Marius is on the Specialist Register as General Surgeon and his subspecialty practice is in Colorectal Surgery. He trained in Mersey Deanery, has a Diploma in Laparoscopic Surgery from the University of Strasbourg and European Institute of Telesurgery and also completed short visiting residency training in Laparoscopic Colorectal Surgery at the prestigious Cleveland Clinic, Ohio, USA. Over the years Marius has pursued a specialist interest in minimally invasive surgery. In the area of General Surgery he performs routinely laparoscopic cholecystectomies (key hole surgery to remove the gallbladder), diagnostic laparascopies and has an interest in keyhole surgery for the treatment of hernias.

In the field of Colorectal Surgery, Marius has introduced in the Trust the laparoscopic (keyhole) surgery to for the treatment of benign bowel conditions (Crohn’s disease, colitis, rectal prolapse) and bowel cancer. He has also introduced the Transanal Endoscopic Microsurgery, a modern surgical treatment of rectal polyps or early rectal cancers which avoids major surgery. Marius has developed expertise in colonoscopy and treatment of large bowel polyps using special procedures performed with the help of the colonoscope, being able by this to provide the full range of Minimally Invasive Colorectal service. His practice comprises equally the major surgery for rectal and colon cancer.

Marius has introduced in the Trust a very efficient rectal bleeding service. This is a Choose and Book service where most of the patients having this very common problem are seen, investigated and treated in one single visit. Marius supports the General Practitioners and the local community by doing domiciliary visits when necessary.

Marius is a keen teacher and has developed a Trust Training and Education website for junior doctors, gives lectures and teaches practical skills fundamental to the development of a competent doctor. He lectures by invitation to patients associations.
