About Mr Ivan Tomasi

Mr. Ivan Tomasi is an accomplished General Surgical Consultant. He obtained his medical qualification in 2000 and went on to complete his surgical training with honours at the School of General Surgery at Verona University in Italy in 2006.

Following his training, Mr. Tomasi gained valuable experience as a Colorectal Senior Clinical Fellow at Barts for two years. He also worked as a Locum Consultant in Emergency Surgery with a subspecialty in Colorectal surgery at Rotherham and Watford.

In 2015, Mr. Tomasi was appointed as a Consultant in Emergency General Surgery at Guys and St Thomas Hospital in London. He has actively participated in research, particularly in collaboration with the University of Southern California and Cedars Sinai Hospital in Los Angeles, USA, focusing on new oncological markers. His contributions to the field include published scientific articles and numerous presentations at national and international meetings, with a specific focus on oncological markers and the treatment of conditions such as haemorrhoids. Mr. Tomasi's dedication to medical education has earned him the distinction of being an Honorary Senior Clinical Lecturer at King's College London (KCL).

His elective practice primarily involves procedures related to abdominal-inguinal hernia repair, proctology (including haemorrhoids, anal fissure, fistula-in-ano, and pilonidal sinus), abdominal wall reconstruction (AWR), laparoscopic cholecystectomy, and the management of lumps and bumps.

In addition to his clinical roles, Mr. Tomasi has also taken on leadership positions. He served as the audit lead for general surgery for four years and currently leads initiatives related to sepsis and infection control. Prior to his consultancy at Guy's and St Thomas' NHS Foundation Trust, he devoted his expertise as a volunteer doctor in a rural hospital in Burundi, Africa, in 2005.

Mr. Tomasi handled my abscess drainage superbly. He explained very clearly the process, the aftercare and managed the pain well.

Mr Tomasi, was brilliant in quickly picking up my case after I struggled to receive adequate treatment at a different hospital. His ability to quickly react to the situation and arrange appropriate care meant that I received treatment extremely quickly. His ability to calmly and expertly explain both the surgery required, and the process itself, alongside detailed aftercare immediately put me at ease. I would highly recommend him both for his deep level of expertise, but also for his caring nature and personality. He clearly cares about his patients and I have no doubt that without his help and support, I may not have survived to write this review. Highly recommended.

Dear St Thomas'Hospital Team, I would like to express my sincere gratitude to St Thomas'Hospital who cared for me. On Tuesday evening, I went to work for my night shift at around 9 p.m. Unfortunately, I became unwell and my colleagues called an ambulance. I was taken to St Thomas'Hospital where I received excellent care. The ambulance crews were very professional, kind and caring, and I would like to thank them very much.A around 7.00-8.00 a.m. I met Dr Ivan Tomasi. I was very impressed by his professionalism, kindness and dedication. If I had to give him a score to 1-10, I would give him 10 without hesitation. After my operation, everything went well, and I was very pleased with the care and the supervision provided by the Dr Ivan Tomasi and the whole medical team. I would like to say a very big thank to all the staff at St Thomas'Hospital for their professionalism, care and kindness during a difficult time for me. You're all doing an amazing job, and I'm truly grateful for you have done for me. God bless you all, and thank you from the bottom of my heart. With my deepest gratitude Mihai I.

Ivan Tomasi was the most amazing surgeon I could have asked for, from my initial suffering of appendicitis to showing me compassion and kindness and offering me the antibiotic route with elective surgery to follow. The surgery was painless and the after care was amazing, took the time to walk me through everything. Ivan Tomasi calmed me and made the experience so pleasant from start to finish.

Some heroes wear capes. Mine wears scrubs! Mr Tomasi is an absolute hero, truly heaven sent! Not only did he save my life, but he also managed to put my family completely at ease while doing so. He is a genuinely caring, compassionate, honest, trustworthy, and warm surgeon. Unknown to him, my family and I had recently suffered immense grief, losing my father to pancreatic cancer followed by, and completely unexpectedly, my maternal grandmother just four days later. With other ongoing health battles and cancer diagnoses within our immediate family, we were left shaken and terrified of anything hospital-related. On top of this, I suffer from a severe autoimmune disease (diffuse systemic sclerosis) which affects multiple organs, including my heart and lungs. I arrived at St Thomas' Hospital via ambulance, vomiting and in immense pain. Tests revealed a small bowel obstruction, and I was admitted to the ward, which is where I met Mr Tomasi. At our first interaction, I asked him to be completely open and honest with me, even if the news was tough. He always was. Because surgery posed a heightened risk to my organs, we initially decided a non-invasive plan would be best. Throughout it all, Mr Tomasi ensured my family and I were kept informed at every single stage. Unfortunately, the conservative treatment did not work as hoped, and I required urgent surgical intervention. Mr Tomasi spoke with me in great detail about the procedure, the risks, and what to expect. To say I was nervous is a massive understatement, but I felt entirely safe in his care. He arranged the surgical team fo...
