Methods: Patients with a histological diagnosis of HCA were included in this analysis.

Robotic right colectomy for hemorrhagic right colon cancer: a case report and review of the literature of minimally invasive urgent colectomy.

Right colon cancer rarely presents as an emergency, in which bowel occlusion and massive bleeding are the most common clinical presentations. Although there are no definite guidelines, the first line treatment for massive right colon cancer bleeding should ideally stop the bleeding using endoscopy or interventional radiology, subsequently allowing proper tumor staging and planning of a definite treatment strategy. Minimally invasive approaches for right and left colectomy have progressively increased and are widely performed in elective settings, with laparoscopy chosen in the majority of cases.

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.
