目的探讨采用内镜黏膜下剥离术(ESD)治疗结直肠侧向发育型息肉的应用价值。 方法回顾性分析2018年1月至2019年12月经内蒙古消化病研究所内镜中心行肠镜检查发现的45例结直肠侧向发育型息肉患者,应用IT刀、Hook刀行ESD治疗。将ESD成功率、剥离病变大小、手术时间、手术并发症及复发率等纳入观察范围。 结果45例结直肠病变接受ESD,其中,2例病变黏膜下注射后病变托举差,术中剥离困难且容易出血转外科手术。术后病理证实,3例癌变且基底仍有肿瘤残留,行外科手术扩大切除。ESD成功率88.9%(40/45)。病变直径为1.5~6.3 cm,平均3.6 cm;ESD手术时间为31~125 min,平均67 min。3例术后有便血,其中1例保守治疗失败,内镜下成功电凝止血,ESD术后出血发生率7%(3/43)。4例在ESD治疗中有小穿孔,应用软组织夹成功缝合穿孔,未转开腹手术,ESD穿孔发生率为9.3%(4/43)。术后40例患者均随访,创面基本愈合,无病变残留和复发。 结论ESD治疗结直肠侧向发育型息肉疗效可靠,能完整切除较大的病变,提供完整的病理学资料且复发率低。出血和穿孔是其主要的短期并发症。  相似文献

AIM:To investigate the risk factors for delayed bleeding following endoscopic submucosal dissection(ESD)treatment for colorectal neoplasms.METHODS:We retrospectively reviewed the medical records of 317 consecutive patients with 325 lesions who underwent ESD for superficial colorectal neoplasms at our hospital from January 2009 to June2013.Delayed post-ESD bleeding was defined as bleeding that resulted in overt hematochezia 6 h to 30d after ESD and the observation of bleeding spots as confirmed by repeat colonoscopy or a required blood transfusion.We analyzed the relationship between risk factors for delayed bleeding following ESD and the following factors using univariate and multivariate analyses:age,gender,presence of comorbidities,use of antithrombotic drugs,use of intravenous heparin,resected specimen size,lesion size,lesion location,lesion morphology,lesion histology,the device used,procedure time,and the presence of significant bleeding during ESD.RESULTS:Delayed post-ESD bleeding was found in14 lesions from 14 patients(4.3%of all specimens,4.4%patients).Patients with episodes of delayed postESD bleeding had a mean hemoglobin decrease of2.35 g/dL.All episodes were treated successfully using endoscopic hemostatic clips.Emergency surgery was not required in any of the cases.Blood transfusion was needed in 1 patient(0.3%).Univariate analysis revealed that lesions located in the cecum(P=0.012)and the presence of significant bleeding during ESD(P=0.024)were significantly associated with delayed post-ESD bleeding.The risk of delayed bleeding was higher for larger lesion sizes,but this trend was not statistically significant.Multivariate analysis revealed that lesions located in the cecum(OR=7.26,95%CI:1.99-26.55,P=0.003)and the presence of significant bleeding during ESD(OR=16.41,95%CI:2.60-103.68,P=0.003)were independent risk factors for delayed post-ESD bleeding.CONCLUSION:Location in the cecum and significant bleeding during ESD predispose patients to delayed post-procedural bleeding.Therefore,careful and additional management is recommended for these patients.  相似文献

Background and study aims

Endoscopic submucosal dissection (ESD), a minimally invasive treatment for early gastrointestinal (GI) cancer, is considered challenging and risky in the colorectum. As such, most patients undergoing ESD are hospitalized due to the perceived increased risk of adverse events. The aim of this study was to compare the costs, safety and efficacy of colorectal-ESD in an outpatient vs inpatient setting in a tertiary level center.

Methods

This is a retrospective study on consecutive patients admitted for colorectal-ESD. Patients were divided into outpatients (Group-A, same-day discharge), and inpatients (Group-B, admitted for at least one night). Data on overall costs, outcomes and adverse events were assessed for each group.

Results

A total of 136 patients were considered. Fourteen were excluded because ESD was not performed due to intraprocedural suspicion of invasive cancer. Eighty-three patients were treated as outpatients (Group-A, 68%) and 39 (Group-B, 32%) were hospitalized. R0-rate was 90.4% in Group-A and 89.7% in Group-B(P?=?0.98). One perforation occurred in Group-A (1.2%) and 2 in Group-B(5.1%, P?=?0.2). Mean Length of stay (LOS) was 1?day for outpatients and 3.3?days for inpatients. Management of Group-A as outpatients produced a cost savings of 941€ on average per patient.

Conclusions

Outpatient colorectal-ESD is a feasible, cost-effective strategy to manage superficial colorectal tumors with outcomes comparable to inpatient colorectal-ESD. By using proper selection criteria, outpatient ESD could be considered the first-line approach for most patients.  相似文献

Although endoscopic submucosal dissection (ESD) gains acceptance as one of the standard treatments for esophageal and stomach neoplasms in Japan, it is still in the developing stage for colorectal neoplasms. In terms of indications, little likelihood of nodal metastasis and technical resectability are principally considered. Some of intramucosal neoplasms, carcinomas with minute submucosal invasion, and carcinoid tumors, which are technically unresectable by conventional endoscopic treatments, may become good candidates for ESD, considering substantial risks and obtained benefits. ESD as a staging measure to obtain histological information of the invasion depth and lymphovascular infiltration is acceptable because preoperative prediction is difficult in some cases. In terms of techniques, advantages of ESD in comparison with other endoscopic treatments are to be controllable in size and shape, and to be resectable even in large and fibrotic neoplasms. The disadvantages may be longer procedure time, heavier bleeding, and higher possibility of perforation. However, owing to refinement of the techniques, invention of devices, and the learning curve, acceptable technical safety has been achieved. Colorectal ESD is very promising and become one of the standard treatments for colorectal neoplasms in the near future.  相似文献

Background and aim

The histologic discrepancies between preoperative endoscopic forceps biopsy (EFB) and endoscopic submucosal dissection (ESD) specimens sometimes confuse the endoscope operator. This study aimed to analyze the limitation of the biopsy-based diagnosis before ESD and to evaluate which factors affect the discordant pathologic results between EFB and ESD.

Methods

A total of 1427 patients, who were diagnosed with gastric adenoma by EFB, were enrolled. Cancer confirmed on EFB was excluded (n?=?513). We retrospectively reviewed cases and compared histologic diagnoses in the biopsy sample with the final diagnosis in the endoscopically resected specimen.

Results

The diagnosis was upgraded (from low-grade dysplasia to high-grade dysplasia or adenocarcinoma, or from high-grade dysplasia to adenocarcinoma) in 328 cases (23.0%), concordant in 944 (66.1%), and downgraded (from high-grade dysplasia to low-grade dysplasia or non-neoplasia, or from low-grade dysplasia to non-neoplasia) in 155 (10.9%). Multivariate logistic regression analysis showed that surface ulceration and depressed lesions were associated with significant risk factors for upgrading. Age younger than 60 years and size <1?cm were associated with significant factors for downgrading.

Conclusions

Careful endoscopic observation should consider size, ulceration, and depression to ensure accurate diagnosis when a gastric neoplasm is suspected.  相似文献

目的 研究结直肠侧向发育型肿瘤(LST)各亚型相关的临床病理学特点以及内镜黏膜下剥离术( ESD)治疗的疗效与安全性.方法 对经ESD治疗的174例结直肠LST病变的临床病理资料进行回顾性分析.先按内镜下表面形态将LST分为4个亚型,然后对各亚型的临床病理特点以及ESD治疗的切除率、操作时间、并发症和复发情况等进行分析.结果 在颗粒型(LST-G)病变中,结节混合型的病变大小[(35.3±14.2)mm]、高级别上皮内瘤变及黏膜下癌的发生率(51.0%)、操作时间[(52.1±33.0)min)]均明显大于颗粒均一亚型;而非颗粒型(LST-NG)的伪凹陷型的病变大小[(30.1±9.1)mm]、黏膜下癌的发生率(11.1%)和操作时间[(62.7±31.0) min]均明显大于扁平隆起型.LST-G与LST-NG及各亚型之间整块切除率、完整切除率及完整治愈切除率差异均无统计学意义.LST-G的颗粒均一型及LST-NG的扁平隆起型无明显并发症发生,结节混合型术后出血率为4.6%,穿孔率为3.5%;伪凹陷型术后出血率和穿孔率均为11.1%.1例伪凹陷型在术后第6个月复查发现复发.结论 结节混合型和伪凹陷型由于病变较大、黏膜下侵犯的概率高,所需操作时间较长,并发症发生率较高,应由操作技术高者来完成.无论是临床治疗还是基础研究,准确区分这4种亚型是很有必要的.  相似文献
