Objective To explore the significance of blood coagulation disorder in acute pancreatitis(AP) of the elderly and its treatment with prostaglandin E_1.Methods Prothrombin time(PT),partially activated thromboplastin time(APTT) and fibrinogen(FIB) in cases of AP with ages over 60 were checked and compared with those in groups of AP with ages under 60 and normal control subjects.10 cases of AP of the elderly with elevated FIB were treated with prostaglandin E_1.Results Compared with groups of AP with ages under 60 and the normal subjects,FIB was significantly higher in cases of AP of the elderly with the highest in patients of SAP.8 out of 10 aged AP patients with elevated FIB was successfully treated with prostaglandin E_1.Conclusion Patients of AP may present with blood coagulation disorders especially in aged patients.Aged patients with elevated fibrinogen may predispose to SAP.Prostaglandin E_1 may be effective in this occasion.

Objective To study the effect of PGE_1 injection on hepatorenal syndrome.Methods 64 patients with hepatorenal syndrome were divided into two groups at random,33 cases in treatment group and 31 cases in control group.On the basis of complex treatment of the contrast group were added PGE_1 of 200?g,dissolved at 10% glucose liquid 100ml,ivgtt,qd,the course of treatment is 2 weeks.Results The improvement which treated the liver function of the group was superior to the contrast group(P

Objective To investigate the relationship between serum HBV.M.alanine transaminase(ALT) and hepatic tissue pathology in patients with chronic hepatitis B.Methods The serum HBV.M.liver function in 133 patients with chronic hepatitis B were measured,and these patients underwent percutaneous liver biopsy by colour Echo.All these patients were divided into eight groups according to HBeAg and HBV DNA positive or negative,ALT normal or not.Hepatic necrosis inflammation grade and hepatic fibrosis stage in the groups were compared.Results Hepatic histology of all these patients showed inflammation and necrosis and different degree fibrosis.In serum ALT normal patients,liver biopsy still showed different degrees inflammation and hepatic fibrosis degrees partly,even showed hepatocirrhosis.In serum ALT abnormal and HBeAg negative patients with chronic hepatitis B patients,hepatic tissue inflammation and fibrosis degrees were more serious,hepatic tissue pathology was out of proportion to the degree of serum HBV reproduction.Conclusion Judgment of disease activity doesn't only depend on the serum transaminases and the degree of serum HBV DNA replication.When clinical choosing indication of antiviral therapy,value of liver biopsy should not be substituted.Liver biopsy in chronic hepatitis B should be regarded as main basis of judgment the hepatitis activity.It also should be regarded as main basis if antiviral therapy is conducted.

Objective To compare effects between laparoscopic appendectomy(LA) and open appendectomy(OA) for acute appendicitis in children.Methods A total of 95 children with acute appendicitis from July 2000 to July 2005 were given either LA(LA Group,n=50) or OA(OA Group,n=45).The surgical outcomes and curative effects were compared between the two groups.Results The operation was successfully completed in both of the groups.No bleeding,intestinal fistula,or stump appendicitis was seen.There was no difference in the operation time between the LA Group(38.8?17.4 min) and the OA Group(41.9?15.8 min)(t=-0.905,P=0.368).The time to first defecation was significantly shorter in the LA Group(26.4?7.2 h) than in the OA Group(39.7?8.8 h)(t=-8.094,P=0.000).Appendiceal perforation was found in 29 children in the LA Group and 26 children in the OA Group,without significant difference(?~2=1.633,P=0.983),but the incidence of wound infection was significantly higher in the OA Group(11 children) than in the LA Group(2 children)(?~2=8.381,P=0.004).A drainage placement was required in 3 children in the LA Group and 9 children in the OA Group,with significant difference(?~2=4.206,P=0.040).The LA Group had significantly shorter time to normal temperature(55.4?16.2 h) than the OA Group(77.8?30.6 h)(t=-4.522,P=0.000),shorter hospital stay(5.4?1.3 d) than the OA Group(13.4?6.5 d)(t=-8.520,P=0.000),but higher hospitalization costs(6 117.9?836.5 yuan) than the OA Group(4 528.6?527.1 yuan)(t=10.937,P=0.000).Conclusions Laparoscopic appendectomy is superior to open surgery for acute appendicitis in children because of its advantages of minimal invasion,little pain,early recovery,good cosmetic appearance,low complication rate,and short hospital stay.

Objective To evaluate the value and clinical efficacy of amputation of secondary structures of the spleen pedicel for laparoscopic splenectomy(LS).Methods Twenty-one cases of idiopathic thrombocytopenic purpura(ITP) and 1 case of splenic cyst were given a 4-port laparoscopic splenectomy.After the spleen was mobilized,a non-traumatic forceps was used to clip the pedicel at the site 3~5 cm from the hilus of spleen for the control of hemorrhage.The serosa on the spleen pedicel was opened by using a harmonic scalpel.Then secondary structures of the splenic arteries and veins,one by one,were disconnected from without upward,double ligated with the Hem-o-lok clips,and severed with the harmonic scalpel.The spleen was placed into an extraction bag,broken into small pieces,and removed from the extraction incision.Results The laparoscopic splenectomy was successfully completed in all the 22 cases.The operative time was 75~180 min(mean,117 min),and the estimated intraoperative blood loss was 20~280 ml(mean,87 ml).All the patients got out of bed and began to take food at 1~2 days after operation. The length of postoperative hospitalization was 5~11 d(mean,5.6 d).There were 1 case of incisional subcutaneous hematoma and 1 case of subcutaneous emphysema.Follow-up for 1.5～52 months(mean,19.3 months) in the 22 cases revealed no surgery-related complications.Conclusions The amputation of secondary structures of the spleen pedicel is a relatively safe and effective measure for completing laparoscopic splenectomy.

Objective To investigate the clinical value of two kinds of endoscopic thyroidectomy for thyroid diseases.Methods Endoscopic thyroidectomy via breast approach or axillary approach was performed in 98 cases from December 2003 to August 2005.The subcutaneous space beneath the breast area and the subplatysmal space in the neck were bluntly dissected through a 5-mm incision.The CO_2 was insufflated at the pressure of 8~10 mm Hg to create an operative space.Three trocars were inserted.The dissection of the thyroid parenchyma and vessels was performed endoscopically by using an ultrasonically activated scalpel.The recurrent laryngeal nerve,the superior laryngeal nerve,and the parathyroid glands were preserved carefully.There were 1 case of lobectomy on one side and partial thyroidectomy on the other side,18 cases of unilateral lobectomy,12 cases of bilateral subtotal thyroidectomy,46 cases of unilateral subtotal lobectomy,and 21 cases of resection of thyroid mass. Results The operation was successfully completed in all the 98 cases,without conversions to open surgery.No complications were noted.The operative time was 69.1?29.0 min,the estimated blood loss was 37.9?10.6 ml,and the postoperative hospital stay was 3.5?0.7 days.The drainage tube was removed at 24~36 hours after operation.Two cases of thyroid cancer were followed for 24 months without recurrence.The remaining 96 cases were followed for 6~28 months(mean,16 months) without recurrence.Conclusions Endoscopic thyroidectomy via breast or axillary approach is feasible and safe,giving patients satisfactory cosmetic results.

Objective To study the effect and value of the application of the median umbilical fold in laparoscopic treatment for indirect inguinal hernia in children.Methods A total of 105 cases of pediatric indirect inguinal hernia(including 32 cases of incarcerated hernia, 25 cases of bilateral hernia,and 6 cases of recurrent hernia after open surgery) was treated with laparoscopic high ligation of the hernia sac and repair with the median umbilical fold from January 2004 to August 2005.The operation was performed through two or three trocars.Under laparoscopic visualization,the internal ring was identified for a purse-string suture.Then the median umbilical fold was sutured on the internal ring to repair the defect.Results The operation was successfully performed under laparoscope in all the 105 cases.The operative time was 10~25 min(mean,15 min) for unilateral hernia and 20~35 min(mean,25 min) for bilateral hernia.The intraoperative blood loss was hardly seen.The length of hospital stay was 2~3 days.The postoperative recovery was uneventful,without intestinal adhesion,infection,or hematoma of the scrotum.Follow-up observations in the 105 cases for 5~24 months(mean,18 months) found no recurrence.Conclusions Laparoscopic high ligation of the hernia sac and repair with the median umbilical fold is safe and effect for pediatric indirect inguinal hernia,with advantages of mini-invasion,simple performance,short operation time,low complication rate,and quick recovery.

Objective To study the efficacy of laparoscopic pull through proctectomy for the treatment of rectal cancer. Methods There were 60 patients colonoscopically diagnosed as having rectal cancer (3~12 cm from the anal margin). Laparoscopic pull through proctectomy was performed. The distal tumor-free margin was about 2 cm. Results All the operations were performed successfully, without conversions to open surgery. The operating time was 89~179 min (120?25 min), the blood loss was 48~147 ml (75?26 ml), the length of hospital stay was 5~12 d (8.3?1.5 d), and the hospitalization expenditure was 8 680~15 800 yuan (9 900?750 yuan). Follow-up observations in the 60 patients for 12~25 months (mean, 22.3 months) showed no intraabdominal hemorrhage, anal stenosis, or intestinal leakage. Fecal incontinence was not seen at 2 postoperative month. One patient was found local recurrence after 12 months and underwent a second laparoscopic resection. Conclusions Laparoscopic pull through proctectomy for rectal cancer is safe, effective, and minimally invasive.

Objective To explore the efficacy of laparoscopic hepatectomy in combination with radiofrequency ablation and Iodine-125 brachytherapy in the treatment of hepatic carcinoma.Methods The study included 26 cases of hepatic carcinoma(left-sided,12 cases;right-sided,11 cases,both-sided,3 cases).There were 34 tumor lesions,with a maximum diameter of 2.8～13.0 cm.All the patients underwent laparoscopic hepatectomy in combination with radiofrequency ablation and Iodine-125 brachytherapy.Results The combination operation was successfully completed in all the cases,without conversions to open surgery.During the operation,2 new tumor lesions were founded by laparoscopic ulstrasound.Among the 36 lesions,only harmonic scalpel vaporization and Iodine-125 seeds implantation was performed in 8 cases of posterior right lobe lesions,and laparoscopic hepatectomy in combination with radiofrequency ablation and Iodine-125 seeds implantation was conducted in 28 cases of margin lesions.Follow-up checkups for 12～25 months(mean,22.3 months)showed a 1-year survival rate of 92.3%(24/26).Local tumor recurrence was seen in 3 out of 36 lesions.No severe complications occurred.Conclusions Combination of laparoscopic hepatectomy,radiofrequency ablation,and Iodine-125 brachytherapy for treating hepatic carcinoma is safe and minimally invasive,with a rapid recovery and a high survival rate.
