内镜下高频电息肉摘除术治疗大肠息肉146例

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

Follow-up colonoscopy in patients with colorectal adenomatous polyps

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.     

结直肠腺瘤切除术后复发息肉的特点分析

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.     

喉罩辅助通气气管镜介入治疗高位气管息肉一例

气管息肉是由于气管黏膜受到机械刺激、炎症感染等引发。目前随着各级医院人工气道技术普遍开展,其发生率越来越高。气管息肉缺乏特异性临床表现,易引起误诊。本文报道兰州大学第二医院呼吸内科收治的1例高位气管息肉患者,并分析其发病及诊治过程,以提高临床医师对该病的认识和处理水平。     

结直肠息肉癌变的内镜下表现、治疗及癌变因素分析

目的探讨结直肠息肉癌变的内镜下表现,分析癌变相关因素和治疗策略。方法回顾性分析经电子结肠镜检查或治疗的77例结直肠癌变息肉患者的临床、内镜及病理资料,探讨影响结直肠息肉癌变的相关因素及其内镜下治疗策略。结果77例癌变结直肠息肉中,9例伴发结肠癌。60例有临床症状,症状发生率为77．9％（60／77）。息肉癌变主要分布在乙状结肠,多发生于年龄超过60岁的老年患者,绒毛状腺瘤癌变率最高。行电子结肠镜电切法切除44例,其中完全切除38例。结论年龄〉60岁患者和乙状结肠息肉癌变发生率明显增高,选择性对属于原位癌或早期浸润癌的癌变息肉行电子结肠镜下切除是安全有效的。     

Endoscopic management of large colorectal polyps

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.

Conventional colonoscopy and magnified chromoendoscopy for the endoscopic histological prediction of diminutive colorectal polyps： A single operator study

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.     

Role of high definition colonoscopy in colorectal adenomatous polyp detection

结直肠侧向发育型肿瘤并发结直肠息肉的预测因子及发生恶变的危险因素

目的探究结直肠侧向发育型肿瘤(colorectal laterally spreading tumors, CLST)并发结直肠息肉的独立预测因子及CLST合并结直肠息肉发生恶变的独立危险因素。方法回顾性收集2016年1月—2021年12月在大连医科大学附属第二医院行内镜检查发现CLST, 并接受内镜下治疗的260例患者的临床资料。根据是否与结直肠息肉共存将CLST患者分为共存组(n=135)与非共存组(n=125), 比较两组的临床病理特征差异, 采用二元Logistic回归分析共存现象的预测因子。根据共存组CLST的浸润深度, 将共存组分为共存恶性组(n=38)与共存非恶性组(n=97), 采用二元Logistic回归分析CLST合并结直肠息肉发生恶性变的危险因素。结果男性(P=0.002, OR=2.355, 95%CI:1.354～4.099)、绒毛管状腺瘤(P=0.022, OR=3.873, 95%CI:1.214～12.355)、既往有息肉病史(P=0.001, OR=2.738, 95%CI:1.527～4.909)是CLST合并结直肠息肉的独立危险因素。该预测模型受试...
