Management of Intestinal obstruction
Intestinal obstruction due to ascariasis should be managed conservatively by:[1]
- Nasogastric decompression
- Fluid and electrolyte repletion
- Antihelminthic therapy once bowel motility is restored. Piperazine causes flaccid paralysis of the worms and this can help relieve the obstruction.
- Complete obstruction with inadequate decompression, lack of response within an interval of 24-48 hrs, volvulus, intussusception or perforation should be managed surgically.
