Pediatric short bowel syndrome: adaptation after massive small bowel resection.
BACKGROUND
Short bowel syndrome (SBS) develops after massive small bowel resections. Patients with less than 12 cm of jejunoileum have a slim possibility of being weaned from parenteral nutrition (PN).


METHODS
In a retrospective review of records of consecutive patients with SBS, 8 patients were evaluated for treatment by adaptation and weaning from PN. These included 4 patients with class I SBS (0-10 cm of small bowel), one with class II SBS (>10-25 cm), one with class III SBS (>25-50 cm), and 2 with class IV SBS (>50-75 cm). Adaptation was assessed by measuring growth in the small bowel and the ability to be weaned from PN.


RESULTS
Adaptation was achieved primarily by extending the length of jejunoileum by approximately 450% over the first 2.5 years after resection and by increasing the degree of colonic fermentation and absorption of nutrients. As of July 1, 2005, all of the patients were off PN, with the exception of 2 patients with class I-A SBS: patient 3 had a remaining jejunoileum of only 2.5 cm and patient 4 had a remaining jejunoileum of 9 cm but developed eosinophilic enterocolitis. These 2 patients continued with PN on alternate months.


CONCLUSIONS
Bowel growth after massive small bowel resection provides an objective parameter of adaptation and a means of predicting ability to be weaned from PN. Aggressive nutritional support makes even patients with class I SBS, whose disease was previously considered hopeless, likely candidates to achieve freedom from PN.
