“…The results of this study would therefore support the conclusions of both Redfern and others (1961) and Singleton and Montalbo (1968). The increased exsorption by distended small bowel may be partly explained by the associated venous congestion (Shields, 1969, but it is more difficult to begin to explain the decreased insorption which is caused by decompression.…”

SUMMARYA study has been made of the intestinal handling of water and electrolytes following the relief of smallbowel obstruction. A new technique has been described for perfusing the ileum of conscious animals. It has been shown that the ileum secretes water and electrolytes for at least 48 hours following the relief of obstruction, and that decompression increases this fluid loss during the first 6 hours after surgery. It is suggested that the fluid and electrolyte requirements during this period will be increased when decompression is performed.SMALL intestinal obstruction is a common surgical problem ( Table I) and Hoguet (1912) showed, in dogs, how important the loss of fluid and electrolytes from the obstructed gastro-intestinal tract was. Later it was suggested that this fluid loss was due to increased biliary, pancreatic, and gastro-intestinal secretions, but the exact role of the small bowel was not defined until Shields (1965) showed that obstructed bowel begins to secrete, rather than absorb, water and electrolytes within 12 hours of the onset of intestinal obstruction and that the rate of secretion increases with time. Nothing, however, is known about the handling of water and electrolytes by the small bowel after * Present address: Senior Registrar, St. Thomas's Hospital, London. second operation. At this second laparotomy the tubes for intestinal perfusion were positioned in the loop of bowel immediately above the site of the obstruction.The subsequent handling of water and electrolytes was studied by perfusing the bowel 6, 24, and 48 hours after the second operation. Since perfusion has not previously been used to study the handling of water and electrolytes in the conscious animal, the technique is described in detail (Fig.

“…Two studies have produced conflicting answers. Redfern, Close, and Ellison (1961) suggested that the fluid loss 6 hours after operation was increased when decompression was performed, while Singleton and Montalbo (1968) claimed that the fluid loss 24 hours later was greater if decompression was not performed.…”

“…Those patients in whom an operation is per¬ formed for small-bowel obstruction in the absence of frank bowel infarction are invariably seen to have a plethoric bowel wall suggesting a heightened local blood flow in the obstructed segment. 25 The purpose of this study was to investigate regional blood flow and central hemodynamic changes during smallintestinal obstruction in an animal model that is sufficiently similar to that of mechanical small-bowel obstruction in man, thereby allowing clinically relevant inferences to be made more readily.…”
