Complicated abdominal wall hernias operated emergency through a hernioplasty with mesh. Risk factors for postoperative morbidity.

Abstract

Introduction: Currently, there are no known risk factors for postoperative complications and mortality in patients who are undergoing surgery for a complicated abdominal wall hernia operated emergency through a hernioplasty with mesh. The main objective is to determine the risk factors for presenting a complication during the postoperative period in patients undergoing emergency with a diagnosis of complicated abdominal wall hernia by a hernioplasty with mesh in the Base Hospital Osorno (HBO) between the years 2002 and 2008. 
Material and methods: retrospective cohort study. We selected patients older than 14 years operated by hernial pathology of the registration of surgeries of the Emergency Service at the Hospital Base Osorno (HBO) between the years 2002 and 2008. We excluded those operated without mesh. It was felt the risk, using odds ratio (OR) and its confidence interval of 95%. Software used: Stata 10.0. 
Results: The cohort included 52 patients, median age 64 years (26-85). The 50% (26 patients) were male. The most frequent location hernia was the groin with 23 cases (44.23%). 49 (94.23%) hernias were catalogd as stuck and 3 (5.77%) as being strangled. Operative morbidity 17.31% (9 patients). Median follow-up, 32 (5-90%) months. Only the installation of drainage turned out to be significant (p<0.05 ), this variable was found to have an OR of 4.7 (IC 95%:1,09-20,79). 
Conclusion: In this study, the installation of a drain after to repair an complicated abdominal wall hernia with mesh would act as a risk factor for presenting a complication during the postoperative period.
