Improved Visualization and Access During Splenic Flexure Mobilization with Artisential®

Overview

Use of the Artisential® articulated laparoscopic grasper during splenic flexure mobilization in laparoscopic low anterior resection significantly enhanced surgical screen utilization by 11.8% without adversely affecting perioperative outcomes. Propensity score-matched analysis demonstrated comparable operation times, hospital stays, complication severity, and lymph node harvest between procedures performed with and without Artisential®.

Background

Laparoscopic surgery is a preferred approach in colorectal cancer due to reduced hospital stays and fewer wound complications. Splenic flexure mobilization (SFM) is a technically challenging step in laparoscopic colectomies because of the splenic flexure's angulated anatomy and variable attachments, which limit surgical visualization. Artisential®, an articulated laparoscopic instrument with 360-degree motion and locking features, may improve access and visualization during SFM. This study evaluates the efficacy and safety of Artisential® use during SFM in laparoscopic low anterior resection (LAR).

Data Highlights

Key Findings

• Application of the Artisential® grasper increased surgical screen utilization during SFM by 11.8%, from 86.4% to 98.2%.
• Propensity score matching balanced baseline characteristics between Artisential® and control groups, improving comparability.
• No significant difference in operation time was observed between groups (202.22 vs. 208 minutes; p=0.706).
• Length of postoperative hospital stay was similar between groups (7.67 vs. 8.75 days; p=0.5).
• Complication severity, graded by Clavien–Dindo classification, showed no significant difference (median grade 1 in both groups; p=0.622).
• The number of harvested lymph nodes, an oncologic quality indicator, was comparable (21 vs. 23; p=0.801), indicating no compromise in oncologic outcomes.

Clinical Implications

The use of the Artisential® articulated grasper during splenic flexure mobilization enhances visualization and working space without increasing operative time or complications. Surgeons may consider incorporating this instrument to facilitate technically challenging dissections while maintaining oncologic safety. Additionally, the reduced workload on assistant surgeons may improve operative ergonomics.

Conclusion

Artisential® utilization during laparoscopic low anterior resection improves surgical field visualization during splenic flexure mobilization without compromising perioperative safety or oncologic outcomes. This supports its adoption as a valuable tool in colorectal laparoscopic surgery.
