Brad Denney, Jorge I de la Torre
Component separation with mesh reinforcement has become the primary modality for complex abdominal wall reconstruction. However, many fundamental questions remain unanswered, such as whether underlay versus overlay mesh placement is superior, and what is the best means of suture fixation technique for mesh placement? This study presents the senior author's technique for onlay biologic mesh placement with multipoint suture fixation in combination with component separation and its subsequent low recurrence rates...

BACKGROUND: Candidates for multivisceral transplantation present with complex defects often beyond traditional reconstructive options. In this study, the authors describe a dissection technique for a total abdominal wall vascularized composite flap. In addition, the authors suggest a classification system for complex abdominal wall defects. METHODS: Forty fresh, cadaveric hemiabdomens were dissected, with care taken to preserve the iliofemoral, deep circumflex iliac, superficial circumflex iliac, deep inferior epigastric, and superficial inferior epigastric arteries and corresponding veins...

The article presents a case report of a patient with an intramural gastric hematoma. Diagnostic examinations were suggestive of a suspected gastrointestinal stromal tumor Normal image was observed in gastroscopic examination while abdominal CT scan revealed a nodular lesion along the greater curvature of the stomach extending from the posterior wall and adjoining the pancreas and the spleen. The patient was qualified for surgical treatment. Laparotomy was performed followed by total gastric resection and Roux-en-Y reconstruction of the gastrointestinal tract...

Criteria for rupture prediction of Abdominal Aortic Aneurysm (AAA) are based only on the diameter of AAA. This method does not consider complex hemodynamic forces exerted on AAA wall. The methodology used in our study combines Computer-Aided Design (CAD) with Computational Fluid Dynamics (CFD). Three-dimensional vascular structures reconstructions were based on Computed Tomography (CT) images and CAD. CFD theory was used for mathematical modeling and simulations. In this way, dynamic behavior of blood flow in bounded three-dimensional space was described...

BACKGROUND: An increasing number of patients have large or complex abdominal wall defects. Component separation technique (CST) is a very effective method for reconstructing complex midline abdominal wall defects in a manner that restores innervated muscle function without excessive tension. Our goal is to show our results by a modified CST for treating large ventral hernias. MATERIALS AND METHODS: A total of 351 patients with complex ventral hernias have been treated over a 10-year period...

Jejunostomy, which requires the fixation of the jejunum to the abdominal wall, is commonly used as an enteral feeding access after esophagectomy. However, this procedure sometimes causes severe complications, such as mechanical bowel obstruction. In 2009, we developed a modified approach to insert an enteral feeding tube through the reconstructed gastric tube using the round ligament of the liver. The aim of this study is to investigate the usefulness of this approach as compared to the approach through jejunostomy...

INTRODUCTION: The eventrated, giant abdominal wall hernias represent a considerable challenge in our practice. Presently, preoperative evaluation of the musculo-aponeurotic elements of the abdominal wall by CT imaging is not part of routine planning of surgery. AIM: Evaluation of the abdominal wall hernia progression in time. Moreover, follow up the changes of the abdominal wall structures following series of intraabdominal surgeries. METHOD: Abdominal CT imaging were performed on the 1st, 3rd, 6th, 12th, 18th, and 24th postoperative months after the primary series of surgeries in the cases of 12 patients, whose reconstructive surgeries were not possible...

Abdominal wall reconstruction is a rapidly evolving area of surgical interest. Due to the increase in prevalence and size of ventral hernias and the high recurrence rates, the academic community has become motivated to find the best reconstruction techniques. Whilst interrogating the abdominal wall reconstruction literature, we discovered an inconsistency in hernia nomenclature that must be addressed. The terms used to describe the anatomical planes of mesh implantation 'inlay', 'sublay' and 'underlay' are misinterpreted throughout...

Stoma prolapse represents one of the most common late complications, occurring in 1-16%. Final rate depends on systematic follow up of the patient and the primary technique. A 49-year-old male patient presented in the Emergency Department, complaining about stoma prolapse, pain and stoma care difficulties. On admission, his colostomy protruded ~20 cm from the skin. The symptoms were local pain and psychological stress. The prolapse was repaired successfully with a simple revision procedure under local anesthesia, by resecting the prolapsed part of the bowel and reconstruction of stoma...

Abdominal muscles, such as the oblique- and transverse muscles, find their blood supply from multiple segmental pedicles from the iliac artery. Besides its superior vascularization, its release is simple, leaving two abdominal muscles for securing abdominal wall strength. The release of the muscle and coverage of the graft requires partial muscle mobilization and is a minor reconstruction, but extension of the mobilization cranially enables coverage of larger defects. We present a case of an infected vascular graft in the groin successfully preserved through coverage with an external oblique muscle flap...

BACKGROUND: Obesity and higher body mass index may be associated with higher rates of wound healing complications and hernia recurrence rates following complex abdominal wall reconstruction. The authors hypothesized that higher body mass indexes result in higher rates of postoperative wound healing complications but similar rates of hernia recurrence in abdominal wall reconstruction patients. METHODS: The authors included 511 consecutive patients who underwent abdominal wall reconstruction with underlay mesh...

BACKGROUND: The use of left ventricular assist devices (LVADs) to treat advanced cardiac heart failure is constantly increasing, although this device leads to high risk for gastrointestinal bleeding. METHODS: Using in-silico flow analysis, we quantified hemodynamic alterations due to continuous-flow LVAD (HeartWare, Inc., Framingham, MA) in the celiac trunk and major branches of the abdominal aorta, and then explored the relationship between wall shear stress (WSS) and celiac trunk orientation...

Desmoid tumor is a rare monoclonal fibroblast proliferation that is regarded as benign. The clinical management of desmoid tumors is very complex and requires a multidisciplinary approach because of the unpredictable disease course. For those cases localized in the anterior abdominal wall, symptomatic and unresponsive to medical treatment, radical resection and reconstruction with a prosthetic device are indicated. We present here a case of desmoid fibromatosis of the left anterolateral abdominal wall with a marked increase of the mass that required a large excision followed by reconstruction with biological matrix...

BACKGROUND: Patients with symptomatic umbilical, trocar, and/or epigastric hernias and concomitant rectus abdominis diastasis represent a growing clinical problem. The optimal management of this complex hernia situation is the subject of debate in the literature. This paper reports the early results of an innovative surgical technique aimed at managing this hernia situation. METHODS: Endoscopic-assisted linea alba reconstruction (ELAR) with mesh augmentation is a surgical technique long known in the literature for its good outcome for incisional hernia repair (myofascial release, overlapping herniorrhaphy, Gibson's operation, shoelace repair, anterior rectus sheath repair, dynamic patch plasty) via a small access route...

Hemodynamic in abdominal aorta bifurcation was investigated in a real case using computational fluid dynamics. A Newtonian and non-Newtonian (Walburn-Schneck) viscosity models were compared. The geometrical model was obtained by 3D reconstruction from CT-scan and hemodynamic parameters obtained by laser-Doppler. Blood was assumed incompressible fluid, laminar flow in transient regime and rigid vessel wall. Finite volume-based was used to study the velocity, pressure, wall shear stress (WSS) and viscosity throughout cardiac cycle...

In vivo behavior of hydrogel-based biomaterials is very important for rational design of hydrogels for various biomedical applications. Herein, we developed a facile method for in situ fabrication of radiopaque hydrogel. An iodinated functional diblock copolymer of poly(ethylene glycol) and aliphatic polyester was first synthesized by coupling the hydroxyl end of the diblock copolymer with 2,3,5-triiodobenzoic acid (TIB) and then a radiopaque thermoreversible hydrogel was obtained by mixing it with the virgin diblock copolymer...

BACKGROUND: Tissue expanders (TEs) can be used to assist primary closure of complicated hernias and large abdominal wall defects. However, there is no consensus regarding the optimal technique, use, or associated risk of TE in abdominal wall reconstruction. METHODS: A systematic search of PubMed and Embase databases was conducted to identify articles reporting abdominal wall reconstruction with TE techniques. English articles published between 1980 and 2016 were included on the basis of the following inclusion criteria: two-stage TE surgical technique, >3 cases, reporting of postoperative complications, hernia recurrence, and patient-based clinical data...
