BACKGROUND: Malignancies are among the most common causes of death in children. The present study was undertaken to evaluate and compare bone marrow aspiration and unilateral biopsy to detect bone marrow metastases in pediatric patients, using bilateral biopsy as the gold standard. METHODS: During a 6-month period, 63 consecutive newly diagnosed children with confirmed malignant diseases other than leukemia were evaluated for bone marrow metastases or infiltration. Biopsies were obtained from both right and left posterior iliac crests whereas aspiration was performed only at the right crest. Interpretation to the right-side biopsy was considered as the unilateral biopsy result, whereas the bilateral biopsy result was as follows: positively was accepted if one or both of the two-side samples were qualified as positive, while a negative result was considered only if both sides were negative. The bilateral biopsy was considered the gold standard, and sensitivity, specificity, positive and negative predictive value, and false positive and negative rates were computed for the unilateral biopsy and aspiration procedure. RESULTS: We identified bone marrow metastases in 11 (17.5%) patients. The sensitivity was the only significant difference (p <0.05) observed between unilateral biopsy and aspiration. Finally, of the 63 patients, unilateral biopsy was reported as inadequate in one patient (1.6%), while aspiration was inadequate in two (3.2%). CONCLUSION: Unilateral biopsy was better than bone marrow aspiration. However, because bilateral biopsy is the gold standard, we recommend using this and bone marrow aspiration simultaneously to evaluate a pediatric patient with any malignancy potentially infiltrating bone marrow.  相似文献

The diagnostic yield of blind percutaneous liver biopsy is improved when two or three specimens are taken during the procedure by redirecting the needle through a single entry-site, without exposing the patient to a greater risk of complications provided that standard precautions are taken. This study was designed to obtain further data on the safety of this procedure at King Edward VIII Hospital, Durban. During the period 1984-1990 (inclusive) a total of 2,646 biopsies were carried out: a single specimen was obtained in 834 patients, two specimens in 983 patients and three in 829 patients. Complications directly attributable to the procedure occurred in 24 patients who had one specimen, 20 who had two, and 19 who had three specimens taken during the biopsy. A single specimen had been obtained from three of the eight patients who had died, two specimens had been taken from another patient, and three specimens were obtained from the other four patients, i.e. patients in whom two or three specimens were taken did not have a higher incidence of pain, symptomatic hypotension, biliary peritonitis or death than those in whom one specimen was taken. Accordingly, when blind percutaneous needle biopsy of the liver is carried out, two specimens should be obtained by redirecting the needle through a single entry site as this improves the diagnostic yield without increasing complications. The morbidity and mortality associated with liver biopsy in this hospital is, however, high. Good technique, careful monitoring of patients after biopsy and prompt and aggressive resuscitation are essential if the mortality rate is to be reduced.  相似文献

Biopsy specimens of the small bowel were obtained from 40 patients suspected of having malabsorption. Four different techniques were used at a single session--namely, endoscopic biopsy of the descending duodenum using paediatric and standard size forceps and suction capsule biopsy of the descending duodenum and the proximal jejunum. Specimens were compared for size, adequacy, and ability to confirm or exclude mucosal abnormality. Fourteen patients had villous atrophy. In all patients four biopsy specimens were obtained with paediatric endoscopic forceps and four with standard endoscopic forceps. No capsule biopsy specimen was retrieved from the duodenum in three patients and from the jejunum in five patients. Specimens were considered to be adequate in 36 patients when paediatric forceps were used, in 39 when standard forceps were used, in 28 on duodenal capsule biopsy, and in 32 on jejunal capsule biopsy. This study indicates that the most reliable method for diagnosing or excluding villous atrophy is endoscopic forceps biopsy of the descending duodenum, provided that at least four specimens are obtained with standard size forceps.  相似文献

Thoracoscopic lung biopsy is becoming the procedure of first choice for the diagnosis of many localized and diffuse lung diseases. We have performed thoracoscopic lung biopsy for 17 patients with diffuse infiltrative lung disease, in Kurume University Hospital. There were 13 females and 4 males with a mean age of 48 years (range: 19-71 years). Thoracoscopic surgical biopsy was performed in the right lung in 12 and in the left lung in 5. Adequate lung tissue from each case was obtained for pathological examination. The mean surgical biopsy time was 49 min (range: 25-72 min) and bleeding was negligible. The mean duration for chest tube drainage was 2.6 days. No postoperative complication such as prolonged air leakage occurred. A specific diagnosis from the biopsy was achieved in 13 (76.4%) of the 17 cases. In only 6 (35.2%) of the 17 cases, the pathological diagnosis was the same as that from the thoracoscopic biopsy. In these 6 cases, the same diagnosis was obtained only in those with idiopathic interstitial pneumonitis or diffuse panbronchitis. Thoracoscopic lung biopsy was safe and useful for diagnosis for diffuse infiltrative lung disease.  相似文献

Background Anterior mediastinal masses include a wide variety of diseases from benign lesions to extremely malignant tumors. Management strategies are highly diverse and depend strongly on the histological diagnosis as well as the extent of the disease. We reported a prospective study comparing the usefulness of core needle biopsy and mini-mediastinotomy under local anesthesia for histological diagnosis in anterior mediastinal masses. Methods Atotal of 40 patients with masses of unknown histology and located either at or near the anterior mediastinum received biopsy prior to treatment. The diagnostic methods were core needle biopsy in 28 patients and biopsy through mini-mediastinotomy under local anesthesia in 15 patients (including 3 patients for whom core needle biopsy failed to yield a definite diagnosis). Results Histological diagnosis was achieved in 18 of the 28 patients receiving core needle biopsy. Of them, all 4 patients with pleural fibromas and 9 of the 12 patients (75%) with pulmonary mass were diagnosed definitively. In the remaining 12 patients with mediastinal mass, histological diagnosis was achieved in only 5 patients (41.7%). In contrast, biopsy through a mini-mediastinotomy failed in only 3 patients. In the remaining 12 patients with huge mediastinal masses, who underwent mini-mediastinotomy, a definitive histological diagnosis was reached by pathological and/or immunohistochemical study (diagnostic yield 85.7% in 12 of 14 cases of mediastinal mass, P=0.038 vs core needle biopsy). For the 9 patients with thymic epithelial tumors, the diagnostic yield was 40% (2 in 5 cases) for core needle biopsy and 83.3% (5 in 6 cases) for mini-mediastinotomy. There was no morbidity in patients receiving mini-mediastinotomy. In the 30 patients with biopsy-proven histological diagnosis, the results contributed to therapeutic decision making in 25 cases (83.3%). Conclusions Core needle biopsy is effective in the diagnosis of pulmonary and pleural diseases. Yet its diagnostic yield in mediastinal mass is rather low. Superior to core needle biopsy, biopsy through a mini-mediastinotomy under local anesthesia is highly effective in the histological diagnosis of anterior mediastinal mass, and has a satisfactory diagnostic yield. The method is safe, minimally invasive, cost-effective, and useful in therapeutic decision making for anterior mediastinal masses.  相似文献
