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.

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 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 summarize the individualized diagnosis and treatment experience in a patient with primary pancreatic diffuse large B-cell lymphoma.MethodsBy muti-disciplinary term (MDT) model, a patient with primary pancreatic diffuse large B-cell lymphoma admitted in the People’s Hospital of Chishui in Dec. 2016 was discussed. The diagnosis, perioperative period management, and operation scheme were carried out by the MDT.ResultsThe patient’s general condition was good. After multidisciplinary discussion in the Department of Radiology, Oncology, Interventional, and Hepatobiliary and Pancreatic Surgery, the patient was considered to have surgical indications. After thorough communication with the patient and family, the patient was selected for surgical resection. The whole operation lasted for 5 hours, and the intraoperative blood loss was about 300 mL. The operation was successfully completed and no complications such as pancreatic fistula occurred after operation. Liquid drainage tube was drawn out at 10 days after opertion, and pancreatic tube stent and T tube were retained. The patient discharged on 13 days after surgery. Subsequently, the patient underwent adjuvant chemotherapy. At present, the patient has been followed up for 1 year, no signs of tumor recurrence and metastasis, and continued follow-up.ConclusionsPrimary pancreatic diffuse large B-cell lymphoma is rare and has a poor prognosis. The main treatment is mutli-mode treatment based on surgical resection combined with chemotherapy.
Abstract: Objective To summarize the clinical experiences of videoassisted thoracoscopic surgery (VATS) lobectomy performed on a series of 300 consecutive patients, and report the results of a 3year followup. Methods We retrospectively analyzed the clinical data of 300 consecutive patients who underwent VATS lobectomy from September 2006 to December 2009 in the Department of Thoracic Surgery, People’s Hospital of Peking University. Of the 300 patients, there were 159 males and 141 females with the age ranged from 18 to 86 years (58.30±13.90 years). Preoperative diagnosis showed that there were 266 patients of mass in the lung, 22 of bronchiectasis, 5 of cyst/abscess in the lung, 3 of pulmonary sequestration, 2 of fungus infection, and 2 of pneumothorax. We assessed the perioperative variables by standard descriptive statistics and estimated the 3year survival rate by KaplanMeier analyses. Results Sixtysix patients were diagnosed to have benign diseases and 234 patients were with malignancies. A percentage of 81.82% (54/66) of the benign patients had infectious diseases, and the majority of the malignancies was nonsmall cell lung cancer (213 patients), especially adenocarcinomas which comprised 73.08% (171/234) of all the malignancies. A total of 273 patients accomplished VATS lobectomy, of whom 27 patients required conversion to thoracotomy at a conversion rate of 9.00%(27/300). In the VATS lobectomy accomplished group, the mean operation time was 317±088 h, and the blood loss was 225.70±195.20 ml. Benign surgery took significantly less time (t=2.280, P=0.0032) and had shorter drainage time(t=1.392, P=0.0304) than those of malignancies. Dense adhesions between lymph nodes and blood vessels was the primary reason for conversion to thoracotomy in 17 patients at a percentage of 62.96%(17/27). Bleeding was the second reason for conversion in 5 patients at a percentage of 1852%. The patients in the upper lobe lobectomy group showed significantly higher risk of conversion compared with those in the nonupper lobe surgery group (χ2=6.131, P=0.013), while gender (χ2=1.182, P=0.277), pathology (χ2=0.210, P=0.647) and the tumor located in left or right side(χ2=2.933, P=0.087) didn’t influence the risk of conversion. The result of the 3year followup showed that there was no reoccurrence of symptoms in patients with benign diseases; Nonsmall cell lung cancer patients had a 3year survival rate of 0.87 with the 95% confidence interval (CI) from 0.77 to 0.96, and pathologic stage I patients at 0.91 with the 95%CI from 0.85 to 0.98. Conclusion VATS lobectomy is safe and effective. This research shows that domestic technologies of VATS lobectomy and its midterm results have reached the international standard.
