Reduced parenteral nutrition requirements following anastomosis of a short residual colonic segment to a short jejunum.

A 22-year-old man suffered an acute small bowel infarct leading to extensive bowel resection, resulting in only 20 cm of jejunum to a jejunostomy, although he also had 50 cm of residual colon with a mucous fistula. The patient was out on long-term home parenteral nutrition (PN) but endured high stomal losses of 5-6 L per day and, despite all conventional measures, required 6.1 L of fluid (including PN) and 555 mmol sodium per day. Although body mass index was maintained, he suffered debilitating malaise and recurrent episodes of catheter-related sepsis and also developed persistently abnormal liver function tests. He was considered a potential intestinal transplant patient, but before taking that step, he opted for reanastomosis of his residual colon to his jejunum, ending in a colostomy. At surgery, only 30 cm of additional bowel lengthening could be achieved, but despite this, the patient's stomal losses reduced to 2.5 L per day, intravenous fluid requirements reduced to 4.1 L per day, and liver function normalized. The patient also gained 7.5 kg despite no change in PN caloric prescription, and his quality of life was dramatically enhanced. The case illustrates that even a small length of colon can grant significant improvements, probably via improvements in small bowel transit and adaptive changes, better sodium and water resorption with decreased hyperaldosteronism, and enhanced energy and nitrogen recovery. Reanastomosis of defunctioned colon should therefore always be considered a management option in short bowel syndrome.
