Objective To evaluate the use of LigaSure vessel sealant system on hemorrhoidectomy for the patients with grade 3 and grade 4 hemorrhoids. Methods Sixty five patients with hemorrhoids (41 males and 24 females), among whom 46 cases were grade 3 and 19 cases were grade 4, underwent hemorrhoidectomy under local anesthesia with the use of LigaSure vessel sealant system. The time consumed for operation and the blood volume lost during and after operation were recorded. Postoperative pain was assessed by means of visual analog score (1-10). The patients were followed up for 2 months. Results The operations were performed successfully in all patients. The time consumed was 5-25 minutes (9.7?4.6 minutes). The pain scores at 4 hours and 24 hours after operation were 1-7 (2.7?1.7) and 0-5 (1.9?1.3), respectively. On the third day after operation, only 4 cases had a pain score of 3 to 5, in the remaining 61 cases the score was under 3. On the seventh day after operation, only 5 patients had pain scores of 1 to 3. No patients complained pain about 2 months later. The volume of blood loss in 9 cases was less than 15ml (15.8%), and in the remaining 56 cases there was no apparent blood loss during the operation. Only one patient was re-operated for bleeding after operation, and in 18 (27.7%) patients there was only oozing of blood. Mild incontinence occurred in 6 patients shortly after operation, and no severe complications occurred. Conclusions LigaSure vessel sealant system shows the advantage of good haemostatic effect, less time consuming for operation, and less pain after operation for the treatment of patients with Grade 3 and Grade 4 hemorrhoids.

Objective To investigate the clinical effects of laparoscopic repair of esophageal hiatal hernia using Bard CruraSoft PTFE/ePTFE Mesh combined with Toupet partial fundoplication.Methods From August 2006 to April 2007,13 patients with esophageal hiatal hernia(typeⅠin 6 and type Ⅲ in 7)were treated by laparoscopy in our hospital.Under a laparoscope,esophageal hiatal hernia was separated by ultrasonic scalpel,and then repaired using Bard CruraSoft PTFE/ePTFE Mesh with Ethicon Endopath Multifieed Stapler.Afterwards,Toupet partial fundoplication was performed.Results The operation was completed in all the cases without converting to open surgery.The mean operation time was 142 min(115-185 min);mean intraoperative blood loss was 75 ml(25-120 ml);mean time to the first flatus and oral feeding was 32 h(26-37 h);and mean postoperative hospital stay was 4 d(3-6 d).The patients were followed up for 4-11 mon(mean 6.5 mon).The symptoms disappeared in 1 month.Three months after the operation,barium examination found no recurrence of the hernia in the 13 cases.Conclusions Laparoscopic repair of esophageal hiatal hernia with mesh combined with Toupet partial fundoplication is a safe and minimally invasive operation.The method is worth being widely used.

Objective To study the effect of fat emulsion intravenous infusion on serum free fatty acids(FFAs) in rats.Methods 24 male Wistar rats were divided randomly into 3 groups,8 rats in each group.(1)Control group(NS),the rats were infused with normal saline intravenously and regular chow;(2)Group LCT,infused with 10% intralipid fat emulsion intravenously;(3)Group MCT/LCT,infused with 10% lipofundin fat emulsion. Group LCT and group MCT/LCT were continuously received equal calorie,nitrogen and volemin in 'All-in-One'solutions. Serum samples were drawn on the 8th day after PN for fatty acid determination. Results The FFAs in Group LCT and group MCT/LCT were remarkably higher than that in control group, but no difference between Group LCT and group MCT/LCT. Conclusions Fat emulsion intravenous infusion can increase the serum free fatty acids considerately.

Description of the tasks provided by the hospital to Beijing Olympic Games and their characteristics, and a summary of the practice and experiences in the course. For example, a general view of hospital mission, reasonable tasks scheduling, and handling of the four relationships. It holds that medical institutions need to take the opportunity of providing medical services to large international events to upgrade and improve themselves, standardize their management, reinforce normalization in medical practice, and better their brand marketing awareness.

Objective To investigate the clinical characteristics of idiopathic retroperitoneal fibrosis (IRF) and its diagnosis and treatment. Methods Data of 27 IRF cases admitted into our hospital during recent 8 years were retrospectively analyzed. Result The main clinical manifestations of IRF included abdominal pain, lumbago, mass in retroperitoneal cavity and ureteral obstruction. The main diagnostic approach to IRF was the image examination. Preoperative correct diagnosis was established in 85 2% of cases. Ureterolysis and wrapping up with the omentum was performed in 21 cases of ureteral obstruction. Two cases suffering from renal artery (RA) stenosis were relieved with arteria renalis lysis. One superior mesenteric artery (SMA) stenosis was managed by arterial lysis. Twenty six cases were cured and one case died postoperatively. Conclusion IRF has nonspecific clinical manifestations. The preoperative diagnosis depends on the image characteristics. The treatment mainly consists of the relief of the obstructive symptoms.
