ABSTRACT
Colon injury is far more common in penetrating injury than blunt trauma. Blunt trauma to the abdomen is more likely to damage solid organs such as the liver, spleen, pancreas and kidneys. Colon injury in blunt trauma is severe and is associated with other organ injuries, making its diagnosis difficult. However, isolated sigmoid colon injury in blunt trauma is rare. We report a case of 42 year old male who presented to us with blunt trauma to abdomen following a fall on iron Jaal (Grid) with slipping of one lower limb between two iron bars. The patient presented 4 days after injury with tenderness and guarding all over abdomen. X-ray abdomen was normal, ultrasonogram of abdomen showed presence of free fluid. Patient was operated on clinical basis. A single perforation of size 2 cm×1 cm was present in proximal sigmoid colon and there was no other injury. The perforated colon loop was mobilized and brought to anterior abdominal wall as colostomy. Isolated sigmoid colon injury is rare presentation. Initial radiologic investigations and clinical presentation may be misleading.
