Objective To evalute the indication and clinical application value of microwave abla-tion in spleen-preserving surgery in treament of patients with traumatic rupture.Methods The clinical data of 45 patients with traumatic splenic rupture were retrospectively analyzed.Spleen preserving surgery was feasible by preoperative CT evaluation and intraoperative observation.36 patients received simply mi-crowave ablation,and 9 cases received microwave ablation assisted partial splenectomy.Postoperative com-plications were observed,and the changes of platelet in peripheral blood were detected before and after op-eration in the 3 th,7th,14th day to evaluate the function of spleen.Results 15 patient was complicated with left pleural effusion,1 patient was complicated with splenic fossa fluid associated with infection.Dur-ing the follow-up of at least 2 months,No patients had postoperative bleeding,hemoglobinuria,gastrointes-tinal leak,deep vein thrombosis and pancreatic leak complications,no deaths.Seven days after microwave ablation spleen-preserving surgery,blood platelet count were significantly higher than the levels before the operation (P <0.05)in spleen-preserving patients.Platelets were no statistically significant after operation in the 3 th,14thday compared with the preoperative(P >0.05).The CT scan and the ultrasonic examina-tion that reviewed after operation in the 30-60th day showed good in spleen imaging in spleen-preserving patients,No patients had portal vein thrombosis.Conclusion Microwave ablation spleen-preserving sur-gery in the treatment of partial traumatic splenic rupture will be a safe and effective operation which could expand the spleen-preserving indication and be used in clinical practice.

Objective To evaluate the clinical efficacy of dendritic cells-cytokine induced killer cells combined with surgical treatment for primary liver cancer.Methods Totally 78 patients with primary liver cancer were randomly divided into experiment group (n =30) and control group (n =48).The patients in experiment group received hcpatectomy combined with dendritic cells-cytokine induced killer cell treatment while those in control group were given hepatectomy treatment.The median time to recurrence,progression-free survival,survival and quality of life were evaluated.Observed side effects of cell therapy in experiment group.Results Experiment group received a total of dendritic cells-cytokine induced killer cell treatment 78,an average of 2.6 times per person.Fever occured in 8 patients who received dendritic cells-cytokine induced killer cell treatment.After one cycle of immune therapy,the KPS score of 20 cases was improved,8 cases were stable and and 2 case was worsen in the experiment group.The KPS score of 10 cases were improved,32 cases were stable and and 6 cases were worsen in the control group,and the difference is statistically significant (P ＜ 0.05).The progression-free survival rates for 1,2 and 3 years in the experiment group were 73.3％,40.0％,23.3％ and 68.7％,27.0％,14.5％ in the control groups,respectively.The progression-free survival rates in the experiment group were improved compared to the control group and the difference is statistically significant (P ＜ 0.05).The median time of recurrence in the experiment group were (16.9 ± 2.6) months and (13.5 ± 2.9) months in the control group,respectively (P ＜ 0.05).The 1-2-3-years survival rates in the experiment group were 85.0％,50.0％,35.0％ and 85.0％,40.0％,23.3％ in the control group respectively.There was no statistically significant difference between these two groups (P ＞ 0.05).Conclusions Dendritic cellscytokine induced killer cells combined with surgical treatment on primary liver cancer is safe and effective,it can improve quality of life,and delay the recurrence time after surgery.But not improve long-term survival.

Objective To Discuss the effect of surgical treatment from enteral and parenteral nutrition that in perioperative period of hepatolithiasis patients who taking hepatectom.Methods Retrospective analysis 55 cases who taking hepatectomy treatment in Fuling Central Hospital of Chongqing City from March 2011 to March 2015,all elective operations.According to the different nutrition support methods in perioperative period,randomly divided into enteral and parenteral group (n =25) and parenteral nutrition group (n =30).Results The postoperative complication rate and recovery time of bowel function in patients with enteral and parenteral nutrition,it was better than parenteral nutrition group (28 ％ vs 40％),[(4.50 ± 0.50) d vs (5.50 ± 1.00) d],the difference had statistical significance (P ＜ 0.05).Before and after operation in two groups of body mass index [(22.10 ± 1.80) vs (22.30 ± 1.70)],prealbumin impovement [(130.00 ± 45.00) mg/L vs (124.00 ± 55.00) mg/L],albumin impovement [(35.50 ± 2.72) g/L vs (36.50 ± 2.70) g/L],had no statistical significance (P ＞ 0.05).Conclusion Enteral and parenteral nutrition in perioperative can significantly improve the nutritional status of patients and the effect of surgical treatment.

Objective To investigate the clinical effect and safety of spleen-preserving surgery by microwave tissue coagulation (MTC) therapy.Methods Retrospectively analyzed the clinical data of 45 cases undergoing spleen retaining surgery by MTC therapy (observation group) and comparative study was used on another 45 cases experiencing splenectomy (comparative group),clinical effect and complications were compared.All cases were patients from Jan.2010 to Jun.2013.Results All cases were cured.Hospitalization of observation group is obviously shorter than that of comparative group(P =0.007).The rate of complication in observation group(4.44％) is lower than that in comparative group (20.00％),but the time and amount of bleeding in operation of observation group is much more than that of comparative group.Conclusion MTC can effectively guarantee patients safety,shorten hospital stay,and be worthy of popularization.
