ABSTRACT
Small bowel
obstruction is a common surgical emergency but trichobezoar as an etiology,
rarely reported. A seven year old school going female child presented with acute
intestinal obstruction with a palpable and mobile mass in the abdomen. At
exploration, a 10 cm long trichobezoar was found in the distal ileum which was
removed through enterotomy. Postoperative course remained uneventful.
Further probing revealed that child used to eat her own scalp hairs at the age
of 2 years and the habit persisted for about 18 months which resulted in
alopecia at that time. Later on she started showing normal behavior.

INTRODUCTION
Trichobezoar is a ball of swallowed
hairs usually found in stomach. It is not an uncommon condition. It usually is
limited to stomach or may have its extension into small bowel in a form of tail
- the Rapunzel syndrome. Presence of trichobezoar in small bowel without a trace
in stomach is a rare occurrence [1,2]. Delayed presentation after many years of
presence of trichobezoar in alimentary tract is a rare event. We are reporting a
case of delayed presentation of trichobezoar which presented with acute small
bowel obstruction.
CASE REPORT
A seven-year-old female
child presented with acute onset of colicky abdominal pain and non bilious
vomiting for the preceding three days. There was no history of fever and passage
of round worms in stool. On examination the child was alert and of normal built.
Abdomen was not distended. It was soft with a palpable elongated mobile
minimally tender mass. A provisional diagnosis of mesenteric / ovarian cyst was
made.
X-ray abdomen was suggestive of mechanical obstruction. Ultrasound
showed mass to be non cystic. Abdominal lymph nodes were not enlarged and other
viscera were reported as normal.
At laparotomy an intraluminal mass was
found in distal ileum. It was compressible. Rest of bowel and stomach were
normal. An enterotomy was made and a large trichobezoar was removed. It was 10
cm long (Fig. 1). The enterotomy was then closed.
The
postoperative course remained uneventful. Further probing revealed that child
had habit of eating her own hairs from the age of 2 years which persisted for
about 18 months. Alopecia was reported at that age. Presently she is a normal
looking average built school child interested in surroundings and quite social;
but parents were concerned about her jealous behavior as to her younger sister.
Child was also consulted with a psychiatrist who following a session declared
that at present she has no ailment and being jealous of younger sibling is a
normal phenomenon.
DISCUSSION
Trichobezoar is a unique rare condition predominantly of
childhood and adolescence. It is a black, glistening, foul smelling mass, made
up of hairs present in the alimentary tract, commonly in stomach. There is
usually a preceding history trichotillomania (pulling own hairs) followed by
trichophagia (ingestion of hairs).
Not all the cases of trichotillomania have trichophagia nor all the
trichophagia develop trichobezoar. Although the exact cause of trichotillomania
is not clear certain psychosocial, behavioral, and biological theories have been
proposed like childhood trauma, stress and neurochemical imbalances (like of
serotonin) [3,4].
Hairs are non absorbable or digestible and also due to
smooth slippery texture not easily pass out of the alimentary tract. They remain
stuck in the folds of alimentary tract and usually jumbled up in stomach.
This bunch of hair can have extension in to distal bowel as a result of
peristaltic propulsion. It may get detached as satellite in distal intestine
with main part in the stomach. There are recurrent episodes of non specific pain
in abdomen, loss of appetite, vomiting and weight loss. Alopecia is the most
significant associated symptom in patients with this condition [5-8].
The patient in this report had onset of trichotillomania at a very early
age (2 years) which has been reported, though rarely. Contrary to the usual
cases, where these children have behavioral disturbances and failure to thrive,
our patient showed normal physical and mental health. She started pulling and
eating her hairs at the age of two years and left after 18months without any
specific reason or change of environment, which shows that it is not always the
underlying behavioral or psychological disturbance that leads to this habit.
This could be “short term habit of hair pulling” which is quite different from
trichotillomania. Jealously with the other siblings is a normal phenomenon (as
the psychiatrist pointed out in our case) [9].
Isolated
intestinal trichobezoars are rare but do occur and can have delayed
presentation, even after many years of leaving trichophagia. In the index case
the trichobezoar might remained in the stomach for years and then dislodged from
stomach and stuck in the small bowel, therefore, presented with the acute
intestinal obstruction. It is also an interesting fact that in the stomach the
trichobezoars do not produce any kind of symptoms for years.
To conclude,
delayed presentation of trichobezoar is a rare event. Ileal trichobezoar should
be placed in differential of mobile abdominal masses in young
girls.
