ABSTRACT
[ABSTRACT]OBJECTIVETo study the expressions of 34βE12, Galectin-3 and HBME-1 in thyroid nodules, and to explore its diagnostic value for papillary thyroid carcinoma (PTC).METHODSEn VisionTM immunohistochemical technique was used to detect the expression of 34βE12, Galectin-3 and HBME-1 in 352 thyroid lesions. The correlation between the expressions of the 3 protein markers and clinicopathological characteristics was evaluated. The receiver operating characteristic area under the curve (ROC-AUC) and their index for diagnosis evaluation were also calculated.RESULTSThe positive rates of 34βE12, Galectin-3 and HBME-1 in 246 PTC lesions were significantly higher than those in benign nodules (P<0.001). There was no relationship between the expression of the 3 protein markers and clinicopathological characteristics (eg. gender, age, numbers of lesions, tumor size, capsular invasion, lymph node metastasis, TNM staging). The ROC-AUC of 34βE12, Galectin-3 and HBME-1 for diagnosis of PTC was 0.936, 0.915 and 0.898 respectively. The sensitivity of 34βE12, Galectin-3 and HBME-1 for diagnosis of PTC was 94.3%, 95.5% and 91.1% respectively, while the specificity was 81.1%, 71.7% and 83.0% respectively, and the diagnostic accuracy rate was 90.3%, 88.4% and 88.6% respectively.CONCLUSION The expressions of 34βE12, Galectin-3 and HBME-1 are statistically different between PTC and benign lesions, but no associations are found with clinicopathological characteristics, indicating the three protein markers have important diagnostic value for PTC.
ABSTRACT
Objective To evaluate the TriVex system in the treatment of varicose veins of lower extremities,focusing on postoperative complications and management.Methods Clinical data of 108 patients (146 legs) of varicose veins of the lower extremity undergoing TriVex procedure were retrospectively analyzed.Deep veinons patency was verified in all patients by preoperative sonography.Above knee stripping of the great saphenous vein was done first when necessary.The below knee phlebectomy of the side branches was done with the new system (Trivex System/Smith and Nephew).Postoperative patients were followed-up,and results were evaluated.Results Procedure was successful in all cases.98 cases were followed up for 1 ～ 24 months.The mean operation time per leg was (34±8) minutes.Complications were as following:26 legs (17.8%) developed postoperative hematoma which was healed by conservative therapy including two cases in which the tension seroma,which was successfully managed by puncture aspiration.Transien skin numbness or paraesthesia developed in 13.0% (19/146).Subcutaneous induration in 11.6%(17/146) cases.Residual varicose and recurrence in 3.4% (5/146).Incision related complications developed in 4.8% (7/149) cases.Conclusion Transilluminated powered phlebectomy (TriVex) is a safe and effective cosmetic procedure for less invasive varicose vein surgery.
ABSTRACT
Objective To discuss the diagnosis and surgical management of acute gangrenous cholecystitis (AGC) early after EST and ERCP. Methods Clinical and pathological data of 1468 cases receiving EST and ERCP in our hospital from 2005 to 2007 were retrospectively analyzed. Results AGC occurredin 16 cases and the incidence was 1.09%. Its main manifestations were pain in the right upper abdomen with local pertonitis and fever 1 to 3 d after operation, blood WBC exceeding 15.0× 109/L in 15 cases (93.8%), gallbladder tumefaction and double layer structure by B mode ultrasound, the diagnostic accuracy before operations was 81.3 %. We performed cholecystectomy in 10 cases, cholecystectomy and choledochotomy for common bile duct exploration and stone removal and T-tube drainage in 2, partial cholecystectomy in 3, cholecystostomy in 1. Pathological examination showedthat it was AGC in all the patients. Conclusion Latency in 1 to 3 d, local pertonitis, high blood WBC and B mode ultrasound are main managements in diagnosis of AGC and it should be diagnosed carefully distinguished from perforation and severe acute pencreatitis. It is suggested to undergoing early surgi-cal management once diagnosed definitely.
ABSTRACT
Objective To analyze incidence of thyroid carcinoma and to explore and conclude the principle of its diagnosis and treatment.Methods One hundred and forty six patients of thyroid carcinoma in our hospital were analyzed and discussed with literature.Results 101 cases were diagnosed as thyroid carcinoma by pathological diagnosis of fast frozen sections,the positive ratio is approximately 93.5%.totle resection of affected lobe and isthmus was performed on 35 cases,total resection of affected lobe and isthmus and majority of opposite lobe was done on 37 cases.The lymph node metastasis was found by postoperative pathological diagnosis with a rate of 32.5%.Conclusions Preoperative diagnose of thyroid carcinoma is rarely available,diagnosis of thyroid carcinoma by fast frozen sections is optimal.total resection of affected lobe and isthmus or total resection of affected lobe and isthmus and majority of opposite lobe are the main operation patterns.
ABSTRACT
Objective To investigate the causes and measurement of the colonic fistulas after severe acute pancreatitis(SAP),so as to increase its cure rate.Method A retrospective study was made on 19 SAP cases complicated with colonic fistulas after drainage operation in order to find out the risk factors,the location and the time of complicated colonic fistulas,and to sum up the experiences of earlier diagnosis and comprehensive treatment.Results Most patients occurred colonic fistulas within 4~6 weeks postoperation.Seventeen patients recovered,the cure rate being 89.5%(17/19),and two case died of serious systemtic infection and multiple organ systemtic failure.Conclusions Colonic fistulas complicated by SAP is related to anatomic factors,the degree of local inflammation,the way of draingic tube putted away,and improper surgical therapy.Comprehensive therapy including taking double cannula to drainage in active,earlier jejunostomy nutrition support or colostomy,supplementing with recombinant human growth hormone can lead to better results.
ABSTRACT
Objective To sum up the therapeutic experience for pancreatic abscess complicated with severe acute pancretitis (SAP) and to compared the methods of drainage according to its classification , so as to guide the clinical work. Methods Altogether clinical datas of 58 patients with pancreatic abscess were collected in the latest 20 years, pancreatic abscess were divided into 3 groupes according to its size,locationa and figure.Four methods of drainage including open operation drainaging,percutaneous puncture drainaging, small incision drainaging at lower location but not into peritoneal cavity and “F” tube drainaging were adopted.Results 29 cases drainaged by open operation ,among them 10 adopted second look operation and 4 cases third look operation 5 died of the severious complications such as overwelming blooding and intestinal fistula;10 cases through percutaneous puncture drainage ,6 cases cured and the rest converting to open operation and then cured ; 12 cases by small incision through lower location but not into peritoneal cavity ,all cured.Conclusions The results sugggest the effects of drainge related directly to the choose of methods of drainage for pancreatic abscess complicated with SAP,pancreatic classification and to choose an appropriate way according the aforementioned standard will benefit clincial work.
