Prophylactic mesh placement is associated with an 85% postoperative incisional hernia risk reduction when compared to primary suture closure in at-risk patients undergoing elective, midline laparotomy closure. This technique appears to be safe with comparable complication profiles, barring an increased risk of seroma, especially with the onlay technique, and the possibility for an increased risk of chronic pain. Despite this verification, evidence from large domestic trials that sufficiently addresses major knowledge gaps is simply lacking.

Use of CCDSSs increases the proportion of surgical patients who were prescribed adequate prophylaxis for VTE and correlates with a reduction in VTE events.

Botulinum toxin injections offer tremendous potential in ventral hernia management by reducing hernia width and lengthening abdominal wall muscles prior to repair. Although further studies are needed, there is a significant opportunity to bridge the knowledge gap in preoperative practice measures for ventral hernia risk reduction.

Introduction: Soft-tissue reconstruction of the scalp has traditionally been challenging in oncologic patients. Invasive tumors can compromise the calvarium, necessitating alloplastic cranioplasty. Titanium mesh is the most common alloplastic material, but concerns of compromise of soft-tissue coverage have introduced hesitancy in utilization. The authors aim to identify prognostic factors associated with free-flap failure in the context of underlying titanium mesh in scalp oncology patients. Methods: A retrospective review (2010–2018) was conducted at a single center examining all patients following oncologic scalp resection who underwent titanium mesh cranioplasty with free-flap reconstruction following surgical excision. Patient demographics, comorbidities, ancillary oncological treatment information were collected. Operative data including flap type, post-operative complications including partial and complete flap failure were collected. Results: A total of 16 patients with 18 concomitant mesh cranioplasty and free-flap reconstructions were identified. The majority of patients were male (68.8%), with an average age of 70.5 years. Free-flap reconstruction included 15 ALT flaps (83.3%), 2 latissimus flaps (11.1%), and one radial forearm flap (5.5%). There were three total flap losses in two patients. Patient demographics and comorbidities were not significant prognostic factors. Additionally, post-operative radiation therapy, ancillary chemotherapy, oncological histology, tumor recurrence, and flap type were not found to be significant. Pre-operative radiotherapy was significantly associated with flap failure (P < 0.05). Conclusion: Pre-operative radiotherapy may pose a significant risk for free-flap failure in oncologic patients undergoing scalp reconstruction following mesh cranioplasty. Awareness of associated risk factors ensures better pre-operative counseling and success of these reconstructive modalities and timing of pre-adjuvant treatment.

Addition of ffPRP improves initial ASC adherence while a single administration of either fresh or flash frozen PRP without additional cell manipulation significantly augments subsequent ASC proliferation. The potential for spontaneous osteogenic differentiation upon PRP exposure invokes the need for additional molecular studies of PRP activity prior to further expansion to clinical applications.

Incisional hernia (IH) is a challenging, potentially morbid condition. This study evaluates recent trends in hospital encounters associated with IH care in the United States. Using Nationwide Inpatient Sample databases from 2007 to 2011, annual estimates of IH-related hospital discharges, charges, and serious adverse events were identified. Significance in observed trends was tested using regression modeling. From 2007 to 2011, there were 583,054 hospital discharges associated with a diagnosis of IH. 81.1 per cent had a concurrent procedure for IH repair. The average discharge included a female patient (63.2%), 59.8 years of age, with either Medicare (45.3%) or Private insurance (38.3%) as the anticipated primary payer. Comparing 2007 to 2011, significant increases in IH discharges (12%; 2007 = 109,702 vs 2011 = 123,034, P = 0.009) and IH repairs (10%; 2007 = 90,588 vs 2011 = 99,622, P < 0.001) were observed. This was accompanied by a 37 per cent increase in hospital charges (2007 = $44,587 vs 2011 = $60,968, P < 0.001), resulting in a total healthcare bill of $7.3 billion in 2011. Significant trends toward greater patient age (2007 = 59.7 years vs 2011 = 60.2 years, P < 0.001), higher comorbidity index (2007 = 3.0 vs 2011 = 3.5, P < 0.001), and increased frequency of serious adverse events (2007 = 13.5% vs 2011 = 17.7%, P < 0.001) were noted. Further work is needed to identify interventions to mitigate the risk of IH development.
