Short-term complications of wide-lumen stapled anastomosis after ileocolic resection for Crohn's disease: who is at risk?

ABSTRACT

AIM: There is growing evidence that stapled anastomoses are similarly effective compared to hand-sewn anastomoses in Crohn's patients. This study was designed to assess safety and limitations of wide-lumen stapled ileocolic anastomoses. METHOD: All patients with ileocolic resections for Crohn's disease perfomed between 1998 and 2006 were studied. A stapled anastomosis was constructed whenever possible. Potential risk factors for postoperative complications were recorded, retrospectively. Univariate and multivariate analyses were performed. RESULTS: In 209 out of 220 cases (95%, 132 primary operations) stapled anastomoses were performed. Eleven patients underwent a hand-sewn anastomosis owing to massive bowel dilatation (n = 7) or increased wall thickness (n = 4). There were 10 major (4.5%; surgical 8, medical 2) complications including two anastomotic leaks and one anastomotic bleed (all from stapled anastomoses) and one death not related to the anastomosis. Minor complications occurred in 25 patients. In multivariate analysis, major surgical postoperative complications were significantly associated with a low level of albumin (P = 0.0113) and previous resections for Crohn's disease (P = 0.0144). CONCLUSION: Stapled ileocolic anastomosis was safe in the majority of Crohn's patients. The most important limitation was technical impracticability. A low level of albumin and a history of previous resection increased the risk of postoperative complications.
