| Objective: To explore the causes and countermeasures of reoperation of differentiated thyroid cancer.Materials and methods: Retrospective analysis of the First Affiliated Hospital of China Medical University from January 2011 to December 2015 admitted to the 252 cases of DTC reoperation clinical data,summarize the cause of reoperation and propose countermeasures.Results: This group of reoperation for 5 reasons: lateral cervical lymph node metastasis,delayed diagnosis and radical recuperation,residual gland recurrence,lymph node metastasis in central area and preoperative misdiagnosis before operation.There were 91cases(36.11%)of cervical lymph node metastases,38 cases(41.76%)of those with less than 1 year of reoperation.Delayed diagnosis and replacement therapy were performed in58 cases(23.02%).The rate of residual cancer in the gland was 25.86% and the rate of lymph node metastasis was 36.21%.Recurrence of residual gland cancer,a total of 54cases(21.43%),of which the first operation was less than the glandular leaf area in 22 cases,accounting for 40.74%.Central lymph node metastasis in 27 cases(10.71%),thefirst operation has been central clearing area 26 cases,accounting for 96.30%.There were 22 cases(8.73%)of clinical misdiagnosis before operation,13 cases were diagnosed due to suspicious lymph nodes,and no puncture pathology was observed before operation.Conclusion: Careful assessment before surgery and the normative surgical treatment is the key to reducing the re-operation rate of DTC. |
