OBJECTIVE: To evaluate a new magnetic surgical system during reduced-port laparoscopic cholecystectomy in a prospective, multicenter clinical trial. BACKGROUND: Laparoscopic instrumentation coupled by magnetic fields may enhance surgeon performance by allowing for shaft-less retraction and mobilization. The movements can be performed under direct visualization, generating different angles of traction and reducing the number of trocars to perform the procedure. This may reduce well-known associated complications of trocars, including incisional pain, scarring, infection, bowel, and vascular injuries, among others...

The concept of complete mesocolic excision and central vascular ligation for colonic cancer has been recently introduced. The paper describes a technique of right-sided complete mesocolic excision and intracorporeal anastomosis by using a single-port robotic approach with an additional conventional robotic port. We performed a single-port plus an additional port robotic surgery using the Da Vinci Single-Site platform via the Pfannenstiel incision and the wristed robotic instruments via an additional robotic port in the left lower quadrant...

OBJECTIVES: The objectives of this study were to (1) create a technical and nontechnical performance standard for the laparoscopic cholecystectomy, (2) assess the classification accuracy and (3) credibility of these standards, (4) determine a trainees' ability to meet both standards concurrently, and (5) delineate factors that predict standard acquisition. BACKGROUND: Scores on performance assessments are difficult to interpret in the absence of established standards...

INTRODUCTION: Single-incision laparoscopic colectomy is technically limited because of such factors as instrument crowding, in-line viewing, and insufficient countertraction. In particular, it is technically difficult to cut the distal rectum from the umbilicus using an articulating linear stapler in single-incision laparoscopic anterior resection. TECHNIQUE: After treating the mesorectum, the 5-mm trocar is replaced with a 12-mm trocar. The cartridge of the curved stapler is mounted while the shaft of the stapler is inserted into the 12-mm port extracorporeally...

OBJECTIVE: To explore the feasibility of an oncologically acceptable management for an intermediate-risk endometrial cancer (EC) in an elderly, using the combination of transvaginal single-port laparoscopy and sentinel node policy. METHODS: For this 85-years old patient, BMI 32kg/m(2), with IB grade 2 endometrioid EC, a single vaginal approach was attempted [1] to perform a total hysterectomy, bilateral salpinago-oophorectomy and pelvic node assessment guided by SND [2]...

BACKGROUND: Duodenum diverticulum is the most common site for diverticular disease of small intestine. Most of duodenal diverticulum are asymptomatic, but complicated or perforated duodenal diverticulum is rare. Nonoperative management is attractive in selected patients, because of higher surgical complications. We suggest the use of a minimally invasive operative method as an alternative approach for the management of complicated duodenal diverticulum, especially when conservative treatment has failed...

BACKGROUND: Single-port laparoscopy is a step forward toward nearly scar less surgery. Concern has been raised that single-incision laparoscopic surgery (SILS) is technically more challenging because of the lack of triangulation and the clashing of instruments. Robotic single-incision laparoscopic surgery (RSILS) in chopstick setting might overcome these problems. This study evaluated the outcome in time and errors of two tasks of the Fundamentals of Laparoscopic Surgery on a dry platform, in two settings: SILS versus RSILS...

INTRODUCTION: Minimally invasive surgery has become an important aspect of Pediatric Urology fellowship training. In 2014, the Accreditation Council for Graduate Medical Education published the Pediatric Urology Milestone Project as a metric of fellow proficiency in multiple facets of training, including laparoscopic/robotic procedures. OBJECTIVE: The present study assessed trends in minimally invasive surgery training and utilization of the Milestones among recent Pediatric Urology fellows...

INTRODUCTION: Kyphoscoliosis, which is a deformity of the spine caused by aging and osteoporosis, results in various surgical difficulties for laparoscopic cholecystectomy (LC) due to low-lying costal arches, such as a small abdominal working space, disturbance of the surgical view and decreased controllability of the surgical instrument. PRESENTATION OF CASE: We herein report the case of a 92-year old woman with severe kyphoscoliosis who was diagnosed with Grade II acute cholecystitis...

OBJECTIVE: To describe a laparoscopic technique for evaluating umbilical disorders in calves, including feasibility, visualization of umbilical structures, and related complications. STUDY DESIGN: Prospective clinical study. ANIMALS: Male calves (15 Holstein, 2 Montbeliard) with umbilical disorders (n=17). METHODS: Calves <2 months old with obvious umbilical disease were assessed by clinical examination and ultrasonography of the umbilical structures...

INTRODUCTION: Laparoscopic percutaneous extraperitoneal closure (LPEC) in boys is more complex than in girls, because the vas deferens and testicular vessels must be separated from the peritoneum. We therefore developed a needle-shaped surgical instrument that enables blunt separation. Here, we report the effectiveness of this new device. SURGICAL TECHNIQUE: The new device is a ligature carrier consisting of (1) an inner tube (19-G blunt needle) through which slides a rod with a loop wire at its tip that can catch and release suture materials and (2) an outer tube (17-G needle) with a cutting edge...

OBJECTIVE: Laparoscopic surgery is the current accepted approach in most pediatric surgical centers. In an attempt to further minimize the surgical trauma and improve cosmetic outcome, new techniques with a single incision through the umbilicus have been proposed and we believe they will become the standard choices for pediatric surgery. This report describes our initial experience with transumbilical single-incision laparoscopic surgery (TSILS) in children with conventional instruments...

BACKGROUND: Mental skills training refers to the implementation of cognitive performance-enhancing strategies to promote optimal performance. We aimed to develop a surgery-specific mental skills curriculum (MSC) and obtain initial evidence of efficacy. METHODS: The developed MSC consisted of 8 proven performance-enhancing modules. Its efficacy was assessed during laparoscopic simulator-based practice by novices using validated instruments of mental skills, workload, and stress, in addition to a skill transfer test to a porcine model...

BACKGROUND: Minimally invasive surgery (MIS) is rising in popularity generating a revolution in operative medicine during the past few decades. Although laparoscopic techniques have not significantly changed in the last 10 years, several advances have been made in visualization devices and instrumentation. METHODS: Our team, composed of surgeons and biomedical engineers, developed a magnetic levitation camera (MLC) with a magnetic internal mechanism dedicated to MIS...

OBJECTIVE: To report the surgical technique and outcome of dogs undergoing laparoscopic adrenalectomy for removal of unilateral noninvasive pheochromocytoma. STUDY DESIGN: Retrospective case series. ANIMALS: Dogs with unilateral noninvasive adrenal tumors (n=10). METHODS: Medical records of dogs that underwent laparoscopic adrenalectomy for histologically confirmed pheochromocytoma were reviewed. Dogs were positioned in lateral recumbency with the table tilted up to create a semi-sternal position...

Diseases of the lower and middle third of the rectum, the so called "no-man's territory" traditionally represent a major surgical problem. Minimally invasive surgical techniques significantly contribute to the safe and precise management of this part of the rectum. Traditional laparoscopic instruments via a specifically designed operative anoscope with single-port surgical technique are used during TAMIS (transanal endoscopic minimally invasive surgery). Since the description of the procedure in 2009 a number of case series have proven the feasibility and safety of the technique in the treatment of rectal adenomas...

BACKGROUND: Emergency general surgery is associated with high morbidity and mortality but has seldom been targeted for practice improvement. The goal of this study was to determine whether perioperative practices vary among surgeons for emergency Hartmann's procedures and whether perioperative care practices are associated with hospitals' complication rates. MATERIALS AND METHODS: We conducted a survey of surgeons at 27 Michigan hospitals. Questionnaires focused on preoperative, intraoperative, and postoperative care practices...
