Microcolon is a radiological finding of a colon of tiny caliber on barium enema examination. There are no absolute standards for measurement of this condition which is probably caused in utero by lack of appropriate distention of the colon with intramural content. A review was undertaken of 228 barium enema examinations of newborns admitted to Mackay Memorial hospital from January 1987 to December 1988. Twenty cases (8.7%) were regarded by the same radiologist as microcolon. Among them, ileal atresia was found in nine cases (45%); colonic atresia in two cases (10%); total colon agangliosis in three cases (15%); prenatal volvulus in two cases (10%); meconium ileus in two cases (10%); duplication of ileum in one case (5%): and megacystis-microcolon-intestinal hypoperistasis (MMIHS) in one case (5%). The characteristic features of plain abdomen and barium enema study were discussed. The finding of a microcolon on contrast enema study in newborn with lower gastrointestinal obstruction signifies that it may rise from lower gastrointestinal obstruction above colon, external compression, or motility disorder of the intestine itself. The outcome of microcolon seems to depend on its underlying causes. In those caused by obstruction, only the caliber may return to normal within days after removal of the obstruction.

Twenty cases of meconium peritonitis were found between September 1980 and March 1988 at Mackay Memorial Hospital. The male to female ratio was 1.5 to 1. Six of the 20 cases involved premature babies. The great majority presented symptoms and signs before 5 days old, but one case was not diagnosed until 13 months of age. Polyhydramnios of the mother was found in six cases (30%). Abdominal distension was the universal symptom in all 20 cases. Hydrocele was noticed in 8 of the 12 male babies. In seven cases (35%) radiological examination showed abdominal calcifications. All patients underwent surgical intervention. Peritonitis was of cystic type in seven cases (35%); fibroadhesive in nine cases (45%); generalized in four cases (20%). Evident intestinal perforation was noted in 13 patients, and a mechanical obstructive lesion was found in 9 cases (45%) including intestinal diaphragm, atresia, volvulus, and Hirschsprung's disease. In only two patients (10%) was neither evident perforation nor obstructive lesion. The overall mortality rate was 30% (6/20), with no mortality after 1986 (0/6). The mortality seemed increased in those associated with perforation (4/13) and midgut volvulus (2/2) in particular, compared with non-perforation cases (1/7). It appears that early aggressive operation, and meticulous postoperative care, have contributed to the higher survival rate in recent years.

Persistent omphalomesenteric band is a rare cause of volvulus or intestinal obstruction. A 7-month-old male infant was brought to this Emergency Room after having shown poor appetite for three days, frequent bilious vomiting, and fever for half a day. Physical examination revealed the infant was dehydrated and had slight abdominal distension as well as hypoactive bowel sounds with a tender, ill-defined mass over right lower quadrant. Radiography and sonography were consistent with distal small bowel obstruction. Emergent laparotomy was done and a fibrous band found extending from the anti-mesenteric border of the ileum to the posterior wall of the umbilicus. Small bowel volvulus had occurred around the band and dilated small bowel was noted. An understanding of the embryologic development of these structures and their normal disappearance may assist pediatricians and surgeons to make the correct diagnosis and select the right pathoanatomic approach in surgery.

Neonatal intussusception is an uncommon disease. We report a case of neonatal ileoileocolic intussusception led by an ileal polyp in a female neonate. The patient presented with irritable crying, bilious vomiting and frank bloody stool on the 26th day of life. On physical examination, a mobile abdominal mass was palpated. Abdominal sonography demonstrated a long segment intussusception; associated with a low echogenic mass. At laparotomy, ileoileocolic intussusception led by an ileal polyp was found. Pathology confirmed the diagnosis of polyp. Because intestinal obstruction is the primary manifestation, neonatal intussusception is initially indistinguishable from obstructions due to other reasons like intestinal atresia, congenital bands, necrotizing enterocolitis or midgut volvulus. Our experience showed that although uncommon, intussusception should be considered in the differential diagnosis of intestinal obstruction during the newborn period.
