ABSTRACT
Objective To assess the safety and influence of the stents extended into inferior vena cava in patients with non-thrombotic iliac vein lesions (NIVLs) on the bilateral iliac vein blood flow.Methods We retrospectively reviewed data from July 2008 to June 2017 in 197 patients with NIVLs who underwent iliac vein stenting and complete follow-up was obtained at our institution.Of these patients,stents extended into IVC more than 10 mm in 141 cases,less than 5 mm in 22 cases,and 34 cases were between 5 and 10 mm.Restenosis and thrombosis of bilateral iliac vein and patency of these stents were assessed in the follow-up.The count data were expressed by percentage (％),and the sample comparison rate was analyzed by Fisher exact test formula.The measurement data were first tested for normal distribution and homogeneity of variance,and then corrected t test.Results The two hundred and five iliac vein stents were placed in 197 patients.During a mean follow-up of 58.7 months (6 to 98 months),there were no thrombosis occurred in the contralateral iliac vein,6 patients suffered restenosis or new thrombosis in the stents,the incidence between stenting positions less than 5 mm (13.6％,3/22) and those more than 5 mm (3.43％,6/175) was sighificantly different (P ＜0.001),and 5 of 6 patients had a good patency after endovascular therapy.During the fllow-up,the primary and assisted-primary patency rates were 97.0％ and 99.5％.Conclusions From these data,it appears that there is a very high patency rates of the stenting treatment for the NIVLs,and it is safe for the stents extended into the IVC,stenting across the iliocaval confluence can result in a small number of new contralateral thromboses.Moreover,the risk of stents restenosis or occlusion is high when stents are not extended into IVC.
ABSTRACT
Objective To explore the value of endovenous laser treatment (EVLT) in treating the variceal ulcer of lower extremities (VULE).Methods Twenty cases of chronic venous insufficiency with VULE were treated with endovenous laser and received regular postoperative follow-up survey.Results No complication,such as burning of skin happened,all superficial varicose veins disappeared,and most of ulcers were healed within 2 -4 weeks after EVLT.Conclusion EVLT is one of the important methods which is minimally invasive and safe to treat VULE.
ABSTRACT
Objective To explore the feasibility,the safety,D2 lymph node dissection and clinical outcomes of laparoscope-assisted radical gastrectomy lot advanced gastric cancer.Methods The clinica data of 47 cases with advanced gastric treated with laparoscope-assisted radical gastrectomy were analyzed retrospectively.Results Laparoscope-assisted radical gastrectomy,proximal gastrectomy in 25 cases,distalgastrectomy in 11 cases,total gastrectomy in 10 cases;46 were performed Laparoscope-assisted surgery radical gastrectomy successfuly,and the other one was converted to abdominal opening.The average operative time for proximal gastrectomy,distal gastrectomy,and total gastrectomy was(220±55)min,(284±37)min,and (330±50)min,respectivel.The average blood loss in proximal gastrectomy,distal gastrectomy,and total gastrectomy was(150±87)ml,(120±70)ml,and(330±50)ml respectively.The average time of proximal gastrectomy for gastrointestinal function recovery,for the patients to stand up,and for the postoperative hospital stay was(5.1±0.5)d,(3.2±0.8)d and(9.0±1.5)d.The average time of distal gastrectomy for gastrointestinal function recovery,for the patients to stand up,and for the postoperative hospital stay was (4.0±0.8)d,(3.2±1.5)d and(9.0±2.0)d.The average time of total gastrectomy for gastrointestinal function recovery,for the patients to stand up,and for the postoperative hospital stay was(4.1±0.8)d,(3.2±0.8)d and(9.5±2.0)d.The mean total number of retrieved lymph nodes was(21.95±9.88),and the lengths of proximal and distal margins to the tumor were(6.41±2.13)cm and(6.22±1.98)cm respectively.No postoperative deaths or anastomtic fistulas were found.Its short-term outcomes were satisfactory.Conclusion Laparoscope-assisted radical gastrectomy with D2 lymphadenectomy is safe,feasible,which achieves adequate cancer clearance,but the long-term outcome is needed to be observed.
