[Laparoscopic Right Hemicolectomy with Complete Mesocolic Excision (CME)].

INTRODUCTION

Complete mesocolic excision (CME) is considered as good clinical practice according to the German S3 Guideline for colorectal cancer. This recommendation is based on evidence showing improved histopathological quality criteria of specimens taken and better oncological outcomes following CME surgery compared to conventional colon resections. However, CME surgery, especially of the right colon, is more complex - due to the high variability of the vascular structures (e.g. Truncus Henle) and the anatomical proximity to the stomach, duodenum and pancreas. To increase safety of laparoscopic right hemicolectomy with CME and to improve surgical education of this procedure, a German expert group has developed a standardised procedure with critical safety assessment. This video shows the technique of laparoscopic right hemicolectomy with complete mesocolic excision (CME), according to the concept first described by the German expert group on Lap-CME.

INDICATION: Carcinoma of the ascending colon.

PROCEDURE: Laparoscopic right hemicolectomy with complete mesocolic excision (CME).

CONCLUSION

The proposed standardisation of laparoscopic right hemicolectomy with complete mesocolic excision accommodates the increased complexity of the right colon and structures it into well-defined steps with critical safety assessments, which may result in minimised intraoperative complications and increased patient safety and should improve training.
