Inflammatory Bowel Disease
by administering TPN for about five days. In a moderately
nourished patient, TPN use is controversial. Immunosup-
pressive agents should be stopped. However, studies suggest
that patients treated with biologicals within two months do
not have an increased risk of complication.

Steroids should
be administered if the patient has received steroids in the
past six months. Bowel preparation and antibiotics should
be given according to the individual institution’s protocol.
Institutions have varying protocol for cleaning the colon.
Options include giving an enema, Golytely, Miralax and
some other available agents.
Operative Procedures and Techniques:
If the abdomen is explored for Crohn’s disease, a physician
must examine the entire intestine, as there may be other
areas affected by the disease. Sometimes this can be a very
challenging task, especially in a patient who has undergone
multiple previous surgeries.
Laparoscopic or Open Technique:
The most common laparoscopic procedure performed in
Crohn’s disease is surgery of the ileocolic segment. Laparo-
scopic procedures in general have been shown to have better
cosmetic results, less post-operative pain and fewer adhesions
leading to less recurrence of obstruction, shorter post-oper-
ative ileus, a faster return to work and fewer post-operative
pulmonary complications. The duration of the hospital stay
depends on the extent and severity of the disease. However,
most of the studies prove that duration of the stay is short-
er with laparoscopic technique.

Hand assist devices have
further facilitated laparoscopic procedures. There are some
limiting factors for laparoscopic surgery.These include dense
adhesions, complex fistulas and abscesses, and severely ill and
unstable patients. Laparoscopic procedures do take longer
operative time. Surgeons experienced in laparoscopic surgery
have used single incision laparoscopic colectomy, as well. In
single incision procedures, ergonomics aremore difficult and
depend upon the surgeon’s level of training and confidence.
Obstruction:
The most common cause of obstruction is stricture for-
mation. In repeat surgery, adhesions can also be a factor. For
long or multiple strictures in close proximity, the choice of
procedure is resection and primary anastomosis. However,
in patients with short bowel syndrome, even with a long
stricture, a strictureplasty should be considered. Stricture-
plasty should also be considered if the patient has repeat
and frequent episodes of bowel obstruction. Short strictures,
even if multiple, can also be treated with strictureplasty. The
technique requires dividing the stricture area longitudinally
for about one to two centimeters proximal and distal to the
stricture and closing it transversely. Another technique is to
perform Finney type repair, in which a long incision is made
at the long segment of the stricture. This is then closed by
bringing the open loop in U shape and anastomosing the
opening in U shape.
A physician can use the Jaboulay type technique if the
stricture area is too long. This is to bring the large loop of
stricture area in U shape. Then making an opening just
proximal and distal to the stricture area and anastomosing
these side by side.
A third technique is a side-to-side isoperistalticMichelassi
strictureplasty. This is performed if there are multiple stric-
tures in a long segment. With this technique the diseased
bowel segment is isolated, a proximal loop is placed on top
of the distal loop in a side-to-side fashion, and they are
anastomosed in two layers. Balloon dilatation with balloon
catheter has sometimes been proven to be helpful in patients
with short bowel. Balloon dilatation has better outcomes in
patients with stricture fromprevious anastomosis. However,
balloon dilatation carries a risk of perforation, bleeding and
stricture reoccurrence. Recurrence, even after resection, can
be 30 percent at 10 years and can reach up to 50 percent over
a 15 year period.

Stricture can occur at a different location
and not at the site of previous strictureplasty.
Conservative resection is the norm. Even in involvement
of the colon, a physician should perform conservative
resection so that ideally the patient can be colostomy free
for many years. Margins of resection do not have to be
microscopically disease free, so long as macroscopically it
appears to be disease free. There have been several studies
debating the anastomosis technique.

The anastomosis can
be hand sewn or stapled. It can be side-to-side, end-to-side
or end-to-end. There is the same recurrence rate irrespective
of anastomosis technique. However, in a severely diseased
segment or if there is marked luminal discrepancy, a hand
sewn anastomosis ensures a smaller chance of complication.
When meticulously performed, a strictureplasty has the
same incidence of recurrence as that of resection.

One
must be aware that an albumin level below 2.0 can result in
infectious complications and non-healing. The stricture site
should not have active infection at the site of obstruction.
In such cases it would be best to divert the flow via a stoma.
There have been reports of cancer developing at the site of
stricture. Therefore, in suspicious areas, a biopsy should
be performed. If there is even dysplasia, a resection must
be carried out. Strictureplasty should not be attempted in
the presence of infection, perforation, abscess, presence of
phlegmon, dysplasia, any internal or external fistula and
severe hypoalbuminemia, such as less than 2.0 g/dL.

A
short segment of intestine with single or multiple strictures
and colonic strictures is best treated with resection. In rare
cases a duodenal stricture will present as high grade upper GI
