OBJECTIVESTo probe into the complications of prostate biopsy.

METHODSThe clinical data of 220 patients underwent prostate biopsy from 1997 to 2001 were reviewed.

RESULTSA total of 93 patients suffered slight complications, and 15 patients suffered severe complications.

CONCLUSIONSTransrectal prostate biopsy is easily and safely by using 18 gague biopsy needles. These data demonstrate the low morbidity and less complication associated with contemporary transrectal prostate biopsy.

The diagnostic value of core needle biopsy is increasingly being preferred because of its better characterization of benign and malignant lesions and lower frequency of insufficient samples. The aim of this study was to determine the diagnostic accuracy and complication rates with 2 different gauges of core biopsy needle in the preoperative diagnosis of palpable breast lumps. A total of 150 consecutive core biopsies were included in this prospective non-randomised study of palpable breast lump from May 2000 to May 2001. The tissue diagnosis made from the core biopsy specimen was compared with the final histopathology reports from the excised specimen. However, if the lump is not excised, a presumptive diagnosis of benign lesion was made only after at least 6 months follow up with no change in the breast lump. The data were analysed for sensitivity, specificity, predictive values, diagnostic accuracy and complications. The results from the 2 different sizes of core needle biopsies were compared accordingly and a statistical analysis was performed using Chi-squared test. Ninety-six core specimens were acquired with 14 G needle while the other 54 with 16 G needle. There was no significant statistical difference between the accuracy of both needle sizes. However, 4 complications occurred with the larger size 14 G needle while none with the 16 G needle, but this was not statistically significant. In conclusion the size 16 G core biopsy needle provided an accurate diagnostic reliability that is comparable to the larger size 14 G needle in the preoperative diagnosis of palpable breast lump.

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.

Percutaneous liver biopsy is well established for the diagnosis and follow-up of many liver diseases. Although it is rather safe, major complications, such as bleeding into the peritoneal or thoracic cavity, hemobilia, enteric perforation and intrahepatic hematoma, have been reported related to the procedure. Recently, incidence of such major complications has been decreased since the introduction of ultrasonography-guided liver biopsy. We report a case of 59-year-old female patient with acute cholecystitis secondary to hemobilia 2 days after ultrasonography-guided percutaneous liver biopsy.

Ultrasound (US)-guided fine needle aspiration (US-FNA) has played a crucial role in managing patients with thyroid nodules, owing to its safety and accuracy. However, even with US guidance, nondiagnostic sampling and infrequent complications still occur after FNA. Accordingly, the Task Force on US-FNA of the Korean Society of Thyroid Radiology has provided consensus recommendations for the US-FNA technique and related issues to improve diagnostic yield. These detailed procedures are based on a comprehensive analysis of the current literature and from the consensus of experts.

OBJECTIVETo evaluate the clinical value of the four regions 12-core systemic prostate biopsy.

METHODSNinety-one patients suspected of prostate cancer received four regions 12-core systemic prostate biopsy, and the detection rate and complications were compared with those of the sextant method.

RESULTSMore positive results were obtained in detecting prostate cancer with the four regions 12-core method, and the complications were similar to those of the sextant biopsy.

CONCLUSIONThe four regions 12-core biopsy was suggested for patients suspected of prostate cancer with enlarged prostate gland above 40 ml.

The factors influencing the incidence of common complications (pneumothorax and pulmonary hemorrhage) of CT-guided percutaneous needle biopsy of lumps near pulmonary hilum were investigated. CT-guided percutaneous needle biopsy of lumps near pulmonary hilum was performed on 48 patients. The complications of pneumothorax and pneumorrhagia as well as the contributing factors were analyzed statistically. The major complications associated with CT-guided needle biopsy included pneumothorax (13 cases, 27.1%) and pulmonary hemorrhage (14 cases, 20.24%). χ(2) test revealed that pneumothorax was associated with the lesion size and depth of needle penetration, and pulmonary hemorrhage with the depth of needle penetration and needle retention time with a significant P value. Pneumothorax was observed in 7 cases (17.5%) out of 40 cases with diameter of mass greater than 3 cm, and in 6 cases (60%) out of 10 cases with depth of needle penetration greater than 4 cm. Additionally, pulmonary hemorrhage was identified in 12 cases (41.4%) out of 29 cases with needle retention time longer than 15 min, and pulmonary hemorrhage in 7 cases (70%) out of 10 cases with depth of needle penetration greater than 4 cm. CT-guided percutaneous needle biopsy of lumps near pulmonary hilum is safe and effective. The key factors to prevent the complications include correct evaluation of lesion size, depth of needle penetration and the needle retention time before the operation.

INTRODUCTIONThere are limited data on the use of endosonography-guided fine-needle aspiration (EUS-FNA) to determine the nature of left adrenal lesions. We described our experience in performing EUS-FNA of left adrenal lesions.

CLINICAL PICTUREDuring a 20-week period, data on consecutive patients who underwent EUS with or without EUS-FNA were prospectively captured. Patients with a left adrenal mass and who underwent EUS-FNA formed our study population.

TREATMENTEUS-FNA.

OUTCOMEA total of 119 consecutive patients underwent diagnostic EUS +/- FNA, during which the left adrenal gland was routinely examined. Twelve of these patients underwent EUS as part of lung cancer staging and among these 12 lung cancer patients, 2 had left adrenal masses detected by computed tomography (CT). EUS detected left adrenal nodules in 2 other patients which were not visualised by CT. The overall prevalence of a left adrenal mass was 3.4%; in the subgroup with confirmed lung cancer, the prevalence was 33.3%. All 4 patients were male, with a mean age of 76.3 years (range, 67 to 87). The mean size of the left adrenal lesion was 30.4 mm (range, 9 to 84.8). EUS-FNA of the left adrenal lesions was performed under Doppler guidance. The mean number of needle passes was 2 (range, 1 to 4). A cellular aspirate was obtained in all patients. No procedural complications occurred. Metastatic non-small cell lung cancer was diagnosed in 2 patients, including a lesion missed on CT. For the other 2 cases, EUS-FNA revealed benign adrenal cells.

CONCLUSIONSEUS-FNA appears safe and useful for the evaluation of left adrenal masses.
