Interventional
Description of intervention(s) / exposure
Surgeon will perform Right hemicolectomy performed by a robotic surgery using the da Vinci Xi surgical robotic
A robotic right hemicolectomy is performed with the da VINCI Xi surgical robot using up to four robotic arms to control small instruments introduced into the abdomen through 3 – 6 small incisions on the abdomen measuring around 8mm. One robotic arm is used for a camera. The tumour is removed through another incision (about 5cm to 8cm). The approximate duration of surgery is two hours. Surgeons will be required to electronically record every operation they perform in this study.
Intervention code [1] 318412 0
Treatment: Surgery
Comparator / control treatment
Right hemicolectomy performed by laparoscopic surgery
A laparoscopic right hemicolectomy is performed using small instruments on long handles introduced into the abdomen through small ports called trocars in 3 to 6 positions on the abdomen through 3 – 6 small incisions measuring 5 to 10 mm, under the guidance of a video camera. The tumour is removed through another incision (about 5cm to 8cm). The approximate duration of surgery is two hours. Surgeons will be required to electronically record every operation they perform in this study.

Outcomes
Primary outcome [1] 324880 0
To determine if performing right hemicolectomy robotically compared with laparoscopic hemicolectomy in patients with adenocarcinoma of the caecum, ascending or proximal transverse colon improves surgical morbidity.
Surgical morbidity/mortality up to 90 days (as measured by Clavien-Dindo and the Comprehensive Complication Index).
.
Timepoint [1] 324880 0
90 days post-surgery.
Secondary outcome [1] 386087 0
Pathological quality assessment.The completeness of mesocolon excision (CME) according to Benz classification:
o Anatomical completeness of the mesocolon (Type 0–III)
o Three subcategories (A,B,C) for integrity of the mesocolon
o Distal resected margin equal to or greater than 5cm
o Lymph node yield
o Mesocolic plane of surgery
o R0 resection (all margins clear)

Immediate post-operative period
Secondary outcome [2] 386213 0
Successful surgical episode of care which be deemed to have been achieved only if all eight (8) of the following binary outcomes are obtained.
a. No ileus or insertion of nasogastric tube (NGT) (defined as ‘tolerating diet’ by Day 2).
b. No anastomotic complication (leak, haemorrhage, stenosis requiring reoperation, endoscopic intervention or transfusion).
c. No surgical site infection (at specimen extraction site).
d. No prolonged hospital stay or unplanned readmission (>1.5 SD above the mean, adjusted for each geographical region) (after day of surgery).
e. No wound hernia at 12 months (patient reported or clinical examination, ultrasound or CT).
f. No conversion or change in operative approach to otherwise achieve the final goal (defined as inability to complete the dissection, including the vascular ligation and/or requiring an incision larger than that required to remove the specimen, or perform extracorporeal anastomosis) i.e. laparoscopic-assisted technique to a robotic or hand-assisted or hybrid procedure, robotic-assisted technique to a laparoscopic or hand-assisted or hybrid procedure, or any conversion to an open procedure. If a planned intracorporeal anastomosis is not completely performed in an intracorporeal approach, the case is considered also to have been converted.
g. No other significant post-operative complication, including DVT/PE, acute renal failure, cardiac or respiratory complications (Clavien-Dindo grades III or higher).
h. Pathologically clear resection margins (R0).

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation by computer
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Using the method of minimization and stratifying for gender, BMI (<30 v >30) tumour site (caecum/ascending colon v. hepatic flexure or proximal transverse colon) and surgeon, appropriate weights will be implemented in the minimisation algorithm in order to preserve the proposed 2:1 ratio favouring the experimental arm.

Statistical methods / analysis
RoLaCaRT-1 has been designed as a 50 patient pilot study for the assessment of 90-day surgical morbidity/mortality, patient reported outcomes and study feasibility.
Analyses will be conducted according to the principle of intention to treat (ITT). Exploratory comparisons will comprise of tests for continuous and some categorical outcomes (e.g., positive margins). Descriptive statistics will be reported counts with percentages for categorical variables.
