A small health center is located in Velingara, Senegal. It is approximately 7 o’clock in the morning. In the old, dusty room that constitutes the operating room, a soft beeping sound, like that of a kettle, begins to be heard between the rhythmic beats of the heart monitor. The oxygen cylinder has started to leak.Calmly, one of us approaches and applies Teflon, controlling the problem. After a while, the electrical current is cut off .Undeterred, the anesthesiologist continues to hand ventilate the patient with her ambu, and we all turn on our headlamps.There is no more electric scalpel, but the activity does not stop.

Outside it must be around 35 degrees. Under our surgical gowns and without ventilation, the wind chill is much higher.From time to time, our colleagues wipe away the sweat with cloths, and in passing, they keep away the flies that swarm over the surgical field. However, the activity does not stop.

While we operate, one of us consults in a small cubicle located a few meters away from the operating room. Dozens of patients wait in line to be seen. Many do not speak English or French, only local dialects. Gestures are of paramount importance. In the end, we manage to communicate. It is a question of will. And trust.

Children do not cry. They are tough, resigned children.They take our hands and come to the operating room without complaining. There is no room for tantrums in their lives. A few hours after surgery, they return home, even after major interventions. There is no other option for them.

One of the days, I go out to buy something to eat. I find a small stall and see some cheese triangles that catch my eye.I point them out to the salesclerk. To my amazement, she opens the box and offers me one. I tell her I want the whole box, and she does not believe me. I still have a hard time processing that when I go to the supermarket here in my neighbourhood (Fig. 1).

The fatigue, at the end of the expedition, is twofold. Physical fatigue: 12 h operating a day for a week wears anyone out, especially in these precarious conditions. But above all,the greatest weight is due to emotional fatigue. Some of our patients have to borrow money to pay for transportation to our work centre. Others have to sell their animals, or even their homes. There is no other option for them. In many cases, we are faced with catastrophic situations in which our ability to solve is non-existent. Even with banal pathologies. It is difficult to overcome emotionally and humanly the experience of this fact. It is difficult to overcome the perpetual misery, the fact of not being able to give enough,of not having anything better to give them.

And we feel sadness. Sadness for having to leave. Sadness for what remains unresolved.

We promise to come back the following year. They hug us and thank us. We feel it is a genuine, heartfelt thank you.And before we set foot on our land again, we are already thinking about the next expedition.

However, not everything is pejorative. The smile of the parents of a girl with a cleft lip when they see her face after the operation. Or the smile of a child when he sees that he no longer has a hernia and that he can play soccer without getting hurt, and without being singled out. The smile of the little girl who can move her arm again after years of immobilization due to the after-effects of a burn. The warm welcome of the whole community, and above all, the feeling of home. Because in Africa, we did not find a job: we found a home (Fig. 1).

We became doctors to help our patients. To cure, but also to alleviate their suffering and to accompany them when they need it. And if there is one thing that fulfills this paradigm,it is international cooperation. While the development of new medical technologies and advances in research are vital for the development of our discipline towards quality care,we must not forget that a large part of the world's pediatric population does not have access to even the most basic health resources, with frequent deaths or serious morbidities secondary to banal pathologies [ 1- 4].

I am passing on this reflection from my experience as international cooperant with the aim of raising awareness and asking you to try it at least once in your life. It is a tough experience. It will undoubtedly put you on the ropes. It will make you rethink things that until now were practically dogmas for you. And this is hard to bear.

But I can guarantee you one thing: you will not regret it.
