鼻内窥镜手术中避免窥口鼻道复合体粘连和闭塞的认识

目的：探讨鼻内窥镜手术中窥口鼻道复合体粘连和闭塞的原因和防治方法。方法：对本科完成的鼻内窥镜手术266例511例，进行随访检查，重点观察窦口鼻道复合体粘连和闭塞的情况。结果：术后出现术腔粘连124侧，其中中鼻甲与鼻腔外侧壁粘连106侧，中鼻甲与下鼻甲粘连65例；发现术腔闭塞62例。结论：窦口鼻道复合体粘连和闭塞的主要原因是钩突切除不完整、过份强调保留病变的中鼻甲和过多地损伤中鼻甲基板以及术后未能在鼻内窥镜下及时清除术腔复发的病变组织。     

内镜下尼龙绳套扎治疗消化道隆起性病变--附49例报告

目的:探讨内镜下尼龙绳套扎治疗宽基底或粗蒂消化道隆起性病变的临床疗效.方法:采用内镜下尼龙绳套扎法对49例宽基底或粗蒂消化道隆起性病变进行套扎,观察其疗效.结果:49例53枚消化道宽基底或粗蒂隆起性病变均一次性套扎成功,其中12例同时加行高频电凝切除;术后45例复查37例隆起性病变完全脱落消失(含已电凝切除者),7例部分脱落,1例未脱落;4例失访.1例同时加行高频电凝切除后并创面小动脉出血.治愈37例(82％)、有效7例(16％)、无效1例(2％).结论:尼龙绳套扎法对宽基底或粗蒂消化道隆起性病变的治疗效果满意,是一种安全、有效、经济、操作简便的方法,值得推广.     

胃Dieulafoy病的内镜诊断和治疗

目的：探讨胃Dieulafoy病的内镜诊断和治疗方法。方法：回顾性分析作者自1994年1月～2002年6月经内镜诊断和治疗胃Dieulafoy病的临床资料。结果：12例均在入院后2h之内行急诊内镜检查，经一次检查确诊10例．二次检查确诊2例。经内镜局部喷洒0．1％去甲肾上腺素治疗博动性出血3例，仅1例暂时止血约12h后再出血。电凝治疗11例均止血成功。结论：急诊内镜是诊断胃Dieulafoy病的最佳手段，浅表溃烂伴博动性或喷射状出血是内镜诊断的主要依据，单独的暗红色血痂或黑褐小隆起是内镜诊断的重要线索。经内镜局部喷洒止血药疗效不佳，电凝是治疗该病的有效手段。     

不同年龄组大肠息肉检出率及临床内镜的相关性研究

目的:探讨不同年龄组大肠息肉检出率、临床、内镜特点及与癌变的关系。方法:按年龄分为青年组(≤35岁),中年组(36～59岁),老年组(≥60岁)。比较不同年龄组大肠息肉患者的临床表现、镜下表现、病理类型,对其中老年组的80例进行1～5a(平均3.5a)的结肠镜随访,并与青中年组的138例患者相对照。结果:青年组大肠息肉的检出率、癌变率均明显低于老年组及中年组,随年龄增长检出率有逐渐增加的趋势;分布以直肠和乙状结肠多见;病理类型以腺瘤性息肉为多;息肉基底宽、体积大、数量多,癌变率高。结论:大肠息肉以老年组多见,腺瘤性息肉的大小、形态、数量及病理类型是癌变的主要危险因素,大肠息肉者尽可能镜下摘除,定期随访,减少癌变机会。     

鼻内窥镜下两种方法治疗鼻出血的疗效比较

目的：探讨鼻内窥镜下鼻出血的两种治疗方法的疗效：射频治疗法和止血材料填塞法。方法：比较分析从1999年8月～2002年7月经治的64例鼻出血患者的临床资料。结果：在鼻内窥镜下以射频治疗鼻出血。止血确切。免除鼻腔填塞。患者无痛苦。再出血率9．37％；以止血材料填塞治疗鼻出血。止血迅速。但患者填塞后有头痛及鼻胀感。并影响鼻窦通气引流。再出血率31．25％。结论：鼻出血的治疗应尽量避免鼻腔填塞；鼻内窥镜下射频治疗鼻出血是一种良好的治疗方法。值得临床推广应用。     

内镜在治疗胆总管结石中的应用价值(附480例报道)

目的 :探讨经内镜括约肌切开术 (EST)和内镜乳头气囊扩张术 (EPBD)在治疗胆总管结石中的应用价值。方法 :经EST和EPBD共治疗各类型胆总管结石 480例 ,对 <8mm胆总管结石采用EPBD治疗 ,>9mm胆总管结石采用EST治疗。结果 :474/ 480例 (98.8% )ERC检查成功 ,46 8/ 474例 (98.7% )内镜取石治疗成功 ,总的并发症 2 .7%。结论 :EST和EPBD治疗胆总管结石安全、有效 ,并发症少 ,是目前治疗胆总管结石的重要手段     

Endoscopic pilonidal sinus treatment versus total excision with primary closure for sacrococcygeal pilonidal sinus disease in the pediatric population

Purpose

To evaluate the effectiveness and safety of Endoscopic Pilonidal Sinus Treatment (EPSiT) in the pediatric population and compare it with excision followed by primary closure (EPC) regarding intra- and postoperative outcomes.

Computer-assisted cystoscopy diagnosis of bladder cancer

Objectives

One of the most reliable methods for diagnosing bladder cancer is cystoscopy. Depending on the findings, this may be followed by a referral to a more experienced urologist or a biopsy and histological analysis of suspicious lesion. In this work, we explore whether computer-assisted triage of cystoscopy findings can identify low-risk lesions and reduce the number of referrals or biopsies, associated complications, and costs, although reducing subjectivity of the procedure and indicating when the risk of a lesion being malignant is minimal.

Are hemoglobin levels really lower in faecal immunochemical test positive patients with colorectal cancer?

Introduction

Faecal immunochemical test (FIT) is advocated in many colorectal cancer-screening programs. A positive FIT translates to the need for a colonoscopy. However, waiting times for diagnostic colonoscopy is long. The aim of our study is to determine the correlation of hemoglobin levels in patients with a positive FIT who were subsequently diagnosed with colorectal cancer, and to compare them with patients with only colonic adenomas and those with normal colonoscopy with the intention of determining if hemoglobin levels could be used to stratify the urgency of colonoscopy.
