Endoscopic submucosal dissection (ESD) is a minimally invasive surgical technique used to remove early-stage tumors from the digestive tract. While ESD has many benefits compared to traditional surgery, it can be a challenging and time-consuming procedure that requires specialized tools and expertise. A new device called Speedboat-rs2 has been developed to address these challenges and improve the efficiency of ESD for gastric and oesophageal submucosal dissection.

The Speedboat-rs2 is a multi-modality endoscopic device that combines various functions, including dissection, coagulation, and suction. The device consists of a flexible endoscope with a built-in dissection knife that can be controlled by a foot pedal. The device also includes an integrated water jet and suction system that allows for efficient and precise dissection of the submucosal layer.

One of the key benefits of the Speedboat-rs2 is that it can improve the efficiency of ESD. The device allows for simultaneous dissection, coagulation, and suction, which can reduce the time required for the procedure and improve patient outcomes. Additionally, the device's built-in water jet and suction system can help maintain a clear field of vision, which can help surgeons visualize the area they are working on and reduce the risk of complications.

Another benefit of the Speedboat-rs2 is that it can reduce the learning curve for surgeons who are new to ESD. The device is designed to be easy to use and requires minimal training, which can help new surgeons quickly develop the skills they need to perform ESD with precision and efficiency. Additionally, the device's integrated water jet and suction system can help reduce the likelihood of errors and complications, which can help build the confidence of new surgeons and improve patient outcomes.

The Speedboat-rs2 has been used successfully in a variety of ESD procedures, including those for early-stage gastric and oesophageal tumors. Studies have shown that the device is effective in improving the efficiency of ESD and reducing the time required for the procedure. For example, a study published in the Journal of Gastroenterology and Hepatology found that the Speedboat-rs2 was effective in reducing the procedure time for gastric ESD by 43%.

In addition to improving the efficiency of ESD, the Speedboat-rs2 also has the potential to reduce the risk of complications associated with the procedure. Complications from ESD can be significant and include bleeding, perforation, and infection. The device's integrated water jet and suction system can help reduce the risk of bleeding by allowing surgeons to maintain a clear field of vision and identify blood vessels more easily. Additionally, the device's built-in coagulation function can help reduce the risk of bleeding and perforation by enabling surgeons to control bleeding and seal the tissue as they dissect it.

While the Speedboat-rs2 has many benefits, there are also some potential drawbacks to consider. One of the main drawbacks is the cost of the device. The Speedboat-rs2 is more expensive than traditional ESD tools, which may be a barrier to adoption for some surgical facilities. Additionally, the device requires specialized training and expertise to use effectively, which may limit its use in some settings.

Another potential drawback of the Speedboat-rs2 is that it may not be suitable for all ESD procedures. While the device has been used successfully in a variety of procedures, it may not be appropriate for procedures that involve delicate or highly vascular tissue. Surgeons must carefully evaluate each case to determine whether the Speedboat-rs2 is the most appropriate tool for the job.

Despite these potential drawbacks, the Speedboat-rs2 represents an important advance in ESD tools and techniques. The device has the potential to improve the efficiency of ESD and reduce the risk of complications, which can benefit both patients and surgeons. As the technology continues to evolve, it is likely that we will see further improvements in ESD tools and techniques, which will continue to advance the field and improve patient outcomes.

In addition to the Speedboat-rs2, there are several other tools and techniques that are used in ESD procedures. One of these is the hybrid knife, which combines a cutting knife and a high-frequency electric current to enable more precise dissection. The hybrid knife has been used successfully in a variety of ESD procedures, including those for early-stage gastric cancer and rectal tumors.

Another tool used in ESD procedures is the dual knife, which is designed to enable more efficient and precise dissection. The dual knife consists of two blades that work together to cut tissue and coagulate blood vessels simultaneously. The device has been used successfully in a variety of ESD procedures, including those for early-stage colorectal tumors.

While the Speedboat-rs2, hybrid knife, and dual knife all offer advantages in ESD procedures, it is important to note that each technique has its own unique set of benefits and drawbacks. Surgeons must carefully evaluate each case to determine which technique is the most appropriate for the procedure and the patient.

It is worth noting that the development of new tools and techniques in ESD is driven by the need to improve patient outcomes and reduce the risks associated with traditional surgical procedures. Traditional surgery can be highly invasive and can require long recovery times, which can be challenging for patients. ESD, on the other hand, is a minimally invasive procedure that can be performed on an outpatient basis in some cases, which can reduce the burden on patients and improve their quality of life.
