title: [Massive intestinal resection. Nutritional adaptation process].
abstract: BACKGROUND
  Massive small bowel resection (MSBR) with a remnant jejunum shorter than 60 cm produces severe water, electrolytes, vitamins and protein-caloric depletion. While waiting for a viable intestinal transplantation, most of MSBR patients depend on total parenteral nutrition (TPN).
  
  
  METHODS
  32 years old male, with MSBR due to sectioning trauma of the superior mesenteric artery root. First surgical intervention: jejunostomy with small bowel, right colon, and spleen resection. Six months later: jejunocolic anastomosis with 12-cm long jejunum remnant and prophylactic cholecystectomy.
  1st phase. Hemodynamic stabilization and enteral stimulation (6 months): TPN + enteral nutrition with elemental formula + oral glucohydroelectrolitic solution (OGHS) + 15 g/d of oral glutamine + omeprazol. Clinical course indicators: biochemistry, I/L balance. 2a phase. Digestive adaptation with colonic integration (8 months): replacement of TPN by part-time peripheral PN. Progressive cooked diet complemented with pancreatic poly-enzyme preparation, omeprazol, OGHS, glutamine, elemental formula. Clinical course indicators: biochemistry, diuresis, weight and feces. 3a phase. Auto-sufficiency without parenteral dependence: fragmented free oral diet supplemented with pancreatic poly-enzyme preparation, mineralized beverages, enteral formula supplement, Ca and Mg oral supplements, oral multivitamin and mineral preparation, monthly IM vitamin B12. Current situation actual (52 months): slight ponderal gain, diuresis > liter/day, 2-3 normal feces, no clinical signs of any deficiency and normal blood levels of micronutrients.
  
  
  CONCLUSIONS
  It may be possible to withdraw from PN in MSBR considering, as in this case, favorable age and etiology and early implementation of an appropriate protocol of remnant adaptation.
