 ml of a suspension of green fluorescent protein-transfected E. coli was administered by intraluminal injection in a model of small bowel obstruction. Animals were randomly subjected to non-ischemic or ischemic bowel obstruction. Ischemia was induced by selective clamping of the terminal mesenteric vessels feeding the obstructed bowel loop. Time intervals necessary for translocation of E. coli into the submucosal stroma and the muscularis propria was assessed using intravital microscopy. Results Bacterial translocation into the submucosa and muscularis propria took a mean of 36 ± 8 min and 80 ± 10 min, respectively, in small bowel obstruction. Intestinal ischemia significantly accelerated bacterial translocation into the submucosa (11 ± 5 min, p E. coli were visible in frozen sections of small bowel, mesentery, liver and spleen taken two hours after E. coli administration. Conclusions Intravital microscopy of fluorescent bacteria is a novel approach to study bacterial translocation in vivo. We have applied this technique to define minimal bacterial transit time as a functional parameter of intestinal barrier function.

    Irritable bowel syndrome (IBS) is a common condition characterized by abdominal pain or discomfort, bloating, and altered stool form and passage. Small intestinal bacterial overgrowth (SIBO) is a condition in which there is overgrowth of bacteria in small bowel in excess of 105 colony forming units per milliliter on culture of the upper gut aspirate. Frequency of SIBO varied from 4%-78% among patients with IBS and from 1%-40% among controls. Higher frequency in some studies might be due to fa...

    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

    Small-bowel obstruction due to foreign bodies is unusual in adults. Intestinal obstruction is occasionally caused by pits, bezoars, endoscopy capsules, and gastrostomy tube buttons. We report a rare case of distal small-bowel obstruction due to dental impression material. Avoidance of this potentially life-threatening complication may be achieved by increased vigilance in accounting for all impression material when dental impression trays are removed. Early detection of swallowed dental material may afford endoscopic removal from the stomach, thus preventing intestinal obstruction. PMID:20070020

  2. 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

    Small bowel tolerance is a major dose-limiting factor in treating the pelvis with radiation therapy (RT). The use of small bowel contrast during RT simulation is one technique used to localize the bowel and identify the treatment plan that would exclude the greatest volume. To determine the influence of treatment planning with oral contrast on gastrointestinal injury, acute and chronic small bowel morbidity was analyzed in 115 patients with endometrial and rectal carcinoma who received postoperative radiation therapy at the Fox Chase Cancer Center. Mean and median time of follow-up were 31 and 27 months, respectively. Acute diarrhea was seen in 82% of the patient population. Ten percent of patients experienced major complications requiring hospitalization. Ninety-three percent of patients simulated without contrast experienced side effects compared to 77% of patients simulated with contrast (p = .026). There was an increased incidence of chronic complications in patients who were not simulated with contrast dye (50% vs 23%, p = .014). Median duration of minor side effects was 4 months for patients planned without oral contrast and 1 month for patients who had contrast at the time of simulation (p = .036). The superior aspect of the treatment field was determined to be at a more inferior location in patients simulated with contrast, thereby excluding small bowel from treatment. Seventy-four percent of patients simulated without contrast had the upper border of the field placed at the superior aspect of the sacroiliac joint or above, compared to only 40% of patients planned with oral contrast (p = .002). This study has demonstrated decreased complications (both overall and chronic) as well as a change in the location of the treatment field with the use of small bowel contrast.

    Perforation of the gastrointestinal tract by ingested foreign bodies is extremely rare in otherwise healthy patients, accounting for ingested foreign bodies could cause small bowel perforation through a hernia sac, Meckel's diverticulum, or the appendix, all of which are uncommon. Despite their sharp ends and elongated shape, bowel perforation caused by ingested fish bones is rarely reported, particularly in patients without intestinal disease. We report a case of 57-year-old female who visited the emergency room with periumbilical pain and no history of underlying intestinal disease or intra-abdominal surgery. Abdominal computed tomography and exploratory laparotomy revealed a small bowel micro-perforation with a 2.7-cm fish bone penetrating the jejunal wall. PMID:24587641

    Introduction In blunt abdominal trauma, lesions of the small bowell and mesentery are often underdiagnosed; although unusual, they represent the third most injured organ, with increasing morbidity and mortality. Presentation of case The authors present the case of a 68 years old male, admitted to the emergency department after being hit by a bale of straw, weighing around 300 kg, in the abdomen. After successful ressuscitation, a CT scan was performed, suggesting hemoperitoneum because of vascular lesion of the right colon bleeding. An exploratory laparotomy was performed, confirming the presence of blood in the abdominal cavity and identifying jejunal perforation, an apparently innocent hematoma of the small bowel mesentery (beside the bowel wall) distally to the first lesion and a laceration of the sigmoid serosa; a segmental jejunal resection and suture of the colon serosa were performed. In the early post-operative period, an enteric discharge was noticed, mandating surgical reexploration; a previously unnoticed bowel perforation, in the mesenteric border where the hematoma was identified, justified an additional enterectomy, after what the patients recovery progressed uneventfully. Discussion In this case, a sudden increase in abdominal pressure could explain that missed rupture of the mesenteric border of the jejunum, also causing the mesenteric hematoma, or, in spite of that, a state of low perfusion could have lead to total wall ischemia of an already irrigation compromised segment. Only noted after surgical exploration, despite prior evaluation with a computed tomography. Small bowell and mesenteric injuries are potentially missed due to decreased exploratory laparotomies for blunt abdominal trauma. Conclusion Although uncommon, small bowel and mesenteric injuries are associated with high morbidity and mortality. High clinical suspicion is essential for an early diagnosis PMID:25576959

    Substantial water fluxes across the small intestine occur during digestion of food, but so far measuring these has required invasive intubation techniques. This paper describes a non-invasive magnetic resonance imaging (MRI) technique for measuring small bowel water content which has been validated using naso-duodenal infusion. Eighteen healthy volunteers were intubated, with the tube position being verified by MRI. After a baseline MRI scan, each volunteer had eight 40 ml boluses of a non-absorbable mannitol and saline solution infused into their proximal small bowel with an MRI scan being acquired after each bolus. The MRI sequence used was an adapted magnetic resonance cholangiopancreatography sequence. The image data were thresholded to allow for intra- and inter-subject signal variations. The MRI measured volumes were then compared to the known infused volumes. This MRI technique gave excellent images of the small bowel, which closely resemble those obtained using conventional radiology with barium contrast. The mean difference between the measured MRI volumes and infused volumes was 2% with a standard deviation of 10%. The maximum 95% limits of agreement between observers were -15% to +17% while measurements by the same operator on separate occasions differed by only 4%. This new technique can now be applied to study alterations in small bowel fluid absorption and secretion due to gastrointestinal disease or drug intervention.

    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 littl...

    Full Text Available AIM: To determine the effect of Prepacol®, a combination of sodium phosphate and bisacodyl, on transit and quality of capsule endoscopy (CE.METHODS: Fivety two consecutive patients were included in this prospective study. CE was performed following a 12 h fasting period. Twenty six patients were randomized for additional preparation with Prepacol®. The quality of CE was assessed separately for the proximal and the distal small bowel by 3 experienced endoscopists on the basis of a graduation which was initially developed with 20 previous CE.RESULTS: Preparation with Prepacol® accelerated small bowel transit time (262 ± 55 min vs 287 ± 97 min, but had no effect on the quality of CE. Visibility was significantly reduced in the distal compared to the proximal small bowel.CONCLUSION: The significantly reduced visibility of CE in the distal small bowel allocates the need for a good preparation. Since Prepacol® has no beneficial effect on CE the modality of preparation and the ideal time of application remains unclear. Further standardized examinations are necessary to identify sufficient preparation procedures and to determine the impact of the volume of the preparation solution.

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

    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.

    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.

    Full Text Available Abstract Background Inflammation and immune activation have repeatedly been suggested as pathogentic factors in irritable bowel syndrome (IBS. The driving force for immune activation in IBS remains unknown. The aim of our study was to find out if the obligate intracellular pathogen Chlamydia could be involved in the pathogenesis of IBS. Methods We studied 65 patients (61 females with IBS and 42 (29 females healthy controls in which IBS had been excluded. Full thickness biopsies from the jejunum and mucosa biopsies from the duodenum and the jejunum were stained with a monoclonal antibody to Chlamydia lipopolysaccharide (LPS and species-specific monoclonal antibodies to C. trachomatis and C. pneumoniae. We used polyclonal antibodies to chromogranin A, CD68, CD11c, and CD117 to identify enteroendocrine cells, macrophages, dendritic, and mast cells, respectively. Results Chlamydia LPS was present in 89% of patients with IBS, but in only 14% of healthy controls (p C. trachomatis major outer membrane protein (MOMP. Staining for C. pneumoniae was negative in both patients and controls. Chlamydia LPS was detected in enteroendocrine cells of the mucosa in 90% of positive biopsies and in subepithelial macrophages in 69% of biopsies. Biopsies taken at different time points in 19 patients revealed persistence of Chlamydia LPS up to 11 years. The odds ratio for the association of Chlamydia LPS with presence of IBS (43.1; 95% CI: 13.2-140.7 is much higher than any previously described pathogenetic marker in IBS. Conclusions We found C. trachomatis antigens in enteroendocrine cells and macrophages in the small bowel mucosa of patients with IBS. Further studies are required to clarify if the presence of such antigens has a role in the pathogenesis of IBS.

  6. Stagnant loop syndrome resulting from small-bowel irradiation injury and intestinal by-pass

    Stagnant or blind-loop syndrome includes vitamin B12 malabsorption, steatorrhea, and bacterial overgrowth of the small intestine. A case is presented to demonstrate this syndrome occurring after small-bowel irradiation injury with exaggeration postenterocolic by-pass. Alteration of normal small-bowel flora is basic to development of the stagnant-loop syndrome. Certain strains of bacteria as Bacteriodes and E. coli are capable of producing a malabsorption state. Definitive therapy for this syndrome developing after severe irradiation injury and intestinal by-pass includes antibiotics. Rapid symptomatic relief from diarrhea and improved malabsorption studies usually follow appropriate antibiotic therapy. Recolonization of the loop(s) with the offending bacterial species may produce exacerbation of symptoms. Since antibiotics are effective, recognition of this syndrome is important. Foul diarrheal stools should not be considered a necessary consequence of irradiation injury and intestinal by-pass.

    2013-01-01

    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.

  8. 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.

SICUS was performed at the induction phase and at regular time intervals during the follow-up period of 34.7 ± 16.1 mo (range 7-58. Small bowel stenoses were detected by SICUS, endoscopy and MRI.RESULTS: In no case was progression of stenoses or the appearance of new ones seen. Of the 15 patients with stenosis, 5 stopped treatment after the induction phase (2 for no response, 3 for drug intolerance, one of whom showed complete regression of one stenosis. Among the remaining 10 patients, a complete regression of 8 stenoses (1 stenosis in 5 patients and 3 stenoses in one patient was observed after 6-22 infliximab infusions.CONCLUSION: In patients with CD treated with infliximab we observed: (a No progression of small bowel stenosis and no appearance of new ones, (b Complete regression of 1/22 stenosis after the induction phase and of 8/15 (53.3% stenosis after 6-22 infusions during maintenance therapy.

  12. 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.)

    Bowel rupture due to blunt abdominal trauma is no longer rare, and is among the most challenging problems that confront the physicians and radiologists. It is frequently difficult to diagnose because the symptoms may be trivial during the early stage and masked by more obvious, but less lethal injuries. It is well known that the roentgen examination of the abdomen is also of little value to exclude bowel rupture because of infrequency of positive findings and free gas. The plain films of 23 cases of jejunal rupture and 8 cases of ileal rupture were evaluated to sort and diagnostic features of small bowel rupture caused by blunt abdominal trauma. 1. Free intraperitoneal gas was noted in 6 cases of jejunal rupture (26%) and 1 case of ileal rupture (13%), and definite radiological evidence of free intraperitoneal fluid was present in 16 cases of patients (52%). 2. The contour change of bowel loops such as tapering or indentation were seen in 11 cases of patients (36%), and local opacity along the mesenteric root axis was demonstrated in 19 cases of patients (61%). 3. Paralytic ileus was localized to LUQ in jejunal rupture and to mid-abdomen in ileal rupture, and gastric and transverse-colon distension with gas was noticeable especially in jejunal rupture.

    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.

    Bochdalek hernia (BH), a closing defect of the peripheral posterior aspect of the diaphragm, is the commonest of the 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, they 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. PMID:23725897

    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.

  10. Detected peritoneal fluid in small bowel obstruction is associated with the need for surgical intervention.

    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 microvascular injury quantitatively in the small bowel with respect to cardiopulmonary bypass (CPB and related mechanisms.METHODS: In 10 male SD rats, normothermic CPB was established and continued with a flow rate of 100-150 mL/kg per minute for 60 min, while another 10 sham-operated animals served as controls. An approximate 10-cm loop of the terminal ileum was exteriorized for observation by means of intravital fluorescence microscopy. The small bowel microcirculatory network including arterioles, capillaries, and collecting venules was observed prior to CPB, CPB 30 min, CPB 60 min, post-CPB 60 min and post-CPB 120 min. The intestinal capillary perfusion, microvascular permeability and leukocyte adherence were also measured.RESULTS: The systemic hemodynamics remained stable throughout the experiment in both groups. In CPB animals, significant arteriolar vasoconstriction, blood velocity reduction and functional capillary density diminution were found. As concomitances, exaggerated albumin extravasation and increased leukocyte accumulation were also noted. These changes were more pronounced and there were no signs of restitution at the end of the observation period.CONCLUSION: CPB induces significant microcirculatory injury of the small bowel in rats. The major underlying mechanisms are blood flow redistribution and generalized inflammatory response associated with CPB.

    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)

    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.

  17. 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.

    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.

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

    Using breath hydrogen analysis after 139 mmol (50 g) oral lactose load, we investigated the prevalence of lactose malabsorption in 200 Greek adults and examined the relationship between symptoms and small bowel transit time. One hundred and fifty subjects had increased breath hydrogen concentrations (greater than 20 ppm) after the lactose load. In these individuals peak breath hydrogen concentration was inversely related to small bowel transit time (r = 0.63, 6 = 6.854, p less than 0.001) and...

  2. 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.

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

    Hendel, Jakob; Karstensen, John Gásdal

    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.

    Full Text Available Background /Aim: The symptoms of irritable bowel syndrome resemble those of small intestinal bacterial overgrowth (SIBO. The aim of this study was to determine the frequency of SIBO and lactose intolerance (LI occurrence in patients with diarrhea-predominant irritable bowel syndrome (IBS-D according to Rome III criteria. Patients and Methods: In this retrospective case-control study, patients over 18 years of age with altered bowel habit, bloating, and patients who had lactose Hydrogen breath test (H 2 BT done were included. The "cases" were defined as patients who fulfill Rome III criteria for IBS-D, while "controls" were those having chronic nonspecific diarrhea (CNSD who did not fulfill Rome III criteria for IBS-D. Demographic data, predominant bowel habit pattern, concurrent use of medications, etc., were noted. Results: Patients with IBS-D were 119 (51% with a mean age of 35 ± 13 years, while those with CNSD were 115 (49% with mean age 36 ± 15 years. Patients in both IBS-D and CNSD were comparable in gender, with male 87 (74% and female 77 (64%. SIBO was documented by lactose H 2 BT in 32/234 (14% cases. It was positive in 22/119 (19% cases with IBS-D, while 10/115 (9% cases had CNSD (P = 0.03. LI was positive in 43/234 (18% cases. Of these, 25/119 (21% cases had IBS-D and 18/115 (16% cases had CNSD (P = 0.29. Conclusion: SIBO was seen in a significant number of our patients with IBS-D. There was no significant age or gender difference in patients with or without SIBO.

    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.

    Purpose: To determine whether hyperosmolar and effervescent agents proven individually to accelerate transit time in the barium small bowel examination have an additive effect when combined, surpassing that of either agent alone. Materials and methods: One hundred and forty-nine patients were randomised to four groups. Three hundred milliliters of barium sulphate alone was given to the first group. Fifteen milliliters of iodinated hyperosmolar contrast agent (Gastrografin, meglumine/sodium diatrizoate, Schering) was given in addition to barium sulphate to the second group while six packets of effervescent granules (Carbex, Ferring) were added for the third group. The final group was given a combination of both additives and barium sulphate. The time taken following ingestion for the contrast column to reach the caecum, as assessed by frequent interval fluoroscopy, was recorded. A subgroup of 32 patients were selected randomly from the four groups, 8 from each and assessed for quality of examination. Statistical assessments were made using Kruskal-Wallis and Mann-Whitney tests. Results: One hundred and nineteen patients were analysed after exclusions. The addition of accelerant to barium sulphate, both individually and in combination significantly reduced the small bowel transit time (p < 0.001). No significant difference existed between the additives when used with barium alone. The combined group had significantly faster transit times compared to the hyperosmolar group (p = 0.02). Differences between combined and effervescent groups tended towards significance (p = 0.09). No significant difference existed between groups when examination quality was assessed. Conclusion: These results suggest that the addition of combined effervescent and hyperosmolar agents to the barium suspension may significantly shorten the small bowel transit time without adversely affecting examination quality. This has implications for patient acceptability of the examination as well as potentially reducing screening time and therefore radiation dose.

    Full Text Available AIM: To assess the value of double-balloon enteroscopy (DBE for the diagnosis of gastrointestinal mesenchymal tumors (GIMTs in the small bowel and clarify their clinical and endoscopic characteristics. METHODS: A retrospective review in a total of 783 patients who underwent a DBE procedure from January 2003 to December 2011 was conducted. Data from patients with pathologically confirmed GIMTs were analyzed at a single tertiary center with nine years’ experience. The primary outcomes assessed included characteristics of patients with GIMTs, indications for DBE, overall diagnostic yield of GIMTs, endoscopic morphology, positive biopsy, comparison of diagnosis with capsule endoscopy, and subsequent interventional management. RESULTS: GIMTs were identified and analyzed in 77 patients. The mean age was 47.74 ± 14.14 years (range: 20-77 years, with 63.6% being males. The majority of individuals presented with gastrointestinal bleeding, accounting for 81.8%, followed by abdominal pain, accounting for 10.4%. Small bowel pathologies were found in 71 patients, the detection rate was 92.2%. The diagnostic yield of DBE for GIMTs was 88.3%. DBE was superior to capsule endoscopy in the diagnosis of GIMTs (P = 0.006; McNemar’s ?2 test. Gastrointestinal stromal tumor was the most frequent and leiomyoma was the second frequent GIMT. Single and focal lesions were typical of GIMTs, and masses with smooth or unsmooth surface were the most common in the small bowel. GIMTs were removed from all the patients surgically except one patient treated with endoscopic resection. CONCLUSION: DBE is a safe and valuable procedure for patients with suspected GIMTs, and it provides an accurate position for subsequent surgical intervention.

    Objective To evaluate mucosal healing after 24-month low-dose azathioprine (AZA) treatment in Chinese patients with moderate small bowel Crohn's disease (CD). Methods Patients with lesions mainly located at the ileum were screened by baseline multislice computed tomography enterography and anal-route double-balloon enteroscopy (DBE). They were naive to any immunomodulators and biological agents before the enrollment. Lesions from 150 cm of the terminal ileum proximal to ileocecal valve were assessed by DBE with the simple endoscopic score for CD (SES-CD) after 12 and 24 months of low-dose AZA treatment, respectively. Results The average maximal tolerance dose of AZA was 61.8 ± 17.2 mg/day. The total rates of complete, near-complete, partial and no mucosal healing in 36 patients were 19.4%, 5.6%, 27.8% and 47.2% at month 12 and 30.6%, 25.0%, 33.3% and 11.1% at month 24, respectively. The baseline SES-CD (odds ratio [OR] 2.71, 95% confidence interval [CI] 1.11–6.63, P = 0.029) and duration of disease (OR 1.27, 95% CI 1.10–1.47, P = 0.001) were two relevant factors associated with the mucosal healing of patients with small bowel CD. Conclusion A 24-month low-dose AZA regimen as maintenance treatment in moderate small bowel CD could achieve a higher mucosal healing rate than that of 12-month treatment in Chinese patients, especially in those with duration of disease less than 12 months and a baseline SES-CD of 5 or 6.

    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 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. 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)

  17. 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.)

  18. A rare complication of small bowel intussusception: Report of a case and review of literature

    2013-01-01

    Full Text Available Volvulus and intussusception are rare conditions in children. We describe an unusual case of intussusception due to a solitary Peutz-Jeghers type hamartomatous polyp complicated by volvulus, which occurred in an 11-year-old girl. A laparotomy allows to successfully treat the pathology. The postoperative course was favourable. We discuss the clinical findings and the values of the preoperative instrumental diagnosis. The literature is reviewed. Identifying a midgut volvulus, as complication of a small bowel intussusception, during the diagnostic phase could help in choosing the most appropriate surgical approach.

    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.

    This paper is concerned with the classification of tumoral tissue in the small bowel by using capsule endoscopic images. The followed approach is based on texture classification. Texture descriptors are derived from selected scales of the Discrete Curvelet Transform (DCT). The goal is to take advantage of the high directional sensitivity of the DCT (16 directions) when compared with the Discrete Wavelet Transform (DWT) (3 directions). Second order statistics are then computed in the HSV color space and named Color Curvelet Covariance (3C) coefficients. Finally, these coefficients are modeled by a Gaussian Mixture Model (GMM). Sensitivity of 99% and specificity of 95.19% are obtained in the testing set. PMID:21096477

    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

    2010-01-01

    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.

    Full Text Available Abstract Introduction Small bowel intussusception is rare in adults and accounts for one percent of all bowel obstructions. Malignancy is the etiologic agent in approximately 50 percent of all cases. Case presentation Our first patient was an 80-year-old Caucasian woman with signs and symptoms of intermittent bowel obstruction for the last 12 months. Pre-operative investigation by abdominal computed tomography scanning revealed an obstruction at the ileocecal valve. Exploratory laparotomy revealed an ileocecal intussusception. She underwent an enterectomy. Histological examination showed metastatic breast cancer (lobular carcinoma. Our patient had previously undergone a mastectomy due to carcinoma three years earlier. Our second patient was an 80-year-old Caucasian man with signs and symptoms of acute bowel obstruction. Pre-operative investigation by abdominal computed tomography scanning showed an intussusception in the proximal part of the small bowel. Exploratory laparotomy revealed a jejunojejunal intussusception. He underwent an enterectomy. Histological examination showed metastatic melanoma. Our patient had a prior history of a primary cutaneous melanoma which was excised two years ago. Conclusion Pre-operative determination of the etiologic agent of intussusception in the small bowel in adults is difficult. Although a computed tomography scan is very helpful, the diagnosis of intussusception is made by exploratory laparotomy and histological examination defines the etiologic agent. A prior malignancy in the patient's history must be taken under consideration as a possible cause of intussusception.

    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.

    Congenital mesenteric defects are rare causes of bowel obstruction. Even rarer are mesenteric defects with an apple peel type of deformity, probably described definitively only once previously. We present a case of a 3 year old boy who presented with a septic-like picture of severe metabolic acidosis and lethargy from a bowel obstruction with bowel ischemia. At laparotomy he was found to have bowel infarction due to herniation through a congenital mesenteric defect with an apple peel type of deformity of the bowel without bowel atresia. PMID:23331843

    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.

  8. 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

    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.

    2014-03-14

    Irritable bowel syndrome (IBS) is a common condition characterized by abdominal pain or discomfort, bloating, and altered stool form and passage. Small intestinal bacterial overgrowth (SIBO) is a condition in which there is overgrowth of bacteria in small bowel in excess of 10⁵ colony forming units per milliliter on culture of the upper gut aspirate. Frequency of SIBO varied from 4%-78% among patients with IBS and from 1%-40% among controls. Higher frequency in some studies might be due to fallacious criteria [post-lactulose breath-hydrogen rise 20 PPM above basal within 90 min (early-peak)]. Glucose hydrogen breath test (GHBT) has a low sensitivity to diagnose SIBO. Hence, studies based on GHBT might have under-estimated frequency of SIBO. Therefore, it is important to analyze these studies carefully to evaluate whether the reported association between IBS and SIBO is over or under-projected. This review evaluates studies on association between SIBO and IBS, discordance between different studies, their strength and weakness including methodological issues and evidence on therapeutic manipulation of gut flora on symptoms of IBS.

    Antiphospholipid syndrome is a multi-system disease characterized by the formation of thromboembolic complications and/or pregnancy morbidity, and with persistently increased titers of antiphospholipid antibodies. We report the case of a 50-year-old, previously healthy man who presented with fever and new-onset, dull abdominal pain. A contrast-enhanced computed tomography scan showed segmental small bowel obstruction, for which an emergency laparotomy was performed. Histopathologic examination of resected tissues revealed multiple intestinal and mesenteric thromboses of small vessels. Laboratory tests for serum antiphospholipid (anticardiolipin IgM) and anti-?2-glycoprotein I antibodies were positive. Despite proactive implementation of anticoagulation, steroid, and antibiotic therapies, the patient's condition rapidly deteriorated, and he died 22 d after admission. This case highlights that antiphospholipid syndrome should be suspected in patients with unexplainable ischemic bowel and intestinal necrosis presenting with insidious clinical features that may be secondary to the disease, as early diagnosis is critical to implement timely treatments in order to ameliorate the disease course.

    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)

  14. 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 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.

    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.

    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. PMID:17021699

    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.

  19. 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

    Morgagni hernia is an uncommon presentation representing about 3% in incidence and usually located in the right-sided anterior diaphragm. We experienced a case of Morgagni hernia in a seventy four-year-old male who was admitted complaining of intermittent abdominal pain. The diagnosis was made initially by chest and abdominal radiography, and an incarcerated Morgagni hernia was finally diagnosed with abdominal CT scans. Emergent laparotomy was performed. Morgagni foramen was located on the left-sided anterior diaphragm and Morgagni hernia which contained greater omentum and strangulated small intestine was gently reducted. Morgagni foramen measuring 4 x 5 cm was repaired with a Gortex mesh. We reported the experience of left-sided Morgagni hernia complicating incarcerated small bowel hernia in an old male patient.

  1. The Dose-Volume Relationship of Small Bowel Irradiation and Acute Grade 3 Diarrhea During Chemoradiotherapy for Rectal Cancer

    International Nuclear Information System (INIS)

    Purpose: Previous work has found a highly significant relationship between the irradiated small-bowel volume and development of Grade 3 small-bowel toxicity in patients with rectal cancer. This study tested the previously defined parameters in a much larger group of patients. Methods and Materials: A total of 96 consecutive patients receiving pelvic radiation therapy for rectal cancer had treatment planning computed tomographic scans with small-bowel contrast that allowed the small bowel to be outlined with calculation of a small-bowel dose-volume histogram for the initial intended pelvic treatment to 45 Gy. Patients with at least one parameter above the previously determined dose-volume parameters were considered high risk, whereas those with all parameters below these levels were low risk. The grade of diarrhea and presence of liquid stool was determined prospectively. Results: There was a highly significant association with small-bowel dose-volume and Grade 3 diarrhea (p ? 0.008). The high-risk and low-risk parameters were predictive with Grade 3 diarrhea in 16 of 51 high-risk patients and in 4 of 45 low-risk patients (p = 0.01). Patients who had undergone irradiation preoperatively had a lower incidence of Grade 3 diarrhea than those treated postoperatively (18% vs. 28%; p = 0.31); however, the predictive ability of the high-risk/low-risk parameters was better for preoperatively (p = 0.03) than for postoperatively treated patients (p = 0.15). Revised risk parameters were derived that improved the overall predictive ability (p = 0.004). Conclusions: The highly significant dose-volume relationship and validity of the high-risk and low-risk parameters were confirmed in a large group of patients. The risk parameters provided better modeling for the preoperative patients than for the postoperative patients

    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.

El abordaje laparoscópico ha sido incorporado recientemente, sin embargo, existe información limitada sobre su seguri [...] dad y sus resultados varían considerablemente. 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.

    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.

    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)

    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.

Hay escasas publicaciones nacionales sobre esta técnica en enfermedad diverticular. Objetivo: Presentar nuestra experiencia en enfermedad diverticular en un [...] a serie consecutiva de pacientes con indicación quirúrgica electiva resueltos por vía laparoscópica. Material y Método: Se analizan los protocolos prospectivos de cirugía laparoscópica de colon con diagnóstico de enfermedad diverticular para resolución electiva, desde junio de 1997, hasta diciembre de 2009. Todo paciente con indicación quirúrgica electiva por esta patología fue resuelto por vía laparoscópica. Se estudian edad, sexo, tipo de resección, evolución postoperatoria inmediata y tardía. Resultados: Se operaron 60 pacientes, con edad promedio de 53,8 años. De éstos 46 fueron sigmoidectomías y 14 hemicolectomías izquierdas. El tiempo operatorio promedio fue de 173 minutos y la hospitalización de 4,16 días. Se convirtieron 3 pacientes (5%) y hubo 3 complicaciones (5%), que fueron manejadas médicamente. Hubo 1 estenosis de anastomosis tratada endoscópicamente como complicación tardía. Seguimiento promedio de 37,9 meses. Hubo 2 recidivas (3,3%), tratadas médicamente y no hubo mortalidad en esta serie. Conclusión: La cirugía laparoscópica para la enfermedad diverticular electiva es factible de realizar en la gran mayoría de los pacientes, con baja morbilidad y rápida recuperación. Abstract in english Background: Colorectal colectomy is a less invasive technique that can be used for the treatment of diverticular disease, recently in younger patients. Aim: To report the experience with laparoscopic colectomy for diverticular disease. Material and Methods: All patients with indication for elective [...] surgical resolution for diverticular disease were subjected to laparoscopic surgery from 1997 to 2009. The surgical protocols of these patients were analyzed. Results: Sixty patients with average age 53,8 (31 males) were operated in the period. Forty six were subjected to a sigmoidectomy and 14 to left hemicolectomy. Operative average time was 173 minutes and hospital stay 4,16 days. Three patients had to be converted to open surgery and three had complications that were managed without need of reoperation. During a median follow up of 38 months, the disease relapsed in two patients, which did not require a new intervention. Conclusions: Elective laparoscopic colectomy for diverticular disease is feasible and safe.

    Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT Lymphoma) of the gastrointestinal tract commonly involves the stomach in the setting of concurrent Helicobacter pylori (H. pylori) infection. Primary ileal MALT lymphoma is rare, and has not been associated with a specific infectious disease. We report a case of a 58-year-old man who presented to the emergency department with constipation and abdominal distension, and signs of an obstructing mass on computed tomography scan. A small bowel resection was performed which revealed an 8 cm saccular dilatation with thickened bowel wall and subjacent thickened tan-yellow tissue extending into the mesentery. Histologically, there was a diffuse lymphoid infiltrate consisting of small atypical cells with monocytoid features. These cells were CD20-positive B-lymphocytes that co-expressed BCL-2 and were negative for CD5, CD10, CD43, and cyclin D1 on immunohistochemical studies. Kappa-restricted plasma cells were also identified by in situ hybridization. The overall proliferation index was low with Ki-67 immunoreactivity in approximately 10 % of cells. No areas suspicious for large cell or high grade transformation were identified. The pathologic findings were diagnostic of an extranodal marginal zone lymphoma involving the ileum, with early involvement of mesenteric lymph nodes. Small hypermetabolic right mesenteric and bilateral hilar lymph nodes were identified by imaging. The bone marrow biopsy showed no evidence of involvement by lymphoma. The patient was clinically considered advanced stage and opted for therapy with rituximab infusions. After six months of therapy, follow-up radiologic studies demonstrated significant decrease in size of the mesenteric lymph nodes. PMID:26178711

    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.

  13. 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

    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.

  15. CO2 as a distending medium for gastric and small bowel MRI: a feasibility study

    International Nuclear Information System (INIS)

    This work evaluates carbon dioxide as a contrast medium for magnetic resonance imaging of the stomach and small bowel. Twelve healthy volunteers underwent rapid magnetic resonance imaging after oral administration of a carbon dioxide generating agent using a combination of breath-hold and interactive fluoroscopic imaging during breathing. Diagnostic-quality images were obtained in 100% of cases for the stomach and in 92, 75, 67 and 42% of cases for the duodenal segments 1-4, respectively. Visualisation of the jejunum and ileum proved unacceptable for clinical use and anti-peristaltic agents did not significantly influence the results. Further development of fast imaging and magnetic resonance interactive fluoroscopic methods may allow the use of carbon dioxide as a contrast medium for clinical imaging of the stomach and duodenum.

    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 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.

  19. 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.

    The Essure permanent birth control system (Conceptus Inc, San Carlos, CA) is currently the only Food and Drug Administration-approved hysteroscopic sterilization method and has been widely accepted as a safe and effective procedure. We present a rare case of tubal perforation, coil fragmentation, and distal migration into small and large bowel mesentery 8 days after the insertion of the Essure device. We describe the successful management of this complication using laparoscopy and intraoperative fluoroscopy. Providers using Essure must be aware of the possibility of fragmentation of the Essure coils. Intraoperative imaging, ideally fluoroscopy, should be strongly considered in the management of Essure migration to ensure localization and full retrieval of Essure material. PMID:25460518

    2010-08-01

    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.

  3. Towards a less costly but accurate test of gastric emptying and small bowel transit

    International Nuclear Information System (INIS)

    Our aim is to develop a less costly but accurate test of stomach emptying and small bowel transit by utilizing selected scintigraphic observations 1-6 hr after ingestion of a radiolabeled solid meal. These selected data were compared with more detailed analyses that require multiple scans and labor-intensive technical support. A logistic discriminant analysis was used to estimate the sensitivity and specificity of selected summaries of scintigraphic transit measurements. We studied 14 patients with motility disorders (eight neuropathic and six myopathic, confirmed by standard gastrointestinal manometry) and 37 healthy subjects. The patient group had abnormal gastric emptying (GE) and small bowel transit time (SBTT). The proportion of radiolabel retained in the stomach from 2 to 4 hr (GE 2 hr, GE 3 hr, GE 4 hr), as well as the proportion filling the colon at 4 and 6 hr (CF 4 hr, CF 6 hr) were individually able to differentiate health from disease (P less than 0.05 for each). From the logistic discriminant model, an estimated sensitivity of 93% resulted in similar specificities for detailed and selected transit parameters for gastric emptying (range: 62-70%). Similarly, combining selected observations, such as GE 4 hr with CF 6 hr, had a specificity of 76%, which was similar to the specificity of combinations of more detailed analyses. Based on the present studies and future confirmation in a larger number of patients, including those with less severe motility disorders, the 2-, 4-, and 6-hr scans with quantitation of proportions of counts in stomach and colon should provide a useful, relatively inexpensive strategy to identify and monitor motility disorders in clinical and epidemiologic studies

    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.

  7. Value of CT findings to predict surgical ischemia in small bowel obstruction: A systematic review and meta-analysis

    International Nuclear Information System (INIS)

    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.

  10. Small intestinal bacterial overgrowth in irritable bowel syndrome: are there any predictors?

    Directory of Open Access Journals (Sweden)

    McCallum Richard W

    2010-02-01

    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.

  14. Arterial hypertension due to fructose ingestion: model based on intermittent osmotic fluid trapping in the small bowel

    Full Text Available Abstract Based on recently reported data that fructose ingestion is linked to arterial hypertension, a model of regulatory loops involving the colon role in maintenance of fluid and sodium homeostasis is proposed. In normal digestion of hyperosmolar fluids, also in cases of postprandial hypotension and in patients having the "dumping" syndrome after gastric surgery, any hyperosmolar intestinal content is diluted by water taken from circulation and being trapped in the bowel until reabsorption. High fructose corn sirup (HFCS soft drinks are among common hyperosmolar drinks. Fructose is slowly absorbed through passive carrier-mediated facilitated diffusion, along the entire small bowel, thus preventing absorption of the trapped water for several hours. Here presented interpretation is that ingestion of hyperosmolar HFCS drinks due to a transient fluid shift into the small bowel increases renin secretion and sympathetic activity, leading to rise in ADH and aldosterone secretions. Their actions spare water and sodium in the large bowel and kidneys. Alteration of colon absorption due to hormone exposure depends on cell renewal and takes days to develop, so the momentary capacity of sodium absorption in the colon depends on the average aldosterone and ADH exposure during few previous days. This inertia in modulation of the colon function can make an individual that often takes HFCS drinks prone to sodium retention, until a new balance is reached with an expanded ECF pool and arterial hypertension. In individuals with impaired fructose absorption, even a higher risk of arterial hypertension can be expected.

    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

  17. The volume effect in radiation-related late small bowel complications. Results of a clinical study of the EORTC Radiotherapy Cooperative Group in patients treated for rectal carcinoma

    International Nuclear Information System (INIS)

    The purpose of this study was to quantify the correlation between irradiated small bowel volume and late occurring small bowel complications. Methods: Small bowel volumes in the high-dose region were measured using orthogonal barium films for 203 patients treated for rectal carcinoma with pelvic postoperative radiotherapy to 50 Gy in an EORTC multicentric study. Results: The 5-year estimate of lat pelvic small bowel obstruction requiring surgery was 11%. No correlation between the irradiated small bowel volume and obstruction was detected. The actuarial 5-year estimate of chronic diarrhea varied from 31% in patients with irradiated small bowel volumes below 77 cm3 to 42% in patients with volumes over 328 cm3. This correlation was significant in the univariate and multivariate analysis (p=0.025). The type of rectal surgery significantly influenced the incidence of chronic diarrhea and malabsorption, the actuarial 5-year estimate being 49% and 26% after low anterior resection and abdominoperineal resection, respectively (p=0.04). Conclusions: This study demonstrated that there is a volume-effect in radiation-induced diarrhea atr a dose of 50 Gy in 25 fractions. No volume-effect for small bowel obstruction was detected at this dose-level in pelvic postoperative radiotherapy. A review of the literature data on small bowel obstruction indicates that the volume effect at this dose level can only be demonstrated in patients who were treated with extended field radiotherapy (estimated small bowel volume 800 cm3) after intra-abdominal surgery.

    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.

    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)

    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.)

  2. 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.

  3. 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.)

    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.

  5. Is laparoscopy equal to laparotomy in detecting and treating small bowel injuries in a porcine model?

    Full Text Available AIM: To evaluate the safety and effectiveness of laparoscopy compared with laparotomy for diagnosing and treating small bowel injuries (SBIs in a porcine model. METHODS: Twenty-eight female pigs were anesthetized and laid in the left recumbent position. The SBI model was established by shooting at the right lower quadrant of the abdomen. The pigs were then randomized into either the laparotomy group or the laparoscopy group. All pigs underwent routine exploratory laparotomy or laparoscopy to evaluate the abdominal injuries, particularly the types, sites, and numbers of SBIs. Traditional open surgery or therapeutic laparoscopy was then performed. All pigs were kept alive within the observational period (postoperative 72 h. The postoperative recovery of each pig was carefully observed. RESULTS: The vital signs of all pigs were stable within 1-2 h after shooting and none of the pigs died from gunshot wounds or SBIs immediately. The SBI model was successfully established in all pigs and definitively diagnosed with single or multiple SBIs either by exploratory laparotomy or laparoscopy. Compared with exploratory laparotomy, laparoscopy took a significantly longer time for diagnosis (41.27 ± 12.04 min vs 27.64 ± 13.32 min, P = 0.02, but the time for therapeutic laparoscopy was similar to that of open surgery. The length of incision was significantly reduced in the laparoscopy group compared with the laparotomy group (5.27 ± 1.86 cm vs 15.73 ± 1.06 cm, P < 0.01. In the final post-mortem examination 72 h after surgery, both laparotomy and laparoscopy offered a definitive diagnosis with no missed injuries. Postoperative complications occurred in four cases (three following laparotomy and one following laparoscopy, P = 0.326. The average recovery period for bowel function, vital appearance, and food re-intake after laparoscopy was 10.36 ± 4.72 h, 14.91 ± 3.14 h, and 15.00 ± 7.11 h, respectively. All of these were significantly shorter than after laparotomy (21.27 ± 10.17 h, P = 0.004; 27.82 ± 9.61 h, P < 0.001; and 24.55 ± 9.72 h, respectively, P = 0.016. CONCLUSION: Compared with laparotomy, laparoscopy offers equivalent efficacy for diagnosing and treating SBIs, and reduces postoperative complications as well as recovery period.

  6. Comparison of upper gastrointestinal radiographic findings to histopathologic observations: a retrospective study of 41 dogs and cats with suspected small bowel infiltrative disease (1985 to 1990)

    International Nuclear Information System (INIS)

    It was the intent of this study to define which, if any, radiographic observations corresponded with specific causes of diffuse infiltrative small bowel disease and if radiographic findings could differentiate inflammatory disease from neoplastic disease and either of them from normal. Bowel spasticity, luminal narrowing, and thumb printing tend to indicate the presence of tumor more often than inflammatory disease. Increased bowel gas in cats and barium adhesion in dogs and cats suggest that a component of enteritis is present. Decreased bowel gas in dogs is more often associated with obstructive disease, but is not helpful in differentiating diffuse inflammatory disease from diffuse neoplastic disease. While several observations that can foster differentiation of neoplastic from inflammatory disease were found, this study also indicated that the UGI lacks a high degree of predictive value other than to indicate the presence of infiltrative small bowel disease

    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 Introduction. Endometriosis is defined as the presence of benign endometrial glands and stroma outside the normal anatomical location. Endometriosis of the small bowel, especially symptomatic small bowel involvement, is very unusual. Case report. We presented a 45-year-old woman with acute intestinal obstruction due to ileal endometriosis The patient complained of severe abdominal pain, nausea and vomitting. Immediate laparotomy was carried out. Above the ileocecal valve there was an ulcerated, edematous and fragile segmental lesion that caused intestinal obstruction. Histology of this ileal segment revealed endometriosis and an annular stricture that again showed foci of endometriosis. Conclusion. In reproductiveage women with the symptoms of intestinal obstruction, intestinal endometriosis should be kept in mind.

    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 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.

    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 mode...

    Introduction Small intestinal bacterial overgrowth (SIBO) occurs in varying frequency in irritable bowel syndrome (IBS). We studied the frequency of SIBO in IBS and chronic non-specific diarrhea (CNSD). Methods 129 patients with IBS (Manning's criteria), 73 with CNSD (≥ 4 weeks diarrhea with two of these tests normal [urine D-xylose, fecal fat and duodenal biopsy]) and 51 healthy controls (HC) were evaluated for SIBO using glucose hydrogen breath test (GHBT).

  16. 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.

  17. Acute Small Bowel Hemorrhage in Three Patients with End-Stage Renal Disease: Diagnosis and Management by Angiographic Intervention

    International Nuclear Information System (INIS)

    Three patients who had undergone hemodialysis for end-stage renal disease, presented with acute small bowel hemorrhage,and were treated with superselective transcatheter arterial embolization via coaxial microcatheters. In all patients pre-procedure upper gastrointestinal (GI) endoscopy and colonoscopy had failed to demonstrate the source of the hemorrhage. Selective diagnostic angiography revealed frank extravasations of contrast from the small bowel arteries (one jejunal artery and two ileal arteries). After superselection of feeding arteries with a microcatheter, transcatheter embolization using Gelfoam and microcoils was performed in all three patients. Immediate hemostasis was achieved in all patients and the patients were discharged free from symptoms 3-5 days after embolization. No evidence of intestinal ischemia or infarction was noted, with the time from procedure to last follow-up ranging from 4 to 12 months. We conclude that superselective angiography is a valuable tool for diagnosing and treating acute small bowel hemorrhage inpatients with end-stage renal disease when endoscopic evaluation has failed

    Our study aimed to assess the diagnostic utility of magnetic resonance enterography (MRE) compared to capsule endoscopy (CE) for the detection of small bowel polyps in patients with Peutz-Jeghers syndrome (PJS); with findings verified by balloon enteroscopy (BE). Adult patients were prospectively recruited across two tertiary centres and underwent MRE followed by CE, with a subsequent BE performed in patients with significant (?10 mm) polyps. The primary endpoint was the total number of significant (?10 mm) small bowel polyps detected. The number of patients with at least one significant polyp, correlation with BE findings, and patients' preferences were secondary endpoints. A total of 20 patients (7 male; mean age 34.9 years) underwent both investigations. The number of polyps ?10 mm detected by CE was greater than by MRE (47 vs 14 polyps, P = 0.02). The number of patients with at least one significant polyp identified by CE was 11 (55 %) compared with 7 (35 %) identified by MRE (P = 0.25). Subsequent BE in 12 patients identified a total of 26 significant polyps in 8 patients. The positive predictive value of finding a polyp at BE was higher for MRE (100 %) compared to CE (60 %). Overall patient preferences identified CE as the preferred modality. This prospective study demonstrated that CE identifies significantly more small bowel polyps compared with MRE in patients with PJS. Correlation between the two techniques and subsequent BE however was relatively poor. PMID:24509884

    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.

  20. 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)

  1. 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

  2. Bowel disease after radiotherapy

    International Nuclear Information System (INIS)

    The clinical presentation, operative findings and outcome in 40 patients who required surgery for bowel disease after radiotherapy are presented. The type of presentation varied according to the time after radiotherapy. In the first month, many patients had a proctitis but none required surgery. Five patients were operated on within one month, 2 for radiation-induced acute ileitis and 3 for exacerbations of pre-existing disease (diverticular disease 2, ulcerative colitis 1). The commonest time of presentation was between 3 and 18 months after radiotherapy, when 20 patients needed surgery for bowel disease caused by radiation-induced local ischaemia. Twelve of these patients had chronic perforation, 6 had severe rectal bleeding and 2 had painful anorectal ulceration. Fifteen patients presented between 2 and 24 years after radiotherapy, usually with incomplete intestinal obstruction due to a fibrous stricture, but 2 patients had rectal carcinoma. Wide resection of the involved bowel was the principal method of treatment but any anastomosis was protected by a proximal defunctioning stoma. There was no operative mortality but 10 patients have died subsequently. The danger of dismissing these patients as having incurable malignancy is stressed because, although the condition is infrequent, it is usually amenable to adequate surgery. (author)

    Full Text Available Abstract Background We sought to evaluate prognostic factors affecting overall survival (OS, and to investigate the role of palliative chemotherapy using propensity score-based weighting, in patients with advanced small bowel adenocarcinoma (SBA. Methods Data from a total of 91 patients diagnosed with advanced SBA at the Asan Medical Center between January 1989 and December 2009 were retrospectively analyzed. Patients were split into two groups, those who did and did not receive palliative chemotherapy. Results Overall, 81 patients (89.0% died, at a median survival time of 6.6 months (95% confidence interval [CI], 5.5 - 7.5 months. The 40 patients receiving chemotherapy showed overall response and disease control rates of 11.1% and 37.0%, respectively, with OS and progression-free survival (PFS of 11.8 months (95% CI, 4.6 - 19.0 months and 5.7 months (95% CI, 3.5 - 8.0 months, respectively. The 41 patients who did not receive chemotherapy had an OS of 4.1 months (95% CI, 3.1 - 5.1 months and a PFS of 1.3 months (95% CI, 0.8 - 1.7 months. Multivariate analysis showed that lack of tumor resection, non-prescription of chemotherapy, liver metastasis, and intra-abdominal lymph node metastasis, were all independently associated with poor survival outcomes. After inverse probability of treatment weighting (IPTW adjustment, the group that did not receive chemotherapy was at a significantly higher risk of mortality (HR 3.44, 95% CI 2.03 - 5.83, p Conclusion Palliative chemotherapy may improve survival outcomes in patients with advanced SBA.

    Small bowel (SB) is an organ at risk (OAR) that may potentially develop toxicity after radiotherapy for cervix cancer. However, its dose from brachytherapy (BT) is not systematically reported as in other OARs, even with image-guided brachytherapy (IGBT). This study aims to introduce consideration of quantified objectives for SB in BT plan optimization and to evaluate the feasibility of sparing SB while maintaining adequate target coverage. In all, 13 patients were included in this retrospective study. All patients were treated with external beam radiotherapy (EBRT) 45Gy in 25 fractions followed by high dose rate (HDR)-BT boost of 28Gy in 4 fractions using tandem/ring applicator. Magnetic resonance imaging (MRI) and computed tomographic (CT) images were obtained to define the gross tumor volume (GTV), high-risk clinical target volume (HR-CTV) and OARs (rectum, bladder, sigmoid colon, and SB). Treatment plans were generated for each patient using GEC-ESTRO recommendations based on the first CT/MRI. Treatment plans were revised to reduce SB dose when the [Formula: see text] dose to SB was > 5Gy, while maintaining other OAR constraints. For the 7 patients with 2 sets of CT and MRI studies, the interfraction variation of the most exposed SB was analyzed. Plan revisions were done in 6 of 13 cases owing to high [Formula: see text] of SB. An average reduction of 19% in [Formula: see text] was achieved. Meeting SB and other OAR constraints resulted in less than optimal target coverage in 2 patients (D90 of HR-CTV < 77Gy??10). The highest interfraction variation was observed for SB at 16 ± 59%, as opposed to 28 ± 27% for rectum and 21 ± 16% for bladder. Prospective reporting of SB dose could provide data required to establish a potential correlation with radiation-induced late complication for SB. PMID:26235549

    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.

    In bowel ischemia, impaired mucosal integrity may allow intestinal pancreatic enzyme products to become systemic and precipitate irreversible shock and death. This can be attenuated by pancreatic enzyme inhibition in the small bowel lumen. It is unresolved, however, whether ischemically-mediated mucosal disruption is the key event allowing pancreatic enzyme products systemic access, and whether intestinal digestive enzyme activity in concert with increased mucosal permeability leads to shock in the absence of ischemia. To test this possibility, the small intestinal lumen of non-ischemic rats was perfused for two hours with either digestive enzymes, a mucin disruption strategy (i.e., mucolytics) designed to increase mucosal permeability, or both, and animals were observed for shock. Digestive enzymes perfused included trypsin, chymotrypsin, elastase, amylase and lipase. Control (n=6) and experimental animals perfused with pancreatic enzymes only (n=6) or single enzymes (n=3 for each of the five enzyme groups) maintained stable hemodynamics. After mucin disruption using a combination of enteral N-acetylcysteine, atropine, and increased flow rates, rats (n=6) developed mild hypotension (pshock and increase systemic protease activation in the absence of ischemia, implicating bowel mucin disruption as a key event in early ischemia. Digestive enzymes and their products, if allowed to penetrate the gut wall may trigger multiorgan failure and death. PMID:22576000

  11. 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

    2012-03-01

    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 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 University 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

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

  15. Differentiation between active and chronic Crohn's disease using MRI small-bowel motility examinations — Initial experience

    International Nuclear Information System (INIS)

    Aim: To evaluate the influence of locally active Crohn's disease on systemic small-bowel motility in patients with chronic Crohn's disease compared to healthy individuals. Material and methods: Fifteen healthy individuals (11 men, four women; mean age 37 years) and 20 patients with histopathologically proven active (n = 15; 10 women, 5 men; mean age 45 years) or chronic (n = 5; four women, one man; mean age 48 years) Crohn's disease were included in this institutional review board-approved, retrospective study. Magnetic resonance imaging (MRI; 1.5 T) was performed after standardized preparation. Two-dimensional (2D) cine sequences for motility acquisition were performed in apnoea (27 s). Motility assessment was performed using dedicated software in three randomly chosen areas of the small-bowel outside known Crohn's disease-affected hotspots. The main quantitative characteristics (frequency, amplitude, occlusion rate) were compared using Student's t-test and one-way analysis of variance (ANOVA). Results: Three randomly chosen segments were analysed in each participant. Patients with active Crohn's disease had significantly (p < 0.05) reduced contraction frequencies (active Crohn's disease: 2.86/min; chronic: 4.14/min; healthy: 4.53/min) and luminal occlusion rates (active: 0.43; chronic: 0.70; healthy: 0.73) compared to healthy individuals and patients with chronic Crohn's disease. Contraction amplitudes were significantly reduced during active Crohn's disease (6.71 mm) compared to healthy participants (10.14 mm), but this only reached borderline significance in comparison to chronic Crohn's disease (8.87 mm). Mean bowel lumen diameter was significantly (p = 0.04) higher in patients with active Crohn's disease (16.91 mm) compared to healthy participants (14.79 mm) but not in comparison to patients with chronic Crohn's disease (13.68). Conclusion: The findings of the present study suggest that local inflammatory activity of small-bowel segments in patients with active Crohn's disease alters small-bowel motility in distant, non-affected segments. The motility patterns revealed reduced contraction-wave frequencies, amplitudes, and decreased luminal occlusion rates. Thus evaluation of these characteristics potentially helps to differentiate between chronic and active Crohn's disease

    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.

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.

  18. Small bowel video capsule endoscopy in Crohn’s disease: What have we learned in the last ten years?

    2011-02-01

    Full Text Available Since its introduction in 2001, capsule endoscopy (CE has become the most important advance in the study of small bowel disease, including Crohn’s disease (CD. This technique has been demonstrated to be superior to all other current forms of radiological investigation in detecting mucosal abnormalities of small bowel nonstricturing CD. CE has proven to be extremely useful in diagnosing CD in patients with inconclusive findings from ileocolonoscopy and x-ray-based studies. Almost half of all patients with CD involving the ileum also present lesions in proximal intestinal segments, with the small bowel being exclusively involved in up to 30% of all CD cases. Despite the widespread use of CE, several questions concerning the utility of this technique remain unanswered. The lack of commonly agreed diagnostic criteria for defining CD lesions with the aid of CE may have had an influence on the variation in diagnostic results for CE reported in the literature. The utility of CE in monitoring CD and in guiding therapy has also been proposed. Furthermore, CE could be a useful second-line technique for patients with an established diagnosis of CD and unexplained symptoms. Finally, as no threshold for CD diagnosis has been agreed upon, a severity scale of mucosal disease activity has not been universally followed. None of the available activity indexes based on CE findings has been independently validated. This article discusses several cutting-edge aspects of the usefulness of CE in CD 10 years after its introduction as a sensible method to study the small intestine.

    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%)

    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.)

    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

  5. Post-radiation injury of the ileal small bowel: clinical and pathological report of 12 cases

    International Nuclear Information System (INIS)

    At the Institut Gustave-Roussy we have collected a series of 12 cases studied both on clinical and pathological grounds. These patients underwent ileal resection for acute abdominal symptoms occuring after radiation therapy for genital cancer. Ileal lesions after radiation of gynecological cancer are rare: one per cent at the Institut Gustave-Roussy. These complications occur when certain technical types of radiation therapy are employed, and especially when dose exceeds 50 Gy or when a particular clinical condition is present. Gross examination of the bowel segment shows a stiffness of the digestive wall frequent stenosis, sometimes in assocciation with perforation or fistula. Histological lesions of radiated bowel are essentially located in the submucosa. They are non specific, mainly represented by obliterative angiopathy and fibrosis of the ileal wall

    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.

  8. 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.

    During video capsule endoscopy (VCE), several factors, such as air bubbles, food material in the small bowel, and delayed gastric and small bowel transit time, influence diagnostic yield, small bowel visualization quality, and cecal completion rate. Therefore, bowel preparation before VCE is as essential as bowel preparation before colonoscopy. To date, there have been many comparative studies, consensus, and guidelines regarding different kinds of bowel cleansing agents in bowel preparation for small bowel VCE. Presently, polyethylene glycol- (PEG-) based regimens are given primary recommendation. Sodium picosulphate-based regimens are secondarily recommended, as their cleansing efficacy is less than that of PEG-based regimens. Sodium phosphate as well as complementary simethicone and prokinetics use are considered. In this paper, we reviewed previous studies regarding bowel preparation for small bowel VCE and suggested optimal bowel preparation of VCE. PMID:26880894

  11. 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

    Full Text Available AIM: To determine if there were any interactions between cardiac devices and small bowel capsules secondary to electromagnetic interference (EMI in patients who have undergone small bowel capsule endoscopy (SBCE. METHODS: Authors conducted a chart review of 20 patients with a cardiac pacemaker (CP or implantable cardioverter defibrillator (ICD who underwent continuous electrocardiographic monitoring during their SBCE from 2003-2008. authors searched for unexplained electrocardiogram (ECG findings, changes in CP and ICD set parameters, any abnormality in transmitted capsule data, and adverse clinical events. RESULTS: There were no adverse events or hemodynamically significant arrhythmias reported. CP and ICD set parameters were preserved. The majority of ECG abnormalities were also found in pre- or post- SBCE ECG tracings and the CP behavior during arrhythmias appeared appropriate. Two patients seemed to have episodes of undersensing by the CP. However, similar findings were documented in ECGs taken outside the time frame of the SBCE. One patient was observed to have a low signal encountered from the capsule resulting in lack of localization, but no images were lost. CONCLUSION: Capsule-induced EMI remains a possibility but is unlikely to be clinically important. CP-induced interference of SBCE is also possible, but is infrequent and does not result in loss of images transmitted by the capsule.

  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.)

    The effects of iohexol, sodium diatrizoate and physiologic saline on intestinal distension and circulation were observed for 8 h in nine minipigs with closed-loop obstruction of the small bowel. The two contrast media led to an elevation of intraluminal pressures when initially instilled at pressures above 35 mm Hg. These elevated pressures were not high enough to cause rupture of the bowel wall. Both contrast media caused severe mucosal ischaemia as judged from histologic sections, loops containing sodium diatrizoate more so than iohexol. The blood circulation of the bowel wall, examined by laser Doppler flowmetry, was after 6 to 8 h reduced to about 10% of the values of non-obstructed bowel at intraluminal pressures of about 70 mm Hg in the loops with iohexol and sodium diatrizoate. The correlation to osmolality was obvious when compared with concurrent observations in the loops with physiologic saline. In the bowel loops filled with physiologic saline, the pressure fell to 5 mm Hg after 8 h, regaining approximately one-third of pre-instillation levels of blood flow. On microscopy these bowel loops had a nearly normal mucosa.

    Obstruction caused by strangulation internal hernia secondary to incarceration within the falciform ligament, although rare, has been previously reported in the literature. These cases, however, were unrelated to trauma. We report on the first case in the pediatric literature of a strangulated internal hernia secondary to incarceration in the falciform ligament precipitated by blunt abdominal trauma. A 12-year-old girl presented to the emergency room less than 24 hours after sustaining a kick to the right upper quadrant. She described sharp, nonradiating, right-upper-quadrant abdominal pain, which was associated with nausea and vomiting. A KUB (kidney, ureter, bladder) view showed a paucity of bowel in the right upper quadrant with distended adjacent bowel. An ultrasound showed a small amount of abdominal ascites and a prominent liver. Computed tomography scan revealed a linear hypodensity at the tip of the right lobe of the liver, suggestive of a laceration. Moderate abdominal and pelvic ascites and multiple collapsed small-bowel loops with diffuse wall thickening and poor enhancement were seen in the right upper quadrant. Significantly, pneumatosis was noted, raising the question of obstruction/volvulus and/or bowel ischemia. An exploratory laparotomy revealed incarcerated small bowel herniated into a defect in the falciform ligament, which was resected. The defect was repaired. Seemingly trivial trauma may play a precipitating role in strangulation in a patient who already has a defect in the falciform ligament. PMID:20531130

    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)

    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.

    Objective: We aimed to demonstrate the effect of continuous or bolus nasogastric feeding on gastric emptying, small bowel water content, and splanchnic blood flow measured by magnetic resonance imaging (MRI) in the context of changes in plasma gastrointestinal hormone secretion. Background: Nasogastric/nasoenteral tube feeding is often complicated by diarrhea but the contribution of feeding strategy to the etiology is unclear. Methods: Twelve healthy adult male participants who underwent nasogastric intubation before a baseline MRI scan, received 400?mL of Resource Energy (Nestle) as a bolus over 5 minutes or continuously over 4?hours via pump in this randomized crossover study. Changes in gastric volume, small bowel water content, and superior mesenteric artery blood flow and velocity were measured over 4?hours using MRI and blood glucose and plasma concentrations of insulin, peptide YY, and ghrelin were assayed every 30 minutes. Results: Bolus nasogastric feeding led to significant elevations in gastric volume (P?insulin (P?=?0.0024) and peptide YY (P?small bowel water content, thus fluid flux within the small bowel is not a major contributor to the etiology of tube feeding-related diarrhea.

    In addition to its role in absorbing nutrients, the intestinal mucosa provides an important barrier against toxins and bacteria in the bowel lumen. The present study evaluated gut barrier function following orthotopic (in continuity) intestinal grafting in rats. Graft histology, intestinal permeability, and bacterial translocation to the grafted mesenteric lymph nodes, the host's liver, and the host's spleen were assessed on the 3rd, 5th, and 7th postoperative days. The study group received no immunosuppression after allotransplantation. The two control groups included rats with isografts and rats with cyclosporine-treated allografts. On the 7th POD, the study animals had moderate transmural inflammation due to rejection, with normal histology in the isografts and CsA-treated allografts; increased intestinal permeability, measured by urinary excretion of oral 51Cr-EDTA (P less than 0.01); and increased number of bacteria in the MLN and spleen (P less than 0.05). The number of bacteria in the MLN and spleen of the study group positively correlated with the changes in intestinal permeability (P less than 0.05). Rejection of the orthotopic intestinal graft leads to increased intestinal permeability and bacterial translocation from the lumen of the graft to the host's reticuloendothelial system. Measures to improve gut barrier function and antibiotic therapy during rejection episodes may help reduce the incidence of septic complications after intestinal grafting.

    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.

  9. 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

  10. Open table-top device positioning technique to reduce small bowel obstruction. Positioning accuracy and impact on conformal radiation therapy techniques

    International Nuclear Information System (INIS)

    The immobilization error of patients positioned on the opern table-top device in prone prosition as well as the movement of the small bowel out of the pelvis by this positioning technique was determined. The positioning error is of special importance for the 3-dimensional treatment planning for conformal radiotherapy. The positioning error was determined by superposing 106 portal films with the corresponding simultor films from 21 patients with carcinoma of the rectum who received 3D-planned conformal radiotherapy (o-field technique with irregular blocks). The movement of the small bowel out of the pelvis was studied by comparing simulator films after barium swallow in supine and open table-top position as well with 3D-treatment plans of the same patient in both positions in 3 cases. The positioning error along the medio-lateral, dorso-ventral und cranio-caudal axis was 1.4/-0.6/1.8 mm and the standard deviation 4.4/6.8/6.3 mm, respectively. In comparison to the supine position more rotation errors in the sagittal view were observed (37% and 9% respectively) with a media of 5.1 . Six out of 22 patients showed no adhesions of the small bowel and a complete movement out of the tratment field was achieved. 14 out of 16 Patients with adhesions revealed a partial movement of the small bowel out of the treatment field. Comparing 3D-treatment plans in both positions again demonstrated a marked reduction of the irradiated small bowel volume with the use of the open table-top decive. (orig.)

  11. 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

    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.

  17. 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.)

  18. The effect on the small bowel of 5-FU and oxaliplatin in combination with radiation using a microcolony survival assay

    International Nuclear Information System (INIS)

    In locally advanced rectal cancer, 5-Fluorouracil (5-FU)-based chemoradiation is the standard treatment. The main acute toxicity of this treatment is enteritis. Due to its potential radiosensitizing properties, oxaliplatin has recently been incorporated in many clinical chemoradiation protocols. The aim of this study was to investigate to what extent 5-FU and oxaliplatin influence the radiation (RT) induced small bowel mucosal damage when given in conjunction with single or split dose RT. Immune competent balb-c mice were treated with varying doses of 5-FU, oxaliplatin (given intraperitoneally) and total body RT, alone or in different combinations in a series of experiments. The small bowel damage was studied by a microcolony survival assay. The treatment effect was evaluated using the inverse of the slope (D0) of the exponential part of the dose-response curve. In two separate experiments the dose-response relations were determined for single doses of RT alone, yielding D0 values of 2.79 Gy (95% CI: 2.65 - 2.95) and 2.98 Gy (2.66 - 3.39), for doses in the intervals of 5-17 Gy and 5-10 Gy, respectively. Equitoxic low doses (IC5) of the two drugs in combination with RT caused a decrease in jejunal crypt count with significantly lower D0: 2.30 Gy (2.10 - 2.56) for RT+5-FU and 2.27 Gy (2.08 - 2.49) for RT+oxaliplatin. Adding both drugs to RT did not further decrease D0: 2.28 Gy (1.97 - 2.71) for RT+5-FU+oxaliplatin. A clearly higher crypt survival was noted for split course radiation (3 × 2.5 Gy) compared to a single fraction of 7.5 Gy. The same difference was seen when 5-FU and/or oxaliplatin were added. Combining 5-FU or oxaliplatin with RT lead to an increase in mucosal damage as compared to RT alone in our experimental setting. No additional reduction of jejunal crypt counts was noted when both drugs were combined with single dose RT. The higher crypt survival with split dose radiation indicates a substantial recovery between radiation fractions. This mucosal-sparing effect achieved by fractionation was maintained also when chemotherapy was added

    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.

  2. 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

  3. Total orthotopic allogeneic small bowel transplantation in rats: effect of allograft irradiation combined with cyclosporine-A therapy

    International Nuclear Information System (INIS)

    Cyclosporine treatment of the recipient and irradiation of the donor were used to circumvent rejection and graft versus host disease in the WAG to brown Norway rat model. Irradiation of the donor with five or 10 Gy did prevent graft versus host disease but resulted in more vigorous rejection of small bowel allografts in untreated recipients (mean (SEM) survival time of 11.5 (0.4) (n=8) and 7.5 (0.9) (n=11) days respectively, versus 16.6 (2.6) days (n=17), p''less than''0.01). Cyclosporine treatment of the recipient led to a mean (SEM) survival time of 38.3 (8.5) days (n=10); 20% of the animals developed graft versus host disease. Combined with 5 Gy donor pretreatment, a similar survival was obtained without occurrence of graft versus host disease. However, cyclosporine treatment combined with 10 Gy led to a significant shortening of graft survival (23.1 (6.8) days, n=9). (author)

  4. Acute changes in canine small bowel muscle prostaglandin synthesis and function after x-irradiation with 9.38 Gy

    International Nuclear Information System (INIS)

    Abdominal radiotherapy is often limited by radiation-induced enteritis. Prostaglandin (PG) synthesis may play a role in the altered function of small bowel (SB) muscle and mucosa. Therefore, the authors have investigated the effects of X-radiation on PG synthesis, and other aspects of canine SB smooth muscle function. Canine SB received 9.38 Gy of 250 kVp X-radiation in situ. Electrodes were used to monitor spike burst and propagation of electrical activity in the SB muscle pre- and post-exposure. Animals were sacrificed prior to irradiation and at 1 and 4 days post-irradiation. Serum PG levels were assayed from mesenteric artery and vein samples, and SB muscle was removed for analysis of PG synthesis. SB muscle myoelectric activity decreased after irradiation until sacrifice (day 4). The PG synthesis in irradiated SB muscle at days 1 and 4 increased in PGE/sub 2/ and PGF/sub 2/? and in thromboxane A/sub 2/ metabolite, while the PGI/sub 2/ metabolite decreased. PG levels in venous blood indicate similar changes after passage through the intestine. Although causality is not established, radiation does induce changes in PG synthesis which correlate with changes in myoelectric activity (motility)

A macroscopic score was used to quantify intestinal lesions and intestinal permeability was measured using [51Cr]-ethylenediaminetetraacetic acid ([51Cr]-EDTA). The extent of intestinal lesion, indicated by a macroscopic score, was significantly lower when rofecoxib was administered compared to indomethacin (rofecoxib = 0.0 vs indomethacin = 63.6 ± 25.9; P

    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.

    Vieira, Pedro M; Ramos, Jaime; Lima, Carlos S

    2015-08-01

    This paper addresses the problem of automatic detection of tumoral frames in endoscopic capsule videos by using features directly extracted from the color space. We show that tumor can be appropriately discriminated from normal tissue by using only color information histogram measures from the Lab color space and that light saturated regions are usually classified as tumoral regions when color based discriminative procedures are used. These regions are correctly classified if lightening is discarded becoming the tissue classifier based only on the color differences a and b of the Lab color space. While current state of the art systems for small bowel tumor detection usually rely on the processing of the whole frame regarding features extraction this paper proposes the use of fully automatic segmentation in order to select regions likely to contain tumoral tissue. Classification is performed by using Support Vector Machine (SVM) and Multilayer Perceptron (MLP) by using features from color channels a and b of the Lab color space. The proposed algorithm outperforms in more than 5% a series of other algorithms based on features obtained from the higher frequency components selected from Wavelets and Curvelets transforms while saving important computational resources. In a matter of fact the proposed algorithm is more than 25 times faster than algorithms requiring wavelet/curvelet and co-occurrence computations. PMID:26736929

  9. Radiologic contribution to the extracorporeal lithotripsy treatment of calyceal diverticular calculi

    International Nuclear Information System (INIS)

    The authors reviewed the radiologic studies in 19 patients with calyceal diverticular calculi treated with extracorporeal lithotripsy (EL) in order to establish criteria predicting successful outcome. Pre-EL imaging was performed to evaluate the size of calculus in relation to the diverticular cavity, and the width of the connection of the diverticulum to the adjacent calyx. Post-EL studies were performed to assess fragmentation and passage of fragments. EL fragmented calculi in 15 diverticula with cavities larger than stone volume. Complete passage of fragments was shown in five patients and partial passage in two, all with wide diverticular necks. No passage was seen in eight diverticular with fragmented calculi, five of which had narrow or nondemonstrable necks. The radiologic demonstration of large diverticular correlates well with effective EL fragmentation, and a wide neck results in satisfactory fragment passage. Calculi in tight, narrowly communicating diverticula are unlikely to respond to EL

  14. 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.

    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.

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.

    Neurofibromatosis type I (Morbus Von Recklinghausen) is an autosomal dominant disorder. The major diagnostic criteria include multiple cutaneous neurofibromas, café au lait spots, that are rarely found in the gastrointestinal tract. 5-25% of these lesions, however, may develop into gastrointestinal stromal tumours. We report the case of a 69-year-old woman with Von Recklinghausen disease. She was admitted due to gastrointestinal bleeding. During surgery we found, among multiple neurofibromatic intestinal lesions, macroscopically different bleeding tumours. They were completely removed. Histological examination revealed gastrointestinal stromal tumour. Using an immunohistological assay, we examined stored specimens from previous operations on the same patient: one anal polyp removed a year ago and tumours removed 32 years ago and regarded as polyps then were re-classified as gastrointestinal stromal tumours. In the discussion, the authors address the issue of which examination of the intestine would be appropriate to find out the source of bleeding in the small intestine and how to distinguish intestinal stromal tumours in the terrain of intestinal neurofibromatosis. Another issue addressed is a screening examination in patients with skin forms of Recklinghausens disease. To successfully manage intestinal bleeding, close cooperation among the surgeon, the endoscopist and the radiologist is indispensable. In order to quickly establish the right diagnosis and subsequently target treatment promptly, it is very helpful to know the patients exact personal medical history and also the possible complications of chronic diseases.

  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

    Background/Aims This study aimed to document the recent etiological spectrum of chronic diarrhea with malabsorption and also to compare features that differentiate tropical sprue from parasitic infections, the two most common etiologies of malabsorption in the tropics. Methods We analyzed 203 consecutive patients with malabsorption. The etiological spectrum and factors that differentiated tropical sprue from parasitic infections were analyzed. Results The most common etiology was tropical sprue (n=98, 48.3%) followed by parasitic infections (n=25, 12.3%) and tuberculosis (n=22, 10.8%). Other causes were immunodeficiency (n=15, 7.3%; 12 with human immunodeficiency virus and 3 with hypogammaglobulinemia), celiac disease (n=11, 5.4%), Crohn's disease (n=11, 5.4%), small intestinal bacterial overgrowth (n=11, 5.4%), hyperthyroidism (n=4, 1.9%), diabetic diarrhea (n=4, 1.9%), systemic lupus erythematosus (n=3, 1.4%), metastatic carcinoid (n=1, 0.5%) and Burkitt's lymphoma (n=1, 0.5%). On multivariate analysis, features that best differentiated tropical sprue from parasitic infections were larger stool volume (P=0.009), severe weight loss (P=0.02), knuckle hyperpigmentation (P=0.008), low serum B12 levels (P=0.05), high mean corpuscular volume (P=0.003), reduced height or scalloping of the duodenal folds on endoscopy (P=0.003) and villous atrophy on histology (P=0.04). Presence of upper gastrointestinal (GI) symptoms like bloating, nausea and vomiting predicted parasitic infections (P=0.01). Conclusions Tropical sprue and parasitic infections still dominate the spectrum of malabsorption in India. Severe symptoms and florid malabsorption indicate tropical sprue while the presence of upper GI symptoms indicates parasitic infections.

  2. Effects of the Paclitaxel and Radiation in the Mucosa of the Small Bowel of Rat

    International Nuclear Information System (INIS)

    Purpose : Paclitaxel is a chemotherapeutic agent with potent microtublue stablelizing activity that arrests cell cycle in G2-M. Because G2-M is the most radiosensitive phase of the cell cycle. Paclitaxel has potential as a cell cycle- specic radio sensitizer. This study was design to investigate the ablity of paclitaxel to increase the radiotoxicity in normal small bowl mucosa of the rat. Methods and Materials : A single intraperitoneal infusion of paciltaxel(10mg/kg). And a single irradiation(8 Gy, x-ray) to the whole abdomen and combination of radiation(8 Gy, x-ray) 24 hours after paclitaxel infusion in the rats were done. The changes of jejunal mucosa. And kinetics of mitotic arrest and apoptosis in the jejunal crypt were defined at 6 hours ? 5 days after each treatment histologically. Results : Paclitaxel blocked jejunal crypt cell in mitosis and induced minmal apoptosis. Mitotic arrest by paclitaxel was peaked at 6 hours after infusion and returned to normal by 24 hours. Radiation induced apoptosis and peaked at 6 hours and returned to normal by 24 hours. Combination of paclitaxel and radiation blocked crypt cell in mitosis at 3 days and induced apoptosis slightly at 6 hours and 24 hours and returned to normal by 3 days. The incidence of apopsis in combined group at 6hours was slightly higher than normal control buy significantly lower than radiation alone group. The major changes of jejunal mucosa were nuclear vesicle and atypia which were appered at 6 hours ? 3 days and returned to normal by 5 days. The degree of mucosal changes are no different in 3 groups except for absence of inflmatory reaction in radiation group. Conclusion : Mitotic arrest by paclitaxel was peaked at 6hours and returned to normal by 24 hours and paclitaxel induced minimal apoptosis. Radiation induced apoptosis, Peaked at 6 hours and returned to normal by 24 hours. Radiation induced apoptosis was less in combined group which suggested that paclitaxel have a radioprotective effech when radiation was given 24 hours after paclitaxel infusion

    2003-01-01

    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.

  4. Surgical therapy of radiation-induced small-bowel lesions. Report of 34 cases with a high share of patients with combined chemotherapy

    International Nuclear Information System (INIS)

    Operations on irradiation-injured bowel are rare, bear a high postoperative mortality, and the procedure of choice (resection vs bypass) is still controversial. Thirty-seven operations on small bowel for late effects of irradiation in 16 years were analyzed retrospectively. Fifty-one percent of the operations were performed in the last four years. Ovarian cancer treated by a combination of radiotherapy and chemotherapy was the most frequent underlying disease of 20 patients (58%) followed by carcinoma of the cervix (eight [24%] of the patients). The median latent period between irradiation and surgery was eight months after the combined radiotherapy/chemotherapy, and 12 months after radiotherapy alone. Thirty operations (81%) were done for small-bowel stricture, four for fistula, and three for perforation. Bypass was performed in 17 patients and resection in 16. Complications (fistula, peritonitis, perforation) occurred after 13 operations (35%). All three patients who developed peritonitis died (mortality, 8.1%): two after resection and one after bypass. Suture-associated complications occurred in three (23%) of 13 cases after single-layer and in three (35%) of 17 cases after two-layer anastomoses. Ten patients are still alive two to 76 months (median, 32 months) after operation, six of them free of tumor. All are underweight and suffer from diarrhea (four to 12 stools per day). Pernicious anemia developed in all six patients surviving more than two years

    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.

    Full Text Available AIM: To evaluate the efficacy of endoscopic diagnosis and therapy for jejunal diverticular bleeding.METHODS: From January 2004 to September 2009, 154 patients underwent double-balloon enteroscopy (DBE for obscure gastrointestinal bleeding. Ten consecutive patients with jejunal diverticula (5 males and 5 females at the age of 68.7 ± 2.1 years (range 19-95 years at Chang Gung Memorial Hospital, Academic Tertiary Referral Center, were enrolled in this study.RESULTS: Of the 10 patients, 5 had melena, 2 had hematochezia, 2 had both melena and hematochezia, 1 had anemia and dizziness. 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.

  9. 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 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 intestinal 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.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.

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.)

    Full Text Available AIM: To evaluate the risk factors-other than nonsteroidal anti-inflammatory drugs-for colonic diverticular bleeding in a westernized population.METHODS: One hundred and forty patients, treated for symptomatic diverticular disease in a community based hospital, were included. Thirty (21% had signs of diverticular bleeding. Age, gender, and the results of colonoscopy were collected and compared to a group of patients with nonbleeding symptomatic diverticulosis. Records were reviewed for comorbidities, such as obesity, alcohol consumption, smoking habits and metabolic diseases. Special emphasis was put on arterial hypertension, cardiovascular events, diabetes mellitus, hyperuricemia and hypercholesterinemia.RESULTS: There was no difference between patients with diverticular hemorrhage and those with nonbleeding symptomatic diverticulosis regarding gender ratio (male/female 9/21 vs 47/63 and diverticular localisation. Bleeding patients differed in respect to age (73.4 ± 9.9 vs 67. 8 ± 13.0, P < 0.013. Significant differences were found between both groups regarding the presence of hyperuricemia and use of steroids and nonsteroidal anti-inflammatory drugs. Patients with three concomitant metabolic diseases were also identified as being at risk of bleeding. A forward stepwise logistic regression analysis revealed steroids, hyperuricemia and the use of calcium-channel blockers as independent risk factors of bleeding.CONCLUSION: Beside nonsteroidal anti-inflammatory steroid drug use, antihypertensive medication and concomitant arteriosclerotic diseases are risk factors for colonic diverticular hemorrhage. Our results support the hypothesis of an altered arteriosclerotic vessel as the source of bleeding.

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

    Reichert, Matthias C; Lammert, Frank

    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.

  17. Danish national guidelines for treatment of diverticular disease

    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.

    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

    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

    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.

  12. 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

    A case of massive hemorrhage from colon of diverticular origin is reported. A complete study of operative specimen allowed precise localization of diverticulum responsible and guidance of histopathologists in their search for the arterial erosion. Histology showed loss of arterial substance with total communication with diverticular lumen. A literature review emphasized vascular relations of diverticuli and the role of stercoliths in the mechanical agression responsible for the massive hemorrhage. It also illustrated the predominance of arteriography in the modern diagnostic and therapeutic approach to these lesions. PMID:3490484

  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)

    Full Text Available Short bowel syndrome most commonly result after bowel resection for necrosis of the bowel. It may be caused by arterial or venous thrombosis, volvolus and in children, necrotizing enterocolitis. The other causes are Crohn,s disease intestinal atresia. The factors influencing the risk on short bowel syndrome are the remaining length of the small bowel, the age of onset, the length of the colon, the presence or absence of the ileo-coecal valve and the time after resection. Besides nutritional deficiencies there some other consequences of extensive resections of the small intestine (gastric acid hypersecretion, d-lactic acidosis, nephrolithiasis, cholelithiasis, which must be diagnosed, treated, and if possible, prevented. With current therapy most patients with short bowel have normal body mass index and good quality of life.

    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.

  6. Absorbable synthetic mesh (910-polyglactin) intestinal sling to reduce radiation-induced small bowel injury in patients with pelvic malignancies

    International Nuclear Information System (INIS)

    Absorbable synthetic mesh (910-polyglactin) was used to create an intestinal sling in six patients undergoing surgical staging of pelvic malignancies prior to radiation therapy. All patients had effective compartmentalization of small intestine out of the pelvis which persisted throughout the duration of radiation therapy. None of the patients developed complications related to the intestinal sling. This technique is well tolerated and has the potential to minimize chronic small intestinal complications caused by radiation therapy for pelvic malignancies

    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

  9. Optimal interfraction interval to minimize small bowel radiation injury in treatment regimens with two fractions per day: an experimental study in a rat model

    International Nuclear Information System (INIS)

    Background: Normal tissue damage in fractionated radiotherapy is influenced by a number of factors including sublethal damage repair and cellular proliferation. The therapeutic benefit of regimens with multiple fractions per day may thus be offset by increased normal tissue injury if there is insufficient time between daily fractions. We examined the influence of interfraction interval on radiation injury of the intestine, an organ at significant risk during treatment of abdominal and pelvic tumors. Methods: A total of 150 male rats were orchiectomized, and a functionally intact loop of small bowel was sutured to the inside of the scrotum. The intestine within this 'artificial hernia' was irradiated twice daily for 9 days with 2.8 Gy fractions at intervals of 0, 2, 4, 6, or 8 h. Animals were observed for development of radiation-induced intestinal complications and euthanized at either 2 weeks and 26 weeks for subsequent histopathologic examination of irradiated and shielded intestine. Results: Increasing the interfraction interval from 0 to 6 h was associated with a statistically significant reduction in intestinal complications (from 53% to 0%, P<0.001), and in Radiation Injury Score (RIS) (from 10 to 6, P<0.01) in long-term observed animals. Extending the interfraction interval to 8 h did not confer additional benefit. Conclusion: An interfraction interval of 6 h minimizes the risk of chronic radiation enteropathy in this rat model

    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.

  17. Technical developments in bowel MRI

    International Nuclear Information System (INIS)

    Magnetic resonance techniques for imaging the gastrointestinal (GI) tract continue to evolve as a result of rapid technical improvement. This review discusses the diagnostic and technical requirements for optimal bowel imaging and to what extent MR is capable of fulfilling these in comparison with established X-ray techniques. New approaches that have recently been demonstrated for the esophagus as well as small and large bowel are described. These developments indicate that MR imaging of the GI tract is likely to make the transition from research development to routine clinical application. (orig.)

    Diverticular disease of the colon is a common disease worldwide. Although the disease is asymptomatic in about 70%-80% of patients, it represents, at least in Western countries, one of the most important gastrointestinal diseases in terms of direct and indirect health costs. Pathogenesis of the disease is still unknown. However, it is the result of complex interactions between colonic structure, intestinal motility, diet and genetic factors. Whilst efficacious preventive strategies remain to ...
