title: Factors influencing bowel function following total abdominal colectomy.
abstract: OBJECTIVE
  The purpose of this study was to determine which factors influenced bowel function following total abdominal colectomy.
  
  
  METHODS
  Thirty-two patients who had undergone total abdominal colectomy were studied with regard to factors that are classically thought to influence bowel function, namely, residual stump length, transit time, and rectal stump manometry. In a limited subset of patients, anal manometry was done also.
  
  
  RESULTS
  Transit time was the best predictor of bowel function following total abdominal colectomy. This was followed by stump length. If transit time was short, then stump length became important in predicting the occurrence of diarrhea following total abdominal colectomy.
  
  
  CONCLUSIONS
  Two factors have an important influence on bowel function following total abdominal colectomy: transit time and rectal stump length. Rectal stump length is an anatomic factor that can be controlled by the surgeon. In total abdominal colectomy, rectal stump length of at least 20 cm is necessary if the patient is to have satisfactory postoperative bowel function. This may not always be possible. In these patients, modification of diet to influence transit time and methods to increase rectal compliance will be necessary.
