Lingual lymph nodes: Anatomy,clinical considerations,and oncological significance

Lingual lymph nodes are an inconstant group of in-transit nodes, which are located on the route of lymph drainage from the tongue mucosa to the regional nodes in neck levels I and II. There is growing academic data on the metastatic spread of oral cancer, particularly regarding the spreading of oral tongue squamous cell carcinoma to lingual nodes. These nodes are not currently included in diagnostic and treatment protocols for oral tongue cancer. Combined information on surgical anatomy, clinical observations, means of detection, and prognostic value is presented. Anatomically obtained incidence of lingual nodes ranges from 8.6% to 30.2%. Incidence of lingual lymph node metastasis ranges from 1.3% to 17.1%. It is clear that lymph nodes that bear intervening tissues from the floor of the mouth should be removed to improve loco-regional control. Extended resection volume, which is required for the surgical treatment of lingual node metastasis, cannot be implied to every tongue cancer patient. As these lesions significantly influence prognosis, special efforts of their detection must be made. Reasonably, every tongue cancer patient must be investigated for the existence of lingual lymph node metastasis. Lymphographic tracing methods, which are currently implied for sentinel lymph node biopsies, may improve the detection of lingual lymph nodes.     

敷料更换的不同次数对穿刺引流术后穿刺口感染的影响

目的 研究敷料更换的不同次数对穿刺引流术后穿刺口感染的影响.方法 随机将该院2013年6月—2014年7月收治的100位进行穿刺引流术的患者分为两组,50例为A组,50例为B组. 为A组患者1周更换1次敷料,B组患者1周更换2次敷料. 对两组患者穿刺口感染的情况进行分析比较. 结果 A组患者穿刺口感染的几率显著低于B组(P<0.05),A组患者的病原菌定植率显著低于B组(P<0.05),两组患者导管相关性血流感染率差异无统计学意义(P>0.05). 结论 穿刺引流术后的患者1周更换1次敷料比较合理,既能降低患者术后穿刺口感染的几率,又能降低医护人员的工作量,但要注意在敷料发生松动或者潮湿时也要及时进行更换.     

改良切开引流术治疗直肠壁内脓肿

目的:探讨改良切开引流术治疗直肠壁内脓肿的临床效果。方法:将32例直肠壁内脓肿患者随机分为改良切开引流术(治疗组)和传统切开引流术(对照组)治疗,每组16例,对比观察两组治愈率、创面愈合时间、肛门功能状况、术后复发以及术后并发症情况。结果:治疗组与对照组比较,治疗组治愈率高100%,(P<0·05);创面愈合时间短(17·3±2·5)d,P<0·01;但肛门功能、术后复发及术后并发症两组差异无统计学意义(P>0·05)。结论:改良切开引流术在治疗直肠壁内脓肿方面明显优于传统手术。     

自发性气胸的临床特点与治疗对策

目的通过对多种自发性气胸的临床表现采用不同的治疗方法,达到治愈。方法根据不同临床表现及气胸压缩程度采取人工抽气、闭式引流术、胸膜粘连术等检测效果。结论96例病人中治愈90例,说明采用适用的方法可有效地治疗自发性气胸。     

B超引导下穿刺置管引流术治疗肝脓肿 92例临床分析

目的探讨肝脓肿在超声引导下穿刺置管引流术对肝脓肿治疗的疗效.方法回顾性分析1998年3月～2004年3月,92例肝脓肿病人的临床资料.结果本组92例病人共进行102次穿刺置管引流术,总治愈率为96.63%,平均疗程19天(8～30天).术后无腹腔内出血、气胸、脓胸及严重腹腔感染等并发症.治疗效果满意.结论B超引导下肝脓肿穿刺置管引流术具有简便、安全、住院时间短、费用少,并发症低的优点,可用于治疗大多数肝脓肿.     

ENDOSCOPIC NASOBILIARY DRAINAGE: CURRENT INDICATIONS AND EVALUATION OF THE PRODUCTS

Endoscopic nasobiliary drainage (ENBD) is a well established mode of biliary decompression. Although ENBD is certainly an uncomfortable procedure with the potential risk of spontaneous dislocation or removal of the drainage catheter by disoriented patients, it has several advantages over endoscopic biliary drainage (EBD) using an indwelling stent. The current indications for ENBD are: (i) temporary drainage to treat obstructive jaundice and cholangitis caused by malignant or benign biliary stricture; (ii) urgent drainage to treat suppurative cholangitis primarily caused by common bile duct stones; (iii) temporary drainage after stone removal in patients with suspected incomplete clearance and/or with cholangitis; and (iv) biliary leaks that occur primarily after surgery, as well as other indications. Different types of nasobiliary catheters are currently available that have been designed with various diameters, shapes, and materials. However, the current catheters are not considered by most endoscopists to be sufficient. Further improvements are needed to achieve better drainage and better maneuverability.
