['Laparoscopic ventral hernia repair (LVHR) is associated with shorter hospitalization and lower complication rates compared to open ventral hernia repair. We sought to determine if hernia-related factors, such as defect size and re-operative status correlate with postoperative complications, operative times and length of stay (LOS).', 'The study is a retrospective review of 30-day perioperative outcomes following LVHR in 91 patients who underwent surgery at a single institution from August 2009 through June 2012. A single surgeon performed all procedures.', 'Indications for surgery were recurrent incisional hernia in 33\xa0% of patients and primary incisional or ventral abdominal hernias in the rest. Coated polyester mesh with an average size of 348\xa0cm(2) (±214; range 113-1,036) was used. Mean operative time was 132\xa0min (±66.1; range 53-412). The mean LOS was 4.0\xa0days (±3.5; range 1-22). Complications occurred in 13 patients for overall morbidity of 16.5\xa0% and no mortality. There was one recurrence in 30\xa0days (1.1\xa0%). Patients who had a surgery >120\xa0min or a LOS >1\xa0day were statistically more likely to have multiple hernias, larger defect sizes (>40\xa0cm(2)), larger mesh sizes (>300\xa0cm(2)) or a history of recurrent hernia (P\xa0<\xa00.05). No other clinical or demographic variable evaluated in this study correlated with operative time or LOS.'] Does laparoscopic hernia complexity predict operative time and length of stay?
