  Abstract 


Appetite for substances that are widely non-nutritive is termed Pica and commonly seen in patients with psychiatric disorders. Their clinical presentation may be delayed and include multiple foreign bodies. Most of such ingested bodies pass through gastrointestinal tract uneventfully and only on rare instances cause obstruction or perforation. The length and sharpness of an object govern its risk of perforation. Physicians are dependent upon imaging to detect a foreign body, especially if the history of ingestion is doubtful. We present a case of pica with multiple foreign bodies diagnosed on radiography and ultrasonography with the findings correlating with surgical retrieval of objects.

  Introduction Top


The pediatrics, emergency surgery, and gastroenterology units frequently have cases of foreign body ingestion. Psychiatric patients can swallow a wide variety of indigestible objects. Physicians must be familiar with signs and symptoms of the ingested foreign body, especially in these patients wherein no history of such episodes of ingestion is available.


  Case Report Top


We present a case of a 24-year-old man with a history of psychiatric illness who was on antidepressant medications for the past 1 year. On a previous outpatient visit, the patient's attendant gave an account of abdominal distension and altered bowel habits. The patient was uncommunicative; however, vitals were stable as were laboratory tests, excluding any drug-related side effects. Erect abdomen radiograph showed multiple metallic foreign bodies with dilated small bowel loops [Figure 1]. There was no radiological evidence of peritonitis, pneumoperitoneum, or intestinal obstruction. The patient showed stable vitals and was under observation, but left against the medical advice. After 15 days, the patient represented with a complaint of pain. Repeat erect abdomen radiograph showed an increase in number with a change in position of multiple metallic foreign bodies clumped in the right side of the abdomen that correlated with the visible lump in the right iliac fossa [circled in [Figure 2]. The ultrasonographic (USG) evaluation of the right iliac fossa confirmed the presence of echogenic elongated relatively well-defined intrabowel foreign body with associated reverberation artifacts [Figure 3]. The foreign body is seen perforating the bowel wall, with a small collection localized around it, suggesting sealed perforation. There was no ascites. A well-defined linear foreign body is seen penetrating the right lateral wall of the urinary bladder, with its sharp leading end being inside the bladder lumen and the blunt end in the perivesical region with a small associated focal collection [Figure 4]. Blood investigations show borderline normocytic anemia, mild thrombocytopenia (126,000 cells/mm3), borderline hyperkalemia (5.9 mEq/L), and mildly raised serum creatinine (1.3 mg/dL). His stool tested positive for the hemoccult fecal occult blood test. The patient underwent surgical explorative laparotomy, and multiple foreign bodies were recovered [Figure 5] with radiograph and ultrasound findings correlating well with operative findings.

  Discussion Top


Pica is a recurrent consumption of nonnutritive, nonfood items. To be called pica, these behaviors must last at least for a month. If consumption is developmentally or culturally appropriate (for example, it is a common practice in Africa to eat white clay), it is not pica.[1]

Pica shows an association with nutritional deficiency (iron, calcium), pregnancy, and psychological factors (such as poverty, maternal neglect, child abuse, lack of parental supervision, or a chaotic family situation).[2] Autism, mental retardation, depression or anxiety disorder, paranoid schizophrenia, impulse control disorder, substance abuse disorder, posttraumatic stress disorder,[3] and antipsychotics (such as olanzapine and risperidone) can also induce pica.[2],[4] Studies have shown worsening of pica by neuroleptic drugs and improvement by prescription of dopamine agonist (methylphenidate)/partial agonist (aripiprazole).[5],[6]

Pica needs to be ruled out in a psychiatric patient with bowel obstruction of an unknown cause, particularly in mentally retarded patients to prevent potential death or otherwise severe chronic consequences.[2],[7] These patients are more likely to ingest multiple objects and can be repeat offenders, as seen in our case. One study showed 11% mortality rate in 35 pica patients with 56 total ingestions. In 75% of these cases, surgical intervention was unavoidable.[7] Therapeutic approach should aim at early recognition and multidisciplinary management of the psychological stressors or triggers potentially responsible for pica.[2]

Ingested foreign bodies that pass into the stomach will traverse the rest of the gut uneventfully in >80% of cases.[8] Common location for ingested foreign body impaction is cricopharynx, midesophagus, lower esophageal sphincter, pylorus, ileocecal valves of Houston, and the anal sphincter.[9] Objects longer than 6 cm in length are difficult to pass through the C-loop of the proximal duodenum, and objects as small as 2 cm in length may get stuck in the pylorus.[10],[11] Objects that are pointed or have sharp ends may stick or pierce the mucosa and have a relatively slow transit time compared to rounded blunt objects which are expected to have a relatively shorter transit in the gastrointestinal tract (GIT).[12] The risk of perforation from an ingested sharp object depends on upon its size and orientation, and its significance lies in early detection and treatment.[13]

Although perforation can occur anywhere in the GIT, distal ileum is the most common site of perforation followed by ileocecal junction, left colon, and at the rectosigmoid junction due to their angulations.[14],[15]

Bowel perforations caused by the foreign body may present with abdominal pain (95%), fever (81%), or peritonitis (39%), mimicking acute intestinal conditions such as acute appendicitis, acute diverticulitis, and perforated peptic ulcer.[3]

If objects fail to pass through the gut in 3–4 weeks, the foreign body may adhere to the mucosa secondary to reactive fibrinous exudates, with a possible migration of objects extraluminally to unusual locations. After a foreign body has perforated a hollow viscus, it could lie inter/extra-luminal near the perforation site or adjacent/distant organs to perforate again or could pass out without complication.[8]

Physicians are dependent upon imaging to detect foreign objects, more so in cases where the history of ingestion is doubtful.

The first investigation usually is a radiograph to localize the site of the ingested foreign body. Radiograph has been found useful in a large number of cases as accidentally most swallowed foreign bodies are radiopaque and well appreciable.[12]

Plain radiographs fail to detect radiolucent foreign bodies such as plastic, certain types of glass, fish bones, and thin metallic objects, in which X-ray beam alignment is not in a proper direction. It offers limited data regarding the sharpness of an object.

Ultrasound can be helpful to evaluate the radiolucent foreign body-related symptoms associated with ingestion such as local peritonitis and perforation. In our case, detection of focal perforation of the urinary bladder by ultrasound in an asymptomatic patient guided the surgeon to take appropriate measure perioperatively. However, if urinary bladder perforation by a foreign body is suspected, cystoscopy may be of benefit to determine the extent of the invasion.

If pica is secondary to treatable internal diseases, treatment of the underlying disease is necessary. Cooperation between specialists (psychiatrists, general practitioners, surgeons, and gastroenterologists) is essential as there may be somatic consequences that require urgent care.[1] In primary cases of pica, psychotherapy is fundamental. Studies show that pica behavior can be decreased substantially with behavioral treatment (positive and negative reinforcements) and counseling.[1],[16] Taking into consideration that eating is repetitive, egodystonic, intrusive, it is postulated that pica lies in the obsessive–compulsive spectrum and hence responds to selective serotonin reuptake inhibitors (fluoxetine and sertraline).[1],[16] In case of pica secondary to nutritional deficiency, supplementation of vitamin and mineral affects the potency of behavioral intervention in patients with intellectual disability.[17]

In schizophrenic patients, pica presents as a rare, independent, and discrete behavior, but it is frequently missed in the diagnosis, and as a result, complications such as intestinal obstruction, electrolyte disturbances, and heavy metal poisoning may occur.[18]

The caregivers of mentally impaired patients should carefully watch out for foreign bodies ingestion, particularly in those with a prior history of pica and ingestion of multiple objects. Surgical removal is essential for the swallowed objects that are too large, numerous, or dangerous for endoscopic retrieval.[7]

Postoperative adhesions are well known in these patients following abdominal surgeries and pose a challenge to surgeons if the patient undergoes another surgery. For the prevention of future episodes, diligent efforts are required, including psychiatric counseling or psychotropic drugs if necessary, with regular follow-up.

Comorbidities significantly potentiate the problem of people with an intellectual impairment. Therefore, an accurate psychological assessment of multiple diagnoses is useful in detecting the specific underlying processes and in planning an appropriate management and rehabilitation program.[19]


  Conclusion Top


In unsuspected cases, foreign body perforation is difficult to diagnose without an aid of imaging modalities. Imaging is also helpful in situations where history cannot be taken appropriately as in children and psychiatric patients. A high index of clinical suspicion is needed as many foreign bodies are not radiopaque and cannot be picked up in radiographic investigations. Further imaging with ultrasound is helpful, which is readily available and quick to perform in an emergency room. Ultrasound is not only useful for detecting nonradiopaque foreign bodies but also for assessing associated localized, changes which can ensure an uneventful treatment and postoperative period. In metallic and multiple abutting foreign bodies, USG is more useful than computed tomography (CT) because CT-associated dense streak artifacts obscure the anatomical details.
