This article discusses a new technical approach for total mesorectal excision (TME) using an articulating laparoscopic device. TME is a surgical procedure used to treat rectal cancer, and the quality of TME is crucial for successful outcomes. While laparoscopic surgery was thought to improve the quality of TME compared to open surgery, randomized controlled trials have shown worse outcomes in laparoscopic surgery. The article introduces the ArtiSential device, which allows for wrist movement during laparoscopic TME and can prevent damage to the TME plane. The device is particularly useful when dissecting the left side of the rectum. Although there is a learning curve, using the ArtiSential device offers advantages in laparoscopic surgery without the need for additional platforms. The article concludes with information about the authors' contributions, funding, conflicts of interest, data availability, and ethical considerations. [Extracted from the article]

Purpose: Preoperative colonoscopic (POC) localization is recommended for patients scheduled for elective laparoscopic colectomy for early colon cancer. Among the various localization method, POC tattooing localization has been widely used. Several dyes have been used for tattooing, but dye has disadvantages, including foreign body reactions. For this reason, we have used autologous blood tattooing for POC localization. This study aimed to evaluate the safety and efficacy of the autologous blood tattooing method., Methods: This study included patients who required POC localization of the colonic neoplasm among the patients who were scheduled for elective colon resection. The indication for localization was early colon cancer (clinically T1 or T2) or colonic neoplasms that could not be resected endoscopically. POC autologous blood tattooing was performed after saline injection, and 2 hemoclips were applied., Results: A total of 45 patients who underwent autologous blood tattooing and laparoscopic colectomy were included in this study. All POC localization sites were visible in the laparoscopic view. POC localization sites showed almost perfect agreement with intraoperative surgical findings. There were no complications like bowel perforation, peritonitis, hemoperitoneum, and mesenteric hematoma., Conclusion: Autologous blood is a safe and effective agent for localizing materials that can replace previous dyes. However, a large prospective case-control study is required for the routine application of this procedure in early colon cancer or colonic neoplasms.
