BACKGROUND:  Abdominal wall morbidity following microvascular breast reconstruction continues to be an area of interest due to both functional and aesthetic concerns. Donor-site closure technique has been shown to affect bulge and hernia rates and ranges from primary closure to various uses of mesh. Few studies to date have compared types of mesh. The present study compares BARD polypropylene to bioabsorbable GORE Bio-A (polyglycolic acid/trimethylene carbonate) mesh used as a fascial underlay with primary fascial closure...

Background: We previously reported that good surgical outcomes can be obtained with breast mold made by 3-dimensional printing. However, detailed breast shape is often difficult to create. Accordingly, we aimed to determine whether transplanting a flap and bioabsorbable mold in vivo would yield better results by retaining the flap shape inside the mold during the scar formation period. Methods: Vascularized adipose flaps were elevated in the bilateral inguinal region of male Sprague-Dawley rats (n = 7)...

Prolonged postoperative air leaks are associated with extended periods of postoperative hospitalization, increased hospital costs, and increased incidence of major cardiopulmonary complications. To prevent prolonged air leaks, we used small pieces of polyglycolic acid mesh as a pledget during the stitching of air leak sites. The stitched sites were then covered with mesh and fibrin glue. This novel technique showed the highest airway pressure tolerance in an ex vivo experimental study. There were no incidents of prolonged air leak among the five clinical cases in which this technique was initially applied...

BACKGROUND: Laparoscopic repair remains the gold-standard treatment for paraesophageal hernia (PEH). We analyzed long-term symptomatic outcomes and surgical reintervention rates after primary PEH repair with onlay synthetic bioabsorbable mesh (W. L. Gore & Associates, Inc., Flagstaff, AZ) and examined body mass index (BMI) as a possible risk factor for poor outcomes and for recurrence. METHODS: We queried a prospectively maintained database to identify patients who underwent laparoscopic primary PEH repair with onlay patch of a bioprosthetic absorbable mesh (Bio-A® Gore®) between 05/28/2009 and 12/31/2013...

Severe damage to the ocular surface can result in limbal stem cell (LSC) deficiency, which contributes to loss of corneal clarity, potential vision loss, chronic pain, photophobia, and keratoplasty failure. Human amniotic membrane (AM) is the most effective substrate for LSC transplantation to treat patients with LSC deficiency. However, the widespread use of the AM in the clinic remains a challenge because of the high cost for preserving freshly prepared AM and the weak mechanical strength of lyophilized AM...

Laparoscopic Roux-en-Y gastric bypass is a bariatric operation that is effective for long-term weight loss. Although rare, one serious complication is an internal hernia through Petersen's space, which may result in bowel strangulation. Although the incidence of internal hernia can be reduced through closing the Petersen's defect, it does not eliminate the risk. This case describes a novel and reliable method to close Petersen's defect. We report the case of a 30-year-old female who underwent a laparoscopic Roux-en-Y gastric bypass for the management of morbid obesity...

Recurrence after ventral hernia repair (VHR) remains a significant complication. We sought to identify the technical aspects of VHR associated with recurrence. Patients who underwent open midline VHR between 2006 and 2013 (n = 261) were retrospectively evaluated. Patients with recurrence (Group 1, n = 48) were compared with those without recurrence (Group 2, n = 213). Smoking, diabetes, and body mass index were not different between groups. More patients in Group 1 underwent clean-contaminated, contaminated, or dirty procedures (43...

INTRODUCTION: There continues to be debate regarding the best surgical technique for the treatment of paraesophageal hernias. While laparoscopic and robotic approaches are widely employed around the world, the benefits of mesh use to reinforce hiatal closure are still not well established. The goal of this manuscript is to describe the currently available results with biologic and bioabsorbable meshes for treatment of paraesophageal hernias, particularly with reference to the rate of recurrence...

BACKGROUND: The omission of postoperative chest tube drainage may contribute to early recovery after thoracoscopic major lung resection; however, a validation study is necessary before the dissemination of a selective drain policy. METHODS: A total of 162 patients who underwent thoracoscopic anatomical lung resection for lung tumors were enrolled in this study. Alveolar air leaks were sealed with a combination of bioabsorbable mesh and fibrin glue. The chest tube was removed just after the removal of the tracheal tube in selected patients in whom complete pneumostasis was obtained...

Recently, adipose tissue has been regenerated by combining scaffolds, growth factors, and/or adipose-tissue-derived stromal cells. However, the safety of growth factors and adipose-tissue-derived stromal cells has not been confirmed in cancer patients. We reported the regeneration of adipose tissue in the internal space of a polypropylene mesh containing a collagen sponge (CS), without using any growth factors or cells. We herein explored the formation of adipose tissue, using the bioabsorbable implant containing CS, in rats...

PURPOSE: An intraluminal coronary stent is a metal mesh tube deployed in a stenotic artery during percutaneous coronary intervention (PCI), in order to prevent acute vessel occlusion. The identification of struts location and the definition of the stent shape is relevant for PCI planning and for patient follow-up. The authors present a fully automatic framework for computer-aided detection (CAD) of intracoronary stents in intravascular ultrasound (IVUS) image sequences. The CAD system is able to detect stent struts and estimate the stent shape...

INTRODUCTION: Septorhinoplasty in cleft patients is relatively difficult to perform and the outcomes are often unsatisfactory owing to weakness of the cartilage. Therefore, providing support to the cartilage is necessary. The authors used bioabsorbable mesh as a spreader or batten graft to support the septum in cleft patients those with weak cartilages. The purpose of this study was to evaluate the efficacy of bioabsorbable mesh when performing septorhinoplasty in cleft patients. METHODS: Between 2009 and 2013, 34 patients with cleft lip and nose underwent open septorhinoplasty by using bioabsorbable mesh at the Konkuk University Medical Center...

Fixation of a bone fracture with a bioabsorbable plate made of poly-L-lactide and hydroxyapatite has received attention. We adopted this technique for a rib fracture by bending the plate into a U-shape and fixing it with suture through the holes in the mesh of the plate and holes that are drilled in the edge of the fractured rib. The suture is also wound around the plate.

Horizontal panniculectomy (PAN) offers the advantage of wide exposure for hernia repair with elimination of excess skin and adiposity, at the expense of massive subcutaneous flap creation and its attendant risks. We report our experience with ventral hernia repair (VHR) with PAN compared with patients with hernia repair alone. A prospective database was reviewed retrospectively for all patients undergoing open VHR + PAN. A matched cohort of patients without PAN was used for comparison, resulting in 43 study and 43 control patients...
