Rubber-band ligation is superior to sclerotherapy, and is considered to be the endoscopic treatment of choice for bleeding varices. The single-shot mechanism of the ligation device generally used is inherently inefficient, and makes the procedure tedious. It also requires overtube placement, associated with discomfort and complications. This study describes the Saeed Six-Shooter, a multiple ligation device.
Twenty-seven consecutive patients with variceal bleeding were prospectively studied. After initial endoscopic ligation, subsequent sessions were every 7-10 days. The parameters studied were the ease of use, the ability to control active bleeding and eradicate varices, survival, and complications.
Active bleeding was controlled in all seven (100%) patients. Esophageal varices were eradicated in 70% (3.2 +/- 1.2 sessions), and gastric varices in 88% of patients (2 +/- 1.2 sessions). Five patients re-bled, two from esophageal varices, two from gastric varices, and one from treatment-induced ulcer. There were four deaths, none due to exsanguination. A single complication, esophageal stricture, resolved with balloon dilation. Intubation was no more difficult with the endoscope loaded with the Six-Shooter than with the endoscope alone (P > 0.3). Six ligations were performed in 39% of cases within 60 seconds, and in 74% of cases within 90 seconds. For gastric varices, the device was effectively used with the endoscope retroflexed.
The Saeed Six-Shooter is a safe and efficient instrument for the endoscopic ligation of varices, and has overcome the limitations of the single-shot ligator.
橡皮圈套扎术优于硬化疗法,被认为是治疗静脉曲张出血的内镜治疗首选方法。一般使用的套扎装置的单次操作机制本质上效率低下,使得操作繁琐。它还需要放置外套管,会带来不适和并发症。本研究描述了一种多次套扎装置——赛义德六连发套扎器。
对27例连续的静脉曲张出血患者进行前瞻性研究。首次内镜套扎后,后续疗程每7 - 10天进行一次。研究的参数包括易用性、控制活动性出血和消除静脉曲张的能力、生存率及并发症。
所有7例(100%)患者的活动性出血均得到控制。70%的患者(3.2±1.2个疗程)食管静脉曲张被消除,88%的患者(2±1.2个疗程)胃静脉曲张被消除。5例患者再次出血,2例来自食管静脉曲张,2例来自胃静脉曲张,1例来自治疗引起的溃疡。有4例死亡,均非因失血过多。发生了1例并发症,即食管狭窄,经球囊扩张后缓解。装有六连发套扎器的内镜插管并不比单纯内镜更困难(P>0.3)。39%的病例在60秒内完成6次套扎,74%的病例在90秒内完成。对于胃静脉曲张,该装置在内镜反转时能有效使用。
赛义德六连发套扎器是一种用于内镜下静脉曲张套扎的安全有效的器械,克服了单次套扎器的局限性。
