title: Distal decompression and proximal feeding for nutritional support during bowel obstruction.
abstract: The treatment for acute mechanical intestinal obstruction is a timely operation. A select group of patients may, however, be nutritionally supported with continual administration of elemental diet proximal to long tube decompression under two sets of circumstances: 1. while awaiting spontaneous or treatment-induced resolution of the underlying process, and 2. while reversing catabolism during evaluation prior to operation. Eleven patients with chronic intermittent bowel obstruction were studied: six with obstruction involving radiated small bowel, three with an acute exacerbation of chronic inflammatory bowel disease, one with obstruction secondary to an intra-abdominal phlegmon and one with a segmental motility problem. They received nutritional support with continual gastrointestinal administration of elemental diet proximal to long tube decompression after initial observation for signs or symptoms of altered intestinal viability and stabilization of fluid and electrolyte status. Six of the 11 patients eventually required operation. All patients maintained body weight and three gained weight. Mean nutritional input was 1,873 calories and 12.6 gm nitrogen/day. There were no complications related to the technique of proximal feeding and distal decompression because of careful patient selection and appropriate administration of elemental diet under carefully controlled guidelines.
