Congenital aganglionic megacolon.

Twenty-one pull-through procedures for congenital aganglionic megacolon (Hirschsprung's disease) have been performed at the Los Angeles Children's Hospital since the adoption of the etiological concept of a distal aganglionic segment in 1949. In 14 cases the Swenson procedure as modified by Hiatt was employed, with perineal excision of the colon segment. There were four postoperative deaths and three symptomatic recurrences in this group. Three patients were treated by transabdominal resection of colon and rectum with subsequent pull-through reconstruction (Swenson). Anterior resection (State) was carried out in two cases. Three children with recurrence of symptoms following primary operation were subjected to a secondary pull-through procedure with an eventual successful outcome. The major portion of the postoperative mortality (29 per cent) in this group occurred in infants less than six months of age in whom anastomotic disruption or proximal segment infarction occurred after operation.A study of 31 cases of congenital aganglionic megacolon in very young infants drew attention to the difficulty of establishing a diagnosis in this age group even at exploratory laparotomy. Among these infants the mortality rate was excessive, regardless of the form of therapy employed. Colostomy appeared to be the indicated surgical procedure if a conservative regimen failed to control intractable colonic obstruction during the first year of life.

Unusual abdominal cysts in infants and children.

In a 20-year period at the Los Angeles Children's Hospital, 46 infants and children have had operation for cysts within the abdomen. The age range of patients was from newborn to 13 years. Most of them were under four years old. There were four general groups of these cysts. (1) About one-half were cysts of the ovary, some of them serous and some dermoid. These cysts are attached by a stalk that often twists, causing gangrene or rupture with acute symptoms simulating appendicitis. (2) Next in frequency were cysts arising in the mesentery of the intestine. They usually caused little trouble until by their size (up to a 2-quart capacity) they created pressure and obstruction in the intestine. (3) Enteric cysts were found in four patients. (4) Cysts of the pancreas were present in three of the children.X-ray examination was helpful in diagnosis. Usually the type of cyst was not determined until operation was done. Transection of the intestinal tract sometimes was necessary for removal of the cyst. Surgical correction was satisfactory in 44 of the 46 cases.
