Background: Incisional hernia is a common complication after operation and could be alleviated by laparoscopic incisional hernia repair. This study aimed to explore risk factors for prolonged operative time and hospitalization of patients undergoing laparoscopic incisional hernia repair.

Methods: 82 patients who received laparoscopic incisional hernia repair between January 2010 and June 2015 were divided into 2 groups including duration of surgery<120 min group and >120 min group, or length of stay<5 day group and >5 day group. Risk factors such as the age, gender, BMI, duration of hernia, comorbidities, multiple hernias, recurrent hernias, hernia size, mesh size, duration of surgery, and complication were analysed.

Results: Complication rate was 19.51%. The proportions of multiple hernias, recurrent hernias, hernia size>8 cm and mesh size>300 cm² of duration of surgery>120 min group were higher than those of duration of surgery<120 min group. Multiple hernias, recurrent hernias, and mesh size>300 cm² were risk factors for prolonged operative time. The proportions of age>55 years, multiple hernias, recurrent hernias, hernia size>8 cm, mesh size>300 cm² and duration of surgery>120 min of length of stay>5 day group were higher than those of length of stay<5 day group. Advanced age, mesh size>300 cm² and prolonged operative time were risk factors for prolonged hospitalization.

Conclusion: Patients with multiple, larger and recurrent hernias have longer operative time and hospitalization during laparoscopic incisional hernia repair, and should be paid more attention.
