Exposing the recurrent laryngeal nerve (RLN) during all types of thyroid surgery is essential to protect this nerve. Endoscopic thyroidectomy (ET) has gained acceptance from both patients and physicians, in part due to the cosmetic benefits. Therefore, the avoidance of intraoperative RLN impairment during ET is of critical significance. We have developed a standard approach to expose the RLN during ET that prevents RNL impairment.ET was performed in 120 consecutive patients with thyroid disease. In order to develop a standard procedure that protects the RLN, several steps that differed from the traditional open procedure were introduced. First, the thyroid gland was freed from the isthmus instead of the superior pole. Then, the inferior pole of the thyroid gland was meticulously freed, and the lateral side of the thyroid gland was freed followed by the superior pole. At this point, the RLN was easily visualized in the tracheoesophageal groove. The thyroidectomy was then performed simultaneously with exposure of the RLN from the inferior to superior aspects. All RLNs were exposed when hemithyroidectomies, subtotal thyroidectomies, or total thyroidectomies were performed. The operative time and parathyroid hormone (PTH) and calcium levels were recorded prospectively and analyzed.Using this method, all RLNs were easily exposed within 15 minutes. Only one case of transient RLN palsy occurred due to accidental contact of the harmonic scalpel to the nerve. Postoperative hypocalcemia occurred in 23 cases (19.2%), and the PTH level decreased significantly in 33 cases (27.5%). The PTH levels returned to normal within 3 months.Use of the described approach to expose and protect the RLN when performing ET is safe and feasible.

To investigate the feasibility and efficacy of laparoscopic Roux-en-Y gastric bypass(LRYGB) for super obesity(BMI≥50 kg/m(2)).Clinical data of 42 patients undergoing LRYGB in the First Affiliated Hospital of Jinan University between 2004 and 2008 were analyzed retrospectively.All the LRYGB procedures were successfully performed with no conversion to open surgery. Average operation time was 145.1 minutes, volume of blood loss during the surgery was 25.0 ml, and length of postoperative hospital stay was 9.9 days. The cases were followed up for 1 month to 30 months. Body weight and BMI decreased significantly 1 month after the operation and reached a minimum level after 2 years then became stable while excess body weight loss rate(EWL) increased(P0.05). All the obese-related symptoms were relieved significantly. Four cases(9.5%) showed complications during perioperative period including 1 case of respiratory failure, 2 cases of gastrojejunal anastomotic bleeding, 1 case of umbilical wound infection, and 11 developed long-term complications. All of them were cured by conservative treatment.Treatment of super obesity by LRYGB is feasible with significant short-term results. But due to the difficulty of the operation and postoperative complications, comprehensive treatment from experienced bariatric surgical team is needed. The long-term outcome needs for further observation.

To compare short-term postoperative outcomes between antecolic and retrocolic laparoscopic Roux-en-Y gastric bypass(LRYGB).Forty obesity patients were admitted into The First Affiliated Hospital of Jinan University from March 2008 to July 2010. All patients were randomly assigned to undergo antecolic (group A, 20 cases) and retrocolic (group B, 20 cases) gastroenteric anastomosis. Short-term outcomes were compared.LRYGB procedures were successfully performed in all the 40 patients. There were no significant differences between the two groups in estimated blood loss during surgery, time to flatus passage, time to resumption of oral intake, or length of postoperative hospital stay. The operation time was longer in group B than that in group A [(163.4±28.1) min vs.(131.8±22.7) min, P0.05]. There were no patients developed internal hernia or anastomotic leakage in either group. Comparison of short-term gastrointestinal symptoms after surgery showed no statistical significance.Although retrocolic procedure may be closer to anatomical structure, antecolic and retrocolic anastomosis have comparable short-term outcomes after surgery. Further study is warranted to investigate long-term outcomes.

To investigate the feasibility and safety of endoscopic thyroidectomy via the areola of breast approach.Between April 2005 to September 2008, endoscopic thyroidectomy via the areola of breast approach was performed in 28 female patients. Of the patients, 25 cases presented with nodular goiter, 2 cases with Grave's disease and 1 case with minimum papillary carcinoma. The average age was 22.5 years (range, 18-38 years). A 10 mm trocar was placed on the medial border of the areola of the right breast for the video-endoscopy and removing specimens, and a 5 mm trocar was placed on the lateral border of the areola of the same breast as the assisted operation hole. Another 5 mm trocar was placed on the medial border of the areola of left breast as the main operation hole. The operation data was recorded and analyzed.All the 28 operations were successful. The procedures included one lobe total thyroidectomy in 5 cases, one lobe subtotal thyroidectomy in 15 cases, subtotal thyroidectomy in 3 cases, one lobe near total thyroidectomy + the other lobe subtotal thyroidectomy in 4 cases, and one lobe total thyroidectomy + the central group lymph node resection + the other lobe subtotal thyroidectomy in 1 case. The average operation time was 60.7 minutes (range, 40-125 minutes), the average operation blood loss was 5.8 ml (range, 2-15 ml), the average length of post-operative hospital stay was 3.1 days (range, 2-5 days). No adverse effects was found after the operation, such as damage to the parathyroid gland and the laryngeal nerve. The patients were followed-up for 1 to 40 months with satisfactory results. All 28 patients were satisfied with the cosmetic effects of the operation.Endoscopic thyroidectomy via the areola of breast approach produces an outstanding cosmetic effect, it is safe and feasible.

To discuss the method, the safety, the advantages and disadvantages of endoscopic thyroidectomy via chest and breasts.From Mar. 2002 to Dec. 2006, endoscopic thyroidectomy via anterior chest and breast approach was performed in 500 patients, including 76 cases of Grave's disease (1 case had an opened operation history), 111 cases of thyroid adenoma, 291 cases of nodular goiter (10 cases have 1-2 opened thyroidectomy history, 2 cases secondary of hyperthyroidism), and 22 cases of thyroid carcinoma.The endoscopic thyroidectomy was successfully carried out in 492 cases, including tumor enucleation in 50 cases, partial lobectomy in 210 cases, subtotal thyroidectomy in 212 cases (including 73 cases of Graves' disease), and lobectomy in 16 cases of thyroid carcinoma. The operative time length ranged from 40 to 270 min (mean 74.5 min). Mean operative blood loss was 5.5 ml (3-250 ml), no cases underwent blood transfusion. The drainage was taken out in the second or third days postoperatively. Postoperative hospital stay ranged from 3 to 8 days (mean 4.2 days). There were some complications including subcutaneous bleeding (3 cases), burn of the epidermal (1 case), inflammation of the incision (2 cases), subcutaneous bruising (3 cases), subcutaneous effusion (6 cases), thyroid crisis (1 case), and temporarily hoarseness of 2 cases. There were no complications such as permanence damage to recurrent laryngeal nerve or parathyroid glands. The complication rate was 3.6% (18/492). The hospital charges ranged from 7600 to 13,500 RM yuan. The average cost of endoscopic thyroidectomy was 10,510 RM yuan, in contrast to 5700 RM yuan for the open thyroidectomy patients. The post-operative following-up was 3 to 57 months (mean 27 months). All the patients were satisfied with the cosmetic results and the same curative effects as conventional surgery were obtained. However, 3 cases of nodular goiter, 1 case of thyroid carcinoma, and 1 case of Grave's disease were recurrence. The operations were converted into open surgery in 8 cases. The 22 cases with carcinoma were survival until now.Endoscopic thyroidectomy is a safe and effective method of thyroid surgery. Since all the minimal incisions are on concealed parts of the body, the obvious cosmetic effect of this method is guaranteed. Some disadvantages such as complications and more costs are needed to be improve.

To discuss the method, the advantages and disadvantages of endoscopic thyroidectomy.Endoscopic thyroidectomy via areola of breasts approach was performed in 150 patients, including 41 cases of thyroid adenoma, 64 cases of nodular goiter, 40 cases of Graves' disease, and 5 cases of thyroid carcinoma.The endoscopic thyroidectomy was successfully carried out in 144 cases, including tumor dissection in 32 cases, one lobe partial thyroidectomy in 54 cases, two lobe partial thyroidectomy in 19 cases, subtotal thyroidectomy in 37 cases of Graves' disease, and radical thyroidectomy in 2 cases of thyroid carcinoma. The operative time length ranged from 50 to 270 min (mean 80 min). There were no complications such as damage to recurrent laryngeal nerve or parathyroid glands. Postoperative hospital stay ranged from 3 to 7 days (mean 4 days). The post-operative following-up for 1 approximately 13 months indicated that all the patients were satisfied with the cosmetic results and the same curative effects as conventional surgery were obtained. However, the operations were converted into open surgery in 6 cases.Endoscopic thyroidectomy is a safe and effective method of thyroid surgery. Since all the minimal incisions are on concealed parts of the body, the obvious cosmetic effect of this method is guaranteed.

AIM: To analyze the prognostic factors of 5-year survival and 10-year survival in hepatocellular carcinoma (HCC) patients, and to explore the reasons for long-term survival and provide choice of treatment modalities for HCC patients. METHODS: From January 1990 to October 2012, 8450 HCC patients were included in a prospective database compiled by the Information Center after hospital admission. Long-term surviving patients were included in a 10-year survival group (520 patients) and a 5-year survival group (1516 patients) for analysis.The long-term survival of HCC patients was defined as the survival of 5 years or longer. Clinical and biologic variables were assessed using univariate and multivariate analyses. The survival of patients was evaluated by follow-up data. RESULTS: The long-term survival of HCC patients was associated with the number of lesions, liver cirrhosis and Child-Pugh classification. It was not found to be associated with tumor diameter, histological stage, and pretreatment level of serum α-fetoprotein. The differences in clinical factors between the 5-year survival and the 10-year survival were found to be the number of lesions, liver cirrhosis, Child-Pugh classification, and time elapsed until first recurrence or metastasis. The survival period of different treatment modalities in the patients who survived for 5 years and 10 years showed significant differences: (in order of significance) surgery alone > surgery-transcatheter arterial chemoembolization (TACE) > TACE-radiofrequency ablation (RFA) > TACE alone > surgery-TACE-RFA. The 10-year survival of HCC patients was not associated with the choice of treatment modality. CONCLUSION: This retrospective study elucidated survival outcomes, prognostic factors affecting survival and treatment modalities in HCC patients.
