Operating Room Awareness with the Smart Trocar: Innovative Laparoscopic Surgery
Laparoscopic surgery is a popular alternative to open surgery due to the considerable reduction of recovery time, pain, scaring, and complications. During laparoscopic surgery, operations are performed through small incisions (usually around 1cm) elsewhere in the body. However, limited access to …

Essential techniques for improving visual realism of laparoscopic surgery simulation.
With the prevalence of laparoscopic surgery, the request for reliable training and assessment is becoming increasingly important. The traditional way of training is both time consuming and cost intensive, and may cause ethical or moral issues. With the development of computer technologies, virtual …

Tumour metastasis and dissemination during laparoscopic surgery / by Susan J. Neuhaus.
… describes cases of metastatic involvement of laparoscopic port sites, not only in patients with advanced tumors but in patients with early stage carcinoma, and even in patients following laparoscopic procedures during which tumors were not disturbed. This thesis utilises an established small …

Context Dependent Gaze Metrics for Evaluation of Laparoscopic Surgery Manual Skills
With the growing adoption of laparoscopic surgery practices, high quality training and qualification of laparoscopic skills through objective assessment has become critical. While eye-gaze and instrument motion analyses have demonstrated promise in producing objective metrics for skill assessment …

Defining the Relationship Between Mechanical Stress and Inadvertent Intestinal Tissue Injury In Laparoscopic Surgery
… of force when handling tissue is much higher in laparoscopic surgery than in open surgical approaches because surgeons lose the ability to directly touch and feel delicate tissue. The two most commonly injured tissues in laparoscopic surgery are the small bowel (55.8%) followed by the large bowel …

Task Analysis, Modeling, And Automatic Identification Of Elemental Tasks In Robot-Assisted Laparoscopic Surgery
<p>Robotic microsurgery provides many advantages for surgical operations, including tremor filtration, an increase in dexterity, and smaller incisions. There is a growing need for a task analyses on robotic laparoscopic operations to understand better the tasks involved in robotic microsurgery …

Effect of Short-Term Postoperative Celecoxib Administration on Patient Outcome After Outpatient Laparoscopic Surgery
… pain management and recovery outcomes following laparoscopic surgery. Methods: Eighty consenting ASA I–III outpatients undergoing laparoscopic surgery were randomly assigned to one of two treatment groups: Control (placebo) or Celecoxib (celecoxib, 400 mg•day-1). The initial dose (celecoxib 400 …

From Music to Medicine: Transfer of Motor Skills from Piano Performance to Laparoscopic Surgery
… the previous project by focussing this time on laparoscopic tasks. This study compared performance curves of two participant groups (pianists and controls) over five consecutive days and retention one week later, as measured by speed and accuracy of task completion. Laparoscopic training …

Using Automated Gaze-Based Feedback to Enhance Motor Skill Acquisition in Laparoscopic Surgery Training
Laparoscopic surgery is now considered the standard of care for many abdominal procedures, offering benefits such as reduced postoperative pain, faster recovery, and shorter hospital stays. However, this type of surgery requires a distinct set of psychomotor skills that are more technically …

Development of a liquid drug delivery payload for modular, wireless, incorporeal robots for laparoscopic surgery
Minimally invasive abdominal surgery (laparoscopy) is performed using long, slender instruments inserted through multiple small incisions in the patient's abdominal wall. This results in less post--operative pain, shorter hospital stays, and a quicker return to normal activities for the patient …

Laparoscopic surgery, I smother the development of programs providing information on the status of the effects of hysterectomy patients(Experience anxiety and nursing center)
자궁은 여성만이 갖고 있는 장기로서 임신, 출산을 가능하게 하는 생식, 분비기관의 기능, 이외에도 여성에게 모성애, 성적 매력, 여성스러움 등 여성의정체감을 갖게하여 완전한 여성으로서의 의미와 역할을 부여하는 상징적 장기이다. 그러므로 자궁자체가 갖는 상징적인 의미로 인해 수술 후 신체적,정신적으로 문제가 초래될 수 있다. 따라서 본 연구는 복강경 질식자궁적출술 환자를 대상으로 수술 전 체계적이고 적절한 교육지침에 의한 간호정보제공 후 그 효과를 규명함으로써 독자적 간호중재를 제공하고 임상에서 활용하여 환자의 수술 전 불안을 …

DEEP REINFORCEMENT LEARNING FOR ROBOT-ASSISTED SURGICAL TRAINING
Minimally invasive surgery (MIS) has the advantage of smaller incision sizes and faster recovery compared to open surgery. Dexterous and complex surgical tools are needed to overcome the limits to operational motion due to smaller incisions. There is also a need to have proficient operation skill …

An Intelligent Guidance System for Computer-Guided Surgical Training
Laparoscopic surgery performed by expert surgeons enables patients to reduce recovery time and pain. However, this surgical procedure is challenging due to restricted vision and depth perception issues. Various simulators have been developed for simulation-based laparoscopic surgery skills …

Complications of anti-reflux surgery in gastro-esophageal reflux disease with special reference to dysphagia
All patients who underwent revision laparoscopic surgery from January 202 to July 2008 in the UCT Private Academic /Groote Scruur Hospital complex for intractable dysphagia and who did not respond to consevative treatment were reviewed. Patients with peri-oesophagel fibrosis as the dominant cause …

Small bowel obstruction and toxicity of a new model of adhesion prevention
… most cases is postoperative abdominal adhesions. Laparoscopic surgery generates less surgical trauma and thereby possibly less adhesion formation and subsequent decreased risk of SBO. The burden of postoperative adhesions is substantial and there is a need for an adhesion preventive agent that can …
