Professor Dr. Samir Said, MD (University of Berlin, Charité)

Professor of general, visceral, vascular surgery, proctologist and advanced minimal access surgeon

After the co-development of the Transanal Endo­scop­ic Micro­surgery “TEM” at the beginning of the nineties and the subsequent establishment of the Mini­mal Inva­sive Surgery “MIS” in the abdomen and chest at the University of Cologne, Minimal Invasive Surgery  has  since become my clinical and scientific focus throughout my further career.

At the end of the 1980s and beginning of the 1990s, as part of my doctoral work, I had the opportunity to contri­bute to the develop­ment of the transanal endo­scop­ish microsurgery system, which is used in inter­disci­plinary appli­cations all over the world.

This has resulted in me being the main surgeon with the highest clinical experience in transanal endo­scopic micro­surgery for the removal of large polyps and small cancerous tumours in the rectum without an abdominal incision for many years in Cologne, Berlin, Koblenz and the surrounding area.

As part of my post­doctoral thesis (habilitation work) I deve­loped different lapar­oscopic instru­ments and a new minimally invasive surgical technique on the aortoiliac arteries in the 1990s.

Main surgical focus

Main surgical focus

Open abdominal surgery

All operations by means of open abdominal surgery with optimised peri­opera­tive care according to the "ERAS" (enhanced recovery after surgery) method. Essential elements of "ERAS" are: Gentle opera­tion technique, opti­mal oral nutrition management­ment, optimal and targeted pain therapy, modern anaesthesia methods, early and conse­quent reha­bili­tation after surgery.

Minimally invasive surgery

  • Laparo­scopic hiato­plasty with and without re-inforcement according to the BICORN technique
  • Laparo­scopic appendectomy 
  • Laparo­scopic gall­bladder removal (cholecystec­tomy)
  • Laparo­scopic inguinal hernia operation (TAPP)
  • Laparo­scopic and con­ven­tional (via open surgery) incisional hernia repair with mesh re-inforce­ment

  • Laparo­scopic onco­logical surgery of the large intestine (colon) and rectum with sys­tematic lymph­node dis­section (removal of lymphnodes) according to international cancer related criterias (onco­logical colo­rectal surgery)
  • Transanal endo­scopic micro­surgery for removal of large rectal polyps and small cancer tumours (rectal carcinoma) without open or laparo­scopic surgery.

Pioneering in the surgical field

Pioneering in the surgical field

At the end of the eighties and the beginning of the nineties, I had the opportunity to help develop the transanal endo­scopic microsurgery system as part of my doctoral thesis.

Both in Cologne, Berlin, Koblenz and surrounding areas, I was the surgeon with the highest clini­cal experience in transanal endo­scopi­scopy “TEM” surgery.

As part of my post­doctoral thesis in the nineties I had deve­loped different laparo­scopic instru­ments and a new laparo­scopic ab­dominal aortoiliac opera­tion technique.
