Objective: To study the diagnostic value of immediate color Doppler ultrasonography on traumatic hepatic hemorrhage after tissue sampling with ultrasound-guided liver biopsy and the clinical effect of its-directed local compression hemostasis at puncture-site. Methods: 132 hospitalized patients with various liver diseases underwent ultrasound-guided hepatic puncture-biopsies, including 61 cases with diffuse parenchymal and 71 cases with focal liver lesions. Immediate postoperative color Doppler ultrasonography was performed following liver biopsy. Abnormal blood flow signal was observed at hepatic puncture biopsy site, and if there were hemorrhagic signals, ultrasound-directed local compression hemostasis was performed until the bleeding signal disappeared. F-test and Chi-square test were used for statistical analysis. Results: Immediate color Doppler ultrasonography showed traumatic hemorrhage in 36.1% (22/61) and 40.8% (29/71) cases of diffuse liver disease and focal liver disease group, respectively. All hemorrhagic signals were eventually disappeared after ultrasound-directed local compression hemostasis. The median hemostasis time was 2 min in both groups, and there was no statistically significant difference in bleeding rate and hemostasis time between the two groups (P>0.05). There were no serious complications and deaths. Conclusion: Traumatic hepatic hemorrhage along the needle puncture tract is a common accompanying condition during liver biopsy. Immediate postoperative color Doppler ultrasonography can trace bleeding signals in timely manner and direct effective compression hemostasis, so it should be used routinely to help avoid occurrence of severe hemorrhagic complications.

Percutaneous liver biopsy is valued in the diagnosis of diffuse or localized liver disease. Serious complications after ultrasonography-guided liver biopsy are rare. We report a case of a 69-year-old man who underwent a percutaneous liver biopsy for the evaluation of his underlying liver disease with subsequent late complication of intraluminal gallbladder hematoma.

PURPOSE: Gynecomastia, a benign enlargement of the male breast due to proliferation of the glandular component, is a common clinical condition with various causes. This study investigates the changes of serum sexual hormones levels and the causes of patients with gynecomastia. METHODS: The conditions associated with gynecomastia were evaluated in 68 gynecomastia patients. The levels of serum estradiol (E2), and testosterone (T), and the estradiol to testosterone (E2/T) ratio were measured in 37 of these 68 subjects along with 10 healthy male controls. Ultrasound for the adrenal gland and liver diseases, liver function test, and physical examination or ultrasound for testicular pathology were also performed. RESULTS: The most common cause of gynecomastia was idiopathic (50.0%). The conditions associated with gynecomastia were drugs (23.5%), hormone (10.3%), and various associated diseases (16.2%) including liver diseases (8.8%), chronic lung diseases (4.4%), lung cancer (1.5%) and chronic renal failure (1.5%). The levels of E2 and T, and the E2 to T ratio in the control group were 35.3+/-3.9 pg/ml, 5.0+/-0.4 ng/ml and 7.1+/-0.5 respectively. Those in the gynecomastia group were 48.7+/-7.1 pg/ml, 4.3+/-0.3 ng/ml and 12.0+/-1.8 respectively. The differences between the two groups for the E2 to T ratio as well as the levels of E and T were not significant, though the average E2 level and the E2 to T ratio in the gynecomastia group were higher than those in the control group. The causes of gynecomastia varied according to the patient age. CONCLUSION: The differences of the E2 to T ratio, and the level of E2 and T in the patients with gynecomastia were not the only cause of gynecomastia, Thus, considerations need to be given to the changes of sexual hormones as well as associated diseases or drugs to enable better understanding of the causes of gynecomastia.
