Echocolonoscopy--an indispensable procedure before and after transanal endoscopic microsurgery

Area of Science:

• Gastroenterology and Surgical Oncology

Background:

• Intraluminal sonography is a common practice for rectal tumor assessment.
• Accurate preoperative staging and postoperative follow-up are crucial for effective rectal cancer management.

Purpose of the Study:

• To introduce echocolonoscopy as an advancement over traditional intraluminal sonography.
• To highlight the benefits of combined colonoscopy and intraluminal sonography in a single session.
• To emphasize its role in improving diagnostic accuracy for rectal tumors.

Main Methods:

• Echocolonoscopy integrates standard colonoscopy with intraluminal sonography.
• Utilizes the Olympus echocolonoscope for simultaneous optical and ultrasound visualization.
• Employs optical control to mitigate diagnostic errors from tangential views or fecal residue.

Main Results:

• Echocolonoscopy offers a refined approach to rectal tumor staging and patient follow-up.
• Simultaneous visualization prevents misinterpretations common in separate procedures.
• Improved accuracy in endosonographic diagnosis is achieved.

Conclusions:

• Echocolonoscopy represents a significant breakthrough in the management of rectal tumors.
• It enhances diagnostic precision, reducing errors associated with conventional methods.
• The technique is particularly valuable in the context of transanal endoscopic microsurgery for pre- and post-operative assessment.
