Colon interposition in children

Abstract

Abstract Since 1960 we have performed 80 colonic interpositions on 79 children. We present a retrospective review of their progress. Sixty-nine interpositions were for long-gap oesophageal atresia, while the remainder followed oesophagectomies, eight for strictures and two others. Overall, the transthoracic route was used in 69 per cent of cases, while 29 per cent were retrosternally placed and one was retropleural. The mean follow-up was 11.08 years. The mortality rate was 12 per cent, with one-third of deaths unrelated to the operation. Graft failure, which occurred on eight occasions (10 per cent), was due to ischaemia in four, intractable stricture in two and stomal ulceration in two. Leakage from the proximal anastomosis occurred in 31 per cent of cases and stricture formation in 27 per cent. Thirty per cent of patients complained of acid reflux, of whom one-third developed stomal ulceration. We present data concerning other complications, including long-term recurrent respiratory infections, malabsorption, gastrointestinal haemorrhage, diarrhoea, intestinal obstruction and redundancy of the graft. Staging the procedure did not affect the outcome, however the higher incidence of serious complications encountered following retrosternal interposition finally led us to abandon this procedure in favour of the transthoracic route. There has been little improvement in the growth rate, but in terms of swallowing ability the outcome was satisfactory in 94 per cent of cases.
