RESUMEN
Acute gangrenous cholecystitis is a histologic diagnosis,mostly diagnosed by intraoperative or postoperative pathology.In China,as the aging population increases,the incidence of the disease increases steadily.AGC is still an indication of surgical treatment for acute cholecystitis(AC),but the diagnosis and treatment of AGC remains a challenge for clinical surgeons.However,preoperative clinical data such as age, gender,hypertension,diabetes,coronary heart disease,cholelithiasis disease history,laboratory examination and radiographic results are helpful in early diagnosis and reasonable surgical timing selection.

RESUMEN
Objective To investigate a method to detect the sentinel lymph nodes(SN) of thyroid papillary carcinoma and its predictive value for cervical metastasis of carcinoma. Methods Intraoperative methylene blue dye mapping was performed in 24 cases of thyroid papillary carcinoma. The coincidence rate of frozen section pathology and routine section pathology of SN was observed,and the predictive value of SN for (metastasis) of the cervical lymph nodes was noted. Results SN was successfully detected in 21(87.5%) of 24 cases. The average number of SN was 3 nodes. There was one false negative case, the false negative rate was 4.8%(1/24), and no false positive cases were found. The predictive value of sentinel lymph nodes to (cervical) lymph node metastasis was 83.3%.Conclusions Methylene blue staining to identify sentinel lymph nodes could accurately predict the status of cervical lymph node metastasis of thyroid papillary carcinoma.
