Unusual cause of palpable mass in upper abdomen--giant gastric trichobezoar: report of a case

Large trichobezoar associated with misdiagnosis, a rare case report with a brief literature review

Introduction

Trichobezoar is a rare disorder that almost exclusively affects young females. Up to 90% between 13 and 20 years of age. The current study aims to report and discuss a rare case of Misdiagnosis of Trichobezoar.

Case presentation

A 14-year-old girl student patient admitted to the Baxshin hospital, with a large trichobezoar filling the entire stomach with a long tail of hair extending within the pylorus into the proximal jejunum at a length of 70 cm; associated with abdominal pain, constipation, and vomiting. Laboratory data showed mild iron deficiency anemia, with a normal liver, and renal function test, patients' electrolytes showed a normal profile. Confirmation of the presence of the mass was done through abdominal Computed Tomography (CT) with contrast. The physician initially diagnosed as alopecia and suspected the abdominal pain was related to the postprandial emesis because the patient didn't provide a history of trichotillomania and used treatment for alopecia for a long time.

Discussion

The presence of a mass in the abdomen of a child is considered one of the most severe findings. Physical examination of the patient plus a full history taken, and the age of the patients provide a clear clue to the origin of the mass. Further investigation, including laboratory data and imaging findings, provides better understanding and a firm diagnosis. Trichobezoar should be considered by the physicians in this case.

Conclusion

In the early diagnosis of the trichobezoar, the physicians should investigate for any medical history of clinical trichophagia, trichotillomania, or a psychological problem.

•

The initial step of trichobezoar diagnosis is a direct question about consuming hair.

•

Trichobezoar formation is caused by a delay in diagnosing trichotillomania and trichophagia.

•

Physicians should investigate for any medical history of trichophagia, trichotillomania, or a psychological problem.

•

The clinical feature of trichobezoar usually associated with alopecia of the scalp and other regions of the body

Gastric Bezoar: Retrieve it, Leave it, or Disbelieve it?

OBJECTIVES

To determine the demographics, potential risk factors, endoscopic interventions and outcomes relating to gastric bezoars in pediatric patients; and comparing results with previously published literature.

METHODS

Retrospective series by chart review of patients identified by International Classification of Diseases-9 codes 938 and 935, using the following Medical Subject Headings: 1, term bezoar; 2, Keywords gastric bezoar∗ or gastric foreign body∗.

RESULTS

Thirty pediatric patients between ages of 2 to 18 years were found with gastric bezoars, with a female predominance. Majority had a phytobezoar. Six patients were diagnosed with dysautonomia, implying possible role of autonomic dysfunction contributing to abnormal gastric retention. Frequent symptoms included abdominal pain, nausea and vomiting, a decrease in appetite, and unintentional weight loss. A higher prevalence of underlying gastrointestinal disorders was found in those with bezoars. Nuclear medicine gastric emptying scan performed in 13 children was significantly abnormal in only 4 of these children. Most patients were treated with endoscopic removal of the bezoar. Endoscopic removal was accomplished by Roth net, generally requiring multiple passes. At follow-up, most of the children had improvement of symptoms, with bezoar recurrence in 1 patient.

CONCLUSIONS

This is to our knowledge the largest series of gastric bezoars in pediatrics. On the basis of our review, phytobezoars may be under-reported in pediatrics. Bezoars should be considered in children presenting with chronic abdominal pain, nausea, and vomiting; even in developmentally normal children and those with normal gastric emptying. We suggest that dysautonomia and underlying gastrointestinal disorders may be potential risk factors.

Rapunzel syndrome: an infrequent cause of severe iron deficiency anemia and abdominal pain presenting to the pediatric emergency department

Background

Iron deficiency anemia (IDA) and abdominal pain are commonly seen in a pediatric emergency department (8 and 18% incidence respectively in our center). They are manifestations of a wide variety of diseases ranging from benign to immediately life-threatening. Trichobezoar is an under-diagnosed entity that has to be considered in children and adolescents, expecially female, suffering from trichotillomania (compulsion to pull hair) and trichophagy (compulsion to swallow hair). When undiagnosed, gastric bezoars may cause gastric ulceration, perforation, haemorrhage and obstruction.

Case presentation

To underline the importance of including this pathology in the differential diagnosis of IDA and abdominal pain, we present the case of a 14 year-old girl with a huge trichobezoar which completely filled the stomach and extended into the small bowel. Since trichobezoar has an extension to the small bowel, it is classified as Rapunzel syndrome. As the bezoar couldn’t be removed by endoscopy, the girl underwent surgical intervention. The patient passed through a gradual re-feeding, with iron and vitamins supplementation, and through a psychiatric counselling.

Conclusion

The Rapunzel syndrome is a rare entity that may be complicated by life-threatening events. A prompt diagnosis and an appropriate therapy can reduce comorbidities. Gradual re-feeding with supplementation of micronutrients allows adequate catch-up weight with normalization of haematochemical nutritional parameters. Since many of these patients suffer from psychiatric pathology such as PICA with emotional problems and mental retardation, psychological/psychiatric counselling plays an important role in order to prevent bezoar recurrence.

Unusual trichobezoar of the stomach and the intestine: a case report

INTRODUCTION

Trichobezoars are an infrequent form of bezoar found in the stomach or intestine, created from ingested hair. This condition has been well described in the surgical literature, but less reported in psychiatry.

CASE PRESENTATION

We describe the case of an 18-year-old Middle Eastern Caucasian woman with trichotillomania who presented to our emergency department with a history of central abdominal pain associated with vomiting and constipation for five days. An examination showed a trichobezoar requiring emergent surgical intervention, and indicating the need for psychiatric treatment. The trichobezoar was treated successfully by laparotomy.

CONCLUSION

The medical and psychiatric sequelae of trichotillomania should not be underestimated, and early diagnosis and treatment is of utmost importance to save the patient's life and prevent recurrence. Although laparotomy is still considered an excellent option, pharmacotherapy and behavioral assessment play a useful role in patient management. Our case highlights the fundamental concept of a holistic approach rather than only treating the symptoms, by considering factors such as genetic influences to understand the disease.

Complications of bezoar in children: what is new?

A bezoar is a mass found trapped in the gastrointestinal system. The condition may be associated with pica, especially in developmentally retarded children. Clinical manifestations are usually nonspecific. Endoscopic diagnosis and removal of the foreign materials is often indicated. Occasionally, severe complications may occur. We report two cases to illustrate the clinical features and complications in these children. In the first case, a reliable history was not obtained in the developmentally delayed girl which precluded prompt diagnosis, but the grossly dilated stomach on plain abdominal radiograph gave clues to an underlying insidious mechanical obstruction of upper gastrointestinal tract. In the second case of a normal child, the unrelenting symptoms and weight loss prompt further investigations which revealed the diagnosis. Literature on pediatric bezoar is reviewed. Oesophagoduodenoscopy is the investigation of choice for diagnostic confirmation, but surgical facilities must be available to deal with acute complications.
