Erosion of the laparoscopic adjustable gastric band (LAGB) into the lumen of the stomach is a recognised complication of this procedure. We undertook a systematic literature review of the incidence, clinical features and management of erosions occurring after LAGB. A systematic search of relevant medical databases for full-text original articles looking for LAGB patients and reported erosions was conducted. We focussed on incidence, aetiology, clinical presentation, treatment, complications and weight loss. Twenty-five studies of LAGB reported 231 erosions in 15,775 patients (overall incidence of 1.46%). The mean number of patients per study was 631 (±486), and the mean follow-up was 3.73 (±2.4) years. In four reports involving less than 100 patients, there were 27 erosions in a total of 270 patients (10%) compared with 180 erosions in 12,978 patients (1.386%) in the remaining 21 reports. Multiple regression analysis showed that erosion rate was significantly predicted by number of patients and number of years of surgeon experience (r(2) = 0.186). Treatment was most commonly by removal of the band, repair of the stomach and later, band replacement. Other options were removal alone or conversion to another procedure. Weight loss was retained after treatment of the erosion with a mean weight loss at final follow-up of 50.34 ± 3.9 percent excess weight loss. Incidence of erosion after gastric banding is relatively low and can be related to surgeon experience. The most common treatment described in the literature is removal of the eroded band with delayed replacement. Replacement of the band is associated with maintenance of weight loss.
胃腹腔镜可调胃束带（LAGB）侵蚀到胃腔是该手术的一种公认并发症。我们对 LAGB 后发生侵蚀的发生率、临床特征和处理进行了系统的文献复习。对寻找 LAGB 患者和报告侵蚀的相关医学数据库进行了系统的全文原始文章搜索。我们重点关注发生率、病因、临床表现、治疗、并发症和减重。25 项 LAGB 研究报告了 15775 例患者中的 231 例侵蚀（总体发生率为 1.46%）。每项研究的平均患者数为 631（±486），平均随访时间为 3.73（±2.4）年。在 4 项涉及少于 100 例患者的报告中，共有 270 例患者发生 27 例侵蚀（10%），而在其余 21 项报告中，12978 例患者中有 180 例侵蚀（1.386%）。多元回归分析显示，侵蚀率与患者人数和外科医生经验年限显著相关（r²=0.186）。治疗最常见的方法是移除束带、修复胃，然后更换束带。其他选择是单独移除或转换为另一种手术。在治疗侵蚀后保留了减重效果，最终随访时平均减重为 50.34±3.9%超重减轻。胃束带术后侵蚀的发生率相对较低，可能与外科医生的经验有关。文献中描述的最常见的治疗方法是移除侵蚀的束带，然后延迟更换。更换束带与维持减重有关。
