Abstract

Abstract Objectives  Endoscopic mucosal resection (EMR) is useful for removing colon polyps and is generally carried out by one doctor. It is occasionally difficult for colorectal polyps to be removed by EMR. In such cases, EMR is performed by the main doctor and an assistant doctor (the two-person method). However, the efficacy and safety of EMR in the two-person method remain unclear. This study aimed to compare the procedure time and incomplete resection rate (IRR) by the two- and single-person methods of EMR for polyp removal. Materials and Methods  Data from colorectal polyps resected by EMR were reviewed retrospectively and divided into two groups: general procedure/single- ( n  = 215) or two-person method ( n  = 56). The IRR, the procedure time, and the incidence of adverse events were compared between these methods. Results  A total of 152 patients and 271 lesions were included in this study. The mean procedure time for polypectomy was significantly shorter in the two-person method group than in the general procedure group (median time: 3.38 minutes vs. 6.56 minutes; p  < 0.001). Additionally, the IRR for polyps was significantly lower in the two-person methods group than in the single-person methods group (2/56, 3.6% vs. 47/215, 21.9%; p  = 0.001). None of the patients in the two-person method group presented with delayed bleeding. Conclusions  The two-person method for EMR was more effective than the single-person method. Therefore, this method may replace the conventional one-operator method in the future.
内镜下二人法粘膜切除术的疗效和安全性
抽象目标 内镜黏膜切除术(EMR)可用于切除结肠息肉,通常由一名医生进行。结肠息肉有时很难通过EMR切除。在这种情况下,EMR由主医生和助理医生执行(两人方法)。然而,EMR在两人方法中的疗效和安全性尚不清楚。本研究旨在比较两人和单人EMR切除息肉的手术时间和不完全切除率(IRR)。材料和方法 回顾性分析了经EMR切除的结直肠息肉的数据,并将其分为两组:常规手术/单次(n = 215)或两人方法(n = 56)。比较两种方法的内部收益率、手术时间和不良事件发生率。后果 本研究共纳入152名患者和271个病变。两人法组息肉切除术的平均手术时间明显短于普通手术组(中位时间:3.38 分钟与6.56 分钟p < 0.001)。此外,两人方法组息肉的IRR显著低于单人方法组(2/56,3.6%对47/215,21.9%;p = 0.001)。两人法组中没有一名患者出现延迟出血。结论 EMR的两人方法比单人方法更有效。因此,这种方法可能在未来取代传统的单算子方法。
