This paper reviews the complications that arose after 68 276 percutaneous liver biopsies performed from 1973 to 1983. The complications are analyzed in relation to the underlying liver disease and to the type of needle used. Death was infrequent (9/100 000); it was always due to haemoperitoneum and occurred only in patients with malignant diseases or cirrhosis. Complications were less frequent in AVH (44/100 000) than in other liver diseases (from 125 to 278/100 000). Death, serious haemorrhagic complications, pneumothorax and biliary peritonitis were more frequent after biopsy with the Trucut needle than after biopsy with Menghini's needle (3/1000 against 1/1000). Sixty-one percent of complications were discovered within two hours of biopsy and 96% within one day. The data indicate a post biopsy observation period of at least 24 hours. The day-case procedure should be reserved for patients not presenting liver tumour or cirrhosis.

The previous methods to biopsy renal allografts at our institution involved the use of the Franklin-Silverman or Tru-Cut needles. Unfortunately they had a significant rate of post biopsy bleeding secondary to deep penetration when excess force was used to penetrate a tough transplant capsule. Although spring loaded biopsy devices have been widely used for native kidney biopsies over the past three years, the complication rate for renal allograft biopsies has not been sufficiently evaluated. We describe our experience using a disposable spring loaded biopsy device on transplanted renal grafts. Fifty-four biopsies were performed with the device, all under ultrasound guidance. The ASAP automatic biopsy system by Medi-tech was used comprising of a spring loaded gun with a 15 cm long 15 GA needle echogenic tip and 17 mm specimen notch. All patients were ultrasounded immediately post biopsy to look for hematomas. Compared to 55 previous biopsies performed using Tru-Cut needles, we conclude that the ASAP automated biopsy system proved equally effective in obtaining adequate tissue for diagnosis with fewer post-biopsy hematomas compared to traditional biopsy methods.

A retrospective review of 211 computed tomographic (CT)-guided and 58 ultrasound (US)-guided biopsies of pancreatic lesions performed between 1985 and 1989 was undertaken to evaluate the accuracy of diagnosis and the number of complications. Combined CT and US accuracy in the diagnosis of malignancy was 93%. CT-guided biopsies had an accuracy of 86%, and US-guided biopsies had an accuracy of 95%. Accuracy was higher with larger masses (>3.0 cm, 92%;<or = 3 cm, 81%) and larger needle sizes (16-19 gauge, 92%; 20-22 gauge, 85%) and when the mass was located in the body or tail of the pancreas (93%) rather than the head (84%). Major complications developed in three cases (1.1%). No biopsy-related deaths occurred. Needle passage through the gastrointestinal tract, including the colon, did not cause complications.

The authors prospectively analyzed 1,000 biopsies guided with computed tomography (CT) and performed in 955 patients over a 30-month period. All patients were followed up from 3 months to 2 years. The biopsies were performed in an average of 22 minutes (range, 3-85 minutes) by 26 different radiologists; five radiologists performed 547 of the procedures. Of the 1,000 biopsies, 722 were performed in areas in the liver, retroperitoneum, pancreas, pelvis, and adrenal glands. Of 69 errors in diagnosis, 67 were falsely negative and two were falsely positive; 747 true-positive and 184 true-negative diagnoses were made. CT-directed biopsy for accurate diagnosis was 91.8% sensitive and 98.9% specific, with a positive predictive value of 99.7% and a negative predictive value of 73.3%. Of 11 patients with complications, seven had hematomas, three had pneumothorax, and one had hematuria. No deaths occurred, and only one patient required surgery.

Percutaneous Trucut lung biopsy in the diagnosis of localised pulmonary lesions.

In a prospective evaluation of percutaneous Trucut needle biopsy for localised intrathoracic lesions in 89 patients histological specimens were obtained in 81. Malignancy was diagnosed in 66 cases. Subsequently definitive histological reports were available in 18 of these patients with complete concordance of malignant cell type. Sixteen patients had non-malignant histological appearances, which were later confirmed objectively in six. In three patients there was no follow up information, but in the remainder the clinical course was entirely consistent with the histological appearances of the biopsy specimens. Adequate specimens were obtained from only two of the five lesions less than 2 cm in diameter. Lesions deeper than 8 cm from the site of biopsy were associated with significantly more haemorrhagic complications than more superficial lesions. Comparison with other series indicates that Trucut needle biopsy which produces histological specimens has greater diagnostic accuracy than cytological techniques for both malignant and non-malignant localised lesions. It is concluded that this technique has a definite place in the investigation of this common problem in carefully selected patients provided that strict attention is paid to the details of the technique.

Operative biopsy of the pancreas using the Trucut needle.

The results of 14 operative biopsies of the pancreas using the Trucut technique are presented. There was no significant complication attributable to the biopsy, and in all cases an adequate tissue specimen was obtained, facilitating either frozen or paraffin section histological diagnosis. One false negative result was obtained which was due to sampling error. This technique is recommended as a good alternative when operative pancreatic biopsy is required. It is technically simple, has an acceptably low sampling error, provides a good tissue specimen for histological examination, and has few complications.

Tru-Cut biopsies were obtained from 52 consecutive patients referred with soft tissue tumours. Forty-five patients had soft tissue sarcomas; seven had benign soft tissue tumours. Of the biopsies 96 per cent provided adequate material for diagnosis. The histological diagnosis made from the Tru-Cut biopsy was compared with that made from the resected specimen. There were no false positive diagnoses of malignancy. The accuracy of Tru-Cut biopsy was 98 per cent for the diagnosis of malignancy and 94 per cent for the diagnosis of sarcoma. Tumour subtype was correctly specified in 85 per cent of sarcomas and tumour grade in 88 per cent. Tru-Cut biopsy should replace open biopsy as the primary means of diagnosis of soft tissue tumours unless a satisfactory tissue sample cannot be obtained.
