Objective To evaluate the prevention and treatment of prosthetic infections after tension free hernioplasty. Methods The clinical date of 12 prosthetic infections admitted from May 2005 to May 2008 were analyzed retrospectively. Patch was inserted under prefascial retromuscular site in 8 cases, between fascial edges in 2, Mesh plug and patch Lichentstein in one each. As for the material used there were flat knitted polypropylene in 7 cases, polytef in 1 case and composite prosthesis in 4 cases. Treatments were based on prothetic materials and levels infected. Infectious patchs were removed completely in 8 cases and partially removed in 2 cases, Open dress change with patchs left in situ in 2 cases. 3 cases in 10 cases of removed patchs were given immediate suturation with closed drainage. Results Infection was cured in all cases without mortality. There was no hemorrhage and injury of bladder during the procedures. No retention of urine, pain and other complications during postoperation. Change of dressing was made from 7 days to 6 months( median 2 weeks). Selected antibiotic was used from 3 to 7 days (average 4.5 days). All patients were followed up from 18 to 78 months (average 38.5 months) without hernia recurrence and infection. Conclusion It was most important to prevent infections after tension-free hernioplasty. Management should be individualized according to different type of patch used and the surgical procedure in hernia repair.

Objective To evaluate the effect of local resection for the tumor of Vater ampulla. Methods seventeen cases of Vater ampullary tumor were subjected to tumor local resection from November 1987 to December 1998, including 3 adenomas and 14 adenocarcinomas confirmed by pathology. Two methods of excision for the tumor were performed, including through duodenum to perform the tumor local resection in 16 cases, and through common bile duct in 1 case. Results Bile duct infection occurred in 3 cases. There was no death in this series. 12 of the 17 cases (70.6%) had been followed up for 4～61 months, median survival time was twelve months. In three benign cases ,one died with another disease 17 months postoperatively, two still alive well 38 and 7 months after operation respectively. In 14 malignancy, 9 cases (64.3%) had been followed up. Of the 9 cases, 6(66.7%) alived ≥ 12 months, 4 (44.4%) 24 months, two(22.2%) 60 months. Conclusions Local resection of the Vater ampulla tumor has advantages, such as small damage ,less bloodlass, quick recovery and less interference of the body, but it must be performed by rich experienced surgeons. It is suitable for patients with a small benign tumor, or in the high risk patients whose carcinoma showed no invasion or metastasis, and it also can be performed in patients such as those with atypical hyperplasia and suspious malignant tumor.

Objective To investigate the clinical efficacy of endovascular treatment for iliac vein compression syndrome (IVCS) in 112 cases. Methods From September 2011 to June 2015, 112 cases of IVCS (Cockett syndrome) were treated in our hospital with endovascular methods .The case numbers of different CEAP ( clinical etiological anatomical pathophysical ) classifications were C2 (45 cases), C3 (23 cases), C4 (19 cases), C5 (11 cases) and C6 (14 cases).All the cases were diagnosed by venography .The operations started from puncturing the ipsilateral veins .The stenotic degree and compressed intensity of iliac vein were evaluated by the minimum diameter with low pressure balloon .And then a stent was placed into after percutaneous transluminal angioplasty ( PTA) when residual stenosis was more than 50%.The occlusive segment was dilated by 8 mm diameter balloon firstly , and catheter directed thrombolysis treatment was applied if thrombus was detected .The PTA and stenting were performed when the thrombus was completely removed .The improvement of clinical symptoms was observed after operation and the patients were followed up by ultrasound and venograghy . Results Nine cases were given PTA only , and the other 103 cases underwent stent placement . Postoperative venography showed collateral vessels were disappeared in 22 cases, obviously decreased in 56 cases and mildly decreased in 34 cases.The average difference of swelling leg ’s circle was diminished from (2.56 ±0.88) cm pre-operation to (0.93 ±0.71) cm post-operation, while the average area of skin ulcer was diminished from (6.34 ±3.78) cm2 pre-operation to (2.13 ±1.88) cm2 post-operation, all of which were statistically significant (t =20.24 and 7.19,P=0.000).A total of 86 cases were successfully followed up during a period from 2 months to 45 months (average, 19.2 months).The patency rate of treated iliac vein 12 months after operation was 76.2%in the PTA group, and in the PTA with stenting group was 96.7%, 88.6%, and 86.1%, respectively, at 12, 24, and 36 months after operation, in which a statistical significance was detected (log-rank χ2 =30.32, P=0.000).The patency rate in diameter ≥16 mm group was 95.2%and 95.2%, respectively, at 12 and 24 months after operation, while in diameter <16 mm group was 97.0%and 93.3%, respectively, in which no statistical significance was detected (log-rankχ2 =0.39, P=0.532).Thrombotic complication was found in 2 cases during the follow-up period , including 1 case of iliac vein thrombosis at 1 month and 1 case of thrombus in contralateral leg 8 months later .According to the results of venography in 78 cases at 12 months after operation , restenosis was found in 5 out of 6 cases in the PTA group, and the patency rate in the stent placement group was 95.8%(69/72).No stent migration was found . Conclusion Comfortable clinical results were obtained after endovascular therapy for iliac vein compression syndrome , and the application of stenting could increase the middle and long term patency rate of treated vessels .

Objective To assess the efficacy and safety of interventional combine with surgical therapy of symptomatic portal vein thrombosis (PVT). Methods Seven patients with PVT were treated by surgical thrombectomy, regional medical thrombolysis, and angioplasty or stenting. Resection of part of the small intestine was performed in 2 cases due to enteric necrosis and in 1 case because of enteric stenosis. Results The procedure was successful in all the 7 patients. The preoperative symptoms (abdominal pain, distention, and ascites) were alleviated apparently. Follow-up observations for 3~24 months (mean, 16 months) showed no death. No alimentary tract hemorrhage occurred. Re-examinations with Doppler ultrasonography revealed patent blood flow in the portal vein. Conclusions Interventional combined with surgical therapy is safe and effective in the treatment of symptomatic portal venous thrombosis.
