ABSTRACT
Digestive graft-versus-host disease (GVHD) is a frequent complication after bone marrow transplantation, but small bowel obstruction is an extremely rare event. We present herein the first pediatric series of 4 cases of small bowel obstruction after bone marrow transplantation with detailed gross, histological data and their genetic status of the NOD2 gene. All patients had a history of severe acute GVHD treated by immunosuppressive agents and/or infliximab (in 3 cases). Acute or progressively worsening abdominal pain accompanied by small bowel occlusion occurred 5-16 months after graft, and computed tomographic scan revealed multiple small intestinal stenoses. Failure of intensive medical treatment led to surgical resection of affected loops. Stigmata of acute (apoptosis of crypts and satellitosis) and chronic GVHD features (submucosal fibrosis and serosae sclerolipomatosis), as well as extensive ulcerations, were observed in all ileal specimens. NOD2 mutation was found in only 1 patient. The follow-up showed successful outcome after surgery.
