Hand-eye discordance during laparoscopic colon surgery is an obstacle to the assistant. We evaluated the usefulness of a 180° rotatable laparoscopic monitor for the colorectal surgery assistant to overcome hand-eye discordance.
Twenty-six residents of the department of surgery (novice group, n=13; experienced group, n=13) participated in this study. They performed grasping a ring and transferring it to standing bars on a laparoscopic training kit under the conventional view and a 180° rotated monitor view. We defined successful performance when this procedure was completed in 3 minutes.
The number of successful performance was higher under the 180° rotated monitor view than under the conventional view monitor (6.88±2.79 vs. 0.92±0.80, <0.01). Under the 180° rotated monitor view, the experienced group had a higher number of successful performances than the novice group (8.31±2.59 vs. 5.46±2.26, =0.009). However, no statistically significant difference was found between the two groups under the conventional view (1.23±0.93 vs. 0.62±0.51, =0.091).
This study shows the usefulness of a 180° rotated monitor view to overcome hand-eye discordance, which adversely affects the laparoscopic performance of the colorectal surgery assistant.
腹腔镜结肠手术中的手眼不协调是助手面临的一个障碍。我们评估了180°可旋转腹腔镜监视器对结直肠手术助手克服手眼不协调的有效性。
26名外科住院医师（新手组，n = 13；经验丰富组，n = 13）参与了本研究。他们在传统视野和180°旋转监视器视野下，在腹腔镜训练套件上抓取一个环并将其转移到立杆上。当此操作在3分钟内完成时，我们定义为操作成功。
180°旋转监视器视野下的成功操作次数高于传统视野监视器下的成功操作次数（6.88±2.79对0.92±0.80，<0.01）。在180°旋转监视器视野下，经验丰富组的成功操作次数高于新手组（8.31±2.59对5.46±2.26，=0.009）。然而，在传统视野下，两组之间未发现统计学上的显著差异（1.23±0.93对0.62±0.51，=0.091）。
本研究表明180°旋转监视器视野有助于克服手眼不协调，手眼不协调会对结直肠手术助手的腹腔镜操作产生不利影响。
