Introduction: The repair of subxiphoidal incisional hernia following median sternotomy is technically demanding due to the specific anatomic situation and the lateral distracting forces in this region. Published data are available from retrospective reports with limited number of patients only. The aim of this study was to evaluate the outcome of subxiphoidal hernia repair comparing laparoscopic and open surgical approach. Materials and Methods: This analysis of Herniamed registry data of patients with subxiphoidal incisional hernia following sternotomy for coronary bypass assesses the perioperative and 1 year follow-up outcome of laparoscopic and open repair. Demographic data and perioperative outcomes were stratified by surgical approach (laparoscopic vs. open) and compared as unadjusted analyses using Chi square and Students t-tests. Results: Of 208 patients identified for the analysis 69 patients (33.2%) underwent laparoscopic and 139 (66.8%) patients had open repair. Concerning demographic data (gender, age, BMI, ASA score), risk factors and hernia size there were no significant differences between laparoscopic and open repair group. For intraoperative, postoperative and general complications as well as complication related re-operations no significant differences were seen between the groups. No significant advantage could be stated for laparoscopic repair regarding duration of operation and hospital stay. The recurrence rate at 1 year follow-up was higher in the laparoscopic group (7.2 vs. 2.2%; p = 0.072). No significant differences were reported in the 1 year follow-up evaluation of pain at rest, pain on exertion and pain requiring treatment. Conclusion: The repair of subxiphoidal incisional hernia is safe in both open and laparoscopic technique. With regard to the lower recurrence rate preference can be given to open repair.
