title: Comparison of massive vs. repeated resection leading to short bowel syndrome.
abstract: Short bowel syndrome can result from either a single massive intestinal resection or repeated lesser resections, which might have prognostic implications. The aim of this study was to compare patient populations and outcome of short bowel syndrome caused by massive and repeated resection. The records of 95 adult patients with short bowel syndrome evaluated over a 20-year period were reviewed. Massive resection was performed in 72 patients (76%) and repeated lesser resections in 23 patients (24%). Patients undergoing massive resection were more likely to be more than 70 years of age (26% vs. 9%, P <0.05). Mesenteric vascular disease was more prevalent among patients undergoing massive resection (39% vs. 9%, P <0.05), whereas Crohn's disease was less prevalent (1% vs. 35%, P <0. 05). Distribution of remnant length, presence of the ileocecal junction, and presence of a stoma were similar. Patients undergoing massive resection were more likely to require parenteral nutrition after the first year (56% vs. 23%, P <0.05). Patients with very short remnants (<60 cm) were more likely to receive parenteral nutrition after massive resection (95% vs. 60%, P <0.05). Thirty-day mortality was higher after massive resection (24% vs. 4%, P <0.05). However, those surviving 30 days had similar survival rates at 1 year and 5 years after massive and repeated resections. Patients undergoing massive vs. repeated resections are different with respect to age, underlying condition, and nutritional support needs. These factors may influence overall outcome in short bowel syndrome. The better nutritional prognosis of patients undergoing repeated resection given similar intestinal remnants may be related in part to enhanced intestinal adaptation.
