title: Results of endotoxin absorption after a subtotal resection of the small intestine and a right hemicolectomy for severe superior mesenteric ischemia.
abstract: OBJECTIVE
  The purpose of this study is to analyze the results of endotoxin absorption therapy after a subtotal resection of the small intestine and a right hemicolectomy for severe superior mesenteric ischemia.
  
  
  METHODS
  From April 1980 through August 1999, 82 patients with severe superior mesenteric ischemia were operated on an emergency basis, and they were divided into two groups. Group 1 (n = 51), did not undergo postoperative endotoxin absorption therapy, while group 2 (n = 31), underwent this therapy. The two groups were compared based on the outcome variables.
  
  
  RESULTS
  When the number of risk factors was 1 or 2, the mortality rate in group 2 was significantly lower than in group 1 (p < 0.05). For postoperative lung or liver failure, the mortality rate was significantly higher in group 1 than in group 2. For an intraabdominal abscess, the mortality rate was significantly higher in group 1 than in group 2. Twenty-two of the thirty-one patients in group 2 survived. In the surviving cases, this therapy significantly decreased the intravenous concentration of endotoxin (p = 0.04). As for the fatalities (n = 9), no significant change in the concentration of endotoxin before or after endotoxin absorption was recognized. By the first postoperative month, the survival rate was significantly lower in group 1 than in group 2 (58.8% vs. 71.0%, P = 0.04).
  
  
  CONCLUSIONS
  In conclusion, we may now safely say that both stoma and a resection are recommended while endotoxin absorption using blood filtration may also be an effective additional therapy for post-operative septic shock.
