BACKGROUND: Crohn's disease (CD) is routinely evaluated using clinical symptoms, laboratory variables, and the CD activity index (CDAI). However, clinical parameters are often nonspecific and do not precisely reflect the actual activity of CD small-intestinal lesions. The purposes of this prospective study were to compare color Doppler ultrasound (US) findings with histological findings from surgically resected specimens and confirm the hypothesis that color Doppler US can distinguish tissue inflammation and fibrosis...

Turner syndrome, a chromosomal disorder caused by partial or complete absence of one of the two X chromosomes, is characterized by an increased incidence (compared with that in the normal population) of either autoimmune disorders, including chronic inflammatory bowel diseases, or angiodysplasia of the small intestine. Because ultrasonography and color Doppler ultrasound are widely used to investigate gastrointestinal disorders, we decided to carry out an ultrasound-based screening study in patients with Turner syndrome to determine whether this method might be useful in the follow-up of this population...

In the era of double balloon enteroscopy, capsule endoscopy, CT, and MRI enterography is transabdominal ultrasonography (TUS) underestimated method for evaluation of small bowel pathology. As often initial imagine method in abdominal complaints, nowadays has TUS much better diagnostic potential than two decades ago. High-resolution ultrasound probes with harmonic imaging significantly improve resolution of bowel wall in real time, with possibility to asses bowel peristalsis. Color flow doppler enables evaluation of intramural bowel vascularisation, pulse wave doppler helps to quantificate flow in coeliac and superior mesenteric arteries...

BACKGROUND: Ovarian vein thrombosis (OVT) is a rare but potentially serious postpartum complication, which occurs in 0.05% to 0.18% of pregnancies and is diagnosed on the right side in 80% to 90% of the cases. CASE REPORT: A 32-year-old woman presented at 15 days postpartum to our emergency department with severe abdominal pain, fever, and abdominal distension. Abdominal examination revealed right lower quadrant pain with rebound tenderness. The plain abdominal radiography evidenced a diffuse fecal stasis; abdominal ultrasound showed the presence of free fluid in the Douglas' pouch and between small bowel loops...

PURPOSE: The development of stenosis is a typical complication of Crohn's disease and represents a serious diagnostic and therapeutic challenge. The aim of the present study was to define objective quantitative measures of stricture characteristics (fibrostenotic/cicartricial vs. inflammatory) using contrast-enhanced ultrasound (CEUS) in patients with stenotic Crohn's disease. MATERIALS AND METHODS: During a period of 18 months, 18 consecutive patients with Crohn's disease and manifestation of a localized significant small bowel stenosis were prospectively recruited...

Improvements in the ultrasound examination of bowel disease have registered in the last years the introduction of new technologies regarding high frequency probes (US), highly sensitive color or power Doppler units (CD-US), and the development of new non-linear technologies that optimize detection of microbubbles contrast agents responses. Contrast-enhanced ultrasound (CE-US) most importantly increases the results in sonographic evaluation of Crohn disease inflammatory activity. CE-US has become an imaging modality routinely employed in the clinical practice for the evaluation of parenchymal organs due to the introduction of new generation microbubble contrast agents which persist in the bloodstream for several minutes after intravenous injection...

Cavitating mesenteric lymph node syndrome (CMLNS) is a rare complication of celiac disease. Globally, only 36 cases of CMLNS have been reported to date. The present article reports an incidence of its unique pathology and possible complications of celiac disease, followed by a review of the syndrome. A case involving a 51-year-old man with celiac disease who was referred to hospital because of a nontender abdominal mass is described. Plain film x-ray of the abdomen revealed fine curvilinear calcifications in the left lower quadrant...

Intrauterine intestinal volvulus is an extremely rare case of acute congenital intestinal obstruction. The diagnosis is usually possible in the third trimester of a pregnancy. Fetal midgut volvulus is most likely to be recognized by observing a typical clockwise whirlpool sign during color Doppler investigation. Multiple dilated intestinal loops with fluid levels are usually visible during the antenatal ultrasound as well. Physical and radiographic findings in the newborn indicate intestinal obstruction and an emergency surgery is required...

PURPOSE: To study the ultrasound (US) findings and clinical significance of transient small bowel intussusceptions (TSBI) in adults and children. METHODS: Clinical records and US findings of 108 consecutive patients of intestinal intussusception diagnosed on US between August 1995 and August 2004 were reviewed. In all cases, the length, diameter, wall thickness and color Doppler study of the bowel segment involved in intussusception were evaluated. Subsequent follow-up scans were performed at 30 min, 3 days and 2 weeks...

The introduction of biological treatments like monoclonal anti TNF-a antibodies (infliximab), is changing the clinical history of Crohn's disease (CD). The effects of these therapies are monitored emplying clinical indexes of active disease, laboratory parameters, endoscopy and histology, and also with imaging techniques. A new ultrasound contrast agent, SonoVue (Bracco SpA, Milano, Italy), is opening new perspectives in the study of microvasculature of several organs. Aim of this study is to evaluate by SonoVue enhanced ultrasonography (US) the occurrence of modifications in bowel wall microvasculature of CD patients and to correlate them with parameters of disease activity and to follow up the findings during infliximab therapy...

A giant omphalocele is a liver-containing protrusion through an abdominal defect wider than 5 cm in diameter. The giant form with a small abdominal wall defect is a rare condition which, to our knowledge, has not been described previously. We describe three cases with the typical features of elongated vascular liver pedicle and angiomatosis of the hepatic portal system. The abnormal liver organogenesis, due to extra-abdominal development, represented a significant risk factor for hepatic thrombosis after visceral reduction and liver rotation...

Over the past few years, thanks to its ability to reveal neovascularization and inflammatory hyperemia, Doppler sonography has proved to be a valuable method for the assessment of disease activity in inflammatory bowel disease. Hypervascularization has been detected by Doppler imaging both in splanchnic vessels, in terms of flow volume and velocity, or resistance and pulsatility index on spectral analysis, and in small vessels of the affected bowel wall in terms of vessel density. In particular, power Doppler has been shown to be a highly sensitive method for evaluating the presence of flow in vessels that are poorly imaged by conventional color Doppler, and in detecting internal fistulas complicating Crohn's disease...

Intestinal duplication is an uncommon congenital anomaly that often is diagnosed during childhood. Ultrasound diagnosis is based on the presence of a characteristic double-walled cystic mass. We report a case of duplication in a three Month old child presenting with small bowel obstruction. This case is unusual due to the presence of calcifications that are uncommon in intestinal duplication.

Diagnosis and follow-up of Crohn disease (CD) often require invasive instrumental examinations, with a high risk of iatrogenic damage. Ultrasound (US) examination of bowel walls could be the first choice in managing patients with CD. We evaluated the role of tissue color power Doppler (CPD) and B-mode US with intravenous injection of contrast medium in the detection of disease activity. In our series, 52 patients with CD underwent US examination. Each study was completed with tissue CPD and US with intravenous injection of contrast medium (Sono Vue) to evaluate intestinal wall vascularization as an index of disease activity...

BACKGROUND: Spigelian hernia (SH) is a ventral hernia that occurs along the semilunar line formed by the fibrous union of the rectus sheath and the anterior abdominal wall muscles, usually containing small bowel segments, omental fat or both. Spigelian hernias are rare in adults and exceedingly rare in children. A few case reports describing SH in the paediatric population have been published and an association with cryptorchidism has been very rarely reported. OBJECTIVE: To report three examples of SH...

PURPOSE: Mesenteric panniculitis is a rare inflammatory disease. The inflammation produces a lesion which appears as a mass, and normally produces abdominal pain without any other significant clinical signs. The radiological pattern is not typical, but the diagnosis is aided by a number of elements which are important to recognise in order to avoid invasive diagnostic methods or therapy. Six cases are presented, all evaluated with sonography, Color-Doppler US, Spiral CT and Magnetic Resonance Imaging (MRI)...

A 71-year-old woman presented with vomiting, abdominal pain and vague right gluteal discomfort. Abdominal ultrasound showed ascites and dilated small bowel loops with peristaltic movement, while transgluteal ultrasound revealed entrapped ascites beneath gluteal muscles and an oedematous, immobile bowel loop trapped between the sacrum and iliac bone with barely visible colour Doppler flow suggestive of an incarcerated sciatic hernia. CT demonstrated similar findings and subsequent surgery confirmed the diagnosis...
