title: A clinical study of young infants after small intestinal resection.
abstract: We prospectively studied 15 infants who, before 3 months of age, underwent resection of the small intestine-proximal in 3 infants, mid in 6, and distal in 6. Two died before one year of age. Many required prolonged parenteral nutrition, but by one year, 12 of the 13 survivors were on oral feedings only, and seven were above the third percentile for height and weight. Developmental delay occurred in the early postoperative period but diminished with time. There was compensatory adaptation of the remaining gut, shown by improving fat and B12 absorption and duodenal bile-salt concentrations. Bacterial contamination complicating end-to-side anastomoses occurred in two cases (P), gastric hyperacidity in four of 12 (1P, 3M), and hyperoxaluria in eight of 14 (1P, 5M, 2D). Studies of immune competence revealed normal cellular immune function (11/11), transient hypogammaglobulinemia (3/14), hypocomplementemia (1/12), and serum autoantibodies (3/10). Thus, massive resection of the small intestine did not preclude spontaneous improvement in absorptive function, growth, and development.
