Gastric outlet obstruction secondary to acid ingestion in children.

Background/purpose: Gastric outlet obstruction (GOO) is a well-known complication of acid ingestion. However, most reports deal with adults. In this report, the authors present their experience with the treatment of acid-induced GOO in children.

Methods: The records of patients admitted for unintentional ingestion of corrosive agents between 1980 and 2002 were reviewed retrospectively. Data concerning age at ingestion, type of ingested substance, time between ingestion and the first signs of GOO, weight loss, treatment, complications, duration of hospital stay, and long-term follow-up were reviewed.

Results: GOO was not observed in any of the children admitted for alkaline ingestion, whereas GOO developed in 8 of 98 children (8.2%) in a mean period of 26.7 +/- 10 days after the ingestion of acid substances. Presenting symptoms were frequent nonbilious vomiting and marked weight loss. All had pyloric obstructions in the upper gastrointestinal series and required surgical intervention. Gastrojejunostomy was the operation of choice for all patients. Oral feedings were started on the third postoperative day. The complications were wound infection in 1 and upper gastrointestinal bleeding in another in the early postoperative period. Mean follow-up is 8.33 +/- 4.45 (4.8-18.7) years. No late complications such as marginal ulcus or stricture at the anastomosis site were observed in the series.

Conclusions: Treatment of GOO with gastrojejunostomy gives good long-term results in children. This procedure is safe and causes minimal morbidity particularly in patients without extensive gastric damage.
