随着医疗技术的不断发展,纤维胃镜在临床上的应用日益广泛。套扎术是以治疗内痔的弹性橡皮环结扎原理为基础的治疗方法,并在食管静脉曲张治疗中取得了令人满意的疗效。上消化道息肉是最常见的一种良性肿瘤,组织学上分为增生性息肉和腺瘤性息肉。有些恶变早期的腺瘤样息肉病灶小、浅,很少浸润。而内镜下取材有局限性,不能反映全部息肉状态而易漏诊,故应早期行内镜下息肉套扎术。本院应用日本GIFXQ30纤维胃镜,圈套器及橡胶圈为天津市天医医用硅胶品厂生产,并已对16例病人进行了检查和治疗,现分析总结于下。1 临床资料与方法本组男11例,… 相似文献

目的评估金属夹及尼龙圈套在预防结肠粗蒂息肉切除术后出血的效果。
方法选择2015年8月至2018年8月经海军军医大学附属长海医院虹口院区消化内科就诊,息肉顶部直径>10 mm同时蒂部直径>5 mm的息肉患者85例为研究对象。根据息肉预处理方法的不同分为预先金属夹夹闭组(A组)和预先金属夹联合尼龙圈套套扎组(B组)。回顾性分析每组患者息肉形态、部位、大小、病理类型及术中,术后出血发生率、金属夹使用数量、息肉残留率、息肉复发率等指标。
结果A组和B组息肉形态以山田Ⅲ、Ⅳ型为主,主要位于直肠和乙状结肠,两组患者性别、年龄、息肉顶部、蒂部平均直径相比均无明显差异(P>0.05)。A组和B组的术中出血发生率(6.4%对0,P>0.05)、术后迟发性出血发生率(1.6%对2%,P<0.05),术中和术后迟发性出血均经内镜治疗后停止。A组3例患者术后3个月息肉基底部残留;B组患者术后3个月手术创面良好,息肉基底部无残留,息肉无复发。
结论对于蒂部直径超过5 mm的粗蒂息肉,预先使用金属夹和尼龙圈套可有效预防息肉切除术后出血,是否联合使用需要根据蒂的长短和直径具体决定。 相似文献

Management of Colonic Dieulafoy Lesions With Endoscopic Mechanical Techniques: Report of Two Cases 总被引:4,自引:0,他引:4

Although Dieulafoy lesion is generally located in the proximal stomach, other locations have been reported. We present two cases of bleeding colonic Dieulafoy in patients with chronic renal failure who were treated with mechanical methods. In the first case, an active arterial bleeding without mucosal defect was localized in the descending colon. In the second case, a protruding vessel with active bleeding was found in the transverse colon. The two patients were initially treated with epinephrine and hemostatic clips. In the second patient, an endoloop was attached to the base of the previously placed hemoclips because of rebleeding. To our knowledge, this is the first case of combined endoscopic approach with hemostatic clips and endoloop to treat a colonic Dieulafoy lesion. Colonic Dieulafoy lesions reported in the relevant literature and the hemostatic treatments used are reviewed.Supported in part by a grant from the Instituto de Salud Carlos III (C03/02). 相似文献

BACKGROUNDEndoscopic resection of non-invasive lesions is now the standard of care for lesions in the GI tract. However, resection techniques require extensive training, are not available in all endoscopy centers and are prone to complications. Endoscopic mucosal ablation (EMA) is a combination of resection and ablation techniques and it may offer an alternative in the management of such lesions.CASE SUMMARYIn this case series we report the successful treatment of three flat colonic polyps using the EMA technique. Two lesions were treatment naïve and 1 was a recurrence after an endoscopic mucosal resection. The sizes ranged from 2 to 4 cm. All three polyps were ablated successfully with no immediate or delayed complications. The recurrence rate at 1 year of follow up was 0%.CONCLUSIONBased on this initial experience, we conclude that EMA is a safe and effective technique for the treatment of non-invasive colonic polyps when endoscopic resection techniques are not available. 相似文献

Objectives The optimal treatment for large colorectal polyps (LCPs) is still a controversial issue. The aim of this study was to evaluate
the safety and effectiveness of endoscopic polypectomy (EP) of colorectal polyps ≥2 cm in size.
Patients and methods One hundred fifty-one EP LCPs were performed over a period of 7 years. Diathermal snare was used for pedunculated and pseudopedunculated
polyps and endoscopic mucosal resection (EMR) or biopsy forceps polypectomy for sessile and flat polyps. The resected polyps
were recovered and collected for histology. At scheduled follow-up visits 1, 3, 6, and 12 months after polypectomy, complications
and recurrences were recorded in all patients.
Results Fifteen polyps were located in the rectum, 84 in the sigmoid colon, 11 in the descending colon, four in the splenic flexure,
11 in the transverse colon, 11 in the hepatic flexure, seven in the ascending colon and eight in the cecum. Fifty-six polyps
were sessile, 54 pedunculated, 25 pseudopedunculated, and 16 flat. At histology, most of polyps (131) were adenomas (nine
with adenocarcinoma in situ). Five were invasive polypoid carcinomas and required colonic resection. Immediate bleeding occurred
in ten patients (7.6%) and it was stopped by endoscopic hemoclips (7), epinephrine injection (1), or surgery (2). There were
three perforations (2.3%; all polypoid carcinomas), managed endoscopically (1) or surgically (2). Delayed bleeding occurred
in two patients (1.5%) and was treated by endoscopic diathermy and hemoclips (1) or surgery (1). During follow-up, six (4.6%)
incompletely excised polyps and three (2.3%) relapses in the site of previous EP were detected and endoscopically removed.
Conclusion EP is relatively safe and effective for benign-appearing LCPs. 相似文献

Background and aims Issues on colonoscopy quality are crucial to reduce the advanced neoplasia miss rate of colonoscopy. Recently, a >6-min withdrawal
time has been recommended. However, the relative prevalence of polyp detected during insertion and withdrawal phases of colonoscopy
is unknown. Therefore, we designed this prospective, endoscopic study.
Materials and methods Three hundred and sixty-eight patients with 396 adenomas were selected from a consecutive colonoscopic series of 1,205 cases.
Detection rates of adenomas, advanced adenomas, and cancer according to withdrawal and insertion phases of colonoscopy, also
subgrouping polyps for size and location, were compared.
Results Thirty-two (74%) advanced adenomas and 21 (95%) cancers were detected during the insertion, being only 11 (26%) and one (5%)
identified during withdrawal, respectively. This was mainly due to a higher detection of >10 mm polyps during insertion than
during withdrawal (75% versus 25%).
Conclusions Most advanced neoplasia are detected during the insertion. Although withdrawal time has been shown to be important, the scope
insertion phase related to polyp detection should be specifically addressed. 相似文献

PURPOSE: The study was undertaken to evaluate the clinical usefulness of endoscopic transanal decompression with a newly developed drainage tube for the treatment of acute colonic obstruction. METHODS: Thirty-six patients ranging in age from 46 to 87 years (average age = 69 years) with acute colorectal obstruction secondary to carcinoma were treated by means of intubation with a flexible drainage tube using combined endoscopic and fluoroscopic guidance. After tube placement, the obstructed colon was aspirated, decompressed, and cleaned with a 50 ml syringe and saline solution. The drainage tube was kept inserted and the colon was irrigated two or three times per day using 500 to 1,000 ml of saline until there were no contents in the colon. The colon was almost empty at the time of operation. The success rate, benefits, and complications of this technique were evaluated. RESULTS: Placement of the drainage tube was successful in 34 (94.4 percent) of 36 patients. Immediately after aspiration and decompression, symptoms related to obstruction were relieved in 21 patients (61.8 percent), within one hour in 9 patients (26.5 percent) and within four hours in 4 patients (11.8 percent). All 34 patients had elective single-stage surgery without severe complications at the anastomotic site such as anastomotic leakage and postanastomotic stenosis that needed treatment a few days after placement of the drainage tube. In the two cases of unsuccessful placement of the drainage tube, emergent colostomy was performed. CONCLUSION: Decompression with a transanal drainage tube is an easy and safe technique to relieve colonic obstruction effectively without any excess burden to patients. Because the procedure permits single-stage surgery in most cases, it is also cost effective.Presented at the meeting of the Radiological Society of North America, Chicago, Illinois, November 27 to December 3, 1999. 相似文献
