Intestinal obstruction in children due to Ascariasis: A tertiary health centre experience

PK Mishra, A Agrawal, M Joshi, B Sanghvi, H Shah, SV Parelkar


Background: Ascariasis is the infestation by the largest intestinal nematode of man, a common problem in the tropics attributed to poor hygienic and low socioeconomic
conditions. The aim of this research is to analyse the presentation, diagnosis and management of bowel obstruction caused by Ascaris lumbricoides, with special emphasis on the role of conservative management. Materials and Methods: This is a single centre, two
consultant based 5 year retrospective study of childhood intestinal obstruction due to worms. Diagnosis in the suspected patients was based on history of passage
of worms per mouth or rectum and on x-ray and ultrasonography fi ndings. Only the patients of intestinal obstruction with documented evidence of roundworm
infestation were included in the study and were followed for one year. Results: One hundred and three children with intestinal obstruction due to Ascaris lumbricoides
were treated in the past five years at our centre. Abdominal pain was the most common presentation seen in 96 children followed by vomiting in 77 children. 20 children had history of vomiting worms and another 43 had history of passing worms in stool. Abdominal
tenderness was present in 50 children, 48 had abdominal distension of varying degree, 50 had abdominal mass due to worm bolus, and 16 had or developed abdominal
guarding or rigidity. All the children were managed as for acute intestinal obstruction along with hypertonic saline enema. The aim of management was “to starve the worm
and hydrate the patient”. 87 patients (84.47%) responded favourably and were relieved of the obstruction by the conservative management, 16 children (15.53%) had
abdominal guarding or rigidity and underwent emergency exploration. Conclusion: Roundworm obstruction should be considered in the differential diagnoses of all cases
of intestinal obstruction in children. Clinical history and examination along with X-ray and ultrasonography are very helpful for diagnosis of this surgical emergency.
Most cases of intestinal obstruction due to Ascaris can be managed conservatively; however emergency surgery is needed in patients with abdominal guarding and rigidity.
