BACKGROUND: Minimally invasive ventral rectopexy is a well-described technique for management of rectal prolapse. Robotic system has proven its advantage for surgeries in the pelvis. Applying this technique, ventral rectopexy can be done more precisely with minimal recurrence. With growing experience, the operative duration and cost of robotic ventral rectopexy can be reduced with better outcome. Few case studies have been described in literature with no study from Indian subcontinent...

BACKGROUND: The application of resistive forces has been used during body weight-supported treadmill training (BWSTT) to improve walking function after spinal cord injury (SCI). Whether this form of training actually augments the effects of BWSTT is not yet known. OBJECTIVE: To determine if robotic-applied resistance augments the effects of BWSTT using a controlled experimental design in a rodent model of SCI. METHODS: Spinally contused rats were treadmill trained using robotic resistance against horizontal (n = 9) or vertical (n = 8) hind limb movements...

Many nanomaterials can be used as sensors or transducers in biomedical research and they form the essential components of transformative novel biotechnologies. In this study, we present an all-optical method for tetherless remote control of neural activity using fully implantable micro-devices based on upconversion technology. Upconversion nanoparticles (UCNPs) were used as transducers to convert near-infrared (NIR) energy to visible light in order to stimulate neurons expressing different opsin proteins. In our setup, UCNPs were packaged in a glass micro-optrode to form an implantable device with superb long-term biocompatibility...

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...

Functional differences in the anterior and posterior hippocampus during episodic memory processing have not been examined in human electrophysiological data. This is in spite of strong evidence for such differences in rodent data, including greater place cell specificity in the dorsal hippocampus, greater sensitivity to the aversive or motivational content of memories in ventral regions, connectivity analyses identifying preferential ventral hippocampal connections with the amygdala, and gene expression analyses identifying a dorsal-ventral gradient...

OBJECTIVE: The aim of this study was to compare length of stay (LOS) after robotic-assisted and open retromuscular ventral hernia repair (RVHR). BACKGROUND: RVHR has traditionally been performed by open techniques. Robotic-assisted surgery enables surgeons to perform minimally invasive RVHR, but with unknown benefit. Using real-world evidence, this study compared LOS after open (o-RVHR) and robotic-assisted (r-RVHR) approach. METHODS: Multi-institutional data from patients undergoing elective RVHR in the Americas Hernia Society Quality Collaborative between 2013 and 2016 were analyzed...

Over the past decade, robotic surgery has gained wide popularity, making a significant impact on multiple surgical specialties. In the head and neck arena, transoral robotic surgery has proven to be safe and associated with acceptable oncological and superior functional outcomes for surgery of the oropharynx, hypopharynx, supraglottis, and glottis; thus, changing the paradigm for the management of tumors in these anatomic locations. Robotic surgery of the ventral skull base is at an early stage of development...

The ligamentous mesometrium is a 3-dimensional structure consisting of a rectouterine/-vaginal part with attachment to the anterior lateral mesorectum and a sacrouterine part surrounding the mesorectum attached to the pelvic fascia and the mesorectum dorsolaterally. The lymphatic network draining the posterior cervix connected caudally ventrally to the deep venous lymph network of the vascular mesometrium is running at the lateral surface of the sacrouterine part and dorsomedially of the inferior hypogastric plexus; it drains to the deep internal iliac, prespinal and preischiadic nodes...

BACKGROUND: Robotic retropubic prostatectomy (RRP) has become one of the most commonly performed robotic procedures in the United States. Ventral hernia (VH) has been increasingly recognized as an important complication after laparoscopic procedures, in general. However, data related to VH after robotic procedures is relatively scarce, especially after RRP. With increasing popularity of RRP, the purpose of this study was to look at the incidence of VH and outcomes of ventral hernia repair (VHR) after RRP...

Laparoscopic ventral mesh rectopexy (LVMR) has proven benefit in the treatment of external rectal prolapse and symptomatic internal rectal prolapse in women. However, there is a recurrence rate of 4-50% depending on indication. Some of this recurrence is attributable to persistent lateral and posterior prolapses. Modifications of LVMR (modified Orr-Loygue rectopexies) describe an additional narrow posterior rectal mesh fixed to the mesorectal fat, which is inherently insecure. Additional complications in men include sexual dysfunction caused by nerve damage from the ventral rectal dissection...

OBJECTIVE The far lateral transcondylar approach to the ventral foramen magnum requires partial resection of the occipital condyle. Early biomechanical studies suggest that occipitocervical (OC) fusion should be considered if 50% of the condyle is resected. In clinical practice, however, a joint-sparing condylectomy has often been employed without the need for OC fusion. The biomechanics of the joint-sparing technique have not been reported. Authors of the present study hypothesized that the clinically relevant joint-sparing condylectomy would result in added stability of the craniovertebral junction as compared with earlier reports...

INTRODUCTION: Minimally invasive laparoscopic and robotic techniques for ventral hernia repair have evolved to achieve the benefits and minimize the limitations of both the open Rives-Stoppa sublay mesh repair and laparoscopic intraperitoneal onlay mesh (IPOM) repair. By combining the principles of a retromuscular repair with the benefits of a minimally invasive approach, these techniques attempt to decrease recurrence, increase functionality, exclude mesh from the viscera, limit infection and wound complications, and minimize pain...

The use of the da Vinci robot for inguinal and ventral hernia repair has exponentially increased over the last five years. This increase is occurring in spite of historical cost analyses showing robotic surgery to be cost prohibitive for other general surgery procedures. Specific data regarding outcomes and cost analysis for hernia is lacking. The increase in robotic hernia repairs is likely related to intangible factors such as enhanced visualization, articulating instruments, and hospital resources. Further study of robotic hernia repair is needed prospectively as its use increases to delineate the true benefits...

BACKGROUND AND OBJECTIVES: The general surgeon's robotic learning curve may improve if the experience is classified into categories based on the complexity of the procedures in a small community hospital. The intraoperative time should decrease and the incidence of complications should be comparable to conventional laparoscopy. The learning curve of a single robotic general surgeon in a small community hospital using the da Vinci S platform was analyzed. METHODS: Measured parameters were operative time, console time, conversion rates, complications, surgical site infections (SSIs), surgical site occurrences (SSOs), length of stay, and patient demographics...

Rectal prolapse is associated with debilitating symptoms and leads to both functional impairment and anatomic distortion. Symptoms include rectal bulge, mucous drainage, bleeding, incontinence, constipation, tenesmus, as well as discomfort, pressure, and pain. The only cure is surgical. The optimal surgical repair is not yet defined though laparoscopic rectopexy with mesh is emerging as a more durable approach. The chosen approach should be individually tailored, taking into account factors such as presence of pelvic floor defects and coexistence of vaginal prolapse, severe constipation, surgical fitness, and whether the patient has had a previous prolapse procedure...
