Ojective To investigate the value of preoperative B-type ultrasonicd examination in the choice of incision of minicholecystectomy. Methods Before performing minicholecystectomy the size of gallbladder and the thickness of abdominal wall measured by B-type ultrasonography the projections postion of gallbladder bottom and neck on abdominal wall were marked in 95 patlents. Results The incision of 82 cases were determined by the linea formed with linking the projection of gallbladder bottom to neck on abdominal wall. The procedure with two aperture was chosen in 11 cases and the incision was extended in 2 cases out of them. The operation visual field was clear and common bile duct and hepatic artery and port vein could be differentiated. The incidenec of complications was 5.3%(5/95) and no severe complication occurred. Conclusions Preoperative B-type ultrasonogrophy is a simple and effective method for the choice of incision of minicholecystectomy in the term of individuation

Objective To investigate the best pathologically diagnostic method for breast cancer before surgery. Methods Wet fine needle aspiration cytology was conducted in 68 cases of probable breast cancer by using a 10 ml syringe with size 7 needle. Results Malignant cells were found in 19 cases,without any false positive cases.Of the remaining 49 cases of negative cytological findings: 46 cases underwent segmental mastectomy,1 of which was postoperatively diagnosed as having fibrosarcoma by paraffin section examination and the rest of which were all demonstrated the presence of benign tumors;3 cases without surgical intervention were followed for (11～20) months and no evidences of breast cancer were found.The sensitivity was 95 0% (19/20),the specificity was 100% (48/48),the accuracy rate was 98 5% (67/68),and the false negative rate and false positive rate were 5 0% (1/20) and 0 (0/48),respectively.Of the 19 cases of positive cytological findings,no implantation metastasis in needle passage occurred.There were no complications in the study. Conclusions Wet fine needle aspiration cytology is safe,economical,convenient,quick,almost painless,and accurate,being the method of first choice in the diagnosis of breast cancer.
