The repair of complex abdominal wall defects in contaminated fields often presents a dilemma for general surgeons. Synthetic mesh, although strong, may lead to chronic infection or even visceral erosion. Leaving the abdomen open presents challenges for ward management and delays definitive care, as well as allowing the musculature to retract over time. Numerous biological mesh alternatives have arisen over the previous decade, which may make primary closure in this setting a practical alternative, although durability may prove the downside. Here we present our local experience with PermacolTM mesh (Porcine Acellular Dermal Matrix - PADM; Covidien, Mansfield, MA) in four challenging cases and discuss the role this relatively new mesh may have for these and other applications.

Background: Patients with end-stage kidney disease often prefer home-based dialysis due to higher self-efficacy, which relates to improved medical treatment adherence. Kidney transplantation (KT) success depends on adhering to immunosuppressive medication post-transplant.
Objectives: To investigate whether adherence post-kidney transplantation (KT) and patients' attitudes toward immunosuppression were influenced by their prior dialysis type modality.

Background: Acute pancreatitis (AP) is a prevalent pathological condition of abdomen characterized by sudden onset, high incidence and complex progression. Timely assessment of AP severity is crucial for informing intervention decisions so as to delay deterioration and reduce mortality rates. Existing AP-related scoring systems can only assess current condition of patients and utilize only a single type of clinical data, which is of great limitation.

Purpose: To report a case series on using a novel semi-branch feature in custom-made stent-grafts in the endovascular treatment of complex aortic aneurysms and summarize the contemporary usage of this technology.
Case Series: Four patients underwent endovascular aortic aneurysm repair (EVAR) with a custom-made semi-branch stent-graft (Semi-Branch Endovascular Aortic Aneurysm Repair [SBEVAR]). Two male patients, 75- and 76-year-old, were treated due to failed EVAR with late-type Ia endoleak, and the other two, 80- and 55-year-old male patients, due to a juxta-renal aortic abdominal aneurysm (JRAAA).

Division of Vascular and Endovascular Surgery, Beth Israel Deaconess Medical Center, Boston, MA. Electronic address:
Objective: As aneurysmal disease is progressive, proximal disease progression and para-anastomotic aneurysms are complications experienced after open infrarenal abdominal aortic aneurysm repair (AAA). As such, fenestrated or branched endovascular repair (F/BEVAR) may be indicated in these patients. Data describing fenestrated endovascular aneurysm repair after prior open repair are limited to institutional databases.
