Objective To evaluate short-term therapeutic effects of laser therapy combined with high ligation of the great saphenous vein in the treatment of varicose veins in the lower extremities. Methods Endovenous laser treatment combined with high ligation of the great saphenous vein was performed on 46 patients with varicose veins in the lower limbs (55 limbs). Results The operation time was 30-65 min (mean, 48 min) for each limb. The number of incisions was 1-5 (mean, 2.8) in each limb. Hospital stay after operation was 3-5 d (mean, 3.6 d). Postoperatively, subcutaneous bleeding occurred in 11 limbs (20%), skin burn was seen in 6 limbs (11%). Among the patients, 42 (50 limbs) were followed up for 2-19 months (mean, 13.5 months), during which no recurrence was found. Conclusion Laser treatment combined with high ligation of the great saphenous vein is effective for varicose veins in the lower extremities.

Objective To study the treatment effect of multilevel atherosclerotic occlusive disease of lower extremity. Methods From July 2004 to January 2008,intraoperative iliac balloon angioplasty and stenting combined with blood vassel prosthesis or autogenous reversed great saphenous vein bypass were performed on 32 patients suffering from lower extremity multilevel atheresclerotic occlusive disease. Results Surgical procedures were technically successful in all patients. The effect was good,intermittent claudication disappear, and rest pain improved. Preoperative vs postoperative ABI was 0.28±0.14 vs 0.65±0.18 (P<0.05 ).Thirty patients were followed up,the mean following period was 18 months (range of 3-36 months).Conclusions Simultaneous intravaseular interventional therapy combined with vascular bypass are effective in the treatment for patients with severe and multilevel atheroselerotie occlusive disease of lower extremity, the operation is less traumatic and the procedures are easy to do.The result is satisfactory.

Objective To evaluate percutaneous AngioJet thrombectomy in the treatment of iliofemoral deep venous thrombosis (DVT).Methods A total of 36 patients with 38 legs of lower extremity DVT treated by AngioJet mechanical thrombectomy from Feb 2016 to Dec 2016 were analyzed retrospectively.The effect of lower limb venous recanalization was evaluated by observing the intraoperativeangiography and the results of postoperative follow-up including complaints,signs,and lower extremity venous ultrasound or CT and Villalta scores.Results Thrombosis was completely dissolved by AngioJet thrombectomy device in 32 out of 38 legs (84.2％) at first stage.Slight bleeding occurred in 4 cases,1 patient could not tolerate the operation.23 patients were followed-up for 6 months,venous patency was present in 21 of 23 patients (91.3％).11 patients complete the one-year follow-up,9 patients (81.8％) were in the 0-4 Villalta group.Conclusions AngioJet can effectively and safely remove thrombus in the lower extremity deep venous system.It is especially advantageous for patients who have contraindications for thrombolysis with a satisfactory short term venous patency.

In order to study the significance of CD276 and CD133 in the development and progression of colorectal cancer (CRC),the expression of CD276 and CD133 was detected by immunohistochemistry in CRC and precancerous lesions.The results showed that the intensity of CD276 and CD133 in CRC samples was higher than that in adenoma group and non-adenoma group.CD276 and CD133 single and double positive expression were significantly correlated with CRC lymph node metastasis,distant metastasis and survival.CD276 and CD133 are significantly correlated to the development and progression of CRC and associated with poor prognosis.

Objective:To investigate the clinical advantages of absorbable barbed wires in laparoscopy combined with choledochoscopy treatment of gallbladder polyps.Methods:The clinical data of 103 patients with gallbladder polyps who received laparoscopy combined with choledochoscopy treatment in The First People's Hospital of Lianyungang from February 2016 to March 2018 were retrospectively analyzed. Sixty-five patients in the observation group underwent gallbladder wall sutures with absorbable barbed wires, and thirty-eight patients in the control group underwent gallbladder wall sutures with common absorbable wires. The operative time, gallbladder wall suture time, intraoperative blood loss, average hospitalization time, and postoperative bile leakage were compared between the two groups.Results:There were no significant differences in intraoperative blood loss and average hospitalization time between the two groups ( P = 0.312, P = 0.114). In the observation group, gallbladder wall suture time and operative time were (5.58 ± 1.14) minutes and (60.71 ± 11.03) minutes, respectively, which were shorter than (6.32 ± 1.04) minutes and (68.24 ± 9.61) minutes in the control group ( t = 3.23, 3.50, P = 0.002, 0.001). No bile leakage occurred in the observation group and bile leakage occurred in four (10.5%) patients in the control group. There was a significant difference in bile leakage between the observation and control groups ( χ2 = 4.57, P = 0.032). Conclusion:Absorbable barbed wires for gallbladder wall sutures during operation in laparoscopy combined with choledochoscopy treatment of gallbladder polyps is safe and feasible. It can markedly shorten gallbladder wall suture time and operative time, decrease the incidence of bile leakage, and has a clinical advantage over common absorbable wires.

To access the efficacy of stents for spontaneous isolated dissection of the superior mesenteric artery (SIDSMA). The study is a prospective single-arm study which has been registered on Clinical Trials (NCT03916965). Clinical data and follow-up information of the SIDSMA patients who received stent implantation in the First Affiliated Hospital of Zhejiang University during April 1, 2019 and September 30, 2019 were collected. The patients were recommended to be followed up at 1, 3, 6 and 12 months. A total of 34 patients were enrolled. Their mean age was (54±8) years. Abdominal pain was the most common symptom. Patients received (2.1±0.6) stents on the average. Post-operation hospital stay was (2.7±1.6) days, and the patients were followed up for (2.3±1.9) months (CT angiography) and (5.5±1.7) months (clinical visit/phone call). There was no recurrence of abdominal pain. The CT angiography showed complete remodeling and incomplete remodeling took place in 23 and 9 patients (69.7% and 27.3%), respectively. Two patients (6.1%) had mild in-stent stenosis. No stent rupture or migration was reported. This study demonstrated a satisfactory short-term result of stents implantation for SIDSMA, which indicated the endovascular treatment could be the first-line therapy for SIDSMA.

Endovascular aortic arch repair remains challenging due to the complicated anatomy and the involved vital branches. Off-label techniques emerged during the last decade, including endografts with parallel stents (known as Chimney, Periscope, Sandwich), surgeon-modified endografts, and various other reported techniques. fenestration of standard endografts represents another off-label endovascular means to maintain perfusion to aortic side branches located in the excluded area. Its principle is based on fenestration of an endograft following its deployment inside the vascular system. As data are emerging regarding fenestration, the aim of this article is to review recent progress of technical descriptions, and clinic results of fenestration from the available literature.

OBJECTIVE: To analyze the efficacy of integrated minimally invasive surgery for iliac vein compression syndrome with varicose veins of lower extremities. METHODS: From January 2017 to January 2018, 11 patients with iliac vein compression syndrome accompanied by varicose veins of lower extremities underwent left iliac vein stent implantation and radiofrequency thermal ablation of lower extremity veins in the First Affiliated Hospital of Zhejiang University School of Medicine. The left iliac vein stent was implanted through the puncture point approach of the main great saphenous vein, and then radiofrequency thermal ablation of the main saphenous vein was performed. Rivaroxaban and aspirin were administered from the day of surgery for 6 months and 12 months, respectively. After discharge, patients were followed up for more than 6 months. The lower extremity veins, iliac veins were reexamined by Doppler ultrasound or CT angiography at 2 weeks, 2 months and 6 months after surgery. RESULTS: The operations were successfully performed in 11 patients, and no complication was observed during the operation. The rates of soreness and swelling remission, pigmentation and skin quality improvement, and the iliac vein stent patency were 100%. No varicose vein recurrence, iliofemoral vein thrombosis and pulmonary embolism were found. CONCLUSIONS Integrated minimally invasive surgery is safe, effective and less invasive for iliac vein compression syndrome with varicose veins of lower extremities.

Objective    To investigate the preoperative localization of pulmonary glabrous nodules. Methods    A total of 192 patients admitted to General Hospital of  Northern Theater Command from April 2012 to September 2019 were selected for the study. There were 95 males and 97 females at an age of 56.47±11.79 years. All patients completed preoperative examination, and were divided into a positioning group (n=97) and a non-positioning group (n=95) according to whether the preoperative positioning was performed. And the surgical indicators between the two groups were compared. According to the substance of ground-glass opacity, they were divided into a pure ground-glass nodules group (n=23) and a mixed ground-glass nodules group (n=74) in the positioning group and a pure ground-glass nodules group (n=14) and a mixed ground-glass nodules group (n=81) in the non-positioning group . According to the size and distance of the nodules from the pleura and whether the nodules could be detected, the corresponding linear function was obtained. Results    The operative time of methylene blue localization group was shorter than that of the no localization group. In the scatter plot, the corresponding diameter and depth of the nodules and the corresponding coordinate points which can be explored were described. And linear regression was performed on all the coordinate points to obtain the linear function: depth=0.648×diameter–1.446 (mm). It can be used as an indication for the preoperative localization of pure ground-glass nodules in Da Vinci robotic surgery. Linear function: depth=0.559 5×diameter+0.56 (mm). It can be used as an indication of preoperative localization of mixed ground-glass nodules in Da Vinci robotic surgery. Conclusion    This equation can be used as a preoperative indication for clinical peripheral pulmonary ground-glass nodules.
