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
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 dissolving of small intestine and other abdominal organs that cause complications such as small bowel obstruction (laparoscopic adhesiolysis)
- Laparoscopic surgery of diverticular disease (resection of sigmoid diverticulitis)
- 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.
- Conventional and laparoscopic surgery for chronic inflammatory bowel diseases in Crohn's disease and ulcerative colitis (CED).
- Splenic diseases: Laparoscopic splenectomy
Colorectal surgery (surgery on the colon and rectum)
- Laparoscopic sigmoid resection (colon surgery) for sigmoid diverticulitis
- Laparoscopic colon and rectal surgery with systemic lymphadenectomy of colon and rectal cancer
- Conventional and laparoscopic surgery for chronic inflammatory bowel disease in Crohn's disease and ulcerative colitis (CED)
- Laparoscopic rectal prolapse surgery
- Transanal endoscopcic surgery using the “TEM” technique or the GelPoint Path Transanal Access Plattform to remove large rectal polyps and in certain cases confined rectal tumors ( small early rectal cancer)

Further Videos regarding TEM in giant polyps, rectal strictures and small rectal carcinoma can be seen in Transanal endoscopic microsurgery (TEM) part 02 to 07
- Haemorrhoids by conventional surgery and stapler haemorrhoidopexy (surgery according to Longo)
- Anal fistula surgery
- Sinus pilonidalis surgery (minimally invasive)
- Transanal rectocele and rectal prolapse surgery for defecation disorders
Laparoscopic sleeve gastrectomy, gastric bypass surgery and conversion of sleeve gastrectomy
- Conventional and endoscopically assisted thyroid operation
- Conventional parathyroid surgery
- Laparoscopic adrenal gland surgery

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.
