Endocrinologists abroad

I am very pleased with the communication of my doctor Adnan Bey, with clear answers to my [questions].

This is my second operation with Dr. Adnan. Thank God for giving us this doctor.

In 2009, our mother was found to have a mass in her breast. The doctor helped to diagnose it as accurately as possible, successfully performed breast-conserving surgery, and competently organized the entire treatment process.
During regular follow-up examinations, he always showed patience, attention, and support. We have boundless trust in his professionalism and are very grateful to him.

I met our dear Dr. Adnan Bey after coming from Bolu, and underwent gallbladder removal surgery at the American Hospital in Istanbul. This was back in 1995, when laparoscopic operations were just beginning to be performed.
Now I am 57 years old and have no health problems. Later, my daughter underwent a similar operation, after which we had complications and additional procedures were needed. I am still very grateful to our doctor for his help and support.

17/03/2015

The doctor performed thyroid surgery on my wife. Many people consider such operations simple, but in fact they can be quite complex and risky depending on the situation.
In our case, everything went well. We thank the doctor for his professionalism, patience, and attentive attitude. We can confidently recommend him to other patients.

28/01/2015

After thyroid nodules were found in my mother and a doubtful biopsy result, we started looking for a specialist to perform a total thyroidectomy. That's how we found this doctor.
After the operation at Medical Park, my mother had no complications that we were very afraid of — neither voice problems nor damage to the parathyroid glands. The very next day, she could speak and eat normally.
A very experienced specialist whom I can confidently recommend for thyroid surgery.

Dear Fatih Hocam, every time I remember him, I pray and smile — I have never met such a delicate doctor in the world. I was diagnosed with "papillary thyroid cancer," I consulted four different doctors, but inside there was panic and I cried all the time, because all members of my family were taken by cancer. Fatih Hocam calmed me down psychologically, explained the entire operation from beginning to end, and performed it. The operation was very successful — the next day I was able to go to work, there was no pain at all, and no scar from the operation remained. I thank Dr. Gokhan, who strongly recommended Fatih Hocam to me.

The doctor performed surgery on my wife for Graves' disease (related to thyroid hormones).

After that day, I clearly understood that what I had experienced was abnormal. I am now 36 years old, and still, when remembering, I pray for Fatih Bey in my prayers. I consider it my duty to return the gratitude that I could not express then. As a surgeon, he is a master of his craft; I believe no one can compare with him. I ask God that his deeds be successful, his words clear, and that he live a long life in good health.

Dr. Fatih Tunca operated on my sister for papillary thyroid cancer. I myself have worked in the healthcare system for many years and can say that he is a true professional. He listens very attentively to both the patient and relatives, explains the entire treatment process in detail, and answers all questions. He inspires great confidence and helps to cope with fear. We are very grateful to him.

If you are facing thyroid surgery, you are probably worried about questions: will my voice change, will the parathyroid glands be affected, will there be a large scar, and will I be able to completely get rid of the disease. I went through this too. Fortunately, I met Professor Fatih Tunca. A very experienced and attentive doctor who explains everything in detail and gives the patient a sense of calm. He operated on me the day after the consultation, and none of my fears came true. Only 4 days have passed since the operation, and I feel great, and the scar already looks very neat. Many thanks to the doctor.

27/02/2023

My thyroid complaints became so severe that I was afraid to fall asleep at night. I was very lucky to meet Dr. Fatih Tunca. First, he explained in detail everything that worried me, and then quickly helped solve the problem. 4 days ago I had surgery: one nodule was 4 cm, others — 3 and 2 cm, in addition to many other nodules. Now my pain, palpitations, and other symptoms have completely disappeared. Despite the fact that only a few days have passed since the operation, I feel great. He is not only a brilliant specialist, but also a very humane doctor.

01/02/2023

When I was diagnosed with pheochromocytoma, I was in panic and didn't know what to do. That's when I met Dr. Fatih Tunca. He explained everything very thoroughly and calmly, thanks to which I felt much more confident. The operation was successful. The doctor always patiently answered my questions and was attentive to me both before and after the operation. I am very grateful to him for his support and professionalism.

19/12/2022

I am 24 years old, a vocal teacher, and the diagnosis of multinodular thyroid disease scared me very much. In Gaziantep, I went around many doctors and hospitals until I met Fatih Tunca. After that, the whole process became much calmer. He is a very delicate, understanding, and trust-inspiring doctor. It is now the fifth day after the operation, and the scar on my neck turned out to be much smaller than I expected. I worried most about my voice because of my profession, but I had no problems with vocal cords or calcium. Many thanks to the doctor.

21/08/2022

When I was diagnosed with papillary thyroid cancer, I was very frightened. I consulted four different doctors, constantly cried and worried, because I lost many relatives to cancer. Dr. Fatih Tunca was able to calm me down psychologically, explained the operation in detail, and successfully performed it. The very next day I had so much energy that I could go to work. There was almost no pain, and the scar is barely noticeable. He is a doctor you can fully trust.

05/08/2022

In 2021, I consulted a doctor due to severe hair loss, and I was advised to check the thyroid gland. Later I was diagnosed with Graves' disease. Over time, severe weakness, irritability, heat intolerance, hand tremors, and eye problems appeared. Several doctors recommended surgery, but were waiting for the right moment. In March 2022, I was referred to Fatih Tunca. Already at the first consultation, I felt how attentively he treats patients. He explained the treatment in detail and openly, after which I immediately decided to be operated on by him. On March 21, my thyroid was removed. After the operation, no complications arose, and my voice did not change at all. After 15 days, I returned to work and feel great. I am very grateful to the doctor and consider it great luck to meet such a specialist.

06/04/2022

16 years ago, Fatih Tunca performed gallbladder surgery on me. This person occupies a special place in my life. Then he was not only an excellent surgeon, but also supported me as a person. Even after so many years, I remember him with gratitude and pray for him. As a specialist, he is a true professional, and as a person — very kind and fair. I wish him health and many years of life.

24/11/2021

Thank you very much. I successfully had surgery for gallstones and umbilical hernia. You inspired confidence in me. You supported my morale. You were very attentive before and after the operation. I can recommend you to everyone.

A very polite and attentive doctor. Thanks to him, I underwent thyroid surgery very easily. Thank you, health to his hands.

You don't always meet such a successful and smiling doctor in life. I had fears, but even before meeting him I had already overcome them all, and I had a very successful operation. Many thanks to Dr. Nuri Alper Sahbaz and his team. It's good that you exist.

A very attentive and friendly doctor. Thanks to him, I underwent thyroid surgery very easily. Many thanks for your work and care.

12/12/2021

I had thyroid cancer and there was a risk of losing my voice. Thanks to Professor Alper, I was able to recover quickly and return to normal life. Many thanks for your work and professionalism.

11/06/2020

The doctor attentively accompanied me from the moment of preparation for the operation until discharge from the hospital. He is a wonderful specialist and a very good person. The operation was extremely complex and lasted more than 8 hours — from 08:00 to 16:30. I want to thank Dr. Alper and the entire surgical team many times. I had a total thyroidectomy and neck dissection — one of the most complex operations in the head and neck area. After the operation, recovery is going very fast. Thank you for your professionalism and attentive attitude.

18/03/2020

Thank you very much. I had a successful operation to remove the gallbladder and treat an umbilical hernia. You instilled confidence in me and supported me morally. You treated me very attentively before and after the operation. I am happy to recommend you to other patients.

09/03/2026

Very pleased with the treatment. The operation went successfully and calmly thanks to the doctor's clear explanations. I also note the high level of service and attentiveness.

I had thyroid surgery at the hospital. From the appointment onwards, everything was at a very high level — nurses, staff, cleanliness of the rooms — everything was excellent. The doctor explained everything in detail before the operation, calmly answered all questions. After the operation, I quickly recovered, my voice was preserved. Very pleased with the result and grateful to the entire team.

24/02/2026

Recently I had gallbladder surgery at Medicana Beylikdüzü with Doctor Ozan Akinci. During the operation, I was informed that a growth was found in my stomach.
However, this was said when I had not fully recovered from the anesthesia and could not properly ask questions. The shock and anxiety were strong.
When I tried to get information later, the doctor was difficult to find. The information was passed to me through a familiar doctor.
The next day, when I asked questions before discharge, I did not receive calm and understandable explanations. Phrases like "give a percentage or numbers?" only increased my anxiety.
When asked why a biopsy was not taken, the answer was: "could have taken it, could have not — didn't take it". When asked about the sutures, the doctor said he didn't remember what he sewed with.
Also after the operation I was told that the dressing could be done at home, although usually this is done in the hospital. Later I was even told to complain anywhere I want.
I don't want to blame anyone, perhaps the treatment was correct. But what's important is not only the operation, but also the attitude and communication with the patient.
Especially in a stressful situation, more calm and empathetic communication was expected.

14/01/2026

Two days ago I had surgery. Throughout the entire process, Doctor Ozan Bey and Batuhan Bey helped me a lot.
Everything went very well, I felt safe and calm. The hospital is very clean, the staff very friendly.

Erhan is a very experienced and very good surgeon in his field. He performed surgery on me to remove a nodule of the left lobe of my thyroid gland and it was successful. He is a positive person who helps me to think positively.

26/03/2024

I had parathyroid surgery about 4 years ago, the adenoma could not be removed, I had to have a second surgery, but as with any surgery, the second surgery was very risky and I could not find the courage to have this surgery. During this 4 year period I experienced a lot of pain, both physical and mental. Until I met Erhan through the internet. I followed his posts, participated in his live broadcasts, asked questions and imagine, he didn't leave any of my questions unanswered, this surprised me a lot and inevitably my confidence came back and I decided to contact this doctor; when I said I want to come to you and do the surgery but can't overcome my fear, he told me, don't be afraid, you can overcome your fears once you get past them, this was the light at the end of the tunnel for me. Without wasting any time, I took my plane tickets and went to see him. And so on 03.09.2022 I regained my health with a successful surgery. The surgery lasted about 1.5 hours (here I should clarify that Erhan went for the surgery only after looking at the ultrasound result and the 4 year old scintigraphy report). I will not explain here the experience of my teacher and his international successes. I will summarize. God who gives the problem also gives the cure. Erhan became my cure.

5/09/2022

The doctors I went to in my city refused to do my surgery for various reasons. One doctor I found out of town even said that the surgery would take 12 hours (!), that I was in a very serious condition and that I was unlikely to survive. Luckily, I found Dr. Erhan and he told me everything about my illness, all the details of the disease and that he could do my surgery in 3-4 hours. He is a very professional and knowledgeable doctor as he has done thyroid and parathyroid surgeries many times, he is very knowledgeable and has seen many cases so he is very knowledgeable in his field. If you have thyroid problems, don't hesitate to contact him, no matter what city you are in, come to Yeditepe Kosuyolu Hospital and restore your health in the capable hands of Dr. Erhan. Erhan saved my life, thank you so much for giving me the opportunity to live beautiful days.

22/05/2022

On October 26, a thyroid ultrasound showed an enlarged nodule, a biopsy was performed and when the biopsy result was suspicious, I was told that surgery was necessary. The thought of surgery kept me in suspense until I spoke to Erhan Aysan. He reassured me and said there was nothing to be afraid of. On November 13, I underwent a bilateral total thyroidectomy and after the surgery I was not hoarse at all and the scar was minimal. Now, looking at the scar, it is not even clear that I underwent surgery. In short, you can put your trust in Dr. Erhan. I am eternally grateful to you, I am glad to have you.

26/11/2021

When I came to see Dr. Erhan, he greeted me very friendly and talked to me and my family in detail about my disease, after this interview I decided to have the surgery. I was very worried about hoarseness in my voice and parathyroid gland damage, but thank God thanks to Dr. Erhan there was no hoarseness in my voice and no parathyroid gland damage. Thank you very much.

19/11/2021

As soon as I was diagnosed with thyroid cancer, after finding out my family history, examining all family members, identifying 2nd case and cases requiring follow up, he saved my life.... A doctor who does his job with meticulousness and instills endless confidence.

25/05/2021

In addition to being an excellent surgeon, he is also a wonderful person. He performed thyroid surgery on my wife. He answered all the questions we asked before surgery with a smile and addressed our concerns. The nodules formed by the thyroid gland were narrowing the windpipe. It would have been a complicated surgery, possibly having to open up the chest. But thanks to Mr. Erhan, this was not necessary. Although we were discharged on Sunday, he personally came in the morning and did the final checks. We thank him once again. I am glad to have him here.

24/04/2021

Professor Stern saved my life! A caring doctor with a kind heart! 26/11/2019

Professor Stern guided me for 6 years with full dedication and care. Professor Stern cares more about his patients than any other doctor I have ever known. The nurses are kind and helpful. Cozy and comfortable welcome. Always dedicated and always caring. 14/10/2017

I recommend the endocrine department in Ichilov.

Good online consultation and I will go for further examination.

Dr. Ercan has been our physician for 8 years with our 3 children. She is truly a knowledgeable specialist. You can reach out to her at any time and receive her attention and all the necessary information. She even remembers past details about the child that we don't remember, which clearly shows that she genuinely loves her work and children. We are fortunate to have such doctors.

We had a very good experience at Memorial hospital, the staff was kind and helpful. But we want to send special thanks to child endocrinology Prof. Dr. Oya Ercan. She is so professional, and we trust her till the end. Also, Dr. Burak Emre Aydin was so careful with our child and did his job very well. Thank you so much. Many regards :)

We visited Dr. Oya Ercan at the Memorial Clinic regarding growth problems of our 8-year-old son. Dr. Ercan conducted a thorough examination, including tests and scans. She listened to our concerns very attentively and explained the situation in detail. The prescribed treatment gave good results - our son grew significantly within a year. We are grateful to Dr. Ercan for her professionalism and sensitive attitude towards young patients.

We have been seeing Dr. Oya Ercan for three years. She monitors our daughter with type 1 diabetes. Dr. Ercan is a true professional. She is always available for consultations, patiently answers all questions, and gives clear recommendations on disease management. Thanks to her competent approach, we manage to maintain stable blood sugar levels in our child. We are very pleased to have found this doctor at the Memorial Clinic.
