将绒毛腺瘤作为癌来处理。关于腺瘤癌变的时间,一般平均10年左右,亦有短至数月者,我们认为一旦发现息肉即应摘除。由于腺瘤性息肉的复发率达39%,因此术后密切随访尤为重要。我们认为对腺瘤性息肉伴不典型增生者,应于术后3~6个月复查,以后可每隔1年复查1次,如无新的病变,可延长至每2~3年复查1次内镜下高频电息肉摘除术治疗大肠息肉146例@辛洪波$济南市槐荫区人民医院!250021@姜甦$济南市槐荫区人民医院!250021@陈忠$济南市槐荫区人民医院!250021 相似文献

Forty-four asymptomatic patients with adenomatous colorectal polyps were followed by repeated colonoscopies and subsequent
removal of new polyps. The median follow-up time was 34 months (range, 4 to 131 months). Twenty-six patients (59 percent)
developed new adenomatous polyps. Therecurrence rate was 69 percent in patients with multiple polyps compared with 54 percent
in patients with a single polyp. The location of new polyps was in the same colonic segment in 81 percent of the patients,
but not at the same site in the colon where a previous polyp had been removed. The histopathology and size of new polyps compared
with the initial polyps showed a significant improvement in histopathology toward more benign polyps (P<0.02) and smaller polyps (P<0.001). In patients who initially had single adenomatous polyps, new polyp(s) were diagnosed after a mean time of 23 months
compared initially. Patients with atypia in initial polyp(s) developed new polyp(s) after a mean time of 11 months compared
with 23 months in patients without atypia. The mean time from a colon with no polyps to the diagnosis of a new adenomatous
polyp less than 5 mm in size was 11.5 months, which was a statistically significant shorter time than the 19.4 months observed
for the development of polyps 5 mm or larger. 相似文献

目的 研究结直肠腺瘤(colorectal adenoma,CRA)切除术后复发息肉的特点.方法 收集2005年5月-2012年5月于首都医科大学附属北京朝阳医院消化内科完成结肠镜下息肉切除术、病理组织学确诊为CRA,术后行肠镜复查,并发现复发息肉的患者103例.统计分析初发息肉的大小、数目、病理分型、发生部位、肠镜间隔时间与复发息肉的大小、数目、病理分型、发生部位之间的关系.结果 93%的患者复发息肉大小都在1 cm以内;复发息肉在左半结肠占65%,在右半结肠占12%,在全结肠占22%;初检CRA大小、数目、病理分级与复发息肉的大小、数目、病理分级,经统计分析均无关联,初检发生部位与复发息肉的发生部位有相关性(P<0.05).结论 复发息肉通常是多发、较小、低危的,虽然大部分在第1年已经出现,但在5年之内其镜下特点及病理分型均无统计学意义.初检位于左半结肠的CRA患者,复发息肉更易在左半结肠,而初检位于全结肠的患者复发息肉更易在全结肠. 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

AIM: To accurately differentiate the adenomatous from the non-adenomatous polyps by colonoscopy. METHODS: All lesions detected by colonoscopy were first diagnosed using the conventional view followed by chromoendoscopy with magnification. The diagnosis at each step was recorded consecutively. All polyps were completely removed endoscopically for histological evaluation. The accuracy rate of each type of endoscopic diagnosis was evaluated, using histological findings as gold standard. RESULTS: A total of 240 lesions were identified, of which 158 (65.8%) were non-neoplastic and 82 (34.2%) were adenomatous. The overall diagnostic accuracy of conventional view, and chromoendoscopy with magnification was 76.3% (183/240) and 95.4% (229/240), respectively (P< 0.001) CONCLUSION: The combination of colonoscopy and magnified chromoendoscopy is the most reliable non-biopsy method for distinguishing the non-neoplastic from the neoplastic lesions. 相似文献
