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.
Objective To discuss the diagnostic value of multidetector CT(MDCT) on encapsulated fat necrosis after operation of abdominal cancer, and to investigate the key differences of CT features between encapsulated fat necrosis and postoperative recurrence or metastasis. Methods CT data of 36 patients with encapsulated fat necrosis after operation of abdominal cancer, who received CT in our hospital between Feb. 2012 to May. 2014 during followed-up were retrospectively analyzed, for the purpose of summarizing the CT characteristics. In addition, the clinical presentation, level of carcinoembryonic antigen (CEA) and CA-125 before and after operation were also taken into account, to explore the difference between encapsulated fat necrosis with tumor recurrence and metastasis. Results Among the 36 patients who had suffered from encapsulated fat necrosis after operation of abdominal cancer, 3 patients (8.3%) had 2 lesions and the rest of 33 patients (91.7%) had solitary lesion(a total of 39 lesions). All lesions showed non homogeneous masses consistent with the surgery path and surrounded by fat density ring and soft tissue density capsule. The size of most lesions (94.8%, 37/39) decreased over time. All lesions were found slightly enhancement in portal phase. Five patients with postoperative tumor metastasis, 31 patients had no recurrence or metastasis. Among the 5 patients who had postoperative tumor metastasis at the same time, postoperative CEA was positive in 3 patients, and postoperative CA-125 was positive in 2 patient. Among the other 31 patients who had no recurrence or metastasis, the levels of postoperative CEA and CA-125 of 1 patient were unknown, and the postoperative CEA and CA-125 of 27 patients in the rest patients(90.0%, 27/30) were both negative. Most of them had no special clinical symptoms, only a few (1 patient)patient had mild abdominal pain without other associated symptoms. Conclusion CT is a valuable tool to reveal and diagnose encapsulated fat necrosis in postoperative abdominal cancer. Combined CT findings(such as location, shape, and density) with CEA, CA-125, and clinical presentation, that is easy to differ it from postoperative recurrence and metastasis.
