BACKGROUND: The enhanced-view totally extraperitoneal access technique (eTEP) to minimally invasive retromuscular abdominal wall reconstruction is a relatively novel technique that has continued to gain popularity. There is a paucity of information regarding the prevention and management of eTEP complications. We reviewed the literature to evaluate the complications reported with eTEP ventral hernia repair and discuss the main complications associated with this technique. METHODS: A literature search via PubMed was performed focusing on eTEP ventral hernia repair...

Circuit quantum electrodynamics is one of the most promising platforms for efficient quantum simulation and computation. In recent groundbreaking experiments, the immense flexibility of superconducting microwave resonators was utilized to realize hyperbolic lattices that emulate quantum physics in negatively curved space. Here we investigate experimentally feasible settings in which a few superconducting qubits are coupled to a bath of photons evolving on the hyperbolic lattice. We compare our numerical results for finite lattices with analytical results for continuous hyperbolic space on the Poincaré disk...

We show how quantum many-body systems on hyperbolic lattices with nearest-neighbor hopping and local interactions can be mapped onto quantum field theories in continuous negatively curved space. The underlying lattices have recently been realized experimentally with superconducting resonators and therefore allow for a table-top quantum simulation of quantum physics in curved background. Our mapping provides a computational tool to determine observables of the discrete system even for large lattices, where exact diagonalization fails...

BACKGROUND: Morbidity and recurrence rates are higher in obese patients undergoing open abdominal wall reconstruction (AWR). Historically, body mass index (BMI) ≥ 40 has served as a relative contraindication to open AWR. The purpose of this study is to evaluate the impact of minimally invasive surgery (MIS) on outcomes after AWR for higher versus lower BMI patients. METHODS: A retrospective review of a prospectively maintained database was conducted of all patients who underwent MIS AWR between September 2015 and April 2019 at our institution...

BACKGROUND: The hybrid approach to abdominal wall reconstruction (AWR) for abdominal wall hernias combines minimally invasive posterior component separation and retromuscular dissection with open fascial closure and mesh implantation. This combination may enhance patient outcomes and recovery compared to the open approach alone. The purpose of this study is to evaluate the operative outcomes of hybrid vs. open abdominal wall reconstruction. METHODS: A retrospective review was conducted to compare patients who underwent open versus hybrid AWR between September 2015 and August of 2018 at Anne Arundel Medical Center...

The swift endorsement of the robotic surgical platform indicates that it might prevail as the preferred technique for many complex abdominal and pelvic operations. Nonetheless, use of the surgical robotic system introduces further layers of complexity into the operating theatre necessitating new training models. Instructive videos with relevant exposition could be optimal for early training in robotic surgery and the aim of this study was to develop consensus guidelines on how to report a robotic surgery video for educational purposes to achieve high quality educational video outputs that could enhance surgical training...

BACKGROUND: Building on the principles of eTEP access, described by Dr. Jorge Daes, our group has previously described and standardized a novel minimally invasive approach to restoration of the linea alba and repair of lateral atypical defects of the abdominal wall. The purpose of this report is to present comparative analysis of laparoscopic and robotic eTEP access retrorectus repairs. METHODS: A retrospective review was conducted in patients who underwent laparoscopic eTEP (lap-eRS) and robotic-assisted eTEP (robo-eRS) Rives-Stoppa repairs between September 2015 and May 2018 at our institution...

Background . Giant inguinoscrotal hernias (GIH) are defined as groin hernias extending below the mid-thigh when standing, often significantly encumbering activities of daily living. To date, there are no reports utilizing the combination of progressive pneumoperitoneum (PPP), botulinum toxin A injection (BTI), and enhanced view-totally extraperitoneal (eTEP) technique for GIH repair. In this report, we present 2 such cases of this unique minimally invasive multidisciplinary approach to address GIH. Series Presentation ...

INTRODUCTION: There has been a surge of innovative procedures in the field of abdominal wall hernias. Works of pioneers such as Dr. Yuri Novitsky, Dr. Jorge Daes and Dr. Igor Belyansky have started a new era in the field of hernia surgery. Conventional and popular surgeries for ventral hernias are open onlay mesh hernioplasty, open retromuscular mesh hernioplasty (Rives-Stoppa procedure) and laparoscopic intraperitoneal mesh hernioplasty. Evidence seems to suggest that retromuscular mesh hernioplasty has advantages over other procedures regarding recurrence and surgical site occurrences...

Ideal fixation techniques have not been fully elucidated at the time of complex open abdominal wall reconstruction (AWR). We compared operative outcomes and quality of life with retromuscular mesh fixation using fibrin glue (FG) versus transfascial sutures (TS). Retrospective review identified complex hernia patients who underwent open AWR with mesh from November 2012 through April 2016. Multivariate analysis examined postoperative outcomes between groups. Quality of life was assessed using the Carolinas Comfort Scale...

BACKGROUND: Open abdominal wall reconstruction (AWR) was previously one of the only methods available to treat complex ventral hernias. We set out to identify the impact of laparoscopy and robotics on our AWR program by performing an economic analysis before and after the institution of minimally invasive AWR. METHODS: We retrospectively reviewed inpatient hospital costs and economic factors for a consecutive series of 104 AWR cases that utilized separation of components technique (57 open, 38 laparoscopic, 9 robotic)...

BACKGROUND: The enhanced-view totally extraperitoneal (eTEP) technique has been previously described for Laparoscopic Inguinal Hernia Repair. We present a novel application of the eTEP access technique for the repair of ventral and incisional hernias. METHODS: Retrospective review of consecutive laparoscopic retromuscular hernia repair cases utilizing the eTEP access approach from five hernia centers between August 2015 and October 2016 was conducted. Patient demographics, hernia characteristics, operative details, perioperative complications, and quality of life outcomes utilizing the Carolina's Comfort Scale (CCS) were included in our data analysis...

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: Contaminated operative fields pose significant challenges for surgeons performing ventral hernia repair. Although biologic meshes have been utilized increasingly in these fields, recent evidence suggests that synthetic meshes represent a viable option. We analyzed the outcomes of biologic and synthetic mesh utilized in patients undergoing major ventral hernia repair in clean-contaminated/contaminated fields. METHODS: We conducted a multicenter, retrospective review of patients undergoing open ventral hernia repair in clean-contaminated/contaminated fields using biologic or synthetic mesh...

BACKGROUND: Optimal mesh reinforcement and operative technique for major abdominal wall reconstructions (AWR) remain debatable. Posterior component separation via transversus abdominis release (TAR) allows for wide sublay mesh reinforcement with durable reconstruction, and has been gaining popularity in recent years. Although biologic mesh has been associated with mixed results, outcomes of AWR with bioprosthetics have not been well elucidated to date. We evaluated our outcomes of TAR reconstructions with retromuscular porcine biologic mesh reinforcement...
