Alimentary tract duplications are unusual anomalies that may require surgical intervention in the neonate, infant, and occasionally in the older child. The clinical presentation of patients with alimentary tract duplications includes bleeding, abdominal pain, intussusception, and respiratory distress, or it may be an incidental finding on either abdominal examination or chest x-ray. A review of 96 patients with 101 duplications seen over the last 37 years is reported herein. Twenty-one duplications were confined to the thorax; three were thoracoabdominal, and 77 were abdominal. Seventy-four patients presented as infants less than 2 years of age, and 22 patients were older. Ectopic gastric mucosa was found in 21 duplications, and pancreatic tissue was found in five. Seventy-five duplications were cystic and 26 were tubular. Ultrasonography, computed tomography (CT), and myelography are helpful diagnostic tools. Ninety-four of the 96 patients underwent surgical management for their duplications. One duplication was found at necropsy, and one patient was asymptomatic and did not undergo operation. A single death occurred in a 2-day-old infant who had intrauterine volvulus and meconium peritonitis. Management was based on the age and condition of the patient, the location of the lesion, whether it was cystic or tubular and communicating with the true intestinal lumen, and whether it involved one or more anatomic locations. Generally, total excision was preferred, but staged approaches were sometimes necessary.

Duplications of the alimentary tract are unusual congenital anomalies that frequently present a diagnostic as well as therapeutic challenge to the surgeon. Because these lesions occur so infrequently, they are often not suspected until encountered intraoperatively. Due to the complicated anatomy and common blood supply shared between the duplication and associated native bowel, appropriate management requires a familiarity with the anatomy and clinical characteristics of this entity. To better define the range of patient characteristics, clinical presentation, and preferred therapy, 20 enteric duplications were reviewed in 17 patients treated at the Children's Hospital Medical Center from 1956 to 1986. Ages of patients ranged from 1 day to 11 years; 60% were less than 2 years of age at initial presentation. Seven duplications in six patients involved alimentary tract structures of foregut derivation (esophagus, stomach, and Parts I and II of duodenum), with a predominance of girls (4 of 6). Most of these patients (67%) presented with moderate to severe acute respiratory distress and a mass present on chest radiograph. In 67% of the patients, the correct diagnosis was established before operation. None required emergency operative intervention. By contrast, 13 duplications in 11 patients were of midgut or hindgut derivation (Parts III and IV of the duodenum, jejunum, ileum, and colon). In this group of patients, 62% of the duplications involved the cecum, 23% involved the ileum, and 16%, the jejunum. Seventy-eight per cent of the patients were boys. The most common symptoms were nausea and vomiting, and the most common sign was a palpable abdominal mass. Emergency operative intervention was required of eight of 11 patients with duplications involving the small bowel and colon. Three patients presented with an intussusception, four with signs and symptoms consistent with acute appendicitis, one with a small bowel obstruction, and two with gastrointestinal hemorrhage due to the presence of ectopic gastric mucosa within the duplication. It was found that two important points must be considered in regard to the management of enteric duplications: (1) the common blood supply shared between the duplication and native bowel must be carefully protected to avoid undue sacrifice of normal bowel, and (2) the presence of heterotopic gastric mucosa in 35% of patients negates internal drainage.(ABSTRACT TRUNCATED AT 400 WORDS)

Two premature infants with abdominal distension, respiratory distress syndrome, and sepsis were initially diagnosed and treated for necrotizing enterocolitis (NEC). After failure of conservative measures, a diagnosis of intussusception was contemplated. This pitfall in the management of NEC, with medical treatment and a poor response, has been increasingly reported.

A progressive pulmonary disease resulting in severe respiratory failure and death in an average of 3 weeks was diagnosed in 11 young Dalmatian dogs. The dogs were from 4 litters, all genetically related by a common ancestor. The initial clinical signs were tachypnea and noisy respiration. Respiratory distress developed shortly before death and was characterized by strenuous and rapid respirations, along with cyanosis and vomiting. On blood gas analysis, there were severe arterial hypoxemia, hypercapnia, and marked alveolar-arterial oxygen difference. Radiographically, a diffuse pattern of alveolar, interstitial, and peribronchial densities was observed in the lungs. Most dogs developed pneumomediastinum and gastroesophageal intussusception in the terminal phase of the disease. There was no response to treatment with antibiotics, corticosteroids, diuretics, or oxygen. At necropsy, the lungs were wet, heavy, and relatively airless. Absence of 1 kidney in 2 dogs and severe internal hydrocephalus in 2 dogs were additional necropsy findings. Pulmonary histopathology included metaplasia and atypia of the alveolar and bronchiolar epithelium, a nonpurulent inflammatory reaction characterized mainly by mononuclear cells and macrophages, eosinophilic hyaline membrane formation, and focal pulmonary fibrosis. The histological manifestations were typical of acute lung injury. Clinically, the findings were consistent with adult respiratory distress syndrome (ARDS), except for the relatively long course. No known risk factors for ARDS, such as trauma, toxin exposure, infection, or endotoxemia could be identified. The relationship of the other abnormalities (ie, renal aplasia, hydrocephalus) to the pulmonary disease also remains obscure. An inherited defect is suspected, because segregation analysis of the 4 litters suggests autosomal recessive inheritance.

Perforation during attempted gas-enema reduction of intussusception is more common than during a barium enema. In a review of 650 consecutive attempted gas enemas, perforation occurred in 7 infants (1.1%). Gross abdominal distension from the pneumoperitoneum may be rapid and cause splinting of the diaphragm, which leads to acute respiratory distress. This complication is readily recognised at the time of the gas enema, and may require immediate intervention by paracentesis using a 14-gauge needle. A review of 7 children with intussusception in whom perforation occurred revealed that all had radiologic evidence of bowel obstruction (air-fluid levels) prior to the enema, and the patients had had a relatively long history since the onset of symptoms. No perforation occurred during a delayed repeat enema reduction. Perforation during gas enema produces minimal peritoneal contamination. No pathological lesion at the lead point of the intussusception was identified in any of the children in whom perforation occurred.

Gastric volvulus (GV) is a rare condition in infants. The aim of this study was to define the management strategies of infants with GV based on their clinical and radiologic features. The medical records of 13 infants with a radiologically confirmed diagnosis of GV were retrospectively reviewed. Patients were divided into two groups according to the type of treatment (surgical vs conservative). Abdominal radiographs and upper gastrointestinal contrast studies allowed an unequivocal diagnosis in both groups. Group 1 included 3 infants with acute GV and 2 with chronic, intermittent secondary GV. Three patients had associated diaphragmatic defects, 1 had an ileocolic intussusception, and 1 had hypertrophic pyloric stenosis. The main presenting symptoms were vomiting, dehydration, respiratory distress, and abdominal pain and distention in acute cases and vomiting and failure to thrive in chronic cases. A laparotomy was required in all 5 infants with no recurrence of symptoms. Group 2 included 8 infants with idiopathic chronic GV, who were managed nonoperatively with gradual improvement of symptoms over 12 months. Based on our study, we conclude that: (1) laparotomy can be reserved for patients with either acute or chronic secondary GV; (2) conservative treatment is both safe and effective in infants with chronic idiopathic GV; and (3) routine gastropexy for all patients with a radiologic diagnosis of GV appears to be overtreatment.

Ureteric intussusception is exceptional. The authors report a case of hydronephrosis due to retrograde intussusception of the subpelvic ureter in a 3-month-old boy admitted for respiratory distress syndrome associated with fever of 39 degrees C. Imaging revealed the presence of marked dilatation of the left kidney. Surgical exploration demonstrated hydronephrosis secondary to obstruction due to ureteric intussusception. This is the first case of ureteric intussusception reported in a child.

A 7-week-old, female Siberian husky was presented to Murdoch University Veterinary Hospital with an acute onset of respiratory distress and regurgitation. Thoracic imaging identified an intraluminal esophageal mass with concurrent aspiration pneumonia. Esophagoscopy identified the mass as stomach, and a diagnosis of gastroesophageal intussusception was made. The intussusception was reduced endoscopically, and fixation of the stomach to the abdominal wall was performed using a tube gastropexy. Gastroesophageal intussusception is an uncommon disease in small animals and traditionally has been managed surgically. This case report describes an alternative method of treatment associated with a good outcome in this puppy.
