BACKGROUND: Surgeon-performed periarticular injections and anesthesiologist-performed femoral nerve or adductor canal blocks with local anesthetic are in common use as part of multimodal pain management regimens for patients undergoing TKA. However, femoral nerve blocks risk causing quadriceps weakness and falls, and anesthesiologist-performed adductor canal blocks are costly in time and resources and may be unreliable. We investigated the feasibility of a surgeon-performed saphenous nerve ("adductor canal") block from within the knee at the time of TKA...

INTRODUCTION: The risks of exposure to medical ionizing radiation is of increasing concern both among medical professionals and the general public. Patients with nephrolithiasis are exposed to high levels of ionizing radiation through both diagnostic and therapeutic modalities. Endourologists who perform a high-volume of fluoroscopy guided procedures are also exposed to significant quantities of ionizing radiation. The combination of judicious use of radiation-based imaging modalities, application of new imaging techniques such as ultra-low dose computed tomography (CT) scan, and modifying use of current technology such as increasing ultrasound and pulsed fluoroscopy utilization offers the possibility of significantly reducing radiation exposure...

BACKGROUND: Type II focal cortical dysplasia is the most common malformation of cortical development associated with drug resistant epilepsy and susceptible to surgical resection. Although advanced imaging modalities are nowadays capable to detect the majority of such cortical disorders, it is still a challenge for the surgeon to visualize them intraoperatively. The lack of direct boundaries' identification between normal brain and subtle dysplastic tissue may explain poor results in terms of seizure-free patients compared to other forms of epilepsy...

Interventional endoscopy (e.g., bronchoscopy, colonoscopy, laparoscopy, cystoscopy) is a widely performed procedure that involves either diagnosis of suspicious lesions or guidance for minimally invasive surgery in a variety of organs within the body cavity. Endoscopy may also be used to guide the introduction of certain items (e.g., stents) into the body. Endoscopic navigation systems seek to integrate big data with multimodal information (e.g., computed tomography, magnetic resonance images, endoscopic video sequences, ultrasound images, external trackers) relative to the patient's anatomy, control the movement of medical endoscopes and surgical tools, and guide the surgeon's actions during endoscopic interventions...

PURPOSE: Image guidance is a key technology that can improve the outcome of laparoscopic surgery. However, due to the large deformation caused by digestive organs, a computer-aided navigation system based on preoperative imaging data cannot indicate the correct target position of the lesion (e.g., liver tumors and vessels invisible from the organ surface). To overcome this issue, we developed a laparoscopic ultrasound manipulator with two motorized degrees of freedom at the tip, allowing for the performance of a dexterous ultrasound scan in a confined laparoscopic surgical area...

A projector-based augmented reality intracorporeal system (PARIS) is presented that includes a miniature tracked projector, tracked marker, and laparoscopic ultrasound (LUS) transducer. PARIS was developed to improve the efficacy and safety of laparoscopic partial nephrectomy (LPN). In particular, it has been demonstrated to effectively assist in the identification of tumor boundaries during surgery and to improve the surgeon's understanding of the underlying anatomy. PARIS achieves this by displaying the orthographic projection of the cancerous tumor on the kidney's surface...

Glaucoma is a chronic disease caused by the progressive degeneration of the optical nerve fibers, resulting in decreased visual field that can lead to severe visual impairment, and eventually blindness. This manuscript describes a simple, surgeon-friendly, non-incisional technique, named Ultrasound Cyclo Plasty (UCP), for reducing intraocular pressure (IOP) in glaucoma patients. The technique determines a selective coagulation necrosis of the ciliary body; in addition, the stimulation of supra-choroidal and trans-scleral portions of the uveo-scleral outflow pathway has been recently proposed...

INTRODUCTION: Acute ipsilateral shoulder pain (ISP) is a common complaint in patients after thoracotomy. The incidence ranges from 21% to 97%. Unfortunately, clinical studies did not put enough focus on ISP post thoracic surgery. AIM OF THE WORK: This study was designed to compare the effectiveness of suprascapular nerve block (SNB) and phrenic nerve infiltration (PNI) for controlling ISP. PATIENTS AND METHODS: One hundred and thirty-five lung cancer patients (135) scheduled for open-lung surgery were randomly allocated into three equal groups; control group: received thoracic epidural with general anesthesia, suprascapular group: (SNB) one hour before the operation with 10 ml bupivacaine plus thoracic epidural with general anesthesia and phrenic nerve group: (PNI) was performed by the operating surgeon with 10 ml bupivacaine plus thoracic epidural with general anesthesia...

BACKGROUND: Transvaginal surgery is the most minimally invasive surgery for a gynecologic procedure, but it has the limitation of lack of exposure and limited surgical space when utilizing traditional vaginal surgical instrumentation, such as in a hysterectomy for a uterus without descent or for a myomectomy. Transvaginal Nature Orifice Translumenal Endoscopic Surgery (NOTES) offers the similar benefits of traditional vaginal surgery, but also expands the horizon of transvaginal surgery by allowing the surgeon to perform procedures that are typically limited to an abdominal approach...

Background: Mastopexy and reduction mammoplasty are often limited by the patient's poor native soft tissue quality, resulting in ptosis recurrence and loss of rejuvenated surgical results. Surgical scaffolds and acellular dermal matrices are used in these procedures to provide physical and mechanical stabilization of weakened or compromised tissue. GalaFLEX scaffold, made from poly-4-hydroxybutyrate (P4HB), is a next-generation product for soft tissue reinforcement that resorbs gradually while aiding tissue regeneration to achieve excellent outcomes...
