ABSTRACT
Metal bezoars are uncommon foreign bodies (FB)
in the gastrointestinal tract (GIT) and comprised of a wide variety of objects.
A 17-year-old schizophrenic presented with abdominal pain and distension along
with non-bilious vomiting for 2 weeks. Physical examination revealed dullness to
percussion in the epigastrium. Plain radiographs revealed objects of metal
density contained within a dilated stomach. Laparotomy was performed revealing
metal objects in stomach.

INTRODUCTION
A bezoar is a conglomeration
of partially digested or un-digestible foreign material in the gastrointestinal
tract (GIT) especially the stomach [1]. Bezoars occurring in the small
intestine, colon and rectum are less common [2]. Bezoars may produce a wide
variety of signs and symptoms depending upon their location, nature, volume and
duration. The clinical features may range from mild pain abdomen to intestinal
obstruction, perforation and peritonitis. Metal bezoars are rarely encountered
in surgical practice. Only few cases have been reported in literature [3,4]. We
are reporting a case of metal bezoars in a psychiatric
patient.
CASE REPORT
A 17-year-old boy presented to the accident and emergency room
with mild diffuse abdominal pain and abdominal distension for two weeks,
accompanied with vomiting of gastric contents along with metal fragments. The
patient was under treatment for schizophrenia but not taking medications
regularly. Physical examination revealed an afebrile patient with tachycardia
and tachypnea. The abdomen was soft but distended. A mass was palpable in the
epigastrium being dull to percussion. Plain radiograph of the abdomen showed
multiple objects of metal density contained within the stomach (Fig.
1).
The patient was admitted and upper GI endoscopy was attempted to
remove the FB but failed due to enormous size of bezoar. Open removal of the
bezoar was then planned. At operation, a grossly dilated stomach found. Through
a longitudinal gastrotomy multiple metal objects including: nails, copper wires,
blade, screws, rubber bands, coins and the remains of partially digested food
(measuring about half kilograms) were removed. The stomach was repaired in a
double layer fashion. Rest of the GIT was normal. Postoperative recovery was
uneventful. The patient was discharged and transferred to a psychiatric facility
7 days after surgery.
DISCUSSION
GI bezoars account for 4% of all
admissions for GIT obstruction. Approximately 10% of patients have associated
psychiatric abnormalities or mental retardation therefore psychiatric evaluation
and therapy are needed to prevent a recurrence. Metal bezoars are extremely rare
[4-7].
Metal bezoars can be easily diagnosed on abdominal radiographs as
in the index case; however diagnostic difficulties arise in patients with
radiolucent bezoars. GIT contrast studies and computed tomography (CT) scan are
necessary in such circumstances. Upper GI endoscopy is the method of choice in
detecting and dealing with esophageal, gastric and duodenal foreign bodies.
Occasionally, bezoars are found incidentally when an emergency laparotomy is
done secondarily to bowel obstruction [8-10].
Several treatment options
can be availed for the management of gastric metal bezoars. Endoscopic retrieval
is superior for small objects whereas in large objects open approach is
suitable. Once the obstruction occurs, surgery is the only way to solve the
problem. Frequently, synchronous bezoars are found in the stomach or other areas
of the gastrointestinal tract; therefore it is mandatory to carry out a thorough
exploration of the small intestine and colon to avoid future occurrence of
intestinal obstruction due to a retained bezoar [8]. The recurrence has been
reported in up to 14% of cases, especially in patients with psychiatric ailments
[3].
