Objective To evaluate the feasibility and safety of endoscopic thyroidectomy via anterior chest and breast for the treatment of patients with papillary thyroid carcinoma ( PTC ).Methods Endoscopic thyroidectomy was performed in 85 PTC patients between March 2006 and March 2010. Diagnosis was based on intraoprative frozen section. There were 83 females and 2 males, age averaged at 36. 3 years. Sixty three of 85 cases were diagnosed preoperatively as thyroid carcinoma and US revealed ipsilateral cervical lymph node enlargement suspective of metastasis in 12 cases. Endoscopic thyroidectomy plus selective neck dissection was performed. Results This procedure was carried out successfully in 84patients. There were 51 cases of papillary thyroid microcarcinomas(<1. 0 cm) , 28 cases between 1. 0 cm and<2. 0 cm, and 5 cases with the diameter between 2. 0 cm and 3. 0 cm. Total thyroidectomy, ispilateral lebectomy and ispilateral lebectomy plus contralateral subtotal lobetomy were performed in 4, 6, 74 cases,respectively. Central compartment dissection was performed in all of the 84 cases and ipsilateral neck dissection was also performed in 12 cases that were suspected metastatic lateral neck lymph nodes. The mean operative time was (113. 3 ±46. 5) minutes. No significant blood loss occurred. The mean number of lymph nodes yield in the central compartment and lateral compartment were 6. 5 (range 2 to 14) and 19. 2 (range 9 to 26 ), respectively. Forty-four cases ( 44/84, 52. 4% ) had metastatic lymph nodes in central compartment, while 11 cases (11/12,91.1% ) in lateral compartment. Six patients (6/84,7.14%) had transient vocal cord palsy and recovered after 1-2 months. Postoperative transient hypocalcaemia occurred in 4 cases (4. 8% ) , and there were no other major complications. The average postoperative hospital stay was 3. 7 days (range 3 to 6). No evidence of residual or recurrent disease was found at follow-up. The cosmetic results of this procedure were excellent. Conclusions The anterior chest and breast approach of endoscopic thyroidectomy is feasible and safe and cosmetic worthwhile for selected cases of PTC.

OBJECTIVETo summarize the experiences of applying three-dimensional (3D) technique in scarless endoscopic thyroidectomy (SET) via anterior chest approach.
METHODSMedical records of patients who undenvent SET using 3D technique from December 2013 to May 2014 were retrospectively reviewed. A total of 32 patients who had a preoperative ultrasound-guided fine-needle aspiration cytology diagnosis of unilateral papillary thyroid carcinoma and underwent lobectomy associated with central lymph node dissection were included in this study. All patients were female with a mean age of (37 ± 10) years at diagnosis. In addition, 45 female patients who underwent traditional endoscopic thyroidectomy at the same period were randomly selected as control.
RESULTSAll surgical procedures were successfully finished. The mean surgical time in 3D group was (91. 7 ± 11. 4) minutes, and mean hospitalization time was (3. 2 ± 0. 5) days. Contemporary hoarseness was observed in one patient, and no bleeding, infection, hypocalcemia and other postsurgical complications were observed. Compared to the traditional endoscopic surgery group, 3 D group had significantly shorter surgical time of lobectomy ((23. 2 ± 5. 1) minutes vs. (28. 0 ± 5. 0) minutes, t = 4. 156, P = 0. 000). Negative results were seen in the time taking of creating surgical space ((14. 6 ± 3. 3) minutes vs. (15. 6 ± 2. 5) minutes), central lymph node dissection ((25. 1 ± 5. 4) minutes vs. (24. 4 ± 6. 3) minutes) and total surgical time ((91.7 ± 11. 4) minutes vs. (96. 1 ± 13. 0) minutes).
CONCLUSIONApplication of 3D technique in endoscopic surgery can offer 3D vision of the surgical field, thus significantly shorten lobectomy time and more easily to achieve fine dissection and functional protection of recurrent laryngeal nerves, parathyroids and other vital anatomic structures.

Objective To report a randomized trial in comparing the clinical outcomes of three-port LC versus standard four-port LC. Methods From March 2001 to August 2004, four hundred consecutive patients who underwent elective LC were randomized to receive either the three-port or the four-port technique. All patients were blinded to the type of operation they underwent. Postoperative overall pain and incisional pain at different sites were assessed on the first day after surgery using the Prince-Henry scale. Other outcome measures included length and success of the operation, analgesia requirements, postoperative complications, postoperative stay, and the cosmetic results. Results There was no difference between the two groups in age, sex, weight or other diseases. In terms of outcome, patients in the three-port group had less pain at individual subcostal port sites and better cosmetic results. Success rate, mean operative time, complications, subxiphoid port and overall pain score, analgesia requirements, and postoperative hospital stay were similar between these two groups. Conclusion Three-port LC resulted in less individual port-site pain and similar clinical outcomes but fewer surgical scars compared to four-port LC. The three-port technique is as safe as the standard four-port procedure for LC. Thus, it can be recommended as a routine procedure in elective LC.
