Editor's Choice - Short Term Cost Effectiveness of Radiofrequency Ablation and High Ligation and Stripping for Great Saphenous Vein Incompetence.

OBJECTIVE: Superficial venous incompetence (SVI) is a common disease that causes significant quality of life (QoL) impairment. There is a need for more health economic evaluations of SVI treatment. The aim of this study was to perform a cost effectiveness analysis in patients with great saphenous vein (GSV) incompetence comparing radiofrequency ablation (RFA), high ligation and stripping (HL/S), and no treatment or conservative treatment with one year follow up. METHODS: Randomised controlled trial economic analysis from an ongoing trial; 143 patients (156 limbs) with GSV incompetence (CEAP clinical class 2 - 6) were included. Treatment was performed with RFA or HL/S. Follow up was performed up to one year using duplex ultrasound, revised venous clinical severity score (r-VCSS), Aberdeen Varicose Vein Questionnaire (AVVQ), and EuroQol-5D-3L (EQ-5D-3L). RESULTS: Seventy-eight limbs were treated with RFA and HL/S respectively. No treatment or conservative treatment was assumed to have zero in treatment cost and no treatment benefit. In the RFA group, one limb had reflux in the GSV after one month and three limbs after one year. In HL/S, two limbs had remaining reflux in the treated area at one month and one year. Both disease severity (r-VCSS, p = .004) and QoL (AVVQ, p = .021 and EQ-5D-3L, p = .028) were significantly improved over time. The QALY gain was 0.21 for RFA and 0.17 for HL/S. The cost per patient was calculated as €1 292 for RFA and €2 303 for HL/S. The cost per QALY (compared with no treatment or conservative treatment) was €6 155 for RFA and €13 549 for HL/S. With added cost for days absent from work the cost per QALY was €7 358 for RFA and €24 197 for HL/S. The cost per QALY for both methods was well below the threshold suggested by Swedish National Board of Health. CONCLUSION: RFA is more cost effective than HL/S and no treatment or conservative treatment at one year follow up.

Interventions for great saphenous vein insufficiency: A systematic review and network meta-analysis.

BACKGROUND: Great saphenous vein insufficiency (GSVI) adversely affects the quality of life of affected individuals. Minimally invasive endo-venous ablation techniques have emerged as effective and safe treatments, despite the longstanding use of surgical interventions. We aim in our study to evaluate all the available interventions in the literature, either endo-venous or conventional approaches for the treatment of GSVI. METHODS: A thorough search was performed across four electronic databases to identify relevant studies. A frequentist network meta-analysis (NWM) was executed on the combined data to derive network estimates pertaining to the outcomes of concern. Risk ratios (RRs) were employed as the effect size metric for binary outcomes, while mean differences (MDs) were utilized for continuous outcomes, each reported with a 95% confidence interval. The qualitative review was conducted employing the Cochrane risk of bias assessment tool 1. RESULTS: Our NWM included 75 studies encompassing 12,196 patients. Regarding technical success rate within the first 5 years after treatment, Endo-venous Laser Ablation (EVLA) with High Ligation and Stripping (HL/S), EVLA alone, Cyanoacrylate Adhesive Injection, cryostripping, HL/S and Radiofrequency Ablation (RFA) were significantly better than Ultrasound-Guided Foam Sclerotherapy and F-care. Also, invagination stripping was inferior to all interventions. Conservative Hemodynamic Cure for Venous Insufficiency and Varicose Veins (CHIVA) demonstrated a significantly lower recurrence rate with a RR of 0.35 [0.15; 0.79] compared to RFA, but RFA was more effective in recurrence prevention than HL/S and Mechanochemical Ablation (MOCA), with a RR of 0.63 [0.41; 0.97] and 0.18 [0.03; 0.95], respectively. Endo-venous Steam Ablation (EVSA) emerged as the most effective in reducing post-intervention pain, showing a MD of -2.73 [-3.72; -1.74] compared to HL/S. In Aberdeen Varicose Vein Questionnaire outcome, our analysis favored MOCA over most studied interventions, with an MD of -6.88 [-12.43; -1.32] compared to HL/S. Safety outcomes did not significantly differ among interventions. CONCLUSION: Our findings revealed significant variations in the technical success rates, recurrence rates, and post-intervention pain levels among different interventions. CHIVA exhibited enhanced performance in terms of lower recurrence rates, while EVSA emerged as a promising choice for mitigating post-intervention pain. Additionally, our analysis underscored the significance of patient-reported outcomes, with MOCA consistently yielding favorable results in terms of enhancing quality of life and expediting the return to regular activities.

Level of Inferior Mesenteric Artery Ligation in Sigmoid Colon and Rectal Cancer Surgery: Analysis of Apical Lymph Node Metastasis and Recurrence.

INTRODUCTION: Whether high or low ligation of the inferior mesenteric artery (IMA) is optimal for treating sigmoid colon and rectal cancers is controversial. The present study aimed to compare outcomes of high and low ligation of the IMA and determine the adequate extent of IMA lymph node dissection. METHODS: Subjects were 455 consecutive stage I-III colorectal cancer patients who underwent curative surgery between 2011 and 2019. We assessed the association between the level of IMA ligation and overall survival and recurrence-free survival (RFS) by propensity score matching analysis. Clinicopathological features of IMA lymph node metastasis and recurrence patterns were analyzed. RESULTS: After propensity score matching, the low ligation group had a significantly worse prognosis than that of the high ligation group for RFS (p = 0.039). Positive IMA lymph nodes were associated with pathological T3 or T4 stage and N2 stage. IMA lymph node recurrences in the high ligation group occurred at the superior left side of the IMA root. In contrast, all recurrences in the low ligation group occurred at the left colic artery bifurcation. CONCLUSION: High ligation of IMA is oncologically safe. However, even with high ligation, care must be taken to ensure adequate lymph node dissection.

Single-site laparoscopic high ligation of the extraperitoneal hernia sac with an epidural needle for incarcerated ovarian hernia in infants.

BACKGROUND: The purpose of this study was to evaluate the safety and efficacy of single-site laparoscopic extraperitoneal hernia sac ligation with an epidural needle for incarcerated ovarian hernias in infants and young children. METHODS: The clinical data of 38 infants with incarcerated ovarian hernias who underwent single-site laparoscopic extradural needle extraperitoneal hernia sac ligation from January 2015 to January 2018 were retrospectively analysed. RESULTS: All procedures were successfully performed using laparoscopy with no need for conversion to open surgery. The time of hospital stay was 1.30 ± 0.39 days. During hospitalization and follow-up, there were no complications, such as intestinal or bladder injury, abdominal wall vascular injury, ovarian atrophy, hernia recurrence or contralateral indirect hernia. However, three patients experienced complications, including two cases of poor healing of the umbilical incision and one case of suture granuloma. CONCLUSIONS: Single-site laparoscopic high ligation of the extraperitoneal hernia sac with an epidural needle is a safe and feasible method for the treatment of incarcerated ovarian hernias in infants and young children. It has the advantages of minimal trauma, no scarring and good cosmetic effects.

High Versus Low Ligation of the Inferior Mesenteric Artery in Colorectal Cancer Surgery: A Systematic Review and Meta-Analysis.

Background and Objectives: This study aimed to compare the effects of high ligation (HL) versus low ligation (LL) in colorectal cancer surgery. Materials and Methods: We performed a comprehensive search using multiple databases (trial registries and ClinicalTrials.gov), other sources of grey literature, and conference proceedings, with no restrictions on the language or publication status, up until 10 March 2021. We included all parallel-group randomized controlled trials (RCTs) and considered cluster RCTs for inclusion. The risk of bias domains were "low risk," "high risk," or "unclear risk." We performed statistical analyses using a random-effects model and interpreted the results according to the Cochrane Handbook for Systematic Reviews of Interventions. We used the GRADE guidelines to rate the certainty of evidence (CoE) of the randomized controlled trials. Results: We found 12 studies (24 articles) from our search. We were very uncertain about the effects of HL on overall mortality, disease recurrence, cancer-specific mortality, postoperative mortality, and anastomotic leakage (very low CoE). There may be little to no difference between HL and LL in postoperative complications (low CoE). For short-term follow-up (within 6 months), HL may reduce defecatory function (constipation; low CoE). While HL and LL may have similar effects on sexual function in men, HL may reduce female sexual function compared with LL (low CoE). For long-term follow-up (beyond 6 months), HL may reduce defecatory function (constipation; low CoE). There were discrepancies in the effects regarding urinary dysfunction according to which questionnaire was used in the studies. HL may reduce male and female sexual function (low CoE). Conclusions: We are very uncertain about the effects of HL on survival outcomes, and there is no difference in the incidence of postoperative complications between HL and LL. More rigorous RCTs are necessary to evaluate the effect of HL and LL on functional outcomes.

High ligation of the inferior mesenteric artery and anastomotic leakage in anterior resection for rectal cancer: a systematic review and meta-analysis of randomized controlled trial studies.

AIM: Surgeons have concerns whether high ligation (HL) of the inferior mesenteric artery (IMA) increases the incidence of anastomotic leakage (AL). This meta-analysis aimed to evaluate the influence of HL of the IMA on AL compared with low ligation (LL). METHODS: PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov databases were searched. Randomized controlled trial studies that compared HL with LL of the IMA in anterior resection for rectal cancer and reported AL outcomes were eligible for inclusion. The odds ratios and mean differences were analysed by a random-effects model. Trial sequential analysis was performed to minimize the risk of random errors. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of evidence for outcomes. RESULTS: Of the 531 records screened, five randomized controlled trials with 779 patients were selected for analysis. The pooled incidence of AL was 12.1% (95% Cl 7.77-18.26) in the HL group and 9.7% (95% Cl 5.79-15.82) in the LL group (OR 1.20, 95% CI 0.77-1.87, P = 0.42). In trial sequential analysis, the cumulative Z-score curve exceeded the futility boundary, although the required information size of 1060 had not been reached. The quality of evidence was judged to be high according to the GRADE approach. CONCLUSIONS: This meta-analysis shows that HL of the IMA does not increase the incidence of AL in anterior resection for rectal cancer.

Pathological features of lymph nodes around inferior mesenteric artery in rectal cancer: a retrospective study.

OBJECTIVE: This study aimed to explore the pathological characteristics of lymph nodes around inferior mesenteric artery in rectal cancer and its risk factors and its impact on tumor staging. METHODS: 485 rectal cancer patients underwent proctectomy surgery were collected in this study. Clinical features of patients, including gender, age, BMI, tumor size, pathological type, differentiation, nerve invasion, lymph nodes, tumor marker, and pathological examinations, were analyzed. RESULTS: A total of 485 cases were included in this study. There were 29 cases with IMA-LN metastasis; the metastasis rate was 5.98% (29/485). Positive IMA-LNs were associated with distance from anal verge, CEA, pathological type, differentiation, nerve invasion, T stage, and N stage. Multivariate analysis showed that distance from anal verge, CEA level, differentiation, and T stage were independent risk factors for positive IMA-LNs. CONCLUSION: Distance from anal verge, CEA level, differentiation, and T stage were independent risk factors for positive IMA-LNs. No skip metastasis occurred in IMA-LNs. We should choose the appropriate surgical methods to achieve better oncological results and reduce the incidence of postoperative complications.

Association of high ligation versus low ligation of the inferior mesenteric artery on anastomotic leak, postoperative complications, and mortality after minimally invasive surgery for distal sigmoid and rectal cancer.

BACKGROUND: In the treatment of distal sigmoid and rectal cancer, the appropriate level for the ligation of the inferior mesenteric artery (IMA) remains unresolved. High ligation divides the IMA proximally at its origin, and low ligation ligates the IMA distal to the origin of left colic artery. We assessed the association of level of ligation in scheduled minimally invasive resection of sigmoid and rectal cancers on anastomotic leak, postoperative complications, and death within 30 days. METHODS: We identified all patients with primary sigmoid and rectal cancer treated with scheduled minimally invasive resection and primary anastomosis between January 2002 and June 2018 using linked institutional and National Surgical Quality Improvement Program databases. We assessed the association of level of ligation with each outcome by fitting individual univariable and multivariable logistic regression models, adjusting for surgical approach, tumor location, neoadjuvant chemoradiotherapy, and Charlson comorbidity index. RESULTS: We included 158 patients treated with high ligation and 123 patients treated with low ligation. Overall, 12 patients had an anastomotic leak requiring intervention within 30 days: 5 in the high ligation group (3.2%, 95% CI 1.4-7.2%) and 7 in the low ligation group (5.7%, 95% CI 2.8-11.3%). There was no association between the level of ligation and anastomotic leak (unadjusted OR 1.85, 95% CI 0.58-6.38; adjusted OR 0.63, 95% CI 0.16-2.55). Similarly, there was no association between the level of ligation and reoperation for anastomotic leak (OR 1.29, 95% CI 0.15-10.9), major complications (Clavien-Dindo III-V; OR 2.22, 95% CI 0.90-5.77), minor complications (Clavien-Dindo I-II; OR 1.51, 95% CI 0.88-2.60), and all complications (OR 1.58, 95% CI 0.94-2.67). No deaths occurred in either group. CONCLUSIONS: There was no association of level of ligation of the IMA with anastomotic leak, postoperative complications as a composite, or death. The choice of high or low ligation of the IMA should be made based on technical factors such as length for the creation of a tension-free anastomosis.

Outcomes of high versus low ligation of the inferior mesenteric artery with lymph node dissection for distal sigmoid colon or rectal cancer.

PURPOSE: We compared the complication rates and oncologic and functional outcomes of high versus low ligation of the inferior mesenteric artery (IMA). METHODS: We reviewed data retrospectively from 776 patients, divided into high and low IMA ligation groups. Low ligation was performed with lymph node dissection around the IMA root. Postoperative complications and oncologic and functional outcomes were analyzed. RESULTS: There were 613 patients in the high ligation group and 163 patients in the low ligation group. Most clinicopathological variables were similar. There were no significant differences in complication rates (25.1% vs. 28.8%; p = 0.336), anastomotic leakage (2.8% vs. 2.5%; p = 1.000), colonic ischemia (2.8% vs. 1.2%; p = 0.393), 5-year overall survival (79.6% vs. 81.3%; p = 0.137) or 5-year relapse-free survival (77.4% vs. 73.3%; p = 0.973) between the groups. In terms of functional outcomes, both techniques were equivalent. The International Prostate Symptom Score and Fecal Incontinence Severity Index were significantly better in the low ligation group 12 months postoperatively than 3 months postoperatively. CONCLUSIONS: The oncologic and functional outcomes, as well as postoperative complications, after low ligation of the IMA with lymph node dissection are not significantly different from those after high ligation of the IMA.

Endovenous (minimally invasive) procedures for treatment of varicose veins : The gentle and effective alternative to high ligation and stripping operations.

Thermal ablation of saphenous vein varicosis has developed into a standard procedure for treatment of varicose veins. The clinical success of the endovenous thermal procedure is comparable to high ligation and stripping operations and a significant difference between these groups could not be detected in long-term analyses. The only difference is in the genesis of saphenofemoral recurrence detected by duplex ultrasound: neoangiogenesis occurs after high ligation and stripping operation and after endovenous ablation of the great saphenous vein a recurrence occurs predominantly via a residual anterior accessory saphenous vein (AASV). Reduction of costs by an increase in endovenous procedures carried out in an outpatient setting in comparison to stripping operations, which are still frequently carried out in Germany (in comparison to other countries) as an inpatient procedure, have meanwhile been confirmed. An endovenous crossectomy (i.e., high ligation) should be strived for. Nonthermal endoluminal catheter procedures are predominantly reserved for treatment of the short saphenous vein.

Comparison of endovenous laser treatment and high ligation in treatment of limb varicosity: A meta-analysis.

To assess the efficacy and safety of endovenous laser treatment (EVLT) and high ligation (HL) for limb varicosity using meta-analysis. Multiple databases including PubMed, Springer, Excerpta Medica Database, Ovid Technologies, and China Journal Full-text database were searched for relevant studies in English or Chinese, and full-text articles were used to compare EVLT and HL for limb varicosity. Review Manager 5.0 was used to estimate the effects of the results among eligible articles. Forest plots, sensitivity analysis, and bias analysis of the included articles were also conducted. Initial screening yielded 1031 studies, 11 randomised controlled trials involving 1145 limb varicosity patients met the inclusion criteria in this study. The results of the heterogeneity test suggested that intraoperative blood loss mean difference (MD) = -6.31[-9.03, -3.60], P < 0.00001), operative time (MD) = -39.76[-42.27, -37.24], P < 0.00001), rate of complications (odds ratio [OR] = 0.37[0.22, 0.61], P < 0.0001), and recurrence (OR = 0.28[0.16, 0.49], P < 0.0001) were significantly different. Although both EVLT and HL have their own merits and demerits, EVLT is a more effective and safe method to treat limb varicosity.

High ligation of the inferior mesenteric artery during sigmoid colon and rectal cancer surgery increases the risk of anastomotic leakage: a meta-analysis.

BACKGROUND: The ideal level of ligation of the inferior mesenteric artery (IMA) during curative resection of sigmoid colon and rectal cancer is still controversial. The aim of this meta-analysis was to examine the impact of high ligation and low ligation of the IMA on anastomotic leakage, overall morbidity, postoperative mortality, and oncological outcomes in patients undergoing surgery for sigmoid colon and rectal cancer. METHODS: PubMed, EMBASE, Web of Science, and BioMed Central databases were searched to identify relevant articles published from May 1953 to March 2018. A total of 18 articles (14 non-randomized studies and 4 randomized clinical trials) were identified. Review Manager 5.3 software was used for analysis of data. The pooled odds ratio (OR) and weighted mean difference (WMD), with 95% CI, were calculated using either the fixed effects model or random effects model. RESULTS: Of the 5917 patients included in this meta-analysis, 3652 patients underwent low ligation of the IMA and 2265 patients underwent high ligation of the IMA. Anastomotic leakage rate was 9.8% in high ligation patients vs. 7.0% in low ligation patients; the risk of anastomotic leakage was significantly higher in high ligation patients (OR = 1.33; 95% CI 1.10-1.62; P = 0.004). What is more, overall morbidity was also significantly higher in high ligation patients (OR = 1.39; 95% CI, 1.05-1.68; P = 0.05). Postoperative mortality, number of harvested lymph nodes, overall recurrence rate, and 5-year survival rate did not differ significantly between the two groups. CONCLUSION: Low ligation of the IMA during curative resection of sigmoid colon and rectal cancer appears to be associated with lower risk of anastomotic leakage and overall morbidity. However, there was no significant advantage of low ligation over high ligation of IMA in terms of postoperative mortality, the number of harvested lymph nodes, overall recurrence rate, or 5-year survival rate.

Treatment of routine adolescent inguinal hernia vastly differs between pediatric surgeons and general surgeons.

BACKGROUND: Surgical treatment of inguinal hernias in adolescents is controversial as these patients do not fit into the traditional pediatric and adult populations. We aimed to compare the preferences of adult general surgeons and pediatric surgeons in managing adolescents by conducting a survey through social media. METHODS: A poll was posted on the International Hernia Collaboration Group Facebook page as well as the Facebook page for the authoring pediatric surgeon. The poll gave scenarios of a 16-year-old male with an inguinal hernia and asked surgeons to select one of five listed procedures to repair the hernia: high ligation (open or laparoscopic), mesh repair (open or laparoscopic) or open muscle repair. The four scenarios differed in the diameter of the internal ring (1 vs. 4 cm) and the BMI of the patient (20 vs. 35). Fisher's exact test was implemented for statistical analysis. RESULTS: In total, 43 (67 %) adult surgeons and 21 (33 %) pediatric surgeons responded. In the routine adolescent (normal BMI, small defect), 65 % of adult surgeons chose adult-type repairs (mesh or muscle repairs) whereas 86 % of pediatric surgeons chose pediatric-type repairs (high ligation). When the size of the defect increased, 100 % of adult surgeons and 81 % of pediatric surgeons selected an adult-type repair, suggesting agreement. When the patient was obese, there was a tendency to prefer laparoscopy. In all patient scenarios, the answers were significantly different between pediatric and adult surgeons (p < 0.05). CONCLUSION: For the same routine adolescent inguinal hernia, pediatric surgeons and adult general surgeons choose a different procedure. This finding suggests that further study is needed to determine the optimal treatment for inguinal hernias in adolescents, as the type of practitioner to whom the patient is referred, rather than the disease process itself, currently dictates treatment.

[Laparoscopic extraperitoneal high ligation of the spermatic vein for the treatment of varicocele].

OBJECTIVE: To investigate the effect of laparoscopic extraperitoneal (LSEP) high ligation of the spermatic vein in the treatment of varicocele. METHODS: We retrospectively analyzed the clinical data about 80 cases of varieocele, 48 treated by LSEP and the other 32 by laparoscopic transabdominal retroperitoneal (LSTR) high ligation of the spermatic vein. We recorded the semen parameters before and at 1, 3 and 6 months after surgery, intraoperative blood loss, operation time, postoperative complications, time of gastrointestinal function recovery and rate of pregnancy, followed by comparison of the data obtained between the two groups of patients. RESULTS: Semen parameters were remarkably improved in both the LSEP and LSTR groups of patients postoperatively as compared with the baseline (P <0.05), but with no statistically significant difference at different postoperative months (P >0.05). The intraoperative blood loss was less in the LSEP than in the LSTR group (ï¼»8.3 ± 5.2ï¼½ vs ï¼»9.1 ± 6.1ï¼½ ml, P >0.05), the operation time was shorter in the former than in the latter (ï¼»38.27 ± 9.23ï¼½ vs ï¼»43.46 ± 11.72ï¼½ min, P >0.05), and so was the time of gastrointestinal function recovery (ï¼»1.27 ± 0.26ï¼½ vs ï¼»2.43 ± 0.41ï¼½ d, P <0.05). No statistically significant differences were observed between the two groups during the 6- to 18-month follow-up in the rates of postoperative subcutaneous hematoma, scrotal and subcutaneous emphysema, recurrence, or pregnancy (P >0.05). CONCLUSIONS: Laparoscopic extraperitoneal high ligation of the spermatic vein is safe and effective and has the advantage of quick recovery in the treatment of varicocele.

Iatrogenic superior mesenteric vein injury: the perils of high ligation.

PURPOSE: The purpose of this review is to highlight the perils and pitfalls associated with high vascular ligation during right colectomies for adenocarcinoma and to identify the various mechanisms of injury to the superior mesenteric vein (SMV) and its tributaries. METHODS: This is a retrospective chart review of 304 right colectomies (159 open and 145 laparoscopic) performed over a period of 10 years (1 June 2006-31 May 2016) for right-sided colonic adenocarcinoma in an academic medical center. RESULTS: During a 10-year study period, we encountered five cases in which significant damage to the SMV and its tributaries occurred. This accounts for a total of 1.6 % of all right colectomies performed for colonic adenocarcinoma. CONCLUSIONS: Iatrogenic superior mesenteric vein injury is a rare, severe, and underreported complication of both open and laparoscopic right colectomy for colonic adenocarcinoma. We identified several mechanisms of injury such as anatomic misperception, excessive traction and pulling on the venous system, extensive tumor involvement of the mesentery, and uncontrolled suturing attempts at hemostasis. We believe that increased awareness of this complication with profound understanding of vascular anatomy and the different mechanisms of injury will allow surgeons to avoid this often devastating complication.

Clinical results of endovenous LASER ablation (EVLA) using low linear endovenous energy density (LEED) combined with high ligation for great saphenous varicose veins.

PURPOSE: This study was designed to analyze the efficacy and complications in endovenous LASER ablation (EVLA) with 1470 nm diode lasers using low linear endovenous energy density (LEED) combined with high ligation for varicose veins of the great saphenous vein (GSV). METHODS: One hundred and sixteen limbs of 102 patients were analyzed using 6 W with 2 mm/s constant pullback speed delivered by 30 J/cm LEED. The SFJ was ligated with a small inguinal incision. The complications and status of the GSV were checked at 1 and 6 months postoperatively. RESULTS: The occlusion rates for the GSV were 98 (84.5 %) at 1 month and 116 (100 %) at 6 months, postoperatively. The rate of partial occlusion was higher in males than in females (p = 0.004). There were 2 DVT, 27 feelings of the cord (23.3 %), and 36 numbness at the knee area (31.0 %) at 1 month, and 3 feelings of the cord (3.4 %) and 6 numbness of the knee (8.6 %) at 6 months postoperatively. The diameter and depth of the GSV did not affect the rates of feeling of the cord or numbness (p = 0.728, 0.208, 0.247, 0.884, respectively). CONCLUSION: EVLA with a 1470-nm diode laser using low LEED combined with high ligation for the GSV has lower complication rates and higher occlusion rates of GSV.

Same Site Recurrence is More Frequent After Endovenous Laser Ablation Compared with High Ligation and Stripping of the Great Saphenous Vein: 5 year Results of a Randomized Clinical Trial (RELACS Study).

OBJECTIVE: To compare the long-term clinical efficacy of endovenous laser ablation (EVLA) with high ligation and stripping (HLS) as standard treatment for great saphenous vein (GSV) incompetence. DESIGN: Investigator initiated two centre randomized controlled trial with 5 year follow up. MATERIALS AND METHODS: Interventions were performed on ambulatory and hospitalized patients at two vein centres, a university dermatology department (EVLA) and a specialized vein clinic (HLS). Four hundred patients suffering from GSV incompetence were assigned to EVLA or HLS of the GSV. One hundred and eighty five and 161 patients (=limbs), respectively, were treated per protocol. Main outcome measures were clinically recurrent varicose veins after surgery (REVAS classification, primary study objective), Duplex detected saphenofemoral recurrence, clinical venous severity scoring (Homburg Varicose Vein Severity Score), quality of life (Chronic Venous Insufficiency Questionnaire 2), side effects, and patient satisfaction 5 years after treatment. RESULTS: Two hundred and eighty one legs (81% of the study population) were evaluated with a median follow up of 60.4 (EVLA) and 60.7 months (HLS). Overall, REVAS was similarly observed in both groups: 45% (EVLA) and 54% (HLS), p = .152. Patients of the EVLA group showed significantly more clinical recurrences in the operated region (REVAS: same site): 18% vs. 5%, p = .002. In contrast, more different site recurrences were observed in the HLS group: 50% vs. 31%, p = .002. Duplex detected saphenofemoral refluxes occurred more frequently after EVLA: 28% vs. 5%, p < .001. Both treatments improved disease severity and quality of life without any difference. CONCLUSIONS: EVLA and HLS are comparably effective concerning overall REVAS, improvement of disease severity, and quality of life. In terms of same site clinical recurrence and saphenofemoral refluxes, HLS is superior to EVLA 5 years after treatment. CLINICAL TRIAL REGISTRATION: ISRCTN18322872.

Comparison of one-year outcomes and quality of life between endovenous microwave ablation and high ligation and stripping of the great saphenous vein.

INTRODUCTION: The objective of this study is to evaluate and compare the effectiveness of endovenous microwave ablation (EMA) and high ligation and strippingn (HLS) of the great saphenous vein (GSV) in the treatment of varicose veins. METHODS: We included 182 patients in each EMA and HLS groups. Follow-up outcomes included AVVQ, VCSS, chronic venous insufficiency questionnaire-14 (CIVIQ14) score, clinical recurrence rate of varicose vein treatment, and patient satisfaction during the 1-year follow-up period. RESULTS: At the 1-year follow-up, no significant difference was found in the clinical recurrence rate of varicose veins between the EMA and HLS groups (p = .75). The duration of the operation and the length of hospital stay for patients in the EMA group was shorter than that for the HLS group (p < .01). The Aberdeen Varicose Vein Questionnaire (AVVQ), Venous Clinical Severity Score (VCSS) score, and ecchymosis were lower for patients who underwent EMA surgery (p < .01). CONCLUSION: Our research results confirm that EMA improves patients' quality of life with lower limb varicose veins, with EMA showing higher patient satisfaction.

Surgical Treatment of Persistent Glue Extension Into Common Femoral Vein Following Endovenous Glue Ablation.

Endovenous glue-induced thrombosis (EGIT) is a known complication of endovenous ablation therapy using cyanoacrylate closure glue to treat saphenous insufficiency, where glue extends into the common femoral vein (CFV), causing partial or complete occlusion. We report a case of class III EGIT (over 50% occlusion of CFV) in a young, healthy female who could not tolerate medical therapy. EGIT was treated with high ligation of the great saphenous vein and CFV patch repair. This is a safe option for patients who cannot tolerate anticoagulation therapy due to complications, physical or psychological limitations, or both.
