Sonographycally guided hydrostatic reduction of childhood intussusception = Dezinvaginacija s hidrokolonsonografijo pri otroku by Dubravka Vidmar( )

1 edition published in 2004 in English and held by 3 WorldCat member libraries worldwide

Background. Intussusception is the most common cause of bowel obstruction in children under two years of age. The proximal part of the bowel and its mesentery (the intussusceptum) enter within that part immediately beneath it (the intussuscipiens). Being pulled by peristalsis the mesenterial vessels getcompressed which result in ishaemia of the bowel wall. Most intussusceptions are ileocolic. The diagnosis can be confirmed by a contrast enema or ultrasound. Sonography demonstrates a so-called target-within-a-target patfern (in cross-section) with thickened edematous bowel wall with or without vascularisation and prestenotic dilatation with increased peristalsis. Therapeutic reduction can be attempted by a contrast enema (following diagnostic procedure) or by air, both under fluoroscopic monitoring, or by normal saline under sonographic guidance. Patients and methods. We detected sonographically intussusception in three girls of 15, 16 and 18 months having typical clinical signs. We continued with hydrostatic reduction under the sonographic guidance. The reduction was attempted with a saline enema on body-temperature, introduced by the equipment for contrast enema. The bottle o f normal saline was hung up 1 m over the examination desk. We needed few liters of saline to replace lost liquids due to the incomplete occlusion of rectum. Meanwhile we monitored the moving of the intussusceptum back into the proximal direction. Criteria for a succesful reduction were the disappearance of the intussusceptum and the passage of fluid through the ileocecal valve. Results. Success was proven in all three girls. No complications occured and the pain relieved immediately after the procedure. There were no signs of intussusception on sonography after 2 and 12hours. We saw a slightly edematous wall of ileocecal valve and terminal ileum. Due to their exellent clinical conditions they were discharged from hospital after a second sonography.

Ultrasonographic diagnnosis of obstructive ileus in a patient with Meckel's diverticulum = Ultrazvočna diagnostika obstruktivnega ileusa pri bolniku z Meckelovim divertiklom by Alenka Višnar-Perovič( )

1 edition published in 1999 in English and held by 3 WorldCat member libraries worldwide

Introduction. Despite the use of modern imaging techniques, the reliable preoperative assessment of Meckel's diverticulurn and related complications with this rare congenital anomaly of the gastrointestinal tract in adults is uncomrnon. Case presentation. This report presents the case of a 25 year old man who presented with a sudden onset of pain in the right lower abdomen and vomiting. On clinical examination the affected area was tender to palpation which revealed an elastic cylindrical formation situated deeply in the abdomen. Blumberg's sign was positive while the laboratory findings were stillwithin normal limits. An ultrasonography of the abdomen revealed an ileocaecal fluid collection containing thicker residue, which was suspicious for Meckel's diverticulum or a duplication cyst and ileus of the small bowel proximally from the formation described. Native radiogram of the abdomen in supine position has confirmed the presence of obstructive ileus at the level of the distal part of the small bowel. Surgery revealed an ileus and compression of the distal part of the small bowel due to the presence of an edematous Meckel's diverticulum. Conclusion. In view of the frequent use of ultrasonography in the evaluation of acute ahdomen, the diagnostic procedures could be rationalized and the time to surgery reduced if possible complicatioris due to Meckel's diverticulum would he considered in the differential diagnosis
Adhezijski ileus = Adhesions and intestinal obstruction by Marko Sever( )

1 edition published in 1997 in Slovenian and held by 2 WorldCat member libraries worldwide

Izhodišča. Prikazana so napogostejša bolezenska stanja in ostali dejavniki, kivplivajo na nastanek prirastlin in ileusa. Poleg anamneze in klinične slike sta UZ in RTG abdomna pomembni diagnostični preiskavi. Bolniki in metode. V letih od 1991 do 1994 je bilo operiranih 30 bolnikov z adhezijskim ileusom. Pri desetih bolnikih smo morali poleg adheziolize narediti še segmentno resekcijo ozkega črevesa. Deset bolnikov (33,3%) je bilo že prej operiranih zaradi adhezijskega ileusa. Zaključki. Ustrezna operativna tehnika, izbira šivalnega materiala in izogibanje dejavnikom, ki povzročajo adhezije, lahko prepreči marsikateri ileus
Clinical importance of portal venous gas detected by abdominal sonography : a report of two cases = Klinični pomen odkritja plina v portalnih venah jeter pri ultrazvočnem pregledu trebuha : prikaz dveh primerov by Primož Gregorič( )

1 edition published in 2004 in English and held by 2 WorldCat member libraries worldwide

Izhodišča. Dokaz plina v veni porte je ponavadi znak resnega obolenja v trebuhu in pomeni slabo prognozo. Z napredkom ultrazvočne diagnostike v zadnjih letih odkrijemo zrak v portalni veni tudi kot prehoden pojav brez kliničnih posledic in sicer pri topi poškodbi trebuha in nekaterih diagnostičnih in terapevtskih postopkih. Prikaz primerov. Predstavljamo dva bolnika. Obema smo pri ultrazvočni preiskavi trebuha odkrili znake plina v portalnih venah, potek bolezni pa je bil diametralno nasproten. Prvi bolnik jebil star 70 let. Utrpel je infarkt mezenterija, čigar posledica je bil plin v portalnih venah. Umrl je nekaj ur po prihodu v bolnišnico. Drugi bolnik je bil star 26 let. Poškodovan je bil kot voznik v prometni nesreči. Med hospitalizacijo je bil klinično stabilen in ni potreboval invazivnega zdravljenja. Ugotovili smo, da se je pojavil plin v portalni veni prehodno zaradi tope poškodbe trebuha. Zaključki. Ultrazvočna preiskava trebuha z uporabo Dopplerja je občutljiva in specifična metoda za dokaz plina v portalnih venah. Z ultrazvočno preiskavo lahko tudi odkrijemo obolenje v trebuhu, ki je vzrok za ta pojav in skrajšamo čas do potrebnega zdravljenja. Če z ultrazvočno preiskavo ne odkrijemo jasnega vzroka za plin v portalnih venah, se moramo o nadaljnih, potencialno nevarnih diagnostičnih in terapevtskih postopkih odločati glede na klinično sliko, ker je pojav plina v portalnih venah lahko tudi prehodnega značaja

Strictures of the male urethra: how to perform and evaluate radiourethrography and sonourethrography to avoid mistakes = [Zožitev moške sečnice: pravilna izvedba in vrednotenje radiografske in ultrazvočne uretrografije, da se izognemo napakam] by Darja Babnik-Peskar( )

1 edition published in 2000 in English and held by 2 WorldCat member libraries worldwide

Introduction. Precise evaluation of the uretheral stricture localisation, length, depth and quality of wall changes are necessary for the selection of the optimal treatment to prevent recurrences. Decision for urethral dilatation, internal urethrotomy or open surgery depends on urethroscopic, radiourethrographic-RUG, and recently, according to MC Annich, also sonourethrographic-SUG results. SUG adds information about the depth and density of spongiofibrosis. Previously published findings of RUG length underestimation, compared to SUG and endoscopy, were responsible for inappropriate treatment and recurrences. In our article, we evaluate SUG as a new imaging method in the diagnosis of uretheral strictures and treatment planning, and describe both imaging methods together with usual pitfalls in performance or interpretation, possible reason for incorrect length measurements, and RUG length underestimation. Patients and methods. In the period of 20 months, we evaluated SUG compared to RUG and endoscopy in 51/130 males with suspected urethral strictures. Results. Compared to RUG, sonographywas correct in 92% radiographycally detected strictures. Length measurements by sonography were 22% shorter than radiographic lengths, which could be explained by radiographic magnification, as it was proved with wire measure placed on penis. Considering radiographic magnification, we did not find important differences in any measurement. Opposite to previously published RUG results compared to endoscopy and SUG, radiographic length underestimation was not found. Conclusions. The combination of both imaging methods provides optimal information about urethral stricture anatomy. We conclude that published radiographic length underestimation could be only a misinterpretation. (Abstract truncated at 2000 characters)

Comparison of radiographic and sonographic urethrography for assessing urethral strictures by Darja Babnik-Peskar( )

1 edition published in 2004 in English and held by 1 WorldCat member library worldwide

The aim of this study was to compare radiourethrography (RUG) and sonourethrography (SUG) for assessment of urethral strictures and to evaluate whether RUG underestimates stricture length, as has been reported. Fifty-one men with suspected urethral strictures were evaluated by both methods performed consecutively. Stricture lengths and diameters measured by RUG were significantly greater (mean 22%, 30%) than those measured by SUG because of radiographic magnification. Both methods, however, detected a similar percentage lumen reduction and similarly graded stricture severity. Equally significant non-correlation between both methods for length measurements in the bulbar and penile urethra (p<0.001, R(2)=0.33 and 0.34, respectively) supported radiographic magnification. Previous inaccuracies appear to relate to RUG measurements of the central tight stricture (mean 44% of the entire length in our series), not the full stricture length. Use of sonographic contrast medium intra-urethrally improved the definition of long narrow strictures. The SUG gave information about peri-urethral tissues not provided by RUG. Once radiographic magnification was taken into account, there were no major differences in the assessment of urethral strictures by both methods. With correct measurement methods, RUG does not underestimate stricture length. For full assessment, the combination of RUG and SUG, which gives information about peri-urethral disease, is optimal in many patients

Transabdominalni in transperinealni ultrazvočni pregled pri karcinomu prostate = Transabdominal and transperineal ultrasonographic evaluation of prostatic carcinoma by Alenka Višnar-Perovič( )

1 edition published in 1995 in Slovenian and held by 1 WorldCat member library worldwide

Basic problems of diagnostic evaluation of prostatic carcinoma are presented. Diagnostic limitations of the transabdominal and transperineal ultrasound and it's role in TNM classification are underscored. Both approaches are complementary diagnostic procedures, and are only able to help in the differentiation of the advanced disease. transabdominal and transperineal ultrasound is not a part of an early diagnostics or screening for the prostatic carcinoma

Ugotavljanje prikritih področnih zasevkov karcinoma glave in vratu z ultrazvočno vodeno aspiracijsko biopsijo = Ultrasound-guided aspiration biopsy of head and neck carcinoma subclinical regional metastases by Aleksandar Aničin( )

1 edition published in 2000 in Slovenian and held by 1 WorldCat member library worldwide

We tested the reliability of ultrasound combined with ultrasound guided aspiration biopsy (USGAB) and the usefulness of lymph node size parameters forthe detection of subclinical neck metastases. In 77 patients with squamous cell carcinomas of the head and neck, 121 neck sides with no palpable regionalmetastases were examined by ultrasound. Depending of the results obtained, ultrasound-guided aspiration biopsy was performed on 64 neck sides. Following surgery, the overal results of ultrasound - ultrasoundguided aspiration biopsy were compared with the histological findings of the dissected lymph nodes. The study showed a 77 % sensitivity, 100 % specificity and 95 % accuracy of ultrasound and ultrasound-guided aspiration biopsy. The negative predictive value was 94 %, and the, positive 100 %; the most reliablelymph node size parameter was the ratio of transversal to longitudinaldiameter. The results of this study showed that ultrasoundguided aspiration biopsy is an appropriate method for the detection of subclinical regional neck metastases

Ultrazvočna diagnostika žočnika in žolčevodov = Ultrasound diagnostics of the gallbladder and the biliary tree by Alenka Višnar-Perovič( )

1 edition published in 2003 in Slovenian and held by 1 WorldCat member library worldwide

Tecnological advances, increased experience and the wide availability of the state of the art machines made ultrasound diagnostics an indispensable tool inthe depiction of almost any kind of condition affecting the gallbladder and the bile ducts. Ultrasonography now plays a broader role not only in the diagnosis but also in the treatment of numerous diseases as an adjunct in the interventional radiology department. It is not only the bedside procedure of the highest flexibility and unlimited follow ups, it is now an evolving technique that extends to the intraductal, endoscopic and intraoperative fields. Ultrasonography has been reported to be very specific in biliary investigations with a liitle lower sensitivity, is effective and low cost investigation
