RESUMEN
Objective To explore the clinical characteristics,misdiagnosis reason,diagnosis and treatment of primany small intestinal tumor.Methoed Retrospective analysis of the clinical data were made on 40 cases of primary small intestinal tumors.Results Before operation,13 cases were given confirmed diagnosis of small intestinal tumor.The rate of misdiagnosis was 67.5％ (27/40).Partial excision were administered in 10 cases with benign small intestinal tumor.Adical excaision were performed in 24 cases with malignant tumors,palliative excision in 3 cases and shortcut operation in 3 cases.One patient died after opreation.Conclusions Before operation,the misdiagnostic rate of primary small intestinal tumor is high.Fiber endoscopy and X-ray may bring a high diagnostic rate of small intestinal tumor.
RESUMEN
Objective To compare the degrees of stress reaction among laparoscopic cholecystectomy(LC),mini-incision open cholecystectmy(MIOC) and conventional open cholecystectomy(OC).Methods Ninety patients with gallstone were randomly divided into three groups:(LC),(MIOC) and (OC).Blood Thyroxin(T 3),throid-stimulating hormone(TSH),cortisol,insulin,glucose,white blood cell and temperature were measured and/or recorded in the perioperative period.Results The stress rection in LC was significantly lighter than that in OC,but the stress reaction degree in LC and MIOC were basic equality.Conclusion The stress reaction in LC is small than those of OC.
