Adoption of standardized approach to right hemicolectomy with complete mesocolic excision using the critical view concept and open-book model for robotic surgery - a video vignette

[Extended Complete Mesocolic Excision in right-sided Colon Cancer - An Overview]

Surgical resection with systematic lymphadenectomy remains the standard of care for non-metastasised colon cancer. After the article of Hohenberger et al. in 2009 describing the surgical technique of complete mesocolic excision (CME), D2 lymphadenectomy has been called into doubt after the finding of a better oncological outcome. However, there has been also a controversial discussion about the oncological value of CME, since intraoperative complications may increase. Additional evidence has been provided in recent years from randomised controlled multicentre studies showing that the reported improved oncological long-term outcome after CME is more than questionable. The reported increased rate of intraoperative (vascular) complications could be not confirmed.

Laparoscopic right hemicolectomy with complete mesocolic excision and D3 lymphadenectomy using the open book approach: a video vignette

According to the concept of total mesorectal excision for rectal cancer, Hohenberger translated this concept to colonic cancer by introducing complete mesocolic excision (CME). The concept of this surgical technique was further elucidated by Benz et al. in the form of an open book approach. This article presents and demonstrates in a video a case of laparoscopic right hemicolectomy with CME and D3 lymphadenectomy using open book approach in the treatment of a T3N1M0 distal ascending colonic adenocarcinoma. The final pathology report confirmed moderately differentiated adenocarcinoma with a maximum tumor size of 55 mm and 0/60 lymph nodes. The mesocolic fascia was intact and R0 was achieved. The final staging was pT3pN0pM0. However, D3 lymphadenectomy is not universally adopted due to concerns of higher morbidity we believe that with adequate training and supervision CME with D3 LDN is feasible and safe to be offered to all right-sided colorectal cancers with curative intent treatment.

Novel mobilization of the medial approach without changing the position for robotic right hemicolectomy

Conventional laparoscopic or robotic surgery for right-sided colon cancer often requires intraoperative repositioning and removal of the bowel. Changing positions during robotic surgery can be troublesome and robotic removal of the small intestine carries a risk of unexpected injury because robotic devices have a strong grasping force and no sense of touch. Herein, we introduce a novel mobilization of the medial approach without changing the position for robotic right hemicolectomy. Using this technique, mobilization is performed in counterclockwise succession, allowing all mobilizations and bowel removal to be completed sequentially, without positional change.
