ABSTRACT
Background@#Suture ligation has been used widely for the treatment of rudimentary type extra digits, but several complications related to this treatment have been reported. The purpose of this study was to describe a new technique for excision of rudimentary preaxial polydactyly of the hand using electrocautery and assess its clinical outcomes. @*Methods@#The authors performed a retrospective study of 34 thumbs (32 patients) that had undergone excision of rudimentary preaxial polydactyly using electrocautery under local anesthesia. The mean follow-up period was 16.5 months. @*Results@#All children had full range of thumb motion without angular deformity at the most recent follow-up. There were no postoperative complications such as bleeding or infection. In 33 thumbs (97.1% of 34 thumbs), there were no signs of residual digit prominence. One thumb had a residual digit prominence at the extra digit removal site. In two thumbs, scar hypertrophy was evident at the operation site. All parents of the patients except two were very satisfied with this technique and the mean visual analog scale score for satisfaction was 9.5 ± 2.0 (range, 0–10). @*Conclusions@#Excision of rudimentary preaxial polydactyly of the hand with the use of electrocautery could remove an extra digit completely in 97.1% of the cases. This technique would be a useful alternative to suture ligation, surgical clip application, or surgical excision for the treatment of rudimentary preaxial polydactyly of the hand.
ABSTRACT
BACKGROUND AND OBJECTIVES: The incidence of thyroid cancer is increasing worldwide. The increase in the frequency of screening tests may have led to an over-detection of small thyroid cancers. The Korean Thyroid Association (KTA) discourages the find needle aspiration of thyroid nodules < or =0.5 cm. The aim of this study was to evaluate time trends of characteristics of thyroid cancer patients in a single medical center. MATERIALS AND METHODS: This study included 15,465 patients who underwent operation due to thyroid cancer from 1995 to 2012. Data on age, gender of patients and histology, clinical stage of the thyroid cancer were reviewed retrospectively. RESULTS: New thyroid cancer cases have dramatically increased and papillary thyroid carcinoma (PTC) accounted for a major part of this increase. PTCs were accounted for 98% of all thyroid cancer surgeries in 2012 and 79% in 1995. The proportion of PTCs < or =0.5 cm has increased from 1% in 1995 to 32% in 2009 and then slightly decreased afterward. The peak age of patients with PTC has increased from 40 years in 1995-2000 to 55 years in 2006-2012. The proportion of small follicular thyroid carcinomas and medullary thyroid carcinomas (< or =1.0 cm) also steadily increased during study periods. CONCLUSION: Thyroid cancers became smaller but, increase of very small PTCs stopped after 2010, in which the KTA guidelines were introduced. These findings suggest that the increasing incidence of thyroid cancer in Korea might be due to the over-detection of small thyroid cancers.
