Heterotopic Gastric and Esophageal Tissue in the Colon

Laparoscopic-assisted sigmoid resection for colonic ectasia in a neonate

“…The benefits of laparoscopic approach in infants have been demonstrated in several reports [11,12]. In neonates, avoidance of hypothermia is an added important advantage.…”

Segmental dilatation of sigmoid colon in a neonate: atypical presentation and histology

“…Ratcliffe et al [6] reviewed 36 cases of segmental dilatation involving various parts of the bowel in 1989. Although these have been reported from birth to 22 years of age [1] and occur in either the small bowel or colon, only 9 cases have been described involving the colon in neonates [3,[6][7][8][9][10][11][12][13][14][15], 4 of these with anorectal malformations [9,10,[12][13][14].…”

“…Microscopically, hypertrophy of the circular and longitudinal layers of the muscularis propria in the dilated segment is evident in older infants/children and is probably an acquired functional adaptation secondary to chronic fecal distention [3,20]. In the neonates, the muscularis propria has been earlier observed to be normal or occasionally sparse [3,[6][7][8][9][10][11][12][13][14][15]. The hypertrophy of both layers of the muscularis propria in this case is akin to that noted in older infants/children.…”

Idiopathic localized dilatation of the ileum in adults

“…Since 1959 additional reports have d o c u m e n t e d similar lesions in the j e j u n u m [2,3], ileum [4][5][6], and colon [7][8][9]. Various forms of heteroplasia have also been f o u n d within the dilated segments, including pulm o n a r y , laryngeal, and esophageal tissues [6,9].…”

“…Various forms of heteroplasia have also been f o u n d within the dilated segments, including pulm o n a r y , laryngeal, and esophageal tissues [6,9]. A case reported by A t e r m a n and Abaci [8] showed heterotopic gastric m u c o s a without ulceration. In our first patient the resected specimen contained dysplastic mucosa and an ulcer; the latter finding has not previously been associated with this entity (Fig.…”
