ObjectiveTo evaluate the clinical value of ultrasound-guided percutaneous co-axial technique in liver tumor biopsy.MethodsThe clinical data of patients who received ultrasound-guided percutaneous co-axial liver tumor biopsy from March 2015 to December 2016 in West China Hospital of Sichuan University were collected to retrospectively analyze the outcomes of biopsy success rate, sampling number, pathology diagnostic rate and incidence of complications.ResultsA total of 150 patients involving 99 males and 51 females were included, with a mean age of 54.9±4.5 years. The mean tumor size was 2.4±1.2cm. The ultrasound-guided liver tumors biopsy success rate was 100% (150/150). The mean sampling frequency was 2.4±0.6 times. Complications after biopsy included mild local pain (37%, 56/150) and bleeding (0.7%, 1/150).ConclusionUltrasound-guided co-axial biopsy is an simple, safe and efficient image-guided biopsy technique which allows multiple sample acquisition and reduces complications.
ObjectiveTo evaluate the value of preoperative risk assessment of papillary thyroid carcinoma with ultrasound for clinic diagnosis and treatment.MethodsThe data of 400 patients with papillary thyroid carcinoma received operative treatment in 2017 were retrospectively analyzed. Recorded and analyzed the ultrasonic risk assessment and postoperative grading of clinic risk assessment, to evaluate coherence and correlation between them.ResultsThere were 400 lesions with an average size of (12.8±8.5) mm. Among 400 lesions, diameter of 214 lesions less than 10 mm, diameter of 178 lesions were between 10 mm and 40 mm, and diameter of 8 lesions were larger than 40 mm. A total of 242 cases had lymph node metastasis and 309 cases had capsule invasion. Clinical and ultrasoud risk assessment was performed on 400 lesions. There were 224 lesions with low risk of clinical risk stratification vs. 111 lesions with low ultrasonic risk, 148 lesions with intermediate risk of clinical risk stratification vs. 270 lesions with intermediate ultrasonic risk, and 28 lesions with high risk of clinical risk stratification vs. 19 lesions with high ultrasonic risk. The consistency of postoperative recurrence risk stratification and preoperative ultrasound recurrence risk stratification was moderate (κ=0.414, P<0.01). In addition, the consistency between ultrasound examination and clinical lymph node metastasis was poor (κ=0.291, P<0.05), and the consistency of invasion of the capsule was moderate (κ=0.402, P<0.05).ConclusionPre- operative evaluation of recurrence risk grading before thyroid ultrasound, focusing on individualized preoperative assessment, the assessment is more detailed and detailed, and is helpful for follow-up treatment and early screening for recurrence risk.
Objective To discuss the nursing measures for thyroid nodule patients who undergo core-needle biopsy (CNB) guided by ultrasound. Methods We retrospectively analyzed the experiences and main points of nursing for 1 900 thyroid nodule patients who underwent CNB guided by ultrasound between June 2010 and May 2014. Results All the 1 900 patients underwent CNB successfully. The nursing time was between 5 and 15 minutes, averaging (8.0±3.7) minutes. Complications included hematoma in 25 patients (1.3%) and needle syncope reaction in 30 patients (1.6%), which were cured through symptomatic treatment. No complications such as nerve injury, anesthesia accident or death occurred. No medical disputes happened due to specimen errors or loss. The success rate of specimen collection was 98.4% (1 870/1 900), and the diagnostic accuracy was 95.3% (1 812/1 900). Conclusions Ultrasonography-guided CNB is a safe and reliable operation with a high success rate, high diagnosis accuracy and few complications. Being familiar with the process of nursing cooperation and correct disposal and transfer of biopsy specimens are crucial for successful CNB in patients with thyroid nodules.
