Background/aim: The effectiveness of a transanal drainage tube (TAT) for the prevention of anastomotic leakage after double stapling technique (DST) anastomosis in colorectal cancer has been reported. Previously, TATs had been placed and connected to drainage bags. It was considered that a higher decompression effect could be expected by inserting an open-type TAT, without connection to a drainage bag.

New alternative colorectal anastomotic devices: A systematic review and meta-analysis.

Am J Surg

February 2025

Ellen Leifer Shulman and Steven Shulman Digestive Disease Center, Cleveland Clinic Florida, Weston, FL, USA.

Article Synopsis
  • Colorectal anastomotic devices have been used for almost 100 years, with stapled methods being most common, despite a significant leak risk of up to 20%.
  • A systematic review and meta-analysis explored newer anastomotic devices, analyzing 18 studies from the last decade, which included 955 anastomoses and focused on non-stapled methods.
  • The findings indicated a pooled complication rate of 9.7% for human studies, but new compression mechanisms showed a much lower leak rate of 3.3%, suggesting that these novel technologies could improve surgical outcomes.

Background/aim: In rectal cancer surgery, anastomotic leakage (AL) is the most important complication and has a reported frequency of 11-15%. The causes of AL leakage are complex, and AL prevention should be performed in multiple directions. Thus, this study examined the usefulness of the comprehensive and multifaceted AL preventive measures.

Enhanced transanal surgery training through a 4K 3D surgical exoscope: a novel approach for transanal surgery.

Int J Colorectal Dis

October 2024

Department of Biomedical Sciences, Humanitas University, Via Rita Levi Montalcini 4, 20072, Pieve Emanuele, Milan, Italy.

Article Synopsis
  • The exoscope, a more ergonomic alternative to traditional microscopes, is being explored in general surgery, specifically for transanal procedures like ileal-pouch anal anastomosis.
  • Surgeons performed a transanal procedure using the ORBEYE™ exoscope system, which provided a high-resolution, 3D view on a large screen, enhancing their ability to operate while keeping a comfortable position.
  • The results indicate that the exoscope offered excellent visualization and could improve surgical training by allowing trainees to see techniques clearly, suggesting its potential as a valuable tool in colorectal surgery.
