Endoscopic or minimally invasive surgery popular as keyhole surgery is a medical procedure in which endoscope (a camera) is used, and it has gained broad acceptance with popularity in several surgical specialties and has heightened the standard of care. Oral and maxillofacial surgery is a modern discipline in the field of dentistry in which endoscopy has developed as well as widely used in surgeries and is rapidly gaining importance. The use of different visual as well as standard instruments such as laparoscopic and endoscopic instruments, and high-powered magnification devices, has allowed physicians to decrease the morbidity of many surgical procedures by eliminating the need for a large surgical incision...

The aim of this study was to show a different technique for a gasless laparoendoscopic single-site (LESS) hysterectomy and to present advantages and limitations of this technique. Women undergoing gasless LESS hysterectomy with a different technique were evaluated. A total of 14 LESS hysterectomies were performed using this gasless technique and rigid laparoscopic instruments by one surgeon. The mean age of the patients was 48.6 (±4.6). The average blood loss was 80 ± 35 ml. The average time between an umbilical incision and starting hysterectomy was 5 (±2,1) min...

INTRODUCTION: The adoption of robot-assisted laparoscopic (RAL) procedures in the field of urology has occurred rapidly, but is, to date, without pediatric-specific instrumentation. Surgical fog is a significant barrier to safe and efficient laparoscopy. This appears to be a significant challenge when adapting three-dimensional 8.5-mm scopes to use in pediatric RAL surgery. The objective of the present study was to compare matched controls from a prospectively collected database to procedures that were performed utilizing special equipment and a protocol to minimize surgical fog in pediatric RAL procedures...

Spontaneous rupture of the rectum is a rare occurrence. A total laparoscopic approach to rectal perforation has only occasionally been reported. We report an unusual case of a young boy who developed a spontaneous rupture of the rectum following a trivial fall. A magnetic resonance imaging revealed a tear in the rectum at the peritoneal reflection with the omentum plugging it. He denied any history of rectal instrumentation or abnormal sexual activity. He had no history of constipation or rectal prolapse. The tear was repaired laparoscopically and a covering loop sigmoid colostomy was added...

BACKGROUND: The Kymerax© Precision-Drive Articulating Surgical System by Terumo© is a handheld laparoscopic robot which permits motion in two additional degrees of freedom (deflection and rotation in the instrument tip). In a pelvitrainer model, we compared the performance of participants with different laparoscopic experiences and compared Kymerax© to conventional laparoscopic instruments. METHODS: 20 expert surgeons, performing more than 50 laparoscopic procedures per year, and 25 medical students without any experience in surgery at all were selected...

BACKGROUND: Reprocessed (re-sterilized) bipolar energy devices represent one effort to reduce operative costs. METHODS: Between January 2014 to October 2015, 76 patients underwent laparoscopic colectomy using a reprocessed bipolar energy device and were case-matched to 76 patients from a prospectively-maintained database from November 2012 to December 2013 when an identical, new device was used. Outcomes included reprocessed device safety, efficiency and hospital costs...

PURPOSE: The purpose of this paper is to introduce a novel trans-illuminating culdotomy and uterine manipulator device. MATERIALS AND METHODS: The study was a prospective, non-randomized, non-blinded observational clinical study involving 50 female patients undergoing total laparoscopic hysterectomy (TLH) or laparoscopic supracervical hysterectomy (LSH) for benign indications. The surgeries were performed from March through May 2012 at two institutions. The primary study objectives were to demonstrate the safety and adequate clinical performance of the uterine manipulator device and to illustrate its potential widespread future use in minimally invasive gynecologic procedures...

Training of laparoscopic surgery in Virtual Reality (VR) environment has been proved as an effective step before clinical practice. Tracking the position of instruments in realtime is an essential part of developing a VR trainer. In this study, we used Microsoft Kinect and color markers instead of using similar traditional means such as mechanical sensors. The orientation and position of instruments were determined and compared with the results obtained using the SinaSim commercial laparoscopic surgery trainer, which measures these values using encoders...

In this paper, we propose a new method for detecting hemorrhage areas and surgical instruments in robot-assisted laparoscopic surgery images. The proposed scheme utilizes CIELAB information to identify a region of interest (ROI) and segment it. Histogram equalization and Otsu's method are also adopted to compute the detection threshold. Detection is performed automatically and additional adjustment of parameters is not needed. Experiments to verify the proposed algorithm were conducted using actual robot-assisted laparoscopic surgery images...

Laparoscopic surgery for rectal cancer can be technically challenging. We describe a hybrid technique combining abdominal robotic dissection and transanal total mesorectal excision. This procedure was performed in a 50-year-old man with rectal adenocarcinoma at 5 cm from the dentate lane. Preoperative staging was T2N0M0. Surgery went well without complications, and estimated blood loss was less than 50 mL. Robotic surgical time was 90 min, and total operative time was 160 min. The patient was discharged on postoperative day 3...

INTRODUCTION: Sexual dysfunction is common in patients after radical prostatectomy (RP) for prostate cancer. AIM: To provide the International Consultation for Sexual Medicine (ICSM) 2015 recommendations concerning prevention and management strategies for post-RP erectile function impairment in terms of preoperative patient characteristics and intraoperative factors that could influence erectile function recovery. METHODS: A literature search was performed using Google and PubMed databases for English-language original and review articles published up to August 2016...

Laparoscopic supracervical hysterectomy (LSH) is an example of a partial hysterectomy, performed due to benign gynaecological complaints. Better endoscopic instruments and operational techniques have led to a great reduction in the number of abdominal hysterectomies. It is believed that LSH is a safe and minimally invasive hysterectomy technique. The Cochrane Database meta-analysis proves the benefits of minimally invasive surgery compared with abdominal gynaecological surgery, including decreased pain, surgical-site infections and hospital stay, quicker return to activity, and fewer postoperative adhesions...

Laparoscopy has been widely used to perform abdominal surgeries, as it is advantageous in that the patients experience lower post-surgical trauma, shorter convalescence, and less pain as compared to traditional surgery. Laparoscopic surgeries require precision; therefore, it is imperative to train surgeons to reduce the risk of operation. Laparoscopic simulators offer a highly realistic surgical environment by using virtual reality technology, and it can improve the training efficiency of laparoscopic surgery...

This work presents a method to assess and prevent tissue trauma in real-time during surgery. BACKGROUND: Tissue trauma occurs routinely during laparoscopic surgery with potentially severe consequences. As such, it is crucial that a surgeon is able to regulate the pressure exerted by surgical instruments. We propose a novel method to assess the onset of tissue trauma by considering the mechanical response of tissue as it is loaded in real-time. METHODS: We conducted a parametric study using a lab-based grasping model and differing load conditions...

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is the most common bariatric surgery performed worldwide. Improvements in LSG have been suggested to achieve better weight loss or to lessen the complications rates. We propose a change in the standard technique to privilege the use of thinner instruments, the needlescopic sleeve gastrectomy (NSG). METHODS: A 40-year-old female, BMI 40, with no previous abdominal surgery was selected for a NSG. She was placed in a semi-sitting position with the surgeon standing between the legs...
