Abstract Aim Abdominal wall reconstruction in high-risk and contaminated cases remains a challenging surgical dilemma. We report long-term clinical outcomes for a rifampin/minocycline-coated acellular dermal graft (XenMatrix™ AB) in complex abdominal wall reconstruction for patients with a prior open abdomen or contaminated wounds. Material and Methods Patients undergoing abdominal wall reconstruction at our institution at high risk for surgical site occurrence and reconstructed with XenMatrix™ AB with intent-to-treat between 2014 through 2017 were included. Demographics, operative characteristics, and outcomes were collected. Primary outcome was hernia recurrence. Secondary outcomes included length of stay, surgical site occurrence, readmission, morbidity, and mortality. Results Twenty-two patients underwent abdominal wall reconstruction using XenMatrix™ AB during the study period. Two patients died while inpatient from progression of their comorbid diseases and were excluded. Sixty percent of patients had an open abdomen at time of repair. All patients were Modified VHWG class 2 or 3. There was a total of four 30-day infectious complications including superficial cellulitis/fat necrosis (15%) and one intraperitoneal abscess (5%). No patients required re-operation or graft excision. Median clinical follow-up was 35.1 months with a mean of 32.2 +/- 16.5 months. Two asymptomatic recurrences and one symptomatic recurrence were noted during this period. Follow-up was extended by phone interview which identified no additional recurrences at a median of 45.5 and mean of 50.5 +/-12.7 months. Conclusions We present long-term outcomes for patients with high-risk and contaminated wounds who underwent abdominal wall reconstruction reinforced with XenMatrix™ AB to achieve early, permanent abdominal closure. Acceptable outcomes were noted.

Objective: Due to the similarities of glabrous skin, the plantar region is an excellent donor area for covering complex palmar–plantar wounds. However, taking grafts from the plantar area often results in significant morbidity at the donor site or non-integration of the graft due to the greater thickness of the plantar corneal layer. Method: This is a prospective case series including patients with burns or wounds who have been treated with a dermal graft using the bilaminar ‘trapdoor’ technique. This procedure is used to remove a thin graft from the deep plantar dermis after the partial elevation of the first layer including the entire epidermis and superficial part of the dermis. Results: At the donor area in the four patients in this case series, we observed healing at around 10 days, and absence of hypertrophic scar in all patients. There was complete re-epithelialisation between two and three weeks from the periphery to the centre of the deep dermal graft, and from the glandular epithelium transferred with the graft. During the follow-up, patients presented aesthetic and functional features of glabrous and amelanotic skin, with similar resistance to those of the adjacent areas of the wound in the palmar–plantar region. Conclusion: This technique has some advantages, such as less surgical time, minimal morbidity in the plantar donor area, easy integration of the grafts, and maintenance of the functional and aesthetic properties of glabrous skin both in the plantar donor area and in the palmar–plantar recipient region. Declaration of interest: The authors have no conflicts of interest to declare.

(1) Background: Pelvic organ prolapse (POP) is common among post-menopausal women affecting more than 25% in their lifetime—with 11% having a lifetime risk of undergoing an operation for a POP. In April 2019, the Food and Drug Administration (FDA) took surgical mesh for transvaginal use off the market due to safety and effectiveness concerns. This leaves colporrhaphy or colporrhaphy with bio-graft options for a POP surgical repair. (2) Case: In this report, we look at a case with anterior mesh erosion complicated by poor wound healing secondary to heavy tobacco use and how it was successfully removed and augmented with a Coloplast axis allograft dermis biological graft secured with an Anchorsure sacrospinous ligament/arcus tendineus fascia pelvis fixation device and prolene suture. (3) Results: After failing two prior surgeries to rectify the mesh erosion, a final procedure was performed using a biologic dermal graft and a double-layer closure to aid in protecting and increasing the integrity of the tissue. (4) Conclusions: Collectively, the patient and her surgeries highlight the difficult nature of complete mesh removal and how tobacco use can significantly affect the proper healing of surgical sites. The number of surgeries necessary to address the patient’s chief complaint and the resolution of her symptoms with the biologic graft supports the challenges one faces with mesh removal and poor wound healing secondary to tobacco use. This case illustrates that complicated transvaginal mesh erosion should initially be augmented with a biologic dermal graft secured via sacrospinous ligament/arcus tendineus fascia pelvis fixation and double-layer closure and not only if visible mesh removal alone fails.

No patients required reoperation or graft excision. Median clinical follow-up was 38.2 months with a mean of 35.2 +/− 18.5 months. Two asymptomatic recurrences and one symptomatic recurrence were noted during this period with one planning for elective repair of an eventration. Follow-up was extended by phone interview which identified no additional recurrences at a median of 45.5 and mean of 50.5 +/−12.7 months. Conclusion We present long-term outcomes for patients with high-risk and contaminated wounds who underwent abdominal wall reconstruction reinforced with XenMatrix™ AB to achieve early, permanent abdominal closure.

Abstract Background: To explore the effects of autologous free dermal graft combined with free myocutaneous flap on bronchopleural fistula with empyema. Methods: Two patients with refractory empyema and bronchopleural fistula were treated with autologous free dermal graft combined with free myocutaneous flap. The free dermal graft was harvested from the skin around the incision and the fistula was sutured intermittently. The lateral femoral myocutaneous flap was selected as the free flap. Using microsurgery techniques, the descending branch of the lateral femoral circumflex artery and the thoracodorsal blood vessel were anastomosed intermittently to maintain the blood supply of the myocutaneous flap. After surgery, the empyema, air leakage, and the survival of the myocutaneous flap were observed. Results: No necrosis of the myocutaneous flap was observed after surgery. There was no disease recurrence after follow-up for seven and six months, respectively. Re-examination of the chest computed tomography or magnetic resonance imaging indicated that the empyema residual cavity had disappeared. Conclusion: Autologous free dermal graft combined with free lateral femoral myocutaneous flap transplantation is effective in the treatment of patients with bronchopleural fistula with refractory chronic empyema, with satisfactory clinical effects.

A 74-years-old patient, without comorbidity, underwent malleable penile prosthesis (MPP) implantation in 2007. In 2015, after a perineal trauma, he experienced stress urinary incontinence, medial extrusion of the left prosthetic cylinder and an urethrocavernous fistula. The cylinder was removed and an artificial urinary sphincter (AUS) implanted, together with a three-component inflatable penile prosthesis (IPP). The left corpus cavernosum (CC) was significantly shorter than the right one due to fibrosis. After 8 months, partial lateral extrusion of the right prosthetic cylinder prompted a replacement with a shorter extensor. Six months after, a new diastasis of the ruptured area occurred due to a further CC shortening. The extensor was removed and the cylinder shortened, with a dermal graft applied to the area. Long-term patient satisfaction was high.

Background: The retear rate after rotator cuff repair remains unacceptably high. Various biological engineered scaffolds have been proposed to reduce the retear rate. We have developed a double rip-stop repair with medial row knot (DRSK) technique to enhance suture-tendon strength and a novel engineered tendon-fibrocartilage-bone composite (TFBC) for rotator cuff repair. Hypothesis: DRSK rotator cuff repair augmented with TFBC will have better biomechanical properties than that of DRSK repair with an acellular dermal graft (DG). Study Design: Controlled laboratory study. Methods: Fresh-frozen canine shoulders (n = 30) and knees (n = 10) were used. TFBCs were harvested from the patellar tendon–tibia complex and prepared for rotator cuff repair. The infraspinatus tendon was sharply detached from its bony attachment and randomly assigned to the (1) control group: DRSK repair alone, (2) TFBC group: DRSK repair with TFBC, and (3) DG group: DRSK repair with DG. All specimens were tested to failure, and videos were recorded. The footprint area, tendon thickness, load to create 3-mm gap formation, failure load, failure modes, and stiffness were recorded and compared. Data were recorded as mean ± SD. Results: The mean load to create a 3-mm gap in both the control group (206.8 ± 55.7 N) and TFBC group (208.9 ± 39.1 N) was significantly higher than that in the DG group (157.7 ± 52.3 N) ( P < .05 for all). The failure load of the control group (275.7 ± 75.0 N) and TFBC group (275.2 ± 52.5 N) was significantly higher compared with the DG group (201.5 ± 49.7 N) ( P < .05 for both comparisons). The stiffness of the control group (26.4 ± 4.7 N/mm) was significantly higher than of the TFBC group (20.4 ± 4.4 N/mm) and the DG group (21.1 ± 4.8 N/mm) ( P < .05 for both comparisons). Conclusion: TFBC augmentation showed superior biomechanical performance to DG augmentation in rotator cuff tears repaired using the DRSK technique, while there was no difference between the TFBC and control groups. Clinical Relevance: TFBC may help to reduce retear or gap formation after rotator cuff repair using the DRSK technique.
