Development of Minimally Invasive Surgery

St Mark's Hospital has been pioneering new surgical treatments for 180 years. The innovations developed aim to improve recovery for patients and reduce complications.

St Mark’s Hospital has pioneered new surgical technique since 1835 and the development of minimally invasive surgery has continued as a defining feature of the institution.

The development of minimally invasive surgery aims to improve accuracy during operations to ensure that

  • Less healthy tissue is removed
  • Recovery time is improved
  • There is reduced risk of complications post-surgery

Pioneered by Sir Alan Parks at St Mark’s in the 1970s, the ileo-anal pouch operation is a surgical treatment for aggressive ulcerative colitis. The formation of an ileo-anal pouch provides an option for patients with this condition to live without a stoma. In effect, the ileo-anal pouch has proved to be completely life changing. The operation has been performed in more than 25,000 patients worldwide!

The latest developments are; full thickness laparoendoscopic excision, FLEX and Transanal submucosal resection, TASER. The newest development is the Surgical Robotics Research Programme.

FLEX

Developed by Professor Robin Kennedy, FLEX can safely and efficiently perform full-thickness bowel wall removal of a polyp. It aims to avoid shortening of the bowel, pain, inter-abdominal scarring, the need for re-admission and the avoidance of unbearable toilet frequency.

This technique was first introduced into clinical practice in 2014 and it is to be explored further over the next ten years, offered to patients with early stages of cancer. This should help these patients avoid undergoing major surgery.

TASER

Developed by Professor Brian Saunders and Mr Janindra Warusavitarne, TASER involves the removal of large polyps in the rectum without major surgery. This technique has gained both national and international interest.

Surgical Robotics Research Programme

The Surgical Robotics Research Programme was launched in 2017 and is being explored for certain types of bowel surgery. Moreover, this programme is providing St Mark’s distinguished surgeons with the opportunity to train on an advanced surgical platform.
