[Treatment of super obesity by laparoscopic Roux-en-Y gastric bypass: experience of 42 cases].

Objective: To investigate the feasibility and efficacy of laparoscopic Roux-en-Y gastric bypass(LRYGB) for super obesity(BMI≥50 kg/m(2)).

Method: Clinical data of 42 patients undergoing LRYGB in the First Affiliated Hospital of Jinan University between 2004 and 2008 were analyzed retrospectively.

Results: All the LRYGB procedures were successfully performed with no conversion to open surgery.

[Antecolic versus retrocolic gastroenteric anastomosis for laparoscopic Roux-en-Y gastric bypass: a prospective randomized control trial].

Objective: To compare short-term postoperative outcomes between antecolic and retrocolic laparoscopic Roux-en-Y gastric bypass(LRYGB).

Methods: 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.

[Treatment of obesity and type 2 diabetes mellitus by laparoscopic Roux-en-Y gastric bypass].

Objective: To investigate the efficacy of laparoscopic Roux-en-Y gastric bypass (LRYGB) in the treatment for obesity and type 2 diabetes mellitus (DM).

Methods: Twenty-one cases of obesity and 9 cases of type 2 DM received the LRYGB. Weigh changes, excess body weight lose rate (EWL%) and blood glucose level were measured after surgery and occurrence of complications was observed postoperatively.

[Laparoscopic Roux-en-Y gastric bypass surgery for treatment of type 2 diabetes mellitus].

Objective: To investigate the surgical approach, feasibility and effectiveness of laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery for treating type 2 diabetes mellitus.

Methods: Seven obese patients with type 2 diabetes and 5 type 2 diabetic patients without obesity received LRYGB surgery. The changes of the body mass, fasting blood glucose (FBG), 2-hour postprandial blood glucose (2 h PBG), C peptide (C-P) and HbA1c% were observed postoperatively.

[Endoscopic thyroidectomy via the areola of breast approach].

Objective: To investigate the feasibility and safety of endoscopic thyroidectomy via the areola of breast approach.

Methods: 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.

[Endoscopic thyroidectomy via chest and breasts approach in 500 cases].

Objective: To discuss the method, the safety, the advantages and disadvantages of endoscopic thyroidectomy via chest and breasts.

Methods: From Mar. 2002 to Dec.

[Treatment for severe rectal prolapse by laparoscopic rectopexy].

Objective: To evaluate the clinical practice of laparoscopic rectopexy in the treatment of severe rectal prolapse.

Methods: From March 1998 to February 2007, 4 cases of complete rectal prolapse, including 1 male and 3 female,ranged 21-82 years old, were treated by laparoscopic rectopexy. In one case, the posterior wall of rectum was freed and elevated, and pre-rectal introcession was closed by silk suture, then the posterior wall was suspended and fixed on sacral promontory fascia, finally the sigmoid colon was fixed by sutures on the fascia of left psoas major.

[Endoscopic thyroidectomy with 150 cases].

Objective: To discuss the method, the advantages and disadvantages of endoscopic thyroidectomy.

Methods: 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.

Results: 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.

Laparoscopic vertical banded gastroplasty for morbid obesity.

Objective: To evaluate the clinical application of laparoscopic vertical banded gastroplasty (LVBG) for morbid obesity.

Methods: Four patients undergoing LVBG were evaluated by comparison of the preoperative and postoperative morbidities and body weights.

Results: Laparoscopic surgery was successfully performed in all the 4 cases without laparotomy.
