Pentax has introduced the VSB-P2900 for endoscopic evaluation of the small bowel. This is a standard video upper endoscope lengthened to 250 cm. We report a case utilizing this instrument. A 65-yr-old white male was admitted with respiratory failure. Gastrointestinal bleeding developed. Upper endoscopy, colonoscopy, push enteroscopy, and mesenteric angiography were nondiagnostic. Enteroscopy to the proximal to mid ileum was performed. Approximately 90% of the intubated small bowel mucosa was visualized. An arteriovenous malformation and an ulcer were identified and cauterized. Time elapsed from intubation to extubation was 90 min, including two KUBs. No further bleeding was observed. The VSB-P2900 is likely to simplify examination of the small intestine. Tip control allows a large percentage of the intubated small bowel to be visualized. A working channel allows therapeutics. The technique is simple, fast, and within the skills of most endoscopists. A safety and efficacy profile need to be determined.
宾得公司推出了VSB - P2900用于小肠的内镜评估。这是一款延长至250厘米的标准视频上消化道内窥镜。我们报告了一例使用该器械的病例。一名65岁的白人男性因呼吸衰竭入院。随后出现了胃肠道出血。上消化道内镜检查、结肠镜检查、推进式小肠镜检查和肠系膜血管造影均未明确病因。对回肠近端至中段进行了小肠镜检查。约90%的插管小肠黏膜得以可视化。发现一处动静脉畸形和一个溃疡并进行了烧灼治疗。从插管到拔管的时间为90分钟，期间包括两次腹部平片检查。未再观察到出血情况。VSB - P2900可能会简化小肠检查。其顶端控制功能可使插管小肠的大部分得以可视化。工作通道便于进行治疗操作。该技术简单、快速，且大多数内镜医师都具备相关技能。其安全性和有效性还需进一步确定。
