title: Adhesional small bowel obstruction after colorectal surgery.
abstract: BACKGROUND
  Acute clinical indicators of complications in colorectal surgery can be readily attained but it is much harder to gather indicators of long-term outcomes such as small bowel obstruction (SBO). However, with improved in-hospital data collection and coding such information is becoming available. The aim of the present study was to examine our own hospital database for SBO rates post-colorectal surgery.
  
  
  METHODS
  The database was searched and then the relevant medical records were reviewed of all patients admitted to Flinders Medical Centre (Bedford Park, Australia) between July 1999 and November 2002 with a diagnosis of SBO following a colorectal procedure during this same time period.
  
  
  RESULTS
  There were 21 patients that accounted for 28 readmissions from a total colorectal procedure group of 583 patients. The arbitrary subgroups were: 13/325 (4%) for colonic resections; 7/186 (3.7%) for rectal resections; 0/12 (0%) for laparotomies/other procedures; and 1/39 (2.6%) for stoma formation/reversals. The overall SBO rate requiring readmission was therefore 3.6%/pt in the 3 years. There was a large variation in the first readmission interval, 38% occurred within 3 months, 43% between 3 and 12 months, and 19% after 1 year. At the first readmission 38% of patients had operative treatment. The mean length of stay was 6.12 days for non-operative vs 21.62 days for operative treatment.
  
  
  CONCLUSIONS
  The reported rate of SBO of 3.6% (at 3 years time interval) is in accordance with other studies. With 38% of patients being treated operatively at first admission there is good acceptance for conservative management in non-strangulated SBO. The prolonged hospital stay for patients needing surgery warrants further investigation.
