Objective To compare the difference in recurrence rates between the endovenous laser therapy(EVLT) combined with percutaneous continuous circumsature (PCCS) and simplex EVLT following the treatment of great saphanous vein incompetence through the introduction of propensity score matching (PSM).Methods T the baseline data of 170 patients diagnosed with great saphanous vein incompetence who were treated in Punan Hospital in Pudong New District of Shanghai from 2009 to 2014 were retrospectively analyzed,of which underwent EVLT were 87 cases as EVLT group and EVLT combined with PCCS were 83 cases as EVLT +PCCS group.The groups covariate were balanced based on the PSM function of SPSS software using 1 ∶ 1 nearest neighbor matching method.The recurrence rates of the two groups were estimated by Kaplan-Meier method and the differences between the two groups were evaluated by Log-rank test.Results Sixty-seven pairs of patients were successfully matched.No significant difference between the two matched groups in the basic clinical features.Before PSM,the 1,2,and 3 year cummulative recurrence rates were 3.5％,5.4％ and 7.3％ in the EVLT group,and 0.9％,4.7％ and 4.7％ in the EVLT+PCCS group,respectively,there were no statistically significant differences between the two groups by Log-rank test (P =0.491).After PSM,the 1,2,and 3 year cummulative recurrence rates were 5.2％,5.2％ and 7.1％ in the EVLT group,and 0％,1.0％ and 1.0％ in the EVLT+PCCS group,there were statistically significant differences between the two groups (P =0.031).Conclusion The PSM methods can effectively balanced the covariates of groups in non-randomised study.EVLT combined with PCCS can effectively reduce the recurrence rate after the treatment of great saphanous vein incompetence.

OBJECTIVETo explore the clinical efficacy and safety of gastroepiploic tunnel esophagogastrostomy applied in minimally invasive esophagectomy and gastroesophageal cervical anastomosis.

METHODSClinical data of 137 esophageal cancer patients who received minimally invasive esophagectomy from December 2013 to June 2015 in Department of Thoracic Surgery, Tangdu Hospital, The Fourth Military Medical University were analyzed retrospectively, including 84 patients receiving anastomosis with tubular anastomat (circular staple group), and 53 patients receiving gastroepiploic tunnel anastomosis(tunnel group, position of tunnel anastomosis located in the side of gastrocolic omentum, about 2-3 cm apart from fundus). Incidence of postoperative anastomotic leakage and stricture was compared between two groups.

RESULTSAll the 137 patients completed minimally invasive esophageal surgeries successfully without conversion to open thoracic or abdominal operation. The time for anastomosis was(20.2±3.1) minutes in circular stapler group and (38.9±2.9) minutes in tunnel group respectively, and the difference was statistically significant (t=75.22, P=0.000 0). The incidence of postoperative anastomotic leakage was 21.4%(18/84) in circular stapler group and 0(0/53) in tunnel group respectively, and the difference was statistically significant (P=0.000 3). All the patients were followed up for more than 6 months. During follow-up period, the incidence of postoperative anastomotic stricture was 14.3%(12/84) in circular stapler group and 3.8%(2/53) in tunnel group respectively, and the difference was statistically significant(P=0.047 9).

CONCLUSIONThe gastroepiploic cervical tunnel anastomosis is safe and effective and can reduce the incidence of postoperative anastomotic leakage as well as anastomotic stricture.

OBJECTIVEInvestigate the best surgical resection of esophageal cancer by comparing the efficacy and safety between Ivor-Lewis esophagectomy and Sweet esophagectomy.

METHODSThe relevant literatures comparing Ivor-Lewis esophagectomy with Sweet esophagectomy were searched through PubMed, Embase, the Cochrane Library, Google scholar, CNKI, CBM, VIP, WanFang Data. RevMan 5.2 software was used for data analysis.

RESULTSA total of 4106 patients in 15 studies were reviewed and the data were pooled for analysis. Meta-analysis showed that, compared with the Sweet group, Ivor-Lewis operative time was significantly longer(pooled mean difference=57.40; 95%CI:42.43 to 72.38; P=0.000), operative bleeding was significantly higher(pooled mean difference=28.39, 95%CI:4.06 to 52.72, P=0.02); the number of lymph node dissection significantly more(pooled mean difference=4.19, 95%CI:3.06 to 5.32, P=0.000); No significant difference was present in hospital stay, vocal cord paralysis, chylous leakage, pulmonary complications, anastomotic leakage(all P>0.05). The 5-year survival between the two groups showed no significant difference(P=0.52).

CONCLUSIONSThe two kinds of operation have the same long term effect. Compared with Ivor-Lewis operation, Sweet operation is easier to perform, less time consuming and more tolerable. Ivor-Lewis operation can dissect more lymph nodes than Sweet operation, without increased complications.
