To study the functional aspects of the transposed stomach in the thoracic cavity and its effects on other organ systems.

Patients and methods:
Children who had undergone gastric transposition more than 5 years ago were evaluated for symptoms, anthropometry, anaemia, duodenogastric reflux, pulmonary function, gastric emptying, gastric pH, gastroesophageal reflux and stricture, gastric motility, and gastritis and atrophy on histological examination of gastric mucosa.

Ten children were evaluated at a median follow-up of 90.5 months. On evaluation of symptoms, nine children were satisfied with the overall outcome. All patients had their weight and 7 patients had height less than 3 rd percentile for their respective age. Anaemia was present in 7/10 children. On evaluation with hepatobiliary scintigraphy, duodenogastric reflux was present in only 1 patient. Mass contractions of the transposed stomach were present in two thirds of the children. The mean gastric emptying t1/2 was 39.1 minutes. Pulmonary function tests were suggestive of restrictive lung disease in all the patients. Forced vital capacity (FVC) and forced expiratory volume in 1 sec (FEV1) were worse in children who underwent transposition or diversion following oesophageal anastomotic leak. Acid secretion was preserved in most patients with episodes of high gastric pH during sleep in nearly half. Mild gastritis was present in all patients where as mild atrophy of the gastric mucosa was observed in only 1child. Helicobacter pylori were positive in 3/ 8 children. Barium swallow demonstrated reflux in 2 children.

Most children with transposed stomach remain asymptomatic on follow up. However, subclinical abnormalities are detected on investigations, which need close observation as they can manifest later in life.

    ABSTRACT: Purpose When restoration of the anatomical continuity in case of long gap esophageal atresia (LGEA) is not feasible, esophageal replacement surgery becomes mandatory. The aim of this paper is to critically compare the experience of two tertiary referral centers in The Netherlands performing either gastric pull-up (GPU) or jejunal interposition (JI). Methods Retrospective chart review of all the patients with LGEA who underwent GPU in the University Medical Center Groningen and JI in the University Medical Center Utrecht. Main endpoints were short term morbidity, mortality and long term functional outcome (digestive functioning and growth). Descriptive analyses conducted using Mann–Whitney U test for continuous variables and Fisher's exact test for categorical variables. Results Nine children underwent GPU and 15 JI. Median age (years) at last follow up was fourteen (GPU) and eight (JI). One patient died, 10 years after JI. No grafts were lost. Perioperative anastomotic complications were reported more often after JI (73% vs. 22%, p = 0.03). However reintervention rate was the same in both groups (33%). Among long term outcomes, functional obstruction was not registered after GPU, while it was recorded in 46% after JI (p = 0.02). No other significant differences were found apart from some tendencies concerning full oral nutrition and gastroesophageal reflux (GPU > JI). Conclusion Comparative data from this study reveal no mortality but significant morbidity in both groups. No graft was lost. Although not statistically different as a result of small patient numbers, clinically important differences regarding gastrointestinal system were noted. Growth should be monitored closely in both groups.
