About this trial
A single-center prospective study to elucidate whether extended robot-assisted right colectomy (e-RARC) performs as well as extended open right colectomy (e-ORC) in terms of specimen quality, and in addition, whether less postoperative morbidity and shorter length of stay (LOS) can be attained. Patients with colonic cancer near the right flexure or the oral part of the transverse colon will be compared excluding the most technically demanding and frail patients in both groups. A total of 40 patients undergoing e-RARC in a prospective series will be included and compared with 44 consecutive patients previously treated with e-ORC.

Treatments tested in this trial
Robot-assisted laparoscopic extended right colectomy
DeviceAn extended right hemicolectomy with total mesocolic excision and meticulous central dissection as described by Hohenberger will be performed with the DaVinci Xi robot by one of two dedicated surgeons
