AIM:To compare the long-term outcome of percutaneous vs surgical radiofrequency ablation(RFA) for hepatocellular carcinoma(HCC) in dangerous locations.METHODS:One hundred and sixty-two patients with HCC in dangerous locations treated with percutaneous or surgical RFA were enrolled in this study.The patients were divided into percutaneous RFA group and surgical RFA group.After the patients were regularly followed up for a long time,their curative rate,hospital stay time,postoperative complications and 5-year local tumor progression were compared and analyzed.RESULTS:No significant difference was observed in curative rate between the two groups(91.3% vs 96.8%,P = 0.841).The hospital stay time was longer and more analgesics were required while the incidence of bile duct injury and RFA-related hemorrhage was lower in surgical RFA group than in percutaneous RFA group(P < 0.05).The local progression rate of HCC in dangerous locations was significantly lower in surgical RFA group than in percutaneous RFA group(P = 0.05).The relative risk of local tumor progression was 14.315 in percutaneous RFA group.CONCLUSION:The incidence of severe postoperative complications and local tumor progression is lower after surgical RFA than after percutaneous RFA.

AIM:To evaluate the difference in diagnostic performance of hydro-stomach computed tomography(CT) to detect early gastric cancer(EGC) between blinded and unblinded analysis and to assess independent factors affecting visibility of cancer foci.METHODS:Two radiologists initially blinded and then unblinded to gastroscopic and surgical-histological findings independently reviewed hydro-stomach CT images of 110 patients with single EGC.They graded the visibility of cancer foci for each of three gastric segments(upper,middle and lower thirds) using a 4-point scale(1:definitely absent,2:probably absent,3:probably present,and 4:definitely present).The sensitivity and specificity for detecting an EGC were calculated.Intraobserver and interobserver agreements were analyzed.The visibility of an EGC was evaluated with regard to tumor size,invasion depth,gastric segments,histological type and gross morphology using univariate and multivariate analysis.RESULTS:The respective sensitivities and specificities [reviewer 1:blinded,20%(22/110) and 98%(215/220);unblinded,27%(30/110) and 100%(219/220)/reviewer 2:blinded,19%(21/110) and 98%(216/220);unblinded,25%(27/110) and 98%(215/220)] were not significantly different.Although intraobserver agreements were good(weighted κ = 0.677 and 0.666),interobserver agreements were fair(blinded,0.371) or moderate(unblinded,0.558).For both univariate and multivariate analyses,the tumor size and invasion depth were statistically significant factors affecting visibility.CONCLUSION:The diagnostic performance of hydrostomach CT to detect an EGC was not significantly different between blinded and unblinded analysis.The tumor size and invasion depth were independent factors for visibility.

AIM:To compare the efficacy and safety of paclitaxel combined with fluorouracil plus cisplatin(PCF),and oxaliplatin combined with fluorouracil plus leucovorin(FOLFOX-4) regimens for advanced gastric cancer(AGC).METHODS:Ninety-four patients with AGC were randomly assigned to receive paclitaxel(50 mg/m2 iv) on days 1,8 and 15,cisplatin(20 mg/m2 iv) and ? uorouracil(750 mg/m2 iv) on days 1-5,or oxaliplatin(85 mg/m2 iv) and leucovorin(200 mg/m2 iv) on day 1,followed by bolus fluorouracil(400 mg/m2 iv) and fluorouracil(600 mg/m2 iv) on days 1 and 2.The primary end point was the 1-year survival time.RESULTS:The overall response rate(ORR) of the pa-tients was 48.0% and 45.5% to PCF and FOLFOX-4,respectively.The disease control rate(DCR) of PCF and FOLFOX-4 was 82.0% and 81.8%,respectively.The median survival times(MSTs) of the patients were 10.8 and 9.9 mo,respectively,after treatment with PCF and FOLFOX-4.The 1-year survival rate of the patients was 36.0% and 34.1%,respectively,after treatment with PCF and FOLFOX-4.No significant difference was observed in ORR,DCR,MST or 1-year survival rate between the two groups.The most common adverse events were anemia,nausea and vomiting,and grade 3/4 alopecia in PCF treatment group,and anemia,grade 1/2 neurotoxic effect and grade 3/4 neutropenia in FOLFOX-4 treatment group.CONCLUSION:Patients with AGC have a similar response rate to PCF and FOLFOX-4 regimens with a similar survival rate.The PCF and FOLFOX-4 regimens are efficacious and tolerable as a promising therapy for AGC.

AIM:To compare the mid-term outcomes of laparoscopic calibrated Nissen-Rossetti fundoplication with Dor fundoplication performed after Heller myotomy for oesophageal achalasia.METHODS:Fifty-six patients(26 men,30 women;mean age 42.8±14.7 years)presenting for minimally invasive surgery for oesophageal achalasia,were enrolled.All patients underwent laparoscopic Heller myotomy followed by a 180°anterior partial fundoplication in 30 cases(group 1)and calibrated NissenRossetti fundoplication in 26(group 2).Intraoperative endoscopy and manometry were used to calibrate the myotomy and fundoplication.A 6-mo follow-up period with symptomatic evaluation and barium swallow was undertaken.One and two years after surgery,the patients underwent symptom questionnaires,endoscopy,oesophageal manometry and 24 h oesophago-gastric pH monitoring.RESULTS:At the 2-year follow-up,no significant difference in the median symptom score was observed between the 2 groups(P=0.66;Mann-WhitneyU-test).The median percentage time with oesophageal pHvs 0.35;range 0-2)(P<0.0001;Mann-WhitneyU-test).CONCLUSION:Laparoscopic Dor and calibrated Nissen-Rossetti fundoplication achieved similar results in the resolution of dysphagia.Nissen-Rossetti fundoplication seems to be more effective in suppressing oesophageal acid exposure.

AIM:To compare the fast-track rehabilitation program and conventional care for patients after resection of colorectal cancer.METHODS:One hundred and six consecutive patients who underwent fast-track rehabilitation program were encouraged to have early oral feeding and movement for early discharge,while 104 consecutive patients underwent conventional care after resection of colorectal cancer.Their gastrointestinal functions,postoperative complications and hospital stay time were recorded.RESULTS:The restoration time of gastrointestinal functions in the patients was significantly faster after fasttrack rehabilitation program than after conventional care(2.1 d vs 3.2 d,P vs 26.9%,P vs 15.4%,P vs 7 d,P vs 8.7%).CONCLUSION:The fast-track rehabilitation program can significantly decrease the complications and shorten the time of postoperative hospital stay of patients after resection colorectal cancer.
