The frequency of gastroesophageal reflux disease in pediatrics has increased. There is not a clear explanation, some believe there is more awareness of the disease, others believe that new formulas, which are richer in nutrients, may irritate the gastrointestinal tract of the infant. Clinically, children present with regurgitation-malnutrition, respiratory disease, and esophagitis. The medical treatment aims to improve the eating techniques, to decrease the gastric acid output, and to improve the motility function of the esophago-gastrointestinal tract. Surgical treatment is rarely needed.

Steatosis and steatohepatitis are associated with obesity. Despite florid histological changes, patients with non-alcoholic steatohepatitis generally remain asymptomatic, and it usually runs a relatively benign course. An elevated insulin level may be important in the pathogenesis. There is a marked regression of fatty changes after weight reduction. In obese subjects the risk of developing gallstones is increased due to an increased saturation of gallbladder bile with cholesterol and possible gallbladder stasis. During weight reduction with very low calorie diets the incidence in gallstones increases probably because of an increased saturation of bile during the loss of weight. Ursodeoxycholic acid appears to be a promising prophylactic agent. Chenodeoxycholic acid is not useful for these subjects. There is controversy over whether obesity contributes to gastroesophageal reflux and gastric emptying disturbances. There are changes in gastrointestinal peptide plasma levels in obesity but it is not clear if this contributes to its development. The risk for high-risk colorectal adenomas and carcinomas is reported to be increased in obese males. Vertical banded gastroplasty and gastric bypass procedures are nowadays the surgical options for the treatment of obesity. Nutritional deficiencies, particularly of vitamin B12, folate and iron are common after gastric bypass and must be sought and treated. Dumping is another potential complication of this operation. If stenosis and gastric outlet obstruction develop endoscopic dilatation is a good therapeutic option.

Malnutrition and growth failure are frequent clinical consequences of human immunodeficiency virus (HIV) infection in children. Tube feeding is a means by which to increase the enteral intake of nutrients. We examined the effect of tube feeding in 18 children, median age 6 months (range, 3-159). Tube feedings were initiated due to growth failure in all, which was also associated with dysfunctional swallowing or aspiration in seven children and gastroesophageal reflux in two. Tube feedings were infused via nasogastric tube (n = 4) or gastrostomy tube (n = 14) and were continued for a median of 8.5 months (range, 2-24). Stoma complications developed in three children with gastrostomy tubes; these were the only tube-related side effect. Tube feedings were discontinued due to noncompliance (n = 3), gastrostomy leakage (n = 2), intolerance (n = 2), and death (n = 3). Anthropometric changes were evaluated comparing mean standard deviation scores (Z) before and after tube feeding. Tube feeding resulted in significantly increased weight for age (Z, -2.13 +/- 0.7 vs. -1.46 +/- 1.4; p = 0.04), weight for height (Z, -1.07 +/- 1.0 vs. -0.13 +/- 1.0; p = 0.004), and arm fat area (Z, -1.75 +/- 1.3 vs. -0.62 +/- 1.2; p = 0.01). However, tube feeding did not result in significant changes in height for age (Z, -1.93 +/- 0.8 vs. -1.74 +/- 1.6) or arm muscle area (Z, -1.24 +/- 0.9 vs. -0.57 +/- 1.2). Tube feedings effectively increased the weight of HIV-infected children in this study, but they were not sufficient to correct linear growth deficits.

Two cases of coarctation complex (CoA + VSD + PDA) associated with congenital esophageal atresia (Gross type C) were successfully treated with esophageal and two-staged cardiac surgery. The perioperative management of the two cases is discussed with special reference to circulatory, respiratory and nutritional problems. Case 1; A newborn was diagnosed as esophageal and cardiac anomalies and gastrostomy was performed followed by end to end anastomosis of the esophagus under receiving Prostaglandin E1 infusion. Although subclavian flap angioplasty (SFA) and pulmonary artery banding (PAB) were performed 1 month later, she had recurrent respiratory complications and malnutrition postoperatively due to bronchomalacia and gastroesophageal reflux (GER). Case 2; A newborn was diagnosed as esophageal atresia and underwent corrective surgery of it on the 1st day of life. After esophageal surgery congestive heart failure (CHF) developed progressively and CoA complex was evident by echocardiography 5 days later. SFA and PAB were performed 26th day of life. In spite of the palliative surgery for cardiac lesions, both patients had growth failure because of CHF, respiratory complications and malnutrition. As soon as the circulatory and respiratory condition improved, corrective surgery was performed and resulted in full recovery.

The authors reviewed 64 jejunostomies performed in 57 patients. Data were collected regarding complications and performance of the catheters. Patient diagnoses were grouped as follows: cystic fibrosis (25), neurological impairment (14), and miscellaneous other (25). Indications were malnutrition (43), inability to feed (17), and gastroesophageal reflux (4). Complications were compared between these groups. The age range was 7 days to 23 years. There were 251 tube changes over 142 years of cumulative site patency, for an average of 1.8 tube changes per year and an average life of 2.2 +/- 2.4 years per site. The longest duration was 11.7 years. Four tube changes resulted in intraperitoneal insertion (6.2% of changes). The overall complication rate was 37.5%. The major and minor complication rates were 21.9% each. Some patients had more than one complication. Stratification of complications by diagnosis showed that the highest incidence was among the neurologically impaired children (64%), followed by those with cystic fibrosis (32%) and then others (28%). Sixty-four percent of major and 54% of minor complications occurred within the first 6 months. The mortality rate was 4.7%. Infections requiring intravenous antibiotics occurred in 9.4% of the sites, at an average site age of 8.7 +/- 7.7 months. Tube dislodgment requiring surgical replacement occurred in 9.4% of the patients. Our mortality and complication rates compare favorably to those of previously reported series. Surgical jejunostomy is a reliable long-term solution to feeding but is associated with a significant risk of complications, especially in neurologically impaired children. The risk is greatest in the first 6 months after insertion, then decreases as the site "matures."

In children with major neurologic impairment, gastrostomies are often used to alleviate malnutrition and feeding difficulties. There has been a trend toward performing "protective" antireflux surgery in these children. Nineteen children with major neurologic impairment and feeding failure were prospectively evaluated and followed up after placement of a percutaneous endoscopic gastrostomy (PEG) without any antireflux procedure. Mean age at PEG placement was 34 months with mean follow-up of 20.7 months. All parents would recommend PEG to families with disabled children, and if given the chance, 95% would elect PEG again for their child. No child developed choking, gagging, or retching postoperatively. At the time of follow-up, postoperative gastroesophageal reflux did not appear to be a major clinical problem.

Gastrointestinal involvement is commonly found in scleroderma. Gastrointestinal symptoms may be the presenting symptoms for the diagnosis and may precede the actual diagnosis by months to years. The esophagus is the most frequently affected, but functional problems of the anorectum, small bowel, colon, and stomach may occur. The pathophysiologic mechanism appears to be one of smooth muscle atrophy and, to a lesser degree, fibrosis. These changes result in gastrointestinal motility disturbances and may cause GERD, pseudo-obstruction, bacterial overgrowth, and defecatory disorders. Malnutrition may be a serious consequence. The evaluation of a particular symptom in a patient with scleroderma may lead to treatment strategies that improve the patient's sense of well-being and quality of life.

The clinical histories of 46 adult patients (24 men and 22 women, mean age 20.6 +/- 5.1 years) diagnosed of cystic fibrosis were reviewed evaluating the digestive alterations. The age at diagnosis of cystic fibrosis was 5.63 +/- 5.3 years (range: newborns-19 years). The initial diagnosis was established by ileus meconium, in four, lung disease in 15, steatorrhea in 12, lung disease and steatorrhea in 13 and following the diagnosis of cystic fibrosis in siblings in two. Four patients presented ileus meconium, nine occlusive syndrome of the distal intestine, 42 steatorrhea (20 severe, 12 moderate and 10 mild), with the severity of the steatorrhea not being associated with the severity of the respiratory insufficiency. Two patients presents rectal prolapse, five gastroesophageal reflux syndrome (four with hiatal hernia), six cholelithiasis, one recurrent pancreatitis without detection of biliary lithiasis, one neonatal cholestasis and 10 malnutrition (five severe and five moderate) fundamentally in relation to the severity of the lung disease and, to a lesser degree, liver disease. In 10 patients chronic liver disease was diagnosed corresponding to established cirrhosis in seven, indicating liver transplantation in two. In most cases, the liver disease was already manifest in adolescence even in the cirrhotic stage. Cholangiography by magnetic resonance was useful in the study of liver disease showing abnormalities which imitated primary sclerosing cholangitis. Treatment with ursodesoxicholic acid at a dosis of 20 mg/kg/day led to a significant decrease in the transaminase values and overall of gammaglutamyltranspeptidase but did not avoid complications in the cirrhotic stages. Genetic studies performed in 36 patients detected the delta F508 mutation in 69.4%, being found in almost all of the patients with ileus meconium, occlusive syndrome of the distal intestine, liver disease, cholelithiasis and malnutrition.

Reconstruction of the intestinal passage after a total gastrectomy is usually based on a direct esophagojejunostomy with end-to-side implantation of the afferent loop. The second principle of reconstruction is based on preservation of the duodenal passage. Long-term problems such as weight loss and malnutrition are further considerations that lead to the concept that gastric reconstruction should have the form of a reservoir. In addition to the construction of the reservoir itself, the clinical concern of avoiding gastroesophageal reflux is a further requirement for the choice of reconstruction type. Diversion of the duodenal content via a Roux-en-Y end-to-side anastomosis is considered to be the standard procedure. Interposition of a sufficiently long duodenal loop with maintenance of the duodenal passage also has the effect of preventing duodenal reflux. A theoretical advantage of this procedure is the linking of the motility of the duodenum with that of the interposed segment with improved synchronization of the aboral nutrient passage. When one considers complicated reconstructive procedures, the present literature suggests construction of a pouch is definitely functionally superior to the simple esophagojejunostomy. Whether the duodenal passage should be maintained or whether a Roux-Y technique should be used is a question that is still open for discussion.

In the pediatric population, gastroesophageal reflux most often presents in infancy as effortless regurgitation, but pathologic GERD is accompanied by signs of malnutrition, respiratory diseases, and esophagitis or its complications. Because of the distinctive pathophysiology predisposing infants to GERD, the diagnostic approach must begin with a thorough history that determines the extent of further diagnostic tests and the course of management. Empiric therapy assumes importance in infants with GERD because of the limited differential diagnoses in consideration. Conservative therapy is of utmost importance because of the unique provocative factors in the pathophysiology of infantile GERD. Prokinetic pharmacotherapy takes precedence over acid suppression because of the more important role of motility factors compared with acid secretion in infantile GERD.
