BACKGROUND: Transversus abdominis release (TAR) has evolved as an effective approach to complex abdominal wall reconstructions. Although the role of robotics in hernia surgery is rapidly expanding, the benefits of a robotic approach for abdominal wall reconstruction have not been established well. We aimed to compare the impact of the application of robotics to the TAR procedure on the perioperative outcomes when compared to the open TAR repairs. METHODS: Case-matched comparison of patients undergoing robotic TAR (R-TAR) at two specialized hernia centers to a matched historic cohort of open TAR (O-TAR) patients was performed...

BACKGROUND: Hernia meshes exhibit variability in mechanical properties, and their mechanical match to tissue has not been comprehensively studied. We used an innovative imaging model of in vivo strain tracking and ex vivo mechanical analysis to assess effects of mesh properties on repaired abdominal walls in a porcine model. We hypothesized that meshes with dissimilar mechanical properties compared to native tissue would alter abdominal wall mechanics more than better-matched meshes. METHODS: Seven mini-pigs underwent ventral hernia creation and subsequent open repair with one of two heavyweight polypropylene meshes...

BACKGROUND: Transversus abdominis release (TAR) is a safe, effective strategy to repair complex ventral incisional hernia (VIH); however, open TAR (o-TAR) often necessitates prolonged hospitalization. Robot-assisted TAR (r-TAR) may benefit short-term outcomes and shorten convalescence. This study compares 90-day outcomes of o-TAR and r-TAR for VIH repair. METHODS: A single-center, retrospective review of patients who underwent o-TAR or r-TAR for VIH from 2015 to 2016 was conducted...

INTRODUCTION: High-tension electricity can cause devastating injuries that may result in abdominal wall loss, visceral damage, and sometimes major threat to life. The visceral organ may be exposed after debridement and require flap cover, but the tensile strength of abdominal wall may be lack even if flap transplanted. METHODS: From April 2007 through May 2015, 5 patients with severe abdominal electrical injury were treated at our hospital. Exploratory laparotomy was performed based on their clinical manifestations and debridement findings of abdominal wall at early stage, and decision regarding technique for reconstruction of abdominal wall was based on an assessment of the location and extent of the defect...

INTRODUCTION: The optimal management of the open abdomen (OA) after liver transplantation (LT) is unclear. The negative pressure wound therapy (NPWT) has been shown to be safe and can increase the chance for early fascial closure in trauma or septic patients. However, little data are available on the specific setting of LT. We aimed to report our experience of OA after LT, marked by the recent use of NPWT. METHODS: All patients with postponed wall closure after LT, from 2002 to 2014, in a single institution were included and retrospectively analyzed...

BACKGROUND: The use of acellular dermal matrices (ABDM) has become more common for breast reconstruction to improve postoperative outcomes. We evaluated the efficacy of breast reconstruction by the application of human ABDM in a sheep model. METHODS: The sheep in group I (GI) (N = 4) underwent the following procedures on the right side: (1) breast reconstruction using human ABDM after total mastectomy, (2) human ABDM under the skin, near the breast area and on the left side, (3) fat injection and human ABDM after partial mastectomy, and (4) replacement of ABDM in the abdominal wall far from the breast...

BACKGROUND: In large incisional hernias and after laparostoma midline closure may be impossible. A novel abdominal wall expander system (AWEX) is proposed and evaluated. METHODS: In patients with large incisional hernias and laparostoma where primary midline closure was impossible, AWEX was used. Patients undergoing abdominal wall reconstruction using AWEX between May 2012 and December 2015 were included. Intraoperative the abdominal wall was stretched by attaching the midline fascia borders to a retraction system under tension for 30 minutes...

BACKGROUND: Mesh infection after abdominal hernia repair is a devastating complication that affects general and plastic surgeons alike. The purpose of this study was 3-fold: (1) to determine current evidence for treatment of infected abdominal wall mesh via systematic review of literature, (2) to analyze our single-institution experience with treatment of infected mesh patients, and (3) to establish a framework for how to approach this complex clinical problem. METHODS: Literature search was performed using the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, followed by single-institution retrospective analysis of infected mesh patients...

PURPOSE: Electrospun meshes may be considered as substitutes to textile polypropylene implants. We compared the host response and biomechanical properties of the rat abdominal wall following reinforcement with either polycaprolactone (PCL) modified with ureidopyrimidinone-motifs (UPy) or polypropylene mesh. METHODS: First we measured the response to cyclic uniaxial load within the physiological range both dry (room temperature) and wet (body temperature). 36 rats underwent primary repair of a full-thickness abdominal wall defect with a polypropylene suture (native tissue repair), or reinforced with either UPy-PCL or ultra-light weight polypropylene mesh (n = 12/group)...

BACKGROUND: An incisional hernia in a case of antethoracic pedicled jejunal flap esophageal reconstruction after esophagectomy is a very rare occurrence, and this hernia was distinctive in that the reconstructed jejunum had passed through the hernial orifice; a standard surgical treatment for such a presentation has not been established. Herein, we describe a case of repair using mesh prosthesis for an atypical and distinctive incisional hernia after antethoracic pedicled jejunal flap esophageal reconstruction...

The case of a giant thoracic desmoid tumour in a 44-year-old woman, who presented two years following a breast reconstruction with a latissimus dorsi (LD) flap and implant, is reported. Clinical findings included a rapidly growing, painless mass. Computed tomography (CT) suggested skin and intercostal soft tissue invasion. The tumour was resected en bloc with the LD muscle, implant capsule and underlying rib segments. The resultant thoracic and abdominal wall defects were reconstructed with Dualmesh® and polypropylene meshes respectively...

BACKGROUND: In recent years, the deep inferior epigastric perforator (DIEP) flap has become the workhorse flap for autologous breast reconstruction. Despite increased reports on DIEP flaps, umbilical complications have not been previously studied. The aesthetics of the umbilicus dictates the beauty of the abdomen, and it is critical for plastic surgeons to minimize the scarring of the umbilicus. In this study, we retrospectively reviewed patients who underwent DIEP flaps to determine the predictors of umbilical complications, and created a classification system of these wounds...

Extraskeletal osteosarcomas (OSs) are highly malignant soft tissue tumours associated with a poor prognosis. Only a few records of these rare aggressive neoplasms have been reported in the literature.We describe the case of a 49-year-old man, who presented to our tertiary care centre with a painful isolated lump around the umbilicus. After surgical biopsy, imaging and subsequent pathological analysis, the swelling was diagnosed to be a localised extraskeletal OS. He received previous radiation as treatment for testicular seminoma 40 years ago, which has been in remission ever since...

INTRODUCTION: In vascular surgery the crossover iliofemoral bypass grafting is a well-known surgical technique. In general surgery the repair of an abdominal defect using a Polypropylene mesh is also a standard procedure. A particular technique is defined by the performance of these 2 separate procedures inside a single operation in which the crossover arterial graft is directed from the retroperitoneal space toward the contra-lateral femoral bifurcation through a Polypropylene mesh which closes the musculoaponeurotic layers of the abdominal wall...

Gastric duplication is an uncommon condition in adults representing only 4-8% of all gastrointestinal duplications. It develops as a cystic growth within the thick gastric wall that is surrounded by a layer of smooth muscle and lined with gastric mucosa. It is usually asymptomatic but may present with nonspecific abdominal symptoms as well as cyst-related complications such as gastrointestinal (GI) bleeding, ulceration and even pancreatitis. They are difficult to distinguish from other gastric submucosal lesions and may also mimic a gastrointestinal tumor (GIST) or mucinous cyst of the pancreas...

BACKGROUND/AIM: The pedicled transverse rectus abdominis myocutaneous (TRAM) flap remains widely used as a breast reconstruction technique. The bipedicled TRAM flap is not as preferable as it was formerly, mainly because of its donor site complications. However, in a number of situations, a bipedicled TRAM flap may be the only alternative. Therefore, a three-layer primary closure technique used with bipedicled TRAM flap breast reconstructions that can avoid donor site complications without using a mesh is presented...

Hernia meshes significantly reduce the recurrence rates in hernia repair. It is known that they affect the abdominal wall postimplantation, yet the understanding of in vivo mechanics in the mesh placement area is lacking. We established a single C-arm biplane fluoroscopic system to study strains at the interface between the mesh and repaired abdominal tissues. We aimed to validate this system for future porcine hernia repair studies. Custom matlab programs were written to correct for pincushion distortion, and direct linear transformation (DLT) reconstructed objects in 3D...

BACKGROUND: Hepatic portal venous gas (HPVG) is a rare imaging finding in children. It can be an important manifestation of severe diseases such as necrotizing enterocolitis (NEC) in neonates or bowel wall rupture in older children. However, there are many other diseases presenting with HPVG that do not necessarily require a surgical intervention. CASE REPORT: In the period between 2011-2015, there were 12 cases of HPVG in children aged up to 24 months in our hospital...

INTRODUCTION: Some surgeons consider a high body mass index (BMI) or important abdominal fat excess as contraindications for breast reconstruction with free deep inferior epigastric perforator (DIEP) flap. This study aimed to identify factors associated with post-operative complications by using this type of flap, with an emphasis on BMI and abdominal subcutaneous fat thickness. METHODS: A retrospective chart review of 105 consecutive patients who underwent DIEP flap breast reconstruction at our institution was performed to assess post-operative complications...
