Calcified stone in intestinal blind loop after 60 years of surgical treatment of complex jejunal atresia: an attempt to understand an enigma.

A 60-year-old woman was presented in emergency department with abdominal pain and vomiting for 1 day. She was known to have seropositive rheumatoid arthritis. Importantly, she was treated surgically for complex jejunal atresia and duplication surgery, when she was 6 days old. CT scan showed intestinal obstruction secondary to intussception. Patient had lapartomy and operative findings revealed side-to-side anastomosis with gut duplication 10 cm distal to duodenal jejunum junction (due to her previous surgery during infancy). Redundant part of the loop dilated up to 300 mL with large hard stone (4×3.5 cm) was excised. Patient recovered well postoperatively and was discharged to go home. To our knowledge, this is the first case report to show formation of large stone 60 years after surgical treatment of complex jejunal atresia and duplication surgery in infancy.
