[Objective] Summary of Ming and Qing Dynasties and traditional Chinese medicine before tumor disease, to clarify the concept and to separate the tumor, and the tumor gall. [Method] Carefully read the documents of ancient Chinese medicine literature, combined with the relevant theoretical research methods of TCM, analyze the etiology and pathogenesis of neoplasia and its diagnosis and treatment system, summarize the theoretical system of the disease. [Results] The tumor is between blood stasis and phlegm stagnation. In time, the flesh skin membrane, between flesh and skin, because of its clinical and gall disease shows the organism body mass, so the ancient medical books of the two are collectively referred to as the gall disease. It is equivalent to the surface soft tissue tumor of modern medicine. [Conclusion] Before and after Ming and Qing Dynasties, Chinese medicine has formed a complete system of diagnosis and treatment of tumor, which has a good guiding effect on modern clinic.

Objective To investigate the safety and feasibility of lapraroscopic Heller myotomy combined with Dor fundoplication surgery. Methods Three cases with achalasia have been treated with laproroscopic Heller-Dor surgery since February, 2005. Before surgery, patients were examined for generally esophageal barium meal and esophageal manometry. Results The operation time ranged from 110 and 120 minutes with the bleeding volumes between 40 to 50 ml, and the hospitalized time for patients post operation was 6 to 7 days. During a month after surgery, the patients showed the normal lower esophageal sphincter pressure and remnant pressure, increased the rate of relaxation,disappeared reversed peristalsis and gastroesophageal reflux, and no recurred symptoms. Conclusions In comparison to conventional surgery, Heller-Dor procedure results in smaller wound, less pain, fewer complications, faster recovery, shorter hospitalized days, and better therapeutic effectiveness. The Heller-Dor procedure is safe and feasible.

Objective To discuss the clinical application of lapraroscopic subtotal cholecystectomy in the acute cholecystitis with severe inflammatory and fibrous adhesions at calot triangle.Methods Retrospective analysis of the clinical data,surgical approaches,and short term and long term complications of 74 cases of acute cholecystitis in the period from January 2002 to September2005 in our hospital.Results In the 74 cases operated by subtotal cholecystectomy using laparoscopy,during laparoscopic procedure,71(95.9%) operations were successful;a case of Mirizzi syndrome could not be confirmed to have the residual stones in cystic duct and another case of the same syndrome was not confirmed to have the duodenum fistula.These two cases were then dealt with by conventional surgery and constituted 2.7% of the total cases.One case was dealtd with by second surgery because of the residual stones of cystic duct after lapraroscopic subtotal cholecystectomy and constituted 1.3% of the total cases.One case was found with minor bile leakage and constituted 1.3% of the total cases.Cholangiography was conducted 41 cases during operation,of whom,39 cases were normal and 2 cases failed.No death occurred with the operation of the lapraroscopic subtotal cholecystectomy.Conclusion It is safe and effective to apply laparoscopic subtotal cholecystectomy to treat acute cholecystitis with severe inflammatory and fibrous adhesions at calot triangle.

Objective To evaluate the safety and efficacy of laparoscopic splenectomy plus esophagogastric devascularization for the treatment of portal hypertensive variceal bleeding and secondary hypersplenism. Methods Laparoscopic splenectomy and devascularization of the lower esophagus and upper stomach were performed in ten cirrhotic patients between January 2000 and July 2005. Esophageal transection and reanastomosis performed by a stapler at the lower end of the esophagus was added to two patients through a small accessory incision. Results The procedure was successful in all cases without conversion to open surgery. The operation time ranged from 4.5 to 5.5 hours and the blood loss was 100 ~ 400 ml. The postoperative hospital stay was 8-15 days. Conclusion Laparoscopic splenectomy and portaazygous disconnection is a feasible, effective and safe procedure as well as minimally invasive hence is applicable for patients with portal hypertension and hypersplenism.

Objective To explore the short-term result and safety of laparoscopie sleeve gastrectomy and partial enterectomy for the treatment of morbid obesity.Methods Ten patients underwent laparoscopic sleeve gastrectomy,omentectomy,and partial enterectomy as a treatment option for weight reduction between December 2006 and September 2007.The procedure included 70%-75%vertical (sleeve)gastrectomy,omentectomy,and 1/3 to 2/5 enterectomy preserving proximal jejunum and most of the ileum. Results Laparoscopy was completed in all patients,no conversion to open surgery.The operation time averaged at 3.1 hours(range 2.5-3.5 hours),and there was no postoperative complications.The median postoperative hospital stay was 7 days(range 6-8 days).Mean preoperative BMI was 36.1(32.0-40.5)kg/m2.Mean decrease in BMI was 4.1(3.0-4.7)ks/m2,5.6(3.2-9.0)kg/m2,and 7.3(3.2-10.7)kg/m2 respectively,and mean weight loss at postoperative 1,3,and 6 months was 11.7(7-15)kg,17.5(8-25)kg,and 22.0(8-32)kg respectively.Conclusion Laparoscopic sleeve gastrectomy with omentectomy and partial enterectomy is an effective and safe surgical option for the treatment of morbid obesity.

ObjectiveTo explore efficacy and safety of laparoscopic sleeve gastrectomy for the treatment of obesity.MethodsForty patients underwent laparoscopic sleeve gastrectomy as a treatment option for weight reduction between December 2006 and February 2010.Mean preoperative body weight (BW),body mass index (BMI) and exceed body weight (EBW) were(104.2 ±3.3) kg,(36.9 ± 1.0) kg/m2 and (37.8 ±3.0) kg,respectively.Outcome data were collected and assessed prospectively.ResultsLaparoscopic procedures were completed in all patients,with no conversion to open surgery.The operation time averaged (80 ± 18 ) min,and there were no severe postoperative complications.The median postoperative hospital stay was (5.5 ± 1.5 ) days.BMI loss was (4.3 ± 1.7 ) kg/m2,( 7.0 ± 1.9 ) kg/m2,(9.3 ±3.1) kg/m2 and (10.1 ±3.8) kg/m2,respectively,and percentage of EBW loss was 35.0％ ± 13.5％,57.1％ ± 17.7％,74.2％ ±27.2％,and 81.8％ ±29.4％,respectively,at 1,3,6,and 12 months following the procedure.ConclusionLaparoscopic sleeve gastrectomy is an effective and safe surgical option for the treatment of obesity with lower BMI.Additional long-term studies are still needed to accurately compare laparoscopic sleeve gastrectomy with other procedures of weight reduction.

Objective To investigate the technical requirements for the 3.0T multi-modal quantitative MR imaging of the rabbit liver.Methods A total of 8 rabbits were scanned and T1 mapping,T2 mapping,MT and Gd EOB-DTPA dynamic enhancement images were acquired.For the dynamic enhanced scanning,injecting contrast medium was followed by saline flush with different combinations of injection flow rate (1.5 mL/s and 2 mL/s) and injection volume(6 mL and 8 mL).The quality of the images was assessed and analyzed statistically.Results The total scanning time was about 20-25 min.High-quality images were acquired by T1 mapping,T2 mapping and MT sequences.There was no significant difference in image quality among different groups in Gd-EOB-DTPA dynamic enhanced scanning(P＞0.05).Two rabbits died when the combination of injection flow rate of 2 mL/s and injection volume of 8 mL was used.Conclusion 3.0 T multi-modal quantitative MR scanning of rabbit liver can be achieved successfully if scanning parameters are properly chosen.
