Laparoscopic versus open gastric wedge resection for primary gastrointestinal tumors: clinical outcomes and health care costs analysis.

The study aimed to compare laparoscopic wedge resection (LWR) versus open-wedge resections (OWR) for primary gastrointestinal stromal tumors (GISTs) of the stomach. Twenty-five patients who underwent LWR were matched by tumor size and location with 25 patients who underwent OWR. GISTs close to the pylorus or the esophagogastric junction, incidental, and metastatic GISTs were excluded.

Laparoscopic surgery for double gastrointestinal stromal tumor of the stomach: a report of two cases.

Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors that originate from interstitial cells of Cajal or their stem cell-like precursors. Generally, GISTs have specific c-KIT gene mutations. The incidence of GISTs is estimated to be 10 to 20 cases/one million individuals, and GISTs typically affect people over 50 years of age.
