Summary
Brief summary (as posted)
The purpose of this research protocol is to compare open versus laparoscopic right colectomy (according to the CME technique of complete mesocolic excision) for right colon cancer. This study will be designed as a prospective randomized controlled trial. The comparison of the two techniques will include endpoints regarding the quality characteristics of the specimens and the oncological results. In addition, the effectiveness of the two methods will be evaluated in terms of the early and late postoperative period.

- label
- Laparoscopic right colectomy
- description
- In laparoscopic right colectomy subgroup, the patient will be placed in a lithotomy position. Entrance in the peritoneal cavity will be completed via the open Hasson method. Overall, 4 ports will be used: 10mm at the umbilicus for optical entry, 12mm in the left midclavicular line below the umbilicus as the main working port, 5mm at the McBurney point, and 5mm between the umbilicus and the xiphoid process. Dissection of the peritoneal fold, under the terminal ileum, will be performed based on the medial to lateral approach. Similar to the open approach, the ileocolic vessels, as well as the right branches of the middle colic will be ligated at their origin for cecal and proximal ascending tumors. For hepatic flexure cancers, the medial colic vessels will be ligated. The ileocolic anastomosis will be completed either intracorporeally or extracorporeally, using staples or sutures.

- ACTIVE_COMPARATOR
- label
- Open right colectomy
- description
- In the open right colectomy group, the operation will start with a midline incision and dissection based on the lateral to medial approach. The lateral peritoneal fold along Toldt's line will be incised and the ascending colon will be mobilized from the retroperitoneum according to the embryological dissection planes. Dissection will continue until the anterior surface of the superior mesenteric vessels at the third duodenal part. Ileocolic and right colic vessels will be ligated at their origins. For hepatic flexure tumors, the middle colic vessels will be also ligated at their origin. The ileocolic anastomosis will be performed using an automatic stapler. The anastomosis will be completed either with staples or sutures.
