Combined Laparoscopic-Endoscopic 'Rendez-vous' Procedure for Minimally Invasive Resection of Gastrointestinal Stromal Tumors of the Stomach

摘要

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the digestive tract with an estimated actual incidence higher than 0.4 per cent. Although GISTs are found throughout the digestive tract, from the esophagus to the rectum, the stomach is the most common site of occurrence in more than half of patients. Surgery represents the main approach for nonmetastatic GISTs: an excision with negative margins without lymphadenectomy is recommended. Recently, to avoid the invasivity of a conventional open surgical technique, the laparoscopic wedge resection has been proposed as a less invasive option without compromising curability.
