Traditionally, adenomatous rectal lesions and unexpected malignant polyps that could not be removed endoscopically are referred to surgery. Local excision is the treatment of choice, and several techniques have been proposed. The choice of the approach requires that the tumour is excised intact, with a low recurrence rate and limited morbidity. Local excision can be a straight forward or conversely a demanding procedure due to the restricted space in which the surgeon must work and the difficulty of achieving a satisfactory exposure.
We describe a modified stapled transanal rectal resection for the excision of flat lesions with a diameter up to 2 cm and located between 5 and 12 cm from the anal verge.
In our experience, it is quick, simple, and easy to teach but it has not previously been reported. It provides full thickness resection with adequate lateral margins. It overcomes some of the limits of the incomplete surgical field exposure and difficult manipulation, since after the confectioning of double half purse-string suture, the suture and sectioning is made by the stapler device.
传统上,无法经内镜切除的腺瘤性直肠病变和意外的恶性息肉需要转外科手术。局部切除是首选的治疗方法,已经提出了几种技术。选择治疗方法的要求是肿瘤完整切除,复发率低,发病率低。由于外科医生必须在有限的空间内工作,并且难以获得满意的暴露,因此局部切除可能是一个简单的过程,也可能是一个具有挑战性的过程。
我们描述了一种改良的经肛门直肠吻合器直肠切除术,用于切除直径达 2cm 的平坦病变,病变位于肛缘 5-12cm 之间。
根据我们的经验,这种方法快速、简单、易于教学,但尚未见报道。它提供了全层切除,并保证了足够的侧缘。它克服了不完全的手术视野暴露和难以操作的一些限制,因为在制作双半荷包缝线后,缝线和切开由吻合器装置完成。
