  2. Abdominal ultrasound in AIDS patients

    Escribano, J.; Gonzalez, J.; Alvarez, M.; Rivero, S.; Raya, J.L.; Ruza, M.

    1998-01-01

    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.

  5. Ultrasound tissue Doppler imaging reveals no delay in abdominal muscle feed-forward activity during rapid arm movements in patients with chronic low back pain.

    Cross-sectional study. Comparison of the timing of onset of lateral abdominal muscle activity during rapid arm movements in patients with nonspecific chronic low back pain (cLBP) and back-pain-free controls. Rapid movements of the arm are normally associated with prior activation of trunk-stabilizing muscles in readiness for the impending postural perturbation. Using invasive intramuscular electromyography techniques, studies have shown that this feed-forward function is delayed in some patients with low back pain (LBP). Ultrasound tissue Doppler imaging (TDI) provides an ultrasound method for quantifying muscle activation in a noninvasive manner, allowing investigation of larger groups of patients and controls. Ninety-six individuals participated (48 patients with cLBP and 48 matched LBP-free controls). During rapid shoulder flexion, abduction, and extension, surface electromyographic signals from the deltoid and motion-mode TDI images from the contralateral lateral abdominal muscles were recorded simultaneously. The onset of muscle activity was given by changes in the tissue velocity of the abdominal muscles, as measured with TDI. Pain and disability in the patients were assessed using standardized questionnaires. Data were analyzed using repeated measures analysis of variance. In both groups, feed-forward activity of the lateral abdominal muscles was recorded during arm movements in all directions. The main effect of "group membership" revealed no significant difference between the groups for the earliest onset of abdominal muscle activity (P = 0.398). However, a significant "group x body side" interaction (P = 0.015) was observed, and this was the result of earlier onsets in the cLBP group than controls for the abdominal muscles on the right (but not left) body side. No relationship was found between the time of onset of the earliest abdominal muscle activity and pain intensity, pain frequency, pain medication usage, or Roland Morris disability scores. Patients

    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

  7. Rehabilitative ultrasound imaging of the abdominal muscles.

    Science.gov (United States)

    Teyhen, Deydre S; Gill, Norman W; Whittaker, Jackie L; Henry, Sharon M; Hides, Julie A; Hodges, Paul

    2007-08-01

    Rehabilitative ultrasound imaging (RUSI) of the abdominal muscles is increasingly being used in the management of conditions involving musculoskeletal dysfunctions associated with the abdominal muscles, including certain types of low back and pelvic pain. This commentary provides an overview of current concepts and evidence related to RUSI of the abdominal musculature, including issues addressing the potential role of ultrasound imaging in the assessment and training of these muscles. Both quantitative and qualitative aspects associated with clinical and research applications are considered, as are the possible limitations related to the interpretation of measurements made with RUSI. Research to date has utilized a range of methodological approaches, including different transducer placements and imaging techniques. The pros and cons of the various methods are discussed, and guidelines for future investigations are presented. Potential implications and opportunities for clinical use of RUSI to enhance evidence-based practice are outlined, as are suggestions for future research to further clarify the possible role of RUSI in the evaluation and treatment of abdominal muscular morphology and function.

  8. Plain abdominal film and abdominal ultrasound in intestine occlusion

    International Nuclear Information System (INIS)

    Amodio, C.; Antico, E.; Montesi, A.; Zaccarelli, A.

    1991-01-01

    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

    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.

    AIM: The technical performance of abdominal ultrasound in the investigation of acute abdominal pain has been thoroughly investigated but its therapeutic effects are less well understood. We aimed to determine the therapeutic effect of abdominal ultrasound in the investigation of acute abdominal pain. MATERIAL AND METHODS: A pre- and post-intervention observational study design was used to determine the diagnostic and therapeutic effects of abdominal ultrasound for acute abdominal pain. Referring clinicians completed a pre-ultrasound questionnaire that detailed their leading diagnosis, confidence in this and intended management in 100 consecutive adult patients. Following ultrasound a second questionnaire was completed. This again detailed the leading diagnosis, confidence in this and their intended management. Clinicians quantified the management contribution of ultrasound both for the individual case in question and in their clinical experience generally. RESULTS: The leading diagnosis was either confirmed or rejected in 72 patients and a new diagnosis provided where no prior differential diagnosis existed in 10. Diagnostic confidence increased significantly following ultrasound (mean score 6·5 pre-ultrasound vs 7·6 post-ultrasound, P < 0·001). Intended management changed following ultrasound in 22 patients; 15 intended laparotomies were halted and a further seven patients underwent surgery where this was not originally intended. Ultrasound was rated either 'very' or 'moderately' helpful in 87% of patients, with 99% of clinicians finding it either 'very' or 'moderately' helpful generally. CONCLUSION: Abdominal ultrasound has considerable diagnostic and therapeutic effect in the setting of acute abdominal pain. Dhillon, S. et al. (2002)

    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.

    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.

    The pregnant abdominal trauma patient presents a unique diagnostic challenge. This study aimed to evaluate the accuracy of abdominal sonography for the detection of clinically important injuries in pregnant abdominal trauma patients. A retrospective review was performed of a trauma center database from 2001 to 2011. Medical records were reviewed to determine initial abdominal imaging test results and clinical course. Sensitivity, specificity, positive predictive value, and negative predictive value of ultrasound for detection of traumatic injury were calculated. Of 19,128 patients with suspected abdominal trauma, 385 (2 %) were pregnant. Of these, 372 (97 %) received ultrasound as the initial abdominal imaging test. All 13 pregnant patients who did not receive ultrasound received abdominal CT. Seven pregnant patients underwent both ultrasound and CT. Seven ultrasound examinations were positive, leading to one therapeutic Cesarean section and one laparotomy. One ultrasound was considered false positive (no injury was seen on subsequent CT). There were 365 negative ultrasound examinations. Of these, 364 were true negative (no abdominal injury subsequently found). One ultrasound was considered false negative (a large fetal subchorionic hemorrhage seen on subsequent dedicated obstetrical ultrasound). Sensitivity and positive predictive value were 85.7 %. Specificity and negative predictive value were 99.7 %. Abdominal sonography is an effective and sufficient imaging examination in pregnant abdominal trauma patients. When performed as part of the initial assessment using an abbreviated trauma protocol with brief modifications for pregnancy, ultrasound minimizes diagnostic delay, obviates radiation risk, and provides high sensitivity for injury in the pregnant population.

    Full Text Available ABSTRACT Objective: to verify the efficiency and usefulness of basic ultrasound training in trauma (FAST - Focused Assessment with Sonography in Trauma for emergency physicians in the primary evaluation of abdominal trauma. Methods: a longitudinal and observational study was carried out from 2015 to 2017, with 11 emergency physicians from Hospital Universitário do Oeste do Paraná, submitted to ultrasound training in emergency and trauma (USET® - SBAIT. FAST results started to be collected two months after the course. These were compared with a composite score of complementary exams and surgical findings. Information was stored in a Microsoft Excel program database and submitted to statistical analysis. Results: FAST was performed in 120 patients. In the study, 38.4% of the assessed patients had a shock index ≥0.9. The composite score detected 40 patients with free peritoneal fluid, whereas FAST detected 27 cases. The method sensitivity was 67.5%, specificity was 98.7%, the positive predictive value was 96.4%, the negative predictive value was 85.39% and accuracy was 88%. All those with a positive FAST had a shock index ≥0.9. Fifteen patients with positive FAST and signs of instability were immediately submitted to surgery. Conclusions: the basic training of emergency physicians in FAST showed efficiency and usefulness in abdominal trauma assessment. Due to its low cost and easy implementation, this modality should be considered as a screening strategy for patients with abdominal trauma in health systems.

    We sought to investigate acceptable compression ratios of lossy wavelet compression on 640 x 480 x 8 abdominal ultrasound (US) images. We acquired 100 abdominal US images with normal and abnormal findings from the view station of a 932-bed teaching hospital. The US images were then compressed at quality factors (QFs) of 3, 10, 30, and 50 followed outcomes of a pilot study. This was equal to the average compression ratios of 4.3:1, 8.5:1, 20:1 and 36.6:1, respectively. Four objective measurements were carried out to examine and compare the image degradation between original and compressed images. Receiver operating characteristic (ROC) analysis was also introduced for subjective assessment. Five experienced and qualified radiologists as reviewers blinded to corresponding pathological findings, analysed paired 400 randomly ordered images with two 17-inch thin film transistor/liquid crystal display (TFT/LCD) monitors. At ROC analysis, the average area under curve (Az) for US abdominal image was 0.874 at the ratio of 36.6:1. The compressed image size was only 2.7% for US original at this ratio. The objective parameters showed the higher the mean squared error (MSE) or root mean squared error (RMSE) values, the poorer the image quality. The higher signal-to-noise ratio (SNR) or peak signal-to-noise ratio (PSNR) values indicated better image quality. The average RMSE, PSNR at 36.6:1 for US were 4.84 ± 0.14, 35.45 dB, respectively. This finding suggests that, on the basis of the patient sample, wavelet compression of abdominal US to a ratio of 36.6:1 did not adversely affect diagnostic performance or evaluation error for radiologists' interpretation so as to risk affecting diagnosis

  2. Contemporary Applications of Ultrasound in Abdominal Aortic Aneurysm Management

    Full Text Available Ultrasound (US is a well-established screening tool for detection of abdominal aortic aneurysms (AAA and is currently recommended not only for those with a relevant family history but for all men and high-risk women older than 65 years of age. The advent of minimally invasive endovascular techniques in the treatment of AAAs (EVAR has increased the need for repeat imaging especially in the post-operative period. Nevertheless, preoperative planning, intraoperative execution and postoperative surveillance all mandate accurate imaging. While CTA and angiography have dominated the field, repeatedly exposing patients to the deleterious effects of cumulative radiation and intravenous nephrotoxic contrast, ultrasound technology has significantly evolved over the past decade. In addition to standard color duplex US, 2D, 3D or 4D contrast enhanced US modalities are revolutionizing AAA management and postoperative surveillance. This technology can accurately measure AAA diameter and volume and most importantly it can detect endoleaks post EVAR with high sensitivity and specificity. 4D contrast enhanced US can even provide hemodynamic information about the branch vessels following fenestrated EVARs. The need for experienced US operators and accredited vascular labs is mandatory to guarantee the reliability of the results. This review article presents a comprehensive overview of the literature on the state-of-art US imaging in AAA management, including post EVAR follow-up, techniques and diagnostic accuracy.

  3. Value of ultrasound in the evaluation of blunt abdominal trauma

    Trauma is a major cause of morbidity and mortality in an age group including from teenagers to young adults, in a male dominant proportion, resulting in great economic and social impact. Within the complex of trauma, blunt abdominal trauma (BAT) is frequent event and presents difficulty in the evaluation and management since the clinical examination shows low sensitivity and specificity. The detection of hemo peritoneum is one of the methods of evaluation of possible indirect intra-abdominal injuries, initially using direct diagnostic abdominal paracentesis and posteriorly the diagnostic peritoneal lavage, that despite the effectiveness, have drawbacks such as invasiveness and the inability of hemo peritoneum quantification and the lesion staging, resulting in non-therapeutic laparotomies. Imaging methods provide useful information in the investigation of abdominal injuries, such as conventional and contrast radiology, ultrasound (US) and computed tomography (CT), which is the best effective method, but has its own drawbacks, such as cost, accessibility, use of ionizing radiation and contrast media and the displacement of the patient to the machine. US presents itself as an alternative in the initial evaluation of these patients as noninvasive method, with lack of harmfulness, low cost, fast answer and portability. Nevertheless, this method also has its limitations, as in cases of abdominal injuries without free fluid. This study was conducted in order to establish the performance of the US in this setting, allowing to rationalise the use of CT. For this purpose we studied 163 patients treated in the ER of HC/FMUSP, with the completion of consecutive US and CT. The population fits the usual profile of trauma victims, with 83% male, 56% in the age group between 20 and 39 years and in 73% of cases victims of traffic accidents. They were brought to the service in an average time of 51 minutes, mainly stable and with satisfactory level of consciousness. US took on

    To investigate the association between the size of the hepatic hemangioma and the shape and thickness of the echogenic rim of hepatic hemangioma on abdominal ultrasound. We examined 47 cases (M:F=24:23, mean age 47.1) of hepatic hemangiomas with echogenic rim on abdominal ultrasound during the past 2 years. Radiologic findings were retrospectively reviewed in terms of completeness and thickness of echogenic rim. If echogenic rim showed even thickness, it was measured. But if not, the maximum and minimum thickness of the rim was measured. The association between the size of hemangioma and the completeness and thickness of the echogenic rim were analyzed statistically. Of the 47 cases, complete echogenic rim and incomplete echogenic rim were obtained in 29 (62%) and 18 (38%) cases, respectively. Twenty-two cases of hemangioma were less than 2 cm in diameter, and their distribution according to echogenic rim were as follows: complete echogenic rim (17/20, 91% mean thickness 2.2 cm) and uneven thickness with complete echogenic rim (3/20, 15%, range:2.0-6.1 mm). Twenty-five hemangiomas were larger than 2 cm in diameter and their distribution according to echogenic rim were as follows: complete echogenic rim (n=9, 34%), incomplete echogenic rim (n=16, 64%0,even thickness with complete echogenic rim (3/9, 33%, mean thickness 2.2 mm) and uneven thickness with complete echogenic rim (6/9,67%, range: 2.0-7.6 mm). In statistical analysis, hemangiomas more than 2 cm in diameter were more likely to have incomplete echogenic rim (p<0.05) than those of less than 2 cm; hemangiomas more than with more than 2 cm in diameter and complete echogenic rim showed uneven thickness of echogenic rim (p<0.05), more often than those of less than 2 cm diameter. Hemangiomas with more than 2 cm in diameter showed more frequent incomplete echogenic rim than those of less than 2 cm in diameter, which had more frequent complete echogenic rim. Hemangiomas with complete echogenic rim and even rim

    Although aneurysm of the abdominal infra-renal aorta (AAA) meets criteria warranting B mode ultrasound screening, the advantages of mass screening versus selective targeted opportunistic screening remain a subject of debate. In France, the French Society of Vascular Medicine (SFMV) and the Health Authority (HAS) published recommendations for targeted opportunistic screening in 2006 and 2013 respectively. The SFMV held a mainstream communication day on November 21, 2013 in France involving participants from metropolitan France and overseas departments that led to a proposal for free AAA ultrasound screening: the Vesalius operation. Being a consumer operation, the selection criteria were limited to age (men and women between 60 and 75 years); the age limit was lowered to 50 years in case of direct family history of AAA. More than 7000 people (as many women as men) were screened in 83 centers with a 1.70% prevalence of AAA in the age-based target population (3.12% for men, 0.27% for women). The median diameter of detected AAA was 33 mm (range 20 to 74 mm). The prevalence of AAA was 1.7% in this population. Vesalius data are consistent with those of the literature both in terms of prevalence and for cardiovascular risk factors with the important role of smoking. Lessons from Vesalius to take into consideration are: screening is warranted in men 60 years and over, especially smokers, and in female smokers. Screening beyond 75 years should be discussed. Given the importance of screening, the SFMV set up a year of national screening for AAA (Vesalius operation 2014/2015) in order to increase public and physician awareness about AAA detection, therapeutic management, and monitoring. AAA is a serious, common, disease that kills 6000 people each year. The goal of screening is cost-effective reduction in the death toll. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Chest radiography and abdominal ultrasound are two widely used diagnostic imaging techniques in Western societies. However, little is known about the frequency of these examinations and its determinants. The aim of this descriptive study was to provide detailed information on the number of chest radiography and abdominal ultrasound examinations by age, gender, referring physician and ethnicity. We used data of approximately 3,000,000 sick fund insured persons of the Health Insurance Company Agis in The Netherlands from 1999 to 2003. We calculated annual numbers and corresponding 95% confidence intervals for different age, gender and ethnicity categories. The mean age of the population was 38±22 years and 46% were male. Chest radiographs were ordered in 130 per 1000 persons per year and abdominal ultrasound examinations in 39 per 1000 persons per year; these frequencies did not change noticeable over the five-year period. Chest radiography was performed more often in males (156 vs. 109 per 1,000 persons/year in females; p<0.05) and abdominal ultrasound more often in females (43 vs. 34 per 1000 persons/year in males; p<0.05). Frequencies were highest in persons aged 70-79 years. Compared to medical specialists, general practitioners more frequently referred younger patients and females, especially for abdominal ultrasound. Up to the age of 60 years the frequencies of both chest radiography and abdominal ultrasound were higher in Turks and Moroccans compared to other persons. In conclusion, this study showed marked differences in the frequencies of chest radiography and abdominal ultrasound according to age, gender and ethnicity in The Netherlands

Materials and methods: Twenty-one consecutive patients with AWE were treated as outpatients by US-guided HIFU ablation under conscious sedation. The median size of the AWE was 2.4 cm (range 1.0-5.3 cm). An acoustic power of 200-420 W was used, intermittent HIFU exposure of 1 s was applied. Treatment was considered complete when the entire nodule and its nearby 1 cm margin become hyperechoic on US. Pain relief after HIFU ablation was observed and the treated nodule received serial US examinations during follow-up. Results: All AWE was successfully ablated after one session of HIFU ablation, the ablation time lasted for 5-48 min (median 13 min), no major complications occurred. The cyclic pain disappeared in all patients during a mean follow-up of 18.7 months (range 3-31 months). The treated nodules gradually shank over time, 16 nodules became unnoticeable on US during follow-up. Conclusion: US-guided HIFU ablation appears to be safe and effective for the treatment of AWE.

    One of the main disadvantages of conventional ultrasound is its operator dependency, which might impede the reproducibility of the sonographic findings. A new approach with cine-loops and standardized scan protocols can overcome this drawback. To compare abdominal ultrasound findings of immediate bedside reading by performing radiologist with offline reading by a non-performing radiologist, using standardized cine-loop sequences. Over a 6-month period, three radiologists performed 140 dynamic ultrasound organ-based examinations in 43 consecutive outpatients. Examination protocols were standardized and included predefined probe position and sequences of short cine-loops of the liver, gallbladder, pancreas, kidneys, and urine bladder, covering the organs completely in two planes. After bedside examinations, the studies were reviewed and read out immediately by the performing radiologist. Image quality was registered from 1 (no diagnostic value) to 5 (excellent cine-loop quality). Offline reading was performed blinded by a radiologist who had not performed the examination. Bedside and offline reading were compared with each other and with consensus results. In 140 examinations, consensus reading revealed 21 cases with renal disorders, 17 cases with liver and bile pathology, and four cases with bladder pathology. Overall inter-observer agreement was 0.73 (95% CI 0.61-0.91), with lowest agreement for findings of the urine bladder (0.36) and highest agreement in liver examinations (0.90). Disagreements between the two readings were seen in nine kidneys, three bladder examinations, one pancreas and bile system examinations each, and in one liver, giving a total number of mismatches of 11%. Nearly all cases of mismatch were of minor clinical significance. The median image quality was 3 (range, 2-5) with most examinations deemed a quality of 3. Compared to consensus reading, overall accuracy was 96% for bedside reading and 94% for offline reading. Standardized cine

    Full Text Available Background: Blunt abdominal trauma is one of the causes of mortality in emergency department. Free fluid in the abdomen due to intra-abdominal blunt trauma can be determined by the surface probe of ultrasound. Since the importance of this free fluid in hemodynamic stable patients with blunt trauma is associated with the unknown outcome for surgeons, this study was performed to evaluate the role of ultrasound surface probe as a screening method in evaluating the patients with blunt abdominal trauma. Materials and Methods: A descriptive-analytical study was done on 45 patients with blunt abdominal trauma and hemodynamic stability. The patients were evaluated twice during the three-hours, including repeated ultrasound surface probe and clinical examinations. Computerized tomography was also performed. The patients were divided based on the amount of the free fluid in the abdomen during the evaluations into two groups: Fixed or increased, and decreased free fluid. The results of the different evaluated methods were compared using the sensitivity and specificity. Results: From 17 patients with CT abnormalities, free fluid increased in 14 patients (82.4%. Free fluid was decreased in three patients who were discharged well from the surgery service without any complication. Surface probe in prognosis detection had a sensitivity of 82.4% and specificity of 92.9%. The percentage of false positive and negative ultrasound compared with CT scan was 7.1% and 17.6%. Also, positive and negative predictive value of the ultrasound with surface probe was 87.5% and 89.7% respectively. Conclusion: The use of the ultrasound with surface probe in the diagnosis of free fluid in blunt abdominal trauma in hemodynamic stable patients can be considered as a useful screening method.

    Abdominal and obstetric applications of a dynamically focused phased array real time ultrasonic system are described. This work was performed utilising both the Thaumascan (two-dimensional, high resolution, actual time, ultrasound, multi-element array scanner) and the first commercial unit based on this system, the Grumman RT-400. Examples of normal and pathological anatomy are presented from over 300 examinations performed to date, including a series of 28 abdominal aortic aneurysms studied with the RT-400. Following electronic alterations in the Thaumascan with resultant improvement in the grey scale, prospective analyses in 86 obstetric and 23 abdominal examinations were undertaken. These studies indicate that fetal, intra-uterine, and abdominal structures can be rapidly and consistently imaged. The value of real time ultrasonic scanning in obstetric and abdominal examinations is illustrated. The principles of dynamically focused phased arrays are described, and the merits and limitations of these systems are discussed.

    2004-02-01

    Ultrasound imaging has been previously utilized in the measurement of muscle thickness and cross-sectional area in research studies, and advocated as a clinical biofeedback tool in the rehabilitation of transversus abdominis function following episodes of low back pain. This paper describes how the thickness of the abdominal muscles can be quantified with a new measurement technique using M-mode ultrasound. The technique uses a custom-made transducer holder that facilitates measurement of muscle thickness changes during functional activity. Limitations of the technique and potential future applications are discussed. The M-mode ultrasound technique may provide an effective method for the non-invasive measurement of abdominal muscle thickness during functional activities.

    This article theoretically studies the influence of inhomogeneous abdominal walls on focused therapeutic ultrasound based on the phase screen model. An inhomogeneous tissue is considered as a combination of a homogeneous medium and a phase aberration screen. Variations of acoustic parameters such as peak positive pressure, peak negative pressure, and acoustic intensity are discussed with respect to the phase screen statistics of human abdominal walls. Results indicate that the abdominal wall can result in energy loss of the sound in the focal plane. For a typical human abdominal wall with correlation length of 7.9 mm and variance of 0.36, the peak acoustic intensity radiated from a 1 MHz transmitter with a radius of 30 mm can be reduced by about 14% at the focal plane.

    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.

  3. Intra-abdominal adhesions in ultrasound. Part II: The morphology of changes

    Full Text Available Despite their frequent appearance, intra-abdominal adhesions are rarely the subject of clinical studies and academic discussions. For many years the operators have been trying to reduce such unfavourable consequences of interventions in the abdominal structures. The aim of this article is to present the possibilities of intra-abdominal adhesion diagnostics by means of ultrasound imaging based on authors’ own experience and information included in pertinent literature. The anatomy and examination technique of the abdominal wall were discussed in Part I of the article. In order to evaluate intraperitoneal adhesions, one should use a convex transducer with the frequency of 3.5–6 MHz. The article provides numerous examples of US images presenting intra-abdominal adhesions, particularly those which appeared after surgical procedures. The significance of determining their localisation and extensiveness prior to a planned surgical treatment is emphasized. Four types of morphological changes in the ultrasound caused by intra-abdominal adhesions are distinguished and described: visceroperitoneal adhesions, intraperitoneal adhesions, adhesive obstructions as well as adhesions between the liver and abdominal wall with a special form of such changes, i.e. hepatic pseudotumour. Its ultrasound features are as follows: 1. The lesion is localised below the scar in the abdominal wall after their incision. 2. The lesion is localised in the abdominal part of the liver segments III, IV and V. 3. With the US beam focus precisely set, the lack of fascia – peritoneum complex may be noticed. An uneven liver outline or its ventral displacement appears. 4. A hepatic adhesion-related pseudotumour usually has indistinct margins, especially the posterior one, and, gradually, from top to bottom, loses its hypoechogenic nature. 5. In a respiration test, this liver fragment does not present the sliding movement – a neoplastic tumour rarely shows such an effect

    To investigate the presence of widespread pressure pain sensitivity in cancer patients following partial colorectal resection in the abdominal and lower back area and to describe the presence of abnormalities in abdominal and lower back muscle morphology. Twenty colon cancer survivors (eight females, mean age 56.60 ± 7.76 years) and 20 matched healthy controls (10 females, mean age 54.22 ± 8.12 years) participated. Abdominal and lower back pain was assessed after undergoing surgery using a Visual Analogue Scale (VAS) and Brief Pain Inventory (BPI). Pressure pain thresholds (PPTs) were bilaterally assessed over the supraumbilical, infraumbilical, and lower back areas and the second metacarpal. Ultrasound imaging was used to measure the depth of the abdominal muscles, the width of the midline abdominal fascia and the width of the lumbar multifidus. Ten months after finishing oncological treatments, patients who underwent partial colorectal resection reported significantly higher pain levels in the low-back area (P = 0.003) but not in the abdominal area (P = 0.426) compared with the matched controls. After surgery, the colon patients reported significantly higher BPI-intensity (P ultrasound imaging of the depth of the internal oblique muscle (F = 4.887, P = 0.035) but not in the other ultrasound imaging measurements. Ten months after oncology treatment, colon cancer survivors show widespread pressure pain muscle hyperalgesia and reduced depths of dominant-side internal oblique muscles compared with matched controls.

    Purpose: This study was performed to evaluate the accuracy of upper abdominal ultrasound (US) scanning performed by sonographers in a district general hospital, to identify potential areas of weakness and to make recommendations to improve the service. Materials and methods: Upper abdominal US examinations performed and reported by sonographers over a 4-week period were retrospectively reviewed. The accuracy of the imaging findings and reports were assessed against other imaging, surgical, histological or laboratory findings and against clinical outcome. Results: A heterogenous group of 104 patients were included in the study, 62 of whom had an US abnormality. Errors of scanning or interpretation were identified in 10 patients (9.6%) of whom five (4.8%) were felt to be potentially significant. Conclusions: The sonographers' accuracy in reporting upper abdominal US scans was 90%. However, on the basis of this study we have implemented specific recommendations to improve the quality of the service

    Head-to-head comparison of ultrasound and CT accuracy in common diagnoses causing acute abdominal pain. Consecutive patients with abdominal pain for >2 h and <5 days referred for imaging underwent both US and CT by different radiologists/radiological residents. An expert panel assigned a final diagnosis. Ultrasound and CT sensitivity and predictive values were calculated for frequent final diagnoses. Effect of patient characteristics and observer experience on ultrasound sensitivity was studied. Frequent final diagnoses in the 1,021 patients (mean age 47; 55% female) were appendicitis (284; 28%), diverticulitis (118; 12%) and cholecystitis (52; 5%). The sensitivity of CT in detecting appendicitis and diverticulitis was significantly higher than that of ultrasound: 94% versus 76% (p < 0.01) and 81% versus 61% (p = 0.048), respectively. For cholecystitis, the sensitivity of both was 73% (p = 1.00). Positive predictive values did not differ significantly between ultrasound and CT for these conditions. Ultrasound sensitivity in detecting appendicitis and diverticulitis was not significantly negatively affected by patient characteristics or reader experience. CT misses fewer cases than ultrasound, but both ultrasound and CT can reliably detect common diagnoses causing acute abdominal pain. Ultrasound sensitivity was largely not influenced by patient characteristics and reader experience. (orig.)

    The purpose of this study is to evaluate transfer learning with deep convolutional neural networks for the classification of abdominal ultrasound images. Grayscale images from 185 consecutive clinical abdominal ultrasound studies were categorized into 11 categories based on the text annotation specified by the technologist for the image. Cropped images were rescaled to 256 × 256 resolution and randomized, with 4094 images from 136 studies constituting the training set, and 1423 images from 49 studies constituting the test set. The fully connected layers of two convolutional neural networks based on CaffeNet and VGGNet, previously trained on the 2012 Large Scale Visual Recognition Challenge data set, were retrained on the training set. Weights in the convolutional layers of each network were frozen to serve as fixed feature extractors. Accuracy on the test set was evaluated for each network. A radiologist experienced in abdominal ultrasound also independently classified the images in the test set into the same 11 categories. The CaffeNet network classified 77.3% of the test set images accurately (1100/1423 images), with a top-2 accuracy of 90.4% (1287/1423 images). The larger VGGNet network classified 77.9% of the test set accurately (1109/1423 images), with a top-2 accuracy of VGGNet was 89.7% (1276/1423 images). The radiologist classified 71.7% of the test set images correctly (1020/1423 images). The differences in classification accuracies between both neural networks and the radiologist were statistically significant (p ultrasound images.

    The aim of this preliminary study was to determine the differences in abdominal musculature thickness, within 1 month of delivery, in women who experienced back pain during pregnancy compared with those who did not. B-mode ultrasound imaging was used to measure abdominal muscle thickness on 76 postpartum participants who participated in a larger study; 47 women experienced back pain during pregnancy, and 29 did not. Participant data were stratified by group, and primary comparisons were based on these grouping across the abdominal muscles, including rectus abdominis (upper and lower fibers), external oblique, internal oblique, and transversus abdominis. Means and standard deviations were also used to set parameters for future studies. In the present study, there was no difference in any abdominal muscle thickness between groups. Women with low back pain were significantly shorter (165.19 ± 6.64 cm) than women who did not have from back pain during pregnancy (169.38 ± 7.58 cm). All other demographics, such as age, weight, and date tested postpartum, were not significantly different between groups. The results of this study showed no variation in abdominal muscle thickness in women who had back pain during pregnancy and those who did not. Copyright © 2017. Published by Elsevier Inc.

    Rehabilitative ultrasound imaging (RUSI) measures of abdominal wall muscles are used to indirectly measure muscle activity. These measures are used to identify suitable patients and to monitor progress of motor control exercise treatment of people with low back pain. The purpose of this study was to systematically review reproducibility studies of RUSI for measuring thickness of abdominal wall muscles. Eligible studies were identified via searches of MEDLINE, EMBASE, and CINAHL. The authors also searched personal files and tracked references of the retrieved studies via the Web of Science Index. Studies involving any type of reliability and or agreement of any type of ultrasound measurements (B or M mode) for any of the abdominal wall muscles were selected. Two independent reviewers extracted data and assessed methodological quality. Due to heterogeneity of the studies' designs, pooling the data for a meta-analysis was not possible. Twenty-one studies were included, and these studies were typically of low quality and studied subjects who were healthy rather than people seeking care for low back pain. The studies reported good to excellent reliability for single measures of thickness and poor to good reliability for measures of thickness change (reflecting the muscle activity). Interestingly, no studies checked reliability of measures of the difference in thickness changes over time (representing improvement or deterioration in muscle activity). The current evidence of the reproducibility of RUSI for measuring abdominal muscle activity is based mainly on studies with suboptimal designs and the study of people who were healthy. The critical question of whether RUSI provides reliable measures of improvement in abdominal muscle activity remains to be evaluated.

    To evaluate the usefulness of abdominal sonography in the fasting state with no hypotonic agents in the detection and exclusion of gastric lesions. One-hundred patients with normal upper gastrointestinal endoscopy, 94 patients with a major gastric abnormality (including 59 intraluminal tumors, three submucosal masses, 29 ulcers, two polyps and one hypertrophied gastric mucosa) and 75 patients with minor gastric abnormalities (mainly gastritis) were enrolled into the study. Of the 100 normal patients, ultrasound showed four false positive results with 96% specificity of the examination. Within the major gastric lesion group, ultrasound was true positive in 55 of 59 tumors, 15 of 29 ulcers, three of three submucosal masses and the case of giant gastric mucosa. It was negative in the detection of gastric polyps. It could detect only 8% of minor gastric abnormalities. Abdominal sonography in the fasting state, if carefully performed, is sufficiently accurate in detection and exclusion of major gastric lesions. Therefore, although it cannot replace endoscopic and barium studies of the stomach, careful evaluation of the stomach is recommended in every sonographic evaluation of the abdominal cavity

    Objective: To compare sonographer findings with radiologists' reports regarding the level of agreement, ability to answer the clinical question, and the use of hedging (descriptive words that do not commit to a definitive diagnosis) in abdominal ultrasound cases referred by the Emergency department. Other criteria compared included caveats of image quality and requests for further investigations. Methods: Abdominal ultrasound examinations referred by the Emergency department at a large regional tertiary hospital were retrospectively reviewed and sonographer findings compared with radiologists' reports. A consultant Intensivist scored all examinations into one of four categories according to the level of diagnostic agreement between the sonographer and associated radiologists. The same rater also identified where hedging terminology was used, whether the clinical question posed was answered and when further requests for investigations (including imaging) were made. The proportion of scores between sonographers and radiologists for each outcome variable were analysed using Fisher Exact tests. Results: Eighty-six cases were identified for this study. Of those, 73 (84.9%) were in complete agreement. In 12 cases (14.0%) a minor discrepancy was reported and only one case (1.1%) was scored as moderately discrepant between sonographers findings and radiologists' reports. There were no significant differences in the use of hedging, ability to answer the clinical question, requests for further investigations or interpretation of image quality. Conclusion: Sonographer findings for cases of abdominal ultrasound referred by the Emergency department have a high level of agreement with radiologists' reports and could form the basis for acute patient care when radiologists' reports are unavailable

    The study was designed to evaluate the intra-examiner reliability of ultrasound (US) thickness measurement of abdominal muscles activity when supine lying and during two isometric endurance tests in subjects with and without Low back pain (LBP). A total of 19 women (9 with LBP, 10 without LBP) participated in the study. Within-day reliability of the US thickness measurements at supine lying and the two isometric endurance tests were assessed in all subjects. The intra-class correlation coefficient (ICC) was used to assess the relative reliability of thickness measurement. The standard error of measurement (SEM), minimal detectable change (MDC) and the coefficient of variation (CV) were used to evaluate the absolute reliability. Results indicated high ICC scores (0.73-0.99) and also small SEM and MDC scores for within-day reliability assessment. The Bland-Altman plots of agreement in US measurement of the abdominal muscles during the two isometric endurance tests demonstrated that 95% of the observations fall between the limits of agreement for test and retest measurements. Together the results indicate high intra-tester reliability for the US measurement of the thickness of abdominal muscles in all the positions tested. According to the study's findings, US imaging can be used as a reliable method for assessment of abdominal muscles activity in supine lying and the two isometric endurance tests employed, in participants with and without LBP.

    2014-06-01

    For ultrasound reports to meet criteria for coding as abdomen complete (USABC), 8 elements are required: liver, bile ducts, gallbladder, spleen, kidneys, pancreas, inferior vena cava (IVC), and aorta. Failure to document all 8 results in coding as ultrasound abdomen limited. The purposes of our study were to identify deficiencies in documentation, implement a performance improvement intervention to address deficiencies, and evaluate the intervention. In the first phase, 50 consecutive USABC reports performed as part of routine medical care were retrospectively analyzed for the presence or absence of the 8 elements required for USABC coding. Subsequently, education regarding current procedural terminology coding in abdominal ultrasound and standardized macros was provided to radiologists. In the second, postintervention phase, an additional 50 consecutive USABC reports were analyzed for the presence or absence of the 8 elements. In the first phase, none (0%) of 50 reports met criteria for USABC. The most commonly omitted elements were IVC (present in 2% of reports) and aorta (present in 6%). After intervention, there was an increase to 37 reports (74%) meeting criteria for USABC. The most commonly omitted elements were IVC (present in 76%) and aorta (present in 86%). Lack of 100% compliance was secondary to failure to update a macro and inaccurately scheduled studies (focused right lower quadrant/appendicitis study scheduled as USABC). We improved USABC documentation from 0% to 74%. Our compliance rate after intervention was similar to the 75.1% of previously published larger studies. Our study illustrates the efficacy of simple performance improvement interventions to improve abdominal ultrasound documentation.

    Full Text Available Aim. To investigate the value of contrast-enhanced ultrasound (CEUS guided biopsy of undetermined abdominal lesions in multidisciplinary treatment (MDT decision-making approach. Methods. Between Jan 2012 and Dec 2015, 60 consecutive patients (male, 37; female, 23; mean age, 51.3 years ± 14.6 who presented with undetermined abdominal lesions were included. CEUS and core needle percutaneous biopsy was performed under real-time CEUS guidance in all lesions. Data were recorded and compared with conventional ultrasound (US guidance group (n=75. All CEUS findings and clinical data were evaluated in MDT. Results. CEUS enabled the delimitation of more (88.3% versus 41.3% and larger (14.1 ± 10.7 mm versus 32.3 ± 18.5 mm nonenhanced necrotic areas. More inner (20.0% versus 6.7% and surrounding (18.3% versus 2.7% major vessels were visualized and avoided during biopsies. CEUS-guided biopsy increased the diagnostic accuracy from 93.3% to 98.3%, with correct diagnosis in 57 of 60 lesions (95.0%. The therapeutic plan was influenced by CEUS guided biopsies findings in the majority of patients (98.3%. Conclusion. The combination of CEUS guided biopsy and MDT decision-making approach is useful in the diagnostic work-up and therapeutic management.

    Full Text Available We determined the feasibility of abdominal aortic aneurysm (AAA screening program led by family physicians in public primary healthcare setting using hand-held ultrasound device. The potential study population was 11,214 men aged ≥ 60 years attended by three urban, public primary healthcare centers. Participants were recruited by randomly-selected telephone calls. Ultrasound examinations were performed by four trained family physicians with a hand-held ultrasound device (Vscan®. AAA observed were verified by confirmatory imaging using standard ultrasound or computed tomography. Cardiovascular risk factors were determined. The prevalence of AAA was computed as the sum of previously-known aneurysms, aneurysms detected by the screening program and model-based estimated undiagnosed aneurysms. We screened 1,010 men, with mean age of 71.3 (SD 6.9 years; 995 (98.5% men had normal aortas and 15 (1.5% had AAA on Vscan®. Eleven out of 14 AAA-cases (78.6% had AAA on confirmatory imaging (one patient died. The total prevalence of AAA was 2.49% (95%CI 2.20 to 2.78. The median aortic diameter at diagnosis was 3.5 cm in screened patients and 4.7 cm (p<0.001 in patients in whom AAA was diagnosed incidentally. Multivariate logistic regression analysis identified coronary heart disease (OR = 4.6, 95%CI 1.3 to 15.9 as the independent factor with the highest odds ratio. A screening program led by trained family physicians using hand-held ultrasound was a feasible, safe and reliable tool for the early detection of AAA.

    To investigate the usefulness of magnetic resonance imaging (MRI) in the evaluation of pregnant women with acute abdominal and pelvic pain after sonographically (US) indeterminate findings. Forty pregnant patients with acute abdominal and/or pelvic pain, in whom ultrasound was indeterminate, were included in this study. Multiplanar MR images of the abdomen and pelvis were obtained and independently reviewed by two radiologists with discrepancies were resolved by consensus. Correlation of prospective clinical MR interpretations with surgical and obstetric records and clinical follow-up showed correct identification of disease entities in all 40/40 patients. The following disease processes were correctly identified using MRI in 21/40 patients: appendicitis (n = 5), ileal volvulus (n = 1), common bile duct lithiasis (n = 2), pubic chondrosarcoma (n = 1), uterine dehiscence (n = 1), placental hematoma (n = 3), iliac venous thrombosis (n = 2), ulcerative colitis (n = 1), acute pancreatitis (n = 1), hydronephrosis (n = 1), ovarian dermoid (n = 1), and ovarian torsion (n = 2). 19 of the 40 patients had normal findings on MR examinations and unremarkable follow-up. Interobserver agreement for lesion detection was excellent (0.95 k). Magnetic resonance imaging (MRI) is an accurate investigation in detecting the cause of acute abdominal and pelvic pain during pregnancy and should be considered after US indeterminate findings.

    To evaluate the association between visceral fat and cardiovascular risk factors and to compare the ultrasonographic measurements of abdominal visceral fat with abdominal circumference (AC). This observational cross-sectional study categorized pubertal and postpubertal adolescents into a control group (n = 49) and an obese group (n = 46). Weight, height, AC, blood pressure, biochemical tests (lipid profile, triacylglycerols, fasting glucose for insulinemia, and serum uric acid), and ultrasound to measure visceral fat were assessed. We found significant differences in the vascular risk variables between the groups, except for total cholesterol and fasting blood glucose level. We also observed that 31 subjects in the control group presented abnormalities in cardiovascular risk factors. The correlations between abdominal visceral fat (measured by ultrasound or the AC) and cardiovascular risk factors were significant. In the entire sample, AC presented better sensitivity and specificity than the ultrasound-measured abdominal visceral fat for identifying the presence of a cluster of at least three cardiovascular risk factors (areas under the receiver operating characteristics curve 0.87 and 0.73, respectively). Ultrasonographic measurements of visceral fat were correlated with cardiovascular risk factors, but this association was also demonstrable with AC measurements. Our results suggest that the measurement of visceral fat by ultrasound is unnecessary for the diagnosis of cardiovascular risk in well-nourished or obese adolescents. Copyright © 2013 Elsevier Inc.

    Full Text Available The aim of the present study was the ultrasound characterization of the abdominal and pelvic regions of five maned wolves kept in captivity at the Triage Center of Wild Animals of the Federal University of Viçosa (Centro de Triagem de Animais Silvestres, Universidade Federal de Viçosa. This characterization included descriptions of ultrasonographic aspects and measurements of various structures using B-mode ultrasound. Biometric data were collected to assess the existence of significant linear correlations between these measurements and the measurements obtained by ultrasound. Additionally, hematological and serum biochemistry evaluations of the animals were performed. The ultrasound findings were similar to those available in the literature on domestic dogs, which were used for comparison as a result of the lack of published data regarding maned wolves. The latter species showed characteristics closely resembling those of the former, differing in the spleen and left renal cortex echogenicities, in the appearance of the prostatic and testicular regions and in the hepatic portal vein morphology. In the current study, the biometric values were similar to those previously published; however, no data regarding thoracic perimeter, modified crown-rump length or thoracic depth were found in the literature for this Canidae species. Statistical analysis showed the existence of a strong negative correlation between the modified crown-rump length and left renal length, between the modified crown-rump length and the right renal volume, between the thoracic perimeter and the height at the cranial pole of the left adrenal gland and between the thoracic perimeter and the height at the caudal pole of the left adrenal gland.

    Due to the characteristic artifacts of ultrasound images, e.g., speckle noise, shadows and intensity inhomogeneity, traditional intensity-based methods usually have limited success on the segmentation of fetal abdominal contour. This paper presents a novel approach to detect and measure the abdominal contour from fetal ultrasound images in two steps. First, a local phase-based measure called multiscale feature asymmetry (MSFA) is de ned from the monogenic signal to detect the boundaries of fetal abdomen. The MSFA measure is intensity invariant and provides an absolute measurement for the signi cance of features in the image. Second, in order to detect the ellipse that ts to the abdominal contour, the iterative randomized Hough transform is employed to exclude the interferences of the inner boundaries, after which the detected ellipse gradually converges to the outer boundaries of the abdomen. Experimental results in clinical ultrasound images demonstrate the high agreement between our approach and manual approach on the measurement of abdominal circumference (mean sign difference is 0.42% and correlation coef cient is 0.9973), which indicates that the proposed approach can be used as a reliable and accurate tool for obstetrical care and diagnosis.

    Synergistic co-activation of the abdominal and pelvic floor muscles (PFM) has been shown in literature. Some studies have assessed the reliability of ultrasound measures of the abdominal muscles. The aim of this study was to determine the reliability of ultrasound measurements of transverses abdominis (TrA) and obliquus internus (OI) muscles during different conditions (PFM contraction, abdominal hollowing manoeuvre (AHM) with and without PFM contraction) in participants with and without chronic low back pain (LBP). 21 participants (9 with LBP, 12 healthy) participated in the study. The reliability of thickness measurements at rest and during each condition and thickness changes and percentage of this changes at different conditions were assessed. The results showed high reliability of the thickness measurement at rest and during each condition of TrA and OI muscles, moderate to substantial reliability for the thickness change and percentage of thickness change of TrA, and fair to moderate reliability of the thickness change and percentage of thickness change of OI in both groups. Ultrasound imaging can be used as a reliable method for assessment of abdominal muscle activity with and without PFM contraction.

    Full Text Available Introduction: A bdominal muscles are key to both posture andgait in both children with typical development (TD and with disabilities.Ultrasound (US imaging is a potential non-invasive method for investigatingactivity in these muscles. This study therefore aimed to determine the inter-tester and intra-tester reliability of B-mode US for investigating transverseabdominus (TrA , rectus abdominus (RA and external- (EO and internaloblique (IO muscle activity in children with TD. Design: A  prospective cor-relational descriptive study.  Participants:  Eighty six, 6-13year old children from one private and one public mainstream school. Outcome measures: Two sets of B-mode US images where captured per subject during rest and during head-up, resisted head-up and resisted sling activities. Intra-class Correlation Coefficients (ICC and standard error of measurement (SEM were used to analyse the data. Results: Good correlation was found for both test - retest condi-tions for all four muscles tested during rest: 0.91(TrA ; 0.90(IO; 0.91(EO; 0.94(RA for intra-tester reliability and0.74(TrA ; 0.88(IO; 0.74(EO; 0.83(RA for inter-tester reliability. Repeatability of thickness measures during activity however showed variation in recruitment patterns. A  significant correlation was found between age and BMI andresting abdominal muscle thickness (p<0.001. Conclusion: The study supports the reliability of US measurement of resting abdominal muscles and of the RA  under active conditions in children aged six to 13. However the stability o measurement of the other muscles under active conditions still needs to be established.

    Randomized controlled trial among patients with low back pain (LBP). (1) Determine the reliability of real-time ultrasound imaging for assessing activation of the lateral abdominal muscles; (2) characterize the extent to which the abdominal drawing-in maneuver (ADIM) results in preferential activation of the transverse abdominis (TrA); and (3) determine if ultrasound biofeedback improves short-term performance of the ADIM in patients with LBP. Ultrasound imaging is reportedly useful for measuring and training patients to preferentially activate the TrA muscle. However, research to support these claims is limited. Thirty patients with LBP referred for lumbar stabilization training were randomized to receive either traditional training (n = 15) or traditional training with biofeedback (n = 15). Ultrasound imaging was used to measure changes in thickness of the lateral abdominal muscles. Differences in preferential changes in muscle thickness of the TrA between groups and across time were assessed using analysis of variance. Intrarater reliability measuring lateral abdominal muscle thickness exceeded 0.93. On average, patients in both groups demonstrated a 2-fold increase in the thickness of the TrA during the ADIM. Performance of the ADIM did not differ between the groups. These data provide construct validity for the notion that the ADIM results in preferential activation of the TrA in patients with LBP. Although, the addition of biofeedback did not enhance the ability to perform the ADIM at a short-term follow-up, our data suggest a possible ceiling effect or an insufficient training stimulus. Further research is necessary to determine if there is a subgroup of patients with LBP who may benefit from biofeedback.

    Constipation has been shown to have a significant impact on lower urinary tract symptoms (LUTS) in children, and treatment of constipation in children with bowel bladder dysfunction (BBD) has been shown to improve or completely resolve LUTS in many cases. Recent studies utilizing trans-abdominal ultrasound (US) to assess stool burden have correlated diagnosis of constipation with US appearance of rectal stool. An US scoring tool was published in 2008 to assess stool burden, showing linear correlation with constipation severity by symptom questionnaire in an outpatient pediatric constipation clinic population. We hypothesized that this US scoring tool would correlate with constipation symptoms in our outpatient pediatric urology population. In 2010, our pediatric urology outpatient clinic began administering a previously published validated BBD questionnaire to new toilet-trained patients, containing three questions addressing bowel function. Patients in our clinic undergoing trans-abdominal US of the bladder also have assessment of their stool burden by the previously published US scoring tool. We retrospectively reviewed patient charts beginning in June 2013 who had undergone trans-abdominal US of the bladder, gathering data on the first 100 patients with a complete BBD questionnaire and a completed stool burden US scoring tool. Chart review of 272 consecutive patients was required to enroll 100 patients with a completed US scoring of stool burden and a completed BBD questionnaire. Of these 272 patients, 225 (82%) had a complete scoring of stool burden during their US examination. BBD questionnaires were complete in 107 of 272 patients (39%). Median patient age was 8.2 years, with 69% of patients being female. The most common diagnosis was incontinence or bladder dysfunction (41%). Only one patient (1%) had constipation as the primary diagnosis for their visit. Linear regression analysis showed no correlation of US score to patient reported frequency of bowel

  10. Echinococcus multilocularis Detection in Live Eurasian Beavers (Castor fiber Using a Combination of Laparoscopy and Abdominal Ultrasound under Field Conditions.

    Full Text Available Echinococcus multilocularis is an important pathogenic zoonotic parasite of health concern, though absent in the United Kingdom. Eurasian beavers (Castor fiber may act as a rare intermediate host, and so unscreened wild caught individuals may pose a potential risk of introducing this parasite to disease-free countries through translocation programs. There is currently no single definitive ante-mortem diagnostic test in intermediate hosts. An effective non-lethal diagnostic, feasible under field condition would be helpful to minimise parasite establishment risk, where indiscriminate culling is to be avoided. This study screened live beavers (captive, n = 18 or wild-trapped in Scotland, n = 12 and beaver cadavers (wild Scotland, n = 4 or Bavaria, n = 11, for the presence of E. multilocularis. Ultrasonography in combination with minimally invasive surgical examination of the abdomen by laparoscopy was viable under field conditions for real-time evaluation in beavers. Laparoscopy alone does not allow the operator to visualize the parenchyma of organs such as the liver, or inside the lumen of the gastrointestinal tract, hence the advantage of its combination with abdominal ultrasonography. All live beavers and Scottish cadavers were largely unremarkable in their haematology and serum biochemistry with no values suspicious for liver pathology or potentially indicative of E. multilocularis infection. This correlated well with ultrasound, laparoscopy, and immunoblotting, which were unremarkable in these individuals. Two wild Bavarian individuals were suspected E. multilocularis positive at post-mortem, through the presence of hepatic cysts. Sensitivity and specificity of a combination of laparoscopy and abdominal ultrasonography in the detection of parasitic liver cyst lesions was 100% in the subset of cadavers (95%Confidence Intervals 34.24-100%, and 86.7-100% respectively. For abdominal ultrasonography alone sensitivity was only 50% (95%CI 9

    Rupture risk in abdominal aortic aneurysms (AAAs) is assessed using AAA diameter; yet 10% of ruptures occur in a small aneurysm. This underlines the inadequacy of diameter as a standalone parameter. In this prospective follow-up study, ultrasound determined aneurysm diameter was compared with aneurysm volume determined by three dimensional ultrasound (3D-US) in a group of 179 AAAs. This was a prospective cohort study with repeated diameter and volume measurements by 3D-US. In total, 179 patients with small infrarenal AAAs (diameter 30-55 mm) were enrolled consecutively. At enrolment and at 12 month follow-up, maximum diameter, using dual plane technique, and three dimensional volume were measured. Based on a previous accuracy study, significant change in diameter and volume were defined as an increase exceeding the known range of variability (ROV) of each US technique; ±3.7 mm and ±8.8 mL, respectively. Post-hoc Kaplan-Meier analysis was performed to estimate time to conversion to treatment after the conclusion of the follow-up period between two groups. In total, 125 patients (70%) had an unchanged diameter during follow-up. In this group, 50 patients (40%) had an increasing aortic volume. Forty-five (83%) of the 54 patients with an increasing aortic diameter showed a corresponding volume increase. During a median follow-up of 367 days (364-380 days), a mean increase in diameter of 2.7 mm (±2.6 mm) and a mean increase in volume of 11.6 mL (±9.9 mL) were recorded. In post-hoc analysis, it was found that more AAAs with a stable diameter and a growing volume than AAAs with a stable diameter and volume were undergoing aortic repair during follow-up, based on the maximum diameter. In this cohort of small AAAs, 40% of patients with a stable diameter had an increasing volume at 12 month follow-up. From this perspective, 3D-US could have a future supplemental role in AAA surveillance programmes. Copyright © 2017 European Society for Vascular Surgery. Published

    Observational study. Are there deviations in the thickness of abdominal muscles at rest in individuals with adolescent idiopathic scoliosis (AIS)? Are there deviations in abdominal muscular activity in people with AIS during the active straight leg raise (ASLR) test? Ultrasound imaging can be used to assess the lateral abdominal muscle. Some authors suggest that scoliosis develops through a weakness or improper functioning of the abdominal muscles that cannot provide adequate support to the spinal segments. However, the literature lacks studies on the functioning of the abdominal muscles in individuals with spinal deviations. This study focuses on the evaluation of the thickness of the external oblique (EO), internal oblique (IO), and transversus abdominalis (TrA) muscles of individuals with AIS. Seventy-one healthy adolescents and 71 patients with AIS, all aged 10-16 years, were studied. The thickness of the muscles at rest was measured at the end of normal exhalation in millimeters. Muscular activity during the ASLR test was measured in the final position, and the standards were normalized with the thickness produced at rest. Muscular activity during the ASLR test was represented as a percentage change in the muscle thickness. The AIS group demonstrated a smaller resting thickness of all tested muscles of both sides (Pmuscles on the right side of the body showed higher activity in the AIS group during the ASLR test (Pactivity of the EO, IO, and TrA muscles on the right side.

    Objective: To compare duplex ultrasound and computed tomography (CT) angiography in terms of their performance in detecting endoleaks, as well as in determining the diameter of the aneurysm sac, in the postoperative follow-up of endovascular abdominal aortic aneurysm repair. Materials and Methods: This was a prospective study involving 30 patients who had undergone endovascular repair of infrarenal aortoiliac aneurysms. Duplex ultrasound and CT angiography were performed simultaneously by independent radiologists. Measurements of the aneurysm sac diameter were assessed, and the presence or absence of endoleaks was determined. Results: The average diameter of the aneurysm sac, as determined by duplex ultrasound and CT angiography was 6.09 ± 1.95 and 6.27 ± 2.16 cm, respectively. Pearson's correlation coefficient showing a statistically significant correlation (R = 0.88; p < 0.01). Comparing the duplex ultrasound and CT angiography results regarding the detection of endoleaks, we found that the former had a negative predictive value of 92.59% and a specificity of 96.15%. Conclusion: Our results show that there is little variation between the two methods evaluated, and that the choice between the two would have no significant effect on clinical management. Duplex ultrasound could replace CT angiography in the postoperative follow-up of endovascular aneurysm repair of the infrarenal aorta, because it is a low-cost procedure without the potential clinical complications related to the use of iodinated contrast and exposure to radiation.

    Ultrasound and electromyographic (EMG) measures of trunk muscle activity were compared between low back pain (LBP) and control subjects in a cross-sectional study. To compare the recruitment of the abdominal muscles (measured as a change in thickness with ultrasound imaging) between people with and without low back pain and to compare these measurements with EMG recordings made with intramuscular electrodes. Although ultrasonography has been advocated as a noninvasive measure of abdominal muscle activity, it is not known whether it can provide a valid measure of changes in motor control of the abdominal muscles in LBP. Ten subjects with recurrent LBP and 10 matched controls were tested during isometric low load tasks with their limbs suspended. Changes in thickness from resting baseline values were obtained for transversus abdominis (TrA), obliquus internus (OI), and obliquus externus (OE) using ultrasonography. Fine wire EMG was measured concurrently. Study participants with LBP had a significantly smaller increase in TrA thickness with isometric leg tasks compared with controls. No difference was found between groups for OI or OE. Similar results were found for EMG. People with LBP had less TrA EMG activity with leg tasks, and there was no difference between groups for EMG activity for OI or OE. This study reinforces evidence for changes in automatic control of TrA in people with LBP. Furthermore, the data establish a new test of recruitment of the abdominal muscles in people with LBP. This test presents a feasible noninvasive test of automatic recruitment of the abdominal muscles.

    Full Text Available Abstract Background- Neonatal abdominal ultrasound is usually performed in Nigeria to investigate neonatal symptoms rather than as a follow up to evaluate fetal abnormalities which were detected on prenatal ultrasound. The role of routine obstetric ultrasonography in the monitoring of pregnancy and identification of fetal malformations has partly contributed to lowering of fetal mortality rates. In Nigeria which has a high maternal and fetal mortality rate, many pregnant women do not have ante-natal care and not infrequently, women also deliver their babies at home and only bring the newborns to the clinics for immunization. Even when performed, most routine obstetric scans are not targeted towards the detection of fetal abnormalities. The aim of the present study is to evaluate the benefit of routinely performing abdominal scans on newborns with a view to detecting possible abnormalities which may have been missed ante-natally. Methods- This was a longitudinal study of 202 consecutive, apparently normal newborns. Routine clinical examination and abdominal ultrasound scans were performed on the babies by their mother's bedside, before discharge. Neonates with abnormal initial scans had follow-up scans. Results- There were 108 males and 94 females. There were 12 (5.9% abnormal scans seen in five male and seven female neonates. Eleven of the twelve abnormalities were in the kidneys, six on the left and five on the right. Three of the four major renal anomalies- absent kidney, ectopic/pelvic kidney and two cases of severe hydronephrosis were however on the left side. There was one suprarenal abnormality on the right suspected to be a possible infected adrenal haemorrage. Nine of the abnormal cases reported for follow- up and of these, two cases had persistent severe abnormalities. Conclusions- This study demonstrated a 5.9% incidence of genito urinary anomalies on routine neonatal abdominal ultrasound in this small population. Routine obstetric USS

    Trauma is a major cause of morbidity and mortality in an age group including from teenagers to young adults, in a male dominant proportion, resulting in great economic and social impact. Within the complex of trauma, blunt abdominal trauma (BAT) is frequent event and presents difficulty in the evaluation and management since the clinical examination shows low sensitivity and specificity. The detection of hemo peritoneum is one of the methods of evaluation of possible indirect intra-abdominal injuries, initially using direct diagnostic abdominal paracentesis and posteriorly the diagnostic peritoneal lavage, that despite the effectiveness, have drawbacks such as invasiveness and the inability of hemo peritoneum quantification and the lesion staging, resulting in non-therapeutic laparotomies. Imaging methods provide useful information in the investigation of abdominal injuries, such as conventional and contrast radiology, ultrasound (US) and computed tomography (CT), which is the best effective method, but has its own drawbacks, such as cost, accessibility, use of ionizing radiation and contrast media and the displacement of the patient to the machine. US presents itself as an alternative in the initial evaluation of these patients as noninvasive method, with lack of harmfulness, low cost, fast answer and portability. Nevertheless, this method also has its limitations, as in cases of abdominal injuries without free fluid. This study was conducted in order to establish the performance of the US in this setting, allowing to rationalise the use of CT. For this purpose we studied 163 patients treated in the ER of HC/FMUSP, with the completion of consecutive US and CT. The population fits the usual profile of trauma victims, with 83% male, 56% in the age group between 20 and 39 years and in 73% of cases victims of traffic accidents. They were brought to the service in an average time of 51 minutes, mainly stable and with satisfactory level of consciousness. US took on

    Ultrasound-guided percutaneous core needle biopsy (USPCB) is used extensively in daily clinical practice for the pathologic confirmation of both focal and diffuse diseases of the abdominal viscera. As a guidance tool, US has a number of clear advantages over computerized tomography or magnetic resonance imaging: fewer false-negative biopsies, lack of ionizing radiation, portability, relatively short procedure time, real-time intra-procedural visualization of the biopsy needle, ability to guide the procedure in almost any anatomic plane, and relatively lower cost. Notably, USPCB is widely used to retrieve tissue specimens in cases of hepatic lesions. However, general radiologists, particularly beginners, find USPCB difficult to perform in abdominal organs other than the liver; indeed, a full understanding of the entire USPCB process and specific considerations for specific abdominal organs is necessary to safely obtain adequate specimens. In this review, we discuss some points and techniques that need to be borne in mind to increase the chances of successful USPCB. We believe that the tips and considerations presented in this review will help radiologists perform USPCB to successfully retrieve target tissue from different organs with minimal complications.

    We aimed to evaluate the effect of bupivacaine and dexmedetomidine added to bupivacaine used in tranversus abdominis plane (TAP) block on postoperative pain and patient satisfaction in patients undergoing lower abdominal surgery. Patients submitted to lower abdominal surgery were enrolled in the study. After anesthesia induction, ultrasound guided TAP block was performed. TAP block was obtained with 21mL 0.9% saline in Group C (n=31), 20mL 0.5% bupivacaine+1mL saline in Group B (n=31), and 20mL 0.5% bupivacaine+1mL dexmedetomidine (100μg) in Group BD (n=31). Visual analog scale scores were lower in Group BD compared to Group C, at all time points (p0.05). The addition of dexmedetomidine to bupivacaine on TAP block decreased postoperative pain scores and morphine consumption; it also increased patient satisfaction in patients undergoing lower abdominal surgery. Dexmedetomidine did not have any effect on nausea and vomiting score and antiemetic requirement. Copyright © 2017 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

    Full Text Available Sarcopenia has never been diagnosed based on site-specific muscle loss, and little is known about the relationship between site-specific muscle loss and metabolic syndrome (MetS risk factors. To this end, this cross-sectional study aimed to investigate the relationship between site-specific muscle size and MetS risk factors. Subjects were 38 obese men and women aged 40-82 years. Total body fat and lean body mass were assessed by whole-body dual-energy X-ray absorptiometry (DXA scan. Muscle thickness (MTH was measured using B-mode ultrasound scanning in six body regions. Subjects were classified into general obesity (GO and sarcopenic obesity (SO groups using the threshold values of one standard deviation below the sex-specific means of either MTH or skeletal muscle index (SMI measured by DXA. MetS risk score was acquired by standardizing and summing the following continuously distributed variables: visceral fat area, mean blood pressure, HbA1c, and serum triglyceride / high density lipoprotein cholesterol, to obtain the Z-score. Multiple regression analysis revealed that the MetS risk score was independently associated with abdominal MTH in all subjects, but not with MTH in other muscle regions, including the thigh. Although HbA1c and the number of MetS risk factors in the SO group were significantly higher than those in the GO group, there were no significant differences between GO and SO groups as defined by SMI. Ultrasound-derived abdominal MTH would allow a better assessment of sarcopenia in obese patients and can be used as an alternative to the conventionally-used SMI measured by DXA.

    Development and implementation of a strategy to use a stereotactic ultrasound (US)-based image-guided targeting device (BAT) to align intensity-modulated radiotherapy (IMRT) target volumes accurately in the upper abdomen. Because the outlines of such targets may be poorly visualized by US, we present a method that uses adjacent vascular guidance structures as surrogates for the target position. We assessed the potential for improvement of daily repositioning and the feasibility of daily application. A total of 62 patients were treated by sequential tomotherapeutic IMRT between October 2000 and June 2003 for cholangiocarcinoma and gallbladder carcinoma (n = 10), hepatocellular carcinoma (n = 10), liver metastases (n = 11), pancreatic carcinoma (n = 20), neuroblastoma (n = 3), and other abdominal and retroperitoneal tumors (n = 8). The target volumes (TVs) and organs at risk were delineated in contrast-enhanced CT data sets. Additionally, vascular guidance structures in close anatomic relation to the TV, or within the TV, were delineated. Throughout the course of IMRT, US BAT images were acquired during daily treatment positioning. In addition to the anatomic structures typically used for US targeting (e.g., the TV and dose-limiting organs at risk), CT contours of guidance structures were superimposed onto the real-time acquired axial and sagittal US images, and target position adjustments, as indicated by the system, were performed accordingly. We report the BAT-derived distribution of shifts in the three principal room axes compared with a skin-mark-based setup, as well as the time required to perform BAT alignment. The capability of the presented method to improve target alignment was assessed in 15 patients by comparing the organ and fiducial position between the respective treatment simulation CT with a control CT study after US targeting in the CT suite. A total of 1,337 BAT alignments were attempted. US images were not useful in 56 setups (4.2%), mainly

    The present study investigated group differences between the thickness changes of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles, during performance of the isometric supine chest raise and the supine double leg-straight leg raise tests in women with and without low back pain (LBP). Twenty women with LBP and 20 women without LBP participated in this case-control study. The thickness of the right TrA, IO, and EO muscles was measured using B-mode ultrasound (US) at rest, immediately at the beginning of performing the tests and when participants in both groups self-reported fatigue. The percentage of change in thickness of the abdominal muscles from rest to the initiation and fatigue stages of both tests was measured. The results indicate a statistically significant difference in the pattern of changes in deep (TrA) and superficial (EO) abdominal muscles thickness at the fatigue stage of the supine double straight-leg raise (SDSLR) test between groups (P abdominal muscles thicknesses change at rest or during stages of the clinical isometric endurance tests (P > 0.05). An altered activation pattern in the deep (TrA) and superficial (EO) muscles of LBP participants during fatigue stage of the SDSLR test as compared to controls indicates motor control dysfunction in the LBP group. Comparison of the activity of TrA and EO muscles during fatigue stage of SDSLR test can be used to assess alterations in motor control of abdominal muscles.

    Purpose: Ultrasound is ideal for real-time monitoring in radiotherapy with high soft tissue contrast, non-ionization, portability, and cost effectiveness. Few studies investigated clinical application of real-time ultrasound monitoring for abdominal stereotactic body radiation therapy (SBRT). This study aims to demonstrate the feasibility of real-time monitoring of 3D target motion using 4D ultrasound. Methods: An ultrasound probe holding system was designed to allow clinician to freely move and lock ultrasound probe. For phantom study, an abdominal ultrasound phantom was secured on a 2D programmable respiratory motion stage. One side of the stage was elevated than another side to generate 3D motion. The motion stage made periodic breath-hold movement. Phantom movement tracked by infrared camera was considered as ground truth. For volunteer study three healthy subjects underwent the same setup for abdominal SBRT with active breath control (ABC). 4D ultrasound B-mode images were acquired for both phantom and volunteers for real-time monitoring. 10 breath-hold cycles were monitored for each experiment. For phantom, the target motion tracked by ultrasound was compared with motion tracked by infrared camera. For healthy volunteers, the reproducibility of ABC breath-hold was evaluated. Results: Volunteer study showed the ultrasound system fitted well to the clinical SBRT setup. The reproducibility for 10 breath-holds is less than 2 mm in three directions for all three volunteers. For phantom study the motion between inspiration and expiration captured by camera (ground truth) is 2.35±0.02 mm, 1.28±0.04 mm, 8.85±0.03 mm in LR, AP, SI directly, respectively. The motion monitored by ultrasound is 2.21±0.07 mm, 1.32±0.12mm, 9.10±0.08mm, respectively. The motion monitoring error in any direction is less than 0.5 mm. Conclusion: The volunteer study proved the clinical feasibility of real-time ultrasound monitoring for abdominal SBRT. The phantom and volunteer ABC

    % between ages 3 and 12 months ( and at both ages were lower in infants breast-fed at 3 months than in other infants. US-visceral depths at both 3 and 12 months were inversely related to skinfold thickness at birth ( and at 3 and 12 months, resp.; adjusted for current skinfold thickness. In contrast, US-subcutaneous-abdominal depth at 3 months was positively related to skinfold thickness at birth (. US measures can rank infants with higher or lower IA-AT and SCA-AT. Contrasting patterns of association with visceral and subcutaneous-abdominal adiposities indicate that they may be differentially regulated in infancy.

    Background. The aim of the study was to determine efficacy and reliability of percutaneous abdominal drainage in surgical patients and to evaluate intercostal approach to drain subphrenic collections. Material and methods. Eighty-seven patients aged from 29 to 84 years (mean, 55.5 years) were percutaneously drained under the sonographic guidance due to the postoperative or nonoperated abdominal collection that would otherwise require laparotomy. Intercostal, subcostal, lateral and anterior approach with eight to 14 French catheters were used to evacuate abdominal collection. Results. The intercostal approach was used to drain 31 (60.8%) of 51 subphrenic collections. The mean duration of drainage was independent of the intercostal or subcostal drainage route, but was significantly prolonged (p<0.05, Mann-Whitney U test) for purulent collections (median, 18 days; range 7-73 days) in comparison to hematomas, bilomas and other nonpurulent collections (median, 11 and 6 days, respectively). Sonographically guided percutaneous drainage was a definitive method in 92% patients, with 9.2% minor complications. Successful rate for subphrenic collections was even greater (96%). Conclusions. Sonographically guided percutaneous drainage is the method of choice in the treatment of abdominal collections that require laparotomy. If the puncture site is at least two intercostal spaces lower than the dome of diaphragm and catheter is not introduced through the pleural effusion, intercostal drainage is equally efficient and not less secure than subcostal approach.

    Rehabilitative ultrasound imaging has a great potential to be used as a tool in the assessment of trunk muscle function in patients with low back pain (LBP). However, a further investigation of the discriminative ability of this tool as well as the effect of operators' levels of training on reliability is warranted. Discriminative analysis of ultrasound and electromyography (EMG) measurements of transversus abdominus (TrA), obliquus internus (OI), and obliquus externus (OE) muscles function between people with and without LBP and the effect of operator's training on reliability of TrA muscle function of chronic LBP patients were conducted. For the discriminative study, measurements were collected from 10 subjects with LBP and 10 matched controls during isometric low load tasks with their limbs suspended. For the reliability study, in stage 1 the reliability of single ultrasonographic static images involved 4 operators (1 trained and 3 non-trained), whereas, in stage 2, two operators (1 trained and 1 non-trained) were used to determine the reliability of TrA thickness change. Methods used in the statistical analysis were pearson correlation and receiver operating characteristic curve for the discriminative study and intraclass correlation coefficient (ICC) for the reliability study. While ultrasound measures of OE muscle function showed poor association with EMG (r = 0.28, p = 0.22), TrA and OI function showed moderate to excellent association (TrA: r = 0.74, p Ultrasound and EMG measures of TrA and OI function discriminated LBP patients from controls. Reliability of the assessment of TrA function with a trained operator (ICC = 0.92; 95% CI: 0.81-0.97) was substantially higher than a non-trained one (ICC = 0.44; 95% CI: -0.41-0.78). In conclusion, ultrasound measures of deep trunk function is a valid discriminative tool in LBP but highly dependent on operator's level of training. Copyright © 2011 Elsevier Ltd.

    Hepatic complications contribute to morbidity and mortality after allogeneic hemopoietic SCT. Liver Doppler ultrasound and elastography represent promising methods for pretransplant risk assessment and early detection of complications. Ultrasound (liver and spleen size, liver perfusion) and elastography (transient elastography (TE); right liver lobe acoustic radiation force impulse imaging (r-ARFI); left liver lobe ARFI (l-ARFI)) were prospectively evaluated in patients with indications for allo-SCT. Measurements were performed before and repeatedly after SCT. Results were compared with the incidence of life-threatening complications and death during the first 150 days after SCT. Of 59 included patients, 16 suffered from major complications and 9 of them died within the follow-up period. At baseline, liver and spleen size, liver perfusion, TE and r-ARFI did not differ significantly between patients with and without severe complications. In contrast, l-ARFI was significantly elevated in patients who later developed severe complications (1.58±0.30 m/s vs 1.37±0.27 m/s, P=0.030). After SCT, l-ARFI values remained elevated and TE showed increasing liver stiffness in patients with complications. The value of conventional liver ultrasound for prediction of severe SCT complications is limited. Increased values for TE and l-ARFI are associated with severe SCT complications and demand further evaluation.

    Background: The purpose of this study was to evaluate the accuracy of high-resolution ultrasound (US) with graded compression in the diagnosis of pediatric appendicitis.Material/Methods: The medical records of 664 consecutive children with acute abdominal pain treated between 2007 and 2009 were reviewed retrospectively and analyzed; 408 children (61.4 %) underwent appendectomy and 256 patients were treated conservatively (38.6 %). High-resolution US was performed in 570 out of 664 patients (85.8 %). The US data were verified by intraoperative findings or by clinical follow-up. Results: Out of 664 children, 408 underwent appendectomy and 256 were treated conservatively. US was performed in 570 out of 664 children (85.8 %); in 327/408 children (80.1 %) with AA and in 243/256 children (94.9 %) with negative diagnosis. The sensitivity and specificity for US was 66.6% and 77.4%, respectively. If histopathological diagnosis of catarrhal appendicitis was considered a negative (unnecessary) appendectomy, the sensitivity was 68.6 % (p=0.87), and specificity was 67 % (p=0.29). Positive and negative predictive values of US were 79.9 % and 63.1 %, respectively. After recalculating results, positive predictive value decreased to 59.8% (p=0.036) and negative predictive value increased to 74.8 % (p=0.2). The rate of false negative results was 13.1 % (75/572) and the rate of false positives was 19.2 % (110/572). The negative appendectomy rate was 27.4 % (112/408). Conclusions: High-resolution ultrasonography provides an accurate and specific test for acute appendicitis and is recommended by the authors as an examination of choice in children with acute abdominal pain.

    Wave Intensity Analysis (WIA) can provide parameters representative of the interaction between the vascular network and the heart. It has been already demonstrated that WIA-derived biomarkes have a quantitative physiological meaning. Aim of this study was to develop an image process algorithm for performing non-invasive WIA in mice and correlate commonly used cardiac function parameters with WIA-derived indexes. Sixteen wild-type male mice (8 weeks-old) were imaged with high-resolution ultrasound (Vevo 2100). Abdominal aorta and common carotid pulse wave velocities (PWVabd, PWVcar) were obtained processing B-Mode and PW-Doppler images and employed to assess WIA. Amplitudes of the first (W1abd, W1car) and the second (W2abd, W2car) local maxima and minimum (Wbabd,Wbcar) were evaluated; areas under the negative part of the curve were also calculated (NAabd, NAcar). Cardiac output (CO), ejection fraction (EF) fractional shortening (FS) and stroke volume (SV) were estimated; strain analysis provided strain and strain rate values for longitudinal, radial and circumferential directions (LS, LSR, RS, RSR, CS, CSR). Isovolumetric relaxation time (IVRT) was calculated from mitral inflow PW-Doppler images; IVRT values were normalized for cardiac cycle length. W1abd was correlated with LS (R=0.65) and LSR (R=0.59), while W1car was correlated with CO (R=0.58), EF (R=0.72), LS (R=0.65), LSR (R=0.89), CS (R=0.71), CSR (R=0.70). Both W2abd and W2car were not correlated with IVRT. Carotid artery WIA-derived parameters are more representative of cardiac function than those obtained from the abdominal aorta. The described US-based method can provide information about cardiac function and cardio-vascular interaction simply studying a single vascular site.

    The adipose tissue metabolism is dependent on its blood perfusion. During lipid mobilization e.g. during exercise and during lipid deposition e.g. postprandial, adipose tissue blood flow is increased. This increase in blood flow may involve capillary recruitment in the tissue. We investigated...... of ultrasound contrast agent to establish the reproducibility of the technique. In nine subjects, the effect of an oral glucose load on blood flow and microvascular volume was measured in abdominal subcutaneous adipose tissue and forearm skeletal muscle. ¹³³Xe washout and venous occlusion strain......-gauge plethysmography was used to measure the adipose tissue and forearm blood flow, respectively. Ultrasound signal intensity of the first plateau phases was 27 ± dB in the abdominal subcutaneous adipose tissue and 18 ± 2 dB (P

    Full Text Available Gastrointestinal perforation is a serious adverse event that occurs in approximately 1% of patients receiving ramucirumab and paclitaxel. A 67-year-old man with unresectable advanced gastric cancer was admitted to our hospital and treated with ramucirumab and paclitaxel. Gastric perforation occurred during the second cycle of chemotherapy. Although the patient’s condition improved without surgery, an abscess developed in the intra-abdominal fluid collection resulting from the perforation. We performed endoscopic ultrasound-guided abscess drainage. The patient improved and was discharged in satisfactory condition. Endoscopic ultrasound-guided drainage is a treatment option for patients with intra-abdominal abscess following gastric perforation due to ramucirumab.

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

    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.

    AIM: To retrospectively evaluate the prevalence of lymph nodes of the hepato-duodenal ligament in a group of patients with chronic liver disease of various aetiologies and to investigate what clinical, aetiological and laboratory data may lead to their appearance. MATERIALS AND METHODS: One thousand and three patients (554 men, 449 women) were studied, including 557 with chronic hepatitis and 446 with liver cirrhosis. The presence of lymph nodes near the trunk of the portal vein, hepatic artery, celiac axis, superior mesenteric vein and pancreas head was investigated using ultrasound. RESULTS: Lymph nodes were detected in 394 out of the 1003 study patients (39.3%); their number ranged from one to four, with a diameter ranging between 0.8 and 4 cm. The highest prevalence was in the subgroup of patients with primary biliary cirrhosis (87.5%), followed by patients with hepatitis C virus (HCV; 42%), patients with HCV and hepatitis B virus (HBV; 41.3%), autoimmune hepatitis (40%), and HBV alone (21.2%). In the alcoholic and idiopathic subgroups prevalence was 9.5%, while in the non-alcoholic steatohepatitis and haemochromatosis subgroups it was 0%. HCV RNA was present in 97 out of 103 lymph node-positive patients and in 141 out of 168 lymph node-negative HCV-negative patients (p<0.003). Lymphadenopathy frequency increased as the liver disease worsened ({chi}{sup 2} MH=74.3; p<0.0001). CONCLUSION: Despite the limitations of a retrospective study, our data indicate a high prevalence of lymphadenopathy in liver disease patients; ultrasound evidence of lymph nodes of the hepato-duodenal ligament in a given liver disease may most likely suggest a HCV or an autoimmune aetiology and a more severe histological picture.

    Transversus abdominis plane (TAP) block used for management of surgical abdominal pain by injecting local anesthetics into the plane between the internal oblique and transversus abdominis muscles. We aimed to explore the effect of adding morphine to bupivacaine in ultrasound guided TAP-block in patients undergoing lower abdominal cancer surgery. Randomized, double-blind, prospective study. Clinical trial identifier: NCT02566096. Academic medical center. Sixty patients were enrolled in this study after ethical committee approval. Patients divided into 2 groups (30 each): Bupivacaine group (GB): given ultrasound guided TAP-block 20ml 0.5% bupivacaine diluted in 20ml saline; Morphine group (GM): given ultrasound guided TAP-block with 20ml 0.5% bupivacaine+10mg morphine sulphate diluted in 20ml saline. Patients were observed for total morphine consumption, time for first request of rescue analgesia, sedation scores, hemodynamics and side effects for 24h postoperatively. Morphine added to bupivacaine in TAP block compared to bupivacaine alone reduced total morphine consumption (5.33±1.28mg) (10.70±3.09mg) respectively (p0.05). Addition of morphine to bupivacaine in TAP block is effective method for pain management in patients undergoing major abdominal cancer surgery without serious side effects.

    OBJECTIVE We sought to compare fundal height and handheld ultrasound–measured fetal abdominal circumference (HHAC) for the prediction of fetal growth restriction (FGR) or large for gestational age. STUDY DESIGN This was a diagnostic accuracy study in nonanomalous singleton pregnancies between 24 and 40 weeks’ gestation. Patients underwent HHAC and fundal height measurement prior to formal growth ultrasound. FGR was defined as estimated fetal weight less than 10%, whereas large for gestational age was defined as estimated fetal weight greater than 90%. Sensitivity and specificity were calculated and compared using methods described elsewhere. RESULTS There were 251 patients included in this study. HHAC had superior sensitivity and specificity for the detection of FGR (sensitivity, 100% vs 42.86%) and (specificity, 92.62% vs 85.24%). HHAC had higher specificity but lower sensitivity when screening for LGA (specificity, 85.66% vs 66.39%) and (sensitivity, 57.14% vs 71.43%). CONCLUSION HHAC could prove to be a valuable screening tool in the detection of FGR. Further studies are needed in a larger population. PMID:25818672

    To assess the diagnostic value of ultrasound compared to CT in evaluating acute abdominal pain of different causes in children 10 years of age and under, hospital records and imaging files of 4052 patients under age of 10 who had imaging for abdominal pain were reviewed. One-hundred-thirty-two patients (3 %), (74 males/58 females) who underwent ultrasound and CT within 24 h were divided by age: group I, ages 0-48 months (25 patients); group II, 49-84 months (53 patients); and group III, 85-120 months (54 patients). Diagnoses at ultrasound, CT, and discharge were compared. Cases of a change in diagnosis following CT and impact of the changed diagnosis on patient management were assessed. Non-diagnostic ultrasound or a diagnostic conundrum was present in a small percentage (3 %) of our patients. In the group of patients imaged with two modalities, CT changed the diagnosis in 73/132 patients (55.3 %). Patient management changed in 63/132 patients (47.7 %). CT changed the diagnosis in 46/64 patients with surgical conditions (71.8 %, p diagnostic or equivocal US in a small percentage of patients is probably sufficient to justify the additional radiation burden.

    Test-retest reliability of the combined process of ultrasound imaging (USI) and image measurement of thickness of abdominal and upper lumbar multifidus (MF) muscles and MF cross sectional area (CSA) of older adults has not been established. Imaging muscles of older adults can be challenging due to age-related changes in the spine and skeletal muscle so establishing test-retest reliability in this population is important. This study aimed to evaluate test-retest reliability of USI of abdominal and MF muscle thickness and MF CSA for adults aged 50-79 years. One operator took single sets of ultrasound images of abdominal and MF muscles of 23 adults aged 50-79 years participating in a clinical trial of vitamin D supplementation for knee osteoarthritis, on two occasions, one week apart. Images were subsequently measured by a single examiner. Test-retest reliability for abdominal muscle thickness and MF CSA was substantial (intraclass correlation coefficients (ICC) > 0.81) and for MF thickness ranged from fair to substantial (ICC 0.55-0.86). The standard error of measurement (SEM) was low (0.02-0.21) in every case. ICCs were low and SEM values were high for percentage thickness change. The substantial test-retest reliability of abdominal and MF (L4-L5) muscle thickness and of MF CSA supports the use of USI as a clinical and research tool to assess abdominal and MF muscle thickness and MF CSA of older adults.

    It is hypothesized that the degree of vascularization of the thrombus may have a significant impact on the rupture of aortic aneurysms. The presence of neovascularization of the vessel wall and mural thrombus has been confirmed only in histopathological studies. However, no non-invasive imaging technique of qualitative assessment of thrombus and neovascularization has been implemented so far. Contrast-enhanced ultrasound (CEUS) has been proposed as a feasible and minimally invasive technique for in vivo visualization of neovascularization in the evaluation of tumors and atherosclerotic plaques. The aim of this study was the evaluation of mural thrombus and AAAs wall with CEUS. CEUS was performed in a group of seventeen patients with AAAs. The mural thrombus enhancement was recognized in 12 cases, yet no significant correlation between the degree of contrast enhancement and AAAs diameter, thrombus width, and thrombus echogenicity was found. We observed a rise in AAAs thrombus heterogeneity with the increase in the aneurysm diameter (r = 0.62, p = 0.017). In conclusion CEUS can visualize small channels within AAAs thrombus, which could be a result of an ongoing angiogenesis. There is a need for further research to find out whether the degree of vascularization of the thrombus may have a significant impact on the rupture of aneurysms.

    Endoscopy is currently the primary diagnostic technique for inflammatory bowel disease (IBD) in children. To assess the accuracy of US and dynamic contrast-enhanced MRI for diagnosing inflammatory bowel disease and for distinguishing Crohn disease and ulcerative colitis in comparison to a reference standard. Consecutive children with suspected IBD underwent diagnostic workup including ileocolonoscopy and upper gastrointestinal endoscopy as the reference standard, abdominal US, and MR enterography and colonography at 3 T. The protocol included a dynamic contrast-enhanced 3-D sequence. Sensitivity, specificity and kappa values were calculated for one ultrasonographer and two MRI observers. We included 28 children (15 boys) with mean age 14 years (range 10-17 years). The diagnosis was IBD in 23 children (72%), including 12 with Crohn disease, 10 with ulcerative colitis and 1 with indeterminate colitis. For the diagnosis of inflammatory bowel disease the sensitivity was 55% for US and 57% (both observers) for MR entero- and colonography, and the specificity was 100% for US and 100% (observer 1) and 75% (observer 2) for MR entero- and colonography. Combined MRI and US had sensitivity and specificity of 70% and 100% (observer 1) and 74% and 80% (observer 2), respectively. With the addition of a dynamic contrast-enhanced MR sequence, the sensitivity increased to 83% and 87%. US and MRI could only distinguish between Crohn disease and ulcerative colitis when terminal ileum lesions were present. US and MR entero- and colonography have a high accuracy for diagnosing inflammatory bowel disease in children but cannot be used to distinguish Crohn disease and ulcerative colitis. (orig.)

    Abdominal aortic aneurysms (AAA) are a degenerative disease of the human aortic wall that may lead to weakening and eventually rupture of the wall with high mortality rates. Since the currently established criterion for surgical or endovascular treatment of the disease is imprecise in the individual case and treatment is not free of complications, the need for additional patient-individual biomarkers for short-term AAA rupture risk as basis for improved clinical decision making. Time resolved 3D ultrasound combined with speckle tracking algorithms is a novel non-invasive medical imaging technique that provides full-field displacement and strain measurements of aortic and aneurysmal wall motion. This is patient-individual information that has not been used so far to assess wall strength and rupture risk. The current study uses simple statistical indices of the heterogeneous spatial distribution of in-plane strain components as biomarkers for the pathological state of the aortic and aneurysmal wall. The pathophysiological rationale behind this approach are the known changes in microstructural composition of the aortic wall with progression of AAA development that results in increased stiffening and heterogeneity of the walls mechanical properties and in decreased wall strength. In a comparative analysis of the aortic wall motion of young volunteers without known cardiovascular diseases, aged arteriosclerotic patients without AAA, and AAA patients, mean values of all in-plane strain components were significantly reduced, and the heterogeneity of circumferential strain was significantly increased in the AAA group compared to both other groups. The capacity of the proposed method to differentiate between wall motion of aged, arteriosclerotic patients and AAA patients is a promising step towards a new method for in vivo assessment of AAA wall strength or stratification of AAA rupture risk as basis for improved clinical decision making on surgical or endovascular

    Full Text Available It needs to be emphasized that ultrasonography is a primary test performed in order to evaluate the abdominal wall and structures located in their vicinity. It allows for the determination of the anatomy and lesions in this localization. Thorough knowledge con‑ cerning the ultrasound anatomy of the tested structures constitutes a basis of all diagnos‑ tic successes. Therefore, this part of the article is devoted to this subject matter. The pos‑ sibility to diagnose intra-abdominal adhesions with ultrasound is underestimated and rarely used. The aim of this paper is to discuss and document the ultrasound anatomy of the posterior surface of the abdominal wall as well as to present techniques directed at the detection of adhesions, in particular the visceroperitoneal ones. The posterior surface of the abdominal wall constitutes an extensive tissue area of complex structure, with folds and ligaments surrounded by various amounts of the epiperitoneal fat. In some places, this tissue separates the components of the fascia and peritoneum complex. The ultra‑ sound manifestation of this complex is two hyperechogenic lines placed parallelly to each other in the places where they are not separated by the accumulated adipose tissue. Another factor which separates the peritoneum from the viscera is of dynamic character. It is a so-called visceral slide induced by easy or deep breathing. Its size should not be lower than 1 cm and the deflections gradually and symmetrically diminish from the epi‑ gastric to hypogastric region. Last but not least, the evaluation of the reciprocal relation of the abdominal wall with viscera may be aided by rhythmical manual compressions on the abdominal wall (ballottement sign performed below the applied ultrasound trans‑ ducer. During this test, the size of the visceral slide in relation to the abdominal wall is observed. The maneuver is usually performed in uncooperative patients or those with shallow breath. The

    Abdominal obesity is recognized as the main reason of metabolic syndrome, which is closely related to disordered skeletal and/or abdominal muscle metabolic functions. Metabolomics is a comprehensive assessment system in biological metabolites. The aim of our present study is to investigate the diet-induced metabolic risk factors by metabolic in the abdominal muscles and clarify the relationship between atheroprotective effects of Resveratrol (Rev) and abdominal muscles metabolic components during the development of atherosclerosis. The mice were randomly divided into three groups including normal group (N), high fat diet (HFD or H) group and high fat diet with Rev treated group (HR). GC-MS combined with pattern recognition approaches were employed to obtain comprehensive metabolic signatures and related differential metabolites after 24 week HFD feeding. Oil Red O staining and Electron microscopy technology (EMT) were employed to detect the size of fatty plaques and intracellular lipid accumulation, respectively. The result indicated that 22 types of metabolites in the abdominal muscles were obviously altered by HFD feeding group. Moreover, Rev treatment obviously increased 11 different kinds of metabolites, most of which were involved in the carbohydrate, amino acid and lipid metabolisms. Importantly, these elevated different metabolites were involved in pathways mainly related to galactose metabolism, alanine, aspartate and glutamate metabolism, glyoxylate and dicarboxylate metabolism in abdominal muscles. Oil Red O staining and Electron microscopy showed less lipid accumulation in the lesions and decreased intracellular lipid deposition in the foam cells in HR group. We concluded that Rev produced a beneficial effect partially by modulating multiple metabolism pathways and metabolites in the abdominal muscles, which may provide a new protective mechanism of Rev on the progression of atherosclerosis. These notably changed metabolites might be potential biomarkers

    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

    Ultrasonography imaging has been used as a non-invasive method to estimate the thickness and relative activities of the abdominal muscles in patients with lower back pain (LBP). However, the statistical reliability of US thickness measurements of abdominal muscles, including transversus abdominis (TrA), internal oblique (IO) and external oblique (EO) muscles during abdominal hollowing (AH) and abdominal bracing (AB) maneuvers has not been well-investigated. This study was performed on a total of 20 female subjects (10 with LBP and 10 without LBP) in the age range of 25-55 years to assess within-day and between-day reliability of the measurements. US measurements on maneuvers were repeated after two hours for the within-day reliability and after five days for the between-day reliability assessment. High intra-class correlation coefficient (ICC) values (>0.75) for within-day and between-day reliability assessments during AH maneuver were concluded. The ICC values were moderate for reliability assessment during AB. The ICC values for AH were greater than AB both for within- and between-day reliabilities. The small standard error of measurement and minimal detectable change values (0.16-0.78 and 0.44 to 2.15, respectively) were found for both AH and AB. We recommend real-time US imaging as a reliable way of determining the thicknesses of the TrA and IO muscle (and to some extent, EO muscle) for both healthy and LBP patients.

    Activity of deep abdominal muscles increases the lumbar stability. Majority of previous studies indicated abdominal muscle activity dysfunction during static activity in patients with low back pain (LBP). However, the number of studies that evaluated deep abdominal muscle activity in dynamic standing activities in patients is limited, while this assessment provides better understanding of pain behavior during these activities. Investigation of superficial and deep abdominal muscles activity in participants with chronic LBP as compared to healthy individuals during standing tasks. Case control study. Ultrasound imaging was used to measure the thickness of transverse abdominis (TrA), internal oblique (IO) and external oblique (EO) muscles in female participants with (N = 45) and without chronic LBP (CLBP) (N = 45) during tests. The Biodex Balance System was used to provide standing tasks. The thickness of each muscle in a standing task was normalized to actual thickness at rest in the supine lying position to estimate its activity. The results indicate increases in thickness of all muscles in both groups during dynamic as compared to static standing tasks (P  0.5). Lower percentages of thickness change for TrA muscle and higher for EO muscle were found in the patients as compared to healthy individuals during all tests (P  1.28).

    Ultrasound (US) measures are used by clinicians and researchers to evaluate improvements in activity of the abdominal muscles in patients with low back pain. Studies evaluating the reproducibility of these US measures provide some information; however, little is known about the reproducibility of these US measures over time in patients with low back pain. The objectives of this study were to estimate the reproducibility of ultrasound measurements of automatic activation of the lateral abdominal wall muscles using a leg force task in patients with chronic low back pain. Thirty-five participants from an existing randomised, blinded, placebo-controlled trial participated in the study. A reproducibility analysis was undertaken from all patients using data collected at baseline and after treatment. The reproducibility of measurements of thickness, muscle activation (thickness changes) and muscle improvement/deterioration after intervention (differences in thickness changes from single images made before and after treatment) was analysed. The reproducibility of static images (thickness) was excellent (ICC2,1 = 0.97, 95% CI = 0.96–0.97, standard error of the measurement (SEM) = 0.04 cm, smallest detectable change (SDC) = 0.11 cm), the reproducibility of thickness changes was moderate (ICC2,1 = 0.72, 95% CI 0.65–0.76, SEM = 15%, SDC 41%), while the reproducibility of differences in thickness changes from single images with statistical adjustment for duplicate measures was poor (ICC2,1 = 0.44, 95% CI 0.33–0.58, SEM = 21%, SDC = 66.5%). Improvements in the testing protocol must be performed in order to enhance reproducibility of US as an outcome measure for abdominal muscle activation. PMID:19415347

    Background and purpose: We investigated whether corrective shifts determined by daily ultrasound-based image-guidance correlate with body mass index (BMI) of patients treated with image-guided intensity-modulated radiation therapy (IG-IMRT) for abdominal malignancies. The utility of daily image-guidance, particularly for patients with BMI > 25.0, is examined. Materials and methods: Total 3162 ultrasound-directed shifts were performed in 86 patients. Direction and magnitude of shifts were correlated with pretreatment BMI. Bivariate statistical analysis and analysis of set-up correction data were performed using systematic and random error calculations. Results: Total 2040 daily alignments were performed. Average 3D vector of set-up correction for all patients was 12.1 mm/fraction. Directional and absolute shifts and 3D vector length were significantly different between BMI cohorts. 3D displacement averaged 4.9 mm/fraction and 6.8mm/fraction for BMI ≤ 25.0 and BMI > 25.0, respectively. Systematic error in all axes and 3D vector was significantly greater for BMI > 25.0. Differences in random error were not statistically significant. Conclusions: Set-up corrections derived from daily ultrasound-based IG-IMRT of abdominal tumors correlated with BMI. Daily image-guidance may improve precision of IMRT delivery with benefits assessed for the entire population, particularly patients with increased habitus. Requisite PTV margins suggested in the absence of daily image-guidance are significantly greater in patients with BMI > 25.0.

    Longitudinal single-cohort study. Athletes with longstanding groin pain associated with resisted hip adduction have been shown to have abnormal activation of the transversus abdominis (TA). Therefore, exercises targeting the TA to help stabilize the lumbopelvic area are generally used in the rehabilitation of these athletes. To investigate if (1) changes in abdominal muscle resting thickness and changes in relative thickness during lower extremity tasks after 14 weeks of intervention are related to changes in clinical status and (2) the changes in abdominal muscle resting/relative thickness are significant postintervention. In 21 athletes with longstanding groin pain associated with resisted hip adduction, ultrasound imaging of the abdominal musculature on the right side was performed at rest, during the active straight-leg raise (left and right), and during bilateral isometric hip adduction. Athletes then followed a 14-week rehabilitation protocol. Clinical outcome measured by self-reported sports restriction and change in abdominal muscle resting and relative thickness during lower extremity tasks were evaluated. There was an overall significant decrease in self-reported sports restriction after intervention for this group of athletes. Apart from a significant negative correlation for changes in TA resting thickness, no significant association between changes in abdominal muscle thickness and change in self-reported sports restriction were found. Postintervention, TA resting thickness was significantly increased but relative thickness during the lower extremity tasks was found not to be statistically different for all muscles, except for a decreased relative thickness of obliquus externus abdominus (OE) during the active straight-leg raise for the left lower extremity. There was no association between changes in abdominal muscle resting thickness and relative thickness during lower extremity tasks, and change in self-reported sports restriction after a period of

    There is a controversy regarding whether core stability exercise (CSE) is more effective than general exercise (GE) for chronic LBP. To compare different exercises regarding their effect on improving back strength and stability, performance of abdominal muscles is a useful index. Ultrasound imaging for measuring muscle thickness could be used to assess muscle performance. The aim of this study was to compare CSE and GE in chronic LBP using ultrasound imaging for measurement of thickness of the deep stabilizing and main global trunk muscles in non-specific chronic LBP. Each program included 16 training sessions three times a week. Using ultrasound imaging, four transabdominal muscle thickness were measured before and after the intervention. Disability and pain were measured as secondary outcomes. After the intervention on participants (n = 43), a significant increase in muscle thickness (hypertrophy) was seen only in right and left rectus abdominis in the GE group, but significant difference to the CSE group was only on the right side. Disability and pain reduced within the groups without a significant difference in the change between them. The present results provided evidence that only GE increased right and left rectus muscle thickness. The only significant difference between CSE and GE groups was the right rectus thickness. As rectus is a global muscle, the effect of GE on strength improvement (one side stronger than the other) may have a negative effect on motor control of lumbopelvic muscles and possibly increase the risk of back pain occurring or becoming worse, though this was not observed in the present study.

    Purpose: The aim of this study was to compare CT findings of adrenal incidentalomas with a definitive histological diagnosis in order to establish CT features characteristic for individual types of lesions. Patients and methods: The retrospective study comprised of patients with adrenal lesions detected on abdominal CT. The patients with these incidental findings subsequently underwent adrenalectomy. The adrenalectomy was followed by a histological assessment of the expansion process. The study consisted of 62 adrenal expansions found in 55 patients (in seven patients bilateral lesions were found). According to the definitive histological diagnosis after adrenalectomy, the lesions were divided into the following six groups: primary adrenocortical carcinoma (n = 4), metastasis (n = 7), adrenocortical adenoma (n = 37), pheochromocytoma (n = 9), myelolipoma (n = 2), and others (n = 3). CT observations were categorized as follows: size, shape, margins, density, side of the expansion, homogeneous or heterogeneous density before and after contrast application, presence of central hypodensity, presence of central calcifications and fat deposits. Statistical analysis was carried out using the χ 2 -test, Kruskal-Wallis test and Mann-Whitney test. To estimate the differences between the subgroups, the t-test was used. For the evaluation of the mutual relations of maximum size, mean size, and volume, regression analysis (coefficient of determination R 2 ) was used. Results: The correlation and regression analysis suggest that there will be no statistically significant error if the maximum size measurements are used instead of the mean size or volume measurements of the lesion. Sensitivity, specificity, accuracy, positive predictive value, negative predictive value for distinguishing adenomas and non-adenomas using a cut-off diameter of 41.5 mm were 81.1%, 70.0%, 77.2%, 83.3%, 66.7%, respectively; using the non-contrast density threshold of 23 HU, they were 89.2%, 100%, 93

    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%).

    Full Text Available Background: Regional anesthetic techniques can be used to alleviate postoperative pain in patients undergoing major upper abdominal surgery. Our aim was to evaluate the efficacy of bilateral ultrasound (US-guided rectus sheath (RS and transversus abdominis plane (TAP blocks for better perioperative analgesia. Patients and Methods: It is a prospective, observer-blinded, randomized clinical study. 40 eligible patients undergoing elective liver resection or Whipple procedure were included. All patients received a standardized anesthetic technique. Group 1 (n = 20 received preincisional US-guided bilateral RS and TAP blocks using 20 ml volume of bupivacaine 0.25% for each, and group 2 (n = 20 received local wound infiltration at end of surgery with 40 ml of bupivacaine 0.25%. A standardized postoperative analgesic regimen composed of intravenous paracetamol and a morphine patient-controlled analgesia (PCA. The use of intraoperative fentanyl and recovery room morphine boluses, PCA-administered morphine, pain scores as well as number of patients′ experienced postoperative nausea and vomiting in the ward at 6 and 24 h were recorded. Results: Group 1 patients received a significantly lower cumulative intraoperative fentanyl, significantly lesser boluses of morphine in postanesthesia care unit, as well, significantly lower cumulative 24 h postoperative morphine dosage than the group 2 patients. Pain visual analog scale scores were significantly lower at both 6 and 24 h postoperatively in TAP group when compared with the no-TAP group. There were no complications related to the TAP block procedures. No signs or symptoms of local anesthetic systemic toxicity were detected. Conclusion: The combination of bilateral US-guided RS and TAP blocks provides excellent perioperative analgesia for major upper abdominal surgery.

    Full Text Available The aim of the present study was the ultrasound characterization of the abdominal and pelvic regions of five maned wolves kept in captivity at the Triage Center of Wild Animals of the Federal University of Viçosa (Centro de Triagem de Animais Silvestres, Universidade Federal de Viçosa. This characterization included descriptions of ultrasonographic aspects and measurements of various structures using B-mode ultrasound. Biometric data were collected to assess the existence of significant linear correlations between these measurements and the measurements obtained by ultrasound. Additionally, hematological and serum biochemistry evaluations of the animals were performed. The ultrasound findings were similar to those available in the literature on domestic dogs, which were used for comparison as a result of the lack of published data regarding maned wolves. The latter species showed characteristics closely resembling those of the former, differing in the spleen and left renal cortex echogenicities, in the appearance of the prostatic and testicular regions and in the hepatic portal vein morphology. In the current study, the biometric values were similar to those previously published; however, no data regarding thoracic perimeter, modified crown-rump length or thoracic depth were found in the literature for this Canidae species. Statistical analysis showed the existence of a strong negative correlation between the modified crown-rump length and left renal length, between the modified crown-rump length and the right renal volume, between the thoracic perimeter and the height at the cranial pole of the left adrenal gland and between the thoracic perimeter and the height at the caudal pole of the left adrenal gland.

    Ultrasound plays a pivotal role in the evaluation of acute trauma patients through the use of multi-site scanning encompassing abdominal, cardiothoracic, vascular and skeletal scans. In a high-speed polytrauma setting, because exsanguinations are the primary cause of trauma morbidity and mortality, ultrasound is used for quick and accurate detection of hemorrhages in the pericardial, pleural, and peritoneal cavities during the primary Advanced Trauma Life Support (ATLS) survey. Volume status can be assessed non-invasively with ultrasound of the inferior vena cava (IVC), which is a useful tool in the initial phase and follow-up evaluations. Pneumothorax can also be quickly detected with ultrasound. During the secondary survey and in patients sustaining low-speed or localized trauma, ultrasound can be used to help detect abdominal organ injuries. This is particularly helpful in patients in whom hemoperitoneum is not identified on an initial scan because findings of organ injuries will expedite the next test, often computed tomography (CT). Moreover, ultrasound can assist in detection of fractures easily obscured on radiography, such as rib and sternal fractures. Copyright © 2015 World Federation for Ultrasound in Medicine & Biology.

    Many institutions now use empiric full-body computed tomography (CT) as a standard step in the initial workup of stable trauma patients. Recent data suggest that these scans may reveal unexpected injuries and improve survival in patients with polytrauma. However, patients who are unstable on presentation are often taken to the operating room (OR) without CT. Many of these patients undergo empiric full-body CTs after being stabilized in the OR, yet few data exist regarding how often early postoperative CT reveals unexpected injuries within compartments that have been explored surgically. Thus, the objective of this study was to determine if empiric abdominal/pelvic (ABD) CT after emergent trauma laparotomies are likely to reveal missed injuries requiring urgent management and improve patient management compared with clinical judgment alone. We review retrospectively 496 trauma patients who required urgent exploratory laparotomy at UPMC Presbyterian Hospital from 2007 to 2011. Patients were included if they went to the OR for exploratory laparotomy directly from the emergency department within 2 hours of arrival. Patients were excluded if they received any preoperative ABD CT imaging. Patients who expired in the OR were similarly excluded. Patients were stratified into 2 groups based on whether or not they received an empiric ABD CT in the 24 hours immediately after laparotomy. Medical records were reviewed to look for differences in missed injuries, urgent reexplorations, nontherapeutic interventions, and time to urgent reexploration. There were 278 patients who met inclusion at exclusion criteria and constituted the study cohort. Of these patients, 124 underwent early empiric postoperative ABD CT imaging (45%). The remaining 154 patients did not undergo early ABD imaging (no CT group). The overall cohort had a 45% incidence of damage control procedures and a 9% rate of negative laparotomy. The 2 groups were statistically similar in age, presenting vitals, and

This condition should be distinguished from pulmonary complications that require treatment. OBJECTIVE: To prospectively determine the incidence of pleural effusion in patients submitted to elective abdominal surgery using ultrasound (US, and to assess the possible association with risk factors related to the patients and anesthetic-surgical procedures. MATERIALS AND METHODS: Thirty-seven patients, 21 (56.8% female, and 16 (43.2% male aged 29 to 76 years submitted to elective abdominal surgery were evaluated. US was performed preoperatively and 48 hours after surgery in all patients. Associated risk factors were also assessed - age > 60 years, sex, obesity, smoking history, alcoholism and associated diseases -, and anesthetic-surgical procedure - cancer resection, class ASA > 2, duration of surgery, longitudinal incision and incision > 15 cm. Biliar lithiasis (43.2% and gastrointestinal cancer (43.2% were the main causes leading to surgery. RESULTS: The incidence of postoperative pleural effusion (PPE detected by US was 70.3% (26/37. Two of these patients (5.4% developed pulmonary complications, and one died. The risk factors age > 60 years, smoking history, alcoholism, obesity and associated diseases had no influence on the development of the PPE whereas cancer resection, class ASA > 2, longitudinal incision and incision > 15 cm were significantly statistically associated with the presence of PPE. PPE developed even during antibiotic therapy. The duration of hospitalization was more than 2.4 longer in the patients with PPE. CONCLUSION: PPE is a very frequent condition observed in patients

The cases consisted of patients with CHD admitted for the first time in a pediatric intensive care unit; the controls consisted of children without CHD who underwent AUS at the hospital shortly thereafter a case. All patients with CHD underwent AUS, high-resolution karyotype and fluorescence in situ hybridization (FISH for microdeletion 22q11.2. RESULTS: AUS identified clinically significant abnormalities in 12.2% of the cases and 5.2% of controls (p= 0.009, with a power of significance of 76.6%. Most malformations with clinical significance were renal anomalies (10.4% in cases and 4.9% in controls; p= 0.034. In Brazil, the cost of an AUS examination for the Unified Health System is US$ 21. Since clinically significant abnormalities were observed in one in every 8.2 CHD patients, the cost to identify an affected child was calculated as approximately US$ 176. CONCLUSION: Patients with CHD present a significant frequency of abdominal abnormalities detected by AUS, an inexpensive and noninvasive diagnostic method with good sensitivity. The cost of screening for these defects is considerably lower than the cost to treat the complications of late diagnoses of abdominal malformations such as renal disease.

We performed genome-wide association of abdominal adipose depots quantified using computed tomography (CT to uncover novel loci for body fat distribution among participants of European ancestry. Subcutaneous and visceral fat were quantified in 5,560 women and 4,997 men from 4 population-based studies. Genome-wide genotyping was performed using standard arrays and imputed to ~2.5 million Hapmap SNPs. Each study performed a genome-wide association analysis of subcutaneous adipose tissue (SAT, visceral adipose tissue (VAT, VAT adjusted for body mass index, and VAT/SAT ratio (a metric of the propensity to store fat viscerally as compared to subcutaneously in the overall sample and in women and men separately. A weighted z-score meta-analysis was conducted. For the VAT/SAT ratio, our most significant p-value was rs11118316 at LYPLAL1 gene (p = 3.1 × 10E-09, previously identified in association with waist-hip ratio. For SAT, the most significant SNP was in the FTO gene (p = 5.9 × 10E-08. Given the known gender differences in body fat distribution, we performed sex-specific analyses. Our most significant finding was for VAT in women, rs1659258 near THNSL2 (p = 1.6 × 10-08, but not men (p = 0.75. Validation of this SNP in the GIANT consortium data demonstrated a similar sex-specific pattern, with observed significance in women (p = 0.006 but not men (p = 0.24 for BMI and waist circumference (p = 0.04 [women], p = 0.49 [men]. Finally, we interrogated our data for the 14 recently published loci for body fat distribution (measured by waist-hip ratio adjusted for BMI; associations were observed at 7 of these loci. In contrast, we observed associations at only 7/32 loci previously identified in association with BMI; the majority of overlap was observed with SAT. Genome-wide association for visceral and subcutaneous fat revealed a

    Ultrasound effects on biological samples are gaining a growing interest concerning in particular, the intracellular delivery of drugs and genes in a safe and in a efficient way. Future progress in this field will require a better understanding of how ultrasound and acoustic cavitation affect the biological system properties. The morphological changes of cells due to ultrasound (US) exposure have been extensively studied, while little attention has been given to the cells structural changes. We have exposed two different cell lines to 1 MHz frequency ultrasound currently used in therapy, Jurkat T-lymphocytes and NIH-3T3 fibroblasts, both employed as models respectively in the apoptosis and in the gene therapy studies. The Fourier Transform Infrared (FTIR) Spectroscopy was used as probe to reveal the structural changes in particular molecular groups belonging to the main biological systems. The genotoxic damage of cells exposed to ultrasound was ascertained by the Cytokinesis-Block Micronucleus (CBMN) assay. The FTIR spectroscopy results, combined with multivariate statistical analysis, regarding all cellular components (lipids, proteins, nucleic acids) of the two cell lines, show that Jurkat cells are more sensitive to therapeutic ultrasound in the lipid and protein regions, whereas the NIH-3T3 cells are more sensitive in the nucleic acids region; a meaningful genotoxic effect is present in both cell lines only for long sonication times while in the Jurkat cells also a significant cytotoxic effect is revealed for long times of exposure to ultrasound.

    To evaluate a novel four-dimensional (4D) ultrasound (US) tracking system for external beam radiotherapy of upper abdominal lesions under computer-controlled deep-inspiration breath-hold (DIBH). The tracking accuracy of the research 4D US system was evaluated using two motion phantoms programmed with sinusoidal and breathing patterns to simulate free breathing and DIBH. Clinical performance was evaluated with five healthy volunteers. US datasets were acquired in computer-controlled DIBH with varying angular scanning angles. Tracked structures were renal pelvis (spherical structure) and portal/liver vein branches (non-spherical structure). An external marker was attached to the surface of both phantoms and volunteers as a secondary object to be tracked by an infrared camera for comparison. Phantom measurements showed increased accuracy of US tracking with decreasing scanning range/increasing scanning frequency. The probability of lost tracking was higher for small scanning ranges (43.09% for 10 and 13.54% for 20 ).The tracking success rates in healthy volunteers during DIBH were 93.24 and 89.86% for renal pelvis and portal vein branches, respectively. There was a strong correlation between marker motion and US tracking for the majority of analyzed breath-holds: 84.06 and 88.41% of renal pelvis target results and 82.26 and 91.94% of liver vein target results in anteroposterior and superoinferior directions, respectively; Pearson's correlation coefficient was between 0.71 and 0.99. The US system showed a good tracking performance in 4D motion phantoms. The tracking capability of surrogate structures for upper abdominal lesions in DIBH fulfills clinical requirements. Further investigation in a larger cohort of patients is underway. (orig.)

  17. Appendicitis following blunt abdominal trauma.

    Science.gov (United States)

    Cobb, Travis

    2017-09-01

    Appendicitis is a frequently encountered surgical problem in the Emergency Department (ED). Appendicitis typically results from obstruction of the appendiceal lumen, although trauma has been reported as an infrequent cause of acute appendicitis. Intestinal injury and hollow viscus injury following blunt abdominal trauma are well reported in the literature but traumatic appendicitis is much less common. The pathophysiology is uncertain but likely results from several mechanisms, either in isolation or combination. These include direct compression/crush injury, shearing injury, or from indirect obstruction of the appendiceal lumen by an ileocecal hematoma or traumatic impaction of stool into the appendix. Presentation typically mirrors that of non-traumatic appendicitis with nausea, anorexia, fever, and right lower quadrant abdominal tenderness and/or peritonitis. Evaluation for traumatic appendicitis requires a careful history and physical exam. Imaging with ultrasound or computed tomography is recommended if the history and physical do not reveal an acute surgical indication. Treatment includes intravenous antibiotics and surgical consultation for appendectomy. This case highlights a patient who developed acute appendicitis following blunt trauma to the abdomen sustained during a motor vehicle accident. Appendicitis must be considered as part of the differential diagnosis in any patient who presents to the ED with abdominal pain, including those whose pain begins after sustaining blunt trauma to the abdomen. Because appendicitis following trauma is uncommon, timely diagnosis requires a high index of suspicion. Copyright © 2017 Elsevier Inc. All rights reserved.

    Radiological findings of abdominal tuberculosis can mimic those of many different diseases. A high level of suspicion is required, especially in high-risk population. In this article, we will describe barium studies, ultrasound (US) and computed tomography (CT) findings of abdominal tuberculosis (TB), with emphasis in the latest. We will illustrate CT findings that can help in the diagnosis of abdominal tuberculosis and describe imaging features that differentiate it from other inflammatory and neoplastic diseases, particularly lymphoma and Crohn's disease. As tuberculosis can affect any organ in the abdomen, emphasis is placed to ileocecal involvement, lymphadenopathy, peritonitis and solid organ disease (liver, spleen and pancreas). A positive culture or hystologic analysis of biopsy is still required in many patients for definitive diagnosis. Learning objectives:1.To review the relevant pathophysiology of abdominal tuberculosis. 2.Illustrate CT findings that can help in the diagnosis

    Full Text Available Desmoid tumors (also called desmoids fibromatosis are rare slow growing benign and musculoaponeurotic tumors. Although these tumors have a propensity to invade surrounding tissues, they are not malignant. These tumors are associated with women of fertile age, especially during and after pregnancy. We report a young female patient with a giant desmoid tumor of the anterior abdominal wall who underwent primary resection. The patient had no history of an earlier abdominal surgery. Preoperative evaluation included abdominal ultrasound, computed tomography, and magnetic resonance imaging. The histology revealed a desmoid tumor. Primary surgical resection with immediate reconstruction of abdominal defect is the best management of this rarity. To the best of our knowledge and PubMed search, this is the first case ever reported in the medical literature of such a giant desmoid tumor arising from anterior abdominal wall weighing 6.5 kg treated surgically with successful outcome.

    Full Text Available Metabolic Syndrome (MetS is highly prevalent and has considerable public health impact, but its underlying genetic factors remain elusive. To identify gene networks involved in MetS, we conducted whole-genome expression and genotype profiling on abdominal (ABD and gluteal (GLU adipose tissue, and whole blood (WB, from 29 MetS cases and 44 controls. Co-expression network analysis for each tissue independently identified nine, six, and zero MetS-associated modules of coexpressed genes in ABD, GLU, and WB, respectively. Of 8,992 probesets expressed in ABD or GLU, 685 (7.6% were expressed in ABD and 51 (0.6% in GLU only. Differential eigengene network analysis of 8,256 shared probesets detected 22 shared modules with high preservation across adipose depots (D(ABD-GLU = 0.89, seven of which were associated with MetS (FDR P100,000 individuals; rs10282458, affecting expression of RARRES2 (encoding chemerin, was associated with body mass index (BMI (P = 6.0×10(-4; and rs2395185, affecting inter-depot differences of HLA-DRB1 expression, was associated with high-density lipoprotein (P = 8.7×10(-4 and BMI-adjusted waist-to-hip ratio (P = 2.4×10(-4. Since many genes and their interactions influence complex traits such as MetS, integrated analysis of genotypes and coexpression networks across multiple tissues relevant to clinical traits is an efficient strategy to identify novel associations.

  6. Abdominal pain in physical therapy practice: 3 patient cases.

    2013-02-01

    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

    Ultrasound (US) imaging can be used for the measurement of trunk muscle activity. The displacements of US transducer, especially during more dynamic situations, however, may disturb the measurement results. To control this variable, some studies have used transducer fixator (TF), but no study evaluated the effect of using TF on US reliability in dynamic situations. The present study discriminated this issue. To investigate the intrasession and intersession reliability of lateral abdominal muscle thickness measurement in dynamic standing postural tasks by using US with and without TF in participants with and without chronic low back pain (CLBP). An intersession and intrasession reliability study. Biomechanics laboratory, Neuromuscular Rehabilitation Research Center, Semnan University of Medical Sciences, Semnan, Iran. Twenty-three patients with CLBP and 23 healthy matched individuals. Abdominal muscle thickness of all the subjects was evaluated with use of US imaging with the patient in the supine position and double-leg stance at different levels of platform stability of BBS (static, levels 6 and 3), with and without using TF. Intraclass correlation coefficients (ICCs), standard errors of measurement, minimal metrically detectable changes, and coefficients of variation were calculated to determine intersession and intrasession reliability of muscle activity measure. Lateral abdominal muscle thickness. The intersession ICCs in the conditions with TF ranged from 0.93 to 0.98 and 0.97 to 0.99 in CLBP and healthy individuals, respectively. The intersession ICCs in the conditions without TF ranged from 0.67 to 0.79 and 0.7 to 0.86 in CLBP and healthy groups, respectively. In addition, smaller standard errors of measurement and minimal metrically detectable change values were observed with US measurement in both the groups when TF was used. US imaging appears to have acceptable reliability for the assessment of abdominal muscle thickness during dynamic standing tasks in

    To describe the presence of heterotopic gastric mucosa forming an abscess associated with acute abdominal pain and shock in a puppy. A 7-month-old male intact Shih-Tzu was presented to the emergency service for evaluation of a 12-hour history of vomiting and lethargy progressing to weakness. On presentation, the puppy was obtunded and hypotensive. Radiographs revealed an ill-defined mid-ventral abdominal mass. Ultrasound revealed an echogenic, fluid-filled mass associated with the jejunum. The puppy had an exploratory celiotomy and a 2 × 4 cm oval fluid-filled soft tissue mass was found to be intimately associated, but not communicating with, a section of the mid-jejunum. The mass and associated jejunum were removed via enterectomy. Histopathology of the resected mass revealed heterotopic gastric mucosa; bacterial culture of the fluid contained in the mass revealed heavy growth of Escherichia coli. The puppy recovered from surgery, was discharged from the hospital, and has had no further complications from this episode. Heterotopic gastric mucosa is commonly found incidentally on necropsy. When it has been associated with acute gastrointestinal signs, mechanical intestinal obstruction with or without perforation was noted. To the authors' knowledge, this is the first reported case of heterotopic gastric mucosa leading to abscess formation and acute abdominal pain in the dog. © Veterinary Emergency and Critical Care Society 2014.

    1998-04-01

    Surgeon-interpreted diagnostic ultrasound has become the preferred screening test and often the definitive test for the diagnosis of arterial stenosis, aneurysm, and venous thrombosis. As a modality for surveillance, its noninvasive quality makes it particularly appealing as the test of choice to screen patients for abdominal aortic aneurysms or to perform follow-up examinations on those patients with a carotid endartectomy or in situ bypass grafts. The increasing reliance on intraoperative duplex imaging of vascular procedures demands that the surgeon learn the skills to perform the studies without a technologist or radiologist to interpret the examination.

  15. Aggressive malignant abdominal mesothelioma: Clinical report

    International Nuclear Information System (INIS)

    2004-01-01

    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

    : Retrospective analysis of patients operated for abdominal wall endometrioma with emphasis on data relating to age, symptoms, previous cesarean, relation of symptoms with the menstrual cycle, physical examinations and additional surgical treatment, postoperative course and histopathological results of specimens. RESULTS: Forteen patients were operated during the study period, aged between 28 and 40 years. The presence of local mass and pain that worsened during menstruation were the main complaints. Ultrasound and CT examinations were important to precisely localize the disease. Surgical excision was a wide excision of the tumor and affected tissues. The patient progressed satisfactorily and histopathology confirmed the diagnosis of abdominal wall endometrioma in all cases. CONCLUSION: Exists a clear relationship between cesarean operation and abdominal wall endometrioma; ultrasound studies and CT scans help to plan the surgical resection allowing resection of tumor and all affected adjacent tissues.

  17. Adult abdominal hernias.

    LENUS (Irish Health Repository)

    Murphy, Kevin P

    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.

    2015-01-19

    Acute abdominal pain is a common clinical condition. Clinical signs and symptoms can be difficult to interpret, and diagnostic imaging may help to identify intra-abdominal disease. Conventional X-ray, ultrasound (US) and computed tomography (CT) of the abdomen vary in usability between common surgical causes of acute abdominal pain. Overall, conventional X-ray cannot confidently diagnose or rule out disease. US and CT are equally trustworthy for most diseases. US with subsequent CT may enhance diagnostic precision. Magnetic resonance seems promising for future use in acute abdominal imaging.

    The purpose of this study was to investigate the changes in the thickness of the transversus abdominis (TrA) and internal oblique (IO) muscles in three sitting postures with different levels of stability. The technique of ultrasound imaging was used for individuals with and without chronic low back pain (LBP). A sample of 40 people participated in this study. Subjects were categorised into two groups: with LBP (N = 20) and without LBP (N = 20). Changes in the thickness of tested muscles were normalized under three different sitting postures to actual muscle thickness at rest in the supine lying position and were expressed as a percentage of thickness change. The percentage of thickness change in TrA and IO increased as the stability of the sitting position decreased in both groups. However, the percentages of thickness change in all positions were less in subjects with LBP. There was a significant difference in thickness change in TrA when sitting on a gym ball between subjects with and without LBP but no difference was found when sitting on a chair. There was no significant difference in thickness change in IO in all positions between the two groups. Our findings indicate that difference in the percentage of thickness change in TrA between subjects with and without LBP increases as the stability of sitting position decreases.

    Nathan M. Droz, MD

    2017-03-01

    Full Text Available Abdominal aortic aneurysm (AAA is a significant source of morbidity and ranked by the Centers for Disease Control and Prevention as the 15th leading cause of death among adults aged 60 to 64 years. Size confers the largest risk factor for aneurysm rupture, with aneurysms >6 cm having an annual rupture risk of 14.1%. We present the case of a 60-year-old man found on ultrasound imaging at a health fair screening to have a 15-cm AAA. Follow-up computed tomography angiography revealed an 18-cm × 10-cm unruptured, infrarenal, fusiform AAA. Giant AAAs, defined as >11 cm, are rarely described in the literature. Our patient underwent successful transperitoneal AAA repair with inferior mesenteric artery reimplantation and was discharged home on operative day 6. We believe this case represents one of the largest unruptured AAAs in the literature and demonstrates the feasible approach for successful repair.

    2012-01-01

    Purpose: Trans-abdominal ultrasonography (US) is capable of determining size, shape, thickness, and diameter of uterus, cervix and disease at cervix or parametria. To assess the potential value of US for image-guided cervical cancer brachytherapy, we compared US-findings relevant for brachytherapy to the corresponding findings obtained from MR imaging. Materials and methods: Twenty patients with biopsy proven cervical cancer undergoing definitive radiotherapy with/without concomitant Cisplatin chemotherapy and suitable for brachytherapy were invited to participate in this study. US and MR were performed in a similar reproducible patient positioning after intracavitary application. US mid-sagittal and axial image at the level of external cervical os was acquired. Reference points D1 to D9 and distances were identified with respect to central tandem and flange, to delineate cervix, central disease, and external surface of the uterus. Results: Thirty-two applications using CT/MR compatible applicators were evaluable. The D1 and D3 reference distances which represent anterior surface had a strong correlation with R = 0.92 and 0.94 (p < 0.01). The D2 and D4 reference distances in contrast, which represent the posterior surface had a moderate (D2) and a strong (D4) correlation with R = 0.63 and 0.82 (p < 0.01). Of all, D2 reference distance showed the least correlation of MR and US. The D5 reference distance representing the fundal thickness from tandem tip had a correlation of 0.98. The reference distances for D6, D7, D8, and D9 had a correlation of 0.94, 0.82, 0.96, and 0.93, respectively. Conclusions: Our study evaluating the use of US, suggests a reasonably strong correlation with MR in delineating uterus, cervix, and central disease for 3D conformal intracavitary brachytherapy planning.

    The purpose of this study was to describe ultrasound (US) changes in muscle thickness produced during automatic activation of the transversus abdominis (TrAb), internal oblique (IO), external oblique (EO), and rectus abdominis (RA), as well as the cross-sectional area (CSA) of the lumbar multifidus (LM), after 1 year of Pilates practice. A 1-year follow-up case series study with a convenience sample of 17 participants was performed. Indeed, TrAb, IO, EO, and RA thickness, as well as LM CSA changes during automatic tests were measured by US scanning before and after 1 year of Pilates practice twice per week. Furthermore, quality of life changes using the 36-Item Short Form Health Survey and US measurement comparisons of participants who practiced exercises other than Pilates were described. Statistically significant changes were observed for the RA muscle thickness reduction during the active straight leg raise test (P = .007). Participants who practiced other exercises presented a larger LM CSA and IO thickness, which was statistically significant (P .05). A direct moderate correlation was observed (r = 0.562, P = .019) between the TrAb thickness before and after a 1-year follow-up. Long-term Pilates practice may reduce the RA thickness automatic activation during active straight leg raise. Furthermore, LM CSA and IO thickness increases were observed in participants who practice other exercise types in conjunction with Pilates. Despite a moderate positive correlation observed for TrAb thickness, the quality of life did not seem to be modified after long-term Pilates practice. Copyright © 2018. Published by Elsevier Inc.

    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.

    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.

    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

    Ultrasound is a powerful, low-cost, non-invasive medical tool used by laboratory animal veterinarians for diagnostic imaging. Sonohysterography and transvaginal ultrasound are frequently used to assess uterine anomalies in women presenting with abnormal uterine bleeding (AUB). In the present study, we have evaluated the abdominal ultrasound of bonnet monkeys ( n = 8) showing spontaneous ovulatory ( n = 5) and anovulatory ( n = 3) AUB. The ovulatory ( n = 5) macaques showed cyclic AUB for 7-8 days. The anovulatory ( n = 3) macaques had irregular AUB with menstrual cycles of 40-45 days. The B-mode abdominal, colour Doppler and 3D ultrasound scans were performed during the proliferative phase of the menstrual cycle. Ultrasound examination revealed endometrial polyps in five macaques and endometrial hyperplasia in three animals. The width and length of endometrial polyps was around 0.5-1 cm (average 0.51 ± 0.23 cm × 0.96 ± 0.16 cm) with significant increase in endometrial thickness ( P uterine cavity and colour Doppler ultrasound showed increased vascularity in the endometrial polyps. Endometrial hyperplasia characteristically appeared as a thickened echogenic endometrium ( P < 0.0002). This study demonstrates the use of non-invasive ultrasound techniques in the diagnosis of AUB in macaques.

    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: 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

    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

  15. Non-traumatic abdominal emergencies: imaging and intervention in sepsis

    International Nuclear Information System (INIS)

    Lee, M.J.

    2002-01-01

    Cross-sectional imaging, in particular CT, has become the main method of detecting abdominal collections. Indium-labelled white-cell scintigraphy and gallium scintigraphy are reserved for patients in whom there is a high clinical suspicion of abdominal sepsis but CT has not revealed a source of sepsis. Scintigraphy is also used in patients with suspected vascular graft infections or suspected infected hip prostheses. Percutaneous abscess drainage (PAD) has revolutionised the treatment of abdominal abscesses over the past 20 years, with repeat laparotomy for postoperative abscesses becoming a rare event. Ultrasound or CT can be used to guide PAD. Choosing an access route that does not cross intervening organs is of crucial importance to the safe performance of PAD. The Trocar or Seldinger techniques can be used with equal success. The cavity should be aspirated until dry and irrigated with saline. Repeat imaging after drainage is helpful to detect any undrained locules. PAD endpoints include patient defervescence, reduction in white blood cell count and catheter drainage of less than 10 ml per day. Details regarding PAD in specific abdominal regions are discussed. Success rates for PAD are high (close to 90%) in most abdominal organs. Slightly lower success rates are seen with PAD of pancreatic abscesses and abscesses associated with fistulas (60-85% success rates). Complication rates lie between 0% and 10%. Complications can be minimised by ensuring that the patient has broad spectrum antibiotic coverage before drainage, by carefully planning the access route and by ensuring diligent post-procedure care by radiology staff.

    Grover, Hemal; Sethi, Sanjay; Garg, Jatin; Ahluwalia, Amrit Pal

    2017-01-01

    Summary Background Prune Belly Syndrome (PBS) is a rare entity, usually found in male neonates. It comprises complex urinary tract anomalies, bilateral undescended testis and absence of anterior abdominal wall muscles. Patients with unilateral abdominal wall deficiency, unilateral undescended testis and female neonates with abdominal wall laxity are classified as Pseudo Prune Belly syndrome (PPBS). Reports on PPBS do not highlight the radiological and imaging characteristics of this syndrome and the current literature on the role of newer imaging modalities, such as Magnetic Resonance Imaging (MRI), remains relatively sparse. We describe a new case of PPBS and emphasize the role of imaging, especially ultrasound and MRI in the process of diagnosis and briefly review the subject. Case Report A male infant of four months of age was referred for evaluation of left-sided cryptorchidism. Clinical examination revealed laxity of the left abdominal wall. Ultrasound examination of the abdomen, pelvis and scrotum was performed together with routine laboratory tests. Ultrasound examination was followed by intravenous urography, voiding cysto-urethrography and MRI of the abdomen. On ultrasound, the left testis was located in the inguinal canal, the right kidney was slightly enlarged and the left kidney could not be localized. Ultrasound appearances suggested chronic obstruction in the urinary bladder. Intravenous urography, voiding cysto-urethrography and MRI confirmed the ultrasound diagnosis and also revealed a left dysplastic kidney with a dilated, tortuous ureter. Clinical and imaging features were consistent with pseudo prune belly syndrome (PPBS). Conclusions We report a new occurrence of PPBS, a rare entity. The imaging approach for a comprehensive evaluation of the renal system in PPBS, especially with MRI, is emphasized. PMID:28580040

    2015-01-01

    Herpes zoster (HZ) most commonly occurs in elderly patients and involves sensory neurons resulting in pain and sensory changes. Clinically significant motor deficits and visceral neuropathies are thought to be relatively rare. A 72-year-old man presented with abdominal segmental hernia, constipation, and pain following HZ in the left T9-10 dermatome. Sixteen days before presentation, he had developed a painful herpetic rash in the left upper abdominal quadrant. Approximately 10 days after the onset of the rash, constipation occurred and was managed with daily oral medication with bisacodyl 5 mg. In addition, 14 days after the onset of HZ, the patient noticed a protrusion of the left upper abdominal wall. Abdominal x-ray, ultrasound of the abdomen, and electrolyte analysis showed no abnormalities. General physical examination revealed a reducible bulge in his left upper quadrant and superficial abdominal reflexes were diminished in the affected region. Electromyographic testing revealed denervational changes limited to the left thoracic paraspinal muscles and supraumbilical muscles, corresponding to the affected dermatomes. He was prescribed with 500 mg of famciclovir 3 times a day for 7 days, and pregabalin 75 mg twice a day and acetaminophen 650 mg 3 times a day for 14 days. However, his pain was rated at an intensity of 5 on the numerical analogue scale from 0 (no pain) to 10 (worst pain imaginable). A paravertebral block was performed at T9-10 with a mixture of 0.5% lidocaine 3 mL and triamcinolone 40 mg. One day after the procedure, the abdominal pain disappeared. In addition, 5 days after the intervention, the abdominal protrusion and constipation were resolved. He currently remains symptom free at a 6 month follow-up.

  20. Torsion of abdominal appendages presenting with acute abdominal pain

    International Nuclear Information System (INIS)

    Al-Jaberi, Tareq M.; Gharabeih, Kamal I.; Yaghan, Rami J.

    2000-01-01

    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)

    Background. Acute intestinal obstruction during pregnancy is a very challenging and unusual nonobstetric surgical entity often linked with considerable fetomaternal morbidity and mortality. When it is synchronous with abdominal pregnancy, it is even rarer. Case Presentation. A 28-year-old lady in her second pregnancy was referred to Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria, at 27 weeks of gestation due to vomiting, constipation, and abdominal pain. Examination and ultrasound scan revealed a single live intra-abdominal extrauterine fetus. Plain abdominal X-ray was diagnostic of intestinal obstruction. Conservative treatment was successful till the 34-week gestational age when she had exploratory laparotomy. At surgery, the amniotic sac was intact and the placenta was found to be adherent to the gut. There was also a live female baby with birth weight of 2.3 kg and Apgar scores of 9 and 10 in the 1st and 5th minutes, respectively, with the baby having right clubbed foot. Adhesiolysis and right adnexectomy were done. The mother and her baby were well and were discharged home nine days postoperatively. Conclusion. To the best of our knowledge, this is the first report of abdominal pregnancy as the cause of acute intestinal obstruction in the published literature. Management approach is multidisciplinary.

    Full Text Available Background: The aims of this study have been elaborated below: (1 to enumerate the common causes of acute abdominal emergencies by ultrasonography in paediatric patients; (2 to establish the diagnostic efficacy of ultrasonography in evaluation of acute abdominal conditions in children and to illustrate the associated ultrasonographic findings; (3 and, to discuss the role of ultrasonography in guiding the mode of intervention in these cases. 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.

    Lateral abdominal wall muscles in children and adolescents have not been characterised to date. In the present report, we examined the reliability of the ultrasound measurement and thickness of the oblique external muscle (OE), oblique internal muscle (OI) and transverse abdominal muscle (TrA) at rest and during abdominal drawing-in manoeuvre (ADIM) on both sides of the body in healthy adolescents. We also determined possible differences between boys and girls and defined any factors-such as body mass, height and BMI-that may affect the thickness of the abdominal muscles. B-mode ultrasound was used to assess OE, OI and TrA on both sides of the body in the supine position. Ultrasound measurements at rest and during ADIM were reliable in this age group (ICC3,3 > 0.92). OI was always the thickest and TrA the thinnest muscle on both sides of the body. In this group, an identical pattern of the contribution of the individual muscles to the structure of the lateral abdominal wall (OI > OE > TrA) was observed. At rest and during ADIM, no statistically significant side-to-side differences were demonstrated in either gender. The body mass constitutes between 30% and <50% of the thickness differences in all muscles under examination at rest and during ADIM. The structure of lateral abdominal wall in adolescents is similar to that of adults. During ADIM, the abdominal muscles in adolescents react similarly to those in adults. This study provided extensive information regarding the structure of the lateral abdominal wall in healthy adolescents. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Abdominal cystic formations in newborns are relatively common and often diagnostic suspicion arises before birth as a result of ultrasound scans carried out during pregnancy. Prenatal ovarian torsion is a rare condition very difficult to manage in the first days of life. We report and discuss the management of prenatal ovarian torsion with a free-floating abdominal cyst detected on prenatal ultrasound. We recorded the cases of antenatal abdominal cysts detected on ultrasound at the Department of Antenatal Diagnosis between January 2003 and January 2007. Only patients with a free-floating cyst were included in the study. Clinical and surgical findings were then recorded. Two out of 57 patients underwent surgery for a free-floating abdominal cyst during the second day of life. Postnatal ultrasound, Doppler ultrasound, and laparoscopic exploration were useful to identify an unusual presentation of antenatal ovarian torsion with a complete atresia of the Fallopian tube. The cases reported in this study suggest that a good clinical approach to all cases of abdominal cysts detected on prenatal ultrasound scans require postnatal Doppler and abdominal ultrasound with a laparoscopic exploration. Free-floating abdominal cysts are rare but, at the same time, strictly correlated with autoamputation of the ovary/Fallopian tube complex.

    The quadratus lumborum blockade was described by R. Blanco in its two approaches (I and II). The local anesthetic deposition in this location can provide blockade to T6-L1 dermatomes. We performed this fascia blockade guided by ultrasound for treating a chronic neuropathic pain in the abdominal wall. Male patient, 61 years old, 83kg, with a history of thrombocytopenia due to alcoholic cirrhosis, among others; had chronic pain in the abdominal wall after multiple abdominal hernia repairs in the last year and a half, with poor response to treatment with neuromodulators and opioids. On clinical examination, he revealed a neuropathic pain, with prevalence of allodynia to touch, covering the entire anterior abdominal wall, from T7 to T12 dermatomes. We opted for a quadratus lumborum block type II, guided by ultrasound, with administration of 0.2% ropivacaine (25mL) and depot (vial) methylprednisolone (20mg) on each side. The procedure gave immediate relief of symptoms and, after six months, the patient still had a significant reduction in allodynia without compromising the quality of life. We consider that performing the quadratus lumborum block type II was an important analgesic option in the treatment of a patient with chronic pain after abdominal hernia repair, emphasizing the effects of local anesthetic spread to the thoracic paravertebral space. The technique has proven to be safe and well tolerated. The publication of more clinical cases reporting the effectiveness of this blockade for chronic pain is desirable.

    2017-08-01

    Full Text Available Undifferentiated carcinoma with osteoclast-like cells is a rare pancreatic neoplasm with unique ultrasound endoscopic features. A 59-year-old female presented with a 3-month history of weight loss. Abdominal computed tomography and endoscopic ultrasound showed a large pancreatic tumor with a heterogeneous echotexture and liver metastasis. Endoscopic ultrasound fine needle aspiration was used to establish the diagnosis. In this case report, we review the endoscopic, clinical, and pathological features of this type of tumor and describe for the first time the endoscopic features of real-time elastography and contrast enhancement. Real-time elastography revealed a heterogeneous predominantly blue pattern suggestive of pancreatic malignancy, and the contrast-enhanced endosonography showed a hypervascular mass and distinctive vascular (solid and avascular (liquid/necrotic components of the lesion, guiding the fine needle aspiration.

    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.

    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

  13. Desmoid Tumor of the Anterior Abdominal Wall in Female Patients: Comparison with Endometriosis

    Directory of Open Access Journals (Sweden)

    H. Krentel

    2012-01-01

    Full Text Available In female patients presenting a tumor of the lower abdominal wall especially after cesarian section, an endometriotic tumor as well as an aggressive desmoid tumor should be considered. Symptoms in correlation with the monthly period can facilitate the presurgical differentiation between endometriosis and fibromatosis. Ultrasound reveals the typical location of both tumors and its remarkable sonographic appearance. In the clinical practice, the desmoid fibromatosis of the lower abdominal wall is a very rare disease. We present a case of a 25-year-old pregnant and discuss diagnostic and therapeutic options by a PubMed literature review. With the knowledge of the prognosis of the desmoid fibromatosis and the respective treatment options including wait and see, complete surgical resection with macroscopically free margins and adjuvant approaches is essential to avoid further interventions and progression of the locally destructive tumor.

    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

  15. Uncommon external abdominal oblique muscle strain in a professional soccer player: a case report.

    Dauty, Marc; Menu, Pierre; Dubois, Charles

    2014-10-01

    This is the first report of external abdominal oblique muscle injury occurring in a professional soccer player. A 28-year-old Caucasian professional soccer player presented after experiencing a popping sensation associated with strong parietal pain localized between the left 11th and 12th ribs. Ultrasound examination revealed a collection of fluid under the 11th rib, suggesting injury of the left external oblique muscle. Platelet-rich plasma treatment was administered and the soccer player returned to competition on the 21st day after treatment. This rare injury results from a sudden intrinsic eccentric contraction of the internal oblique muscle while in a stretched position. Ultrasound can help to confirm the diagnosis and to monitor clinical follow-up. Platelet-rich plasma treatment could aid recovery in high-level athletes.

  16. Abdominal Trauma: Never Underestimate It

    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.

    Mortimer, Alice Emily

    2014-11-14

    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.

    1997-01-01

    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....

    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

MÉTODOS: A população estudada foi constituída por 145 pacientes com obesidade grau III (IMC > 40 Kg/m², de ambos os sexos. O diagnóstico da DHGNA foi realizado por ultrassonografia e ressonância magnética. Em uma subamostra foi realizado o diagnóstico por biópsia hepática (n=40. Para avaliar a concordância entre os diagnósticos por USG e RM, utilizou-se o coeficiente Kappa. RESULTADOS: Observou-se uma concordância fraca entre os dois métodos (Kappa ajustado= 0,27; IC 95%= 0,07-0,39. Foi encontrada uma concordância moderada entre o diagnóstico da doença por USG e biópsia hepática, com 83,3% de resultados concordantes e Kappa ajustado de 0,67.

This paper describes the development of an ultrasound based imaging system capable of generating 3D images showing surface and subsurface tissue and bone structures. We include results of a comparative study between images obtained from X-Ray Computed Tomography (CT) and ultrasound. We found that the quality of ultrasound images compares favorably with those from CT. Volumetric and surface data extracted from these images were within 7% of the range between ultrasound and CT scans. We also include images of porcine abdominal scans from two different sets of animal trials.

    OBJECTIVE: To determine if Fetal Abdominal Subcutaneous Tissue (FAST) measurements using antenatal ultrasound differ between male and female fetuses. STUDY DESIGN: Women who had an ultrasound examination for fetal growth between 20 and 40 weeks gestation were studied. Women with diabetes mellitus were excluded. The fetal anterior abdominal subcutaneous tissue was measured on the anterior abdominal wall in millimetres anterior to the margins of the ribs, using magnification at the level of the abdominal circumference. The fetal sex was recorded after delivery. RESULTS: A total of 557 fetuses were measured, 290 male and 267 female. The FAST measurements increased with gestational age. The FAST increased at the same rate for both male and female fetuses and at any given week there was no sex difference. CONCLUSIONS: The increased fat composition in females reported after birth was not found in abdominal wall subcutaneous fat measurements using ultrasound during pregnancy. Antenatal centile charts for FAST do not need to be based on sex.

    Transversus abdominal plane (TAP) block is a known and useful technique, widely used for postoperative pain management of abdominal wall incisions. During the past years, and following the expansion of ultrasound guided techniques, its use has even gained more adepts. It is usually used as an adjuvant technique, primarily in order to control postoperative pain and reduce opioids consumption. We report the case of an 82 years old patient admitted for drainage of a postoperative abdominal wall hematoma after correction of a McBurney incisional hernia. The corrective surgery had gone on without incident, under general anesthesia with laryngeal mask. Two weeks later, the patient came back to our emergency department with a clear hematoma of the abdominal wall. Surgery was decided. A sole local anesthetic technique was achieved, using a TAP block. The block was performed under ultrasound guidance, using a subcostal approach. The surgery went on without complications. Therefore, TAP block offers a hemodynamic stability, appropriate intra-operative anesthesia and post-surgical analgesia of the abdominal wall.

    Full Text Available No abstract available. Article truncated at 150 words. An 88 year-old presented to the emergency department with left flank and lower back pain as well as lower abdominal fullness. The fullness had started 2 days prior, but the left flank pain acutely started in the early morning before presenting. He had a history of unmedicated hypertension, hyperlipidemia, and mild vertigo. His review of systems was positive for chills and difficulty urinating but no hematuria. He was a non-smoker, and had undergone orthopedic surgeries but had otherwise avoided emergent hospitalizations. On exam, vitals were unremarkable; there was no flank nor costovertebral angle tenderness; however, a midline pulsatile mass was present. An initial non-contrast CT abdomen/pelvis revealed a massive abdominal aortic aneurysm (AAA, Figure 1. Follow-up CT angiogram of the AAA can be seen in Figure 2.

    Full Text Available : Introduction: Primary vascular tumors are rare and, in general, have a poor prognosis. Complete resection is associated with a better prognosis. Radical resection depends on safe discrimination of tumor borders. Technical summary: A 54 year old woman presented with abdominal pain. Imaging revealed a mass in the thoracic aorta, highly suspicious of angiosarcoma which was confirmed post-operatively by histological analysis. Open surgery was performed. Prior to clamping of the aorta, intra-operative ultrasound established clear delineation of the tumor borders. Conclusion: Intra-operative ultrasound was, in this case, a safe and easy method to determine the tumor borders, providing a simple guide to in toto tumor removal.

    Using ultrasound imaging, the abdominal muscles' response to the back extensor muscle fatigue was assessed in subjects with chronic low-back pain (CLBP). Lumbar muscle fatigue is a common occurrence among workers. Alteration in motor coordination is one consequence of muscular fatigue. According to previous studies, CLBP subjects use their back and abdominal muscles in different ways, but questions remain about abdominal muscle responses to back muscle fatigue in CLBP patients. Thirteen CLBP patients and 15 healthy subjects participated in this study. The thickness of abdominal muscles-including transverse abdominis (TrA), internal oblique abdominis (IO), and external oblique abdominis (EO) muscles-was measured in standing position with and without axial loads before and after a lifting fatigue task. The results reveal a significant difference for the main effects of group on percentage of change in TrA thickness (F = 8.9, p = .004). Percentage of change in thickness of TrA was 10% greater in the CLBP group. Although IO thickness displayed greater percentage of change in the CLBP group, the difference between groups was not significant. Abdominal muscle behavior changes with back-muscle fatigue in both healthy and CLBP subjects, but responses were more exaggerated in CLBP patients. Ultrasound imaging technique can provide critical information about the effect of fatigue on spinal muscle activation and consequently about the stability of the spine. As a more applicable and easy technique, ergonomists can use ultrasound imaging in musculoskeletal system assessment in worker populations in future studies. © 2014, Human Factors and Ergonomics Society.

    Validation study. To investigate the association between changes in electromyographic (EMG) signal amplitude and sonographic measures of muscle thickness of 4 abdominal muscles, during 2 clinical tests, in adults with and without lumbopelvic pain. There is a trend in rehabilitation to use ultrasound imaging (USI) to determine the extent of abdominal muscle contraction. However, the literature investigating the relationship between abdominal muscle thickness change and level of activation is inconclusive and has not included clinically relevant tasks. Simultaneous recording from fine-wire EMG and USI was performed for 4 abdominal muscles, in 7 adults with lumbopelvic pain (mean ± SD age, 29.7 ± 12.0 years) and 7 adults without lumbopelvic pain (32.0 ± 10.6 years), during an active straight leg raise (ASLR) test and an abdominal drawing-in maneuver (ADIM). Cross-correlation functions and linear regression analyses were used to describe the relationship between the 2 measures. Analyses of variance were used to compare individuals with and without lumbopelvic pain, with an alpha set at .05. Across all muscles, peak cross-correlation values were low (ASLR, r = 0.28 ± 0.09; ADIM, r = 0.35 ± 0.11), and there was large variability in associated time lags (ASLR, τ = 0.69 ± 2.56 seconds; ADIM, τ = 0.53 ± 3.75 seconds). Regression analyses did not detect a systematic pattern of association between EMG signal amplitude and USI measurements, and analyses of variance revealed no differences between cohorts. These results suggest a weak relationship between EMG amplitude and abdominal muscle thickness change measured with USI during the ADIM and ASLR, and raise questions about thickness change derived from USI as a measure of muscular activity for the abdominal musculature.

    Neurilemmoma, also known as schwannoma, is an uncommon benign neoplasm that is most commonly found in the trunk and head and neck regions. The present study reports the case of a 67-year-old female with schwannoma localized in the anterior abdominal wall and analyzes the ultrasound and computed tomography (CT) imaging observations of the schwannoma. A dynamic time-intensity curve was also recorded in the study. A well-defined, elliptic low echo level, heterogeneous mass was observed during ultrasound examination. The CT scan revealed a solid, heterogeneous, low-density mass in the abdominal wall. Contrast-enhanced scans showed a heterogeneously enhanced mass during the arterial and venous phase. Centripetal fill-in was demonstrated and the mass was markedly, homogenously enhanced relative to the muscles during the delayed phase. Peak enhancement was observed during the venous phase and then slowly declined. However, the mass was hyperattenuated during the delayed phase. The lesion was completely excised and no evidence of recurrence has been identified during the 3 months of follow-up. The present study suggested that a diagnosis of schwannoma should be considered for certain patients with masses in the abdominal wall. Peripheral enhancement during the arterial and venous phases and homogeneous enhancement in the delayed phase are the significant imaging findings of a schwannoma.

    Using simple and standardized semiology, the lung appears accessible to ultrasound, despite previous opinions otherwise. Lung ultrasound allows the intensivist to quickly answer to a majority of critical situations. Not only pleural effusion but also pneumothorax, alveolar consolidation, and interstitial syndrome will have accurate ultrasound equivalents, the recognition of which practically guides management. Combined with venous, cardiac, and abdominal examination, ultrasound investigation of this vital organ provides a transparent overview of the critically ill, a kind of stethoscope for a visual medicine. It is believed that by using this tool, the intensivist may more confidently manage acute dyspnea and make emergency therapeutic decisions based on reproducible data. Further benefits include reduced requirements for computed tomographic scans, therefore decreasing delay, irradiation, cost, and above all, discomfort to the patient. Thus, ultrasound of the lung can also be added to the classic armamentarium as a clinical tool for emergency use.

    The clinical presentation of adrenal hemorrhage varies, depending on the extent of hemorrhage as well as the amount of adrenal cortex involved by the hemorrhage. We report here a case of neonatal adrenal hemorrhage revealed by late onset of neonatal jaundice. This adrenal hemorrhage most probably resulted from shoulder dystocia. The aim of this work was to focus on the fact that jaundice can be caused by adrenal hemorrhage and to emphasize the crucial importance of abdominal ultrasound in cases of persistent jaundice.

    Diagnostic ultrasound was used as early as 1950 in attempts to detect malignant tumors within the human breast and brain. In the years following, however, little attention was paid to this method of imaging by the radiologic community. Extensive work with this technique was not begun until the 1960s, when bistable ultrasound enabled sonographers to display organ outlines for the first time. Prior to the development of bistable ultrasound, sonographic images were limited to A-mode displays, which were merely a series of amplitude spikes on a graph. Over the past 20 or so years, major advances in ultrasound technology have gradually taken us from the simple graphic A-mode display, through bistable organ outlines, to gray-scale images with excellent parenchymal detail, and finally to real-time ultrasound

    Full Text Available Background: acute appendicitis (AA is the acute surgical abdominal disease more common in the Hospital Susana López de Valencia Popayán, Colombia; its diagnosis is one of the most common problems in emergency. Objective: to determined the operating performance of emergency ultrasound in suspected acute appendicitis. Methods: retrospective study conducted with data obtained from the first of January to 31 December 2011, including patients with presumed diagnosis of AA and abdominal ultrasound before surgery. Results: a total of 134 individuals who underwent surgery, with pre-procedure ultrasound report and pathology report. The performance of ultrasound resulted in a sensitivity of 73.2%, specificity 86.3%, positive predictive value of 96.4%, negative predictive value of 38.7%. Conclusion: the overall performance of abdominal ultrasound in the diagnosis of acute appendicitis in our hospital is acceptable. But its usefulness is poor in excluding the diagnosis of acute appendicitis. Because of its accessibility and low cost is the best test available for diagnosis in doubtful cases in emergency or difficult diagnosis.

    Controlled laboratory study. The hip abductor muscles are important hip joint stabilizers. Hip joint pain may alter muscle recruitment. Motion-mode (M-mode) ultrasound enables noninvasive measurements of the onset of deep and superficial muscle motion, which is associated with activation onset. To compare (1) the onset of superficial and deep gluteus medius and gluteus minimus muscle motion relative to the instant of peak ground reaction force and (2) the level of swing-phase muscle motion during step-down between subjects with chronic hip pain and controls using M-mode ultrasound. Thirty-five subjects with anterior, nontraumatic hip pain for more than 6 months (mean ± SD age, 54 ± 9 years) and 35 controls (age, 57 ± 7 years) were scanned on the lateral hip of the leading leg during frontal step-down onto a force platform using M-mode ultrasound. Computerized motion detection with the Teager-Kaiser energy operator was applied on the gluteus minimus and the deep and superficial gluteus medius to determine the time lag between muscle motion onset and instant of peak ground reaction force and the level of gluteus minimus motion during the swing phase. Time lags and motion levels were averaged per subject, and t tests were used to determine between-group differences. In participants with hip pain, gluteus minimus motion onset was 103 milliseconds earlier (P = .002) and superficial gluteus medius motion was 70 milliseconds earlier (P = .047) than those in healthy control participants. The level of gluteus minimus swing-phase motion was higher with pain (P = .006). Increased gluteus minimus motion during the swing phase and earlier gluteus minimus and superficial gluteus medius motion in individuals with hip pain suggest an overall increase of muscle activity, possibly a protective behavior.

    The occurrence of traumatic abdominal wall hernia secondary to blunt trauma is uncommon, and laparoscopic repair of such hernias is very rare. A 53-year-old man, who had sustained injuries to his right thigh and right abdomen 8 months previously, visited a hospital because of a bulge in the right lateral abdomen. An abdominal computed tomography scan revealed a rupture in the lateral abdominal muscle and herniation of the cecum into the subcutaneous space. Accordingly, delayed traumatic abdominal wall hernia was diagnosed, which was successfully repaired laparoscopically. Thus, a laparoscopic tension-free mesh repair was safely and effectively performed for delayed traumatic abdominal wall hernia.

    We present a case of an 18-year-old male who presented with complains of abdominal pain, nausea and vomiting for 2 years. An esophagogastroduodenoscopy (EGD) revealed a 3 mm nodule on the lesser curvature of the stomach and prominent gastric folds. Biopsy of the nodule revealed a well-differentiated neuroendocrine tumor (NET) in lamina prop with focal extension into muscularis mucosa consistent with a gastric carcinoid. Tumor cells stained with neuron-specific enolase (NSE), chromogranin and synaptophysin only. The prominent gastric fold biopsy revealed gastric fundic mucosa with mucosal edema and focal mild chronic inflammation. Serum gastrin level was found to be 2,083 pg/mL. Abdomen CT and endoscopic ultrasound (EUS) revealed a mass near the pancreatic neck. These findings were consistent with a functional gastrin producing well-differentiated grade 1 neuroendocrine neoplasm (gastrinoma). The patient underwent exploratory laparotomy with resection of the mass and resulting in normalization of gastrin levels.

    2018-05-01

    Abdominal aortic aneurysm (AAA) is most commonly defined as a maximal diameter of the abdominal aorta in excess of 3 cm in either anterior-posterior or transverse planes or, alternatively, as a focal dilation ≥ 1.5 times the diameter of the normal adjacent arterial segment. Risk factors for the development of AAA include age > 60, tobacco use, male gender, Caucasian race, and family history of AAA. Aneurysm growth and rupture risk appear to be associated with persistent tobacco use, female gender, and chronic pulmonary disease. The majority of AAAs are asymptomatic and detected incidentally on various imaging studies, including abdominal ultrasound, and computed tomographic angiography. Symptoms associated with AAA may include abdominal or back pain, thromboembolization, atheroembolization, aortic rupture, or development of an arteriovenous or aortoenteric fistula. The Screening Abdominal Aortic Aneurysms Efficiently (SAAAVE) Act provides coverage for a one-time screening abdominal ultrasound at age 65 for men who have smoked at least 100 cigarettes and women who have family history of AAA disease. Medical management is recommended for asymptomatic patients with AAAs  5 mm/6 months), or presence of a fusiform aneurysm with maximum diameter of 5.5 cm or greater. Intervention for AAA includes conventional open surgical repair and endovascular aortic stent graft repair.

    Ultrasound is a form of energy which consists of mechanical vibrations the frequencies of which are so high that they are above the range of human hearing. The lower frequency limit of the ultrasonic spectrum may generally be taken to be about 20 kHz. Most biomedical applications of ultrasound employ frequencies in the range 1-15 MHz. At these frequencies, the wavelength is in the range 1.5 - 0.1 mm in soft tissues, and narrow beams of ultrasound can be generated which propagate through such tissues without excessive attenuation. This chapter begins with brief reviews of the physics of diagnostic ultrasound pulse-echo imaging methods and Doppler imaging methods. The remainder of the chapter is a resume of the applications of ultrasonic imaging to physiological measurement
