Outcome of Endovenous Laser Therapy for Saphenous Reflux and Varicose Veins: Medium-Term Results Assessed by Ultrasound Surveillance

ObjectiveTo assess the efficacy of endovenous laser therapy (EVLT) for treating saphenous reflux associated with varicose veins.DesignOut-patient treatment by EVLT with an 810 nm laser wavelength with results assessed by ultrasound surveillance.Patients361 patients who received EVLT for 509 incompetent saphenous veins over a five-year period.MethodsEVLT was used for proximal saphenous veins and ultrasound-guided sclerotherapy (UGS) for distal saphenous veins and tributaries. Control of reflux and occlusion or obliteration of the saphenous veins was assessed by serial ultrasound studies. Univariate Kaplan–Meier life table analysis showed cumulative primary and secondary success rates, and multivariate Cox regression analysis assessed covariates that could be associated with increased risk of ultrasound failure.ResultsLife table analysis showed primary success at four years in 76% (95% CI 56–87%) and secondary success at four years after further treatment of recurrence by UGS in 97% (95% CI 93–99%). Cox regression analysis showed a non-significant trend towards worse primary success in male patients and worse results for older patients and limbs with clinical CEAP categories C4–6. Cox regression showed significantly worse secondary success for limbs with clinical CEAP C4–6.ConclusionsEVLT effectively controls saphenous reflux particularly with ultrasound surveillance to detect early recurrence that can be treated by UGS. Modifications in technique may be required to improve the late primary success rate.     

Efficacy and safety of great saphenous vein sclerotherapy using standardised polidocanol foam (ESAF): a randomised controlled multicentre clinical trial.

AIM: To assess the safety and efficacy of sclerotherapy of the great saphenous vein (GSV) comparing standardised polidocanol foam to liquid polidocanol in a randomised controlled trial (RCT). METHODS: A multicentre randomised controlled clinical trial was carried out in which saphenous trunks were treated by sclerotherapy. 106 patients with primary varicose veins due to an incompetent GSV were treated with either standardised 3% polidocanol foam or 3% liquid polidocanol. The primary efficacy criterion was elimination of reflux (<0.5 sec) measured 3 cm below the sapheno-femoral junction (SFJ) by duplex ultrasonography 3 months after the last injection. RESULTS: A significantly greater number of patients were successfully treated by foam sclerotherapy resulting in 69% elimination of reflux compared to 27% patients treated with liquid sclerosant. The secondary endpoints of vein occlusion, reflux time, refilling time and patient satisfaction also improved significantly more in the foam group. The mean number of treatment sessions was 1.3 in the foam group compared to 1.6 in the liquid group. Differences between study centres occurred with a mean of 96% reflux elimination in 6 centres versus 39% in 4 other centres. Centres with a high response rate injected a higher mean volume (4.3 vs. 3.6 ml) in the first session in a vein with a smaller diameter (7.5 mm vs. 8.4 mm). No difference in adverse drug reactions was observed between treatment groups. CONCLUSIONS: Standardised 3% polidocanol foam is more efficient and equally safe compared to 3% liquid polidocanol for treatment of GSV. In comparison to other studies a relatively small volume was injected into relatively large veins.     

Saphenous ablation: sclerosant or sclerofoam?

During the last half of the 20th century, sclerotherapy as a major treatment of varicose veins came and went. At first, it was widely heralded as a substitute for surgery but after a prospective randomized study by Hobbs, interest in sclerotherapy waned. Just before the turn of the 21st century, Cabrera published his experience with foamed sclerosant in patients with great saphenous varices and arteriovenous malformations. Cabrera designed his treatment with the specific aim of obliterating the saphenous trunks. His technique consisted of filling the great saphenous vein in the thigh or the small saphenous vein in the calf with foamed sclerosant injected under ultrasound control. His initial report on long-term follow-up revealed that the results were at least comparable to surgery and perhaps somewhat better and his results have been confirmed by others. Investigations into treatment of small vein varices, including telangiectasias, has resulted in the finding that foam results in a 20% improved appearance compared to liquid sclerosant. The most popular sclerosants currently used as foams are polidocanol and sodium tetradecyl sulfate and of the many techniques used in making foams, the technique of Tessari has proven most popular. No randomized clinical trial comparing this technique to surgery has been published; however, the clinical series reports indicate that 80% to 90% of saphenous trunks remain occluded after 3 years when treated by foam sclerotherapy. Complications are seldom encountered but significant skin darkening and superficial thrombophlebitis are common. Temporary vision changes have occurred after foam and liquid sclerotherapy, with foam, these are always transient. Although the long-term efficacy of foamed sclerotherapy treatment is unlikely to be established for years, a number of phlebologists have taken up the practice because it has the advantage of not requiring general or regional anesthesia and takes much less time than equivalent surgical techniques.     

Prevalence of varicose veins and venous anatomy in patients without truncal saphenous reflux.

OBJECTIVES: To determine the prevalence and distribution of primary venous reflux in the lower limbs in patients without truncal saphenous reflux. DESIGN: Prospective cohort study. PATIENTS AND METHODS: One thousand and seven hundred and twelve patients with suspected venous disease were examined by duplex ultrasonography. Seven hundred and thirty-five patients had primary varicose veins with competent saphenous trunks. Limbs with truncal saphenous reflux, deep vein reflux or obstruction, previous injection sclerotherapy or vein surgery, arterial disease and inflammation of non-venous origin were excluded from further consideration. The CEAP classification system was used for clinical staging. Systematic duplex ultrasound examination was undertaken to assess the distribution of incompetent saphenous tributaries. RESULTS: The prevalence of primary reflux with competent saphenous trunks was 43%. Reflux of GSV calf tributaries was the most common. The majority of the limbs (96%) belonged to chronic venous disease classes C1 and C2 of the CEAP classification. CONCLUSIONS: Superficial venous reflux causing varicose veins in the presence competent saphenous trunks is very prevalent in this series in contrast to other studies, presumably reflecting differing patient populations. Our data clearly show that varicose veins may occur in any vein and do not depend on truncal saphenous incompetence. Careful duplex ultrasound evaluation allows the pattern of venous reflux to be established in this group of patient ensuring appropriate management of varices.     

Sclerotherapy of Reticular and Telangiectatic Veins of the Face, Hands, and Chest

BACKGROUND: Prominent tortuous veins of the face and hands may result from the process of aging and constitute a source of distress for many patients. Marked telangiectases of the chest and face are similarly distressing to some patients. OBJECTIVE: To determine the safety and efficacy of sclerotherapy for telangiectatic veins of the face and chest and varicose veins of the hands. METHODS: Twenty facial telangiectases and tortuous veins in 14 patients and 20 total facial sites were treated with sclerotherapy. Patients did not suffer from collagen vascular diseases, had no chronic illnesses, and were thoroughly informed of the strictly cosmetic nature of the procedure. A hyperosmolar sclerosant was used in 16 of 20 sites and the remaining 4 sites were treated with a detergent sclerosant (polidocanol 0.5-0.75%). The follow-up period ranged from 9 months to 15 years. Similarly the varicose veins of 14 hands in seven patients were treated with sclerotherapy using a detergent sclerosant [sodium tetradecyl sulfate (STS)] at various concentrations (1-3%). The follow-up period ranged from 1 to 6.5 years. Tortuous veins and telangiectases on the chest of three patients were treated with either STS 0.25-0.50% or polidocanol 0.75% with a follow-up of 2-9 years. RESULTS: Tortuous facial veins and telangiectases had a mean improvement of 70%, with 11 of 20 sites showing a 90-100% improvement. Hand varicosities had a mean improvement of 97.8%, and all sites showed a 90-100% resolution of varicosities. Finally, the tortuous veins and telangiectases of the chest improved by 50-100% with sclerotherapy. Only minimal to moderate telangiectatic matting was observed in two patients (one in the lateral canthal area and one near the treatment site of chest reticular veins). No ulceration or hyperpigmentation occurred long term in facial or hand veins. One patient developed an arterial ulceration on the left lateral breast. CONCLUSION: Sclerotherapy of varicose and telangiectatic veins of the face, hands, and chest can be safe and effective. Care must be given to sclerotherapy in the chest area, particularly the breast.     

Role of precapillary arteriovenous shunting in the pathogenesis of varicose veins and its therapeutic implications

The conventional pathogenesis of varicose veins and their subsequent development is essentially based on primary valvular insufficiency of the main saphenous trunk and incompetence of the perforating veins. In contrast, the concept of the pathogenesis of varicose veins presented in this review is based on the presence of arteriovenous (AV) shunting that occurs primarily in the venous tributaries and rarely in the main trunks of the saphenous system. Identification of arteriovenous communications (AVCs) with varicose veins has been documented by visual observation during surgery and especially by use of high-powered microscopes or magnifying lenses. The AVCs have been found consistently to originate subfascially and to terminate in tributaries extrafascially, thus bypassing the capillary network. By means of serial arteriography it was shown that in more than 80% of varicose veins there is premature venous opacification. By means of Doppler ultrasonography, it was demonstrated that AV shunting was present in 80% of the cases. A correlative study of these parameters has shown that the initial significant pathology in varicose veins is mostly confined to the tributaries, although at an advanced stage the main trunk may also be subsequently affected to a lesser degree. In terms of management, these data strongly imply that sclerotherapy or surgical treatment (ligation or excision) should be confined to the tributaries and that high saphenofemoral ligation and stripping should be avoided except in cases where evidence shows valvular involvement and incompetency of the latter. As a result, this study strongly suggests that one could most often spare the main trunk of the saphenous vein for eventual use as a vascular graft.     

Endovenous laser therapy and radiofrequency ablation of saphenous varicose veins

Radiofrequency ablation (RFA) and endovenous laser treatment (EVLT) are minimal invasive methods to treat saphenous varicose veins. The short- and mid-term results are excellent with an occlusion rate for RFA of almost 90% after 5 years and about 95% for EVLT after 2 years. Severe side effects are rare in both cases. Prospective randomised comparative studies are available for RFA and surgery showing comparable short-term results and superiority of RFA concerning short-term quality of life outcome. For laser treatment no prospective randomised comparative studies are available. Endovenous treatment is only a part of the complex treatment concept of varicose veins. Insufficient tributaries have to be treated in addition. The fact that the insufficient saphenous vein is treated without high ligation seems not to influence the short-term and mid-term recurrence rates. More prospective randomised comparative studies comparing endovenous treatment and surgery or foam sclerotherapy are necessary to decide which method is the best for which patient.     

低剂量免疫抑制剂治疗轻中症ANCA相关性肾血管炎的效果和肾脏预后分析

目的高剂量免疫抑制剂治疗导致的继发感染是ANCA相关性血管炎患者最常见的死亡原因，本研究旨在探索低剂量的免疫抑制剂治疗是否可以在减少轻中症ANCA相关性肾血管炎患者继发感染的同时达到有效缓解，并分析治疗早期继发感染是否会加速肾功能的恶化。 方法使用Fisher精确概率法比较初始糖皮质激素减量联合低频次静脉冲击环磷酰胺与标准方案的疗效及安全性差异；使用Kaplan-Meier生存曲线和Log-rank检验比较各因素影响下的肾脏存活率，将其中P<0.05的因素纳入多因素Cox风险回归模型以确定导致终末期肾病(ESRD)的危险因素，再使用受试者工作特征(ROC)曲线评价该危险因素的敏感性和特异性。 结果最终纳入58例患者，其中标准方案组35例、初始糖皮质激素减量组23例。纳入患者的平均年龄是(62.45±12.70)岁，平均基线血肌酐水平是251.35 μmol/L。24个月内有9例(15.52%)进展为ESRD(标准方案组7例，初始糖皮质激素减量组2例，P＝0.21)，治疗3个月后有10例发生继发感染(标准方案组9例，初始糖皮质激素减量组1例，P＝0.035)。多因素Cox风险回归模型显示：基线血肌酐(HR 1.01, 95%CI: 1.001~1.014, P＝0.014)、初治3个月内继发感染(HR 9.83, 95%CI: 2.14~45.27, P＝0.003)、接受治疗后持续性血尿超过6个月(HR 5.60, 95%CI: 1.36~23.18, P＝0.017)是ANCA相关性肾血管炎患者进展为ESRD的危险因素。 结论对轻中症ANCA相关性肾血管炎患者，初始糖皮质激素减量联合低频次静脉冲击环磷酰胺方案可明显降低继发感染率，且疗效不弱于标准方案。初治3个月内继发感染的患者早期进展为ESRD的风险更高。

Correlation of body weight and its change with albuminuria in physical examination population

Objective To study the effect of baseline weight and its change on new-onset albuminuria or increased urine albumin/creatinine ratio (ACR) in the physical examination population. Methods The subjects of this study were those who completed two or more physical examinations at the Physical Examination Center of Sichuan Provincial People's Hospital from September 1, 2013 to September 1, 2018. The general information and laboratory examination results at the first and last physical examinations were collected. According to body mass index (BMI), they were divided into normal BMI group and overweight/obese group. The differences in general clinical data and laboratory test results between the two groups were compared. The primary endpoint events were new-onset albuminuria or urine ACR increase≥30%. Stepwise multiple linear regression method was used to analyze the influencing factors for ACR increase, and Cox proportional hazard model method was used to analyze the impact of baseline weight and its change on new-onset albuminuria or ACR increase≥30%. Results A total of 1 761 physical examination subjects were included in this study. The follow-up time was (16.54±7.87) months. There were 59 patients with new-onset albuminuria, 30 patients with ACR increase≥30%, and 35 patients with albuminuria reversal. Multiple linear regression analysis showed that BMI was an independent influencing factor for ACR ( β=0.127, P＜0.001). Cox regression analysis showed that the older age (HR=1.041, 95%CI 1.018-1.064, P＜0.001), hypertension (HR=2.035, 95%CI 1.278-3.242, P=0.003), diabetes (HR=2.081, 95%CI 1.310-3.305, P=0.002) and hyperuricemia (HR=1.700, 95%CI 1.084-2.668, P=0.021) were independent influencing factors for new-onset albuminuria or ACR increase≥30%, while BMI (HR=1.053, 95%CI 0.975-1.137, P=0.191) and weight change rate (HR=1.030, 95%CI 0.972-1.092, P=0.322) were not independent influencing factors for endpoint events. Subgroup analysis indicated that overweight/obesity had interactions with age, hypertension, diabetes, and hyperuricemia, respectively (P for interaction＜0.05), and the effects of overweight/obesity on the pre-set primary endpoint events in each subgroup were basically consistent. There were interactions between weight gain and hypertension and diabetes (P for interaction＜0.05). Weight gain increased the risk of the primary endpoint events of women (HR=3.355, 95%CI 1.164-9.670, P=0.025), and the effects of overweight/obesity on the pre-set primary endpoint events of each subcomponent were basically the same (all P﹥0.05). The incidence of albuminuria reversal in the group with obvious weight loss was slightly higher than that in the group with obvious weight gain, but the difference was not statistically significant (P﹥0.05), which might be related to the small weight loss range (-6.08%±3.51%). Conclusions Overweight or obesity may increase the risk of albuminuria, and people with diabetes, hypertension, and hyperuricemia may be more likely to occur. Mild weight loss is not enough to reverse albuminuria.     

Stripping operation with sclerotherapy for primary varicose veins due to greater saphenous vein reflux: three-year results

The purpose of this study was to compare the recurrence-free rates of stripping with varicectomy and stripping with sclerotherapy for the treatment of primary varicose veins due to greater saphenous vein insufficiency. This is a multicenter retrospective analysis of 186 patients and 220 limbs treated for primary varicose veins due to greater saphenous vein reflux from January 1996 to December 1997. The difference between the two groups was evaluated by the Chi(2) test or t-test. The recurrence-free rates were estimated by the Kaplan-Meier life-table method. The mean follow-up period was 3.2 +/- 1.1 years. The clinical backgrounds of patients with varicectomy stripping and sclerotherapy stripping were not significantly different between the two groups. The overall recurrence-free rates at 1 and 3 years were 97.0% and 91.4%, respectively. The recurrence-free rates at 3 years were 93.5% for stripping with varicectomy and 88.6% for stripping with sclerotherapy. No statistical difference was found between the two groups. The recurrence rate after stripping with sclerotherapy was equivalent to that after stripping with varicectomy. Thus concurrent varicectomy can be replaced with sclerotherapy.     

Crossectomy and great saphenous vein stripping

Crossectomy and stripping have been the standard of care for primary great saphenous varicose veins since the high failure rates of sclerotherapy became apparent in the 1970s. As the specialty of venous surgery has evolved, a number of clinical trials have established the optimal methods of surgical treatment, and the clinical benefit of routine stripping. Long-term trials, however, have uncovered a high recurrence rate after varicose vein surgery that approaches 70% after 10 years. There is much debate about whether this is the result of the dilatation of existing tributaries in the groin or the growth of new veins as a result of angiogenesis that follows surgical treatment and healing (neovascularisation). The addition of barrier technology to current crossectomy has the potential to improve the results of surgery in the future. In the meanwhile, new techniques are evolving to obliterate the great saphenous vein, including endovenous laser, radiofrequency ablation and foam sclerotherapy. Randomised clinical trials are urgently required to compare these new treatments against standard surgery, and they will need to focus on whether the short-term gains in reduced convalescence and morbidity are balanced by durable long-term results.     

Contemporary analysis of the effect of marital status on survival in upper tract urothelial carcinoma patients treated with radical nephroureterectomy: A population-based study

PurposeUnmarried status is an established risk factor for worse cancer control outcomes in various malignancies. Moreover, several investigators observed worse outcomes in unmarried males, but not in females. This concept has not been tested in upper tract urothelial carcinoma and represents the topic of the study.MethodsWithin Surveillance, Epidemiology and End Results database (2004–2016), we identified 8833 non-metastatic upper tract urothelial carcinoma patients treated with radical nephroureterectomy (5208 males vs. 3625 females). Kaplan Meier plots and multivariable Cox regression models predicting overall mortality, other-cause mortality and cancer-specific mortality were used.ResultsOverall, 1323 males (25.4%) and 1986 females (54.8%) were unmarried. Except for lower rates of chemotherapy in unmarried males (15.6 vs. 19.6%, P = 0.001) and unmarried females (13.8 vs. 23.6%, P < 0.001), no clinically meaningful differences were recorded between males and females. In multivariable Cox regression models, unmarried status was an independent predictor of higher overall mortality in both males (Hazard ratio [HR]: 1.33, 95% confidence interval [CI]: 1.19–1.48, P < 0.001) and females (HR: 1.13, 95%CI: 1.00–1.27, P = 0.04), as well as of higher other-cause mortality in both males (HR: 1.53, 95%CI: 1.26–1.84,P < 0.001) and females (HR: 1.43, 95%CI: 1.15–1.78,P < 0.01). However, higher cancer-specific mortality was only recorded in unmarried males (HR: 1.24, 95%CI: 1.08–1.42, P < 0.01), but not in females (HR: 1.02, 95%CI: 0.89–1.17, P = 0.7).ConclusionUnmarried status is a marker of worse survival in both males and females and should be flagged as an important risk factor at diagnosis, in both sexes. In consequence, unmarried patients represent candidate for interventions aimed at decreasing the survival gap relative to married counterparts.     

Sclerotherapy of high venovenous blood reflux in patients with early varicose disease of the lower extremities

Results of diagnosis and treatment of 270 patients with varicose disease were analyzed. Based on duplex scanning two groups of patients were divided: group 1 consisted of 164 patients with low-intensity reflux, group 2 consisted of 106 patients with high-intensity reflux. Patients of group 1 were treated with ultrasound-assisted puncture sclerotherapy. In group 2 sclerosurgical procedures were used: sclerosant was injected into great saphenous vein trough catheter after crossectomy. For obliteration of varicose subcutaneous veins and perforants of shank the Irish technique was used. In group 1 recurrence of the disease was revealed in 9.1% patients, in group 2 -- in 9.4% patients.     

The study of cardiovascular disease and survival among maintenance hemodialysis patients

Objective To evaluate the associated factors about cardiovascular disease and survival among maintenance hemodialysis patients. Methods The newly diagnosed patients with ESRD in the 44th hospital of People's Liberation Army and Changzheng hospital during the period of 2008-2012 were analyzed retrospectively. The baseline variables and laboratory results were collected. Cardiovascular disease and survival were recorded. Logistic regression and multivariate COX regression were used to detect the relative factors. Results A total of 158 patients were included in the study. The mean age was 54.61±16.98. Cardiovascular complications were recorded in 40 cases. Heart and coronary artery disease were recorded 24 cases, strokes were recorded in 16 cases. Cox proportional hazards regression model showed thatage (HR=1.051, 95%CI:1.023-1.081), male (HR=6.025, 95%CI:2.571-14.121), increased neutrophile granulocyte(%) (HR=1.073, 95%CI:1.028-1.121), increased LDL (HR=1.562, 95%CI:1.058-2.305), high calcium concentration dialysate (HR=5.025, 95%CI:1.163-21.739) were risk factors for cardiovascular disease. Compared to conventional hemodialysis, in-center nocturnal hemodialysis was a protective factor (HR=0.288, 95%CI:0.090-0.924). In our study, 7 patients died. After adjusted to multiple variances, we found diabetes was a risk factor for survival (HR=15.385, 95%CI：1.692-145.851). Compared to conventional hemodialysis, hemodiafiltration may reduce the risk of CVD(HR=0.145, 95%CI:0.021-1.016, P=0.052). Conclusions To maintenance hemodialysis patients, age, male gender, the percent of neutrophile granulocyte, LDL, high calcium concentration dialysate are risk factors for CVD. In-center nocturnal hemodialysis reduces the risk ofCVD. Diabetes increase the risk of death, while hemodiafiltration may reduce the risk of death.     

The risk factors of mortality in peritoneal dialysis patients in different periods

Objective To explore the risk factors and characteristics in patients with peritoneal dialysis who died in different periods. Methods The clinical data of new peritoneal dialysis patients in the Department of Nephrology and Peritoneal Dialysis Center of the First Affiliated Hospital of Nanchang University from November 1, 2005 to February 28, 2017 was retrospectively analyzed. The patients were divided into two groups according to the time of death: those who died within one year and died after one year. The risk factors of mortality between the two groups were analyzed by Cox regression model. Results A total of 997 patients were enrolled and 244 patients died. There were 69 patients (28.3%) died within one year and 175 patients (71.7%) died after one year. Cardiovascular and cerebrovascular disease was the dominating reason of death in both groups, accounting for 59.4% (died within one year group) and 51.4% (died after one year group) respectively. Cox regression analysis showed that for died within one year group, old age (HR=1.035, 95%CI: 1.016-1.055, P＜0.001), low blood total calcium (HR=0.167, 95%CI: 0.053-0.529, P=0.002), low albumin (HR=0.899, 95%CI: 0.856-0.943, P＜0.001) and low apolipoprotein A1 (HR=0.274, 95%CI: 0.095-0.789, P=0.016) were risk factors associated with mortality. However, for died after one year group, old age (HR=1.053, 95%CI: 1.038-1.069, P＜0.001), combined with diabetes (HR=2.181, 95%CI: 1.445-3.291, P＜0.001) and hypertriglyceride (HR=1.204, 95%CI: 1.065-1.362, P=0.003) were risk factors associated with mortality. Conclusions The risk factors of mortality for peritoneal dialysis patients of different periods were not exactly the same. For died within one year patients, old age, low blood total calcium, low albumin and low apolipoprotein A1 were independent risk factors for mortality.However, for died after one year patients, old age, combined with diabetes, and high triglycerides were independent risk factors for mortality.     

The impact of age at the time of radiotherapy for localized prostate cancer on the development of second primary malignancies

Purpose

There is a known increased risk of second primary malignancy (SPM) in patients with prostate cancer (CaP) treated with radiotherapy (RT). It is unclear how age at diagnosis influences the risk of SPMs.

Ultrasound-guided foam sclerotherapy combined with sapheno-femoral ligation compared to surgical treatment of varicose veins: early results of a randomised controlled trial.

AIM: This study is a prospective randomised controlled trial comparing sapheno-femoral ligation, great saphenous stripping and multiple avulsions with sapheno-femoral ligation and ultrasound guided foam sclerotherapy to the saphenous vein. Primary end points were patient recovery period and quality of life and secondary end points frequency of complications on the two arms of the trial and the cost of the treatment. MATERIAL AND METHOD: Sixty patients with primary varicose veins due to GSV incompetence and suitable for day case surgery were randomly allocated to undergo ultrasound-guided sclerotherapy with sapheno-femoral ligation under local anaesthesia (n=30) or sapheno-femoral ligation, stripping and multiple avulsions under general anaesthesia (n=30). The study protocol included history, physical examination, assignment of CEAP class and assessment venous clinical severity score (VCSS), completion of the aberdeen vein questionnaire (AVQ) and colour duplex ultrasound. RESULTS: All treatments were completed as intended. Median time to return to normal activities was significantly reduced in the foam sclerotherapy group (2 days) compared to the surgical group (8 days) (p<0.001, Mann-Whitney). AVQ score was also significantly reduced at 3 months by 46% in the sclerotherapy group, and by 40% in the conventional surgery group (p<0.001, Wilcoxon). The time taken to complete treatment was shorter in the foam sclerotherapy plus SFJ ligation group: 45 vs. 85 min (p<0.001, Mann-Whitney). The overall cost of the procedure in the sclerotherapy group ( 672.97 pounds) was significantly less compared to conventional surgery ( 1120.64 pounds). At 3 weeks, there was no statistical difference in the complication rate between the two groups. At 3 months, median CEAP class dropped from four pre-operatively to one following treatment in both groups and the median VCSS score dropped from five to one in group one and from seven to three in group two (p<0.001, Wilcoxon test). In group one four patients (13%) had a recanalised vein which needed further sessions of foam sclerotherapy, resulting in a short-term closure rate of 87%. CONCLUSION: Ultrasound guided sclerotherapy combined with sapheno-femoral ligation was less expensive, involved a shorter treatment time and resulted in more rapid recovery compared to sapheno-femoral ligation, saphenous stripping and phlebectomies.

目的腹膜癌是一类原发或继发于腹膜表面的恶性肿瘤,肿瘤细胞减灭术(CRS)加腹腔热灌注化疗(HIPEC)是针对腹膜癌发展的一套综合治疗策略。本文旨在分析CRS+HIPEC治疗腹膜癌的疗效和安全性,并探讨影响其生存的预后因素。方法采用描述性病例系列研究方法,回顾性收集2004年1月至2020年1月武汉大学中南医院(330例)和首都医科大学附属北京世纪坛医院(1054例)腹膜肿瘤外科连续治疗的1384例腹膜癌患者的临床病理资料。分析本组患者CRS+HIPEC治疗情况(手术时间、器官切除数量、腹膜切除数量、吻合口数量、HIPEC方案等)、安全性[术中出血量、术后严重不良事件(SAE)及发生时间、治疗情况]、生存情况及影响生存的预后因素。SAE依照国际腹膜癌联盟不良事件定义进行分级,将Ⅲ~Ⅳ级不良事件定义为SAE。围手术期定义为CRS+HIPEC治疗日至术后30 d。OS定义为CRS+HIPEC手术当日至死亡或末次随访时间,采用Kaplan-Meier法进行生存结果描述,组间比较采用Log-rank检验。影响生存的独立预后因素则采用Cox比例风险回归模型单因素和多因素分析。结果全组患者中男529例(38.2%),中位年龄55(10~87)岁,中位体质指数为22.6 kg/m²。1384例腹膜癌患者中来源于胃癌164例(11.8%),结直肠癌287例(20.7%),腹膜假黏液瘤356例(25.7%),腹膜恶性间皮瘤90例(6.5%),卵巢癌、宫颈癌、子宫内膜癌及原发性腹膜癌等共计300例(21.7%),腹膜后肉瘤、肺癌、乳腺癌等少见来源肿瘤187例(13.5%)。本组患者中位手术时间595(90~1170)min,中位脏器切除数2(0~10)个,中位腹膜切除区域数4(0~9)个,中位腹膜癌指数(PCI)评分21(1~39)分,细胞减灭程度(CC)评分0~1分达61.9%(857/1384)。HIPEC方案:顺铂+多西他赛917例(66.3%)、顺铂+丝裂霉素183例(13.2%)、阿霉素+异环磷酰胺43例(3.1%)及其他方案240例(17.3%)。331例(23.9%)腹膜癌患者发生围手术期严重不良事件500例次,其中21例(1.5%)患者因治疗无效于围手术期内死亡,其余患者经积极治疗后痊愈。全组患者中位随访时间为8.6(0.3~182.7)个月,414例(29.9%)死亡,mOS为38.2个月(95%CI:30.6~45.8),1、3、5年生存率分别为73.5%、50.4%、39.3%。其中,胃癌腹膜转移、结直肠癌腹膜转移、腹膜假黏液瘤、恶性腹膜间皮瘤和妇科肿瘤及原发性腹膜癌患者mOS分别为11.3个月(95%CI:8.9~13.8)、18.1个月(95%CI:13.5~22.6)、59.7个月(95%CI:48.0~71.4)、19.5个月(95%CI:6.0~33.0)和51.7个月(95%CI:14.6~88.8),组间比较差异有统计学意义(P<0.001)。Cox单因素和多因素分析显示,原发肿瘤为胃癌(HR=4.639,95%CI:1.692~12.724)、结直肠癌(HR=4.292,95%CI:1.957~9.420)和恶性腹膜间皮瘤(HR=2.741,95%CI:1.162~6.466);卡氏功能状态(KPS)评分为60分(HR=4.606,95%CI:2.144~9.895)、70分(HR=3.434,95%CI:1.977~5.965);CC评分为1分(HR=2.683,95%CI:1.440~4.999)、2~3分(HR=3.661,95%CI:1.956~6.852)以及围手术期发生SAE(HR=2.588,95%CI:1.846~3.629)均是影响本组腹膜癌患者生存的独立危险因素,差异均有统计学意义(均P<0.05)。结论CRS+HIPEC是针对腹膜癌有效的整合治疗技术,可延长生存,围手术期安全性可接受。术前需要严格筛选病例,KPS评分<80分者应慎重选择接受CRS+HIPEC治疗;术中应在保证安全的前提下,努力达到满意细胞减灭程度;另还要应积极预防围手术期SAE以降低腹膜癌患者死亡风险。     

Clinical characteristics and treatment outcomes of relapsing,recurrent and repeat peritoneal dialysis-associated peritonitis: a multicenter study

Objective To explore the clinical characteristics and treatment outcomes of different types of peritoneal dialysis-associated peritonitis (PDAP). Methods The clinical data of PDAP patients admitted to the Second Hospital of Jilin University, Second Part of the First Hospital of Jilin University, Jilin Central Hospital and Jilin First Automobile Work General Hospital in Jilin province from 2013 to 2019 were reviewed. According to the type of PDAP, the patients were divided into relapsing group, recurrent group, repeat group and control group, and the baseline data, pathogens culture and treatment outcomes among the four groups were compared. Results A total of 542 patients with PDAP were enrolled in the study, including 43 cases in relapsing group, 32 cases in recurrent group, 27 cases in repeat group and 440 cases in control group. The median follow-up time was 30.5 (16.0, 50.0) months. The rate of Gram-positive bacteria in repeat group was higher than that of control group (70.37% vs 42.95%, P=0.030); the rate of fungi in recurrence group was higher than that of control group (21.88% vs 3.86%, P=0.006). Compared with control group, relapsing group had a lower cure rate (67.44% vs 83.64%, P=0.048) and a higher relapse rate (23.26% vs 2.27%, P=0.002), and recurrent group had a higher catheter removal rate (28.13% vs 8.18%, P=0.012). Multivariate logistic regression showed that recurrence was an independent risk factor for catheter removal (OR=5.137, 95%CI 2.105-12.539, P＜0.001). The technical failure rates in relapsing group and recurrent group were both higher than those in control group (41.86% vs 17.05%, P=0.002; 46.88% vs 17.05%, P=0.002). Multivariate Cox regression showed that relapse and recurrence were both independent risk factors for technical failure (HR=2.587, 95%CI 1.525-4.389, P＜0.001; HR=3.571, 95%CI 2.022-6.306, P＜0.001), and also were independent risk factors for composite endpoint (HR=1.565, 95%CI 1.045-2.344, P=0.030; HR=2.004, 95%CI 1.269-3.164, P=0.003). Conclusion Compared with common PDAP, the therapeutic effects and prognosis of relapsing and recurrent PDAP are worse.
