BACKGROUND: Isolated small bowel injury (ISBI) related to abdominal blunt trauma is rare. Timely diagnosis could be difficult, especially in the absence of modern imaging and laparoscopic facilities. The determinants of mortality under such circumstances are unclear. METHODS: This study presents twenty three cases of ISBI related to blunt abdominal injury identified between January 2005 and December 2009 in a level III Hospital in Limbe, Cameroon. Data were retrieved from an ongoing prospective study on injuries and augmented by analysis of individual patient's files. We analysed information regarding modalities of diagnosis, delay between injury and diagnosis, operative findings, treatment and outcome. RESULTS: The ages of our patients ranged from 7 to 38 years with a mean of 19 years. Thirteen patients were children below the age of 16. The most frequent mechanism of injury was a fall (n=11). Associated lesions were identified in 7 patients. Delay between injury and diagnosis was above 12h in 16 patients. Fifteen cases were admitted with obvious signs of peritonitis. Erect chest X-ray identified a pneumoperitoneum in 11 of the 17 patients for whom it was requested. Most perforations were located in the ileum. A total of 7 complications occurred in 5 patients. These included 4 cases of post-operative peritonitis. Two patients with at least one associated lesion died. CONCLUSION: ISBI is seldom suspected. This causes delay in diagnosis and most cases present with a diffuse peritonitis. Early diagnosis and management in low income environment is likely to be improved by a greater awareness of clinicians about this injury, serial clinical assessment and repeated erect chest X-ray, rather than sophisticated tools such as CT scan or laparoscopy.
