A Randomized Comparison of UnderwateR Versus Regular Coagulation in Endoscopic Submucosal DissectioN and Third Space Endoscopy

Istituto Clinico Humanitas·interventional·Posted Apr 7, 2023·Updated Apr 3, 2025

In Brief

A clinical study evaluating Coventional coagulation and Underwater coagulation for Gastrointestinal Diseases and Endoscopic Surgery. Completed, enrolled 73 participants across 1 site.

Detailed Summary

What the investigatorpropose in this protocol is a technique already used in clinical practice. It prevents the risk of bleeding and make third space endoscopy easier, quicker, safer and cheaper. Indeed, we noticed that preventive underwater coagulation of the candidate vessels during the submucosal dissection with the Hybrid Knife (HK), seal the wall of the vessel, resulting in a subsequent cut under CO2 without any bleeding. Such preventive coagulation is likely to be related with the conduction of the current underwater as it focalizes all the power on the interface between the vessel and the water, allowing a soft sealing of the vessel without cutting it. Despite widely used, there is no evidence up to know on the benefit and harm of such coagulation technique. The hypothesis is that the use of this approach in clinical practice, especially when used to coagulate a vessel, may lead to an increase in safety, feasibility and cost-effectiveness, reducing the procedural time, the rate of complications and the need for coagulation forceps in comparison with the conventional preventive coagulation technique under CO2 insufflation. Therefore, this randomized study compares the underwater coagulation technique with the conventional coagulation technique in the CO2 setting during the submucosal dissection in third space endoscopy.

Interventions

Coventional coagulationprocedure

In the conventional group, the haemostasis of vessels will be performed with the conventional coagulation technique under CO2 insufflation. First, submucosal fibres surrounding a blood vessel will be dissected and the vessel will be isolated. After, both sides of the isolated vessel will be coagulated using SWIFT COAG E3, 89 W for POEM and SWIFT COAG E4, 124 W for ESD until the blood vessel turns white and can be finally cut.

Underwater coagulationprocedure

In the treatment group, the prophylactic haemostasis of vessels will be accomplished by the underwater coagulation technique. First, physiological solution will be instilled until there is no more air around the blood vessel. Then, the vessel will be coagulated using SWIFT COAG E3, 89 W for POEM and SWIFT COAG E4, 124 W for ESD until it turns white and, after the removal of all the physiological solution, can be finally cut.
