An experimental evaluation of segmental reversal after massive small bowel resection

Abstract

Summary The technique of reversal of a distal segment of residual small intestine was applied to the management of massive resection. A controlled evaluation was carried out in dogs into the effects of segmental reversal on the proximal remnant after the distal 75 per cent of the small bowel had been resected. The variables studied were survival, body weight, glyceryl tri(palmitate-1-14C) absorption and mouth-to-caecum transit time. Animals subjected to resection alone had accelerated intestinal transit, poor absorption, serious weight loss and a high early mortality. It was clearly demonstrated that segmental reversal after resection produced marked and progressive delay in transit time from mouth to caecum, sustained improvement in fat absorption and body weight and enhanced survival.
