      【摘要】 目的 观察经内镜黏膜下剥离术(ESD)与黏膜切除术(EMR)治疗胃早期病变的临床疗效。方法 对
内镜及病理确诊为早期胃癌及高级别上皮内瘤变的患者进行EMR(39例)和ESD(45例)治疗,分别对其整块切
除、完全和不完全切除、手术时间、术中和术后出血、穿孔、复发率等进行统计,利用卡方检验对两者的疗效进行
统计分析。结果 (1)在未伴发溃疡的情况下,不论病灶大小,ESD组整块切除率和完全切除率均明显高于EMR
组(P<0.01),在伴发溃疡的情况下,不论病灶大小,组间差异无统计学意义(P>0.05);(2)不论病灶大小及是否伴
发溃疡,ESD组的平均手术时间均远长于EMR组(P<0.05),且ESD组的术中出血率明显高于EMR组(P<0.05),
但术后出血率组间差异无统计学意义(P>0.05);只有在伴发溃疡的情况下,ESD发生穿孔的风险性才高于EMR
组(P<0.05);(3)ESD组术后患者均无局部复发,而EMR组术后患者分次切除病变局部复发率明显高于整块切除
(P<0.05)。结论 ESD在治疗胃早期病变中整块切除和组织完全切除率明显高于EMR,且术后几乎无复发。但
ESD操作时间较长,术中存在较高的穿孔、出血风险性。

      【Abstract】 Objective To investigate the effect of endoscopic submucosal dissection (ESD) and endoscopic muco-
sal resection (EMR) in the treatment of early gastric cancer. Methods EMR (39 patients, EMR group) or ESD (45 pa-
tients, ESD group) was performed on patients who were diagnosed as early gastric cancer (EGC) with cervical intraepitheli-
al neoplasia. The en bloc resection rate, incomplete and complete resection rate, operation duration, intraoperative and post-
operative bleeding, perforation, and recurrence rate were studied and analyzed by the χ2 test. Results (1) In patients with-
out ulceration, the en bloc resection rate and complete resection rate were significantly higher in ESD group than EMR
group (P<0.01), regardless of tumor size, which showed no statistically significant difference between the two groups for pa-
tients complicated with ulceration (P>0.05). (2) In patients without ulceration, the average operation duration was signifi-
cantly longer in ESD group (P<0.05) regardless of tumor size, and the incidence of intraoperative bleeding was significantly
higher (P<0.05), but the incidence of postoperative bleeding showed no statistically significant difference between the two
groups (P>0.05). In patients with ulceration, the incidence of perforation was significantly higher in ESD group than EMR
group (P<0.05). (3) In EMR group, local recurrences by en bloc resection was significantly higher than that by incomplete
resection (P<0.05). No patient experienced recurrence in ESD group. Conclusion ESD can increase the en bloc and histo-
logically complete resection rate and reduce the local recurrence rate, but resulting in increased operation duration, higher
risk of perforation and bleeding during and after the treatment, compared with EMR.
