Complications in patients with neurological impairment after gastrostomy.

BACKGROUND: Neurological impairment (NI) is responsible for most conditions that require a permanent gastrostomy tube. The present study assessed the occurrence of short- and long-term complications after video-assisted gastrostomy (VAG) in patients with NI. METHODS: The incidence of short- (<6 months) and long-term (over 2 years) complications of VAG were analyzed in a retrospective study. The differences between the incidence of the complications of VAG according to the age at surgery (≤15 years vs. ≥16 years) were also evaluated. The short- and long-term complications observed were granulation tissue formation, infection requiring antibiotic treatment, skin problems, perigastrostomy leakage, vomiting, accidental tube dislodgement, dumping syndrome, ileus, and peritonitis. RESULTS: Eighty-two patients were evaluated for short- and long-term complications. The long-term complication rate was significantly lower than the short-term complication rate (P = 0.0026). Onodera's prognostic nutritional index before VAG in patients with long-term complications was significantly lower than in patients without such complications (P = 0.046). The incidence of long-term granulation tissue formation, infection, and vomiting were significantly lower than those of similar short-term complications. Long-term skin problems were associated with short-term skin problems (odds ratio: 18.95; 95% confidence interval: 4.53-92.98; P < 0.001). The number of patients ≥16 years old with short- and long-term skin problems was significantly higher than in patients ≤15 years old (P = 0.0014 and P = 0.0073, respectively). CONCLUSIONS: The incidence rate of granulation tissue formation and infection after VAG were lower in the long term than in the short term. However, patients ≥16 years old presented with persistent complications.

Dietary chloride deficiency due to new liquid nutritional products.

BACKGROUND: In infants the ingestion of chloride-deficient formulas was previously reported to cause hypochloremic metabolic alkalosis and hypokalemia, which is referred to as dietary chloride deficiency syndrome. Since that time, however, dietary chloride deficiency has not been commonly recognized. The aim of the present study was to evaluate the clinical features of dietary chloride deficiency syndrome caused by the ingestion of newly marketed liquid nutritional products. METHODS: This was a retrospective chart review of 59 patients with severe motor and intellectual disability (SMID); they had been given newly marketed liquid nutritional products that were later found to be chloride deficient. RESULTS: Eight-nine weeks after changing to the new liquid nutritional products, clinical symptoms and laboratory abnormalities were noted. The main clinical finding was weight loss; 22% of subjects lost >5% of their bodyweight. A small number of the subjects had a mild bowel movement disorder; diarrhea and constipation were found in six and three patients, respectively. Hyponatremia, hypokalemia, and hypochloremia occurred in 33.9%, 44.5%, and 50.8%, respectively. CONCLUSIONS: Chloride-deficient liquid nutritional products can cause weight loss, hypochloremic metabolic alkalosis, and hypokalemia in persons with severe motor and intellectual disability.
