BANNURA C, GUILLERMO et al. Impact and risk factors for early reoperations in colorectal surgery. Rev Chil Cir [online]. 2007, vol.59, n.4, pp. 281-286. ISSN 0718-4026. doi: 10.4067/S0718-40262007000400007.
Background: Early reoperations are usually a consequence of serious failures of the original surgical procedure. Aim: To analyze the clinical impact and risk factors for early reoperations in colorectal surgery. Material and methods: Prospective study of 610 patients aged 59 ± 17 years (329 females), subjected to colorectal surgery. The clinical impact was measured using the operative site infection rate (OSI), mean hospital stay (MHS) and operative mortality (OM). The association between reoperation and 17 variables was analyzed using a stepwise regression model. Results: Thirty nine patients (6.4%) were reoperated. The main causes were anastomotic dehiscence in 14 and intestinal perforation in seven. Six patients died (1%), four (10%) subjected and two (0.3%) not subjected to a reoperation (p<0.01). OSI and MHS were significantly higher among reoperated patients. The univariate analysis associated male gender, benign underlying disease, anastomosis type, model of stapler, the height of anastomosis, operative time and preoperative serum albumin with early reoperation. In the multivariate analysis, only male gender and a preoperative serum albumin of less than 3.5 g/dl, remained as significant predictors. Conclusions: Male gender and a low serum albumin are risk factors for early reoperations in colorectal surgery. Reoperations are associated with significant increases in OSI, MHS and OM
