INTRODUCTION: Minimal evidence exists to guide the surgeon on the risk of complications when performing abdominal wall reconstruction (AWR) in the presence of active infection, contamination or enterocutaneous fistula. This study aims to establish the outcomes of contaminated complex AWR. METHODS: Analysis was conducted according to PRISMA guidelines. Systematic search of the MEDLINE, EMBASE and Pubmed databases was performed. Studies reporting exclusively on single-staged repair of contaminated complex AWR were included...

PURPOSE: Lumbar incisional hernias (LIH) are a rare wall defect, whose surgical management is challenging because no recommendation exists. Moreover, LIH are frequently associated with flank bulging which should be taken into account during LIH surgical repair. We aimed to describe a cohort of patients operated on for LIH using a homogeneous surgical technique and to report surgical outcomes. METHODS: The records of all consecutive patients operated on in a specialized surgical center between January 2009 and January 2015 were retrospectively reviewed...

Alternative approaches to reinforce native tissue in reconstructive surgery for pelvic organ prolapse are warranted. Tissue engineering combines the use of a scaffold with the regenerative potential of stem cells and is a promising new concept in urogynecology. Our objective was to evaluate whether a newly developed long-term degradable polycaprolactone scaffold could provide biomechanical reinforcement and function as a scaffold for autologous muscle fiber fragments. We performed a study with three different rat abdominal wall models where the scaffold with or without muscle fiber fragments was placed (1) subcutaneously (minimal load), (2) in a partial defect (partial load), and (3) in a full-thickness defect (heavy load)...

: Background: complex ventral hernia repair is a frequent and challenging topic. Reconstructive techniques are numerous but most of them are unable to achieve the goals of hernioplasty. Posterior component separation with transverses abdominis muscle release (TAR) is a novel approach that offers a solution for complex ventral hernias. METHOD: The posterior rectus sheath is incised and the retrorectus plane is developed. In a modification of the Rives-Stoppa technique, the transversus abdominis is released medial to the linea semilunaris to expose a broad plane that extends from the central tendon of the diaphragm superiorly, to the space of Retzius inferiorly, and laterally to the retro-peritoneum...

Longitudinal studies of vascular diseases often need to establish correspondence between follow-up images, as the diseased regions may change shape over time. In addition, spatial data structures should be taken into account in the statistical analyses to avoid inferential errors. This study investigates the association between hemodynamics and thrombus growth in abdominal aortic aneurysms (AAAs) while emphasizing on the abovementioned methodological issues. Six AAA surfaces and their follow-ups were three-dimensionally reconstructed from computed-tomography images...

PURPOSE: Amplitude based respiratory gating is known to capture the extent of respiratory motion (RM) accurately but results in residual motion in the presence of respiratory hysteresis. In our previous study, we proposed and developed a novel approach to account for respiratory hysteresis by applying the Bouc-Wen (BW) model of hysteresis to external surrogate signals of anterior / posterior motion of the abdomen and chest with respiration. In this work using simulated and clinical SPECT myocardial perfusion imaging (MPI) studies, we investigate the effects of respiratory hysteresis and evaluate the benefit of correcting it using the proposed BW model in comparison with the abdomen signal typically employed clinically...

BACKGROUND: Autologous abdominal tissue transfer is a well-established method of breast reconstruction. The deep inferior epigastric perforator (DIEP) flap has the additional benefit of minimal donor site morbidity as it spares the muscle and fascia. Conventional DIEP flaps may not provide adequate volume in cases where the patient is thin, has midline abdominal scars, and/or has a large volume of tissue to replace. One solution is to use a bipedicled DIEP flap, incorporating all the available abdominal tissue...

INTRODUCTION: Double-layer dermal grafts are used for the management of complicated abdominal wall hernias in obese, high risk patients. The method has not yet been used in case of emergency in septic/dirty environment. CASE REPORT: A 76-year old female patient (BMI 36.7kg/m(2)) was admitted with mechanical bowel obstruction and sepsis caused by a third time recurred, incarcerated and eventrated abdominal wall hernia. During the emergency surgery perforation of the terminal ileum and the ascending colon was detected, along with a feculent peritonitis and extended abdominal wall necrosis...

BACKGROUND: Long-term outcomes data for hernia recurrence rates following abdominal wall reconstruction (AWR) with acellular dermal matrix (ADM) are lacking. The aim of this study was to assess the long-term durability of AWR using ADM. STUDY DESIGN: We studied patients who underwent AWR with ADM at a single center in 2005-2015 with a minimum follow-up of 36 months. Hernia recurrence was the primary outcome and surgical site occurrence (SSO) was a secondary outcome...

Ibrahim Khansa, Jeffrey E Janis
BACKGROUND: In abdominal wall reconstruction, the retrorectus plane offers an ideal location for mesh placement. Mesh fixation in this plane is often achieved using transfascial sutures, which risks entrapping intercostal nerves and causing significant pain, and takes time to place. A novel alternative is the use of sutureless self-adhering mesh. Although the use of this mesh in inguinal hernias has been well described, studies on its use in abdominal wall reconstruction are lacking. METHODS: Consecutive patients who underwent ventral hernia repair with retrorectus mesh were reviewed...

Reconstruction of large abdominal wall defects is challenging. We herein report the successful reconstruction of an extensive abdominal wall defect using a novel combination of flaps after sarcoma resection. A 74-year-old man presented with a dedifferentiated liposarcoma on his abdominal wall. He underwent excision of the tumor, which resulted in an extensive abdominal wall defect. The defect was reconstructed with a pedicled anterolateral thigh flap with an iliotibial tract and a pedicled superficial inferior epigastric artery flap...

BACKGROUND: The optimal strategy for abdominal wall reconstruction in the presence of a stomal-site hernia is unclear. We hypothesized that the rate of ventral hernia recurrence in patients undergoing a combined ventral hernia repair and stomal-site herniorraphy would not differ clinically from the ventral hernia recurrence rate in patients undergoing an isolated ventral hernia repair. We also hypothesized that bridged ventral hernia repairs result in worse outcomes compared to reinforced repairs regardless of stomal hernia...

BACKGROUND: We hypothesized that elderly patients (≥65 years) experience worse outcomes following abdominal wall reconstruction (AWR) for hernia or oncologic resection. METHODS: We included all consecutive patients who underwent complex AWR using acellular dermal matrix (ADM) between 2005 and 2015. Propensity score analysis was performed for risk adjustment in multivariable analysis and for one-to-one matching. The primary outcome was hernia recurrence; the secondary outcomes included surgical site occurrence (SSO) and bulging...

BACKGROUND: Reconstruction of muscle defects remains a challenge. Our work assessed the potential of an engineered construct made of a human acellular collagen matrix (HACM) seeded with porcine mesenchymal stem cells (MSCs) to reconstruct abdominal wall muscle defects in a rodent model. METHODS: This study compared 2 sources of MSCs (bone-marrow, BMSCs, and adipose, ASCs) in vitro and in vivo for parietal defect reconstruction. Cellular viability and growth factor release (VEGF, FGF-Beta, HGF, IGF-1, TGF-Beta) were investigated under normoxic/hypoxic culture conditions...

BACKGROUND AND OBJECTIVES: Radical excisions of the rectum often result in large perineal and intrapelvic defects. Compromised wound healing can delay adjuvant therapies and limit the patient's prognosis. With current treatment, integrity of the abdominal wall may be maintained. The defect geometry is unique and requires extensive volume for reconstruction. This study describes the surgical technique and reports clinical outcomes of fasciocutaneous posterior thigh flaps as preliminary data for this indication...

A man aged 28 years, with neurofibromatosis type 1, presented with abdominal pain and visible right lower chest swelling. He had cutaneous neurofibromas and several café-au-lait spots. CT scan of the chest and abdomen revealed a giant mass most likely originating from the right 7th intercostal nerve, extending downwards into the abdomen causing massive hepatic compression. A Trucut biopsy showed malignant peripheral nerve sheath tumour. Radical surgical resection with wide margins was performed. The chest wall and diaphragm were reconstructed with improvised surgical technique with excellent results...

BACKGROUND: Rectal prolapse is a disorder of the pelvic floor in which the layers of the rectal mucosa protrude outward through the anus. Surgical repair is the mainstay of treatment. Options include intra-abdominal procedures such as rectopexy and perineal procedures such as the Delorme and Altemeier perineal rectosigmoidectomy. Rectal and vaginal prolapse can often coexist. However, to our knowledge, there are no reported cases of rectal prolapse resolved by the repair of a compressive enterocele abutting the anterior rectal wall through a vaginal approach alone...
