Risk Factors of Complications after CT-guided Percutaneous Needle Biopsy of Lumps Near Pulmonary Hilum

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%）. ？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.

Liver Abscesses in General Surgery at CsRef CI in Bamako Mali

Liver abscesses correspond to a newly formed cavity created by necrosis of the liver parenchyma induced by the pathogen. The aim of the present work was to study liver abscesses;determine the frequency;describe the clinical and paraclinical aspects, therapeutic and evolutionary modalities;determine the follow-up of treatment in order to assess the cost of treatment in the Reference Health Center of Commune I of Bamako in Mali. This prospective study, involving 30 cases of liver abscess, took place over a period of 24 months from January 2015 to December 2016 in the general surgery department of the Cs Ref of commune I. The liver abscess is very often the consequence of amoebiasis which is rampant in the underprivileged population and it remains topical in surgical practice in Mali. Our hospital frequency was 0.081% with an average age of 34.40 years and extremes of 16 and 61 years;a sex ratio of 2.3 in favor of men. The main clinical signs were fever (56.7%), hepatalgia (73.3%) and hepatomegaly (26.7%). Hepatic collections objectified on abdominal ultrasound were located in the right lobe in 70% of cases and unique in 62%. Amebic serology carried out in 100% was negative in 20%;10% of cases had undergone surgical treatment. The consequences were simple for all our patients. The average cost of care, approximately 100,000 FCFA, was significantly higher than the minimum wage (28,460 FCFA) in Mali.
