Profile

About Assoc. Prof. İsmail Ahmet Bilgin, MD

Assoc. Prof. İsmail Ahmet Bilgin, MD is a General Surgery specialist at Acibadem Maslak Hospital in İstanbul, where he works within the Bariatric & Metabolic Surgery and General Surgery units. His clinical work centers on the treatment of hemorrhoids and anorectal diseases, robotic surgery, and digestive system diseases and surgery. He has been in medicine for more than 19 years.

Dr. Bilgin graduated from Uludağ University Faculty of Medicine in 2007 and completed his General Surgery training at İstanbul University Cerrahpaşa Faculty of Medicine in 2014. Early in his career he worked at Doğubeyazıt No. 1 Health Center (2007–2008) and in the Department of Emergency Medicine at Şişli Etfal Training and Research Hospital (2008–2009). After completing his surgical training, he served in the Department of General Surgery at Muradiye State Hospital from 2014 to 2015 and joined Acıbadem Healthcare Services in 2015.

Clinical focus

Dr. Bilgin assesses and treats a range of anorectal and digestive system conditions. His areas of expertise include hemorrhoid treatment, anal fissure treatment and the management of other anorectal diseases, as well as digestive system surgery and the repair of umbilical hernia. He also treats inflammatory bowel disease, including Crohn’s disease and ulcerative colitis, in patients for whom a surgical opinion is needed.

In the field of bariatric and metabolic surgery, Dr. Bilgin performs obesity surgery, including gastric bypass. Robotic surgery is a further focus of his work. He has co-authored peer-reviewed publications on robotic and laparoscopic approaches in colorectal surgery, including complete mesocolic excision for colon cancer, robotic versus laparoscopic surgery for rectal cancer, robotic total proctocolectomy for ulcerative colitis, robotic and laparoscopic inguinal hernia repair, and robotic versus laparoscopic sleeve gastrectomy. His publications also address early postoperative complications in Crohn’s disease and the management of jejunoileal diverticulosis. Whether a robotic, laparoscopic or open approach is suitable depends on the individual patient’s condition and is considered during assessment rather than decided in advance.

How Dr. Bilgin works with international patients

Dr. Bilgin consults in Turkish and English, and interpreters can be arranged for patients who speak other languages. The Acibadem international patient team coordinates the collection of prior reports and imaging — for example MRI, CT, X-ray or ultrasound reports, laboratory and pathology results, operative notes and discharge summaries — and arranges appointments and the hospital visit. A first consultation typically covers the patient’s history and symptoms, a review of existing imaging and previous treatments, a clinical examination and a discussion of the available options. Video consultations are available for international patients who wish to discuss their situation with Dr. Bilgin before deciding whether to travel; a physical examination and any further tests would then take place in person at the hospital.
