Noninvasive risk assessment of hepatic decompensation in patients with hepatitis B virus-related liver cirrhosis.

BACKGROUND AND AIM: Hepatic decompensation is a major complication of liver cirrhosis. We validated the predictive performance of the newly proposed CHESS-ALARM model to predict hepatic decompensation in patients with hepatitis B virus (HBV)-related cirrhosis and compared it with other transient elastography (TE)-based models such as liver stiffness-spleen size-to-platelet (LSPS), portal hypertension (PH), varices risk scores, albumin-bilirubin (ALBI), and albumin-bilirubin-fibrosis-4 (ALBI-FIB-4). METHODS: Four hundred eighty-two patients with HBV-related liver cirrhosis between 2006 and 2014 were recruited. Liver cirrhosis was clinically or morphologically defined. The predictive performance of the models was assessed using a time-dependent area under the curve (tAUC). RESULTS: During the study period, 48 patients (10.0%) developed hepatic decompensation (median 93 months). The 1-year predictive performance of the LSPS model (tAUC = 0.8405) was higher than those of the PH model (tAUC = 0.8255), ALBI-FIB-4 (tAUC = 0.8168), ALBI (tAUC = 0.8153), CHESS-ALARM (tAUC = 0.8090), and variceal risk score (tAUC = 0.7990). The 3-year predictive performance of the LSPS model (tAUC = 0.8673) was higher than those of the PH risk score (tAUC = 0.8670), CHESS-ALARM (tAUC = 0.8329), variceal risk score (tAUC = 0.8290), ALBI-FIB-4 (tAUC = 0.7730), and ALBI (tAUC = 0.7451). The 5-year predictive performance of the PH risk score (tAUC = 0.8521) was higher than those of the LSPS (tAUC = 0.8465), varices risk score (tAUC = 0.8261), CHESS-ALARM (tAUC = 0.7971), ALBI-FIB-4 (tAUC = 0.7743), and ALBI (tAUC = 0.7541). However, there was no significant difference in the predictive performance among all models at 1, 3, and 5 years (P > 0.05). CONCLUSIONS: The CHESS-ALARM score was able to reliably predict hepatic decompensation in patients with HBV-related liver cirrhosis and showed similar performance to the LSPS, PH, varices risk scores, ALBI, and ALBI-FIB-4.

Risk of Postoperative Thromboembolism in Men Undergoing Urological Prosthetic Surgery: An Assessment of 21,413 Men.

PURPOSE: We assessed venous thromboembolism (VTE) and associated risk factors following artificial urinary sphincter (AUS) and inflatable penile prosthesis (IPP) surgery. MATERIALS AND METHODS: Using IBM® MarketScan, a commercial claims database, patients undergoing AUS and IPP surgery were identified using CPT® and ICD (International Classification of Diseases)-10 procedure codes between 2008 and 2017. ICD-9 and -10 codes were used to identify health care visits associated with lower extremity deep vein thrombosis (DVT) and pulmonary embolism (PE) within 90 days of surgery. Covariates were assessed using a multivariable model to determine association with outcome of DVT and/or PE. RESULTS: A total of 21,413 men underwent AUS (4,870) or IPP (16,543) surgery between 2008 and 2017 with a median age of 62 years and 68 years, respectively. DVT and PE events following AUS and IPP surgery occurred in 1.54% and 1.04%, respectively. A history of varicose veins (HR 2.76; 95% CI 1.11-6.79), prior history of DVT (HR 13.65; 95% CI 7.4-25.19), or PE (HR 7.65; 95% CI 4.01-14.6) in those undergoing AUS surgery was highly associated with development of postoperative VTE. Likewise, prior history of DVT (HR 12.6; 95% CI 7.99-19.93) and PE (HR 8.9; 95% CI 5.6-14.13) was strongly associated with a VTE event following IPP surgery. CONCLUSIONS: In a large cohort of men undergoing AUS and IPP surgery, 1.54% and 1.04% of men experienced a VTE event within 90 days of surgery, respectively. Prior history of varicose veins, DVT, and PE was associated with an increased likelihood of developing a postoperative DVT or PE.

Venous leg symptoms, ecchymosis, and coldness in patients with peripheral varicose vein: A multicenter assessment and validation study (VEIN-VIOLET study).

OBJECTIVES: We aimed to evaluate peripheral varicose vein symptoms including ecchymosis and coldness by using the Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms (VEINES-QoL/Sym) questionnaire. METHODS: A total of 1120 patients were enrolled to the analysis after the exclusion of 199 patients who did not match the inclusion criteria. Patients were asked to answer the VEINES-Sym questionnaire and questions about ecchymosis and coldness. Scores of ecchymosis and coldness were calculated similar to VEINES-Sym questionnaire. Classifications of peripheral varicose vein were made according to the clinical part of clinical, etiological, anatomical, and pathophysiological classification system and patients with grade 2 or higher were considered as positive for peripheral varicose vein. RESULTS: Frequency of symptoms present in the VEINES-Sym instrument, ecchymosis and coldness were significantly higher in patients with peripheral varicose vein. Mean score of each symptom was significantly lower in peripheral varicose vein patients including scores of ecchymosis and coldness. Logistic regression analysis revealed that presence of hemorrhoids and all symptoms in VEINES-Sym questionnaire except restless leg were significantly and independently associated with peripheral varicose vein. Besides, ecchymosis (odds ratio: 2.04, 95% confidence interval: 1.34-3.08, p = 0.008) but not coldness was significantly and independently associated with peripheral varicose vein. There was also significant correlation of VEINES-Sym score with ecchymosis (r = 0.43, p < 0.001) and coldness (r = 0.47, p < 0.001). CONCLUSIONS: Venous leg symptoms present in VEINES-Sym questionnaire except restless legs, presence of hemorrhoids and ecchymosis are significantly and independently associated with peripheral varicose vein. Not only ecchymosis but also coldness has shown an independent association with total VEINES-Sym score.

Validation of the 3D SYM VEIN Symptom Assessment Tool.

OBJECTIVE: The aim was to validate the SYM VEIN consensus 3D scoring tool in chronic venous disease (CVD). METHODS: This was a prospective cohort study with a total of 35 consecutive patients with CVD. Patients with CVD undergoing saphenectomy were assessed with the revised Venous Clinical Severity Score (r-VCSS), the CIVIQ-20 quality of life score questionnaire, and the SYM VEIN consensus statement 3D system, pre-operatively and four weeks post-operatively. The total 3D score was tested for reliability, construct validity, and responsiveness. RESULTS: The total 3D score demonstrated good reliability and internal consistency (Cronbach's alpha 0.85). Principal component analysis identified three groups of symptoms (paraesthesia, burning pain, and pruritus, vs. heaviness, sensation of swelling and aching/pain, vs. restless leg and throbbing pain) demonstrating a high intragroup correlation and likely to share similar pathophysiology, indicative of adequate construct validity. The total 3D score showed a significant correlation with r-VCSS and CIVIQ-20 score (rho .46, p = .005 and rho .65, p < .001, respectively) indicative of adequate convergent validity. After saphenectomy, significant reductions (p < .001) of the total 3D, and 3D scores for all but two individual venous symptoms were observed, indicative of excellent responsiveness. Median total 3D score was reduced from 31 to 6 (83.8% decrease, p < .001), median r-VCSS was reduced from 6 to 0 (100% decrease, p < .001), and median CIVIQ-20 score was reduced from 24 to 14 (40% decrease, p < .001). The difference of median percentage change between r-VCSS and CIVIQ-20 score vs. total 3D score was significant (p = .005 and p < .001, respectively). CONCLUSION: The total SYM VEIN 3D score has good reliability, construct validity and excellent responsiveness, although less prone to change after saphenectomy compared with r-VCSS.

Cost-Effectiveness of Current and Emerging Treatments of Varicose Veins.

OBJECTIVES: To analyze the cost-effectiveness of current technologies (conservative care [CONS], high-ligation surgery [HL/S], ultrasound-guided foam sclerotherapy [UGFS], endovenous laser ablation [EVLA], and radiofrequency ablation [RFA]) and emerging technologies (mechanochemical ablation [MOCA] and cyanoacrylate glue occlusion [CAE]) for treatment of varicose veins over 5 years. METHODS: A Markov decision model was constructed. Effectiveness was measured by re-intervention on the truncal vein, re-treatment of residual varicosities, and quality-adjusted life-years (QALYs) over 5 years. Model inputs were estimated from systematic review, the UK National Health Service unit costs, and manufacturers' list prices. Univariate and probabilistic sensitivity analyses were undertaken. RESULTS: CONS has the lowest overall cost and quality of life per person over 5 years; HL/S, EVLA, RFA, and MOCA have on average similar costs and effectiveness; and CAE has the highest overall cost but is no more effective than other therapies. The incremental cost per QALY of RFA versus CONS was £5,148/QALY. Time to return to work or normal activities was significantly longer after HL/S than after other procedures. CONCLUSIONS: At a threshold of £20,000/QALY, RFA was the treatment with highest median rank for net benefit, with MOCA second, EVLA third, HL/S fourth, CAE fifth, and CONS and UGFS sixth. Further evidence on effectiveness and health-related quality of life for MOCA and CAE is needed. At current prices, CAE is not a cost-effective option because it is costlier but has not been shown to be more effective than other options.

Clinical presentation of women with pelvic source varicose veins in the perineum as a first step in the development of a disease-specific patient assessment tool.

OBJECTIVE: Pelvic venous incompetence can cause symptomatic varicose veins in the perineum, buttock, and thigh. Presentation, symptom severity, and response to treatment of pelvic source varicose veins are not well defined. Currently available tools to measure the severity of lower extremity venous disease and its effects on quality of life may be inadequate to assess disease severity in these patients. The purpose of this study was to evaluate the histories, demographics, and clinical presentations of women with pelvic source varicose veins and to compare these data to a population of women with nonpelvic source varicose veins. METHODS: A total of 72 female patients with symptomatic pelvic source varicose veins were prospectively followed up. Age, weight, height, parity, and birth weights of offspring were recorded. Both pelvic source varicose veins and saphenous incompetence were identified by duplex ultrasound. Patients were queried as to their primary symptoms, activities that made their symptoms worse, and time when their symptoms were most prominent. Severity of disease was objectively evaluated using the revised Venous Clinical Severity Score (rVCSS) and 10-point numeric pain rating scale (NPRS). RESULTS: Compared with women without a pelvic source of varicose veins (N = 1163), patients with pelvic source varicose veins were younger (mean, 44.6 ± 8.6 vs 52.6 ± 12.9 years; P < .001), had lower body mass index (mean, 21.9 ± 2.8 vs 25.8 ± 6.2; P < .001), and had larger babies than the U.S. population mean (mean, 3656 ± 450 g vs 3389 ± 466 g; P < .001). The most common symptoms were aching (68%), throbbing (47%), and heaviness (35%). In premenopausal patients, 70% noted that symptoms were worst during menses. NPRS score varied from 0 to 8 (mean, 4.9). The correlation between rVCSS (mean 5.6 ± 1.9) and NPRS was small (r = 0.26; P = .03). There was a modest correlation between older age and lower NPRS scores (r = -0.39; P < .001). CONCLUSIONS: Women with pelvic source varicose veins are a unique subset of patients. They are younger and thinner than those with nonpelvic source varicose veins, have larger infants than the general U.S. population, and have an inverse correlation between age and pain. As the majority of premenopausal patients have increased symptoms during menses, this may be due to hormonal influence. As it is poorly associated with patient-reported discomfort, the rVCSS is a poor tool for evaluating pelvic source varicose veins. A disease-specific tool for the evaluation of pelvic source varicose veins is critically needed, and this study is a first step in that endeavor.

[Von Korff questionnaire in assessment of social disadaptation and therapeutic results in women with pelvic varicose veins]. / Anketa Van Korffa v otsenke sotsial'noi dezadaptatsii i rezul'tatov lecheniia patsientok s varikoznoi bolezn'iu taza.

AIM: The present study was conducted to examine the possibilities of the Von Korff questionnaire in assessing the impact of pelvic pain on social activity and working ability of women with pelvic varicose veins (PVV) and evaluating the results of treatment of the pathology involved. PATIENTS AND METHODS: The Von Korff questionnaire was administered in a total of 80 women presenting with PVV in order to assess the results of conservative and surgical treatment of PVV. RESULTS: Using the Von Korff questionnaire made it possible to objectively evaluate the psychosocial impact of chronic pelvic pain (CPP). It was determined that in 56 patients the presence of PVV and CPP was accompanied by a low level of social disadaptation and formation of grade I disability. 24 women were found to have moderate and high levels of social disadaptation and grade II-IV disability. Studying the outcomes of conservative and surgical treatment of PPV as assessed by means of the Von Korff questionnaire demonstrated high efficacy of the therapeutic techniques used. In patients subjected to surgical interventions, the CPP degree decreased from 7.6±0.9 to 1.6±0.9 points, the level of social disadaptation fell from 2.8±0.6 to 0.5±0.3 points, and the grade of disability decreased from 2.9±0.4 to 0.8±0.4, which may be regarded as complete restoration of social activity. DISCUSSION: The Von Korff questionnaire used in our study made it possible to objectively evaluate the impact of CPP related to pelvic varicose veins on formation of social disadaptation in women and a decrease in their working ability. In the general structure of the disease, 75% of women appeared to have a low level of social disadaptation and grade I disability, with a third having grade II, III and IV disability and a moderate-to-high level of social disadaptation. In 25% of women, the determined degree of disability averagely amounted to 2.9±0.4, thus suggesting their significant social disadaptation. CONCLUSION: The carried out study showed that the Von Korff questionnaire is an objective and demonstrative tool of clinical determination of the severity of pelvic varicose veins, as well as the effect of CPP on both everyday and social activity of women suffering from the pathology concerned.

A Cost-effectiveness Analysis of Surgery, Endothermal Ablation, Ultrasound-guided Foam Sclerotherapy and Compression Stockings for Symptomatic Varicose Veins.

OBJECTIVE: The aim was to investigate the cost-effectiveness of interventional treatment for varicose veins (VV) in the UK NHS, and to inform the national clinical guideline on VV, published by the National Institute of Health and Care Excellence. DESIGN: An economic analysis was constructed to compare the cost-effectiveness of surgery, endothermal ablation (ETA), ultrasound-guided foam sclerotherapy (UGFS), and compression stockings (CS). The analysis was based on a Markov decision model, which was developed in consultation with members of the NICE guideline development group (GDG). METHODS: The model had a 5-year time horizon, and took the perspective of the UK National Health Service. Clinical inputs were based on a network meta-analysis (NMA), informed by a systematic review of the clinical literature. Outcomes were expressed as costs and quality-adjusted life years (QALYs). RESULTS: All interventional treatments were found to be cost-effective compared with CS at a cost-effectiveness threshold of £20,000 per QALY gained. ETA was found to be the most cost-effective strategy overall, with an incremental cost-effectiveness ratio of £3,161 per QALY gained compared with UGFS. Surgery and CS were dominated by ETA. CONCLUSIONS: Interventional treatment for VV is cost-effective in the UK NHS. Specifically, based on current data, ETA is the most cost-effective treatment in people for whom it is suitable. The results of this research were used to inform recommendations within the NICE guideline on VV.

Assessment of thrombotic adverse events and treatment patterns associated with varicose vein treatment.

OBJECTIVE: This retrospective study assessed varicose vein treatment patterns and associated thrombotic complications in a real-world setting. METHODS: A retrospective study was conducted with health care claims data from Truven Health, covering more than 40 million insured lives per year and representing all U.S. census regions. The study sample included subjects aged ≥ 18 years with a new diagnosis of varicose veins who had received at least one invasive treatment (eg, surgery, endovenous thermal ablation [radiofrequency or laser], or sclerotherapy [liquid or foam]). The adverse events of interest included a coded diagnosis of deep venous thrombosis (DVT) or pulmonary embolism within 30 days of a claim for invasive treatment. Patients treated between January 1, 2008, and June 30, 2012, were observed for up to 2 years after diagnosis. RESULTS: There were 985,632 unique subjects diagnosed with varicose veins; of them, a total of 131,887 subjects met all of the study criteria: 63,033 (47.8%) having multiple therapies; 22,980 (17.4%) having laser ablation; 21,637 (16.4%) having radiofrequency ablation; 12,708 (9.6%) having sclerotherapy; and 11,529 (8.7%) having surgery. The mean age of the sample was 52.8 years, ranging from 51.5 years (surgery cohort) to 54.5 years (radiofrequency ablation cohort); 77% of the sample was female, ranging from 71% (radiofrequency ablation cohort) to 92% (sclerotherapy cohort). The mean time to treatment after diagnosis was 105 days, ranging from 75 days (sclerotherapy cohort) to 116 days (radiofrequency ablation cohort). The diagnosed prevalence (percentage of subjects within each treatment cohort) of DVT was as follows: radiofrequency ablation, 4.4%; multiple therapies--same day, 3.4%; laser ablation, 3.1%; multiple therapies--deferred, 2.6%; surgery, 2.4%; and sclerotherapy, 0.8%. For pulmonary embolism, the diagnosed prevalence was as follows: radiofrequency ablation, surgery, and laser ablation, 0.3% each; and multiple therapies--same day, multiple therapies--deferred, and sclerotherapy, 0.2% each. CONCLUSIONS: Thrombotic complications associated with invasive varicose vein treatments in the real-world setting may be higher than what has been reported in clinical trials, particularly in regard to DVT after endovenous thermal ablation therapy. A better understanding of these patterns of adverse events may have an impact on new strategies to safely and effectively manage patients with varicose veins.

CVD: a condition of underestimated severity.

Chronic venous disease (CVD) affects approximately a quarter of the adult population and causes a considerable burden on the health of these patients. The true extent of the severity of the disease is hampered because of reduced public awareness, operational difficulties in diagnosis, and the perception that varicose veins are mainly a cosmetic inconvenience. Consequently the disease receives little attention in public health care systems which focus on life threatening conditions and those which cause obvious morbidity like cancer, cardiac disease and stroke. This review aims to correct these misconceptions by addressing the full scope of CVD, including the post-thrombotic syndrome and venous ulceration. The severity of conditions like telangectasiae and edema and the symptoms they cause are frequently underestimated, especially if varicose veins are not present to alert the patient or doctor. The definition, diagnosis, scope, epidemiology, progression and cost of CVD are discussed with evidence to explain how these underestimate the severity of the disease. It is anticipated that once CVD achieves greater recognition this will open up greater opportunities for treatment. These include surgery, endovenous ablation, stenting, compression, venoactive drugs like micronized purified flavonoid fraction and other drugs such as sulodexide and pentoxifylline.

Study to develop a waiting list prioritization score for varicose vein surgery.

BACKGROUND: The objective of this study was to develop a clear-cut, objective system for prioritization of patients on the waiting list for varicose vein surgery, to enable organization of access to the health service. METHODS: During earlier phases, we selected which variables should be taken into account for the prioritization scale, such as clinical presentation, varicose vein size, complications, work situation, and influence on quality of life. In the last phase, to determine the relative weight of each variable, structured surveys (personal interviews or by e-mail) were performed of the convenience samples from the groups related to the healthcare process, including patients, relatives, and healthcare professionals. RESULTS: The structured survey we utilized was administered to a sample of 762 subjects that included 290 patients, 99 relatives, 179 general practitioners, 32 nurses, and 162 vascular surgeons. The final score included clinical manifestations (46.1% of relative importance), size of the varicose veins (8.2%), complications (18.3%), influence on quality of life (18.2%), and aggravating work factors (9.2%). CONCLUSIONS: The prioritization system agreed upon by all the groups involved could allow for objective and transparent prioritization and lead to the rationalization of access to varicose vein surgery for patients on the waiting list.

Short-term gain for long-term pain? Which patients should be treated and should we ration?

OBJECTIVES: Treatments of common conditions which do not affect mortality often become sidelined in the drive to improve efficiency and reduce costs. The rationing of patients is a divisive but crucial component to universal health care. How should this be accomplished? METHODS AND RESULTS: In this article we examine the outcomes of various rationing methods in varicose veins. CONCLUSIONS: No method is perfect and treatment of symptoms and complications should remain the target for all physicians.

Assessment of the infiltration of inflammatory cells in the walls of thrombotic varicose veins.

The purpose of this study is to describe the infiltration of mast cells as well as T and B cells in the walls of thrombotic varicose great saphenous veins. Sections were obtained from venous segments of patients with varicose veins and stained with toluidine blue for mast cells, while immunohistochemistry for T cells (using CD45RO antibody) and B cells (CD20) was analyzed using light microscopy after staining. The number of mast cells, T, and B cells observed in thrombotic varicose veins was 1.925 ± 1.203, 72.038 ± 34.707, and 19.519 ± 9.899, respectively. In varicose veins, the corresponding values were 0.265 ± 0.099, 0.600 ± 0.432, and 0.488 ± 0.400. Significantly higher number of mast cells, T cells, and B cells were observed in thrombotic varicose veins compared with control veins. A significant difference was not observed between the varicose group and control group. Thrombi in varicose veins can induce infiltration of mast cells, T cells, and B cells, which may be involved in the remodeling of venous walls.

Generic health-related quality of life is significantly worse in varicose vein patients with lower limb symptoms independent of CEAP clinical grade.

OBJECTIVES: To determine the relationship between lower limb symptoms and generic health-related quality of life (HRQL) in patients with varicose veins (VV). METHODS: 284 patients on the waiting list for VV treatment completed the Short Form-12 (SF12) and a questionnaire asking about the presence of lower limb symptoms commonly attributed to venous disease (pain or ache, itching, tingling, cramp, restless legs, a feeling of swelling, and heaviness). RESULTS: Median age was 57 years (interquartile range 45-67); 100 (35%) were male, and 182 (64%) had CEAP clinical grade 2 or 3 disease. Jonckheere-Terpstra test for trend revealed that both physical (P < .0005) and mental (P = .001) HRQL worsened as the reported number of symptoms increased. Patients reporting tingling (P = .016, Mann-Whitney U test), cramp (P = .001), restless legs (P < .0005), swelling (P < .0005), and heaviness (P < .0005) had a significantly worse physical HRQL than those who did not. Mental HRQL was also significantly worse in patients with tingling (P = .010), cramp (P = .008), restless legs (P = .040), swelling (P = .001), and heaviness (P = .035). These significant relationships remained, and pain was also correlated with worse physical HRQL (P = .011), when linear regression was performed to control for CEAP clinical grade, age and sex. CONCLUSIONS: Physical and mental HRQL is significantly worse in VV patients with lower limb symptoms irrespective of the clinical stage of disease. This observation confirms that VV are not primarily a cosmetic problem and that NHS rationing of treatment to those with CEAP C4-6 disease excludes many patients who would benefit from intervention in terms of HRQL. Generic HRQL instruments also allow comparison with interventions for other chronic conditions.

Prognostic assessment in patients with hepatic encephalopathy.

Hepatic encephalopathy (HE) is a common complication of liver failure that is associated with poor prognosis. However, the prognosis is not uniform and depends on the underlying liver disease. Acute liver failure is an uncommon cause of HE that carries bad prognosis but is potentially reversible. There are several prognostic systems that have been specifically developed for selecting patients for liver transplantation. In patients with cirrhosis the prognosis of the episode of HE is usually dictated by the underlying precipitating factor. Acute-on-chronic liver failure is the most severe form of decompensation of cirrhosis, the prognosis depends on the number of associated organ failures. Patients with cirrhosis that have experienced an episode of HE should be considered candidates for liver transplant. The selection depends on the underlying liver function assessed by the Model for End-stage Liver Disease (MELD) index. There is a subgroup that exhibits low MELD and recurrent HE, usually due to the coexistence of large portosystemic shunts. The recurrence of HE is more common in patients that develop progressive deterioration of liver function and hyponatremia. The bouts of HE may cause sequels that have been shown to persist after liver transplant.

[Endoscopic assessment of large bowel and safety of bowel preparation and sedoanalgesia in patients with advanced liver cirrhosis]. / Ocena endoskopowa jelita grubego oraz bezpieczenstwo przygotowania jelita i sedoanalgezji u chorych z zaawansowana marskoscia watroby.

INTRODUCTION: In patients with advanced liver cirrhosis endoscopic images of large bowel are still poorly recognized in comparison with upper digestive tract. At present, the colonoscopy is examination routinely performed during qualification to liver transplantation. The purpose of this study was to retrospectively analyze colonoscopic reports and to assess a safety of all procedures realized before and during colonoscopy. MATERIAL AND METHODS: The study included 46 patients with liver cirrhosis (males 54.4%, females 45.6%) at age of 18-66 years, hospitalized between 2007-2009 for qualification to liver transplantation. Colonoscopy was done in short general sedation, and standard bowel preparation involved 256 g of polyethylene glycol dissolved in 4 liters of fluid given to the patient one day before colonoscopy. RESULTS: In 26.1% of patients no pathology was found on colonoscopy. Anal/rectal varices were found in 41.3% of patients, lesions classified as portal colopathy in 13% of patients and sigmoid diverticula in 8.7% of patients. In 17 (37%) of patients colonoscopy disclosed 46 polyps in large bowel (38 polyps in 12 patients were retrieved for histopathological examination). In 4 (8.7%) patients polyps were hyperplastic, in 6 (about 13%) tubular adenomas of low grade dysplasia and in 2 (4.35%) tubulo-villous adenomas of low grade dysplasia. Tubulo-villous adenomas were found only in patients with alcoholic cirrhosis. Colonoscopy did not worsen the general clinical state of any patient, however, as compared with compensated cirrhotics, the patients with ascites and/or peripheral edema showed features of water retention (larger body mass changes -0.50 +1.21 kg vs 0.23 +1.38 kg; p < 0.05). After colonoscopy a significant increase of body temperature by 0.23 +0.30 degrees C; p < 0.001 was noted, while examination had no significant effect on serum creatinine level and white blood cell number. CONCLUSIONS: Liver cirrhosis may predispose to certain diseases of the large bowel, including portal colopathy and adenomatous polyps. Procedures accomplished before and during colonoscopy seem to be safe for cirrhotic patients, however, in decompensated cirrhosis exists a tendency to further water retention.

[Correlation of risk factors and complications in the conventional surgery of varicose veins]. / Corelatii între factorii de risc si complicatii în chirurgia conventionala a bolii varicoase.

The primary varicose vein disease, a largely spread affection, constitutes a present challenge and a major health concern because of its increased prevalence and the high expenses of treatment and patient care. Due to the modern instruments, preoperative investigations and the increased understanding of the physiopathological mechanisms in the alteration of venous return, this objective can be achieved easier. Nevertheless, according to ananalytical retrospective observational study performed at the Surgery Clinic II, Cluj-Napoca, on 957 patients with varices of lower extremities, postoperative complications occur in 11 percent, due to additional costs and patients' negative social and professional consequences. Another study performed at the same clinic on 1066 patients with primary varicose disease reveals the high incidence of the risk factors (62%) and progressive complications (44%). Furthermore, the study shows that patients tend to seek help at late stages of disease, which requires a longer hospitalization period and implicitly higher costs of postoperative care and treatment. A correct sanitary education of the affected population would reduce the treatment expenses. In addition, a more efficiently control of the disease, the prevention of progressive complications incidents, and the adequate surgical procedure that prevent the postoperative complications, would also reduce the costs. Considering the high number of surgical interventions involved in varicose disease treatment, the results presented in this study are of great significance for both surgeons and the institutions that provide the funds for treatment. surgical procedure that prevent the postoperative complications, would also reduce the costs. Considering the high number of surgical interventions involved in varicose disease treatment, the results presented in this study are of great significance for both surgeons and the institutions that provide the funds for treatment.

Best practice for assessment of patients with varicose veins.

BACKGROUND: Varicose veins are a significant health problem which attract much medicolegal attention. Recent publications have suggested "best practice" regarding assessment of patients with varicose veins. A retrospective audit was performed comparing clinical practice in a New Zealand teaching hospital with suggested standards. METHODS: Clinic letters from 80 patients awaiting varicose vein surgery were reviewed. Data were collated regarding presenting problem, relevant medical history, clinical findings on examination, further investigations, and outcome. RESULTS: Presenting complaint was noted for 99% of patients but actual symptoms were only recorded for 41%. The degree of disability caused by varicose veins was documented for 33% and patient concerns in 4%. Half of the patients presented with leg ulcers but ankle-brachial indices (ABPIs) were only recorded in 26% of clinic letters. Duplex scanning was recommended prior to surgery for 69% of patients and hand held Doppler assessment of venous disease was recorded in 61% cases. Clinic letters did not specify the nature and extent of disease in 6% of cases, and although every patient was recommended for surgery, the exact procedure was specified in only 24%. Details of surgical risks and complications were only present in 20% of letters, and only 21% of patients received a printed information sheet. CONCLUSIONS: The quality of the data recorded in the clinic letters of fell below suggested standards for assessment of patients with varicose veins. Improving the documentation of patient assessment will allow better communication between providers of healthcare and make clinical errors less likely.

Objetivo: Avaliar a influência do refluxo das veias musculares da panturrilha (surais e geniculares) na função da bomba muscular da panturrilha em pacientes com varizes primárias nos membros inferiores. Métodos: Estudo transversal prospectivo, no qual os pacientes foram avaliados por envio de exame físico, mapeamento duplex e pletismografia a ar. Foram selecionados 120 pacientes divididos em 2 grupos (60 indivíduos em cada um). O primeiro grupo apresentava refluxo das veias musculares da panturrilha e o segundo grupo apresentava ausência de refluxo. Cada grupo foi analisado com pletismografia para estudo da função da bomba da panturrilha. As variáveis estudadas foram fração de ejeção. fração do volume residual, volume ejetado e índice de enchimento venoso para membro inferior direito e esquerdo. Resultados: No grupo com refluxo, índices de fração de ejeção abaixo de 60 por cento (com p menor 0,00) foram encontrados em 82,3 por cento (em perna esquerda) e em 74,6 por cento (em perna direita) dos casos. Índices de fração do volume residual acima de 60 por cento ...
