[Progress in the application of laparoscopic and endoscopic cooperative surgery in gastrointestinal stromal tumors].

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor among gastrointestinal tumors, with an inherent potential for malignancy. The primary approach to addressing GIST remains surgical intervention. Laparoscopic and endoscopic cooperative surgery (LECS) has emerged as an innovative treatment approach for GIST. LECS includes various techniques, such as classic LECS, inverted LECS, and laparoscopic-assisted endoscopic full-thickness resection, all of which aim to combine the advantages of laparoscopy and endoscopy. This treatment offers benefits such as accurate localization, complete lesion removal, and a good prognosis. Generally, LECS can be used for GIST with a tumor diameter less than 50 mm, which cannot be completely removed through traditional endoscopic surgery. The clinical application of LECS deserves further exploration and expansion in the future, ultimately benefiting patients.
