With the introduction of laparoscopic antireflux surgery (LARS) for gastro-oesophageal reflux disease (GORD) along with the increasing efficacy of modern medical treatment, a direct comparison is warranted. The 3-year interim results of a randomised study comparing both the efficacy and safety of LARS and esomeprazole (ESO) are reported.
LOTUS is an open, parallel-group multicentre, randomised and controlled trial conducted in dedicated centres in 11 European countries. LARS was completed according to a standardised protocol, comprising a total fundoplication and a crural repair. Medical treatment comprised ESO 20 mg once daily, which could be increased stepwise to 40 mg once daily and then 20 mg twice daily in the case of incomplete GORD control. The primary outcome variable was time to treatment failure (Kaplan-Meier analysis). Treatment failure was defined on the basis of symptomatic relapse requiring treatment beyond that stated in the protocol.
554 patients were randomised, of whom 288 were allocated to LARS and 266 to ESO. The two study arms were well matched. The proportions of patients who remained in remission after 3 years were similar for the two therapies: 90% of surgical patients compared with 93% medically treated for the intention to treat population, p = 0.25 (90% vs 95% per protocol). No major unexpected postoperative complications were experienced and ESO was well tolerated. However, postfundoplication complaints remain a problem after LARS.
Over the first 3 years of this long-term study, both laparoscopic total fundoplication and continuous ESO treatment were similarly effective and well-tolerated therapeutic strategies for providing effective control of GORD.
随着腹腔镜抗反流手术(LARS)被用于治疗胃食管反流病(GORD),以及现代医学治疗效果的不断提高,有必要进行直接比较。本文报告了一项随机研究的3年中期结果,该研究比较了LARS和埃索美拉唑(ESO)的疗效和安全性。
LOTUS是一项开放、平行组多中心随机对照试验,在11个欧洲国家的专门中心进行。LARS按照标准化方案完成,包括全胃底折叠术和膈脚修补术。药物治疗包括每日一次服用20mg ESO,若GORD控制不完全,可逐步增加至每日一次40mg,然后每日两次20mg。主要结局变量是治疗失败时间(Kaplan-Meier分析)。治疗失败的定义是出现症状复发,需要超出方案规定的治疗。
554例患者被随机分组,其中288例被分配接受LARS治疗,266例接受ESO治疗。两个研究组匹配良好。两种治疗方法在3年后仍处于缓解状态的患者比例相似:意向性治疗人群中,手术患者为90%,药物治疗患者为93%,p = 0.25(按方案分析分别为90%和95%)。未出现重大意外术后并发症,ESO耐受性良好。然而,LARS术后胃底折叠术后的不适仍是一个问题。
在这项长期研究的前3年中,腹腔镜全胃底折叠术和持续ESO治疗都是控制GORD的有效且耐受性良好的治疗策略,二者效果相似。
