Objective: to assess short-term and long-term outcomes of right hemicolectomy with extensive lymph node dissection using the experience of one clinic.Materials and methods. This retrospective study analyzed data from a prospectively collected database containing information on all patients with right-sided colon cancer that underwent laparoscopic right hemicolectomy with D3 lymph node dissection between 2013 and 2018. We estimated intraoperative blood loss, surgery duration (taken from anesthetic records), frequency of postoperative complications, length of in-hospital stay, duration of lymphorrhea, time to gastrointestinal recovery, integrity of the mesocolon, number and location of removed lymph nodes.Results. A total of 50 underwent laparoscopic right hemicolectomy with D3 lymph node dissection. No cases of surgical conversion were registered. Median surgery duration was 185 min; median blood loss was 30 mL. No postoperative mortality was observed in the study cohort. Twelve (24 %) patients had postoperative complications; 2 (4 %) patients underwent repeated surgery. Median number of lymph nodes examined was 26; high-quality specimens (G ) were obtained in 48 (96 %) patients. At a median follow-up of 19.5 months, 2 (4 %) patients had disease progression (developed liver metastases).Conclusion. Our results confirm safety of laparoscopic approach for right colon resection with D3 lymph node dissection
