A 4-year-old left-behind boy was sent to our hospital after he accidentally fell while playing and had a bamboo slice inserted into his orbit from his upper lid. Since then, there was constant pus flowing from the wound, which lasted for nearly 1 month, and recently there were 3 bamboo sticks draining from the wound on their own. On ultrasound examination, there was a hyperechoic foreign body in the orbit; on CT examination, there was a large high-density shadow above the orbit near the optic nerve and the skull; and the child already had symptoms of protruding eyes and strabismus. Based on the history and examination, early foreign body removal in an anti-inflammatory situation was our protocol. However, it was very difficult: first, because the bamboo stick was in the posterior segment of the orbit, it was very difficult to separate and expose it, and we developed 2 surgical approaches, internal and external, on how to probe the location of the foreign body; second, because the foreign body had been retained in the orbit for too long and had been encapsulated and embedded, it was definitely difficult to remove it smoothly, so we prepared a variety of instruments, including microscopic probing instruments; furthermore, the foreign body was deep in the posterior segment of the orbit and We analyzed how to remove it without damaging these tissues and designed a relatively safe inferior and internal rotation position; the surgery started and found a deep fistula along the wound with a huge pus cavity at the bottom, which was very difficult to expose, and the foreign body was still missing even after the internal incision had reached the ball; the only feasible method was to explore it along the way, and we used a variety of instruments in turn. We used a variety of instruments, surgical forceps, straight forceps, and straight hooks to enter the fistula several times, probing for sensation toward the location of the foreign body on the CT film, and finally, a tactile sensation from a hard foreign body was felt slightly lateral to the orbital floor, which, if not incorrectly estimated, was several bamboo sticks scattered but inserted straight into the retrobulbar tissue. Switching to straight forceps, the bamboo sticks were opened and clamped and then carefully dragged out, and then probed to find a new bamboo stick removed …… The procedure that followed not only stunned me and my assistant, but even the anesthesiologist and nurse grew mouths and kept videoing …… Throughout, we took out 24 bamboo sticks, large and small, probably due to long-term inflammatory corrosion —- The sticks shattered and 2ml of pus was also removed! Considering the possibility of tiny bamboo sticks remaining after the surgery, we left the fistula untreated and sutured for the time being and prepared to perform the fistula repair again after ultrasound and CT review to confirm that there were no foreign bodies. At the end of the surgery, my heart still ached a little, how many accidental injuries could have actually been avoided, if these young children had parental supervision and care day and night!
