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
Vloga ultrazvočnih preiskav v diagnostiki in zamejitvi tumorjev trebušne slinavke = The role of ultrasound examination in diagnostics and evaluation of dissemination of the pancreatic carcinoma by Alenka Višnar-Perovič( )

1 edition published in 2001 in Slovenian and held by 2 WorldCat member libraries worldwide

In the article the author presents a rewiev of ultrasound in diagnostics and diferential diagnostics of pancreatic tumors. Modern diagnostic possibilities of ultrasound as are Doppler examination, Doppler examination with ultrasound contrast agents, to evaluate vessels and liver parenchyma for metastases, and tissue harmonic imaging, are important in evaluating dissemination and operability of the pancreatic cancer
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

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.

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
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

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

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

Background. Portal venous gas (PVG) can be a sign of serious disease and a predictor of poor clinical outcome. However, it ean also occur as a transient phenomenon with little clinical significance, especially following blunt abdominal trauma and various diagnostic and therapeutic procedures. Case reports. We describe two patients with PVG detected on abdominal sonography, who had very similar sonographic findings but a completely different clinical outcome. The first patient was a 70-year-old man in whom PVG was the consequence of mesenteric infarction; the patient died in hospital shortly after the admission. Our second patient was a 26-year-old man who was injured in a motor vehicle accident. He was clinically stable and needed no aggressivetreatment. PVG proved to be a transient phenomenon that cleared spontaneously within a day. Conclusions. Doppler sonography is a sensitive andspecific modality for the detection of PVG. In patients with a serious underlying disease, sonography can identify the cause of PVG, so that the appropriate therapy may be undertaken without delay. If the aetiology is unclear, the decision to undertake further expensive and potentially harmful diagnostic procedures should be based on the patient's clinical status
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)
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

Background. Studies concerned with the estimation of ultrasound (US) combined with ultrasound-guided aspiration biopsy (USGAB) in the detection of subclinical regional metastases from the planocellular carcinoma of head and neck are promising, but in few cases. Recently, the authors have pointed out the role of lymph node size parameters in order to decide about the use of USGAB. The aim of this study was to test the reliability of US-USGAB for the detection of subclinical regional metastases in patients with planocellular head and neck carcinomas, including the evaluation of lymph node size parameters. Patients and methods. 121 neck sides with no palpable metastases were examined by US in 77 patients with planocellular carcinomas of head and neck. Depending on the results obtained, USGAB was performed on 64 neck sides. After surgery, the results of US-USGAB were compared with histological findings of the dissected lymph nodes. Results. The study showed 77% overall sensitivity of US and USGAB, and 100% specificity, while the versal / longiyudinal diameter was the best predictor of metastatic lymph node involvement. Conclusion. The results of this study established that USGAB is an appropriate method for detection the subclinical regional metastases on neck, and should be included into routine diagnostic work up in the evaluationof the extent of head and necks carcinomas

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

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
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

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
