Patients with Gastric Antral Vascular Ectasia (GAVE) Are at a Higher Risk of Gastrointestinal Bleeding in the Absence of Cirrhosis

Background and Aims: Gastric antral vascular ectasia (GAVE) is commonly found in patients with cirrhosis, but it is also associated with other diseases in the absence of cirrhosis. Whether GAVE confers a different severity of gastrointestinal (GI) bleeding between patients with and without cirrhosis remains unknown. We aim to examine whether there is a difference in clinically significant GI bleeding due to GAVE in patients with or without cirrhosis. Methods: This is a retrospective case-control study of patients who were diagnosed with GAVE between January 2000 and June 2014. Patients were categorized into cirrhosis and noncirrhosis groups, and those with an additional GI bleeding source were excluded. Univariate comparisons and multivariable models were constructed using logistic regression. Results: In total, 110 patients diagnosed with GAVE on esophagogastroduodenoscopy (EGD) were included in our analysis; 84 patients had cirrhosis (76.4%) and 26 (23.6%) did not. Active GI bleeding was more prevalent in patients without cirrhosis (63.4% vs. 32.1%, p=0.003) despite similar indications for EGD, and endoscopic treatment with argon plasma coagulation (APC) was required more often in this group, approaching statistical significance (27% vs. 10.7%, p=0.056). There was no difference in bleeding severity, as evidenced by similar re-bleeding rates, surgery, or death attributed to uncontrolled bleeding. The strongest independent risk factor for GI bleeding was the absence of cirrhosis (odds ratio (OR): 5.151 (95% confidence interval (CI): 1.08-24.48, p=0.039). Conclusions: Patients with GAVE in the absence of cirrhosis are at higher risk for active GI bleeding and require more frequent endoscopic treatment than similar patients with cirrhosis. It may be worthwhile to treat GAVE in this population even in the absence of active bleeding.     

Barrett食管及相关并发症的X线探讨

目的:通过16例经内窥镜及病理证实为Barrett食管的钡餐检查表现,初步探讨Barrett食管及其并发症放射学检查的意义。方法:回顾性分析16例Barrett食管的内窥镜和气钡检查的记录及表现,着重探讨气钡检查的X线表现。结果:食管内窥镜和组织学检查全部病例均有炎症改变,其他可见胃食管反流、食管溃疡和食管腺癌。放射学钡餐检查结果:Barrett食管炎4例,Barrett食管溃疡7例,Barrett食管癌5例。结论:Barrett食管及其并发症至今无明确放射学征象,改进对“Z”线的检查技术和方法,有可能提高其发现率。钡餐发现胃食管反流、食管裂孔疝同时并发食管炎、食管溃疡及食管癌者均应考虑到本症的可能。     

The relationship between interstitial cystitis and endometriosis in patients with chronic pelvic pain.

OBJECTIVE: This study was designed to determine the relationship between interstitial cystitis (IC), endometriosis (endo), and chronic pelvic pain (CPP) in individuals in whom nongynecological and nonurological problems had been previously ruled out. METHODS: A prospective study of 162 consecutive women with a complaint of chronic pelvic pain seen in the clinic was performed between August 2002 and December 2005. These patients underwent a workup to exclude other causes of pelvic pain, had PUF (Pain Urgency and Frequency) questionnaires filled out, and underwent a laparoscopy and a cystoscopy with hydrodistention. Pain levels were determined, and treatment was reviewed and enumerated. Results were obtained and quantified. RESULTS: In this study, 123 (76%) patients were diagnosed with active endometriosis, 133 (82%) were diagnosed with interstitial cystitis, and 107 (66%) had both disease entities simultaneously. Thirteen (8%) patients were diagnosed with pathologies unrelated to endometriosis and interstitial cystitis. Pain levels were seen to decrease at 6 months in all groups of patients with the exception of those patients with endometriosis only. CONCLUSION: CPP is a difficult, taxing, and frustrating concern for many women in the United States. These individuals have traditionally been difficult to treat. A large number of women with CPP in our patient population have been shown to have endometriosis, interstitial cystitis, or both. Therefore, a workup for premenopausal individuals with CPP involves obtaining a history that keys into possible nongynecologic causes of pain, a complete accounting of urinary problems, and a thorough history of gynecological problems. A physical examination with a comprehensive history should be performed, and the investigation may include the possibility of a simultaneous laparoscopy and cystoscopy if warranted. These procedures can serve as both a means for diagnosis and treatment of these problems when encountered.     

神经导航内窥镜辅助下单鼻孔入路垂体腺瘤切除

目的神经导航、内窥镜辅助下垂体腺瘤的经单鼻孔经蝶手术治疗。方法对6例经磁共振成像诊断垂体腺瘤的病人术前进行磁共振成像定位,将影像资料输入导航工作站,作术前手术计划。采用零度及45度镜经单鼻腔,在导航的动态指引下确认鞍底,于内窥镜下实施瘤实质切除。结果本组5例完全切除,1例因为瘤实质较韧而作大部分切除,术后病人的视力均得到了改善。导航预期误差1.48mm,实际误差1.8mm。结论神经导航引导下的经鼻蝶垂体腺瘤手术定位准确,内窥镜下操作对鼻腔的解剖结构影响小、组织损伤轻,病人恢复快。     

CT结合内镜检查诊断胃肠道间质瘤的价值

目的：探讨CT结合内镜检查诊断胃肠道间质瘤(GIST)的价值。方法：回顾分析18例均经手术病理检验证实为GIST病人的CT及内镜检查资料。结果：(1)18例GIST的CT表现为类圆形或分叶状肿瘤，边界清楚，13例平扫及增强密度均匀，强化明显，5例瘤灶内有坏死液化区；肿瘤周围肠管不同程度受压移位或粘连。(2)15例源于胃、十二指肠及结肠的间质瘤均行内镜检查，4例瘤侧胃壁镜下所见黏膜呈外压性改变者未行咬检；11例伴有溃疡形成，溃疡处咬检获取病理组织。(3)18例均行手术后光镜观察及免疫组化检查，18例CD-117均为阳性，13例CD-34阳性，10例Vimentin阳性。结论：CT与内镜相结合检查，能提高胃、十二指肠及结肠GIST定位、定性的准确性。     

经尿道手术治疗尿道狭窄与闭锁(附364例报告)

目的 提高经尿道手术治疗尿道狭窄与闭锁的成功率。方法 总结364例经尿道手术治疗尿道狭窄与闭锁的经验。患者平均年龄43岁。病程1个月～23年。尿道狭窄与闭锁长度平均2．2cm。结果 364例中手术成功343例(94．23%)，其中一次成功290例，二次手术成功34例，三次手术18例，四次手术1例；手术失败21例，其中20例改为开放手术，失败原因主要为骨盆骨折致尿道错位成角，骨片压迫尿道。术后268例随访4～138个月，平均34个月。17例感染性尿道狭窄者及29例骨盆骨折后尿道狭窄者术后曾需短期尿道扩张，其余排尿通畅。结论经尿道手术治疗尿道狭窄与闭锁安全、有效，是尿道狭窄与闭锁的首选治疗方法。术后尿道扩张是防止再狭窄的重要手段．     

假性胰腺囊肿的内窥镜治疗

目的 探讨假性胰腺囊肿内窥镜治疗的适应证、手术效果、并发症及优缺点。方法 对假性胰腺囊肿内窥镜治疗的相关文献进行综述。结果 内窥镜技术具有创伤小、操作方便、可反复进行等特点，其适应证正不断扩大．除内窥镜治疗失败、囊肿合并并发症和多发性囊肿时考虑外科手术外，其他情况下假性胰腺囊肿的治疗可考虑内窥镜优先的策略。结论 假性胰腺囊肿的治疗应根据囊肿大小、数量、解剖学部位及有无并发症等综合因素实行个体化原则。
