Bolus obstruction by Ascaris lumbricoides.
Seventy-three cases of obstruction due to a bolus of Ascaris worms are reviewed. The diagnosis was made on the basis either of a characteristic palpable mass or a characteristic radiographic appearance. In 67 cases conservative treatment was successful. Six patients came to surgery, 5 because of deterioration. There were no deaths. The need for careful reassessment is stressed.
