AIM: To identify variables that predict in-hospital length of stay (LOS) after laparoscopic ventral hernia repair (LVHR). METHODS: Univariate analysis of patient and intraoperative variables was conducted on an operating room database of LVHRs performed from April 2001 to April 2009. Analysis was performed using either chi-square or linear trend analysis, as appropriate. A multivariate logistic regression model was created manually, to determine independent variables that predict LOS. p Value <0.05 was considered significant. RESULTS: A total of 221 patients, with mean age of 56 years (range 25-88 years) underwent LVHR, for a total of 121 incisional and 100 primary ventral hernias. Of patients, 40% had incarcerated hernias and 25% had complex hernias (defined as multiple points of weakness on the anterior abdominal wall). The overall conversion rate to open operation was 6%. Mean LOS was 1.54 days (range 0-22 days). Eighty-six patients (39%) were discharged on the day of the procedure. Variables associated with significantly longer LOS on univariate analysis were incisional hernia (p = 0.000009), mesh size (p = 0.00007), complex hernia (p = 0.00009), incarcerated hernia (p = 0.0004), patient age (p = 0.0006), need for lysis of adhesions (p = 0.001), and female gender (p = 0.01). American Society of Anesthesiologists (ASA) grade >2, conversion to open procedure, and recurrent hernia were not associated with longer LOS. Four factors were independently associated with significant longer length of stay on multivariate logistic regression analysis (p < 0.05): mesh size (p = 0.00005), incarcerated hernia (p = 0.002), patient age (p = 0.018), and complex hernia (p = 0.035). CONCLUSIONS: Mesh size, incarcerated hernia, patient age, and complex hernia predict longer length of stay after laparoscopic ventral hernia repair.
