Gynecological laparoscopic surgery using abdominal wall-lifting methods could avoid the deleterious effects of CO(2) pneumoperitoneum, and reduce the stress response. The lowest stress response was found when abdominal wall-lifting methods were used with the patient under epidural anesthesia.

Background and Objectives:Convincing evidence supporting the use of magnetic resonance imaging (MRI) as an effective tool for evaluating cervical sagittal alignment is lacking. This study aims to analyze the differences and correlations between cervical sagittal parameters on x-ray and MRI in patients with cervical disc herniation and to determine whether MRI could substitute for cervical x-ray for measurement of cervical sagittal parameters.Methods:One hundred forty-three adults with cervical disc herniation were recruited. Each patient had both an x-ray and MRI examination of the cervical spine. The cervical sagittal parameters were measured and compared on x-ray and MRI including: C2–C7 Cobb angle, C2–C7 sagittal vertical axis (C2–C7 SVA), cervical tilt (CT), T1 Slope (T1S), and neck tilt (NT). The data were analyzed using a paired-samples t test, a Pearson correlation test, and linear regression.Results:The values of C2–C7 Cobb angle, C2–C7 SVA, CT and T1S on X-ray were larger than those on MRI (P < .05) and NT on X-ray was smaller than that on MRI (P < .05). Each of the cervical sagittal parameters had a significant correlation with the corresponding one on MRI (r = 0.699, 0.585, 0.574, 0.579 and 0.613, respectively) (C2–C7 Cobb MRI = 0.957 + 0.721 C2–C7 Cobb X, C2–C7 SVA MRI = 6.423 + 0.500 C2–C7 SVAX, CT MRI = 3.121 + 0.718 CTX, T1S MRI = 7.416 + 0.613 T1SX, NT MRI = 22.548 + 0.601 NTX).Conclusion:Although MRI and x-ray measurements of cervical sagittal parameters were different, there were significant correlations between the results. MRI could be used to evaluate the sagittal balance of the cervical spine with great reliability.

BackgroundThe purpose of this study was to define the ultrasound imaging characteristics of adrenal tumors and to assess the performance of ultrasound in differentiating benign ‘leave-alone’ lesions from suspicious lesions.Material/MethodsWe enrolled 882 patients in this study. The nature of each lesion was determined by histopathology. Ultrasound finding of each lesion was compared with its corresponding histopathologic result. The final study group consisted of 911 adrenal masses in 882 patients. All images were reviewed by 2 experienced investigators in a double blind manner.ResultsThere were 553 adenomas identified in the study, which constituted 60.70% of the lesions. There were 161 pheochromocytomas (17.67%), 49 myelolipomas (5.38%), 39 cysts (4.28%), 37 metastasis (4.06%), 35 ganglioneuromas (3.84%), 22 lymphomas (2.41%), and 15 cortical carcinomas (1.65%). The sensitivity, specificity, and accuracy of ultrasound-based diagnosis were 89%, 99%, and 93.9%, respectively. A positive predictive value of 90.9% and a negative predictive value of 94.2% were obtained in this study.ConclusionsThis large-sample study showed that ultrasound was a reliable method in differentiating benign ‘leave-alone’ lesions from suspicious lesions.

This study aimed to investigate the perioperative analgesic effect of a buprenorphine transdermal patch in patients who underwent simple lumbar discectomy.In total, 96 patients were randomly divided into parecoxib intravenous injection (Group A), oral celecoxib (Group B), and buprenorphine transdermal patch groups (Group C). The pain status, degree of satisfaction, adverse effects, and condition in which the patient received tramadol hydrochloride for uncontrolled pain were recorded on the night before surgery, postoperative day 1, postoperative day 3, and postoperative day 5.The degree of patient satisfaction in Group C was higher than that in Groups A and B, with minimal adverse effects.The buprenorphine transdermal patch had a better perioperative analgesic effect in patients who underwent simple lumbar discectomy.
