【Abstract】Objective To assess the value of 99Tcm-tetrofosmin imaging in discriminating malignant mass from benign breast mass.Methods From June 2000 to January 2002, 104 patients with breast mass detected by clinical examination were included. After 740 MBq 99Tcm-tetrofosmin was injected intravenously in the contralateral arm to the breast lesion, the front and the lateral images were collected in 5 min, 10 min and 20 min respectively. 99Tcm-tetrofosmin imaging localized in breast was defined as the positive sign of affinitive tumor. All patients underwent operation within one week. Using histological assessment as a golden standard, the sensitivity, specificity, positive and negative predictive value for 99Tcm-tetrofosmin SPECT of the breast were calculated respectively. Results The sensitivity of 99Tcm-tetrofosmin imaging for discriminating between malignant mass and benign mass in palpable breast lesions was 87%, specificity 84%, positive and negative predictive value were 85% and 86% respectively. Conclusion The results suggested that 99Tcm-tetrofosmin imaging is a valuable tool for distinguishing between malignant mass and benign mass in palpable breast lesions.
ObjectiveTo investigate the diagnostic value of endoscopic retrograde cholangiopancreatography (ERCP) in obstructive jaundice of elderly patients. MethodsTotally 338 patients with obstructive jaundice underwent ERCP were divided into elderly group (age ≥60 years old) and nonelderly group (age lt;60 years old) based on age. The levels of serum amylase (AMY), ALT, and TBIL in 6, 24, and 48 h after ERCP were detected. The success rate of cholangiopancreatography, accuracy rate of diagnosis, and incidence of complications after ERCP in two groups were analyzed. ResultsThe difference of serum AMY, ALT, and TBIL levels of patients in 6, 24, and 48 h after ERCP were not significant between two groups (Pgt;0.05). The success rate of cholangiopancreatography in nonelderly group was 96.3% (130/135) and in elderly group was 96.1% (195/203), and no difference was found (Pgt;0.05). However, the accuracy rate of diagnosis of ERCP in nonelderly group (84.6%, 110/130) was significantly lower than that in elderly group (98.5%, 192/195), Plt;0.05. The difference of the incidence of complications was not significant between two groups 〔14.8% (20/135) vs. 17.2% (35/203)〕, Pgt;0.05. There was no mortality in two groups patients. ConclusionERCP is a safe, effective, and accurate method, which is of importance to the diagnosis of obstructive jaundice in elderly patients.
From 1987 to 1993, 12 cases of primary gastric malignant lymphoma (PGML) were hospitalized. The incidence of PGML was 1.9% of gastric malignancies during the same period. There were 5 cases in stage Ⅰ, 4 in stage Ⅱ, 1 in stage Ⅲ, and 2 in stage Ⅳ. The preoperative diagnosis of PGML was difficult because the incidence of PGML is low, the symptoms are nonspecific, and the radiologic and fibrogastroscopic character were very similar to those of gastric carcinoma and peptic ulcer disease. The surgical treatment of PGML is disccused.
To study the relationship between the level of serum thyrotropin receptor antibody (TRAb) and the severity of Crave′s disease. From August, 1996 to June, 1998, 156 outpatients with Crave′s disease were followed up. The level of serum TRAb were measured by radio-receptor-analysis (RRA). Results: ①The level of serum TRAb rose in 90.1% of the untreated group; ②The level of serum TRAb restored to normal after the antithyroid drugs were used and the thyroxine level in serum returned to normal; ③In recurrent patients with the treatment of131I, drugs or operation, the serum TRAb level increased. Conclusion: The level of serum TRAb has great significance in the diagnosis, treatment and follow up of the Crave′s disease.
Objective To explore the subdivision method of diagnosis-related group (DRG) by case-mix payment, and provide reference for reasonable imbursement mechanism and standard for DRG grouping, as well as disease cost accounting and performance assessment for hospitals. Methods The first page data of medical records of 17010 inpatients with uterine fibroids in Obstetrics and Gynecology Hospital of Fudan University from 2019 to 2021 were included. Based on the disease and treatment, combined with the length of hospital stay, other diagnosis and other factors, nonparametric test and generalized linear model were used to explore the factors affecting hospitalization expenses. Decision tree model was performed to yield case-mix related groups and predict the cost. Results The inpatients with uterine fibroids were classified into 13 groups in decision tree model based on the main surgical methods, other surgical types, and length of hospital stay. The reduction in variance was 0.34, and the coefficient of variation was 0.19-0.88. Conclusions The case-mix payment approach based on the decision tree model as the grouping method is more consistent with the actual clinical diagnosis and treatment of uterine fibroids, and can be used as method reference for the subdivision of DRG. Under the background of DRG, subdivision of DRG can provide decision-making basis for refined hospital management, including in-hospital cost accounting and performance allocation.
Diagnosis and surgical procedures were studied in this paper. Twentyfive cases of insulinoma were treated surgically from 1970 to 1997, in which 10 patients had Whipple′s triad so that the early diagnosis could be made. The sites of tumours were found in 10 out of 12 undergoing. Selective celiac angiongraphy with the accuracy rate of 83%, but B-ultrasonography and CT gave only 10% (4 out of 25) and 40%(8 out of 20) respectively. In this series, 5 cases underwent bodytail pancreatectomy and 20 cases enucleation of insulinoma. Blood glucose levels were tested during operation in 15 cases, and they all reached the normal level one hour after the tumours were completely removed. The authors consider that Whipple′s triad is the main basis in diagnosis of insulinoma. The selective celiac angiongraphy play an important role in detecting and locating the tumour. If diagnosis is made, surgical operation should be taken. The blood glucose monitoring during operation is the hallmark for complete resection of insulinomas.
OBJECTIVE The purpose of this study was to find the best material for valvular wrapping operation of deep vein of lower limb and to study the diagnostic value of colored Ultrasonic-Doppler for valvular incompetency of the deep vein and the function of the popliteal valve. METHODS Strips of autogenous saphenous vein, autogenous fascia lata and pieces of polytetrafluroethylene artificial vessel were used respectively as the wrapping material for narrowing the valve in 30 dogs. The results of three different wrapping material were obtained by colored Ultrasonic-Doppler and transpopliteal venography in 78 patients. The hemokinetics of the popliteal valve was examined in 20 normal persons. RESULTS In the saphenous vein and fascia lata groups, diffuse fibrosis and marked narrowing of the femoral vein were found, while in the group of artificial vein graft, the graft was intact without prominent fibrosis and narrowing of the vein. In comparing with the result of venography, the accuracy of diagnosis by colored Ultrasonic-Doppler was 91.86%. The femoral and popliteal venous valves closed at the same time when holding the breath, but the popliteal venous valve opened more widely than the femoral venous valve when the calf muscles of the leg contracted. CONCLUSION It was suggested that the graft was the best material for valvular wrapping operation, and colored Ultrasonic-Doppler was an important and non-invasive method for the diagnosis of incompetency of deep vein. The popliteal venous valve was the important barrier for protection of the function of deep vein.
Objective To evaluate the markers which contribute to diagnosis and prognosis of thyroid neoplasm. Methods The references about thyroid markers in recent years were reviewed. Results CD26 and galectin-3 could be regarded as a simple, potent markers to differentiate thyroid carcinoma in preoperative diagnosis, CD97 was a specific marker for undifferentiated thyroid carcinoma and its metastasis, CD15 and telomerase could be used in fine-needle aspirate biopsy (FNAB) of thyroid mass, and to improve its diagnostic evaluation, RET/PTC was mainly expressed in thyroid medullary carcinoma, oncofetal fibronectin (oncFN) was specific to papillary and anaplastic carcinoma, thyroid peroxidase was used to identify benign and malignant thyroid tumor. Conclusion Although there are a lot of markers for thyroid neoplasm, but there is no marker which are completely specific to certain histotype of thyroid neoplasm at present.
Objective To analyze the central visual fields and the ocular fundus changes of both eyes of patients with pituitary adenoma.Methods A total of 70 cases of pituitary adenoma received the examination of static central visual fields of all-liminal values by Humphrey instruments 750 cycloscope and the fundus exams by Topcon TRC-50X fundus photography before operations. Results There were 64.3% patients with decreased visual acuities, 80.7% with the defect of visual field, and 46 .4% with fundus changes. The decrease of the visual acuity was the first diagnostic symptom in 45.7% patients, among whom 28.6% were misdiagnosed as ocular diseases.Conclusions The misdiagnosed cause is that the first diagnostic symptom is the decrease of visual acuity without defect of visual field accompanied by ocular diseases. To avoid the misdiagnosis and the omitter of pituitary adenoma, general examination of visual field should be carried out in the patients with decreased visual acuity and optic atrophy with unknown reason in the clinical diagnosis of ophthalmology.

Objective?To summarize our experience of surgical treatment of Boerhaave’s Syndrome. Methods We retrospectively analyzed clinical records of 14 patients with Boerhaave’s syndrome in West China Hospital between January 1998 and December 2011. There were 11 male patients and 3 female patients with a mean age of 55.2±14.4 years and mean time interval between onset and admission of 49.6±21.2 h. Primary repair was performed in 11 patients.Esophagectomy and reconstruction of digestive track was performed in 1 patient and intra-luminal stent implantation was applied in 1 patient. Intercostal catheter insertion was performed in 1 patient.?Results?Thirteen patients underwent surgical therapy, and their survival rate was 84.6% (11/13). Among the eleven patients who underwent primary repair, 8 patients (72.7%)were cured and 3 patients experienced postoperative leakage resulting 2 deaths. The other one patient was cured with in-hospital time of 22.3±7.0 d. Two patients underwent digestive track reconstruction and intra-luminal stent implantation respectively and all survived with in-hospital time 39.0±5.7 d. Another patient underwent bedside chest drainage and died 10 d after admission.?Conclusion?Aggressive surgical management is an effective way to treat Boerhaave’s syndrome, and primary repair can lead to ideal prognosis in delayed patients whose time interval between onset and admission is beyond 24 h. Digestive track reconstruction and intra-luminal stent implantation are alternative methods on condition that primary repair can not be accomplished.
