A Primary Ileal Enterolith Presenting As Subacute Small Bowel Obstruction

Enteroliths are a rare cause of intestinal obstruction. We report here a case of 69 years female presented with signs of subacute intestinal obstruction to the department of general surgery in Meenakshi medical college, kanchipuram. She was able to pass flatus, but with cessation of bowel movements. Plain X-ray abdomen and CT Abdomen was done subsequently, which shows a radiopaque shadow in the distal portion of ileal lumen. A choledochal fistula was ruled out. A provisional diagnosis of Subacute intestinal obstruction was made. On Exploratory Laparotomy, multiple ileal strictures with mesenteric edema noted. An enterolith was delivered from one of the segments between two strictures, followed by segmental Ileal resection anastamosis. It was a case of Primary Enterolith, formed due to stasis between ileal strictures leading to subacute intestinal obstruction. Enterolith presents with varied clinical presentation and this unusual case warranted surgery, which resolved her symptoms.
