About 5%-11% of all abdominal surgery results in incisional hernia. This rate can be even higher among highrisk populations such as transplant patients. Lifetime incidence of incisional hernia following liver transplant is as high as 43% in recent studies. The transplant population is at higher risk for incisional hernia precisely because of their immunosuppressive therapy. Thus, it is imperative to understand the risk factors for incisional hernia in this unique patient population. This article focuses on understanding preoperative, intraoperative, and postoperative risk factors for failure of hernia repair in the transplant population in addition to discussing risk stratification for incisional hernia in this population. Furthermore, we discuss the utility of panniculectomy in abdominal organ transplantation. Additionally, we discuss the value of mesh placement in abdominal wall closure. Finally, we review the concept of vascularized composite allograft as a method for achieving abdominal wall closure for patients who have failed more traditional repairs and who are left with inadequate tissue for successful repair.
Background Emergency open large bowel procedures have higher rates of intraoperative contamination and increased risk of surgical site infection (SSI) than elective colon surgeries. Several wound management strategies have been proposed, such as vacuum-assisted closure (VAC) therapy and delayed primary closure to improve results. The purpose of this study is to evaluate the relationship between wound management technique and SSI and other quality measures. Methods We performed a retrospective review of patients undergoing open emergency colon surgery from January 2017 to December 2018 by our acute care surgery service. The primary outcome measure was incidence of SSI. Secondary outcome measures included length of stay, reoperation, and 30-day readmission. Results A total of 118 patients were included in the study, with a mean age of 62.8 years and mean BMI of 28.8. Overall incidence of SSI was 19.5%. There was no significant difference in incidence of SSI, reoperation, or 30-day readmission when stratifying by wound management technique or procedure type after controlling for confounding variables. Notably, patients managed with VAC therapy had a statistically significant longer average length of stay and higher total postoperative antibiotic days (both P = .001) than other techniques. Discussion We conclude from our data that wound management technique does not seem to influence rate of SSI, but wound management may influence length of stay or antibiotic duration. These findings suggest that there may not be an advantage to alternative methods of wound management in this high-risk population. Further prospective evaluation should be performed to confirm these findings.
Introduction: Existing salvage protocols for infected breast prostheses using negative pressure wound therapy with instillation and dwell (NPWTi-d) require multiple returns to the operating room and prolonged length of stay. We present our expedited salvage protocol and discuss outcomes and associated costs savings. Methods: Using a retrospective review, we identified 25 consecutive patients (27 breasts) with peri-prosthetic breast infection. Nine patients (10 breasts) underwent removal of infected breast prostheses followed by autologous or staged implant-based reconstruction. Sixteen patients (17 breasts) underwent our single application salvage protocol. A cost analysis was performed comparing the two groups, and an economic model was used to project the cost savings associated with using single application NPWTi-d protocol. Results: Fifteen of the 16 patients (94%) who underwent single application NPWTi-d had successful implant salvage. Average duration of NPWTi-d was 2 days, 7 hours, and average length of stay was 4.43 days. Compared to control, patients who received the single application protocol required significantly fewer hospitalizations and office visits. A total savings of $58,275 could have been achieved by using the single application NPWTi-d protocol in the patients who did not undergo NPWTi-d. Conclusions: Single application of NPWTi-d is a simple, safe, and cost-effective technique for salvage of breast prostheses, with 94% success rate, even in immunocompromised patients and severe infection. Compared to previous protocols, ours requires fewer trips to the operating room, shorter length of stay, and more permanent implants placed during salvage. Our protocol is also associated with fewer office visits and fewer returns to the operating room.
