Objective To compare the value of contrast-enhanced ultrasonography (CEUS) with that of laparoscopic ultrasonography (LUS) in localization diagnosis of insulinoma. Methods Thirty-three patients with insulinoma,who received operation, were retrospectively reviewed. All cases were examined by both CEUS and LUS before the tumor removed. Both imaging modalities in diagnosis of insulinoma were analyzed. Results By this study the sensitivity and accuracy of CEUS were 92.31% and 90.0% respectively. Those of LUS were consistent with pathologic findings completely. The accuracy of CEUS was not different with that of LUS (χ2 = 4.21, P = 0. 04). Conclusions CEUS can be used for location diagnosis of insulinoma. For the patients expecting laparoscopic treatment, combination of CEUS with LUS will be suggested before insulinoma is removed.

Objective To evaluate percutaneous injection of hemostatic agents under the guidance of contrast-enhanced sonography(CEUS) in controlling hemorrhage from severe splenic trauma. Methods Eight patients with splenic traumas of grade Ⅲ, Ⅳ were consecutively enrolled in this study. Percutaneous injection of hemocoagulase atrox and α-cyanoacrylate was performed by CEUS-guidance in all patients. Ultrasound examination was performed at 1,3,7 and 14 days after focal injection. Vital signs and hemoglobin (Hb) level were recorded. Results After the injection,immediate CEUS demonstrated that active bleeding from the injury sites disappeared. From 30 minutes after the injection arterial blood pressure began to ascend ( P <0. 05), and heart rate decreased to the normal level after the treatment ( P <0.05). Hb decreased at first and then gradually increased to the normal level. Conclusions Pereutaneous injection of hemoeoagulase atrox and α-cyanoacrylate under the guidance of CEUS can effectively control bleeding from a severe splenic trauma. CEUS can be helpful to the diagnosis of the suspected splenic trauma and to ensure hemostatic materials to be injected exactly into injury sites.

BACKGROUND/AIMS: This study investigated the protection provided by gabexate mesylate thermo-sensitive in-situ gel (GMTI) against grade III pancreatic trauma in rats. METHODS: A grade III pancreatic trauma model with main pancreatic duct dividing was established, and the pancreas anatomical diagram, ascites, and serum biochemical indices, including amylase, lipase, C-reactive protein (CRP), interleukin 6 (IL-6), and tumor necrosis factor-α (TNF-α), were examined. The pancreas was sliced and stained with hematoxylin eosin and subjected to terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining. RESULTS: Ascites, serum amylase, lipase, CRP, IL-6, and TNF-α levels were significantly increased in the pancreas trauma (PT) groups with prolonged trauma time and were significantly decreased after GMTI treatment. The morphological structure of the pancreas was loose, the acinus was significantly damaged, the nuclei were irregular and hyperchromatic, and there was inflammatory cell invasion in the PT group compared to the control. After GMTI treatment, the morphological structure of the pancreas was restored, and the damaged acinus and inflammatory cell invasion were decreased compared to the PT group. Moreover, the cell apoptosis index was significantly increased in the PT group and restored to the same levels as the control group after GMTI treatment. CONCLUSIONS: GMTI, a novel formulation and drug delivery method, exhibited specific effective protection against PT with acute pancreatitis therapy and has potential value as a minimally invasive adjuvant therapy for PT with acute pancreatitis.

OBJECTIVETo assess the accuracy of ultrasound-guided 16G and 18G core needle biopsy for detecting ultrasound visible breast lesions with different sonographic features.
METHODSA total of 955 sonographically detected breast lesions examined with ultrasound-guided core needle biopsy (US-CNB) and subsequently surgically excised from July 2005 to July 2012 were retrospectively reviewed. Histological findings of US-CNB and the surgical specimens were analyzed for agreements, sensitivities, false negative rates, and underestimate rates according to different sonographic features.
RESULTSThe pathological results of the US-CNB showed malignant lesions in 84.1%, high-risk lesions in 8.4%, and benign lesions in 7.5% of the samples. The overall agreement rates were 92.4% for 16G CNB and 92.8% for 18G CNB; their complete sensitivities and false negative rates were both 98.6% and 1.4%, respectively; the high-risk underestimate rates and DCIS underestimate rates were 48.0% and 46.2% for 16G CNB vs 53.3% and 41.2% for 18G CNB, showing no significant difference between the two groups (P>0.01). For both 16G and 18G CNB, the agreements were better for mass lesions than for non-mass lesions (P<0.01). For the mass lesions with a diameter no greater than 10 mm, the agreement rates were lower than the overall data (P<0.01). Calcification in the lesions did not affect the agreement rates (P>0.01).
CONCLUSIONUltrasound-guided 16G and 18G CNB are both accurate methods for evaluating ultrasound visible breast mass lesions with a diameter larger than 10 mm.
