Intestinal malrotation may be complicated by volvulus and intestinal necrosis. One hundred two children (64 male, 38 female) undergoing surgical abdominal exploration from 1977 to 1987 had malrotation. Fifty-two patients were less than 7 days of age, 13 from 8 to 30 days, 26 from 31 to 365 days, and 11 were older than 1 year of age. Of infants, 39 of 65 had 40-week gestations, 18 of 65 had 36- to 39-week gestations, and 8 of 65 had less than 36-week gestations. Chief symptomatology included: bilious emesis (47), intestinal obstruction (19), abdominal pain (11), and bloody stools (7). Seventy patients had congenital anomalies (50 single, 20 multiple). Diagnostic evaluations included 56 upper gastrointestinal series and 27 barium enemas. Each patient underwent correction of malrotation and appendectomy, and correction of congenital anomalies (omphalocele-9, gastroschisis-6, diaphragmatic hernia-7). Complications included short gut (2), sepsis (5), feeding difficulties (2), pneumonia (3), small bowel obstruction (2), and other (15). Nine patients (8.8%) died (trisomy 18-1, trisomy 13-1, intestinal necrosis-3, hepatic failure-1, prematurity-1, other sepsis-2). Two hundred sixteen children with intestinal malrotation have been treated from 1937 to 1987. Mortality rate has improved from 23% to 2.9%.
During a 21-year period, 39 colon interposition operations were performed on 37 children at the UCLA Medical Center and the Childrens Hospital of Los Angeles. The average age at the time of operation was 5.8 years. The indications for operation were esophageal atresia in 23 patients and other benign strictures in 14 patients. The duration of patient follow-up ranged from 6 months to 21 years (mean: 9.7 years). The most common complications were esophagocolonic anastomotic leak (12), esophagocolonic anastomotic stricture (14), pneumonia, and pneumothorax. Fourteen of the 25 patients with retrosternal colon interposition had complications (56%), whereas 10 of 14 patients with left thoracic colon interposition had complications (71%). One patient died (mortality: 3%) after left thoracic interposition because of severe respiratory distress associated with other malformations. Each of the 18 patients with isoperistaltic colon interposition showed rapid transit and emptying, provided that obstruction or extensive dilatation did not occur; reverse colon segments were more dilated and emptied more slowly. The 25 patients with retrosternal colon segments had less colonic distension with better emptying than did the 14 patients with left thoracic interposition. Thirty-two of the 36 children increased their weight percentile after colon interposition. Within 2 years after cervical anastomotic stricture or leak, 78% of these children were asymptomatic and gaining weight. Thirty-one of the 37 patients (84%) had excellent results with colon interposition, with a mean follow-up of 9.7 years. Most of the major postoperative complications occurred within the first few weeks and were corrected during the first few months after operation. Preservation of the esophagus should be the surgeon's first priority; however, prolonged attempts to elongate the esophagus for anastomosis in certain patients with long-gap esophageal atresia have been more hazardous in our experience than has colon interposition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
