The splenic snood: an improved approach for the management of the wandering spleen.

A wandering spleen is in constant danger of torsion and infarction. Splenectomy, the traditional treatment, leaves children in danger of postsplenectomy sepsis. Three children with wandering spleens were treated by a new splenopexy technique, the splenic snood. After detorsion, the spleens were wrapped in polyglycolic mesh and anchored by the mesh subdiaphragmatically in the left upper quadrant. All have retained their spleens which have remained where anchored up to a 4-year follow-up. The simplicity and technical ease of the splenic snood operation recommend it as an improved method to avoid splenectomy and safely normalize intraabdominal anatomy in the management of the wandering spleen.

A critical analysis of blood transfusion requirements in children with blunt abdominal trauma.

Over the past 2 years, 178 children with blunt abdominal trauma were admitted for observation. Fifty-five patients (31.5%) had intra-abdominal injury confirmed by computerized tomography (CT) scan, laparotomy, or postmortem examination. Forty-four children (80%) were managed with observation only; nine had other operations. Eleven patients (20%) required an operation for their intra-abdominal injuries. Thirteen patients died, ten from head or spinal injuries and three from intra-abdominal injuries (5.5%). Of 35 children with intra-abdominal injuries observed without any type of operation, 27 (77%) were not transfused (mean Pediatric Trauma Score [PTS] 8, Injury Severity Score [ISS] 19.3, average low hemoglobin [ALH] 10.1). The other eight were transfused an average of 49 cc/kg (mean PTS 4.5, ISS 26.5 ALH 6.1). Twenty children had operations. Eleven 11 (20%) of these were laparotomies; nine were transfused an average of 200.6 cc/kg (mean PTS 6, ISS 33, ALH 9). Nine had neurosurgical/orthopedic procedures (mean PTS 6.2, ISS 27.7), with six transfusions averaging 84.9 cc/kg (ALH 8.9). There were no significant complications. Blood transfusion was necessary only for 33 per cent of the observed cases, usually with multiple injuries. Blood should be transfused only to maintain hemodynamic stability (normal vital signs and tissue perfusion). Hemoglobin levels as low as 7 gm% do not mandate transfusion in children who are hemodynamically stable.

Modern treatment of cloacal exstrophy.

We have treated 12 newborns with cloacal exstrophy (10 classical and 2 variants) since 1980. Eleven infants underwent repair and they are all surviving; the one nonoperated infant died of pulmonary hypoplasia. There are six genetic females and six genetic males, five of whom are being raised as females. The initial operation consisted of separating the bowel from the bladder to create an intestinal stoma; closing the omphalocele; and reapproximating (5), closing (4), or leaving the exstrophied bladder undisturbed (2). The importance of creating a "tailgutostomy" instead of an ileostomy to prevent problems with diarrhea, dehydration, and acidosis is emphasized. There have been 71 subsequent operations in these 11 patients (28 general surgical, 25 urological, 9 neurosurgical, and 9 orthopedic). Quality of life, rather than survival, is now the major issue facing patients with cloacal exstrophy. All of these patients except one are neurologically normal. The defect is closed in all patients. Three patients wear no appliances, 7 wear one (gastrointestinal [GI]), and one wears two (GI and genitourinary [GU]). We developed a scoring system to analyze bowel and bladder continence: voluntary control = 3; control with an enema program or intermittent catheterization = 2; incontinence with a well-functioning stoma = 1; and incontinence without a stoma = 0. The best continence score is 6 (GU + GI). We currently have 7 patients with a continence score of 1 (colostomy + incontinent bladder); 1 with a score of 2 (ileostomy + incontinent ureteroenterostomy); 2 with a score of 4 (enema program + continent urinary diversion); and 1 with a score of 5 (enema program + continent bladder).(ABSTRACT TRUNCATED AT 250 WORDS)

Biliary atresia: an evolving perspective.

From 1967 to 1984, 50 of our patients with extrahepatic biliary atresia had surgical exploration. Of 40 biliary drainage procedures, bile drained in 21 (52%). Thirty-four patients had portoenterostomy, three had portocholecystostomy, and the most recent six patients had a valved hepatoduodenal conduit. Successful biliary drainage was related to the presence of microscopic ducts at the porta hepatis in 20 of 21 infants. Twenty patients are alive, 12 from two to six years postoperatively (one with a liver transplant). Seven have normal serum bilirubin values. Height and weight exceed the 50th percentile in 5/15 patients studied. Multiple episodes of cholangitis have occurred in 11 patients with portoenterostomy and two with hepatoduodenal conduits. In 12 patients, hemorrhage from the stoma necessitated closure of the stoma before 1 year of age. Five of the six patients with hepatoduodenal conduit are alive two years postoperatively.

Characteristics of children with endoscopically proved chronic bronchitis.

This study evaluated by chart review the clinical, allergic, pathologic, and immunologic characteristics of 20 children found to have chronic bronchitis (CB) by bronchoscopic evaluation, including 13 children in whom CB was documented by endobronchial biopsy. Two additional children likely to have had CB also are described. In this study group, all of the patients were believed to have asthma as well. Chronic bronchitis was predicted by chronicity of symptoms and incomplete response to bronchodilators and corticosteroids, but it was not predicted by a history of allergy or laboratory evidence of systemic infection or inflammation. In the children described herein, CB often was associated with an IgG subclass abnormality. Bronchoscopic evaluation documented CB and provided biopsy and secretion samples. Although the histomorphic findings were heterogeneous, patients with CB usually had white blood cells present on Gram stains of secretions in addition to mononuclear cell infiltrates on biopsy specimens. Chronic bronchitis in these children seems to be distinct from CB in adults. Further studies will be needed to define CB in children.

Cloacal exstrophy: 18-year survival of untreated case.

A patient is described who was 18 years old and attending high school when initially treated for cloacal exstrophy. The history, embryology and treatment of cloacal exstrophy are discussed, emphasizing that this congenital anomaly is compatible with a useful and happy life.

Significance of absent vas deferens at hernia repair in infants and children.

An absent vas deferens may be associated with unilateral renal agenesis or undiagnosed cystic fibrosis. Such patients should be further evaluated with a sweat chloride and intravenous pyelogram. The finding of absent vas deferens during exploration for an undescended testis does not provide absolute evidence for absence of the testis, since these structures have independent embryologic origins.
