ObjectiveTo explore the relation between ultrasound images of endometriosis and its clinical symptoms. MethodsChoosing clinical data of 300 patients with endometriosis pathologically diagnosed between January 2009 and January 2014, we retrospectively analyzed ultrasound images and clinical symptoms, using Chisquare test for statistical analysis, and the index P<0.05 was statistically significant. ResultsIn patients with big endometriosis' nidus, the menstrual quantity increased, menstrual cycle prolonged, the incidence of abnormally vaginal bleeding was high (χ2=11.749, P=0.001; χ2=4.847, P=0.028; χ2=5.686, P=0.017). In patients whose endometriosis were located in posterior uterine wall, the menstrual quantity increased, and the incidence of abnormally vaginal bleeding was high (χ2=5.188, P=0.023; χ2=49.691, P<0.001). The size of endometriosis' nidus had nothing to do with dysmenorrhea, constipation and frequent micturition (P>0.05). The position of endometriosis' nidus had nothing to do with menostaxis, dysmenorrhea, constipation and frequent micturition (P>0.05). ConclusionThe size of endometriosis' nidus has a connection with the clinical symptoms of menorrhea, menostaxis and abnormally vaginal bleeding; the position of endometriosis' nidus has a connection with the clinical symptoms of menorrhea and abnormally vaginal bleeding. The results of ultrasonography should be combined with clinical symptoms in diagnosing endometriosis, avoiding missed-diagnosis and misdiagnosis.
ObjectiveTo comparatively analyze the image features of tumorous acute pancreatitis (T-AP) and non-tumorous acute pancreatitis (NT-AP). MethodsSixteen cases of histopathologically proven pancreatic tumors inducing acute pancreatitis and 30 cases of non-tumorous acute pancreatitis were collected, and studied their CT and MRI features. ResultsThere were 16 cases (100%) with focal nodules or masses in T-AP group and none in NT-AP group. The average innerdiameter of main pancreatic ducts in T-AP group was (9.6±6.8) mm, in which 14 cases (87.5%) were dilated. And the average innerdiameter of main pancreatic ducts in NT-AP group was (2.9±0.9) mm, in which 7 cases (23.3%) were dilated. The cases of sinistral portal hypertension (SPH), accompanying cholelithiasis and lymphadenosis between the two groups were 10 (62.5%), 3 (18.8%), 14 (87.5%), and 1 (3.4%), 25 (83.3%), 30 (100%), respectively. The occurrence of manifestation of focal nodules or masses, dilated main pancreatic ducts, SPH, and accompanying cholelithiasis were significantly different (P=0.000) between T-AP and NT-AP groups. While, the differences in enhancement pattern and the occurrence of lymphadenosis between the two groups were not significant (P > 0.05). ConclusionThe image features of T-AP are various. The application of CT and MRI could provide effective diagnostic guidelines for patients with T-AP.
ObjectiveTo compare the functioning time, duration, cervical vascular blood flow and adverse effects of different concentrations of ropivacaine mesylate in performing stellate ganglion block (SGB) under Doppler ultrasound. MethodsA total of 240 patients (grade Ⅰ or Ⅱ classified by American Society of Anesthesiologists) aged between 23 and 62 years old ready to undergo SGB between January and April 2013 were chosen for our research. They were randomly divided into two groups with 120 patients in each. Group A and B received unilateral SGB with 7 mL of 0.239% and 0.596% ropivacaine mesylate respectively. Successful SGB was verified by Horner syndrome. The functioning time, duration, hemodynamic changes, cervical vascular blood flow and adverse effects were recorded and compared. ResultsHorner syndrome was observed in all patients. There was no significant difference in functioning time between the two groups (P>0.05). The duration of functioning was significantly longer in group B than that in group A (P<0.05). No significant difference was found in hemodynamic changes after SGB (P>0.05). No adverse effects were found in both groups. The blood flow of the vertebral artery and the internal carotid artery before the injection and 10 minutes after the injection were not significantly diferent (P>0.05). ConclusionSGB can be induced with 0.239% and 0.596% ropivacaine mesylate. We suggest using 0.596% ropivacaine mesylate by ultrasound-guiding because of the significantly longer functioning duration.
Severe hallux valgus, a triplanar foot deformity significantly impairing patients’ quality of life, has witnessed progressive advancements in surgical management. This article systematically reviews the therapeutic progress through literature analysis, encompassing modifications of conventional surgical procedures and applications of novel techniques and innovative biomaterials. A critical analysis and discussion of these technological advancements and future developmental directions are presented to provide valuable insights and references for clinical management of severe hallux valgus.
ObjectiveTo improve recognization and effect of surgical treatment for solid pseudopapillary tumor of pancreas (SPTP) through multidisciplinary team (MDT) discussion.MethodsThe clinical data of 1 case of SPTP treated in The Second Affiliated Hospital of Chongqing Medical University were discussed by the MDT. The best operation scheme was selected and the patient was followed-up.ResultsThe preoperative CT scan showed that the occupation on the body and tail of pancreas and suggested it was the tumorous lesions. After the MDT discussion, the preoperative diagnosis was still not completely clear. However, the decision was made to resect occupation. After the operation, the pathological examination showed it was the SPTP. There was no recurrence or metastasis with the follow-up of 6 months.ConclusionsPreoperative diagnosis of SPTP is difficult, especially for atypical SPTP. Through MDT discussion, it can help to reduce misdiagnosis rate and formulate optimal surgical treatment strategy.
