Secondary study designCluster randomised trial
Study setting(s)Hospital
Study typeTreatment
Scientific titleCOmplete Mesocolic Excision vs. standard of care right hemicolectomy randomised controlled Trial
Study acronymCOMET
Study objectivesComplete mesocolic excision and central vascular ligation results in a larger specimen with more lymph nodes than standard of care right hemicolectomy surgery.
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedRight sided colonic adenocarcinoma
InterventionIntervention - CME/CVL right hemicolectomy
Control - standard of care right hemicolectomy
Intervention typeProcedure/Surgery
Primary outcome measure1. Size of resection specimen
2. Number of lymph nodes present
Secondary outcome measures1. Operative time (minutes, intraoperative)
2. Blood loss (ml, intraoperative - swab weight and suction volume)
3. Length of hospital stay (postoperative days)
4. Early morbidity (30 day postoperative complications, Clavien-Dindo Classification, prospective observational recording from case notes and clinical team)
5. Surgical technique (open, laparoscopic or robotic, size of specimen, number of lymph nodes and above secondary outcomes)
6. Three year disease free and overall survival (observational recording from MDT records)
7. Specimens not compatible with CME/CVL surgery (Histopathological and/or operative video assessment - interventional arm only)
8. Extent of standard of care right hemicolectomy surgery (specimen size and number of lymph nodes, post-operative histopathological assessment)
