THE PURPOSE OF THE ARTICLE WAS TO COMPARE THE EFFICACY AND SAFETY OF ROBOTIC TOTAL GASTRECTOMY (RTG) AND LAPAROSCOPIC TOTAL GASTRECTOMY (LTG) FOR THE TREATMENT OF CARCINOMA IN THE REMNANT STOMACH (CRS). A RETROSPECTIVE ANALYSIS OF DATA FROM PATIENTS WHO UNDERWENT RTG OR LTG FOR CRS AT A SPECIFIED HOSPITAL BETWEEN MAY 2006 AND OCTOBER 2019 WAS CONDUCTED. ALL SURGERIES WERE PERFORMED BY ONE SURGEON. THE SURGEON PERFORMED A TOTAL OF 27 ROBOTIC GASTRECTOMIES (RG). THE SURGICAL METHOD OF ROBOTIC VERSUS LAPAROSCOPIC WAS SELECTED BY EACH PATIENT. THE DA VINCI SURGICAL SYSTEM WAS USED FOR 29 PATIENTS. FIVE CASES IN THE RTG GROUP UNDERWENT CONVERSION TO OPEN SURGERY. THE REASONS FOR CONVERSION TO OPEN SURGERY IN THE ROBOTIC GROUP INCLUDED 3 CASES OF EXTENSIVE ADHESIONS, 1 CASE OF TUMOR INVASION TO THE TRANSVERSE COLON, AND 1 CASE OF TUMOR INVASION TO THE DIAPHRAGM.
