    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

    Diverticula of the small intestine are relatively rare. A retrospective analysis of 4 cases of the practice of Department of General and Hepatopancreatic surgery, University Hospital "Alexandrovska"--Sofia was performed. Two patients are with Meckel diverticulum--the first one with diverticulitis, and the second with perforation and formed abscess cavity. The third case presents a patient with an intestinal loop with diverticula accreted in hernial sack and forth one is with diverticular perforation of the small intestine. All of them underwent surgery. This is accomplished with a literature review presenting the possible diagnostic and treatment modalities applied to this disease. Complications of intestinal diverticulosis often require surgical management in urgent conditions. PMID:23847804

    Volvulus of the intestine is a surgical emergency. Volvulus of the small bowel is more common in children and is most often secondary to malrotation. Small bowel volvulus is an uncommon cause for small bowel obstruction in adults, and is more likely to be secondary to postoperative adhesive bands. Colonic volvulus is a rare cause of large bowel obstruction, but more common than small bowel volvulus. The sigmoid is most frequently involved, with redundant colon as the primary cause.

    Conclusions: Small bowel lymphangiomas can cause gross or occult GI bleeding, anemia, abdominal pain, and/or obstruction. Endoscopists should be aware of this rare tumor and its unique endoscopic features. The optimal treatment is radical excision, since incomplete resection may lead to recurrence. Argon plasma coagulation or polypectomy have been used to achieve endoscopic ablation and palliation of GI bleeding.

    Trans - omental hernia is very rare, accounting to 1-4% of all internal hernias which is an unusual cause of small bowel obstruction. Here we present a case report of a small bowel obstruction in a female due to trans - omental hernia presenting with central abdominal pain, distension and bilious vomiting. She had no previous history of trauma, surgery. Plain X-ray abdomen erect showed multiple air fluid levels with dilated small bowel loops. Emergency laparotomy revealed a segment of congested small bowel loop (ileum) through a defect in greater omentum. On table the herniated bowel loop was reduced and the defect in greater omentum was closed primarily. There was no necessity for bowel resection as it regained normal colour after reduction. Postoperative period was uneventful with complete resolution of symptoms. This case is presented for its rarity and its importance in clinical differential diagnosis of acute abdomen due to small bowel obstruction. PMID:25738033

  11. Small bowel faeces sign in patients without small bowel obstruction

    International Nuclear Information System (INIS)

    Aim: To evaluate frequency and clinical relevance of the 'small bowel faeces' sign (SBFS) on computed tomography (CT) in patients with and without small bowel obstruction (SBO) presenting with acute abdominal or acute abdominal and flank pain. Methods: Abdominal CTs of consecutive patients presenting to the emergency department with abdominal or flank pain over a 6 month period were retrospectively reviewed by six radiologists, independently, for the presence of the SBFS. Examinations with positive SBFS were further evaluated in consensus by three radiologists, blinded to the final diagnosis. The small bowel was graded as non-dilated (4 cm) dilated. The location of SBFS and presence of distal small bowel collapse indicative of SBO was recorded. Imaging findings were subsequently correlated with the final diagnosis via chart review and compared between patients with and without SBO. Results: Of 1642 CT examinations, a positive SBFS was found in 100 (6%) studies. Of 100 patients with a positive SBFS, 32 (32%) had documented SBO. The remaining 68 patients had other non-obstructive diagnoses. SBFS was located in proximal, central, distal and multisegmental bowel loops in one (3.1%), eight (25.0%), 21 (65.6%) and two (6.3%) patients with SBO, and in zero (0%), 10 (14.7%), 53 (77.9%) and five (7.4%) of patients without SBO (p < 0.273). The small bowel was non-dilated and mildly, moderately or severely dilatd and mildly, moderately or severely dilated in one (3%), five (16%), 20 (62%) and six (19%) patients with SBO, and in 61(90%), seven (10%), zero (0%) and zero (0%) patients without SBO. Normal or mildly dilated small bowel was seen in all (100%) patients without SBO, but only in six (19%) of 32 patients with SBO (p < 0.0001). Moderate or severe small bowel dilatation was seen in 26 (81%) patients with SBO (p < 0.0001), but it was absent in patients without SBO. Distal small bowel collapse was found in 27 (84.4%) of 32 patients with SBO, but not in patients without SBO (p < 0.0001). A combination of SBFS, moderate or severe small bowel distension and distal collapse was found in 23 (71.9%) patients with SBO (p < 0.0001), but was not found in patients without SBO. Conclusion: A SBFS is more frequent in patients presenting with acute abdominal/flank pain without bowel obstruction. When seen in association with moderate or severe small bowel dilatation, a SBFS is significantly more common in patients with SBO. When a SBFS is associated with normal or mildly dilated small bowel, the majority of patients have no bowel obstruction

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

  14. Adenocarcinoma of the small bowel

    International Nuclear Information System (INIS)

    Adenocarcinoma of small bowel is generally a rather rare primary tumour of small bowel with a prevalence rate of 0.5 - 3.0 / 100.000 population, but the most frequent tumour of small intestine. It more often involves the duodenum and jejunum than the ileum. The aim of this paper is also to point out the value of small bowel follow through (SBFT) in the diagnosis of stenosing lesions. An 83 - year old male patient suffered from abdominal pain, malaise, vomiting, cachexia and diarrhoea for 3 months. The result of occult blood testing was negative. Haemoglobin level was normal. Proctoscopy, colonoscopy, upper gastrointestinal (GI) endoscopy, and ultrasonography (US) did not explain the patient's problems. Ileus of the small bowel was established with abdominal plain film. Small bowel follow through (SBFT) and computer tomography (CT) showed a stenosing tumour in the jejunum. Adenocarcinoma of the small bowel was established with histological examination after resection of the tumor. SBFT, with manual compression of all segments of the small bowel, can be a very accurate diagnostic investigation for evaluation of stenosing lesions in this part of the intestine. (author)

    Adhesive small bowel obstruction is a frequent cause of hospital admission. Water soluble contrast studies may have diagnostic and therapeutic value and avoid challenging demanding surgical operations, but if bowel ischemia is suspected, prompt surgical intervention is mandatory. A 58-year-old patient was operated for extensive adhesive small bowel obstruction after having had two previous laparotomies for colorectal surgery, and had a complex clinical course with multiple operations and several complications. Different strategies of management have been adopted, including non-operative management with the use of hyperosmolar water soluble contrast medium, multiple surgical procedures, total parenteral nutrition (TPN) support, and finally use of antiadherences icodextrin solution. After 2 years follow-up the patient was doing well without presenting recurrent episodes of adhesive small bowel obstruction. For patients admitted several times for adhesive small bowel obstruction, the relative risk of recurring obstruction increases in relation to the number of prior episodes. Several strategies for non-operative conservative management of adhesive small bowel obstruction have already addressed diagnostic and therapeutic value of hyperosmolar water soluble contrast. According to the most recent evidence-based guidelines, open surgery is the preferred method for surgical treatment of strangulating adhesive small bowel obstruction as well as after failed conservative management. Research interest and clinical evidence are increasing in adhesions prevention. Hyaluronic acid-carboxycellulose membrane and icodextrin may reduce incidence of adhesions. PMID:23054502

  16. Small bowel volvulus in children

    International Nuclear Information System (INIS)

    Two children with small bowel volvulus diagnosed on barium enema examination are reported. In one patient the volvulus was associated with malrotation and in the other patient there was a post-operative peritoneal adhesion. In both cases the diagnosis was based on beaking of the head of the barium column at the site of volvulus. Radiographic demonstration of a beak sign in the small bowel on barium enema examination should suggest a diagnosis of small bowel volvulus, and indicates the need for immediate surgery. (orig.)

  17. Scintigraphic pattern of small bowel bleeding

    International Nuclear Information System (INIS)

    Introduction: Small intestine is the longest part of gastrointestinal tract. Intra-luminal haemorrhage occurring anywhere in its long and tortuous course is difficult to trace. It is relatively inaccessible to endoscopic evaluation. Upper GI endoscopy can see only up to distal duodenum, whereas colonoscope can view maximum of 30 centimeters of terminal ileum after negotiating the scope through ileo-caecal valve. Hence, localization of bleeding source from small bowel remains a difficult clinical problem. This group of patients can be evaluated with scintigraphy for localizing the site of bleeding before undergoing either angiography or surgery. To our best of knowledge, there is no study, which has utilized scintigraphy for evaluation of small bowel bleed exclusively. The present study has been designed to know the efficacy of 99mTc-RBC scintigraphy in detecting small bowel bleed and to know whether it can differentiate between jejunal and ileal bleeding ? Materials and methods: Thirteen patients presenting with lower gastrointestinal bleeding (malena) were enrolled for the study. In all cases, upper GI endoscopy (UGIE) was unremarkable. Colonoscopic examination was either negative or suspected bleeding occurring proximal to ileo-caecal valve. Thus, in these patients, it is presumed clinically that bleeding is originating from small bowel. Barium meal follow through (BMFT) studies, however, could not delineate any etiological lesion in these patients. There were 8 menlesion in these patients. There were 8 men and 5 women (mean age 48 years). All patients were anemic (Hb- 6 gm%) and mean 3 units of blood were transfused.These patients were subjected to Tc-99m labeled red blood cells scintigraphy (15 mci, in-vivo method) for localization of source of bleeding. The scintiscan was acquired in two phases. A first pass phase acquired at a rate of 2 seconds per frame for 60 seconds followed by acquisition of static abdominal images (500 K, 256 x 256 matrix) at 5 minutes intervals up to 90 minutes on LFOV gamma camera fitted with LEAP collimator. Delayed imaging up to 6 hours was optional and was undertaken only when first 90 minutes images did not reveal any site of bleeding. Two nuclear physicians reviewed the sequential static images for 1) First appearance of focus of activity in a particular quadrant/region of abdomen and 2) looking for its migration pattern. Scintigraphic results were prospectively compared with surgical outcome in 10 patients. Results: Tc-99m RBC Scan localized site of bleeding in 10 of 13 patient evaluated (77%). Ten scan positive patients underwent exploratory laprotomy. On surgical exploration, five culprit lesions were identified in jejunum and as many number of lesions were detected in ileum. Etiological lesions were mainly inflammatory or ulcerative (n=5) followed by neoplastic and vascular ectasias in 2 patients each. One patient showed diverticular disease of jejunum as the source of haemorrhage.Tc-99m RBC Scan was able to distinguish between proximal (jejunal) and distal (ileal) small bowel bleeding in 8 of 10 scan positive cases (80%). Scintigraphy correctly localized bleeding in jejunum and ileum in 3 and 5 patients respectively. In majority of patients (7/10, 70%), scan became positive within 3 hours. Six types of scan patterns were noticed in thirteen patients evaluated with Tc-99m RBCs scan. Five scintigraphic patterns were representative of small bowel bleeding. A serpentine appearance of bowel loops in mid abdomen, focal tracer appearance in right iliac region with subsequent outlining of ascending colon on delayed images, and a focus of activity showing distal extension in circular fashion on sequential static images were characteristic of ileal bleeding. Visualization of fixed loop in left flank region corroborated with jejunal lesion (Leiomyoma) in our series. An abnormal blush and early localization of diffuse activity in left upper quadrant followed by its centripetal extension/movement, was seen in patient with jejunitis. Scintigraphy was false negative in cases of systemic diseases

    We describe a rare case of small bowel obstruction and perforation secondary to a primary enterolith in an 84-year-old female patient with jejunal diverticulosis. She underwent an emergency laparotomy, small bowel resection and primary anastomosis. Multiple jejunal diverticula and a large stone were identified at the time of operation. Analysis of the stone demonstrated mainly faecal material consistent with a true primary enterolith. A literature search of Medline and PubMed revealed three cases similar to the one described. The pathogenesis and management of enterolithiasis in jejunal diverticular disease is considered. PMID:24626387

    Full Text Available Small bowel tumours are rare and originate from a wide variety of benign and malignant entities. Adenocarcinomas are the most frequent primary malignant small bowel tumours. Submucosal tumours like gastrointestinal stromal tumours (GIST or neuroendocrine tumours (NET may show a central umbilication, pathologic vessels, bridging folds or an ulceration of the overlying mucosa. These signs help to differentiate them from harmless bulges caused by impression from outside, e.g. from other intestinal loops. Sarcomas of the small bowel are rare neoplasias with mesenchymal origin, sometimes presenting as protruding masses. Benign tumours like lipoma, fibrolipoma, fibroma, myoma, and heterotopias typically present as submucosal masses. They cannot be differentiated endoscopically from those with malignant potential as GIST or NET. Neuroendocrine carcinomas may present with diffuse infiltration, which may resemble other malignant tumours. The endoscopic appearance of small bowel lymphomas has a great variation from mass lesions to diffuse infiltrative changes. Melanoma metastases are the most frequent metastases to the small bowel. They may be hard to distinguish from other tumours when originating from an amelanotic melanoma.

    2012-01-01

    Although most cases of acute pancreatitis are attributed to gallstones or alcohol, many remain idiopathic. The authors describe a case of acute pancreatitis in a 75-year-old gentleman who presented with acute epigastric pain, fevers and shortness of breath. Serum amylase was 2164. CT showed free mesenteric air, and a partly cystic/partly gas-containing mass in the uncinate lobe of the pancreas. Gastrograffin meal revealed duodenal and jejunal diverticular disease, but no contrast leak. Further CT analysis pinpointed fine tracts of air leading from a jejunal diverticulum up toward the pancreas, suggesting causation by a sealed jejunal diverticular perforation. He responded well to intravenous antibiotics and conservative management. Although small bowel diverticular disease is linked to chronic pancreatitis, evidence for association with acute pancreatitis is scarce. The authors believe this is the first reported case of jejunal diverticular disease causing acute pancreatitis, and it highlights micro-perforation as a potential disease mechanism. PMID:22665561

    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.

    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.

    International Nuclear Information System (INIS)

    The indications for small bowel barium examination, the radiologic findings, and the clinical outcome were compared retrospectively in 331 children, aged 0 to 15 years. Sixty examinations (18%) were pathologic, which is in accordance with adult materials. The most common indications for referral were inflammatory bowel disease (48%) and small bowel obstruction (25%). The examinations were positive in 19% and 17%, respectively. Indications for referring patients with non-specific symptoms led to a low frequency of pathologic findings. A therapeutic or diagnostic procedure was performed in 38 of the 60 pathologic radiologic examinations (63%). In 18 patients (30%) a pathologic finding caused no change in therapy. No consistent difference in sensitivity, specificity or predictive values of a positive or negative result was found concerning enteroclysis or elective follow-through examination. For screening purposes of the small bowel in children follow-through examinations give adequate radiologic information and should be used instead of enteroclysis. (orig.)

The current case is unusual as the tumour seemingly originated from the bowel and the well-differentiated component was seen extensively infiltrating the bowel wall including the small bowel submucosa.

  15. Computed tomography features of small bowel volvulus

    International Nuclear Information System (INIS)

    Small bowel volvulus is a cause of acute abdomen and commonly occurs in neonates and young infants. Although it is rare in adults in the Western world,' it is a relatively common surgical emergency in the Middle East, India and Central Africa. It is associated with a mortality rate of 10-67% and, hence, it is important to make an early diagnosis to expedite surgical intervention. Computed tomography has become an important imaging modality in diagnosis and a number of signs have been recognized in a handful of documented case reports. We describe a case of small bowel volvulus that illustrates these important CT signs. Copyright (1999) Blackwell Science Pty Ltd

    A 35-year-old female presented with recurrent right lower quadrant pain, nausea, and vomiting. She was afebrile with diffuse abdominal tenderness. Plain x-ray of abdomen revealed small bowel obstruction. A barium x-ray of the small bowel showed stricture of the terminal ileum. A CT scan of the abdomen showed a 6-cm mass in right lower quadrant. She was empirically managed as having Crohn's disease. She underwent laparotomy after failure of medical management with high-dose steroids. There was ulceration and narrowing of terminal ileum. Frozen sections revealed endometriosis. Ileocecectomy was performed. Histopathology of resected specimen confirmed the diagnosis of endometriosis, and there was no evidence of chronic inflammatory bowel disease or neoplasia. Ileal endometriosis should be considered in the differential diagnosis of Crohn's disease in menstruating females presenting with perimenstrual symptoms. PMID:8174427

    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.

    Small bowel transplantation, alone or with other organs as multivisceral transplantation, is performed for patients with chronic intestinal failure. With advancing surgical techniques and improved post-surgical management, survival of these patients has increased tremendously in the last two decades. The radiologist has an important role in the preoperative and postoperative management of these patients. Knowledge of surgical techniques and post-surgical complications seen in the transplant recipient is necessary for adequate management of these patients. PMID:25489131

    Full Text Available Adhesive small bowel obstruction (ASBO is the most frequently encountered surgical disorder of the small intestine. Up to 80% of ASBO cases resolve spontaneously and do not require invasive treatment. It is important to identify such patients that will benefit from conservative treatment in order to prevent unnecessarily exposing them to the risks associated with surgical intervention, such as morbidity and further adhesion formation. For the remaining ASBO patients, timely surgical intervention is necessary to prevent small bowel strangulation, which may cause intestinal ischemia and bowel necrosis. While early identification of these patients is key to decreasing ASBO-related morbidity and mortality, the non-specific signs and laboratory findings upon clinic presentation limit timely diagnosis and implementation of appropriate clinical management. Combining the clinical presentation findings with those from other diagnostic imaging modalities, such as abdominal X-ray, computed tomography-scan and water-soluble contrast studies, will improve diagnosis of ASBO and help clinicians to better evaluate the potential of conservative management as a safe strategy for a particular patient. Nonetheless, patients who present with moderate findings by all these approaches continue to represent a challenge. A new diagnostic strategy is urgently needed to further improve our ability to identify early signs of strangulated bowel, and this diagnostic modality should be able to indicate when surgical management is required. A number of potential serum markers have been proposed for this purpose, including intestinal fatty acid binding protein and ?-glutathione S transferase. On-going research is attempting to clearly define their diagnostic utility and to optimize their potential role in determining which patients should be managed surgically.

  4. 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 formmands to be more cautious and to call for the methods of parenteral feeding and digestive setting to rest

  5. Pathophysiology of the nodular and micronodular small bowel fold

    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

    Small bowel carcinoid tumours arising from enterochromaffin cells in the jejunum and ileum are neuroendocrine tumours (NETs) characterized by secretion of serotonin, tachykinins and other bioactive substances. These substances may lead to the typical carcinoid syndrome as well as pronounced fibrosis locally and in the heart. Although the most frequent histological subtype of malignancy in the small bowel, small bowel carcinoids are rare and therefore difficult to study. We found that previous...

  11. Surgical management of tuberculous small bowel obstruction

    International Nuclear Information System (INIS)

    Background: Acute intestinal obstruction due to tuberculosis is a common surgical problem in our community. Emergency surgery is usually required and surgical procedure depends upon the location and extent of the disease. The aim of this study was to determine the commonly involved region of intestine and different surgical procedures tailored. Methods: Thirty patients operated upon for acute intestinal obstruction in emergency with operative and histopathological findings suggestive of tuberculosis were included in the study. Demographic profile, operative findings, details of surgical procedure, complications and post-op hospital stay were recorded. The patients were followed for 6 months. Results: Intestinal tuberculosis is more common in young female, with male to female ratio of 1:1.5. Stricture of the small bowel was found in 50% of the cases. The next common finding was ileocaecal tuberculosis found in 40% of patients. Strictruplasty was performed in 11 (36.33%). The right hemicolectomy, limited ileocaecal resection and segmental bowel resection with end to end anastomosis were performed in four patients each. Other procedures were release of adhesions and bands in 4 patients, ileotransverse bypass in 1 patient and loop ileiostomy in 2 patients. Major complication in 10 patient and mortality rate was 10%. Conclusion: Because of non-specific clinical features, ignorance and malpractice intestinal tuberculosis presents late. Ileocecal tuberculosis is becoming leste. Ileocecal tuberculosis is becoming less common as compared to small bowel strictures. Less radical surgery gives better results. Post operative complications and mortality are related to the perforation of the intestine at the time of surgery. (author)

    The accuracy of CT in the detection of injuries of the solid visceral organ is well established, but the value of CT in diagnosing small bowel rupture after abdominal trauma is controversal. This study was conducted to ascertain CT finding of small bowel rupture result from abdominal trauma. A retrospective analysis of preoperative abdominal CT findings in 40 patients was performed. Small bowel rupture was confirmed by surgery. Precontrast and postcontrast enhanced CT images were obtained in all patients. Diagnostic findings of small bowel rupture including pneumoperitoneum or retroperitoneal air, discontinuity of the bowel wall and extravasation of oral contrast materials were observed in 33 cases(83%). Intraperitoneal or retroperitoneal free air was seen in 31 cases(78%) and intraperitoneal or retroperitoneal free fluid collection was seen in 38 patients(95%). Small bowel wall was thickened in 31 cases(78%), bowel wall was enhanced in 12 cases(30%) and bowel wall discontinuity and extravasation of oral contrast material was seen in 5 cases, respectively. The CT scan is sensitive and effective modality for evaluation of small bowel rupture after abdominal trauma, because of high detectability of diagnostic and suggestive CT findings

  18. Diarrhoea due to small bowel diseases.

    2012-10-01

    Small intestinal diseases are a common, though often overlooked cause of diarrhoeal illness. Fully 1% of the Caucasian population are affected by coeliac disease and a substantial portion of children living in poverty in the developing world are affected by environmental enteropathy. These are but two examples of the many diseases that cause mucosal injury to the primary digestive and absorptive organ in our body. While diarrhoea may be a common, though not universally seen symptom of small bowel mucosal disease, the consequent malabsorption can lead to substantial malnutrition and nutrient deficiencies. The small intestine, unlike the colon, has been relatively inaccessible, and systematic evaluation is often necessary to identify and treat small intestinal mucosal diseases that lead to diarrhoea. Immunodeficiency states, including HIV enteropathy, adult autoimmune enteropathy, drug-associated enteropathy, and tropical sprue continue to occur and require specific therapy. All patients with severe diarrhoea or diarrhoea associated with features suggestive of malabsorption may have a disease of the small intestinal mucosa that requires careful evaluation and targeted management.

    We report on a case of a 68-year-old man who was transferred to our department to undergo surgical treatment of intestinal obstruction and a palpable right sided abdominal mass. The abdominal computed tomography scan revealed a small bowel obstruction with an incarcerated spigelian hernia. A mesh repair was performed by suturing the mesh to the internal oblique muscle and to the rectus sheath. The postoperative course was uneventful, and no recurrence has occurred during the 2-year follow-up. An urgent operation should be performed as soon as an accurate diagnosis of incarcerated spigelian hernia has been made. Computed tomography should be helpful in order to establish an accurate diagnosis of the incarcerated hernia. PMID:15045648

  20. 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 tenterography 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.

  1. 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. Conclusid 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.

  3. CT imaging features of phytobezoar associated with small bowel obstruction

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the CT findings of phytobezoar associated with small bowel obstruction. In 19 patients with phytobezoar associated with small bowel obstruction, two of whom had underlying small bowel disease, we analyzed the morphological characteristics of phytobezoars and changes in the bowel and perienteric regions, as revealed by abdominal CT imaging. On CT, phytobezoars appeared as single or multiple, gas-containing masses in 17 patients (89%) and as a solid mass without gas in the remaining two (11%). An encapsulating wall was noted in six patients (32%). Among the 17 without underlying small bowel disease, the bowel wall was thickened in 13 (76%) at the obstructed site and/or the bowel proximal to the obstruction. Mesenteric vascular engorgement and haziness were seen in 18 patients (95%) and a small amount of ascites in six (32%). MR images of one patient showed the phytobezoar as a hypointense mass on all sequences. CT imaging is useful for the diagnosis of phytobezoar associated with small bowel obstruction

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

    International Nuclear Information System (INIS)

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

    Sufficient luminal distension is mandatory for small bowel imaging. However, patients often are unable to ingest volumes of currently applied oral contrast compounds. The aim of this study was to evaluate if administration of low doses of an oral contrast agent with high-osmolarity leads to sufficient and diagnostic bowel distension. Six healthy volunteers ingested at different occasions 150, 300 and 450 ml of a commercially available oral contrast agent (Banana Smoothie Readi-Cat, E-Z-EM; 194 mOsmol/l). Two-dimensional TrueFISP data sets were acquired in 5-min intervals up to 45 min after contrast ingestion.

  6. Intestinal small bowel lymphomas - diagnosis and treatment

    International Nuclear Information System (INIS)

    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.

    Small bowel cancers account for 3% of all gastrointestinal malignancies and small bowel adenocarcinomas represent a third of all small bowel cancers. Rarity of small bowel adenocarcinomas restricts molecular understanding and presents unique diagnostic and therapeutic challenges. Better cross-sectional imaging techniques and development of enteroscopy and capsule endoscopy have facilitated earlier and more-accurate diagnosis. Surgical resection remains the mainstay of therapy for locoregional disease. In the metastatic setting, fluoropyrimidine and oxaliplatin-based chemotherapy has shown clinical benefit in prospective non-randomized trials. Although frequently grouped under the same therapeutic umbrella as large bowel adenocarcinomas, small bowel adenocarcinomas are distinct clinical and molecular entities. Recent progress in molecular characterization has aided our understanding of the pathogenesis of these tumours and holds potential for prospective development of novel targeted therapies. Multi-institutional collaborative efforts directed towards cogent understanding of tumour biology and designing sensible clinical trials are essential for developing improved therapeutic strategies. In this Review, we endeavour to outline an evidence-based approach to present-day management of small bowel adenocarcinoma, describe contemporary challenges and uncover evolving paradigms in the management of these rare 'orphan' neoplasias.

    We present a case of a 42-year-old female who presented to our institution with a small bowel obstruction and had emergent surgical decompression. Thirteen days postoperatively, the patient became tachycardic and had worsening epigastric pain. Electrocardiogram showed significant ST-segment elevations in leads II, III, aVF, and V3–V6, suggesting the possibility of acute inferolateral myocardial infarction. Subsequent workup revealed the cause of the ST-elevations to be due to recurrent small bowel obstruction. Although intra-abdominal causes of ST-elevation have been reported, our case may be the first to be associated with small bowel obstruction. PMID:25838963

  9. Small bowel enteroclysis using a hemodialysis blood pump

    International Nuclear Information System (INIS)

    The purpose of this study is to describe the usefulness of small bowel enteroclysis using a hemodialysis blood pump. Over 1 16 month period, 135 double contrast small bowel enteroclysis examinations were performed in 132 patients using a hemodialysis blood pump. Following incubation of the proximal jejunum, barium at a dilution of 50 % and 0.5 %-methylcellulose were infused at a constant rate using a hemodialysis blood pump and multiple spot films of the small intestine were obtained. Success rate, quality of radiographs, positive findings, fluoroscopic time and complications were evaluated. It spite of the long fluoroscopic time and invasiveness, double contrast small bowel enteroclysis is useful for the evaluation of small bowel disease. The infusion of barium and methylcellulose using a hemodialysis blood pump give radiographs of good quality. (author). 18 refs., 2 tabs., 10 figs

    Malignancy of the small bowel presents unique diagnostic and therapeutic challenges resulting in a delayed diagnosis in many cases. Small-bowel tumors respond poorly to most forms of treatment. Metastatic lesions to the ovaries comprise a small percentage of all ovarian malignant neoplasms. Ovarian metastases from primary small-bowel tumors are often difficult to differentiate from primary ovarian tumors. Only few reports have described ovarian metastases from small-bowel sources. A high index of suspicion can lead to an earlier diagnosis and can have an impact on the therapeutic options as well as the survival of the patients. The current report also underscores the importance of careful review of symptoms, investigative studies and pathology. Images Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 PMID:16749659

  11. 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.)

  12. Oral contrast agents for small bowel distension in MRI: influence of the osmolarity for small bowel distention

    International Nuclear Information System (INIS)

    To assess the effect of the osmolarity for small bowel distension in MRI, ten volunteers ingested at two separate occasions negative oral contrast agents with different quantity and osmolarity: (1) a water solution combined with 2.0% sorbitol and 0.2% locus bean gum (LBG) with a quantity of 1500 ml and an osmolarity of 148 mOsmol/l, (2) a water solution combined with 2.0% sorbitol and 2.0% barium sulphate with a quantity of 1000 ml and an osmolarity of 194 mOsmol/l. Small bowel distension was quantified on coronal 2D-TrueFISP images by measuring the small bowel diameters. There were no statistically significant differences in mean small bowel diameter between both contrast agents. The mean small bowel distension was 19.2 mm after ingestion of 1500 ml of sorbitol-LBG solution and 19.0 mm after ingestion of 1000-ml sorbitol-barium sulphate solution. Furthermore, all volunteers found the ingestion of 1000-ml solution more pleasant than the 1500-ml solution. The ingestion of 1000 ml of sorbitol-barium sulphate solution led to a sufficient small bowel distension compared to 1500 ml of sorbitol-LBG solution. The side effect rate of both solutions was low. Based on these data, we recommend a quantity of 1000 ml of sorbitol-barium sulphate solution as an alternative for 1500-ml sorbitol-LBG solution for optimal bowel distension. (orig.)

    Full Text Available The aim of this study is, could we transform demucosed colon into the small bowel? To find the answer, this study was investigated the surface changes of demucosed colon segment, interposed into the small bowel fashioned as a blind loop. This study was performed in five healthy young stray dogs. A blind loop was fashioned, using a 5 cm long demucosed colonic segment and a 20 cm long ileal segment. Ileal and colonic continuity were restored by primary anastomosis. Four weeks later, blind loop was resected and examined histologically under light microscopy. Histological findings revealed that demucosed colonic segment interposed into the small bowel fashioned as a blind loop, was covered with small bowel epithelium.

  18. Factors predisposing to radiation-related small-bowel damage

    International Nuclear Information System (INIS)

    From 1970 through 1977, 92 patients with ovarian cancer received 20 Gy (2,000 rad) to the abdomen, followed by 30 Gy (3,000 rad) to the pelvis. Small-bowel obstruction developed in 7 (7.6%). 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

  19. Primary small bowel lymphomas: clinico-radiological correlations

    International Nuclear Information System (INIS)

    From 1987 to 1989, 7 patients were diagnosed as having a primary limphoma of the small bowel. The patients, 5 men and 2 women aged 14-66 years (average: 45), were studied by means of small bowel enema and CT. Using small bowel enema, our findings were: masses related to a loop, stenosis, mucosal patterns with thick, irregular, and nodular folds, and bowel walls thickening. In nearly all cases CT showed not only small bowel lesions but also mesenteric lymphadenopathy. Five of seven patients had lymphomas, 1 had IPSID limphoma (immunoproliferative small intestinal disease related lymphoma), and 1 had IPSID associated with a late prelymphomatous stage. The diagnosis of IPSID is very important in patients with malabsorption syndrome, which may or may not be related to alpha heavy chain disease, because IPSID may evolve into limphoma but its prelymphomatous stage can be tratted and cured. We have therefore reported the different features seen with enteroclysis and CT, comparing the results obtained in the various forms of lymphoma of the small bowel. The importance is stressed of an accurate diagnosis of IPSID forms, however uncommon in our Country

  20. CT findings of small bowel metastases from primary lung cancer

    International Nuclear Information System (INIS)

    To evaluate the CT findings of small bowel metastases from primary lung cancer. Of the 1468 patients with primary lung cancer between 1990 and 2000, 13 patients who had metastasis to the small intestine were collected. Of these 13 patients, nine who underwent CT scan were included for analysis. The pathologic diagnoses of primary lung cancer in these nine patients were squamous cell carcinoma in six, adenocarcinoma in two, and large cell carcinoma in one. CT scans were analyzed with regard to the site and patterns (intraluminal mass/bowel wall thickening/bowel implants) of metastatic masses, and the presence or absence of complication such as intussusception, obstruction, or perforation of the small bowel. The medical records of the patients were also reviewed retrospectively for evaluation of presenting abdominal symptom and time interval of metastases from initial diagnosis of lung cancer. Metastatic lesions were distributed throughout the small intestine: the duodenum in five, the jejunum in four, the ileum in six, and both jejunum and ileum in one patient. The size of metastatic masses of small bowel ranged from 1.3 cm to 5.0 cm (mean size, 2.6 cm) On CT, the small bowel was involved with intraluminal masses (mean size, 3.4 cm) in eight patients, diffuse wall thickening (mean thickness, 1.6 cm) in five, and bowel implants (mean size, 2.2 cm) in two. Complications occurred in seven patients, including intussusceptions without obstruction in two patients and with obut obstruction in two patients and with obstruction in two, obstruction without intussusceptions in two, and bowel perforation in one. Of 9 patients, 6 had at least one symptom referable to the small bowel including abdominal pain in 4, anemia in 3, vomiting in 1, and jaundice in 1. Lung cancer and small bowel lesions were detected simultaneously in four patients and the time interval of metastases from initial diagnosis of lung cancer ranged from 10 days to 30 months (median interval, 54 days) in patients. CT helps in defining the extent and pattern of small bowel metastases as well as in demonstrating their complication

    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.

    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 smthose patient with typical transient small bowel intussusceptions. Atypical US findings or clinical deterioration of the patient with persistent intussusception warrant surgical exploration

  7. CT Findings of Small Bowel Anisakiasis: Analysis of Four Cases

    International Nuclear Information System (INIS)

    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

A CT examination should be performed for patients with ileus of unknown cause. (orig.)

    Full Text Available Burkitt lymphoma localised at the small bowell is very rare. We present the case of a 7 years old child admitted into the hospital for acute appendicitis. During the surgical procedure we found a tumor localised on the last segment of the small bowell. We performed appendectomy associated with segmental resection of intestine were the tumor was, with end to end eneteroenterostomy. The microscopic pathological exam showed the infiltration of the intestinal wall with lymphocytes and macrophages with an overall appearance of „starry sky”. Immunehistochemistry revealed malignant B type lymphocytes CD 20 positive, CD 68 positive macrophages and a Ki-67 proliferation index rate of 85%. These findings certified the diagnosis of Burkitt lymphoma. The postoperative course was uneventful. Conclusion: The Burkitt lymphoma of the small bowell can be a „surprising” intraoperatively diagnosis. The treatment of this tumor is surgical procedure (resection of the intestine associated with chemotherapy.

    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.

    Full Text Available Primary malignancies of the small bowel are rare and usually present with vague, non-specific symptoms. This leads to diagnostic difficulties for both physician and radiologists alike. We present a case of a 54-year-old lady with a virgin abdomen who initially presented to hospital with vague abdominal symptoms suggestive of gastroenteritis. She responded partially to conservative treatment but represented to hospital 3 weeks later with obstructive symptoms. Contrast CT was inconclusive with regards to diagnosis. A diagnostic laparoscopy was performed, revealing an infiltrative growth. Consequently, she underwent segmental laparoscopic-assisted small bowel resection and recovered well post-operatively. After further histological and endoscopic investigations, a final diagnosis of primary small bowel adenocarcinoma was given. As the prognosis of small bowel malignancy is stage-dependent, this case demonstrates a high index of suspicion is necessary to reach early diagnosis, especially for symptoms non-responsive to conventional treatment. Diagnostic laparoscopy should be considered early as a definitive diagnostic tool.

    Several studies have indicated that colonic microbiota may exhibit important differences between patients with irritable bowel syndrome (IBS) and healthy controls. Less is known about the microbiota of the small bowel. We used massive parallel sequencing to explore the composition of small bowel mucosa-associated microbiota in patients with IBS and healthy controls. We analysed capsule biopsies from the jejunum of 35 patients (26 females) with IBS aged 18-(36)-57 years and 16 healthy volunteers (11 females) aged 20-(32)-48 years. Sequences were analysed based on taxonomic classification. The phyla with the highest total abundance across all samples were: Firmicutes (43%), Proteobacteria (23%), Bacteroidetes (15%), Actinobacteria (9.3%) and Fusobacteria (7.0%). The most abundant genera were: Streptococcus (19%), Veillonella (13%), Prevotella (12%), Rothia (6.4%), Haemophilus (5.7%), Actinobacillus (5.5%), Escherichia (4.6%) and Fusobacterium (4.3%). We found no difference among major phyla or genera between patients with IBS and controls. We identified a cluster of samples in the small bowel microbiota dominated by Prevotella, which may represent a common enterotype of the upper small intestine. The remaining samples formed a gradient, dominated by Streptococcus at one end and Escherichia at the other. PMID:25687743

    The use of low-dose aspirin (LDA) is well known to be associated with an increased risk of serious upper gastrointestinal complications, such as peptic ulceration and bleeding. Until recently, attention was mainly focused on aspirin-induced damage of the stomach and duodenum. However, recently, there has been growing interest among gastroenterologists on the adverse effects of aspirin on the small bowel, especially as new endoscopic techniques, such as capsule endoscopy (CE) and balloon-assisted endoscopy, have become available for the evaluation of small bowel lesions. Preliminary CE studies conducted in healthy subjects have shown that short-term administration of LDA can induce mild mucosal inflammation of the small bowel. Furthermore, chronic use of LDA results in a variety of lesions in the small bowel, including multiple petechiae, loss of villi, erosions, and round, irregular, or punched-out ulcers. Some patients develop circumferential ulcers with stricture. In addition, to reduce the incidence of gastrointestinal lesions in LDA users, it is important for clinicians to confirm the differences in the gastrointestinal toxicity between different types of aspirin formulations in clinical use. Some studies suggest that enteric-coated aspirin may be more injurious to the small bowel mucosa than buffered aspirin. The ideal treatment for small bowel injury in patients taking LDA would be withdrawal of aspirin, however, LDA is used as an antiplatelet agent in the majority of patients, and its withdrawal could increase the risk of cardiovascular/cerebrovascular morbidity and mortality. Thus, novel means for the treatment of aspirin-induced enteropathy are urgently needed. PMID:25501289

    Magnetic reasonance (MR) enterography enables high contrast resolution depiction of the location and cause of bowel obstruction through a combination of predictable luminal distension and multiplanar imaging capabilities. Furthermore, because the patient is not exposed to ionizing radiation, sequential 'dynamic' MR imaging can be performed repeatedly over time further facilitating depiction of the site and/or the cause of obstruction. With increasing availability of MR imaging and standardization of the oral contrast medium regimens, it is likely that this technique will assume an ever-increasing role in the evaluation of small bowel dilation in the coming years. We illustrate the utility of MR enterography in the evaluation of small bowel dilation, whether it be mechanical, functional (e.g., ileus), or related to infiltrative mural disease.

    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.

    Sclerosing mesenteritis is associated with a spectrum of diseases which include mesenteric lipodystrophy and mesenteric panniculitis. This inflammatory and fibrosing disorder can affect the small and large bowel wall and mesenteric vessels by exerting a mass effect. The following case highlights the difficulties with diagnosing and managing this unusual disease. A 64-year-old man presented with acute central abdominal pain, radiating to his back, and profuse vomiting. He was diagnosed clinically with small bowel obstruction. He had had an episode of small bowel obstruction 6 years earlier. At this time, he underwent an exploratory laparotomy, and a mass was identified in the small bowel mesentery. The features were thought to be in keeping with sclerosing mesenteritis. He had a dramatically favourable response to the initiation of prednisolone. He continued to be well and asymptomatic for a further 5 years on long-term maintenance low-dose steroids and 6-mercaptopurine. He re-presented in 2009 (six years after initial presentation) with very severe acute abdominal pain and vomiting. He had no recent change in weight or appetite, and had not had time off work. He underwent a second laparotomy and the tissue diagnosis was of metastatic carcinoid tumour involving the small bowel mesentery. This is the first case to our knowledge where sclerosing mesenteritis has been confirmed histologically on biopsy and then subsequently diagnosed with histologically proven carcinoid tumour. For this particular reason it must be always remembered that sclerosing mesenteritis is a 'pathological' and not a radiological diagnosis and that a large proportion of cases are associated with neoplasia.

    Full Text Available Abstract Background Diarrhea is common in HIV/AIDS patients, caused by both classic enteric pathogens and different opportunistic agents. Infection with these different pathogens may lead to similar radiological findings, thus causing diagnostic confusion. Case presentation A 30-yr-old female with AIDS presented with chronic diarrhea of 4 months duration. She had diffuse small bowel thickening present on CT scan of her abdomen, with stool examination showing no parasites. She was erroneously diagnosed as abdominal tuberculosis and given antituberculosis drugs with which she showed no improvement. Repeat stool examination later at a specialized laboratory revealed Cryptosporidium parvum infection. The patient was given an extended course of nitazoxanide treatment, as her stool examination was positive for Cryptosporidium parvum even after 2 weeks of drug consumption. Parasite clearance was documented after 10 weeks of treatment. Interestingly, the bowel thickening reversed with parasitological clearance. Conclusions Cryptosporidium parvum may lead to small bowel thickening in AIDS patients. This small bowel thickening may reverse following parasitological clearance.

  8. 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 t haustration is also observed associated to colonic elongation and dilatation

    Accidental ingestion of foreign bodies is a common problem in infants and childhood, but ingestion of magnetic construction toys is very rare. In the case of ingestion of multiple parts of these magnetic construction toys, they may attract each other through the intestinal walls, causing pressure necrosis, perforation, fistula formation or intestinal obstruction. A 20-month-old boy presented with a three-day history of abdominal pain and bilious vomiting. Physical examination revealed a slighted distended abdomen. The -white blood cell count was increased, but the C-reactive protein was normal. Ultrasound and X-ray of the abdomen showed a distended bowel loop in the right upper quadrant, a moderate amount of free intraperitoneal liquid and 4 foreign bodies. Emergency laparotomy was performed and 2 perforations in the ileum were detected. The perforations were caused by a magnetic construction toy and 2 iron globes. The fourth foreign body was a glass marble. The foreign bodies were removed, both perforations were primarily sutured. The child was discharged on postoperative day 10 after an uneventful recovery. Parents should be warned against the potential dangers of children's constructions toys that contain these kinds of magnets. PMID:20549590

  10. The lack of impact of pelvic irradiation on small bowel mobility: implications for radiotherapy treatment planning

    International Nuclear Information System (INIS)

    Purpose: Small bowel contrast is frequently used during simulation for patients undergoing pelvic radiotherapy to assist in the design of blocks that exclude small bowel from the radiation field. In many instances, a large field is treated to 45 gray (Gy), followed by a field reduction to exclude the small bowel. This prospective study was designed to assess whether the position and mobility of the small bowel changed after the initial 45 Gy, thereby determining whether a special small bowel series done at initial simulation is applicable at the time of field reduction. Methods and Materials: Twelve patients undergoing pelvic irradiation were given small bowel contrast for their initial simulation. Radiographs were taken with the bladder empty and the bladder full. The location of the small bowel and its displacement with bladder distention was measured. This entire procedure was repeated prior to field reduction (after 39.6-46.0 Gy). Results: There was no demonstrable alteration in small bowel mobility after 39.6-46.0 Gy. The approximate position of the small bowel relative to bony landmarks was unchanged. Conclusion: The position and mobility of the small bowel appears not to be affected by 39.6-46.0 Gy of pelvic radiotherapy. Therefore, it is reasonable to design reduced pelvic fields to exclude the small bowel based on special small bowel series done at initial treatment simulation

    Mesenteric lymphangiomas are rare abdominal masses that are seldom associated with small bowel volvulus, and especially in adult patients. We report here on an unusual case of small bowel volvulus that was induced by a mesenteric lymphangioma in a 43-year-old man who suffered from repeated bouts of abdominal pain. At multidetector CT, we noticed whirling of the cystic mesenteric mass and the adjacent small bowel around the superior mesenteric artery. Small bowel volvulus induced by the rotation of the mesenteric lymphangioma was found on exploratory laparotomy. Lymphangioma should be considered as a rare cause of small bowel volvulus in adult patients.

    Energy Technology Data Exchange (ETDEWEB)

    Ekberg, O.; Kullenberg, K.

    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.

    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

    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.

    Cystic lymphangioma is an uncommon mesenteric tumor which is usually reported in children. We describe a case of a 12-years old girl who was admitted in our hospital with abdominal distension and pain. Physical examination showed an abdomino-pelvic mass. Preoperative studies including abdominal ultrasonography and computed tomography failed to determine the cause of the pain. Laparotomy found a giant cystic tumor of the small bowel mesentery. Histological studies confirm the diagnosis of cyst...

    A 56-year-old man was hit by a car while riding a bicycle, immediately brought to the hospital, and treated. Four days after the accident, he reported abdominal pain and vomiting in the night, and he died the next day. A forensic autopsy was performed, and almost of the entire small bowel had gangrenous swelling. The mesentery was twisted 180° with clockwise rotation along the vascular axis, and pre-autopsy computed tomography scan showed a whirl sign. PMID:24916863

    2011-01-01

    Full Text Available Transmesenteric hernias are extremely rare. A strangulated hernia through a mesenteric opening is a rare operative finding. Preoperative diagnosis still is difficult in spite of the imaging techniques currently available. The authors describe two cases of paediatric patients presenting with bowel obstruction resulting from a congenital mesenteric hernia. The first patient had a 3-cm wide congenital defect in the ileal mesentery through which the sigmoid colon had herniated. The second patient is a newborn infant who presented with symptoms and radiographic evidence of neonatal occlusion. At surgical exploration, a long segment of the small bowel had herniated in a defect in the ileal mesentery. A brief review of epidemiology and anatomy of transmesenteric hernias is included, along with a discussion of the difficulties in diagnosis and treatment of this condition.

    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. Thi...

  6. 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 presenc 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.

  7. 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.

    Closed loop obstruction represent a surgical emergency, because this lesion leads to small bowel infraction, perforation, and peritonitis if not treated in time. We analyzed the CT and ultrasonographic findings of 4 patients prospectively and 2 patients retrospectively with surgically proven closed loop obstruction of the small bowel to evaluate the characteristic findings, the cause of the closed loop obstruction and predictive criteria for the viability of the involved bowel loop. The characteristic CT and sonographic features of the closed loop obstruction of the small bowel included; dilated fluid-filled bowel loops, the thickened bowel wall, absence of peristalsis, and ascites. In one case, closed loop obstruction originating from umbilical hernia was documented by CT and sonography. The possible criteria for the gangrenous changes could be the maximal thickness of bowel more than 7mm, and infiltration in the mesentery/omentum.

    International Nuclear Information System (INIS)

    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 obstruc5 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

    The standard technique for percutaneous gastrostomy requires insufflation of air into the stomach via a nasogastric tube before percutaneous gastric puncture. We present a previously undescribed complication in which the insertion of a percutaneous gastrostomy tube resulted in the distention of a previously undiagnosed giant small bowel diverticulum. This led to discomfort for the patient, further radiologic investigation and a delay in discharge. Symptoms resolved with conservative management. We suggest a strategy for avoiding this complication, as well as for reducing the incidence of post-procedure ileus. (author)

    The case of an 18-year-old female, with mild left hypochondrial pain and an abdominal mass mimicking gross splenomegaly, with severe small and large bowel fibrosis and adhesions and numerous mononuclear cellular infiltrate on histology, is presented. A clear picture of intestinal obstruction only unfolded terminally. She died within 48 hours of presentation. Our patient illustrates the fact that severe intestinal adhesions may present with very mild symptoms and signs and therefore a high index of suspicion is necessary, to reduce the attendant high mortality in intestinal obstruction in our environment.

    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.

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.

    Full Text Available Introduction. Adenocarcinoma of the small bowel is a rare gastrointestinal neoplasm usually affecting the distal duodenum and proximal jejunum. Because of their rarity and poorly defined abdominal symptoms, a correct diagnosis is often delayed. Case Outline. We present a 43-year-old woman admitted at the Clinic for Endocrinology due to a large tumor (over 7 cm of the left adrenal gland. The tumor was detected by ultrasound and confirmed by CT scan. The patient complained of abdominal pain in the left upper quadrant, fatigue and septic fever. Normal urinary catecholamines excluded pheochromocytoma. The endocrine evaluations revealed laboratory signs of subclinical hypercorticism: midnight cortisol 235 nmol/L, post 1 mg - overnight Dexamethasone suppression test for cortisol 95.5 nmol/L and basal ACTH 4.2 pg/mL. Plasma rennin activity and aldosterone were within the normal range. Surgery was performed. Intraoperative findings showed signs of acute peritonitis and a small ulceration of the jejunum below at 70 cm on the anal side from the Treitz’s ligament. Adrenal glands were not enlarged. Patohistology and immunochemistry identified adenocarcinoma of the jejunum without infiltration of the lymphatic nodules. The extensive jejunal resection and lavage of the peritoneum were performed. Due to complications of massive peritonitis, the patient died seven days after surgery. Conclusion. Poorly defined symptoms and a low incidence make the diagnosis of small bowel carcinoma, particularly of the jejunal region, very difficult in spite of the new endoscopic techniques.

    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

    Full Text Available Volvulus of the small bowel, although being rare, carries a high risk of strangulation and ischemic necrosis. Preoperative diagnosis is difficult and may be complicated by pregnancy, labor and the post-cesarean-section state. Delay in diagnosis and surgical intervention increases morbidity and mortality rates.We present a 20- year- old primigravida woman (GA=10 weeks with massive intestinal necrosis. Her initial symptoms were abdominal pain and nausea. Her complaints were attributed to pregnancy and she came with acute surgical abdomen. Emergent laparotomy was performed. Gangrenous, distended loops of small intestine passed through a defect in the mesentery were resected. Primary end to end anastomosis of jejunum and ileum was done and the defect causing volvulus was repaired. It is concluded that surgical acute abdomen must be considered in differential diagnosis of abdominal discomfort in pregnancy. In the case of small bowel volvulus early surgery is mandatory to reduce the risk of gangrene, which is known as doubling the mortality rate.

    We present the case of a 77-year-old male who was referred for magnetic resonance (MR) enteroclysis because of small bowel subobstruction. To optimise small bowel distention during MR, a nasojejunal balloon catheter was placed to perfuse iso-osmotic water solution into the small bowel. However, after deflation of the balloon, the catheter could not be removed by gentle traction. Subsequently, computed tomography (CT) of the abdomen revealed that the catheter was strangulated deep in the jejun...

    Radiation associated small bowel injury results from aggressive treatment of pelvic malignancies with radiation therapy. The incidence increases when radiation therapy follows pelvic surgery due to adhesions that form between the small bowel and the operated site. Application of an absorbable polyglycolic acid mesh to keep the small bowel from descending into the pelvis and around the operated site prevents this complication. Use to date in humans and non-human primates has not been associated with any complications.

    2011-09-01

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

  4. Small-bowel carcinoid presenting with acute bleeding detected upon wireless capsule endoscopy

    International Nuclear Information System (INIS)

    Background. Intestine carcinoid usually presents with clinical symptoms and signs deriving from its endocrinological influences and rarely bleeds profusely. Case report. We present a patient with intestinal bleeding of unknown origin. After conventional diagnostic procedures only wireless capsule endosopy was able to discover a tumour of small bowel, which was the reason of bleeding. On patohistological examination after the surgical resection it proved to be a small bowel carcinoid. Conclusions. There are indications that WCE, besides being the first small bowel imaging technique, is a very important diagnostic tool, deserving consideration in the early phases of diagnosing small-bowel disease, especially in less intensive or occult bleeding.

    A volvulus, which is torsion of the bowel and its mesentery, is a medical emergency. Small bowel volvulus rarely occurs in adults, although it has been reported in the presence of small bowel diverticulum. Multislice computed tomography (CT) angiography, by demonstrating the mesenteric vessels, can be of help in the diagnosis of small bowel volvulus, especially when CT or gastrointestinal studies fail to show the diverticulum. We present the multislice CT angiography findings of a 64-year-old woman with chronic intermittent volvulus resulting from jejunal diverticulosis, surgically confirmed. To our knowledge, no similar case has been reported previously in the literature. PMID:20661698

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.

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.

  7. 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 diographs. CT also helps to determine the site and cause of the obstruction with good sensitivity. (orig.)

    2010-01-01

    OBJECTIVE: Compared to other modalities, capsule endoscopy (CE) has a high diagnostic yield for diagnosing small bowel Crohn's disease (CD). The aim of this study was to determine the inter-observer agreement for detection of small bowel CD with predefined diagnostic criteria. MATERIAL AND METHODS: Thirty patients with suspected or known CD were included in the study. Observers were blind to patient histories, the results of ileo-colonoscopies, and small bowel examinations. More than three ulcerations (aphthous lesions or ulcers) or the presence of stenosis caused by inflammation or fibrosis was diagnostic of small bowel CD. Three observers with experience in gastrointestinal endoscopy and CE participated in the study. RESULTS: The presence or absence of small bowel CD was determined with complete agreement in 23 patients, nine patients with and 14 without small bowel CD. The inter-observer agreement was substantial for the diagnosis (kappa = 0.68) and moderate for the localization of CD (kappa = 0.44). Aphthous lesions were detected with only fair agreement (kappa = 0.38). The time intervals to passage of the pylorus and ileo-caecal valve were detected with excellent intra-class correlation. CONCLUSIONS: CE is performed with substantial inter-observer agreement for detection of small bowel CD. In the majority of patients, the presence or absence of small bowel CD is unequivocal. However, in patients with few or minor lesions, the diagnosis is observer dependent.

  12. 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)

    Full Text Available Abstract Background Carcinoma of the colon may present with perforation proximal to the site of malignancy. Caecum is the commonest site of perforation if the ileocecal valve is patent and the jejunal and ileal perforations are very rare. Case presentation A 35 year male presented with intestinal obstruction. Emergency laparotomy revealed carcinoma of the transverse colon with multiple pinpoint perforations along antimesenteric border of ileum, which were wrapped with omentum, and no peritoneal contamination was present. Extended right hemicolectomy with jejunocolic anastomosis was done. Patient made uneventful recovery in postoperative period and was treated with adjuvant chemotherapy. Conclusion Patients with colonic carcinoma and incompetent ileocecal valve may present with intestinal perforation. Increased intraluminal pressure and closed loop obstruction may lead to ischemia and perforation of the small bowel.

    2010-03-01

    A telemetry capsule system was designed and implemented to measure the slow wave activity of the small bowel, which is an important parameter for the diagnosis of gastric diseases. The capsule amplified the slow wave signal from the intraluminal electrodes, and transmitted the digitally sampled data by means of a radio frequency transmitter. The implemented capsule (11 x 21 mm(2)) was smaller than a commercially available capsule endoscope, and it can remain active for more than 18 h. The feasibility of using this capsule was investigated by conducting in vitro experiments, and the average motility signals of the ileum, jejunum, and colon were measured as 6.1, 10.2, and 1.5 cycles per minute, respectively.

    A report of alveolar soft part sarcoma metastatic to the small bowel is presented. Hematogenous metastases to the small bowel from primary tumors outside the abdominal cavity are uncommon, and most remain asymptomatic and are not discovered until autopsy. However, small bowel metastases can lead to intestinal obstruction, intussuseption or even perforation. While metastases to the small bowel have been described for other tumor types, including melanoma and lung cancer, this is extremely uncommon for sarcoma, especially alveolar soft part sarcoma. We describe a 42-year-old male with a long history of alveolar soft part sarcoma, metastatic to the lung and brain, who developed an intussuseption from metastases to the small bowel. PMID:18521439

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

    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.

    We wished to evaluate the usefulness of helical CT for the diagnosis of strangulation of the dilated small bowels. The CT scans of 31 patients with small bowel obstruction from various causes were reviewed retrospectively. Thirteen of these patients were confirmed as small bowel strangulation by surgery and pathology. Fourteen patients underwent surgery, but they had no strangulation. Three patients were reduced by using a nasogastric tube and one infant with intussusception was reduced by air reduction. The following CT findings of strangulation were evaluated: reduced bowel wall enhancement by visual assessment and measuring the HU, ascites, thickening of bowel wall, abnormal mesenteric vessel location and whirlpool appearance, and mesenteric venous engorgement. For the precise evaluation of reduced bowel wall enhancement, the HUs were measured by 1 mm{sup 2} of ROI, and the differences of HUs between the well enhanced bowel and poorly enhanced bowel were compared. For the diagnosis of strangulation, measurement of HU of the bowel wall could improve the sensitivity from 69% to 100%. The specificity of both methods, by visual assessment and measurement of HU, was 94%. Ascites had a sensitivity of 69% and specificity of 44%. Thickening of bowel wall had a sensitivity of 38% and specificity of 78%. Abnormal mesenteric vessel location and whirlpool appearance had a sensitivity of 38% and specificity of 83%. Mesenteric venous engorgement had a sensitivity of 31% and specificity of 72%. Measurement of HU of the bowe wall after contrast enhancement can be a useful method in the differential diagnosis between the strangulated and non-strangulated bowels in patients with small bowel obstruction.

  19. 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.)

    Sclerosing mesenteritis is a rare inflammatory disease of the bowel mesentery of unknown aetiology. It poses a diagnostic challenge for clinicians, as it can be mistaken for malignancy. We report a case of sclerosing mesenteritis initially presented with abdominal pain, tender abdominal mass and small bowel obstruction. Emergency laparotomy revealed fibrous thickening of the small bowel mesentery mimicking small bowel lymphoma. An ileo-ileal bypass procedure was performed. Six months later, the patient developed retroperitoneal fibrosis, manifesting as bilateral obstructive uropathy. Our case is unique, as it describes retroperitoneal fibrosis developing in a patient with small bowel retractile mesenteritis, with no evidence of colonic or other anatomical involvement. Furthermore, the patient had no risk factors for this condition. We conclude that the presence of sclerosing mesenteritis should cue clinicians to search for other coexisting inflammatory disorders that can have serious sequelae. PMID:17099377

    In radiotherapy for cervix cancer, both 3-dimensional radiotherapy (3D-CRT) and intensity-modulated radiation therapy (IMRT) could reduce the dose to the small bowel (SB), while the small bowel displacement system (SBDS) could reduce the SB volume in the pelvic cavity. To evaluate the effect of the SBDS on the dose to the SB in 3D-CRT and IMRT plans, 3D-CRT and IMRT plans, with or without SBDS, were compared. Ten consecutive uterine cervix cancer, receiving curative radiotherapy, were accrued. Ten pairs of computerized tomography (CT) scans were obtained in the prone position, with or without SBDS, which consisted of a Styrofoam compression device and an individualized custom-made abdominal immobilization device. Both 3D-CRT, using the 4-field box technique, and IMRT plans, with 7 portals of 15 MV X-ray, were generated for each CT image, and prescribed 50 Gy (25 fractions) to the isocenter. For the SB, the volume change due to the SBDS and the DVHs of the four different plans were analyzed using paired t-tests. The SBDS significantly reduced the mean SB volume from 522 to 262 cm{sup 3} (49.8% reduction). The SB volumes that received a dose of 10 {approx} 50 Gy were significantly reduced in 3D-CRT (65 {approx} 80% reduction) and IMRT plans (54 {approx} 67% reduction) using the SBDS. When the SB volumes that received 20 {approx} 50 Gy were compared between the 3D-CRT and IMRT plans, those of the IMRT without the SBDS were significantly less, by 6{approx} 7%, than those for the 3D-CRT without the SBDS, but the volume difference was less than 1% when using the SBDS. The SBDS reduced the radiation dose to the SB in both the 3D-CRT and IMRT plans, so could reduce the radiation injury of the SB.

  2. Minimization of small bowel volume within treatment fields utilizing customized belly boards

    International Nuclear Information System (INIS)

    Thirty consecutive patients with pelvic malignancies were evaluated prospectively for the impact of a novel bowel minimization device (belly board) on the volume of small bowel included within a four field pelvic radiation plan. A customized polyurethane and styrofoam bowel immobilization mold was created for each patient in the prone position. Using contrast enhanced CT scanning on a dedicated radiation treatment planning scanner, we imaged the location of the small intestine in the supine position and the prone position aided by the belly board. Custom in-house interactive image analysis software was developed to allow volumetric determination of small bowel within the treatment portals. The mean small bowel volume was reduced by 66% (299 cm3 to 102 cm3), comparing the standard supine position to the prone position assisted by the belly board. In 13 patients without prior pelvic surgery, the small bowel volume reduction was a more dramatic 74% (334 cm3 to 88 cm3). All patients were found to benefit from this prone belly board setup regardless of body habitus, weight, and age. Compliance with the set-up including use of bladder distension was excellent. All patients completed their pelvic radiotherapy without requiring a treatment break. Weight loss at completion averaged less than 5%. Seventy-six percent of patients experienced little or no diarrhea. This technique is comfortable, inexpensive, highly reproducible, and permits maximal bowel displacement from standards maximal bowel displacement from standard pelvic radiotherapy fields

    Knotting of a peritoneal catheter around a loop of bowel is a rare occurrence, which may lead to bowel obstruction. The incomplete removal of two ventriculoperitoneal shunts resulted in two cases of iatrogenically knotted peritoneal catheters. One patient underwent a laparotomy for relief of obstruction and the other was successfully treated by uncoiling the catheter by means of a wire passed into its lumen. A plan for management of a knotted peritoneal catheter is outlined. PMID:7760179

    Full Text Available Complicated inguinal hernia is a common surgical emergency. Rarely, hernias may pose a great surprise and complexity in their management.We report a 55 year old gentleman witha long standing history of irreducible right inguinal hernia who presented in shock with sudden increase in size of scrotum and obstipation for 1 day.A diagnosis of strangulated inguinal hernia was made and the patient was taken up for emergency surgery.On exploration the content in the sac was normal small bowel and faeculant smelling fluid. Abdomen was explored for inspecting the proximal bowel and to facilitate reduction of contents.But as a surprise small bowel volvuluswith gangrenous bowel was noted. Resection and anastomosis was done.This paper stresses the importance of having a high index of suspicion in all cases of strangulated hernia of a concomitant small bowel volvulus as its recognition and early surgical intervention is paramount in reducing the mortality associated with it.

  7. Goblet Cell Carcinoid Tumor of the Appendix with Small Bowel Obstruction: A Case Report

    International Nuclear Information System (INIS)

    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

    Two children with small bowel volvulus diagnosed on barium enema examination are reported. In one patient the volvulus was associated with malrotation and in the other patient there was a post-operative peritoneal adhesion. In both cases the diagnosis was based on beaking of the head of the barium column at the site of volvulus. Radiographic demonstration of a beak sign in the small bowel on barium enema examination should suggest a diagnosis of small bowel volvulus, and indicates the need for immediate surgery.

    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.

    Intrauterine devices (IUD) are frequently used as a family planning procedure in developing countries because they are easy to administer and governmental policies support their use in many countries. It is recommended that IUDs be removed or replaced after 10 years, but longer use is common, especially in developing countries. In some cases, rare infections such as pelvic inflammatory diseases, pelvic tuberculosis, or abdominopelvic actinomycosis related to IUD can develop. Pelvic actinomycosis is a rare disease and is often diagnosed incidentally during surgery. In recent years, there has been an increase in actinomycotic infections mostly due to long-term usage of IUD and forgotten intravaginal pessaries. It usually develops as an ascending infection. It is usually associated with non-specific symptoms such as lower abdominal pain, menstrual disturbances, fever, and vaginal discharge. The disease is sometimes asymptomatic. The rate of accurate preoperative diagnosis for pelvic actinomycosis is less than 10%, and symptoms and imaging studies sometimes mimic pelvic malignancy. This report details a case with abdominopelvic actinomycosis associated with an IUD presenting with highly elevated thromboctye count and small bowel perforation with abscess formation.

    A 60-year-old woman with a medical history of celiac disease was evaluated due to recurrent episodes of small bowel obstruction. Upper and lower endoscopies were normal. The small bowel pathology consisted of celiac disease, and the anti-endomysial antibody was positive. Dilatation of small bowel loops was demonstrated on abdominal computed tomography. Further evaluation was conducted using video capsule endoscopy that demonstrated regional narrowing and severe ulceration in the middle of the small bowel. Upper and lower double balloon endoscopies failed to demonstrate the lesion. On explorative laparotomy a small bowel mass in the proximal ileum was excised. Pathology revealed ulcerated, well to moderately differentiated adenocarcinoma without regional nodal involvement. We discuss the etiology and treatment of small bowel carcinoma. This case emphasizes that a high level of suspicion is required in order to diagnose early stage small bowel adenocarcinoma in celiac patients. PMID:24733274

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

    International Nuclear Information System (INIS)

    Objective: The purpose of this work is to prospectively evaluate high resolution ultrasonography with graded compression in the ability to detect Crohn's disease of the small bowel (CDSB) together with its complications and activity signs, compared with enteroclysis, CT and immunoscintigraphy in the mirror of the final diagnosis. Methods and material: In a series of 73 consecutive patients, who were referred for enteroclysis with suspected Crohn's disease of the small bowel computed tomography (CT), ultrasound (US), immunoscintigraphy with 99mTc labeled monoclonal antigranulocyte antibody (AGAb) examinations were performed within 10 days from each other. For the final evaluation the diagnosis of CDSB was based on combination of clinical and enteroclysis findings (73 cases) and in 17 cases additional surgical and pathological data were available. The results of other modalities were blinded to the radiologists performing and reading out the exams. The diagnostic values of each modality was assessed also in those 18 patients, who had early Crohn's disease. In the group of 43 patients with proven CDSB who had all the four imaging modalities, the modalities were compared in their ability to demonstrate various pathological conditions related to CD. Increased (>500 ml/min) flow measured by Doppler US in the superior mesenteric artery and increased color signs in the gut wall seen by power Doppler sonography were compared to CDAI. Results: Of the 73 patients the 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

    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.)

    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 app...

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

    Small bowel angioedema induced by angiotensin converting enzyme (ACE) inhibitors is a rare and often-unrecog- nized condition that presents with transient abdominal pain, nausea and vomiting. We report a case diagnosed in a 36 year-old female. Ultrasound and CT showed segmental small bowel wall thickening and straightening associated with marked submucosal edema and ascites. Laboratory tests only revealed mild leukocytosis. The patient improved spontaneously. PMID:25603633

    Although accounting for 90 % of the intestinal surface area, small bowel adenocarcinomas are not common. The majority of these lesions are incidentally detected during laparotomy for intestinal obstruction or perforation. The symptoms associated with these lesions are not very specific and preoperative diagnosis is rare. We report two cases of jejunal adenocarcinomas detected in patients undergoing laparotomy for acute abdomen and review the literature for small bowel adenocarcinomas.

    Small bowel adenocarcinoma (SBA) is a rare, aggressive malignancy with a poor prognosis, and the mechanisms of carcinogenesis in SBA remain unclear. Our aims were to investigate the molecular mechanisms underlying SBA and to identify treatments by establishing and characterizing an SBA cell line and performing anti-cancer drug screening. SIAC1 cells, established from jejunal SBA, showed epithelial characteristics and formed organoids in 3D culture. SIAC1 cells had a heterozygous ?-catenin deletion mutation, resulting in a stable ?-catenin protein with enhanced Wnt/?-catenin activity. SIAC1 cells lacked MLH1 and MSH6 expression, and target genes such as TGFBR2 and ACVR2 showed frameshift mutations. Among 10 clinical SBA samples, 2 (20%) had interstitial deletions in ?-catenin, expression of mismatch repair protein was aberrant in 4 (40%), and heterozygous frameshift mutations of three target genes were found in all 10 samples. On screening assay using 140 compounds, eribulin significantly inhibited SIAC1 cell growth both in vitro and in vivo by inhibition of the Wnt/?-catenin pathway via enhanced degradation of ?-catenin. In conclusion, we established an SBA cell line with molecular characteristics similar to those of clinical SBA samples, including ?-catenin deletion and mismatch repair protein deficiency, that will be useful for SBA research. Eribulin might be a candidate for SBA treatment due to its inhibitory effect on Wnt/?-catenin signaling. PMID:25478808

  2. Developing a new measure of small bowel peristalsis with dynamic MR: a proof of concept study

    International Nuclear Information System (INIS)

    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 MRynamic MR

  3. Non-emergency small bowel obstruction: assessment of CT findings that predict need for surgery

    International Nuclear Information System (INIS)

    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.)

    To determine the most helpful abdominal CT findings in patients with small bowel perforation without pneumoperitoneum or oral contrast leakage after blunt trauma. We retrospectively analyzed the abdominal CT findings of 51 patients with small bowel perforation without pneumoperitoneum or oral contrast leakage. A score of 2 was assigned if bowel wall thickening of more than 5 mm or enhancement of the bowel wall was definite, and 1 if equivocal thickenting or enhancement of the bowel wall, mesenteric infiltration, sentinel clotting, intermesenteric fluid, or ileus were observed. According to the score, each finding was classified as strongly positive(5-8), possibly positive(3-4), or probably negative(1-2), and the accuracy of each classification was evaluated. We decided which findings would be most helpful when attempting to diagnose small bowel perforation. Forty one bowel perforations and four mesenteric injuries were identified in 45 laparatomies among 51 patients. In all 20 patents with a score of more than 5, small bowel perforation was found on surgery. The prevalence rate of bowel wall thickening and enhancement was significantly different between patients with perforation(88%, 80% respectively) and those without (20%, 40% respectively)(p<0.05). The sensitivity, specificity and accuracy of each criterion were compared (sum of scoring of all CT findings{>=}3D3:82.9% {center_dot} 40% {center_dot} 74.5%;scoring of bowel wall thickening and enhancement {>=}3D 2:82.9% {center_dot} 80% {center_dot} 82.4%), and it was found that for specificity and accuracy, the latter was superior to the former. ROC analysis using the scores of each criterion as cut-off value also showed that the curve of the latter showed a more marked upward trend and was the most helpful parameter. When diagnosing small bowel perforation in the absence of pneumoperitonemum or oral contrast leakage after blunt abdominal trauma, bowel wall thickening and enhancement were more helpful parameters than the sum of all CT findings.=20.

  8. 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 shoen 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

  9. 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 sequencesn bSSFP sequences

    1989-01-01

    Liver needle biopsies from patients with non-A, non-B chronic active hepatitis and so-called abnormal bile duct epithelium were studied with a three-dimensional method. Photographs of bile duct structures in serial sections were transferred to acrylic plates. Five bile duct lesions of a not previously described diverticular type were revealed. The diverticuli were of varying shape with a diameter of 30 to 110 microns and a length of 75 to 150 microns budding from small (12 to 25 microns), slightly ectatic bile ducts. The diverticular epithelium was disordered. Some cells appeared as bile duct cells, but most were larger, with rounded nuclei, prominent nucleoli and abundant eosinophilic cytoplasm, sometimes with periodic acid-Schiff-positive, diastase-resistant granules. The lesions were only partly surrounded by a basement membrane. They were all embedded in a tight mononuclear inflammatory infiltrate associated with pronounced periportal piecemeal necrosis. In two cases, a germinal center was adjacent to the epithelium. The pathogenesis of the diverticular bile duct lesion is unknown, but the diverticuli probably represent Hering ducts and groups of periportal liver cells which have escaped the piecemeal necrosis.

    Internal hernia (IH) is a rare cause of small bowel obstruction occurs when there is protrusion of an internal organ into a retroperitoneal fossa or a foramen in the abdominal cavity. IH can be presented with acute or chronic abdominal symptom and discovered by accident in operation field. However, various kinds of imaging modalities often do not provide the assistance to diagnose IH preoperatively, but computed tomography (CT) scan has a high diagnostic accuracy. We report a case of congenital IH in a 6-year-old boy who experienced life threatening shock. CT scan showed large amount of ascites, bowel wall thickening with poor or absent enhancement of the strangulated bowel segment. Surgical exploration was performed immediately and had to undergo over two meters excision of strangulated small bowel. To prevent the delay in the diagnosis of IH, we should early use of the CT scan and take urgent operation. PMID:24224153

    We report an atypical case of small bowel obstruction 10 days after the repair of an inguinal hernia that had been recurrently reduced. A preoperative diagnosis of the rare intestinal stenosis of Garre is difficult, and was based on the clinical, operative and pathological findings. Forced reduction of a hernia is not recommended because of the risk of rendering its contents ischaemic with subsequent fibrotic stenosis, or reducing a strangulated bowel into the abdominal cavity with subsequent perforation and peritonitis.

    The case history of a patient who developed chylous ascites following abdominal radiotherapy for recurrent carcinoma of the colon was presented. Laparotomy revealed generalized radiation damage of the small bowel with a particularly severely affected segment of jejunum, from the serosal surface of which chyle was seen to be leaking. Mesenteric lymphangiography revealed an obstruction to lymphatic drainage in the mesentery. Resection of the worst affected segment of bowel prevented further development of chylous ascites.

    Objective: The purpose of this study was to assess the frequency of isolated small bowel dilatation on abdominal radiographs in patients with colonic fecal impaction and also to elucidate the cause of this finding. Methods: A computerized search of radiology files revealed 515 patients with colonic fecal impaction on abdominal radiographs. The radiologic reports described isolated small bowel dilatation not related to other known causes of ileus or obstruction in 18 (3.5%) of the 515 patients. The films were reviewed to determine the distribution of fecal impaction and the degree and extent of small bowel dilatation. In 16 cases, medical records were reviewed to determine the clinical presentation, treatment, and course. Finally, follow-up radiographs were reviewed in four cases to determine the response to treatment of the impaction. Results: All 16 patients with available medical records had abdominal symptoms. The average diameter of the dilated small bowel on abdominal radiographs was 3.7 cm. Fourteen patients (78%) had a diffuse colonic fecal impaction (nine) or a predominantly right-sided fecal impaction (five) that involved the cecum, and the remaining four (22%) had a left-sided colonic fecal impaction. All 12 patients with clinical follow-up had resolution of symptoms and all four with follow-up radiographs had resolution of small bowel dilatation after treatment of the underlying impaction. Conclusion: Fecal impaction should be considered in the differential diagnosis of small bowel dilatation on abdominal radiographs, as treatment of the underlying impaction usually produces a dramatic clinical response with resolution of the small bowel dilatation on follow-up radiographs.

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

  18. Use of methylcellulose in small-bowel follow-through examination : comparison with enteroclysis and conventional series in normal subjects

    International Nuclear Information System (INIS)

    To evaluate the efficacy of a modified small bowel follow-through (SBFT) and to optimize this technique. Ninety-nine subjects without small bowel pathology underwent modified SBFT using oral administration of methylcellulose after taking 100ml of 120% or 100, 150, or 200ml of 70% barium. Thirty-three and 39 normal subjects undergoing enteroclysis or conventional SBFT, respectively, were also evaluated for comparison of image qualities and transit time. Enteroclysis was the most successful of three types of small bowel examination for obtaining the best quality of bowel transradiency and distension. Modified SBFT was, however much superior to the conventional series for obtaining good bowel transradiency and rapid transit time (mean, 37-49 minutes). The use of 150ml of 70% barium was better than the other three modified techniques in achieving good bowel transradiency, rapid transit time, and less flocculaton. Our modified SBFT is a simple and safe method for easily improving bowel transradiency and transit time

    Purpose: To determine whether volumes based on contours of the peritoneal space can be used instead of individual small bowel loops to predict for grade ?3 acute small bowel toxicity in patients with rectal cancer treated with neoadjuvant chemoradiation therapy. Methods and Materials: A standardized contouring method was developed for the peritoneal space and retrospectively applied to the radiation treatment plans of 67 patients treated with neoadjuvant chemoradiation therapy for rectal cancer. Dose-volume histogram (DVH) data were extracted and analyzed against patient toxicity. Receiver operating characteristic analysis and logistic regression were carried out for both contouring methods. Results: Grade ?3 small bowel toxicity occurred in 16% (11/67) of patients in the study. A highly significant dose-volume relationship between small bowel irradiation and acute small bowel toxicity was supported by the use of both small bowel loop and peritoneal space contouring techniques. Receiver operating characteristic analysis demonstrated that, for both contouring methods, the greatest sensitivity for predicting toxicity was associated with the volume receiving between 15 and 25 Gy. Conclusion: DVH analysis of peritoneal space volumes accurately predicts grade ?3 small bowel toxicity in patients with rectal cancer receiving neoadjuvant chemoradiation therapy, suggesting that the contours of the peritoneal space provide a reasonable surrogate for the contours of individual small bowel loops. The study finds that a small bowel V15 less than 275 cc and a peritoneal space V15 less than 830 cc are associated with a less than 10% risk of grade ?3 acute toxicity.

    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.)

  1. 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

  2. A survived case of tardive small bowel injury resulting from radiotherapy for ovarial tumor

    International Nuclear Information System (INIS)

    In a patient who underwent surgical excision of recurrent tumor of ovarian disgerminoma, small bowel injury following radiotherapy was treated by extensive excision of the small intestine followed by intravenous hyperalimentation (I.V.H.) and hyperbaric oxygen therapy. From its clinical course and treatment, we concluded that 1) In small bowel complication due to radiation injury, especially perforation of the small bowel, radical excision of the diseased segment is most promising, if the general and local conditions permit. 2) I.V.H. is effective for protecting and improving postoperative malnutrition after extensive excision of the small bowel. 3) Hyperbaric oxygen therapy is very effective for postoperative paralytic ileus in the case in which surgical operation cannot be performed. 4) Zinc deficiency as a complication of prolonged I.V.H. therapy must be protected. 5) It is necessary to study pathophysiology of short bowel syndrome following the extensive excision and to continue treatment and careful long-term follow-up.

    Background Bone marrow mesenchymal stem cells (BMMSCs) have shown immunosuppressive activity in transplantation. This study was designed to determine whether BMMSCs could improve outcomes of small bowel transplantation in rats. Methods Heterotopic small bowel transplantation was performed from Brown Norway to Lewis rats, followed by infusion of BMMSCs through the superficial dorsal veins of the penis. Controls included rats infused with normal saline (allogeneic control), isogeneically transplanted rats (BN-BN) and nontransplanted animals. The animals were sacrificed after 1, 5, 7 or 10 days. Small bowel histology and apoptosis, cytokine concentrations in serum and intestinal grafts, and numbers of T regulatory (Treg) cells were assessed at each time point. Results Acute cellular rejection occurred soon after transplantation and became aggravated over time in the allogeneic control rats, with increase in apoptosis, inflammatory response, and T helper (Th)1/Th2 and Th17/Treg-related cytokines. BMMSCs significantly attenuated acute cellular rejection, reduced apoptosis and suppressed the concentrations of interleukin (IL)-2, IL-6, IL-17, IL-23, tumor necrosis factor (TNF)-?, and interferon (IFN)-? while upregulating IL-10 and transforming growth factor (TGF)-? expression and increasing Treg levels. Conclusion BMMSCs improve the outcomes of allogeneic small bowel transplantation by attenuating the inflammatory response and acute cellular rejection. Treatment with BMMSCs may overcome acute cellular rejection in small bowel transplantation. PMID:25500836

    Transmesenteric hernias are extremely rare. A strangulated hernia through a mesenteric opening is a rare operative finding. Preoperative diagnosis still is difficult in spite of the imaging techniques currently available. The authors describe two cases of paediatric patients presenting with bowel obstruction resulting from a congenital mesenteric hernia. The first patient had a 3-cm wide congenital defect in the ileal mesentery through which the sigmoid colon had herniated. The second patient...

  5. Contrast radiography in small bowel obstruction. A randomized trial of barium sulfate and a nonionic low-osmolar contrast medium

    International Nuclear Information System (INIS)

    Thirty-six adult patients clinically suspected of small bowel obstruction underwent small bowel contrast radiography with either barium sulfate or a nonionic low-osmolar contrast medium after randomization. Films were taken after 2, 4, and 8 hours and later when needed. No difference as regards visualization and diagnostic quality was found between the 2 media. It is concluded that a nonionic low-osmolar contrast medium is an alternative to barium sulfate for small bowel contrast radiography where small bowel obstruction is suspected. (orig.)

  6. CT findings in acute small bowel diverticulitis; Computertomographie bei akuter Duenndarmdivertikulitis

    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.

    2011-05-01

    Full Text Available Introduction: The purpose of our study was to describe the evaluation and outcome of patients with ileus and bowel obstruction admitted to an emergency department (ED observation unit (OU and to identify predictors of successful management for such patients. Methods: We performed a retrospective chart review of 129 patients admitted to a university-affiliated, urban, tertiary hospital ED OU from January 1999 through November 2004. Inclusion criteria were all adult patients admitted to the OU with an ED diagnosis of ileus, partial small bowel obstruction, or small bowel obstruction, and electronic medical records available for review. The following variables were examined: ED diagnosis, history of similar admission, number of prior abdominal surgeries, surgery in the month before, administration of opioid analgesia at any time after presentation, radiographs demonstrating air–fluid levels or dilated loops of small bowel, hypokalemia, use of nasogastric decompression, and surgical consultation. Results: Treatment failure, defined as hospital admission from the OU, occurred in 65 (50.4% of 129 patients. Only the use of a nasogastric tube was associated with OU failure (21% discharged versus 79% requiring admission, P ¼ 0.0004; odds ratio, 5.294; confidence interval, 1.982–14.14. Conclusion: Half of the patients admitted to our ED OU with ileus or varying degrees of small bowel obstruction required hospital admission. The requirement of a nasogastric tube in such patients was associated with a greater rate of observation unit failure. [West J Emerg Med. 2011;12(4:404–407.

  9. 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

  10. The use of a biodegradable mesh to prevent radiation-associated small-bowel injury

    International Nuclear Information System (INIS)

    Radiation-associated small bowel injury occurs in up to 50% of patients receiving postoperative radiotherapy following pelvic cancer surgery. We describe our experience using a biodegradable mesh that allows the small bowel to be supported above the pelvic inlet and is totally absorbed following radiation therapy. Between 1985 and 1989, 45 procedures were performed in patients with carcinoma of the rectum (anterior resection in 15 patients, abdominoperineal resection in 23 patients, pelvic exenteration in six patients, and proctocolectomy in one patient). In 30 patients a polyglycolic acid (Dexon) mesh was used, and in 15 patients a polyglactin 910 (Vicryl) mesh was used. Forty-four patients received postoperative radiotherapy. The mean (+/- SEM) dose was 56.8 +/- 18.4 Gy. There were no immediate complications related to the mesh. Follow-up ranged from 12 to 53 months (median follow-up, 34 months). With the exception of two patients who had a polyglactin 910 mesh and who developed bowel obstruction due to adhesions under the anterior abdominal wall, there has been no documented incidence of clinical radiation-associated small bowel injury. The use of the absorbable mesh may permit us to use higher doses of postoperative radiotherapy without the associated hazard of radiation-associated small bowel injury

    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.

    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.

    Spontaneous intramural haemorrhage is a rare cause of small-bowel obstruction, occurring most commonly in those who are anticoagulated. We describe two cases that presented with a history and imaging suggestive of small-bowel obstruction; both had International Normalized Ratios of above 10 on admission. The first case, a 62-year-old lady on warfarin for atrial fibrillation, was managed conservatively with good effect. In contrast, the second case, a 57-year-old gentleman on warfarin for his metallic aortic valve, underwent diagnostic laparotomy that revealed a 30-cm segment of proximal jejunum with spontaneous intramural haemorrhage. In this study, we emphasize the merit of conservative management for this rare cause of small-bowel obstruction. PMID:25858268

    Recent evidence suggests that bombesin (BBS) is involved in modulation of growth and differentiation of normal small intestine. The purpose of the present study was to evaluate the effects of BBS on enterocyte turnover after massive small bowel resection in a rat. Male Sprague-Dawley rats were divided into three experimental groups: Sham rats underwent bowel transection and re-anastomosis, short bowel syndrome (SBS) rats underwent a 75% small bowel resection, and SBS-BBS rats underwent bowel resection and were treated with BBS given subcutaneously at a dose of 20 mug/kg, once daily, from postoperative day 3 through 14. Parameters of intestinal adaptation (bowel and mucosal weights, mucosal DNA and protein, villus height and crypt depth), enterocyte proliferation and enterocyte apoptosis were determined in jejunum and ileum on day 15 following operation. RT-PCR technique was used to determine Bax and Bcl-2 gene expression in ileal mucosa. Statistical analysis was performed using the non-parametric Kruskal-Wallis ANOVA test, with P less than 0.05 considered statistically significant. Treatment with BBS resulted in a significant increase in ileal bowel and mucosal weight, ileal mucosal DNA and protein, jejunal and ileal villus height, jejunal crypt depth, and jejunal and ileal proliferation index compared to SBS-animals. SBS rats showed a significant increase in Bax and Bcl-2 expression in ileum that was accompanied by a significant increase in cell apoptosis compared to sham animals. SBS-BBS rats demonstrated a significant decrease in Bax and Bcl-2 expression in ileum and a decrease in apoptotic index compared to SBS-animals. In conclusion, in a rat model of SBS, BBS enhances enterocyte turnover and stimulates structural intestinal adaptation. Decreased Bax expression may be responsible for the inhibitory effect of BBS on enterocyte apoptosis. PMID:17440764

  19. Alterations in myoelectric activity of the small bowel in rabbits after transarterial embolization

    International Nuclear Information System (INIS)

    Objective: To explore alterations in myoelectric activity of the small bowel in rabbits after transarterial embolization and provide academic basis for assessing bowel viability and management. Methods: Twenty normal rabbits were selected and divided into three groups (2 mg group, n=10; 6 mg group, n=5; control group, n=5). Members of 2 mg group were embolized with PVA 2 mg, those of 6 mg group with PVA 6 mg, and the control group with normal saline 2 ml. After microcatherization embolization, myoelectric activity of the small bowel was recorded for 24 hr using chronically implanted electrodes in conscious rabbits. Results: In 2 mg group, the frequency and the amplitude of slow wave of proximal jejunum were significantly lower in post-embolization period than pre-embolization period [(17.83±0.55) cpm vs (11.59±0.23) cpm(P0.05) and (0.1632±0.002) mV vs (0.1606±0.003) mV (P>0.05), respectively]. ConclumV (P>0.05), respectively]. Conclusions: Embolization with PVA evokes significant and passive effect on basal electrical rhythm of small bowel. It could provide academic basis for assessing bowel viability to interventional embolization. (authors)

    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.

    Extramedullary plasmacytoma is a rare disease that is histopathologically defined as a solitary tumor composed of a monoclonal proliferation of cells with plasmacytic differentiation in an extramedullary site. Most of these tumors occur in the submucosa of the upper aerodigestive tract, and they rarely occur in the small bowel mesentery. We report here on a case of extramedullary plasmacytoma of the small bowel mesentery that was in association with a cecal cancer. Abdominal ultrasound and CT revealed a lobulated soft tissue mass with a cystic portion and peripheral calcification. In this case, the preoperative radiological diagnosis was difficult due to accompanying cecal cancer.

    The radiologic findings on small bowel enema examination using barium and methylcellulose (SBE+Ba+MC) in a patient with Whipple's disease before and after treatment are described. The changes on SBE+Ba+MC corresponded well to the clinical and morphologic picture. The advantages of this double contrast technique compared to the enteroclysis with barium alone are demonstrated. The SBE+Ba+MC is a good method to demonstrate the manifestations of Whipple's disease involving the small bowel and the mesentery.

  4. Small bowel exclusion from the pelvis by a polyglycolic acid mesh sling

    International Nuclear Information System (INIS)

    Radiation enteritis is seen in patients receiving radiation therapy for various pelvic malignancies. Attempts to prevent this have included various surgical as well as nutritional approaches with little success. The use of a polyglycolic acid mesh sling sewn above the pelvic inlet has prevented small bowel descent into the true pelvis in rats and in humans. The technique has been successful in both with no attendant morbidity during an 11-month follow up. Several patients have received additional doses of radiation therapy that would not have been given if the small bowel were not removed from the area to be irradiated

    This case report describes an extremely rare cause of small bowel obstruction. A female patient who was liver transplanted seven years earlier and had been in immunosuppressive therapy since then presented with clinical and radiological manifest small bowel obstruction and surgery followed. The surgical finding was a segment near the terminal ileum with three separate stenoses in which the most oral was causing the obstruction. Histology evaluation of the stenoses revealed infiltration of lymphoid tissue and the stenoses tested positive on Epstein-Barr virus. The patient was later confirmed to be suffering from post-transplant lymphoproliferative disease. PMID:25354009

    Intestinal lipomatosis is a rare disease with an incidence at autopsy ranging from 0.04% to 4.5%. Because the lipomas are diffusely distributed in the intestine, most patients are symptom-free, and invasive intervention is not advised by most doctors. Here, we describe a case with intussusception due to small-bowel lipomatosis. Partial small bowel resection and anastomosis were performed because the intestinal wall was on the verge of perforation. This case indicates that regular follow-up is necessary and endoscopic treatment should be considered to avoid surgical procedures if the lipoma is large enough to cause intestinal obstruction.

    Full Text Available Complicated small-bowel diverticulosis is a rather uncommon cause of upper abdominal pain. It may lead to symptoms presenting with an acute onset or to chronic and nonspecific complaints. As the presentation is often similar to other pathologies (acute appendicitis, pancreatitis, or acute cholecystis and in many cases diagnosis is made on basis of surgical findings, careful analysis of the imaging landmarks may be warranted to aid in the early stages of detection. In this report, we present clinical and morphological findings in three patients where small-bowel diverticulitis was surgically proven. The relevant literature is reviewed, and typical imaging properties are discussed.

    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

    Four children who underwent ABO-compatible combined liver and small bowel transplantation developed severe immune-mediated hemolytic anemia. The main management strategies were early and aggressive treatment with steroids, the introduction of rituximab (an anti-CD20 monoclonal antibody), and the use of plasma exchange together with compatible but minimal blood transfusions. Three of the 4 children developed thrombi in the major vessels. In small bowel transplant patients, the early recognition of hemolytic anemia and intensified management with anticoagulation are necessary for the prevention of this complication. PMID:21472974

  16. Decreasing gastrointestinal morbidity with the use of small bowel contrast during treatment planning for pelvic irradiation

    International Nuclear Information System (INIS)

    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 fiel 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

    2012-05-01

    Full Text Available Abstract Introduction Perforation caused by capsule endoscopy impaction is extremely rare and, at present, only five cases of perforation from capsule endoscopy impaction are reported in the literature. Case presentation We report here two cases of patients with undiagnosed small bowel stenosis presenting with acute perforation after capsule endoscopy. Strictures in the small bowel were likely the inciting mechanism leading to acute small bowel obstruction and subsequent distension and perforation above the capsule in the area of maximal serosal tension. Case 1 was a 55-year-old Italian woman who underwent capsule endoscopy because of recurrent postprandial cramping pain and iron deficiency anemia, in the setting of negative imaging studies including an abdominal ultrasound, upper endoscopy, colonoscopy and small bowel follow-through radiograph. She developed a symptomatic bowel obstruction approximately 36 hours after ingestion of the capsule. Emergent surgery was performed to remove the capsule, which was impacted at a stenosis due to a previously undiagnosed ileal adenocarcinoma, leading to perforation. Case 2 was a 60-year-old Italian man with recurrent episodes of abdominal pain and diarrhea who underwent capsule endoscopy after conventional modalities, including comprehensive blood and stool studies, computed tomography, an abdominal ultrasound, upper endoscopy, colonoscopy, barium enema and small bowel follow-through, were not diagnostic. Our patient developed abdominal distension, acute periumbilical pain, fever and leukocytosis 20 hours after capsule ingestion. Emergent surgery was performed to remove the capsule, which was impacted at a previously undiagnosed ileal Crohn’s stricture, leading to perforation. Conclusions The present report shows that, although the risk of acute complication is very low, the patient should be informed of the risks involved in capsule endoscopy, including the need for emergency surgical exploration.

    Tension-free vaginal tape (TVT) is commonly considered as the first line of treatment for stress urinary incontinence (SUI) with demonstrated efficacy and limited complications. An 82-year-old woman with complete uterine procidentia and SUI underwent a Le Forte colpocleisis, TVT, posterior repair, and cystoscopy. A 4-cm bulge was noted over the site of the left TVT incision on postoperative day 1. On postoperative day 3, she developed bilious vomiting with slight abdominal distention. Computed tomography scan showed a strangulated left inguinal hernia. An immediate exploratory laparotomy noted an inguinal hernia displaced medially with loops of small bowel in the hernia sac. Although properly positioned, one loop of bowel was perforated by the sling mesh. A small bowel resection was performed and the mesh trimmed below the resection on involved side. At 2 months postoperative visit, the patient was asymptomatic, denied stress or urge incontinence. Vaginal examination noted well-supported vaginal walls. PMID:19641837

    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

  2. Dislocation of small bowel volume within box pelvic treatment fields, using new 'up down table' device

    International Nuclear Information System (INIS)

    Purpose: To present the impact of a novel minimization device, the up down table (UDT), on the volume of small bowel included within a 4-field pelvic irradiation plan. Methods: A polystyrene bowel displacement standard mold was created and added to a customized vacuum cushion (Vac Lok) formed around the abdomen and legs of each patient in the prone position. Two hundred seventy-seven consecutive patients with pelvic malignancies treated with the UDT device were compared with 1 historic series (68 cases) treated at our division. Small bowel contrast dyes at the time of simulation were used in all patients. Results: The average volume of small bowel within the planning target volume (high-dose volume, calculated with Gallagher method) was 100 cm3 (median 49±114) in the series treated with standard box technique and 23 cm3 (median 0±64) in the series treated with the UDT (p3 (median 447±338) and 158 cm3 (median 69±207), respectively (p<0.001). The incidence of G1, G2, and G3 acute enteric toxicity (Radiation Therapy Oncology Group criteria) in the UDT series was 16%, 15%, and 1.5%; in the standard box technique, it was 28%, 25%, and 3%, respectively (p<0.05). The incidence of acute enteric toxicity directly correlated with the irradiated small bowel volume. In the UDT series, the 5-year actuarial incidence of G3 chronic enteric toial incidence of G3 chronic enteric toxicity was 1.8%. The setup procedures, analyzed in 18 cases, revealed no systematic errors and a standard deviation equal to ±5 mm for random errors. Conclusions: The UDT technique is comfortable, inexpensive, highly reproducible, and permits an almost full bowel displacement from standard radiotherapy fields

    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 interventio000.

    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.

    We report the case of a 59-year-old Afro-Caribbean woman who presented with symptoms of anorexia, lethargy, abdominal distension and vomiting on the background of newly diagnosed multiple myeloma, treated with one cycle of cyclophosphamide-thalidomide-dexamethasone chemotherapy 20 days previously. A diagnosis of subacute bowel obstruction was made; however, the aetiology of the obstruction remained elusive. Common electrolyte abnormalities were excluded and a midline laparotomy revealed minimal intra-abdominal adhesions. Histological examination of a small bowel mesentery biopsy showed inflammatory cell infiltrate composed of lymphocytes, eosinophils and occasional plasma cells with a foreign body giant cell reaction suggestive of worm infection. A postoperative stool sample revealed heavy infestation with the rhabditiform larvae of Strongyloides stercoralis. The patient recovered following ivermectin treatment. In the absence of other causality, we attribute the subacute bowel obstruction to S stercoralis hyperinfection, triggered by immunosuppression secondary to chemotherapy and multiple myeloma.

  11. Small and large bowel volvulus: Clues to early recognition and complications

    International Nuclear Information System (INIS)

    Small and large bowel volvulus are uncommon causes of bowel obstruction with nonspecific clinical manifestations which may delay the diagnosis and increase morbidity. Therefore, radiologists play an important role in promptly establishing the diagnosis, recognizing underlying congenital or acquired risk factors and detecting potentially life-threatening complications. Multidetector CT performed with intravenous contrast is currently the preferred modality for the evaluation of volvulus, which is best appreciated when imaging is perpendicular to the axis of bowel rotation, hence the benefit of multiplanar reformations. In this pictorial essay we review the pathophysiology of the different types of intestinal volvulus, discuss diagnostic criteria for prompt diagnosis of volvulus and emphasize early recognition of the complications.

    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.

    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.

    Numerous cytokines have been shown to affect epithelial cell differentiation and proliferation through epithelial-mesenchymal interaction. Growing evidence suggests that platelet-derived growth factor (PDGF) signaling is an important mediator of these interactions. The purpose of this study was to evaluate the effect of PDGF-? on enterocyte turnover in a rat model of short bowel syndrome (SBS). Male rats were divided into four groups: Sham rats underwent bowel transection, Sham-PDGF-? rats underwent bowel transection and were treated with PDGF-?, SBS rats underwent a 75% bowel resection, and SBS-PDGF-? rats underwent bowel resection and were treated with PDGF-?. Parameters of intestinal adaptation, enterocyte proliferation and apoptosis were determined at euthanasia. Illumina's Digital Gene Expression analysis was used to determine PDGF-related gene expression profiling. PDGF-? and PDGF-? receptor (PDGFR-?) expression was determined by real-time PCR. Western blotting was used to determine p-ERK, Akt1/2/3, bax, and bcl-2 protein levels. SBS rats demonstrated a significant increase in PDGF-? and PDGFR-? expression in jejunum and ileum compared with sham animals. SBS-PDGF-? rats demonstrated a significant increase in bowel and mucosal weight, villus height, and crypt depth in jejunum and ileum compared with SBS animals. PDGF-? receptor expression in crypts increased in SBS rats (vs. sham) and was accompanied by an increased cell proliferation following PDGF-? administration. A significant decrease in cell apoptosis in this group was correlated with lower bax protein levels. In conclusion, in a rat model of SBS, PDGF-? stimulates enterocyte turnover, which is correlated with upregulated PDGF-? receptor expression in the remaining small intestine. PMID:22461028

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

    International Nuclear Information System (INIS)

    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.

  2. Effect of viscous fiber (guar) on postprandial motor activity in human small bowel.

    Schönfeld, J; Evans, D F; Wingate, D L

    1997-08-01

    Both caloric value and chemical composition of a meal have been shown to regulate postprandial small bowel motility in dog. In the same species, duration of and contractile activity within the postprandial period also depends on mean viscosity. It is unknown, however, whether meal viscosity and fiber content also regulate small bowel motor activity in man. In human volunteers, we therefore studied the effect of guar gum on small bowel motor response to liquid and solid meals. Twenty-six prolonged ambulatory small bowel manometry studies were performed in 12 volunteers. A total of 620 hr of recording were analyzed visually for phase III of the MMC and a validated computer program calculated the incidence and amplitude of contractions after ingestion of water (300 ml), a pure glucose drink (300 ml/330 kcal) or a solid meal (530 kcal) with and without 5 g of guar gum. Addition of 5 g of guar gum did not significantly delay reappearance of phase III after ingestion of water (59 +/- 11 vs 106 +/- 21 min; P = 0.09). However, guar gum significantly prolonged duration of postprandial motility pattern both after the glucose drink (123 +/- 19 vs 199 +/- 24 min; P meal (310 +/- 92 vs 419 +/- 22 min; P = 0.005). Contractile activity during these periods was not affected by guar gum. This was true for mean incidence of contractions after water (1.9 +/- 0.3 vs 1.8 +/- 0.5 min-1), after the glucose drink (1.6 +/- 0.4 vs. 1.7 +/- 0.3 min-1) and after the solid meal (2.4 +/- 0.4 vs 2.6 +/- 0.4 min-1). Likewise, mean amplitude of contractions was not affected by guar gum after water (22.8 +/- 1.4 vs 20.9 +/- 1.9 mm Hg), after the glucose drink (20.5 +/- 1.4 vs 21.3 +/- 1.2), and after the solid meal (20.3 +/- 1.5 vs 21.5 +/- 1.6 mm Hg). Thus a guar gum-induced increase in chyme viscosity markedly prolonged duration of postprandial motor activity in the human small bowel. Contractile activity within the postprandial period, however, was not affected. We suggest that the postprandial motility pattern persisted longer after the more viscous meals, because gastric emptying and intestinal transit were delayed by guar gum. We conclude that it is essential to define meal viscosity and fiber contents when studying postprandial small bowel motility. PMID:9286225

  3. Pathological and clinical significance of increased intraepithelial lymphocytes (IELs) in small bowel mucosa.

    Chang, Fuju; Mahadeva, Ula; Deere, Harriet

    2005-06-01

    Intestinal intraepithelial lymphocytes (IELs) belong to a unique T-cell population interspersed between epithelial cells of both the small and large intestine. It is becoming increasingly recognised that an increased number of IELs with a normal villous architecture is within the wide spectrum of histological abnormalities observed in coeliac disease. An increased number of IELs is the earliest pathological change following gluten challenge and a high IEL count may be the only sign of gluten sensitivity. Therefore, the finding of a raised IEL count with normal villous architecture is of sufficient clinical importance to be reported in routine small bowel biopsies. However, it is evident that not all small intestinal biopsy specimens showing increased IELs are explained by gluten sensitivity. Increased IELs in small bowel mucosa have also been associated with autoimmune disorders, tropical sprue, food protein intolerance, Helicobacter pylori-associated gastritis, peptic duodenitis, parasitic and viral infections, as well as the development of intestinal lymphoma. Histological examination of a biopsy specimen of the small bowel remains the diagnostic gold standard for coeliac disease. There will be an ever increasing demand for histological confirmation of gluten sensitivity in patients in whom the classic microscopic appearance of flattened villi may not have fully developed. The more widespread recognition by histopathologists of the pattern of injury manifested by increased numbers of IELs in intestinal biopsy specimens will certainly help in early diagnosis of coeliac disease, lessen diagnostic confusion and influence the modern practice of gastrointestinal tract medicine. This review discusses some of the recent developments in clinical pathology pertaining to increased IELs in small bowel mucosal biopsies. PMID:15996156

  4. 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.

  5. Efficacy and efficiency of small bowel double contrast enema

    International Nuclear Information System (INIS)

    The double contrast examination is the most effective morphological screening method for the evaluation of the whole small intestine. Its sensitivity is 85%, its specifity 96.7%. In specific clinical problems the number of pathological roentgen rises: from 34,4% when all indications are taken into consideration to 58% in indications specific to the small intestine such as Morbus Crohn or the malabsorption syndrome. Search for tumors and the double contrast of the small intestine in unclear gastro-intestinal bleeding are unproductive. The weak point of this screening method is the lower part of the small intestine. Therefore, the selective peroral or retrograde analysis of the terminal ileum supplement the contrast method. A precondition for good results is an adequate technical standard. Besides the clinical results some technical results are therefore discussed such as contrast medium quantities, examination and X-ray time, radiation exposure and influences on the image quality.

    Small bowel angioedema is a rare adverse effect of iodinated contrast medium. Here, we report the first case of contrast medium-induced small bowel angioedema with concurrent respiratory tract symptoms. A patient with colon cancer underwent CT scanning for preoperative staging. After injection of the contrast medium, a persistent cough developed and CT images showed that the small bowel wall was abnormally thickened. It returned to normal by the follow-up. The persistent coughing that developed right after the CT and small bowel wall thickening on the contrast-enhanced CT suggested the diagnosis of small bowel angioedema induced by the contrast medium.

  7. Bariumexaminations of the small intestine and the colon in inflammatory bowel disease

    International Nuclear Information System (INIS)

    This article gives an overview of the possibilities of conventional radiography in the diagnosis of inflammatory bowel disease of the small intestine and colon.Material and methods For more than 25 years we examine the small bowel employing enteroclysis with barium and methylcellulose and the colon with the usual double-contrast method. In the last 152 months 1560 small bowel enemas were performed. In the last 40 months 410 examinations of the colon were performed. There is a thirty percent decrease in enteroclysis examinations within the past 5 years,however, the rate of examinations with positive results increased from 46 to 57%.The proportion of the inflammatory small intestinal diseases (not only Crohn's disease) remained constant with 18%.Concerning the examinations of the colon for inflammatory disease we confirmed the diagnosis in seven cases.The radiation exposure for the enteroclysis in inflammatory diseases was 7mSv, for colon examinations 14 mSv. Barium examinations, especially of the stomach and colon are decreasing in frequency.Therefore the art of performance and interpretation might get lost.Enteroclysis, however, is still the method of reference for the other imaging methods.The advantages compared to the other imaging methods are the excellent presentation of the details of the mucosal surface and the observation of functional disorders.

  8. 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.)

    Fasting small intestine motility (migrating motor complex or MMC) occurs in humans and dogs in four phases. Activity fronts during phase III consist of high amplitude contractions propagating aborally and are interrupted by transection of the small intestine. To study the effect of anastomosis type on MMC propagation six dogs underwent resection of a 15-cm segment of bowel 45 cm distal to the ligament of Treitz and single layer hand sewn end-to-end (EE) anastomosis. Single layer end-to-side (ES) or side-to-side (SS) anastomoses were hand sewn 15 cm distal to the transection in six other dogs. Eight force transducer strain gauges were placed at 10-cm intervals about each anastomosis. At least 7 days after operation, small bowel contractions were recorded in fasted animals, and recordings were visually inspected. Only 1 of 36 activity fronts propagated across the end-to-end anastomosis within 45 days of surgery. However, after 60 days 25 of 39 phase III activity fronts propagated. There was no propagation of MMC activity across the ES anastomosis and only 10% of activity fronts propagated across the SS anastomosis. We conclude phase III MMC activity front propagation is interrupted by small bowel transection. Propagation regenerates after EE anastomosis, but not after ES or after SS anastomoses, even after prolonged healing. PMID:1943088

    2009-01-01

    Full Text Available Bezoars represent the fifth most frequent cause of acute small bowel obstruction. Phytobezoar is the most common type of bezoar. It is a concretion of undigestible fibers derived from ingested vegetables and fruits. We report a case of a woman with a 1-year history of recurrent epigastric and periumbilical abdominal pain with intermittent vomiting caused by phytobezoar of the terminal ileum. After careful investigation of the case and review of literature, we identified the factor involved in bezoar formation as radiation-induced ileal stenosis due to previous treatment for a pelvic tumour. This report provides evidence to consider phytobezoar as a possible cause of small bowel obstruction in patients previously treated with abdominal radiotherapy.

    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.

    To recognize and document the small bowel reactions following major abdominal surgery is an important key for a correct diagnosis. Usually, plain abdominal radiography is the initial imaging examination requested in the immediate postoperative period, whereas gastrointestinal contrast studies are used to look for specific complications. In some countries, especially in Europe, sonography is widely employed to evaluate any acute affection of the abdomen. CT is commonly used to assess postoperative abdominal complications; in our institution also CT enteroclysis is often performed, to provide additional important informations. Radiologist should be able to diagnose less common types of obstruction, such as afferent loop, closed loop, strangulating obstruction as well as internal hernia. This knowledge may assume a critical importance for surgeons to decide on therapy. In this article, we focus our attention on the imaging (particularly CT) in small bowel complications following abdominal surgery.

    (Full text is available at http://www.manu.edu.mk/prilozi). Small bowel diverticulosis (SBD) is a rare condition. In most cases it is asymptomatic, but sometimes it can be manifested with chronic non-specific or acute symptoms. Because of the absence of pathognomonic signs and symptoms and truly reliable diagnostic tests, SBD is hard to diagnose and this is usually done incidentally by radiographic examination or during laparatomy. For uncomplicated patients, those with chronic abdominal pain, syndromes of malabsorption related to jejunoileal diverticulosis, bacterial overgrowth or an episodeof intestinal obstruction, as in our case, conservative management is the initial option for treatment. A case of a patient with obstructive symptoms of the gastrointestinal tract due to SBD that was conservatively treated and had a positive outcome is presented. Key words: Small bowel, diverticulosis, ileus, management. PMID:23917752

  16. The localization of bleeding small bowel lesions for conservative resection: a simple radiographic technique

    International Nuclear Information System (INIS)

    Haemorrhage from the small bowel is a serious diagnostic and therapeutic problem. The value of selective superior mesenteric angiography to localize the source accurately does not require emphasizing. However, many of the lesions demonstrated are notoriously difficult to find at operation unless they are actively bleeding at the time. A simple method of intra-operative angiography is described which, because demonstration of the bleeding lesion on the operative films is not an essential requirement, does not involve the use of specialized angiographic equipment. Although only one case is offered to illustrate the method, it seems to possess sufficient versatility to be useful in most situations where intra-operative assistance in isolating a specific loop of small bowel for resection is anticipated.

  17. A case of radiation enteritis with small bowel ulcer causing massive bleeding

    International Nuclear Information System (INIS)

    A 62-year-old female was admitted to our hospital for massive melena. She had been treated with radiation therapy for cervical cancer 4 months earlier. A retrograde double-balloon enteroscopy revealed a small ulcer in the small intestine, and small-bowel series demonstrated a slight stricture in the ulcerative lesion. Although melena was stopped after conservative therapy with blood transfusion, massive melena occurred again one month later. A normograde double-balloon enteroscopy revealed a small ulcer in the small intestine with a medium hemorrhage. Under laparotomy, a small induration was palpated in the small intestine 220 cm proximal to the ileocecal valve, and partial resection was performed. A small ulcer was included in the resected specimen, and histopathological examination demonstrated radiation enteritis with ulcer. The patient was discharged from the hospital 6 days after the operation, and no obvious symptom such as melena was seen at a 6-month follow-up. (author)

    Malignant melanoma is characterized by metastases also to the gastrointestinal tract, especially in the small bowel. The diagnosis is often delayed because unspecific clinical presentation (frequently as chronic iron deficiency anemia, rectal bleeding or intestinal obstruction). We present a case of melanoma of unknown primary site, with clinical presentation of intestinal obstruction. A segmental resection of the ileum was performed including mesentery with lymph nodes. Histology revealed metastatic melanoma from unknown primary. PET and MRI confirmed disseminated disease without brain metastasis. PMID:25419593

    Intestinal adaptation is an important compensatory response to massive small bowel resection (SBR) and occurs because of a proliferative stimulus to crypt enterocytes by poorly understood mechanisms. Recent studies suggest the enteric nervous system (ENS) influences enterocyte proliferation. We, therefore, sought to determine whether ENS dysfunction alters resection-induced adaptation responses.

  8. In vitro allograft irradiation prevents graft-versus-host disease in small-bowel transplantation

    International Nuclear Information System (INIS)

    In small-bowel transplantation, the transfer of large numbers of donor lymphocytes with the intestinal allograft may provoke a lethal graft-versus-host reaction. The effectiveness of allograft irradiation in vitro as a method of preventing graft-versus-host disease (GVHD) was studied in a rat model of small-bowel transplantation, with the Lewis----Lewis X Brown Norway F1 hybrid strain combination. Cold harvested small-bowel allografts were irradiated immediately prior to heterotopic or orthotopic transplantation. Animals that had received heterotopic allografts irradiated with 0, 250, or 500 rad all died of GVHD after 14.4 +/- 3.0, 15.0 +/- 1.3, and 14.2 +/- 1.9 days, respectively. None of the animals that had received allografts treated with 1000 rad developed clinical or pathologic evidence of GVHD, however, and all survived for more than 6 months (P less than 0.001). Allograft function was studied in animals that underwent orthotopic transplantation. Recipients of nonirradiated orthotopic allografts all died of GVHD after 14.0 +/- 0.7 days, whereas recipients of allografts irradiated with 1000 rad all survived for more than 5 months (P less than 0.001). After 120 days, weight gain (51.8 +/- 11.7%), serum albumin (3.9 +/- 0.7 g/dl), serum triglycerides (67.0 +/- 24.3 mg/dl), CBC, and differential in these animals were not statistically different from those in either age-matched isograft recipients or normal animals, and when the rats were sacrificed, irradiated allo the rats were sacrificed, irradiated allografts showed no changes suggestive of radiation injury. These results indicate that irradiation of small-bowel allografts in vitro prevents development of GVHD, and that this can be achieved at a dose which does not cause injury to or malfunction of the allograft

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

    LENUS (Irish Health Repository)

    O'Daly, Brendan J

    2009-06-01

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

    To describe GVHR in small bowel transplantation and its underlying mechanisms and to find methods for circumventing that response, accessory small bowel transplantation was carried out in the rat model. Animals not treated with cyclosporine, irradiation, or removal of the mesenteric lymph nodes of the graft died within 22 days postoperatively due to graft versus host disease. Mesenteric lymph nodes of the graft and recipient spleen and peripheral lymph nodes showed strong immunologic stimulation histologically and high antihost T-cell-mediated cytotoxic antihost reactivity. Seventy-one percent of the animals that had received 15 mg of cyclosporine per kilogram body weight orally survived 150 days after transplantation. After donor irradiation with 50 rads, 77 percent of the recipients survived 120 days. After microsurgical removal of the mesenteric lymph nodes of the graft, 89 percent survived 120 days. We conclude that GVHR plays an important role in small bowel transplantation and that the experimental regimens of donor, graft, and recipient treatment described herein have proved their efficacy for circumventing GVHR.

    2012-07-01

    Full Text Available Spontaneous sublingual hematoma and intramural small bowel hematoma are rare and serious complications of anticoagulant therapy. Though previously reported individually, there has been no previous report of the same two complications occurring in a single patient. A 71-year-old Caucasian man, who was on warfarin for atrial fibrillation, presented with difficulty in swallowing due to a sublingual hematoma. He was observed in our intensive care unit, his warfarin was held and he recovered with conservative management. He represented two months later with a two day history of abdominal pain and distension. An abdominopelvic computed tomography (CT scan now showed small bowel obstruction due to intramural small bowel hematoma and haemorrhagic ascites. Again, this was treated expectantly with a good outcome. In conclusion, life threatening haemorrhagic complications of oral anticoagulant therapy can recur. Conservative treatment is successful in most cases, but an accurate diagnosis is mandatory to avoid unnecessary surgery. CT scan is the investigation of choice for the diagnosis of suspected haemorrhagic complications of over coagulation.

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

    International Nuclear Information System (INIS)

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

    2008-01-01

    Full Text Available We report a 31-year-old woman with Crohn’s disease complicated by multiple stenoses and internal fistulas clinically misdiagnosed as small bowell endometriosis, due to the patient’s perimenstrual symptoms of mechanical subileus for 3 years; at first monthly, but later continuous, and gradually increasing in severity. We performed an exploratory laparotomy for small bowel obstruction, and found multiple ileal strictures and internal enteric fistulas. Because intraoperative findings were thought to indicate Crohn’s disease, a right hemicolectomy and partial distal ileum resection were performed for obstructive Crohn’s ileitis. Histopathology of the resected specimen revealed Crohn’s disease without endometrial tissue. The patient made an uneventful recovery from this procedure and was discharged home 10 d post-operatively. The differential diagnosis of Crohn’s diease with intestinal endometriosis may be difficult pre-operatively. The two entities share many overlapping clinical, radiological and pathological features. Nevertheless, when it is difficult to identify the cause of intestinal obstruction in a woman of child-bearing age with cyclical symptoms suggestive of small bowel endometriosis, Crohn’s disease should be included in the differential diagnosis.

    AIMS: The pneumocolon technique in small bowel meal examination is used to obtain double-contrast views of the distal ileum. The purpose of this study was to determine the proportion of cases in which an overhead pneumocolon radiograph demonstrated clinically relevant findings in the colon. METHODS: The overhead pneumocolon radiographs in 151 patients who underwent small bowel meals were evaluated retrospectively. A chart review was performed on those patients with positive colonic findings to determine if the suspected abnormalities affected patient management. RESULTS: Colonic abnormalities were identified in 34 of the 151 patients. One patient had a previously undiagnosed ascending colonic cancer; 17 had evidence of acute or chronic colitis; 13 had diverticulosis; one had a caecal polyp; one had an ileosigmoid fistula; one had a filling defect in the ascending colon. In 25 cases the colonic abnormality was visible only on the pneumocolon radiograph and not on the preceding single-contrast images. Management was altered by the colonic findings in seven cases. False-positive findings occurred in two cases. CONCLUSIONS: A routine overhead radiograph following use of the pneumocolon technique is a useful adjunct to small bowel meal examination as it can yield unsuspected and clinically significant colonic findings.

    Small intestinal neoplasia is a rare condition that frequently presents a diagnostic challenge. We describe the case of a 70-year-old patient who presented with several years of chronic, intermittent abdominal pain, previously diagnosed as irritable bowel syndrome. Radiographic evaluation, including upper gastrointestinal series with small bowel follow-through and computed tomography, demonstrated dilated small bowel with possible strictures. Colonoscopy and upper endoscopy were unrevealing. Attempted capsule endoscopy resulted in capsule retention. Subsequent laparoscopy led to the identification of severe, active Crohn disease with strictures, ulcers, crypt abscesses, pyloric metaplasia, and transmural inflammation. Extensive flat and polypoid high- and low-grade dysplasia were present, as well as an area of well-differentiated adenocarcinoma invading into the muscularis propria. We discuss the epidemiology, pathogenesis, and diagnosis of small bowel malignancy. PMID:19917475

    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.

    International Nuclear Information System (INIS)

    X-ray-induced adenocarcinomas in the small bowels of outbred Lewis Brown Norway and Holtzman rats contained significantly lower concentrations of adenosine 3',5'-cyclic monophosphate than did normal rat intestinal tissue. No significant differences were observed between the intracellular concentrations of the nucleotide in the normal rat small bowel and those occurring in normal-appearing intestinal tissue exposed to tumor induction conditions

    Full Text Available AIM: To study the therapeutic efficacy of a new transnasal ileus tube advanced endoscopically for adhesive small bowel obstruction. METHODS: A total of 186 patients with adhesive small bowel obstruction treated from September 2007 to February 2011 were enrolled into this prospective randomized controlled study. The endoscopically advanced new ileus tube was used for gastrointestinal decompression in 96 patients and ordinary nasogastric tube (NGT was used in 90 patients. The therapeutic efficacy was compared between the two groups. RESULTS: Compared with the NGT group, the ileus tube group experienced significantly shorter time for relief of clinical symptoms and improvement in the findings of abdominal radiograph (4.1 ± 2.3 d vs 8.5 ± 5.0 d and laboratory tests (P < 0.01. The overall effectiveness rate was up to 89.6% in the ileus tube group and 46.7% in the NGT group (P < 0.01. And 10.4% of the patients in the ileus tube group and 53.3% of the NGT group underwent surgery. For recurrent adhesive bowel obstruction, ileus tube was also significantly more effective than NGT (95.8% vs 31.6%. In the ileus tube group, the drainage output on the first day and the length of hospital stay were significantly different depending on the treatment success or failure (P < 0.05. The abdominal radiographic improvement was correlated with whether or not the patient underwent surgery. CONCLUSION: Ileus tube can be used for adhesive small bowel obstruction. Endoscopic placement of the ileus tube is convenient and worthy to be promoted despite the potential risks.

    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.

    Background The management of nonstrangulating small bowel obstruction (SBO) may require surgery, but the need for and timing of surgical intervention isn’t always apparent. We sought to determine whether specific features on computed tomography (CT) can predict the necessity for operative management. Methods Two radiologists independently reviewed CT scans from all patients admitted to hospital with SBO between 2004 and 2006. We examined the association between radiographic features and operative management by univariate analysis using the ?2 or Fisher exact test. Significant factors with high concordance between radiologists were entered into a multivariable stepwise logistic regression model. Results There were 228 patients with SBO, 63 of whom met our inclusion criteria and had CT scans available for review. Three CT features were frequently associated with operative management and had good concordance between radiologists: complete bowel obstruction, small bowel dilation greater than 4 cm and transition point. Transition point was the only significant factor predictive of operative management for SBO on multivariable logistic regression analysis (OR 19, 95% confidence interval 1.8–201, p = 0.014). Conclusion In patients with nonstrangulating SBO, the presence of a transition point on CT scan should alert the surgeon to the increased likelihood that operative management may be required.

  11. 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.

  12. Misoprostol in the intestinal lumen protects against radiation injury of the mucosa of the small bowel

    International Nuclear Information System (INIS)

    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

  13. 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

    1976-03-01

    Prenatal occlusion of the superior mesenteric artery results in a distinct type of distal duodenal or proximal jejunal atresia in which the dorsal mesentery is absent and the distal small bowel assumes a spiral configuration around its vascular stalk, strongly resembling an apple peel. In some instances the condition is transmitted genetically as an autosomal recessive disorder. The mortality rate is much higher than in either simple duodenal or jejunal atresia because of deficient collateral circulation to the small intestine. The authors tell of 2 patients who died of necrotizing enterocolitis, a disease related to vascular insufficiency. PMID:1251017

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.

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

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

    Full Text Available 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 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 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.

    Although most patients with jejunoileal diverticulum are asymptomatic, a large, small-bowel diverticulum can be associated with midgut volvulus in an adult. We present a rare case of midgut volvulus that was associated with a large, small-bowel diverticulum in a 77-year-old woman presenting with chronic recurrent abdominal pain. The CT showed the characteristic whirl sign of twisted mesentery, the small bowel loops along the superior mesenteric artery and a large sac-like small-bowel diverticulum. A small bowel series also demonstrated a corkscrew appearance of proximal jejunum, a finding suggestive of midgut volvulus, and a large jejunal diverticulum. During the laparotomy, the small bowel was seen twisted counterclockwise 270 .deg.. The mesenteric root was very shortened. A 4 cm sized diverticulum was seen on the mesenteric border of jejunum, on the portion about 40 cm distal from the Treitz ligament.

    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.

  7. Ectopic intestinal glands after segmental small bowel irradiation in the cat

    International Nuclear Information System (INIS)

    Following segmental irradiation of the small bowel, 5 of 64 cats demonstrated ectopic intestinal glands in the submucosal tissue. In addition, one of these 5 cats had foci of abnormal glands in the muscularis mucosae. In 2 of the 5 animals, cellular polymorphism, nucleolar irregularity and loss of cellular polarity were present in irradiation-induced ectopic intestinal glands. The review of the literature indicates that intestinal irradiation may induce intestinal adenocarcinomas with metastatic growth. The possibility that ectopic intestinal glands are precancerous lesions in the irradiated cat is discussed. (Auth.)

    International Nuclear Information System (INIS)

    The authors studied the records of 46 patients who had been operated on between 1974 and 1990 in the Netherlands Cancer Institute because of complications due to late radiation damage of the small bowel. The following factors led to an increase in complication-risk: hypalbuminemia. more than one laparotomy prior to irradiation and a short interval (< 12 months) between irradiation and surgical intervention. The following factors related to a poorer survival: incomplete resection of the primary tumor and a short interval (< 12 months) between irradiation and surgical intervention. The type f surgical intervention did not have cumulative prognostic value in relation to complication-risk or survival. (author)

    Conclusion: Abdominal pain and distention of the abdomen are the most common symptoms and physical findings in patients presenting with acute mechanical small bowel obstruction (SBO. Worm (ascaridial obstruction is the most common cause of obstruction followed by postoperative adhesions. Although all patients were managed conservatively to start with, the operative rate in our series remained very high because it is very difficult to distinguish simple from strangulation obstruction on clinical, biochemical and/or radiological grounds with certainty.

    Full Text Available Hookworm infection is a relatively common cause of anemia in endemic areas. However, it is rarely encountered in Europe. In this report we describe the case of a 24-year old patient originating from an endemic area who was admitted due to severe anemia, with an Hct of 15.6% and eosinophilia (Eosinophils: 22.4%. While both esophagogastroduodenoscopy and colonoscopy were non-diagnostic, capsule endoscopy revealed a large number of hookworms infesting his small bowel and withdrawing blood. The patient was successfully treated with Albendazole. Capsule endoscopy was proven an important tool in diagnosing intestinal parasitosis.

    Nonimmune hydrops fetalis is observed with the frequency of 1:3000 cases diagnosed pre- and postnatally. In the following paper the authors analyzed the course of pregnancy complicated by fetal ascites and polyhydramnios with the appearance of colonic ileus and they presented the postnatal condition of the baby The preliminary diagnosis was confirmed after birth and the newborn was operated in the second day of his life. The congenital small bowel atresia was qualified as a III B type (Grossfeld qualification), which is called the "pagoda" syndrome [3]. The colonic atresia is located then around the superior mesenteric vessels, which leads to colonic necrosis (Figure 1). PMID:22379934

    Blunt traumatic diaphragmatic rupture (BTDR) is a life-threatening condition with an incidence from 0,8%–1,6% in blunt trauma, mostly located on the left side. The main prognostic factors are severe side injuries and the delay of diagnosis. We present a rare case of a 68-year-old female, with an isolated right diaphragm rupture. The diagnosis was done with a delay of 4 days by thoracic radiographs, which showed a herniation of small bowel into the right thoracic cavity. A reposition o...

  13. Characteristic imaging features of carcinoid tumors of the small bowel in MR enteroclysis

    International Nuclear Information System (INIS)

    To determine the value of MR enteroclysis (MRE) in the localization and characterization of primary carcinoid tumors of the small bowel and to describe typical imaging features. Twenty patients with suspicion of primary small bowel carcinoid tumors (pCT) were recruited to undergo MRE following nasojejunal intubation and small bowel filling with 2.5 l of 0.5% methylcellulose solution under MR fluoroscopic guidance. MRE was performed on a 1.5 T MR scanner including T2w SSFSE, SSFP and contrast enhanced T1w GRE sequences with fat saturation. Fifteen patients, who subsequently had surgery for resection of their pCT, were retrospectively included in the study. All MRE were analyzed as for the presence, location, number, size, multiplicity and morphologic appearance of the pCT by two board certified radiologists in consensus. The conspicuity of the tumors was rated for each sequence type separately, according to a 4-point rating scale. Signal intensity measurements were performed in tumor and muscle. The presence of desmoplastic reaction, vascular involvement and lymph node metastases was also analyzed. pCT were correctly identified and localized in 14/15 patients. Due to their hyperenhancement tumors was best detected on contrast-enhanced T1w fat saturated GRE sequences. SSFSE was clearly inferior with the tumors being either hyperintense or isointense to muscle. pCT appeared as nodular intraluminal masses in 40% of the cases, as focal wall thickening in 33.3% and in 20% wocal wall thickening in 33.3% and in 20% with both. Mean size was 25 (7-46 mm) with a tendency to smaller size for ileal tumors. MRE failed to depict superficial micronodular peritoneal spread in one patient. Desmoplastic reaction was observed in 73.3% of the cases with mesenteric masses exhibiting lower signal than the pCT due to fibrotic changes. MRE is a valuable method for the detection and localization of primary carcinoid tumors, provided that appropriate bowel distension is achieved. Various characteristic morphologic features could be identified which may contribute to characterize pCT and their loco-regional metastases. (orig.)

  14. 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

    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)

    The objective of this study is to investigate the effects of an acute necrotizing pancreatitis (ANP), without biliary obstruction, on the migrating motor complex (MMC), small bowel bacterial overgrowth (SBBO), bacterial translocation (BT) and infection of the pancreas simultaneously. Rats were divided into four groups: mild pancreatitis, control, ANP and sham operated control. Jejunal myoelectrodes were used to measure MMCs. Blood, peritoneal fluid, bile, and abdominal organs were harvested for microbial culturing 72 h after induction of pancreatitis. The splenic portion of the pancreas was taken for histology. During ANP the MMC cycle length was significantly increased from 14.1 +/- 0.2 to 22.4 +/- 1.9 min (P Enterobacteriacae (> 3 log 10 CFU g-1 in seven of 12 rats, P < 0.05). A positive correlation (r = 0.78, P < 0.01) existed between duodenal Gram-negative and anaerobic flora and the MMC cycle. Correlation between MMC cycle length and BT to the pancreas was positive as well (r = 0.70, P < 0.01). A positive correlation (r = 0.85, P < 0.01) was found between the severity of pancreatitis and duodenal bacterial overgrowth. During ANP without biliary obstruction, the jejunal MMC is disturbed and consequently SBBO occurs. The correlation between the severity of pancreatitis, the disturbance of the MMC and SBBO suggests an important pathophysiological role of the proximal small bowel in the infection of pancreatic necrosis.

  17. Profile of epidermal metabolic activity in autosomal dominant ichthyosis and small bowel disorders

    International Nuclear Information System (INIS)

    The in vitro incorporation of 14C acetate by the epidermis has been studied in patients with autosomal dominant ichthyosis and in patients with a dry, itchy, slightly scaly skin associated with a disorder of the small bowel. Analysis of 14C acetate containing lipid moieties by thin layer chromatography has indicated that there are both quantitative and qualitative differences in the uptake of 14C acetate between autosomal dominant ichthyosis and normal. In particular an increased incorporation into the triglyceride and phosphatidyl choline fractions was noted. No such differences were apparent in those patients with disorders of the small bowel. In addition the in vitro incorporation of radioactively labelled thymidine, proline and histidine has been studied in these patients. In both groups of patients the rate of incorporation of tritiated thymidine and histidine into epidermal macromolecules was found not to differ significantly from normal. On the other hand the rate of incorporation of tritiated proline was increased in both groups of patients. (author)

    A 67-year-old man from Jingzhou was admitted to the First Hospital Affiliated to Yangtze University in July 2013 with sudden onset of abdominal pain with dizziness for 12 h. The patient had sign of peritoneal irritation. Ultrasonography of the abdomen and pelvis showed hepatic fibrosis due to schistosomiasis. Computed tomography showed free gas in the peritoneal cavity. Plain abdominal radiography showed bilateral subdiaphragmatic accumulation of gas, perforation of the viscus, and radio-opacity in the left renal area. The patient underwent emergency exploratory laparotomy. At laparotomy, a moderate amount of muddy yellow pus was found in the intra-abdominal cavity. At the junction of the jejunum and ileum, about 250 cm from Treitz's ligament, there was an about 10-cm length of inflamed small bowel with perforation (3 mm in diameter) along the mesenteric border at the middle of the lesion. The patient underwent resection of the affected intestinal segment, along with end-to-end intestinal anastomosis. Histopathological examination revealed mucosal necrosis and hemorrhage with a large number of infiltrating eosinophils and neutrophils, and acute submucosal inflammation with a large number of infiltrating eosinophils and neutrophils associated with Schistosoma japonicum (S. japonicum) eggs. No intravascular adult parasite was found. Postoperatively, the patient was treated with praziquantel (30 mg/kg daily) for 4 d. The patient progressed well. To the best of our knowledge, this is the first case of small bowel perforation associated with eggs of S. japonicum. PMID:25759563

  19. 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

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

    International Nuclear Information System (INIS)

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

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

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

  4. Small bowel obstruction: the role of computed tomography in its diagnosis and management with reference to other imaging modalities

    International Nuclear Information System (INIS)

    Small bowel obstruction is a leading cause of acute surgical admissions for abdominal pain. There is an increasing tendency for initial conservative management rather than immediate operative intervention, as a proportion of cases will resolve spontaneously. This has resulted in a growing reliance on radiological investigations to reassure the surgeon that medical therapy can be safely instituted. The onus therefore rests with radiologists to guide their surgical colleagues by correctly interpreting the plain abdominal radiograph and suggesting appropriate further investigation if warranted. Recently, computed tomography (CT) has been proposed as the test of choice to define the level and cause of acute small bowel obstruction and to identify complications such as ischaemia and perforation which will prompt surgical intervention. This review will discuss the utility of early CT in the diagnosis of acute small bowel obstruction and outline its impact on patient management. (orig.)

    Massive small bowel resection (SBR) results in villus angiogenesis and intestinal adaptation. The exact mechanism that causes intestinal villus angiogenesis remains unknown. We hypothesize that hemodynamic changes within the remnant bowel after SBR will trigger intestinal angiogenesis. To validate this, we used photoacoustic microscopy (PAM) to image the microvascular system of the intestine in C57B6 mice and to measure blood flow and oxygen saturation (sO2) of a supplying artery and vein. Baseline measurements were made 6 cm proximal to the ileal-cecal junction (ICJ) prior to resection. A 50% proximal bowel resection was then performed, and measurements were again recorded at the same location immediately, 1, 3 and 7 days following resection. The results show that arterial and venous sO2 were similar prior to SBR. Immediately following SBR, the arterial and venous sO2 decreased by 14.3 +/- 2.7% and 32.7 +/- 6.6%, respectively, while the arterial and venous flow speed decreased by 62.9 +/- 17.3% and 60.0 +/- 20.1%, respectively. Such significant decreases in sO2 and blood flow indicate a hypoxic state after SBR. Within one week after SBR, both sO2 and blood flow speed had gradually recovered. By 7 days after SBR, arterial and venous sO2 had increased to 101.0 +/- 2.9% and 82.7 +/- 7.3% of the baseline values, respectively, while arterial and venous flow speed had increased to 106.0 +/- 21.4% and 150.0 +/- 29.6% of the baseline values, respectively. Such increases in sO2 and blood flow may result from angiogenesis following SBR.

    Chronic rejection is the major cause of late intestinal allograft dysfunction. The aim of this study was to analyze in detail the histopathological features of chronic rejection in the ACI-to-Lewis rat model of intestinal transplantation. Chronic rejection was achieved in orthotopic small-bowel allografts (ACI-Lewis) by limited immunosuppression with cyclosporin A (CyA). Isogeneic transplants (ACI-ACI) as well as native bowels (ACI) with and without immunosuppression served as controls. Bowels were removed together with the mesenteries 90 days postoperatively and analyzed using sections stained with hematoxylin and eosin as well as Masson's trichrome. The slides were coded, randomized and analyzed by grading of histological abnormalities. The most striking alterations of the allografts were noticed in the mesenteries exhibiting an extensive infiltration by mononuclear cells accompanied by a progressive diffuse fibrosis with shrinking of the mesenteries. These changes were most pronounced in the perivascular areas of the mesenteric arteriae and venae rectae. Three of five allografts showed vasculitis with myointimal proliferation of the arteriae rectae. Focally, there was spill-over of the inflammatory cells onto the intestinal muscularis propria. The mucosa of the allografts showed mild blunting, lymphocytic infiltration of the crypt epithelium and increased crypt cell apoptoses. The submucosa was unaffected, and there were no detectable abnormalities of the enteric ganglion cells. The present data support the view that chronic rejection of intestinal allografts is characterized by a diffuse sclerosing mesenteritis which may significantly contribute to late graft dysfunction. The present model may be useful to study the pathomechanisms of this inflammatory fibrosing process. PMID:12536314

    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.

  9. 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 paramepatients (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

  10. MR enteroclysis for MR diagnosis of inflammatory small bowel disease with contrast enhancement

    International Nuclear Information System (INIS)

    Purpose: To evaluate MRI for effectiveness in assessment of intra- und extramural changes in the small intestine. Methods: 40 patients with known or suspected small bowel disease underwent MR imaging immediately after conventional enteroclysis with barium and a mixture of methyl cellulose and gadolinium-DTPA. Results: In 6 of 24 patients with no pathological findings in conventional enteroclysis, intraabdominal pathology such as thickening of the intestinal wall and an abscess were identified. In the remaining patients, MRI showed good correlation with conventionally obtained data and provided important additional information regarding extraluminal involvement such as enlargement of mesenterial lymph nodes and fistulas as well as abscesses. Conclusions: MRI, carried out using this technique, provides important additional information regarding intra- and extraluminal changes with good image quality. (orig.)

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.

    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)

  15. Prospective study of treatment techniques to minimize the volume of pelvic small bowel with reduction of acute and late effects associated with pelvic irradiation

    International Nuclear Information System (INIS)

    The volume, distribution, and mobility of opacified pelvic small bowel (PSB) were determined by fluoroscopy and orthogonal radiographs in 150 consecutive patients undergoing pelvic irradiation. Various techniques including uteropexy, omental transposition, bladder distention, inclining the patient, and anterior abdominal wall compression in the supine and prone treatment position were studied for their effect on the volume and location of small bowel within the pelvis. Abdominal wall compression in the prone position combined with bladder distention was selected for further investigation because of its simplicity, reproducibility, patient comfort, and ability to displace the small bowel. Factors correlating with the volume of pelvic small bowel (PSB) included prior pelvic surgery, pelvic irradiation (XRT), and body mass index. After pelvic surgery, especially following abdominoperineal resection (APR), there was a greater volume of PSB which was also less mobile. The severity of acute gastrointestinal effects positively correlated with the volume of irradiated small bowel. Overall, 67% of patients experienced little or no diarrhea, 30% developed mild diarrhea, and no patient required treatment interruption. Late gastrointestinal effects correlated with the prior pelvic surgery and with the volume of small bowel receiving greater than 45 Gy. Small bowel obstruction was not observed in 75 patients who had no previous pelvic surgery. However, following pelvic surgery excluding APR, 2/50 patients and following APR, 3/25 patients developed small bowel obstruction

  16. 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 (wge 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

    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

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

    2012-01-31

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

    Full Text Available 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.

    Patients presenting with symptoms caused by gallstones are common on a surgical take. Understanding the different ways in which this common condition can present is important to enable the correct diagnosis and thus management plan. The immediate management of gallstones depends on the presenting features and can range from analgesia to surgical intervention. Obstructive cases require intervention, either by ERCP or surgery; the non-obstructive cases are usually left to settle before an elective operation at a later date. In surgery, the presence of a clinical sign where it 'should not be' can be a sign of another underlying pathology and this is the embodiment of surgery-to assimilate seemingly disparate pieces of information and act in a way to treat the cause. This case study highlights a rare presentation of one disease state, in vomiting of gallstones, that raised the diagnosis of another pathology, a small bowel obstruction. PMID:23608850

    Full Text Available Abstract Purpose As a foundation for a dose escalation trial, we sought to characterize duodenal and non-duodenal small bowel organ motion between fractions of pancreatic radiation therapy. Patients and methods Nine patients (4 women, 5 men undergoing radiation therapy were enrolled in this prospective study. The patients had up to four weekly CT scans performed during their course of radiation therapy. Pancreas, duodenum and non-duodenal small bowel were then contoured for each CT scan. On the initial scan, a four-field plan was generated to fully cover the pancreas. This plan was registered to each subsequent CT scan. Dose-volume histogram (DVH analyses were performed for the duodenum, non-duodenal small bowel, large bowel, and pancreas. Results With significant individual variation, the volume of duodenum receiving at least 80% of the prescribed dose was consistently greater than the remaining small bowel. In the patient with the largest inter-fraction variation, the fractional volume of non-duodenal small bowel irradiated to at least the 80% isodose line ranged from 1% to 20%. In the patient with the largest inter-fraction variation, the fractional volume of duodenum irradiated to at least the 80% isodose line ranged from 30% to 100%. Conclusion The volume of small bowel irradiated during four-field pancreatic radiation therapy changes substantially between fractions. This suggests dose escalation may be possible. However, dose limits to the duodenum should be stricter than for other segments of small bowel.

  3. Differentiation of obstructive from non-obstructive small bowel dilatation on CT

    International Nuclear Information System (INIS)

    Purpose: to find a useful decision procedure for the differentiation of obstructive from non-obstructive small bowel (SB) dilatation on the computed tomography (CT). Materials and methods: four criteria were divided into different degrees and evaluated. These include: (A): continuity (non-continuous, continuous); (B): transition zone (absent, gradual, abrupt); (C): prestenotic SB fluid (minimal, about one-fourth, one-half, and three-fourths, nearly complete); and (D): colonic contents (minimal, moderate, considerable). One hundred fifty-three examinations, 86 obstructive and 67 non-obstructive, were analyzed using ?2-square tests to determine the relationship of each criterion to the presence of small bowel obstruction (SBO), whether the proportions of various degrees of these criteria differed significantly among the obstructive and non-obstructive subgroups, and to classify the criteria with a tree-based model (calculated by the computer) for the development of a useful decision procedure. Results: in each of the four criteria, the trend of probability of obstruction was statistically significant (P=0.0000). The proportions of most, except two, of the various degrees of different criteria in the obstructive and non-obstructive subgroups differed significantly (P<0.01). The obstruction tends to have a continuou dilatation, an abrupt transition, more prestenotic SB fluids, and less colonic contents. The results of classification by a tree-based model were lassification by a tree-based model were 76 true-positive, ten false-negative, six false-positive, and 61 true-negative. The sensitivity was 88%; specificity was 91%; positive predictive value was 93%; negative predictive value was 86%; and the overall accuracy was 90%. Conclusion: by analyzing the above four criteria together, a useful tree-based model can be developed and utilized as a supplemental decision procedure for the differentiation of obstructive from non-obstructive SB dilatation. The accuracy can be further promoted if the factor of a recognized pathologic condition is taken into consideration

    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.

    2015-01-01

    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

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

    International Nuclear Information System (INIS)

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

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

    Directory of Open Access Journals (Sweden)

    Kurbel Sven

    2010-06-01

    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.

    Full Text Available There is no evident and precise data regarding the effect of cholecystokinin octapeptide (CCK-OP on the migrating myoelectric complex (MMC in sheep. Thus, in five rams seven bipolar platinum electrodes were implanted in the abomasal antrum and entire small intestine. The strain gauge force transducer was also attached near the duodenal electrode in three of these animals. During the experiments the myoelectric and motor activity was continuously recorded in fasted and non-fasted sheep. During the recordings two normal consecutive phases 3 of the MMC were recorded. Then, slow injections of CCK-OP of 0.02; 0.2 and 2.0 _g/kg of body weight were given intravenously during phase 1, 2a or 2b of the MMC, identified in the duodenum, until next two consecutive phases 3 MMC were recorded. The moderate dose of CCK-OP administered during phase 2a in non-fasted animals shortened the MMC cycles significantly while the highest dose of the hormone increased the cycle duration and inhibited phase 3 MMC in the duodenum. No such effect was observed in the jejunum. However, duration of phase 3 in this region was decreased mostly by the highest dose of CCK-OP. It can be concluded that CCK inhibits the MMC in ovine small bowel and its effect in the duodenum is most pronounced.

    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.

    Full Text Available Desde el año 2005, con previa capacitación de los integrantes del grupo en Pittsburgh (EU, y gracias al apoyo del hospital, decidimos crear la consulta de Rehabilitación Intestinal y Transplante de Intestino Delgado en el Hospital Pablo Tobón Uribe de Medellín (Colombia, a donde nos remiten, desde diversos lugares del país, pacientes con dificultades para su nutrición, a los cuales, con asesoría, los tenemos controlados con nutrición enteral y en algunos casos con nutrición parenteral ambulatoria con colaboración de sus entidades prestadoras de salud. Algunos de estos pacientes presentan falla intestinal o pérdida de accesos vasculares centrales para su nutrición parenteral y se les ofrece la posibilidad de transplante de intestino delgado. El grupo de Transplante de Intestino Delgado del Hospital Pablo Tobón Uribe está conformado por un equipo multidisciplinario de cirujanos de transplante, gastroenterólogos, anestesiólogos, nutricionistas, patólogos, trabajadora social, psicólogos, intensivistas y enfermeras. Desde febrero del año 2006 hemos realizado cuatro transplantes de intestino delgado aislado, a pacientes provenientes de distintas ciudades de Colombia, y hasta el momento hemos obtenido muy buenos resultados, logrando independencia nutricional, con una calidad de vida excelente que incluye retorno a su vida laboral. Todo esto ha sido posible gracias a la remisión de estos pacientes por médicos colegas de diferentes regiones del país, con el objeto de ofrecerles una opción de vida a estos individuos, que anteriormente fallecían en lamentables condiciones nutricionales y con infecciones sobreagregadas. Esperamos que en el futuro nos sigan enviando pacientes con este tipo de patologías para ofrecer con nuestro grupo multidisciplinario, esta alternativa de manejo.In 2005, with previous training of the medical team in Pittsburgh (USA and thanks to our hospital’s support, we decided to establish an Intestinal Rehabilitation and Small Bowel Transplant program at Pablo Tobón Uribe Hospital in Medellin (Colombia, where people from many places of the country come with nutritional deficiencies. These patients, with the support of nutritional group, receive home enteral and total parenteral nutrition (TPN with collaboration of their health insurance services. Some of these patients have intestinal failure or difficulties with central vascular access for their TPN, and in some cases our program offers the possibility of small bowel transplantation. The Small Bowel Transplant group of Pablo Tobón Uribe Hospital is integrated by multidisciplinary professionals (Transplant surgeons, gastroenterologist, anesthesiologist, pathologist, nutritionists, social work services, psychologist, intensive care physicians and nurses. Since February 2006 we have performed intestinal transplant in four adult patients, with excellent outcome, achieving nutritional independence and great quality of life. These results have been acquired thanks to early consultation and remission from our colleagues from different cities of Colombia. In the past, these patients frequently died secondary to severe malnutrition and infectious diseases. We hope in a near future to have the possibility of new cases in order to continue working with our main objective of offering an alternative to the management of these patients.

  12. Lymphocyte cytotoxicity in x-irradiation induced rat small bowel adenocarcinoma. IV. Activation of cellular immunity by x irradiation

    International Nuclear Information System (INIS)

    Exposure of only the ileum and jejunum of Holtzman male rats to 100 to 2000 R resulted in almost immediate and dose-dependent activation of anti-tumor cellular immune mechanisms, as measured in vitro by the cytotoxicity of the animals' peripheral blood lymphoid cells to allogeneic cultured cells from an x-irradiation induced Holtzman rat small bowel adenocarcinoma. These cytotoxic responses were somewhat specific; the lymphoid cells did not kill prostatic adenocarcinoma target cells and cytotoxicity could not be induced by x irradiation of some tissues other than the small bowel. Results suggest that exposure of an organ to ionizing radiation results in changes which sensitize the lymphoid cells in the animal to recognize and kill cancer cells of the particular tissue. Immunologic suppression by ionizing radiation presumably did not occur because only a small portion of the body was exposed

  13. 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 extende in patients who were treated with extended field radiotherapy (estimated small bowel volume 800 cm3) after intra-abdominal surgery.

    BackgroundSmall bowel angioectasia is reported as the most common cause of bleeding in patients with obscure gastrointestinal bleeding. Although the safety and efficacy of endoscopic treatment have been demonstrated, rebleeding rates are relatively high. To establish therapeutic and follow-up guidelines, we investigated the long-term outcomes and clinical predictors of rebleeding in patients with small bowel angioectasia.MethodsA total of 68 patients were retrospectively included in this study. All the patients had undergone CE examination, and subsequent control of bleeding, where needed, was accomplished by endoscopic argon plasma coagulation. Based on the follow-up data, the rebleeding rate was compared between patients who had/had not undergone endoscopic treatment. Multivariate analysis was performed using Cox proportional hazard regression model to identify the predictors of rebleeding. We defined the OGIB as controlled if there was no further overt bleeding within 6 months and the hemoglobin level had not fallen below 10 g/dl by the time of the final examination.ResultsThe overall rebleeding rate over a median follow-up duration of 30.5 months (interquartile range 16.5¿47.0) was 33.8% (23/68 cases). The cumulative risk of rebleeding tended to be lower in the patients who had undergone endoscopic treatment than in those who had not undergone endoscopic treatment, however, the difference did not reach statistical significance (P =0.14). In the majority of patients with rebleeding (18/23, 78.3%), the bleeding was controlled by the end of the follow-up period. Multiple regression analysis identified presence of multiple lesions (¿3) (OR 3.82; 95% CI 1.30¿11.3, P =0.02) as the only significant independent predictor of rebleeding.ConclusionIn most cases, bleeding can be controlled by repeated endoscopic treatment. Careful follow-up is needed for patients with multiple lesions, presence of which is considered as a significant risk factor for rebleeding. PMID:25430814

    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%)

    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)

  19. 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

    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.

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

    International Nuclear Information System (INIS)

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

  3. Prospective evaluation of magnetic resonance enterography for the detection of mesenteric small bowel tumours

    International Nuclear Information System (INIS)

    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.)

Two experienced investigators examined the videos and compared the total number of detected lesions to the number of lesions detected by each camera separately. Examination tolerability was assessed using a questionnaire.RESULTS: One patient was excluded. DCC cameras detected 68 positive findings (POS in 20 (50% cases. Fifty of them were detected by the “yellow” camera, 48 by the “green” and 28 by both cameras; 44% (n = 22 of the “yellow” camera’s POS were not detected by the “green” camera and 42% (n = 20 of the “green” camera’s POS were not detected by the “yellow” camera. In two cases, only one camera detected significant findings. All participants had 216 findings of unknown significance (FUS. The “yellow”, “green” and both cameras detected 171, 161, and 116 FUS, respectively; 32% (n = 55 of the “yellow” camera’s FUS were not detected by the “green” camera and 28% (n = 45 of the “green” camera’s FUS were not detected by the “yellow” camera. There were no complications related to the examination, and 97.6% of the patients would repeat the examination, if necessary.CONCLUSION: DCC SB examination is feasible and well tolerated. The two cameras complement each other to detect more SB lesions.

    We report on a small bowel transplant patient, donor/recipient seropositive (D+/R+) for cytomegalovirus (CMV), with a clinical course complicated by CMV disease. Anti-CMV prophylaxis was given for 100 days. Immunosuppression consisted of alemtuzumab, tacrolimus, mycophenolate mofetil and prednisolone. Five months posttransplant, CMV tissue invasive disease of the upper gastrointestinal tract was evident without the presence of viremia, tested by quantitative polymerase chain reaction (PCR). Complete viral load suppression was achieved with intravenous ganciclovir, followed by valganciclovir for secondary prophylaxis. Mycophenolate mofetil and prednisolone were discontinued. Shortly thereafter the patient presented with recurrent CMV and candida esophagitis. While on ganciclovir and caspofungin, the patient developed CMV tissue invasive disease of the ileal graft, with persistent absence of viremia. Foscarnet and CMV immunoglobulin were added. Viral load declined to undetectable levels; however, clinical improvement did not occur due to occurrence of graft rejection. Despite infliximab and high dose prednisolone, graft rejection was progressive, requiring surgical explantation of the graft. This case highlights the importance of additional diagnostic tools such as endoscopy including PCR analysis of tissue samples. Extension of primary antiviral prophylaxis interval up to 6 months and prolonged retreatment for recurrent CMV disease may be useful to avoid severe CMV-related complications. PMID:24703746

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.)

    PURPOSE. The aim of this study was to present the computed tomography (CT) findings of bezoars that cause obstruction in the small bowel and to emphasize that some CT findings can be considered specific to some bezoar types. MATERIALS AND METHODS. The records of 39 patients who underwent preoperative abdominal CT and subsequent operation with a diagnosis of intestinal obstruction due to bezoars were retrospectively analyzed. RESULTS. In total, 56 bezoars were surgically removed from 39 patients. Bezoars were most commonly located in the jejunum (n = 26/56, 46.4%). Sixteen (41.0%) patients had multiple bezoar locations in the gastrointestinal tract. Common CT findings in all patients were a mottled gas pattern and a focal ovoid or round intraluminal mass with regular margins and a heterogeneous internal structure. Furthermore, some CT findings were determined to be specific to bezoars caused by persimmons. CONCLUSIONS. Preoperative CT is valuable in patients admitted with signs of intestinal obstruction in geographic regions with a high bezoar prevalence. We believe that the correct diagnosis of bezoars and the identification of their number and location provide a great advantage for all physicians and surgeons. In addition, some types of bezoars have unique CT findings, and we believe that these findings may help to establish a diagnosis. PMID:23690741

    The purpose of this paper is to establish a small-bowel follow-through (SBFT) protocol in post-operative gastroschisis patients. In 15 years, 19 SBFT examinations have been performed to diagnose or exclude obstruction in 61 gastroschisis patients. The average examination required 6.7 overhead films (range 3-15) and lasted 34 h (1-190 h). The diagnosis of intestinal obstruction was supported on SBFT in only 1 of 19 patients who underwent this examination. In the other 18, the examination showed no obstruction (13 patients) or was nonconclusive (5 patients). The inherent dysmotility associated with gastroschisis can result in redundant overhead films being made during SFBT. We recommend that an SBFT examination in gastroschisis patients consist of (1) fluoro-evaluation of esophagus, stomach, and duodenum; (2a) if normal peristalsis is noted, then an overhead film at 30 min, or (2b), if altered peristalsis or little movement of contrast medium is noted on the 30-min overhead film, then an overhead film at 4 and 12 h. This is followed by overhead films every 24 h if required. This protocol can result in a decrease in patient radiation, department costs, and staff work load. PMID:7567233

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

  11. Measurement of small bowel transit time by 99Tcm-SC imaging: preliminary clinical study

    International Nuclear Information System (INIS)

    Objective: To develop a method of measuring small bowel transit time (SBTT) by 99Tcm-sulfur collide (SC) imaging and to compare with the method of added lactose in the test meal. Methods: 20 healthy volunteers and 26 patients with gastrointestinal disorders were studied. In fasting state, the subjects were asked to ingest the 99Tcm-SC labelled solid meal within 5 minutes, then the image acquisition was immediately started with SPECT. The images were acquired every 15 min during the first hour, at 30 min intervals during 2?4 hours and hourly thereafter until 80% radioactivity had entered the colon. One week later, the same procedure of imaging with 15 g lactulose added in the test meal was performed. The regions of interest (ROIs) were taken at stomach and colon, and the SBTT was calculated by deconvolution or by subtraction of the 50% time of gastric emptying from the 50% time of colon filling. Results: 1) The mean SBTT of 20 healthy volunteers was (4.2 +- 0.5) h, oral-caecum transit time (OCTT) was (4.3 +- 0.6) h; lactulose shortened the SBTT by (1.8 +- 0.6) h; 2) 26 patients showed different results of SBTT due to their different gastrointestinal disorders bases. Conclusions: 99Tcm-SC imaging was a noninvasive and useful method to measure SBTT. The added lactulose can shorten the examination time and help to identify the time of food to the ileocecal region

    Self-filling blind loops were created experimentally in jejunal segments of specific pathogen-free male Wistar rats, and the loop contents and mucosa were examined over an 8-week period for evaluation of the interaction between mucus and luminal bacteria. Corresponding jejunal segments from rats that did not undergo surgery were used as controls. Proliferation of anaerobic bacteria developed in the test animals by the first week after surgery. Despite anaerobic bacterial proliferation, no adherence by bacteria to the intestinal microvillus surface was observed by scanning or transmission electron microscopy. Rather, bacteria were present within the mucus layer overlying the intestinal mucosal surface. Immunoassay of goblet cell mucin demonstrated an increase in the proportion of mucin present in the intestinal lumen and a decrease in mucin levels in the jejunal mucosa. These results suggest that the interaction of bacteria with mucus is an important mechanism of protection of the mucosal surface in experimental small bowel bacterial overgrowth.

    AIM: To investigate the influence of remote ischemic preconditioning (RIPC) on anastomotic integrity. METHODS: Sixty male Wistar rats were randomized to six groups. The control group (n = 10) had an end-to-end ileal anastomosis without RIPC. The preconditioned groups (n = 34) varied in time of ischemia and time of reperfusion. One group received the amino acid L-arginine before constructing the anastomosis (n = 9). On postoperative day 4, the rats were re-laparotomized, and bursting pressure, hydroxyproline concentration, intra-abdominal adhesions, and a histological score concerning the mucosal ischemic injury were collected. The data are given as median (range). RESULTS: On postoperative day 4, median bursting pressure was 124 mmHg (60-146 mmHg) in the control group. The experimental groups did not show a statistically significant difference (P > 0.05). Regarding the hydroxyproline concentration, we did not find any significant variation in the experimental groups. We detected significantly less mucosal injury in the RIPC groups. Furthermore, we assessed more extensive intra-abdominal adhesions in the preconditioned groups than in the control group. CONCLUSION: RIPC directly before performing small bowel anastomosis does not affect anastomotic stability in the early period, as seen in ischemic preconditioning. PMID:21455330

    Previously, we have demonstrated that genetically disrupting retinoblastoma protein (Rb) expression in enterocytes results in taller villi, mimicking resection-induced adaption responses. Rb deficiency also results in elevated insulin-like growth factor-2 (IGF-2) expression in villus enterocytes. We propose that postoperative disruption of Rb results in enhanced adaptation which is driven by IGF-2. Inducible, intestine-specific Rb-null mice (iRbIKO) and wild-type (WT) littermates underwent a 50% proximal small-bowel resection (SBR) at 7-9 weeks of age. They were then given tamoxifen on postoperative days (PODs) 4-6 and harvested on POD 28. The experiment was then repeated on double knockouts of both IGF-2 and Rb (IGF-2 null/iRbIKO). iRbIKO mice demonstrated enhanced resection-induced adaptive villus growth after SBR and increased IGF-2 messenger RNA (mRNA) in ileal villus enterocytes compared to their WT littermates. In the IGF-2 null/iRbIKO double-knockout mice, there was no additional villus growth beyond what was expected of normal resection-induced adaptation. Adult mice in which Rb is inducibly deleted from the intestinal epithelium following SBR have augmented adaptive growth. IGF-2 expression is necessary for enhanced adaptation associated with acute intestinal Rb deficiency. PMID:25002022

  15. Peristalsis gap sign at cine magnetic resonance imaging for diagnosing strangulated small bowel obstruction. Feasibility study

    International Nuclear Information System (INIS)

    The aim of this study was to determine the feasibility of cine magnetic resonance imaging (MRI) for diagnosing strangulated small bowel obstruction (SBO). This study included 38 patients with clinically confirmed SBO who had undergone cine MRI. Cine MRI scans were evaluated regarding the presence of the 'peristalsis gap sign' (referring to an akinetic or severely hypokinetic closed loop), indicating strangulation. Computed tomography (CT) was performed in 34 of 38 patients with (n=25) or without (n=9) contrast enhancement. CT images were evaluated using a combination of criteria (presence of hyperattenuation, poor contrast enhancement, mesenteric edema, wall thickening, massive ascites) indicating strangulation. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of cine MRI and CT for the diagnosis of strangulation were calculated and compared using surgical findings and the clinical course as the reference standard. Sensitivity, specificity, PPV, and NPV of cine MRI were 100%, 92.9%, 83.3%, and 100%, respectively; and those of CT (of which 26.5% was performed without contrast enhancement) were 66.7%, 92.0%, 75.0%, and 88.5%, respectively. There was no significant difference in diagnostic accuracy between the two methods (P=0.375). Cine MRI is a feasible and promising technique for diagnosing strangulation. (author)

    2013-03-01

    Full Text Available We reported an abnormal case of strangulated incisional Richter’s hernia complicated by small bowel perforation and phlegmon of anterior abdominal wall. The observation is interesting due to the fact that now strangulated Richter’s hernia is rather rare but extremely dangerous concerning the following complications due to scant clinical presentation in strangulation. We represented a case of a female patient with two-day past history of strangulation. She had a classical clinical picture of strangulated Richter’s hernia (strangulation, necrosis, small bowel perforation, the anterior abdominal wall phlegmon, enterocutaneous fistula, the absence of peritonitis and peritoneal irritation signs, and the presence of paralytic ileus. The surgical management was performed followed by a patient’s complete recovery.

  18. Efficacy of an absorbable mesh in keeping the small bowel out of the human pelvis following surgery

    International Nuclear Information System (INIS)

    Patients with pelvic malignancies frequently require postoperative radiation therapy either as adjunctive or palliative treatment. Tumoricidal doses, however, are frequently associated with small-bowel damage. Animal experiments demonstrated tolerance to high-dose radiation therapy and protection from radiation enteritis by use of an absorbable polymer polyglycolic acid (PGA) that is used as an intestinal sling to elevate the small bowel away from the operated site. Sixty patients (42 with rectal carcinomas and 18 with gynecologic malignancies) underwent surgical treatment that included the intestinal sling procedure. Postoperative radiation was begun within three weeks following surgery and patients received a mean approximating 5500 rads in fractionated doses. A mean follow-up time of 28 months has not revealed a single case of radiation enteritis (by either contrast studies or physiologic studies) or PGA mesh-related complications. The authors believe that this surgical technique should be employed in patients who may require postoperative radiation treatment for pelvic malignancy

    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.

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

  6. 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

    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.

  8. 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)

  9. Contribution of multi-detector row CT (MDCT) to decision making in the management of patients with small bowel obstruction or ileus

    International Nuclear Information System (INIS)

    We retrospectively evaluated the contribution of multi-detector row CT (MDCT) to patient management decisions in 62 patients with small bowel obstruction or ileus. The sensitivity and specificity of MDCT diagnosis of small bowel obstruction with strangulation or closed loop were 78.9% (15/19) and 93.0% (40/43), respectively. In 19 patients with small bowel obstruction with strangulation or closed loop, the median interval between CT examination and the commencement of surgery was significantly longer in misdiagnosed patients than in those correctly diagnosed (43.3 vs. 4.5 hours, p<0.05). Only two patients displayed severe physical signs that required urgent surgical treatment. Our results suggest that MDCT plays a key role in the management of patients with small bowel obstruction.

    Introduction: The main role of the radiologist in the management of patients with suspicion of small bowel obstruction is to help triage patients into those that need immediate surgical intervention from those that require medical therapy or delayed surgery. Ultrasound examination is usually considered not helpful in bowel obstruction because of air in the intestinal lumen that interferes the evaluation of the intestinal loops, however recently some Authors attested the increasing important role of sonography in the acute abdominal disease. Aim of our report is to demonstrate the value of free fluid detected by US in differentiating between low and high-grade small bowel obstruction. Materials and methods: The study is based on 742 consecutive patients who presented symptoms of the acute abdomen; all patients had undergone initial serial abdominal plain film and US examinations prior to any medical intervention. We reviewed the imaging findings of 150 cases in whom small bowel obstruction was clinically suspected and confirmed at surgery. We consider the following radiographic and US findings: dilatation of small bowel loops; bowel wall thickness; presence of air-fluid levels; thickness of valvulae conniventes; evidence of peristalsis; presence and echogenicity of extraluminal fluid. We looked at the value of extraluminal peritoneal fluid at US examination in differentiating low and high-grade small bowel obstruction based on the surgical outcome. Results: In 46 patients altered peristaltic activity, thin bowel walls, fluid filled loops with hyperechoic spots in the bowel segment proximal to obstruction were noted at US, whereas radiographic features were: moderate dilatation of small bowel loops, with thin bowel wall and evidence of numerous and subtle valvulae conniventes; presence of air-fluid levels was also noted. In 70 other patients, US examination revealed all the findings described in the precedent cases and also the presence of free extraluminal fluid; abdominal plain film showed an increased dilatation of small bowel loops with moderate thickened wall and air-fluid levels. In 34 other patients US examination revealed the presence of thick-walled loops, hypoperistalsis and a larger amount of free extraluminal fluid. Radiographic findings in these patients were: horizontal featured and markedly dilated small bowel loops presenting parietal thickness, presence of intraluminal fluid stasis and evidence of thickened, sparse and incomplete valvulae conniventes. At surgery etiology of small bowel obstructions was various, but most of cases related to adhesions (70 cases). The presence of extraluminal fluid were confirmed at surgery in 104 patients. Conclusions: Our experience using sonography in suspicion of SBO (small bowel obstruction) suggests the usefulness of this imaging modality to differentiate a functional or obstructive ileus, demonstrating the evidence of intestinal peristalsis. Furthermore, the presence of a large amount of fluid between dilated small bowel loops suggests worsening mechanical small bowel obstruction, that requires not a medical therapy but immediate surgery.

    Sampling schemes developed for use with a geometric model of rat small bowel are tested against a design-based scheme (vertical sectioning with cycloid test lines) which offers unbiased estimates of surface amplifications due to villi. The model-based methods comprise transverse and longitudinal sectioning coupled with putative correction factors. Comparisons are based on proximal, middle and distal segments of six small bowels. Transverse and longitudinal sections through the same segments o...

    Small bowel obstruction is caused by postoperative adhesions in most patients. The traditional surgical treatment has been laparotomy with adhesiolysis and possible resection of the ischaemic intestine. The laparoscopic approach has proved feasible but not without risks. We analysed our experience in the management of acute small bowel obstruction and then reviewed the literature in an attempt to identify the real role of laparoscopy. From January 2003 to June 2008, 19 patients operated on for small bowel obstruction were identified. We evaluated our performance in terms of the aetiology of the obstruction, operative time, length of postoperative hospital stay, conversion rate, and major morbidity and mortality. Postoperative adhesions were responsible for the occlusion in 13 cases; a single band was identified in 47% of patients (9 cases). Neoplastic disease (3 cases), a gallstone ileus, Crohn's disease and an internal hernia were the remaining cases. Laparoscopic treatment was only possible in 7 patients with single adhesions (77%), and a conversion was carried out in the remaining 12 cases (63%), including "laparoscopy-assisted" cases (6 cases). The duration of the intervention (89 +/- 21 min vs 135 +/- 27.5 min) and postoperative hospitalisation (3.6 +/- 1 days vs 6.25 +/- 1.6 days) were in favour of the completely laparoscopic group as compared to the laparoscopy-assisted group. A case of postoperative peritonitis due to bowel perforation required a second intervention. With an appropriate selection of patients, confirming the high incidence of the single adhesions responsible for the occlusion and the resulting high success rate of laparoscopy, we believe that only an initial laparoscopic approach can help identify such favourable situations.

  15. Assessment of dynamic contrast enhancement of the small bowel in active Crohn's disease using 3D MR enterography

    International Nuclear Information System (INIS)

    Purpose: To retrospectively compare the dynamic contrast enhancement of the small bowel segments with and without active Crohn's disease at 3D MR enterography (MRE). Materials and methods: Thirteen patients (five men, eight women; mean age 41.2 years; range 29-56) were imaged on a 1.5-T MR scanner (Sonata, Siemens Medical) with standard MR sequences after having ingested 1000 ml of a 3% mannitol solution. Subsequently, high resolution 3D gradient-echo (volumetric interpolated breath-hold examination = VIBE) data sets were obtained pre-contrast and 20-40 s, 60-80 s, and 120-140 s after i.v. Gd-DOTA administration (0.2 mmol/kg). Signal enhancement was measured on single slices both in normal and histologically confirmed (12/13) inflamed small bowel wall segments as well as in the aorta, the psoas muscle, and the background to calculate signal-to-noise (SNR) and contrast-to-noise ratios (CNR). Results: Small bowel wall enhancement was significantly higher (p < 0.05) in inflamed compared to normal segments at 20-40 s (SNR inflamed: 58.7 ± 33.8 vs normal: 36.0 ± 19.8; p = 0.048; CNR inflamed: 34.8 ± 23.4 vs normal: 16.3 ± 11.2; p = 0.017) and at 60-80 s (SNR: 60.3 ± 25.1 vs 41.9 ± 20.0; p = 0.049; CNR: 34.9 ± 15.1 vs 19.3 ± 13.2; p = 0.01) after i.v. contrast administration, respectively. Even at 120-140 s CNR was still increased in inflamed segments (33.7 ± 16.0 vs 18.1 ± 13.2; p = 0.04), while differences in SNR did not attain statistical significance (63.0 ± atistical significance (63.0 ± 26.2 vs 45.3 ± 23.3; p = 0.15). Conclusion: In active Crohn's disease, histologically confirmed inflamed small bowel wall segments demonstrate a significantly increased early uptake of gadolinium on 3D VIBE sequences compared to normal small bowel segments.

    Full Text Available Abstract There are several surgical complications which can occur following simultaneous pancreas-kidney transplantation (SPKT. Although intestinal obstruction is known to be a common complication after any type of abdominal surgery, the occurrence of small bowel volvulus, which is one of the rare causes of intestinal obstruction, following SPKT has not been published before. A 24-year-old woman suffering from type I diabetes mellitus with complications of nephropathy resulting in end stage renal disease (ESRD, neuropathy and retinopathy underwent SPKT. On the postoperative month 5, she was brought to the emergency service due to abdominal distention with mild abdominal pain. After laboratory research and diagnostic radiological tests had been carried out, she underwent exploratory laparotomy to determine the pathology for acute abdominal symptoms. Intra-operative observation revealed the presence of an almost totally ischemic small bowel which had occurred due to clockwise rotation of the mesentery. Initially, simple derotation was performed to avoid intestinal resection because of her risky condition, particularly for short bowel syndrome, and subsequent intestinal response was favorable. Thus, surgical treatment was successfully employed to solve the problem without any resection procedure. The patient's postoperative follow-up was uneventful and she was discharged from hospital on postoperative day 7. According to our clinical viewpoint, this study emphasizes that if there is even just a suspicion of acute abdominal problem in a patient with SPKT, surgical intervention should be promptly performed to avoid any irreversible result and to achieve a positive outcome.

    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.

    The indications for small bowel barium examination, the radiologic findings, and the clinical outcome were compared retrospectively in 331 children, aged 0 to 15 years. Sixty examinations (18%) were pathologic, which is in accordance with adult materials. The most common indications for referral were inflammatory bowel disease (48%) and small bowel obstruction (25%). The examinations were positive in 19% and 17%, respectively. Indications for referring patients with non-specific symptoms led to a low frequency of pathologic findings. A therapeutic or diagnostic procedure was performed in 38 of the 60 pathologic radiologic examinations (63%). In 18 patients (30%) a pathologic finding caused no change in therapy. No consistent difference in sensitivity, specificity or predictive values of a positive or negative result was found concerning enteroclysis or elective follow-through examination. For screening purposes of the small bowel in children follow-through examinations give adequate radiologic information and should be used instead of enteroclysis. (orig.).

  19. Small bowel angioedema due to acquired C1 inhibitor deficiency: a case report and overview.

    Acquired angioedema is a rare disorder caused by an acquired deficiency of C1 inhibitor. It is characterized by nonpitting, nonpruritic subcutaneous or submucosal edema of the skin, or of the respiratory or gastrointestinal tract. When localized in the gastrointestinal tract, it can cause severe abdominal pain, mimicking an acute surgical abdomen, or chronic recurrent pain of moderate intensity. We report a case of a 48-year-old man presenting with recurrent episodes of hypotension and abdominal pain. Computed tomography of the abdomen showed edema of the small bowel. The first determinations of C1 inhibitor level and activity, measured in a symptom-free period, were normal. Repetition of the laboratory tests in the acute phase, however, showed a low C1 inhibitor level. Further diagnostic work-up indicated an acquired C1 inhibitor deficiency caused by a monoclonal gammopathy. He was treated with tranexamic acid as prophylaxis for his frequent attacks and to date, he has remained symptom free. Acquired C1 inhibitor deficiency is a rare cause of angioedema and is, among others, related to autoantibodies and abnormal B-cell proliferation, for example monoclonal gammopathy. The diagnosis of acquired C1 inhibitor deficiency is made on the basis of the medical history and on the level and activity of plasma C4, C1q, and C1 inhibitor. In case of high suspicion and a normal C1 inhibitor activity, it is recommended to repeat this test during an angioedema attack. Early diagnosis is important for the treatment of severe, potentially life-threatening attacks and to start prophylactic treatment in patients with frequent or severe angioedema attacks.

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

    Full Text Available Abstract Background Complicated diverticular disease of the colon imposes a serious risk to patient's life, challenge to surgeons and has cost implications for health authority. The aim of this study is to evaluate the management outcome of complicated colonic diverticular disease in a district hospital and to explore the current strategies of treatment. Methods This is a retrospective study of all patients who were admitted to the surgical ward between May 2002 and November 2006 with a diagnosis of complicated diverticular disease. A proforma of patients' details, admission date, ITU admission, management outcomes and the follow up were recorded from the patients case notes and analyzed. The mean follow-up was 34 months (range 6–60 months Results The mean age of patients was 72.7 years (range 39–87 years. Thirty-one men (28.18 % and Seventy-nine women (71.81% were included in this study. Male: female ratio was 1:2.5. Sixty-eight percent of patients had one or more co-morbidities. Forty-one patients (37.27% had two or more episodes of diverticulitis while 41.8% of them had no history of diverticular disease. Eighty-six percent of patients presented with acute abdominal pain while bleeding per rectum was the main presentation in 14%. Constipation and erratic bowel habit were the commonest chronic symptoms in patients with history of diverticular disease. Generalized tenderness was reported in 64.28% while 35.71% have left iliac fossa tenderness. Leukocytosis was reported in 58 patients (52.72%. The mean time from the admission until the start of operative intervention was 20.57 hours (range 4–96 hours. Perforation was confirmed in 59.52%. Mortality was 10.90%. Another 4 (3.63% died during follow up for other reasons. Conclusion Complicated diverticular disease carries significant morbidity and mortality. These influenced by patient-related factors. Because of high mortality and morbidities, we suggest the need to target a specific group of patients for prophylactic resection.

  3. MR imaging of the small bowel with increasing concentrations of an oral osmotic agent

    International Nuclear Information System (INIS)

    The aim of this study was to assess the quality of MR imaging and level of adverse effects with increasing concentrations of gastrografin. This is a prospective study with 24 healthy volunteers which were randomised into four groups receiving 50%, 25%, 10% and 0% gastrografin. The endpoint was bowel image quality based on distension, signal homogeneity and wall delineation evaluated by three independent radiologists, and the maximum bowel diameter at three different levels. The subjects also scored any adverse events on a 1-5 scale. The interradiologist agreement was relatively good, with kappa values varying between 0.81 and 0.41. Improved bowel distension and image quality were achieved with increasing concentrations. But significant dose-response effects were found between increasing osmolalities and the bowel diameters and also versus the score of adverse events. The most frequent adverse reactions were diarrhea, nausea and lack of palatability. There is a gradient relationship between increasing osmolality of gastrografin and improved image quality and the score of adverse effects. The optimum concentration of gastrografin is dependent of the tolerance of the adverse events. (orig.)

    Introduction Proteins are absorbed primarily as short peptides via PepT1. Hypothesis Intestinal adaptation for peptide absorption after massive mid-small intestinal resection occurs by increased expression of PepT1 in the remnant small intestine and colon. Methods Peptide uptake was measured in duodenum, jejunum, ileum, and colon using Glycyl-Sarcosine 1 wk (n=9) and 4 wk (n=11) after 70% mid-small bowel resection, and in corresponding segments from unoperated rats (n=12) and after transection and reanastomosis of jejunum and ileum (n=8). Expression of PepT1 (mRNA, protein) and villus height were measured. Results Intestinal transection/reanastomosis did not alter gene expression. Compared to non-operated controls, 70% mid-small bowel resection increased jejunal peptide uptake (p<0.05) associated with increased villus height (1.13 vs 1.77 and 1.50 mm resp, p<0.01). In ileum although villus height increased at 1 and 4 wk (1.03 vs 1.21 and 1.35 mm resp; p<0.01), peptide uptake was not altered. PepT1 mRNA and protein were decreased at 1 wk, and PepT1 protein continued low at 4 wk. Gene expression, peptide uptake, and histomorphology were unchanged in the colon. Conclusions Jejunal adaptation for peptide absorption occurs by hyperplasia. Distal Ileum and colon do not have a substantive role in adaptation for peptide absorption. PMID:21170601

    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.)

  8. Double and synchronous trichobezoars causing small-bowel obstruction and detected by multidetector computed tomography: report of two cases.

    2015-05-01

    A trichobezoar is a rare mass formed by the ingestion and accumulation of hair within the gastrointestinal tract, especially the stomach. Cases of an isolated gastric trichobezoar with extension into the duodenum or the jejunum have been reported; however, synchronous gastric and intestinal trichobezoars causing a small-bowel obstruction is very unusual. We report our experience of two such cases to demonstrate the efficiency of preoperative multidetector computed tomography in locating the double bezoars and assisting us in surgical decision making. Open surgery is inevitable for symptomatic bezoars, because the masses are too hard and large to break up with endoscopic devices. PMID:24823943

  9. Circulating blocking factors of lymphoid-cell cytotoxicity in x-ray-induced rat small-bowel adenocarcinoma

    International Nuclear Information System (INIS)

    Circulating blocking factors capable of abrogating cell-mediated immune responses measured by in vitro lymphoid-cell cytotoxicity were identified in the sera of Holtzman outbred rats 6 to 9 months after a single exposure of only the temporarily exteriorized, hypoxic ileum and jejunum to 1700 to 2000 R of X radiation. Such factors were found to exist in the serum of every animal exposed to the ionizing radiation regardless of whether a visibly identifiable small-bowel adenocarcinoma existed or subsequently would develop. Protection of cultured x-ray-induced rat small-bowel cancer cells from destruction by tumor-sensitized lymphoid cells as measured by the release of lactoperoxidase-catalyzed radioiodinated membrane proteins from the tumor target cells was conferred by the action of the blocking factors at both effector and target cell levels. The results of this study demonstrate that exposure of only the rat small intestine to ionizing radiation leads to elaboration of circulating factors identifiable several months postirradiation which will block cell-mediated immune responses directed against cancer cells developing in the exposed tissue

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

    International Nuclear Information System (INIS)

    Summary: Crohn's disease is more likely a systemic disease governed by a shift in the immune response, thus affecting the whole MALT system. Its treatment should be as conservative as possible and surgery is usually taking place after complications like indolent fistulations, stenoses, bleeding, or bowel perforation started. Standard radiological methods to check the extent of the disease are loaded either with certain radiation exposure (enteroclysis, CT) or lack standardization (ultrasound). The aim of this small study was to evaluate the worth of ultrasound-enteroclysis in detecting the extent and complications of the Crohn's disease in surgically treated patients. Material and methods: Since 1997, when we started with the ultrasound-enteroclysis, 246 surgical performances were involved into our study. Out of them, 181 had conventional abdominal intestinal ultrasound as well as conventional enteroclysis within 1 week. Remaining 65 cases were diagnosed by the ultrasound-enteroclysis. Intestinal ultrasound was performed on the Ultramark 3000 HDI device with autofocussable convex 5 MHz and linear 7.5 MHz probes or nowadays ATL 5000 HDI, 7-12 MHz linear probe. No contrast enhancement was used. Enteroclysis was done with the Micropaque suspension diluted 1:1 with HP-7000 300 ml with its application rate up to 75 ml/min followed by HP-7000 solution 2000 ml, application rate of 120 ml/min. The patients with ultrasound-enteroclysis were applied HP 7000 solution only (2000 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

  14. Transabdominal ultrasonography of the small bowel after oral administration of a non-absorbable anechoic solution: Comparison with barium enteroclysis

    International Nuclear Information System (INIS)

    AIM: The aim of this study was to determine if oral administration of a non-absorbable anechoic solution conveys any benefit during abdominal ultrasound (US), with special reference to its accuracy. MATERIALS AND METHODS: Fifty-three adult out-patients scheduled for small bowel barium enema (SBE) were included. The day before SBE all patients underwent abdominal US before and after oral administration of an isotonic non-absorbable electrolyte solution containing polyethylene glycol (PEG-ELS). Sensitivity and specificity were evaluated using SBE as a gold standard. RESULTS: After ingestion of PEG-ELS satisfactory distension of the intestinal lumen was obtained (11-25 mm) with sequential visualization of jejunoileal loops in 30.9 ± 17.3 min. In 15 out of 53 cases both US and SBE showed bowel changes characteristic of Crohn's disease. In three out of 53 cases both US and SBE showed neoplasms. In one out of 53 cases US was negative, SBE positive for local nodularity and ulcerations typical of Crohn's disease. In one out of 53 cases US was negative, SBE positive for macronodularity consistent with coeliac disease. In five out of 53 cases US was negative, while SBE was positive for mininodularity expressive of lymphoid hyperplasia. In 28 out of 53 cases both examinations were negative. CONCLUSION: PEG-ELS administration allows a thorough US investigation of the small bowel, with fair sensitivity (72%) and excellent specificity (100%). False negative findings are mainly due). False negative findings are mainly due to lymphoid hyperplasia, a feature of uncertain significance in adults. Cittadini G. et al.(2001)

  16. 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

  17. Ultrasonographic findings of the intestinal wall being changed by small bowel obstruction in rabbits: Correlation with histopathology

    International Nuclear Information System (INIS)

    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-obstron, 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.

    Full Text Available AIM: To evaluate the specific computed tomography (CT imaging criteria for differentiating tuberculosis involving the small bowel mesenteric lymph nodes from lymphomas.METHODS: We retrospectively reviewed the anatomic distribution, CT enhancement patterns of lymphoma in 18 patients with mesenteric tuberculosis and 22 with untreated non-Hodgkin’s lymphomas (NHL involving small bowel mesentery (SBM. Of the 18 patients with tuberculosis, 9 had purely mesenteric tuberculous lymphadenopathy (TL, and 9 had mesenteric TL accompanied with tuberculous mesenteritis (TLM.RESULTS: CT showed that tuberculosis and NHL mainly affected lymph nodes in the body and root of SBM. Homogeneously enhanced lymph nodes in the body and root of SBM were found more often in the NHL (P < 0.05. Homogeneously mixed peripheral enhanced lymph nodes in the body of SBM were found more often in mesenteric TL and TLM (P < 0.05. Peripheral enhanced lymph nodes in the root of SBM were found more often in mesenteric TL and TLM (P < 0.01. “Sandwich sign” in the root of SBM was observed more often in NHL (P < 0.05.CONCLUSION: Anatomic lymph node distribution, sandwich sign and specific enhancement patterns of lymphadenopathy in SBM on CT images can be used in differentiating between tuberculosis and untreated NHL involving SBM.

  20. 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

    A 72-year-old Caucasian man presenting with non-specific upper abdominal pain had asymmetric soft tissue thickening of the small bowel wall on computed tomography (CT), which was pathologically proven to be leiomyosarcoma (LMS). At the same time point patient had incidentally but retrospectively detected lesion in IVC on CT scan which was subsequently imaged with PET/CT and MRI and was histologically proven to be also LMS. We present clinical and imaging features along with pedigree of this unique case of synchronous primary LMS involving the small bowel and inferior vena cava in a patient with RB1 gene mutation and a significant family history of multiple malignancies. To our knowledge, the synchronous primary LMS at two different sites has not been described. Clinicians and radiologists should keep in mind the possibility of a synchronous primary LMS in patients with genetic predisposition before making the diagnosis of a metastatic lesion or other malignancy as localized primary tumors remain potentially curable, whereas metastatic sarcoma is most often incurable.

    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.

    From 1981 to 1991 inclusive, 188 operations were carried out for diverticular sigmoiditis. One hundred and thirty-nine patients were operated in emergency for acute complications (123) or fistulae (16), and another 49 had surgery scheduled outside acute crisis periods. Mortality and morbidity respectively are 16.5 and 31% in the first group, against 0 and 12% in the second one. Similarly, the stay in hospital varies from 13 days for scheduled surgery to 23 days for emergent surgery, the latter also requiring to account for risks and for the duration of a second operation that is far from exceptional (40%). Considering the severity of some evolutive complications, the authors advocate early radical surgery for symptomatic diverticular sigmoiditis, after the second crisis or as soon as the first one if it has been severe, and in young subjects and patients at risks.

    Full Text Available Abstract Background Capsule endoscopy with flexible spectral imaging color enhancement (CE-FICE has been reported to improve the visualization and detection of small-bowel lesions, however, its clinical usefulness is still not established. Therefore, we conducted a study to evaluate whether CE-FICE contributes to improve the detectability of small-bowel lesions by CE trainees. Methods Four gastroenterology trainees without prior CE experience were asked to read and interpret 12 CE videos. Each of the videos was read by conventional visualization method and under three different FICE settings. To evaluate whether the lesion recognition ability of the CE trainees could be improved by the FICE technology, the lesion detection rate under each of the three FICE settings was compared with that by conventional CE. CE trainees tend to miss small-bowel lesions in bile-pigment-positive condition, therefore we evaluated whether CE-FICE contributes to reducing the bile-pigment effect. The bile-pigment condition was determined by the color values around the small-bowel lesions according to the results of the receiver-operating-characteristic analysis. Moreover, we also evaluated whether poor bowel preparion might affect the accuracy of lesion recognition by CE-FICE. Results Of a total of 60 angioectasias, CE trainees identified 26 by conventional CE, 40 under FICE setting 1, 38 under FICE setting 2, and 31 under FICE setting 3. Of a total of 82 erosions/ulcerations, CE trainees identified 38 by conventional CE, 62 under FICE setting 1, 60 under FICE setting 2, and 20 under FICE setting 3. Compared with conventional CE, FICE settings 1 and 2 significantly improved the detectability of angioectasia (P?=?0.0017 and P?=?0.014, respectively and erosions/ulcerations (P?=?0.0012 and P?=?0.0094, respectively. Although the detectability of small-bowel lesions by conventional CE (P?=?0.020 and under FICE setting 2 (P?=?0.0023 was reduced by the presence of bile-pigments, that under FICE setting 1 was not affected (P?=?0.59. Our results also revealed that in poor bowel visibility conditions, CE-FICE yielded a high rate of false-positive findings. Conclusions CE-FICE may reduce the bile-pigment effect and improve the detectability of small-bowel lesions by CE trainees; the reliability of CE-FICE may be improved by good bowel preparation.

    A 6-year-old girl presented with presumed relapse of childhood immune thrombocytopenia. Investigations revealed deranged coagulation parameters, abnormal small bowel thickening, and splenomegaly. A clinically significant bleeding diathesis emerged which was refractory to most hemostatic interventions. Laparatomy revealed a composite diagnosis of splenic hemangiomatosis and small bowel lymphangiomatosis. Splenectomy resulted in complete resolution of the coagulopathy. The diagnosis and management of these conditions is inherently complex and without clear guidance. We discuss our perioperative management of the bleeding diathesis. There is a need for long-term follow-up of the underlying pathologies particularly as potentially useful therapeutic agents have emerged. PMID:24136025

    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 {sup 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 {sup 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.) [Deutsch] Zielsetzung: Bei der oralen Darstellung des Duenndarms mit der herkoemmlichen Kontrastmittelkombination kommt es haeufig zu einer mangelhaften Ausschwemmung des Bariumsulfats oder zu einer mangelhaften Distension der Darmschlingen, was zu einer schlechten Transparenz fuehrt. Wir verwendeten ein alternatives Distensionsmittel, das zu einer besseren Bildqualitaet und geschmacklichen Akzeptanz und dmait zu einer besseren Kooperation des Patienten fuehren sollte, ohne den Patienten vermehrt durch Strahlung Zeitaufwand zu belasten. Methode und Patienten: Wir untersuchten prospektiv 40 Patienten in zwei randomisierten Gruppen zu je 20 Patienten mit der herkoemmlichen Barium-Methylzellulose-Kombination bzw. der neuen Barium-Mucofalk {sup trademark} -Kombination (Flohsamenschalen). Erfasst und auf Gruppenunterschiedlichkeit untersucht wurden die Qualitaet des Semikontrastes, die Beurteilbarkeit des Schleimhautprofils, die adjuvante Medikation, die Durchleuchtungs- und Untersuchungszeit, das Flaechen-Dosis-Produkt und die geschmackliche Akzeptanz. Ergebnisse: Das neue Distensionsmittel wurde geschmacklich deutlich besser beurteilt: doppelt so haeufig mit ``gut`` und fuenfmal seltener mit ``schlecht``, allerdings aufgrund der geringen Patientenzahl nicht signifikant. Die uebrigen untersuchten Kriterien zeigten keinerlei Unterschiede in Signifikanz oder Tendenz. Schlussfolgerung: Ohne Einbussen an diagnostischer Qualitaet aber mit besserer geschmacklicher Akzeptanz kann das vorgestellte Distensionsmittel als Alternative bei Patienten eingesetzt werden, die die Sondenmethode ablehnen.

    Definite confirmation or exclusion closed loop obstruction (CLO) is one of the most difficult tasks the radiologist has to face in the clinical practice. Aim of this retrospective work was to study the value of spiral computed tomography (CT) in the diagnosis of closed loop obstruction complicated by intestinal ischemia. The state of the art CT signs of closed loop obstruction were taken into consideration. Serrated beaks with poor or no contrast enhancement of the bowel walls, ascites or engorgement of the mesenteric vasculature allowed the CT diagnosis of CLO complicated by ischaemia. U or C-sharped of dilated loops, radial distribution of the mesenteric vessels, beaks and whirls suggested CLO, but did not help differentiate CLO from strangulation. CLO is a dynamic entity which may regress or need laparotomy depending on the time and degree of rotation of the incarcerated loops. CT is a reliable imaging modality able to differentiate CLO from strangulation, which is rarely simple and obvious. Detection of ischemic changes in the bowel walls and/or attached mesentery on CT scans imply strangulation highlighting the need for laparotomy; if only signs of CLO are detected, the existence and/or development of strangulation cannot be predicted.

    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.)

  12. Calcifying Fibrous Tumor of the Small Bowel Mesentery in a 27-Year Old Male Patient - Case Report

    2014-12-01

    Full Text Available Calcifying fibrous tumor is a rare disease entity, usually concerning the soft tissues of the limbs, neck, trunk, or scrotum. Cases of the above-mentioned pathology have also been reported considering the pleural and peritoneal cavity, and small bowel mesentery.

    Calcifying fibrous tumor is a rare disease entity, usually concerning the soft tissues of the limbs, neck, trunk, or scrotum. Cases of the above-mentioned pathology have also been reported considering the pleural and peritoneal cavity, and small bowel mesentery. The essence of the disease, whose etiology and pathogenesis remains unclear, is the fibrous tissue infiltration and diffuse inflammation with focal calcifications. The study presented a case of a 27-year old male patient subjected to surgical intervention, due to an abdominal cavity tumor. The tumor was radically removed, and its character and definitive diagnosis were established postoperatively. After a seven-year follow-up period, recurrence was not observed. PMID:25527808

    Volvulus in pregnancy is rare and difficult to diagnose. Delayed diagnosis would result in high maternal and fetal mortality. Here we present an unusual case of small bowel volvulus in late pregnancy timely managed by emergency Cesarean section and derotation with excellent maternal and fetal outcomes. Volvulus should be considered in patients complaining ongoing abdominal pain, nausea, vomiting, constipation even diarrhea. Imaging is essential for early and precise diagnosis, including plain abdominal film, MRI and/or ultrasound. Once highly suspected or diagnosed of volvulus or ileus, emergency laparotomy should be performed immediately to avoid catastrophic outcomes, because the maternal and fetal prognosis is dependent on the interval from volvulus to operation apart from the degree of volvulus.

    Full Text Available Background: Capsule endoscopy (CE is a new diagnostic tool for the study of patients with suspected small bowel pathology. The aim of the study was to clarify the usefulness of CE in the group of patients with obscure (overt / occult gastrointestinal (GI bleeding. Patients and methods: Thirty patients (14 men, 16 women, mean age 50 years, range 9 -79 years were enrolled in the study. All of them undergone non-diagnostic esophagogastroduodenoscopy, colonoscopy and barium follow-through of the small bowel. All patients underwent capsule endoscopy. Fourteen patients had overt and sixteen occult bleeding. The single senior endoscopist interpreted CE findings in an unblended manner. Results: CE identified a source of bleeding in 14/30 patients (46,6 %. Lesions identified were: tumors in five pts, vascular lesions, Crohn's disease and Meckel's diverticulum in two pts and fresh bleeding, segmental celiac disease and colonic diverticulosis in one patient each. CE identified a source of bleeding in 9/14 (64,3% of patients with ongoing overt bleeding and in only 5/16 (31,3% of patients with occult bleeding. The positive suspicious findings were seen in 6/30 (20% of patients (2/14 with overt bleeding and 4/16 with occult bleeding. In 3/14 (21,4% with overt and 7/16 (43,7% with occult bleeding findings on CE were negative. All patients with negative findings on follow-up remained asymptomatic for one year. Capsule retention because of unsuspected stenosis occurred in a single patient and required surgery, which resolved the problem. Conclusion: CE is an effective diagnostic tool for patients with obscure GI bleeding. It is safe and painless technique which can diagnose the bleeding site beyond the reach of conventional endoscopy. The best candidates for the procedure are those with ongoing and overt bleeding.

    Full Text Available Diffuse intestinal pneumatosis appears as gaseous cysts in the intestinal wall in the submucosal layer or, more frequently, sub-serous layer. It affects more the jejunum than the ileum, can be diffuse and may extend into the colon. It's diagnosis is established during a small bowel transit examination, necropsy examination or during surgical exploration of the peritoneal cavity.

    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.

    Introduction Transabdominal preperitoneal endoscopic hernia repair (TAPP) is part of primary surgical health care. While both, the reported recurrence rate and procedure specific morbidity are consistently low, rare serious complications occur. Presentiation of case A 36-year-old male patient developed bowel obstruction three days after both-sided TAPP for inguinal hernia repair. A computer tomography scan of the abdomen revealed a small bowel volvulus in the right lower quadrant of the abdomen requiring urgent revisional surgery. Intraoperatively, the small bowel and its mesenterial vessels were found to be twisted around a 5 cm long V-Loc™ barbed absorbable suturing wire. After successful laparoscopic adhesiolysis, removal of the wire and detorquing of the bowel conglomerate, resection of small intestine was not necessary. The patient's further postoperative recovery was uneventful. Discussion Due to the barbed configuration of the V-Loc™ wire, a gapless continuous suturing of the peritoneum without laparoscopic knotting is easily and fast to accomplish. In this case the recommendation of the manufacturer to shorten the wire was not strictly followed and neither had the suture stump been extraperitonealized in order to avoid such rare complications. Conclusion Surgeons need to be aware of relevant “tricks and traps” of routinely performed procedures and have to know all tools and material they use very well. This case may therefore increase our attention when it comes to little things which actually do matter. PMID:25704567

    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.

    2014-01-01

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

    Full Text Available Abstract Introduction Superior mesenteric venous thrombosis as a result of acute cytomegalovirus infection is rare, with only a few cases reported in the literature. Case presentation We present the case of a 40-year-old Caucasian man who was admitted to our hospital with a 5-day history of fever. His serological test and pp65 antigen detection of cytomegalovirus were positive, suggesting acute infection. On the sixth day after his admission, the patient complained of acute, progressive abdominal pain. Abdominal computed tomography revealed acute superior mesenteric venous thrombosis. An emergency laparotomy showed diffuse edema and ischemic lesions of the small bowel and its associated mesentery with a 50-cm-long segmental infarction of the proximal jejunum. An extensive enterectomy of about 100 cm of jejunum that included the necrotic segment was performed, followed by an end-to-end anastomosis. Anti-coagulation therapy was administered pre-operatively in the form of small-fractionated heparin and continued postoperatively. The patient had an uneventful recovery and was discharged on the 11th postoperative day. Conclusion Acute cytomegalovirus infection can contribute to the occurrence of mesenteric venous thrombosis in immunocompetent patients. It is important for physicians and internists to be aware of the possible thrombotic complications of cytomegalovirus infection. A high level of clinical suspicion is essential to successfully treat a potentially lethal condition such as superior mesenteric venous thrombosis.

    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.

  3. Inflammatory bowel disease

    International Nuclear Information System (INIS)

    Radiology is of considerable value in all forms of inflammatory bowel disease to establish its presence and extent, and to differtiate lesions. The commenest inflammatory bowel diseases are Crohn's disease and ulcerative colitis. Crohn's disease may occur anywhere in the disgestive tract, but is most common in the terminal ileum. Since there is no practical endoscopic method of examining the small bowel, barium studies of the latter are most important. Modern radiological techniques, especially the doublecontrast barium enema, show excellent correlation between the macroscopic changes and the radiological features. Radiology alone does not provide the answers and the radiological features must be interpreted in conjunction with clinical investigation

    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 {sup 111}In-labelled test meal can also be used for the determination of colon transit in a single imaging study protocol. (orig.)

  5. Antibody-dependent cell-mediated cytotoxicity in x-irradiation-induced adenocarcinoma of the rat small bowel

    International Nuclear Information System (INIS)

    Antibody-dependent cell-mediated cytotoxicity (ADCC) was detected in the serum of Holtzman rats which had only their hypoxic ileum and jejunum exposed to 1700 to 2000 R of x rays, among which 10 to 25% would develop visible lesions in 4 to 6 months. All irradiated animals possessed serum which induced the in vitro injury of allogeneic cultured cells of an x-ray-induced rat small bowel adenocarcinoma by effector peripheral-blood lymphoid cells isolated from normal unexposed rats. The active serum component was apparently in IgG, on the basis of its solubility in ammonium sulfate solution, reactivity with anti-rat IgG and matrix-bound Protein A, molecular weight, and inactivity of F(ab')2 fragments. The in vivo significance of this ADCC is presently unclear since it existed in the serum of all rats exposed to the ionizing radiation regardless of whether they developed visible lesions. However, the results do suggest that if this immunological responsiveness plays a role in host tumor defense, then the deficiency in those rats developing the cancer may lie in their circulating effector cells

  6. Lymphocyte cytotoxicity in x-irradiation-induced rat small bowel adenocarcinoma. III. Blocking by 3 M KCl extract

    International Nuclear Information System (INIS)

    Hypertonic salt extracts (3 M KCl) of x-irradiation-induced Holtzman rat small bowel adenocarcinomas blocked the in vitro destruction of allogeneic cultured cells of this malignancy by sensitized lymphoid cells obtained from tumor-bearing animals. The protective effects were mediated by a blocking action at both the effector and the target cell level. The extracts were separated into 50 percent ammonium sulfate soluble and insoluble fractions with the soluble fraction being more effective in blocking the cytotoxic responses through interaction with the lymphoid cells whereas the insoluble one had a greater effect upon tumor target cells. Associated with both fractions was the oncofetal glycoprotein previously identified with the cellular membrane of this x-ray-induced malignancy. Immunoglobulins were identified with the insoluble fraction; some were able to bind the oncofetal protein, thus classifying it as a fetal antigen. The protective effects of the soluble fraction and this neoantigen were found to be citric and labile, whereas the effects due to the insoluble fraction were unchanged

  7. 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)

    Full Text Available The pathogenesis of nonsteroidal anti-inflammatory drug (NSAID) enteropathy is a complex process involving the uncoupling of mitochondrial oxidative phosphorylation and inhibition of cyclooxygenase (COX). Rofecoxib, a selective inhibitor of COX-2, has shown less gastric damage, but the same benefici [...] al effect is not clear in the case of the small bowel. Fifty-seven male Wistar rats (250-350 g) were divided into three groups (N = 19 each) to evaluate the effect of this NSAID on the rat intestine. The groups received 2.5 mg/kg rofecoxib, 7.5 mg/kg indomethacin or water with 5% DMSO (control) given as a single dose by gavage 24 h before the beginning of the experiment. 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

  9. 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)

  10. 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 tsup>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

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

    Strate, Lisa L; Erichsen, Rune

    2013-01-01

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

Abstract in english Aim: Colovesical fistula is a severe complication associated to neoplastic or inflammatory colon disease. Most common procedure is open surgery. We report a case of colovesical fistula secondary to diverticular disease treated with a laparoscopic approach. Methods: A 64-year-old man was seen with a [...] known colonic diverticular disease, type 2 diabetes mellitus and recurrent urinary tract infection. He complained of lower abdominal pain, dysuria, and pneumaturia. A CT scan revealed a sigmoid diverticular perforation into the bladder (colovesical fistula). A left hemicolectomy with partial cystectomy was performed by laparoscopy means. Results: There was no morbidity related to the surgical procedure, and the final pathology confirmed a colonic diverticular disease with bladder compromise. The patient is asymptomatic at 24 months of follow up. Conclusion: The laparoscopic approach is a feasible alternative for the treatment of colovesical fistula with low morbidity.

    Internal hernias involve protrusion of viscera through the peritoneum or mesentery into a compartment in the abdominal cavity. Hernias occurring through the meso-sigmoid are rare and the most common presentation of this entity is an acute small intestinal obstruction. Pre-operative diagnosis is often difficult and the diagnosis is usually made at surgery. Traditionally, open surgery is used to manage a meso-sigmoid hernia. We report a patient with meso-sigmoid hernia causing intestinal obstru...

  16. Small bowel CT fat density target sign in chronic radiation enteritis

    International Nuclear Information System (INIS)

    On CT, a thickened intestinal wall configured with a middle layer of low attenuation surrounded on each side by layers of higher attenuation has been termed the target sign. The presence of fat within the submucosal layer of the small intestine is a well-known manifestation of Crohn's disease, but has not been reported in other chronic intestinal diseases. We describe CT findings of fat density target sign in a patient with prior radiation. Copyright (2003) Blackwell Science Pty Ltd

    Experiments were carried out in healthy volunteers to explore the utility of a new (/sup 14/C)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 (/sup 14/C)lactulose was administered and the colonic entry time estimated from the time course of /sup 14/CO/sub 2/ excretion in breath compared with that of H/sub 2/ 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 /sup 14/CO/sub 2/ output was delayed when compared to H/sub 2/ output and was incomplete. The meal also contained xylose and (/sup 13/C)glycine, permitting the duodenal entry time of the meal to be estimated by the appearance of xylose in blood and /sup 13/CO/sub 2/ 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 /sup 14/CO/sub 2/-lactulose breath test. /sup 99/Tc radioactivity appeared in the cecum (as assessed using gamma scintigraphy) about 2 hr before /sup 14/CO/sub 2/ 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 (/sup 14/C)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.

    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.

  20. 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.

    Full Text Available Abstract Background Spontaneous gastrointestinal neoplasms in non-human primates are commonly seen in aged individuals. Due to genetic similarities between human and non-human primates, scientists have shown increasing interest in terms of comparative oncology studies. Case presentation The present study is related to a case of an intestinal leiomyoma in a black crested macaque (Macaca nigra, kept on captivity by Matecaña Zoo, Pereira City, Colombia. The animal had abdominal distension, anorexia, vomiting, diarrhea and behavioral changes. Clinical examination showed an increased volume in the upper right abdominal quadrant caused by a neoplastic mass. The patient died during the surgical procedure. Necropsy revealed several small nodules in the peritoneum with adhesion to different portions of the small and large intestines, liver, stomach and diaphragm. Tissue samples were collected, routinely processed and stained by H&E. Microscopic examination revealed a mesenchymal tumor limited to tunica muscularis, resembling normal smooth muscle cells. Neoplastic cells were positive for alpha-smooth muscle actin and vimentin, and negative for cytokeratin AE1/AE3 by immunohistochemistry. Those morphological and immunohistochemical findings allowed to diagnose the intestinal leiomyoma referred above. Conclusion Neoplastic diseases in primates have multifaceted causes. Their manifestations are understudied, leading to a greater difficulty in detection and measurement of the real impact provides by this disease.

    Fetal bowel obstruction has a prevalence of 1 in 3000 to 5000 live births. Ultrasonographic diagnosis is made by demonstrating distended loops of bowel. Echogenic bowel, defined as small bowel more echogenic than liver or bone, has been associated with congenital infections, cystic fibrosis, chromosomal abnormalities, and bowel obstruction. Fetal ascites, defined as fluid in the peritoneal cavity partly surrounding the liver and bladder, also has been associated with bowel obstruction. We present a case of jejunal atresia whose presenting appearance consists of echogenic bowel, transient ascites, and massive dilatation of intestinal loops. PMID:9805311

  3. 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%), 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

    We report the case of a 25-year-old male with Neurofibromatosis type I (NF-1), who presented at the time of admission with clinical findings of an acute abdomen caused by a mechanical obstruction. Computerized tomography showed a volvulus of the terminal ileum with mesenteric swirling as the cause of the patient's symptoms. Consecutive exploratory laparotomy confirmed the diagnosis and 70 cm of the small intestine was resected due to an affection of the mesentery by multiple neurofibromas. The gastrointestinal tract is affected in approximately 10% of patients with NF-1, however the mesentery is almost always spared. Here we describe the unique case of a patient with a volvulus caused by mesenteric manifestation of von Recklinghausen's disease, emphasizing the role of surgery in a team of multidisciplinary specialists to treat this multiorganic disease.

    It has been reported that the administration of anticholinergic drugs evokes inhibitory and excitatory responses, but the precise character of the latter has not yet been defined. This study was thus devoted to analyzing its occurrence following various doses of hexamethonium (Hx) and atropine (At) administration in the course of different phases of the small-intestinal migrating motor complex (MMC) in fasted and non-fasted sheep and to further characterize the excitatory responses in comparison with individual phases of the MMC. Two basic types of excitatory response were found. In the course of chronic experiments, various doses of Hx and At evoked rebound excitation (RE, i.e., irregular contractions or spike bursts evoked in response to the anticholinergic drug) alternating with phase 3-like activity (not the organized phase 3 of the MMC or its parts). The intensity of these changes varied and was related to the drug dose. Thus intense and non-intense RE activity were distinguished. In non-fasted sheep, these alterations were slightly less pronounced than in fasted animals. When the drug was given during phase 1 of the MMC, RE did not occur or was greatly reduced and its arrival was delayed. Hx triggered RE mostly in the duodenum, while the action of At was most effective in the jejunum. It is concluded that Hx and At initially hamper small-intestinal motility and just after that evoke a secondary stimulatory response, i.e., phase 3-like activity and RE of different intensity, duration, and repeatability in fasted and non-fasted sheep. These stimulatory effects may resemble unorganized phases of the MMC. PMID:20508285

    Purpose: To retrospectively compare the dynamic contrast enhancement of the small bowel segments with and without active Crohn's disease at 3D MR enterography (MRE). Materials and methods: Thirteen patients (five men, eight women; mean age 41.2 years; range 29-56) were imaged on a 1.5-T MR scanner (Sonata, Siemens Medical) with standard MR sequences after having ingested 1000 ml of a 3% mannitol solution. Subsequently, high resolution 3D gradient-echo (volumetric interpolated breath-hold examination = VIBE) data sets were obtained pre-contrast and 20-40 s, 60-80 s, and 120-140 s after i.v. Gd-DOTA administration (0.2 mmol/kg). Signal enhancement was measured on single slices both in normal and histologically confirmed (12/13) inflamed small bowel wall segments as well as in the aorta, the psoas muscle, and the background to calculate signal-to-noise (SNR) and contrast-to-noise ratios (CNR). Results: Small bowel wall enhancement was significantly higher (p < 0.05) in inflamed compared to normal segments at 20-40 s (SNR inflamed: 58.7 {+-} 33.8 vs normal: 36.0 {+-} 19.8; p = 0.048; CNR inflamed: 34.8 {+-} 23.4 vs normal: 16.3 {+-} 11.2; p = 0.017) and at 60-80 s (SNR: 60.3 {+-} 25.1 vs 41.9 {+-} 20.0; p = 0.049; CNR: 34.9 {+-} 15.1 vs 19.3 {+-} 13.2; p = 0.01) after i.v. contrast administration, respectively. Even at 120-140 s CNR was still increased in inflamed segments (33.7 {+-} 16.0 vs 18.1 {+-} 13.2; p = 0.04), while differences in SNR did not attain statistical significance (63.0 {+-} 26.2 vs 45.3 {+-} 23.3; p = 0.15). Conclusion: In active Crohn's disease, histologically confirmed inflamed small bowel wall segments demonstrate a significantly increased early uptake of gadolinium on 3D VIBE sequences compared to normal small bowel segments.

  7. A common cause of irritable bowel syndrome and diverticulitis: chronic distal colon distention from sedentary behavior and excessive dietary fiber.

    2013-07-01

    A multidisciplinary analysis restricted to validated reports was applied to the cause and management of irritable bowel syndrome and diverticular formation and subsequent diverticulitis. There is evidence that they are linked - both caused by attenuation of gravitational aid to distal intestinal motility, resulting in damaging chronic intestinal distention. Both irritable bowel syndrome and diverticular formation and subsequent diverticulitis have worsened in recent years owing to excessive dietary fiber intake. Potential solutions include augmenting weight-bearing time, moderating dietary fiber consumption, stimulating distal colon evacuation through chemical means and developing pharmaceuticals to block the reflexive distal colon distention associated with fiber consumption. Amplified intestinal distention commenced when all classes of Renaissance Europeans became the first group in human history to wear shoes, which led to a sedentary lifestyle that moderates gravitational aid to colon motility and evacuation.

  8. Dose-related effects of cerulein short infusions on proximal small bowel motility in sheep

    Scientific Electronic Library Online (English)

    K W, Romanski.

    Full Text Available The effect of cholecystokinin (CCK) upon the intestinal motility has not been entirely explored in ruminants. The aim of this study was to examine the precise effects of CCK amphibian analogue, cerulein, on small-intestinal myoelectric activity in rams in the course of chronic experiments. Five rams [...] underwent implantation of bipolar platinum electrodes to the duodenal bulb, the distal duodenum and jejunum. During continuous myoelectrical and motor recordings, 0.15 M NaCl or the various doses of cerulein were administered intravenously. Short infusions of the smallest dose of cerulein exerted a slight and mostly insignificant effect on the duodenal bulb and the duodenal myoelectric activity index (MAI) values. In the duodenal bulb, the effects of cerulein on myoelectric activity were dose-dependent and closely related to the phase of the MMC. In the duodenum, the higher doses of the hormone evoked short stimulatory response followed by longer inhibitory biphasic effects on MAI. These effects were inversely related to the duration of hormone injection. Infusions of hormones at the higher doses caused a less pronounced biphasic effect. It is concluded that cerulein exerts an inhibitory effect upon the myoelectric activity of the duodenal bulb and a strong stimulatory and inhibitory (biphasic) effect on duodenal motility in sheep.

  9. A case of small bowel injury induced by preoperative irradiation for rectal carcinoma

    International Nuclear Information System (INIS)

    A 54-year-old man underwent anterior resection with intraoperative radiation following preoperative irradiation for carcinoma of the rectum in August 1984, and subsequently was suffering from severe diarrhea and abdominal pain. One year and two months later he was admitted to our hospital with a sudden onset of lower abdominal pain, nausea and vomitting. The symptoms were so severe that emergency laparotomy was performed. There was no evidence of recurrent tumor, but the terminal ileum, from a point 30 cm. proximal to the cecum was found to be dark red, constricted and fixed to the urinary bladder. In addition, another two parts of the ileum from a point 50 cm. to that segment showed dark red. These damaged ileum were resected. Pathological examination revealed that there was thickness of the endothelium of arteriole and thromboses of the venule and mucosal damage (ie, ulceration, necroses). These vascular changes had resulted in radiation enteritis induced by preoperative radiotherapy. After the operation severe diarrhea continued until March 1986, when the granning diarrhea and pain became unbearable. At reoperation, another part of ileum was found to be dark red and constricted. There was a recurrent episode of radiation injury of small intestine. We report this case for the recognition of high-risk clinical factors and attention to careful selection or preparation of the patients with cancer for radiotherapy. (author)

    Small bowel carcinoid tumor (SBC) is a rare disease of unknown etiology but with an age-, sex-, and place-specific occurrence that may indicate an occupational origin. A European multicenter population-based case-control study was conducted from 1995 through 1997. Incident SBC cases between 35 and 69 years of age (n = 101) were identified, together with 3335 controls sampled from the catchment area of the cases. Histological review performed by a reference pathologist left 99 cases for study; 84 cases and 2070 population controls were interviewed. The industries most closely associated (a twofold or more odds ratio [OR]) with SBC, taking into account a 10-year time lag after exposure were, among women, employment in wholesale industry of food and beverages (OR, 8.2; 95% confidence interval [CI], 1.9 to 34.9]) and among men, manufacture of motor vehicle bodies (OR, 5.2; 95% CI, 1.2 to 22.4), footwear (OR, 3.9; 95% CI, 0.9 to 16.1), and metal structures (OR, 3.3; 95% CI, 1.0 to 10.4). The identified high-risk occupations with an OR above 2 were shoemakers, structural metal preparers, construction painters and other construction workers, bookkeepers, machine fitters, and welders (men). The OR for regular occupational use of organic solvents for at least half a year was 2.0 (95% CI, 1.0 to 4.2). Exposure to rust-preventive paint containing lead was suggested as another potential occupational exposure (OR, 9.1; 95% CI, 0.8 to 107). This explorative study suggests an association between certain occupational exposures and SBC, but some of these associations could be attributable to chance. All findings should be regarded as tentative. PMID:12085477

MÉTODO: Estudo retrospectivo incluindo 410 pacientes com lesão de intestino delgado operados entre janeiro de 1994 e dezembro d [...] e 2004. Os dados coletados incluíram: mecanismo de trauma, métodos diagnósticos, tempo transcorrido até a intervenção cirúrgica, grau das lesões, índices de trauma, conduta cirúrgica (sutura ou ressecção e anastomose), morbidade (especialmente fístula) e mortalidade. A comparação entre os grupos foi feita usando os testes de Fisher e Yates. RESULTADOS: O mecanismo de trauma foi penetrante em 321 pacientes (78,3%) e fechado em 89 (21,7%). Houve mais pacientes tratados cirurgicamente com intervalo maior que 6 horas após o trauma no grupo trauma contuso se comparados com trauma penetrante (p Abstract in english BACKGROUND: The purposes of this study were to evaluate the diagnosis and management of small bowel injury (SBI) and to determine significant factors affecting morbidity and mortality.
