Objective To report evidence-based treatment for 2 case of Ⅱ B stage non-small cell lung cancer. Methods We searched systematic reviews and randomized controlled trials in The Cochrane Library (Issue 2, 2009), MEDLINE (PubMed, January 1970 to June 2009) and ACP Journal Club (1996 to June 2009), and evaluated the evidence. Results The best clinical evidence for Ⅰ and Ⅱ stage non-small cell lung cancer patients showed that in the patients with resectable nonsmall cell lung cancer, postoperative adjuvant radiotherapy and chemotherapy could not improve survival compared with surgery alone. We did not find evidence which indicated that preoperative chemotherapy improved survival in people with resectable non-small cell lung cancer. Conclusion In accordance with the wishes of the patient and family, they do not accept the radiotherapy and chemotherapy, but choose palliative and supportive therapy.
Objective To investigate the clinical curative effect of divided excision and plastic combined with procedure for prolapse and hemorrhoids (PPH) in treatment for circular mixed hemorrhoids. Methods Clinical observation on 120 patients with circular mixed hemorrhoids between May 2007 and May 2008 treated by divided excision and plastic combined with PPH was carried out. Results The mean hospital stay after operation was 7.6 d. The wound healing average time was 11.9 d. The incidence rate of postoperative urinary retention was 5.8% (7/120). Average scores of pain in 3 d after operation: 5.3 points (1-8 points) on day 1, 3.6 points （2-9 points） on day 2, 2.2 points （1-8 points） on day 3. All patients were followed up for 12 months, there were 3 cases of hematochezia， 1 case of prolapse, and 1 case of remained abnormal outgrowth skin; the anus function was normal in all cases without anal stricture or tightening feeling. Conclusions Divided excision and plastic combined with PPH can better treat circular mixed hemorrhoids. This operation can not only completely clear the lesions, but also repair and reconstruct the anus and anal canal, protect its size and function. It is an ideal operation for treatment for circular mixed hemorrhoids.
Objective To investigate the safety and effectiveness of the operation of integrate subparagraph, fenestration, exclusion, cut expansion, seton, tube, and drainage (ISFECSTD) to cure complex anal fistula. Methods Using randomized comparison and multicenter parallel experiment, the total number was 240: 120 patients in study group treated by ISFECSTD, and 120 patients in control group treated by extended cutting and seton operation. Then compared the safety and effectiveness between two groups. Results The clinical recovery rate of the study group was significantly higher than that in the control group （Plt;0.05）. The operation time and wound healing time in study group were significantly less than those in control group, and the scar area after wound healing was smaller than that in control group （Plt;0.01）. The decreased extents of anorectal pressures and rectal capacity feeling function after operation in study group were smaller than those in control group (Plt;0.01). Rectal and anal reflex function and healing of the endostoma, stem, and branch in study group were better than those in control group (Plt;0.05, Plt;0.01). Incidence of anal incontinence after operation in study group was significantly less than that in of anus-rectum structure and function, and has the merits of higher cure rate, shorter time of healing, smaller scar, less pain, etc. The method of ISFECSTD is worth being a new standardized operation in the clinical application.
ObjectiveTo explore the value of potaried technique with Trivex system in treatment for venous skin ulcer with deep venous thrombosis sequelae (DVTS) of lower limbs. MethodsTotal 166 patients with venous skin ulcer with DVTS of lower limbs were included in this study. The patients of operation group (94 patients involving 94 legs) were treated by using potaried technique with Trivex system. The patients of nonoperation group (72 patients involving 72 legs) were treated by using nonoperative method. The clinical indexes of skin infection rate, skin necrosis rate, shrinkage rate of wound area, skin depigmentation rate, ulcer healing rate and ulcer recurrence rate were used to assess the clinical curative effect between two groups on 5, 20, 120 and 360 d after operation or treatment, respectively. ResultsThere were no skin infection and skin necrosis in two groups on 5 d after operation or treatment. The rate of shrinkage of wound area and skin depigmentation of patients in operation group were significantly higher than those in nonoperation group on 20 d after operation or treatment 〔(95.8±2.138)% vs. (68.7±3.125)%，P=0.048; (87.6±1.263)% vs. (12.3±1.324)%， P=0.018〕. The rate of the ulcer healing of patients in operation group was significantly higher than that in nonoperation group on 120 d after operation or treatment (97.9%vs. 8.3%， P=0.014). The rate of the ulcer recurrence of patients in operation group was significantly lower than that in nonoperation group on 360 d after operation or treatment (5.3% vs. 97.2%， P=0.015). ConclusionThe potaried technique with Trivex system can be used as one of the surgical treatment methods for venous skin ulcer with DVTS of lower limbs.
Objective To investigate the best management in treating relapsed biliary calculi after endoscopic sphincterotomy (EST).Methods The clinical data of 96 patients with relapsed biliary calculi after EST in our hospital from February 1999 to February 2009 were retrospectively analysed. The patients were grouped into two groups by the size of calculi under magnetic resonance cholangiopancreatography: surgical group (the size of calculi was bigger than 1.0 cm) in 79 cases and non-surgical group (the size of stone was smaller than 1.0 cm and the patients were performed EST again) in 17 cases. The relapsed biliary calculi rate between two groups were compared. Results In the surgical group, the 79 patients (82.29%) were performed common bile duct exploration, transected common bile duct and choledochojejunostomy with Roux-en-Y anastomosis. In the non-surgical group, the 17 patients (17.17%) were performed EST again. The relapsed biliary calculi rate was 2.63% in the surgical group, 70.59% in the non-surgical group. There was marked difference in the relapsed biliary calculi rate between surgical group and non-surgical group (Plt;0.05). Conclusion The operation treatment is the best way for relapsed biliary calculi after EST, and has good curative effect. The best manner of operation treatment is common bile duct exploration, transected common bile duct and choledochojejunostomy with Roux-en-Y anastomosis.
Objective To compare the clinical effect between neo-adjuvant chemotherapy combined with operation and simple operation under multi-disciplinary team in rectal cancer. Methods A survey of 72 patients with rectal cancer from Nov. 2007 to Mar. 2008 were studied. Patients were divided into two groups using a simple random method: 33 cases in combined therapy group were treated with single period neo-adjuvant chemotherapy as well as operation and 39 cases in control group received operation only. To compare the differences of perioperative period indexes between two groups. Results During the differences of indexes of age, gender, differentiation degree, clinicopathologic stage as well as the distance to dentate line of tumor, there was no statistical significance between combined therapy group and control group (Pgt;0.05). And at the same time, the operative type, operative time and bleeding quantity in operation had no statistically significant difference between two groups (Pgt;0.05). As for the postoperative rehabilitation indexes, the time of vent to normal in combined therapy group was earlier than that in control group, but the intake time was later than that in control group （Plt;0.05）. Falling range from preoperative CEA to postoperative CEA was larger in combined therapy group than that in control group （Plt;0.05）; and the falling range from preoperative WBC to postoperative WBC had no significant difference between two groups （Pgt;0.05）. Conclusion The clinical effect of combined therapy is obviously superior to simple operation, suggesting that neo-adjuvant chemotherapy combined with operation is feasible and safe.
【Abstract】ObjectiveTo study the distal intramural spread of rectal carcinoma, and provide evidence for modification of rectal carcinoma surgery. MethodsSixty patients with rectal carcinoma admitted to the first affiliated hospital of Chongqing university of medical science from November 2001 to October 2002 were included. The specimens were extended to its original size and shape by the fat clearing method. Mesenteric lymph nodes were dissected by using transillumination to examine metastases histologically, then a lymph nodes map was produced which including the site of the primary lesion, the vascular distribution, and the sites of dissected nodes. The specimen below the distal margin of the tumor was cut continuously with 0.5 cm interval then sectioned for histopathological examination. ResultsTumor spread to the distal intramural was observed in 11 of 60 patients (18.3%) with the range within 1.5 cm, of which less than 0.5 cm in 5 case, 5 cm to 1.0 cm in 2 cases, 1.0 cm to 1.5 cm in 4 cases. The tumor invasion was correlated with gross type, histological type and infiltrative depth, but not with sex, age, location of the tumor, size of the tumor, lymph nodes metastases and Dukes stage. Conclusion The range of distal mural excision should exceed 1.5 cm to tumor margin in radical surgery for rectal carcinoma. This rule should be emphasized for patients with poor cell differentiation and deep infiltration.
【Abstract】ObjectiveTo analyze the factors influencing the prognosis of patients with bile duct carcinoma after resection. MethodsThe clinical data of 120 patients with bile duct carcinoma receiving resection in our hospital from 1980 to 2004 were collected retrospectively and clinicopathologic factors that might influence survival were analysed. A multiple factor analysis was performed through Cox proportional hazard model. ResultsThe overall 1year, 3year and 5year survival rates were 71.7%, 32.5% and 19.2% respectively. The single factor analysis showed that the major significant factors influencing survival of these patients were histological type of the lesions, lymph node metastasis, pancreatic infiltration, duodenal infiltration, resected surgical margin, perineural infiltration, peripheral vascular infiltration and depth of tumor infiltration (P＜0.05). Lymph node metastasis, pancreatic infiltration and perineural infiltration were found to be the the statistically significant factors influencing survival by multiple factor analysis through the Cox model. ConclusionThe most important prognostic factors for bile duct carcinoma after resection were lymph node metastasis, pancreatic infiltration and perineural infiltration.
【Abstract】ObjectiveTo discuss how to improve the current status on clinical therapy for advanced gastric carcinoma. MethodsRelated literatures searched on Medline were collected and reviewed. ResultsThe 5th edition of UICC/AJCC TNM staging system of gastric carcinoma is useful to evaluate the prognosis of patients with advanced gastric carcinoma followed by extended lymphadenectomy. There are many factors influencing their prognosis including disease stage, extent of lymphadenectomy, assistant therapy and so on. ConclusionIt is significant for patients with advanced gastric carcinoma to undergo individualized extended lymphadenectomy and comprehensive therapy to improve their prognosis after radical gastrectomy
ObjectiveTo evaluate the significance and effect for surgery of Dukes D stage colorectal carcinoma. MethodsEightytwo cases of Dukes D stage colorectal carcinoma who underwent surgery from 1991 to 1998 were analyzed retrospectively. ResultsTwentyone patients experienced extended resections,29 patients palliative resection, 19 patients sideside anastomosis and 13 patients laparotomy and biopsy of the tumor. Patients with extended resections had significantly long survival time, quality of life in these patients were excellent in 71.4%, good in 23.8%, and fair in 4.8%; whereas quality of life in the group with palliative resections were excellent in 62.1%, good in 17.2%, fair in 13.8%, and poor in 6.9%. The other two groups had a bad postoperative effect, short survival time and poor quality of life. ConclusionIf the patients with Dukes D stage colorectal carcinoma have operative indications,surgical therapy should be actively performed and the postoperative survival rate and quality of life can be improved.
