Duodenal Web with Trichobezoar: An Unusual Presentation
obstruction. Usually the trichobezoar occurs in the stomach, and it may extend into the intestine as a tail causing Rapunzel syndrome [3]. The trichobezoar occurs more commonly in persons with psychiatric diseases with trichotillomania. Although no behavior of eating hair was noted by parents, the same may be present/ have happened accidentally due to intellectual deficit or inadequate supervision by parents. The cherry seeds reported in history may have precipitated the obstruction either by themselves or by acting as a nidus for the trichobezoar. Trichobezoar is usually diagnosed on ultrasound or CT scan of abdomen, and managed by retrieval through laparotomy or laparoscopy [4].
Duodenal atresia and duodenal web cause upper gastrointestinal obstruction and usually present in neonatal age soon after birth [1]. However, delayed presentation has been documented in literature in first few months or years of life related to partial obstruction. [2]. Here we report duodenal web presenting in the third year of life associated with trichobezoar in the duodenum.
A similar case has been reported in the French literature [5]. The association of duodenal atresia and Down syndrome helped us in suspecting the duodenal atresia. Although phytobezoars have been reported in early life, the incidence of trichobezoar in third year of life is rare. For a child with Down syndrome and recurrent vomiting, the differential for duodenal atresia should be high on the list and needs to be evaluated and managed promptly.
A 2-year-old girl with Down syndrome presented with complaints of recurrent vomiting of 2-3 months. The vomiting was non-bilious in nature and it contained ‘cherry seeds’ eaten about 3-4 months before. The child had no history of abdominal distension, blood in vomitus or bowel complaints. The child was well hydrated, afebrile, and with no previous complaints. Abdominal examination showed non-distended abdomen. No definite lump or tenderness was palpable. There was no free fluid and bowel sounds were normal. X-ray of abdomen revealed ‘double bubble’ with paucity of distal gas. A contrast study was done using water-soluble contrast agent, which showed hugely distended stomach with delayed drainage and normal small bowel. She was explored through supra-umbilical transverse incision. A hugely dilated stomach was identified. The second part of duodenum had a windsock deformity. Duodenotomy revealed a pre-ampullary web with trichobezoar obstructing the lumen. The gastric outlet was normal. The child was managed by duodenoduodenostomy. She remained well in post-operative period and is well on follow-up after 3 months.
