Purpose: Prophylactic central compartment node dissection is gaining acceptance in the treatment of papillary thyroid carcinoma (PTC). However, its benefits remain controversial. The aim of study was to evaluate the effects of prophylactic central compartment node dissection on the complication rate and the short-term disease-free survival rate.Methods: Our treatment strategy for PTC without clinical evidence of lymph node metastasis has been changed from total thyroidectomy alone (group I) to total thyroidectomy with prophylactic central compartment node dissection (group II) since January 2007. Before and after 2007, 70 consecutive patients were selected in each group. Results: The average age of patients was 46.3±11.8 years. Average follow-up period was 51.9±10.9 months. The average size of maximum diameters of the tumors was 1.3±0.8 cm. Lymph node metastasis was identified in 22.9% of patients in group II. Recurrent laryngeal nerve injury occurred in one patient in each group. Temporary and permanent hypoparathyroidism occurred in 32.9% and 2.9% in group I, 40.0% and 7.1% in group II respectively (P=0.483 and P=0.441, respectively). Locoregional recurrences developed in seven patients in group I. Fifty month disease-free survival rate was 90.0% and 100% in group I and group II, respectively (P=0.0078). Conclusion: Prophylactic central compartment node dissection did not seem to increase the risk of recurrent laryngeal nerve injury, but may increase the risk of temporary and permanent hypoparathyroidism. Prophylactic central compartment node dissection decreased the risk of locoregional recurrences, especially in central compartment. However, the size of metastatic lymph nodes in central compartment in the present study was relatively small and their clinical implication remains to be evaluated.

Purpose: This clinical research was performed to determine the safety of laparoscopic appendectomy using a 5 mm scope by comparing the outcomes with open appendectomy. Methods: We examined the medical records of 441 patients that underwent either laparoscopic appendectomy (LA) or open appendectomy (OA) from March 2005 to August 2007. We retrospectively reviewed the clinical data and compared: age, gender, days of hospitalization, operation time, time to oraldiet, complications, and readmission, between the LA and OA groups. Results: Among the 441 patients that were diagnosed with appendicitis, LA was attempted in 332 patients; 325 (73.7%) of them received the procedure. One hundred-nine patients (24.7%) received an OA. There were no differences in operation time (p=0.072), length of hospitalization, and complication or re-admission rates; however the time to oral diet (p=0.025) was earlier in patients in the LA group. There were no differences in the outcomes of patients that had an uncomplicated appendicitis and received LA or OA; however patients diagnosed with complicated appendicitis had a shorter length of hospitalization after a LA compared to those that had an OA (p=0.03). Conclusion: There was no difference in safety between the laparoscopic appendectomy using a 5 mm scope and an open appendectomy. Laparoscopic appendectomy using a 5 mm scope provided a better cosmetic outcome.
