The patient felt pain when their sick ovaries were pressed. The position of seven sick ovaries was changed. The pelvic effusion was detected in five cases. The blood flow signal was not demonstrated in all sick ovaries by CDFI and DPI.〖WTHZ〗Conclusion : The ultrasonic imaging characteristics are reliable to diagnose ovarian torsion during the pregnant period.
摘要:目的:探讨盆腔脓肿的临床表现,超声诊断结果及手术探查情况以提高诊疗水平。方法:对2000年1月~2006年12月我科收治的25 例手术治疗的盆腔脓肿病例进行回顾性分析。结果：其临床表现主要为腹痛、发热、腹部或盆腔包块等。超声声像显示:盆腔内不规则囊性或多房性输卵管卵巢肿块,囊内不均质光点,伴有或不伴有盆腔积液。手术探查表现为:盆腔粘连,一侧或双侧输卵管脓肿或输卵管卵巢脓肿。结论:盆腔脓肿的临床表现不典型,术前易出现误诊和漏诊;随着病情的变化,结合临床表现、 阳性体征的发现及超声诊断可以提高其检测率。Abstract: Objective: To explore the clinical symptoms, ultrasonography diagnosis results and surgical treatment results of pelvic abscess, thus to raise the diagnosing standard and treatment level from Jan.2000 to Dec. 2006. Methods: Carries on the review analysis to 25 example feminine pelvic abscess patient’s clinical diagnosis material. Results: The principal clinical symptoms of pelvic abscess are abdominal pain and fever,tissue mass is palpated in the abdomen or pelvic cavity and is detected. Sonographic appearance of the pelvis demonstrated irregular, uniloculated or multiseptated cystic tuboovarian mass with nonhomogenic internal echoes, with or without pelvic fluid collection. Surgical results showed some adhesions in pelvis, uniorbilateral pyosalpinx or tuboovarian complex abscess. Conclusion: The pelvic abscess displays not typically,,there is a comparatively high rate of misdiagnosis and missed diagnosis before the surgical treatment.The rate of missed diagnosis is by mistake high.Unifies the clinical symptoms,the masculine symptom, the auxiliary inspection and the guidance of ultrasound,may raise the diagnosis rate of accuracy.
Objective To systematically review the clinical value of color Doppler ultrasonic for diagnosing female breast cancer. Methods We electronicaaly searched the databases including The Cochrane Library (Issue 2, 2013), EMbase, PubMed, CNKI, WanFang Data, MedaLink ,VIP and CBM for diagnostic tests on breast cancer diagnosed with color Doppler ultrasonic vs. with pathological biopsy (golden criteria) from 1982 to the March, 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies according to QUADAS items. The Meta-DiSc software (version 1.4) was used to conduct pooling on sensitivity, specificity, positive likelihood radio, and negative likelihood radio. Heterogeneity test was performed and the summary receiver operating characteristic curve (SROC) was drawn for area under the curve (AUC). Results A total of 25 studies involving 3 274 patients were included. The results of meta-analysis showed that, SPE, SEN, +LR, −LR and DOR were (0.76, 95%CI 0.74 to 0.78), (0.80, 95%CI 0.78 to 0.82), (3.58, 95%CI 2.63 to 4.87), (0.28, 95%CI 0.22 to 0.35) and (13.76, 95%CI 8.47 to 22.36), respectively. The AUC of SROC curve was 0.865 7. Conclusion Current evidence shows that color Doppler ultrasonic has high sensitivity (80%) and high specificity (76%) in the diagnosis of high-frequency Ultrasound. The positive rate in the breast cancer group is 13.76 times as high as that in non-breast cancer, which indicates color Doppler ultrasonic has good diagnostic value for breast cancer.
ObjectiveTo evaluate the value of high-frequency color Doppler ultrasonography in the diagnosis of femoral hernia. MethodsThe ultrasonographic features of 39 femoral hernias in 37 patients treated between March 2008 and October 2013 were retrospectively analyzed, and the results were confirmed by surgery. ResultsThirty-nine femoral hernias were diagnosed by surgery, including 19 in the right side, 16 in the left side, and 2 with double-side hernias. Thirty-seven femoral hernias were diagnosed with ultrasonography. Two femoral hernias were misdiagnosed as lipoma in one, and as enlarged lymph nodes in one, respectively. Ultrasound diagnosis accurate rate was 94.9% (37/39). Hernia content could be seen through surgery in 28 cases, and the ultrasound accurate rate in assessing the hernia content was 85.7% (24/28). ConclusionUltrasonography is the first choice for improving the diagnosis efficacy of femoral hernia.
ObjectiveTo evaluate the value of ultrasound in the differential diagnosis of thickened bowel wall at the lower quadrant of abdomen. MethodsThe ultrasonic and clinical data of 416 cases of bowel wall thickening at the lower quadrant of abdomen were retrospectively analyzed between January 2009 and April 2013 in Meishan Traditional Chinese Medicine Hospital, Meishan Chinese Railway Hospital and West China Hospital of Sichuan University. The diseases included appendicitis, periappendiceal abscess, Meckel's diverticulum, intestinal duplication, Crohn's disease and intestinal tuberculosis. Misdiagnoses were also analyzed. ResultsAmong the 416 patients, there were 304 cases of inflammation, 90 of tumors, and 22 of congenital diseases. On ultrasound images, they manifested as cystic mass in 19 cases, mixed solid and cystic mass in 77 cases, and solid mass in 320 cases. Of all the cases, there were 56 cases of diffused changes, 54 of multiple-segment changes, and 306 of focal changes. ConclusionUltrasound is a valuable diagnostic imaging tool in the differential diagnosis of bowel thickening diseases at the lower quadrant of abdomen.
