Interface-interaction induced self-healing and self-adhesive are a gem-like attribute inspired by our Mother Nature. Biocompatible gelatin methacrylate (GelMA) hydrogels exhibit tunable mechanical properties which are favorable in biomedical applications. However, it is difficult to integrate high stiffness, super-elasticity, large deformability and self-healing property together. Here, we report a GelMA-based double-network (DN) hydrogel with above properties by utilizing tannic acid (TA) as a multi-functional H-bond provider...

PURPOSE: To describe a new surgical modality, "Bowman membrane tuck-in," for management of small to medium sized corneal perforation of a noninfectious etiology. METHODS: Two patients with corneal perforation of a noninfectious etiology and less than 4 mm in size underwent Bowman membrane tuck-in, a new surgical procedure. In this technique, Bowman membrane harvested from the donor cornea was tucked inside the stromal pocket of host tissue, which was prepared by 360-degree anterior stromal lamellar dissection...

Two eyes of 2 patients with macular hole-associated retinal detachment in clinically diagnosed vitelliruptive stage of Best vitelliform dystrophy were surgically managed by 25-gauge sutureless pars plana vitrectomy, internal limiting membrane (ILM) peeling with inverted ILM flap, and short-acting (SF6 ) gas tamponade. The patients were assessed with respect to best-corrected visual acuity, color fundus photographs, shortwave fundus autofluorescence, and swept source optical coherence tomography. Surgical intervention led to Type 1 closure of macular hole, resolution of retinal detachment, and improvement in vision in both patients...

Total anomalous pulmonary venous connection is a rare congenital heart disease. The development of pulmonary venous obstruction is one of the major risk factors for poor outcomes after surgical repair. Sutureless pericardial repair for a total anomalous pulmonary venous connection was introduced to decrease the risk of pulmonary venous obstruction after surgical repair, and favourable outcomes have been reported. Herein, we report the case of an infant with a total anomalous pulmonary venous connection who developed pulmonary venous obstruction after primary sutureless pericardial repair...

OBJECTIVES: The Sutureless and Rapid-Deployment Aortic Valve Replacement International Registry (SURD-IR) was established by a consortium of 18 research centres-the International Valvular Surgery Study Group (IVSSG)-to overcome limitations of the literature and provide adequately powered evidence on sutureless and rapid-deployment aortic valves replacement (SURD-AVR). METHODS: Data from 3343 patients undergoing SURD-AVR over a 10-year period (2007-2017) were collected in the registry...

AIM: To evaluate the safety and efficacy profile of 27-gauge (27G) pars plana vitrectomy (PPV) for the treatment of various vitreoretinal diseases. METHODS: The clinical outcomes of 61 eyes (58 patients) with various vitreoretinal diseases following 27G PPV were retrospectively reviewed. RESULTS: Surgical indications included rhegmatogenous retinal detachment ( n =24), full-thickness macular hole ( n =12), diabetic retinopathy ( n =11), vitreous hemorrhage ( n =6), Eales disease ( n =4), pathological myopia-related vitreous floater ( n =2), and macular epiretinal membrane ( n =2)...

Minimally invasive aortic valve replacement (AVR) is increasingly being adopted worldwide, in which a right mini-thoracotomy (RT) approach plays an important role. Here we reported a novel technique of AVR via RT using sutureless prosthesis, without rib division or groin incision. Surgical access was performed through an anterior right thoracotomy with 5-cm skin incision placed in the third intercostal space. Percutaneous femoral-femoral cardio-pulmonary bypass (CPB) was applied under fluoroscopy guidance to avoid groin incision...

Purpose: This study aims to evaluate the incidence and risk factors for vitreous rebleed (VRB) following 25-gauge sutureless vitrectomy for vitreous hemorrhage (VH) in diabetic retinopathy. Methods: A retrospective review of 190 diabetic patients having undergone vitrectomy for VH at a tertiary eye care center was analyzed. Demographic data of patients along with risk factors such as blood sugar levels (BSL), blood pressure (BP), anticoagulant use, and pan-retinal photocoagulation status (PRP) were tabulated...

BACKGROUND: The optimal management and prognostic factors of postsurgical pulmonary vein stenosis remain controversial. We sought to determine current postsurgical pulmonary vein stenosis outcomes and prognostic factors in a multicentric study in the current era. METHODS: Seventy-five patients with postsurgical pulmonary vein stenosis who underwent 103 procedures in 14 European/North American centers (2000-2012) were included retrospectively. A specific pulmonary vein stenosis severity score was developed on the basis of the assessment of each pulmonary vein...

In elderly, high-risk surgical patients, sutureless aortic valve replacement (AVR) can often be an alternative to conventional AVR; shorter aortic cross-clamp and cardiopulmonary bypass times are the chief advantages. We compared the outcomes of sutureless AVR with those of conventional AVR in 70 elderly patients who underwent concomitant cardiac surgical procedures. We retrospectively analyzed the cases of 42 men and 28 women (mean age, 70.4 ┬▒ 10.3 yr; range, 34-93 yr) who underwent cardiac operations plus AVR with either a sutureless valve (group 1, n=38) or a conventional bioprosthetic or mechanical valve (group 2, n=32)...

OBJECTIVES: Sutureless aortic valve replacement (SU-AVR) is an alternative technique to standard aortic valve replacement. We evaluated our experience with the Perceval SU-AVR with concomitant mitral valve surgery, with or without tricuspid valve surgery, and aimed to discuss the technical considerations. METHODS: From January 2013 through June 2016, 30 patients with concomitant severe mitral valve disease, with or without tricuspid valve disease, underwent SU-AVR with the Perceval prosthesis in a single center...

INTRODUCTION: The Harmonic scalpel ("Focus" and the new version "Focus+") is one of the first devices for surgical simultaneous cutting and tissue coagulation which allows to obtain dissection and hemostasis by direct application of ultrasound and allows minimally invasive surgical procedures with minimal lateral thermal spread and, thus, minimal adjacent tissue destruction. The aim of the study is to complete the previous study that we made in 2014, based on the TT performed between January 2008 and December 2013, with new data about TT performed in our Surgical Division between January 2014 and December 2016 and compare the outcome using the Ultrasonic scalpel versus the device Ligasure in term of safety, operative time, overall drainage volume, complications, hospital stay...

OBJECTIVES: This meta-analysis was conducted to compare the early and follow-up outcomes of aortic valve replacement using rapid deployment or sutureless (RD) valves (RDAVR group) with aortic valve replacement using conventional bioprostheses (CAVR group). METHODS: A literature search of 5 online databases was conducted. The primary outcomes were postoperative complications and the secondary outcomes included the aortic cross-clamp (ACC) and cardiopulmonary bypass (CPB) times and early mortality and all-cause mortality during follow-up...

PURPOSE OF REVIEW: The surgical approach to eyes needing a secondary intraocular lens have evolved rapidly in recent years. Here, we will focus on techniques for scleral-fixation of intraocular lenses (IOLs), and will review the evidence for their safety and efficacy. RECENT FINDINGS: Transscleral fixation of IOLs refers the placement of lens haptics within scleral tunnels to stabilize the lens in eyes that lack adequate capsular support. Various surgical techniques have been reported recently to accomplish this goal...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) delivers cardiac and/or respiratory support to critically ill patients who have failed conventional medical therapies. If the large-bore cannulas used to deliver ECMO become infected or dislodged, the patient consequences can be catastrophic. ECMO cannula-related infection has been reported to be double the rate of other vascular devices (7.1 vs 3.4 episodes/1000 ECMO days respectively). The aim of this study was to assess the ability of cyanoacrylate tissue adhesive (TA) to inhibit bacterial growth at the ECMO cannulation site, and the effectiveness of TA and securement devices in securing ECMO cannulas and tubing...
