    From February 1986 to March 1988 113 abdominal US exams were performed in emergency situation to evaluate the accuracy of this methodology: 13 were blunt traumas, 18 post-operative complications. A real-time scanner with a linear probe of 5 MHz was employed. The results were confirmed by surgical and/or clinical and instrumental evaluation. In 81% of the examinations, ultrasonography allowed a diagnosis to be made. Gallbladder and biliary pathologies were the most common findings. The results (sensibility 96%, specificity 88%, accuracy 95%) confirm the affidability of ultrasonography in abdominal emergencies, as shown in literature

    The anterior abdominal wall has received little attention in the ultrasonic evaluation. However recently the improved resolution of ultrasound scanning devices has made possible routine examination of the anterior abdominal wall. The authors evaluated ultrasonographic findings of anterior abdominal wall lesions in 27 cases for 1 year(from July '82 to Aug. '83), which were finally diagnosed pathologically and clinically. The results were as follows: 1. Well defined peritoneal line and layers of the anterior abdominal wall made it possible to localize the lesions accurately from adjacent structures. 2. Abscess and hematoma were lower in echogenecity than adjacent tissues, such as muscle layer or subcutaneous fat space and were well delineated from normal structures. 3. In hernia, easy differentiation was made due to oval shape, poor or decreased echo pattern and protrustion from skin layer. Conclusively, in the doubtful cases of palpable mass in the abdominal wall, postoperative complications of sequele, such as accurately but also the guide of treatment. Ultrasonography of anterior abdominal wall is useful to demonstrate the exact location, extent of the lesions and to decrease the frequency of useless laparatomy

    Abdominal radiography and ultrasonography are commonly used as part of the initial diagnostic plan for cats with nonspecific signs of abdominal disease. This retrospective study compared the clinical usefulness of abdominal radiography and ultrasonography in 105 feline patients with signs of abdominal disease. The final diagnosis was determined more commonly with ultrasonography (59%) compared to radiography (25.7%). Ultrasonography was also able to provide additional clinically relevant information in 76% of cases, and changed or refined the diagnosis in 47% of cases. Based on these findings, ultrasonography may be sufficient as an initial diagnostic test for the investigation of feline abdominal disease. PMID:26483582

    Out of 75 patients who were admitted to our hospital because of abdominal trauma and were undergone the procedures such as ultrasonography and/or CT scan within 24 hours of abdominal trauma due to suspected abdominal organ injury. We analyzed the results of 38 patients who were confirmed of diagnosis by operation, follow-up CT scan or ultrasonography. We analyzed the results of 38 patients who were confirmed of diagnosis by operation, follow-up CT scan or ultrasonography. 1. In the abdominal organ injury, solid organ injury consists of 8 cases of spleen laceration, 1 of splenic subcapsular hematoma, 7 of hepatic laceration, 7 of pancreas laceration, 3 of renal laceration, and 3 of subcapsular hematoma of kidney. 2. In addition, there were 7 bowel and/or mesenteric laceration, 2 diaphragmatic hernia, and 1 urethral rupture. 3. 2 cases of retroperitoneal hematoma and 1 case in which hemo peritoneum occurred without abdominal organ injury were confirmed by follow-up CT or ultrasonography. 4. In all of the 4 patients with multiple organ injury, pancreatic laceration was associated. 5. In abdominal trauma patients, ultrasonography or CT can be used to survey rapidly the entire abdomen for possible associated injury, and be of great help to clinicians in identifying the patients who need immediate surgery or in minimizing the incidence of unnecessary emergency abdominal exploration.

    An abdominal aortic aneurysm was detected in 77 patients among 16 488 abdominal ultrasonographies (US) performed in 1978-1983. In 62 cases the US finding was confirmed by operation, autopsy or other imaging method, and the US finding proved true in 60 cases. The length and diameter were accurately estimated and accompanying thrombosis reliably visualised. An error rate of 24% was observed in assessing the relation of the aneurysm to the renal arteries. US is recommended as the primary imaging mode in suspected abdominal aortic aneurysm. Screening of the abdominal aorta is recommended in elderly patients with abdominal pain and/or referred for abdominal US. (orig.) [de

    Chronic diarrhea is common in dogs and has many causes. Ultrasonographic descriptions of many gastrointestinal diseases have been published, but the diagnostic utility of ultrasonography in dogs with chronic diarrhea has not been investigated. Diagnostic utility of abdominal ultrasound will be highest in dogs with GI neoplasia and lowest in those with inflammatory disorders. 87 pet dogs with chronic diarrhea. Prospective study in which medical records were reviewed and contribution of abdominal ultrasound toward making diagnosis was scored. In 57/87 (66%) of dogs, the same diagnosis would have been reached without ultrasonography. In 13/87 (15%) of dogs, the ultrasound examination was vital or beneficial to making the diagnosis. Univariable analysis identified that increased diagnostic utility was associated with weight loss (P = .0086), palpation of an abdominal or rectal mass (P = .0031), diseases that commonly have mass lesions visible on ultrasound examination (P dogs in which an abdominal or rectal mass was palpated (odds ratio 30.5, 95% CI 5.5-169.6) (P dogs without a palpable mass. In 15/87 (17%) of dogs, additional benefits of ultrasonography to case management, independent of the contribution to the diagnosis of diarrhea, were identified. Overall, the diagnostic utility of abdominal ultrasonography was low in dogs with chronic diarrhea. Identification of factors associated with high diagnostic utility is an indication to perform abdominal ultrasonography in dogs with chronic diarrhea.

    In patients with diabetes mellitus, abdominal ultrasonography is the appropriate diagnostic technique to detect and to follow-up secondary and accompanying diseases of the liver, the kidneys, the pancreas, the gastrointestinal tract and of abdominal vessels. Moreover, pancreatic and hepatic diseases may be realized which are of etiological importance for diabetes mellitus. Based on a systematic survey of the published literature, this review in 3 parts will describe the value of abdominal ultrasonography in patients with diabetes mellitus. Part 1 deals with the diagnostic relevance and particular findings of ultrasonographic methods in hepatic manifestations and complications of diabetes mellitus. © Georg Thieme Verlag KG Stuttgart · New York.

    We report on our experience with routine abdominal ultrasonography in 120 children (aged 3-15 years) with recurrent abdominal pain, in order to determine the diagnostic value of this investigation. Eight children (7%) revealed sonographic abnormalities: gallbladder stone (n = 2), splenomegaly (n...... = 1) and urogenital abnormalities (n = 5). The recurrent abdominal pain could be explained by these findings in only two (may be three) cases. CONCLUSION: The diagnostic value of abdominal ultrasonography in unselected children with recurrent abdominal pain is low. However, the direct visualization...... of the abdominal structures as being normal may be helpful to the parents and the child in their understanding and acceptance of the benign nature of recurrent abdominal pain....

    Ultrasonography has been conducting a critical role in assessing abdominal disorders due to its noninvasive, real-time, low cost, and deep penetrating capabilities. However, for imaging obese patients with a thick fat layer, it is challenging to achieve appropriate image quality with a conventional beamforming (CON) method due to phase aberration caused by the difference between sound speeds (e.g., 1580 and 1450m/s for liver and fat, respectively). For this, various sound speed correction (SSC) methods that estimate the accumulated sound speed for a region-of interest (ROI) have been previously proposed. However, with the SSC methods, the improvement in image quality was limited only for a specific depth of ROI. In this paper, we present the adaptive sound speed correction (ASSC) method, which can enhance the image quality for whole depths by using estimated sound speeds from two different depths in the lower layer. Since these accumulated sound speeds contain the respective contributions of layers, an optimal sound speed for each depth can be estimated by solving contribution equations. To evaluate the proposed method, the phantom study was conducted with pre-beamformed radio-frequency (RF) data acquired with a SonixTouch research package (Ultrasonix Corp., Canada) with linear and convex probes from the gel pad-stacked tissue mimicking phantom (Parker Lab. Inc., USA and Model539, ATS, USA) whose sound speeds are 1610 and 1450m/s, respectively. From the study, compared to the CON and SSC methods, the ASSC method showed the improved spatial resolution and information entropy contrast (IEC) for convex and linear array transducers, respectively. These results indicate that the ASSC method can be applied for enhancing image quality when imaging obese patients in abdominal ultrasonography.

    In abdominal Ultrasonography, the fatty liver is diagnosed through hepatic parenchymal echo increased parenchymal density and unclear blood vessel boundary, and according to many studies, abdominal Ultrasonography has 60 ∼ 90% of sensitivity and 84 ∼ 95% of specificity in diagnosis of fatty liver, but the result of Ultrasonography is dependent on operators, so there can be difference among operators, and quantitative measurement of fatty infiltration is impossible. Among examinees who same day received abdominal Ultrasonography and chest computed tomography (CT), patients who were diagnosed with a fatty liver in the Ultrasonography were measured with liver Hounsfield Units (HU) of chest CT imaging to analyze the accuracy of the fatty liver diagnosis. Among 720 subject examinees, those who were diagnosed with a fatty liver through abdominal Ultrasonography by family physicians were 448, which is 62.2%. The result of Liver HU measurement in the chest CT imaging of those who were diagnosed with a fatty liver showed that 175 out of 720 had the measured value of less than 40 HU, which is 24.3%, and 173 were included to the 175 among 448 who were diagnosed through Ultrasonography, so 98.9% corresponded. This indicates that the operators' subjective ability has a great impact on diagnosis of lesion in Ultrasonography diagnosis of a fatty liver, and that in check up chest CT, under 40 HU in the measurement of Liver HU can be used for reference materials in diagnosis of a fatty liver

    Though the major target of the HIV-virus is the immune system, the frequency of abdominal disorders in HIV/AIDS patients has been reported to be second only to pulmonary disease. These abdominal manifestations may be on the increase as the use of antiretroviral therapy has increased life expectancy and improved quality of life. Ultrasonography is an easy to perform, non invasive, inexpensive and safe imaging technique that is invaluable in Africa where AIDS is most prevalent and where sophisticated diagnostic tools are not readily available. Purpose: To describe the findings and evaluate the clinical utility of abdominal ultrasonography in HIV/AIDS patients in Ibadan, Nigeria A Prospective evaluation of the abdominal ultrasonography of 391 HIV-positive patients as well as 391 age and sex-matched HIV-negative patients were carried out at the University College Hospital, Ibadan. Of the 391 cases studied, 260 (66.5%) were females; the mean age was 38.02 years, (range 15–66 years). The disease was most prevalent in the 4th decade with an incidence of 40.4%. Compared with the HIV-negative individuals, the HIV+ group of patients had a significantly higher proportion of splenomegaly (13.5% vs. 7.7%; p < 0.01), lymphadenopathy (2.0% vs. 1.3%; p < 0.70), and renal abnormalities (8.4% vs. 3.8%; p < 0.02). There were no differences in hepatic and pancreatic abnormalities between the HIV+ and HIV- groups. There were significantly fewer gallstones in the HIV+ group (1.4% vs. 5.1%; p < 0.01). AIDS is a multi-systemic disease and its demographic and clinical pattern remains the same globally. Ultrasonography is optimally suited for its clinical management especially in Africa. Its accuracy and sensitivity may be much improved with clinico-pathologic correlation which may not be readily available in developing countries; further studies may provide this much needed diagnostic algorithms

    A case of congenital abdominal dumbbell fashion neuroblastoma with invasion of the spinal canal detected by ultrasonography (US) is presented. A 3-week-old male neonate was admitted to the hospital with a palpable mass in the left lumbar region. Ultrasound examination was performed on the same day. It disclosed a pathologic mass filling the left side of the retroperitoneal space - displacing laterally and inferiorly the left kidney. The second part of the tumor was located above the Gerot's fascia in the muscles and infiltrated the tomography scanning confirmed the presence of solid masses in these locations. Urinary excretion of vanillin-mandelic acid (VMA) was within normal range, ferritin level was elevated (447 μg/ml). Bone scintigraphy showed metastases to the left clavicle. There were no changes in bone marrow. Diagnosis of an undifferentiated malignant neuroblastoma was established in histopathological examination. Spinal ultrasonography is highly recommended in neonates and infants with retroperitoneal tumors. (author)

    Results of preoperative ultrasonography and exploratory laparotomy were reviewed retrospectively in a series of 100 small animals to assess the agreement between ultrasonographic and surgical findings and to identify abdominal lesions likely to be missed by ultrasonography. Good agreement occurred between ultrasound reports and surgical reports in 64% of the animals, which supported the use of ultrasonography in potential surgical candidates. A major discrepancy was observed between the ultrasound report and surgical findings in 25% of the animals. Of the various types of pathology encountered in the study, gastrointestinal ulceration or perforation was the most likely lesion to be missed by ultrasonography.

    Purpose: To determine the usefulness of abdominal sonography in inherited diseases of carbohydrate metabolism. Materials and methods: Thirty patients (age range, 4 months to 27 years) with glycogen storage diseases, galactosemia, disorders of fructose metabolism were studied with sonography. Echogenicity of the liver, sonographic dimensions of liver, kidneys and spleen were evaluated. Plasma blood parameters (ALT, AST, total cholesterol, triglycerides) were determined. Results: Liver was enlarged in 21/22 patients (95.4%) with glycogen storage diseases, in both subjects with disorders of fructose metabolism, and in 2/6 patients (33.3%) with galactosemia. Hepatic echogenicity was increased in 20/22 patients (90.9%) with glycogen storage diseases, and in the subject with hereditary fructose intolerance. Patients with galactosemia did not show increased liver echogenicity. Both kidney were enlarged in 8/17 patients (47.0%) with glycogen storage disease type I. Subjects with increased hepatic echogenicity exhibited higher plasma concentrations of any blood parameter than the others with normal echogenicity (p [it

Patients and Methods: This prospective study of ultrasonographic examination in 146 paediatric patients presenting with acute onset abdominal pain at the emergency/paediatric outpatient department section of Jawaharlal Nehru Medical College & Hospital, Aligarh, between June 2006 and December 2007, using 3.75 MHz and 8 MHz transducers of the ADARA (Siemens machine. Results : Common causes of acute abdominal emergencies in pediatric patients as noted on ultrasonography included nonspecific pain (28%, abdominal abscess (21%, acute appendicitis (7% and intussusception (7%. Ultrasonography was diagnostic in 45.2% cases and supportive in 12.3% of the cases. As for as the final outcome, ultrasonography prevented surgery in almost 20% cases and laparotomy was avoided in 7% of the patients as ultrasound guided interventions in the form of abscess aspiration were carried out. Conclusion: Ultrasonography evaluation of children with acute abdominal pain, helps in making significant changes in the management plan of the patients, and also reveals various clinically unsuspected diseases.

    Ultrasonography and/or abdominal computed tomography revealed 9 patients with subphrenic abscesses derived from gastrointestinal surgery. Out of them 4 cases underwent conservative treatment is chosen with aggresive chemotherapy, but 5 were re-surgically treated including drainage of the intraperitonial abscess or repairing the leakage of the anastomosis. On the conservative treatment for the intraperitonial abscess, frequent monitoring with ultrasonography was very conventional for successful treatment. However, in the cases with severe leukocytosis, leakage of anastomosis or recurrent intraperitonial abscess, resurgical treatment will be required. Thus the monitoring with ultrasonography is quite usefull not only in the drainaging of the intraperitonial abscess, but also in the judgement of treatment whether conservetive or re-operative.

    Full Text Available Abdominal ultrasonography has been undervalued for years as technique used in examining the gastrointestinal tract. However, thanks to the technological advances that have been seen in ultrasonography probes and the use of high frequency equipment, we are able to obtain high quality images of the intestinal wall. Moreover, due to the increased sensitivity of the colour Doppler, we can detect the parietal vascularization. Finally, in recent years, intravenous ultrasonography contrast agents have been used that allow not only the inflammatory activity to be quantified but also the presence of complications with a diagnostic accuracy similar to computed tomography (CT and full magnetic resonance (full-RM, without the associated radiation risk and at a lower cost. This article reviews the utility of abdominal ultrasonography in inflammatory bowel disease, in particular Crohn's disease, both during initial diagnosis and follow-up of the disease; the article also reviews the ability of the technique to be used in the detection of complications (stenosis, fistulas and abscesses.

    Full Text Available Image fusion involving real-time ultrasound (US is a technique where previously recorded computed tomography (CT or magnetic resonance images (MRI are reformatted in a projection to fit the real-time US images after an initial co-registration. The co-registration aligns the images by means of common planes or points. We evaluated the accuracy of the alignment when varying parameters as patient position, respiratory phase and distance from the co-registration points/planes. We performed a total of 80 co-registrations and obtained the highest accuracy when the respiratory phase for the co-registration procedure was the same as when the CT or MRI was obtained. Furthermore, choosing co-registration points/planes close to the area of interest also improved the accuracy. With all settings optimized a mean error of 3.2 mm was obtained. We conclude that image fusion involving real-time US is an accurate method for abdominal examinations and that the accuracy is influenced by various adjustable factors that should be kept in mind.

The aims of this study were to assess the performance, feasibility, advantages and difficulties of the IOUS technique in dogs with suspected intra-abdominal tumors. The study included nine client-owed dogs that had suspected intra-abdominal tumors (spleen, liver or bowel based on transabdominal ultrasound examination and that were subsequently referred for exploratory laparotomy surgery. During surgery, IOUS was performed; results of preoperative transabdominal ultrasonography, inspection by the surgeon and IOUS were compared on a case-by-case basis. IOUS was helpful in determining lesion resection in all cases. Lesions detected solely by the use of IOUS were observed in seven out of nine cases. Analysis of these cases demonstrated that IOUS can be a tool to assist during oncology surgery on the liver, spleen or bowel. Dogs with hepatic tumors can have small non-palpable intraparenchymal nodules, which may be visible by IOUS.

    Abdominal obesity with visceral fat accumulation have been known to be intimately associated with the development of metabolic syndrome. Therefore, it is important to estimate the precise amount of visceral fat. Ultrasonography has been reported that it is a simple and noninvasive method for visceral fat evaluation. Purpose of this study is to evaluate the association of ultrasonographic visceral fat thickness, anthropometric indexes, and risk factor of metabolic syndrome, and to investigate the cut-off value of abdominal visceral fat thickness leading to increased risk of metabolic syndrome. The subject included 200 men and 200 women who visited D healthcare center in Daejeon from January to April 2008. The subcutaneous fat thickness and visceral fat thickness were measured by ultrasonograph. As anthropometric index, we measured body mass index, waist circumference and waist/height ratio. As for the risk factor of metabolic syndrome, we measured blood pressure, high density lipoprotein cholesterol, triglyceride and fasting serum glucose. VFT was significantly correlated with waist circumference, (r=0.683/M, r=0.604/F), waist to height ratio (r=0.633/M, r=0.593/F) and BMI (r=0.621/M, r=0.534/F) in both men and women. In addition it was significantly correlated with Systolic blood pressure (r=0.229/M, r=0.232/F), Diastolic blood pressure ((r=0.285/M, r=0.254/F), high density cholesterol (r=-0.254/M, r=-0.254/F), Triglyceride (r=0.475/M, r=0.411/F), and Fasting blood sugar (r=0.158/M, r=0.234/F) in both men and women. The cut-off value of visceral fat thickness leading to the increased risk of metabolic syndrome was 4.58 cm (sensitivity 89.2%, specificity 71.2%) in men and 3.50 cm (sensitivity 61.2% specificity 80.8%) in women respectively. The odds ratio of the risk of metabolic syndrome was dramatically increased with the abdominal visceral fat thickness level over 6 cm in men and 5 cm in women. The visceral fat thickness using ultrasonography was significantly

    Full Text Available Abstract: Annually hundreds of crab-eating foxes (Cerdocyon thous are referred to rehabilitation centers and zoos in Brazil. The ultrasonographic study of wildlife species is an important tool for a non-invasive and accurate anatomical description and provides important information for wildlife veterinary care. The aim of the present study was to determine the characteristics of the main abdominal organs as well as the vascular indexes of the abdominal aorta and renal arteries of crab-eating foxes (Cerdocyon thous using mode B ultrasonography and Doppler ultrasonography, respectively. Ultrasonographic features of the main abdominal organs were described and slight differences were noticed between ultrasound imaging of abdominal organs of crab-eating foxes and other species. The bladder presented wall thickness of 12±0.01mm, with three defined layers. Both, the right and left kidneys presented corticomedullary ratio of 1:1 and similarly to the adrenals and the liver, they were homogeneous and hypoechoic compared to the spleen. The spleen was homogeneous and hyperechoic compared to the kidneys. The stomach presented 3 to 5 peristaltic movements per minute, wall thickness of 39±0.05mm and lumen and mucosa with hyperechoic and hypoechoic features, respectively. Small and large intestines presented 2 to 3 peristaltic movements per minute, wall thickness of 34±0.03mm and three defined layers with hyperechogenic (submucosa and serosa and hypoechogenic (muscular features. Ovaries of the female crab-eating fox were hypoechoic compared to the spleen and with heterogeneous parenchyma due to the presence of 2x2mm ovarian follicles. Prostates of the six males were regular and with a well defined boundary, with a homogeneous and hyperechoic parenchyma compared to the spleen. Vascular indexes of the abdominal aorta (PSV: 25.60±0.32cm/s; EDV: 6.96±1.68cm/s; PI: 1.15±0.07 e RI: 0.73±0.07 and right (PSV: 23.08±3.34cm/s; EDV: 9.33±2.36cm/s; PI: 1.01±0

    To investigate the changes of activation of the abdominal muscles depending on exercise angles and whether the activation of rectus abdominis differs according to the location, during curl up and leg raise exercises, by measuring the thickness ratio of abdominal muscles using ultrasonography. We examined 30 normal adults without musculoskeletal problems. Muscle thickness was measured in the upper rectus abdominis (URA), lower rectus abdominis (LRA), obliquus externus (EO), obliquus internus (IO), and transversus abdominis (TrA), at pre-determined angles (30°, 60°, 90°) and additionally at the resting angle (0°). Muscle thickness ratio was calculated by dividing the resting (0°) thickness for each angle, and was used as reflection of muscle activity. The muscle thickness ratio was significantly different depending on the angles in URA and LRA. For curl up-URA p=0 (30°90°), p=0.44 (30°90°), p=0.44 (30°>90°), respectively, by one-way ANOVA test-and for leg raise-URA p=0 (30°abdominal muscles (EO, IO, and TrA). Also, there was no significant difference in the muscle thickness ratio of URA and LRA during both exercises. In the aspect of muscle activity, there was significant difference in the activation of RA muscle by selected angles, but not according to location during both exercises. According to this study, exercise angle is thought to be an important contributing factor for strengthening of RA muscle; however, both the exercises are thought to have no property of strengthening RA muscle selectively based on the location.

    The aim of this study was to estimate the results of the diagnostic imaging modalities, especially ultrasonography (US) in children during the oncological therapy with the acute abdominal symptoms. Acute abdominal symptoms in children with neoplasms causing a very difficult clinical and diagnostic problems and can occur in any stage of disease. The high-resolution ultrasound has a very important role in diagnosis in all patients with acute abdominal pain and with neoplasms. The authors consider that the US should be the first imaging method in the differential diagnosis of the abdominal changes in children with neutropenia and oncological disease. Proper diagnosis should be established only with clinical information. We analyzed 249 ultrasounds examinations of the abdominal cavity in 144 girls and 105 boys aged from 1 to 18 years (mean age 10, 3 years). The more important indication for the US exam in 133 cases was acute abdominal symptoms. We took exams during pre- and postoperative chemotherapy, radiotherapy and after the hematopoietic stem cell transplantation. All the patients were under routine hematological control. Based on the clinical symptoms and the laboratory tests we analysed two groups of children with oncological disease and acute abdomen: I group - 111 children with neutropenia, II group - 22 children without neutropenia. In the patients who underwent operation procedure the final diagnosis was established on histopathology. In the other cases diagnosis was based on clinical, laboratory and radiological exams, especially ultrasonography. We analyzed clinical picture of disease, the results of therapy and the US changes in examined patients using statistic parameters as: sensitivity, specificity and efficiency. In the group of 133 children with acute abdominal symptoms the most (92- 69,1%) patients suffer from ALL (acute lymphoblastic leukaemia) and 16(12%) - from AML (acute lymphoblastic leukaemia), Ewing sarcoma-3(2,2%), osteosarcoma - 3(2,2%), NHL

    Introduction: paracoccidioidomycosis (PCM) is a polymorphic systemic granulomatous inflammatory disease determined by Paracoccidioides brasiliensis, one of the 10 leading causes of morbidity and mortality among the parasitic diseases endemic in Brazil. Objective: To identify the following aspects of PCM by ultrasound (US) and computed tomography (CT): abdominal changes, intensity and characteristics of the observed images, frequency of changes depending on clinical presentation, differences from other nosological entities. Patients and methods: This was a retrospective, observational, cross-sectional study carried out with 35 patients with PCM treated at the Hospital das Clinicas (HC) at the Universidade Federal de Minas Gerais (UFMG). Patients with tuberculosis, bronchial asthma, generalized chronic obstructive pulmonary disease, or in contact with silica or mines, as well as those with granulomatous diseases at any point in their current or past clinical history and detected through serology, anatomopathology or microbiological exams were excluded. Collected data were transcribed into SPSS for Windows® for statistical analysis. The study was approved by the UFMG Ethics Committee (082/00). Results and conclusion: CT and U.S. showed involvement of abdominal organs in all forms of PCM, including lymphadenopathy (40%), hepatomegaly (37%), splenomegaly (37%) and adrenal involvement (17%). Gallbladder and retroperitoneal musculature involvement were also observed, along with ascites and pleural effusion. Lymph node calcification, adrenal involvement and ascites constituted evidence of high probability of PCM even though these findings are not enough to differentiate PCM from tuberculosis. Chronic and sequelae forms, abdominal involvement is more frequent than indicated by the clinical manifestations. (author)

    High proportion of TB in people living with HIV (PLHIV) is undiagnosed. Due to this active TB case finding is recommended for HIV clinics in high TB burden countries. Presently sputum examination and chest radiography are frontline tests recommended for HIV infected TB presumptives. Abdominal TB which occurs frequently in PLHIV may be missed even by existing programmatic intensified case finding protocols. This study evaluated the routine use of ultrasonography (USG) for active case finding of abdominal TB in HIV clinics. Retrospective analysis of eight years' data from an HIV Clinic in a TB hospital in India. Patients underwent chest x-ray, sputum examination, USG abdomen and routine blood tests at entry to HIV care. Case forms were scrutinized for diagnosis of TB, USG findings and CD4 cell counts. Abdominal TB was classified as probable or possible TB. Probable TB was based on presence of two major USG (abdomen) findings suggestive of active TB, or one major USG finding with at least two minor USG findings or at least two symptoms, or any USG finding with microbiologically confirmed active TB at another site. Possible TB was based on the presence of one major USG finding, or the presence of two minor USG findings with at least two symptoms. Bacteriological confirmation was not obtained. Eight hundred and eighty-nine people PLHIV underwent a baseline USG abdomen. One hundred and thirteen of 340 cases already diagnosed with TB and 87 of the 91 newly diagnosed with TB at time of HIV clinic registration had abdominal TB. Non-abdominal symptoms like weight loss, fever and cough were seen in 53% and 22% cases had no symptoms at all. Enlarged abdominal lymph nodes with central caseation, ascitis, splenic microabsesses, bowel thickening and hepatosplenomegaly were the USG findings in these cases. Abdominal TB is a frequent TB site in PLHIV presenting with non-abdominal symptoms. It can be easily detected on basis of features seen on a simple abdominal ultrasound

    Full Text Available BACK GROUND : Investigators have stressed the ability of CT and US to image abdominal masses and have touted them as first - line imaging modalities. MRI may be used to evaluate complex lesions not definitely characterized by US or CT. We want to evaluate the utility of U S and CT for evaluating abdominal masses in our rural India setup, wherein the study has to be appropriately utilized and tailored to the clinical need and also according to the socioeconomic situation. MATERIALS AND METHODS : This is a prospective observat ional study done in Department of Radiodiagnosis, PES Institute of medical sciences, Kuppam, between November 2011 to June 2013 in 30 patients with suspicious of abdominal masses and referred to the Department of Radio diagnosis and Imaging, for ult rasound and CT scan of abdomen. RESULTS : Ultrasound and CT has 73% and 100% sensitivity respectively for identifying the site of origin in abdominal and retroperitoneal masses when compared with surgical findings. Ultrasound is less sensitive for the detection of fat and characterization of retroperitoneal masses compared to CT. By combining the ultrasound and CT findings we can able to give the histopathological diagnosis in 83% c ases of abdominal mass lesions. CONCLUSION : We conclude that ultrasound and CT has additive role in the evaluation of abdominal masses and their management

    Many cats with gastrointestinal signs have coexisting abnormalities in the intestine, liver and pancreas. Investigations typically involve clinicopathological tests, diagnostic imaging and biopsy, either at coeliotomy or by non-invasive means. While exploratory coeliotomy enables all organs to be sampled simultaneously, it is invasive and might not be necessary. The aim of the current study was to assess the performance of preliminary clinical information in predicting the histopathological presence of abnormalities in alimentary tract organs in cats. The records of 38 cats with alimentary tract signs, which had ultimately undergone exploratory coeliotomy and surgical biopsy, were reviewed. The clinical signs, clinicopathological findings, diagnostic imaging findings and histopathology results were reviewed. On histopathological analysis, lesions were detected in 29/37 (78%) liver biopsies, in 29/35 (83%) gastrointestinal biopsies and in 17/37 (46%) pancreatic samples, the majority of which were inflammatory in nature. Clinical signs were generally poor markers of the presence of lesions in the alimentary tract. Further, while liver enzyme activity was relatively specific (88-100%) for detecting histopathological abnormalities in the liver, sensitivity was poor (11-50%). Pancreatic histopathological abnormalities were present in 1/3 of the cats with a positive pancreas-specific lipase result, and in 6/8 cats with a negative result. While relatively specific (57-100%) for both intestinal (57-100%) and hepatic (71-80%) histopathological abnormalities, abdominal ultrasonography lacked sensitivity for both organs (intestine 50-80%; liver 20-25%). In contrast, ultrasonography was relatively sensitive (50-80%), but not specific (17-22%) for detecting pancreatic lesions. Clinical signs, and clinicopathological and ultrasonographic abnormalities lack precision for hepatic and pancreatic histopathological lesions in cats with alimentary tract signs, and cannot reliably

    Full Text Available Autosomal dominant polycystic kidney disease produces symptoms mainly in adulthood. Renal cysts and/or elevated blood pressure can be the first signs of the disease in children. Because of the lack of a targeted therapy, early diagnosis and implementation of actions to slow its progression are the essence of treatment. Aim: The aim of the study was to assess the clinical course of autosomal dominant polycystic kidney disease in children. Material and methods: The study involved the assessment of 28 patients with autosomal dominant polycystic kidney disease diagnosed before the age of 18. The disease was diagnosed during a routine abdominal ultrasound scan in 24 patients and during a scan conducted due to abdominal pain reported by patients in 4 cases. Two patients had the disease diagnosed based on the Ravine criteria, whereas an ultrasound image and family history helped establish the diagnosis in 26 cases. The children enrolled had blood pressure measured, serum creatinine concentration determined and general urinalysis performed. Results: The median age at the diagnosis was 5 years. The family history was positive in 89.3% (25 of patients. Siblings had the disease in 46.43% (13 of cases. None of the children presented with abnormalities in urinalysis or creatinine levels. Two patients were diagnosed with arterial hypertension and in 1 child blood pressure was elevated above the 97th percentile. Urine albumin-to-creatinine ratio exceeding 30 mg/g was observed in 20.8% of children. Conclusions: Autosomal dominant polycystic kidney disease in children is asymptomatic. There are no irregularities either in urinalysis or renal function parameters. An abdominal ultrasound examination, which is inexpensive and non-invasive, is worth considering in all children of parents with autosomal dominant polycystic kidney disease in order to implement early nephroprotection.

    Purpose: To validate abdominal ultrasonography and helical computed tomography in detecting causes for sepsis in patients after abdominal surgery and to determine improved criteria for its use. Materials and methods: Eighty-five consecutive surgical patients primarily operated for non-infectious disease were included in this prospective study. Forty-one patients were admitted to the intensive care unit. All patients were suspected of an intra-abdominal sepsis after abdominal surgery. Both ultrasonography (US) and helical abdominal computed tomography (CT) were performed to investigate the origin of an intra-abdominal sepsis. The images of both US and CT were interpreted on a four-point scale by different radiologists or residents in radiology, the investigators were blinded of each other's test. Interpretations of US and CT were compared with a reference standard which was defined by the result of diagnostic aspiration of suspected fluid collections (re)laparotomy, clinical course or the opinion of an independent panel. Likelihood ratios and post-test probabilities were calculated and interobserver agreement was determined using κ statistics. Results: The overall prevalence of an abdominal infection was 0.49. The likelihood ratio (LR) of a positive test-result for US was 1.33 (95% CI: 0.8-2.5) and for CT scan 2.53 (95% CI: 1.4-5.0); corresponding post-test probabilities for US 0.57 (95% CI: 0.42-0.70) and for CT 0.71 (95% CI: 0.57-0.83). The LR of a negative test-result was, respectively, 0.60 (95% CI: 0.3-1.3) and 0.18 (95% CI: 0.06-0.5); corresponding post-test probabilities for US 0.37 (95% CI: 0.20-0.57) and for CT 0.15 (95% CI: 0.06-0.32) were calculated. Conclusion: Computed tomography can be used as the imaging modality of choice in patients suspected of intra-abdominal sepsis after abdominal surgery. Because of the low discriminatory power ultrasonography should not be performed as initial diagnostic test

The likelihood ratio (LR) of a positive test-result for US was 1.33 (95% CI: 0.8-2.5) and for CT scan 2.53 (95% CI: 1.4-5.0); corresponding post-test probabilities for US 0.57 (95% CI: 0.42-0.70) and for CT 0.71 (95% CI: 0.57-0.83). The LR of a negative test-result was, respectively, 0.60 (95% CI: 0.3-1.3) and 0.18 (95% CI: 0.06-0.5); corresponding post-test probabilities for US 0.37 (95% CI: 0.20-0.57) and for CT 0.15 (95% CI: 0.06-0.32) were calculated. Conclusion: Computed tomography can be used as the imaging modality of choice in patients suspected of intra-abdominal sepsis after abdominal surgery. Because of the low discriminatory power ultrasonography should not be performed as initial diagnostic test.

    Choledocholithiasis is one of the causes of jaundice and may require urgent treatment. Endoscopic retrograde cholangiopancreatography (ERCP) has been the primary management strategy for choledocholithiasis. However, small stones can be overlooked during ERCP. The aim of this study was to evaluate the accuracy of intraductal ultrasonography (IDUS) for detecting choledocholithiasis in icteric patients with highly suspected common bile duct (CBD) stones without definite stone diagnosis on ERCP. Ninety-five icteric (bilirubin ≥ 3 mg/dL) patients who underwent ERCP for highly suspected choledocholithiasis without definite filling defects on cholangiography were prospectively enrolled in the present study. We evaluated the bile duct using IDUS for the presence of stones or sludge. Reference standard for choledocholithiasis was endoscopic extraction of stone or sludge. Bile duct stones were detected with IDUS in 31 of 95 patients (32.6%). IDUS findings were confirmed by endoscopic stone extraction in all patients. The mean diameter of CBD stones detected by IDUS was 2.9 mm (range 1-7 mm). IDUS revealed biliary sludge in 24 patients (25.2%) which was confirmed by sludge extraction in 21 patients (87.5%). In dilated CBD, detection rate of bile duct stone/sludge based on IDUS was significantly higher than in non-dilated CBD (p = 0.004). IDUS is useful for the detection of occult CBD stone on ERCP in icteric patients with highly suspected CBD stones.

    The importance of the abdominal musculature in spine stability, has promoted the development of a variety of studies. Ultrasound imaging (UI) is a valuable tool which, when applied appropriately, has the potential to provide significant insight into abdominal muscle contraction. Limited studies have been taken place regarding the relationship between ultrasound measures of muscle thickening and electromyography (EMG) measures of activation. Inconsistent results, however, have been reported. Based on previous studies association between abdominal muscle activation and thickening may be affected by contraction level. The aims of this study were to measure the relationship between abdominal muscle thickness and abdominal muscles amplitude in different levels of abdominal muscles contraction. The research was carried on with a convenience sampling at the Physical Therapy Department of University of Social Welfare and Rehabilitation Sciences. Thirty healthy participants volunteered for this study. Muscle thickness right transversus abdominis (TrA) and obliqus internus (OI) muscles in abdominal hallowing maneuvers with and without pelvic floor muscle (PFM) contraction has been measured. Additionally, surface EMG of the right TrA/IO muscles was recorded. A hardware electrical part that acts as trigger system was used to record the activities of abdominal muscles in UI and EMG synchronously. Thickness change, normalized thickness and maximum amplitude abdominal muscles were used for statistical analysis. Correlations between the thickness change and amplitude measures were -0.03 -- 0.38 for TrA/IO. The Correlations between the normalized thickness and amplitude measures were -0.04--0.26 for TrA/IO. There is not clear relationship between increases in abdominal muscle activation and corresponding measures of thickening during abdominal muscle contraction. Changes in thickness of deep abdominal muscle cannot be used to indicate changes in the electrical activity in this

    Objective: We evaluated the diagnostic role of ultrasonography-guided core needle biopsy (CNB) according to ultrasonography features of thyroid nodules that had inconclusive ultrasonography-guided fine-needle aspiration (FNA) results. Methods: A total of 88 thyroid nodules in 88 patients who underwent ultrasonography-guided CNB because of previous inconclusive FNA results were evaluated. The patients were classified into three groups based on ultrasonography findings: Group A, which was suspicious for papillary thyroid carcinoma (PTC); Group B, which was suspicious for follicular (Hurthle cell) neoplasm; and Group C, which was suspicious for lymphoma. The final diagnoses of the thyroid nodules were determined by surgical confirmation or follow-up after ultrasonography-guided CNB. Results: Of the 88 nodules, the malignant rate was 49.1% in Group A, 12.0% in Group B and 90.0% in Group C. The rates of conclusive ultrasonography-guided CNB results after previous incomplete ultrasonography-guided FNA results were 96.2% in Group A, 64.0% in Group B and 90.0% in Group C (p=0.001). 12 cases with inconclusive ultrasonography-guided CNB results were finally diagnosed as 8 benign lesions, 3 PTCs and 1 lymphoma. The number of previous ultrasonography-guided FNA biopsies was not significantly different between the conclusive and the inconclusive result groups of ultrasonography-guided CNB (p=0.205). Conclusion: Ultrasonography-guided CNB has benefit for the diagnosis of thyroid nodules with inconclusive ultrasonography-guided FNA results. However, it is still not helpful for the differential diagnosis in 36% of nodules that are suspicious for follicular neoplasm seen on ultrasonography. Advances in knowledge: This study shows the diagnostic contribution of ultrasonography-guided CNB as an alternative to repeat ultrasonography-guided FNA or surgery. PMID:23564885

    Purpose: To determine the usefulness of abdominal sonography in inherited diseases of carbohydrate metabolism. Materials and methods: Thirty patients (age range, 4 months to 27 years) with glycogen storage diseases, galactosemia, disorders of fructose metabolism were studied with sonography. Echogenicity of the liver, sonographic dimensions of liver, kidneys and spleen were evaluated. Plasma blood parameters (ALT, AST, total cholesterol, triglycerides) were determined. Results: Liver was enlarged in 21/22 patients (95.4%) with glycogen storage diseases, in both subjects with disorders of fructose metabolism, and in 2/6 patients (33.3%) with galactosemia. Hepatic echogenicity was increased in 20/22 patients (90.9%) with glycogen storage diseases, and in the subject with hereditary fructose intolerance. Patients with galactosemia did not show increased liver echogenicity. Both kidney were enlarged in 8/17 patients (47.0%) with glycogen storage disease type I. Subjects with increased hepatic echogenicity exhibited higher plasma concentrations of any blood parameter than the others with normal echogenicity (p<0.05). Conclusions: Sonography can be useful in identification of inherited diseases of carbohydrate metabolism even if further examinations are necessary for an ultimate diagnosis.

    Despite the recent technological advances in imaging, abdominal ultrasonography continues to be the first diagnostic test indicated in patients with a suspicion of pancreatic disease, due to its safety, accessibility and low cost. It is an essential technique in the study of inflammatory processes, since it not only assesses changes in pancreatic parenchyma, but also gives an indication of the origin (bile or alcoholic). It is also essential in the detection and tracing of possible complications as well as being used as a guide in diagnostic and therapeutic punctures. It is also the first technique used in the study of pancreatic tumors, detecting them with a sensitivity of around 70% and a specificity of 90%.

None of the regression models developed for the abdominal muscles exhibited statistical significance. A significant and negative association (p=0.018; β=-0.0343 was observed only between UI and IO recruitment. Conclusion: These results suggest that age-related factors may have interfered with the findings of the study, thus emphasizing the need to perform ultrasound imaging-based studies to measure abdominal muscle recruitment in the elderly.

    Surgeons are increasingly using ultrasonography (US) in their clinical management of patients. However, US is a very user-dependent imaging modality and proper skills of the US operator are needed to ensure quality in patient care. This thesis explores the validity evidence for assessment of competence in abdominal and head & neck ultrasonography using the Objective Structured Assessment of Ultrasound Skills (OSAUS) scale. With the use of Messick's unitary framework of validity, five sources of validity evidence were explored: test content, response processes, inter-nal structure, relations to other variables, and consequences. Research paper I examined validity evidence for the use of the OSAUS scale to assess physicians' abdominal point-of-care US competence in an experimental setting using patient cases with and without pathological conditions. The RESULTS provided validity evidence of the internal structure of the OSAUS scale and a deci-sion study predicted that four cases and two raters or five cases and one rater could ensure sufficient reliability in future test setups. The relation to other variables was supported by a signifi-cant difference in scores between US experience levels, and by a strong correlation between the OSAUS score and diagnostic accuracy. Research paper II explored the transfer of learning from formal point-of-care US training to performance on patients in a randomized controlled study. The RESULTS supported validity evi-dence regarding OSAUS scores' relation to other variables by demonstrating a significant discrimination in the progress of training-a more refined validity evidence than the relation to difference experience levels. The RESULTS showed that physicians could transfer the skills learned on an ultrasonography course to improved US performance and diagnostic accuracy on patients. However, the RESULTS also indicated that following an initial course, additional training is needed for physicians to achieve competence in US

    Epiploic appendicitis is an uncommon inflammatory condition, which is presently better diagnosed by current imaging methods such as computed tomography and ultrasonography that allow a non-invasive and efficient diagnostic approach. The author studied 6 patients with epiploic appendicitis. The patients were submitted to computed tomography that showed paracolic oval lesions of 1 to 2 cm of diameter, fat attenuation and a thin peripheral hyperdense rim associated with adjacent fat stranding. Ultrasound examination performed in two patients showed hyperechoic ovoid noncompressible masses at the site of maximum abdominal tenderness. (author)

    Hepatic abscess is a rare complication of fasciolasis. The ultrasonographic appearances of these abscesses are not well known. The finding of nodular echodense images in the hepatic parenchyma may cause diagnostic confusion. We report three cases in which abdominal ultrasonography demonstrated hepatic abscesses complicating fascioliasis. Follow-up examination showed regression of these lesions after treatment.

    Authors analyzed the distribution of diseases and compared ultrasonographic conclusions with confirmed diagnoses of emergency abdominal ultrasonographies in acute abdominal conditions. We evaluated the role of emergency abdominal ultrasonography especially in the decision of emergency operation. In one hundred and forty five patients, emergent abdominal ultrasonography was performed within on admission. We compared the sonographic conclusion with postoperative pathology and analyzed the diagnoses of medically treated diseases. Twenty-eight patients underwent surgery and 117 patients were treated conservatively. Among the surgically treated patients, 19 patients (70.4%) were correctly diagnosed by preoperative ultrasonography.These included acute appendicitis (N = 8), acute cholecystitis (n = 7), ovarian cyst torsion (n = 2), and liver abscess (n = 1). Correct preoperative diagnosis was not made in 9 patients, including acute appendicitis (n = 4), peritonitis due to bowel perforation (n = 2), ectopic pregnancy (n = 1), colonic diverticulitis (n = 1) and pelvic inflammatory disease (n = 1). Clinical follow up was possible in 50 patients among the non-operative patient group, and the clinical diagnoses were chronic liver disease (n = 14), acute pyelonephritis (n = 10), and biliary stone (n = 10).

    Polycystic disease is defined as a heritable disorder with diffuse involvement of both kidneys. The term 'Polycystic disease' comprises at least two separate, genetically different disease-one with an onset typically in childhood (infantile polycystic disease) and the other with an onset typically in adulthood (adult polycystic disease). Adult polycystic kidney disease is the most common form of cystic kidney disease in humans. Ultrasonography is a very useful noninvasive diagnostic modality in the patient with clinically suspected renal diseases as well as screening test. 14 cases of ultrasonography in patient with polycystic kidney were reviewed. All cases show unilateral or bilateral enlarged kidneys. 7 cases reveal kidneys and liver replaced by multiple cysts of varing size. Screening ultrasonography for a familial tree is reported

    Full Text Available BACKGROUND Fine-Needle Aspiration Cytology (FNAC is a widely used method, which is accurate and safe in a readily palpable masses. But, in those inaccessible lesions and deeper organs are safely aspirated using fine needle radiological procedure like ultrasound or computed tomography guided. The aim of the study is to assess the utility of FNAC in the diagnosis of intra-abdominal lesions and different pattern of lesions in particular to the sites. MATERIALS AND METHODS This retrospective study was done in the Department of Pathology, Regional Institute of Medical Sciences (RIMS, Imphal, between June 2010 and June 2016. The study included 128 intra-abdominal masses. Giemsa and Papanicolaou’s stains were used. The cytological diagnosis was correlated with clinical and radiological data to arrive at a final diagnosis. RESULTS Reports on FNAC smears were retrospectively analysed, which had been done in various anatomic sites- liver (70 cases, colon (19 cases, gallbladder (17 cases, mesenteric lymph nodes (12 cases, ovary (3 cases, adrenals (2 cases and 1 case each of pancreas, peritoneal wall, pelvic, suprapubic and flank masses. The mean age was 42.16 years with M:F of 1.3:1. The diagnostic yield was 85.2% in combination for Ultrasound Guided (USG and Computed Tomography (CT guided aspiration. The smears were classified as benign neoplastic, malignant neoplastic, non-neoplastic, inconclusive and unsatisfactory for interpretation. There were 79 (61.7% malignant neoplastic lesion, 5 (3.9% benign neoplastic lesion, 25 (19.5% non-neoplastic lesion, one (0.7% inconclusive lesions and 18 (14.1% unsatisfactory smears. The liver and the colon were the most common sites. Adenocarcinomas and Hepatocellular Carcinoma (HCC were the most common malignant lesions comprising of 35 (44.3% and 25 (31.6% of the total malignant lesions diagnosed. CONCLUSION Intra-abdominal FNA is a simple, economical and a safe procedure with high sensitivity, specificity and

    Full text: There are numerous conditions that affect mainly or exclusively the pediatric population. These constitute true emergencies, related to patient's health. Delay in diagnosis and treatment of abdominal non-traumatic emergencies may result in rapid deterioration, peritonitis, sepsis, even death or in severe complications with subsequent morbidity. Abdominal emergencies in children mostly present with pain, tenderness, occasionally coupled by vomiting, fever, abdominal distension, and failure to pass meconium or stools. Diarrhea, blood per rectum, abnormal laboratory tests and lethargy may also be manifestations of acute abdominal conditions. Abdominal emergencies have a different aetiology, depending on age and whether the pain is acute or chronic. Symptoms have to be matched with age and gender. Newborns up to 1 months of age may have congenital diseases: atresia, low obstruction including Hirschsprung's disease, meconium ileus. Meconium plug is one of the commonest cause of low obstruction in newborns that may also develop necrotizing enterocolitis, incarcerated inguinal hernia and mid-gut volvulus. Past the immediate postnatal period, any duodenal obstruction should be considered midgut volvulus until proven otherwise and patients should undergo ultrasonography and/or properly performed upper GI contrast study that records the exact position of the deduno-jejunal junction. Infants 6 months-2 years carry the risk of intussusception, mid-gut volvulus, perforation, acute pyelonephritis. Preschool and school-aged children 2-12 years carry the risk of appendicitis, genito-urinary abnormalities including torsion, urachal abnormalities, haemolytic uremic syndrome and Henoch-Schonlein purpura. Children above 12 years suffer from the same conditions as in adults. Most conditions may affect any age despite age predilection. Abdominal solid organ ultrasonography (US) coupled with gastrointestinal ultrasonography is the principle imaging modality in radiosensitive

    Full Text Available PURPOSE: To study the imaging exams more commonly used for abdominal aortic aneurysms evaluation - ultrasonography, conventional computerized tomography, helical computerized tomography and nuclear magnetic angioresonance - comparing the preoperative measurements reached by those radiological methods with the measurements made during the surgical procedures. METHODS: Patients who had indication of elective transperitoneal surgical treatment for their abdominal aortic aneurysms were included in the study. The initial diagnosis of the aortic dilatation was made by ultrasonography and, after the surgical treatment was indicated, the patient was submitted to another imaging method. Sixty patients were divided into 3 groups according to the complementary imaging method (conventional computerised tomography, helical computerized tomography, nuclear magnetic angioresonance. The ultrasonography of the first 20 patients were joined in a fourth group. There were considered in the study the measurements of the transversal diameter of the proximal neck, maximum transversal diameter of the aneurysm, straight-line length and transversal diameter of the common iliac arteries given by the imaging methods. The same measurements were made by using a caliper during the surgical procedure, and then compared to the values obtained from the radiological exams. RESULTS: The maximum transverse diameter had a range measurement variation of 4.5 to 13.6 cm in the intraoperative, with no statistically significant differences when compared with all the imaging tests. The ultrasonography, however, overestimated the measurements of the proximal neck and the common iliac arteries, in comparison with intraoperative measures. The length of the aorta aneurysm obtained by the conventional computerized tomography was significantly lower if compared to the measures done with the calliper during the operation. The helical computerized tomography and the nuclear magnetic

    Full Text Available OBJETIVO: O objetivo deste estudo é avaliar a variabilidade interobservador do método ultrassonográfico para medida da gordura subcutânea, visceral e perirrenal por meio de técnica padronizada. MATERIAIS E MÉTODOS: Foram avaliados 50 pacientes entre novembro de 2006 e janeiro de 2007. A medida da espessura subcutânea foi realizada com transdutor linear de 7,5 MHz posicionado transversalmente a 1 cm acima da cicatriz umbilical. Para a gordura visceral foi utilizado transdutor de 3,5 MHz posicionado 1 cm acima da cicatriz umbilical, considerando-se a medida entre a face interna do músculo reto abdominal e a parede posterior da aorta na linha média do abdome. A gordura perirrenal foi medida no terço médio do rim direito, com transdutor posicionado na linha axilar média. RESULTADOS: A reprodutibilidade interobservador foi analisada por meio do teste t de Student, com significância de 95%. Não houve diferença significativa entre as médias das medidas das gorduras subcutânea, visceral e perirrenal, com p = 0,7141, 0,7286 e 0,6368, respectivamente.

    Endoanorectal ultrasonography (EARUS) may be used for diagnosing various anorectal disorders. EARUS is easy to perform, has a short learning curve, and causes less discomfort than routine digital examination. Anal sphincters can be clearly visualized, and one can easily distinguish between the internal (hypoechoic) and external (hyperechoic) anal sphincters. Other pelvic floor structures, like the puborectalis muscle, can also be visualized. The use of contrast agents can increase the accuracy of EARUS in the assessment of perianal fistulae. In addition, EARUS is an excellent alternative to expensive magnetic resonance imaging. Besides its use in incontinence and perianal sepsis, the presence of slight or massive submucosal invasion in early rectal cancer may be imaged in greater detail. With 3-dimensional EARUS, it is possible to diagnose the anorectal diseases, in multiplane, with high spatial resolution, adding important information about the therapeutic decision. The normal sonographic anatomy of the anorectum, sonographic findings of anorectal diseases, and indications and limitations of endosonography with complementary techniques such as transvaginal and transperineal ultrasound are reviewed in this article.

    Full Text Available History of present illness: A 69-year-old male with poorly controlled hypertension presented with 1 hour of severe low back pain that radiated to his abdomen. The patient was tachycardic and had an initial blood pressure of 70/40. He had a rigid and severely tender abdomen. The patient’s history of hypertension, abnormal vital signs, severity and location of his pain were suspicious for a ruptured abdominal aortic aneurysm (AAA. Therefore, a computed tomography angiogram (CTA was ordered. Significant findings: CTA demonstrated a ruptured 7.4 cm infrarenal abdominal aortic aneurysm with a large left retroperitoneal hematoma. Discussion: True abdominal aortic aneurysm is defined as at least a 3cm dilatation of all three layers of the arterial wall of the abdominal aorta.1 An estimated 15,000 people die per year in the US of this condition.2 Risk factors for AAA include males older than 65, tobacco use, and hypertension.1,3,4 There are also congenital, mechanical, traumatic, inflammatory, and infectious causes of AAA.3 Rupture is often the first manifestation of the disease. The classic triad of abdominal pain, pulsatile mass, and hypotension is seen in only 50% of ruptured AAAs.5 Pain (abdominal, groin, or back is the most common symptom. The most common misdiagnoses of ruptured AAAs are renal colic, diverticulitis, and gastrointestinal hemorrhage.6 Bedside ultrasonography is the fastest way to detect this condition and is nearly 100% sensitive.1 One study showed that bedside ultrasounds performed by emergency physicians had a sensitivity of .94 [95% CI = .86-1.0] and specificity of 1 [95% CI = .98-1.0] for detecting AAAs.7 CTA has excellent sensitivity (approximately 100% and yields the added benefit of facilitating surgical planning and management.1 Without surgical treatment, a ruptured AAA is almost uniformly fatal, and 50% of those who undergo surgery do not survive.1 Early resuscitation and coordination with vascular surgery should be

    Full Text Available A distrofia muscular de Duchenne (DMD é um tipo de distrofia muscular em humanos caracterizada por uma doença genética ligada ao cromossomo X. O cão golden retriever portador da distrofia muscular (GRMD tem sido intensamente estudado e considerado o modelo mais representativo para a doença observada em humanos. Assim, como forma de verificar anormalidades em órgãos internos nesses animais, foi realizado o exame ultra-sonográfico de 24 cães golden retriever saudáveis, portadores e afetados pela distrofia muscular. O exame ultra-sonográfico do GRMD diagnosticou aumento hepático de moderado a severo, incluindo os vasos hepáticos e seus ramos e aumento de ecogenicidade da vesícula biliar e vesícula urinária. Entretanto, não foram observadas imagens claras de alterações no baço e nos vasos ramos da aorta. A partir disso, acreditamos que o exame ultra-sonográfico constitui-se em um procedimento útil no acesso de órgãos abdominais em cães afetados pela distrofia muscular.Duchenne muscular dystrophy (DMD is one type of human’s muscular dystrophy characterized by a genetic disorder linked to the X chromosome. The Golden Retriever muscular dystrophic (GRMD has been extensively studied and considered the best resembling model to the human disease. Therefore, for identifying internal organs abnormality in GRMD, abdominal and pelvic ultrasonography was performed in 24 golden retriever dogs, either healthy or muscular dystrophic in different levels of disease. The GRMD ultrasonographic exams diagnosed moderate to severe liver enlargement, including hepatic vessels and their branches and increase of echogenicity in gallbladder and urinary bladder. However was not-clearly recognized pathologic images from spleen and aortic vessels were accessed. Therefore, we believe, the ultrasonographic exam was an useful procedure to the assessment of abdominal organs in dogs affected by muscular dystrophy.

    Findings of hepatic and gallbladder ultrasonography were analyzed in 12 dogs with gallbladder and/or extrahepatic biliary tract obstruction and compared with the results of exploratory laparotomy. Hepatic ultrasonography demonstrated normal liver in 2 dogs and hepatic abnormalities in 10 animals. The following ultrasonographic diagnoses were established compared to surgical findings: gallbladder obstruction caused by bile sludge (correct/incorrect: 1/2, surgical diagnosis: choleliths in one case), gallbladder obstruction caused by neoplasm (0/1, surgical diagnosis: mucocele), gallbladder and extrahepatic biliary tract obstruction due to choleliths (3/3), extrahepatic biliary tract obstruction caused by pancreatic mass (1/1) and small intestinal volvulus (1/1). Bile peritonitis caused by gallbladder rupture (4/4) was correctly diagnosed by ultrasound, aided with ultrasonographically-guided abdominocentesis and peritoneal fluid analysis. Rupture of the gallbladder should be suspected in the presence of a small, echogenic gallbladder or in the absence of the organ together with free abdominal fluid during ultrasonography. Laparotomy was correctly indicated by ultrasonography in all cases. However, the direct cause of obstruction could not be determined in 2 of the 12 dogs by ultrasonography alone.

    Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition. Copyright © 2016 SERAM.

    1991-01-01

    The present study was performed to compare the clinical value of urography and ultrasonography in a non-selected group of patients referred for urography to a university hospital. The conslusions and clinical implications of the study are as follows: Intravenous urography remains the cornerstone imaging examination in the evaluation of ureteral calculi. Ultrasonography is a valuable adjunct in cases of non- visualization of the kidneys, in distal obstruction and known contrast media allergy. When women with recurrent urinary tract infection are referred for imaging of the urinary tract, ultrasonography should be used. Ultrasonography should replace urography for screening of non-acute hydronephrosis like in female genital cancer and benign prostate hyperplasia. There is good correlation between urography and ultrasonography in assessing the degree of hydronephrosis. However, more researh on the relationship between hydronephrosis and obstruction is necessary. Ultrasonography should be used as the only imaging method of the upper urinary tract in patients with microscopic hematuria. In patients less than 50 years with macroscopic hematuria, ultrasonography should be used as the only imaging of the upper urinary tract, and an examination of the urinary bladder should be included. In patients over 50 years, urography supplied with ultrasonography should be used, but more research is necessary on the subject of imaging method and age. 158 refs

    Intestinal tuberculosis is generally diagnosed using conventional barium studies, however recent diagnostic modalities such as ultrasonography and CT scan are widely applicated in conjunction with conventional studies for the search of lymph node presentation and associated extra-intestinal organs. It is important to differentiate intra-abdominal tuberculosis from metastatic or lymphomatous disease clinically. And it might be especially of worth to find out if there is any differential point between tuberculosis and other lymph nodal disease entities when we meet similar findings on imaging modalities. Authors have tried to evaluate ultrasonographic findings in conjunction with other studies in nine cases of abdominal tuberculosis which showed mainly extra-intestinal and/or lymph nodal involvement

    Full Text Available The coexistence of intrauterine and extrauterine pregnancy, the heterotopic pregnancy, is a rare obstetric phenomenon. The preoperative diagnosis of this condition is very difficult; leading to a higher maternal morbidity and fetal loss. We experienced a case of intrauterine pregnancy and ruptured abdominal pregnancy implanted on the illeocaecal region in a 26-year-old primiparous woman. She was clinically misdiagnosed as a case of ruptured ectopic pregnancy, but ultrasonography showed it to be a case of heterotopic pregnancy. Subsequently, the patient was subjected to laparotomy and the ruptured abdominal pregnancy was evacuated. She continued with the intrauterine pregnancy till term and delivered a healthy female baby. Although this condition is unusual, any general surgeon in the emergency department must be aware of this complication and its management, which is often initially misdiagnosed.

As often initial imagine method in abdominal complaints, nowadays has TUS much better diagnostic potential than two decades ago. High-resolution ultrasound probes with harmonic imaging significantly improve resolution of bowel wall in real time, with possibility to asses bowel peristalsis. Color flow doppler enables evaluation of intramural bowel vascularisation, pulse wave doppler helps to quantificate flow in coeliac and superior mesenteric arteries. Small intestine contrast ultrasonography with oral contrast fluid, as well as contrast enhanced ultrasonography with intravenous microbubble contrast also improves small bowel imaging. We present a review of small intestine pathology that should be detected during ultrasound examinations, discuss technical requirements, advantages and limitations of TUS, typical ultrasound signs of Crohn's disease, ileus, celiac disease, intussusception, infectious enteritis, tumours, ischemic and haemorrhagic conditions of small bowel. In the hands of experienced investigator, despite some significant limitations(obesity, meteorism, is transabdominal ultrasonography reliable, noninvasive and inexpensive alternative method to computerised tomography (CT and magnetic resonance imaging (MRI in small bowel examination.

    For the diagnostics of nerve lesions an imaging method is necessary to visualize peripheral nerves and their surrounding structures for an etiological classification. Clinical neurological and electrophysiological investigations provide functional information about nerve lesions. The information provided by a standard magnetic resonance imaging (MRI) examination is inadequate for peripheral nerve diagnostics; however, MRI neurography is suitable but on the other hand a resource and time-consuming method. Using ultrasonography for peripheral nerve diagnostics. With ultrasonography reliable diagnostics of entrapment neuropathies and traumatic nerve lesions are possible. The use of ultrasonography for neuropathies shows that a differentiation between different forms is possible. Nerve ultrasonography is an established diagnostic tool. In addition to the clinical examination and clinical electrophysiology, structural information can be obtained, which results in a clear improvement in the diagnostics. Ultrasonography has become an integral part of the diagnostic work-up of peripheral nerve lesions in neurophysiological departments. Nerve ultrasonography is recommended for the diagnostic work-up of peripheral nerve lesions in addition to clinical and electrophysiological investigations. It should be used in the clinical work-up of entrapment neuropathies, traumatic nerve lesions and spacy-occupying lesions of nerves. (orig.)

    56 cases of ultrasonography in patient with proven pelvic mass were reviewed. Ultrasonography is a very useful noninvasive diagnostic modality in the patient with clinically suspected pelvic masses giving accurate assessment of the size, location, internal structure and origin as well as its existence. A specific diagnosis was possible in selected patients with ovarian cystadenoma, dermoids, uterine myoma, and H-mode. Nonspecific pattern was common in pelvic abscess and ectopic pregnancy. Diagnostic errors were primarily due to small lesions (2 cm or less in diameter) or misinterpretation of the lesion.

    Five cases of recurrent pyogenic cholangitis (RPC) were studied by ultrasonography, computed tomography (CT), and cholangiography. All patients were recent immigrants from the Orient or Indonesia and had had recurrent attacks of cholangitis for many years. The bile was infected by E. coli and the biliary ducts were dilated; in addition, extrahepatic bile-pigment calculi we represent in all 5 and intrahepatic calculi in 4. Abdominal ultrasound usually failed to demonstrate duct calculi and extrahepatic dilatation due to the soft, mud-like consistency of the stones. CT was successful in showing the calculi and the full extent of dilatation. The authors conclude that preoperative diagnosis of RPC is best achieved by awareness of the characteristic clinical presentation and the findings on abdominal CT. Preoperative cholangiography provides excellent detail, but poses the danger of biliary sepsis requiring antibiotics

The fact that during the US study a clinical history can be obtained strongly adds to the value of the US exam. This does require investment in time and expertise and ideally a paediatric radiologist performing the exam. In this review the role of ultrasonography (US) of the liver, biliary tract and pancreas in children is discussed.

    Traumatic lumbar hernia describes the extrusion of intraperitoneal or extraperitoneal contents through a defect in the posterolateral abdominal wall caused by a trauma. This is a rare entity and usually diagnosed by computed tomography. A 64-year-old male received an injury on his cervical spinal cord after an accident in which he fell down. He complained of a mass on his left posterolateral back area. We diagnosed the mass as a traumatic lumbar hernia by ultrasonography and confirmed it by computed tomography. We conclude that the ultrasonography can be a useful diagnostic tool for traumatic lumbar hernia

    Common causes of acute abdominal pain include appendicitis, cholecystitis, bowel obstruction, urinary colic, perforated peptic ulcer, pancreatitis, diverticulitis, and nonspecific, nonsurgical abdominal pain. The topographic classification of acute abdominal pain (pain in one of the four abdominal quadrants, diffuse abdominal pain, flank or epigastric pain) facilitates the choice of the imaging technique. The initial radiological evaluation often consists of plain abdominal radiography, despite significant diagnostic limitations. The traditional indications for plain films - bowel obstruction, pneumoperitoneum, and the search of ureteral calculi - are questioned by helical computed tomography (CT). Although ultrasonography (US) is in many centers the modality of choice for imaging the gallbladder and the pelvis in children and women of reproductive age, CT is considered to be one of the most valued tools for triaging patients with acute abdominal pain. CT is particularly beneficial in patients with marked obesity, unclear US findings, bowel obstruction, and multiple lesions. The introduction of multidetector row CT (MDCT) has further enhanced the utility of CT in imaging patients with acute abdominal pain. (orig.)

    The usefulness of pulse-echo ultrasonography of the practices of obstetrics has been great. It is more reliable than many biochemical and biophysical technics that have been developed in recent years to try to improve pregnancy outcome. When carefully performed and accurately interpreted, it can supply most vital information about the status of the fetus without any known risks to both mother and the fetus itself. The main obstertricalindications of ultrasonography coule be summarized as follows. 1. Diagnosis of early pregnancy. 2. Fetal growth and its maturity. 3. Complications of pregnancy and abnormal pregnancy. a) Vaginal bleeding in early intrauterinepregnancy. b) Multiple pregnancy. c) Ectopic pregnancy d) Hydatidiform mole e) Pelvic mass complicated with pregnancy f) Fetal anomaly 4. Fetal presenation and attitude 5. Placentography

    To compare Doppler ultrasonography with laboratory tests in evaluation of diabetic nephropathy. Fifty-five patients (mean age = 60, M : F = 26 : 29) with diabetes mellitus underwent renal Doppler ultrasonography. Resistive indices were compared with degree of proteinuria, serum creatinine level, and creatinine clearance rate. Eighteen patients who showed no proteinuria or microscopic proteinuria had a mean resistive index (RI) of 0.72 (SD, 0.05), 16 patients with macroscopic proteinuria without nephrotic syndrome had a mean RI of 0.82 (SD, 0.13), and 21 patients with nephrotic syndrome had a mean RI of 0.90 (SD, 0.12). Renal RI correlated highly with serum creatinine level (r = 0.62) and creatinine clearance rate (r = -0.43). Renal Doppler ultrasonography provides a useful indication of renal function in diabetic nephropathy but cannot offer an advantage over conventional laboratory test

    to compare the intra and interobserver reproducibility of the total thickness measurement of the inferior uterine segment (IUS), through the abdominal route, and of the muscle layer measurement, through the vaginal route, using bi and tridimensional ultrasonography. the IUS thickness measurement of 30 women, between the 36th and 39th weeks of gestation with previous caesarean section, done by two observers, was studied. Abdominal ultrasonography with the patient in both supine and lithotomy position was performed. In the sagittal section, the IUS was identified and four bidimensional images and two tridimensional blocks of the total thickness were collected through the abdominal route, and the same for the muscle layer, through the vaginal route. Tridimensional acquisitions were manipulated in the multiplanar mode. The time was measured with a chronometer. Reproducibility was evaluated by the computation of the absolute difference between measurements, the ratio of differences smaller than 1 mm, the intraclass coefficient (ICC), and the Bland and Altman's concordance limits. the average bidimensional measurement of IUS thickness was 7.4 mm through the abdominal and 2.7 mm through the vaginal route, and the tridimensional measurement was 6.9 mm through the abdominal and 5.1 mm through the vaginal route. Intra- and interobserver reproducibility of vaginal versus abdominal route: smaller absolute difference (0.2-0.4 mm versus 0.8-1.5 mm), greater ratio of differences (85.8-97.8% versus 48.7-72,8%), with p0.05[A1] and similar lower concordance limits (-38 to 3.4 versus -3.6 to 4 mm) for tridimensional ultrasonography and ICC (0.6-0.9 versus 0.7-0.9). from the above, we came to the conclusion that the measurement of the IUS muscle layer, through the vaginal route using tridimensional ultrasonography is more reproducible. Nevertheless, our results do not indicate that this measurement shows any clinical evidence to predict uterine tear, as that was not the aim of this

    Janaína Luz Narciso-Schiavon

    Full Text Available CONTEXT AND OBJECTIVE: The main causes of hepatic steatosis (HS are alcoholic liver disease and nonalcoholic fatty liver disease (NAFLD. Although liver biopsy is the gold standard for NAFLD diagnosis, the finding of abnormal aminotransferases in abstinent individuals, without known liver disease, suggests the diagnosis of NAFLD in 80-90% of the cases. Identification of clinical factors associated with HS on abdominal ultrasound may enable diagnoses of fatty liver non-invasively and cost-effectively. The aim here was to identify clinical variables associated with HS in individuals with elevated alanine aminotransferase (ALT levels. DESIGN AND SETTING: Cross-sectional study in a single tertiary care center. METHODS: Individuals with elevated ALT, serologically negative for hepatitis B and C, were evaluated by reviewing medical files. Patients who did not undergo abdominal ultrasonography were excluded. RESULTS: Among 94 individuals included, 40% presented HS on ultrasonography. Compared with individuals without HS, those with fatty liver were older (P = 0.043, with higher body mass index (BMI (P = 0.003, diabetes prevalence (P = 0.024, fasting glucose levels (P = 0.001 and triglycerides (P = 0.003. Multivariate analysis showed that BMI (odds ratio, OR = 1.186; 95% confidence interval, CI: 1.049-1.341; P = 0.006 and diabetes mellitus (OR = 12.721; 95% CI: 1.380-117.247; P = 0.025 were independently associated with HS. CONCLUSIONS: Simple clinical findings such as history of diabetes and high BMI may predict the presence of HS on ultrasonography in individuals with elevated ALT and negative serological tests for hepatitis.

    Fatty liver is one of the most commonly found disease by abdominal ultrasonography. The status of fatty liver is classified into mild, moderate and severe degrees. The study was conducted to investigate the clinical significance of fatty liver using ultrasonography. Test set consisted of 2,185 patients who visited D healthcare center in Daejeon to receive an abdominal ultrasonic test from January to December 2007. Out of the 2185 patients, 524 patients was diagnosed as fatty liver (290 male and 234 female patients). They were divided into three groups, group I for mild degree. II for moderate degree, and III for severe degree, depending on the echo of liver parenchyma, the sound attenuation, and the visibility of intrahepatic blood vessels and diaphragm. Then the correlation of obesity indices, liver function tests and metabolic syndrome was analyzed for males and females separately. As for the degree of fatty liver, 350 cases (66.8%) were classified as group I, 153 cases (29.2%) as group II, and 21 cases (4.1%) as group III. In addition, severe degree of fatty liver was more frequently found in males than in females. The mean ages of three groups for males were 46.1, 44.5, and 39.1, and those for females were 48.8, 50.2, 52.4, respectively. Males with lower mean ages have severely of fatty liver for both males and females. The results in this study show that the classification into three degrees of fatty liver in ultrasonography practice is helpful to treat and observe the progress of fatty liver. In addition, careful examination is required to measure the severity of fatty liver as well as detection of it. A standardized method to classify the degree of fatty liver is also needed for more objective measurement.

    To suggest a lexicon for liver ultrasonography and to identify radiologic features indicative of benign or malignant lesions on surveillance ultrasonography. This retrospective study included 188 nodules (benign, 101; malignant, 87) from 175 at-risk patients identified during surveillance ultrasonography for hepatocellular carcinoma. We created a lexicon for liver ultrasonography by reviewing relevant literature regarding the ultrasonographic features of hepatic lesions. Using this lexicon, two abdominal radiologists determined the presence or absence of each ultrasonographic feature for the included hepatic lesions. Independent factors associated with malignancy and interobserver agreement were determined by logistic regression analysis and kappa statistics, respectively. Larger tumor size (odds ratio [OR], 1.12; 95% confidence interval [CI], 1.06-1.183; P ultrasonography (US) features might be suggestive of malignancy. We propose a lexicon that may be useful for surveillance US.

    Ultrasonography (US) is as an important tool for differentiation of obstructive and non-obstructive causes of jaundice in infants and children. Beyond two weeks of age, extrahepatic biliary atresia and neonatal hepatitis are the two most common causes of persistent neonatal jaundice: differentiation of extrahepatic biliary atresia, which requires early surgical intervention, is very important. Meticulous analysis should focus on size and configuration of the gallbladder and anatomical changes of the portahepatis. In order to narrow the differential diagnosis, combined approaches using hepatic scintigraphy, MR cholangiography, and, at times, percutaneous liver biopsy are necessary. US is useful for demonstrating choledochal cyst, bile plug syndrome, and spontaneous perforation of the extrahepatic bile duct

    Full Text Available Background: Abdominal tuberculosis remains the great mimic despite years of experience and awareness. Reliable epidemiological data on abdominal tuberculosis are lacking in India. Objectives: To define the most suggestive clinical features of abdominal tuberculosis, to evaluate the usefulness of the normally available investigations, and the response of anti-tuberculous drugs. Study Design: Retrospective study. Materials and Methods: Out of 110 patients attending our hospital between July 2000 and June 2002, with clinical suspicion of abdominal tuberculosis, 46 patients had confirmed abdominal tuberculosis. Their clinico-radiological and cyto / histopathological profiles, side effects of anti-tuberculous drugs, and the outcome of the treatment were analyzed. Results: Weight loss, abdominal pain, and bowel disturbances were the most common symptoms. Anemia and under- nutrition, abdominal tenderness, ascites, and hepato / splenomegaly were the most common findings. Chest radiography showed active or healed tuberculous focus in 16. Ultrasonography revealed abdominal lymphadenopathy, ascites, and mass lesions in 26, 12, and four patients, respectively. Barium examination showed abnormality in eight patients out of 18, among whom it was performed. An ascitic fluid study done in 12 patients showed high adenosine deaminase in all, and positive acid fast bacilli in one. Laparoscopic peritoneal biopsy was done in18 patients, and 13 showed tuberculous granuloma. Treatment success was achieved in 38 patients with anti-tuberculous drugs. Most patients tolerated the anti-tuberculous drugs well. Conclusion: With good clinical examination and appropriate investigations definitive diagnosis of abdominal tuberculosis can be reached in a significant number of patients. Strongly suggestive clinical and laboratory data are also indications for anti-tuberculous therapy in an endemic country like India. Anti-tuberculous drugs are well tolerated and highly effective.

    Full Text Available The authors present the clinical case of a 14-year old girl with weight loss, anorexia, epigastric abdominal pain and postprandial vomiting with 5 months duration. There was a background of trichophagia for 2 years without evidence of alopecia or psychiatric history. The physical examination revealed an epigastric mass motionless, stony, with poorly defined limits, painful on palpation and about 7 cm diameter. Abdominal ultrasonography showed thickening of the gastric wall and antrum with gastric distension. The abdominal tomography scan and endoscopic examination revealed the presence of a bulky trichobezoar occupying almost the entire gastric lumen. It was decided to undergo gastrotomy and extraction of the bezoar. The postoperative period was uneventful.

    We report a case of a 77-year-old female who was admitted to the emergency department complaining of diffuse abdominal pain for five days, associated with nausea, vomiting and constipation. Physical examination disclosed a large incarcerated umbilical hernia, which was readily apparent on supine abdominal plain films. These also showed a calcified heterogeneous mass in the mid-abdominal region, which was further characterized by CT as a lithopedion (calcified ectopic pregnancy). This is one of the few cases studied on a MDCT equipment, and it clearly enhances the post-processing abilities of this imaging method which allows diagnostic high-quality MIP images. Lithopedion is a rare entity, with less than 300 cases previously described in the medical literature. However, many reported cases corresponded to cases of skeletonization or collections of fetal bone fragments discovered encysted in the pelvic region at surgery or autopsy. It is thus estimated that true lithopedion is a much rarer entity. The diagnosis may be reached by a suggestive clinical history and a palpable mass on physical examination, while the value of modern cross-sectional techniques is still virtually unknown. Ultrasonography may depict an empty uterine cavity and a calcified abdominal mass of non-specific characteristics, and computed tomography or magnetic resonance imaging are able to reach a conclusive diagnosis and may additionally define the involvement of adjacent structures. The differential diagnosis includes other calcified pathologic situations, including ovarian tumors, uterine fibroids, urinary tract neoplasms, inflammatory masses or epiploic calcifications

    The role of transabdominal muscles (external oblique, internal oblique and transversus abdominis) on core stability has been shown previously. Energy restricted diet and abdominal resistance training are commonly used by overweight and obese people to reduce their weight. In this study we investigated the impact of 12 weeks concurrent energy restricted diet and abdominal resistance training on the thickness of the lateral abdominal muscles of 19 obese and overweight women employing ultrasonography in resting and drawing-in maneuvers. The results showed significant increase of the muscle thicknesses during drawing-in maneuver after 12 weeks intervention. Based on our findings, it can be concluded that 12 weeks concurrent abdominal resistance training and energy restricted diet in addition to weight loss lead to improvement of transabdominal muscles thickness in obese and overweight people. Considering the role of these muscles in core stability, using this therapeutic protocol in obese people, particularly in those who have weakness of these muscles might be helpful.

    Anastomotic leak is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. We hypothesized that the infection-induced inflammatory response may induce overexpression of tumour progression-related genes in immune cells. The aim was to investigate the effect of postoperative intra-abdominal infection on the gene expression patterns of peripheral blood leucocytes (PBL) after surgery for colorectal cancer. Prospective matched cohort study. Patients undergoing surgery for colorectal cancer were included. Patients who had anastomotic leak or intra-abdominal abscess were included in the infection group (n = 23) and matched with patients without complications for the control group (n = 23). PBL were isolated from postoperative blood samples. Total RNA was extracted and hybridized to the Affymetrix Human Gene 1.0 ST microarray. Patients in the infection group displayed 162 upregulated genes and 146 downregulated genes with respect to the control group. Upregulated genes included examples coding for secreted cytokines involved in tumour growth and invasion (S100P, HGF, MMP8, MMP9, PDGFC, IL1R2). Infection also upregulated some proangiogenic genes (CEP55, TRPS1) and downregulated some inhibitors of angiogenesis (MME, ALOX15, CXCL10). Finally, some inhibitors (HP, ORM1, OLFM4, IRAK3) and activators (GNLY, PRF1, FGFBP2) of antitumour immunity were upregulated and downregulated, respectively, suggesting that the inflammatory environment caused by a postoperative infection favours immune evasion mechanisms of the tumour. Analysis of PBL shows differential expression of certain tumour progression-related genes in colorectal cancer patients who have a postoperative intra-abdominal infection, which in turn may promote the growth of residual cancer cells to become recurrent tumours.

    To improve the prognosis of patients with abdominal trauma. Between January 1993 and December 2005, 415 patients were enrolled in this research. The patients consisted of 347 males and 68 females with mean age of 36 years (ranging from 3-82 years). All abdominal traumas consisted of closed traumas (360 cases, 86.7%) and open traumas (55 cases, 13.3%). A total of 407 cases (98.1%) were fully recovered from trauma and the other 8 cases (1.9%) died of multiple injuries. The mean injury severity score (ISS) of all patients was 22 while the mean ISS of the patients who died in hospital was 42. Postoperative complications were seen in 9 patients such as infection of incisional wounds (6 cases), pancreatic fistula (2 cases) and intestinal fistula (1 case). All these postoperative complications were cured by the conservative treatment. Careful case history inquisition and physical examination are the basic methods to diagnose abdominal trauma. Focused abdominal ultrasonography is always the initial imaging examination because it is non-invasive and can be performed repeatedly with high accuracy. The doctors should consider the severity of local injuries and the general status of patients during the assessment of abdominal trauma. The principle of treatment is to save lives at first, then to cure the injuries. Unnecessary laparotomy should be avoided to reduce additional surgical trauma.

    conceptuses were prospectively examined. The gestational age determined by echography ranged from eight weeks and eight weeks and six days in 18 conceptuses and ten weeks and ten weeks and six days in 26 conceptuses. The following structures were analyzed by 3DUS: crown-rump length, gestational sac, amniotic sac, nuchal translucency, omphalomesenteric duct, vitellin vesicle, upper limbs, lower limbs, head-thorax distinction, lateral view of the face, coronal view of the face, ear implantation, lateral view of the spine, coronal view of the spine, and closed abdominal wall. Three blocks were obtained from each conceptus for virtual ultrasonography. Student's t test, McNemar test and kappa statistics were used for the statistical analysis. RESULTS: In group I, real multiplanar 3DUS versus 3D virtual multiplanar ultrasonography, the analysis of continuous variables showed significant differences for all variables. The analysis of categorical variables showed no significant differences in any of the variables. In group II, real volumetric 3DUS versus virtual volumetric ultrasonography, showed significant differences only for ear implantation. The results of the analyses of categorical variables were consistent for most of the variables analyzed in both groups. CONCLUSION: We concluded that there is intraobserver reproducibility of virtual ultrasonography using multiplanar and volumetric reformations.

    Fibromatosis, also known as an extra-abdominal desmoid tumor, rarely occurs in the breast and is often mistaken for carcinoma, clinically and radiologically. Desmoid tumor is a monoclonal myofibroblastic neoplasm which is locally aggressive, but rarely metastasizes. We herein report a case of a 64-year-old woman who experienced two episodes of recurrence of mammary fibromatosis. The mass was initially detected by screening mammography. It appeared as an irregularly shaped mass which was confined within the mammary zone. Recurrences were excised from the right breast 10 and 17 months later. The second recurrence occurred in the subareolar area accompanied by skin thickening and showed an anechoic component on ultrasonography, which mimicked subareolar mastitis with an abscess.

    A 66-year-old man was transferred to our hospital on November 2010 owing to a diagnosis of miliary tuberculosis. Treatment was initially started with INH, RFP, PZA, and EB. However, PZA and EB were discontinued because of their adverse effects. Subsequently, chest radiographic and laboratory findings gradually improved. However, the patient experienced lumbago, which exacerbated towards the end of March 2011. An abdominal CT scan showed an abdominal mass at the L3-L5 level between the abdominal aorta and lumbar vertebra. On the basis of the findings of abdominal ultrasonography, MRI, and PET-CT, infectious abdominal aortic aneurysm was highly suspected. Therefore, vascular graft replacement surgery was performed at the beginning of May 2011. The result of histopathological analysis showed the presence of acid-fast bacteria in the aneurysm and the lymph nodes around it, revealing that the aneurysm was due to systemic miliary tuberculosis. After the surgery, the patient was administered LVFX in addition to INH and RFP for 18 months and showed no recurrence.

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

  20. Transthoracic Ultrasonography for Clinicians

    Full Text Available Transthoracic ultrasonography (US has become an essential tool for respiratory, emergency, and critical care physicians. It can be performed with basic equipment and by personnel with minimum training as a modality for the evaluation of a wide range of thoracic pathologies. Its advantages include immediate application at the point of care, low cost, and lack of radiation. The main indications for transthoracic US are the qualitative and quantitative assessment of pleural effusions, pleural thickening, diaphragmatic pathology, as well as chest wall and pleural tumors. Transthoracic US is also useful in visualizing pulmonary pathologies that abut the pleura, such as pneumonic consolidation and interstitial syndromes, including pulmonary edema. Transthoracic US is more sensitive than the traditional chest radiograph in the detection of pneumothoraces, and it is useful in diagnosing skeletal abnormalities such as rib fractures. It is the ideal tool to guide transthoracic procedures, including thoracocentesis and pleural biopsy. Moreover, transthoracic US-guided procedures can be performed by a single clinician with no sedation and minimal monitoring. Transthoracic US-guided fine needle aspiration and/or cutting needle biopsy of extrathoracic lymph nodes and lesions arising from the chest wall, pleura, peripheral lung, and mediastinum are safe to perform and have a high yield in the of hands of experienced clinicians. Transthoracic US can also potentially guide the aspiration and biopsy of diffuse pulmonary infiltrates, consolidations, and lung abscesses. Moreover, transthoracic US may be used in the detection of pulmonary embolism

    Full Text Available The paper presents a description of essential equipment requirements for scrotal ultrasonography, including current ultrasound techniques, as well as a review of the most common scrotal pathologies. Patient preparation for the examination as well as ultrasound methodology for the assessment of scrotal and inguinal canal structures are discussed. The standard for scrotal ultrasound examination includes a precise B-mode evaluation, including testicular volumetric assessment performed using automatic measurement options based on the formula of a rotating ellipsoid or three measurements perpendicular to one another. Also, criteria for morphological assessment of abnormalities within testicular or epididymal parenchyma, including a precise evaluation of lesion size, delineation, shape and vascular pattern obtained with Doppler US, have been proposed. Standard assessment further includes epididymal evaluation, including epididymal size in the case of enlargement. The paper additionally discusses the method of ultrasonographic examination and describes the most common pathologies occurring within scrotal structures, including a quantitative analysis of hydrocele and other abnormal fluid reservoirs. We have also presented criteria for the assessment of varicocele as well as color and spectral Doppler flows in scrotal pathologies. Furthermore, we have proposed key components of scrotal ultrasound documentation, so that the contained data could be used to establish appropriate diagnosis, allowing for both adequate clinical management and the reproducibility of subsequent US evaluations performed by either the same or a different examiner. The most common causes of diagnostic errors have also been discussed.

    2014-12-01

    Full Text Available We report here the case of a 32-year-old man with a history of traumatic brain injury who presented with swelling of his right thigh. Soft tissue ultrasonography performed 3 days after the onset of symptoms showed a heterogeneous hyperechoic lesion with the formation of cysts and hypervascularity in the right iliopsoas abutting the surface of the femoral bone. This became a diffuse echogenic plaque with a posterior acoustic shadowing 12 days later. A diagnosis of heterotopic ossification was made on the basis of the presence of typical ultrasonographic findings and was confirmed by pathology. We emphasize that an early diagnosis of heterotopic ossification can be made with ultrasonography and can lead to early treatment.

    To compare the effect of the abdominal draw-in manoeuvre with the abdominal draw-in manoeuvre in combination with ankle dorsiflexion on changes in muscle thickness and associated muscle activity in abdominal muscles. A preliminary, randomised, controlled study. University laboratory. Forty healthy adults (18 males, 22 females) were allocated at random to the experimental group [mean age (SD) 24 (1.6) years, n=20] or the control group [mean age (SD) 24 (1.9) years, n=20]. The experimental group performed the abdominal draw-in manoeuvre in combination with ankle dorsiflexion, and the control group performed the abdominal draw-in manoeuvre alone, five times a day. Ultrasonography and electromyography were used to determine the intervention-related changes in muscle activity and the thickness of abdominal muscles during the abdominal draw-in manoeuvre or the abdominal draw-in manoeuvre in combination with ankle dorsiflexion. A significant difference was found in the thickness of the transverse abdominal muscle between the groups [mean difference 0.24 cm, 95% confidence interval (CI) 0.08 to 0.40, P=0.005. On electromyography, a significant difference was demonstrated in the amplitude of the transverse abdominal muscle contraction between the two techniques in the experimental group (mean difference 68.76 mV, 95% CI 53.16 to 84.36, P=0.000. The intra-class correlation coefficient (ICC(2,1)) showed excellent test-retest reliability of ultrasound measurement of the abdominal muscles: 0.96 (95% CI 0.85 to 0.99) for the transverse abdominal muscle, 0.87 (95% CI 0.62 to 0.98) for the internal oblique muscle and 0.77 (95% CI 0.44 to 0.96) for the external oblique muscle. This is the first study to demonstrate the additive effect of ankle dorsiflexion on deep core muscle thickness and activity, thus contributing to existing knowledge about therapeutic exercise for the effective management of low back pain.

    Full Text Available Sarah L Gans,1 Jaap Stoker,2 Marja A Boermeester11Department of Surgery, 2Department of Radiology, Academic Medical Center, University of Amsterdam, Amsterdam, The NetherlandsAbstract: Several studies have demonstrated that a diagnosis based solely on a patient’s medical history, physical examination, and laboratory tests is not reliable enough, despite the fact that these aspects are essential parts of the workup of a patient presenting with acute abdominal pain. Traditionally, imaging workup starts with abdominal radiography. However, numerous studies have demonstrated low sensitivity and accuracy for plain abdominal radiography in the evaluation of acute abdominal pain as well as various specific diseases such as perforated viscus, bowel obstruction, ingested foreign body, and ureteral stones. Computed tomography, and in particular computed tomography after negative ultrasonography, provides a better workup than plain abdominal radiography alone. The benefits of computed tomography lie in decision-making for management, planning of a surgical strategy, and possibly even avoidance of negative laparotomies. Based on abundant available evidence, major advances in diagnostic imaging, and changes in the management of certain diseases, we can conclude that there is no place for plain abdominal radiography in the workup of adult patients with acute abdominal pain presenting in the emergency department in current practice.Keywords: abdominal x-ray, acute abdomen, acute abdominal pain, emergency department, diagnostic imaging, abdominal radiography

  10. [Abdominal catastrophe--surgeon's view].

    Vyhnánek, F

    2010-07-01

    Abdominal catastrophe is a serious clinical condition, usually being a complication arising during treatment of intraabdominal nontraumatic disorders or abdominal injuries. Most commonly, inflamation- secondary peritonitis, is concerned. Abdominal catastrophe also includes secondary signs of sepsis, abdominal compartment syndrome and enterocutaneous fistules. Most septic abdominal disorders which show signs of abdominal catastrophy, require surgical intervention and reinterventions--planned or "on demand" laparotomies. During the postoperative period, the patient requires intensive care management, including steps taken to stabilize his/hers condition, management of sepsis and metabolic and nutritional support measures, as well as adequate indication for reoperations. New technologies aimed at prevention of complications in laparostomies and to improve conditions for final laparotomy closure are used in phase procedures for surgical management of intraabdominal infections. Despite the new technologies, abdominal catastrophe has higher morbidity and lethality risk rates.

  11. General principles of carotid Doppler ultrasonography

    Lee, Whal [Dept. of Radiology, Seoul National University College of Medicine, Seoul (Korea, Republic of)

    2014-03-15

    Carotid Doppler ultrasonography is a popular tool for evaluating atherosclerosis of the carotid artery. Its two-dimensional gray scale can be used for measuring the intima-media thickness, which is very good biomarker for atherosclerosis and can aid in plaque characterization. The plaque morphology is related to the risk of stroke. The ulceration of plaque is also known as one of the strong predictors of future embolic event risk. Color Doppler ultrasonography and pulse Doppler ultrasonography have been used for detecting carotid artery stenosis. Doppler ultrasonography has unique physical properties. The operator should be familiar with the physics and other parameters of Doppler ultrasonography to perform optimal Doppler ultrasonography studies.

    2004-09-01

    A hundred and thirty patients (104 males, and 26 females) with suspected blunt abdominal trauma were admitted to this prospective study at Althawra hospital, Sana'a, Yemen in the period between june and december 2003. Real-time ultrasonography of the abdomen was performed in all patients. Fifty-six patients showed U/S evidence of visceral injury. Fourteen injuries of spleen, 7 had evidence of liver and 8 had renal injuries. Only eight needed a laparatomy because of cardiovascular instability and the laparatomy confirmed the ultrasound findings. The remainder were treated conservatively with good results. It is of interest that there was one ultrasonic sign of fluid in one patient who progressed well on conservative therapy. Ultrasonic signs of visceral laceration or contusion were found in patients who had 2 up to 8 sonic findings. It appears that visceral injury always gives more than two sonic signs. The remaining 33 patients only had intraperitoneal fluid, only one of them had volvulus. It is not possible to state the nature of fluid, whether it is an exudate, transudate, blood or lymph. Diagnostic peritoneal lavage would have been helpful. Seven patients died, most of them due to associated injuries, mainly head injury and cardiovascular collapse, one patient died on table and had retroperitonieal haematoma extending from pelvis to the mesentery of transverse colon and had no abdominal organ injury. The sensitivity of ultrasonography for liver was 87.5% and for spleen 100%. Ultrasonography is sensitive, safe, cost effective and non invasive method for screening patients with blunt abdominal trauma.(Author)

  13. Transvaginal ultrasonography of rectal endometriosis

    Objectives: The aim of this present study was to evaluate the interobserver variation of transvaginal ultrasonographic measurements of endometriosis infiltrating the rectosigmoid wall. Methods: Transvaginal ultrasonography was performed independently by two observers. Observer 1 had several years...... of experience in ultrasonography while observer 2 was a medical student with no prior experience in ultrasonography or endometriosis. In 24 patient length, width and depth of endometriosis infiltrating the rectosigmoid bowel was measured. The differences between the observers were analysed by Bland and Altman...... for a relatively short period gives comparable scanning results between the two observers. It seems that transvaginal ultrasound could be used as a diagnostic tool for rectal endometriosis in most departments. However, the irregular morphology of the lesions makes the measurements very complex, and a strict...

    2016-08-01

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

  15. Ultrasonography of the equine shoulder

    1996-01-01

    Six horses with shoulder injuries were presented in this report with emphasis on the use of ultrasonography vs. radiography in diagnosis. The two imaging modalities represented valuable and complementary diagnostic procedures. Two horses had fracture fragments of the lateral humeral tuberosity, the accurate ultrasonographic findings encouraging clearer radiographic identification by oblique projections. In one horseultrasonography enabled more accurate localization of calcification within the supraspinatus muscle. In the remaining three cases ultrasonography visualized distension of the bicipital bursa due to aseptic bursitis, bursal hemorrhage, or associated with injury of the biceps brachii muscle and the underlying intermediate humeral tubercle, the bony involvement more clearly demonstrated radiographically

    Spec cPL is the most sensitive and specific test for diagnosing pancreatitis in dogs. Its results have not been compared to those of the 1,2-o-dilauryl-rac-glycero-3-glutaric acid-(6'-methylresorufin) ester (DGGR) lipase assay or those of abdominal ultrasonography. To investigate agreement of Spec cPL with DGGR lipase activity and pancreatic ultrasonography in dogs with suspected pancreatitis. One hundred and forty-two dogs. DGGR lipase activity (reference range, 24-108 U/L) and Spec cPL were measured using the same sample. The time interval between ultrasonography and lipase determinations was pancreatic ultrasonography and the 2 tests were assessed using Cohen's kappa coefficient (κ). DGGR lipase (>108, >216 U/L) and Spec cPL (>200 μg/L) had κ values of 0.79 (95% confidence interval [CI], 0.69-0.9) and 0.70 (CI, 0.58-0.82). DGGR lipase (>108, >216 U/L) and Spec cPL (>400 μg/L) had κ values of 0.55 (CI, 0.43-0.67) and κ of 0.80 (CI, 0.71-0.9). An ultrasonographic diagnosis of pancreatitis and DGGR lipase (>108, >216 U/L) had κ values of 0.29 (CI, 0.14-0.44) and 0.35 (CI, 0.18-0.52). Ultrasonographically diagnosed pancreatitis and Spec cPL (>200, >400 μg/L) had κ values of 0.25 (CI, 0.08-0.41) and 0.27 (CI, 0.09-0.45). Although both lipase assays showed high agreement, agreement between ultrasonography and lipase assays results was only fair. Because lipase results are deemed more accurate, ultrasonography results should be interpreted carefully. Copyright © 2014 by the American College of Veterinary Internal Medicine.

    Full Text Available Fascioliasis is a worldwide zoonotic infection with Fasciola hepatica and Fasciola gigantica. The zoonoses are particularly endemic in sheep-raising countries and are also endemic in Iran. Typical symptoms that may be associated with fascioliasis can be divided by phases of the disease, including the acute or liver phase, the chronic or biliary phase, and ectopic or pharyngeal fascioliasis. Cholestatic symptoms may be absent, and in some cases diagnosis and treatment may be preceded by a long period of abdominal pain, eosinophilia and vague gastrointestinal symptoms. We report a case with epigastric and upper quadrant abdominal pain for the last 4 years, with imaging suggesting cholangiocarcinoma. Considering a new concept of endoscopic ultrasonography, at last F. hepatica was extracted with endoscopic retrograde cholangiography.

    Full Text Available Ultrasonography (US is widely used to evaluate most body parts in pediatric patients because it is simple, noninvasive, easy to use, and applicable in a wide variety of clinical situations. US is the modality of choice for the initial evaluation of acute abdominal pain in pediatric patients because of their small body habitus and the presence of less fat tissue in the abdominal wall and peritoneal cavity. The most important factor in performing pediatric emergency US is the graded compression technique and selection of the proper transducer. The careful evaluation of bowel wall thickening combined with ancillary findings such as fluid collection, increased echogenicity of the mesenteric fat tissue, enlarged lymph nodes, hyperemic bowel changes, and abnormal bowel peristalsis can increase the diagnostic capability of US.

    Survey abdominal radiographs, excretory urograms, and nephrosonograms were obtained from 14 dogs with renal lesions. Renal enlargement was suspected on survey radiographs and confirmed by excretory urography in 13 dogs. Radiographic differentiation between a solid and cystic renal lesion was not possible in 9 dogs. Ultrasonography determined the presence of solid masses in 12 dogs, established the presence of a renal cyst in the opposite kidney in 1 dog, and revealed hydronephrosis in 2 dogs. Ultrasonography appeared to be more sensitive than radiography in differentiating the internal characteristics of renal lesions

    Topographic diagnosis of adrenal pheochromocytoma was determined by ultrasonography in all 6 cases studied and by radiocholesterol scintigraphy in 6 out 7 cases studied. It would appear that ultrasonography is preferable in the localization of an abdominal pheochromocytoma, whether adrenal or extra-adrenal. Intravenous urography along with rapid sequence nephrotomography and radiocholesterol scintigraphy, play a complementary role in confirming the topographic diagnosis. In case these methods prove unsuccessful or provide conflicting results, it is then possible to consider computed tomography, angiography and canal catheterization [fr

    Diagnostic ultrasound has become one of the most useful tools in the practice of obstetrics. It has been of particular utility in the placental localization. We analyzed 34 patients of placenta previa scanned by ultrasound. The results were as follows; 1. The age of patient ranged from 22 to 39 years, showing the highest incidence in 26 to 30 years. 2. The accuracy of correct localization was 70.6%. 3. Among 13 cases diagnosed by ultrasound as total placenta previa, 2 cases were partial placental previa and 1 was low-lying placenta at the time of delivery. 4. Among 9 cases diagnosed by ultrasound as partial placenta previa, 1 case was total placenta previa and 1 case was low-lying placenta and 1 case was upper segment placenta. 5. Among 10 cases diagnosed by ultrasound as low-lying placenta, 2 cases were partial placenta previa. 6. Among 2 cases diagnosed by ultrasound as upper segment placenta, 1 case was total placenta previa and 1 case was partial placenta previa. 7. Among 9 cases done serial ultrasound, 3 cases revealed that the placenta migrates toward fundus in the course of pregnancy. Therefore, the placental scanning should be repeated in the last month before term to decide the mode of delivery. Conclusively, ultrasonography is the imaging modality of choice in the evaluation of placenta localization because it provides speedy and repeatable way without any known risk to both mother and fetus itself. Careful performance and accurate interpretation should be needed for more correct placental localization.

    A case of leaking mycotic abdominal aortic aneurysm is reported, with a brief review of the literature. A 58 year old female presented with shoulder and abdominal pain associated with diarrhea, vomiting and fever with leucocytosis. Computed tomography of the abdomen showed pooling of contrast in the retroperitoneum anterior to a non-dilated abdominal aorta. There was considerable retroperitoneal blood accumulating in a mass-like lesion in the right lower abdomen and pelvis obstructing the right renal collecting system. Laparotomy revealed a 4 cm diameter saccular aneurysm of the abdominal aorta, with a 1 cm diameter neck. Culture of the thrombus grew Streptococcus pyogens. 11 refs., 2 figs

    To determine the accuracy of physical examination and ultrasonographic evaluation performed by emergency physicians in cases of blunt abdominal trauma for the early diagnosis of intraabdominal haemorrhage. In this clinical prospective study, trauma patients were evaluated with four-quadrant ultrasonography by emergency physicians after initial stabilisation and physical examination. Diagnoses based on demographic data, physical examination and emergency physician's ultrasonography were compared with the subsequent clinical course. A total of 442 patients participated in the study. The sensitivity and specificity of emergency physician's ultrasonographic examination to detect intraabdominal haemorrhage were 86 and 99%, respectively. Pre-test sensitivity and specificity of physical examination to detect intraabdominal haemorrhage were 39 and 90%, respectively. Physical examination was not a reliable method to detect intraabdominal haemorrhage in cases of blunt abdominal trauma. In contrast, abdominal ultrasonography performed by emergency physicians was a reliable diagnostic tool. Emergency physicians should be familiar with abdominal ultrasonographic examination, which should be routine in cases of blunt abdominal trauma.

    Intra-abdominal cryptococcosis was diagnosed in two young dogs. The first, an entire male border collie, was presented with vomiting. An abdominal mass detected during physical examination proved to be cryptococcal mesenteric lymphadenitis on exploratory laparotomy. The second dog, a female neutered giant schnauzer, was presented with neurological signs suggestive of encephalopathy. Intestinal cryptococcal granulomas were detected in an extensive diagnostic investigation which included abdominal ultrasonography. The gastrointestinal tract was considered the most likely portal of entry for cryptococcal organisms in both cases. Both dogs were treated using surgery and multiagent antifungal chemotherapy. The first case succumbed despite therapy, while the second dog was treated successfully as gauged by return to clinical normality and a substantial decline in the cryptococcal antigen titre which continued to fall after cessation of treatment.

    Full Text Available ABSTRACT Objective: to identify victims of blunt abdominal trauma in which intra-abdominal injuries can be excluded by clinical criteria and by complete abdominal ultrasonography. Methods: retrospective analysis of victims of blunt trauma in which the following clinical variables were analyzed: hemodynamic stability, normal neurologic exam at admission, normal physical exam of the chest at admission, normal abdomen and pelvis physical exam at admission and absence of distracting lesions (Abbreviated Injury Scale >2 at skull, thorax and/or extremities. The ultrasound results were then studied in the group of patients with all clinical variables evaluated. Results: we studied 5536 victims of blunt trauma. Intra-abdominal lesions with AIS>1 were identified in 144 (2.6%; in patients with hemodynamic stability they were present in 86 (2%; in those with hemodynamic stability and normal neurological exam at admission in 50 (1.8%; in patients with hemodynamic stability and normal neurological and chest physical exam at admission, in 39 (1.5%; in those with hemodynamic stability, normal neurological, chest, abdominal and pelvic physical exam at admission, in 12 (0.5%; in patients with hemodynamic stability, normal neurological, chest, abdominal and pelvic physical exam at admission, and absence of distracting lesions, only two (0.1% had intra-abdominal lesions. Among those with all clinical variables, 693 had normal total abdominal ultrasound, and, within this group, there were no identified intra-abdominal lesions. Conclusion: when all clinical criteria and total abdominal ultrasound are associated, it is possible to identify a group of victims of blunt trauma with low chance of significant intra-abdominal lesions.

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two

    AIM: To assess the cost-effectiveness of two population-based hepatocellular carcinoma (HCC) screening programs, two-stage biomarker-ultrasound method and mass screening using abdominal ultrasonography (AUS). METHODS: In this study, we applied a Markov decision model with a societal perspective and a lifetime horizon for the general population-based cohorts in an area with high HCC incidence, such as Taiwan. The accuracy of biomarkers and ultrasonography was estimated from published meta-analyses. The costs of surveillance, diagnosis, and treatment were based on a combination of published literature, Medicare payments, and medical expenditure at the National Taiwan University Hospital. The main outcome measure was cost per life-year gained with a 3% annual discount rate. RESULTS: The results show that the mass screening using AUS was associated with an incremental cost-effectiveness ratio of USD39825 per life-year gained, whereas two-stage screening was associated with an incremental cost-effectiveness ratio of USD49733 per life-year gained, as compared with no screening. Screening programs with an initial screening age of 50 years old and biennial screening interval were the most cost-effective. These findings were sensitive to the costs of screening tools and the specificity of biomarker screening. CONCLUSION: Mass screening using AUS is more cost effective than two-stage biomarker-ultrasound screening. The most optimal strategy is an initial screening age at 50 years old with a 2-year inter-screening interval. PMID:27022228

    Radiography and ultrasonography used together provide useful help in the clinical exploration of spleen and of abdominal lymphatic node abnormalities. These organs are difficult to examine by other techniques. Examination by radiography and ultrasonography often allows the abnormality to be localized and described, to visualize its spread and to observe its extension to other organs. Although these examinations do not allow this aspect they are invaluable in effective diagnosis. The information provided by these studies should avoid some exploratory laparotomies, to prepare for future surgical operations, to help in the prognostic (observation of metastasis,..), even to complete direct visual pre-operation examination (intra-hepatic metastasis)

    Full Text Available Ectopic hepatocellular carcinoma (HCC is a very rare clinical entity that is defined as HCC arising from extrahepatic liver tissue. This report presents a case of ectopic multiple HCC arising in the abdominal cavity. A 42-year-old otherwise healthy male presented with liver dysfunction at a general health checkup. Both HCV antibody and hepatitis B surface antigen were negative. Laboratory examination showed elevations in serum alpha-fetoprotein and PIVKA-II. Ultrasonography and computed tomography revealed multiple nodular lesions in the abdominal cavity with ascites without a possible primary tumor. Exploratory laparoscopy was performed, which revealed bloody ascites and multiple brown nodular tumors measuring approximately 10 mm in size that were disseminated on the perineum and mesentery. A postoperative PET-CT scan was performed but it did not reveal any evidence of a tumor in the liver. The tumors resected from the peritoneum were diagnosed as HCC. The present case of HCC was thought to have possibly developed from ectopic liver on the peritoneum or mesentery.

    This study was conducted to retrospectively evaluate the pattern of contrast enhancement with SonoVue on gray-scale ultrasonography of hepatic angiomyolipoma (HAML). Imaging features of 33 pathologically proven HAML lesions in 33 patients who underwent baseline ultrasound and contrast-enhanced ultrasonography (CEUS) were assessed retrospectively. All lesions were enhanced in the arterial phase and showed whole-tumor filling in. Thirty-two of 33 (97%) lesions showed early positive enhancement in the arterial phase. Twenty-three of these exhibited isoechoic or hyperechoic features in the portal phase. HAML demonstrate characteristic manifestations with SonoVue-enhanced real-time gray-scale ultrasonography.

    To analyze the ultrasonography findings in abdomen in the AIDS patients in our hospital, as well as the indications for this exploration, assessing the role of abdominal ultrasound (AU). The ultrasonographic and clinical findings in 527 patients who underwent a total of 715 explorations between 1992 and 1996 were studied. Hepatomegaly and/or splenomegaly, usually homogeneous, were observed in nearly half of the studies (45%); one third of the patients with marked splenomegaly presented visceral leishmaniasis. Focal lesions in liver and/or spleen, corresponding to angiomas, abscesses, lymphomatous lesions and metastasis, were detected in 5.7% of the explorations. Thirty-five percent of the AU revealed the presence of lymphadenopathy; nodes measuring over 2.5 cm were usually related to potential treatable infection or neoplasm. Thickening of the gallbladder wall did not usually indicate the presence of acute cholecystitis unless Murphy''s sign was also detected. Bile duct dilation and wall thickening was related to opportunistic cholangitis, and the increase in the echogenicity of the renal parenchyma was linked to AIDS-related nephropathy. Despite the fact that many of findings with AU are nonspecific, we consider that this approach should be the principal diagnostic technique in AIDS patients with suspected abdominal pathology or fever of unknown origin.

    Luciana Mendes de Oliveira Cerri

    Full Text Available The use of intraoperative ultrasonography (IOUS to evaluate liver, bile ducts and pancreatic disease, as compared to the results of preoperative ultrasonography and CT, is discussed. Forty-two patients who underwent abdominal surgery for suspected hepatobiliary and/or pancreatic disease were studied. The intraoperative study was carried out with a portable apparatus (Aloka 500, Japan, using 5.0 MHz and 7.5 MHz linear sterile transducers. The main indications for IOUS were the search for and/or evaluation of primary hepatic masses,hepatic abscesses or metastases, obstructive jaundice, or neuroendocrine tumors. In 15 cases (38.5 percent from the hepatobiliary group and in 7 cases (58.3 percent from the pancreatic group, a difference between preoperative and intraoperative findings was observed. The main difference was observed in relation to the number and size of hepatic and pancreatic lesions. The relationship between the lesions and the vascular structures was evaluated through IOUS. The method was also used to guide surgical procedures such as biopsies, the alcoholization of nodules, and the drainage of abscesses. IOUS plays an important role in detecting small hepatic and pancreatic nodules, in the assessment of anatomical relationships between the lesions and the vascular structures, and in the performance of interventionist procedures.

    A cross-sectional study was performed on acutely vomiting dogs to compare the accuracy of radiography and ultrasonography for the diagnosis of small-intestinal mechanical obstruction and to describe several radiographic and ultrasonographic signs to identify their contribution to the final diagnosis. The sample population consisted of 82 adult dogs and small-intestinal obstruction by foreign body was confirmed in 27/82 (33%) dogs by surgery or necropsy. Radiography produced a definitive result (obstructed or not obstructed) in 58/82 (70%) of dogs; ultrasonography produced a definitive result in 80/82 (97%) of dogs. On radiographs, a diagnosis of obstruction was based on detection of segmental small-intestinal dilatation, plication, or detection of a foreign body. Approximately 30% (8/27) of obstructed dogs did not have radiographic signs of segmental small-intestinal dilatation, of which 50% (4/8) were due to linear foreign bodies. The ultrasonographic diagnosis of small-intestinal obstruction was based on detection of an obstructive lesion, sonographic signs of plication or segmental, small-intestinal dilatation. The ultrasonographic presence or absence of moderate-to-severe intestinal diameter enlargement (due to lumen dilatation) of the jejunum (>1.5 cm) was a useful discriminatory finding and, when present, should prompt a thorough search for a cause of small-intestinal obstruction. In conclusion, both abdominal radiography and abdominal ultrasonography are accurate for diagnosing small-intestinal obstruction in vomiting dogs and either may be used depending on availability and examiner choice. Abdominal ultrasonography had greater accuracy, fewer equivocal results and provided greater diagnostic confidence compared with radiography. © 2010 Veterinary Radiology & Ultrasound.

    The aim of this study is to compare ultrasonography with CT in the diagnosis of nasal bone fractures. 40 patients (9 female and 31 male) with mid-facial fractures, which were suspected nasal bone fractures, were included. All of the patients had mid-facial CT images. Ultrasonography with a 7.5 MHz transducer (Aloka 3500, Tokyo, Japan) was used to evaluate the nasal bone fractures. All of the sonograms were compared with CT findings for sensitivity, specificity and predictive values. A χ(2) test was applied to the data to assess statistical significance. CT diagnosed nasal bone fractures in 24 of the 40 patients (9 unilateral fractures and 15 bilateral fractures) while ultrasonography diagnosed the fractured bones in 23 patients (9 unilateral fractures and 14 bilateral fractures). Ultrasonography missed one fractured bone in a bilateral fractured case and a unilateral fracture was also missed (two false-negative results). The sensitivity and specificity of ultrasonography in assessing nasal bone fracture in comparison with CT were 94.9% and 100%, respectively. The positive predictive value (PPV) and the negative predictive value (NPV) of ultrasonographic evaluation of the nasal bone fractures were 100% and 95.3%, respectively. The χ(2) test did not show any significant difference between CT and ultrasonography in diagnosis of nasal bone fractures (P = 0.819). Ultrasonography can be used as a first line of diagnostic imaging for evaluating nasal bone fractures, especially in children and pregnant women.

    Ultrasonography has been increasingly utilised to aid the understanding and management of rheumatic conditions. In recent years there has been a focus on the validity and utility of ultrasonography in demonstrating joint pathology, although this has largely focused on inflammatory arthritis. To undertake a systematic review of the published literature evaluating ultrasonography as an assessment tool in osteoarthritis. Medline and Pubmed were searched to identify original manuscripts, published before June 2008, utilising ultrasonography to assess the joints of cohorts of subjects with osteoarthritis. Data were extracted from manuscripts meeting the inclusion criteria, with a particular focus on the pathology imaged, the definitions used, scoring systems and their metric properties. Forty-seven studies were identified that utilised ultrasonography to assess structural pathology in osteoarthritis. Doppler function was only assessed in 10 studies and contrast agents in one. There was heterogeneity with regard to the pathology examined, the definition of pathology, quantification and the reporting of these factors. There was also a lack of construct and criterion validity and data demonstrating reliability and sensitivity to change. Whereas there is increasing evidence of the validity of ultrasonography in detecting structural pathology in inflammatory arthritis, more work is required to develop standardised definitions of pathology and to demonstrate the validity of ultrasonography in osteoarthritis.

    Full Text Available La distensión abdominal es un síntoma común, siendo en general la presentación inicial de enfermedades sistémicas o desórdenes gastrointestinales. Otras causas son infrecuentes. Los quistes del cordón espermático son poco frecuentes, pero aún más su ubicación intraabdominal, su tamaño habitual es insuficiente para producir distensión. El paciente presentado en este caso es un varón con criptorquidia bilateral admitido por distensión abdominal, interpretada inicialmente como síndrome ascítico edematoso. La ecografía interpretó la distensión como ascitis tabicada, y la tomografía computada como debida a un gran quiste. En la exploración quirúrgica se diagnosticó un quiste gigante del cordón espermático de ubicación abdominal.Abdominal distention is a frequent symptom, being often the initial presentation of systemic diseases or gastrointestinal disorders. Other causes are uncommon. Spermatic cord cysts are infrequent, abdominal location is even rarer, and the size of the cysts is usually not enough to produce abdominal distention. In our case a man with bilateral cryptorchidism was admitted with abdominal distention and edema of the lower extremities initially interpreted as ascitic-edematous syndrome. Ultrasonography interpreted abdominal distention as septate ascites, computed tomography as a giant cyst. Exploratory surgery showed a giant spermatic cord cyst in the left spermatic cord.

    2017-05-01

    Traumatic abdominal wall hernias due to blunt abdominal trauma in pediatric patients can pose a diagnostic challenge because of spontaneous hernia reduction. Ultrasonography may be superior to computed tomography for this indication in some cases because of the ability to dynamically and repeatedly assess the area of injury. Herniation can be induced or exaggerated via Valsalva maneuvers, which can facilitate its detection during dynamic assessment. We present the case of a 3-year-old boy who sustained blunt abdominal trauma, with a resultant abdominal wall hernia that was diagnosed using point-of-care ultrasound imaging. This hernia was not visualized with computed tomography, and point-of-care ultrasonography expedited admission for operative repair.

    Full Text Available Juvenile spondyloarthropathies are mainly manifested by symptoms of peripheral arthritis and enthesitis. Early involvement of sacroiliac joints and spine is exceptionally rare in children; this usually happens in adulthood. Conventional radiographs visualize late inflammatory lesions. Early diagnosis is possible with the use of ultrasonography and magnetic resonance imaging. The first part of the article presented classifications and radiographic presentation of juvenile spondyloarthropathies. This part discusses changes seen on ultrasonography and magnetic resonance imaging. In patients with juvenile spondyloarthropathies, these examinations are conducted to diagnose inflammatory lesions in peripheral joints, tendon sheaths, tendons and bursae. Moreover, magnetic resonance also shows subchondral bone marrow edema, which is considered an early sign of inflammation. Ultrasonography and magnetic resonance imaging do not show specific lesions for any rheumatic disease. Nevertheless, they are conducted for early diagnosis, treatment monitoring and identifying complications. This article presents a spectrum of inflammatory changes and discusses the diagnostic value of ultrasonography and magnetic resonance imaging.

    The purpose of this study was to evaluate the accuracy of ultrasonography (US) with a hand-held device for the diagnosis of acute appendicitis in the emergency room. US with a hand-held device was performed by the first author in 33 patients suspected of having appendicitis in the emergency room. From these 33 patients, 24 who subsequently underwent computed tomography (CT) or surgery were included in this study. The accuracy of US with the hand-held device for the diagnosis of acute appendicitis was evaluated based on the findings of CT or surgery. CT and surgery were performed in 22 and 12 patients, respectively. Final diagnoses were acute appendicitis (n=18), terminal ileitis (n=2), pelvic inflammatory disease (n=2), diverticulitis (n=1), and ureterolithiasis (n=1). The US yielded a sensitivity of 78% and a positive predictive value of 100%. The shortest distance between the abdominal wall and the appendix measured on CT was less than 40 mm in 11 patients. In ten (91%) of the 11 patients US with the hand-held device showed the swollen appendix. US with a hand-held device is potentially useful in the positive identification of acute appendicitis, but further investigation is needed to prove its utility in the routine diagnosis of acute appendicitis.

    Infectious disease is a common cause of acute abdomen. The diagnosis is based on clinical examination and basic laboratory tests. However, medical imaging routinely performed according to the clinical findings is frequently useful. Hepatic and splenic abscesses are correctly demonstrated by ultrasonography and computed tomography. Ultrasonography is the reference standard for the diagnosis of acute cholecystitis. The US examination is also performed for the diagnosis of appendicitis and its complications. Ultrasonography and barium enema are commonly performed for the evaluation of sigmoid diverticulitis. Computed tomography is the reference standard to determine medical or surgical procedures. (authors). 20 refs., 15 figs

    2015-02-01

    To compare the diagnostic accuracy of two-dimensional (2D) versus three-dimensional (3D) ultrasonography for the diagnosis of intrauterine device (IUD) malposition. In a prospective study, women with a history of failed IUD removal and/or ultrasonography results indicating malposition were recruited at a center in Hangzhou, China, between March 1, 2009, and September 30, 2011. All patients underwent 2D and 3D ultrasonography. Hysteroscopy, laparoscopy, or laparotomy was carried out to remove the IUDs and was considered the gold standard for diagnosing malposition. Among 130 participants, 128 (98.5%) were diagnosed with IUD malposition by hysteroscopy, laparoscopy, or laparotomy. Malposition had been correctly identified with 2D ultrasonography in 83 (64.8%) cases, and with 3D ultrasonography in 107 (83.6%) cases. The diagnostic accuracy of 3D ultrasonography was significantly better than was that of 2D ultrasonography (P<0.001). The use of 2D ultrasonography is recommended for the follow-up of women who use IUDs as a contraceptive method. However, 3D ultrasonography should be used when malposition is suspected.

  20. Diagnosis of Intra-Abdominal Extralobar Pulmonary Sequestration by means of Ultrasound in a Neonate

    Directory of Open Access Journals (Sweden)

    Claudio Rodrigues Pires

    2013-01-01

    Full Text Available Pulmonary sequestration is a congenital abnormality consisting of a mass of pulmonary tissue that presents an abnormal connection with the tracheobronchial tree, with a blood supply coming from an anomalous artery derived from the systemic circulation. Extralobar pulmonary sequestration is characterized by having pleural coverings that are independent of the normal lungs, with vascular supply usually coming from the aorta or from one of its branches. This diagnosis can be suspected prenatally if an abdominal mass, generally below the diaphragm, is seen. Here, we present a case of a neonate on the second day of life, with ultrasonography showing extralobar pulmonary sequestration located above the left adrenal gland that prenatally simulated a neuroblastoma.

    Intraligamentary pregnancy is an ectopic pregnancy developing within the broad ligament of the uterus. A case of a 20-year-old primigestation primipara woman is reported. The patient at 10 weeks of gestation, presented acute and continuous hypo gastric pain and was referred to ultrasonography examination, showing ectopic pregnancy and oligamnios. Another exam revealed right para-uterine abdominal pregnancy, fetal biometry of 16 weeks, placenta attached to mesosalpinx and severe oligamnios. Considering the fetal prognostics and the proximity of the placenta to iliac blood vessels, artheriographic examination was performed for evaluation of placenta insertion. Surgical procedures as salpingo-oophorectomy at the right side, appendectomy and removal of the fetus were performed.

    A 76-year-old man with a history of multiple laparotomies and severe coronary artery disease was referred to our hospital after the sudden development of pain and numbness in the lower extremities. Computed tomography showed a thrombosed abdominal aortic aneurysm and diffuse aortic atherosclerosis; compatible with a "shaggy aorta." A good response to thrombolytic therapy permitted elective scheduling of abdominal aortic surgery after coronary artery bypass grafting. We operated via an extended left retroperitoneal approach through a thoracoabdominal incision. Epiaortic ultrasonography revealed that only the supraceliac aorta was free of mobile thrombi and had minimal plaque; we therefore placed a proximal aortic cross-clamp there. Anatomic aortic reconstruction was then performed successfully using an aorto-biiliac graft to restore adequate distal blood flow. There were no vital-organ ischemic complications, and the postoperative course was satisfactory.

    The present work deals with the problem of abdominal injuries in polytraumatized patients. The results were obtained from a retrospective study of the records of 530 polytraumatized patients treated at the Central Hospital of the German Federal Armed Forces (Bundeswehr). In all, 193 of these patients had abdominal injuries. The overall mortality was 23.8% (n = 126): mortality among the patients with abdominal injuries was 26% (n = 50). Abdominal injuries alone led to death in 9.1% (n = 1), but mortality increased to 18.4% when at least one extra-abdominal injuries was also present. A combination of abdominal injuries and two or more extra-abdominal lesion led to a mortality rate of 27%. Mortality was found to be age- and sex-related: in young children and patients over 55 years (especially those around 70) mortality was 33.3%-72%. Among the cases with fatal outcome there was a female-to-male ratio of 3:2. The most common causes of death were: hemorrhage shock (62.3%), head injuries (37.7%), septicemia (8.1%), pneumonia, and ARDS (5.4% each). Within the last eight years we have used the following supplementary examination methods: computed tomography, peritoneal lavage, and ultrasonography. The retrospective study has shown that CT is not the examination of choice. The reliability with lavage and ultrasonography was approximately the same, but lavage was found to be more dangerous. Therefore, we abandoned lavage and used sonography only. However, we are of the opinion that any surgeon should use the examination method that has yielded the best results for him or her, to ensure the best possible outcome for the patient.

    Introduction Minor percentage of wooden foreign bodies is radio-opaque. High Resolution Ultrasonography (HRUSG) though existing is sparsely used as a primary imaging modality for diagnosis and localization of retained foreign body. Aim To evaluate the diagnostic accuracy of High Resolution Ultrasonography (HRUSG) in diagnoses and localization of retained foreign body. Materials and Methods A prospective study with registered 46 patients with history of foreign body injury which were initially imaged with conventional radiography was enrolled. Later patients were subjected for high resolution USG of the diseased part with a linear transducer. Surface marking was done for all subjects to assist the surgical exploration. Ultrasound findings were correlated with surgical exploration and histopathological findings. Results Out of 46 patients, forty one showed foreign body with foreign body inflammatory reaction in the form of abscess and/or granulation tissue on high resolution ultrasonography. No foreign body was detected in five patients but they showed focal hypoechogenicity which represented abscess and/or haematoma. On surgical exploration, two out of 41 patients did not reveal foreign body where as rest were found to have foreign body with foreign body inflammatory reaction. Sensitivity and negative predictive value of the current study is 100%. Conclusion High resolution USG is not only an efficient modality in diagnosing and localizing the foreign body in soft tissue, but can also be utilized for guiding the foreign body removal.

    The authors analysed ultrasonography (US) findings in patients with clinical signs of acute appendicitis during a recent 7-months period. The comparative analysis between US findings and surgical-pathologic findings was performed in 193 cases who underwent surgery. There were 52 cases with a sonographically non-visible appendix whose symptoms spontaneously resolved. The inflamed appendix was visualized by high-resolution, real-time US according to the graded-compression method described by Puylaert. The following results noted: 1. Sonographically visualized 136 cases were the target-appearance appendix in 47 cases, the fluid-filled appendix in 66 cases and the irregular marginated mixed echogenic mass-like density with surrounding fluid collection in 23 cases. The appendix was not visualized by US in 109 cases. 2. Appendicitis perforation was predictable in 21 cases of 24 cases. 3. Acute appendicitis was 24 cases (59%) among 41 cases who were sonographically visualized with appendiceal wall thickening less than 3mm and 77 cases (81%) among 95 cases with wall thickening more than 3mm. 4. When the results in women were analyzed separately (n=176), the sensitivity was 86%, the specificity was 76% and the accuracy was 80%. In women, US was helpful for the differential diagnosis between acute appendicitis and other gynecologic disease. 5. In men (n=69), the sensitivity was 88%, the specificity was 67% and the accuracy was 81%. 6. The overall sensitivity was 87%, the specificity was 75% and accuracy was 80% (n=245). Graded-compression US is the examination of choice in the patients with clinical signs of acute appendicitis, particularly in women.

  10. Diagnostic imaging of acute abdominal pain in adults.

    2015-04-01

    Acute abdominal pain is a common presentation in the outpatient setting and can represent conditions ranging from benign to life-threatening. If the patient history, physical examination, and laboratory testing do not identify an underlying cause of pain and if serious pathology remains a clinical concern, diagnostic imaging is indicated. The American College of Radiology has developed clinical guidelines, the Appropriateness Criteria, based on the location of abdominal pain to help physicians choose the most appropriate imaging study. Ultrasonography is the initial imaging test of choice for patients presenting with right upper quadrant pain. Computed tomography (CT) is recommended for evaluating right or left lower quadrant pain. Conventional radiography has limited diagnostic value in the assessment of most patients with abdominal pain. The widespread use of CT raises concerns about patient exposure to ionizing radiation. Strategies to reduce exposure are currently being studied, such as using ultrasonography as an initial study for suspected appendicitis before obtaining CT and using low-dose CT rather than standard-dose CT. Magnetic resonance imaging is another emerging technique for the evaluation of abdominal pain that avoids ionizing radiation.

    Objective: To evaluate abdominal imaging in AIDS. Methods: The imaging examinations (including US, CT and MR) of 6 patients with AIDS associated abdominal foci were analysed retrospectively. All the cases were performed US, and CT scan, of which 4 performed enhanced CT scan and 1 with MR. Results: Abdominal tuberculosis were found in 4 patients, including abdominal lymph nodes tuberculosis (3 cases) and pancreatic tuberculosis (1 case). The imaging of lymph nodes tuberculosis typically showed enlarged peripheral tim enhancement with central low-attenuation on contrast-enhanced CT. Pancreatic tuberculosis demonstrated low-attenuation area in pancreatic head and slightly peripheral enhancement. Disseminated Kaposi's sarcoma was seen in 1 case: CT and MRI scan demonstrated tumour infiltrated along hepatic portal vein and bronchovascular bundles. Pelvic tumor was observed in 1 case: CT scan showed large mass with thick and irregular wall and central low attenuation liquefacient necrotic area in the pelvic cavity. Conclusion: The imaging findings of AIDS with abdominal foci is extraordinarily helpful to the diagnosis of such disease. Tissue biopsy is needed to confirm the diagnosis. (authors)

  12. Intraoperative ultrasonography of the vertebral canal in dogs

    2015-06-01

    Full Text Available Intraoperative ultrasound (IOS can provide details on various conditions of the spinal cord and vertebral canal. The aim of the present study was to evaluate the feasibility of using IOS in dogs undergoing spinal surgery and to describe the main findings. The vertebral canal of 21 dogs was examined with intraoperative ultrasonography: 13 underwent spinal surgery for removal of herniated intervertebral disc material, three for stabilization of vertebral fracture/luxation, two for removal of vertebral neoplasia, and three for cauda equina decompression. Particular attention was given to signs of cord compression. Intraoperative ultrasonography was feasible and useful in dogs undergoing surgery for spinal cord or cauda equina decompression and fracture stabilization. It was not paramount for locating the compression when this had been done via computed tomography (CT, but it showed alterations in spinal cord parenchyma not observed on CT and also confirmed adequate decompression of the spinal cord. The main advantages of intraoperative ultrasonography were estimation of vascularization and extent of spinal cord lesion. Most importantly, it allowed real time evaluation of the spinal cord and vertebral canal, which permits the modification of the surgical procedure.

    Abdominal ultrasonography was performed in six adult captive caracals (Caracal caracal) to describe the normal abdominal ultrasonographic anatomy. Consistently, the splenic parenchyma was hyperechoic to the liver and kidneys. The relative echogenicity of the right kidney's cortex was inconsistent to the liver. The gall bladder was prominent in five animals and surrounded by a clearly visualized thin, smooth, regular echogenic wall. The wall thickness of the duodenum measured significantly greater compared with that of the jejunum and colon. The duodenum had a significantly thicker mucosal layer compared with that of the stomach. Such knowledge of the normal abdominal ultrasonographic anatomy of individual species is important for accurate diagnosis and interpretation of routine health examinations.

    Cholescintigraphy, ultrasonography, and contrast cholangiography were compared in 60 patients. Among those having abdominal pain but no biliary disease or jaundice, cholescintigraphy was normal in 14/14, ultrasound in 10/13, and cholangiography in 13/14. Jaundice due to hepatocellular disease was correctly distinguished from complete biliary obstruction by cholescintigraphy in 17/17 patients and by ultrasound in 14/17. In cholelithiasis, ultrasound was abnormal in 10/12 and cholangiography in 7/9. Cholescintigraphy appeared most sensitive to active cholecystitis; only cholangiography and ultrasound visualized gallstones

    Ultrasonography is the ideal noninvasive imaging modality for evaluation of scrotal abnormalities. It is capable of differentiating the most important etiologies of acute scrotal pain and swelling, including epididymitis and testicular torsion, and is the imaging modality of choice in acute scrotal trauma. In patients presenting with palpable abnormality or scrotal swelling, ultrasonography can detect, locate, and characterize both intratesticular and extratesticular masses and other abnormalities. A 12-17 MHz high frequency linear array transducer provides excellent anatomic detail of the testicles and surrounding structures. In addition, vascular perfusion can be easily assessed using color and spectral Doppler analysis. In most cases of scrotal disease, the combination of clinical history, physical examination, and information obtained with ultrasonography is sufficient for diagnostic decision-making. This review covers the normal scrotal anatomy as well as various testicular and scrotal lesions.

    AIM: To investigate the clinical usefulness of early endoscopic ultrasonography (EUS) in the management of acute biliary pancreatitis (ABP). METHODS: All consecutive patients entering the emergency department between January 2010 and December 2012 due to acute abdominal pain and showing biochemical and/or radiological findings consistent with possible ABP were prospectively enrolled. Patients were classified as having a low, moderate, or high probability of common bile duct (CBD) stones, according to the established risk stratification. Exclusion criteria were: gastrectomy or patient in whom the cause of biliary obstruction was already identified by ultrasonography. All enrolled patients underwent EUS within 48 h of their admission. Endoscopic retrograde cholangiopancreatography was performed immediately after EUS only in those cases with proven CBD stones or sludge. The following parameters were investigated: (1) clinical: age, sex, fever; (2) radiological: dilated CBD; and (3) biochemical: bilirubin, AST, ALT, gGT, ALP, amylase, lipasis, PCR. Association between presence of CBD stone at EUS and the individual predictors were assessed by univariate logistic regression. Predictors significantly associated with CBD stones (P < 0.05) were entered in a multivariate logistic regression model. RESULTS: A total of 181 patients with pancreatitis were admitted to the emergency department between January 2010 and December 2012. After exclusion criteria a total of 71 patients (38 females, 53.5%, mean age 58 ± 20.12 years, range 27-89 years; 33 males, 46.5%, mean age 65 ± 11.86 years, range 41-91 years) were included in the present study. The probability of CBD stones was considered low in 21 cases (29%), moderate in 26 (37%), and high in the remaining 24 (34%). The 71 patients included in the study underwent EUS, which allowed for a complete evaluation of the target sites in all the cases. The procedure was completed in a mean time of 14.7 min (range 9-34 min), without

    Ultrasonography is a valuable tool for the diagnosis of liver disease. Discrete or diffuse lesions can be imaged, aspirated, and biopsied under visual guidance. The ultrasonographic examination of the liver is performed on the right side of the standing animal using a real-time 3.5 to 5.0 MHz linear or convex transducer. This imaging modality also can be used to aspirate bile from the gallbladder for the diagnosis of liver flukes. Ultrasonography cannot be used to evaluate liver regions obscured by the lungs, however.

    The ultrasonography is a very useful diagnostic procedure in obstetric and gynecologic mass. So we analyzed total 153 cases of pelvic ultrasonogram with pathologic diagnoses. The results were as follows: 1. The ages of patients were distributed from 16 to 70 years-old, and the third decade was the most prevalent. 2. Of 153 cases, the ovarian masses were 85 cases, the tubal ones were 49 cases, and the uterine were 19 cases. 3. Of 85 ovarian masses, physiologic ovarian cysts were 44 cases, and cystic teratoma were 14 cases, Of 49 tubal masses, tubal pregnancies were 35 cases and the most prevalent. Of 19 uterine masses, leiomyomas were 11 cases and most prevalent. 4. Of 153 cases, the echo-complex masses were 103 cases, the cystic ones were 34 cases, and the solid ones were 19 cases. 5. The characteristic findings of frequent masses were as follows: (1) The physiologic ovarian cysts were 44 cases, and show mainly cystic or pure cystic masses in 42 cases. (2) The ectopic pregnancy were 36 cases, and show echo-complex masses in 21 cases, and cul-de-sac fluid echo in 22 cases. (3) The cystic teratomas were 14 cases, and reveal mainly cystic or pure cystic masses in 10 cases, and calcification with posterior acoustic shadowing in 6 cases. (4) The uterine leiomyma were 11 cases, and reveal solid mass with abnormal uterine contour in 8 cases. (5) The malignant or borderline malignant lesions were 6 cases. (6) Of 153 cases, the pathologic diagnosis was possible in 98 cases (64.1%).

    To assess the internal echo intensity and morphological variability of masseter muscles on ultrasonography and to establish diagnostic criterion of estimation. Participants consisted of 50 young adults (male 25, female 25) without pathologic conditions and with full natural dentitions. Sonographic examinations were done with real time ultrasound equipment as Logiq 500 (GE Medical Systems, Seoul, Korea) at 3 parts according to lines paralleling with ala-tragus line as reference line. The thickness and area of masseter muscles according to reference line in cross-sectional images were measured at rest and at maximum contraction. The visibility and width of the internal echogenic intensity of the masseter muscles were also assessed and the muscle appearance was classified into 4 types. Data were statistically analyzed by paired t-test and x2-test. 1. When comparing the thickness and area of masseter muscles concerning with gender, there was few significant difference between right and left sides, however, there were significant differences between males and females except for the greatest thickness of left side. 2. The changes of the greatest thickness and the area between rest and maximum contraction showed that the part of the least thickness manifested more increase at maximum contraction. 3. Each part the manifestations of the internal echogenic intensity of the masseter muscles were different depending on the locations. But there was no statistically significance. Changes of muscles thickness with contraction and internal echogenic intensity with locations showed great disparity within the masseter muscles, which will be diagnostic criteria for pathophysiologic and anatomic changes of masseter muscles.

    The concept of autoimmune pancreatitis has recently been established, and ultrasonographic findings we obtained from five cases consistent with autoimmune pancreatitis are reported here. Case 1, a 77-year-old man, was admitted complaining of loss of body weight. Serum hepatobiliary enzymes and γ-globulin levels were elevated, and antinuclear antibody was positive, Abdominal ultrasonography showed dilatation of the intrahepatic bile duct, wall thickening of the common bile duct and hypoechoic swelling of the pancreatic head and body. ERCP revealed multiple stenosis of the intra-and extra-hepatic bile ducts, and diffuse irregular narrowing of the main pancreatic duct. The patient complained of thirst, and the minor salivary gland was examined histologically. Our diagnosis was Sjögren syndrome accompanied by sclerosing cholangitis and a pancreatic lesion. Obstructive jaundice also developed, and PTCD was therefore performed. Both the pancreatic swelling and multiple stenosis of the bile duct improved after steroids were administered. Case 2, a 71-year-old man, was admitted with jaundice. Abdominal ultrasonography showed hypoechoic swelling of the pancreas. ERCP showed stenosis of the common bile duct in the pancreatic head region and diffuse irregular narrowing of the main pancreatic duct. Histological examination of the minor salivary gland suggested Sjögren syndrome. Steroids were therefore administered because the presence of both hyper-γ-globulinemia and positive antinuclear antibody suggested involvement of the autoimmune mechanism. Steroid therapy improved the jaundice as well as the findings from the cholangiograms and pancreatograms. We also encountered three similar cases, all consistent with the concept of autoimmune pancreatitis. The ultrasonographic findings of the pancreatic lesion (1) showed them as homogeneous and markedly hypoechoic areas and, (2) visualized the main pancreatic duct in the lesion, which facilitated a differential diagnosis of the

    To describe the abdominal imaging findings of patients with gastrointestinal Basidiobolus ranarum infection. A literature search was performed to compile the abdominal imaging findings of all reported worldwide cases of gastrointestinal basidiobolomycosis (GIB). In addition, a retrospective review at our institution was performed to identify GIB cases that had imaging findings. A radiologist aware of the diagnosis reviewed the imaging findings in detail. Additional information was obtained from the medical records. A total of 73 GIB cases have been published in the medical literature. The most common abdominal imaging findings were masses in the colon, the liver, or multiple sites and bowel wall thickening. Initially, many patients were considered to have either a neoplasm or Crohn disease. We identified 7 proven cases of GIB at our institution, of which 4 had imaging studies (4 computed tomography [CT] examinations, 4 abdominal radiographs, and an upper gastrointestinal study). Imaging studies showed abnormalities in all 4 cases. Three-fourths of our study patients had an abdominal mass at CT. Two of 3 masses involved the kidneys and included urinary obstruction. All masses showed an inflammatory component with adjacent soft tissue stranding, with or without abscess formation. Radiologists should consider GIB when a patient from an arid climate presents with abdominal pain, weight loss, and an inflammatory abdominal mass on CT. Abdominal masses of the colon or liver, bowel wall thickening, and abscesses are the most common imaging findings.

    BACKGROUND: Acute hepatobiliary pathology is a common general surgical emergency referral. Diagnosis requires imaging of the biliary tree by ultrasonography. The accuracy and impact of surgeon-performed ultrasonography (SUS) on the diagnosis of emergent hepatobiliary pathology was examined. METHODS: A prospective study, over a 6-month period, enrolled all patients with symptoms or signs of acute hepatobiliary pathology. Patients provided informed consent and underwent both SUS and standard radiology-performed ultrasonography (RUS). SUS was performed using a 2-5-MHz broadband portable ultrasound probe by two surgeons trained in ultrasonography, and RUS using a 2-5-MHz fixed unit. SUS results were correlated with those of RUS and pathological diagnoses. RESULTS: Fifty-three consecutive patients underwent 106 ultrasonographic investigations. SUS agreed with RUS in 50 (94.3 per cent) of 53 patients. SUS accurately detected cholelithiasis in all but two cases and no patient was inaccurately diagnosed as having cholelithiasis at SUS (95.2 per cent sensitivity and 100 per cent specificity). As an overall complementary diagnostic tool SUS provided the correct diagnosis in 96.2 per cent of patients. Time to scan was significantly shorter following SUS (3.1 versus 12.0 h, P < 0.05). CONCLUSION: SUS provides a rapid and accurate diagnosis of emergency hepatobiliary pathology and may contribute to the emergency management of hepatobiliary disease.

    The aim of the study was to evaluate the assessability of the suprascapular nerve (SSN) by ultrasonography in cadavers and healthy volunteers. With ultrasonography guidance, needles were placed at origin of the SSN of four cadavers and evaluated by dissection. Two blinded radiologists performed 60 ultrasonography scans in 30 healthy volunteers to study the entire SSN at five anatomical landmarks. Dissection revealed that the needles were correctly located at the nerve's origin. There were no significant differences between the two radiologists' measurements of nerve size and depth. The interobserver correlation for the description of the nerve at the five predefined anatomical landmarks was very good (ICC=0.7-1). Five anatomical landmarks were used to analyze the SSN with ultrasonography. Its supraclavicular portion was easier to describe than its scapular portion; a segment of the SSN was not visible between these two portions. Copyright © 2017 Editions françaises de radiologie.

    Post traumatic anterior abdominal wall hernia can be ignored in emergency settings. We here report the case of a 32-year-old patient with a BMI of 30 kg/m 2 , suffering from anterior abdominal wall hernia as a result of a road accident. This lesion wasn't detected during clinical examination. Abdominal tomodensitometry showed a defect of 8 cm in the anterior abdominal wall. The patient underwent surgery during which a musculoaponeurotic defect of 12 cm was detected. The repair was carried out using interrupted suture. The postoperative course was marked by a secondarily infected skin necrosis. The evolution was satisfactory after directed cicatrization. At 3 months postoperatively the patient was doing well with a healed wound and a strong abdominal wall.

    Plain film of the abdomen is widely used in the diagnostic evaluation of intestinal occlusion. Even though this technique can yield a panoramic and high-resolution view of gas-filled intestinal loops, several factors, such as type and duration of occlusion, neurovascular status of the intestine and general patient condition, may reduce the diagnostic specificy of the plain film relative to the organic or functional nature of the occlusion. From 1987 to 1989, fifty-four patients with intestinal occlusion were studied combining plain abdominal film with abdominal ultrasound (US). This was done in order to evaluate whether the additional information obtained from US could be of value in better determining the nature of the ileus. US evaluation was guided by the information already obtained from plain film which better demonstrates gas-filled loops. The results show that in all 27 cases of dynamic ileus (intestinal ischemia, acute appendicitis, acute cholecistis, acute pancreatitis or blunt abdominal trauma) US demonstrates: intestinal loops slightly increased in caliber, with liquid content, or loops containing rare hyperechoic particles, intestinal wall thickening and no peristalsis. In 27 cases of acute, chronic or complicated mechanical ileus (adhesions, internal hernia, intestinal neoplasm, peritoneal seedings) US shows: 1) in acute occlusion: hyperperistaltic intestinal loops containing inhomogeneous liquid; 2) in chronic occlusion: liquid content with a solid echigenic component; 3) in complicated occlusion: liquid stasis, frequent increase in wall thickness, moderate peritoneal effusion and inefficient peristalsis. In conclusion, based on the obtained data, the authors feel that the combination of plain abdominal film and abdominal US can be useful in the work-up of patient with intestinal occlusion. The information provided by US allows a better definition of the nature of the ileus

    Full Text Available Background: Ultrasonography is increasingly used for teaching physical examination in medical schools. This study seeks the opinions of educators as to which physical examinations would be most enhanced by the addition of ultrasonography. We also asked when ultrasound-aided physical examination teaching could have deleterious effects if used outside its intended scope. Methods: All of the educators from the University of Calgary Master Teacher Program were invited to complete a 22-item paper-based survey. Survey items were generated independently by two investigators, with input from an expert panel (N = 5. Results: Of the 36 educators, 27 (75% completed the survey. Examinations identified to be potentially most useful included: measuring the size of the abdominal aorta, identifying the presence/absence of ascites, identifying the presence/absence of pleural effusions, and measuring the size of the bladder. Examinations thought to be potentially most harmful included: identifying the presence/absence of intrauterine pregnancy, measuring the size of the abdominal aorta, and identifying the presence/absence of pericardial effusion. Conclusions: Examinations that are potentially the most useful may also be potentially the most harmful. When initiating an ultrasound curriculum for physical examinations, educators should weigh the risks and benefits of examinations chosen.

    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy.

    Focal nodular hyperplasia (FNH) is an asymptomatic benign liver tumor that may be detected accidentally during an abdominal ultrasound examination; it is associated with unspecific complaints, sometimes painful. Diagnosis can be precise using imaging techniques like ultrasonography. The diagnostic criteria are represented by the spatial display of the tumoral vessels and their hemodynamic characteristics. Sometimes differential diagnostic issues occur with other benign or malignant liver tumors. We present the case of a young female patient without a personal pathological history, who complained of intense, diffuse, intermittent, non-systematic abdominal pain and who underwent ultrasound examination, followed by contrast-enhanced ultrasound. With this technique, we evidenced a solid extrahepatic tumor, which was mobile at the patient's change of position and had the hemodynamic features of FNH. The article also tackles the problem of intra-abdominal pedunculated tumors.

    To correlate the grades on power Doppler ultrasonography with clinical disease activity indices and acute phase reactant values for assessing the activity of synovitis in patients with rheumatoid arthritis. Twenty patients with rheumatoid arthritis diagnosed on the basis of American College of power Doppler ultrasonography. Two experienced radiologists evaluated, in consensus, the power Doppler signals as follows: grade I=no flow or minimal flow, grade 2=mild flow, grade 3=moderate flow and grade 4= marked flow. The clinical disease activity indices consisted of the counts of tender joints and swollen joints, patient's assessment of pain, patient's global assessment of disease activity, physician's globe assessment of disease activity and patient's assessment of physical function. Acute-phase reactants included CRP and ESR. The grades on power Doppler ultrasonography were correlated with clinical disease activity indices as well as acute-phases reactant values by a use of Spearman rank correlation coefficient. The grades on power Doppler ultrasonography showed a statistically significant correlation with tender joint count (rs=.835; p<.05), swollen joint count (rs=.833; p<.05), physician's global assessment of disease activity (rs=.857; p<.05), CRP (rs=.838; P<.05) and ESR (rs=.838; p<.05). The power Doppler ultrasonography is an useful diagnostic modality for assessing the activity of synovitis in patients with rheumatoid arthritis.

    Objective: To evaluate the uterine cervix length with magnetic resonance imaging in comparison with findings at trans vaginal ultrasonography. Materials and methods: Twenty pregnant women between the 19th and 30th gestational weeks underwent magnetic resonance imaging and trans vaginal ultrasonography for evaluation of their uterine cervix. Measurements by means of magnetic resonance imaging were performed by two specialists in imaging diagnosis for calculating the interobserver variability of the method. Results: Calculation of the Pearson's correlation coefficient between measurements of the cervical length demonstrated a significant correlation between the results of both methods (r=0.628; p<0.01). The paired t test demonstrated no statistically significant difference between measurements obtained by trans vaginal ultrasonography and magnetic resonance imaging (p=0.068). Interobserver agreement in cervical measurements by magnetic resonance imaging was high (α=0.96), demonstrating the reliability of the method. Conclusion: The comparison between both imaging methods in the evaluation of cervical biometry showed no statistically significant difference thus reinforcing the utilization of ultrasonography. However, in some cases where trans vaginal ultrasonography is contraindicated, magnetic resonance imaging can be alternatively utilized for measurement of the cervical length. (author)

    Objective: The aim of this study is to evaluate the efficacy of contrast-enhanced ultrasonography for the diagnosis of pancreatic tumors. Materials and methods: Contrast-enhanced ultrasonography with Levovist was performed on 62 consecutive patients (53 with pancreatic cancer, 4 with islet cell tumor, 3 with inflammatory pancreatic tumor, and 2 with metastatic tumor). The vascular and perfusion image phases of the tumors were evaluated and compared with the findings of contrast-enhanced computed tomography. Results: Contrast-enhanced ultrasonography showed tumor vessels around and/or in the tumor at the vascular image phase in 79% of pancreatic cancer patients (42/53). At the perfusion image phase, 96% of pancreatic cancers (51/53) were classified as hypo-enhancement type. However, tiny spotty or irregular heterogeneous enhanced lesions were found in 84% of hypo-enhanced pancreatic cancer patients (43/51). The presence of small vessels at the vascular image phase was closely correlated with the presence of these intratumor regional enhanced lesions at the perfusion image phase (κ coefficient = 0.42). The sensitivity of contrast-enhanced ultrasonography (100%) for pancreatic cancer was superior to that of contrast-enhanced computed tomography (91%), but no significant difference was observed between the two (McNemar test: p = 0.063). Conclusion: Contrast-enhanced ultrasonography with Levovist successfully visualizes fine vessels and enhancement in pancreatic tumors, and is useful for evaluating pancreatic tumors

    Renal artery duplex ultrasonography (RA-DUS) is commonly used for the evaluation and follow-up of renal artery atherosclerotic disease. In a complete study, renal artery flow is evaluated from the vessel origin to the intraparenchymal branches. The quality of RA-DUS is in part technologist-dependent, but many factors may affect the ability to complete a diagnostic examination. This study evaluated the clinical and technical factors that predict the ability to obtain a complete RA-DUS examination. A prospective evaluation of all patients undergoing RA-DUS between July 2008 and February 2009 was performed. Factors such as patient age, gender, body mass index, technologists' years of experience, patient care setting (inpatient vs. outpatient), bedside examination, smoking before the examination, fasting status, and recent abdominal surgery were all recorded. Multivariate logistic regression analysis was performed. A p value of ≤ 0.05 was considered significant. During the study period, 250 patients underwent RA-DUS (mean age: 59.9 ± 17.8 years, 57% [143] female). A total of 87 (35%) examinations were incomplete. This included nondiagnostic examinations which did not exhibit any segment of the renal artery. Factors that were associated with an incomplete examination included technologists' years of experience (OR = 0.92, p = 0.042), bedside examination (OR = 4.17, p = 0.016), and recent abdominal surgery (OR = 3.45, p = 0.047). Body mass index, fasting status, and smoking before the examination did not affect the ability to obtain a complete study. One-third of the RA-DUS studies were classified as incomplete by the strict criteria used in this prospective study. An experienced ultrasound technologist is more likely to obtain a complete RA-DUS examination. Recent abdominal surgery and bedside examinations were predictive of a limited examination as well. Vascular laboratories should consider these factors when scheduling examinations so as to obtain complete RA

    This article presents and description of the ultrasonographic and computed tomographic findings with a discussion on the imaging features in three patients with epigastric hernias, simulating abdominal wall lipomas. Ultrasonogram showed a heterogeneous hypoechoic mass encircled by echogenic rim within subcutaneous space of the abdominal wall. Computed tomographic findings were a localized fatty mass surrounded by a thin capsule in association with a focal discontinuity of the linea alba. Ultrasonogram was not diagnostic, but computed tomogram was suggestive because of the well demonstrated focal defect in linea alba.

    The purposes of this study were (1) to establish the intrarater sliding and change in thickness of the transversus abdominis (TrA) measurement at the posterior muscle-fascia junction and (2) to examine the relationship between the muscle thickness and sliding of the TrA at the anterior and posterior sites. Asymptomatic participants (n = 20) were placed into the hook-lying position to perform the abdominal drawing-in maneuver viewed in B-mode with a 5- to 12-MHz linear ultrasound transducer. The outcome variables included the resting thickness, the thickness during contraction, the change of thickness, and the change of sliding length. Both intraclass correlation coefficient and Pearson correlation were used for analysis. Measuring the thickness and sliding of the TrA at the posterior muscle-fascia junction showed good reliability (intraclass correlation coefficient (3,3), 0.89-0.98). The correlations between the sliding measurements of the TrA at the anterior and posterior sites were moderate to good (r = 0.41-0.74). This study found that measuring the musculofascial corset from the posterior site using ultrasonography is reliable, allowing for ultrasound measurements at both the anterior and posterior sites of the TrA to provide a comprehensive evaluation of the TrA fascia.

    Full Text Available Aim: To determine whether duplex ultrasonography (DU without verification with diagnostic angiography (DA is a sufficient visual- ization technique for pre-operative examination of patients with CLI (critical limb ischemia indication for percutaneous transluminal balloon angioplasty (PTBA.Materials and Methods: We examined 254 patients (290 limbs in total with diabetes mellitus (DM and CLI. All participants were subdivided into two groups: “A” (PTBA with pre-operative DU+DA and “B” (PTBA with pre-operative DU. We evaluated data coherence between DU and DA (pre- or intraoperative methods, as well as DU diagnostic specificity and sensitivity in determining degree and localization of vascular lesions. We also investigated specific clinical factors compromising DU diagnostic capabilities in patients with DM.Results: Our data suggests adequate coherence between DU and DA for pre-operative visualization. Group “B” showed significantly higher diagnostic sensitivity and specificity for visualization of the lower third of superficial femoral artery and tibial arteries despite abdominal obesity, grossly evident calcification and peripheral edema.Conclusion: Duplex ultrasound is efficient and precise enough to determine optimal management tactics in most patients with DMand CLI without resort to invasive methods.

    specificities were 66.7% in ultrasonography, 66.7% in magnetic resonance imaging, and 40% in ductoscopy. Intraductal papillomas were mostly observed as oval nodules with well-circumscribed smooth margins within dilated ducts and persistant in the dynamic analysis. Lesions that protruded into the lumen of the ducts, either solitary or multiple, were characteristic ductoscopy findings of our patients who were diagnosed as having papilloma/papillomatosis. Magnetic resonance imaging and ductoscopy had no statistical superiority over each other, however they were superior to ultrasonography in the diagnosis of pathologic nipple discharge. Magnetic resonance imaging may be highly sensitive for diagnosing nipple discharge with new techniques and sequences and a non-invasive method that more advantageous for showing ductal tree visualization and is able to detect completely obstructed intraductal lesions.

To this 39 intended for commercial slaughter horses were evaluated. Sonographic evaluation before slaughter transabdominal via the left side of abdomen for evaluation of the stomach was performed. After the slaughter of these animals their stomachs were collected, evaluated and photographed. The study concluded that ultrasonography identified the stomach in all animals evaluated, but did not allow a careful evaluation of the entire length of the viscera, especially the aglandular region and pleated border. All animals evaluated had injury to the gastric mucosa in different degrees. In animals evaluated, the stomach region was most affected by injuries glandular region, although the most severe lesions have been found in the ruffled border adjacent to aglandular region.

    Necrotizing fasciitis is a critical illness involving skin and soft tissues, which may develop after blunt abdominal trauma causing abdominal wall hernia and representing a great challenge for physicians. A 52-year-old man was brought to the emergency department after a road accident, presenting blunt abdominal trauma with a large non-reducible mass in the lower-right abdomen. A first, CT showed abdominal hernia without signs of complication. Three hours after ICU admission, he developed hemodynamic instability. Therefore, a new CT scan was requested, showing signs of hernia complication. He was moved to the operating room where a complete transversal section of an ileal loop was identified. Five hours after surgery, he presented a new episode of hemodynamic instability with signs of skin and soft tissue infection. Due to the high clinical suspicion of necrotizing fasciitis development, wide debridement was performed. Following traumatic abdominal wall hernia (TAWH), patients can present unsuspected injuries in abdominal organs. Helical CT can be falsely negative in the early moments, leading to misdiagnosis. Necrotizing fasciitis is a potentially fatal infection and, consequently, resuscitation measures, wide-spectrum antibiotics, and early surgical debridement are required. This type of fasciitis can develop after blunt abdominal trauma following wall hernia without skin disruption.

    The intent of this review is to discuss and comment on common clinical scenarios in which contrast-enhanced ultrasonography (CEUS) may play a decisive role and to illustrate important points with typical cases. With the advent of CEUS, the scope of indications for ultrasonography has been dramati...... thirds of the global population may receive no such care. Ultrasound imaging with CEUS has the potential to correct this inequity....... dramatically extended, and now includes functional imaging and tissue characterization, which in many cases enable tumor diagnosis without a biopsy. It is virtually impossible to imagine the practice of modern medicine as we know it in high-income countries without the use of imaging, and yet, an estimated two...

  11. Focused Real-Time Ultrasonography for Nephrologists

    Directory of Open Access Journals (Sweden)

    Matthew J. Kaptein

    2017-01-01

    Full Text Available We propose that renal consults are enhanced by incorporating a nephrology-focused ultrasound protocol including ultrasound evaluation of cardiac contractility, the presence or absence of pericardial effusion, inferior vena cava size and collapsibility to guide volume management, bladder volume to assess for obstruction or retention, and kidney size and structure to potentially gauge chronicity of renal disease or identify other structural abnormalities. The benefits of immediate and ongoing assessment of cardiac function and intravascular volume status (prerenal, possible urinary obstruction or retention (postrenal, and potential etiologies of acute kidney injury or chronic kidney disease far outweigh the limitations of bedside ultrasonography performed by nephrologists. The alternative is reliance on formal ultrasonography, which creates a disconnect between those who order, perform, and interpret studies, creates delays between when clinical questions are asked and answered, and may increase expense. Ultrasound-enhanced physical examination provides immediate information about our patients, which frequently alters our assessments and management plans.

    2016-01-01

    Objective The purpose of this study is to present diagnostic ultrasonography assessment of an occult fracture in a case of persistent lateral ankle pain. Clinical Features A 35-year-old woman presented to a chiropractic clinic with bruising, swelling, and pain along the distal fibula 3 days following an inversion ankle trauma. Prior radiographic examination at an urgent care facility was negative for fracture. Conservative care over the next week noted improvement in objective findings, but the pain persisted. Intervention and Outcome Diagnostic ultrasonography was ordered to assess her persistent ankle pain and showed a minimally displaced fracture of the fibula 4 cm proximal to the lateral malleolus. The patient was referred to her primary care physician and successfully managed with conservative care. Conclusion In this case, diagnostic ultrasonography was able to identify a Danis-Weber subtype B1 fracture that was missed by plain film radiography. PMID:27069430

    Abstract Mediastinal masses are usually assessed by computer tomography (CT) and magnetic resonance imaging (MRI). Transthoracic ultrasonography (TUS) can also provide useful information concerning prevascular and posterior mediastinal masses abutting the thoracic wall, but is underused for mediastinal pathology. Moreover, it provides a valuable and safe method for guiding interventional procedures in those areas, even in cases when other approaches are difficult or impossible. Considering TU...

    Ultrasonography is a predominantly accurate, relatively simple unique diagnostic method of obstructive jaundice. The ultrasonographic findings of obstructive jaundice are dilated intra- and extrahepatic duct with intraluminal hyper reflective echo or mass in and/ or around the bile duct. The superiority of high resolution real time ultrasonography for the diagnosis of obstructive jaundice is bases on the easy detectability of extra- and intrahepatic bile ducts by its multiple sectional images in a short time, the flexibility of probe and small crystal size. Author evaluated real time sonographic findings 46 obstructive jaundice patients confirmed by surgery or radiographical examinations. The results were: 1. Diameter of extrahepatic duct in obstructive jaundice were varied from normal to 4.0 Cm, mostly 8 to 10 mm in diameter (26%). Degree of dilatation of biliary duct appeared more prominent in cancer patients than other causes of obstruction. 2. The site of obstruction was detected in 85% (39/46) and its common site was common bile duct in 63% (29/46). 3. The diagnostic accuracy of choledocholithiasis and cancer was 82% (22/27) and 44% (4/9), respectively. Diagnostic accuracy of the real time ultrasonography in obstructive jaundice was over all 75% (34/46)

    Full Text Available AIM The aim of the study was to evaluate efficacy, sensitivity, specificity of ultrasonography, conventional angiography, CT Angiography in mesenteric ischaemia. MATERIALS AND METHODS Prospective study was performed. 35 patients with clinically suspected mesenteric ischaemia were included in the study. The study was conducted from month of November 2013 to August 2015. The patients age ranged from 35 to 70 years (Mean age was 57±11.2 years. All cases met the criteria of acute nontraumatic or chronic abdominal pain and suspected mesenteric vascular ischaemia. All 35 cases were evaluated in surgery department, then underwent USG, conventional angiography, CTA. Out of 20 patients, 2 patients were inconclusive and 4 patients had other findings of abdominal pain. USG and CT angiographic findings were correlated with surgical findings in acute mesenteric ischaemia (AMI cases & conventional angiography in chronic mesenteric ischaemia (CMI cases. RESULT Ultrasonography has lower sensitivity and high specificity. Conventional angiography has moderate sensitivity and high specificity. CT angiography is highly sensitive and specific in detecting mesenteric ischaemia. CONCLUSION Conventional angiography is considered as the gold standard test for patients with acute and chronic mesenteric ischaemia except for hemodynamically unstable patients with acute mesenteric ischaemia. CTA is an emerging diagnostic test with high sensitivity and specificity in the setting of both acute and chronic mesenteric ischaemia and should be considered the first-line imaging test. CT can also accurately assess for other causes of acute and chronic abdominal pain, and it provides excellent anatomic mapping of the mesenteric vasculature, which is essential in the preoperative planning. US of the abdomen with Doppler waveform analysis can depict proximal mesenteric thrombosis and secondary signs of bowel compromise, but it is limited in the diagnosis of distal occlusions

    Hereditary angioedema is an episodic swelling disorder with autosomal dominant inheritance characterized by sudden attacks of peripheral swelling. Patients also commonly have episodic swelling of the wall of hollow viscera, including the bowel. We present a 33-year-old previously healthy male with a complaint of acute-onset intense abdominal pain localized in the epigastrium. Pain irradiated to the right lower quadrant and was associated with five episodes of vomiting. Computed tomography showed thickening of the duodenal wall with liquid in the subphrenic space. Complementary laboratory tests showed low C4 complement levels (5.5 mg/dl) and 30% complement C1 inhibitor activity. Hereditary angioedema is caused by a deficiency (type I) or dysfunction (type II) in complement C1 inhibitor. Abdominal associated with angioedema may manifest as severe acute-onset abdominal pain or as moderately severe chronic recurrent abdominal pain. Two medications are currently FDA-approved for the treatment of these patients.

    We evaluated the usefulness of endoscopic ultrasonography (EUS) in diagnosing common bile duct (CBD) stones in comparison with computed tomography (CT) and conventional ultrasonography (US). Two hundred eighteen cases with a clear cholangiogram on endoscopic retrograde cholangiopancreatography (ERCP) were included in this study. In 81 patients, CBD stones were confirmed. Choledocholithiasis cases in CT, US and EUS were 62/183, 68/190 and 24/119 respectively. The average maximum diameter of stones in EUS (7.96±17.4 mm) was statistically smaller than CT (11.6±44.0 mm) and US (12.0±52.2 mm). The sensitivity and accuracy of EUS were 95.8% and 97.5% respectively, and statistically higher than CT (72.6%, 90.2%) and US (35.3%, 75.3%). Especially in cases with stones smaller than 10 mm, the sensitivity of EUS (95.0%) was higher than CT (53.1%) and US (18.4%). Different from CT and US, the sensitivity of EUS was independent on the character of CBD (dilated or not dilated). In conclusion, EUS showed almost the same sensitivity as ERCP. Because the sensitivity of EUS is independent of the size of stones and of the characteristics of CBD, EUS is especially useful in suspected choledocholithiasis cases with stones smaller than 10 mm and without dilatation of CBD.

    Because of the many therapeutic options available, a reliable staging is crucial for rectal neoplasia management. Adenomas and cancers limited to the submucosa without lymph node involvement may be treated locally. The aim of this study is to evaluate the diagnostic accuracy of endorectal ultrasonography in the staging of neoplasias suitable for local treatment. We considered all patients who underwent endorectal ultrasonography between 2001 and 2010. The study population consisted of 92 patients with 92 neoplasias (68 adenocarcinomas and 24 adenomas). A 5 and 7.5MHz linear array echoendoscope was used. The postoperative histopathologic result was compared with the preoperative staging defined by endorectal ultrasonography. Adenomas and cancers limited to the submucosa were considered together (pT0-1). The sensitivity, specificity, overall accuracy rate, positive predictive value, and negative predictive value of endorectal ultrasonography for pT0-1 were 86%, 95.6%, 91.3%, 94.9% and 88.7%. Those for nodal involvement were 45.4%, 95.5%, 83%, 76.9% and 84%, with 3 false positive results and 12 false negative. For combined pT0-1 and pN0, endorectal ultrasonography showed an 87.5% sensitivity, 95.9% specificity, 92% overall accuracy rate, 94.9% positive predictive value and 90.2% negative predictive value. Endorectal linear array ultrasonography is a reliable tool to detect rectal neoplasias suitable for local treatment. Copyright © 2011 Editrice Gastroenterologica Italiana S.r.l.

    Many chronic renal diseases lead to the final common state of decrease in renal size, parenchymal atrophy, sclerosis and fibrosis. The ultrasound image show a smaller kidney, thinning of the parenchyma and its hyperechogenicity (reflecting sclerosis and fibrosis). The frequency of renal cysts increases with the progression of the disease. Ultrasound generally does not allow for the exact diagnosis of an underlying chronic disease (renal biopsy is usually required), but it can help to determine an irreversible disease, assess prognosis and avoid unnecessary diagnostic or therapeutic procedures. The main exception in which the ultrasound image does not show a smaller kidney with parenchymal atrophy is diabetic nephropathy, the leading cause of chronic and end-stage renal failure in developed countries in recent years. In this case, both renal size and parenchymal thickness are preserved until end-stage renal failure. Doppler study of intrarenal vessels can provide additional information about microvascular and parenchymal lesions, which is helpful in deciding for or against therapeutic intervention and timely planning for optimal renal replacement therapy option.

    Congenital abdominal wall defects that are located outside of the anterior wall are extremely rare and difficult to classify because there are no well accepted guidelines. There are two regions outside of the anterior wall: the flank or lateral wall; and the lumbar region. We report the case of a patient with an oval 3 cm-diameter hernia defect located above the anterior axillary line, which affects all layers of the muscular wall. An anorectal malformation consisting of a recto-vestibular fistula was also identified, and chest X-ray showed dextrocardia. The suggested treatment is repair of the defect before 1 year of age. Given that the anomalies described may accompany lateral abdominal wall hernia, it is important to diagnose and treat the associated defects. © 2016 Japan Pediatric Society.

    To derive norms for the size of uterus, uterine shape (fundal-cervical ratio) and ovarian volume in girls in various Tanners stages of puberty. Pelvic ultrasound was performed in ninety-two healthy girls in the age group of 8-15 years. These included twenty girls each in Tanner stages 1-4 and twelve in stage 5. All the subjects enrolled in the study had a weight and height within 5th-95th percentile of NCHS standards and their bone ages corresponded to the chronological age. Uterine height, fundal-cervical ratio (FCR) and ovarian volume were measured in all the subjects. The data was stratified according to various pubertal stages as well as for different ages. Statistical analysis was carried out to derive the percentiles for the three parameters in different pubertal stages and to study the correlation between these parameters and age, weight and height of the subjects. A statistically significant increase in uterine height, FCR and ovarian volume was observed with progressive pubertal stages. Maximum increase in uterine height was observed during the transition from stage 2 to stage 3. All girls beyond the age of 10 years or beyond Tanner stage 2 had a FCR>1. The ovarian volume, after showing an initial increase, tended to plateau and there was no significant increase from stage 4-stage 5. A significant correlation was found between the three parameters and the subject's age, weight and height, the maximum correlation was with age (correlation coefficients being 0.748, 0.648, 0.568 for uterine height, FCR and ovarian volume respectively). Centiles for these parameters were obtained for different pubertal stages. This work has provided some guidelines for normative data for various pubertal stages as well as for ages between 8-15 years.

    Pregnancies in graft recipients are associated with increased risk of a number of pathologies. The aim of the study was to analyze results of brain and abdominal ultrasonography and echocardiography (ECHO) in neonates born to liver (LTx) or renal recipients (RTx). The study group consisted of 82 neonates born to transplanted women (46 neonates of liver recipients and 36 neonates of renal recipients), enrolled in a retrospective study. The control group consisted of 74 neonates from the general population. Sonographic examination of the brain was performed to check for the presence of intra-/periventricular hemorrhage (IVH/PVH) according to Papile, and periventricular leukomalacia (PVL).The results of abdominal ultrasonography and 2-dimensional echocardiography (ECHO) were compared between the groups. The immunosuppressive therapy used during pregnancy was also analyzed. No significant differences were observed between the frequency of IVH in LTx and RTx groups and LTx, RTx, and control groups. Abdominal ultrasonography revealed 1 case of suprarenal hemorrhage, 1 case of cystic kidney, and 3 cases of pyelocalyceal system dilatation in the study group. There were no abnormalities in the echocardiography in 97.8% of children born to mothers after LTx and in 94.4% after RTx. There were significant differences in the immunosuppressive therapy between the pregnant women after LTx and RTx. The risk was not increased in intra-/periventricular hemorrhage and congenital abnormalities of the gastrointestinal tract and heart in neonates of mothers after organ transplantation, regardless of the immunotherapy used, and risk was similar to that of the general population.

    Acute appendicitis is one of the most common causes of acute abdominal pain prompting emergency department (ED) visits. It is critical for the physicians to promptly and accurately diagnose acute appendicitis. The present study aimed to evaluate the diagnostic efficacy of Doppler ultrasonography (USG) in patients with acute appendicitis and compare this new method with other commonly used radio-diagnostic tools. All patients who were diagnosed with acute appendicitis at the Kecioren Training and Research Hospital ED and later underwent appendectomy between October 2012 and April 2013 were included in the study. Approval from the ethics committee was obtained for this prospective study. The patients' demographic information, physical examination findings, vital signs, Alvarado scores, and laboratory and radiological exam results were recorded. A total of 60 patients were enrolled in the study. In 46 of the 60 patients, diagnosis of acute appendicitis was confirmed by histopathology results, whereas 14 patients, diagnoses was not confirmed by lab tests. Doppler USG could detect 43 of the 46 patients as true positives, and it detected 2 of the 14 patients with negative lab results as false positives. For diagnosis of acute appendicitis, sensitivity of appendicular Doppler USG was 93%, specificity was 85%, accuracy was 91%, positive likelihood ratio was 6.5, and negative likelihood ratio was 0.08. Doppler imaging can offer a high level of diagnostic success in patients with acute appendicitis. Appendicular Doppler USG offers a rapid and easy application without the need to expose patients to contrast medium and is superior to both USG and computed tomography. Therefore, we recommend the use of appendicular Doppler imaging as the primary radiological exam in diagnosing acute appendicitis.

    Abstract Mediastinal masses are usually assessed by computer tomography (CT) and magnetic resonance imaging (MRI). Transthoracic ultrasonography (TUS) can also provide useful information concerning prevascular and posterior mediastinal masses abutting the thoracic wall, but is underused for mediastinal pathology. Moreover, it provides a valuable and safe method for guiding interventional procedures in those areas, even in cases when other approaches are difficult or impossible. Considering TUS a very useful imagistic method for diagnosing mediastinal masses, we present a pictorial essay of various mediastinal diseases which can be assessed by this method. PMID:29245326

    If morbidity and mortality are to be reduced in patients with penetrating abdominal trauma, first priority goes to prompt and accurate determination of peritoneal penetration and identification of the need for surgery. In this setting, laparoscopy may have an important impact on the rate of negative or non-therapeutic laparotomies. We analyzed indications and patient selection criteria for laparoscopy in penetrating trauma along with outcomes. The analysis focused on identification of peritoneal penetration and injuries to the diaphragm, small intestine, and mesentery. Results from the early phase of laparoscopy were compared with those from recent decades with more advanced laparoscopic equipment and instruments and more experienced surgeons. A systematic review of the role of laparoscopy in penetrating abdominal trauma shows a sensitivity ranging from 66.7 to 100%, specificity from 33.3 to 100% and accuracy from 50 to 100%. Publications from the 1990s found trauma laparoscopy to be inadequate for detecting intestinal injuries and so to lead to missed injuries. Twenty-three of the 50 studies including the most recent ones report sensitivity, specificity, and accuracy of 100%. Laparoscopy is more cost effective than negative laparotomy. Laparoscopy can be performed safely and effectively on stable patients with penetrating abdominal trauma. The most important advantages are reduction of morbidity, accuracy in detecting diaphragmatic and intestinal injuries, and elimination of prolonged hospitalization for observation, so reducing the length of stay and increasing cost effectiveness.

    Colorectal polyps are common in children. The purpose of this report was to describe a clinical experience with colorectal polyps at the Beijing Children's Hospital and to evaluate the diagnostic value of ultrasonography in screening colorectal polyps in children. This was a retrospective medical record review of 487 children with colorectal polyps managed at the Beijing Children's Hospital between August 2003 and April 2010. The mean age at presentation was 4.7 ± 2.5 years, with a male predominance (M/F ratio, 1.9:1). Most children (n = 458, 94%) presented with hematochezia associated with other symptoms, such as recurrent abdominal pain (n = 42, 8.6%), prolapse of the polyp from the anus (n = 43, 8.8%), and diarrhea (n = 10, 2.1%). Anemia was observed in 33 (6.8%) children, 4 of whom required a blood transfusion before the colonoscopy. Among the 487 patients, 352 (72.3%) patients underwent ultrasonography before the colonoscopy. Polyps were detected on 345 of 352 ultrasonographic examinations in which patients subsequently underwent colonoscopy and were found to have colonic polyps. The most common polyp locations were the sigmoid colon (n = 212, 46.1%) and the rectum (n = 174, 37.8%). Solitary polyps were identified in 421 patients (88.4%), and multiple polyps were identified in 55 (11.6%) patients. Colonoscopy complications were rare, with colonic perforation observed in 2 patients and postcolonoscopy hemorrhage observed in 1 patient. The available pathology records showed that the most frequent histological type was juvenile polyps (n = 435, 91.8%), followed by Peutz-Jeghers polyps (n = 17, 3.6%), juvenile polyposis (n = 14, 3.0%), hamartomas (n = 6, 1.3%), familial adenomatous polyposis (n = 1, 0.2%), and inflammatory polyps (n = 1, 0.2%). Ultrasonic examination is a valid, accurate, and safe technique for screening colorectal polyps in children; and a full colonoscopy should be performed to remove the polyp(s) as soon as possible.

    1991-12-31

    The present study was performed to compare the clinical value of urography and ultrasonography in a non-selected group of patients referred for urography to a university hospital. The conslusions and clinical implications of the study are as follows: Intravenous urography remains the cornerstone imaging examination in the evaluation of ureteral calculi. Ultrasonography is a valuable adjunct in cases of non- visualization of the kidneys, in distal obstruction and known contrast media allergy. When women with recurrent urinary tract infection are referred for imaging of the urinary tract, ultrasonography should be used. Ultrasonography should replace urography for screening of non-acute hydronephrosis like in female genital cancer and benign prostate hyperplasia. There is good correlation between urography and ultrasonography in assessing the degree of hydronephrosis. However, more researh on the relationship between hydronephrosis and obstruction is necessary. Ultrasonography should be used as the only imaging method of the upper urinary tract in patients with microscopic hematuria. In patients less than 50 years with macroscopic hematuria, ultrasonography should be used as the only imaging of the upper urinary tract, and an examination of the urinary bladder should be included. In patients over 50 years, urography supplied with ultrasonography should be used, but more research is necessary on the subject of imaging method and age. 158 refs.

    Conclusions: Though thyroid ultrasonography failed to diagnose 67% of ectopic cases and nonfunctioning thyroid gland, it had the ability to determine the anatomy of thyroid gland. So, considering some limitations of scintigraphy, we concluded that ultrasonography is a relatively appropriate imaging tool for diagnosing CH etiologies, especially in the initial phase of CH screening.

    We evaluated the ability of subtraction and dynamic MR imaging to accurately detect breast tumors. Sixty-five breast carcinomas and 24 fibroadenomas were examined by an SE pulse sequence using a 0.2 Tesla unit. Subtraction MR images were obtained every minute during dynamic study with Gd-DTPA. Almost all breast tumors were seen as very bright masses, and the margin of the mass was clearly demonstrated on subtraction MR images. Breast carcinomas and fibroadenomas showed characteristic time-intensity curves on dynamic study. Time-intensity curves of the early peak type and plateau type were seen in 97% of breast carcinomas, while the gradually increasing type was seen in 92% of fibroadenomas. The detectability of breast carcinoma was 98% by MRI, 98% by ultrasonography, and 87% by mammography. That of fibroadenoma was 95% by MRI, 91% by ultrasonography and 60% by mammography. Sensitivity and specificity for breast carcinoma were 98% and 92% for MRI and 97% and 71% for ultrasonography. For fibroadenoma, they were 96% and 98% for MRI and 89% and 92% for ultrasonography.

    A drawback in ultrasonography, an indispensable technique in imaging ovarian malignancies, is that it sometimes shows false positive for benign tumors including dermoid cyst and ovarian endometriosis. To overcome this, the concurrent use of X-Ray CT seems warrantable and this led us to carry out the study summarized below. CT was carried out on 268 of 322 ovarian disease cases which had undergone ultrasonography. The results obtained were as follows. Sensitivity of ultrasonography and CT in ovarian malignancies were 82 % and 88 % respectively. Of the cases subjected to both techniques, those who were deemed false positive were 39 in ultrasonography and 12 in CT. Ultrasonographic imagings of dermoid cyst and ovarian endometriosis were classified on the basis of their patterns. The results obtained revealed that those in which it was difficult to discriminate the image from ovarian malignancy were types V and VI in dermoid cyst and type III-C in ovarian endometriosis. In both dermoid cyst and ovarian endometriosis, nearly a 100 % accuracy rate was obtainable with CT for diagnosis of benign tumors. This strongly suggested that concurrent use of CT was required, in diagnosing ovarian diseases with the V or VI and III-C patterns referred to above. (author)

    Intraoperative ultrasonography (IOUS) of the liver has been used both as an aid for intraoperative anatomical definition and for the detection of new lesions. The present study aimed to evaluate the impact of IOUS and to identify factors that can predict the detection of new lesions intraoperatively. In this observational and prospective study, with a cross-sectional design, patients with colorectal cancer metastases who underwent hepatectomy were selected. Abdominal computed tomography, magnetic resonance imaging, and positron emission tomography were the preoperative evaluation tests. All patients underwent IOUS performed by the same surgeon. The intraoperative findings were compared with the preoperative tests results. In total, 56 hepatectomies were evaluated. Half of the patients were men, with a mean age of 57 (30-85) years. New lesions were found intraoperatively in 12 patients (21.4% of cases) and were detected on both palpation and ultrasonography in 11 of these patients. Ultrasonography helped to revise the surgical plans by providing additional information in 35.7% of cases. On multivariate analysis, the presence of more than 4 preoperative nodules was predictive of the intraoperative occurrence of new lesions. IOUS remains the only way to evaluate the relationships between tumors, liver vascular structures, and bile ducts intraoperatively. Alone, IOUS was not useful for identifying new lesions intraoperatively, as all new lesions were also detected on palpation. The number of lesions diagnosed on preoperative tests influenced the probability of identifying new lesions intraoperatively. There may be additional influential factors.

    Full Text Available Objective: To study the clinical value of routine ultrasound combined with endoscopic ultrasonography in judging ulcerative colitis. Methods: A total of 60 cases of patients with ulcerative colitis were collected as observation group of research and 60 cases of healthy volunteers were collected as control group of research. Intestinal wall thickness was detected by white light endoscopy, abdominal intestinal ultrasound and endoscopic ultrasonography; TNF-α, IL-1β, IL-4 and IL-10 contents were detected by Elisa kit; Th1, Th2, Th17 and Treg ratios were detected by flow cytometry. Results: (1 intestinal wall thickness: intestinal wall thickness of both active UC patients and quiescent UC patients was significantly higher than that of control group, intestinal wall thickness of active UC patients was significantly higher than that of quiescent UC patients and the higher the degree of activity, the higher the intestinal wall thickness; (2 inflammatory mediators: TNF-α and IL-1β contents in intestinal mucosa of active UC patients were higher than those of quiescent UC patients and positively correlated with intestinal wall thickness; IL-4 and IL-10 contents were lower than those of quiescent UC patients and negatively correlated with intestinal wall thickness; (3 T cell contents: Th1 and Th17 cell contents in intestinal mucosa of active UC patients were higher than those of quiescent UC patients and positively correlated with intestinal wall thickness; Th2 and Treg cell contents in intestinal mucosa of active UC patients were lower than those of quiescent UC patients and negatively correlated with intestinal wall thickness. Conclusion: Routine ultrasound combined with endoscopic ultrasonography can accurately determine the severity of ulcerative colitis; measured intestinal wall thickness is closely correlated with the degree of inflammation and abnormal immune response.

    Full Text Available A 61-year-old man presented with high fever, and severe back and abdominal pain following transrectal ultrasonography (TRUS-guided prostate biopsy. Diagnosis of spondylodiscitis and psoas abscesses was made based on MRI images of the lumbar tract of the spine. Six-month broad-spectrum antibiotic treatment and immobilization with a girdle overcame the disease without any relapse at the 1-year follow-up. Spondylodiscitis after TRUS-guided prostate biopsy is a rare event, which is not yet included as a major complication of the procedure. It is probably due to the presence of fluoroquinolone-resistant bacteria in faeces. It is, therefore, important to highlight this possibility and to stress the use of targeted antibiotic prophylaxis after rectal flora swabbing with selected antibiotics at sufficient concentrations to be effectiv

    2014-06-01

    Educational Objectives and Key Points. 1. Given that abdominal hernias are a frequent imaging finding, radiologists not only are required to interpret the appearances of abdominal hernias but also should be comfortable with identifying associated complications and postrepair findings. 2. CT is the imaging modality of choice for the assessment of a known adult abdominal hernia in both elective and acute circumstances because of rapid acquisition, capability of multiplanar reconstruction, good spatial resolution, and anatomic depiction with excellent sensitivity for most complications. 3. Ultrasound is useful for adult groin assessment and is the imaging modality of choice for pediatric abdominal wall hernia assessment, whereas MRI is beneficial when there is reasonable concern that a patient\\'s symptoms could be attributable to a hernia or a musculoskeletal source. 4. Fluoroscopic herniography is a sensitive radiologic investigation for patients with groin pain in whom a hernia is suspected but in whom a hernia cannot be identified at physical examination. 5. The diagnosis of an internal hernia not only is a challenging clinical diagnosis but also can be difficult to diagnose with imaging: Closed-loop small-bowel obstruction and abnormally located bowel loops relative to normally located small bowel or colon should prompt assessment for an internal hernia.

    2002-03-01

    To compare ultrasonography (US) and plain radiography with intravenous urography (IVU) in predicting ureteral obstruction after in situ extracorporeal shock wave lithotripsy (ESWL) for ureteral stones. From April 1998 to September 2000, 100 consecutive patients with solitary ureteral stones were treated by primary in situ ESWL. ESWL failures were salvaged by ureteroscopic lithotripsy. Ninety-three patients completed the follow-up assessment. US and IVU were performed when plain radiography showed no residual stone. The occurrence of hydronephrosis on US was compared with IVU, the reference standard for ureteral obstruction. Of the 93 patients, 72 were men and 21 women (mean age 52 years; mean stone size 11.2 mm). ESWL successfully treated 70 ureteral stones (75%), and the 23 failures were treated by ureteroscopic lithotripsy. Sixty-nine patients without hydronephrosis on US had no ureteral obstruction on IVU. Of the 24 patients who had hydronephrosis on US, 8 had ureteral obstruction on IVU. Of the 85 patients who had no ureteral obstruction on IVU, 69 patients showed no evidence of hydronephrosis on US. However, all patients with ureteral obstruction on IVU demonstrated hydronephrosis on US. The sensitivity, specificity, and positive and negative predictive value concerning sonographic hydronephrosis in the prediction of ureteral obstruction was 100%, 81%, 33%, and 100%, respectively. US alone could not define the cause of ureteral obstruction. Plain abdominal radiography plus US is highly sensitive for screening ureteral obstruction after primary in situ ESWL for ureteral calculi. It can save up to 74% of patients from the potential risk of IVU. The detection of the cause of obstruction by IVU is only necessary when sonographic evidence of hydronephrosis is present.

    Full Text Available Introduction: Traumatic chest injuries (TCI are one of the most common causes of referring to the emergency departments, with high mortality and disability. This study was designed to evaluate the diagnostic accuracy of ultrasonography versus chest X ray (CXR in detection of hemo-pneumothorax for patients suffering penetrating TCI. Methods: The present cross-sectional study was performed to evaluate the diagnostic accuracy of ultrasonography in penetrating TCI victims referred to the emergency department of Shahid Kashani and Alzahra hospitals of Isfahan, Iran, from July 2012 to June 2013. Bedside ultrasonography and plain CXR was done on arrival and three hours after admission. The results of ultrasonography and radiography were separately evaluated by an emergency medicine specialist and a radiologist, who were blind to the aims of the study. Then, sensitivity, specificity, positive predictive value (PPV, negative predictive value (NPV, and kappa coefficient was considered to evaluate the accuracy of ultrasonography. Results: In this research 64 patients with penetrating chest trauma were assessed (98.4% male. The mean age of them was 25.6±8.5 years (rang: 13-65. The plain radiography revealed the eight (12.5 % cases of pneumothorax and one (1.6% hemothorax. The findings of primary ultrasonography also showed the same number of hemo-pneumothorax. Sensitivity and specificity of primary ultrasound in diagnosis of pneumothorax were 100% (95% Cl: 60.7- 100 and 100.0% (95% Cl, 92.0% to 100.0% and in detection of hemothorax were 100% (95% Cl: 50.5-100 and 100% (95% Cl: 92.8-100, respectively. Sensitivity and specificity of ultrasound in the third hour were 100% (95% Cl: 31.3-100 and 100% (95% Cl: 91.4-100, respectively. Conclusion: Findings of the present study have shown that ultrasonography has an acceptable diagnostic accuracy in the initial assessment of patients with penetrating chest trauma. However, because of its dependency on operator

    Ultrasonography is a widely accessible imaging technique for the detection of fatty liver, but the reported accuracy and reliability have been inconsistent across studies. We aimed to perform a systematic review and meta-analysis of the diagnostic accuracy and reliability of ultrasonography for the detection of fatty liver. We used MEDLINE and Embase from October 1967 to March 2010. Studies that provided cross-tabulations of ultrasonography versus histology or standard imaging techniques, or that provided reliability data for ultrasonography, were included. Study variables were independently abstracted by three reviewers and double checked by one reviewer. Forty-nine (4720 participants) studies were included for the meta-analysis of diagnostic accuracy. The overall sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio of ultrasound for the detection of moderate-severe fatty liver, compared to histology (gold standard), were 84.8% (95% confidence interval: 79.5-88.9), 93.6% (87.2-97.0), 13.3 (6.4-27.6), and 0.16 (0.12-0.22), respectively. The area under the summary receiving operating characteristics curve was 0.93 (0.91-0.95). Reliability of ultrasound for the detection of fatty liver showed kappa statistics ranging from 0.54 to 0.92 for intrarater reliability and from 0.44 to 1.00 for interrater reliability. Sensitivity and specificity of ultrasound was similar to that of other imaging techniques (i.e., computed tomography or magnetic resonance imaging). Statistical heterogeneity was present even after stratification for multiple clinically relevant characteristics. Ultrasonography allows for reliable and accurate detection of moderate-severe fatty liver, compared to histology. Because of its low cost, safety, and accessibility, ultrasound is likely the imaging technique of choice for screening for fatty liver in clinical and population settings.

    Proforma information, instructions and procedures of training in radiology are lacking in Nigeria. To describe the errors in ultrasonography performed by unsupervised trainee radiologists. The radiology records of all ultrasound scans (USS) carried out and all reports that came back to the unit of the authors on account of misdiagnosis, doubtful diagnosis, misinformation or error in the reports were studied. The patients with the returned reports were rescanned where available by consultants and the collected data analysed. A total of 4680 patients had ultrasound studies without supervision resulting in 605 (12.93%) queried reports. The USS scans of 235 (5.02%) patients were repeated with consultants in attendance resulting in significant change in reports of 95 (2.03%) patients. Analysis of the request cards of 605 queried reports showed omission of relevant clinical information 463 (76.53%), outright wrong information 65 (10.73%),and unconventional abbreviations 139 (22.98%), while 493 (81.49%) were completed by a nurse, medical student or junior resident. Typographical errors comprised 174 (28.76%) of the 605 queried reports. False negative error was the highest type of error seen in 55 (57.89%) of the 95 patients with significant change in their report after repeat scan as lesions not detected were not documented. Trainee radiologists make significant errors in carrying out and reporting ultrasonography without adequate direct supervision of the study by their training consultants. Majority of the errors originate from lack of accurate filling of the patients request cards by the requesting physicians, lack of adequate preparation for the intended study, and typographical errors in writing reports. False negative reports are by far the greatest cause of errors recorded as lesions not detected were not documented.

    Full Text Available Ultrasound (US of the shoulder is the most commonly requested examination in musculoskeletal US diagnosis. Sports injuries and degenerative and inflammatory processes are the main sources of shoulder pain and functional limitations. Because of its availability, low cost, dynamic examination process, absence of radiation exposure, and ease of patient compliance, US is the preferred mode for shoulder imaging over other, more sophisticated, and expensive methods. Operator dependence is the main disadvantage of US examinations. Use of high range equipment with high resolution transducers, adhering to a strict examination protocol, good knowledge of normal anatomy and pathological processes and an awareness of common pitfalls are essential for the optimal performance and interpretation of shoulder US. This article addresses examination techniques, the normal sonographic appearance of tendons, bursae and joints, and the main pathological conditions found in shoulder ultrasonography.

    Full Text Available Ultrasonography (US is a useful screening method for the diagnosis of developmental dysplasia of the hip (DDH and congenital spinal anomalies in infants. In addition, US is a useful, noninvasive imaging modality for the diagnosis of transient synovitis in children. The early detection of DDH leads to a better prognosis without surgical intervention. Moreover, spinal US allows the detection of congenital malformations and can also demonstrate normal anatomy and normal variants that may resemble disorders. Therefore, radiologists should be familiar with the sonographic anatomy of the normal infant hip, scanning and measurement techniques for DDH, the US features of transient synovitis in children, spinal US techniques, and the US features of normal anatomical structures, normal variants, and congenital spinal anomalies.

    Congenital hypophosphatasia is a rare fatal skeletal dysplasia. Antenatal determinants of Epub ahead of print lethality include small thoracic circumference with pulmonary hypoplasia and severe micromelia. These features were present in the fetus of a 25-year-old female who came for an anomaly scan in her second trimester of pregnancy. Additional findings of generalized demineralization and osteochondral spurs led to the diagnosis of hypophosphatasia congenita. The pregnancy was terminated, and the findings were confirmed on autopsy. Common differential diagnoses with clues to diagnose the above mentioned condition have been discussed here. Early and accurate detection of this medical condition is important as no treatment has been established for this condition. Therefore, antenatal ultrasonography helps in diagnosing and decision making with respect to the current pregnancy and lays the foundation for the genetic counseling of the couple.

    The recent development of advanced high-resolution transducers has enabled the fast, easy, and dynamic ultrasonographic evaluation of small, superficial structures such as the finger. In order to best exploit these advances, it is important to understand the normal anatomy and the basic pathologies of the finger, as exemplified by the following conditions involving the dorsal, volar, and lateral sections of the finger: sagittal band injuries, mallet finger, and Boutonnière deformity (dorsal aspect); flexor tendon tears, trigger finger, and volar plate injuries (volar aspect); gamekeeper’s thumb (Stener lesions) and other collateral ligament tears (lateral aspect); and other lesions. This review provides a basis for understanding the ultrasonography of the finger and will therefore be useful for radiologists.

  7. Fallopian tube patency demonstrated at ultrasonography

    Energy Technology Data Exchange (ETDEWEB)

    Rasmussen, F.; Larsen, C.; Justesen, P.

    Fallopian tube patency was assessed in 24 infertile patients by hysterosalpingography (HSG) and ultrasonographic examination of the pouch of Douglas following transcervical injection of sterile isotonic solution of NaCl. The presence of fluid in the pouch, after the injection, was taken to indicate tubal patency. The results of the HSG and the ultrasonographic diagnosis as to the presence of at least unilateral tubal patency were concordant in 21 patients. Pitfalls consisted of fluid accumulation in periadnexal adhesions, edema in the bowel wall, and spill of the injected saline into a large hydrosalpinx. Ultrasonography is advocated as the initial examination in assessing infertility in young women. If tubal patency is demonstrated, the patient should be recommended a six month trial period, to become pregnant, before invasive procedures are initiated.

    Full Text Available Breast ultrasonography (US is currently considered the first-line examination in the detection Epub ahead of print and characterization of breast lesions. However, conventional handheld US (HHUS has several limitations such as operator dependence and the requirement of a considerable amount of radiologist time for whole-breast US. Automated breast US (ABUS, recently approved by the United States Food and Drug Administration for screening purposes, has several advantages over HHUS, such as higher reproducibility, less operator dependence, and less required physician time for image acquisition. In addition, ABUS provides both a coronal view and a relatively large field of view. Recent studies have reported that ABUS is promising in US screening for women with dense breasts and can potentially replace handheld second-look US in a preoperative setting.

    The aim of this study was to describe the MRI features of abdominal tuberculous lymphadenopathy. MRI studies of 13 patients with abdominal tuberculous lymphadenopathy were reviewed with regard to anatomic distribution and size. Signal intensities, in relation to abdominal wall muscle, on unenhanced T1- and T2-weighted images and patterns of contrast enhancement of lymphadenopathy were evaluated in each patient. In each patient, the largest lymph node with the same imaging characteristic was evaluated. The upper paraaortic region was the most common site of involvement (n=12 patients), followed by the lesser omentum (n=10 patients), the anterior pararenal space (n=9 patients), the lower paraaortic area (n=8 patients), the small bowel mesentery (n=6 patients), the greater omentum (n=2 patients) and the originating site of the inferior mesenteric artery (n=2 patients). The mean lymph node size was 1.8 cm (range 0.5-5 cm). The overall mean lymph node number per patient was 16 (range 2-50). A total of 41 lymph nodes were evaluated in 13 patients. On T2-weighted images, 40 lesions were hyperintense and one lesion was isointense. Nine hyperintense lesions showed a hypointense peripheral rim and seven internal heterogeneity. Perinodal T2-hyperintensity was present in 23 lesions. The latter finding was valid for all patients. On T1-weighted images, 30 lesions were hypointense and 11 isointense. Nine hypointense lesions demonstrated a hyperintense peripheral rim, and six were heterogeneous. Contrast-enhanced fat-suppressed T1-weighted images demonstrated predominant peripheral enhancement in 28 lesions: (1) peripheral uniform, thin (n=19); (2) thick irregular, complete (n=3); and (3) conglomerate group of nodes showing peripheral and central areas of rim enhancement (n=6). Heterogeneous and homogeneous enhancement was present in ten and three lesions, respectively. Combinations of enhancing patterns in the same nodal group and different nodal groups were seen in eight and

    Ultrasonography is most common utilized diagnostic tool in obstetric and gynecology for the evaluation of patient with a pelvic mass or pregnancy. For it is characterized by no radiation hazard, noninvasive examination and high diagnostic accuracy. Also it affords an accurate assessment of the presence, size, location and internal consistency of a pelvic mass. The recent availability and improved resolution of realtime scanning have afforded a more flexible and complete approach to evaluation of normal and abnormal structures in the pelvis. We analyzed ultrasonographic findings in 154 pathologically proven cases of pelvic mass examined at Korea General Hospital from January 1983 to April 1984. The results were as follows: 1. The age distribution was from 12 years to 66 years and the majority of patients were between the ages of 21 and 51 years (91.4%). 2. The incidence of pelvic mass was 27.9% in uterine leiomyoma, 22.7% in ovarian cyst, 13.0% in adenomyosis and 8.4% in serous cystadenoma. 3. Mild to moderately echogenic nodular uterine enlargement with some cystic change (81.4%) of leiomyoma and multiple small vesicular pattern of intrauterine contents with uterine enlargement of H-mole were the most common ultrasonographic findings. The location and type of leiomyoma were most common in the fundus and body (95.3%), and intramural myoma (53.5%). The most frequent findings of ovarian teratoma was cystic mass with echogenic focus (41.7%) but the echogenic appearance of the lesions was extremely variable.The ultrasonographic findings of ectopic pregnancy were cystic or complex adnexal mass (80.0%), with or without fluid in cul-de-sac and deviation of uterus by adnexal mass. 4. Accuracy of ultrasonography i determining the overall correct diagnosis of the pelvic masses compared with proven diagnosis was approximately 61.7%. The diagnostic accuracy was 90.7% in uterine leiomyoma, 100% in H-mole and 80.0% in ectopic pregnancy.

    High resolution ultrasonography is a non-painful and non-invasive imaging technique which is useful for the assessment of shoulder pain causes, as clinical examination often does not allow an exact diagnosis. The aim of this study was to compare the findings of clinical examination and high resolution ultrasonography in patients presenting with painful shoulder. Non-interventional observational study of 100 adult patients suffering from unilateral shoulder pain. Exclusion criteria were shoulder fractures, prior shoulder joint surgery and shoulder injections in the past month. The physicians performing the most common clinical shoulder examinations were blinded to the results of the high resolution ultrasonography and vice versa. In order to detect pathology of the m. supraspinatus tendon, the Hawkins and Kennedy impingement test showed the highest sensitivity (0.86) whereas the Jobe supraspinatus test showed the highest specificity (0.55). To identify m. subscapularis tendon pathology the Gerber lift off test showed a sensitivity of 1, whereas the belly press test showed the higher specificity (0.72). The infraspinatus test showed a high sensitivity (0.90) and specificity (0.74). All AC tests (painful arc II(a), AC joint tenderness(b), cross body adduction stress test(c)) showed high specificities ((a)0.96, (b)0.99, (c)0.96). Evaluating the long biceps tendon, the palm up test showed the highest sensitivity (0.47) and the Yergason test the highest specificity (0.88). Knowledge of sensitivity and specificity of various clinical tests is important for the interpretation of clinical examination test results. High resolution ultrasonography is needed in most cases to establish a clear diagnosis.

    In stable patients with blunt abdominal trauma, accurate diagnosis of visceral injuries is crucial. To determine whether repeating ultrasound exam will increase the sensitivity of focused abdominal sonography for trauma (FAST) through revealing additional free intraperitoneal fluid in patients with blunt abdominal trauma. We performed a prospective observational study by performing primary and secondary ultrasound exams in blunt abdominal trauma patients. All ultrasound exams were performed by four radiology residents who had the experience of more than 400 FAST exams. Five routine intraperitoneal spaces as well as the interloop space were examined by ultrasound in order to find free fluid. All patients who expired or were transferred to the operating room before the second exam were excluded from the study. All positive ultrasound results were compared with intra-operative and computed tomography (CT) findings and/or the clinical status of the patients. Primary ultrasound was performed in 372 patients; 61 of them did not undergo secondary ultrasound exam; thus, were excluded from the study.Three hundred eleven patients underwent both primary and secondary ultrasound exams. One hundred and two of all patients were evaluated by contrast enhanced CT scan and 31 underwent laparotomy. The sensitivity of ultrasound exam in detecting intraperitoneal fluid significantly increased from 70.7% for the primary exam to 92.7% for the secondary exam. Examining the interloop space significantly improved the sensitivity of ultrasonography in both primary (from 36.6% to 70.7%) and secondary (from 65.9% to 92.7%) exams. Performing a secondary ultrasound exam in stable blunt abdominal trauma patients and adding interloop space scan to the routine FAST exam significantly increases the sensitivity of ultrasound in detecting intraperitoneal free fluid

    To investigate the feasibility and inter-investigator reproducibility of perineal ultrasonography in men with and without post-prostatectomy urinary incontinence (PPI). This clinical pilot study involved 33 male patients, with a mean (range) age of 67.8 (51-76) years, who underwent radical prostatectomy (RP) ≥1 year ago. We investigated 21 men with clinically and urodynamically proven grade ≥2 PPI and compared them with 12 men without PPI in objective testing as well as in validated questionnaires. We used an abdominal 3.5-5 MHz ultrasound probe, which was placed at the perineum between scrotum and anus. With the help of three-/four-dimensional (3D/4D) multislice imaging we obtained good visualization of the bladder neck, the urethra and pelvic floor muscle contraction. The data from all 33 men was evaluated by two investigators and archived images and videos were also analysed by two independent investigators not present at the actual investigation. Using perineal ultrasonography we were able to visualize hypermobility of the proximal urethra, funnelling of the bladder neck, voluntary pelvic floor contraction, urethral and paraurethral fibrosis, and suture or sling material. Men with and without PPI differed mainly in the degree of hypermobility of the proximal urethra and opening of the bladder neck. Inter-investigator agreement was 100% in assessing paraurethral tissue and voluntary muscle contraction and 94% in quantifying mobility of the proximal urethra. We were able to evaluate the bladder neck opening in 85% of the men. There was 82% agreement between the initial investigators in evaluation of the bladder neck and 76% in quantifying mobility of the proximal urethra using retrospective analysis of stored images. Two-dimensional and 3D/4D perineal ultrasonography provides more insight into the diagnosis of men with PPI. Perineal ultrasonography can be used further as a visual aid for biofeedback to teach correct muscle contraction of men with stress

METHODS: the IUS thickness measurement of 30 women, between the 36th and 39th weeks of gestation with previous caesarean section, done by two observers, was studied. Abdominal ultrasonography with the patient in both supine and lithotomy position was performed. In the sagittal section, the IUS was identified and four bidimensional images and two tridimensional blocks of the total thickness were collected through the abdominal route, and the same for the muscle layer, through the vaginal route. Tridimensional acquisitions were manipulated in the multiplanar mode. The time was measured with a chronometer. Reproducibility was evaluated by the computation of the absolute difference between measurements, the ratio of differences smaller than 1 mm, the intraclass coefficient (ICC, and the Bland and Altman's concordance limits. RESULTS: the average bidimensional measurement of IUS thickness was 7.4 mm through the abdominal and 2.7 mm through the vaginal route, and the tridimensional measurement was 6.9 mm through the abdominal and 5.1 mm through the vaginal route. Intra- and interobserver reproducibility of vaginal versus abdominal route: smaller absolute difference (0.2-0.4 mm versus 0.8-1.5 mm, greater ratio of differences (85.8-97.8% versus 48.7-72,8%, with p0.05[A1] and similar lower concordance limits (-38 to 3.4 versus -3.6 to 4 mm for tridimensional ultrasonography and ICC (0.6-0.9 versus 0.7-0.9. CONCLUSIONS: from the above, we came to the conclusion that the measurement of the IUS muscle layer, through the vaginal route using tridimensional ultrasonography is more reproducible

    Full Text Available BACKGROUND In the recent times there has been increased incidence of abdominal trauma cases due to several causes. Quick and prompt intervention is needed to decrease the mortality of the patients. So we conducted a study to assess the cause and the management of abdominal trauma cases in our institution. The aim of this study was to know the incidence of blunt and penetrating injuries and their causes, age and sex incidence, importance of various investigations, mode of treatment offered and post-operative complications. To study the cause of death and evolve better management. MATERIALS AND METHODS The present study comprises of patients admitted to and operated in various surgical units in the Department of Surgery at Government General Hospital, attached to Guntur Medical College Guntur, from August 2014 to October 2016. RESULTS Increase incidence seen in age group 20-29 years (30%. Male predominance 77.5%. Mechanism of injury–road traffic accidents 65%. Isolated organ injury–colon and rectum 40%. Other associated injuries–chest injuries with rib fractures 7.5%. Complications–wound infection 17.5%. Duration of hospital stay 8–14 days. Bowel injury management–closure of perforation 84.6%. Resection anastomosis 15.38%. CONCLUSION Thorough clinical examination, diagnostic paracentesis, plain X-ray erect abdomen and ultrasound proved to be very helpful in the diagnosis of intra-abdominal injuries. Spleen is the commonest organ involved in blunt trauma and colon is the commonly injured organ in penetrating abdominal trauma, many patients have associated extremity and axial skeleton injuries. With advances in diagnosis and intensive care technologies, most patients of solid visceral injuries with hemodynamic stability can be managed conservatively. Surgical site infection is the most common complication following surgery. The mortality is high; reason might be patient reaching the hospital late, high incidence of postoperative septic

    In the last decade, laparoscopy has been the most innovative surgical movement in general surgery. Minimally invasive surgery performed through a few small incisions, laparoscopy is the standard of care for the treatment of gallbladder disease and the gold standard for the treatment of reflux disease. The indications for a laparoscopic approach to abdominal disease continue to increase, and many diseases may be treated with laparoscopic techniques. At Ochsner, laparoscopic techniques have dem...

    Full Text Available Abdominal elephantiasis is a rare entity. Abdominal elephantiasis is an uncommon, but deformative and progressive cutaneous disease caused by chronic lymphedema and recurrent streptococcal or Staphylococcus infections of the abdominal wall. We present 3 cases of patients with morbid obesity who presented to our hospital with abdominal wall swelling, thickening, erythema, and pain. The abdominal wall and legs were edematous, with cobblestone-like, thickened, hyperpigmented, and fissured plaques on the abdomen. Two patients had localised areas of skin erythema, tenderness, and increased warmth. There was purulent drainage from the abdominal wall in one patient. They were managed with antibiotics with some initial improvement. Meticulous skin care and local keratolytic treatment for the lesions were initiated with limited success due to their late presentation. All three patients refused surgical therapy. Conclusion. Early diagnosis is important for the treatment of abdominal elephantiasis and prevention of complications.

    The aim of this study was to assess the accuracy of ultrasonography in the diagnosis of chronic lateral ankle ligament injury. A total of 120 ankles in 120 patients with a clinical suspicion of chronic ankle ligament injury were examined by ultrasonography by using a 5- to 17-MHz linear array transducer before surgery. The results of ultrasonography were compared with the operative findings. There were 18 sprains and 24 partial and 52 complete tears of the anterior talofibular ligament (ATFL); 26 sprains, 27 partial and 12 complete tears of the calcaneofibular ligament (CFL); and 1 complete tear of the posterior talofibular ligament (PTFL) at arthroscopy and operation. Compared with operative findings, the sensitivity, specificity and accuracy of ultrasonography were 98.9%, 96.2% and 84.2%, respectively, for injury of the ATFL and 93.8%, 90.9% and 83.3%, respectively, for injury of the CFL. The PTFL tear was identified by ultrasonography. The accuracy of identification between acute-on-chronic and subacute-chronic patients did not differ. The accuracies of diagnosing three grades of ATFL injuries were almost the same as those of diagnosing CFL injuries. Ultrasonography provides useful information for the evaluation of patients presenting with chronic pain after ankle sprain. Intraoperative findings are the reference standard. We demonstrated that ultrasonography was highly sensitive and specific in detecting chronic lateral ligments injury of the ankle joint.

    To investigate the use of ultrasonography to assess nonunion of fractures in dogs and to compare results of ultrasonography, radiography, and histologic examination. 8 nonunion fractures in 6 dogs (1 each in 5 dogs and 3 in 1 dog); dogs ranged from 7 to 94 months of age and weighed 6 to 30 kg. Diagnostic assessment consisted of complete clinical and orthopedic examinations, radiography, B-mode (brightness mode) ultrasonography, and power Doppler ultrasonography. Biopsy samples were obtained during surgery for histologic examination. They were stained with H&E and immunolabeled by use of anti-CD31 antibodies. Correlations of power Doppler score, power Doppler count, vessel area, and radiographic prediction with the mean number of vessels counted per hpf were derived. Radiographically, 7 of 8 nonunion fractures were diagnosed as atrophic and were therefore estimated to be nonviable. Vascularity of nonunion fractures during power Doppler ultrasonography ranged from nonvascularized to highly vascularized. Absolute vessel count during histologic examination ranged from 0 to 63 vessels/hpf; 5 nonunion sites had a mean count of > 10 vessels/hpf. Vascularity during power Doppler ultrasonography was highly correlated with the number of vessels per hpf, whereas the correlation between the radiographic assessment and histologic evaluation was low. Radiographic prediction of the viability of nonunion fractures underestimated the histologically assessed vascularity of the tissue. Power Doppler ultrasonography provided a more accurate estimation of the viability of the tissue and therefore the necessity for debridement and autografts during revision surgery.

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

    Abdominal emergencies during pregnancy (excluding obstetrical emergencies) occur in one out of 500-700 pregnancies and may involve gastrointestinal, gynecologic, urologic, vascular and traumatic etiologies; surgery is necessary in 0.2-2% of cases. Since these emergencies are relatively rare, patients should be referred to specialized centers where surgical, obstetrical and neonatal cares are available, particularly because surgical intervention increases the risk of premature labor. Clinical presentations may be atypical and misleading because of pregnancy-associated anatomical and physiologic alterations, which often result in diagnostic uncertainty and therapeutic delay with increased risks of maternal and infant morbidity. The most common abdominal emergencies are acute appendicitis (best treated by laparoscopic appendectomy), acute calculous cholecystitis (best treated by laparoscopic cholecystectomy from the first trimester through the early part of the third trimester) and intestinal obstruction (where medical treatment is the first-line approach, just as in the non-pregnant patient). Acute pancreatitis is rare, usually resulting from trans-ampullary passage of gallstones; it usually resolves with medical treatment but an elevated risk of recurrent episodes justifies laparoscopic cholecystectomy in the 2nd trimester and endoscopic sphincterotomy in the 3rd trimester. The aim of the present work is to review pregnancy-induced anatomical and physiological modifications, to describe the main abdominal emergencies during pregnancy, their specific features and their diagnostic and therapeutic management.

    Prefumo, Federico; Izzi, Claudia

    2014-04-01

    The most common fetal abdominal wall defects are gastroschisis and omphalocele, both with a prevalence of about three in 10,000 births. Prenatal ultrasound has a high sensitivity for these abnormalities already at the time of the first-trimester nuchal scan. Major unrelated defects are associated with gastroschisis in about 10% of cases, whereas omphalocele is associated with chromosomal or genetic abnormalities in a much higher proportion of cases. Challenges in management of gastroschisis are related to the prevention of late intrauterine death, and the prediction and treatment of complex forms. With omphalocele, the main difficulty is the exclusion of associated conditions, not all diagnosed prenatally. An outline of the postnatal treatment of abdominal wall defects is given. Other rarer forms of abdominal wall defects are pentalogy of Cantrell, omphalocele, bladder exstrophy, imperforate anus, spina bifida complex, prune-belly syndrome, body stalk anomaly, and bladder and cloacal exstrophy; they deserve multidisciplinary counselling and management.

    2015-04-01

    Full Text Available Purpose: The aim of this study was to validate a computational fluid dynamics (CFD simulation of flow-diverter treatment through Doppler ultrasonography measurements in patient-specific models of intracranial bifurcation and side-wall aneurysms. Methods: Computational and physical models of patient-specific bifurcation and sidewall aneurysms were constructed from computed tomography angiography with use of stereolithography, a three-dimensional printing technology. Flow dynamics parameters before and after flow-diverter treatment were measured with pulse-wave and color Doppler ultrasonography, and then compared with CFD simulations. Results: CFD simulations showed drastic flow reduction after flow-diverter treatment in both aneurysms. The mean volume flow rate decreased by 90% and 85% for the bifurcation aneurysm and the side-wall aneurysm, respectively. Velocity contour plots from computer simulations before and after flow diversion closely resembled the patterns obtained by color Doppler ultrasonography. Conclusion: The CFD estimation of flow reduction in aneurysms treated with a flow-diverting stent was verified by Doppler ultrasonography in patient-specific phantom models of bifurcation and side-wall aneurysms. The combination of CFD and ultrasonography may constitute a feasible and reliable technique in studying the treatment of intracranial aneurysms with flow-diverting stents.

    Objective: This study was designed to evaluate the validity of colour Doppler ultrasonography with D-dimers in clinically suspected deep venous thrombosis of the lower limb. Study Design: Validation study Place and Duration of study: Radiology Department CMH/MH Rawalpindi Six months from 15 June 2006 to 31 December 2006. Subjects and Methods: Thirty cases of clinically suspected deep venous thrombosis of the lower limb were included in the study selected on non probability convenience sampling technique. Colour Doppler ultrasonography examination of the affected lower limb was carried out and results compared with D-dimers assays results. Results: Among 30 patients who underwent colour Doppler ultrasonography examination of the affected limb for diagnosis of deep venous thrombosis, 27 (90%) were diagnosed to have deep venous thrombosis, 3 (10%) were diagnosed not to have deep venous thrombosis. Amongst them 2 patients had raised D-dimers levels and repeat Doppler ultrasound advised. On revised ultrasound deep venous thrombosis in these patients was confirmed. This showed that colour Doppler ultrasonography examination has sensitivity of 93.1%, specificity 100%, positive predictive value 100%, negative predictive value 33.33% and overall accuracy of 93.33 %. Conclusion: Colour Doppler ultrasonography has a high diagnostic yield in cases of deep venous thrombosis of lower limb when used in conjunction with D-dimers assays. (author)

    To evaluate the precision of both two- and three-dimensional ultrasonography in determining vertebral lesion level (the first open vertebra) in patients with spina bifida. This was a prospective longitudinal study comprising of fetuses with open spina bifida who were treated in the fetal medicine division of the department of obstetrics of Hospital das Clínicas of the Universidade de São Paulo between 2004 and 2013. Vertebral lesion level was established by using both two- and three-dimensional ultrasonography in 50 fetuses (two examiners in each method). The lesion level in the neonatal period was established by radiological assessment of the spine. All pregnancies were followed in our hospital prenatally, and delivery was scheduled to allow immediate postnatal surgical correction. Two-dimensional sonography precisely estimated the spina bifida level in 53% of the cases. The estimate error was within one vertebra in 80% of the cases, in up to two vertebrae in 89%, and in up to three vertebrae in 100%, showing a good interobserver agreement. Three-dimensional ultrasonography precisely estimated the lesion level in 50% of the cases. The estimate error was within one vertebra in 82% of the cases, in up to two vertebrae in 90%, and in up to three vertebrae in 100%, also showing good interobserver agreement. Whenever an estimate error was observed, both two- and three-dimensional ultrasonography scans tended to underestimate the true lesion level (55.3% and 62% of the cases, respectively). No relevant difference in diagnostic performance was observed between the two- and three-dimensional ultrasonography. The use of three-dimensional ultrasonography showed no additional benefit in diagnosing the lesion level in the fetuses with spina bifida. Errors in both methods showed a tendency to underestimate lesion level. Thieme Publicações Ltda Rio de Janeiro, Brazil.

    Full Text Available Background: Sickle cell disease is characterized by repeated crisis and need for frequent transfusions. Abdominal crisis are common and potentially can damage any abdominal organ. Screening for organ involvement will lead to early detection and better patient care. Aim and Objectives: To see whether ultrasound can be a better noninvasive technique for early detection of organ involvement. Material and Methods: Prospective cross sectional observational study done on patients admitted in pediatric ward of a medical college. Total of 150 patients, already diagnosed to have sickle cell anemia (homozygous 110 and heterozygous 40 was included in the study. All the patients were in steady state. Demographic, clinical biochemical details were noted and were subjected to ultrasonography. Renal artery, Being end artery, Doppler study was also done. All the modalities were compared for early detection. Results: Majority of patients (77% were between 1 to 30 years with male female ratio of 2:1. Recurrent fever (64% and recurrent abdominal pain (47% were most common symptoms and anemia (66%, hepatomegaly (62%, splenomegaly (21% were most common signs. When clinical examination, biochemical tests and ultrasonography were compared for organ detection, ultrasound significantly detected more patients (p=<0.05. Ultrasonography of kidney included renal doppler also. Renal involvement by microalbuminuria measurement was of same as ultrasonography. Organ involvement increased with age. Conclusion: Ultrasonography was good noninvasive technique for organ detection but kidneysyield was better with Doppler study. Most common organ found to be affected was liver. Involvement increased with age. Early detection helps clinicians to avoid drugs toxic to involved organs.

    Twenty-six patients with chief complaint of shoulder pain who underwent both ultrasonographic examination and arthrography of the shoulder were analyzed. Ten out of 12 cases with clinical impression of frozen shoulder, showed normal findings on the ultrasonographic examination of the shoulder. Among these ten cases, nine cases showed adhesive capsulitis and one case showed rotator cuff tear on arthrography. Among six cases with the clinical impression of rotator cuff tear, five cases showed rotator cuff tear and one case showed combined calcific tendinitis and adhesive capsulitis on ultrasonographic examination. In arthrography, four cases of rotator cuff tear, one case of calcific tendinitis and biceps tendinitis and one case of normal finding were diagnosed. For the remaining eight cases in the ultrasonographic examination, normal finding or biceps tendinitis were found and for the remaining of the cases in arthrography adhesive capsulitis were found. With the above results, we recommend that the shoulder ultrasonography as the first line diagnostic modality for a patient with chief complaint of shoulder pain.

    1987-01-01

    Twenty six patients were studied with 67 Gallium to detect and localize the site of intra-abdominal and intraperitoneal infection. They were divided in two groups: a) with and b) without physical symptoms that could localize an abcess in the abdominal cavity. All the patients with suppuration had persistent up-take of 67 Ga in one anatomic area of the abdomen, subsequently documented by computarized axial tomography (CAT) in 58% of the cases or by laparotomy in 88% of them. Scintigraphy with 67 Ga in the patients with recent surgery not only detected focal infection in 67% of the cases but excluded subphernic collection. In 78% of patients with prolonged fever, the infection was localized. There was no false positive result. The comparison in 56% of the cases with CAT demonstrated that both techniques are 100% sensitive for the diagnosis of abdominal suppurative processes. Three of the 26 patients, after six weeks of medical treatment, were restudied with 67 Ga and CAT, showing total resolution of their previous abnormalities. It is concluded that 67 Ga scintigraphy performed as the first study in febrile patients independent of the presence or absence of physical symptoms that could localize the abdominal infection, is sensitive for the detection and localization of an abdominal abscess and that a negative result excludes it.

    The purpose of this study was to describe the ultrasonographic features and assess the diagnostic value of sonography in the evaluation of children with Henoch-Schonlein purpura. Between October 1993, and Febuary 1998, 67 children with Henoch-Schonlein purpura underwent abdominal ultrasonography, which in 13 was used for follow up. Bowel wall thickness and location, pattern of color Doppler signal in the thickened bowel wall, the size and location of enlarged mesenteric lymph node and the presence of ascites were evaluated. In 42 cases(63%), sonographic findings were positive, and indicated mesenteric lymphadenopathy(n=3D21), small bowel wall thickening(n=3D20), and ascites(n=3D17). Thickened bowels were demonstrated at the ileum in 11 cases, the jejunum in five, the duodenum in one, and combined wall thickening at the duodenum and jejunum in two;thickening of the duodenum and ileum was seen in one case. Thickness varied from 3 to 10 mm(mean:6.5 mm). On follow-up sonography, regression of bowel wall thickening was observed earlier than that of mesenteric lymphadenopathy or ascites, and correlated well with improved abdominal symptoms. Abdominal ultrasonographic manifestations of Henoch-Schonlein purpura were bowel wall thickening, mesentric lymphadenopathy and ascites. Sonography was a simple and useful method for the evaluation of gastrointestinal manifestation of Henoch-Schonlein purpura.=20.

    Treatments for primary hyperparathyroidism due to adenoma, hyperplasia and carcinoma and secondary hyperparathyroidism are mainly surgical resections of them. Accurate imaging diagnoses of the existences and the regions are very important for reductions of invasiveness. We describe ultrasonography and (99m)Tc-MIBI scintigraphy of hyperparathyroidism. We explain an advantage, a disadvantage and diagnosability of these modalities. We mention utilities of SPECT/CT, too. We show echogram and (99m)Tc-MIBI scintigraphy images about 3 cases of hyperparathyroidism.

  20. Abdominal respiratory motor pattern in the rat.

    Science.gov (United States)

    Iizuka, Makito

    2010-01-01

    In this brief review, I focused on the abdominal expiratory motor pattern in the rat. In the vagotomized adult rat, hypercapnic acidosis evoked two patterns of the abdominal expiratory activity; one with low amplitude expiratory discharge (E-all activity) that persisted throughout the expiratory phase, and another with late expiratory and high amplitude bursts (E2 activity) superimposed on the E-all activity. The E-all activity appeared from milder acidosis than the E2 activity. In the anesthetized, vagotomized or vagus-intact neonatal rats, abdominal muscles often showed not only E2 activity but also a smaller additional burst occurred just after the termination of diaphragmatic inspiratory activity (E1 activity). Since this E1 activity is rarely observed in the adult rat, the abdominal respiratory motor pattern likely changes during postnatal development. Under light anesthesia, vagal afferent feedback shortened the respiratory cycle period due to shortening of the expiratory duration. Further decrement in depth of anesthesia changed the biphasic E2+E1 abdominal motor activity pattern to E-all activity pattern in the vagus-intact neonatal rat. Since this E-all activity was typically observed with short cycle period in the vagus-intact neonatal rat, relation with the E-all activity in the vagotomized adult rat remained unknown. The vagal feedback should have roles not only in setting the cycle period short but also shaping the expiratory motor pattern in the neonatal rat. Although abdominal muscles in the in vitro preparation from neonatal rat also showed biphasic E2+E1 activity, E2 activity was shorter and/or smaller than the E1 activity.

  1. Intra-abdominal pressure and abdominal wall muscular function: Spinal unloading mechanism.

    Stokes, Ian A F; Gardner-Morse, Mack G; Henry, Sharon M

    2010-11-01

    The roles of antagonistic activation of abdominal muscles and of intra-abdominal pressurization remain enigmatic, but are thought to be associated with both spinal unloading and spinal stabilization in activities such as lifting. Biomechanical analyses are needed to understand the function of intra-abdominal pressurization because of the anatomical and physiological complexity, but prior analyses have been over-simplified. To test whether increased intra-abdominal pressure was associated with reduced spinal compression forces for efforts that generated moments about each of the principal axis directions, a previously published biomechanical model of the spine and its musculature was modified by the addition of anatomically realistic three-layers of curved abdominal musculature connected by fascia to the spine. Published values of muscle cross-sectional areas and the active and passive stiffness properties were assigned. The muscle activations were calculated assuming minimized muscle stress and stretch for the model loaded with flexion, extension, lateral bending and axial rotation moments of up to 60 Nm, along with intra-abdominal pressurization of 5 or 10 kPa (37.5 or 75 mm Hg) and partial bodyweight (340 N). The analysis predicted a reduction in spinal compressive force with increase in intra-abdominal pressurization from 5 to 10 kPa. This reduction at 60 Nm external effort was 21% for extension effort, 18% for flexion effort, 29% for lateral bending and 31% for axial rotation.

    Aberrant cervical thymus is rarely reported in adults. We report a case of solid aberrant cervical thymus in a 27 year old female, which was found incidentally on ultrasonography for the evaluation of the thyroid cancer. On ultrasonography, the lesion was found between the left thyroid and common carotid artery without any remarkable interface echo, and had similar echogenicity to the thyroid. The lesion extended to the upper pole of the left thyroid.

    Endoscopic ultrasonography (EUS) is widely used to evaluate pancreaticobiliary diseases, especially pancreatic masses. EUS has a good ability to detect pancreatic masses, but it is not sufficient for the differential diagnosis of various types of lesions. In order to address the limitations of EUS, new techniques have been developed to improve the characterization of the lesions detected by EUS. EUS-guided fine needle aspiration (EUS-FNA) has been used for diagnosing pancreatic tumors. In order to improve the histological diagnostic yield, a EUS-FNA needle with a core trap has recently been developed. Contrast-enhanced harmonic EUS is a new imaging modality that uses an ultrasonographic contrast agent to visualize blood flow in fine vessels. This technique is useful in the diagnosis of pancreatic solid lesions and in confirming the presence of vascularity in mural nodules for cystic lesions. EUS elastography analyzes several different variables to measure tissue elasticity, color patterns, and strain ratio, using analytical techniques such as hue-histogram analysis, and artificial neural networks, which are useful for the diagnosis of chronic pancreatitis and pancreatic cancer.

    The objective of our study is to assess the utility of ultrasonography in the study of the complications associated with en bloc kidney transplantation. Twenty-three recipients of double transplants from donors under the age of 3 years were studied. Ultrasound (mode B: pulsed Doppler and color Doppler) was performed within the first three postoperative days and was repeated at 6 and 12 months. The morphology of the graft and renal blood flow were assessed, and the indices of pulsatility, resistance and acceleration were measured. Four patients required graft explanation: three due to massive hemorrhagic infarction and one due to venous thrombosis. Vascular complications were detected in five transplants (21.7%), urological complications in four (17.4%) and medical complications in two (8.7%). The most common vascular complication was unilateral renal artery stenosis. Color Doppler ultrasound diagnosed all the medical and urological complications and three of the five cases of vascular pathology (60%). Renal size was seen to be increased during the first postoperative year. The ultrasonographic study is more difficult to perform in en bloc kidney transplantation than in single kidney grafting: however, given its marked sensitivity in the detection of postransplantation complications. Doppler ultrasound is the imaging technique of choice in the determination of the cause of deteriorated kidney function. (Author) 15 refs

    We have analyzed ultrasonographic findings of 55 cases of hydronephrosis and 34 cases of renal masses. The results are as follows: 1. 55 cases of hydronephrosis revealed renal enlargement in 55 cases, separation of central echo complex in 27 cases, multiple anechoic areas radiating from the center in 25 cases and dilated renal pelvis in 24 cases. 2. Among the masses in 34 cases, simple renal cyst were 15 cases, polycystic kidney in 8 cases, hypernephroma in 8 cases, Wilm's tumor in 2 cases and agiomyolipoma in 1 case. 3. Simple renal cyst revealed single in 14 cases (93%) and well defined anechoic mass with posterior enhancement in all cases. 4. Polycystic kidney revealed bilateral irregular shaped renal enlargement and multiple anechoic cysts throughout the kidney. 2 cases (25%) involved liver. 5. 6 cases (75%) of hypernephroma revealed ill defined moderately echogenic mass without posterior enhancement. 6. All cases of Wilm's tumor revealed well defined large mixed echogenic mass in right kidney. 7. Angiomyolipoma revealed bilateral dense echogenic mass with large hemorrhage cyst in right kidney. 8. The ultrasonography is useful noninvasive diagnostic modality of evaluation of renal masses and hydronephrosis.

    The aim of this study is to record the observations and experience on the diagnosis and management of abdominal tuberculosis (TB) and to highlight the difficulties in the diagnosis and management of this condition. Two hundred consecutive patients attending the Gastroenterology Department of the King Khalid National Guard Hospital, Jeddah, Kingdom of Saudi Arabia between May 1991 and May 2001, suspected with abdominal TB were investigated. A detailed clinical history and physical examination were obtained. Data of 75 confirmed cases of abdominal TB were analyzed. The most common presenting symptoms were anorexia (84%), abdominal pain (84%) and weight loss (72%). Abdominal tenderness was the most common clinical finding, followed by ascites and abdominal mass (42%). The chest radiograph suggestive of pulmonary TB was diagnosed in 24 patients (32%). Computed tomographic (CT) scanning revealed abnormalities in all 51 patients who underwent the procedure, while positive findings were observed by abdominal ultrasound in 66% of the tested patients. Histopathological examination of patients showed tuberculosis granuloma, while acid fast bacilli were seen in 34%. Mycobacterium tuberculosis was identified by microbiological methods in 60% of patients. The most common presenting symptoms were anorexia (84%), abdominal pain (84%) and weight loss (72%).

    Myositis ossificans (MO) is a benign soft tissue lesion with non-neoplastic heterotopic bone formation. MO in the intermediate and mature stages can be easily diagnosed if characteristic imaging findings such as a peripheral zonal pattern of ossification with variable thickness is observed. However, it is difficult to correctly diagnose early MO because it can mimic malignancy clinically, radiologically, and histopathologically. We report a case of early pseudosarcomatous phase of non-traumatic MO with atypical imaging findings. A 59-year-old woman presented with pain followed by a mass in the left thigh within a week. MR imaging and ultrasonography showed an intramuscular lesion with preserved muscle fascicles in the vastus lateralis muscle. Intralesional ossification or calcification was not seen on ultrasonography. A diagnosis of myositis ossificans was made by ultrasonographically guided biopsy. (orig.)

    The medical care currently to brown lemurs (Eulemur fulvus) is limited by a lack of knowledge of their anatomy. The aim of this study was to describe the anatomy and histology and obtain ultrasonographic measurements of normal adrenal glands in these animals. The adrenal glands of four lemurs cadavers were used for the anatomical and histological studies, and those of 15 anesthetized lemurs were examined by ultrasonography. Anatomically, the adrenal glands of brown lemurs are comparable to those of other species. The histological findings showed that the cortex is organized into three distinct layers, whereas most domestic mammals have an additional zone. The surface area of the adrenal glands increased with body weight, and the area of the right adrenal was slightly larger than the left. We suggest using ultrasonography to aid the etiological diagnosis of behavioral abnormalities that might be due to dysfunctions of the adrenal gland. © 2017 John Wiley & Sons A/S.

    Dissections due to deceleration trauma are rarely limited to the infradiaphragmal aorta (only 2-3%) and are usually lethal. Here we report the unusual course of an abdominal aortic dissection with aneurysmatic enlargement of the false lumen. Based on diagnostic imaging, a therapeutic stent application was planed in order to close the entry and to prevent rupture. During the intervention sondation of the false lumen revealed that the left renal artery had a reentry. Due to the complexity of the entry - reentry situation of the left renal artery the intervention was not possible, and the patient had to undergo vascular surgery. (orig.) [de

    The authors describe three cases of intraabdominal fibromathosis: two cases with intraperithoneal location and another one with retroperithoneal location. All of them are benign noncapsulated tumours of the fibrous tissue with tendancy to local recurrence. Abdominal fibromathosis may determine any form of acute or chronic digestive manifestations. Only to the accuracy of the histo-pathological examination is due the diagnosis between fibromathosis and fibrosarcoma, reactive fibrosis, mixoma and nodular fasceitis. The surgical excision must not be economical and the association with radiant therapy must also be considered.

    This article discusses abdominal aortic emergencies. There is a common thread of risk factors and causes of these diseases, including age, male gender, hypertension, dyslipidemia, and connective tissue disorders. The most common presenting symptom of these disorders is pain, usually in the chest, flank, abdomen, or back. Computed tomography scan is the gold standard for diagnosis of pathologic conditions of the aorta in the hemodynamically stable patient. Treatment consists of a combination of blood pressure and heart rate control and, in many cases, emergent surgical intervention. Copyright © 2017 Elsevier Inc. All rights reserved.

    A 32-year-old Filipino female, working as an x-ray technician, presented to the Emergency Room (ER) with acute abdominal pain for one day. The pain was mainly on the left side and left hypochondrium. She had recurring abdominal pain before but not significant to worry her. She also complained of abdominal distension, which she noticed one week ago. Abdominal examination revealed fullness in the left hypochondrium with marked tenderness but negative rebound. Abdominal ultrasound (US) showed a huge mass mainly in the left hypochondrium. The origin of the mass cannot be identified by US. A computerized tomography scan showed a mass in the left side of the abdomen crossing the midline with a necrotic centre. The hospital course of the patient runs smoothly, and she was discharged after 7-days and referred to an Oncology Center. Abdominal mesothelioma is a neoplasm arising from the mesothelial surface lining the abdominal cavity. It is less frequent than that of the pleura. It is a rapidly growing and fatal malignancy with a median survival of less than 1-year. The relation between pleural malignant mesothelioma and asbestos is well recognized since it was described in 19602 but implication of asbestos exposure in the etiology of the peritoneal type is less obvious. This patient history is giving no obvious exposure to asbestos but as she is working in the Radiology Department as an x-ray technician she is well exposed to x-ray, but the effect of radioactivity on induction of mesothelioma is still disputed.4 There are several reports linking malignant mesothelioma to radioactivity due to radiation therapy.The fibrous mesothelioma (sarcomatous), as in this case, which is difficult to diagnose microscopically, looks like a fibroma, unless helped by tissue culture. The treatment options of malignant mesothelioma include surgery, intraperitoneal chemotherapy and whole abdominal radiation or multimodality therapy, which were suggested that might prolong the survival in

    Objective: To test the accuracy and reproducibility of ultrasound and computed tomography (CT) for the quantification of abdominal fat in correlation with the anthropometric, clinical, and biochemical assessments. Materials and Methods: Using ultrasound and CT, we determined the thickness of subcutaneous and intra-abdominal fat in 101 subjects-of whom 39 (38.6%) were men and 62 (61.4%) were women-with a mean age of 66.3 years (60-80 years). The ultrasound data were correlated with the anthropometric, clinical, and biochemical parameters, as well as with the areas measured by abdominal CT. Results: Intra-abdominal thickness was the variable for which the correlation with the areas of abdominal fat was strongest (i.e., the correlation coefficient was highest). We also tested the reproducibility of ultrasound and CT for the assessment of abdominal fat and found that CT measurements of abdominal fat showed greater reproducibility, having higher intraobserver and interobserver reliability than had the ultrasound measurements. There was a significant correlation between ultrasound and CT, with a correlation coefficient of 0.71. Conclusion: In the assessment of abdominal fat, the intraobserver and interobserver reliability were greater for CT than for ultrasound, although both methods showed high accuracy and good reproducibility.

    A 25-year-old woman presented with abdominal discomfort and weight loss. Sonography demonstrated a well defined, anechoic, cystic mass with posterior acoustic enhancement, internal thin septations, and a peripheral hypoechoic solid portion that had no increased blood flow on Doppler ultrasound. Contrast-enhanced CT revealed a cystic omental mass with internal thin septations and an enhancing solid portion which appeared as the hypoechoic solid portion on ultrasonography. A pathologic specimen demonstrated a pseudocyst containing serous fluid with gelatinous material. The solid component at the peripheral portion of the pseudocyst indicated caseous necrosis with multinucleated giant cells. This histologic finding was consistent with tuberculosis and supported the final diagnosis of omental pseudocyst caused by tuberculous peritonitis. Therefore, intraperitoneal pseudocyst with tuberculosis should be considered in the differential diagnosis of an intraperitoneal cystic mass in a young adult

    To describe the ultrasonographic findings in liver abscesses after the administration of a second generation agent. To perform the differential diagnosis of liver abscesses with other focal liver lesions. We evaluated 28 liver abscesses in 5 patients before and after the administration of SonoVue. We also evaluated liver lesions in six patients in whom the differential diagnosis with liver abscess was considered in the baseline ultrasonographic examination. A typical enhancement pattern consisting of peripheral ring enhancement in the arterial phase and absence of central enhancement was observed in 21 (75%) abscesses. In another 6 (21.4%) abscesses, arterial enhancement was seen in large areas of the lesion, while other areas showed no uptake. One case (3.6%) had a multiseptated pattern of enhancement. Segmental hepatic enhancement was observed in 6 abscesses. In the liver lesions in which the differential diagnosis with abscess was carried out, 5 of the 6 showed no enhancement in any phase. The other lesion, a cystic metastasis, had irregular peripheral enhancement in the arterial phase. None of these lesions had segmental hepatic enhancement in the arterial phase. Contrast administration improves the performance of ultrasonography in the diagnosis of liver abscesses. There are three patterns of enhancement and these correlate well with the findings at CT and MRI. Contrast-enhanced ultrasonography is very useful for defining the internal architecture of the abscess, which is important for choosing the type of treatment. Contrast-enhanced ultrasonography also enables the differential diagnosis with other focal liver lesions.

    The purpose of this study was to determine the reproducibility of measurements on duplex ultrasonography (DU) and air plethysmography (APG) in subjects with post-thrombotic syndrome. Duplex ultrasonography and APG were used to measure indices of lower limb venous reflux in 15 limbs with a history of deep vein thrombosis and evidence of venous insufficiency as diagnosed by ultrasonography. Three limbs were in class 0; 4 were in classes 1 to 3; and 8 were in classes 4 to 6, according to clinical, etiologic, anatomic, and pathophysiologic clinical classification. Duplex ultrasonography was performed 3 times on the same day, and venous diameter, area, peak reflux velocity, reflux flow volume, and reflux duration measurements were obtained. Air plethysmography was performed on 2 days, 7 to 10 days apart, with 1 measurement on the first day and 2 measurements on the second day. Values obtained from APG included outflow fraction, venous filling index, ejection fraction, and residual volume fraction. The measurements were performed by a vascular technologist blinded to the previous test results. One-way analysis of variance, the Student paired t test, and Bland-Altman plots were used to examine the statistical differences of the DU and APG parameters for all measurements. The mean coefficient of variation for within-subject measurements of all DU and APG parameters measured was less than 10%. Bland-Altman plots showed that there were no apparent trends with increasing values over a wide range for any of the DU parameters, nor were there any for the APG parameters. Under ideal conditions, when measured by a highly trained technologist, both DU and APG showed satisfactory reproducibility.

Serial ultrasonography demonstrated progressive enlargement of the mass and infant was delivered at 33 + 6 weeks gestational age following maternal complications. On the fifth day, at laparotomy, a huge mass connected to the lower portion of the liver was completely resected. Microscopic evaluation confirmed a hepatic mesenchymal hamartoma. Postoperative recovery was uneventful and the infant was discharged at 4 weeks. The antenatal diagnosis of the hepatic mesenchymal hamartoma by fetal MRI and subsequent follow-up by serial ultrasonography emphasizes the importance of combining these 2 modalities for optimal management of the pregnancy to allow a favorable outcome.

    Full Text Available History of present illness: While watering his lawn, a 36-year-old man felt two sharp bites to his bilateral ankles. He reports that he then saw a light brown, 2-foot snake slither away from him. He came to the emergency department because of pain and swelling in his ankles and inability to bear weight. Physical examination revealed bilateral ankle swelling and puncture marks on his left lateral heel and medial right ankle. Palpation, passive flexion and extension elicited severe pain bilaterally. Blood work including prothrombin time (PT, partial thromboplastin time (PTT, international normalized ratio (INR, and fibrinogen were within normal limits. Consultation with Poison Control indicated the snake was likely a copperhead, which is a venomous snake whose bites rarely require antivenin. Significant findings: In this case, ultrasonography of the lateral surface of the left foot revealed soft tissue edema (red arrow and fluid collection (white asterisk adjacent to the extensor tendon (white arrow. The edematous area resembles cobblestones, with hypoechoic areas of fluid spanning relatively hyperechoic fat lobules. The tendon is surrounded by anechoic fluid, expanding the potential space in the sheath. No hyperechoic foreign objects were noted. Discussion: The patient was diagnosed with soft tissue injury and extensor tenosynovitis after a snake envenomation. Snake venom contains metalloproteinases and other enzymatic proteins that cause local tissue edema and necrosis.1 After a snake bite, ultrasound can be used to assess for retained fangs, soft tissue edema, tendon sheath fluid, muscle fasciculation, and injury to deeper musculature that may not be readily apparent on physical exam.2,3 Most patients with tenosynovitis will recover with immobilization of the joint and non-steroidal anti-inflammatory medications.4 Rarely, the tendon may become infected requiring antibiotics and surgical intervention.4 Topics: Ultrasound, snake envenomation

    Full Text Available Background and Aims: Accurate prediction of the Cormack-Lehane (CL grade preoperatively can help in better airway management of the patient during induction of anaesthesia. Our aim was to determine the utility of ultrasonography in predicting CL grade. Methods: We studied 100 patients undergoing general endotracheal anaesthesia. Mallampati (MP class, thyromental distance (TMD and sternomental distance (SMD were noted. Ultrasound measurements of the anterior neck soft tissue thickness at the level of the hyoid (ANS-Hyoid, anterior neck soft tissue thickness at the level of the vocal cords (ANS-VC and ratio of the depth of the pre-epiglottic space (Pre-E to the  distance from the epiglottis to the mid-point of the distance between the vocal cords (E-VC were obtained. CL grade was noted during intubation. Chi-square test was employed to determine if there was any statistical difference in the measurements of patients with different CL grades. Sensitivity, specificity, positive predictive value (PPV, negative predictive value (NPV and accuracy were calculated for the various parameters. Results: The incidence of difficult intubation was 14%. An ANS-VC >0.23 cm had a sensitivity of 85.7% in predicting a CL Grade of 3 or 4, which was higher than that of MP class, TMD and SMD. However, the specificity, PPV and accuracy were lower than the physical parameters. The NPV was comparable. Conclusion: Ultrasound is a useful tool in airway assessment. ANS-VC >0.23 cm is a potential predictor of difficult intubation. ANS-Hyoid is not indicative of difficult intubation. The ratio Pre-E/E-VC has a low to moderate predictive value.

  17. Ultrasonography in Gastroenterology: The Need for Training

    2018-02-01

    Full Text Available The use of ultrasonography (US as an imaging modality in medicine has spread across almost every clinical specialty. This diffusion is based on the simplicity, accessibility, portability and affordability of the technique producing real-time high-resolution images using non-ionising radiation. On the other hand, this trend also extended the technique to settings other than healthcare, such as public facilities, private houses or remote sites. This tendency can be observed worldwide, from developing countries to prestigious medical schools and tertiary referral hospitals. Furthermore, point-of-care US (POCUS, i.e., US executed at the patient’s bedside to obtain real-time objective information with diagnostic and clinical monitoring purposes or to guide invasive procedures, has been incorporated in many specialties. In gastroenterology, despite the essential role of endoscopy, clinical practice is highly dependent on non-endoscopic imaging techniques. However, as in other specialties, the indications of US in gastroenterology have been increasing steadily, covering a broad range of conditions. In response to the generalised employment of US by non-radiologists, institutions such as the European Federation of Societies for Ultrasound in Medicine and Biology and the Royal College of Radiologists issued recommendations to ensure high-quality practice. These theoretical and practical requisites include performing a certain number of examinations and mandatory skills in order to achieve certification to execute unsupervised US. Therefore, there is a need for modern gastroenterology to include US as a basic skill in its clinical practice. To ensure the provision of high-quality US, adequate instruction of future specialists should be guaranteed by the gastroenterology departments and required in the residency training programme.

  18. Is pneumoperitoneum the terra ignota in ultrasonography?

    Full Text Available In most cases, pneumoperitoneum is caused by gastrointestinal perforation, which usually requires surgical treatment. Many authors believe that ultrasound imaging of pneumoperitoneum is at least as effective as conventional radiography, or even that its efficacy is superior. In such a situation, it is imperative to make this modality one of the main tools in the diagnostic arsenal of emergency medicine. This is the main aim of this paper. First, ultrasound anatomy of so-called thoracic-abdominal border is discussed. The equipment requirements emphasize that the diagnostic process can be conducted with the simplest portable US scanner, even without the Doppler mode. The technique of a US examination, the aim of which is to detect, free air in the peritoneal cavity is also simple and conducted with the patients lying down, either in the supine or lateral position. A convex transducer with the frequency of 3.5–5 MHz is applied above the lower intercostal spaces on the right and left side, to the epigastric region below the xiphoid process and in various sites of the abdominal wall. The most effective examination, however, is conducted in the left lateral position via the right intercostal spaces. The differential diagnosis on the right side under the diaphragm should include the presence of a subdiaphragmatic abscess with gas and a hepatic abscess with a similar content as well as transposition of the colon in between the diaphragm and the liver (Chilaiditi syndrome. It seems that the inclusion of a US examination to the E-FAST method in order to detect free gas in the peritoneal cavity is justified since it is a sign of gastrointestinal perforation in numerous cases, and is clinically as relevant as the presence of free fluid.

    Application of chest radiography for all multiple trauma patients is associated with a significant increase in total costs, exposure to radiation, and overcrowding of the emergency department. Ultrasound has been introduced as an alternative diagnostic tool in this regard. The aim of the present study is to compare the diagnostic accuracy of chest ultrasonography and radiography in detection of traumatic intrathoracic injuries. In the present prospective cross-sectional study, patients with traumatic intrathoracic injuries, who were referred to the emergency department from December 2013 to December 2014, were assessed. The patients underwent bedside ultrasound, radiographic and computed tomography (CT) scan examinations based on ATLS recommendations. Screening performance characteristics of ultrasonography and radiography were compared using SPSS 21.0. Chest CT scan was considered as gold standard. 152 chest trauma patients with a mean age of 31.4 ± 13.8 years (range: 4 ‒ 67), were enrolled (77.6% male). Chest CT scan showed pulmonary contusion in 48 (31.6%) patients, hemothorax in 29 (19.1%), and pneumothorax in 55 (36.2%) cases. Area under the ROC curve of ultrasonography in detection of pneumothorax, hemothorax, and pulmonary contusion were 0.91 (95% CI: 0.86‒0.96), 0.86 (95% CI: 0.78‒0.94), and 0.80 (95% CI: 0.736‒0.88), respectively. Area under the ROC curve of radiography was 0.80 (95% CI: 0.736‒0.87) for detection of pneumothorax, 0.77 (95% CI: 0.68‒0.86) for hemothorax, and 0.58 (95% CI: 0.5‒0.67) for pulmonary contusion. Comparison of areas under the ROC curve declared the significant superiority of ultrasonography in detection of pneumothorax (p = 0.02) and pulmonary contusion (p radiography in the initial evaluation of patients with traumatic injuries to the thoracic cavity.

    Breast cancer screening was carried out at our institution in a ''Human Dock'' style health check, by inspection and palpation, together with ultrasonography. Breast cancers detected were reviewed and the utility of ultrasonography was evaluated. A total of 14,063 women underwent the screening and the results were good, with a recall rate of 3.4%, a cancer detection rate of 0.30%, and a positive predictive value of 8.7%. Of 42 breast cancers detected by ultrasonography, 30 (71%) were 1.5 cm or less in diameter. For breast cancers detected by inspection and palpation, the detection rate for small cancers measuring 1.5 cm or less was 33% (10 out of 30 women), and 100% (12 women) for tumors measuring more than 1.5 cm. The cancer detection rate by mammography was 39% (9 out of 23 cancers) for tumors measuring 1.5 cm or less, and 91% (10 out of 11 cases) for those larger than 1.5 cm. Thus cancer detection by ultrasonography was optimal for tumors measuring 1.5 cm or less. Histologically proven lymph node metastasis was positive in 8 (25%) of 32 patients, among whom some had primary cancers measuring 1.5 cm or less. Tumor volume doubling time (TVDT) was measurable in 10 women; there was no change in size in one instance, and in the others TVDT was 4.8 to 32.5 months (mean 15.5 months), small cancers approximately 1 cm in size having a long TVDT. In women whose cancer size could be determined twice or more, TVDT tended to be short when a cancer measured about 1 cm or more. Cancers with a long TVDT showed low histological malignancy, and thus detection of breast cancers with a long TVDT at screening appears to be rewarding. (author)

  1. Comparison between doppler ultrasonography and renal scintigraphy in assessment of post-transplant renal function

    To compare the usefulness of Doppler ultrasonography and renal scintigraphy in the assessment of short- and long-term function of transplanted kidneys. We retrospectively reviewed the cases of 79 patients who underwent Doppler ultrasonography and technetium-99m diethylene triamine pentaacetic acid renal scintigraphy on the same day, within 4 days of renal transplantation. Image parameters were evaluated for statistical differences. There was a strong positive correlation between the glomerular filtration rate (GFR) as measured by renal scintigraphy and the estimated GFR (eGFR) based on serum creatinine levels (correlation coefficient = 0.71). Scan grade according to the time-activity curve, resistive index, and end diastolic velocity showed moderate correlations with the eGFR (correlation coefficients = -0.557, -0.329, and 0.370, respectively) in the early post-transplantation period. The mean survival time was longer in patients with lower resistive indices (≤ 0.68, 54.9 months vs. > 0.68, 29.5 months) and lower pulsatility indices (≤ 1.32, 53.8 months vs. > 1.32, 28.7 months); however, there were no statistically significant differences in the long-term follow-up period (p = 0.121 for resistive index and p = 0.074 for pulsatility index). Renal scintigraphy is a more sensitive method than Doppler ultrasonography for assessing transplanted kidney function in the early post-transplantation period. Doppler ultrasonography might reflect the long-term survival time. However, it is difficult to predict long-term renal function using either method.

    The ring-tailed lemur (Lemur catta) is primarily distributed in south and southwestern Madagascar. It is classified as an endangered species by the International Union for Conservation of Nature. Various abdominal diseases, such as hepatic lipidosis, intestinal ulcers, cystitis, urinary tract obstruction, and neoplasia (e.g., colonic adenocarcinoma and cholangiocarcinoma), have been reported in this species. The aim of this study was to describe the normal radiographic and ultrasonographic abdominal anatomy in captive ring-tailed lemurs to provide guidance for clinical use. Radiography of the abdomen and ultrasonography of the liver, spleen, kidneys, and urinary bladder were performed in 13 and 9 healthy captive ring-tailed lemurs, respectively, during their annual health examinations. Normal radiographic and ultrasonographic reference ranges for abdominal organs were established and ratios were calculated. The majority (12/13) of animals had seven lumbar vertebrae. The sacrum had mainly (12/13) three segments. Abdominal serosal detail was excellent in all animals, and hypaxial muscles were conspicuous in the majority (11/13) of animals. The spleen was frequently (12/13) seen on the ventrodorsal (VD) view and rarely (3/13) on the right lateral (RL) view. The liver was less prominent and well contained within the ribcage. The pylorus was mostly (11/13) located to the right of the midline. The right and left kidneys were visible on the RL and VD views, with the right kidney positioned more cranial and dorsal to the left kidney. On ultrasonography, the kidneys appeared ovoid on transverse and longitudinal views. The medulla was hypoechoic to the renal cortex. The renal cortex was frequently (8/9) isoechoic and rarely (1/9) hyperechoic to the splenic parenchyma. The liver parenchyma was hypoechoic (5/5) to the renal cortex. Knowledge of the normal radiographic and ultrasonographic abdominal anatomy of ring-tailed lemurs may be useful in the diagnosis of diseases and in

    During a 12-month period high-resolution, real-time ultrasonography (US) with graded compression was performed on 268 consecutive patients with clinically suspected acute appendicitis and its complications. US visualization of a fluid-filled, non-compressed appendix or a decompressed, thick-walled appendix was the primary criterion for a diagnosis of acute appendicitis. The sonographic findings were correlated with surgical-pathologic outcome in 92 cases and with the findings of clinical follow-ups in the remainder. US was found to be accurate in the diagnosis of acute appendicitis and its complication with a sensitivity of 93.3%, a specificity of 98.9%, and an accuracy of 97%. The predictive value of a positive test was 97.7%; that of a negative test was 96.7%. There were two false-positive examinations in patients with a thick-walled appendix or periapperdiceal abscess, which were surgically confirmed as appendiceal adenocarcinoma and perforated cecal diverticulitis respectively. There were six false-negative examinations in patients with a sonographically no-visible appendix, which were confirmed surgically as acute appendicitis (n=5) and perforated appendicitis (n=1). Our results show that high-resolution, real-time US is an accurate imaging modality in the diagnosis of acute appendicitis and the evaluation of its complications.

    In this study, we investigated utility of ultrasonography for urinary tract infections of infants. The results of the research is as follows : 1. The number of infants under one year old was 100 out of 122 infants who were diagnosed as a unitary infection. The ratio of males to females was 1.7 : 1. Seventy-seven infants who underwent three kinds of radiologic examinations such as kidney sonography (51%), 99m TC DMSA-scan (42%), and VCUG (22%). 2. In comparison of correlation between kidney sonography and VCUG, the sensitivity of kidney sonography was 82% while the specificity of kidney sonography was 58%. In comparison of correlation between kidney sonography and 99m TC DMSA-scan, the sensitivity of kidney sonography was 66% while the specificity of kidney sonography was 67%. 3. Utility of kidney sonography showed the highest efficiency when we considered pain, discomfort, a sense of shame, psychological stress when infants may undergo at the examination, side-effect of a contrast agent after the examination, and complication of exposure to radiation.

    Transient ischemic attack (TIA) patients are at high vascular risk. We assessed the value of extracranial (ECD) and transcranial (TCD) Doppler and duplex ultrasonography to predict clinical outcome after TIA. 176 consecutive TIA patients admitted to the Stroke Unit were recruited in the study. All patients received diffusion-weighted imaging, standardized ECD and TCD. At a median follow-up of 27 months, new vascular events were recorded. 22 (13.8%) patients experienced an ischemic stroke or TIA, 5 (3.1%) a myocardial infarction or acute coronary syndrome, and 5 (3.1%) underwent arterial revascularization. ECD revealed extracranial ≥ 50% stenosis or occlusions in 34 (19.3%) patients, TCD showed intracranial stenosis in 15 (9.2%) and collateral flow patterns due to extracranial stenosis in 5 (3.1%) cases. Multivariate analysis identified these abnormal ECD and TCD findings as predictors of new cerebral ischemic events (ECD: hazard ratio (HR) 4.30, 95% confidence interval (CI) 1.75 to 10.57, P = 0.01; TCD: HR 4.73, 95% CI 1.86 to 12.04, P = 0.01). Abnormal TCD findings were also predictive of cardiovascular ischemic events (HR 18.51, 95% CI 3.49 to 98.24, P = 0.001). TIA patients with abnormal TCD findings are at high risk to develop further cerebral and cardiovascular ischemic events

    Objective: To assess the final outcome of breast lesions detected during screening ultrasonography (US) and categorized by BI-RADS final assessment. Materials and methods: During a 1-year period, 3817 consecutive asymptomatic women with negative findings at both clinical breast examinations and mammography underwent bilateral whole breast US and BI-RADS categories were provided for US-detected breast lesions. The reference standard was a combination of histology and US follow-up ({>=}12 months), and the final outcomes of 1192 US-detected lesions were analyzed. Results: Of 904 category 2 lesions, 890 remained stable for 12-60 months. Biopsies of 14 lesions revealed no malignancies (NPV = 100%). Of 247 category 3 lesions, 232 remained stable for 12-60 months. Biopsies of 15 lesions revealed 2 malignancies, which were diagnosed within 6 months of the index examination and were node negative (NPV = 99.2%). Of 41 category 4 lesions, biopsies of 38 lesions revealed 5 malignancies (PPV = 12.2%), and 3 remained stable for 37-51 months. No US-detected lesion was classified as category 5. Conclusion: The rates of malignancy for US-detected BI-RADS categories 2, 3, and 4 lesions were 0%, 0.8%, and 12.2%, respectively. The final assessment of US BI-RADS categorization showed it to be an appropriate predictor of malignancy for screening US-detected breast lesions.

    CECT scan is considered essential for selective non-operative management (SNOM) of patients with abdominal trauma. However, CECT has its own hazards and limitations. We evaluated the safety and efficacy of selective non-operative management of patients with abdominal trauma without the mandatory use of CECT scan in a prospective study. Patients with peritonitis and ongoing intra-abdominal bleed were excluded. Consenting FAST positive, hemodynamically stable patients with blunt and penetrating abdominal trauma between 18 and 60 years of age were included and admitted for SNOM and detailed ultrasonography of the abdomen (in all) with or without CECT abdomen (selectively). Eighty-four patients with abdominal trauma were admitted during the study period. Twenty-two patients did not satisfy the inclusion criteria and 18 required immediate laparotomy based on primary survey. Remaining 44 patients were admitted for SNOM: mean ± SD age of these patients was 27 ± 8.7 years; 40 (89 %) were males. Thirty-five patients (79.54 %) sustained blunt trauma (RTI = 16, Fall = 16, others = 3) while nine patients (20.45 %) sustained penetrating trauma. SNOM without CECT was successful in 36 (81.82 %) patients. Five (11.36 %) patients underwent delayed emergency laparotomy based on clinical and detailed USG evaluation. CECT was not done in these patients. Three patients underwent CECT for various reasons; however, they were managed with SNOM. Thus, SNOM without abdominal CECT was successful in 36 (81.82 %) patients. SNOM failed in five patients but abdominal USG was sufficient. SNOM can be practised safely in patients of abdominal trauma with limited use of CECT scan.

    Although the very first attempt to use ultrasound for diagnostic purpose in medicine may be traced back to the 1940's, the modern ultrasound imaging has only been started in 1963 by G. Kossoff, who developed the idea of grayscale ultrasonography together with the automatic waterbath scanner, Octoson, to examine pelvic and other abdominal organs. The signal processing, logarithmic compression of incoming backscattered echo signals, greatly Improved image quality and thus facilitated the use of ultrasound imaging in clinical diagnostic purposes. The bistable, black and white ultrasound equipment were used in the 60's, and even sophisticated B-mode contact scanners had been completely replaced by the real-time B-mode equipment and then the technique started to be used widely in medical imaging in clinical and radiology departments. These rather drastic changes took place since the introduction of the phased array technique introduced by Somer in 1967 and later the linear array method introduced by Bom in 1970. Other rare metabolic diseases have to be analyzed carefully for the differential diagnosis. In summary, ultrasonography is a useful measure to identify the presence of pathologic changes in the liver. The information obtained is mostly of morphological nature, though some additional findings could be obtained by careful analysis of the sonographic features. Examination is quick, non-invasive and findings are fairly reproducible and even very small lesions could be identified. Combined use of the ultrasound imaging with other modalities such as the radio isotope scanning, X ray, CT or MRI will be very helpful in identifying and characterising the lesions in the liver

    The aim of this study was to determine whether hyperechoic fatty tissue (HFT) at transabdominal and transvaginal ultrasonography in women with acute pelvic pain has a diagnostic role. We studied 201 women (mean age, 32 years) with acute pelvic and lower abdominal pain; we performed ultrasonography (US) in all them. Of the 201, 94 with gynecological problems were included., They were divided into two groups: with pelvic inflammatory disease (PID: n = 45) and without PID (n = 49). We evaluated the presence and distribution of HFT and its role in differential diagnosis between PID and non-PID groups. We found, using US, HFT in 36/45 (80%) patients with PID by US. Of the 36, single-center HFT was observed in 12/36 (33.3%) patients and multicentric HFT was detected in 24/36 (66.7%). HFT was present adjacent to inflammatory foci, tuboovarian abscesses or inflamed salpinx in 30 women: HFT was present outside the pelvic cavity in 24. Among the latter 24, HFT was present only in the lower abdomen, and not in the pelvic cavity in 6. In the non-PID group, HFT was found in the lower abdomen and pelvic cavity in 7 women. Four of the seven were misdiagnosed with PID. One of seven women with a hemorrhagic corpus luteal cyst rupture with underlying PID and two with ectopic pregnancy with HFT were correctly diagnosed. The presence of HFT may be a reliable US finding for the diagnosis of PID. HFT distinguishes PID from other acute gynecological problems

    Purpose: To investigate the value of double contrast-enhanced ultrasonography (DCEUS) in the detection of periampullary cancer. Materials and methods: Ninety-nine patients with surgery or biopsy-proven periampullary cancer who underwent both DCEUS and magnetic resonance imaging (MRI) examinations before operation were enrolled in our study. DCEUS in which intravenous microbubbles were used in combination with oral contrast agent and MRI were performed preoperatively to make a detection diagnosis of periampullary cancer. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of DCEUS, B-mode ultrasonography (BUS) and MRI were calculated and compared. Receiver operating characteristic (ROC) curves were used to evaluate the accuracy of BUS, DCEUS and MRI in the detection. Stratified analyses were performed for different pathological types and different sizes of periampullary lesions. The inter- and intra-observer reliability of DCEUS for cancer detection was also investigated. Result: There were no significant differences in sensitivity, specificity, PPV, NPV or accuracy between DCEUS and MRI (all P > 0.05). ROC analysis showed that the accuracy of DCEUS or MRI was higher than that of BUS (P < 0.001), while no significant differences were noted in the accuracy between DCEUS and MR. In the 76 cases of periampullary cancer, DCEUS appeared to be superior to BUS for ampullary carcinoma, duodenum carcinoma and for lesions with an average diameter of less than 3 cm. DCEUS appeared equal to BUS in other groups. No significant differences were noted between DCEUS and MRI in the stratified analysis. A considerably well agreement between DCEUS and MRI was obtained using Kappa analysis (k = 0.649, P < 0.001). The intra- and inter-observer reproducibility were both good for detection of periampullary cancer by DCEUS, with a Kappa values of 0.783 (P < 0.01) and 0.732 (P < 0.01), respectively. Conclusion: DCEUS provides an

    Clinical application of positron emission tomography (PET) is rapidly increasing for the detection and staging of cancer at whole-body studies performed with the glucose analogue tracer 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FG). Although FDG PET cannot match the anatomic resolution of conventional imaging techniques in the liver and the other abdominal organs, it is particularly useful for identification and characterization of the entire body simultaneously. FDG PET can show foci of metastatic disease that may not be apparent at conventional anatomic imaging and can aid in the characterizing of indeterminate soft-tissue masses. Most abdominal cancer requires surgical management. FGD PET can improve the selection of patients for surgical treatment and thereby reduce the morbidity and mortality associated with inappropriate surgery. FDG PET is also useful for the early detection of recurrence and the monitoring of therapeutic effect. The abdominal cancers, such as gastroesophageal cancer, colorectal cancer, liver cancer and pancreatic cancer, are common malignancies in Korea, and PET is one of the most promising and useful methodologies for the management of abdominal cancers

    Full Text Available Perforation of the inflamed diverticula is a common diverticulitis complication. It usually leads to the formation of a local abscess. In some rare cases, the inflammatory process may spread towards extra-abdominal sites like the anterior or posterior abdominal wall or the thigh and form an abscess in these sites. We present the case of a 73-year-old man with a history of pain at the lower left quadrant of the abdomen for 20 days and a visible mass in this site. Ultrasonography and computed tomography revealed this mass to be an abscess of the abdominal wall which had been formed by the spread of ruptured sigmoid diverticulitis by continuity of tissue through the lower left abdominal wall. Local drainage of the abscess was performed and the patient was discharged after alleviation of symptoms and an uneventful course. We also discuss causes of abdominal wall abscesses along with the possible pathways by which an intra-abdominal abscess could spread outside the abdominal cavity.

    Full Text Available Introduction: Application of chest radiography for all multiple trauma patients is associated with a significant increase in total costs, exposure to radiation, and overcrowding of the emergency department. Ultrasound has been introduced as an alternative diagnostic tool in this regard. The aim of the present study is to compare the diagnostic accuracy of chest ultrasonography and radiography in detection of traumatic intrathoracic injuries. Methods: In the present prospective cross-sectional study, patients with traumatic intrathoracic injuries, who were referred to the emergency department from December 2013 to December 2014, were assessed. The patients underwent bedside ultrasound, radiographic and computed tomography (CT scan examinations based on ATLS recommendations. Screening performance characteristics of ultrasonography and radiography were compared using SPSS 21.0. Chest CT scan was considered as gold standard. Results: 152 chest trauma patients with a mean age of 31.4 ± 13.8 years (range: 4 ‒ 67, were enrolled (77.6% male. Chest CT scan showed pulmonary contusion in 48 (31.6% patients, hemothorax in 29 (19.1%, and pneumothorax in 55 (36.2% cases. Area under the ROC curve of ultrasonography in detection of pneumothorax, hemothorax, and pulmonary contusion were 0.91 (95% CI: 0.86‒0.96, 0.86 (95% CI: 0.78‒0.94, and 0.80 (95% CI: 0.736‒0.88, respectively. Area under the ROC curve of radiography was 0.80 (95% CI: 0.736‒0.87 for detection of pneumothorax, 0.77 (95% CI: 0.68‒0.86 for hemothorax, and 0.58 (95% CI: 0.5‒0.67 for pulmonary contusion. Comparison of areas under the ROC curve declared the significant superiority of ultrasonography in detection of pneumothorax (p = 0.02 and pulmonary contusion (p < 0.001. However, the diagnostic value of the two tests was equal in detection of hemothorax (p = 0.08. Conclusion: The results of the present study showed that ultrasonography is preferable to radiography in the initial

    Objective: To evaluate the ultrasonography in the diagnosis and differential diagnosis of gynecologic emergency. Methods: 138 patients suffered from gynecologic emergency were examined with ultrasonography. The images were retrospectively reviewed and compared with pathologic or clinical results. Results: The total correct diagnostic rate was 89.1%. Among 138 cases of gynecologic emergency, there were 45 cases of ectopic pregnancy, 27 cases of ruptured corpus luteum, 24 cases of torsion of ovarian cyst, and 42 cases of acute pelvic inflammation. The correct diagnostic rates were 91.1%, 81.5%, 87.5%, 92.2%, respectively. Conclusion: The ultrasonography plays an important role in the diagnosis of gynecological emergency. When the US findings were not typical, the clinical history, symptoms and HCG level should be considered in order to avoid misdiagnosis. (authors)

    The diagnostic power of combined cholescintigraphy and ultrasonography was tested in 67 patients suspected of having acute cholecystitis; of these, 42 (63%) had acute cholecystitis. The predictive value of a positive scintigraphy (PVpos) was 95% and that of a negative (PVneg) was 91% (n = 67......). The PVpos and PVneg of ultrasonography were 89% and 75%, respectively (n = 54), and these values did not achieve statistical significance when compared with those for scintigraphy. Inconclusive tests were 10% and 11%, respectively, but in no patient were both scintigraphy and ultrasonography inconclusive...... that in patients suspected of having acute cholecystitis cholescintigraphy should be the first diagnostic procedure performed. If the scintigraphy is positive, additional ultrasonographic detection of gallstones makes the diagnosis almost certain. If one diagnostic modality is inconclusive, the other makes a fair...

    A vulvovaginal discharge following parturition in a bitch is often a cause of concern to owners and clinicians, especially if whelping was complicated in any way. Ultrasonography could potentially distinguish between normal and abnormal postpartum uterine states because the uterine wall and luminal contents can be imaged in detail. Five normal bitches were examined to determine the normal ultrasonographic appearance of the postpartum uterus and the sensitivity of ultrasonography in detecting the involuting uterus, comparing this sensitivity with that of radiography. Ultrasonography was done at 1, 4, 8, 12, 18 and 24 days postpartum, radiography at 1, 4, 8, 12 and 18 days postpartum. By 12 days postpartum, the uterus could not be seen on radiographs, while at 24 days postpartum the uterus was still sonographically identifiable. The ultrasonographic characteristics of the involuting uterus are described

Subjects and methods. Forty-three patients with different causes of inadequate GIT function of various origin and ACS (disseminated peritonitis (45%, pancreatitis (24%, and severe concomitant injury (31% were examined. Group 1 (control received complete parenteral nutritional feeding (n=23; APACHE II scores, 21±4; calculated probability of fatal outcome, 33.5%. In Group II (study, complete parenteral feeding in the first 24 hours after stabilization was supplemented with GIT function support with Pepsisorb (Nutricia in doses of 500, 1000, and 1500 ml on days 1, 2, and 3, respectively (n=20; APACHE II scores, 20±6; calculated probability of fatal outcome, 37.1%. During early enteral nutritional support, the SOFA score was significantly less than that in Group 1 on days 2—3; the oxygenation index significantly increased on day 3; the value of intra-abdominal hypertension decreased to the control values. The positive effect of the GIT function support regimen on regression of the multiple organ dysfunction syndrome (MODS was confirmed by the lowered levels of biological markers (von Willebrand factor (WF and endothelin-1 as markers of endothelial damage of MODS. Correlation analysis showed a direct correlation between the markers of endothelial damage and the SOFA scores (r=0.34; p=0.05 for WF and r=0.49;p=0.03 for endothelin. Conclusion. The GIT function support regimen via early enteral alimentation with Peptisorb, which was initiated in the first 24 hours after admission, is able to level off the manifestations of the early stages of the abdominal compartment syndrome, with the acceptable values of oxygen balance and water-electrolyte and osmotic homeostasis being achieved.

    Widespread use of fetal ultrasonography is accompanied by more frequent detection of antenatal hydronephrosis. Therefore, sonographic evaluation of neonates with a history of antenatal hydronephrosis is becoming more widespread. As an initial postnatal non-invasive imaging modality, ultrasonography is used to screen for persistence of hydronephrosis, determine the level and severity of obstruction, and contribute to appropriate diagnosis and treatment. This review aims to provide a practical overview of the sonographic evaluation of neonatal hydronephrosis and to describe the sonographic findings of conditions associated with hydronephrosis in the newborn.

Over a 2-year period, 35 patients with azoospermia underwent an infertility workup, which included transrectal ultrasonography. Sonograms of 10 of the 35 patients were normal; 8 patients had enlarged seminal vesicles containing cysts, 6 had ejaculatory duct dilation, 5 had seminal vesicle calcification, 3 had seminal vesicle atrophy-hypoplasia and 3 patients had midline prostatic cysts. Transrectal sonography is a useful modality to evaluate seminal duct abnormalities, some of which may cause azoospermia. (author)

    Experience in the field of musculoskeletal diseases and advanced technology of medical sonographers allow increasing accuracy in US investigations of most lesions of both hip and knee superficial tendons. In this field, US is more and more widely replacing other imaging modalities, including MR imaging. Ultrasonography may now be used also for articular diseases purpose, including joint effusion, synovitis, intraarticular loose bodies, ligamentous injuries, articular cysts, as well as for certain osseous lesions like stress or insufficiency fractures of superficial bones. However, ultrasonography has still to be evaluated for these latter indications.

    We examined the usefulness and image quality of a mobile miniaturised ultrasound scanner in a medical ward. The instrument (SonoSite 180), weighing 2.4 kg, is a hand-carried system powered by batteries. In 25 days we recruited consecutively 36 patients aged 23-92. Four different operators evaluated the use of the scanner. We examined one group of patients with relatively simple diagnostic challenges (e.g. gallbladder stone) and one group of patients demanding more advanced visualisation (e.g. peptic ulcer, colitis). The scanner was easy to carry around and scanning was initiated in 10 seconds. We found satisfactory image quality on 81% of the examinations, despite the fact that in 28% of cases, bowel air and abdominal fat impaired acoustic penetration. Average scanning time was 7 +/- 3 minutes. In 83% of cases, mobile scanning adequately solved the clinical problem. Diagnostic work-up or treatment was changed because of scanning in 39% of the patients. In 64% of cases, standard-procedure referral to the department of radiology was avoided. In 81% of the examinations the operator was very satisfied with the scanner, also in cases that required advanced visualisation. This mobile scanner was simple to use and gave quick results in a medical ward. The operators were very satisfied: mobile scanning changed diagnostic work-up or treatment in 4 out of 10 cases. Mobile ultrasound scanning enables early diagnosis and seems to promote an efficient flow of patients in a hospital unit.

    The objectives of the current study were as follows: 1) to evaluate blood flow in the uterine (UA) and umbilical (Uma) arteries in pregnant capuchin monkeys by measuring the resistive index (RI) and pulsatility index (PI); 2) to determine the presence or absence of the early diastolic notch and diastolic flow in the UA and Uma flow waveforms, respectively; 3) to perform conceptus echobiometry for fetal growth assessment during pregnancy; 4) to describe the moment that the fetal organs were initially observed; and 5) to determine when the diagnosis of fetal gender is possible. Seven healthy, sexually mature female Sapajus apella were examined in Weeks -20 to -1 before whelping (whelping Week 0). Triplex Doppler was used to assess the blood flow and fetal heart rate, and B-mode ultrasonography was used to assess the fetal organs and conceptus measurements, including the gestational sac latero-lateral longitudinal (LLL) and latero-lateral transversal (LLT), the crown rump length (CRL), biparietal diameter (BPD), occipito-frontal diameter (OFD), head circumference (HC), abdominal circumference (AC), femur length (FL) and fetal organ. All the pregnancies ended with a normal whelping and the birth of a live newborn. Prior to whelping, all conceptus dimensions increased significantly, whereas the RI and PI of both the UA and Uma decreased significantly. For the UA, the RI and PI were (mean ± SEM) 0.835 ± 0.017 and 2.157 ± 0.129, 0.808 ± 0.008 and 1.920 ± 0.041, and 0.761 ± 0.006 and 1.759 ± 0.036 on periods -3, -2 and -1, respectively. For the Uma, the RI and PI were 0.97 ± 0.01 and 2.50 ± 0.02 at Week -17 and were 0.64 ± 0.02 and 0.98 ± 0.04 at Week -1, respectively.

    To analyze the high-frequency ultrasound image features of acute scrotum in children and explore the value of high-frequency ultrasonography in the diagnosis and differential diagnosis of the disease. This retrospective study included 256 children aged 2 days to 14 years undergoing color Doppler ultrasonography at 2 hours to 3 days after onset of acute scrotum. We analyzed the morphology, internal echo and blood supply of the testis in comparison with the clinical and pathological results. Among the 256 cases, acute testicular torsion was found in 23, of which 16 were treated by complete resection the necrotic testis and the other 7 by surgical reduction of testicular torsion. Ultrasonographically, the involved testes presented different degrees of increase or decrease in volume, with uneven internal echoes, irregular hypoechoic flakes, and testicular hydrocele. Color Doppler flow imaging (CDFI) showed significant blood flow signals around the diseased testes but none within them. Acute testicular appendix torsion was found in 116 cases, in which ultrasonography manifested nodules with round or oval abnormal echoes between the upper pole of the testis and caput epididymidis, first hypoechoic and then gradually increased, heterogeneous internally. CDFI revealed enlarged epididymides and enriched testicular blood flow but no blood flow signals in the nodules. The 103 cases of acute epididymitis were ultrasonographically characterized by varied degrees of swelling of the involved epididymis with uneven internal echoes and rich blood flow signals on CDFI. Six of the cases were diagnosed as acute orchitis, with the ultrasonographic features of testicular swelling and low but uniform internal echoes, with rich blood flow signals on CDFI. Incarcerated inguinal hernia was confirmed in 15 cases, in which ultrasonography revealed intrusion of the hernia into the obviously enlarged scrotal sac with the mesentery and intestine in it, and blood flow visible on CDFI.

    The aim of the present study was to characterize the dynamic changes of the testes and the pelvic genitalia in vivo in male dromedary. Eighty-one clinically healthy male dromedaries aged 1.5 to 12 years were assigned for the present study. Testicular length, breadth, and depth as well as epididymal head and tail were measured using caliper and ultrasonography. The pelvic genitalia, including bulbourethral gland, prostate, and pelvic urethra were examined using ultrasonography. The results revealed that the three dimensions of the testes and epididymal tail and head showed significant increase with age (P caliper and those by ultrasonography between groups, but the correlation was highly significant (P < 0.01) for the total number of the examined animals. There were significant and steady increases of the size of bulbourethral gland in all examined groups (P < 0.01). Pars disseminata of the prostate gland and pelvic urethra were significantly higher in sexually mature compared with prepubertal groups (P < 0.01). It was concluded that ultrasonography is a useful tool in studying the developmental changes of the testes and accessory glands of the male dromedary. The obtained data could provide a reference values for predicting camel puberty and future fertility. Copyright © 2012 Elsevier Inc. All rights reserved.

    Since there are no reliable investigative tools for imaging parastomal hernia, new techniques are needed. The aim of this study was to assess the validity of intrastomal three-dimensional ultrasonography (3D) as an alternative to CT scanning for the assessment of stomal complaints. Twenty patients with stomal complaints, indicating surgery, were examined preoperatively with a CT scan in the supine position and 3D intrastomal ultrasonography in the supine and erect positions. Comparison with findings at surgery, considered to be the true state, was made. Both imaging methods, 3D ultrasonography and CT scanning, showed high sensitivity (ultrasound 15/18, CT scan 15/18) and specificity (ultrasound 2/2, CT scan 1/2) when judged by a dedicated radiologist. Corresponding values for interpretation of CT scans in routine clinical practice was for sensitivity 17/18 and for specificity 1/2. 3D ultrasonography has a high validity and is a promising alternative to CT scanning in the supine position to distinguish a bulge from a parastomal hernia.

    The development of ultrasonography allowed for skin imaging used in dermatology and esthetic medicine. By means of classic and high-frequency ultrasonographies, changes within the dermis and subcutaneous tissue can be presented. The aim of this study was to show the possibilities of applying classic and high-frequency ultrasonographies in esthetic dermatology based on monitoring various types of anti-cellulite therapies. Sixty-one women with cellulite were assigned to two smaller groups. One group was using anti-cellulite cream and the second group was a placebo group. The ultrasound examination was carried out before the initiation and after the completion of the treatment and evaluated epidermal echoes, the thickness of the subcutaneous tissue and the dermis, dermis echogenicity, the length and surface area of the subcutaneous tissue fascicles growing into the dermis, and the presence or absence of edemas. After the completion of the treatment, a statistically significant difference was observed. The most useful parameters were as follows: the thickness of the subcutaneous tissue, echogenicity, the surface area and length of the subcutaneous tissue, as well as the presence of edemas. The discussed changes were not observed in the placebo group. Classic and high-frequency ultrasonographies are useful methods for monitoring anti-cellulite therapies. © 2011 John Wiley & Sons A/S.

    Full Text Available The aim of this study was to evaluate the diagnostic value of high-frequency ultrasonography in detecting atrophy of foot muscles in Chinese patients of type 2 diabetes mellitus (T2DM. Chinese patients of T2DM with (n=56 or without (n=50 diabetic peripheral neuropathy (DPN and the control subjects (n=50 were enrolled. The nondominant foot of all subjects was examined with high-frequency ultrasonography. The transverse diameter, thickness, and cross-sectional area of the extensor digitorum brevis muscle (EDB and the thickness of the muscles of the first interstitium (MILs were measured. The results showed that the ultrasonographic transverse diameter, thickness, and cross-sectional area of EDB and the thickness of MILs in patients of T2DM with DPN were significantly smaller than those in patients of T2DM without DPN (all P<0.01 and those in the control subjects (all P<0.01. The transverse diameter and cross-sectional area of the EDB and thickness of MILs in patients of T2DM without DPN were significantly smaller than those of the control subjects (all P<0.01. In conclusion, the atrophy of foot muscle in Chinese T2DM patients can be detected by high-frequency ultrasonography. Notably, ultrasonography may detect early atrophy of foot muscles in patients without DPN.

  19. Economics of abdominal wall reconstruction.

    2013-10-01

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

    Primary hepatic carcinosarcoma is a rare tumor and is comprised of a mixture of carcinomatous and sarcomatous elements. We present a case of primary carcinosarcoma of the liver in a 59-year-old woman, which was confirmed by pathology following surgical resection. Using contrast-enhanced ultrasonography, the tumor showed peripheral nodular hyperenhancement in the arterial phase with two feeding arterial vessels and a large internal non-enhancing portion in the center. The peripheral nodular portion of the tumor showed hypoenhancement in the later phase.

    Introduction: Liver biopsy, although a gold standard in diagnosis of nonalcoholic fatty liver disease (NAFLD), is an invasive and expensive tool. Aim: To assess the diagnostic accuracy of abdominal ultrasound in detecting NAFLD among a group of overweight/obese children having one or more liver abnormality (clinical hepatomegaly, raised ALT or echogenic liver parenchyma by ultrasound). Methods: Seventy-eight overweight/obese children were referred to the Pediatric Hepatology Unit, Cairo University Pediatric Hospital, Egypt, for assessment for hepatic abnormalities. Out of the 78 children, 34 had one or more abnormality in the form of clinical hepatomegaly, raised alanine aminotransferase (ALT) and/or echogenic liver parenchyma by ultrasound. All 34 cases underwent liver biopsy for evaluation for NAFLD. Results: Histological NAFLD was detected in 15 cases; 8 simple steatosis and 7 nonalcoholic steatohepatitis (NASH). Sonographic evaluation of hepatic parenchymal echogenicity revealed: 11 with grade 1 echogenicity, 12 with grade 2 and 9 with grade 3 while only 2 had normal liver echopattern. Ultrasonography was 100% sensitive and 100% specific in detecting histological NAFLD, while the positive predictive value (PPV) was 47% and negative predictive value (NPV) was 11%. After consolidating the included children into 2 groups: the first including normal and grade 1 echogenicity and the second including grades 2 and 3, the sensitivity of ultrasonography in detecting histological NAFLD was still 100%, while negative predictive value increased to 100% with an accuracy of 82%. Conclusion: We conclude that ultrasonography is an important non invasive tool in assessment for NAFLD. Normal or grade 1 hepatic echogenicity can soundly exclude histological NAFLD and obviates the need for liver biopsy.

    A 79-year-old woman presented to a private medical practice 2 years previously for an elective ultrasound screening scan. This imaging provided the evidence for a diagnosis of an abdominal aortic aneurysm (AAA) to be made. Despite having a number of recognised risk factors for an AAA, her general practitioner at the time did not follow the guidance set out by the private medical professional, that is, to refer the patient to a vascular specialist to be entered into a surveillance programme and surgically evaluated. The patient became symptomatic with her AAA, was admitted to hospital and found to have a tender, symptomatic, 6 cm leaking AAA. She consented for an emergency open AAA repair within a few hours of being admitted to hospital, despite the 50% perioperative mortality risk. The patient spent 4 days in intensive care where she recovered well. She was discharged after a 12 day hospital stay but unfortunately passed away shortly after her discharge from a previously undiagnosed gastric cancer. 2014 BMJ Publishing Group Ltd.

    Gastric tubes are commonly used for the administration of drugs and tube feeding for people who are unable to swallow. Feeding via a tube misplaced in the trachea can result in severe pneumonia. Therefore, the confirmation of tube placement in the stomach after tube insertion is important. Recent studies have reported that ultrasonography provides good diagnostic accuracy estimates in the confirmation of appropriate tube placement. Hence, ultrasound could provide a promising alternative to X-rays in the confirmation of tube placement, especially in settings where X-ray facilities are unavailable or difficult to access. To assess the diagnostic accuracy of ultrasound for gastric tube placement confirmation. We searched the Cochrane Library (2016, Issue 3), MEDLINE (to March 2016), Embase (to March 2016), National Institute for Health Research (NIHR) PROSPERO Register (to May 2016), Aggressive Research Intelligence Facility Databases (to May 2016), ClinicalTrials.gov (to May 2016), ISRCTN registry (May 2016), World Health Organization International Clinical Trials Registry Platform (to May 2016) and reference lists of articles, and contacted study authors. We included studies that evaluated the diagnostic accuracy of naso- and orogastric tube placement confirmed by ultrasound visualization using X-ray visualization as the reference standard. We included cross-sectional studies, and case-control studies. We excluded case series or case reports. Studies were excluded if X-ray visualization was not the reference standard or if the tube being placed was a gastrostomy or enteric tube. Two review authors independently assessed the risk of bias and extracted data from each of the included studies. We contacted authors of the included studies to obtain missing data. We identified 10 studies (545 participants and 560 tube insertions) which met our inclusion criteria.No study was assigned low risk of bias or low concern in every QUADAS-2 domain.

    AIM: To compare computed tomography enteroclysis (CTE) vs small intestine contrast ultrasonography (SICUS) for assessing small bowel lesions in Crohn's disease (CD), when using surgical pathology as gold standard. METHODS: From January 2007 to July 2008, 15 eligible patients undergoing elective resection of the distal ileum and coecum (or right colon) were prospectively enrolled. All patients were under follow-up. The study population included 6 males and 9 females, with a median age of 44 years (range: 18-80 years). Inclusion criteria: (1) certain diagnosis of small bowel requiring elective ileo-colonic resection; (2) age between 18-80 years; (3) elective surgery in our Surgical Unit; and (4) written informed consent. SICUS and CTE were performed ≤ 3 mo before surgery, followed by surgical pathology. The following small bowel lesions were blindly reported by one sonologist, radiologist, surgeon and histolopathologist: disease site, extent, strictures, abscesses, fistulae, small bowel dilation. Comparison between findings at SICUS, CTE, surgical specimens and histological examination was made by assessing the specificity, sensitivity and accuracy of each technique, when using surgical findings as gold standard. RESULTS: Among the 15 patients enrolled, CTE was not feasible in 2 patients, due to urgent surgery in one patients and to low compliance in the second patient, refusing to perform CTE due to the discomfort related to the naso-jejunal tube. The analysis for comparing CTE vs SICUS findings was therefore performed in 13 out of the 15 CD patients enrolled. Differently from CTE, SICUS was feasible in all the 15 patients enrolled. No complications were observed when using SICUS or CTE. Surgical pathology findings in the tested population included: small bowel stricture in 13 patients, small bowel dilation above ileal stricture in 10 patients, abdominal abscesses in 2 patients, enteric fistulae in 5 patients, lymphnodes enlargement (> 1 cm) in 7 patients and

  7. Abdominal expiratory muscle activity in anesthetized vagotomized neonatal rats.

    The pattern of respiratory activity in abdominal muscles was studied in anesthetized, spontaneously breathing, vagotomized neonatal rats at postnatal days 0-3. Anesthesia (2.0% isoflurane, 50% O(2)) depressed breathing and resulted in hypercapnia. Under this condition, abdominal muscles showed discharge late in the expiratory phase (E2 activity) in most rats. As the depth of anesthesia decreased, the amplitude of discharges in the diaphragm and abdominal muscles increased. A small additional burst frequently occurred in abdominal muscles just after the termination of diaphragmatic inspiratory activity (E1 or postinspiratory activity). Since this E1 activity is not often observed in adult rats, the abdominal respiratory pattern likely changes during postnatal development. Anoxia-induced gasping after periodic expiratory activity without inspiratory activity, and in most rats, abdominal expiratory activity disappeared before terminal apnea. These results suggest that a biphasic abdominal motor pattern (a combination of E2 and E1 activity) is a characteristic of vagotomized neonatal rats during normal respiration.

    Full Text Available Abdominal pregnancy appears once in 3000 pregnancies. It usually terminates with abortion and urgent surgery. Thanks to ultrasonography and computed tomography the diagnosis is possible before surgery. Most frequently the diagnosis has been established during emergency laparotomy. Gynaecologists are not in agreement wheather removal of placenta is mandatory or not, as it may include removal of parts or entire organs or may be followed with serious bleeding difficult to control. We present a 21-year old woman in whom during an urgent laparotomy performed for abdominal pregnancy placenta inserted in the spleen was left in situ. Postoperatively the patient developed subphrenic abscess which could not be solved without reoperation during which both the placenta and the spleen were removed. Ten years after surgery she is symptom-free.

    Background/Aims Endoscopic retrograde cholangiopancreatography (ERCP) is the initial therapy recommended for patients with high likelihood of choledocholithiasis. To determine whether endoscopic ultrasonography (EUS) can prevent diagnostic ERCPs in patients with high probability of choledocholithiasis and inconclusive ultrasonography (US). Methods All patients with high likelihood of choledocholithiasis and negative US underwent EUS. ERCP was performed for the patients who showed a definite stone/sludge on EUS. Patients without choledocholithiasis were followed up for 3 months. The primary outcome was avoidance of diagnostic ERCP. Results We included 78 patients (51 women; 27 men). Of these, 25 and 7 (total 41%) were diagnosed with choledocholithiasis and sludge, respectively; stone/sludge was removed in 96.9% of the patients. EUS ruled out choledocholithiasis in 38 patients (48.7%). Two of them were found to have choledocholithiasis on follow-up. The sensitivity, specificity, positive and negative predictive value of EUS for detecting choledocholithiasis were 93.9%, 97.3%, 96.9%, and 94.7%, respectively. Unnecessary ERCP was avoided in 57.7% of the patients by using the EUS-first approach. Conclusions EUS is a highly accurate and safe procedure. EUS can replace ERCP as the initial investigation in patients with a high probability of choledocholithiasis. It avoids unnecessary ERCP; hence, decreasing related costs and complications.

    Resident's case problem. Abdominal pain is a common symptom, but not a common diagnosis, of patients referred to physical therapists for examination and intervention. For patients with primary symptoms of abdominal pain, a thorough evaluation must be performed to determine if symptoms are musculoskeletal in nature or of a nonmusculoskeletal origin that would warrant a referral to a different healthcare provider. This report describes the management of 3 adults with primary complaints of abdominal pain who were referred for physical therapy evaluation and treatment. Two of the patients had secondary symptoms of hip and/or low back pain and had previously undergone extensive medical testing for their chronic abdominal pain, without a definitive diagnosis having been determined. A physical therapy evaluation was conducted, and treatment, including manual physical therapy and exercise, was administered to address all relative impairments, once the physical therapist had determined that the patients' symptoms were of musculoskeletal origin. The third patient included in this series was referred to a physical therapist with a diagnosis of greater trochanteric versus iliopsoas bursitis. However, the patient had abdominal pain that was more acute in nature and a history and physical examination findings that were concerning for abdominal pain of nonmusculoskeletal origin. Both patients with abdominal pain of musculoskeletal origin showed marked improvement in pain and disability after 7 treatment sessions. The third patient was referred to her primary care physician, and ultrasound examination of the abdomen revealed several intrauterine masses that were consistent with uterine fibroids. Following uterine fibroid embolization, the patient was symptom free. Although not routinely managed by physical therapists, abdominal pain is a relatively common patient symptom that can have several causes, both musculoskeletal and nonmusculoskeletal. This paper emphasizes the importance

    Full Text Available Abstract Objective: To estimate the prevalence and evaluate sonographic findings compatible with changes consistent with hepatic steatosis in patients referred for abdominal ultrasonography at four reference centers in Aracaju, SE, Brazil. Materials and Methods: Prospective, descriptive survey, with analytical and quantitative approach, comprising abdominal ultrasonography scans performed with a convex, dynamic 3.75 MHz transducer. Liver dimensions and parenchymal echotexture were evaluated, classifying hepatic steatosis into grades (1, 2 or 3. The SPSS® 22.0 software was used for statistical analysis, adopting p < 0.05 as significance level. Results: A total of 800 individuals (561 women and 239 men were evaluated. The prevalence of steatosis was 29.1%, and the male patients were most affected, presenting with more advanced grades of disease (p = 0.021, as follows: 119 grade 1 (51.0%; 94 grade 2 (40.4%; and 20 grade 3 (8.6%. The median age patients' was 46 years. Conclusion: In the present study sample, the prevalence of hepatic steatosis was high, particularly in the male patients. Ultrasonography is suggested as a first choice for the diagnosis of this condition, considering its wide availability, low cost and absence of side effects or risks to the patient.

    Abdominal fat, and in particular, visceral adipose tissue (VAT), is the critical fat depot associated with metabolic aberrations. At present, VAT can only be accurately measured by computed tomography or magnetic resonance imaging (MRI). This study was designed to compare a new abdominal bioelectrical impedance (BIA) device against total abdominal adipose tissue (TAAT) and VAT area measurements made from an abdominal MRI scan, and to assess its reliability and accuracy. One-hundred twenty participants were recruited, stratified by gender and BMI. Participants had triplicate measures of abdominal fat and waist circumference (WC) with the AB-140 (Tanita, Tokyo, Japan) and WC measurements using a manual tape measure. A single abdominal MRI scan was performed as the reference method. Triplicate measures with the AB-140 showed excellent precision for "visceral fat level," trunk fat %, and WC. AB-140 "visceral fat level" showed significantly stronger correlations with MRI TAAT area than with MRI VAT area (r = 0.94 vs. 0.65 in men and 0.92 vs. 0.64 in women). AB-140 WC showed good correlation with manual WC measurements (r = 0.95 in men and 0.90 in women). AB-140 and manual WCs showed comparable correlations with MRI TAAT area (r = 0.92 and 0.96 in men and 0.88 and 0.88 in women). AB-140 is a simple, quick, and precise technique to measure abdominal fat and WC in healthy adults. It provides a useful proxy for TAAT measured by MRI, comparable to the correlation obtained with manual WC measurements. Neither the AB-140 abdominal fat measures nor WC measurement appear to provide a useful proxy measure of VAT.

    In this study, we aimed to investigate the impact of non-alcoholic hepatic steatosis on the liver volume. As investigating hepatic steatosis, we utilized computed tomography (CT) to determine the degree of steatosis and we utilized hepatobiliary ultrasonography (USG) for densitometry and correlation. As hepatosteatosis group, 35 patients over 18 years of age and whose abdominal CT scans were requested by several clinics and performed routinely were included in this study, and as control group, 40 healthy subjects without hepatosteatosis (clinically and radiologically) and correlated with hepatosteatosis group in terms of age and gender were included in this study. CT densitometry and liver attenuation index (LAI) of all individuals who participated in our study were calculated, and contrast images of patients were transferred to CT-Volume Software (Siemens Syngo Multimodality Workplace; Version VE52A). In this study, interactive and automated volume measurement techniques were used together. The volumes were measured separately in patient and control group. In this study for each stage in USG, there was found a direct correlation in terms of LAI and volume, and this correlation was statistically significant (p liver disease, and there is a positive linear correlation between the liver size and volume, and liver volume increases in the non-alcoholic fatty liver disease.

    When endoscopic retrograde cholangiopancreatography (ERCP) fails to decompress the biliary system or the pancreatic duct, endoscopic ultrasonography (EUS)-guided biliary or pancreatic access and drainage can be used. Data show a high success rate and acceptable adverse event rate for EUS-guided biliary drainage. The outcomes of EUS-guided biliary drainage seem equivalent to percutaneous drainage and ERCP, whereas only retrospective studies are available for pancreatic duct drainage. In this article, revision of the technical and clinical status and the current evidence of interventional EUS-guided biliary and pancreatic duct access and drainage are presented.

    Full Text Available A 37-year-old female patient with chronic and stubborn abdominal pain had been hospitalized five times in three Western hospitals, but no effects were observed. No abnormalities were found in blood tests, gastrointestinal endoscopy, sonogram, and computed tomography of the abdomen, except mild paralytic ileus. The patient decided to rely on Korean medicine as an inpatient. She was diagnosed with functional abdominal pain syndrome, and her symptom differentiation was the “Yang deficiency of spleen and kidney.” A herbal drug, Hwangikyeji-tang, along with moxibustion and acupuncture, was given to the patient. Abdominal pain and related symptoms were reduced radically within 16 days of treatment. This report shows a therapeutic potential of Korean medicine-based treatment for functional abdominal pain syndrome.

    Full Text Available Abstract Cardiac angiosarcomas are extremely rare in childhood, they are rapidly progressive tumours that often present themselves as diagnostic dilemmas, resulting in delayed diagnosis. Also, extracardiac manifestations, including abdominal pain, are extremely rare in patients with intracardiac tumors. We herein present the case of a 15-year-old girl who presented with abdominal pain. Echocardiography and thoracic computed tomography showed right atrial mass. The patient underwent surgery, chemotherapy, and radiotherapy. Eight months after treatment, abdominal recurrence was detected. The abdominal mass was resected, and radiotherapy and new chemotherapy protocol were given. The present case illustrates a rare case of primary cardiac angiosarcoma posing a diagnostic dilemma in an adolescent girl.

    2016-01-01

    Traumatic abdominal wall hernia is a rare but serious diagnosis resulting from blunt abdominal trauma. The clinical diagnosis is not usually straightforward and the hernia is often discovered at the time of the surgical exploration for intra-abdominal injuries or by imaging studies. A 25-year-old obese, restraint, male patient was the victim of a high-speed road traffic accident. Among other injuries, he showed extensive skin maceration and bruising over the lower abdomen and flanks upon presentation, however he did not need any surgical intervention. Contrast-enhanced computed tomography scan of the abdomen and pelvis demonstrated extensive abdominal wall muscular disruption over both flanks with herniation of the right colon. Counselled to follow up in 4-6 weeks to have the hernia surgically repaired, he showed up after 8 months with a large muscular defect resulting in a large hernia containing small and large bowel loops. The timing and type of the surgical repair of traumatic abdominal wall hernia depends upon the size of the hernia defect and the presence of associated intra-abdominal injuries. Delayed repair; however, may result in a large defect making primary, non-prosthetic repair impossible and increases the risk of abdominal compartment syndrome after surgical correction. Traumatic abdominal wall hernia presents a diagnostic as well as a therapeutic challenge. The therapeutic approach is governed by a multitude of factors emphasizing the need of a patient-tailored, case by case management plan. Copyright © 2016 The Author(s). Published by Elsevier Ltd..

    This pilot study aimed to assess the feasibility, acceptance and costs of an ultrasound scan screening programme for abdominal aortic aneurysms (AAA) in the elderly male population resident in Canton Ticino, Switzerland. The target population were male patients aged 65-80 years who attended the outpatient clinics of the Lugano Regional Hospital in 2013. The patients showing interest were contacted by phone to verify their eligibility and fix the appointment for the ultrasound scan of the abdominal aorta. Patients with recent examinations suitable for AAA detection were excluded. Aneurysm was defined as an abdominal aorta with sagittal and/or axial diameter  30 mm. Patients' characteristics and study results were presented as descriptive statistics. The chi-squared test was used to compare categorical variables with p rate was 68.3%. A previously unknown AAA was diagnosed in 31 patients (4.2%, 95% confidence interval 2.8-5.9%). Age and area of residence had a statistically significant impact on patient's acceptance rate (p <0.05). The mean cost per screened patient was CHF 88. AAA screening of male patients aged 65-80 years is feasible with limited financial and organisational effort. Adherence might be improved by a larger community-based programme and involvement of general practitioners.

    To assess ultrasonography's capabilities in the detection of cancer and other diseases, abdominal ultrasonographic screening was performed for 3,707 Hiroshima and 2,294 Nagasaki atomic bomb survivors and comparison subjects who participated in the Adult Health Study from 1 November 1981 to 31 October 1985 in Hiroshima and from 1 August 1984 to 31 July 1986 in Nagasaki. A total of 20 cancers was detected, consisting of 7 hepatomas, 3 gastric cancers, 3 renal cancers, 2 cancers of the urinary bladder, and 1 cancer each of the ovary, pancreas, colon, ureter and liver (metastatic). The cancer detection rate was 0.33 %. The diagnoses of seven cancer subjects in each city were subsequently confirmed at autopsy or surgery; diagnoses of four cancer subjects in Hiroshima and two in Nagasaki were obtained from death certificates. Among the 20 cancer patients, 13 were asymptomatic. After the ultrasonographic detection and diagnosis of these 20 cancers, the medical records of each of the 20 cancer patients were reviewed for any evidence of cancer detection by other examining techniques, and the records of only 3 patients revealed such recent detection. The tumor and tissue registries were similarly checked, but no evidence of earlier diagnosis of their disease was found. Ten of the cancer patients had received ionizing radiation doses from the A-bombs ranging up to 3,421 mGy (DS86), but no correlation was established between cancer prevalence and the A-bomb doses. A variety of tumors, 259 in number and most probably benign, were also detected with ultrasonography. In addition, numerous other abnormalities were diagnosed, with prevalences of 7.7 % for cholelithiasis, 5.7 % for renal cysts, and 3.8 % for liver cysts. No statistical analysis was performed concerning the prevalence of the diseases detected. (author)

    Nonspecific clinical presentations often lead to misdiagnosis of focal cysticercal myositis. This report emphasizes the role of ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of solitary intramuscular cysticercosis. Six patients with persistent post-traumatic isolated muscular swelling were treated with analgesic and antibiotics, but the swelling did not subside. Radiographs showed soft tissue swelling with no bony abnormalities. Laboratory markers were inconclusive. Ultrasonographic and magnetic resonance images (MRI) showed typical features of intramuscular cysticercosis. Clinical, radiological, and fundoscopic evaluation of brain and eyes could not isolate any cysticercosis focus in these organs. Patients were treated with 3 weeks albendazole therapy. The identifying sonographic features of intramuscular cysticercosis, as evident from this case series, included an intramuscular elliptical or oval anechoic lesion with echogenic intralesional focus likely to be scolex. Magnetic resonance images showed orientation of the cyst along the direction of muscle fibers with T2W hyperintense signal and post-contrast perilesional enhancement. All patients responded to medical treatment. Cysticercosis may manifest as isolated muscular swelling without neurological or ocular involvement. Clinicians should be aware of this clinical condition to avoid misdiagnosis. Ultrasonography and magnetic resonance imaging are good diagnostic aids to establish soft tissue cysticercosis. (orig.)

    This study evaluated the structural changes in the reproductive tract of Asiatic black bears using serial transrectal ultrasonography. In addition, the ultrasonographic observations were compared with the results of vaginal cytology and hormonal analyses. The collection of blood for hormonal analysis, vaginal cytology and transrectal ultrasonography was performed in two bears (Bears 1 and 2) from June 2011 to August 2013 without mating and in a third bear (Bear 3) from April to December 2012, allowing natural mating. Serial ultrasonographic observations showed cyclic changes in ovarian structures (e.g. emergence of small follicles, growth and ovulation of dominant follicles and corpus luteum (CL) formation) during the reproductive cycles of the three bears. The diameter of the uterine horns remained similar throughout the reproductive cycle in Bears 1 and 2, and it remained similar from April until October, but an enlargement containing foetuses was observed in Bear 3 in December. The ultrasonographic observations were consistent with the data obtained through vaginal cytology and progesterone analysis during the reproductive cycle. An average of 4.0 (±0.4) dominant follicles was observed during the oestrous stage (May-August), during which the superficial cells accounted for >90% of the total vaginal cells. In addition, the detection of an average of 2.6 (±0.2) CL was associated with increased plasma progesterone concentrations (3.0 ± 0.4 ng/ml) between June and December (near hibernation). In conclusion, serial transrectal ultrasonography demonstrated yearly oestrous (ovulation) cycles via follicular dynamics and CL formation on ovaries, accordingly with vaginal cytology and hormonal level in the Asiatic black bear. © 2014 Blackwell Verlag GmbH.

    To evaluate the effectiveness of perineal ultrasonography in the evaluation of female stress incontinence after surgical management. Perineal ultrasonography was performed in 19 patients who were surgically treated for stress incontinence and this was performed in erect position. Nineteen patients were divided into two groups, group A for 11 patients with resolved incontinent after surgery and group B for 8 patients with persistent incontinence even after surgery. Using a sagittal scan of the anterior pelvis at the level of the symphysis pubis, the posterior urethrovesical angel (PUVA) and descent of the bladder neck were measured at rest and during stress (Valsalva maneuver), and these measured values obtained before and after surgery were compared between two groups, group A and B. Postoperative PUVA and descent of the bladder neck were decreased when compared with preoperative values measured at rest and during stress in both groups. There was a statistically significant difference in the postoperative PUVA between two groups (p< 0.05). The mean increment of PUVA during stress after surgery was 6.3 ± 3.8. deg in group A and 14.6 ± 6.4. deg in group B, respectively, showing statistically significant difference (p< 0.05). There was also a statistically difference in the mean descent of the bladder neck during stress after surgery between the two groups (p<0.05). The measurement and comparison of PUVA and descent of the bladder neck by perineal ultrasonography before and after surgery in patients with stress incontinence offered useful and objective information in evaluating the effectiveness of surgical management in females stress incontinence, the stress effectiveness in the stress incontinence.

    Although the number of elective operations for abdominal aortic aneurysms (AAA) is increasing, the sex- and age-standardised mortality rate of AAAs continues to rise, especially among men aged 65 years or more. The lethality of ruptured AAA continues to be 80-95%, compared with 5-7% by elective surgery of symptomfree AAA. In order to fulfil all WHO, European, and Danish criteria for screening, a randomised hospitalbased screening trial of 12,639 65-73 year old men in Viborg County (Denmark) was initiated in 1994. It seemed that US screening is a valid, suitable and acceptable method of screening. The acceptance rate was 77%, and 95% accept control scans. Furthermore, persons at the highest risk of having an AAA attend screening more frequently. We found that 97% of the interval cases developed from aortas that initially measured 2.5-2.9 cm - i.e. approx. only 5% attenders need re-screening at 5-year intervals. Two large RCTs have given clear indications of operation. Survivors of surgery enjoy the same quality of life as the background population, and only 2-5% of patients refuse an offer of surgery. Early detection seems relevant since the cardiovascular mortality is more than 4 times higher in AAA patients without previous hospital discharge diagnoses due to cardiovascular disease than among similar men without AAA. The absolute risk difference after 5 years was 16%. So, they will benefit from general cardiovascular preventive action as smoking cessation, statins and low-dose aspirin, which could inhibit further AAA progression. All 4 existing RCTs point in the same direction, viz. in favour of screening of men aged 65 and above. We found that screening significantly reduced AAA-related mortality by 67% within the first five years (NNT = 352). Restriction of screening to men with previous cardiovascular or pulmonary hospital discharge diagnoses would request only 27% of the relevant male population study to be invited, but would only have prevented 46.7% of the

A second issue addressed was whether translocation correlates with anatomic damage to the mucosa. The radiated group (1100 cGy) which received anesthesia also was compared with a control group and a third group which received anesthesia alone but no abdominal radiation. Abdominal radiation lead to 100% positive cultures of MLN between 12 hr and 4 days postradiation. Bacterial translocation was almost nonexistent in the control and anesthesia group. Signs of inflammation and ulceration of the intestinal mucosa were not seen until Day 3 postradiation. Mucosal damage was maximal by Day 4. Bacterial translocation onto the MLN after a single dose of abdominal radiation was not apparently dependent on anatomical, histologic damage of the mucosa

    Full Text Available Introduction. We present a case of a sports injury. The initial presentation and clinical examination belied serious intra-abdominal injuries. Case Presentation. A 16-year-old male patient came to emergency department after a sports-related blunt abdominal injury. Though on clinical examination the injury did not seem to be serious, FAST revealed an obscured splenorenal window. The CT scan revealed a large left renal laceration and a splenic laceration that were managed with Cook coil embolization. Patient remained tachycardic though and had to undergo splenectomy, left nephrectomy, and a repair of left diaphragmatic rent. Patient had no complication and had normal renal function at 6-month followup. Conclusion. The case report indicates that management of blunt intra-abdominal injury is complicated and there is a role for minimally invasive procedures in management of certain patients. A great deal of caution is required in monitoring these patients, and surgical intervention is inevitable in deteriorating patients.

    Full Text Available INTRODUCTION Renal artery aneurysms is relatively uncommon with reported incidence ranges from 0.3% to 1%. However, considering all visceral artery aneurysms the percentage of renal artery aneurysms is relatively high between 15-25%. The distal forms of renal artery aneurysms sometimes require "ex vivo" reconstruction and kidney autotransplantation. CASE REPORT A 75-year-old male presented with the right abdominal and back pain. He suffered from a long history of arterial hypertension and chronic renal failure over the last few months (urea blood = 19.8 mmol/l; creatinine = 198 mmol/l. Duplex ultrasonography showed abdominal aortic aneurysm. Subsequent translumbarangiography revealed juxtarenal abdominal aortic aneurysm associated with distal right renal artery aneurysm. The operation was performed under combined thoracic epidural analgesia and general anesthesia using transperitoneal approach. After the laparotomy, the ascending colon was mobilized and reflected medially followed by Kocher maneuver. The result was visualization of the anterior aspect of the right kidney, the collecting system, ureter as well as the right renal vein and artery with large saccular aneurysm located distally. After mobilization of the renal vessels and careful dissection of the ureter, the kidney was explanted. The operation was continued by two surgical teams. The first team performed abdominal aortic aneurysm resection and reconstruction with bifurcated Dacron graft. The second team performed ex vivo reparation of renal artery aneurysm. All time during the explantation, the kidney was perfused by Collins' solution. The saccular right renal artery aneurysm 4 cm in diameter was located at the kidney hilus at the first bifurcation. Three branches originated from the aneurysm. The aneurysm was resected completely. The longest and widest of three branches arising from the aneurysmal sac was end-to-end anastomized with 6 mm PTFE graft. After this intervention, one of

    Full Text Available Central venous catheters (CVCs are frequently used in neonatal care. The rate of complications upon CVC use is high and the spectrum ranges from catheter tip dislocation to cardiac tamponade and death. Here we present an explanation model to the phenomenon of paravasate into human anatomical cavities based on two illustrative cases: Extremely low birth weight twins suffering from abdominal compartment syndromes due to different pathologies – one with a trans-peritoneal and one with intra-abdominal effusion. In both siblings the peripherally introduced central catheter (PICC perforated the vessel without clinical signs of bleeding and contributed to abdominal and thoracal complications. Case I (23 + 5 gestational week; 770 g; female showed clinical signs of an abdominal compartment syndrome without respective intestinal pathology upon open surgical procedure with ileostomy. Radiographic contrast examination showed retroperitoneal leakage when administered through the catheter. Replacement into the subclavian vein led to cardio-respiratory misbalance due to severe pleural effusion. Re-replacement finally led to clinical restitution after 60 days of intensive care. Case II (23 + 5 gestational week; 690 g; female showed clinical signs of an abdominal compartment syndrome, too. Radiographic contrast examination showed leakage from the PICC into the abdomen. Replacement of the PICC and invasive care led to improvement after 3 days. The 2 cases reveal that the displacement of a PICC can occur without direct clinical signs of hemodynamic imbalance i.e. bleeding or hematoma. Displacement of the catheter tip from intra-vascular, retro-peritoneal position can cause abdominal compartment syndromes either via trans-peritoneal migration of fluids or after perforation of the peritoneum via intra-abdominal administration of given infusion. Both options caused life threatening complications. Watchfulness and intensive surgical and non-surgical care are

    The aim of this study was to (1) generate quantitative CT (QCT) densitometric data based on routine abdominal multi-detector (MDCT) examinations and (2) investigate whether these data can be used to differentiate osteoporotic from healthy females. Twenty-five female patients (group A) with a history of radiotherapy were examined both with routine abdominal MDCT and standard QCT to generate a MDCT-to-QCT conversion equation. Twenty-one osteoporotic (group B) and 23 healthy female patients (group C) were also recruited in the study. Patients of groups B and C underwent routine abdominal MDCT examination for various clinical indications. Mean bone mineral density (BMD) in patients of group A was 103.4 mg/ml {+-} 32.8 with routine abdominal MDCT and 91.0 mg/ml {+-}28.5 with QCT. Quantitative CT BMD{sub QCT} values for patients in groups B and C were calculated utilizing the BMD{sub MDCT} values derived from routine abdominal MDCT data sets and the MDCT to QCT conversion equation: BMD{sub QCT}=0.78. BMD{sub MDCT}+10.13. The calculated QCT densitometric data adequately differentiated osteoporotic from healthy females (area under ROC curve 0.828, p=0.05). In conclusion, this study showed that in a group of female patients, QCT data derived from routine abdominal MDCT examinations discriminated osteoporotic from healthy subjects. (orig.)

    The purpose of this study was to determine and compare interactions between the abdominal musculature and intra-abdominal pressure (IAP) during controlled dynamic and static trunk muscle loading. Myoelectric activity was recorded in six subjects from the rectus abdominis, obliquus externus, obliquus internus, transversus abdominis and erector spinae muscles using surface and intra-muscular fine-wire electrodes. The IAP was recorded intra-gastrically. Trunk flexions and extensions were performed lying on one side on a swivel table. An adjustable brake provided different friction loading conditions, while adding weights to an unbraked swivel table afforded various levels of inertial loading. During trunk extensions at all friction loads, IAP was elevated (1.8-7.2 kPa) with concomitant activity in transversus abdominis and obliquus internus muscles--little or no activity was seen from rectus abdominis and obliquus externus muscles. For inertia loading during trunk extension, IAP levels were somewhat lower (1.8-5.6 kPa) and displayed a second peak when abdominal muscle activity occurred in the course of decelerating the movement. For single trunk flexions with friction loading, IAP was higher than that seen in extension conditions and increased with added resistance. For inertial loading during trunk flexion, IAP showed two peaks, the larger first peak matched peak forward acceleration and general abdominal muscle activation, while the second corresponded to peak deceleration and was accompanied by activity in transversus abdominis and erector spinae muscles. It was apparent that different loading strategies produced markedly different patterns of response in both trunk musculature and intra-abdominal pressure.

    There has been no reported change of ultrasonographic findings of nucleus pulposus in chemonucleolysis. We have found that the particle of herniated nucleus pulposus are highly echogenic and change to low echogenic after chemonucleolysis. On an in vitro experimental study, ultrasonography of the surgical specimen of the herniated nucleus pulposus was highly echogenic. After soaking the chymopapain into the surgical specimen of the herniated nucleus pulposus, the echogenicity was progressively lowered as time passed from 3 minutes to 12 hours. Our preliminary results are divided as two folds; 1. High echogenic shadows of outside of annulus fibrosus on ultrasonography of herniated lumbar disc will be important indicator of selection of patients for good therapeutic results of chemonucleolysis. 2. Progressively lowered echogenicity of high echogenic shadow after chemouncleolysis suggests good reaction of chymopapain with herniated nucleus pulposus.

    The purpose is to determine whether a reversed sequence of bile flow (i.e. small bowel followed by gallbladder) could serve as an indicator of chronic cholecystitis. 43 hepatobiliary scans were reviewed retrospectively with attention to the relative order of gallbladder and small bowel appearance during the first hour. Usually radioactive bile flows initially into the gallbladder followed by passage into the small bowel. The scintigraphic findings were correlated with results from gallbladder histopathology and gallbladder ultrasonography in 11 patients. The specificity of a reversed sequence for chronic cholecystitis was 82% using ultrasonography and 100% for histopathology. The visualization of gallbladder after the small bowel appears in patients referred for possible biliary tract disease predicts chronic cholecystitis (author)

    Transrectal ultrasonography (TRUS) has been widely accepted as a popular imaging modality for Epub ahead of print evaluating the lower rectum, anal sphincters, and pelvic floor in patients with various anorectal diseases. It provides excellent visualization of the layers of the rectal wall and of the anatomy of the anal canal. TRUS is an accurate tool for the staging of primary rectal cancer, especially for early stages. Although magnetic resonance imaging is a modality complementary to TRUS with advantages for evaluating the mesorectum, external sphincter, and deep pelvic inflammation, three-dimensional ultrasonography improves the detection and characterization of perianal fistulas and therefore plays a crucial role in optimal treatment planning. The operator should be familiar with the anatomy of the rectum and pelvic structures relevant to the preoperative evaluation of rectal cancer and other anal canal diseases, and should have technical proficiency in the use of TRUS combined with an awareness of its limitations compared to magnetic resonance imaging.

    Twenty harpy eagles ( Harpia harpyja ) without systemic or ocular diseases were examined to measure blood velocity parameters of the pectinis oculi artery using Doppler ultrasonography. Pectinate artery resistive index (RI) and pulsatility index (PI) were investigated using ocular Doppler ultrasonography. The mean RI and PI values across all eyes were 0.44±0.10 and 0.62±0.20 respectively. Low RI and PI values found in the harpy eagle´s pectinis oculi artery compared with the American pekin ducks one and other tissue suggest indeed a high metabolic activity in pecten oculi and corroborates the hypothesis of a nutritional function and/or intraocular pressure regulation.

    Full Text Available Technologically advanced materials, such as alloys of aluminum, nickel or titanium are currently used increasingly often in significantly loaded components utilized in the aviation industry, among others in the construction of jet turbine engine blades. The article presents a method for diagnosing the condition of the inside of cast blades with the use of laser ultrasonography. The inspection is based on finding hidden flaws with a size of between 10 and 30μm. Laser ultrasonography offers a number of improvements over the non-destructive methods used so far, e.g. the possibility to diagnose the cast on a selected depth, high signal-to-noise ratio and good sensitivity. The article includes a brief overview of non-destructive inspection methods used in foundry engineering and sample results of inspecting the inner structure of a turbo jet engine blade using the method described in the article.

  20. Torsion of abdominal appendages presenting with acute abdominal pain

    Diseases of abnormal appendages are rare causes of abdominal pain in all age groups. Nine patients with torsion and infraction of abdominal appendages were retrospectively reviewed. Four patients had torsion and infarction of the appendices epiploicae, four patients had torsion and infarction of the falciform ligament. The patient with falciform ligament disease represents the first reported case of primary torsion and infarction of the falciform ligament, and the patient with the transverse colon epiplocia represents the first reported case of vibration-induced appendix epiplocia torsion and infarction. The patient with the falciform ligament disease presented with a tender upper abdominal mass and the remaining patients were operated upon with the preoperative diagnosis of acute appendicitis. The presence of normal appendix with free serosanguinous fluid in the peritoneal cavity should raise the possibility of a disease and calls for further evaluation of the intra-abdominal organs. If the diagnosis is suspected preoperatively, CT scan and ultrasound may lead to a correct diagnosis and possibly conservative management. Laparoscopy is playing an increasing diagnostic and therapeutic role in such situations. (author)
