Endoscopic Submucosal Dissection for Early Gastric Cancer Using a Novel Bending Attachment
Endoscopic submucosal dissection (ESD) is a minimally invasive technique used for the removal of early-stage gastrointestinal cancers, including early gastric cancer. This procedure allows for precise en bloc resection of lesions while preserving healthy tissue. However, ESD can be technically challenging, particularly in areas where access and visualization are limited, such as the lesser curvature of the upper gastric body.
In this context, a novel single-use bending attachment, called the AttachBend, has been successfully utilized to enhance the ESD procedure for a patient with early gastric cancer. The AttachBend is a lightweight accessory designed to provide an additional bending function to a standard thin therapeutic endoscope, addressing the limitations of conventional multibending endoscopes. Traditional multibending endoscopes, while effective, can be expensive, heavier, and may increase operator burden, making them less practical for routine use.
Case Description
The patient presented with early gastric cancer located in the lesser curvature of the upper gastric body. During the ESD procedure, the operator faced technical difficulties due to the orientation of the muscle layer, which was directly facing the endoscope. This positioning made it challenging to maintain a clear view of the submucosal layer and perform safe dissection.
To overcome these challenges, the AttachBend was mounted onto the endoscope. This attachment allowed the operator to manually adjust the bending angle of the endoscope, enabling a parallel approach to the muscle layer. This adjustment significantly improved visualization of the submucosal space and facilitated effective countertraction using the endoscopic hood.
Advantages of the AttachBend
Enhanced Visualization: The added bending capability provided a better view of the submucosal layer, which is critical for safe and precise dissection.
Improved Maneuverability: The attachment allowed for more precise positioning of the dissection knife, enabling controlled and smooth dissection of the lesion.
Safety: The improved access and visualization reduced the risk of complications, such as perforation or incomplete resection.
Cost-Effectiveness: Unlike multibending endoscopes, the AttachBend is a single-use accessory, offering a more affordable and lightweight alternative without requiring specialized equipment.
Outcome
The use of the AttachBend resulted in successful en bloc resection of the lesion without any adverse events. Pathological examination confirmed complete removal of the cancerous tissue with negative margins, indicating no residual disease. This outcome highlights the practical advantages of the AttachBend in overcoming technical difficulties during gastric ESD.
Conclusion
The AttachBend represents a promising innovation for enhancing the safety, efficiency, and accessibility of gastric ESD in routine clinical practice. By improving access, visualization, and maneuverability, this novel attachment addresses common challenges associated with conventional techniques, offering a cost-effective and operator-friendly solution. Its successful application in this case suggests that it may be a valuable tool for managing early gastric cancer and potentially other gastrointestinal lesions requiring ESD.
