Clinical and Morphological Characteristics of Gastrointestinal Stromal Tumor.

Gastrointestinal stromal tumors (GIST) are a rare form of cancer located within the gastrointestinal (GI) tract, defined as tumors with spindle, epithelioid, or occasionally pleomorphic cells. They originate in the interstitial cells of Cajal, with the function of "pacemaker" of gastrointestinal motility. Their behavior is dictated by changes in the c-kit/PDGFRA gene, which is often highlighted by immunolabeling.

Mini-laparoscopic cholecystectomy with the MiniLap percutaneous surgical system: a series of 32 patients.

Background: In recent years, mini-laparoscopic procedures are gaining the preference of most surgeons due to their potentially better surgical outcomes. The Mini Lap Percutaneous Surgical System with MiniGrip Handle is currently the less invasive instrument and can be applied to a wide range of operations. The current paper presents its application on percutaneous laparoscopic cholecystectomy.
