ABSTRACT

Objective: This economic evaluation aims to provide a preliminary assessment of the cost-effectiveness of radiofrequency ablation (RFA) compared with argon plasma coagulation (APC) when used to treat APC-refractory gastric antral vascular ectasia (GAVE) in symptomatic patients.Methods: A Markov model was constructed to undertake a cost-utility analysis for adults with persistent symptoms secondary to GAVE refractory to first line endoscopic therapy. The economic evaluation was conducted from a UK NHS and personal social services (PSS) perspective, with a 20-year time horizon, comparing RFA with APC. Patients transfer between health states defined by haemoglobin level. The clinical effectiveness data were sourced from expert opinion, resource use and costs were reflective of the UK NHS and benefits were quantified using Quality Adjusted Life Years (QALYs) with utility weights taken from the literature. The primary output was the Incremental Cost-Effectiveness Ratio (ICER), expressed as cost per QALY gained.Results: Over a lifetime time horizon, the base case ICER was £4840 per QALY gained with an 82.2% chance that RFA was cost-effective at a threshold of £20,000 per QALY gained. The model estimated that implementing RFA would result in reductions in the need for intravenous iron, endoscopic intervention and requirement for blood transfusions by 27.1%, 32.3% and 36.5% respectively. Compared to APC, RFA was associated with an estimated 36.7% fewer procedures.Conclusions: RFA treatment is likely to be cost-effective for patients with ongoing symptoms following failure of first line therapy with APC and could lead to substantive reductions in health care resource.

ABSTRACT

Central airway obstruction (CAO) is associated with significant morbidity and increased mortality. Bronchoscopic electrosurgical and laser ablative tools have proven to be safe and effective instruments for the treatment of malignant CAO. Although therapeutic modalities such as electrocautery, argon plasma coagulation, and laser have been used for decades, additional tools including radiofrequency ablation catheters continue to be developed for the treatment of CAO. These modalities are considered safe in the hands of experienced operators, although serious complications can occur. This review describes various electrosurgical and laser therapy tools used for the treatment of malignant CAO along with the specific advantages and disadvantages of each device.

ABSTRACT

PURPOSE: This study aims to compare the effects and prognosis of medical thoracoscopy-assisted argon plasma coagulation (APC) combined with electrosurgical unit (ESU) surgery, video-assisted thoracic surgery (VATS), and pleurodesis surgery, in providing appropriate treatment for elderly refractory pneumothorax patients. METHODS: Patients with refractory pneumothorax aged over 65 years were divided into three groups: APC combined with ESU (N = 20), VATS (N = 26), and pleurodesis (N = 24). Data on demographic characteristics, lung function evaluation, and short- and long-term prognoses were collected. RESULTS: Following surgery, compared with the APC-ESU and pleurodesis groups, patients in the VATS group demonstrated poor short-term prognoses, with high pleural effusion drainage levels and high visual analog scores (VAS; P <0.05). After the surgery, St. George's Respiratory Questionnaire (SGRQ) scores in the pleurodesis group were slightly elevated, whereas SGRQ scores in both the APC-ESU and VATS groups demonstrated a continual decrease. Finally, medical resource consumption analysis demonstrated a significant difference in hospitalization costs among the three groups; the VATS group being the most expensive. CONCLUSION: Medical thoracoscopy-assisted APC combined with ESU is a safe, effective, and affordable treatment for elderly patients with refractory pneumothorax.

ABSTRACT

BACKGROUND: Abdominoplasty is one of the most common procedures in plastic surgery, and energy-based tissue dissection techniques have become the gold standard. Despite its frequency, abdominoplasty is still associated with high complication rates. OBJECTIVES: The authors compared clinical and economic data of 4 methods of energy-based tissue dissection in a randomized, open-label study. METHODS: A total of 57 patients were preoperatively randomized into 4 groups: electrocautery, Ultracision Harmonic Scalpel, argon plasma coagulation, and PEAK-Plasmablade. Demographic and operational data as well as information on the postoperative course and complications were collected. For economic analysis, quotes were obtained from the device companies or official suppliers. RESULTS: Duration of surgery, drainage quantity, and wound healing complications did not differ significantly between groups. The Ultracision method caused significantly greater blood loss compared with all other techniques (P < 0.01). PEAK and Ultracision devices entailed greater surgical costs compared with APC and electrocautery. CONCLUSIONS: All methods evaluated can be applied safely and effectively in abdominoplasty procedures. However, these data demonstrate a significantly higher blood loss for the Ultracision Harmonic Scalpel. Considering the clinical data, the higher costs of PEAK and Ultracision methods appear unjustified.

ABSTRACT

BACKGROUND AND AIMS: Endoscopic resection (ER) is safe and effective for Barrett's esophagus (BE) containing high-grade dysplasia (HGD) or mucosal adenocarcinoma (T1A). The risk of metachronous neoplasia is reduced by ablation of residual BE by using radiofrequency ablation (RFA) or argon plasma coagulation (APC). These have not been compared directly. We aimed to recruit up to 100 patients with BE and HGD or T1A confirmed by ER over 1 year in 6 centers in a randomized pilot study. METHODS: Randomization was 1:1 to RFA or APC (4 treatments allowed at 2-month intervals). Recruitment, retention, dysplasia clearance, clearance of benign BE, adverse events, healthcare costs, and quality of life by using EQ-5D, EORTC QLQ-C30, or OES18 were assessed up to the end of the trial at 12 months. RESULTS: Of 171 patients screened, 76 were randomized to RFA (n = 36) or APC (n = 40). The mean age was 69.7 years, and 82% were male. BE was <5 cm (n = 27), 5 to 10 cm (n = 45), and >10 cm (n = 4). Sixty-five patients completed the trial. At 12 months, dysplasia clearance was RFA 79.4% and APC 83.8% (odds ratio [OR] 0.7; 95% confidence interval [CI], 0.2-2.6); BE clearance was RFA 55.8%, and APC 48.3% (OR 1.4; 95% CI, 0.5-3.6). A total of 6.1% (RFA) and 13.3% (APC) had buried BE glands. Adverse events (including stricture rate after starting RFA 3/36 [8.3%] and APC 3/37 [8.1%]) and quality of life scores were similar, but RFA cost $27491 more per case than APC. CONCLUSION: This pilot study suggests similar efficacy and safety but a cost difference favoring APC. A fully powered non-inferiority trial is appropriate to confirm these findings.

ABSTRACT

Endoscopic treatment such as endoscopic submucosal dissection (ESD) or argon plasma coagulation (APC) is widely performed to treat gastric low-grade dysplasia (LGD). We aimed to evaluate the clinical efficacy of APC versus ESD for gastric LGD in terms of cost-effectiveness. This was a retrospective review of patients with gastric LGD who were treated with endoscopic intervention (APC or ESD) between March 2011 to December 2015. Fifty-nine patients treated with APC and 124 patients treated with ESD were included. Patients in the APC group were significantly older (mean age, 67.68 vs 63.90 years, respectively, P < .01), had an increased rate of Helicobacter pylori infection (27.1 vs 10.5%, respectively, P < .01), and had a higher mean Charlson Comorbidity Index score (2.32 vs 0.38, respectively, P < .01) than those in the ESD group. The 2 groups did not differ in tumor size, location, macroscopic morphology, or surface configuration. The procedure time (11.31 vs56.44 minutes, respectively, P < .01), and hospital stay (3.2 vs 5.6 days, respectively, P < .01) were significantly, shorter in the APC group than in the ESD group. Additionally, the cost incurred was significantly, lower in the APC group than in the ESD group (962.03 vs 2,534.80 dollars, respectively, P < .01). APC has many advantages related to safety, and cost-effectiveness compared with ESD. Therefore, APC can be considered an alternative treatment option for gastric LGD.
