The use of the laser for translaparoscopic surgery has brought with it a renewed interest in single-puncture operative laparoscopy. Concern about the extent of visual obstruction created intraoperatively by the use of ancillary instruments through the accessory channel prompted this evaluation. Under normal operative conditions, a 5-mm instrument protruding 10 mm or more beyond the distal end of the laparoscope will obstruct 14.6% of the operator's visual field. Still greater curtailment of endoscopic visualization can be expected when large, modified laser probes are used. The double-puncture laparoscopic technique must be considered the method of choice for translaparoscopic conventional or laser surgical procedures.
激光在经腹腔镜手术中的应用重新引发了人们对单孔手术腹腔镜的兴趣。使用辅助器械通过辅助通道进行手术时，术中造成的视觉阻碍程度引发了此次评估。在正常手术条件下，一根5毫米的器械从腹腔镜远端伸出10毫米或更多时，会遮挡14.6%的术者视野。当使用大型改良激光探头时，预计内镜视野的受限会更严重。对于经腹腔镜的传统或激光手术，双孔腹腔镜技术应被视为首选方法。
