Laparoscopy-assisted nonexposed endoscopic full-thickness resection for local resection after endoscopic submucosal...

Area of Science:

• Gastroenterology
• Surgical Oncology
• Endoscopic Surgery

Background:

• Endoscopic submucosal dissection (ESD) is a standard treatment for early gastrointestinal cancers.
• Microscopic residual tumor after ESD can necessitate further treatment.
• Minimally invasive surgical options are sought for residual tumor resection.

Purpose of the Study:

• To present a video demonstrating nonexposed endoscopic wall inversion surgery.
• To illustrate the technique for local resection of microscopic residual tumor after ESD.
• To highlight the feasibility of this approach for complete tumor removal.

Main Methods:

• The video showcases a step-by-step procedure of nonexposed endoscopic wall inversion surgery.
• The technique involves inverting the endoscope to access the submucosal layer.
• Surgical resection of the residual tumor is performed using endoscopic instruments.

Main Results:

• The procedure successfully achieved local resection of the microscopic residual tumor.
• The nonexposed endoscopic approach allowed for precise tumor removal.
• The technique appears to be a viable option for managing post-ESD residual disease.

Conclusions:

• Nonexposed endoscopic wall inversion surgery is an effective minimally invasive technique.
• This method facilitates complete resection of microscopic residual tumors after ESD.
• Further studies are warranted to evaluate long-term outcomes and broader applicability.
