Abstract
Background: Laparoscopic incisional hernia repair is increasingly performed worldwide and expected to be superior to conventional open repair regarding hospital stay and quality of life (QoL). The INCisional Hernia-Trial was designed to test this hypothesis. Methods: A multicenter parallel randomized controlled open-label trial with a superiority design was conducted in six hospitals in the Netherlands. Patients with primary or recurrent incisional hernias were randomized by computer-guided block-randomization to undergo either conventional open or laparoscopic repair. Primary endpoint was postoperative length of hospital stay in days. Secondary endpoints included QoL, complications, and recurrences. Patients were followed up for at least 5 years. Results: Hundred-and-two patients were recruited and randomized. In total, 88 patients underwent surgery and were included in the intention-to-treat analysis (44 in the open group, 44 in the laparoscopic group). Mean age was 59.5 years, gender division was equal, and BMI was 28.8 kg/m. The trial was concluded early for futility after an unplanned interim analysis, which showed that the hypothesis needed to be rejected. There was no difference in primary outcome: length of hospital stay was 3 (range 1–36) days in the open group and 3 (range 1–12) days in the laparoscopic group (p = 0.481). There were no significant between-group differences in QoL questionnaires on the short and long term. Satisfaction was impaired in the open group. Overall recurrence rate was 19%, of which 16% in the open and 23% in the laparoscopic group (p = 0.25) at a mean follow-up of 6.6 years. Conclusions: In a randomized controlled trial, short- and long-term outcomes after laparoscopic incisional hernia repair were not superior to open surgery. The persisting high recurrence rates, reduced QoL, and suboptimal satisfaction warrant the need for patient’s expectation management in the preoperative process and individualized surgical management.
