How-we-do-it: the repair of postoperative ventral hernias after a Mercedes abdominal incision.

PURPOSE: To describe the abdominal wall reconstruction technique with an Ultrapro mesh and outcome for the repair of postoperative ventral hernias after the use of a Mercedes incision during the initial abdominal operation. METHOD: A retrospective review of all the patients undergoing elective postoperative ventral hernia repair between 2013 and 2019. The cohort of these patients that had an initial Mercedes incision was used for this study. RESULTS: Fourteen patients met the criteria for this study. Thirteen of the patients were transplant patients (10 liver transplant and 3 combined pancreas and kidney transplant), and one patient was after a hepatectomy. Fifty-seven percent of these hernias were multiple defects. All the patients underwent the same repair of a modified Rives-Stoppa, transversus abdominis release, and a bilateral transverse plication. A partially absorbable Ultrapro mesh was used for all the patients, with two of the patients needing an additional Symbotex mesh in order to bridge a portion of the posterior fascia. There were 6 minor early postoperative complications (hematoma, superficial wound infection, and seroma) that did not require reoperation. Two patients were readmitted for observation of a wound hematoma, and two patients (14.2%) had recurrence during the follow-up period. The average length of hospitalization was 5.6 days. CONCLUSION: This technique, with the use of an Ultrapro mesh, was found to be safe and effective for the repair of a postoperative ventral hernia due to an initial Mercedes incision.
