Brown bowel syndrome: a late complication of intestinal atresia.

Two children, aged 11 years, who originally had jejunal atresia corrected in the neonatal period, developed massive dilatation of the proximal small intestine. This resulted in circular muscular hypertrophy with lipofuscin deposits giving the typical appearance of "brown bowel." The condition was associated with malnutrition and vitamin E deficiency. Because of relatively short bowel, the condition was treated by limited resection and extensive tapering of the dilated segment, end-to-end reanastomosis, vitamin E supplementation, and intensive nutritional support.

[Intestinal atresia and bile duct atresia in a new born infant].

We report a recent case of small bowel atresia and biliary atresia in a newborn. We describe the management of the patient and we make a revision of the literature. Only 13 cases have been found, that confirms that this association is extraordinary rare.

Does small intestinal atresia affect epithelial protein expression in human newborns?

OBJECTIVES: Bowel segments distal to a congenital intestinal obstruction have been suggested to be immature. In other words, luminal components such as amniotic fluid (before birth) and/or enteral nutrition (after birth) may be required to activate intestinal epithelial protein expression, thereby influencing epithelial differentiation. We investigated cell-type-specific protein expression proximal and distal to jejunal and ileal atresias in human newborns. PATIENTS AND METHODS: We immunohistochemically studied intestinal tissue specimens of 16 newborns who had undergone surgery for jejunal or ileal atresia. Sections were taken from both the proximal and distal sides of the atresias. RESULTS: For all patients, the enterocyte-specific markers lactase, sucrase-isomaltase, sodium glucose cotransporter 1, glucose transporters 2 and 5, intestinal fatty acid-binding protein and alkaline phosphatase were expressed at a mean 3 +/- 1 days after birth, both proximal and distal to jejunal and ileal atresias. Expression of goblet cell-specific markers mucin 2 and trefoil factor 3 and that of the Paneth cell marker lysozyme was maintained at either side of the atretic segment. CONCLUSIONS: With respect to the markers used, the human small intestinal epithelium is already differentiated shortly after birth. The absence of intestinal continuity in case of a jejunal or ileal atresia does not affect epithelial protein expression. This would seem to indicate that the developing small intestinal epithelium matures independently of luminal components.

Intestinal atresia with segmental musculature and neural defect.

BACKGROUND/PURPOSE: The aim of this study was to investigate the possible etiologic factors of small bowel atresia and to detect the prognostic role of adequate resection and tapering in postoperative morbidity and mortality. METHODS: Intestinal resection specimens were obtained from 10 patients with jejunoileal atresia and 3 control subjects without any gastrointestinal disease. Intestinal specimens taken from 2-cm and 4-cm proximal sides of atresia, atretic segment, and 1-cm and 2-cm distal sides of atresia were stained with Masson trichrome and H&E. Immunohistochemical staining of the biopsy specimens with synaptophysin was also performed to ascertain the number, the intensity, and the morphology of ganglia. RESULTS: At the blind proximal end, there was segmental absence of muscular layers, presence of neural defects, and replacement of the muscular layers with fibrous tissue beside the relatively intact mucosa. CONCLUSIONS: Segmental defects in muscular and neural structures of the intestinal wall observed in both the antimesenteric and mesenteric sides of the atretic small bowel were considered to support the vascular insult theory as an etiologic factor. Adequate resection rather than tapering the dilated proximal atretic intestinal segment should be included in the surgical treatment of this pathology to avoid the intestinal dysmotility, which may result in gut-related sepsis and death in the postoperative period.
