Fish
dishes and me
Eating fish carelessly may lead to a serious
disease requiring a surgery.
I (Dr.
Tokuda) like fish dishes, especially sashimi. And among variety of
assortment of sashimi, I like tuna and salmon, a lot. My father is a
former fisherman. In Okinawa, fishermen are called ‘Uminchu’ (meaning people of
the sea). As a child, I used to eat fish frequently.
However,
there are two fish dishes I don’t like. These are one whole fish either
broiled or grilled with all its meat and bone. The reason I dislike whole fish
when I was young, is to go back to my elementary school days.
One
night, the very first catch of my father was our meal for that supper. When I
was eating my supper, suddenly, my throat hurt. I spurted out the fish
meat from my mouth, and a small fish bone came out.
Since
then I have been able to improve the skill of eating a whole fish dish by
completely removing fish bone with chopsticks. Since fish dishes served every
day in my family, it was considerably a good training for me.
I
learned my lesson because I felt intuitively that in every child's heart knows
that "I will get harm seriously if I swallow the fish bone, even if I make
a mistake accidentally. This is some sort of a protective mechanism inherent in
every child.
Fish
bones and me
Several
years later, I looked up the textbook on fish bones during my medical
student 's years at the University of the Ryukyus, and I could no longer find a
concrete answer to the question of: “What will happen if I swallow the bones of
the fish?"
However,
during my residency at Okinawa Chubu Hospital, I was responsible for medical
treatment in the Emergency Room. Coincidentally,
I came across, once again the "fish
bone" I experienced in my elementary school years, and this time a patient
at the hospital.
I was in
a doctor’s consultation room with a patient with a chief complaint: "My throat
hurts suddenly when I was eating fish." I knew right away the diagnosis:
fish bone stuck in the throat. The senior resident who had several cases of
fish bone showed me how to take out a fish
bone stuck in patient’s throat with a use of small scissors-like instrument called
"Kansi". The fish bone was taken out and glad to see the patient on
the road to recovery and will get well soon without complications.
After
that, I was in charge of a male patient with an abscess in the abdominal cavity.
The etiology (cause) of abscess was unknown at that moment. The patient
complaint of abdominal pain; and had fever. Ultrasound and CT scan
examinations were ordered. The initial impression/suspicion before surgical
operation, there was a foreign body in the abscess area. Sure enough, the
"fish bone" was found during laparotomy surgery. The diagnosis was
"fish bone abscess"; length of the fish bone was of several
centimeters and was removed together with the abscess. The patient fully
recovered after surgical and medical treatment.
This
case was presented at the Medical Society of Okinawa Prefecture around 1990.
The presentation was like patterned after Clinical Pathological Conference
(CPC). The case which I presented at a formal conference was entitled: “Fish
osseous abscess".
Pierced
abscess by fish bone
To
swallow fish bone is dangerous to the body.
The
first reported case of abdominal disorder due to fish bone in the world was
in 1842, with the fish bone penetrating the stomach stuck in the vein of
the viscera, resulting in severe phlebitis.
Many of
the fishbone diseases reported later are from Asia. The bones of the fish
caught in the vicinity of Asia are small and it is "easy to swallow".
In the 1980s, Queen Mary Hospital in Hong Kong reported 117 cases of fish bone
disease.
"Swallowed"
fish bones penetrate like piercing various organs and tissues in the body. When
penetrating at the pharynx, cervical abscess or thyroid abscess occurs, and
when penetrating through the esophagus, it causes mediastinitis. Penetration
through the stomach and duodenum leads to liver abscess and phlebitis of
internal organs. The bone of fish
accompanying
bacteria in the oral cavity creates pus from the bacteria.
Diagnosis,
treatment, and prevention of fish bone abscess diseases
Fish
bones do not appear in simple radiographs (x-ray). It is therefore, the
diagnosis is surprisingly difficult. Recently, it became possible to diagnose with
CT with angle changing part by constructing CT image in three dimensions, which
brings about the advancement of diagnosis.
Treatment
is surgery. In the future, we may expect laparoscopic surgery. With antibiotics
alone, abscess due to "foreign body" cannot be cured.
The most
important thing is prevention. As fish cuisine comes out as I do it, standing
up, and look carefully like you are in a three-dimension level, and remove
the dangerous bones. For elderly people with cataracts and hyperopia, weak
eyes, etc. it is better to avoid a “fishy"
fish dishes. I would like you to follow my favorite sashimi system, mentioned
in the beginning of this article. Because fish dishes are healthy and tasty.
