Welcome to The Advanced Colorectal Surgery Unit (ACS)
Based at The Wellington Hospital, The Advanced Colorectal Surgery Unit (ACS) offers a wide range of treatments for bowel disease. We offer both complex and conventional colorectal surgery including keyhole surgery for Crohn’s disease and diverticular disease. Our surgeons use the latest in diagnostic and treatment options, including transanal endoscopic microsurgery (TEM), transanal minimally invasive surgery (TAMIS), transanal Total Mesorectal Excision (taTME), robotic surgery and intraoperative radiotherapy.
Offering a pioneering ‘two-surgeon approach’, we're one of only two private centres in the UK specialising in locally advanced colon and rectal cancer, as well as cytoreduction and heated intrapertoneal chemotherapy (HIPEC) for colorectal peritoneal metastases.

Our technology

The da Vinci© Surgical System
The da Vinci© robot can be used to carry out colorectal surgery because the system allows our surgeons to perform incredibly delicate procedures through the smallest of incisions.

Laparoscopy (gastrointestional)
We believe laparoscopic (keyhole) surgery offers the best patient experience, including quicker recovery time, reduced complications and less pain.
The patient benefits of laparoscopic and robotic surgery:
-
A reduced hospital stay
-
Eating solids sooner
-
Less pain following surgery
-
Less pain relief needed
-
A smaller incision required
-
Ability to be mobile, sooner
