Next they try to image what is going on in your belly. An
abdominal x-ray may detect the fecalith as the cause of
appendicitis (5%). Free air due to perforation can might be seen
on the plain film.
A barium enema may be used. It is an x-ray test where liquid
contrast is used from the anus to fill the colon. Sometimes it
show an impression on the colon in the area of inflamed
appendix. Barium enema also can exclude other intestinal
problems that mimic appendicitis.
Ultrasound shows an enlarged appendix or an abscess. Ultrasound
is painless, but the appendix can be seen in only half of
patients. Ultrasound also is helpful in excluding the problems
with ovaries, fallopian tubes and uterus. Ultrasound machine
usually looks like a small thumb on wheels that they bring into
your room. Technician puts gelly on and drives the probe over
you belly.
Often they go straight to CT Scan (computer tomography).
Especially if the patient is not pregnant. CT scan gives
relatively high irradiation of your body by x-rays. However
benefits of prompt diagnose of appendicitis outweigh the risk of
radiation. CT scan gives slicing images of your body.
What do they look for? As any inflamation causes edema, the wall
of the appendix will be thickened. This is actually a defensive
mechanism - by edema the organism try to wall of, to seal off
the area of infection and inflamation.
But it is useful for us because we can surely say there is an
inflammation. The same goes for ultrasound.
CT scan is expensive - around 1000 dollars in an American
hospital, though 40 dollars in Russia.
If the CT scan is taken during the night, CT image may be send
to Australia Russia or India.
An American radiologist is paid around 40 dollars to read just
an X-ray film. I guess he gets more for reading the CT scan. It
is only 5 dollars in India. This is why even such clinics as
Harvard and Yale adopt this model of work - they send the CT
scans to the cheap labor abroad. Especially during the night.
Half an hour later the fax from Australia arrives. "Inflammatory
pericecal mass in the right iliac fossa consistent with the
diagnosis of severe acute appendicitis." Any doctor can read an
x-ray film or CT scan. Radiologists are doctors who specialize
in the reading of the films. They may find what was missed by
others.
At this point diagnosis is usually clear. In cases if it is not,
there is Laparoscopy. Laparoscopy is a surgical procedure. Small
fiberoptic tube with a camera is inserted into the abdomen
through a small puncture in abdominal wall.
Yet there is no test that will diagnose appendicitis with 100%
certainty.
The position of the appendix may vary. If it is longer than
normal, appendix may go deep down into the pelvis. It also may
move behind the colon (called a retro-caecal appendix). From one
hand it is better because retro-caecal appendix has less chances
to burst into peritoneal cavity, from the other it is difficult
to diagnose and it is difficult to approach surgically.
Inflammation of other organs, for example, female pelvic organs,
may resemble inflammation of the appendix. Pregnant women may
have appendix pushed up in abdomen by the enlarged uterus.
Athletic young adults may tolerate more pain and may have not so
obvious symptoms of appendicitis. Old patients may have vague
symptoms as well.
Other inflammatory problems may mimic appendicitis. Surgeons
often observe patients with suspected appendicitis for a period
of time to see if the problem will resolve or suggest
appendicitis more strongly versus another condition. Conditions
that mimic appendicitis are:
1) Meckel's diverticulitis. 2) Pelvic inflammatory disease
-infection of tube and ovary. It is treated with antibiotics
alone 3) Fluids from the right upper abdomen may drip into the
lower abdomen and cause inflammation resembling appendicitis.
Then, for example, patient has gallbladder disease or liver
abscess, but all symptoms suggest acute appendicitis. 4)
Diverticulitis that occur on the right side. 5) Inflammation of
right kidney. 6) Crohn's disease or ulcerative colitis 7)
Yersinia enterocolitica infection - the bacteria that comes form
certain food - like unpasteurized milk. - may cause appendicitis
8) passing kidney stone 9) ectopic pregnancy 10) ovarian cyst
rupture. And so on. There are some other conditions.
Appendectomy is performed urgently usually. Thomeo is Latin for
dissect or cut. Lapar - is abdomen (belly) in medical Latin.
Laparotomy is opening of belly. Appendectomy is cutting of
appendix. Laparoscopy is looking (by scope) into belly.
Antibiotics almost always are given prior to surgery as soon as
appendicitis is suspected.
Few patients have mild "confined appendicitis" localized to a
small area. These patients may improve during several days of
observation when treated with antibiotics alone. Doctors may or
may not removed the appendix later. Chances are you are not one
of this patients.
If a person has not seen doctor for many days while appendicitis
ruptured (yeah, sometime happens; there are some tough guys), an
abscess may form, and the perforation may close. Initially it
can be treated with antibiotics; however, that will require
drainage later. A drain is guided under ultrasound or CT scan
and appendix is removed after the abscess resolves.
In modern days surgeons offer laparoscopic appendectomy. They
insert laparoscope (it is like a small telescope with a video
camera) and remove appendix with special instruments through
small puncture wounds.
If you had this type of surgery, you will probably have four
1-cm size scars and you will go home in one or two days.
But if your case is complicated or there is just no laparoscopy
in the hospital, they will do classical appendectomy. Surgeon
cuts 10-cm incision in the area of the appendix. Appendix is
removed form the right lower abdomen or where it is. Area is
checked for other problems. In the case of abscess the purulent
stuff will be drained with rubber tubes through the skin. With
that kind of surgery you will probably stay for four to seven
days. Antibiotics will help to resolve the abscess.
This is why you sign the consent: "laparoscopic appendectomy,
possible conversion to an open appendectomy".
The most common complication of appendectomy is wound infection.
If it is severe, the surgeon will postpone incision closure for
several days.
Ok, now you have those four small scars or one big scar, you go
home and visit that party that you missed.
