OBJECTIVETo compare the safety and efficacy between three-field lymphadenectomy and normative Ivor-Lewis two-field lymphadenectomy for thoracic esophageal squamous cell carcinoma METHODS: Clinical data of 375 patients with thoracic esophageal squamous cell carcinoma who underwent three-field lymphadenectomy(3FL) or Ivor-Lewis two-field lymphadenectomy(2FL, Ivor-Lewis) in Fudan University Shanghai Cancer Center during 2013 were retrieved and collected from electronic medical record system. Ninety-one patients received three-field lymphadenectomy (3FL group), including 16 cases of intra-cervical gastro-esophageal anastomosis and 75 cases of intra-thoracic gastro-esophageal anastomosis, while 284 patients received Ivor-Lewis two-field lymphadenectomy (2FL group) with all intra-thoracic gastro-esophageal anastomosis. Short-term outcomes were compared between two groups, including postoperative anastomotic leakage, pneumonia and respiratory failure, chylothorax, reoperation and 90-day death. Total harvested lymph nodes and positive lymph nodes in each group were also compared. A total of 338 patients were enrolled into survival analysis. Survival curve was presented by Kaplan-Meier method.

RESULTSAs compared to 2FL group, the 3FL group had significantly higher ratio of N3 patients [19.8% (18/91) vs. 5.3% (15/284), P=0.000], stageIII( patients [58.2%(53/91) vs. 43.0%(122/284), P=0.007], and upper thoracic cancer patients [12.1%(11/91) vs. 3.5%(10/284), P=0.027]; also the 3FL group had more harvested lymph nodes (40.1±14.6 vs. 25.3±9.4, P=0.000) and more positive lymph nodes (3.3±4.0 vs. 1.7±3.2, P=0.000). With respect to pneumonia and respiratory failure, chylothorax, reoperation and 90-day death, no significant differences were found between the group (P=0.447, P=0.751, P=0.678, P=0.685). The 3FL group had a significantly higher incidence of anastomotic leakage than 2FL group [7.7% (7/91) vs. 1.8% (5/284), P=0.011], while its incidence of intrathoracic anastomosis leakage was 4.0% (3/75), which was not significantly different with 1.8%(5/284) of 2FL group (P=0.372). Median follow-up was 33 months. Overall 1-, 2-, 3-year survival rates were 94%, 81% and 70%, while 1-, 2-, 3-year survival rates of 3FL group were 90%, 73% and 66%, of 2FL group were 95%, 84% and 72%, respectively, without significant differences between the two group(P=0.135). Further subgroup analysis showed that no significant differences of postoperative survival in stage I(, II( and III( patients were observed between the two groups (P=0.541, P=0.511, P=0.402), meanwhile no significant differences of postoperative survival in patients with metastasis and without metastasis were found between the two groups as well (P=0.985, P=0.233).

CONCLUSIONSThree-field lymphadenectomy can be performed with acceptable perioperative morbidity and mortality. The prognosis value of three field lymphadenectomy needs further investigation. Patients with thoracic esophageal squamous cell carcinoma may have favorable survival through normative Ivor-Lewis two-field lymphadenectomy.

OBJECTIVE: To evaluate the clinical efficacy of percutaneous mechanical thrombectomy (PMT) combined with percutaneous transluminal angioplasty (PTA) in the treatment of iliofemoral deep vein thrombosis. METHODS: Ninety-four patients with iliofemoral deep vein thrombosis were identified in this retrospective study in our institution from November 2015 through December 2017. Patients were divided into two groups:PMT+PTA group (=50) and PMT only group (=44). Clot lysis rates, the retrieving and the embolism of the interior vena cava filter, as well as the incidence of complications were compared between two groups. The changes of serum creatinine, lactate dehydrogenase and hemoglobin were also measured perioperatively. RESULTS: All procedures were completed successfully. The average clot lysis rate was higher and the procedure time was shorter in PMT+PTA group than those in PMT group (both <0.01). No significant differences were found in the rates of venous stenosis, catheter-directed thrombolysis and stent placement between two groups (all >0.05). The interior vena cava filter was taken out in 82.0% (41/50) patients of PMT+PTA group and 81.8% (36/44) patients of PMT group (>0.05). There were no significant differences of the changes in serum creatinine, lactate dehydrogenase and hemoglobin (all >0.05). In PMT+PTA group, symptomatic pulmonary embolism and puncture bleeding occurred in 1(2.0%) and 2(4.0%) patients, while in PMT group, it was 0 and 2(4.5%), respectively (>0.05). CONCLUSIONS PMT combined with PTA is more effective than PMT alone for the treatment of iliofemoral deep vein thrombosis with less procedure time and without more incidence of pulmonary embolism.

OBJECTIVE: To evaluate the long-term efficacy of percutaneous mechanical thrombectomy (PMT) combined with stent implantation in treatment of acute iliofemoral vein thrombosis. METHODS: Seventy patients with acute iliac vein thrombosis were treated with PMT combined stent implantation in Ningbo No.2 Hospital from November 2015 to November 2017. During the follow-up, the improvement of blood flow was evaluated, the occurrence of post-thrombotic syndrome was assessed by the Villalta rating scale, and the stent patency was examined with lower extremity ultrasound or angiography. RESULTS: The blood flow was significantly improved after procedure in all 70 patients, including 62 cases (88.6%) of grade Ⅲ clearance, 5 cases (7.1%) of grade Ⅱ clearance, and 3 cases (4.3%) of grade Ⅰ clearance. No significant complications occurred during the treatment. The patients were followed up for (15.0±2.5) months. During the follow-up, 64 patients (91.4%) had unobstructed stents, and 9 patients (12.8%) had post-thrombotic syndrome. CONCLUSIONS PMT combined with stent implantation is effective in the treatment of acute iliac vein thrombosis with a high medium-and long-term stent patency rate.
