Introduction: The occurrence of postoperative incisional hernia is more frequent after simultaneous pancreas-kidney transplantation compared with other transplanted parenchymal organs. These complications are especially dangerous in this patient population, because they can compromise the survival of the transplanted organ.
Methods: We performed a retrospective review of a series of adult patients with incisional herniae after 23 consecutive simultaneous pancreas-kidney transplantations between January 2004 and June 2010 seeking to identify risk factors. All 23 patients had a body mass index (BMI) of <25. All surgeons used a similar technique, including a median incision with an intraperitoneal approach, and systemic venous and enteric drainage methods and a layered fascial closure. All combined pancreas-kidney transplant recipients received induction with thymoglobulin and maintenance therapy with sirolimus, reduced-dose cyclosporine and corticosteroids.
Results: An incisional hernia repair was performed in 8/23 patients (34.8%). Four reoperations were required in this group (50%), due to hemoperitoneum (n=2), intra-abdominal abscess (n=1), and venous thrombosis (n=1). The mean elapsed time between transplantation and hernioplasty was 24.5 months (range, 8-51). There was no significant difference in age, gender, BMI, dialysis modality, or operative time among affected compared with the other members of the group.
Conclusion: Despite lack of obesity we observed a relatively higher rate of postoperative herniase, possibly owing to the side effects of a thymoglobulin-sirolimus combination.
