Gastric Bezoars

Bezoar is the accumulation and mass formation of indigestible materials inside the gastrointestinal tract on account of several factors. Bezoars are relatively infrequent, with a reported incidence of 0.07% to 0.4% [1]. Bezoars are classified into several types according to their composition: plant and vegetable fibres (phytobezoars), hair (trichobezoars), medications (pharmacobezoars), or milk protein in milk-fed infants (lactobezoars). Elderly patients and those with diabetes mellitus or a history of gastrointestinal surgery are more likely to develop bezoars due to impaired gastric motility and delayed gastric emptying. Additionally, mental retardation and trichotillomania also are known as risk factors for the development of trichobezoars. Bezoars are mostly seen in stomach, oesophagus, small bowel, large bowel, and bile duct. It can be presented with anaemia, haematemesis, nausea, vomiting, and weight loss. Iron deficiency anaemia, which is widely common in patients with trichobezoar, is mostly a direct outcome of some gastric ulcers caused by the pressure effect of mass. Bezoars can cause gastrointestinal complications like bleeding, gastric outlet obstruction, and ileus [2]. In this case we present an endoscopic removal of bezoar from a mentally retarded female patient.
A mentally retarded 51-year-old female patient was admitted to our hospital for symptoms of epigastric pain, nausea, vomiting, and weight loss (10 kg in the preceding year) over the course of the previous 3 years and aggravated in the previous month. She had a hair- and nail-eating habitat. In her blood samples, haemoglobin was 7.8 g/dl and mean corpuscular volume (MCV) was 61.2 fl. Two hard black/yellowish coloured bezoars were revealed in her upper gastrointestinal endoscopy (Figure 1 A–B). Bezoars were fractionated by polypectomy snare catheter and extracted in two sessions. There were two ulcers of size 3–4 mm in diameter seen after complete removal of the bezoars (Figure 2). The patient’s symptoms were relieved after this endoscopic intervention.
The aim of the treatment was complete extraction of the bezoar. There are different alternative treatment methods such as liquid diet, prokinetic agents, dissolution of bezoar, and endoscopic or surgical extraction. Coca-Cola may be administered orally or via endoscopy for dissolution of phytobezoars; however, it is not effective on its own and must be given together with a prokinetic agent like metoclopramide [3].
