Preventing and controlling bleeding in gastric endoscopic submucosal dissection.

Area of Science:

• Gastroenterology
• Endoscopic Surgery

Background:

• Bleeding remains the most frequent complication following endoscopic submucosal dissection (ESD).
• Effective management of bleeding is crucial as blood can obscure visualization and complicate subsequent endoscopic interventions.
• ESD-related bleeding is categorized into intraprocedural and postprocedural (early and late).

Purpose of the Study:

• To review current strategies for preventing and managing bleeding complications associated with endoscopic submucosal dissection (ESD).
• To highlight the importance of minimizing bleeding for successful ESD outcomes and patient safety.

Main Methods:

• Review of techniques for avoiding intraprocedural bleeding, such as vessel identification and coagulation.
• Discussion of methods to reduce postprocedural bleeding, including pharmacotherapy (e.g., proton-pump inhibitors) and prophylactic coagulation.
• Exploration of adjuncts like medical adhesive spray (n-butyl-2-cyanoacrylate) and countertraction devices.

Main Results:

• Intraprocedural bleeding can be minimized by careful electrocoagulation of visible vessels before cutting.
• Postprocedural bleeding may be reduced by proton-pump inhibitors, prophylactic coagulation, or medical adhesive spray.
• While endoscopic treatments exist for bleeding, hemoclipping is rarely used during ESD due to interference with resection.

Conclusions:

• Despite advancements in ESD techniques and devices, bleeding prevention remains a critical challenge.
• Continued development of reliable ESD techniques and innovative prophylactic strategies is necessary to further reduce bleeding complications.
