Adhezijski ileus = Adhesions and intestinal obstruction by Marko Sever( )

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

Background. The authors pointed out the most frequent diseases and other factors which produce development of adhesions and ileus. Besides history of ilness and clinical features, x ray of abdomen, and US are important. Methods and results. In the period from 1991 to 1994 there were 30 patients operated due to adhesional intestinal obstruction. 10 pts had adhesiolysis and segmental resection of small howel. 10 pts (33.3%) were operated earlier due to adhesions. Conclusions. Proper operative techique, selection of suture material and avoidance of factors causing adhesions can prevent many intestinal obstructions

Ultrazvočno vodena aspiracijska biopsija prikritih področnih zasevkov karcinoma glave in vratu = Ultrasound-guided aspiration biopsy of subclinical regional metastases of head and neck carcinoma by Aleksandar Aničin( )

1 edition published in 2000 in Slovenian and held by 2 WorldCat member libraries 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 planocellular carcinomas of the head and neck, 121 neck sides with no palpableregional metastases were examined using US. Depending on the results, ultrasound-guided aspiration biopsy was performed on 64 neck sides. Following surgery, the results of ultrasound - ultrasound-guided aspiration biopsy were compared with the histological findings of the dissected lymph nodes. The study showed a 77% overall 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 reliable lymph node size parameter was the ratio of transversal to longitudinal diameter. The results of this study showed that ultrasound-guided aspiration biopsy is an appropriate method for the detection of subclinical regional neck metastases

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)
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 2 WorldCat member libraries worldwide

Uvod. Kljub uporabi modernih slikovnih tehnik, zanesljiva preoperativna ocena Meckelovega divertikla in z njim povezanih komplikacij te redke prirojene anomalije prebavnega trakta mnogokrat ni mogoča. Predstavitev. Predstavljmo primer 25 letnega moškega, pri katerem se je pojavila nenadna bolečina v spodnjem abdomnu desno. Klinično je bil predel občutljiv na palpacijo, ki je pokazala elastično, valjasto strukturo globoko v trebuhu. Blumbergov znak je bil pozitiven, laboratorijske vrednosti pa v mejah normale. Ultrazvok abdomna je ileocekalno pokazal tekočinsko kolekcijo z gosto vsebino, sumljivo za Meckelov divertikel ali duplikacijsko cisto in ileus ozkega črevesa proksimalno od opisane strukture. Nativni rentgenogram stoje je potrdil prisotnost obstrukcijskega ileusa v distalnem delu ozkega črevesa. Kirurški poseg je odkril ileus in kompresijo distalnega dela ozkega črevesa zaradi prisotnosti edematoznega Meckelovega divertikla. Zaključek. Glede na pogosto uporabo ultrazvoka pri oceni akutnega abdomna, bi lahko racionalizirali diagnostični postopek in skrajšali čas do kirurške intervencije, če bi možne zaplete Meckelovega divertikla upoštevali v diferencialni diagnozi

V članku je predstavljena vloga in mesto ultrazvočne preiskave v razpoznavi inopredelitvi tumorja trebušne slinavke. Predstavljene so tudi najnovejše diagnostične možnosti, kot so: doplerska preiskava, doplerska preiskava z ultrazvočnim kontrastnim sredstvom za oceno žil in prikaz zasevkov v parenhimski fazi specifični za jetrni parenhim ter tkivni dvojno harmonični prikaz, ki so pomembne predvsem pri oceni razširjenosti in oceni operabilnostiraka trebušne slinavke
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
Ultrasound-guided aspiration biopsy of subclinical regional metastases of head and neck carcinoma = [Ultrazvočno vodena aspiracijska biopsija prikritih področnih zasevkov karcinoma glave in vratu]( )

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

Izhodišča. Študije v katerih obravnavajo kombinirano rabo ultrazvoka (UZ) in ultrazvočno vodene aspiracijske biopsije (UZVAB) pri ugotavljanju prikritih področnih zasevkov ploščatoceličnega karcinoma glave in vratu so obetavne, vendar maloštevilne. V novejšem času, pri odločanju za UZVAB, avtorji povdarjajo pomen parametrov velikosti bezgavk. Želeli smo oceniti zanesljivostUZ-UZVAB in parametrov velikosti bezgavk pri ugotavljanju prikritih področnih zasevkov ploščatoceličnega karcinoma glave in vratu. Bolniki in metode. Pri 77 bolnikih s ploščatoceličnimi karcinomi glave in vratu smo z UZ pregledali 121 strani vratu brez tipnih zasevkov. Glede na rezultate smo na 64 straneh vratu opravili še UZVAB. Pooperativno smo rezultate UZ-UZVAB primerjali s histološkim pregledom pri disekciji odstranjenih bezgavk. Rezultati. V raziskavi smo dosegli 77% občutljivost in 100% specifičnost za UZ in UZVAB skupaj, medtem ko je bila natančnost 95%. Negativna napovedna veljavnost je bila 94%, pozitivna pa 100%. Najboljši parameter pri napovedovanju prisotnosti zasevkov v bezgavkah je bilo razmerje prečni / vzdolžni premer. Zaključki. Menimo, da je metoda UZVAB primerna za diagnostiko prikritih področnih zasevkov na vratu in jo kaže uvrstiti med rutinske preiskave za oceno razsežnosti karcinomov glave in vratu
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 2 WorldCat member libraries worldwide

Izhodišča. Invaginacija je najpogostejši vzrok črevesne obstrukcije pri otrocih, mlajših od dveh let. Proksimalni del črevesa in njegov mezenterij (intususceptum) se uvihata v distalni del (intususcipiens), nato ju peristaltika vleče naprej, pri čemer se komprimira mezenterialno žilje. Najpogostejša je ileokolična invaginacija. Diagnozo lahko postavimo z irigografijo ali ultrazvokom. Ultrazvočni znaki so t.i. kokarda v kokardi, zadebeljena stena z ali brez znakov prekrvavitve ter prestenotična dilatacija z ojačano peristaltiko. Dezinvaginacijo lahko izpeljemo s kontrastnim sredstvom ali z zrakom pod rentgensko kontrolo ali s fiziološko raztopino pod ultrazvočno kontrolo. Bolniki in metode. Pri treh deklicah v starosti 15, 16 in 18 mesecev smo ob tipični klinični sliki ultrazvočno diagnosticirali ileokolično invaginacijo in nadaljevali z dezinvaginacijo pod ultrazvočno kontrolo. S pomočjo sistema za uvajanje barija pri irigografiji smo v široko črevo dovajali fiziološko raztopino, ogreto na telesno temperaturo. Posoda s tekočino je bila 1 m nad preiskovalno mizo. Količina uporabljene tekočine je bila več litrov, ker je zaradi nepopolne okluzije rektuma precej tekočine odteklo. Ultrazvočno smo opazovali potovanje vrha invaginata nazaj v proksimalni smeri. Poseg smo zaključili, ko je izginila tipična slika kokardev kokardi in je prišlo do refluksa tekočine v terminalni ileum. Rezultati. Poseg je bil uspešen in je potekal brez komplikacij pri vseh treh deklicah. Bolečine so takoj po posegu prenehale. Ob kontrolnih pregledih po 2 in 12 urah ni bilo več znakov invaginacije. Nekoliko edematozna je bila stena valvule Bauchini in terminalnega ileuma. Klinično stanje deklic je bilo normalno, tako da so bile odpuščene v domačo oskrbo neposredno po drugi ultrazvočni kontroli. Zaključki. Dezinvaginacija s hidrokolonsonografijo je zaradi visoke učinkovitosti in odsotnosti ionizirajočega sevanja metoda izbora. Zapleti doslej niso opisovani

Sodoben pristop z ultrazvočno preiskavo v diagnostiki kamnov v sečilih = Current approach to diagnosis of urinary stone disease by means of ultrasound by Alenka Višnar-Perovič( )

1 edition published in 1996 in Slovenian and held by 1 WorldCat member library worldwide

The aim of this paper is to assess the value of imaging modalities in the evaluation of patients with suspected renal colic and to suggest a rationale imaging approach for their investigation. As a sensitive test (95%), recently ultrasonography in the well hydrated patient, combined with plain film of the urotract, has been suggested as an alternative to the urography as an initial imaging test. Ultrasound specificity could be improved by measuring the resistibility index using pulsed Doppler method and assessment of the uretericjets with colour Doppler method for evaluation of existence and grade of the suspected obstruction. Urography is indicated only if the plain film, ultrasonographic and Doppler method findings are equivocal or if intervention is necessary

Torzija moda - diagnostika z ultrazvočno preiskavo po doplerju - prikaz primera = Testicular torsion - diagnosis by color duplex sonography - a case report by Dubravka Vidmar( )

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

Introduction. Testicular torsion is a true surgical emergency due to occlusionof the efferent and/or afferent blood vesssels with consequent ishemia following within the next four hours. This condition requires emergencyoperation and can be diagnosed by color duplex sonography which excludes other causes of acute scrotum: inflammation, traumatic testicular rupture and some other rare conditions, which usually do not necessitate surgery. Patient and method. A 29-year old man with a history of sudden and severe right side scrotal pain was admitted to the urology department. After athree day's treatement for orchoepididymitis the condition didn't improve so an US examination was performed. Results. The B-mode image showed an enlarged hypoechogenic and nonhomogeneous right testis. Golor duplex sonography demonstrated a complete absenee of venous and arterial blood flow. The left testis was normaf in the B-mode image and had normal perfusion as well. The diagnosis of torsion was confirmed operatively. Semicastration was performed because testicular viability was eompletely lost. Conclusion. Color duplex sonography is a rapid and effective method to confirm or exclude test-ticular torsion as a cause of acute scrotum. It improves reliability of decision fof prompt surgical correction and prevents semicastration

Basic technique of evaluation of renal mass lesions is presented. Underscored are diagnostic limitations which require complementary diagnostic procedures whose realtionships with sonography are outlined. The analytic criteria of separating mass lesions are reviewed. Experience has shown that sonography could be the first evaluation step in a renal mass detection and differantiation
Ultrazvočna diagnostika pri bolniku z rakom sečnega mehurja = Ultrasound examination in diagnostics of urinary bladder carcinioma by Alenka Višnar-Perovič( )

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

Basic problems of the diagnostic evaluation of urinary carcinoma are presented. Benefits and limitations of transabdominal, transperineal and transurethral ultrasound examination for screening, diagnosis and staging and it's role in TNM classification are discussed. All approaches are complementary diagnostic procedures. Sonography is a sensitive and noninvasivemethod for detection of urinary bladder abnormalities. It should bethe first screening method in patients with macro- or microhematuria. It is possible to detect tumors as small as 2-3 mm. In experienced hands, noninvasive suprapubic sonography gives as good results as invasive intravesical ultrasound and CT for staging of urinary bladder tumours. CT sholuld be used in questionable cases, patients with incontinence and obese patients
