“…In most reported cases of gastric heterotopia involving the jejunum (Table 1), patients had a median age of 21.5 years with the youngest patient being one-year-old [6]. Presenting symptoms consisted of gastrointestinal bleeding [7][8][9] or obstructive symptoms as a result of a polypoid mass [1,5,[10][11][12][13][14][15][16][17] and stricture [2,3,6]. One case report described a 16-year-old patient who developed perforation and ulceration involving the jejunum in the setting of gastric heterotopia [18].…”

Heterotopia is the presence of normal physiologic tissue in an atypical location. Gastric heterotopia has been described in various locations throughout the gastrointestinal tract, including the small intestine. Gastric heterotopia of the small intestine typically is asymptomatic but may present in several ways with symptoms of obstruction, bleeding, perforation, intussusception, or pain. However, gastric heterotopia is rare beyond the duodenum except for its frequent association with Meckel’s diverticulum. This entity should be considered in the differential diagnosis of polypoid lesions presenting with symptoms of bleeding or obstruction especially in younger patients. We present a case of gastric heterotopia of the jejunum in a patient with a prior history of Meckel’s diverticulectomy after he presented with obstructive symptoms. His symptoms improved following resection of two jejunal polyps via antegrade double-balloon assisted enteroscopy with fluoroscopy. On histopathlogical examination, findings were consistent with gastric heterotopia. This case highlights the importance of considering gastric heterotopia in the differential diagnosis of polypoid lesions located beyond the ligament of Treitz in younger patients presenting with obstructive symptoms.

“…Clinical presentation of HGM varies and depends on the location and size of the heterotopic tissue. The most common complication of HGM is intestinal mucosal ulceration with gastrointestinal bleeding [8, 9]. It can also form an intraluminal mass causing intestinal obstruction.…”

Intussusception is the leading cause for intestinal obstruction in children. However, it accounts for only 5% of bowel obstructions in adults. Heterotopic gastric mucosa (HGM) can occur anywhere in the gastrointestinal tract; nevertheless, its occurrence in the small intestine is rare unless associated with remnants of vitelline duct (Meckel’s diverticulum). Herein, we describe a case of a 33-year-old male who presented with symptoms and signs of intestinal obstruction caused by ileo-colic intussusception, in which polypoid HGM acted as the organic lead point for intussusception. Several cases of intussusception caused by HGM have been reported in pediatric age group; however, this event is exceedingly rare in adults.

“…However, once the lesion has been detected, appropriate treatment, which will reduce the risk of complications, can be implemented 2 . Clinical presentations of HGM, such as intestinal obstruction, bleeding, perforation, and fistula formation to adjacent structures, vary and depend on the location and size 3 . It has also been reported that solitary large HGMs may be difficult to differentiate from malignant neoplasms such as carcinomas 4 ; however, a differential diagnosis for it has yet to be established.…”
