Abstract
Gastric transposition (GT) has become a reliable alternative operation for oesophageal replacement in children. The aims of this study were to assess the long-term results of the operation and to study the function of the intrathoracic stomach. Current symptoms were assessed using a questionnaire and linear analogue scales. Lung function was measured using spirometry and plethysmography, and the results were corrected for height and expressed as a percentage of the predicted values for normal children. Gastric emptying was assessed using a dual isotope radiolabelled test meal (incorporating solid and liquid phases). Full anthropometric and haematologic data also were collected. The results are expressed as medians and interquartile ranges. Seventeen children were examined at least 5 years after GT; the median age was 9 years. Two children frequently had symptoms during swallowing. Four children had significant diarrhoeal episodes, and two had significant postprandial weakness or dizziness. Unexplained breathlessness was noted by four children. All but one child had lung function values that were lower than the mean predicted value for height. For example, the total lung capacity was 68%, and forced vital capacity (FVC) was 64%. However, the ratio of forced expiratory volume in 1 second (FEV 1) to FVC was normal. The gastric emptying study showed that the intrathoracic stomach in all subjects served as a conduit (rather than a reservoir) for both liquids and solids. Rapid emptying (>50%) in both phases occurred within 5 minutes of ingestion in 82% of the group. Thirteen children were between the 3rd and 97th percentiles for height, and 11 in this range for weight. Five children were anaemic (< 11.5 g/dL). In 11 of the tested samples, the serum ferritin was low, indicating depleted iron stores. GT is compatible with an entirely normal life and has allowed satisfactory growth and nutrition for the majority of subjects in this study group.
